description: O modelo de agricultura ainda praticado continua a causar impactos negativos como a perda de solo, erosão genética, contaminação do solo e da água entre muitos outros efeitos. Considerando-se esse cenário e assim buscar minimizar estes processos, foi criada a Política Nacional de Assistência Técnica e Extensão Rural – PNATER, que orienta uma extensão rural baseada nos princípios epistemológico da agroecologia. Entre as mudanças, está à exigência de um novo perfil de extensionista, uso de metodologias participativas, minimização de utilização de recursos externos à propriedade, e a produção de vegetais e animais com a mínima degradação dos recursos naturais. O presente trabalho tem por objetivo analisar se essas mudanças estão sendo efetivamente empregadas pela Empresa Mato-grossense de Pesquisa, Assistência e Extensão Rural - EMPAER-MT. Utilizou-se como recorte para essa análise a atuação da EMPAER no Assentamento Guapirama, município de Campo Novo do Parecis, MT. A metodologia empregada foi a observação sistemática e não participante, entrevistas com produtores e técnicos. O resultado dessa análise denotou que a unidade da EMPAER-MT não está atuando conforme orienta a PNATER, em função de uma série de fatores que dificultam a ação extensionista rumo a uma transição agroecológica dos sistemas produtivos no Assentamento Guapirama.---------------------------------------------The agriculture model practiced nowadays is causing negative impacts such as losed of soil, genetic erosion, soil and water contamination and several other effects. Taking care that fact and thus seek to minimize these processes, was created the National Policy Technical Assistance and Rural Extension - PNATER, for to manage a rural extension based on the agroecology principles. Among the changes is the requirement for a new extensionist profile, use of participatory methodologies a decrease in the use of, external resources to the ownership, and plants and animal production with a minimal degradation of natural resources. This study aims to examine whether these changes are being effectively used by the searching Mato-grossense, Assistance and Rural extension company - EMPAER-MT. It was used as a cut for the actions of this analysis EMPAER in Assentamento Guapirama, municipality of Campo Novo do Parecis, MT. The methodology used was the systematic observation and not participating, interviews with producers and technicians. The result of that analysis got that EMPAER-MT is not acting as guides the PNATER.

description: In this paper we discuss how the peculiar properties of twisted lattice QCD at maximal twist can be employed to set up a consistent computational scheme in which, despite the explicit breaking of chiral symmetry induced by the presence of the Wilson and mass terms in the action, it is possible to completely bypass the problem of wrong chirality and parity mixings in the computation of the CP-conserving matrix elements of the $ΔS=1,2$ effective weak Hamiltonian and at the same time have a positive determinant for non-degenerate quarks as well as full O($a$) improvement in on-shell quantities with no need of improving the lattice action and the operators.

Structuring collaboration amongst B.C. First Nations and local governments : learning from Katzie First Nation and neighbouring local governments
Creators: name: Wells, Marlene
Publisher: name: University of British Columbia
Year: 2009

description: First Nations and local government communities in urban areas in British Columbia find themselves living in close proximity to each other as a result of urban growth. Local governments are becoming concerned about the impacts final treaty settlements will have on their communities. In general, they are unsure about the effects increased self-governing powers will have on their communities. In order for treaty implementation to be successful and, for First Nations and local government communities to co-exist in urban areas, it is necessary for these two parties to develop collaborative relationships. The main objectives of this research were to identify ways First Nations and local governments could collaborate on planning matters and to contribute to the literature on First Nation and local government planning relationships in BC. A framework of opportunities and obstacles to structuring collaboration among a First Nation and local government was developed by interviewing individuals from Katzie First Nation and neighbouring local governments. A discussion on the need for both parties to be motivated by a critical interest to structure collaboration is included in the framework. For the current study, the critical interest for the two parties stems from Katzie's treaty negotiations. The study found five key elements that together increase the opportunity for First Nations and local governments to structure collaboration. These are First Nation participation in the BC treaty process, face to face communication, mutual learning, First Nation participation in neighbouring community events, and informed municipal leaders on First Nation issues. The study identified the following four obstacles to collaboration: First Nations and local governments inability to negotiate at the treaty table, competing land use and development, relative government and administrative capacity, and lack of legislation requiring First Nations to consult with local governments. The framework considers issues that are specific to urban areas in BC where First Nations are negotiating treaties and how these issues affect collaboration among First Nations and local governments. The opportunities are consistent with the general principles of collaborative planning. It is concluded that the BC treaty process, in this case, acts as a catalyst in bringing these two parties together in long term dialogue and eventual collaboration.

description: Network virtualization is a way to simultaneously run multiple heterogeneous architectures on a shared substrate. The main issue in network virtualization is mapping virtual networks to substrate network. How to manage substrate resources in mapping phase will have an effective role in improving the use of infrastructure resources. Using software-based networks in network virtualization which separates control logic from data as a new technology, has led to efficient resource management in this context. In this article a software-based network approach has been presented to network virtualization and manage infrastructure resources efficiently. It optimizes mapping function by dynamic resource management of infrastructure resource. We have added a module in the controller to manage the resources dynamically. An initial mapping will be done for arriving new requests based on number of successful requests and arriving time slots. They will not be finalized by writing the rules in the switches before arriving n requests. If some remapping during the n time window is needed, remapping can be done by the controller and the final results are sent to the switches to write the flow rules. The simulation has been done using NS2 simulator showed based on different evaluation criteria such as acceptance rate, average link utilization, cost and delay. Keywords: network virtualization, software based network, Virtual network mapping, substrate network, Virtual network.

description: Este trabalho procurou identificar como os atores sociais vinculados à agricultura familiar (lideranças de produtores familiares, profissionais de ciências agrárias, autoridades municipais, pesquisadores e professores universitários) interpretam o papel do Estado para o desenvolvimento dessa categoria na Região Sul de Minas Gerais. Com relação à coleta de dados, utilizou-se a técnica "focused interview". Os entrevistados foram selecionados pelo método não-probabilístico de amostragem por julgamento. Os resultados revelaram que a interpretação feita pelos entrevistados aproxima-se mais da perspectiva do Estado patrimonialista burocrático autoritário, uma vez que os depoimentos apontam para a necessidade de uma maior intervenção do Estado. Por outro lado, alguns atores reconhecem a necessidade de uma estruturação do espaço público não-estatal, no entanto, salientaram que a mobilização dos produtores familiares na região ainda é incipiente e desarticulada. --------------------------------------------This work tried to identify how the social individuals linked to family agriculture (leadership of familiar producers, professionals of agrary sciences, town authorities, researchers and university professors) play the role of the State for the development of this category in the South Region of Minas Gerais. In relation to the data collection, the technique called “focused interview” was used. The interviewees were selected by the non probabilistic sampling by judgement method. The results revealed that the interpretation done by the interviewees is closest to the patrimonialistic bureaucratic authoritative State’s perspective, as the statements suggest a bigger State’s intervention. On the other side, some individuals recognize the necessity of a better structure of the non State public space, although mentioning that the familiar producers’ mobilization in the region is still incipient and inarticulate.

description: Advances in complex oxide heteroepitaxy have highlighted the enormous potential of utilizing strain engineering via lattice mismatch to control ferroelectricity in thin-film heterostructures. This approach, however, lacks the ability to produce large and continuously variable strain states, thus limiting the potential for designing and tuning the desired properties of ferroelectric films. Here, we observe and explore dynamic strain-induced ferroelectricity in SrTiO$_3$ by laminating freestanding oxide films onto a stretchable polymer substrate. Using a combination of scanning probe microscopy, optical second harmonic generation measurements, and atomistic modeling, we demonstrate robust room-temperature ferroelectricity in SrTiO$_3$ with 2.0% uniaxial tensile strain, corroborated by the notable features of 180° ferroelectric domains and an extrapolated transition temperature of 400 K. Our work reveals the enormous potential of employing oxide membranes to create and enhance ferroelectricity in environmentally benign lead-free oxides, which hold great promise for applications ranging from non-volatile memories and microwave electronics.

description: Based on telescopic observations of Jupiter-family comets (JFCs), there is predicted to be a paucity of objects at sub-kilometre sizes. However, several bright fireballs and some meteorites have been tenuously linked to the JFC population, showing metre-scale objects do exist in this region. In 2017, the Desert Fireball Network (DFN) observed a grazing fireball that redirected a meteoroid from an Apollo-type orbit to a JFC-like orbit. Using orbital data collected by the DFN, in this study, we have generated an artificial dataset of close terrestrial encounters that come within $1.5$ lunar distances (LD) of the Earth in the size-range of $0.01-100$kg. This range of objects is typically too small for telescopic surveys to detect, so using atmospheric impact flux data from fireball observations is currently one of the only ways to characterise these close encounters. Based on this model, we predict that within the considered size-range $2.5\times 10^{8}$ objects ($0.1\%$ of the total flux) from asteroidal orbits ($T_{J}>3$) are annually sent onto JFC-like orbits ($2

description: Eigenvalues of the Hermitian Wilson-Dirac operator are of special interest in several lattice QCD simulations, e.g., for noise reduction when evaluating all-to-all propagators. In this paper we present a Davidson-type eigensolver that utilizes the structural properties of the Hermitian Wilson-Dirac operator $Q$ to compute eigenpairs of this operator corresponding to small eigenvalues. The main idea is to exploit a synergy between the (outer) eigensolver and its (inner) iterative scheme which solves shifted linear systems. This is achieved by adapting the multigrid DD-$α$AMG algorithm to a solver for shifted systems involving the Hermitian Wilson-Dirac operator. We demonstrate that updating the coarse grid operator using eigenvector information obtained in the course of the generalized Davidson method is crucial to achieve good performance when calculating many eigenpairs, as our study of the local coherence shows. We compare our method with the commonly used software-packages PARPACK and PRIMME in numerical tests, where we are able to achieve significant improvements, with speed-ups of up to one order of magnitude and a near-linear scaling with respect to the number of eigenvalues. For illustration we compare the distribution of the small eigenvalues of $Q$ on a $64\times 32^3$ lattice with what is predicted by the Banks-Casher relation in the infinite volume limit.

description: The simulation of correlated multivariate Poisson processes with negative correlation between their components has many important applications in Finance, Insurance, Geophysics, and many other areas of applied probability. Introduced in our earlier work, the Backward Simulation (BS) approach to the simulation of correlated multivariate Poisson processes is able to capture a wide range of correlation, including extreme positive and extreme negative correlation, that is not possible with other approaches such as the forward simulation approach. Moreover, the BS approach enables simple and efficient generation of sample paths of correlated multivariate Poisson processes. In this work, we extend the BS approach to multivariate mixed Poisson processes.

description: It is a recurrent issue in astronomical data analysis that observations are unevenly sampled or incomplete maps with missing patches or intentionaly masked parts. In addition, many astrophysical emissions are non stationary processes over the sky. Hence spectral estimation using standard Fourier transforms is no longer reliable. Spectral matching ICA (SMICA) is a source separation method based on covariance matching in Fourier space which is successfully used for the separation of diffuse astrophysical emissions in Cosmic Microwave Background observations. We show here that wavelets, which are standard tools in processing non stationary data, can profitably be used to extend SMICA. Among possible applications, it is shown that gaps in data are dealt with more conveniently and with better results using this extension, wSMICA, in place of the original SMICA. The performances of these two methods are compared on simulated CMB data sets, demonstrating the advantageous use of wavelets.

description: Nos últimos anos, a avicultura brasileira tem apresentado grande crescimento na produção e a criação de perus acompanha - de certa forma - este desempenho. Como o frango de corte, grande parte da produção de carne de peru é exportada. Todavia, o frango de corte tem o consumo no mercado interno bastante consolidado, o que já não ocorre com o consumo de derivados de peru, que se apresenta bastante baixo, apesar do crescimento nos últimos cinco anos. A presente pesquisa analisou a estratégia de segmentação do mercado dos produtos à base de carne de peru, o comportamento de compra baseado nos preços desses produtos no varejo vis-à-vis os dos derivados de frango e as possíveis causas do baixo consumo per capita brasileiro. A pesquisa foi realizada em três supermercados do interior de São Paulo. Observou-se uma ampla adoção da estratégia de segmentação de derivados de peru, mas os preços ofertados ao consumidor, em sua maioria, apresentaram-se significativamente mais elevados em relação ao preço dos derivados de frango. Também foi constatado que em alguns produtos há diferença na preferência entre homens e mulheres, mas na maioria das vezes o comportamento de consumo é bastante semelhante. As principais hipóteses para as causas do baixo consumo per capita identificadas foram: preço relativamente elevado, pouca divulgação dos produtos e sazonalidade de alguns derivados. --------------------------------------------------In recent years, the Brazilian poultry production has largely grown. The turkey production somehow follows this performance. A large amount of turkey meat is exported, just like the poultry. However, the poultry meat consumption is very well consolidated in the domestic market, what does not occur with turkey derivates consumption, which is very low, despite the growth in the last five years. This research analyzed the market segmentation strategy of products made of turkey meat, as well as the purchase behavior based on prices of these products vis-à-vis prices of poultry derivates and the possible reasons that explain the low per capita consumption in Brazil. The research was conducted in three supermarkets of the State of São Paulo. A large adoption of the segmentation strategy was observed for turkey derivates, but most prices were significantly higher than poultry ones. It was also observed that there is a difference in men and women’s preferences for some products, but most of the times the consumption behavior is very similar. The main hypotheses for the low per capita consumption were: relatively high price, insufficient advertisement and seasonality of some derivates.

description: We calculate the isotope independent Li$^+$-Li potential energy curves for the electronic ground and first excited states. Scattering phase shifts and total scattering cross section for the $^7$Li$^+$-$^7$Li collision are calculated with emphasis on the ultra-low energy domain down to the $s$-wave regime. The effect of physically motivated alterations on the calculated potential energy curves is used to determine the bound of accuracy of the low-energy scattering parameters for the ion-atom system. It is found that the scattering length for the A$^2Σ_u^+$ state, $a_u$ = 1325 a$_0$, is positive and has well-constrained bounds. For the X$^2Σ_g^+$ state, the scattering length, $a_g$ = 20465 a$_0$ has a large magnitude as it is sensitive to the restrained change of the potential, due to the presence of a vibrational state in the vicinity of the dissociation limit.

description: We propose the SH model, a simplified version of the well-known SIR compartmental model of infectious diseases. With optimized parameters and initial conditions, this time-invariant two-parameter two-dimensional model is able to fit COVID-19 hospitalization data over several months with high accuracy (e.g., the root relative squared error is below 10% for Belgium over the period from 2020-03-15 to 2020-07-15). Moreover, we observed that, when the model is trained on a suitable three-week period around the first hospitalization peak for Belgium, it forecasts the subsequent two months with mean absolute percentage error (MAPE) under 4%. We repeated the experiment for each French department and found 14 of them where the MAPE was below 20%. However, when the model is trained in the increase phase, it is less successful at forecasting the subsequent evolution.

description: AIM: To describe the prevalence and spatial distribution of cattle herds infected with Ikeda and non-Ikeda types of Theileria orientalis in New Zealand between November 2012 and June 2013.METHODS: Pooled serum samples collected historically between November 2012 and June 2013 were obtained from cattle herds throughout New Zealand. Each pooled sample consisted of approximately 20 individual cattle samples from that herd, and was provided with details of the spatial location of the herd (n=722). DNA from all samples was tested using two quantitative PCR assays for the detection of T. orientalis (all types) and the Ikeda type. The proportion of herds that were positive for T. orientalis and Ikeda type, or that were positive for T. orientalis but negative for Ikeda type (non-Ikeda positive) was determined for different regions of New Zealand.RESULTS: The highest prevalence of herds infected with Ikeda type was detected in the Northland (33/35; 94%) and Auckland and the Waikato (63/191; 33%) regions. Only 2/204 (1%) herds were positive for the Ikeda type in the South Island. A high percentage of herds that were positive for non-Ikeda types was detected in the Gisborne and Hawkes Bay (23 (95%CI=13–37)%), Auckland and Waikato (22 (95%CI=16–29)%) and Bay of Plenty (24 (95%CI=10–44)%) regions.CONCLUSIONS AND CLINICAL RELEVANCE: The high prevalence of Ikeda type detected in cattle herds in the Northland, Auckland and Waikato regions represents a risk to naive cattle being introduced into these regions. There is also the potential for resident cattle herds in the Gisborne and Hawkes Bay, Auckland, Waikato and Bay of Plenty regions to experience increased infection with the Ikeda type.The overall impact experienced by regions will depend on other factors such as the number of herds present and the predominant type of farming, as well as the interplay between tick ecology, cattle immunity and movement patterns of cattle.
Characterization of the chemosensory protein gene family from the Eastern spruce budworm, Choristoneura fumiferana
Creators: name: Wanner, Kevin W.
Publisher: name: University of British Columbia
Year: 2009

description: The peripheral sensory system of insects is the first to detect chemical stimuli; it is composed of specialized sensory neurons located within hollow, hair-like sensilla. Chemosensory proteins (CSPs) and odorant binding proteins (OBPs) are small, soluble proteins that transport hydrophobic stimuli across the hydrophilic lymph that separates the sensory receptors from the external environment. Incidental results from various studies indicate that most CSPs, and some OBPs, are expressed broadly in many different tissues, raising the question 'what is their non-sensory function?' In this thesis I explored the nonsensory function of CSPs using three different scopes of investigation: 1) an in silico analysis of all known CSP sequences, 2) a characterization of the expression pattern of four CSP genes from a representative lepidopteran species, and 3) a functional characterization of an individual CSP. I identified 15 new CSP sequences; four from cDNA clones described herein and 11 from sequence databases. Several protein similarity classes, representing CSPs from six insect orders, were identified, and each was characterized by highly conserved sequence motifs, including (A) N-terminal YTTKYDN(V/I)(WD)(L/V)DEIL, (B) central DGKELKXX(I/L)PDAL, and, (C) C-terminal KYDP. Three similarity classes were identified that diverged from these conserved motifs, presumably because they are under new functional and selective pressures. A detailed analysis of the expression pattern of four CSP genes from the Eastern spruce budworm, Choristoneura fumiferana, revealed that one (characterized by the retention of the conserved motifs) was expressed in the adult stage, while two that diverged from the conserved motifs were expressed in the immature stages (larvae and pupae). Furthermore, two of the divergent CSP genes were up-regulated during a natural molt, or during an ecdysteroid agonist induced molt. The ligand binding specificity of CfumAY624538, a divergent CSP, was characterized using the fluorescent reporter 1-NPN. Some CSPs bind to medium chain-length fatty acids; this was not the case for CfumAY624538, rather, a short chain-length alcohol was the only ligand tested that displaced 1-NPN in competition. Collectively, my results indicate that divergent CSPs from the Eastern spruce budworm function in development, including larval molting.

description: Combining isotopic constraints from meteorite data with dynamical models of planet formation proves to be advantageous in identifying the best model for terrestrial planet formation. Prior studies have shown that the probability of reproducing the distinct isotopic compositions of the Earth and Mars for both classical and Grand Tack models is very low. In the framework of the Grand Tack model, for Mars to be isotopically different from the Earth, it had to form under very specific conditions. Here, we subjected a fairly new and unexplored model--the depleted disc model--to the test. It presupposes that the region in the inner protoplanetary disc from Mars' orbit and beyond is depleted in mass such that Mars is left with insufficient material to grow to a larger size. Our aim is to test the whether the distinct isotopic compositions of the Earth and Mars are a natural outcome of this model. We found that the terrestrial planets accrete material mostly locally and have feeding zones that are sufficiently distinct. The Earth and Mars, and by extension, Venus, can have distinct isotopic compositions if there is an isotopic gradient in the terrestrial planet region of the protoplanetary disc. Our results suggest that the material in the inner Solar System most likely did not undergo substantial mixing that homogenised the potential isotopic gradient, in contrast to the Grand Tack model where the feeding zones of the terrestrial planets are nearly identical due to the mixing of material by Jupiter's migration.

description: It is shown that high energy neutrino beams from very distant sources can beutilized to learn about some properties fof neutrinos such as lifetimes and mass hierarchy etc. Furthermore, even mixing elements such as U-e3 and the CPV phase can be measured in principle. Pseudo-Dirac mass differences as small as 10^-18 eV^2 can be probed as well.

description: AIM: To estimate incidence risk, cumulative mortality and case fatality rate within herds affected by bovine anaemia associated with Theileria orientalis infection (TABA), in New Zealand during the early phase of the epidemic (August 2012–September 2013).METHODS: A mixed methods approach was utilised to integrate data from various sources, including a detailed questionnaire carried out on 18 dairy farms which had experienced cases of TABA; a brief telephone survey of an additional 139 case farms; and data extracted from a Ministry for Primary Industries database for a further 42 case farms. The subsequent analysis determined incidence risk, cumulative mortality and case fatality rates for beef and dairy herds.RESULTS: Data were analysed from 196/263 (74%) known case farms at the date of closing the questionnaires. These farms contained 99,505 cattle; 2,847 animals were reported with clinical disease, and a further 590 animals were recorded as having died from TABA. The within-herd incidence risk, cumulative mortality and case fatality rate were consistent between the three data sources, did not differ between beef and dairy herds, and were estimated to be 0.97 (inter-quartile range (IQR) 0.36–2.07)%, 0.23 (IQR 0.00–0.66)% and 16.67 (IQR 0.00–33.33)%, respectively. There was substantial variability in the level of impact, with 22 farms severely affected (incidence risk >5% and cumulative mortality >5%).CONCLUSIONS: The mixed methods approach was effective in dealing with the disparate data sources. The inclusion of the majority of farms known to be affected at the time the questionnaires were performed implies that the information is likely to be representative. The collective outputs of the analyses represent the best estimate available of within-herd measures of disease frequency in the early phase of the epidemic in New Zealand. The limitations of the data imply that their primary application may be to inform the design of subsequent structured observational field studies.CLINICAL RELEVANCE: The results of this study provide information on the impact of TABA on cattle farms during the emergence and early spread of the disease, as well as for generating hypotheses on causal mechanisms and risk factors that may influence the course of disease.

description: CASE HISTORY AND CLINICAL FINDINGS: On 7 September 2012 the Ministry for Primary Industries was notified of a dairy cow with regenerative anaemia (haematocrit (HCT) 0.08 L/L) in a herd of 465 Jersey-Friesian cross cows (index case herd) in the Northland region of New Zealand. Organisms consistent with Theileria spp. were present in red blood cells on a blood smear. No other causes of anaemia were detected following examination of affected cows. Blood samples collected from 29 randomly selected cows on 26 September 2012 showed that 24 (83%) were anaemic (HCT≤0.24 L/L) and therefore fitted the case definition for bovine anaemia associated with Theileria orientalis infection.LABORATORY FINDINGS: Using a T. orientalis type-specific PCR assay that targeted the single subunit rRNA gene, all of six animals tested were positive for T. orientalis type Ikeda. Blood samples collected from clinically affected cattle in 11 subsequent outbreaks from throughout the North Island showed that T. orientalis Ikeda type was a common finding, but mixed infections with Chitose type were also identified. In addition, using a PCR assay that targeted the major piroplasm surface gene, T. orientalis type 5 was detected in one cow from the Waikato region.DIAGNOSIS: The presence of T. orientalis type Ikeda, as well as type 5, was confirmed in cattle from outbreaks of bovine anaemia in herds throughout the North Island of New Zealand.CLINICAL RELEVANCE: Two new types of T. orientalis were identified in this investigation, that were associated with a sudden rise in cases of bovine anaemia. The body of evidence showed that the Ikeda type was implicated as the cause of disease observed in this epidemic.

description: At the Karlsruhe Institue of Technology (KIT), a 3D-Ultrasound Computer Tomography (3D-USCT) medical imaging system for early breast cancer detection is currently developed. With the next generation of 3D-USCT 2.5, the current region of interest (ROI) of 10 x 10 x 10 cm³ shall be increased to 20 x 20 x 20 cm³ to allow reliable imaging results also for bigger female breasts. Therefore, the opening angle (OA) of the future transducers should be increased to approx. 60° at 3 dB while other characteristics such as bandwidth (BW) and resonance frequency should be preserved or even improved. Based on the current dice-andfill approach in transducer production, optimization is performed on piezoelectric sensor geometry and size, type and structure of matching and backing layer and interconnection technology of the several parts of the transducer.

Non-thermal leptogenesis via direct inflaton decay without SU(2)(L) triplets

description: We present a non-thermal leptogenesis scenario following standard supersymmetric hybrid inflation, in the case where light neutrinos acquire mass via the usual seesaw mechanism and inflaton decay to heavy right-handed neutrino superfields is kinematically disallowed, or the right-handed neutrinos which can be decay products of the inflaton are unable to generate sufficient baryon asymmetry via their subsequent decay. The primordial lepton asymmetry is generated through the decay of the inflaton into light particles by the interference of one-loop diagrams with exchange of different right-handed neutrinos. The mechanism requires superpotential couplings explicitly violating a U(1) R-symmetry and R-parity. We take into account the constraints from neutrino masses and mixing and the preservation of the primordial asymmetry. We consider two models, one without and one with SU(2)(R) gauge symmetry. We show that the former is viable, whereas the latter is ruled out. Although the broken R-parity need not have currently observable low-energy signatures, some R-parity-violating slepton decays may be detectable in the future colliders.

description: Estimating dynamic correlation between a pair of time series is of importance in many applications. We present new estimators for the dynamic correlation between a pair of correlated Brownian motions and separately for dynamic correlation between a pair of correlated Geometric Brownian motions. We show that, as the sample size increases, all estimators presented in this paper converge in probability to the underlying true dynamic correlation.
description: 26 pages. The old version had dynamic correlation estimators (and corresponding consistency results) for Brownian motion pairs. Note that in the new version we added estimators and consistency results for Geometric Brownian motion pairs

description: We present results for the selfenergy of the $Θ^+$ pentaquark in nuclei associated with two sources: the $KN$ decay of the $Θ^+$ and the two meson baryon decay channels of the $Θ^+$ partners in an antidecuplet of baryons. The first source is shown to produce a small potential, unable to bind the $Θ^+$ in nuclei, while the second source gives rise to a large attractive potential. At the same time we show that the width of the $Θ^+$ in nuclei is small, such that, in light and medium nuclei, many bound $Θ^+$ states would appear with a separation between levels appreciably larger than the width of the states, thus creating an ideal scenario for pentaquark spectroscopy in nuclei.
