description: We advance theoretical methods for studying propagation effects in the Fast Radio Burst (FRB) spectra. We derive their autocorrelation function in the model with diffractive lensing and strong Kolmogorov-type scintillations and analytically obtain the spectra lensed on different plasma density profiles. With these tools, we reanalyze the highest frequency 4-8 GHz data of Gajjar et al. (2018) for the repeating FRB 20121102A (FRB 121102). In the data we discover, first, a remarkable spectral structure of almost equidistant peaks separated by $95\pm 16$ MHz. We suggest that it can originate from diffractive lensing of the FRB signals on a compact gravitating object of mass $10^{-4}\, M_\odot$ or on a plasma underdensity near the source. Second, the spectra include erratic interstellar, presumably Milky Way scintillations. We extract their decorrelation bandwidth $3.3\pm 0.6$ MHz at reference frequency 6 GHz. The third feature is a GHz-scale pattern which, as we find, linearly drifts with time and presumably represents a wide-band propagation effect, e.g. GHz-scale scintillations. Fourth, many spectra are dominated by a narrow peak at 7.1 GHz. We suggest that it can be caused by a propagation through a plasma lens, e.g., in the host galaxy. Fifth, separating the propagation effects, we give strong arguments that the intrinsic progenitor spectrum has narrow GHz bandwidth and variable central frequency. This confirms expectations from the previous observations. We discuss alternative interpretations of the above spectral features.

description: Quality grade, yield grade, and other feedlot performance factors explain much of the variation in profit under grid pricing. Thus, feedlot owners can change profits by adjusting time on feed to influence these performance factors. This research uses growth models, logistic regression, and an optimization process to determine how the optimal number of days on feed changes under different grid pricing structures. It was found that large quality or small yield discounts increases the optimal number of days on feed and small quality or large yield discounts result in fewer days on feed. Losses associated with a grid having large quality discounts are minimized as cattle fed for more days are able to obtain Choice premiums despite the discounts for more Yield Grade 4 and 5 carcasses. Given small quality discounts, cattle fed for a shorter length of time can obtain the Yield Grade 1 and 2 premiums without a large loss in revenue due to grading Select or Standard. Under cash pricing, cattle are fed for very long periods because there are no discounts applied to the carcasses and, therefore, the more weight they gain, the more revenue they generate. During periods of low feed prices, cattle can be fed longer so more cattle grade Prime but also have more Yield Grade 4 and 5 cattle.

Role of gonadotropin-releasing hormone in the ovarian cells

Publisher: name: University of British Columbia
Year: 2009

description: Considering the extrapituitary roles for gonadotropin-releasing hormone (GnRH) in reproductive tissues, the present study investigated role of GnRH in the ovarian cells. The GnRH and GnRH receptor (GnRHR) mRNA were expressed and autoregulated in a biphasic mariner by a GnRH agonist (GnRH-a) in human ovarian surface epithelium (hOSE) cells and an ovarian cancer cell line, OVCAR-3. The GnRH-a had a receptor-mediated growth inhibitory effect in both cell types. The growth inhibitory effect was associated with apoptosis in OVCAR-3 cells. In addition, 17β-estradiol induced a significant down-regulation of GnRH mRNA in OVCAR-3, but not in hOSE cells and of GnRHR mRNA in both hOSE and OVCAR-3 cells. Pre- or cotreatment with 17β-estradiol significantly attenuated the growth inhibitory effect of the GnRH-a in OVCAR-3 cells, but not in hOSE cells. These results strongly support the presence of functional autocrine GnRH/GnRHR loop and potential interaction with estrogen/estrogen receptor. The GnRH-a stimulated MAPK activation in human granulosa-luteal cells (hGLCs) via a PKC-dependent pathway, which mediated the inhibitory effect of GnRH-a in progesterone secretion. The GnRH-a also stimulated MAPK activation in OVCAR-3 cells, normal placenta-derived cells (IEVT) and placental carcinoma (JEG-3) cells. The GnRH-induced MAPK activation mediated the growth inhibitory effect of GnRH-a in OVCAR-3 cells, but not the stimulatory effect of GnRH-a on the hCG mRNA level in JEG-3 cells. These results demonstrated that GnRH stimulated MAPK activation that mediated the cellular functions of GnRH in normal and neoplastic cells of human ovary. The present study demonstrates that one mechanism by which cell-specific expression of the human GnRHR is achieved is through the binding of distinct cell-specific regulatory factors to various promoter elements in the 5'-flanking region of the gene. In this study, the second form of GnRH (GnRH-II) and GnRH-I differentially regulated GnRHR and its ligands. Gonadotropins also differentially regulated GnRH-II and GnRH-I mRNA levels. GnRH-II inhibited basal and hCG-stimulated progesterone secretion. The antigonadotropic effect of GnRH-II was mediated through down-regulating gonadotropin receptors without affecting cAMP levels. In summary, on the basis of the expression, differential regulation and/or functional roles of GnRH, our studies strongly support the notion that an intrinsic GnRH axis plays an important role in regulating normal and malignant ovarian cell functions.

description: King and Ruskai asked whether the $p\to q$ norm of a completely positive map $Φ$, acting between Schatten $p$ and $q$ classes of self-adjoint operators, $||Φ||_{p\to q} = \max_{A=A^*} \frac{||Φ(A)||_q}{||A||_p}$, is equal to the $p\to q$ norm of that map when acting between Schatten classes of general, not necessarily self-adjoint, operators. The first proof has been given by Watrous. We give an alternative proof of this statement.

description: Crucial part of the estimation of construction waste (CW) is a reliable quantification of the amounts of materials needed for building construction. In this research the use of Building Information Modeling (BIM) is proposed as a solution for retrieving project data effectively for CW estimation purposes. Two algorithms that were developed to quantify concrete and drywall waste are presented to demonstrate a proposed CW estimation methodology. The main idea of this methodology is that the portion of materials purchased that are not needed to be incorporated into the actual structure are considered waste. The amounts of materials purchased are available on general contractors purchasing records and amounts of materials needed for construction are retrieved from BIM models. This research uses the BIM model of a recently completed institutional building as a testbed to perform the waste estimation. The validation of the proposed algorithms is performed by comparing the estimated waste to actual waste data from the project. Furthermore, numbers found on the literature are used to validate these estimations. This study is part of a larger ongoing project that seeks to develop algorithms for the estimation of the major CW streams and implement them to enable a fully automated estimation

description: Corn price differentials among Illinois elevators can often exceed transportation costs. Using primary data, we examine the effects of micro-market structure variables on the differentials in bids prices offered by Illinois elevators. Our findings suggest the existence of a highly developed, responsive market of competing firms, operating in an industry that can be characterized by monopsonistic competition, and to some extent by seasonally induced market power. Local supply conditions, firm productive efficiency, and their operating practices influence price differentials. Further, firm type, final market destination of the grain, and period of the marketing year affect price differentials.

description: The in-plane current profile within multilayers of generic structure Ta/Pt/(CoNi)/Pt/Ta is investigated. A large set of samples where the thickness of each layer is systematically varied was grown, followed by the measurement of the sheet resistance of each sample. The data are analyzed by a series of increasingly elaborate models, from a macroscopic engineering approach to mesoscopic transport theory. Non-negligible variations of the estimated repartition of current between the layers are found. The importance of having additional structural data is highlighted.

description: OGLE-2004-BLG-343 was a microlensing event with peak magnification A_{max}=3000+/-1100, by far the highest-magnification event ever analyzed and hence potentially extremely sensitive to planets orbiting the lens star. Due to human error, intensive monitoring did not begin until 43 minutes after peak, at which point the magnification had fallen to A~1200, still by far the highest ever observed. As the light curve does not show significant deviations due to a planet, we place upper limits on the presence of such planets by extending the method of Yoo et al. (2004b), which combines light-curve analysis with priors from a Galactic model of the source and lens populations, to take account of finite-source effects. This is the first event so analyzed for which finite-source effects are important, and hence we develop two new techniques for evaluating these effects. Somewhat surprisingly, we find that OGLE-2004-BLG-343 is no more sensitive to planets than two previously analyzed events with A_{max}~100, despite the fact that it was observed at ~12 times higher magnification. However, we show that had the event been observed over its peak, it would have been sensitive to almost all Neptune-mass planets over a factor of 5 of projected separation and even would have had some sensitivity to Earth-mass planets. This shows that some microlensing events being detected in current experiments are sensitive to very low-mass planets. We also give suggestions on how extremely high-magnification events can be more promptly monitored in the future.

description: The purpose of this paper is to investigate the performance of agricultural market advisory services in marketing wheat. Two key performance questions are addressed: 1) Do market advisory services, on average, outperform an appropriate wheat market benchmark? and 2) Do market advisory services exhibit persistence in their wheat performance from year-to-year? Market advisory service recommendations for wheat are available from the AgMAS Project for the 1995, 1996, 1997 and 1998 marketing years. At least 20 advisory programs are included for each year. Tests of pricing performance relative to a market benchmark are based on the proportion of programs exceeding the benchmark price and the average percentage difference between the net price of advisory programs and the benchmark price. In statistical terms, the pricing performance test results are clear. Not only do market advisory programs in wheat consistently fail to "beat the market," their performance is significantly worse than the market. The level of under-performance is striking and consistent, with the proportion of programs above market benchmarks for the four-year period ranging from 0.34 to 0.38. Estimates of the four-year average return relative to market benchmarks range from -9.61 to -10.48 percent. Tests of predictability are based on the correlation of performance measures for overlapping and non-overlapping adjacent marketing years. In general, the predictability results provide little evidence that future advisory program pricing performance can be usefully predicted from past performance. On average, correlations are positive for overlapping years (e.g. 1995 vs. 1996). However, correlations tend to be negative for non-overlapping years (e.g. 1995 vs. 1997), which implies that producers selecting top-performing programs based on a given year, and expecting them to continue to be top-performing funds, would actually experience just the opposite result.

description: The Commodity Futures Trading Commission's Commitments of Traders data are examined. Non-commercial positions are thought to contain the least amount of measurement error. Although non-commercials comprise a relatively small percent of the tested markets' open interest (10% to 22%), they have the most volatile net positions. The data demonstrates a statistically (positive) negative contemporaneous correlation between net positions held by (non) commercials and market returns. However, traders' net positions do not lead (Granger cause) market returns. In fact, returns lead traders' net positions. Positive returns result in an (increase) decrease in (non) commercials net positions the following week. The findings suggest that prior empirical results, which make assumptions about traders' positions not changing over a reporting interval, may be biased toward reflecting the contemporaneous position-return correlations reported in this research.

description: We present an algorithmic classification of the irreps of the $N$-extended one-dimensional supersymmetry algebra linearly realized on a finite number of fields. Our work is based on the 1-to-1 \cite{pt} correspondence between Weyl-type Clifford algebras (whose irreps are fully classified) and classes of irreps of the $N$-extended 1D supersymmetry. The complete classification of irreps is presented up to $N\leq 10$. The fields of an irrep are accommodated in $l$ different spin states. N=10 is the minimal value admitting length $l>4$ irreps. The classification of length-4 irreps of the N=12 and {\em real} N=11 extended supersymmetries is also explicitly presented.\par Tensoring irreps allows us to systematically construct manifestly ($N$-extended) supersymmetric multi-linear invariants {\em without} introducing a superspace formalism. Multi-linear invariants can be constructed both for {\em unconstrained} and {\em multi-linearly constrained} fields. A whole class of off-shell invariant actions are produced in association with each irreducible representation. The explicit example of the N=8 off-shell action of the $(1,8,7)$ multiplet is presented.\par Tensoring zero-energy irreps leads us to the notion of the {\em fusion algebra} of the 1D $N$-extended supersymmetric vacua.
description: Final version to appear in JHEP. 52 pages. The part with the complete classification of irreps (and the explicit presentation of length-4 irreps of N=9,10,11,12 and N=10 length-5 irreps) is unchanged. An extra section has been added with an entire class of off-shell invariant actions for arbitrary values N of the 1D extended supersymmetry. A non-trivial N=8 off-shell action for the (1,8,7) multiplet has been constructed as an example. It is obtained in terms of the octonionic structure constants

description: This research examines the returns to a cattle feeding operation that sorts animals prior to marketing using ultrasound technology. The returns to sorting are between $11 and $25 per head depending on the number of groups the pens in which cattle can be sorted. Sorting faces declining returns. These returns can also be viewed as the costs imposed by institutional constraints that limit co-mingling of cattle. Through sorting, cattle feeding operations are able to reduce meat quality discounts, increase meat quality premiums, increase beef carcass quality characteristics, more efficiently use feed resources, and increase profits.

description: Changes in the chemical and isotopic composition of the solar nebula with time are reflected in the properties of different constituents that are preserved in chondritic meteorites. CR carbonaceous chondrites are among the most primitive of all chondrite types and must have preserved solar nebula records largely unchanged. We have analyzed the oxygen and magnesium isotopes in a range of the CR constituents of different formation temperatures and ages, including refractory inclusions and chondrules of various types. The results provide new constraints on the time variation of the oxygen isotopic composition of the inner (<5 AU) solar nebula - the region where refractory inclusions and chondrules most likely formed. A chronology based on the decay of short-lived 26Al (t1/2 ~ 0.73 Ma) indicates that the inner solar nebula gas was 16O-rich when refractory inclusions formed, but less than 0.8 Ma later, gas in the inner solar nebula became 16O-poor and this state persisted at least until CR chondrules formed ~1-2 Myr later. We suggest that the inner solar nebula became 16O-poor because meter-size icy bodies, which were enriched in 17,18O due to isotopic self-shielding during the ultraviolet photo dissociation of CO in the protosolar molecular cloud or protoplanetary disk, agglomerated outside the snowline, drifted rapidly towards the Sun, and evaporated at the snowline. This led to significant enrichment in 16O-depleted water, which then spread through the inner solar system. Astronomical studies of the spatial and/or temporal variations of water abundance in protoplanetary disks may clarify these processes.

Using daily corn and soybean basis data between 1993 and 1999 for multiple locations in Missouri, and incorporating a variable for when the LDP was in effect during 1998 and 1999, empirical models examining factors affecting corn and soybean basis were estimated. Results indicate that the presence of the LDP program has not had a significant economic impact on corn or soybean basis during the 1998 to 1999 period. Furthermore, factors affecting corn and soybean basis varied by time within the marketing year.

description: Detailed modelling of stellar oscillations is able to give precise estimates for stellar ages, but the inferred results typically depend on the adopted model parameters used for the age inference. High-quality asteroseismic data with precise measurements of mixed modes are available for 36 Kepler subgiants. To obtain a handle on the robustness of the ages for these stars, we first study the dependencies of seismic ages on three model input parameters. We find that inferred ages do not change systematically with the helium fraction (Y) or the mixing-length parameter but depend strongly on the metallicity ([M/H]) of the model. The results indicate that age estimates of subgiants have less model dependence and hence are more reliable than those of main-sequence stars or red giants. We then model individual oscillation frequencies of the same 36 Kepler subgiants, using observed metallicities, and obtain their ages with an average precision of ~15%. The comparison with previous age estimates with different stellar codes or input physics shows good agreement (mostly within 2#). We hence suggest that seismology-determined ages of subgiants are not greatly model-dependent.

description: In developing optimal hedge ratios for the soybean processing margin, many authors have illustrated the importance of considering the interactions between the cash and futures prices for soybeans, soybean oil, and soybean meal. Conditional as well as time-varying hedge ratios have been examined, but in the case of multiproduct time-varying hedge ratios, the difficulty in estimation has been found to often outweigh any improvement in hedging effectiveness. This research examines the hedging effectiveness of the Risk Metrics procedure for estimating a time-varying covariance matrix for developing optimal hedge ratios for the soybean processing margin. The Risk Metrics method allows for a time-varying covariance matrix while being considerably easier to implement than multivariate GARCH (MGARCH) procedures. The Risk Metrics procedure has been advocated for use in developing Value-at-Risk estimates. While it provided considerable out-of-sample improvement in hedging effectiveness relative to a constant correlation MGARCH procedure, the Risk Metrics method provided only minimal improvement over a naive (1-to-1) hedging strategy. However, this research does illustrate the potential for the Risk Metrics methodology as a viable alternative to MGARCH procedures in a multiproduct hedging context.

description: The research presented is part of a larger study aiming at the analysis of reform options for the EU sugar policy regime. This paper focuses on the effects of quota reduction and support price cuts. A thorough theoretical analysis investigates the implications of farm heterogeneity for aggregate supply modeling purposes under the current sugar regime. It can be shown that the treatment of sugar quantities produced under the different quotas and without quota can be treated as different products in an aggregate profit function analysis. Marginal and discrete price and quota effects are derived. Subsequently, the derived behavioral characteristics are implemented in the framework of the agricultural sector model CAPSIM to provide a broader policy evaluation. Preliminary simulation results are presented for the EU at aggregate level.

description: Hydrogen bonding in infinite HF and HCl bent (zigzag) chains is studied using the ab initio coupled-cluster singles and doubles (CCSD) correlation method. The correlation contribution to the binding energy is decomposed in terms of nonadditive many-body interactions between the monomers in the chains, the so-called energy increments. Van der Waals constants for the two-body dispersion interaction between distant monomers in the infinite chains are extracted from this decomposition. They allow a partitioning of the correlation contribution to the binding energy into short- and long-range terms. This finding affords a significant reduction in the computational effort of ab initio calculations for solids as only the short-range part requires a sophisticated treatment whereas the long-range part can be summed immediately to infinite distances.

description: Little attention has been given to the process of development that leads to alliance relationships flexible enough to withstand unforeseen environmental shifts and evolve while others fail. We believe that the problem stems from the contractual rigidity imposed by partners in the initial stages to the formation of an alliance. This paper analyzes a process to create self-enforcing agreements that lead to a flexible alliance architecture capable of reconfiguration to meet the demands of environmental change. Using an empirical case study of "Cellars of Canterbury" a New Zealand wine producing and marketing joint venture, we suggest that immediate value creation establishes private enforcement capital in a relationship which allows for critical relation-specific investment to take place without the need for written contractual safeguards. We also emphasize the advantage of external contract enforcement mechanisms and third party verification in reinforcing these relationships. We then argue that it is this lack of contractual rigidity that allows an alliance agreement to be reconfigured when environmental circumstances change.

description: This paper summarizes research into the factors contributing to these low levels of adoption of improved maize varieties in Honduras. Empirical results indicate that transactions costs and production characteristics are important explanators of variety choice, consumption characteristics are not, and information deficits are an important limiting factor to HYV adoption.

description: The Environmental Benefits Index (EBI) ranks Conservation Reserve Program (CRP) offers by weighing program costs for enrolling land in CRP against six environmental objectives. This paper uses Monte Carlo simulations to analyze the sensitivity of CRP enrollment outcome to the specification of the EBI. Results indicate that:(a)there is no major shift in average benefits throughout the U.S. when marginal changes in the weights occur, and (b) priority area weights, whether National or State, play a role in shifting CRP away from its traditional focus on highly erodible land, and (c) there is complementarity between the enduring benefits and the wildlife objectives and substitutability between the enduring benefits and the erosion reduction objectives;

description: Shannon information entropies in position and momentum spaces and their sum are calculated as functions of Z (Z=2-54) in atoms. Roothaan-Hartree-Fock electron wave functions are used. The universal property S=a+b lnZ is verified. In addition, we calculate the Kullback-Leibler relative entropy, the Jensen-Shannon divergence, Onicescu's information energy and a complexity measure recently proposed. Shell effects at closed shells atoms are observed. The complexity measure shows local minima at the closed shells atoms indicating that for the above atoms complexity decreases with respect to neighboring atoms. It is seen that complexity fluctuates around an average value, indicating that the atom cannot grow in complexity as Z increases. Onicescu's information energy is correlated with the ionization potential. Kullback distance and Jensen-Shannon distance are employed to compare Roothaan-Hartree-Fock density distributions with other densities of previous works.

description: Within the simultaneous message passing model of communication complexity, under a public-coin assumption, we derive the minimum achievable worst-case error probability of a classical fingerprinting protocol with one-sided error. We then present entanglement-assisted quantum fingerprinting protocols attaining worst-case error probabilities that breach this bound.

description: This research uses laboratory experiments to test alternative water market institutions designed to protect third-party interests. The institutions tested include taxing mechanisms that raise revenue to compensate affected third-parties, and a free market in which third-parties actively participate. We also discuss the likely implications of a command-and-control approach in which there are fixed limits on the volume of water that may be exported from a region. The results indicate that there are some important trade-offs in selecting a policy option. Although theoretically optimal, active third-party participation in the market is likely to result in free-riding that may erode some or all of the efficiency gains, and may introduce volatility into the market. Fixed limits on water exports are likely to result in a more stable market, but the constraints on exports will result in lower levels of social welfare. Taxing transfers and compensating third-parties offers a promising balance of efficiency, equity and market stability.

description: An unstable grasp pose can lead to slip, thus an unstable grasp pose can be predicted by slip detection. A regrasp is required afterwards to correct the grasp pose in order to finish the task. In this work, we propose a novel regrasp planner with multi-sensor modules to plan grasp adjustments with the feedback from a slip detector. Then a regrasp planner is trained to estimate the location of center of mass, which helps robots find an optimal grasp pose. The dataset in this work consists of 1 025 slip experiments and 1 347 regrasps collected by one pair of tactile sensors, an RGB-D camera and one Franka Emika robot arm equipped with joint force/torque sensors. We show that our algorithm can successfully detect and classify the slip for 5 unknown test objects with an accuracy of 76.88% and a regrasp planner increases the grasp success rate by 31.0% compared to the state-of-the-art vision-based grasping algorithm.

Evaluation of community empowerment in a community-based health promotion partnership

description: A qualitative evaluation of community empowerment in a community-based health promotion project, Hand-In-Hand, was completed. Hand-In-Hand offers a free weekly drop-in service where families are able to access information and services pertaining to their health and developmental issues. The project was developed by a steering committee comprised of health care providers and community members to address two main concerns expressed by community women: difficulty accessing health information and services, and a perceived lack of respect from the health care system. Four community women, members of the Hand-In-Hand steering committee, were interviewed for the study. The data from the interviews was analyzed using the qualitative research methods of inductive content analysis and constant comparative analysis. The findings indicated that six phases were instrumental in the process of community empowerment: initial involvement, building relationships, demonstrating commitment, building partnerships, achieving individual empowerment, and increasing community capacity. Outcomes related to each of the phases were identified. The process of community empowerment was iterative rather than linear. The participants moved freely between the phases as they proceeded to the final phase of community empowerment. The process and outcomes of community empowerment have implications for nursing research, practice, education, and administration, along with health policy. The lessons learned from this study should contribute to a better understanding of the process of community empowerment, education of community health practitioners, and support of community initiatives by health care administrators and leaders.

description: In this paper, we study the problem of designing prefix-free encoding schemes having minimum average code length that can be decoded efficiently under a decode cost model that captures memory hierarchy induced cost functions. We also study a special case of this problem that is closely related to the length limited Huffman coding (LLHC) problem; we call this the {\em soft-length limited Huffman coding} problem. In this version, there is a penalty associated with each of the $n$ characters of the alphabet whose encodings exceed a specified bound $D$($\leq n$), where the penalty increases linearly with the length of the encoding beyond $D$. The goal of the problem is to find a prefix-free encoding having minimum average code length and total penalty within a pre-specified bound ${\cal P}$. This generalizes the LLHC problem. We present an algorithm to solve this problem that runs in time $O( nD )$. We study a further generalization in which the penalty function and the objective function can both be arbitrary monotonically non-decreasing functions of the codeword length. We provide dynamic programming based exact and PTAS algorithms for this setting.
