A decomposition theorem for $\mathbb{Q}$-Fano Kähler–Einstein varieties
Comptes Rendus. MathématiqueLet $X$ be a $\mathbb{Q}$-Fano variety admitting a Kähler–Einstein metric. We prove that up to a finite quasi-étale cover, $X$ splits isometrically as a product of Kähler–Einstein $\mathbb{Q}$-Fano varieties whose tangent sheaf is stable with respect to ...

Discrete Wilson Lines in F-Theory
Advances in High Energy Physics, 2011 F-theory models are constructed where the 7 -brane has a nontrivial fundamental group. The base manifolds used are a toric Fano variety and a smooth toric threefold coming from a reflexive polyhedron.

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 Székelyhidi, it

Advanced Science, EarlyView.A protocol of fs‐laser‐induced periodic phase‐transition of 2D‐MoTe2 template, inducing AuNPs@1T’‐MoTe2 nanograting, is developed. The labeled AuNPs@1T’‐MoTe2 substrate conjugated with specialized immunoglobulin G demonstrates an unexpectedly high discrimination accuracy close to unity for serological diagnosis of rheumatoid arthritis by frequency ...

Gorenstein spherical Fano varieties
, 2015 We obtain a combinatorial description of Gorenstein spherical Fano varieties in terms of certain polytopes, generalizing the combinatorial description of Gorenstein toric Fano varieties by reflexive polytopes and its extension to Gorenstein horospherical

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy
Advanced Science, EarlyView.ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

Super-rigid affine Fano varieties [PDF]
Compositio Mathematica, 2018 We study a wide class of affine varieties, which we call affine Fano varieties. By analogy with birationally super-rigid Fano varieties, we define super-rigidity for affine Fano varieties, and provide many examples and non-examples of super-rigid affine Fano varieties.
