Optimal antenna configurations for the BIMA Array [PDF]
International Astronomical Union Colloquium, 1991 AbstractWe attempt to determine optimal configurations of six antennas for the proposed Berkeley Illinois Maryland Array. The instrumental response is used as a performance measure. A two dimensional sine function is chosen as the ideal beam, supported by theoretical considerations.

Optimization of array configuration [PDF]
The Journal of the Acoustical Society of America, 1987 The purpose of this study was to determine the optimal configuration of 2-, 3-, and 4- element hydrophone arrays. The noise field was taken to be isotropic and the arrays were constrained to lie in a horizontal plane. It was determined that the optimal configuration is a linear array though, as is the case of the 4-element array, not necessarily ...

L-Shaped Sparse Array Structure for 2-D DOA Estimation
IEEE Access, 2020 In order to improve the performance of two-dimensional (2-D) direction-of-arrival (DOA) estimation, an L-shaped sparse array structured by two new sparse linear arrays is proposed. Each part of the proposed L-shaped array is used for one-dimensional (1-D)

Energy Reports, 2020 In this paper, the effect of Partial Shading Condition (PSC) on various solar photovoltaic (PV) array topologies has been studied extensively. PSC reduces the maximum power of a PV array and produces multiple Maximum Power Points (MPPs) in the PV ...

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Minimal Energy Configurations of Finite Molecular Arrays [PDF]
Symmetry, 2019 In this paper, we consider the problem of characterizing the minimum energy configurations of a finite system of particles interacting between them due to attractive or repulsive forces given by a certain intermolecular potential. We limit ourselves to the cases of three particles arranged in a triangular array and that of four particles in a ...

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
