Antideuteron Identification in Space with Helium Calorimeter
InstrumentsThe search for low-energy antideuterons in cosmic rays allows the addressing of fundamental physics problems testing for the presence of primordial antimatter and the nature of Dark Matter.

A single shot gamma-induced positron spectroscopy based on laser wakefield accelerator
AIP Advances, 2021 Single shot gamma-induced positron annihilation spectroscopy (GiPS) based on a laser wakefield accelerator is proposed. In this spectroscopy, a large number of gamma rays generated by laser-wakefield accelerated electrons are injected into a sample in a ...

Light-induced annihilation of Frenkel defects in organo-lead halide perovskites
, 2016 In spite of the unprecedented advances of organohalide lead perovskites in optoelectronic devices, many of the characteristics of this class of materials remain poorly understood.

The Unification Of The Intellect And The Intelligibe; Criticize And Analyze Haeri Yazdi's Viewpoint; Based on Jostarhaie Falsafi (Philosophical Queries) [PDF]
حکمت معاصر, 2014 The ‘argument of correlation’ is one of arguments by which Mulla-Sadra attempts to prove the unification of the intellect and the intelligible. Haeri Yazdi in some of his philosophical books has tried to explain the argument.

Advanced Functional Materials, EarlyView.This study presents a novel donor‐bridge‐acceptor‐bridge‐donor (D‐B‐A‐B‐D) molecular system, which shows near‐unity intramolecular excitation energy transfer (IET) from two identical energy donors to a coplanar acceptor. It enables a four‐level energy system for efficient lasing at the acceptor emission band in a microspherical cavity with a low lasing

The quintuplet annihilation spectrum
Journal of High Energy PhysicsAbstract We extend the Effective Field Theory of Heavy Dark Matter to arbitrary odd representations of SU(2) and incorporate the effects of bound states. This formalism is then deployed to compute the gamma-ray spectrum for a 5 of SU(2): quintuplet dark matter.

Contemplating annihilation [PDF]
BMJ, 2007 Humans are the only creatures capable of contemplating their own annihilation as a species; moreover, they do so with something akin to pleasure, to judge by the frisson that literary and cinematic annihilations usually evoke. For example, I once saw a film in the Teatro Municipal of Uyuni, on the Bolivian altiplano, in which giant spiders invaded the ...
