Probing dark matter annihilation in the Galaxy with antiprotons and gamma rays [PDF]
, 2017 A possible hint of dark matter annihilation has been found in Cuoco, Korsmeier and Krämer (2017) from an analysis of recent cosmic-ray antiproton data from AMS-02 and taking into account cosmic-ray propagation uncertainties by fitting at the same time ...

Exciton–Exciton Annihilation Is Coherently Suppressed in H-Aggregates, but Not in J-Aggregates [PDF]
Journal of Physical Chemistry Letters, 2017 We theoretically demonstrate a strong dependence of the annihilation rate between (singlet) excitons on the sign of dipole–dipole couplings between molecules.

Photonic Engineering Enables All‐Passive Upconversion Imaging with Low‐Intensity Near‐Infrared Light
Advanced Functional Materials, EarlyView.A passive upconversion imaging system enables the observation of scenes illuminated by low‐intensity incoherent near‐infrared light from 750 to 930 nm, by converting it into the visible without the use of external power. The upconverter is enabled by triplet–triplet annihilation in a bulk heterojunction, with absorption enhanced by plasmonic resonators

Sebuah Analisis Terhadap Problematika Ajaran Restorasi Berkaitan Dengan Konsep Bumi Baru
Dunamis: Jurnal Teologi dan Pendidikan Kristiani, 2018 Abstraks. The second coming of Christ is an event inalienable to mankind. In addition to declaring punishment for unbelievers, His second coming also fulfils the presence of a new heaven and earth in which the righteous will reign with Christ forever. Of

Solar atmospheric neutrinos and the sensitivity floor for solar dark matter annihilation searches [PDF]
, 2017 Cosmic rays interacting in the solar atmosphere produce showers that result in a flux of high-energy neutrinos from the Sun. These form an irreducible background to indirect solar WIMP self-annihilation searches, which look for heavy dark matter ...

Reconfigurable 3D Magnetic Nanoarchitectures
Advanced Functional Materials, EarlyView.This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...

Физика волновых процессов и радиотехнические системы, 2014 The reasons of angular photon distribution occurrence at electron-positron annihilation are considered. It is shown, that angular photon distribution is consequence of Dopplers effect in the reference frame of the electron and positron mass center.

Relativistic dark matter at the Galactic center
, 2007 In a large region of the supersymmetry parameter space, the annihilation cross section for neutralino dark matter is strongly dependent on the relative velocity of the incoming particles.

Advanced Functional Materials, EarlyView.It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Search for right-handed neutrinos from dark matter annihilation with gamma-rays [PDF]
, 2017 Several extensions of the Standard Model contain right-handed (sterile) neutrinos in the GeV-TeV mass range. Due to their mixing with the active neutrinos, they may give rise to novel effects in cosmology, neutrino physics, and collider searches.
