Regularized Wasserstein Means for Aligning Distributional Data

We propose to align distributional data from the perspective of Wasserstein means. We raise the problem of regularizing Wasserstein means and propose several terms tailored to tackle different problems. Our formulation is based on the variational transportation to distribute a sparse discrete measure into the target domain. The resulting sparse representation well captures the desired property of the domain while reducing the mapping cost. We demonstrate the scalability and robustness of our method with examples in domain adaptation, point set registration, and skeleton layout

Adaptive Network Coding for Scheduling Real-time Traffic with Hard Deadlines

We study adaptive network coding (NC) for scheduling real-time traffic over a single-hop wireless network. To meet the hard deadlines of real-time traffic, it is critical to strike a balance between maximizing the throughput and minimizing the risk that the entire block of coded packets may not be decodable by the deadline. Thus motivated, we explore adaptive NC, where the block size is adapted based on the remaining time to the deadline, by casting this sequential block size adaptation problem as a finite-horizon Markov decision process. One interesting finding is that the optimal block size and its corresponding action space monotonically decrease as the deadline approaches, and the optimal block size is bounded by the "greedy" block size. These unique structures make it possible to narrow down the search space of dynamic programming, building on which we develop a monotonicity-based backward induction algorithm (MBIA) that can solve for the optimal block size in polynomial time. Since channel erasure probabilities would be time-varying in a mobile network, we further develop a joint real-time scheduling and channel learning scheme with adaptive NC that can adapt to channel dynamics. We also generalize the analysis to multiple flows with hard deadlines and long-term delivery ratio constraints, devise a low-complexity online scheduling algorithm integrated with the MBIA, and then establish its asymptotical throughput-optimality. In addition to analysis and simulation results, we perform high fidelity wireless emulation tests with real radio transmissions to demonstrate the feasibility of the MBIA in finding the optimal block size in real time.Comment: 11 pages, 13 figure

A Self-Adaptive Chaos Particle Swarm Optimization Algorithm

As a new evolutionary algorithm, particle swarm optimization (PSO) achieves integrated evolution through the information between the individuals. All the particles have the ability to adjust their own speed and remember the optimal positions they have experienced. This algorithm has solved many practical engineering problems and achieved better optimization effect. However, PSO can easily get trapped in local extremum, making it fail to get the global optimal solution and reducing its convergence speed. To settle these deficiencies, this paper has proposed an adaptive chaos particle swarm optimization (ACPSO) based on the idea of chaos optimization after analyzing the basic principles of PSO. This algorithm can improve the population diversity and the ergodicity of particle search through the property of chaos; adjust the inertia weight according to the premature convergence of the population and the individual fitness; consider the global optimization and local optimization; effectively avoid premature convergence and improve algorithm efficiency. The experimental simulation has verified its effectiveness and superiority

Making Art Involve in the Paradigm of Ecological Landscape Construction in Ancient Villages—Taking Cai Fan and Longtan Ancient Village in Taihu as an Example

The ancient residences of Cai fan Ancient Village and Longtan Village in Taihu County of Anqing City are historical and traditional villages with common regional cultural background. They have strong cultural characteristics of Huizhou and foreign architectural features. The overall architectural style of the ancient villages in Anqing area is combined with the topography, landforms and landscapes of the area where it is located, forming a unique architectural style. In addition, during the Ming and Qing Dynasties, the strong economic support of Huizhou merchants and the cultural education became increasingly prosperous. Developed, and even after the Huizhou merchants returned to their hometowns, they conceived and built houses with elegant, literary and detached mentality, which made the cultural environment and ecological landscape of Anqing ancient villages richer and the village landscape more prominent. The ancient village of Anqing is a typical representative of the regional culture of the southwest and has important historical and cultural values

Cicadulina (Idyia) fijiensis Linnavuori (Hemiptera: Cicadellidae: Deltocephalinae: Macrostelini), a new leafhopper record for China

Cicadulina (Idyia) fijiensis Linnavuori, bisher nur aus dem paszifischen Raum und aus Nepal bekannt, wird hier erstmals für China angegeben. Neue intraspezfische Variabilität in den männlichen Genitalien der Art und von C. bipunctata (Melichar) werden diskutiert, einschließlich der Ähnlichkeiten einer Population dieser Art mit der pazifischen Art C. bimaculata (Evans). Abbildungen und ein Schlüssel zur Trennung der beiden chinesischen Arten weren vorgestellt.Cicadulina (Idyia) fijiensis Linnavuori, formally known only from the Pacific and Nepal, is reported for the first time from China. New intraspecific variation in the male genitalia of this species and C. bipunctata (Melichar) is discussed, including the similarity of a population of the latter species to the Pacific C. bimaculata (Evans).

Morphology and ultrastructure of salivary glands of male treehopper Tricentrus brunneus Funkhouser (Hemiptera: Membracoidea)

The salivary glands of male treehopper Tricentrus brunneus Funkhouser comprise a pair of acinous principal glands each with an anterior lobe and a posterior lobe; a pair of elbow-shaped accessory glands. Every accessory gland connects with the principal gland via a thin accessory salivary duct. The anterior lobe contains three types of acini (I, II and III), whereas the posterior lobe possesses only one type of acinus (IV). Two efferent salivary ducts fuse into a common salivary duct. Different acinis cells are filled with secretory granules that are distinct in size, number, shape and electron-density, indicating a maturation process before secreted. Infoldings in different acini suggest dilution of substances before being secreted. The presence of microvilli in acinus IV and the accessory gland duct possibly indicates the undergoing maturation of secretions. Electron-dense fine granules existed in the accessory gland cells, possibly related to virus transmission
