Scale-free random branching tree in supercritical phase

, 2007
We study the size and the lifetime distributions of scale-free random branching tree in which $k$ branches are generated from a node at each time step with probability $q_k\sim k^{-\gamma}$. In particular, we focus on finite-size trees in a supercritical

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)

Modeling the distribution of aftershocks data in Pakistan

Kashmir Journal of Science, 2022
In the present study an effort has been made to find out the best fitting distribution to explain the aftershocks behavior in Pakistan. For this purpose two parameter Gamma, Weibull, Lognormal, Frechet and three parameter Generalized Extreme Value and ...

Single spin asymmetries in $\gamma^* \gamma \to \pi \pi \pi$ at large Q^2

, 2000
The $\gamma^* \gamma \to \pi \pi \pi$ reaction is analysed in QCD at large photon virtuality Q and small hadronic mass W. Its amplitude factorizes in a $3 \pi$ generalized distribution amplitude and a hard subprocess $\gamma^* \gamma \to q \bar q$ or ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Point field models for the galaxy point pattern. Modelling the singularity of the two-point correlation function [PDF]

, 2002
There is empirical evidence that the two-point correlation function of the galaxy distribution follows, for small scales, reasonably well a power-law expression $\xi(r)\propto r^{-\gamma}$ with $\gamma$ between 1.5 and 1.9.

Potential therapeutic targeting of BKCa channels in glioblastoma treatment

Molecular Oncology, EarlyView.
This review summarizes current insights into the role of BKCa and mitoBKCa channels in glioblastoma biology, their potential classification as oncochannels, and the emerging pharmacological strategies targeting these channels, emphasizing the translational challenges in developing BKCa‐directed therapies for glioblastoma treatment.

Measurement Invariance, Entropy, and Probability

Entropy, 2010
We show that the natural scaling of measurement for a particular problem defines the most likely probability distribution of observations taken from that measurement scale.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Quantitative comparison of presumed-number-density and quadrature moment methods for the parameterisation of drop sedimentation

Meteorologische Zeitschrift, 2014
In numerical weather prediction models, parameterisations are used as an alternative to spectral modelling. One type of parameterisations are the so-called methods of moments.
