Community Structure of a Molluscan Assemblage in an Anthropized Environment , Hammamet Marina , North-Eastern Tunisia

Hammamet Marina is the most important touristic port in the Gulf of Hammamet (Tunisia). The present work is a contribution to the knowledge of the functional diversity and structure of the malacofauna community in this area. Three different stations (A, B and C) within the port were sampled seasonally for a year (2005-2006). The mollusc assemblage studied was represented by 14 species (in totally 2669 ind. were found). Among the four mollusc classes recorded, bivalves were the best represented (73.76% of the total number species), followed by gastropods (22.02%), cephalopods (2.42%) and polyplacophores (1.80%). Atlanto-Mediterranean (42.85%) and Endemic Mediterranean (39.28%) taxa prevailed in the community, followed by Indo-Pacific (7.14%) and cosmopolitan species (3.57%). A clear spatial zonation was distinguished. The station B hosted the highest abundance of gastropods (309±19.92 ind. m) and a species richness of 6±0.40. The station station A hosted the most equilibrated trophic structure, with a higher bivalve abundance (1378±99.23 ind. m) and a species richness of 6±0.1. Station C, located close to the mooring boats, presented the lowest abundance (230±17.47 individuals m) and the most affected assemblage. This station seemed to be affected by the higher anthropogenic pressure assessed compared to the other two stations, mainly oil pollution, due to the large quantities of hydrocarbon discharged from the boats.
Piezo acoustic versus opto-acoustic sensors in laser processing

Piezo acoustic sensors are well known in the field of acoustic emission since the 20’s but are considered as a common product since the 70’s. Since that time, the number, type, shape and temperature range of AE sensors have been broaden to satisfy the industrial demands. When considering either high temperature and/or small size, piezo acoustic sensors have limits and an alternative technology has to be considered. In industrial applications with special requirements to high temperature tolerance, small size (< 150 μm), broad frequency response, insensitive to electromagnetic interference, opto-acoustic sensors including Fibre Bragg Grating (FBG) are very good candidates. FBG is an interferometric structure, imprinted inside the core of the optical fibre with unique spectral characteristics of reflectivity. The acoustic waves created during an industrial process result in periodical extension/compression of the optical fibre core and, consequently, the FBG structure. These momentary deformations affect the reflectivity properties of the FBG that follow the behaviour of the incoming pressure waves. This behaviour results in the intensity of the reflected light that encodes the momentary deformation states of the fibre core and so can be used for acoustic sensing. These sensors exhibit linear response in a broadband frequency range (from several Hz to tens of MHz) with potential detection upper limit of the order of several hundred MHz. In contrast, most piezo sensors have linear response in a limited bandwidth and lower detectable frequencies. In this work, we will focus on the fibre technology and compare the sensitivity of commercial FBG with several piezo acoustic sensors. We will also show how FBG’s can be used as acoustic sensors in laser processing by analysing the data with state-of-the-art machine learning techniques, in particular for classification of laser power made from the sample itself which can be related to its quality.
Perspectives of Earnings Management In Islamic Banking Institutions

This paper examines whether executives in Islamic banking institutions (IBIs) are more likely to use efficient earnings management (EM) or opportunistic EM. A sample of 81 Islamic banks in a 10 year financial period from 2000 to 2009 has been analyzed and fixed effect regression method is applied. We found a positive and significant relationship between EM proxy and future profitability, which means that EM tends toward efficient. This indicates that Islamic banks executives do not use their discretion to opportunistically manipulate their earnings. But they use their discretion to communicate inside information about IBIs profitability.Furthermore, this paper provides indirect evidence that Islamic ethical standards affect the likelihood of unethical opportunistic EM. Islamic ethics, it is established, prohibit such managerial behaviour as it violates the Islamic ethical axioms.
BIOFUELS FOR DIESEL ENGINES IN THE CZECH REPUBLIC

The paper addresses diesel engine fuel components made of biomass, i.e. bioethanol and biodiesel. It focuses on the biofuels‘ characteristics, the conditions and potential for their use for diesel engines, and the impact of biofuels on engine exhaust emissions. The work briefly summarizes the history of biofuels in the Czech Republic and their anticipated future usage so as to comply with the current expectations of the European Commission respecting the gradual substitution of oil-based engine fuels with alternative ones.
Hiding in Plain Strokes : Handwriting and Applications to Steganography

Steganography, the process of hiding secret information within normal-looking data (a cover), lies at the intersection of computer science and security. Recently, covers have come in the form of images [2]. Standard methods consider fully saturated (dense) images, which simplifies the encoding and decoding tasks. First, slight modifications of pixel intensities (needed to encode a message) are imperceptible when the image is dense, but easy to detect if an image is sparse (e.g. text on a plain white background). Further, if the message being encoded is dense too (e.g. also an image), slight decoding mistakes are not important, because a human viewer can still correctly perceive the meaning. We consider a complementary and more challenging scenario: encoding a sparse message into a sparse cover. We consider a sequence of handwriting strokes as the cover, and embed a secret message by altering each coordinate in the cover, rather than superimposing a new signal (message). The stages of our approach are as follows. First, the secret information is encrypted before combining it with the cover using neural cryptography. Second, the information is hidden in the stroke data of a person’s handwriting on a white background. We utilize coordinate sequences of human handwriting, modified with slight offsets dependent on the secret information being encoded. The new generated coordinates are nearly identical to the original ones, preserving the primary structure of the handwriting. Our method thus explores a new avenue of steganography based on data modification rather than embedding.
GROWTH INDICES AND NUTRIENT UPTAKE OF FODDER MAIZE ( ZEA MAYS L . ) AS INFLUENCED BY INTEGRATED NUTRIENT MANAGEMENT

A field experiment was conducted at Research Farm Area of Forage Section, Department of Genetics & Plant Breeding, CCS Haryana Agricultural University, Hisar during kharif 2010. The experiment was carried out in randomized block design with ten treatments viz., Control, seed treatment with Azotobacter, 100 per cent N through FYM, 100 per cent RDF, 75 per cent RDF+Azotobacter, 75 per cent RDF+25 per cent N through FYM, 75 per cent RDF+25 per cent N through FYM+Azotobacter, 50 per cent RDF+Azotobacter, 50 per cent RDF+50 per cent N through FYM and 50 per cent RDF+50 per cent N through FYM+Azotobacter. The growth indices Leaf Area Index and crop growth rate were observed significantly higher with 100 per cent RDF followed by 75 per cent RDF+25 per cent N through FYM+Azotobacter. Availability of N, P and K in the soil under most of the treatments decreased after the crop harvest than before the sowing of the crop. The highest NPK status in the soil after the harvest of crop was recorded in the treatment 100 per cent N through FYM.

Exotic chicken production performance, status and challenges in Ethiopia

Poultry is the largest group of livestock species in the world in which chickens largely dominate the fl ock composition. The poultry sector in Ethiopia can be characterized into three major production systems based on selected parameters like breed, fl ock size, housing, feeding, health, technology, biosecurity and others. These are large scale commercial, small scale commercial and village poultry production systems.
Cannabis and psychotic experiences 1 Psychotic experiences are linked to cannabis use in adolescents in the community because of common underlying environmental risk factors

Cannabis users are more likely to have psychotic experiences (PEs). The degree to which these associations are driven by genetic or environmental influences in adolescence is unknown. This study estimated the genetic and environmental contributions to the relationship between cannabis use and PEs. Specific PEs were measured in a community-based twin sample (4,830 16-year-old pairs) using self-reports and parent-reports. Adolescents reported on ever using cannabis. Multivariate liability threshold structural equation model-fitting was conducted. Cannabis use was significantly correlated with PEs. Modest heritability (37%), common environmental influences (55%) and unique environment (8%) were found for cannabis use. For PEs, modest heritability (2754%), unique environmental influences (E= 12-50%) and little common environmental influences (11-20%), with the exception of parent-rated Negative Symptoms (42%), were reported. Environmental influences explained all of the covariation between cannabis use and paranoia, cognitive disorganization and parent-rated negative symptoms (bivariate common environment = 69-100%, bivariate unique environment = 28-31%), whilst the relationship between cannabis use and hallucinations indicated familial influences. Cannabis use explains 2-5% of variance in positive, cognitive, and negative PEs. Cannabis use and psychotic experience co-occur due to environmental factors. Focus on specific environments may reveal why adolescent cannabis use and psychotic experiences tend to ‘travel together’.
Multiobjective Evolutionary Map Design for Cube 2: Sauerbraten

Map design is a major challenge in the development of a successful multiplayer first-person shooter. In fact, it has a large impact on the game dynamics and deeply affects the player experience. In this paper, we present a search-based procedural content generation approach to the map design problem in Cube 2: Sauerbraten, an open-source first-person shooter. Extending previous works introduced in the literature, we propose several design objectives to evaluate the maps as well as a novel methodology to compute them. To test our approach, we designed two different design problems that require to deal with conflicting objectives (i.e., balancing, pacing, and achievement of long kill streaks) and with players using different playing styles. The results are promising as they show that our approach, exploiting multiobjective evolution, is able to explore effectively the map design space and to provide maps that feature interesting tradeoffs between the conflicting objectives.
UDPipe at SIGMORPHON 2019: Contextualized Embeddings, Regularization with Morphological Categories, Corpora Merging

We present our contribution to the SIGMORPHON 2019 Shared Task: Crosslinguality and Context in Morphology, Task 2: contextual morphological analysis and lemmatization. We submitted a modification of the UDPipe 2.0, one of best-performing systems of the CoNLL 2018 Shared Task: Multilingual Parsing from Raw Text to Universal Dependencies and an overall winner of the The 2018 Shared Task on Extrinsic Parser Evaluation. As our first improvement, we use the pretrained contextualized embeddings (BERT) as additional inputs to the network; secondly, we use individual morphological features as regularization; and finally, we merge the selected corpora of the same language. In the lemmatization task, our system exceeds all the submitted systems by a wide margin with lemmatization accuracy 95.78 (second best was 95.00, third 94.46). In the morphological analysis, our system placed tightly second: our morphological analysis accuracy was 93.19, the winning system’s 93.23.
A Comparison of Radial and Linear Charts for Visualizing Daily Patterns

Radial charts are generally considered less effective than linear charts. Perhaps the only exception is in visualizing periodical time-dependent data, which is believed to be naturally supported by the radial layout. It has been demonstrated that the drawbacks of radial charts outweigh the benefits of this natural mapping. Visualization of daily patterns, as a special case, has not been systematically evaluated using radial charts. In contrast to yearly or weekly recurrent trends, the analysis of daily patterns on a radial chart may benefit from our trained skill on reading radial clocks that are ubiquitous in our culture. In a crowd-sourced experiment with 92 non-expert users, we evaluated the accuracy, efficiency, and subjective ratings of radial and linear charts for visualizing daily traffic accident patterns. We systematically compared juxtaposed 12-hours variants and single 24-hours variants for both layouts in four low-level tasks and one high-level interpretation task. Our results show that over all tasks, the most elementary 24-hours linear bar chart is most accurate and efficient and is also preferred by the users. This provides strong evidence for the use of linear layouts – even for visualizing periodical daily patterns.

Fault-Tolerant Routing in Mesh-Connected Multicomputers based on Majority-Operator-Produced Transfer Direction Identifiers

The paper focuses on fault-tolerant 2D mesh-connected multicomputers, which can proceed operating even if some of their units and/or links are faulty, and more particularly, on the routing environment of the multicomputers capable of transferring packets between healthy processor units along the paths containing faulty components. A novel approach to the fault-tolerant packet routing is presented making it possible to increase the packet delivery probability by expanding the XY-routing scheme. The proposed approach is capable of recovering corrupted routing direction data contained in the address section of a packet by using the majority operator applied to the current direction IDs generated at the current and the two preceding hops on the route. Our simulation study shows that the successful routing probability increases at least by 40% with the new scheme; yet, it grows on as the route length increases compared to the XY-routing with no routing data recovery. Keywords— Fault-tolerance, Mesh-connected multicomputers, Packet routing, Reliability.
Evaluation of Slip Effects in the Capillary Flow of Foams

Abstract Foams have been prepared from water added with a surfactant (Sodium-Dodecyl-Sulfate, SDS) and a polymer (Poly-Ethylene-Oxide, PEO) at different concentrations. This work was devoted to a study of the flow properties of the foams. The pressure drops were measured during flow in capillary tubes (2.5, 3.5 and 4 mm) in laminar regime. It was found a strong dependence of the flow curves on capillary diameter showing that pronounced wall slip effects exist. Two known approaches were applied to quantify the slip velocity: (a) the Mooney method, in which the key assumption is that the slip velocity depends only on the wall shear stress, was not applicable and (b) the Oldroyd-Jastrzebski method, in which the assumption is that the slip velocity depends not only on the wall shear stress but also on the flow geometry, yielded satisfactory results. The determination of the pressure drop coefficient showed that the Metzner and Reed correlation, i.e., the Reynolds analogy based on the generalised Reynolds number, could be applied if the data are corrected for slip effects.
Serological inference of past primary and secondary dengue infection: implications for vaccination

Owing to the finding that Dengvaxia® (the only licensed dengue vaccine to date) increases the risk of severe illness among seronegative recipients, the World Health Organization has recommended screening individuals for their serostatus prior to vaccination. To decide whether and how to carry out screening, it is necessary to estimate the transmission intensity of dengue and to understand the performance of the screening method. In this study, we inferred the annual force of infection (FOI; a measurement of transmission intensity) of dengue virus in three locations in Vietnam: An Giang (FOI = 0.04 for the below 10 years age group and FOI = 0.20 for the above 10 years age group), Ho Chi Minh City (FOI = 0.12) and Quang Ngai (FOI = 0.05). In addition, we show that using a quantitative approach to immunoglobulin G (IgG) levels (measured by indirect enzyme-linked immunosorbent assays) can help to distinguish individuals with primary exposures (primary seropositive) from those with secondary exposures (secondary seropositive). We found that primary-seropositive individuals—the main targets of the vaccine—tend to have a lower IgG level, and, thus, they have a higher chance of being misclassified as seronegative than secondary-seropositive cases. However, screening performance can be improved by incorporating patient age and transmission intensity into the interpretation of IgG levels.
GENERAL MORPHOLOGY AND RELATION BETWEEN POTASSIUM AND POLLEN IN JAPANESE ANGELICA (ARALIA ELATA L.)

Japanese angelica (Aralia elata L.) pollens were collected from the mature central open spikelet having visible anthers and were used for morphological observation. Scanning electron microscope revealed two distinctive types of pollen. One was comparatively larger in size and regular in shape (fertile) while the other was smaller and irregular in shape (sterile). Scanning electron microscope showed that pollen has clearly visible four apertures. It was hypothesized that potassium (K) may be involved in pollen swelling and the mechanisms underlying the rapid imbibition of water. Scanning electron microscopy with EDX (Energy dispersive X-ray) attachment was used to observe K at aperture area of pollen. It was found the K intensity were higher when the beam was passed through the aperture whereas intensity of K peaks reduced when the beam passed through the area that is between apertures. These results support our hypothesis that if K drives rapid imbibition of water then it should be located in the aperture area of pollen. These results demonstrate that a likely relationship exists between K located at the aperture and the swelling of pollen.
Interdisciplinary optimism? Sentiment analysis of Twitter data

Interdisciplinary research has faced many challenges, including institutional, cultural and practical ones, while it has also been reported as a ‘career risk’ and even ‘career suicide’ for researchers pursuing such an education and approach. Yet, the propagation of challenges and risks can easily lead to a feeling of anxiety and disempowerment in researchers, which we think is counterproductive to improving interdisciplinarity in practice. Therefore, in the search of ‘bright spots’, which are examples of cases in which people have had positive experiences with interdisciplinarity, this study assesses the perceptions of researchers on interdisciplinarity on the social media platform Twitter. The results of this study show researchers’ many positive experiences and successes of interdisciplinarity, and, as such, document examples of bright spots. These bright spots can give reason for optimistic thinking, which can potentially have many benefits for researchers’ well-being, creativity and innovation, and may also inspire and empower researchers to strive for and pursue interdisciplinarity in the future.
Unusual echolocation behaviour of the common sword-nosed bat Lonchorhina aurita: an adaptation to aerial insectivory in a phyllostomid bat?

Most insectivorous bat species in the Neotropical family Phyllostomidae glean insects from ground, water or vegetation surfaces. They use similar and stereotypical echolocation calls that are generally very short (less than 1–3 ms), multi-harmonic and frequency-modulated (FM). By contrast, the common sword-nosed bat, Lonchorhina aurita, which has the longest noseleaf in the entire phyllostomid family, produces distinctly different echolocation calls. They are composed of a constant frequency (CF) component with a peak frequency of 45 kHz, followed by a short FM down-sweep at the end. With a mean call duration of 6.6 ms (max. 8.7 ms) when flying in the open they have the longest echolocation calls reported from phyllostomid bats. In cluttered environments, the CF-component is very short. In open habitats, however, L. aurita can emit pure CF-calls without the terminal FM-component. We also recorded in the field a distinct terminal group that closely resembles the feeding buzzes of aerial hawking bat species from other bat families. This is the first time the echolocation call design of L. aurita is presented. In addition, we contrast the echolocation behaviour of individuals flying in open and confined situations. Our results suggest that the unique echolocation system of L. aurita represents an adaptation to aerial hawking, a very unusual hunting mode within the phyllostomid family.
Antibody-Directed Therapies: Toward a Durable and Tolerable Treatment Platform for CTCL

Cutaneous T-cell lymphomas (CTCL) are a rare group of heterogeneous disorders characterized by cutaneous involvement of monoclonal T-lymphocytes. Although indolent at early stages, CTCL can confer significant morbidity, and mortality when advanced. There is an unmet need for tolerable and durable treatments with antibodies recently gaining promise. Here we review approved systemic therapies and discuss select antibodies in development.
