description: We study the relation of irregular conformal blocks with the Painlevé III$_3$ equation. The functional representation for the quasiclassical irregular block is shown to be consistent with the BPZ equations of conformal field theory and the Hamilton-Jacobi approach to Painlevé III$_3$. It leads immediately to a limiting case of the blow-up equations for dual Nekrasov partition function of 4d pure supersymmetric gauge theory, which can be even treated as a defining system of equations for both $c=1$ and $c\to\infty$ conformal blocks. We extend this analysis to the domain of strong-coupling regime where original definition of conformal blocks and Nekrasov functions is not known and apply the results to spectral problem of the Matheiu equations. Finally, we propose a construction of irregular conformal blocks in the strong coupling region by quantization of Painlevé III$_3$ equation, and obtain in this way a general expression, reproducing $c=1$ and quasiclassical $c\to\infty$ results as its particular cases. We have also found explicit integral representations for $c=1$ and $c=-2$ irregular blocks at infinity for some special points.

description: We report on the attainment of a degenerate Fermi gas of $\rm^{6}Li$ in contact with a Bose-Einstein condensate (BEC) of $^{84}$Sr. A degeneracy of $T/T_F=0.33(3)$ is observed with $1.6\times10^5$ $^{6}$Li atoms in the two lowest energy hyperfine states together with an almost pure BEC of $3.1\times10^5$ $^{84}$Sr atoms. The elastic s-wave scattering length between $^6$Li and $^{84}$Sr is estimated to be $|a_{\rm^{6}Li-\rm^{84}Sr}|=(7.1_{-1.7}^{+2.6})a_0$ ($a_0$ being the Bohr radius) from measured interspecies thermalization rates in an optical dipole trap.

 Note. The revision of American Ochterus including the description of O. bidentatus was published divided in two parts, the first published in January 1943 (SCHELL 1943a) and the second in April 1943 (SCHELL 1943b). The species was first introduced in the key, which is sufficient to make it available (ICZN 1999: Art. 13.1.1), without any mention of type specimens (SCHELL 1943a: 32), while the original description including the holotype designation appeared in the second part (SCHELL 1943b: 44). As a holotype is defined as ‘the single specimen upon which a new nominal species-group taxon is based in the original publication’ (ICZN 1999: Art. 73.1), in this case, the subsequently designated ‘holotype’ must be considered the lectotype according to ICZN (1999: Art. 74.5).

Density Power Spectrum of Compressible Hydrodynamic Turbulent Flows

Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: Turbulent flows are ubiquitous in astrophysical environments, and understanding density structures and their statistics in turbulent media is of great importance in astrophysics. In this paper, we study the density power spectra, $P_ρ$, of transonic and supersonic turbulent flows through one and three-dimensional simulations of driven, isothermal hydrodynamic turbulence with root-mean-square Mach number in the range of $1 \la M_{\rm rms} \la 10$. From one-dimensional experiments we find that the slope of the density power spectra becomes gradually shallower as the rms Mach number increases. It is because the density distribution transforms from the profile with {\it discontinuities} having $P_ρ \propto k^{-2}$ for $M_{\rm rms} \sim 1$ to the profile with {\it peaks} having $P_ρ \propto k^0$ for $M_{\rm rms} \gg 1$. We also find that the same trend is carried to three-dimension; that is, the density power spectrum flattens as the Mach number increases. But the density power spectrum of the flow with $M_{\rm rms} \sim 1$ has the Kolmogorov slope. The flattening is the consequence of the dominant density structures of {\it filaments} and {\it sheets}. Observations have claimed different slopes of density power spectra for electron density and cold H I gas in the interstellar medium. We argue that while the Kolmogorov spectrum for electron density reflects the {\it transonic} turbulence of $M_{\rm rms} \sim 1$ in the warm ionized medium, the shallower spectrum of cold H I gas reflects the {\it supersonic} turbulence of $M_{\rm rms} \sim$ a few in the cold neutral medium.

description: This study addresses the questions of future sources of technology for increasing food and agricultural production by considering the situation in Asia. This region of the world is particularly appropriate for studying these questions because of the dynamic changes in population and incomes. How much private research is there and what is it producing? Will the private sector compensate for declining public agricultural research investments in Asia? What can governments do to stimulate private research and protect farmers from harmful or defective technology? Agribusiness firm's R&D investments were evaluated in selected developing countries during 1996 and 1998 and compared with data from a similar study conducted in the mid-1980s. The largest amount of private research was in India where investment was about $55 million per year in the mid-1990s, followed by Thailand, Malaysia, and China. China's private R&D spending represents less than one one-hundredth of 1 percent of agricultural gross domestic product. In contrast, in Thailand and Malaysia, firms spent about 0.1 percent. From the mid-1980s to the mid-1990s, private sector R&D grew in real terms in the countries in our sample. However, at this rate, private research will not fill the gap needed to support rapid growth in demand for agricultural products. Foreign firms made an important contribution to private research in all of these countries. The most important policy that helped induce this growth was liberalization of industrial policy that allowed private and foreign firms to operate and expand in agricultural input industries. A second important policy was investments in public research. Patents and tax incentives seem to have had little effect so far, but could be important in the future.

description: Based on the vertex-face correspondence, we give an algebraic analysis formulation of correlation functions of the $k\times k$ fusion eight-vertex model in terms of the corresponding fusion SOS model. Here $k\in Z_{>0}$. A general formula for correlation functions is derived as a trace over the space of states of lattice operators such as the corner transfer matrices, the half transfer matrices (vertex operators) and the tail operator. We give a realization of these lattice operators as well as the space of states as objects in the level $k$ representation theory of the elliptic algebra $U_{q,p}(\hat{sl}_2)$.

Splenic contraction, catecholamine release, and blood volume redistribution during exercise in man
Creators: name: Stewart, Ian Braidwood
Publisher: name: University of British Columbia
Year: 2009

description: Numerous mammals have the ability to autotransfuse oxygenated red cells from the spleen into circulation during times of stress. This enhancement of the oxygen transport system has benefited mammals capable of heavy work (such as the thoroughbred horse, fox and greyhound) in an improved endurance performance. During times of inactivity the spleen in these mammals can sequester up to 50% of the total red cell volume. This reduces the viscosity of the blood and work of the heart. In humans the spleen is capable of storing considerably less red cells and is primarily a lymphoid organ. Although significant volume reductions have been observed with physical stress, the mechanism responsible remains unidentified and represents a primary objective of this dissertation. To determine the mechanism responsible for splenic volume reduction nine male subjects participated in a two part study. Initially they undertook three cycling bouts of 5, 10, and 15 minute duration at 60% VO^max. Spleen size and volume was assessed by scintography before and immediately following each cycling bout. Although there was a significant decrease in spleen size and volume with exercise, no significant differences were observed between the three durations. In the second part of the study the same subjects undertook an incremental ride to exhaustion. The spleen size and volume were measured prior to exercise and during one hour of passive recovery. Blood samples were collected in conjunction with spleen imaging and analyzed for plasma catecholamine concentrations. The spleen was restored to its pre-exercise value 20 minutes following the completion of exercise. The volume of the spleen during this time was inversely related to plasma catecholamine levels. It is apparent that the spleen will contract in response to an intensity dependent signal and that sympathetic stimulation, as reflected in changes in plasma catecholamine concentrations, is involved in this effect. In a simultaneous study, the effect of splenic contraction during exercise on the circulating red cell volume and indirect calculations of plasma volume change (Hb/Hct) was determined. Radio nuclide measurements of red cell and plasma volume were performed, and a blood count taken, prior to and immediately following exercise. The release of 50 mls of red cells from the spleen during exercise accounted for a 2.2% increase in the total circulating red cell volume. The indirect calculations of plasma volume were unaffected by the minor increase in peripheral hematocrit and were equivalent to radio labelled measurements. In conjunction the results of this dissertation imply that the release of red cells during exercise is not a primary function of the human spleen.
Active Cores in Deep Fields

description: Deep field observations are an essential tool to probe the cosmological evolution of galaxies. In this context, X-ray deep fields provide information about some of the most energetic cosmological objects: active galactic nuclei (AGN). Astronomers are interested in detecting sufficient numbers of AGN to probe the accretion history at high redshift. This talk gives an overview of the knowledge resulting from a highly complete soft X-ray selected sample collected with ROSAT, XMM-Newton and Chandra deep fields. The principal outcome based on X-ray luminosity functions and space density evolution studies is that low-luminosity AGN evolve in a dramatically different way from high-luminosity AGN: The most luminous quasars perform at significantly earlier cosmic times and are most numerous in a unit volume at cosmological redshift z~2. In contrast, low-luminosity AGN evolve later and their space density peaks at z~0.7. This finding is also interpreted as an anti-hierarchical growth of supermassive black holes in the Universe. Comparing this with star formation rate history studies one concludes that supermassive black holes enter the cosmic stage before the bulk of the first stars. Therefore, first solutions of the so-called hen-egg problem are suggested. Finally, status developments and expectations of ongoing and future extended observations such as the XMM-COSMOS project are highlighted.

Off-Fermi surface cancellation effects in spin-Hall conductivity of a two-dimensional Rashba electron gas

description: We calculate the spin-Hall conductivity of a disordered two-dimensional Rashba electron gas within the self-consistent Born approximation and for arbitrary values of the electron density, parametrized by the ratio $E_F /E_0$, where $E_F$ is the Fermi level and $E_0$ is the spin-orbit energy. We confirm earlier results indicating that in the limit $E_F/E_0 \gg 1$ the vertex corrections suppress the spin-Hall conductivity. However, for sufficiently low electron density such that $E_F\lesssim E_0$, we find that the vertex corrections no longer cancel contributions from the Fermi surface, and they cannot therefore suppress the spin current. This is instead achieved by contributions away from the Fermi surface, disregarded in earlier studies, which become large when $E_F\lesssim E_0$.

description: We use multi-epoch quasar spectroscopy to determine how accurately single-epoch spectroscopy can locate quasars in emission-line parameter space in order to inform investigations where time-resolved spectroscopy is not available. We explore the improvements in emission-line characterization that result from using non-parametric information from many lines as opposed to a small number of parameters for a single line, utilizing reconstructions based on an independent component analysis applied to the data from the Sloan Digital Sky Survey Reverberation Mapping project. We find that most of the quasars are well described by just two components, while more components signal a quasar likely to yield a successful reverberation mapping analysis. In single-epoch spectroscopy the apparent variability of equivalent width is exaggerated because it is dependent on the continuum. Multi-epoch spectroscopy reveals that single-epoch results do not significantly change where quasars are located in CIV parameter space and do not have a significant impact on investigations of the global Baldwin Effect. Quasars with emission line properties indicative of higher $L/L_{Edd}$ are less variable, consistent with models with enhanced accretion disk density. Narrow absorption features at the systemic redshift may be indicative of orientation (including radio-quiet quasars) and may appear in as much as 20% of the quasar sample. Future work applying these techniques to lower luminosity quasars will be important for understanding the nature of accretion disk winds.

description: Adoption of genetically engineered crops with traits for pest management has risen dramatically since their commercial introduction in the mid-1990's. The farm-level impacts of such crops on pesticide use, yields, and net returns vary with the crop and technology examined. Adoption of herbicide-tolerant cotton led to significant increase in yields and net returns, but was not associated with significant changes in herbicide use. On the other hand, increase in adoption of herbicide-tolerant soybeans led to small but significant increases in yields, no changes in net returns, and significant decreases in herbicide use. Adoption of Bt cotton in the Southeast significantly increased yields and net returns and significantly reduced insecticide use.

description: The project “Non-Dalit sensitivity for the Dalit literature amongst The students of literature in colleges of Mumbai University” is an the effort to find out the general attitude of the students of literature, across Mumbai colleges, towards Marginal Literature in general, and the Dalit literature in particular. Dalits were always marginalized ‘other’ side of the Indian society. So when they started speaking after the centuries of silence, about themselves, we have got the writings depicting assertion of human rights, self-pride, revolt against social injustice, chronicles of personal and collective suffering, and hopes and aspirations for a new society devoid of discrimination. For many years in Indian literature studies across the departments of language and literature, the syllabus, the curriculum, and the pedagogy were strongly rooted in the Western writings, aesthetics, ideologies, and sensitivities. Especially the English departments across the universities in India have prided themselves to be‘perfect’ role models in copying the exact writers, the same books, the similar novels and poetry and the similar critical theories of evaluation as their Western counterparts. For them, the literature started in England and ended also over there for all these centuries and whatever is not written in the English language had never been considered worthy of any serious consideration in a literature classroom.

description: Durch verschiedene Änderungen der Krankenhausfinanzierung sind Krankenhäuser seit 1993 einem verstärkten wirtschaftlichen Druck ausgesetzt. In einem vom Bundesministerium für Bildung und Forschung geförderten Projekt wurde untersucht, ob und in welchen Bereichen die Einführung prospektiver Finanzierungsformen zu Veränderungen in der Patientenversorgung geführt hat. Das Papier fasst die wesentlichen Ergebnisse des Forschungsprojektes zusammen. Im Mittelpunkt der Studie standen 71 qualitative Interviews mit kaufmännischen Leitungen, Ärzten und Pflegekräften in Krankenhäusern sowie externen Experten aus den Bereichen Krankenhausberatung, zuständigen Länderbehörden und Medizinischem Dienst der Krankenversicherung. Die Interviews erbrachten zahlreiche Hinweise darauf, dass patientenbezogene Entscheidungen zunehmend von ökonomischen Zielen der Krankenhäuser beeinflusst werden. Unter der Budgetdeckelung wurde die sogenannte »Punktlandung«, die möglichst exakte Erreichung der mit den Krankenkassen vereinbarten Leistungszahlen (Fallzahlen, Bettenbelegung, Erlöse etc.) zu einem zunehmend wichtigeren Ziel. Voraussetzung für eine erfolgreiche »Punktlandung« ist vor allem, dass ärztliche Entscheidungen über die Aufnahme, Indikationsstellung für Eingriffe, Verlegung oder Entlassung von Patienten im Rahmen einer medizinischen Leistungssteuerung auf die jeweiligen ökonomischen Ziele der Klinik ausgerichtet werden.

description: We treat a very crude model of an exploding star, in the weak field approximation of the Brans-Dicke theory, in a scenario that resembles some characteristics data of a Type Ia Supernova. The most noticeable feature, in the electromagnetic component, is the relationship between the absolute magnitude at maximum brightness of the star and the decline rate in one magnitude from that maximum. This characteristic has become one of the most accurate method to measure luminosity distances to objects at cosmological distances. An interesting result is that the active mass associated with the scalar field is totally radiated to infinity, representing a mass loss in the ratio of the "tensor" component to the scalar component of 1 to $(2 ω+ 3)$ ($ω$ is the Brans-Dicke parameter), in agreement with a general result of Hawking. Then, this model shows explicitly, in a dynamical case, the mechanism of radiation of scalar field, which is necessary to understand the Hawking result.

description: An average of 875,000 persons 15 years of age and older did hired farmwork each week as their primary job in 1998. An additional 63,000 people did hired farmwork each week as their secondary job. Hired farmworkers were more likely than the typical U.S. wage and salary worker to be male, Hispanic, younger, less educated, never married, and not U.S. citizens. The West (42 percent) and South (31.4 percent) census regions accounted for almost three-fourths of the hired farmworkers. The rate of unemployment in the hired farm labor force (11.8 percent) was more than double that (4.5 percent) for all wage and salary workers. Hired farmworkers were also more likely to be paid less than the minimum wage, and to be low-wage workers. Consequently, their median weekly earnings continued to be much lower than those of all wage and salary workers. However, hired farmworkers' real median weekly earnings increased 4 percent between 1990 and 1998, while earnings for all wage and salary workers increased only 2 percent. This report examines regional and structural patterns of farm labor use, and demographic and employment characteristics of hired farmworkers, using data from the 1997 Census of Agriculture and the 1998 Current Population Survey (CPS) earnings microdata file.

The full one-loop electroweak ${\cal O}(α_{ew})$ contributions to the process $e^+e^- \to t\bar t h^0$ within the minimal supersymmetric standard model (MSSM) are included. We analyze the dependence of the electroweak corrections on the MSSM parameters such as $M_{A^0}$, $\tanβ$, $M_2$, $A_{f}$, $M_{SUSY}$ and $μ$. The results show that the full one-loop electroweak radiative corrections turn out to be about -20% quantitatively and thus are important for future $e^+e^-$ linear colliders.

Novel Techniques for the Measurement of Atmospheric Organic Aerosol Physiochemical Properties

Subjects: subject: 90499 Chemical Engineering not elsewhere classified
subject: FOS: Chemical engineering

description: Atmospheric aerosols significantly impact both human health, as they increase the frequency of cardiovascular and respiratory diseases, and climate change, as they affect the Earth’s energy balance. Organic aerosol (OA) comprises a substantial fraction of atmospheric aerosol, but there is limited knowledge about its sources, chemical evolution, and physical properties, leading to considerable uncertainty in atmospheric chemical transport model predictions. The magnitude of the impact of OA on human health and climate change is strongly dependent on an improved understanding of the evolution of organic compounds in the atmosphere. Hygroscopicity, oxidation level, and volatility are three of the most crucial properties of OA because they control its atmospheric fate and climate relevance. Hygroscopicity is a measure of a compound’s ability to interact with and absorb water. The oxidation level is a useful surrogate for changes in chemical composition since the atmosphere is an oxidizing environment. Volatility determines, to a large extent, the partitioning of compounds between the particulate and vapor-phases. This work develops and tests novel techniques that can be used to measure these critical properties of OA and provide a foundation to update these properties in atmospheric models.The first part of this work describes the development and testing of a technique that quantitatively relates the hygroscopicity and oxidation level of OA components to their volatility. The technique utilizes a thermodenuder (TD) along with aerosol mass spectrometry and size-resolved cloud condensation nuclei measurements to separate the OA by volatility and characterize its hygroscopicity and oxidation level. The technique was tested with secondary OA (SOA) from the ozonolysis of α-pinene and the results indicated that the least volatile components in this SOA system were the least hygroscopic and least oxidized. The second part of this work improves the characterization of the volatility distribution of OA by combining TD and isothermal dilution measurements. The technique was tested with SOA from the ozonolysis of α-pinene and cyclohexene. The results from this work demonstrated the challenges that arise in estimating the volatility distributions of OA using thermal evaporation techniques and the benefits of combining techniques to measure properties of OA.The third part of this work combines the techniques from the first and second parts of this thesis and applies them to SOA from the ozonolysis of α-pinene, limonene, and cyclohexene. The results suggested that some OA systems have a more complex relationship between these properties than originally thought. Use of the techniques developed in this thesis to different OA, both laboratory and ambient, can supply needed parameters that can be incorporated in atmospheric models.

description: This study examines the impact of agriculture-specific and economywide institutional reform in Russia and Ukraine on the productivity and efficiency of agricultural production. Production in the agricultural sector in Russia and Ukraine has fallen since reforms began in 1992. The decline is to a certain extent an inevitable result of reform as input and output prices realign to world prices. However, some of the decline is due to incomplete agriculture-specific and economywide institutional reform. Russia and Ukraine have the potential to increase grain exports significantly if reforms are implemented: the most likely scenario projects that wheat and barley exports from Russia and Ukraine could double from current projections, reaching 21 million metric tons by 2011.
Bose-Einstein condensation and chiral phase transition in linear sigma model

description: With the linear sigma model, we have studied Bose-Einstein condensation and the chiral phase transition in the chiral limit for an interacting pion system. A $μ-T$ phase diagram including these two phenomena is presented. It is found that the phase plane has been divided into three areas: the Bose-Einstein condensation area, the chiral symmetry broken phase area and the chiral symmetry restored phase area. Bose-Einstein condensation can happen either from the chiral symmetry broken phase or from the restored phase. We show that the onset of the chiral phase transition is restricted in the area where there is no Bose-Einstein condensation.

Hydrodynamics of quantum corrections to the Coulomb interaction via the third rank tensor evolution equation: Application to the Langmuir waves and the spin-electron-acoustic waves

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: If we study the quantum effects in plasmas in terms of traditional hydrodynamics via the continuity and Euler equations we find the quantum Bohm potential and the force of spin-spin interaction. However, if we extend the set hydrodynamic equations beyond the 13-moments approximation, and include the third rank tensor evolution equation along with the pressure evolution equation, we obtain the quantum corrections to the Coulomb interaction. It is found in contrast with the fact that hydrodynamic equations for the higher rank tensors do not contain interaction in the classic plasmas studied in the selfconsistent (meanfield) approximation. Therefore, we present the quantum hydrodynamic model, where the quantum effects are studied beyond the quantum Bohm potential. Developed model is considered in two regimes: all electrons in plasmas are considered as the single fluid, and the separate spin evolution regime, where electrons with different spin projections are considered as two different fluids. To illustrate the fundamental meaning of found quantum effects we demonstrate their contribution in the spectrum of the Langmuir waves and the spin-electron-acoustic waves. It is worth to mention that the application of the pressure evolution equation ensures that the contribution of pressure in the Langmuir wave spectrum is proportional to $(3/5)v_{Fe}^{2}$, unlike $(1/3)v_{Fe}^{2}$ appearing from hydrodynamics based on the continuity and Euler equations, where $v_{Fe}$ is the Fermi velocity. Same correction corresponds on other plasmas phenomena like the speed of sound for spin-electron-acoustic waves. Moreover, it is found that novel quantum effects provide the novel wave solutions.

description: This investigation into the traceability baseline in the United States finds that private sector food firms have developed a substantial capacity to trace. Traceability systems are a tool to help firms manage the flow of inputs and products to improve efficiency, product differentiation, food safety, and product quality. Firms balance the private costs and benefits of traceability to determine the efficient level of traceability. In cases of market failure, where the private sector supply of traceability is not socially optimal, the private sector has developed a number of mechanisms to correct the problem, including contracting, third-party safety/quality audits, and industry-maintained standards. The best-targeted government policies for strengthening firms' incentives to invest in traceability are aimed at ensuring that unsafe of falsely advertised foods are quickly removed from the system, while allowing firms the flexibility to determine the manner. Possible policy tools include timed recall standards, increased penalties for distribution of unsafe foods, and increased foodborne-illness surveillance.

description: Land development in the United States is following two routes: expansion of urban areas and large-lot development (greater than 1 acre per house) in rural areas. Urban expansion claimed more than 1 million acres per year between 1960 and 1990, yet is not seen as a threat to most farming, although it may reduce production of some high-value or specialty crops. The consequences of continued large-lot development may be less sanguine, since it consumes much more land per unit of housing than the typical suburb. Controlling growth and planning for it are the domains of State and local governments. The Federal Government may be able to help them in such areas as building capacity to plan and control growth, providing financial incentives for channeling growth in desirable directions, or coordinating local, regional, and State efforts.

description: We present distance measurements to 71 high redshift type Ia supernovae discovered during the first year of the 5-year Supernova Legacy Survey (SNLS). These events were detected and their multi-color light-curves measured using the MegaPrime/MegaCam instrument at the Canada-France-Hawaii Telescope (CFHT), by repeatedly imaging four one-square degree fields in four bands. Follow-up spectroscopy was performed at the VLT, Gemini and Keck telescopes to confirm the nature of the supernovae and to measure their redshift. With this data set, we have built a Hubble diagram extending to z=1, with all distance measurements involving at least two bands. Systematic uncertainties are evaluated making use of the multi-band photometry obtained at CFHT. Cosmological fits to this first year SNLS Hubble diagram give the following results : Omega_M = 0.263 +/- 0.042(stat) +/- 0.032(sys) for a flat LambdaCDM model; and w = -1.023 +/- 0.090(stat) +/- 0.054(sys) for a flat cosmology with constant equation of state w when combined with the constraint from the recent Sloan Digital Sky Survey measurement of baryon acoustic oscillations.

description: We study the scattering amplitudes in the N=2 minimal string or equivalently in the N=4 topological string on ALE spaces. We find an interesting connection between the tree level amplitudes of the N=2 minimal string and those of the (1,n) minimal bosonic string. In particular we show that the four and five-point functions of the N=2 string can be directly rewritten in terms of those of the latter theory. This relation offers a map of physical states between these two string theories. Finally we propose a possible matrix model dual for the N=2 minimal string in the light of this connection.

CHANGES IN AGRICULTURAL MARKETS IN TRANSITION ECONOMIES

description: Economic reform in the transition economies of the former Soviet bloc has transformed the volume and mix of these economies' agricultural production, consumption, and trade. Output drops in most countries have ranged from 25 to 50 percent. The livestock sector has been hit particularly hard, all but eliminating U.S. grain exports to the region. This report concludes that the output decline has been an inevitable part of market reform and that the main goal of agricultural policy in the transition economies should not be to return output to pre-reform levels but to increase the productivity of input use. Although reform has created a food security problem in some countries, the cause of the problem is not insufficient food supplies, but rather inadequate access to food by segments of the population and regions within countries.
