N $$ \mathcal{N} $$ = (2, 2) AdS3 from D3-branes wrapped on Riemann surfaces

Journal of High Energy Physics, 2022
We construct N $$ \mathcal{N} $$ = (2, 2) supersymmetric AdS3 solutions of type IIB supergravity, dual to twisted compactifications of 4d N $$ \mathcal{N} $$ = 4 super-Yang-Mills on Riemann surfaces.

Monitoring of water volume in a porous reservoir using seismic data: Validation of a numerical model with a field experiment

Near Surface Geophysics, Volume 24, Issue 2, Page 110-127, April 2026.
Abstract As global groundwater levels continue to decline rapidly, there is a growing need for advanced techniques to monitor and manage aquifers effectively. This study focuses on validating a numerical model using seismic data from a small‐scale experimental setup designed to estimate water volume in a porous reservoir.

Fubini–Study forms on punctured Riemann surfaces

Comptes Rendus. Mathématique
In this paper we consider a punctured Riemann surface endowed with a Hermitian metric that equals the Poincaré metric near the punctures, and a holomorphic line bundle that polarizes the metric. We show that the quotient of the induced Fubini–Study forms

Sleep in Functional Motor Disorders: A Case–Control Polysomnographic Study

Journal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Sleep problems are frequent in functional motor disorders (FMDs). Surprisingly, objective correlates of impaired sleep and its relationship to other comorbidities have been understudied, and no polysomnographic study is available. We aimed to map the polysomnographic parameters in the context of self‐reported sleep and mood symptoms and search

Riemann surfaces with a quasi large abelian group of automorphisms

Le Matematiche, 2011
In this work we classify all Riemann surfaces having a quasi large abelian group of automorphisms, i.e. having an abelian group of automorphisms of order strictly bigger than 2(g−1), where g denotes the genus of the Riemann surface.

Ratios of Extinction Coefficient, Mass, and Surface Area to Backscatter Coefficient and Mass to Extinction Coefficient Derived From Balloon‐Borne Stratospheric Aerosol Size Distribution Measurements From 1989–2025

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract In situ measurements of stratospheric aerosol are the only measurements that provide sufficient detail to determine aerosol number, size, surface area, volume/mass, and effective radius; however, these measurements are limited in space and time.

Systèmes dynamiques algébriquement complètement intégrables et géométrie

Annals of the West University of Timisoara: Mathematics and Computer Science, 2015
In this paper I present the basic ideas and properties of the complex algebraic completely integrable dynamical systems. These are integrable systems whose trajectories are straight line motions on complex algebraic tori (abelian varieties). We make, via

Human Systems Immunology in the Omics Era: Challenges, Methods, and Emerging Directions

European Journal of Immunology, Volume 56, Issue 3, March 2026.
Systems immunology provides a transformative framework for decoding human immune complexity. This review evaluates high‐throughput technologies and provides a roadmap for navigating analytical challenges—such as batch effects and interindividual heterogeneity—to successfully translate multimodal data into meaningful biological insights.

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

Mathematische Nachrichten, Volume 299, Issue 3, Page 514-528, March 2026.
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

A theorem of differential mappings of Riemann surfaces

International Journal of Mathematics and Mathematical Sciences, 1994
In this paper, we have extended S.S. Chern's second basic theorem about holomorphic mapping between two Riemann surfaces to more general case, and also obtained two similar results.
