Center for Translational Medicine Faculty Papers

Objective: To compare the shaping ability of the XP-endo Shaper (XPS) system to the ProTaper Next (PTN) system in oval-shaped distal root canals.

Methods: From 12 mandibular molars, distal roots with moderately curved single oval canals were randomly assorted to be instrumented with XPS (experimental group) or PTN (control group) and then scanned using micro-computed tomography [Scan 1]. The root canals of the XPS samples were prepared following the manufacturer's instructions using 15 insertions (XPS15) and rescanned [Scan 2]. An additional 10 insertions to the working length were applied, totalling 25 insertions (XPS25), and the roots were rescanned again [Scan …

Exploration Of Dark Chemical Genomics Space Via Portal Learning: Applied To Targeting The Undruggable Genome And Covid-19 Anti-Infective Polypharmacology, Tian Cai, Li Xie, Muge Chen, Yang Liu, Di He, Shuo Zhang, Cameron Mura, Philip Boume, Lei Xie

Publications and Research

Advances in biomedicine are largely fueled by exploring uncharted territories of human biology. Machine learning can both enable and accelerate discovery, but faces a fundamental hurdle when applied to unseen data with distributions that differ from previously observed ones—a common dilemma in scientific inquiry. We have developed a new deep learning framework, called Portal Learning , to explore dark chemical and biological space. Three key, novel components of our approach include: (i) end-to-end, step-wise transfer learning, in recognition of biology’s sequence-structure-function paradigm, (ii) out-of-cluster meta-learning, and (iii) stress model selection. Portal Learning provides a practical solution to the out-of-distribution (OOD) …

Care And Compassion, Daisy Cuevas

Capstone Projects and Master's Theses

Many students who struggle with behavioral and mental health issues have a difficult time succeeding in school. Harden Middle School’s Wellness Center is where students struggling with socioemotional, mental, and behavioral health can come to receive support. The Care & Compassion program was created to address students who have more than five F’s or a zero-grade point average (GPA) and are failing classes at a high rate. A lack of parental and student engagement in distance learning, as well as depression due to isolation caused students to fall behind, fail classes and increased mental health concerns. Therefore, the Care & …

The Role Of The Serine/Threonine Phosphatase Pstp In The Mycobacterial Cell Wall Regulation, Farah Shamma

Biology Dissertations - Archive

Mycobacterium tuberculosis (Mtb) is the causative agent of the deadly infection Tuberculosis (TB). The current standard antibiotic regimen for TB treatment combines fours drugs to be taken for at least six months. Mtb shows intrinsic phenotypic tolerance to antibiotics contributing to the long treatment regimen. In addition, Mtb cells can achieve a non-replicating state exhibiting antibiotic tolerance, reduced metabolism and altered cell wall staining. The changes in the cell wall and reduced permeability to antibiotics in stressed cells suggest that the regulation of the cell wall is a major contributor to antibiotic tolerance. The mycobacterial cell wall consists of covalently …

Identification Of Resilience Dimensions And Development Of A Decision-Making System To Measure The Resilience Level Of Highway Networks, Thahomina Jahan Nipa

Civil Engineering Dissertations - Archive

Local as well as national economy and safety depend on the network characteristics of the transportation infrastructures. Destruction of transportation infrastructures causes the direct cost of the reconstruction as well as indirect cost due to loss of mobility. In addition, emergency response and recovery cannot be rendered if access to the affected community is hampered due to a damaged transportation network. Hence, researchers as well national and international organizations are focusing more on a resilience-based approach instead of a traditional recovery-based approach for the transportation infrastructures recently. As a result, there exist a high number of research articles that developed …

Evaluation Of Surface Asphalt Mixes Containing Recycled Asphalt Materials In North-East Texas Using Accelerated Pavement Testing, Ana Maria Coca

Civil Engineering Dissertations - Archive

Reclaimed asphalt pavement (RAP) and Reclaimed Asphalt Shingles (RAS) has proved to be an effective alternative to virgin materials in HMA production. Despite that recycling asphalt creates a cycle that optimizes the use of natural resources and sustains the pavement industry, State transportation departments have limited the maximum amount of RAP used in surface layers because of the variability concerns and lack of guidance provided. Even though at the moment, the United Stated recycles more RAP than Europe does in terms of percentage of the total RAP extracted from old pavements, it still lags Japan and other countries. A special …

Reuse Of Recycled Plastic For Plastic Road Design, Tahsina Islam

Civil Engineering Dissertations - Archive

The ever-increasing volume of traffic and the volatility of daily and seasonal temperatures that are being experienced globally make it essential that the quality and durability of roads are improved. Modifiers can improve the engineering properties of the asphalt mix in these situations. Perhaps plastics are the most promising of all types of modifiers. Since the disposal of plastic waste is a major concern for the environment, recycling of these waste materials is highly desired. The recycling and reuse of plastic waste is a prime example of sustainable waste management. It reduces the buildup of waste in landfills, thereby reducing …

Nebraska Department of Transportation: Research Reports

The purpose of this investigation was to determine the feasibility of measuring bituminous foundation course modulus under concrete roadways by comparing testing results derived before and after paving using FWD, Light Weight Deflectometer (LWD), and Dynamic Cone Penetrometer (DCP). The foundation course modulus was determined using FWD data and Darwin design software (‘93 AASHTO). Results from Phase I data collection, which occurred prior to pavement placement, provided a baseline for comparison. The maximum modulus was 398,000 PSI and the minimum was 85,000 PSI, yielding a range of 315,000 PSI and an average modulus of 123,000 PSI over the length of …

Best Practice Recommendation On Anesthesia Involvement In Preoperative Interdisciplinary Rounding On Surgical Inpatients, Elizabeth Davis

Doctoral Projects

Healthcare professionals are always seeking methods to improve patient care and patient outcomes and increase efficiency while reducing errors. By improving communication through the implementation of interdisciplinary communication, improved care quality, fewer variations in care, and enhanced collaboration among the healthcare team may be an outcome (Hoke & Falk, 2012). While anesthesia is involved in patient care throughout the perioperative period, their expertise may impact the patient’s outcome and quality of surgical care. With the involvement of anesthesia in interdisciplinary rounding, the patient may be optimized, and the plan of care may be more appropriate and individualized.

Examining The Relationship Between Lep Status And Delinquency Amongst High Schools Across America, Adrian Jesus Campos

Dissertations (2016-Present)

This research is intended to examine the relationship between the enrollment of Limited English Proficient (LEP) students in American high schools and the rate of delinquency on campus. While the stigma and general belief that immigrants and criminality are correlated has existed throughout American History, empirical research findings have generally indicated the inverse to be true and often find that immigrants engage in lower rates of delinquency in comparison to their non-immigrant counterparts. Previous work in the field has primarily identified immigrants by legal or technical categorization, primarily nativity and immigrant status. Fewer are the studies who identify this group …

Why Can’T I Have A Choice Of Companion During Labor? Barriers To Implementation Of Companion Presence, Anul Shifa Maknojia, Azwa Malik

Journal of Asian Midwives (JAM)

Companionship during labor gives comfort and reassurance to laboring women. Couples should experience this pivotal part of life together for its successful accomplishment. They bestow maternal support and ensure psychological wellbeing. However, there are some health care facilities who don’t permit the woman to bring a companion. The common barriers for not allowing companions during labor are: the utilization of traditional methods by companions, improper architectural layout, various ethnicities, and policies of hospitals. Thus, practical and realistic actions should be taken as discussed in the paper. Therefore, a laboring woman can utilize the choice of a companion during labor.

Effects Of Aging On Mouse Rotator Cuff Tendon Biomechanics, Chinmay Sagar Patwardhan

Bioengineering Theses - Archive

Rotator cuff tendon injuries and tear are caused by overuse, falling, or other accidents, and are often associated with old age. The severe injuries and tear can be debilitating and require nonsurgical treatment for partial tear and arthroscopic surgery for complete tear. The frequent location of injuries and tear are at the enthesis region, the interface where the tendon tissue gradually hardens and merges into the bone. Although aging has been identified as an important factor for rotator cuff tendon injuries and tear, how the mechanical properties of the bone-tendon complex evolve along with age is still a knowledge gap. …

Why Searle's Objection To Twin Earth Is Problematic, Paul F. Scheeler

Honors Theses

The philosopher John Searle wrote that, “The fundamental question in the philosophy of language has always been: How does language relate to reality?” For much of history, people assumed the answer to this question was “the mind”, and the debate was then about how the mind related language to reality. Starting in the 1970s, this view was challenged by the philosopher Hilary Putnam and others who claimed that meaning is not only in the mind but also involved the environment (a view known as semantic externalism). In this paper, I will give some background to Putnam’s semantic externalism and will …

Keynote Address, Godwin I. Emefiele Con

Economic and Financial Review

The theme for this year’s edition, “Food Security in Nigeria: Options for Policy” is apt and in tune with the existing realities of both the global and domestic economies, which have suffered heavily from the impact of the COVID-19 pandemic. In fact, the theme could not have come at a better time than now when issues of insecurity, climate change, and COVID-19 related disruptions are challenging food production and supply, not only in Nigeria but also globally. As a matter of fact, food security is critical for national security, economic stability and sustainable development.

Special Remarks, Kingsley Obiora

Economic and Financial Review

The theme of this year’s Seminar, Food Security in Nigeria: Options for Policy, is apt, timely and consistent with the current efforts of this administration and the Bank in finding sustainable solutions to the food security challenges confronting us as a nation. As we all know, food is a basic need of every man and key to socio-economic stability. The ability of a country to feed its people, and perhaps extend the surplus to other countries, is one of the key indicators of good standing in the comity of nations. The World Food Summit (1996), defined food security as a …

Addressing Food Insecurity In Nigeria: Lessons From Jurisdictional Experiences, Biodun Adedipe

Economic and Financial Review

The challenge of food security transcends national or regional boundaries, and indeed became a global concern in 2015 when the Sustainable Development Goals (SDGs) were set. Goal 2 targets zero hunger by 2030, and that is, to end hunger, achieve food security and improved nutrition, and promote sustainable agriculture. While the entire world is not in shortage of food, there are wide disparities in food sufficiency and food security across nations, regions and continents. The SDG No. 2 is a 5x1 matrix of five targets and three actions as summarised in Table 1. The targets are five critical elements of …

Rural Infrastructure And The Challenge Of Food Security In Nigeria, Idris A. Ayinde

Economic and Financial Review

Rural infrastructure, therefore, implies “the basic physical and organisational structures and facilities. In same vein, rural infrastructure are those forms of physical, social, human and institutional capital, which enhances rural dwellers better performance in the aspect of production, processing and distribution activities, as well as improving their overall quality of life.

Transforming The Agricultural Value Chain For Food Security In Nigeria: Any Role For Public-Private Partnership?, Stanislaus A. Ukeje

Economic and Financial Review

In the food sector, public-private-partnership (PPP) has the potential, not only to reduce the risk that farmers face, but also to improve the agricultural business environment. As the agricultural and rural sectors are the habitat of the poor, the best value chain strategy should be one that embodies poverty reduction, which can be achieved by increasing the incomes of smallholder farmers and rural dwellers.
