Recent studies of polymers in solution and in bulk by energy transfer between two fluorescent labels are reviewed. Such studies are concerned with the equilibrium and dynamics of polymer chain expansion, molecular cluster formation in solution, the miscibility of polymers in bulk, and the interdiffusion of polymer latex particles.

Liquid-gated Graphene Field-Effect Transistors (GFET) are ultrasensitive bio-detection platforms carrying out the graphene’s exceptional intrinsic functionalities. Buffer and dilution factor are prevalent strategies towards the optimum performance of the GFETs. However, beyond the Debye length (λD), the role of the graphene-electrolytes’ ionic species interactions on the DNA behavior at the nanoscale interface is complicated. We studied the characteristics of the GFETs under different ionic strength, pH, and electrolyte type, e.g., phosphate buffer (PB), and phosphate buffer saline (PBS), in an automatic portable built-in system. The electrostatic gating and charge transfer phenomena were inferred from the field-effect measurements of the Dirac point position in single-layer graphene (SLG) transistors transfer curves. Results denote that λD is not the main factor governing the effective nanoscale screening environment. We observed that the longer λD was not the determining characteristic for sensitivity increment and limit of detection (LoD) as demonstrated by different types and ionic strengths of measuring buffers. In the DNA hybridization study, our findings show the role of the additional salts present in PBS, as compared to PB, in increasing graphene electron mobility, electrostatic shielding, intermolecular forces and DNA adsorption kinetics leading to an improved sensitivity.

Catch 22

Hyperreality is a key term in Jean Baudrillard’s cultural theory, designating a phase in the development of image where it “masks the absence of a profound reality.” The ambiance of Joseph Heller’s Catch-22 (1961) closely corresponds to Baudrillard’s notion of the hyperreal as images persist to precede reality in the fictional world of the novel. Since for Baudrillard each order of simulacra produces a certain mode of ideological discourse that impacts the perception of reality, it is plausible that the characters of this fictional context should be ideologically impacted by the hyperreal discourse. From this vantage point it is possible to have a new critical assessment of Yossarian’s (protagonist) antiheroic stance and study the role of the “business of illusion,” whose ideological edifice is based on the discourse of the hyperreal, on his antiheroic stance and actions. By drawing on Baudrillard’s cultural theory this paper aims to read Heller’s novel as a postmodern allegory of rebellion against the hyperreality of the twentieth-century American life and trace its relevance to modern-day U.S.

This article is dedicated to examination of the characteristics of the doctrine of Raja yoga in interpretation Of M. V. Lodyzhensky. The goal consists in the analysis and reconstruction of the system of Raja yoga within the religious-ethical philosophy of the thinker. In the course of this research, the author resolves a number of problems: examines the system of primary elements of religious-ethical philosophy of M. V. Lodyzhensky; analyzes the sources that affected the formation of views of the philosopher upon Raja yoga; reveals main characteristics of the system of Raja yoga within Lodyzhensky’s philosophy; determines the peculiarities of religious-mystical practice of Raja yoga in the philosophy of M. V. Lodyzhensky; defines the role of Raja-yoga within the system of religious-ethical philosophy of the thinker. The novelty lies in determination of the novel in comparison to the existing in scientific literature categories of M. V. Lodyzhensky’s philosophy and their analysis in the context of system of fundamental sections of philosophical knowledge (ontology, theology, anthropology, epistemology, axiology, ethics); as well as in comprehensive study of the system of Raja yoga in interpretation Of M. V. Lodyzhensky and determination of its role within the structure of his philosophy. It is established that the “core” of the system of religious-ethical philosophy of M. V. Lodyzhensky is the ethics develop ethics and axiology of Hesychasm developed by him. It is proven that the system of metaphysical categories and ideas of the thinker is of synthetic nature and leans on various cultural trends and traditions. The article demonstrates that special role within the system of Lodyzhensky’s philosophy is played by the apologetics of Hesychasm that implies critical review of the non-Christian mystical practices, among which is the examination of Raja yoga. The author underlines the uniqueness of interpretation of Raja yoga in the philosophy M. V. Lodyzhensky, as well as provides critical assessment to his interpretation of the system of Raja yoga.
