Demographic model selection using random forests and the site frequency spectrum

open access: yesMolecular Ecology, 2017
AbstractPhylogeographic data sets have grown from tens to thousands of loci in recent years, but extant statistical methods do not take full advantage of these large data sets. For example, approximate Bayesian computation (ABC) is a commonly used method for the explicit comparison of alternate demographic histories, but it is limited by the “curse of ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Allele rank-frequency spectrum. [PDF]

open access: yes, 2018
The rank frequency spectrum of alleles at the 59 loci with ≥ 1000 reads. At each rank i, the black lines designate the quintile boundaries of {fi}, the frequencies of the ith most abundant alleles, across loci. The shades of green show simulated quintile

Terahertz Frequency Domain Response for Insulation State Assessment of Vehicle Cable Terminal Under Electro-Thermal Aging

open access: yesCSEE Journal of Power and Energy Systems
To accurately diagnose the aging condition of the vehicle-mounted high-voltage cable terminals under the combined electro-thermal stress, this paper proposes a terahertz frequency spectrum technology-based method. First, an electro-thermal aging platform

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Site frequency spectrum of derived variants. [PDF]

open access: yes, 2015
(A) The site frequency spectra of 2,983,700 variants classified according to their mutational origin as defined by comparison to the outgroup. Variants are: SW (strong-to-weak; red line; 2,037,148 SNPs in total); WS (weak-to-strong; blue dashed line; 719,

Parameters estimation of stochastic finite fault ground motion simulation method and its application in North China.

open access: yesPLoS ONE
The stochastic finite-fault method based on dynamic corner frequency has been widely applied to simulate high-frequency ground motion of near-fault field. The model input parameters include source term, path term and site condition, many of which exhibit

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Field Testing and Numerical Simulation of the Dynamic Response of Loess Hill Site under High-Speed Train Load

open access: yesShock and Vibration
In this study, the loess hill site of an elevated bridge section in Tongwei-Qin’an of the Baolan high-speed railroad was selected as the research object, and the vibration acceleration of the loess hill site under the elevated bridge was tested in the ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
