This work presents a dynamic perspective for comprehending melt flow at the atomic scale and elucidates mechanism by which oxygen bond structures modify viscosity of melt.
We formulate the finite-temperature relativistic Hartree-Bogoliubov theory for spherical nuclei based on a point-coupling functional, with Gogny or separable pairing force. Using functional PC-PK1, framework is applied to study of transitions in Ca, Ni, Sn, and Pb isotopic chains. The force reproduces gaps calculated not only at zero temperature, but also finite temperatures. By performing systematic calculation even-even isotopes, it found that critical temperature transition generally...
To alleviate bone loss, most current drugs target osteoclasts. Saikosaponin A (Ssa), a triterpene saponin derived from Bupleurum falcatum (also known as Radix bupleuri), has immunoregulatory, neuromodulatory, antiviral, anticancer, anti-convulsant, anti-inflammatory, and anti-proliferative effects. Recently, modulation of homeostasis was shown to involve ferroptosis. Herein, we aimed determine Ssa’s inhibitory effects on osteoclastogenesis differentiation, whether ferroptosis is involved,...
Hypersonic vehicles emit strong infrared radiation from their high-temperature exhaust plume and body, which is critical for early warning, tracking, guidance. In this work, a comprehensive analysis conducted on the factors involved in air dissociation reaction within shock layer of hypersonic missile heads, as well multi-component afterburning effect plume. A novel Reverse Monte Carlo Method (RMCM) proposed calculation, utilizes two-dimensional Low-Discrepancy Sequences (LDS) to improve...
A broadband frequency selective rasorber (FSR) based on spoofsurface plasmon polaritons (SSPP) is proposed. The FSR composed of a multi-layer structure comprising surface (FSS)-polyresin (PR)-indium tin oxide (ITO)-PR-FSS and placed vertically metal base plate. periodic square cavity formed. transmission characteristics the are studied by full-wave simulation equivalent circuit method. results demonstrate that under normal incidence, absorption rate remains 95% in 5-30 GHz band, also 80%...
The multi-mode Richtmyer–Meshkov instability is numerically simulated by the large-eddy simulation code MVFT (multi-viscous-flow and turbulence). Vreman, dynamic Smagorinsky, stretched-vortex models are used to model subgrid-scale flux of turbulence transport in simulations. calculated widths turbulent mixing zones all good agreement with experimental results, there a little difference among different SGS models. However, decay factors kinetic energy differ significantly for models, relative...
The subgrid-scale (SGS) terms of turbulence transport are modelled by the stretched-vortex SGS stress model, and a large-eddy simulation code multi-viscous fluid (MVFT) is developed to investigate MVFT problems.

Inspired by the structure of spherical harmonics, we propose truncated kernel stochastic gradient descent (T-kernel SGD) algorithm with a least-square loss function for data fitting. T-kernel SGD employs "truncation" operation, enabling application series-based kernels in descent, thereby avoiding difficulties finding suitable closed-form functions high-dimensional spaces. In contrast to traditional SGD, is more effective balancing bias and variance dynamically adjusting hypothesis space...
In modern warfare, the advancement of low detectable technology has made reduction an aircraft radar cross section (RCS) crucial for survivability, while engine inlets significantly impact overall detectability index as major forward scattering sources. Inspired by absorbing structures (RASs) based on metasurface theory, well spoof surface plasmon polariton (SSPP) this paper proposes a comprehensive design grilles (RAGs) which are installed at inlet aperture intake, where RAGs allow airflow...
