Urban Heat Island in the Eastern Mediterranean and Middle East: Multi‐City Approach in Regional Climate Modelling

open access: yesInternational Journal of Climatology, EarlyView.
This study presents that the WRF model, coupled with bulk urban parameterization, effectively captures the summer urban heat island (UHI) patterns across the Eastern Mediterranean and Middle East, showing stronger night‐time surface UHIs (5°C–6°C) and daytime surface cool islands (up to 12.5°C).

Manin Triples and Bialgebras of Left-Alia Algebras Associated with Invariant Theory

open access: yesMathematics
A left-Alia algebra is a vector space together with a bilinear map satisfying the symmetric Jacobi identity. Motivated by invariant theory, we first construct a class of left-Alia algebras induced by twisted derivations. Then, we introduce the notions of

Assessing Climate Change Impacts on Runoff Variability and Extremes in China Using High‐Resolution Simulations

open access: yesInternational Journal of Climatology, EarlyView.
Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...

Rational points in a family of conics over F2(t)$\mathbb {F}_2(t)$

open access: yesMathematische Nachrichten, EarlyView.
Abstract Serre famously showed that almost all plane conics over Q$\mathbb {Q}$ have no rational point. We investigate versions of this over global function fields, focusing on a specific family of conics over F2(t)$\mathbb {F}_2(t)$ which illustrates new behavior.

Vector bundles on bielliptic surfaces: Ulrich bundles and degree of irrationality

open access: yesMathematische Nachrichten, EarlyView.
Abstract This paper deals with two problems about vector bundles on bielliptic surfaces. The first is to give a classification of Ulrich bundles on such surfaces S$S$, which depends on the topological type of S$S$. In doing so, we study the weak Brill–Noether property for moduli spaces of sheaves with isotropic Mukai vector. Adapting an idea of Moretti

Generalized quasi‐geostrophic equation in critical Lorentz–Besov spaces, based on maximal regularity

open access: yesMathematische Nachrichten, EarlyView.
Abstract We consider the quasi‐geostrophic equation with its principal part (−Δ)α${(-\mathrm{\Delta})^{\alpha}}$ for α>1/2$\alpha >1/2$ in Rn$\mathbb {R}^n$ with n≥2$n \ge 2$. We show that for every initial data θ0∈Ḃr,q1−2α+nr$\theta _0 \in \dot{B}^{1-2\alpha + \frac{n}{r}}_{r, q}$ with 1

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Analysis of a Mathematical Model of Marital Satisfaction

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A large number of marriages end in divorce. In this paper, we present a model for the emotional state of a couple based on bilinear ordinary differential equations. We study the effect of changes of each individual's self‐emotional state on the couple's state.

EKV-VBQ: Ensuring Verifiable Boolean Queries in Encrypted Key-Value Stores

open access: yesSensors
To address the deficiencies in privacy-preserving expressive query and verification mechanisms in outsourced key-value stores, we propose EKV-VBQ, a scheme designed to ensure verifiable Boolean queries over encrypted key-value data.

Growth of bilinear maps III: decidability

open access: yesTheoretical Computer Science
The following notion of growth rate can be seen as a generalization of joint spectral radius: Given a bilinear map $*:\mathbb R^d\times\mathbb R^d\to\mathbb R^d$ with nonnegative coefficients and a nonnegative vector $s\in\mathbb R^d$, denote by $g(n)$ the largest possible entry of a vector obtained by combining $n$ instances of $s$ using $n-1 ...
