background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...

We present a system for creating and manipulating layered procedural surface editing operations, which is motivated by the limited support for iterative design in free-form modeling. A combination of sketch-based and traditional modeling tools are used to design soft displacements, sharp creases, extrusions along 3D paths, and topological holes and handles. Using local parameterizations, these ...

Free N = 4 Super Yang-Mills theory (in the large N limit) is dual to an, as yet, intractable closed string theory on AdS5 × S. We aim to implement open-closed string duality in this system and thereby recast the free field correlation functions as amplitudes in AdS. The basic strategy is to implement this duality directly on planar field theory correlation functions in the worldline (or first q...

We present an approach for inferring symbolic resource bounds for purely functional programs consisting of recursive functions, algebraic data types and nonlinear arithmetic operations. In our approach, the developer specifies the desired shape of the bound as a program expression containing numerical holes which we refer to as templates. For e.g, time ≤ a ∗ height(tree) + b where a, b are unkn...

Large-scale N-body simulations play an important role in advancing our understanding of the formation and evolution of large structures in the universe. These computations require a large number of particles, in the order of 10-100 of billions, to realistically model phenomena such as the formation of galaxies. Among these particles, black holes play a dominant role on the formation of these st...

The potential use of expanded polystyrene (EPS) beads for control of Aedes triseriatus was tested in the laboratory and the field. Laboratory studies showed that beads present in amounts which persisted throughout a season significantly reduced the emergence of Ae. triseriatus adults by preventing normal eclosion from the pupae. In the field, tree holes containing EPS beads had significantly fe...

Dedicated to that mysterious Power: Who requires odd holes for imperfection in graphs And ensures unimodularity of network flows Who converges large numbers towards normality And lets greediness work for the spanning tree Who animates the intelligence inside us And creates the world-illusion around us She is the seed of all creativity And without Her grace This work would forever remain a mere ...

We discuss a model for the early assembly of supermassive black holes (SMBHs) at the center of galaxies that trace their hierarchical build-up far up in the dark halo ‘merger tree’. Motivated by the observations of luminous quasars around redshift z ≈ 6 with SMBH masses ≈ 10M⊙, we assess the possibility of an early phase of stable super-critical quasi-spherical accretion in the BHs hosted by me...
