Intelligent transportation related complex systems and sensors
(MPDI, 2021)Building around innovative services related to different modes of transport and traffic management, intelligent transport systems (ITSs) are being widely adopted worldwide to improve the efficiency and safety of the ... -
Chemical characterisation of benzene oxidation products under high- And low-NOx conditions using chemical ionisation mass spectrometry
(Copernicus GmbH, 2021)Aromatic hydrocarbons are a class of volatile organic compounds associated with anthropogenic activity and make up a significant fraction of urban volatile organic compound (VOC) emissions that contribute to the formation ... -
The origin and evolution of Lyα blobs in cosmological galaxy formation simulations
(IOP Publishing Ltd, 2021)High-redshift Lyα blobs (LABs) are an enigmatic class of objects that have been the subject of numerous observational and theoretical investigations. It is of particular interest to determine the dominant power sources for ... -
Draft genome sequence of the putative endophytic bacterium pantoea agglomerans r6, associated with lactuca serriola from South Africa
(American Society for Microbiology, 2021)Here, we present the draft genome sequence (;4.7 Mb) of the endopyhtic bacterium Pantoea agglomerans strain R6, which was isolated from surface-sterilized roots of Lactuca serriola (prickly lettuce) -
Enhanced low-humidity performance of proton exchange membrane fuel cell by incorporating phosphoric acid-loaded covalent organic framework in anode catalyst layer
(Elsevier, 2021)Developing self-humidifying membrane electrode assembly (MEA) is of great significance for the practical use of proton exchange membrane fuel cell (PEMFC). In this work, a phosphoric acid (PA)-loaded Schiff base networks ... -
Ion beam induced modification and nanostructures formation in thin SiC/Pd films on c-Si substrate
(Elsevier, 2021)Ion beam induced modification of thin metallic films is an emerging approach to grow metallic nanoparticles controllably. Modification of thin solid films is helpful in fabricating arrays of nanoscale particles for electronic ... -
Genome sequence of an alkaliphilus species isolated from historically contaminated sediments of the gulf of Naples (Mediterranean Sea)
(American Society for Microbiology, 2021)Here, we report the draft genome sequence of a metagenome-assembled genome (MAG) of a new Alkaliphilus bacterium, NP8, of the Clostridiaceae family. This bacterium was isolated from polluted sediment collected from an ... -
A two-step approach for detecting Striga in a complex agroecological system using Sentinel-2 data
(Elsevier, 2021)Information on weed occurrence within croplands is vital but is often unavailable to support weeding practices and improve cropland productivity assessments. To date, few studies have been conducted to estimate and map ... -
How much leaf area do insects eat? A data set of insect herbivory sampled globally with a standardized protocol
(Ecological Society of America, 2021)Herbivory is ubiquitous. Despite being a potential driver of plant distribution and performance, herbivory remains largely undocumented. Some early attempts have been made to review, globally, how much leaf area is removed ... -
The lofar two-meter sky survey: Deep fields data release 1: IV. Photometric redshifts and stellar masses
(EDP Sciences, 2021)The Low Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) is a sensitive, high-resolution 120-168 MHz survey split across multiple tiers over the northern sky. The first LoTSS Deep Fields data release consists of deep ... -
The LOFAR Two-metre sky survey deep fields: The star-formation rate-radio luminosity relation at low frequencies
(EDP Sciences, 2021)In this paper, we investigate the relationship between 150 MHz luminosity and the star-formation rate - the SFR-L150 MHz relation - using 150 MHz measurements for a near-infrared selected sample of 118 517 z < 1 galaxies. ... -
The lofar two-meter sky survey: Deep fields data release 1: II. The elais-n1 lofar deep field
(EDP Sciences, 2021)The LOFAR Two-metre Sky Survey (LoTSS) will cover the full northern sky and, additionally, aims to observe the LoTSS deep fields to a noise level of ? 10 μJy beam-1 over several tens of square degrees in areas that have ... -
The contribution of discrete sources to the sky temperature at 144 MHz
(EDP Sciences, 2021)In recent years, the level of the extragalactic radio background has become a point of considerable interest, with some lines of argument pointing to an entirely new cosmological synchrotron background. The contribution ... -
Updates and advances to the FAO56 crop water requirements method
(Elsevier, 2021)This study reviews the abundant research on FAO56 crop coefficients, published following introduction ofthe FAO56 paper in 1998. The primary goal was to evaluate, update, and consolidate the mid-season andend-season single ... -
Comparative analysis of the constitution and implementation of race/skin color field in health information systems: Brazil and South Africa
(Spinger, 2021)The inclusion of race/skin color in Health Information Systems makes it possible to measure health inequities. Brazil and South Africa correspond to countries marked by profound inequalities, multiracial constituted that ... -
Petrological, geochemical (major, trace, and rare earth elements), and U–Pb zircon data of the Tamatán Group, NE Mexico
(Elsevier, 2021)From samples of the Paleozoic Tamatán Group (Huizachal–Peregrina Anticlinorium, Tamaulipas, Mexico), petrographic (qualitative and modal) and geochemical analyses (major, trace, and rare earth elements) were conducted. The ... -
Physicochemical stability of enriched phenolic fractions of cyclopia genistoides and ex vivo bi-directional permeability of major xanthones and benzophenones
(Georg Thieme Verlag, 2021)Fractions of an ultrafiltered Cyclopia genistoides extract, respectively enriched in xanthones and benzophenones, were previously shown to inhibit mammalian α -glucosidase in vitro. The present study investigated ex vivo ... -
Proteomic identification and meta-analysis in salvia hispanica RNA-seq de novo assemblies
(2021)While proteomics has demonstrated its value for model organisms and for organisms with mature genome sequence annotations, proteomics has been of less value in nonmodel organisms that are unaccompanied by genome sequence ... -
