The vertical distribution and biological transport of marine microplastics across the epipelagic and mesopelagic water column. [PDF]
Sci Rep, 2019 Plastic waste has been documented in nearly all types of marine environments and has been found in species spanning all levels of marine food webs. Within these marine environments, deep pelagic waters encompass the largest ecosystems on Earth. We lack a

The impact of temporal sampling resolution on parameter inference for biological transport models. [PDF]
PLoS Comput Biol, 2018 Imaging data has become an essential tool to explore key biological questions at various scales, for example the motile behaviour of bacteria or the transport of mRNA, and it has the potential to transform our understanding of important transport ...

Transport through Biological Membranes [PDF]
Annual Review of Physiology, 1953 In the following we shall use the term “membrane” in a purely pragmatic sense: A sheet of unstirred material, separating two well stirred solutions. What unifies the concept of membrane is its physical function as a barrier as well as the methods by which such structures can be studied (Ussing, Erlij and Lassen, 1974). Thus a capillary wall or a kidney

Optimisation of Biological Transport Networks
East Asian Journal on Applied Mathematics, 2022 . Transport networks such as blood vessel systems and leaf venation are uni-versally required for large-size living organisms in order to overcome the low efficiency of the diffusion in large scale mass transportation.

Effects of jamming on non-equilibrium transport times in nano-channels [PDF]
Phys. Rev. Lett. 103, 128103 (2009), 2009 Many biological channels perform highly selective transport without direct input of metabolic energy and without transitions from a 'closed' to an 'open' state during transport. Mechanisms of selectivity of such channels serve as an inspiration for creation of artificial nano-molecular sorting devices and bio-sensors.

How the asymmetry of internal potential influences the shape of I-V characteristic of nanochannels [PDF]
, 2006 Ion transport in biological and synthetic nanochannels is characterized by such phenomena as ion current fluctuations, rectification, and pumping. Recently, it has been shown that the nanofabricated synthetic pores could be considered as analogous to biological channels with respect to their transport characteristics \cite{Apel, Siwy}.

Effects of multiple occupancy and inter-particle interactions on selective transport through narrow channels: theory versus experiment [PDF]
, 2008 Many biological and artificial transport channels function without direct input of metabolic energy during a transport event and without structural rearrangements involving transitions from a 'closed' to an 'open' state. Nevertheless, such channels are able to maintain efficient and selective transport. It has been proposed that attractive interactions

Biological solutions to transport network design [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2007 Transport networks are vital components of multicellular organisms, distributing nutrients and removing waste products. Animal and plant transport systems are branching trees whose architecture is linked to universal scaling laws in these organisms.
