Sedimentary nitrogen isotopic ratios are used as a proxy for ancient biogeochemical cycles on Earth's surface. It is generally accepted that sediment hole tops record primary signatures because organic nitrogen (ON) is predominant in this part of the hole. In contrast to such early to middle diagenetic stages, it is well known that heavier nitrogen isotope 15N tends to enrich in sedimentary rocks during later diagenetic and metamorphic stages. However, there are some critical gaps in our understanding of nitrogen isotopic alteration associated with abiotic processes during early-middle diagenesis. In this study, we examined the isotope ratios of ammonium nitrogen …

Inquiries into properties of brain structure and function have progressed due to developments in magnetic resonance imaging (MRI). To sustain progress in investigating and quantifying neuroanatomical details in vivo, the reliability and validity of brain measurements are paramount. Quality control (QC) is a set of procedures for mitigating errors and ensuring the validity and reliability of brain measurements. Despite its importance, there is little guidance on best QC practices and reporting procedures. The study of hippocampal subfields in vivo is a critical case for QC because of their small size, inter-dependent boundary definitions, and common artifacts in the MRI data …

Antibiofilm Activity Of Pdms/Tio2 Against Candida Glabrata Through Inhibited Hydrophobic Recovery, Khoi Nguyen Nguyen, Leena Sao, Kevin Kyllo, Danitza Hernandez, Samantha Salomon, Kalp Shah, Dahyun Oh, Katy C. Kao

Faculty Research, Scholarly, and Creative Activity

Coatings with antibiofilm properties are desirable for biomedical applications. Titanium dioxide (TiO2) has been explored as an antimicrobial agent in materials development primarily due to it being an excellent photocatalyst. Candida glabrata (C. glabrata) is an emerging human fungal pathogen with known high resistance to oxidative stress. Here, we fabricated a polydimethylsiloxane/titanium dioxide (PDMS/TiO2) nanocomposite coating and tested its antibiofilm activities against C. glabrata. The resulting nanocomposite exhibited >50% reduction in C. glabrata biofilm formation with 2.5 wt % TiO2 loading, even in the dark. Through ROS detection and surface characterization, the antibiofilm activity was attributed to the synergistic interaction …

Who’S Actually Afraid Of Artificial Intelligence (Ai?), Anthony Adeloye

Library Philosophy and Practice (e-journal)

Purpose of the study: The main purpose of the study is to explore and discuss the views of a group of Nigerian academic librarians about Artificial Intelligence (AI). The study is considered important because a perusal of an academic librarian’s role requires the ability to organise and manage knowledge which invariably entails the use of some sort of technology which in the context of this study, is artificial intelligence (AI).

Method: To understand the degree to which academic librarians in Nigeria perceive the role of AI in academia, and indeed, society, data were collected from an online survey that …

The Piper Survey. Ii. The Globular Cluster Systems Of Low Surface Brightness Galaxies In The Perseus Cluster, Steven R. Janssens, Duncan A. Forbes, Aaron J. Romanowsky, Jonah Gannon, Joel Pfeffer, Warrick J. Couch, Jean P. Brodie, William E. Harris, Patrick R. Durrell, Kenji Bekki

Faculty Research, Scholarly, and Creative Activity

We present Hubble Space Telescope ACS/WFC and WFC3/UVIS imaging for a sample of 50 low-surface brightness (LSB) galaxies in the ∼ 1015 M☉ Perseus cluster, which were originally identified in ground-based imaging. We measure the structural properties of these galaxies and estimate the total number of globular clusters (GCs) they host. Around half of our sample galaxies meet the strict definition of an ultra-diffuse galaxy (UDG), while the others are UDG-like but are either somewhat more compact or slightly brighter. A small number of galaxies reveal systems with many tens of GCs, rivalling some of the richest GC systems known …

Mixed Methods Study Protocol: Language Identity, Discrimination, And Mental Health Among Multilingual 1.5 Generation Asian/Asian American Immigrant Young Adults, Chulwoo Park, Mark Edberg, Janet Yougi Bang, Avizia Yim Long

Faculty Research, Scholarly, and Creative Activity

Language identity, an understudied factor, can influence isolation and discrimination, leading to disparities in well-being and mental health among immigrants. This study aims to investigate the role of language identity on structural racism and discrimination among 1.5 generation Asian/Asian American immigrants in a diverse U.S. state. We developed a three-step sequential approach: Stage 1—qualitative analysis (1A, focus group discussion; 1B, in-depth interviews); Stage 2—quantitative analysis (2A, language identity measurement scale; 2B, cross-sectional online survey; 2C, multivariate multiple linear regression); Stage 3—another round of qualitative analysis (3A, follow-up in-depth chronological interviews). Therefore, this study will contribute to the field by introducing …

Healthy From The Start: Co-Designing Sleep, Nutrition And Physical Activity Resources For Young Shiftworkers—Novel Implementation And Evaluation, Alexandra E. Shriane, Sally A. Ferguson, Gabrielle Rigney, Charlotte C. Gupta, Tracy Kolbe-Alexander, Madeline Sprajcer, Cassie Hilditch, Robert Stanton, Matthew J.W. Thomas, Jessica L. Paterson, Jamie Marino, Grace E. Vincent

Faculty Research, Scholarly, and Creative Activity

Introduction: The increasing prevalence of shiftwork among young adults poses significant health risks, primarily due to its disruptive effects on sleep, nutrition and physical activity. Addressing these risks necessitates the development of tailored, evidence-based resources to support these key health behaviours. Participatory research approaches, engaging those with relevant lived experience (i.e., co-design) are a novel and effective approach in developing these resources. As such, the aim of the present study was to explore whether sleep, nutrition and physical activity resources for young shiftworkers could be developed using participatory, co-design approaches and how co-designers would rate both the approaches used and …

Breakdown Of Boltzmann-Type Models For The Alignment Of Self-Propelled Rods, Patrick Murphy, Misha Perepelitsa, Ilya Timofeyev, Matan Lieber-Kotz, Brandon Islas, Oleg A. Igoshin

Faculty Research, Scholarly, and Creative Activity

Studies in the collective motility of organisms use a range of analytical approaches to formulate continuous kinetic models of collective dynamics from rules or equations describing agent interactions. However, the derivation of these kinetic models often relies on Boltzmann's “molecular chaos” hypothesis, which assumes that correlations between individuals are short-lived. While this assumption is often the simplest way to derive tractable models, it is often not valid in practice due to the high levels of cooperation and self-organization present in biological systems. In this work, we illustrated this point by considering a general Boltzmann-type kinetic model for the alignment of …

Library Philosophy and Practice (e-journal)

Purpose: This study aims to examine the awareness and perception regarding the relevance of adopting blockchain technology for managing digital archives in academic libraries, Nigeria.

Design/methodology/approach: Ten system librarians who were chosen from five distinct academic libraries in Nigeria's Southwest geopolitical zone serve as the study's sample. An open-ended survey was used to gather data for the study, which took a strictly qualitative approach.

Findings: Based on the findings, system librarians are aware of blockchain technology adoption and its benefits for digital archive management in academic libraries. The adoption of blockchain technology is perceived positively since it can help …

Solvation Free Energy In Governing Equations For Dna Hybridization, Protein–Ligand Binding, And Protein Folding, Caroline Harmon, Austin Bui, Jasmin M. Espejo, Marc Gancayco, Jennifer M. Le, Juan Rangel, Daryl K. Eggers

Faculty Research, Scholarly, and Creative Activity

This work examines the thermodynamics of model biomolecular interactions using a governing equation that accounts for the participation of bulk water in the equilibria. In the first example, the binding affinities of two DNA duplexes, one of nine and one of 10 base pairs in length, are measured and characterized by isothermal titration calorimetry (ITC) as a function of concentration. The results indicate that the change in solvation free energy that accompanies duplex formation (ΔGS) is large and unfavorable. The duplex with the larger number of G:C pairings yields the largest change in solvation free energy, ΔG …
