Diabetic retinopathy (DR) has been reported to associate with gut microbiota alterations in murine models and thus “gut-retina-axis” proposed. However, the role of microbiome associated metabolism DR patients still need be elucidated. In this study, we collected fecal samples from 45 proliferative diabetic (PDR) 90 matched (1:2 according age, sex, duration diabetes) without (NDR) performed 16S ...

Active memristor elements, also called neuristors, are self-oscillating devices that very good approximations to biological neuronal functionality and crucial the development of low-power neuromorphic hardware. Materials showing conduction mechanisms depend superlinearly on temperature can lead negative differential resistance (NDR) regimes, which may further be engineered as self-oscillators. ...

The effectiveness of scientific development and research (NDR) in the agricultural sector depends on many factors, among which those that determine safety process itself play a special role. work examines requirements for ensuring safe harmless working conditions during development, indicating main legislative other normative legal acts relevant areas. Depending features NDR (fundamental, appli...

We evaluate the important two–loop matrix element 〈sγ|Q2|b〉 of the operator (c̄γPLb) (s̄γμPLb) contributing to the inclusive radiative decay B → Xsγ. The calculation is performed in the NDR scheme, by means of asymptotic expansions method. The result is given as a series in z ≡ m2c/m2b up to O(z6). We confirm the result of Greub, Hurth and Wyler obtained by a different method up to O(z3). Higher–...

− Tunnel diode I-V characteristics were measured (Figure 1.) − Mathematical manipulations were then carried out on the measured data to roughly estimate the function that could be used to describe the I-V characteristic curves. − First model was proposed and revised until a rough match between the measured data and simulated data was obtained. − The final model is a voltage-controlled current s...

Resistive Random-Access Memory Devices Neuromorphic devices are essential for beyond von-Neumann computing and Random Access Memories (RRAMs) the backbone it. In article number 2200744, Chandra Prakash colleagues show RRAM characteristics in a Bi12FeO20 system first time, together with negative differential resistance (NDR) write once read many (WORM) like simultaneously. It is hoped this could...

We present an exploratory calculation of the standard model ∆S = 2 matrix element relevant for indirect CP violation in K → ππ decays. The computation is performed with overlap fermions in the quenched approximation at β = 6.0 on a 16 3 × 32 lattice. The resulting bare matrix element is renormalized non-perturbatively. Our preliminary result is B NDR K (2 GeV) = 0.61(7), where the error does no...
