Detection and identification of cyanobacteria associated with toxic blooms: DNA amplification protocols

Abstract The cyanobacteria include the oldest dated life forms on Earth. Previously, and still commonly, known as blue-green algae, the cyanobacterial division is immensely diverse, with respect to form and habitat. This has made taxonomic evaluation particularly difficult. Classification is currently based on differences in morphological characters. Greater certainty in identification of separate taxa may be achieved by direct analysis of the genome. The study of microbial ecology and evolution has been greatly facilitated by the introduction of rapid methods for DNA amplification and sequence analysis. We have applied several traditional and novel molecular methods to the study of cyanobacterial systematics and phylogeny. The presented methods have been investigated with respect to their applicability for both inter- and intrageneric classification. The utility of each protocol is reviewed, and an integrated approach to the detection and identification of cyanobacterial taxa is suggested. The polymerase.

Reproductive performance and nest-site selection of White-naped Cranes Grus vipio in the Ulz river valley, north-eastern Mongolia

North-eastern Mongolia is an important breeding area for the globally threatened White-naped Crane Grus vipio. We studied reproductive performance and the influence of factors related to livestock grazing on reproduction and nest-site selection of the White-naped Crane population in the Ulz river valley, north-eastern Mongolia in 2000 and 2001. In 2001, 42 territorial pairs were found in 270 km of river basin. Recruitment was 18–22% resulting in 0.5–0.6 juveniles per territorial pair. The years 2000 and 2001 were within a dry period and recruitment might have been below the long-term average. White-naped Crane nests were significantly associated with river basin sections containing shallow water-bodies. The number and extent of shallow water-bodies are likely to be a limiting factor for breeding population size. Nest-sites in water-bodies were selected for high nest concealment, but nests were initiated even when concealing vegetation was not available. Only 26% of nests were >90% concealed suggesting that appropriate cover was often not available. Nest-sites were also selected for low grazing intensity. No correlation was found between hatching or fledging success and nest concealment or grazing intensity. Brood-size of successful pairs was higher if the home range was ungrazed, but further investigations are needed to clarify whether this was caused by absence of livestock grazing or other factors. Both because of internationally important numbers and because of a potentially high reproductive output, the study area is of high importance for the species.
Detection of Militia Object in Libya by Using YOLO Transfer Learning

Humans can recognize and classify shapes, names, and provide responses to object that are received by visually quickly and accurately. More importantly, it is expected that the system created is able to help provide response in all tasks and time, for example when driving, walking in the crowd even when patrolling as a member of the military on dangerous terrain.This has become a problem in the system used on the battlefield. In the proposed system, the object detection model must be able to sort out the objects of armed humans (militia) with unarmed human objects. To overcome the problem the author uses the YOLO transfer learning algorithm which currently has the third version. It is stated that YOLOv3 has very extreme speed and accuracy. In mean Average Precision (mAP) obtained by 0.5 IOU, YOLOv3 is equivalent to 4x faster than Focal Loss. Moreover, YOLOv3 also offers optimal speed and accuracy simply by changing the size of the model, without the need for retraining. DOI: https://doi.org/10.26905/jtmi.v6i1. 4025
An Attention-Based Unsupervised Adversarial Model for Movie Review Spam Detection

With the prevalence of the Internet, online reviews have become a valuable information resource for people. However, the authenticity of online reviews remains a concern, and deceptive reviews have become one of the most urgent network security problems to be solved. Review spams will mislead users into making suboptimal choices and inflict their trust in online reviews. Most existing research manually extracted features and labeled training samples, which are usually complicated and time-consuming. This paper focuses primarily on a neglected emerging domain - movie review, and develops a novel unsupervised spam detection model with an attention mechanism. By extracting the statistical features of reviews, it is revealed that users will express their sentiments on different aspects of movies in reviews. An attention mechanism is introduced in the review embedding, and the conditional generative adversarial network is exploited to learn users’ review style for different genres of movies. The proposed model is evaluated on movie reviews crawled from Douban, a Chinese online community where people could express their feelings about movies. The experimental results demonstrate the superior performance of the proposed approach.
Producing newsgames beyond boundaries: Journalists, game developers, and the news business

Creating successful newsgames requires effective boundary work between journalists and game developers. Both groups come to the job with different professional vocabularies, technical know-how, and work cultures. Our goal was to understand how they approach these challenges as they create a product that satisfies their professional expectations and the demands of media organizations and audiences. This article presents the results of semistructured expert interviews with pioneers in German newsgame production. We found that effective newsgame creation entailed complex coordination efforts. However, expected clashes between the different professional cultures did not occur. Conflicts were eased by a general agreement on news as a public service and by emphasizing nonhierarchical decision-making in teams. Our interviews detail the economic and technical obstacles that have resulted in newsgames not making major inroads. The decline of newsgames was related to the development of other digital media forms that matched journalistic conventions more closely. These findings led us to extend the model of journalistic boundary work to a more interactional concept that highlights the contributions of both sides while acknowledging the obstacles of operating in a larger media system.
Predicting the toxicity of major ions in seawater to mysid shrimp (Mysidopsis bahia), sheepshead minnow (Cyprinodon variegatus), and inland silverside minnow (Menidia beryllina)

Although marine organisms are naturally adapted to salinities well above those of freshwater, elevated concentrations of specific ions have been shown to cause adverse effects on some saltwater species. Because some ions are also physiologically essential, a deficiency of these ions can also cause significant effects. To provide a predictive tool to assess toxicity associated with major ions, mysid shrimp (Mysidopsis bahia), sheepshead minnows (Cyprinodon variegatus), and inland silverside minnows (Menidia beryllina) were exposed to saline solutions containing calcium, magnesium, potassium, strontium, bicarbonate, borate, bromide, and sulfate at concentrations above and below what would be found in seawater. Solution salinity was maintained at approximately 31‰ by increasing or decreasing sodium and chloride concentrations. Logistic regression models were developed with both the ion molar concentrations and ion activity. Toxicity to all three species was observed when either a deficiency or an excess of potassium and calcium occurred. Significant mortality occurred in all species when exposed to excess concentrations of magnesium, bicarbonate, and borate. The response to the remaining ions varied with species. Sheepshead minnows were the most tolerant of both deficient and elevated levels of the different ions. Mysid shrimp and inland silverside minnows demonstrated similar sensitivities to several ions, but silverside minnow response was more variable. As a result, the logistic models that predict inland silverside minnow survival generally were less robust than for the other two species.
Business Model Innovation Approaches: A Systematic Literature Review

The goal of this paper is to evaluate the current academic approaches in the field of business model innovation. By conducting a systematic literature review, 31 academic approaches are identified and compared using the dimensions of business model and process model. In addition, the research concentrates on organizational mindset and to what extend it is considered in current approaches. Among other findings, the research proves that all analyzed studies vary in terms of focus, level of detail and content in the perspectives of business and process model. In particular, organizational mindset is mentioned in four out of the 31 studies as an important success factor of business model innovation, whereas only one approach is dealing with organizational mindset in its process model. This indicates that overcoming the organizational mindset as a main barrier in business model innovation is not systematically integrated in any of the selected studies. In summary, the findings of this paper highlight that the current research in the field of business model innovation is not sufficient and further research has to follow. Thus, three research gaps are identified. First, the lack of level of detail concerning business and process model. Secondly, the lack of business innovation approaches for specific industries. Finally, the lack of systematic integration of organizational mindset in business model innovation approaches.
An Improved Pre-Net Network and Its Application in Material Modeling

Material modeling is a hot issue in the research and application of graphics. The purpose is to determine the properties of material appearance such as texture, normal, reflectivity and roughness through modeling, so as to improve the realism of object rendering. In order to solve the problem of traditional material modeling, it takes a lot of manpower, resources and time. Based on the pre-net proposed by Xiao Li [1], this paper studied the over-fitting and prediction accuracy
A Temperature-Domain SEBAL Model Based on a Wind Speed-Independent Theoretical Trapezoidal Space Between Fractional Vegetation Coverage and Land Surface Temperature

The surface energy balance algorithm for land (SEBAL) model is one of the most widely used methods for estimating evapotranspiration. Numerous physical studies have conducted to mitigate the limitations of spatial-domain dependence and the annoying uncertainties in visually identifying the dry/wet pixels in SEBAL; however, they are subject to the quality of wind speed (<inline-formula> <tex-math notation="LaTeX">${u}$ </tex-math></inline-formula>) observation, which is known as a high temporal–spatial variation and is not routinely available, especially in a heterogeneous area. In this study, we constructed a <inline-formula> <tex-math notation="LaTeX">${u}$ </tex-math></inline-formula>-independent algorithm to calculate the dry/wet endpoints for each pixel. The wet endpoint was determined by assuming no turbulent heat exchange between a water-saturated surface and atmosphere. The dry endpoint was calculated using the assumption and consensus that pixels had equivalent neutral aerodynamic resistance under given atmospheric forcing and vegetation coverage. Then, we built a temperature-domain SEBAL (TD-SEBAL) model and validated it in the MUSOEXE between May and September 2012, located at desert-oasis transition zone in the middle reaches of the Heihe watershed across eight landscapes. The results showed that TD-SEBAL could provide reasonable dry/wet endpoint retrieval, and reliable latent heat flux estimates with a mean bias of −0.25 W/m<sup>2</sup>, a root-mean-square error of 52.9 W/m<sup>2</sup>, and a coefficient of determination of 0.91.
Sipunculans and echiurans from the deep Angola Basin

Sipunculans and echiurans collected by the “DIVA 1” expedition by RV Meteor (Cruise M48/1) to the deep‐sea bottom of the Angola Basin are recorded. Seven species from five genera and two separate phyla are recognized; only the echiuran Pseudoikedella achaeta has not been recorded hitherto in the southern sector of the Atlantic Ocean. A gradient analysis using redundancy analysis (RDA) under the CANOCO package indicates the existence of a neat latitudinal gradient of sipunculans along the Angola Basin from the southernmost stations towards the northern ones. The local abundance of abandoned horny tubes of polychaetes at some of the sampling sites of the northernmost stations explains the dense aggregations of Nephasoma diaphanes. This species exhibits an opportunistic lifestyle inside empty polychaete tubes on the abyssal plains of the Angola Basin.
Growth and recession of aquatic macrophytes on an unshaded section of the River Lambourn, England, from 1971 to 1976

SUMMARY. The growth and recession of the macrophytes on an unshaded section of the R. Lambourn was documented by a mapping procedure from March 1971 to December 1976. The seasonal patterns were determined mainly by the dominant macrophytes. Ranunculus penicillatus var. calcareus and Ranunculus peltatus. Ranunculus grew rapidly in spring and early summer, mainly colonizing areas of gravel and reached a summer maximum. The greatest loss of plants was in August and September but losses continued through the winter to give minimum cover in March. Berula and Callitriche did not show regular seasonal growth patterns but their growth was largely confined to times when there was little growth of Ranunculus. Increase in area of Ranunculus in the spring was positively correlated with the mean discharge at that time. The growth of Ranunculus appeared to be restricted when shading was caused by turbid water due to dredging or by accumulation of epiphytic algae on the surface of the plants in years when discharge was low. Discharge also influenced the substrata underlying Ranunculus and the area of silt under Ranunculus beds was negatively correlated with discharge. The factors thought to influence growth of Ranunculus were used to develop a conceptual model of growth.
It’s a match (?): Tinder usage and attitudes toward interracial dating

ABSTRACT The increased popularity of dating apps such as Tinder coupled with the rise in interracial marriages form the foundation of this study which explores the role played by visual and cultural cues in people’s dating decisions. Using a within-group 2*3 experimental design (N = 331) among a convenience sample of adults in the Netherlands, this study provides insight into how the ethnicity associated with profile pictures and names impact the evaluation of a potential date on Tinder. Overall, respondents ranked Caucasian-looking Tinder users as more attractive and more likely to be their date of choice. Interestingly, this finding did not hold when narrowed down to respondents identifying as Western-European only: They did not prefer Caucasian-looking or sounding profiles. Perceived attractiveness was shown to partially mediate the choice of a Caucasian-looking profile, regardless of name.
Resonance-Based Optimized Buck LED Driver Using Unequal Turn Ratio Coupled Inductance

Losses in light-emitting-diode (LED) driver cause increasing temperature and shorten their lifespan. Therefore, improving the efficiency of LED drivers not only saves energy but also is indispensable to increase their lifespan. In this article, a new LED driver topology is proposed to improve the performance of valley switching by decreasing the mosfet switching losses. The proposed topology is designed in a way that the mosfet works at the significantly lower switching and conduction losses in compared with conventional LED drivers. It elaborates how the proposed topology also improves the overall efficiency by decreasing power losses in other main elements of the driver, including inductance and diode. In addition, a new valley switching implementation is introduced for the new converter, which decreases the cost and dimension of the LED drivers. The experimental results confirm the high efficient operation of the proposed LED driver by reaching the efficiency up to 97% at a wide range of operating voltage.
Seasonal variation in reproductive traits in Ipomopsis longiflora (Polemoniaceae), a desert annual

Seasonal variation in reproductive traits is commonly documented in flowering plants. This variation is critical because it is the material for evolution by natural selection. Understanding the mechanisms that maintain that variation is important, because it can tell us about the ecological and evolutionary forces acting on populations. Using Ipomopsis longiflora (Torr.) V. Grant subsp. australis, a Chihuahuan desert annual that has two discrete flowering seasons, I studied the relative influence of seasonality, variation in the individuals present in the population, and prior reproduction on reproductive traits. I found that traits that represent the allocation of resources within a plant (ovule number, flower number, and flower size) were influenced by seasonality and the individuals present in the population, whereas traits that represent the efficiency of reproduction (seeds/ovule, fruits/flower, and seeds/fruit) were influenced only by seasonality.Key words: iteroparity, semelparity, efficiency, phen.
Trajectory Prediction and Channel Monitoring Aided Fast Beam Tracking Scheme at Unlicensed mmWave Bands

Unlicensed 60 GHz millimeter band has a great potential in industrial Internet of things (IIoT) owing to its continuous large bandwidth. However, the signal transmission in this band suffers from high propagation loss, thus beamforming is adopted to provide directional gain. With the increasing number of beams, beam alignment and tracking in mobility scenario may incur unacceptable latency and overhead, and the existing beam management mechanism is no longer suitable. To reduce the latency and signaling overhead during beam tracking, we propose a fast beam tracking scheme with the help of trajectory prediction and channel monitoring. More specifically, we firstly quantify the beam coherent time to reduce the frequency of beam searching. Then, a two-stage heuristic trajectory prediction and channel monitoring aided fast beam tracking scheme is proposed to obtain the optimal beam pairs in the process of terminal movement and make sure that the interference on the directional beam is under the limit. Simulation results verify the effectiveness of the beam coherent time and the advantages of the proposed scheme in terms of complexity, outage probability, and effective spectrum efficiency.
Factors Influencing Speech-Language Pathologists’ Application of Terminology for Describing Pediatric Language Assessments

This study investigated speech-language pathologists’ (SLPs) perceptions of factors that influence application of a new taxonomy with terminology for describing child language assessment and identified strategies that may facilitate use of taxonomy terminology to collect data on SLP assessment practice. Semi-structured interviews were conducted with 13 SLPs and data were analyzed using thematic analysis. Three main themes were identified in relation to factors that may influence application including applying the taxonomy is arduous, contextual factors may influence application, and SLP experience and knowledge may influence application. Participants identified a number of strategies to facilitate use of taxonomy by SLPs. Findings from this study give insight into the factors that influence SLPs’ application of a taxonomy of assessment terms. These findings are important for all SLPs in the child language field to consider if the profession is to be effective in establishing greater consistency in use of professional terminology.
Simulation Study and Experimental Position Control of Pneumatic Cylinder Using Sliding Mode Control with on/off Control Valves

Simulation and experimental studies of pneumatic cylinder position control are introduced. High speed on-off solenoid air valve is used instead of the proportional control valve. Sliding mode control with error modification, SMCE, is proposed to drive the air valves with pulse width modulation (PWM) technique. Comparison of the performance of the closed loop position control using SMCE with the traditional PID is held. The simulation model is used to optimize the SMC and PID controller parameters to start the experimental test as a first trial. The experimental results for square and sinusoidal position reference show superiority of the SMCE over the PID in terms of lower steady state errors, faster settling time, and less overshoot. The root mean square error for a sinusoidal input of 0.1 Hz, is 0.22 mm for SMCE and 0.69 mm for PID controller. The maximum absolute errors are 0.66 mm and 1.46 mm for SMCE and PID respectively.
PERFORMANCE OF SOY PROTEIN ADHESIVE ENHANCED BY ESTERIFICATION

Soy protein has shown great adhesion performance to cellulosics and other materials for the manufacture of particleboard, plywood, and various composites. The weakness of a protein-based adhesive is its relatively poor water resistance for outdoor uses. Various chemical and enzymatic methods have been employed to improve the adhesive performance of soy protein. This research studied the effects of esterification on adhesive strength, thermal properties, solubility, and conformational change of soy protein. Free-carboxyl groups of soy protein were esterified with ethanol and different concentrations of hydrochloric acid as catalysts. Esterification rendered protein molecules more hydrophobic by adding the ester groups. With moderate esterification, soy protein showed the maximum increase in adhesiveness and water resistance. The optimum esterification conditions were 10 h with no catalyst. At the optimum condition, esterification increased tensile strength by 20.6%, 61.6%, and 48.1% for dry, wet, and soak strengths, respectively. Hydrochloric acid induced protein denaturation and unfolding by hydrolyzation, and resulted in more ester groups attached on the unfolded structure of protein. The hydrolysis and excess attachment of hydrophobic groups might be detrimental to adhesive performance, especially to water resistance.
