However, it is a challenge to screen out the suitable composition from the diverse combinations. Referring to the prototype AuCu3 with AB3-L12 structure, where it becomes a face-centered cubic (fcc) structure if element A and B are the same element, the site occupying tendencies of the elements and thermodynamic functions are predicted by using the sublattice model supported with first-principles total energy calculations. By considering the Gibbs energy of formation and the configurational entropy, the fcc HEAs in available literatures are examined, and the results of the quinary system with equal-atomic composition CoFeMnNiM and the hexbasic system with equal-atomic composition CoFeMnNiSmM are reported, respectively, where the element M is selected from the rest of the periodical table. When M =Cr, Zn, Ru, Rh, Pd, Re, Os, Ir, or Pt in the quinary systems CoFeMnNiM and when M =Ru, Pd, or Pt in the hexbasic systems CoFeMnNiSmM , respectively, the alloys are recommended to be potential fcc HEAs. The new approach opens a new way to mine the rich ores of HEAs.

The most important and effective way to reduce VTE incidence is to identify the patients at risk and give necessary prevention. VTE is a multifactorial and complicated disorder. Major risk factors for VTE include surgery and trauma, acute medical illness, active cancer and pregnancy. Genetic factors increase susceptibility to the disease and are useful in predicting the development of VTE. Gene-gene and gene-environment interactions alter and magnify the clinical picture in this disorder. This brief review summarizes some selected clinical and genetic risk factors for VTE based on the current research in China.

It is assumed that several moving targets are on the plane and may interfere with each other if they chirp simultaneously. Extended Kalman filters to estimate the positions of all moving targets are run in a centralized computer based on intermittently available distance measurement from the reference nodes. A myopic scheduling scheme together with a grouping approach are proposed to improve tracking accuracy and avoid interference. Two metric functions are used in myopic scheduling, namely, MEE and MAED. The simulations show that MEE may cause over-partiality which leads to bad tracking accuracy for some targets, and MAED can effectively eliminate such over-partiality. Myopic scheduling schemes with both MEE and MAED are realized on the Cricket platform based on active architecture. The experiment results show that active architecture results in better tracking performance than passive architecture for tracking a small number of moving targets. Also, it is shown that in active architecture myopic schemes with both MEE and MAED have better tracking performance than a periodic scheme.

Methods:Twenty-three cases of massive pulmonary embolism were analyzed retrospectively. The pulmonary artery obstruction index and the right ventricular function parameters were collected and analyzed on CTPA before thrombolytic therapy, 24 hours and 14 days after therapy, respectively. Results:The pulmonary artery obstruction index decreased gradually, and there was significant difference before therapy, 24 hours and 2 weeks after therapy. Twenty-four hours after therapy, the maximal short axes diameter and the maximal transverse area of right ventricle(RV d , RV s ) decreased significantly, the maximal short axes diameter and the maximal transverse area of left ventricle(LV d , LV s ) increased significantly, and the RV d /LV d , RV s /LV s decreased apparently. The pulmonary artery symbolic pressure before and 24 hours after therapy were apparently different. There was no significant difference between azygos vein, the super vena cava, the main pulmonary artery and vein reflux before and after therapy. Conclusion:CTPA can evaluate the pulmonary artery obstruction degree and right ventricular function dynamically.

Methods:Thirty-six patients with CTPA-confirmed PE who underwent ultrasonic cardiography(UCG) within the ensuing 24 hours were retrospectively reviewed. According to the severity of the disease, the patients were divided into the massive PE group(24 cases) and non-massive PE group(12 cases) respectively. CT scans were analyzed for findings suggestive of RVD. Scans were considered positive for RVD if the right ventricle was dilated(RV d /LV d 1) or if the interventricular septum was straightened or deviated towards the left ventricle. Results were then compared with the results of UCG to estimate the value of CTPA in detecting RVD associated with PE. Results:In all cases, compared with UCG, the diagnostic sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, and negative predictive value of CTPA was 84.61%, 78.26%, 3.892, 0.197, 68.75% and 90% respectively. Kappa value was 0.60, which suggested moderate agreement between CTPA and UCG in the whole level. In the massive PE group, the diagnostic sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value, negative predictive value of CTPA was 84.61%, 72.73%, 3.103, 0.212, 78.57% and 80% respectively. Kappa value was 0.58, which suggested moderate agreement between CTPA and UCG in the massive PE group. In the non-massive PE group, the diagnostic specificity of CTPA was 83.33%. By statistics, the value of RV d /LV d had significant difference between the massive PE and the non-massive PE group. Conclusion:CTPA can reliably detect RVD through the evaluation of cardiac morphology. However, this result requires confirmation using a larger prospective cohort study.

The results show that the stresses and strains in such concrete and steel rings are uneven; the curves of strains and stresses change gradually around the interface. To ease numerical computation, the mechanical system was simplified under the assumptions of synchronous deformation and uniform strains and stresses. The results of the numerical simulation and simplified stress calculation can match almost perfectly. It means that the simplified mechanical model can be used in stress and visco-elastic behavior quantification.

In addition, chromatin organization may be governed in part by interactions with structural components of the nucleus. The nuclear lamins comprise the lamina and a variety of nucleoplasmic assemblies that together are major structural components of the nucleus. Furthermore, lamins and lamin-associated proteins have been reported to bind chromatin. These observations suggest that the nuclear lamins may be involved in the regulation of gene activity. In this report, we test this possibility by disrupting the normal organization of nuclear lamins with a dominant negative lamin mutant lacking the NH2-terminal domain. We find that this disruption inhibits RNA polymerase II activity in both mammalian cells and transcriptionally active embryonic nuclei from Xenopus laevis. The inhibition appears to be specific for polymerase II as disruption of lamin organization does not detectably inhibit RNA polymerases I ...

The CGI temporal template encodes the temporal information among gait frames via color mapping to improve the recognition performance. Our method starts with the extraction of the contour in each gait image, followed by utilizing a color mapping function to encode each of gait contour images in the same gait sequence and compositing them to a single CGI. We also obtain the CGI-based real templates by generating CGI for each period of one gait sequence and utilize contour distortion to generate the CGI-based synthetic templates. In addition to independent recognition using either of individual templates, we combine the real and synthetic temporal templates for refining the performance of human recognition. Extensive experiments on the USF HumanID database indicate that compared with the recently published gait recognition approaches, our CGI-based approach attains better performance in gait recognition with considerable robustness to gait period detection.

An image coding approach is proposed in which a number of regions of the input image are skipped at the encoder and are recovered through the inpainting process at the decoder. Furthermore, a structure-aware inpainting (SAI) method is developed to restore the skipped structural regions by taking advantage of the available portion of the decoded image. A binary structure map is extracted and compressed into the generated bit-stream to indicate the skipped regions with salient structures. By making use of the decoded texture information together with the structure map, the SAI method can recover the skipped structural regions as well as the non-structural ones effectively at the decoder. Compared with JPEG, our proposed image compression scheme allows smaller file, with the potential of up to 50% bit-saving capability, at similar visual quality levels.

The large diameter and length of TSVs, as compared to traditional interconnects, create some unique process challenges. Via plating and chemical-mechanical polishing (CMP) processes used in standard copper interconnect technology are generally not suitable for TSV fabrication.

Studies in cultured cells showed an association between PNC and transformed phenotype. To evaluate the relationship between structure and malignancy in vivo, we examined PNC prevalence (the percentage of cells containing at least one PNC) in normal and cancerous paraffin-embedded breast tissues using immunohistochemistry against a PNC-associated protein. Five hundred nuclei in the most active area of each sample were scored for PNC prevalence. The results show that PNC prevalence significantly correlates with the progression of breast cancer (by the criteria of staging). PNC prevalence in primary tumors, lymph nodes, and distant metastases shows a stepwise increase from a median of 23% in primary tumors to approximately 100% in distant metastases. In addition, univariate and multivariate (controlling for tumor size and grade) analyses show...
