We walk on two legs, carry around enormous brains and have colonized every corner of the globe. Anthropologists and biologists have long sought to understand how our lineage came to differ so profoundly from the primate norm in these ways, and over the years all manner of hypotheses aimed at explaining each of these oddities have been put forth. But a growing body of evidence indicates that the...

We consider the view data lineage problem in a warehousing environment For a given data item in a materialized warehouse view we want to identify the set of source data items that produced the view item We formalize the problem and we present a lineage tracing algorithm for relational views with aggregation Based on our tracing algorithm we propose a number of schemes for storing auxiliary view...

The concept of ‘community’ has a deep genealogy, extending from the classical social science literature of the nineteenth century to its wide and confused employment in policy contexts and textual analyses discourses. This paper will focus on one aspect of community whose lineage extends theoretically from the communal concept of a ‘consciousness of kind’. In the desert community of Mt Liebig, ...

clusters of coloured balls are three-dimensional models of the developing embryo of the nematode worm, Caenorhabditis elegans. The embryos develop according to a standard pattern, the cell lineage of which was originally worked out by directly observing cells in thousands of embryos under the microscope. But with the advent of 'four-dimensional microscopy', the entire development of one embryo ...

One of the key observations about the distribution of life on Earth is that it is non-random in space and time. Description of these spatio-temporal patterns represents the data of biogeography, and explanation of these spatio-temporal patterns has driven the development of the science of biogeography. Perhaps the concept most associated with the description of distributions is endemism, which ...

Thomas Hanna traced his lineage of somatic education back through two primary teachers: F.M. Alexander (The Alexander Technique) and M. Feldenkrais (Functional Integration). Though he acknowledged other teachers as well (Hanna: 1990), these are the two he cited as most central to his lineage. All of the developments in the field entailed two aspects: sensory awareness and motor (movement) contr...

Objective(s):Sea cucumber derived bioactive compound is considered efficient in treatment of bone disorders. This study was performed   to evaluate the effect of this extract on differentiation of rat bone marrow mesenchymal stem cells (rBMMSc) into osteogenic lineage. Materials and Methods: Isolated rBMMSc were grown in DMEM supplemented with 10% FBS. The cells were exposed to different concen...
