We demonstrate a memory device based on the nonlinear dynamics of an in-plane microelectromechanical systems (MEMS) clamped⁻clamped beam resonator, which is deliberately fabricated as a shallow arch. The arch beam is made of silicon, and is electrostatically actuated. The concept relies on the inherent quadratic nonlinearity originating from the arch curvature, which results in a softening behavior that creates hysteresis and co-existing states of motion. Since it is independent of the electrostatic force, this nonlinearity gives more flexibility in the operating conditions and allows for lower actuation voltages. Experimental results are generated through electrical characterization setup. Results are shown demonstrating the switching between the two vibrational states with the change of the direct current (DC) bias voltage, thereby proving the memory concept.

Introduction. Middle-ear ventilation tubes are commonly placed in pediatric patients because of the high frequency of otitis media. Although avoidance of water activity has been recommended to prevent otorrhea, studies indicate that exposure to water does not increase these episodes.

Purpose: The impact of body-cavity depth on open (OLR) and laparoscopic liver resection (LLR) of segment 7 remains unclear. Therefore, we investigated the influence of body-cavity depth at the upper-right portion of the abdomen on LLR and OLR of segment 7.
Methods: In total, 101 patients who underwent segment-7 liver resection over 2010-2023 were included.

Background and objective Palatal depth is significant as it impacts the intra-arch dimensions in patients with Angle's Class II Division 1 malocclusion. Hence, understanding this relationship is crucial for developing targeted orthodontic treatment plans, to optimize dental alignment and overall facial aesthetics. This study aimed to compare the arch length, intercanine width, intermolar width, and interalveolar width in patients with Class II Division 1 malocclusion with deep palates and those with shallow palates.

Article Synopsis
- Luffa cylindrica, a climbing herb valued for its nutrition and medicinal properties, is facing a significant decline in health due to root-knot nematode disease, particularly in Beihai, Guangxi, China, where almost 90% of the plants were affected.
- Investigations revealed physical symptoms such as plant dwarfism, decreased yields, and prominent root knotted growth after analyzing the roots of the plants, which highlighted the presence of nematodes at different life stages.
- Morphological characteristics of the identified nematodes, likely Meloidogyne enterolobii, matched previous descriptions, and DNA analysis using specific primers confirmed their presence, showing a targeted amplification of about 236 bp.
Effect of Co-exposure to Additional Substances on the Bioconcentration of Per(poly)fluoroalkyl Substances: A Meta-Analysis Based on Hydroponic Experimental Evidence.

Article Synopsis
- A study was conducted to investigate how the presence of other substances affects the bioconcentration of per(poly)fluoroalkyl substances (PFAS) in hydroponic systems, analyzing 1,085 datasets.
- Results showed that co-exposure to dissolved organic matter significantly reduced PFAS bioaccumulation compared to other substances, indicating a cumulative effect size of -0.4287.
- Additionally, factors such as lower concentrations of other substances (ASs) and longer co-exposure duration were found to influence PFAS bioaccumulation, with longer chains or high fluoride content PFASs being particularly affected.
