    Full text link
    Mobile communication standards were developed for enhancing transmission and network performance by using more radio resources and improving spectrum and energy efficiency. How to effectively address diverse user requirements and guarantee everyone's Quality of Experience (QoE) remains an open problem. The Sixth Generation (6G) mobile systems will solve this problem by utilizing heterogenous network resources and pervasive intelligence to support everyone-centric customized services anywhere and anytime. In this article, we first coin the concept of Service Requirement Zone (SRZ) on the user side to characterize and visualize the integrated service requirements and preferences of specific tasks of individual users. On the system side, we further introduce the concept of User Satisfaction Ratio (USR) to evaluate the system's overall service ability of satisfying a variety of tasks with different SRZs. Then, we propose a network Artificial Intelligence (AI) architecture with integrated network resources and pervasive AI capabilities for supporting customized services with guaranteed QoEs. Finally, extensive simulations show that the proposed network AI architecture can consistently offer a higher USR performance than the cloud AI and edge AI architectures with respect to different task scheduling algorithms, random service requirements, and dynamic network conditions

    Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

    EEG artifacts reduction by multivariate empirical mode decomposition and multiscale entropy for monitoring depth of anaesthesia during surgery

    Electroencephalography (EEG) has been widely utilized to measure the depth of anaesthesia (DOA) during operation. However, the EEG signals are usually contaminated by artifacts which have a consequence on the measured DOA accuracy. In this study, an effective and useful filtering algorithm based on multivariate empirical mode decomposition and multiscale entropy (MSE) is proposed to measure DOA. Mean entropy of MSE is used as an index to find artifacts-free intrinsic mode functions. The effect of different levels of artifacts on the performances of the proposed filtering is analysed using simulated data. Furthermore, 21 patients' EEG signals are collected and analysed using sample entropy to calculate the complexity for monitoring DOA. The correlation coefficients of entropy and bispectral index (BIS) results show 0.14 ± 0.30 and 0.63 ± 0.09 before and after filtering, respectively. Artificial neural network (ANN) model is used for range mapping in order to correlate the measurements with BIS. The ANN method results show strong correlation coefficient (0.75 ± 0.08). The results in this paper verify that entropy values and BIS have a strong correlation for the purpose of DOA monitoring and the proposed filtering method can effectively filter artifacts from EEG signals. The proposed method performs better than the commonly used wavelet denoising method. This study provides a fully adaptive and automated filter for EEG to measure DOA more accuracy and thus reduce risk related to maintenance of anaesthetic agents.This research was financially supported by the Center for Dynamical Biomarkers and Translational Medicine, National Central University, Taiwan, which is sponsored by Ministry of Science and Technology (Grant Number: NSC102-2911-I-008-001).

To research the effect of foliar spray with magnesium oxalate、ferrous、boric acid and molybdic acid on growth of Oncidum ‘Gower Ramsey’ . Foliar sprayed with 0.15 g/L of MgC2O4 on leaf fresh weight and dry weight had highest biomass accumulation.Then the pseudobulb length, width and thickness also had no significant differences while fresh weight and dry weight had the highest biomass in 0.15 g/L of MgC2O4. Compared with Fe-EDTA treatments, the fresh weight and dry weight of leaf and pseudobulb in 1 g/L of Fe-EDTA was higher than control. As ferrous concentration increased, the biomass accumulation of Oncidum ‘Gower Ramsey’ decreased. The fresh weight and dry weight of leaf and pseudobulb in 0.2 g/L of H3BO3 had highest biomass accumulation, but 0.1 g/L of H3BO3 treatment was good for leaf length、leaf width and pseudobulb growth and development. However, 0.15 g/L and 0.2 g/L of H3BO3 had the highest leaf thickness. As molybdic acid concentration increased, the fresh weight and dry weight of leaf and pseudobulb in 0.2 g/L of H2MoO4 was higher compared with control. The length, width and thickness of leaf and pseudobulb had the highest biomass in 0.05、0.1 g/L of H2MoO4, respectively. Foliar sprayed with magnesium oxalate, ferrous, boric acid, and molybdic acid, the leaf chlorophyll content improved through nine months cultivation, the upper leaf chlorophyll content had the highest value in 0.2 g/L of MgC2O4, 1g/L of Fe-EDTA, 0.15 g/L of H3BO3, and 0.2 g/L of H2MoO4, respectively. Both of total soluble sugar and starch were much higher at the pseudobulb stage, through nine months cultivation, then were decreased in the pseudobulb. Overall, foliar spray with 0.15 g/L MgC2O4 , 1g/L Fe-EDTA , 0.15 g/L H3BO3 , 0.2 g/L H2MoO4 on Oncidum ‘Gower Ramsey’ can increase leaf and pseudobulb biomass accumulation. The effect of foliar spray with magnesium oxalate、ferrous、boric acid and molybdic acid on vegetative and reproductive growth of Oncidum ‘Gower Ramsey’ are worth studying for further research.目錄(Content) 前言(Introduction)…………………………………………………… 1 前人研究(Literature review)………………………………………… 2 一、文心蘭植株特性……………………………………………………. 2 二、假球莖與生長之關係………………………………………………. 3 三、環境因子對蘭科植物生育之影響…………………………………. 6 四、營養元素對植物之影響……………………………………………. 7 材料方法(Marterials and Methods)………………………………… 14 一、植物材料…………………………………………………………… 14 二、試驗處理……………………………………………………………. 14 三、植株調查及分析方法………………………………………………. 15 結果(Results)………………………………………………………….. 18 一、葉面噴施草酸鎂對文心蘭葉片與假球莖生育之影響……………. 18 二、葉面噴施螯合鐵對文心蘭葉片與假球莖生育之影響……………. 20 三、葉面噴施硼酸對文心蘭葉片與假球莖生育之影響………………. 22 四、葉面噴施鉬酸對文心蘭葉片與假球莖生育之影響………………. 24 討論(Discussion)……………………………………………………… 91 一、葉面噴施草酸鎂對文心蘭葉片與假球莖生育之影響……………. 91 二、葉面噴施螯合鐵對文心蘭葉片與假球莖生育之影響……………. 92 三、葉面噴施硼酸對文心蘭葉片與假球莖生育之影響………………. 92 四、葉面噴施鉬酸對文心蘭葉片與假球莖生育之影響………………. 93 參考文獻(Reference)…………………………………………………. 94 附錄(Appendix)………………………………………………………. 10

    Multivariate Multiscale Entropy Applied to Center of Pressure Signals Analysis: An Effect of Vibration Stimulation of Shoes

    No full text
    Falls are unpredictable accidents and resulting injuries can be serious to the elderly. A preventative solution can be the use of vibration stimulus of white noise to improve the sense of balance. In this work, a pair of vibration shoes were developed and controlled by a touch-type switch which can generate mechanical vibration noise to stimulate the patient’s feet while wearing the shoes. In order to evaluate the balance stability and treatment effect of vibrating insoles in these shoes, multivariate multiscale entropy (MMSE) algorithm is applied to calculate the relative complexity index of reconstructed center of pressure (COP) signals in antero-posterior and medio-lateral directions by the multivariate empirical mode decomposition (MEMD). The results show that the balance stability of 61.5% elderly subjects is improved after wearing the developed shoes, which is more than 30.8% using multiscale entropy. In conclusion, MEMD-enhanced MMSE is able to distinguish the smaller differences between before and after the use of vibration shoes in both two directions, which is more powerful than the empirical mode decomposition (EMD)-enhanced MSE in each individual direction
