In this paper we study the production of pairs of neutral and charged black holes by domain walls, finding classical solutions and calculating their classical actions. We find that neutral black holes whose creation is mediated by Euclidean instantons must be produced mutually at rest with respect to one another, but for charged black holes a new type of instanton is possible in which after for...

A clinical case is presented in which a new type of fiber post was used in combination with the proprietary dual-curing resin cement to bond in a wide, nonrounded root canal. The anatomic post was inserted and the relining resin photopolymerized. The anatomic post was then removed and a luting procedure was performed, as for any other translucent post. The clinical procedure was simple, and a s...

In order to meet the needs of performance-based seismic design, a new type of adaptive-slit shear wall that is easy to construct and behaves well under cyclic loading is introduced to improve the seismic performance of conventional shear wall structures. The seismic damage of an adaptive-slit shear wall develops gradually and it transforms from integral wall into slit wall. The mechanical chara...

This study proposes a new type of calcium phosphate (CaP) scaffolds with a continuously gradient macro/microporous structure using the ceramic/camphene-based 3D extrusion process. Green filaments with a continuously gradient core/shell structure were successfully produced by extruding a bilayered feedrod comprised of a CaP/camphene mixture lower part and a pure camphene upper part. The extruded...

We study the structure of the tenacious (existing for all values of masses of the matter fields) BPS domain walls interpolating between different chirally asymmetric vacua in supersymmetric QCD in the limit of large masses. We show that the wall consists in this case of three layers: two outer layers form a “coat” with the characteristic size ∼ Λ SYM and there is also the core with width ∼ m−1....

We present a new type of brane inflation motivated by multikink solitonic solutions of a scalar field in five dimensions. In the thin brane limit, we analyze a nonstatic configuration in which the distance between two parallel domain walls decreases. We show that the ensuing spacetime is inflationary, both on the branes, and, for certain potentials, in the bulk. We argue that this inflationary ...

We consider domain walls that appear in supersymmetric QCD with Nf , Nc massive flavors. In particular, for 2Nf , Nc we explicitly construct the domain walls that interpolate between vacua labeled by i and i 1 Nf . We show that these solutions are Bogomol’nyi-Prasad-Sommerfield saturated for any value of the mass of the matter fields. This fact allows us to evaluate the large mass limit of thes...

We study a new type of one-dimensional chiral states that can be created in bilayer graphene (BLG) by electrostatic lateral confinement. These states appear on the domain walls separating insulating regions experiencing the opposite gating polarity. While the states are similar to conventional solitonic zero modes, their properties are defined by the unusual chiral BLG quasiparticles, from whic...

This paper proposes a new algorithm, called TAM-WAP(the shorthand for Top-down Algorithm for Mining Web Access Patterns), to mine interesting WAP from Web logs. TAM-WAP searches the P-tree database in the top-down manner to mine WAP. By selectively building intermediate data according to the features of current area to be mined, it can avoid stubbornly building intermediate data for each step o...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...
