Charge separation in a copper(I) donor-chromophore-acceptor assembly for both photoanode and photocathode sensitization

Author(s): Singh Z; Chiong JD; Ricardo-Noordberg JF; Kamal S; Majewski MB;

A copper(I) donor-chromophore-acceptor triad bearing 1,8-napthalenemonoimide as the electron acceptor and triphenylamine as the electron donor was synthesized. Photophysical and electrochemical characterization suggest stepwise photoinduced charge separation upon excitation of the copper(I)-based metal-to-ligand charge transfer (MLCT) transition. Analyses ...

Perceived Facilitators and Barriers in Implementing Hospice Care: A Qualitative Study Among Health Care Providers in Binzhou, China

Author(s): Yu H; de Medeiros K;

Although many large Chinese cities have begun to implement hospice services, hospice care is still a relatively new concept in many parts of the country, especially in smaller cities. The purpose of this study was to gain a better understanding of health care providers' (physicians and nurses) perceptions of the facilitators and barriers to hospice ca ...

The effects of a 12-week combined motor control exercise and isolated lumbar extension intervention on lumbar multifidus muscle stiffness in individuals with chronic low back pain

Author(s): Tornblom A; Naghdi N; Rye M; Montpetit C; Fortin M;

Introduction: Exercise therapy is the primary endorsed form of conservative treatment for chronic low back pain (LBP). However, there is still conflicting evidence on which exercise intervention is best. While motor control exercise can lead to morphological and functional improvements of lumbar multifidus muscle in individuals with chronic LBP, the effec ...

Crowd Counting Using Meta-Test-Time Adaptation

Author(s): Ma C; Neri F; Gu L; Wang Z; Wang J; Qing A; Wang Y;

Machine learning algorithms are commonly used for quickly and efficiently counting people from a crowd. Test-time adaptation methods for crowd counting adjust model parameters and employ additional data augmentation to better adapt the model to the specific conditions encountered during testing. The majority of current studies concentrate on unsupervised ...

Developing endophytic Penicillium oxalicum as a source of lignocellulolytic enzymes for enhanced hydrolysis of biorefinery relevant pretreated rice straw

Author(s): Sharma G; Kaur B; Raheja Y; Kaur A; Singh V; Basotra N; Di Falco M; Tsang A; Chadha BS;

Endophytic fungi, as plant symbionts, produce an elaborate array of enzymes for efficient disintegration of lignocellulosic biomass into constituent monomeric sugars, making them novel source of lignocellulolytic CAZymes with immense potential in future biorefineries. The present study reports lignocellulolytic enzymes production potential of an endophyti ...

Measurement invariance and differential item functioning of the functionality appreciation scale (FAS) in Colombia and Spain

Author(s): Mebarak M; Maïano C; Mendoza J; Zamora Á; Baños R; Desdentado L; Miragall M; Herrero R; Swami V;

The Functionality Appreciation Scale (FAS) is increasingly used in diverse national and linguistic contexts. However, limited work has assessed the extent to which the instrument demonstrates measurement invariance and differential item functioning (DIF) across nations and respondent characterist ...

Analytical Model for Current-Voltage Characteristics in Perovskite Solar Cells Incorporating Bulk and Surface Recombination

Author(s): M Z Kabir

The effects of surface recombination on the steady-state carrier profiles and photocurrent in perovskite solar cells are investigated in this paper. The continuity equations for both holes and electrons are solved considering carrier drift and diffusion under the exponential carrier generation profile in the perovskite layer and considering both bulk and ...

Microfluidic Wound-Healing Assay for Comparative Study on Fluid Dynamic, Chemical and Mechanical Wounding on Microglia BV2 Migration

Author(s): Yazdanpanah Moghadam E; Sonenberg N; Packirisamy M;

Microglial cells, or brain immune cells, are highly dynamic and continuously migrate in pathophysiological conditions. Their adhesion, as a physical characteristic, plays a key role in migration. In this study, we presented a microfluidic chip combination of two assays: a microglial BV2 adhesion assay and a wound-healing migration assay. The chip could cr ...

Dual-Band Antenna Array Fed by Ridge Gap Waveguide with Dual-Periodic Interdigital-Pin Bed of Nails

Author(s): Chen B; Chen X; Cheng X; Da Y; Liu X; Gao S; Kishk AA;

A dual-band (K-/Ka-band) antenna array is presented. An ultra-wideband antenna element in the shape of a double-ridged waveguide is used as a radiation slot, and a novel dual-periodic ridge gap waveguide (RGW) with an interdigital-pin bed of nails (serving as a filter) is used to realize dual-band operation. By periodically arranging the pins of two diffe ...

MoEDAL Search in the CMS Beam Pipe for Magnetic Monopoles Produced via the Schwinger Effect

Author(s): Acharya B; Alexandre J; Behera SC; Benes P; Bergmann B; Bertolucci S; Bevan A; Brancaccio R; Branzas H; Burian P; Campbell M; Cecchini S; Cho YM; de Montigny M; De Roeck A; Ellis JR; Fairbairn M; Felea D; Frank M; Gould O; Hays J; Hirt A ...

We report on a search for magnetic monopoles (MMs) produced in ultraperipheral Pb-Pb collisions during Run 1 of the LHC. The beam pipe surrounding the interaction region of the CMS experiment was exposed to 184.07 µb^{-1} of Pb-Pb collisions at 2.76 TeV center-of-mass energy per collision in Dece ...

Development and psychometric evaluation of the Violation Appraisal Measure (VAM)

Author(s): Krause S; Radomsky AS;

Mental contamination refers to feelings of dirtiness and/or urges to wash that arise without direct contact with a contaminant. Cognitive models propose that this results from "serious, negative misappraisals of perceived violations". However, the specific violation misappraisals most relevant to mental contamination have yet to be established empirically ...

Older Adults in Administrative Quagmire: A Scoping Review of Policy and Program Coordination Across 6 Marginalized Older Adult Populations

Author(s): Marier P; Joy M; Smele S; Zakaria R; Beauchamp J; Bourgeois-Guérin V; Lupien PL; Sussman T;

Background and objectives: Coordination of governmental action is crowded with policies and programs that are highly interdependent, sometimes operating in silos if not contradicting each other. These dilemmas, or administrative quagmires, are heightened for older adults in general, but they are ...
