We report a joint experimental and theoretical study of CO chemisorption on the golden cages. We find that the Au(17)(-) cage is highly robust and retains its cage structure in Au(17)(CO)(-). On the other hand, the Au(16)(-) cage is transformed to a structure similar to Au(17)(-) upon the adsorption of CO. Au(18)(-) is known to consist of two nearly degenerate structures, i.e., a cage and a pyr...

A (k; g)-cage is a graph of minimum order among k-regular graphs with girth g. We show that for every cutset S of a (k; g)-cage G, the induced subgraphG[S] has diameter at least bg/2c, with equality only when distance bg/2c occurs for at least two pairs of vertices in G[S]. This structural property is used to prove that every (k; g)-cage with k ≥ 3 is 3-connected. This result supports the conje...

Cage-based deformation techniques are widely used to control the deformation of an enclosed fine-detail mesh. Achieving deformation based on vertex constraints has been extensively studied for the case of pure meshes, but few works specifically examine how such vertex constraints can be used to efficiently deform the template and estimate the corresponding cage pose. In this paper, we show that...

When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage pr...

In this paper i, j, k, n denote natural numbers. Next we state several propositions: (1) For all subsets A, B of E T such that A is Bounded or B is Bounded holds A ∩ B is Bounded. (2) For all subsets A, B of E T such that A is not Bounded and B is Bounded holds A \ B is not Bounded. (3) For every compact connected non vertical non horizontal subset C of E2 T holds (W-min L̃(Cage(C, n))) " Cage(C...

A variety of force field based simulations have been used to study the location and diffusion of benzene adsorbed in a model zeolite HY (Si/Al ) 2.43), namely: molecular docking; equilibrium and nonequilibrium molecular dynamics; and Monte Carlo umbrella sampling. Multiple adsorption sites are found, with benzene facially coordinated to one or two H(1) or H(2) protons in the supercage. Some sli...

background: cervical spine sustains most of thevertebral column injuries, among other injuries, the disc degeneration and damage that lead to replacement of the damaged disc with cage or artificial disc. methods: the c4 to c6 vertebrae of a normal subject and a person with interbody fusion cage were 3d modelled and then analyzed using finite element method. the results of maximum stress and str...

BACKGROUND & OBJECTIVES CAGE-AID questionnaire is a short, useful screening tool for substance dependence. Assessment of one family member for the screening of substance dependence in the family could be useful in clinical practice and research. In this study, we aimed to assess the validity of the Family CAGE-AID questionnaire for the diagnosis of substance dependence. METHODS Cross-sectiona...
