Planar Coulomb Gas on a Jordan Arc at Any Temperature

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study a planar Coulomb gas confined to a sufficiently smooth Jordan arc γ$\gamma$ in the complex plane, at inverse temperature β>0$\beta > 0$. Let Z¯nβ(γ)=Znβ(γ)((2cap(γ))βn2/2e(1−β/2)n(H(νe,γ)−H(νe,I)),$$\begin{equation*} \bar{Z}_{n}^\beta (\gamma)=\frac{Z_n^\beta (\gamma)}{((2\text{cap}(\gamma))^{\beta n^2/2}e^{(1-\beta /2)n(H(\nu _{e ...

Cobalt Single‐Atom Sites Engineered in Poly(Heptazine Imide) Photocathodes as Benchmark for Alkaline Hydrogen Evolution: A Comparative Transition Metal Study

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Cobalt single‐atoms in poly(heptazine imide) photocathodes maximize active‐site availability and outperform Fe, Cu, and Na in alkaline hydrogen evolution. Atomic precision (not bulk loading) proves predominance, establishing a design principle for the next generation of solar fuel devices.

Verification of an Incompressible Viscoelastic Flow Solver Using the Method of Manufactured Solutions for Oldroyd‐B and Giesekus Constitutive Models

International Journal for Numerical Methods in Fluids, EarlyView.
This study utilizes the Method of Manufactured Solutions (MMS) to validate high‐order compact finite‐difference schemes for 2D incompressible viscoelastic flows. By applying Oldroyd‐B and Giesekus models to a lid‐driven cavity benchmark, the researchers rigorously assessed numerical accuracy across varying Reynolds and Weissenberg numbers.

A New Implementation of Network GARCH Model for Stock Volatility and Co‐Volatility Forecasting

Journal of Forecasting, EarlyView.
ABSTRACT Volatility clustering and spillovers are key features of financial time series with many cross‐sectional assets. While network analysis links similar or correlated stocks and helps trace volatility spillovers, contemporary multivariate ARCH‐GARCH formulations struggle to represent structured network dependence and remain parsimonious.

Compact Single‐Shot Incoherent Edge Detection With a Polarization‐Multiplexed Metalens

Laser &Photonics Reviews, EarlyView.
A polarization‐sensitive metalens enables single‐shot incoherent edge detection by generating two polarization‐dependent images and digitally subtracting them to realize a high‐pass optical transfer function. ABSTRACT Edge detection under incoherent illumination is highly desirable for compact vision systems but remains challenging due to the lack of ...

Fragmentation–Coagulation Processes With Advection or Diffusion in Space

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...

On the Reconstruction of Planar Vector Fields From Its Longitudinal and Transverse Ray Transform

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We consider a planar vector tomography problem of reconstructing a complex‐valued vector field from the (complete and partial) information of its longitudinal and transverse ray transforms, as well as from one of those transforms and its first moment.

ON φ-IDEAL WARD CONTINUITY [PDF]

, 2016
An ideal I is a family of subsets of positive integers N which is closed under taking finite unions and subsets of its elements. Let P denote the space whose elements are finite sets of distinct positive integers. Given any element σ of P, we denote by p(

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.
