Observing and braiding topological Majorana modes on programmable quantum simulators.

Electrons are indivisible elementary particles, yet paradoxically a collection of them can act as a fraction of a single electron, exhibiting exotic and useful properties. One such collective excitation, known as a topological Majorana mode, is naturally stable against perturbations, such as unwanted local noise, and can thereby robustly store quantum information. As such, Majorana modes serve as the basic primitive of topological quantum computing, providing resilience to errors.

Knowledge, attitudes and practices concerning breast cancer, cervical cancer and screening among healthcare professionals and students in Mogadishu, Somalia: a cross-sectional study.

Introduction: Somali women face exceptionally high mortality and incidence rates from both breast cancer (BC) and cervical cancer (CC). They experience the highest age-standardised BC mortality rate in Africa and an age-standardised BC incidence rate of 41.7 per 100,000 women.

COVID-19 vaccine perceptions in the initial phases of US vaccine roll-out: an observational study on reddit.

Background: Open online forums like Reddit provide an opportunity to quantitatively examine COVID-19 vaccine perceptions early in the vaccine timeline. We examine COVID-19 misinformation on Reddit following vaccine scientific announcements, in the initial phases of the vaccine timeline.

Methods: We collected all posts on Reddit (reddit.

Knowledge of and preparedness for COVID-19 among Somali healthcare professionals: A cross-sectional study.

Background: Somalia is considered severely underprepared to contain an outbreak of COVID-19, with critical shortages in healthcare personnel and treatment resources. In limited-resource settings such as Somalia, providing healthcare workers with adequate information on COVID-19 is crucial to improve patient outcomes and mitigate the spread of the SARS-CoV-2 virus. This study assessed the knowledge of, preparedness for, and perceptions toward COVID-19 prevention and treatment among Somali healthcare workers.

Knowledge and perceptions of COVID-19, prevalence of pre-existing conditions and access to essential resources in Somali IDP camps: a cross-sectional study.

Objectives: This study examined knowledge and perceptions of COVID-19, prevalence of pre-existing conditions and access to essential resources among residents of internally displaced person (IDP) camps in Somalia, where overcrowded settlements with weakened infrastructure, inadequate water, sanitation, and hygiene facilities, and limited access to health services make this vulnerable population particularly susceptible to a COVID-19 outbreak.

Design: A descriptive, cross-sectional survey.

Setting: Twelve IDP camps across six areas of the Lower Shabelle region in Somalia.
