Dense direct-current (DC) bias routing and numerous radio-frequency (RF) choke inductors pose major challenges to the practical implementation of phase-shifter-free beam steering using PIN-controlled phase switching. To address this issue, a compact vertical DC biasing network is proposed, in which most DC bias lines are routed beneath the ground plane. T ...

Background: The COVID-19 pandemic demanded evidence synthesis approaches that could keep pace with rapidly evolving science and urgent policy needs. Rapid reviews and living evidence syntheses (LES) emerged as critical methodological responses, yet limited guidance exists for teams undertaking such work, particularly regarding the operational challenges o ...

Co-pollution of nitrate and tetracycline (TC) poses a critical barrier to efficient biological treatment due to impaired electron transfer, diminished microbial metabolic activity, and disrupted community structure. To address this challenge, this study synthesized an iron-nitrogen-doped carbon material (Fe-NC) featuring electron-withdrawing pyridinic nit ...

Urbanization drives rapid and extreme environmental change, profoundly shaping the ecology and evolution of populations. In this Perspective, we call for the integration and development of evolutionary theory and empirical research through collaboration between theoretical and experimental biolog ...

Arginase is a binuclear manganese metalloenzyme that modulates L-arginine availability and downstream metabolic pathways. It was hypothesized that C-terminal arginine-containing peptides generated through simulated gastrointestinal digestion of white lupin (Lupinus albus) proteins would exhibit arginase inhibitory activity. To test this hypothesis, integr ...

While landscape connectivity is an important focus of Canada's conservation goals, Canadian national parks are vulnerable to habitat loss, the breaking-up of habitat patches, and a reduction in their connectivity to surrounding ecosystems. This study measured landscape fragmentation in 43 Canadian national parks and control areas throughout their hist ...

Background: Aortic regurgitation (AR) alters normal blood flow patterns in the left ventricle (LV), affecting diastolic filling dynamics, and is commonly quantified by the regurgitant fraction (RF). However, conventional diagnostic methods have notable limitations, prompting growing interest in four-dimensional flow magnetic resonance imaging (4D-flow MRI ...

Cytokinesis, the final step of cell division, relies on ingression of a precisely positioned actomyosin ring. Chromatin-associated Ran-GTP fine-tunes ring position, although the mechanism remains unclear. We hypothesize that depletion of Ran-GTP between segregating chromosomes leads to equatorial enrichment of importins, promoting recruitment of the scaff ...

Speaking more than one language is hypothesized to lead to greater brain resilience in aging and Alzheimer's disease, resulting in a delay in the symptom onset of Alzheimer's disease. While previous research has used structural neuroimaging measures to explore the neural underpinnings of this protective effect, few studies have used functional bra ...

Homelessness remains an enduring social issue, in part, due to the stigmatization of and discrimination toward people experiencing homelessness, known as homeism. Despite extant research on the topic, little is known about how homeism, enacted through stigmatization and discrimination, may occur within transitional housing programs or among older people e ...

Three new isatin-pyridine-2-oxime hybrids (AM01-03) were synthesized and experimentally evaluated as reactivators of acetylcholinesterase (AChE) inhibited by a surrogate of the nerve agent A-242, in comparison with their 4-oxime isomers previously reported by our research group. Furthermore, the ...
