‎there is much interest in finding short presentations for the finite‎ ‎simple groups‎. ‎indeed it has been suggested that all these groups are‎ ‎efficient in a technical sense‎. ‎in previous papers we produced nice‎ ‎efficient presentations for all except one of the simple groups with‎ ‎order less than one million‎. ‎here we show that all simple groups with‎ ‎order between $1$ million and $5$ ...

In this article, we present a new method to study relative Cuntz-Krieger algebras for higher-rank graphs. We only work with edges rather than paths of arbitrary degrees. then use simplify the existing results about algebras. also give applications ideals and quotients Toeplitz

Prior to this paper all small simple groups were known to be efficient but the status of four of their covering groups was unknown. We produce nice efficient presentations for all of these groups, resolving the previously unknown cases. We give presentations that are better than available before in terms of length and in terms of computational properties. In many cases our presentations have mi...

castleman disease (cd) is a rare, lymphoproliferative disorder of uncertain etiology. we are reporting on two cases of castleman disease. both patients were female. this disease can be found wherever lymph nodes are present. we have reported two unusual cases of castleman disease. a 29- year old woman was referred for evaluation because of a cervical lymph node, weight loss and night sweats. th...

If a finite group G has a presentation with d generators and r relations, it is well-known that r−d is at least the rank of the Schur multiplier of G; a presentation is called efficient if equality holds. There is an analogous definition for proficient profinite presentations. We show that many perfect groups have proficient presentations. Moreover, we prove that infinitely many alternating gro...

herein, we present the case of a child with acute lymphoblastic leukaemia who simultaneously developed probable invasive aspergillosis and was diagnosed with gi mucormycosis by histopathologic examination. the patient referred to the pediatric intensive ca re unit of ege university due to clinical deterioration and severe lower gastrointestinal system bleeding. main symptoms were abdominal dist...

This paper describes the technology and methodology used in the development and evaluation of an online network to help the instructors to produce and share video presentations in a new and innovative way. The network offers an application and platform for recording and sharing video presentations. The application allows instructors to narrate and annotate PowerPoint slides and synchronize a va...

ORAL PRESENTATIONS Discussion: Cross-resistance to different antibacterial agents including quinolones and nalidixic acid, chloramphenicol, trimethoprim and in some cases b-lactam antibiotics is a common phenomenon in Gram-negative bacteria (Gutmann et al., 1995). In this study adaptive resistance in Salmonella enterica and E. coli O157, O55 and K-12 was readily achieved by passage in sublethal...
