We show that the π-equivariant chain complex (π = π1(M(A))), C•(X̃), associated to a Morse-theoretic minimal CW -structure X on the complement M(A) of an arrangement A, is independent of X . The same holds for all scalar extensions, C•(X̃)⊗Zπ KZ, K a field, where X is an arbitrary minimal CW -structure on a space M . When A is a section of another arrangement Â, we show that the divisibility prop...

The convergence of social networking andmobile computing is expected to generate a new class of applications, called Mobile Social Networking (MSN) applications, that will be of significant importance for the coming years. Indeed,MSN enhances the capabilities ofmore traditional Online Social Networking (OSN) to a great extent by enabling mobile users to benefit from opportunistically created so...

OBJECTIVES The Internet provides great opportunities for patient healthcare education, but poses risks that inaccurate, outdated or harmful information will be disseminated. Our objective was determine the quality of the information available on the internet in relation to oral leukoplakia. STUDY DESIGN Sites were identified using 3 search engines (Google, Yahoo and MSN), and the search term ...

The Drosophila misshapen (msn) gene is a member of the STE20 kinase family. We show that msn acts in the Frizzled (Fz) mediated epithelial planar polarity (EPP) signaling pathway in eyes and wings. Both msn loss- and gain-of-function result in defective ommatidial polarity and wing hair formation. Genetic and biochemical analyses indicate that msn acts downstream of fz and dishevelled (dsh) in ...

Two antigen detection systems (MicroTrak [MT], Syva Co., Palo Alto, Calif.; and Chlamydiazyme [CZ], Abbott Laboratories, North Chicago, Ill.) were compared with semiquantitative culture for diagnosis of chlamydial infection in 1,059 patients. Cultures were done on microtiter plates and blind passaged once. Culture-negative but CZ- or MT-positive specimens were recultured. True positives were po...

The stability of strongly bound excited states of Cat Cz and Cz’ resulting from double excitations of the type aE+MO’ relative to the ground-state configuration (with MO2 standing for 317:, 3a&r” or lx: ) was investigated using a multi-reference MRD-CI method. For Cz, the doubly excited configuration 30~1~: corresponds to the experimentally observed E’C: (3’Z: ) state, which exhibits a heavy mi...

Nitrogen doped Czochralski (N-CZ) and Float Zone (N-FZ) silicon were measured by high resolution synchrotron Fourier Transform IR spectroscopy (HR-FTIR). The chemical complexes were analyzed in specific regions with known extended defects, i.e., denuded or precipitated regions of annealed N-CZ Si wafers, in N-FZ Si with ring defects and on “N-Skin” region. The absorption lines were assigned to ...

To determine the optimal treatment margin of local ablation therapy for small hepatocellular carcinoma (HCC), we investigated characteristics of microscopic satellite HCC nodules (msn) using resected livers, and the incidence of local recurrences in patients who underwent percutaneous microwave coagulation therapy (PMCT) according to whether or not an adequate treatment margin was achieved. We ...

Multidrug resistance (MDR) is the major clinical obstacle in the management of cancer by chemotherapy. Overexpression of ATP-dependent efflux transporter P-glycoprotein (PGP) is a key factor contributing to multidrug resistance of cancer cells. The purpose of the present study was to use the endosomal pH-sensitive MSN (mesoporous silica nanoparticles; MSN-Hydrazone-Dox) for controlled release o...

Feeding of the nickel-based alloys CZ-100, M-35-1, and CW-12MW, as well as of the austenitic stainless steel CN-7M, is investigated, using a combination of casting experiments and simulation. Casting trials are performed at five foundries, to produce a total of 55 plates of varying lengths and radiographic soundness levels. In order to develop the property databases necessary to simulate the ca...
