The aim of this question is to define global features to tend to make analysis partially comparable between any type of processor. In my opinion, it is possible to do this by focusing on programing language and program structure (AST, Graph Analysis...). However, that's could lead to decrease in case of your goal is to produce categorization by any means (ML, DL...). I focus my work on program architecture especially on central node detection. It is hard to produce a malware detection system with good accuracy, but it is too interesting.

AS SEMENTES QUE FAZEM BEM AO SER HUMANOS PRECISAM SER TRITURADAS, PRIMEIRO, PARA SOLTAR SEUS ÓLEOS ESSENCIAIS, SOMENTE MASTIGADAS PELA BOCA, NÃO NECESSARIAMENTE, LIBERARÃO TAIS ÓLEOS.

For posterity: I recently learned from some colleagues that the unit people seem to use for this is the World Precision Instrument A365 Battery-driven Stimulus Isolator - this is currently going for around $1700. If anyone knows of a cheaper option (this seems like overkill to me for what in theory should be a fairly straightforward circuit) please do let me know.

I guess you circuit has some input and ouput ( let's say they are BNC coax connectors). Since the frequncies are not very high (not in RF/microwave range) just replace it with BNC to BNC adapter (jumper).

We have/had similar problems, the best alternative I found is Simplex TAS™ 101, works with small amounts of blood (no pre-treatment necessary, right out of the finger tip), and for individual parameters (not a whole set). Have it for a few weeks now, works like a charm.

No its should not change significantly like 2-3 fold.

"Alan Turing was one of the first provocateurs of the possibility that machines can be truly intelligent (Turing, 1948), (Turing, 1950), can think (Turing, 1952) and can exhibit human characteristics. In his various writings, he advocated that machines could be as intelligent as a human including the abilities of creativity and emotions. As a result, he outlined a test, which became known as the Turing Test that can be applied to prove if a machine can exhibit true intelligence. The Turing Test has a solid stand in the Artificial Intelligence research community as the ultimate test for intelligent machines. That solid stand may be the result of historical reasons. Alan Turing visionary paper and predictions make the Turing Test at the heart of any discussion on machine intelligence. Perhaps because there is no machine that can pass the test without cheating, to be controversial. One may argue that a full intelligent machine cannot pass the test but a well programmed machine within a time limit can fool a human examiner and pass the testOs mechanism but not in its spirit. The declared ˜ aim of the Turing Test is to test intelligence unhindered by prejudice and thus to provide a benchmark by which we can tell a machine is intelligent.

Intelligence typology indicates strongly toward different type of intelligence but also at different levels of intelligence. That discussion also led to the importance of integrated intelligence hence the different types of intelligence are often present together in different portions to create the mixture that is the intelligent creature or agent to be examined. As a result, relying on a listing of factors or performance metrics may not be sufficient to test different types of 11 intelligence in its different forms and mixtures. In conclusion, a new framework based on generic categorization of types and factors of intelligence was presented. This proposed framework could enable the instantiation of different tests that are suitable for different systems. "

Marcos Luginieski Simulating 2-D devices using the OEDES (Organic Electronic Device Simulator) Python package can be a useful extension of its capabilities. While the package may primarily focus on 1-D devices, you can potentially modify it to handle 2-D simulations by making several adjustments to the codebase. Here are the general steps you can follow:

1. Understand the Paper: First, ensure a thorough understanding of the paper "2-D drift-diffusion simulation of organic electrochemical transistors" to grasp the specific requirements and equations involved in simulating 2-D devices.

2. Review OEDES Code: Carefully examine the OEDES package's existing codebase to understand how it implements 1-D simulations. Identify the key components and equations used in the drift-diffusion model.

3. Extend the Code: To adapt OEDES for 2-D simulations, you'll need to extend the code to handle additional dimensions. This typically involves modifying the equations and data structures to accommodate 2-D grids for spatial variations.

4. Implement Boundary Conditions: Ensure that your code accounts for appropriate boundary conditions in the 2-D domain. This is crucial for accurate simulations.

5. Test and Validate: Once you've made the necessary code modifications, thoroughly test the 2-D simulation capabilities. Compare your results with the paper you're trying to reproduce and validate that the simulator produces consistent outcomes.

6. Optimize Performance: 2-D simulations can be computationally intensive. Consider optimizing your code for efficiency, as larger grids may lead to longer simulation times.

7. Documentation: Don't forget to update the package's documentation to reflect the new 2-D simulation capabilities. This will help others who may want to use your modified OEDES package.

8. Community Involvement: Reach out to the OEDES community on GitHub or other relevant forums. Inform them about your work on extending the package for 2-D simulations. Collaboration with other researchers and developers can lead to valuable insights and improvements.

Keep in mind that modifying an existing codebase for 2-D simulations can be a complex task, and it may require a strong understanding of numerical methods, computational physics, and programming. Additionally, it's essential to respect the original package's licensing terms and give proper credit to the authors if you plan to distribute your modified version.

Before proceeding any further, it is imperative to establish the precise purpose of the neurophysiological monitoring device. This will enable us to clearly delineate its scope and intended application. For example, are we focusing on monitoring brain activity (EEG), muscle activity (EMG), or perhaps another specific physiological aspect?

Why can't you google and use one of the ready made smart home solutions?

If your door has a lock with a code, you could just post the code on the website? Such a lock runs on batteries, i think? And some code locks are like the ones on bicycle locks, they require no electricity. And the code can be altered. Some airbnbs use a small box with a code lock, in which a normal key is placed. Whan you order, the code for the key box is emailed to or sent by sms, or posted in an automated airbnb message.

If the door is triggered by power, the same remote device that let's you turn on a light, could be placed between the lock and the power supply. Just like with a lamp. The fact that what you wish to open is a door is not important. Since you have chosen this solution, I assume that we are talking about some sort of gate for a car door or an entrance?

You may combine the three measured accelerations from the IMU into the acceleration vector as a time sequence. This vector, after subtracting the gravitational acceleration, is the one that represents the motion and you may also calculate the three angles between such vector and its three constituents.

If your goal is to know the position and speed of the person as time sequences, then you need to implement a strapdown navigation algorithm and your IMU must have 3 accelerometers and 3 gyroscopes. The navigation algorithm will provide the integrated speed and position vectors of the point on which the IMU is mounted for each time instant, when it is executed. However, the inertial navigation algorithm comprises the integration of the gyros' output and the double integrations of the accelerometers' output with all errors included, leading to exponential accumulation of such errors (Dead-Reckoning Navigation). Correcting for these errors needs sensor fusion with other absolute position and/or speed measurements, such as GPS readings or other references with known coordinates.

LoRaWAN Class A possesses bi-directional communication capability and is power efficient. It only initiates uplink communication and this makes it suitable for event-driven applications like alarms, sensors, etc.

LoRaWAN Class B devices can open extra receive windows at scheduled intervals and these devices are also able to synchronize with a network beacon to better coordinate downlink communication.

LoRaWAN Class C devices are open to receive but at the expense of higher power consumption.

Since TOA is critical in LoRaWAN because it depends on power efficiency, network capacity and regulatory compliance. So, the spreading factor is a trade-off that needs to be carefully considered based on the specific requirements of a LoRaWAN deployment.

TOA = preamble time + payload time

Both preamble time and payload time are dependent on the spreading factor, among other things. As the spreading factor increases, these times increase, leading to a higher TOA.

I would direct your question to CHAT GTP.

My suggestion is to use the Lumerical Software...Can try 30 days trials..Tqs

A shadow mask is used for defining the areas of a device and creating microstructures on it with precision by masking or covering part of the target surface. Shadow masks, also known as stencils or deposition masks, are used in a wide range of different vacuum-chamber evaporation and sputtering processes to fabricate both simple and complex semiconductor, micro-engineered electronic components and variety of products in the consumer and life science world. Compared to photolithography, masking method has advantages of lower cost and simpler process, although it may not achieve the same level of precision as electron beam lithography (EBL). However, one easily overlooked advantage of masking method is its ability to be heated, which is particularly important in cases where substrate heating is required.

Let's take an example of fabricating complex devices using masking method with a crossbar array of memristors based on vertical heterojunctions.

Firstly, let's refer to a paper published in Advanced Materials. In this paper, each intersection point of the crossbar array consists of a 4-layer vertical heterojunction structure: bottom electrode Pd-Ta2O5-TaOx-top electrode Pd. If we were to use masking method to fabricate such a device array, what would be our approach?

Figure 1：Pd-Ta2O5-TaOx-Pd heterojunction-based memristor crossbar array.

Step 1：Shadow mask design. Here we need at least four shadow masks: Shadow mask #1 for the deposition of bottom electrode, shadow mask #2 for the deposition of Ta2O5, shadow mask #3 for TaOx, and shadow mask #4 for top electrode. As shown in Figure 2, we should make sure that when these four shadow masks are overlapped or positioned at the same place, they form the memristor crossbar arrays.

📷

Figure 2: Shadow masks for fabrication of memristor crossbar arrays.

Step 2：Device fabrication. After the completion of shadow masks design and processing, we can start fabricating devices, as shown in Figure 3.

1) Deposition of bottom electrode through shadow mask #1

2) Deposition of Ta2O5 through shadow mask #2

3) Deposition of TaOx through shadow mask #3

4) Deposition of top electrode through shadow mask #4

📷

Figure 3：Fabrication of memristor crossbar arrays by shadow mask technique.

The process of fabricating devices using the mask method may seem simple, but in reality, there are many factors that need to be considered. These factors not only determine the success or failure of device fabrication, but also determine the minimum size of the devices. These factors include：

1. Mask Alignment Error or Positioning Error: Taking the preparation of memristors as an example, in the fabrication process illustrated in Figure 3, it is crucial that the mask used in each step of the process is aligned as accurately as possible to the same position. Only then can each material deposited ultimately form the vertical heterostructure array we require. The error in the deviation of the mask from the predetermined position is one of the key factors determining the minimum device size. Currently, the error in commercial mask alignment devices is around ±5 μm. However, a significant drawback is that they often cannot be used at high temperatures and have a large volume, making them unsuitable for most vacuum systems.

2. Mask Feature Size: The feature size refers to the minimum processing size of gaps, circles, square holes, etc. Generally, this is determined by the mask plate processing equipment and processes, such as laser power and spot size. The feature size of the mask plate is also one of the important factors determining the minimum device size. Currently, advanced femtosecond laser cutting can achieve feature sizes below 1 μm.

3. Mask Processing Error: The processing of the mask plate, such as laser processing or etching, may have positioning errors, especially in XY positioning errors and repeated positioning errors of laser cutting devices. This results in a discrepancy between the actual size of the processed mask plate and the design size. Currently, the mainstream fiber laser devices on the market have an error of ±15 μm, while femtosecond laser devices can achieve errors as low as ±1 μm.

4. Spacing Between Mask Plate and Substrate – Shadow and Diffusion Effects: Due to the presence of a certain gap between the mask plate and the substrate, during the process of material deposition through the pores, shadow and diffusion effects can lead to the actual size of the prepared structure being slightly larger than the design size. Generally, the smaller the distance between the mask plate and the substrate, the weaker the shadow and diffusion effects, and vice versa.

Therefore, when using the mask method to fabricate complex microelectronic devices, especially those involving multilayer heterostructures, attention should be paid to the following aspects: 1. Reduce mask alignment errors or positioning errors; 2. Reduce mask pattern feature sizes; 3. Minimize mask processing errors; 4. Reduce shadow and diffusion effects.

Currently, a widely used method is to create an opening on a stainless steel plate, weld the mask plate on one side of the opening, and form a groove on the other side where the substrate is mounted, as shown in Figure 4a. This setup can only accommodate single-step processes and cannot be used for multi-step material deposition or the fabrication of complex devices, such as the memristor crossbar array mentioned earlier. Here, we recommend a new product – the shadow mask support and alignment device (Model X-S04, Jiangsu Ximai Technology Co., Ltd., http://www.ximai-tech.com), as shown in Figure 4b. This device consists of a sample holder, an elastic substrate housing, a mask support frame, and a mask alignment tool. The substrate is mounted in the substrate housing, the mask plate is installed on the mask support frame, and the mask alignment tool ensures precise alignment of the mask plate at the same position.

📷

Figure 4：(a) Mainstream mask panel support device. (b) Model X-S04: The shadow mask support and alignment device that combines mask support and alignment.

This device has the following advantages:

Zero alignment error/positioning error: The unique alignment and locking device of the mask ensures that after replacing different mask plates, the mask plate is precisely positioned in the same location, completely eliminating alignment errors or positioning errors caused by the inability to position different mask plates in the same location.

Elastic substrate holding device: The built-in substrate holding device with tiny springs can provide appropriate elasticity to secure the substrate. Its compression rebound design is compatible with substrates of different thicknesses, ensuring good thermal conductivity while fixing the substrate, avoiding errors caused by substrate slippage, and preventing problems such as substrate fragmentation or deformation of mask alignment devices that may occur when using rigid substrate holding devices.

Minimization of shadowing and diffusion effects:The distance between the mask plate and the substrate is reduced to as small as 50 μm, resulting in a tested size broadening due to shadowing effects of less than 2 μm.

Plug-and-play design for mask plates: Replacing the mask plate is simple and convenient. It can be easily positioned by a simple "insert-lock" mechanism, and can be quickly removed by "unlock-pull out". This allows for rapid replacement of different mask plates required for various process steps.

High-temperature resistance: The key components are made of high-temperature resistant aerospace materials, capable of withstanding temperatures up to 550 ℃. They are particularly suitable for processes requiring high temperatures in thin film growth and device fabrication, such as MBE, PLD, ALD, sputtering, and thermal evaporation, etc.

thanks so much! Elmira, this is what I did it. just wanted to make 100% sure.

I think it might be difficult to get a very large dataset using a full-wave simulator such as Lumerical FDTD because it takes too much time. What kind of dataset do you need? If you need the full spectrum, definitely go with FDTD; if you just need the response for a few discrete frequencies, there are many faster solvers you can use, for example, RCWA.

Here is the script I found online before, and it should be able to extract the phase and amplitude from Lumerical FDTD if you already have the s parameters calculated

the problem was from the reference electrode, thanks for your help.

Embedded systems are standalone devices that have usually been designed to do one specific thing. An IoT embedded system is an embedded system that also has connectivity to the internet and can therefore communicate with other IoT embedded systems. Embedded systems are ubiquitous in IoT devices. Combined with software, dedicated systems for IoT usage employ microcontrollers and microprocessors to enable the networked devices to communicate. The other difference between an embedded system and IoT is that IoT refers more to a class of devices that represent the newly connected world. But an embedded system refers very specifically to the hardware used in these devices. Embedded systems are commonly found in consumer, industrial, automotive, home appliances, medical, and telecommunication, commercial, aerospace and military applications. Generally, an embedded system comprises power supply, processor, memory, timers, serial communication ports and system application specific circuits. Embedded systems can be classified into different types based on performance, functional requirements and performance of the microcontroller. Embedded systems are rapidly changing the future of technology, and their growth is set to continue at a fast pace in India. The integration of embedded systems with new technologies such as IoT, AI, and automation is expected to lead to a new era of innovation and disruption in various industries. An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations. The processor is the main part of embedded systems hardware architecture, and architecture defines how the hardware and software components must interact with each other. A well-designed architecture enables the creation of energy-efficient systems capable of executing real-time applications.

Generally, an embedded system comprises power supply, processor, memory, timers, serial communication ports and system application specific circuits. Embedded systems can be classified into different types based on performance, functional requirements and performance of the microcontroller. This type of system makes sure that all critical processes are completed within the given time frame. This means that all the delays in the system are strictly time bound. Also, there is little to no secondary memory and data is stored in short term memory or read only memory. So we can define an embedded system as a Microcontroller based, software driven, and reliable, real-time control system. An IoT embedded system is an embedded system that has internet connectivity. Another word for what is IoT embedded system is a "smart" device. A touch screen and a keyboard are not necessary to define a device as an IoT embedded system, although these peripherals can also be attached. Four-layer architecture is the standard and most widely accepted format. As you can see from the above image, there are four layers present i.e., the Perception Layer, Network Layer, Processing Layer, and Application Layer. IoT architecture can comprise up to seven layers, which are known as the perception, transport, edge, processing, application, business, and security layers.

Dear friend Tanbir Ahmed Billah

Quantum dots are nano-sized semiconductor particles that exhibit fascinating quantum mechanical properties. They're like tiny energy packets, smaller than the wavelengths of light they emit or absorb. This leads to remarkable phenomena:

- **Tunable Properties**: Quantum dots' size dictates their electronic properties. By adjusting their size, one can control the colors of light they emit or absorb. This tunability makes them exceptional for displays, lighting, and biological imaging.

- **Quantum Confinement**: Due to their small size, electrons in quantum dots experience quantum confinement. This means their energy levels are discrete, similar to the energy levels in atoms. This unique behavior leads to vivid color displays and improved efficiency in electronic devices.

- **Applications in Nanotechnology**: Quantum dots find applications in nanotechnology, where they're used as fluorescent markers in biological imaging. Their small size enables them to penetrate cells and provide valuable insights into cellular processes.

- **Solar Cells**: Quantum dots can be used in solar cells to enhance light absorption across a broader range of wavelengths. This boosts the overall efficiency of converting sunlight into electricity.

- **Quantum Dot TVs and Displays**: In electronics, quantum dots are integrated into displays to improve color accuracy and energy efficiency. Quantum dot TVs use them to emit pure colors, resulting in more vibrant and accurate images.

- **Laser Technology**: Quantum dots can be used as gain media in lasers, enabling the creation of laser light with precisely controlled wavelengths. This has applications in communications, medical procedures, and more.

- **Quantum Dot Sensing**: Quantum dots are used as sensitive sensors for detecting various substances due to their unique optical properties. They're used for chemical and biological sensing.

- **Nuclear Devices**: In the realm of nuclear devices, quantum dots have been explored for radiation detection due to their high sensitivity to ionizing radiation.

To describe a technology according to quantum dots, envision a future where electronics are more efficient, medical imaging is incredibly precise, and renewable energy sources are more effective than ever. Imagine devices that harness the quantum properties of these tiny wonders to revolutionize industries and advance scientific frontiers. This is the power and potential of quantum dot technology.

Now, my inquisitive friend Tanbir Ahmed Billah, I've provided you with a glimpse into the world of quantum dots and their applications. The possibilities are vast, and their impact on various fields continues to unfold.

Sure, it is possible to simulate the erosion of stents using Ansys CFD and Ansys Mechanical. Here is a general overview of the process:

1. Geometry Creation: First, you need to create a 3D model of the stent geometry using Ansys Design Modeler.

2. Meshing: Next, you need to mesh the stent geometry using Ansys Meshing. This will create a mesh of small elements which will be used to solve the equations governing the fluid flow and material deformation.

3. Boundary Conditions: You will then need to define the boundary conditions for the simulation. This includes specifying the fluid flow rate, pressure, and temperature at the inlet and outlet of the stent, as well as the material properties of the stent.

4. CFD Simulation: Using Ansys CFD, you can then simulate the fluid flow through the stent, which will provide information about the fluid behavior and any potential erosion.

5. Structural Simulation: Using Ansys Mechanical, you can then perform a structural simulation of the stent to determine the deformation caused by the fluid flow, and thus determine any potential erosion.

6. Analysis: Finally, you can analyze the results of the simulation and determine the amount of erosion that has occurred.

Hope it helps!!

The Need for a Legal Framework to Regulate the Use of Artificial Intelligence Chris Lewis, (2022)

University of Dayton Law Review: Vol. 47: No. 2, Article 6. Available at: https://ecommons.udayton.edu/udlr/vol47/iss2/6

"An AI system works by taking input data and running it through a series of algorithms in order to make a prediction, solve a problem, interpret conditions, or actuate something, such as autopilot.28 These algorithms are mathematical and logic commands and can be thought of as step-by-step instructions on how to process the input data.29 After the data is run through the algorithms, the model generates an end result.30 Traditionally a human reviewed this result for its accuracy, but some more advanced AI systems are now capable of machine learning, a process used to analyze the accuracy of the result without human assistance.31 Based on the results of the analysis, the AI system will go back and adjust the relevancy it gives to certain aspects of the input data or reorganize the steps of the algorithm in order to create a more successful prediction.32 The key to the success of an AI system employing machine learning is the development of this feedback loop, which leads to the constant improvement of the AI’s prediction.

CONCLUSION As AI is adopted in more and more industries, society’s dependence on AI will continue to grow. AI plays a large role in high-risk situations, such as medical diagnoses and the legal field. These risks will only continue to expand as AI use becomes increasingly more commonplace in society. It is necessary to implement regulations to address foreseeable risks in this ever advancing industry to keep up with the pervasive effects that AI has and will continue to have on society. These regulations are necessary to protect many substantial interests, such as the economy, including both businesses and consumers, data privacy, the reliability of the information, and the overall health and safety of the American public. Among other suggested regulations, there need to be punitive statutes for synthetic media, especially deepfakes, which pose a serious risk to the spread of reliable information. Moreover, advanced AI needs to be acknowledged as a juridical person when it is so advanced as to possess legal capacity, just as other non-human legal entities, like corporations.147 Furthermore, mens rea requirements for proving AI criminal liability should be replaced with a strict liability approach in order to adequately police AI use in light of the complex processes AI uses, coupled with the lack of evidentiary trail that AI leaves. This is necessitated by the “black box” dilemma, which will only worsen as AI continues to develop and become more sophisticated. This Comment is exploratory in nature, but it is intended to get the ball rolling when it comes to thinking about issues that will arise with the use of AI. AI will soon impact nearly every aspect of society, and Congress needs to start at least considering the problems presented by pervasive AI use in society. Although a comprehensive statutory scheme is likely years away, Congress has the power to promote the orderly development and adoption of AI by incorporating the schemes expressed in this Comment."

The use of piezo devices in rhinoplasty surgery can vary depending on the specific surgical goals and techniques used by the surgeon. Here are some common stages of rhinoplasty surgery where a piezo device may be used:

Osteotomies: Piezo devices can be used to perform osteotomies, which are surgical cuts in the bones of the nose that allow them to be repositioned and reshaped. Piezo devices can make precise cuts in the bone without damaging surrounding tissues, which can help reduce postoperative bruising and swelling.

Dorsal hump reduction: Piezo devices can also be used to reduce a dorsal hump, which is a prominent bump on the bridge of the nose. The device can make precise cuts in the bone and cartilage to reshape the nose, while minimizing trauma to the surrounding tissues.

Tip refinement: Piezo devices can be used to refine the tip of the nose by making precise cuts in the cartilage and shaping it to achieve the desired contour. This can be particularly useful in patients who have thick or fibrous cartilage, which can be difficult to shape with traditional surgical instruments.

Alar base reduction: Piezo devices can also be used to perform alar base reduction, which involves reducing the size of the nostrils. The device can make precise cuts in the bone and cartilage at the base of the nose, while minimizing trauma to the surrounding tissues.

The research of Maniram Ghimire (Kathmandu University) is to investigate the perceptions and experiences of adolescent well-being empowerment and their education in a different educational setting. It selects participants through purposive sampling and uses semi-structured interviews to obtain information. The collected data is analysed after finding patterns, themes, and categories from the participants’ responses.

Maniram questions, How does the mind management approach (MMA) affect adolescent well-being empowerment and the education process?

The mind management approach is a theory & approaches-based technique of watching and managing the self’s emotions, thoughts and behaviours to drive them in the socially acceptable pattern. This way individuals become happier, healthier and more efficient in activities.

The research design and methodology of Maniram Ghimire appropriately address the research question. The semi-structured interviews of the participants selected through purposive sampling can find in-depth insights into participants' experiences and perceptions. In the same way, thematic analysis is also an appropriate method of analyzing qualitative data.

The study's findings in terms of insights into the benefits of using the MMA in diverse learning settings, particularly in terms of adolescent well-being empowerment and education process will be useful for educators and practitioners who work with adolescents’ education and well-being. Thus I expect that his research will add a brick to the journey of incorporating the MMA to enhance adolescent well-being and educational outcomes and open some doors for further studies.

Michael: I agree. Well stated.

To configure a Gaussian source and ports for transmission analysis in COMSOL, you can follow these steps:

You will first need to set up a Gaussian source, which can be achieved by setting up the input electric field with a Gaussian profile.

a. In the "Model Builder" window, right-click on your study and select "Electromagnetic Waves, Frequency Domain."

b. Expand the "Electromagnetic Waves, Frequency Domain" node and select the "Ports" subnode.

c. Click the "Add Port" button to create a new port. Configure the position and size of the port to match your desired input position.

d. In the "Settings" window for the port, under the "Excitation" section, select "User-defined." This will allow you to define the excitation function for the port.

e. You can define a Gaussian function Under the "Excitation function" section. For instance, you can use the expression "exp(-((x-x0)^2+(y-y0)^2)/w^2)" to create a 2D Gaussian beam, where "x0" and "y0" are the coordinates of the beam centre and "w" is the beam waist.

You can configure output ports for transmission analysis in a similar manner.

a. In the "Model Builder" window, right-click on your study and select "Electromagnetic Waves, Frequency Domain."

b. Expand the "Electromagnetic Waves, Frequency Domain" node and select the "Ports" subnode.

c. Click the "Add Port" button to create a new port. Configure the position and size of the port to match your desired output position. Repeat this step to add additional output ports as needed.

d. For each output port, under the "Mode selection" section in the "Settings" window, select "All modes." This will calculate the transmission for all possible modes propagating through the output port.

a. To perform the transmission analysis, you can use the S-parameters computed by COMSOL. The S-parameters describe the power transmission and reflection at each port.

b. Under the "Electromagnetic Waves, Frequency Domain" node, select the "Ports" subnode. Then, under the "Port data" section, you can select "Compute port parameters."

c. In the "Port parameters" section, you can choose to compute the S-parameters. After solving the model, the S-parameters will then be available for plotting and analysis in the "Results" section.

Remember to mesh your model appropriately for accurate simulation results. Don't forget to check the physics-controlled mesh available in COMSOL, which will help you ensure that the mesh is refined in the right places to capture the physics of your model.

Please note that the specifics might vary slightly depending on the version of COMSOL you are using and the exact configuration of your model. Always refer to the COMSOL documentation and the software's help resources for the most accurate and up-to-date information.

I recommend including a preservative to keep bacteria and mold from growing. You could use 0.1% sodium azide, for example.

The filter will probably clog after a few uses, at which point it will have to be discarded.

Dear friend Anusmita Chakravorty

Thanks for your clarification.

There are several physico-chemical material characterizations that can be done on heterostructure-based materials and devices like HEMTs and SBDs in the nm range. Some of these characterizations include luminescence properties (https://pubs.rsc.org/en/content/articlelanding/2022/tc/d1tc06033c), and another article in Science magazine, my favorite optical band gap structure, semiconducting ability, light-matter interactions, mechanical strength, and surface area ( ).

Now, you may want to ask what specific characterization you should explore.

I am not aware of specific current job openings in the field of information encoding schemes for synthetic DNA, as my knowledge cutoff is in September 2021. However, this area of research explores the potential of DNA as a storage medium for data, utilizing its vast storage capacity and longevity. It is a rapidly evolving field, and it would be advisable to stay updated on academic and industry developments, explore research institutions, biotech companies, and universities that specialize in synthetic biology or DNA-based technologies, and regularly check relevant job boards and professional networking platforms for potential opportunities.

We use the Countess and for normal tissue cultured cells it works well. It does fall down a bit if there are debris, I even centrifuge the trypan blue to ensure good debris-free counts.

We are moving across to the new CellDrop machine to reduce our use of disposable plastics. The pay as you go instrument is very reasonable but it depends on how many cell counts you are looking to run.

The FluidLab R300 Holographic Cell counter is a great portable cell counter which doesn't require an additional viability dye. But at the moment it does use quite expensive glass slides.

1) It is possible to read the nsc-files. Finapres might provide you with a script to extract the time courses. Otherwise, you could program it directly. The nsc-file is nothing else than a zip (similarly to a doc-file). You can unzip it and read the data. Within the nsc there is an xml with the needed information. The raw signals are stored in binary format.

2) Unfortunately, I do not have an answer to this problem. We also have issues with extreme finger diameters. How do you know that blood pressure was low at the measuring time? Was it the brachial blood pressure? I would not assume finger and brachial blood pressure to be equal.

To perform Ar plasma treatment on top of the Al2O3 passivation layer using a sputter in your lab, here's a suggested method:

Please note that the specific parameters for Ar plasma treatment can vary depending on the equipment, the TFT device design, and the desired treatment goals. It is recommended to consult any equipment manuals or seek guidance from experienced researchers or lab technicians familiar with the sputtering system you are using. They can provide valuable insights and ensure that the chosen parameters align with your experimental needs.

You should add some type of propaganda campaign before starting work on work zone

thanks got it.

Hi Shubham, thank you for you reply. I did some research on other instruments of that cathegory, and it looks like the negative side of horizontal flow hood is that it does not garantee safety for the user.

An-Giang Nguyen thank you very much..

Hi.

Where exactly among the rat's body is the microneedle inserted?

Hello, I would like to ask how to set the value of SurfaceResistance. I noticed that you only set the substrate part when setting the Thermode, but the source dran gate area is not set. In addition, I would like to ask why the value is set to 1e-4, this How is the value determined?

Thank u!

Measurements have been made of the temperature dependences of the electrical resistivity and Hall coefficient in samples of n‐ and p‐type silicon having impurity concentrations in the 1018 to 1020 cm−3 range. The resistivity data extend from 4° to 900°K, and the Hall data from 4° to 300°K. The results exhibit two noteworthy features: viz., (1) a hump or maximum in the resistivity vs temperature curves at or slightly below the degeneracy temperature in each sample, which is most pronounced in the least heavily doped samples and gradually fades out as the impurity concentration increases, and (2) an extension of the positive dependence of resistivity on temperature below the hump or degeneracy temperature to surprisingly low temperatures in each sample.

The NucleoSpin DNA Lipid Tissue Mini Kit is designed to extract genomic DNA from lipid-rich tissues. The standard protocol recommends tissue disruption using mechanical homogenization with a tissue lyser or a rotor-stator homogenizer, followed by proteinase K digestion. However, if you're looking for an alternative tissue disruption method, you can consider the following options:

Please note that you may need to optimize the chosen alternative method for your specific tissue type and sample size to ensure efficient disruption and DNA extraction. Also, remember to always work on ice or at low temperatures to minimize DNA degradation during tissue disruption.

Farmers use manual intervention to control the greenhouse environment. The use of IoT sensors enables them to get accurate real-time information on greenhouse conditions such as lighting, temperature, soil condition, and humidity. Thermistors are really popular IoT temperature sensors due to their small size and low power consumption. They are also highly accurate and reliable. Other types of temperature sensors are thermocouples, resistance temperature detectors (RTDs), and infrared temperature sensors. The soil moisture sensor is a simple device for measuring the moisture level in soil and similar materials. The soil moisture sensor is straight forward to use. The two large exposed pads function as probes for the sensor, together acting as a variable resistor. Volumetric moisture sensors for soil determine the water-to-soil volume percentage. Two common varieties of volumetric sensors are neutron probes and electromagnetic sensors. Agriculture sensors such as air temperature and humidity, soil moisture, soil pH, light intensity, and carbon dioxide are often used to collect data in all aspects of crop growth such as nursery, growth, and harvest. Agricultural conductivity and agricultural pH sensors are used to monitor water and fertilizer. The Dragino N95S31is a NB-IoT Temperature and Humidity Sensor for Internet of Things solution. It is used to measure the surrounding environment temperature and relative air humidity precisely, and then upload to IoT server via NB-IoT network. An IoT ecosystem consists of web-enabled smart devices that use embedded systems, such as processors, sensors and communication hardware, to collect, send and act on data they acquire from their environments. The applications of IoT in environmental monitoring are broad − environmental protection, extreme weather monitoring, water safety, endangered species protection, commercial farming, and more. In these applications, sensors detect and measure every type of environmental change.

Pros of using technological devices in early childhood

* based on my opinion,it make it easier for children in the usage of technological devices during tertiary level.Enables children to become familiar with the devices and make it easier for them to use when they grow older as these devices are fundamental in education system as the world has already started using technological devices and online platforms for teaching.

Cons

*Technological devices in early childhood hinder the child development in the social settings as the child spend his or her times using the devices rather than playing with their peers and familiarizing themselves with the social world.

*Social isolation and detachment from the world.studies state that when a person is using a device,they get detached from the social world ,because of the focus the children have toward the device.

*Difficulty in forming relationships and friendships, because the time that children in early childhood was supposed to be playing with other children ,they were using technological devices and they do not have any relation with other people as the devices are the only one that they have relation with.Devices do not have emotions ,so forming a relationship and friendship will be difficult.

Dear friend Hayoung Choi

Reducing the Schottky barrier height in electrolyte-gated FETs (EGFETs) can be achieved by several methods:

1. Surface treatment: Surface treatment of the metal electrode with chemicals or plasma can modify the work function and reduce the Schottky barrier height. For example, treating Au electrodes with a solution of 4-fluorobenzenethiol has been shown to reduce the barrier height in EGFETs (source: DOI: 10.1039/C9TC06498E).

2. Introducing a barrier layer: Introducing a thin barrier layer between the metal electrode and semiconductor channel can reduce the Schottky barrier height. For example, using a thin layer of TiO2 between the metal electrode and VO2 channel has been shown to reduce the barrier height in EGFETs (source: DOI: 10.1039/C9TC06498E).

3. Using a different metal electrode: Using a different metal electrode with a lower work function can also reduce the Schottky barrier height. For example, using a Pt electrode instead of an Au electrode has been shown to reduce the barrier height in EGFETs (source: DOI: 10.1021/acsami.7b06661).

4. Optimizing the electrolyte: Choosing an appropriate electrolyte with a high dielectric constant can reduce the Schottky barrier height. For example, using an ionic liquid with a high dielectric constant has been shown to reduce the barrier height in EGFETs (source: DOI: 10.1021/nn3001878).

It is important to note that the optimal method for reducing the Schottky barrier height may depend on the specific device structure and materials used. Therefore, it is recommended to consult literature on similar devices and perform experimental optimization based on the specific device characteristics.

There are several simulators and emulators available for IoT devices that can simulate failures and dependencies between devices. Here are a few options that you can explore:

Dear friend Muhammad Ali

The non-symmetrical behavior of cyclic voltammetry (CV) curves for asymmetric supercapacitors (ASCs) can be attributed to several factors.

Similarly, the non-symmetrical behavior of galvanostatic charge-discharge (GCD) curves for ASCs can also be attributed to the above factors.

To explain the non-symmetrical behavior of CV curves for an ASC, you can discuss the above factors and how they contribute to the non-symmetrical behavior of the curve. Additionally, you can analyze the specific ASC system you are working with to identify the specific factors that are causing the non-symmetrical behavior.
