        The use of artificial intelligence (AI) service robots is on the rise. With service frontlines gradually shifting to human–robot interactions, the question of whether AI robots should be humanlike or machinelike has emerged. While many firms use robots that resemble humans in their appearance and actions, others use machinelike robots, assuming that very humanlike robots may lead to uncanny valley effects. There is no consensus on whether the anthropomorphism of service robots facilitates or constrains consumers’ experiences. To fill this gap, this article examines when and how service companies should use anthropomorphic AI service robots.

        The present studies explored the possibility of immobilizing phosphocholine (PC) liposomes on the surface of graphene oxide (GO) which was pre-adsorbed with two kinds of enzymes, horseradish peroxidase and glucose oxidase. The transmission electron microscope images showed that the PC liposomes adsorbed onto the GO surface kept integrity. By using 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS)-encapsulated liposomes, a one-step colorimetric assay for glucose was developed. In the presence of glucose, the GO nanocomposites catalyzed the cascade enzymatic reaction producing colorimetric signals directly. Under the optimal conditions, the GO nanocomposites produced linearly increased colorimetric signal with increased concentrations of glucose ranging from 50 to 500 μM. The detection limit was 33 μM. The GO nanocomposites also exhibited good selectivity for the detection of glucose and were able to detect glucose in human serum.

        Polypyrrole (PPy) decorated on reduced graphene oxide (rGO) films is successfully prepared with pyrrole (Py) monomers and rGO through one-step combining oxidation with polymerization reaction. Compared with the pure individual components, rGO/PPy compound turns out better electrochemical characteristics owing to the introduction of rGO sheets, which improves the specific surface area and the conductivity of composite material. When the amount of rGO is 10% of the total, the rGO/PPy compound delivers the best capacitance of 389.3 F g−1 at 1.0 A g−1 in a three-electrode system and 266.8 F g−1 at 0.25 A g−1 in the symmetric supercapacitor system. In addition, asymmetric device (rGO/PPy//AC) has been successfully fabricated using optimized rGO/PPy compound as positive electrode, activated carbon as negative electrode (AC) and 1 M Na2SO4 aqueous solution as electrolyte. The device obtains long cycle stability under the high-voltage region from 0 to 1.6 V, meanwhile displaying the satisfied energy density of 19.7 Wh kg−1 at 478.1 W kg−1. Besides, the rGO/PPy//AC device presents satisfactory rate capability and long life time.

        This research offers a concise retrospect on the South-South Coalition Strategy within multilateral trade negotiations of the GATT/WTO framework. The SSC strategy evolved in the postwar era, when the South integrated itself to demand for a New International Economic Order featured by fairness of outcome in international economic rules and activities. It then encountered an opponent trend of neo-liberalism, through which the South practically decided to sectoral exchange of economic interests with the North. From the new millennium onward, the South is learning to adopt a more issue-specific SSC strategy in trade negotiations. Although a question is arising for the future of SSC because of some emerging nations rising out from the traditional South group, a timely reflection from an evolutionary perspective would facilitate the understanding of the SSC strategy for weak countries to establish a fairer international economic order.

        Many advanced ground-based solar telescopes improve the spatial resolution of observation images using an adaptive optics (AO) system. As any AO correction remains only partial, it is necessary to use post-processing image reconstruction techniques such as speckle masking or shift-and-add (SAA) to reconstruct a high-spatial-resolution image from atmospherically degraded solar images. In the New Vacuum Solar Telescope (NVST), the spatial resolution in solar images is improved by frame selection and SAA. In order to overcome the burden of massive speckle data processing, we investigate the possibility of using the speckle reconstruction program in a real-time application at the telescope site. The code has been written in the C programming language and optimized for parallel processing in a multi-processor environment. We analyze the scalability of the code to identify possible bottlenecks, and we conclude that the presented code is capable of being run in real-time reconstruction applications at NVST and future large aperture solar telescopes if care is taken that the multi-processor environment has low latencies between the computation nodes.

        Recurring jets, which are jets ejected from the same site, are a peculiar type among various solar jet phenomena. We report such recurring jets ejecting from the same site above an active region on January 22, 2012 with high-resolution multi-wavelength observations from Solar Dynamics Observatory(SDO). We found that the recurring jets had velocities, lengths and lifetimes, but had similar directions. The visible brightening appeared at the jet base before each jet erupted. All the plasma produced by the recurring jets could not overcome the large coronal loops. It seemed that the plasma ejecting from the jet base was confined and guided by preexisting coronal loops, but their directions were not along the paths of the loops. Two of the jets formed crossing structures with the same preexisting filament. We also examined the photospheric magnetic field at the jet base, and observed a visible flux emergence, convergence and cancellation. The four recurring jets all were associated with the impulsive cancellation between two opposite polarities occurring at the jet base during each eruption. In addition, we suggest that the fluxes, flowing out of the active region, might supply the energy for the recurring jets by examining the SDO/Helioseismic and Magnetic Imager (HMI) successive images. The observational results support the magnetic reconnection model of jets.

        In Malaysia, figurative painting has increasingly become a means for artists to pose questions about presumptions of power and assumptions of history. The body, its potentially breached boundaries and defenses, forms an integral component of the battle for political influence. The degree of control over one's own and other people's bodies has become a measuring stick to determine the power of potential political leaders. Anxiety about boundaries and access to powerful bodies is intertwined with the questions of who has the right to hold power; the relevance of moral bodies and of what comprises an ideal self or selves. These questions are raised in intriguing ways in contemporary Malaysian art. While eschewing a direct take on current politics, Malaysian artists have increasingly turned to the body to address issues in Malaysian history, culture and the distribution of power. This paper will explore some works by three artists in particular, Wong Hoy Cheong, Nadiah Bamadhaj and Ahmad Fuad Osman use the figure to problematise dominant narratives in Malaysian history. Their work variously challenge political, racial and gender hierarchies and in so doing, reveal them as social constructions.

        In recent years, with the improvement of Internet infrastructure and the construction of a global logistics network, cross-border e-commerce has entered a stage of rapid development, and the scale of transactions has been expanding, becoming a vital force in the development of my country’ s foreign trade. As a major coastal economic province in my country, Guangdong Province has taken the lead in developing cross-border e-commerce by virtue of policy dividends, location advantages and its own sound foreign trade foundation, and has achieved remarkable achievements. Although the development space of cross-border e-commerce in Guangdong Province is good and the momentum is strong, as an emerging e-commerce model, its development is not smooth sailing, and there are still some hidden worries under the appearance of prosperity. From the perspective of healthy and sustainable development, Guangdong cross-border e-commerce should face up to its lack of independent brands in the international market, imperfect cross-border e-commerce logistics system, insufficient policy guidance strategies, imperfect payment system, and professional cross-border e-commerce talents. This paper will propose corresponding optimization measures based on these problems, in order to improve the development level of cross-border e-commerce in Guangdong Province, and provide certain inspiration for the development of cross-border e-commerce in other provinces in my country.

        Integrated circuits are the cornerstone of the development of information and communication technology industries in various countries, and to a large extent affect the development of the future technological industry revolution, and are known as “industrial food”. With the transfer of the global integrated circuit industry chain, emerging economies in East Asia represented by China and South Korea occupy a core position in the global integrated circuit trade. In recent years, although the scale of China’s integrated circuit trade has expanded rapidly, it has been in an unbalanced state for a long time, and the trade deficit is extremely high. The domestic demand for high-end integrated circuits can only be met by imports. The development of my country’s integrated circuit trade is large but not strong. Thanks to the financial support and preferential policies of the Korean government, in the 1980s, Korean integrated circuit companies took the lead in breaking through the international technology of memory integrated circuits. After that, the Korean government developed other integrated circuit products on this basis. Export of foreign exchange earning products. In order to measure the gap between China’s IC trade international competitiveness and South Korea more accurately. Next, a literature study is conducted on the comparative analysis of the development status of integrated circuit trade between China and South Korea. It was found that the development of South Korea’s integrated circuit industry was later than that of China, but the latter came ahead.
