Eynard-Mehta theorem, Schur process, and their pfaffian analogs
We give simple linear algebraic proofs of Eynard-Mehta theorem,
Okounkov-Reshetikhin formula for the correlation kernel of the Schur process,
and Pfaffian analogs of these results. We also discuss certain general
properties of the spaces of all determinantal and Pfaffian processes on a given
finite set.Comment: AMSTeX, 21 pages, a new section adde
Design of an asymmetrical rotor for easy assembly and repair of field windings in synchronous machines
This paper introduces a new asymmetrical rotor design for easy assembly and repair of field windings in synchronous machines. A new rotor geometry is adopted in order to simplify the manufacture and maintenance process of installing the rotor windings. The asymmetrical rotor design is simulated by the 2-D finite element analysis (FEA), and verified by experimental tests on a 27.5 kVA prototype machine. The proposed topology can drive down the maintenance and repair costs of the machine without impacting on the machine’s electro-magnetic performance. This design will have significant economic implications for machine design and repair industry, especially for mass production markets such as wind turbines and engine-generators

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries
Background
Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres.
Methods
This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries.
Results
In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia.
Conclusion
This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Human papillomavirus vaccine information, motivation, and behavioral skills among young adult US women
PubMedID: 28810358This study elicited the information needs, motivations, and behavioral skills related to human papillomavirus vaccine decision-making among young adult women. Interviews were conducted with college women, aged 18–26 years, and stratified by recently vaccinated (N = 25) and unvaccinated (N = 25). Comparative thematic analysis using the Information, Motivation, and Behavioral Skills Model was conducted. Healthcare providers were identified as the most trusted sources for information. While unvaccinated women did not have experience receiving the vaccine, they reported the same procedural knowledge for vaccination. These findings suggest that young adult women have the information and procedural knowledge for human papillomavirus vaccination, but motivations may influence their decision-making. © The Author(s) 2016.University of South FloridaThe author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This study was supported through student research grants from the Department of Community and Family Health at the University of South Florida

Report of Technical Committee V.6 of ISSC2006: Condition assessment of aged ships
Committee mandate: Concern for the development of methods for assessing the serviceability and safety of aged
steel ships. This shall include assessment of the structural condition (in view of corrosion,
fatigue cracking and local denting), methods for repair, quantification of strength of
deteriorated and repaired ships (as well as criteria for acceptable damage), with due account
of the uncertainties involved. Consideration shall be given to cost-benefit and risk-based
decision procedures for remedial actions
