Creation of the universe with a stealth scalar field

, 2012
The stealth scalar field is a non-trivial configuration without any back-reaction to geometry, which is characteristic for non-minimally coupled scalar fields. Studying the creation probability of the de Sitter universe with a stealth scalar field by the

Drug‐Free Thrombolysis Mediated by Physically Activated Micro/Nanoparticles

Advanced Functional Materials, EarlyView.
Overview of particle‐mediated thrombolytic effects (thermal, mechanical, and chemical) and their activating physical stimuli (light, ultrasound, and magnetic field) in drug‐free thrombolysis. ABSTRACT Thrombus‐associated disorders rank among the world's leading causes of death, with ischemic heart disease and stroke as the main contributors.

Massive stealth scalar fields from field redefinition method

, 2018
We propose an uni-parametric deformation method of action principles of scalar fields coupled to gravity which generates new models with massive stealth field configurations, i.e. with vanishing energy-momentum tensor.

AdS black holes with arbitrary scalar coupling [PDF]

, 2013
A general class of axionic and electrically charged black holes for a self-interacting scalar field nonminimally coupled to Einstein gravity with a negative cosmological constant is presented. These solutions are the first examples of black holes with an

Evaluating the Antiviral Efficacy of Encapsulated PKC Inhibitor BIM‐I against influenza A Virus Infection

Advanced Healthcare Materials, EarlyView.
This study explores nanoparticle delivery of the protein kinase C inhibitor bisindolylmaleimide‐I (BIM‐I) to combat influenza A virus infections. Encapsulation in biodegradable PLGA nanoparticles improved safety while maintaining the compound's strong antiviral activity.

Cusp Phased Metasurfaces for Wideband RCS Reduction Under Broad Angles of Incidence

IEEE Open Journal of Antennas and Propagation
This article presents an efficient and effective design approach of the phase distribution calculation across metasurface for significant radar cross section (RCS) reduction of a circular polarization (CP) and liner polarization (LP) radar waves. The RCS

Stealth Acceleration and Modified Gravity

, 2007
We show how to construct consistent braneworld models which exhibit late time acceleration. Unlike self-acceleration, which has a de Sitter vacuum state, our models have the standard Minkowski vacuum and accelerate only in the presence of matter, which ...
