How intercourse frequency is affected by relationship length, relationship quality, and sexual strategies using couple data.

The frequency of sexual intercourse within couples is associated with a variety of factors, such as relationship length, sexual and relationship satisfaction, and perceived quality of the relationship. Love, as a commitment device, might reduce interest in extra-pair sex. One can therefore expect a negative association between measures of passion and sociosexual desire. Further, we wish to explore the effects of decoupling love and sex as measured by sociosexual attitudes on sexual frequency; as there might be a greater willingness to compromise on frequency of sex if sex is less related to expression of emotions and relational quality. We examined how men and women’s sociosexuality, relationship length and various dimensions of relationship quality impact couples’ intercourse frequency. Structural Equation Modelling analyses were performed on data from 92 romantically involved, heterosexual couples recruited at a Norwegian university. Participants’ age ranged from 19 to 30 years. The current relationship length ranged from one month to nine years (M = 21 months). Intercourse frequency decreased with increased length of relationship. Both men and women’s ratings of relationship passion were strongly associated with frequency of having sex, but negatively associated with desire for extra-pair sex. Intercourse was more frequent in couples where women reported less restricted attitudes, while men’s level of sociosexuality had no effect on intercourse frequency in any of the models. These novel findings suggest that while men in general might desire sex more, in this sample from a highly egalitarian nation, men might be compromising more than women do.

We examined how relationship length, relationship quality and short-term sexual orientation influenced frequency of sexual intercourse in 92 couples. How often couples have intercourse was predicted by the woman’s short-term sexual orientation, and particularly her attitudes towards casual sex. We suggest that in a highly egalitarian country, men more than women compromise how often they have sex with their partner. INTERCOURSE FREQUENCY 3

Transport and Retention of Manure‐Borne Coliforms in Soil

Manure is a source of several bacterial pathogens that can potentially contribute to surface and groundwater contamination. Results from most bacterial transport studies in soils are only partially applicable to manure‐borne bacteria because microorganisms are released along with manure particulates as manure dissolves. The objective of this study was to compare transport of chloride ion, Escherichia coli (E. coli) and manure colloids in undisturbed soil columns with a well‐developed structure. Breakthrough column experiments were conducted with undisturbed, 20‐cm long Tyler soil columns from the A horizon. A pulse of 4% filtered bovine manure solution with E. coli and KCl was passed through the columns. Escherichia coli concentrations, chloride content, and turbidity were measured in influent and in effluent. Columns were cut into 2‐cm layers after the experiment to measure: (i) viable bacterial concentrations in pore solution and attached to soil; (ii) bulk density; (iii) water content. Companion batch experiments were performed to measure attachment of E. coli to soil in the presence of various amounts of manure. Escherichia coli attachment to soil decreased with increased manure content due to increased competition for attachment sites. Flow velocity affected E. coli transport and attachment to soil; there was relatively more attachment at slower flow velocity than at higher flow velocity. Escherichia coli attachment to soil was 18, 5, and 9% at flow velocities of 2.3, 8.4, and 9.3 cm d−1, respectively. Spatial variability in soil structure may result in large variations of pore water velocity and consequent differences in transport of manure particulates and bacteria under ponded infiltration.
Effects of snow ratio on annual runoff within the Budyko framework

A warmer climate may lead to less precipitation falling as snow in cold seasons. Such a switch in the state of precipitation not only alters temporal distribution of intra-annual runoff but also tends to yield less total annual runoff. Long-term water balance for 282 catchments across China is investigated, showing that a decreasing snow ratio reduces annual runoff for a given total precipitation. Within the Budyko framework, we develop an equation to quantify the relationship between snow ratio and annual runoff from a water–energy balance viewpoint. Based on the proposed equation, attribution of runoff change during the past several decades and possible runoff change induced by projected snow ratio change using climate experiment outputs archived in the Coupled Model Intercomparison Project Phase 5 (CMIP5) are analyzed. Results indicate that annual runoff in northwestern mountainous and northern high-latitude areas are sensitive to snow ratio change. The proposed model is applicable to other catchments easily and quantitatively for analyzing the effects of possible change in snow ratio on available water resources and evaluating the vulnerability of catchments to climate change.
An Innovative Cost-Benefit Model for Analyzing Solution Architectures Considering Uncertainty

In the dynamic environment nowadays, companies require continuously to implement and improve their technology solutions to respond to new technology tendencies, business requirements, and enterprise architecture initiatives. This transformation is supported by solution architectures, which contain solution components that are implemented to respond to company’s requirements. As a consequence, the ability to analyze solution architectures financially becomes significantly essential to determine their costs, benefits, profitability, and the impact of the unpredictable events that can derive positive or negative consequences in technology investments. However, since most current financial models address overall IT investments, it is difficult to calculate the detailed and precise financial indicators required for solution architectures and their components. Consequently, financial variables can be omitted, and financial indicators can be limited and insufficient to analyze advantages, disadvantages, and risks associated with solution architectures and their components. With this in mind, our study presents an innovative cost-benefit model specifically for solution architectures. To define, design and evaluate our model, we adopted the Design Science Research paradigm. As a result of the model’s evaluation, we determined that our model calculates specific indicators related to alternatives and components which can reduce the risk omitting of variables while increasing flexibility for comparing alternatives and provision of support for technology investment decisions.
Comparison of isokinetic strengthening with functional strengthening of lower limb and their effect on gait in hemiparesis due to stroke.

Background: A large number of survivors of stroke present with various disabilities including motor deficits characterized by weakness (hemiparesis) on one side of the body opposite to the site of lesion. Muscle weakness in the affected lower limb of stroke patients is a major factor inhibiting gait ability which is the most frequently stated goal by persons with stroke. Progressive resistance strength training has been found to strengthen paretic muscles after stroke including isokinetic strengthening and functional strengthening. Purpose: The present study intended to examine whether one of the two types of lower limb strengthening (isokinetic strengthening and functional strengthening) is more beneficial in improving peak torque, six-minute walk test and step length in post stroke hemiparetic persons. Method: A total 30 number of subjects were randomly selected and assigned to either of the two groups after meeting the inclusion and exclusion criteria. All participants underwent an initial baseline assessment. Both groups received conventional physiotherapy. Group 1 in addition, received isokinetic strengthening, whereas group 2 in addition, received functional strengthening for a period of 6 weeks, 3 days/ week. All participants received a follow up assessment after completion of 6 weeks. Results: The overall results of the study suggest that after 6 weeks of intervention both the groups (isokinetic strengthening and functional strengthening) improved significantly in peak torque of hip flexor, hip extensor, knee flexor, knee extensor, ankle dorsiflexor, plantarflexor, six-minute walk test, step length affected and step length non-affected. Isokinetic strengthening group showed significantly better improvement in peak torque of hip flexor, hip extensor, knee flexor, knee extensor and six-minute walk test. Conclusion: Isokinetic strengthening of lower limb is more effective than functional strengthening in improving peak torque of hip-knee flexor and extensor muscles and six-minute walk test. However, no significant difference was noted in peak torque of ankle muscles and step length of both affected and non-affected side in post stroke hemiparetic persons.

Improving the Sound Recording Quality of Wireless Sensors Using Automatic Gain Control Methods

When performing speech recording it is desirable to have the speech signal in as a high quality as possible. In everyday recording conditions one of the most important aspects of sound quality is to have a uniform volume level, because it is very hard to understand (and to automatically recognize) an utterance with a volume level that varies considerably. Of course this uniform volume level should also be an average one, avoiding either too loud or too quiet recordings. To overcome this problem usually an approach called Automatic Gain Control is used, which is an adaptive method for controlling microphone sensitivity (gain). Wireless sensors are recent, low-powered devices, which are ideal for recording and transmitting observations such as speech, thus they are a good area for applying automatic gain control. Due to their low power consumption, however, only very simple solutions can be implemented. Here we will present a general gain control algorithm, then introduce two variations that we test in a situation which simulates the actual use. We perform evaluations by using two types of measurement: the first one compares local volume levels to recordings made under ideal conditions, while in the second we measure the understandability of the recordings made by applying standard speech recognition techniques. Our results in both cases confirm that it is indeed an area where automatic gain control can be applied, and that both our algorithms perform well in practice.
PR ] 9 A ug 2 01 8 Conjugate Duality on Wasserstein Spaces with Applications in Partially Observable Markov Decision Processes

By exploiting the relationship between the Wasserstein-1 space and the space of Lipschitz functions, we provide a dual representation of Fenchel-Moreau type for proper convex functionals on the Wasserstein-1 space. We apply the aforementioned duality to the field of Partially observable Markov decision processes (POMDPs), and derive an approximation to the value function of a given POMDP by iterating level sets. This extends the method used in Smallwood and Sondik (1973) for finite state spaces to the case were the state space is a Polish metric space.
Exploring the multihumped fission barrier of 238U via sub-barrier photofission

The photofission cross-section of 238U was measured at sub-barrier energies as a function of the gamma-ray energy using, for the first time, a monochromatic, high-brilliance, Compton-backscattered gamma-ray beam. The experiment was performed at the High Intensity gamma-ray Source (HIgS) facility at beam energies between E=4.7 MeV and 6.0 MeV and with ~3% energy resolution. Indications of transmission resonances have been observed at gamma-ray beam energies of E=5.1 MeV and 5.6 MeV with moderate amplitudes. The triple-humped fission barrier parameters of 238U have been determined by fitting EMPIRE-3.1 nuclear reaction code calculations to the experimental photofission cross section.
Vacation Home Rental Concept and Its Connection to Climate Change—A Literature Review

Gone are the days when tourists had to rely solely on hotels. The new age tourists’ accommodation is simply known as vacation home rentals. Companies like Airbnb seem to be taking leaps in the tourism sector with the rapid propagation of their vacation home rental concepts; making hotels fear losing their position on the market. Moreover, with rising issues on climate change, it has become worth understanding how vacation home rental can aid. As such, this study has attempted to understand how vacation home rental companies function, their possible threat to hotels and their contribution to mitigate and adapt to climate changes. This study adopted a qualitative research methodology and used the integrative literature review approach. Climate change is a global phenomenon impelling people to think and act differently so as to have a better future. So, are vacation home rental concepts a boon for the planet and its living entities while being a curse for hotels?
Can the Gains from International Diversification Be Achieved without Trading Abroad

We examine whether portfolios of domestically traded securities can mimic foreign indices so that investment in assets that trade only abroad is not necessary to exhaust the gains from international diversification. We use monthly data from 1976 to 1993 for seven developed and nine emerging markets. Return correlations, mean-variance spanning, and Sharpe ratio test results provide strong evidence that gains beyond those attainable through home-made diversification have become statistically and economically insignificant. Finally, we show that the incremental gains from international diversification beyond home-made diversification portfolios have diminished over time in a way consistent with changes in investment barriers.

ENSO flavors in a tree-ring δ 18 O record of Tectona grandis from Indonesia

Abstract. Indonesia's climate is dominated by the equatorial monsoon system, and has been linked to El Nino-Southern Oscillation (ENSO) events that often result in extensive droughts and floods over the Indonesian archipelago. In this study we investigate ENSO-related signals in a tree-ring δ18O record (1900–2007) of Javanese teak. Our results reveal a clear influence of Warm Pool (central Pacific) El Nino events on Javanese tree-ring δ18O, and no clear signal of Cold Tongue (eastern Pacific) El Nino events. These results are consistent with the distinct impacts of the two ENSO flavors on Javanese precipitation, and illustrate the importance of considering ENSO flavors when interpreting palaeoclimate proxy records in the tropics, as well as the potential of palaeoclimate proxy records from appropriately selected tropical regions for reconstructing past variability of. ENSO flavors.
Inferring internal properties of Earth's core dynamics and their evolution from surface observations and a numerical geodynamo model

Over the past decades, direct three-dimensional numerical modelling has been successfully used to reproduce the main features of the geodynamo. Here we report on efforts to solve the associated inverse problem, aiming at inferring the underlying properties of the system from the sole knowledge of surface observations and the first principle dynamical equations describing the convective dynamo. To this end we rely on twin experiments. A reference model time sequence is first produced and used to generate synthetic data, restricted here to the large-scale component of the magnetic field and its rate of change at the outer boundary. Starting from a different initial condition, a second sequence is next run and attempts are made to recover the internal magnetic, velocity and buoyancy anomaly fields from the sparse surficial data. In order to reduce the vast underdetermination of this problem, we use stochastic inversion, a linear estimation method determining the most likely internal state compatible with the observations and some prior knowledge, and we also implement a sequential evolution algorithm in order to invert time-dependent surface observations. The prior is the multivariate statistics of the numerical model, which are directly computed from a large number of snapshots stored during a preliminary direct run. The statistics display strong correlation between different harmonic degrees of the surface observations and internal fields, provided they share the same harmonic order, a natural consequence of the linear coupling of the governing dynamical equations and of the leading influence of the Coriolis force. Synthetic experiments performed with a weakly nonlinear model yield an excellent quantitative retrieval of the internal structure. In contrast, the use of a strongly nonlinear (and more realistic) model results in less accurate static estimations, which in turn fail to constrain the unobserved small scales in the time integration of the evolution scheme. Evaluating the quality of forecasts of the system evolution against the reference solution, we show that our scheme can improve predictions based on linear extrapolations on forecast horizons shorter than the system e -folding time. Still, in the perspective of forthcoming data assimilation activities, our study underlines the need of advanced estimation techniques able to cope with the moderate to strong nonlinearities present in the geodynamo.

This work exploits the high-affinity of recombinant antibodies and low background electrochemiluminescence (ECL) for cardiac-biomarker detection. The developed assay is capable of fg mL−1 detection limits as well as the detection of C-Reactive Protein (CRP) over a clinically relevant range. The assay demonstrated robust reproducibility, selectivity and stability while also highlighting a novel platform for detection of cardiac biomarkers at low concentrations.
Ricci curvature and isometric actions with scaling nonvanishing property

In the study manifolds of Ricci curvature bounded below, a stumbling obstruction is the lack of links between large-scale geometry and small-scale geometry at a fixed reference point. There have been few links (volume, dimension) when the unit ball at the point is not collapsed, that is, $\mathrm{vol}(B_1(p))\ge v>0$. In this paper, we conjecture a new link in terms of isometries: if the maximal displacement of an isometry $f$ on $B_1(p)$ is at least $\delta>0$, then the maximal displacement of $f$ on the rescaled unit ball $r^{-1}B_r(p)$ is at least $\Phi(\delta,n,v)>0$ for all $r\in(0,1)$. We call this scaling $\Phi$-nonvanishing property at $p$. We study the equivariant Gromov-Hausdorff convergence of a sequence of Riemannian universal covers with abelian $\pi_1(M_i,p_i)$-actions $(\widetilde{M}_i,\tilde{p}_i,\pi_1(M_i,p_i))\overset{GH}\longrightarrow(\widetilde{X},\tilde{p},G)$, where $\pi_1(M_i,p_i)$-action is scaling $\Phi$-nonvanishing at $\tilde{p_i}$. We establish a dimension monotonicity on the limit group associated to any rescaling sequence. As one of the applications, we prove that for an open manifold $M$ of non-negative Ricci curvature, if the universal cover $\widetilde{M}$ has Euclidean volume growth and $\pi_1(M,p)$-action on $R^{-1}\widetilde{M}$ is scaling $\Phi$-nonvanishing at $\tilde{p}$ for all $R$ large, then $\pi_1(M)$ is finitely generated.
