9 ABSTRACT: Aiming at long registration time and mismatch problems resulted by images that exist local region similar or generated SIFT vector similar in the traditional SIFT registration method, a fine registration method based on geometric constraints of block and parallel architecture is put forward. This method using SIFT algorithm parallelly extract feature points to calculate initial tran...

The photothermal deflection technique is used to measure the thermal diffusivity of a metal+eramic composite. The present, as well as other data on composites are analyzed to estimate a value for the Kapitza radius, rk, which represents the effectivevalue of the thermal boundary resistance of heterointerfaces. Remarkably, the data from different metal+eramic composite materials lead to a simila...

A rate adaptation buuer is used in communications networks at the interface between two consecutive links, when the speed of the incoming link exceeds the speed of the outgoing link, in order to avoid excessive cell loss. In this paper we examine the performance of such a buuer in the case that the ratio between the input rate and the output rate takes an integer value, as well as in the more g...

The MR perfusion diffusion (PI/DWI) mismatch concept for the selection of patients for intravenous thrombolysis (IVT) was introduced with several smaller case series in the late 1990s and early 2000s,1 followed by larger series by many international groups over the last 8 years. A potentially salvageable penumbra was operationally defined as a PI/ DWI-(volume) mismatch where PI indicates the hy...

We present experimental results on the critical exponent QE&E describing the divergence of the Kerr constant of binary liquid mixtures near the critical consolute point. We show that the measured value of its„E agrees with the theoretical prediction only if the measurement is performed with a mixture of two liquids presenting a small mismatch in the dielectric constant, and that the measured Ps...

3D object recognition under partial object viewing is a difficult pattern recognition task. In this paper, we introduce a neural-network solution that is robust to partial viewing of objects and noise corruption. This method directly utilizes the acquired 3D data and requires no feature extraction. The object is first parametrically represented by a continuous distance transform neural network ...

While transmitting the data over communication channel, various problems such as communication error and mismatch arises. For reducing those errors, frequency selective I/Q imbalance using Direct Conversion transmitters can be implemented. I/Q imbalance compensation procedure has been derived and incoherent measurements are required for avoiding the need for time, frequency and phase synchroniz...

Mutational processes underlie cancer initiation and progression. Signatures of these processes in cancer genomes may explain cancer etiology and could hold diagnostic and prognostic value. We developed a strategy that can be used to explore the origin of cancer-associated mutational signatures. We used CRISPR-Cas9 technology to delete key DNA repair genes in human colon organoids, followed by d...

OBJECTIVES The outcome of patients with primary melanoma (PM) cannot be completely explained based on currently adopted clinical-histopathologic criteria. In this study, we evaluated the potential prognostic value of mismatch repair protein expression in PMs. METHODS We examined the immunohistochemical staining of mismatch repair proteins in 18 benign nevi and 101 stage I to III PMs and inves...

A quantitative genetic assay was developed to monitor alterations in tract lengths of trinucleotide repeat sequences in Saccharomyces cerevisiae. Insertion of (CAG)50 or (CTG)50 repeats into a promoter that drives expression of the reporter gene ADE8 results in loss of expression and white colony color. Contractions within the trinucleotide sequences to repeat lengths of 8 to 38 restore functio...
