Domain walls, fusion rules and conformal field theory in the quantum Hall regime

We provide a simple way to obtain the fusion rules associated with elementary quasi-holes over quantum Hall wave functions, in terms of domain walls. The knowledge of the fusion rules is helpful in the identification of the underlying conformal field theory describing the wave functions. We obtain the fusion rules, and explicitly give a conformal field theory description, for a two-parameter family (k,r) of wave functions. These include the Laughlin, Moore-Read and Read-Rezayi states when r=2. The `gaffnian' wave function is the prototypical example for r>2, in which case the conformal field theory is non-unitary.Comment: 4 page

APPLICATION OF RECURSIVE PARTITIONING TO AGRICULTURAL CREDIT SCORING

Recursive Partitioning Algorithm (RPA) is introduced as a technique for credit scoring analysis, which allows direct incorporation of misclassification costs. This study corroborates nonagricultural credit studies, which indicate that RPA outperforms logistic regression based on within-sample observations. However, validation based on more appropriate out-of-sample observations indicates that logistic regression is superior under some conditions. Incorporation of misclassification costs can influence the creditworthiness decision.finance, credit scoring, misclassification, recursive partitioning algorithm, Agricultural Finance,

Fractionalization of itinerant anyons in one dimensional chains

We construct models of interacting itinerant non-Abelian anyons moving along one-dimensional chains, focusing in particular on itinerant Ising anyon chains, and derive effective anyonic t-J models for the low energy sectors. Solving these models by exact diagonalization, we find a fractionalization of the anyons into charge and (non-Abelian) anyonic degrees of freedom -- a generalization of spin-charge separation of electrons which occurs in Luttinger liquids. A detailed description of the excitation spectrum by combining spectra for charge and anyonic sectors requires a subtle coupling between charge and anyonic excitations at the microscopic level (which we also find to be present in Luttinger liquids), despite the macroscopic fractionalization.Comment: 5 pages, 3 figure

KALKULASI BIAYA BERDASARKAN AKTIVITAS (ACTIVITY BASED COSTING) SEBAGAI DASAR DALAM PENGHITUNGAN BIAYA POKOK PENYEDIAAN PADA PT. PLN (PERSERO) DISTRIBUSI JATIM APJ BOJONEGORO

Penelitian ini dilaksanakan bertujuan untuk mengimplementasikan sistem informasi biaya berbasis aktivitas (Activity Based Costing ) di PT. PLN (Persero) APJ Bojonegoro, yang merupakan suatu Badan Usaha Milik Negara yang berbentuk Perseroan yang bergerak dibidang jasa pelayanan listrik, ke dalam dua tahap pengolahan data biaya dan operasi dalam ABC system yaitu: Activity Based Process Costing (ABPC) dan Activity Based Object Costing (ABOC). Pemisahan pembahasan dua tahap pengolahan data biaya dan operasi tersebut dimaksudkan untuk mengungkapkan secara jelas manfaat dan keunggulan informasi yang dihasilkan oleh setiap tahap pengolahan dalam pengelolaan organisasi. Dengan ABPC model dapat menghasilkan informasi biaya aktivitas dan informasi tentnag aktivitas sehingga dapat diketahui informasi biaya per aktivitas, sedangkan dengan ABOC model dapat dihasilkan informasi kos produk/ jasa atau Biaya Pokok Penyediaan (BPP) yang akurat. Dalam implementasinya ABC system digunakan sebagai basis di dalam penghitungan Biaya Pokok Penyediaan (BPP) yang menjadi dasar dalam penentuan harga jual ke tipe industri ketenagalistrikan lainnya dan alokasi Biaya Pokok Penyediaan (BPP) dari satu tipe ke tipe industri yang lain dalam sektor ketenagalistrikan merupakan transfer price yang akan menjadi beban bagi tipe industri yang teralokasi.
