Theoretical Investigation of Superconductivity Properties of Sr1−xKxFe2As2: A Two‐Band Green's Function Approach

open access: yesAdvanced Physics Research, Volume 4, Issue 10, October 2025.
The superconducting (SC) transition temperature (TC) increases exponentially to a maximum as the SC coupling parameter increases for both intra‐ and inter‐band interactions. Strong electron–electron interaction within the hole intra‐band leads to the maximum TC.

Estimands for Early‐Phase Dose Optimization Trials in Oncology

open access: yesBiometrical Journal, Volume 67, Issue 5, October 2025.
ABSTRACT Phase I dose escalation trials in oncology generally aim to find the maximum tolerated dose. However, with the advent of molecular‐targeted therapies and antibody drug conjugates, dose‐limiting toxicities are less frequently observed, giving rise to the concept of optimal biological dose (OBD), which considers both efficacy and toxicity.

Thermal expansion of LaB6 from 298 to 998 K

open access: yesJournal of Applied Crystallography, Volume 58, Issue 5, Page 1635-1642, October 2025.
The isobaric thermal expansion coefficient of LaB6 at 1 atm was assessed from 298 to 998 K. We propose it as a temperature calibration standard for high‐temperature X‐ray diffraction work owing to its high temperature stability.We propose LaB6 as a temperature calibration standard for high‐temperature (HT) X‐ray diffractometry owing to its high ...

Optimal dividends in a discrete-time dual risk model with stochastic expenses

open access: yesAIMS Mathematics
Dividend policies play a pivotal role in financial management by aiming to maximize shareholders' interest and effectively managing risk. In this paper, we explore the optimal dividend strategy in a discrete-time compound binomial dual risk framework ...

Speed of Convergence to Normality When Regressors Are Nonstationary

open access: yesOxford Bulletin of Economics and Statistics, Volume 87, Issue 5, Page 871-879, October 2025.
ABSTRACT Stochastic and deterministic trends always coexist in data generating processes, which causes the nonstationarity and non‐standard distributions of statistics used in inference. It is known that the presence of the deterministic trend leads to asymptotic normality of the t‐statistics.

The weak Lefschetz property for artinian Gorenstein algebras

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3211-3222, October 2025.
Abstract It is an extremely elusive problem to determine which standard artinian graded K$K$‐algebras satisfy the weak Lefschetz property (WLP). Codimension 2 artinian Gorenstein graded K$K$‐algebras have the WLP and it is open to what extent such result might work for codimension 3 artinian Gorenstein graded K$K$‐algebras.

On uniqueness of solutions to complex Monge–Ampère mean field equations

open access: yesBulletin of the London Mathematical Society, Volume 57, Issue 10, Page 3163-3180, October 2025.
Abstract We establish the uniqueness of solutions to complex Monge–Ampère mean field equations when (minus) the temperature parameter is small. In the local setting of bounded hyperconvex domains, our result partially confirms a conjecture by Berman and Berndtsson. Our approach also extends to the global context of compact complex manifolds.
