Hybrid superconductor-semiconductor Josephson field-effect transistors (JoFETs) function as Josephson junctions with gate-tunable critical current. Additionally, they can feature a non-sinusoidal current-phase relation (CPR) containing multiple harmonics of the superconducting phase difference, a so-far underutilized property. Here we exploit this multi-harmonicity to create a Josephson circuit element with an almost perfectly π-periodic CPR, indicative of a largely dominant charge-4e supercurrent transport.

Here, we report a gatemon device featuring an aluminum microwave circuit on a Ge/SiGe heterostructure embedding a Ge quantum well. Owing to the superconducting proximity effect, the high-mobility two-dimensional hole gas confined in this well provides a gate-tunable superconducting weak link between two Al contacts.

- The study investigates the relationship between CEACAM1 levels and insulin metabolism in individuals with Type 2 diabetes and obesity.
- Findings show that as insulin resistance and hyperinsulinemia increase, CEACAM1 levels decrease, particularly in those with prediabetes and Type 2 diabetes.
- The results suggest that measuring circulating CEACAM1 could serve as a useful biomarker for assessing metabolic health and insulin clearance.
Article Synopsis
- * There were five in-hospital deaths among ICU patients (3.5% fatality rate) compared to three in non-ICU patients (0.1%), indicating significantly higher risks for those admitted to ICUs.
- * Significant factors leading to ICU admission included obesity, diabetes, pneumonia, ARDS, and other comorbidities, highlighting the importance of existing health conditions in pediatric COVID-19 cases.
Article Synopsis
- This study examines the challenges faced by Venezuelan migrants and refugees in Peru, focusing on their integration and access to decent work.
- Data were collected from 1,193 individuals seeking help from an NGO, highlighting issues related to "brain waste," where educated migrants cannot fully apply their skills in the job market.
- The findings emphasize the urgent need for public policies to improve the living conditions of these migrants and promote better employment opportunities.
