Pneumatic artificial muscles(PAMs)usually exhibit strong hysteresis nonlinearity and time-varying features that bring PAMs modeling and control difficulties.To characterize the hysteresis relation between PAMs\'displacement and fluid pressure,a long sho
Harvesting energy from ambient environment has been considered as a promising strategy for driving portable electronic devices in a sustainable way.A wind driven triboelectric-electromagnetic hybrid nanogenerator has been fabricated to convert wind energy
Patterns resulted from modulation instability are ubiquitous and have been extensively studied in optics and Bose-Einstein con-densates.However,these patterns have not been realized in ultracold Fermi gases,although there has been considerable theo-retica
Nucleon momentum distribution (NMD),particularly its high-momentum components,is essential for understanding the nucleon-nucleon (NN) correlations in nuclei.Herein,we develop the studies of NMD of 56Fe from the axially deformed relativistic mean-field (RM
The quasi-zero-stiffness(QZS)vibration isolation has been proven to be an effective way to isolate low-frequency vibration.However,most of the existing QZS isolators are space-consuming,which could not be employed in the space-limited cir-cumstances.In th
The recently discovered kagome metal series AV3Sb5(A=K,Rb,Cs)exhibits topologically nontrivial band structures,chiral charge order and superconductivity,presenting a unique platform for realizing exotic electronic states.The nature of the super-conducting
Dear editor,rnK2 is a secure and high-performance stream cipher and has been standardized by ISO/IEC 18033-4.The MASHA stream cipher is a successor of K2 with integrated MAC functionality proposed in 2011.Based on optimizing the guess and determination pr
Chaotic inflation is inconsistent with the observational constraint at 68％CL.Here,we show that the enhancement mechanism with a peak function in the noncanonical kinetic term not only helps the chaotic model V(φ)=V0φ1/3 satisfy the observational constrain
Nonlinear plasmonic metasurfaces are compatible with complementary metal oxide semiconductor technology and highly promising for on-chip optical switching and modulations and nanoscale frequency conversions.However,the low nonlinear-optical response of me
我1934年9月出生于江苏昆山一个农民家庭.回想起来,从离开家乡奔赴东北到退休离开岗位,我在人民邮电岗位上工作了43年,并亲历了抗美援朝战争.1969年,我正式加入光荣伟大的中国共产党.rn1938年,中国正经历着日本帝国主义的侵略,中国人民遭受了残酷迫害,我的父亲也因此失去了生命.1949年新中国成立,15岁的我在昆山农村第一次感受到“站起来”的自豪,然而此时,一场战争正悄然逼近中国东北,威胁着中国人民.
