Neutrinos and Cosmic Rays Observed by IceCube [PDF]

open access: yes, 2017
The core mission of the IceCube Neutrino observatory is to study the origin and propagation of cosmic rays. IceCube, with its surface component IceTop, observes multiple signatures to accomplish this mission.

Opening Remarks ~ Prospects of very high energy cosmic ray interactions for astroparticle physics [PDF]

open access: yesEPJ 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 ...

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

Cosmic Ray Propagation: Nonlinear Diffusion Parallel and Perpendicular to Mean Magnetic Field

open access: yes, 2007
We consider the propagation of cosmic rays in turbulent magnetic fields. We use the models of magnetohydrodynamic turbulence that were tested in numerical simulations, in which the turbulence is injected on large scale and cascades to small scales.

Are gamma-ray bursts the sources of ultra-high energy cosmic rays? [PDF]

open access: yes, 2014
We reconsider the possibility that gamma-ray bursts (GRBs) are the sources of the ultra-high energy cosmic rays (UHECRs) within the internal shock model, assuming a pure proton composition of the UHECRs.

Simulation Study of Optical Band Radiation during the Afterglow Phase of Gamma-Ray Bursts Based on the HADAR Experiment

open access: yesThe Astrophysical Journal
Studying the afterglow of gamma-ray bursts (GRBs) is essential for refining theoretical models, uncovering their underlying physical processes, and exploring potential new physics. Multiwavelength investigations have emerged as a fundamental approach for

Atmospheric effects of stellar cosmic rays on Earth-like exoplanets orbiting M-dwarfs [PDF]

open access: yes, 2015
M-dwarf stars are generally considered favourable for rocky planet detection. However, such planets may be subject to extreme conditions due to possible high stellar activity.

Proteins, Processing, and Properties of Adhesive Fluid Condensates Purified from Mussels

open access: yesAdvanced Functional Materials, EarlyView.
Mussels exhibit an unmatched proficiency for adhering to wet surfaces in salty environments—a remarkable ability that could inspire new biomedical and technical glues. The fluid protein condensates used to form the underwater mussel glue are extracted, reconstituted and characterized with advanced spectroscopy and nanomechanical analysis, revealing ...

ПРОБЛЕМА ПРОИСХОЖДЕНИЯ КОСМИЧЕСКИХ ЛУЧЕЙ СВЕРХВЫСОКИХ ЭНЕРГИЙ

open access: yesOdessa 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 ...
