Group acceptance sampling plan based on truncated life tests for the Kumaraswamy Bell–Rayleigh distribution

open access: yesScientific African
This article is focusing on a group acceptance sampling plan for the Kumaraswamy Bell–Rayleigh distribution based on truncated life tests. For a specified group, the mean ratio as a quality measure is being used to determine the minimum number of lots ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Positioning and orienting a static cylindrical radio-reflector for wide field surveys

open access: yes, 2012
Several projects in radioastronomy plan to use large static cylindrical reflectors with an extended lobe sampling a sector of the rotating sky. This study provides the exact mathematical expression of the transit time of a celestial object within the ...

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Acceptance Sampling Plans Based on Truncated Life Tests for Sushila Distribution

open access: yesJournal of Mathematical and Fundamental Sciences, 2018
An acceptance sampling plan problem based on truncated life tests when the lifetime following a Sushila distribution is considered in this paper. For various acceptance numbers, confidence levels and values of the ratio between fixed experiment time and ...

Rejection sampling in demand systems [PDF]

open access: yes, 1992
We illustrate the method of rejection sampling in a Bayesian application of a new approach toı estimating Demand Systems. This approach, suggested by Varian (1990), is based on a generalization of Afriat's (1967) efficiency index.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A more flexible Lomax distribution: Characterization, estimation, group acceptance sampling plan and applications

open access: yesAlexandria Engineering Journal
The objectives of this paper are threefold. First, we introduce a novel distribution, named the Odd Perks-Lomax (OPL) distribution, which is derived from the Odd Perks-G family of distributions.
