Journal of Biological Dynamics, 2021 Pest control based on an economic threshold (ET) can effectively prevent excessive pest control measures such as pesticide abuse and overharvesting. The instinctive dispersal of pest populations in biological network patches for better survival poses ...

A mixed incoherent feed-forward loop allows conditional regulation of response dynamics. [PDF]
PLoS ONE, 2014 Expression of the SodA superoxide dismutase (MnSOD) in Escherichia coli is regulated by superoxide concentration through the SoxRS system and also by Fur (Ferric uptake regulator) through a mixed incoherent feed forward loop (FFL) containing the RyhB ...

Control of beam propagation in optically written waveguides beyond the paraxial approximation
, 2013 Beam propagation beyond the paraxial approximation is studied in an optically written waveguide structure. The waveguide structure that leads to diffractionless light propagation, is imprinted on a medium consisting of a five-level atomic vapor driven by

Modernization of the Irkutsk Incoherent Scatter Radar
Solar-Terrestrial Physics, 2017 We present the results of modernization of the Irkutsk Incoherent Scatter Radar’s control and acquisition system. The modernization was carried out using results of space experiments Plasma–Progress and Radar–Progress involving Progress cargo spacecraft.

Shaping migration at the border: the entangled rationalities of border control practices
Comparative Migration Studies, 2021 This article analyses how border guards as members of a state organisation shape the movement of non-nationals into the territory of a nation state. Based on ethnographic fieldwork on the Swiss Border Guard (SBG), it explores the rationalities—understood

Dark-State Polaritons in Single- and Double-$\Lambda$ Media
, 2008 We derive the properties of polaritons in single-$\Lambda$ and double-$\Lambda$ media using a microscopic equation-of-motion technique. In each case, the polaritonic dispersion relation and composition arise from a matrix eigenvalue problem for arbitrary

Demonstration of controlled spatial incoherence for beam smoothing
Optics ExpressA concept for beam smoothing of high-energy laser systems is demonstrated. Multiple coherent beams are multiplexed so that their incoherent mix decreases the far-field nonuniformity after random spatial phase modulation introduced by a phase plate. Modeling shows that the incoherent mix effectively leads to the expected scaling in terms of the number ...

Modeling Incoherent Discourse in Non-Affective Psychosis
Frontiers in Psychiatry, 2020 BackgroundComputational linguistic methodology allows quantification of speech abnormalities in non-affective psychosis. For this patient group, incoherent speech has long been described as a symptom of formal thought disorder.
