    Linear Network Coding for Two-Unicast-ZZ Networks: A Commutative Algebraic Perspective and Fundamental Limits

    Full text link
    We consider a two-unicast-ZZ network over a directed acyclic graph of unit capacitated edges; the two-unicast-ZZ network is a special case of two-unicast networks where one of the destinations has apriori side information of the unwanted (interfering) message. In this paper, we settle open questions on the limits of network coding for two-unicast-ZZ networks by showing that the generalized network sharing bound is not tight, vector linear codes outperform scalar linear codes, and non-linear codes outperform linear codes in general. We also develop a commutative algebraic approach to deriving linear network coding achievability results, and demonstrate our approach by providing an alternate proof to the previous results of C. Wang et. al., I. Wang et. al. and Shenvi et. al. regarding feasibility of rate (1,1)(1,1) in the network.Comment: A short version of this paper is published in the Proceedings of The IEEE International Symposium on Information Theory (ISIT), June 201

    Current high-throughput gene expression experiments have a straightforward design of examining the gene expression of one group or condition relative to that of another. The data is typically analyzed as if they represent strictly intracellular events, and often treats genes as coming from a homogeneous population. Although intracellular events are crucial to nearly all biological processes, cell-cell interactions are often just as important, especially when gene expression data is generated from heterogeneous cell populations, such as from whole tissues. Cell-cell molecular interactions are generally lost in the available analytical procedures and as a result, are not examined experimentally, at least not accurately or with efficiency. Most importantly, this imposes major limitations when studying gene expression changes in multiple samples that interact with one another. In order to addresses the limitations of current techniques, we have developed a novel systems-based approach that expands the traditional analysis of gene expression in two stages. This includes a novel sequence-based meta-analytic tool, AbsIDconvert, that allows for conversion of annotated features using an interval tree for storing and querying absolute genomic coordinates for comparison of multi-scale macro-molecule identifiers across platforms and/or organisms. In addition, a systems-based heuristic algorithm is developed to find intercellular interactions between two sets of genes, potentially from different tissues by utilizing location information of each gene along with the information available in the secondary databases in the form of interactions, pathways and signaling. AbsIDconvert is shown to provide a high accuracy in identifier conversion as compared to other available methodologies (typically at an average rate of 84%) while maintaining a higher efficiency (O(n*log(n)). Our intercellular interaction approach and underlying visualization shows promise in allowing researchers to uncover novel signaling pathways in an intercellular fashion that to this point has not been possible

    Salted Inference: Enhancing Privacy while Maintaining Efficiency of Split Inference in Mobile Computing

    Full text link
    In split inference, a deep neural network (DNN) is partitioned to run the early part of the DNN at the edge and the later part of the DNN in the cloud. This meets two key requirements for on-device machine learning: input privacy and computation efficiency. Still, an open question in split inference is output privacy, given that the outputs of the DNN are observable in the cloud. While encrypted computing can protect output privacy too, homomorphic encryption requires substantial computation and communication resources from both edge and cloud devices. In this paper, we introduce Salted DNNs: a novel approach that enables clients at the edge, who run the early part of the DNN, to control the semantic interpretation of the DNN's outputs at inference time. Our proposed Salted DNNs maintain classification accuracy and computation efficiency very close to the standard DNN counterparts. Experimental evaluations conducted on both images and wearable sensor data demonstrate that Salted DNNs attain classification accuracy very close to standard DNNs, particularly when the Salted Layer is positioned within the early part to meet the requirements of split inference. Our approach is general and can be applied to various types of DNNs. As a benchmark for future studies, we open-source our code.Comment: To be appeared in the 25th International Workshop on Mobile Computing Systems and Applications (HotMobile 2024

    Comparison of Compressive Strength and Flexural Capacity between Engineered Cementitious Composites (Bendable Concrete) and Conventional Concrete used in Bangladesh

    The Engineered Cementitious Composites (ECC) is made of the same ingredients as in regular concrete. The coarse aggregate is replaced with tiny Polyvinyl Alcohol fibres. This structure offers maximum flexibility and it is expected to cost less. It looks exactly like normal concrete, but under excessive strain, the ECC concrete allows, the specially coated network of fibre in the cement to slide within the cement, thus avoiding the inflexibility that causes brittleness and breakage. As this is a special type of concrete there are no defined codes for it, thus for these reasons, the parameters needed are to be obtained using trial and error method. During the composite preparation, sieve analysis was carried out. Composites were reinforced with Polyvinyl Alcohol (PVA) at the following ratios: 0 % (control), 0.5 %, 1 % and 1.5 %. The cylindrical specimens were subjected to compression and the slab specimens were subjected to flexural test using a Universal Testing Machine, while acquiring data with GOM Correlation Software. Test results reveal that fibre ratio 1% is most acceptable for attaining best compressive strength along with high flexural value. Even though 1% fibre content concrete in the flexural strength test showed 33% less strength of what 1.5% fibre content concrete gained, in the long run, for having the highest compressive strength value (almost 62% more than of 0% fibre content concrete and 15% more than of 1.5% fibre content concrete), 1% fibre content concrete is most suited for constructions

    The Status and dignity of Women in Islam and Hinduism

    The heavenly religions have spoken much about the creation of man and his place in the world of creation. The position of women in these religions, known as the revelation religions, is very high. In the ancient Hindus, woman was not dignified and regarded as much as men, although in the Upanishads the woman was intrinsically valued, and man and woman are half halves that complement each other. There is no legal difference between men and women in India today, and women can engage in political, economic, and cultural activities as men. In Hinduism, woman holds a high position as a mother, from the point of view of Hinduism, the ideal woman is a woman who loves her husband and provides his with comfort. But the Hindu girl is far less valuable than the Hindu boy, and many Hindus do not generally favor the girl child. From the Islamic point of view, men and women have equal value in terms of humanity, and no one has superiority over others in their humanity. But this does not mean that any physical and mental differences between the two are denied. The holy religion of Islam considers women the first and foremost task of marrying and raising children, by assigning specific duties to women that are commensurate with their type of creation, but at the same time permits women to adhere to the principles of a Muslim woman participate in the community and engage in social and economic activities

    Objectives: This study evaluated the association between pus cells and semen parameters in infertile Pakistani males. Methods: A cross-sectional descriptive study was carried out in the Department of Reproductive Physiology/Health, National Institute of Health, Islamabad, Pakistan, from 2004 to 2009. A total of 1,521 subjects were analysed, along with 97 proven fathers as controls. Results: The mean of pus cells was 7.43 ± 0.43, 4.35 ± 0.34, and 4.26 ± 0.17 per high field in teratozoospermic, oligoasthenozoospermic, and asthenozoospermic groups, respectively, while it was 3.25 ± 0.26, 3.10 ± 0.19, and 2.98 ± 0.04 per high field in azoospermic, oligozoospermic and the proven father groups, respectively. The fewest pus cells were observed among proven fathers, which varied non-significantly (P >0.05) with all cases, except with teratozoospermic, oligozoospermic, and oligoasthenozoospermic cases. Pus cells showed an inverse relationship to sperm motility and count, except in azoospemia cases. Similarly, the fewest pus cells were observed among groups where normal forms where significantly more frequent (P <0.05). More pus cells were observed in cases where motility, and concentration or morphology was compromised. Similarly, low pus cell counts were seen in cases where sperm had the fewest head and neck defects. All kinds of sperm defects varied non-significantly (P >0.05) between proven fathers and normal concentration cases. Conclusion: High pus cell counts were observed in various subclasses of infertile patients. Ignorance of this pyospermic factor will make pyospermic patients to be misdiagnosed as normozoospermic. Therefore, the presence of pyospermia must be considered by physicians as a male infertility factor
