A Socio-technical Interpretation of Digital Multimedia Service: Applying a Perspective from ANT and CAS

The advances in Information and Communication Technology that have revolutionized almost every domain of industry and society have, among other developments, ushered in a new era of convergence services. Such a process of convergence in the supply chain network, however, can create a new dimension of network complexity, precipitating dynamic behavior among actors. This paper seeks to understand how different actors in value chain networks have co-evolved in practice with the development of converged digital multimedia services. An interpretative case study was undertaken to examine how different actor network adapted in different ways to shape the overall complexity of the converged service from the combined framework of Complex Adaptive Systems (CAS) and Actor Network Theory (ANT). By analyzing the case of DMB in Korea, the proposed framework suggested a possible synthesis between CAS and ANT. This synthesis offers a way to characterize the drivers of coevolutionary behavior, capturing the translation processes undergone by actor networks in the formulation of converged services.
High-resolution physical-biogeochemical structure of a filament and an eddy of upwelled water off Northwest Africa

Abstract. Nutrient rich water upwells offshore of Northwest Africa and is subsequently advected westwards. There it forms eddies and filaments with a rich spatial structure of physical and biological/biogeochemical properties. Here we present a high resolution (2.5 km) section through upwelling filaments and an eddy obtained in May 2018 with a Triaxus towed vehicle equipped with various oceanographic sensors. Physical processes at the mesoscale and submesoscale such as symmetric instability, trapping of fluid in eddies, and subduction of low potential vorticity (which we use as a water mass tracer) water can explain the observed distribution of biological production and export. We found a nitrate excess (higher nitrate concentrations than would be expected from oxygen values if only influenced by production and remineralization processes) core of an anti-cyclonic mode water eddy. We also found a high nitrate concentration region of ~5 km width in the mixed layer where symmetric instability appears to have injected nutrients from below into the euphotic zone. A similar region a little further south had high chlorophyll-a concentrations suggesting that nutrients had been injected there a few days earlier. Considering that such interactions of physics and biology are ubiquitous in the world's upwelling regions, we assume that they have strong influences on the productivity of such systems and their role in CO2 uptake. The intricate interplay of different parameters at kilometer scale needs to be taken into account when interpreting single profile and/or bottle data in dynamically active regions of the ocean.
Effect of Couette Type of Shear Stress Field with Axial Shear Slope on Deformation and Migration of Cell: Comparison between C2C12 and HUVEC

A shear flow device contained in the microscope incubator has newly been designed to study the effect of the shear stress field on the biological cell in vitro. The culture medium was sandwiched with a constant gap between a lower stationary culture plate and an upper rotating parallel plate to make a Couette type of shear field with the perpendicular shear slope. The wall shear stress (τ) on the lower culture disk was controlled by the rotating speed of the upper disk. The shear stress τ increases in proportion to the distance from the axis of rotation. After cultivation for 24 hours for adhesion of cells on the lower plate without flow, τ < 2 Pa was applied on cells for 24 hours subsequently. HUVEC (human umbilical vein endothelial cell) tends to be elongated and aligned under < 2 Pa of the shear stress. C2C12 (mouse myoblast cell line), on the other hand, maintains elongated shape and tends to migrate to the lower shear stress direction (< 2 Pa). The experimental system is useful to study the quantitative relationships between the shear stress and the cell behaviors: deformation, orientation, and migration.
WebIsAGraph: A Very Large Hypernymy Graph from a Web Corpus

In this paper, we present WebIsAGraph, a very large hypernymy graph compiled from a dataset of is-a relationships extracted from the CommonCrawl. We provide the resource together with a Neo4j plugin to enable efﬁcient searching and querying over such large graph. We use WebIsAGraph to study the problem of detecting polysemous terms in a noisy termi-nological knowledge graph, thus quantifying the degree of polysemy of terms found in is-a extractions from Web text.
Hydrothermal Synthesis of (001) Facet Highly Exposed ZnO Plates: A New Insight into the Effect of Citrate

In this work, two synthesis routes were applied to investigate the effect of citrates on the construction of the ZnO structure. Well-dispersed ZnO plates with (001) facet highly exposed were prepared via one-step hydrothermal route, while ZnO nanoparticles were obtained via two-step route. In one-step route, citrates were added before the formation of Zn(OH)2 precursor, while citrates were added after the formation of Zn(OH)2. For the first time, the interaction between citrates and the Zn(OH)2 precursor was investigated and citrates that participated in the formation of Zn(OH)2 were the main cause for (001) facet exposed structure construction. A growth mechanism about the formation of ZnO plates in the presence of citrates was proposed. The as-prepared ZnO plates showed enhanced photocatalytic activity for the degradation of methylene blue (MB).
The cusum test in time series models

In this paper we consider the problem of testing for a scale change in the infinite order moving average process, for the parameters in unstable models, and for those of regression models with ARCH errors. For performing the test, the cusum of squares test analogous to Inclán and Tiao (1994)’s statistic is considered.
Optimal depth jump height quantified as percentage of athlete stature

Purpose: An individual’s optimal depth jump platform height provides a resistive force which allows an athlete to rebound with substantial velocity resulting in maximum power exertion. The objective of this investigation was to show that the optimal platform height in a depth jump can be quantified as a percentage of individual body stature which can serve as measurable quantified value. Although athlete height is not highly correlated to power ability nor does a universal height exist, this value can provide a basis for a rehabilitation or strength and conditioning program. The desired intensity of a program can be prescribed as a percentage of the individual’s optimal drop height. Methods : Sixteen male participants (age = 21.7 ± 1.54 yrs., height = 177.7 ± 11.4 cm, mass = 77.7 ± 13.6 kg; mean ± SD) were tested in a depth jump through a range of platform heights based on percentage of the individual anthropometric data defined at 0-, 10-, 20-, 30-, 40-, and 50% of the participants’ stature using a 3-D motion capture system (Qualysis) and force plates (Bertec) to calculate power. Results : The optimal drop height was found to be 21.3 (±10.3)% of the participants’ heights for maximum peak power and 27.5 (±15.3)% for maximum average power. Conclusions : These results suggest that an individual optimal drop height does exist as a percentage of stature and could be applied to a rehabilitation or power-based training program using the drop height as a quantified basis allowing an athlete to gradually work toward their individual optimal drop height and exhibit maximum power.
Analysis of the internal strategic alignment of the production strategy: case study in an auto parts company of the municipality of Sorocaba/SP

Abstract The auto parts sector plays an important role in the national economy and has the need to become more competitive in face of some difficulties in the current context. In this scenario, it is considered of great importance the alignment of the production strategy and its contribution to the competitiveness of the sector in the country. Thus, the research aims to analyze, based on methods proposed in the literature, the degree of internal alignment of the production strategy in two segments of one company in the auto parts sector. The method adopted was the case study, being the research of combined character that makes use of the qualitative and quantitative approach. Among the main results, it can be seen that, although the organization analyzed has more control over the production process technologies for products that serve the commercial vehicle market, there are efforts to reduce the product portfolio and standardize the products offered in the market. with cost as the competitive priority emerging.
Application of Similarity Method of Distance Courses Describing the Elements Content in Pavement Quality Concrete

Abstract The publication presents the application of similarity analysis of distance courses. This method has been applied to define similarity of cement concrete intended for airfield pavements. The scope of works included standard concretes intended for airfield pavements and concretes after frost resistance test. The test has been conducted in diversified media used in the course of winter maintenance. The nature of resistance of pavement quality concrete was discussed with respect to frost resistance thereof. Research procedure was presented and the obtained laboratory tests results were discussed. Concrete samples were subject to observations using scanning electron microscope in order to define changes occurring in the internal microstructure. Chemical microanalysis of concrete composition before, in the course of and after the frost resistance test and the occurring changes were specified. The obtained laboratory tests results were intended for the purposes of the similarity analysis. Results obtained in case of standard pavement quality concrete were considered as comparative values. Characteristics of the remaining concretes were referred to these values and then similarity of distance courses were analysed. It was proved that BWMt concrete was the most similar concrete to the comparative concrete.

Prendo la Parola in Questo Consesso Mondiale: A Multi-Genre 20th Century Corpus in the Political Domain

English. In this paper we present a multigenre corpus spanning 50 years of European history. It contains a comprehensive collection of Alcide De Gasperi’s public documents, 2,762 in total, written or transcribed between 1901 and 1954. The corpus comprises different types of texts, including newspaper articles, propaganda documents, official letters and parliamentary speeches. The corpus is freely available and includes several annotation layers, i.e. key-concepts, lemmas, PoS tags, person names and geo-referenced places, representing a high-quality ‘silver’ annotation. We believe that this resource can foster research in historical corpus analysis, stylometry and computational social science, among others.1
Using AI to Attack VA: A Stealthy Spyware Against Voice Assistances in Smart Phones

Voice Assistants (VAs) are increasingly popular for human-computer interaction (HCI) smartphones. To help users automatically conduct various tasks, these tools usually come with high privileges and are able to access sensitive system resources. A comprised VA is a stepping stone for attackers to hack into users’ phones. Prior work has experimentally demonstrated that VAs can be a promising attack point for HCI tools. However, the state-of-the-art approaches require ad-hoc mechanisms to activate VAs that are non-trivial to trigger in practice and are usually limited to specific mobile platforms. To mitigate the limitations faced by the state-of-the-art, we propose a novel attack approach, namely Vaspy, which crafts the users’ “activation voice” by silently listening to users’ phone calls. Once the activation voice is formed, Vaspy can select a suitable occasion to launch an attack. Vaspy embodies a machine learning model that learns suitable attacking times to prevent the attack from being noticed by the user. We implement a proof-of-concept spyware and test it on a range of popular Android phones. The experimental results demonstrate that this approach can silently craft the activation voice of the users and launch attacks. In the wrong hands, a technique like Vaspy can enable automated attacks to HCI tools. By raising awareness, we urge the community and manufacturers to revisit the risks of VAs and subsequently revise the activation logic to be resilient to the style of attacks proposed in this work.
WINDOW ANALYSIS OF TECHNICAL EFFICIENCY: CASE OF THE SLOVAK BANKING SYSTEM

In the paper, a time-dependent use of data envelopment analysis (DEA) that is known as “window analysis” is applied to a set of banking institutions in Slovakia with an aim to measure their technical efficiency in period 2000 – 2012. It is assumed that the production function remains unchanged and the banking institutions perform activities under variable returns to scale. The non-parametric method of evaluation, based on the input-oriented efficiency slacks-based measure model of data envelopment analysis (SBM) is employed. The paper contributed to so far published literature by addressing the efficiency coefficients variation through window and by term in the scope of the transmission approach to the banking functions. Gained results of the case study applied on the Slovak conditions can be utilized for managerial and regulatory purposes.

PATH DEPENDENCE AND REGIONAL PATHS OF PROCESS CHANGES IN THE RUSSIAN INDUSTRY

Purpose: The regional economy depends on the structure of industrial production which has been established earlier. This study makes it possible to determine the hi-tech spheres in which the entrepreneurship is going to develop more successfully. The purpose of the investigation is to determine the technological proximity of the industrial production branches with the high-tech economy sector for further defining the egress from the previous development path. Design/methodology/approach: In order to determine possible egress of the region from the previous development trajectory there has been proposed a method of proximity evaluation between the high-tech sector and the existing structure of industrial production in the region. The characteristics of high technologies relatedness to other industry branches in the Russian regions have been defined. Findings: For the Russian regions it was determined that less than 30% of sub-branches can be considered as connected with the high technology sector 25%. The regions having the comparative advantages in the high-tech types of industry and sectors related thereto have been revealed. We have demonstrated that individual regions can progress through investment into interregional connections and entrepreneurship domestic innovations. Research/practical implications: Considered as the investigatory contribution of the paper can be the alternative proposed to the comparative advantage index in the form of a localization coefficient to be used at evaluation of the technological proximity of industrial branches. The results of this study can be of benefit to representatives of the regional managerial bodies in the course of the economic policy development in the sphere of entrepreneurship. Originality/value: Proposed in the article is a method for evaluation of technological proximity of industry branches which differs from the traditional use of the localization coefficient. The calculated proximity indexes make it possible to determine such high-tech industries to the development of which there are the necessary prerequisites in the region, i.e. the technologically similar industrial production is under development.
Wiar: A Public Dataset for Wifi-Based Activity Recognition

We construct a public dataset for WiFi-based Activity Recognition named WiAR with sixteen activities operated by ten volunteers in three indoor environments. It aims to provide public signal data for researchers to reduce the cost of collected signal data and conveniently evaluate the performance of WiFi-based human activity recognition in different domains. First, we introduce the basic knowledge of WiFi signals regarding RSSI, CSI, and wireless hardware. Second, we explain the characteristics of WiAR dataset in terms of activities types, data format, data acquisition ways, and influence factors. Third, the proposed framework can estimate the quality of the shared signal data provided by other peers. Finally, we select and use five classification algorithms and two deep learning algorithms to evaluate the performance of WiAR dataset on human activity recognition. The results show that the accuracy of WiAR dataset is higher than 80% using machine learning algorithms and 90% using deep learning algorithms in different indoor environments.
Troglobites from the Lava Tubes in the Sierra de Chichinautzin, Mexico, Challenge the Competitive Exclusion Principle

The Sierra de Chichinautzin is located south of Mexico City and north of Cuernavaca, in Mexico. This volcanic mountain range had, in relatively recent times, (Holocene) at least seven lava flows with the formation of lava tubes (Espinasa-Pereña, 1999). Multiple caves of great extension can be found in this mountain range, including the Cueva del Ferrocarril, the largest lava tube in the Americas, at about 6 km, and Cueva de la Iglesia, at about 5 km. A detailed description of most of the cave systems in the area can be found in EspinasaPereña (1999, 2006). Some of the Sierra de Chichinautzin lava tubes are inhabited by cave adapted silverfish insects (Cubacubaninae: Nicoletiidae: Insecta). Nicoletiids are one of the most important and common representatives of cave adapted fauna in the Neotropics and southern North America. While studying the relationships within the subfamily Cubacubaninae, Espinasa et al. (in press) included three troglobitic individuals from three different lava tubes from the Sierra de Chichinautzin: Cueva de la Iglesia, Cueva del Aire, and Cueva del Naranjo Rojo. Contrary to what might be expected due to the geographical proximity of the caves, the sequence data from five loci showed that the individuals belonged to two different species. The individual from Cueva de la Iglesia actually appeared to be more closely related to a species from a near surface locality, the town of Alpuyeca, than to its neighboring troglobite (Fig. 1). The purpose of this study is to better understand how many species of troglobitic nicoletiid insects inhabit the lava tubes of the Sierra de Chichinautzin, their distribution, and their dispersal capabilities among caves.

MINIATURIZED SUSPENDED-SUBSTRATE TWO-CONDUCTORS RESONATOR AND A FILTER ON ITS BASE

The paper is devoted to an investigation of two-conductor suspended-substrate resonators. For the purpose of miniaturization conductors of a resonator are folded. Four types of the resonator differing in conductors’ configurations were considered. Their Q0-factors and resonant frequencies were studied. Based on results of the study two types of the resonator appeared unsuitable for an application in compact filters. Two other types were investigated in concern of their interaction: dependencies of coupling coefficients versus space between resonators and versus distance from substrate’s surfaces, and package’s covers were obtained. Based on the dependences a type of the resonator suitable for designing compact BPF was chosen. A four-pole BPF was simulated and fabricated. Good agreement between simulated and experimental results is observed. The main filter’s characteristics are the next: substrate has ε = 80, thickness 0.5 mm, lateral sizes 0. 13λg × 0. 09λg (18.7mm× 13.2 mm). The central frequency is 305 MHz; bandwidth is 39 MHz; passband minimum insertion loss is 2.0 dB; passband return loss is less −14.6 dB; −40 dB stopband width is 480 MHz.
