Central areolar choroidal dystrophy (CACD) is a retinal disease which causes progressive profound loss of vision in patients during middle age. The disease is inherited as an autosomal dominant trait and shows genetic heterogeneity. Mutations in the peripherin-RDS gene on chromosome 6 have been reported in affected members of families transmitting the disease. A new locus at chromosome 17p13 wa...

Ultrasonic sensors enable mobile autonomous systems to obtain information about obstacles in large environments. In the presented work, taking the limited energy resources of a mobile robot into account, only one transmitter is used. The employment of two receivers permits the calculation of the distance and direction of objects. Using pseudo-random sequences, simultaneously transmitting and re...

Williams-Beuren syndrome is a well-known microdeletion syndrome with a recognizable clinical phenotype. The subtle phenotype of the reciprocal microduplication of the Williams-Beuren critical region has been described recently. We report seven further patients, and a transmitting parent, with 7q11.23 microduplication. All our patients had speech delay, autistic features and facial dysmorphism c...

INTRODUCTION This paper reports, for the first time, the presence of Rhodnius montenegrensis in the State of Acre, Brazil. METHODS Two female R. montenegrensis were collected in a dwelling in the rural area of Rio Branco, Acre, Brazil. RESULTS The occurrence of this species was confirmed, and the number of Triatominae species in the State of Acre increased from four to five. CONCLUSIONS F...

In this paper, the critical transmitting range for connectivity in wireless ad hoc networks is analyzed. More specifically, we consider the following problem: Assume n nodes, each capable of communicating with nodes within a radius of r. The nods are randomly and uniformly distributed in a d-dimensional region with a side of lengthl. In this paper the critical transmission range in dense and sp...

Multiple outbreaks beyond West Africa have been described. Since 2004, chikungunya has spread broadly, causing massive outbreaks with explosive onset in the Indian Ocean region, India, and other parts of Asia [1-3]. Chikungunya had traditionally been perceived as a tropical disease until an outbreak in Italy in 2007. In addition, thousands of cases have been identified in travelers returning fr...

Over the last two decades, three countries in Black Sea Region—Russia, Ukraine, and Kazakhstan—became global leaders grain production trade, replaced USA France as most previous largest wheat exporting countries. In this study we investigate world price linkages identify current “price leaders” of market. This empirical analysis is focused on relationships between eight uses a cointegration fra...
