Further Studies of the Cap Pushing Response in Honey Bees (Apis mellifera)

The Cap Pushing Response (CPR) is a free-flying technique used to study learning and memory in honey bees (Apis mellifera). The series of experiments outlined in this paper aimed to test whether honey bees exhibit the cognitive concept of “expectancy” utilizing the CPR in a weight differentiation paradigm. Five previous experiments in our laboratory have explored whether the concept of expectancy can account for honey bee performance and have all failed to support the cognitive interpretation. The first experiment examined if bees could differentiate between the two caps in the amount of force they used to push the cap and the distance the cap was pushed when the caps were presented one at a time. The second experiment explored cap weight preference by presenting bees with a choice between the two caps. The third and fourth experiments tested the bee’s ability to expect reward or punishment based on cap weight. Results revealed that bees were found to have a strong preference for the light cap and therefore were not able to expect reward or punishment based on cap weight. These experiments contribute to the debate on whether bees have “cognitive” representations and continue to support the behaviorist interpretation.

Collaborative Pushing and Grasping of Tightly Stacked Objects via Deep Reinforcement Learning

Directly grasping the tightly stacked objects may cause collisions and result in failures,degenerating the functionality of robotic arms.Inspired by the observation that first pushing objects to a state of mutual separation and then grasping them individually can effectively increase the success rate,we devise a novel deep Q-learning framework to achieve collaborative pushing and grasping.Specifically,an efficient non-maximum suppression policy(PolicyNMS)is proposed to dynamically evaluate pushing and grasping actions by enforcing a suppression constraint on unreasonable actions.Moreover,a novel data-driven pushing reward network called PR-Net is designed to effectively assess the degree of separation or aggregation between objects.To benchmark the proposed method,we establish a dataset containing common household items dataset(CHID)in both simulation and real scenarios.Although trained using simulation data only,experiment results validate that our method generalizes well to real scenarios and achieves a 97%grasp success rate at a fast speed for object separation in the real-world environment.

Theoretical and experimental study on frequency pushing effect of magnetron

The applications of magnetrons are greatly limited because of the poor output spectrum of the free-running magnetron.Currently, one of the best ways to solve this problem is injection locking. However, the injection locking theory which is widely used nowadays is based on the simplified oscillator, which does not include the frequency pushing effect of the magnetron. In this paper, the theory of injection locking magnetrons with frequency pushing effect is systematically studied.Analytical analysis shows that the locking bandwidth turns larger with the consideration of the pushing parameter(α), and the increase of locking bandwidth is expanded with α increasing. Experimental results show that the locking bandwidth is expanded by 0.3 MHz, 1 MHz, and 1.6 MHz compared with the locking bandwidth from the conventional locking theory under an injection ratio(ρ) of 0.05, 0.075, and 0.1, respectively. This research provides a more accurate prediction of the properties of the injection-locked magnetron.

Simulation of Fiber Pushing-out Test

The stress distribution on the failure progress of fiber pushed-out test was studied. A numerical program, developed by meso-damage mechanics, was adopted to simulate the whole failure process of interface debonding and fiber pushing out. From the simulation, it can be concluded that, the interfacial stress on load side and support side is larger than other portions. Simultaneously, the shear stress in both sides becomes larger when thickness of sample reduces. Furthermore, when the diameter of fiber increases, the shear stress on load side is getting larger but in support side it is diminishing. On the other hand, changes of the support hole’s diameter only affect the interfacial shear stress on the support side.

Study on Particle Pushing in Front of Growing Interface During Soldification

For in situ composite materials, the interaction between the second phase particles and the solidification interface attracts more attentions of people, for concerning the final distribution of the particles on the matrix. With the conception of the local solidification time, a kinematics mechanism of particle pushing into the crystal boundary during the solidification process was assumed. Through the analysis of forces acted on the particle in front of the solid/liquid interface the critical velocity criterion for the particles pushing was given. The calculation results show when the growth rate of the interface V is less than or equals to the critical velocity V C , the particles on the solid/liquid interface is pushed into the boundary region of cellular crystals, where they are distributed as a chain like straight, which forms a particle strengthened in situ composite materials.

Global Timekeepers Push Pause on the Leap Second

Half a century—plus 37 seconds—after it was first introduced to the world,the leap second has been scheduled for retirement.On 18 November 2022 at the General Conference on Weights and Measures(CGPM)outside of Paris,France,representatives of governments around the globe decided that astronomical time(known as UT1),which is determined by Earth’s rotation,will be allowed to diverge by more than one second from Coordinated Universal Time(UTC),which is based on the steady ticking of atomic clocks[1].While the change—not to be implemented until 2035—will go unnoticed by most people,it promises to simplify the timekeeping vital to services provided by a wide range of global industries,including transportation,defense,and finance.
