The dyon charge in noncommutative gauge theories

We present an explicit classical dyon solution for the noncommutative version of the Yang-Mills-Higgs model (in the Prasad-Sommerfield limit) with a tehta term. We show that the relation between classical electric and magnetic charges also holds in noncommutative space. Extending the Noether approach to the case of a noncommutative gauge theory, we analyze the effect of CP violation at the quantum level, induced both by the theta term and by noncommutativity and we prove that the Witten effect formula for the dyon charge remains the same as in ordinary space.Comment: 17 page

When Big Isn’t Better: Why Smaller International Initial Public Offering Firms Seem to Win

There is a considerable amount of research suggesting that “being international” is better. While that may be the case, the assumption remains tenuous at best, and research that considers organizational size provides results contesting this assumption. In particular, we explore the effect of having international sales and operations on both long and short-term performance of initial public offering (IPO) firms. We also explore the “size” phenomenon evident in prior research that suggests smaller firms seem to perform better when they are international than do medium size firms. By applying work from the field of human resource management, we suggest that the ‘size’ phenomenon may be related to the level of structural cohesion in the organization. Our longitudinal study supports the hypothesis that international companies with higher levels of structural cohesion are more successful

Vector boson production at hadron colliders: a fully exclusive QCD calculation at NNLO

We consider QCD radiative corrections to the production of W and Z bosons in hadron collisions. We present a fully exclusive calculation up to next-to-next-to-leading order (NNLO) in QCD perturbation theory. To perform this NNLO computation, we use a recently proposed version of the subtraction formalism. The calculation includes the gamma-Z interference, finite-width effects, the leptonic decay of the vector bosons and the corresponding spin correlations. Our calculation is implemented in a parton level Monte Carlo program. The program allows the user to apply arbitrary kinematical cuts on the final-state leptons and the associated jet activity, and to compute the corresponding distributions in the form of bin histograms. We show selected numerical results at the Tevatron and the LHC.Comment: 7 pages, 3 ps figure

Dirac Quantization Condition for Monopole in Noncommutative Space-Time

Since the structure of space-time at very short distances is believed to get modified possibly due to noncommutativity effects and as the Dirac Quantization Condition (DQC), $\mu e = \frac{N}{2}\hbar c$, probes the magnetic field point singularity, a natural question arises whether the same condition will still survive. We show that the DQC on a noncommutative space in a model of dynamical noncommutative quantum mechanics remains the same as in the commutative case to first order in the noncommutativity parameter $\theta$, leading to the conjecture that the condition will not alter in higher orders.Comment: 11 page

Kajian Perbedaan Konsentrasi Larutan Garam Pada Perendaman Rgh Dan Vaksin Terhadap Kelulushidupan Dan Pertumbuhan Benih Ikan Lele Sangkuriang (Clarias Gariepinus)

Berdasarkan data KKP (2013), pencapaian produksi ikan lele pada tahun 2013 mampu melampaui target. Ikan lele merupakan ikan yang mudah dibudidayakan, sehingga banyak dilakukan penelitian agar didapatkan benih lele dengan pertumbuhan dan kelulushidupan yang lebih baik, serta tahan terhadap serangan penyakit. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi larutan garam yang berbeda dan konsentrasi yang terbaik pada perendaman rGH dan vaksin terhadap kelulushidupan dan pertumbuhan benih lele sangkuriang. Penelitian ini dilaksanakan pada tanggal 13 November 2014 – 15 Februari 2015 di Satuan Kerja Pembenihan dan Budidaya Ikan Air Tawar (SATKER PBIAT), Siwarak, Ungaran, Semarang. Ikan uji yang digunakan adalah benih lele sangkuriang umur 12 hari. Metode yang digunakan adalah eksperimental dengan rancangan acak lengkap (RAL) 4 perlakuan dan 3 ulangan, yaitu: (A) perlakuan tanpa larutan garam, (B) konsentrasi 0,5%, (C) konsentrasi 1,0% dan (D) konsentrasi 1,5%. Pemeliharaan ikan dilakukan selama 42 hari. Variabel data yang diamati meliputi kelulushidupan, SGR, panjang mutlak, FCR, EPP dan kelulushidupan setelah uji tantang. Analisa data dengan menggunakan anova untuk mengetahui pengaruh perlakuan yang berbeda nyata, apabila hasil yang didapatkan berbeda nyata, maka dilanjutkan dengan uji duncan untuk mengetahui perlakuan yang terbaik. Hasil penelitian menunjukkan perlakuan terbaik adalah perlakuan C, dengan nilai kelulushidupan (87,00±1,00%), SGR (7,79±0,03%), nilai panjang mutlak (6,75±0,15cm), nilai FCR (0,71±0,01) dan nilai EPP (140,28±1,25%), sedangkan untuk kelulushidupan setelah uji tantang didapatkan hasil yang tidak berbeda nyata, dimana: A (93,33±5,77%), B (96,67±5,77%), C (96,67±5,77%) dan D (96,67±5,77%). Kesimpulan dari penelitian ini ialah pemberian konsentrasi larutan garam yang berbeda berpengaruh sangat nyata terhadap kelulushidupan, SGR, panjang mutlak, FCR dan EPP, namun tidak berpengaruh nyata terhadap kelulushidupan setelah uji tantang. Konsentrasi larutan garam terbaik pada penelitian ini adalah 1,0%. Based on data from KKP (2013), the achievement of the production of catfish in 2013 was able of exceeding the target. Catfish is a fish that easily cultivated, so a lot of research done to get catfish\u27s seed with better survival and growth, and it can resistant to attack of deseases.

The conclusion of this research is giving of salt solution with different concentration take significantly effect for survival rate, SGR, absolute length, FCR and EPP, but did not take significantly effect for survival rate after challenge test. The best salt solution concentration is 1.0%

East and West, past and present : rekindle old principles for new management practices

This paper explores the sayings and stories of the ancient Chinese philosophers Guanzi, Hanfeizi, Xunzi and Yanzi. Their way of ruling the state and managing the people are analysed and discussed in line with thoughts from the mainstream and modern Western management gurus, such as Warren Bennis, Peter Drucker, Mary Parker Follett, Douglas McGregor, Rosabeth Moss Kanter, Elton Mayo, and Jeffrey Pfeffer. Striking similarities call for addressing key issues in human resource management. East and west thinkers across 3000 years are identified. The principles-based ruling and management were found difficult to be taken seriously in ancient times as it is today. However, these principles must be rekindled to protect organisations and the world from mischievous behaviour that has caused much human suffering.<br /

The Dyon Charge in Noncommutative Gauge Theories

We construct a dyon solution for the noncommutative version of the Yang-Mills-Higgs model with a ϑ-term. Extending the Noether method to the case of a noncommutative gauge theory, we analyze the effect of CP violation induced both by the ϑ- term and by noncommutativity proving that theWitten effect formula for the dyon charge remains the same as in ordinary space.Facultad de Ciencias Exacta
