description: In recent years, arrays of atomic ions in a linear RF trap have proven to be a particularly successful platform for quantum simulation. However, a wide range of quantum models and phenomena have, so far, remained beyond the reach of such simulators. In this work we introduce a technique that can substantially extend this reach using an external field gradient along the ion chain and a global, uniform driving field. The technique can be used to generate both static and time-varying synthetic gauge fields in a linear chain of trapped ions, and enables continuous simulation of a variety of coupling geometries and topologies, including periodic boundary conditions and high dimensional Hamiltonians. We describe the technique, derive the corresponding effective Hamiltonian, propose a number of variations, and discuss the possibility of scaling to quantum-advantage sized simulators. Additionally, we suggest several possible implementations and briefly examine two: the Aharonov-Bohm ring and the frustrated triangular ladder.

description: We examined the cation selectivity of the Saalfrank-type {2}-metallocryptands [Ga2R3] and [Fe2R3] (R: 1,1'-(pyridine-2,6-diyl)bis(2-(1H-tetrazol-5-yl)ethan-1-one)) with alkaline and earth alkaline metal ions by means of DFT calculations (B3LYP/LANL2DZp) to obtain a better insight into the influence of the bridge head metal ions responsible for the cryptands ion selectivity. Based on our DFT calculations, notably the application of model equations and geometric features regarding the flexibility of the {2}-metallocryptands, we identified K+, Sr2+ and Ba2+ as the best fitting ions. While [Fe2R3] has a cavity a bit larger than [Ga2R3], it prefers the Ba2+ cation, whereas [Ga2R3] selects the smaller Sr2+ cation. The good flexibility of the investigated hosts is provided by the oxygen-donor moieties of the {2}-metallocryptands.
Low mu and imaginary mu signals of a critical point in the phase diagram of an exactly soluble chiral symmetry breaking theory

description: Holography has allowed the exact solution of a small number of large Nc gauge theories. Amongst these is an N=2 SYM theory of quarks interacting with N=4 gauge fields. The temperature chemical potential phase diagram for this theory in the presence of a magnetic field is exactly known and shows first and second order chiral symmetry restoration transitions and a critical point. Here we extend this phase diagram to imaginary chemical potential to seek structure at small real mu and imaginary mu that help to reconstruct the large real mu phase structure. We also explore a phenomenologically deformed version of the theory where the critical point can be moved into the imaginary chemical potential plane. In particular we observe that when the transition is second order in these theories there are naturally two distinct transitions - one for the onset of density and one for chiral symmetry restoration. In addition, the phase diagram has boundaries of regions where metastable vacua exist and these boundaries, as well as the phase boundaries, converge at the critical point. These observations may point to techniques for the study of the QCD critical point either on the lattice or using heavy ion collision data.

description: Public debate on biotechnology is embroiled in controversy over the risks and benefits associated with this emerging technology. Using data from a national survey, this study analyzes public acceptance of biotechnology in food production. Empirical results suggest that while there is general optimism about biotechnology, and support for its use in plants, public approval of its use in animals is perhaps more limited. Younger and more educated individuals are generally more supportive of biotechnology. Attitudes towards biotechnology differ substantially between males and females, and between whites and non-whites. While people's religious and social views, confidence in scientists, corporations and government have significant influence, income and regional differences do not have significant effects on public acceptance of biotechnology.

description: A thiazole-based chalconoid ligand (E)-3-(2-hydroxyphenyl)-1-(thiazol-2-yl)prop-2-en-1-one (HPTP) and its Co(II), Ni(II), Cu(II) and Zn(II) complexes have been synthesized. The synthesized compounds were characterized by elemental analysis, molar conductance, UV-vis., FT-IR, NMR, mass spectral techniques, magnetic susceptibility, powder XRD and SEM with EDAX. In addition, the structures were optimized with Density Functional Theory (DFT) computations. The Lewis base nature of HPTP, stability on coordination, charge transfer interactions, quantum chemical parameters and vibrational frequencies were analyzed. The molecules were docked with 5FX6 receptor as possible inhibitors of human rhinovirus (HRV) 3 C protease.
Early photon-shock interaction in stellar wind: sub-GeV photon flash and high energy neutrino emission from long GRBs

description: For gamma-ray bursts (GRBs) born in a stellar wind, as the reverse shock crosses the ejecta, usually the shocked regions are still precipitated by the prompt MeV γ-ray emission. Because of the tight overlapping of the MeV photon flow with the shocked regions, the optical depth for the GeV photons produced in the shocks is very large. These high energy photons are absorbed by the MeV photon flow and generate relativistic e^\pm pairs. These pairs re-scatter the soft X-ray photons from the forward shock as well as the prompt γ-ray photons and power detectable high energy emission, significant part of which is in the sub-GeV energy range. Since the total energy contained in the forward shock region and the reverse shock region are comparable, the predicted sub-GeV emission is independent on whether the GRB ejecta are magnetized (in which case the reverse shock IC and synchrotron self-Compton emission is suppressed). As a result, a sub-GeV flash is a generic signature for the GRB wind model, and it should be typically detectable by the future {\em Gamma-Ray Large Area Telescope} (GLAST). Overlapping also influence neutrino emission. Besides the 10^{15} \sim 10^{17} eV neutrino emission powered by the interaction of the shock accelerated protons with the synchrotron photons in both the forward and reverse shock regions, there comes another $10^{14}$eV neutrino emission component powered by protons interacting with the MeV photon flow. This last component has a similar spectrum to the one generated in the internal shock phase, but the typical energy is slightly lower.

Using our data collection pipeline, we collect and examine the interpretation of songs in both the American Sign Language (ASL) and the Brazilian Sign Language (Libras). We explore their differences and similarities by looking at the co-dependence of the orientation and location phonological parameters

description: Background: Renal stones can form in different parts of the urinary system, including the kidneys, ureters, bladder, and urethra. The stones are typically composed of minerals and salts that have crystallized and fused together. Renal stone is often associated with factors such as an imbalance in the substances that make up urine, leading to the precipitation and aggregation of minerals. The stones can vary in size, and their presence in the urinary tract can cause symptoms ranging from mild discomfort to severe pain, depending on the location and size of the stones.

Objective: This review will review the most recent medical literature on renal stone etiology, management, and recommendations.

Methods: Comprehensive research on the renal stone etiology, management, and recommendations. PUBMED and Google Scholar search engines were the databases used for the search process, and articles were collected from 2000 to 2023. The term used in the search were: renal stone, etiology, pathophysiology, management, prevention.

Conclusion: Renal stone, or urolithiasis, involves the formation of stones in the urinary tract, posing a common health issue with multifactorial causes. Mechanisms include a urine biochemical imbalance, leading to supersaturation, nucleation, and crystal aggregation. Presentations range from asymptomatic to painful symptoms. Surgical management prevails, but the rising prevalence poses health and economic challenges. Stone types like calcium oxalate, calcium phosphate, uric acid, struvite, and cystine have distinct etiologies involving metabolic syndrome, genetic factors, and various medical conditions. Diagnosis integrates clinical evaluation and imaging, primarily non-contrast CT scans. Treatments include NSAIDs, surgical interventions, and homeopathic options. Prevention emphasizes lifestyle changes, dietary modifications, and medication use.

Keywords: renal stone, etiology, pathophysiology, management, prevention.
Measurement of the Form-Factor Slopes for the Decay KLe3 with the KLOE Detector

description: We present a measurement of the K-pi vector current form-factor parameters for the Ke3 decay. We use 328 pb$^{-1}$ of data collected in 2001 and 2002, corresponding to about 2 million Ke3 events. Measurements of semileptonic form factors provide information about the dynamics of the strong interaction and are necessary for evaluation of the phase-space integral Ie_K needed to measure the CKM matrix element Vus for Ke3 decays. Our result is $l=(28.6\pm0.5\pm0.4)10^{-3}$ for a linear fit, and $l'=(25.5\pm1.5\pm1.0)10^{-3}$, $l''=(1.4\pm0.7\pm0.4)10^{-3}$ for a quadratic fit.

description: A heptadentate N 4 O 3 coordinated dinuclear zinc complex was synthesized. The sensor functioned as a “turn-on” fluorescence receptor only to Zn2+ ion in 3:2 v/v MeOH/water in HEPES buffer at pH 7.2 at 25 °C. A huge increase in emission intensity (approximately 200 times) of the ligand was observed in the presence of Zn2+ which was accounted for by the formation of a metal-ligand complex and thus could be used as zinc ion-selective luminescent probe, continuously emitting blue light in the presence of a UV lamp. The theoretically optimized geometry in solution state gives an idea about bond relaxation as well as change the geometric scenario of the coordinated metal ion from trigonal bipyramidal to square pyramidal.

AN EVOLUTIONARY TRADE NETWORK GAME WITH PREFERENTIAL PARTNER SELECTION

Year: 1996
Subjects: International Relations/Trade

description: An evolutionary trade network game (TNG) is proposed for studying the interplay between evolutionary game dynamics and preferential partner selection in various market contexts with distributed adaptive agents. The modular form of the TNG facilitates experimentation with alternative specifications for trade partner matching, trading, expectation up dating, and trade strategy evolution. Experimental results obtained using a C++ implementation suggest that the conventional optimality properties used to evaluate agent matching mechanisms in static market contexts maybe inadequate measures of optimality from an evolutionary perspective.

The flux-weighted gravity-luminosity relation of Galactic classical Cepheids

Publisher: name: arXiv
Year: 2020
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

subject: FOS: Physical sciences

description: The flux-weighted gravity-luminosity relation (FWGLR) is investigated for a sample of 477 classical Cepheids (CCs), including stars that have been classified in the literature as such but are probably not. The luminosities are taken from the literature, based on the fitting of the spectral energy distributions (SEDs) assuming a certain distance and reddening. The flux-weighted gravity (FWG) is taken from gravity and effective temperature determinations in the literature based on high-resolution spectroscopy. There is a very good agreement between the theoretically predicted and observed FWG versus pulsation period relation that could serve in estimating the FWG (and $\log g$) in spectroscopic studies with a precision of 0.1~dex. As was known in the literature, the theoretically predicted FWGLR relation for CCs is very tight and is not very sensitive to metallicity (at least for LMC and solar values), rotation rate, and crossing of the instability strip. The observed relation has a slightly different slope and shows more scatter (0.54~dex). This is due both to uncertainties in the distances and to the pulsation phase averaged FWG values. Data from future Gaia data releases should reduce these errors, and then the FWGLR could serve as a powerful tool in Cepheid studies.

description: Using 1971-2000 data, we examine the accuracy of corn and soybean production forecasts provided by the USDA and two private services. All agencies improved their forecasts as the harvest progressed, and forecast errors across the agencies were highly correlated. Relative accuracy varied by crop and month. In corn, USDA 's forecasts ranked as most accurate in all periods except in August during recent times, and improved more markedly as harvest progressed. In soybeans, forecast errors were very similar with the private agencies ranking as most accurate in August and September and making largest relative improvements in August during recent times. The USDA provided the most accurate October and November forecasts.

description: The enantiopure Schiff bases (R or S)-1-(p-R1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamine (R1 = H and OCH3) are synthesized from reaction between the 2-benzoyl-pyridine and chiral-amine (R or S)-1-(p-R1-C6H4)ethylamine, respectively. These Schiff bases react with the copper(II) acetate to give distorted-tetrahedral bis[(R or S)-1-(p-R1-C6H4)-N-(phenyl(pyridin-2-yl)methylene)ethanamino-κ2 N,N]-Δ/Λ-Cu(PF6)2 in the presence of NH4PF6. A conformational change from cis- to trans-isomer occurs in solution and thereby, the copper(II) coordinates to the solely trans-form to provide the complexes. Cyclic voltammograms demonstrate two quasi-reversible one electron charge transfer processes for the Cu2+/Cu+ and Cu+/Cu0 couples in acetonitrile. ECD spectra reveal expected mirror-image relationships and indicate enantiopurity or enantiomeric excess of the R or S-ligands and their associated complexes in solution. Comparisons of experimental and simulated ECD spectra suggest induced chirality at-metal center, which diastereoselectively provides the Δ-Cu-R or Λ-Cu-S diastereomer as major product in solution. DFT/TDDFT optimized structures and excited state properties correspond well to the experimental results.

description: This research presents an intuitive interpretation and expression for pricing cash settled futures contracts. In particular, the choice of the averaging period for the underlying cash index is evaluated. For example, the averaging period for the Lean Hog futures contract is two days, whereas it is thirty days for the F ed funds contract. Does the choice of the averaging period make a difference? Under certain assumptions, the behavior of the futures price prior to entering the expiration or averaging interval is independent of the length of the interval for storable commodities, but it is not for non-storable commodities.

description: The demand for hedging against price uncertainty in the presence of crop yield and revenue insurance contracts is examined for French wheat farms. The rationale for the use of options in addition to futures is first highlighted through the characterization of the first-best hedging strategy in the expected utility framework. It is then illustrated using numerical simulations. The presence of options is shown to allow the insured producer to adopt a more speculative position on the futures market. Futures are shown to be performing, in terms of willingness to receive. Options are weakly performing when futures markets are unbiased, while they are more performing when futures markets are biased.
Transit least-squares survey -- III. A $1.9\,R_\oplus$ transit candidate in the habitable zone of Kepler-160 and a nontransiting planet characterized by transit-timing variations

description: The Sun-like star Kepler-160 (KOI-456) has been known to host two transiting planets, Kepler-160 b and c, of which planet c shows substantial transit-timing variations (TTVs). We used the archival Kepler photometry of Kepler-160 to search for additional transiting planets using a combination of our Wotan detrending algorithm and our transit least-squares (TLS) detection algorithm. We also used the Mercury N-body gravity code to study the orbital dynamics of the system. First, we recovered the known transit series of planets Kepler-160 b and c. Then we found a new transiting candidate with a radius of 1.91 (+0.17, -0.14) Earth radii (R_ear), an orbital period of 378.417 (+0.028, -0.025) d, and Earth-like insolation. The vespa software predicts that this signal has an astrophysical false-positive probability of FPP_3 = 1.8e-3 when the multiplicity of the system is taken into account. Kepler vetting diagnostics yield a multiple event statistic of MES = 10.7, which corresponds to an ~85 % reliability against false alarms due to instrumental artifacts such as rolling bands. We are also able to explain the observed TTVs of planet c with the presence of a previously unknown planet. The period and mass of this new planet, however, do not match the period and mass of the new transit candidate. Our Markov chain Monte Carlo simulations of the TTVs of Kepler-160 c can be conclusively explained by a new nontransiting planet with a mass between about 1 and 100 Earth masses and an orbital period between about 7 and 50 d. We conclude that Kepler-160 has at least three planets, one of which is the nontransiting planet Kepler-160 d. The expected stellar radial velocity amplitude caused by this new planet ranges between about 1 and 20 m/s. We also find the super-Earth-sized transiting planet candidate KOI-456.04 in the habitable zone of this system, which could be the fourth planet.

description: Matching the timing of spring arrival to the breeding grounds with hosts and prey is crucial for migratory brood parasites such as cuckoos. Previous studies have focused mostly on phenological mismatch between a single cuckoo species and its hosts but information regarding climate-driven mismatch between multiple sympatric cuckoo species and their hosts and invertebrate prey is still lacking. Here, we analysed long-term data (1988–2023) on the first arrival date of two declining migratory cuckoo species and their 14 migratory host species breeding in sympatry and prey emergence date in Tatarstan (southeast Russia). We found that the common cuckoo (Cuculus canorus; wintering in Africa) generally arrived on breeding grounds earlier than the oriental cuckoo (Cuculus optatus; wintering in southeast Asia and Australia). Both cuckoos have advanced their arrival dates over 36 years but less than their hosts, potentially resulting in an increasing arrival mismatch between cuckoos and their hosts. Moreover, cuckoo arrival advanced less than the emergence date of their prey over time. These observations indicate that climate change may disrupt co-fluctuation in the phenology of important life stages between multiple sympatric brood parasites, their hosts and prey with potential cascading consequences for population dynamics of involved species.

description: Agricultural risk managers need forecasts of price volatility that are accurate and meaningful. This is especially true given the greater emphasis on firm level risk measurement and management (e.g., Value-at-Risk and Enterprise Risk Management). Implied volatility is known to provide a readily available, market based forecast of volatility. Because of this, it is often considered to be the "best" available (e.g., optimal) volatility forecast. However, many studies have provided evidence contrary to this claim for many markets (Figlewski). This research examines the forecasting performance of implied volatility derived from the Black-1976 option pricing model in predicting 1-week volatility of nearby live cattle futures prices. Unlike many studies of implied volatility, this research takes a practical approach to evaluating implied volatility, namely from the perspective of an agribusiness risk manager who uses implied volatility in risk management applications, and thus needs to understand its forecasting performance. This research also uses a methodology that avoids overlapping forecast horizons. As well, the methodology focuses on forecast errors that can reduce interpretive issues that can arise from traditional forecast evaluation procedures. Results suggest that implied volatility derived from nearby options contracts on live cattle futures is a biased and inefficient forecast of 1-week nearby futures price volatility, but encompasses all information provided by a time series forecast (i.e., GARCH). As well, our results suggest that implied volatility has improved as a forecast of 1-week volatility over time. These results provide practical information to risk managers on the bias, efficiency, and information content of implied volatility from live cattle options markets, and provide practical suggestions on how to adjust the bias and inefficiency that is found in this forecasting framework.

description: The vast majority of previous studies on farmers' optimal risk management behavior have used static models and on the most part ignored use of borrowing and lending as an alternative method of managing risk In this paper we develop a stylized multi-period risk management model for a risk averse farmer who can use revenue insurance to manage risk and also borrow and lend subject to a credit constraint. The model is applied to an example farm from Adair County in Iowa and the results provide three important messages. First, contrary to the full coverage of actuarially fair insurance result expected from using purely static analysis, at low revenues, insurance coverage may not be taken in the absence of debt. Second, if debt is available, full coverage will be taken at all revenue states and, third, premium wedges at reasonable levels have larger impact on coverage if debt is available because they eliminate the incentive to use insurance. Results also show that use of borrowing and lending for consumption smoothing reduces extant risk by approximately 77% while use of insurance only reduces risk by approximately 30%.

description: This paper discusses some of the failings of expected utility including the Allais paradox and expected utility's inadequate one dimensional characterization of risk. Three alternatives to expected utility are discussed at length; weighted expected utility, rank dependent utility, and cumulative prospect theory. Each alternative is capable of explaining Allais paradox type problems and permits more sophisticated multi dimensional risk preferences.

description: We study the equivalence problem of submanifolds with respect to a transitive pseudogroup action. The corresponding differential invariants are determined via formal theory and lead to the notions of k-variants and k-covariants, even in the case of non-integrable pseudogroup. Their calculation is based on the cohomological machinery: We introduce a complex for covariants, define their cohomology and prove the finiteness theorem. This implies the well-known Lie-Tresse theorem about differential invariants. We also generalize this theorem to the case of pseudogroup action on differential equations.

description: Accurate pricing of weather derivatives is critically dependent upon correct specification of the underlying weather process. We test among six likely alternative processes using maximum likelihood methods and data from the Fresno, CA weather station. Using these data, we find that the best process is a mean-reverting geometric Brownian process with discrete jumps and ARCH errors. We describe a pricing model for weather derivatives based on such a process.

description: In almost all of the Southern Africa Development Community (SADC) countries maize is cropped on a commercial basis except in Mauritius and Seychelles. Maize meal is the most important food staple in Southern and Eastern Africa. This is one of the main reason many governments in the region implement various policies to protect the maize sector. With adoption of the Uruguay Round Agreement on Agriculture (URAA) in the late 1990s, there has been a wave of market liberalization in the region. Maize production and marketing have seen major reforms with the URAA, market liberalization, and the Structural Adjustment Programs (SAPs). Private sector participation in the supply of maize inputs (improved seed and fertilizer) and grain marketing has steadily increased during this same period (Hassan et al., 2000). The pace of change differed however from country to country, as did the impacts of the reforms.

description: Thaba Nchu is a semi-arid area with low and erratic annual rainfall not exceeding 600mm. Various dryland crops are produced with relatively low yields and high risk of failure. Lack of appropriate technology and other constraints has led to most of the arable land being unused thus restricting agribusiness opportunities in an area where unemployment and food insecurity are thriving. Rainwater harvesting has a huge potential to increase crop yields in Thaba Nchu and reduce the risk of losses, and thus improve food security and enhance sustainability. Different in-field rainwater harvesting (IRWH) techniques have been tested and applied at Glen and Thaba Nchu. This paper gives comparative results for three crops produced with regard to relative profitability and risk of failure. This is done by integrating crop enterprise budgets with crop yield simulations models to calculate per hectare profits over an 81-year period and developing and analyzing cumulative probability functions.

description: Skeletal remains of a small reptile with a distinctive dentition from the Lower Keuper (Erfurt Formation; Middle Triassic, Ladinian) of the Schumann quarry near Eschenau, in the municipality of Vellberg in Baden-Württemberg, Germany, represent a new taxon of non-archosaurian archosauriforms, Polymorphodon adorfi. It is diagnosed by various craniodental autapomorphies, including mesial and distal carinae of labiolingually flattened maxillary and dentary tooth crowns with large, somewhat hook-shaped denticles aligned at distinct angle to apicobasal axis of tooth crown; premaxilla with long, leaf-shaped posterodorsal process that is slightly longer than body of element; presence of prominent lateral fossa on premaxilla anteroventral to external narial fenestra; premaxilla with five gently recurved, conical teeth; medial surface of maxilla with distinct ledge above the interdental plates; and maxilla and dentary with distinctly heterodont dentition. Phylogenetic analysis recovered Polymorphodon adorfi in a position crownward of Erythrosuchus africanus but in an unresolved polytomy with derived non-archosaurian archosauriforms such as Proterochampsidae and Euparkeria capensis and with Archosauria. The maxillary and dentary teeth of Polymorphodon adorfi differ from those of other non-archosaurian archosauriforms and indicate a different, possibly omnivorous diet, suggesting that these reptiles were more diverse in terms of feeding habits than previously assumed.
