We study the phase diagram at T = 0 of the antiferromagnetic Heisenberg model on the triangular lattice with spatially-anisotropic interactions. For values of the anisotropy very close to Jα/Jβ = 0.5, conventional spin wave theory predicts that quantum fluctuations melt the classical structures, even for arbitrary values of S. From the limit of weakly coupled chains, Jβ << Jα, it is shown that ...
Transforaminal pelvic fractures are high-energy injuries that are translationally and rotationally unstable. This study compared the biomechanical stability of triangular osteosynthesis vs 2-transsacral-screw fixation in the repair of a transforaminal pelvic fracture model. A transforaminal fracture model was created in 10 cadaveric lumbopelvic specimens. Five of the specimens were stabilized w...
Sensitive questions about people’s behaviors are often discussed in studies in the fields of human, social, and medical sciences. Obtaining valid answers to these kinds of questions is one of the main challenges in the mentioned studies. The most important risk factors for the validity of these studies are response bias and non-response bias, which occur because of concerns about divulging pe...
this paper deals with ridge estimation of fuzzy nonparametric regression models using triangular fuzzy numbers. this estimation method is obtained by implementing ridge regression learning algorithm in the la- grangian dual space. the distance measure for fuzzy numbers that suggested by diamond is used and the local linear smoothing technique with the cross- validation procedure for selecting t...
