SYM on quotients of spheres and complex projective spaces

open access: yesJournal of High Energy Physics, 2022
Abstract We introduce a generic procedure to reduce a supersymmetric Yang-Mills (SYM) theory along the Hopf fiber of squashed S2r−1 with U(1)r isometry, down to the ℂℙr−1 base. This amounts to fixing a Killing vector v generating a U(1) ⊂ U(1)r rotation and dimensionally reducing either along v or along another direction contained ...

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

open access: yesMolecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.

The eigenvalues of β-Laplacian of slant submanifolds in complex space forms

open access: yesAIMS Mathematics
In this paper, we provided various estimates of the first nonzero eigenvalue of the $ \beta $-Laplacian operator on closed orientated $ p $-dimensional slant submanifolds of a $ 2m $-dimensional complex space form $ \widetilde{\mathbb{V}}^{2m}(4\epsilon)

CP2 skyrmions and skyrmion crystals in realistic quantum magnets

open access: yesNature Communications, 2023
Magnetic skyrmions are nanoscale topological textures that have been recently observed in different families of quantum magnets. These objects are called CP1 skyrmions because they are built from dipoles—the target manifold is the 1D complex projective ...

Recent results on complex Cartan spaces [PDF]

open access: yes, 2015
In this paper, we first provide an updated survey of the geometry of complex Cartan spaces. New characterizations for some particular classes of complex Cartan spaces are pointed out, e.g. Landsberg-Cartan, strongly Berwald-Cartan and others. We introduce the Cartan-Randers spaces which offer examples of Berwald-Cartan and strongly Berwald-Cartan ...

Vertical inhibition of p110α/AKT and N‐cadherin enhances treatment efficacy in PIK3CA‐aberrated ovarian cancer cells

open access: yesMolecular Oncology, EarlyView.
PIK3CA amplification and PIK3CA mutation enhance ovarian tumorigenicity through an activation of AKT, which phosphorylates YAP at Ser127. This Ser127 phosphorylation leads to the retention of YAP in the cytoplasm and triggers RAC1 activity, promoting cell migration. Additionally, AKT activation increases expression of N‐cadherin, which further enhances

Differentials of the 2nd kind on a product surface

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
This paper deals with the problems of representing an arbitrary double differential of the second kind, defined on a surface which is the topological product of two curves, in terms of the products of simple differentials of the second kind on the two ...

OPTIMAL LINE PACKINGS FROM FINITE GROUP ACTIONS

open access: yesForum of Mathematics, Sigma, 2020
We provide a general program for finding nice arrangements of points in real or complex projective space from transitive actions of finite groups. In many cases, these arrangements are optimal in the sense of maximizing the minimum distance.

CYJAX: A package for Calabi-Yau metrics with JAX

open access: yesMachine Learning: Science and Technology, 2023
We present the first version of CYJAX, a package for machine learning Calabi–Yau metrics using JAX. It is meant to be accessible both as a top-level tool and as a library of modular functions.

Unraveling epigenetic heterogeneity across gastrointestinal adenocarcinomas through a standardized analytical framework

open access: yesMolecular Oncology, EarlyView.
This study shows that patients with gastrointestinal adenocarcinomas can be stratified into six distinct subtypes based on genome‐scale DNA methylation profiling. This stratification, achieved using a robust analytical framework, aligns with established tumor characteristics and holds potential to support prognostication.
