Restricted Tweedie stochastic block models
Canadian Journal of Statistics, EarlyView.Abstract The stochastic block model (SBM) is a widely used framework for community detection in networks, where the network structure is typically represented by an adjacency matrix. However, conventional SBMs are not directly applicable to an adjacency matrix that consists of nonnegative zero‐inflated continuous edge weights.

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.The solvation structure and dynamics of the SCN− anion in mixed N, N‐Dimethylformamide (DMF)‐water liquid solvents is investigated using classical molecular dynamics simulations. A preferential solvation of SCN− by the water molecules is observed in the first hydration shell, followed by a second shell consisting by both DMF and water molecules.

On pseudo polar-derivatives of abstract polynomials
Journal of Mathematical Analysis and Applications, 1989 If E is a linear space over an algebraically closed field K then a map P: \(E\to K\) is called an abstract polynomial, if for all x, y in E and c in K one has \[ P(x+cy)=\sum^{n}_{k=0}A_ k(x,y)c^ k, \] where \(A_ k(x,y)\) are elements of K, independent of c. The author generalizes the classical concept of a polar derivative of complex polynomials [see,

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments
Helvetica Chimica Acta, EarlyView.ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

JEADV Clinical Practice, EarlyView.Skin frailty (SF) is a common condition affecting adults aged ≥65 years. However, the lack of a validated and reliable visual scale to assess SF severity is a barrier to clinical care and research. In this study, we developed a 9‐parameter Skin Frailty Score (SFS), validated by two board‐certified dermatologists and meeting item and scale level content

Laser &Photonics Reviews, EarlyView.A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Progress in Photovoltaics: Research and Applications, EarlyView.This study introduces a self‐supervised machine learning approach integrating physics‐based principles to estimate open‐circuit voltage (voc$$ {v}_{oc} $$) degradation in photovoltaic systems using SCADA data. By combining clustering and regression algorithms, our method detects performance deviations without labelled datasets.

Quarterly Journal of the Royal Meteorological Society, EarlyView.Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...
