(Background) Empirical evidence shows that dependency cycles among software components are pervasive in real-life software systems, although such cycles are known to be detrimental to software quality attributes such as understandability, testability, reusability, build-ability and maintainability. (Research Goals) Can the use of extended object-oriented metrics make us better understand the re...
A stable and antifouling electrochemical biosensor based on a designed cyclic peptide was developed for COVID-19 antigen testing in human blood.
PURPOSE The purpose of this study was to assess the biomechanical performance of the long head of the biceps tenodesis with an interference screw with respect to screw depth. METHODS Twenty-one human cadaveric shoulders were randomized into 3 treatment groups (7 each): interference screw placed flush to the humeral cortex, 50% proud, or fully recessed. Bone density was determined, and subpect...
در اکثر ماشین آلات صنعتی دیسک های دوار در دماهای خزش (نیروگاه های اتمی و صنایع تبدیل انرژی) اهمیت بسیار زیادی دارند. اصولاً برخی از دیسک ها دارای ناخالصی می باشند لذا تخمین عمر آنها دیگر بر اساس دیاگرام های استاندارد در asme و غیره قابل اطمینان نمی باشد، لذا برای بررسی شکست نیاز به دانستن پارامتر پار گی خزش به نام c* می باشد، که شبیه پارامتر شکست در مکانیک شکست مانند j است. در این پروژه سعی شده ...
finite affine groups are given by groups of translations and di-lations on finite cyclic groups. for cyclic groups of prime orderwe develop a time-scale (wavelet) analysis and show that for alarge class of non-zero window signals/vectors, the generatedfull cyclic wavelet system constitutes a frame whose canonicaldual is a cyclic wavelet frame.
Cyclic Cushing's syndrome (CS) is a rare disorder, characterized by repeated episodes of cortisol excess interspersed by periods of normal cortisol secretion. The so-called cycles of hypercortisolism can occur regularly or irregularly with intercyclic phases ranging from days to years. To formally diagnose cyclic CS, three peaks and two troughs of cortisol production should be demonstrated. Our...
The physical effects of fatigue failure caused by cyclic strain are important and for most materials well understood. However, nothing is known about this mode of failure in living cells. We developed a novel method that allowed us to apply controlled levels of cyclic displacement to networks of osteocytes in bone. We showed that under cyclic loading, fatigue failure takes place in the dendriti...
