Enhanced terahertz radiation directivity via a conical horn antenna from on-chip spintronic emitters.

A circular waveguide-fed conical horn antenna is fabricated using two-photon lithography (TPL) and integrated with a spintronic terahertz radiation emitter source to provide enhanced radiation directivity. In comparison to the bare terahertz radiation source, incorporating the antenna permits a spectral density gain up to 20.5 dB.

Engineering a dual vaccine against COVID-19 and tuberculosis.

The COVID-19 pandemic, caused by SARS-CoV-2 virus, has been one of the top public health threats across the world over the past three years. BCG is currently the only licensed vaccine for tuberculosis, one of the deadliest infectious diseases in the world, that is caused by . In the past decades, recombinant BCG has been studied as a novel vaccine vector for other infectious diseases in humans besides tuberculosis, such as viral infections.

Advance care and resuscitation plans in a tertiary hospital: a multimodal approach.

Objectives: Advance care planning (ACP) is the process of documenting a person's preference for medical treatment in the event of future deterioration. This audit aimed to improve discussion and documentation of ACP in patients who die during a hospital admission.

Methods: We performed a clinical audit in 2021 of inpatients at a tertiary hospital in Sydney, Australia to evaluate the benefit of multimodal interventions to improve ACP compared with previous audits from 2016 and 2011.

Impairments to executive function in emerging adults with Huntington disease.

Background And Objectives: The clinical diagnosis of Huntington disease (HD) is typically made once motor symptoms and chorea are evident. Recent reports highlight the onset of cognitive and psychiatric symptoms before motor manifestations. These findings support further investigations of cognitive function across the lifespan of HD sufferers.

Inhibitory control, working memory and coping with stress: Associations with symptoms of anxiety and depression in adults with Huntington's disease.

Objective: Huntington's disease (HD) is an autosomal dominant neurodegenerative disease characterized by neuropsychiatric symptoms (e.g., anxiety and depression), where individuals suffer high levels of stress from the social, physical, and cognitive burden of the disease.
