Visceral-to-subcutaneous fat ratio is a time-stable predictor of survival and toxicity in advanced hepatocellular carcinoma

Abstract Purpose Nutritional status significantly impacts the prognosis of patients with hepatocellular carcinoma (HCC). Computed tomography (CT) has become a key tool for assessing body composition (BC), with abnormal patterns increasingly linked to reduced survival. However, BC...

Does an Unconventional Source with a High Silica Content (Obsidian) or a High Alumina Content (Bauxite) Affect the Type of Potassium Zeolite Formation? Preliminary Data on Synthetic Products’ Efficiency in Ammonium Removal

In this paper, obsidian (OS) and bauxite (BX) are used to synthesize zeolites via KOH prefusion, followed by a conventional hydrothermal process (HY) or an unconventional vapor-phase crystallization method (VPC) at 90 °C. The results indicate that, due to their chemical and miner...

Acoustic Vases in Europe: A Review of Documentation, Approaches, Measurement Methodologies, and Preliminary Proposal for a Methodological Framework

Research on acoustic vases embedded in historical buildings has progressively developed through archaeology, architectural history, and acoustics, producing extensive documentation on their distribution, geometry, installation and possible acoustic role, with experimental evidenc...

Controlled-rail brachistochrones in non-stationary spacetimes: conformal symmetry, Kodama energy, and Vaidya dynamics

What is the fastest constrained worldline in a spacetime that is itself evolving? In a stationary spacetime the relativistic brachistochrone reduces to Fermat/Randers optics with a conserved rail energy supplied by a timelike Killing vector; in a dynamical spacetime no such conse...

hp Analysis of Nitsche’s method for Maxwell’s problem using a stabilised finite element formulation

Abstract The paper presents an hp analysis of Nitsche’s method applied to Maxwell’s problem using a stabilised finite element (FE) formulation. While the FE formulation and the weak imposition of Dirichlet boundary conditions have been previously explored, the novelty of this wor...
