Abstract We present a nonperturbative near-field imaging technique to measure the electromagnetic fields of high-quality-factor (high-Q) terahertz (THz) resonators. The method combines a continuous-wave terahertz spectrometer with a near-field photoconductive antenna (PCA) and Hilbert transform analysis, providing an…
ABSTRACT The oxygen heterogeneity within tumors restricts the therapeutic efficacy of hypoxia‐activated prodrugs (HAPs) and traditional photosensitizers (PSs) when administered alone. To overcome this limitation, we present an oxygen‐unrestricted synergistic therapeutic strategy to concurrently potentiate treatment ef…
Sprites are transient luminous events produced in the mesosphere by quasi-electrostatic fields generated above intense thunderstorms. In this work, sprite streamer discharges are simulated using the Afivo-Streamer framework under mesospheric conditions, employing a fluid plasma model based on the drift–diffusion appro…
Abstract In flexible sensing applications, the long-term reliability of hydrogels is challenged by sustained and cyclic mechanical deformations. Exposure to forces such as bending and stretching ultimately diminishes sensing fidelity and accelerates material fatigue, shortening the functional lifetime. To improve hydr…
Abstract The Hofmeister series provides an empirical description of ion-specific effects, yet a quantitative framework connecting ion-specific hydration to polymer relaxation has remained elusive. Here, we establish such a framework for hydrogen-bonded hydrogels by introducing the dimensionless parameter Bc (the produ…
Traditional algorithmic frameworks for morphological synthesis, such as discrete L-systems, frequently induce structural dissociation under stochastic perturbation regimes due to the absence of geometric inheritance across ancestral lineages. This paper employs a novel algebraic formulation that models autonomous frac…
Variational Quantum Eigensolvers (VQE) require hundreds to thousands of quantum circuit evaluations to converge from random parameter initialization, severely limiting practical application on near-term NISQ hardware. We investigate whether a 13,156-parameter transformer encoder trained on Hamiltonian-to-optimal-param…
Abstract Smart textiles are emerging as next-generation garments developed by scientific and industrial communities and are attracting increasing attention for their ability to provide real-time responses to external conditions or stimuli. Liquid metal (LM)-based smart textiles are widely used in sensors, wearable ele…
Pectin, a natural biopolymer, is a cost-effective, biocompatible, non-toxic, abundant, and flexible material, making it suitable for recording high-quality bioelectric signals from the dynamic surface of the human body. In this work, pectin-based flexible bioelectrodes were developed for the non-invasive monitoring of…
preclinical breast cancer models, and reported clearance pathways and safety profiles. Despite the remaining translational challenges, significant progress is being made in the preclinical development of innovative nanoparticle imaging agents for fluorescence-guided surgery of breast cancer, which demonstrates their p…
Preprint of a research article submitted to the Journal of Theoretical, Computational and Applied Mechanics (JTCAM, https://jtcam.episciences.org).
This publication establishes a closed, rigorous operator-theoretic framework and proof pipeline for the Riemann Hypothesis, synthesizing Appendices 1.1, 1.2, 1.3, Appendix 2, and the master integration Appendix 3. We construct an arithmetic-topological operator $\mathbf{\hat{A}}_{7D}$ acting on the Hilbert space $L^2(…
ABSTRACT High‐temperature proton exchange membrane fuel cells (HT‐PEMFCs) offer enhanced catalytic activity, improved fuel tolerance, and simplified thermal and water management compared with conventional low‐temperature systems. However, their development is hindered by the lack of proton‐conducting membranes that ma…
This revised article addresses Q0169, 'What determines the onset of cavitation and nanobubble stability in chemically complex liquids?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Nanobubble Critical-Radius Stability Model, uses bubble…
Calculation of nonbonded interactions has been a bottleneck for molecular simulations (for molecular dynamics (MD) and Monte Carlo (MC) simulations) that are limiting the system size and the time scale in MD up to nanoseconds. To reduce the computation time/load in calculating nonbonded interactions, an efficient samp…

Industria europeană de apărare traversează o perioadă de accelerare tehnologică, în care platformele aeriene autonome, sistemele energetice solid‑state și infrastructura de testare avansată devin elemente critice pentru competitivitate, reziliență și integrare în programe precum SAFE, EDA, NATO DIANA și inițiativele d…
This study elucidates structure–property relationships governing the thermal fatigue performance of X-ray anodes for medical imaging through an integrated experimental and computational approach. Controlled surface modifications in the form of pre-induced thermal-shock crack networks were introduced into two advanced…
Cathode-Vapour-Feed electrolysers are a special type of Proton-Exchange-Membrane cells. While exhibiting various properties making them especially attractive for applications in the spaceflight industry, their performance is limited by the water...
Coordination compounds with transition metals, especially of molybdenum, are promising cytoprotective agents. In this work, we analyzed the changes in HT-22 cell viability under the influence of molybdenum(VI) Schiff base complexes per se or in cellular injury induced by hydrogen peroxide (annexin V and propidium iodi…
