Being different from testing for popular GUI software, the “instruction-category” approach is proposed for testing embedded system. This approach is constructed by three steps including refining items, drawing instruction-brief and instruction-category, and constructing test suite. Consequently, this approach is adopted to test oven embedded system, and detail process is deeply discussed. As a result, the factual result indicates that the “instruction-category” approach can be effectively applied in embedded system testing as a black-box method for conformity testing. 展开更多

Addressing classification and prediction challenges, tree ensemble models have gained significant importance. Boosting ensemble techniques are commonly employed for forecasting Type-II diabetes mellitus. Light Gradient Boosting Machine (LightGBM) is a widely used algorithm known for its leaf growth strategy, loss reduction, and enhanced training precision. However, LightGBM is prone to overfitting. In contrast, CatBoost utilizes balanced base predictors known as decision tables, which mitigate overfitting risks and significantly improve testing time efficiency. CatBoost’s algorithm structure counteracts gradient boosting biases and incorporates an overfitting detector to stop training early. This study focuses on developing a hybrid model that combines LightGBM and CatBoost to minimize overfitting and improve accuracy by reducing variance. For the purpose of finding the best hyperparameters to use with the underlying learners, the Bayesian hyperparameter optimization method is used. By fine-tuning the regularization parameter values, the hybrid model effectively reduces variance (overfitting). Comparative evaluation against LightGBM, CatBoost, XGBoost, Decision Tree, Random Forest, AdaBoost, and GBM algorithms demonstrates that the hybrid model has the best F1-score (99.37%), recall (99.25%), and accuracy (99.37%). Consequently, the proposed framework holds promise for early diabetes prediction in the healthcare industry and exhibits potential applicability to other datasets sharing similarities with diabetes. 展开更多

This study focuses on the effect of the total serum protein(TSP)concentrations at 3 days after birth on the health and growth parameters of preweaned female Holstein Friesian calves.A total of 165 female calves were enrolled and evaluated for morbidity which included diarrhea(D),respiratory disease(Rd)and omphalitis(O).Also,calves with more than one disorder in the same time were recorded as multi-morbid.Body weight(BW)was determined at birth,30 and 60 days of age.Blood samples were taken at 3 days after birth and TSP was determined using a digital Brix refractometer.For statistical analysis all female calves based on TSP concentration were grouped into 3 categories:1-TSP≥6.2 g/dL,2-TSP 5.8-6.1 g/dL,and 3-TSP<5.8 g/dL.Overall,the average of TSP concentration was 6.38 g/dL.The prevalence of diarrhea,respiratory disease(Rd)and omphalitis(O)was 16.96%,7.88%and 4.85%respectively,in calves with one disorder and 6.06%in calves with D+Rd,3.64%in calves with Rd+O,3.03%in calves with O+D,and 3.64%in calves with D+Rd+O.As the TSP concentration in calves decreased from≥6.2 g/dL to<5.8 g/dL the calf hood disorders increased in female calves with one disorder and with more than one disorder.The female calves with fair to poor immunity(category 3-TSP<5.8 g/dL)were significantly more likely(OR 6.28,95%CI 2.91-13.5,p value<0.001)to be affected by diseases compared with female calves with excellent immunity(category 1-TSP≥6.2 g/dL).Also BW and average daily gain(ADG)at 30 and 62 days of life decreased as TSP concentrations decreased.The female calves with TSP≥6.2 g/dL at 3 days of life had the greatest BW at 30 and 62 days of age(51.8 kg and 77.1 kg respectively)compared with female calves with TSP<5.8 g/dL at 3 days of life(46.6 and 70.6 kg respectively).Moreover,starter feed intake during the first 30 days of life,31 to 62 days of life and 1 to 62 days of life was greater in female calves with excellent immunity(TSP≥6.2 g/dL)than female calves with good immunity(TSP 5.8-6.1 g/dL)or with fair to poor immunity(<5.8 g/dL TSP).Measuring the TSP at 3 days of calf’s This study focuses on the effect of the total serum protein(TSP)concentrations at 3 days after birth on the health and growth parameters of preweaned female Holstein Friesian calves.A total of 165 female calves were enrolled and evaluated for morbidity which included diarrhea(D),respiratory disease(Rd)and omphalitis(O).Also,calves with more than one disorder in the same time were recorded as multi-morbid.Body weight(BW)was determined at birth,30 and 60 days of age.Blood samples were taken at 3 days after birth and TSP was determined using a digital Brix refractometer.For statistical analysis all female calves based on TSP concentration were grouped into 3 categories:1-TSP≥6.2 g/dL,2-TSP 5.8-6.1 g/dL,and 3-TSP<5.8 g/dL.Overall,the average of TSP concentration was 6.38 g/dL.The prevalence of diarrhea,respiratory disease(Rd)and omphalitis(O)was 16.96%,7.88%and 4.85%respectively,in calves with one disorder and 6.06%in calves with D+Rd,3.64%in calves with Rd+O,3.03%in calves with O+D,and 3.64%in calves with D+Rd+O.As the TSP concentration in calves decreased from≥6.2 g/dL to<5.8 g/dL the calf hood disorders increased in female calves with one disorder and with more than one disorder.The female calves with fair to poor immunity(category 3-TSP<5.8 g/dL)were significantly more likely(OR 6.28,95%CI 2.91-13.5,p value<0.001)to be affected by diseases compared with female calves with excellent immunity(category 1-TSP≥6.2 g/dL).Also BW and average daily gain(ADG)at 30 and 62 days of life decreased as TSP concentrations decreased.The female calves with TSP≥6.2 g/dL at 3 days of life had the greatest BW at 30 and 62 days of age(51.8 kg and 77.1 kg respectively)compared with female calves with TSP<5.8 g/dL at 3 days of life(46.6 and 70.6 kg respectively).Moreover,starter feed intake during the first 30 days of life,31 to 62 days of life and 1 to 62 days of life was greater in female calves with excellent immunity(TSP≥6.2 g/dL)than female calves with good immunity(TSP 5.8-6.1 g/dL)or with fair to poor immunity(<5.8 g/dL TSP).Measuring the TSP at 3 days of calf’s life,offers information directly correlated to an individual calf’s immunity status,their likeliness of morbidity,mortality and body development and overall the effectiveness of the colostrum management program in the dairy farm.life,offers information directly correlated to an individual calf’s immunity status,their likeliness of morbidity,mortality and body development and overall the effectiveness of the colostrum management program in the dairy farm. 展开更多

The question of how the category of entwined modules can be made into a braided monoidal category is studied. First, the sufficient and necessary conditions making the category into a monoidal category are obtained by using the fact that if (A, C, ψ) is an entwining structure, then A × C can be made into an entwined module. The conditions are that the algebra and coalgebra in question are both bialgebras with some extra compatibility relations. Then given a monodial category of entwined modules, the braiding is constructed by means of a twisted convolution invertible map Q, and the conditions making the category form into a braided monoidal category are obtained similarly. Finally, the construction is applied to the category of Doi-Hopf modules and (α, β )-Yetter-Drinfeld modules as examples. 展开更多

Let H be a commutative, noetherian, semisimple and cosemisimple Hopf algebra with a bijective antipode over a field k. Then the semisimplicity of YD(H) is considered, where YD (H) means the disjoint union of the category of generalized Yetter-Drinfeld modules nYD^H( α, β) for any α, β E Aut Hopf(H). First, the fact that YD(H) is closed under Mor is proved. Secondly, based on the properties of finitely generated projective modules and semisimplicity of H, YD(H) satisfies the exact condition. Thus each object in YD(H) can be decomposed into simple ones since H is noetherian and cosemisimple. Finally, it is proved that YD (H) is a sernisimple category. 展开更多

People gradually learn that in grammar category, nominalization has a very close relation to the category of discourse. This article discusses nominalization from the viewpoints of three linguistic schools, then goes into the systemic functional linguistics in particular, and points out that nominalization is due to the need of communication, and has a very close relation to the category of discourse. Through the analysis of chosen language materials, this article wants to prove that the frequency of nominalization is in direct proportion to the degree of the formality of the category of discourse. That is to say, the higher the frequency is, the higher the degree is. It 's the same the other way round. 展开更多

Neologisms are the result of people's conceptualization of new things based on their life experiences. Cognitive linguistics views that categorization of organisms and concrete objects are based on the prototype category. This paper takes 167 English Neologisms from Wordspy in2015 as the data for analysis and finds that these English Neologisms are characterized by family resemblances, degree of membership in category and boundary fuzziness from the view of prototype category theory. This study also has some implications for the research of English language teaching and learning. 展开更多

Background: One of the goals for training in judo is to mimic real situations. In subsaharian countries;there is a lack of knowledge considering relation between category of weight and threshold maximum oxidation of lipids. Objectives: The main objectives of this study were to analyze the effect of category of weight on lipoxmax and to identify the zones of target intensities corresponding to lipoxmax. Materials and Methods:Twenty four male well-training judoists, divided in two groups according to weight, were evaluated during calorimetry effort’ test. For this situation, cardiorespiratory parameters (HR, VO2, VO2max), blood parameter (lactatemia), anthropometric variables and zones of target corresponding to lipox were evaluated. For statistical analysis, Shapiro-Wilks test was used to compare all the data and differences were confirmed by one-way variance. Results: No significant differences were observed among two groups for target intensities to lipox. The judoists of group 1 were aged to 24.1 ± 5.9 years with 1.78 ± 0.07 m versus 20.4 ± 1.6 years with 1.86 ± 0.04 m. Primary results indicated higher intensities for lipoxmax. Also, values of power (% LDC) and VO2 and were significantly higher in the judoists for group 2, with respectively: 45.3 ± 10.2 and 46.4 ± 8.6 ml/min versus 38.2 ± 7.2 and 31.3 ± 7.6 ml/min. Conclusion: High weight in judoists induces high intensities of lipoxmax and change oxidation of lipids markers following training. 展开更多

Introduction: In this paper we investigate the possible connection between socioeconomic status as demarcated by employment and in-surance status and consumption of healthcare resources in spine surgery patients. Methods: The clinical records of 1599 spine surgery pa-tients counted from 2008-2009 were reviewed. The largest groups of patients belonged to MS-DRG 460 (N = 585) and to MS-DRG 473 (N = 700). These two MS-DRG patient groups were used as the study cohort representing patients who, by definition, did not have serious comor-bidities or complications. Results: Unemployed non-cervical patients tended to stay on average 1.8 days longer in hospital and had on average $5800 higher hospital charges. No major differ-ences were noted in length of stay and hospital cost between government and private insurance patients. However, self-pay non-cervical fusion patients had notable increases in length of stay and hospital cost, especially in the >39 and <60 age group with the difference in length of stay amounting to 5 days and in hospital charges to $10,000. Univariate analysis with DRG (460 or 473) as a covariate showed significant impact from employment status on length of stay (F = 4.259, P = 0.014) and less significant impact from payor category on hospital charges (F = 2.229, P = 0.064) in the economically-productive 40 -59 age group. Conclusions: In general, no increase in hospital resource consumption was noted except among self-pay patients, the same group seemingly least able to afford expensive healthcare. 展开更多
