Representation systems have been widely used to capture different forms of incomplete data in various settings. However, existing representation systems are not expressive enough to handle the more complex scenarios of missing data that can occur in practice: these could vary from missing attribute values, missing a known number of tuples, or even missing an unknown number of tuples. In this wo...

The title compound, strontium trimanganese tris-(ortho-phosphate), was synthesized under hydro-thermal conditions. Its structure is isotypic to that of the lead analogue PbMn(II) 2Mn(III)(PO4)3. Two O atoms are in general positions, whereas all others atoms are in special positions. The Sr and one P atom exhibit mm2 symmetry, the Mn(II) atom 2/m symmetry, the Mn(III) atom and the other P atom ....

We report here a new and fast approach [Transferable Partial Atomic Charge Model (TPACM4)-upto four bonds] for deriving the partial atomic charges of small molecules for use in protein/DNA-ligand docking and scoring. We have created a look-up table of 5302 atom types to cover the chemical space of C, H, O, N, S, P, F, Cl, and Br atoms in small molecules together with their quantum mechanical RE...

The title compound, barium trimanganese tris-(ortho-phosphate), was synthesized hydro-thermally. Its structure is isotypic with the lead and strontium analogues AMn(II) 2Mn(III)(PO4)3 (A = Pb, Sr). Except for two O atoms on general positions, all atoms are located on special positions. The Ba and one P atom exhibit mm2 symmetry, the Mn(II) atom 2/m symmetry, the Mn(III) atom and the other P ato...

In this paper we propose recurrent neural networks with feedback into the input units for handling two types of data analysis problems On the one hand this scheme can be used for static data when some of the input variables are missing On the other hand it can also be used for sequential data when some of the input variables are missing or are available at di erent frequencies Unlike in the cas...

Random forest (RF) missing data algorithms are an attractive approach for imputing missing data. They have the desirable properties of being able to handle mixed types of missing data, they are adaptive to interactions and nonlinearity, and they have the potential to scale to big data settings. Currently there are many different RF imputation algorithms, but relatively little guidance about the...

According to the previous study, the printability of electromechanical engraved cylinder and laser engraved cylinder were different in terms of density, tone reproduction and mottle. In this study, the missing dots of two different engraved cell types were investigated. It showed that different cell structures had strong effect to ink transferring and the characteristics of missing dots. Lasers...
