Subspace clustering assumes that the data is separable into separate subspaces. Such a simple assumption, does not always hold. We assume that, even if raw subspaces, one can learn representation (transform coefficients) such learnt To achieve intended goal, we embed subspace techniques (locally linear manifold clustering, sparse and low rank representation) transform learning. The entire formu...

SUMMARY Normal contact-inhibited and transformed cell cultures have been fixed and embedded in situ for an electron microscopic study of the cell surface and intercellular connections. In a number of experiments, ruthenium red was added to the fixa tives following Luft's technic for visualizing the mucopoly saccharide layer on the cell surface. Cultures of normal rat, Chinese and Syrian hamster...

An electrochemical study using the cyclic voltammetry method was carried out on some previously prepared merocyanines salts, namely thiazolideniumsulfonate salts 5a-b, and thiazolidenium chloride 6a-b, merocarbocyanines alkylidenthiazolidenium sulfonate salt 5c, 6c. These are transformed by dimerization in situ a voltammetric cell into tetrathiatetraazafulvalenes (TTTAFs) 7a-b, 7’a-b, 8c, 8'c s...

This study was performed for the detection of cocarcinogens by transformation in vitro with the use of a subclone of a Balb/3T3 cell line. Dose response, cytotoxicity, and transformation studies were done with the use of an indirect-acting carcinogen, benzo[a]pyrene (B[a]P), a direct-acting alkylating carcinogen, beta-propiolactone (BPL), and the mouse skin cocarcinogen catechol. The rate of tr...

Natural killer (NK) cells kill normal and transformed hematopoietic cells that lack expression of major histocompatibility complex (MHC) class I antigens. Lysis of HLA-negative Epstein Barr virus-transformed B lymphoblastoid call lines (B-LCL) by human NK cell clones can be inhibited by transfection of the target cells with certain HLA-A, -I3, or -C alleles. NK cell clones established from an i...
