Notes on D-branes of Type IIB String on AdS_5 x S^5

We promote a study of D-branes of type IIB string on the AdS_5 x S^5 background. The possible D-branes preserving half of supersymmetries were classified up to and including the fourth order of fermionic variable \th in our previous work [hep-th/0310228]. In this paper we show that our classification is still valid even at the full order of \th. This proof supplements our previous results and completes the classification of D-branes in the type IIB string theory on the AdS_5 x S^5.Comment: 11 pages, no figures, LaTe

Geometry of the Nonabelian DBI Dyonic Instanton

We introduce a calculus of the Lie algebra valued functions present in Tseytlin's proposal for the nonabelian DBI action, and apply it to show that the recently found dyonic instanton is a solution of the full nonabelian DBI action. The geometry of this solution exhibits a new effect of ``blowing-up'' of the brane, which was not present in the case of the brane realisation of monopoles. We interpret this solution as the superposition of the D0 brane and fundamental string F1 which connects two separated D4 branes. Both F1 and D0 are delocalised in the ``blown-up'' region between two separated D4 branes.Comment: 14 pages, 3 figures; v2: minor changes and added reference

Dirichlet Branes of the Covariant Open Supermembrane in AdS_4 x S^7 and AdS_7 x S^4

We discuss an open supermembrane theory in the AdS_4 x S^7 and AdS_7 x S^4 backgrounds. The possible Dirichlet branes of an open supermembrane are classified by analyzing the covariant Wess-Zumino term. All of the allowed configurations are related to those on the pp-wave background via the Penrose limit.Comment: 16 pages, LaTeX, some clarifications and references adde

osp(1|32) and Extensions of super-AdS_5 X S^5 algebra

The super-AdS_5 X S^5 and the four-dimensional N=4 superconformal algebras play important roles in superstring theories. It is often discussed the roles of the osp(1|32) algebra as a maximal extension of the superalgebras in flat background. In this paper we show that the su(2,2|4), the super-AdS_5 X S^5 algebra or the superconformal algebra, is not a restriction of the osp(1|32) though the bosonic part of the former is a subgroup of the latter. There exist only two types of u(1) extension of the super-AdS_5 X S^5 algebra if the bosonic AdS_5 X S^5 covariance is imposed. Possible significance of the results is also discussed briefly.Comment: 20 pages, LaTeX, references adde

Pengembangan Lembar Kerja Siswa (LKS) Sejarah dalam Upaya Meningkatkan Hasil Belajar Aspek Psikomotorik Siswa Kelas XI SMA Negeri 1 Kaliwungu Tahun Pelajaran 2016/2017

Tujuan dari penelitian ini antara lain: (1) mengetahui tentang kelayakan pengembangan LKS Sejarah dalam pembelajaran sejarah, (2) mengetahui peningkatan hasil belajar aspek psikomotorik siswa kelas XI di SMA Negeri 1 Kaliwungu setelah menggunakan LKS. Metode penelitian yang digunakan yaitu penelitian dan pengembangan atau Research and Development (R&D) yang telah disederhanakan. Untuk mengetahui kelayakan LKS dapat dilihat dari hasil validasi yang dilakukan oleh ahli materi dan ahli media, guru dan peserta didik. Kelayakan dari ahli materi menunjukkan nilai 100% (ukuran LKS dan desain sampul LKS), nilai 66,67% (penyajian LKS) oleh validator media. Sedangkan nilai 100% untuk semua komponen oleh validator materi setalah dilakukan revisi. Dari hasil respon siswa mendapatkan nilai rata-rata 84,56% (penyajian LKS) dan nilai 82,83% (penilaian LKS dalam pembelajaran). Sedangkan untuk mengetahui peningkatan hasil belajar aspek psikomotorik peserta didik dapat dilihat dari data pretest dan post test kelas eksperimen yaitu 14,972 (pretest) dan 16,81 (post test) yang memiliki rata-rata lebih tinggi dibandingkan data pretest dan post test peserta didik kelas kontrol yaitu 14,294 (pretest) dan 16,74 (post test)

Self Running Droplet: Emergence of Regular Motion from Nonequilibrium Noise

Spontaneous motion of an oil droplet driven by chemical nonequilibricity is reported. It is shown that the droplet undergoes regular rhythmic motion under appropriately designed boundary conditions, whereas it exhibits random motion in an isotropic environment. This study is a novel manifestation on the direct energy transformation of chemical energy into regular spatial-motion under isothermal conditions. A simple mathematical equation including noise reproduces the essential feature of the transition from irregularity into periodic regular motion. Our results will inspire the theoretical study on the mechanism of molecular motors in living matter, working under significant influence of thermal fluctuation.Comment: 4 pages, 4 figure

Dirichlet Branes of the Covariant Open Supermembrane on a PP-wave Background

We discuss an open supermembrane theory on the maximally supersymmetric pp-wave background in eleven dimensions. The boundary surfaces of an open supermembrane are studied by using the covariant supermembrane theory. In particular, we find the configurations of M5-branes and 9-branes preserving a half of supersymmetries at the origin.Comment: 17 pages, no figures, LaTeX2e, minor correction, references added.

p-branes on the waves

We present a large family of simple, explicit ten-dimensional supergravity solutions describing extended extremal supersymmetric Ramond-Ramond p-branes embedded into time-dependent dilaton-gravity plane waves of an arbitrary (isotropic) profile, with the brane world-volume aligned parallel to the propagation direction of the wave. Generalizations to the non-extremal case are not analyzed explicitly, but can be pursued as indicated.Comment: 11 pages; v.2 minor notation changes, minor typos corrected (published version
