Reference-guided de novo assembly approach improves genome reconstruction for related species.

The development of next-generation sequencing has made it possible to sequence whole genomes at a relatively low cost. However, de novo genome assemblies remain challenging due to short read length, missing data, repetitive regions, polymorphisms and sequencing errors. As more and more genomes are sequenced, reference-guided assembly approaches can be used to assist the assembly process. However, previous methods mostly focused on the assembly of other genotypes within the same species. We adapted and extended a reference-guided de novo assembly approach, which enables the usage of a related reference sequence to guide the genome assembly. In order to compare and evaluate de novo and our reference-guided de novo assembly approaches, we used a simulated data set of a repetitive and heterozygotic plant genome. The extended reference-guided de novo assembly approach almost always outperforms the corresponding de novo assembly program even when a reference of a different species is used. Similar improvements can be observed in high and low coverage situations. In addition, we show that a single evaluation metric, like the widely used N50 length, is not enough to properly rate assemblies as it not always points to the best assembly evaluated with other criteria. Therefore, we used the summed z-scores of 36 different statistics to evaluate the assemblies. The combination of reference mapping and de novo assembly provides a powerful tool to improve genome reconstruction by integrating information of a related genome. Our extension of the reference-guided de novo assembly approach enables the application of this strategy not only within but also between related species. Finally, the evaluation of genome assemblies is often not straight forward, as the truth is not known. Thus one should always use a combination of evaluation metrics, which not only try to assess the continuity but also the accuracy of an assembly

Performance Evaluation of Centralized In-Network Caching and Content Visibility in Information Centric Network over SDN/OpenFlow

Performance is the main issue that we must consider as the key point in order to design Information Centric Network architecture (ICN). Cooperative in-network caching and ability of network’s nodes to see the contents in network will improve performance of ICN. In centralized network, the controller plays very important role in order to enable ICN nodes to do cooperative caching. Also, it has ability to see contents partially or globally according to our configuration. This paper aims to observe and compare the performance of ICN when we apply different levels of cooperative in-network caching and content visibility based on centralized control by using SDN/OpenFlow concept. We will evaluate performance of ICN by using three mechanisms; firstly, non-cooperative in-network caching with individual visibility; secondly, path cooperative in-network caching with path content visibility; and finally, global cooperative in-network caching with global content visibility. Our emulation result shows that global cooperative in-network caching with global content visibility mechanism gives better performance for ICN in terms of average number of hops to reach the content and number of requests hit server

OrthoGAN: Multifaceted Semantics for Disentangled Face Editing

This paper describes a new technique for finding disentangled semantic directions in the latent space of StyleGAN. OrthoGAN identifies meaningful orthogonal subspaces that allow editing of one human face attribute, while minimizing undesired changes in other attributes. Our model is capable of editing a single attribute in multiple directions. Resulting in a range of possible generated images. We compare our scheme with three state-of-the-art models and show that our method outperforms them in terms of face editing and disentanglement capabilities. Additionally, we suggest quantitative measures for evaluating attribute separation and disentanglement, and exhibit the superiority of our model with respect to those measures

THE HEARTLAND THEORY OF SIR HALFORD JOHN MACKINDER: JUSTIFICATION OF FOREIGN POLICY OF THE UNITED STATES AND RUSSIA IN CENTRAL ASIA

The paper examines the foreign policy of the United States and Russia towards Central Asia by reviewing selective foreign policy discourses in the context of the Heartland theory. In effect, the central formulation of the study rests on this research question: to what extent is the Heartland theory influential in the foreign policy of the United States and Russia? The analysis is therefore organized by first conducting a comparative/contrast approach of the USA and Russian policies via each other. The analysis seeks to suggest and/or establish some relationship between the predictions of the theory and current foreign policy relations. The study has reached to a conclusion that literature around the United States and Russia is indicative to the relevancy of Heartland theory

DeepShadow: Neural Shape from Shadow

This paper presents DeepShadow, a one-shot method for recovering the depth map and surface normals from photometric stereo shadow maps. Previous works that try to recover the surface normals from photometric stereo images treat cast shadows as a disturbance. We show that the self and cast shadows not only do not disturb 3D reconstruction, but can be used alone, as a strong learning signal, to recover the depth map and surface normals. We demonstrate that 3D reconstruction from shadows can even outperform shape-from-shading in certain cases. To the best of our knowledge, our method is the first to reconstruct 3D shape-from-shadows using neural networks. The method does not require any pre-training or expensive labeled data, and is optimized during inference time
