The second will be first: competition on directed networks [PDF]
, 2015 Multiple sinks competition is investigated for a walker diffusing on directed complex networks. The asymmetry of the imposed spatial support makes the system non transitive.

Field-control, phase-transitions, and life's emergence [PDF]
, 2012 Instances of critical-like characteristics in living systems at each organizational level as well as the spontaneous emergence of computation (Langton), indicate the relevance of self-organized criticality (SOC).

Interplay between the morphometry of the lungs and the mode of locomotion in birds and mammals
Biological Research, 2007 We studied the lung diffusion parameters of two species of birds and two species of mammals to explore how structural and functional features may be paralleled by differences in life style or phylogenetic origin.

The Single-Breath Diffusing Capacity of CO and NO in Healthy Children of European Descent
PLoS ONE, 2014 Rationale The diffusing capacity (DL) of the lung can be divided into two components: the diffusing capacity of the alveolar membrane (Dm) and the pulmonary capillary volume (Vc).

Optimal villi density for maximal oxygen uptake in the human placenta
, 2015 We present a stream-tube model of oxygen exchange inside a human placenta functional unit (a placentone). The effect of villi density on oxygen transfer efficiency is assessed by numerically solving the diffusion-convection equation in a 2D+1D geometry ...

Flexible couplings: diffusing neuromodulators and adaptive robotics [PDF]
, 2005 Recent years have seen the discovery of freely diffusing gaseous neurotransmitters, such as nitric oxide (NO), in biological nervous systems. A type of artificial neural network (ANN) inspired by such gaseous signaling, the GasNet, has previously been ...

Inflammation associated with lung function abnormalities in COVID-19 survivors
BMC Pulmonary Medicine, 2023 Background Activation of inflammatory pathways promotes organ dysfunction in COVID-19. Currently, there are reports describing lung function abnormalities in COVID-19 survivors; however, the biological mechanisms remain unknown. The aim of this study was

Value of lung diffusing capacity for nitric oxide in systemic sclerosis
Physiological Reports, 2019 A decreased lung diffusing capacity for carbon monoxide (DLCO) in systemic sclerosis (SSc) is considered to reflect losses of alveolar membrane diffusive conductance for CO (DMCO), due to interstitial lung disease, and/or pulmonary capillary blood volume
