    One dimensional M5-brane intersections

    Full text link
    We study one dimensional intersections of M5 branes with M5 and M2 branes. On the worldvolume of the M5-brane, such an intersection appears as a string soliton. We study this worldvolume theory in two different regimes: 1) Where the worldvolume theory is formulated in flat space and 2) where the worldvolume theory is studied in the supergravity background produced by a stack of M5 (or M2) branes. In both cases, we study the corresponding string solitons, and find the most general BPS configuration consistent with the fraction of supersymmetries preserved. We argue that M5 and M2 brane intersections leave different imprints on the worldvolume theory of the intersecting probe brane, although geometrically they appear to be similar.Comment: 13 pages, LaTeX, references adde

    This study aims to determine the effect of various types of bokashi on growth and yield of spinach green giti. The study used Randomized Block Design with three replications. The treatments were several doses bokashi consisting of five levels i.e.: control, bokashi leaves of Gliricidia 40 t/ha, bokashi leaves johar 40 t/ha, bokashi leaves lamtoro 40 t/ha, and bokashi goat manure 40 t/ha. Each treatment were consists of three replicates so that there are 3 x 5 = 15 experimental units. Processing research data conducted by using ANOVA subsequent treatment effect was tested further by the least significant difference test. The results showed that the provision of various types of bokashi not significantly affect the number of leaves, plant height, stem diameter, leaf area, but the real impact on plant fresh weight

    Angka kejadian kanker serviks di Makassar masih cukup tinggi dan menempati urutan kedua setelah Kabupaten Enrekang. Penelitian ini bertujuan untuk mengetahui pola pencarian pengobatan pada penderita kanker serviks di rumah sakit Labuang Baji dan Ibnu Sina Makassar Tahun 2014. Penelitian ini menggunakan rancangan mixed methodology yang menggabungkan dua metode penelitian, yaitu kuantitatif dan kualitatif. Jumlah responden sebanyak 7 orang dan seluruhnya adalah informan, sedangkan informan kunci sebanyak 3 orang. Analisis data yang digunakan untuk desain kuantitatif yaitu analisis univariat dan kualitatif menggunakan model Miles and Huberman. Hasil penelitian menunjukkan sebagian responden mempunyai pengetahuan dan sikap yang positif dalam pencarian pengobatan yaitu masing-masing sebanyak 71.4%, mendapat dukungan keluarga sebanyak 71.4%, dan responden baru mencari pengobatan ketika tingkat keparahannnya telah memasuki stadium lanjut sebanyak 71.4%. Hasil wawancara dengan informan dan informan kunci diperoleh sebagian besar responden mempunyai tingkat pengetahuan yang baik, sikap yang positif, mendapat dukungan dari keluarga, dan media massa berperan dalam pencarian pegobatan penderita kanker serviks, meskipun sebagian responden baru memeriksakan diri ke rumah sakit ketika telah memasuki stadium lanjut. Kesimpulan dari penelitian ini sebagian besar responden tidak hanya menggunakan pengobatan medis tetapi juga pengobatan non medis (tradisional).\ud Kata Kunci: Pengobatan, kanker serviks, mixed methodolog

    The aim of this study was to determine the density, species composition and community structure of makrozoobentos on seagrass areas and its relationship with the percent cover of seagrass in Pulau Bonebatang, Makassar. Data collection on seagrass and makrozoobentos was performed on the same transect (size 1 m2) with 3 replications. Sampling was done on each transect systematically with 20 m distance each other along the line perpendicular to the shore starting from unvegetated area up to the coral area where no more seagrass. Sampling was conducted on four stations (north, south, east and west) of the island based on the presence of seagrass. Percent cover of seagrass and seagrass species observed in each transect were noted. Makrozoobentos obtained were identified to the taxonomic level possible. The study found as many as six seagrass species which were scattered in every station, namely, Thalassia hemprichii, Enhalus acoroides, Halodule uninervis, Halophila ovalis, Syringodium isoetifolium and Cymodocea rotundata, with the percentage of seagrass cover on the island ranged from 50.5 to 74.5 % and classified in good condition. It was found as many as 133 species of macrozoobenthos spread over station consisting of 91 species of gastropods, 22 species of bivalves, 2 species of asteroids, three species of echinoids, 4 species of crustaceans, 8 species of polychaetes, and 3 species of sipunculids. Makrozoobentos highest density was found in the station which has six different seagrass species in which T. hemprichii, C. rotundata, H. ovalis and E. acoroides possess the largest seagrass species composition. The results of correlation analysis showed no relationship between density and number of species of makrozoobentos with the percent cover of seagrass

    A note on bosonic open strings in constant B field

    Get PDF
    We sketch the main steps of old covariant quantization of bosonic open strings in a constant BB field background. We comment on its space-time symmetries and the induced effective metric. The low-energy spectrum is evaluated and the appearance of a new non-commutative gauge symmetry is addressed.Comment: 13 pages, Latex, important comments added, to appear in PR

    Accurate and linear time pose estimation from points and lines

    Get PDF
    The final publication is available at link.springer.comThe Perspective-n-Point (PnP) problem seeks to estimate the pose of a calibrated camera from n 3Dto-2D point correspondences. There are situations, though, where PnP solutions are prone to fail because feature point correspondences cannot be reliably estimated (e.g. scenes with repetitive patterns or with low texture). In such scenarios, one can still exploit alternative geometric entities, such as lines, yielding the so-called Perspective-n-Line (PnL) algorithms. Unfortunately, existing PnL solutions are not as accurate and efficient as their point-based counterparts. In this paper we propose a novel approach to introduce 3D-to-2D line correspondences into a PnP formulation, allowing to simultaneously process points and lines. For this purpose we introduce an algebraic line error that can be formulated as linear constraints on the line endpoints, even when these are not directly observable. These constraints can then be naturally integrated within the linear formulations of two state-of-the-art point-based algorithms, the OPnP and the EPnP, allowing them to indistinctly handle points, lines, or a combination of them. Exhaustive experiments show that the proposed formulation brings remarkable boost in performance compared to only point or only line based solutions, with a negligible computational overhead compared to the original OPnP and EPnP.Peer ReviewedPostprint (author's final draft

    Novel C8orf37 mutations cause retinitis pigmentosa in consanguineous families of Pakistani origin

    Get PDF
    Purpose: To investigate the molecular basis of retinitis pigmentosa in two consanguineous families of Pakistani origin with multiple affected members. Methods: Homozygosity mapping and Sanger sequencing of candidate genes were performed in one family while the other was analyzed with whole exome next-generation sequencing. A minigene splicing assay was used to confirm the splicing defects. Results: In family MA48, a novel homozygous nucleotide substitution in C8orf37, c.244–2A>C, that disrupted the consensus splice acceptor site of exon 3 was found. The minigene splicing assay revealed that this mutation activated a cryptic splice site within exon 3, causing a 22 bp deletion in the transcript that is predicted to lead to a frameshift followed by premature protein truncation. In family MA13, a novel homozygous null mutation in C8orf37, c.555G>A, p.W185*, was identified. Both mutations segregated with the disease phenotype as expected in a recessive manner and were absent in 8,244 unrelated individuals of South Asian origin. Conclusions: In this report, we describe C8orf37 mutations that cause retinal dystrophy in two families of Pakistani origin, contributing further data on the phenotype and the spectrum of mutations in this form of retinitis pigmentosa

    Haldane's Fractional Statistics and the Lowest Landau Level on a Torus

    The Lowest Landau Level on a torus is studied. The dimension of the many-body Hilbert space is obtained and is found to be different from the formula given by Haldane. Our result can be tested in numerical investigations of the low-energy spectrum of fractional quantum Hall states on a torus.Comment: 4 pages, Revtex. Small modifications.
