This study examines an optimal inventory strategy when a retailer markets a product at different selling prices through a dual-channel supply chain, comprising an online channel and an offiine channel. Using the operating pattern of the offiine-to-online （020） business model, we develop a partial robust optimization （PRO） model. Then, we provide a closed-form solution when only the mean and standard deviation of the online channel demand distribution is known and the offiine channel demand follows a uniform distribution （partial robust）. Specifically, owing to the good structural properties of the solution, we obtain a heuristic ordering formula for the general distribution case （i.e., the offiine channel demand follows a general distribution）. In addition, a series of numerical experiments prove the rationality of our conjecture. Moreover, after comparing our solution with other possible policies, we conclude that the PRO approach improves the performance of incorporating the internet into an existing supply chain and, thus, is able to adjust the level of conservativeness of the solution. Finally, in a degenerated situation, we compare our PRO approach with a combination of information approach. The results show that the PRO approach has more ＂robust＂ performance. As a result, a reasonable trade-off between robustness and performance is achieved.

为提高小曲白酒中乙酸乙酯的含量,以大曲中分离的一株产酯能力较强的扣囊复膜酵母M1为出发菌株,将其制备为麸曲(M1麸曲)并用于小曲白酒酿造,分析M1麸曲强化发酵对小曲白酒挥发性风味组分的影响。结果表明:M1麸曲最佳培养条件为:水分质量分数40%、培养温度28℃、麸皮初始酸度6 mmol/100 g、培养时间48 h;酿造实验结果显示,添加M1麸曲显著提高了实验组(K组)乙酸和乙酸乙酯的含量(P<0.05),极显著降低了异丁醇和异戊醇的含量(P<0.01);通过对微生物群落结构的分析表明,对照组和K组酒醅的微生物群落演替规律存在差异,K组扣囊复膜酵母属和魏斯氏菌属相对丰度增加;同时通过PICRUSt2功能预测分析,验证了K组参与乙酸和乙酸乙酯代谢的酶丰度更高。通过麸曲为介质将扣囊复膜酵母M1应用到小曲发酵可有效提高小曲白酒乙酸乙酯的含量,对提高小曲白酒质量具有一定参考意义。

A piezoelectric platform using function module actuator is presented to achieve nano-positioning and high frequency scanning in large working range. A function module actuator is designed to produce a pair of orthogonal bending deformations and a longitudinal deformation through partition exciting. The bending deformations are used to actuate the planar motion,while the longitudinal deformation is utilized to dynamically adjust the driving force and broaden the scanning frequency. The dynamic model of the platform system is developed. The open-loop performances of a prototype are first tested: a scan frequency of 308 Hz in a scanning range of 3.368 μm×3.396 μm is measured in direct actuation mode,and the displacement resolution is measured to be 16 nm;maximum speed is measured to be 3.38 mm s^-1 in the inertial actuation mode. Furthermore,the closedloop experiments are carried out and a switching strategy is proposed to obtain the switching of the inertial and direct actuation modes automatically;the platform achieves the scanning with frequency of 300 Hz at the set position.

Based on archival materials, this article examines Land Reform and Collectivization in 1940s and 1950s from the viewpoint of rural-urban relations. It argues that there were various strong ties between rural society and urban society in traditional China. However, the programs of Land Reform and Collectivization cut off these ties and made it impossible for Chinese people to be ＂amphibious＂ as they were previously. This fundamental change reshaped China＇s rural-urban relations, making rural society and urban society two separate spheres. The new rural-urban relations lasted all the way down to the present without being overhauled.

It is an emerging challenge for robots to achieve non-destructive pick-and-place manipulation for delicate objects under low normal preload, i.e., critical-contact manipulation. The prominent on-off controllable property of the gecko-inspired microwedge adhesive makes critical-contact manipulation possible for robotic end effectors. However, it is difficult for end effectors to actuate the micron-scale microwedge adhesive and detect the adhesion state. In this paper, a gecko-inspired adhesive robotic end effector for critical-contact manipulation is proposed, which consists of a half-scissor variable-scale actuator, a 3-axis high-sensitivity isotropic flexible capacitive tactile sensor, and the microwedge adhesive. The half-scissor variable-scale actuator is designed to provide pure large shear loading for the microwedge adhesive at micronscale displacement by merely controlling the normal macro-scale displacement of the actuator. Besides, the3-axis high-sensitivity isotropic flexible capacitive tactile sensor is designed for accurate detection of multiaxis contact forces and the adhesion state between the adhesive and objects to ensure the success of the critical-contact manipulation. The sensor can sense the shear and normal forces by detecting variations of the overlap and distance between electrodes, while the design of the finger-like electrodes improves the sensitivity. In addition, a set of experiments on manipulating objects are implemented and the results show that the proposed robotic end effector can provide pure large shear loading for the microwedge adhesive at micron-scale displacement and can detect the adhesion state between the microwedge adhesive and objects accurately to stably grasp delicate objects in critical-contact condition.
