Spatial and temporal variability in cyanobacterial populations controlled by physical processes [PDF]
Journal of Plankton Research, 2004 The Fitzroy impoundment is a long slender water body (10 m deep) formed by the regulation of the Fitzroy River in tropical Australia. Large, monsoonally driven discharges in late summer flush the impoundment repeatedly leaving, after 2 months, a longitudinally uniform, well-mixed water column, rich in dissolved nutrients and with high turbidity.

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Metacommunity composition of web-spiders in a fragmented neotropical forest: relative importance of environmental and spatial effects. [PDF]
PLoS ONE, 2012 The distribution of beta diversity is shaped by factors linked to environmental and spatial control. The relative importance of both processes in structuring spider metacommunities has not yet been investigated in the Atlantic Forest.

Urban Intersection Signal Control Based on Time-Space Resource Scheduling
IEEE Access, 2021 This paper improves the level of urban traffic control by creasing the dimension of control variables. It focuses on roads rather than vehicles. A new space-time resource scheduling model and a bi-level optimization control method for urban intersections

Comparative approaches for assessing access to alcohol outlets: exploring the utility of a gravity potential approach. [PDF]
, 2016 BackgroundA growing body of research recommends controlling alcohol availability to reduce harm. Various common approaches, however, provide dramatically different pictures of the physical availability of alcohol.

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 ...

Multi‐UAV cooperative trajectory optimisation for a multi‐hop UAV relaying network
Electronics Letters, 2021 In this letter, an unmanned aerial vehicle (UAV) assisted data collection scenario is considered in the Internet of Things (IoT), where a multi‐hop UAV relaying network is constructed for real‐time data transmission.

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 ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand
FEBS Letters, EarlyView.Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
