In the present paper we consider the bouncing braneworld scenario, in which the bulk is given by a five-dimensional charged AdS black hole spacetime with matter field confined in a D 3 brane. Then, we study the stability of solutions with respect to homogeneous and isotropic perturbations. Specifically, the AdS black hole with zero ADM mass and charge, and open horizon is an attractor, while th...

We report infrared studies of the Landau level (LL) transitions in single layer graphene. Our specimens are density tunable and show in situ half-integer quantum Hall plateaus. Infrared transmission is measured in magnetic fields up to B=18 T at selected LL fillings. Resonances between hole LLs and electron LLs, as well as resonances between hole and electron LLs, are resolved. Their transition...

PURPOSE To describe the clinical course of a patient with a Boston Keratoprosthesis type I who developed a localized posterior pole retinal detachment secondary to a macular hole. OBSERVATIONS A 73-year-old patient with a Boston Keratoprosthesis developed a localized posterior pole retinal detachment secondary to a macular hole. The retinal detachment was repaired with a 23-gauge pars plana v...

Forty-four rabbits were operated on when five weeks old; in one group a 2 mm drill-hole was made in the intercondylar portion of the right femur across the central portion of the growth plate up to the diaphysis, while in the other group a similar drill-hole of 3.2 mm was made. At 3, 6, 12 and 24 weeks after operation, specimens from the growth plates of both femora were analysed using radiogra...

Black hole attack is one kind of routing disturbing attacks and can bring great damage to all clusters of a MANET. Security remains a major challenge for these networks due to their features of open medium, dynamically changing topologies, and infrastructure-less property. As a result, an efficient algorithm to detect black hole attack is important. This paper proposes and evaluates strategies ...

For a map S : X → X and an open connected set (= a hole) H ⊂ X we define JH(S) to be the set of points in X whose S-orbit avoids H. We say that a hole H0 is supercritical if (i) for any hole H such that H0 ⊂ H the set JH(S) is either empty or contains only fixed points of S; (ii) for any hole H such that H ⊂ H0 the Hausdorff dimension of JH(S) is positive. The purpose of this note is to complet...

The first synthesis of endohedral fullerene containing molecular hydrogen, H₂@C₆₀, is briefly summarized. The synthesis was conducted according to what we call the 'molecular surgical method', that is, opening a hole on a C₆₀ surface, enlargement of the hole, insertion of a guest species and enclosure of the hole without loss of the encapsulated guest. The entire process involves three chemical...

The absorption characteristics of porous absorbers in combination with perforated facings was investigated. The effect of the hole size, hole pattern and open area ratio were examined. The absorption coefficients for an absorber of uniform cross-section were compared to those for an absorber with a tapered cross-section for various volumes of absorbent and different perforated facings.

We review black-hole solutions of higher-dimensional vacuum gravity and higher-dimensional supergravity theories. The discussion of vacuum gravity is pedagogical, with detailed reviews of Myers-Perry solutions, black rings, and solution-generating techniques. We discuss black-hole solutions of maximal supergravity theories, including black holes in anti-de Sitter space. General results and open...
