Summary: The discovery of new mechanisms for controlling magnetic properties using electric fields or currents provides a deeper understanding of magnetism and has important practical implications. In this study, we propose a method of using resistive switching to control magnetic anisotropy. We investigate a ferromagnetic oxide that undergoes an electrically triggered metal-to-insulator phase transition, resulting in volatile resistive switching. Our results demonstrate that resistive switching is an effective tool for manipulating magnetic properties and could lead to the development of a new class of voltage-controlled magnetism systems.

Summary: A novel design of flexible resistive tactile sensor was proposed, utilizing conductive graphite paint and conductive silver paint as sensing materials. The output signal depends on the contact area between the high-impedance and low-impedance elements caused by applied pressure, employing the short-circuit effect for the transduction mechanism. The sensor showed a wide range of pressure response up to above 3 MPa and demonstrated potential applications in teleoperation and letter recognition.

Summary: The appearance of twin/stacking faults in nanoparticles affects their catalytic, optical, and electrical properties. However, there is a lack of experimental tools for characterizing these defects numerically, leading to poor understanding of structure-property correlations. In this study, we explored the twinning effect on XRD pattern and developed a new approach based on the mutual orientation of periodic fcc segments. By performing computational simulations, we found a correlation between the number of domains and the height ratio of 220 to 111 diffraction peaks. Our XRD analysis of Au and AuPt samples, compared with TEM and SAXS analyses, demonstrates the potential of our multidomain XRD method in studying structure-property correlations in nanomaterials.

Summary: This study explores the effects of posterior supplemental fixation on facet micromotions, cage loads, and load-patterns at adjacent levels in a L4-L5 XLIF procedure. The results indicate that the extent of posterior fixation is closely related to the reduction of loads and micromotions at the index-level facets, while changes in load-patterns at adjacent facets may vary anatomically. Unilateral fixation provides similar stability compared to bilateral, with the added benefit of reducing stress-risers on the cage. This study highlights the importance of considering posterior supplemental fixation in combination with clinical information.

Summary: This paper presents an experimental characterization of a proposed radio link model for an underground mine sensor network. Power efficiency and range are critical considerations when designing a wireless sensor network for low data rate applications in underground mines. A radio link model was developed and evaluated specifically for 433 MHz DASH7 in underground mines, considering the practical electromagnetic properties of mine walls and the propagation medium. The model utilizes the received signal strength indicator (RSSI) and packet error rate (PER) to measure wave propagation and assess the quality of the radio link, leading to improved performance and reliability in complex mine structures.

Summary: This study proposes a NEMS-based piezoresistive pressure sensor using a twin JL-NW GAA FET on a circular diaphragm for highly sensitive measurement. The maximum sensitivity is observed in the subthreshold regime, which is 4 times higher than in the ON-state conditions. However, the sensitivity is reduced by 4.5% and 14.7% in the ON-states and subthreshold regime, respectively, due to a slight mobility reduction caused by temperature increase. Despite this, the environmental temperature does not significantly dominate the sensor's performance, making the JL-NW GAA FET a promising piezoresistive sensor in NEMS.
