1The Open Quantum Materials Database (OQMD): assessing the accuracy of DFT formation energies显示文摘The Open Quantum Materials Database(OQMD)is a high-throughput database currently consisting of nearly 300,000 density functional theory(DFT)total energy calculations of compounds from the Inorganic Crystal Structure Database(ICSD)and decorations of commonly occurring crystal structures.To maximise the impact of these data,the entire database is being made available,without restrictions,at www.oqmd.org/download.In this paper,we outline the structure and contents of the database,and then use it to evaluate the accuracy of the calculations therein by comparing DFT predictions with experimental measurements for the stability of all elemental ground-state structures and 1,670 experimental formation energies of compounds.This represents the largest comparison between DFT and experimental formation energies to date.The apparent mean absolute error between experimental measurements and our calculations is 0.096 eV/atom.In order to estimate how much error to attribute to the DFT calculations,we also examine deviation between different experimental measurements themselves where multiple sources are available,and find a surprisingly large mean absolute error of 0.082 eV/atom.Hence,we suggest that a significant fraction of the error between DFT and experimental formation energies may be attributed to experimental uncertainties.Finally,we evaluate the stability of compounds in the OQMD(including compounds obtained from the ICSD as well as hypothetical structures),which allows us to predict the existence of~3,200 new compounds that have not been experimentally characterised and uncover trends in material discovery,based on historical data available within the ICSD.Scott Kirklin James E Saal Bryce Meredig Alex Thompson Jeff W Doak Muratahan Aykol Stephan Rühl Chris Wolverton 2015npj Computational Materials2015,,1:62

4The dependences of osteocyte network on bone compartment, age, and disease显示文摘Osteocytes, the most abundant bone cells, form an interconnected network in the lacunar-canalicular pore system(LCS) buried within the mineralized matrix, which allows osteocytes to obtain nutrients from the blood supply, sense external mechanical signals, and communicate among themselves and with other cells on bone surfaces. In this study, we examined key features of the LCS network including the topological parameter and the detailed structure of individual connections and their variations in cortical and cancellous compartments, at different ages, and in two disease conditions with altered mechanosensing(perlecan deficiency and diabetes).LCS network showed both topological stability, in terms of conservation of connectivity among osteocyte lacunae(similar to the ‘‘nodes' ' in a computer network), and considerable variability the pericellular annular fluid gap surrounding lacunae and canaliculi(similar to the ‘‘bandwidth'' of individual links in a computer network). Age, in the range of our study(15–32 weeks), affected only the pericellular fluid annulus in cortical bone but not in cancellous bone. Diabetes impacted the spacing of the lacunae, while the perlecan deficiency had a profound influence on the pericellular fluid annulus. The LCS network features play important roles in osteocyte signaling and regulation of bone growth and adaptation.Xiaohan Lai Christopher Price Shannon Modla William R Thompson Jeffrey Caplan Catherine B Kirn-Safran Liyun Wang 2015Bone Research2015,3,2:6
5澳大利亚肉类标准和分级体系显示文摘澳大利亚肉类标准(meat standards Australia,MSA)是一个肉类全面质量管理系统,旨在为消费者提供一个肉类食用品质的准确描述。MSA已经通过对消费者进行大规模的品尝实验,确定了牛肉供应链中影响牛肉可口性的生产、屠宰、加工和价值以及各个生产环节的关键控制点(critical control points,CCPs)评分。这些关键控制点评分通过两种方式管理牛肉的可口性。首先,屠宰加工领域的关键控制点一直作为胴体评分的强制性标准;其次,其他生产和加工领域的关键点控制评分被合并到一个模型当中,用来预测不同个体肌肉和烹饪技巧的可口性。MSA模型可以用来支持新的营销创新。已经有充分的证据表明,消费者愿意为优质牛肉付出高价。目前已出现几个零售的例子采用MSA可口性评分来给牛肉定价。这样胴体价值的计算方法即为每块零售肉质量乘以不同质量评分的价格,并按照零售价的比例支付牛肉生产者。该系统可以用不同的胴体性状相关的经济权重来计算。由于等级是基于持续的质量规模,生产者在这个系统中的质量和产量方面即便小有增加,也会获得相应的经济回报。MSA系统已经支撑了一个新的和创新的营销系统,该系统的定价是透明的,可以帮助生产者对肉品的质量和产量的调整作出明智的决定。MSA系统不仅在澳大利亚有效地用于预测牛肉的可口性,而且在其他国家也都证明了其应用的有效性。在欧洲启动的ProSafeBeef项目也表明,欧洲也可用类似MSA的系统进行肉类的分级。R POLKINGHORNE J M THOMPSON J F HOCQUETTE D W PETHICK 霍云龙 孟庆祥 2015肉类研究2015,29,2:6
6Gynecologic oncologists involvement on ovarian cancer standard of care receipt and survival显示文摘AIM:To examine the influence of gynecologic oncolo-gists(GO) in the United States on surgical/chemotherapeutic standard of care(SOC), and how this translates into improved survival among women with ovarian cancer(OC).METHODS: Surveillance, Epidemiology, and End Result(SEER)-Medicare data were used to identify 11688 OC patients(1992-2006). Only Medicare recipients with an initial surgical procedure code(n = 6714) were included. Physician specialty was identified by linking SEER-Medicare to the American Medical Association Masterfile. SOC was defined by a panel of GOs. Multivariate logistic regression was used to determine predictors of receiving surgical/chemotherapeutic SOCand proportional hazards modeling to estimate the effect of SOC treatment and physician specialty on survival. RESULTS: About 34% received surgery from a GO and 25% received the overall SOC. One-third of women had a GO involved sometime during their care. Women receiving surgery from a GO vs non-GO had 2.35 times the odds of receiving the surgical SOC and 1.25 times the odds of receiving chemotherapeutic SOC(P < 0.01). Risk of mortality was greater among women not receiving surgical SOC compared to those who did [hazard ratio = 1.22(95%CI: 1.12-1.33), P < 0.01], and also was higher among women seen by non-GOs vs GOs(for surgical treatment) after adjusting for covariates. Median survival time was 14 mo longer for women receiving combined SOC. CONCLUSION: A survival advantage associated with receiving surgical SOC and overall treatment by a GO is supported. Persistent survival differences, particularly among those not receiving the SOC, require further investigation.Sun Hee Rim Shawn Hirsch Cheryll C Thomas Wendy R Brewster Darryl Cooney Trevor D Thompson Sherri L Stewart 2016World Journal of Obstetrics and Gynecology2016,5,2:3
7澳大利亚MSA体系:通过食用品质评价牛肉品质显示文摘<正>澳大利亚肉类标准(MSA)是一个质量管理体系,旨在为消费者提供牛肉食用品质的准确描述。MSA分级系统中,消费者品尝的感官效果被用来描述牛肉的可口性。简单来讲,未经培训的消费者采用0~100直线标度的方法对牛肉样品的嫩度、多汁性、风味和总体接受度进行测试打分,包括下列语言叙述:不满意等级(无评分级)、普通级(或3星级)、良好级(或4星级)、优级(或5星级)。然后对4个感官指标通过权重换算。Pethick D W olkinghorne R P Thompson J M 吴鑫 2015中国畜牧杂志2015,51,S1:2
