Cryogenic quantum computer control signal generation using high-electron-mobility transistors.

Multiplexed local charge storage, close to quantum processors at cryogenic temperatures could generate a multitude of control signals, for electronics or qubits, in an efficient manner. Such cryogenic electronics require generating quasi-static control signals with small area footprint, low noise, high stability, low power dissipation and, ideally, in a multiplexed fashion to reduce the number of input/outputs. In this work, we integrate capacitors with cryogenic high-electron mobility transistor (HEMT) arrays and demonstrate quasi-static bias generation using gate pulses controlled in time and frequency domains.

The Tiber Island in the history of dermatology and venereology, including the curious history of "K syndrome," the fictitious disease that scared the Nazis.

Tiber Island in Rome has a rich history as a center of worship and health care. Its origins date back to ancient times, with the establishment of the Temple of Asclepius marking its role in healing practices. Over centuries, it evolved into a hub for medical innovation and refuge during epidemics and conflicts.

Factors associated with venous thromboembolism pharmacoprophylaxis initiation in hospitalized medical patients: the Medical Inpatients Thrombosis and Hemostasis study.

Background: Although guidelines recommend risk assessment for hospital-acquired venous thromboembolism (HA-VTE) to inform prophylaxis decisions, studies demonstrate inappropriate utilization of pharmacoprophylaxis in hospitalized medical patients. Predictors of pharmacoprophylaxis initiation in medical inpatients remain largely unknown.

Objectives: To determine factors associated with HA-VTE pharmacoprophylaxis initiation in adults hospitalized on medical services.
