Quantum Resonances and Ratchets in Free-Falling Frames
, 2007 Quantum resonance (QR) is defined in the free-falling frame of the quantum kicked particle subjected to gravity. The general QR conditions are derived. They imply the rationality of the gravity parameter $\eta$, the kicking-period parameter $\tau /(2\pi)$

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

White Deaths Exceed Births in One-Third of U.S. States [PDF]
, 2016 In this brief, authors Rogelio Sáenz and Kenneth Johnson report that there were more white deaths than births in seventeen states in 2014, compared to just four states in 2004. This is the highest number of states with white natural decrease (more deaths

A quantum trampoline for ultra-cold atoms
, 2009 We have observed the interferometric suspension of a free-falling Bose-Einstein condensate periodically submitted to multiple-order diffraction by a vertical 1D standing wave.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Agriscientia, 2009 Sprouting or germination in wheat takes place as a result of the rupture of the dormancy in grain, expressed in physiological terms as the increase of α-amylases and proteases activity, which has been associated with low values of falling number ...

Can the standard impact tests become a true materials evaluation tool? [PDF]
, 2016 Impact resistance constitutes one of the most popular quality control tools for polymeric materials and plastic finished parts. There are a number of standard impact test methods devoted to evaluate the impact response of polymeric materials (e.g ...

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.
