Unraveling the Growth Dynamics of Rutile SnGeO Using Theory and Experiment.

Nano Lett

December 2024

Department of Chemical Engineering and Materials Science, University of Minnesota-Twin Cities, Minneapolis, Minnesota 55455, United States.

Rutile GeO and related materials are attracting interest due to their ultrawide band gaps and potential for ambipolar doping in high-power electronic applications. This study examines the growth of rutile SnGeO films through oxygen-plasma-assisted hybrid molecular beam epitaxy (hMBE). The film composition and thickness are evaluated across a range of growth conditions, with the outcomes rationalized by using density functional theory calculations.

Pooled nanoparticle screening using a chemical barcoding approach.

Angew Chem Int Ed Engl

December 2024

University of Minnesota Twin Cities College of Science and Engineering, Chemical Engineering and Materials Science, 421 Washington Ave SE, 55455, Minneapolis, UNITED STATES OF AMERICA.

We report the development of a small molecule-based barcoding platform for pooled screening of nanoparticle delivery. Using aryl halide-based tags (halocodes), we achieve high-sensitivity detection via gas chromatography coupled with mass spectrometry or electron capture. This enables barcoding and tracking of nanoparticles with minimal halocode concentrations and without altering their physicochemical properties.

Recent studies on graph representation learning in brain tumor learning tasks have garnered significant interest by encoding and learning inherent relationships among the geometric features of tumors. There are serious class imbalance problems that occur on brain tumor MRI datasets. Impressive deep learning models like CNN- and Transformer-based can easily address this problem through their complex model architectures with large parameters.

Expression-Dependent Tumor Pretargeting via Engineered Avidity.

Mol Pharm

December 2024

Department of Biomedical Engineering, University of Minnesota-Twin Cities, Minneapolis, Minnesota 55455, United States.

Selective delivery of therapeutic modalities to tumor cells via binding of tumor-selective cell-surface biomarkers has empowered substantial advances in cancer treatment. Yet, tumor cells generally lack a truly specific biomarker that is present in high density on tumor tissue while being completely absent from healthy tissue. Rather, low but nonzero expression in healthy tissues results in on-target, off-tumor activity with detrimental side effects that constrain the therapeutic window or prevent use altogether.

Recent extensive studies on the genomic and molecular profiles of acute myeloid leukemia (AML) have expanded the treatment options, including, a range of compounds represented by fms-like tyrosine kinase 3 and isocitrate dehydrogenase 1/2 inhibitors. However, despite this progress, further treatments for AML are still required. Adenosine deaminase acting on RNA 1 (ADAR1) has been shown to play an important oncogenic role in many cancers, but its involvement in AML progression remains underexplored.

The Hybrid History of Zebrafish.

G3 (Bethesda)

December 2024

Institute of Neuroscience, University of Oregon, Eugene, OR 97403, USA.

Since the description of zebrafish (Danio rerio) in 1822, the identity of its closest living relative has been unclear. To address this problem, we sequenced the exomes of ten species in genus Danio, using the closely related Devario aequipinnatus as outgroup, to infer relationships across the 25 chromosomes of the zebrafish genome. The majority of relationships within Danio were remarkably consistent across all chromosomes.

Interfacial charge transfer and its impact on transport properties of LaNiO/LaFeO superlattices.

Sci Adv

December 2024

Physical and Computational Sciences Directorate, Pacific Northwest National Laboratory, Richland, WA 99354, USA.

Charge transfer or redistribution at oxide heterointerfaces is a critical phenomenon, often leading to remarkable properties such as two-dimensional electron gas and interfacial ferromagnetism. Despite studies on LaNiO/LaFeO superlattices and heterostructures, the direction and magnitude of the charge transfer remain debated, with some suggesting no charge transfer due to the high stability of Fe (3d). Here, we synthesized a series of epitaxial LaNiO/LaFeO superlattices and demonstrated partial (up to ~0.

This conceptual analysis focuses on opportunities to advance research and current hypotheses of perceptual development by examining what is presently known and unknown about perceptual specialization in a Multiracial context during the first year of life. The impact of being raised in a Multiracial family or community is discussed to further characterize the development of perceptual expertise for faces and languages. Historical and present-day challenges faced by researchers in defining what race is, identifying Multiracial individuals or contexts, and how to study perceptual and cognitive processes in this population are discussed.

Purpose: The current study addresses a gap in the literature regarding syntactic development of adolescent boys with fragile X syndrome (FXS) and Down syndrome (DS). Specifically, we ask whether syntactic skills plateau or continue to change during adolescence for these groups and whether the profile of syntactic change differs between boys with FXS and those with DS.

Method: Participants were 38 boys with FXS (with and without autism) and 20 boys with DS between the ages of 10 and 16 years, as well as 33 boys who were neurotypical between the ages of 3 and 8 years at study entry.

Pubertal trends, wherein adolescents today are experiencing puberty earlier than prior generations, have coincided with the expansion of the criminal legal system, which is disproportionately impacting communities of color. However, whether pubertal development and criminal legal system exposure among adolescents are inter-related is unknown. We tested whether family members' criminal legal system exposure predicted adolescents' pubertal development, whether family strain explained the relation between criminal legal system exposure and pubertal development, and whether race/ethnicity moderated our results.

Prenylation consists of the modification of proteins with either farnesyl diphosphate (FPP) or geranylgeranyl diphosphate (GGPP) at a cysteine near the C-terminus of target proteins to generate thioether-linked lipidated proteins. In recent work, metabolic labeling with alkyne-containing isoprenoid analogues including C15AlkOPP has been used to identify prenylated proteins and track their levels in different diseases. Here, a systematic study of the impact of isoprenoid length on proteins labeled with these probes was performed.

Parental incarceration touches the lives of millions of school-aged children and youth. School psychologists are positioned to support students who have experienced the incarceration of a loved one and to consult with school team members to boost students' long-term outcomes. This scoping review aimed to assess the scope and extent of parental incarceration's presence in the peer-reviewed and practitioner-oriented literature of school psychology, as well as to compare school psychology to the related disciplines of school counseling and special education.

Article Synopsis
  • Horses were studied to see how using hay nets affects their health, specifically looking at skeletal issues and pain thresholds.
  • In a year-long study, 13 horses were divided into two groups, one with hay nets and the other without, and changes in their health metrics were evaluated.
  • Results showed that while horses with hay nets had slightly more cervical subluxations, they also exhibited better cervical range of motion, indicating that using hay nets may have minimal impacts on horse health overall.

Search for CP-Violating Neutrino Nonstandard Interactions with the NOvA Experiment.

Phys Rev Lett

November 2024

Fermi National Accelerator Laboratory, Batavia, Illinois 60510, USA.

This Letter reports a search for charge-parity (CP) symmetry violating nonstandard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from ν_{μ}(ν[over ¯]_{μ})→ν_{μ}(ν[over ¯]_{μ}) and ν_{μ}(ν[over ¯]_{μ})→ν_{e}(ν[over ¯]_{e}) oscillation channels are used to measure the effect of the NSI parameters ϵ_{eμ} and ϵ_{eτ}. With 90% CL the magnitudes of the NSI couplings are constrained to be |ϵ_{eμ}|≲0.
