1XGBoost model for electrocaloric temperature change prediction in ceramics显示文摘An eXtreme Gradient Boosting(XGBoost)machine learning model is built to predict the electrocaloric(EC)temperature change of a ceramic based on its composition(encoded by Magpie elemental properties),dielectric constant,Curie temperature,and characterization conditions.A dataset of 97 EC ceramics is assembled from the experimental literature.By sampling data from clusters in the feature space,the model can achieve a coefficient of determination of 0.77 and a root mean square error of 0.38 K for the test data.Feature analysis shows that the model captures known physics for effective EC materials.The Magpie features help the model to distinguish between materials,with the elemental electronegativities and ionic charges identified as key features.The model is applied to 66 ferroelectrics whose EC performance has not been characterized.Lead-free candidates with a predicted EC temperature change above 2 K at room temperature and 100 kV/cm are identified.Jie Gong Sharon Chu Rohan K.Mehta Alan J.H.McGaughey 2022npj Computational Materials2022,,1:1

3并发症处理Ⅱ:腔道衰竭和腔道气道瘘显示文摘腔道衰竭和腔道气道瘘是食管切除后罕见的并发症,但可导致灾难性的后果,死亡率非常高。存活者的住院时间会延长,期间遭受更多的医疗干预,经历更久的时间来恢复经口进食。高度警惕有助于早期诊断。腔道衰竭常需要一段时间的近端食管转位及阶段性重建。腔道气道瘘可经内镜修复但失败率高,很多患者需要手术修复以关闭瘘口,并且填充血管丰富的组织以减少复发。Shari L.Meyerson Christopher K.Mehta 李云雷 2016中国胸心血管外科临床杂志2016,23,2:1

5Lentil straw(Lens culinaris): An alternative and nutritious feed resource for kids显示文摘The scarcity of feed resources with the continuously increasing cost of usual animal feeds urgently demands searching some alternate feeds for ruminants. In this study, Barberi male kids were divided into4 groups of 5 kids(body weight 17.5 ± 1.8 kg) in each group, and ad libitum fed lentil straw(Lens culinaris;LS), LS based total mixed ration(LSTMR), urea ammoniated LS(ALS) or ALS based total mixed ration(ALSTMR) for a period of 28 days. Results showed LS was a superior feed(CP, 9.2%) for kids, but having quite high crude fibre(CF; 39.6%) and Ca:P ratio(10:1). Urea ammoniation of LS was helpful for increasing the digestible crude protein(DCP)(P < 0.01), nitrogen-free extract(NFE) and total digestible nutrients(TDN) with reduction of CF content. Urea mmoniation also improved the digestibility of neutral and acid detergent fibre(P < 0.01), but its effect on CP digestibility was negative(P < 0.05). Dry matter(DM), DCP and TDN intakes(per kg W0.75) were also improved(P < 0.01) in the kids fed ALS. Negative growth rate and nitrogen(N) balance(-33.8 and -1.4 g/day, respectively) in kids fed LS became positive(46.9 and 2.0 g/day, respectively) when ALS was used in the diets of kids. Feeding of ALS also increased(P < 0.01) the total N and ammonia N content of strained rumen liquor(SRL). Use of straw(LS or ALS) in TMR increased the digestibility of DM, organic matter and NFE(P < 0.01), intake of energy, as well as total volatile fatty acids concentration(P < 0.01) in the SRL. The present study suggested that optimum performance of kids may be achieved using either ALS alone or TMR with LS or ALS.Vishal Mudgal Mukesh K.Mehta Ashok S.Rane 2018Animal Nutrition2018,,4:0
