A separator in a graph \(G\) is a partition \((A,B,C)\) of \(V(G)\) such that \(| A|\), \(| B|\leq {2\over 3}| V(G)|\) and no vertex in \(A\) is adjacent to any vertex in \(B\); its order is \(| C|\). The authors give a short proof of a theorem of Lipton and Tarjan that for any planar graph with \(n\) vertices there is a separator of order \(\leq 2 ...

Dielectrophoretic separation of cells: Continuous separation
Biotechnology and Bioengineering, 1995AbstractDielectrophoresis is the movement of particles in non‐uniform alternating and direct current (AC, DC) electric fields. When nonuniform electric fields are created between microelectrodes, cells will redistribute themselves around the electrodes, the force holding the cells in place dependig on the local electric field and on the electrical ...

The separation of adult separation anxiety disorder
CNS Spectrums, 2016The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) categorization of mental disorders places “separation anxiety disorder” within the broad group of anxiety disorders, and its diagnosis no longer rests on establishing an onset during childhood or adolescence.

A separability parameter for dielectrophoretic cell separation
ELECTROPHORESIS, 2013In this study, a separability parameter is introduced to determine the selection of optimum operating parameters for DEP separation of a cell pair. The separability parameter is defined as a function of cells’ Clausius–Mossotti (CM) factors. T‐cell leukemia Jurkat and mouse melanoma B16 cells are tested to validate the separability parameter.

ESDI: “Separable but not separate”?
Air & Space Europe, 2000The development of a European Security and Defence Identity that is “separable but not separate” from NATO took a new turn at the European Union's Helsinki summit in December 1999, However, the EU's plans to absorb soon the Western European Union and to create a rapid reaction corps by 2003 raise a tangle of membership issues, as well as questions of a

Phase separation, charge separation and biogenesis
Biosystems, 1981The current view of bioenergetics postulates transmembrane charge separation as a primary mechanism of energy storage and transformation. Using that bioenergetic view we examine possible methods of photon driven transduction in primordial vesicles.
