description: This manuscript reports on the development an expert system (DairyPert™) for application to production dairy operations in the United States. The approach combines rule and model based components in a system that permits diagnostic evaluation of a dairy's current operations. Neuron Data's NEXPERT shell is used for implementation. The shell is integrated with FoxPro database programs for data entry and delivery of system findings and results, and with an Excel spreadsheet containing the Cornell Net Carbohydrate and Protein nutrition model. Both IBM and Apple Macintosh personal computers are used as platforms for the effort. The knowledge base is structured modularly to determine constraints to greater profitability and/or production in eight key management areas. The eight key areas are nutrition (including feed ration evaluations), physical facilities, herd health, reproduction, replacement, milking practices, herd management ability, and economic constraints (including risk factors). Heuristics or "rules of thumb" used by experts in these fields are used in conjunction with the nutrition model for diagnostic purposes. For a number of the areas, input data, rules and system solution values are tracked separately for each of three facility types (freestall, corral or stanchion), for each physical enclosure or pen comprising the dairy operation, and for up to fourteen physiological animal classes within each enclosure. Thus, solution results are specified to a level of detail that permits the tendering of focused advice or management suggestions. Other key areas are concerned with problems of management and economics that relate to the overall herd situation. During system operation, results are stored at the level of detail discussed above. However, recognizing that merely listing the findings could lead to information overkill, a second set of "rules" are used by the system to prioritize and tailor the advice provided. The principle objective is to match the type of advice given to the management ability and economic capacity of the farm operator, as well as to the expected economic payoff and payback period. The resulting software package, using data for any dairy farm currently under an appropriate record keeping system, is capable of diagnosing dairy herd management problems and providing advice to the herd operator on how to correct such problems in a manner that will improve efficiency and production. The overall goal is to improve the short-and long-run management of and profitability from the dairy farm business and to prepare individual dairy operations for the adoption of new technology.

description: Spatio-temporal networks are a useful tool for examining systems such as transport networks. However, it is relatively difficult to examine continuous temporal change in the properties of network connections. Spatially correlated time series analysis often uses only distance to estimate correlations between time series, which is not necessarily applicable to a network system.Longitudinal data analysis methods that are common in epidemiology and psychology may be combined with spatio-temporal network data to capture complex temporal patterns at the level of individual observation-units, for example individual network objects. These can be used to distil complex temporal information into specific easily interpretable variables that represent a specific part, or feature, of a temporal pattern, such as the timing of maxima.This paper illustrates how these methods could be combined with geographical methods to generate meaningful and interpretable results describing spatial variation in temporal patterns of temperature in a rail network. Longitudinal methods considered were: multilevel modelling and functional data analysis.Results show differences across the longitudinal methods used that are likely down to necessary differences in model specification. The appropriate parameterisation of each method is one of several factors that will affect the utility of these methods to accurately capture temporal pattern features in a meaningful way. There is considerable scope for further investigation of the utility of these methods through simulation.

description: In this paper, we present photoemission experiments on the hole doped Haldane chain compound $Y_{2-x}Sr_xBaNiO_5$. By using the photon energy dependence of the photoemission cross section, we identified the symmetry of the first ionisation states (d type). Hole doping in this system leads to a significant increase in the spectral weight at the top of the valence band without any change in the vicinity of the Fermi energy. This behavior, not observed in other charge transfer oxides at low doping level, could result from the inhomogeneous character of the doped system and from a Ni 3d-O 2p hybridization enhancement due to the shortening of the relevant Ni-O distance in the localized hole-doped regions.

description: Johannes Kepler described the Copernican universe as consisting of a central, small, brilliant sun with its planetary system, all surrounded by giant stars. These stars were far larger than, and much dimmer than, the sun -- his De Stella Nova shows that every visible star must exceed the size of the Earth's orbit, and the most prominent stars may exceed the size of the entire planetary system. His other writings, including his response to Ingoli, his Dissertatio cum Nuncio Sidereo, and his Epitome Astronomiae Copernicanae, also reflect this Copernican universe. To Kepler, such a universe was an illustration of divine power -- and solid evidence against the stars being suns, against the universe of Giordano Bruno. Kepler's starry universe was in fact the Copernican universe supported by observations of the stars, which showed them to have measureable apparent sizes. Not until the later seventeenth century were those apparent sizes shown to be spurious, allowing for a universe in which the stars were suns.

description: A problem persists in measuring the welfare effects of simultaneous price and income changes because the Hicksian compensating variation (CV) and equivalent variation (EV), while unique, are based on unobservable (Hicksian) demand functions, and observable (Marshallian) demand functions do not necessarily yield a unique Marshallian consumer's surplus (CS). This paper proposes a solution by a Taylor series expansion of the expenditure function to approximate CV and EV by way of the Slutsky equation to transform Hicksian price effects into Marshallian price and income effects. The procedure is contrasted with McKenzie's "money metric" (MM) measure derived from a Taylor series expansion of the indirect utility function. MM requires a crucial assumption about the marginal utility of income to monetize changes in utility levels. No such assumption is required by the proposed procedure because the expenditure function is measured in money units. The expenditure approach can be used to approximate EV and CV while the MM is an approximation to EV. The EV and CV approximations are shown to be very accurate in numerical examples of two prices and income changing simultaneously, and are generally more accurate than MM.

description: The interaction of non-monochromatic radiation with two types of arrays comprising both plasmonic and dielectric nanoparticles has been studied in detail. We have shown that dielectric nanoparticle arrays provide a complete selective reflection of an incident plane wave within a narrow spectral line of collective lattice resonance with a Q-factor of $10^3$ or larger, whereas plasmonic refractory TiN and chemically stable Au nanoparticle arrays demonstrated high-Q resonances with moderate reflectivity. The spectral position of these resonance lines is determined by the lattice period, as well as the size, shape and material composition of the particles. Moreover, the arrays, with fixed dimensional parameters make it possible to fine-tune the position of a selected resonant spectral line by tilting the array relative to the direction of the incident radiation. These effects provide possibilities for engineering of novel selective tunable optical high-Q filters in a wide range of wavelengths: from visible to middle IR. Several highly refractive dielectric nanoparticle materials with low absorption are proposed for various spectral ranges, such as LiNbO$_3$, TiO$_2$, GaAs, Si, and Ge.

Put$$X:=\bigcup_{j=1}^N A_1\times...\times A_{j-1}\times D_j\times A_{j+1}\times...\times A_N\subset\Bbb C^{k_1+...+k_N}.$$Let $U$ be an open connected neighborhood of $X$ and let $M\varsubsetneq U$ be an analytic subset. Then there exists an analytic subset $\hat M$ of the `envelope of holomorphy' $\hat X$ of $X$ with $\hat M\cap X\subset M$ such that for every function $f$ separately holomorphic on $X\setminus M$ there exists an $\hat f$ holomorphic on $\hat X\setminus\hat M$ with $\hat f|_{X\setminus M}=f$. The result generalizes special cases which were studied in \cite{Ökt 1998}, \cite{Ökt 1999}, \cite{Sic 2000}, and \cite{Jar-Pfl 2001}.

description: Timely monitoring and modeling of landuse change is vital to manage land resources effectively and to rectify defective land use policies, especially in rapidly urbanizing areas. Our research is applied to an annual land use dataset in order to simulate urban expansion in a fast developing area, through a hybrid model coupling Artificial Neural Networks (ANNs), cellular automata (CA), and Markov Chain (MC). The ANNs were optimized to create the urban suitability index (USI) map that was then integrated with CA-MC to spatially allocate urban expansion cells. Two ANNs, multiple-layer perceptron (MLP) and long short-term memory network (LSTM), were implemented comparatively. Since LSTM is able to take into account more temporal information, it outperformed MLP in modelling urban expansion process over a short temporal interval. The results, validated using kappa and fuzzy kappa simulation, indicate that the integration of ANNs with CA-MC can capture the possible nonlinear relationship between urban expansion and its drivers, hence it can accurately simulate and predict urban expansion in the study area.

description: We study thermal transport in one dimensional spin systems both in the presence and absence of impurities. In the absence of disorder, all these spin systems display a temperature dependent Drude peak in the thermal conductivity. In gapless systems, the low temperature Drude weight is proportional to temperature and to the central charge which characterizes the conformal field theory that describes the system at low energies. On the other hand, the low temperature Drude weight of spin gap systems shows an activated behavior modulated by a power law. For temperatures higher than the spin gap, one recovers the linear T behavior akin to gapless systems. For temperatures larger than the exchange coupling, the Drude weight decays as 1/T^2. We argue that this behavior is a generic feature of quasi one dimensional spin gap systems with a relativistic-like low energy dispersion. We also consider the effect of a magnetic field on the Drude weight with emphasis on the commensurate-incommensurate transition induced by it. We then study the effect of nonmagnetic impurities on the thermal conductivity of the dimerized XY chain and the spin-1/2 two leg ladder. Impurities destroy the Drude peak and the thermal conductivity exhibits a purely activated behavior at low temperature, with an activation gap renormalized by disorder. The relevance of these results for experiments is briefly discussed.

description: A novel search for heavy vector resonances in the $H\rightarrow b\bar{b}$ and $Z\rightarrow b\bar{b}$ final states in association with a leptonically decaying $V$ ($Z$ or $W$) and $W$-only respectively, is proposed. It is argued that excesses with respect to the Standard Model prediction should be observed in all final states (0, 1 or 2 leptons), with the 1-lepton final state being the strongest. Since the relative strengths of these excesses depend on branching ratios and efficiencies, this is a clear signal for the presence of heavy resonances or their low mass tails. A general vector-triplet model is used to explore the discovery potential as a function of the resonance mass and width. Recent Higgs to $b\bar{b}$ observation data reported by the experiments ATLAS and CMS are used to test the model. Current limits are extended to resonance widths over mass as large as 9%.

description: The effect of proximity to a Mott insulating phase on the charge transport properties of a superconductor is determined. An action describing the low energy physics is formulated and different scenarios for the approach to the Mott phase are distinguished by different variation with doping of the parameters in the action. A crucial issue is found to be the doping dependence of the quasiparticle charge which is defined here and which controls the temperature and field dependence of the electromagnetic response functions. Presently available data on high-T$_{c}$ superconductors are analysed. The data, while neither complete nor entirely consistent, suggest that neither the quasiparticle velocity nor the quasiparticle charge vanish as the Mott phase is approached, in contradiction to the predictions of several widely studied theories of lightly doped Mott insulators. Implications of the results for the structure of vortices in high-T$_{c}$ superconductors are determined. The numerical coefficients in the field-dependent specific heat are given for square and triangular vortex lattices.

description: Consumer search and product variety have been studied extensively in both the marketing and economics literature for the past 50 years. The idea that consumer have heterogenous search costs which lead some consumers to become more informed about product information than others has been used to explain a number of phenomenon. However, past theoretical models assume that consumers make a single purchase at each shopping occasion and their budget and search costs are all absorbed by that single product purchase. Our paper extends the current literature by allowing for the observation that consumers may make multiple purchases as well as single product purchases. We find that their is an optimal number of products for which the consumer would chose to search, which is critically dependent on the degree to which the consumer becomes satiated by the products, and their preference for variety. What's more, we develop this in a framework amenable to empirical work which directly allows for the estimation of the consumer's satiation and preference for variety parameters.

description: Cellular Automata (CA) have formed an important part of the geocomputational and spatial analysis toolbox for three decades. Some of the most important components of CA are the transition rules to determine the changes in cell states across iterations. These are applied at the micro-sale, but lead to emergent patterns at the macro-scale. An important consideration for transition rules is the spatial extent over which they will be valid. One does not expect the same rules to apply equally across an entire region, yet most CA implementations only support one set of transition rules that are applied everywhere. In this paper, a vector CA model with spatially partitioned transition rules is proposed to identify the expansion of urban residential areas across heterogeneous study area. Initial experiments using two sub-regions of Ipswich, Queensland, Australia, indicate that the spatially partitioned approach can improve the accuracy of vector CA.

Curriculum in occupational therapy education programs is influenced by standards that include broad statements about the inclusion of the core concept of occupation; however, these can be interpreted and implemented in a variety of ways. Research has identified the crucial role individual educators have in teaching about occupation. However, there is a lack of research into how individual teachers educate. This study explored how Australian entry-level occupation-centred occupational therapy educators develop and enact their teaching. More specifically, it explored what factors from an educator's history influence their approach to teaching about occupation, what methods and approaches they use in the their university-based teaching, and why they use those methods.

Μέσω του προγράμματος ReflexW δημιουργήθηκαν συνθετικές τομές γεωραντάρ για απλό μοντέλο αποτελούμενο από ψαμμιτικούς λίθους και συνδετικό υλικό. Αρχικά προσδιορίστηκαν η γεωμετρία των λίθων και οι φυσικές ιδιότητες των υλικών σύμφωνα με την βιβλιογραφία. Στην συνέχεια έγινε η ανάλυση των συνθετικών δεδομένων γεωραντάρ. Σε δεύτερο στάδιο, διενεργήθηκε γεωφυσική διασκόπηση στους τοίχους των Νεωρίων με στόχο την απεικόνιση της λιθοδομής χρησιμοποιώντας τη μέθοδο του γεωραντάρ σε συνδυασμό με την ηλεκτρική τομογραφία.
Από την γεωφυσική διασκόπηση σε επιλεγμένες θέσεις στους τοίχους των Νεωρίων προέκυψε ότι το πάχος της λιθοδομής δεν ξεπερνά τα 0.4m. Από την ταχύτητα διάδοσης των ηλεκτρομαγνητικών κυμάτων εκτιμήθηκε η υγρασία στους τοίχους η οποία κυμαίνεται από 20-32% κ.ο. Στις γεωηλεκτρικές τομές, η ειδική ηλεκτρική αντίσταση της λιθοδομής εμφανίζει συνήθως υψηλότερες τιμές σε σχέση με την αντίστοιχη στους αργόλιθους των τοίχων.

description: Maximum entropy models are considered by many to be one of the most promising avenues of language modeling research. Unfortunately, long training times make maximum entropy research difficult. We present a novel speedup technique: we change the form of the model to use classes. Our speedup works by creating two maximum entropy models, the first of which predicts the class of each word, and the second of which predicts the word itself. This factoring of the model leads to fewer non-zero indicator functions, and faster normalization, achieving speedups of up to a factor of 35 over one of the best previous techniques. It also results in typically slightly lower perplexities. The same trick can be used to speed training of other machine learning techniques, e.g. neural networks, applied to any problem with a large number of outputs, such as language modeling.

description: We employ a game engine – Unity – to create a rockfall simulation that integrates high resolution slope data from LiDAR scanning and photogrammetry, simulates hundreds of rocks moving on a slope, and provides outputs relevant to geological engineering decision support. This approach, in contrast to existing rockfall simulation tools that are specific to limited slope types, is general, extensible, and robust. The use of a game engine as a simulator for surface geological processes represents a novel approach to geocomputationthat leverages the physics simulation capability of games and the powerful terrain representation and visualization capabilities of 3D game engines.

description: This paper provides an overview of first- and second- generation biofuels. First-generation biofuels are ethanol-derived from food crops such as grains and sugar cane, and biodiesel, which use feedstocks of vegetable oils and animal fats. The technologies for manufacturing first-generation biofuels are generally mature and are commercially available. It is also noted that biogas is gaining favour in countries such as Sweden, where it currently accounts for about half the vehicle gas use. The focus of the paper then shifts to consider alternative processing paths under development, using non-food crops and agricultural and forestry residues. The two major pathways are: Biochemical — conversion of cellulose and hemicellulose to sugars and their fermentation to alcohol fuels and; Thermochemical — gasification of biomass to a syngas rich in carbon monoxide and hydrogen, and synthesis to fuels. The paper also considers the production and use of pyrolysis bio-oil as a fuel and as an intermediate product for conversion to transportation fuels. The land areas required for the production of various biofuels are considered, together with their greenhouse gas reduction potentials. Work related to the global potential of biofuels for meeting future energy needs is briefly discussed.

description: This paper studies the function field of an algebraic curve over an arbitrary perfect field by using the Weil reciprocity law and topologies on the adele ring. A topological subgroup of the idele class group is introduced and it is shown how it encodes arithmetic properties of the base field and of the Picard group of the curve. These results are applied to study extensions of the function field.

description: החברה הישראלית מתאפיינת בכמה שסעים עמוקים, שאחד מהם הוא השסע בין המגזר החילוני למגזר הדתי. במחקר זה נבדק אם בוגרי שירות צבאי ולאומי, שקשרו במהלך השירות קשרי חברות עם אנשים שונים מהם במידת הדתיות שלהם, יהיו מוכנים לחזור על חוויה זו בעת לימודיהם האקדמיים. המחקר נערך בשני שלבים: בשלב ראשון, המשתתפים בקבוצת מדגם מילאו שאלונים, ובשלב השני נאספו משתתפים אחרים, שהשתתפו בראיונות. המחקר מצא כי בוגרי שירות צבאי ולאומי אינם נוטים לשמר חברויות מזמן השירות. שלוש עד חמש שנים אחרי שירותם, בוגרי שירות אינם שומרים בדרך כלל על קשר קרוב עם חברים ששירתו עמם. עם זאת, בוגרי שירות נוטים לשחזר את חברויות השירות שלהם גם בעת לימודים; כלומר, מי שהיו להם חברים שונים מהם במידת דתיותם בעת השירות, נוטים לשוב ולהתחבר עם השונים מהם גם בתקופת הלימודים. חילונים שהיו להם חברים דתיים בעת השירות מתחברים עם דתיים גם במשך לימודיהם האקדמיים, ולהפך. עם זאת, ניסיון השירות מלמד אותם גם את מגבלותיה של חברות זו, והם מגיעים למערכות יחסים אלו באופן מפוכח. ברור להם יותר לאילו ויתורים הם מוכנים ולאילו לא. אך הדבר אינו מונע מהם לשוב ולהתחבר עם השונים מהם, וליצור חברויות אמיצות וטובות למרות ההבדל באורח חייהם. .

description: A gauged $U(1)_X$ extension of the Standard Model is a simple and consistent framework to naturally incorporate three right-handed neutrinos (RHNs) for generating the observed light neutrino masses and mixing by the type-I seesaw mechanism. We examine the collider testability of the $U(1)_X$ model, both in its minimal form with the conventional charges, as well as with an alternative charge assignment, via the resonant production of the $U(1)_X$ gauge boson ($Z^\prime$) and its subsequent decay into a pair of RHNs. We first derive an updated upper limit on the new gauge coupling $g_X$ as a function of the $Z'$-boson mass from the latest LHC dilepton searches. Then we identify the maximum possible cross section for the RHN pair-production under these constraints. Finally, we investigate the possibility of having one of the RHNs long-lived, even for a TeV-scale mass. Employing the general parametrization for the light neutrino mass matrix to reproduce the observed neutrino oscillation data, we perform a parameter scan and find a simple formula for the maximum RHN lifetime as a function of the lightest neutrino mass eigenvalue ($m_{\rm lightest}$). We find that for $m_{\rm lightest}\lesssim 10^{-5}$ eV, one of the RHNs in the minimal $U(1)_X$ scenario can be long-lived with a displaced-vertex signature which can be searched for at the LHC and/or with a dedicated long-lived particle detector, such as MATHUSLA. In other words, once a long-lived RHN is observed, we can set an upper bound on the lightest neutrino mass in this model.

description: Using the Algebraic Bethe Ansatz we consider the correlation functions of the integrable higher spin chains. We apply a method recently developed for the spin $\frac 12$ Heisenberg chain, based on the solution of the quantum inverse problem. We construct a representation for the correlation functions on a finite chain for arbitrary spin. Then we show how the string solutions of the Bethe equations can be considered in the framework of this approach in the thermodynamic limit. Finally, a multiple integral representation for the spin 1 zero temperature correlation functions is obtained in the thermodynamic limit.

description: Increasing the efficiency of materials design and discovery remains a significant challenge, especially given the prohibitively large size of chemical compound space. The use of a chemically transferable coarse-grained model enables different molecular fragments to map to the same bead type, while also reducing computational expense. These properties further increase screening efficiency, as many compounds are screened through the use of a single coarse-grained simulation, effectively reducing the size of chemical compound space. Here, we propose new criteria for the rational design of coarse-grained models that allows for the optimization of their chemical transferability and evaluate the Martini model within this framework. We further investigate the scope of this chemical transferability by parameterizing three Martini-like models, in which the number of bead types ranges from five to sixteen for the different force fields. We then implement a Bayesian approach to determining which chemical groups are more likely to be present on fragments corresponding to specific bead types for each model. We demonstrate that a level of performance and accuracy comparable to Martini can be obtained by using a force field with fewer bead types. However, the advantage of including more bead types is a reduction of uncertainty with respect to back-mapping these bead types to specific chemistries. Just as reducing the size of the coarse-grained particles leads to a finer mapping of conformational space, increasing the number of bead types yields a finer mapping of chemical compound space. Finally, we note that, due to the relatively large size of the chemical fragments that map to a single martini bead, a clear resolution limit arises when using the water/octanol partition free energy as the only descriptor when coarse-graining chemical compound space.

description: Controlled drug delivery systems are vital for successfully treating a wide range of diseases. Mathematical models are essential in developing new polymeric and transdermal delivery systems. In this dissertation, mathematical models have been built to investigate the effects of multiple transport mechanisms on drug delivery. A compartmental model of drug release from polymeric devices is used to simulate diffusion and surface erosion simultaneously. The effects of particle polydispersity, instantaneous binding and hydrophilic shells are investigated. The model highlights the relative impact of each transport mechanism on delivery, showing that binding and surface erosion can be used in a diffusion model to fit early burst release and later prolonged release phases simultaneously. A similar model is used to simulate transdermal delivery, incorporating diffusion, epidermal turnover and slow equilibration processes. It is shown that the presence of slow binding events in the stratum corneum can enhance the effect of epidermal turnover on in vivo delivery. Fitting to experimental data for theophylline found in the literature shows that epidermal turnover may affect smaller, more hydrophilic drugs than previously believed due to slow binding. It is shown that this could be an important contribution to the discrepancy between in vitro and in vivo data often observed. A two-dimensional finite element model is developed in Python to investigate the effect of lipid layer structure and cornified envelope permeability on permeation pathways. It is shown that a realistic depiction of lipid phase anisotropy leads to a higher contribution of intercellular transport than predicted by previous models of lipid anisotropy. Limited cornified envelope permeability is investigated as an alternative method for simulating the effects of anisotropic diffusion.
Proton Induced Pion Production from Light Nuclei in the Region of the a ∆₁₂₃₂ Resonance

Publisher: name: TRIUMF

description: Proton induced pion production has been investigated in a series of experiments using the Medium Resolution Spectrometer at TRIUMF. Data were obtained for the ⁷Li(p̄, π⁺)⁸Li*, ¹²C(p, π⁺)¹³C*, ¹³C(p, π⁻)¹⁴O*, ¹³C(p, π⁺)¹⁴C*, and ¹⁶O(p̄, π⁺)¹⁷O* reactions at Tp = 250 , 354 and 489 MeV, and are compared with previously published results taken at other energies above and below the ∆₁₂₃₂ resonance region. Because the signatures of the ∆₁₂₃₂ resonance should be the least ambiguous in this energy range, theoretical calculations which include ∆₁₂₃₂ degrees of freedom should be able to describe these results, if they are to have any hope at describing the experimental situation at all. At fixed four-momentum transfers squared of t > 0.45 GeV²/c², the (p, π⁺) differential cross sections exhibit a maximum near the invariant mass of the ∆₁₂₃₂. This energy dependence is similar to that shown by the pp → dπ⁺ reaction at equivalent center of mass energy and four-momentum transfer squared, and thus it provides strong evidence of a NN →NNπ⁺ process in the (p, π⁺) reaction mechanism. Unlike the (p, π⁺) reactions, the differential cross sections of the (p, π⁻) reactions decrease with increasing energy through this region. This difference is consistent with an interpretation of the (p, π⁻) reaction mechanism as a NN → NN π⁻ process in which non-resonant amplitudes are dominant in this region. Analyzing power angular distributions for many states of the ⁷Li(p̄, π⁺)⁸Li* and ¹⁶O(p̄, π⁺)¹⁷O* reactions exhibit broad similarities with those of the p̄p → dπ⁺ reaction. Interpretation of this trend is complicated by other analyzing power angular distributions which have entirely different shapes. Data were also obtained for the inclusive pion production reactions to the continuum. Double differential cross sections display an energy dependence similar to that of the pp → dπ⁺ reaction, and analyzing power angular distributions are similar to those of the p̄p → dπ⁺ reaction. This is consistent with earlier interpretations of a quasi-free NN → NNπ⁺ process occurring within the nuclear environment. Theoretical calculations have been performed for two of the exclusive reactions studied in this work. A resonant two nucleon model, and a relativistic stripping model using a ∆-hole potential, both do a better job of describing the differential cross section data at the ∆₁₂₃₂ invariant mass than at lower energies. Both calculations can only be said to qualitatively describe the broad features of the analyzing power data. Thus, the results presented in this thesis indicate that there are some effects of the ∆₁₂₃₂ resonance in the (p, π⁺) reaction, but that these effects are less clear in the (p, π⁻) reaction.

description: In this paper we proceed into the next step of formalization of a consistent dual theory for mass dimension one spinors. This task is developed approaching the two different and complementary aspects of such duals, clarifying its algebraic structure and the so called $τ-$deformation. The former regards the mathematical equivalence of the recent proposed Lorentz preserving dual with the duals of algebraic spinors, from Clifford algebras, showing the consistency and generality of the new dual. Moreover, by revealing its automorphism structure, the hole of the $τ-$deformation and contrasting the action group orbits with other Lorentz breaking scenarios, we argue that the new mass dimension one dual theory is placed over solid and consistent basis.
