This work, conceptually envisaged by Prof. R. B. Fisher, undertook the augmentation of one of the original approaches in the dense stereo eld by Cox et al. [1]. The aim was to introduce explicit vertical constraint into the Cox algorithm and reduce the streaking and speckling noise e ects commonly associated with stereo results from this approach. These e ects are commonly attributed to the lac...

A bowl-shaped nitrogen-doped nanographene composed of a pyrrolo[3,2-b]pyrrole core substituted with six arene rings circularly bonded one another undergoes bowl-to-bowl inversion low barrier. This resembles that an umbrella flipped by the strong wind. The transition state is not planar, but possesses rather twisted, S-shaped conformation Ci symmetry. bowl-inversion mechanism follows quadruple-w...

The electronic states occurring in a double vacancy defect for graphene nanoribbons have been calculated in detail based on a pyrene model. Extended ab initio calculations using the MR configuration interaction (MRCI) method have been performed to describe in a balanced way the manifold of electronic states derived from the dangling bonds created by initial removal of two neighboring carbon ato...

We classify coproducts on matrix algebra in terms of solutions to some modification of pentagon equation. The construction of Baaj and Skan-dalis describing finite dimensional unitary solutions of pentagon equation is extended to the non-unitary case. We establish the relation between Hopf-Galois algebras and solutions to modified pentagon equation.

Abstract The complementary prism $$\Gamma {\bar{\Gamma }}$$ Γ ¯ is constructed from the disjoint union of a graph $$ and its complement $${\bar{\Gamma if an edge added between each pair identical vertices in . It generalizes Petersen graph, whic...

a r t i c l e i n f o Scanning tunneling microscopy shows that a layer of graphene can be grown on the hex-reconstructed Pt (100) surface and that the reconstruction is preserved after growth. A continuous sheet of graphene can be grown across domain boundaries and step edges without loss of periodicity or change in direction. Density functional theory calculations on a simple model system supp...

Various types of multiple vacancies (MVs) in graphene nanoribbons (GNRs) and graphene are explored by quantum calculations. It is surprising that their relative stabilities highly depend on the width of the GNRs and thus is significantly different from those in graphene. A diagram of various MVs in GNRs is drawn and it is predicated that the hole in both GNRs and graphene can be annihilated. A ...

A new method for evaluating hand preshaping during reaching-to-grasp movement is proposed. The method makes use of all five fingers in estimation of prehension. The investigation was performed on six healthy subjects grasping three different objects at various positions and orientations. The objects were presented to the subjects by means of a robot, which also induced perturbations in both obj...
