Article Abstract

Zinc carbodiimide, Zn(CN), exhibits negative linear compressibility (NLC) along the -axis under hydrostatic pressure. Density functional theory calculations indicate that at high pressure, the - and -axes shrink, while the infinite -Zn-N-C-N- helical chains elongate through inter-chain Zn-N bonds, leading to expansion of the crystal along the -axis.

Global phosphorus (P) resources are facing a depletion crisis, and pyrolysis of P-rich sewage sludge (SS) offers significant resource potential. Optimizing pyrolysis conditions remains key yet challenging for enhancing P retention and bioavailability. This study conducted a correlation-prediction-causation integrated framework (CPCIF) to investigate how heating temperature (HT), heating rate (HR), and retention time (RT) influence total P enrichment rate (BTPE), relative inorganic P transformation rate (BITP), and relative apatite P transformation rate (BAIP) from SS to biochar during pyrolysis.

Background: Patient-reported missed nursing care is a critical indicator of care quality, while existing research focuses on nurses' workload and resource constraints as primary triggers, the role of emotional and interpersonal factors during nurse-patient encounters remains underexplored.

Objectives: To examine how nurses' emotions and perceptions of patients' families jointly influence patient-reported missed nursing care, using the Emotions as Social Information (EASI) model.

Design: A multi-source, nested, diary study design.

Objective: This study examined the effects of tetrahydrocannabinol (THC) and cannabidiol (CBD) on negative mood and drinking behaviors, and whether those effects were moderated by levels of perceived discrimination among participants who identify with a racial, ethnic, gender, or sexual identity that is underrepresented in research.

Methods: Participants were either not using cannabis, using cannabis with THC, or using cannabis with CBD and were assessed at baseline, 2 weeks, and 4-weeks following ad libitum use of a legal market cannabis product that was randomly assigned to them. Primary outcomes included scores on the Depression Anxiety Stress (DASS) Scale and number of drinking days.

Department of Ophthalmology and Vision Sciences, University of Toronto, Toronto, Ontario, Canada. Electronic address:

Topic: The aim of this systematic review and meta-analysis is to evaluate best-corrected visual acuity (VA) outcomes following transscleral cyclophotocoagulation (TSCPC) in patients with refractory glaucoma.

Clinical Relevance: TSCPC is typically reserved for cases of refractory glaucoma, due to apprehension of negative affects on VA. Prior studies have reported the VA outcomes from TSCPC, but no comprehensive review of the literature has yet been conducted.

Background: Parental vaccine hesitancy (VH) remains a public health concern in Georgia, where misinformation and distrust continue to hinder routine childhood immunization. VH is shaped by psychological, sociocultural, and informational factors, including trust in science, public authorities, and religious institutions. This study examined whether trust-related variables were stronger predictors of VH than traditional sociodemographic characteristics.
