An event-related potential investigation of inhibition of return
Creators: name: Prime, David J.

description: In visual spatial-cueing experiments with uninformative peripheral cues, reaction time to cued-location targets is facilitated (relative to that for targets at uncued-locations) at short cue-target intervals and inhibited at longer intervals. Posner, Rafal, Choate and Vaughan (1985) labeled this inhibitory effect Inhibition of Return (IOR) and proposed that it serves to bias the visual system to orient towards new locations. This proposal remains a popular topic of debate and no consensus has yet been reached regarding the mechanisms responsible for producing IOR. The present project utilized event-related potential (ERP) measures of brain activity to investigate the processing changes underlying IOR. I examined the effect of uninformative visual cues both on the amplitude of early visual ERP peaks and on the motorrelated lateralized readiness potential (LRP). The LRP is a measure of motor cortex activity that is related to the preparation of responses. The onset of the LRP relative to the target and response provide relative measures of the duration of premotor and motor processes, respectively. Chapters 2 and 3 present the results of four experiments, in which observers were required to make manual responses to visual targets. In each experiment the target was preceded by an uninformative peripheral cue followed by a central re-orienting event. In separate experiments, subjects were required to make identity-based discrimination responses, localization responses, detection responses, or identity-based go-nogo responses. In each of these experiments IOR was associated with a slowing of premotor processes. The duration of motor processes were not affected, however, indicating that, when measured with manual keypresses, IOR does not arise from inhibition of motor processes. Consistent with a perceptual locus of IOR, the amplitudes of the occipital ERP peaks were reduced for cuedlocation targets relative to uncued-location targets. In a fifth experiment (Chapter 5) the reorienting event was omitted and subjects were required to discriminate the target identity. Compared to when a re-orienting event was present, the magnitude of both IOR and the ERP amplitude effects were reduced. This co-variation of behavioural and ERP effects suggests that that changes in the perceptual processes are, at least in part, responsible for generating IOR.

description: We present a novel quantum algorithm for solving the unstructured search problem with one marked element. Our algorithm allows generating quantum circuits that use asymptotically fewer additional quantum gates than the famous Grover's algorithm and may be successfully executed on NISQ devices. We prove that our algorithm is optimal in the total number of elementary gates up to a multiplicative constant. As many NP-hard problems are not in fact unstructured, we also describe the \emph{partial uncompute} technique which exploits the oracle structure and allows a significant reduction in the number of elementary gates required to find the solution. Combining these results allows us to use asymptotically smaller number of elementary gates than the Grover's algorithm in various applications, keeping the number of queries to the oracle essentially the same. We show how the results can be applied to solve hard combinatorial problems, for example Unique k-SAT. Additionally, we show how to asymptotically reduce the number of elementary gates required to solve the unstructured search problem with multiple marked elements.

description: El artículo analiza el impacto de la Inteligencia Artificial (IA) en la valoración de activos financieros, destacando cómo las tecnologías emergentes están revolucionando los métodos tradicionales de valoración. En un entorno financiero caracterizado por alta volatilidad y complejidad, la IA ha demostrado ser una herramienta clave para mejorar la precisión y eficiencia en la evaluación de activos, optimizando los procesos de toma de decisiones y reduciendo el riesgo asociado a las inversiones.La IA permite procesar grandes volúmenes de datos no estructurados, como informes financieros, noticias y redes sociales, lo que facilita la identificación de patrones complejos y la predicción de comportamientos de mercado. Los modelos tradicionales de valoración, que suelen basarse en métodos estadísticos y matemáticos, son limitados en su capacidad para incorporar estos datos no convencionales. En este contexto, los algoritmos de aprendizaje automático (Machine Learning) permiten realizar ajustes continuos y mejorar las predicciones a medida que se incorpora nueva información, lo que hace que los modelos de valoración sean más dinámicos y adaptativos.El artículo también explora cómo la implementación de la IA en la valoración de activos puede reducir los costos operativos y aumentar la transparencia en la toma de decisiones. A través de casos de estudio y ejemplos prácticos, se demuestra cómo las instituciones financieras están adoptando la IA para optimizar la gestión de riesgos y mejorar la precisión en la evaluación de activos.

description: We have carried out a thorough optical study of the closest star formation jet. The inner arcminute surrounding the class 0/I binary protostar L1551 IRS5 and its associated jet (HH154) have been observed using the Hubble Space Telescope with the WFPC2 camera, the ESO New Technology Telescope with the EMMI spectrograph and the Nordic Optical Telescope with the ALFOSC spectrograph. This data set is compared to earlier ground based imaging with the aim to study the evolution of this particular jet, and its possible interaction with the molecular material in the bipolar molecular outflow associated with this source. The velocity field of the jet is mapped out. The highest velocities are found in the vicinity of the recently discovered X-ray source emanating from a shock in this jet. The energy radiated by the X-ray source is compatible with these velocities. The \halpha and \hbeta emission from the jet is used to determine the extinction, which is found to increase inwards in the jet towards the protostar. The extinction towards the X-ray source is consistent with the one determined from the X-ray spectrum.

description: The product life cycle of the new value added marketing strategy that a quality heifer program created in adding, a new product (heifers with additional value characteristics) is explored. The new product that will be examined is related to the Show-Me Select Heifer Replacement program. The Tier II program has essentially created a new product (higher quality bred heifers) by using minimum EPD accuracies for calving ease along with expected calf and carcass performance measurements. The hedonic study shows that that the Tier II heifers receive a premium compared to traditional Show-Me-Select heifers. The first year Tier II heifers came on the market in 2008 they received a discount of $24 as compared to regular Show-Me-Select Heifers. However, the following year the Tier II heifers received a premium of $138 while dropping to a premium of $46 in 2010. It appears since the Tier II program is in an infancy stage where premium values are still being determined.

description: We use a panel survey at the household level primarily conducted in 18 natural villages over three waves in Guizhou province, China, to study how improved road access shapes farmers’ cropping and input use. Our results show that access to roads significantly improves the level of specialization in household agricultural production as measured by the Herfindahl-Hirschman Index. In villages with better road access, farmers plant fewer crops and invest more intermediate input. Through specialization and increased use of intermediate input, road connections improve farmers’ agricultural income and total income per capita. In addition, the cash income of agricultural product also increases, providing evidence of more trading of produced goods due to better connectivity. However, better access to rural roads does not seem to bring about significant changes in non-agricultural income.

The Minimum Mass for Opacity-Limited Fragmentation in Turbulent Cloud Cores

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

description: We present a new analysis of the minimum mass for star formation, based on opacity-limited fragmentation. Our analysis differs from the standard one, which considers hierarchical fragmentation of a 3-D medium, and yields $M_{_{\rm MIN}} \sim 0.007 {\rm to} 0.010 M_\odot$ for Population I star formation. Instead we analyse the more realistic situation in which there is one-shot fragmentation of a shock-compressed layer, of the sort which arises in turbulent star-forming clouds. In this situation, $M_{_{\rm MIN}}$ can be smaller than $0.003 M_\odot$. Our analysis is more stringent than the standard one in that (a) it requires fragments to have condensation timescales shorter than all competing mass scales, and (b) it takes into acount that a fragment grows by accretion whilst it is condensing out, and has to radiate away the energy dissipated in the associated accretion shock. It also accords with the recent detection, in young star clusters, of free-floating star-like objects having masses as low as $0.003 {\rm M}_\odot$.

description: As inkjet technology develops to produce smaller droplets, substrate features such as accidental scratches or manufacturing defects can potentially affect the outcome of printing, particularly for printed electronics where continuous tracks are required. Here, the deposition of micro-droplets onto a scratch of commensurate size is studied. The scratch is considered as a groove of rectangular cross-section, with rectangular side ridges representing material displaced from the substrate, and seven equilibrium morphologies are identified as a result of inertial spreading, contact-line pinning, imbibition into the scratch and capillary flow. A regime map is constructed in terms of scratch depth and width, and theoretical estimates of the regime boundaries are developed by adapting droplet spreading laws for flat surfaces to account for liquid entering the scratches. Good agreement is seen with numerical results obtained using a GPU-accelerated three-dimensional multiphase lattice Boltzmann model validated against published experiments, and the influences of Reynolds number, Weber number and advancing and receding contact angles are explored. Negative and positive implications of the results for printing applications are discussed and illustrated via multiple-droplet simulations of printing across and along scratches.

description: The FDA Food Safety Modernization Act of 2010 is new legislation that mandates, among other things, new food safety standards. The act includes a clause that exempts small firms from new regulatory requirements. This paper investigates the effects of a small firm exemption from more stringent food safety standards. The model compares food safety, total output and the number of market participants for different food safety regulation with and without an exemption for small firms. The numerical examples show that a more stringent food safety regulation increases food safety, increases the price of food, decreases the total output and decreases the number of firms. A new food safety standard with an exemption for small firms increases the average food safety but not as much as with a new standard alone. An exemption for small firms causes the total number of firms to increase.
The effective action of Type IIA Calabi-Yau orientifolds

description: The N=1 effective action for generic type IIA Calabi-Yau orientifolds in the presence of background fluxes is computed from a Kaluza-Klein reduction. The Kahler potential, the gauge kinetic functions and the flux-induced superpotential are determined in terms of geometrical data of the Calabi-Yau orientifold and the background fluxes. The moduli space is found to be a Kahler subspace of the N=2 moduli space and shown to coincide with the moduli space arising in compactification of M-theory on a specific class of G_2 manifolds. The superpotential depends on all geometrical moduli and vanishes at leading order when background fluxes are turned off. The N=1 chiral coordinates linearize the appropriate instanton actions such that instanton effects can lead to holomorphic corrections of the superpotential. Mirror symmetry between type IIA and type IIB orientifolds is shown to hold at the level of the effective action in the large volume - large complex structure limit.

description: The Kaczmarz method for solving a linear system $Ax = b$ interprets such a system as a collection of equations $\left\langle a_i, x\right\rangle = b_i$, where $a_i$ is the $i-$th row of $A$, then picks such an equation and corrects $x_{k+1} = x_k + λa_i$ where $λ$ is chosen so that the $i-$th equation is satisfied. Convergence rates are difficult to establish. Assuming the rows to be normalized, $\|a_i\|_{\ell^2}=1$, Strohmer \& Vershynin established that if the order of equations is chosen at random, $\mathbb{E}~ \|x_k - x\|_{\ell^2}$ converges exponentially. We prove that if the $i-$th row is selected with likelihood proportional to $\left|\left\langle a_i, x_k \right\rangle - b_i\right|^{p}$, where $0

Spectroscopic monitoring of rapidly-rotating early-type stars in the Pleiades cluster
Creators: name: Torres, Guillermo
Publisher: name: arXiv
Year: 2020
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Radial-velocities for the early-type stars in the Pleiades cluster have always been challenging to measure because of the significant rotational broadening of the spectral lines. The large scatter in published velocities has led to claims that many are spectroscopic binaries, and in several cases preliminary orbital solutions have been proposed. To investigate these claims, we obtained and report here velocity measurements for 33 rapidly-rotating B, A, and early F stars in the Pleiades region, improving significantly on the precision of the historical velocities for most objects. With one or two exceptions, we do not confirm any of the previous claims of variability, and we also rule out all four of the previously published orbital solutions, for HD 22637, HD 23302, HD 23338, and HD 23410. We do find HD 22637 to be a binary, but with a different period (71.8 days). HD 23338 is likely a binary as well, with a preliminary 8.7 yr period also different from the one published. Additionally, we report a 3635 day orbit for HD 24899, another new spectroscopic binary in the cluster. From the 32 bona fide members in our sample we determine a mean radial velocity for the Pleiades of 5.79 +/- 0.24 km/s, or 5.52 +/- 0.31 km/s when objects with known visual companions are excluded. Adding these astrometric binaries to the new spectroscopic ones, we find a lower limit to the binary fraction among the B and A stars of 37%. In addition to the velocities, we measure v sin i for all stars, ranging between 69 and 317 km/s.

description: We study the focusing of atoms by multiple layers of standing light waves in the context of atom lithography. In particular, atomic localization by a double-layer light mask is examined using the optimal squeezing approach. Operation of the focusing setup is analyzed both in the paraxial approximation and in the regime of nonlinear spatial squeezing for the thin-thin as well as thin-thick atom lens combinations. It is shown that the optimized double light mask may considerably reduce the imaging problems, improve the quality of focusing and enhance the contrast ratio of the deposited structures.

description: We investigate the formation of subaqueous transverse bedforms in turbulent open channel flow by means of direct numerical simulations with fully-resolved particles. The main goal of the present analysis is to address the question whether the initial pattern wavelength scales with the particle diameter or with the mean fluid height. A previous study (Kidanemariam and Uhlmann, J. Fluid Mech., vol. 818, 2017, pp. 716-743) has observed a lower bound for the most unstable pattern wavelength in the range 75-100 times the particle diameter, which was equivalent to 3-4 times the mean fluid height. In the current paper, we vary the streamwise box length in terms of the particle diameter and of the mean fluid height independently in order to distinguish between the two possible scaling relations. For the chosen parameter range, the obtained results clearly exhibit a scaling of the initial pattern wavelength with the particle diameter, with a lower bound around a streamwise extent of approximately 80 particle diameters. In longer domains, on the other hand, patterns are observed at initial wavelengths in the range 150-180 times the particle diameter, which is in good agreement with experimental measurements. Variations of the mean fluid height, on the other hand, seem to have no significant influence on the most unstable initial pattern wavelength. Furthermore, for the cases with the largest relative submergence, we observe spanwise and streamwise sediment waves of similar amplitude to evolve and superimpose, leading to three-dimensional sediment patterns.

Foraging ecology of coyotes in the Alaska range
Creators: name: Prugh, Laura
Publisher: name: University of British Columbia
Year: 2009

description: Predation strongly affects the dynamics of northern vertebrate communities through direct and indirect pathways. Coyotes are one of the main predators of snowshoe hares, and hare populations are characterized by cyclic fluctuations with peaks every 8-11 years. Northern coyotes rely on hares as their primary food source, but they are also major predators of Dall sheep lambs. I examined the response of coyotes to the snowshoe hare population decline in the Alaska Range from 1999-2002 and evaluated the impact of coyote predation on other species in the vertebrate prey community. I first addressed these issues at the population level and then examined the foraging behavior of individual coyotes and social groups. Snowshoe hare abundance declined 10-fold and had a strong effect on coyote diet composition. The absolute biomass of hares was a good predictor of the amount of carrion, voles, porcupine, and hare in the diet, and coyotes were relatively insensitive to changes in the abundance of alternative prey. Coyote selection for hares and porcupines increased as hare numbers declined, and per-capita consumption of porcupines increased 25-fold. Conversely, voles irrupted and represented 61% of available prey biomass by the end of the hare decline, but coyote selection for voles did not increase. Coyote per-capita consumption of Dall sheep was not affected by sheep or hare abundance. Because coyote predation on alternative prey was not dependent on alternative prey density, it was not a stabilizing influence on the prey community. Coyote numbers declined nearly 2-fold during the snowshoe hare decline, with peak coyote numbers occurring 1½ years after the hare peak. Mortality and emigration increased immediately following the peak in coyote numbers, followed by reproductive failure during the low phase of the hare cycle. Coyote-inflicted mortality on Dall sheep lambs fell 3-fold when coyote reproduction failed. Lamb survival was negatively related to hare abundance, showing a limit cycle with a 2-year time delay. Thus, snowshoe hare abundance indirectly affects Dall sheep populations via a numerical response by coyotes. Diet composition varied among individual coyotes and social groups. The pattern of snowshoe hare consumption by social groups largely mirrored the pattern of hare abundance in space and time, indicating that patchiness in prey abundance may have been the main cause of diet variation among coyote groups. Adult coyotes with higher proportions of hare and vole in their diets and lower proportions of porcupine and carrion had increased chances of surviving the hare decline and remaining in the study area.

description: Cosmological N-body simulations have been a major tool of theorists for decades, yet many of the numerical issues that these simulations face are still unexplored. This paper measures numerical biases in these large, dark matter-only simulations that affect the properties of their dark matter haloes. We compare many simulation suites in order to provide several tools for simulators and analysts which help mitigate these biases. We summarise our comparisons with practical `convergence limits' that can be applied to a wide range of halo properties, including halo properties which are traditionally overlooked by the testing literature. We also find that the halo properties predicted by different simulations can diverge from one another at unexpectedly high resolutions. We demonstrate that many halo properties depend strongly on force softening scale and that this dependence leads to much of the measured divergence between simulations. We offer an empirical model to estimate the impact of such effects on the rotation curves of a halo population. This model can serve as a template for future empirical models of the biases in other halo properties.

description: Este trabalho objetiva mensurar a volatilidade dos preços futuros do açúcar negociados na BM&F, bem como verificar quais entre os modelos univariados propostos apresenta melhor desempenho preditivo para o preço da commodity em questão. Para tanto se utilizam modelos de análise de volatilidade do tipo ARCH e modelos univariados de previsão aplicados a séries temporais, entre os quais os modelos ARIMA e SARIMA. Os resultados empíricos sugerem não haver presença de assimetria entre choques positivos e negativos e indicam a persistência na volatilidade dos preços do açúcar, implicando que os choques de volatilidade se dissiparão lentamente ao longo do tempo, podendo gerar perdas econômicas. Quanto aos modelos de previsão, o modelo ARIMA apresentou os menores valores para os critérios Akaike e Schwarz e para a soma dos quadrados dos resíduos. Porém o modelo SARIMA apresentou melhor ajuste teórico à série de preços do açúcar, bem como para o erro quadrado médio de previsão (EQM) ex-post.-------------------------------------The aim of this work is to measure the volatility of sugar prices negotiated in BM&F, as well as to verify which among the univariate models proposed presents a better predictive performance regarding the price of the referred commodity. To do this it is used ARCH models of volatility analysis and univariate prevision models applied to temporal series, among them the ARIMA and SARIMA models. The empirical results suggest there is no asymmetry between positive and negative impacts and indicate the persistence of volatility of sugar prices, resulting that the volatility impacts will dissipate slowly along the time, with the possibility of generating economical losses. As regards the Prevision Models, the ARIMA model presented the lowest values to the criteria Akaike and Schwarz and to the sum-of-squares of residues. However, the SARIMA Model presented better theoretical adjustment to the series of sugar prices, as well as to the Prediction Mean Square Error (EQM) ex-post.

description: Globally, nearly 9 million children die before year of five yearly due to pneumonia, diarrhoea malaria and other diseases according to the latest estimates in 2008 (WHO/UNICEF, 2010a, p.11). This represents a tremendous improvement in contrast to child mortality in 1970 (17 million), however much remains to be done, since children and infants are a vulnerable group whose voice is hardly heard. It is estimated that globally over 4,100 children under-five die each day due to diarrhoea alone, with 46% of all child diarrhoea death occurring in Sub-Saharan Africa where 10 out of 15 countries globally with the highest rates are located (UNICEF/WHO, 2009, p.7). Diarrhoea therefore becomes the biggest killer for death of children under-five in Sub-Saharan African countries (Velleman and Slaymaker, 2011, p.5)....

description: We observed the 2003 X-ray outburst of H1743-322 in a series of 130 pointed observation with RXTE. We searched individual observations for high-frequency QPOs (HFQPOs) and found only weak or marginal detections near 240 and 160 Hz. We next grouped the observations in several different ways and computed the average power-density spectra (PDS) in a search for further evidence of HFQPOs. This effort yielded two significant results for those observations defined by the presence of low-frequency QPOs (0.1-20 Hz) and an absence of ``band-limited'' power continua: (1) The 9 time intervals with the highest 7-35 keV count rates yielded an average PDS with a QPO at $166 \pm 5$ Hz. ($4.1 σ$; 3--35 keV); and (2) a second group with lower 7-35 keV count rates (26 intervals) produced an average PDS with a QPO at $242 \pm 3$ Hz ($6.0 σ$; 7--35 keV). The ratio of these two frequencies is $1.46 \pm 0.05$. This finding is consistent with results obtained for three other black hole systems that exhibit commensurate HFQPOs in a 3:2 ratio. Furthermore, the occurrence of H1743-322's slower HFQPO at times of higher X-ray luminosity closely resembles the behavior of XTE J1550-564 and GRO J1655-40. We discuss our results in terms of a resonance model that invokes frequencies set by general relativity for orbital motions near a black-hole event horizon.

Giving advertisers the benefit of the doubt : trust, cooperative communication, and consumer acceptance of implication in advertising
Creators: name: Ritchie, Robin John Brent
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation seeks to expand our understanding of why consumers "go with the gist" of ads that imply more than they literally claim. Such persuasion is especially surprising in light of several facts: (1) the goal o f advertising is to induce purchase, giving advertisers an incentive to exaggerate through implication in order to maximize the appeal of their products; (2) polls have consistently found a high level of public cynicism toward marketers, and; (3) consumers are generally believed to be active and skeptical users of information. Working from linguistics research on conversational implicature, I develop a conceptual framework to explain the process by which implied advertising claims persuade. A central element of this framework is the cooperative principle o f conversation - the presumption that speakers will normally try to design messages that are truthful, unambiguous, and mindful of both the context of the conversation and the pre-existing knowledge of the recipient. Conversational implicature theory holds that widespread adherence to the cooperative principle in everyday communication (a) makes it possible for listeners to reconstruct the intended meaning of a message, and (b) makes it reasonable for them to favor this meaning over its literal interpretation. However, such cooperativeness on the part of the recipient is believed to occur only when that individual has at least a nominal level of trust in the communicator, implying that phenomena which undermine trust will have particularly negative consequences for advertisements in which claims are implied rather than explicitly stated. Hypotheses flowing from the proposed framework are tested using two experiments, which manipulate individuals' general level of suspicion toward advertising (high vs. low) and the nature of the advertising claim (implied vs. stated), and investigate the effects of these manipulations on attitudes and information processing. The first experiment establishes the effects for two types of implied advertising claims (qualified claim and missing information), while the second clarifies some questions raised by the initial study, and explores the moderating effects of having a reputable brand. Results from these two studies provide reasonable support for the notion that consumers accept implied advertising claims because they are acting as cooperative message recipients whose goal is to infer the intended meaning of the communicator. Under normal circumstances, individuals expressed a moderate level of trust toward the advertiser, and there was no difference in the effectiveness of stated claims and claims made by implication. However, when feelings of general suspicion toward marketers were induced, trust in the specific advertiser was undermined and implied claims resulted in less favorable attribute beliefs and product attitudes than did claims that were stated outright.

description: We present the discovery of the radio afterglow and near-infrared (NIR) counterpart of the Swift short GRB 200522A, located at a small projected offset of $\approx 1$ kpc from the center of a young, star-forming host galaxy at $z=0.5536$. The radio and X-ray luminosities of the afterglow are consistent with those of on-axis cosmological short GRBs. The NIR counterpart, revealed by our HST observations at a rest-frame time of $\approx2.3$ days, has a luminosity of $\approx (1.3-1.7) \times 10^{42}$ erg s$^{-1}$. This is substantially lower than on-axis short GRB afterglow detections, but is a factor of $\approx 8$-$17$ more luminous than the kilonova of GW170817, and significantly more luminous than any kilonova candidate for which comparable observations exist. The combination of the counterpart's color ($i-y = -0.08\pm 0.21$; rest-frame) and luminosity cannot be explained by standard radioactive heating alone. We present two scenarios to interpret the broad-band behavior of GRB 200522A: a synchrotron forward shock with a luminous kilonova (potentially boosted by magnetar energy deposition), or forward and reverse shocks from a $\approx14^{\circ}$, relativistic ($Γ_0 \gtrsim 80$) jet. Models which include a combination of enhanced radioactive heating rates, low-lanthanide mass fractions, or additional sources of heating from late-time central engine activity may provide viable alternate explanations. If a stable magnetar was indeed produced in GRB 200522A, we predict that late-time radio emission will be detectable starting $\approx 0.3$-$6$ years after the burst for a deposited energy of $\approx 10^{53}$ erg. Counterparts of similar luminosity to GRB 200522A associated with gravitational wave events will be detectable with current optical searches to $\approx\!250$ Mpc.

description: Este trabalho tem o objetivo de determinar quais foram as fontes de crescimento da produção agrícola no Estado de São Paulo entre 1990 e 2005. Para essa análise utilizou-se o modelo econométrico denominado “shift-share”, também conhecido como estrutural-diferencial. A análise foi dividida em subperíodos, tendo como objetivo abordar o comportamento da produção agrícola em diversos momentos da economia brasileira. Os fatores que explicam a evolução da produção nos subperíodos determinados foram os efeitos área, rendimento e localização geográfica. As alterações na área cultivada por sua vez foram subdivididas em efeito escala e substituição. A mandioca foi a cultura que apresentou maior crescimento da produção agrícola entre 1990 e 1995, o que se deu em razão do acréscimo na área cultivada. No segundo sub-período analisado (1995 a 2000), os ganhos de produção ocorreram com maior intensidade na cultura da banana (27,20% a.a) também em decorrência de acréscimos na área cultivada. E no último subperíodo (2001 a 2005), a maior crescimento da produção ocorreu no trigo (61,31% a.a). --------------------------------------------This study aims to determine what were the sources of growth of agricultural production in the state of Sao Paulo between 1990 and 2005. For this analysis used is the econometric model called "shift-share", also known as structural-differential. The analysis was divided into sub periods, with the aim address the behavior of agricultural production in various stages of the Brazilian economy. The factors that explain the evolution of production in certain sub periods were the effects area, income and geographic location. Changes in the area cultivated in turn were subdivided into effect and scale replacement. The cassava was the culture that had higher growth in agricultural production between 1990 and 1995, which occurred because of the increase in the area cultivated. In the second sub-analysis period (1995 to 2000), the gains in production occurred with greater intensity in the culture of banana (27.20% pa) also due to increases in the area cultivated. And in the last sub period (2001 to 2005), the largest growth in production occurred in the wheat (61.31% pa).

description: We report on the first pointed X-ray observations with XMM-Newton and RXTE satellites of the X-ray source RXJ0757.0+6306=HT Cam. We detect a strong 515s X-ray modulation confirming the optical photometric period found in 1998, which definitively assigns this source to the intermediate polar class of magnetic cataclysmic variables. The lack of orbital sidebands in the X-rays indicates that the X-ray period is the spin period of the accreting white dwarf. Simultaneous ultraviolet and optical B-band photometry acquired with the XMM-Newton Optical Monitor and coordinated optical UBVRI photometric data acquired at the Nordic Optical Telescope (La Palma) show that the optical pulse is in phase with the X-rays and hence originates in the magnetically confined accretion flow. The lack of ultraviolet spin modulation suggests that accretion-induced heating on the white dwarf surface is not important in this source. Spectral analyses of XMM-Newton EPIC and RGS spectra show that HT Cam has a multi-temperature spectrum and, contrary to most intermediate polars, it does not suffer from strong absorption. With its 86min orbital period, HT Cam is then the third confirmed system of this class below the 2-3hr period gap accreting at a low rate.

Scaling tests with dynamical overlap and rooted staggered fermions

description: We present a scaling analysis in the 1-flavor Schwinger model with the full overlap and the rooted staggered determinant. In the latter case the chiral and continuum limit of the scalar condensate do not commute, while for overlap fermions they do. For the topological susceptibility a universal continuum limit is suggested, as is for the partition function and the Leutwyler-Smilga sum rule. In the heavy-quark force no difference is visible even at finite coupling. Finally, a direct comparison between the complete overlap and the rooted staggered determinant yields evidence that their ratio is constant up to $O(a^2)$ effects.
