Workshop Summary

MET is a relatively new workshop on metamorphic testing for academic researchers and industry practitioners. The first international workshop on MET (MET 2016) was co-located with the 38th International Conference on Software Engineering (ICSE 2016) in Austin TX, USA on May 16, 2016. Since then the workshop has become an annual event. This paper reports on the fourth International Workshop on Metamorphic Testing (MET 2019) held in Montréal, Canada on May 26, 2019, as part of the 41st International Conference on Software Engineering (ICSE 2019). We first outline the aims of the workshop, followed by a discussion of its keynote speech and technical program.

Recent Progress in Storm Surge Forecasting

This report briefly summarizes recent progress in storm surge forecasts, one of topics discussed during the fourth International Workshop on Tropical Cyclone Landfall Process (IWTCLP 4) held during 5-8 December, 2017. In the workshop, improvement of storm surge forecasting system was mainly discussed with relevance to the problem of estimating the impacts of tropical cyclone landfall. To deal with storm surges, accurate TC condition (predictions and forecasts) as input, reasonable storm surge predictions (with forecasting systems), and effective advisories / warnings (i.e. useful information products) are necessary. Therefore, we need to improve storm surge related matters systematically: input, prediction system, and effective information. This report tries to highlight recent progress in the field of storm surges in relation to three key points: improvement in storm surge forecasting models / system, TC conditions as input for storm surge predictions, and informative products for end users.

Recent Advances in Research and Forecasting of Tropical Cyclone Track, Intensity, and Structure at Landfall

This review prepared for the fourth International Workshop on Tropical Cyclone Landfall Processes (IWTCLP-4) summarizes the most recent (2015-2017) theoretical and practical knowledge in the field of tropical cyclone (TC) track, intensity, and structure rapid changes at or near landfall. Although the focus of IWTCLP-IV was on landfall, this summary necessarily embraces the characteristics of storms during their course over the ocean prior to and leading up to landfall. In the past few years, extremely valuable observational datasets have been collected using both aircraft reconnaissance and new geostationary and low-earth orbiting satellites at high temporal and spatial resolution for TC forecasting guidance and research studies. Track deflections for systems near complex topography such as that of Taiwan and La Reunion have been further investigated, and advanced numerical models with high spatial resolution necessary to predict the interaction of the TC circulation with steep island topography have been developed. An analog technique has been designed to meet the need for longer range landfall intensity forecast guidance that will provide more time for emergency preparedness. Probabilistic track and intensity forecasts were also developed to better communicate on forecast uncertainty. Operational practices of several TC forecast centers are described herein and some challenges regarding forecasts and warnings for TCs making landfall are identified. This review concludes with insights from both researchers and forecasters regarding future directions to improve predictions of TC track, intensity, and structure at landfall.

Information Systems in Distributed Environments

This is a report from a one-day fourth international workshop on "Information Systems in Distributed Environments" (ISDE), which was organized in conjunction with the OnTheMove Federated Conferences & Workshops (OTM 2014) October 29-30, 2014, Amantea, Calabria, Italy. The main focus of this event was to provide a venue for the discussion of challenges related to the development, operation, and maintenance of distributed information systems, and their creation in the context of global development projects. Further dissemination of research results will lead to an improvement of distributed information system development and deployment across the globe.

Prevalence of kidney stones and vertebral fractures in primary hyperparathyroidism using imaging technology.

The fourth International Workshop on the Management of Asymptomatic Primary Hyperparathyroidism (PHPT) has recently suggested that skeletal and renal imaging be routinely conducted. So far, no study has systematically assessed this issue. The objective was to evaluate the prevalence of kidney stones (KS) and vertebral fractures (VFs) in a cohort of patients with PHPT utilizing noninvasive imaging technology. This was a prospective study evaluating patients consecutively diagnosed with PHPT in a single center over a 5-year period (2009-2013). The setting was a referral center. There were a total of 140 patients with PHPT (127 women [18 premenopausal and 109 postmenopausal] and 13 men; mean age, 63.2 ± 11 y). Main outcome measures were the prevalence of KS by abdominal ultrasound, osteoporosis by dual-energy x-ray absorptiometry (DXA) (lumbar spine, femoral neck, total hip, and distal 1/3 radius), and VFs by vertebral spine x-ray, with attention to those categorized as symptomatic or asymptomatic. Fifty-five percent of all subjects had KS by ultrasound, 62.9% had osteoporosis by T-score at any site, and 35.1% had VFs by x-ray. There was no difference in the incidence of VFs and densitometric osteoporosis between symptomatic and asymptomatic patients (VFs, 34.4 vs 34.7%; osteoporosis by DXA, 59.4 vs 65.8%), whereas more KS were detected in symptomatic (78%) than asymptomatic (35.5%). Twenty-two percent of patients classified as asymptomatic at baseline without osteoporosis by DXA were found to have KS and/or VFs. Nephrolithiasis and VFs are common in asymptomatic subjects with PHPT. The results provide evidence in support of recent recommendations that a more proactive approach be taken to detect silent bone and stone disease in asymptomatic PHPT.

Fourth International Workshop on Space Radiation Research (IWSRR)

The goal of understanding the planets and stars provided a unifying perspective to international scientists such as Galileo Galilei, Johannes Kepler and Michail V. Lomonosov who studied the nature of space leading to advances on Earth. Astronauts and cosmonauts from many diverse nations now routinely venture into space, often on joint missions, and share a common perspective of the Earth and Heavens from their unique vantage point. However, the length and destination, such as the moon or Mars, of space missions are currently constrained by the potentially detrimental health risks from space radiation. The reduction of uncertainties in risk projection models for cancer and other late effects, and the development of effective mitigation measures to protect against galactic cosmic rays and solar energetic particles are active areas of scientific research [1]. The fourth International Workshop on Space Radiation Research (IWSRR) held June 5–9, 2006, which included the 17th Annual NASA Space Radiation Health Investigators Meeting, was a unique opportunity to bring leading researchers from all space bearing nations together to create a unifying perspective for realizing solutions to the problem of space radiation. Space radiation research is by its nature an inter-disciplinary science, spanning several areas of biology, physics, and engineering [1]. The fourth IWSRR built on the success of previous meetings held in the cities of Arona in Italy [2], Nara in Japan [3], and Port Jefferson in the United States [4]. However the theme for the meeting, ‘‘From Stars to Stars’’ explored new boundaries since for the first time the meeting was held in two great cities, Moscow and St. Petersburg with a starlight journey by train connecting the cities at the half-way point of the meeting. The life of Michail V. Lomonosov (B. 1711, D. 1765) serves as a fitting symbol for the meeting. Known for his observations of the atmosphere of Venus, he was a member of the faculty at the St. Petersburg Imperial Academy of Sciences, but later founded Moscow State University, and made inter-disciplinary contributions to several areas of science and literature [5]. This special issue of the journal ‘‘Radiation and Environmental Biophysics’’ contains 20 peer-reviewed papers contributed by leading space radiation researcher’s worldwide attending the fourth IWSRR. Manuscripts cover a broad range of topics ranging from radiation environments and transport in shielding and planetary surfaces to new results in understanding the biological effects of protons and high-charge and energy (HZE) nuclei on the risk of cancer, and degenerative diseases such as central nervous system effects, heart disease, and cataracts. The issue provides a snapshot of the state-of-the-art of the research in this field, demonstrating both the important results gathered in the past few years with experiments at accelerators, and the need for more research to quantify the risk and develop countermeasures.

Solving the swath segment selection problem through Lagrangean relaxation

The swath segment selection problem ( SSSP) is an NP -hard combinatorial optimization problem arising in the context of planning and scheduling satellite operations. It was defined by Muraoka et al. [ASTER observation scheduling algorithm. In: Proceedings of SpaceOps 1998, Tokyo, Japan, 1998] and Knight and Smith [Optimal nadir observation scheduling. In: Proceedings of the fourth international workshop on planning and scheduling for space (IWPSS 2004), Darmstadt, Germany, 2004], who respectively proposed a greedy algorithm, named ASTER, and a branch-and-bound algorithm based on a network flow relaxation. Here we tackle the problem with more advanced mathematical programming tools: using a Lagrangean relaxation, coupled with a Lagrangean heuristic and subgradient optimization, we solve in one hour instances with up to 500 000 swath segments within 0.4 % of the optimum. The algorithm also proves experimentally superior to commercial MIP solvers in computing heuristic solutions.

A report on the fourth international workshop on environmental applications of machine learning (EAML 2004)

The Fourth International Workshop on Environmental Applications of Machine Learning (EAML) was organized in Bled, Slovenia, during the week of September 27 – October 1, 2004, jointly with the Fourth European Conference on Ecological Modelling (ECEM). The aim of these events was to bring together researchers from the areas of ecology, ecological modelling and environmental sciences, on one hand, and the areas of data analysis, data mining and machine learning, on the other. In many respects, they were treated as a single event, namely ECEM/EAML 2004. As environmental concerns grow and information technology develops, more and more data on the different aspects (physical, chemical, biological, ecological) of the environment are gathered. There is an increasing need to analyse the collected environmental data for different purposes, which include the support for environmental management decisions. Machine learning methods can be used to discover knowledge in environmental data, as well as construct ecological models in an automated fashion, thus providing support for environmental management. The International Workshop on Environmental Applications of Machine Learning provided a forum for presenting recent advances in applying machine learning and data mining techniques for the analysis of environmental data. EAML 2004 was the fourth workshop on the topic, with previous workshops mainly attracting researchers in ecological modeling interested in the use of machine learning. The ECEM/EAML 2004 conference brought together participants from both communities, including many prominent figures, such as the founders/first editors of the journals of Ecological Modelling and Machine Learning. The scientific program of ECEM/EAML 2004 consisted of invited lectures as well as oral and poster presentations of accepted contributions. The conference brought together two separate communities which have overlapping research topics. Both events have had separate advisory committees and invited speakers. However, the program chairs and organizing committee as well as the program committee and review process were joint for both events. Also, a single registration fee allowed access to both events. In addition to the scientific program, each day was concluded with a social event which facilitated the interaction and communication between the two communities. Each of ECEM and EAML lasted for three days (EAML September 27-29, ECEM September 29 to October 1). Wednesday September 29 was a joint/overlap day, with a joint invited speaker, technical sessions of interest to both communities and a joint poster session. A total of 110 abstracts were submitted until March 20. Each submitted abstract was sent to three members of the program committee for review. The program committee members themselves did the majority of reviews, assisted by some additional reviewers appointed by the committee members. Classification of accepted presentations for oral or poster sessions was based on the reviewers’ evaluation of their quality and generality of interest. Revised versions of accepted abstracts were published in two separate proceedings, one for ECEM 2004 (ISBN:961-6303-60-0) and another for EAML 2004 (ISBN: 961-6303-59-7). Both proceedings are available on-line from the website of ECEM/EAML. Of the 110 submissions, 90 were accepted. Of these, 29 went to EAML and 61 to ECEM. Authors of accepted abstracts (for both oral and poster presentation) were invited to submit full versions of their papers by June 20. About 60 full papers have been already submitted, and they are currently being reviewed by members of the program committee and additional reviewers. The accepted papers will be published in two special issues of the journal Ecological Modelling (one for ECEM 2004, one for EAML 2004). At ECEM/EAML, opening addresses were given by distinguished guests. These included Zoran Stancic (State secretary, Slovenian Ministry of Education, Science and Sport) and Nada Lavrac (Head of the Department of Knowledge Technologies, Jožef Stefan Institute, Ljubljana), who spoke at the opening of EAML 2004 on September 27. Tarzan Legovic (President of European Chapter of ISEM, Rudjer Boskovic Institute, Zagreb, Croatia) spoke at the opening of ECEM 2004 on September 29. The program of EAML 2004 included three invited talks, given by Joseph C. Coughlan (NASA Ames, USA), Cesare Furlanello (ITC-irst, Trento, Italy), and Jacqueline McGlade (European Environment Agency), as well as 22 oral and 7 poster presentations of accepted contributions.

Mysteries, Puzzles and Paradoxes in Quantum Mechanics

The fourth International Workshop on `Mysteries, Puzzles and Paradoxes in Quantum Mechanics' was held from 27 August to 1 September 2001, at the Palazzo Feltrinelli in Gargnano, Italy, as were the first three, on the shore of Lake Garda. It continued the tradition of the previous workshops in seeking a deeper understanding of the foundations of quantum mechanics. After more than 75 years, this field of investigation is still active and able to stimulate both intense discussions and interesting physics research, involving many physicists from quite different fields. For that reason, this special issue of Journal of Optics B: Quantum and Semiclassical Optics confronts many different aspects of quantum mechanics, as afforded from many different points of view.

Report on the ACM fourth international workshop on data warehousing and OLAP (DOLAP 2001)

The Fourth Annual ACM International Workshop on Data Warehousing and Online Analytical Processing (DOLAP 2001) was held in Atlanta, GA, USA, in November 2001, in conjunction with the Tenth International Conference on Information and Knowledge Management (CIKM 2001). Although this was only the fourth annual meeting, DOLAP has already become an important and broadly accepted forum for researchers and practitioners to share their findings in theoretical foundations, current methodologies, practical experiences, and new research directions in the areas of data warehousing and online analytical processing (OLAP). Despite the fact that conference attendance has been down since the horrific events of September 11, DOLAP 2001 attracted researchers from Europe, Asia and the Americas.The DOLAP 2001 program, which occupied a full day immediately following CIKM 2001, included a keynote talk, technical presentations, and a final discussion involving all workshop participants. As in previous years, the quality of the submitted papers was high and the program committee had a difficult time deciding which of the 31 submissions from 16 different countries should be accepted for presentation. The submitted research papers covered the state-of-the-art in data warehousing and related fields including data warehouse architecture, design and evolution, multi-dimensional modeling, query optimization, indexing, view materialization and maintenance, data warehouse quality, XML- and object-based warehouses, and data warehousing and the Web. In addition, the committee received a number of industrial submissions describing ongoing data warehousing projects and novel applications for warehouses. After careful review, 12 research and industrial papers were selected for presentation at DOLAP 2001. The proceedings are published by ACM Press, and are also available online at www.informatik.uni-trier.de/~ley/db/conf/dolap/dolap2001.html.In addition, the authors of the three highest-ranked papers have been invited to submit an updated, more detailed version to the Special Issue on Advances in Data Warehousing of the Data and Knowledge Engineering Journal to be published in early 2003.
