description: In 2015, the U.S. poultry industry was impacted by an outbreak of avian influenza, resulting in fewer hens and increased egg prices. Various estimates of the economic costs of this outbreak have been reported in the extant literature; however, it is unclear how these estimates were derived. Therefore, in this study, we will estimate the economic impact, in terms of revenue loss, of the recent avian flu virus outbreak in the United States on the shell egg industry using established and cutting-edge econometric tools & methods. We estimated a vector autoregression (VAR) model using RATS and variables found in a wholesale egg price model from Chavez & Johnson’s paper in 1981. From this we generated forecast error decompositions and impulse response functions which provided insight into how the variables interact and their elasticity. The revenue impact of the 2015 avian influenza outbreak on wholesale producers will be estimated using the observed and counterfactual egg production and price change due to the hen depopulation. Once this is determined, losses will be translated to the farm and consumer level using elasticities. Preliminary results from forecast error decompositions show that variability in egg price is primarily due to itself, then egg production, hens, and soybean meal price. The impulse response functions indicate that egg price is inelastic, which is expected.

description: We present the details of a mean-field approximation scheme for the quantum mechanics of N D0-branes at finite temperature. The approximation can be applied at strong 't Hooft coupling. We find that the resulting entropy is in good agreement with the Bekenstein-Hawking entropy of a ten-dimensional non-extremal black hole with 0-brane charge. This result is in accord with the duality conjectured by Itzhaki, Maldacena, Sonnenschein and Yankielowicz. We study the spectrum of single-string excitations within the quantum mechanics, and find evidence for a clear separation between light and heavy degrees of freedom. We also present a way of identifying the black hole horizon.

On the Optimization of Broad-Band Photometry for Galaxy Evolution Studies

description: We have derived the uncertainties to be expected in the derivation of galaxy physical properties (star formation history, age, metallicity, reddening) when comparing broad-band photometry to the predictions of evolutionary synthesis models. We have obtained synthetic colors for a large sample (9000) of artificial galaxies assuming different star formation histories, ages, metallicities, reddening values, and redshifts. The colors derived have been perturbed by adopting different observing errors, and compared back to the evolutionary synthesis models grouped in different sets. The comparison has been performed using a combination of Monte Carlo simulations, a Maximum Likelihood Estimator and Principal Component Analysis. After comparing the input and derived output values we have been able to compute the uncertainties and covariant degeneracies between the galaxy physical properties as function of (1) the set of observables available, (2) the observing errors, and (3) the galaxy properties themselves. In this work we have considered different sets of observables, some of them including the standard Johnson/Cousins (UBVRI) and Sloan Digital Sky Survey (SDSS) bands in the optical, the 2 Micron All Sky Survey (2MASS) bands in the near-infrared, and the Galaxy Evolution Explorer (GALEX) bands in the UV, at three different redshifts, z=0.0, 0.7, and 1.4. This study is intended to represent a basic tool for the design of future projects on galaxy evolution, allowing an estimate of the optimal band-pass combinations and signal-to-noise ratios required for a given scientific objective.

description: Factors affecting stopover duration in birds are still much discussed. Field studies report contradictory evidence regarding the effect of fuel reserves on bird decision to depart from a stopover site, while the majority of laboratory tests performed on passerines reported a positive relationship between body conditions and migratory restlessness. In recent years, a few studies integrating laboratory and field investigations suggested that the amount of migratory restlessness could be a proxy of the individual willingness to depart from a stopover site in night-migrating passerines, but similar studies are lacking for other groups of birds. In this paper the factors affecting stopover length in the Wood sandpiper Tringa glareola (Charadriiformes Scolopacidae) were studied by integrating field observations and laboratory tests during spring migration. Our aims were to investigate (1) the influence of body conditions on migratory restlessness and (2) the influence of body conditions and of the amount of migratory restlessness on stopover duration, after controlling for meteorological conditions. Contrary to our expectations, we did not find any relationship between body condition and migratory restlessness nor stopover duration, while for the 1st time in a non-passerine species, evidence was produced that the amount of migratory restlessness is significantly related to the likelihood of leaving the stopover area. Our results emphasize the relevance of the studies integrating field and laboratory tests to understand the physiological and ecological factors affecting migratory behaviour in different bird species. Body conditions seem to be unrelated both to migratory restlessness and stopover duration. Migratory restlessness predicts the likelihood of leaving the stopover site. The quantification of migratory restlessness seems to be a useful tool for studying the effect of intrinsic and extrinsic factors on stopover behaviour in shorebirds.

description: In order to obtain information about the Standard Model from exclusive hadronic two-body B-decays, we have to quantify non-perturbative QCD effects. Approaches based on the factorization of mass singularities into hadronic distribution amplitudes and form factors provide a rigorous theoretical framework for the evaluation of these effects in the heavy quark limit. But it is not possible to calculate power corrections in a model-independent way, because of non-factorizing long-distance contributions. It has been argued that Sudakov effects suppress these contributions and render the corresponding corrections perturbatively calculable. In this paper we examine this claim for the related example of semileptonic B -> pi decays and conclude that it is not justified. The uncertainties in our knowledge of the mesons' distribution amplitudes imply that the calculations of the form factors are not sufficiently precise to be useful phenomenologically. Moreover, a significant contribution comes from the non-perturbative region of large impact parameters, and is therefore uncalculable. We also raise a number of theoretical issues in the derivation of the underlying formalism. For B-decays it is thus not possible to invoke Sudakov effects to calculate amplitudes for decays which have long-distance divergences (end-point singularities) in the standard hard-scattering approach.

description: Based on a model that incorporates brand entry deterrence through advertising and pricing strategies, this paper investigates whether firms’ advertising and pricing policies deviate from their short-run profit maximization strategies and how advertising and pricing entry deterrence strategies vary with market conditions. We estimate the advertising and pricing response of incumbents to entrants in four food industries: beer, carbonated soft drinks, ready-to-eat cereal and yogurt, and find that incumbents deviate significantly from profit maximization advertising and pricing policies. There is a U-shaped relationship between the potential market share of an entrant and incumbents’ pricing but an inverse U-shape with respect to advertising level. This means that incumbents are more likely to price higher and advertise less to deter entry when potential entrants are more competitive in terms of potential market share. Empirically, we show this to be the case in the four food industries studied.

description: We examine the accretion process in a thin disk surrounding a supermassive black hole within the framework of Einstein-Maxwell-scalar (EMS) gravity. Our investigation aims to elucidate how variations in model parameters affect different physical properties of the disk. When keeping EMS parameters $β$ and $q$ constant, we observe a reduction in radiation flux and temperature as $α$ increases. However, the luminosity and radiative efficiency exhibit relatively minor variation. Conversely, under fixed $α$ and $q$, an escalation in $β$ leads to heightened levels of radiation flux, temperature, luminosity, and radiative efficiency. These results underscore the diverse influences of model parameters on observable metrics, providing valuable insights for the astronomical study of distinct black holes.

description: In this paper, we define and apply representational stability analysis (ReStA), an intuitive way of analyzing neural language models. ReStA is a variant of the popular representational similarity analysis (RSA) in cognitive neuroscience. While RSA can be used to compare representations in models, model components, and human brains, ReStA compares instances of the same model, while systematically varying single model parameter. Using ReStA, we study four recent and successful neural language models, and evaluate how sensitive their internal representations are to the amount of prior context. Using RSA, we perform a systematic study of how similar the representational spaces in the first and second (or higher) layers of these models are to each other and to patterns of activation in the human brain. Our results reveal surprisingly strong differences between language models, and give insights into where the deep linguistic processing, that integrates information over multiple sentences, is happening in these models. The combination of ReStA and RSA on models and brains allows us to start addressing the important question of what kind of linguistic processes we can hope to observe in fMRI brain imaging data. In particular, our results suggest that the data on story reading from Wehbe et al. (2014) contains a signal of shallow linguistic processing, but show no evidence on the more interesting deep linguistic processing.

description: Despite encouraging developments in overall undernourishment figures our analysis of rural Cambodian households reveals very high malnutrition in children. In this paper we use a novel panel data set from Stung Treng in Cambodia which allows to compare different household food security indicators with each other and individual level anthropometric data of children under five. While the large majority of households appear to be food secure according to the Food Consumption Score (FCS) and the Household Hunger Scale (HHS), the Household Food Insecurity Access Scale (HFIAS) and the Coping Strategies Index (CSI) classify less than four percent of the households in Stung Treng as food secure. Stunting and underweight measures for children show that between 38 to 45 percent of children under five are classified as undernourished. Analyzing the influence of household characteristics on these different measures for food security we find that the FCS is largely driven by household characteristics and livelihood strategy choices whereas the anthropometrics show little or zero correlation. Household wealth, inequality, and the prevalence of shocks however, has a strong influence on both measures. Individual and mother specific characteristics are vital to explain child malnutrition.

description: Natural disasters are always associated with the disruption of local economies and hurting the local people. Households usually respond to those difficulties by cutting their consumption especially for non-necessity goods. Hence this paper discusses the pattern of food demand when the earthquake occurs. In addition, it also observes the price and expenditure elasticities of food demand by estimating a Linear Approximate Almost Ideal Demand System (LA-AIDS). This paper also examines the effect of earthquake on living standards of households. It finds that food demand estimations on rice and oil have price inelastic demand, while vegetable, meat, and fish are price elastic. Furthermore, poor households are more likely to have a greater negative impact than rich households although the effect is quite small.

description: Transaction cost economics posits that farmers opt to sell in a market that minimizes their costs of participation. Smallholder farmers in Nigeria face the choice of travelling to sell live chicken at the spot market or at the farm-gate. However, little is known of the factors that influence their choice. So far, studies on market choice overlook farmers lived experience in explaining their market decision. To investigate this gap in research, an explanatory sequential mixed methods design comprising a quantitative phase; followed by a qualitative phase is applied for the first time. We use a two-limit Tobit model to obtain quantitative results from a survey of 259 smallholder farmers in the first phase. Results show that: regular/repeat customers, bargaining power, access to extension services, access to credit, distance to the nearest township, stock size, bicycle ownership and price are factors that significantly influence the choice of selling at the farm-gate. In order to explore this finding in more depth, a qualitative phase was developed and 25 purposively selected respondents were interviewed. The overarching significance of this study is that by integrating quantitative and qualitative data substantially more information is obtainable than is usually obtainable from quantitative data alone.

 REMARKS: Two original spellings were used for the type species in Rondani (1859): frontalis (page 157) and frontosa (page 171). Herting (1984: 24), by indicating “ frontalis ” as a nomen nudum and adopting frontosa as an available name, is here interpreted as having acted as First Reviser and selected frontosa as the correct original spelling. Verrall in Scudder (1882: 164) listed the spelling Histochaeta and this was cited as an emendation by Bezzi & Stein (1907: 358, “ em. Verr. ap. Scudd. 1882”), but criteria for making this name available as an emendation were not found to be fulfilled in Scudder (1882). Histochaeta Verrall, 1882 is thus an unavailable name, new status. “ Histochaeta ” of Brauer & Bergenstamm (1891: 141; 1893: 105) and Bezzi & Stein (1907: 358) was based on a misidentification and used in the sense of Thelymorpha Brauer & Bergenstamm, 1889.

description: A choice experiment was carried out in Scotland to assess consumers’ preferences and willingness to pay (WTP) for four popular food attributes (i.e. animal welfare, organic, local and low fat attributes) and determine whether these attributes are independent, complement or substitutes. The results showed that the majority of consumers have positive preferences and are willing to pay a price premium for the four attributes. Furthermore, the results from the interactions between attributes showed that labelling organic pork as local could significantly increase its demand. The results also show that the co-existence of animal welfare and organic/local/low fat labels is likely to generate a discounting effect on consumers’ total premium for these bundles of food attributes (i.e. these attributes are perceived by consumers as overlapping). Organic and local attributes were found to be independent.

COMMENT
This species was not included in the monograph of the genus Riccia L. in the Mediterranean area by Jovet-Ast (1986), but was listed by Söderström et al. (2002, 2016), who mentioned knowledge problems. It was included in Hodgetts et al. (2020) as a species occurring in territories adjacent to Europe. According to Casares-Gil (1919) it is similar to Riccia macrocarpa Levier. Its identity remains doubtful.

description: A direct definition of the intrinsic magnetic moment of the electron is given, which does not use infrared regularizations and interactions with external fields. The expression does not depend on the unavoidable ambiguities of the definition of a 1-electron state (exact form of its soft photon cloud). The method leads to the same analytic expression as the conventional approach, thus preserving the excellent agreement between theory and experiment.

description: This paper introduces a nonparametric measure of coordination Luenberger productivity growth where the subprocesses are explicitly modelled in the production technology. The coordination productivity indicator is decomposed into a coordination technical inefficiency change component and a coordination technical change component. This decomposition allows to assess how reallocation impacts the different sources of productivity growth. The empirical application focusses on a large panel of English and Welsh farms over the period 2007−2013. The results show that coordination inefficiency significantly increases with the proportion of resources allocated to livestock production in economic and statistical terms. Coordination inefficient farms should generally allocate more land to crop production. Depending on the region, the average coordination Luenberger productivity growth ranges from -9.7 percent to 15.9 percent per year. It is driven by coordination technical change rather than coordination inefficiency change.
Entanglement required in achieving entanglement-assisted channel capacities

Subjects: subject: Quantum Physics (quant-ph)

description: Entanglement shared between the two ends of a quantum communication channel has been shown to be a useful resource in increasing both the quantum and classical capacities for these channels. The entanglement-assisted capacities were derived assuming an unlimited amount of shared entanglement per channel use. In this paper, bounds are derived on the minimum amount of entanglement required per use of a channel, in order to asymptotically achieve the capacity. This is achieved by introducing a class of entanglement-assisted quantum codes. Codes for classes of qubit channels are shown to achieve the quantum entanglement-assisted channel capacity when an amount of shared entanglement per channel given by, E = 1 - Q_E, is provided. It is also shown that for very noisy channels, as the capacities become small, the amount of required entanglement converges for the classical and quantum capacities.

description: It is imperative that robots can understand natural language commands issued by humans. Such commands typically contain verbs that signify what action should be performed on a given object and that are applicable to many objects. We propose a method for generalizing manipulation skills to novel objects using verbs. Our method learns a probabilistic classifier that determines whether a given object trajectory can be described by a specific verb. We show that this classifier accurately generalizes to novel object categories with an average accuracy of 76.69% across 13 object categories and 14 verbs. We then perform policy search over the object kinematics to find an object trajectory that maximizes classifier prediction for a given verb. Our method allows a robot to generate a trajectory for a novel object based on a verb, which can then be used as input to a motion planner. We show that our model can generate trajectories that are usable for executing five verb commands applied to novel instances of two different object categories on a real robot.

 REMARKS: Although Herting & Dely-Draskovits (1993: 345) gave the method of type fixation for Istoglossa in Rondani (1856: 77) as by original designation, they listed the type species as dating from Rondani (1861e: 104). This is incorrect. The characters in Rondani (1856: 77) that make the genus-group name available serve to also make available Istoglossa puella as the singly included species. Verrall in Scudder (1882: 164) listed the spelling Histoglossa and this was cited as an emendation by Bezzi & Stein (1907: 393, “ em.

description: Power Density Spectrum (PDS) is one of the powerful tools to study light curves of gamma-ray bursts (GRBs). We show the average PDS and individual PDS analysis with {\it Hard X-ray Modulation Telescope} (also named \insighthxmt) GRBs data. The values of power-law index of average PDS ($α_{\bar{P}}$) for long GRBs (LGRBs) vary from 1.58-1.29 (for 100-245, 245-600, and 600-2000 keV). The \insighthxmt\ data allow us to extend the energy of the LGRBs up to 2000 keV, and a relation between $α_{\bar{P}}$ and energy $E$, $α_{\bar{P}}\propto E^{-0.09}$ (8-2000 keV) is obtained. We first systematically investigate the average PDS and individual PDS for short GRBs (SGRBs), and obtain $α_{\bar{P}}\propto E^{-0.07}$ (8-1000 keV), where the values of $α_{\bar{P}}$ vary from 1.86 to 1.34. The distribution of power-law index of individual PDS ($α$) of SGRB, is consistent with that of LGRB, and the $α$ value for the dominant timescale group (the bent power-law, BPL) is higher than that for the no-dominant timescale group (the single power-law, PL). Both LGRBs and SGRBs show similar $α$ and $α_{\bar{P}}$, which indicates that they may be the result of similar stochastic processes. The typical value of dominant timescale $τ$ for LGRBs and SGRBs is 1.58 s and 0.02 s, respectively. It seems that the $τ$ in proportion to the duration of GRBs $T_{90}$, with a relation $τ\propto T_{90}^{0.86}$. The GRB light curve may result from superposing a number of pulses with different timescales. No periodic and quasi-periodical signal above the 3$σ$ significance threshold is found in our sample.

description: Real agricultural income in the EU is estimated to have fallen by 4.0% in 2015 relative to 2014, while agricultural labour input dropped by 1.8%, thus income per worker decreased by 2.1%. The value of agricultural output in 2015 decreased by 3.0% in real terms, mainly due to a marked fall in the value of animal production, a slight decrease in the value of crop production, and a moderate decrease for input costs. The fall for animal production is mainly due to declines for milk and pigs, partly compensated by increases for cattle, sheep and goats, eggs and poultry. Concerning crop production, falls for sugar beet, grain maize, forage plants, oilseeds and oleaginous fruits, barley, and wheat and spelt, were almost counterbalanced by rises for olive oil, fresh vegetables, fruits and wine. The drop in the value of sugar beet and maize was associated with the summer drought in certain Member States. Input costs decreased by 3.5%, mainly due to reductions for energy and lubricants, and animal feed. The fall in the price of feed is a reflection of the decrease in the producer price of several cereals. These data are based on a revised set of estimates published by Eurostat in March 2016.

description: The magnetic compass of birds seems to be based on light-dependent radical-pair processes in the eyes. Cryptochromes are currently the only candidate proteins known in vertebrates that may serve as the primary radical-pair-based magnetoreceptor molecules. Previous immunohistochemical studies have suggested that cryptochrome 1a (Cry1a) is localised in the photoreceptor outer segments of the ultraviolet/violet (UV/V) cones, and it has been claimed that differences in Cry1a antibody staining intensities show that Cry1a is activated by light and that this should make Cry1a the most likely magnetoreceptive candidate molecule. Here, we present an independent study of Cry1a distribution within retinae of several bird species, ranging from non-migratory domestic chicken and rock pigeon to night-migratory passerines, using both the previously used antibody and two newly generated antibodies, one against the same epitope as the originally used antibody and one against a different epitope of Cry1a. We confirm the UV/V cone outer segment localisation of Cry1a in all the tested bird species. In some stainings, we found Cry1a immunoreactivity as a distinct punctate pattern throughout the whole length of the UV/V cone outer segments. These dots with a diameter of around 170 nm might suggest that many Cry1a molecules accumulate in distinct spots in the UV/V cone outer segments. However, we did not see any notable difference in Cry1a immunoreactivity between light- and dark-adapted retinae. We find no evidence whatsoever that a C-terminal antibody against Cry1a labels only a light-activated form of the Cry1a protein.
Symmetry Breaking for Matter Coupled to Linearized Supergravity From the Perspective of the Current Supermultiplet
Creators: name: Adler, Stephen L.

Year: 2001
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider a generic supersymmetric matter theory coupled to linearized supergravity, and analyze scenarios for spontaneous symmetry breaking in terms of vacuum expectation values of components of the current supermultiplet. When the vacuum expectation of the energy momentum tensor is zero, but the scalar current or pseudoscalar current gets an expectation, evaluation of the gravitino self energy using the supersymmetry current algebra shows that there is an induced gravitino mass term. The structure of this term generalizes the supergravity action with cosmological constant to theories with CP violation. When the vacuum expectation of the energy momentum tensor is nonzero, supersymmetry is broken; requiring cancellation of the cosmological constant gives the corresponding generalized gravitino mass formula.

Determination of stellar parameters with GAIA

Subjects: subject: Astrophysics (astro-ph)

description: The GAIA Galactic survey satellite will obtain photometry in 15 filters of over 10^9 stars in our Galaxy across a very wide range of stellar types. No other planned survey will provide so much photometric information on so many stars. I examine the problem of how to determine fundamental physical parameters (Teff, log g, [Fe/H] etc.) from these data. Given the size, multidimensionality and diversity of this dataset, this is a challenging task beyond any encountered so far in large-scale stellar parametrization. I describe the problems faced (initial object identification, interstellar extinction, multiplicity, missing data etc.) and present a framework in which they can can be addressed. A probabilistic approach is advocated on the grounds that it can take advantage of additional information (e.g. priors and data uncertainties) in a consistent and useful manner, as well as give meaningful results in the presence of poor or degenerate data. Furthermore, I suggest an approach to parametrization which can use the other information GAIA will acquire, in particular the parallax, which has not previously been available for large-scale multidimensional parametrization. Several of the problems identified and ideas suggested will be relevant to other large surveys, such as SDSS, DIVA, FAME, VISTA and LSST, as well as stellar parametrization in a virtual observatory.

Constraint supersymmetry Breaking and Non-perturbative Effects in String Theory

description: We discuss supersymmetry breaking mechanisms at the level of low energy N=1 effective heterotic superstring actions that exhibit $SL(2,Z)_T$ target space modular duality or $SL(2,Z)_S$ strong-weak coupling duality. The allowed superpotential forms use the assumption that the source of non-perturbative effects is not specified and as a result represent the most general parametrization of non-perturbative effects. The minimum values of the limits on the parameters in the superpotential may correspond to vacua with vanishing cosmological constant.

description: In order to better blend green plum wine and study aromatic components of green plum wine, a qualitative analysis on aromatic components of soaked base liquor, green plum soaked wine, green plum juice, and fermented wine of green plum juice by Head Space Solid-phase Microextraction (HS-SPME) and Gas Chromatograph Mass Spectrometer (GC-MS) was studied in this paper. Experiment results indicated that 14，32，17，and 46 kinds of aromatic components were identified respectively from four samples. Different aromatic components determined the special flavor and taste of green plum wine. Unique aromatic components generated in soaking process include benzaldehyde, 1-butanol, 2-methyl-, S-(-), benzoic acid ethyl ester, and 5-(hydroxymethyl). Special aromatic components in green plum juice were furfural, phenylethyl alcohol, and benzyl alcohol. The aromatic components in fermented wine of green plum juice mainly included phenylethyl alcohol (6.941%, relative content of peak area, same below), 1-butanol, 3-methyl- (6.940%), octanoic acid, ethyl ester (3.734%), decanoic acid, ethyl ester (2.590%), hexanoic acid, ethyl ester (2.479%), ethyl 9-decenoate (2.080%), and 5-hydroxymethyl (1.756%). This study was expected to provide scientific basis and data reference for quality improvement of green plum wine.

description: The long-range dipole-dipole interaction can create delocalized states due to the exchange of excitation between Rydberg atoms. We show that even in a random gas many of the single-exciton eigenstates are surprisingly delocalized, composed of roughly one quarter of the participating atoms. We identify two different types of eigenstates: one which stems from strongly-interacting clusters, resulting in localized states, and one which extends over large delocalized networks of atoms. These two types of states can be excited and distinguished by appropriately tuned microwave pulses, and their relative contributions can be modified by the Rydberg blockade and the choice of microwave parameters.
