Recolonizing Ecuador's Oriente : oil, agriculture, and the myth of empty lands
Creators: name: Gaechter, Darcy Ann
Publisher: name: University of British Columbia
Year: 2011

description: Multi-national oil corporations, the national government, landless Ecuadorian farmers, and Ecuador's Indigenous populations have dramatically transformed the eastern half of Ecuador (the Oriente) over the past forty years. When American oil companies Texaco and Gulf discovered viable oil wells in the region in 1968, they not only piqued the economic hopes of the Ecuadorian government, but also put into motion a massive modernization and recolonization movement. When Ecuadorian colonist Solomon Haro Valle traveled from the highland town of Ambato to the Oriente he described an inhospitable jungle, primitive living conditions, unbearable heat, and ominous jungle fauna. Yet hundreds of thousands of landless Ecuadorians moved to the Oriente during this period in order to cash in on the free land their government was giving away. Since the Ecuadorian government was desperately trying to bring this region under national control, it eagerly perpetuated the scenario that Haro described in order to transform the Oriente into a tierra baldia, or empty land in order to then transform it into an economically productive and integrated part of the Ecuadorian Nation. Through various laws and propaganda, the government effectively erased the Oriente's inhabitants (both Indigenous and Ecuadorian), and created the myth of the Oriente as a vacant space. It was only logical, then, to fill this empty space with Ecuadorian farmers who were willing to work towards the nation's latest modernization project—that of incorporating the Oriente along with its burgeoning oil industry.

description: Classically, the dynamics in a non-globally hyperbolic spacetime is ill posed. Previously, a prescription was given for defining dynamics in static spacetimes in terms of a second order operator acting on a Hilbert space defined on static slices. The present work extends this result by giving a similar prescription for defining dynamics in stationary spacetimes obeying certain mild assumptions. The prescription is defined in terms of a first order operator acting on a different Hilbert space from the one used in the static prescription. It preserves the important properties of the earlier one: the formal solution agrees with the Cauchy evolution within the domain of dependence, and smooth data of compact support always give rise to smooth solutions. In the static case, the first order formalism agrees with second order formalism (using specifically the Friedrichs extension). Applications to field quantization are also discussed.

description: Continuous gravity-fed column experiments using the methylene blue (MB) discoloration method were performed to characterize the suitability of a pozzolan (PZ) specimen as alternative admixing aggregate for metallic iron filters (Fe0-filters). Investigated systems were: (i) pure sand, (ii) pure PZ, (iii) pure Fe0, (iv) Fe0/sand, (v) Fe0/PZ, and (vi) Fe0/sand/PZ. The volumetric proportion of Fe0 was 25%. The volumetric proportions of the Fe0/sand/PZ system was 25/45/30. The initial MB concentration was 2.0 mg L􀀀1, 6.0 g of Fe0 was used, and the experiments lasted for 46 days. The individual systems were fed with 3.9 to 8.4 L (7.80 to 16.69 mg of MB) and were characterized by the time-dependent changes of: (i) the pH value, (ii) the iron breakthrough, (iii) the MB breakthrough, and (iv) the hydraulic conductivity. Results showed that the Fe0/sand/PZ system was the most efficient. This ternary system was also the most permeable and therefore the most sustainable. The suitability of MB as a powerful operative indicator for the characterization of processes in the Fe0/H2O system was confirmed. The tested PZ is recommended as an alternative material for efficient but sustainable Fe0 filters.

description: Adaptive learning technology solutions often use a learner model to trace learning and make pedagogical decisions. The present research introduces a formalized methodology for specifying learner models, Logistic Knowledge Tracing (LKT), that consolidates many extant learner modeling methods. The strength of LKT is the specification of a symbolic notation system for alternative logistic regression models that is powerful enough to specify many extant models in the literature and many new models. To demonstrate the generality of LKT, we fit 12 models, some variants of well-known models and some newly devised, to 6 learning technology datasets. The results indicated that no single learner model was best in all cases, further justifying a broad approach that considers multiple learner model features and the learning context. The models presented here avoid student-level fixed parameters to increase generalizability. We also introduce features to stand in for these intercepts. We argue that to be maximally applicable, a learner model needs to adapt to student differences, rather than needing to be pre-parameterized with the level of each student's ability.

Dynamic Kibble-Zurek scaling framework for open dissipative many-body systems crossing quantum transitions

description: We study the quantum dynamics of many-body systems, in the presence of dissipation due to the interaction with the environment, under Kibble-Zurek (KZ) protocols in which one Hamiltonian parameter is slowly, and linearly in time, driven across the critical value of a zero-temperature quantum transition. In particular we address whether, and under which conditions, open quantum systems can develop a universal dynamic scaling regime similar to that emerging in closed systems. We focus on a class of dissipative mechanisms whose dynamics can be reliably described through a Lindblad master equation governing the time evolution of the system's density matrix. We argue that a dynamic scaling limit exists even in the presence of dissipation, whose main features are controlled by the universality class of the quantum transition. This requires a particular tuning of the dissipative interactions, whose decay rate $u$ should scale as $u\sim t_s^{-κ}$ with increasing the time scale $t_s$ of the KZ protocol, where the exponent $κ= z/(y_μ+z)$ depends on the dynamic exponent $z$ and the renormalization-group dimension $y_μ$ of the driving Hamiltonian parameter. Our dynamic scaling arguments are supported by numerical results for KZ protocols applied to a one-dimensional fermionic wire undergoing a quantum transition in the same universality class of the quantum Ising chain, in the presence of dissipative mechanisms which include local pumping, decay, and dephasing.

description: This memoir deals with the hypoelliptic calculus on Heisenberg manifolds, or Heisenberg calculus. The Heisenberg manifolds generalize CR and contact manifolds and in this context the main differential operators at stake include the Hörmander's sum of squares, the Kohn Laplacian, the horizontal sublaplacian and its conformal powers and the contact Laplacian. These operators cannot be elliptic and the relevant pseudodifferential calculus to study them is provided by the Heisenberg calculus. The aim of this monograph is threefold. First, we give an intrinsic approach to the Heisenberg calculus by finding an intrinsic notion of principal symbol in this setting. This framework allows us to prove that the pointwise invertibility of a principal symbol, which can be restated in terms of the so-called Rockland condition, actually implies its global invertibility. Second, we study complex powers of hypoelliptic operators on Heisenberg manifolds in terms of the Heisenberg calculus. In particular, we show that complex powers of such operators give rise to holomorphic families in the Heisenberg calculus and we construct a scale of weighted Sobolev spaces providing us with sharp estimates for the operators in the Heisenberg calculus. Third, we make use of the Heisenberg calculus and of the results of this monograph to derive spectral asymptotics for hypoelliptic operators on Heisenberg manifolds. The advantage of using the Heisenberg calculus is illustrated by reformulating in a geometric fashion these asymptotics for the main geometric operators on CR and contact manifolds.

Elastic turbulence in curvilinear flows of polymer solutions

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: Following our first report (A. Groisman and V. Steinberg, $\sl Nature$ $\bf 405$, 53 (2000)) we present an extended account of experimental observations of elasticity induced turbulence in three different systems: a swirling flow between two plates, a Couette-Taylor (CT) flow between two cylinders, and a flow in a curvilinear channel (Dean flow). All three set-ups had high ratio of width of the region available for flow to radius of curvature of the streamlines. The experiments were carried out with dilute solutions of high molecular weight polyacrylamide in concentrated sugar syrups. High polymer relaxation time and solution viscosity ensured prevalence of non-linear elastic effects over inertial non-linearity, and development of purely elastic instabilities at low Reynolds number (Re) in all three flows. Above the elastic instability threshold, flows in all three systems exhibit features of developed turbulence. Those include: (i)randomly fluctuating fluid motion excited in a broad range of spatial and temporal scales; (ii) significant increase in the rates of momentum and mass transfer (compared to those expected for a steady flow with a smooth velocity profile). Phenomenology, driving mechanisms, and parameter dependence of the elastic turbulence are compared with those of the conventional high Re hydrodynamic turbulence in Newtonian fluids.

title: Economic and social change in Wensleydale and Swaledale in the nineteenth century
Creators: name: Hallas, Christine Sarah
Publisher: name: The Open University
Year: 1988

description: Although rural areas share certain common characteristic's, individual districts and their communities exhibit many important differences. This study provides a detailed analysis of economic and social change in the nineteenth century in a specific rural upland area in the north Yorkshire Pennines. It is intended both to add to r the limited body of detailed knowledge which already exists in respect of rural, and specifically upland rural, areas and to test generalizations concerning the economic and social structure of such areas against the individual experience of Wensleydale and Swaledale. The major industries of the two dales in the nineteenth century, agriculture, mining, and textiles, formed the basis of the economy of many upland areas. The development and relative importance of these industries within Wensleydale and Swaledale is closely examined and compared with other areas in order to identify the uniqueness or otherwise of the extent and direction of change within the dales. The influence of local and non-local factors on the demise of two of these industries in the nineteenth century and on the structural changes in the third is also studied. The survival of upland areas in an increasingly industrialized and competitive society was constrained by inaccessibility. The extent to which road and rail transport assisted the two dales to overcome the problems of isolation is, therefore, examined. Although the present work is an economic and social study, it concerns itself primarily with economic change since a healthy economy was essential for the maintenance of a viable local community. The social condition of the community is studied in the context of its response to the rapidly changing economy in the nineteenth century. In particular, a detailed analysis is undertaken of the extent to which population growth and decline, and attendant migration, affected the well-being of the local community.

description: Sponges and coralomorphs were sessile epibenthic suspension feeders living in normal marine environments. Sponges with calcified skeletons, induding archaeocyaths, mainly inhabited shallow to subtidal and intertidal domains, while other sponges occupied a variety of depths, including slopes. The high diversity .of sponges in many Cambrian Lagerstätten suggests that complex tiering and niche partitioning were established early in the Cambrian. Hexactinellida were widespread in shallow-water conditions from the Tommotian; some of them may have been restricted to deepwater environments later in the Cambrian. Calcareans (pharetronids), together with solitary coralomorphs, thrived in reef environments, mostly in cryptic niChes protected from very agitated waters. Rigid demosponges (anthaspidellids and possible axinellids) appeared by the end of the Early Cambrian and inhabited hardgrounds and reefs from the Middle Cambrian. The overall diversity of sponge and coralomorph types indicates that during the Cambrian these groups, like other metazoans, evolved a variety of architectural fonns not observed in subsequent periods.

description: We present a detailed study of a three-level quantum heat engine operating at maximum efficient power function, a trade-off objective function defined by the product of the efficiency and power output of the engine. First, for near equilibrium conditions, we find general expression for the efficiency and establish universal nature of efficiency at maximum power and maximum efficient power. Then in the high temperature limit, optimizing with respect to one parameter while constraining the other one, we obtain the lower and upper bounds on the efficiency for both strong as well as weak matter-field coupling conditions. Except for the weak matter-field coupling condition, the obtained bounds on the efficiency exactly match with the bounds already known for some models of classical heat engines. Further for weak matter-field coupling, we derive some new bounds on the the efficiency of the the engine which lie beyond the range covered by bounds obtained for strong matter-field coupling. We conclude by comparing the performance of our three-level quantum heat engine in maximum power and maximum efficient power regimes and show that the engine operating at maximum efficient power produces at least $88.89\%$ of the maximum power output while considerably reducing the power loss due to entropy production.

description: A general appearance of two-pole structures is exhibited in a relativistic Friedrichs-Lee model combined with a relativistic quark pair creation model in a consistent manner. This kind of two-pole structure could be found when a $q\bar q$ state couples to the open-flavor continuum state in the $S$ partial wave. We found that many enigmatic states, such as $f_0(500)/σ$, $K_0^*(700)/κ$, $a_0(980)$, $f_0(980)$, $D_0^*(2300)$, $D_{s0}^*(2317)$, and $X(3872)$, together with another higher state for each, all result from this kind of two-pole structures. Furthermore, an interesting observation is that this kind of two-pole structure will contribute roughly a total of 180$^\circ$ phase shift for the scattering process in a single channel approximation. This relativistic scheme may provide more insights into the understanding of the properties of non-$q\bar q$ state. It is also suggested that such two-pole structure could be a common phenomenon which deserves studying both from theoretical and experimental perspectives.

description: Value-at-risk is one of the important subjects that extensively used by researchers and practitioners for measuring and managing uncertainty in financial markets. Although value-at-risk is a common risk control instrument, but there are criticisms about its performance. One of these cases, which has been studied in this research, is the value-at-risk underestimation during times of crisis. In these periods, the non-Gaussian behavior of markets intensifies and the estimated value-at-risks by normal models are lower than the real values. In fact, during times of crisis, the probability density of extreme values in financial return series increases and this heavy-tailed behavior of return series reduces the accuracy of the normal value-at-risk estimation models. A potential approach that can be used to describe non-Gaussian behavior of return series, is Tsallis entropy framework and non-extensive statistical methods. In this paper, we have used non-extensive value at risk model for analyzing the behavior of financial markets during times of crisis. By applying q-Gaussian probability density function, we can see a better value-at-risk estimation in comparison with the normal models, especially during times of crisis. We showed that q-Gaussian model estimates value-at-risk better than normal model. Also we saw in the mature markets, it is obvious that the difference of value-at-risk between normal condition and non-extensive approach increase more than one standard deviation during times of crisis, but in the emerging markets we cannot see a specific pattern.

description: Another push to deploy GPS dive loggers on Yellow-eyed penguins from the Catlins was made in late January. The dire situation of breeding birds in the region turned out to be a major stumbling block for this endeavour as many of the nests intended for deployment at Hinahina Cove had failed so that only a single deployment was made on one of the last two remaining breeding females on 22 January 2019. Recovery of the device was attempted between 6pm and 11pm each day from 29 January and 5 February 2019. However, the penguin did not return on any of these days. On 30 January the two remaining nests at Hinahina Cove dissolved when all chicks – grossly underweight – were transferred to Dunedin for rehab. There is still hope that the device can be recovered when the bird returns to Hinahina Cove to moult. At Te Rere, on the 22 January 2019 a GPS dive logger and camera logger were deployed on the penguin that had exhibited linear foraging in December. Both its chicks are in good conditions and belong to the very small group of chicks not transferred to rehab. Recovery attempts began on 23 January 2019; the bird was recaptured, and devices were recovered on 25 January 2019. The bird had spent three days out at sea foraging in a region some 25 km from Te Rere consistently diving to 90-100m depths. The camera logger only yielded poor video data as the device’s lens cap leaked water which compromised image quality and destroyed the image sensor 35 minutes after recording had started. After these deployments it was decided to cease activities in the Catlins for the time being and instead focus on hoiho from the Otago Peninsula and Aramoana. On 11 and 12 February, two female hoiho were captured and fitted with a GPS dive logger at Cicely Beach (Otapahi). On 16 and 17 February, a total of five penguins were fitted with devices at Aramoana.
title: The relationship of the son to the father in Justin Martyr
Creators: name: Herbert, John
Publisher: name: The Open University
Year: 1979

description: The Introduction contains a discussion on the manuscripts of the works of Justin Martyr and draws attention to inaccuracies in previous authors. The texts of recent editors have been considered and the works of even more recent scholars on Justin have been assessed. To set the entire book in perspective has needed a general comment and this has involved a consideration of the sitz im leben of the works of Justine. We tried to describe the being of God as we thought Justin imagined Him, Middle Platonist as our author was. We failed to find here the person of a beloved Father who cared deeply in a profoundly personal way for his children. Retribution seemed to be the way in which the Supreme Principle commanded obedience. The Incarnation of the Christ-Locos also drew upon the concepts of Middle Platonism. We were inclined to associate a Subordinate Son with ideas of the Gnostics and could not find escape from a conclusion that an intimate relationship between the Son and the Father played an insignificant part in Redemption. The sacrifice of Christ was interpreted as a penal substitution where there was some exorcistic; stress on the nature of the sacrifice. Although Christ was a Mediators there were elements present of magic exorcism and certainly Gnostic ideas. The will of God was the greatest element in the relationship between the Father and the Son. We concluded that the tolerance for Gnostic ideas was so great in Justin that there were serious implications for what was considered 'orthodoxy' in the second century A.D.

Relativistic Collapse of Rotating Supermassive Stars to Supermassive Black Holes

description: There is compelling evidence that supermassive black holes (SMBHs) exist. Yet the origin of these objects, or their seeds, is still unknown. We are performing general relativistic simulations of gravitational collapse to black holes in different scenarios to help reveal how SMBH seeds might arise in the universe. SMBHs with ~ 10^9 solar masses must have formed by z > 6, or within 10^9 yrs after the Big Bang, to power quasars. It may be difficult for gas accretion to build up such a SMBH by this time unless the initial seed black hole already has a substantial mass. One plausible progenitor of a massive seed black hole is a supermassive star (SMS). We have followed the collapse of a SMS to a SMBH by means of 3D hydrodynamic simulations in post-Newtonian gravity and axisymmetric simulations in full general relativity. The initial SMS of arbitrary mass M in these simulations rotates uniformly at the mass--shedding limit and is marginally unstable to radial collapse. The final black hole mass and spin are determined to be M_h/M ~ 0.9 and J_h/M_h^2 ~ 0.75. The remaining mass goes into a disk of mass M_{disk}/M ~ 0.1. This disk arises even though the total spin of the progenitor star, J/M^2 = 0.97, is safely below the Kerr limit. The collapse generates a mild burst of gravitational radiation. Nonaxisymmetric bars or one-armed spirals may arise during the quasi-stationary evolution of a SMS, during its collapse, or in the ambient disk about the hole, and are potential sources of quasi-periodic waves, detectable by LISA.

description: Zika virus is part of the flaviviruses that spread through the Aedes mosquito species and causes neurological infectious diseases. The non-structural protein 1 (NS1) is an essential enzyme that is involved in the replication of Zika virus. In this study, the newly isolated flavonoid analogs were docked against the NS1 protein. Most of the compounds showed strong interactions with favorable binding energies in the active site of NS1. One of the suitable docked ligand-protein complexes was simulated along with the apo form of the enzyme for 100 ns. The simulation results validated the docking data. The molecular dynamics simulation analysis comprising of root mean square deviation and fluctuation, the radius of gyration, hydrogen bonding, potential energy, principle component analysis, and MM/PBSA revealed about the stability of the apo and complex systems. These flavonoids analogs can inhibit the hexamerization of the NS1 which is necessary for the Zika virus replication. Communicated by Ramaswamy H. Sarma

DISTRIBUTION. — Philippines, Indonesia, New Caledonia, Loyalty Islands, New Hebrides Arc, Wallis and Futuna, Vanuatu, Fiji Islands, Tonga, Austral Islands and Marquesas Islands (Dijkstra & Maestrati 2010: 344). Depth range 581-2000 m (alive). Now also Society Islands and Tuamotu Archipelago (new record), single valves at 887-1145 m (maximum depth range).
REMARKS
 The present specimens of Pseudohinnites levii are similar to the type material from New Caledonia, although the vesicular lamellae on the radial lirae of the left valve are more widely spaced and the interliral spaces are almost smooth or with very weak commarginal lamellae (typical with closely spaced prominent commarginal lamellae).Other characters are indistinguishable from the type material.

description: We introduce Partially Coherent Direct Sum (PCDS) quantum channels, as a generalization of the already known Direct Sum quantum channels. We derive necessary and sufficient conditions to identify the subset of those maps which are degradable, and provide a simplified expression for their quantum capacities. Interestingly, the special structure of PCDS allows us to extend the computation of the quantum capacity formula also for quantum channels which are explicitly not degradable (nor antidegradable). We show instances of applications of the results to dephasing channels, amplitude damping channels and combinations of the two.

description: Between 21 December 2018 and 4 January 2019, a total of six breeding hoiho carried GPS dive loggers. Of these, only three devices could be recovered. One penguin managed to preen off the device while at sea shortly after deployment. Two devices were lost because recapture of the penguins proved very difficult. As a result, deployment periods were extended by more than a week facilitating device loss. Of the three recovered devices, the GPS unit of one device was destroyed as the penguin pierced the casing causing leakage; this did not affect dive data, though. The other units yielded full GPS and data sets. Tracking data from Penguin Bay, highlight increased foraging effort with the penguin performing several overnight trips during which it visited the edge of the continental shelf. At Te Rere, the situation was markedly different with birds performing one-day and short-term trips. GPS data indicates interaction with inshore fisheries, as the penguin performed several trips during which it exhibited linear foraging which is generally associated with bottom trawl fisheries.

description: Protein components found in freeze-dried specimens of the coralline sponge Spirastrella (Acanthochaetetes) wellsi were separated and characterized . Proteins extracted from skeleton crystals (matrix proteins) contained high concentrations of glycin (16 %) as weil as enhanced amounts of asparagin/aspartic acid (11 %) and glutamin/glutamic acid (10 %). At least 10 proteins could be separated by SDSPAGE. Six of them, with molecular weights between 30 and 45 kDa, may be considered as distinct matrix proteins. The bulk of total soluble proteins as weil as all soluble matrix proteins are acidic with pH values below 5. Our results indicate that at least in one stage crystal growth is matrix mediated, i.e. controlled by the sponge.
Evidence for Harmonic Content and Frequency Evolution of Oscillations during the Rising Phase of X-ray Bursts from 4U 1636-536

description: We report on a study of the evolution of burst oscillation properties during the rising phase of X-ray bursts from 4U 1636--536 observed with the proportional counter array (PCA) onboard the Rossi X-Ray Timing Explorer (RXTE). We present evidence for significant harmonic structure of burst oscillation pulses during the early rising phases of bursts. This is the first such detection in burst rise oscillations, and has interesting implications for constraining neutron star structure parameters and the equation of state models of matter at the core of a neutron star. The detection of harmonic content only during the initial portions of the burst rise appears consistent with the theoretical expectation that with time the thermonuclear burning region becomes larger, and hence the fundamental and harmonic amplitudes both diminish. We also find, for the first time from this source, strong evidence of frequency increases during burst rise. The timing behavior of harmonic content, amplitude, and frequency of burst rise oscillations may be important in understanding the spreading of thermonuclear flames under the extreme physical conditions on neutron star surfaces.

Quellen und Vorkommen kurzkettiger Alkylphenole (SCAP)

description: Aus der Literaturrecherche und eigenen Untersuchungen geht hervor, dass kurzkettige Alkylphenole (SCAP) während der Verarbeitungs- bzw. Veredelungsprozesse fester fossiler Brennstoffe ebenso in die Umwelt freigesetzt werden können, wie basierend auf Prozessen verschiedenster Industrien. Die große Bandbreite an Verwendungs- und Anwendungsmöglichkeiten von SCAP bringt viele Eintragsmöglichkeiten in die Umweltmedien mit sich. Prägnant sind die prozessbedingten SCAP-Muster (vorkommende Einzelsubstanzen) der verschiedenen Industrien und Produkte, wodurch Eintragsquellen und Fließpfade genauer quantifiziert werden können. Natürliche Eintragsquellen von SCAP mit Konzentrationen bis zu mehreren Tausend ppm sind ausschließlich Erdöle bzw. erdölführende Gesteine. Dieser Sachverhalt in Verbindung mit ihren chemisch-physikalischen Eigenschaften begründet die Verwendung der SCAP als Fluss- und Prozessindikatoren in der Erdöl-Reservoir-Erkundung und -Förderung. Anlehnend daran ist der oft noch fehlende Kenntnisstand der Umweltrelevanz und -akzeptanz von SCAP in Grundwasser-Schadensfällen in Deutschland nicht nachzuvollziehen. Es wird verdeutlicht, dass SCAP neben Erdölreservoiren auch für den Wasserkreislauf als Fluss- und Prozessindikatoren prädestiniert sind.

description: This report presents statistical analyses of data on teachers’ professional development (PD) in the international studies TALIS, TIMSS, PIRLS, and PISA during the period 2001-2018. Thus, the report covers all international studies which contain data on Swedish teachers’ PD participation that enables comparisons over time. The report shows that the proportion of Swedish teachers that participated in PD has increased since 2001 according to all international studies. Likewise, the international average of the proportion of teachers that participated in PD has increased over time, although less sharply than for Swedish teachers. Based on figures in TALIS, the report shows that the amount of Swedish teachers’ PD participation is about 3-4 days per year, whereas the international average is about 6-9 days per year. The report also indicates that proportion of Swedish teachers that participated in PD is lower than the international average.According to TALIS, Swedish teachers’ participation in professional development is lower for teachers in privately managed schools than for teachers in publicly managed schools.Based on TIMSS and PIRLS, Swedish teachers are estimated to participate about one day per year in PD specific for each school subject that they teach. This is about the same as the international average for subject-specific PD reported in PIRLS and TIMSS grade 8. The international average for TIMSS grade 4 is lower than for Swedish teachers.

description: Online Arabic cursive character recognition is still a big challenge due to the existing complexities including Arabic cursive script styles, writing speed, writer mood and so forth. Due to these unavoidable constraints, the accuracy of online Arabic character's recognition is still low and retain space for improvement. In this research, an enhanced method of detecting the desired critical points from vertical and horizontal direction-length of handwriting stroke features of online Arabic script recognition is proposed. Each extracted stroke feature divides every isolated character into some meaningful pattern known as tokens. A minimum feature set is extracted from these tokens for classification of characters using a multilayer perceptron with a back-propagation learning algorithm and modified sigmoid function-based activation function. In this work, two milestones are achieved; firstly, attain a fixed number of tokens, secondly, minimize the number of the most repetitive tokens. For experiments, handwritten Arabic characters are selected from the OHASD benchmark dataset to test and evaluate the proposed method. The proposed method achieves an average accuracy of 98.6% comparable in state of art character recognition techniques.

The role of spurions in Higgs-less electroweak effective theories

description: Inspired by recent developments of moose models we reconsider low-energy effective theories of Goldstone bosons, gauge fields and chiral fermions applied to low-energy QCD and to Higgs-less electroweak symmetry breaking. Couplings and the corresponding reduction of symmetry are introduced via constraints enforced by a set of non-propagating covariantly constant spurion fields. Relics of the latter are used as small expansion parameters conjointly with the usual low-energy expansion. Certain couplings can only appear at higher orders of the spurion expansion and consequently, they become naturally suppressed independently of the idea of dimensional deconstruction. At leading order this leads to a set of generalized Weinberg sum rules and to the suppression of non-standard couplings to fermions in Higgs-less EWSB models with the minimal particle content. Within the latter, higher spurion terms allow for a fermion mass matrix with the standard CKM structure and CP violation. In addition, Majorana masses for neutrinos are possible. Examples of non-minimal models are briefly mentioned.

description: With NAFTA complete, Mexico and the U.S. must look beyond tariff and quota elimination to foster growth in agricultural trade. Simplifying border processes to make trade more agile would allow products to cross more quickly. To solicit ideas for doing so, this report's authors conducted about 80 interviews with people from the private sector, government, and academia in both countries.
