The Link Between Marine Thermal Discharges And Nemopilema Nomurai Blooms Around Nuclear Power Plants, Jiawei Wu, Jie Kong, Edward A. Laws, Xin Liu, Changyun Wang, Jixin Chen, Mianrun Chen, Qingzhen Yao, Yantao Wang, Yu Zhen, Chaolun Li, Bangqin Huang

Faculty Publications

Recent research has shown that jellyfish blooms occur more frequently near nuclear power plants (NPPs), and a relationship between thermal discharges from the NPPs and the blooms has been hypothesized. There is, however, no direct evidence that links the thermal discharges with jellyfish blooms. In this study, we conducted 3 cruises (pre-bloom, bloom, and post-bloom) during July to September 2017 in the area surrounding the largest NPP in northern China. The water temperature near the cooling water outfall rose by 2 °C. Although we found no significant impact on phytoplankton abundance or community composition near the outfall, a broader analysis …

Parental Engagement And Implementation Fidelity In A Mhealth Motor Skills Intervention For Young Children, Amanda E. Staiano, Sanjoy Saha, Robbie A. Beyl, Chelsea L. Kracht, Robert L. Newton, E. Kipling Webster

Population and Public Health Science Faculty Publications

Introduction: Mobile apps (i.e. mHealth) provide unprecedented opportunity for widespread dissemination of health behavior programs. However, for programs directed towards young children, parental engagement may explain differing results of mHealth programs. Within the context of an app-based fundamental motor skill (FMS) intervention that improved children’s motor skills (PLAY), this paper examines parents’ fidelity to the intervention and the extent to which fidelity was related to children’s motor skill improvements. Methods: In the PLAY trial, 72 children aged 3–5 years were randomized for their parents to access a Motor Skills app or Free Play app for a 12-week intervention. The Motor …

Population and Public Health Science Faculty Publications

Introduction: Remotely delivered treatment and research procedures were rapidly adopted in response to the COVID-19 pandemic. However, it is unclear if these measures are valid. The purpose of this study was to compare the validity of anthropometry and motor skill proficiency measurements collected in a remote-setting to in-person setting among a sample of children ages 3–4 years. Methods: Child anthropometry and motor skill performance were measured in-person by trained assessors and by parents at home with remote supervision via videoconference by trained assessors. The following measures from the National Institutes of Health Toolbox were collected: anthropometry (height and weight), manual …

Key Parameters Linking Cyber-Physical Trust Anchors With Embedded Internet Of Things Systems, Michele Maasberg, Leslie G. Butler, Ian Taylor

Faculty Publications

Integration of the Internet of Things (IoT) in the automotive industry has brought benefits as well as security challenges. Significant benefits include enhanced passenger safety and more comprehensive vehicle performance diagnostics. However, current onboard and remote vehicle diagnostics do not include the ability to detect counterfeit parts. A method is needed to verify authentic parts along the automotive supply chain from manufacture through installation and to coordinate part authentication with a secure database. In this study, we develop an architecture for anti-counterfeiting in automotive supply chains. The core of the architecture consists of a cyber-physical trust anchor and authentication mechanisms …

Faculty Publications

Hot sauces are popular peppery condiments used to add flavor and sensory excitement to gastronomical preparations. While hot sauce occupies a retail category well over a century old, a novel production method using liquor as the base preservative rather than traditional vinegar is now commercially available, and its uniqueness begs study. Hot sauces produced with tequila, rum, vodka, and bourbon were compared to traditional vinegar-based hot sauces concerning physicochemical properties, volatile compounds, microbiological quality, sensory scores, emotions, and purchase intent (PI). Under accelerated conditions, pH, titratable acidity (TA), water activity (Aw), viscosity, and color were analyzed weekly for 20 weeks, …

The Rise Of Native Lordships At Pashash, A.D. 200–600, North Highlands Of Ancash, Peru, George F. Lau, Milton Luján Dávila, Jacob L. Bongers, David Chicoine

Faculty Publications

This article examines the rise of native, segmentary lordships in the highlands of north-central Peru. It reports on new excavations and mapping at the seat of a prehispanic polity, Pashash (Recuay culture), a large hilltop center that developed after the collapse of Chavín civilization. Fieldwork revealed monumental constructions and two special activity contexts radiocarbon-dated to ca. a.d. 200–400: an offering area in a large palatial compound and a room-complex with chambers closed off and sealed with feasting refuse. Multiple lines of evidence help reconstruct a regional picture for the establishment of wealthy local elites. Cultural innovations explicitly link new leaders …

A Cyclically Adjusted Spatio-Temporal Kernel Density Estimation Method For Predictive Crime Hotspot Analysis, Ya Han, Yujie Hu, Haojie Zhu, Fahui Wang

Faculty Publications

This paper presents a new method for predictive crime hotspot analysis that further improves the kernel density estimation (KDE) method and the spatio-temporal kernel density estimation (STKDE) method by accounting for temporal crime cycles and is therefore termed the ‘cyclically adjusted STKDE (cSTKDE) method’. The case study on robbery incidents in Baton Rouge, Louisiana, shows a temporal cycle with a 6-month period of statistical significance from January 2010 to May 2018. This identified period is incorporated into the temporal kernel function of the new cSTKDE method. For validation, the Forecast Accuracy Index (FAI) and Forecast Precision Index (FPI) are used …

Between Black Mothers And Daughters: A Critical Intergenerational Duoethnography On The Silence Of Health Disparities And Hope Of Loud Healing, Asha S. Winfield, Hope Hickerson, Deshara C. Doub, Ann R. Winfield, Brigitte Mcphatter

Faculty Publications

Introduction: Black American women's health outcomes have been altered by a number of factors. Those factors include social determinants of health, lack of culturally competent healthcare providers, and generations of medical racism leading to prolonged pain, delayed care, and sometimes, untimely deaths. Methods: This original research article centers Southern Black women's lived experiences through family storytelling. We explored generations of health narratives in regard to age, region, and at times, their own acts of silence. Building from theorizing on loud healing, two Black daughters turned the mic on for their mothers by engaging in a critical intergenerational double duoethnography to …

Prep On Tiktok: Benefits, Barriers, And Possibilities, Joseph Schwartz, Josh Grimm, Cameron Jamison

Faculty Publications

HIV remains a serious problem in the U.S. particularly for men who have sex with men. PrEP is an intervention that can dramatically decrease the risk of HIV infection. Because rates of PrEP adoption have been lower than anticipated, researchers have called for new tactics for promoting PrEP. For this reason, we analyzed PrEP messaging on TikTok. In an analysis guided by the Health Belief Model, we found that discussions of PrEP benefits and barriers were most common on TikTok. Severity and susceptibility were least common. We distilled these findings into suggestions for promoting PrEP adoption.

Study On Soft Robotic Pinniped Locomotion, Dimuthu D.K. Arachchige, Tanmay Varshney, Umer Huzaifa, Iyad Kanj, Thrishantha Nanayakkara, Yue Chen, Hunter B. Gilbert, Isuru S. Godage

Faculty Publications

Legged locomotion is a highly promising but under-researched subfield within the field of soft robotics. The compliant limbs of soft-limbed robots offer numerous benefits, including the ability to regulate impacts, tolerate falls, and navigate through tight spaces. These robots have the potential to be used for various applications, such as search and rescue, inspection, surveillance, and more. The state-of-the-art still faces many challenges, including limited degrees of freedom, a lack of diversity in gait trajectories, insufficient limb dexterity, and limited payload capabilities. To address these challenges, we develop a modular soft-limbed robot that can mimic the locomotion of pinnipeds. By …

Dynamic Modeling And Validation Of Soft Robotic Snake Locomotion, Dimuthu D.K. Arachchige, Sanjaya Mallikarachchi, Iyad Kanj, Dulanjana M. Perera, Yue Chen, Hunter B. Gilbert, Isuru S. Godage

Faculty Publications

Soft robotic snakes made of compliant materials can continuously deform their bodies and, therefore, mimic the biological snakes' flexible and agile locomotion gaits better than their rigid-bodied counterparts. Without wheel support, to date, soft robotic snakes are limited to emulating planar locomotion gaits, which are derived via kinematic modeling and tested on robotic prototypes. Given that the snake locomotion results from the reaction forces due to the distributed contact between their skin and the ground, it is essential to investigate the locomotion gaits through efficient dynamic models capable of accommodating distributed contact forces. We present a complete spatial dynamic model …

Kadonsky, Kyle Bibby, Aaron Bivins, Gertjan Medema, Warish Ahmed, Panagis Katsivelis, Vajra Allan, Ryan Sinclair, Joan B. Rose

Faculty Publications

A year since the declaration of the global coronavirus disease 2019 (COVID-19) pandemic, there were over 110 million cases and 2.5 million deaths. Learning from methods to track community spread of other viruses such as poliovirus, environmental virologists and those in the wastewater-based epidemiology (WBE) field quickly adapted their existing methods to detect SARS-CoV-2 RNA in wastewater. Unlike COVID-19 case and mortality data, there was not a global dashboard to track wastewater monitoring of SARS-CoV-2 RNA worldwide. This study provides a 1-year review of the “COVIDPoops19” global dashboard of universities, sites, and countries monitoring SARS-CoV-2 RNA in wastewater. Methods to …

Simulating Stellar Merger Using Hpx/Kokkos On A64fx On Supercomputer Fugaku, Patrick Diehl, Gregor Dais, Kevin Huck, Dominic Marcello, Sagiv Shiber, Hartmut Kaiser, Dirk Pfluger

Faculty Publications

The increasing availability of machines relying on non-GPU architectures, such as ARM A64FX in high-performance computing, provides a set of interesting challenges to application developers. In addition to requiring code portability across different parallelization schemes, programs targeting these architectures have to be highly adaptable in terms of compute kernel sizes to accommodate different execution characteristics for various heterogeneous workloads. In this paper, we demonstrate an approach to code and performance portability that is based entirely on established standards in the industry. In addition to applying Kokkos as an abstraction over the execution of compute kernels on different heterogeneous execution environments, …

Faculty Publications

This paper develops a social media-disaster resilience analysis framework by categorizing types of social media use and their challenges to better understand and assess its role in disaster resilience research and management. The framework is derived primarily from several case studies of Twitter use in three hurricane events in the United States–Hurricanes Isaac, Sandy, and Harvey. The paper first outlines four major contributions of social media data for disaster resilience research and management, which include serving as an effective communication platform, providing ground truth information for emergency response and rescue operations, providing information on people’s sentiments, and allowing predictive modeling. …

Achieving Online And Scalable Information Integrity By Harnessing Social Spam Correlations, Hailu Xu, Pinchao Liu, Boyuan Guan, Qingyang Wang, Dilma Da Silva, Liting Hu

Faculty Publications

Malicious web links, social rumors, fraudulent advertisements, faked comments, and biased propaganda are overwhelmingly influencing online social networks. Enabling information integrity is a hot topic in both academia and industry. Traditional social spam detection techniques rely on centralized processing, focusing only on one specific set of data sources, thereby ignoring the social spam correlations between distributed data sources. In this paper, we propose an online and scalable misinformation detection system, named Spiral, to uncover social spam by leveraging the correlations between different social data sources in geo-distributed sites. The key insight in our approach is to amplify the effectiveness of …

Freeboard Life-Cycle Benefit-Cost Analysis Of A Rental Single-Family Residence For Landlord, Tenant, And Insurer, Ehab Gnan, Rubayet Bin Mostafiz, Md Adilur Rahim, Carol J. Friedland, Robert V. Rohli, Arash Taghinezhad, Ayat Al Assi

Faculty Publications

Flood risk to single-family rental housing remains poorly understood, leaving a large and increasing population underinformed to protect themselves, including regarding insurance. This research introduces a life-cycle benefit-cost analysis for the landlord, tenant, and insurer [i.e., (U.S.) National Flood Insurance Program (NFIP)] to optimize freeboard [i.e., additional first-floor height above the base flood elevation (BFE)] selection for a rental single-family home. Flood insurance premium; apportioned flood risk among the landlord, tenant, and NFIP by insurance coverage and deductible; rental loss; moving and displacement costs; freeboard construction cost; and rent increase upon freeboard implementation are considered in estimating net benefit (NB) …

Feasible Delivery System Based On Poly(Lactictide-Co-Glycolide) Nanoparticles Loaded With Antimicrobial Mupirocin For Possible Wound Healing, Ludmila Košarišťanová, Tomáš Komprda, Vendula Popelková, Tatiana Fialová, Pavla Vymazalová, Carlos E. Astete

Faculty Publications

The objective of the study was to assess cytotoxicity (based on the dimethylthiazol– diphenyltetrazolium bromide cell viability assay) and antimicrobial effects of poly(lactictide-co-glycolide) nanoparticles with entrapped mupirocin (PLGA/MUP NPs) on Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) strains using a disk-diffusion method, cryo-scanning electron microscopy (cryo-SEM) and fluorescence microscopy. Based on the evaluation of the growth curve, PLGA/MUP NPs inhibited growth of the both tested strains already at a concentration of 0.29 µg/ml, and their inhibitory effect at concentrations from 0.29 to 1.17 µg/ml was comparable with free MUP using the disk-diffusion method. PLGA/MUP NPs also tended to increase the …

Resonant Perfect Absorption Yielded By Zero-Area Pulses, Yu He, Zuoye Liu, Christian Ott, Adrian N. Pfeiffer, Shaohua Sun, Mette B. Gaarde, Thomas Pfeifer, Bitao Hu

Faculty Publications

We propose and study the manipulation of the macroscopic transient absorption of an ensemble of open two-level systems via temporal engineering. The key idea is to impose an ultrashort temporal gate on the polarization decay of the system by transient absorption spectroscopy, thus confining its free evolution and the natural reshaping of the excitation pulse. The numerical and analytical results demonstrate that even at moderate optical depths, the resonant absorption of light can be reduced or significantly enhanced by more than 5 orders of magnitude relative to that without laser manipulation. The achievement of the quasicomplete extinction of light at …

Genetic Characterization Of Resitance To Frogeye Leaf Spot Of Soybean, Gabriel D. Munoz Herrera

LSU Master's Theses

Cercospora sojina is the causal agent of the fungal disease frogeye leaf spot (FLS) in soybeans. Management of this disease consists of foliar application of fungicides and the use of resistant cultivars. However, fungicide resistance has been detected in C. sojina populations and characterization of host resistance genes is relatively limited. To overcome the latter obstacle, we aimed to identify novel resistance genes using quantitative image analysis of the SoyNAM population. Two image analysis workflows using ImageJ and PlantCV were optimized and implemented to increase reproducibility and reduce subjectivity. The quantitative measurements included disease severity, lesion count, and average lesion …

From Mapping Place To Mapping Space In Library Gis Work, Lena Denis

Journal of Critical Digital Librarianship

At many academic libraries, library workers run the teaching, general reference consultations, technical troubleshooting, and software and licensing maintenance in Geographic Information Systems (GIS) for their institutions. This is very much the case in the Data Services unit of Johns Hopkins University’s Sheridan Libraries, where staff receive requests for help with a wide variety of mapping projects every semester. Sometimes they are straightforward requests for technical assistance, but sometimes they underpin much deeper investigations into how to situate people and significant events through time and geographic settings. This article discusses these types of requests in the context of the philosophical …

Leveraging Critical Information Literacy To Develop Social Justice-Minded Data Literacy Competencies, Ben B. Chiewphasa, Matthew L. Sisk

Journal of Critical Digital Librarianship

Librarians who interact with data in different contexts can come together in a community of practice – leveraging each other's perspectives to collectively engage with critical librarianship and reimagine social justice-related learning outcomes for information and data literacy programming. Specifically, this paper explores the overlapping goals of different critical literacies (such as critical information literacy and QuantCrit), showcasing that synergies exist between social justice-oriented librarians with distinctive roles and responsibilities. By leveraging a community of practice as a vehicle for continuing education in inclusive pedagogy, librarians can empower their patrons, students, and colleagues to challenge and act upon surrounding data …

Low total energy expenditure (TEE, MJ/d) has been a hypothesized risk factor for weight gain, but repeatability of TEE, a critical variable in longitudinal studies of energy balance, is understudied. We examine repeated doubly labeled water (DLW) measurements of TEE in 348 adults and 47 children from the IAEA DLW Database (mean ± SD time interval: 1.9 ± 2.9 y) to assess repeatability of TEE, and to examine if TEE adjusted for age, sex, fat-free mass, and fat mass is associated with changes in weight or body composition. Here, we report that repeatability of TEE is high for adults, but …
