Backward Reachability Analysis of Colored Petri Nets

This paper deals with a formal method for the study of the backward reachability analysis applied on Colored Petri Nets (CPN). The proposed method proceeds in two steps : 1) it translates CPN to terms of the Multiplicative Intuitionistic Linear Logic (MILL); 2) it proves sequents by constructing proof trees. The translation from CPN to MILL must respect some properties such as the semantic associated to tokens. That is why, the First-Order MILL (MILL1) is used for translation. The reachability between two markings, the initial marking and the final marking, is expressed by a sequent which can be proven (if the initial marking is backward-reachable from the final one) using first-order terms unification and/or marking enhancement.
Computational fact-checking: a content management perspective

Data journalism designates journalistic work inspired by digital data sources. A particularly popular and active area of data journalism is concerned with fact-checking. The term was born in the journalist community and referred the process of verifying and ensuring the accuracy of published media content; since 2012, however, it has increasingly focused on the analysis of politics, economy, science, and news content shared in any form, but first and foremost on the Web (social and otherwise). These trends have been noticed by computer scientists working in the industry and academia. Thus, a very lively area of digital content management research has taken up these problems and works to propose foundations (models), algorithms, and implement them through concrete tools. Our tutorial: (i) Outlines the current state of affairs in the area of digital (or computational) fact-checking in newsrooms, by journalists, NGO workers, scientists and IT companies; (ii) Shows which areas of digital content management research, in particular those relying on the Web, can be leveraged to help fact-checking, and gives a comprehensive survey of efforts in this area; (iii) Highlights ongoing trends, unsolved problems, and areas where we envision future scientific and practical advances.

Effects of stocking density and photoperiod manipulation in relation to estradiol profile to enhance spawning activity in female Nile tilapia

This study investigated the effects of stocking density and photoperiod manipulation in relation to plasma estradiol-17? (E2) profile to enhance spawning activity in female Nile tilapia (Oreochromis niloticus) using F1 clonal crosses. The fish were divided into experimental and control groups and subjected to a combination of stocking density and photoperiod treatments (40kg/m3;6L:18D, 40kg/m3;12L:12D and transferred into single compartments at 12L:12D; 14kg/m3;12L:12D), respectively. Blood samples were taken by caudal puncture from experimental fish for estradiol profile analysis. Results showed that experimental fish exhibited significantly higher number of spawns per day, total fecundity and relative fecundity (p
The Stimulation and Depression of Reticulo-endothelial Phagocytic Function by Simple Lipids.

THE cells of the reticulo-endothelial system (RES) in contact with the blood stream possess a singular degree of autonomy and the physiological factors concerned in the regulation of their activity remain mostly unknown. It is well recognised that RES phagocytic function may be altered by various colloids, certain infections and lipopolysaccharide from Gram negative bacilli (Biozzi, Halpern, Benacerraf and Stiffel, 1957). It must be emphasized that these substances are derived from widely different sources, are often chemically complex and are not physiological components of the organism. Accordingly it is of interest that certain simple molecules of known constitution can cause profound and opposing changes in phagocytic activity. This communication reports the effect of glyceryl and ethyl esters of fatty acids on phagocytic function as measured by the clearance of injected colloidal carbon from the blood stream.
INVESTIGATION OF CYCLODEXTRIN BASED NANOSPONGES COMPLEXES WITH ANGIOTENSIN I CONVERTING ENZYME INHIBITORS ( ENALAPRIL , CAPTOPRIL , CILAZAPRIL )

Cyclodextrin based nanosponges are cross-linked polymeric networks formed by cyclodextrins and cyclodextrin derivatives; they are obtained by reacting cyclodextrin with a cross-linker agent such as carbonyldiimidazole, organic carbonates or (±) epichlorohydrin) and have many important applications as drug delivery systems or for pollutants removal in environmental issues. Several β-CD, sulfobutylether-β-CD and hydroxypropyl-β-CD nanosponges were prepared using epichlorohydrin as cross-linker. After liophylization, the polymers were purified and characterized by FT-IR and H NMR, respectively. The complexing properties of the CD polymers were investigated against enalapril, captopril and cilazapril (effective drugs for controling blood pressure, congestive heart failure, and prevention of stroke and hypertension acting as angiotensin converting enzyme -ACEinhibitors), in order to improve their stability and bioavailability and to overcome the possible drug-excipient interactions. The drug-nanosponge complexes prepared through liophylization were characterized by FT-IR and HNMR; the phase-solubility diagrams, the solubility profile and the loading capacity of the cyclodextrin polymers were also determined.
Analyzing AWS Spot Instance Pricing

Many cloud computing vendors offer a preemptible class of service for rented virtual machines. In November 2017, Amazon.com changed the pricing mechanism for its preemptible "spot instances" so that prices would change more "smoothly. " This paper analyzes the effect of this change on spot instance prices. It examines the prices immediately before and after the mechanism change to determine the extent to which prices themselves changed. It then compares the 90-day period immediately after the change in mechanism to the next 90-day period. Finally, it compares the two most recent 90-day periods (ending on October 15, 2018). Our results indicate that in addition to smoothing prices, the mechanism change introduced generally higher prices which is a trend that continues.
HapTick : Highly Accessible Gestures Using Tactile Cues

While high-resolution and miniature gesture sensing technology has been widely explored, the interaction space is still limited due to the nature of low-resolution human proprioceptive sense. To better utilize the control space, we introduce HapTick, a method that discretizes one-dimensional swiping gestures with prompt tactile cues. By counting the tactile stimuli on the path of swiping, the user could effectively select numeric target in one typical swipe. We first derived the effective interval between modes. The results showed that with more-than-3mm distance between ticks, the overall accuracy of 95% can be achieved. In the second study, we compared two methods for selecting a digit ranging from 1 to 10. While there’s no differences in completion time between multiple swiping selection and HapTick (3.2 sec vs 3.4 sec), HapTick outperforms in both physical demands (5 vs. 2*) and overall preference (2.41 vs. 4.41*). Lastly, we confirm the feasibility of applying HapTick to other interaction domain, e.g., on-screen swiping, in-air gesture and input on 2D surface, in an explorative study. Two application scenarios were also proposed based on our findings. ACM Classification
The trophic structure of tropical ant-plant-herbivore interactions: community consequences and coevolutionary dynamics.

Introduction The first part of this paper examines the consequences of an interlocking set of mutualisms, involving ants, plants, bacteria and phloem-feeding insects, for the structure and functioning of herbivore-based food webs in tropical communities. This part draws heavily from important recent work by Davidson and colleagues (Davidson 1997; Davidson et al. 2003) and extends their discussion of community-level implications of their findings. The second part explores how trophic interactions evolve when coevolution produces specialized symbiotic ant–plant mutualisms, and is based largely on our own work on interactions between ants and Leonardoxa myrmecophytes of African rainforests. The paper complements a recent general review of ant–plant protection mutualisms (Heil & McKey 2003).
Casimir effect for a stack of conductive planes

The Casimir interaction in a stack of equally spaced infinitely thin layers is investigated within the zero-frequency mode summation method. The response properties are considered to be described by a constant conductivity or by a Drude-Lorentz model with a finite set of oscillators consistent with the optical characteristics for graphite. It is found that the asymptotic distance dependence is affected significantly by the specific response. While the energy is $\sim 1/d^3$ for the constant conductivity model, the energy exhibits fractional dependence $\sim 1/d^{5/2}$ for the Drude-Lorentz description. The Casimir force on a plane is also strongly dependent upon the particular plane location in the stack. Furthermore, the calculated Casimir energy within the Drude-Lorentz model yields results in good agreement with measured cohesion energy in graphite.
2 Generic Framework for Crowdsensing Based Smart City Applications

The rapid technological development and the introduction of smart services make it possible for modern cities to offer an enhanced perception of city life for their inhabitants. For instance, a smart timetable service of the city’s public transportation lines updated in real-time can decrease unnecessary waiting times at stops and increase the efficiency of travel planning. However, the implementation of such a service in a traditional way requires the deployment and maintenance of some costly sensing and tracking infrastructure. Fortunately, mobile crowdsensing, when the crowd of passengers and their mobile devices are used to gather data, can be a viable and almost free of charge alternative for implementing sensing based smart city services. In this chapter, we put the emphasis on the introduction of a crowdsensing based smart timetable service, which has been developed as a prototype smart city application. The front-end interface of this service is called TrafficInfo. It is a simple and easy-to-use Android application which visualizes public transport information of the given city on Google Maps in real-time. The live updates of transport schedule information rely on the automatic stop event detection of public transport vehicles. TrafficInfo is built upon an Extensible Messaging and Presence Protocol (XMPP) based communication framework which was designed to facilitate the development of crowd assisted smart city applications. The chapter introduces this generic framework shortly, then describes the prototype smart timetable service.

A role of FLT 3 gene mutation in acute myeloid leukemia patients from Pakistan

Natural hematopoises has been described by the development of blood cells which in turn is regulated by need of the body. If these regulatory systems were disrupted, the production of these cells becomes excessive. The changes mostly occur in the hematopoietic stem cells (HSC) which normally go on to form blood cells, but defects in the hematopoietic stem cells cause an increase circulation of leukemic cells in the body with threatening effects. The incidences of acute myeloid leukemia (AML) in world are about 0.01% and in Pakistan it is more common in Punjab. Commonly, patients with AML were diagnosed by having genetic alterations. Whereas approximately 30% of AML patients have Fms-like tyrosine kinase 3 (FLT3) gene alterations. AML spread very quickly and if not treated it becomes fatal in the short period of time. Through the understanding of molecular biology of cancer and identification of mutations in AML the advancement in the targeted therapeutics has increased and more better drugs, that target products of protein molecules of mutated genes associated with various cancers, are thus being practiced.

Features of Cytokine Profile in Patients with Progressive TB-Induced Pulmonary Fibrosis Characterized by Various Intensities of Pulmonary Destructive Changes Production of pro- and anti-inflammatory cytokines (IFN-γ, IL-2, TNF-α, IL-8, IL-4, IL-10) in patients with pulmonary TB infection with various spread and severity of the process were investigated in in vitro PPD- and PHA-stimulated peripheral blood mononuclear cells (PBMCs). It was demonstrated that each type of MDR-TB lung fibrosis is determined by specific traits of a multilevel cytokine network functioning according to activity of cytokine-producing cells.
From Tag to Protect: A Tag-Driven Policy Recommender System for Image Sharing

Sharing images on social network sites has become a part of daily routine for more and more online users. However, in face of the considerable amount of images shared online, it is not a trivial task for a person to manually configure proper privacy settings for each of the images that he/she uploaded. The lack of proper privacy protection during image sharing could raise many potential privacy breaches of people's private lives that they are not aware of. In this work, we propose a privacy setting recommender system to help people effortlessly set up the privacy settings for their online images. The key idea is developed based on our finding that there are certain correlations between a number of generic patterns of image privacy settings and image tags, regardless of the image owners' individual privacy bias and levels of awareness. We propose a multi-pronged mechanism that carefully analyzes tags' semantics and co-presence to derive a set of suitable privacy settings for a newly uploaded image. Our system is also capable of dealing with cold-start problem when there are very few image tags available. We have conducted extensive experimental studies and the results demonstrate the effectiveness of our approach in terms of the policy recommendation accuracy.
Telepresence robots for medical and homecare applications

Over the past few decades, robotics has made tremendous progress in saving, protecting, and improving human lives, and is now adopted across a broad range of applications in medicine and homecare services. While technologies are developed at a rapid pace, people are expecting robots to be part of their lives in a more natural way. Among the wide variety of robots, telepresence robots, which allow the user to experience the virtual presence in another place, offer the potential to meet this rising demand better and is thus of great concern. This section will explore the up-to-date research findings and industry practices in telepresence robots for medical and homecare applications. Moreover, the key contributing factors to the success of telepresence robots will be discussed as well to address the future trends and opportunities.
Dictionary learning based fingerprinting for indoor localization

Indoor localization is often challenging due to the non-availability of GPS signals. Recently, various radio frequency fingerprinting techniques have been proposed to identify indoor locations using simply received signal strength (RSS) measurements. In general however, RSS measurements are time-varying and are difficult to model for complex environments. This paper proposes the use of dictionary learning (DL) to generate high quality fingerprints that depend also on the channel characteristics for each location. An enhanced DL algorithm is proposed that utilizes prior information about the channel distribution, and can generate the fingerprints in an online fashion. Simulation results demonstrate the efficacy of the proposed approach.
Phase equilibria by simulation in the Gibbs ensemble

The Gibbs-ensemble Monte Carlo simulation methodology for phase equilibrium calculations proposed by Panagiotopoulos [1] is generalized and applied to mixture and membrane equilibria. An alternative derivation of the Gibbs simulation criteria based on the limiting distributions for the appropriate statistical mechanical ensembles is presented. The method is then generalized for the calculation of phase equilibria of mixtures by simulation in a constantpressure Gibbs ensemble and the calculation of equilibria across semipermeable membranes with an imposed osmotic pressure difference. The method is used to calculate phase equilibria for binary mixtures of Lennard-Jones molecules. Good agreement is found with published results obtained using other simulation techniques. The computer time required for the Gibbs method is only a small fraction of the corresponding requirement for previously available simulation techniques. Calculations for simple osmotic systems are performed for the first time by simulation, .
Quality of Accounting Information and Financial Performance of Uganda's Public Sector

The study aimed at establishing the relationship between the quality of accounting information and financial performance of the public sector in Uganda. Despite the continuous production of accounting information as required by the Government Financial and Accounting Regulations and adoption of IPSAS, there is widespread reported misuse of resources and poor accountability. The central question of the study was whether quality of accounting information had any impact on the financial performance of the public sector. The researcher adopted a blend of cross-sectional and descriptive research designs and stratified random sampling. The primary respondents were the City division who participate in the allocation and control of financial resources and act as watchdogs of the financial management process of the divisions on behalf of their electorates. A research questionnaire that addressed the quality attributes of accounting information was tested for validity and reliability and administered to collect primary data. Audited financial performance data was also analyzed. It was discovered that Relevance, reliability, understandability, accuracy and timeliness were true measures of the quality of accounting information through factor analysis. T-tests and ratio analysis revealed that the reporting units where financial accounting information was perceived of high quality reflected higher levels of financial performance. Regression and correlation analyses revealed a significant positive relationship with approximately 58% of the financial performance levels attributed to financial information quality. It is therefore desirable that public sector entities employ highly skilled professionals that adhere to reporting requirements of the legal and regulatory framework.
