Mobile integrated smart irrigation management and monitoring system using IOT

Agriculture has been the most important practice from very beginning of the human civilization. Traditional methods that are used for irrigation, such as overhead sprinkler and flood type, is not that much efficient. They results in a lot of wastage of water and can also promote disease such as fungus formation due to over moisture in the soil. Automated irrigation system is essential for conservation of the water and indirectly viability of the farm since it is an important commodity. About 85% of total available water resources across the world are solely used for the irrigation purpose. In upcoming years this demand is likely to increase because of increasing population. To meet this demand we must adopt new techniques which will conserve need of water for irrigation process. In automation system water availability to crop is monitored through sensors and as per need watering is done through the controlled irrigation. The almost infinite capabilities of storage and processing, the rapid elasticity makes cloud computing an attractive solution to the large amount of data generated. The idea is to focus on parameters such as temperature and soil moisture. This is a Mobile Integrated and smart irrigation system using IOT based on application controlled monitoring system. The main objective of this project is to control the water supply and monitor the plants through a Smartphone.
Generalization of Thai tone contour in HMM-based speech synthesis

This paper presents an improvement of vowel tone modeling from using an idea of generalization of tone contour by sharing F0 probability stream in the conventional HMM-Based Speech Synthesis system. As of the characteristic of parameter-based speech synthesis, the excitation source (F0) is highly significant to the correctness of synthetic speech especially for a tonal language like Thai. This paper is proposing a method of sharing F0 probability distributions within the same syllabic tones by tying them together before adjusting their probabilities. The implementation and evaluation was done on HTS platform which is based-on HTK. The results show that the proposed method can increase Thai tone correctness at about 14.1% objectively and 90% subjectively.
Word cloud segmentation for simplified exploration of trending topics on Twitter

Twitter is a popular microblogging platform, with 310 million monthly active users as of the first quarter of 2016. It is a rapidly growing microblogging platform where people share opinions, news on any topic of their interest. More than 7000 tweets are posted every second. Due to the enormous volume of data being generated, it becomes difficult to extract useful/meaningful information. Tweets collected from Twitter on a certain topic may consist of numerous conversation threads about relevant sub-topics. However, it is difficult to discern these sub-topics if the data is visualised as a single word cloud. The authors transform a corpus of tweets to a spectral domain and evaluate the results from a number of clustering algorithms, including K-means, latent semantic indexing and non-negative matrix factorisation to construct clustered word clouds that helps identify sub-topics under a broader topic.
The surface layer during artificial carious lesion formation.

This paper gives a detailed description of the development of the surface layer during demineralization of human enamel. Optical inspection of microradiograms of lesions in different stages of development can give the impression that the surface layer increases in thickness with time. Using a more objective method of inspection together with an explicit description, the development of the surface layer was followed with time more quantitatively. This method was based on the changes occurring at the inside of the surface layer. It appeared that the surface layer thickness was constant with time in all lesions investigated. These observations indicate that at constant composition of the buffer solutions, no dissolved material from the body of the lesion is deposited at the inside of the surface layer.
Emotion Regulation Strategies, Secondary Traumatic Stress, and Compassion Satisfaction in Healthcare Providers

ABSTRACT The aim of the present study is to examine the relationships between two emotion regulation strategies (cognitive reappraisal and expressive suppression), secondary traumatic stress, and compassion satisfaction in a sample of 190 healthcare providers. Another aim of this study is to examine if the relations between emotion regulation strategies and traumatic stress symptoms are moderated by compassion satisfaction. The respondents volunteered to take part in the research and completed self-reporting measures describing the use of emotional regulation strategies, the symptoms of secondary traumatic stress, and the compassion satisfaction. The results revealed negative associations between cognitive reappraisal and secondary traumatic stress, while expressive suppression is positively associated with arousal. Moreover, cognitive reappraisal is positively related to compassion satisfaction, while secondary traumatic stress symptoms are negatively correlated with compassion satisfaction. Furthermore, the relationship between expressive suppression and intrusions is moderated by compassion satisfaction. The implications of these results for enhancing professional quality of life in the context of secondary exposure to traumatic life events are discussed.
Chlorhexidine-induced anaphylaxis occurring in the workplace in a health-care worker: case report and review of the literature

Background: Chlorhexidine has been widely used in the occupational field as an effective antiseptic and disinfectant, especially in the health-care services. Several cases of allergic reactions to chlorhexidine have been reported, both in the general population and in workers. Objectives: To describe a case of occupational chlorhexidine-induced severe anaphylaxis that occurred in the workplace in a health-care worker (HCW) and to update the literature on chlorhexidine as a possible occupational allergen. Methods: We report a case of a severe anaphylactic reaction that occurred in the workplace in a 63-year-old man, who had worked as a dentist for over 20 years. We also carried out a systematic review of the literature according to the PRISMA guidelines. No time or language filters were applied. Only occupational case-reports and case-series were included. Results: The causative role of chlorhexidine was suspected owing to the presence of chlorhexidine-containing products in the workplace. Positive results on the Basophil Activation Test confirmed the diagnosis of immediate chlorhexidine-induced hypersensitivity reaction and excluded a role of other disinfectants. No other causes of anaphylaxis were suspected. Our systematic literature review identified 14 cases of occupational chlorhexidine-induced allergy among HCWs; in these cases, the clinical presentation was mild and the symptoms resolved. No cases of systemic reactions in the workplace were reported. Conclusions: This is the first report of chlorhexidine-induced severe anaphylaxis occurring in the workplace. This case report underlines the importance of investigating and being aware of individual and environmental risk factors in the occupational field, which can cause, albeit infrequently, severe reactions with serious consequences.

An account of evolutionary specialization: the AbcR small RNAs in the Rhizobiales

The AbcR small RNAs (sRNAs) are a fascinating example of two highly conserved sRNAs that differ tremendously at the functional level among organisms. From their transcriptional activation to their regulatory capabilities, the AbcR sRNAs exhibit varying characteristics in three well‐studied bacteria belonging to the Rhizobiales order: the plant symbiont Sinorhizobium meliloti, the plant pathogen Agrobacterium tumefaciens, and the animal pathogen Brucella abortus. This review outlines the similarities and differences of the AbcR sRNAs between each of these organisms, and discusses reasons as to why this group of sRNAs has diverged in their genetic organization and regulatory functions across species. In the end, this review will shed light on how regulatory systems, although seemingly conserved among bacteria, can vary based on the environmental niche and lifestyle of an organism.
Distracting Tracking: Interactions Between Negative Emotion and Attentional Load in Multiple-Object Tracking

Stimuli that attract exogenous attention have been shown to interfere with behavioral performance on various tasks. In the present study, participants performed multiple-object tracking (MOT) in conditions where either neutral or negatively valenced images were flashed at fixation. Results reveal a significant impairment of tracking accuracy in the emotional MOT conditions compared to the neutral conditions specifically at the highest level of task difficulty. These findings suggest that emotional distraction is most detrimental when maximal endogenous attentional engagement is required. This interaction between emotional distraction and attentional load is inconsistent with existing models of emotional distraction.
Congruent population structure across paralogous and nonparalogous loci in Salish Sea chum salmon (Oncorhynchus keta)

Whole‐genome duplications are major evolutionary events with a lasting impact on genome structure. Duplication events complicate genetic analyses as paralogous sequences are difficult to distinguish; consequently, paralogs are often excluded from studies. The effects of an ancient whole‐genome duplication (approximately 88 MYA) are still evident in salmonids through the persistence of numerous paralogous gene sequences and partial tetrasomic inheritance. We use restriction site‐associated DNA sequencing on 10 collections of chum salmon from the Salish Sea in the USA and Canada to investigate genetic diversity and population structure in both tetrasomic and rediploidized regions of the genome. We use a pedigree and high‐density linkage map to identify paralogous loci and to investigate genetic variation across the genome. By applying multivariate statistical methods, we show that it is possible to characterize paralogous loci and that they display similar patterns of population structure as the diploidized portion of the genome. We find genetic associations with the adaptively important trait of run‐timing in both sets of loci. By including paralogous loci in genome scans, we can observe evolutionary signals in genomic regions that have routinely been excluded from population genetic studies in other polyploid‐derived species.
Embedded performance validity indicator for children: California Verbal Learning Test – Children’s Edition, forced choice

ABSTRACT Performance validity testing in children undergoing neuropsychological testing is a growing research area. Accurate identification of performance validity is necessary to avoid invalid assessment conclusions. In the present research, a forced choice (FC) trial was created for the California Verbal Learning Test – Children’s Edition (CVLT-C), modeled after the established California Verbal Learning Test – Second Edition (CVLT-II) FC trial. Distractor words were taken directly from the CVLT-II FC Standard Form, with about half being concrete (n = 8) and half abstract (n = 7). The order of the items was organized similarly to the CVLT-II FC to ensure that items from within the same category were not sequential. The Test of Memory Malingering was administered for comparison, and three embedded measures that have previously been validated in adults were also calculated. The CVLT-C FC trial was administered to 40 children, aged 6–16 (M = 12.08, SD = 3.13). Average full scale IQ was 97.3 (SD = 12.41, range = 71–123). Ninety-three percent of examinees performed perfectly on the CVLT-C FC, suggesting high specificity, which is similar to findings for the CVLT-II FC normative group (90%). Results from other embedded measures are also presented.
Absence of the Drosophila jump muscle actin Act79B is compensated by up‐regulation of Act88F

Background: Actins are structural components of the cytoskeleton and muscle, and numerous actin isoforms are found in most organisms. However, many actin isoforms are expressed in distinct patterns allowing each actin to have a specialized function. Numerous studies have demonstrated that actin isoforms both can and cannot compensate for each other under specific circumstances. This allows for an ambiguity of whether isoforms are functionally distinct. Results: In this study, we analyzed mutants of Drosophila Act79B, the predominant actin expressed in the adult jump muscle. Functional and structural analysis of the Act79B mutants found the flies to have normal jumping ability and sarcomere structure. Analysis of actin gene expression determined that expression of Act88F, an actin gene normally expressed in the flight muscles, was significantly up‐regulated in the jump muscles of mutants. This indicated that loss of Act79B caused expansion of Act88F expression. When we created double mutants of Act79B and Act88F, this abolished the jump ability of the flies and resulted in severe defects in myofibril formation. Conclusions: These results indicate that Act88F can functionally substitute for Act79B in the jump muscle, and that the functional compensation in actin expression in the jump muscles only occurs through Act88F.

The curvilinear relationship of early-life adversity and successful aging: the mediating role of mental health

ABSTRACT Objectives: The steeling effect suggests that early-life adversity can have a beneficial impact later in life. However, little is known about its underlying mechanisms and long-term outcomes . The study aimed to examine the role of early-life adversity (ELA) on successful aging, and whether this relationship can be explained by mental and physical health. Method: Socio-demographics, early-life adversity (ELA), individual quality of life (iQoL), and mental and physical health of 270 individuals (Mage = 66.82 years, 71.5% female) were assessed. Polynomial regressions and mediation analyses were conducted. Results: Significant inverse U-shaped associations were found between ELA and iQoL (β = −.59, p = .005) and between ELA and mental health (β = −.64, p = .002), but not between ELA and physical health. Furthermore, mental health significantly mediated the relationship between ELA and iQoL (b = −.84, BCa CI [−1.66, −.27]). Conclusion: Highest level of individual quality of life (i.e. successful aging) was related to a moderate amount of ELA. Additionally, mental health significantly mediated this relationship. These findings suggest that some amount of ELA could be beneficial for successful aging. Resource-focused interventions are needed to improve health and promote successful aging for an underdetected, at-risk subgroup with low early-life adversity.
Differential Engagement of Fermentative Taxa in Gut Contents of the Earthworm Lumbricus terrestris

ABSTRACT The earthworm gut is an anoxic, saccharide-rich microzone in aerated soils. The apparent degradation of diverse saccharides in the alimentary canal of the model earthworm Lumbricus terrestris is concomitant with the production of diverse organic acids, indicating that fermentation is an ongoing process in the earthworm gut. However, little is known about how different gut-associated saccharides are fermented. The hypothesis of this investigation was that different gut-associated saccharides differentially stimulate fermentative microorganisms in gut contents of L. terrestris. This hypothesis was addressed by (i) assessing the fermentation profiles of anoxic gut content microcosms that were supplemented with gut-associated saccharides and (ii) the concomitant phylogenic analysis of 16S rRNA sequences. Galactose, glucose, maltose, mannose, arabinose, fucose, rhamnose, and xylose stimulated the production of fermentation products, including H2, CO2, acetate, lactate, propionate, formate, succinate, and ethanol. Fermentation profiles were dependent on the supplemental saccharide (e.g., glucose yielded large amounts of H2 and ethanol, whereas fucose did not, and maltose yielded large amounts of lactate, whereas mannose did not). Approximately 1,750,000 16S rRNA sequences were affiliated with 37 families, and phylogenic analyses indicated that a respective saccharide stimulated a subset of the diverse phylotypes. An Aeromonas-related phylotype displayed a high relative abundance in all treatments, whereas key Enterobacteriaceae-affiliated phylotypes were stimulated by some but not all saccharides. Collectively, these results reinforce the likelihood that (i) different saccharides stimulate different fermentations in gut contents of the earthworm and (ii) facultative aerobes related to Aeromonadaceae and Enterobacteriaceae can be important drivers of these fermentations. IMPORTANCE The feeding habits of earthworms influence the turnover of elements in the terrestrial biosphere. The alimentary tract of the earthworm constitutes an anoxic saccharide-rich microzone in aerated soils that offers ingested microbes a unique opportunity for anaerobic growth. The fermentative activity of microbes in the alimentary tract are responsible for the in situ production of (i) organic compounds that can be assimilated by the earthworm and (ii) H2 that is subject to in vivo emission by the earthworm and can be trophically linked to secondary microbial events in soils. To gain insight on how fermentative members of the gut microbiome might respond to the saccharide-rich alimentary canal, this study examines the impact of diverse gut-associated saccharides on the differential activation of fermentative microbes in gut contents of the model earthworm L. terrestris.
Control of Oligodendrocyte Precursor Proliferation Mediated by Density-Dependent Cell Cycle Protein Expression

The proliferation of oligodendrocyte precursors is closely regulated in the developing vertebrate CNS. In previous studies we have demonstrated a cell-type-specific density-dependent feedback mechanism that contributes to the control of oligodendrocyte progenitor cell clonal expansion in vitro. Here we demonstrate a density-dependent reduction in the proliferation of oligodendrocyte precursors. This inhibition of proliferation is correlated with increases in expression levels of the cell cycle inhibitor p27Kip1, reductions in the expression of cyclin A and changes in the relative phosphorylation levels of Rb. These changes are reversible on replating at low density suggesting that additional signals are required for terminal oligodendrocyte differentiation.
A hierarchical-learning-based crowdedness estimation mechanism for crowdsensing buses

This paper investigates how to estimate the crowdedness level for crowdsensing buses. Passengers' moving trajectories at the bus stops are able to reflect the crowdedness situation of the bus. And the high accuracy of the existing posture recognition methods for crowdsensing applications can ensure the reliability of the passenger motion monitoring. Based on these observations, we propose a hierarchical-learning-based crowdedness estimation mechanism, namely HCE, to obtain the crowdedness level of a crowdsensing bus. The motion sequence and gait information of a participatory passenger is obtained via the sensing data from sensors in smartphones and can be expressed by eigenvectors. Then the feature vectors are classified as different individual crowdedness levels based on hierarchical support vector machine (SVM) classifier and hidden markov model (HMM). Finally the crowdedness levels of the buses can be reckoned by the estimated crowdedness levels from all the individual passengers. The experimental results show that our mechanism can achieve at least 83% accuracy.
Meaning of Illness and Self-Care in Patients With Type 2 Diabetes

Purpose The purpose of this study was to assess the relationship between meaning of illness, diabetes knowledge, self-care understanding, and behaviors in a group of individuals with type 2 diabetes. Methods Patients diagnosed with type 2 diabetes completed questionnaires with measures for diabetes knowledge, self-care understanding, diet adherence, and control problems based on the validated Diabetes Care Profile, as well as a 5-factor Meaning of Illness Questionnaire (MIQ) measure. Linear regression investigated the associations between self-care outcomes and the 5 MIQ factors. Results After adjustment for possible confounders, both diabetes self-care understanding and diet adherence were negatively and significantly associated with little effect of illness. Control problems were negatively associated with degree of stress/change in commitments. Diabetes knowledge was not significantly associated with meaning of illness. Conclusion Aspects of the meaning attributed to illness were significantly associated with self-care in patients with type 2 diabetes. Therefore, cognitive appraisals may explain variances observed in self-care understanding and behaviors. Based on these results, it is important to understand the negative effect that diabetes could have when promoting self-care understanding and diet adherence. In addition, it shows that helping patients address the stress and changing commitments that result from diabetes may help decrease the amount of diabetes control problems, even if there is little effect on diabetes understanding. Taking these differences into account may help in creating more personalized and effective self-care education plans.
