The Mandelstam--Leibbrandt Prescription and the Discretized Light Front Quantization [PDF]
, 1994 It is shown that the quantization of the unphysical degrees of freedom, which leads to the Mandelstam--Leibbrandt prescription for the infrared spurious singularities in the continuum light cone gauge, does indeed suggest some quite natural recipe to ...

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.

Natural light exposure, sleep and depression among day workers and shiftworkers at arctic and equatorial latitudes. [PDF]
PLoS One, 2015 Objectives This study aimed to investigate the relationship between individual natural light exposure, sleep need, and depression at two latitudes, one extreme with a few hours of light per day during winter, and the other with equal hours of light and ...

A Note on Zipf's Law, Natural Languages, and Noncoding DNA regions [PDF]
, 1995 In Phys. Rev. Letters (73:2, 5 Dec. 94), Mantegna et al. conclude on the basis of Zipf rank frequency data that noncoding DNA sequence regions are more like natural languages than coding regions. We argue on the contrary that an empirical fit to Zipf's ``

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Natural light as a determinant of the identity of architectural space
Journal of Architecture and Urbanism, 2014 In this study, the effect of natural light on the architectural space quality was examined. Contribution of natural light in three different dimensions as the readability of the space, the effect of the space, and its aesthetical evaluation was taken ...

The Role of Daylight for Humans: Gaps in Current Knowledge
Clocks & Sleep, 2020 Daylight stems solely from direct, scattered and reflected sunlight, and undergoes dynamic changes in irradiance and spectral power composition due to latitude, time of day, time of year and the nature of the physical environment (reflections, buildings ...

An endogenous crepuscular rhythm of rainbow trout (Salmo gairdneri) photomechanical movements [PDF]
, 1982 1. The position of the epithelial pigment and cones in the retina of Salmo gairdneri was determined during extended periods of darkness in fish entrained to both artificial and natural light/dark cycles. 2. An endogenous rhythm of such photomechanical
