... point out that in hornets the abdomen is called a gaster, because the first segment of the abdomen conjoins during the pupal stage with the three segments of the tho- rax and it is the remaining ... image of the tissue. The magnetic spins are excited in slices of finite width, and for each slice, a single image is obtained. The relative intensity of each elem...

... [14,20]. Binding of CCE1 results in the complete unpairing of the four base-pairs in the centre of the junctions with a lesser disruption of the next base-pairs [19], which is reminiscent of the structure ... base-pairs in the centre of the junctions [19]. Detailed understanding of the functional role of these interactions would require the crystal st...
