description:  Nanosized Ni0.65Zn0.35Fe2-xInxO4 with x = 0.0, 0.08, 0.16, and 0.24 spinel ferrites were prepared by using sol-gel auto combustion method. The DC resistivity studies of all the samples were carried out by two-probe technique as a function of temperature and the results revealed the semiconducting behavior. Moreover, Arrhenius plots indicate that as a function of In3+ doping the resistivity was found to increase. The activation energy determined using standard formula indicates increment with In3+. Additionally, drift mobility and diffusion coefficient were computed using DC resistivity data. Both drift mobility and diffusion coefficient were found to decrease with In3+, related to enhanced charge carrier concentration and production of cation vacancies respectively.

description: In the emerging knowledge economy, universities are adopting a key role as producers of scientific knowledge and skills, and they are experiencing far reaching changes in their tasks. Their main mission is no longer confined to education and research, but increasingly also covers technology transfer and commercialisation activities. The aim of this paper is to examine to what extent this phenomenon could also be observed in Austria, a country which is not a pio-neer regarding the development of the knowledge economy. Moreover, we are interested in the particular mechanisms of knowledge transfer. We differentiate between four key tasks of uni-versities, including their roles as ―antennae‖ for receiving external knowledge, sources of highly skilled labour, cooperation partners for the industry and seedbeds for new firm formation. Fo-cusing on the biotechnology sector we will demonstrate that an opening of the ivory tower and a move of Austrian universities towards the market place has occurred. Furthermore, we will show that these changes to some extent have been policy-driven in nature.

description: We propose a new approach to the spinor-spinor R-matrix with orthogonal and symplectic symmetry. Based on this approach and the fusion method we relate the spinor-vector and vector-vector monodromy matrices for quantum spin chains. We consider the explicit spinor R matrices of low rank orthogonal algebras and the corresponding RTT algebras. Coincidences with fundamental R matrices allow to relate the Algebraic Bethe Ansatz for spinor and vector monodromy matrices.

description: A data-driven framework is developed to represent chaotic dynamics on an inertial manifold (IM), and applied to solutions of the Kuramoto-Sivashinsky equation. A hybrid method combining linear and nonlinear (neural-network) dimension reduction transforms between coordinates in the full state space and on the IM. Additional neural networks predict time-evolution on the IM. The formalism accounts for translation invariance and energy conservation, and substantially outperforms linear dimension reduction, reproducing very well key dynamic and statistical features of the attractor.

description: Focusing on the narrower concept of a knowledge-economy-based growth strategy, this paper explores whether a strong link between a college-educated population and a region’s economic performance was an important ingredient in the growth experience of the Sunbelt during the 1990s. The issue is addressed through analysis of two different datasets. First, the education and income characteristics of the people moving to the Sunbelt region are examined using migration data from the 2000 census. Then we look at the link between the knowledge-economy metric of the share of college educated adults and economic growth in the Sunbelt in the 1990s using data for 116 Sunbelt MSAs. The results of our analysis provide little evidence that a college educated workforce was a major factor promoting economic growth in Sunbelt cities during that period.

We introduce a complete set of tools for doing and analyzing the results of simulations at fixed NVE and NVT. The modular format of the paper allows readers to select sections that meet their needs. We start with an introduction to molecular dynamics independent of the programming language, followed by introductions to an implementation using Python and then the freely available open source software package LAMMPS. We also describe analysis tools for the quick testing of the program during its development and compute the radial distribution function and the mean square displacement using both Python and LAMMPS.

description: Opposite spin Landau levels in a quantum well can be brought into coincidence by tilting the magnetic field away from normal orientation. We demonstrate that the magnetotransport anomaly at integer filling factors that was recently discovered by Pan {\it et al} is due to such a coincidence. By performing exact diagonalization calculations using microscopically evaluated effective electron-electron interactions, we are able to establish that the electronic ground state at coincidence is an Ising quantum Hall ferromagnet and that the low energy excitations correspond to the formation of a domain wall.

description: Long-duration gamma-ray bursts (GRBs) are understood to be the final fate for a subset of massive, stripped envelope, rapidly rotating stars. Beyond this, our knowledge of the progenitor systems is limited. Using the BPASS (Binary Population and Spectral Synthesis) stellar evolution models, we investigate the possibility that some massive stars in binaries can maintain the angular momentum required for jet production, while still loosing their outer envelope through winds or binary interactions. We find that a total hydrogen mass of less than 0.0005 Msun and a helium ejecta mass fraction of less than 0.20 provide the best thresholds for the supernova type II/Ibc and Ib/Ic divisions respectively. Tidal interactions in binaries are accounted for by applying a tidal algorithm to post-process the stellar evolution models output by BPASS. We show that the observed volumetric gamma-ray burst rate evolution can be recreated using two distinct pathways and plausible distributions for burst parameters. In the first pathway, stars are spun up by mass accretion into a quasi-homogeneous state. In the second, tides maintain rotation where otherwise the star would spin down. Both lead to type Ic supernova progenitors, and a metallicity distribution consistent with the GRB host galaxy population. The inferred core angular momentum threshold for jet production is consistent with theoretical requirements for collapsars, given the assumptions made in our model. We can therefore reproduce several aspects of core collapse supernova/GRB observation and theory simultaneously. We discuss the predicted observable properties of GRB progenitors and their surviving companions.

Disoriented Chiral Condensate and Charge-Neutral Particle Fluctuations in Heavy Ion Collisions

description: The posibility of large charge and isospin fluctuations in high-energy heavy ion-collisions is studied within the framework of the nonlinear $σ$-model with quark degrees of freedom. The multipion exchange potential between two quarks is derived. It is shown that the soft chiral pion bremsstralung leads to anomalously large fluctuations in the ratio of neutral to charged pions, predicted by the formation of a disoriented chiral condensate (DCC). The factorization property of the scattering amplitude in the impact parameter space of the leading two-nucleon system is used to study semiclassical production of pions in the central region. We show that the DCC-type fluctuations are suppressed if a large number of pions are produced in $ρ$-type clusters. Our conclusion is supported through the calculation of two pion correlation parameters as a function of the $ρ$-to-$π$ ratio.

description: We investigate the stability and $e^+e^-$ pair creation of supercritically charged superheavy nuclei, $ud$QM nuggets, strangelets, and strangeon nuggets based on Thomas-Fermi approximation. The model parameters are fixed by reproducing their masses and charge properties reported in earlier publications. It is found that $ud$QM nuggets, strangelets, and strangeon nuggets may be more stable than ${}^{56}$Fe at $A\gtrsim 315$, $5\times10^4$, and $1.2\times10^8$, respectively. For those stable against neutron emission, the most massive superheavy element has a baryon number $\sim$965, while $ud$QM nuggets, strangelets, and strangeon nuggets need to have baryon numbers larger than $39$, 433, and $2.7\times10^5$. The $e^+e^-$ pair creation will inevitably start for superheavy nuclei with charge numbers $Z\geq177$, $ud$QM nuggets with $Z\geq163$, strangelets with $Z\geq 192$, and strangeon nuggets with $Z\geq 212$. A universal relation $Q/R_e = \left(m_e - \barμ_e\right)/α$ is obtained at a given electron chemical potential $\barμ_e$, where $Q$ is the total charge and $R_e$ the radius of electron cloud. This predicts the maximum charge number by taking $\barμ_e=-m_e$. For supercritically charged objects with $\barμ_e

We extended the spectrum to lower energies using archival GRANAT and ASCA observations.

description: Under heating, $α$-AlF$_3$ undergoes a structural phase transition from rhombohedral to cubic at temperature $T$ around 730 K. The density functional method is used to examine the $T$=0 energy surface in the structural parameter space, and finds the minimum in good agreement with the observed rhombohedral structure. The energy surface and electronic wave-functions at the minimum are then used to calculate properties including density of states, $Γ$-point phonon modes, and the dielectric function. The dipole formed at each fluorine ion in the low temperature phase is also calculated, and is used in a classical electrostatic picture to examine possible antiferroelectric aspects of this phase transition.

description: The possibility is indicated of applying the theory of superconductors with overlapping energy bands to describe the thermodynamic and electromagnetic properties of the high-temperature compounds $La_{2-x}(Ba,Sr)_xCuO_4$ and $YBa_2Ci_3O_{7-δ}$. The two-band model was used to obtain high values of $T_c$, two energy gaps $2Δ_1/T_c > 3.5$ and $2Δ_2/T_c < 3.5$, large negative values of $d\ln T_c/d\ln V$ ($V$ is the volume) in lanthanum ceramics, small values of the jump in the electron heat capacity at $T=T_c$, negative curvature of the upper critical magnetic field $H_{c2}$ near the transition temperature, etc. Such behavior of the above quantities is observed experimentally. A description is also obtained of the decrease in $T_c$ as the disordering of oxygen increases, and also as copper atoms are replaced by a nonmagnetic impurity (Al, Zn, etc.). The main mechanism responsible for this decrease is the interband scattering of electrons by impurities and by randomly distributed oxygen vacancies. A theory has been developed of multiband superconductors which takes into account the points of high symmetry in momentum space. On the basis of this theory one can explain the existence of a plateau in the dependence of $T_c$ on $δ$ for $YBa_2Cu_3O_{7-δ}$, and also in the dependence of $T_c$ on $x$ for $La_{2-x}(Ba,Sr)_xCuO_4$, that has been observed in a number of experiments. Moreover, this theory also explains the presence of two maxima in the dependence of $T_c$ on pressure for $Bi_2Sr_2CaCu_2O_8$.

description: Traditionally, publicly available repositories of certificates offer the usual response to the problem of public key distribution. After issuing a public-key certificate a certification authority (CA) - in the frame of a particular public-key infrastructure (PKI) - will store and publish that certificate in a repository so that, at a later moment, end-users can search, find and retrieve public-key certificates. A known and still persisting drawback of this approach is that these repositories are not interconnected between each other on an Internet scale, therefore the search and retrieving of certificates on a wider scale turns out to be very difficult. In this scenario, end-users are supposed to know the Internet location of the repository before actually starting the procedure of search and retrieval. Currently, there are no means to perform automatic discovery of authoritative repositories for a particular certificate using as a search-key some information identifying an Internet entity. In this paper, we try to describe a different approach for solving the key distribution problem. This solution takes into account an already existing Internet-wide infrastructure: the domain name system (DNS).

description: This article introduces the status quo of consumer credit business in China's agricultural bank, indicating that the scale of China's consumer credit business is expanded year by year; the growth of consumer credit business slows down; housing loans grow rapidly. We analyze issues concerning development of consumer credit business in agricultural bank as follows: single variety of consumer credit business makes the operating scope narrow; the formality of consumer credit business is trivial, abating consumers' will to borrow; consumers' consumer attitudes are stale, yet to be further changed; the loan interest of consumer credit is beyond the majority of consumers' actual ability to pay; the existing regulations and systems are not sound; the risk prevention mechanism is not perfect. Based on this, we put forward the following countermeasures and proposals for further improving consumer credit business in China's agricultural bank: first, formulate reasonable marketing strategy of consumer credit business; second, establish and improve the internal management mechanism; third, establish and improve risk assessment system; fourth, improve consumer credit legal system.

description: Edit-distance-based string similarity search has many applications such as spell correction, data de-duplication, and sequence alignment. However, computing edit distance is known to have high complexity, which makes string similarity search challenging for large datasets. In this paper, we propose a deep learning pipeline (called CNN-ED) that embeds edit distance into Euclidean distance for fast approximate similarity search. A convolutional neural network (CNN) is used to generate fixed-length vector embeddings for a dataset of strings and the loss function is a combination of the triplet loss and the approximation error. To justify our choice of using CNN instead of other structures (e.g., RNN) as the model, theoretical analysis is conducted to show that some basic operations in our CNN model preserve edit distance. Experimental results show that CNN-ED outperforms data-independent CGK embedding and RNN-based GRU embedding in terms of both accuracy and efficiency by a large margin. We also show that string similarity search can be significantly accelerated using CNN-based embeddings, sometimes by orders of magnitude.

description: Through field experiment, we explore the impact of long-term drip fertigation on growth and distribution of lychee root and changes of soil PH in different layers of soil in lychee garden. The results show that drip fertigation can significantly promote the growth of lychee roots, and increase the contact area of root and soil; if it experiences six years of drip fertigation successively, the dry weight of root, root length and surface area of root in soil in drip fertigation area, will be 2.29 times, 2.17 times and 2.25 times that in non-drip fertigation area, respectively. The lychee root is mainly distributed in 0-40cm layer of soil, but there is conspicuous difference between drip fertigation area and non-drip fertigation area in terms of root distribution in 0-20cm and 20-40cm layer of soil. Drip fertigation is more favorable for the root to go deep inside the soil. Under long-term drip fertigation, the soil acidification in lychee garden is prominent, and in comparison with non-drip fertigation area, there is the greatest decline in soil PH in 10-20cm layer of soil in drip fertigation area, reaching 1.47 units.
A new dual representation for staggered lattice QCD

description: We propose a new strategy to evaluate the partition function of lattice QCD with Wilson gauge action coupled to staggered fermions, based on a strong coupling expansion in the inverse bare gauge coupling $β= 2N/g^{2}$. Our method makes use of the recently developed formalism to evaluate the ${\rm SU}(N)$ $1-$link integrals and consists in an exact rewriting of the partition function in terms of a set of additional dual degrees of freedom which we call "Decoupling Operator Indices" (DOI). The method is not limited to any particular number of dimensions or gauge group ${\rm U}(N)$, ${\rm SU}(N)$. In terms of the DOI the system takes the form of a Tensor Network which can be simulated using Worm-like algorithms. Higher order $β$-corrections to strong coupling lattice QCD can be, in principle, systematically evaluated, helping to answer the question whether the finite density sign problem remains mild when plaquette contributions are included. Issues related to the complexity of the description and strategies for the stochastic evaluation of the partition function are discussed.

description: Decentral renewable energy supply requires a higher number of plants and affected residents since centuries. Despite many advantages, like e.g. reduction of greenhouse gases due to use of renewable energies, residents are confronted with various emissions due to such plants. However, the turnaround to regenerative energy supply can only be realized if citizens accept these new technologies in their neighborhood. This paper presents the findings of two surveys concerning public acceptance of biomass cogeneration plants (BCP's) and biogas plants (BGP's) in Bavaria/Germany. Data was collected at 5,000 households in the neighborhoods of ten BCP sites and one BGP site. Results show a high level of public acceptance, lacking information among residents, almost no Not-in-my-Backyard behavior (NIMBYism) and essential differences between incentives and arguments of proponents and opponents of plants. Findings deliver useful information concerning project development to plant operators.
Down-Sizing in Galaxy Formation at z~1 in the Subaru/XMM-Newton Deep Survey (SXDS)

description: We use the deep wide-field optical imaging data of the Subaru/XMM-Newton Deep Survey (SXDS) to discuss the luminosity (mass) dependent galaxy colours down to z'=25.0 (5 x 10^9 h_{70}^{-2} Msun) for z~1 galaxies in colour-selected high density regions. We find an apparent absence of galaxies on the red colour-magnitude sequence below z'~24.2, corresponding to ~M*+2 (~10^{10} Msun) with respect to passively evolving galaxies at z~1. Galaxies brighter than M*-0.5 (8 x 10^{10} Msun), however, are predominantly red passively evolving systems, with few blue star forming galaxies at these magnitudes. This apparent age gradient, where massive galaxies are dominated by old stellar populations while less massive galaxies have more extended star formation histories, supports the `down-sizing' idea where the mass of galaxies hosting star formation decreases as the Universe ages. Combined with the lack of evolution in the shape of the stellar mass function for massive galaxies since at least z~1, it appears that galaxy formation processes (both star formation and mass assembly) should have occurred in an accelerated way in massive systems in high density regions, while these processes should have been slower in smaller systems. This result provides an interesting challenge for modern CDM-based galaxy formation theories which predict later formation epochs of massive systems, commonly referred to as ``bottom-up''.

description: We present the results of a detailed investigation of the prompt and afterglow emission in the HESS detected GRB 190829A. Swift and Fermi observations of the prompt phase of this GRB reveal two isolated sub-bursts or episodes, separated by a quiescent phase. The energetic and the spectral properties of the first episode are in stark contrast to the second. The first episode, which has a higher spectral peak of $\sim 120\:\text{keV}$ and a low isotropic energy $\sim 10^{50}\:\text{erg}$ is an outlier to the Amati correlation and marginally satisfies the Yonetoku correlation. However, the energetically dominant second episode has lower peak energy and is consistent with the above correlations. We compared this GRB to other low luminosity GRBs (LLGRBs). Prompt emission of LLGRBs also indicates a relativistic shock breakout origin of the radiation. For GRB 190829A, some of the properties of a shock breakout origin are satisfied. However, the absence of an accompanying thermal component and energy above the shock breakout critical limit precludes a shock breakout origin. In the afterglow, an unusual long-lasting late time flare of duration $\sim 10^4\:\text{s}$ is observed. We also analyzed the late-time \fermi-LAT emission that encapsulates the H.E.S.S. detection. Some of the LAT photons are likely to be associated with the source. All the above observational facts suggest GRB 190829A is a peculiar low luminosity GRB that is not powered by a shock breakout, and with an unusual rebrightening due to a patchy emission or a refreshed shock during the afterglow. Furthermore, our results show that TeV energy photons seem common in both high luminosity GRBs and LLGRBs.

description: The outcomes of a survey analysing public acceptance of biomass cogeneration heat (and power) plants (BCH(P)P's) of 3,000 Bavarian households in the neighbourhood of ten BCH(P)P's are reported in this paper. Acceptance was measured in two different distances to plants in order to check for the so-called "Not-in-my-backyard effect" (NIMBYism): Nearby regions (0-500 m) and distant regions (2,000 m plus). The survey results show that public acceptance is better than expected and interviewees only feel very little disturbed by BCH(P)P's. The motives of plants' proponents fundamentally differ from the motives of the few opponents, who mainly raise egoistic reasons, whereas proponents have a look on their regions' welfare respectively the well-being of the planet. Furthermore, there are huge deficits in residents' information. There is only little evidence for distance-related NIMBYism in case of the surveyed sites. In contrast, aspects like "heat-delivery", "attitudes towards renewable energies" and "degree of information" have significant impact on the acceptance of the respondents. Besides the factors "plant-size", "attitudes towards plants in the planning phase" and "runtime" (regardless the acceptance status in the planning phase) seem to affect public acceptance for years. Furthermore, public acceptance tends to change to an intermediate level - even if acceptance in the planning phase was high.
A consistency-test for determining whether ultra-compact dwarf galaxies could be the remnant nuclei of threshed galaxies

description: It has been suggested that ultra-compact dwarf (UCD) galaxies are the "threshed'" remains of larger galaxies. Simulations have revealed that extensive tidal-stripping may pare a galaxy back to its tightly-bound, compact nuclear star cluster. It has therefore been proposed that the two-component nature of UCD galaxies may reflect the original nuclear star cluster surrounded by the paltry remnants of its host galaxy. A simple quantitative test of this theory is devised and applied here. If the mass of the central black hole in UCD galaxies, relative to the mass of the UCD galaxies' inner stellar component, i.e. the suspected nuclear star cluster, matches with the (black hole mass)-(nuclear star cluster mass) relation observed in other galaxies, then it would provide quantitative support for the stripped galaxy scenario. Such consistency is found for four of the five UCD galaxies reported to have a massive black hole. The (black hole mass)-(nuclear star cluster mass) relation is then used to predict the central black hole mass in two additional UCD galaxies, and to reveal that NGC 205 and possibly NGC 404 (which only has an upper limit to its black hole mass) also follow this scaling relation.

description: A recently published article by a widely diffused Italian newspaper (Il Corriere della Sera), claims that the “rate of curability of cancer, in the next 10-15 years will be astonishingly increased”. That exploit could mainly be attributed (no doubt on that!) to the claims made by new generation molecular drugs designed to single out and then to ‘block’ one or more genes involved in cancer “causation”.

description: We have measured the absolute proper motion of the Fornax dwarf spheroidal galaxy from a combination of photographic plate material and HST WFPC2 data that provide a time baseline of up to 50 years. The extragalactic reference frame consists of 8 QSO images and 48 galaxies. The absolute proper motion is mu_alpha cos(delta) = 0.59 +-0.16 mas/yr and mu_delta = -0.15 +- 0.16 mas/yr. The corresponding orbit of Fornax is polar, with an eccentricity of 0.27, and a radial period of 4.5 Gyr. Fornax's current location is near pericenter. The direction of the motion of Fornax supports the notion that Fornax belongs to the Fornax-LeoI-LeoII-Sculptor-Sextans stream as hypothesized by Lynden-Bell (1976, 1982) and Majewski (1994). According to our orbit determination, Fornax crossed the Magellanic plane \~190 Myr ago, a time that coincides with the termination of the star-formation process in Fornax. We propose that ram-pressure stripping due to the passage of Fornax through a gaseous medium denser than the typical intragalactic medium left behind from the LMC may have caused the end of star formation in Fornax. The excess, anomalous clouds within the South Galactic pole region of the Magellanic Stream whose origin has long been debated in the literature as constituents of either the Magellanic Stream or of the extragalactic Sculptor group, are found to lie along the orbit of Fornax. We speculate that these clouds are stripped material from Fornax as the dwarf crossed the Magellanic Clouds' orbit.

description: We perform the linear stability analysis for a new model for poromechanical processes with inertia (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing and reacting solutes convected in the medium. We find parameter regions that lead to spatio-temporal instabilities of the coupled system. The mutual dependences between deformation and diffusive patterns are of substantial relevance in the study of morphoelastic changes in biomaterials. We provide a set of computational examples in 2D and 3D (related to brain mechanobiology) that can be used to form a better understanding on how, and up to which extent, the deformations of the porous structure dictate the generation and suppression of spatial patterning dynamics, also related to the onset of mechano-chemical waves.
(No) Wigner Theorem for C*-algebras

description: Wigner's Theorem states that bijections of the set P_1(H) of one-dimensional projections on a Hilbert space H that preserve transition probabilities are induced by either a unitary or an anti-unitary operator on H (which is uniquely determined up to a phase). Since elements of P_1(H) define pure states on the C*-algebra B(H) of all bounded operators on H (though typically not producing all of them), this suggests possible generalizations to arbitrary C*-algebras. This paper is a detailed study of this problem, based on earlier results by R.V. Kadison (1965), F.W. Shultz (1982), K. Thomsen (1982), and others. Perhaps surprisingly, the sharpest known version of Wigner's Theorem for C*-algebras (which is a variation on a result from Shultz, with considerably simplified proof) generalizes the equivalence between the hypotheses in the original theorem and those in an analogous result on (anti) unitary implementability of Jordan automorphisms of B(H), and does not yield (anti) unitary implementability itself, far from it: abstract existence results that do give such implementability seem arbitrary and practically useless. As such, it would be fair to say that there is no Wigner Theorem for C*-algebras.

On the Physical Meaning of Time-Domain Constitutive Models with Complex Parameters
Creators: name: Makris, Nicos

Year: 2019
Subjects: subject: Classical Physics (physics.class-ph)

description: This paper revisits the physical meaning of linear, time-domain constitutive models with complex parameters that have been presented in the literature and concludes that such models are not physically realizable. While complex-parameter phenomenological models (including those with complex-order time derivatives) may be efficient in capturing in the frequency domain the frequency-dependent behavior of viscoelastic materials over a finite frequency band, they do not possess physically acceptable time-response functions. The paper first reviews the intimate relation between the causality of a physically realizable constitutive model and the analyticity of its frequency-response function and explains that in theory it is sufficient to conduct a nonlinear regression analysis for estimating the model parameters either on only the real part or on only the imaginary part of its frequency-response function, given that they are related with the Hilbert transform. Consequently, the resulting model-parameters are real-valued; therefore, there is no theoretical justification to conduct the nonlinear regression analysis for estimating the model parameters in the complex space. The paper concludes with an example by showing that the relaxation modulus of the complex-coefficient Maxwell model is a divergent function at all positive times; therefore it is not a physically realizable constitutive model.

description: GAO (1988) reports that approximately one-half of the eligible nonparticipants did not think they were eligible nonparticipants did not think they were eligible for the Food Stamp Program (FSP). These nonparticipants are denoted as "outreach households". Past studies (GAO, 1990. Coe) imply that programs designed to inform households of their eligibility (informational outreach programs) be directed at groups with the greatest number of outreach households. This paper illustrates that the economically efficient use of informational outreach expenditures may require concentrating outreach efforts on groups of households with fewer but more responsive uninformed nonparticipants.

description: Many farm products exhibit price variabilities over over long time intervals that range between 10 and 20 percent when measured as standard deviations of annual rates of change. Price variability is notably higher for onions, rice, wool, oats, potatoes, grapefruit, and oranges, and lower for snap beans, tobacco, green peas, milk, broccoli, processing tomatoes, and strawberries. Price variability was higher during 1977-93 than during 1949-72 for grains, soybeans, and peanuts, lower for grapes, potatoes, processing tomatoes, and hogs, and about the same for other crops and livestock. Real prices fell between 1948 and 1993 for 29 of 30 commodities studied, with poultry, eggs, wool, snap beans, grains, and cotton exhibiting the largest rates of decline.
