AI Article Synopsis
- - A new thin single-phase drive linear ultrasonic motor is developed, featuring switchable driving modes for bidirectional operation, allowing it to move in both right and left directions.
- - The motor's design, functionality, and dynamic performance are analyzed through a finite element model, followed by real-world testing of a prototype, which shows promising vibration characteristics.
- - With a maximum no-load speed of approximately 159.7 mm/s and thrust forces around 2.5 N and 2.1 N for each direction under specific conditions, this lightweight motor offers excellent performance and represents a novel approach to creating efficient ultrasonic actuators.
Article Abstract
A novel thin single-phase drive linear ultrasonic motor is proposed and tested in this paper. The proposed motor exhibits bidirectional driving via switching between the right-driving vibration mode (RD mode) and the left-driving vibration mode (LD mode). The structure and working principle of the motor are analyzed. Next, the finite element model of the motor is established and the dynamic performance is analyzed. A prototype motor is then fabricated, and its vibration characteristics are established via impedance testing. Finally, an experimental platform is built and the mechanical characteristics of the motor are experimentally investigated. The maximum no-load speed of the motor is ∼159.7 mm/s. With 8 N preload and 200 V voltage, the maximum thrust force of the motor in the RD and LD modes are ∼2.5 and 2.1 N, respectively. The motor possesses the advantages of being light in weight and thin structure and exhibiting an excellent performance. This work presents a new concept for the construction of ultrasonic actuators with bidirectional driving capacity.

Habilitation studio "The Little Prince", Municipal autonomous institution of additional education, "Children and Youth Center of the Frunzensky district of Saratov", Saratov, Russia.
The purpose of this study was to investigate the sleep characteristics, circadian rhythms, behavior, and postnatal development of children with and without language difficulties (LDs) and the association of these variables with melatonin-containing food (FMT) consumption. The study involved parents who anonymously and voluntarily provided their children's personal data and assessed LDs, bedtime, meal timing, behavioral problems, gross motor skill development, and FMT consumption. Multiple regression analysis was used to analyze the associations between study variables.

Aim: To explore the effectiveness and safety of Osborne's ligament suspension and ulnar nerve anterior transposition (OLSUNAT) in conjunction with transcutaneous electrical nerve stimulation (TENS) for managing cubital tunnel syndrome (CTS).
Methods: A total of 116 individuals diagnosed with CTS who underwent OLSUNAT in our hospital between October 2020 and December 2023 were retrospectively selected. They were divided into a treatment group (62 cases) and a control group (54 cases) based on whether they received subsequent TENS.

Motor symptom laterality is an important clinical feature of PD that not only manifests as lateral limb dysfunction but also affects the nonmotor symptoms and the prognosis in PD patients. Previous studies suggested that the compensatory mechanisms in the dominant hemisphere of the brain may be an underlying explanation. The corpus callosum (CC) is the largest fiber connecting the two hemispheres of the brain.

Introduction: Spinal cord injury (SCI) is a severe neurological disease characterized by significant motor, sensory, and autonomic dysfunctions. SCI is a major global disability cause, often resulting in long-term neurological impairments due to the impeded regeneration and remyelination of axons. A SCI interferes with communication between the brain and the spinal cord networks that control neurological functions.
