Luminescence Dating Of Hydrothermal Explosions In The Yellowstone Plateau Volcanic Field, Karissa Cordero, Nathan D. Brown, Lauren N. Harrison, Shaul Hurwitz

Earth & Environmental Sciences Datasets - Archive

Hydrothermal explosions are a significant geological hazard in some active volcanic systems; however, the timing and triggering mechanisms of these explosions are poorly constrained. This study applies luminescence dating techniques to hydrothermal explosion deposits in the Yellowstone Plateau volcanic field to constrain explosion chronologies and evaluate potential triggering mechanisms. We tested four luminescence dating techniques: K-feldspar post-infrared infrared stimulated luminescence (pIRIR225), quartz blue light optically stimulated luminescence (BLOSL), quartz blue thermoluminescence (BTL), and quartz red thermoluminescence (RTL). The pIRIR225 and RTL protocols produce consistent age estimates that agree with independent radiocarbon ages and with the timing of the Pinedale deglaciation. …

BACKGROUND: Physical activity fragmentation represents the frequency of transitioning from an active to sedentary state. The prognostic information of physical activity fragmentation is unclear in Hispanics/Latinos. This study examined the association of PA fragmentation with all-cause mortality in Hispanic/Latino adults.

METHODS: We investigated 11,992 participants from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) (18-74 yr; 52.2% women), from four United States urban communities (Bronx, New York; Chicago, Illinois; Miami, Florida; San Diego, California), that wore an accelerometer for one week. Physical activity fragmentation was calculated using the active-to-sedentary transition probability (ASTP) as the reciprocal of the average active bout …

Faculty, Staff and Students Publications

OBJECTIVE: Rett syndrome (RTT) and MECP2 duplication syndrome (MDS) result from under- and overexpression of MECP2, respectively. Preclinical studies using genetic-based treatment showed robust phenotype recovery for both MDS and RTT. However, there is a risk of converting MDS to RTT, or vice versa, if accurate MeCP2 levels are not achieved. The aim of this study was to identify biomarkers distinguishing RTT from MDS.

MATERIALS AND METHODS: We prospectively enrolled 11 MDS and 6 male RTT like (MRL) individuals for a panel of clinical and neurophysiological assessments over two visits, 8-10 months apart.

RESULTS: We identified numerous clinical and physiological …

Predictors Of Bi-Directional Transitions From Mild Cognitive Impairment In A Diverse Cohort, Mitzi M. Gonzales, Roman Fernandez, Sarah Kremen, Zaldy S. Tan, Amy E. Werry, Xueqiu Jian, John Hart, Donald Royall, Gladys Maestre, Sara Espinoza

School of Medicine Publications

Trajectories following a diagnosis of mild cognitive impairment (MCI) are varied and may fluctuate over time. Among diverse ethnic and racial groups, social factors, medical comorbidities, and biases in assessment procedures may contribute to greater heterogeneity in the MCI diagnostic category and affect its prognostic significance for dementia. The study goal was to evaluate the frequency and variables associated with MCI transitions among non-Hispanic White (NHW) and Latinx older adults. Multistate Markov models characterized transitions across diagnostic states (cognitively unimpaired (CU), MCI, dementia) over ten years. Variables associated with transitions were assessed using hazard ratios (HR) and 95% confidence intervals …

A Living Feminist Postdevelopmental Lexicon For Early Education, Mindy Blaise, Veronica Pacini-Ketchabaw

Research outputs 2022 to 2026

Expanding the important body of work that addresses child development’s limitations and responding to the ecological crisis that threatens the future of life on Earth, this article proposes a living feminist postdevelopmental lexicon. The lexicon introduces 26 concepts that together challenge the theory/practice divide, disrupt Cartesian modes of subjectivity, reorient taken-for-granted ideas as problematic in early education, open up early education to inquiries that respond to the political and ethical questions of our milieu, and generate conditions for creative, inventive, thoughtful, and ethical projects. The paper invites readers to engage with and creatively add to the lexicon, making it an …

Constanto Mysterium - A Paradise Of Shifting Constants, Vijay Fafat

Journal of Humanistic Mathematics

Mathematicians speak of constants of mathematics. Some of these constants are known to high-heavens. Some remain hidden in the obscurity of erudition. And to be frank, while every real number is a mathematical constant, we don’t know much about most of them (is not the set of transcendental numbers incommensurable without us knowing or understanding very many of them?).

So what elevates some constants above others? Is this elevation just a measure of the ignorance of mathematicians who have explored but a small patch of an infinite quilt, a case of six wise men trumpeting the – well, the trumpet …

A Ramsey Theory Essay: The Dinner Party, Ryan Coghill

Journal of Humanistic Mathematics

This is a poem inspired by Ramsey’s theorem. Its main characters are; Frank Ramsey, Issai Schur, Richard Rados, Bertel van der Waarden, Ronald Graham and Paul Erdos, some of the pioneers of the field of Ramsey theory. There has been care put into each paragraph so that it’s lines can be viewed as though they were nodes on a graph which share traits with each other of rhyme, theme and length which can be paired in 2 states, sharing and unique in such a way that one might find coloured graph edges when working in the field of Ramsey theory.

Math Is A Tiger And A Pecan, William Cocke

Journal of Humanistic Mathematics

Using perfect secrecy and the ability to identify gibberish in a given language, we encode two poems in one. This allows for a single cipherpoem to have multiple plainpoems associated with it. The result is a form of superposition where neither poem is the more correct interpretation than the other.

The poem presented is about two distinct aspects of mathematics: the tiger to be sought after and hunted; or a pecan that we have surrounded but cannot crack open.

Our activities offer a mathematical exploration that requires only basic school-level mathematics, highlighting the close connection between mathematics and art.

White Horses In The Sky: Or The Magical Place Where Topology Meets Poetry, Sanziana Caraman, Lorelei Caraman

Journal of Humanistic Mathematics

What do Shakespearean words, doughnuts, cups of tea, and horses in the sky all have in common with a famous theorem? To discover the answer, we take you on a journey in a strange, enchanted land: the land where mathematics meets poetry. Here we explore how a fundamental literary trope, metaphor, and a fundamental result in topology, Brouver's Fixed Point Theorem, touch and illuminate one another. Delving into the symmetry of this transdisciplinary embrace, we find that it reveals, not only the beauty of poetry and mathematics, but that of life itself: the beauty hidden in ordinary things like a …

From The Symbol Of Inanna To Islamic Tessellations: Aesthetics Of Constructibility, Zhexiu Tu

Journal of Humanistic Mathematics

We introduce a special symbol with a long history dating back to the Sumerian period. This symbol, which was first associated with the goddess Inanna, can be constructed with compass and straightedge, a property defined as constructibility in modern geometry. Nineteenth-century mathematicians proved systematically what types of polygons and polygrams are constructible. This algebraic result shared a striking consistency with the tessellations present in medieval Islamic architecture. The geometric patterns behind the tessellations as well as the symbol of Inanna itself, if properly remodeled, can be adopted as effective tools in the teaching of algebra and Galois theory.
