Periprosthetic joint infections are devastating complications that are difficult and expensive to treat and have a substantial mortality rate. A major goal of modern joint arthroplasty is to minimize these infections. Preoperative factors associated with increased risk of infection include malnutrition, diabetes mellitus, obesity (body mass index.40 kg/m2), and rheumatoid arthritis. Administrat...

Properdin factor D,1 a 23,500 tool wt euglobulin (6), interacts with properdin factor B and cobra venom factor (CoVF) to generate the CoVF-dependent C3 convertase which cleaves C3 (7) and activates the terminal complement components, C5-C9 (8). Fluid phase C3b, the major cleavage fragment of C3, interacts with factors B and D in a manner analogous to CoVF to form a fluid phase C3b-dependent C3 ...

The purpose of this expository lecture is to explain the basic ideas underlying the final resolution of “Fermat’s Last Theorem” after 356 years as a consequence of the reported establishment by Andrew Wiles of a sufficient portion of the “Shimura-Taniyama-Weil” conjecture. As these notes are being written, the work of Wiles is not available, and the sources of information available to the autho...

Recently Z. S. Zhang et al [Phys. Lett. A 356(2006)199] have proposed an one-way quantum identity authentication scheme and claimed that it can verify the user’s identity and update securely the initial authentication key for reuse. In this paper we will show that, under an eavesdropper’s intercept-measure-resend attack, Zhang et al’s scheme is only a one-time-use scheme for the updated key can...

آلیاژهای منیزیم معمولاً دارای عدم تقارن تسلیم در حالت کشش و فشار هستند که این عامل ناشی از سازوکارهای مختلف تغییر شکل پلاستیک فعال تحت بارگذاری‌های کششی فشاری است. مقاله بر روی شبیه‌سازی المان حجمی نماینده‌ی سه‌بعدی آلیاژ اکسترود شده تمرکز دارد تا با کمک روابط کریستال پلاستیسیته تأثیر شدت بافت پایه ـ را بررسی کند. پلاستیسته مبتنی‌بر لغزش به‌صورت یک زیربرنامه نرم‌افزار آباکوس (U‌M‌A‌T) برای آزمون...

In this paper, motivated and inspired by Zegeye and Shahzad (Nonlinear Anal. 70:2707-2716, 2009), Qin et al. (J. Comput. Appl. Math. 225(1):20-30, 2009) and Kimura and Takahashi (J. Math. Anal. Appl. 357:356-363, 2009), we introduce a new hybrid projection iterative scheme that converges strongly to a common element of the solution set of a generalized mixed equilibrium problem, the solution se...

The use of linear models to discriminate between primary and secondary assortative mating has allowed a significant advance in our understanding of the mate selection process. We describe how these methods may be implemented in the LISREL and COSAN packages and illustrate the method with data on cognitive ability, education, and personality reported by Phillips et al. (Behav. Genet. 18:347-356,...
