Semidefinite Programming Algorithms for 3-D AOA-Based Hybrid Localization

IEEE Open Journal of Signal Processing, 2023
By taking different kinds of measurements at the same time, it may be possible to improve the accuracy of target localization or reduce the number of sensors needed.

A Simple AoA Estimation Scheme

CoRR, 2014
We propose an intuitive, simple and hardware friendly, yet surprisingly novel and efficient, received signal's angle of arrival (AoA) estimation scheme. Our intuitive, two-phases cross-correlation based scheme relies on a switched beam antenna array, which is used to collect an omni-directional signal using few elements of the antenna array in the ...

Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Novel PLCZ1 mutation caused polyspermy during in vitro fertilization

Asian Journal of Andrology
Failure of oocyte activation, including polyspermy and defects in pronuclear (PN) formation, triggers early embryonic developmental arrest. Many studies have shown that phospholipase C zeta 1 (PLCZ1) mutations cause failure of PN formation following ...

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

APTNet: A Condition‐Sensitive Modulation Framework for Surface Pressure Prediction on Supersonic Aircraft

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Accurate surface‐pressure prediction over broad operating envelopes is critical for supersonic aerodynamic analysis and design. To overcome the bottlenecks of traditional computational fluid dynamics (CFD) in real‐time performance and computational efficiency, data‐driven deep learning methods have emerged. However, existing data‐driven models

Effects of α-aminooxyacetic acid on the level of polyamines, anthocyanins and photosynthetic pigments in seedlings of common buckwheat (Fagopyrum esculentum Moench)

Acta Societatis Botanicorum Poloniae, 2011
The present paper discusses the effects of α-aminooxyacetic acid (AOA) on contents of polyamines, anthocyanins, photosynthetic pigments and phenylalanine ammonia-lyase activity in seedlings of common buckwheat (Fagopyrum esculentum Moench).

Niche Differentiation of Bacterial Versus Archaeal Soil Nitrifiers Induced by Ammonium Inhibition Along a Management Gradient

Frontiers in Microbiology, 2020
Soil nitrification, mediated mainly by ammonia oxidizing archaea (AOA) and bacteria (AOB), converts ammonium (NH4+) to nitrite (NO2−) and thence nitrate (NO3−).

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

International 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 ...

PARTICIPATORY BUDGETING IN AUTOCRACIES: Conflicting Logics, Unintended Consequences and Contentious Participation in Angola's Orçamento Participativo

International Journal of Urban and Regional Research, EarlyView.
Abstract Participatory institutions are no longer confined to liberal democracies as autocrats around the world experiment with ‘authoritarian participation’. This also applies to the most successful democratic innovation of recent decades: participatory budgeting (PB).
