Structure Tensor Total Variation [PDF]
SIAM Journal on Imaging Sciences, 2015 Summary: We introduce a novel generic energy functional that we employ to solve inverse imaging problems within a variational framework. The proposed regularization family, termed as structure tensor total variation (STV), penalizes the eigenvalues of the structure tensor and is suitable for both grayscale and vector-valued images.

Structural variations in papaya genomes [PDF]
BMC Genomics, 2021 Abstract Background Structural variations (SVs) are a type of mutations that have not been widely detected in plant genomes and studies in animals have shown their role in the process of domestication. An in-depth study of SVs will help us to further understand the impact of SVs on the phenotype and environmental ...

Deep Variational and Structural Hashing
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020 In this paper, we propose a deep variational and structural hashing (DVStH) method to learn compact binary codes for multimedia retrieval. Unlike most existing deep hashing methods which use a series of convolution and fully-connected layers to learn binary features, we develop a probabilistic framework to infer latent feature representation inside the

Divergent drivers of leaf trait variation within species, among species, and among functional groups. [PDF]
, 2018 Understanding variation in leaf functional traits-including rates of photosynthesis and respiration and concentrations of nitrogen and phosphorus-is a fundamental challenge in plant ecophysiology. When expressed per unit leaf area, these traits typically

Niche Specialization and Functional Overlap of Bamboo Leaf and Root Microbiota
Frontiers in Microbiology, 2020 Leaves and roots harbor taxonomically diverse bacterial assemblages which enhance plant growth and performance by increasing nutrient supply and resistance to stress. An extensive investigation of bacterial diversity and composition between leaf and root

Evaluation of Germline Structural Variant Calling Methods for Nanopore Sequencing Data
Frontiers in Genetics, 2021 Structural variants (SVs) are genomic rearrangements that involve at least 50 nucleotides and are known to have a serious impact on human health. While prior short-read sequencing technologies have often proved inadequate for a comprehensive assessment ...

Understanding genome structural variations
Oncotarget, 2015 Genome structural variations (SVs) in the human genome are defined as DNA sequence polymorphisms of at least a few dozen or few hundred bases in length and include deletions, duplications, inversions, translocation, retroelement insertions, and more complex rearrangements that could be thought of as consisting of multiple fragments from the just listed

Identifying Structural Variation in Haploid Microbial Genomes from Short-Read Resequencing Data Using Breseq [PDF]
, 2014 Mutations that alter chromosomal structure play critical roles in evolution and disease, including in the origin of new lifestyles and pathogenic traits in microbes.
