description: If a supernova explosion occurs within a few hundred parsecs from the Earth, a huge number of axions, in addition to neutrinos, may arrive at the Earth. In this paper, we discuss in detail the prospect of detecting those supernova axions by an axion helioscope. With the help of a pre-supernova neutrino alert system, it is possible to point a helioscope at an exploding supernova in advance. The supernova axions can then be detected by a gamma-ray detector installed at the end of the helioscope. We call such a detection system an axion supernova-scope (SNscope). We propose a conceptual design for an axion SNscope, where the gamma-ray detector is installed at the opposite end to the X-ray detector for the solar axion. It still functions as an axion helioscope during the normal operation time, and once a pre-SN neutrino alert is received, the scope is temporarily turned around and targeted to a SN candidate, waiting for the supernova axions. We estimate the sensitivity of supernova axion detection and find that SNscopes based on the next-generation axion helioscopes, such as IAXO, have potential to explore the invisible axions and to test the axion interpretation of stellar cooling anomalies.

description: Diversification of consumers’ demand and environmental concerns are at the origin of a trend towards short marketing chains and towards direct links between consumers and farmers in developed countries. This paper explores farmers’ motivations for choosing these types of marketing chains and/or the “traditional” ones. To this purpose, a theoretical model of marketing chain choice is developed, and a multivariate probit model of organic farmers’ choice of the marketing chain is estimated from a unique data set of organic farms in an Italian region.
Prevalence of exercise-induced arterial hyposemia in female asthmatic athletes
Creators: name: Lynn, Brenna Meaghan
Publisher: name: University of British Columbia
Year: 2009

description: It has been suggested that habitual exercise training may cause mechanically or chemically mediated endothelial dysfunction during heavy exercise, which may lead to exercise-induced arterial hypoxemia. Cellular adhesion molecules E- and P-selectin have been used as direct markers of endothelial injury. Elevated plasma levels of these inflammatory mediators along with IL-6 have been present in acute lung injury and also after intense exercise. To determine whether asthmatic female athletes have higher incidence of exercise-induced arterial hypoxemia (EIAH) and higher plasma levels of soluble P-selectin and IL-6 when compared to controls, 16 female asthmatics (age = 26.4 ± 5.7 yrs; ht = 165.7 ± 7.6 cm; wt = 61.7 ± 10.9 kg; VO[sub 2max]= 46.8 ± 8.0 mL•kg⁻¹•min⁻¹, range 29.3 to 57.3 mL•kg⁻¹•min⁻¹) and 16 female non-asthmatic athletes (age = 26.2 ± 4.2 yrs; ht = 167.2 ± 6.8 cm; wt = 57.5 ± 6.0 kg; VO[sub 2max]= 51.9 ± 8.2 mL•kg⁻¹•min⁻¹, range 40.0 to 67.9 mL•kg⁻¹•min⁻¹) were tested during the mid-follicular phase of their menstrual cycle. Subjects completed an incremental maximal treadmill test on the first day of testing. Exercise-induced arterial hypoxemia (%SaO₂ ≤ 93%) was seen in 7 of the 16 asthmatics and 8 of the 16 control subjects. On day 2 during the run to exhaustion test, 6 of 16 asthmatics decreased %SaO₂ to less than 93%, whereas 9 of the 16 controls developed EIAH. The data failed to show significance (p >0.05) in %SaO₂ between groups on Day 1 (p = 0.74) and Day 2 (p = 0.93). There was a significant decrease in saturation over time for both groups (p = 0.00 and p = 0.00). P-selectin and IL-6 were . measured on Day 2 by enzyme immunoassay before and after the treadmill run to exhaution test. With exercise, there was a significant change over time for both Pselectin (p = 0.00) and IL-6 (p = 0.00). No significant group by time interaction was seen in pre-post concentration of P-selectin (p = 0.37) or IL-6 (p = 0.43). There was however a significant difference in pre-post concentration of IL-6 (p = 0.04) between those controls that displayed EIAH and those that did not develop EIAH. No significance was seen in asthmatics with respect to IL-6 and EIAH. Plasma concentrations of soluble Pselectin (p = 0.94) and IL-6 (p = 0.27) were not significantly different between groups. No statistical significance was apparent in P-selectin and hypoxemia between groups. The incidence of EIAH in an asthmatic population is not significantly higher in asthmatics when compared to controls. The increased levels in plasma P-selectin and IL- 6 after intense exercise may represent endothelial dysfunction. However, increased plasma level of P-selectin and IL-6 were seen in both groups and therefore cannot support the hypothesis that asthmatics show increased levels of inflammatory markers due to lung damage from chronic-recurrent high stresses of breathing during exercise training.

description: We consider a class of 6D superconformal field theories (SCFTs) which have a large $N$ limit and a semi-classical gravity dual description. Using the quiver-like structure of 6D SCFTs we study a subsector of operators protected from large operator mixing. These operators are characterized by degrees of freedom in a one-dimensional spin chain, and the associated states are generically highly entangled. This provides a concrete realization of qubit-like states in a strongly coupled quantum field theory. Renormalization group flows triggered by deformations of 6D UV fixed points translate to specific deformations of these one-dimensional spin chains. We also present a conjectural spin chain Hamiltonian which tracks the evolution of these states as a function of renormalization group flow, and study qubit manipulation in this setting. Similar considerations hold for theories without $AdS$ duals, such as 6D little string theories and 4D SCFTs obtained from compactification of the partial tensor branch theory on a $T^2$.

description: This essay examines the relationship between stand-up comedy and identity representation. The methods for examination begin with an overview of relevant humour theories, culminating in a case study of comedian Vir Das’s role in cultivating a collective secular identity in India. The case study takes on the method of critical textual analysis. By contextualizing the content of Vir Das’s 2018 Netflix stand-up special, Losing It, in relation to the historical and present landscape of religio-politics in India, I argue that stand-up routines like Vir Das’s represent humour being used as a tool to promote secularism and religious tolerance. I then conclude by suggesting that the use of this type of humour in India should continue in order to foster an Indian collective identity that promotes secularism, religious freedom, and religious tolerance. Unexpectedly, I also conclude that Vir Das’s religious-themed humour takes on a more tolerant, encompassing approach to mocking religious hegemony, compared to Western comedy approaches.

description: The pursuit of higher education among single mother nurses working in foreign countries presents unique challenges that intertwine professional, academic, and caregiving responsibilities. This study aimed to explore and document the struggles faced by single mothers in the nursing profession as they pursue graduate education abroad. Utilizing a qualitative-descriptive research design, purposive sampling was employed to select 15 participants from various countries. Data were collected through semi-structured interviews guided by an interview protocol and analyzed using thematic analysis. Eight major themes emerged from the data: financial constraints, time management challenges, lack of social support, emotional and mental health issues, institutional barriers, work-study-life balance, motivational factors, and coping strategies. The findings highlighted the significant financial and emotional burdens experienced by single mother nurses, exacerbated by inadequate institutional support and the demanding nature of both their work and academic environments. Despite these challenges, participants demonstrated remarkable resilience and determination to achieve their educational goals. The study underscores the need for more flexible academic programs, enhanced institutional support, and targeted policies to assist single mother nurses in balancing their multiple roles. Recommendations include the development of comprehensive support systems within educational institutions and workplaces to better accommodate the unique needs of this demographic. This research contributes to the limited literature on single mother nurses in higher education and provides actionable insights for policymakers and educational institutions.

description: This paper develops a structural econometric model of agricultural land use and production based on the joint multi-output technology representation introduced by Chambers and Just (1989). Starting from a flexible specification of the farm profit function we derive land use allocation, input applications, crops yield and livestock number equations in a joint and theoretically consistent framework. We present an empirical application using fine-scale spatial data covering the entirety of England and Wales and including the main economic, policy and environmental drivers of land use change in the past 40 years. To account for the presence of censored observations in this micro-level data we estimate the model as a system of two-limits Tobit equations via Quasi-Maximum Likelihood. We finally compare the forecasting ability of our approach against an established benchmark: the land use share logit model.

description: Chemical transformation of existing two-dimensional (2D) materials can be crucial in further expanding the 2D crystal palette required to realize various functional heterostructures. In this work, we demonstrate a 2D 'on-stack' chemical conversion of single-layer crystalline MoS2 into MoO3 with a precise layer control that enables truly 2D MoO3 and MoO3/MoS2 heterostructures. To minimize perturbation of the 2D morphology, a nonthermal oxidation using O2 plasma was employed. The early stage of the reaction was characterized by a defect-induced Raman peak, drastic quenching of photoluminescence (PL) signals and sub-nm protrusions in atomic force microscopy images. As the reaction proceeded from the uppermost layer to the buried layers, PL and optical second harmonic generation signals showed characteristic modulations revealing a layer-by-layer conversion. The plasma-generated 2D oxides, confirmed as MoO3 by x-ray photoelectron spectroscopy, were found to be amorphous but extremely flat with a surface roughness of 0.18 nm, comparable to that of 1L MoS2. The rate of oxidation quantified by Raman spectroscopy decreased very rapidly for buried sulfide layers due to protection by the surface 2D oxides, exhibiting a pseudo-self-limiting behavior. As exemplified in this work, various on-stack chemical transformations can be applied to other 2D materials in forming otherwise unobtainable materials and complex heterostructures, thus expanding the palette of 2D material building blocks.

The OPE for the correlation function with N^4LO, O(alpha_s^4) accuracy in the perturbative part, and with dimension <= 6 operators reveals a good convergence. We observe a significant improvement of stability of the sum rule with respect to the variation of the renormalization scale after including the O(alpha_s^4) correction. We obtain the interval m_s(2 GeV)=105 \pm 6 \pm 7 MeV, which exhibits about 2 MeV increase of the central value, if the O(alpha_s^4) terms are removed.

description: Context: Programmers frequently look for the code of previously solved problems that they can adapt for their own problem. Despite existing example code on the web, on sites like Stack Overflow, cryptographic Application Programming Interfaces (APIs) are co monly misused. There is little known about what makes examples helpful for developers in using crypto APIs. Analogical problem solving is a psychological theory that investigates how people use known solutions to solve new problems. There is evidence that the capacity to reason and solve novel problems a.k.a Fluid Intelligence (Gf ) and structurally and procedurally similar solutions support problem solving. Aim: Our goal is to understand whether similarity and Gf also have an effect in the context of using cryptographic APIs with the help of code examples. Method: We conducted a controlled experiment with 76 student participants developing with or without procedurally similar examples, one of two Java crypto libraries and measured the Gf of the participants as well as the effect on usability (effectiveness, efficiency, satisfaction) and security bugs. Results: We observed a strong effect of code examples with a high procedural similarity on all dependent variables. Fluid intelligence Gf had no effect. It also made no difference which library the participants used. Conclusions: Example code must be more highly similar to a concrete solution, not very abstract and generic to have a positive effect in a development task.

description: A majority of UK dairy herds have the potential to increase profitability by improving the ration of their cows. This paper reports that gains averaging around £100 per cow have been made within one year of adopting the Keenan Hi-Fibre ration by 239 UK herds in 2006 and 2007. Larger gains have been made by herds in France. The key performance indicator underlying these gains is Feed Conversion Efficiency, whereby the same, or even a smaller amount of Dry Matter Intake generates higher yields per cow. Importantly, the gains are associated with large improvements in animal health and reductions in greenhouse gases per litre of milk produced.

description: Blockchain Technology has revolutionized Finance and Technology with its secure, decentralized, and trust-less methodologies of data management. In a world where asset value fluctuations are unprecedented, it has become increasingly important to secure one's stake on their valuable assets and streamline the process of acquiring and transferring that stake over a trust-less environment. Tokenization proves to be unbeaten when it comes to giving the ownership of one's asset, an immutable, liquid, and irrefutable identity, as of the likes of cryptocurrency. It enables users to store and maintain records of their assets and even transfer fractions of these assets to other investors and stakeholders in the form of these tokens. However, like cryptocurrency, it too has witnessed attacks by malicious users that have compromised on their very foundation of security.These attacks have inflicted more damage since they represent real-world assets that have physical importance. This project aims to assist users to secure their valuable assets by providing a highly secure user-friendly platform to manage, create and deploy asset-tokens, and facilitate open and transparent communication between stakeholders, thereby upholding the decentralized nature of blockchain and offering the financial freedom of asset ownership, with an added market value of a cryptocurrency-backed tokens.

description: In this paper, we evaluate the role of market power by retailers within the supply chain of Parmigiano Reggiano and Grana Padano, the two most famous Italian quality cheeses. Market power is analysed in the context of an imperfect competition model of the supply chain, in which retailers are allowed to exercise market power both downstream and upstream. We jointly estimate market power parameters together with supply and demand elasticities, by means of a structural system of demand, supply and price transmission equations, estimated using the Generalised Method of Moments. We find clear evidences of downstream market power by retailers (toward final consumers), and no evidences of upstream market power (toward processors/ripeners). These results may be justified by the structure of the supply chain and by the peculiar characteristics of the two cheeses.

description: Le Prince de Machiavel, l’un des ouvrages centraux de la réflexion sur le politique en Europe, a été achevé en 1513. Cinq siècles après, ce texte qui transgresse les normes convenues du discours interpelle toujours le lecteur. Comment la philosophie politique d’aujourd’hui se situe-t-elle par rapport à ce document fondateur ? Afin de commémorer cette date importante pour la formation de la pensée sur l’état et le pouvoir, le philosophe et député européen Leonidas Donskis a réuni des articles consacrés aux notions cruciales de Machiavel. Ce recueil invite à réfléchir sur la portée actuelle de l’approche machiavélienne. Machiavelli’s Prince was finished in 1513. It remains one of the most important texts related to political thought. Written five hundred years ago, this work still invites the reader to reflect on politics and human behaviour. How does political philosophy value this document today? In order to give answers to this question, the philosopher and Member of the European Parliament Leonidas Donskis has edited an essay collection which deals with the key notions of Machiavellian thought. These scientific essays give a hint about the actual scope of Machiavelli’s approach.

description: Systemic weather risk is a major obstacle for the formation of private (nonsubsidized) crop insurance. This paper explores the possibility of spatial diversification of insurance by estimating the joint occurrence of unfavorable weather conditions in different locations. For that purpose copula methods are employed that allow an adequate description of stochastic dependencies between multivariate random variables. The estimation procedure is applied to weather data in Germany. Our results indicate that indemnity payments based on temperature as well as on cumulative rainfall show strong stochastic dependence even at a national scale. Thus the possibility to reduce risk exposure by increasing the trading area of the insurance is limited. Irrespective of their economic implications our results pinpoint the necessity of a proper statistical modeling of the dependence structure of multivariate random variables. The usual approach of measuring stochastic dependence with linear correlation coefficients turned out to be questionable in the context of weather insurance as it may overestimate diversification effects considerably.
Superfluid vortex-mediated mutual friction in non-homogeneous neutron star interiors

description: Understanding the average motion of a multitude of superfluid vortices in the interior of a neutron star is a key ingredient for most theories of pulsar glitches. In this paper we propose a kinetic approach to compute the mutual friction force that is responsible for the momentum exchange between the normal and superfluid components in a neutron star, where the mutual friction is extracted from a suitable average over the motion of many vortex lines. As a first step towards a better modelling of the repinning and depinning processes of many vortex lines in a neutron star, we consider here only straight and non-interacting vortices: we adopt a minimal model for the dynamics of an ensemble of point vortices in two dimensions immersed in a non-homogeneous medium that acts as a pinning landscape. Since the degree of disorder in the inner crust or outer core of a neutron star is unknown, we compare the two possible scenarios of periodic and disordered pinscapes. This approach allows to extract the mutual friction between the superfluid and the normal component in the star when, in addition to the usual Magnus and drag forces acting on vortex lines, also a pinning force is at work. The effect of disorder on the depinning transition is also discussed.

description: The potential supply of biomass feedstocks in the US and Canada is estimated using a static supply function approach. Estimated total biomass available at a price of $100 per metric ton is 568 million metric tons in the US and 123 million tons in Canada, which together can displace 23-45 billion gallons of gasoline. Sufficient biomass, mainly agricultural and mill residues, will be available at prices of around $50/ton to meet the advanced biofuel mandates of the US Energy Independence and Security Act of 2007. The estimates of agricultural residue supply are very sensitive to the assumed fraction of residues that can be sustainably removed from the field, and the potential of municipal solid waste as a feedstock depends on which components can be economically converted into liquid biofuels.

description: The coherent manipulation of acoustic waves on the nanoscale usually requires multilayers with thicknesses and interface roughness defined down to the atomic monolayer. This results in expensive devices with predetermined functionality. Nanoscale mesoporous materials present high surface-to-volume ratio and tailorable mesopores, which allow the incorporation of chemical functionalization to nanoacoustics. However, the presence of pores with sizes comparable to the acoustic wavelength is intuitively perceived as a major roadblock in nanoacoustics. Here we present multilayered nanoacoustic resonators based on mesoporous SiO$_2$ thin-films showing acoustic resonances in the 5-100 GHz range. We characterize the acoustic response of the system using coherent phonon generation experiments. Despite resonance wavelengths comparable to the pore size, we observe for the first time unexpectedly well-defined acoustic resonances with Q-factors around 10. Our results open the path to a promising platform for nanoacoustic sensing and reconfigurable acoustic nanodevices based on soft, inexpensive fabrication methods.

description: We survey the geometry of Lagrange and Finsler spaces and discuss the issues related to the definition of curvature of nonholonomic manifolds enabled with nonlinear connection structure. It is proved that any commutative Riemannian geometry (in general, any Riemann--Cartan space) defined by a generic off--diagonal metric structure (with an additional affine connection possessing nontrivial torsion) is equivalent to a generalized Lagrange, or Finsler, geometry modeled on nonholonomic manifolds. This results in the problem of constructing noncommutative geometries with local anisotropy, in particular, related to geometrization of classical and quantum mechanical and field theories, even if we restrict our considerations only to commutative and noncommutative Riemannian spaces. We elaborate a geometric approach to the Clifford modules adapted to nonlinear connections, to the theory of spinors and the Dirac operators on nonholonomic spaces and consider possible generalizations to noncommutative geometry. We argue that any commutative Riemann--Finsler geometry and generalizations my be derived from noncommutative geometry by applying certain methods elaborated for Riemannian spaces but extended to nonholonomic frame transforms and manifolds provided with nonlinear connection structure.

description: We investigate an extension of the Minimal Standard Model by right-handed neutrinos (the $ν$MSM) to incorporate neutrino masses consistent with oscillation experiments. Within this theory, the only candidates for dark matter particles are sterile right-handed neutrinos with masses of a few keV. Requiring that these neutrinos explain entirely the (warm) dark matter, we find that their number is at least three. We show that, in the minimal choice of three sterile neutrinos, the mass of the lightest active neutrino is smaller than ${\cal O}(10^{-5})$ eV, which excludes the degenerate mass spectra of three active neutrinos and fixes the absolute mass scale of the other two active neutrinos.

description: Model of biological effects of ionizing particles, especially of protons and other ions, is proposed. The model is based on distinguishing the single-particle and collective effects of the underlying radiobiological mechanism. The probabilities of individual particles to form severe damages to DNA, their synergetic or saturation combinations, and the effect of cellular repair system are taken into account. The model enables to describe linear, parabolic and more complex curves, including those exhibiting low-dose hypersensitivity phenomena, in a systematic way. Global shape as well as detailed structure of survival curves might be represented, which is crucial if different fractionation schemes in radiotherapy should be assessed precisely. Experimental cell-survival data for inactivation of V79 cells by low-energy protons have been analyzed and corresponding detailed characteristics of the inactivation mechanism have been derived for this case.

description: The paper analyses how the rising agricultural prices affect heterogenous farm access to inputs and production under credit market imperfections in the CEE transition countries. Using farm level panel data which contains 37416 observations, we estimate a farm credit constraint equation and find that small individual farms (IF) are on average more credit constrained than large corporate farms (CF). Using the estimated parameters we simulate the effect of the recent food price shock. Our results suggest that in the presence of credit market imperfections, the relatively less credit constrained CF benefit more from higher output prices than IF, as they are able to expand their production more flexibly. These findings have implications for the developing countries: not only consumers in the LDC may loose, but also producers, which on average are more credit constrained than farmers in developed countries, may loose their market shares and hence income in the log run.

description: Designing deep neural networks is an art that often involves an expensive search over candidate architectures. To overcome this for recurrent neural nets (RNNs), we establish a connection between the hidden state dynamics in an RNN and gradient descent (GD). We then integrate momentum into this framework and propose a new family of RNNs, called {\em MomentumRNNs}. We theoretically prove and numerically demonstrate that MomentumRNNs alleviate the vanishing gradient issue in training RNNs. We study the momentum long-short term memory (MomentumLSTM) and verify its advantages in convergence speed and accuracy over its LSTM counterpart across a variety of benchmarks. We also demonstrate that MomentumRNN is applicable to many types of recurrent cells, including those in the state-of-the-art orthogonal RNNs. Finally, we show that other advanced momentum-based optimization methods, such as Adam and Nesterov accelerated gradients with a restart, can be easily incorporated into the MomentumRNN framework for designing new recurrent cells with even better performance. The code is available at https://github.com/minhtannguyen/MomentumRNN.

Improving the understanding of the melting behaviour of Mo, Ta, and W at extreme pressures

description: We discus existent conflicts between experimentally measured and theoretically calculated melting curves of Mo, Ta, and W. By assuming that vacancy formation plays a fundamental role in the melting process, an explanation for the measured melting curves is provided. Furthermore, we show that the Lindemann law fits well all the measured melting curves of bcc transition metals if the Grueneisen parameter is written as a power series of the interatomic distance. For completeness, we examine possible reasons for current disagreements between shock-wave and DAC experiments. To solve them, we propose the existence of an extra high P-T phase for Mo, Ta, and W

description: Higher order curvature gravity has recently received a lot of attention due to the fact that it gives rise to cosmological models which seem capable of solving dark energy and quintessence issues without using "ad hoc" scalar fields. Such an approach is naturally related to fundamental theories of quantum gravity which predict higher order terms for loop expansions of quantum fields in curved spacetimes. In this framework, we obtain a class of cosmological solutions which are fitted against cosmological data. We reproduce reliable models able to fit high redshift supernovae and WMAP observations. The age of the universe and other cosmological parameters are recovered in this context. Furthermore, in the weak field limit, we obtain gravitational potentials which differ from the Newtonian one because of repulsive corrections increasing with distance. We evaluate the rotation curve of our Galaxy and compare it with the observed data in order to test the viability of these theories and to estimate the scale-length of the correction. It is remarkable that the Milky Way rotation curve is well fitted without the need of any dark matter halo and similar results hold also for other galaxies.

description: In this paper we study the determinants of the factor content of the CEE agricultural trade. Examining empirically three hypothesis, which relate cross-country differences in technology, relative factor abundance and transaction costs and market imperfections to the factor content of trade, we find that the first two hypotheses are confirmed by the majority of the developed EU countries, but rejected by roughly one half of the CEE transition country pairs. Second, we find that when accounting for transaction costs of farm (re)organisation, both hypotheses are confirmed by the majority of the CEE country pairs. These findings provide empirical evidence of market imperfections, and particularly, of transaction costs of farm (re)organisation in the CEE.
