On a Class of α-Para Kenmotsu Manifolds [PDF]

Mediterranean Journal of Mathematics, 2014
The purpose of this paper is to classify $\alpha$-para Kenmotsu manifolds $M^3$ such that the projection of the image of concircular curvature tensor $L$ in one-dimensional linear subspace of $T_{p}(M^{3})$ generated by $\xi_{p}$ is zero.

On connections with torsion on nonholonomic para-Kenmotsu manifolds

Дифференциальная геометрия многообразий фигур, 2023
The concept of a nonholonomic para-Kenmotsu manifold is intro­duced. A nonholonomic para-Kenmotsu manifold is a natural generaliza­tion of a para-Kenmotsu manifold; the distribution of a nonholonomic para-Kenmotsu manifold does not need to be involutive.

Geometry of conformal η-Ricci solitons and conformal η-Ricci almost solitons on paracontact geometry

Open Mathematics, 2022
We prove that if an η\eta -Einstein para-Kenmotsu manifold admits a conformal η\eta -Ricci soliton then it is Einstein. Next, we proved that a para-Kenmotsu metric as a conformal η\eta -Ricci soliton is Einstein if its potential vector field VV is ...

Liquid biopsy detects genomic drivers in NSCLC without EGFR mutations by single‐plex testing: WJOG13620L

Cancer Medicine, Volume 12, Issue 23, Page 21097-21110, December 2023., 2023
Alterations in pre‐defined nine genes were detected in 21 NSCLC patients by multiplex gene analysis. Abstract Background Actionable tumor genomic alterations, primarily EGFR mutations, occur in nearly 70% of Japanese advanced nonsquamous non‐small cell lung cancer (NSCLC) patients.

Human resources for administrative work to carry out a comprehensive genomic profiling test in Japan

Cancer Science, Volume 114, Issue 7, Page 3041-3049, July 2023., 2023
We sent a questionnaire to government‐designated Cancer Genomic Medicine Hospitals in Japan. For every comprehensive genomic profiling (CGP) test, 7.6 h of administrative work was needed, with an estimated labor cost of ¥78,071/test. Streamlining the administrative work for CGP tests and subsidies are necessary for expansion of CGP testing.

Dataset complexity impacts both MOTU delimitation and biodiversity estimates in eukaryotic 18S rRNA metabarcoding studies

Environmental DNA, Volume 4, Issue 2, Page 363-384, March 2022., 2022
We assessed how the choice of bioinformatics algorithm (UCLUST, VSearch, DADA2, and Deblur) impacts the downstream biological conclusions that are drawn from eukaryotic 18S rRNA metabarcoding studies by using a low‐complexity and high‐complexity dataset. ASV algorithms produce more biologically realistic metabarcoding outputs, with DADA2 being the most

Predictive value of EGFR mutation in non–small‐cell lung cancer patients treated with platinum doublet postoperative chemotherapy

Cancer Science, Volume 113, Issue 1, Page 287-296, January 2022., 2022
Mutation status of stage II‐III Ns‐NSCLC (n = 389) was analyzed using targeted deep sequencing. Patients with an EGFR mutation‐positive status had a significantly shorter recurrence‐free survival (RFS). Both the pathological stage and EGFR mutation status were independent prognostic factors for RFS. Abstract The mutation status of tumor tissue DNA (n =

ρ‐Einstein Solitons on Warped Product Manifolds and Applications

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
The purpose of this research is to investigate how a ρ‐Einstein soliton structure on a warped product manifold affects its base and fiber factor manifolds. Firstly, the pertinent properties of ρ‐Einstein solitons are provided. Secondly, numerous necessary and sufficient conditions of a ρ‐Einstein soliton warped product manifold to make its factor ρ ...

Some New Results on Trans‐Sasakian Manifolds

Journal of Mathematics, Volume 2022, Issue 1, 2022., 2022
In this paper, we classify trans‐Sasakian manifolds which are realized as real hypersurfaces in a complex space form. We also investigate trans‐Sasakian manifolds whose Reeb vector fields are harmonic‐Killing. The above results bring some new characterizations for the property of trans‐Sasakian 3‐manifolds.
