This study presents a novel method for controlling the position and orientation of the bioinspired I-SUPPORT soft robot, which represents a relevant advancement in the field of soft robotics. The approach is based on module actuation decoupling and fractional-order control, offering a more advanced and robust control solution. This innovation enhances the versatility of the robot and illustrates the efficacy of fractional-order controllers, which are comparable to current meta-learning-based controllers. The research involves experiments in both vertical and horizontal configurations, addressing tasks ranging from simple orientation to complex interactions, such as gentle rubbing during bathing activities with the robot. These experimental results exemplify the efficacy of the proposed control strategy and provide a foundation for future research in soft robotics control, underscoring its potential for broader applications and further technological advancement.

Background: Accurate acetabular cup orientation in total hip arthroplasty (THA) is crucial for successful outcomes. Intraoperative fluoroscopy may be used to evaluate acetabular cup placement. This study aimed to evaluate the accuracy of purely visual estimation of cup inclination and anteversion using intraoperative fluoroscopy, considering different surgeon experience levels and cup designs.

Substance misuse among college students continues to rise, with polysubstance use becoming increasingly common. Alcohol remains the most prevalent substance, with heavy episodic and high-quantity drinking linked to serious consequences, including injuries, assaults, and deaths. Concurrent use of alcohol and cannabis, as well as other illicit drugs, further compounds risks to health, safety, and academic functioning.

Diversity-oriented synthesis (DOS) has emerged as an efficient strategy for constructing diverse compound libraries, facilitating hit or lead identification in the drug discovery process. In parallel, developing diverse transformations at different sites is an appealing strategy to expand the diversity of appendages on scaffolds. Owing to the availability of C-H bonds at multiple sites of pharmacophores, diversity-oriented C-H activation reactions are an ideal approach to realize this goal.

Objectives: Left ventricular vortex dynamics play a crucial role in cardiac function but are significantly altered by mitral valve diseases or surgical interventions. Such hemodynamic changes may lead to maladaptive intracardiac vortices, potentially triggering pathways associated with progressive left ventricular remodeling and thrombosis. This study assessed left ventricular hemodynamics under both physiological and pathological conditions using a biohybrid in vitro platform, aiming to analyze the impact of these conditions on cardiac function.

Surgical instrument segmentation plays an important role in robotic autonomous surgical navigation systems as it can accurately locate surgical instruments and estimate their posture, which helps surgeons understand the position and orientation of the instruments. However, there are still some problems affecting segmentation accuracy, like insufficient attention to the edges and center of surgical instruments, insufficient usage of low-level feature details, etc. To address these issues, a lightweight network for surgical instrument segmentation in gastrointestinal (GI) endoscopy (GESur_Net) is proposed.
