Stable Topologies of Event Horizon [PDF]

open access: yes, 1997
In our previous work, it was shown that the topology of an event horizon (EH) is determined by the past endpoints of the EH. A torus EH (the collision of two EH) is caused by the two-dimensional (one-dimensional) set of the endpoints.

Leaf Eh and pH: A Novel Indicator of Plant Stress. Spatial, Temporal and Genotypic Variability in Rice (Oryza sativa L.) [PDF]

open access: yes, 2019
A wealth of knowledge has been published in the last decade on redox regulations in plants. However, these works remained largely at cellular and organelle levels. Simple indicators of oxidative stress at the plant level are still missing. We developed a

Alterations in vascular function in primary aldosteronism - a cardiovascular magnetic resonance imaging study [PDF]

open access: yes, 2014
Introduction: Excess aldosterone is associated with increased cardiovascular risk. Aldosterone has a permissive effect on vascular fibrosis. Cardiovascular magnetic resonance imaging (CMR) allows study of vascular function by measuring aortic ...

Topological Appearance of Event Horizon: What Is the Topology of the Event Horizon That We Can See? [PDF]

open access: yes, 1997
The topology of the event horizon (TOEH) is usually believed to be a sphere. Nevertheless, some numerical simulations of gravitational collapse with a toroidal event horizon or the collision of event horizons are reported.

Transmit Power Minimization for Wireless Networks with Energy Harvesting Relays

open access: yes, 2016
Energy harvesting (EH) has recently emerged as a key technology for green communications as it can power wireless networks with renewable energy sources. However, directly replacing the conventional non-EH transmitters by EH nodes will be a challenge. In
