The integrity of science and engineering research is grounded in assumptions of rigor and transparency on the part of those engaging in such research. HPC community effort to strengthen rigor and transparency take the form of reproducibility efforts. In a recent survey of the SC conference community, we collected information about the SC Reproducibility Initiative activities. We present the survey results in this paper. Results show that the reproducibility initiative activities have contributed to higher levels of awareness on the part of SC conference technical program participants, and hint at contributing to greater scientific impact for the published papers of the SC conference series. Stringent point-of-manuscript-submission verification is problematic for reasons we point out, as are inherent difficulties of computational reproducibility in HPC. Future efforts should better decouple the community educational goals from goals that specifically strengthen a research work’s potential for long-term impact through reuse 5-10 years down the road.

AbstractSleep is a key phenomenon to both understanding, diagnosing and treatment of many illnesses, as well as for studying health and well being in general. Today, the only widely accepted method for clinically monitoring sleep is the polysomnography (PSG), which is, however, both expensive to perform and influences the sleep. This has led to investigations into light weight electroencephalography (EEG) alternatives. However, there has been a substantial performance gap between proposed alternatives and PSG. Here we show results from an extensive study of 80 full night recordings of healthy participants wearing both PSG equipment and ear-EEG. We obtain automatic sleep scoring with an accuracy close to that achieved by manual scoring of scalp EEG (the current gold standard), using only ear-EEG as input, attaining an average Cohen’s kappa of 0.73. In addition, this high performance is present for all 20 subjects. Finally, 19/20 subjects found that the ear-EEG had little to no negative effect on their sleep, and subjects were generally able to apply the equipment without supervision. This finding marks a turning point on the road to clinical long term sleep monitoring: the question should no longer be whether ear-EEG could ever be used for clinical home sleep monitoring, but rather when it will be.

Nowadays, the age of most transport facilities in Russian Federation is estimated in many decades. Consequently, there is an urgent need for periodic surveys and monitoring of the state of each structure, its individual structural elements. The main purpose of these measures is to maintain the high performance indicators of the transport structure, the achievement of which is impossible without examination, analysis and evaluation of parts of the structure that are in the aquatic environment and, as a consequence, the occurrence and development of various types and degrees of defects and damages. The most important conditions for ensuring uninterrupted and safe traffic along the bridges of vehicles and pedestrians are: the normative load-carrying capacity of the structure; required clearance of the roadway and sidewalks; compliance with traffic safety requirements for bridges; observance of characteristics and maintenance of the bridge capacity for the period of ice drift and high water; timely performance of work on the care, maintenance and repair of the elements of the bridge. Technically sound structures and their reliability can be ensured if all the parameters of the road category structure and the requirements of regulatory documents are met. The work presents the survey materials of the bridge. Classification of defects by group and class of danger. The results of determining the carrying capacity on the basis of the survey are given.

External organizations offer schools projects with different content, so-called external school projects. This type of external projects is mainly implemented by people or an organization outside of the school. The projects may be within the framework of a nation's political aspirations. The educational goals of the projects are often far-reaching, focusing on personality or attitudes. This article questions whether external school projects can achieve such far-reaching goals. The aim of the research is to explore the views of young adults regarding how participating in an external project influenced them. In-depth interviewing were used when eleven young adults, at the time 25 years old, were asked about their opinions of an external project in entrepreneurship , implemented as an optional course, ten years after taking part. They were asked how they considered the course have influenced them, their choices and their attitudes. The statements of the informants show that the project had some long-term impact. The results of the research provide insight into whether an external temporary school project may have long-term educational values.

With the continuous expansion of single cell biology, the observation of the behaviour of individual cells over extended durations and with high accuracy has become a problem of central importance. Surprisingly, even for yeast cells that have relatively regular shapes, no solution has been proposed that reaches the high quality required for long-term experiments for segmentation and tracking (S&T) based on brightfield images. Here, we present CellStar , a tool chain designed to achieve good performance in long-term experiments. The key features are the use of a new variant of parametrized active rays for segmentation, a neighbourhood-preserving criterion for tracking, and the use of an iterative approach that incrementally improves S&T quality. A graphical user interface enables manual corrections of S&T errors and their use for the automated correction of other, related errors and for parameter learning. We created a benchmark dataset with manually analysed images and compared CellStar with six other tools, showing its high performance, notably in long-term tracking. As a community effort, we set up a website, the Yeast Image Toolkit, with the benchmark and the Evaluation Platform to gather this and additional information provided by others.

This study analyzes the academy-run enterprises (AREs) in China, which have played an important role in the development of high-tech industries in China, but have rarely been deeply addressed in previous studies. The AREs, despite ostensibly sharing some similarities with the academic spin-offs (ASOs) found in other countries, have distinct historical origins and characteristics in China. In this study, we try to clarify the distinct features of Chinese AREs, particularly in terms of their relationship with their mother institutions, using questionnaire survey data collected from 102 AREs and subsequent follow-up interviews with the ARE managers. This study finds that, while the AREs have enjoyed an exclusive right to exploit various assets of their mother institutions, they have suffered from the interventions of the mother institutions and ambiguous property right arrangements with the mother institutions. More recently, AREs have begun to evolve in response to the changing environment. Furthermore, recently initiated reform measures are expected to accelerate this evolution. Using the survey results, this study assesses the short-term and long-term impact of the reform on Chinese AREs, and the subsequent impact on the academia-industry relationship and the national innovation system (NIS) in China.

Law of Republic Indonesia Number 6 of 2014 concerning Villages as one of development policy raises an implication in the budgeting system, namely the emergence of The Village Funds (VF) and Village Fund Allocation (VFA) in the components of the Village Budget (APBDes). One of the objectives of the Village Law through VF and VFA is to ensure that basic infrastructure such as roads, canals, dikes, electricity and clean water in the village have been fulfilled so as to be able to support the smooth economic activities of the village. The road which is one of the basic infrastructure related to transportation and accessibility is key in the economy of a region. The existence of a good road facilitates access to an area and the community can more easily carry out their activities. This will certainly have a long-term impact on people's lives, one of which is increasing economic growth in the region, one of which can be seen with an increase in Gross Regional Domestic Product (GRDP). The important thing to study more deeply is how the availability of good road facilities in the village is able to contribute to the increase in GRDP.

The Impact

Background: Lack of access to mobility for people with disabilities, particularly in less- resourced settings, continues to be widespread. Despite challenges to wheelchair delivery, the benefits to health, employment, social integration and life satisfaction are apparent.Objectives: Previous studies have explored the impact of receiving a wheelchair on the lives of the users through cross-sectional or short-term longitudinal analysis. The current study was undertaken to evaluate whether previously reported changes were sustained after 30 months of use, and whether results varied between two differing models of a wheelchair.Method: One hundred and ninety-one subjects from Peru, Uganda and Vietnam received one of two models of wheelchair provided by the Free Wheelchair Mission. Using interviews to record survey results, data were collected at the time the wheelchair was received and following 12 and 30 months of use. Variables of overall health, employment, income and travel were explored through non-parametric analysis.Results: There was a significant improvement in overall health and distance travelled after 12 months, but these changes were no longer significant by 30 months (Friedman test for overall change, p = 0.000). Employment status showed a small but significant increase at 12 and 30 months (Cochran’s Q, p = 0.000). Reported income increased slowly, becoming significantly different at 30 months (Friedman test, p = 0.033). There was no association between the model of wheelchair received and the incidence of pressure ulcers, pain or maintenance required. There was higher satisfaction with the GEN_2 wheelchair at 12 months (p = 0.004), but this difference was not apparent by 30 months. Overall wheelchair satisfaction and maintenance levels were favourable.Conclusion: While overall health status, and distance travelled into the community fluctuated over time, receipt of one of two models of a wheelchair in less-resourced settings of the world appears to have a positive sustained impact on employment and income. Further investigations should be carried out to confirm these results and explore the factors responsible for fluctuating variables. This study affirms the importance of long-term follow-up of outcomes associated with wheelchair distribution in less-resourced environments.

PurposeA facemask is used to cover the nose and mouth to protect a wearer's health in daily life. The authors’ long-term goal aimed to ensure more people with different physical characteristics and different attitudes can wear a high performance and comfortable facemask. In the present paper, wearers were surveyed by a questionnaire. Additionally, a prototype improvement pattern with a fit performance was investigated.Design/methodology/approachThe survey of facemask wearers was conducted with local students and international students in Japan. A basic pattern with high fit performance was analyzed using a combination of triangles based on the measured three-dimensional coordinates of the head shape of a Japanese mannequin.FindingsThe aggregated survey data indicated that 85.0% of the Japanese female students, 77.2% of international female students, 70.8% of Japanese male students and 54.3% of international male students were facemask wearers. Wearers had problems related to their masks' thermal, hygroscopic and airflow properties. Japanese nonusers did not wear them due to dislike related to the problems above. International nonusers had no experience of wearing them. It was concerned that these discomfort factors influence fit performance and reduction of wearing effects. Therefore, the authors analyzed a sheet pattern with a high fit performance for a Japanese head mannequin.Originality/valueThese results will contribute in improving hygienic facemasks for people at the global level. The survey results and pattern analysis provide of necessary conditions of development of the mask with comfortable and high fit performance.
