Methods Sixty children with CP were randomly divided into a scalp acupuncture combined with rehabilitation training group （group SA＋RT） and a rehabilitation training group （group RT） with 30 cases in each group. Conventional rehabilitation therapy and balance training were applied in group RT, and scalp acupuncture at close acupoints in the parietal region and sub-occipital region was added besides rehabilitation training in group SA＋RT. Balance functions were evaluated by using Berg rating scale, and abilities of daily living were estimated by using rating scale for activities of daily living （ADL）. Results After treatment, both Berg scores for balance and ADL scores were significantly improved in both groups （all P0.05）, and the improvement in group SA＋RT was more obvious than that in group RT （ both P0.05）. Conclusion Combination of scalp acupuncture at close acupoints with rehabilitation training is superior to simple rehabilitation training in improving balance functions and activities of daily living in children with cerebral palsy.展开更多

Current scoring system does not fulfill all our needs and requirements mostly because the same numeric score might reflect 28 different possible combinations of postural dysfunction in terms of anatomic region and laterality. Objective: We propose a new scoring method for the PDN-6 that would not change the clinical methods for the PDN-6 assessment. Specifically, new scoring method would clearly indicate specific patterns of postural dysfunction while still enabling statistical analyses. Methods: We developed a new scoring method for the PDN-6 without changing the instrument’s clinical procedures. We qualitatively assessed the validity of the new scoring system to detail specific patterns of postural dysfunction in terms of anatomic region and laterality. Results: New scoring method successfully deals with limitations of the previous scoring method. The new method enables clinicians to differentiate among 2 or more patients who might have very different patterns of postural dysfunction while still having the same numeric score using the previous scoring. The new scoring method provides quantitative data that are easily translated in terms of anatomic region and laterality for the postural dysfunctions that are present. Patient behavioral improvements are quantified, documented and interpreted with a change in score, and the exact nature of the improvements can be determined in terms of anatomic location and laterality. Rash analyses can also be used for statistical analyses. Conclusion: PDN-6 new scoring method provides quantitative data that provide more specific information about a patient’s postural deficits and any changes in their postural dysfunction over time without changing the clinical assessment methods.展开更多

This model uses the geographical information service ontology. In this paper, first we study the multilevel matching arithmetic of geographical information services. This arithmetic is used for filtering and matching the services in the service register center according to the similarity between services selected and services requested from the definition of the function similarity and credit standing similarity. The matching arithmetic, geographical information service ontology and semantic description constitute the discovering model. Finally, we test and analyze the model from the recall ratio, precision ratio, responsivity and load balance. The result indicates that the ontology-driven discovering model is excellent in recall ratio and precision ratio, and can maintain the dynamic load balance of service copy.展开更多

In the latter case, the monitor functions that steer mesh adaptation are oftendefined in an ad-hoc way. In this paper we generalize our previously used moni-tor function to a balanced sum of any number of monitor components. This avoidsthe trial-and-error parameter fine-tuning that is often used in monitor functions. Thekey reason for the new balancing method is that the ratio between the maximum andaverage value of a monitor component should ideally be equal for all components.Vorticity as a monitor component is a good motivating example for this. Entropy alsoturns out to be a very informative monitor component. We incorporate the monitorfunction in an adaptive moving mesh higher-order finite volume solver with HLLCfluxes, which is suitable for nonlinear hyperbolic systems of conservation laws. Whenapplied to compressible gas flow it produces very sharp results for shocks and otherdiscontinuities. Moreover, it captures small instabilities (Richtmyer-Meshkov, Kelvin-Helmholtz). Thus showing the rich nature of the example problems and the effective-ness of the new monitor balancing.展开更多

文摘Data from the Large Hadron Collider on the charge balance function in Pb+Pb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed and interpreted within the framework of the HYDJET++model.This model allows us to qualitatively reproduce the experimentally observed centrality dependence of the balance function widths at relatively low transverse momentum intervals due to the different charge creation mechanisms in soft and hard processes.However,a fully adequate description of the balance function in these intervals implies an essential modification of the model by including exact charge conservation via the canonical rather than the grand canonical ensemble.A procedure is proposed for introducing charge correlations into the thermal model without changing other model parameters.With increasing transverse momenta,the default model results describe the exper-imental data much better because the contribution of the soft component of the model is significantly reduced in these transverse momentum intervals.In practical terms,there is a transition to a single source of charge correlations,namely,charge correlations in jets in which exact charge conservation holds at each stage.
文摘Background:Patients undergoing hemodialysis suffer from deteriorating physical health,impaired physical function,and have a low quality of life,that explained by insufficient metabolic clearance.To overcome these obstacles,cost-effective strategies must be developed,including exercise as a complement to hemodialysis therapy.Objective:To determine the effectiveness of exercise therapy on functional balance,physical performance,and quality of life among patients undergoing hemodialysis:a randomized controlled trial.Methods:This randomized controlled trial study was carried out on 68 patients with chronic kidney disease undergoing hemodialysis for at least six months and had a medically stable condition who were randomly divided into training(n=32)exercise therapy and(n=31)control,groups.The training group participated in 8-week(3 sessions per week)resistance exercise therapy in three sets of 10 repetitions of knee extension,hip flexion,and hip abduction with the use of an elastic band under the supervision of a training physiotherapist and researcher during the first hour of the three routine hemodialysis treatment session per week.But the control group did not experience any intervention.To analyze the data,two-way analysis of variance and Bonferroni statistical tests were used at the significant level of(P=0.05).Results:6 Minute-Walk Test(6MWT)(0.013),and in the Physical Activity Scale for the Elderly(PASE)(0.014),and Short Survey Form 36(SF-36)questionnaires and health-related quality of life(HRQOL)(0.001)had significant improvements in the training group in comparison to the control group from pre to post-test,also physical performance(0.001)was improving as compared with control group(0.89)at(P=0.05).Conclusion:Resistance exercise therapy interventions for eight weeks effectively improve the physical function and performance,activity levels,and health-related quality of life of patients with chronic kidney disease and undergoing regular hemodialysis compared with a control group.

文摘It is difficult to determine the effective reservoir rock compressibility,aquifer volume and water influx of high pressure and ultra-high pressure gas reservoirs,so when the traditional apparent reservoir pressure and cumulative gas production curve extrapolation method and its modified version are used to calculate the initial gas in-place of such gas reservoirs,the calculation accuracy is lower.The material balance equation in the form of power function for such gas reservoirs was established based on Gonzalez method to improve the accuracy and reliability of reserve evaluation.Then,based on 20 high pressure and ultra-high pressure reservoirs that had been developed abroad,the empirical value of the power exponent was defined,and the influences of the depletion degree of apparent reservoir pressure and the degree of reserve recovery on the reliability of reserve calculation were analyzed.Besides,the critical value of the key parameter affecting the reliability of reserve evaluation(depletion degree of apparent reservoir pressure)was determined and compared with the critical value of the two-linear trends.Finally,an example calculation was carried out.And the following research results were obtained.First,the empirical value of the power exponent calculated using the material balance method in the form of power function is 1.02847,with an upper limit of 1.11567.Second,the depletion degree of apparent reservoir pressure corresponding to the inflection point of the classical two-linear trends ranges from 0.14 to 0.38 with an average of 0.23,while that corresponding to the extrapolation point of the second straight line is between 0.23 and 0.50 with an average of 0.33,and the corresponding degree of reserve recovery is in the range of 33%-65%with an average of 45%.Third,the reserves of such high pressure gas reservoirs calculated with this new method has an error rate less than 10%if the depletion degree of apparent reservoir pressure is greater than 0.33.In conclusion,for such high pressure gas reservoirs and the stress-sensitive fractured gas reservoirs,the material balance method in the form of power function proposed in this paper can avoid the uncertainty parameters(e.g.effective reservoir rock compressibility,aquifer volume and water influx)and it is advantageous with simple calculation process,better practicability and small error.

文摘This study combined fault identification with a deep learning algorithm and applied a convolutional neural network(CNN)design based on an improved balanced crossentropy(BCE)loss function to address the low accuracy in the intelligent identification of seismic faults and the slow training speed of convolutional neural networks caused by unbalanced training sample sets.The network structure and optimal hyperparameters were determined by extracting feature maps layer by layer and by analyzing the results of seismic feature extraction.The BCE loss function was used to add the parameter which is the ratio of nonfaults to the total sample sets,thereby changing the loss function to find the reference of the minimum weight parameter and adjusting the ratio of fault to nonfault data.The method overcame the unbalanced number of sample sets and improved the iteration speed.After a brief training,the accuracy could reach more than 95%,and gradient descent was evident.The proposed method was applied to fault identification in an oilfield area.The trained model can predict faults clearly,and the prediction results are basically consistent with an actual case,verifying the effectiveness and adaptability of the method.
文摘Background: Posturodynamic 6 (PDN-6) is a clinical assessment of posture that merges the Clinical Posturodynamic Test and the Pelvic Maintain Test. Current scoring system does not fulfill all our needs and requirements mostly because the same numeric score might reflect 28 different possible combinations of postural dysfunction in terms of anatomic region and laterality. Objective: We propose a new scoring method for the PDN-6 that would not change the clinical methods for the PDN-6 assessment. Specifically, new scoring method would clearly indicate specific patterns of postural dysfunction while still enabling statistical analyses. Methods: We developed a new scoring method for the PDN-6 without changing the instrument’s clinical procedures. We qualitatively assessed the validity of the new scoring system to detail specific patterns of postural dysfunction in terms of anatomic region and laterality. Results: New scoring method successfully deals with limitations of the previous scoring method. The new method enables clinicians to differentiate among 2 or more patients who might have very different patterns of postural dysfunction while still having the same numeric score using the previous scoring. The new scoring method provides quantitative data that are easily translated in terms of anatomic region and laterality for the postural dysfunctions that are present. Patient behavioral improvements are quantified, documented and interpreted with a change in score, and the exact nature of the improvements can be determined in terms of anatomic location and laterality. Rash analyses can also be used for statistical analyses. Conclusion: PDN-6 new scoring method provides quantitative data that provide more specific information about a patient’s postural deficits and any changes in their postural dysfunction over time without changing the clinical assessment methods.

文摘This paper proposes an ontology-driven discovering model for the geographical information services to improve their recall ratio and precision ratio. This model uses the geographical information service ontology. In this paper, first we study the multilevel matching arithmetic of geographical information services. This arithmetic is used for filtering and matching the services in the service register center according to the similarity between services selected and services requested from the definition of the function similarity and credit standing similarity. The matching arithmetic, geographical information service ontology and semantic description constitute the discovering model. Finally, we test and analyze the model from the recall ratio, precision ratio, responsivity and load balance. The result indicates that the ontology-driven discovering model is excellent in recall ratio and precision ratio, and can maintain the dynamic load balance of service copy.

文摘Adaptive moving mesh research usually focuses either on analytical deriva-tions for prescribed solutions or on pragmatic solvers with challenging physical appli-cations. In the latter case, the monitor functions that steer mesh adaptation are oftendefined in an ad-hoc way. In this paper we generalize our previously used moni-tor function to a balanced sum of any number of monitor components. This avoidsthe trial-and-error parameter fine-tuning that is often used in monitor functions. Thekey reason for the new balancing method is that the ratio between the maximum andaverage value of a monitor component should ideally be equal for all components.Vorticity as a monitor component is a good motivating example for this. Entropy alsoturns out to be a very informative monitor component. We incorporate the monitorfunction in an adaptive moving mesh higher-order finite volume solver with HLLCfluxes, which is suitable for nonlinear hyperbolic systems of conservation laws. Whenapplied to compressible gas flow it produces very sharp results for shocks and otherdiscontinuities. Moreover, it captures small instabilities (Richtmyer-Meshkov, Kelvin-Helmholtz). Thus showing the rich nature of the example problems and the effective-ness of the new monitor balancing.
