Scalable molecular representations enabled by multimodal fusion and sequence distillation

Molecular prediction depends on how chemical structures are represented, yet descriptors capture only partial aspects of chemical information. Here, we show that the Chemical Dice Integrator combines six complementary molecular views spanning physicochemical properties, molecular...

An adaptive methodology for determining the optimal transition point and reuse lifespan of photovoltaic panels considering degradation-adjusted energy yield

End-of-Life (EoL) management of Photovoltaic (PV) panels is an emerging concern for waste managers and policymakers, given the high rates of PV deployment worldwide. Existing studies emphasize the benefits of PV recycling, but there are few assessments of panel reuse. Identificat...

Enhanced nocturnal N 2 O 5 -ClNO 2 chemistry in Delhi under reduced NO conditions

Nitryl chloride (ClNO 2 ) is an important Cl⚫ precursor, originating from the heterogeneous reactions of dinitrogen pentoxide (N 2 O 5 ) on chloride-containing particles. This N 2 O 5 -ClNO 2 chemical process plays critical roles in chloride activation, nitrate formation, and th...

Ultra-fast spin Hall nano-oscillator based microwave spectral analysis

Abstract Ultra-fast spectrum analysis based on rapidly tuned spintronic nano-oscillators has been under development for the last few years and has already demonstrated promising results. Here, we demonstrate an ultra-fast microwave spectrum analyzer based on a chain of five mutua...

Bridging Performance Gaps in Organic Photodetectors: A Critical Review of Metal-Semiconductor-Insulator-Metal (MSIM) Architectures, Charge Dynamics, and Device Stability

Organic photodetectors (OPDs) have emerged as promising candidates for next-generation optoelectronic technologies owing to their mechanical flexibility, lightweight nature, low-cost fabrication, and spectral tunability. Despite significant progress, conventional OPD architecture...

C2f-space: coarse-to-fine space grounding for spatial instructions using vision-language models

Abstract Space grounding refers to localizing a set of spatial references described in natural language instructions. Traditional methods often fail to account for complex reasoning— such as distance, geometry, and inter-object relationships— while vision-language models (VLMs),...

Comparative analysis of deep learning approaches for electrothermal and state of health estimation in lithium-ion batteries under variable thermal conditions

Due to prolonged operation and repeated charge–discharge cycles, lithium-ion (Li-ion) batteries undergo gradual degradation that impacts system reliability, safety, and lifespan. To enable precise health tracking in intelligent battery management systems (BMS) and overcome the li...

GLOBAL REGULARITY OF THE THREE-DIMENSIONAL INCOMPRESSIBLE NAVIER-STOKES EQUATIONS VIA NON-SINGULAR EMBEDDING IN A FIVE-DIMENSIONAL CONTINUOUS FLUID VACUUM

We present a formal proof of the global regularity and smoothness of the threedimensionalincompressible Navier-Stokes equations on the domain R3×[0,∞). By transitioningfrom a rigid, non-relativistic four-dimensional spacetime coordinate system to a parameterizedfive-dimensional c...

Comparative aerodynamic performance assessment of NACA 2412 and NACA 0012 aerofoils with winglet integration: a computational study using MATLAB-CATIA-CFD framework
