A Perturbative QCD Based Study of Polarized Nucleon Structure in the Transition Region and Beyond: "Quarks, Color Neutral Clusters, and Hadrons"

A large fraction of the world data on both polarized and unpolarized inclusive $ep$ scattering at large Bjorken $x$ lies in the resonance region where a correspondence with the deep inelastic regime, known as Bloom and Gilman's duality, was observed. Recent analyses of the $Q^2$ dependence of the data show that parton-hadron duality is inconsistent with the twist expansion at low values of the final state invariant mass. We investigate the nature of this disagreement, and we interpret its occurrence in terms of contributions from non partonic degrees of freedom in a preconfinement model.Comment: 5 pages, 1 figure, to be published in the Proceedings of the "3rd International Symposium on the Gerasimov-Drell-Hearn Sum Rule and its Extensions", Editors, J.P.

ANALISIS KEMENANGAN LEE CHONG WEI DALAM PERTANDINGAN MELAWAN CHEN LONG

ANALISIS KEMENANGAN LEE CHONG WEI DALAM PERTANDINGAN MELAWAN CHEN LONG Fajar Ahsani ABSTRAK Olahraga Bulutangkis merupakan olahraga yang paling digemari di Indonesia setelah sepakbola. Bulutangkis adalah olahraga yang dimainkan oleh dua orang (untuk tunggal) atau dua pasang (untuk ganda), untuk memainkan olahraga ini kita harus mengetahui teknik-teknik dasar seperti servisforehand pendek, servisforehand tinggi, underhand, lob, smash, dropshot, netting dan juga backhand. Penelitian ini merupakan penelitian analisis deskriptif untuk mengetahui teknik yang digunakan Lee Chong Wei dan Chen Long dalam Pertandingan Yonex sunrise Hongkong Open 20 November 2015, Celcom Axiata Malaysia Open 10 April 2016, dan Dong Feng Citroen Badminton Asia Championships 1 Mei 2016. Dari hasil penelitian analisis kemenangan Lee Chong Wei dalam pertandingan melawan Chen Long menunjukkan bahwa dalam 3 pertemun Lee Chong Wei mendominasi jalannya permainan. Serangan Lee Chong Wei lebih tersusun rapi daripada serangan Chen Long, serangan Lee Chong Wei dimulai dengan teknik servisforehand pendek, netting, dan smash. Chen Long sering kehilangan konsentrasi jika sudah terkena serangan Lee Chong Wei. Kata kunci: Analisis, Bulutangkis, Pertandingan Bulutangkis, Teknik bulutangkis. ANALYSIS LEE CHONG WEI’S GLORY IN A GAMES AGAINST CHEN LONG FajarAhsani ABSTRACT Badminton is a sport that is most popular in Indonesia after football.Badminton is played by two people (for a single) or two pairs (for a double), to play this sport we need to know the basic techniques such asshort fore hand service, high forehand service, underhand, lob, smash, dropshot, netting, and also backhand. This research is a descriptive analysis to know about Lee Chong Wei’s technique and Chen Long’s technique in the gameYonex sunrise Hong Kong Open November 20th 2015,Celcom Axiata Malaysia Open April 10th2016,andDong Feng Citroen Badminton Asia Championships May 1th, 2016. From the analysis research Lee Chong Wei’s glory in the games against Chen Long showed that within 3 during the meeting, Lee Chong Wei dominated the games. Lee Chong Wei attack more neatly than Chen Long’s attack, Lee Chong Wei’s attack began with a short forehand service techniques, netting, and smash. Chen Long often lose concentration if it had been hit by Lee Chong Wei. Keywords: Analysis, Badminton, Badminton Games, Badminton Techniques

Generalized reduction criterion for separability of quantum states

A new necessary separability criterion that relates the structures of the total density matrix and its reductions is given. The method used is based on the realignment method [K. Chen and L.A. Wu, Quant. Inf. Comput. 3, 193 (2003)]. The new separability criterion naturally generalizes the reduction separability criterion introduced independently in previous work of [M. Horodecki and P. Horodecki, Phys. Rev. A 59, 4206 (1999)] and [N.J. Cerf, C. Adami and R.M. Gingrich, Phys. Rev. A 60, 898 (1999)]. In special cases, it recovers the previous reduction criterion and the recent generalized partial transposition criterion [K. Chen and L.A. Wu, Phys. Lett. A 306, 14 (2002)]. The criterion involves only simple matrix manipulations and can therefore be easily applied.Comment: 17 pages, 2 figure

Four seasons: A study of Chen Yi's Si Ji

The purpose of this study is to draw attention to the hybrid of Eastern and Western musical elements, in Chen Yi???s orchestral work Si Ji. In this dissertation, Chen Yi???s Si Ji will be thoroughly discussed by a detailed analysis of the work as well as the background of Chen Yi???s musical world, and the poetry she is inspired by. It will show how the music produces a hybrid of East and West. I hope this dissertation will serve as a valuable source for other composers seeking their own musical colors, as well as researchers interested in the crossing of Eastern and Western music

Comment on "Quantum discord through the generalized entropy in bipartite quantum states"

In [X.-W. Hou, Z.-P. Huang, S. Chen, Eur. Phys. J. D 68, 1 (2014)], Hou et al. present, using Tsallis' entropy, possible generalizations of the quantum discord measure, finding original results. As for the mutual informations and discord, we show here that these two types of quantifiers can take negative values. In the two qubits instance we further determine in which regions they are non-negative. Additionally, we study alternative generalizations on the basis of R\'enyi entropies.Comment: 5 pages, 4 figure
