On Killing vector fields on a tangent bundle with g-natural metric Part I [PDF]

, 2014
The tangent bundle of a Riemannian manifold (M, g) with a non-degenerate g− natural metric G that admits a Killing vector field is investigated. Using Taylor’s formula (TM,G) is decomposed into four classes.

Triple‐Negative Breast Cancer Cells Utilize IL8 and CXCL1 to Suppress NK Cells’ Function and Facilitate Cancer Metastasis

Advanced Science, EarlyView.
Triple‐negative breast cancer (TNBC) cells evade natural killer (NK) cell immunity by secreting IL8 and CXCL1. These chemokines suppress NK cells’ function via CXCR1/2 and enhance cancer cells’ survival through PD‐L1 upregulation and BCL‐2 anti‐apoptotic signaling.

Generalized supergravity equations for the WZW model

Physics Letters B
Generalized supergravity equations (GSEs) were originally proposed as a modification of the standard IIB supergravity equations to satisfy the background of η-deformed AdS5×S5 introduced by Arutyunov et al.

PANX2 Suppresses Lung Adenocarcinoma Progression by Inducing Disulfidptosis and Enhancing Antitumor Immunity

Advanced Science, EarlyView.
ABSTRACT Lung adenocarcinoma (LUAD) remains a leading cause of cancer mortality with limited therapeutic options. Disulfidptosis, a novel cell death modality driven by disulfide stress, represents a promising target, yet its regulation in LUAD is poorly defined. Here, we identify Pannexin 2 (PANX2) as a tumor suppressor in LUAD.

A study on killing vector fields in four-dimensional spaces [PDF]

, 2019
In the present study, some properties of Killing vector fields are investigated on 4-dimensional manifolds in case of the signature of the metric tensor 1 is either Lorentz or positive definite or neutral. First of all, the notation and the main

*-Ricci soliton on (κ, μ)′-almost Kenmotsu manifolds

Open Mathematics, 2019
Let (M, g) be a non-Kenmotsu (κ, μ)′-almost Kenmotsu manifold of dimension 2n + 1. In this paper, we prove that if the metric g of M is a *-Ricci soliton, then either M is locally isometric to the product ℍn+1(−4)×ℝn or the potential vector field is ...

Certain results on Kenmotsu manifolds

Cumhuriyet Science Journal, 2020
In this paper, we focus on Kenmotsu manifolds. Firstly, we investigate almost quasi Ricci symmetric Kenmotsu manifolds. Then, we study Kenmotsu manifold admitting a Yamabe soliton. We find that if the soliton field of the Yamabe soliton is orthogonal to

Lactoferrin Deficiency During Lactation Causes Adult Obesity‐Related Metabolic Disease Through Persistent Adipose Dysfunction Driven by Impaired Adipocyte Development

Advanced Science, EarlyView.
Lactational lactoferrin deficiency exerts lasting effects on epididymal adipose tissue development from lactation into adulthood: it impairs adipocyte hyperplasia and induces pathological hypertrophy, resulting in lower body weight yet exacerbated metabolic dysfunction under a high‐fat diet in adulthood.
