Regional homogeneity changes in patients with primary insomnia

European Radiology, 2015
The study aimed to explore the regional spontaneous activity changes in primary insomnia (PI) patients.Based on the resting-state fMRI datasets acquired from 59 PI patients and 47 healthy controls, a two-sample t-test was performed on individual normalized regional homogeneity (ReHo) maps.

Growth and homogeneity region of CdTe

Journal of Crystal Growth, 1996
Abstract The works concerning the data regarding solid-phase transformations in cadmium telluride are considered. On the basis of these works the region of CdTe homogeneity has been plotted. The region is characterized by Cd and Te solubility in the range of 1019–1020 cm−3 as well as availability of two-phase fields in the temperature range of solid ...

Homogeneously staining chromosomal region in a case of erythroleukaemia

Scandinavian Journal of Haematology, 1986
Cytogenetical analysis of bone marrow and peripheral blood cells in a case of erythroleukaemia revealed a complex karyotype with a stemline of 44 chromosomes. I marker chromosome bearing a homogeneously staining region (hsr) was found in each of the aneuploid cells examined. The hsr was localised to the chromosome regions 15q12 and 15p12.

A case of erythroleukaemia with homogeneously staining regions on chromosomes

Leukemia Research, 1983
A case of erythroleukaemia with homogeneously staining regions on chromosomes is described. The number of chromosomes in bone marrow cells varied from 41 to 46 with a mode of 43. A variety of structural and numerical chromosomal abnormalities was observed.

Homogeneous regions on the conformal sphere

Mathematical Notes of the Academy of Sciences of the USSR, 1970
All regions on a sphere which are similar with respect to a group of conformal transformations of this sphere are determined. Such regions are: the whole sphere, a hemisphere, the complement of a sphere of lower dimension, and the complement of a point.

Segmentation of Distinct Homogeneous Color Regions in Images

2007
In this paper, we present a novel algorithm to detect homogeneous color regions in images. We show its performance by applying it to skin detection. In contrast to previously presented methods, we use only a rough skin direction vector instead of a static skin model as a priori knowledge.

Deformable boundary finding influenced by region homogeneity

Proceedings of IEEE Conference on Computer Vision and Pattern Recognition CVPR-94, 1994
Accurately segmenting and quantifying structures is a key issue in biomedical image analysis. The two conventional methods of image segmentation, region-based segmentation and boundary finding, often suffer from a variety of limitations. We propose a method which endeavors to integrate the two approaches in an effort to form a unified approach that is ...

Real-time maximally stable homogeneous regions

Journal of Real-Time Image Processing, 2020
In this paper, we present the concept of maximally stable homogeneous regions (MSHR). MSHR are conceptually very similar to maximally stable extremal regions but can be segmented in images with an arbitrary number of channels. The computation of the presented MSHR relies on the construction of a quasi-flat zone hierarchy.

Homogeneously staining regions on marker chromosomes in malignancy

International Journal of Cancer, 1979
AbstractDirect chromosome analysis with G‐banding revealed homogeneously staining regions (HSR) in five of 16 human solid malignant tumours of different histological types. The HSRs were localized either terminally or interstitially on the marker chromosomes.

Behavior of the homogeneous symmetric polynomial in an angular region

Lithuanian Mathematical Journal, 1995
Assume that \(z_0\), \(z_1, \dots, z_n\) belong to an angular region bounded by two rays emanating from the origin, \(\sigma_k (z_0, \dots, z_n) = \sum z_0^{j_0} z_1^{j_1}, \dots, z_n^{j_n}\), \(j_0+j_1 + \cdots + j_n =k\), \(j_s\), \(s=0,1, \dots,n\) being nonnegative integers, stands for a symmetric polynomial, \[ \sigma_k (z,z_1, \dots, z_n) = \sum ...
