Coordinate gradient learning is motivated by the problem of variable selection and determining variable covariation. In this paper we propose a novel unifying framework for coordinate gradient learning (MGL) from the perspective of multi-task learning. Our approach relies on multi-task kernels to simulate the structure of gradient learning. This has several appealing properties. Firstly, it all...

Chemiluminescent reactions of metastable Mg*(Pj) atoms with F2, Cl2, Br2, I2, IC1, IBr molecules were studied in a beam-gas experiment. For all homonuclear targets the MgX(A FI X X) emission was observed, but for IC1 and IBr reactants the Mgl(A-X) emission was absent and only MgCl(A-X) or MgBr(A-X) spectra were found. In addition, for the I2, IBr, IC1, Br2 reactions, broad pseudocontinua extend...

Background & Aim: Effects of ultra violet spectrum on plants due to their obligatory requirement for sunlight for survival are unavoidable. Direct effects of UV on plant growth and development are generally negative and usually they use many different defense mechanisms to acclimate and protect themselves. Material & Methods: The present research for the first time was conducted to investigate...

  The acute toxicity and effects of diazinon on some haematological parameters of kutum (Rutilus frisii kutum, Kamensky, 1901) weighing 613.33 ± 157.06 g were studied under static water quality conditions at 15 °C ± 2 ºC. These experiments were carried out based on the standard TRC, 1984 method over 4 days, and controlled for the effective water physicochemical factors having pH rangesof 7-8.2,...

Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...
