Beamforming Techniques for Large-N Aperture Arrays

, 2010
Beamforming is central to the processing function of all phased arrays and becomes particularly challenging with a large number of antenna element (e.g. >100,000).

Calibrating Array Detectors [PDF]

, 2000
The development of sensitive large format imaging arrays for the infrared promises to provide revolutionary capabilities for space astronomy. For example, the Infrared Array Camera (IRAC) on SIRTF will use four 256 x 256 arrays to provide background ...

Mapping our Universe in 3D with MITEoR

, 2013
Mapping our universe in 3D by imaging the redshifted 21 cm line from neutral hydrogen has the potential to overtake the cosmic microwave background as our most powerful cosmological probe, because it can map a much larger volume of our Universe, shedding

ORTHOGONAL ARRAYS OBTAINED BY ARRAY SUBTRACTION

Journal of Applied Analysis & Computation, 2021
Summary: In this paper, by using the orthogonal decompositions of projection matrices, a new general approach is proposed to construct asymmetrical OAs, namely array subtraction, the operation of which is not the usual subtraction but it is interesting since many so called atoms of asymmetrical OAs can be obtained by the array subtraction.

Supersymmetric laser arrays [PDF]

Science, 2019
Stability through symmetry A common route to get more light out of a laser system is to couple multiple lasers to form an array. However, instabilities owing to cross-talk and interference between different modes of individual cavities is generally detrimental to performance and could ultimately be damaging to the laser cavities.

SNP Arrays [PDF]

Microarrays, 2016
The papers published in this Special Issue “SNP arrays” (Single Nucleotide Polymorphism Arrays) focus on several perspectives associated with arrays of this type. The range of papers vary from a case report to reviews, thereby targeting wider audiences working in this field. The research focus of SNP arrays is often human cancers but this Issue expands

Predicting the Future Burden of Renal Replacement Therapy in Türkiye Using National Registry Data and Comparative Modeling Approaches

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...
