We explore the numerical reconstruction of the potential energy profile of a molecular bond from distributions of bond rupture times. For a single measured first passage time (FPT) distribution the inverse problem is highly ill-conditioned and only a few attributes (such as the height and width of an energy barrier) can usually be reconstructed. Upon more careful analysis, we find optimal tempe...

Comparison of atom probe tomography (APT) results from different instruments, different users, or different samples requires confidence in overall reconstruction accuracy. The conventional reconstruction algorithm utilizes a single point-projection onto a spherical surface [1,2]. Although there are a limited number of parameters used to prescribe how detector events are converted to a 3D set of...

background: the technique most frequently employed for breast reconstruction, either immediate (ibr) or delayed (dbr), is the insertion of a prosthesis. the placement of a foreign body always carries the risk, albeit small, of peri-prosthetic infection and exposure of the implant that necessitates its removal, signaling the temporary or permanent failure of the reconstruction. methods: we retro...

injuries to the posterolateral corner (plc) comprise a significant portion of knee ligament injuries. a high index of suspicion is necessary when evaluating the injured knee to detect these sometimes occult injuries. moreover, a thorough physical examination and a comprehensive review of radiographic studies are necessary to identify these injuries. in this sense, stress radiographs can help to...

PURPOSE To develop a novel approach for calculating the accurate sensitivity profiles of phased-array coils, resulting in correction of nonuniform intensity in parallel MRI. MATERIALS AND METHODS The proposed intensity-correction method estimates the accurate sensitivity profile of each channel of the phased-array coil. The sensitivity profile is estimated by fitting a nonlinear curve to ever...

Registration of DWI data, unlike scalar image data, is complicated by the need of reorientation algorithms for keeping the orientation architecture of each voxel aligned with the rest of the image. This paper presents an algorithm for effective and efficient warping and reconstruction of diffusion-weighted imaging (DWI) signals for the purpose of spatial transformation. The key idea is to decom...

We present a study of rough surface inverse scattering problems using evolutionary strategies. The input data consists of far-field angle-resolved scattered intensity data, and the objective is to reconstruct the surface profile function that produced the data. To simplify the problem, the random surface is assumed to be one-dimensional and perfectly conducting. The optimum of the fitness funct...

The archivation process of ancient pottery is a very time consuming but important task for archaeologists. The basis for classification and reconstruction is the profile which is the cross section of the fragment in the direction of the rotational axis. In this work a bottom up design using a description language is the basis for the automatic classification and reconstruction. The description ...

An automated algorithm is presented to determine the DNA molecule intrinsic curvature profiles and the molecular spatial orientations in Atomic Force Microscope images. The curvature is composed by static and dynamic contributions. The first one is the intrinsic curvature, vectorial function of the DNA nucletide sequence, while the second one is due to thermal noise. This algorithm allows to re...
