M²Brtpc: A Novel Modified Multimodal Biometric Recognition For Toddlers And Pre-School Children Approach, Mahmoud Bahzad, Labib M. Labib, Mostafa Elhosseini, Mahmoud Badawy

Mansoura Engineering Journal

A biometric system based on the characteristics of adults recently achieved an outstanding result. Over the last few decades, many applications have been developed for adults, such as fingerprint, face, iris, and hand-vein. Infant identification suffers from many problems and does not enroll all possible ages. Identifying children using one or any biometric features is the first step in ensuring that they are recognized before the law and that their rights are guaranteed. From another perspective, this prevents baby swaps in hospitals, Identifying Missing Children, and Civil ID Programs. This paper introduces an approach for Multimodal Biometric Recognition for Toddlers …

Enzymes populate ensembles of structures with intrinsically different catalytic proficiencies that are difficult to experimentally characterize. We use time-resolved mix-and-inject serial crystallography (MISC) at an X-ray free electron laser (XFEL) to observe catalysis in a designed mutant (G150T) isocyanide hydratase (ICH) enzyme that enhances sampling of important minor conformations. The active site exists in a mixture of conformations and formation of the thioimidate catalytic intermediate selects for catalytically competent substates. A prior proposal for active site cysteine charge-coupled conformational changes in ICH is validated by determining structures of the enzyme over a range of pH values. A combination of large …

Center for Brain, Biology, and Behavior: Faculty Publications

Mild traumatic brain injury is a complex neurological disorder of significant concern among athletes who play contact sports. Athletes who sustain sport-related concussion typically undergo physical examination and neurocognitive evaluation to determine injury severity and return-to-play status. However, traumatic disruption to neurometabolic processes can occur with minimal detectable anatomic pathology or neurocognitive alteration, increasing the risk that athletes may be cleared for return-to-play during a vulnerable period and receive a repetitive injury. This underscores the need for sensitive functional neuroimaging methods to detect altered cerebral physiology in concussed athletes. The present study compared the efficacy of Immediate Post-concussion Assessment and …

Automated Processing Of Metabolomics Data For Population-Scale Studies, Ethan Stancliffe

Arts & Sciences Graduate Student Theses and Dissertations

The growth of untargeted metabolomic profiling technology has prompted the upstart of many large cohort studies. Metabolomics serves as an informative complement to other more established ‘omics (e.g., genomics, transcriptomics, proteomics). As a younger discipline, however, experimental and computational workflows are non-standardized and at times inadequate for large-scale studies. Two primary limitations in analysis of untargeted metabolomics data are 1) the poor performance and scalability of the algorithms applied to detect metabolite signals from the raw LC/MS data and 2) inefficient and arduous metabolite identification, which is the process of determining the biochemical structures that correspond to the detected LC/MS …

Potential Of Nano Hydroxyapatite Synthesized From Blood Clam Shells As A Remineralizing Agent After In-Office Bleaching, Noor Hikmah, Maria Tanumihardja, Juni J. Nugroho, Nurhayaty Natsir, Nurlindah Hamrun, Syahruddin Kasim

Journal of Dentomaxillofacial Science

Introduction: The effect of bleaching on tooth structure is the loss of interprismatic substance which causes prism irregularities and changes in enamel morphology such as increased porosity and demineralization. This can be stopped by encouraging remineralization if the pH is neutralized and there are enough calcium and phosphate ions in the oral cavity. One agent that can be used to help the remineralization process is nano hydroxyapatite (nHA) which is a bioactive and biocompatible material for the natural mineral enamel. This study aims to determine change in the percentage of porosity, calcium, phosphate and hydroxyapatite synthesized from blood clam shells …

Critical Engagements With Award Winning Picturebooks: My Journey In Creating A More Equitable Classroom Library, Carrie Elizabeth Crowe

Theses and Dissertations

Research consistently shows that students from historically marginalized populations have difficulty accessing texts that represent the realities of their lives. Concerned that such might be the case for my students, I conducted an inventory of my classroom library and sought out award-winning texts that could make my library more diverse and inclusive. I then analyzed these award-winning texts using Bishop's (1992) categories of multicultural literature in order to better understand the picturebooks' underlying messages and ideologies. My examinations showed that the majority of the texts fit into the same category (culturally specific), though I was able to identify award-winning texts …

Terahertz From Electrons, Electronics From Terahertz, Clayton D. Moss

Theses and Dissertations

Time-domain terahertz spectroscopy (THz-TDS) is a valuable technique for studying collective ultrafast phenomena. Several mechanisms exist for converting ultrashort optical laser pulses into coherent THz sources. Broadband THz pulses can be obtained from electron currents in air plasma, which requires combinations of different colors of light to be most effective. I report multi-color generation schemes of THz pulses that deliver coherent THz output. Experimental and theoretical work using the photocurrent model describe ways to use non-harmonic color combinations to utilize several sources of light available in a table-top laser setup. Additionally, THz-TDS is used to study a variety of ultrafast …

Masters Projects

Abstract

Introduction

The study investigated the consistency of free breathing planning margins for fractionated SBRT treatment in the lung. The study compared breathing motion from the average CT (AVE CT) scan to the Cone Beam Computed Tomography (CBCT) from each treatment session. Various breathing techniques were also discussed, including deep inspiration breath hold (DIBH), gated breathing, abdominal compression (AC), and free breathing (FB). Free-breathing may lead to overdosing on surrounding healthy tissue if significant changes in breathing amplitude occur. Abdominal compression or breath hold may reduce abnormal breathing movement if erratic breathing occurs. The study's aim was to ensure the …

Platelet-Derived Exerkine Cxcl4/Platelet Factor 4 Rejuvenates Hippocampal Neurogenesis And Restores Cognitive Function In Aged Mice, Odette Leiter, David Brici, Stephen J Fletcher, Xuan Ling Hilary Yong, Jocelyn Widagdo, Nicholas Matigian, Adam B Schroer, Gregor Bieri, Daniel G Blackmore, Perry F Bartlett, Victor Anggono, Saul A Villeda, Tara L Walker

Faculty, Staff and Student Publications

The beneficial effects of physical activity on brain ageing are well recognised, with exerkines, factors that are secreted into the circulation in response to exercise, emerging as likely mediators of this response. However, the source and identity of these exerkines remain unclear. Here we provide evidence that an anti-geronic exerkine is secreted by platelets. We show that platelets are activated by exercise and are required for the exercise-induced increase in hippocampal precursor cell proliferation in aged mice. We also demonstrate that increasing the systemic levels of the platelet-derived exerkine CXCL4/platelet factor 4 (PF4) ameliorates age-related regenerative and cognitive impairments in …
