IGC Proceedings (1993-2023)

Brazil has over 80 million ha of tropical pastures formed with species of Brachiaria (syn. Urochloa), mostly grazed by beef cattle and with low fertilizer inputs, especially nitrogen. Recent investigations by our team show that stoloniferous legumes such as forage peanut (Arachis pintoi) and Desmodium ovalifolium are able to persist in mixed swards with Brachiaria brizantha (cv. Marandu) if grazing height is regulated (maximum 30 cm) so that radiation can reach the soil surface allowing stolons to take root. These legumes can persist in mixed pastures and produce milk or animal weight gains similar to the application …

Ecosystem Benefits Of Invasive Annual Grass Removal, S. L. Clark

IGC Proceedings (1993-2023)

Invasive winter annual grasses (IAGs) are altering rangeland ecosystems across millions of hectares in the western US. These winter annuals outcompete native plants for soil moisture and nutrients, leading to devastating impacts on ecosystem functions. The IAG seedbank is short-lived and often does not persist beyond 3 years. Past tools for IAG control have only provided short-term control or caused injury to the native plant community, making it difficult for researchers to assess the ecosystem benefits of IAG removal. A newer herbicide option, indaziflam, provides IAG control for three or more years. Indaziflam’s extended soil residual control and tolerance of …

Annual Research Symposium

The scope of practice for pharmacists first expanded in California and Oregon with the ability to prescribe hormonal contraceptives to patients in their communities. Since 2016, over 33 states now allow for pharmacist prescribing of birth control in their pharmacy practice laws.

90% of Americans live within 5 miles of a retail pharmacy, making community pharmacies an accessible resource who may otherwise be unable to access contraceptives. The gap in care experienced by certain patient populations is now being filled by pharmacists with their ability to prescribe birth control.

A Brief Early History Of The Unlv Department Of Geoscience, Matthew S. Lachniet

Geoscience Faculty Research

This project represents four years of part-time research and investigation. It started as something simple, a need for a spreadsheet for me, as a new Department Chair in January of 2020, to assemble the tenure and promotion timelines of existing faculty based on their employment starting dates. It then expanded to document every Geoscience faculty member, which revealed so many interesting stories along the way. Once it began it was hard to stop, with the research taking on a mind of its own as it meandered down the historical archive of the Department. And why stop with people? Buildings? Fair …

Analysis Of Legacy Gravity Data Reveals Sediment-Filled Troughs Buried Under Flathead Valley, Montana, Usa, Ali Gebril, Mohamed A. Khalil, Robert Matthew Joeckel, James Rose

Conservation and Survey Division

Shallow, dominantly silt- and clay-filled erosional troughs in Quaternary sediments under the Flathead Valley (northwestern Montana, USA) are very likely to be hydraulic barriers limiting the horizontal flow of groundwater. Accurately mapping them is important because of increasing demand for groundwater.We used a legacy Bouguer gravity map measured in 1968. The directional derivatives of the map are computed, and the map was enhanced by implementing edge detection tools.We produced generalized derivative, maximum horizontal gradient, total gradient and tilt gradient maps through two-dimensional Fourier transform analysis. These maps were remarkably successful in locating buried troughs in the northern and northwestern parts …

Using A Two-Way Engagement Community- And Family-Centered Pedagogy To Prepare Pre-Service Mathematics Teachers In A Hispanic-Serving Institution, Olga Ramirez, Mayra Ortiz Galarza, Luis M. Fernandez

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

Research on effective methods to prepare pre-service teachers (PSTs) in teaching mathematics to K-12 Latin* students has been gaining significant momentum. These efforts have focused, in part, on promoting pedagogical practices that recognize and incorporate the culture and language that K-12 Latin* students and their communities share. As teacher educators, we argue that if we are to further prepare PSTs to serve the needs of such increasingly diversifying K-12 student population, the same pedagogical focus on the learner’s cultural wealth should also be applied to the preparation of PSTs themselves, especially among Latin* PSTs in Hispanic Serving Institutions (HSI) like …

Functional Data Learning Using Convolutional Neural Networks, Jose Galarza, Tamer Oraby

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

In this paper, we show how convolutional neural networks (CNNs) can be used in regression and classification learning problems for noisy and non-noisy functional data (FD). The main idea is to transform the FD into a 28 by 28 image. We use a specific but typical architecture of a CNN to perform all the regression exercises of parameter estimation and functional form classification. First, we use some functional case studies of FD with and without random noise to showcase the strength of the new method. In particular, we use it to estimate exponential growth and decay rates, the bandwidths of …

Development Of An Empirical Ground-Motion Model For Post-Mining Induced Seismicity Near Gardanne, France, Pierre Gehl, Pascal Dominique, Hideo Aochi, Mickael Delatre, Jannes Kinscher, Isabelle Contrucci

Journal of Sustainable Mining

Since the closure of mining activities in 2003, the coal basin of Gardanne in South-East France has experienced thousands of small-magnitude earthquake events, mostly triggered by the flooding of mine workings. Some of these events have been powerful enough to be strongly felt by the population, generating nuisance and concern about potential damage to buildings. The aim of this study is to improve the characterisation of the level of ground motion at the surface, by developing a ground-motion model for post-mining induced seismicity, based on several years of recorded data. A Bayesian-based method is applied to the data in order …

Improving The Proof Of The Born Rule Using A Physical Requirement On The Dynamics Of Quantum Particles, Yakir Aharonov, Tomer Shushi

Mathematics, Physics, and Computer Science Faculty Articles and Research

We propose a complete proof of the Born rule using an additional postulate stating that for a short enough time Δt between two measurements, a property of a particle will keep its values fixed. This dynamical postulate allows us to produce the Born rule in its explicit form by improving the result given in [1]. While the proposed postulate is still not part of the quantum mechanics postulates, every experiment obeys it, and it cannot be deduced using the standard postulates of quantum mechanics.
