American coot collective on-water dynamics [PDF]

open access: yes2013 Nonlinear Dynamics, Psychology, and Life Sciences, Vol. 17, No. 2, pp. 183-203, 2012
American coot (Fulica americana) flocks exhibit water surface (two-dimensional) collective dynamics that oscillate between two primary phases: a disordered phase of low density and non-uniform coot body orientations; a synchronized phase characterized by high density, uniform body orientations and speed.

The Turing Pattern Transition with the Growing Domain and Metabolic Rate Effects [PDF]

open access: yesarXiv
This study examines how patterns on mammal body surfaces change as they transition from juveniles to adults and with seasonal variations. Our previous research suggests that patterns formed in infancy may fade due to the growing domain effects, typically linked to the body's surface expanding as it grows, but this transition is influenced by various ...

A Quantum Model of Exaptation: Incorporating Potentiality into Evolutionary Theory [PDF]

open access: yesProgress in Biophysics & Molecular Biology, 113(1), 108-116, 2013
The phenomenon of preadaptation, or exaptation (wherein a trait that originally evolved to solve one problem is co-opted to solve a new problem) presents a formidable challenge to efforts to describe biological phenomena using a classical (Kolmogorovian) mathematical framework.

Heat stress conditions affect the social network structure of freeā€ranging sheep

open access: yesEcology and Evolution
Extreme weather conditions, like heatwave events, are becoming more frequent with climate change. Animals often modify their behaviour to cope with environmental changes and extremes.

Climate control in termite mounds: A review and new insights from X-ray tomography and flow field simulations [PDF]

open access: yesarXiv
Investigating the thermoregulation and ventilation processes in termite mound holds great interest, in particular for its potential implications in advancing eco-friendly building designs. In this article we discuss major results on these processes in termite mounds of varying sizes and ventilation types.

Analytical prediction of sub surface thermal history in translucent tissue phantoms during plasmonic photo thermotherapy [PDF]

open access: yesarXiv, 2015
Knowledge of thermal history in biological tissues during laser based hyperthermia is essential to achieve necrosis of tumour orcarcinoma cells. A semi analytical model to predict sub surface thermal history in translucent, soft, bio tissue mimics has been proposed. The model can accurately predict the spatio temporal temperature variations along depth

Functional regeneration strategies of hair follicles: advances and challenges

open access: yesStem Cell Research & Therapy
Hair follicles are essential appendages of human skin that function in protection, sensation, thermoregulation and social interactions. The multicellular components, particularly the dermal papilla, matrix and bulge housing stem cells, enable cyclic hair

Spatial roost networks and resource selection of female wild turkeys

open access: yesRoyal Society Open Science
Wildlife demography is influenced by behavioural decisions, with sleep being a crucial avian behaviour. Avian species use roost sites to minimize thermoregulation costs, predation risk and enhance foraging efficiency.
