Konferensbidrag (refereegranskat)abstract
- The Visual Object Tracking Segmentation VOTS2023 challenge is the eleventh annual tracker benchmarking activity of the VOT initiative. This challenge is the first to merge short-term and long-term as well as single-target and multiple-target tracking with segmentation masks as the only target location specification. A new dataset was created; the ground truth has been withheld to prevent overfitting. New performance measures and evaluation protocols have been created along with a new toolkit and an evaluation server. Results of the presented 47 trackers indicate that modern tracking frameworks are well-suited to deal with convergence of short-term and long-term tracking and that multiple and single target tracking can be considered a single problem. A leaderboard, with participating trackers details, the source code, the datasets, and the evaluation kit are publicly available at the challenge website1

Forskningsöversikt (refereegranskat)abstract
- Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative efforts, scientific breakthroughs can be made sooner and capitalized for the betterment of humanity.

Tidskriftsartikel (refereegranskat)abstract
- The COVID-19 pandemic has affected all domains of human life, including the economic and social fabric of societies. One of the central strategies for managing public health throughout the pandemic has been through persuasive messaging and collective behaviour change. To help scholars better understand the social and moral psychology behind public health behaviour, we present a dataset comprising of 51,404 individuals from 69 countries. This dataset was collected for the International Collaboration on Social & Moral Psychology of COVID-19 project (ICSMP COVID-19). This social science survey invited participants around the world to complete a series of moral and psychological measures and public health attitudes about COVID-19 during an early phase of the COVID-19 pandemic (between April and June 2020). The survey included seven broad categories of questions: COVID-19 beliefs and compliance behaviours; identity and social attitudes; ideology; health and well-being; moral beliefs and motivation; personality traits; and demographic variables. We report both raw and cleaned data, along with all survey materials, data visualisations, and psychometric evaluations of key variables.

Compensating Effects Between Climate and Underlying Characteristics on Watershed Water Loss
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Identifying climate impacts on watershed water loss (evapotranspiration) generally involves the interactions with land surface change (e.g., vegetation dynamics and anthropogenic disturbances). Here, we seek to understand the compensating effects of climate and underlying characteristics on watershed evapotranspiration. In this regard, an analytical solution was derived by using a simple water-energy partitioning framework for separating the individual contributions of climate and underlying characteristics to changes in watershed actual evapotranspiration between 1930-1970 and 1971-2008 over global 87 basins. We found that for the basins with larger increases in the total evapotranspiration, a positive underlying characteristic-related contribution is dominant, rather than the climate-related contribution. Tradeoffs (i.e., the compensating effects) between the contributions of climate and underlying characteristics to evaporative water loss were also identified in a few basins where there were relatively large changes in the underlying characteristic-related evapotranspiration but only a slight change in the total evapotranspiration. This suggests that the climate contribution in evapotranspiration may offset the effect of underlying characteristic-related changes over these basins, associated with stronger hydrological resilience under the double impacts of both climate and underlying factors. The results also indicate that the underlying characteristics exert greater contributions to the changes in the total evapotranspiration rather than the climate variation, and the underlying characteristic-related evapotranspiration variations are closely related to the changes in reservoirs and land-use types of the basins. The presented findings may provide an insightful understanding of interactions among climate, water, and underlying characteristics over global basins.
