Computing k-mers in Graphs

We initiate the study of computational problems on $k$-mers (strings of length $k$) in labeled graphs. As a starting point, we consider the problem of counting the number of distinct $k$-mers found on the walks of a graph. We establish that this is #P-hard, even on connected deterministic DAGs.

Interfacial Energy and Composition Controlled Self‐Stratification in Polyurethane Coatings

Macromolecular Materials and Engineering, EarlyView.
This study elucidates self‐stratification in polyurethane coatings driven by interfacial energies and composition‐dependent phase separation. Using XPS, SIMS, and Raman analyses, we reveal rapid formation of hydrophobic and hydrophilic layers and substrate‐dependent interfacial structures.

Identification of genetic relationships and subspecies signatures in Xylella fastidiosa

BMC Genomics, 2019
Background The phytopathogenic bacterium Xylella fastidiosa was thought to be restricted to the Americas where it infects and kills numerous hosts. Its detection worldwide has been blooming since 2013 in Europe and Asia. Genetically diverse, this species

Human Cyclophilins—An Emerging Class of Drug Targets

Medicinal Research Reviews, EarlyView.
ABSTRACT Cyclophilins are a family of enzymes with peptidyl‐prolyl isomerase activity found in all cells of all organisms. To date, 17 cyclophilin isoforms have been identified in the human body, participating in diverse biological processes. Consequently, cyclophilins have emerged as promising targets for drug development to address a wide array of ...

Mitigating Health Disparities Through Empathetic Policymaking During Times of Crisis

Public Administration and Development, EarlyView.
ABSTRACT The COVID‐19 pandemic greatly exacerbated the existing disparities and inequities in health and healthcare among historically marginalized populations. Today, these impacts still echo. These persistent structured inequities erode the public's trust in government, lead to failure in public policies, and result in worse health consequences ...

The impact of COVID‐19 on public perceptions of wild meat in Central Africa

People and Nature, EarlyView.
Abstract Wild meat is a significant source of food and income generation in Central Africa. However, there is little knowledge of how the assumed link between COVID‐19 and wild meat consumption has been discussed by the media and received by the public. In this study, we conducted media content analysis of 264 articles published in 2019–2020 related to

Indexing k-mers in Linear-space for Quality Value Compression

Bioinformatics, 2019
Many bioinformatics tools heavily rely on k-mer dictionaries to describe the composition of sequences and allow for faster reference-free algorithms or look-ups.

Structural Analysis and Inhibitor Modeling of Bacterioferritin From Brucella abortus

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Iron homeostasis in various pathogenic bacteria is regulated by bacterioferritins (Bfr) which function to store Fe3+ and release Fe2+ as needed for metabolic processes. The Bfr structure consists of 18 kDa subunits in which dimer pairs bind a heme molecule and are assembled into a highly symmetrical 24‐meric spherical structure with an ...

K-mer-based host screening v1

, 2016
K-mer-based approaches to determining sequence similiarity can befaster than traditional use of BLAST. This application usesJellyfishto index host FASTA files, then uses the mode value (default 2)of the number of matching k-mers (default k=20) from the input sequenceto determine whether the sequence is similar enough to the host sequence to be rejected.
