LeaDen-Stream: A Leader Density-Based Clustering Algorithm over Evolving Data Stream  [PDF]

Clustering evolving data streams is important to be performed in a limited time with a reasonable quality. The existing micro clustering based methods do not consider the distribution of data points inside the micro cluster. We propose LeaDen-Stream (Leader Density-based clustering algorithm over evolving data Stream), a density-based clustering algorithm using leader clustering. The algorithm is based on a two-phase clustering. The online phase selects the proper mini-micro or micro-cluster leaders based on the distribution of data points in the micro clusters. Then, the leader centers are sent to the offline phase to form final clusters. In LeaDen-Stream, by carefully choosing between two kinds of micro leaders, we decrease time complexity of the clustering while maintaining the cluster quality. A pruning strategy is also used to filter out real data from noise by introducing dense and sparse mini-micro and micro-cluster leaders. Our performance study over a number of real and synthetic data sets demonstrates the effectiveness and efficiency of our method.

Abstract: The main object of this study was to evaluate the treatment of the patients at early stages of nodular form of leishmaniasis by intralesional injection of sodium stibogluconate (Pentostam). The study shows that the method recommended by WHO expert committee gives satisfactory results in nodular form in Iran.

Abstract: A list of 28 patients is given in whom the duration of the sore at the site of leishmanization has been 3 to 7 years. The problem of cases of cutaneous leishmanjasis with long duration as a complication of leishmanization is discussed. Although this complication is very rare, i.e. a few hundreds among more than 2 million people inoculated, its effect on the leishmanization program has been Considerable as reflected in reports by dermatologists the situations in which leishmanization is recommended is discussed.
The second decade
M. Amini
Iranian Journal of Physics Research , 2004,
Abstract: It is ten years since the Iranian Journal of Physics Research has been in publication. For the Occasion of the 10th anniversary of its publication, we have planned several changes and modifications. These includes increasing the annual issues to four and omission of Introduction of Previously-Published Papers in International Journals section. In this article some statistical information of the published articles is given together with the index of the journals referees. As we enter the second decade of our publication, we face several questions. In this article we share these questions with our readers in the hope of finding the best possible solutions, so that we would be able to publish a better journal in future.

Abstract: Background and Objectives: Sub inhibitory concentrations (sub-MICs) of antibiotics, although unable to kill bacteria, can modify their physiologic and biochemical integrity and may to some extent interfere with some bacterial functions."nMaterials and Methods: In this study the effect of penicillin, vancomycin, and ceftazidime were evaluated on two pathogenic and commonly encountered bacterial species in clinical practice. The test bacterial strains included Staphylococcus aureus ATCC 29213 and Pseudomonas aeruginosa ATCC 2783. In this study, coagulase and DNase activity, mannitol fermentation and morphologic change of S. aureus and oxidase activity, pigment production and morphologic change of P. aeruginosa were evaluated."nResults: Except for some changes in the morphology being apparent as enlarged and undivided cocci in 1/2 to 1/8 sub MIC of all above-mentioned antibiotics, S. aureus showed no change in any of its properties, like coagulase and DNase production and mannitol fermentation. In P.aeuginosa, except for some morphologic changes, i.e. elongation and filamentation, in 1/2 to 1/8 dilution of ceftazidime, no further changes were observed."nConclusion: Exposure of bacteria to sub MICs of antibiotic can produce some detectable morphologic changes without any alteration in other biochemical properties.
Physiological Race of Fusarium oxysporum F. sp. Lycopersici in Kurdistan Province of Iran and Reaction of Some Tomato Cultivars to Race 1 of Pathogen

Plant Pathology Journal , 2009,
Abstract: In this research, eleven isolates of Fusarium oxysporum were collected from tomato plants displaying wilt symptoms in fields in Kurdistan province. Race 1 of pathogen was obtained from Moscow Timiryazev Agricultural Academy in Russia. Pathogenicity of the collected isolates and race 1 of the pathogen were evaluated in glasshouse conditions. Pathogenicity tests and race determination were conducted using root-dip inoculation with different tomato cultivars, Beliy naliv-241 (not resistant), Blagovest (resistant to race 1) and Benito (resistant to both races of 1 and 2). The experimental design was a completely randomized type with six replications (pots) containing two seedlings per pot. Disease severity was measured five weeks following inoculation by using a scale of 0 to 4. The criteria used to assess the response of different cultivars were; leaf disease index, plant height and vascular discoloration index. Results showed that Beliy naliv-241 lacking any resistance gene wilted four weeks after inoculation, but cultivars Blagovest and Benito did not develop symptoms to any of the isolates tested. The reaction of race 1 and the Iranian isolates were similar in pathogenicity suggesting that all of the isolates belong to Fusarium f. sp. lycopersici race 1. Also, Reaction 23 tomato cultivars against to F. o. f. sp. lycopersici indicated that 6 of the them were resistant, 5 were intermediately resistant, 6 were tolerant, 3 were susceptible and the rest 3 were found to be very susceptible.

Control-target inversion property on Abelian groups

Physics , 2003,
Abstract: We show that the quantum Fourier transform on finite fields used to solve query problems is a special case of the usual quantum Fourier transform on finite abelian groups. We show that the control/target inversion property holds in general. We apply this to get a sharp query complexity separation between classical and quantum algorithms for a hidden homomorphism problem on finite Abelian groups.
