Some quadrature methods for integration of ∫a^bf（x）e^iwg（x）dx for rapidly oscillatory functions are presented. These methods, based on the lower order remainders of Taylor expansion and followed the thoughts of Stetter [9], Iserles and NФrsett [5], are suitable for all w and the decay of the error can be increased arbitrarily in case that g＇（x）≠0 for x∈[a, b], and easy to be implemented and extended to the improper integration and the general case I[f]=∫a^b f（x）e^ig（w,x）dx.

In this paper, the effect of magnetic nanoparticles on the mechanical properties of a type-II superconductor is investigated both theoretically and numerically. Magnetic part of the pinning force associated with the interaction between a finite-size spheroidal magnetic inclusion and an Abrikosov vortex is calculated in the London approximation. It is found that the size and shape of magnetic nanoparticles result in different enhancements of vortex pinning in large-k type-II superconductors. Meanwhile, the screening current induced by a magnetic spheroid suffer the action of Lorentz force, which will lead to prestress in the superconductor, so further numerical calculations are needed to explore the interaction between the spheroidal magnetic particle and superconductor. The distribution of displacement, stress and strain in the superconductor are finally obtained. It is shown that different sizes and shapes of nanoparticles also can change the distributions of these quantities.

对于常规的雷达目标杂波图检测技术来说,每一个方位距离单元的背景功率水平估计是通过该分辨单元内连续扫描周期样本的递归更新来得到的,然而,当该分辨单元的连续扫描周期样本中存在大量干扰目标样本时,这种估计方法失效。对此,本文将空域恒虚警中的样本筛选技术借鉴到时域恒虚警中,设计了一种基于OTSU CCA的杂波图检测器,通过剔除连续扫描周期样本中可能存在的干扰目标样本来提高背景功率水平估计的准确性,进而提升杂波图的检测性能。

A new species of free-living marine nematode of the genus Daptonema Cobb, 1920 is described from the sublittoral sediment of the Jiaozhou Bay, Qingdao. Daptonema parabreviseta sp. *** characterized by having narrowed anterior end; small funnel-shaped buccal cavity; short cephalic setae;spicules with bulbiform proximal end and pointed distal end; gubercunalum tubular shape with a blunt dorsal apophysis. The female genital system presents a spacious postvulval sac. The new species closely resembles Daptonema brevisetosum Thanh & Gagarin, 2009. However, it differs from Daptonema brevisetosum by having relatively narrowed head(10 μm vs 20 μm); spicules with bulbiform proximal end and pointed distal end, not bifurcated at distal end. Female genital system with a spacious postvulval sac(vs absent).

Two new species of free-living marine nematodes of the genus Wieseria are described from the sublittoral sediment of the Jiaozhou Bay in Qingdao. Wieseria sinica sp. nov. is characterized by having short labial and cephalic setae in a backward direction; oblong amphidial foveas with double contour; arcuate spicules with alea; ring-like guberculum; and clavated tail. Wieseria tenuisa sp. nov. is characterized by its very large ＂a＂ value （133.6）, long labial setae in a forward direction; spicules with alea and hooked proximal end; rodlike gubernaculums; and relatively longer clavated tail （7.9 a.b.d, long）. It differs from Wieseria sinica sp. nov. mainly by the longer labial setae, slightly straight spicules with hooked proximal end, and its thinner body. Amended dichotomous key to male species of Wieseria is provided.

Modeling the complete geometry of general shapes from a single image is an ill-posed *** hints are often incorporated to resolve ambiguities and provide guidance during the modeling process. In this work, we present a novel interactive approach for extracting high-quality freeform shapes from a single image. This is inspired by the popular lofting technique in many CAD systems, and only requires minimal user input. Given an input image, the user only needs to sketch several projected cross sections, provide a"main axis", and specify some geometric relations. Our algorithm then automatically optimizes the common normal to the sections with respect to these constraints,and interpolates between the sections, resulting in a high-quality 3 D model that conforms to both the original image and the user input. The entire modeling session is efficient and intuitive. We demonstrate the effectiveness of our approach based on qualitative tests on a variety of images, and quantitative comparisons with the ground truth using synthetic images.
