    Abstract We suggest an analytical approach to the adaptive thresholding in a shape anomaly detection problem. We find an analytical expression for the distribution of the cosine similarity score between a reference shape and an observational shape hindered by strong measurement noise that depends solely on the noise level and is independent of the particular shape analyzed. The analytical treatment is also confirmed by computer simulations and shows nearly perfect agreement. Using this analytical solution, we suggest an improved shape anomaly detection approach based on adaptive thresholding. We validate the noise robustness of our approach using typical shapes of normal and pathological electrocardiogram cycles hindered by additive white noise. We show explicitly that under high noise levels our approach considerably outperforms the conventional tactic that does not take into account variations in the noise level.

    Abstract The first step of the interaction between Ag(0) nanocomposite with antiatherogenic anticoagulant sulfated arabinogalactan involves the transportation and concentration of antimicrobial nanosilver in the bacteria target (E. coli). Further, the silver ions in dynamic equilibrium with metal backbone of the nanoparticles (NPs) reach the membrane surface and bond with this surface. Simultaneously, the redox interaction of silver cations with main reducing components of the membrane surface is triggered to afford the zero-valence silver atoms that are stabilized to form metal clusters, or new NPs of silver. Size and morphology of these NPs are defined by specific conditions of their synthesis involving the microorganism membrane: The Ag(0) NPs formed on membranes and fragments of the destroyed bacteria have other morphology (including triangular) and smaller sizes in comparison with the initial nanocomposite that additionally enhances antimicrobial activity of such NPs.
    From the clinical editor: This study investigates silver nanocompistes (Ag(0) NPs) and their interaction with antiatherogenic anticoagulant sulfated arabinogalactan. A complex set of interactions are described, leading to Ag(0)NPs formed on membranes and fragments of destroyed bacteria demonstrating altered morphology and smaller sizes in comparison with the initial nanocomposite that additionally enhances antimicrobial activity of such NPs.

    Abstract We measured the radiation tolerance of commercially available diamonds grown by the Chemical Vapor Deposition process by measuring the charge created by a 120 GeV hadron beam in a 50 μm pitch strip detector fabricated on each diamond sample before and after irradiation. We irradiated one group of samples with 70 MeV protons, a second group of samples with fast reactor neutrons (defined as energy greater than 0.1 MeV), and a third group of samples with 200 MeV pions, in steps, to (8.8±0.9) × 10
