Migrants from rural Mexico usually move abroad with the idea to return once they have improved their economic situation. Although they do not always go back, Mexican migrants often plan their return before leaving. In any case, the imagined return persists for a long time in their minds. This paper analyzes the ways in which rural migrants from southern Veracruz and western Mexico imagine a bet...

Nowadays, steel shear walls are used as efficient lateral-load-resistant systems due to their high lateral stiffness and carrying capacity. In this paper, the effect of substituting a shape memory alloy (SMA) material is investigated instead of using conventional steel in the shear wall. A numerical study is conducted using finite element method (FEM) by OpenSees software. For this purpose, at ...

Cilt, tezhip ve ebrû gibi İslam sanatları, hat sanatının merkezî rolüyle gelişmiştir. Hat teşhiri başlangıçta Kur’an-ı Kerim’in istinsahı yapılar üzerindeki kitabelerle olmuştur. medeniyeti, farklı milletlerle coğrafyalarda temsil edilmiş ancak hepsinin ortak sanatı her zaman Orta Çağda net bir şekilde kaideleri kuralları olan tek sanatın olduğu bilinmektedir. tarihin hiçbir döneminde belirli z...

Efficient mode shape extraction of fluid-structure systems is of particular interest in engineering. An efficient modified version of unsymmetric Lanczos method is proposed in this paper. The original unsymmetric Lanczos method was applied to general form of unsymmetric matrices, while the proposed method is developed particularly for the fluid-structure matrices. The method provides us with si...

In this note, we give an explicit polynomial-time executable strategy for Peter Winkler’s hat guessing game that gives superior results if the distribution of hats is imbalanced. While Winkler’s strategy guarantees in any case that ⌊n/2⌋ of the n player guess their hat color correct, our strategy ensures that the players produce max{r, b} − 1.2n2/3 − 2 correct guesses for any distribution of r ...

The essential requirement for polyamines for normal cell growth and differentiation may be partly attributed to their influence on gene expression, a process regulated by the acetylation state of nucleosomal histones. We used transgenic mice to examine the effects of constitutive expression of ornithine decarboxylase (ODC), a key rate-limiting enzyme in polyamine biosynthesis, on histone acetyl...

A new hexaazatriphenylene (HAT) derivative formed by the fusion of three HAT units has been prepared and its electronic and molecular structures have been fully characterized by optical and vibrational Raman spectroscopy, electrochemistry, solid-state UV and inverse photoemission spectroscopy (UPS and IPES), and by quantum-chemical calculations. A comparative HAT versus tri-HAT study was perfor...

Tries are the fastest tree-based data structures for managing strings in-memory, but are space-intensive. The burst-trie is almost as fast but reduces space by collapsing trie-chains into buckets. This is not however, a cache-conscious approach and can lead to poor performance on current processors. In this paper, we introduce the HAT-trie, a cache-conscious trie-based data structure that is fo...

Membrane-bound proteases are essential for epidermal integrity. Human airway trypsin-like protease 4 (HAT-L4) is a type II transmembrane serine protease. Currently, its biochemical property, cellular distribution and physiological function remain unknown. Here we examined HAT-L4 expression and function in vitro and in vivo. In Western analysis, HAT-L4 expressed in transfected CHO cells appeared...

Human airway trypsin-like protease (HAT) was isolated from airway secretions and localized to bronchial epithelial cells by immunohistochemistry. In the present study, we examined whether HAT could stimulate DNA synthesis and proliferation of primary human bronchial fibroblasts (HBF). HAT significantly stimulated the proliferation of HBF by 20-55%, a level similar to that of the mitogenic activ...
