ABSTRACT The northern European distal cryptotephra framework is constantly developing both in terms of identification of new tephra horizons and improved age constraints for the already well‐established tephra marker horizons. However, many prehistoric tephra layers have only been dated by the radiocarbon method, with its inherent problems.

THE SOMATOTOPY OF THE SPINAL CORD: A COMPREHENSIVE DESCRIPTION. [PDF]
For the benefit of medical students, in this paper we examine the somatotopic organization of the spinal cord, which shows a similar organization in mammalians. The dorsal horn is comprised of sensory nuclei with deutoneurons; the lateral horn contains

Astrophysical Neutrino Event Rates and Sensitivity for Neutrino Telescopes [PDF]
Spectacular processes in astrophysical sites produce high-energy cosmic rays which are further accelerated by Fermi-shocks into a power-law spectrum. These, in passing through radiation fields and matter, produce neutrinos.

ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by a preclinical stage that typically lasts for decades. Early on during this time, microglia react to pathological changes and become protective and even transiently delay neurodegeneration.

The lifetime of cosmic rays in the Milky Way [PDF]
The most reliable method to estimate the residence time of cosmic rays in the Galaxy is based on the study of the suppression, due to decay, of the flux of unstable nuclei such as beryllium-10, that have lifetime of appropriate duration.
