Drivers of archaeal ammonia-oxidizing communities in soil

Frontiers 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.

Secret Key Generation Based on AoA Estimation for Low SNR Conditions

, 2014
In the context of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. Therefore an accurate estimation of this characteristic is the core for reliable secret key generation ...

First Zoeal Stage of the Snapping Shrimp Alpheus Fabricius, 1798 (Caridea: Alpheidae): New Description of Alpheus bouvieri A. Milne‐Edwards, 1878 and Literature Review

Acta Zoologica, EarlyView.
ABSTRACT Based on adult morphological characters, the more than 300 species of Alpheus were divided into seven informal species groups, but some groups are not supported by molecular data. The aim here was to describe the zoea I of Alpheus bouvieri, and to do a review of the larval descriptions available in the literature, analysing whether the ...

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

Computational 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.

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

Journal 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.

Hydrazine Synthase From Anammox Is Inhibited by Linear and Aromatic Alkynes. [PDF]

Environ Microbiol
Linear and aromatic alkynes inhibit anammox in culture and in wetlands. The inhibition by alkynes is specific to the hydrazine synthase, a key enzyme in the anammox pathway. ABSTRACT N2O emissions by nitrifiers are often estimated using selective inhibitors, such as 1‐alkynes.

Lexical inference training for homonyms: Two randomized controlled trials for children with English as a first and an additional language

British Journal of Educational Psychology, EarlyView.
Abstract Background Many words have multiple meanings, which present challenges to learning, yet research has yet to identify effective interventions for homonyms. Lexical inference may be a promising strategy. Aim To evaluate a brief, novel lexical inference intervention for homonyms. Samples Children aged 7–8 years (Study 1: N = 180, Study 2: N = 76).

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

IEEE 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.

Device-to-Device Communications in the Millimeter Wave Band: A Novel Distributed Mechanism

, 2018
In spite of its potential advantages, the large-scale implementation of the device-to-device (D2D) communications has yet to be realized, mainly due to severe interference and lack of enough bandwidth in the microwave ($\mu$W) band.
