TL;DR: In this article, a survey and experimental findings in the literature on attitudes to income inequality are reviewed and classified into two broad types of individual attitudes toward the income distribution in a society: the normative and the comparative view.
Abstract: We review the survey and experimental findings in the literature on attitudes to income inequality. We interpret the latter as any disparity in incomes between individuals. We classify these findings into two broad types of individual attitudes toward the income distribution in a society: the normative and the comparative view. The first can be thought of as the individual's disinterested evaluation of income inequality; on the contrary, the second view reflects self-interest, as individuals’ inequality attitudes depend not only on how much income they receive but also on how much they receive compared to others. We conclude with a number of extensions, outstanding issues, and suggestions for future research.

TL;DR: FlowDroid is presented, a novel and highly precise taint analysis for Android applications that achieves 93% recall and 86% precision, greatly outperforming the commercial tools AppScan Source and Fortify SCA.
Abstract: Today’s smart phones are a ubiquitous source of private and confidential data. At the same time, smartphone users are plagued by malicious apps that exploit their given privileges to steal such sensitive data, or to track users without their consent or even the users noticing. Dynamic program analyses fail to discover such malicious activity because apps have learned to recognize the analyses as they execute. In this work we present FlowDroid, a novel and highly precise taint analysis for Android applications. A precise model of Android’s lifecycle allows the analysis to properly handle callbacks, while context, flow, field and objectsensitivity allows the analysis to track taints with a degree of precision unheard of from previous Android analyses. We also propose DroidBench, an open test suite for evaluating the e↵ectiveness and accuracy of taint-analysis tools specifically for Android apps. As we show through a set of experiments using SecuriBench Micro, DroidBench and a set of well-known Android test applications, our approach finds a very high fraction of data leaks while keeping the rate of false positives low. On DroidBench, our approach achieves 93% recall and 86% precision, greatly outperforming the commercial tools AppScan Source and Fortify SCA.

TL;DR: This paper presents an efficient search tool for finding differential characteristics both in the state and in the key and designs the best related-key and chosen key attacks on AES, byte-Camellia, Khazad, FOX, and Anubis.
Abstract: While differential behavior of modern ciphers in a single secret key scenario is relatively well understood, and simple techniques for computation of security lower bounds are readily available, the security of modern block ciphers against related-key attacks is still very ad hoc. In this paper we make a first step towards provable security of block ciphers against related-key attacks by presenting an efficient search tool for finding differential characteristics both in the state and in the key (note that due to similarities between block ciphers and hash functions such tool will be useful in analysis of hash functions as well). We use this tool to search for the best possible (in terms of the number of rounds) related-key differential characteristics in AES, byte-Camellia, Khazad, FOX, and Anubis. We show the best related-key differential characteristics for 5, 11, and 14 rounds of AES-128, AES-192, and AES-256 respectively. We use the optimal differential characteristics to design the best related-key and chosen key attacks on AES-128 (7 out of 10 rounds), AES-192 (full 12 rounds), byte-Camellia (full 18 rounds) and Khazad (7 and 8 out of 8 rounds). We also show that ciphers FOX and Anubis have no related-key attacks on more than 4-5 rounds.

TL;DR: Studies on the effects of exogenous arachidonic acid demonstrated that the postulated airway epithelium-dependent relaxant factor released by an intact tracheal strip relaxes an adjacent epithelia-free strip in the same organ bath.
Abstract: Exogenous arachidonic acid (10(-8) to 10(-4) M) contracted epithelium-free guinea pig tracheal strips. Intact tracheal strips were contracted slightly by low concentrations of arachidonic acid (10(-8) to 10(-5) M), but higher concentrations relaxed them. In contrast, when tracheal strips were precontracted with histamine or carbachol, exogenous arachidonic acid had no effect on epithelium-free preparations but induced concentration-dependent (10(-8) to 10(-4) M) relaxation of intact tracheal strips. The effects of arachidonic acid both in epithelium-free and epithelium-containing trachea were blocked by either indomethacin (10(-6) M) or aspirin (10(-4) M). Studies on the effects of exogenous arachidonic acid, performed with a "sandwich protocol," demonstrated that the postulated airway epithelium-dependent relaxant factor released by an intact tracheal strip relaxes an adjacent epithelium-free strip in the same organ bath. This relaxation is antagonized by indomethacin suggesting the involvement of a cyclooxygenase product in this phenomenon. Comparison of concentration-response curves for contractile agonists in epithelium-free preparations and in one containing epithelium suggests the mobilization of airway epithelium-dependent relaxant factor by histamine but not by carbachol. The effects of cyclooxygenase and lipoxygenase inhibitors indicated that both relaxant and contractile arachidonic acid metabolites are generated by epithelial and nonepithelial cells alike in response to contractile agonists.

TL;DR: The importance of integrating metabolic networks with regulatory information is emphasized—an area which is expected to become increasingly important for metabolic engineering—and recent developments in the field of metabolic and regulatory integration are presented.
Abstract: We focus on the application of constraint-based methodologies and, more specifically, flux balance analysis in the field of metabolic engineering, and enumerate recent developments and successes of the field. We also review computational frameworks that have been developed with the express purpose of automatically selecting optimal gene deletions for achieving improved production of a chemical of interest. The application of flux balance analysis methods in rational metabolic engineering requires a metabolic network reconstruction and a corresponding in silico metabolic model for the microorganism in question. For this reason, we additionally present a brief overview of automated reconstruction techniques. Finally, we emphasize the importance of integrating metabolic networks with regulatory information—an area which we expect will become increasingly important for metabolic engineering—and present recent developments in the field of metabolic and regulatory integration.
