Various studies have observed that increased nutrient supply promotes the growth of bloom-forming cyanobacteria, but only a limited number of studies have investigated the influence of increased nutrient supply on bloom-forming cyanobacteria at the proteomic level. We investigated the cellular and proteomic responses of Microcystis aeruginosa to elevated nitrogen and phosphorus supply. Increased supply of both nutrients significantly promoted the growth of M. aeruginosa and the synthesis of chlorophyll a, protein, and microcystins. The release of microcystins and the synthesis of polysaccharides negatively correlated with the growth of M. aeruginosa under high nutrient levels. Overexpressed proteins related to photosynthesis, and amino acid synthesis, were responsible for the stimulatory effects of increased nutrient supply in M. aeruginosa. Increased nitrogen supply directly promoted cyanobacterial growth by inducing the overexpression of the cell division regulatory protein FtsZ. NtcA, that regulates gene transcription related to both nitrogen assimilation and microcystin synthesis, was overexpressed under the high nitrogen condition, which consequently induced overexpression of 2 microcystin synthetases (McyC and McyF) and promoted microcystin synthesis. Elevated nitrogen supply induced the overexpression of proteins involved in gas vesicle organization (GvpC and GvpW), which may increase the buoyancy of M. aeruginosa. Increased phosphorus level indirectly affected growth and the synthesis of cellular substances in M. aeruginosa through the mediation of differentially expressed proteins related to carbon and phosphorus metabolism. This study provides a comprehensive description of changes in the proteome of M. aeruginosa in response to an increased supply of 2 key nutrients.

This article presents a comprehensive analysis of the basic concepts that make up the conceptual sphere of the novel “Of Human Bondage” by W. S. Maugham. These concepts act as cognitive dominants of the linguistic consciousness of the protagonist’s linguistic personality in the work under study. The novelty of this research lies in the fact that it is performed within the framework of a new paradigm of linguistics — the cognitive linguistics, which involves the study of mental and linguistic representations of thought processes that occur during the perception of information. Moreover, the novel “Of Human Bondage” by W. S. Maugham has not attracted the attention of linguists-cognitologists previously, which adds to the novelty of this article. In addition, the present study provides a comprehensive description of the basic concepts making up the conceptual sphere of the novel. The linguistic methods of representing various concepts in the analyzed work are determined by the national, personal, cultural, and psychological aspects of Maugham’s thinking. The authors employ a communicative-cognitive methodological analysis proposed by N. S. Bolotnova involving the modeling of textual and intertextual semantic fields of artistic concepts and the analysis of the conceptual sphere of a literary text. The universal concepts RELIGION, LOVE, PASSION, THE MEANING OF LIFE, which constitute the conceptual sphere of the novel by W. S. Maugham “Of Human Bondage”, are analyzed. The main result of the study is that THE MEANING OF LIFE concept is universal, not individual, and it includes other universal concepts, such as RELIGION, LOVE, PASSION, THE MEANING OF LIFE, conceptual metaphors and metonyms, symbols, and other words-associates, which constitute the broad figurative and evaluative periphery of the conceptual sphere of the novel.

Defining the centrality of nodes and layers in multilayer networks is of fundamental importance for a variety of applications from sociology to biology and finance. This chapter presents the state-of-the-art centrality measures able to characterize the centrality of nodes, the influences of layers or the centrality of replica nodes in multilayer and multiplex networks. These centrality measures include modifications of the eigenvector centrality, Katz centrality, PageRank centrality and Communicability to the multilayer network scenario. The chapter provides a comprehensive description of the research of the field and discusses the main advantages and limitations of the different definitions, allowing the readers that wish to apply these techniques to choose the most suitable definition for his or her case study.

We present the design and experiment of a broadband optical parametric chirped-pulse amplifier (OPCPA) which provides high conversion efficiency and good beam quality at 808 nm wavelength. Using a three-dimensional spatial and temporal numerical model, several design considerations necessary to achieve high conversion efficiency, good beam quality and good output stability are discussed. To improve the conversion efficiency and broaden the amplified signal bandwidth simultaneously, the nonlinear crystal length and OPCPA parameters are analyzed and optimized with the concept of dissipating amplified idler between optical parametric amplification (OPA) of two crystals configuration. In the experiment, an amplifier consisting of two OPCPA stages of ‘L’ type configuration was demonstrated by using the optimized parameters. An amplified signal energy of 160 mJ was achieved with a total pump-to-signal efficiency of 35% (43% efficiency for the OPCPA stage 2). The output bandwidth of signal pulse reached 80 nm and the signal pulse was compressed to 24 fs. The energy stability reached 1.67% RMS at 3% pump energy variation. The optimized OPCPA amplifier operates at a repetition rate of 1 Hz and is used as a front-end injection for the main amplifier of SG-II 5PW laser facility.
