China's economic growth pushed by domestic demand and relevant measures

By contrast to a slowdown in the world economy, China kept up a rapid growth rate, a relatively high quality of growth and low inflation for the year 2001. This is mainly due to the result of proactive fiscal policies that the Chinese Government adopted to stimulate domestic demand. Domestic demand can be divided into investment demand and consumption demand,

Failure characterization of fully grouted rock bolts under triaxial testing

Confining stresses serve as a pivotal determinant in shaping the behavior of grouted rock bolts.Nonetheless,prior investigations have oversimplified the three-dimensional stress state,primarily assuming hydrostatic stress conditions.Under these conditions,it is assumed that the intermediate principal stress(σ_(2))equals the minimum principal stress(σ_(3)).This assumption overlooks the potential variations in magnitudes of in situ stress conditions along all three directions near an underground opening where a rock bolt is installed.In this study,a series of push tests was meticulously conducted under triaxial conditions.These tests involved applying non-uniform confining stresses(σ_(2)≠σ_(3))to cubic specimens,aiming to unveil the previously overlooked influence of intermediate principal stresses on the strength properties of rock bolts.The results show that as the confining stresses increase from zero to higher levels,the pre-failure behavior changes from linear to nonlinear forms,resulting in an increase in initial stiffness from 2.08 kN/mm to 32.51 kN/mm.The load-displacement curves further illuminate distinct post-failure behavior at elevated levels of confining stresses,characterized by enhanced stiffness.Notably,the peak load capacity ranged from 27.9 kN to 46.5 kN as confining stresses advanced from σ_(2)=σ_(3)=0 to σ_(2)=20 MPa and σ_(3)=10 MPa.Additionally,the outcomes highlight an influence of confining stress on the lateral deformation of samples.Lower levels of confinement prompt overall dilation in lateral deformation,while higher confinements maintain a state of shrinkage.Furthermore,diverse failure modes have been identified,intricately tied to the arrangement of confining stresses.Lower confinements tend to induce a splitting mode of failure,whereas higher loads bring about a shift towards a pure interfacial shear-off and shear-crushed failure mechanism.

Assessing the energy release characteristics during the middle detonation reaction stage of aluminized explosives

Afterburning behind the detonation front of an aluminized explosive releases energy on the millisecond timescale,which prolong the release of detonation energy and the energy release at different stages also shows significant differences.However,at present,there are few effective methods for evaluating the energy release characteristics of the middle reaction stage of such explosives,which can have a duration of tens to hundreds of microseconds.The present work demonstrates an approach to assessing the midstage of an aluminized explosive detonation based on a water push test employing a high degree of confinement.In this method,the explosive is contained in a steel cylinder having one end closed that is installed at the bottom of a transparent water tank.Upon detonation,the gaseous products expand in one direction while forcing water ahead of them.The resulting underwater shock wave and the interface between the gas phase products and the water are tracked using an ultra-high-speed framing and streak camera.The shock wave velocity in water and the expansion work performed by the gaseous detonation products were calculated to assess the energy release characteristics of aluminized explosives such as CL-20 and RDX in the middle stage of the detonation reaction.During the middle stage of the detonation process of these aluminized explosives,the aluminum reaction reduced the attenuation of shock waves and increased the work performed by gas phase products.A higher aluminum content increased the energy output while the presence of oxidants slowed the energy release rate.This work demonstrates an effective means of evaluating the performance of aluminized explosives.

How to Break Through the“Third Wall”of Cosmetics Science Communication?

Stepping into 2024,with the increase of“knowledge density”of Chinese consumers,the“marketing discourse”of beauty brands has shifted from a perceptual“word game”to a serious“scientific argument”.Perhaps some brands will shout“good times are coming”.But the reality is that communication turns out to be the weakest part between brand technology and consumers.Under the condition of technological“involution”and fragmented media ecology,the trust cost of brand communication is being pushed to a new high,and the efficiency of communication is rapidly decreasing.Many enterprises are trapped in the dilemma of content that is difficult to be expressed and communicated.

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.

基因组测序成本将再次降低

The race is on again in DNA sequencing.In what has been described as“the year of the big shake-up”[1],a wave of new competitors entered the market in 2022,challenging industry leader Illumina(San Diego,CA,USA).New systems from both Illumina and emerging rivals are now poised to push costs down—closing in on the oft-cited goal of 100 USD per genome.The prospect of more economical sequencing is big news because the spectacular cost reductions that helped fuel the genomics revolution in previous decades have stalled in recent years(Fig.1).Lower costs will make sequencing affordable for a broader array of users and applications in fields such as biology,biotechnology,and medicine.

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.

Study on a Bowl-based Mechanism for Transplanting Potted Strawberry Seedlings
