Gravitomagnetism in modified theory of gravity [PDF]
International Journal of Modern Physics D, 2019 We study the gravitomagnetism in the Scalar-Vector-Tensor theory or Moffat’s Modified theory of Gravity (MOG). We compute the gravitomagnetic field that a slow-moving mass distribution produces in its Newtonian regime. We report that the consistency between the MOG gravitomagnetic field and that predicted by the Einstein’s gravitational theory and ...

Lemaître-Tolman-Bondi static universe in Rastall-like gravity
Nuclear Physics B, 2020 In this work, we try to obtain a stable Lemaître-Tolman-Bondi (LTB) static universe, which is spherically symmetric and radially inhomogeneous. However, this is not an easy task, and fails in general relativity (GR) and various modified gravity theories,

, 2013 The recent observational data in cosmology seem to indicate that the universe is currently expanding in an accelerated way. An intriguing interpretation of these data is that they may just be signalling that Einstein's General Relativity is not the correct description of gravity when we consider distances of the order of the present horizon of the ...

Mass screening in modified gravity
Classical and Quantum Gravity, 2008 Models of modified gravity introduce extra degrees of freedom, which for consistency with the data, should be suppressed at observable scales. In the models that share properties of massive gravity such a suppression is due to nonlinear interactions: An isolated massive astrophysical object creates a halo of a nonzero curvature around it, shielding its

Advanced Healthcare Materials, EarlyView.This study introduces a modular microfluidic platform that connects liver cells with live microbes to mimic key aspects of the gut–liver interaction in steatosis. Using this system, both microbial metabolites and live bacteria significantly reduced fat accumulation in liver cells, but live microbes triggered inflammation and broader metabolic changes ...

Portable Molecularly Imprinted Polymer Sensor for Rapid Swab‐Based Detection of Norovirus
Advanced Healthcare Materials, EarlyView.This work reports a rapid, portable smartphone‐based sensor capable of detecting four norovirus genotypes from swab samples within 15 min. Sensor selectivity was validated through evaluation against four common live viruses. The swab‐based sampling process enabled simple sample preparation combined with the compact detection system, supporting use of ...
