Transcranial Magnetic Stimulation Inter-Pulse Interval Does Not Influence Corticospinal Excitability to the Biceps Brachii During Submaximal Isometric Elbow Flexion.

Previous research on resting muscles has shown that inter-pulse interval (IPI) duration influences transcranial magnetic stimulation (TMS) responses, which can introduce serious confounding variables into investigations if not accounted for. However, it is far less clear how IPI influences TMS responses in active muscles. Thus, the purpose of this study was to examine the relationship between IPI and corticospinal excitability during submaximal isometric elbow flexion.

Aerobic exercise has been shown to impact corticospinal excitability (CSE), however the mechanism(s) by which this occurs is unclear. Some evidence suggests an increase in blood lactate concentration resulting from exercise may be what is driving these changes in corticospinal excitability. The extent of literature examining this effect and whether it is consistent across the literature is unknown.

Article Synopsis
- Extended ligand conjugation improves luminescent thermometry in Dy-based single-molecule magnets (SMMs) through crystallographic, photoluminescence, and lifetime decay studies.
- This enhancement allows for effective energy transfer from the ligands to the Dy metal centers.
- The results show a significant excited-state lifetime of Dy(III), indicating efficient interactions due to the ligand modifications.
Chemical Origins of Optically Addressable Spin States in Eu(PS) and Eu(PSe).

Lanthanide materials with a 4f electron configuration (S) offer an exciting system for realizing multiple addressable spin states for qubit design. While the S ground state of 4f free ions displays an isotropic character, breaking degeneracy of this ground state and excited states can be achieved through local symmetry of the lanthanide and the choice of ligands. This makes Eu attractive as it mirrors Gd in exhibiting the S ground state, capable of seven spin-allowed transitions.

Nonvolatile control of spin order or spin excitations offers a promising avenue for advancing spintronics; however, practical implementation remains challenging. In this Letter, we propose a general framework to realize electrical control of magnons in 2D magnetic insulators. We demonstrate that in bilayer ferromagnetic insulators with strong spin-layer coupling, the electric field can effectively manipulate the spin exchange interactions between the layers, enabling nonvolatile control of the corresponding magnons.
