A novel data source selection algorithm is proposed for ambulatory activity tracking of elderly people. The algorithm introduces the concept of dynamic switching between the data collection modules (a smartwatch and a smartphone) to improve accuracy and battery life using contextual information. We show that by making offloading decisions as a function of activity, the proposed algorithm improves power consumption and accuracy of the previous work by 7 hours and 5% respectively compared to the baseline.

Recent developments in single-cell analysis have revolutionized basic research and have garnered the attention of the forensic domain. Though single-cell analysis is not new to forensics, the ways in which these data can be generated and interpreted are. Modern interpretation strategies report likelihood ratios that rely on a model of the world that is a simplification of it.

Objective: Breast cancer patients often face a significant financial burden, leading to financial toxicity due to the necessity for long-term care, costly treatment, and follow-up measures. The purpose of this study is to systematically review the available qualitative evidence on how breast cancer patients cope with financial toxicity and their unmet need to promote the implementation of effective intervention strategies.

Methods: PubMed, Web of Science, PsycINFO, CINAHL, EMBASE, Scopus, CNKI, Wan Fang Data, and VIP databases were systematically searched for literature related to the study topic.

Polyunsaturated fatty acids (PUFAs) play a crucial role in aiding bacteria to adapt to extreme and stressful environments. While there is a well-established understanding of their production, accrual, and transfer within marine ecosystems, knowledge about terrestrial environments remains limited. Investigation of the intestinal microbiome of earthworms has illuminated the presence of PUFAs presumably of microbial origin, which contrasts with the surrounding soil.
