The New Ephemeris and Light Curve Analysis of V870 Ara by the Ground-Based and TESS Data

Open Astronomy, 2021
New CCD photometric observations and their investigation of the W UMa-type binary, V870 Ara, are presented. Light curves of the system were taken through BVIfilters from the Congarinni Observatory in Australia.

Colour opponency is widespread across the mouse subcortical visual system and differentially targets GABAergic and non-GABAergic neurons

Scientific Reports, 2023
Colour vision plays many important roles in animal behaviour but the brain pathways processing colour remain surprisingly poorly understood, including in the most commonly used laboratory mammal, mice.

Regulation of mouse exploratory behaviour by irradiance and cone-opponent signals

BMC Biology, 2023
Background Animal survival depends on the ability to adjust behaviour according to environmental conditions. The circadian system plays a key role in this capability, with diel changes in the quantity (irradiance) and spectral content (‘colour’) of ...

Suprachiasmatic nucleus-dependent and independent outputs driving rhythmic activity in hypothalamic and thalamic neurons

BMC Biology, 2020
Background Daily variations in mammalian physiology are under control of a central clock in the suprachiasmatic nucleus (SCN). SCN timing signals are essential for coordinating cellular clocks and associated circadian variations in cell and tissue ...

Output from VIP cells of the mammalian central clock regulates daily physiological rhythms

Nature Communications, 2020
VIP-expressing neurons play a central role in circadian timekeeping within the mammalian central clock. Here the authors use opto- and chemogenetic approaches to show that VIP neuronal activity regulates rhythmic activity in downstream hypothalamic ...

Adipocyte NR1D1 dictates adipose tissue expansion during obesity

eLife, 2021
The circadian clock component NR1D1 (REVERBα) is considered a dominant regulator of lipid metabolism, with global Nr1d1 deletion driving dysregulation of white adipose tissue (WAT) lipogenesis and obesity.

Evaluating the effect of four unknown parameters included in a latitudinal energy balance model on the habitability of exoplanets

Open Astronomy, 2020
Among different models for determining the habitable zone (HZ) around a star, a Latitudinal Energy Balance Model (LEBM) is very beneficial due to its parametricity which keeps a good balance between complexity and simulation time.

PLRU Cache Domino Effects [PDF]

, 2006
Domino effects have been shown to hinder a tight prediction of worst case execution times (WCET) on real-time hardware. First investigated by Lundqvist and Stenström, domino effects caused by pipeline stalls were shows to exist in the PowerPC by ...

Brighter Time: A Smartphone App Recording Cognitive Task Performance and Illuminance in Everyday Life

Clocks & Sleep, 2022
Light is an influential regulator of behavioural and physiological state in mammals. Features of cognitive performance such as memory, vigilance and alertness can be altered by bright light exposure under laboratory and field conditions.

On Timing Model Extraction and Hierarchical Statistical Timing Analysis [PDF]

, 2013
In this paper, we investigate the challenges to apply Statistical Static Timing Analysis (SSTA) in hierarchical design flow, where modules supplied by IP vendors are used to hide design details for IP protection and to reduce the complexity of design and
