Joint received signal strength, angle-of-arrival, and time-of-flight positioning [PDF]

open access: yes, 2019
This paper presents a software positioning framework that is able to jointly use measured values of three parameters: the received signal strength, the angle-of-arrival, and the time-of-flight of the wireless signals.

Estuarine Nitrifiers: New Players, Patterns and Processes [PDF]

open access: yes, 2010
Ever since the first descriptions of ammonia-oxidizing Bacteria by Winogradsky in the late 1800s, the metabolic capability of aerobic ammonia oxidation has been restricted to a phylogenetically narrow group of bacteria.

Crystal structure of Plasmodium vivax macrophage migration inhibitory factor

open access: yesActa Crystallographica Section F, EarlyView.
The production, crystallization and 1.8 Å resolution crystal structure of macrophage migratory inhibitory factor from P. vivax are reported.Plasmodium vivax is a major cause of malaria globally and has recently been transmitted locally in the USA. P. vivax produces homologs of host proteins, including cytokines such as macrophage migration inhibitory ...

Drivers of archaeal ammonia-oxidizing communities in soil

open access: yesFrontiers in Microbiology, 2012
Soil ammonia-oxidizing archaea (AOA) are highly abundant and play an important role in the nitrogen cycle. In addition, AOA have a significant impact on soil quality.

THE TERRITORIALIZATION OF ANGOLA'S REAL ESTATE FRONTIER: How Private‐led Housing Developments are Reshaping the Outskirts of Luanda

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract Africa is recognized as the final frontier for urbanization and capitalism. Following a long wave of massive loans to promote state‐led developments, small private foreign and local developers are transforming the urban landscape on the outskirts of Luanda, forging partnerships with Angola's national and local governments and developing an ...

Artificial oocyte activation may improve embryo quality in older patients with diminished ovarian reserve undergoing IVF-ICSI cycles

open access: yesJournal of Ovarian Research, 2022
Background Artificial oocyte activation (AOA) is used to improve fertilization rate following fertilization failure after intracytoplasmic sperm injection (ICSI). Several studies have also shown that AOA may be involved in embryo development.

Parental Educational Attainment at Birth and Biomarkers of Male Fecundity: A Study From the Danish National Birth Cohort

open access: yesAndrology, EarlyView.
ABSTRACT Background Low parental education is associated with poorer offspring health, but its influence on male fecundity remains unclear. Objective To study the association between parental educational attainment at birth and biomarkers of male fecundity in young men and to explore whether this association is mediated by maternal smoking in pregnancy

Effect of Angle of Attack on Pressure and Lift Coefficient of ONERA OA206 Wing Model Using Computational Fluid Dynamics Method

open access: yesComputational and Experimental Research in Materials and Renewable Energy, 2019
In this study, we computed the lift force of the aircraft with ONERA OA206 airfoil type. It was positioned at 0%, 25%, 50%, 75%, and 100% of the wingspan for Angle of Attack (AoA) variations of 0o, 4o, 8o, 12o, and 16o.

Holding a Mirror to Ourselves: Remediation Policy in Surgical Training in Australia and Aotearoa New Zealand

open access: yesANZ Journal of Surgery, EarlyView.
ABSTRACT Introduction Remediation is a critical component of surgical training, designed to support trainees who are not progressing as expected and to ensure they reach the standards required. Despite its importance, remediation practices remain poorly understood. A clearer understanding of current remediation practices is essential if training bodies

Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization

open access: yesIEEE Open Journal of Signal Processing
Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.
