Analysis of Multi-Server Queueing System with Flexible Priorities

open access: yesMathematics, 2023
In this paper, a multi-server queueing system providing service to two correlated flows of requests was considered. Non-preemptive priority was granted to one flow via the preliminary delay of requests in the intermediate buffers with different rates of ...

Stability studies of isothiocyanates and nitriles in aqueous media [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2015
This is the first report to assess the stability of authentic commercial isothiocyanates and nitriles incubated anaerobically at 37 °C over 24 hrs in various aqueous solutions including nutrient broths with/without the presence of bacterial cells, and ...

Land Manager Perspectives on Conflict Mitigation Strategies for Urban Flying-Fox Camps

open access: yesDiversity, 2018
Over the last 20 years, there has been a notable increase in the presence of flying-foxes (Pteropodidae) in urban areas in Australia. Flying-foxes congregate during the day in camps which at times may contain many thousands of individuals. The associated

Organic buffers act as reductants of abiotic and biogenic manganese oxides

open access: yesScientific Reports, 2023
Proton activity is the master variable in many biogeochemical reactions. To control pH, laboratory studies involving redox-sensitive minerals like manganese (Mn) oxides frequently use organic buffers (typically Good’s buffers); however, two Good’s ...

Flow Cytometry for Estimating Plant Genome Size: Revisiting Assumptions, Sources of Variation, Reference Standards, and Best Practices

open access: yesJournal of the American Society for Horticultural Science
Flow cytometry has been widely used to estimate relative and absolute genome sizes (DNA contents) of plants for more than 50 years. However, the accuracy of these estimates can vary widely because of many factors, including errors in the genome size ...

A Project-Scheduling and Resource Management Heuristic Algorithm in the Construction of Combined Cycle Power Plant Projects

open access: yesComputers, 2022
Given the growing number of development projects, proper project planning and management are crucial. The purpose of this paper is to introduce a heuristic algorithm for scheduling a power plant project construction and project resource management to ...

The anti‐CRISPR protein AcrIE8.1 inhibits the type I‐E CRISPR‐Cas system by directly binding to the Cascade subunit Cas11

open access: yesFEBS Letters, EarlyView.
In this study, we present the structure of AcrIE8.1, a previously uncharacterized anti‐CRISPR protein that inhibits the type I‐E CRISPR‐Cas system. Through a combination of structural and biochemical analyses, we demonstrate that AcrIE8.1 directly binds to the Cas11 subunit of the Cascade complex to inhibit the CRISPR‐Cas system.

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...

Responses of Emergent Marsh Wetlands in Upstate New York to Variations in Urban Typology

open access: yesEcology and Society, 2004
Although it has been repeatedly demonstrated that urbanization has negative environmental consequences, the conversion of land to urban use is increasing worldwide and is not likely to abate. We tested the hypothesis that different urban typologies, i.e.,

Detrimental effect of zwitterionic buffers on lysosomal homeostasis in cell lines and iPSC-derived neurons [version 1; peer review: 3 approved]

open access: yesAMRC Open Research, 2020
Good’s buffers are commonly used for cell culture and, although developed to have minimal to no biological impact, they cause alterations in cellular processes such as autophagy and lysosomal enzyme activity. Using Chinese hamster ovary cells and induced
