Design and analysis of a 60 GHz high gain wideband magneto electric dipole antenna array based on trapped printed gap waveguide technology

Author(s): Hamada H; Ali MMM; Shams SI; Khalaf AAM; Allam AMMA;

This paper introduces an innovative design and analysis of a magneto-electric dipole antenna exhibiting high-gain, ultra-wideband operation, and stable radiation characteristics in the 60-GHz mm-wave band. Furthermore, the trapped printed gap waveguide (TPGW) technology is presented as a low-cost, minimal-loss, and low-dispersion guiding structure to feed ...

Characterizing spatiotemporal white matter hyperintensity pathophysiology in vivo to disentangle vascular and neurodegenerative contributions

Author(s): Parent O; Alasmar Z; Osborne S; Bussy A; Costantino M; Fouquet JP; Quesada D; Pastor-Bernier A; Fajardo-Valdez A; Pichet-Binette A; McQuarrie A; Maranzano J; Devenyi GA; Steele CJ; Villeneuve S; ; Dadar M; Chakravarty MM;

White matter hyperintensities (WMHs) are neuroimaging markers widely interpreted as caused by cerebral small vessel disease, yet emerging evidence suggests that a subset may have a neurodegenerative etiology. Current imaging methods have lacked the specificity to disentangle biological processes ...

Upconversion Lanthanide-Based 2D Metal-Organic Frameworks for Multimode Information Encryption

Author(s): Chen J; Xie Y; Yang W; Sun R; Xing F; Mandl GA; Capobianco JA; Sun L;

Luminescent 2D metal-organic frameworks (MOFs) are a class of metal-organic framework materials expanded in a 2D plane, which have a wide range of applications in fields of optoelectronic devices, sensors, and information storage due to their unique layered structure and excellent optical properties. Currently, research on luminescent 2D MOFs mainly focus ...

Potential value streams of an integrated Canadian serosurveillance network

Author(s): Campbell JR; Russell WA; Wagner CE; Manuel DG; Anipindi V; Baral P; Evans TG; Hankins CA; Sander B;

The Government of Canada, through the COVID-19 Immunity Task Force (CITF), supported over 100 serosurveillance studies during the COVID-19 pandemic, building and strengthening the technical infrastructure necessary for a national serosurveillance network. The value of such a network extends beyon ...

Contextual variations in the effects of social withdrawal, peer exclusion, and friendship on growth curves of depressed affect in late childhood

Author(s): Commisso M; Persram RP; Lopez LS; Bukowski WM;

The moderating roles of friendship and contextual variables on associations between social withdrawal and peer exclusion and growth curves of depressed affect were studied with a three-wave multilevel longitudinal design. Participants were 313 boys and girls aged 10-12 from Canada (n = 139), mostly of European and North African descent, and Colombia (n = ...

PARPAL: PARalog Protein Redistribution using Abundance and Localization in Yeast Database

Author(s): Greco BM; Zapata G; Dandage R; Papkov M; Pereira V; Lefebvre F; Bourque G; Parts L; Kuzmin E;

Whole-genome duplication (WGD) events are common across various organisms; however, the retention and evolution of WGD paralogs is not fully understood. Quantitative measure of protein redistribution in response to the deletion of their WGD paralog provides insight into sources of gene retention. ...

Single-cell imaging of protein dynamics of paralogs reveals sources of gene retention

Author(s): Dandage R; Papkov M; Greco BM; Pereira V; Fishman D; Friesen H; Wang K; Styles EB; Kraus O; Grys B; Zapata G; Lefebvre F; Bourque G; Boone C; Andrews BJ; Parts L; Kuzmin E;

Gene duplication is common across the Tree of Life and contributes to genomic robustness. In this study, we examined changes in the subcellular localization and abundance of proteins in response to the deletion of their paralogs originating from the whole-genome duplication event, which is a larg ...

No species left behind: borrowing strength to map data-deficient species

Author(s): Sharma S; Winner K; Pollock LJ; Thorson JT; Mäkinen J; Merow C; Pedersen EJ; Chefira KF; Portmann JM; Iannarilli F; Beery S; de Lutio R; Jetz W;

We lack the data needed to detect and understand biodiversity change for most species, despite some species having millions of observations. This unequal data coverage impedes conservation planning and our understanding of biodiversity patterns. The 'borrowing strength' approach leverages ...

Multiphase OH Oxidation of Bisphenols: Chemical Transformation and Persistence in the Environment

Author(s): Yu J; Wu B; Peng C; Wentzell J; Wheeler MJ; Osagu JO; Zhang X; Li L; Abbatt JPD; Liggio J;

Bisphenol A (BPA) is a common endocrine disruptor widely found in commercial products. Despite negative human health effects, its usage is not fully banned worldwide with ongoing human exposure from sources including dust, aerosol particles, and surfaces. Although attention has been paid to the a ...

Effect of chronic benzodiazepine and benzodiazepine receptor agonist use on sleep architecture and brain oscillations in older adults with chronic insomnia

Author(s): Barbaux L; Perrault AA; Cross NE; Weiner OM; Es-Sounni M; Pomares FB; Tarelli L; McCarthy M; Maltezos A; Smith D; Gong K; O' Byrne J; Yue V; Desrosiers C; Clerc D; Andriamampionona F; Lussier D; Gilbert S; Tannenbaum C; Gouin JP; Da ...

Study objectives: Insomnia in older adults is associated with widespread benzodiazepine (BZD) and benzodiazepine receptor agonist (BZRA) use, despite evidence that chronic use disrupts sleep regulation and cognition. Little is known about BZD/BZRA effects on NREM slow oscillations (SO), spindles ...

Threatened Birds in a Changing Mediterranean Wetland: Long-Term Trends and Climate-Driven Threats

Author(s): Bouregbi I; Bensakhri Z; Zebsa R; Zouaimia A; Bensouilah S; Bouteraa O; Khelifa R; Ouakid ML; Mahdjoub H; Houhamdi M;

Understanding the impact of climate change on waterbirds, particularly those of conservation concern, is essential for their long-term management and effective conservation. In arid regions such as North Africa, wetlands of international importance have been affected by severe drought events, but ...
