Some Theorems for Feed Forward Neural Networks [PDF]
, 2015 In this paper we introduce a new method which employs the concept of "Orientation Vectors" to train a feed forward neural network and suitable for problems where large dimensions are involved and the clusters are characteristically sparse. The new method

Topological barriers for locally homeomorphic quasiregular mappings in 3-space
, 2017 We construct a new type of locally homeomorphic quasiregular mappings in the 3-sphere and discuss their relation to the M.A.Lavrentiev problem, the Zorich map with an essential singularity at infinity, the Fatou's problem and a quasiregular analogue of ...

Transmission-electron-microscopy study of charge-stripe order in La(1.725)Sr(0.275)NiO(4)
, 2002 We characterize the local structure and correlations of charge stripes in La(1.725)Sr(0.275)NiO(4) using transmission-electron microscopy. We present direct evidence that the stripe modulation is indeed one-dimensional within each NiO(2) plane ...

Topological phases protected by point group symmetry [PDF]
, 2017 We consider symmetry protected topological (SPT) phases with crystalline point group symmetry, dubbed point group SPT (pgSPT) phases. We show that such phases can be understood in terms of lower-dimensional topological phases with on-site symmetry, and ...

Unconventional superconducting gap structure protected by space group symmetry
, 2018 Recent superconducting gap classifications based on space group symmetry have revealed nontrivial gap structures that were not shown by point group symmetry.

, 2017 Metal crystals with tetrahedral packing are known as Frank-Kasper phases with large unit cells with the number of atoms from hundreds to thousands. The main factors of the formation and stability of these phases are the atomic size ratio and the number ...

Dynamics of Attention in Depth: Evidence from Mutli-Element Tracking [PDF]
, 1999 The allocation of attention in depth is examined using a multi-element tracking paradigm. Observers are required to track a predefined subset of from two to eight elements in displays containing up to sixteen identical moving elements. We first show that

Structure optimization effects on the electronic properties of Bi$_2$Sr$_2$CaCu$_2$O$_8$
, 2003 We present detailed first-principles calculations for the normal state electronic properties of the high T$_C$ superconductor Bi$_2$Sr$_2$CaCu$_2$O$_8$, by means of the linearized augmented plane wave (LAPW) method within the framework of density ...

Interplay between proton ordering and ferroelectric polarization in H-bonded KDP-type crystals
, 2000 The origin of ferroelectricity in KH_2PO_4 (KDP) is studied by first-principles electronic structure calculations. In the low-temperature phase, the collective off-center ordering of the protons is accompanied by an electronic charge delocalization from ...
