On the Nonnegative Rank of Positive Operators
Mathematische Nachrichten, Volume 299, Issue 11, Page 3689-3704, November 2026.ABSTRACT In this paper, we introduce the concept of a nonnegative rank of a positive operator T:X→Y$T: X\rightarrow Y$ between ordered vector spaces. In the case of nonnegative matrices, our definition agrees with the standard definition of a nonnegative rank.

IVyTools: Space–Time Image Velocimetry for Streamflow
River Research and Applications, Volume 42, Issue 9, Page 1860-1874, November 2026.ABSTRACT Accurate streamflow measurements are essential for hydrologic monitoring, flood forecasting, and water resource management. Traditional in situ methods, although reliable, are often impractical or unsafe during flood conditions or at inaccessible locations. Image velocimetry techniques offer a potential non‐contact alternative, yet operational

Crucial Role of Magnetic Dipole and Anomalous Field Dependence in NiPS3
Small, Volume 22, Issue 62, 6 November 2026.Torque magnetometry on the prototypical 2D anisotropic magnet NiPS3, together with relativistic density functional theory calculations, uncovers a distinct intrinsic magnetic anisotropy. The characteristic torque pattern, driven by a high‐field spin‐flop transition, reveals its magnetic response beyond standard XY or XXZ models and highlights the ...

What Does It Mean To Be Good at Physics? Peer Recognition in a High School Physics Classroom
Journal of Research in Science Teaching, Volume 63, Issue 9, Page 881-897, November 2026.ABSTRACT In the United States, the Next Generation Science Standards (NGSS) call for science classrooms where students develop a wide range of skills, though students still often hold to narrow views of what it means to be good at science. Science identity provides a lens to examine what students believe being good at science means.

Prediction of Self‐Starting of a Vertical Axis Wind Turbine Using Static Torque
Wind Energy, Volume 29, Issue 11, November 2026.ABSTRACT The ability of vertical axis wind turbines (VAWTs) to self‐start is critical to their performance. There is disagreement in the literature over some of the factors affecting their self‐starting ability and there is very limited information on how the starting azimuthal angle affects self‐starting. We present a series of wind tunnel experiments

More Frequent, Faster, and Seasonally Reorganized Drought‐to‐Pluvial Transitions in U.S. Cities
Earth's Future, Volume 14, Issue 11, November 2026.Abstract Hydroclimatic variability is projected to intensify under continued warming, yet the evolving likelihood, rapidness, and seasonal timing of drought‐to‐pluvial transitions remain poorly quantified. Here, we develop a probabilistic framework that integrates a severity‐resolved Markov formulation to estimate conditional drought‐to‐pluvial ...

Journal of Anatomy, Volume 249, Issue 5, Page 1087-1098, November 2026.Juvenile scolopacid shorebirds possess well‐developed osteological correlates of tactile bill‐tip organs, indicating sensory systems for remote‐touch foraging are present from early life. Ontogenetic changes in bill‐tip morphology suggest ecological specialisation and interspecific variation develop later, after fledging in these highly precocial ...

Advanced Engineering Materials, Volume 28, Issue 20, 21 October 2026.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.
