Article Synopsis
- The paper introduces a novel metamaterial absorber design using a bent Y-shaped structure on an FR-4 substrate with copper, achieving over 90% absorption across a range of frequencies from L-band to K-band (3.728 GHz to 22.664 GHz).
- Through simulations, it identifies eight resonant frequencies, highlighting the design's versatility for reducing electromagnetic radiation.
- Additionally, the research discusses the implications of near-zero refractive index metamaterials and their potential for advanced wave control, emphasizing the absorber's polarization insensitivity and unique electromagnetic properties that challenge existing theories.
COVID-19 convalescent plasma (CCP) was one of the first therapies to receive emergency use authorization for management of COVID-19. We assessed the effectiveness of CCP in a propensity-matched analysis, and whether the presence of antibodies in the recipient at the time of treatment or the titer of antibodies in the administered CCP influenced clinical effectiveness. In an inpatient population within a single large health system, a total of 290 CCP patients were matched to 290 controls.

Methods: A steering committee (including eight individuals with lived experience/charity representatives and six clinicians) designed a survey which asked stakeholders to list three questions about type 1 diabetes. This was disseminated through social media, direct email contact, and printed posters.
GABABRs are key membrane proteins that continually adapt the excitability of the nervous system. These G-protein coupled receptors are activated by the brain's premier inhibitory neurotransmitter GABA. They are obligate heterodimers composed of GABA-binding GABABR1 and G-protein-coupling GABABR2 subunits.

Aim: To identify research priorities regarding the effectiveness of interventions for children and young people (CYP) with childhood neurological conditions (CNCs). These include common conditions such as epilepsies and cerebral palsy, as well as many rare conditions.
Method: The National Institute for Health and Care Research (NIHR) and the James Lind Alliance (JLA) champion and facilitate priority setting partnerships (PSPs) between patients, caregivers, and clinicians (stakeholders) to identify the most important unanswered questions for research (uncertainties).
