After synchronizing the actual data, Fourier and wavelet transformations were adopted in order to obtain the sideband or detail value characteristics under healthy and various faulty operating conditions. The most reliable phase current among the three phase currents was selected using an approach that employs the fuzzy entropy measure. Data were trained with a neural network system, and the fault detection algorithm was verified using the unknown data. Results of the proposed approach based on Fourier and wavelet transformations indicate that the faults can be properly classified into six categories. The training error is 5.3×10-7, and the average test error is 0.103.展开更多

The purpose of this study was to evaluate the feasibility of different methods such as artificial neural networks(ANN) and two geostatistical methods(geographically weighted regression(GWR) and cokriging(CK)) to estimate N, P and K contents. For this purpose, soil samples were taken from topsoil(0–30 cm) at 106 points and analyzed for their chemical and physical parameters. These data were divided into calibration(n = 84) and validation(n = 22). Chemical and physical variables including clay, p H and organic carbon(OC) were used as auxiliary soil variables to estimate the N, P and K contents. Results showed that the ANN model(with coefficient of determination R^2 = 0.922 and root mean square error RMSE = 0.0079%) was more accurate compared to the CK model(with R^2 = 0.612 and RMSE = 0.0094%), and the GWR model(with R^2 = 0.872 and RMSE = 0.0089%) to estimate the N variable. The ANN model estimated the P with the RMSE of 3.630 ppm, which was respectively 28.93% and 20.00% less than the RMSE of 4.680 ppm and 4.357 ppm from the CK and GWR models. The estimated K by CK, GWR and ANN models have the RMSE of 76.794 ppm, 75.790 ppm and 52.484 ppm. Results indicated that the performance of the CK model for estimation of macro nutrients(N, P and K) was slightly lower than the GWR model. Also, the accuracy of the ANN model was higher than CK and GWR models, which proved to be more effective and reliable methods for estimating macro nutrients.展开更多

This is the part of the brain already present in the embryo and consists of the brainstem, hypothalamus, thalamus, and midbrain. It is also the part of the brain that operates during dreaming and deep sleep and causes the transition from sleeping to waking states, and the Upanishads state unequivocally that the self is responsible for these mental states. With the self located in the embryo brain region, an entirely new interpretation of Aristotle's De Anima is presented which parallels the Upanishads in every respect; the inner self and Aristotle's "soul" have identical functions and attributes. An Aristotelian First Principle is presented: Biology is the source of Consciousness; DNA is the source of Biology; Ergo DNA is the source of Consciousness.展开更多

Methods: Male SD rats anesthetized with chloral hydrate were randomly divided into 3 groups which were treated with manual acupuncture (MA), injection of lidocaine followed by MA and injection of normal saline (NS) followed by MA, respectively. The right carotid artery was canulated for persistent measurement of the blood pressure and meanwhile nerve discharges from the nerve-tract were recorded for analysis with amplitude spike counts for every 5 s. Results: The results showed that there were significant nerve discharges recorded from the nerve-tract when applying MA at Zusanli (ST 36) and simultaneous decrease in the MAP, while there was no response when inserting a needle into the Zusanli (ST 36) without manipulation (P〈0.05). Furthermore, the reduction of MAP during MA could be completely abolished after blockade of peripheral nerve discharges with an injection of lidocaine into the tissue around Zusanli (ST 36) but not with that of normal saline (NS). Conclusion: These results indicate that MA at Zusanli (ST 36) can elicit the peripheral nerve discharges from the nerve innervating the acupoint; such kind of nerve discharges may contain acupuncture signal regulating blood pressure via somato-cardiovascular reflex.展开更多

Methods: it is reviewed for the authors' studies of characteristics of afferent nerve response, somato-sympathetic reflex (one of the somato-autonomic reflexes) and glutamate derived central modulation, target tissue and organ responses to somatic stimulation of acupuncture or electrical shock in rats and mice. Results and Conclusion: An electrical discharge from the nerve afferent serving Zusanli (ST 36) was recorded by applying manual acupuncture or electroacupuncture to Zusanli (ST 36). Such process could be replaced by applying electric shock directly to the afferent nerve assumingly. Somatic electrical stimulation of the afferent nerve e.g. tibia nerve can reflexively elicit an electrical discharge from autonomic efferent nerve e.g. sympathetic nerve that is defined as somato-sympathetic reflex. The reflex can be modulated by an excitatory neurotransmitter of glutamate in the central pathways. On the other hand, somatic stimulation of Zusanli (ST 36), etc. by electroacupuncture showed that there were inhibitory modulation of somatic sensory input from target tissue of the inflammatory pain in the hind paw of the mouse and visceral sensory input from target organ of the colorectum hyperagesia in the irritable bowel syndrome (IBS) rat. Spinal GABA and NMDA receptors were proved to be involved in the former and latter processes, respectively.展开更多

Methods: 63 cases of patients were randomly divided into Group A (32 cases) and Group B (31 cases). In both groups, mild moxibustion was applied bilaterally to Zusanli (ST 36). The treatment was given once a day for group A and once every other day for group B. The therapeutic effects of the two groups were summarized after twelve weeks. Results: The two groups are remarkably significant in reducing total cholesterol (TC) (P〈0.001), and also remarkably significant in reducing triglyceride (TG), low density lipoprotein cholesterin (LDL-C) and in elevating high density lipoprotein cholesterin (HDL-C) (P〈0.05); and not evident in improving apolipotroten (ApoAI), apoliporotein B (ApoB), and lipoprotein a [Lp (a)]; however ApoAI showed an obvious tendency to rise, and ApoB and Lp (a) showed an tendency to decrease. There is no statistic significance in comparison between the groups. Conclusion: Mild moxibustion for primary hyperlipidemia can be applied by a plan of one treatment every other day.展开更多

Methods: A total of 35 football players were randomly allocated into a blank group, a control group and an observation group. The athletes in the blank group received no treatment, those in the control group take Xi Yang Shen (Radix Panacis Quinquefolii) orally and those in the observation group were treated by point sticking therapy. The athletes' RPE, hemoglobin (Hb), red blood cell count (RBC), blood urea nitrogen (BUN) and blood glucose (BG) were recorded every day for analysis. Results: The RPE value in the blank group tends to increase, while that in the treatment and the blank groups tend to increase first but decrease afterwards, and the corresponding RPE value in the observation group was smaller than that in the control group. After treatment, athletes in the blank group showed a decrease in Hb, RBC and BG, but an increase in BUN in the blank group; while athletes in the observation and the control groups showed increases in Hb, RBC and BG, but a decrease in BUN. Conclusion: Point sticking can alleviate clinical symptoms induced by exercise-induced fatigue.展开更多

文摘Soil macronutrients(i.e. nitrogen(N), phosphorus(P), and potassium(K)) are important soils components and knowing the spatial distribution of these parameters are necessary at precision agriculture. The purpose of this study was to evaluate the feasibility of different methods such as artificial neural networks(ANN) and two geostatistical methods(geographically weighted regression(GWR) and cokriging(CK)) to estimate N, P and K contents. For this purpose, soil samples were taken from topsoil(0–30 cm) at 106 points and analyzed for their chemical and physical parameters. These data were divided into calibration(n = 84) and validation(n = 22). Chemical and physical variables including clay, p H and organic carbon(OC) were used as auxiliary soil variables to estimate the N, P and K contents. Results showed that the ANN model(with coefficient of determination R^2 = 0.922 and root mean square error RMSE = 0.0079%) was more accurate compared to the CK model(with R^2 = 0.612 and RMSE = 0.0094%), and the GWR model(with R^2 = 0.872 and RMSE = 0.0089%) to estimate the N variable. The ANN model estimated the P with the RMSE of 3.630 ppm, which was respectively 28.93% and 20.00% less than the RMSE of 4.680 ppm and 4.357 ppm from the CK and GWR models. The estimated K by CK, GWR and ANN models have the RMSE of 76.794 ppm, 75.790 ppm and 52.484 ppm. Results indicated that the performance of the CK model for estimation of macro nutrients(N, P and K) was slightly lower than the GWR model. Also, the accuracy of the ANN model was higher than CK and GWR models, which proved to be more effective and reliable methods for estimating macro nutrients.

文摘Objective: To reveal the neuropathways of acupuncture effect on regulation of autonomic functions, treatment of diseases and the relationship between treating acupoint and certain target tissue or organ. Methods: it is reviewed for the authors' studies of characteristics of afferent nerve response, somato-sympathetic reflex (one of the somato-autonomic reflexes) and glutamate derived central modulation, target tissue and organ responses to somatic stimulation of acupuncture or electrical shock in rats and mice. Results and Conclusion: An electrical discharge from the nerve afferent serving Zusanli (ST 36) was recorded by applying manual acupuncture or electroacupuncture to Zusanli (ST 36). Such process could be replaced by applying electric shock directly to the afferent nerve assumingly. Somatic electrical stimulation of the afferent nerve e.g. tibia nerve can reflexively elicit an electrical discharge from autonomic efferent nerve e.g. sympathetic nerve that is defined as somato-sympathetic reflex. The reflex can be modulated by an excitatory neurotransmitter of glutamate in the central pathways. On the other hand, somatic stimulation of Zusanli (ST 36), etc. by electroacupuncture showed that there were inhibitory modulation of somatic sensory input from target tissue of the inflammatory pain in the hind paw of the mouse and visceral sensory input from target organ of the colorectum hyperagesia in the irritable bowel syndrome (IBS) rat. Spinal GABA and NMDA receptors were proved to be involved in the former and latter processes, respectively.
文摘Objective To explore the effect of moxibustion at Shenque(CV 8)on myocardial structure and function in exercise-induced fatigue rats.Methods A 12-week treadmill running training was performed to create an exercise-induced fatigue rat model.Sixty eligible male specific-pathogen-free grade Sprague-Dawley rats were randomly divided into a blank group,a control group,a model group,a non-meridian non-acupoint group,a Zusanli(ST 36)group and a Shenque(CV 8)group,with 10 rats in each group.Rats in the blank group did not receive treadmill running training or moxibustion.Rats in the control group did not receive treadmill running training but received mild moxibustion at Shenque(CV 8).Rats in the model group received treadmill running training but no moxibustion.Rats in the non-meridian non-acupoint group,the Zusanli(ST 36)group and the Shenque(CV 8)group received moxibustion at the non-meridian non-acupoint points,Zusanli(ST 36)or Shenque(CV 8)immediately after each treadmill running training,15 min each time,once a day for 5 consecutive days a week at a 2-day interval,60 times of moxibustion in total.Left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVESd),left ventricular diastolic volume(LVDv),left ventricular systolic volume(LVSv),ejection fraction(EF),stroke volume(SV),early diastolic peak flow velocity of mitral valve(E)and late diastolic peak flow velocity of mitral valve(A)of each group before and after the last treadmill running training were measured.Blood was collected 6 h after the last treadmill running training,and serum C-reactive protein(CRP),myoglobin(Mb),creatine kinase-myocardial band(CK-MB),cardiac troponin I(cTnI)and cardiac troponin T(cTnT)levels were detected.Finally,the heart was separated,the heart mass(HM)was measured,the cTnT level of the myocardial tissue was detected,the ultrastructural changes of the left ventricular myocardium were observed by transmission electron microscope,the left ventricular fraction shortening(LVFS),E/A and heart mass index(HMI)were calculated.Results Compared with the same group before treatment,the rat cardiac LVEDd,LVESd,LVDv,LVSv,SV,E and A were significantly increased(all P<0.01),and the rat LVFS,E/A and EF were significantly decreased(all P<0.01)in the model group and the non-meridian non-acupoint group after treatment;the rat cardiac SV,LVDv,LVSv,E and A were all increased(all P<0.01),while E/A and EF were decreased(all P<0.01)in the Zusanli(ST 36)group after treatment;the rat cardiac LVDv,E and A were significantly increased(P<0.01 or P<0.05),and E/A was significantly decreased(P<0.01)in the Shenque(CV 8)group after treatment.After treatment,compared with the blank group,the rat cardiac LVEDd,LVESd,SV,LVDv,LVSv,E,A,the serum CRP,Mb,CK-MB,cTnI,cTnT and HMI,and the myocardial cTnT were increased(all P<0.01),and the LVFS,E/A and EF were all reduced(all P<0.01)in the model group;compared with the model group and the non-meridian non-acupoint group,rats in the Zusanli(ST 36)group and the Shenque(CV 8)group showed decreased LVEDd,LVESd,SV,LVDv,LVSv,E,A,serum CRP,Mb,CK-MB,cTnI,cTnT and HMI,and myocardial cTnT(P<0.01 or P<0.05),along with increased LVFS,E/A and EF(all P<0.01);compared with the Zusanli(ST 36)group,Mb and A of the Shenque(CV 8)group were decreased(both P<0.01),while both E/A and EF were increased(P<0.01,P<0.05).Transmission electron microscopy examination showed that myofibrils in the blank group and the control group were neatly arranged with clear light and dark bands;the model group and the non-meridian non-acupoint group showed different degrees of myofibril disintegration and breakage,increased and aggregated mitochondria of different sizes,and increased electron density.The myofibrils in the Shenque(CV 8)group and Zusanli(ST 36)group were arranged neatly with clear light and dark bands,and compensatory hyperplasia of mitochondria.Conclusion Moxibustion at Shenque(CV 8)and Zusanli(ST 36)both can effectively improve the occurrence of myocardial remodeling in exercise-induced fatigue rats,and the effect of moxibustion at Shenque(CV 8)is better in improving cardiac function.

文摘Several methods,including stepwise regression,ordinary kriging,cokriging,kriging with external drift,kriging with varying local means,regression-kriging,ordinary artificial neural networks,and kriging combined with artificial neural networks,were compared to predict spatial variation of saturated hydraulic conductivity from environmental covariates.All methods except ordinary kriging allow for inclusion of secondary variables.The secondary spatial information used was terrain attributes including elevation,slope gradient,slope aspect,profile curvature and contour curvature.A multiple jackknifing procedure was used as a validation method.Root mean square error (RMSE) and mean absolute error (MAE) were used as the validation indices,with the mean RMSE and mean MAE used to judge the prediction quality.Prediction performance by ordinary kriging was poor,indicating that prediction of saturated hydraulic conductivity can be improved by incorporating ancillary data such as terrain variables.Kriging combined with artificial neural networks performed best.These prediction models made better use of ancillary information in predicting saturated hydraulic conductivity compared with the competing models.The combination of geostatistical predictors with neural computing techniques offers more capability for incorporating ancillary information in predictive soil mapping.There is great potential for further research and development of hybrid methods for digital soil mapping.
文摘Objective: To observe the influence of mild moxibustion by different intervals on the therapeutic effect of the patients with primary hyperlipidemia. Methods: 63 cases of patients were randomly divided into Group A (32 cases) and Group B (31 cases). In both groups, mild moxibustion was applied bilaterally to Zusanli (ST 36). The treatment was given once a day for group A and once every other day for group B. The therapeutic effects of the two groups were summarized after twelve weeks. Results: The two groups are remarkably significant in reducing total cholesterol (TC) (P〈0.001), and also remarkably significant in reducing triglyceride (TG), low density lipoprotein cholesterin (LDL-C) and in elevating high density lipoprotein cholesterin (HDL-C) (P〈0.05); and not evident in improving apolipotroten (ApoAI), apoliporotein B (ApoB), and lipoprotein a [Lp (a)]; however ApoAI showed an obvious tendency to rise, and ApoB and Lp (a) showed an tendency to decrease. There is no statistic significance in comparison between the groups. Conclusion: Mild moxibustion for primary hyperlipidemia can be applied by a plan of one treatment every other day.
文摘Objective:To observe the effects of moxibustion at Shenshu(BL 23),Zusanli(ST 36)and Shenque(CV 8)on the energy metabolism and endocrine metabolism indicators of rats undergoing one-time exhaustive swimming,and to explore the differences between moxibustion at different points in the effects on anti-exercise fatigue.Methods:Forty-eight male SPF rats were randomly divided into a blank group,a model group,a non-meridian and non-acupoint group,a Shenshu(BL 23)group,a Zusanli(ST 36)group,and a Shenque(CV 8)group using random number table method,with eight rats in each group.Except for the blank group,rats in the other groups were subjected to replicating the one-time exhaustive model using the weight-bearing swimming experiment.Except for the model group,the other model rats received mild moxibustion immediately after swimming.Rats in the non-meridian and non-acupoint group received mild moxibustion at bilateral subcostal non-meridian and non-acupoint points,those in the Shenshu(BL 23)group received mild moxibustion at bilateral Shenshu(BL 23),those in the Zusanli(ST 36)group received mild moxibustion at bilateral Zusanli(ST 36),and those in the Shenque(CV 8)group received mild moxibustion at Shenque(CV 8)for 15 min.Four hours after the exhaustive swimming,femoral artery blood was collected to detect blood lactate(BLA),lactate dehydrogenase(LDH),creatine kinase(CK),creatinine(CRE),blood urea nitrogen(BUN),cortisol(C)and testosterone(T)levels,and calculate the T/C ratio.Results:Compared with the blank group,rat's serum levels of BLA,LDH,CK,BUN and C in the model group and the non-meridian and non-acupoint group were increased,and serum levels of CRE and T,and T/C ratios were decreased(P<0.01 or P<0.05);compared with the model group and the non-meridian and non-acupoint group,the serum levels of BLA,LDH,CK,BUN and C in the Shenshu(BL 23)group,Zusanli(ST 36)group and Shenque(CV 8)group were decreased,and the serum CRE and T levels,and the T/C ratios were increased(all P<0.01);compared with the Shenshu(BL 23)group,the serum CK level was decreased in the Shenque(CV 8)group(P<0.01),the serum levels of T and C were decreased in the Zusanli(ST 36)group and Shenque(CV 8)group(P<0.01 or P<0.05),and the T/C ratio was increased in the Shenque(CV 8)group(P<0.01);compared with the Zusanli(ST 36)group,the serum CK and BUN levels were decreased(P<0.01,P<0.05),and the T/C ratio was increased in the Shenque(CV 8)group(P<0.05).Conclusion:Moxibustion at Shenshu(BL 23),Zusanli(ST 36)and Shenque(CV 8)shows different anti-fatigue effects by regulating the energy metabolism and endocrine metabolism in rats undergoing one-time exhaustive swimming.Moxibustion at Shenshu(BL 23)is better in promoting energy synthesis.Moxibustion at Shenque(CV 8)is more effective in regulating synthesis and decomposition of the skeletal muscle proteins.

文摘Objective: To observe the effect of point sticking therapy on biochemical markers and Rating of Perceived Exertion (RPE) in athletes with exercise-induced fatigue. Methods: A total of 35 football players were randomly allocated into a blank group, a control group and an observation group. The athletes in the blank group received no treatment, those in the control group take Xi Yang Shen (Radix Panacis Quinquefolii) orally and those in the observation group were treated by point sticking therapy. The athletes' RPE, hemoglobin (Hb), red blood cell count (RBC), blood urea nitrogen (BUN) and blood glucose (BG) were recorded every day for analysis. Results: The RPE value in the blank group tends to increase, while that in the treatment and the blank groups tend to increase first but decrease afterwards, and the corresponding RPE value in the observation group was smaller than that in the control group. After treatment, athletes in the blank group showed a decrease in Hb, RBC and BG, but an increase in BUN in the blank group; while athletes in the observation and the control groups showed increases in Hb, RBC and BG, but a decrease in BUN. Conclusion: Point sticking can alleviate clinical symptoms induced by exercise-induced fatigue.
