A novel scheme for generating optical chaos is proposed and experimentally demonstrated,which supports to simultaneously produce two low-correlation chaotic signals with wideband spectrum and suppressed time-delay-signature(TDS).In the proposed scheme,we use the output of an external-cavity semiconductor laser(ECSL)as the driving signal of a phase modulator to modulate the output of a CW *** the phase-modulated continuous-wave(CW)light is split into two parts,one is injected back into the ECSL that outputs one chaotic signal,while the other part is passed through a dispersion module for generating another chaotic signal *** experimental results prove that the proposed scheme has three ***,it can improve the bandwidth of ECSL-based chaos by several times,and simultaneously generate another wideband flat-spectrum chaotic ***,the undesired TDS characteristics of the simultaneously-generated chaotic signals can be efficiently suppressed to an indistinguishable level within a wide parameter range,as such the complexities of the chaotic signals are considerably ***,the correlation coefficient between these two simultaneously-generated chaotic signals is smaller than *** proposed scheme provides an attractive solution for parallel multiple chaos generation,and shows great potential for multiple channel chaos communications and multiple random bit generations.

Rapid advances in flexible and wearable smart textiles demand low-cost,high-energy/power-density fiber-shaped supercapacitors(FSCs).The performance of FSCs is determined by the fabrication and assembly of fiber-shaped electrodes(FSEs),where an active charge-storage material is always clad around flexible charge transmission current *** by the tissue structure of natural bamboo,wherein parenchyma cells(PCs)that store nutrients are clad around bamboo fibers(BFs),we propose a strategy for converting bamboo cells into FSEs using conductive BFs and activated PCs as current collectors and active materials,*** assembled electrode has a high specific capacitance of 1454 mF cm^(−2) at 0.64 mA cm^(−2).A solid-state FSC with a pair of bamboo-structured electrodes exhibited a substantially high energy *** mechanical flexibility enabled the knitting of wearable wristbands to drive ultra-small voltmeter *** lightweight,low cost,and high-energy-density bamboostructured FSC could enable numerous smart textile applications.

Whether habit stimulation is effective in DOC patient arousal has not been reported. In this paper, we analyzed the responses of DOC patients to habit stimulation. Nineteen DOC patients with alcohol consumption or smoking habits were recruited and 64-channel EEG signals were acquired both at the resting state and at three stimulation states. Wavelet transformation and nonlinear dynamics were used to extract the features of EEG signals and four brain lobes were selected to investigate the degree of EEG response to habit stimulation. Results showed that the highest degree of EEG response was from the callname stimulation, followed by habit and music stimulations. Significant differences in EEG wavelet energy and response coefficient were found both between habit and music stimulation, and between habit and call-name stimulation. These findings prove that habit stimulation induces relatively more intense EEG responses in DOC patients than music stimulation, suggesting that it may be a relevant additional method for eliciting patient arousal.

Background Primary systemic light chain amyloidosis （AL） is a rare plasma cell disease,our purpose was to analyze the immunophenotypic characteristics of the plasma cells in bone marrow in AL patients,and explore whether the detection of abnormal plasma cell clones in bone marrow by flow cytometry （FCM） could be used as an important indicator of AL *** Fresh bone marrow samples were collected from 51 AL,21 multiple myeloma （MM）,and 5 Waldenstr（o）m＇s macroglobulinemia （WM） *** immunophenotype of bone marrow cells were analyzed and compared by FCM using a panel of antibodies including CD45,CD38,CD138,CD117,CD56,and *** In AL,light chain restriction could be identified in 31 cases （60.9%）,in which the λ light chain restriction was found in 24 cases （77.4%）.In MM,κ light chain restriction was found in 13 cases （61.9%）,and λ light chain restriction in eight ***45 on abnormal plasma cells was negative to weakly positive in both AL and MM,but was positive to strongly positive in *** the bone marrow plasma cells of the 51 AL,78.4% were CD56＋,68.6% were CD117＋,and 88.2% were CD19-.While in the 21 MM cases,66.7% were CD56＋,38.1% were CD117＋,and 90.4% were CD19-.The plasmacytoid lymphocytes in the five WM patients were CD19＋ and CD56-,CD117-.Conclusion Detection of abnormal plasma cell clones in bone marrow by FCM is valuable for the diagnosis of AL.
