Airborne electromagnetic surveys collected in December 2011 and November 2018 and three soil sampling transects were used to analyze the spatial heterogeneity of shallow (< 4 m) soil properties in lower Taylor Valley (TV), East Antarctica. Soil resistivities from 2011 to 2018 ranged from ∼33 Ωm to ∼3,500 Ωm with 200 Ωm assigned as an upper boundary for brine-saturated sediments. Elevations below ∼50 m above sea level (masl) typically exhibit the lowest resistivities with resistivity increasing at high elevations on steeper slopes. Soil water content was empirically estimated from electrical resistivities using Archie's Law and range from ∼< 1% to ∼68% by volume. An increase in silt- and clay-sized particles at low elevations increases soil porosity but decreases hydraulic conductivity, promoting greater residence times of soil water at low elevations near Lake Fryxell. Soil resistivity variability between 2011 and 2018 shows soils at different stages of soil freeze-thaw cycles, which are caused predominantly by solar warming of soils as opposed to air temperature. This study furthers the understanding of the hydrogeologic structure of the shallow subsurface in TV and identifies locations of soils that are potentially prone to greater rates of thaw and resulting ecosystem homogenization of soil properties from projected increases in hydrological connectivity across the region over the coming decades.

Neutrino oscillation experiments require a precise measurement of the neutrino energy. However, the kinematic detection of the final-state neutron in the neutrino interaction is missing in current neutrino oscillation experiments. The missing neutron kinematic detection results in a smaller detected neutrino energy than the true neutrino energy. A novel 3D-projection scintillator tracker, which consists of roughly ten million active cubes covered with an optical reflector, is capable of measuring the neutron kinetic energy and direction on an event-by-event basis using the time-of-flight technique thanks to the fast timing, fine granularity, and high light yield. The ν¯μ interactions tend to produce …

Non-Quasiconvex Subgroups Of Hyperbolic Groups Via Stallings-Like Techniques, Pallavi Dani, Ivan Levcovitz

Faculty Publications

We provide a new method of constructing non-quasiconvex subgroups of hyperbolic groups by utilizing techniques inspired by Stallings’ foldings. The hyperbolic groups constructed are in the natural class of right-angled Coxeter groups (RACGs for short) and can be chosen to be 2-dimensional. More specifically, given a non-quasiconvex subgroup of a (possibly non-hyperbolic) RACG, our construction gives a corresponding non-quasiconvex subgroup of a hyperbolic RACG. We use this to construct explicit examples of non-quasiconvex subgroups of hyperbolic RACGs including subgroups whose generators are as short as possible (length two words), finitely generated free subgroups, non-finitely presentable subgroups, and subgroups of fundamental …

Envirome-Wide Associations Enhance Multi-Year Genome-Based Prediction Of Historical Wheat Breeding Data, Germano Costa-Neto, Leonardo Crespo-Herrera, Nick Fradgley, Keith Gardner, Alison R. Bentley, Susanne Dreisigacker, Roberto Fritsche-Neto, Osval A. Montesinos-López, Jose Crossa

Faculty Publications

Linking high-throughput environmental data (enviromics) to genomic prediction (GP) is a cost-effective strategy for increasing selection intensity under genotype-by-environment interactions (G × E). This study developed a data-driven approach based on Environment–Phenotype Association (EPA) aimed at recycling important G × E information from historical breeding data. EPA was developed in two applications: (1) scanning a secondary source of genetic variation, weighted from the shared reaction-norms of past-evaluated genotypes and (2) pinpointing weights of the similarity among trial-sites (locations), given the historical impact of each envirotyping data variable for a given site. These results were then used as a dimensionality reduction …

Discovery Of Novel Bioactive Tanshinones And Carnosol Analogues Against Breast Cancer, Miguel A. González-Cardenete, Natalia González-Zapata, Lucinda Boyd, Fatima Rivas

Faculty Publications

The abietane diterpenoids ferruginol (1), tanshinone IIA (3), and carnosol (4) are well-known for their interesting pharmacological properties, including antitumor, similar to other natural and semisynthetic abietanes. In this study, a pair of semisynthetic C18-functionalized analogues of 3 and 4 were prepared from the commercially available (+)-dehydroabietylamine or readily obtained methyl dehydroabietate. Semisynthetic ferruginol (1) and some selected analogues, together with the synthesized analogues, were tested in vitro for the inhibition of proliferation in four breast cancer cell lines, SUM149, MDA-MB231, T47D, and MCF07. As a result, several tested abietane analogues decreased cell proliferation and enhanced cell death, with IC50 …

A Roadmap To Equitable School Mental Health Screening, Stephanie Moore, Anna C.J. Long, Samantha Coyle, Jennifer M. Cooper, Ashley M. Mayworm, Samira Amirazizi, Kelly L. Edyburn, Paige Pannozzo, Danbi Choe

Department of Psychology Faculty Scholarship and Creative Works

Youth in the United States are experiencing mental health concerns at alarming rates. Considering the nation's legacy of racism and growing recognition of the impact of social determinants of health on educational and mental health inequities, it is imperative to re-envision how we approach mental health screening in schools to center equity. A focus on mental health screening for the sole purpose of identifying individual at-risk students ignores key contextual considerations, is ineffective in addressing health and educational inequities, and has the potential to perpetuate oppressive practices in schools. Equity-focused mental health screening requires a shift from individual- and deficit-focused …

Latest Research: Summary 5. A Review On The Impact Of Climate Change On Food Security And Malnutrition In The Sahel Region Of Cameroon

Journal of Nonprofit Innovation

Climate change has direct and indirect impacts on human health. One indirect impact is food insecurity, which can lead to malnutrition. In the Sahel region of Cameroon, the population regularly experiences high levels of malnutrition, because harsh climate conditions (including extreme drought) have a negative influence on agriculture. In particular, the extreme drought conditions lead to a reduction in agricultural production, an important parameter of food security.

Atypical Presentation Of Progressive Disseminated Histoplasmosis In A Patient Recently Diagnosed With Aids, Andrew Stefan, Erica Herc, Smitha Gudipati, Indira Brar, Alyssa Vitale, Zain Tariq

Infectious Diseases Articles

Opportunistic infections, including progressive disseminated histoplasmosis (PDH), may have variable and surprising presentations in patients with AIDS. This can be either a primary infection or reactivation of a latent infection. Latent infections may occur due to being unmasked by the immune reconstitution inflammatory syndrome after the initiation of combined antiretroviral therapy. PDH can be difficult to diagnose in patients with AIDS due to its variable presentation and many overlapping symptoms with other opportunistic infections. Serum and urine antigen testing are highly sensitive and typically used as the initial diagnostic test to workup suspected PDH. However, negative antigen and antibody tests …

Michigan Tech Publications, Part 1

The three-dimensional (3D) physical aspects of ecosystems are intrinsically linked to ecological processes. Here, we describe structural diversity as the volumetric capacity, physical arrangement, and identity/traits of biotic components in an ecosystem. Despite being recognized in earlier ecological studies, structural diversity has been largely overlooked due to an absence of not only a theoretical foundation but also effective measurement tools. We present a framework for conceptualizing structural diversity and suggest how to facilitate its broader incorporation into ecological theory and practice. We also discuss how the interplay of genetic and environmental factors underpin structural diversity, allowing for a potentially unique …

Teaching Narrative Interviewing: Reflecting, Narrating, And Becoming-In-Action, Brett H. Bodily, Sherri R. Colby

Faculty Publications

Qualitative inquiry teachers often seek powerful pedagogies to improve their students’ understandings. Using our experience leading a doctoral workshop, we share our method for teaching narrative interviewing using Schön’s (1983) “reflection-in-action,” meaning teachers and students reflect in the moment. We also root our pedagogy in Jerome Bruner’s (1986, 1990) narrative as a mode of thinking and a mode of being, a philosophy exploring the ways learners story their own and others’ lives. Describing our doctoral workshop, we highlight Laura, a recent graduate, narrating and becoming a qualitative inquirer. We conclude with a sample teaching lesson, designed to enhance students’ reflective …

A Multiple Association-Based Unsupervised Feature Selection Algorithm For Mixed Data Sets, Ayman Taha, Ali S. Hadi, Bernard Cosgrave, Susan Mckeever

Articles

Companies have an increasing access to very large datasets within their domain. Analysing these datasets often requires the application of feature selection techniques in order to reduce the dimensionality of the data and prioritise features for downstream knowledge generation tasks. Effective feature selection is a key part of clustering, regression and classification. It presents a myriad of opportunities to improve the machine learning pipeline: eliminating redundant and irrelevant features, reducing model over-fitting, faster model training times and more explainable models. By contrast, and despite the widespread availability and use of categorical data in practice, feature selection for categorical and/or mixed …

Astronomy: Faculty Publications

High-contrast imaging has afforded astronomers the opportunity to study light directly emitted by adolescent (tens of megayears) and “proto” (<10 >Myr) planets still undergoing formation. Direct detection of these planets is enabled by empirical point-spread function (PSF) modeling and removal algorithms. The computational intensity of such algorithms, as well as their multiplicity of tunable input parameters, has led to the prevalence of ad hoc optimization approaches to high-contrast imaging results. In this work, we present a new, systematic approach to optimization vetted using data of the high-contrast stellar companion HD 142527 B from the Magellan Adaptive Optics Giant Accreting Protoplanet …
