We present weakly interacting massive particles(WIMPs)search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX),based on the data from both CDEX-1B and CDEX-10 stages.In the nonrela-tivistic effective field theory approach,both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90％confidence level(C.L.)and improve over the current bounds in the low mx region.In the chiral effective field theory approach,data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90％C.L.We for the first time extended the limit to the mx＜6 GeV/c2 region.

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

The pairing symmetry of the superconducting order parameter contains key information about the pairing mechanism of the superconductor.For conventional superconductors,whose pairing is usually induced by the electron-phonon interaction,the pairing symmetr
Disulfide (DSF) has been proved good anti-tumor effect and even better with coadministration of Cu2+.In this work,we report the use of hyaluronic acid (HA) based materials to construct vectors for the delivery of both DSF and Cu2+.HA was firstly modified
