TL;DR: In this article, the control problem for a class of stochastic nonlinear time-delay systems with uncertain output functions is studied, and a stabilization controller is explicitly constructed by applying the adding a power integrator method.
Abstract: This article studies the control problem for a class of stochastic nonlinear time-delay systems with uncertain output functions. Under the appropriate assumptions, a stabilization controller is explicitly constructed by applying the adding a power integrator method. Then, using the Lyapunov-Krasovskii functionals to address time-delay, it is proven that the designed controller can guarantee the closed-loop system to be globally asymptotically stable (GAS) in probability. Finally, two simulations show that the control strategy is effective and can be applied to the actual system.

TL;DR: In this article , the potential of Covalent Organic Folds (COFs) for use in various applications, particularly sensing with the nitrogen-rich analogs, was demonstrated.
Abstract: Covalent organic frameworks (COFs) have emerged as highly crystalline porous organic materials. Their potential has been demonstrated for use in various applications, particularly sensing with the nitrogen-rich analogs.

TL;DR: It is found that the availability of higher-order functions and function closures eliminates the need for ad hoc iterator classes, in addition to providing the other benefits of "mostly functional programming".
Abstract: The appearance of iterators in an object-oriented language appears to be inversely related to the power of the language's intrinsic control structures. Iterator classes are used for the sole purpose of enumerating the elements of an abstract collection class without revealing its implementation. We find that the availability of higher-order functions and function closures eliminates the need for these ad hoc iterator classes, in addition to providing the other benefits of "mostly functional programming". We examine a purely functional iteration protocol for the difficult task of comparing the collections of leaves on two non-isomorphic trees---the so-called "samefringe" problem---and find that its type signature requires recursive (cyclic) functional types. Although higher-order "member functions" and recursive (cyclic) functional types are unusual in object-oriented languages, they arise quite naturally and provide a satisfying programming style.

TL;DR: New bounds are obtained for the solution of the variance-gamma (VG) Stein equation that are of the correct form for approximations in terms of the Wasserstein and Kolmorogorov metrics for VG approximation of double Wiener-Ito integrals.
Abstract: We obtain new bounds for the solution of the variance-gamma (VG) Stein equation that are of the correct form for approximations in terms of the Wasserstein and Kolmorogorov metrics. These bounds hold for all parameters values of the four parameter VG class. As an application we obtain explicit Wasserstein and Kolmogorov distance error bounds in a six moment theorem for VG approximation of double Wiener-Ito integrals.
