Sequence Heterogeneity Accelerates Protein Search for Targets on DNA [PDF]
, 2015 The process of protein search for specific binding sites on DNA is fundamentally important since it marks the beginning of all major biological processes. We present a theoretical investigation that probes the role of DNA sequence symmetry, heterogeneity

Lepton Asymmetry of the Universe and Charged Quark-Gluon Plasma [PDF]
, 2000 The lepton asymmetry of order one is not excluded experimentally and, if present, can lead to interesting phenomena in the early Universe. It is shown that, when the temperature is above the quark-hadron transition, the lepton asymmetry induces chemical ...

Optimization of Biodiesel Production Using Immobilized Candida Rugosa Lipase on Magnetic Fe3O4-Silica Aerogel [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2019 Hydrophobic magnetic silica aerogel was used as a support to immobilize Candida rugosa lipase by adsorption method. Physical and chemical properties of the support and immobilized lipase were determined by Field Emission Scanning Electron Microscope ...

Rehydrogenation of Sodium Borates to Close the NaBH4-H2 Cycle: A Review
Energies, 2021 In 2007, the US Department of Energy recommended a no-go on NaBH4 hydrolysis for onboard applications; however, the concept of a NaBH4-H2-PEMFC system has the potential to become a primary source for on-demand power supply.

Extraction of Bioactive Compounds from C. vulgaris Biomass Using Deep Eutectic Solvents
Molecules, 2023 C. vulgaris microalgae biomass was employed for the extraction of valuable bioactive compounds with deep eutectic-based solvents (DESs). Particularly, the Choline Chloride (ChCl) based DESs, ChCl:1,2 butanediol (1:4), ChCl:ethylene glycol (1:2), and ChCl:

Intrinsic noise induced resonance in presence of sub-threshold signal in Brusselator
, 2011 In a system of non-linear chemical reactions called the Brusselator, we show that {\it intrinsic noise} can be regulated to drive it to exhibit resonance in the presence of a sub-threshold signal.

A two-compartment mechanochemical model of the roles of\ud transforming growth factor β and tissue tension in dermal wound healing [PDF]
, 2011 The repair of dermal tissue is a complex process of interconnected phenomena, where cellular, chemical and mechanical aspects all play a role, both in an autocrine and in a paracrine fashion.

Modelling chemotaxis of microswimmers: from individual to collective behavior
, 2019 We discuss recent progress in the theoretical description of chemotaxis by coupling the diffusion equation of a chemical species to equations describing the motion of sensing microorganisms. In particular, we discuss models for autochemotaxis of a single
