We study charge ordering driven by Coulomb interactions on triangular lattices relevant to the Wigner-Mott transition in two dimensions. Dynamical mean-field theory reveals the pinball liquid phase, a charge ordered metallic phase containing quasilocalized (pins) coexisting with itinerant (balls) electrons. Based on an effective periodic Anderson model for this phase, we find an antiferromagnet...

Clustering protein-protein interaction networks (PINs) helps to identify complexes that guide the cell machinery. Clustering algorithms often create a flat clustering, without considering the layered structure of PINs. We propose the MULIC clustering algorithm that produces layered clusters. We applied MULIC to five PINs. Clusters correlate with known MIPS protein complexes. For example, a clus...

Die Bilder zeigen ICs aus dem Praktikum. Aus einem Kunststoffgehäuse führen 14 Beine heraus, die Pins genannt werden. Am Kunststoffgehäuse ist eine Kerbe angebracht, die die Orientierung des ICs festlegt. (Der Aufdruck ist nicht maßgeblich für die Orientierung, nur die Kerbe!) Wenn man nun von oben auf das IC schaut, also die Pins nach unten zeigen und die Kerbe links ist, dann ist links unten ...

Ef®cient indexing on a class hierarchy is essential for the achievement of high performance in query evaluation for object databases. In this paper, we present a practical indexing scheme, Partition Index Con®guration Scheme (PINS), which provides good index con®gurations for any real database environment. PINS considers the distribution of key values, as well as query patterns such as query fr...

A new belt transmission mechanism, having the function of no-slip driving, is described in the paper. It is composed of pulleys with carved rails and belt with rolled pins spaced out on both sides. Firstly, the trajectory curve is deduced along which pins embedded in the pulley. And then, parametric relationships are established, which are about center offsets of two pulleys, working radius of ...

The popular mythology surrounding the U.S. venture-capital industry derives from a previous era. Venture capitalists who nurtured the computer industry in its infancy were legendary both for their risk taking and for their hands-on operating experience. But today things are different, and separating the myths from the realities is crucial to understanding this important piece of the U.S. econom...

OBJECTIVE To compare the locked, unreamed intramedullary nail with Ender pins in the treatment of open Gustilo grade I or II or closed tibial diaphyseal fractures of type A, B, or C2 of the AO classification. MATERIALS AND METHODS Forty-four patients with unilateral tibial diaphyseal fractures were treated with intramedullary nails or Ender pins. Twenty patients were treated with an unreamed ...

MOTIVATION Proteins underlay the functioning of a cell and the wiring of proteins in protein-protein interaction network (PIN) relates to their biological functions. Proteins with similar wiring in the PIN (topology around them) have been shown to have similar functions. This property has been successfully exploited for predicting protein functions. Topological similarity is also used to guide ...

OBJECTIVES Osteochondral injuries, if not treated adequately, often lead to severe osteoarthritis. Possible treatment options include refixation of the fragment or replacement therapies such as Pridie drilling, microfracture or osteochondral grafts, all of which have certain disadvantages. Only refixation of the fragment can produce a smooth and resilient joint surface. The aim of this study wa...

An assay technique, homogeneous enzyme immunoassay, is described for the quantitative determination of morphine derivatives in biological fluids. An enzyme is labeled with morphine. When the enzymelabeled morphine is bound by antimorphine antibodies, the enzyme is rendered inactive. Free morphine competes with enzyme-morphine for antibody binding sites preventing inhibition of enzyme activity. ...
