Multi-cell NOMA: Coherent Reconfigurable Intelligent Surfaces Model With Stochastic Geometry [PDF]

arXiv, 2021
Reconfigurable intelligent surfaces (RISs) become promising for enhancing non-orthogonal multiple access (NOMA) systems, i.e., enhancing the channel quality and altering the SIC orders. Invoked by stochastic geometry methods, we investigate the downlink coverage performance of RIS-aided multi-cell NOMA networks.

Does Mental Health First Aid training improve the mental health of aid recipients? The training for parents of teenagers randomised controlled trial

BMC Psychiatry, 2019
BackgroundThere is well-established evidence that Mental Health First Aid (MHFA) training improves knowledge about how to support someone developing a mental health problem, but less evidence that this support improves the mental health of the recipient ...

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

FEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Reconfigurable Intelligent Surface-Aided NOMA with Limited Feedback [PDF]

arXiv, 2023
The design of feedback channels in frequency division duplex (FDD) systems is a major challenge because of the limited available feedback bits. We consider non-orthogonal multiple access (NOMA) systems that incorporate reconfigurable intelligent surfaces (RISs).

Helping adolescents to better support their peers with a mental health problem: A cluster-randomised crossover trial of teen Mental Health First Aid

Australian and New Zealand journal of psychiatry (Print), 2018
Background: teen Mental Health First Aid (tMHFA) is a classroom-based training programme for students aged 15–18 years to improve supportive behaviours towards peers, increase mental health literacy and reduce stigma.

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

FEBS Letters, EarlyView.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

What level of support is required to enable secondary school teachers to effectively teach first aid? A randomized trial

London Review of Education, 2020
In light of the UK government’s decision to make first aid education mandatory in schools, this article adds to the body of evidence to inform the implementation of this decision.

Growth patterns and scaling laws governing AIDS epidemic in Brazilian cities [PDF]

, 2014
Brazil holds approximately 1/3 of population living infected with AIDS (acquired immunodeficiency syndrome) in Central and South Americas, and it was also the first developing country to implement a large-scale control and intervention program against AIDS epidemic.

Elucidation of interface interactions between a dehydratase domain and an acyl carrier protein in cremimycin polyketide synthase

FEBS Letters, EarlyView.
In modular polyketide synthases, the dehydratase (DH) domain catalyzes the dehydration reaction of the β‐hydroxyacyl unit attached to the cognate acyl carrier protein (ACP) domain. However, it is unclear how DH interacts with ACP during the reaction. In this study, we identified DH–ACP interface residues, providing the first detailed insights into DH ...
