Deformable geometric models can be used in the context of Bayesian analysis to solve ill-posed tomographic reconstruction problems. The uncertainties associated with a Bayesian analysis may be assessed by generating a set of random samples from the posterior, which may be accomplished using a Markov-Chain Monte-Carlo (MCMC) technique. We demonstrate the combination of these techniques for a rec...

A diverse array of molecular markers and constantly evolving analytical approaches have been employed to reconstruct the invasion histories of the most notorious invasions. Detailed information on the source(s) of introduction, invasion route, type of vectors, number of independent introductions and pathways of secondary spread has been corroborated for a large number of biological invasions. I...

Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract The Optimal Ranking Regime (ORR) method was used to identify 6–100 year time windows containing significant ranking sequences in 55 western US streamflow reconstructions , and reconstructions of the level of the Great S...

In-situ scanning tunneling microscopy studies have been performed on the GaN(000 ) surface. Four dominant reconstructions have been observed: 1×1, 3×3, 6×6, and c(6×12). The 1×1 structure is formed by annealing the as-grown GaN surface to desorb excess Ga atoms. The higher order reconstructions are formed by depositing sub-monolayer quantities of Ga atoms onto this 1×1 surface. STM images showi...

We derive equilibrated reconstructions of the Darcy velocity and of the total stress tensor for Biot’s poro-elasticity problem. Both reconstructions are obtained from mixed finite element solutions of local Neumann problems posed over patches of elements around mesh vertices. The Darcy velocity is reconstructed using Raviart–Thomas finite elements and the stress tensor using Arnold–Winther fini...

of the auditory ossicles in chronic otitis media patients. Materials and Methods: This study was carried out in 30 ears with chronic otitis media. All cases underwent an axial multidetector computed tomography imaging study. In addition to the axial images, sagittal and coronal multiplanar two-dimensional reformations and three-dimensional reconstructions were generated. Auditory ossicles were ...

This paper presents a new technique for estimating a multiview reconstruction given pair-wise Euclidean reconstructions up to rotations, translations and scales. The partial reconstructions are glued by the following three step procedure: (i) Camera rotations consistent with all reconstructions are estimated linearly. (ii) All the pair-wise reconstructions are modified according to the new rota...

Reconstructions of the AlN(0001) surface are studied. For moderately Al-rich surfaces, surface reconstructions with symmetry of o 30 3 2 3 2 R − × and o 30 3 5 3 5 R − × are found on the basis of scanning tunneling microscopy and lowenergy electron diffraction observations. Such surfaces display a predominantly 2 × 6 pattern in reflection high-energy electron diffraction. Auger electron spectro...

The reconstructions of the InP~001! surface prepared by molecular beam epitaxy have been studied with in situ reflection high-energy electron diffraction ~RHEED! and scanning tunneling microscopy ~STM!. The growth chamber contains a highly accurate temperature measurement system and uses a solid-source, cracked phosphorus, valved effusion cell. Five InP~001! reconstructions are observed with RH...

BACKGROUND Although immediate breast reconstruction with the insertion of a permanent prosthesis rather than a tissue expander (direct to implant [DTI]) has become gradually more preferred and requested by patients, the technique has yet to be fully embraced by most plastic surgeons, presumably due to concerns of patient safety and perceived higher complication and revision rates, despite not b...
