Convergence of the Yamabe flow on manifolds with minimal boundary [PDF]

ANNALI SCUOLA NORMALE SUPERIORE - CLASSE DI SCIENZE, 2016
We study the Yamabe flow on compact Riemannian manifolds of dimensions greater than two with minimal boundary. Convergence to a metric with constant scalar curvature and minimal boundary is established in dimensions up to seven, and in any dimensions if ...

A Longitudinal Case Study of Renal Cyst Progression and Regression in Trisomy 13

Clinical Case Reports, Volume 13, Issue 9, September 2025.
Multiple T2‐weighted high‐signal‐intensity structures were observed in both kidneys accompanied by bilateral renal enlargement in a male neonate with trisomy 13. ABSTRACT Trisomy 13 is a chromosomal disorder frequently associated with congenital anomalies, including polycystic kidney disease (PKD).

Contrast‐Enhanced Computed Tomography/Magnetic Resonance Imaging Is Useful for Surveying Gastroesophageal Varices in Patients After Fontan Surgery

Hepatology Research, Volume 55, Issue 9, Page 1320-1326, September 2025.
The presence of gastroesophageal varices (GEVs) following Fontan surgery (FS) could not be predicted by blood biochemical indices and other clinical factors, and contrast‐enhanced CT or MRI can be useful for surveying GEVs in patients following FS. ABSTRACT Objectives Liver cirrhosis (LC) is a common complication of Fontan surgery (FS) because of the ...

The association between additional radiotherapy after systemic chemotherapy and the prognosis of stage FIGO 2018 IVB cervical cancer

International Journal of Gynecology &Obstetrics, Volume 170, Issue 2, Page 908-915, August 2025.
Abstract Objective Systemic platinum‐based chemotherapy is the first‐line treatment of choice for metastatic cervical cancer. While subsequent radiotherapy after primary chemotherapy is a potential option, its benefit remains unclear. This multicenter retrospective study aimed to evaluate whether post‐chemotherapy radiotherapy improves the prognosis of

Gap Theorems for Locally Conformally Flat Manifolds [PDF]

, 2015
In this paper, we prove a gap result for a locally conformally flat complete non-compact Riemannian manifold with bounded non-negative Ricci curvature and a scalar curvature average condition.

Comprehensive Safety Assessment of Hydrogen: From Production to Application in Energy Systems

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
In the quest for sustainable and clean energy alternatives to fossil fuels, hydrogen emerges as a front‐runner due to its high energy yield and environmentally friendly combustion byproduct, water. This study delves into the comprehensive lifecycle of hydrogen energy, from its production through various methods, storage, and transportation, to its ...

Riemann Solitons on Homogeneous Siklos Spacetimes

Journal of Mathematics, Volume 2025, Issue 1, 2025.
In this paper, we investigate the properties of Riemann solitons on homogeneous Siklos spacetimes. Siklos spacetimes, which are special solutions to Einstein’s equations with a wave‐like potential, provide a suitable setting for studying the geometric properties of Riemann solitons.
