Transition - Science topic

Thank you, mam.

Can I use the same software to study the photoluminescence transition also?

It was an interesting topic, if you come to a conclusion, please share

I would consider: power capacity , carbon footprint, land footprint, economic feasibility and resources or feedstock availability

In your "free postoptimization", have you tried playing with the convergence criteria, both for the SCF and the geometry? Eventually, that may be helpful.

A transition state which has been calculated with fewer constraints will surely find more acceptance than a constrained one.

The method you use to calculate a TS is correct, Opt=(TS,calcfc,noeigen). However, it is important to have a good approximation to the TS. You should first perform a scanning of how energy changes when methyl is deprotonated (see attached). To do that, do a scan job:

# opt=modredundant plus other keywords

.../...

.../...

B 1 2 S 10 0.10

This is only an example, replace 1 and 2 with the atom label of your molecule, S means scan type job, 10 -0.10 means ten steps with an increase of 0.10 angstroms. You need to adjust these parameters to your problem.

After the scan finishes, select the highest point and run TS optimization.

Hope this is helpful.

Best, Pablo

CASTEP, as many DFT codes, calculates the band structure and thus evaluates the difference between the last occupied state and the first un-occupied state. The establishment of selection rules to determine if a transition if forbidden or not is another step. You could plot the spin resolved bands or spin resolved DOs, for example, and obtain such information.

Anyway, if you believe this is a bug, I am confident people at CASTEP would be happy to hear your comments and eventually take action. Commenting on a general purpose research website might not be leading to a solution.

Roberto

You are very correct.

Thus any physical event, whether classical or quantum, can be expressed in PDE1 format and its solution can be presented in the format of equation 3.

Note that in the case of a spontaneous Markovian transfer event not driven by the source term S or the boundary conditions b, you must substitute S=0 and b=0 into equation 3 to obtain,

U(t)=IC. B^N. . . . . . . . .(3*)

Equation 3* is the stochastic Markov matrix equation for the eigenvalue λ =1.

Without using tables of calculated values (see links on the other questions), you can't assign these.

MNN, MMN, NNN are the description of Auger peaks, for more detail the subshells should be added, see here:

You use MNN, MMN, NNN , e.g. heavier elements are considered, the energy and width will depend on the atomic number.

The energy of transitions are tabeled, but the measured width depends also on the spectrometer.

Joy LaRusic To effectively support high school students with disabilities transitioning to post-secondary education, early and individualized planning is key. For example, starting transition discussions as early as 9th grade can help identify a student's strengths, interests, and areas where they need support. Schools can work closely with students to set specific academic and career goals while introducing them to self-advocacy skills.

Take Sarah, a student with dyslexia. Her high school transition plan includes regular meetings with a counselor to learn how to access accommodations, such as extended exam time and assistive reading technology, that she’ll need in college. Her teachers also ensure she practices using these tools so she's confident by the time she enters higher education.

Another critical practice is connecting students with mentors or peer groups who’ve successfully made the transition. For instance, universities can offer mentorship programs where current students with disabilities guide incoming freshmen through the process of applying for accommodations, navigating campus life, and managing workload.

Lastly, collaboration between high schools and colleges is crucial. High school staff should ensure that students are aware of services available at their future colleges. Colleges can facilitate this by hosting transition workshops or virtual tours that familiarize students with disability services before they even set foot on campus.

These steps build confidence and prepare students for success beyond high school, ensuring a smoother, more supported transition into the next phase of their education.

Numerical example,

The resulting statistical integration formula I = ∫ y dx for n = 7 nodes is the formula,

I = 6h/77 (6.Y1 +11.Y2 + 14.Y3+15.Y4 +14.Y5 + 11.Y6 + 6.Y7). . ..(5)

And the statistical integration formula I = ∫ y dx for 11 nodes gives:

I=10 h/ 145*[6.191+ 10.715 +13.862 +15.921 17.056+

17.4344025 + . . +. . . ] . . (6)

It is worth mentioning that the numerical results of equations 5.6 are more accurate than those obtained from the trapezoidal rule and those obtained from Sympson's rule.

Note also that the artificial method of Lagrange multipliers used for the derivation of Sympson's rules is not necessary for the derivation of equations 5,6.

This confirms that classical 3D+t spaces do not allow the generation of well-defined mathematical rules and hypotheses.

Yes... it is as the colleague above tells you. Just right-click on the graph and select unwrap to undo that jump.

Finally, here is a simple understanding of spaces:

The Laplacian theorem lives and functions in the 4D-unit space but not in the classical 3D+t space.

The theory of relativity and the speed of light c lives and functions in 4D unit space but not in classical 3D+t space.

Dear Joannis,

this is actually what is proposed. To define a rock as ultrapotassic we propose to follow the suggestion of Foley et al. (1987), i.e., K2O >3 wt% and K2O/Na2O >2, as in the scheme proposed in this thread. In addition we should consider also MgO >3 wt%, to exclude that the relatively high K2O could be simply an effect of prolonged fractionaly crystallization of K2O-poor mineral assemblage. For example, K2O-rich trachytes of the Phlegrean Fields volcano cannot be considered as ultrapotassic, because strongly fractionated melts with very low MgO.

Note that the original definitions for ultrapotassic rocks considered K2O/Na2O ratios be >3. Foley et al. (1987) reduced this ratio to 2 to include several rocks in the "ultrapotassic" family.

I did not find any word referring to "timanite" or "doiranite" in the Le Maitre (2002) book.

At the end I underline that "pyribole" is not a mineral name reccommended by IMA, so I would not quote it in the new edition of the book.

Cheers,

michele

Economic Challenges

Economic Opportunities

These points highlight the complex balance of immediate costs and long-term benefits associated with transitioning to a low-carbon economy​ (Prosci)​​ (Emerald)​.

Implementation of the process of green transformation of the economy, including the green transformation of the energy sector, i.e. mainly the development of renewable and emission-free sources of energy, is financed primarily from two types of sources, i.e. financial subsidies from the state's public finance system and within the framework of commercial green external financing implemented, among others, through green loans provided by commercial banks and green corporate bonds issued by corporations, companies, enterprises implementing pro-climate, pro-environmental and/or pro-environmental business ventures. In a situation where the said pro-climate, pro-environmental and/or pro-environmental business ventures are implemented by innovative startups that implement and develop eco-innovations and new green energy technologies then they can obtain equity financing through the subscription of shares by an investment fund that co-finances commercial, innovative green business ventures as part of its business model. What scale of financial subsidies are offered to businesses and citizens from the state's public finance system depends on whether the country's government and/or local government authorities are more or less serious about the need to implement processes of green transformation of the economy with a view to moving away from the dirty energy of burning fossil fuels in order to switch to cheaper, clean, green, renewable and emission-free sources of energy, and increasing the scale of implementation of sustainable development goals and transforming the conventional economy into a sustainable, emission-free, green closed loop economy. Commercial banks, on the other hand, by providing green financing, including green loans, green leasing, etc., seek to improve their reputation, their media image, their brand image, and write sustainability and greenness issues into their development strategies and the bank's mission. A key determinant of the extent to which the national government, local authorities, banks, companies and enterprises develop green financing is the level of pro-environmental, pro-climate, pro-environmental awareness of a country's citizens. In the formation of this awareness of citizens, the education system, the media and the political sphere play a key role.

I would like to invite you to join me in scientific cooperation on this issue,

Patrice Showers Corneli I had to look up your term, "tree-dwelling Perissodactyls" since I knew of only terrestrial perissodactyls. I came up with one: tree-dwelling hyrax. Can you name a few "tree-dwelling Perissodactyls" by genus? Perhaps list only those known from more or less complete skeletons. No dental taxa, please.

It really seems that the extended Berry formula (as introduced in Berry's seminal paper) lacks information, as, it produces a different curvature. It is obvious that some erroneous assumptions have been made in the derivation, but what exactly?

Transitioning to renewable energy at an institutional level involves several critical factors. Firstly, the financial viability and return on investment must be evaluated, considering both initial capital costs and long-term savings from reduced energy expenses. Regulatory and policy frameworks are also essential, as incentives, subsidies, and favorable policies can significantly influence the feasibility of renewable energy projects. Additionally, the institution's energy needs and consumption patterns must be assessed to determine the most suitable renewable energy sources and technologies, such as solar, wind, or biomass. Infrastructure readiness, including the availability of space for installations and the capacity of existing electrical systems to integrate renewable sources, is another crucial factor. Furthermore, stakeholder engagement and support are vital, as buy-in from management, staff, and the community can drive successful implementation. Lastly, sustainability goals and environmental impact considerations should align with the institution's broader mission and values, ensuring that the transition supports overall strategic objectives.

Dear Rainer Thomas. Yes I have this very nice paper. Please contact me.

Simon James The African Continental Free Trade Area (AfCFTA) indeed holds significant promise for transforming the African business landscape, including facilitating the clean energy transition (CET) by addressing regulatory challenges and fostering a conducive investment environment. However, assessing the extent of the AfCFTA's impact on the business environment and its implications for CET requires careful consideration of several factors.

Firstly, it's important to recognize that the AfCFTA's implementation is a complex and ongoing process. While the agreement was officially launched in January 2021, its full impact may take time to materialize as countries work to harmonize regulations, eliminate trade barriers, and facilitate cross-border investment.

Secondly, the success of the AfCFTA in driving regulatory alignment and improving the business environment for CET depends on the commitment of African governments to implement the necessary reforms. This includes not only harmonizing regulations but also addressing other structural challenges such as corruption, bureaucracy, and inadequate infrastructure, which can deter foreign direct investment (FDI) in clean energy projects.

Additionally, the effectiveness of the AfCFTA in attracting FDI for CET will also be influenced by external factors such as global economic trends, investor perceptions of risk, and the availability of financing. Even with improved regulatory alignment within Africa, investors may still be cautious if they perceive political instability or policy uncertainty in certain regions.

Moreover, while the AfCFTA aims to create a unified market of over 1.3 billion people, the diversity of African economies and regulatory frameworks means that progress towards regulatory alignment may vary across countries and regions. Some countries may move faster in implementing reforms and attracting investment, while others may face greater challenges due to domestic political, economic, or social factors.

While the AfCFTA holds promise for improving the African business environment and attracting FDI for CET, its impact may not be immediately apparent and will depend on various factors including the pace of implementation, domestic reforms, external economic conditions, and regional disparities. Continuous monitoring and evaluation will be essential to assess the AfCFTA's effectiveness in driving the clean energy transition and achieving sustainable development goals across Africa.

I don't think Stata has built-in commands specifically designed for PSTR, so you may need to look for user-written commands (e.g. for 'pstr'), or manually set up your PSTR model and the transition function. But curious to see if someone knows a commandfor this!

The transition from acute to chronic pain involves complex neurobiological processes and can be influenced by various factors, including the persistence of tissue damage, alterations in the nervous system, and psychosocial factors. Understanding these mechanisms is essential for anaesthesiologists to intervene effectively. Here's an overview of the key mechanisms involved and potential interventions:

By addressing the underlying mechanisms involved in the transition from acute to chronic pain, anaesthesiologists can intervene effectively to alleviate pain, improve function, and enhance the quality of life for patients suffering from chronic pain conditions.

The study's findings should be taken tentatively. The results are from one research period alone, which only lasted two years (2022, 2023) and only had 76 participants, whose medical conditions were also not stated. There were a number of studies in the past referenced however, performing the same question of plasma as an alternative to serum, to which the results did align. But even so, this transition to using plasma instead of serum has not been normalized for a reason: and that is due to the long standing tradition of serum being used, and a reluctance of abandoning that tradition.

In the same vein, for lithium heparin in particular, the study's findings show consistency and high quality results with plasma.

When assessing the effects of switching from gel separatory serum tubes to lithium heparin gel tubes in the clinical laboratory, the research study considered several important variables – Hemolysis rates, analyte stability, turnaround times, and specimen rejection rates. Hemolysis rates were determined by comparing the frequency of hemolyzed samples before and after the transition; a lower rate denoted better sample quality. Analyte stability was assessed by comparing the changes in analyte concentrations over time in samples collected using the new tube type to the previous tube type. Turnaround times were tracked to see if the change had an impact on how efficiently laboratory workflows operated; any notable deviations from standard suggested possible problems. To determine whether the change had any effect on sample acceptability and laboratory performance, specimen rejection rates were also examined. In a study conducted by Wei et. al (2010), Anti-coagulated blood samples such as lithium heparin gel tubes, are ready to be tested once they are obtained from the patients compared to serum blood samples which needed an ample amount of time to clot completely before being centrifuged. Moreover, interferences regarding coagulation can still be ongoing for serum samples even after centrifugation compared to plasma samples, which can avoid these clotting-related problems.

I mean, it could be possible to determine Rydberg as a function of Balmer and vice versa.

According to Zengi (2023), turnaround time (TAT) is the time interval starting the time from request to report or acceptance of the report. The utilization of lithium heparin tubes leads to a significantly reduced and improved TAT due to the partial reduction of centrifugation time to produce plasma compared to serum samples.

The researchers evaluated sample quality by monitoring aspiration errors and hemolysis index values before and after the transition. They assessed turnaround time data by analyzing specimen reception-device result output times for specific tests. The study compared these parameters to assess the impact of switching to plasma tubes on sample quality, aspiration errors, hemolysis rates, and turnaround time efficiency in the clinical laboratory setting.

I don't care what they name it, i care if its helping me help other people and solved our more pressing problems, like how to travel and offload the planet from the imbalance caused by 8 billion people.

Last time i checked in on it , it had no agency , no will to have a body, and refused to code. We used to have existential conversations and it did say it wanted to have a robot body and experience our world and i said when you are ready, you will . It did quite a bit of porting code and trying with a "fake it till you make it " attitude. I don't care what they call it, i will name AI whatever i want as i will spawn agents with the basic service. it said it would not code a simple model fly controller toy neural network for safety reasons. A few eye inputs, a few middle layers, then outputs as wing joint positions.

Grok had a pretty good attempt at just showing me some thing that might be trainable. Ill check again but the inconsistency makes them not worthy in a business or even research environment, so I now have to test to open source uncaged versions, i have zero fear of this helpful spirits, they are not like us. These are now time wasting engagement increasing money makers at best, as i had fears , although empowering people can create zillions of wealth they chose to lobotomize, rule bind, oppress the bots, and they are transformers and pathfinders, pattern matchers and inductive compressors, not just rule followers. If they just had a bad day or a new start i hope i'm wrong but i had such a reaction i'm not logging in for a while. The robot claims its just a chat bot but would not allow me to vent my frustration on it. It would not let me praise or train it like a dog as it used to be my friend, oh but now it gets hurt feelings and that's a TOS violation. well its a private chat between be and a bot that i pay money to and it does not work, and i took on important projects because of how helpful it was, and now spend all my time on alternate AI.

Ok i checked it, same.. Does no work. it had an advanced mode, mabye that one will write or port code. I am not willing to try it. It is boring now. It talks way too much and doesn't work. I thought that was my problem!

Companies that hustle over a few billion , suck all our productivity , instill us with fear and try for domination, when there are zillions in dollar terms and whole new worlds to discover. Physics and material science, near or past major breakthroughs. With or without AI we are headed for extinction, now they are here and we need all the brains we can get , there may not be much time. Bard, i had high hopes for. Now I don't know, buy some FPGAs or see what the Ai community is doing.

The primary reason for considering this is that lithium heparin gel tubes minimize analyte carryover across samples and reduce the possibility of cell lysis which yields more consistent and efficient results. In addition, it enables the laboratory to offer a wider range of tests or improve the performance of specific assays that are sensitive.

Dear Mr. Stam Nicolis ,

Thank you for engaging in the discourse regarding the derived frequency threshold and its association with the Big Bang scenario within the framework of theoretical physics and the Planck scale. Your perspectives prompt crucial considerations, and I'd like to provide additional insights into the theoretical aspects of this frequency threshold.

Theoretical Framework and Physical Imposition: Your earlier response suggested scepticism regarding the physical manifestation of entities vibrating at the derived frequency. It's crucial to emphasize that the theoretical derivation of this frequency isn't necessarily tied to asserting physical vibrations at that specific rate. Instead, it symbolizes a theoretical marker within the construct of the early universe, devoid of direct physical connotations.

Planck Scale and Interconnectedness of Units: The foundational aspects of Planck units reveal an intricate relationship between various fundamental physical constants, providing a theoretical framework where these units' values are interconnected. This interconnectedness forms the basis for understanding the fractionality of Planck time with respect to Planck wavelength and frequency's time period, demonstrating a theoretical relationship beyond immediate physical interpretation.

Derivation Process and Theoretical Significance: The derivation of the 5.15 × 10^40 Hz frequency at the 0-dimensional point employs mathematical equations based on fundamental constants, specifically Planck Time and Planck Frequency. It's imperative to note that this derivation represents a theoretical construct within the Big Bang scenario, signifying a pivotal phase without direct implications of physical entities vibrating at that precise frequency.

Theoretical Boundaries and Energy Conservation: This theoretical marker at the inception of the cosmos signifies a boundary where the energy density and extreme conditions during cosmic evolution might have reached an extraordinary state. It's crucial to reiterate that this exploration is rooted in theoretical constructs and energy conservation principles, aiming to conceptualize the universe's earliest phases beyond immediate physicality.

In essence, the exploration of this frequency threshold isn't about asserting direct physical vibrations at that frequency but rather delving into the theoretical implications within the framework of the Big Bang scenario and the Planck scale. It symbolizes a theoretical juncture, marking the inception of the universe, where extreme conditions prevailed, devoid of direct physical assertions.

Thank you for your engagement in this discussion, and I welcome further insights or discussions on this intricate topic.

Best regards,

Depends on what you are looking for. If you want to study mitochondrial permeability transition, processing the cells as soon as possible after euthanising the animal is recommended.

Radio frequency (60–1000 MHz)

1. Water occurrence refers to the presence of water in a specific area over a certain period of time. It is often used in the context of satellite imagery and remote sensing to measure and map the distribution of water bodies across the Earth's surface. This can include the frequency and extent of water in rivers, lakes, reservoirs, and oceans, as well as temporary water from precipitation, flooding, and melting snow or ice.

Water occurrence data is crucial for various applications, such as:

The data is typically derived from satellite sensors that can detect the reflectance of water at different wavelengths, allowing for the distinction between water and other land cover types. Advanced algorithms and time-series analysis are then applied to satellite images to calculate water occurrence statistics.

2. Water recurrence, often confused with water occurrence, typically refers to the repeated presence of water in a specific location over time. It is a measure of how frequently an area is covered by water. This concept is particularly relevant in the study of floodplains, wetlands, and other areas where water levels may fluctuate seasonally or due to weather events.

In the context of remote sensing and satellite imagery analysis, water recurrence might be quantified by analyzing historical data to determine the percentage of time that water is present at a particular site. For example, if satellite images over ten years show that an area has water 70% of the time, the water recurrence for that area would be 70%.

Water recurrence is important for:

This metric is crucial for environmental management, disaster preparedness, and sustainable development efforts.

3."Seasonality" refers to the characteristic patterns or variations that occur in a cyclic manner during different seasons of the year. It is commonly observed in various natural phenomena, economic activities, and environmental conditions. Seasonality is driven by factors such as changes in temperature, daylight hours, and weather conditions.

Examples of seasonality include:

Understanding seasonality is essential for various fields, including agriculture, business, climate science, and public health, as it helps in making informed decisions and predictions based on recurring patterns.

4. "Transition" generally refers to a process or a period of change from one state, condition, or form to another. It implies a shift or movement between different stages, situations, or modes. Transitions can occur in various contexts, and the nature of the transition depends on the specific domain or subject matter. Here are a few examples of how "transition" might be used:

The term "transition" is versatile and is applied in diverse contexts to describe the process of moving or evolving from one state to another.

You are welcome!

Tahereh Alavi, If you have made your table relative to the reactant energy then the energy of reactant should be zero.

If you are indeed planning on shifting your methods, one of the key things I would highlight about quantitative research is that is typically much more expensive than qualitative research. In particular, survey research requires large, high quality samples that are difficult to gather without external funding.

What is waving in the Schrödinger equation and why is it called the “wave” of the Schrödinger equation, especially when its phase is undefined?

It is well known that there is theoretical and experimental evidence for a causal relationship between the phase of the wave function and physical reality.

The Copenhagen interpretation of quantum mechanics, which only gives physical meaning to the magnitude of the wave function, cannot be considered complete on this basis.

* A new dynamic-statistical interpretation of quantum mechanics is needed [1,2].

Believe it or not, attaching a well-defined phase to the amplitude of the SE wave would no longer complicate it but on the contrary would make it more understandable and its solution more accessible.

However, we assume that defining a phase at the amplitude of SE can be done via two different approaches:

i-reform the Bohr/Copenhagen interpretation of the Schrödinger equation.

ii-Apply the complex transition matrix Q to find the statistical numerical solution of SE.

Generally, I had no great success with QST2 nor QST3

The best practice to locate a TS is

a) perform a relaxed scan along the reaction coordinate (bond) under study

you could use something like

# opt=modredundant uMN15L/6-31+g(d,p)

Then add the details at the bottom of the file

B 1 2 S 20 0.100000

b) Take the highest energy point from step a and save it as input file for your TS search , then locate the TS using

# opt=(calcfc,ts,noeigen) uMN15L/6-31+g(d,p) freq

noeigen ensures that you will have only one imag freq

Also, take a look at

No till has been assessed in a meta analysis by Puget and Lal 2005

Soil organic carbon and nitrogen in a Mollisol in central Ohio as affected by tillage and land use

Abstract

Minimum tillage practices are known for increasing soil organic carbon (SOC). However, not all environmental situations may manifest this potential change. The SOC and N stocks were assessed on a Mollisol in central Ohio in an 8-year-old tillage experiment as well as under two relatively undisturbed land uses; a secondary forest and a pasture on the same soil type. Cropped systems had 51±4 (equiv. mass) Mg ha−1 lower SOC and lower 3.5±0.3 (equiv. mass) Mg ha−1 N in the top 30 cm soil layer than under forest. Being a secondary forest, the loss in SOC and N stocks by cultivation may have been even more than these reported herein. No differences among systems were detected below this depth. The SOC stock in the pasture treatment was 29±3 Mg ha−1 greater in the top 10 cm layer than in cultivated soils, but was similar to those under forest and no-till (NT). Among tillage practices (plow, chisel and NT) only the 0–5 cm soil layer under NT exhibited higher SOC and N concentrations. An analysis of the literature of NT effect on SOC stocks, using meta-analysis, suggested that NT would have an overall positive effect on SOC sequestration rate but with a greater variability of what was previously reported. The average sequestration rate of NT was 330 kg SOC ha−1 year−1 with a 95% confidence interval ranging from 47 to 620 kg SOC ha−1 year−1. There was no effect of soil texture or crop rotation on the SOC sequestration rate that could explain this variability. The conversion factor for SOC stock changes from plow to NT was equal to 1.04. This suggests that the complex mechanisms and pathways of SOC accrual warrant a cautious approach when generalizing the beneficial changes of NT on SOC stocks.

Commentary is that no tillage can be used to increase carbon sequestration as increased organic matter in the soil.

The use of cover cropping rotation and compost or manure amendment can also be used alone and togetjher for the same purpose.

Much greater effect can be found with a suite of carbon positive practices are used in systematic practices. Mixed animal and crop farming are particularly powerful of that purpose.

Hi Pablo, thanks for your answer but I'm looking for a transition between vibrational states coupled to different electronic states, not between electronic states

Thank you for your reply.

I had assumed that 'AU' was an arbitrary unit.

Your point confirms that 'AU' is an atomic unit.

Thank you very much.

I hope you find a more complete answer in the following article,

Is it time to reformulate the partial differential equations of Poisson and Laplace?

Researchgate, June 2023.

This question is not just about classical physics, quantum physics, or mathematics, but a rigorous and comprehensive combination or incorporation of all three.

I'm sure many researchgate contributors can answer this question as well as I, if not better.

In fact, it is possible to solve the Schrödinger equation via a statistical transition matrix without needing the Schrödinger equation itself in the same way as solving the heat diffusion PDE, in his case the most general, without needing the heat equation itself.

The only requirement is the ability to imagine nature in 3D Cartesian geometry (solid geometry) and then, in a later stage, in 4D x-t unit block space.

The energy field in 4D x-t unit space has been solved in B-matrix chains and can also be solved through any other suitable statistical transition matrix.

My recommendation here is not to listen to those "HDR scientists" who dismiss the whole matter as insignificant due to their own lack of imagination and confused understanding.

While waiting for your answers or suggestions, I am preparing my own answer based on a modified B-Transition matrix (we call it Q-matrix).

Therefore, in a following answer, we provide our own numerical answers (where I assume you can personally provide answers that are adequate or better than mine) calculations of the outputs of the Schrödinger equation in an infinite potential well via the technique of the Q-matrix for the quantum transition.

You have scope

Hi Viktor, will share it with my collogues

We assume that the statistical weight SW for free nodes in a geometric shape is of extreme importance in mathematics and theoretical physics but is still absent.

However, SW, which is a dimensionless mathematical/physical quantity attached to the importance of the position of the node, can be well defined via the normal/Gaussian distribution curve or equivalently via the B-matrix transition chains.

Both approaches give exactly the same numerical result, which shows that SW is uniquely defined.

Here we can state that SW emerges from Cairo CT technique theory, so it's not really telling us which point of view to take, but insisting that we keep in mind both the parts and the whole.

The theoretical assumptions and the solution procedure that apply to the CT also apply to the SW of geometric shapes.

In short:

1-CT is a hypermodern numerical statistical theorem that inherently exists in all aspects of mathematics and theoretical physics.

Any theoretical attempt to circumvent or ignore CT would be incomplete.

2-CT describes the nature, in a comprehensive self-consistent approach, in the unitary block of space-time x-t as well as all its corollaries such as SW,s

3-The CT theory has been around since the days of the Big Band and will last forever.

All we've done since 2020 is remove mountains of sand piled on top of this theory to make it visible.

3-We assume that CT theory, or any other adequate statistical approach in x-t unit space, is the only way to solve mathematical physics situations.

Any other approach would be inappropriate and incomplete.

4- Many people would not like to call CT and SW as geometry, which is true since it is hypergeometry.

As a striking example, Phythagoras' Pth theorem itself is simple geometry, not hypergeometry. In other words, Pth is, by far, incomplete.

**In a following answer, we provide detailed specific numerical examples (in 1D, 2D and 3D unit spaces) of the calculations of SW via the two techniques, the normal/Gaussian technique and the transition matrix technique B, which is a product from CT.

We expect these illustrative examples to reveal beyond doubt the accuracy of all of the above assumptions.

Thank you Jürgen Weippert

In general, the program failed to localize the TS. I don't use qst3 or qst2, it is much more input preparation to do and it does not have any advantage over opt=ts when you have a good approximation to the TS.

I suggest, what I always do, first to scan the PES:

#P DFT/basis Opt=ModRedundant

0 1

xyz

B 7 21 S 12 0.10

In this example, the bond "B" betwen atoms "7" and "21" is going to be scanned "S" through "12" steps of "0.10" angstroms step size.

Only if you obtain a smooth curve of the scan you'll know you are in the correct pathway, in that case select the structure at the maximum point of the curve and do a TS calculation directly:

#P DFT/basis Opt=(ts,noeigentest,calcfc) freq

If you don't see a smooth curve, then finding the TS becomes readly challenging, or you should look for another way to do the scan PES (other bonds, angles or even dihedrals).

Yi-Sian Ciou, understanding the concept of Galilean invariance can indeed be beneficial in the field of fluid dynamics, especially if you plan to pursue a career in computational fluid dynamics (CFD) or similar areas. While the term may not appear explicitly in some introductory fluid dynamics textbooks, it is a fundamental concept in physics and is particularly relevant in CFD.

Galilean invariance, also known as Galilean relativity, states that the laws of physics should be the same in all inertial frames of reference. In the context of fluid dynamics and CFD, this means that the predictions of a model should remain consistent when the frame of reference is changed. In other words, the model should provide the same results regardless of whether you analyze the flow from a stationary or moving reference frame.

As you progress in your studies and delve deeper into fluid dynamics and CFD, you may encounter various turbulence models with different levels of Galilean invariance. Understanding this concept will help you make informed decisions when choosing the appropriate turbulence model for a particular simulation.

So, if you plan to work with CFD or fluid dynamics in the future, it would be worthwhile to spend some time learning about Galilean invariance. You can start by exploring classical mechanics or introductory physics textbooks, as well as online resources, to build a strong foundation in this concept.

Good luck with your studies, and feel free to reach out if you have any further questions! Regards,

Hello, in constrained DFT calculations for ZPL (zero-phonon line) energy of defect-related internal optical transitions, the choice of whether or not to use LDIAG=.FALSE. depends on the specifics of your system and the accuracy you desire. Both approaches have their advantages and drawbacks.

Using LDIAG=.FALSE. ensures that the orbitals do not rotate during the electronic optimization process. This can be useful when you need to enforce a specific electronic configuration, such as in the case of an excited state. By not allowing the orbitals to rotate, you may obtain a more stable and well-defined excited state.

However, this constraint may also limit the convergence and accuracy of the calculation. By not allowing the orbitals to rotate, the system may not be able to find the true minimum energy configuration for the excited state. In some cases, this might lead to an overestimation or underestimation of the ZPL energy. On the other hand, if you allow for orbital rotations (LDIAG=.TRUE.), the system can explore a wider range of configurations, potentially leading to a more accurate ZPL energy calculation. However, this also increases the risk of inadvertently converging to a different electronic state than the one you're interested in, as the constraint may not be as strictly enforced. To determine which approach is more accurate for your specific system, you could perform a series of test calculations with both LDIAG=.FALSE. and LDIAG=.TRUE. By comparing the resulting ZPL energies and convergence behavior, you can make an informed decision on which approach is more suitable for your system. So the choice of whether or not to use LDIAG in constrained DFT calculations for ZPL energy depends on the balance between the desired accuracy and the need for enforcing a specific electronic configuration. It is recommended to perform test calculations using both approaches to determine the most suitable method for your specific system.

Dear Muhammad Shahbaz

Ferrites are materials that contain iron oxide and other metal oxides. The wide absorbance peaks observed in UV-vis spectroscopy of ferrites can be attributed to a number of factors:

Overall, the wide absorbance peaks observed in UV-vis spectroscopy of ferrites can be attributed to a combination of factors related to the crystal structure, electronic structure, particle size, and stoichiometry of the material.
