Motion in the solid state studied by NMR and extended time scale MD simulation
… of kinetic parameters across a large range of time-scales while MD can give insight into the form that the motion takes. The aim of the work presented in this thesis has been to demonstrate the extent of this complementarity by combining both techniques to investigate interesting systems, and …

All-Sky Search for Neutrinos Correlated with Gamma-Ray Bursts in Extended Time Windows Using Eight Years of IceCube Data
… with 2,091 gamma-ray bursts (GRBs) in prompt and extended time windows using data from the IceCube Neutrino Observatory ranging from May 2011 to October 2018. Ten time windows, ranging from 10 seconds to -1/+14 days around the time of the GRB's gamma-ray emission, were searched for coincident …

THE EFFECTS OF EXTENDED TIME ON READING COMPREHENSION PERFORMANCE FOR ENGLISH AS A SECOND LANGUAGE COLLEGE STUDENTS: IS THERE A NEED FOR ACCOMMODATIONS?
… particularly reading intensive tests under time constraints. This study examined the effects of extended time as a test accommodation on a timed reading comprehension test for ESL students compared to non-ESL peers under standard time, time and one half, and double time conditions. Results …

The impact of block scheduling on special education student learning in high school mathematics
… for certain special needs students because extended time on task sometimes leads to more discipline problems, especially for those students suffering from attention deficit disorder.</p>

Bayesian Hierarchical Modeling for Longitudinal Frequency Data
… regularly for several individuals over an extended time period. This model must recognize explicitly the discrete nature of the data, as well as any dependence that exists among an individual's time consecutive measurements. Motivated by a study investigating alternative treatments for …

Dinâmica e controle de caos de um sistema pendular com memória de forma
… are identified by their Lyapunov exponents. The extended time delay feedback technique is applied to control the system with two distinct types of controllers: a mechanical and a thermal. The stability of the orbits is identified using Floquet multipliers. Discussions about sub-harmonic orbits …

Multi-sensor rainfall data assimilation using ensemble approaches
… characterization of rainfall over an extended time period and spatial domain. The characterization takes the form of an ensemble of rainfall replicates, each conditioned on multiple measurement sources. The conditional replicates are obtained from ensemble data assimilation algorithms …

Studies of the low temperature anomaly in palladium hydride
… anomaly temperatures have been held below T for extended time a a periods. Resistance was seen to fall by up to 60% after several days of annealing. Reductions in annealing temperature caused further reductions in resistance. The changes are reversible; heating the samples to 90 K or more …

Epidermis and Re-epithelialization in <i>Schmidtea mediterranea</i>
… response to tissue damage or tissue loss for extended time (hours) and in high resolution. Using our methods, we followed planarian cells live for the first time and in conjunction with electron microscopy analysis we described epidermal cell behaviors during tissue maintenance, response to …

The Role of Cell Division Orientation during Zebrafish Early Development
… SDO in either of these processes. Making use of extended time-lapse, multi-photon microscopy and a careful three-dimensional analysis of cell division orientation, we show that SDO is required for neural rod midline formation during neurulation, but dispensable for body axis elongation during …

Multi-stakeholder quantitative analysis of sustainability for value delivery systems
… complexity of the value delivery process and the extended time frame to deliver value. In order to analyze the sustainability of Space Exploration, we use the hypothesis that only stakeholder groups that should be considered are those that control resources needed for the survival and growth of …

Complexity as a Form of Transition From Dynamics to Thermodynamics: Application to Sociological and Biological Processes.
… still extensive, occurs in an exceptionally extended time scale. Even, when the invariant distribution exists, the time necessary to reach the thermodynamic scaling regime is infinite. In the case where no invariant distribution exists, the complex system lives forever in a condition …

Parsimonious Mixed Bergomi Models for VIX Derivatives: Calibration and Estimation via Quantization
… they are not fast enough for calibration over extended time scales. In addition, the models are over-parameterised and lack dynamic estimation frameworks that incorporate both time-series and cross-sectional features of the VIX market. This dissertation addresses these challenges by developing …

The role of the Dgk1 and Pah1 in lipid interconversion on saccharomyces cerevisiae vacuole physiology, homeostasis, protein sorting and fusion
… to maintain fusion capacity when held for an extended time on ice. This deletion also had a unique protein profile, different from the wild type background, but not the inverse of the Pah1 deletion. The double deletion showed highly fragmented vacuoles, much like Pah1 deletion, though these …

A portfolio approach to energy governance : state management of China's coal and electric power supply industries
… policy, ownership and investment change over time. The results show that such devolution has been neither incrementally advancing nor consistently lacking, but has fluctuated according to the national electric power balance. The study suggests that China's central state actively manages the …

No Child Left Behind: Is it About Time? Elementary Scheduling Practices in the Commonwealth of Virginia Since the Authorization of NCLB
Time, the one educational resource educators desire most, is so often in short supply in America 's schools. The ability of the school administrator to schedule teachers' and students' time so that both groups can maximize opportunities for teaching and learning each day has become an essential …

The Evolution of Fitness After Prolonged Sperm Storage
… to many partners, female fitness is reduced by extended cohabitation and sexual interaction with males. Yet, even if repeated sexual interactions are harmful to females, limited male exposure will ultimately be detrimental due to sperm-depletion and infertility. Females are therefore expected to …

Analysis of RNA stability in forensic specimens
… obstacle for gene expression data where an extended time lag exists between death and sampling, and highlights the requirement for future work to consider novel data normalisation strategies. Overall, it is suggested that using RNA degradation as an indicator of post-mortem interval is …
