REA-6TiSCH: Reliable Emergency-Aware Communication Scheme for 6TiSCH Networks

From the perspective of the emerging Industrial Internet of Things (IIoT), the 6TiSCH working group has been created with the main goal to integrate the capabilities of the IEEE 802.15. 4e time-slotted channel hopping (TSCH) with the IPv6 protocol stack. In order to support time-critical applications in IIoT, reliable real-time communication is a key requirement. Specifically, aperiodic critical traffic, such as emergency alarms, must be reliably delivered to the destination-oriented directed acyclic graph root within strict deadline bounds to avoid system failure or safety-critical situations. Currently, there is no mechanism defined in the 6TiSCH architecture for timely and reliably handling of such traffic and its prioritization over the noncritical one. In this article, we introduce REA-6TiSCH, a reliable emergency-aware communication scheme to support real-time communications of emergency alarms in 6TiSCH networks. In REA-6TiSCH, the aperiodic emergency traffic is opportunistically enabled to hijack transmission cells preassigned for the regular periodic traffic in the TSCH schedule. Moreover, we introduce a distributed optimization scheme to improve the probability that an emergency flow is delivered successfully within its deadline bound. To the best of our knowledge, this is the first approach to incorporate emergency alarms in 6TiSCH networks. We evaluate the performance of REA-6TiSCH through extensive simulations and the results show the effectiveness of our proposed method in handling emergency traffic compared to the Orchestra scheme. Additionally, we discuss the applicability of REA-6TiSCH and provide guidelines for real implementation in 6TiSCH networks.
A report on 14 unrecorded bacterial species isolated from the Nakdong River, South Korea

The microbial community in a river water ecosystem is different from that in any other ecosystems, such as soil and marine. These freshwater bacteria are the key players of global environmental processes and carbon cycling (Falkowski et al., 2008; Williamson et al., 2018). The bacterial community in freshwater is predominantly composed of Proteobacteria, Actinobacteria, Cyanobac­ teria, Cytophaga­Flavobacterium­Bacteroidetes, and Verrucomicrobia (Newton et al., 2011). Advances in indepth sequencing technology have quickly improved our knowledge of bacterial diversity and the key processes of microbial ecology, which led to the understanding of the relationship between the functioning of aquatic ecosystems and the formation of bacterial communities on ecology (Edwards et al., 2006; Huse et al., 2008). However, the cultivation of a predominant group of microorganisms is essential for understanding the bacteria and their ecological roles in freshwater environments. Our research site, the Nakdong River is the longest river in South Korea, and its total watershed is 23,384 square kilometers wide. The Nakdong River and its tributaries also serve as a major source of drinking water for the inhabitants of the river basin and nearby locations. However, environmental changes have occurred, as untreated nitrogen and phosphorus nutrients flow into the river. The acceleration of eutrophication caused by the inflow of contaminated waters has led to an increase in phytoplankton abundance and changed bacterial species composition in rivers (Sin et al., 2005; Chun et al., 2019). Thus, there has been a significant increase in academic interest in the relationship between river ecosystems and microorganisms that act as decomposers (Miettinen et al., 1997; Zhou et al., 2016). As a part of the research program conducted and supJournal of Species Research 9(2):77-84, 2020
Implementation of low-rise construction projects as factor of improving level and quality of life in depressed territories

The conducted research was devoted to the development and validation of criteria for low-rise housing construction in small towns and rural areas remote from major cities. The purpose of the research is to develop fundamental criteria that allow achieving a synergistic effect based on integrated development of a territory, together with improvement of standard of living and creation of comfortable conditions for the population. This research can be applied in design of programs for development of construction industry, including low-rise construction. Scientific merit of the article lies in the fact that the developed criteria make it possible to identify the main features of efficient low-rise housing construction: comfort, safety, energy efficiency, modernity of engineering equipment. These features are able to ensure construction of such energy-efficient low-rise comfortable and affordable housing, which will contribute to sustainable development of a region and make small towns and villages attractive for young professionals and young families.
Enhancement of eurycomanone biosynthesis in cell culture of longjack (Eurycoma longifolia) by elicitor treatment

In this study, the effect of elicitors such as yeast extract (YE), methyl jasmonate (MeJA) and salicylic acid (SA) on the accumulation of eurycomanone in Eurycoma longifolia cell cultures were investigated. Suspension cells of E. longifolia was cultured in Murashige and Skoog (MS) medium supplemented with 30 g/L sucrose, 1.25 mg/L naphthaleneacetic acid (NAA) and 1 mg/L kinetin at a shaking speed of 120 rpm. Elicitors were added in the culture at different concentrations and times to stimulate eurycomanone accumulation in the Eurycoma longifolia cells. Eurycomanone content was determined by HPLC with a C18 column, flow rate of 0.8 mL/min, run time of 17.5 min, and a detector wavelength of 254 nm. The stationary phase was silica gel and the mobile phase was acetonitrile: H2O. Non-elicited cells were used as the control. The study showed the effect of different elicitor concentrations, YE at 200 mg/L, MeJA at 20 μM and SA at 20 μM stimulated high production of eurycomanone. In which, treatment of 20 μM MeJA after 4 days of culture resulted in the highest accumulation of this compound (17.36 mg/g dry weight), approximately 10-fold higher than that of untreated cells (1.70 mg/g dry weight).
Incidence of Atrial Fibrillation and Socio-demographic and Clinical Characterization and Life Habits of Cardiac Surgery Patients

Objective: Of investigating the incidence of atrial fibrillation and sociodemographic and clinical data and life habits of patients in the postoperative period at a University Hospital (UH) in Maranhao, Brazil. Method: Retrospective cross-sectional research, sample composed of 29 medical records of adult patients undergoing valve replacement and/or myocardial revascularization who developed atrial fibrillation between the years 2016 to 2017. The project was approved by the Research Ethics Committee of the UH, no 2,855,350. Results: Atrial fibrillation had an incidence of 13.3%. There was a prevalence of patients aged 70 to 89 years (34.5%), with a mean age 62.1 years, of male sex (72.4%), brown race (79.3%), from the countryside (96.6%), in stable union (58, 6%), with low education (27.6%), rural workers (51.7%), of Catholic religion (76.0%), and with an income of 1 to 2 minimum wages (62.1%). Systemic arterial hypertension (69%) stood out among the preexisting diseases, and mitral stenosis/insufficiency (41.3%) and coronary artery disease (34.5%) among the cardiac diseases. The study found overweight (48.3%), former smokers (31%), former alcoholics (13.8%), and values of 3 or 4 in the stroke risk score (31%). The tests performed were electrocardiogram, echocardiogram, coronary angiography and Holter. Conclusion: The identification of the incidence of atrial fibrillation and the sociodemographic and clinical characterization may contribute to better understand the development of this arrh- -ythmia, providing opportunities for reflective care practice in health promotion, prevention and control of morbidity and mortality.
Morphology supports ­the setaphyte hypothesis: mosses plus liverworts form a natural group

The origin and early diversification of land plants is one of the major unresolved problems in evolutionary biology. Occurring nearly half a billion years ago, the transmigration of green organisms to land changed the landscape and provided the food source for terrestrial life to invade a vast uninhabited space, adapt and radiate. Although bryophytes (mosses, liverworts and hornworts) are often regarded as the earliest terrestrial organisms, the order of their divergence remains contentious even as molecular analyses become more conclusive with expanded taxon sampling, massive genetic data and more sophisticated methods of analysis (Cox et al. 2018; Morris et al. 2018). Indeed, virtually every combination of relationships among bryophytes has been proposed based on molecules (Qiu et al. 2006; Wickett et al. 2014; Cox et al. 2018). Fortunately, in 2018 it appears that we are approaching a consensus based on molecules, and that is that although bryophytes may or may not be monophyletic, mosses plus liverworts form a natural group (Puttick et al. 2018). In this essay, we point out that this inference is neither new nor surprising as it has been the fundamental conclusion of morphological analyses for over 25 years starting with an exhaustive cladistic analysis of characters associated with motile cell development in green plants (Garbary et al. 1993).
Explaining Popular Support for Wind Energy in the United States

In the last 35 years, wind energy in the United States has transformed from being radical and experimental to becoming a mainstream, feasible, and efficient source of electricity. In this article, we compare wind energy acceptance to acceptance of other energy sources, in particular solar, coal, natural gas, and oil. Through an online survey of 1317 adults throughout the United States, we also examine the impact of individuallevel characteristics such as gender, race, age, socio-political factors, and value orientation on a person’s support for renewable energy policy. We find that support for wind energy is higher than for fossil fuels for all groups regardless of demographics, educational attainment, or political ideology. However, support for wind energy policies is highest among millennials, non-whites, college educated, liberals, and those with high egoistic and biospheric values.
kmr: A command to correct survey weights for unit nonresponse using groups’ response rates

In this article, we describe kmr, a command to estimate a microcompliance function using groups’ nonresponse rates (Korinek, Mistiaen, and Ravallion, 2007, Journal of Econometrics 136: 213–235), which can be used to correct survey weights for unit nonresponse. We illustrate the use of kmr with an empirical example using the current population survey and state-level nonresponse rates.
Teacher Philosophies of Career Development Events: Implications for Curriculum in Agriculture, Food, and Natural Resources Education

Student engagement in Career and Technical Student Organizations (CTSOs) offer tremendous opportunities for content learning, leadership development, and career preparation. Included in the scope of CTSOs are skills contests, competitions designed to test student knowledge and skills within respective content areas. Within school-based agricultural education, these skills contests are called career development events (CDEs). Building upon existing research identifying the importance of CDE preparation to student performance and knowledge transfer, the current study quantified CDE preparation occurring within agricultural education classrooms, educator philosophies of CDEs, and the relationship between philosophies and CDE preparation. Findings indicate the majority of responding teachers held a student development philosophy and incorporated moderate to high amounts of CDE preparation within their classroom curriculum. Additionally, findings suggest a practically significant relationship between teacher philosophies and CDE preparation, with teachers possessing a competition and achievement philosophy facilitating the highest amount of CDE preparation during classroom instruction. In total, findings provide important insights into CDE preparation within agricultural education as well as a template for evaluating similar relationships throughout other CTE areas.
Escherichia coli in Chicken Carcasses in Southern Brazil: Absence of Shigatoxigenic (STEC) and Isolation of Atypical Enteropathogenic (aEPEC)

23/July/2019 Approved: 23/November/2019 ABSTRACT The aim of this study was to investigate the presence of shiga toxin-producing Escherichia coli (STEC) and atypical enteropathogenic Escherichia coli (aEPEC) in frozen chicken carcasses sold at stores in southern Brazil. Typical E. coli colonies were enumerated in 246 chicken carcasses, and the presence of stx1 , stx2 , eae genes was investigated in their rinse liquid and in E. coli strains isolated from those carcasses. Strains of E. coli were also investigated for the presence of bfp gene. A median of 0.6 cfu.g -1 (ranging from <0.1 to 242.7 cfu.g -1 ) of typical E. coli colonies was found in the carcasses. Shiga toxin-encoding genes ( stx1 and stx2 ) were not detected, indicating that the chicken carcasses were negative for STEC. The intimin protein gene ( eae ) was detected in E.coli isolated from 4.88% of the carcasses; all tested strains were negative for the bfp gene and were classified as aEPEC. Twenty-two aEPEC strains were tested for resistance to ten antimicrobials and subjected to macrorestriction (PFGE). All the tested aEPEC strains were fully susceptible to cephalosporins, ciprofloxacin and colistin. Resistance to sulfonamide (65%), ampicillin (55%), tetracycline (50%) and gentamicin (45%) were the most frequent. The PFGE profile demonstrated a low level of similarity among the resistant strains, indicating that they were epidemiologically unrelated. The results indicate that aEPEC strains can contaminate chicken meat, and their association with strains implicated in human diarrhea needs to
Assessment of factors influencing the adoption of improved crop management practices (ICMP) by smallholder farmers in the Boane district, Mozambique

This paper seeks to assess the factors influencing the adoption of the improved crop management practices (ICMP) in Boane District in Mozambique. The study was carried out using a qualitative survey method with a semi-structured interview schedule. Regression analysis and Pearson correlations were used to analyse the factors, constraints, and opportunities influencing the adoption of the improved crop management practices. The study covered a sample of 50 households. The results of the study show that the majority of the farmers (68%) in the Boane District adopted the improved crop management practices, compared to those who did not adopt them (32%). According to the logistic regression analysis, two factors (age and access to credit) were significant (p<0.05) at the 5% level of significance with the adoption of ICMP, meaning that age and access to credit have an influence on the adoption of the improved crop management practices in the Boane District. The study recommended that the Agricultural Development Fund and the district development should solve the challenge of low financial investments, which is the major problem of most smallholder farmers, limiting their response to the production process, and to adopting the improved crop management practices in the Boane District.

A New Framework for Understanding Memories and Preference for Music

What can musical memories tell us about preference, and what can musical preferences tell us about memory? In this article we contrast the two perspectives using a dialogic conversation, drawing on insights brought into relief at the recent Music and Lifetime Memories conference. We use dialogue to present two different bodies of relevant background literature and theory and consider their overlaps, interactions, and contradictions in depth. We then compare our two different approaches to the same dataset – the Desert Island Discs archive – which provide complementary perspectives and insights. We interpret each other’s analyses from our own perspectives, and finally conclude with reflections on future directions for the field.
Milk and cheese microbiome for safety and quality of dairy products

The aim of this project is to develop and increase knowledge of key factors influencing the presence of clostridial spores in milk and factors affecting, directly or indirectly, technological characteristics and fermentation of milk, make it more or less susceptible to the development of defects (swelling). Aim of the project is to characterize by 1D/2D-gel electrophoresis and next-generation sequencing coupled to shotgun mass spectrometry the global microbiota isolated from ‘Grana Padano’ cheese. In particular the target is to identify the sub-proteome of Clostridium tyrobutyricum present in cheese and to investigate differences in proteins involved in the metabolic pathway of butyric acid in different stages of ripening and milk treatment (e.g. lysozyme treatment).
Semantic Segmentation on 3D Occupancy Grids for Automotive Radar

Radar sensors have great advantages over other sensors in estimating the motion states of moving objects, because they detect velocity components within one measurement cycle. Moreover, numerous successes have already been achieved regarding the classification of such objects. However, the advantage of instantaneous velocity measurement is lost when detecting static objects, so that their classification is much more demanding. In this paper, we use semantic segmentation networks to distinguish between frequently occurring infrastructure objects. The resulting semantic grids provide a location-based classification of the vehicle environment. Since even modern radars have a significantly poorer angular resolution than lidars, the relatively thin radar point cloud is accumulated in advance and transformed into 2D or 3D grids that act as network inputs. Occupancy grids are particularly advantageous here, since they calculate not only the obstacles but also the free spaces. With suitable parameter selection, which is very challenging due to the complexity of radar measurement, the resulting grids allow for good association with camera images. Finally, in order to evaluate possible advantages of 3D grids as network input with respect to the segmentation result, we created and evaluated a simulation dataset and two different real-world datasets in car parks and on motorways. As a result, Jaccard coefficients between 81% and 88% were achieved, depending on the dataset. It was also found that 3D input images lead to improvements in the car park dataset.
Simulated Assessment of Summer Maize Drought Loss Sensitivity in Huaibei Plain, China

In an agricultural drought risk system, crop drought loss sensitivity evaluation is a fundamental link for quantitative agricultural drought loss risk assessment. Summer maize growth processes under various drought patterns were simulated using the Cropping System Model (CSM)-CERES-maize, which was calibrated and validated based on pit experiments conducted in the Huaibei Plain during 2016 and 2017 seasons. Then S-shaped maize drought loss sensitivity curve was built for fitting the relationship between drought hazard index intensity at a given stage and the corresponding dry matter accumulation and grain yield loss rate, respectively. Drought stress reduced summer maize evapotranspiration, dry matter, and yield accumulation, and the reductions increased with the drought intensity at each stage. Moreover, the losses caused by drought at different stages were significantly different. When maize plants were exposed to a severe water deficit at the jointing stage, the dry matter and grain yield formation were greatly affected. Therefore, maize growth was more sensitive to drought stress at the jointing stage when the stress was serious. Furthermore, when plants encountered a relatively slight drought during the seedling or jointing stage, which represented as a lower soil water deficit intensity, the grain yield loss rates approached the maximum for the sensitivity curves of these two stages. Therefore, summer maize tolerance to water deficit at the seedling and jointing stages were weak, and yield formation was more sensitive to water deficit during these two stages when the deficit was relatively slight.
Effect of β-Glucan Stabilized Virgin Coconut Oil Nanoemulsion on Properties of Croaker Surimi Gel

ABSTRACT Effects of virgin coconut oil (VCO) nanoemulsion stabilized by β-glucan and β-glucan solution at final β-glucan levels of 5–20% (based on solid weight of surimi) on croaker surimi gel were comparatively studied. Increases in breaking force, deformation, and fracture constant were found in surimi gel containing VCO nanoemulsion stabilized by 5% β-glucan, whereas a decrease in all properties was observed as the level of β-glucan in nanoemulsion increased. The addition of β-glucan solutions led to continuous decrease in breaking force, deformation, and fracture constant, compared to the control. Addition of both β-glucan stabilized nanoemulsion and β-glucan solutions resulted in decrease in viscoelastic moduli. Power law model represented viscoelastic behavior of all the gels. Expressible moisture content decreased, while whiteness increased with the addition of β-glucan-stabilized nanoemulsion, compared with gel containing VCO. However, both expressible moisture content and whiteness increased with the addition of β-glucan solutions, at all levels used. Addition of β-glucan-stabilized nanoemulsion resulted in finer gels compared to the control gel added with only VCO. Generally, overall likeness score increased for gel containing VCO nanoemulsion stabilized by 5% β-glucan. The surimi gel containing both medium chain fatty acids and β-glucan, functional ingredients, could be developed as a new product.
