Here, we developed a comprehensive therapeutic modality integrating piezoelectric fibrous dressing with controlled ultrasound stimulation for efficient healing in an infected wound model.

A comparative investigation on the extraction-function relationship of polysaccharides derived from moringa oleifera seeds in terms of antioxidant capacity.

Owing to the hypoglycemic, anti-inflammatory, and other beneficial bioactivities of Moringa oleifera seeds (MOS), the antioxidant activities and physicochemical characteristics of deproteinized polysaccharides extracted using hot water (MSWP) and alkali (MSAP) from MOS were systematically studied. MSAP exhibited higher antioxidant activity than MSWP in vitro. Subsequently, the antioxidant capacity was evaluated after oral administration of MSAP in diabetic rats.

A comparison of the therapeutic efficacy of Tenofovir Disoproxil Fumarate and Entecavir in patients with chronic Hepatitis-B.

Objective: To compare the therapeutic efficacy of tenofovir disoproxil fumarate (TDF) and entecavir (ETV) in patients with chronic Hepatitis-B (CHB).

Methods: This retrospective study included 110 patients with CHB who received treatment at The First People's Hospital of Linping District, Hangzhou from January 2021 to January 2023. Clinical data of the patients were reviewed and the patients were classified according to the treatment received: TDF group (n=53, patients received TDF treatment) and ETV group (n=57, patients received ETV treatment).

Chaotic control of a simply supported beam in a multidimensional system.

In this work, a control strategy based on fuzzy sliding mode control (FSMC) is applied to effectively manage the large-amplitude chaotic vibrations exhibited by a simply supported beam. The analysis considers the nonlinear beam structure, which is subjected to an external load. Hamilton's principle is employed, and the equations of motion are derived for the studied structure.

Chaotic vibration control of an axially moving string of multidimensional nonlinear dynamic system with an improved FSMC.

A new control approach based on fuzzy sliding mode control (FSMC) is proposed to regulate the chaotic vibration of an axial string. Hamilton's principle is used to formulate the nonlinear equation of motion of the axial translation string, and the von Kármán equations are used to analyse the geometric nonlinearity. The governing equations are nondimensionalized as partial differential equations and transformed into a nonlinear 3-dimensional system via the third-order Galerkin approach.

The influence of lumped mass deployment on the performance of a hybrid galloping energy harvester.

This article delves into a hybrid galloping energy harvester featuring a longitudinally aligned triangular-shaped bluff body. Numerically, it analyzes how the position of a lumped mass influences the average output power of the harvester under concurrent base excitation and galloping. In comparison with traditional hybrid energy harvesters, the impact of three factors-low airflow velocity, small base excitation amplitude, and low frequency-is examined for each case of lumped mass deployment.
