Active systems are characterized by a continuous production of entropy at steady state. We study the statistics within lattice-based model interacting active particles that is capable motility-induced phase separation. Exploiting recent formulation exact fluctuating hydrodynamics for this model, we provide analytical results its in both typical and atypical (biased) regimes. This complements pr...

Using a minimal model of active Brownian discs, we study the effect crucial parameter, namely softness inter-particle repulsion, on motility-induced phase separation. We show that an increase in particle reduces ability system to phase-separate and exhibit delayed transition. After separation, state properties can be explained by single relevant lengthscale, effective distance. estimate this le...

In recent years, individuals are rampantly exposed to vapours of benzene, through paint, plastic, petroleum industries, fuel exhaust, and tobacco smoke. Hence the present investigation was directed towards determining the effect of benzene metabolites, namely, phenol-hydroquinone and catechol, on the motility, viability, and nuclear integrity of the human spermatozoa. From the results obtained ...

Flagellar motility, a mode of active motion shared by many prokaryotic species, is recognized as a key mechanism enabling population dispersal and resource acquisition in microbial communities living in marine, freshwater, and other liquid-replete habitats. By contrast, its role in variably hydrated habitats, where water dynamics result in fragmented aquatic habitats connected by micrometric fi...

The fathead minnow (Pimephales promelas) is an OECD-proposed test species routinely used in reproductive toxicity trials with suspected endocrine-disrupting compounds (EDCs). The basic fecundity, endocrinology, and histopathology of reproductively active male and female fathead minnows has been well characterized, but there are few studies of the utility of male sperm concentration and motility...

The Hedgehog (Hh) signaling pathway initiates an evolutionarily conserved developmental program required for the proper patterning of many tissues [1]. Although Costal2 (Cos2) is a requisite component of the Hh pathway, its mechanistic role is not well understood. Because of its primary sequence, Cos2 was initially predicted to function as a kinesin-like protein [2]. However, evidence showing t...

Sperm motility is necessary for the transport of male DNA to eggs in species with both external and internal fertilization. Flagella comprise several proteins for generating and regulating motility. Central cytoskeletal structures called axonemes have been well conserved through evolution. In mammalian sperm flagella, two accessory structures (outer dense fiber and the fibrous sheath) surround ...

Toxoplasma gondii is an obligate intracellular parasite that enters cells by a process of active penetration. Host cell penetration and parasite motility are driven by a myosin motor complex consisting of four known proteins: TgMyoA, an unconventional Class XIV myosin; TgMLC1, a myosin light chain; and two membrane-associated proteins, TgGAP45 and TgGAP50. Little is known about how the activity...
