Impacts of COVID-19 Pandemic on Ornamental Fish Supply Chain in Sri Lanka

open access: yesAsian Fisheries Science, 2021
Sri Lanka is one of the leading ornamental fish exporters globally, with total export earnings of around 15 million USD in 2019. The novel human coronavirus (COVID-19) pandemic has become a great threat to many industries worldwide, including the ...

Numerical approximation of poroelasticity with random coefficients using Polynomial Chaos and Hybrid High-Order methods [PDF]

open access: yes, 2019
In this work, we consider the Biot problem with uncertain poroelastic coefficients. The uncertainty is modelled using a finite set of parameters with prescribed probability distribution.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

An integrated control method for designing non-blocking supervisors using Petri nets

open access: yesAdvances in Mechanical Engineering, 2017
This article presents an efficient integrated approach on designing a non-blocking supervisor for the most general classes of Petri nets, called G -systems that allow multiple resource acquisitions.

Universal Construction for Polar Coded Modulation

open access: yesIEEE Access, 2018
Recently, the polarization weight (PW), independent of transmission channel, is proposed to construct the polar codes based on the partial orders (POs) of the polarized bit channels (PBCs).

DNA Barcoding of Fish Species Diversity in Guizhou, China

open access: yesDiversity, 2023
Guizhou is an important ecological barrier in the upper reaches of the Yangtze River and the Pearl River basins with abundant fish species. However, fish from these regions are threatened by anthropogenic activities, including overfishing and habitat ...

Towards an Efficient Finite Element Method for the Integral Fractional Laplacian on Polygonal Domains

open access: yes, 2017
We explore the connection between fractional order partial differential equations in two or more spatial dimensions with boundary integral operators to develop techniques that enable one to efficiently tackle the integral fractional Laplacian.

Mechanistic basis for inhibition of the extended‐spectrum β‐lactamase GES‐1 by enmetazobactam and tazobactam

open access: yesFEBS Letters, EarlyView.
Antimicrobial resistance (AMR) is of huge importance, resulting in over 1 million deaths each year. Here, we describe how a new drug, enmetazobactam, designed to help fight resistant bacterial diseases, inhibits a key enzyme (GES‐1) responsible for AMR. Our data show it is a more potent inhibitor than the related tazobactam, with high‐level computation

Cranial Morphology of the Carboniferous-Permian Tetrapod Brachydectes newberryi (Lepospondyli, Lysorophia): New Data from µCT. [PDF]

open access: yesPLoS ONE, 2016
Lysorophians are a group of early tetrapods with extremely elongate trunks, reduced limbs, and highly reduced skulls. Since the first discovery of this group, general similarities in outward appearance between lysorophians and some modern lissamphibian ...

Protein kinase FAM20C—when subcellular localization matters

open access: yesFEBS Letters, EarlyView.
FAM20C is a Golgi‐resident kinase that phosphorylates proteins along the entire secretory pathway. The presence of potential FAM20C substrates in the cytoplasm or nucleus raises the question of how the kinase and its substrates encounter each other. Protein kinases achieve signaling specificity through consensus sequence recognition and subcellular ...
