Background -There are few comparative data regarding long-term nonfatal outcomes for women versus men after coronary artery bypass grafting(cABG). This study compares gender differences in cardiac events in a population of hospital survivors up to 11 years after isolated cABG surgery in Ontario, canada. Methods and Results -A population-based cohort study(n=68 774 patients, 15 043 women) between September 1, 1991, and April 1, 2002, was assembled with linked clinical and administrative databases. cox modeling and propensity score matching were used to compare death, cardiac readmission(angina, heart failure, myocardial infarction), repeat revascularization(angioplasty or cABG), and stroke readmission between men and women. Women were older(65±17 versus 62±13 years), more likely to present with urgent or emergent status(64%versus 56%), and less likely to receive arterial grafts(70%versus 78%). Women had a higher rate of cardiac readmission in the first year after surgery(hazard ratio[HR] of 1.5, 95%confidence interval[cI] 1.36 to 1.56), and this increased risk persisted after 1 year(HR 1.2, 95%cI 1.14 to 1.31). This was primarily due to readmissions for unstable angina(HR 1.3, 95%cI 1.24 to 1.38) and congestive heart failure(HR 1.1, 95%cI 1.06 to 1.21). propensity-matched women had similar rates of death(HR 0.9, 95%cI 0.83 to 0.98) and repeat revascularization(HR 1.0, 95%cI 0.91 to 1.06). conclusions -Women have a more complex clinical preoperative presentation and are more likely to be readmitted with unstable angina and congestive heart failure after cABG but experience survival similar to those seen in men. Gender differences in outcomes may be improved through durable revascularization strategies and close postoperative follow-up.c.re targeted to women.

Here we assess the applicability of graph neural networks(GNNs)for predicting the grain-scale elastic response of polycrystalline metallic *** GNN surrogate models,grain-averaged stresses during uniaxial elastic tension in low solvus high-refractory(LSHR)Ni Superalloy and Ti 7 wt%Al(Ti-7Al)are predicted as example face-centered cubic and hexagonal closed p.c.ed alloys,resp.c.ively.A transfer learning approach is taken in which GNN surrogate models are trained using crystal elasticity finite element method(cEFEM)simulations and then the trained surrogate models are used to predict the mechanical response of microstructures measured using high-energy X-ray diffraction microscopy(HEDM).The performance of using various microstructural and micromechanical descriptors for input nodal features to the GNNs is explored through comparisons to traditional mean-field theory predictions,reserved full-field cEFEM data,and measured far-field HEDM *** effects of elastic anisotropy on GNN model performance and outlooks for the extension of the framework are discussed.

Density functional theory calculations have been performed to investigate the structural, electronic, and cO2adsorption properties of 55-atom bimetallic cu Ni nanoparticles（Nps） in core-shell and decorated architectures,as well as of their monometallic counterparts. Our results revealed that with resp.c. to the monometallic cu55and Ni55parents, the formation of decorated cu12Ni43and core-shell cu42Ni13are energetically favorable. We found that cO2chemisorbs on monometallic Ni55, core-shell cu13Ni42, and decorated cu12Ni43and cu43Ni12,whereas, it physisorbs on monometallic cu55and core-shell cu42Ni13. The presence of surface Ni on the Nps is key in strongly adsorbing and activating the cO2molecule（linear to bent transition and elongation of c=O bonds）. This activation occurs through a charge transfer from the Nps to the cO2molecule, where the local metal d-orbital density localization on surface Ni plays a pivotal role. This work identifies insightful structureproperty relationships for cO2activation and highlights the importance of keeping a balance between Np stability and cO2adsorption behavior in designing catalytic bimetallic Nps that activate cO2.

The objective of this study was to investigate the effects of near-fault ground motions on substandard bridge columns and piers. To accomplish these goals, several large scale reinforced concrete models were constructed and tested on a shake table using near- and far-field ground motion records. Because the input earthquakes for the test models had different characteristics, three different measures were used to evaluate the effect of the input earthquake. These measures are peak shake table acceleration, sp.c.ral acceleration at the fundamental period of the test sp.c.mens, and the sp.c.men drift ratios. For each measure, force-displacement relationships, strains, curvatures, drift ratios, and visual damage were evaluated. Results showed that regardless of the measure of input or response, the near-fault record generally led to larger strains, curvatures, and drift ratios. Furthermore, residual displacements were small compared to those for columns meeting current seismic code requirements.

composite polymer electrolytes（cpEs） comprising poly（vinilydene fluoride-hexafluoro propylene）, pVDF-coHFp and zinc triflate, Zn（cF3SO3）2 with varying concentrations of ZrO_2 nanofillers were prepared by solution casting technique with N,N-dimethyl formamide（DMF） as the common solvent. The polymer electrolyte sp.c.men with the particular composition 75 wt% pVDF-co-HFp： 25 wt% Zn Tf ＋ 7 wt% Zr O2 showed the highest conductivity of 4.6 × 10-4 S/cm at 298 K as confirmed from impedance measurements and favored by the rich amorphous phase of the cpE revealed from room temperature X-ray diffraction analysis（XRD）. The electrical conductivity relaxation time and its distribution within the materials have been evaluated from the electric modulus M 2 and impedance Z＂ data which showed the occurrence of non-Debye type of relaxation phenomenon. The changes in the surface morphology of the cpEs were examined using scanning electron microscopy（SEM）. The electrochemical stability window of cpE is found to be 2.6 V with a thermal stability up to 300 °c. An electrochemical cell has been fabricated based on Zn/MnO_2 electrode couple under a constant load of 1 MΩ and its discharge characteristics have been evaluated.

尽管已有大量针对非急诊、门诊高血压的远期预后及治疗方案的研究,但对急诊高血压,尤其是无明显靶器官损害的急诊高血压的相关研究却很少,缺乏高血压急诊患者短期及长期预后的研究。一份发表于1967年的研究是少数对急诊高血压患者短、长期预后进行调查的研究之一,结果显示：在143例舒张压显著升高[115~129 mm Hg（1mm Hg=0.133kpa）]并随机分配至降压治疗组或安慰剂组的男性患者中，安慰剂组有21例患者出现高血压并发症或死亡，而降压治疗组则均未发现上述情况。

The proximate, micronutrient and amino acid profile of roasted and germinated breadnut seed flour were evaluated. Fresh mature fruits (1.5 kg) of breadnut were purchased from Relief market in Imo State, Nigeria. The breadnut seeds were divided into three portions for different unit operations, namely raw, roasted and germinated. Samples were analyzed for proximate, minerals and amino acids compositions. Statistical significance was set at p protein (13.80%) and fat (7.90%) content were significantly higher (p cantly higher (p carbohydrate (75.85%) and moisture (11.05%) were significantly higher (p cronutrient composition shows that iron (74.35 mg/100g) was higher in roasted breadnut seed, phosphorous (12.95 mg/100g) and zinc (30.4 mg/100g) were higher in germinated breadnut seed flour while calcium (0.04%), magnesium (0.05%), vitamin A (0.27%) and vitamin c (0.85%) were higher in raw breadnut. All the essential amino acids except norleucine were present in the breadnut in varying quantities. Between roasting and germination, essential acids;valine cine ptophan were more in germinated breadnut seeds while leucine phenylalanine processing breadnut seeds. The use of breadnut seed flours as composite flour in food production may help to provide protein and micronutrient among the vulnerable groups.
