“…The tensile strength is the maximum stress that the specimen bears before breaking. The tensile strength is related not only to the tensile stress, but also to the cross-sectional area [21]. The tensile strength of Qingdao Flower is 11.23Mpa and that of Marco Polo is 7.93Mpa.…”

“…The elastic modulus is a measure of the resistance of a sample to elastic deformation [21]. The elastic modulus of Qingdao Flower is 538.77Mpa and that of Marco Polo is 276.92Mpa, almost half of that of Qingdao Flower, indicating that Qingdao Flower has more strength, brittleness and strong resistance to tensile deformation, while Marco Polo has good elasticity while weak resistance to deformation.…”

So as to explore the mechanical properties of different varieties hop stems during the harvest period and resolve the problems of weak applicability in the cutting device of the hops harvester, this paper took the hops stems such two varieties as Qingdao Flower and Marco Polo as samples, and carried out tensile and cutting tests by using the universal testing machine. The tensile stress, tensile strength, elastic modulus and other mechanical indexes of the stems were measured by tensile test. The test results show that the stems of Marco Polo are thicker than those of Qingdao Flower. The tensile stress of Marco Polo is higher than that of Qingdao Flower and the tensile strength of Marco Polo is smaller than that of Qingdao Flower. The elastic modulus of Marco Polo is almost half of Qingdao Flower. The single factor test was carried out with the factors of cutting speed, cutting mode and water content. The single factor test shows that when cutting speed increase from 50mm / min to 250mm / min, the cutting strength of two stems first decrease and then tend to be stable. When the cutting modes are oblique cutting, transverse cutting and sliding cutting, the cutting strength decreases in turn. In the same cutting mode, the cutting strength of Qingdao Flower is greater than that of Marco Polo. With the increase of water content, the cutting strength of the two stems decreases significantly. On this basis, the orthogonal test was performed to determine the best cutting parameters. The orthogonal test shows that the primary and secondary order of the influence in test factors on cutting strength is water content, cutting mode and cutting speed. The effect of water content on Marco Polo cutting strength is extremely significant, and it has a significant effect on Qingdao Flower; The effect of cutting mode on the cutting strength of two kinds of stems is significant, while the effect of cutting speed on the cutting strength of two kinds of stems is not significant. The best cutting parameters of hops stems are fresh sample, speed of 100 mm / min, sliding cutting mode. The above analysis supplies a theoretical foundation for designation and optimization the cutting device.

“…However, studies have found that the modernization process in East Asia is different from that of Western countries in demographic and family patterns, such as, for example, the maintenance of the stem family. Stem family refers to a family structure wherein the intergenerational relationship is the main axis; it mainly consists of grandparents, a pair of married children and grandchildren who live together under the authority of the grandparents’ generation (usually grandfathers) (Li & Jiang, 1990). In Korea and Japan, although modernization has reduced family size, postponed marriage, and decreased the fertility rate, the process is much slower than in Western countries.…”

Using data from China Health and Retirement Longitudinal Study ( N = 3864), we examined the relationship between proximity to aging parents and depression among middle-aged (45–64 years) married individuals in China. Our study depicted and explained the declining coresident rate and showed a majority of adult children live separately from their parents. Children living in different households had higher levels of depression than coresident children, including those living adjacently. Furthermore, having a coresident spouse increased the levels of depression of sons living in an adjacent dwelling and in the same city, and reduced the levels of depression of daughters living farther away. More intergenerational economic support increased the levels of depression of daughters living in an adjacent dwelling. These findings may offer a reference for married adult children to reconstruct intergenerational proximity and adjust intergenerational relations.

The neuromorphic computing architecture is a promising artificial intelligence for implementing hierarchical processing, in‐memory computing, event‐driven operation and functional specialization in computing systems. However, current investigations mainly focus on unisensory processing without objective experience which is contrary to the flexible sensory learning capability in the human brain that can sense and process information according to the ever‐changing environment. For example, a dominant paradigm for reconfigurable bio‐learning features is the emotional experience. The neurotransmitter dopamine is released during arousal, influencing the vital brain functions involved in cognition, reward learning, movement and motivation. Here, the on‐demand configuration of a biorealistic synaptic connection based on a 2D CaTa2O7 (CTO) device is demonstrated that can be adaptively reconfigured for a reinforcement learning purpose by the light‐active resistive switching, which originated from the photon‐regulated metaplasticity. The low energy consumption of 12.4 fJ endows the reinforcement learning system with high power efficiency and reliability. Finally, in‐sensor computing with a CTO synapse is implemented with a filtering function to process digital data in a neuromorphic engineering manner. This work demonstrates the feasibility of 2D perovskite neuromorphic device with enhanced biological plausibility in the approaching post‐Moore era.
