Personalized and real-time image captioning enhances user experience by adapting captions to preferences and delivering dynamic descriptions for changing content. Personalized systems leverage user profiles, fine-tune models on specific data, and incorporate feedback loops or natural language understanding for tailored outputs, benefiting accessibility tools, e-commerce, and social media. Real-time captioning uses low-latency models, temporal analysis, event detection, and multimodal inputs to generate fast, accurate captions for videos, live streams, and dynamic environments like surveillance or education. While challenges like privacy, scalability, and latency persist, advancements in ethical AI and optimized architectures promise seamless and user-centric solutions.
Relevant answer
Answer
Okay, let's break down personalized and real-time image captioning, focusing on the "how":
1. Personalized Image Captioning (Adapting to User Preferences):
  • Core Idea: Tailor captions to individual users, not just describe the image objectively.
  • Key Techniques: User Profiling: Explicit Feedback: User ratings ("like," "dislike"), preferred keywords, or edits to captions. Implicit Data: Browsing history, past interactions with captions, demographics. Model Fine-tuning: Transfer Learning: Start with a general model, fine-tune it on data associated with specific users (or groups). Personalized Embeddings: Learn unique vector representations for each user to bias caption generation. Content-Aware Personalization: Attention Mechanisms: Focus on image regions relevant to user's preferences. Personalized Vocabulary: Use words or language style that align with each user's history. Reinforcement Learning (RL): Train the model to maximize rewards based on user satisfaction (e.g., user engagement with captions). Natural Language Understanding (NLU) : Use NLU to understand user queries or requests to produce contextually relevant captions.
  • Example: A user who always searches for "vintage cars" will get captions emphasizing the car's era rather than a generic description.
2. Real-Time Captioning (Dynamic Content):
  • Core Idea: Generate captions quickly and accurately for constantly changing visuals (videos, live streams).
  • Key Techniques: Low-Latency Models: Lightweight Architectures: Use simpler models (e.g., MobileNets) for faster inference. Model Pruning/Quantization: Reduce model size and computations. Temporal Analysis: Video Frame Sequences: Analyze frames over time to maintain context and track object movement. Recurrent Neural Networks (RNNs): Capture temporal dependencies in the video. Event Detection: Object Tracking: Identify and track moving objects across frames. Action Recognition: Detect actions (e.g., "person jumping," "dog running"). Multimodal Input: Audio Input: Combine visual data with audio (e.g., spoken words in a video). Text Input: Use textual metadata or subtitles (if available). Adaptive Processing: Adjust model processing speed based on content complexity. Dynamically allocate resources based on processing requirements.
  • Example: Captioning a live sporting event with descriptions of actions (e.g., "player scores a goal").
Challenges and Future Directions :
  • Personalization: Privacy: How to handle user data responsibly. Scalability: How to efficiently create and maintain user profiles. Cold Start Problem: How to handle new users with no prior history.
  • Real-Time: Latency: Balancing accuracy with fast processing. Dynamic Scenes: Handling rapidly changing and cluttered environments. Robustness: Making models less sensitive to noise or low image quality.
  • Both: Ethical AI: Ensuring captions are unbiased and fair. User-Centered Design: Creating solutions that meet the needs of different user groups.

ChatGPT reveals that while its story begins around 2015, its current capabilities are the result of years of research, development, and most significantly learning from vast amounts of data, per the below.
· GPT-1 – June 2018 (117 million parameters)
· GPT-2 – February 2019 (1.5 billion parameters)
· GPT-3 – June 2020 (175 billion parameters)
· GPT-3.5 – November 2022 (further refinements on GPT-3)
· GPT-4 – March 2023 (multimodal, improved reasoning)
· GPT-4 Turbo – November 2023 (faster, more cost-efficient variant)
Turbo, the last version, is the prime engine processing all queries since its release, both paid and unpaid. This vast amount of data includes the near totality of human savoir-faire, professional and scientific knowledge bases in all fields, to the point that it can pass strict professional exams and write theses at the doctorate level.
The question is: with this humongous amount of data, and their extensive language-based reasoning capabilities, why have we not seen any scientific breakthrough by these LLM’s in nearly 15 years of fending on their part altogether? Does that say something about our model of science (scientific method), and the value and validity of what we know in science, in particular the fundamental premises in all disciplines? Is this a verdict on the quality of what we know in terms of our scientific principles? In light of this null result, can we expect what we know to tell us something in the least amount about or toward the resolution of what we don’t know? If there is a hard breaking between our knowns and the unknowns, can the LLM’s help at all leapfrog the barrier? Given ceiling being currently hit in their learning capacity, would more time make any difference?
Relevant answer
Answer
The so-called training provides them with a sense of association between elements of the data sets, and an ability to synthesize the same, which you could all call reasoning. Association and synthetic training have also enabled them for pattern recognition. Yes, they do fail in spatial visualization. Yet they are able to make close graphic representations to what is requested from them by prompters. While it may be true that other methods can help spur their analytic and composition skills, one must acknowledge that passing strict medical exams is not a insignificant achievement.
The question remains why in almost 2 decades, no scientific breakthrough had come along with them.

Question

The spot diameter of the signal light is 1.3mm, and the collimating lens is a flat convex lens with a focal length of 11mm. The spot is measured by a spot quality analyzer, and the spot is measured 10cm away from the collimator. It is found that the spot is concentric circle type and the spot diameter is about 15μm after the collimating lens is focused. The large-mode optical fiber is liekki passive 30/250 dc pm with core NA of 0.07. Cut both ends of the optical fiber by 8°.
In the experiment, the collimated light beam is deflected through the half-wave plate and PBS, and then the optical fiber axis is used after passing through the second half-wave plate. The passive fiber is placed on the five-dimensional adjusting frame, and the output end of the passive fiber is collimated through a flat-convex lens with a focal length of 15mm. The output light spot can obviously see the panda eye spot, and there is no obvious bright spot in the center of the light spot, indicating that most of the signal light has entered the cladding, and the extinction ratio is only 1dB.
I have three questions:
1. If the signal is a fundamental mode Gaussian beam (actually a concentric ring type), it can be fully coupled into the core according to the formula, but the coupling effect is very poor at present, why?
2. How to measure the result of coupling? Is the output light spot periphery has entered the envelope of the diaphragm filter, and then measure the coupling efficiency, so that the extinction ratio is not taken into account. The goal of coupling is to get as much signal light into the core as possible with high coupling efficiency while maintaining a high extinction ratio for the output. The current experiments are sometimes more efficient, but the extinction ratio is worse.
3. If the passive fiber is replaced by a gain fiber, model liekki y1200 30/250 dc pm, how should the coupling result be measured? At this time, the signal light will have higher absorption in the core and less absorption in the cladding, and the coupling efficiency seems to be inappropriate.
I hope you can answer. If there are skills and experiences about spatial optical coupling into large mode field polarization-maintaining fibers, I also hope to share them.

How does an amphibious robot with two sets of power units rationally switch between them? Or the modal switching problem for multimodal robots?
Relevant answer
Answer
Multimodal robots are those that can operate in different environments using different locomotion methods. For example, a robot that can drive on land and swim underwater is a multimodal robot.
The modal switching problem refers to the challenge of deciding when and how to switch between these different locomotion modes. This is a complex issue because each mode has its own advantages and limitations.
Here are some key aspects of the modal switching problem:
  • Planning: The robot needs to consider factors like terrain, obstacles, and its destination to determine the most efficient path that might involve switching locomotion modes.
  • Transitioning: Switching between modes can be complex and might require finding a specific transition configuration where both modes are operational.
  • Feasibility: Not all mode switches might be feasible in every situation. The robot needs to ensure a smooth and safe transition between modes.
Solving the modal switching problem is crucial for enabling smooth and efficient operation of multimodal robots in various environments. Researchers are exploring different approaches like motion planning algorithms and optimization techniques to address this challenge.

How does multimodal monitoring contribute to TBI management, and what modalities are typically included?
Relevant answer
Answer
Multimodal monitoring plays a crucial role in traumatic brain injury (TBI) management by providing comprehensive and real-time information about various aspects of cerebral physiology. This approach allows clinicians to tailor treatment strategies based on individual patient needs and optimize outcomes. Several modalities are typically included in multimodal monitoring for TBI:
  1. Intracranial Pressure (ICP) Monitoring: Measurement of ICP provides valuable information about intracranial dynamics and helps guide interventions to prevent secondary brain injury. Elevated ICP is a common complication of TBI and can lead to cerebral ischemia, herniation, and poor outcomes. Continuous monitoring of ICP allows for early detection of intracranial hypertension and prompt intervention to mitigate its effects.
  2. Cerebral Perfusion Pressure (CPP) Monitoring: CPP is calculated as the difference between mean arterial pressure (MAP) and ICP and reflects the pressure gradient driving cerebral blood flow. Maintaining adequate CPP is essential to ensure sufficient cerebral perfusion and oxygen delivery to the injured brain tissue. CPP monitoring helps guide interventions aimed at optimizing cerebral blood flow and preventing ischemia.
  3. Brain Tissue Oxygenation (PbtO2) Monitoring: Measurement of brain tissue oxygenation provides information about the balance between oxygen supply and demand in the injured brain tissue. PbtO2 monitoring helps identify regions of ischemia or hypoxia and guides interventions to improve oxygen delivery, such as optimizing CPP, ensuring adequate hemoglobin levels, and managing systemic factors affecting oxygenation.
  4. Cerebral Blood Flow (CBF) Monitoring: Techniques such as transcranial Doppler ultrasound or thermal diffusion flowmetry can be used to monitor cerebral blood flow in real-time. Monitoring CBF helps assess the adequacy of cerebral perfusion and guide interventions to optimize blood flow and prevent ischemia or hyperemia.
  5. Electroencephalography (EEG): Continuous EEG monitoring provides information about cerebral electrical activity and helps detect seizures, ischemia, or spreading depolarizations that may not be evident clinically. EEG monitoring can guide treatment with antiepileptic drugs and inform prognosis in TBI patients.
  6. Near-Infrared Spectroscopy (NIRS): NIRS measures regional cerebral oxygen saturation (rSO2) and provides information about cerebral oxygenation and hemodynamics. NIRS monitoring can help identify changes in cerebral perfusion and guide interventions to optimize oxygen delivery to the brain.
  7. Brain Tissue pH Monitoring: Monitoring of brain tissue pH using microdialysis catheters provides information about tissue acid-base balance and metabolism. Changes in brain tissue pH can indicate ischemia or metabolic dysfunction and guide interventions to optimize cerebral metabolism.
  8. Neuromonitoring with Advanced Imaging Techniques: Advanced imaging modalities such as diffusion tensor imaging (DTI), functional MRI (fMRI), and positron emission tomography (PET) can provide valuable insights into structural and functional changes in the injured brain. These techniques help assess the extent of injury, predict outcomes, and guide rehabilitation strategies.
By integrating data from multiple monitoring modalities, clinicians can obtain a comprehensive understanding of cerebral physiology and tailor treatment strategies to optimize cerebral perfusion, oxygenation, and metabolism in TBI patients. This personalized approach improves the likelihood of favorable outcomes and minimizes the risk of secondary brain injury.

Discuss the use of multimodal analgesia techniques, including oral analgesics, regional techniques, and non-pharmacological interventions, for postpartum pain management.
Multimodal analgesia involves the use of multiple analgesic modalities in combination to optimize pain relief while minimizing the adverse effects associated with any single agent. In the postpartum period, multimodal analgesia is particularly beneficial for managing pain following both vaginal delivery and cesarean section.
Relevant answer
Answer
Multimodal analgesia involves the use of multiple analgesic modalities in combination to optimize pain relief while minimizing the adverse effects associated with any single agent. In the postpartum period, multimodal analgesia is particularly beneficial for managing pain following both vaginal delivery and cesarean section. Here's a discussion of the various multimodal analgesia techniques used for postpartum pain management:
  1. Oral Analgesics:Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs such as ibuprofen, diclofenac, or ketorolac are commonly used for postpartum pain relief due to their analgesic and anti-inflammatory properties. They can effectively reduce pain intensity and inflammation, particularly after episiotomy or perineal tears following vaginal delivery. Acetaminophen (Paracetamol): Acetaminophen is another oral analgesic option used alone or in combination with NSAIDs for postpartum pain management. It provides effective pain relief for mild to moderate pain and is generally well-tolerated, making it suitable for breastfeeding mothers.
  2. Regional Analgesia Techniques:Epidural Analgesia: Epidural analgesia involves the administration of local anesthetic and opioid medications into the epidural space to provide effective pain relief during labor, vaginal delivery, and cesarean section. Continuous epidural analgesia can be maintained postoperatively to provide prolonged pain relief in the first 24-48 hours after cesarean section. Spinal Analgesia: Spinal analgesia, also known as intrathecal analgesia, involves the injection of a single dose of local anesthetic and opioid medications into the intrathecal space to provide rapid and potent pain relief. It is commonly used for cesarean section and can also be used for postoperative pain management. Patient-Controlled Analgesia (PCA): Patient-controlled epidural analgesia (PCEA) or patient-controlled intravenous analgesia (PCIA) allows patients to self-administer bolus doses of local anesthetic or opioid medications through a programmable infusion pump. This method empowers patients to actively participate in their pain management and can improve pain control while reducing opioid consumption.
  3. Non-Pharmacological Interventions:Positioning: Encouraging comfortable positions, such as side-lying or semi-Fowler's position, can alleviate discomfort and promote relaxation. Cold Therapy: Application of ice packs or cold packs to the perineum or incision site can reduce swelling and inflammation and provide temporary pain relief. Heat Therapy: Application of warm compresses or heating pads to the perineum or abdomen can help relieve muscle soreness, cramping, and discomfort. Relaxation Techniques: Deep breathing exercises, guided imagery, relaxation, and distraction techniques can help manage pain and promote relaxation in the postpartum period.
By combining oral analgesics, regional analgesia techniques, and non-pharmacological interventions in a multimodal analgesic regimen, healthcare providers can effectively manage postpartum pain while minimizing opioid consumption and its associated side effects. Individualized pain management plans tailored to each patient's needs and preferences can optimize maternal comfort and promote early recovery in the postpartum period.

Relevant answer
Answer
The management of perioperative pain in paediatric patients is a critical aspect of their care, aiming to minimize discomfort, improve recovery, and reduce the risk of complications. An effective approach often involves a combination of pharmacological agents, regional anaesthesia techniques, and multimodal analgesia strategies tailored to the individual patient and surgical procedure. Here's a discussion on the management of perioperative pain in paediatric patients, including the use of regional anaesthesia techniques and multimodal analgesia:
  1. Pharmacological Agents:Opioid Analgesics: Opioids such as morphine, fentanyl, and hydromorphone are commonly used for moderate to severe pain management in paediatric patients. They provide effective analgesia but may be associated with side effects such as respiratory depression, sedation, and gastrointestinal disturbances. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs like ibuprofen and ketorolac are useful for mild to moderate pain relief and have anti-inflammatory properties. They are often used as adjuncts to opioids, helping to reduce opioid requirements and minimize opioid-related side effects. Acetaminophen (Paracetamol): Acetaminophen is a widely used analgesic and antipyretic agent in paediatric patients. It is generally well-tolerated and can be administered orally, rectally, or intravenously for perioperative pain management. Local Anaesthetics: Local anaesthetic agents such as lidocaine or bupivacaine may be used for infiltration at the surgical site or for regional nerve blocks to provide targeted pain relief and reduce the need for systemic analgesics.
  2. Regional Anaesthesia Techniques:Peripheral Nerve Blocks: Peripheral nerve blocks involve the infiltration of local anaesthetic agents around peripheral nerves to provide regional analgesia. Common nerve blocks in paediatric patients include caudal epidural block, ilioinguinal/iliohypogastric nerve block, femoral nerve block, and brachial plexus block. Continuous Peripheral Nerve Catheters: Continuous peripheral nerve catheters allow for prolonged analgesia by continuously infusing local anaesthetic solutions near the target nerve. They are often used for postoperative pain management in paediatric patients undergoing major orthopedic procedures or abdominal surgeries. Epidural Analgesia: Epidural analgesia involves the placement of an epidural catheter in the epidural space to deliver local anaesthetic agents or opioid medications for pain relief. It is commonly used for major abdominal or thoracic surgeries in paediatric patients.
  3. Multimodal Analgesia:Combination Therapy: Multimodal analgesia involves the use of multiple analgesic agents with different mechanisms of action to target pain pathways at various levels. Combining opioids with NSAIDs, acetaminophen, or regional anaesthesia techniques allows for synergistic effects and reduced reliance on any single agent. Preemptive Analgesia: Preemptive analgesia aims to prevent the establishment of central sensitization and hyperalgesia by administering analgesic medications or regional anaesthesia techniques before the onset of surgical stimuli. This proactive approach can lead to improved pain control and reduced postoperative opioid requirements. Patient-Controlled Analgesia (PCA): PCA allows paediatric patients to self-administer predetermined doses of intravenous opioid analgesics through a programmable infusion pump. It provides patients with a sense of control over their pain management while ensuring safety and titratability of analgesic dosing.
  4. Assessment and Monitoring:Regular assessment of pain intensity using age-appropriate pain scales (e.g., Faces Pain Scale, Numeric Rating Scale) is essential for guiding analgesic therapy and evaluating treatment effectiveness. Continuous monitoring of vital signs, sedation levels, and opioid-related side effects (e.g., respiratory depression, nausea, pruritus) is necessary to ensure safe and optimal pain management.
In summary, the management of perioperative pain in paediatric patients requires a comprehensive and individualized approach that integrates pharmacological agents, regional anaesthesia techniques, and multimodal analgesia strategies. By addressing pain proactively and effectively, healthcare providers can improve patient comfort, expedite recovery, and enhance overall perioperative outcomes in paediatric surgical patients.

Based on the my personal Gemini Ultra test results, I can say that GPT-4v is definitely better than Gemini Ultra!!!
The hype around the absolute benefits of Gemini Ultra is just a purely business PR campaign that mainly misleads users and tries to pass off wishful thinking. The multimodal capabilities of the Gemini Ultra v 1.0 are actually very limited and do not meet the requirements. At the same time, ideally, it is necessary to use these different LLMs, supplementing the gaps of one with the advantages of the other.

Hi guys,
I have a Holmium doped multimode fibre with a double cladding structure. But my available pump is only modest so without core pumping we won’t get amplification. What is the best way to check if the pump beam is efficiently coupled into the core?
The pump beam was conjugated from the 6 um core diameter SMF, expanded to about 35 um which is lightly smaller than the fibre core (40 um) using a pair of lens.
I am trying to look at the image at the other end, hoping to see the ASE glowing when the pump beam is strongly coupled to the core, as well as a minumum in total pump transmitted power. But do you know some more elegant way of doing this?
Thank you,
L
Relevant answer
Answer
Linh - I think the way to see the pump coupled is to connect the other end of fibre to a spectrum analyzer, scanning fast over a small optical bandwidth where you expect to see the light (pump or fluorescence) - if noise floor is ~-90 dBm, you should be able to see the coupled light signal increasing as you play with micropositioners/angles. Best regards, Misha.

Businesses are looking for more affordable and effective ways to move goods across borders as trade barriers are being lowered and global supply chains become more complex. In this situation, multimodal transportation offers flexibility and optimisation.
Third, environmental concerns are driving the need for more environmentally friendly transportation options. Utilising a combination of modes, such as trains or ships for long-distance travel segments, which produce less greenhouse gases than cars or airplanes, can be more environmentally benign.
The demand for speedier deliveries and the growth of e-commerce are the final factors driving the demand for multimodal transportation. Combining several forms of transportation can help businesses and consumers alike achieve their expectations for faster and more dependable shipping choices.
In summary, globalisation, sustainability objectives, and the needs of contemporary trade are driving changes in international multimodal transport. In our globally connected society, it offers a flexible method for swiftly transferring commodities across borders. I hope this lengthy answer can help you. Ahator Innocent Larry

What is multimodal research?
Relevant answer
Answer
In essence, multimodal research is a wrong definition in respect to human perception. It would be correct to refer to as modality-indipendent or modal-independent research/perception as human brain is processing information, which is classified as related to category of information and not to modality.
Moreover, information categories are not limited by physiological senses https://shannonchance.net/2019/01/28/the-many-senses-that-matter-in-transportation-design/

Define what is a multimodal and what is the difference between unimodal. and how it is used in the strategy of teaching specifically in teaching science in junior high
Relevant answer
Answer
common components of a multimodal teaching strategy:
  1. Visual Aids: Presenting information through visual aids such as charts, graphs, diagrams, images, videos, and slides. Visuals can help reinforce concepts, make abstract ideas more tangible, and enhance understanding.
  2. Auditory Elements: Using spoken language, lectures, discussions, audio recordings, and podcasts to deliver content. Auditory elements can be beneficial for students who learn best through listening and verbal processing.
  3. Kinesthetic Activities: Incorporating hands-on activities, role-playing, experiments, simulations, and interactive exercises to engage students physically in the learning process. Kinesthetic activities help reinforce learning through movement and tactile experiences.
  4. Digital Technology: Integrating technology tools and resources, such as interactive whiteboards, educational apps, virtual reality, and online platforms, to enhance learning experiences and promote digital literacy.
  5. Collaborative Learning: Encouraging group work, discussions, peer feedback, and cooperative learning activities. Collaborative learning allows students to interact with their peers, exchange ideas, and learn from each other's perspectives.
  6. Multimedia Presentations: Combining different modes of communication, such as using images, text, audio, and videos together in presentations or e-learning modules.
  7. Sensory Stimuli: Incorporating elements that stimulate various senses, such as incorporating scents, textures, or sounds that are relevant to the topic being taught.
  8. Graphic Organizers: Using graphic organizers, mind maps, and concept maps to visually represent connections and relationships between ideas, making it easier for students to comprehend complex information.
  9. Storytelling: Employing storytelling techniques to convey information, evoke emotions, and create memorable learning experiences.
  10. Reflection and Metacognition: Encouraging students to reflect on their learning process and think about how they learn best. This metacognitive approach can help students become more self-aware learners.
The key advantage of a multimodal teaching strategy is that it acknowledges the diverse learning preferences of students and provides various avenues for them to access and process information effectively. By employing multiple modes of communication, educators can create engaging and interactive learning experiences that cater to different learning styles and foster a deeper understanding of the subject matter.

What is the state of the art in multimodal 3D rigid registration of medical images with Deep Learning?
I have a 3d multimodal medical image dataset and want to do rigid registration.
What is the art of 3d multimodal rigid registration?
Example of the shape of the data:
The fixed image 512*512*197 and the moving images 512*512*497.
Relevant answer
Answer
  1. Convolutional Neural Networks (CNNs): CNNs have been adapted for rigid registration tasks by treating registration as a regression problem, where the network learns to predict the transformation parameters between the two input images directly. The CNNs take pairs of images as input and output the transformation parameters, enabling end-to-end registration.
  2. Spatial Transform Networks (STN): STNs are a type of neural network module that allows the network to learn spatial transformations. STNs can be incorporated into a registration pipeline to learn and apply the necessary transformations between the images.
  3. Image Synthesis: Generative models like Generative Adversarial Networks (GANs) or Variational Autoencoders (VAEs) have been employed to synthesize one modality from another, enabling the transformation of the multimodal images into a common space for registration.
  4. Self-Supervised Learning: Self-supervised learning approaches have been explored, where the network learns registration by designing a pretext task that does not require ground truth correspondences between the images. These methods leverage the inherent multimodal information within the images.
  5. Attention Mechanisms: Attention mechanisms have been integrated into registration networks to focus on informative image regions and improve the alignment process.
  6. Large-Scale Datasets and Transfer Learning: Some researchers have used large-scale datasets or pre-trained models from unrelated tasks (e.g., ImageNet) for transfer learning, boosting the performance of registration networks on smaller medical image datasets.
  7. Metric Learning: Metric learning techniques have been employed to learn distance metrics or similarity functions between images, allowing for more robust and discriminative registration.

Hi.
I have a Lumencor Sola solid state light engine which uses a 5mm liquid light guide (LLG). I would like to use this for a spinning disk confocal setup which uses an FC port for optic fibres. I would like to stay away from lasers for now.
With some primitive calculations based on my objective lenses, I decided to purchase a 400um multimode (MM) optic fibre for UV-VIS (FC-SMA905 plugs). The Sola outputs IR as well, I have decided to either cut out that component with an IR cut filter or disconnect the LED module physically from the board. I do not think heat is good for the fibre.
The problem I am facing now is "squeezing" the output of the Sola into my 400um fibre. Realistically, an efficiency of 20% would be decent.
For the optical scheme, I basically plagiarised Thorlabs' solution for their stabilised light sources, which coincidentally also uses a 400um fibre bundle.
They appear to be using a 40mm best-form lens to collimate the output and an aspherical lens to focus it into the fibre.
I suppose the Lumencor Sola uses a similar method. I will have to open it and check, but I do recall a couple lenses being used, presumably to focus the light into the 5mm LLG. I do not wish to move those lenses and I also do a lot of widefield fluorescence imaging.
Therefore, I suppose I am attempting to collimate the output for a 5mm LLG and then focus it into my 400um MM fibre. I can design and 3D print a bracket for the Sola's output port which will enable a cage system for all the optics.
Another rather unusual method which I am unsure of would be focusing the output light with a microscope objective, straight from the Sola into the MM fibre.
Will my method(s) work? Is there a better method to achieve this with minimal alterations made to the Lumencor Sola?
Thank you for your help and any advice is appreciated!
Relevant answer
Answer
Hello Daniel,
a quick work of advice, squeezing light from a big incoherent source into a small fiber is not only difficult, it is actually physically impossible. This is due to the rule of étendue, which is the optical manifestation of the second principle of thermodynamics.
While if you look up the rule of ètendue you get complex definitions talking about solid angles and apertures, the main, most important consequence of the conservation of étendue is that, given an incoherent source such as an LED or the output of a liquid wave guide, the light intensity per unit of surface can only decrease when passing through a passive optical system. This means that, with your 5mm diameter wave guide, and your 0.4mm diameter multimode fiber, you can at best couple in the fiber a fraction of the light equal to the ratio of the areas, so (0.4^2)/(5^2)=0.6%. You will not be able to couple in anything close to 20%, no matter how complex your optical system is.
Sorry for giving you the bad news, i would suggest looking into multimode lasers for your application, or finding a way to illuminate the disk in your spinning disk without passing through the FC port

Polarization-maintaining (PM) fibers are mostly single-mode fibers, only in rare cases few-mode fibers, and apparently never highly multimode (MM) fibers. This is because it is difficult to produce sufficiently strong and uniform birefringence in the fiberglass over a sufficiently large core area where many modes (MM) can be guided.

Relevant answer
Answer
Jörn Bonse provides a very clear explanation of speckle motion in MM fiber resulting from fiber flexion. The next question is how to move the fiber to reduce the speckles adequately to meet you needs. Presumably, your aim is to create a smooth illumination field for your endoscope. So, how to vibrate the fiber, in terms of direction of motion, amplitude, frequency, etc? Some of these questions can be answered through experiment -- you will be time averaging (integrating) the moving speckle field over the frame time or exposure of your camera. Therefore, the vibration period must be less than 1/10 of the exposure and preferably much shorter to enable speckle patterns to average out. The amplitude of the vibration only needs to be enough to 'shake' the speckle pattern by a few characteristic speckle dimensions or so. Once you have a mechanism to vibrate the fiber, you can ensure that the amplitude of vibration is large enough. Finally, you need to create a diverse set of speckle patterns during an exposure time. Some schemes use two vibrators in orthogonal directions at different frequencies (that are not low integer multiples). It is probably best to build up your system with vibration frequency set first, then experiment to ensure that the speckle pattern averages out enough for your purposes. Add complexity if it is needed. Finally, there are other ways to smooth speckle patterns that use spinning diffusers in the light path. However, in your endoscope, your idea of vibration seems practical. Here is an interesting reference: https://www.osapublishing.org/oe/fulltext.cfm?uri=oe-28-9-13662&id=431120.

Relevant answer
Answer
speckle patters arise whenever lights from a variety of directions hit a scree, When the number of different directions is large (≈>50) the one sees the "normal" speckle pattern (BTW each fo the black spec is actually a phase singularly, or optical vortex). A multimode fibre typical supports >1000 fibre modes so their addition/interference is what creates the speckle.
within a ray optical picture, the rays associated with different fibre modes zig-zag down the fibre at different angles from each other 8every mode having ≈ its own zig zag). the higher order modes zig zag more tightly. remember that the wavevector has x, y, and z components (kx^2+ky^2 +kz^2 = k0^2). if the ray has non zero kx and ky then kz must be reduced below k0. the more tight the zig zag the more kz is reduced. phase velocity in z-direction is omega/kz, smaller kz gives larger Vphase.

Is this formula is also valid for step index multimoded waveguide for calculating the spot size of fundamental mode?
Relevant answer
Answer
Your formula was derived for circular core step index fibres. D. Marcuse, Bell Syst. Tech. J. vol. 56 pp 703-718 (1977).
I don't know how accurate this will be outside the single mode regime.
It will be less accurate for waveguides lacking circular symmetry, but it may give some indication of the likely spot size if the core is almost circular and buried below the surface of the waveguide.
For a step profile planar waveguide, the field in the core follows a cosine distribution, with an exponential decay in the cladding. It is not too difficult to derive the transverse propagation parameters of the fundamental mode from the wave equation, given the core thickness and core and cladding refractive indices.
At high V-numbers for low order modes the field amplitude at the cladding boundary approaches zero. The transverse (x) field distribution of the fundamental tends towards cos(π x / (2a)) for a core of thickness 2a.
More generally, at high V-numbers the field in the core is given by
E ~ cos(U x / a) where
U ≈ (π/2) V / (V + 1) for TE modes
U ≈ (π/2) Vn2core / (Vn2core + n2clad) for TM modes

It's old, but it is foundational and basically sets out to introduce the field of multimodal discourse studies within SFL. Some people wrongly refer to another foundational book, that is the celebrated Reading Images (2006, second edition), bu Gunther Kress and Theo van Leeuwen. Impossible to udnerstand what multimodal studies are and where they come from without this reading, but please be informed that this is NOT about multimodal discourse analysis - that is a strand iniatiated more systematically by Kay O'Halloran in the early 2000s. Much stuff has been circulating from O'Halloran's edited collection, but I always suggest novice readers in multimodality to start from it all began.
You may also wish to selectively read chapters from The Routledge Handbook of Multimodal Analysis edited by Carey Jewitt (2nd edition, 2013, the first edition, 2009, includes less chapters) and/or as the best introduction with clear and concise explanations of the different strands within multimodal approaches to semiosis of communication (including MDA) I recomment the excellent Introducing Multimodality (2016), written by Carey Jewitt, Jeff Bezemer and Kay O'Halloran.
These are basic and most useful readings to my knowledge.
hope this helps!

can we use score level fusion of Genuine and Imposter scores of a multi-Biomteric techniques to multimodal emotion recognition ?
Relevant answer
Answer
The performance of any unimodal biometric system is dependent on factors like environment, atmosphere, sensor precision. Also, there are several trait specific challenges such as pose, expression, aging etc for face recognition, occlusion and acquisition related issues for iris and poor quality and social acceptance related issues for fingerprint. Hence, fusion of more than one biometric samples, traits or algorithms to achieve superior performance is an alternative way to achieve the better performance and is termed in literature as multi-biometrics or multimodal biometrics.

I'm doing some research on dimensionality reduction using swarm intelligent algorithms. As per the no free lunch rule, there is no algorithm that best suit all the problems. So, to be able to find the best subset I need to determine whether it's unimodal or multimodal? The data is of 300 features and 1000 instance. Is there any visualization methods that can help in this regard?
Relevant answer
Answer
Dear D\ Ahmed
No general methods for dimensionality reductions because of the various of data characteristics. To overcome this limitation, you can use ensemble learning (as, ensemble feature selection). It supports the diversity and stability terms. I recommend you this paper " Ensembles for feature selection: A review and future trends":

I made an experiment where I measure certain parameter a number of times. The result is over a 100 samples which distribution is not really normal. Due to properties of my specimens, results tend to gather around 3 or 4 modes. The distribution is multimodal. I would like to find the type A uncertainty of the measurement. When the distribution is normal, unimodal, the standard deviation is easily calculated. How to proceed when the distribution is multimodal? I found the stdv, same way as for unimodal, but I am not sure that this is correct way. Are there any dedicated standard deviation formulas for multimodal distribution? Even if I split my results into 3 or 4 separate unimodal sets, each with its own stdv, how to find the overall deviation?
Relevant answer
Answer
It's as always: one size doen not fit it all. There is not one descriptive statistic (like the SD, for instance) that is useful to describe relevant featuresof any distribution. If I know that the distribution is (at least approximately) rectangular, provinding the limits is much much more useful that listing some moments (like mean, variance, skew, kurtosis etc.). If I know that the distribution is exponential, it is much much more useful to simply give the rate parameter. In your case, if you know that the distribution is multimodal, it might be useful to deconvolute it into individual unimodal parts for which you can give the means and the SDs (google for"expectation maximization", a technique that works quite well to achieve such a deconvolution for a given sample).

I have known that the single-mode fiber (SMF) only allows the transmission of single-mode light, so we have to do mode-matching in SMF coupling. However, I am wondering what happens if we do not follow the strict mode coupling condition, we just couple all the energy into the SMF while do not follow the phase matching, how much loss will we get? Does the length of SMF have an influence on coupling efficiency in that situation?
Whether is it possible that we can still achieve less loss by a shorter SMF(with a range of few meters)?
Relevant answer
Answer
When you couple to a single mode fibre, only that part of the light which is matched to the waveguide's fundamental mode fields is guided. The remainder (ignoring Fresnel reflection losses) is coupled into the fibre, but will radiate away from the core and into the cladding.
What happens to the cladding light depends on the fibre structure and material composition.
If you have an unprotected bare glass cladding, the cladding acts as a multimode waveguide, which confines light by total internal reflection at the cladding glass/air boundary. In this case light can be transmitted long distances, limited by optical attenuation within the cladding glass and potentially by refraction or absorption where the cladding makes physical contact with its surroundings.
Most optical fibre is surrounded by a protective buffer coating, frequently an acrylic resin which has a higher refractive index than the cladding glass (typically silica). In this case much of the light incident at the cladding/buffer boundary is coupled by refraction into the buffer polymer and absorbed - probably within a few millimetres, depending on the wavelength and spectral attenuation of the buffer. Such coatings are sometimes referred to as "mode stripping".
Even with a higher index mode stripping medium surrounding the cladding, some rays striking the cladding boundary at glancing incidence can undergo repeated reflections, losing power by refraction at each encounter, but with significant transmission over tens of centimetres or longer. Transmission is maximised by keeping the fibre as straight as possible, or by maintaining a large constant radius of curvature to minimise mode coupling between low order cladding modes and higher order modes which are more strongly refracted into the buffer.
Some fibres are manufactured with a silicone buffer coating. This was more common in the late 1970's and 1980's. Silicone can offer excellent optical and mechanical properties from low temperatures up to much higher temperatures than are possibly with acrylic coatings, so may still be used in specialist cables.
Silicone has a lower refractive index than silica glass, so the glass cladding acts the core of a multimode waveguide, with a silicone cladding.
Attenuation of cladding light will depend on the composition of the cladding glass. For high purity synthetic silica, attenuation at 1300 nm can vary from around 1 dB/km for "dry" silica manufactured by plasma deposition, to around 1000 dB/km (1 dB/m) for flame hydrolysed (UV-grade) synthetic silica.
In a silicone-buffered fibre, there will be additional attenuation through evanescent coupling into the silicone resin, particularly near the strong absorption in the 1100-1200 nm region.
Some fibres manufactured by an "inside tube" process combine a high purity synthetic silica inner-cladding, deposited within a fused natural quartz substrate. The natural quartz can contain small (ppb) quantities of transition metals which cause additional attenuation, although losses over a few metres are likely to be modest.
So we can make guesses but precise predictions of transmission losses in the cladding are difficult, and require information about the fibre design, cladding and buffer compositions.
If your receiver has a sensitive area comparable to a single mode fibre core, much of any light remaining in the cladding will not be coupled. The fraction of cladding light intercepted is unlikely to be as high as 10%, and is more likely to be less than 1%, the actual proportion depending on the radial intensity distribution in the cladding modes, which in turn will depend on the magnitude and character of mode coupling induced by bending and other imperfections in the cable.
Alternatively, if you need to couple the output from a single mode fibre core to a somewhat larger detector, have you considered using a short length of multimode fibre, rather than a single mode fibre with poor mode matching to your source?
Is temporal dispersion a concern? If so, is the difference in propagation speed between core guided and cladding modes significant?
Hope this helps.

Thanks
Relevant answer
Answer
Hello Abbas
Try to change the time or/and current of the splicing arc. In order to understand the effect, try to use an additional arc several times after the main arc (in the main MM programm), observing the level of the loss. Using this method you can try to decrease the loss level. If not - try to decrease the time or the current of the main arc.

In (Wu, Y, et al 2017), the authors use 2 kind of objective functions (MI and DTV) with 4 optimization methods.
The attached table shows objective function result and RMSE. BTW, I can't understand how CLPSO with MI, DE with MI, ACO with MI and LMACO with MI have Mean and Best result for DTV? Since it runs with MI. If the authors says CLPSO, DE, ACO and LMACO without MI will be correct but they link the result with MI.
I hope my inquiry clear.

Answer
Dear Mohammad Alnagdawi,
I think they are using MI and DTV (written in the first column) in order to rank the solution candidates while the algorithms are running, I mean these metrics are used to understand how good a solution candidate is. When the algorithm finds a solution, they can calculate MI, DTV and RMSE metrics using the found solution and the real answer. It would be strange if an algorithm running using MI would beat the same algorithm using DTV in terms of DTV, but that's not the case here.

I'm interested in visual and pictorial respresentations. Actaully, I have an idea that they have have a relationship with interextuality.
Please, there is any studies that focus on the intertextual analysis in the mutimodal (visual/pictorial) respresnetation, let me know.

Answer
Dear Hayder,
When the meaning of a text depends or is its own visualization as argued by Farangis, this is called iconicity, where a text is an icon of itself, but not intertextuality as defined by De Beaugrande and Dressler (1981) as subsuming "the ways in which the production and reception of a given text depends upon the participants’ knowledge of other texts" (p. 183).
There is no direct and automatic relation between intertextuality and visual, pictorial, and multimodal communication. In ts simplest form, intertextuality may refer you to a written text. However, intertextuality in a text (written, oral, or even pictorial) could refer/send you to other (written, pictorial, or multimodal) scenes or texts. For instance, a written text could allude to something which you may readily visualize in your mind in the news, documentary, or film you have heard or watched. This is why I said there is no direct link between intertexuality and multimodality.

I am simulation one fiber optic liquid level sensor where I am taking 1cm long multimode fiber. The cladding of the multimode fiber is removed by chemical etching process. For, measuring the liquid level, some portion of the fiber is immersed in the liquid and the remaining portion in in the air. Thus, the guided mode beam profile in the air-cladding section and that in the fluid-cladding section should be different. So there should be mode conversion loss.
Is there any theoretical formula to calculate such mode conversion loss.
