Fast converging elitist genetic algorithm for knot adjustment in B-spline curve approximation
Authors: Bureick Johannes , Alkhatib Hamza , Neumann Ingo 
Published: August 2019

AbstractB-spline curve approximation is a crucial task in many applications and disciplines. The most challenging part of B-spline curve approximation is the determination of a suitable knot vector. The finding of a solution for this multimodal and multivariate continuous nonlinear optimization problem, known as knot adjustment problem, gets even more complicated when data gaps occur. We present a new approach in this paper called an elitist genetic algorithm, which solves the knot adjustment problem in a faster and more precise manner than existing approaches. We demonstrate the performance of our elitist genetic algorithm by applying it to two challenging test functions and a real data set. We demonstrate that our algorithm is more efficient and robust against data gaps than existing approaches.

Abstract

Background
Irritable bowel syndrome (IBS) is one of the most common digestive diseases. The aim of this clinical trial was to determine the effectiveness of Achillea wilhelmsii C. Koch on the symptom severity and quality of life (QOL) in patients with IBS.

Methods
The patients were randomized into two groups of 45 each. The QOL and symptom severity of the patients were evaluated at baseline and at completion of the treatments by means of IBS-QOL and IBS severity index.

Results
The mean severity of clinical symptoms in the Achillea wilhelmsii C. Koch receiving groups before and after the treatment was 282.56 ± 103.57 and 178.06 ± 88.40, and in the placebo group was 265.93 ± 93.56 and 197.74 ± 106.26, respectively. The mean QOL in the Achillea wilhelmsii C. Koch receiving group before and after treatment was 51.49 ± 11.98 and 50.44 ± 13.39 and in the placebo group was 60.71 ± 11.97 and 58.39 ± 11.67, respectively. In both groups, there was a significant difference in the recovery rate in each group (p<0.05). However, the mean difference between the two groups before and after intervention was not significantly different (p>0.05). Also, no patient reported any adverse events during the trial. Although the symptom severity and QOL in both groups were improved compared to those before intervention, there was no significant difference between the two groups.

Conclusion
It is recommended to conduct future studies with larger sample size and longer treatment periods, and also investigate the efficacy on the IBS subtypes, separately.

Authors: Buscemi Andrea , Pennisi Vincenzo , Rapisarda Alessandro , Pennisi Alfio , Coco Marinella 
Published: August 2019

Abstract

Background
This randomized controlled pilot study evaluated the efficacy of osteopathic treatment in patients with moderate-to-severe chronic obstructive pulmonary disease (COPD) assessed using spirometry, COPD Assessment Test (CAT) and six minutes walking test (6MWT). The main goals were to improve the quality of life of patients with stable moderate-to-severe COPD, and to revise the parameters of the assessment tests, such as spirometry and 6MWT.

Methods
The study comprised several phases and patients were divided into two groups: group A (controls) received conventional pharmacological treatment with Indacaterol–Glycopyrronium and, while group B (OMT group) received both traditional therapy and osteopathic manipulative treatment (OMT) at different stages of the study. The osteopathic approach focused on maxillary sinus, vertebral-pleural ligaments, phrenic nerves, ribs, pleura, lungs, bronchi, subclavian muscles, and trapezoid and conoid ligaments.

Results
Overall, 32 patients were randomized and treated. Patients of the OMT group got better improvements in all tests compared to the control group: spirometry: FVC (p<0.5411), total FEV1 (p<0.5061); CAT: OMT (p<0.0005) - controls (p<0.188) 6MWT OMT (p<0.0038) - controls (p<0.5326). The clinical results collected in phase (T3) confirm those obtained in the first sessions; the results of CAT questionnaire (p<0.0005) and 6MWT (p<O, OO38) highlighted score improvements of patients treated with osteopathy compared to patients in the other group.

Conclusions
The results showed that the patients with COPD who received the conventional pharmacological treatment in association with the OMT therapy demonstrated a good response to the osteopathic treatment, thus leading to significant improvements in their health and wellbeing, and a better daily functioning.

Non-cooperative game theory based stepwise power tariff model using Monte-Carle simulation for agricultural consumers
Authors: Talwariya Akash , Singh Pushpendra , Kolhe Mohan 
Published: August 2019

Abstract
In the present study the concept of non-cooperative game theory is proposed in the retail electricity market for introducing stepwise power tariff model (SPT) for agricultural consumers. The objective of the paper is to increase the energy generation through green energy generation sources (GEGS), introduction of plug-in hybrid electric vehicles, education of families, standard wiring and appliance efficiency in tariffs for agricultural consumers with non-cooperative game theory. Agricultural consumers are able to generate a huge amount of electricity through GEGS and are able to control the consumption in their own way, and the non-cooperative game theory is introduced. Energy consumption pattern varies with respect to time during off-peak load period to peak load period; during the peak load period the demand is high as compared to off peak load hour duration energy consumption for the consumers and policy makers interrupting the energy supply during peak hours for agricultural consumers. To maintain the balance between generation and consumption, energy saving is essentially required and needs to maintain the consumption patterns and increase the penetration level of distributed generation at the agricultural consumer end due to availability of land. This paper proposes an algorithm for a demand response methodology using SPT with non-cooperative game theory model based on monthly energy consumption to maintain the balance. The uncertainty about energy generation through GEGS taken in consideration using Monte-Carlo simulation (MCS). Simulation results obtained by the proposed methodology are compared with the conventional methodology of energy tariff used in India and provide better results for active consumers and generate a considerable amount of electricity through GEGS.

Abstract
The aim of the current article is to analyze the construction process of participative agroecological knowledge in the mountainous region of Rio de Janeiro State, Brazil. The challenges resulting from the climate-related natural disaster-extreme event with heavy rains - that has affected the region in January 2011 were herein highlighted. Local data, a literature review and semi-structured interviews, conducted with participants from the study area, as well as a focus group involving key people, were used to observe social behaviors. Strategies aimed at expanding the adoption of agroecological practices, mainly the practices concerning the use of cover crops, were proposed. The need to adapt to farmers’ time and aspirations, inherent in the technological stage of each farmer, such as the economic gains resulting from the agroecological transition, was shown in the current study.
Determinant Factors of Farmers’ Willingness to Start Agritourism in Rural Nepal

Published: August 2019

Abstract
Agritourism in developing countries is regarded as a tool not only for rural development but also for poverty alleviation. However, up until now, the majority of the studies on agritourism have been conducted in economically strong countries, focusing on already-developed agritourism destinations. Thus, the main objectives of this study were to investigate farmers’ willingness before the establishment of agritourism and the factors that are driving their motivation. The results of an empirical questionnaire survey in rural Nepal conducted in August 2017 revealed that farmers are willing to engage in agritourism. Furthermore, the results indicate that agritourism has a statistical connection with elements related to tourism and an element related to agriculture. Specifically, willingness to start agritourism is connected with the types of tourist attracted and the farmers’ willingness to share land resources. Each factor is further explained by employing three different variables. In summary, those farmers who are 21 to 40 years old, have returned from foreign countries, are frequently involved in community activities, and are relatively educated are the potential agritourism practitioners in rural Nepal. This study suggests that policymakers should pay special consideration to farmers with the above traits for agritourism development.

Abstract
This investigation was inspired by an increasing global issue on how to improve soil quality while using alternative preparations instead of synthetic fertilizers. The main aim of a three-year study was to investigate the influence of horn-manure preparation on enzyme activity and nutrient content in soil and pumpkin yield. The results showed that significantly higher amounts of P (respectively 106 and 79 mg kg−1 CAL), K (149 and 106 mg kg−1 CAL), nitrogen (5.41 and 3.21 mg kg−1), ammoniacal nitrogen (9.38 and 3.45 mg kg−1) and mineral nitrogen (7.97 and 5.67 mg kg−1) were measured in the plots where the horn-manure preparation was used. A higher activity of the soil enzymes (urease activity was 1.93 times higher and the saccharase activity was 1.05 times higher) were identified with horn-manure. The average soil CO2 flux (Fc) value, when using horn-manure preparation (from 56 till 70 day), was significantly higher by 5.32% in the middle of the growing season. The yield of pumpkin was significantly increased by 18% with horn manure treatments. Significant positive correlations were identified between pumpkin yield and urease activity, and saccharase activity, as well as soil P and K.

Published: August 2019

AbstractThis article introduces the issue of recognition and normalisation of temporal expressions for the Polish language. We describe what temporal information is and we present TimeML specification, adapted to Polish as a model for the description of temporal expressions. Classes of temporal expressions are presented as well as guidelines for annotation, normalisation of these expressions and our approach to corpus annotation and temporal expressions recognition. The key aspect of the work is the description of the features used for the recognition, the use of the method for selection and creation of feature templates for the model of Conditional Random Fields. We demonstrate the experiments and conclusions drawn from them.
A Weakly supervised word sense disambiguation for Polish using rich lexical resources
Authors: Janz Arkadiusz , Piasecki Maciej 
Published: August 2019

Abstract
Automatic word sense disambiguation (WSD) has proven to be an important technique in many natural language processing tasks. For many years the problem of sense disambiguation has been approached with a wide range of methods, however, it is still a challenging problem, especially in the unsupervised setting. One of the well-known and successful approaches to WSD are knowledge-based methods leveraging lexical knowledge resources such as wordnets. As the knowledge-based approaches mostly do not use any labelled training data their performance strongly relies on the structure and the quality of used knowledge sources. However, a pure knowledge-base such as a wordnet cannot reflect all the semantic knowledge necessary to correctly disambiguate word senses in text. In this paper we explore various expansions to plWordNet as knowledge-bases for WSD. Semantic links extracted from a large valency lexicon (Walenty), glosses and usage examples, Wikipedia articles and SUMO ontology are combined with plWordNet and tested in a PageRank-based WSD algorithm. In addition, we analyse also the influence of lexical semantics vector models extracted with the help of the distributional semantics methods. Several new Polish test data sets for WSD are also introduced. All the resources, methods and tools are available on open licences.

Their crystal structures can be considered as organo-inorganic hybrids constructed of alternating [(UO2)2(TO4)3(H2O)n]2−slabs (T = Se6+, S6+,n = 1, 2) and layers containing templating organic moieties and/or hydronium ions and water molecules. The organic and inorganic parts of the structures are linked by multiple hydrogen bonds. Besides structure description, we offer topological analysis of the inorganic fragments with UO2:TO4ratio of 2:3 as modular units resulting from self-assembly of fundamental chains formed by [(UO2)2(TO4)2] tetramers andTO4tetrahedra.
Blue Light Increases Neuronal Activity-Regulated Gene Expression in the Absence of Optogenetic Proteins
Authors: Tyssowski Kelsey M. , Gray Jesse M. 
Published: August 2019

AbstractOptogenetics is widely used to control diverse cellular functions with light, requiring experimenters to expose cells to bright light. Because extended exposure to visible light can be toxic to cells, it is important to characterize the effects of light stimulation on cellular function in the absence of optogenetic proteins. Here we exposed mouse cortical cultures with no exogenous optogenetic proteins to several hours of flashing blue, red, or green light. We found that exposing these cultures to as short as 1 h of blue light, but not red or green light, results in an increase in the expression of neuronal activity-regulated genes. Our findings suggest that blue light stimulation is ill suited to long-term optogenetic experiments, especially those that measure transcription, and they emphasize the importance of performing light-only control experiments in samples without optogenetic proteins.
Large-Scale Networks for Auditory Sensory Gating in the Awake Mouse

Published: August 2019

AbstractThe amplitude of the brain response to a repeated auditory stimulus is diminished as compared to the response to the first tone (T1) for interstimulus intervals (ISI) lasting up to hundreds of milliseconds. This adaptation process, called auditory sensory gating (ASG), is altered in various psychiatric diseases including schizophrenia and is classically studied by focusing on early evoked cortical responses to the second tone (T2) using 500-ms ISI. However, mechanisms underlying ASG are still not well-understood. We investigated ASG in awake mice from the brainstem to cortex at variable ISIs (125–2000 ms) using high-density EEG and intracerebral recordings. While ASG decreases at longer ISIs, it is still present at durations (500–2000 ms) far beyond the time during which brain responses to T1 could still be detected. T1 induces a sequence of specific stable scalp EEG topographies that correspond to the successive activation of distinct neural networks lasting about 350 ms. These brain states remain unaltered if T2 is presented during this period, although T2 is processed by the brain, suggesting that ongoing networks of brain activity are active for longer than early evoked-potentials and are not overwritten by an upcoming new stimulus. Intracerebral recordings demonstrate that ASG is already present at the level of ventral cochlear nucleus (vCN) and inferior colliculus and is amplified across the hierarchy in bottom-up direction. This study uncovers the extended stability of sensory-evoked brain states and long duration of ASG, and sheds light on generators of ASG and possible interactions between bottom-up and top-down mechanisms.

Children ages 9–12 years face increasing social and academic expectations that require mastery of their thoughts, emotions, and behavior. Little is known about the development of neural pathways integral to these improving capacities during the transition from childhood to adolescence. Among 234 healthy, inner-city male and female youth (speciesHomo sapiens) 9–12 years of age followed by the Columbia Center for Children's Environmental Health, we acquired diffusion tensor imaging, multiplanar chemical shift imaging, and cognitive measures requiring self-regulation. We found that increasing age was associated with increased fractional anisotropy and decreased apparent diffusion coefficient, most prominently in the frontal and cingulate cortices, striatum, thalamus, deep white matter, and cerebellum. Additionally, we found increasing age was associated with increasedN-acetyl-l-aspartate (NAA) in the anterior cingulate and insular cortices, and decreased NAA in posterior cingulate and parietal cortices. Age-associated changes in microstructure and neurometabolite concentrations partially mediated age-related improvements in performance on executive function tests. Together, these findings suggest that maturation of key regions within cortico-striatal-thalamo-cortical circuits subserve the emergence of improved self-regulatory capacities during the transition from childhood to adolescence.SIGNIFICANCE STATEMENTFew imaging studies of normal brain development have focused on a population of inner-city, racial/ethnic minority youth during the transition from childhood to adolescence, a period when self-regulatory capacities rapidly improve. We used DTI and MPCSI to provide unique windows into brain maturation during this developmental epoch, assessing its mediating influences on age-related improvement in performance on self-regulatory tasks. Our findings suggest that rapid maturation of cortico-striato-thalamo-cortical circuits, represented as progressive white-matter maturation (increasing FA and increasing NAA, Ch, Cr concentrations accompanying advancing age) in frontal regions and related subcortical projections and synaptic pruning (decreasing NAA, Ch, Cr, Glx) in posterior regions, support age-related improvements in executive functioning and self-regulatory capacities in youth 9–12 years of age.
