Cryogenic in-memory computing using magnetic topological insulators.

Machine learning algorithms have proven to be effective for essential quantum computation tasks such as quantum error correction and quantum control. Efficient hardware implementation of these algorithms at cryogenic temperatures is essential. Here we utilize magnetic topological insulators as memristors (termed magnetic topological memristors) and introduce a cryogenic in-memory computing scheme based on the coexistence of a chiral edge state and a topological surface state.

Household Air Pollution Exposures Over Pregnancy and Maternal Blood Pressure Trajectories through 8 Years Postpartum: Evidence from the Ghana Randomized Air Pollution and Health Study (GRAPHS).

Background: Household air pollution is a major contributor to cardiovascular disease burden in women in Sub-Saharan Africa. However, little is known about exposures during pregnancy or the effect of clean cooking interventions on postpartum blood pressure trajectories.

Methods: The Ghana Randomized Air Pollution and Health Study (GRAPHS) randomized 1414 non-smoking women in the first and second trimesters to liquefied petroleum gas (LPG) or improved biomass stoves - vs control (traditional three-stone open fire).

Urinary tract infections among pregnant women in rural West Amhara, Ethiopia: Prevalence, bacterial etiology, risk factors, and antimicrobial resistance patterns.

Urinary Tract Infections (UTIs) in pregnant women can lead to pyelonephritis and preterm birth. We assessed UTI prevalence, etiology, antimicrobial resistance, and associated risk factors among pregnant women receiving antenatal care in rural Amhara, Ethiopia. 604 pregnant women were screened for UTI at ≤ 24 weeks gestational age from August 2020 to June 2022.

Fabrication of a micropatterned shape-memory polymer patch with L-DOPA for tendon regeneration.

A scaffold design for tendon regeneration has been proposed, which mimics the microstructural features of tendons and provides appropriate mechanical properties. We synthesized a temperature-triggered shape-memory polymer (SMP) using the ring-opening polymerization of polycaprolactone (PCL) with polyethylene glycol (PEG) as a macroinitiator. We fabricated a micropatterned patch using SMP capillary force lithography, which mimicked a native tendon, for providing physical cues and guiding effects.

The hypercapnic environment on the International Space Station (ISS): A potential contributing factor to ocular surface symptoms in astronauts.

With increasing advancements and efforts towards space exploration, there is a pressing need to understand the impacts of spaceflight on astronauts' health. Astronauts have reported signs and symptoms of dry eye disease upon traveling to the International Space Station (ISS), thus necessitating an evaluation of the factors that contribute to the onset of spaceflight associated dry eye disease. Prior literature describes the hypercapnic environment of the ISS; however, the link between the high CO levels and astronauts' symptoms of dry eye disease remains unexplored.
