Diffuse Emission of Galactic High-energy Neutrinos from a Global Fit of Cosmic Rays
The Astrophysical Journal, 2023 In the standard picture of Galactic cosmic rays, a diffuse flux of high-energy gamma rays and neutrinos is produced from inelastic collisions of cosmic-ray nuclei with the interstellar gas.

Opening Remarks ~ Prospects of very high energy cosmic ray interactions for astroparticle physics [PDF]
EPJ Web of Conferences, 2019 Hadronic interactions of very high energy cosmic rays have been studied in various aspects of motivation. In recent decades, mainly motivated by air shower experiments, modelling of very high energy cosmic ray interactions have been greatly improved ...

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 ...

Advanced Functional Materials, EarlyView.Walnut seeds are enclosed in a remarkably strong shell made of sclerenchyma, separated by a pectin‐rich suture tissue. Different cell shapes and chemical composition of this tissue point to an opening mechanism, which is triggered by cyclic humidity changes.

Advanced Functional Materials, EarlyView.High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

ПРОБЛЕМА ПРОИСХОЖДЕНИЯ КОСМИЧЕСКИХ ЛУЧЕЙ СВЕРХВЫСОКИХ ЭНЕРГИЙ
Odessa Astronomical Publications, 2011 The problem of cosmic ray origin comes to two main questions: were and how cosmic particles are accelerated up to very high energies. In this paper, arguments in favor of two basic sources of cosmic rays (Galaxy and Metagalaxy) are considered and ...

Advanced Functional Materials, EarlyView.This work proposes a dual‐surface reaction strategy to optimize the interfacial contacts in organic–inorganic photodetectors. 1,4,5,8,9,11‐hexaazatriphenylene hexacarbonitrile (HAT‐CN) and ytterbium layers are designed to react with the Si surface, thus minimizing noise.
