Harmonic Maps and Stability on f-Kenmotsu Manifolds

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
The purpose of this paper is to study some submanifolds and Riemannian submersions on an f-Kenmotsu manifold. The stability of a ϕ-holomorphic map from a compact f-Kenmotsu manifold to a Kählerian manifold is proven.

A new curvature-like tensor in an almost contact Riemannian manifold

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2016
In a M. Prvanović’s paper [5], we can find a new curvature-like tensor in an almost Hermitian manifold.In this paper, we define a new curvature-like tensor, named contact holomorphic Riemannian, briefly (CHR), curvature tensor in an almost ...

Optimization of Soliton Structures Using Lifting Theory on Tangent Bundles of Statistical Kenmotsu Manifolds

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
This paper investigates the optimization of soliton structures on tangent bundles of statistical Kenmotsu manifolds through lifting theory. By constructing lifted statistical Kenmotsu structures using semisymmetric metric and nonmetric connections, we derive explicit expressions for the curvature tensor, Ricci operator, and scalar curvature. We analyze

Desensitizing Effect of Intra‐Tumoral GDF‐15 on Immunotherapy in Patients With Advanced Non‐Small Cell Lung Cancer

open access: yesThoracic Cancer, Volume 16, Issue 10, May 2025.
Intra‐tumoral GDF‐15 expression was assessed in advanced NSCLC patients receiving PD‐1/PD‐L1 monotherapy. GDF‐15 high levels were strongly associated with cancer cachexia and significantly poorer clinical outcomes, suggesting its potential as a predictive biomarker for immunotherapy efficacy.

Almost Kenmotsu 3-h-manifolds with transversely Killing-type Ricci operators

open access: yesOpen Mathematics, 2020
In this paper, it is proved that the Ricci operator of an almost Kenmotsu 3-h-manifold M is of transversely Killing-type if and only if M is locally isometric to the hyperbolic 3-space ℍ3(−1){{\mathbb{H}}}^{3}(-1) or a non-unimodular Lie group endowed ...

Harmonic (p, q)‐Curves in Trans‐Sasakian and Normal Almost Paracontact Metric Manifolds

open access: yesJournal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we give some characterizations about biharmonic, f‐harmonic, and f‐biharmonic (p, q)‐curves in 3‐dimensional trans‐Sasakian and normal almost paracontact metric manifolds. The (p, q)‐curves are considered as generalizations of magnetic curves.

A Note on Doubly Warped Product Contact CR-Submanifolds in trans-Sasakian Manifolds

open access: yes, 2007
Warped product CR-submanifolds in Kaehlerian manifolds were intensively studied only since 2001 after the impulse given by B.Y. Chen. Immediately after, another line of research, similar to that concerning Sasakian geometry as the odd dimensional version

Suitability of frozen cell pellets from cytology specimens for the Amoy 9‐in‐1 assay in patients with non‐small cell lung cancer

open access: yesThoracic Cancer, Volume 15, Issue 21, Page 1665-1672, July 2024.
We retrospectively evaluated the performance of frozen cell pellets from cytology specimens (FCPs) in the Amoy 9‐in‐1 assay. The success rates of DNA and RNA analyses were both 100% in Amoy 9‐in‐1 assay, compared with 86% and 45%, using NGS assay. Although the coverage of Amoy 9‐in‐1 is limited compared to NGS assays, the Amoy using FCPs can be a ...
