Filtration of Gene Trees From 9,000 Exons, Introns, and UCEs Disentangles Conflicting Phylogenomic Relationships in Tree Frogs (Hylidae)
(Oxford University Press, 2023-05-02)An emerging challenge in interpreting phylogenomic data sets is that concatenation and multi-species coalescent summary species tree approaches may produce conflicting results. Concatenation is problematic because it can ... -
Dynamic Fracture and Crack Arrest Toughness Evaluation of High-Performance Steel Used in Highway Bridges
(MDPI, 2023-04-26)Impact energy tests are an efficient method of verifying adequate toughness of steel prior to it being put into service. Based on a multitude of historical correlations between impact energy and fracture toughness, minimum ... -
Novel 3D Force Sensors for a Cost-Effective 3D Force Plate for Biomechanical Analysis
(MDPI, 2023-03-02)Three-dimensional force plates are important tools for biomechanics discovery and sports performance practice. However, currently, available 3D force plates lack portability and are often cost-prohibitive. To address this, ... -
Methylated histones on mitotic chromosomes promote topoisomerase IIα function for high fidelity chromosome segregation
(Cell Press, 2023-05-19)DNA Topoisomerase IIα (TopoIIα) decatenates sister chromatids, allowing their segregation in mitosis. Without the TopoIIα Strand Passage Reaction (SPR), chromosome bridges and ultra-fine DNA bridges (UFBs) arise in anaphase. ... -
Genetic variation in chromatin state across multiple tissues in Drosophila melanogaster
(Public Library of Science, 2023-05-05)We use ATAC-seq to examine chromatin accessibility for four different tissues in Drosophila melanogaster: adult female brain, ovaries, and both wing and eye-antennal imaginal discs from males. Each tissue is assayed in ... -
Photochemically produced SO2 in the atmosphere of WASP-39b
(Nature Research, 2023-04-26)Photochemistry is a fundamental process of planetary atmospheres that regulates the atmospheric composition and stability1. However, no unambiguous photochemical products have been detected in exoplanet atmospheres so far. ... -
Quality control in resting-state fMRI: the benefits of visual inspection
(Frontiers Media, 2023-05-04)Background: A variety of quality control (QC) approaches are employed in resting-state functional magnetic resonance imaging (rs-fMRI) to determine data quality and ultimately inclusion or exclusion of a fMRI data set in ... -
Asymmetric conformations of cleaved HIV-1 envelope glycoprotein trimers in styrene-maleic acid lipid nanoparticles
(Nature Research, 2023-05-18)During virus entry, the pretriggered human immunodeficiency virus (HIV-1) envelope glycoprotein (Env) trimer initially transits into a default intermediate state (DIS) that remains structurally uncharacterized. Here, we ... -
Dietary overlap and selectivity among mountain steppe river fish in the United States and Mongolia
(Wiley Open Access, 2023-05-21)Lotic systems in mountain regions have historically provided secure habitat for native fish populations because of their relative isolation from human settlement and lack of upstream disturbances. However, rivers of mountain ... -
Cost-effectiveness of Lifestyle Africa: an adaptation of the diabetes prevention programme for delivery by community health workers in urban South Africa
(Taylor and Francis Group, 2023-05-23)Background Lifestyle Africa is an adapted version of the Diabetes Prevention Program designed for delivery by community health workers to socioeconomically disadvantaged populations in low- and middle-income countries ... -
The association of negative mood with automatic and effortful facial expression mimicry
(Frontiers Media, 2023-04-24)The natural process of mimicking the facial expressions of others is well established, as are the deficits in this reflexive behavior for individuals with clinical disorders such as depression. This study examines the ... -
Cell activation-based screening of natively paired human T cell receptor repertoires
(Nature Research, 2023-05-17)Adoptive immune therapies based on the transfer of antigen-specific T cells have been used successfully to treat various cancers and viral infections, but improved techniques are needed to identify optimally protective ... -
Cross-species activation of hydrogen cyanide production by a promiscuous quorum-sensing receptor promotes Chromobacterium subtsugae competition in a dual-species model
(Microbiology Society, 2023-02-15)Many saprophytic bacteria have LuxR-I-type acyl-homoserine lactone (AHL) quorum-sensing systems that may be important for competing with other bacteria in complex soil communities. LuxR AHL receptors specifically interact ... -
Application of the Nicoya OpenSPR to Studies of Biomolecular Binding: A Review of the Literature from 2016 to 2022
(MDPI, 2023-05-17)The Nicoya OpenSPR is a benchtop surface plasmon resonance (SPR) instrument. As with other optical biosensor instruments, it is suitable for the label-free interaction analysis of a diverse set of biomolecules, including ... -
Pharmacological hallmarks of allostery at the M4 muscarinic receptor elucidated through structure and dynamics
(eLife Sciences Publications, 2023-05-20)Allosteric modulation of G protein-coupled receptors (GPCRs) is a major paradigm in drug discovery. Despite decades of research, a molecular-level understanding of the general principles that govern the myriad pharmacological ... -
Optical trapping of sub-millimeter sized particles and microorganisms
(Nature Research, 2023-05-27)While optical tweezers (OT) are mostly used for confining smaller size particles, the counter-propagating (CP) dual-beam traps have been a versatile method for confining both small and larger size particles including ... -
Distributed Tracking Control Design for Leader-Follower Multi-Agent Systems
(University of Kansas, 2022-05-31)Multi-agent systems (MASs) have been widely recognized as a key way to model, analyze, and engineer numerous kinds of complex systems composed of distributed agents. The aim of this dissertation is to study control design ... -
