Exploring recurrences in quasiperiodic systems
… simplest form of dynamics exhibiting nontrivial recurrences, which are common in many nonlinear systems. The concept of recurrence was introduced to study the restricted three body problem and it is very useful for the characterization of nonlinear systems. I have analyzed in detail the …

Recurrences : exploiting naturally occurring analogues
In der vorliegenden Arbeit wird die Wiederkehr im Phasenraum ausgenutzt. Dabei werden drei Hauptresultate besprochen. 1. Die Wiederkehr erlaubt die Vorhersagbarkeit des Systems zu quantifizieren. 2. Die Wiederkehr enthaelt (unter bestimmten Voraussetzungen) sämtliche relevante Information über die …

Parallelization of dynamic programming recurrences in computational biology
The rapid growth of biosequence databases over the last decade has led to a performance bottleneck in the applications analyzing them. In particular, over the last five years DNA sequencing capacity of next-generation sequencers has been doubling every six months as costs have plummeted. The data …

Synchronization analysis by means of recurrences in phase space
Die tägliche Erfahrung zeigt uns, daß bei vielen physikalischen Systemen kleine Änderungen in den Anfangsbedingungen auch zu kleinen Änderungen im Verhalten des Systems führen. Wenn man z.B. das Steuerrad beim Auto fahren nur ein wenig zur Seite dreht, unterscheidet sich die Richtung des Wagens …

Theory, Techniques, and Experiments in Solving Recurrences in Computer Programs
… that we have determined useful in solving recurrences in computer programs. In chapter two we present a framework for understanding parallelism in computer applications based on an approach which models loop bodies as coalescing loop operators. In chapter three, we perform a case study of a …

Radiofrequency Lesion Assessment by Cardiac Magnetic Resonance Imaging following Atrial Fibrillation Catheter Ablation
… during ablation is important in determining recurrences. The nature of the RF lesion was studied using MRI with gadolinium delayed enhanced (DE) imaging and high signal T2 weighted imaging. Levels of DE and T2 were low in pre-procedural scans but rose dramatically immediately following the …

The Divisibility and Modular Properties of Kth-Order Linear Recurrences Over The Ring of Integers of an Algebraic Number Field With Respect to Prime Ideals
… + a(,2)w(,n+k-2) +...+ a(,k)w(,n). Those recurrences (u) satisfying (1) for which u(,0) = u(,1) =...= u(,k-2) = 0 and u(,k) = 1 are called unit sequences. Let f be the characteristic polynomial of the recurrence defined by (1). Let D be the discriminant of f. An ideal M is a maximal …

A comparison of techniques for identifying recurrent patterns of behavioral state in neonates
… variety of researchers have identified periodic recurrences in infant behavioral state with various time-series techniques, the appropriateness of techniques which identify periodic recurrences in all infants at all ages have been questioned. The purpose of this study was to compare the utility …

Prognostic and treatment predictive factors for radio- and chemotherapy resistance in breast cancer patients- a step towards personlized medicine
… I have focused on local relapse and distant recurrences, where the former is a tumor recurring in the same breast and the latter is distant spread in the body. I have focused on high through-put techniques, but have also evaluated one single factor, using immunohistochemistry. The most …

Exact Solutions to Lattice Models of Polymer Adsorption
… of weighted walks. If directed walks are used, recurrences may be formed and solved to study a variety of physical properties exactly. One solution method is to solve the recurrences with generating functions. Additionally, we may attempt to derive the partition function of the model, which …

Methods for Computing Genus Distribution Using Double-Rooted Graphs
… and to show how these can be used to obtain recurrences for the genus distribution of iteratively growing infinite graph families. (ii) to compute the genus distribution of a graph obtained (a) through the operation of self-vertex-amalgamation on a double-rooted graph, and (b) through the …

On the Stern sequence and a related sequence
… related sequence called w(n):=s(3n)/2. We give recurrences for the sequence and find generalized recurrences and a reduction formula. We attempt to find a combinatorial interpretation for w(n), as well as a generating function for the sequence. We also find the largest value of w(n) for a row of …

Integration of Biomedical Imaging and Translational Approaches For Management of Head and Neck Cancer
… Using this methodology, we showed that most recurrences occurred in the central high dose regions for patients treated with definitive IMRT compared with mainly non-central high dose recurrences after postoperative IMRT. We also correlated recurrences with pretreatment FDG-PET and identified …

Prognostic Value of Bone Marrow Micrometastasis Detected by Nnested RT-PCR for Cytokeratin 19 and Mammaglobin in Breast Cancer
… of 185 cytokeratin negative patients had distant recurrences. Mammaglobin was not correlated with distant recurrences. Bone marrow micrometastasis, stage, axillary nodal status, and estrogen receptor were independent. CONCLUSIONS: Bone marrow micrometastasis detected by nested RT-PCR for …

Topics in the Design and Analysis of Combinatorial Algorithms
… and maximization operators. Since such recurrences arise quite frequently in the analysis of the complexity and performance of algorithms it is important to develop techniques for their solution. The technique used is next applied to give precise solutions for the cost of optimal …

The process of the impact of differential response on child maltreatment recurrence
… appeared to be critical to reduce re-reports and recurrences rather than the DR. Emotional support was important for both positive service experiences and perceived matches that in return reduced re-reports and recurrences regardless of the pathway assignment. Practices and policies that are more …
