Transport Equations and Criteria for Active Transport [PDF]
American Zoologist, 1970 The relation between driving forces and the flux of solutes that would be expected in a passive system is derived. This relation is a differential equation and different solutions are obtained which apply to different experimental conditions. Solutions are given for the cases of pure convective flow, diffusion, electrophoretic mobility, balance between

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Blow-up criterion for the 2D Euler-Boussinesq system in terms of temperature
Electronic Journal of Differential Equations, 2016 In this article, we study the blow-up slutions for the 2D Euler-Boussinesq equation. In particular, it is shown that if $$ \int_0^{T^*} \sup_{r\geq 2}\frac{\|\Lambda^{1-\alpha} \theta(t)\|_{L^{r}}} {\sqrt{r\log r ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

The eigenvalues of one-speed neutrons in a slab with forward and backward scattering
Tehnički Glasnik, 2019 The eigenvalue spectrum is studied for one-speed neutrons in a slab with forward and backward scattering. First, the transport equation describing the interaction of neutrons in a system with general geometry is given.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Scaling the Dynamic Buckling Behavior of a Box Girder Based on the Finite Similitude Approach
Journal of Marine Science and EngineeringIn the design of small-scale test models for hull structures, the directional dimensional analysis method is commonly employed. However, conventional dimensional analysis based on elasticity theory may be insufficient to capture the nonlinear behaviors ...
