Published: June 2019

Sensible heat exchange has important consequences for urban meteorology and related applications. Directional radiometric surface temperatures of urban canopies observed by remote sensing platforms have the potential to inform estimations of urban sensible heat flux. An imaging radiometer viewing the surface from nadir cannot capture the complete urban surface temperature, which is defined as the mean surface temperature over all urban facets in three dimensions, which includes building wall surface temperatures and requires an estimation of urban sensible heat flux. In this study, a numerical microclimate model, Temperatures of Urban Facets in 3-D (TUF-3D), was used to model sensible heat flux as well as radiometric and complete surface temperatures. Model data were applied to parameterize an effective resistance for the calculation of urban sensible heat flux from the radiometric (nadir view) surface temperature. The results showed that sensible heat flux was overestimated during daytime when the radiometric surface temperature was used without the effective resistance that accounts for the impact of wall surface temperature on heat flux. Parameterization of this additional resistance enabled reasonably accurate estimates of urban sensible heat flux from the radiometric surface temperature.

Published: June 2019

Oceanic eddies play an important role in global energy and material transport, and contribute greatly to nutrient and phytoplankton distribution. Deep learning is employed to identify oceanic eddies from sea surface height anomalies data. In order to adapt to segmentation problems for multi-scale oceanic eddies, the pyramid scene parsing network (PSPNet), which is able to satisfy the fusion of semantics and details, is applied as the core algorithm in the eddy detection methods. The results of eddies identified from this artificial intelligence (AI) method are well compared with those from a traditional vector geometry-based (VG) method. More oceanic eddies are detected by the AI algorithm than the VG method, especially for small-scale eddies. Therefore, the present study demonstrates that the AI algorithm is applicable of oceanic eddy detection. It is one of the first few of efforts to bridge AI techniques and oceanography research.
Smart Cupboard for Assessing Memory in Home Environment

Published: June 2019

Sensor systems for the Internet of Things (IoT) make it possible to continuously monitor people, gathering information without any extra effort from them. Thus, the IoT can be very helpful in the context of early disease detection, which can improve peoples’ quality of life by applying the right treatment and measures at an early stage. This paper presents a new use of IoT sensor systems—we present a novel three-door smart cupboard that can measure the memory of a user, aiming at detecting potential memory losses. The smart cupboard has three sensors connected to a Raspberry Pi, whose aim is to detect which doors are opened. Inside of the Raspberry Pi, a Python script detects the openings of the doors, and classifies the events between attempts of finding something without success and the events of actually finding it, in order to measure the user’s memory concerning the objects’ locations (among the three compartments of the smart cupboard). The smart cupboard was assessed with 23 different users in a controlled environment. This smart cupboard was powered by an external battery. The memory assessments of the smart cupboard were compared with a validated test of memory assessment about face–name associations and a self-reported test about self-perceived memory. We found a significant correlation between the smart cupboard results and both memory measurement methods. Thus, we conclude that the proposed novel smart cupboard successfully measured memory.

Published: June 2019

Knowing the long-dated dynamic changes of vegetation in the Mu Us Desert is critical for strengthening sustainable management of vegetation restoration projects in the next planned cycle until 2050. To predict leaf area indexes (LAIs) under long-dated climate scenarios (2013–2050) in the Mu Us Desert, the relationship between earlier meteorological data and LAI was tracked with regression analysis on the basis of LAI data from the Global Land Surface Satellite (GLASS) and the grid meteorological data during 1982–2012, and the LAIs were estimated based on five-Global Circulation Model (GCM) ensemble means under three representative concentration pathways (RCP 2.6, RCP 4.5 and RCP 8.5). We found an increasing trend in precipitation and a significant increase in potential evapotranspiration (PET) during the earlier period in the Mu Us Desert, and that could continue into the long-dated under three RCPs in the Mu Us Desert. Warming trends occur in the earlier and long-dated periods for annual average air temperature. Compared with the observations, the temperature rises respectively by 0.6 ℃, 0.7 ℃, and 1 ℃ under the three RCPs mentioned above. The annual maximum LAI largely increased with a rate-of-change of 0.029 m2·m−2·yr-1. Precipitation has been a major influencing factor to vegetation dynamics and growth in the Mu Us Desert. The permissible LAIs by 2050 are 0.42–0.88 m2·m−2, 0.42–0.87 m2·m−2, and 0.41–0.87 m2·m−2 under the three RCPs, respectively. Contrasted with the baseline period (1982–2012), the LAI is found to be already close to the current value in the northwestern and southern Mu Us Desert.

Published: June 2019

Coral reefs are harboring a large part of the marine biodiversity and are important ecosystems for the equilibrium of the oceans. As a consequence of anthropogenic CO2 emission, a drop in pH and an increase in seawater temperature is observed in the Gulf coastal waters that potentially threaten coral assemblages. An experimental study was conducted on two species of corals to assess the effect of ocean warming and ocean acidification on the net calcification rate. Two pH conditions 8.2 and 7.5 and three temperatures, 22.5, 27.5 and 32.5 °C, were considered. Net calcification rates were measured using 45Ca radiotracer. Both temperature and pH had a significant effect on net calcification rates following a similar pattern for both species. The highest calcification rate was observed at low temperature and high pH. Increased temperature and decreased pH led to a decrease in net calcification rates. An interactive effect was observed as the effect of pH decreased with increasing temperature. However, the two species of coral were able to calcify in all the tested combination of temperature and pH suggesting that they are adapted to short term changes in temperature and pH. Ability to calcify even at a high temperature of 32.5 °C that is identical to the summertime Gulf seawater temperature under both the ambient and low pH condition with no mortalities, raises a question: are these corals adapted to high seawater temperatures and low pH? More in-depth assessments will be required to confirm if this is an adaptation to higher temperatures in Persian Gulf corals.
A New Approach to Assess the Effect of Various Humic Compounds on the Metabolic Activity of Cells Participating in Methanogenesis
Authors: Stepanov Nikolay , Senko Olga , Perminova Irina , Efremenko Elena
Published: June 2019

The possible use of the concentration of intracellular adenosine triphosphate (ATP) as a parameter enabling quick and adequate evaluation of the metabolic activity of methanogenic cells was demonstrated in the work. This approach was used to analyze the effect of introducing potassium humate and fulvic acids (1–10 g/L) into media with four different methanogenic consortia producing biogas. The ATP concentration was analyzed by the bioluminescent luciferin–luciferase method at the beginning and end of the process. During the entire process, the biogas composition, biogas efficiency, and the kinetics of methanogenesis in the presence of humic compounds were determined. The increase in the concentration of potassium humate led to a decrease in the overall energy status of the cells and reduced methanogenesis efficiency. However, fulvic acids introduced into the media stimulated methanogenesis in half of the tested consortia, which was accompanied by an increase in ATP concentration in cell samples. So, a positive correlation between the metabolic activity of cells in biogas formation and the concentration of ATP was observed. ATP concentration control appears to be an attractive tool for finding compounds that suppress methanogenesis in landfills.

Published: June 2019

In the current study, laminar heat transfer and direct fluid jet injection of oil/MWCNT nanofluid were numerically investigated with a finite volume method. Both slip and no-slip boundary conditions on solid walls were used. The objective of this study was to increase the cooling performance of heated walls inside a rectangular microchannel. Reynolds numbers ranged from 10 to 50; slip coefficients were 0.0, 0.04, and 0.08; and nanoparticle volume fractions were 0–4%. The results showed that using techniques for improving heat transfer, such as fluid jet injection with low temperature and adding nanoparticles to the base fluid, allowed for good results to be obtained. By increasing jet injection, areas with eliminated boundary layers along the fluid direction spread in the domain. Dispersing solid nanoparticles in the base fluid with higher volume fractions resulted in better temperature distribution and Nusselt number. By increasing the nanoparticle volume fraction, the temperature of the heated surface penetrated to the flow centerline and the fluid temperature increased. Jet injection with higher velocity, due to its higher fluid momentum, resulted in higher Nusselt number and affected lateral areas. Fluid velocity was higher in jet areas, which diminished the effect of the boundary layer.
Correcting Bias in Crowdsourced Data to Map Bicycle Ridership of All Bicyclists

Published: June 2019

Traditional methods of counting bicyclists are resource-intensive and generate data with sparse spatial and temporal detail. Previous research suggests big data from crowdsourced fitness apps offer a new source of bicycling data with high spatial and temporal resolution. However, crowdsourced bicycling data are biased as they oversample recreational riders. Our goals are to quantify geographical variables, which can help in correcting bias in crowdsourced, data and to develop a generalized method to correct bias in big crowdsourced data on bicycle ridership in different settings in order to generate maps for cities representative of all bicyclists at a street-level spatial resolution. We used street-level ridership data for 2016 from a crowdsourced fitness app (Strava), geographical covariate data, and official counts from 44 locations across Maricopa County, Arizona, USA (training data); and 60 locations from the city of Tempe, within Maricopa (test data). First, we quantified the relationship between Strava and official ridership data volumes. Second, we used a multi-step approach with variable selection using LASSO followed by Poisson regression to integrate geographical covariates, Strava, and training data to correct bias. Finally, we predicted bias-corrected average annual daily bicyclist counts for Tempe and evaluated the model’s accuracy using the test data. We found a correlation between the annual ridership data from Strava and official counts (R2 = 0.76) in Maricopa County for 2016. The significant variables for correcting bias were: The proportion of white population, median household income, traffic speed, distance to residential areas, and distance to green spaces. The model could correct bias in crowdsourced data from Strava in Tempe with 86% of road segments being predicted within a margin of ±100 average annual bicyclists. Our results indicate that it is possible to map ridership for cities at the street-level by correcting bias in crowdsourced bicycle ridership data, with access to adequate data from official count programs and geographical covariates at a comparable spatial and temporal resolution.
Type of RNA Packed in VLPs Impacts IgG Class Switching—Implications for an Influenza Vaccine Design
Authors: C. Gomes Ariane , Roesti E. S. , El-Turabi Aadil , Bachmann Martin F.
Published: June 2019

Nucleic acid packed within virus-like particles (VLPs) is shown to shape the immune response and to induce stronger B cell responses in different immunisation models. Here, using a VLP displaying the highly conserved extracellular domain of the M2 protein (M2e) from the influenza viruses as an antigen, we demonstrate that the type of RNA packaged into VLPs can alter the quality of the induced humoral response. By comparing prokaryotic RNA (pRNA), eukaryotic RNA (eRNA) and transfer RNA (tRNA), we find that pRNA induces the most protective IgG subclasses using a murine influenza model. We provide evidence that this process is predominantly dependent on endosomal Toll-like receptor (TLR7), and rule out a role for cytoplasmic mitochondrial antiviral signalling protein (MAVS) and its upstream retinoic acid-inducible gene-I-like receptors (RIG-I). Our findings provide considerations for the rational design of VLP-based vaccines and the immunomodulation exerted by TLR7 ligands packaged within the particles. Based on this work, we conclude that VLPs packing prokaryotic RNA must be preferred whenever a response dominated by IgG2 is desired, while eukaryotic RNA should be employed in order to induce a response dominated by IgG1.
Effects of Nonnative Fishes on Commercial Seine Fisheries: Evidence from a Long-Term Data Set
Authors: Orfinger Alexander B. , Lai Quan T. , Chabot Ryan M.
Published: June 2019

Dozens of introduced exotic freshwater fish species inhabit the state of Florida. These nonnative fishes interact with freshwater commercial fisheries in a variety of ways, influencing catch abundance, composition, and revenue. Using a 22-year data set collected from a commercial haul seine fishery, we aimed to explore the dynamics of yield and revenue in relation to nonnative fishes, with emphasis on the suckermouth armored catfishes (Pterygoplichthys spp.). Using profit index metrics and the inverse Simpson’s diversity index, we found that non-native tilapia (Oreochromis spp.) and brown hoplo (Hoplosternum littorale) provided economic benefits while suckermouth armored catfishes seemed to disrupt catch consistency and lower profit index values. To reduce the negative impacts of the suckermouth armored catfishes and subsequently exert pressure on their population, we suggest marketing these edible fishes for human and/or animal consumption.

Authors: Richard Gudaj  , István Komlósi  , Endre Brydl
Published: June 2019

In the last 20-30 years, lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimizing lameness. Those areas are related to poor facilities, lack of straw, problems with labor and basic management.

Published: June 2019

The plantation of willow varieties was established in 2009. The 40 different varieties and clones of Salix were planted at a research field in Kolíňany (Nitra district). The paper evaluates results from the first growing season in 2009. The survival rate of planted cuttings ranged from 55.56 % to 100.00 % after the first year. The lowest survival rate was reached by Terra Nova variety. The stem numbers per plant ranged from 1.17 ±0.37 to 2.53 ±0.98. The average height of one-year old stem varied from 65.82 ±36.60 cm to 225.58 ±68.61 cm. The average stem diameter ranged from 6.90 ±2.63 mm to 14.34 ±3.39 mm. There were statistically very significant differences in parameters of stem height stem diameter and stem numbers per plant among studied varieties/clones. The statistic method used was analysis of variance ANOVA. The varieties were then divided into 6 groups according to their similarity in observed parameters after the first growing season by cluster analysis. The best results were reached by varieties/clones classified in the second group. The survival rate, stem diameter and stem height values of these varieties/clones were above average.

The effect of the “Transcarpathia” Free Economic Belt on the investment activities of the region and its development of foreign trade relations
Authors: Katalin Koval
Published: June 2019

The article analyses the figures of foreign investments and their territorial distribution and their change due to the impact of the “Transcarpathia” Free Economic Belt. The article studies the consequences of the liquidation of the “Transcarpathia” Free Economic Belt and the issue of restoring allowances that formerly existed on its territory.The Free Economic Belt that was founded in 1998 and its customs and tax allowances invoked the settlement of affiliated firms of several world corporations, like the “Eurocar”, the “Yadzaki”, or the “Jabil”. However in 2005 the government of that time repealed all allowances granted by the “Transcarpathia” Free Economic Belt, and due to this the increasing dynamics of the amount of foreign stocks which was penetrating into the economy of Transcarpathia started to decrease. Many companies halted their work which went alongside with closing-down several thousands of workplaces. The working “Transcarpathia” Free Economic Belt had a positive effect on the social and economic indices of the region, so discussions regarding its restoration have already been started between the president of Ukraine and the governor of the region.

Published: June 2019

There are various methods available for measurement of lipid oxidation in foods.Changes in chemical, physical, or organoleptic properties of fats and oils during oxidation may be monitored to assess the extent of lipid oxidation. However, there is no uniform and standard method for detecting all oxidative changes in all food systems. The available methods to monitor lipid oxidation in foods and biological systems may be divided into two groups. The first group measures primary oxidative changes and the second determines secondary changes that occur in each system.

Published: June 2019

This article makes a review of scientific literature with the objective of knowing the different perspectives and interpretations on rural - urban migration of young people and adolescents at risk of social exclusion. The methodology applied in the framework of the qualitative approach allowed the organization, study and interpretation of 25 research published in the digital library of the Autonomous University of Barcelona. As a result, it was understood that migration is a complex, dynamic and multifaceted phenomenon. In this perspective emerges the type of rural-urban migration movement that falls on the group of young people and adolescents who "go out in search of work" and those who "migrate to study". This population of migrant youth and adolescents from the countryside to the city is one of the most vulnerable segments. In this condition, young subjects are exposed to multiple dynamic processes of social, educational, labor, political and cultural exclusion.

The research focused on assessing the level of scientific evidence that exists about the use of cognitive strategies as a determinant in the reading comprehension activity in students of different educational levels: primary, secondary and higher. A systematic review of scientific articles and theses was carried out, without restriction of dates or types of study. We reviewed the full articles that included on the importance of cognitive strategies and reading comprehension. Ten articles were selected, most of these looking for the relationship exists. Good percentage of the authors of the articles and thesis reviewed conclude that the good use of cognitive strategies develops reading comprehension skills reaching the desired goal, the understanding of the text. It even depends on these strategies that the student develops increasingly complex performance criteria for reading comprehension.
El sistema educativo peruano y la pérdida de identidad cultural andina en la región Puno
Authors: Vargas Diana , Pérez Katia
Published: June 2019

Peru is characterized by the plurality of languages and in the Puno region by the Quechua, Aymara and Castilian languages, as the official language of Peru, on the other hand, the use of native languages is restricted in the educational institutions of urban and rural areas. in the university for the hegemony of Castilian. This research aims to investigate the Peruvian educational system as an influence on the loss of the Quechua - Aymara cultural identity of the Puno region, the research is of a descriptive type that corresponds to the quantitative approach. The research aims to rescue and value cultural identity in education in order to preserve the Andean culture in the Puno region and therefore in Peru and strengthen their training to face the sudden changes in educational models in Peru, since the language is the symbol of cultural identity, understanding that the language fulfills a functional role in society and to transmit its traditions, narrations and its sense of Andean man, as collective social promotion of culture, symbol of reciprocity and cooperation or solidarity. The languages are valid (77.8%) and strengthened in the Andean societies that are considered an instrument for social interaction.
Acoustic Cues Used by Learners of English
Authors: Reid Danica
Published: June 2019

Second language learners must acquire the ability to use word boundary cues to segment continuous speech into meaningful words. Previous studies have used two types of s+stop clusters to test second language English speakers on their ability to segment fluent English speech: cross-boundary clusters (this table) where allophonic aspiration is present and word-initial clusters (this stable) where allophonic aspiration is absent. These studies suggested that first language segmentation strategies influence second language segmentation. The goal of this study was to test real-time processing of these cluster types by second language learners from one language where cue adaptation was possible (Mandarin Chinese) and one where a new cue would have to be learned (French). Results did not support the idea that first language segmentation strategies influence second language segmentation, but found that both language groups had high accuracy of identification despite showing uncertainty in real-time processing.
Reconciling CV phonotactics and high vowel deletion in Japanese
Authors: Whang James
Published: June 2019

High vowel devoicing is a productive process in Japanese, where /i, u/ become unphonated between voiceless obstruents. Recent studies have shown that the vowels can completely delete as a result of the process, resulting in surface consonant clusters. This seemingly conflicts with the strong CV phonotactic preference that has repeatedly been shown in both phonological and psycholinguistic studies of Japanese. This paper proposes that the apparent conflict can be resolved by having phonotactic repairs and high vowel devoicing apply at different phonological levels, adopting a more sophisticated phonological representation than simple /underlying/ vs. [surface] forms. The proposed framework also makes an empirically testable prediction regarding syllabification of clusters that result from high vowel deletion.
Native and Non-Native Patterns in Conflict: Lexicon vs. Grammar in Loanword Adaptation in Brazilian Portuguese
Authors: Guzzo Natália Brambatti
Published: June 2019

English loanwords with /ʌ/ that are part of the Brazilian Portuguese (BP) lexicon are normally produced with [ɐ] (pub: [ˈpɐbɪ]). Although [ɐ] is the closest segment to /ʌ/ in the native inventory, it is highly constrained in BP: it is an allophone of /a/ that can only appear in nasal contexts. This paper investigates whether native speakers of BP generalize to novel loanwords the adaptation pattern of English /ʌ/ that is present in the BP lexicon. Two experiments were conducted, one with real loanwords and one with nonce loanwords. In the Real Loanword Experiment, participants consistently used [ɐ] both in oral (pub) and nasal contexts (funk), as predicted given the patterns in the lexicon. In the Nonce Loanword Experiment, participants used [ɐ] significantly more frequently in nasal contexts – in oral contexts, the most frequent adaptation was [a]. This reveals that speakers employ their native grammar to filter new loanwords: in contexts where [ɐ] is not licensed, they favor the corresponding licensed form. These results suggest that native speakers do not generalize non-native patterns that are present in the lexicon, mirroring what has been observed for the generalization of unnatural patterns in native grammars (e.g., Garcia 2017; Jarosz 2017).

Kashaya Foot Extrametricality as Post-Accentuation
Authors: Buckley Eugene
Published: June 2019

Kashaya, an endangered Pomoan language of northern California, has an iambic stress pattern, assigned within words and phrases. Accent regularly shifts rightward from a (CV:) foot onto the following foot, including opaque contexts when length is lost or moved by other processes. This paper brings into the analysis a class of lexical triggers of accent shift: specific stems with no long vowels on the surface that nonetheless also trigger this shift. I propose an analysis of all varieties of accent shift as alignment of constituents, requiring the head foot to follow the triggering foot. Particular evidence for alignment comes from the fact that it is blocked by phrasal resyllabification of a word-final consonant. I argue for a unified analysis of all cases that employs a diacritic at the level of the foot, which also provides an account for opacity.
DAMAGE DETECTION FOR UHPFRC COMMUNICATION TOWER BASED ON FREQUENCY DATA AND PARTICLE SWARM OPTIMIZATION
Authors: Jabbar Sarah , Hejazi Farzad , Hanoon Ammar N. , Rashid Rizal S. M.
Published: June 2019

Advances in the telecommunication and broadcasting sectors have increased the need for networking equipment of communication towers. Slender structures, such as towers, are sensitive to dynamic loads, such as vibration forces. Therefore, the stability and reliability performance of towers can be maintained effectively through the prompt detection, localization, and quantification of structural damages by obtaining the dynamic frequency response of towers. However, frequency analysis for damaged structures requires long computational procedures and is difficult to perform because of the damages in real structures, particularly in towers. Therefore, this study proposed a correlation factor that can identify the relationship between frequenciesunderhealthy and damaged conditions of ultra high performance fiber-reinforced concrete (UHPFRC) communication towers using particle swarm optimization. The finite element method was implemented to simulate three UHPFRC communication towers, and an experimental test was conducted to validate and verify the developed correlation factor
Inner Source Pickup Ions from Chondritic Smooth Interplanetary Dust Particles
Authors: Quinn P. R. , Schwadron N. A. , Möbius E.
Published: June 2019

Inner source pickup ions (PUIs) are thought to be produced by the interaction between solar wind ions and interplanetary dust particles (IDPs). The amount of PUIs produced and their velocity distribution depend on the composition, density, porosity, and size of the IDPs. Quinn et al. simulated the production of PUIs from chondritic porous (CP) IDPs. The study showed that the composition of PUIs produced from CP IDPs nearly resembled the solar wind. The purpose of this study is to expand upon Quinn et al. to chondritic smooth (CS) IDPs to get a more complete description of inner source PUI production. We simulate the production and transport of C+ and O+ PUIs using the Stopping and Range of Ions in Matter and the Energetic Particle Radiation Environment Module. We consider five production mechanisms: solar wind recycling, neutralization, backscattering, sputtering, and sputtering-induced recycling. Comparisons are made to observational studies that used the Charge-Time-Of-Flight instrument on board the SOlar and Heliospheric Observatory. Results indicate that sputtering is the dominant mechanism. This results in an inner source PUI composition that resembles the dust grains, which are rich in species such as C and O and poor in species such as Ne. However, studies by Ulysses show that inner source PUIs produced inside of ∼0.5 au have a composition similar to that of the solar wind. Thus, we conclude that the IDP population close to the Sun is dominated by CP IDPs rather than CS IDPs.
