We study the expansion of stable structures by adding predicates for arbitrary subsets. Generalizing work of Poizat-Bouscaren on the one hand and Baldwin-BenediktCasanovas-Ziegler on the other we provide a sufficient condition (Theorem 4.7) for such an expansion to be stable. This generalization weakens the original definitions in two ways: dealing with arbitrary subsets rather than just submod...

We introduce the concept of orbit-homogeneity of permutation groups: a group G is orbit thomogeneous if two sets of cardinality t lie in the same orbit of G whenever their intersections with each G-orbit have the same cardinality. For transitive groups, this coincides with the usual notion of t-homogeneity. This concept is also compatible with the idea of partition transitivity introduced by Ma...

While much research has investigated the association between personality and health, little research has done so using a bereaved sample. Additionally, little research has investigated how personality influences the frequency of negative social exchanges bereaved individuals receive. This study utilized a structural equation model to investigate the associations among age, gender, personality, ...

Ancient Eastern thought posited the ontological integration of the "mind-body world". The body-mind syncretism was a foundational precept in Eastern philosophy in which "Gih" ("Qi") was considered the basic entity of the universe and the human being. This study attempts to build a meta-theory and to demonstrate empirical designs for Gih, discussing the problems of the mind and body, or the subj...

INTRODUCTION With the advent of high field 3T and ultrahigh field 7T MR systems, significant improvements in a variety of brain imaging modalities were anticipated. Although improvements in SNR have been demonstrated at 3T and 7T [1, 2], limitations due to increased static field (B0) inhomogeneity have also been noted. One modality particularly affected by poor B0 homogeneity is magnetic resona...

Interaction increases flexibility of segmentation but it leads to undesirable behaviour of an algorithm if knowledge being requested is inappropriate. In region growing, this is the case for defining the homogeneity criterion, as its specification depends also on image formation properties that are not known to the user. We developed a region growing algorithm that learns its homogeneity criter...

introduction superficial x-ray therapy is one of the most important treatment methods in radiotherapy especially in the treatment of superficial skin lesions (up to 300 kvp). quality of the x-ray beam that can be expressed by half-value layer (hvl), are important indices for this type of treatment effective energy of photon and homogeneity coefficient (hc). materials and methods the hc of the s...
