Habitat And Conditions Of Poisoning Of Toxic Plants In North America, Michael H. Ralphs

Poisonous Plant Research (PPR)

This paper presents a list of important poisonous plants in North America that are toxic to both livestock and humans. The aim of this paper is to present information to help reduce the risk of poisoning. The paper emphasizes the particular plant communities in which these plants grow. Some of these plants are endemic, growing on specific soils or specific ecological sites. Others are distributed more broadly throughout a vegetation type. A few of the plants are widespread, ranging over several broad ecosystems. In diagnosing poisoning, it is important to know what plants are expected to grow in the communities …

Demonstration Of Coherent Optical Phase-Shift Keying With A Watt-Class 1550 Nm Tapered Diode Laser Amplifier For Free-Space Optical Communication Applications, Charlotte K. Duda, Aaron Cross, Chadwick Lindstrom, Julie Smith

Space Dynamics Laboratory Publications

High-power semiconductor optical amplifiers (SOAs) are a promising alternative to erbium-doped fiber amplifiers (EDFAs), which typically amplify the weak signals used in free-space optical (FSO) communications. In this work, we demonstrate that an Aura TM SOA operating with 1 W output power can be used to transmit phase-shift key (PSK) protocols required of next-generation FSO communication networks. Firstly, we demonstrate successful transmission of binary phase-shift keying (BPSK) for bit rates up to 50 Gbps. Secondly, we demonstrate successful transmission of quadrature phase-shift keying (QPSK) for bit rates up to 100 Gbps. For both PSK protocols, we demonstrate comparable constellation error-vector …

Evaluating The Response Of Ageing Rc Bridge Piers To The 2023 Kahramanmaraş Earthquake Using Bouc-Wen Hysteretic Models, Negin Fayaz, S. Kocakaplan Sezgin, E. Ahmadi, M. M. Kashani, M. Zaker Esteghamati

Civil and Environmental Engineering Student Research

This study examines the seismic response of reinforced concrete (RC) bridge piers subjected to ground motion (GM) records from the 2023 Kahramanmaraş earthquake by comparing the impact of pulse-like versus no-pulse records. A suite of 300 nonlinear Bouc-Wen hysteretic models was developed to represent piers with varying nonlinear behavior. Each Bouc-Wen model was assessed under 24 pulse-like and 28 no-pulse GMs, resulting in 15,600 nonlinear time-history simulations. Subsequently, the relationship between Bouc-Wen parameters (i.e., period and yield displacement) and seismic responses (i.e., maximum displacement, residual displacement, and maximum acceleration) was analyzed. The results show that pulse-like records produce 5 times …

When The Student Surpasses The Teacher: Better Generalization In Ai-Based Seismic Waveform Quality Assessment Using Knowledge Distillation, Ali Namin, F. Jalaeifar, A. Kottke, M. Zaker Esteghamati

Civil and Environmental Engineering Student Research

This paper presents a knowledge distillation (KD)-based approach to reduce computational expenses and improve the generalizability of deep learning-based models for quality assessment of seismic waveforms. Using two different waveform datasets, teacher models are distilled into lightweight student models from two families of time-series-based and image-based models. Models from both student families are trained on a development dataset and evaluated on the testing portion of the development dataset, as well as on an entirely different external testing dataset. Results indicate that KD can provide student models with substantially reduced size (5%-10% of the teacher model's size) and latency while preserving, …

A Context-Aware Computer Vision-Based Approach For Post-Earthquake Damage Assessment Of Bridge Inventories, Parham Bakhtiari, S. Ratna Pandey, M. Zaker Esteghamati

Civil and Environmental Engineering Student Research

Post-earthquake damage assessment is crucial to evaluate the safety and serviceability of bridges after an earthquake. Conventional screening methods rely on manual inspection, which is costly, time-consuming, and poses safety risks to inspectors. To address these challenges, this study presents a context-aware vision transformer framework for integrating structural element details into multi-defect identification through a late-fusion approach. The model is trained on a post-earthquake image dataset collected from three major earthquakes in Italy, consisting of 356 images. Five structural elements of reinforced concrete bridges are selected, where concrete spalling and reinforcement corrosion were chosen as target defects. The framework achieved …

On Signifiable Computability: Part Iii: A Note On Unnameable Functions On Natural Numbers, Vladimir A. Kulyukin

Computer Science Faculty and Staff Publications

A writing system 𝔚 on an alphabet 𝒜 is a tuple (ℜ,𝔐), where ℜ is a finite set of text formation rules and 𝔐 is a finite rule application mechanism that generates texts on 𝒜. A natural writing system forms natural language texts on an alphabet such as Sanskrit on Devanagari. An artificial writing system generates formal language texts on an alphabet such as Lisp on Unicode. Let ℕ ={0,1,2,…} be the set of natural numbers. A function on natural numbers 𝑓 :ℕ^𝑘 ↦ ℕ, 0 < 𝑘 ∈ ℕ, is nameable by a writing system on an alphabet if, and only if, the system can generate a text on the alphabet that names f and no other function. We show that there exist functions on natural numbers unnameable in principle in that they cannot be named by any writing system on any alphabet. Our results imply the following computability-theoretic hierarchy of functions on natural numbers: computable ⊊ partially computable ⊊ nameable ⊊ 𝔉, where 𝔉 is the set of functions on ℕ.

How A 2 To 5-Year Experimental Lake Powell And Lake Mead Release Program Tied To Reservoir Inflows Can Be A Win For Adaptive Risk Management, Brittany Fager, Anabelle Myers, Erik Porse, David Rosenberg

Civil and Environmental Engineering Faculty Publications

Lake Powell and Lake Mead are at risk of drawdown to their minimum power and dead pools in the next few years because current and proposed shortage and release operations tied to reservoir storage and sometimes prior natural flow cannot keep pace with U.S. Bureau of Reclamation’s numerous scenarios of more volatile, declining, and longer-lasting periods of low flows. One experimental program to reduce risk can instead adapt reservoir releases to monitored changes in physical reservoir inflow and reservoir evaporation. First, stabilize reservoir storage by temporarily setting reservoir release to the physical reservoir inflow minus evaporation (the available water). Second, …

Addressing Health Inequities For People With Intellectual And Developmental Disabilities In The Hospital Through Partnerships In Nurse Training, Suzannah Iadarola, Amanda Laprime, Samantha Hochheimer, Tabby Anvari, Carrie Baker, Jacqueline Goodman

Developmental Disabilities Network Journal

People with intellectual/developmental disabilities (IDD) deserve the same access to quality healthcare yet are at increased risk of medical and/or psychiatric conditions as compared to the general population. Patients with IDD have less health satisfaction, shorter life expectancy, less access to preventative care, higher chronic health conditions, overuse of certain medications, and increased mortality. This population and their caregivers report high levels of dissatisfaction with emergency/inpatient care. Nurses also express frustration with lack of training, limited resources, and competing priorities.

We developed the Advancing Supportive Care through Education for Nurses on Disability (ASCEND) Program, to build the capacity of inpatient/Emergency …
