Phase information in cosmological collider signals

Journal of High Energy Physics, 2022
Massive particles produced during the cosmic inflation can imprint in the primordial non-Gaussianities as characteristic oscillating functions of various momentum ratios, known as cosmological collider signals.

Engineering the Link: From Genome Interaction Maps to Functional Insight

Advanced Biology, EarlyView.
Advances in chromosome conformation capture have revealed the genome's 3D organization, yet its causal impact on gene regulation remains elusive. This review highlights emerging genome‐engineering tools ‐ zinc fingers, TALEs, and CRISPR‐Cas9 ‐ that enable targeted manipulation of chromatin loops to dissect structure–function relationships. It discusses

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Neutrino-antineutrino asymmetry of CνB on the surface of the round Earth

Journal of High Energy Physics
It has been claimed that the coherent scattering of relic neutrinos with the Earth will result in a neutrino-antineutrino asymmetry of O $$ \mathcal{O} $$ (10−4) on the Earth surface, which is five orders of magnitude larger than the naive model ...

A Different Perspective on the Solid Lubrication Performance of Black Phosphorus: Friend or Foe?

Advanced Engineering Materials, EarlyView.
Researchers investigate black phosphorus (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Measuring inflaton couplings via primordial gravitational waves

Journal of High Energy Physics, 2023
We investigate the reach of future gravitational wave (GW) detectors in probing inflaton couplings with visible sector particles that can either be bosonic or fermionic in nature.

Machine Learning Applied to High Entropy Alloys under Irradiation

Advanced Engineering Materials, EarlyView.
Designing alloys for extreme environments demands fast, trustworthy prediction. This review charts how machine learning—especially machine‐learned interatomic potentials and predictive models based on experiment‐informed datasets—captures the complexity of high‐entropy alloys in extreme environments, predicts phase formation, mechanical properties, and

X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.
