Pressure dependence of the charge-density-wave gap in rare-earth tri-tellurides
, 2006 We investigate the pressure dependence of the optical properties of CeTe$_3$, which exhibits an incommensurate charge-density-wave (CDW) state already at 300 K.

FEBS Letters, EarlyView.Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Redox reactions in subducted CaCO3–Fe–SiO2 as a potential source of superdeep diamond inclusions
Scientific ReportsCaCO3 is one of the most abundant carbonates at the Earth’s surface. It is transported into the mantle in substantial quantities via subducted slabs and participates in the deep mantle carbon cycle along with other mantle materials.

CALCULATION OF SEISMICALLY LOADED EARTH RETAINING STRUCTURES
Acta Polytechnica CTU Proceedings, 2022 Eurocode 1998-5 for the design of earth retaining structures in seismic conditions describes calculations using the Mononobe-Okabe method. This simplified quasi-static procedure is to some extent very conservative.

Measuring the cosmic ray acceleration efficiency of a supernova remnant [PDF]
, 2009 Cosmic rays are the most energetic particles arriving at earth. Although most of them are thought to be accelerated by supernova remnants, the details of the acceleration process and its efficiency are not well determined.

Time after time – circadian clocks through the lens of oscillator theory
FEBS Letters, EarlyView.Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Spin crossover in ferropericlase from first-principles molecular dynamics
, 2015 Ferropericlase, (Mg,Fe)O, is the second-most abundant mineral of the Earth's lower mantle. With increasing pressure, the Fe ions in the material begin to collapse from a magnetic to non-magnetic spin state.

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.
