Doubly Special Relativity with a minimum speed and the Uncertainty Principle

open access: yes, 2017
The present work aims to search for an implementation of a new symmetry in the space-time by introducing the idea of an invariant minimum speed scale ($V$).

On the spherically symmetric Einstein-Yang-Mills-Higgs equations in Bondi coordinates

open access: yes, 2012
We revisit and generalize, to the Einstein-Yang-Mills-Higgs system, previous results of D. Christodoulou and D. Chae concerning global solutions for the Einstein-scalar field and the Einstein-Maxwell-Higgs equations.

Sasaki-Einstein and paraSasaki-Einstein metrics from (\kappa,\mu)-structures [PDF]

open access: yes, 2013
We prove that any non-Sasakian contact metric (\kappa,\mu)-space admits a canonical \eta-Einstein Sasakian or \eta-Einstein paraSasakian metric. An explicit expression for the curvature tensor fields of those metrics is given and we find the values of ...

On‐treatment dynamics of circulating extracellular vesicles in the first‐line setting of patients with advanced non‐small cell lung cancer: the LEXOVE prospective study

open access: yesMolecular Oncology, EarlyView.
The LEXOVE prospective study evaluated plasma cell‐free extracellular vesicle (cfEV) dynamics using Bradford assay and dynamic light scattering in metastatic non‐small cell lung cancer patients undergoing first‐line treatments, correlating a ∆cfEV < 20% with improved median progression‐free survival in responders versus non‐responders.

Einstein and Tagore, Newton and Blake, Everett and Bohr: the dual nature of reality [PDF]

open access: yes, 2012
There are two broad opposing classes of attitudes to reality (realist vs idealist, material vs mental) with corresponding attitudes to knowledge (objective vs subjective, scientific vs romantic).

Geodesic-Einstein metrics and nonlinear stabilities

open access: yes, 2018
In this paper, we introduce notions of nonlinear stabilities for a relative ample line bundle over a holomorphic fibration and define the notion of a geodesic-Einstein metric on this line bundle, which generalize the classical stabilities and Hermitian ...

Liraglutide for idiopathic intracranial hypertension: a real‐world propensity score‐matched study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objective Idiopathic intracranial hypertension (IIH) is a neurological disorder predominantly affecting young women with obesity, characterized by elevated intracranial pressure. While current treatments include weight loss counseling, medical therapies, and surgical interventions, their limitations necessitate exploring novel therapeutic ...

Can we distinguish between black holes and wormholes by their Einstein-ring systems?

open access: yes, 2012
For the last decade, the gravitational lensing in the strong gravitational field has been studied eagerly. It is well known that, for the lensing by a black hole, infinite number of Einstein rings are formed by the light rays which wind around the black ...

Smart Rubber Extrusion Line Combining Multiple Sensor Techniques for AI‐Based Process Control

open access: yesAdvanced Engineering Materials, EarlyView.
This publication presents a digitalization approach for a laboratory rubber extrusion line, employing innovative measurement methods and artificial intelligence (AI)‐based process control. The results demonstrate that the measurement systems are capable of detecting changes in the process and extrudate quality.

Einstein's Paradox [PDF]

open access: yesNature, 1922
IN his review of Bergson's new book (NATURE, October 14) Prof. Wildon Carr refers to “Einstein's paradox,” which he quotes in inverted commas as follows:—“Suppose a traveller to be enclosed in a cannon-ball and projected from the earth with a velocity amounting to a twenty-thousandth of the velocity of light; suppose him to meet a star and be returned ...
