Effect of Conical Profile on the Transmission of Elastic Waves From Cylindrical Waveguide to Bulk

This paper studies the transmission of elastic waves into test specimens for cylindrical waveguide-based ultrasonic transducers. However, to achieve better mode focusing, topographical waveguides with conical profiles were studied. Finite element simulations were used to study wave propagation and transmission into specimen samples using such “transmission horns.” Fundamental longitudinal mode L(0,1) was generated in cylindrical rods. Results from both finite element simulations and experiments show that a 50-deg conical transition profile help achieve better transmission and beam directionality into the specimen and also better reception of the back wall reflections at the waveguide as compared to a simple cylindrical rod waveguide.

Manipulating the helix–coil transition profile of synthetic polypeptides by leveraging side-chain molecular interactions

Based on the pH-sensitive, conformationally tunable triazole polypeptides, we reported the manipulation of helix–coil transition profile determined by the leveraging interactions of the triazole and other side-chain helix-influencing ligands.

The use of the Rotterdam Transition Profile: 10 years in review

The aim of this literature review was to describe the use and utility of the Rotterdam Transition Profile (RTP), as we near the tenth year since its publication in 2008. It is a tool to summarize a youth’s transition process to adulthood by classifying various domains of participation and health care into developmental stages. This review provided a comprehensive synthesis of available knowledge on the RTP by summarizing published and grey literature. Using search terms related to transition, social participation, and questionnaire, a systematic search was conducted for literature up to November 2017 in MEDLINE and Embase databases, and was supplemented with a hand-search using Google Scholar and a general internet search using Google Search. Inclusion criteria were specified to determine the papers selected for review, yielding fifty-five materials for detailed review. Combined analysis of published and grey literature identified nine papers that used some form of the RTP as a measure, 18 materials that cited the RTP or its domains but did not employ it as a measure, and twenty-eight materials that cited the original RTP development and validation paper for information not directly related to the RTP. The literature demonstrated that the RTP seems to be a useful tool to describe and monitor the transition process of adolescents and young adults, in both research and clinical settings. While it has been used with youth of 14–31 years of age across genders and health conditions, more evidence is needed to demonstrate its psychometric properties beyond construct validity in young adults with cerebral palsy.
