Analysis of a multi-component system with failure dependency, N-policy and vacations

Operations Research Perspectives, 2018
This paper studies a repairable k-out-of-n:G system with failure dependencies, N-policy and repairman’s multiple vacations. Whenever there are no broken components, the repairman leaves for a vacation which obeys a phase type distribution. Upon returning

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

New Bounds for All Types of Multi-state Consecutive $k$ -Out-of- $r$ -From- $n$ : F System Reliability

IEEE Access, 2019
A multi-state consecutive k-out-of-r-from-n: F system (named MS C(k,r,n:F)) comprises of n linearly ordered components. The MS C(k,r,n:F) and its components have more than 2 states: 0, 1,⋯,H.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The Reliability of Weighted k-out-of-n Systems with Randomized Components of Several Batches

پژوهش‌های ریاضی, 2021
One of the most important types of redundancy structures is weighted k-out-of-n system (which briefly denoted as weighted k/n system)‎. ‎In this paper‎, ‎a weighted k/n system‎ ‎with dependent components is considered and it is assumed that the ...

Availability Analysis and Optimal Design of Multistate Weighted ${k}$ -Out-of- ${n}$ Systems With Component Performance Requirements

IEEE Access, 2018
As one of the most typical multistate systems, weighted k-out-of-n system has been extensively studied in recent years. This paper presents a new kind of multistate weighted k-out-of-n system, which simultaneously considers performance requirements of ...

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 newfound relationship between extrachromosomal DNAs and excised signal circles

FEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Search for the K−pp bound state via the in-flight 3He(K−, n) reaction

EPJ Web of Conferences, 2014
In the J-PARC E15 experiment, a K− pp search was performed via the 3He(K−, n) reaction at 1.0 GeV/c. A forward-going neutron is detected by a neutron counter with 15 m flight length, and decay particles from K− pp are simultaneously measured by a ...
