Economically Optimal MS Association for Multimedia Content Delivery in Cache-Enabled Heterogeneous Cloud Radio Access Networks

In cache-enabled heterogeneous cloud radio access networks (HC-RANs), mobile station (MS) association for multimedia content delivery should consider both the content caching location and the wireless channel quality. This paper studies economically optimal MS association to tradeoff the cache-hit ratio and the ratio of MSs with satisfied quality of service (QoS). When the associated enhanced remote radio unit (eRRU) stores the requesting content, the content can be fetched directly from the local cache. Otherwise, fronthaul has to be used to fetch the content. The use of fronthaul resource and cache is treated as costs, and payments of QoS-satisfied MSs are treated as incomes. Thus, the economic MS association is formulated as an optimization problem to maximize the system utility, i.e., total profit of the network operator, which is defined as the difference between incomes and costs. A belief propagation-based method is employed to solve the problem on a developed factor graph. Simulation results show that the proposed economically optimal MS association achieves much higher profit than the existing schemes and works well in the network with various loads. Moreover, the profit of the proposed scheme can be improved with inter-cell interference coordination. For the case with extremely skewed content popularity, the proposed scheme can avoid MS overloading at eRRUs storing most popular multimedia contents. Furthermore, it can support more MSs with satisfied QoS, which leads to a higher profit.
Macroeconomics Determinants of Saudi Arabia’s Inflation 2000-2016: Evidence and Analysis

This study deals with rising prices in Saudi Arabia from 2000 to 2016. Inflation in an open economy can be influenced by both domestic and global factors. The aim of the paper is to examine macroeconomics determinants of inflation in Saudi Arabia. The study has employed regression model, in which the dependent variable is inflation (CPI) and independent variables are money supply, fixed exchange rate against U.S dollar, oil prices, import value, export value and unemployment. Empirical result shown that Money supply, fixed exchange rate against U.S dollar, import value, export value, and oil prices have statistical significance with inflation in Saudi Arabia except unemployment that does not directly predict inflation rates in Saudi Arabia. It has been concluded that effect of domestic factors on Saudi inflation eroded over the last 13 years as Saudi inflation become more globalized.
WARDOG: Awareness Detection Watchdog for Botnet Infection on the Host Device

Botnets constitute nowadays one of the most dangerous security threats worldwide. High volumes of infected machines are controlled by a malicious entity and perform coordinated cyber-attacks. The problem will become even worse in the era of the Internet of Things (IoT) as the number of insecure devices is going to be exponentially increased. This paper presents WARDOG – an awareness and digital forensic system that informs the end-user of the botnet's infection, exposes the botnet infrastructure, and captures verifiable data that can be utilized in a court of law. The responsible authority gathers all information and automatically generates a unitary documentation for the case. The document contains undisputed forensic information, tracking all involved parties and their role in the attack. The deployed security mechanisms and the overall administration setting ensures non-repudiation of performed actions and enforces accountability. The provided properties are verified through theoretic analysis. In simulated environment, the effectiveness of the proposed solution, in mitigating the botnet operations, is also tested against real attack strategies that have been captured by the FORTHcert honeypots, overcoming state-of-the-art solutions. Moreover, a preliminary version is implemented in real computers and IoT devices, highlighting the low computational/communicational overheads of WARDOG in the field.
Household Level Determinants of Agroforestry Practices Adoption in Rural Ethiopia

ABSTRACT Agroforestry is increasingly promoted as an economically and environmentally sustainable land use system. Understanding factors affecting smallholder farmers’ decision to adopt agroforestry technologies and intensity of adoption is thus considered critical for the development of agroforestry. This research attempts to analyze and understand why agroforestry technologies are not being taken up more by examining household level factors that could influence the adoption of agroforestry technologies. We estimate Heckman selection model using household level data collected from different regions of rural Ethiopia. Our findings show that the age of the household head, land size, tenure insecurity, and proximity to towns have a significant effect on the probability of adopting. They also show that, once adoption decision had been taken, the area devoted to agroforestry technologies is influenced by household characteristics such as gender of the household head, land size, and proximity to towns. We also identify important measures that could help promoting agroforestry technologies in rural Ethiopia. Our findings may also provide scientific evidence for other similar countries whose livelihood depends mainly on agriculture and natural resources such as forests.
Broad dengue neutralization in mosquitoes expressing an engineered antibody

With dengue virus (DENV) becoming endemic in tropical and subtropical regions worldwide, there is a pressing global demand for effective strategies to control the mosquitoes that spread this disease. Recent advances in genetic engineering technologies have made it possible to create mosquitoes with reduced vector competence, limiting their ability to acquire and transmit pathogens. Here we describe the development of Aedes aegypti mosquitoes synthetically engineered to impede vector competence to DENV. These mosquitoes express a gene encoding an engineered single-chain variable fragment derived from a broadly neutralizing DENV human monoclonal antibody and have significantly reduced viral infection, dissemination, and transmission rates for all four major antigenically distinct DENV serotypes. Importantly, this is the first engineered approach that targets all DENV serotypes, which is crucial for effective disease suppression. These results provide a compelling route for developing effective genetic-based DENV control strategies, which could be extended to curtail other arboviruses. Significance Statement Here we describe the development of Ae. aegypti mosquitoes synthetically engineered to impede vector competence to multiple serotypes of DENV. Given the global significance of DENV, these mosquitoes may be used to curtail Dengue transmission by this potent vector.
Seedling Selection Using Molecular Approach for Ex Situ Conservation of Critically Endangered Tree Species (Vatica bantamensis (Hassk.) Benth. & Hook. ex Miq.) in Java, Indonesia

Ex situ conservation is an important complementary strategy for in situ to conserve endangered plant species. However, the limited areas designated for ex situ conservation such as in botanic gardens have become a great challenge for conservation practitioners and scientists attempting to optimally conserve the genetic diversity of targeted plant species. Our study aimed to assess genetic diversity and structure of wild seedlings of Vatica bantamensis, an endemic and critically endangered dipterocarp from Java (Indonesia). We also estimated genetic differentiation between the wild seedlings and existing ex situ collection and evaluated the genetic diversity preserved in the ex situ collection. Our analysis, using 730 single-nucleotide polymorphisms loci, showed that wild seedlings exhibited higher genetic diversity than the ex situ collection (nucleotide diversity, µ = 0.26 and 0.16, respectively). Significant genetic differentiation was also detected (FST = 0.32) between wild seedlings and ex situ collection. Furthermore, we found high kinship within the ex situ collection suggesting low genetic diversity since the founding collection. We also detected three distinct genetic clusters from all samples combined (analysis of molecular variance, ϕ = 0.48, p < .001), with two clusters present in the wild seedlings that were not represented in the ex situ collection. We recommend that supplementary collections from the two newly identified genetic clusters in the wild seedlings should be incorporated to increase genetic diversity in the ex situ collection. Furthermore, our study demonstrated that understanding the population genetics of targeted endangered species provides better results for ex situ conservation strategies.
Respiratory Fungal Diseases in Adult Patients With Cystic Fibrosis

Clinical manifestations of respiratory fungal diseases in adult cystic fibrosis (CF) patients are very heterogeneous, ranging from asymptomatic colonization to chronic infections, allergic disorders, or invasive diseases in immunosuppressed CF patients after lung transplantation. In this narrative review, mainly addressed to clinicians without expertise in CF who may nonetheless encounter adult CF patients presenting with acute and chronic respiratory syndromes, we briefly summarize the most representative clinical aspects of respiratory fungal diseases in adult CF patients.
Effect of glycine betaine, polyvinylpyrrolidone and D-mannitol on micropropagation of Sideritis raeseri Boiss and Heldr. subsp. Raeseri.

Despite being protected, the number of plants that belong to Sideritis genus has decreased in the last years due to the urbanization of its natural habitat. Sideritis raeseri Boiss and Heldr. subsp. raeseri known as mountain tea of Parnassus or Velouchi is a valuable genetic resource of the Greek flora because of its special characteristics, so, the development of a micropropagation protocol is crucial to its conservation and use in breeding programs. The objectives of the study were to evaluate the effects of glycine betaine (GB), polyvinylpyrrolidone (PVP-10) and D-mannitol applied in different concentrations in combination with auxins [α-naphthaleneacetic acid (NAA), indole-3-butyric acid (IBA)] on shoot proliferation and rooting of shoot-tip explants of the studied species. Better shoot proliferation results were obtained in the following two combination treatments: (1) 100 mg/l GB + 0.5 mg/l NAA (5.5 shoots/explant 2.34 cm long, 75% shoot multiplication), and (2) 2.5 g/l D-mannitol + 3 mg/l IBA (2.92 shoot/explant 83.33% shoot multiplication percentage). In relation to rooting, better results were performed only with PVP at 0.5 g/l applied simultaneously with 0.5 mg/l NAA (12 roots/rooted microcutting, 1.47 cm root length, 90% rooting). The ex vitro survival percentage of rooted microcuttings derived from all 5 experiments was ranged between 68% and 93%.
Die Lohnfindung in Deutschland in einer internationalen Perspektive: Ist das deutsche System ein Auslaufmodell?

Der Beitrag untersucht verschiedene Aspekte des Lohnfindungsprozesses und geht international vergleichend der Frage nach, inwieweit die Regelungen in Deutschland geandert werden mussen. Im Mittelpunkt stehen dabei die Lohnstruktur u.a. auch im Zusammenhang mit der Schaffung von Arbeitsplatzen fur Problemgruppen, der Zentralisierungsgrad von Lohnverhandlungen in Verbindung mit der Diskussion um den Flachentarifvertrag, effiziente Vertrage uber Lohnhohe und Beschaftigung sowie einige Bemerkungen zur Streikaktivitat. Abschliesend werden einige mogliche Innovationen im Tarifvertragssystem diskutiert. Der Beitrag kommt zum Ergebnis, das das deutsche Modell der Lohnfindung kein Auslaufmodell darstellt, eine behutsame Modellpflege gleichwohl unerlaslich ist.
Bayesian uncertainty‐directed dose finding designs

We introduce Bayesian uncertainty‐directed (BUD) designs for phase I–II dose finding trials. This class of designs assigns patients to candidate dose levels with the aim of maximizing explicit information metrics at completion of the trial, while avoiding the treatment of patients with toxic or ineffective dose levels during the trial. Explicit information metrics provide, at completion of the clinical study, accuracy measures of the final selection of optimal or nearly optimal dose levels. The BUD approach utilizes the decision theoretic framework and builds on utility functions that rank candidate dose levels. The utility of a dose combines the probabilities of toxicity events and the probability of a positive response to treatment. We discuss the application of BUD designs in two distinct settings; dose finding studies for single agents and precision medicine studies with biomarker measurements that allow dose optimization at the individual level. The approach proposed and the simulation scenarios used in the evaluation of BUD designs are motivated by a stereotactic body radiation therapy study in lung cancer at our institution.
Instagram and art gallery visitors: Aesthetic experience, space, sharing and implications for educators

Instagram is one of the world's most popular social media applications. For art galleries it is an important tool for promotion, marketing, interaction, participation and the enhancing of the visitor experience. For arts educators it is an opportunity to broaden the participation of people wanting to learn through art, and to consider how Instagram may contribute to an art gallery based learning program. There is limited research about the use of Instagram by visitors to an art gallery and the role it plays in their experience. This article is drawn from a research study into the use of Instagram by visitors to the Gerhard Richter exhibition at the Queensland Gallery of Modern Art (14 October 2017 - 4 February 2018). The research project, which was informed by spatial theory, found that the use of Instagram at the gallery engaged visitors in a manner that transcended the physical space and extended their aesthetic experience. This finding is significant for arts educators seeking to engage students through social media during visits to art exhibitions.

This is a useful reference book, well presented, including illustrations, but the problems of research and the question as to the overall place of the technique in the care of patients, must still remain uncertain.
Longer, smaller, faster, stronger: On skills and intelligence

ABSTRACT How does practice change our behaviors such that they go from being awkward, unskilled actions to elegant, skilled performances? This is the question that I wish to explore in this paper. In the first section of the paper, I will defend the tight connection between practice and skill and then go on to make precise how we ought to construe the concept of practice. In the second section, I will suggest that practice contributes to skill by structuring and automatizing the motor routines constitutive of skilled actions. I will cite how this fact about skilled action has misled many philosophers to conclude that skills are mindless or bodily. In the third section of the paper, I will challenge this common misconception about automaticity by appealing to empirical evidence of motor chunking. This evidence reveals that there are two opposing processes involved in the automaticity of skilled action: one process that is largely associative, which I will call “concatenation,” and a second which is a controlled cognitive process, which I will call “segmentation. ” As a result of this evidence, we will be in a position to see clearly why skills are minded and intelligent not merely during their acquisition and not simply in virtue of their connection to intentional states but, rather, in their very nature. I will end by reflecting on some theoretical reasons for why this is exactly what we should expect to be the case when it comes to skilled action.
Optimal Operating Conditions Based on Mode Competition for Maximum Efficiency of Double-Strapped Magnetron

A magnetron is used as a core element in various fields such as environment, medical, and space, and in high-power microwave (HPM) for electromagnetic compatibility (EMC). Therefore, the efficient design of the magnetron is important for a system to function. This paper describes the optimal operating conditions to design <inline-formula> <tex-math notation="LaTeX">$L$ </tex-math></inline-formula>-band double-strapped magnetron with the maximum efficiency. We analyze the relationship between mode competition and operating points for <inline-formula> <tex-math notation="LaTeX">$\pi $ </tex-math></inline-formula>-mode oscillation. Understanding the phenomenon that all formable modes compete with each other based on the force from the <inline-formula> <tex-math notation="LaTeX">$E$ </tex-math></inline-formula>-field for each mode and the cyclotron frequency in a given operating condition, we find the operating conditions for maximum efficiency of the magnetron. Simulations are performed using a particle-in-cell (PIC) solver of a highly reliable CST-particle studio (PS) tool, and the details are explained. In addition, various output characteristics of the operating conditions of the magnetron are described.
Market Reactions to Changes in the Dow Jones Industrial Average Index

Purpose The purpose of this paper is to examine changes in stock returns, liquidity, institutional ownership, analyst following and investor awareness for companies added to and deleted from the Dow Jones Industrial Average (DJIA) index. Previous studies report conflicting evidence regarding the market reactions to changes in the DJIA index membership. Design/methodology/approach This study uses the event-study methodology to calculate abnormal returns and trading volume around the announcement and effective days of DJIA index changes from 1929 to 2015. It also tests for significant changes in liquidity, institutional ownership, analyst following and investor awareness in the 1990–2015 period. Multivariate regressions are used to perform a simultaneous analysis of competing hypotheses. Findings This study resolves the mixed results of previous DJIA index papers by documenting different stock price and trading volume reactions over the 1929–2015 period. Focusing on the most recent period, 1990–2015, the study finds that stocks added to (deleted from) the index experience a significant permanent stock price gain (loss). The observed stock price reaction seems to be associated with changes in liquidity proxies thus lending support for the liquidity hypothesis. Research limitations/implications Limited data availability for the periods prior to 1990 prevents this study from identifying the exact reasons for different stock price and trading volume reactions across subperiods of the 1929–2015 period. Originality/value This study provides the most comprehensive examination of market reactions to changes in the DJIA index and resolves the mixed results of previous studies. A better understanding of market reactions around the DJIA index changes can help both individual and institutional investors with developing effective trading strategies and index managing companies with designing optimal announcement policies.
Drivers, Process, and Consequences of Native Grassland Degradation: Insights from a Literature Review and a Survey in Río de la Plata Grasslands

Natural grasslands are being progressively degraded around the world due to human-induced action (e.g., overgrazing), but there is neither a widely accepted conceptual framework to approach degradation studies nor a clear definition of what “grassland degradation” is. Most of the drivers, processes, and consequences related to grassland degradation are widespread and are usually separately quoted in the literature. In this paper, we propose a comprehensive framework with different conceptual categories, for monitoring grassland degradation, and a new definition based on current ones. We provide a conceptual update of grassland degradation based on a literature review and an expert survey, focused on the Río de la Plata grasslands (RPG). We identified “drivers” as external forces or changes that cause degradation; “processes” as measurable changes in grasslands conditions that can be evaluated using indicators; and “consequences” as the impacts or results of the process of grassland degradation. We expect that this conceptual framework will contribute to monitoring programs, to support management decisions, to design conservation measures, and to communicate the importance of grasslands conservation and the different concepts involved. Particularly for RPG, we expect that this paper will contribute to promote sustainable management practices in this important and often neglected ecosystem.
