Sterile neutrino dark matter: impact of active-neutrino opacities

Journal of High Energy Physics, 2020
The resonant production of keV sterile-neutrino dark matter mainly takes place during the QCD epoch of the early universe. It has been argued that it could be strongly affected by the opacities (or damping rates) of active neutrinos, which receive non ...

Dynamischer Austausch von Bindemolekülen steigert die Effizienz der Proteinmarkierung in DNA‐PAINT um das bis zu 15‐Fache

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Der dynamische Austausch von Bindemolekülen (Dynamic Binder Exchange; DyBE) nutzt transiente Binde–Zielprotein‐Interaktionen, um die Markierungseffizienz in der superauflösenden Mikroskopie um das 15‐Fache zu steigern. DyBE kartiert die Organisation von Rezeptor‐Tyrosinkinasen (RTKs), einschließlich HER2‐Homodimere und EGFR–HER2‐Heterodimere, auf der ...

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

Isolated proton bunch acceleration by a petawatt laser pulse

Nature Communications, 2018
Monoenergetic proton beams can be useful in many applications but their generation from laser irradiation of targets is challenging. Here the authors demonstrate a laser-accelerated proton bunch with improved density and energy resolution by using a ...

The physical properties of candidate neutrino-emitter blazars [PDF]

EPJ Web of Conferences
High-energy neutrinos detected by the IceCube Observatory provide a unique opportunity to study the origin of cosmic rays and the nature of the sources producing them.

Equation of state and speed of sound of isospin-asymmetric QCD on the lattice

Journal of High Energy Physics, 2023
We determine the QCD equation of state at nonzero temperature in the presence of an isospin asymmetry between the light quark chemical potentials on the lattice. Our simulations employ N f = 2 + 1 flavors of dynamical staggered quarks at physical masses,

Pikosekunden‐Stabilisierung von übertragenen Ladungsträgern an plasmonischen Metall‐Molekül‐Grenzflächen

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Ladungs‐ und Wärmeübertragungsprozesse zwischen plasmonischen Nanopartikeln und adsorbierten molekularen Monoschichten werden mittels ultraschneller Infrarotspektroskopie beobachtet. Die Analyse der Absorption freier Ladungsträger und der Schwingungssignale zeigt, dass überlaufende Ladungsträger stabilisiert werden, wodurch sich ihre Lebensdauer auf ...

The chiral separation effect from lattice QCD at the physical point

Journal of High Energy Physics
In this paper we study the Chiral Separation Effect by means of first-principles lattice QCD simulations. For the first time in the literature, we determine the continuum limit of the associated conductivity using 2+1 flavors of dynamical staggered ...

Niedrig dosierte Ganzhaut‐Elektronenbestrahlung bei erythrodermatischer Mycosis fungoides und Sézary‐Syndrom: Ergebnisse aus der prospektiven S‐MISR‐Studie

JDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 23, Issue 12, Page 1534-1543, December 2025.
Zusammenfassung Hintergrund Bei der erythrodermatischen Mycosis fungoides (eMF) und dem Sézary‐Syndrom (SS) sind systemische Therapien häufig mit verzögerten und nicht anhaltenden klinischen Remissionen verbunden. Patienten und Methodik 35 Patienten mit eMF und SS wurden mittels Ganzhautelektronenbestrahlung (total skin electron beam therapy, TSEBT ...

On the absence of the chiral magnetic effect in equilibrium QCD

Journal of High Energy Physics
In this paper we investigate the chiral magnetic effect (CME): the generation of an electric current due to a homogeneous background magnetic field and a homogeneous chiral imbalance in QCD.
