A spin wave driven skyrmion-based diode on a T-shaped nanotrack.

The propagation of spin waves is one of the promising ways to design nanoscale spintronic devices. The spin waves can interact with the magnetic skyrmion, a particle-like object that is topologically stabilized by Dzyaloshinskii-Moriya interaction (DMI) in thin film heterostructures. In this work, a spin wave-driven skyrmion-based diode is proposed by employing a T-shaped ferromagnetic nanotrack.

Economic Hardships in Managing COVID-19 Patients in the Intensive Care Unit: A Retrospective Observational Study at a Tertiary Care Hospital in North India.

Background: The information on healthcare expenditure is crucial to know the impact of the pandemic on public health budgets, thereby correctly managing the ongoing crisis and preparing for subsequent waves.

Objective: To estimate the length of stay and cost incurred on COVID-19 patients who died in the ICU.

Methods: It is a record-based descriptive study conducted on 76 deceased COVID-19 patients admitted to the ICU of a dedicated COVID-19 hospital (DCH) between April and October 2020.
