An Acyl Radical Cascade Model for the Total Synthesis of Lyconadin A
… on a novel 7-exo-trig/6-exo-trig acyl radical cascade cyclization. The synthesis of model acyl radical cascade precursor 23 will be presented. Key features of this synthesis include the suppression of competing elimination during the alkylation of a hindered phenethyl bromide and the use of a …

A Developmental Cascade Model of Neurocognitive Functioning: Risk, Resilience, and Implications for Children's Mental Health
… This dissertation delineates a developmental cascade model of ToM and EF in which key social-cognitive skills in the second year of life are examined as precursors to ToM and EF through their impact on children's nascent language skills. Further, both cumulative social disadvantage and …

A Developmental Cascade Model of Maltreatment, Delay Discounting, and Health Behaviors across Adolescence and Young Adulthood
… at each time point. We used a developmental cascade model with autoregressive, cross-lagged, and cross-sectional associations to examine the longitudinal multivariate change processes and indirect effects from maltreatment exposure during adolescence to delay discounting and health-promoting …

A Riverine Ecosystem Service Cascade Model (RESCaM) framework for assessing ecosystem service provision as applied to English geomorphic river types
… been placed within a Riverine Ecosystem Service Cascade Model (RESCaM) framework. A geomorphic river type classification, recognising thirteen geomorphic river types commonly found in England, is further integrated within the approach to provide the template for which to evaluate ecosystem …

Predicting performance on fluid intelligence from speed of processing, working memory, and controlled attention
… intelligence are currently explained by the Cascade model (Fry & Hale, 1996) and the Controlled Attention hypothesis (Engle, Kane, & Tuholski, 1999; Kane & Engle, 2002). The first theory is based on a complex relation among age, speed, and working memory which is described as a Cascade. The …

An Accelerator Measurement of Atomic X-ray Yields in Exotic Atoms and Implications for an Antideuteron-Based Dark Matter Search
… experiment. Recently, we have developed a simple cascade model and the parameters were fitted with the experimental results. The cascade model was extended to the antideuteronic exotic atom for the GAPS flight experiment. GEANT4 simulation was conducted to obtain optimized cuts on the timing, …

A systematic exploration of perceptual and semantic differences in category-specific object-processing using magnetoencephalography
… for living objects. Our findings support the cascade model of object naming (Humphreys et al., 1988). In addition, our findings using normal participants demonstrate early, category-specific perceptual differences. These findings are corroborated by our patient study. In our assessment of the …

System identification and modeling of primary electrosensory afferent response dynamics in the weakly electric fish Apteronotus leptorhynchus
… stimuli, we have constructed a linear-nonlinear cascade model to describe the response properties of P-type afferents. We use parametric system identification technique to quantitatively characterize the response dynamics of the system. Comparisons of experimental data and model predictions to …

Sediment transport modelling at the catchment scale in Alpine streams
… this context, new advances in sediment transport modelling acquire a relevant role, especially in mountain streams. The work of the present Ph.D. thesis mainly focuses on new methodologies to enhance sediment transport modelling at the catchment scale. In particular, the present work aims at the …

Development of Speed, Memory, and Fluid Reasoning in Children
… are not well understood. The developmental cascade model proposed by Fry and Hale: 1996) suggests that age related improvements in speed of processing are related to improvements in working memory, which in turn influence fluid reasoning. Recent research in adults suggests secondary memory …

Influence Graphs for Modeling of Cascading Failures in Electric Distribution Networks
… <p>This paper focuses on the development of a cascade model in a distribution network using Newton-Raphson’s power flow method to study the impact of random line failures on other lines in the system. The random line failures are initiated to mimic the occurrence of severe events. The objective …

Studies on the biosynthesis of oudenone and verucopeptin
… of 70 into 67 is analogous to the "polyepoxide cascade" model, which has been previously implicated in the biosynthesis of polyether antibiotics.* The antitumor metabolite verucopeptin ( 89 ) is structurally characterized by a polyketide-derived tetrahydropyranyl side chain and a 19-membered …

Particles Inside Particles: The Flow of Energy in Quarks, Gluons, and Jets
… partonic physics, and presenting the partonic cascade model of jet formation and jet substructure. Noting the ubiquitous presence of low-energy pollution in particle collision events, in the forms of hadronization, detector effects, the underlying event (UE), and pileup (PU), we then move …

Machine Learning Methods for Churn Prediction and Infrastructure Resilience
… I develop an upgrades-informed churn forecasting model tailored specifically for marketing operations. Recognizing limitations in the existing aggregate forecasting methodologies, I create a cohort-based cascade model that explicitly integrates customer upgrade behavior across various contract …

Preliminary design tools in turbomachinery: Non-uniformly spaced blade rows, multistage interaction, unsteady radial waves, and propeller horizontal-axis turbine optimization
… CFD analyses. Four analytical/semi-analytical models are developed in this study: 1) a generalized flat plate cascade model for investigating the unsteady aerodynamics of a blade row with non-uniformly spaced blades; 2) a multistage interaction model for investigating rotor-stator interactions; …

Biases in Looking Behaviour during Visual Decision Making Tasks
… order to test predictions derived from the Gaze Cascade model (Shimojo et al., 2003). In Experiment 3, participants performed an eight alternative decision in which four of the items had been pre-exposed prior to the decision. In Experiment 4, stimulus exposure was manipulated during the ongoing …

The Effect of Blade Row Interaction on Rotor Film Cooling
… interaction is not captured in flat-plate and cascade testing, or present design methods, contributing to uncertainty in predicted cooling performance. The aims of this thesis are to establish the mechanisms by which blade row interaction affects rotor film cooling, and quantify their influence …

The relative importance of the BRWI and BRTE noise sources is investigated for a realistic CROR configuration at assumed take-off, cruise and approach-type conditions. It is predicted that both broadband noise sources are significant at …

An integrated neurovascular investigation of cognitive aging
… dissertation, I integrate these factors into a cascade model and show how they might jointly and hierarchically account for individual differences in cognitive aging. The aim here is to have a framework that provides a starting point from which mechanistic pathways can be revealed and tested, …
