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.

L2 Chinese Grammatical Acquisition and Processing: A Substantive and Methodological Review

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT This study presents a systematic review of 92 empirical studies on Chinese as a second language (CSL) in grammatical processing and development, synthesizing their substantive foci and methodological characteristics. The results reveal consistent scholarly attention to cross‐linguistic topics, with less focus on features that are distinctively

The efficacy of ionomycin - induced artificial oocyte activation in preventing fertilization failure in an ICSI cycle: an eight - year retrospective study

open access: yesJournal of Ovarian Research
Background Artificial oocyte activation (AOA) procedure may prevent the occurrence of fertilization failure following ICSI; however, the specific efficacy of AOA remains controversial.

A spatiotemporal analysis of Salmonella bacteraemia in Queensland, 2010–2019

open access: yesInternal Medicine Journal, EarlyView.
Abstract Background Salmonellosis contributes to a significant burden on global healthcare systems. The impact of this foodborne bacterium is more pronounced when the infection is invasive, leading to bacteraemia and sepsis. Studies on invasive salmonellosis are few, and there is an urgent need to understand the spatial distribution of bacteraemia and ...

Two-Dimensional AOA Estimation Based on a Constant Modulus Algorithm [PDF]

open access: yes, 2017
We propose a two-dimensional (2D) angle of arrival (AOA) estimator using the algebraic constant modulus algorithm (ACMA). This algorithm was originally introduced to estimate the one-dimensional (1D) AOA.

Carryover of Aflatoxin From Dairy Feed to Milk: A Systematic Review (1 January 2004–31 December 2024)

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Aflatoxins, toxic metabolites produced by Aspergillus species, are frequently reported contaminants of dairy cattle feed worldwide, particularly in tropical and subtropical regions where climatic conditions favor fungal growth, and they can be transferred into milk and dairy products.

Language Dominance Shapes Protracted Development of Nonpersonal Clitics (Even) in Cases of Widespread Bilingualism

open access: yesLanguage Learning, EarlyView.
Abstract Little research has explored how language dominance may affect the development and ultimate attainment of morphosyntax in a situation of widespread and social bilingualism, where exposure to both languages starts early on and can be sustained over time.

Oxygen isotope thermometry and composition of aqueous fluids within the parent body of asteroid (101955) Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report on the petrography and oxygen isotopic compositions from in situ analyses of carbonates (Ca‐carbonate, dolomite, and Fe‐rich magnesite), magnetite, and apatite in particles from asteroid Bennu. Using oxygen isotope thermometry of Ca‐carbonate, dolomite, and magnetite, we estimated crystallization temperatures and the oxygen isotopic ...
