In experiments where DNA is pulled at constant force and twisted, a mixedstate of extended twisted DNA and plectonemically supercoiled DNA iseasily obtained. I will review the thermodynamics of this 'statecoexistence' phenomenon. A particularly elegant use ofplectoneme-extended DNA coexistence is as a source of constant torque forsingle-DNA expe...

Scale. Scale mechanism is encased in a box made from a wooden frame and beveled glass walls; scale mechanism is an equal arm, torsion balance made of metal with torsion springs attached to both weighing arms and the central column; two round metal pans with rectangular, curved handles are supported by the outer two weighing arms emerging from th...

In this talk, I will introduce two algorithms for image segmentation and graph clustering. One of the most influential image segmentation models is the Mumford-Shah's model. Several algorithms such as the level set method have been introduced to compute a minimizing solution to the MS's problem, but none of them can compute a global solution. We...
