A Westerly Wind Dominated Puna Plateau During Deposition Of Upper Pleistocene Loessic Sediments In The Subtropical Andes, South America, Alex Pullen, David L. Barbeau Jr, Andrew Leier, Madison Ward, Austin Bruner, Mary Kate Fidler

Faculty Publications

The Tafí del Valle depression (~27° S) in the eastern Andes of Argentina provides a record of late Pleistocene dust deposition in the subtropics of South America. We present large-n U-Pb geochronology data for detrital zircons from upper Pleistocene loess-paleosol deposits. When compared to regional data, the age spectra from the Tafí del Valle samples are most like the southern Puna Plateau, supporting derivation largely from the west and northwest. This runs counter to hypotheses suggesting these loessic sediments were derived from the low elevation plains to the east or extra-Andean Patagonia. Mapping of linear wind erosion features on …

“I Survived”: Navigating A Fully Virtual Hiring Process, Mckenzie M. Lemhouse

South Carolina Libraries

The hiring process in academic libraries is often complex. The COVID-19 pandemic only complicated things further, causing the customary full-day interview and job talk to shift towards fully virtual or hybrid models. After graduating in 2020, I secured a tenure-track academic librarian role. This poster features lessons learned from my experiences in pandemic-era interviews that may help job seekers and established professionals looking to refresh their toolkit.

Duration Of Employment And Interpersonal Conflict Experienced In South Carolina Academic Libraries, Maggie Albro

South Carolina Libraries

Interpersonal conflicts occur across all relationships at all levels. Unresolved interpersonal conflicts can lead to bullying, which has been under continued exploration in the workplace since the 1990s (Keashly & Neumann, 2010). The longer someone is employed at an institution, the more time they will have to experience interpersonal conflict in their work relationships. This study uses Harvey, Blouin, & Stout’s (2006) Interpersonal Conflict Scale to examine the relationship between duration of employment and the level of interpersonal conflict experienced by South Carolina academic librarians. The results of this study indicate there is a low level of interpersonal conflict experienced …

Cis- And Trans-Resveratrol Have Opposite Effects On Histone Serine-Adp-Ribosylation And Tyrosine Induced Neurodegeneration, Megha Jhanji, Chintada Nageswara Rao, Jacob C. Massey, Marion C. Hope Iii, Xueyan Zhou, C. Dirk Keene, Tao Ma, Michael D. Wyatt, Jason A. Stewart, Sajish Mathew

Faculty Publications

Serum tyrosine levels increase during aging, neurocognitive, metabolic, and cardiovascular disorders. However, calorie restriction (CR) and sleep lower serum tyrosine levels. We previously showed that tyrosine inhibits tyrosyl-tRNA synthetase (TyrRS)-mediated activation of poly-ADP-ribose polymerase 1 (PARP1). Here, we show that histone serine-ADP-ribosylation is decreased in Alzheimer’s Disease (AD) brains, and increased tyrosine levels deplete TyrRS and cause neuronal DNA damage. However, dopamine and brain-derived neurotrophic factor (BDNF) increase TyrRS and histone serine-ADP-ribosylation. Furthermore, cis-resveratrol (cis-RSV) that binds to TyrRS mimicking a ‘tyrosine-free’ conformation increases TyrRS, facilitates histone serine-ADP-ribosylation-dependent DNA repair, and provides neuroprotection in a TyrRS-dependent manner. …

Maternal Lineage And Habitat Use Patterns Explain Variation In The Fecundity Of A Critically Endangered Baleen Whale, Ana L. Bishop, Leah M. Crowe, Philip K. Hamilton, Erin L. Meyer-Gutbrod

Faculty Publications

The critically endangered North Atlantic right whale population (Eubalaena glacialis) has experienced multiple periods of decreased reproduction within its observable history, which have played a role in the overall decline of the species. In addition to this synchronized variation in reproduction across the population, there exists considerable individual variation in fecundity. To determine the impacts of family history and habitat use behavior on these individual variations in fecundity, photo identification data collected during four decades of visual monitoring were used to create a calving index for sexually mature females that could be used to evaluate matrilineal influence on …

Chronic multisymptom illness (CMI) affects a subsection of elderly and war Veterans and is associated with systemic inflammation. Here, using a mouse model of CMI and a group of Gulf War (GW) Veterans’ with CMI we show the presence of an altered host resistome. Results show that antibiotic resistance genes (ARGs) are significantly altered in the CMI group in both mice and GW Veterans when compared to control. Fecal samples from GW Veterans with persistent CMI show a significant increase of resistance to a wide class of antibiotics and exhibited an array of mobile genetic elements (MGEs) distinct from normal …

Prisoners Of Scale: Downscaling Community Resilience Measurements For Enhanced Use, Sahar Derakshan, Leah Blackwood, Margot Habets, Julia F. Effgen, Susan L. Cutter

Faculty Publications

As improved data availability and disaster resilience knowledge help progress community resilience quantification schemes, spatial refinements of the associated empirical methods become increasingly crucial. Most existing empirically based indicators in the U.S. use county-level data, while qualitatively based schemes are more locally focused. The process of replicating resilience indices at a sub-county level includes a comprehensive study of existing databases, an evaluation of their conceptual relevance in the framework of resilience capitals, and finally, an analysis of the statistical significance and internal consistency of the developed metrics. Using the U.S. Gulf Coast region as a test case, this paper demonstrates …

Understanding Rapid Intercalation Materials One Parameter At A Time, Wessel Van Den Bergh, Morgan Stefik

Faculty Publications

Demand for fast, energy-dense storage drives the research into nanoscale intercalation materials. Nanomaterials accelerate kinetics and can modify reaction path thermodynamics, intercalant solubility, and reversibility. The discovery of intercalation pseudocapacitance has opened questions about their fundamental operating principles. For example, are their capacitor-like current responses caused by storing energy in special near-surface regions or rather is this response due to normal intercalation limited by a slower faradaic surface-reaction? This review highlights emerging methods combining tailored nanomaterials with the process of elimination to disambiguate cause-and-effect at the nanoscale. This method is applied to multiple intercalation pseudocapacitive materials showing that the timescales …

Verbal Inhibition Declines Among Older Women With High Fmr1 Premutation Expansions: A Prospective Study, Nell Maltman, Leann Dawalt, Jinkuk Hong, Audra Sterling, Elizabeth Berry-Kravis, Jessica Klusek, Marsha R. Mailick

Faculty Publications

The FMR1 premutation has been associated with difficulties in executive functioning, including verbal inhibition. However, little is known about the longitudinal profiles of verbal inhibition among FMR1 premutation carriers, particularly in women, and how individual factors such as aging and CGG repeat length may contribute to changes in verbal inhibition over time. The present study examined verbal inhibition performance (i.e., inhibition errors) on the Hayling Sentence Completion Task in a cohort of 92 women with the FMR1 premutation across two timepoints approximately three years apart. We examined the effects of age, CGG repeat length, and their interactions on verbal inhibition …

Tropospheric Attenuation Prediction For Future Millimeter Wave Terrestrial Systems: Estimating Statistics And Extremes, Jinwen Liu, David W. Matolak, Ismail Güvenç, Hani Mehrpouyan

Faculty Publications

Tropospheric attenuations can be significant in the millimeter wave (mmWave) frequency bands; hence, accurate prediction modeling of tropospheric attenuation is important for reliable mmWave communication. Several models have been established by the International Telecommunication Union (ITU), yet estimation accuracy is limited due to the large spatial scales used for model input parameters. In this paper, we address this and apply local precipitation data to analyze tropospheric attenuation statistics and compare to results when using ITU regional input rain data. Specifically, tropospheric attenuation is predicted via simulations using the ITU method at 30, 60, and 90 GHz in four distinct geographic …

Can Coastal Habitats Rise To The Challenge? Resilience Of Estuarine Habitats, Carbon Accumulation, And Economic Value To Sea-Level Rise In A Puget Sound Estuary, Monica M. Moritsch, Kristin B. Bryd, Melanie Davis, Anthony Good, Judith Z. Drexler, James T. Morris, Isa Wood, Lisamarie Windham-Myers, Eric Grossman, Gynnis Nakai, Katrina L. Poppe, John M. Rybczyk

Sea-level rise (SLR) and obstructions to sediment delivery pose challenges to the persistence of estuarine habitats and the ecosystem services they provide. Restoration actions and sediment management strategies may help mitigate such challenges by encouraging the vertical accretion of sediment in and horizontal migration of tidal forests and marshes. We used a process-based soil accretion model (Coastal Wetland Equilibrium Model) combined with a habitat classifcation model (MOSAICS) to estimate the efects of SLR, suspended sediment, and inland habitat migration on estuarine habitats, soil carbon accumulation, and economic value of climate change mitigation of carbon accumulation (social cost of carbon dioxide) …

A Dual-Band Filtering Structure For Highly Selective Reconfigurable Bandpass Filter And Filtering Balun, Jinqun Ge, Guoan Wang

Faculty Publications

This article proposes a filtering structure consisting of two half-wavelength resonators and two open-stub loaded resonators, which generates two third-order passbands. Multiple transmission zeros are introduced by the newly developed coupling scheme, resulting in extremely sharp roll-off desirable for highly selective filters. The proposed structure is applied to design a PIN-diodes switch-controlled reconfigurable dual-band bandpass filter (BPF) with four-state filtering responses: both passbands ON, both passbands OFF, high-frequency passband ON, and low-frequency passband ON. Stepped-impedance open stubs and one-end-grounded coupled lines are studied and employed in the design to suppress unwanted responses. In addition, two filtering structures are placed symmetrically …

Institutional Betrayals As Sex Discrimination, Emily Suski

Faculty Publications

Title IX jurisprudence has a theoretical and doctrinal inadequacy. Title IX’s purpose is to protect public school students from sex discrimination in all its forms. Yet, courts have only recognized three relatively narrow forms of sex discrimination under it. Title IX jurisprudence, therefore, cannot effectively recognize as sex discrimination the independent injuries, called institutional betrayals, that schools impose on students because they have suffered sexual harassment. Institutional betrayals occur when schools betray students’ trust in or dependency on them by failing to help students in the face of their sexual harassment. These injuries cause harms that can be more severe …

The Majorana Demonstrator comprises two arrays of high-purity germanium detectors constructed to search for neutrinoless double-beta decay in 76Ge and other physics beyond the Standard Model. Its readout electronics were designed to have low electronic noise, and radioactive backgrounds were minimized by using low-mass components and low-radioactivity materials near the detectors. This paper provides a description of all components of the Majorana Demonstrator readout electronics, spanning the front-end electronics and internal cabling, back-end electronics, digitizer, and power supplies, along with the grounding scheme. The spectroscopic performance achieved with these readout electronics is also demonstrated.

Publications

Through intentionally engaging in reflexivity, researchers can be transparent about potential areas of social inquiry and analysis that might be subject to a priori assumptions, personal biases, and interpretations that are not rooted in the data. In the context of conducting research with others, reflexivity also includes a collective dimension in which each researcher’s positionality interacts with the others and shapes research outcomes. Fostering collective reflexivity within interdisciplinary teams enables the researchers to process conflicting perspectives, allow creative and innovative approaches to emerge, and develop a shared vision of the research concepts, methods, and outcomes. Despite its acknowledged value, the …

To Stick Or Not To Stick: The Multiple Roles Of Cell Adhesion Molecules In Neural Circuit Assembly, Trevor Moreland, Fabienne E. Poulain

Faculty Publications

Precise wiring of neural circuits is essential for brain connectivity and function. During development, axons respond to diverse cues present in the extracellular matrix or at the surface of other cells to navigate to specific targets, where they establish precise connections with post-synaptic partners. Cell adhesion molecules (CAMs) represent a large group of structurally diverse proteins well known to mediate adhesion for neural circuit assembly. Through their adhesive properties, CAMs act as major regulators of axon navigation, fasciculation, and synapse formation. While the adhesive functions of CAMs have been known for decades, more recent studies have unraveled essential, non-adhesive functions …

Publications

BACKGROUND:

Undernutrition threatens the health and future of preschool children in disadvantaged remote communities. Home-grown school feeding (HGSF) in nursery schools could positively impact children's nutrition while creating multiple benefits for the whole community. However, evidence is lacking on implementation of HGSF within multi-sectoral programs in remote areas.

OBJECTIVE:

This study assessed an HGSF pilot intervention, part of a nutrition-sensitive agriculture (NSA) program, in a mountain ethnic minority community in Vietnam. It aimed to identify the changes brought about by the intervention, in particular diversity of children's food, food sources, barriers and facilitators to change, and future challenges and strategies. …

Pickle Associates With Histone Deacetylase 9 To Mediate Vegetative Phase Change In Arabidopsis, Tieqiang Hu, Darren Manuela, Valerie Hinsch, Mingli Xu

Faculty Publications

• The juvenile-to-adult vegetative phase change in flowering plants is mediated by a decrease in miR156 levels. Downregulation of MIR156A/MIR156C, the two major sources of miR156, is accompanied by a decrease in acetylation of histone 3 lysine 27 (H3K27ac) and an increase in trimethylation of H3K27 (H3K27me3) at MIR156A/MIR156C in Arabidopsis.

• Here, we show that histone deacetylase 9 (HDA9) is recruited to MIR156A/MIR156C during the juvenile phase and associates with the CHD3 chromatin remodeler PICKLE (PKL) to erase H3K27ac at MIR156A/MIR156C.

• H2Aub and H3K27me3 become enriched at MIR156A/MIR156C, and the recruitment of Polycomb Repressive Complex …

Predictors Of Therapy Response In Chronic Aphasia: Building A Foundation For Personalized Aphasia Therapy, Sigfus Kristinsson, Dirk B. Den Ouden, Chris Rorden, Roger Newman-Norlund

Faculty Publications

Chronic aphasia, a devastating impairment of language, affects up to a third of stroke survivors. Speech and language therapy has consistently been shown to improve language function in prior clinical trials, but few clinicially applicable predictors of individual therapy response have been identified to date. Consequently, clinicians struggle substantially with prognostication in the clinical management of aphasia. A rising prevalence of aphasia, in particular in younger populations, has emphasized the increasing demand for a personalized approach to aphasia therapy, that is, therapy aimed at maximizing language recovery of each individual with reference to evidence-based clinical recommendations. In this narrative review, …

Attention/Deficit Hyperactivity Disorder In Adolescent And Young Adult Males With Fragile X Syndrome, Jessica Klusek, Shannon L. O'Connor, Alexandra Hickey, Kimberly J. Hills, Leonard Abbeduto, Jane E. Roberts

Faculty Publications

This study characterized the rates of rates of attention-deficit/hyperactivity disorder (ADHD) in adolescent and young adult males with fragile X syndrome (FXS) using a multi-method approach integrating a DSM-based parent interview (Children’s Interview for Psychiatric Syndromes; P-ChIPS, Fristad et al., 1998) and a parent rating scale (Child Behavior Checklist; CBCL, Achenbach, 2001). Thirty-one males with FXS, aged 16-24 years, participated. Forty-two percent met DSM-5 criteria for ADHD and 35% exceeded the CBCL cut-offs. Agreement between the two classification methods was fair (κ=0.38). Autism symptom severity and nonverbal cognitive ability did not predict ADHD diagnoses/symptoms. Results show …
