OBJECT Several techniques for the surgical stabilization of the atlas and the axis have been described. Placement of C-1 lateral mass screws is one of the latest technical advances, and has gained popularity due to its efficacy and biomechanical advantages. However, the technique for placement of C-1 lateral mass screws, as first described by Harms, can cause excessive bleeding or irritation of...

The aim of this work is to improve the accuracy of cold stamping product by accommodating springback. This is a numerical approach to improve the accuracy of springback analysis and die compensation process combining the displacement adjustment (DA) method and the spring forward (SF) algorithm. This alternate hybrid method (HM) is conducted by firstly employing DA method followed by the SF meth...

The need for venting the heart during cardiopulmonary bypass has been the topic of continued debate. Potential disadvantages and drawbacks have been noted with traditional modes for venting. A technique for venting the heart is presented using a pulmonary artery catheter. The relative advantages and merits of this approach are discussed.

In this study, the progressive collapse response of reinforced concrete buildings designed for ‘government buildings’ occupancy class was investigated numerically. For purpose, two framed were initially according to Turkish Earthquake Code published in 2018. Later, those responses evaluated using Alternate Path direct design approach defined GSA-2016 and UFC 4-023-03 guidelines. Three different...

In this paper I develop a new computational method for pricing path dependent options. Using the path integral representation of the option price, I show that in general it is possible to perform analytically a partial averaging over the underlying risk-neutral diffusion process. This result greatly eases the computational burden placed on the subsequent numerical evaluation. For short-medium t...

This paper proposes a framework for the constitutive model based on the semi-micromechanical aspects of plasticity, including damage progress for simulating behavior of concrete under multiaxial loading. This model is aimed to be used in plastic and fracture analysis of both regular and reinforced concrete structures, for the framework of sample plane crack approach. This model uses multilamina...
