Several types of simultaneous approximation term (SAT) for diffusion problems discretized with diagonal-norm multidimensional summation-by-parts (SBP) operators are analyzed based on a common framework. Conditions under which the SBP-SAT discretizations consistent, conservative, adjoint and energy stable presented. For SATs leading to primal consistent discretizations, error in output functiona...

The virtual energy storage system (VESS) is one of the emerging novel concepts among current systems (ESSs) due to high effectiveness and reliability. In fact, VESS could store surplus inject during shortages, at power with larger capacities, compared conventional ESSs in smart grids. This study investigates optimal operation a multi-carrier VESS, including batteries, thermal (TES) systems, hyd...

Relapsing polychondritis (RP) is an autoimmune disease that affects extra-articular cartilage. Matrilin-1-induced relapsing polychondritis (MIRP) is a model for RP and is useful for studies of the pathogenic mechanisms in this disease. There are indications that the major histocompatibility complex (MHC) class II plays a major role in RP, since DR4+ patients are more commonly affected than cont...

PURPOSE Hepatocellular carcinoma (HCC) is a rapidly growing tumor associated with a high propensity for vascular invasion and metastasis. Epithelial-mesenchymal transition (EMT) is a key event in the tumor invasion process. Recently, Twist has been identified to play an important role in EMT-mediated metastasis through the regulation of E-cadherin expression. However, the actual role of Twist i...

Discretization methods for ordinary differential equations are usually not exact; they commit an error at every step of the algorithm. All these errors combine to form the global error, which is the error in the final result. The global error is the subject of this thesis. In the first half of the thesis, accurate a priori estimates of the global error are derived. Three different approaches ar...

In earlier studies from our laboratory, mice that are nonresponders (H2P, H29, H-28) to the terpolymer of L-glutamic acids°-L-alanine3°-L-tyrosine'° (GAT)' were shown to develop suppressor T cells capable of inhibiting GAT-specific responses to GAT complexed with methylated bovine serum albumin (GATMBSA) (1). This finding raised several important points: (a) Could suppressor T cells be demonstr...

Extensive investigations of asymmetric intermolecular cyclopropanation of terminal alkenes with diazoacetates catalyzed by ruthenium porphyrin [Ru(P*)(CO)(EtOH)] (1, H2P = 5,10,15,20-tetrakis[(1S,4R,5R,8S)-1,2,3,4,5,6,7,8-octahydro-1,4:5,8-dimethanoanthracene-9-yl]porphyrin) and the application of catalyst 1 to asymmetric intramolecular cyclopropanation of allylic or homoallylic diazoacetates a...
