How James Kept the Pace?; A Look into the Organic Unity of Daisy Miller
Get PDFMany Critics believe that Henry James has set the definitive standards of modern fiction writing. Undoubtedly his groundbreaking article “The Art of fiction,” which published for the first time in 1884, has a major contribution in developing the theories of fiction writing. The term Organic Unity has derived from a major Formalist Critic, Cleanth Brooks. Both James and Brooks believed that a critic should approach a text as an organic whole. So, in this article we try to pinpoint the ideas which James and Brooks claimed in their essays and see how these ideas conform to one of James’ well-known stories, Daisy Miller. We want to observe that how James develops and shapes his story around the central theme. Furthermore, we want to investigate that are there any literary devices embedded in the text of the story which help James to deliver his fiction with artistry?Keywords: James, Cleanth Brooks, Organic Unity, The Art of Fiction, Daisy Mille
Damage accumulation analysis of cfrp cross-ply laminates under different tensile loading rates
Get PDFThis paper investigates the loading rate effect on both mechanical properties and damage accumulation process of [0°2/90°4]S carbon fiber-polymer laminates under tensile loading. In-situ edge observations, Acoustic Emission and Digital Image Correlation techniques were utilized simultaneously to monitor the state of damage in real time. Results showed that the axial modulus and strength were less sensitive to loading rates than failure strain, which increased with the decrease of the loading rate. In the viewpoint of damage accumulation process, high density and uniform distribution of transverse matrix cracks, and H-shape crack patterns, incorporating inter-laminar cracks, were more likely to occur at low loading rates while variable crack spacing occurred at higher rates. When loading rates were lower than a certain level, maximum transverse matrix crack density decreased slightly due to the restriction of relatively widely generated inter-laminar cracks. Furthermore, the cumulative acoustic emission energy of low-frequency signals was linearly correlated to transverse matrix crack density, providing a promising way to quantify crack accumulation in real time. Finally, spatial consistence was observed between transverse matrix cracks at edges and stress concentrations at the exterior 0° ply, and the peaks of axial strain at local concentration regions locate either near the newest cracks or at the place with minimum crack spacing.Structural Integrity & Composite

Joint Trajectory and Power Allocation Design for Secure Artificial Noise Aided UAV Communications
No full textThis paper investigates an average secrecy rate (ASR) maximization problem for an unmanned aerial vehicle (UAV) enabled wireless communication system, wherein a UAV is employed to deliver confidential information to a ground destination in the presence of a terrestrial passive eavesdropper. By employing an artificial noise (AN) injection based secure two-phase transmission protocol, we aim at jointly optimizing the UAV's trajectory, network transmission power, and AN power allocation over a given time horizon to enhance the ASR performance. Specifically, we divide the original non-convex problem into four subproblems, and propose a successive convex approximation based efficient iterative algorithm to solve it suboptimally with guaranteed convergence. Simulation results demonstrate significant security advantages of our designed scheme over other known benchmarks, particularly for stringent flight durations.Manuscript received June 16, 2020; revised November 11, 2020 and December 14, 2020; accepted February 2, 2021.

Barely visible impact damage assessment in laminated composites using acoustic emission
Get PDFDespite the key advantages of Fiber Reinforced Polymer (FRP) composites, they are susceptible to Barely Visible Impact Damage (BVID) under transverse loadings. This study investigates BVID in two quasi-isotropic carbon/epoxy laminates under quasi-static indentation and Low-Velocity Impact (LVI) loadings using Acoustic Emission (AE). First, the evolution of interlaminar and intralaminar damages is studied by analyzing the AE signals of the indentation test using b-value and sentry function methods. Then, the specimens are subjected to the LVI loading and the induced damages are compared with the indentation test and the percentage of each damage mechanism is calculated using Wavelet Packet Transform (WPT). In consistent with the mechanical data, ultrasonic C-scan and digital camera images of the specimens, the AE results show a considerable similarity between the induced BVID under quasi-static indentation and LVI tests. Finally, the obtained results show that AE is a powerful tool to study BVID in laminated composites under quasi-static and dynamic transverse loadings.</p
Offenbarung als Selbstmitteilung Gottes
No full textThe author specifies the meaning of revelation as God's "self-communication" by distinguishing that concept from the understanding of revelation as divine afflatus on the one hand and as supernatural information on the other hand. He then traces back that concept to the Philosophy of German Idealism, mainly Hegel, and shows how that approach became adopted by theologians in the 19 th century, for example by Philipp Konrad Marheineke. In the next part of the article (self-) revelation is spelled out in reference to the term "disclosure" ("Erschließung") which was used by Heidegger. In the final reflection the author suggests to understand the content of self-revelation - from a Christian point of view - as kenosis : God reveals himself as a deity who makes himself present in a human being, gets affected by the suffering of that being and overcomes the abyss of death that separates that being from God
Clustering of interlaminar and intralaminar damages in laminated composites under indentation loading using acoustic emission
Get PDFThis study focuses on the clustering of the indentation-induced interlaminar and intralaminar damages in carbon/epoxy laminated composites using Acoustic Emission (AE) technique. Two quasi-isotropic specimens with layups of [60/0/-60]4S (is named dispersed specimen) and [604/04/-604]S (is named blocked specimen) were fabricated and subjected to a quasi-static indentation loading. The mechanical data, digital camera and ultrasonic C-scan images of the damaged specimens showed different damage evolution behaviors for the blocked and dispersed specimens. Then, the AE signals of the specimens were clustered for tracking the evolution behavior of different damage mechanisms. In order to select a reliable clustering method, the performance of six different clustering methods consisting of k-Means, Genetic k-Means, Fuzzy C-Means, Self-Organizing Map (SOM), Gaussian Mixture Model (GMM), and hierarchical model were compared. The results illustrated that hierarchical model has the best performance in clustering of AE signals. Finally, the evolution behavior of each damage mechanism was investigated by the clustered AE signals with hierarchical model. The results of this study show that using AE technique with an appropriate clustering method such as hierarchical model could be an applicable tool for structural health monitoring of composite structures
Molecularly imprinted nanoparticles reveal regulatory scaffolding features in Pyk2 tyrosine kinase
Get PDFPyk2 is a multi-domain non-receptor tyrosine kinase that serves dual roles as a signaling enzyme and scaffold. Pyk2 activation involves a multi-stage cascade of conformational rearrangements and protein interactions initiated by autophosphorylation of a linker site. Linker phosphorylation recruits Src kinase, and Src-mediated phosphorylation of the Pyk2 activation loop confers full activation. The regulation and accessibility of the initial Pyk2 autophosphorylation site remains unclear. We employed peptide-binding molecularly imprinted nanoparticles (MINPs) to probe the regulatory conformations controlling Pyk2 activation. MINPs differentiating local structure and phosphorylation state revealed that the Pyk2 autophosphorylation site is protected in the autoinhibited state. Activity profiling of Pyk2 variants implicated FERM and linker residues responsible for constraining the autophosphorylation site. MINPs targeting each Src docking site disrupt the higher-order kinase interactions critical for activation complex maturation. Ultimately, MINPs targeting key regulatory motifs establish a useful toolkit for probing successive activational stages in the higher-order Pyk2 signaling complex.This article is published as Zanela, Tania M.

Slow recognition of seminal papers and fast growth of author connectivity in economics
Get PDFA bird’s-eye view of the economics literature and its temporal evolution during the last three decades is provided by analysing titles, abstracts, keywords, reference lists and author affiliations of nearly 204,000 economics papers. Major divisions of the literature are objectively identified through exploring patterns of term co-mention in their titles and abstracts. Temporal research trends are also quantified, and influential references are determined through patterns of co-citation of references in the reference lists of these papers. Analyses show that the literature of economics tends to lag in the adoption of emerging research and is reliant on a traditional knowledge base. Of more than 1,250 references that have had a local burst of citation, the average and maximum gap between their publication year and the onset of recognition has been respectively 10 and 47 years. Influential economics papers typically have to wait for a decade before their recognition comes along, and this phenomenon has intensified over the last three decades. Another observation is the sharp rise in author connectivity and globalisation in economics research. International collaboration in the field of economics shows a distinct acceleration since 2013. If current trend continues, in few years, the number of internationally collaborated economics papers published each year will surpass that of domestically produced papers. Economists may be traditionalists, in that, they are hesitant in giving recognition to new research or creating new research trends, but they cannot be considered insular, as they have become notably well-connected and collaborative
