Downstream Effects: Impact Of Antibiotic Pollution On An Aquatic Host-Parasite Interaction, Hannah G. Melchiorre, Stephanie O. Gutierrez, Dennis J. Minchella, Jing Trevor Vannatta

Purdue University Libraries Open Access Publishing Fund

The global increase in antibiotic use has led to contamination of freshwater environments. Despite the identified impacts of antibiotics on humans and wildlife, the effect of antibiotics on host–parasite life cycles in freshwater is relatively unexplored. In the current study, we utilize the trematode parasite Schistosoma mansoni, and its snail intermediate host, Biomphalaria glabrata, to investigate the influence of an ecologically relevant antibiotic concentration on the life history characteristics of both parasite and host. Our results demonstrate that antibiotics not only accelerate parasite development time, but also increase host reproduction and delay parasite-induced host castration. Using a mathematical …

Coronal Mass Ejections, Alex Echeverria May 2023

Coronal Mass Ejections, Alex Echeverria

American Journal of Rising Scholar Activities

The underlying dynamics of solar processes are a topic of considerable interest, because the events on the surface of the Sun directly affect the environment of our planet. Certain ‘storms’ that erupt in the outer layers of the Sun can propel masses of electrically charged plasma into the solar system. If the path of that material crosses Earth’s orbit, it can disrupt our societal electronic and satellite resources. Observing and analyzing these events is a first step toward predicting them and hardening our equipment against them. This work reviews how solar scientists collect and view this data on coronal mass …

U-No: U-Shaped Neural Operators, Md Ashiqur Rahman, Zachary E Ross, Kamyar Azizzadenesheli May 2023

U-No: U-Shaped Neural Operators, Md Ashiqur Rahman, Zachary E Ross, Kamyar Azizzadenesheli

Department of Computer Science Faculty Publications

Neural operators generalize classical neural networks to maps between infinite-dimensional spaces, e.g., function spaces. Prior works on neural operators proposed a series of novel methods to learn such maps and demonstrated unprecedented success in learning solution operators of partial differential equations. Due to their close proximity to fully connected architectures, these models mainly suffer from high memory usage and are generally limited to shallow deep learning models. In this paper, we propose U-shaped Neural Operator (U-NO), a U-shaped memory enhanced architecture that allows for deeper neural operators. U-NOs exploit the problem structures in function predictions and demonstrate fast training, data …

Study Of The Impact Of Boundary Conditions On Acoustical Behavior Of Granular Materials And Their Implementation In The Finite Difference Method, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton May 2023

Study Of The Impact Of Boundary Conditions On Acoustical Behavior Of Granular Materials And Their Implementation In The Finite Difference Method, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

Granular materials display significant differences in their acoustical response when tested in a standing wave tube, compared with the behavior of more traditional sound absorbing materials such as fibrous webs and foams. The latter materials can often be modeled as an equivalent fluid with the further assumption that the material properties do not depend on the input signal level. In contrast, the level dependence of the acoustical behavior of granular materials has been observed in measurements of glass bubbles, as reported in previous studies, for example. When the input level is low, the absorption coefficient of the glass bubble stack …

Prediction Of Acoustical Behavior Of Granular Material Stacks As Measured In A Standing Wave Tube By Using A Biot Theory-Based Model, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton May 2023

Prediction Of Acoustical Behavior Of Granular Material Stacks As Measured In A Standing Wave Tube By Using A Biot Theory-Based Model, Zhuang Mo, Guochenhao Song, Tongyang Shi, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

The acoustical behavior of granular materials, such as activated carbon and silica gel, has drawn attention in recent studies, due to their favorable properties such as good low frequency sound absorption. Like other more traditional porous materials, granular materials can also be tested in a standing wave tube for a convenient assessment of their acoustical properties. However, the behavior of granular materials stacked in a standing tube is more complex than that of traditional materials. For example, the response of lightweight glass bubbles reveals a clear dependence on the sound pressure level of the input signal. Also, when tested in …

Design And Optimization Of Lightweight Porous Damping Treatments, Yutong Xue, J Stuart Bolton May 2023

Design And Optimization Of Lightweight Porous Damping Treatments, Yutong Xue, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

Here, it is shown that properly-designed limp porous materials such as fibrous layers can provide damping equivalent to conventional viscoelastic dampers while providing advantages such as light weight and effective sound absorption. This then allows porous layers to be used as multi-functional noise and vibration control solutions in automotive and aerospace applications. It has also been found that the addition of bulk elasticity to the solid phase of the porous medium is beneficial since it improves damping performance compared to equivalent limp treatments. In this study, porous media, such as fibers and foams, were designed to serve as treatments for …

Global-To-Local-To-Global Interactions And Climate Change, Uris Baldos, Maksym Chepeliev, Brian Cultice, Matthew Huber, Sisi Meng, Alex C. Ruane, Shellye Suttles, Dominique Van Der Mensbrugghe Apr 2023

Global-To-Local-To-Global Interactions And Climate Change, Uris Baldos, Maksym Chepeliev, Brian Cultice, Matthew Huber, Sisi Meng, Alex C. Ruane, Shellye Suttles, Dominique Van Der Mensbrugghe

Department of Agricultural Economics Faculty Publications

Climate change by its very nature epitomizes the necessity and usefulness of the global-to-local-to-global (GLG) paradigm. It is a global problem with the potential to affect local communities and ecosystems. Accumulation of local impacts and responses to climate change feeds back to regional and global systems creating feedback loops. Understanding these complex impacts and interactions is key to developing more resilient adaptation measures and designing more efficient mitigation policies. To this date, however, GLG interactions have not yet been an integrative part of the decision-support toolkit. The typical approach either traces the impacts of global action on the local level …

Method For Estimating Pulsatile Wall Shear Stress From One-Dimensional Velocity Waveforms, Joseph C. Muskat, Charles F. Babbs, Craig J. Goergen, Vitaliy L. Rayz Apr 2023

Method For Estimating Pulsatile Wall Shear Stress From One-Dimensional Velocity Waveforms, Joseph C. Muskat, Charles F. Babbs, Craig J. Goergen, Vitaliy L. Rayz

Purdue University Libraries Open Access Publishing Fund

Wall shear stress (WSS)—a key regulator of endothelial function—is commonly estimated in vivo using simplified mathematical models based on Poiseuille's flow, assuming a quasi-steady parabolic velocity distribution, despite evidence that more rapidly time-varying, pulsatile blood flow during each cardiac cycle modulates flow-mediated dilation (FMD) in large arteries of healthy subjects. More exact and accurate models based on the well-established Womersley solution for rapidly changing blood flow have not been adopted clinically, potentially because the Womersley solution relies on the local pressure gradient, which is difficult to measure non-invasively. We have developed an open-source method for automatic reconstruction of unsteady, Womersley-derived …

Mhealth Hyperspectral Learning For Instantaneous Spatiospectral Imaging Of Hemodynamics, Yuhyun Ji, Sang Mok Park, Semin Kwon, Jung Woo Leem, Vidhya Vijayakrishnan Nair, Yunjie Tong, Young L. Kim

Purdue University Libraries Open Access Publishing Fund

Hyperspectral imaging acquires data in both the spatial and frequency domains to offer abundant physical or biological information. However, conventional hyperspectral imaging has intrinsic limitations of bulky instruments, slow data acquisition rate, and spatiospectral trade-off. Here we introduce hyperspectral learning for snapshot hyperspectral imaging in which sampled hyperspectral data in a small subarea are incorporated into a learning algorithm to recover the hypercube. Hyperspectral learning exploits the idea that a photograph is more than merely a picture and contains detailed spectral information. A small sampling of hyperspectral data enables spectrally informed learning to recover a hypercube from a red–green–blue (RGB) …

Hybrid Statistical And Machine Learning Methods For Daily Evapotranspiration Modeling, Erdem Kucuktopcu Mar 2023

Hybrid Statistical And Machine Learning Methods For Daily Evapotranspiration Modeling, Erdem Kucuktopcu

Purdue University Libraries Open Access Publishing Fund

Machine learning (ML) models, including artificial neural networks (ANN), generalized neural regression networks (GRNN), and adaptive neuro-fuzzy interface systems (ANFIS), have received considerable attention for their ability to provide accurate predictions in various problem domains. However, these models may produce inconsistent results when solving linear problems. To overcome this limitation, this paper proposes hybridizations of ML and autoregressive integrated moving average (ARIMA) models to provide a more accurate and general forecasting model for evapotranspiration (ET0). The proposed models are developed and tested using daily ET0 data collected over 11 years (2010–2020) in the Samsun province of Türkiye. The results show …

Direct Van Der Waals Simulation (Dvs) Of Phase-Transforming Fluids, Tianyi Hu, Hao Wang, Hector Gomez Mar 2023

Direct Van Der Waals Simulation (Dvs) Of Phase-Transforming Fluids, Tianyi Hu, Hao Wang, Hector Gomez

Purdue University Libraries Open Access Publishing Fund

We present the method of direct van der Waals simulation (DVS) to study computationally flows with liquid-vapor phase transformations. Our approach is based on a discretization of the Navier-Stokes-Korteweg equations, which couple flow dynamics with van der Waals’ nonequilibrium thermodynamic theory of phase transformations, and opens an opportunity for first-principles simulation of a wide range of boiling and cavitating flows. The proposed algorithm enables unprecedented simulations of the Navier-Stokes-Korteweg equations involving cavitating flows at strongly under-critical conditions and ��(105) Reynolds number. The proposed technique provides a pathway for a fundamental understanding of phase-transforming flows with multiple applications in science, engineering, …

Recognition Of Design Failure By Fourth-Grade Students During An Engineering Design Challenge, Ron K. Skinner, Danielle B. Harlow

Journal of Pre-College Engineering Education Research (J-PEER)

The practice of persisting and learning from design failures is essential to engineering design and offers unique ways of knowing and learning for K-12 students. To understand how students engage in the practice of persisting and learning from design failures, we must first understand how, if at all, they recognize that a design failure has occurred. We studied a classroom of fourth-grade students engaged in an engineering design challenge and examined the ways in which design failure occurred and how students recognized, neglected to recognize, or misinterpreted design failure. We found that, in addition to anticipating failure, conducting fair tests, …

Terada Torahiko, A Physicist And A Haikai Poet, Akira Komiya Feb 2023

Terada Torahiko, A Physicist And A Haikai Poet, Akira Komiya

CLCWeb: Comparative Literature and Culture

Terada Torahiko is known as a scientific essayist in Japan, but hardly anyone knows he was a haikai poet as well as a physicist. According to him, haikai poetry and physics are two different ways of conceiving Nature, both valid and perhaps complementary to each other. Seeing his research in physics looking for regularities in apparently irregular phenomena in everyday life, we may say his haiku haikai spirit is manifest there and that he was pioneering a new science such as the one developed later by Ilya Prigogine. His association of haiku haikai poetry and Freudian interpretations of dreams leads …

Bergson On Poetics: Philosophy, Literature And Science, Michel Dalissier Feb 2023

Bergson On Poetics: Philosophy, Literature And Science, Michel Dalissier

CLCWeb: Comparative Literature and Culture

In this paper, I analyze Henri Bergson’s insightful and contrasted vision of poetry. First, I show in what sense Bergson sympathizes with the idea that the poet must be credited to surpass the novelist in offering to us an unparalleled emotional apprehension of the world. Second, I nonetheless underline how Bergson grants the product of the poet, i.e., the poem itself, a problematic linguistic status, inasmuch as the focus of his analysis shifts from an intersubjective poetical apprehension of feelings to their individual poetic appreciation, or from the spiritual dimension of poetry to its material dimension. Third, I further suggest …

The creativity of language Chomsky puts so much importance on must be questioned because the same creativity has produced lethal weapons such as atomic bombs. Modern science developed by the power of language has certainly produced many beneficial things, but we should not overlook its destructive side. Besides, language capable of inventing a new reality leads us to believe in it blindly. Let us remember philosophers such as Wittgenstein or Nagarjuna who warned us not to believe in the construct called “reality” made up by language power.Now, is it better and safer then to use a metaphorical language that composes …
