The genus Dermoloma is more diverse than expected and forms a monophyletic lineage in the Tricholomataceae

We present the first phylogenetic evaluation of the genus Dermoloma , which is resolved as monophyletic and closely related to Pseudotricholoma , a poorly known Dermoloma -like lineage within the family Tricholomataceae. The position of Dermoloma is confirmed by the placement of the type species, Dermoloma cuneifolium , represented by multiple samples including the neotype. Based on our phylogenetic analyses, we recognised 25 European operational taxonomic units (OTUs) but could only assign species names to ten of them based on ex-type sequences. Furthermore, only five additional published Dermoloma names of uncertain status are available for the remaining 16 potential European species, thus demonstrating an unexpected amount of taxonomic diversity. Samples from Europe and North America seem to be endemic on a continental scale. North American samples formed six unique OTUs, but only one could be reliably named, Dermoloma hymenocephalum . Dermoloma is morphologically defined by basidiomata with brown, grey and white colours with a farinaceous odour and a pluristratous hymeniderm type of pileipellis. Our phylogenetic analyses support the subdivision of the genus into two subgenera and four sections, and species with inamyloid basidiospores are placed in subg. Dermoloma and those with amyloid basidiospores in subg. Amylospora . Both subgenera are further divided into two sections. The analysis of spore morphology shows that sect. Conica of subg. Dermoloma and sect. Nigrescentia of subg. Amylospora have a very distinctive spore shape. Sect. Atrobrunnea of subg. Amylospora showed relatively high variability of spores among species, but spores of sect. Dermoloma were similar and not useful for species discrimination.
Everything Flows: Studying Continuous Socio-Technological Transformation in a Fluid and Dynamic Digital World

Ongoing digital innovations are transforming almost every aspect of our contemporary societies—rendering our lives and work evermore fluid and dynamic. This paper is an invitation to likewise remake our theorizing of socio-technological transformation by shifting from actor-centric orientations towards a flow-oriented approach and vocabulary. Such a shift from actors to the flows of action allows us to offer an innovative theory of socio-technological transformation that does not rely on self-contained actors or technologies as originators of transformation. Instead, it allows us to foreground how contingent confluences among heterogenous flows of action can account for the trajectories of socio-technological (trans)formation, both upstream and downstream. To do this, we turn to the work of social anthropologist Tim Ingold to advance a theoretical vocabulary of flowing lines of action and their correspondences. We expound three modalities of correspondence, namely: timing, attentionality, and undergoing, which together explain the dynamics of creation, sensing, and actualization of (trans)formative possibilities for action along socio-technological flows. We demonstrate the application and utility of this vocabulary through an empirical illustration and show how it reveals novel insights for IS research vis-a-vis existing theoretical alternatives. Finally, we outline the implications of our approach for IS research and suggest some guiding principles for studying and theorizing IS phenomena through this orientation. We invite the IS community to engage with our approach to develop novel ways of understanding and theorizing IS phenomena along our increasingly fluid and dynamic digital world, ever overflowing.
Implementation of True Random Number Generator Using FPGA Based System

— Cryptographic systems have become an integral part of our daily life through the need of security activities such as communication, electronic money systems, disc encryptions. Random numbers is a key component for strengthening and securing the confidentiality of electronic communications and used in many cryptographic applications like key generation, encryption, masking protocols, internet gambling. Unpredictable random numbers are essential for the security of cryptographic algorithms for generating the underlying secret keys. TRUE random number generators (TRNGs) have become an vital component in many cryptographic systems, including PIN/password generation, authentication protocols, key generation, random padding, and nonce generation. The circuit utilizes undetermined random process, usually in the form of electrical noise, as a basic source. Field programmable gate arrays (FPGAs) form an ideal platform for hardware implementations of many of these security algorithms. Proposed TRNG is based on the principle of beat frequency detection for Xilinx-FPGA-based applications.
On the Robust Stability of 2 D Mixed Continuous-Discrete-Time Systems with Uncertainty Graziano Chesi

This paper addresses the problem of establishing robust exponential stability of 2D mixed continuous-discretetime systems affected by uncertainty. Specifically, it is supposed that the matrices of the system are polynomial functions of an uncertain vector constrained over a semialgebraic set. First, it is shown that robust exponential stability is equivalent to the existence of a complex Lyapunov functions depending polynomially on the uncertain vector and an additional parameter of degree not greater than a known quantity. Second, a condition for establishing robust exponential stability is proposed via convex optimization by exploiting sums-of-squares (SOS) matrix polynomials. This condition is sufficient for any chosen degree of the complex Lyapunov function candidate, and is also necessary for degrees sufficiently large.
A Quasi-periodic Fast-propagating Magnetosonic Wave Associated with the Eruption of a Magnetic Flux Rope

Using high temporal and high spatial resolution observations taken by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory, we present a detailed observational analysis of a high-quality quasi-periodic fast-propagating (QFP) magnetosonic wave that was associated with the eruption of a magnetic flux rope and a GOES C5.0 flare. For the first time, we find that the QFP wave lasted for the entire flare lifetime rather than only during the rising phase of the accompanying flare, as reported in previous studies. In addition, the propagation of the different parts of the wave train showed different kinematics and morphologies. For the southern (northern) part, the speed, duration, and intensity variation are about 875 ± 29 (1485 ± 233) km s−1, 45 (60) minutes, and 4% (2%), and their pronounced periods are 106 ± 12 and 160 ± 18 (75 ± 10 and 120 ± 16) s, respectively. It is interesting that the northern part of the wave train showed an obvious refraction effect when it passed through a region of strong magnetic field. The result of a periodicity analysis indicates that all of the periods of the QFP wave can be found in the period spectrum of the accompanying flare, suggesting their common physical origin. We propose that the quasi-periodic nonlinear magnetohydrodynamics process in the magnetic reconnection that produces the accompanying flare should be important in exciting a QFP wave, and the different magnetic distributions along different paths can account for the different speeds and morphology evolution of the wave fronts.
SURROGATES: Virtual OBUs to Foster 5G Vehicular Services

Virtualization technologies are key enablers of softwarized 5G networks, and their usage in the vehicular domain can provide flexibility and reliability in real deployments, where mobility and processing needs may be an issue. Next-generation vehicular services, such as the ones in the area of urban mobility and, in general, those interconnecting on-board sensors, require continuous data gathering and processing, but current architectures are stratified in two-tier solutions in which data is collected by on-board units (OBU) and sent to cloud servers. In this line, intermediate cache and processing layers are needed in order to cover quasi-ubiquitous data-gathering needs of vehicles in scenarios of smart cities/roads considering vehicles as moving sensors. The SURROGATES solution presented in this paper proposes to virtualize vehicle OBUs and create a novel Multi-Access Edge Computing (MEC) layer with the aim of offloading processing from the vehicle and serving data-access requests. This deals with potential disconnection periods of vehicles, saves radio resources when accessing the physical OBU and improves data processing performance. A proof of concept has been implemented using OpenStack and Open Source MANO to virtualize resources and gather data from in-vehicle sensors, and a final traffic monitoring service has been implemented to validate the proposal. Performance results reveal a speedup of more than 50% in the data request resolution, with consequently great savings of network resources in the wireless segment. Thus, this work opens a novel path regarding the virtualization of end-devices in the Intelligent Transportation Systems (ITS) ecosystem.
Solar-like oscillations and magnetic activity of the slow rotator EK Eridani

Aims. We aim to understand the interplay between non-radial oscillations and stellar magnetic activity and test the feasibility of doing asteroseismology of magnetically active stars. We investigate the active slow rotator EK Eri which is the likely descendant of an Ap star. Methods. We analyze 30 years of photometric time-series data, 3 years of HARPS radial velocity monitoring, and 3 nights of highcadence HARPS asteroseismic data. We construct a high-S /N HARPS spectrum that we use to determine atmospheric parameters and chemical composition. Spectra observed at different rotation phases are analyzed to search for signs of temperature or abundance variations. An upper limit on the projected rotational velocity is derived from very high-resolution CES spectra. Results. We detect oscillations in EK Eri with a frequency of the maximum power of νmax = 320 ± 32 μHz, and we derive a peak amplitude per radial mode of ≈0.15 m s −1 , which is a factor of ≈3 lower than expected. We suggest that the magnetic field may act to suppress low-degree modes. Individual frequencies can not be extracted from the available data. We derive accurate atmospheric parameters, refining our previous analysis, finding Teff = 5135 ± 80 K, log g = 3.39 ± 0.12, and metallicity [M/H] =+ 0.02 ± 0.04. Mass and radius estimates from the seismic analysis are not accurate enough to constrain the position in the HR diagram and the evolutionary state. We confirm that the main light variation is due to cool spots, but that other contributions may need to be taken into account. We tentatively suggest that the rotation period is twice the photometric period, i.e., Prot = 2Pphot = 617.6 d, and that the star is a dipole-dominated oblique rotator viewed close to equator-on. We conclude from our derived parameters that v sini < 0.40 km s −1 and we show that the value is too low to be reliably measured. We also link the time series of direct magnetic field measurements available in the literature to our newly derived photometric ephemeris.
Semantic Segmentation Refinement with Deep Edge Superpixels to Enhance Historical Land Cover

In this work, we explore a post-processing method to enhance coarse semantic segmentation of historical aerial images. We propose to use deep edges to generate semantically meaningful superpixels that we integrate as additional pairwise potentials in a dense conditional random field. We apply our approach on very high resolution images acquired between 1975 and 1995 and annotated with land use land cover labels. Results show the interest of our approach compared to other post-processing methods.
Sharp Operator Based Edge Detection

Ahmad et al. in their paper [1] for the first time proposed to apply sharp function for classification of images. In continuation of their work, in this paper we investigate the use of sharp function as an edge detector through well known diffusion models. Further, we discuss the formulation of weak solution of nonlinear diffusion equation and prove uniqueness of weak solution of nonlinear problem. The anisotropic generalization of sharp operator based diffusion has also been implemented and tested on various types of images.
Cultivation Features Using Meteorological and Satellite Data from 2001 to 2010 in Dakhla Oasis, Egypt

The differences between the oasis region and the regions of the Nile delta and Nile valley in Egypt are due mainly to the regions’ access to water. The oasis region depends on underground water, while the other regions rely on the Nile River. Numerous studies on cultivation in the Nile delta have been accumulated. However, few studies have addressed cultivation in the oasis region. This study examines cultivation throughout the government and local well districts using meteorological and satellite data from 2001 to 2010, and the interview in Rashda Village, Dakhla Oasis. Since the reference evapotranspiration (ET0) is lower in winter than in summer, cultivation in winter makes sense from the viewpoint of saving irrigation water. Evapotranspiration is highest in the order of date palm, rice paddy, winter wheat, and clover hay under sufficient wet conditions in Rashda Village. Cultivation features and water requirements were examined using the Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI). Results indicated a distinct difference in cultivation systems between the summer and winter seasons in the government well district. Water requirements for date palm in the local well district were 2.6 times those for winter plants in the government well district, using the accumulated NDWI value.
Trends in pressure-induced layer-selective half-collapsed tetragonal phases in the iron-based superconductor family 
AeAFe4As4

By performing pressure simulations within density functional theory for the family of iron-based superconductors $Ae{}A$Fe$_4$As$_4$ with $Ae$ = Ca, Sr, Ba and $A$ = K, Rb, Cs we predict in these systems the appearance of two consecutive half-collapsed tetragonal transitions at pressures $P_{c_1}$ and $P_{c_2}$, which have a different character in terms of their effect on the electronic structure. We find that, similarly to previous studies for CaKFe$_4$As$_4$, spin-vortex magnetic fluctuations on the Fe sublattice play a key role for an accurate structure prediction in these materials at zero pressure. We identify clear trends of critical pressures and discuss the relevance of the collapsed phases in connection to magnetism and superconductivity. Finally, the intriguing cases of EuRbFe$_4$As$_4$ and EuCsFe$_4$As$_4$, where Eu magnetism coexists with superconductivity, are discussed as well in the context of half-collapsed phases.
Application of the WetSpa distributed hydrological model for catchment with significant contribution of organic soil. Upper Biebrza case study

Application of the WetSpa distributed hydrological model for catchment with significant contribution of organic soil. Upper Biebrza case study The paper treats on hydrological distributed model adaptation for a catchment with significant contribution of wetland. The WetSpa model was applied to analyzing the effects of topography, soil type, and land use cover on the runoff characteristics for upper Biebrza catchment. The derivation of parameter maps and analysis of the daily runoff as reaction of the catchment on rainfall was performed. The semi-automated calibration of the model was executed using PEST module. Then, the assessment of that crucial processes was done by calculating errors of mathematical models performance as well as hydrograph comparison. Error values, have shown that the model efficiency was estimated to be good for high flows, but unsatisfactory for low flows. This initial modeling approach gives possibility to ask question about limitation and needs of wetland catchment for rainfall-runoff modeling. Zastosownie hydrologicznego modelu o parametrach rozłożonych WetSpa w zlewni o znaczącym udziale gleb organicznych, na przykładzie górnej Biebrzy Artykuł dotyczy adaptacji modelu hydrologicznego o parametrach rozłożonych w zlewni o znaczącym udziale gleb organicznych. Zastosowany model WetSpa umożliwił dokonanie analizy wpływu topografii, rodzaju gleb i użytkowania terenu na charakterystyki odpływu w zlewni górnej Biebrzy. W pierwszym etapie określono parametry przestrzenne w postaci map, a następnie obliczano dobowy odpływ jako reakcję zlewni na opad. Do kalibracji wykorzystano procedurę półautomatyczną, stosując program PEST. Następnie przeprowadzono ocenę najważniejszych procesów, obliczając błędy modelowania matematycznego oraz porównując hydrogramy odpływu. Wielkości błędów pokazały wysoką skuteczność modelu w przypadku symulacji przepływów wysokich, lecz niesatysfakcjonujące wyniki w obliczaniu przepływów niskich. Ta wstępna analiza dała możliwość zadania pytan o granice i potrzeby w modelowaniu opad-odpływ na obszarach mokradłowych.
A Process Model of Building Sustainable Competitive Advantage for Multinational Enterprises: An Empirical Case Study Model procesu budowania zrównoważonej przewagi konkurencyjnej dla przedsiębiorstw międzynarodowych: studium przypadku

Multinational enterprises (MNEs) are the leading entities in the process of global economic integration, whose international expansion would be regulated and constrained by environmental issues. Drawing on theories of corporate social responsibility, corporate environmental behavior and legitimacy, this paper establishes a grounded process model that has both theoretical and practical significance. The model reveals that development of sustainable competitive advantage of MNEs is a gradual process that is dependent on the corporate environmental behavior and the legitimation of their behaviors. Via a real in-depth case study of Badische Anilin-Soda-Fabrik (BASF), one of the largest chemical companies in the world, the application and effectiveness of the proposed process model are demonstrated. Also, implications of this model and future directions for both research and practice are indicated.
Merced Proceedings of the Annual Meeting of the Cognitive Science Society Title The Effect of Incremental Context on Conceptual Processing : Evidence from Visual World and Reading Experiments

The analysis of the internal structure of concepts reveals the presence of a substantial amount of contextual information. Even though this interaction is easily recognizable, it is not clear how contextual information is processed and included into concept representations. The aim of this paper is to shed light on this question by analyzing the effect that an increasing amount of context exerts on conceptual processing. We report a self-paced reading experiment and a visual world experiment to test two hypotheses about the integration of context information: the incremental activation hypothesis suggests that the degree of facilitation in concept processing increases with the amount of context available; and the immediate activation hypothesis states that once a sufficient amount of contextual support is reached, no more facilitation occurs. Our data are compatible with the latter account.
A neuroanatomical approach to improving organizational performance

Insights gained from studying the human brain have begun to open up promising new areas of research in the behavioural and social sciences. Neuroscience-based principles have been incorporated into areas such as business management, economics and marketing, leading to the development of artificial neural networks, neuroeconomics, neuromarketing and, most recently, organizational cognitive neuroscience. Similarly, the brain has been used as a powerful metaphor for thinking about and analysing the nature of organizations. However, no existing approach to organizational analysis has taken advantage of contemporary neuroanatomical principles, thereby missing the opportunity to translate core neuroanatomical knowledge into other, non-related areas of research. In this essentially conceptual paper, we propose several ways in which neuroanatomical approaches could be used to enhance organizational theory, practice and research. We suggest that truly interdisciplinary and collaborative research between neuroanatomists and organizational analysts is likely to provide novel approaches to exploring and improving organizational performance.

VARIATION IN TOTAL POLYPHENOL CONTENT, ANTIOXIDANT POTENTIAL, THEAFLAVIN AND THEARUBIGINS CONTENT OF BOPF GRADE SRI LANKAN BLACK TEAS (Camellia sinensis L.) OF DIFFERENT CLIMATIC ELEVATIONS AND BOPF GRADE COMMERCIALLY AVAILABLE BLACK TEAS IN SRI LANKA

Black tea is the most popular tea among three major types of tea namely green, oolong and black tea. Unblended Sri Lankan black teas are classified as high grown, medium grown and low grown based on their geographical origin. However some studies have been reported regarding the chemical parameters of black teas from different agro climatic elevations of Sri Lanka, such details like purity, cultivar and the particle size of teas have not been specified. And also there is no systematic screening has been reported for black tea commercialized in Sri Lankan market. So the main objective of this study was to analyze the total polyphenol content, antioxidant activity & total thearubigins & theaflavins content in unblended Sri Lankan black teas collected from factories representing different tea growing regions. And also to analyze the same biochemical parameters for the black teas that are commercialized in Sri Lankan market. During the month of April 2012, BOPF grade fermented black tea samples produced by TRI 2025 were collected from twelve tea plantations of different agro climatic elevations. All the teas were processed according to the orthodox-rotor vane method. Ten commercialized samples of different brands were also analyzed. Total phenolic content (ISO 14502-1 method), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging activity, TF (flavognost method) and TR content were determined for each sample. Mid grown tea showed highest mean values in TPP content (15.9454 ± 2.5778 % GAE), TF content (22.2200 ± 3.9575 μmol/g) and TR content (14.6031 ± 1.8970 %). The antioxidant activity was well correlated with the total polyphenol content (P < 0.05) and thearubigins contents (P < 0.05). Lowest mean EC50 value (49.6791 ± 5.9475 μg/ml) was obtained by mid grown tea samples, indicating highest antioxidant activity among others. Rilagala plantation showed the maximum values in TPP content, antioxidant activity, TF and TR contents among others.
