In [2] it was conjectured that all integer sequences (ak)k∈Z satisfying 0 ≤ ak−1 + λak + ak+1 < 1 (k ∈ Z) for real λ with |λ| < 2 are periodic. This question arose in the study of shift radix systems. The conjecture is trivially true for λ = −1, 0, 1. A computer assisted proof for λ = 1− √ 5 2 was given by Lowenstein, Hatjispyros and Vivaldi [5], where also the solution for λ = 1+ √ 5 2 is ment...

OBJECTIVE To evaluate the performance of GeneXpert for detection of mycobacterium tuberculosis in pus samples and compare its results with conventional techniques in terms of validity, rapidity and rifampicin resistance. METHODS This longitudinal, descriptive study was conducted at Jinnah Hospital, Lahore, Pakistan, from January 2012 to December 2015, and comprised pus samples of people suspe...

Giant condyloma acuminatum or Buschke-Lowenstein tumour is a very rare disease which usually is located in the genital, anorectal, and perianal regions. It is regarded as a type of verrucous carcinoma occurring on anogenital mucosal surfaces where it is locally invasive but displays a benign cytology. We describe a case of a 24-year-old woman with persisting condyloma acuminata progressing to a...

Around 50 mycobacteria species cause human disease. Immunosuppressive states predispose to non-tuberculous mycobaterium infection, such as Mycobacterium chelonae: AFB, non-tuberculous, fast growth of low virulence and uncommon as a human pathogen. It may compromise the skin and soft tissues, lungs, lymph nodes and there is also a disseminated presentation. The diagnosis involves AFB identificat...

Os autores fazem o relato de três casos clínicos: Papilomatose florida, Epitelioma cuniculatum e Condiloma gigante Buschke Lowenstein, considerados como representativos entidades que compõem grupo das Papilomatoses pseudo-carcinomatosas. São favoráveis à conceituação pseudo-carcinomatosas apoiando-se na semelhança clínica, histopatológica, evolutiva da terapêutica a ser instituída. Discutem, ai...

We reexamine the effects of the anchoring manipulation of Ariely, Lowenstein and Prelec (2003) on the valuation of common market goods and found very weak anchoring effects. We perform the same manipulation on the evaluation of binary lotteries, and find no anchoring effects at all. This suggests limits on the robustness of anchoring effects. § We thank Drazen Prelec for many helpful conversati...

153 This volume of a seemingly endless series consists of two reviews which were omitted from two earlier volumes. The first review is authored by J. M. Lowenstein and concerns the pyruvate dehydrogenase complex and the citric acid cycle. This review suffers from a restricted scope and a change in emphasis midway through the manuscript. Although the title of the volume promises a discussion of ...
