Self-Assembly in Mixture of Surfactants and Stimuli-Responsive Polymers with Complex Architecture
Bogomolova, Anna ; Filippov, Sergej (advisor) ; Štěpánek, Miroslav (referee) ; Hanyková, Lenka (referee)
Title: Self-assembly in mixture of surfactants and stimuli-responsive polymers with complex architecture Author: Anna Bogomolova Department: Physical and Macromolecular Chemistry Supervisor: PhD. Sergey K. Filippov, IMC AS CR, v.v.i. Supervisor's e-mail address: filippov@imc.cas.cz Abstract: The issue of construction of complex multi-block copolymers is currently one of the most researched areas. It became a logic consequence of the continuous development in polymer chemistry. Nowadays, a great interest is attracted to multi- responsive block copolymers. As a rule, they consist of hydrophilic, hydrophobic and responsive blocks. That responsive block can be either thermo-sensitive or pH-sensitive as well as sensitive to some other external stimuli. In the present work, we will try to cover topic of stimuli-responsive block copolymers and their interactions with different types of surfactants. Understanding of polymer/surfactant interactions can be a crucial step for future modeling of drug/polymer or protein(DNA)/surfactant interactions. There is a great interest in the investigation of polymer-surfactant interactions. However, while the homopolymer-surfactant interactions are characterized well enough, the same interactions for block copolymers are poorly described. The main development in the latter topic...

Essays in Heterogeneous Learning
Bogomolova, Anna ; Slobodyan, Sergey (advisor) ; McGough, Bruce (referee) ; Molnar, Krizstina (referee)
5 Abstract Essays in Heterogeneous Learning by Anna Bogomolova My dissertation makes a contribution to the …eld of heterogeneous adaptive learning in macroeconomic models. This contribution is presented in the form of three research papers that constitute di¤erent chapters of my thesis. In the …rst chapter of my dissertation, "E-stability That Does Imply Learnability", I provide criteria and su¢ cient conditions for the stability of a structurally heterogeneous economy under the heterogeneous learning of agents, extending the results of Honkapohja and Mitra [36], Bogomolova and Kolyuzhnov [5], and Kolyuzhnov [40]. I provide general criteria (in terms of the corresponding Jacobian matrices) for stability under heterogeneous mixed RLS/SG learning for four classes of models: models without lags and with lags of the endogenous variable and with t- or t 1- dating of expectations, and provide su¢ cient conditions for stability for some simpler cases, where simpli…cations include either the diagonal structure of the shock process behaviour or the heterogeneous RLS learning. I also provide su¢ cient conditions for stability in terms of the structural heterogeneity independent of heterogeneity in learning ( -stability) in terms of E-stability of a suitably de…ned aggregate economy for all four classes of models...
