Power-over-Tether UAS Leveraged for Nearly-Indefinite Meteorological Data Acquisition

Use of unmanned aerial systems (UASs) in agriculture has risen in the past decade. These systems are key to modernizing agriculture. UASs collect and elucidate data previously difficult to obtain and used to help increase agricultural efficiency and production. Typical commercial off-the-shelf (COTS) UASs are limited by small payloads and short flight times. Such limits inhibit their ability to provide abundant data at multiple spatiotemporal scales. In this paper, we describe the design and construction of the tethered aircraft unmanned system (TAUS), which is a novel power-over-tether UAS leveraging the physical presence of the tether to launch multiple sensors along the tether at multiple altitudes. With power from a ground station, the TAUS can acquire continuous data for several hours . The system is used to sense atmospheric conditions and temperature gradients across altitude. The development of the prototyped system is presented, along with the results of field experiments. The influence that power losses across the tether have on the sensors’ abilities to accurately sense is discussed. We demonstrate a 6-hour continuous flight at an altitude of 50 feet, and a 1-hour flight at sunset to acquire the gradually decreasing atmospheric temperature from an array of 6 sensors. An empirical evaluation of the system’s performance found that the prototype successively demonstrated proof of concept by considerably increasing flight times and throughput by simultaneously acquiring data from the sensor array. The TAUS will be improved by integrating performance-monitoring circuitry, elevated levels of algorithm-based autonomy, and multivariable sensors.
Roughing the caster! Sexism and perceived female sports broadcasters’ credibility

ABSTRACT Women football broadcasters still face challenges in obtaining careers and advancing professionally. The researchers sought to bridge the gap in research to better understand the audience’s perceptions of female sports broadcasters in sports, specifically the National Football League. Using an experimental design the researchers explored individual perceptions of the credibility of a female play-by-play commentator in comparison to a male play-by-play commentator. The results demonstrate that participants believed female sports broadcasters were not as credible or exciting as male sports broadcasters. The researchers consider and discuss the implications of these findings and suggest future research in the area.
Phase Retrieval With Learning Unfolded Expectation Consistent Signal Recovery Algorithm

Phase retrieval algorithms are now an important component of many modern computational imaging systems. A recently proposed scheme called generalized expectation consistent signal recovery (GEC-SR) shows better accuracy, speed, and robustness than numerous existing methods. Decentralized GEC-SR (deGEC-SR) addresses the scalability issue in high-resolution images. However, the convergence speed and stability of these algorithms heavily rely on the settings of several handcrafted tuning factors with inefficient turning process. In this work, we propose deGEC-SR-Net by unfolding the iterative deGEC-SR algorithm into a learning network architecture with trainable parameters. The parameters of deGEC-SR-Net are determined by data-driven training. Numerical results show that deGEC-SR-Net provides substantially faster convergence than deGEC-SR and exhibits superior robustness to noise and prior mis-specifications.
Loggerhead turtle (Caretta caretta) by catches on long‐lines: The importance of olfactory stimuli

Abstract In order to reduce sea turtle by‐catches on surface drifting long‐lines during professional swordfish (Xiphias gladius) fishing, the relevance of olfactory stimuli in eliciting predation by loggerhead sea turtles (Caretta caretta) was investigated. Choice experiments were run in captivity. Squid‐shaped plastic lures having or lacking scomber odour were presented to 27 specimens (22 immatures and 5 adults). The turtles’ behavioural responses highlighted the importance of chemical clues in eliciting approaching and biting behaviours. This study was carried out within the framework of the EU‐Life Project ‘Urgent conservation measures for C. caretta in the Pelagie islands’ (LIFE 99 NAT/IT/006271).
Diel variation of nutrient retention is associated with metabolism for ammonium but not phosphorus in a lowland stream

In-stream nutrient retention is an important ecosystem function because it can regulate nutrient fate and export to downstream ecosystems. Temporal variation in nutrient retention in streams has been studied extensively at the annual and seasonal scale but less thoroughly at the diel scale. However, understanding temporal variability in nutrient uptake at the diel scale can increase understanding of the role of photoautotrophic primary production on nutrient uptake in streams, especially open-canopy streams. We hypothesized that nutrient retention mostly depends on autotrophic demand in open-canopy streams and that it varies following the diel pattern of gross primary production (GPP). We therefore evaluated the temporal variation in phosphate (PO43−) and ammonium (NH4+) uptake at a daily scale in a highly-productive Pampean stream that is dominated by a dense assemblage of macrophytes and filamentous algae. We conducted 6 slug additions of PO43− and NH4+ over a 24-h period and quantified reach-scale nutrient uptake concurrently with measurements of whole-stream metabolism and chemical variables during additions (including nitrates and nitrites). The study stream had extremely high uptake of PO43− and NH4+ (>90 and >75% retention of the P and N mass added, respectively). Uptake of PO43− did not vary throughout the day. Estimated PO43− uptake from GPP accounted for only a small fraction of observed PO43− uptake. Thus, another mechanism, such as heterotrophic demand by microbial assemblages or adsorption onto sediments, could also have contributed to PO43− uptake in the study stream. In contrast, NH4+ uptake clearly varied throughout the day. Up to 48% of the observed NH4+ uptake rate could be explained by NH4+ estimated from GPP, and NH4+ demand was positively associated with GPP, indicating a high dependence on photoautotrophic demand. An increase of nitrite (NO2−) concentration during additions (representing up to 70% of the added mass of NH4+) suggests that nitrification contributed to the diel pattern of NH4+ uptake. Our results indicate that nutrient uptake does not always rely on autotrophic demand in open-canopy streams and that other abiotic and dissimilatory mechanisms may explain the diel patterns of nutrient retention. In addition, our study highlights the need to measure uptake metrics throughout the day to obtain an accurate estimate of nutrient retention on a daily scale.
Gross anatomy of the musculature and a new description of the reproductive system of Tanaisia bragai and Tanaisia inopina (Trematoda: Eucotylidae) analysed by confocal laser scanning microscopy

Confocal scanning laser microscopy has become an important tool to clarify the organization of the musculature and innervation, as well as the morphology of the reproductive and alimentary tract of various helminth species. The goal of this work was to describe the morphology of the reproductive system and the gross anatomy of the musculature of adults of the species Tanaisia bragai and Tanaisia inopina by means of confocal scanning laser microscopy. The helminths were found parasitizing the kidney collection ducts of Columba livia, in the municipality of Juiz de Fora, Brazil. These helminths were stained with Mayer’s carmalum, mounted on permanent slides and observed through a confocal scanning laser microscope. The tomographic images showed the morphology of the organs and glands of the reproductive system, along with the general morphology of the musculature of the body wall, oral sucker, acetabulum, pharynx, intestinal caeca, oesophagus and reproductive system ducts. The present work is the first re-characterization of the reproductive tract of T. bragai and T. inopina. We also present the first description of the general morphology of the gametes and cells of the glands associated with the reproductive apparatus of these species.
Exploring digital marketing resources, capabilities and market performance of small to medium agro-processors. A conceptual model

Agro-processors are important to economies of developing countries as they help create jobs, alleviate poverty and improve food security. These goals are important for Zimbabwe – a country ranked among the poorest countries in the world. However, small to medium sized agro-processors face marketing challenges, especially in the digital environment. The challenges are mainly due to limited digital marketing resources and capabilities as witnessed by poor website design, and low visibility in trending social media platforms. As such, marketing costs remain high, yet digital marketing provides an opportunity to cut costs, increase visibility, improve customer relationships, offer enhanced market sensing, and increase customer convenience. In view of these possible contributions, this paper sought to establish whether possession of certain digital marketing resources and capabilities can improve agro-processors’ market performance. This is important because marketing is contextual, theories and concepts that apply in developed markets are not easily applicable to developing countries. As such, a new set of skills and knowledge is required. This paper contributes to literature on resource-based view, marketing capability, subsistence marketing, and marketing performance. To achieve that, the researchers reviewed and developed a conceptual model using literature on digital marketing, marketing resources, capabilities and market performance. The model and paper at large are original in that it takes a digital marketing and developing country perspective. Extant literature in Zimbabwe lacks an explanation to the impact of digital marketing resources, and capabilities on market performance of agro-processors. The study implies that different markets and contexts require different knowledge and skills; as such, researchers must test existing and new frameworks in different environments to develop relevant knowledge.
Range-Ambiguous Clutter Suppression for the SAR-GMTI System Based on Extended Azimuth Phase Coding

A range-ambiguous clutter suppression approach based on extended azimuth phase coding (EAPC) is proposed to handle the range ambiguity of the multiple-input multiple-output synthetic aperture radar (MIMO-SAR) system for ground moving target indication (GMTI) application. The echoes from different ambiguous range regions can be well separated in the transmit spatial frequency domain by properly designing the EAPC shift factor. In the sequel, a set of transmit filters are employed to extract the echoes of each ambiguous region independently. Then the azimuth deramp operation is applied to the extracted data to focus the target energy of the desired region while the residual target energy of other regions is still smeared due to the mismatched reference function. After this, the adaptive matched filtering algorithm is adopted to suppress the clutter and detect the moving target. Finally, numerical simulation experiments are presented to demonstrate that the developed framework can obtain good results for range-ambiguous clutter suppression and ground moving target detection.
The Deployment of Young Readers´ Visual Attention across Orthographic Strings: The Influence of Stems and Suffixes

ABSTRACT The goal of the paper was to investigate whether morphological units – stems and suffixes – influence orthographic processing by modulating visual attention demands to the task. Orthographic processing was measured with a visual one-back task requiring letters to be detected within pseudowords not including stems/suffixes, or containing real stems or real suffixes. Fourth grade children (between 9.5 and 10.5 years old) who read in a transparent orthography of a morphologically rich and agglutinative language (Basque) were tested. The results showed that the presence of morphemes in the strings did not improve letter detection performance though it slightly modulated the distribution of visual attention, showing a bias toward the processing of central letters in the presence of a stem. We suggest that the presence of highly regular and recurrent structures prioritizes stem identification, which when achieved, reduces visual attention deployment across the remaining letters.
δ-calculus: A New Approach to Quantifying Location Privacy☆

: With the rapid development of mobile wireless Internet and high-precision localization devices, location-based services (LBS) bring more convenience for people over recent years. In LBS, if the original location data are directly provided, serious privacy problems raise. As a response to these problems, a large number of location-privacy protection mechanisms (LPPMs) (including formal LPPMs, FLPPMs, etc.) and their evaluation metrics have been proposed to prevent personal location information from being leakage and quantify privacy leakage. However, existing schemes independently consider FLPPMs and evaluation metrics, without synergizing them into a unifying framework. In this paper, a unified model is proposed to synergize FLPPMs and evaluation metrics. In detail, the probabilistic process calculus (called δ -calculus) is proposed to characterize obfuscation schemes (which is a LPPM) and integrate α -entropy to δ -calculus to evaluate its privacy leakage. Further, we use two calculus moving and probabilistic choice to model nodes’ mobility and compute its probability distribution of nodes’ locations, and a renaming function to model privacy leakage. By formally defining the attacker’s ability and extending relative entropy, an evaluation algorithm is proposed to quantify the leakage of location privacy. Finally, a series of examples are designed to demonstrate the efficiency of our proposed approach.
Using Utterance Recall to Assess Second Language Proficiency

Obtaining quick and reliable evidence regarding the proficiency of learners is a perennial issue in second language (L2) learning research. In this study, we examined naturalistic utterance recall as a measure of L2 learning proficiency that can be easily extracted from videos and automatically scored using the video’s captions. In our recall task, learners listen to audio clips and write down as much of the utterance as they can remember. We evaluated this naturalistic recall task with a sample of English native speakers who are learning Spanish at beginner to advanced levels, as well as Spanish native speakers. The results suggest that our recall measure is a better predictor of a learner’s ability to translate heard sentences than a shortened version of a standardized listening multiple-choice comprehension test. Our findings suggest naturalistic utterance recall can offer an accurate and efficient method for predicting foreign language proficiency.
Physical versus economic water footprints in crop production: a case study for China

Abstract. A core goal of sustainable agricultural water resources management is to implement lower water footprint (WF), i.e., higher water productivity, while maximising economic benefits in crop production. However, previous studies mostly focused on crop water productivity from a single physical perspective. Little attention is paid to synergies and trade-offs between water consumption and economic value creation of crop production. Distinguishing between blue and green water composition, grain and cash crops, and irrigation and rainfed production mode in China, this study calculates the production-based WF (PWF) and derives the economic value-based WF (EWF) of 14 major crops in 31 provinces for each year over 2001–2016. The synergy evaluation index (SI) of PWF and EWF is proposed to evaluate quantitatively the synergies and trade-offs between the two. Results show that both the PWF and EWF of most considered crops in China decreased with the increase of crop yield and prices. The high (low) values of both PWF and EWF of grain crop tended to obvious cluster in space and there existed a huge difference between blue and green water in economic value creation. Moreover, the SI revealed a serious incongruity between PWFs and EWFs both in grain and cash crops. Negative SI values occurred mostly in northwest China for grain crops, and overall more often and with lower values for cash crops. Unreasonable regional planting structure and crop prices resulted in this incongruity, suggesting the need to promote regional coordinated development to adjust the planting structure according to local conditions and to regulate crop prices rationally.
Next Generation Machine Learning for Urban Water Management

Determining the end uses of water in residential properties can facilitate a more proactive approach to water literacy, awareness and demand management. This type of information enables the public, government and water businesses to implement more cost-effective and targeted demand management and customer engagement strategies. This study sought to develop a next-generation water management system that combines advanced digital metering technology with machine learning to provide customers and water utilities with a breakthrough in household-scale water management. This breakthrough system ( Autoflow ) provides a range of functions including autonomous water end-use disaggregation, demand forecasting and customer-specific efficiency recommendations.
Effects of crowding on blood constituents and flesh quality variables in Atlantic salmon (Salmo salar L.)

Se compararon en los dias 0, 1, 4, 7 y 10 post mortem, en terminos de variables de la calidad de la carne y constituyentes sanguineos, los efectos de la anestesia (como tratamiento del control) y el confinamiento controlado con disminucion del nivel de oxigeno en salmones tamano cosecha (Salmo salar). Los peces fueron mantenidos en triplicado en estanques y muestreados despues de anestesiar con AQUI-S® y despues de confinar por un periodo de una hora. Dieciocho peces de cada tratamiento fueron insensibilizados mediante un golpe en la cabeza, se les extrajo sangre mediante la puncion de la vena caudal para luego ser sangrados mediante el corte de branquias y posteriormente procesados para obtener los filetes. Todas las variables sanguineas a excepcion del cortisol fueron significativamente mas altas (P < 0, 05) en los peces confinados comparados con los peces anestesiados. El pH muscular inicial fue mas bajo en los pescados confinados unicamente en los dias 0, 1 y 4 post mortem. El color muscular obtuvo una puntuacion significativamente mas baja (P < 0, 05) en los peces confinados que en aquellos anestesiados en los dias 0 y 1 post mortem. La perdida del peso fue mayor (P < 0, 05) en los peces confinados, aumentando en ambos tratamientos en los siguientes dias post mortem. La concentracion de astaxantina muscular no mostro ninguna diferencia estadistica entre los tratamientos ni en los dias post mortem. Se puede concluir que el confinamiento y el bajo nivel de oxigeno tienen un efecto negativo en las variables sanguineas y en parametros de calidad de carne, disminuyendo la puntuacion de color, bajando el pH muscular inicial y aumentando la perdida del peso de los filetes.
Lipid production by a cellulolytic strain of Aspergillus niger

Studies on lipid formation by a cellulolytic mould. Aspergillus niger AS‐101, were carried out in shake flasks. The maximum amount of lipid accumulated comprised 17% and 14·9% of the mycelial dry weight on glucose and cellulose media, respectively. Unsaturated fatty acids comprised around 80% of the total fatty material, with linoleic acid predominating.
The location of raspberry ringspot and tomato black ring viruses in the nematode vector, Longidorus elongatus (de Man)

SUMMARY Electron microscopy of thin sections of Longidorus elongatus (de Man) fed on plants infected with raspberry ringspot and tomato black ring viruses showed virus-like particles in the lumen of the buccal capsule and in the space between the stylet and the guiding sheath. In sections of L. elongatus fed on plants infected with arabis mosaic virus, which it does not normally transmit, a few virus particles were seen in the buccal capsule but none was associated with the stylet guiding sheath. It is suggested that the association of virus particles with the cuticular guiding sheath is an explanation of the specificity of virus transmission evident in L. elongatus.
Genetic identification of ophichthid fishes through DNA barcoding

Abstract Ophichthidae is the most ecologically diverse family of the order Anguilliformes; however, high morphological similarity and a long larval stage make precise identification difficult. The aim of the present study was to examine the potential for barcoding of ophichthid fishes. A total of 81 mitochondrial cytochrome C oxidase subunit I (COI) barcode sequences were obtained from 23 species and 12 genera of ophichthid fishes collected in the Taiwan Strait. The average Kimura two-parameter distances within species, genera, and families were 0.48%, 18.25%, and 18.79%, respectively; thus, the mean interspecific distance was 31-fold higher than the mean intraspecific distance, which demonstrates good efficiency in DNA barcoding. The sequence divergence among species also varied substantially from 4.60% to 25.90%. This evaluation demonstrates the high efficiency of DNA barcoding for species identification to facilitate research on the diversity and conservation of ophichthid fishes.
Detection on OAR7 of QTL affecting fat and protein yields in dairy sheep.

Abstract The objective of this paper was identifying QTL that affect fat and protein yields in dairy sheep independently of milk yield. Data were collected in an experimental flock of 887 ewes organized in a daughter design. QTL detection focused on OAR7 where 13 microsatellites were available. The genetic abilities to produce fat and protein independently from the ability to produce milk were estimated as the residuals of the regression of EBV for fat and protein yields on EBV for milk yield. One QTL affecting fat yield (CWP=0.00009) and one QTL affecting protein yield (CWP=0.006) were detected. The most probable QTL location was 115.3 cM in the Sheep Best Position Linkage Map Version 4.7 for both traits. No QTL affecting milk yield was detected. The analysis of fat and protein yields independently of milk yield is an effective strategy to identify chromosomal regions affecting milk composition with no detrimental effect on milk yield.
Viscoelastic coagulation test for liver transplantation

Coagulation and transfusion management in patients undergoing liver transplantation is challenging. Proper perioperative monitoring of hemostasis is essential to predict the risk of bleeding during surgery, to detect potential causes of hemorrhage in time, and to guide hemostatic therapy. The value of conventional coagulation test is questionable in the acute perioperative setting due to their long turnaround time and the inability to adequately reflect the complex changes in hemostasis in patients with liver disease. Viscoelastic coagulation tests provide simultaneous measurement of multiple aspects of whole-blood coagulation including plasmatic coagulation and fibrinolytic factors and inhibitors that reflect most aspects of hemostasis. Coagulation initiation, mechanical clot stability, and fibrinolysis can be estimated immediately using point-of-care techniques. Therefore, viscoelastic coagulation tests including ROTEM & TEG would be useful to guide patient blood management strategy during liver transplantation.
