Vacancy formation and oxidation characteristics of single layer TiS3
(American Chemical Society, 20150514)The structural, electronic, and magnetic properties of pristine, defective, and oxidized monolayer TiS3 are investigated using firstprinciples calculations in the framework of density functional theory. We found that a ... 
Vacuum energy as the origin of the gravitational constant
(Springer, 200911)We develop a geometrodynamical approach to the cosmological constant problem (CCP) by invoking a geometry induced by the energymomentum tensor of vacuum, matter and radiation. The construction, which utilizes the dual ... 
Valorization of wheat bran for the production of polygalacturonase in SSF of Aspergillus sojae
(Elsevier, 201403)Wheat bran, among various agro industrial by products, screened for the production of polygalacturonase (PG) in solidstate fermentation of Aspergillus sojae mutant strain, was found to be the most suitable substrate without ... 
Vapor phase solvatochromic responses of polydiacetylene embedded matrix polymers
(Royal Society of Chemistry, 2017)The solvatochromic response of polydiacetylene (PDA) in the vapor phase is enabled upon incorporation with matrix polymers such as polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), polyacrylic acid (PAA), and ... 
Variant concept of transportationdisadvantaged: Evidence from Aydın, Turkey, and Yamaga, Japan
(American Society of Civil Engineers, 2011)Transportationdisadvantaged groups have been defined in previous studies as those who are low income earners, are family dependent, have limited access to private motor vehicles and public transport services, and are ... 
Variations on a theme of qoscillator
(IOP Publishing, 20150701)We present several ideas in the direction of physical interpretation of q and foscillators as nonlinear oscillators. First we show that an arbitrary onedimensional integrable system in actionangle variables can be ... 
Varietal classification and prediction of chemical parameters of Turkish wines by in frared spectroscopy

Vascularization for cooling and reduced thermal stresses
(Elsevier, 201501)This paper documents the effect of thermal expansion on a vascularized plate that is heated and loaded mechanically. Vascular cooling channels embedded in a circular plate provide cooling and mechanical strength. The coolant ... 
Vector modal solution of evanescent coupler
(IEEE, 199712)We present a vector modal solution for the evanescent coupler comprising an optical fiber and a slab waveguide. We identify the normal vector ridge modes of the device for different configurations. The dispersion characteristics ... 
Vector shock soliton and the Hirota bilinear method
(Elsevier, 200510)The Hirota bilinear method is applied to find an exact shock soliton solution of the system reactiondiffusion equations for ncomponent vector order parameter, with the reaction part in form of the third order polynomial, ... 
Vertex coloring of a graph
(İzmir Institute of Technology, 2004)Vertex coloring is the following optimization problem; given a graph, how many colors are required to color its vertices in such a way that no two adjacent vertices receive the same color? The required number of colors is ... 
Vertexdecomposable graphs, codismantlability, cohenmacaulayness, and castelnuovomumford regularity
(Electronic Journal of Combinatorics, 201401)We call a vertex x of a graph G = (V, E) a codominated vertex if NG[y] ⊆ NG[x] for some vertex y ∈ V \{x}, and a graph G is called codismantlable if either it is an edgeless graph or it contains a codominated vertex x such ...
