On the Linear Combination of Exponential and Gamma Random Variables

open access: yesEntropy, 2005
: The exact distribution of the linear combination α X + β Y is derived when X and Y are exponential and gamma random variables distributed independently of each other. A measure of entropy of the linear combination is investigated. We also provide

The spatial distribution of dark-matter-annihilation originated gamma-ray line signal

open access: yes, 2013
The GeV$-$TeV $\gamma-$ray line signal is the smoking gun signature of the dark matter annihilation or decay. The detection of such a signal is one of the main targets of some space-based telescopes, including Fermi-LAT and the upcoming CALET, DAMPE and ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS 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.

Modeling the distribution of aftershocks data in Pakistan

open access: yesKashmir 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 ...

Superdiffusion in Decoupled Continuous Time Random Walks

open access: yes, 2000
Continuous time random walk models with decoupled waiting time density are studied. When the spatial one jump probability density belongs to the Levy distribution type and the total time transition is exponential a generalized superdiffusive regime is ...

The density structure and star formation rate of non-isothermal polytropic turbulence [PDF]

open access: yes, 2015
The interstellar medium of galaxies is governed by supersonic turbulence, which likely controls the star formation rate (SFR) and the initial mass function (IMF).

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Effect of Statistical Fluctuation in Monte Carlo Based Photon Beam Dose Calculation on Gamma Index Evaluation

open access: yes, 2013
The gamma-index test has been commonly adopted to quantify the degree of agreement between a reference dose distribution and an evaluation dose distribution.

PICALM::MLLT10 translocated leukemia

open access: yesFEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...

Measurement Invariance, Entropy, and Probability

open access: yesEntropy, 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.
