Subjects: subject: General Economics (econ.GN)
subject: FOS: Economics and business

description: The aim of this study is to contribute to the theory of exogenous economic shocks and their equivalents in an attempt to explain business cycle fluctuations, which still do not have a clear explanation. To this end the author has developed an econometric model based on a regression analysis. Another objective is to tackle the issue of hybrid threats, which have not yet been subjected to a cross-disciplinary research. These were reviewed in terms of their economic characteristics in order to complement research in the fields of defence and security.

Remarks. Manouria emys occupies a wide, native distribution ranging from Bangladesh and India, east through Myanmar, Thailand, Peninsular Malaysia, Sumatra, and Borneo (TTWG 2021). Given this distribution, it has been suspected that M. emys occurred naturally in Singapore, and is even listed as extirpated (Stanford et al. 2015; TTWG 2021). Gray (1854) mistakenly listed Singapore as the locality of a specimen collected in Penang (Gray 1855). As no historical specimens exist for M. emys from Singapore, we exclude it from Singapore’s herpetofauna checklist. Nonetheless, released individuals have been sighted at BTNR on 5 January 1989 (Lim 1989), NSSF in June 2002 (K.W. Li pers. comm.), 9 June 2011 (Y. Cai pers. comm.), and on 29 January 2014 (Pai & Tan 2014), and UP on 12 May 2014 (W. Ng pers. comm.).

description: Consumers are increasingly interested in the impacts of agricultural production on the environment, animals, workers, health etc – all examples of credence attributes. While governments set and enforce minimum requirements regarding these attributes, roles for government in markets for products with additional levels of these attributes (‘ecolabelled’ products) are less clearly defined and understood. This presents a risk that government actions will create distortions in markets for ecolabelled and non-ecolabelled products. This is especially likely if policy is based on pursuing environmental and other outcomes through encouraging ecolabelling. There are some areas, it is argued, where government actions could increase the efficiency of markets for goods with additional credence qualities. This is because of the impacts of information asymmetries between producers and consumers. However, firms have developed many ways to signal the credibility of their claims, and any government intervention must be cognisant of this. The paper reports on a continuing body of work within the Victorian Department of Primary Industries aimed at identifying roles for government in ecolabelling, and progressing their implementation.

description: We discuss whether the future extrapolation of the present cosmological state may lead to a singularity even in case of "conventional" (negative) pressure of the dark energy field, namely $w=p/ρ\geq -1$. The discussion is based on an often neglected aspect of scalar-tensor models of gravity: the fact that different test particles may follow the geodesics of different metric frames, and the need for a frame-independent regularization of curvature singularities.

description: Exceptional responders (ER) are those cancer "patients whom a complete or partial response was expected in less than 10% of similarly treated patients or whose duration of response lasted three times the published median or longer” (Wheeler et al. 2020). This represents a puzzling case for mainstream cancer research. The Tissue Organization Field Theory (TOFT) could instead explain it, by positing that the initiation and progression of cancer is due to the disruption of the normal interaction of cells and tissues, and that proliferation is the default state of all cells (Sonnenschein & Soto 2020). An increasing number of observations suggest that cancer initiation and its progression, or regression, are not primarily caused by intracellular processes but should be considered, instead, relational phenomena occurring in tissues, involving the entire organism and its environment.

description: Singular incentive mechanisms are not a panacea for all environmental problems. In the majority of cases, a mix of instruments tailored to specific policy and Natural Resource Management (NRM) goals will be the most effective response to environmental problems. This paper presents a framework that has been designed to act as a guide to the selection, design and delivery of an incentive mechanism (or mechanisms) by aligning the issues, dynamics and operating structure of a group of landholders with a mix of ‘best fit’ incentives. The framework does this by collecting information through a series of checklist questions and subsequently uses a matrix and ranked criteria to analyse the information. The framework has been used on a trial basis and the outcomes have revealed encouraging trends which have helped to move the incentives debate forward.

description: Galaxy shapes have been observed to align with external tidal fields generated by the large-scale structures of the Universe. While the main source for these tidal fields is provided by long-wavelength density perturbations, tensor perturbations also contribute with a non-vanishing amplitude at linear order. We show that parity-breaking gravitational waves produced during inflation leave a distinctive imprint in the galaxy shape power spectrum which is not hampered by any scalar-induced tidal field. We also show that a certain class of tensor non-Gaussianities produced during inflation can leave a signature in the density-weighted galaxy shape power spectrum. We estimate the possibility of observing such imprints in future galaxy surveys.

description: The Australian wine industry has been under the pressure of oversupply for many years. Export promotion appears to potentially serve as an effective strategy to partially address this problem. An Hedonic price function is employed to estimate premia and discounts for various varieties, regions and vintages of Australian wine, within the US retail market. Some preliminary results are presented. These results may be used to develop an optimal allocation of Australian wine to various overseas and domestic markets.
Neutrino Masses with "Zero Sum" Condition: $m_{ν_1} + m_{ν_2} + m_{ν_3} = 0$

description: It is well known that the neutrino mass matrix contains more parameters than experimentalists can hope to measure in the foreseeable future even if we impose CP invariance. Thus, various authors have proposed ansatzes to restrict the form of the neutrino mass matrix further. Here we propose that $m_{ν_1} + m_{ν_2} + m_{ν_3} = 0$; this ``zero sum'' condition can occur in certain class of models, such as models whose neutrino mass matrix can be expressed as commutator of two matrices. With this condition, the absolute neutrino mass can be obtained in terms of the mass-squared differences. When combined with the accumulated experimental data this condition predicts two types of mass hierarchies, with one of them characterized by $m_{ν_3} \approx -2m_{ν_1} \approx -2 m_{ν_2} \approx 0.063$ eV, and the other by $m_{ν_1} \approx -m_{ν_2} \approx 0.054$ eV and $m_{ν_3} \approx 0.0064$ eV. The mass ranges predicted is just below the cosmological upper bound of 0.23 eV from recent WMAP data and can be probed in the near future. We also point out some implications for direct laboratory measurement of neutrino masses, and the neutrino mass matrix.

Thermal Fluctuations and Black Hole Entropy

description: In this paper, we consider the effect of thermal fluctuations on the entropy of both neutral and charged black holes. We emphasize the distinction between fixed and fluctuating charge systems; using a canonical ensemble to describe the former and a grand canonical ensemble to study the latter. Our novel approach is based on the philosophy that the black hole quantum spectrum is an essential component in any such calculation. For definiteness, we employ a uniformly spaced area spectrum, which has been advocated by Bekenstein and others in the literature. The generic results are applied to some specific models; in particular, various limiting cases of an (arbitrary-dimensional) AdS-Reissner-Nordstrom black hole. We find that the leading-order quantum correction to the entropy can consistently be expressed as the logarithm of the classical quantity. For a small AdS curvature parameter and zero net charge, it is shown that, independent of the dimension, the logarithmic prefactor is +1/2 when the charge is fixed but +1 when the charge is fluctuating.We also demonstrate that, in the grand canonical framework, the fluctuations in the charge are large, $ΔQ\simΔA\sim S_{BH}^{1/2}$, even when $ =0$. A further implication of this framework is that an asymptotically flat, non-extremal black hole can never achieve a state of thermal equilibrium.

description: In the Standard Model, chiral electroweak anomalies predict nonperturbative interactions that violate baryon ($B$) plus lepton number ($L$). The potential observability of these processes at colliders has been amply discussed in the literature, mostly focusing on the impact of the accompanying boson emission, which contributes to the cross sections through an exponential function of the center-of-mass energy. We focus instead on the impact of exotic fermions charged under $SU(2)_L$, which not only can be emitted in these processes, but also affect the non-exponential contributions to the cross-sections. Estimating the latter using instanton techniques, we find sizable effects that suggest that if $B+L$-violating processes are ever seen at colliders, they may involve physics beyond the Standard Model.

description: The potential for supplementing sparse economic data and aggregate production data with a detailed specification of land quality constraints obtained from a Geographical Information System, in order to parameterise a regional model of rice acreage response in Vietnam, is investigated in this paper. It is asserted that such an approach has advantages in terms of improved credibility amongst agricultural scientists cum policy makers because of the detailed attention to land capability, compared to conventional elasticity based approaches that are commonly used for agricultural policy analysis when data is scarce. The approach relies on the use of Positive Mathematical Programming to calibrate the acreage response for land classes where more than one farming system is observed in the baseline data. Sensitivity of the model to the nature of the calibration assumptions are presented, and results regarding acreage response with respect to rice prices, in different seasons and regions are presented and discussed. It is concluded that while the current model relies on some heroic assumptions regarding interpretation of the available information, it could be improved considerably, and at low cost, if taken up and developed within the Ministry. There remains, however, a research agenda regarding farm household decision making in rice based production systems of Vietnam that could provide for improved calibration in the future.

description: We study the forward-backward asymmetries in the decays of $K^+\toπ^+\ell^+ \ell^-$ ($\ell=e$ and $μ$) in the presence of scalar or tensor terms. We find that with the scalar (tensor) type interaction the asymmetry can be up to ${\cal O}(10^{-3})$ (${\cal O}(10^{-1}))$ and arbitrary large for the electron and muon modes, respectively, without conflict with the experimental data. We also discuss the cases in the minimal supersymmetric standard model where the scalar terms can be induced. In particular we show that the asymmetry in $K^+\toπ^+μ^+μ^-$ can be as large as ${\cal O}(10^{-3})$ in the large $\tanβ$ limit, which can be tested in future experiments such as CKM at Fermilab.

description: The modern lifestyle is associated with exposure to “psychological” or “emotional” stress. A growing portion of the population is exposed to emotional stress that results in a high incidence of anxiety disorders, a serious social problem. With this rise, there is a need for understanding the neurobiological causes of stress-induced anxiety and to offer safe remedies for this condition. Side effects of existing pharmaceuticals necessitate the search for alternatives. Having fewer adverse effects than classic remedies, natural extract-based therapies can be a promising solution. Here, we applied a model of emotional stress in BALB/c mice using ultrasound exposure to evoke the signs of anxiety-like behavior. We examined the behavioral and molecular impact of ultrasound and administration of herbal antioxidant/anti-inflammatory treatment (HAT) on AMPA receptor expression, markers of plasticity, inflammation and oxidative stress. A 3-week ultrasound exposure increased scores of anxiety-like behaviors in the standard tests and altered hippocampal expression as well as internalization of AMPA receptor subunits GluA1-A3. Concomitant treatment with HAT has prevented increases of anxiety-like behaviors and other behavioral changes, normalized hippocampal malondialdehyde content, GSK3β and pro-inflammatory cytokines Il-1β and Il-6, and the number of Ki67-positive cells. Levels of malondialdehyde, a common measure of oxidative stress, significantly correlated with the investigated end-points in stressed, but not in non-stressed animals. Our results emphasize the role of oxidative stress in neurobiological abnormalities associated with experimentally induced condition mimicking emotional stress in rodents and highlight the potential therapeutic use of anti-oxidants like herbal compositions for management of stress-related emotional disturbances within the community.

description: We review a few topics in Planck-scale physics, with emphasis on possible manifestations in relatively low energy. The selected topics include quantum fluctuations of spacetime, their cumulative effects, uncertainties in energy-momentum measurements, and low energy quantum-gravity phenomenology. The focus is on quantum-gravity-induced uncertainties in some observable quantities. We consider four possible ways to probe Planck-scale physics experimentally: 1. looking for energy-dependent spreads in the arrival time of photons of the same energy from GRBs; 2. examining spacetime fluctuation-induced phase incoherence of light from extragalactic sources; 3. detecting spacetime foam with laser-based interferometry techniques; 4. understanding the threshold anomalies in high energy cosmic ray and gamma ray events. Some other experiments are briefly discussed. We show how some physics behind black holes, simple clocks, simple computers, and the holographic principle is related to Planck-scale physics. We also discuss a formulation of the Dirac equation as a difference equation on a discrete Planck-scale spacetime lattice, and a possible interplay between Planck-scale and Hubble-scale physics encoded in the cosmological constant (dark energy).

description: In response to increasing awareness of climate change, the Howard government implemented the Mandatory Renewable Energy Target (MRET) in 2001. It requires electricity wholesalers to source an additional 9500 GWh of electricity from renewable sources by 2010. Electricity wholesalers are required to subsidise renewable energy generators by purchasing Renewable Energy Certificates (RECs) equivalent to the target; failure to do so incurs a penalty of $40 per megawatt. Economic analysis is used to investigate the design and likely operation and limitations of the MRET.

Studies which examine pricing and consumer preferences for local foods available outside of their normal season are few. One study finds that consumers would be willing to attend farmers’ markets in the off-season, but does not assess their willingness to pay (WTP) for products in the off-season. A second study mentions that extending the market season may increase farmer income, but does not specifically discuss impacts to net returns resulting from price differentials. This study will assess enhanced revenue potential for out-of-season (winter, early spring, late fall) direct market sales, specifically those which can be produced through the use of season extension techniques such as high tunnels. The results of this study will provide agricultural producers with valuable information regarding potential revenue estimates which they can use to assess the financial impacts of implementing season extension techniques into their operation. Study methods include a comparison of availability and pricing for fruit and vegetable products from May through October at farmers’ markets in Utah and Colorado; a survey of farmers’ market managers on the potential for extending the farmers market season; a survey of growers and Extension horticulturalists on the potential products and length of season extension for fruit and vegetable crops; and finally choice experiments designed to examine consumer WTP for local fruit and vegetable products across seasons.

description: The unusual class of magnetized nonthermal radio filaments (NTF), threads and streaks with their unique physical characteristics are found only within the inner couple of degrees of the Galactic center. Also, a number of young, mass-losing and rare stellar clusters are recognized to lie in the Galactic center region. The latter characteristic of the Galactic center region is used to explain the origin of the nonthermal radio filaments. We consider a mechanism in which the collective winds of massive WR and OB stars within a dense stellar environment produce shock waves that can accelerate particles to relativistic energies. This mechanism is an extension of a model originally proposed by Rosner and Bodo (1996), who suggested that energetic nonthermal particles are produced in a terminal shock of mass-losing stars. The large-scale distribution of the magnetic field in the context of this model is argued to have neither poloidal geometry nor pervasive throughout the Galactic center region.

description: Asphalt is a visco-elastic material having properties of elastic solid at low temperature and viscous liquid at high temperature. Properties of asphalt binder depend upon temperature, rate of loading and aging conditions. Although asphalt binder is only 4-5 % of asphalt concrete mix by weight but it plays a vital role in defining the pavement performance. That is, pavement response is heavily dependent upon the viscous and elastic properties of asphalt. In this research six asphalt samples were obtained from Attock and Karachi oil refinery and Dynamic Shear Rheometer was used in the laboratory to evaluate their viscous and elastic properties. Witczak predictive model was used to predict the binder viscosity and phase angle by using complex shear modulus and viscosity temperature susceptibility. The study revealed that Karachi virgin asphalt grades are more elastic as compared to Attock virgin asphalt grades both at low and high temperature. Similarly Attock PMB is more stiff and elastic as compared to Karachi 40/50, 60/70, and Attock 60/70. The research also revealed that Attock PMB has lesser temperature susceptibility as compared to virgin grades which makes it more suitable to resist rutting and cracking in extreme climatic conditions of Pakistan.

description: Subspace segmentation assumes that data comes from the union of different subspaces and the purpose of segmentation is to partition the data into the corresponding subspace. Low-rank representation (LRR) is a classic spectral-type method for solving subspace segmentation problems, that is, one first obtains an affinity matrix by solving a LRR model and then performs spectral clustering for segmentation. This paper proposes a group norm regularized factorization model (GNRFM) inspired by the LRR model for subspace segmentation and then designs an Accelerated Augmented Lagrangian Method (AALM) algorithm to solve this model. Specifically, we adopt group norm regularization to make the columns of the factor matrix sparse, thereby achieving a purpose of low rank, which means no Singular Value Decompositions (SVD) are required and the computational complexity of each step is greatly reduced. We obtain affinity matrices by using different LRR models and then performing cluster testing on different sets of synthetic noisy data and real data, respectively. Compared with traditional models and algorithms, the proposed method is faster and more robust to noise, so the final clustering results are better. Moreover, the numerical results show that our algorithm converges fast and only requires approximately ten iterations.

description: Although food safety training is important for the food services industry, there is limited information on the needs for hard-to-reach food service workers. The objectives of this paper are to - (1) identify food safety training issues facing hard-to-reach food service workers, and (2) analyze the opinions collected of participants in food safety focus groups. Data reported in this paper were collected using focus group meetings from selected counties in TN. Qualitative methodology was applied to data collected. Findings showed that food safety training should be offered on a continuous basis using materials that are easy to read, understand and implement. An effective food safety training program is needed to monitor employees to ensure compliance with established guidelines and procedures.

Determination of a Wave Function Functional

description: In this paper we propose the idea of expanding the space of variations in standard variational calculations for the energy by considering the wave function $ψ$ to be a functional of a set of functions $χ: ψ= ψ[χ]$, rather than a function. In this manner a greater flexibility to the structure of the wave function is achieved. A constrained search in a subspace over all functions $χ$ such that the wave function functional $ψ[χ]$ satisfies a constraint such as normalization or the Fermi-Coulomb hole charge sum rule, or the requirement that it lead to a physical observable such as the density, diamagnetic susceptibility, etc. is then performed. A rigorous upper bound to the energy is subsequently obtained by variational minimization with respect to the parameters in the approximate wave function functional. Hence, the terminology, the constrained-search variational method. The \emph{rigorous} construction of such a constrained-search--variational wave function functional is demonstrated by example of the ground state of the Helium atom.

Jet direction in bubble collapse within rectangular and triangular channels

Year: 2019
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: A vapor bubble collapsing near a solid boundary in a liquid produces a liquid jet that points toward the boundary. The direction of this jet has been studied for boundaries such as flat planes and parallel walls enclosing a channel. Extending these investigations to enclosed polygonal boundaries, we experimentally measure jet direction for collapsing bubbles inside a square and an equilateral triangular channel. Following the method of Tagawa and Peters (Phys. Rev. Fluids 3, 081601, 2018) for predicting the jet direction in corners, we model the bubble as a sink in a potential flow and demonstrate by experiment that analytical solutions accurately predict jet direction within an equilateral triangle and square. We further use the method to develop predictions for several other polygons, specifically, a rectangle, an isosceles right triangle, and a $30^{\circ}$-$60^{\circ}$-$90^{\circ}$ right triangle.

description: Pairs of Standard Model fermions form dimension-3 singlet operators that can couple to new dark sector states. This "fermion portal" is to be contrasted with the lower-dimensional Higgs, vector and neutrino singlet portals. We characterise its distinct phenomenology and place effective field theory bounds on this framework, focusing on the case of fermion portals to a pair of light dark sector fermions. We obtain current and projected limits on the dimension-6 effective operator scale from a variety of meson decay experiments, missing energy and long-lived particle searches at colliders, as well as astrophysical and cosmological bounds. The DarkEFT public code is made available for recasting these limits, which we illustrate with various examples including an integrated-out heavy dark photon.
