Aiming at the problem of insufficient security image encryption technology, a secure algorithm using chaos-based block permutation and weighted bit planes chain diffusion is proposed, which based on variant structure classical permutation-diffusion. During phase, operations dividing an into sub-block, scrambling, rotation inversion, negative-positive transformation, color component shuffling are performed sequentially with chaotic sequences plaintext association. In stage, different...
This paper proposes a dynamic RNA-encoded color image encryption scheme based on chain feedback structure. Firstly, the pure is decomposed into red, green, and blue components, then chaotic sequence plaintext association introduced to encrypt red component. Secondly, intermediate ciphertext obtained by diffusion after bit-level permutation, RNA encoding, operation rules, decoding. Finally, enhance security of cryptosystem, green components are repeatedly encrypted using mechanism associated...
The BES experiment at the Beijing electron-positron collider has observed ξ(2230) signal in π+π−, K+K−, K0SK0S, and p¯p final states with 4.6σ, 4.1σ, 4.0σ, 3.8σ statistical significances, respectively. new observations of two nonstrange decay modes ξ→π+π− are important evidence for glueball interpretation ξ(2230).Received 30 October 1995DOI:https://doi.org/10.1103/PhysRevLett.76.3502©1996 American Physical Society
In this paper, we theoretically simulate the dynamic evolution of plasma from interaction between a nanosecond pulsed laser and aluminum targets. The self-luminous image plume during loading process was experimentally obtained using high-speed photography. Theoretical experimental results demonstrated that shielding effect lateral expansion have significant on plume. It will affect laser–target coupling further plumes. detonation wave contained in early stage laser-induced directly affects...
The Beijing Spectrometer (BES) experiment has observed purely leptonic decays of the ${D}_{s}$ meson in reaction ${e}^{+}{e}^{\ensuremath{-}}\ensuremath{\rightarrow}{D}_{s}^{+}{D}_{s}^{\ensuremath{-}}$ at a c.m. energy 4.03 GeV. Three events are which one hadronically to $\ensuremath{\varphi}\ensuremath{\pi}$, ${\overline{K}}^{*0}K$, or ${\overline{K}}^{0}K$, and other leptonically $\ensuremath{\mu}{\ensuremath{\nu}}_{\ensuremath{\mu}}$...
The data on $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\gamma}{K}^{+}{K}^{\ensuremath{-}}$ from the BES experiment at Beijing electron-positron collider have been analyzed. We find two resonances in 1.7 GeV region which were identified as ${f}_{J}(1710)$: a scalar with mass $1781\ifmmode\pm\else\textpm\fi{}{8}_{\ensuremath{-}31}^{+10}(\mathrm{MeV})$ and width $85\ifmmode\pm\else\textpm\fi{}{24}_{\ensuremath{-}19}^{+22}(\mathrm{MeV})$, tensor...
The cross section for e+e−→ρπ has been measured by the BES detector at BEPC center-of-mass energies covering a 40 MeV interval spanning Jψ resonance. data are used to search vector gluonium state hypothesized Brodsky, Lepage, and Tuan as an explanation of ρπ puzzle in charmonium physics. shape is compatible with that total hadronic section. No distortions indicating presence glueball seen.Received 19 October 1995DOI:https://doi.org/10.1103/PhysRevD.54.1221©1996 American Physical Society
Purely leptonic decays of the charged D meson have been studied using reaction e+e−→D∗+D− at a center mass energy 4.03 GeV. A search was performed for D→μνμ recoiling against D0 or D+ which had reconstructed from its hadronic decay products. single event candidate found in e+e−→D∗+D−, where D∗+→π+D0 with D0→K−π+, and D− decaying via D−→μ−ν̄μ. This yields branching fraction value B(D→μνμ)=0.08−0.05−0.02+0.16+0.05%, corresponding pseudoscalar constant fD=300−150−40+180+80 MeV.

The absolute inclusive branching fraction of D+s→φX+ has been measured from data collected by the BES detector at a center-of-mass energy 4.03 GeV, corresponding to an integrated luminosity 22.3 pb−1. At this energy, direct pair production e+e−→D+sD−s observed.
