In this paper, we suggest genetic algorithm based method which searches several solution spaces simultaneously. The solution spaces are population groups consisting of elements with similar structure. Elements in a group have the same size, while elements in different groups are of different sizes. The proposed algorithm processes the population in groups of chromosomes with one gene, two genes to k genes. These genes hold corresponding information about the cluster centers. In the proposed method, the crossover and mutation operators can accept parents with different sizes; this can lead to versatility in population and information transfer among sub-populations. We implemented the proposed method and evaluated its performance against some random datasets and the Ruspini dataset as well. The experimental results show that the proposed method could effectively determine the appropriate number of clusters and recognize their centers. Overall this research implies that using heterogeneous population in the genetic algorithm can lead to better results.}, language = {en} } @misc{AlhosseiniAlmodarresiYasinBinTareafNajafietal.2019, author = {Alhosseini Almodarresi Yasin, Seyed Ali and Bin Tareaf, Raad and Najafi, Pejman and Meinel, Christoph}, title = {Detect me if you can}, series = {Companion Proceedings of The 2019 World Wide Web Conference}, journal = {Companion Proceedings of The 2019 World Wide Web Conference}, publisher = {Association for Computing Machinery}, address = {New York}, isbn = {978-1-4503-6675-5}, doi = {10.1145/3308560.3316504}, pages = {148 -- 153}, year = {2019}, abstract = {Spam Bots have become a threat to online social networks with their malicious behavior, posting misinformation messages and influencing online platforms to fulfill their motives. As spam bots have become more advanced over time, creating algorithms to identify bots remains an open challenge. Learning low-dimensional embeddings for nodes in graph structured data has proven to be useful in various domains. In this paper, we propose a model based on graph convolutional neural networks (GCNN) for spam bot detection. Our hypothesis is that to better detect spam bots, in addition to defining a features set, the social graph must also be taken into consideration. GCNNs are able to leverage both the features of a node and aggregate the features of a node's neighborhood. We compare our approach, with two methods that work solely on a features set and on the structure of the graph. To our knowledge, this work is the first attempt of using graph convolutional neural networks in spam bot detection.}, language = {en} } @misc{AlbrechtClassGoebeletal.2020, author = {Albrecht, Sophia and Class, Fabian and Goebel, Jan and Kohler, Ulrich and Krawietz, Marian}, title = {Leben in der ehemaligen DDR}, series = {SOEP Survey Papers}, journal = {SOEP Survey Papers}, publisher = {German Institute for Economic Research (DIW Berlin)}, address = {Berlin}, year = {2020}, language = {de} } @misc{AlbrechtClassFeuersteinetal.2020, author = {Albrecht, Sophia and Class, Fabian and Feuerstein, Collin and Kohler, Ulrich and Krawietz, Marian}, title = {The Potsdam grievance statistics file (PGSF)}, doi = {10.4232/1.13615}, year = {2020}, abstract = {Der Potsdam Grievance Statistics File (PGSF) ist eine historische Datensammlung von Beschwerden, sog.

To suppress plant immunity and cause disease P.syringae injects type-III effector proteins (T3Es) into the plant cell cytosol. In this study, we identified a novel target of the well characterized bacterial T3E HopZ1a. HopZ1a is an acetyltransferase that was shown to disrupt vesicle transport during innate immunity by acetylating tubulin. Using a yeast-two-hybrid screen approach, we identified a REMORIN (REM) protein from tobacco as a novel HopZ1a target. HopZ1a interacts with REM at the plasma membrane (PM) as shown by split-YFP experiments. Interestingly, we found that PBS1, a well-known kinase involved in plant immunity also interacts with REM in pull-down assays, and at the PM as shown by BiFC. Furthermore, we confirmed that REM is phosphorylated by PBS1 in vitro. Overexpression of REM provokes the upregulation of defense genes and leads to disease-like phenotypes pointing to a role of REM in plant immune signaling. Further protein-protein interaction studies reveal novel REM binding partners with a possible role in plant immune signaling. Thus, REM might act as an assembly hub for an immune signaling complex targeted by HopZ1a. Taken together, this is the first report describing that a REM protein is targeted by a bacterial effector. How HopZ1a might mechanistically manipulate the plant immune system through interfering with REM function will be discussed.}, language = {en} } @misc{AissenCrewett1998, author = {Aissen-Crewett, Meike}, title = {Prolog zu multiplen Intelligenz : Pluralit{\"a}t der Vernunft ; zu Wolfgang Welschs Konzept der pluralen und transversalen Vernunft}, year = {1998}, language = {de} } @misc{AissenCrewett1998, author = {Aissen-Crewett, Meike}, title = {Der Ausbruch aus dem Ghetto der rational-logischen Intelligenz : Howard Gardners {\"O}ffnung zur Vielfalt der Intelligenzen ; Chance und Herausforderung f{\"u}r die P{\"a}dagogik}, year = {1998}, language = {de} } @misc{AissenCrewett1998, author = {Aissen-Crewett, Meike}, title = {{\"A}sthetische Intelligenz : was ist sie und was bedeutet sie f{\"u}r den natur- und naturwissenschaftsbezogenen Unterricht?}, year = {1998}, language = {de} }
