A reagent to access methyl sulfones.

A chemical reagent to access methyl sulfones has been developed. Its reaction with various bis-nucleophiles leads to the rapid formation of previously unknown heteroaromatic methyl sulfones. Analogous strategy can also be used to construct alkyl-, CHF-, CF- and even bicyclo[1.

The swinging sclera technique for evisceration.

Purpose: To present a modified evisceration technique with a full-thickness horizontal sclerotomy and assess post-operative motility and long-term outcomes.

Methods: This is a retrospective chart review of patients who underwent evisceration with a single surgeon (TJM). The standard initial steps of evisceration were performed.

Adaptive neural observer-based output feedback anti-actuator fault control of a nonlinear electro-hydraulic system with full state constraints.

This paper proposes an adaptive output feedback full state constrain (FSC) controller based on the adaptive neural disturbance observer (ANDO) for a nonlinear electro-hydraulic system (NEHS) with unmodeled dynamics. The Barrier Lyapunov Functions (BLFs) are utilized to ensure that all states of the system are specified within the constraints, and the approximation ability of radial basis function neural networks (RBFNNs) is used to cope with the unknown nonlinear functions. An adaptive neural compensation disturbance observer is elaborated to estimate the compound disturbance and oil leakage fault, effectively addressing these negative effects.

Perspectives on Conducting Behavioral Intervention With Adolescents Using a Virtual Platform-A Thematic Analysis From the Viewpoint of Study Coordinators.

Background: The COVID-19 pandemic led to widespread adoption of virtual communication platforms. Virtual study visits were implemented in the pilot cluster randomized trial (CRT) stage of Teen Adherence in KidnEy transplant Improving Tracking To Optimize Outcomes (TAKE-IT TOO). The present study aimed to understand study coordinators' perspectives on conducting a behavioral intervention with adolescent kidney transplant recipients using virtual conferencing platforms.
