BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2013-008731 DESCRIPTION We report a 20-year-old male patient, with a history of haemophilia presented with a sudden onset of pain in the right gluteal region of 5 days duration. He is afebrile; there is no history of trauma. He developed painful swelling in his right g...

In loving memory of my mother, Batya 1. Introduction In the theory of mapping class groups, " curve complexes " assume a role similar to the one that buildings play in the theory of linear groups. Ivanov, Korkmaz, and Luo showed that the automorphism group of the curve complex for a surface is generally isomorphic to the extended mapping class group of the surface. In this paper, we show that t...

In this paper, we study a flag complex which is naturally associated to the Thurston theory of surface diffeomorphisms for compact connected orientable surfaces with boundary [21]. The various pieces of the Thurston decomposition of a surface diffeomorphism, thick domains and annular or thin domains, fit into this flag complex, which we call the complex of domains. The main result of this paper...

Aim: The aim of this in vitro study is to describe a preclinical investigation using laser-activated bleaching agent for discolored teeth. Materials and methods: Sixty sound human central and lateral incisors were selected for this study and were randomly assigned into four groups as follows: Group 1 (n=15): only Whiteness HP 10 min; Group 2 (n=15): diode laser, wavelength 980 nm power 0.8 W–30...

Objective: To investigate whether or not patients with subclinical hypothyroidism (SH) have increased epicardial adipose tissue (EAT). Subjects and Methods: Sixty-one patients with newly diagnosed SH and without any known cardiovascular disease were enrolled. Twenty-four subjects matched for age, gender and body mass index without any thyroid dysfunctions were included as a control group. The E...

Bilginin teknoloji ile yaygınlaşması sonucu toplumlar, bilimsel araştırmalarda öncü olmak ve diğerlerinin gerisinde kalmamak için çaba harcamaktadırlar. Özellikle içinde bulunduğumuz çağın sorunlarına daha güvenilir çözümler üretmek amacıyla birçok alanda araştırmalar yapılmaktadır. Bu nedenle bilim insanları çalışmalara yönelik tutumların, olumlu geliştirilebilir düzeyde olması büyük önem taşı...

This paper presents a new approach to automatic word categorization which improves both the eeciency of the algorithm and the quality of the formed clusters. The unigram and the bigram statistics of a corpus of about two million words are used with an eecient distance function to measure the similarities of words, and a greedy algorithm to put the words into clusters. The notions of fuzzy clust...

Literacy practitioners, educators, and researchers have eagerly adopted social media technology, particularly what is referred to as New Literacies (Coiro, Knobel, Lankshear, & Leu, 2007a), as a way to support peertopeer learning, build community, and expand opportunities for expression (Kimmons, 2014). Social media technologies have evolved to the point that they have become common ways of com...
