Processing And Characterization Of Non-Speech Human Sounds -- A Step Towards Automatic Reporting Of Respiratory Disease Symptoms, Sudip Vhaduri, Siva Simhadri, Katherine S. Xiong, Bethany Grace Tennyson

Discovery Undergraduate Interdisciplinary Research Internship

Non-speech human sounds, such as coughing and wheezing are common symptoms of many respiratory diseases, including chronic obstructive pulmonary disease (COPD), asthma, and COVID-19. Thereby, an objective reporting of these symptoms from smartphone microphones can help physicians to monitor and treat patients with different respiratory diseases. However, most often audio recordings from smartphones come with different types of background noises and other non-desired sounds, such as laughing, crying, and snoring. Therefore, it is crucial to first process the raw audio clips to extract desired events, such as coughing and wheezing. In our work, we use the Audacity desktop application to …

Hhl Algorithm On The Honeywell H1 Quantum Computer, Adrik B. Herbert, Eric A. F. Reinhardt May 2022

Hhl Algorithm On The Honeywell H1 Quantum Computer, Adrik B. Herbert, Eric A. F. Reinhardt

Discovery Undergraduate Interdisciplinary Research Internship

The quantum algorithm for linear systems of equations (HHL algorithm) provides an efficient tool for finding solutions to systems of functions with a large number of variables and low sensitivity to changes in inputs (i.e. low error rates). For complex problems, such as matrix inversion, HHL requires exponentially less computational time as compared with classical computation methods. HHL can be adapted to current quantum computing systems with limited numbers of qubits (quantum computation bits) but a high reusability rate such as the Honeywell H1 quantum computer. Some methods for improving HHL have been proposed through the combination of quantum and …

Managing Humidity In Electronics Using Water Vapor-Selective Membranes, Songhao Wu, Andrew J. Fix, Allison Mou, David M. Warsinger, James Braun May 2022

Managing Humidity In Electronics Using Water Vapor-Selective Membranes, Songhao Wu, Andrew J. Fix, Allison Mou, David M. Warsinger, James Braun

Discovery Undergraduate Interdisciplinary Research Internship

Abstract: As outdoor electronics have become prevalent in every aspect of daily life, handling humidity in them is an emerging issue for reliable devices. As water vapor enters the electronics enclosure, there is a risk of condensation, which could prevent the electronics from functioning and further damage the device. Traditionally, the humidity removal for electronics is usually done by heating the air within the enclosure, which can be energy-intensive and less efficient. Vapor selective membrane systems are promising alternatives for air heating dehumidification as they do not require heating energy for water vapor removal. It allows water vapor transport through …

A Systems Approach To Studying Online Communities, Jeremy Foote Apr 2022

A Systems Approach To Studying Online Communities, Jeremy Foote

Purdue University Libraries Open Access Publishing Fund

Much early communication research was inspired by systems theory. This approach emphasizes that individuals and groups use communication to interact with and respond to their larger environment and attempts to outline the ways that dif‐ ferent levels interact with each other (e.g., work groups within departments within firms). Many concepts from systems theory—such as emergence and feedback loops—have become integral parts of communication theories. However, until recently, quantitative researchers have struggled to apply a systems approach. Large‐scale, multilevel trace data from online platforms combined with computational advances are enabling a turn back toward systems‐inspired research. I out‐ line four systems‐based …

Human papillomavirus (HPV) vaccination rates in the U.S. are relatively low. Provider recommendation rates for HPV vaccination often vary by patient age and relationship status. Obstetrician/gynecologists (OB/GYNs) represent a key provider group that can recommend the HPV vaccine. This study examined differences in OB/ GYN recommendation of HPV vaccination for inpatient postpartum patients by age, parity, and marital status. Data were collected from OB/GYNs nationally via a cross-sectional survey. Participants were randomized to two vignette groups (23-year-old patient or 33-year-old patient). Within each group, participants received 4 vignettes that were identical except for patient marital status (married/not in a committed …

Regulator Of G Protein Signaling 2 Inhibits Gαq-Dependent Uveal Melanoma Cell Growth, Qian Zhang, Andrew J. Haak, Benita Sjogren Apr 2022

Regulator Of G Protein Signaling 2 Inhibits Gαq-Dependent Uveal Melanoma Cell Growth, Qian Zhang, Andrew J. Haak, Benita Sjogren

Purdue University Libraries Open Access Publishing Fund

Activating mutations in Gαq/11 are a major driver of uveal melanoma (UM), the most common intraocular cancer in adults. While progress has recently been made in targeting Gαq/11 for UM therapy, the crucial role for these proteins in normal physiology and their high structural similarity with many other important GTPase proteins renders this approach challenging. The aim of the current study was to validate whether a key regulator of Gq signaling, regulator of G protein signaling 2 (RGS2), can inhibit Gαq-mediated UM cell growth. We used two UM cell lines, 92.1 and Mel-202, which both contain the most common activating …

Promoting The Use Of Advanced Technologies For Sustainable Charcoal And Biochar Production In Developing Countries, Francis Asare, Rado Gazo, Eva Haviarova, Francis Owusu Apr 2022

Promoting The Use Of Advanced Technologies For Sustainable Charcoal And Biochar Production In Developing Countries, Francis Asare, Rado Gazo, Eva Haviarova, Francis Owusu

FNR Annual Poster Competition

Fabricating a small-scale and cost-effective biochar/charcoal retort is most economical when farmers/producers have the materials on hand and the skills (i.e., welding) to manufacture it since inappropriate technologies affect the yield and quality of biochar. As farmers gain more knowledge and skills in manufacturing these different technologies at their convenience, they could make the right choices in subsequent years ahead and advocate sustainable agricultural practices. We analyzed existing technologies in Indiana and Ghana using desk study, questionnaires and interviews as we give recommendations on the design properties of some appropriate charcoal and biochar conversion methods for small scale usage based …

Effects Of Per- And Polyfluorinated Alkyl Substances (Pfas) On Amphibian Body Condition: Is Altered Lipid Metabolism The Driver?, Anna Bushong, Tyler Hoskins, Maria Sepulveda Apr 2022

Effects Of Per- And Polyfluorinated Alkyl Substances (Pfas) On Amphibian Body Condition: Is Altered Lipid Metabolism The Driver?, Anna Bushong, Tyler Hoskins, Maria Sepulveda

FNR Annual Poster Competition

Per- and polyfluoroalkyl substances (PFAS) are globally distributed contaminants with widespread use in commercial and consumer products. Due to their aquatic and terrestrial life cycle, amphibians are particularly susceptible to sublethal effects of PFAS exposure and are regularly exposed in the field. In amphibians experimentally-exposed to PFAS, body condition, measured using the scaled mass index (SMI), is often affected. In vitro and rodent studies have demonstrated that PFAS can alter lipid metabolism, but whether changes in fat stores can explain previously observed PFAS-mediated changes in amphibian SMI remains unexplored. Because lipids are a primary fuel for anuran metamorphosis and reproduction, …

Resistance Against Walnut Twig Beetle (Pityophthorus Juglandis) In Black Walnut (Juglans Nigra), Scott Gula, John Couture, Matthew Ginzel Apr 2022

Resistance Against Walnut Twig Beetle (Pityophthorus Juglandis) In Black Walnut (Juglans Nigra), Scott Gula, John Couture, Matthew Ginzel

FNR Annual Poster Competition

Eastern black walnut (Jug/ans nigra), an economically important tree species, is threatened by thousand cankers disease (TCD) which is caused by the fungal pathogen Geosmithia morbida and vectored by the walnut twig beetle (WTB, Pityophthorus juglandis). Control options for this disease are limited, but breeding walnut for resistance to WTB could offer a solution. There is currently no high-throughput assay to screen host trees for resistance to WTB, which is a prerequisite for identifying resistant walnut varieties. Here, we describe preliminary results of a rapid assay to measure WTB resistance in walnut. This assay is rapid, quantifiable, and can be …

FNR Annual Poster Competition

Mounting evidence suggests that geographic ranges of tree species worldwide are shifting under global environmental changes. Little is known, however, about whether and how this substantial migration of tree species may cause an overall type of forest as an ensemble of one or more tree species to migrate out of its geographic range. Here, using ground-sourced forest inventory data from 596,282 sample plots with repeated measurements, we classified forested regions in North America into eight biomes and 43 forest types, and further quantified forest migration – the shift in the geographic range of these forest types over the past 50 …

A Post Establishment Analysis Of Various Thinning Decisions For Black Walnut Plantations, Sayon Ghosh, Mike Saunders, Jim Warren, Lenny Farlee, Liz Jackson, Jingjing Liang, Mo Zhou Apr 2022

A Post Establishment Analysis Of Various Thinning Decisions For Black Walnut Plantations, Sayon Ghosh, Mike Saunders, Jim Warren, Lenny Farlee, Liz Jackson, Jingjing Liang, Mo Zhou

FNR Annual Poster Competition

In the Central Hardwood Region, the quantity and quality of hardwood timber critically depend on forest management decisions made by landowners. We fill a key gap in hardwood management by building a spatially explicit thinning model for black walnut to guide the first pre-commercial thin under user defined planting density, pre-establishment seedling survival and post establishment crop tree choices. We fmd that growth and yield of individual trees is influenced by multiple synergistic choices made during the pre-establishment and postestablishment phase. Later, we link our model with the Forest Vegetation Simulator (FVS) to project stand attributes under the impact of …

Is Toxicity Of Perflurooctanesulfonic Acid Mediated By Salinity In Estuarine Larvae And Embryos?, Meredith Scherer, Lucy Burcham, Grace Coogan, Anna Bushong, Matthew Hamilton, Sini Machery, Elizabeth Allmon, Maria Sepulveda, Tyler Hoskins Apr 2022

Is Toxicity Of Perflurooctanesulfonic Acid Mediated By Salinity In Estuarine Larvae And Embryos?, Meredith Scherer, Lucy Burcham, Grace Coogan, Anna Bushong, Matthew Hamilton, Sini Machery, Elizabeth Allmon, Maria Sepulveda, Tyler Hoskins

FNR Annual Poster Competition

Per- and polyfluoroalkyl substances (PFAS) are a class of ubiquitous environmental contaminants commonly found in estuarine environments. Estuaries are dynamic systems with regular, dramatic fluctuations in abiotic factors such as salinity, dissolved oxygen, and temperature. Despite this, how abiotic factors mediate PFAS toxicity remains unexplored. We tested the hypothesis that salinity mediates toxicity of perfluorooctane sulfonate (PFOS) in embryonic and larval sheepshead minnows (Cyprinodon variegatus; a model estuarine fish). In two factorial experiments, we exposed embryos through hatching and larvae to PFOS for 96 hours at 1, 10, 100, 1,000, and 10,000 parts per billion (ppb) across two salinity levels …

Effect Of Density On Growth Rates Of Captive Eastern Hellbenders (Cryptobranchus Alleganiensis Alleganiensis), Summer Brown, Shelby Royal, Nick Burgmeier, Rod Williams Apr 2022

Effect Of Density On Growth Rates Of Captive Eastern Hellbenders (Cryptobranchus Alleganiensis Alleganiensis), Summer Brown, Shelby Royal, Nick Burgmeier, Rod Williams

FNR Annual Poster Competition

Globally, greater than half of amphibian species have suffered significant population declines and are now listed as threatened or endangered. Captive rearing has become a powerful management tool to address dwindling population numbers. While captive rearing has been used effectively for a small subset of species recovery programs for decades, captive rearing remains in its infancy for other species, like the Eastern Hellbender (Cryptobranchus alleganiensis alleganiensis). To this end, much remains unknown regarding critical components ofex situ approaches for this declining species. We are conducting a seven-month study to assess the impact captive densities have on Eastern Hellbender growth rates. …

Department of Agricultural Economics Faculty Publications

Can countries reorient their productive capacity to become more environmentally friendly and inclusive? To investigate this question this paper uses a standard Input-Output modeling framework and data from 141 countries and regions to construct a new global dataset of employment, value-added, greenhouse gas (GHG) emissions (disaggregated into CO2 and Non-CO2 elements), and air pollution (including nine categories of air pollutants such as PM2.5) multipliers from supply side investments. We find that many of the traditional sectors in agriculture and industry have large employment multipliers, but also generate male dominant, lower skill employment, and tend to have higher emission multipliers. It …
