K-stability of Fano spherical varieties [PDF]
Annales scientifiques de l'École normale supérieure, 2020 We prove a criterion for K-stability of a $\mathbb{Q}$-Fano spherical variety with respect to equivariant special test configurations, in terms of its moment polytope and some combinatorial data associated to the open orbit. Combined with the equivariant version of the Yau-Tian-Donaldson conjecture for Fano manifolds proved by Datar and Sz kelyhidi ...

The variety of reductions for a reductive symmetric pair
, 2010 We define and study the variety of reductions for a reductive symmetric pair (G,theta), which is the natural compactification of the set of the Cartan subspaces of the symmetric pair.

Intelligent Stain‐Free Histology on Structural Colorimetric Nanocavities
Advanced Science, EarlyView.Chen and Gan et al. introduce a label‐free imaging platform using inexpensive Nanocavity‐on‐Silicon (NOS) slides. These slides transform subtle tissue variations into vivid structural colors, enabling high‐contrast histological imaging under a regular optical microscope. This stain‐free approach reveals morphological details comparable to traditional H&

Advanced Physics Research, EarlyView.The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

Epilepsia Open, EarlyView.Abstract Objective Telemedicine can improve access and continuity of care for people with epilepsy (PwE), but its adoption across Italian epilepsy centers remains inadequately characterized. We conducted a nationwide cross‐sectional survey of all 75 epilepsy centers certified by the Italian Chapter of the International League Against Epilepsy (Lega ...

Kawamata-Miyaoka-type inequality for $\mathbb Q$-Fano varieties with canonical singularities II: Terminal $\mathbb Q$-Fano threefolds [PDF]
Épijournal de Géométrie AlgébriqueWe prove an optimal Kawamata-Miyaoka-type inequality for terminal $\mathbb Q$-Fano threefolds with Fano index at least $3$. As an application, any terminal $\mathbb Q$-Fano threefold $X$ satisfies the following Kawamata-Miyaoka-type inequality \[ c_1(X ...

Examples violating Golyshev's canonical strip hypotheses
, 2018 We give the first examples of smooth Fano and Calabi-Yau varieties violating the (narrow) canonical strip hypothesis, which concerns the location of the roots of Hilbert polynomials of polarised varieties.

Long‐Range Exciton Energy Transfer in Two‐Dimensional Materials
Laser &Photonics Reviews, EarlyView.This review highlights recent advances in long‐range exciton energy transfer within planar 2D‐material architectures. It emphasizes the emergence of self‐hybridized excitonpolaritons, exciton coupling to surface plasmon polaritons and plasmonic lattices, and the role of dipoledipole transfer pathways in enabling efficient nanoscale energy transport ...
