Haplotype‐resolved genome and pan‐genome graphs reveal the impacts of structural variation on functional genome and feather colors in chickens

open access: yesiMetaOmics, EarlyView.
This study built a Wenchang chicken haplotype genome and integrated it with 29 others to create a chicken pangenome atlas. Analysis of 354 chickens revealed 185,205 structural variations (SVs), with one‐third derived from homology‐based and transposable elements.

De Novo Whole Genome Assemblies of Unusual Case‐Making Caddisflies (Trichoptera) Highlight Genomic Convergence in the Composition of the Major Silk Gene (h‐fibroin)

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
The major silk gene, h‐fibroin, was annotated in high‐quality genomes of two unusual case‐making Trichoptera. H‐Fibroin of Limnocentropus insolitus shows a similar amino acid composition to other case‐making species, while the amino acid composition of h‐fibroin of Phryganopsyche brunnea resembles that of retreat‐making species.

Random sequential adsorption of partially oriented linear $k$-mers on square lattice

open access: yes, 2011
Jamming phenomena on a square lattice are investigated for two different models of anisotropic random sequential adsorption (RSA) of linear $k$-mers (particles occupying $k$ adjacent adsorption sites along a line).

Mass spectrometry of dendrimers

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Mass spectrometry (MS) has become an essential technique to characterize dendrimers as it proved efficient at tackling analytical challenges raised by their peculiar onion‐like structure. Owing to their chemical diversity, this review covers benefits of MS methods as a function of dendrimer classes, discussing advantages and limitations of ...

Degradation strategies for structural characterization of insoluble synthetic polymers by mass spectrometry

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract With the advent of soft ionization techniques such as electrospray (ESI) and matrix‐assisted laser desorption/ionization (MALDI) to produce intact gas‐phase ions from nonvolatile macromolecules, mass spectrometry has become an essential technique in the field of polymeric materials.

iDOM: Statistical analysis of dissolved organic matter characterized by high‐resolution mass spectrometry

open access: yesmLife, EarlyView.
Abstract Dissolved organic matter (DOM) contains thousands of molecules and is key for biogeochemical cycles in aquatic and terrestrial ecosystems by interacting with microbes. Over the last decade, the study of DOM has been advanced and accelerated with the developments of instrumental and statistical approaches.

The Antiviral Activity of Polyphenols

open access: yesMolecular Nutrition &Food Research, EarlyView.
Polyphenols demonstrate remarkable antiviral properties by effectively disrupting multiple biochemical processes essential for viral replication. ABSTRACT Polyphenols are secondary metabolites produced by a large variety of plants. These compounds that comprise the class of phenolic acids, stilbenes, lignans, coumarins, flavonoids, and tannins have a ...

Computing Phylo-k-mers

open access: yes, 2022
Phylogenetically informed k-mers, or phylo-k-mers for short, are k-mers that are predicted to appear within a given genomic region at predefined locations of a fixed phylogeny.
