Risk of Retinopathy Associated with Long‐Term Use of Hydroxychloroquine in Patients with Rheumatic Diseases: A Systematic Review and Meta‐Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective We aimed to estimate the prevalence and cumulative incidence of hydroxychloroquine retinopathy (HCQ‐R) and its risk factors among patients receiving long‐term HCQ with rheumatic diseases through a systematic review and meta‐analysis of observational studies that used spectral‐domain optical coherence tomography (SD‐OCT) for screening ...

Hecke Groups, Dessins d'Enfants and the Archimedean Solids

open access: yesFrontiers in Physics, 2015
Grothendieck's dessins d'enfants arise with ever-increasing frequency in many areas of 21st century mathematical physics. In this paper, we review the connections between dessins and the theory of Hecke groups. Focussing on the restricted class of highly

Maximal subgroups of symmetric groups [PDF]

open access: yesTransactions of the American Mathematical Society, 1966
The cardinality of M shall be denoted by I MI. The support of s e S(M) is defined by spts={xeM:s(x)#x}. The fixed set of s=fs s={xeM:s(x)=x} = M-s spts.IfIMI = X > d,d < Y < X +,defineS(X,Y) ={scES(M): I spts |< Y}. The alternating subgroup shall be denoted A(X).

Ferroelectricity in Antiferromagnetic Wurtzite Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
We establish MnSiN2${\rm MnSiN}_2$ and MnGeN2${\rm MnGeN}_2$ as aristotypes of a new multiferroic wurtzite family that simultaneously exhibits ferroelectricity and antiferromagnetism with altermagnetic spin splitting. By strategically substituting alkaline‐earth metals, we predict new materials with coexisting switchable polarization, spin texture, and

Emergent Topological Magnons and Thermal Hall Effect in 2D Filling‐Enforced Fully Compensated Ferrimagnets

open access: yesAdvanced Functional Materials, EarlyView.
Schematic illustration of ferroelectric‐intercalation‐driven transitions in magnetic configurations and magnonic topological phases, together with the symmetry relations of magnonic Berry curvature. ABSTRACT Magnons in collinear magnets with vanishing net magnetization offer unique advantages for spin transport, including ultrafast dynamics and ...

On the depth of subgroups of simple groups

open access: yesForum of Mathematics, Sigma
The depth of a subgroup H of a finite group G is a positive integer defined with respect to the inclusion of the corresponding complex group algebras $\mathbb {C}H \subseteq \mathbb {C}G$ .

Chains of subgroups in symmetric groups

open access: yesJournal of Algebra, 1989
Eine Untergruppenkette der Länge m einer endlichen Gruppe G ist eine echt abnehmende Kette von Untergruppen \(G=G_ 0>G_ 1>...>G_ m=\{1\}\). Mit l(G) ist die maximale Länge einer Untergruppenkette von G bezeichnet. Verff. beweisen folgende Vermutung von \textit{L. Babai} [Commun.

Standardized Effect Measures Informing Next‐Generation Strategies for Mechanical Stimulation in Cartilage Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This systematic review quantitatively compares conventional mechanical stimulation strategies in cartilage tissue engineering across 85 heterogeneous in vitro studies. Applying standardized effect measures, meta‐analysis reveals that combined compression and shear loading optimally promotes cartilage matrix development.

Tetrastigma Hemsleyanum Polysaccharide Suppresses Triple‐Negative Breast Cancer by Disrupting the Hippo‐YAP/TEAD4‐PDIA4 Axis and Endoplasmic Reticulum Stress Adaptation

open access: yesAdvanced Science, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...
