description: Instant Messaging (IM) applications like Telegram, Signal, and WhatsApp have become extremely popular in recent years. Unfortunately, such IM services have been targets of continuous governmental surveillance and censorship, as these services are home to public and private communication channels on socially and politically sensitive topics. To protect their clients, popular IM services deploy state-of-the-art encryption mechanisms. In this paper, we show that despite the use of advanced encryption, popular IM applications leak sensitive information about their clients to adversaries who merely monitor their encrypted IM traffic, with no need for leveraging any software vulnerabilities of IM applications. Specifically, we devise traffic analysis attacks that enable an adversary to identify administrators as well as members of target IM channels (e.g., forums) with high accuracies. We believe that our study demonstrates a significant, real-world threat to the users of such services given the increasing attempts by oppressive governments at cracking down controversial IM channels. We demonstrate the practicality of our traffic analysis attacks through extensive experiments on real-world IM communications. We show that standard countermeasure techniques such as adding cover traffic can degrade the effectiveness of the attacks we introduce in this paper. We hope that our study will encourage IM providers to integrate effective traffic obfuscation countermeasures into their software. In the meantime, we have designed and deployed an open-source, publicly available countermeasure system, called IMProxy, that can be used by IM clients with no need for any support from IM providers. We have demonstrated the effectiveness of IMProxy through experiments.

description: Taiwan, in just the past two years, lifted quoto restrictions on wheat imports and lowered tariff barriers. These changes along with the antitrust movement and severe overcapacity will be the catalysts for tremendous structural changes in the way wheat millers compete for domestic market share and contracts for flour. The purpose of this study was to examine the impact of liberalization on the Taiwan milling industry.

description: The most important cool season grain legumes (dry pea, chickpea, broad bean, lentil, lupins, grass pea and common vetch) are widely grown in many parts of the world. The aim of the current study was to test some of them under the drought-prone area of Sadovo (south-central region of Bulgaria) and to evaluate their adaptability based on physiological and agro-biological traits. The investigation was carried out at the experimental field of IPGR including several local accessions of white lupin (Lupinus albus L.), chickpea (Cicer arietinum L.) and grass pea (Lathyrus sativum L.). The chlorophyll content index of the leaves, used as criteria for drought tolerance, was measured by portable CCM 200 plus- Chlorophyll Content Meter. The assessment of agro-biological traits was performed according to the International Descriptor for each crop. Under the drought stress conditions the highest value of the chlorophyll content index was observed in three lupin accessions (BGR 6341, BGR3080, BGR3085), in two from chickpea (BGR 40417 and B9E0149) and in four from grass pea (BGR 40415, BGR 4835, BGR4847, BGR4834). The highest yield potential was established in two lupin (BGR 6341 and BGR 3084), two chickpea accessions (BGR 23151 and B9E0149) and three grass pea (BGR4832 and BGR40415). The selected accessions were included in the list for further investigations concerning drought tolerance and maintenance of relatively high yield potential under drought stress conditions.

description: The value of sportfishing in the Snake River Basin in Central Idaho was measured using a two-stage/disequilibrium travel model. The two-stage/disequilibrium model does not require monetization of recreationists? travel time as required of traditional equilibrium labor market travel cost models. The model was estimated using Poisson regression, appropriate for count data when over-dispersion is absent, and adjusted for endogenous stratification (self selection bias) . Contrary to expectations that anglers living close to the sites with low values would be over represented in the sample, the endogenous stratification adjustment caused estimated consumers surplus to decline from $42 per person per trip before adjustment for endogenous stratification to $35 after adjustment. The average number of sportfishing trips per year was 6.72, resulting in an average annual willingness-to-pay of $236 per year per angler.

description: The structural property of liquid cesium is investigated in the temperature range 900 K to 1900 K by application of semiempirical effective Lennard-Jones (8.5-4) pair potential function and employing Gillan s algorithm to solve Percus-Yevick equation. The potential function has been derived accurately by application of cohesive energy density in a wide range of pressure-density-temperature () data including data at the proximity of absolute zero temperature. The method is very much responsive to the liquid dynamics and leads to indication of three distinct ranges of metal, nonmetal, and metal-nonmetal transition states. The resulted pair correlation functions are well compared with the reported experimental and first-principle molecular dynamic. The calculated coordination numbers in the liquid range are in agreement with experiment particularly at low temperatures, though it is singular at about 1400 K. This observation is similar to the change from one liquid structure to another one and is verified by heights of the first peak of experimental pair correlation function as a function of temperatures. At T=973 K, the position of the first peak (r=7.27 A) is in agreement well with experimental (r=5.31 A) and with the first-principle DFT molecular dynamics (r=5.24 A).

The role of wood in headwater channels and short-term channel responses to harvesting of second growth riparian forests in Southwestern British Columbia
Creators: name: Winfield, Nicholas A.
Publisher: name: University of British Columbia
Year: 2009

description: A watershed-scale experiment was set up at Malcolm Knapp Research Forest in southwestern British Columbia to study the effectiveness of variable width riparian reserves on physical and biological components of small streams. One component of the experiment was an investigation into the influence of large woody debris (LWD) on the morphology of 12 headwater streams. Pools were selected as a key response variable as they are considered a limiting factor in small streams and serve an important role as a low-flow refuge habitat for fish. All pool forming LWD was inventoried, and pool volumes and percentage of fine sediments in pools were measured before logging (summer 1998) and after logging (summer 1999). Subwatershed pairs were determined based on known and predicted peak stream powers. This enabled within-group analysis of channel response to different riparian treatments. Detailed channel assessments and surveys were undertaken in consecutive years to monitor channel morphology changes over time. LWD was the dominant pool-forming element for all streams regardless of channel type. Linear regression analysis found that the variance in pool volume explained by LWD in three step-pool streams and one riffle-pool stream ranged from 15-50%. LWD did not explain the variance in pool volume in the remaining five perennial streams, including two riffle-pool reaches and three step-pool reaches. Removal of old growth trees prior to the 1920s likely explains the low volume of wood and corresponding low pool volumes in these two riffle-pool channels where LWD is expected to play an important role in pool formation. Target levels of LWD for smaller size classes of fish-bearing streams were developed based on relationships between LWD volume and pool volume and predicted pool spacing for different channel types. Comparison of channel response to riparian harvesting based on peak stream power found that streams with low stream power with clear-cut treatments showed reductions in pool volume, specifically reductions in pool size. These streams had insufficient stream power to remove sediment and debris deposited during logging as compared to streams with high stream power which were able to remove sediments.

description: The genetic traits that an Angus bull possesses convey the reproductive and economic value of the animal to potential buyers. This paper examines and draws comparisons between the value of actual production weights and production EPDs, while also establishing values for ultrasound EPDs. Results indicate that only one EPD, birth weight, was valued by buyers more than its corresponding actual weight, though actual weights and EPDs significantly impacted price. Ultrasound EPDs were also found to be significant, suggesting buyers of Angus bulls consider carcass information when purchasing bulls.

description: The concept of preconditioning calves has been around for a long time, yet adoption of the practice has been slow. Current trends in the beef industry likely will increase interest in preconditioning programs. This research estimates premiums received for preconditioned calves and the expected returns from a preconditioning program. Preconditioned calves sold in the fall received a premium of approximately $4.50-$5.50/cwt relative to non-preconditioned calves. Premiums were lower for calves sold in the winter, heavier calves, and when cattle markets were strong. Based on a 45-day post-weaning preconditioning program, cow-calf producers can increase returns about $14/head compared to selling calves at weaning.
Numerical Study of the Oscillatory Convergence to the Attractor at the Edge of Chaos

description: This paper compares three different types of ``onset of chaos'' in the logistic and generalized logistic map: the Feigenbaum attractor at the end of the period doubling bifurcations; the tangent bifurcation at the border of the period three window; the transition to chaos in the generalized logistic with inflection 1/2 ($x_{n+1} = μx_{n}^{1/2}$), in which the main bifurcation cascade, as well as the bifurcations generated by the periodic windows in the chaotic region, collapse in a single point. The occupation number and the Tsallis entropy are studied. The different regimes of convergence to the attractor, starting from two kinds of far-from-equilibrium initial conditions, are distinguished by the presence or absence of log-log oscillations, by different power-law scalings and by a gap in the saturation levels. We show that the escort distribution implicit in the Tsallis entropy may tune the log-log oscillations or the crossover times.

title: Not just fat : investigating novel physiological state biomarkers in cetacean blubber
Creators: name: Kershaw, Joanna
Publisher: name: University of St Andrews
Year: 2019

description: Despite its importance as a predictor of fitness, no consensus has been reached about how to assess the nutritive body condition of free-ranging cetaceans. Standard indices of condition used in terrestrial ecology were assessed in cetaceans using data and samples from stranded animals. The most appropriate morphometric indices were identified as mass/length2 and girth/length (where mass data were unavailable). Blubber thickness, and blubber lipid content were poor indicators of condition. Variation in lipid content suggested that there may be tradeoffs occurring between different blubber functions involved in energy storage, controlling buoyancy, and preserving thermoregulatory properties in species with different life-history strategies. Novel blubber biomarkers of physiological state were investigated as objective and widely applicable tools for estimating body condition. Blubber cortisol concentrations were negatively correlated with morphometric indices of condition in stranded animals from two cetacean families. Blubber cortisol concentrations were thus identified as a candidate biomarker. When applied to a 13-year dataset of biopsy samples from female humpback whales (Megaptera novaeangliae), cortisol concentrations showed significant inter-annual variation. Concentrations were weakly correlated with annual pregnancy rates. High individual variability in blubber cortisol concentrations was likely a result of the multi-functional nature of cortisol. Cortisol concentrations thus probably provide a ‘snap shot’ of the metabolic state of the tissue when sampled. A proteomic approach was developed to extract and identify proteins in blubber. A range of proteins involved in numerous metabolic processes and pathways were identified. These proteins likely capture the range of physiological processes experienced by individuals at the time of sampling. This new proteomic approach will help to assign novel functions to marine mammal blubber in keeping with current understanding of the multi-functional role of adipose tissue as an endocrine organ in mammals. It will also allow the future development of protein biomarkers of health and physiological state.

The role of ActA in peptidoglycan remodelling of Listeria monocytogenes
Creators: name: Ohoud S. Al-Humaidan
Publisher: name: University of Leicester
Year: 2021
Subjects: Uncategorized

description: Listeria monocytogenes is a food-borne bacterial pathogen, which occupies different ecolo-gical niches and is responsible for a number of serious infections in humans.L. monocytogenes has many virulence factors that enable its replication in macrophages and escape from the phagolysosome to the cytoplasm. The actin-assembly inducing protein (ActA) is one of the major virulence factors, which mediates actin polymerization, and thereby aids the intracellular motility and cell-to-cell spread, which is critical for L. monocytogenes pathogenesis. Recently, the ActA protein has been shown to regulate peptidoglycan (PG) biosynthesis during the replication of L. monocytogenes in macrophages. However, the exact mechanism for this phenomenon is unknown. The central hypothesis of the present study is that ActA possesses PG cleaving activity which controls PG biosynthesis and remodelling.ActA is a secreted protein which consists of N-terminal, central and C-terminal domains. Three recombinant His-tagged proteins representing different domains of ActA have been successfully expressed and purified in Escherichia coli C41(DE3). Using a range of approaches, I have shown that the N-terminal domain of ActA has PG cleaving activity. To identify putative catalytic residues, 14 site-directed mutants where acidic residues were replaced with alanine have been generated. None of the mutants resulted in the complete elimination of cleaving activity; however, there was a reduction in activity for two mutants, the MUT 3 and MUT6 proteins. Proteomic analysis revealed the presence of ActA in the culture supernatant and the cell envelope fractions of L. monocytogenes, further supporting the idea that the role of this protein is in cell wall remodelling. ActA has 50 % homology with RpfA, one of the resuscitation-promoting factors found in Mycobacteria. However, domain swapping experiments in which the active domain in RpfA was replaced with the N-terminal domain of ActA, showed limited complementation of the triple Rpf mutant phenotype.The identification of peptidoglycan cleaving activity of the N- terminal domain in ActA from L. monocytogenes would offer a novel opportunity to target and combat the virulence of this significant pathogen.

description: This study estimates the price determinants of show quality Quarter Horses sold at auction. Several characteristics including genetic and physical traits, the quality of pedigree, and the sale order affect price. Sale price is positively affected by a strong performance record of the horse as well as the performance record of the horse's offspring. A common practice at horse auctions is for the seller to reject the final bid offered and not sell the horse. The market prices predicted by the model for these horses indicate that they are not undervalued by the final bids, based on their characteristics.

description: Most of the existing approaches for person re-identification consider a static setting where the number of cameras in the network is fixed. An interesting direction, which has received little attention, is to explore the dynamic nature of a camera network, where one tries to adapt the existing re-identification models after on-boarding new cameras, with little additional effort. There have been a few recent methods proposed in person re-identification that attempt to address this problem by assuming the labeled data in the existing network is still available while adding new cameras. This is a strong assumption since there may exist some privacy issues for which one may not have access to those data. Rather, based on the fact that it is easy to store the learned re-identifications models, which mitigates any data privacy concern, we develop an efficient model adaptation approach using hypothesis transfer learning that aims to transfer the knowledge using only source models and limited labeled data, but without using any source camera data from the existing network. Our approach minimizes the effect of negative transfer by finding an optimal weighted combination of multiple source models for transferring the knowledge. Extensive experiments on four challenging benchmark datasets with a variable number of cameras well demonstrate the efficacy of our proposed approach over state-of-the-art methods.

description: The extended Airy kernel describes the space-time correlation functions for the Airy process, which is the limiting process for a polynuclear growth model. The Airy functions themselves are given by integrals in which the exponents have a cubic singularity, arising from the coalescence of two saddle points in an asymptotic analysis. Pearcey functions are given by integrals in which the exponents have a quartic singularity, arising from the coalescence of three saddle points. A corresponding Pearcey kernel appears in a random matrix model and a Brownian motion model for a fixed time. This paper derives an extended Pearcey kernel by scaling the Brownian motion model at several times, and a system of partial differential equations whose solution determines associated distribution functions. We expect there to be a limiting nonstationary process consisting of infinitely many paths, which we call the Pearcey process, whose space-time correlation functions are expressible in terms of this extended kernel.

description: The lifelong efforts of Paul A. M. Dirac were to construct localized quantum systems in the Lorentz covariant world. In 1927, he noted that the time-energy uncertainty should be included in the Lorentz-covariant picture. In 1945, he attempted to construct a representation of the Lorentz group using a normalizable Gaussian function localized both in the space and time variables. In 1949, he introduced his instant form to exclude time-like oscillations. He also introduced the light-cone coordinate system for Lorentz boosts. Also in 1949, he stated the Lie algebra of the inhomogeneous Lorentz group can serve as the uncertainty relations in the Lorentz-covariant world. It is possible to integrate these three papers to produce the harmonic oscillator wave function which can be Lorentz-transformed. In addition, Dirac, in 1963, considered two coupled oscillators to derive the Lie algebra for the generators of the $O(3,\,2)$ de Sitter group, which has ten generators. It is proven possible to contract this group to the inhomogeneous Lorentz group with ten generators, which constitute the fundamental symmetry of quantum mechanics in Einstein's Lorentz-covariant world.

Risk and Uncertainty

description: In this paper we attempt an intertemporal study of risk management decisions for wheat growers in the Pacific Northwest. We apply a generalized expected utility model (GEU) to examine the farmers' optimal choices of hedging ratios and crop insurance coverage levels in the presence of government payment programs in a multi-period production environment. A stochastic trend model is used to identify the long-term time series patterns of annual wheat yields, cash prices, and futures prices from two counties in Washington. The fitted models are then used as the base for yield and price simulation over the next five years. The stochastic dynamic optimization problem is solved numerically based on simulated data. The optimal solutions indicate that the GEU model is feasible in modeling farmers' intertemporal decisions regarding risk management. The comparison between GEU model and some commonly used expected utility models further implies the advantage of the GEU model in being flexible to specify farmers' intertemporal preferences separately and completely.

The temperature dependence of the harmonics of the susceptibility have been numerically simulated with these two models, and we studied them as a function of the frequency, in terms of Cole-Cole plots. From our analysis we show that it is possible to distinguish between the two different phases, because of their clear differences in the Cole-Cole plots behaviour with the frequency.

description: Native American obesity and the associated health conditions are generally thought to result in part from a genetic predisposition to overeating fats and carbohydrates, called the "thrifty gene." Although coined by nutritional scientists, this study maintains the origin of the thrifty gene lies in economics. Apparently harmful overconsumption and addiction constitute economically rational behavior if the increment to current utility from adding to one's stock of "consumption capital" is greater than the present value of utility lost in the future due to ill health and the costs of withdrawal. Tests of these conditions for such "rational addiction" are conducted using two-stage household production approach. The results obtained by estimating this model in a panel of Native and non-Native supermarket scanner data show that both Natives and non-Natives tend to be inherently forward-looking in their nutrient choices, but Natives tend to have far higher long-run demand elasticities for carbohydrates compared to non-Natives. Consequently, reductions in real food prices over time, primarily among foods that are dense in simple carbohydrates, leads Native Americans to over-consume potentially harmful nutrients relative to their traditional diet.

description: The effect of inhomogeneous coupling between three-level atoms and external light fields is studied in the electromagnetically induced transparency (EIT) quantum memory techqnique. By introducing a subensemble-atomic system to deal with present inhomogeneous coupling case, we find there is a non-symmetric dark-state subspace (DSS) that allows the EIT quantum memory technique to function perfectly. This shows that such memory scheme can work ideally even if the atomic state is very far from being a symmetric one.

These two Laplacian fractals appear different to the eye; in addition, viscous fingering is grown in parallel and the aggregates by a serial algorithm. Nevertheless, the data strongly indicate that these two fractal growth patterns are in the same universality class.

description: Asparagus harvesting methods and strategies have remained unchanged since inception in Washington. A bioeconomic model was developed to determine the profit optimizing frequency of harvesting for manual and mechanical harvesting techniques. The mechanical harvester is economically viable if the harvester cuts 72.3 percent and 73.55 percent of what a hand crew would cut for process and fresh utilization, respectively. The results indicate that decreasing the frequency of harvest increases profit for asparagus used in processing. This research is the first attempt to address the problem of asparagus harvesting with a bioeconomic model.

description: Electron spin echo envelope modulation (ESEEM) has been observed for the first time from a coupled hetero-spin pair of electron and nucleus in liquid solution. Previously, modulation effects in spin echo experiments have only been described in liquid solutions for a coupled pair of homonuclear spins in NMR or a pair of resonant electron spins in EPR. We observe low-frequency ESEEM (26 and 52 kHz) due to a new mechanism present for any electron spin with S>1/2 that is hyperfine coupled to a nuclear spin. In our case these are electron spin (S=3/2) and nuclear spin (I=1) in the endohedral fullerene N@C60. The modulation is shown to arise from second order effects in the isotropic hyperfine coupling of an electron and 14N nucleus.

description: This research report by Eilleen T. Kennedy is part of a major IFPRI effort to assess the effects of the commercialization of agriculture on production, consumption, and nutritional status of rural people in Africa, Asia, and Central America countries. It reports on the continuation of survey work first undertaken at the request of the government of Kenya in 1983. The original survey work was analyzed in Research Report 63, Incomes and Nutrition Effects of the Commercialization of Agriculture in Southwestern Kenya. The follow-up study described in this report a rare opportunity to examine longitudinal data on a group of farmers in three periods: before they entered a contract arrangement for growing a commercial crop- sugarcane; during the period before they harvested their first sugar crop; and after the harvest. Moreover, the study includes landless, merchant, and nonsugar-growing farm households, as well as the contract sugarcane growers at various stages in the commercialization of agriculture. This longer-term analysis confirms the findings of the earlier study that commercialization has positive benefits stemming from increased household incomes and has no negative effects on the nutritional status of children in sugarcane growing households. It is also clear, however, that commercialization is not a cure-all for childhood illness and malnutrition. Increased incomes must be accompanied by improved health and sanitation facilities if they are to have a major effect in reducing such illness and malnutrition. Other recently published research reports in the commercialization of agriculture series include Cooperative Dairy Development in Kamaraka, India: An Assessment, Research Report 64: Nontraditional Export Crops in Guatemala: Effects on Production, Income, and Nutrition, Research Report 73; and Irrigation Technology and commercialization of Rice in the Gambia: Effects on income and Nutrition, Research Report 75.

description: In this paper, we discuss the weak gravitational lensing in the context of stringy black holes. Initially, we examine the deflection angle of photon by charged stringy black hole. For this desire, we compute the Gaussian optical curvature and implement the Gauss-Bonnet theorem to investigate the deflection angle for spherically balanced spacetime of stringy black hole. We also analyze the influence of plasma medium in the weak gravitational lensing for stringy black hole. Moreover, the graphical impact of impact parameter $b$ , black hole charge $Q$ on deflection angle by charged stringy black hole has been studied in plasma as well as non-plasma medium.

On the size distribution of sunspot groups in the Greenwich sunspot record 1874-1976

description: We investigate the size distribution of the maximum areas and the instantaneous distribution of areas of sunspot groups using the Greenwich sunspot group record spanning the interval 1874-1976. Both distributions are found to be well described by log-normal functions. Using a simple model we can transform the maximum area distribution into the instantaneous area distribution if the sunspot area decay rates are also distributed log-normally. For single-valued decay rates the resulting snapshot distribution is incompatible with the observations. The current analysis therefore supports the results of Howard (1992) and MartinezPillet (1993). It is not possible to distinguish between a linear and a quadratic decay law, however, with the employed data set.

description: In 1982 Dominga Cavallo and Yair Mundlak received an award for quality of research discovery from the American Agriculture Economics Association for IFPRI Research Report 36, Agriculture and Economic Growth in an Open Economy: The Case of Argentina. The research was sponsored jointly by IFPRI and the Instituto de Estudios Economicos Sobre la Realidad Argentina y Latinoamericana (IEERAL) of the Fundacion Mediteranea, and it in turn built on earlier prize-winning research by Mundlak, presented in Research Report 6, Intersectoral Factor Mobility and Agricultural Growth. The model developed for the study makes it possible to explore the effects of policies directed at agriculture as well as general macro and trade policies, taking into account interaction with other sectors of the economy. IFPRI and IEERAL have again cooperated in sponsoring this research, which is and expansion of the earlier work. Yair Mundlak, Dominga Cavallo, and Roberto Domenech apply the model to a larger body of data, extending the time period coverted from 1946-73 to 1913-84 in order to measure the effects of Argentina’s macro and trade policies during the Great Depression and the volatile 1970s and 1980s. In this segment of the research, government is presented as a separate sector. Thus the effect of government actions, such as consumption, investment, the deficit, and its financing, in the private sector are evaluated. The message that emerged for agriculturally based economies is clear. Inward-looking policies that gave high protection to the industrial sector and taxed agricultural exports, reinforced by expansionary macroeconomic policies, severely restricted the overall growth of Argentina. This study on Argentina is part of IFPRI’s research program on trade and macroeconomic linkages and agricultural growth. Other country studies include Chile, Colombia, Nigeria, Pakistan, the Philippines, and Thailand.

description: A bio-grouting method is utilising the interdisciplinary knowledge to alter sand engineering properties in the subsurface by turning it from the soil like into sandstone like. Bio-grouting utilises soil microbial processes to precipitate calcium carbonate into the soil matrix, which binds soil particles together to increase strength and stiffness of soil. Bio-grouting involves numerous biogeochemical effects, making the process as a completely complex to understand. In this thesis, optimising of the bio-grouting process treated coarser materials, microstructure tracing and a sand column application have been conducted. The outcomes of this thesis establish bases to scale up bio-grouting process from bench scale to field scale.
Correlating the Antisymmetrized Geminal Power Wave Function

description: Strong pairing correlations are responsible for superconductivity and off-diagonal long range order in the two-particle density matrix. The antisymmetrized geminal power wave function was championed many years ago as the simplest model that can provide a reasonable qualitative description for these correlations without breaking number symmetry. The fact remains, however, that the antisymmetrized geminal power is not generally quantitatively accurate in all correlation regimes. In this work, we discuss how we might use this wave function as a reference state for a more sophisticated correlation technique such as configuration interaction, coupled cluster theory, or the random phase approximation.
An analytical study of resonant transport of Bose-Einstein condensates

description: We study the stationary nonlinear Schrödinger equation, or Gross-Pitaevskii equation, for a one--dimensional finite square well potential. By neglecting the mean--field interaction outside the potential well it is possible to discuss the transport properties of the system analytically in terms of ingoing and outgoing waves. Resonances and bound states are obtained analytically. The transmitted flux shows a bistable behaviour. Novel crossing scenarios of eigenstates similar to beak--to--beak structures are observed for a repulsive mean-field interaction. It is proven that resonances transform to bound states due to an attractive nonlinearity and vice versa for a repulsive nonlinearity, and the critical nonlinearity for the transformation is calculated analytically. The bound state wavefunctions of the system satisfy an oscillation theorem as in the case of linear quantum mechanics. Furthermore, the implications of the eigenstates on the dymamics of the system are discussed.

description: Survey data from a USDA-funded multi-state longitudinal project revealed a paradox where rural low-income families from states considered prosperous were persistently more food insecure than similar families from less prosperous states. An examination of quantitative and qualitative data found that families in the food insecure states were more likely to experience greater material hardship and incur greater housing costs than families in the food secure states. Families in the food insecure states, however, did not have lower per capita median incomes or lower life satisfaction than those in the food secure states. A wide range of strategies to cope with food insecurity reported by families in both food insecure and food secure states was examined using the Family Ecological Systems Theory. Families in the food insecure states used several risky consumption reduction strategies such as curbing their appetite and using triage. Families in the food secure states, on the other hand, employed positive techniques involving their human capital.
