Twitter

Objective: The objective of this study was to examine the correlation between Twitter mentions and the number of academic citations of radiation oncology articles. Materials and Methods: We reviewed all 178 clinical manuscripts of the 2 most important radiation oncology journals and “Brachytherapy,” and all clinical manuscripts relating to radiation oncology from the top 10 impact factor oncology journals, published between January and February 2018. We collected the record of citations utilizing Scopus and Google Scholar platforms and the number of times an article was tweeted about using the “Altmetric Bookmarklet. ” χ2 test was used to compare distributions between groups and the Pearson coefficient was used for correlations between the Twitter metrics and academic citations. Results: Overall, 71% of all articles were tweeted about at least once. There was a significant correlation between the number of tweets and the number of citations in Google Scholar (r=0.55, P<0.001) and in Scopus (r=0.59, P<0.001). The 11% of articles with a prepublication Twitter “buzz” (defined as an article with ≥10 tweets before publication) had 3.6 times more citations in Scopus (mean: 14.8 vs. 4.2, P<0.001) and 2.9 times more citations in Google Scholar (17.8 vs. 6.0, P<0.001) when compared with papers with no “buzz. ” Conclusions: Presence on Twitter was correlated with the number of academic citations of an article in radiation oncology. This suggests that Twitter is being utilized by the oncology community as a platform to discuss and disseminate high impact scientific articles. The correlation between Twitter and increasing the number of citations of an article through larger dissemination and exposure requires further studies.
A bistable galloping energy harvester for enhanced concurrent wind and base vibration energy harvesting

A compact bistable galloping oscillator is proposed for enhanced power generation from concurrent wind and base vibration. The harvester consists of a D-shaped bluff body attached to a piezoelectric cantilever. Repulsive magnetic interaction is introduced between the bluff body and a fixed windward support to bring nonlinear bistability. An aeroelectro- mechanically coupled model is established and experimentally validated. Both experimental measurements and model predictions demonstrate that the synchronization bandwidth for efficient energy harvesting from concurrent wind and base vibration can be substantially extended.
Investigation of water quality using transfer learning, phased LSTM and correntropy loss

This paper aims to develop a robust dissolved oxygen (DO) prediction model of water quality to support the Hybrid Aerial Underwater Robotics System (HAUCS) project. Many challenges arise in developing such a model using the fish farm data collected, such as a small dataset containing missing data and noisy measurements taken in an irregular interval. An attempt to deal with these issues to obtain a robust prediction is discussed. Machine learning techniques, such as Long Short-Term Memory (LSTM) and Phased LSTM (PLSTM), are presented and motivated for dealing with the problem. The performances of LSTM and PLSTM against a larger and less problematic water quality dataset are first investigated. The attempts to transfer the knowledge of the models trained on this large dataset for fish farm DO data prediction through Transfer Learning are then reported. To mitigate the noisy measurement data, a loss function which can better deal with Gaussian noise: the correntropy loss is adopted. The long-range prediction experimental results using this Transfer Learning technique and the correntropy loss function are presented.
Deep Neighborhood Component Analysis for Visual Similarity Modeling

Learning effective visual similarity is an essential problem in multimedia research. Despite the promising progress made in recent years, most existing approaches learn visual features and similarities in two separate stages, which inevitably limits their performance. Once useful information has been lost in the feature extraction stage, it can hardly be recovered later. This article proposes a novel end-to-end approach for visual similarity modeling, called deep neighborhood component analysis, which discriminatively trains deep neural networks to jointly learn visual features and similarities. Specifically, we first formulate a metric learning objective that maximizes the intra-class correlations and minimizes the inter-class correlations under the neighborhood component analysis criterion, and then train deep convolutional neural networks to learn a nonlinear mapping that projects visual instances from original feature space to a discriminative and neighborhood-structure-preserving embedding space, thus resulting in better performance. We conducted extensive evaluations on several widely used and challenging datasets, and the impressive results demonstrate the effectiveness of our proposed approach.

Corn Gluten Meal as a Thermoplastic Resin: Effect of Plasticizers and Water Content

ABSTRACT Corn gluten meal (CGM) was studied to investigate the effect plasticizers and water have on its melt processing, and how this melting affects its mechanical properties. GCM containing varying amounts of water were mixed with 23% (w/w) plasticizers; (glycerol, triethylene glycol (TEG), dibutyl tartrate, and octanoic acid in a Haake bowl mixer at 80°C. The amount of water in the CGM affected the amount of torque produced in the Haake mixer. This increase in torque was correlated with how well the CGM melted in the mixer. SEM images of CGM melted in the mixer showed a more uniform homogenous structure when processed at its optimum moisture content. Glycerol, TEG, and dibutyl tartrate produced the greatest torque when the CGM contained <1% water. Octanoic acid produced the greatest torque when the CGM was processed at 8% moisture. CGM plasticized with TEG and octanoic acid were mixed at either their optimum moisture or at 9.6% moisture and then compression molded into tensile bars. The tensile streng.
Relationship between Dynamics of Structures and Dynamics of Hydrogen Bonds in Hras-GTP/GDP Complex

Hras protein is an intermediate for signals of cell proliferation and cell differentiation when Hras combines with guanosine triphosphate (GTP). In ordinary cells, GTP combined with Hras is hydrolyzed to guanosine diphosphate (GDP), and the structures of the protein-ligand complex strongly depend on hydrogen bonds. In such a system, hydrogen bonds exist between protein and ligand, between protein and water, and between ligand and water. In this study, we applied a relaxation mode analysis (RMA) to the trajectories of MD simulations for Hras-GTP/GDP to investigate the relationship between the dynamics of structures and those of hydrogen bonds. Different relaxation time of relaxation modes of Hras structures and Hras-solvent water hydrogen bonds were evident between Hras-GTP and Hras-GDP, and the results imply that the structure of Hras in Hras-GTP is stiffer than that in Hras-GDP. The method devised here and its interpretation can be applied to other systems focusing on objects with different stiffnesses.
Comparison of the Action of Macronutrients on the Expression of Appetite in Lean and Obese Human Subjects

Comparisons of the eating behavior of obese and normal-weight individuals have generally failed to identify those features that lead the obese to greater energy intakes. Certainly, there is little evidence of states of excessive hunger in the obese. Rather, subtle differences in the development of satiation and state of satiety are implicated by two experimental findings. First, the obese do not lower their liking of sweet taste stimuli following the ingestion of a glucose load. ' This absence of glucose-induced negative alliesthesia may indicate a resistance to change in the hedonic value of food stimuli. Second, cumulative intakes of obese people often describe a fixed rate of eating, with no slowing in the rate of ingestion toward the end of a In order to further explore possible differences in the appetite control system, the following studies compared the responsiveness of obese and lean individuals to preloads or small meals containing particular profiles of macronutrients. In the first study, the pleasantness (and intensity) of a sucrose solution and ratings of hunger motivation were sampled before and at 10-minute intervals for an hour after the ingestion of 50 g glucose in water or the same volume of water (200 ml). FIGURE 1 shows that this group of 11 obese subjects (mean BMI = 39) experienced no glucoseinduced negative alliesthesia, but that ingestion of glucose (188 kcal) consistently reduced hunger ratings. In contrast, glucose ingestion reduced both hunger motivation and the pleasantness of sucrose in a group of 10 lean subjects (BMI = 21). In a second study, hunger motivation was tracked in eight obese women (BMI = 38) and nine lean women (BMI = 21), before, during, and for three hours after two small (475 kcal) lunches, either high in carbohydrates (63%) or protein (54%). Obese and lean groups were characteristic in their response to caloric loading, with hunger rapidly decreasing during the meal and steadily returning during the three hours after lunch. It is of note that these profiles of intermeal and postmeal ratings of hunger motivation were similar in both groups. Furthermore, both obese and lean persons displayed sensitivity to the macronutrient content of the lunches, ratings of hunger being consistently lower after eating the high-protein lunch. When subjects were offered a self-selection meal three hours after the lunches, the reduction in subjective hunger after the protein lunch was confirmed by significant reductions in energy intake in obese (19%) and lean (22%; smallest t(7) = 3.35, p < 0.05) compared with intakes after the carbohydrate lunch (FIG. 2).
Oxidation of dissolved methane in a eutrophic, shallow lake: Lake Kasumigaura, Japan

Long‐term seasonal variations in water‐column methane oxidation were studied in the eutrophic, shallow Lake Kasumigaura, Japan. The entire water column was oxic throughout the year. Measurements were taken monthly from July 1991 to March 1996. The oxidation rates were derived from time‐course dissolved methane concentration measurements during the bottle incubation at in situ temperature. The existence of methane oxidation activity in the oxic lake water was confirmed. Methane oxidation was distinctly seasonal, with low activity from January to April and high activity from August to November. Maximum methane oxidation was observed in late summer or early autumn, when the turnover time of dissolved methane was usually shorter than half a day. Methane oxidation activity does not depend on water temperature, dissolved methane concentration, dissolved oxygen, or dissolved inorganic nitrogen. The annual average methane consumption rate was 12.3 ± 15.5 mg CH4 m−2 d−1. Methane oxidation was the dominant methane sink. consuming an annual average of 74% of dissolved methane in the water column of Lake Kasumigaura.
On the fruit-flies of the genus Dacus (s.l.) occurring in India, Burma and Ceylon

As stated in my previous paper on the Ethiopian species of Dacus , the Oriental forms of this genus show much more variation in their structural and ornamental features. They may be therefore divided into no less than five well defined genera, only one of which is common to both faunal areas. Reserving for later publication a third paper on the Oriental (and Australian) species, I will give here some notes on the classification and feeding habits of the species from British India.
Spermatogonial asynchrony in Tex14 mutant mice lacking intercellular bridges.

The existence of cytoplasmic passages between germ cells and their potential function in the control of the spermatogenic process has long been an intriguing question. Evidence of the important role of such structures, known as intercellular bridges (ICB), in spermatogenesis has been implicated by the failure of spermatogenesis in Tex14 mutant mice, which lack the ICBs, to progress past the pachytene spermatocyte stage. Using these Tex14 mutants, the present study evaluated, for the first time, the behavior and synchrony of the spermatogonial lineage in the absence of ICBs. Our data suggest that the absence of these cytoplasmic connections between cells affects the expansion of the undifferentiated type A (Aundiff) spermatogonia compartment and their transition to A1, resulting in a significant numerical reduction of differentiating A1 spermatogonia, but did not interfere with cell amplification during subsequent mitotic steps of differentiating spermatogonia from A1 through intermediate (In). However, beginning at the type B spermatogonia, the synchrony of differentiation was impaired as some cells showed delayed differentiation compared to their behavior in a normal seminiferous epithelium cycle. Thus although spermatogonial development is able to proceed, in the absence of ICBs in Tex14-/- mutants, the yield of cells, specific steps of differentiation, the synchrony of the cell kinetics, and the subsequent progression in meiosis are quantitatively lower than normal.
Cardiorespiratory fitness assessment using the PREFIT test in Italian children: a preliminary dataset.

BACKGROUND The cardiorespiratory fitness (CRF) is one of the most important indicators of the health-related physical fitness components because it reflects the efficiency of the cardiovascular and respiratory systems. To indirectly assess CRF, the original protocol of the 20mSRT was adapted in a new version suitable for children called 20mSRT-PREFIT, providing performances comparable to the standards of the European area. In fact, CRF normative values are missing in the Italian context and therefore they would be meaningful to be assessed. We aimed to determine CRF from 20mSRT-PREFIT in a small sample of Italian pre-school children and to compare the outcomes with the available European references. METHODS A convenience sample of 5-year-old pre-school children (N.=32, M/F ratio: 19/13) was freely recruited from a kindergarten of the northwest Italy. Children performed the 20mSRT-PREFIT and the number of full shuttles, exhaustion time, and maximum speed were collected to obtain CRF. RESULTS Predicted VO2max was similar between Italian male and female groups. All other outcomes originating from the 20mSRT-PREFIT were consistent with those included in the available European databases. CONCLUSIONS According to these preliminary indications, Italian pre-school children may have a CRF level equivalent to that one ascertained in other European countries. Thus, current rakings should be cautiously scrutinized, as they might inappropriately underrate Italian children's performances.
Cognitive biases in military personnel with and without PTSD: a systematic review

Abstract Background Some cognitive biases, such as excessive attention to threat, are associated with PTSD. However, they may be adaptive for military personnel; attending to threat may improve safety for deployed personnel. Aims The extent to which military personnel with vs. without PTSD differ with respect to specific cognitive biases is currently unclear. This systematic review aimed to address this question. Methods PRISMA guidelines were followed. Articles were identified using a comprehensive literature search; 21 studies (with 1977 participants) were reviewed. Results All studies were of “moderate” or “strong” quality. Military personnel with vs. without PTSD used overgeneralised language when describing autobiographical memories and demonstrated impaired performance on a modified Stroop task. Studies using dot-probe paradigms conceptualised attentional response as a dynamic process, fluctuating between bias towards and away from threat; military personnel with vs. without PTSD demonstrated greater fluctuation. Studies using visual search tasks concluded that attentional bias in PTSD involves interference (difficulty disengaging from threat) rather than facilitation (enhanced threat detection). Finally, personnel with vs. without PTSD demonstrated interpretation bias, completing ambiguous sentences with negative rather than neutral endings. Conclusion The implications for military populations and recommendations for further research and clinical practice are considered. Prospero registration PROSPERO 2018 CRD42018092235.
Validação de equações preditivas da fração indigestível da fibra em detergente neutro em gramíneas tropicais

The objective of this work was to validate the prediction equations for neutral detergent fiber indigestible fraction (iNDF) employed by the Cornell Net Carbohydrate and Protein System (Sniffen equation) and the National Research Council (Conrad's equation). A database with 114 observations taken from tropical grass, with lignin and indigestible neutral detergent fiber (iNDF) contents, was used. Comparison among predicted and observed values was accomplished by adjusting a linear regression model with predicted values as dependent variable and observed values as independent variable. The estimates supplied by Conrad's equation were different from observed values, with constant bias of +5.60 percentile points. Alteration of the exponent that composes this equation, from . 667 to . 85, controlled the bias, guaranteeing the similarity among predicted and observed values. Lack of fitness was observed on the Sniffen equation, which caused under and overestimation of the iNDF contents for lignin concentrations lower and higher than 10.4% of NDF, respectively. This behavior is supported by the absence of non-linear relationships in this equation, constituting its main element of deficiency. The bias free of Conrad equation with empirical correction enlarges the accuracy of estimation process, leading to the lower mean square of the prediction error.
A method of detecting recombinant DNAs from four lines of genetically modified maize.

A method using polymerase chain reaction (PCR) was designed for the detection of genetically modified maize (GM-maize). There are four lines of GM-maize imported from the United States, and the presence of recombinant deoxyribonucleic acid (DNA) in the maize could be detected with four pairs of specific oligonucleotide primers designed from the sequences of the newly introduced genes. The maize zein gene was also detected as an internal control. This method allows specific detection of each of Bt11, Event176, MON810 and LIBERTY by using pairs of specific primers designed to amplify a segment including part of the exogenously introduced sequence and part of the intrinsic maize sequence. The detection sensitivity was about 0.05% for Event176, MON810 and LIBERTY, and about 0.01% for Bt11. To distinguish among three insect-resistant GM-maize lines, we designed a multiplex PCR method. These three GM-maize lines were distinguishable on the basis of the expected lengths of their amplicons.
Nutrient or energy limitation on egg formation: a feeding experiment in great tits

1. We tested the hypothesis that protein availability rather than energy availability constrains egg formation in great tits (Parus major L.) by providing them with two food supplements of different protein content in the prelaying and laying period of 1991 and 1992. 2. Timing of breeding, clutch size and egg size did not differ between the two food supplements. Thus, the hypothesis that a low protein content of supplement restricts laying in great tits cannot be supported. 3. Food supplementation, independent of food type and year, led to an advancement of laying by 5.6 days. Average clutch size of supplemented birds, corrected for laying date and year, was 0.55 eggs above the population average. 4. Supplementary fed great tits did not breed more successfully than controls. This suggests that by adding food early in laying, birds were induced to lay at a less favourable time and/or produced clutches that were too large to care for successfully under normal food condition. Thus food early in the season might not only energetically restrict laying birds, but also provide clues about future conditions during chick rearing. 5. The comparison of results of published supplemental feeding experiments shows that the birds responded more strongly to additional feeding in poor environments. Almost two-thirds of the variation in changes of clutch size due to experimental treatment can be explained by year quality. Thus, only in poor environments do reproductive traits seem to be limited by energy availability early in the season, but other factors become more important in good environments [KEYWORDS: clutch size, egg formation, food quality, food supplementation, Parus major]
Failures of 13-Valent Conjugated Pneumococcal Vaccine in Age-Appropriately Vaccinated Children 2–59 Months of Age, Spain

Vaccination with the 13-valent conjugated pneumococcal disease (PCV13) has reduced invasive pneumococcal disease (IPD), but there have been reports of vaccine failures. We performed a prospective study in children aged 2–59 months who received diagnoses of IPD during January 2012–June 2016 in 3 pediatric hospitals in Catalonia, Spain, a region with a PCV13 vaccination coverage of 63%. We analyzed patients who had been age-appropriately vaccinated but who developed IPD caused by PCV13 serotypes. We detected 24 vaccine failure cases. The serotypes involved were 3 (16 cases); 19A (5 cases); and 1, 6B, and 14 (1 case each). Cases were associated with children without underlying conditions, with complicated pneumonia (OR 6.65, 95% CI 1.91–23.21), and with diagnosis by PCR (OR 5.18, 95% CI 1.84–14.59). Vaccination coverage should be increased to reduce the circulation of vaccine serotypes. Continuous surveillance of cases of IPD using both culture and PCR to characterize vaccine failures is necessary.
Cardiac function modulates endocardial cell dynamics to shape the cardiac outflow tract

ABSTRACT Physical forces are important participants in the cellular dynamics that shape developing organs. During heart formation, for example, contractility and blood flow generate biomechanical cues that influence patterns of cell behavior. Here, we address the interplay between function and form during the assembly of the cardiac outflow tract (OFT), a crucial connection between the heart and vasculature that develops while circulation is under way. In zebrafish, we find that the OFT expands via accrual of both endocardial and myocardial cells. However, when cardiac function is disrupted, OFT endocardial growth ceases, accompanied by reduced proliferation and reduced addition of cells from adjacent vessels. The flow-responsive TGFβ receptor Acvrl1 is required for addition of endocardial cells, but not for their proliferation, indicating distinct modes of function-dependent regulation for each of these essential cell behaviors. Together, our results indicate that cardiac function modulates OFT morphogenesis by triggering endocardial cell accumulation that induces OFT lumen expansion and shapes OFT dimensions. Moreover, these morphogenetic mechanisms provide new perspectives regarding the potential causes of cardiac birth defects. Highlighted Article: Blood flow and cardiac contractility generate crucial cues that drive the essential cellular mechanisms responsible for creating the specific dimensions of the cardiac outflow tract.
