Elevated progesterone at initiation of stimulation is associated with a lower ongoing pregnancy rate after IVF using GnRH antagonists

BACKGROUND: The objective of this prospective study was to assess the impact of elevated serum progesterone levels on day 2 of the cycle on pregnancy rates in patients treated by IVF using GnRH antagonists. METHODS: Ovarian stimulation was started on day 2 of the cycle if progesterone levels were normal (normal-P group, n = 390). In the presence of elevated progesterone, initiation of stimulation was postponed for 1 or 2 days (high-P group, n = 20) and was started if repeat progesterone levels returned to normal range (n = 16). Stimulation was performed with recombinant FSH (rFSH) and GnRH antagonist was always started on day 6 of stimulation. RESULTS: A significantly higher exposure to progesterone and a significantly lower exposure to estradiol was present in the high-P as compared with the normal-P group from day 1 to day 8 of stimulation. In addition, a significantly lower ongoing pregnancy rate both per started cycle (5.0% versus 31.8%; P = 0.01) and per embryo transfer (6.3% versus 36.9%; P = 0.01) was present in the high-P compared with the normal-P group, respectively. CONCLUSIONS: The presence of elevated serum progesterone on day 2 of the cycle is associated with a decreased chance of pregnancy in patients treated with rFSH and GnRH antagonists.
Sub-lethal and sub-specific temperature effects are better predictors of mussel distribution than thermal tolerance

: Three classes of mussel, the invasive Mytilus galloprovincialis and 2 genetic lineages of the indigenous Perna perna , show partially overlapping distributions along a large-scale temperature gradient in South Africa. We asked whether their physiological tolerances explain their distributional limits, investigating the effects of acute temperature change on heart rate, oxygen consumption and anaerobic end-product accumulation in air and water in the laboratory. For all 3 classes, heart rate and oxygen consumption were significantly reduced in air and were not correlated with temperature. During immersion, temperature had powerful effects on metabolic rate, but the ranking of heart rates reversed between heat and cold stress. The eastern P. perna lineage had higher heart rates with rising temperatures, while M. galloprovincialis showed higher heart rates during cooling. Despite no difference in upper thermal limits among mussel classes, their Arrhenius activation energies differed significantly, in parallel with their warm to cool distributions in the order P. perna east > P. perna west > M. galloprovincialis . The results indicate that the eastern lineage of P. perna is better adapted to warm temperatures and M. galloprovincialis is better adapted to high shore conditions. Upper thermal limits gave only a crude approximation of the effects of temperature stress. Although the thermal limits of these populations were similar, their overall responses to stress differed markedly, reflecting their distributions and potentially affecting their competitive interactions. We suggest that thermal limits offer poor explanations for species distributions, and highlight the critical importance of both sub-lethal effects and sub-specific differences in physiology.
FATORES DE EROSÃO E SUSCETIBILIDADE MAGNÉTICA EM

The erosion is the degradation of soil with effects on crop productivity and pollution of the environment. To understand the spatial variability of this phenomenon, geostatistical techniques and concepts of soil-landscape can be used to identify landscape compartments with different potential of erosion. The aim of this study was to understand the factors of erosion in landscape compartments and the relations with the magnetic susceptibility (MS) of the soils in a slope in Gilbués, state of Piauí (PI), Brazil. Sampling meshes were set in compartments I and II with 121 points and in compartment III with 99 points spaced every 10 meters. There was significant difference to erodibility (K) and risk of erosion (RE); the spatial variability of MS was lower than the factors of soil erosion. The soil losses (A), the natural erosion potential (NEP), the RE and the MS had spatial relation with the topographic factor, indicating dependence of the erosion with the relief. We concluded that losses of soil, natural erosion potential and risk of erosion have spatial relation with the topographic factor, showing the dependence of the erosion factors with the relief. The soil magnetic susceptibility can be used as an auxiliary variable in the indirect quantification of the erodibility factor and the risk of soil erosion.
the CMS Collaboration (2018). Search for supersymmetry in events with one lepton and multiple jets exploiting the angular correlation between the lepton and the missing transverse momentum in proton–proton collisions at s =13

Results are presented from a search for supersymmetry in events with a single electron or muon and hadronic jets. The data correspond to a sample of proton–proton collisions at √ s = 13 TeV with an integrated luminosity of 35.9fb − 1 , recorded in 2016 by the CMS experiment. A number of exclusive search regions are deﬁned according to the number of jets, the number of b-tagged jets, the scalar sum of the transverse momenta of the jets, and the scalar sum of the missing transverse momentum and the transverse momentum of the lepton. Standard model background events are reduced signiﬁcantly by requiring a large azimuthal angle between the direction of the lepton and of the reconstructed W boson, computed under the hypothesis that all of the missing transverse momentum in the event arises from a neutrino produced in the leptonic decay of the W boson. The numbers of observed events are consistent with the expectations from standard model processes, and the results are used to set lower limits on supersymmetric particle masses in the context of two simpliﬁed models of gluino pair production. In the ﬁrst model, where each gluino decays to a top quark–antiquark pair and a neutralino, gluino masses up to 1.8TeV are excluded at the 95% CL. The second model considers a three-body decay to a light quark– antiquark pair and a chargino, which subsequently decays to a W boson and a neutralino. In this model, gluinos
Storage Effects on Dormancy and Germination of Native Tickseed Species

Fresh seeds of prevariety germplasms of goldenmane tickseed (Coreopsis basalis), florida tickseed (Coreopsis floridana), lanceleaf tickseed (Coreopsis lanceolata), and leavenworth’s tickseed (Coreopsis leavenworthii) were harvested from cultivated plants and stored under dry conditions for 1 to 24 weeks at 15 or 32 C to alleviate dormancy, that is, to promote after-ripening. The relative humidity (RH) was 33% for all species except lanceleaf tickseed (23% RH). Seeds were subsequently stored for 24 weeks in a commercial storage facility at 23% RH/17 to 19 C to determine whether after-ripened seeds could be stored without loss in quality (viability, germination velocity). The only substantial after-ripening occurred with seeds of lanceleaf tickseed, although most after-ripening of lanceleaf tickseed seeds occurred during the 24 weeks of dry storage in the commercial storage facility regardless of storage conditions for the previous 24 weeks. After the 24 weeks in commercial storage, germination of lanceleaf tickseed seeds was 48% to 80%, but germination was only 2% to 15% after 24 weeks of dry storage at 15 or 32 C, respectively. Freshly harvested seeds of the other three species were much more nondormant than seeds of lanceleaf tickseed, but after-ripening effects were still evident because there were increases in germination or germination velocity (an indicator of after-ripening). Maintenance of seed quality was species-dependent. Seed quality of the two upland species, goldenmane tickseed and lanceleaf tickseed, was maintained during the initial 24 weeks of dry storage plus the subsequent 24 weeks in the commercial storage facility. In contrast, viability of seeds of the two wetland species, florida tickseed and leavenworth’s tickseed, declined to varying degrees either during the initial 24 weeks of after-ripening or during storage in the commercial facility. The greatest decline in quality occurred for florida tickseed seeds that were stored for 24 weeks at 32 C and then for 24 weeks in the commercial storage facility.
Reducing Nitrate Accumulation and Fertilizer Use in Lettuce with Modified Intermittent Nutrient Film Technique (NFT) System

Lettuce (Lactuca sativa L.) is a leading greenhouse-grown vegetable. However, nitrate (NO3−) accumulation in leaves remains a major issue. The aims of this research were: (i) to test the modified intermittent Nutrient Film Technique (NFT) in the cultivation of soilless lettuce in which plants are grown on peat blocks in trays and supplied with an intermittent flow of nutrient solution, and (ii) to calibrate the fertilization scheme to increase yield performance, while keeping NO3− concentration under control. Two greenhouse trials were performed between autumn 2013 and spring 2014. Results showed that a 30-day cycle is the optimum duration in terms of fresh biomass yield, both for autumn and spring cultivation. Reducing N fertilization in the last cropping days never affected NO3− concentration in leaves during autumn trial, due to unfavourable growing conditions. Conversely, suspension of fertilization 2 days before harvest had a consistent effect during the spring trial, when NO3− concentration in leaves was highly reduced (from 20 to 36%) without yield penalties. Thus, suspending fertilization 2–4 days before harvesting in intermittent NFT may reduce, on average, NO3− accumulation by 29–58% and the fertilization rate by 7–16%, respectively. Yet, growing conditions are crucial to make this system effective.
On the algebraic characterization of the category of 3-dimensional cobordisms

It is proved in \cite{BP} (arXiv:1108.2717) that the category of relative 3-dimensional cobordisms $\cal Cob^{2+1}$ is equivalent to the universal algebraic category $\overline{\overline{\cal H}}{}^r$ generated by a Hopf algebra object. A different algebraic category $\overline{\cal Alg}$ generated by a Hopf algebra object is defined in \cite{AS} and it conjectured to be equivalent to $\cal Cob^{2+1}$ as well. We prove that there exists a functor $\overline{\cal Alg}\to \overline{\overline{\cal H}}{}^r$, and use it to present an alternative set of axioms for $\overline{\overline{\cal H}}{}^r$.
THE ARAUCARIA FORESTS OF NEW GUINEA AND THEIR REGENERATIVE CAPACITY

Although araucarias feature prominently in the exploratory accounts of Gibbs (1917), Lane-Poole (1925), Archbold & Rand (1935), Archbold, Rand & Brass (1942) and Brass (1956, 1959), the first discussion of their ecological status is that of Womersley (1958). Womersley considered the araucarian stands to be living fossil vegetation which is in process of being swamped by broad-leaved forest, as evidenced by their apparently even-aged nature. He looked on these stands as the outcome of a past catastrophe which removed the broad-leaved competitors, supporting his hypothesis by the observation that logged-over stands usually need to be replaced by even-aged plantations, because natural regeneration is inadequate. Similar ideas were advanced for New Zealand gymnosperms by Robbins (1962) and for Australian and New Caledonian araucarias by Aubreville (1965a, b), who stressed the light-demanding nature of the genus, which limits adequate regeneration to forest margins and open forest types. Aubr6ville also considered seed destruction by animals and aborigines and damage to young trees by fire and frost as additional limiting factors.
Understanding the behavioral equilibrium exchange rate model via its application to the valuation of Chinese renminbi

In this paper, the behavioral equilibrium exchange rate (BEER) model used in a time-series setting is investigated, via its application to the valuation of Chinese renminbi. A classical definition with its generalization is given. The different misalignment results derived from the BEER models are proven to result from the different econometric component choices. It is found that some of the misalignment results are consistent with Chinese economic facts, but some others are not. Finally, four main flaws unavoidable under the BEER model are given and analyzed. JEL classification: F31; F41

On the Hazards of Overemphasizing Numerical Fluctuations in Studies of "Cyclic" Phenomena in Muskrat Populations

The past quarter-century has been one of accelerating scientific interest in fluctuations of wild populations, and this acceleration does not seem to be over. More and more investigators, especially zoologists and wildlife managers, have been concerning themselves with the so-called "cyclic" changes shown by this or that species. The resulting literature has become so voluminous in the English, German, and Scandinavian languages alone, that I doubt that any one person could now truly master it in a lifetime, even if he were competent in all of the fields of science contributing. Its scientifically reputable authors include not only bi1Journal Paper No. J-2392 of the Iowa Agricultural Experiment Station, Ames, Iowa, Project No. 1217.

Pinus halepensis and Eucalyptus camaldulensis grown in Egypt: A comparison between stem and branch properties for pulp and paper making

The utilization of branchwood as lignocellulosic raw material source for paper production may have the potential of solving the problem of the availability of raw material in the pulp and paper industry. This study therefore compared the chemical composition and fiber morphological indices (according to Franklin’s method) of stemwood and branchwood in Eucalyptus camaldulensis and Pinus halepensis trees grown in Egypt. The statistical analysis showed a significant effect of species, wood type (stem and branchwood), and their interaction on the measured chemical constituents and fiber morphological indices at 0.05 significance level. In both genera, the stemwood exhibited a higher percentage of cellulose and hemicellulose and was lower in lignin, total extractives, and ash than those measured in branchwood. Also in both genera, the stemwood was higher in fiber length, Runkel ratio, rigidity coefficient, Muhlsteph ratio, and Luce's shape factor, and lower in basic density and flexibility coefficient than those in branchwood. Based on the chemical analysis and the fiber morphological indices, the stemwood and branchwood of both species were suitable for paper production with various qualities. Moreover, good correlations were found in both stem and branchwood between the basic density and the fiber wall thickness and fiber lumen diameter. ln contrast, there was an independent association between the stemwood basic density and the fiber length, and this relationship in branchwood was positive for both genera.
The Impact of Renewable Energy Generation on the Spot Market Price in Germany: Ex-Post Analysis using Boosting Method

This study combines regression analysis with machine learning analysis to study the merit order effect of renewable energy focusing on German market, the largest market in Europe with high renewable energy penetration. The results show that electricity from wind and solar sources reduced the spot market price by 9.64 €/MWh on average during the period from 2010 to 2017. Wind had a relatively stable impact across the day, ranging from 5.88 €/MWh to 8.04 €/MWh, while the solar energy impact varied greatly across different hours, ranging from 0.24 €/MWh to 11.78 €/MWh and having a stronger impact than wind during peak hours. The results also show characteristics of the interactions between renewable energy and spot market prices, including the slightly diminishing merit order effect of renewable energy at high generation volumes. Finally, a scenario-based analysis illustrates how different proportions of wind and solar energies affect the spot market price.
European Journal of Physical Education and Sport Science-2501-1235

Mental imagery has long been the focus of researchers in sports psychology and motor learning. The purpose of this study is to compare Pet Lep and traditional mental imagery methods in the performance of football goalkeepers. For this purpose, 30 (13 males and 17 females) male and female goalkeepers aged 18 to 30 years were selected as a statistical sample using random cluster sampling. Subjects were divided into three groups and underwent specific exercises. The program of the first group consisted of practical exercises with mental imagery using the Pet Lep method, the second group consisted of practical exercises with mental imagery using the traditional method, and the third group consisted of practical exercises. Then, in the seventh, fourteenth, twenty-first and twentyeighth sessions, all subjects were given a standard ball test and their learning progress was measured. The collected data were then statistically analyzed by one-factor analysis of variance test and Tukey test. Research findings showed that there is a significant difference in the level of learning the ball skill between Pet Lep mental imagery group and traditional illustration group and traditional illustration group and control group in all three stages of training. Also, a significant difference was observed in the retention of ball skills after one week of training between the Pet Lep mental imaging group and the traditional and control mental imaging groups. Finally, it is suggested that sports coaches and trainers use the Pet Lep imaging method in appropriate situations.
An Empirical Study of National vs. Local Pricing under Multimarket Competition

Geographic price discrimination is generally considered beneficial to firm profitability. Firms can extract higher rents by varying prices across markets to match consumers’ preferences. This paper empirically demonstrates, however, that a firm may instead prefer a national pricing policy that fixes prices across geographic markets, foregoing the opportunity to customize prices. Under appropriate conditions, a national pricing policy helps avoid intense local competition due to targeted prices. I examine the choice of national versus local pricing under multimarket retail chain competition using extensive data from the digital camera market. I estimate a highly flexible model of aggregate demand that incorporates additional micro purchase moments and semi-parametric heterogeneity. Counterfactual analyses show that the major retail firms should employ a national pricing policy to maximize profits. Fixing prices across markets allows the retailers to soften otherwise intense local competition by subsidizing competitive markets with profit from less competitive markets. Additional results explore how market factors could affect the pricing policy decision and assist retail managers in choosing their geographic pricing policy. ∗Graduate School of Business, Columbia University.

Contract Management Implementation : a roadmap built on critical success factors

This thesis investigates the critical success factors of the implementation of contract management. A lack of adequate contract management is one of the main reasons for outsourcing to not produce the expected results. The main internal reason for inadequate contract management is its improper implementation. This thesis therefore aims to find those factors that are of crucial importance in ensuring a successful implementation of contract management and ultimately build a roadmap upon these factors. This study will find those critical success factors by investigating the implementation of specifically contract management; the impact of change management theory on the implementation process; and the integration of contract management in the organisational structure. The base of this research consists of two World Café discussions, organized by Het NIC. This research collected two different sets of data. The first set of data was collected via a questionnaire, which was distributed before the start of the World Café sessions. In order to obtain participant related information, this questionnaire consisted of questions regarding their ‘age’, ‘gender’, ‘education’ and ‘work-life’. This participant related data was collected, in order to be able to test whether differences in outcomes between the two World Café sessions, could be attributed to the differences in research population between
