description: The recent wide fluctuations in diesel fuel costs and subsequent trucking costs has raised speculation within the produce industry of potential structural shifts in the location of production. Recent increases in demand for local produce seem to further support speculation toward this end. A component pricing model is used to actually examine the impact of fuel prices on farm gate and retail produce prices for strawberries, lettuce, and potatoes. The study finds that distribution costs, while significantly increasing in absolute value, have surprisingly little contribution to changes in retail prices even in markets distant to the primary production regions. These results suggest that factors other than lower distribution costs for local produce will ultimately need to drive the supply for these products.
Improving evolvability of operating systems with AspectC
Creators: name: Coady, Monica Yvonne
Publisher: name: University of British Columbia
Year: 2009

description: Operating system code is complex. But, while substantial complexity is inherent to this domain, other complexity is caused by modularity problems. The implementation of certain key system concerns seems to defy traditional modular boundaries and impede evolution. From OS/360 to Windows NT, systems suffer from unintentional interactions between modules [Lehman and Belady 1985] and require developers to be intimately familiar with implicit patterns of interaction between subsystems [Vogels 1999]. The thesis of this work is that aspect-oriented programming (AOP) can be used to improve evolution in operating system code by improving modularity. Specifically, AOP can alleviate modularity problems associated with concerns that are inherently crosscutting - no single modular decomposition can localize both the crosscutting concern and the concerns it crosscuts. Better modularization of crosscutting concerns requires that their implementation be localized, their interaction with the parts of the system they crosscut be explicit, and their internal structure be clear. By accomplishing these three things, AOP can provide better structural support for evolution. The first part of the thesis provides a case study comparing modularity involving three crosscutting concerns in the original versus aspect-oriented implementation within the FreeBSD operating system [Lehey 1999]. This comparison highlights specific improvements in modularity of both the crosscutting concerns and the concerns that are crosscut, or interacting concerns, in the AOP implementation. The second part of the thesis surveys evolutionary changes the three crosscutting concerns underwent between releases 2.2 (1997), 3.3 (1999) and 4.4 (2001) of FreeBSD, and identifies some of the specific impediments the original implementation poses with respect to evolution. A case study of the impact of these same evolutionary changes on the aspect-oriented implementation highlights improvements in locality of change afforded by the AOP implementation, and the ways in which improvements in modularity persist across the versions. The final part of the thesis presents inferences and generalizations based on the results of the case studies. We infer from the case studies that AOP can be used to improve evolvability of the three crosscutting concerns and their interacting concerns in three versions of FreeBSD, without harming non-interacting concerns. We then generalize these modularity benefits to more concerns, more systems, and more versions, and infer support for our main claim - that aspect-oriented programming can be used to improve evolvability of operating system code by providing better modularity of crosscutting concerns and their interacting concerns, without harming non-interacting concerns.

description: The recent rapid increase in commodity prices is not an unique event. It has happened several times in the past. Commodity prices have always dropped, returning to a more normal level. Production costs, on the other hand, follow commodity prices up but do not follow them down. Net farm income has increased rapidly in most commodity sectors of agriculture. However, production costs have increased substantially during the past few years. Those cost increases will reduce net farm incomes in the future if commodity prices do not continue to increase.

description: Agricultural producer groups have stressed for years the need for a disaster title in the farm bill. In the 2008 Farm Bill, the Supplemental Revenue Assistance Program (SURE) was included to address that need. Previously, producers had to convince Washington to fund ad hoc and emergency disaster declarations in times of low crop returns. This study reviews the SURE program and estimates the effectiveness of the program for North Dakota farmers. The SURE program replaces disaster funding; however it also probably prevents additional assistance under extra ordinary conditions.

description: Morphology of metal thin layers deposited on polished surfaces of LiNbO$_3$ crystal with dissimilar electric charges has been studied using various methods of vacuum evaporation. The principal goal of the work is to optimizemethods of thin metal coating deposition applied to polar surfaces of LiNbO$_3$ crystal. The conducted research has demonstrated that Cr deposition on LiNbO$_3$ crystal faces is characterized by dissimilar polarity results in growth difference conditions of Cr films. The principal role here is played by the sign of the electric charge on the crystal surface along with the type (thermal or magnetron) and conditions observed during sputtering (deposition rate, substrate temperature etc).

description: Including the orbital off-diagonal spin and charge condensates in the self consistent determination of magnetic order within a realistic three-orbital model for the $4d^4$ compound $\rm Ca_2 Ru O_4$, reveals a host of novel features including strong and anisotropic spin-orbit coupling (SOC) renormalization, coupling of strong orbital magnetic moments to orbital fields, and a magnetic reorientation transition. Highlighting the rich interplay between orbital geometry and overlap, spin-orbit coupling, Coulomb interactions, tetragonal distortion, and staggered octahedral tilting and rotation, our investigation yields a planar antiferromagnetic (AFM) order for moderate tetragonal distortion, with easy $a-b$ plane and easy $b$ axis anisotropies, along with small canting of the dominantly $yz,xz$ orbital moments. With decreasing tetragonal distortion, we find a magnetic reorientation transition from the dominantly planar AFM order to a dominantly $c$ axis ferromagnetic (FM) order with significant $xy$ orbital moment.

One-dimensional annihilating random walk with long-range interaction

Publisher: name: arXiv
Year: 2020
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study the annihilating random walk with long-range interaction in one dimension. Each particle performs random walks on a one-dimensional ring in such a way that the probability of hopping toward the nearest particle is $W= [1 - ε(x+μ)^{-σ}]/2$ (the probability of moving away from its nearest particle is $1-W$), where $x$ is the distance from the hopping particle to its nearest particle and $ε$, $μ$, and $σ$ are parameters. For positive (negative) $ε$, a particle is effectively repulsed (attracted) by its nearest particle and each hopping is generally biased. On encounter, two particles are immediately removed from the system. We first study the survival probability and the mean spreading behaves in the long-time limit if there are only two particles in the beginning. Then, we study how the density decays to zero if all sites are occupied at the outset. We find that the asymptotic behaviors are classified by seven categories: (i) $σ>1$ or $ε=0$, (ii) $σ= 1$ and $2ε> 1$, (iii) $σ=1$ and $2ε= 1$, (iv) $σ= 1$ and $2ε< 1$, (v) $σ<1$ and $ε> 0$, (vi) $σ= 0$ and $ε<0$, and (vii) $0 < σ<1$ and $ε<0$. The asymptotic behaviors in each category are universal in the sense that $μ$ (and sometimes $ε$) cannot affect the asymptotic behaviors.

description: We show that a solution to the the coincidence problem can be found in the context of a generic class of dark energy models with a scalar field, $ϕ$, with a linear effective potential $V(ϕ)$. We determine the fraction, $f$, of the total lifetime of the universe, $t_U$, which lies within the interval $[t_0-Δt_A,t_0+ Δt_A]$, where $t_0$ is the age of the universe at the present time, $Δt_A \equiv t_0-t_A$ and $t_A$ is the age of the universe when it starts to accelerate. We find that if we require $f$ to be larger than 0.1 (0.01) then $1+ω_{\phi0} \gapp 2 \times 10^{-2}$ ($1 \times 10^{-3}$), where $ω_ϕ \equiv p_ϕ/ρ_ϕ$. These results depend mainly on the linearity of the scalar field potential for $-V(ϕ_0) \lapp V(ϕ) \lapp V(ϕ_0)$ and are weakly dependent on the specific form of $V(ϕ)$ outside this range. We also show that if $ω_{\phi0}$ is close to -1 then $ω_{\phi0}+1 \sim 1.6 ({\tilde ω}_ϕ+1)$, where ${\tilde ω}_ϕ$ is the weighted average value of $ω_ϕ$ in the time interval $[0,t_0]$. We independently confirm current observational constraints on this class of models which give $ω_{\phi0} \lapp -0.6$ and $t_U \gapp 2.4 t_0$ at the $2 σ$ level.

Can Early Type Galaxies Evolve from Fading the Disks of Late Types?

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We examine whether early-type galaxies in clusters may have evolved from later types by the fading of their disks (e.g., as a result of ram-pressure stripping or strangulation) or by enhancement of the bulge luminosity (e.g., due to tidal interactions and mergers). For this purpose, we compare the bulge and disk luminosities of early- and late-type galaxies and of galaxies at different radial distances from the cluster center. We find that, in order for early-type galaxies, including S0s, to have evolved from late-type galaxies, their bulge luminosities must have been physically enhanced. Disk fading models cannot explain the differences observed. We then show that galaxy bulges are systematically brighter at small projected distances from the cluster center, while disk luminosities are uncorrelated with cluster-centric distance. Our results suggest that bulge enhancement, not disk fading, distinguishes early from late types and is thus at least partially responsible for the morphology-environment relation of bright cluster galaxies.

description: We review the implications of the 2007 Farm Bill for the risk management dimensions of U.S. agriculture and policy. Legislative proposals suggest significant changes in risk management policy, including the introduction of state or national revenue insurance. We also pursue an empirical analysis of the interrelationships of crop insurance, disaster relief, and farm profitability. We find an inverse relationship between disaster assistance and insurance purchases. Our analysis also suggests that farmers that buy insurance and that receive disaster payments tend to have higher returns to farming.

description: In present cultural debate, the theme of biodiversity is considered one of the most important topic because it does not treat only the variety of living forms but it includes also the value of itself and its preservation. Analysing a lot of its peculiar aspects we take conscious about uniqueness of life and relationship with other fields of knowledge: science, epistemology, aesthetics, ethics, politics. This essay focus especially on the origin of life, the processes of morphogenesis in living forms and appearing of “aesthetics” qualities in biological world. The relation between biodiversity and aesthetic can help to understand the origin of human aesthetic sense.

description: We study the activated motion of adsorbed polymers which are driven over a structured substrate by a localized point force.Our theory applies to experiments with single polymers using, for example, tips of scanning force microscopes to drag the polymer.We consider both flexible and semiflexible polymers,and the lateral surface structure is represented by double-well or periodic potentials. The dynamics is governed by kink-like excitations for which we calculate shapes, energies, and critical point forces. Thermally activated motion proceeds by the nucleation of a kink-antikink pair at the point where the force is applied and subsequent diffusive separation of kink and antikink. In the stationary state of the driven polymer, the collective kink dynamics can be described by an one-dimensional symmetric simple exclusion process.

description: Moving from price-triggered to area revenue–triggered programs was perhaps the most common theme among 2007 farm bill proposals. Area revenue–triggered commodity programs may make farm-level revenue insurance products seem redundant, raising questions about why the federal government should continue both programs. Area revenue–triggered programs would remove much of the systemic risk faced by producers. As a result, private sector insurers may be able to insure the residual risk without federal involvement. This paper examines the effects of moving to area revenue–triggered commodity programs with a focus on public policy issues that would likely arise.

description: Government farm support programs such as Loan Deficiency Payments (LDP) and Counter-Cyclical Payments (CCP) have payoff structures that effectively make them costless price insurance instruments. A combination of these payments with yield insurance may provide a viable alternative to revenue insurance. This paper finds that, contrary to expectations, the revenue product analyzed is uniformly superior to yield insurance under both current (2002) and proposed (2008) Farm Bill structures of government payments. Given minor adjustments, however, yield insurance combined with government payments can provide more effective risk management than revenue insurance in production areas with low yield–price correlation.

description: We employ panoramic, multicolour (BRz') and narrow-band Halpha imaging of the cluster Cl0024.0+1652 (z=0.39) from Subaru covering a ~30 arcmin field, to determine cluster membership and star formation rates for a large sample of galaxies across a wide field in the cluster, ~10 Mpc. We detect over 500 galaxies in narrow-band emission, with broad-band colours consistent with them lying at z~0.39. Using this sample we determine the Halpha luminosity function within the cluster and find that its form is approximately independent of local density, and is consistent with that seen in the intermediate redshift field population. This suggests that any density-dependent physical mechanisms which alter the star formation rate must leave the Halpha luminosity function unchanged; this is possible if the time-scale for star formation to cease completely is short compared with a Hubble time. Such short time-scale transformations are also supported by the presence of a population with late-type morphologies but no detectable Halpha emission. The fraction of blue galaxies, and the fraction of galaxies detected in Halpha, decreases strongly with increasing galaxy density in a manner which is qualitatively similar to that seen at lower redshifts. This trend is significantly steeper than the trend with galaxy morphology observed from a panoramic Hubble Space Telescope image of this cluster; this suggests that the physical mechanisms responsible for transformations in morphology and star formation rates may be partially independent. Finally, we compare our data with similar data on clusters spanning a range of redshifts from 0.2

description: The crop insurance program has grown significantly since passage of the 2002 Farm Bill. Total premiums more than doubled from $2.9 billion in 2002 to $6.6 billion in 2007. This growth in the crop insurance program is due to a combination of greater participation by growers at higher levels of coverage, an increased number of crops with coverage available, and a general rise in commodity prices. Not unexpectedly, there has been a corresponding increase in the cost of program delivery. The total amount of expense subsidy and underwriting gains paid to crop insurance companies increased from around $1 billion in 20011 to over $2.5 billion in 2007.

Eventually, I discuss what Aesthetics may win by directing its attention to this author.

description: Il saggio descrive e analizza la teoria della rappresentazionalità presentata da Kendall Walton in Mimesi come far finta. Le rappresentazioni sono supporti atti a suscitare un far finta che si esplica come un immaginare proposizionale: ecco la tesi dell’autore. I caratteri di tale far finta, la dinamica della partecipazione, la distinzione tra figuralità e verbalità, e il problema delle entità fittizie, sono i punti cardine della proposta waltoniana. La questione dell’esperienza, e la sua possibile, originaria, tematizzazione estetica; il tema del rapporto tra emozioni fittizie e reali; e la maniera specifica in cui l’autore intende la mimesi della rappresentazione, sono, in particolare, gli aspetti che il saggio problematizza più estesamente. The essay is intended to describe while analyzing the theory of representationality as presented by Kendall Walton in Mimesis as Make-Believe. Representations are mediums leading to provoke a make-believe – its kind building up as propositional acts of imagination: such the thesis that the author asserts. Features of this make-believe, the dynamics of participation, the distinction between figurality and verbality, the problem of fictional entities, those are the nodal joints of the waltonian proposal. The question of experience – and its possible, originary, aesthetical thematization, the thematization of the relation between fictional and real emotions, and the specific sense in which the author draws the mimesis proper to representation: such the aspects which the present essay is mostly concerned with.

Messianica ratio. Affinities and Differences in Cohen’s and Benjamin's Messianic Rationalism
Creators: name: Desideri, Fabrizio
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2015

description: In my paper, I intend firmly to criticize Taubes' interpretation of Benjamin's Theology as a modern form of Gnosticism (Benjamin as a modern Marcionit). In a positive way, I sustain rather the thesis that Benjamin's Messianism is in close connection with his conception of reason (“the sharpened axe of reason”) and, in particularly, with the paradoxical unity of Mysticism and Enlightenment, which, according to the famous definition of Adorno, distinguishes his thought. As a radically anti-magical and anti-mythical conception of the historical time, Benjamin's Messianism has to be considered as an original synthesis between motifs of the mystical tradition of the Jewish Kabbalah and motifs belonging to the rationalist tradition of the Jewish philosophy. Moving from Cohen's standpoint of a continuity between Maimonides and Kant, I consider therefore the affinity between his messianic conception of history and that of Benjamin. Both, Benjamin and Cohen, share, together with the reference to the a priori of the idea of justice, the reference to the Kantian connection between rationality and hope. Hence originates the non-eschatological Messianism of both. Motives of difference between Cohen and Benjamin’s messianic idea are to be found, conversely, in their different way to consider the idea of "the infinite task" and of its infinite fulfillment in the context of the historical time. Unlike the fundamentally ethical interpretation that Cohen gives of this relationship, Benjamin understands it ontologically in a monadological sense. This explains the constitutive relationship that exists, in Benjamin's philosophy, between Origin, Fragment and Revelation. In the light of this connection, Benjamin's messianic understanding of the historical time exceeds the Scholemian alternative between a restorative and a utopian conception of Messianism. Consequently, the Krausian motto “Ursprung ist das Ziel” (“The Origin is the Goal”) displays its truth in the idea of the messianic fragment or spark.

description: Agricultural water use is becoming an issue in much of the South due to population growth. Results of projects evaluating the impacts of conservation strategies aimed at reallocating or extending the life of water supplies are being met with great skepticism by stakeholder groups. In order to gain acceptance of results, it is essential that stakeholder groups be involved from the beginning in the identification of potential water conservation strategies and be kept informed throughout the project. The objective of this paper is to review previous attempts at involving stakeholders and the methodology currently being employed in the Ogallala Aquifer Project.

description: Following the correct technology of winter wheat production and grain storage, you can get a high economic effect of the activity. Wheat is one of the first crops that were cultivated many years ago. And until now it deservedly occupies a leading place in the ranking of food products in about 50 countries around the world. Ukraine is also on this list, and in addition is a major producer and exporter of this cereal crop. In Ukraine, wheat is considered one of the main food crops. It is used to make a valuable and cult product for Ukrainians bread, so national economic importance of grain is difficult to underestimate. Quality bakery products determines the composition of grain. Among other grains, winter wheat contains a high percentage of protein, which reaches up to 15%, depending on the production technology and variety. In addition, the grain is rich in carbohydrates and other important trace elements..[ 1]. Among the crops grown in Ukraine, winter wheat is the leader in terms of sown area. And every year, despite the bad seasons and weather vagaries, the hectares of grain continue to remain at a stable level. So, for the 2020 harvest, 6400000 hectares of this winter crop were sown in Ukraine, which is 0.6% less than last year's figure. This relative stability is provided by the correct and modern technology of growing winter wheat, through which you can get a high result in agriculture. The determining factor of production, regardless of the region of Ukraine is the technology of growing winter wheat. It acts as a guide for the agronomist at all stages of the production process. In accordance with the selected technological scheme, all operations in the field, from preparation for sowing to harvesting, are carried out. Producers choose the growing technology themselves according to the natural and climatic characteristics and capabilities of the farm..[ 2].

The aim of the work was to verify the possibility maping of enderbites&charnokites of the abnormal magnetic field. The magnetic susceptibility Curie points of feromagnetic minerals and other properties of enderbites&charnokites were investigated. It is shown that the studies enderbites not create high positive anomalies of the magnetic field and are actually "dumb" in the anomalous magnetic field. On the prospect of suggested further study of those areas where high positive magnetic field anomalies coincide with places spread enderbite&charnokites. On the prospect of suggested further study of its rocks location where positive Bouguer anomalies and normal ore negative magnetic field anomalies

description: Pandres has shown that an enlargement of the covariance group to the group of conservative transformations leads to a richer geometry than that of general relativity. Using orthonormal tetrads as field variables, the fundamental geometric object is the curvature vector denoted by $C_μ$. From an appropriate scalar Lagrangian field equations for both free-field and the field with sources have been developed. We first review models which use a free-field solution to model the Solar System and why these results are unacceptable. We also show that the standard Schwarzschild metric is also unacceptable in our theory. Finally we show that there are solutions which involve sources which agree with general relativity PPN parameters and thus approximate the Schwarzschild solution. The main difference is that the Einstein tensor is not identically zero but includes small values for the density, radial pressure and tangential pressure. Higher precision experiments should be able to determine the validity of these models. These results add further confirmation that the theory developed by Pandres is the fundamental theory of physics.
ANALYSIS OF VARIANCE BETWEEN SOCIO ECONOMIC VARIABLES AND PURCHASE DECISION OF RURAL CUSTOMERS ON LIFE INSURANCE PRODUCTS OFFERED BY VARIOUS PRIVATE AND PUBLIC SECTOR INSURERS  IN TAMILNADU
Creators: name: Dr. P. Kamaraj
Publisher: name: Zenodo
Year: 2024

description: This study analyzes the relationship between socio-economic variables and the purchase decisions of rural customers regarding life insurance products from both private and public sector insurers. Using ANOVA techniques, the research reveals significant variances influenced by factors such as income, education, and occupation, highlighting the need for insurers to tailor their offerings to the specific needs of rural customers.

description: We present VLA images of the supernova remnant (SNR) 3C~391 at 74, 330, and 1465 MHz. This remnant has been known for some time to exhibit a turnover in its integrated radio continuum spectrum at frequencies < 100 MHz, indicative of free-free absorption from thermal ionized gas along the line of sight. For the first time, our data reveal the spatially resolved morphology of the low frequency free-free absorption with a resolution of ~70 arcsec. Contrary to the expectation that such absorption arises from unrelated low density HII regions (or their envelopes) along the line of sight, these data suggest that in this case the absorbing medium is directly linked to the SNR itself. 3C~391 has been shown in a number of recent papers to be interacting with a molecular cloud. Indeed, it exhibits a number of signposts of SNR/molecular cloud shocks including OH (1720 MHz) masers and broad molecular emission lines. Comparison of the regions of strongest 74 MHz absorption with existing X-ray, IR, and molecular data suggests that the free-free absorption originates from the SNR/molecular cloud shock boundaries due to ionized gas created from the passage of a J-type shock with a speed of ~100 km/s. This makes only the second SNR for which such (extrinsic) spatially resolved absorption has been measured, and the only one for which the absorption is thought to arise from a SNR/molecular cloud interface region.

description: The United States and Mexico recently resolved a decade-old water dispute that required Mexico to repay the accumulated water debt within one year. A Coasian analysis estimates the social welfare gains attainable to each country under an alternative debt repayment scheme that allows repayment over a longer time horizon and in a combination of dollars and water, instead of solely in water. Assuming average water supply conditions, under the agreed 1-year repayment contract, U.S. compensation value is 534% greater and Mexico’s compensation cost is 60% less relative to when compensation is paid exclusively in water.
Mechanics of non-planar membranes with force-dipole activity

Publisher: name: arXiv
Year: 2005
Subjects: subject: Soft Condensed Matter (cond-mat.soft)
subject: FOS: Physical sciences

description: A study is made of how active membrane proteins can modify the long wavelength mechanics of fluid membranes. The activity of the proteins is modelled as disturbing the protein surroundings through non-local force distributions of which a force-dipole distribution is the simplest example. An analytic expression describing how the activity modifies the force-balance equation for the membrane surface is obtained in the form of a moment expansion of the force distribution. This expression allows for further studies of the consequences of the activity for non-planar membranes. In particular the active contributions to mechanical properties such as tension and bending moments become apparent. It is also explained how the activity can induce a hydrodynamic attraction between the active proteins in the membrane.

The Feynman propagator for quantum gravity: spin foams, proper time, orientation, causality and timeless-ordering

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We discuss the notion of causality in Quantum Gravity in the context of sum-over-histories approaches, in the absence therefore of any background time parameter. In the spin foam formulation of Quantum Gravity, we identify the appropriate causal structure in the orientation of the spin foam 2-complex and the data that characterize it; we construct a generalised version of spin foam models introducing an extra variable with the interpretation of proper time and show that different ranges of integration for this proper time give two separate classes of spin foam models: one corresponds to the spin foam models currently studied, that are independent of the underlying orientation/causal structure and are therefore interpreted as a-causal transition amplitudes; the second corresponds to a general definition of causal or orientation dependent spin foam models, interpreted as causal transition amplitudes or as the Quantum Gravity analogue of the Feynman propagator of field theory, implying a notion of ''timeless ordering''.

description: By allowing torsion into the gravitational dynamics one can promote the cosmological constant, $Λ$, to a dynamical variable in a class of quasi-topological theories. In this paper we perform a mini-superspace quantization of these theories in the connection representation. If $Λ$ is kept fixed, the solution is a delta-normalizable version of the Chern-Simons (CS) state, which is the dual of the Hartle and Hawking and Vilenkin wave-functions. We find that the CS state solves the Wheeler-DeWitt equation also if $Λ$ is rendered dynamical by an Euler quasi-topological invariant, {\it in the parity-even branch of the theory}. In the absence of an infra-red (IR) cut-off, the CS state suggests the marginal probability $P(Λ)=δ(Λ)$. Should there be an IR cutoff (for whatever reason) the probability is sharply peaked at the cut off. In the parity-odd branch, however, we can still find the CS state as a particular (but not most general) solution, but further work is needed to sharpen the predictions. For the theory based on the Pontryagin invariant (which only has a parity-odd branch) the CS wave function no longer is a solution to the constraints. We find the most general solution in this case, which again leaves room for a range of predictions for $Λ$.

Multilevel debugging of parallel message passing programs
Creators: name: Pedersen, Jan Bækgaard
Publisher: name: University of British Columbia
Year: 2009

description: "Errare humanum est" - To err is human (Hieronymus, Epistle 57, 12); this fact has been known throughout time, and inevitably this means that humans writing computer programs are bound to introduce errors. With computers operating in Frankenstein's Igor mode, 'Your wish is my command', executing instructions without questioning their validity, errors introduced by humans are carried out. When adding parallel programming with message passing an error in one process can spread like a virus through message passing to other processes. Much research has been done on debugging sequential programs, and most of these theories and results apply directly to parallel programs, but the set of potential errors dramatically increases in size when introducing parallelism and message passing. Not only can one process fail, but sets of processes can deadlock, computational errors can be propagated from process to process, thus infecting otherwise correct programs. Correct programs can stop working because of the underlying implementation of the message passing system. We propose a framework for debugging parallel message passing programs: a multilevel approach that divides errors into separate groups at various levels from the well known sequential errors, such as stray pointers and array out of bound, to deadlock caused by incorrect message passing code, protocol errors and buffer allocation problems. We show the validity of this approach by developing new debugging techniques and analyses, and by implementing these in Millipede, a prototype multilevel debugger written for C programs that use the PVM message passing system.
A Field Theoretical Model in Noncommutative Minkowski Superspace

description: In this talk we present a field theoretical model constructed in Minkowski N=1 superspace with a deformed supercoordinate algebra. Our study is motivated in part by recent results from super-string theory, which show that in a particular scenario in Euclidean superspace the spinor coordinates θdo not anticommute. Field theoretical consequences of this deformation were studied in a number of articles. We present a way to extend the discussion to Minkowski space, by assuming non-vanishing anticommutators for both θ, and \barθ. We give a consistent supercoordinate algebra, and a star product that is real and preserves the (anti)chirality of a product of (anti)chiral superfields. We also give the Wess-Zumino Lagrangian that gains Lorentz-invariant corrections due to non(anti)commutativity within our model. The Lagrangian in Minkowski superspace is also always manifestly Hermitian.

I highlight, somewhat idiosyncratically, ten such differences under three broad headings: Facts and Empirics, Concepts and Theory, and Policies and Interventions.
