Gouranga C Nayak ∗ 1 Department of Physics, University of Arizona, Tucson, AZ 85721, USA Abstract In this paper we derive a gauge fixing identity by varying the covariant gauge fixing term in Z[A, J, η, η̄] in the background field method of QCD in pure gauge. Using this gauge fixing identity we establish a relation between Z[J, η, η̄] in QCD and Z[A, J, η, η̄] in background field method of QCD in ...

Automated program fixing consists of generating source code in order to fix bugs in an automated manner. Our intuition is that automated program fixing can imitate humanbased program fixing. Hence, we present a method to mine repair actions from software repositories. A repair action is a small semantic modification on code such as adding a method call. We then decorate repair actions with a pr...

An algorithm for gauge fixing to the minimal Landau gauge in lattice QCD is described. The method, a combination of an evolutionary algorithm with a steepest descent method, is able to solve the problem of the nonperturbative gauge fixing. The performance of the combined algorithm is investigated on 8, β = 5.7, and 16, β = 6.0, lattice SU(3) gauge configurations.

Detecting and fixing defects are key activities in a testing process, which consume two kinds of skill sets. Unfortunately, many current leading software estimation methods, such as COCOMO II, mainly estimate the effort depending on the size of software, and allocate testing effort proportionally among various activities. Both efforts on detecting and fixing defects, are simply counted into sof...

We demonstrate a new method of electrical fixing of waveguiding channels in strontium-barium niobate. The method is applicable to both bulk material and planar SBN waveguides. Waveguiding is achieved for extraordinarily polarized light. We suggest that the fixing is based on a partial depoling of the crystal rather than on internal electric fields.

background: waiting time indicates the feasibility of access to medical services and can be measured as a performance indicator. long waiting times prohibit the provision of good services, waste patients’ time, and jeopardise patient satisfaction. therefore, patients' satisfaction from waiting time plays a significant role in quality assurance and management. methods: in this qualitative study,...
