Low-cost anti-mycobacterial drug discovery using engineered E. coli

Nature Communications, 2022
Whole-cell screening for Mycobacterium tuberculosis inhibitors is complicated by the pathogen’s slow growth and biocontainment requirements. Here the authors develop engineered E.

An epistemology for democratic citizen science

Royal Society Open Science, 2023
More than ever, humanity relies on robust scientific knowledge of the world and our place within it. Unfortunately, our contemporary view of science is still suffused with outdated ideas about scientific knowledge production based on a naive kind of ...

Local existence and blowing up phenomena for a class of non-autonomous partial functional differential equations with infinite delay

Nonautonomous Dynamical Systems, 2022
In this work, we study a class of abstract non-autonomous partial functional differential equations with infinite delay. Our main results concern the local existence of the mild solution which can blow up at the finite time.

Variations in Marine Bacterial and Archaeal Communities during an Ulva prolifera Green Tide in Coastal Qingdao Areas

Microorganisms, 2022
Green tides caused by Ulva prolifera occur annually in the Yellow Sea, potentially influencing the marine microorganisms. Here, we focused on the variations in marine bacterial and archaeal communities during an U. prolifera green tide in coastal Qingdao

Genome and Ecology of a Novel Alteromonas Podovirus, ZP6, Representing a New Viral Genus, Mareflavirus

Microbiology Spectrum, 2021
Alteromonas is a ubiquitous, abundant, copiotrophic and phytoplankton-associated marine member of the Gammaproteobacteria with a range extending from tropical waters to polar regions and including hadal zones. Here, we describe a novel Alteromonas phage,

A choice of persistent identifier schemes for the Distributed System of Scientific Collections (DiSSCo) [PDF]

Research Ideas and Outcomes, 2021
Persistent identifiers (PID) to identify digital representations of physical specimens in natural science collections (i.e., digital specimens) unambiguously and uniquely on the Internet are one of the mechanisms for digitally transforming collections ...

A New Generalized Harmonic Evolution System [PDF]

, 2006
A new representation of the Einstein evolution equations is presented that is first order, linearly degenerate, and symmetric hyperbolic. This new system uses the generalized harmonic method to specify the coordinates, and exponentially suppresses all ...

Evolution equations in Fréchet spaces

Journal of Mathematical Sciences and Modelling, 2018
This paper deals with the existence of mild solutions for a class of evolution equations. The technique used is a generalization of the classical Darbo fixed point theorem for Fr\'{e}chet spaces associated with the concept of measure of noncompactness.
