description: This paper presents the results of a set of radiative hydrodynamic (RHD) simulations of convection in the near-surface regions of a rapidly rotating star. The simulations use microphysics consistent with stellar models, and include the effects of realistic convection and radiative transfer. We find that the overall effect of rotation is to reduce the strength of turbulence. The combination of rotation and radiative cooling creates a zonal velocity profile in which the motion of fluid parcels near the surface is independent of rotation. Their motion is controlled by the strong up and down flows generated by radiative cooling. The fluid parcels in the deeper layers, on the other hand, are controlled by rotation.

Design of a Quantum Source of High-Frequency Gravitational Waves (HFGW) and Test Methodology

subject: FOS: Physical sciences

description: The generation of High-Frequency Gravitational Waves (HFGW) has been identified as the required breakthrough that will lead to new forms of space propulsion. Many techniques have been devised to generate HFGW, but most of them exhibit marginal efficiency, therefore the power emitted in form of gravitational waves (GW) is orders of magnitude lower than the input power. The gravitational wave counterpart of the LASER, termed Gravitational-wave LASER or "GASER" is the quantum approach to the efficient generation of gravitational waves. Electrons, protons, muons, etc, all have charge and mass, if accelerated they usually lose energy through the very fast electric and magnetic channels, this causes a negligible emission through the gravitational channel. Quantum systems can be engineered to forbid electric and magnetic transitions, therefore the gravitational spin-2 transitions can take place. A class of active materials, suitable for making a GASER based on electronic transitions in the solid state, is identified along with their relevant physical properties. Means for creating coherence and population inversion and means to increase the emission probability are described. The expected performances of the device are derived from quantum gravitational theories. Additional properties of the active materials are considered to enforce the theoretical foundation of the device. A proof-of-concept device, operating at about 1 THz, is described. Experiments are proposed as a natural starting point of the research.

description: The generation of electric energy by the sugarcane sector stands much below its potential. Using ﬁve case studies with São Paulo plants, this article aims to identify the obstacles to the expansion of the electric energy commercialization by the sugarcane sector. High costs associated to the commercialization of electric energy - in commercialization of excesses, and in the acquisition for proper consumption – are the most reasonable explanation for the self-sufﬁciency in the production of electric power by the sugarcane sector, an allied energy to the small generation of excesses of energy for commercialization. Out of the ﬁve plants studied, three plants that commercialize energy excesses make it as part of a strategy of anticipation of the future need of self-sufﬁciency. Having associated costs for sale of excesses of electric energy, they do not have incentives to the use of technologies of higher energy efﬁciency. The public policy directed to the expansion of energy excesses must turn toward the reduction of the costs associated to the commercialization thereof. Particularly interesting it would be to increase the volume of free consumers and to support the commercialization between these and the co-generators of energy.
Optimal observables and phase-space ambiguities

description: Optimal observables are known to lead to minimal statistical errors on parameters for a given normalised event distribution of a physics reaction. Thereby all statistical correlations are taken into account. Therefore, on the one hand they are a useful tool to extract values on a set of parameters from measured data. On the other hand one can calculate the minimal constraints on these parameters achievable by any data-analysis method for the specific reaction. In case the final states can be reconstructed without ambiguities optimal observables have a particularly simple form. We give explicit formulae for the optimal observables for generic reactions in case of ambiguities in the reconstruction of the final state and for general parameterisation of the final-state phase space.

description: Combining the augmented space representation for phonons with a generalized version of Yonezawa-Matsubara diagrammatic technique, we have set up a formalism to seperate the coherent and incoherent part of the total intensity of thermal neutron scattering from disordered alloys. This is done exacly without taking any recourse to mean-field like approximation (as done previously). The formalism includes disorder in masses, force constants and scattering lengths. Implementation of the formalism to realistic situations is performed by an augmented space Block recursion which calculates entire Green matrix and self energy matrix which in turn is needed to evaluate the coherent and incoherent intensities. we apply the formalism to NiPd and NiPt alloys. Numerical results on coherent and incoherent scattering cross sections are presented along the highest symmetry directions. Finally the incoherent intensities are compared with the CPA and also with experiments.

description: El sector ovino aragonés tiene un carácter dual. Al lado de explotaciones tradicionales con un carácter netamente familiar, escasa incorporación de personal asalariado e instalaciones ya amortizadas, en los últimos años se ha ido configurando un nuevo sector caracterizado por explotaciones de mayor dimensión, instalaciones modernas, cierta tecnificación e incorporación de personal asalariado. La crisis actual que vive el sector junto con la reciente reforma de la OCM de ovino ha generado cierta incertidumbre en los ganaderos sobre su futuro. El objetivo de este trabajo se centra, precisamente, en analizar cuáles son sus expectativas de futuro ante los nuevos acontecimientos. A partir de los resultados de una encuesta realizada a una muestra representativa de los sistemas de producción existentes en Aragón, se caracteriza sociodemográficamente al responsable de las explotaciones y se establece una jerarquía sobre cuáles son los objetivos empresariales y familiares que guían la actuación de dichos ganaderos. Finalmente, se analizan sus expectativas de futuro y mediante un modelo logit se determinan qué factores inciden sobre dichas expectativas...The sheep sector in Aragón can be characterized as a dual system. Together with traditional familiar businesses with a low rate of out-of-farm employment, an old infrastructure and a low level of investments, there have appeared in recent years a new dynamic sector characterized by larger sizes, more modern infrastructure, technological investments and the use of out-of-farm employment. The current crisis the sector is suffering together with the recent reform of the CMO have generated a high degree of uncertainty among sheep farmers about the future. The aim of this study is, precisely, to analyse the future expectations of sheep producers. From a survey carried out among a sample of sheep farmers producers representing the most important production systems within the region, this paper sociodemographically characterises the owner of the farms and establishes a ranking of their possible business and personal/familiar goals. Finally, future expectations are analysed and a logit model is specified to determine main factors for future survival.

description: Este trabajo trata de llamar la atención sobre el olvido del legislador fiscal respecto de la problemática del sector forestal, en cuanto a las exenciones o bonificaciones que se producen en los Impuestos directos en España. Y ello porque para que se produzcan esas exenciones o bonificaciones debe haber afección de los bienes a la actividad económica. En la actividad forestal en España no pueden cumplirse todos los requisitos, tales como la habitualidad, el ejercicio de la actividad de forma directa y personal y, sobre todo, la condición de principal fuente de ingresos, dado su especial tipo de producción...This paper attempts to draw attention to the taxation legislators’ indifference regarding the problems of the foresty activity as regards exemptions or allowances arising in Direct Tax in Spain. For these exemptions or allowances to arise the property must have been subject to economic activity. In the Spanish forestry activity not all the requirements can be fulfilled such as permanency, the carrying out of the activity in a direct and personal manner and, above all, the condition of the activity being the principal source of income, given its special kind of production.

La metodología empleada se basa en el análisis descriptivo y de impacto derivados de las propias tablas. A pesar de que las dos características fundamentales del sector hortofrutícola son, por una parte, el ser uno de los mayores sectores en producción y su marcada vocación exportadora, se aprecia cómo sus encadenamientos directos hacia delante y hacia detrás son débiles. Siguiendo la clasificación de Chenery-Watanabe se considera al sector hortofrutícola como producción primaria final, y tomando como referencia los coeficientes de Rasmusen se considera como independiente. Si tomamos en consideración el análisis de impactos se aprecia cómo el sector hortofrutícola debe ser considerado como una de las ramas más importantes de la economía andaluza por su efecto multiplicador tanto de producción, renta y empleo...The aim of this paper is studied the Andalusian horticultural through the input-output methodology. In this case, the methodology is based on the descriptive and impact analysis. Although the two fundamental characteristics of the andalusian horticultural are on one hand the being one of the biggest sectors in production and their marked vocation exporter is appreciated as their direct linkages toward before and toward behind they are weak. Following the classification of Chenery-Watanabe is considered to final primary production and taking like reference the coefficients of Rasmusen are considered as independent. If we take in consideration the analysis of impacts it is appreciated as the andalusian horticultural should be considered as one of the most important branches in the Andalusian economy by their effect so much multiplier of production, income and employment.

description: A new acceleration algorithm to address the problem of multiple time scales in variational Monte Carlo simulations is presented. After a first attempted move has been rejected, the delayed rejection algorithm attempts a second move with a smaller time step, so that even moves of the core electrons can be accepted. Results on Be and Ne atoms as test cases are presented. Correlation time and both average accepted displacement and acceptance ratio as a function of the distance from the nucleus evidence the efficiency of the proposed algorithm in dealing with the multiple time scales problem.

description: Explaining the evidence for surface liquid water on early Mars has been a challenge for climate modelers, as the sun was ~30% less luminous during the late-Noachian. We propose that the additional greenhouse forcing of CO2-H2 collision-induced absorption is capable of bringing the surface temperature above freezing and can put early Mars into a limit-cycling regime. Limit cycles occur when insolation is low and CO2 outgassing rates are unable to balance with the rapid drawdown of CO2 during warm weathering periods. Planets in this regime will alternate between global glaciation and transient warm climate phases. This mechanism is capable of explaining the geomorphological evidence for transient warm periods in the martian record. Previous work has shown that collision-induced absorption of CO2-H2 was capable of deglaciating early Mars, but only with high H2 outgassing rates (greater than ~600 Tmol/yr) and at high surface pressures (between 3 to 4 bars). We used new theoretically derived collision-induced absorption coefficients for CO2-H2 to reevaluate the climate limit cycling hypothesis for early Mars. Using the new and stronger absorption coefficients in our 1-dimensional radiative convective model as well as our energy balance model, we find that limit cycling can occur with an H2 outgassing rate as low as ~300 Tmol/yr at surface pressures below 3 bars. Our results agree more closely with paleoparameters for early martian surface pressure and hydrogen abundance.

Terrain Relative Navigation for Lunar Polar Roving: Exploiting Geometry, Shadows, and Planning

Publisher: name: Carnegie Mellon University

Subjects: subject: 80101 Adaptive Agents and Intelligent Robotics

description: Water ice at the lunar poles could be the most valuable resource beyond planet Earth. However, that value is not foregone, and can only be determined by rovers that evaluate the distributions of abundance, concentration, and characteristics of this ice. The near-term explorations will be solar and unlikely to endure night and hence are limited to a single cycle of lunar daylight. Sun-synchronous polar routes promise order-of-magnitude greater duration andrange. Such routes are, however, brittle in the sense that a rover must be at precisely scheduled time and place. Methods for terrain-based localization that workat low latitudes are challenged at the lunar poles, where the grazing sunlight casts long shadows that obscure and change views over time. Moreover, the cadence ofexploration driven by the clocking sun requires terrain localization to be highly informative. Technologies in these areas are lacking, which results in a level of risk that currently makes these missions not viable. This thesis develops methods for terrain relative navigation that enable the robust execution of sun-synchronous routes at the lunar poles. This research advances terrain registration under sensor and map uncertainty, exploits shadows as features for localization, and develops planning algorithms that increase information gain from terrain registration.There are four major contributions of this research. The first is a scan matching algorithm that probabilistically geometrically registers rover perspective stereoimages to a digital elevation map which is evaluated against priors in both simulated and real small-scale experiments. The second is an extension of the geometric method to exploit shadows as features. The third is a method of predicting the uncertainty of terrain-based localization given terrain geometry and lighting. The fourth is a belief space planning algorithm that maximizes the probability of surviving sunsynchronous exploration by considering when and where to perform terrain relative corrections. Together, these methods are evaluated for route robustness and mission risk within the developed simulation framework and with scale field data. The work developed in this thesis enables robust sun-synchronous routes for multi-month exploration and increased science return at the lunar poles.
Non-concave fundamental diagrams and phase transitions in a stochastic traffic cellular automaton

description: Within the class of stochastic cellular automata models of traffic flows, we look at the velocity dependent randomization variant (VDR-TCA) whose parameters take on a specific set of extreme values. These initial conditions lead us to the discovery of the emergence of four distinct phases. Studying the transitions between these phases, allows us to establish a rigorous classification based on their tempo-spatial behavioral characteristics. As a result from the system's complex dynamics, its flow-density relation exhibits a non-concave region in which forward propagating density waves are encountered. All four phases furthermore share the common property that moving vehicles can never increase their speed once the system has settled into an equilibrium.

description: In this paper, we compare the capabilities of two open source near-wall-modeled large eddy simulation (NWM-LES) approaches regarding prediction accuracy, computational costs and ease of use to predict complex turbulent flows relevant to internal combustion (IC) engines. The applied open source tools are the commonly used OpenFOAM, based on the finite volume method (FVM), and OpenLB, an implementation of the lattice Boltzmann method (LBM). The near-wall region is modeled by the Musker equation coupled to a van Driest damped Smagorinsky-Lilly sub-grid scale model to decrease the required mesh resolution. The results of both frameworks are compared to a stationary engine flow bench experiment by means of particle image velocimetry (PIV). The validation covers a detailed error analysis using time-averaged and root mean square (RMS) velocity fields. Grid studies are performed to examine the performance of the two solvers. In addition, the differences in the processes of grid generation are highlighted. The performance results show that the OpenLB approach is on average 32 times faster than the OpenFOAM implementation for the tested configurations. This indicates the potential of LBM for the simulation of IC engine-relevant complex turbulent flows using NWM-LES with computationally economic costs.

description: Four new acylphloroglucinol derivatives 1, 3, 5 and 13 were isolated from the fruits of Horsfieldia irya, and in addition, thirteen known compounds were also discovered. All compounds were evaluated for cytotoxicity against HeLa and HCT116 cell lines, as well as normal cells (Vero cells). Compound 13 showed cytotoxicity against HeLa and HCT116 cell lines with IC50 values of 4.53 ± 0.05 and 4.53 ± 0.16 μg/mL, respectively, and showed less activity against normal cells (IC50 = 13.38 ± 0.75 μg/mL). Compound 13 may be useful for the development of anticancer agents. It was found that decanoyl side chain may be necessary for the cytotoxicity. The chemical structures of all isolated compounds were elucidated using spectroscopic methods including 1 D-NMR, 2 D-NMR, MS and IR data.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: Pour lutter contre la montée de l’obésité, les pouvoirs publics ont depuis une dizaine d’années, mis en place des politiques visant à modifier les comportements alimentaires. En France, le ministère de la Santé a lancé en 2001 le Programme National Nutrition Santé (PNNS). L’essentiel des instruments de politiques mis en oeuvre vise à apporter de l’information aux consommateurs pour qu’ils fassent des choix plus « avisés » d’un point de vue nutritionnel. Cependant, les actions menées jusqu’à présent n’ont pas permis de stopper significativement la croissance de l’obésité. D’autres types d’instruments, visant à modifier l’environnement de marché des consommateurs, ont été peu utilisés. Parmi ceux-ci, la modification des prix via des taxes ou subventions est une option souvent débattue mais rarement mise en place. En Europe, plusieurs pays comme la Hongrie, la Finlande ou le Danemark ont introduit récemment des taxes sur les produits jugés délétères pour la santé. En France depuis le 1er Janvier 2012, les Boissons Rafraichissantes Sans Alcool (BRSA) sont taxées à hauteur de 7,16 centimes d’euros par litre. A partir de l’exemple de la France, nous présentons une synthèse des effets potentiels de la mise en oeuvre de taxes nutritionnelles. Comme il y a peu d’exemples de taxes nutritionnelles mises en place, la plupart des analyses de leur impact potentiel sur la consommation et sur la santé sont des analyses dites ex ante qui reposent sur des simulations. Les modèles utilisés, estimés sur des observations de consommation passées, permettent d’évaluer les changements de consommation induits par des changements de prix d’un ou plusieurs biens. Les travaux sur le cas français intègrent non seulement la réaction des consommateurs aux changements de prix des biens mais aussi, et c’est là sa principale originalité, l’impact de la mise en place de la taxe sur les prix des produits. En effet, les producteurs de boissons et les distributeurs peuvent répercuter partiellement la taxe en réduisant leurs marges, ou bien avoir intérêt à répercuter plus que le montant de la taxe sur le prix final en augmentant leurs marges. Nos travaux montrent que ces stratégies d’ajustement des prix dépendent du type de taxe mise en place. Ils permettent également d’évaluer l’impact des taxes sur la consommation de sucres par les boissons en intégrant les reports de consommation entre différents types de boissons.

description: How to revitalise the cattle and dairy sectors under the WTO commitments has emerged as a major policy challenge for the Russian government. This article raises the question whether livestock recovery in East Germany does provide any insights that could be of value to current policy makers in Russia. Similar to Russia, livestock numbers plummeted in the first years after the end of central planning. Unlike in Russia, milk output per cow increased spectacularly and almost doubled in a period of 20 years. It is argued that reforms of the institutional environment of agriculture were at least as important for this outcome as the generous availability of funding. Incentives set by financial aid were sometimes unintended, inconsistent, and led to misallocations that were costly to correct later on. More recent capital subsidies were inefficient in reaching any of the manifold goals they were hoped to achieve. While the Russian government may face little difficulty in dressing up its investment subsidies to make them look like green box compatible, the structural elements of the EU's Common Agricultural Policy are regarded as a poor guide for policy reform.

description: El objetivo del trabajo es el de proporcionar una visión transversal desde diferentes disciplinas sobre los orígenes de una cuestión fundamental que en la actualidad suscita controversias científicas y políticas de todo tipo: la creciente implicación del Estado español en el proceso de modernización agraria a través de la política de fomento a la irrigación. Para alcanzar este objetivo partimos de la caracterización del paradigma de gestión del agua durante el siglo XIX. Seguidamente, se enfatizan las repercusiones institucionales que tuvo la coyuntura de la crisis finisecular en materia de aguas y, por último, se incide en las perspectivas abiertas por la Administración estatal durante las décadas de 1920 y 1930 que no fueron retomadas, y de una forma sesgada, hasta la década de 1950...The aim of this research is to offer a sidelong vision from different disciplines on the origins of a fundamental question that arouses nowadays all kinds of political and scientific controversies: the growing implication of the Spanish state in the process of agricultural modernisation by means of a policy of irrigation support. To this effect, I shall begin by showing the paradigm of water management in the 19th century. After this, I will remark on the institutional repercussions brought about by the conjuncture of the turn-of-the-century water crisis and, finally, I shall deal with the perspectives that had been opened up by the State administration in the 1920s and 1930s and that were not taken up again, and in a biased way, until the 1950s.

Standing Waves in a Non-linear 1D Lattice : Floquet Multipliers, Krein Signatures, and Stability

description: We construct a class of exact commensurate and incommensurate standing wave (SW) solutions in a piecewise smooth analogue of the discrete non-linear Schrödinger (DNLS) model and present their linear stability analysis. In the case of the commensurate SW solutions the analysis reduces to the eigenvalue problem of a transfer matrix depending parametrically on the eigenfrequency. The spectrum of eigenfrequencies and the corresponding eigenmodes can thereby be determined exactly. The spatial periodicity of a commensurate SW implies that the eigenmodes are of the Bloch form, characterised by an even number of Floquet multipliers. The spectrum is made up of bands that, in general, include a number of transition points corresponding to changes in the disposition of the Floquet multipliers. The latter characterise the different band segments. An alternative characterisation of the segments is in terms of the Krein signatures associated with the eigenfrequencies. When one or more parameters characterising the SW solution is made to vary, one occasionally encounters collisions between the band-edges or the intra-band transition points and, depending on the the Krein signatures of the colliding bands or segments, the spectrum may stretch out in the complex plane, leading to the onset of instability. We elucidate the correlation between the disposition of Floquet multipliers and the Krein signatures, presenting two specific examples where the SW possesses a definite window of stability, as distinct from the SW's obtained close to the anticontinuous and linear limits of the DNLS model.

Tachyon Defect Formation and Reheating in Brane-Antibrane Inflation

description: We study analytically the dynamical formation of lower dimensional branes at the endpoint of brane-antibrane inflation through the condensation of topological defects of the tachyon field which describes the instability of the initial state. We then use this information to quantify the efficiency of the reheating which is due to the coupling of time dependent tachyon background to massless gauge fields which will be localized on the final state branes. We improve upon previous estimates indicating that this can be an efficient reheating mechanism for observers on the brane.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Superluminal hidden communication as the underlying mechanism for quantum correlations: constraining models

description: Since Bell's theorem, it is known that quantum correlations cannot be described by local variables (LV) alone: if one does not want to abandon classical mechanisms for correlations, a superluminal form of communication among the particles must be postulated. A natural question is whether such a postulate would imply the possibility of superluminal signaling. Here we show that the assumption of finite-speed superluminal communication indeed leads to signaling when no LV are present, and more generally when only LV derivable from quantum statistics are allowed. When the most general LV are allowed, we prove in a specific case that the model can be made again consistent with relativity, but the question remains open in general.

Time course of nigro-striatal neurodegeneration : a novel toxin-induced model showing neuropathological features of parkinsonism
Creators: name: Schulz, Jeff

description: Amyotrophic lateral sclerosis-parkinsonism dementia complex (ALS-PDC) is a neurodegenerative disease characterized by features of amyotrophic lateral sclerosis, parkinsonism, and a dementia reminiscent of Alzheimer's disease. Occurring primarily on the island of Guam, it has been linked epidemiologically to the consumption of seeds from the cycad palm Cycas micronesica. To further investigate the 'cycad hypothesis' of ALS-PDC, a cycad model has been developed in which mice are fed cycad as prepared by the indigenous people of Guam. Initial studies have shown that cycad-fed mice develop motor, cognitive and neuropathological changes similar to those of ALS-PDC. This study was designed to assess changes related to parkinsonism by investigating motor dysfunction and neuropathological changes related to dopamine in the basal ganglia. Cycad-fed animals demonstrated dysfunction in several motor tests, including the de Medinaceli gait length task. However, it was not possible to confirm that the motor phenotype was a result of dysfunction of the basal ganglia because of the potentially confounding effect of motor neuron involvement. Neuropathological analysis revealed a slow, progressive change in striatal dopaminergic integrity as evidenced by decreases in striatal tyrosine hydroxylase and dopamine transporter immunoreactivity as well as a compensatory increase in dopamine D2 receptor levels. Analysis of apopototic cell death showed the presence of activated caspase-3 dopaminergic cells in the substantia nigra pars compacta which was accompanied by astrogliosis. Notably, these neuropathological changes persisted despite the cessation of cycad feeding. In a subsequent experiment, measurement of striatal dopamine levels failed to detect a difference in cycad-fed animals, although this may be due to the fact that the tissue might have been collected before any significant neuropathological changes had occurred. Taken together, the results of this study provide further support for the 'cycad hypothesis' of ALS-PDC and show that features of parkinsonism are present in the cycad model.
