Predicting Categorical Information for New Content in Application Recommender Systems
Generally, the present disclosure is directed to predicting categorical information for newly created content in an application recommender system. In particular, in some implementations, the systems and methods of the present disclosure can include or otherwise leverage one or more machine-learned models to predict categorical information of new applications in an applications marketplace based on screenshots of such new applications in the applications marketplace
Poly[[[(1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylato)manganese(II)]-μ3-4,4′-oxydibenzoato] monohydrate]
In the title compound, {[Mn(C16H18N3O3)(C14H8O5)]·H2O}n, the unique MnII ion is coordinated by two O atoms from a chelating 1-ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylate ligand and three O atoms from three 4,4′-oxydibenzoate ligands, forming a distorted square-pyramidal coordination environment. In the crystal structure, centrosymmetric dinuclear manganese units are linked via 4,4′-oxydibenzoate ligands into one-dimensional chains; these chains are, in turn, connected via intermolecular N—H⋯O and O—H⋯O hydrogen bonds to form a two-dimensional supramolecular network. The O atom of the solvent water molecule is disordered over two sites with equal occupancies; the attached H atoms are common to both sites
O(\alpha_s) QCD Corrections to Spin Correlations in process at the NLC
Using a Generic spin basis, we present a general formalism of one-loop
radiative corrections to the spin correlations in the top quark pair production
at the Next Linear Collider, and calculate the O(\alpha_s) QCD corrections
under the soft gluon approximation. We find that: (a) in Off-diagonal basis,
the QCD corrections to () scattering
process increase the differential cross sections of the dominant spin component
() by
and depending on the scattering angle for
and 1 TeV, respectively; (b) in {Off-diagonal basis}
(Helicity basis), the dominant spin component makes up 99.8% () of
the total cross section at both tree and one-loop level for ,
and the Off-diagonal basis therefore remains to be the optimal spin basis after
the inclusion of QCD corrections.Comment: 12 pages, 4 figures, revised version (a few print mistakes are

Several Ideas on Fire Detecting Alarm for Power Supply and Distribution System
AbstractThrough the cases of fire in the power supply and distribution system for iron and steel enterprises, the basic causes and the main fire parts for the fire in the power supply and distribution system have been analyzed. Types of fire in the power supply and distribution system are summarized. Several ideas for prevention of fire that will occur in the power supply and distribution system are put forward
