Climbing as a competition sport has become increasingly popular in recent years, particularly the sub-discipline of bouldering. The sport will debut in the Tokyo Summer Olympic Games. National and international competitions have three disciplines: lead (climbing with rope protection), bouldering (climbing at lower heights with mattress floor protection) and speed (maximum speed climbing on a standardised route in 1-on-1 mode). There is also a ‘combined mode’ of all three disciplines (combined) which forms the Olympic competition format; all competition formats are held on artificial walls. Existing literature describes a predominantly low injury frequency and severity in elite climbing. In comparison to climbing on real rock, artificial climbing walls have recently been associated with higher injury rates. Finger injuries such as tenosynovitis, pulley lesions and growth plate injuries are the most common injuries. As finger injuries are sport-specific, medical supervision of climbing athletes requires specific medical knowledge for diagnosis and treatment. There is so far little evidence on effective injury prevention measures in top athletes, and antidoping measures, in general, requiring further work in this field. An improved data situation regarding high-performance climbing athletes is crucial to ensure that the sport continues to be largely safe and injury-free and to prevent doping cases as extensively as possible.

The purpose of this article is to describe recent actions for sport organizations and coach development in Finland. Finnish Sport organizations and systems especially in high-performance sports have been in a transition phase in recent years. The high-performance sport systems have been analyzed and reorganized and new strategic goals were set. Coach development was chosen as one of the focus areas and the leadership of coach development is at the new High Performance Unit of the Olympic Committee. There are different education paths for coaches and all the organizations which provide coach education belong to a network for coach development. This network works for developing programs, learning concepts and tools and sharing of expertise. One key idea of the development work has been to conduct systematic research among Finnish coaches to gain objective information of coaches’ needs and learning experiences. As a result of this work, the Finnish Coach Competence Model was created as a tool and for creating common understanding of coaches’ competences and for developing education programs and coaches’ assessment. Creating a new learning culture and a network have been the main steps so far and the further development for those are also the main goals in future.

Recent advances in simulation optimization research and explosive growth in computing power have made it possible to optimize complex stochastic systems that are otherwise intractable. In the first part of this paper, we classify simulation optimization techniques into four categories based on how the search is conducted. We provide tutorial expositions on representative methods from each category, with a focus in recent developments, and compare the strengths and limitations of each category. In the second part of this paper, we review applications of simulation optimization in various contexts, with detailed discussions on health care, logistics, and manufacturing systems. Finally, we explore the potential of simulation optimization in the new era. Specifically, we discuss how simulation optimization can benefit from cloud computing and high-performance computing, its integration with big data analytics, and the value of simulation optimization to help address challenges in engineering design of complex systems.

The rapid growth of data collection has led to a new era of information. Data is being used to create more efficient systems and this is where Recommendation Systems come into play. Recommender systems are among the most effcient tools for information filtering to improve the quality of search results and provide items that are more relevant to the search item or are realted to the search history of the user, especially from big data on Internet. Among those, movie recommendation systems are the useful tools to assist users in classifying them with similar interests. This makes them a central part of websites and e-commerce applications. This paper aims to describe the implementation of a movie recommender system built on the Wordpress platform to be able to take advantage of the plugin support system and outstanding management and statistical features. The obtained results indicate that the proposed approach may provide high performance regarding reliability, efficiency, and accuracy. Moreover, the user-friendly interface and suitable display for devices ranging from desktop to mobile devices are also the advantages.

AbstractBackgroundEnvironmental DNA (eDNA) and metabarcoding, allow the identification of a mixture of individuals and launch a new era in bio- and eco-assessment. A number of steps are required to obtain taxonomically assigned (Molecular) Operational Taxonomic Unit ((M)OTU) tables from raw data. For most of these, a plethora of tools is available; each tool’s execution parameters need to be tailored to reflect each experiment’s idiosyncrasy. Adding to this complexity, for such analyses, the computation capacity of High Performance Computing (HPC) systems is frequently required.Software containerization technologies ease the sharing and running of software packages across operating systems; thus, they strongly facilitate pipeline development and usage. Likewise are programming languages specialized for big data pipelines, incorporating features like roll-back checkpoints and on-demand partial pipeline execution.FindingsPEMA is a containerized assembly of key metabarcoding analysis tools with a low effort in setting up, running and customizing to researchers’ needs. Based on third party tools, PEMA performs reads’ pre-processing, clustering to (M)OTUs and taxonomy assignment for 16S rRNA and COI marker gene data. Due to its simplified parameterisation and checkpoint support, PEMA allows users to explore alternative algorithms for specific steps of the pipeline without the need of a complete re-execution. PEMA was evaluated against previously published datasets and achieved comparable quality results.ConclusionsGiven its time-efficient performance and its quality results, it is suggested that PEMA can be used for accurate eDNA metabarcoding analysis, thus enhancing the applicability of next-generation biodiversity assessment studies.

Abstract Induction motors have been widely used in the ESP industry for decades. Motor operation, control, and optimization are well-understood topics among providers and final consumers, who strive to get the most efficient electrical machine in the well to reduce power consumption and, consequently, operating expenses. This paper presents a case study for a newly redesigned induction motor and changes made in its design and construction. A field trial of two wells deployed with the new motor and a comparison with a well deployed with the standard motor are described. Field and simulated data are used to analyze the electrical performance and power consumption. The test results included are from wells in the US Rocky Mountains. Additionally, some of the motors in this test were manufactured with a high-performance thermally conductive and electrically insulative windings encapsulation, which is further discussed in the paper. The increased efficiency was achieved through an optimized electromagnetic design that helped to reduce the motor total losses. Efficiency gains were measured against standard motor design through laboratory testing, and the result showed 2.2 to 2.5% higher efficiency for the newly developed motor. With the higher power density, the motor length was shortened from 20 to 25% during the field trials, reducing the total length of the string. In addition to the optimization of motor length, the newly redesigned motor generates a lower core temperature when compared to a previous motor of the same length and subjected to the same load. This fact allows the motor to be loaded up to 25% above its nameplate rating, improving the horsepower rating and opening a new era for highly flexible induction motors. The gathered results showed that the newly redesigned motor provides higher efficiency and lower total electrical power consumption compared to the standard induction motor that would have been used in those applications. Both results were evidenced in controlled laboratory testing and field trials. A further comparison of similar ESP equipment configuration running with former motor versions is also provided, as well as design comparison cases between the expected results of the previous and the newly designed motor.
