Efficient Privacy-Preserving Conjunctive Searchable Encryption For Cloud-Iot Healthcare Systems, Jiadi Ma, Tianqi Peng, Gong Bei, Muhammad Waqas, Hisham Alasmary, Sheng Chen

Research outputs 2022 to 2026

In cloud-Internet of Things (IoT) healthcare systems, private medical data leakage is a serious concern as the cloud server is not fully trusted. Dynamic searchable symmetric encryption (DSSE), with necessary forward and backward privacy security properties, enables doctors to retrieve ciphertexts while guaranteeing data privacy. However, existing forward and backward private DSSE schemes are not well-suited for cloud-IoT healthcare systems with attribute-value type databases. To this end, we propose an efficient privacy-preserving conjunctive searchable encryption scheme for cloud-IoT healthcare systems, called PC-SE. It is the first conjunctive DSSE scheme designed for attribute-value type databases. Specifically, we design flexible search capabilities …

This review synthesizes recent research on the utilization of major mining waste streams, with particular emphasis on pavement applications and other construction materials. The findings indicate that bauxite residue exhibits both pozzolanic and filler characteristics, demonstrating potential in asphalt mastics, asphalt mixtures, and other construction products. Nonetheless, its widespread adoption is constrained by issues such …

Taurine Supplementation And Human Heat Tolerance: Mechanisms, Evidence, And Integration With Heat Acclimation, Cooling, And Hydration, Siavash Naddafha, Jeffrey R. Stout, Cassandra Evans

Research outputs 2022 to 2026

Heat exposure during strenuous exercise increases core temperature and cardiovascular strain, impairing performance and elevating the risk of heat illness. Standard countermeasures include heat acclimation, cooling, and hydration/electrolyte planning. Taurine is a sulfur-containing amino acid present in excitable tissues and widely used as an oral supplement; emerging human trials suggest it can augment thermoregulation, primarily by enhancing eccrine sweating and evaporative heat loss. This narrative review synthesizes mechanistic and applied evidence on taurine during exercise in hot environments and evaluates potential interactions with acclimation, cooling strategies (pre- and per-cooling), and hydration practices. Across a small number of randomized, mostly double-blind …

Identification Of Affinity-Optimized Peptide Binders Of A Viral Protease For Chemical Genetic Applications, Glenna W Foight, Douglas M Fowler, Dustin J Maly

Faculty, Staff and Students Publications

Chemically-controlled genetic tools are useful for studying biological systems due to their ability to dose-dependently and temporally modulate intracellular function. Chemically-disrupted proximity (CDP) systems, which involve the pre-localization of two interacting protein components that can be disrupted with a small molecule, are complementary to more commonly used chemically-inducible dimerization (CID) systems. However, fewer CDP systems have been developed, and the genetically-encoded protein components have not been as optimized for intracellular applications. Here, we describe a transcriptional activation reporter assay for screening the intracellular interaction between the 21-amino acid peptide ANR and HCVp NS3a, which are the genetically-encoded components of a …

Background: Respiratory viral infections are common and can trigger asthma exacerbations in children. The roles of the nasal microbiome and phageome (viruses that infect microbes) are not well understood.

Objective: We sought to characterize the epidemiology of respiratory viral infections and the interplay between the nasal microbiome, phageome, and viral infections in school-age children with asthma.

Methods: We performed metagenomic sequencing and quantitative RT-PCR detection of respiratory viruses on 375 nasal samples from 227 school-age children with asthma collected routinely 3 times over a year. Surveys on parent-reported cold and asthma symptoms were administered routinely every 2 months. We evaluated …

On Resolving The Neutron Lifetime Puzzle, Polievkt Perov

College of Arts & Sciences Faculty Works

The neutron lifetime puzzle, characterized by significantly different lifetime values obtained from bottle vs beam experiments, may stem from differences in how decayed neutrons are counted. Neutron decay is a beta-decay process producing a proton, an electron, and a neutrino. In bottle experiments, the number of decayed neutrons is measured directly. In beam experiments, this number is inferred indirectly by counting the protons resulting from neutron decays. It is proposed that in beam experiments, some protons may capture electrons and form neutral hydrogen atoms, which go undetected by proton detectors. Consequently, not all neutron decay events are counted, leading to …

Dolichocolon Is Common In Pediatric Gastroenterology Patients With Constipation And Associated Complaints, Arvind Mohan, Partha Chakraborty, Timot Kellermayer, Eric H Chiou, Craig L Jensen, Ricardo A Arbizu, Marla B K Sammer, Richard Kellermayer

Faculty, Staff and Students Publications

Objectives: Dolichocolon (DC), classified under International Classification of Diseases, Tenth Revision (ICD-10) code Q43.8 ("Other specified congenital malformations of intestine"), refers to an elongated or redundant large intestine. Recent studies in adults indicate a role for dolichocolon in constipation and disorders of gut-brain interaction. Contrast enema (CE) imaging is commonly used to identify DC, typically defined as a sigmoid colon extending above, or a transverse colon descending below, the iliac crest line. Despite its potential relevance, the prevalence and clinical significance of DC in pediatric gastroenterology remain poorly understood.

Methods: This retrospective study assessed the prevalence of DC in pediatric …

Leader Rounding For Outcomes To Improve Employee Retention, Laura R. Escobar

Electronic Theses and Dissertations

Intention to leave a nursing staff position, if not addressed, may lead to an increased rate of nursing turnover. High turnover rates can negatively affect staffing patterns, increase organizational costs, and disrupt the continuity of patient care. A quantitative quasi-experimental pre-/posttest design was used to evaluate the impact of the High Reliability Organization Leader Rounding for Outcomes tool to reduce the intent-to-leave scores, as measured by the Turnover Intention Scale (TIS-6), compared to current practice over 12 weeks. Implementation of the tool provided a structured leader rounding process designed to strengthen communication, recognize staff contributions, and proactively identify workplace concerns. …

Longevity, Resilience, And Thriving Of Women In Ministry: A Case Study Of Women In Ministry From A United Pentecostal Holiness Church, Eunice Cheryl Feltus Little

Electronic Theses and Dissertations

Abstract

The problem of ministry attrition caused by burnout is well documented. Research attributes the impact of burnout on the resilience, longevity, and thriving of ministry workers to role-related stress and adversity. High attrition rates throughout religious organizations and a lag in longevity and resilience contribute to a shortage of ministry workers. Some ministry workers leave the vocation because of stress and burnout, yet others persevere. Despite the possible adverse effects, many men and women find a sense of well-being and joy in ministry work. This qualitative distributive case study focused on those who stayed in ministry and the strategies …

An emerging paradigm in public health focuses on enhancing nutrition in existing food staples to reduce chronic disease at the population scale, rather than relying on individuals to change their behavior. This paradigm leverages plant and animal breeding, production practices, and processing to enhance nutrition, whereby foods consumed by millions can be improved at low incremental cost. This article supports and operationalizes this paradigm, illustrating the potential to improve diets through a case study that increases the arabinoxylan fiber content of commodity wheat through classical plant breeding (a non-GMO technology). The approach described in this article proposes to link agricultural …

The Military’S Abortion Crisis In The Aftermath Of Dobbs V. Jackson Women’S Health Organization, Hugh Barrett Mcclean

All Faculty Scholarship

Women in the military have not had access to abortion care since 1978, when Congress introduced an amendment to a Department of Defense (DoD) appropriations bill, later codified under 10 U.S.C. § 1093, that prohibited the use of DoD funds for abortions. While women have endured this second-class health care for over four decades, the Supreme Court’s decision in Dobbs v. Jackson Women’s Health Organization has created new problems for servicewomen and the military writ large. Now military women must travel off-base and, in some instances, out-of-state or out-of-country, to seek an abortion. While women in and out of uniform …

“Oh! It’S Fine, We’Re Not Even Counting This Anyways”: Remote Educational Experiences Of Rural Families With A Child With A Disability During The Early Covid-19 Pandemic, Andrew M. Colombo-Dougovito, A. Josephine Blagrave, Aubrey Newland

The Rural Educator

Disparities in rural areas regarding technology, internet access, and higher teacher turnover were amplified as a plurality of schools across the US moved to remote instruction in early 2020 as a response to the COVID-19 pandemic. While rural communities often show a greater resiliency and resourcefulness in the face of tragedy than their (typically) more affluent suburban or urban neighbors, regardless of location, the needs of children receiving educational accommodations are often not met effectively or are ignored altogether. To understand if those educational needs were met for rural families early in the COVID-19 pandemic, an exploratory descriptive qualitative approach …

Challenges To Equity Leadership: Rural Leadership For Marginalized Students, Alex N. Oldham

The Rural Educator

This study examines the challenges and importance of equity-oriented leadership in rural schools. Equity, as opposed to equality, involves providing all students with the resources and support they need to succeed. Research indicates that equity-oriented leadership is crucial for creating positive school climates and improving student outcomes. However, implementing equity-oriented leadership in rural schools can be particularly challenging due to contextual factors and potential resistance from communities with differing values. The study explores the challenges and benefits of equity-oriented leadership in rural schools. While some principals express a desire to lead equitably and implement various initiatives to promote positive outcomes …

From Classroom To Field: Rural Teachers’ Integration Of Science And The Outdoors, Steph N. Dean, Julianne A. Wenner

The Rural Educator

This study explored how rural educators in the US use outdoor environments to enhance science instruction, addressing the educational marginalization of rural students. Using rural cultural wealth as a theoretical framework, we investigated how rural teachers integrate local nature-based resources and students’ out-of-school experiences into science learning. We conducted interviews and observations with rural teachers, using reflexive thematic analysis as our qualitative approach. Three key themes emerged that highlight the ways our participants use the outdoor environment to teach science: (a) harness rural community partnerships, (b) engage students through relational teaching, and (c) design learning opportunities that honor students as …

Impacts Of Literacy Programming During The Covid-19 And Recovery School Years, Julie Meredith

The Rural Educator

While numerous articles and research reports have focused on understanding the impact of COVID-19 recovery interventions on students in urban and rural schools, fewer have addressed the impact of school closures and efforts to recover lost learning time on children in rural schools. Children in rural areas faced challenges similar to their peers in urban and suburban areas, but infrastructure challenges in many rural places, such as lack of broadband, required tailored approaches guided by educators’ knowledge and connection to their communities. This article examines the impact of Save the Children’s school-age literacy program, supported by 21st Century Community Learning …

One-Step Purification Of A Bioactive Pak1-Derived Peptide, Djamali Muhoza, Emily P. Esquivel, Stacy R. Hunter, Pateince S. Okoto, Thallapuranam K.S. Kumar, Paul D. Adams

Chemistry & Biochemistry Faculty Publications and Presentations

The serine/threonine kinase PAK1 serves as a mediator of cytoskeletal reorganization and cancer-related signaling downstream of the small GTPases. Due to the challenges in purifying PAK1 complexes, a 46-residue peptide from PAK1, is widely used to study PAK1-Cdc42 signaling. Traditionally, this purification involved multi-step chromatography of recombinant GST-PBD46 complexes, yielding approximately 1 mg per 1.5 L culture. In this study, a 30 min heat treatment step after thrombin cleavage was used to precipitate GST while leaving pure PBD46 in solution. This step eliminated the need for further affinity and size-exclusion chromatography steps. This improved protocol produces proteins with a 6.5-fold …

A Citizenship Model Of The Fourth Amendment, Danieli Evans

Articles

Fourth Amendment law is in disarray. In recent years, courts and scholars have questioned central aspects of Fourth Amendment doctrine—in particular, the reasonable expectations of privacy test that has governed since the 1960s. Scholars and judges have argued for abandoning this test and instead looking to private law (sub-constitutional rules governing private conduct, such as tort, property, and contract law) to determine Fourth Amendment protection.

At a moment when judges and scholars are questioning core aspects of Fourth Amendment doctrine, the time is ripe to reconsider the values Fourth Amendment law ought to serve. I advance a novel vision for …

Reinforced Scan: A Reinforcement Learning Enabled Optimal Laser Scan Path Planning In Laser Powder Bed Fusion Additive Manufacturing, Chaoran Dou, Jihoon Chung, Raghav Gnanasambandam, Yuhao Wu, Jianzhi Li, Zhenyu James Kong

Manufacturing & Industrial Engineering Faculty Publications

Additive Manufacturing is an innovative technology that fabricates parts layer by layer. However, in Laser Powder Bed Fusion (LPBF), printed metal parts often exhibit residual stresses, deformations, and other defects due to non-uniform temperature distribution during the printing process. To mitigate these issues, an optimized scan sequence within each layer can improve thermal uniformity. Traditional optimization methods, which rely on domain knowledge and employ trial-and-error or heuristic approaches, often fail to achieve optimal solutions due to the complex nature of the problem. One major challenge in improving scan strategies lies in the vast search space required to optimize the scan …

Dissertations, Theses, and Capstone Projects

This dissertation examines predictive risk modelling (PRM) in New York City Administration for Children's Services (ACS), specifically exploring AI-enabled design features, practices, and encoded and racialized assumptions about risk in child welfare prevention services. Guided by Critical Race Theory and the Algorithmic Ecology framework, this study traces how PRM in ACS evolved from a service termination tool into a broader, largely internal surveillance apparatus that leverages families’ personal information, including health information, to assess risk of future maltreatment and to evaluate contracted service providers. Drawing on analysis of public records and in-depth interviews with Black parents, the findings describe how …

Voices Of Agency: Unpacking Student Insights On Nysed Content Standards, Local Curricular Practices, Pedagogy In New York State Schools, And Their Educational Implications, Alprentice Ashanti Talibudeen Mccutchen

Dissertations, Theses, and Capstone Projects

This research sets out to explore the concept of agency in the context of education, including my distinction between passive agency and active agency, and how these distinctions have been taken up by scholars, educators, and policy makers. The core approach is based in an expansive inclusion of various perspectives on agency as a basis for developing a comprehensive framework of active agency as well as its opportunities for educational practices and outcomes. I am arguing that there is a gap—an agency gap—between the passive and active employment of agency. I am also arguing that there is an agency in …
