Posterior Corneal Astigmatism
… we must take into account that the anterior and posterior surfaces of the cornea have different astigmatic magnitudes and axes. Total astigmatism of the cornea is determined by the combination of both anterior corneal astigmatism and posterior corneal astigmatism. In order to treat astigmatism of …

Mechanical Behavior of Posterior Implant Supported Restorations
This laboratory study was designed to evaluate the fatigue and fracture resistance of different CAD/CAM customized implant-supported restorations using two materials, monolithic zirconia and monolithic lithium disilicate and using two crown designs, hybrid-abutment-crowns and hybrid-abutments with …

Posterior segmental spinal fixation in Scoliosis surgery
Spinal deformity was recognised in the ancient works for philosophy, religion, myths, and fairy tales dating back as far as 3500BC[1,6]. Scoliosis was first described in the 5th century BC by Hippocrates. He recommended treatment with axial distraction on an extension apparatus (figure 1).

Zebrafish Posterior Lateral Line Organogenesis Regulation by Notch Signaling
Organ morphogenesis depends on the precise orchestration of cell migration, cell fate specification and cell shape chages. Results in this thesis demonstrate that Notch signaling is an integral part of the feedback loop between Wnt and Fgf signaling that underlies the self‐organization of …

Fast EM Based Posterior Approximation for IRT Item Parameters
… that has recently become popular for this is posterior predictive model checking (PPMC). This is commonly implemented using the joint posterior distribution of the item parameters as estimated through Markov chain Monte Carlo (MCMC). MCMC estimation is typically very computationally intensive …

Scalable Full Posterior Inference for Uncertainty-Aware Robot Perception
… scalable and expressive approximations for posterior distributions in SLAM, overcoming the limited expressivity of Gaussian approximations for representing commonly encountered non-Gaussian posteriors. We harness the sparsity in factor graphs for scalability and utilize diverse density …

Traditional Posterior Load Carriage: Ergonomic Assessment and Intervention Efficacy
… using a particular MMH method called traditional posterior load carriage (PLC). Such load carriage is typically done without the use of an assistive device (e.g., backpack) in developing countries, and involves exposure to known risk factors for MSS such as heavy loads, non-neutral postures, and …

Fast program for sequence alignment using partition function posterior probabilities
The key requirements of a good sequence alignment tool are high accuracy and fast execution. The existing Probalign program is a highly accurate tool for sequence alignment of both proteins and nucleotides. However, the time for execution is fairly high. The focus is therefore, to reduce the …
