A Semi‐Discrete Lagrangian‐Eulerian Numerical Scheme for Diffusive‐Dispersive Conservation Laws With Discontinuous Coefficient

open access: yesNumerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

A theorem of differential mappings of Riemann surfaces

open access: yesInternational 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.

Genus two modular bootstrap

open access: yesJournal of High Energy Physics, 2019
We study the Virasoro conformal block decomposition of the genus two partition function of a two-dimensional CFT by expanding around a ℤ3-invariant Riemann surface that is a three-fold cover of the Riemann sphere branched at four points, and explore ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, Volume 16, Issue 8, Page 1563-1592, August 2026.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

The super period matrix with Ramond punctures in the supergravity formulation

open access: yesNuclear Physics B, 2015
In a very recent preprint, Witten showed how to construct a g|r×g|r super period matrix for super Riemann surfaces of genus g with 2r Ramond punctures, which is symmetric in the Z2 graded sense.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Kernel function and integral representations on Klein surfaces

open access: yesElectronic Journal of Differential Equations, 2017
Some representation theorems for the solutions of the Dirichlet problem and the Neumann problem on Klein surfaces are proved by using an analogue of the harmonic kernel function on symmetric Riemann surfaces.

Deformaciones isométricas infinitesimales de una clase de superficies pegadas

open access: yesRevista de Matemática: Teoría y Aplicaciones, 2009
In this work the sufficient condition of rigidity of a stuck 4-dimensional surface in the Euclidean 6-dimensional space is demonstrated. This surface represents in himself, the product of Riemann of two surfaces, each one of which it is in the Euclidean ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

open access: yesEnergy Science &Engineering, Volume 14, Issue 8, Page 3697-3725, August 2026.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Teichmüller Theory of Bordered Surfaces

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
We propose the graph description of Teichmüller theory of surfaces with marked points on boundary components (bordered surfaces). Introducing new parameters, we formulate this theory in terms of hyperbolic geometry.
