ℓ-CTP: Utilizing Multiple Agents to Find Efficient Routes in Disrupted Networks
… We utilize the Canadian Traveller’s Problem (CTP) to construct an online framework for utilizing multiple vehicles to discover low-cost paths through networks with failed edges unknown to one or more agents a priori. This thesis demonstrates the following results: first, we develop the ℓ-CTP …

Y-family DNA polymerase architecture: three structural features control accurate deoxy CTP insertion opposite N2-deoxy-guanine-benzo-a-pyrene
… Watson-Crick pairing between BP-N2-dG and dCTP, the BP moiety must be in the minor groove. On the minor groove side of the active site, k/IV/Dbh-class DNAPs have large openings that accommodate the BP moiety. Primer extension assays with purified proteins show that DNAP IV correctly inserts …

Comparison of Acetazolamide-Challenged CT Perfusion with Acetazolamide-Challenged SPECT in Moyamoya Patients
CT perfusion (CTP) is more readily accessible method for evaluation of cerebral perfusion than single photon emission CT (SPECT). We assessed whether there is any resting or drug-challenged CTP parameter correlating with cerebrovascular reserve (CVR) obtained by SPECT in moyamoya patients. …

Polymer-tethered epidermal growth factor as an inductive biomaterial surface for connective tissue progenitors
Connective tissue progenitors (CTP) can act as a pluripotent source of reparative cells during injury and therefore have great potential in regenerative medicine and tissue engineering. However, the response of CTP to most growth factors and cytokines is unknown. Many envisioned applications of …

Evaluating and improving collection tree protocol in mobile wireless sensor network
… mobile WSN scenarios. The simulation study shows CTP performs poorly in mobile scenario because of the frequent tree re-generation resulting from node movements. We compare Collection Tree Protocol with reactive ad hoc network routing protocols. The simulation results show that collection tree …

ANALYSIS OF TWO NOVEL COMPLEXES THAT REGULATE NEUROBLAST SELF-RENEWAL AND ASYMMETRIC DIVISION IN DROSOPHILA MELANOGASTER
… dynein light chain 1, also named Cut up (Ctp). Ctp localizes at centrioles and controls the mitotic spindle orientation in neuroblasts. Ctp directly interacts with a centriolar protein Anastral Spindle 2 (Ana2) and regulates the localization of Mushroom body defect (Mud). Ana2, Ctp and Mud …

Transcriptional Regulation of the Bacillus Subtilis pyrG Gene Encoding Cytidine Triphosphate Synthetase
… GGGC and GCUCCC sequences when intracellular CTP levels are low, which prevents the formation of the terminator and permits transcription readthrough. When intracellular CTP levels are high, I propose the regulatory protein dissociates from the pyrG leader RNA thereby allowing terminator …

Inter-Enterprise Cost-Time Profiling
… detailed consideration of the Cost-Time Profile (CTP) and the issues and factors that affect it, and the extension of the concepts to the new reality of Extended Enterprises. In a logical sequence, the basic concepts of CTP are defined and presented. Then, the extension of them to Inter-Enterprise …

IMPACT OF STRESS CARDIAC COMPUTED TOMOGRAPHY MYOCARDIAL PERFUSION ON DOWNSTREAM RESOURCES AND PROGNOSIS IN PATIENTS WITH SUSPECTED OR KNOWN CORONARY ARTERY DISEASE: A MULTICENTRE INTERNATIONAL STUDY - THE CTP-PRO STUDY
… Stress computed tomography perfusion (Stress-CTP) is a CT-based functional technique that can be added to coronary computed tomography angiography (cCTA) to improve management of patients with suspected coronary artery disease (CAD). The aim of the study is to evaluate the usefulness of …

Identifying Patients at Risk for Hyperperfusion after Carotid Stenting Using CT Perfusion with Acetazolamide Challenge
… reserve (CVR) by using CT perfusion (CTP) with acetazolamide (ACZ) challenge could identify patients at risk for hyperperfusion after CS. For 12 patients with symptomatic unilateral or bilateral carotid stenosis (> 70%), hemodynamic parameters including cerebral blood volume (CBV), …

Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
… angiography (CTCA) and myocardial CT perfusion (CTP) are promising techniques for the assessment of these factors. This thesis is comprised of several projects which explore refinements and new techniques aimed at improving diagnosis and risk stratification by CTCA. In order to improve CT …

A Study of the Pyrimidine Biosynthesis Pathway and its Regulation in Two Distinct Organisms: Methanococcus jannaschii and Pseudomonas aeruginosa
… enzyme by the nucleotide effectors ATP, CTP and UTP. In this research project we have genetically manipulated the M. jannaschii pyrI gene and have been able to assemble a 310 kDa E. coli like enzyme. By using the second methionine in the sequence we have shown that the enzyme from this …

A directional preference ETX measure for the collection tree protocol in mobile sensor networks
… was developed for the Collection Tree Protocol (CTP) in order to create longer lasting links. This thesis describes and measures the performance of this directional preference ETX measure utilizing various metrics such as Packet Reception Ratio, average number of beacon transmissions per node, …

Effector Response of the Aspartate Transcarbamoylase From Wild Type Pseudomonas Putida and a Mutant with 11 Amino Acids Deleted at the N-terminus of PyrB.
… also the effector binding sites for ATP, UTP and CTP at its N-terminus. In this work, 11 amino acids were deleted from the N-terminus of PyrB and the ATCase with the truncated protein was expressed in E. coli pyrB- and purified. The wild type enzyme was similarly treated. Velocity-substrate plots …

Part I: Strategies for the Synthesis of Monodisperse Polymers and Cyclic Polymers. Part II: Synthesis of Dipyrromethenes and Aza-dipyrromethenes from Aromatic Nitriles
… mini-review of catalyst transfer polymerization (CTP). This part of the chapter elucidates a number of common misunderstandings of CTP that are present in the literature. It goes onto suggest a new set of design principles to design new CTP systems for a wider variety of monomers. This leads into …

Socio-economic status and household catastrophic health expenditure in urban Argentina
… 2012/2013. Using the households capacity to pay (CTP) the proportion of households with CHE was estimated as those households that face health out-of-pocket above 40% of their CTP. A logistic regression was used to identify the determinants of CHE. To measure socioeconomic status a composite …

Mechanisms of piRNA-guided co-transcriptional gene silencing
… identified a fourth component of PICTS, Cut-up (Ctp), which I showed is essential for co-transcriptional transposon repression. While initially identified as a component of cytoplasmic dynein, Ctp has been shown to function as a dimerisation hub protein, mediating the assembly and stabilisation …
