The changes of vitamin C , chlorophyll , carotene , xanthophylls content and the antiradicalic activity of sunflower sprouts after selenium treatment

In this paper we present some of the consequences of the selenium treatment on sunflower sprout. We determined: vitamin C, chlorophyll pigments, xanthophylls and carotens content and antiradical activity (AA). Sunflower sprouts were obtained by sunflower seeds germination in presence of sodium selenite (5 and 10 ppm Se) – experimental group, and water – control group. The methods used in our study were: Vitamin C – by iodometric method, AA – by DPPH method, chlorophyll pigments, xanthophylls and carotenes – by spectrophotometric method. The selenium treatment has led to increasing all of these parameters in experimental group, comparing to control group. The selenium treatment of sunflower seeds improves the nutritive quality of sunflower sprouts with beneficial effect on the human consumption.
Comparison of hand-sewn versus mechanical esophagogastric anastomosis in esophageal cancer

Abstract Background: Many studies have been conducted to compare the hand-sewn and mechanical staples in esophageal cancer (EC) patients who received esophagogastric anastomosis. However, the results remain controversial. Hence, the purpose of the meta-analysis is to evaluate the impact of different anastomosis methods on the early and long-term outcomes. Methods: We will perform a systematic electronic search of the PubMed, Embase, Cochrane Library, Web of Science for relevant articles published in English language. Pooled odds ratios will be calculated for the effect on discrete variables including anastomotic leakage, anastomotic strictures, 30-day mortality, quality of life, cardiac and pulmonary complications. The weighted mean difference was calculated for the effect size on continuous variables such as operative time and bleeding amount. We will use the software Review Manager 5.3 and STATA 14.0 to perform the meta-analysis to calculate the data synthesis. Results: The review will provide a high-quality synthesis of current evidence of the impact of different anastomosis methods on postoperative course in ECs after esophagectomy. The results will be published in a peer-reviewed journal. Conclusion: This systematic review and meta-analysis will compare the different anastomosis methods in EC patients. The results will better offer some specific suggestions for esophagogastric anastomosis. PROSPERO registration number: This systematic review protocol has been registered in the PROSPERO network (No. CRD 42019109523).
Ju l 2 01 9 Composing Diverse Policies for Temporally Extended Tasks

Temporally extended and sequenced robot motion tasks are often characterized by discontinuous switches between different types of local dynamics. These change-points can be exploited to build approximate models of the interleaving regions, which in turn allow the design of region-specific controllers. These can then be combined to create the initiation state-space of a final policy. However, such a pipeline can become challenging to implement for combinatorially complex, temporarily extended tasks especially so when sub-controllers work on different information streams, time scales and action spaces. In this paper, we introduce a method that can compose diverse policies based on scripted motion planning, dynamic motion primitives and neural networks. In order to do this, we extend the options framework to introduce a per-option dynamics module and a global function that evaluates a goal metric. Additionally, we can leverage expert demonstrations to sequence these local policies, converting the learning problem in hierarchical reinforcement learning to a planning problem at inference time. We first illustrate the core concepts with an MDP benchmark, and then with a physical gear assembly task solved on a PR2 robot. We show that the proposed approach successfully discovers the optimal sequence of policies and solves both tasks efficiently.
jmbReview Wolbachia Sequence Typing in Butterflies Using Pyrosequencing

Wolbachia is an obligate intracellular symbiotic bacterium. It belongs to the order Rickettsiales and is known to infect numerous species of arthropods and nematodes. The bacterium is known to manipulate the reproduction of its insect hosts via cytoplasmic incompatibility, parthenogenesis, male-killing, or feminization [8, 18, 30, 31]. Wolbachia species are classified into 11 (A–K) supergroups [22] based on multilocus sequence typing (MLST) and Wolbachia surface protein (WSP) typing [2]. The standard MLST system for Wolbachia determines a sequence type (ST) based on the combination of alleles for five conserved housekeeping genes (ftsZ, gatB, coxA, hcpA, and fbpA). The WSP typing system determines STs using four hypervariable regions (HVRs) of WSP: HVR1 (aa 52 to 84), HVR2 (85 to 134), HVR3 (135 to 185), and HVR4 (186 to 222) [1]. A host can be infected with a single strain of Wolbachia, or multiple strains, as has been observed in a wide range of insects [13, 20, 21]. Classical MLST can be used for the universal characterization of Wolbachia, but its application is currently limited to hosts infected with a single strain of Wolbachia [2]. To assess the diversity of Wolbachia in insects infected with multiple strains, sequencing of the wsp gene is generally conducted [32]. Amplification of ST-specific regions is also used, but this method has limited application because the design of specific primers is only possible after a strain’s sequence is known. Improved methods for determining STs in insects infected with multiple strains would contribute to understanding Wolbachia diversity.

A Ten-Step Process for Developing Teaching Units.

Curriculum design and implementation can be a daunting process. Questions quickly arise, such as who is qualified to design the curriculum and how do these people begin the design process. According to Graves (2008), in many contexts the design of the curriculum and the implementation of the curricular product are considered to be two mutually exclusive processes, where a long chain of specialists including policy makers, methodologists, and publishers produce the curriculum in a hierarchical process, at the end of which lies the teacher.

The Oil Radish Growth Dataset for Semantic Segmentation and Yield Estimation

Data sharing in research is important in order to reproduce results, develop global models, and benchmark methods. This paper presents a dataset containing image and field data from a field plot experiment with oil radish (Raphanus sativus L. var oleiformis) as catch crop after spring barley. The field data consists of fresh weight, dry weight, Carbon content and Nitrogen content from multiple weekly plant samples collected from the plots. The image data consists of images collected weekly prior to the plant samples. A subset of the images corresponding to the plant sampling areas have been annotated pixelwise. In addition to the image and field data, weather data from the growing period is also included in the dataset. The dataset is accompanied by two challenges: 1) semantic segmentation of crops and 2) oil radish yield estimation. The former challenge focuses on data image, while the latter focuses on the field data. Baseline methods and results are provided for both challenges.
Can differences in Patient Reported Outcome Measures be attributed to providers ?

Patient Reported Outcome Measures are now collected routinely from patients undergoing four major surgical procedures in the NHS in England. Variations between providers are being interpreted as variations in their achievements. However, these variations also represent differences between providers in both observable and unobservable differences in case mix of patients and true random variation. Using the national PROMs data and two other datasets containing patient reported outcomes, we consider whether these variations can be attributed to providers with confidence. We find that provider variation is reduced substantially by allowing for observable case-mix, particularly baseline health, by increasing the number of follow-up observations on patients, by allowing for patient-level unobservable heterogeneity, and by estimating provider variation on a greater number of patients. These findings suggest caution is warranted in interpreting variations in short-term PROMs between providers. Paper presented to CES-HESG, Aix-en-Provence 11-13 January 2012
The Defense Mechanism of Cabbage Plant Against Phloem-Sucking Aphid ( Brevicoryne brassicae L . )

The current work aims to study the defense mechanism of cabbage plant ( Brassica olereacea var. capitata) against phloem sucking aphid ( Brevicoryne brassicae L.). A significant reduction in the percentage of epicuticular wax, dry weight, sugar, amino acids levels were found with aphid feeding. Furthermore, aphid herbivory elicit an effect on the uptake of some nutrient elements such as P, K, Ca, Mg and Fe. Insect feeding significantly increased the uptake of Ca and K while, 2+ + the other measured elements were markedly decreased. In addition lipid peroxidation measured as malondialdehyde was markedly increased after insect feeding. The levels of antioxidant compounds (glutathione, ascorbic acid, carotenoids and phenols) were changed in response to aphid feeding. The level of ascorbic acid was significantly increased by infestation. The oxidative enzyme activities (superoxide dismutase, ascorbate peroxidase, ascorbate oxidase) were significantly reduced while polyphenol peroxidase and oxidase activities were enhanced by insect infestion. Moreover, total soluble protein content of the infested senscing cabbage leaves was markedly declined. No qualitative changes were found in the polypeptide pattern of both healthy and infested plants. However, quantitative differences in polypeptides were obtained in control and infested plants. The findings suggest that aphid feeding probably results in oxidative stress in cabbage. Ascorbic acid, proline, phenol peroxidases, oxidases as well as Ca and K may play a role in the defense mechanism of 2+ + aphid infested cabbage leaves, thereby delay their death.
C L ] 2 7 A pr 2 01 5 Neural Responding Machine for Short-Text

We propose Neural Responding Machine (NRM), a neural networ k-based response generator for Short-Text Conversation. NRM takes the general encoder-de coder framework: it formalizes the generation of response as a decoding process based on the lat ent representation of the input text, while both encoding and decoding are realized with recurren t n ural networks (RNN). The NRM is trained with a large amount of one-round conversation dat a collected from a microblogging service. Empirical study shows that NRM can generate gramma tically correct and content-wise appropriate responses to over 75% of the input text, outperf orming state-of-the-arts in the same setting, including retrieval-based and SMT-based models.

2 A Demand Response Program Using Proportional Allocation Mechanism with Tight PoA Bound

Motivated by climate change and sustainability, and the resulting need to decarbonize the electricity sector, there is a major global movement toward largescale integration of renewable energy, i.e., wind and solar, into the existing power grid. The inherent variability of wind and solar energy production poses a major challenge in achieving these goals. The problem becomes more challenging as we consider issues of competitive markets, low cost and high reliability. In the last few years, we have been working on new systems and control problems that arise from these considerations. In this paper, we will present some highlights of our work on developing demand response methods using distributed control and bounding the loss of efficiency in these methods.
UNDERSTANDING PARTISAN CUE RECEPTIVITY 1 Understanding Partisan Cue Receptivity : Tests of Predictions from the Bounded Rationality and Expressive Utility

Why do citizens rely on partisan cues when forming political judgments? We assessed the relative importance of two motives for partisan cue-following using a series of survey experiments.1 We found no support for the bounded rationality hypothesis that cue receptivity is highest among citizens with low cognitive resources. Meanwhile, we found mixed support for the expressive utility hypothesis that cue receptivity is highest among people with both a strong partisan social identification and high cognitive resources. The strength of this latter evidence varied across studies, cognitive resource measures, and cue condition comparisons. The results suggest that partisan cue receptivity more often involves an effort to harness cognitive resources for the goal of identity expression than an effort to compensate for low cognitive resources.
German modal verbs through cognitive linguistics insights

This study examined the acquisition patterns of the prototypical and epistemic semantic meanings of German modals. It investigated whether different instructional approaches (cognitive instruction approach based on force dynamics and metaphoric extensions, traditional translation based instruction) have the potential to foster modal verbs acquisition, and which of the two approaches was more effective. Thirty-three, fourth semester learners of German as a foreign language were subjected to one of the experimental conditions. Findings were compared to a control condition, which did not receive any instruction. Learning gains were measured by means of a multiple choice meaning recognition test that assessed students’ gains of receptive knowledge of the prototypical and epistemic senses of German modals. Results revealed that when students received cognitive instruction, they gained greater prototypical and epistemic semantic knowledge when compared to the students who received traditional translation based instruction or were part of the control condition. Most importantly, it was shown that the cognitive instruction approach had greater effect on meaning retention of modal verbs senses. German Journal Volume 1, 2018
Guidelines for Tall Buildings Development

Tall buildings’ implementation has often lacked urban design and architectural guidance. There are many examples of tall buildings that have been inappropriately located, designed, and built, and consequently dissatisfaction with high-rise development is wide-spread. This paper attempts to provide extensive urban and architectural guidelines in order to manage cityscape and to ensure safe and healthy living. Through recommendations on design and layout of tall buildings and open spaces the guidelines seek enhancing the visual experience, improving the microclimate conditions, and fostering active social life. These guidelines help in providing enjoyable urban experiences through the examination of spatial relationships, human scale, genius loci, perceptual characteristics, local identity, built heritage, economic activities, and social life.
Applying a Taxonomy as a Framework to Understand Co-Creation as an Approach to Information Systems Development

Our paper investigates how co-creation as an information systems development (ISD) approach is performed. Our empirical practice study of co-creation for and with youths involved in developing a digital game on a social media platform in a not-for-profit environment contributes to broadening the perspective on ISD and co-creation research. We apply an established taxonomy of co-creation and demonstrate how the taxonomy can be used as a framework to understand what co-creation is, how, when and where it can be performed as an instance of ISD practice. As a result we demonstrate the value and the shortcomings of the taxonomy.

The simulation tests the validity and correctness of the algorithm. Copyright © 2014 IFSA Publishing, S. L.
Of eyes and embryos: subfunctionalization of the CRX homeobox gene in mammalian evolution

ETCHbox genes are fast-evolving homeobox genes present only in eutherian (placental) mammals which originated by duplication and divergence from a conserved homeobox gene, Cone-rod homeobox (CRX). While expression and function of CRX are restricted to the retina in eutherian mammals, ETCHbox gene expression is specific to preimplantation embryos. This dramatic difference could reflect the acquisition of new functions by duplicated genes or subfunctionalization of pleiotropic roles between CRX and ETCHbox genes. To resolve between these hypotheses, we compared expression, sequence and inferred function between CRX of metatherian (marsupial) mammals and ETCHbox genes of eutherians. We find the metatherian CRX homeobox gene is expressed in early embryos and in eyes, unlike eutherian CRX, and distinct amino acid substitutions were fixed in the metatherian and eutherian evolutionary lineages consistent with altered transcription factor specificity. We find that metatherian CRX is capable of regulating embryonically expressed genes in cultured cells in a comparable way to eutherian ETCHbox. The data are consistent with CRX having a dual role in eyes and embryos of metatherians, providing an early embryonic function comparable to that of eutherian ETCHbox genes; we propose that subfunctionalization of pleiotropic functions occurred after gene duplication along the placental lineage, followed by functional elaboration.
Patterns of water in light

The intricate patterns emerging from the interactions between soliton stripes of a two-dimensional defocusing nonlinear Schrödinger (NLS) model with a non-local nonlinearity are considered. We show that, for sufficiently strong non-locality, the model is asymptotically reduced to a Kadomtsev–Petviashvilli-II (KPII) equation, which is a common model arising in the description of shallow water waves, as such patterns of water may indeed exist in light (this non-local NLS finds applications in nonlinear optics, modelling beam propagation in media featuring thermal nonlinearities, in plasmas, and in nematic liquid crystals). This way, approximate antidark soliton solutions of the NLS model are constructed from the stable KPII line solitons. By means of direct numerical simulations, we demonstrate that non-resonant and resonant two- and three-antidark NLS stripe soliton interactions give rise to wave configurations that are found in the context of the KPII equation. Thus, our study indicates that patterns which are usually observed in water can also be found in optics.
Ionic liquid-modified MCM-41-polymer mixed matrix membrane for butanol pervaporation

Because of the preferential butanol selectivity of some ionic liquids (ILs), an increasing amount of research has appeared regarding their application in butanol separation. In this research, two ionic liquids, namely, 1-ethyl-3-vinylimidazolium bis[(trifluoromethyl)sulfonyl]imide ([EVIM][Tf2N], IL1) and N-octyl-pyridinium bis[(trifluoromethyl)sulfonyl]imide ([OMPY][Tf2N], IL2), were applied to modify a mesoporous molecular sieve MCM-41. The IL-modified MCM-41 samples were characterized by XPS, BET, XRD, SEM and TEM. The ionic liquid-modified MCM-41 was incorporated into the polymer PEBA to prepare mixed matrix membranes to study the influences of the filling of IL-modified MCM-41 and operating conditions on the performance of the mixed matrix membrane for butanol pervaporation. The results indicated that the pervaporation performance of the PEBA membrane was enhanced by the incorporation of IL-modified MCM-41. When the temperature of the feeding liquid was 35°C and the mass fraction of butanol was 2.5 wt%, the 5% MCM-41-IL2-PEBA membrane showed a permeation flux of 421.7 g m−2 h−1 and a separation factor of 25.4. The permeation flux and the separation factor of the membrane increased as the temperature of the feeding liquid increased. The results of the long-period experiment suggested that the 5% MCM-41-IL2-PEBA membrane exhibited high stability within 100 h of operation.
