Large Language Models (LLMs) are machine learning (ML) models that have an increasingly large carbon footprint through their development and use. Efforts to increase the energy efficiency of these models have not translated into reduced consumption due to rebound effects such as Jevons Paradox - that increased efficie…
Aiming at the core requirements of high thermal conductivity, lightweight design, and low cost for spacecraft thermal control systems, this study addresses the industry pain points of traditional multi-layer insulation components, such as heavy weight, cumbersome assembly, and high proportion of launch costs. The rese…
Domain-wall skyrmions (DWSks) hold great promise for high-density spintronic applications; however, how their intrinsic spin texture governs their dynamical behavior remains an open question. By combining micromagnetic simulations with the Thiele formalism, we systematically investigate the dynamics of DWSks driven by…
Visible and short-wave infrared hyperspectral imager (AHSI) of the hyperspectral observation satellite is one of the most important part of the satellite. However, it suffers from heat blockage which could induce thermal deformation and consequently lead to damage of the applications on the satellite. To meet the dive…
In electric traction motors, rolling bearings are vulnerable to electrically induced damage from stray currents and shaft voltages. This study investigated how the current direction affected early-stage degradation of bearings. A specially designed test rig was used to generate simulated unipolar excitations at 20 kHz…
The Lindemann’s melting criterion, which posits that a crystal melts when the root-mean-square atomic displacement reaches a critical fraction of the interatomic distance, has been a cornerstone of simple melting theory for over a century. However, its phenomenological nature and system-dependent critical value limit…
The classical sphere packing problem, which remains unsolved, consists of determining how densely a large number of identical spheres can be packed together. In some sphere packings, the centers of the spheres in a sphere packing form a Euclidean lattice, which is a discrete additive subgroup of $\mathbb{R}^n$. Free $…
We consider the sum of interaction energies of an array of dislocation loops placed on a homogenization lattice as the lattice spacing and diameter of the loops tend to zero. Under suitable well-separation and L2 -boundedness assumptions, a formula for the limit of the total interaction energy is derived in terms of t…
In this paper, we demonstrate erbium ion implantation and signal enhancement in tellurium oxide hybrid waveguides. Silicon nitride strips with a width of 2 $μ$m and a height of 100 nm were clad with a 110-nm-thick tellurium oxide layer to form hybrid waveguides, followed by erbium ion implantation at an energy of 200…
This research project addresses the challenge of improving the solubility of the BCS class IV drug, mesalazine, through innovative co-crystallization techniques. By focusing on the formulation of cocrystals, the study aims to enhance the drug's solubility, bioavailability and therapeutic efficacy. The research involve…
In order to study the influence of pre-debonding depth on the structural integrity of solid rocket motorgrain under typical operational load conditions, numerical simulations were conducted using Abaqus finite element analysis software. The study focused on a solid rocket motor model, analyzing the structural integrit…
Laser welded joint forming, the microstructure and mechanical properties of the base metal (BM) and welded joint of Ti-3573 alloy after laser self-melting welding were studied in depth by means of OM (Optical Microscope) and SEM (Scanning Electron Microscope). The results show that the penetration depth and width decr…
Accurate prediction of the output acoustic power of an ultrasonic therapy system is critical to treatment safety and efficacy. Here, we systematically verify the accuracy of a system-level Krimholtz–Leedom–Matthaei power model that fully integrates the driving source, cable and tuning network, power ultrasonic transdu…
AI systems are increasingly capable of contributing to mathematical research. In research practice, frontier-model reasoning is a limited resource, and expert mathematical review is even more sharply constrained. Allocating these scarce resources well is therefore central to making AI-assisted mathematical discovery e…
The propagation of deterioration in vital reinforced concrete (RC) structures is a critical issue for infrastructure subjected to extreme climate change. Billions of US dollars were spent annually on the rehabilitation of RC structures. Accurate projections of future climate data for each city worldwide must consider…
Solid-state refrigerators using Normal-metal/Insulator/Superconductor (NIS) junctions have previously demonstrated excellent electron cooling but limited ability to cool phonons. The energy gap of the superconductor is used as an energy filter to allow higher than average energy electrons to preferentially tunnel from…
We study sign-changing viscosity solutions of the singularly perturbed fully nonlinear equation $$ F(D^2u_\varepsilon) = \fracα{\varepsilon} β\left(\frac{u_\varepsilon}{\varepsilon}\right) \qquad\text{in }B_1\subset\mathbb R^n, $$ where $F$ is uniformly elliptic and $β\in C_c (-1,1)$ is nonnegative. We prove the scale…
In this paper I will assess WPSR, its past, present, and future and compare it to several other college radio stations.
The future of programming will rely on machine learning. Machine learning is what gives a program the ability to learn and improve based on its own experience. Although this has been better known for improving medical and statistical research, it’s potentiality in the arts is often overlooked. It is overlooked because…
We study the dynamical spin response of UTe$_2$ by using a mixed-dimensional periodic Anderson model. Within the BCS-RPA formalism, we examine how the $f$-orbital character of the quasiparticles affects magnetic excitations in both the normal and superconducting (SC) states. In the normal state, finite mixing between…
