Surface-energy ratchet motor with geometrical symmetry driven by biased random walk
Scientific ReportsA geometrically symmetric gear with asymmetric surface wettability exhibits one-way spin on a vibrating water bed. On the side face of the gear, a parafilm was coated to create asymmetry in the surface energy.

Physics Letters B, 1991 Abstract Several infinite sets of models of random surfaces, defined by means of integrals over matrix ensembles, are solved in a double-scaling limit. These models are exactly soluble in at least two distinct large N limits. The triangulated surfaces are complicated due to the existence of two distinct kinds of vertices in the triangulations. In one

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Statistical and Fractal Analysis of Random Height Function
Communications, 2017 Nanostructured semiconductor surfaces are commonly used for suppression of the light reflection. We prepared several kinds of surface structures on silicon substrate and analyzed the properties of the random height function used for the description of ...

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Effect on oxides on surface topography and thermal contact resistance [PDF]
, 1979 The effect of oxides on the topographies of various random engineering surfaces and steady-state thermal contact resistances between oxidefree and oxidized metallic surfaces in contact in high vacua have been investigated. The results of many previous

FEBS Open Bio, EarlyView.Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Random walk in random environment with asymptotically zero perturbation [PDF]
, 2006 We give criteria for ergodicity, transience and null recurrence for the random walk in random environment on \Z+={0,1,2,…}, with reflection at the origin, where the random environment is subject to a vanishing perturbation.
