Bayesian Estimation of Traffic Intensity in M/D/1 Queue Relative to Balanced Loss Function

, 2022
In the Imbedded Markov Chain analysis of M/G/1 queue, X1, X2, ...Xn, ... is a sequence of i.i.d random variables. In particular, for the M/D/1 queue, the distribution of common random variable turns out to be well known Poisson distribution with mean ρ ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Two-Sample Prediction of Odd Generalized Exponential Inverted Weibull Distribution with theApplication on COVID-19 Mortality Rate [PDF]

المجلة العلمية للاقتصاد والتجارة
One of the most crucial issues in life testing is statistical prediction, which has also been used in business, engineering, medicine, and other fields. When more information are available, a better choice will be promoted.

Vergence and Standing Balance in Subjects with Idiopathic Bilateral Loss of Vestibular Function

PLoS ONE, 2013
There is a natural symbiosis between vergence and vestibular responses. Deficits in vergence can lead to vertigo, disequilibrium, and postural instability. This study examines both vergence eye movements in patients with idiopathic bilateral vestibular loss, and their standing balance in relation to vergence.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Loss of FTO Antagonises Wnt Signaling and Leads to Developmental Defects Associated with Ciliopathies [PDF]

, 2014
Common intronic variants in the Human fat mass and obesity-associated gene (FTO) are found to be associated with an increased risk of obesity. Overexpression of FTO correlates with increased food intake and obesity, whilst loss-of-function results in ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

The Exact Risks of Some Pre-Test and Stein-Type Regression Estimators Under Balanced Loss [PDF]

, 2017
In regression analysis we are often interested in using an estimator which is "precise" and which simultaneously provides a model with "good fit". In this paper we consider the risk properties of several estimators of the regression coefficient vector ...
