Abstract Objective Cerebrospinal fluid (CSF) over-drainage is an unintended sequela of using a shunt valve to treat hydrocephalus, and a second valve may be added in series to better control drainage. In this study, we t...

Abstract Accurate measurements of Earth gravity and its variations with time are crucial not only for fundamental research on gravitation in physics, but also for other scientific areas including Earth sciences, geophysi...

Abstract The exploration of the surrounding world and the universe is an important theme in the legacy of humankind. The detection of gravitational waves is adding a new dimension to this grand effort. What are the funda...

Abstract The non-conservation of the energy-momentum tensor in f(R, T) gravity can be interpreted as an effective manifestation of dissipation. Motivated by this, we propose a new formulation of f(R, T) gravity based o...

Abstract We explore a cosmological framework in which a Gauss–Bonnet (GB) coupled scalar field, acting as dark energy, interacts with a fermionic dark matter field through a coupling obtained from the point of view of ...

Este artículo propone ordenar el campo político argentino en torno a dos clivajes. El primero está representado por el clásico izquierda y derecha, el segundo por el peronismo y la posición antiperonista o “gorila...

Abstract Simulating the response of granular materials under realistic loading scenarios is essential for ensuring the reliability of geotechnical infrastructure. This task is particularly challenging because natural soi...

Brief periods of extreme gravitational transition are anticipated during interplanetary spaceflight, including transitions between microgravity, hypogravity, and hypergravity. Rapid sensorimotor adaptation will occur fol...

We present a multiwavelength analysis of the nearby millisecond pulsar PSR J0437–4715, combining Hubble Space Telescope (HST) far-ultraviolet, ROSAT soft X-ray, and XMM-Newton X-ray data, to model its broadband emissio...

Context. Astronomical environments are governed by a complex interplay of physical processes, including gravitational dynamics, radiative transfer, stellar evolution, chemistry, and hydrodynamics. These processes span a ...

Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregula...

We have derived and summarized and most important atmospheric temperature lapse rates. ALRs essentially govern vertical atmospheric air stability and creation of some cloud types. The sensitivity analysis of various atmo...

We study a topological phase transition in spacetime through which the early universe evolved, growing exponentially due to quantum fluctuations of gravity, described as a geometric quantum field with a noncommutative, n...

Visually monitoring of the residual morphology and quantitatively determining the degradation degree of hydrogels applied in tissue repair therapy in a real-time and noninvasive manner were a crucial technological mean. ...

Abstract Optically trapped silica nanoparticles are a promising tool for precise sensing of gravitational or inertial forces and fundamental physics, including tests of quantum mechanics at “large” mass scales. This ...

In this paper, the model of radial motion of dusty matter for the spherically symmetric case in General Relativity (GR) was developed. The model can be used, in particular, to describe galactic halos of dark matter. The ...

Abstract Active tectonics and coastal deformation predispose continental margins to submarine gravitational instability and canyon head retreat. Here we investigate the drivers of this susceptibility along the Italian co...

The secular approximation of the hierarchical three body systems has been proven to be very useful in addressing many astrophysical systems, from planets to stars to black holes. In such a system, two objects are on a ti...

IntroductionHuman space exploration is progressing into an unprecedented era characterized by extended-duration missions, the establishment of permanent lunar bases, and planned crewed voyages to Mars. These activities i...

We present high-spatial-resolution (≲1 $\mathop{.}\limits{^{\prime\prime} }$ 0), multiwavelength observations of UGC 2369S, a nearby luminous infrared galaxy showing three distinct cores separated on kiloparsec scales ...

This book is based on the lecture notes of the course on black hole astrophysicsgiven at the University of La Plata, Argentina, by one of us (GER). The materialaims at advanced undergraduate and graduate students with in...

Los autores desarrollaron un detallado perfil del Mercosur, a partir de sus ejes centrales (desde antecedentes, gravitación económica, características principales del proceso de transición y de la unión Aduanera, co...

Most studies of ontogeny in anurans focus on the premetamorphic and adult stages, but very few have focused on the postmetamorphic and juvenile stages. Juvenile frogs share the same environment as adult frogs. They are e...
