In this paper we present an analysis of the generalized sidelobe canceller (GSC). It can be shown that the theoretical limits of the noise reduction performance depend only on the autoand crossspectral densities of the input signals. Furthermore, we compute the limits of the noise reduction performance for the theoretically determined diffuse noise field, which is an approximation for reverbera...

El objetivo de este artículo es evaluar la visibilidad los investigadores Panamá y el impacto sus publicaciones utilizando indicadores bibliométricos como h-index, i10-index citas perfiles en Google Scholar Citations (GSC) categorizados por sexo, institución, miembro del SNI. Para recolección automática datos GSC se creó un algoritmo lenguaje R que extrajo 860 47 instituciones, 25,5% no contabi...

The mechanisms by which the insulin-sensitive glucose transporter, GLUT4, is targeted and retained in a storage compartment near to the Golgi complex are poorly understood. Here we report that removal of the carboxyl-terminal acidic Pro(505)AspGluAsnAsp(509) sequence prevents the storage of GLUT4 in the VAMP-2 positive compartment adjacent to the Golgi complex (GSC), and results in its targetin...

Modern distributed systems often achieve availability and scalability by providing consistency guarantees about the data they manage weaker than linearizability. We consider a class of such consistency models that, despite this weakening, guarantee that clients eventually agree on a global sequence of operations, while seeing a subsequence of this final sequence at any given point of time. Exam...

The homeobox gene goosecoid (gsc) and the winged-helix gene Hepatic Nuclear Factor-3beta (HNF-3beta) are co-expressed in all three germ layers in the anterior primitive streak and at the rostral end of mouse embryos during gastrulation. In this paper, we have tested the possibility of functional synergism or redundancy between these two genes during embryogenesis by generating double-mutant mic...

Glioblastomas (GBM) are aggressive and therapy-resistant brain tumours, which contain a subpopulation of tumour-propagating glioblastoma stem-like cells (GSC) thought to drive progression and recurrence. Diffuse invasion of the brain parenchyma, including along preexisting blood vessels, is a leading cause of therapeutic resistance, but the mechanisms remain unclear. Here, we show that ephrin-B...

During Drosophila oogenesis, germline stem cell (GSC) identity is maintained largely by preventing the expression of factors that promote differentiation. This is accomplished via the activity of several genes acting either in the GSC or in its niche. The translational repressors Nanos and Pumilio act in GSCs to prevent differentiation, probably by inhibiting the translation of early differenti...

This study examines the connection between the mean ow shape and the acoustic emission of dual-stream jets. The experimental investigation encompassed jets issuing from coaxial, eccentric, and arcuate nozzles, as well as nozzles with de ectors in the secondary stream. The in ection points of the transverse velocity pro le were used to de ne the generalized secondary core (GSC) of the jet. In co...

The germline stem cells (GSCs) of Drosophila melanogaster ovary provide an excellent model system to study the molecular mechanisms of stem cell self-renewal. To reveal novel factors required for Drosophila female GSC maintenance and/or division, we performed a loss-of-function screen in GSCs by using a collection of P-element-induced alleles of essential genes. Mutations in genes of various fu...

Drosophila male germline stem cells (GSCs) divide asymmetrically, balancing self-renewal and differentiation. Although asymmetric stem cell division balances between self-renewal and differentiation, it does not dictate how frequently differentiating cells must be produced. In male GSCs, asymmetric GSC division is achieved by stereotyped positioning of the centrosome with respect to the stem ce...
