A Simple and Heuristic Model of Tag Recommendation

Compared to the high computational complexity of many tag recommenders, a simple and heuristic approach of tag recommendation is proposed, based on tag user and item tag co-occurrences in parallel. Firstly, we use aspect model PLSA to set up a probabilistic model. We find that the probability of the recommended tags to an item for a specific user is determined by two factors: the preferences in choosing tags for the user and the tags reflecting the feature of the item. Then we immerge the two factors into a unified representation. The experiments show that our approach not only has better reliability and precision, but also is very simple and more practical than other algorithms.
Effectiveness of low sodium diets for recycling of egg production type hens.

Egg type hens were recycled by the use of low sodium diet treatments compared to a conventional forced-molt procedure and an unrecycled control. Use of a low sodium diet containing . 02 to . 06% sodium for 6 weeks with reduction in daily photoperiod resulted in improvements in egg production, egg specific gravity, and albumen thickness similar to those of a forced-molt group in three separate experiments. Egg production was increased 11 to 13%, egg specific gravity was increased by . 002 to . 004, and albumen thickness was increased by 2 to 8 Haugh units over the 32-week posttreatment period for both treatments. Hens fed the low sodium diet for 3.5 or 4 weeks did not respond as favorably as hens fed this diet for 6 weeks. Eight weeks on the low sodium diet did not further improve performance. Results comparable to the forced-molt procedure were achieved with a decline in egg production at . 03 to . 07% sodium in the diet, a decline in feed intake at . 03 to . 07% sodium, a loss in body weight at . 03 to . 10% sodium, and an increase in molt score at . 03 to . 11% sodium during the experimental period. During the posttreatment period, results comparable to the forced-molt procedure were obtained for egg production increase at . 03 to . 08% sodium, for egg specific gravity increase at . 03 to . 12% sodium, and for egg albumen thickness increase at . 03 to . 12% dietary sodium. Mortality was unchanged.
Detached/Contactless Growths, Reduced Melt Convection and Its Effect on the Device Grade Substrates of SB-Based Crystals Grown By VDS on Earth

Vertical directional solidification (VDS) under the controlled growth conditions and parameters has been operated to solidify antimonide (Sb) based bulk crystals for the entire detached/contactless growths. In ground experiments, Crystal qualities have been studied in VDS, under the effect of reduced melt convection. Recent detached crystals grown by VDS have been studied for quality identifications: InSb1-x Bix, InSb1-xNx, GaSb1-xSex, and GaSb1-xMnx. Detachment is a key factor for the dopant distribution in microhomogeneities under terrestrial condition. Dopant distributions along the transverse and longitudinal axis of entire detached ingots have been measured. Crystal properties had confirmed that the homogeneous substrates, higher structural quality and reduction in convection into melt, at the macro and micro level. VDS crystal properties are analogous to the crystals grown in microgravity. Methodology of solidification seems to be the promising technology for the device grade bulk crystals. VDS crystal growth system has prospects as the commercially profitable system.

Differentiation of Clear Cell Renal Cell Carcinoma From Other Renal Cortical Tumors by Use of a Quantitative Multiparametric MRI Approach.

OBJECTIVE The purpose of this study was to develop a quantitative multiparametric MRI approach to differentiating clear cell renal cell carcinoma (RCC) from other renal cortical tumors. MATERIALS AND METHODS This retrospective study included 119 patients with 124 histopathologically confirmed renal cortical tumors who underwent preoperative MRI including DWI, contrast-enhanced, and chemical-shift sequences before nephrectomy. Two radiologists independently assessed each tumor volumetrically, and apparent diffusion coefficient values, parameters from multiphasic contrast-enhanced MRI (peak enhancement, upslope, downslope, AUC), and chemical-shift indexes were calculated. Univariate and multivariable logistic regression analyses were performed to identify parameters associated with clear cell RCC. RESULTS Interreader agreement was excellent (intraclass correlation coefficient, 0.815-0.994). The parameters apparent diffusion coefficient (reader 1 AUC, 0.804; reader 2, 0.807), peak enhancement (reader 1 AUC, 0.629; reader 2, 0.606), and downslope (reader 1 AUC, 0.575; reader 2, 0.561) were significantly associated with discriminating clear cell RCC from other renal cortical tumors. The combination of all three parameters further increased diagnostic accuracy (reader 1 AUC, 0.889; reader 2, 0.907; both p ≤ 0.001), yielding sensitivities of 0.897 for reader 1 and 0.897 for reader 2, and specificities of 0.762 for reader 1 and 0.738 for reader 2 in the identification of clear cell RCC. With maximized sensitivity, specificities of 0.429 and 0.262 were reached for readers 1 and 2, respectively. CONCLUSION A quantitative multiparametric approach statistically significantly improves diagnostic performance in differentiating clear cell RCC from other renal cortical tumors.
Finding the maximum clique in massive graphs

Cliques refer to subgraphs in an undirected graph such that vertices in each subgraph are pairwise adjacent. The maximum clique problem, to find the clique with most vertices in a given graph, has been extensively studied. Besides its theoretical value as an NP-hard problem, the maximum clique problem is known to have direct applications in various fields, such as community search in social networks and social media, team formation in expert networks, gene expression and motif discovery in bioinformatics and anomaly detection in complex networks, revealing the structure and function of networks. However, algorithms designed for the maximum clique problem are expensive to deal with real-world networks. In this paper, we devise a randomized algorithm for the maximum clique problem. Different from previous algorithms that search from each vertex one after another, our approach RMC, for the randomized maximum clique problem, employs a binary search while maintaining a lower bound ωc and an upper bound [EQUATION] of ω(G). In each iteration, RMC attempts to find a ωt-clique where [EQUATION]. As finding ωt in each iteration is NP-complete, we extract a seed set S such that the problem of finding a ωt-clique in G is equivalent to finding a ωt-clique in S with probability guarantees (≥1−n−c). We propose a novel iterative algorithm to determine the maximum clique by searching a k-clique in S starting from k = ωc +1 until S becomes [EQUATION], when more iterations benefit marginally. As confirmed by the experiments, our approach is much more efficient and robust than previous solutions and can always find the exact maximum clique.
Child neglect and abuse: a global glimpse within the framework of evidence perspective

AIM This systematic review was conducted in order to integrate evidence-based knowledge and experience related to child neglect and abuse into the nursing literature. BACKGROUND The negative and intense effects of neglect and abuse on an individual can last into adulthood. Nurses who are in close contact with such cases have an important role to play in detecting child neglect and abuse and supporting the families involved. When nurses fulfil this role, it is important that evidence-based information and interventions are known to ensure that the process is a healthy one. DATA SOURCES Medline/Pubmed and Cochrane Library databases, from 2012 to 2016. REVIEW METHODS The PRISMA guide, a basic search algorithm, was used as a basis for the review. RESULTS This systematic research involved 32 articles that met the criteria. When the characteristics of the studies were examined, it was found that one study dealt with physical abuse, seven studies dealt with sexual abuse, 21 studies with neglect and abuse and three studies with all abuse types. It was also found that 16% addressed intervention, 22% addressed the relationship between abuse and other factors, 31% addressed prevention and 31% addressed the defining dimension. CONCLUSIONS It has been found that, in general, all types of negligence and abuse are studied together and that nurses lack the knowledge and skills needed to assess childhood neglect and abuse. IMPLICATIONS FOR NURSING AND HEALTH POLICIES Nurses have a critical role to play in identifying the dark spots and associated factors in the story of individuals because they are health professionals who are in close contact with patients. It is recommended that guidelines be developed and used in the diagnosis and treatment of abuse and neglect. Thus, in these cases, the standardization of care will be achieved.

The adverse effects of oral desmopressin lyophilisate (MELT): personal experience on enuretic children.

Objective The aim of this study was to evaluate adverse effects of oral desmopressin lyophilisate (MELT) in enuretic children. Material and methods We enrolled 260 children with nocturnal enuresis (NE) referred to the Pediatric Service, 'Campus Bio-Medico' University of Rome, from April 2014 to April 2017 in the study, of these 23 were excluded. The study was characterized by 2 phases. During Phase 1 a careful patient's medical history was obtained and physical examination was performed. After 3 months of treatment with MELT (Minirin/DDAVP®) at the dose of 120 mcg a day, a micturition diary was kept, adherence to therapy and any possible adverse effects were checked during the Phase 2. The study was carried out in compliance with the Helsinki Declaration. Results Among 237 patients included in the study 11 male and 6 female (n=17; 7.2%) patients with a mean age 10.06±2.49 years, reported 22 adverse effects, with an absolute risk of 7.17%. In particular, 5 neurological symptoms, 3 gastrointestinal effects, 4 sleep disturbances, 8 psycho-behavioral disorders, 2 symptoms of fatigue were reported. Conclusion In our study MELT with its higher bioavailability guaranteed lower frequency of adverse effects which resolved spontaneously and rapidly. The MELT formulation actually represents the first line and safe treatment for the NE.
SITUATION-AWARE SPOKEN LANGUAGE PROCESSING

Our goal is to create situation-aware speech systems which integrate knowledge of relevant aspects of the current state of the world into spoken language learning, understanding and generation. Awareness of the situation is achieved by extracting salient information about the speaker’s world from sensors including cameras, touch sensors, and microphones. A key challenge in this approach is to design and integrate linguistic and non-linguistic representations. This paper presents an implemented system which learns to understand and generate spoken utterances grounded in camera-derived visual semantics [18, 19]. Current work on a more sophisticated cross-modal language learning system is also introduced.
Comparison and visualisation of agreement for paired lists of rankings

Abstract: Output from analysis of a high-throughput ‘omics’ experiment very often is a ranked list. One commonly encountered example is a ranked list of differentially expressed genes from a gene expression experiment, with a length of many hundreds of genes. There are numerous situations where interest is in the comparison of outputs following, say, two (or more) different experiments, or of different approaches to the analysis that produce different ranked lists. Rather than considering exact agreement between the rankings, following others, we consider two ranked lists to be in agreement if the rankings differ by some fixed distance. Generally only a relatively small subset of the k top-ranked items will be in agreement. So the aim is to find the point k at which the probability of agreement in rankings changes from being greater than 0.5 to being less than 0.5. We use penalized splines and a Bayesian logit model, to give a nonparametric smooth to the sequence of agreements, as well as pointwise credible intervals for the probability of agreement. Our approach produces a point estimate and a credible interval for k. R code is provided. The method is applied to rankings of genes from breast cancer microarray experiments.
Effects of rotational speed of driving roll on microstructure evolution during hot ring rolling of as-cast 42CrMo steel

The evolution rules and reasonable regulation of the microstructure of the as-cast ring blank material is the main bottleneck question for the development of the new casting-rolling composite forming technology.The rotational speed of the main roll is one of the key factors influencing the recrystallization behavior and microstructure of the as-cast ring blank material.In this paper,we first established a coupled macro-micro FE model of hot ring rolling for as-cast 42CrMo steel under ABAQUS software environment,then numerically revealed dynamic recrystallization(DRX) behavior of as-cast ring blank material,and lastly clarified the effect rules and mechanism of the rotational speed of the main roll on grain size and its distribution.The results show that:(1) The DRX percentages is high in the inner and outer layers of the ring leading to refined grain while relatively low in the middle layer of the ring resulting in coarse grain;(2) the DRX percentage increases while the average grain size decreases with the increase of the rotational speed of the main roll;and(3) the rotation speed of the main roll has negligible effect on the uniformity of the distribution of the average grain size.
Application of Spray Drying Technique for Flowability enhancement of Divalproex Sodium

Abstract Background Tablets and capsules are the most accepted and widely used solid dosage forms in the medical therapy. Flow property of the powders is playing a key role in the various pharmaceutical fields especially in the fomulation of tablets and capsules. The high hygroscopic crystalline structure of anhydrous Divalproex sodium (DVX) makes it to be appear as waxy white ﬂakes with almost no powder flowability which cause serious problems during the tabletting and capsule filling procedures. Purpose The main objective of this study was to improve the flowability of DVX powder. Methods DVX was mixed with mannitol or lactos in different ratios, dissolved in water and differet binary mixtures of ethanol:water, and finally spray dried with different spray drying conditions. Particle size and powders morphology were assessed by Scanning Electron Microscopy (SEM). The poweder flowability was assessed by measurmet of Hausner ratio (HR), Carr’s index (CI) and angle of repose (AOR) indexes. Furthermore, the content uniformity of DVX in spray-dried powders was determined by using a validated HPLC technique. Results The results showed that spray drying technique improved DVX flowability by forming spherical particles with narrow size distribution AOR value of DVX was decrease from not flowable to 36.1° in spray dried solid dispersion indicating the improvmet of powder flowability from very poor to fair/good condition. Conclusion Findings suggest that the spray drying technique improves DVX flowability and may pave the way for improvement in the tabletting procedure of DVX.
Article in press-uncorrected proof Antioxidant activity of extracts from the bark of Chamaecyparis lawsoniana ( A . Murray )

The bark of Chamaecyparis lawsoniana (A. Murray) Parl. was extracted with methanol and sequentially partitioned with n-hexane, ethyl acetate, n-butanol and deionized water. The antioxidant activities of the four extracts were evaluated using the DPPH• and ABTS methods. The total phenolic content of the extracts was determined using the Folin-Ciocalteu method and expressed as gallic acid equivalents (GAE). Butylated hydroxytoluene was used as a positive control in the radical-scavenging activity tests. All the bark extracts showed significant radical-scavenging activity. In the ABTS assay, n-butanol extracts exhibited the strongest radical-scavenging activity, followed by ethyl acetate, water, and n-hexane extracts. The greatest total phenolic content was 428.54 mg GAE per gram of dry extract and was detected in the n-butanol extract, followed by the ethyl acetate and n-hexane extracts. The antioxidant activities correlate with the amount of phenolics present in these extracts. The ethyl acetate and n-butanol extracts were rich in phenolics and may represent a good source of antioxidants.
4 Epitaxial Graphene on SiC ( 0001 ) : More Than Just

The growth of graphitic layers by the sublimation of Si from SiC substrates has been known since 1975 (van Bommel et al., 1975). The electronic properties of these materials are recently found to be similar to that of isolated graphene sheets (Berger et al., 2006; Castro Neto et al., 2009; Miller et al., 2009). Due to its compatibility with current standard semiconductor device fabrication technology, this process offers additional benefit of large-scale production of wafer-sized materials to facilitate the development of graphene electronics (Berger et al., 2004; Kedzierski et al., 2008; Lin et al., 2010). Currently, 4Hand 6H-SiC polytypes are commercially available for the growth of epitaxial graphene. Because of the mismatch with the SiC, the physical and electronic properties of graphene films strongly depend on the polarity of the substrate. On the (000-1) C-face, graphene films typically grow in multiple layers with a “twisted” interface, which leads to the decoupling between different layers, and a carrier mobility comparable to that of exfoliated graphene (Hass et al., 2008a; Orlita et al., 2008; Sprinkle at al., 2009). On the (0001) Si-face, on the other hand, the growth is self-limiting, where more uniform wafer-sized graphene films with controlled number of layers has been grown epitaxially (Emtsev et al., 2009). The graphitization has been known to start with a (6√3x6√3) (denoted “6√3” hereafter) structure, which remains at the interface during the growth of subsequent layers (van Bommel et al., 1975; Hass et al., 2008b). The interactions of this interfacial layer with the graphene above and SiC(0001) substrate below lead to giant inelastic tunnelling in scanning tunnelling spectroscopy (STS) (Červenka et al., 2010); modification of the dispersion about the Dirac point (Bostwick et al., 2007(a,b); and even gap opening in angleresolved photoemission spectroscopy (ARPES) a property crucial for its use in electronic devices – but found only for epitaxial graphene on the Si-face, and absent for the C-face and exfoliated graphene (Novoselov, 2007; Zhou et al., 2007). Despite its impact on the electronic properties of graphene, the atomic structure of the 6√3 layer remains controversial. Earlier studies have suggested that it consists of a graphene honeycomb layer weakly bonded to the SiC (1x1) surface (van Bommel et al., 1975; Tsai et al., 1992) or Si-rich interface layer (Northrup & Neugebauer, 1995; Forbeaux et al., 1998). More recent work indicates covalent bonding at the interface to the SiC (Seyller et al., 2008; Emtsev et al., 2008). Furthermore, most calculations, which are based on defect-free graphene covalently bonded to the SiC(0001) (1x1), indicate a metallic 6√3 layer (Kim et al., 2008; Varchon et al., 2007), contrary to a semiconducting surface around K as observed in
An Evaluation of the Honey Bee (Hymenoptera: Apidae) Safety Profile of a New Systemic Insecticide, Flupyradifurone, Under Field Conditions in Florida

Abstract Flupyradifurone (Sivanto) is a novel systemic insecticide from the butenolide class developed by Bayer. Based on available data (USEPA 2014), this insecticide appears to have a favorable safety profile for honey bee colonies. As a result, the label permits the product to be applied during prebloom and bloom in various crops, including citrus, except when mixed with azole fungicides during the blooming period. We placed 24 honey bee (Apis mellifera L.) colonies adjacent to eight flowering buckwheat (Fagopyrum esculentum Moench) fields that either had been sprayed with the maximum label rate of flupyradifurone or with water only (control fields), with three colonies placed adjacent to each field. We conducted colony strength assessments during which the number of adult bees, eggs, uncapped brood cells, capped brood cells, food storage cells, and weights of honey supers and brood chambers were determined prior to, during, and after the flowering period. We also analyzed bee-collected pollen and nectar for flupyradifurone residues. Overall, there were no differences in any colony strength parameter for colonies placed at control and flupyradifurone-treated buckwheat fields. Residue analyses showed that pollen (x = 565.8 ppb) and nectar (x = 259.4 ppb) gathered by bees on fields treated with flupyradifurone contained significantly higher flupyradifurone residues than did bee bread and unprocessed nectar collected by bees from control fields (75% of samples <LOD). Within the conditions set forth by our experimental design, our collective data suggest no adverse effects of flupyradifurone on honey bee colonies when following label directions.
Assessment of high performance HAN-monopropellants

There are several challenges presented with operating high performing monopropellants. Generally, along with high specific impulse, high performing monopropellants have high combustion temperatures. If a simple and reliable catalytic ignition approach is desired for high performing monopropellants, then new thruster designs are needed employing new catalyst and thermal materials. Before investing in the difficult task of materials and design development, we wanted to verify that high-performing monopropellant formulations could be safely handled, stored and ignited. This report discusses our efforts to formulate and test HAN-based monopropellants with very high specific impulse (270 seconds to over 280 seconds theoretical Isp). Seven formulations have been prepared, characterized and tested in a small cataTytically ignited rocket thruster. Six of the propellants showed good handling, storage, ignition, and combustion characteristics. Data from the short duration, laboratory-hardware tests is presented in this report. This report also begins to identify concepts and approaches to solving the catalyst/thermal bed material issue. *
Involvement of CYP1B1 in interferon γ‐induced alterations of epithelial barrier integrity

CYP1B1 and CYP1A1 are important extra‐hepatic cytochromes, expressed in the colon and involved in the metabolism of dietary constituents and exogenous compounds. CYP1B1 expression is increased by pro‐inflammatory cytokines, and it has been recently implicated in regulation of blood brain barrier function. We investigated its involvement in the increased permeability of the intestinal epithelial barrier observed in inflammatory conditions.
