Controlling spin-polarized currents at the nanoscale is of immense importance for high-density magnetic data storage and spin-based logic devices. As electronic devices are miniaturized to the ultimate limit of individual atoms and molecules, electronic transport is strongly influenced by the properties of the individual spin centers and their magnetic interactions. In this work, we demonstrate the precise control and detection of spin-polarized currents through two coupled spin centers at a tunnel junction by controlling their spin-spin interactions.

Lanthanide atoms show long magnetic lifetimes because of their strongly localized 4 electrons, but electrical control of their spins has been difficult because of their closed valence shell configurations. We achieved electron spin resonance of individual lanthanide atoms using a scanning tunneling microscope to probe the atoms bound to a protective insulating film. The atoms on this surface formed a singly charged cation state having an unpaired 6 electron, enabling tunnel current to access their 4 electrons.

Background: This study compares 2 minimally invasive coronary revascularization approaches: robot-assisted multivessel minimally invasive direct coronary artery bypass (MIDCAB) and the hybrid approach combining MIDCAB with subsequent percutaneous coronary intervention.

Methods: A retrospective review was conducted on cases of robotic MIDCAB performed at our institution between 2012 and 2022. Two groups of patients were analyzed: the surgery group (undergoing robotic multivessel MIDCAB) and the hybrid group.

Article Synopsis
  • Variants associated with neurodevelopmental impairments in children are complex and challenging to evaluate due to their diverse nature and unclear causes.
  • The study highlights a case of a child with neonatal-onset epilepsy and a specific genetic variant (G256W) that impacts ion channel function and leads to reduced cell stability and conduction in nervous tissue.
  • The research also establishes a mouse model that exhibits epilepsy and hyperexcitability in brain cells, linking the genetic variant to observable neurological behaviors and suggesting potential wider implications for understanding similar conditions in other patients.

Background: The co-occurrence of anterior cruciate ligament (ACL) rupture with medial collateral ligament (MCL) rupture is a compound injury that can be associated with meniscal tears.

Purpose: To report the characteristics of meniscal tears in knees with isolated ACL versus combined ACL and MCL injuries, analyzing their frequency, distribution by site, and lesion type.

Study Design: Cross-sectional study; Level of evidence, 3.
