چکیده

Scrutiny of an established monoclinic magnetic space group for NdFeO3 reveals hitherto unknown properties the orthoferrite. Future experiments using neutron and x-ray diffraction techniques can verify them. Neodymium ions possess Dirac multipoles, both time-odd (magnetic) parity-odd (polar), that come with unique conditions. Non-magnetic polar Nd multipoles are permitted even though is centrosymmetric. forbidden by symmetry at sites occupied ferric ions. Available patterns have not been analysed multipoles. Nor all components axial dipoles quadrupoles. In case diffraction, quadrupoles correlations between anapole orbital degrees freedom. We give conditions observation Templeton-Templeton scattering x-rays, created angular anisotropy in electronic charge distribution. Axial sole providers dichroic signals.

Structural , Magnetic , and Optical Properties of Orthoferrite Thin Films

Pulsed laser deposition was used to create thin films of Ce-Fe-O and Y-Fe-O systems. Deposition temperature and ambient oxygen pressure were varied systematically between samples to determine which deposition conditions were most favorable to the formation of cerium/yttrium orthoferrite. The structure and composition of each film were then determined using X-ray diffraction and wavelength dispe...

Stochastic Motif Extraction Using Hidden Markov Model

In this paper, we study the application of an HMM (hidden Markov model) to the problem of representing protein sequences by a stochastic motif. A stochastic protein motif represents the small segments of protein sequences that have a certain function or structure. The stochastic motif, represented by an HMM, has conditional probabilities to deal with the stochastic nature of the motif. This HMM...

Magnetic Charge as a “Hidden” Gauge Symmetry

A theory containing both electric and magnetic charges is formulated using two vector potentials, A and C. This has the aesthetic advantage of treating electric and magnetic charge both as gauge symmetries, but it has the experimental disadvantage of introducing a second massless gauge boson (the “magnetic” photon) which is not observed. This problem is dealt with by using the Higgs mechanism t...

Finding Genes by Hidden Markov Models with a Protein Motif Dictionary

A new method for combining protein motif dictionary to gene nding system is proposed. The system consists of Hidden Markov Models (HMMs) and a dictionary. The HMMs represents the nucleotide acid bases, the codons, and the amino acids. The 'words' in the dictionary is described by the sequence of these HMMs and represent the noncoding regions, the codons, protein motifs, tRNA regions and signals...
