This paper presents a new small-signal model for double-channel (DC)-high-electron-mobility transistors, developed through an analysis of the unique coupling effects between channels in devices. Unlike conventional single-channel HEMTs, where electrons only transport laterally channel, DC-HEMTs exhibit additional vertical two along material direction. effect significantly limits applicability traditional models to DC-HEMTs. Firstly, is characterized by introducing sub-model, which consists...
Abstract To enhance the electrochromic(EC) properties of WO 3 thin films, The ITO/PET substrate was modified with Pt sputtering. Subsequently, nanostructured films were deposited on via DC magnetron sputtering at a glancing angle 80°.

Sulfonyl groups are motifs that widely found in biologically active compounds and drug molecules, many isolated natural products as well pharmaceuticals contain sulfonyl groups. Herein, we present the synthesis of sulfonyl-substituted isoindolones by a electrochemical oxidative radical cascade cycloaddition reaction olefinic amides with sodium sulfite under oxidant- catalyst-free conditions. Various sulfinates were compatible gave desired yields up to 99%.
The incidence of hypertriglyceridemia (HTG)-induced acute pancreatitis (AP) is steadily increasing in China, becoming the second leading cause AP. Clinical complications and outcomes associated with HTG-AP are generally more severe than those seen AP caused by other etiologies. closely linked to metabolic dysfunction frequently coexists syndrome or its components. However, impact components on clinical remains unclear.
Abstract Introduction Walking stands as the most prevalent physical activity in daily lives of individuals and is closely associated with functioning aging process. Nonetheless, precise cause-and-effect connection between walking remains unexplored. The epigenetic clock emerges promising biological indicator aging, capable mirroring age human body facilitating an investigation into association aging. Our primary objective to investigate causal impact acceleration (EAA). Methods We conducted...
ABSTRACT Honeysuckle, a traditional Chinese medicine, holds significant medicinal value, making it ubiquitous in the medical field. However, efficient extraction of chlorogenic acid from herbal medicine while maintaining its pharmacological activity remains pressing challenge. To address issues environmental pollution and inefficient using solvents, there is need to develop novel solvent. Due their low cost, nontoxic, environmentally friendly characteristics, deep eutectic solvents can be...
