Varying illuminations, especially the side lighting effects in face images, is one of the major obstacles in face recognition systems. Various methods have been presented for face recognition under different lighting conditions witch require previous knowledge about Light source and shadow area. In this paper, a novel approach based on H-minima transform to image segmentation and illumination n...
© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim 1 wileyonlinelibrary.com Application area of BCP self-assembled thin films is highly restricted by the limited degree of freedom in pattern symmetry, typically including hexagonal close-packed cylinders/spheres and bilateral symmetric lamellae/cylinder arrays. Sparse density modulated nanopatterns and modified pattern symmetries are demanded for...
Diffuse large B-cell lymphoma can selectively and predominantly infiltrate lymph node sinuses this pattern has been recognized as an unusual morphologic variant of entity. Sinusoidal lymphomas with CD30 expression are even more rare.We present a 63-year-old female, who came in chief complaint mass the axillar region for 2 months. The lymphnode ultrasound revealed multiple suspicious lymphadenop...
CD23 and FMC-7 are normal B-cell antigens used during diagnostic immunophenotyping of suspected lymphoproliferative disorders, but the diagnostic usefulness of antigenic expression patterns of simultaneous 2-color staining and flow cytometric analysis has not been reported. We evaluated the FMC-7 and CD23 expression pattern in 201 cases of B-cell lymphoma from tissue biopsy specimens by multipa...
The distribution pattern of Bullacta exarata was studied in different seasons of 2004 at south shore of Hangzhou Bay, China. We found that the distribution pattern of B. exarata was aggregated in each season by Taylor's power regression and Iwao's plot regresses methods (P < 0.001). Based on two-way ANOVA analysis, the results indicated that the densities were significantly affected by the fact...
Transient pattern electroretinograms (PERGs) and visual evoked potentials (VEPs) were recorded with checkerboard pattern reversal and equiluminance stimulus onset-offset, elicited by a high quality moving mirror stimulator. Different sized checkerboard patterns (0.35-4.2 c/deg) were used as stimulus patterns. The wave forms of the equiluminance stimulus onset responses were similar to ERGs evok...
The aim of the present study was to detect polymorphism in Insulin like growth factor-I (IGF-I) gene of beluga (Huso huso) fish using PCR-SSCP technique and also investigation of its association with growth traits (condition factor, body length and weight). A total of 150 specimens of beluga were randomly selected and DNA was isolated from caudal fin using modified salting out method. Then two ...

We examine the similarities and differences between results for powers of sign pattern matrices and for powers of ray pattern matrices. In particular, we investigate what is known about k-potent patterns and powerful patterns in both the irreducible and reducible cases. 1 Signs, Rays, Sign & Ray Patterns Since at least the 1960’s, the qualitative theory of real matrices has been an extremely fr...
in this pepper fe2o3 nanoparticles were synthesized via a fast microwave method. then fe2o3-tio2 nanocomposites were synthesized by a sonochemical-assisted method. the prepared products were characterized by x-ray diffraction pattern, scanning electron microscopy and fourier transform infrared spectroscopy. the photocatalytic behaviour of fe2o3-tio2 nanocomposites was evaluated using the degrad...
