Structural variations (SVs) are commonly found in cancer genomes. They can cause gene amplification, deletion and fusion, among other functional consequences. With an average read length of hundreds of kilobases, nano-channel-based optical DNA mapping is powerful in detecting large SVs. However, existing SV calling methods are not tailored for cancer samples, which have special properties such as mixed cell types and sub-clones. Here we propose the Cancer Optical Mapping for detecting Structural Variations (COMSV) method that is specifically designed for cancer samples. It shows high sensitivity and specificity in benchmark comparisons. Applying to cancer cell lines and patient samples, COMSV identifies hundreds of novel SVs per sample.

Varietal mixtures are a promising agro-ecological approach to stabilizing yields by reducing diseases. The effects of mixtures stem from modifications of epidemiological processes and underestimated plant-plant interactions, which could explain some of the paradoxical observations made in the field. However, the role of plant-plant interactions in modifying bread wheat and durum wheat susceptibility to Septoria tritici blotch remains to be elucidated.

Citizen science engages volunteers to contribute data to scientific projects, often through visual annotation tasks. Hearing based activities are rare and less well understood. Having high quality annotations of performed music structures is essential for reliable algorithmic analysis of recorded music with applications ranging from music information retrieval to music therapy.

Microfibers are pollutants of increasing concern, as they accumulate in aquatic environments and pose risks to living organisms. Once released, they undergo degradation processes that reduce their size and enhance their ability to interact with biological systems. Among these processes, photodegradation is a key driver, leading to fiber fragmentation and structural shrinkage.

Population genetics plays a critical role in creating policies for managing fisheries, conservation, and development of aquaculture. The golden snapper, Lutjanus johnii (Bloch, 1792), is a highly commercial and aquaculture important snapper species. This study used mitochondrial markers D-loop (151 specimens) and Cytochrome b (Cyt-b, 120 specimens) from 10 populations, including populations from the east South China Sea, the west South China Sea and the Strait of Malacca to investigate the genetic diversity, population connectivity, and historical demography of L.

The anterior commissure (AC) has an anterior and posterior limb. Despite comprehensive information about the posterior limb, there is limited and conflicting information about the anterior limb in the literature. We aimed to show the anatomical relationships of the AC with neighboring structures by using white matter microdissection and magnetic resonance (MR) tractography, primarily on the anterior limb of the AC.
