Acetaldehyde oxidation at elevated pressure (open access)

Acetaldehyde oxidation at elevated pressure

A detailed chemical kinetic model for oxidation of CH3CHO at intermediate to high temperature and elevated pressure has been developed and evaluated by comparing predictions to novel high-pressure flow reactor experiments as well as shock tube ignition delay measurements and jet-stirred reactor data from literature. The flow reactor experiments were conducted with a slightly lean CH3CHO/O2 mixture highly diluted in N2 at 600–900 K and pressures of 25 and 100 bar. This is the accepted manuscript version of the published article.

Action unit classification for facial expression recognition using active learning and SVM (open access)

Action unit classification for facial expression recognition using active learning and SVM

Article utilizing active learning and support vector machine (SVM) algorithms to classify facial action units (AU) for human facial expression recognition. Experimental results show that the proposed algorithm can effectively suppress correlated noise and achieve higher recognition rates than principal component analysis and a human observer on seven different facial expressions.

Anti-racist Pedagogy in Art and Museums captions transcript

Anti-racist Pedagogy in Art and Museums

Video recording featuring guest panelists, Stephanie A. Johnson-Cunningham, and Kelli Morgan, Ph.D., this third installment of the 2044 series frames Afrofuturism and futurist thinking in museum practice to examine the roles museums play in maintaining and recreating anti-blackness and white supremacy. Panelists discuss how museum educators and curators can practice anti-racist pedagogy and thinking. Racist and colonial practices of museums need greater racial equity and recognition. Through the use of visual imagery, Afrofuturism as a framework may be a viable strategy for community building, imagination, and expression. Recognizing that museums are rooted in white colonial narratives that have been and continue to be oppressive to Black and people of color, museums can amplify Black experiences and narratives while pointing out the need for systemic change in the sector. From the periphery of colonial violence and commodification to the centrality of visibility and recognition, museum education can provide opportunities to “analyze how racism shapes how we view, discuss, create, and engage multiple audiences within the museums.”

Arabidopsis thaliana EARLY RESPONSIVE TO DEHYDRATION 7 Localizes to Lipid Droplets via Its Senescence Domain (open access)

Arabidopsis thaliana EARLY RESPONSIVE TO DEHYDRATION 7 Localizes to Lipid Droplets via Its Senescence Domain

This article includes a proteomics analysis of Lipid Droplets (LDs) isolated from drought-stressed Arabidopsis leaves and identifying EARLY RESPONSIVE TO DEHYDRATION 7 (ERD7) as a putative LD protein. Observations provide new insight to ERD7 and the SD-containing family of proteins in plants and suggest that ERD7 may be involved in functional aspects of plant stress response that also include localization to the LD surface.

Branching of Titanium Nanorods

This article reports that Ti nanorod branching occurs at a low homologous temperature of 0.28 based on physical vapor deposition and characterizations using electron microscopy and X-ray diffraction. The insight into conditions for branching, together with the determination of the morphology and crystal orientation of the branches, lay the foundation for further studies of branching mechanisms and driving force.

Childhood Asthma and Smoking: Moderating Effect of Preterm Status and Birth Weight

Article exploring the association between second-hand smoke exposure, asthma, and asthma severity in children ages 6-17 as well as the effect of birth weight and prematurity (BWP) on parental smoking and asthma. Results indicate that focused asthma interventions in children should inquire about BWP status as well as parental smoking and household smoke exposure to reduce asthma morbidity and mortality.

CRISPR/Cas9-Induced fad2 and rod1 Mutations Stacked With fae1 Confer High Oleic Acid Seed Oil in Pennycress (Thlaspi arvense L.) (open access)

CRISPR/Cas9-Induced fad2 and rod1 Mutations Stacked With fae1 Confer High Oleic Acid Seed Oil in Pennycress (Thlaspi arvense L.)

Article utilizing Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology to produce knockout mutations in the FATTY ACID DESATURASE2 (FAD2) and REDUCED OLEATE DESATURATION1 (ROD1) genes to increase oleic acid content in Pennycress (Thlaspi arvense L.). Results suggest that combinatorial knockout of ROD1 and FAE1 may be a viable route to commercially increase oleic acid content in pennycress seed oil whereas mutations in FAD2 will likely require at least partial function to avoid fitness trade-offs.

A cytoskeletal function for PBRM1 reading methylated microtubules (open access)

A cytoskeletal function for PBRM1 reading methylated microtubules

This article shows that that the coordinated read-write activity of the epigenetic machinery extends to the cytoskeleton, with PBRM1 in the PBAF chromatin remodeling complex reading microtubule methyl marks written by the SETD2 histone methyltransferase. This article opens a previously unknown window into how chromatin remodeler defects can drive disease via both epigenetic and cytoskeletal dysfunction.

Discovery of higher-order topological insulators using the spin Hall conductivity as a topology signature

This article shows a connection between spin Hall effect and HOTIs using a combination of ab initio calculations and tight-binding modeling. The model demonstrates how a non-zero bulk midgap spin Hall conductivity (SHC) emerges within the HOTI phase. This work guides novel experimental and theoretical advances towards higher-order topological insulator realization and applications.
