Indoor Radio Noise Long-Term Measurements in Medium Wave Band in Buildings of City Areas in the North of Spain

This letter presents a study of indoor radio noise levels in the Medium Wave band up to 2 MHz, based on field trials. The work is based on long-term measurements carried out in buildings located in the areas of Bilbao and Vitoria in the north of Spain. The studied channels are centered in 630, 675, 1035, 1242, 1359, 1620, 1720, and 1910 kHz. The noise variation between daytime and nighttime and the variation depending on the type of building, office or household, have been analyzed. The obtained values, compared to the values predicted in ITU-R P-372 for outdoor locations in city environments, are higher. Reference values for radio planning are given for these frequency bands.
Property Tax Policy and Land-Use Change

In this study, we analyze the effect of property taxes on changes between agricultural, forestry, Conservation Reserve Program, and developed land uses in Louisiana. We estimate a random parameters logit model of land-use conversion from the National Resources Inventory plot data. Our results indicate that land-use changes are inelastic with respect to property taxes. Simulation shows that current use valuation policy, while slowing down development of rural lands, also affects changes between rural land uses. (JEL Q15, H23)
A model of knowledge mapping in visualizing the hotspot of dengue

Formulation process is very important in model development. Due to that, this study was performed as a formulation process for the K-Map model development in order to visualize the dengue hotspot. Purpose of this study is to find the appropriate technique on knowledge visualization and also to identify the contributing parameters for the dengue outbreak. Methodology that has been used is by analysing the literature review from empirical paper. Result from this study shows that Venn diagram is one of the technique that can be used to visualize the dengue hotspot while the environmental parameter is one of the contributing factors in dengue transmission and distribution. Ten environmental parameters that are land use, housing types, Land Surface Temperature, Elevation, Soil Moisture, Greenness, Population Density, rainfall, temperature and humidity have been identified. As a conclusion, climate change impact is one of the environmental parameter, which influences the trend of dengue transmission and distribution. The impact of climate change on the transmission patterns of dengue diseases can be both direct and indirect. A direct impact describes how the changes in precipitation and temperature trend can influence the trend of the dengue transmission and distribution pattern. Instead indirect impact describe how the factors such as human population dynamics and their effects on exposure risk, changes in vegetation, hydrology and other landscape features can influence the trend of dengue transmission and distribution pattern.
SECO: SDN sEcure COntroller algorithm for detecting and defending denial of service attacks

Software Defined Network (SDN) brings additional flexibility to the traditional network allowing the implementation of intelligent information processing. SDN introduces a new architecture, where the controller acts as the brain of the network controlling several tasks such as routing, load balancing and providing the required quality of service (QoS). However, having a centralized controller makes the network vulnerable in terms of security. This paper introduces SDN sEcure COntroller (SECO) a novel and simple detect and defense algorithm, running in the controller, for improving SDN security features under Denial of Service (DoS) attacks. The network performance during attack is tested with and without the SECO algorithm. In this paper we show by means of simulations that the DoS attacks can degrade the controller's performance and the proposed algorithm could significantly reduce the impact of such DoS attacks.
Managerial Reputation and Corporate Investment Decisions

This review examines the incentives of managers to use investment choices as a tool for building their personal reputations or the reputation of their firms. These incentives come in three main forms: visibility bias, which encourages a manager to try to make short-term indicators of success look better; resolution reference which encourages a manager to try to advance the arrival of good news and delay bad news; and mimicry and avoidence, which encourages a manager to take the actions that the best managers are seen to do, and to avoid the actions the worst managers are seen to do.

Induction of Chitin-Binding Proteins during the Specific Attachment of the Marine Bacterium Vibrio harveyi to Chitin

Previous work has shown that attachment of Vibrio harveyi to chitin is specific and involves at least two chitin-binding peptides. However, the roles and regulation of these chitin-binding peptides in attachment are still unclear. Here we show that preincubation with the oligomeric sugars composing chitin stimulated chitinase activity, cellular attachment to chitin, and production of chitin-binding peptides. One of these peptides, a 53-kDa peptide, is produced constitutively and appears to mediate initial attachment to chitin. Synthesis of another peptide, a 150-kDa chitin-binding peptide, is induced by chitin and thus may be involved in time-dependent attachment. Coordinated regulation of attachment and degradation of chitin may give bacteria like V. harveyi a selective advantage over other bacteria in nutrient-poor aquatic environments.
Grid voltage modulated direct power control for grid connected voltage source inverters

We propose a grid voltage modulated (GVM) direct power control (DPC) strategy for a grid-connected voltage source inverter (VSI) to control the instantaneous active and reactive powers. The GVM-DPC presents the system in d-q frame without using a phase-lock loop. In addition, the GVM method converts the system into a linear time-invariant system. The GVM-DPC is designed to obtain two separate second-order systems for not only the convergence rate of the instantaneous active and reactive powers but also the steady-state performance. In addition, the closed-loop system is exponentially stable in the whole operating range. The proposed method is verified by using MATLAB/Simulink with PLECS blockset. The simulation results show that the proposed method has not only good tracking performances in both active and reactive powers but also a lower current total harmonic distortion than that of the sliding mode control DPC method. Finally, the proposed method is validated by using a hardware-in-the-loop system with a digital signal processor. The experimental results are similar to simulation results. Moreover, the robustness to the line impedance and the grid voltage is tested and discussed.
Genomic Abnormalities in Gliomas

In general, studies reveal that cancer arises through genetic and epigenetic alterations that affect specific genes within a given cell type. These changes involve a gain of function when the alterations involve oncogenes, a loss of function when the target genes are tumor suppressor genes. Thus, both genetic and epigenetic changes promote the instability of cellular homeostasis (Bello & Rey, 2006; Richardson, 2003; Sugimura & Ushijima, 2000). This lack of stability reflects the complexity of cancer because the loss of controlled cell growth occurs due to changes in one or more genes. These genetic and epigenetic events are followed by the growing accumulation of changes in hundreds, if not thousands, of genes. Over time, this accumulation causes the tumor to reach its highest degree of malignancy, which usually culminates in metastasis (Bartek & Lukas, 2001). However, in recent years, a subpopulation of tumor cells has been found to display a slow rate of cell division, high tumorigenic potential and characteristics similar to those of normal stem cells. This discovery has changed the concept of metastasis to one associated with strictly terminal states (Stiles & Rowitch, 2008). Hanahan & Weinberg (2000) proposed that all tumor cells must acquire six essential alterations in cell physiology that collectively dictate malignant growth: (1) loss of normal signaling for cell proliferation arrest, (2) loss of signaling for cell differentiation, (3) autocrine signaling for cell division, (4) reduction in apoptosis, (5) ability to enter the basement membrane and other tissues and organs, and (6) induction of angiogenesis. All of these processes involve biochemical pathways that form a complex network of cell signaling. These processes are usually altered in tumors because the genes that compose them are changed, resulting in cell cycle dysregulation. Therefore, the identification and determination of oncogenes and tumor suppressor genes is essential for understanding both cancer biology and clinical applications, such as the identification of therapeutic targets, early detection, and prediction of the disease course. Studies concerning cell cycle control genes have served as a starting point for identifying genes related to tumorigenesis and their biochemical role in various pathways (Paige, 2003).
A Small Scale Experimental Study: Using Animations to Learn Vocabulary

This study attempts to investigate whether a difference exists between learning vocabulary via animation and via traditional paper-based method. This small scale study was conducted at Karadeniz Technical University in academic year 2009-2010. Two pre-intermediate classes were randomly selected as the experimental group (n=17), and control group (n=22) as each class accommodated that number. Results obtained from the data gathered with a pre-test and a post-test applied to each group was analyzed using t-test in SPSS 16.00 version. The findings show that although there is no statistically significant difference between post-tests of each group, there was an increase in the post-test scores of animation group as compared to the pre-test scores. This increase implies that using multimedia such as animations contribute to students’ achievement in vocabulary learning. Besides, the teachers’ observations and students’ opinions indicate that there were relatively positive attitudes towards using such kind of animations in vocabulary learning. They were useful since they address more senses than using paper-based texts; however, they can be distractive if teachers do not pay attention to the proficiency level of students and the content presented. The study supports the idea that multimedia applications can be integrated into language classes not as an alternative way but as an additional way to contribute positively to the
Reach‐scale manipulations show invertebrate grazers depress algal resources in streams

Experimental tools that enable manipulations of organisms at larger scales allow for comparisons of processes across multiple spatial scales and expand our ability to make predictions about ecological processes. We performed reach scale (i.e., 50 m2) manipulations of invertebrate communities in streams using a modified electroshocking technique to nondestructively remove invertebrates. In addition, we conducted a microcosm experiment (i.e., 157 cm2) with different grazer densities that enabled comparison of the strength of grazer‐algal interactions at large and small spatial scales. In high elevation headwater streams, electroshocking reduced total invertebrate abundance by 84% in a 50‐m2 reach of stream. Although mobile invertebrates recolonized the manipulated area rapidly, daily electroshocking maintained the density reduction. Electroshocking reduced the density of herbivorous invertebrates 86%, which resulted in a 57% increase in algal biomass, whereas in a stream that was not electroshocked, invertebrate density and algal biomass changed much less, only 16 and 8%, respectively. Comparison of grazer effect on periphyton between microcosm and reach‐scale experiments revealed that the per capita interaction strength of grazers on primary producers was three times greater in the reach‐scale manipulation than that observed in the microcosm experiments. Reach‐scale manipulation of invertebrate grazers in streams provides a powerful method to experimentally test patterns observed in the field at a large spatial scale, with more realism than streamside microcosms or small cages in streams.
Galaxy Zoo:CANDELS barred discs and bar fractions

The formation of bars in disk galaxies is a tracer of the dynamical maturity of thepopulation. Previous studies have found that the incidence of bars in disks decreasesfrom the local Universe to z ∼ 1, and by z > 1 simulations predict that bar featuresin dynamically mature disks should be extremely rare. Here we report the discoveryof strong barred structures in massive disk galaxies at z ∼ 1.5 in deep rest-frameoptical images from CANDELS. From within a sample of 876 disk galaxies identifiedby visual classification in Galaxy Zoo, we identify 123 barred galaxies. Selecting a sub-sample within the same region of the evolving galaxy luminosity function (brighterthan L), we find that the bar fraction across the redshift range 0.5 ≤ z ≤ 2 (fbar =10.7+6.3−3.5% after correcting for incompleteness) does not significantly evolve.We discussthe implications of this discovery in the context of existing simulations and our currentunderstanding of the way disk galaxies have evolved over the last 11 billion years.

Big Data for Big Business? A Taxonomy of Data-driven Business Models used by Start-up Firms

Why this paper might be of interest to Alliance Partners: This paper reports a study which provides a series of implications that may be particularly helpful to companies already leveraging ‘big data’ for their businesses or planning to do so. The Data Driven Business Model (DDBM) framework represents a basis for the analysis and clustering of business models. For practitioners the dimensions and various features may provide guidance on possibilities to form a business model for their specific venture. The framework allows identification and assessment of available potential data sources that can be used in a new DDBM. It also provides comprehensive sets of potential key activities as well as revenue models. The identified business model types can serve as both inspiration and blueprint for companies considering creating new data-driven business models. Although the focus of this paper was on business models in the start-up world, the key findings presumably also apply to established organisations to a large extent. The DDBM can potentially be used and tested by established organisations across different sectors in future research.
Phylogenetic Patterns in Northern Hemisphere Plant Geography

Geological and climatological processes that have impacted the biota of the Northern Hemisphere during the Tertiary are expected to yield little resolution when area cladograms are compared without taking the timing of diversification into account. In an attempt to establish a set of appropriate phylogenetic comparisons, we distinguished between a Pacific track involving (minimally) China, Japan, and eastern North America but not Europe, and an Atlantic track involving China, Europe, and eastern North America but not Japan (or, in most cases, western North America). Within the two Atlantic‐track taxa considered here—Liquidambar and Cercis—European and North American species are more closely related to one another than they are to the Asian species. Within a set of five Pacific‐track taxa—Hamamelis, Weigela‐Diervilla, Triosteum, Buckleya, and Torreya—we see all possible relationships involving China, Japan, and eastern North America. Estimates of minimum divergence times between Old World and New World lineages, based on molecular and fossil evidence, differ markedly between the two Atlantic‐track clades. Among the Pacific‐track taxa, we find no correlation between pattern of area relationships and estimated divergence times of the Old World–New World disjuncts. Instead, we see a wide range in the timing of these splitting events among and within phylogenetic patterns. Despite the existence of a variety of patterns, inferred ancestral areas and divergence times can be explained by assuming initial diversification within Asia in a number of lineages, followed by iterative trans‐Beringian dispersion and vicariance.
Testing for Welfare Comparisons When Populations Differ in Size

Assessments of social welfare do not usually take into account population sizes. This can lead to serious social evaluation flaws, particularly in contexts in which policies can affect demographic growth. We develop in this paper a little-known though ethically attractive approach to correcting the flaws of traditional welfare analysis, an approach that is population-size sensitive and that is based on critical-level generalized utilitarianism (CLGU). Traditional CLGU is extended by considering arbitrary orders of welfare dominance and ranges of “poverty lines” and values for the “critical level” of how much a life must be minimally worth to contribute to social welfare. Simulation experiments briefly explore the normative relationship between population sizes and critical levels. We apply the methods to household level data to rank Canada’s social welfare across 1976, 1986, 1996 and 2006 and to estimate normatively and statistically robust lower and upper bounds of critical levels over which these rankings can be made. The results show dominance of recent years over earlier ones, except when comparing 1986 and 1996. In general, therefore, we conclude that Canada’s social welfare has increased over the last 35 years in spite (or because) of a substantial increase in population size.
Immunogenicity and protective efficacy of Vibrio vulnificus flagellin protein FlaB in a wound infection model

Vibrio vulnificus is known as an opportunistic bacterial pathogen that causes primary septicemia and wound infection in humans. Recently, the incidence of wound infection by V. vulnificus is increasing in warm countries. In this study, we examined a vaccine antigen against V. vulnificus in mice. FlaB, a component protein of the V. vulnificus flagellum, was expressed as a recombinant protein, named rFlaB. After immunization of mice with rFlaB, the mice were challenged by subcutaneous inoculation with V. vulnificus. Bacterial burdens in muscular tissue at the infection site in rFlaB-immunized mice were significantly decreased compared with those of control mice. We found that rFlaB immunization can partially suppress proliferation of V. vulnificus at the local infection site.
STOCK PRICE BEHAVIOR OF PURE CAPITAL STRUCTURE ISSUANCE AND CANCELLATION ANNOUNCEMENTS

I examine planned senior-for-junior and junior-for-senior transactions that are subsequently canceled. I find statistically significant stock returns for issuance and cancellation announcements that are positively related to the direction of the leverage change. The magnitude and direction of the returns differ from previous research. Discrepancies are attributed to different issuance purposes.
Static Zero-Power-Consumption Coplanar Waveguide Embedded DC-to-RF Metal-Contact MEMS Switches in Two-Port and Three-Port Configuration

This paper reports on novel electrostatically actuated dc-to-RF metal-contact microelectromechanical systems (MEMS) switches, featuring a minimum transmission line discontinuity since the whole switch mechanism is completely embedded inside the signal line of a low-loss 3-D micromachined coplanar waveguide. Furthermore, the switches are based on a multistable interlocking mechanism resulting in static zero-power consumption, i.e., both the onstate and the offstate are maintained without applying external actuation energy. Additionally, the switches provide with active opening capability, potentially improving the switch reliability, and enabling the usage of soft low-resistivity contact materials. Both two-port single-pole-single-throw (SPST) switches featuring mechanical bistability and three-port single-pole-double-throw (SPDT) T-junction switches with four mechanically stable states are presented. The switches, together with the transmission lines, are fabricated in a single photolithography process. The loss created by the discontinuity of the switch mechanism alone is 0.08 dB at 20 GHz. Including a 500 m long transmission line with less than 0.4 dB/mm loss up to 20 GHz, the total insertion loss of the two-port devices is 0.15 and 0.3 dB at 2 and 20 GHz, and the isolation is 45 and 25 dB at 2 and 20 GHz. The three-port switches, including their T-junction transmission line, have an insertion loss of 0.31 and 0.68 dB, and an isolation of 43 and 22 dB, at 1 and 10 GHz, respectively. Actuation voltages are 23-39 V for the two-port switches and 39-89 V for the three-port switches. The microwave propagation in the micromachined transmission line and the influence of the different switch designs were analyzed by finite-element method (FEM) simulations of electromagnetic energy and volume current distributions, proving the design advantages of the proposed concept.
