Two-dimensional (2D) noble-metal dichalcogenides 1, 2 have emerged as a new platform for the realization of versatile flat optics with a considerable degree of miniaturization. However, light field manipulation at the atomic scale is widely considered unattainable since the vanishing thickness and intrinsic losses of 2D materials completely suppress both resonances and phase accumulation effects. Empowered by conventionally perceived adverse effects of intrinsic losses, we show that the structured PtSe2 films integrated with a uniform substrate can regulate nontrivial singular phase and realize atomic-thick meta-optics in the presence of topological darkness 3, 4. We experimentally demonstrate a series of atomic-thick binary meta-optics that allows angle-robust and high unit-thickness diffraction efficiency of 0.96%/nm in visible frequencies, given its thickness of merely 4.3 nm. Our results unlock the potential of a new class of 2D flat optics for light field manipulation at an atomic thickness. Copyright © 2019, The Authors. All rights reserved.

This work applies the LQ control framework to the class of quasi-polynomial and Lotka-Volterra systems through the linearized version of their nonlinear system model. The primary aim is to globally stabilize the original system with a suboptimal LQ state feedback by means of a well-known entropy-like Lyapunov function that is related to the diagonal stability of linear systems. This aim can only be reached in the case when the quasi-monomial composition matrix is invertible. In the rank-deficient case only the local stabilization of the system is possible with an LQ controller that is designed using the locally linearized model of the closed-loop system model. © 2016

Many real life networks present diameter logarithmic with the number of nodes and degree distribution that follow power law. Often these networks have also a modular and self-similar feature and usually associated with topological restrictions-their clustering is low, even zero, and they are almost non-planar. In the paper, we propose a generalized self-similarity growing network model. As the construction is deterministic, we can capture exact analytic expressions for relevant properties of the model including average degree, clustering coefficient, degree distribution, diameter, the number of leaves of every maximumleaf spanning tree. We make a conclusion that it is scale-free and small-world.

In bioinformatics research area, many scholars from physiology, physics, mahtematics, computer science and other discliplines probe in the profound of genetic engineering via integrating expermential researchers and theoretical analysis,and try exposes the nature of biological genetic information. We investigate connections between power law degree distribution and cumulative degree distributions of scale-free network models First, we enumerate several classical deterministic network models with scale-free topological structure and analysis the connections between degree distribution and cumulative degree distributions. Second, we apply the random network models to state the connection between power law degree distribution and cumulative degree distributions. Finally, as a further research step, we probe the reasons that make the gaps between them.

We present an example of deterministic network models in an iterative fashion. The network has small-world effect, scale-free topology and high degree of tolerance against random failure. We propose some new parameters for this model in order to further discuss the damage rate,such as collapse-rank, fragile-rank, as well as the edge-cumulative distribution and d-degree cumulative distribution, neighbor degree-average, attracting number. In addition, we compute these parameters for the model.

The dynamical phenomena of complex networks are not easy to model and to characterize by current methods of mathematics. Newman, Baraba′si and Watts pointed out the direction of researching complex networks by graph theory, which was successfully applied in current investigation of complex networks, and Newman's network-based methods have been applied to a variety of fields. Some well-known and new methods of mathematics are provided in this article, associated with construction and problems on scale-free models from real networks.

A logistical network is related with traffic networks, information networks, multiple goods networks in general. In the view of mathematics, a logistics is the compound result of three or more other networks. We design random multiple models by network operations based on stable transport networks, and measure dynamic differential equations, degree distribution, cumulative distribution of the models.

An improved diagnosis method of technological systems is proposed in this paper that is based on their qualitative colored Petri-net model (Leitold et al. 2014). The proposed diagnosis method can be used when more than one fault occur in the system and if the fault evolves during the operation of the system. In order to make the diagnosis of complex process systems computationally feasible, a structural decomposition method is introduced to reduce the size of their occurrence graphs and to make the diagnosis easier. The proposed methods are illustrated on examples.
