The TRISTAN Antarctic Cosmic Ray detector. [PDF]

Proceedings of 36th International Cosmic Ray Conference — PoS(ICRC2019), 2019
TRISTAN detector is part of a new family of high accuracy multitracking capabilities. TRISTAN was designed to be installed at the Spanish Antartic Base in Livignston Island, as one of the dectectors of ORCA (Antarctic Cosmic Ray Observaroty). It will be complemented by a neutron monitor and a muon telescope with the purpose of mesuring cosmic rays at ...

Geant4 Simulations of a Scintillator Cosmic-Ray Detector

Applied Sciences
Reliable cosmic-ray measurements require a thorough understanding of the detector used. It is especially important when detectors are very simple like the scintillator detectors considered in this work, which provide only information about the amplitude ...

Understanding the Phase Reversals of Galactic Cosmic-Ray Anisotropies

The Astrophysical Journal, 2022
Energy spectra and anisotropies are very important probes of the origin of cosmic rays. Recent measurements show that complicated but very interesting structures exist at similar energies in both the spectra and energy-dependent anisotropies, indicating ...

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

Advanced 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.

The Performance of CRTNT Fluorescence Light Detector for Sub-EeV Cosmic Ray Observation

, 2006
Cosmic Ray Tau Neutrino Telescopes (CRTNT) using for sub-EeV cosmic ray measurement is discussed. Performances of a stereoscope configuration with a tower of those telescopes plus two side-triggers are studied.

Prospects for radio detection of ultra-high energy cosmic rays and neutrinos [PDF]

, 2004
The origin and nature of the highest energy cosmic ray events is currently the subject of intense investigation by giant air shower arrays and fluorescent detectors. These particles reach energies well beyond what can be achieved in ground-based particle

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

Advanced 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 ...

Radio detection of cosmic rays in the Pierre Auger Observatory

, 2009
In small-scale experiments such as CODALEMA and LOPES, radio detection of cosmic rays has demonstrated its potential as a technique for cosmic ray measurements up to the highest energies. Radio detection promises measurements with high duty-cycle, allows

Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...
