MORPHOLOGY-CONTROLLED SYNTHESIS OF OCTAHEDRAL NIXFE1-X@C COMPOSITES DERIVED FROM BIMETALLIC MOFS FOR ENHANCED MICROWAVE ABSORPTION
type: item
description: Carbonaceous materials derived from metal-organic frameworks (MOFs) have attracted significant attention as potential electromagnetic wave absorbers due to their tunable structures, high porosity, and large specific surface areas. In this study, a facile strategy was developed to control the morphology of Ni x Fe 1-x -MOFs by adjusting the Ni/Fe molar ratio in the precursors. Specifically, a near-octahedral Ni x Fe 1-x -MOF structure was successfully synthesized at a Ni/Fe molar ratio of 0.5:0.5. Following pyrolysis at 600°C in a nitrogen atmosphere, porous Ni x Fe 1-x @C composites were obtained. The Ni 0.5 Fe 0.5 @C composite exhibited significantly enhanced microwave absorption performance. At a matching thickness of 1.94 mm, the maximum reflection loss (RL) reached -81.35 dB at 13.8 GHz, with a corresponding effective absorption bandwidth (EAB, RL < -10 dB) of 5.3 GHz (ranging from 11.7 to 17.0 GHz). The superior microwave absorption properties are attributed to the improved impedance matching, multiple polarization relaxations, and conduction losses facilitated by the unique octahedral structure. This research provides a novel approach for the fabrication of high-performance electromagnetic wave absorbing materials through the compositional regulation of bimetallic MOF precursors.

AN ADVANCED APPROACHE TO QUANTUM GRAVITY
type: item
description: Making General relativity and quantum mechanics combine into one unified theory of quantum gravity proves to be the biggest scientific challenge facing modern physics. This paper develops a modern approach to quantum gravity as it investigates physical theory development from classic electromagnetism through M-theory to present a new quantum gravity equation. The equation applies Einstein field equation extensions added with quantum-geometric corrections and non-commutative spacetime features and holographic principles to establish new quantum gravity solutions. The ads/CFT correspondence serves as an investigative tool to study quantum space-time behavior for advancing understanding of black hole physics and cosmological and high-energy studies. The speculative equation stands as a major advancement in the effort to bridge macroscopic and microscopic universe descriptions even though it needs additional mathematical and physical evidence to support its validity.

COMPUTATION TO STRUCTURAL AND ELECTRONIC PROPERTIES EVOLUTION OF MONOLAYER MOS2 INDUCED BY STRESS
type: item
description: Based on the first-principles approach of density functional theory, the evolution of the structural and electronic properties of monolayer MoS 2 due to stress is investigated by using the CASTEP module in the Material Studio software, which mainly calculates the changes of the energy band structure of monolayer MoS 2 when it is under different stresses. The calculation results show that: after applying a tensile stress of 1% lattice strain to monolayer MoS 2 , the bottom point of the conduction band in its energy band remains unchanged, but the top point of its valence band will be shifted, so that its energy band structure will be transformed from a direct band gap to an indirect band gap, and with the increase of the stress up to 10%, it still maintains the indirect band gap unchanged but with the consequent decrease of the forbidden band width. On the contrary, when the single-layer MoS 2 is compressed under a compressive stress, when compressed to -10%, the single-layer MoS 2 is transformed from a semiconductor to a metal, and the absorption ability of the light in the layer will be weakened, and the corresponding reflectance will be enhanced to the point of total reflection, which is the characteristic of the metal at this time.

A MULTI-FACTORIAL COMPUTATIONAL ANALYSIS OF BASKETBALL REBOUND DYNAMICS: INTERPLAY OF SHOT GEOMETRY, BALL ROTATION, AND COLLISION SURFACES
type: item
description: This study presents an advanced computational framework for analyzing the physics of basketball rebounding. Building upon a foundational model that uses classical mechanics and Monte Carlo simulations to predict rebound distributions, this research extends its predictive power by systematically relaxing key simplifying assumptions. The study investigates three critical, interconnected domains: the spatial dynamics of rebounds originating from asymmetric court positions, the role of ball rotation (backspin) in altering collision outcomes, and the distinct rebound characteristics of bank shots. By simulating thousands of shot trajectories, we generate high-fidelity, two-dimensional rebound "heat maps" that validate long-standing coaching heuristics about weak-side rebounds from corner shots. Furthermore, the analysis quantifies the energy dissipation effect of backspin, providing a physical basis for the concept of a "soft shooter's touch." Finally, a novel experiment on the bank shot demonstrates that the backboard, as a collision surface, produces significantly more predictable and favorable rebound patterns compared to shots off the rim. The findings are synthesized into a multi-factorial strategic framework, translating complex physical principles into actionable on-court tactics for optimizing rebounding strategy.

THE TECHNOLOGICAL FRONTIER OF COMMERCIAL PHOTOVOLTAICS: CURRENT STATUS AND FUTURE DIRECTIONS FOR SILICON AND THIN-FILM TECHNOLOGIES
type: item
description: This review sheds light on the photovoltaic technologies’ evolving progress, a technology involving light conversion into electricity via the photovoltaic effect. While with main focus on the first and second generation photovoltaic technologies, the scope of this review covers three generations of solar cell materials, examining the triumphs and challenges of the most representative and leading materials for each, in order to delineate the state of the art in the area. The technologies covered include: first-generation crystalline silicon (c-Si), second-generation commercial thin-film technologies such as cadmium telluride (CdTe) and copper indium gallium diselenide (CIGS), and third-generation emerging cells like perovskites. While c-Si is the leading PV technology due to its high maturity, high efficiency, and reliable large-scale manufacturing, its efficiency is limited theoretically. Thin-film technologies offer lower manufacturing costs, but rely on pricier encapsulation and scarce materials. Emerging technologies sit at the research frontier and can potentially surpass the efficiencies of the first and second generations, but lack demonstrated module-scale systems, and, in the case of the most efficient perovskites, face moisture-induced degradation and toxicity concerns. The conclusion is that as dominant technologies reach plateaus of performance improvement, future development focus must shift toward interface-oriented strategies, innovative architectures like the cross-fertilizing tandem cells, and solutions for material and environmental sustainability to continue advancing the field.

THERMAL EFFECTS IN A LD-END-PUMPED PR3+: YLF GREEN LASER
type: item
description: This paper systematically investigates the thermal effects in a laser diode (LD) end-pumped Pr3 + : YLF green laser. Through numerical simulation, the evolution of the internal temperature field under different pump powers (4-20 W) was analyzed. The results reveal that the heat source and temperature exhibit an exponential decay along the crystal axis, with a persistent hot spot at the pump end-face. Increasing the pump power significantly expands the high-temperature region and intensifies the spatial temperature gradient, leading to severe thermal lensing. Furthermore, the dependence of the thermal lens focal length on key parameters was quantified. The focal length decreases nonlinearly with increasing pump power and decreasing pump spot radius, while a larger crystal diameter alleviates the effect by improving heat dissipation. These findings provide critical insights for the thermal management and resonator design of high-power visible lasers.

IMPROVING UAV NETWORK PERFORMANCE WITH ADAPTIVE SHARDING AND AI
type: item
description: This paper presents a comprehensive exploration of the integration of adaptive sharding and Artificial Intelligence to significantly enhance the performance of Unmanned Aerial Vehicle networks. As UAV technology evolves from predominantly military applications to a diverse range of civilian uses—including agriculture, logistics, surveillance, and disaster response—maximizing operational efficiency becomes increasingly critical. The study identifies several key challenges that hinder the effectiveness of UAV networks, such as limited battery life, constraints on communication bandwidth, and processing power limitations. These constraints directly impact the operational range, data transmission efficiency, and real-time decision-making capabilities of UAVs. To address these challenges, we propose an innovative framework that employs adaptive sharding, which dynamically allocates tasks among multiple UAVs based on their real-time capabilities and environmental conditions. This approach not only optimizes resource management but also enhances the network's overall resilience. Furthermore, we leverage advanced AI techniques, particularly deep reinforcement learning, to improve decision-making processes and enhance the adaptability of UAVs in task allocation. By analyzing historical data and real-time conditions, the UAV network can proactively adjust its operations, thereby mitigating potential challenges and improving overall performance. The research evaluates various performance metrics, including latency, throughput, energy efficiency, and reliability, to assess the effectiveness of the adaptive sharding framework. Empirical results demonstrate that the combination of adaptive sharding and AI significantly improves UAV network performance, leading to reduced operational costs and enhanced mission success rates. The findings underscore the transformative potential of integrating adaptive systems and intelligent algorithms in UAV networks, paving the way for more resil…

DATA MODEL SPECIFIC MATRIX AND GAME THEORY APPLICATIONS
type: item
description: Under conventional game theory models, a deeper analysis of players' mixed strategies through probabilistic methods has become a mainstream analytical approach. By infinitely approaching a fixed probabilistic expected value point, traditional equilibrium algorithms in game theory can calculate equilibrium points. However, in most cases, it is not possible to directly make relevant final predictions in games through probabilistic means. As a result, the practical application of game theory is very limited, making it difficult to be widely applied as a module of applied mathematics. This paper provides an overview of the model architecture for the application of game theory through computational mathematical methods based on matrix model calculations. Although it considers fundamentals similar to Nash equilibrium, there are still essential differences.

EXAMINE THE INDEPENDENT DISCOVERIES OF CALCULUS AND THE SUBSEQUENT RIVALRY BETWEEN ISAAC NEWTON AND GOTTFRIED WILHELM LEIBNIZ
type: item
description: The independent discovery of calculus by Isaac Newton and Gottfried Wilhelm Leibniz represents a defining milestone in the history of mathematics and science, highlighting the intellectual genius of both men and the complexity surrounding the recognition of scientific achievement in the 17th century. Newton, working in England, developed his own version of calculus, which he called the “method of fluxes,” as a way to solve fundamental problems in physics, including motion, gravitation, and rates of change. His approach was deeply rooted in physical applications and intuitive reasoning. At the same time, Leibniz, working in Germany, independently formulated calculus with a greater emphasis on mathematical rigor, formalism, and generalization. His systematic notation, including the integral (∫) and differential (dx) symbols, provided a framework that remains the standard in modern mathematics. The rivalry between Newton and Leibniz on the invention of calculus arose in a context of poor communication, nationalistic fervor and mutual distrust. Newton's major work on calculus preceded Leibniz's, as his notes and correspondence show, but the latter was the first to publish his findings in 1684 and 1686. This publication established the its notation and methods in the mathematical community. Newton, however, claimed priority based on his earlier but unpublished contributions, leading to a contentious dispute that lasted decades. National loyalties further exacerbated the conflict, with English mathematicians supporting Newton and continental mathematicians rallying behind Leibniz. This long-running controversy, known as the "Newton-Leibniz calculus controversy," had far-reaching consequences. While it created divisions within the European mathematical community, it also catalyzed rapid advances in the development and application of calculus. The controversy forced mathematicians to refine their methods, clarify concepts, and expand the theoretical foundations of the disci…

BUILDING QUANTITATIVE TRADING SKILLS: INTEGRATING LINEAR ALGEBRA AND CALCULUS INTO STEM PROGRAMS
type: item
description: Algorithmic or quantitative trading, using arithmetic models and statistical tools, has become the essence of today’s financial markets. An excellent theoretical background is crucial for evolving as an expert in this field, and constant training is necessary since different trading models demand linear algebra, calculus, and other forms of mathematics. Linear algebra encompasses matrix operations and vectors, which help sort and analyze big financial data. They help traders understand the relationships among assets, improve their portfolios, and build a new strategy based on factors. Math, which emphasizes derivatives and integrals, is helpful for rates of change, fluctuations, and significant market trends. Combined, these fields provide people with a highly effective arsenal of tools and methods for modelling the market and predicting its action. These skills can be pre-installed in high school and university STEM programs by applying linear algebra and calculus to real-life lessons. For example, using a matrix, students may engage in activities which include optimizing a portfolio and using correlation coefficients in a given risk and return scenario. Some calculus problems that could be used in the teacher instructions could be differentiation to determine the rate of change of an asset price or integration in the determination of accumulative returns. Apart from theory, quantitative trading requires computational skills to support it. Languages such as Python and R make it possible to automate the processing and analysis of large datasets. By integrating mathematical concepts with programming, students are placed in a position where they are Programming Application: Through programming, students can implement simple trading strategies and test them using actual market data. By adopting these interdisciplinary approaches to STEM, students are capable of entering finance-related careers, data science, and other careers. When curricula are aligned with market req…

STUDY OF THE ABSORPTION SPECTRA OF THE FE2+ AND K2FEF4 SYSTEMS
type: item
description: The d-orbital energy level splitting of free Fe2+ ions under electrostatic and spin-orbit interactions leads to d-electron rearrangement and the formation of different energy states, which may result in the occurrence of electron jumps between different energy levels. When Fe2+ is doped with K2FeF4, the combination of electrons in the Fe2+ d-orbitals changes, and accordingly new d-d absorption spectra are generated. In this thesis, from the crystal field theory, the center field approximation method, crystal field matrix meta-algorithm and electron spin-orbit interaction matrix meta-algorithm are used in the study to establish the Hamiltonian quantities of the system and to calculate the fine spectra of the system. Diagonalizing the full energy matrix can yield the Fe2+ d-d absorption spectra, and by analyzing the experimental EPR zero-field splitting (ZFS) parameters Dq, B, C, and Z and combining them with the full energy matrix, the energy values of the Fe2+ energy levels can be derived, and the results of this study show that the theoretical values conform well to the experimental values. My research data can provide some theoretical references for the study of the spectra of crystal doped Fe2+ ions. However, there are also experimental data that have not been derived, and it is expected that they can be supplemented and improved in the future.

type: item
description: Lithium metal has extremely high specific capacity and extremely low redox electrode potential, and is one of the core energy Materials in the field of secondary batteries. However, metallic lithium anodes face challenges such as volume expansion and uneven lithium deposition. Introducing a three-dimensional skeleton into the metallic lithium anode to construct a composite lithium anode is an effective method to alleviate volume expansion and regulate lithium deposition. The composite metal lithium anode has complex composition and structure, and the factors affecting the electrochemical reaction are strongly coupled. With the advancement of physical and chemical models and the large-scale improvement of computing levels, numerical model analysis can effectively study the physical and chemical mechanisms in composite lithium anodes. This article first sumMarizes the core process mechanisms that occur in composite metal lithium anodes and reviews the development of physical and chemical models. Then the quantitative model of the electrochemical Mass transfer process such as the surface electric field and ion field of the composite lithium anode was introduced, and the progress of the analysis and control strategies of the dynamic evolution mechanism of lithium deposition morphology based on the phase field model or finite element model was reviewed. The structural stability of the composite lithium anode during cycling was analyzed from the perspective of the electrochemical field. These quantitative model works reveal the electrochemical principles of lithium anodes and promote the efficient screening and optimized design of composite lithium anodes.
