How Review Sentiment and Readability Affect Online Peer Evaluation Votes? – An Examination Combining Reviewer’s Social Identity and Social network

To encourage users’ engagement and crowdsource quality control, many online communities provide users with peer evaluation votes. By using a total number of 17,178 online hotel reviews from Yelp, this study explored the factors influencing hotel review peer evaluations. The empirical results show that (1) multiple motivations exist for peer evaluations of online reviews; (2) except for reviews’ post date, length, and hotel popularity, readability of hotel review has positive influences on evaluation votes; (3) review sentiment has stronger influences on evaluation votes than other factors; (4) the effects of hotel review sentiment and readability on peer evaluation votes are positively moderated by reviewer’s social identity and social network.
Sexual dimorphism in bite force in the grey mouse lemur

Sexual dimorphism is thought to be the result of sexual selection, food competition and/or niche differentiation, or simply the result of differential growth between the sexes. Despite the fact that sexual dimorphism is common among primates, lemurs are thought to be largely monomorphic. Yet, females of the species Microcebus are known to be larger than males. Here, we investigate if dimorphism in head dimensions is present in a colony of captive grey mouse lemurs Microcebus murinus. Moreover, we test whether any observed shape dimorphism is associated with differences in bite force between the sexes. Our results show that male and female grey mouse lemurs are indeed sexually dimorphic in head dimensions, with females having taller and wider heads than males. Moreover, we confirm previous observations that females are heavier than males. Bite force was principally determined by head dimensions and age in our dataset, and differed between sexes, with females biting harder than males. These data suggest a potential role for niche dimorphism in driving the observed shape and performance dimorphism as female reproductive output may depend upon the ability of animals to obtain resources that are difficult to ingest.
Motion events in Afrikaans: their expression by adult speakers and by children with and without language impairment

Motion events occur frequently in everyday life as people and objects constantly change their relative location to one another. Although children's descriptions of motion events resemble those of adults in their own language group from very early on (Choi and Bowermann 1991), there is increasing evidence for subtle differences as well. Young children speaking different languages seem to have some difficulty in expressing two types of spatial information in the same conceptual frame (e.g. Ochsenbauer and Hickmann 2010). In English and other satellite-framed languages such as German and Afrikaans, this task involves using a complex particle verb construction in which a directional particle (e.g. out) combines with a prepositional phrase carrying further information about the source or goal of movement (e.g. some bees came out of the tree) (Berman and Slobin 1994:161). Little is known about the development of this type of structure in satellite-framed languages such as Afrikaans. This paper examined whether (i) there are developmental differences between adults and 6-year-old Afrikaans-speaking children in the production of preposition+verb particle structures, and whether (ii) children with language impairment produce these structures in a different way than typically developing children. Target elements were preposition+verb particle structures with the particles af 'down', in 'in', uit 'out' and op 'up'. The performance of ten adults was compared to that of 30 typically developing and three language-impaired 6-year-olds. Half of the participants in the adult and typically developing groups were speakers of Mainstream Afrikaans (MA), and half were speakers of Cape Afrikaans (CA), a non-mainstream dialect. Distinct developmental differences that could not be attributed to dialectal variation, were found between 6-year-olds and adults. Children with language impairment showed less variation in their responses than their typically developing peers. Possible explanations for the findings are discussed.
THERMODYNAMIC MODELING OF VAPOR-LIQUID EQUILIBRIUM FOR PETROLEUM FLUIDS

The phase behavior prediction is essential for the development and optimization of the hydrocarbon production in petroleum engineering applications. Well succeed projects in this field, such as management of a reservoir, multiphase flow analysis in production systems, and petroleum primary processing, depend on the correct prediction of phase behavior and the estimation of thermodynamic properties, like phase composition and compressibility factor. In this way, the present work purpose was to develop a computational tool that performs isothermal flash calculations for oil and gas multicomponent mixtures with enough precision for both project and operation. The computer program was developed in Visual Basic Application (VBA). The Peng-Robinson equation of state was used to model the vapor-liquid equilibrium. Newton-Raphson method was applied to obtain both the convergence of the Rachford-Rice equation and the cubic equation roots. The root for each phase was determined by the Gibbs energy minimization. There is a quantitative agreement between the results computed and the results provided by the commercial simulator HYSYS (AspenTech) over industrially relevant ranges of compositions, pressures and temperatures. Furthermore, the answers obtained are within precision which apply to compositional modeling for petroleum fluids. The composition and compressibility factor simulations for petroleum fluid were performed using real field conditions. The results found were investigated from the thermodynamic viewpoint and were consistent with both practice and theory.
How to Determine the Ideal Increased Progesterone Levels Cutoff During Fresh In Vitro Fertilization Cycles: Is it Time to Move Forward-A Short Commentary

That increased progesterone(P) that is present on the day of human chorionic gonadotropin (HCG)trigger has an effect on the probable chances of a pregnancy resulting following a fresh embryo transfer has been a point that can be debated over the last 25 years [1-3]. A meta-analysis conducted by Venetis et al in 2013, confirmed the negative effect of progesterone on pregnancy following an ET [3]. They Further confirmed that by using proper analytical approaches one can find this correlation [4]. How this effect is brought about is by changing endometrial receptivity, an approach tested both by basic along with clinical research. Most importantly this support comes from cycles in which increased P do not affect if the embryos are frozen and transferred in subsequent cycle of frozen-thawed embryos [3]. Hence a proposal of freeze all/ freeze only policy was suggested as an answer to manage increased P found by the end of follicular phase.
Skill-Biased Technological Change and the Business Cycle

Abstract Over the past two decades, technological progress in the United States has been biased toward skilled labor. What does this imply for business cycles? We construct a quarterly skill premium from the CPS and use it to identify skill-biased technology shocks in a VAR with long-run zero and sign restrictions. Hours fall in response to skill-biased technology shocks, indicating that part of the technology-induced fall in hours is due to a compositional shift in labor demand. Investment-specific technology shocks reduce the skill premium, indicating that capital and skill are not complementary in aggregate production.
Enhanced particle tracking algorithm based on a modified expectation maximization algorithm

An enhanced particle tracking algorithm is developed based on a modified expectation maximization algorithm. Particle tracking results using this method for a series of nine synthetic vortical test images are compared to results obtained using the algorithms of Baek & Lee [1] and Labonte [2]. The test cases utilized particle drop out, varying vortex sizes and shapes and other parameters to evaluate the algorithms. The appreciable improvement in the accuracy of EPTA tracking results for the test cases presented here shows the benefits of explicitly incorporating a vector field representation that is flexible yet regularized and serves as a model to both guide and constrain the process of determining particle correspondence. In particular, it is shown how two B-spline surfaces that are regularized using either a thin plate spline (TPS) or velocity-shear-dilation (VSD) model can accommodate flow gradients while attempting to maintain a degree of smoothness in the displacement field during the determination of particle-to-particle correspondence. Nine synthetic test cases are used to benchmark the utility of the EPTA in comparison with the algorithms of Baek & Lee [1] and Labonte [2]; however, it is important to note that this comparative analysis is not meant to statistically quantify the amount by which one algorithm is ‘better’ than another. Providing a conclusive comparison between the many existing PTV algorithms over a range of flow conditions has yet to appear in the literature and should be the subject of future work. With this in mind, it should also be noted that accomplishing such a task will not be a simple matter because there is not unified agreement about the important aspects that should make up such a comparison.
The theory of infinitely divisible matrices and kernels

when he showed recently that the Green's function for Laplace's equation is, under certain conditions, an infinitely divisible kernel. In this paper we shall develop a general theory of infinitely divisible kernels and indicate briefly a few of its applications. It is convenient to begin by examining the discrete analogues of the infinitely divisible kernels, i.e., infinitely divisible matrices. In ? 1 we characterize this class of matrices and show that the occurrence of zeros among their entries is subject to a certain condition which is most easily stated in the language of graph theory. We then use the matrical theory to obtain corresponding results for continuous infinitely divisible kernels, and we develop the technical tools for dealing with these kernels which are needed later in the applications. We shall use Rm and Cm to denote m-dimensional real and complex space,
Crustal subsidence observed by GRACE after the 2013 Okhotsk deep‐focus earthquake

Coseismic gravity changes stem from (1) vertical deformation of layer boundaries with density contrast (i.e., surface and Moho) and (2) density changes of rocks at depth. They have been observed in earthquakes with Mw exceeding ~8.5 by Gravity Recovery and Climate Experiment (GRACE) satellites, but those of M8 class earthquakes have never been detected clearly. Here we report coseismic gravity change of the 24 May 2013 Okhotsk deep earthquake (Mw8.3), smaller than the detection threshold. In shallow thrust faulting, factor (2) is dominant, while factor (1) remains secondary due to poor spatial resolution of GRACE. In the 2013 Okhotsk earthquake, however, factor (2) is insignificant because they occur at depth exceeding 600 km. On the other hand, factor (1) becomes dominant because the centers of uplift and subsidence are well separated and GRACE can resolve them. This enables GRACE to map vertical ground movements of deep earthquakes over both land and ocean.
Numerical Optimization of Plasmonic Biosensors

Since the engineering control of the deposition of nanometric gold plates on substrates the Surface Plasmon Resonance (SPR) based sensor has become one of the most successful label-free and commercially developed optical sensor, with applications to biology (Hoaa et al., 2007; Kolomenskii et al., 1997; Kretschman & Raether, 1968; Lecaruyer et al., 2006). This technique is currently employed in biomolecular engineering, drug design, monoclonal antibody characterization, virus-protein interaction, environmental pollutants detection, among other interesting problems. The basic principle of such transducer is the measurement of the sudden absorbtion of light by the thin metallic layer, under particular illumination conditions (p-polarization) and a specific angle of incidence of the illumination (Barchiesi, Kremer, Mai & Grosges, 2008; Barchiesi, Macias, Belmar-Letellier, Van Labeke, Lamy de la Chapelle, Toury, Kremer, Moreau & Grosges, 2008; Kretschman & Raether, 1968), leading to a highly sensitive device (Kolomenskii et al., 1997; Lecaruyer et al., 2006). The conditions of such absorption are linked to the plasmon resonance in metallic structure, and therefore a tiny change of the optical properties of medium above the gold plate, produces an angular shift of this absorption, due to the detuning of the resonance. The sensing principle relies therefore on the shift of the plasmonic resonance caused by the surrounding dielectric environmental change in a binding event. The Plasmonic biosensors use the property of resonance between an illumination and the metallic part of the sensor. This resonance is used to increase the sensitivity of the biosensor and the threshold of detection. Actually, a given set of parameters of the biosensor can lead to a maximum of the absorption of the incoming light. A slight change of its immediate environment (presence/Absence of biomoecules to be detected) produces a strong change of the detected light due to the detuning of the resonance. This property is also used in cancer therapy or imaging, throughmetallic nanoparticles or nanoshells (Grosges, Barchiesi, Toury& Grehan, 2008). The design of specific shapes for nanoparticles can help to tune the resonance for specific applications (Billot et al., 2006). In the case of planar SPR (Surface Plasmon Resonance) biosensors, the reflected intensity vanishes for a specific angle of incidence. The illumination is almost totally coupled in the metal layer. A tiny change of the optical index of the upper medium, due to the presence of biomolecules, produces a measurable shift of this minimum. Therefore, to improve the efficiency of the sensor, the material and geometrical characteristics of the materials involved in the biosensor must be adjusted correctly. Surprisingly, the optimization of such structures has rarely been addressed (Ekgasit et al., 2005; Kolomenskii et al., 1997; Lecaruyer et al., 5
Melting processes and fluid and sediment transport rates along the Alaska-Aleutian arc from an integrated U-Th-Ra-Be isotope study

[1] A comprehensive data set for young lavas erupted along the Alaska-Aleutian arc is used to examine how fluid and sediment transport rates and melting processes vary in response to systematic changes in subduction rate and dip along the arc and across the ocean-continent boundary. Positive correlations between convergence rate, volcano volume, and 238U excesses suggest that magmatic output is closely linked to the size of the fluid flux which occurred <10 kyr prior to eruption. Sediment-sensitive tracers like Th/Nb, Ce/Ce*, and 10Be/9Be also increase with convergence rate. However, the inferred 10Be/9Be ratio of this component is low relative to that in the incoming sediments, and this could reflect either sediment removal by accretion or storage in the mantle wedge for ∼0.5–1 Myr. Th/Nb and Th/Nd ratios exceed those expected from bulk sediment addition in the center of the arc suggesting that the enhanced sediment signal reflects transfer in a partial melt phase, whereas partial melts from the subducted oceanic crust appear to be restricted to the western tear in the Pacific plate. Therefore the thermal structure at the slab-wedge interface in the center of the arc must lie close to, and possibly between, the sediment and basalt solidii and is thus constrained to be in the region of 670–740°C at 3 GPa. Elevated (230Th/232Th) ratios, the occurrence of 230Th excesses and only modest 226Ra excesses in many of the lavas are modeled as the products of dynamic melting effects superimposed upon a fluid-fluxed mantle wedge. The transition from oceanic to continental lithosphere seems to play an important role in determining the relative effects of fluid addition and partial melting upon U-Th disequilibria. We infer that the change from fast and steep plate subduction in the Aleutians to shallow and slow subduction, coupled with increasing lithospheric lid thickness, in Alaska together control slab and wedge temperatures and the rate of matrix flow through the melting region.
Inclusion of potential vorticity uncertainties into a hydrometeorological forecasting chain: application to a medium size basin of Mediterranean Spain

Abstract. The improvement of the short- and mid-range numerical runoff forecasts over the flood-prone Spanish Mediterranean area is a challenging issue. This work analyses four intense precipitation events which produced floods of different magnitude over the Llobregat river basin, a medium size catchment located in Catalonia, north-eastern Spain. One of them was a devasting flash flood – known as the "Montserrat" event – which produced 5 fatalities and material losses estimated at about 65 million euros. The characterization of the Llobregat basin's hydrological response to these floods is first assessed by using rain-gauge data and the Hydrologic Engineering Center's Hydrological Modeling System (HEC-HMS) runoff model. In second place, the non-hydrostatic fifth-generation Pennsylvania State University/NCAR mesoscale model (MM5) is nested within the ECMWF large-scale forecast fields in a set of 54 h period simulations to provide quantitative precipitation forecasts (QPFs) for each hydrometeorological episode. The hydrological model is forced with these QPFs to evaluate the reliability of the resulting discharge forecasts, while an ensemble prediction system (EPS) based on perturbed atmospheric initial and boundary conditions has been designed to test the value of a probabilistic strategy versus the previous deterministic approach. Specifically, a Potential Vorticity (PV) Inversion technique has been used to perturb the MM5 model initial and boundary states (i.e. ECMWF forecast fields). For that purpose, a PV error climatology has been previously derived in order to introduce realistic PV perturbations in the EPS. Results show the benefits of using a probabilistic approach in those cases where the deterministic QPF presents significant deficiencies over the Llobregat river basin in terms of the rainfall amounts, timing and localization. These deficiences in precipitation fields have a major impact on flood forecasts. Our ensemble strategy has been found useful to reduce the biases at different hydrometric sections along the watershed. Therefore, in an operational context, the devised methodology could be useful to expand the lead times associated with the prediction of similar future floods, helping to alleviate their possible hazardous consequences.
Efficient Convex Completion of Coupled Tensors using Coupled Nuclear Norms

Coupled norms have emerged as a convex method to solve coupled tensor completion. A limitation with coupled norms is that they only induce low-rankness using the multilinear rank of coupled tensors. In this paper, we introduce a new set of coupled norms known as coupled nuclear norms by constraining the CP rank of coupled tensors. We propose new coupled completion models using the coupled nuclear norms as regularizers, which can be optimized using computationally efficient optimization methods. We derive excess risk bounds for proposed coupled completion models and show that proposed norms lead to better performance. Through simulation and real-data experiments, we demonstrate that proposed norms achieve better performance for coupled completion compared to existing coupled norms.

Discovering intermediate-mass black hole lenses through gravitational wave lensing

Intermediate-mass black holes are the missing link that connects supermassive and stellar-mass black holes and are key to understanding galaxy evolution. Gravitational waves, like photons, can be lensed by these objects. In the diffraction limit a gravitational wave can self interfere when bent by a mass of Schwarzschild radius comparable to its wavelength, modifying the observed waveform. The required point mass scale is $\sim 100-1000~\rm M_\odot$ for significant wave effect to occur for compact binaries in the LIGO band, corresponding to intermediate-mass black hole deflectors. We perform a mock data study using lensed gravitational waves to investigate detectability of these intermediate-mass black hole deflectors in the LIGO-Virgo detector network. In particular, we simulate gravitational waves with different source distributions lensed by an astrophysical population of intermediate-mass black holes and use standard LIGO tools to infer the properties of these lenses. We show that one can discover intermediate-mass black holes through their lensing effects on gravitational waves in the LIGO-Virgo detector network. Moreover, we demonstrate that one can detect intermediate-mass black holes at $\rm 98 \%$ confidence level in $\sim \rm 20 \%$ of the lensed cases, subject to the astrophysical lens population.
TOC implementation in a medium-scale manufacturing system with diverse product rooting

ABSTRACT Although the Theory of Constraints (TOC) is a widely known management concept, it warrants further research, particularly in terms of its application. The study investigates TOC implementation in a medium-scale manufacturing system with diverse products. The instrumental case study methodology is employed in this study, and the conceptual studies assess the case. The study helps to elucidate the methodology of TOC implementation in a manufacturing system. Instead of the five-step sequential approach that exploits constraints one after another, the cycles of system productivity target points are proposed, where each improvement cycle simultaneously considers several constraints. The proposed methodology is visualised, several implications and suggestions for constraint identification are provided, and a new method of bottleneck identification is elaborated in this study.
