Energy and Momentum of Oscillating Neutrinos [PDF]

open access: yesMod.Phys.Lett.A16:2363,2001, 2001
It is shown that Lorentz invariance implies that in general flavor neutrinos in oscillation experiments are superpositions of massive neutrinos with different energies and different momenta. It is also shown that for each process in which neutrinos are produced there is either a Lorentz frame in which all massive neutrinos have the same energy or a ...

Progress in international collaboration on EXFOR library [PDF]

open access: yesEPJ Web of Conferences, 2020
The EXFOR library has served as the unique repository of experimental cross section and other nuclear reaction data for 50 years. The Nuclear Reaction Data Centres (NRDC) have compiled data sets from more than 22000 experimental works for the EXFOR ...

Deeply x-raying the high-energy sky [PDF]

open access: yes, 2016
All-sky explorations by Fermi-LAT have revolutionized our view of the gamma-ray sky. While its ongoing all-sky survey counts thousands of sources, essential issues related to the nature of unassociated sources call for sensitive all-sky surveys at hard X-ray energies that allow for their identification.

An Economically Viable 100% Renewable Energy System for All Energy Sectors of Germany in 2030

open access: yesEnergies, 2021
To be able to fulfil the Paris Climate Agreement and keep global warming with reasonable confidence at a maximum of 1.5 °C above pre-industrial levels, Germany must set an end to all greenhouse gas emissions by 2030.

Examining the Viability of Phantom Dark Energy [PDF]

open access: yesPhys. Rev. D 92, 063019 (2015), 2015
In the standard cosmological framework of the 0th-order FLRW metric and the use of perfect fluids in the stress-energy tensor, dark energy with an equation-of-state parameter $w < -1$ (known as phantom dark energy) implies negative kinetic energy and vacuum instability when modeled as a scalar field.

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

open access: yesFEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Parameter Evaluation Procedure for Gapped Core Current Transformers Considering Accuracy Requirements under Transient Conditions [PDF]

open access: yesE3S Web of Conferences, 2020
Particular features of gapped core current transformers and characteristics of transient phenomena inside them are under consideration; a procedure is proposed that allows for evaluating the excitation limiting e.m.f.
