This paper has calculated the energy levels of 185-187-189Os isotopes using projected shell model (PSM). Yrast Spectrum, nucleus rotation frequency and ratio reduced electromagnetic transition probabilities, B(E2)/B(M1) plots versus spin for understanding structure multi-quasiparticle band up to spins 47/2+, 33/2+ 31/2+ these isotopes, are plotted, respectively. It was found that in ranges 35/2...
The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...
BACKGROUND The purpose of this study was to report findings of exploratory arthroscopic assessment performed in conjunction with removal of internal fixation device placed in the initial surgery for rotational ankle fracture. METHODS A total of 53 patients (33 male, 20 female) who underwent surgery for rotational ankle fracture between November 2002 and February 2008 were retrospectively revi...
The Mn-matrix was defined by Mohan [20] in which he has shown a method of constructing (1,-1)-matrices and studied some of their properties. The (1,-1)-matrices were constructed and studied by Cohn [5],Wang [33], Ehrlich [8] and Ehrlich and Zeller[9]. But in this paper, while giving some resemblances of this matrix with Hadamard matrix, and by naming it as M-matrix, we show how to construct par...
Although the principle of using x-rays for diagnostic imaging has been known for a long time, there is still a lot of research and improvements going on in the field. One recent addition to the neuro-vascular imaging system—used for visualizing blood vessels in the brain and guidance of interventions—is 3D rotational angiography (3D-RA). Using 3D-RA, it is possible to view the vessel tree in 3D...
In this paper, we introduce a new focusing technique for localization of wideband signals. Relaxing the unitary assumption for the focusing matrices, we formulate the least-square (LS) and the total least-square (TLS) coherent signal-subspace methods. The TLS is an alternative to the conventional LS and uses the fact that the errors can exist both in the focusing location matrix as well as in t...
PURPOSE The aim of this study is to determine the inter-fractional motion of cervical spine in radiotherapy (RT). MATERIALS AND METHODS Eleven localized head and neck cancer patients who were treated from April 2014 to September 2015 were evaluated. Every patient underwent 3 times of computed tomography (CT) simulation with equivalent setting. Left-right (LR, x) and antero-posterior (AP, z) d...
Fibrin has been long used clinically for hemostasis and sealing, yet extension of use in other applications has been limited due to its relatively rapid resorption in vivo, even with addition of aprotinin or other protease inhibitors. We report an engineered aprotinin variant that can be immobilized within fibrin and thus provide extended longevity. When recombinantly fused to a transglutaminas...
Based on the first-order shear deformation theory, a 3-node co-rotational triangular finite element formulation is developed for large modeling of non-smooth, folded and multi-shell laminated composite structures. The two smaller components mid-surface normal vector shell at node are defined as nodal rotational variables in local coordinate system. In global system, one vector, together with sm...
