Análisis de las novelas del realismo postmoderno americano
No full textEn el último cuarto del siglo pasado, el realismo tradi- cional y el posmodernismo en la literatura mundial se cho- caron y se fusionaron entre sí en gran medida. Pensadores, académicos y escritores comenzaron a ver la forma, temas e incluso la estética del realismo tradicional en una forma nueva y realmente posmoderna. En los albores de la década de 1980, muchos nuevos escritores de Estados Unidos co- menzaron a atraer, por la forma de pensamiento, cada día más atención del círculo crítico. El presente artículo ofrece una discusión y análisis de algunas novelas representativas de los autores de la época
Coexistence of strong and weak pulses in a fiber laser with largely anomalous dispersion
No full textThe coexistence of weakly sech-shaped solitons and strongly dissipative solitons is experimentally observed in an ultra-large net-anomalous-dispersion mode-locked fiber laser for the first time to author's best knowledge. Both sech-shaped and dissipative solitons appear to be the asymmetrically combined pulse state with one pulse component much smaller than the other. The energy of dissipative solitons is over three orders of magnitude larger than that of sech-shaped solitons. Two different types of pulse-shaping mechanisms coexist in the laser: one is the dissipative processes and the other is the balance between anomalous dispersion and nonlinear Kerr effect. Numerical simulations and analysis confirm the experimental observations. (c) 2011 Optical Society of Americ
A dual-wavelength sampled fiber Bragg grating and its application in L-band dual-wavelength erbium-doped fiber lasers
No full textA novel dual-wavelength (DW) sampled fiber Bragg grating (SFBG) is proposed and demonstrated for the first time to the author's best knowledge. This kind of SFBG can realize a DW operation with uniform reflection peaks rather than multiple nonuniform peaks shown in conventional SFBGs. Based on the designed SFBG, we have proposed a novel L-band DW erbium-doped fiber laser, which has such a unique merit that the spacing of the two wavelengths keeps unchanged during tuning laser
Design of superstructure fiber Bragg gratings with a Fourier analysis technique and its applications to multiple ultranarrow transmission gratings
No full textSuperstructure fiber Bragg gratings (FBGs) have been comprehensively analyzed with Fourier theory and experimentally demonstrated. By using Fourier transforms, it has been proven that (1) the traditional uniform FBG produces only a single response in the spectrum, (2) multiple phase-sampled gratings can be regarded as independent interleaved FBGs with different phases, and (3) the multiple phase sampling technique has the capacity to densify the spectral channels. Based on Fourier theory, for the first time to the author's knowledge, a kind of superstructure FBGs with multiple ultranarrow transmission windows, obtained by introducing a pi phase shift into the center of grating, is proposed and has been confirmed experimentally.

Reconfiguration of the proteasome during chaperone-mediated assembly
No full textThe proteasomal ATPase ring, comprising Rpt1-Rpt6, associates with the heptameric α ring of the proteasome core particle (CP) in the mature proteasome, with the Rpt C-terminal tails inserting into pockets of the α ring[superscript 1-4]. Rpt ring assembly is mediated by four chaperones, each binding a distinct Rpt subunit[superscript 5-10]. We report that the base subassembly of the proteasome, which includes the Rpt ring, forms a high affinity complex with the CP. This complex is subject to active dissociation by the chaperones Hsm3, Nas6, and Rpn14. Chaperone-mediated dissociation was abrogated by a nonhydrolyzable ATP analog, indicating that chaperone action is coupled to nucleotide hydrolysis by the Rpt ring. Unexpectedly, synthetic Rpt tail peptides bound α pockets with poor specificity, except for Rpt6, which uniquely bound the α2/α3 pocket. Although the Rpt6 tail is not visualized within an α pocket in mature proteasomes[superscript 2-4], it inserts into the α2/α3 pocket in the base-CP complex and is important for complex formation. Thus, the Rpt-CP interface is reconfigured when the lid complex joins the nascent proteasome to form the mature holoenzyme

Management of economic security in the field of financial and credit relations
No full textScientific advisor: Morozova N., PhD in economics, associate professor, department management, business and professional communicationsThe object of research is a process of ensuring economic security in the field of financial and credit relations. The subject of research covers the scientific and methodological principles and practical aspects of ensuring the economic security of the banking system as an important component of the financial and credit sphere of the economy. The purpose of the master's thesis is a theoretical justification and development of practical proposals for strengthening the economic security of the banking system and participants in financial and credit relations in conditions of economic instability. Tasks of a qualifying master's thesis include: to reveal the essence and role of economic security in the financial and credit sphere; to study the peculiarities of the system of financial and economic security of the banking sector and approaches to assessing its effectiveness; summarize the strategic aspects of ensuring the economic security of subjects of financial and credit relations; to analyze the level of economic security of the banking system of Ukraine; provide the organizational and economic characteristics of Credit Agricole Bank JSC; to assess the level of economic security of Credit Agricole Bank JSC; to generalize promising directions for strengthening the economic security of the banking system of Ukraine; justify directions for improving the subsystems of ensuring the economic security of the banking sector of the Ukrainian economy; to determine the peculiarities of credit risk management of banking institutions in the conditions of martial law. Based on the results of the research, theoretical and practical provisions have been formulated, which the author has developed into concrete proposals for ensuring economic security in the field of financial and credit relations
