Though many attacks have been published,no recovery attack better than exhaustive key search on full Grain v1 in the single key setting has been found yet. In this paper,new state recovery attacks on Grain v1 utilizing the weak normality order of the employed keystream output function in the cipher are proposed. These attacks have remarkable advantages in the offline time,online time and memory complexities,which are all better than exhaustive key search. The success probability of each new attack is 0.632. The proposed attack primarily depends on the order of weak normality of the employed keystream output function. This shows that the weak normality order should be carefully considered when designing the keystream output functions of Grain-like stream ciphers.展开更多

In this paper a generalized Roper-Suffridge extension operator F(z) ={f(Z1)+f'(z1)} on Reinhardt domain is defined. Some different conditions for Pj areestablished under which the operator preserves an almost spirallike mapping of type fl and order a and spirallike mapping of type β and order α, respectively. In particular, our results reduce to many well-known results.展开更多

The influence of Si content was studied by molecular mechanics, and an advantageous Si content was found. Various surfaces, promoters and active phases also played an important role in the interaction between the support surfaces and active phases, and some significant trends were found out. Quantum mechanics simulation was performed to study the possible effect of electrostatic interaction between the support and the active phase, upon which the calculations suggested that the existence of a favorable Si content was possible. The electronic effects of Co/Ni promoter and the intensity of Co/Mo/Ni/W/Li/AI/Si species bonded to the alumina support were also investigated by quantum mechanics, and it was found that the different electronic effects of Co and Ni might bring forth some obvious influences on the interaction between the support and the active phase. And the results of comparing the intensity of Co/Mo/Ni/W/Li/AI/Si species bonded to the support can also explain the different interaction intensity in various catalyst systems.展开更多

Those were reflected in the success of the G20 summit, the vigorous promotion of the"One Belt, One Road"(B&R) Initiative and the active promotion of international cooperation on development, which acquired positive response and general agreement from the international community and made special contributions to building a more just and reasonable international order.Those were also reflected in the active management of major power relations and sound responses to the changing situation in the surrounding area to create good external environment for domestic development. In addition, further expansion and defending of overseas interests set higher standards for Chinese diplomacy. Having been pushed by the era to the forefront, China is performing its responsibility as a major power in a peculiar way and will certainly make greater contributions to world peace and development.展开更多

Major reasons are the decline of US-led Western developed economies' global influence; US and other Western countries inaction or ineffective actions; power diffusion allowing non-state actors to intervene; a global governance short of needed rules; and mainstream economic theory's overemphasis on market roles. International disorder is a long-term process posing a potential threat to China's national interests. The situation challenges China to create an international economic and trade order, thereby shaping itself as prophet of global free trade, shaper of international economic and trade rules, and trendsetter for globalization.展开更多

Though international relations are constantly adjusted, the world is by no means more stable and orderly. International order reshaping triggered by the 2008 financial crisis is deepening, with chaos of various kinds popping up here and there. In the sociopolitical field, the"Trump phenomenon"and Brexit indicate serious weakening of the authority of traditional political systems and elites. In major country relations and international security, the world is witnessing the rise of emerging countries and the and fall of the West, fiercer US-Russia and Sino-US wrestling of strategic significance, and greater global and regional security risks. In global governance, while adjustment of UN-centered global governance is laboring along, national rivalries touch core issues, making global governance more urgent.展开更多

The babassu nut is approximately 8 to 15 cm long and 5 to 7 cm wide, with a slightly oval shape. The main commercial product extracted from babassu is the oil extracted from the kernels which represents 7% of the total weight of the fruit. The babassu nut nowadays is collected and shelled manually by women, this representing a problem of social order in the North/Northeastern region of Brazil. The objective of the present research was to develop an adequate shelling process for the nut, adding value to the raw material and taking better advantage of each of its components: epicarp, mesocarp, endocarp and the kernel itself, thus obtaining the shelled nut, composed of the endocarp and seed. The raw material had been dried by heat treatment; the epicarp and mesocarp were extracted using abrasive shelling equipment. The best position to cut the babassu nut was studied, in order to remove the kernel. The focus of the design was a simple, cheap process, easy to handle and agile to use, allowing the nuts to be cut with safety. The equipments were built based on the data which characterized the babassu nut, giving priority to the cost, adequacy for the region, ease in handling and safety. Considering a single work shift, a yield of 426.54% was obtained for the "nut cutter" equipment in relation to the productivity of the "nut-cracking women".展开更多
