Drawing on sociological theories of networks such as those of Granovetter and Burt, the article considers the emergence of new patterns of hierarchy and discrimination within the ITPS, in a context where formal recruitment procedures are often bypassed in favour of network relationships. It also ...

Despite long being considered as “junk”, transposable elements (TEs) are now accepted as catalysts of evolution. One example is Mutator-like elements (MULEs, one type of terminal inverted repeat DNA TEs, or TIR TEs) capturing sequences as Pack-MULEs in
The new ligand hexakis(imidazol-1-ylmethyl)benzene (hkimb, 1) forms a heavily hydrated coordination polymer with CdF2 of composition Cd(hkimb)F2 · 14 H2O. A unique aspect of the structure is that the water assembles itself into two independent and different hydrogen-bonded 2D networks, whic...
The objective lens is air immersion, so no water interface is required, and it has an 8-mm-long working distance, to enable a variety of headplate designs and other instrumentation that needs to be close to the imaged area (e.g., electrode arrays). In addition, the objective can rotate...
1 Blind Separation of Sources One of the most interesting problems to which Artificial Neural Networks is being applied is the blind separation of independent sources from a (linear) mixture of sources [2, 9]. The problem is blind in that we assume no prior information about either the ...
For data-dependent acquisition (DDA) database construction, peptides were separated onto the analytical column with a 90 min gradient (buffer A: 0.1% Formic acid in water; buffer B: 0.1% Formic acid in 80% ACN) at a constant flow rate of 300 nL/min (2%–25% of buffer B in 0–66...
