Bell Laboratories Layer Space-Time (BLAST) is a transceiver architecture for offering spatial multiplexing over multiple-antenna wireless communication systems. Such systems have multiple antennas at both the transmitter and the receiver in an effort to exploit the many different paths between the two in a highly- scattering wireless environment.
In cell biology, precursor cells—also called blast cells—are partially differentiated, or intermediate, and are sometimes referred to as progenitor cells. A precursor cell is a stem cell with the capacity to differentiate into only one cell type, meaning they are unipotent stem cells .
A comprehensive diagram of human hematopoiesis. Granulopoiesis consists of 5 stages, in which the myeloblast is the first recognizable cell. Next in the differentiation sequence is the monoblast and the promyelocyte, which can develop into one of three different precursor cells: the neutrophilic, basophilic or eosinophilic myelocyte.
A proerythroblast (or rubriblast, or pronormoblast) is a precursor cell to the normoblast (nucleated red blood cell), as the earliest of four stages in its development.. In histology, it is very difficult to distinguish it from the other "-blast" cells (lymphoblast, myeloblast, monoblast, and megakaryoblast).
The Chronic Lymphocytic Leukemia Research Consortium defines a lymphoblast as "A lymphocyte that has become larger after being stimulated by an antigen. Lymphoblasts look like immature lymphocytes, and were once thought to be precursor cells." [4] Commonly, when speaking about leukemia, "blast" is used as an abbreviation for lymphoblasts.
Earth has been hit by a blast from a dead star so energetic that scientists cannot explain it. The burst of gamma rays, originating in a dead star known as a pulsar, is the most high energy of its ...
Currently, there is a tendency to call both forms fibroblasts. The suffix "-blast" is used in cellular biology to denote a stem cell or a cell in an activated state of metabolism. Fibroblasts are morphologically heterogeneous with diverse appearances depending on their location and activity.
An ongoing Geomagnetic Storm Warning was extended through Tuesday after a blast of energetic particles from the Sun reached Earth.. NOAA's Space Weather Prediction Center (SWPC) issued a ...
