Primordial black holes and wormholes from domain wall networks
Physical Review DDomain walls (DWs) are topological defects originating from phase transitions in the early Universe. In the presence of an energy imbalance between distinct vacua, enclosed DW cavities shrink until the entire network disappears. By studying the dynamics of thin-shell bubbles in general relativity, we demonstrate that closed DWs with sizes exceeding the

Effect of Black Hole Attacks on Wireless Sensor Networks
International Journal of Advanced Research in Computer Science and Software Engineering, 2017 Wireless sensor networks (WSNs) establish a new popular of ambient supervision with many latent packages. The environment of wireless sensor networks prone to different forms of attacks as networks are prepared in open and unsecured surroundings. This paper analyses the overall performance of AODV whilst attacked by black hole, through varying the ...

Parameter estimates in binary black hole collisions using neural networks [PDF]
General Relativity and Gravitation, 2016 We present an algorithm based on artificial neural networks (ANNs), that estimates the mass ratio in a binary black hole collision out of given Gravitational Wave (GW) strains. In this analysis, the ANN is trained with a sample of GW signals generated with numerical simulations.

Advanced Functional Materials, EarlyView.Janus (MoS2) transistors functionalized with sodium alginate (SA) and poly(vinylidene fluoride‐co‐trifluoroethylene) [P(VDF‐TrFE)] exhibit persistent photo‐induced ionic gating, driven by dynamic cation migration at the hybrid interface. This ionic mechanism enables finely tunable photoconductivity and emulates key synaptic plasticity behaviors ...
