I've been trying to produce result for the paper of Deep Reinforcement Learning-Based Resource Allocation in Cooperative UAV-Assisted Wireless Networks. I am having difficulties in understanding logic of Phase2: Transmission from UAVs to UE which I only implemented set of UE group associated to UAV, not randomly distributed as in the paper. I'm wondering if someone can help me. I'd appreciate if I can get source code as a reference. Thank you.
Why and how is this kind of long-term potentiation (LTP) possible?
Is LTP even needed for all sorts of synaptic plasticity and long-term memory formation?
Long-term potentiation (LTP which is necessary for synaptic plasticity and long-term memory formation) needs repeats and reinforcement of the engrams to be triggered.
However, apparently everybody automatically "absorbs" a lot of information immediately and also permanently, even without needing any extra effort (at least any conscious effort), which seems to be needed for LTP to happen. Everyone seems to have this ability, although it is even stronger in those with better memories.
People simply "learn" many things once; and many of those learned items remain there for a pretty long duration, and in many cases even for the rest of their lives. This seems to happen without any repeats, at least without any apparent or conscious efforts to remember or re-remember those memories. This is the case for a lot of semantic information (especially the information of interest or importance to the person) as well as a large portion of the contents of episodic memory.
Why and how is this kind of LTP possible?
Perhaps attention plays a major role here, e.g., being interesting and important automatically triggers LTP without a further need for repeats.
But such effortless long-term memorization happens also in the case of a lot of semantic information or autobiographical events that are not inherently interesting or significant to the person.
Is LTP even needed for all sorts of synaptic plasticity and long-term memory formation?
To produce a composite material, how will I weigh the components mentioned above if I want to make this mixture?
Recently, I want to study the acoustoelastic effect of Lamb wave in composites, and use this property to measure the stress of carbon fiber reinforced composite T300/QY8911. The third order elastic modulus parameters of materials are required for the acoustic elastodynamics modeling. However, I only found the relevant parameters of T300/5208 in the paper, and did not find any relevant parameters of T300/QY8911. I wonder if anyone knows these parameters and would like to share them, I would appreciate it!

Hi! I am a little confused about mentioning the reinforcement details in the figure showing the skeleton of my 2D RC frame. It has 32 columns (in which case I can show half the structure since it's symmetric. Thus, 16 columns are shown) and 24 beams. Should I mention the reinforcement details in the figure like the one attached, or is it fine to only mention the dimensions of each member?

- The reinforced solid beam's (300mmx300mm) ultimate load capacity is 150.34 kN
- The same beam with 90mm dia hollow at the center's ultimate load capacity is more than that of the solid beam. However, at 20 mm and 50 mm dia hollow, the ultimate loads are 143.61 kN and 138.65 kN, respectively.
- Moreover, I'm getting inaccurate results with voided beams with hollow on the top and the bottom portion. Why?
- My beam is simply-supported with an impactor on top and I used SOLID65 and customized a rebar material.
- Also, I'm not sure if I am doing the right thing on how to get the ultimate load capacity.
although glyerol have more OH group

I am doing Finite Element Analysis of spirally reinforced concrete columns on ATENA 3D. I am perplexed while defining the spiral reinforcement as there is no option available for it. So far what I have understood is I need to define joints for spiral then connect them using line segments. For this option, I need to calculate the coordinates of joints manually, which is surely a hectic. If you can help me then please do.
How are you?

Previous test showed that polypropylene fiber has poor adhesion to epoxy resin. Consequently, the mechanical properties of reinforced resin are reduced. From some literatures, the reason for poor bond properties is that the surface of polypropylene fibers lacks active groups. I know that both the polypropylene fiber and epoxy resin are hydrophobic. I have a question. How to improve the bond between polypropylene fiber and epoxy resin, and related mechanisms.
i am trying to do reliability analysis for short rc columns. i am referring a paper "reliability analysis of eccentrically loaded columns" by "Maria M. Szerszen, Aleksander Szwed and Andrzej S. Nowak".
in the end, based on a plot of 'strain' vs 'strength reduction factor', they have proposed a new values of strength reduction factor as a function of strain.
two models have been proposed, the dotted one is for all the points except black
while the solid line is for black points.
black points are depicting reinforcement ratio < 2
green, blue, red colors are showing reinforcement ratios in excess and equal to 2
my question is how they fitted these two lines, or, how they have measured the transition zone from the given scatter plot?

I have a research topic is concerning about the creep rupture of Fiber Reinforced Polymer Matrix Composite Bars, my question is related to D7337/D7337M Standard, specifically is in section 9, subsection no. 9.2.2, where the standard limit the rupture of one of the specimens to be after 8000 h (More than 11 months), can I have an answer for why we need to reach 8000 h, in order to determine the one million hour creep rupture capacity?
I currently performed an EIS analysis but could not get a semicircle in the Nyquist plot. The material being tested in 1.5% NaCl is aluminum matrix composite (AMC) reinforced with SiC particles and coated with ZrO2 thin film by ALD. In other words, ZrO2 was deposited on AMC as a protection layer against corrosion. The frequency region was set from 100000 to 0.01 Hz. Does the result show poor coating? I wonder how I should interpret the result and what to do next.

I've recently read many articles about fiber reinforced UHPC use in balistics. About 70-80 % of them say that adding fibers to UHPC increases ductility, but I think that this is not accurate because these materials don't behave in a way ductile materials like steel or termoplastics behave. They instead behave more like thermosetting plastics or ceramics. Wouldn't calling it tough be more accurate?
