Fuzzy-PI Torque and Flux Controllers for DTC with Multilevel Inverter of Induction Machines

, 2014
In this paper the performance of flux and torque controller for a Direct Torque Control of Cascaded H-bridge Multilevel Inverter (DTC-CMLI) fed induction machines are investigated. A Fuzzy-PI with fixed switching frequency is proposed for both torque and

Prevalence and Patterns of Multiple Injuries Affecting a Single Permanent Tooth (Combination Injuries): A Systematic Review and Meta‐Analysis

Dental Traumatology, EarlyView.
ABSTRACT Background Combination injuries or multiple traumatic dental injuries (TDI) affecting a single permanent tooth are clinically significant but remain underrecognized. Although the global prevalence of TDI is well documented, the epidemiology of combination injuries has not been clearly established. This systematic review and meta‐analysis aimed

Effect of chitosan‐containing desensitizers applied prior to bleaching on the physical properties of enamel

European Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effects of adding chitosan (Chi) to desensitizing agents applied before dental bleaching on enamel properties. Bovine enamel specimens were allocated to seven groups (n = 12): no treatment (negative control), 2% NaF (positive control), 2% NaF + 2% Chi, 2% NaF + 5% Chi, 2% NaF + 5% KNO3, 2% NaF + 5% KNO3 + 2 ...

UV signature mutation hyperhotspots as genomic dosimeters

Photochemistry and Photobiology, EarlyView.
Recurrent UV signature mutations are a sensitive and specific indicator of sun exposure. UV signature mutations (C → T mutations at dipyrimidine sites) were quantified using Duplex Sequencing and a stringent mutation calling protocol to identify true low‐abundance mutations.

No evidence of higher peak heat tolerance in the afternoon or with opportunity for thermal behaviour during low‐intensity work in uncompensable heat

Experimental Physiology, EarlyView.
Abstract Heat tolerance is known to be limited by high brain temperature, but most findings pertain to strenuous exercise following artificially altered baseline temperature or with limited opportunity for behaviour. Therefore, we investigated the hypotheses that thermal perceptions, hyperventilation and cerebrovascular responses would be exacerbated ...

Sex differences in macrovascular responsiveness: Acute effects of hot water immersion versus aerobic exercise in overweight older adults

Experimental Physiology, EarlyView.
Abstract Recent studies have focused on the potential benefits of heat exposure for cardiovascular health. However, the acute effects of heat therapy on conduit arteries remain unclear, particularly in overweight and obese older males and females. This study aimed to compare core temperature (Tc), heart rate (HR), and brachial, femoral, and carotid ...

Surface Ligand Engineering in Quantum Dot Photocatalysis: Mechanisms, Design Principles, and Applications

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
Surface ligands govern quantum dot photocatalysis through thermodynamic band‐edge tuning, kinetic charge‐transfer regulation, and microenvironmental control. Rational ligand engineering, using short‐chain, inorganic, conjugated, or dual‐ligand systems, enables efficient solar fuel production, selective organic transformations, environmental remediation,
