Pressure Controlled Topochemical Polymerization in Two-Dimensional Hybrid Perovskite

Mechanical pressure offers unique control over the energy landscape of chemical reactions, opening up pathways that are inaccessible through conventional thermochemistry. We hypothesize that the reduced dimensionality defines the conformational space of the high-pressure reaction, giving rise to new selectivity that is unavailable in 3D systems. Here, we demonstrate this concept through the pressure-controlled topochemical polymerization of the diacetylene molecule deca‐3,5‐diyn‐1‐amine (DDA) incorporated in the two-dimensional (2D) perovskite [DDA]2PbBr4. Compression at 3 GPa drives the first topochemical polymerization through 1,2 addition, forming a polyene product at room temperature. The reaction is initiated by the mechanical bending of the linear DDA molecule, a mechanism fundamentally different from the 1,4-addition in 3D solids. Importantly, pressure hinders the second 1,2-addition by disfavoring the gauche conformation between the remaining acetylene groups, allowing for the selective formation of polyene versus polyacene products. We characterize the reaction mechanisms and products using spectroscopies (Raman, X-ray photoelectron, ultraviolet-visible), X-ray diffraction and density-functional theory simulations. These results highlight the important role of dimensionality in high-pressure chemistry, and offers a new paradigm for creating low-dimensional functional materials.

Exploring the Impact of Adverse Childhood Experiences on Resilience, School Engagement and Success in Adolescents with Co-Occurring Autism Spectrum Disorder and Attention Deficit Hyperactive Disorder

There remains a dearth of literature that explains with no ambiguity, the complex relationships that exist between adverse childhood experiences (ACEs) and resilience, as well as school engagement and school in individuals with a co-occurring diagnosis of autism spectrum disorder (ASD) and attention deficit hyperactive disorder (ADHD). This study seeks to fill this missing gap in the literature. These research questions were answered using a retrospective cross-sectional study design of national secondary data from the National Survey of Children's Health (NSCH). The findings revealed that the more ACEs an individual had, the less they were likely to engage and succeed in school. A similar finding was obtained for resilience as individuals with more ACEs showed less resilience. However, counterintuitively to the hypothesis of the project, having both ASD and ADHD does not necessarily make these outcomes worse compared to having a singular diagnosis of either ASD or ADHD. The significance of this study is that it informs rehabilitation counselors as well as educators on the need for early identification of individuals with ASD and ADHD with a background of ACEs and commence interventions early enough to ensure they are more resilient and obtain improved success in school-related activities as well …

Improving Memory Performance for Both High Performance Computing and Embedded/Edge Computing Systems (open access)

Improving Memory Performance for Both High Performance Computing and Embedded/Edge Computing Systems

CPU-memory bottleneck is a widely recognized problem. It is known that majority of high performance computing (HPC) database systems are configured with large memories and dedicated to process specific workloads like weather prediction, molecular dynamic simulations etc. My research on optimal address mapping improves the memory performance by increasing the channel and bank level parallelism. In an another research direction, I proposed and evaluated adaptive page migration techniques that obviates the need for offline analysis of an application to determine page migration strategies. Furthermore, I explored different migration strategies like reverse migration, sub page migration that I found to be beneficial depending on the application behavior. Ideally, page migration strategies redirect the demand memory traffic to faster memory to improve the memory performance. In my third contribution, I worked and evaluated a memory-side accelerator to assist the main computational core in locating the non-zero elements of a sparse matrix that are typically used in scientific, machine learning workloads on a low-power embedded system configuration. Thus my contributions narrow the speed-gap by improving the latency and/or bandwidth between CPU and memory.

Exploring Flavonoid Glycosylation in Kudzu (Pueraria lobata)

The isoflavones in kudzu roots, especially the C-glycosylated isoflavone puerarin, have been linked to many health benefits. Puerarin contains a carbon-carbon glycosidic bond that can withstand hydrolysis. The C-glycosylation reaction in the biosynthesis of puerarin has not been thoroughly investigated, with conflicting reports suggesting that it could take place on daidzein, isoliquiritigenin, or 2,7,4ʹ-trihydroxyisoflavanone. Kudzu species were identified for use in comparative transcriptomics. A non-puerarin producing kudzu was identified as Pueraria phaseoloides and a puerarin producing kudzu was identified as Pueraria montana lobata. Through the use of the plant secondary product glycosyltransferase (PSPG) motif, glycosyltransferases (UGTs) were identified from the transcriptomes. The UGTs that had higher digital expression in P. m. lobata were examined further using additional tools to home in on the UGT that could be responsible for puerarin biosynthesis. One of the UGTs identified, UGT71T5, had previously been characterized from kudzu as a C-glycosyltransferase involved in puerarin biosynthesis through in vitro enzyme activity (with daidzein) and a gain of function approach in soybean hairy roots. Previous studies have not supported the end-product of a pathway such as daidzein as the target for C-glycosylation, and no genetic analysis of UGT function had been conducted in kudzu. The activity of …

Experiences of Parents of Preadolescents with Child–Parent Relationship Therapy

Preadolescence is a time of emotional, physical, social, and relational changes, which can lead to mental health concerns. Parents of preadolescents also experience changes within their roles as parents, and both parents and preadolescents experienced a wide range of changes and challenges during the COVID-19 pandemic. A mental health intervention focused on enhancing the parent-child relationship among parents of preadolescents is important for overall family functioning. This phenomenological study explored the experiences of parents of preadolescents after participating in a virtual child-parent relationship therapy (CPRT) intervention. Participants were seven parents ages 35 to 56 years-old with preadolescent children between the ages of 9 to 12 years-old. Semi-structured interviews were conducted following the CPRT intervention and analyzed. Six themes were found, including impact of group on learning, child's engagement with parent, child qualities, parent's understanding of self, importance of parent-child relationship, and integration of CPRT skills. The emerging themes indicated that the seven participants experienced changes in themselves, in their child, and in their parent-child relationships. Participants discussed their experiences with the virtual format and their integration of CPRT skills. The participants also reported feeling closeness and support from other group members, even with the virtual format. Findings from this study …

Classical Simulations of the Drift of Magnetobound States of Positronium (open access)

Classical Simulations of the Drift of Magnetobound States of Positronium

The production and control of antihydrogen at very low temperatures provided a key tool to test the validity for the antimaterial of the fundamental principles of the interactions of nature such as the weak principle of equivalence (WEP), and CPT symmetry (Charge, Parity, and Time reversal). The work presented in this dissertation studies the collisions of electrons and positrons in strong magnetic fields that generate magnetobound positronium (positron-electron system temporarily bound due to the presence of a magnetic field) and its possible role in the generation of antihydrogen.

The Effect of Online Consumer Reviews and Brand Equity on the Consumer Decision Making Process

This research aims to investigate the (1) review effects on consumer decision making process, (2) effects of negative reviews on brand equity, and (3) consumers' likely response to a brand's request for reviews. The objective of the first essay is to investigate the nature of the relationship between skepticism and consumer decision making in an online behavior context. Its second objective is to know whether people's belief on their abilities or their hedonic principle moderates the relationship between a person's skepticism toward online reviews and their reliance on online reviews. The objective of the second essay is to explore whether negative online reviews that focus on service quality specific dimensions have a different effect on a service organization's perceived brand equity. Its second objective is to analyze the role of emotional contagion in the relationship between negative reviews related to various service quality dimensions and its effect on perceived brand equity. The main objective of the third essay is to know whether consumers are more likely to write an online review for a brand when the request comes from a higher equity brand. This essay also investigates how message trust and persuasion knowledge influence the relationship between a brand's request …

Hybrid Optimization Models for Depot Location-Allocation and Real-Time Routing of Emergency Deliveries (open access)

Hybrid Optimization Models for Depot Location-Allocation and Real-Time Routing of Emergency Deliveries

Prompt and efficient intervention is vital in reducing casualty figures during epidemic outbreaks, disasters, sudden civil strife or terrorism attacks. This can only be achieved if there is a fit-for-purpose and location-specific emergency response plan in place, incorporating geographical, time and vehicular capacity constraints. In this research, a comprehensive emergency response model for situations of uncertainties (in locations' demand and available resources), typically obtainable in low-resource countries, is designed. It involves the development of algorithms for optimizing pre-and post-disaster activities. The studies result in the development of four models: (1) an adaptation of a machine learning clustering algorithm, for pre-positioning depots and emergency operation centers, which optimizes the placement of these depots, such that the largest geographical location is covered, and the maximum number of individuals reached, with minimal facility cost; (2) an optimization algorithm for routing relief distribution, using heterogenous fleets of vehicle, with considerations for uncertainties in humanitarian supplies; (3) a genetic algorithm-based route improvement model; and (4) a model for integrating possible new locations into the routing network, in real-time, using emergency severity ranking, with a high priority on the most-vulnerable population. The clustering approach to solving dept location-allocation problem produces a better time complexity, and the …
