Cosmogenic neutrinos and gamma-rays and the redshift evolution of UHECR sources
If ultra-high-energy cosmic rays (UHECRs) have extragalactic origins, as is widely assumed to be the case at least for the majority of cosmic rays with energies above a few EeV, secondary neutrinos and photons can be expected to be produced during the ...

What's New? Serrated polyposis syndrome has been associated with an increased risk of colorectal cancer. HIC1 is a tumor suppressor gene commonly silenced in serrated polyps and several cancers. This study suggests HIC1 as a novel germline predisposition factor to serrated polyposis syndrome, with variants altering gene transcriptional regulation and ...

New generation Cherenkov telescope array: HADAR and its performance introduction
Astrophysical very high energy (VHE) gamma-rays are believed to result almost exclusively from the interactions of populations of highly relativistic particles with ambient matter or photon fields.

Nuclei Measurements with the Alpha Magnetic Spectrometer on the International Space Station
The exact behavior of nuclei fluxes in cosmic rays and how they relate to each other is important for understanding the production, acceleration and propagation mechanisms of charged cosmic rays.

An innovative method for noninvasive melanoma diagnosis using the attenuation coefficient from OCT scans and machine learning has been proposed, supporting small sample sizes. When combined with Raman spectroscopy, it can further enhance accuracy. ABSTRACT A multimodal method comprising optical imaging using OCT and molecular detection using Raman ...

Planck Neutrinos as Ultra High Energy Cosmic Rays
The studied conjecture is that ultra high energy cosmic rays (UHECRs) are hypothetical Planck neutrinos arising in the decay of the protons falling onto the gravastar.

Cosmic Rays: What Gamma Rays Can Say [PDF]
We will review the main channels of gamma ray emission due to the acceleration and propagation of cosmic rays, discussing the cases of both galactic and extra-galactic cosmic rays and their connection with gamma rays observations.

Abstract The high mountains of Taiwan provide a unique location for Quaternary palaeoclimate research in East Asia and the north‐western Pacific. This study applies geomorphological field mapping and rock surface exposure dating with paired (10Be/26Al) in situ‐produced terrestrial cosmogenic nuclides to identify and date glacial landforms and boulders ...
