CyberShake NZ: Probabilistic Seismic Hazard Analysis in New Zealand Using Physics‐Based Ground‐Motion Simulations

open access: yesEarthquake Spectra, Volume 42, Issue 4, November 2026.
This study presents the computational components and workflow developed to conduct probabilistic seismic hazard analysis (PSHA) in New Zealand (NZ) using physics‐based ground‐motion simulations, referred to as “CyberShake NZ.” Semi‐automated procedures generate multiple realizations of kinematic rupture models, create rupture‐specific velocity models ...

Development of a Constructive Method for Verification of Ergodicity and Calculation of the Stationary Distribution of Quasi-Birth-And-Death Processes with Spatially Inhomogeneous Transitions

open access: yesMathematics
The problem of verifying ergodicity and calculating the stationary distribution for continuous-time multidimensional Markov chains with a block tridiagonal generator (Quasi-Birth-and-Death (QBD) processes) is investigated.

Bounded exponential sums with multiplicative coefficients

open access: yesMathematika, Volume 72, Issue 4, October 2026.
Abstract We investigate when the exponential sum Sf(x,α):=∑n⩽xf(n)e(nα)$S_f(x,\alpha) := \sum _{n\leqslant x}f(n)\mathrm{e}(n\alpha)$ is bounded, for a multiplicative function f$f$ and α∈R$\alpha \in \mathbb {R}$. We show that under natural assumptions, Sf(x,α)$S_f(x,\alpha)$ is bounded only when f$f$ is very close to a twisted Dirichlet character χ(n ...

Stem Cell Differentiation Disperses Transcriptional Clusters via a Conserved Surface‐Condensate Trajectory

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Matrix-graphic simulation of social network: ergodic properties

open access: yesSistemnì Doslìdženâ ta Informacìjnì Tehnologìï
We propose mathematical tools for social network simulation to obtain sufficient conditions for network ergodicity, defined as the existence of a steady state as time approaches infinity.

Non‐Hermitian Stealthy Hyperuniformity

open access: yesAdvanced Science, Volume 13, Issue 49, 3 September 2026.
A framework for non‐Hermitian extensions of hyperuniformity and stealthiness is proposed, generalizing PT‐symmetric gain‐loss crystals to correlated disorder in the weak‐scattering limit. By engineering real‐imaginary correlations of the material potential, this framework enables directional scattering phases inaccessible in Hermitian materials ...

Enforced but not Enacted: How Return‐to‐Office Policies Reshape Boundary Enactment, Work‐Location Volition, and Eudaimonic Wellbeing

open access: yesHuman Resource Management, Volume 65, Issue 5, Page 1331-1351, September/October 2026.
ABSTRACT HR faces a conundrum over how to organize hybrid working patterns given the pros and cons associated with conducting work across multiple domains. Many organizations are currently seeking to clarify and often increase the requirements for employee presence at employer premises, meaning studies are needed to better understand how HR should look

Utilizing Exact Values of Transition Intensities for Better Estimation of the Limiting Characteristics of Inhomogeneous Birth-and-Death Processes

open access: yesComputation
In this paper, consideration is given to the class of birth-and-death processes with possibly state-dependent and time-varying transition intensities and a finite state space.

Finite‐Time Protocols Stabilize Charging in Noisy Ising Quantum Batteries

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 9, September 2026.
A transverse‐field quantum Ising chain is charged as a quantum battery using finite‐time ramps, which suppress energy oscillations and stabilize charging compared to sudden quenches. When time‐correlated noise is introduced, the outcome depends entirely on the protocol: noise can either boost stored energy or improve efficiency, never both ...

Navigating Classical and Nonclassical Realms of Nucleation and Crystallization

open access: yesSmall, Volume 22, Issue 50, 7 September 2026.
Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,
