Propagation properties of Airyprime pulses in relaxing nonlinear media

open access: yesOpen Physics
In recent years, Airyprime pulses have attracted much attention in the field of nonlinear optics due to their diffraction-free, self-accelerating, and self-healing properties, as well as their unique oscillating tail structure.

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.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

A common origin of all the species of high-energy cosmic rays? [PDF]

open access: yes, 1999
Cosmic ray nuclei, cosmic ray electrons with energy above a few GeV, and the diffuse gamma-ray background radiation (GBR) above a few MeV, presumed to be extragalactic, could all have their origin or residence in our galaxy and its halo.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The effect of dietary inclusions of guanidinoacetic acid on D1-42 broiler performance and processing yields

open access: yesJournal of Applied Poultry Research, 2020
Summary: Creatine is a central constituent in energy metabolism, especially in cells with variable energy demand, such as muscle cells. Animal proteins such as fish meal, poultry meal, and meat meal may provide adequate amounts of creatine when included ...

Measuring the yields and angular distributions of γ-quanta from the interaction between 14.1 MeV neutrons and sodium nuclei

open access: yesEurasian Journal of Physics and Functional Materials, 2021
A study of the reaction of inelastic scattering of 14.1 MeV neutrons by 23 Na nuclei was carried out at the TANGRA facility using the tagged neutron method. In this work, the energies of visible . transitions are determined, the yields of .

All-electron GW calculation for molecules: Ionization energy and electron affinity of conjugated molecules

open access: yes, 2010
An efficient all-electron G$^0$W$^0$ method and a quasiparticle selfconsistent GW (QSGW) method for molecules are proposed in the molecular orbital space with the full random phase approximation. The convergence with basis set is examined.

Magnetic energy harvesting and concentration at distance by transformation optics [PDF]

open access: yes, 2012
Magnetic energy is one the main agents powering our society: generating energy in power plants, keeping information in magnetic memories, moving our devices with motors. All of these applications require a certain spatial distribution of magnetic energy,
