NEMS generated electromechanical frequency combs.

This paper presents a novel technique for low-power generation of frequency combs (FC) over a wide frequency range. It leverages modal interactions between electrical and mechanical resonators in electrostatic NEMS operating in air to provide a simple architecture for FC generators. A biased voltage signal drives the electrical resonator at resonance which is set to match an integer submultiple of twice the mechanical resonator's resonance.

Superior mesenteric artery syndrome in a pediatric patient: A rare case report and literature review.

Introduction And Importance: Superior mesenteric artery (SMA) syndrome, or aorto-mesenteric clamp syndrome, is a rare condition where the third portion of the duodenum is compressed between the aorta and the superior mesenteric artery. This syndrome often affects adolescents and young adults, with predisposing factors including significant weight loss, anatomical variations, and spinal deformities. Early diagnosis and intervention are critical for managing symptoms and preventing complications.

Impact of sodium-glucose cotransporter inhibitors in acute coronary syndrome patients on endothelial function and atherosclerosis related-biomarkers: ATH-SGLT2i pilot study.

Little is known about the effects of sodium-glucose co-transporter 2 inhibitors (SGLT2i) on atherosclerosis. We aimed to determine if a 90-day intake of Dapagliflozin could improve atherosclerosis biomarkers (namely endothelial function assessed by flow-mediated dilatation [FMD] and carotid intima-media thickness [CIMT]) in diabetic and non-diabetic acute coronary syndrome (ACS) patients when initiated in the early in-hospital phase. ATH-SGLT2i was a prospective, single-center, observational trial that included 113 SGLT2i naive patients who were admitted for ACS and who were prescribed Dapagliflozin at a fixed dose of 10 mg during their hospital stay for either type 2 diabetes or for heart failure.

Unveiling the Reaction Mechanism of Diels-Alder Cycloadditions between 2,5-Dimethylfuran and Ethylene Derivatives Using Topological Tools.

The [4+2] Diels-Alder cycloaddition reaction between 2,5-DMF (1) and ethylene derivatives (2a-h) activated by electron-withdrawing groups has been studied at the density functional theory levels using a panoply of tools to unravel the reaction mechanisms. From the analysis of the reactivity indices, 2a-h behave as electrophiles while 1 as nucleophile, and the activation of the double bond of ethylene increases its electrophilicity, which is accompanied by an enhancement of the polarity of the reaction. The activation Gibbs free energy decreases linearly as a function of this increase of polarity, as estimated by the electrophilicity difference between the reactants.
