title: Innovative Therapeutic Strategy Targeting Neurons with Cholesterol in Huntington’s Disease: From Preclinical Studies to Clinical Trial Readiness
Creators: name: Passoni, Alice
Publisher: name: The Open University
Year: 2023

description: The current pharmacological treatment of Huntington's disease (HD) is palliative, and therapies to restore functions in patients are needed. One of the pathways affected in HD involves brain cholesterol (Chol) synthesis, which is essential for optimal synaptic transmission. Given these bases, the presented thesis proposes three different mass spectrometric strategies to support the study of cholesterol involvement in HD.

Firstly, we evaluated nose-to-brain delivery as a non-invasive strategy to deliver Chol to the adult brain. We treated wild-type (WT) and R6/2 mice with intranasal (IN) doses of liposomes loaded with Chol in single and repeated doses trials. The results indicated the effectiveness of IN Chol-loaded liposomes to deliver Chol in different brain regions. In parallel, we investigated the levels of Chol metabolites in the brain after chronic IN treatment. The results highlighted a reduction in brain Chol synthesis, mostly involving the astrocytes, with a significant reduction of desmosterol levels in R6/2 mice. Moreover, the significantly lower levels of 24S-hydroxycholesterol in R6/2 mice with higher levels of desmosterol suggested the use of administered Chol to maintain the steady state of Chol synthesis in the whole brain. The analysis of Chol metabolites in plasma and brain samples from R6/2 mice showed how the reduction of Chol synthesis related to the disease was significant only at 12 weeks of age when the disease led definitely to death. Finally, we evaluated the distribution of Chol metabolites using imaging mass spectrometry (IMS). In conclusion, the presented thesis explored the study of HD, focusing on the development of different mass spectrometric strategies to study the pharmacokinetics of the administered Chol, the alteration of Chol metabolism, and the spatial distribution of Chol metabolites in brain slices of a mouse model of the disease. The proposed methods paved the way to further investigations on the alteration of brain Chol metabolism related to HD.
A Generalized Kompaneets Formalism for Inelastic Neutrino-Nucleon Scattering in Supernova Simulations

description: Based on the Kompaneets approximation, we develop a robust methodology to calculate spectral redistribution via inelastic neutrino-nucleon scattering in the context of core-collapse supernova simulations. The resulting equations conserve lepton number to machine precision and scale linearly, not quadratically, with number of energy groups. The formalism also provides an elegant means to derive the rate of energy transfer to matter which, as it must, automatically goes to zero when the neutrino radiation field is in thermal equilibrium. Furthermore, we derive the next-higher-order in ε/mc2 correction to the neutrino Kompaneets equation. Unlike other Kompaneets schema, ours also generalizes to the case of anisotropic angular distributions, while retaining the conservative form that is a hallmark of the classical Kompaneets equation. Our formalism enables immediate incorporation into supernova codes that follow the spectral angular moments of the neutrino radiation fields.

description: We study nonlinear dynamics in models of Lorentz-violating massive gravity. The Boulware-Deser instability restricts severely the class of acceptable theories. We identify a model that is stable. It exhibits the following bizarre but interesting property: there are only two massive propagating degrees of freedom in the spectrum, and yet long-range instantaneous interactions are present in the theory. We discuss this property on a simpler example of a photon with a Lorentz-violating mass term where the issues of (a)causality are easier to understand. Depending on the values of the mass parameter these models can either be excluded, or become phenomenologically interesting. We discuss a similar example with more degrees of freedom, as well as a model without the long-range instantaneous interactions.

Reconciliation : Git₋xsan property and crown sovereignty
Creators: name: Mills, Patricia Dawn
Publisher: name: University of British Columbia
Year: 2009

description: Using the "Acts of Reconciliation", September 14, 1998, as a model, I argue that Canada, British Columbia and the Gitxsan can establish a respectful relationship acknowledging Gitxsan land tenure and their governance institutions. It is contended that the principal role the Federal Crown occupies toward the Gitxsan is protection of their rights and lax 'wiiyip from unnecessary Provincial infringements. In exchange for this protection, the Gitxsan can easily extend to Canada amnigwootxw rights (privileged rights of access for good deeds). Similarly, the relationship between the Gitxsan and the Provincial Crown could simply be based in xkyeehl (payment to the wilp). It is suggested that until 1997 Gitxsan aboriginal title and associated rights have been limited to Reserve lands or site-specific subsistence activities. Although the Gitxsan have the option of pursuing proof of their title in Court, they continue to press for a negotiated settlement that recognizes their ayooks (laws) and governance procedures. The Gitxsan believe that the essence of their relationship with the Crown in right of Canada and British Columbia is situated in the construction of protocols for consultation when either Canada or the Province desires to enact legislation to access resources or settle foreign populations within the boundaries of their lax'wiiyip. In the event that such acts limit Gitxsan access to their s. 35 rights or title, it is maintained by the Gitxsan that they have the right to compensation. As such, it is recommended that the second aspect of Gitxsan and Crown relations is situated in the development of indices for compensation. This case study uses the Proceedings at Trial for the "Delgam 'Uukw (Muldoe) et al. v. R. in right of British Columbia and Attorney General of Canada" [1991] 3 W.W.R. 97 trial heard from May 11, 1987 until June 30, 1990), the advice of various Sœm'ogits and Sœm 'oogits in the Hazelton, Kispiox, Kitwancool and Kitwanga areas, and the literature on the history of the Land Question in British Columbia.
Towards understanding the impact of global warming on malaria elimination efforts in East Africa
Creators: name: Obed M Ogega
Publisher: name: Gates Open Research
Year: 2022

description: Malaria remains to be a global health challenge of concern with approximately 241 million malaria cases and 627000 malaria deaths recorded globally in 2020 alone. The malaria cases and deaths in 2020 represent an increase of 6% and 12%, respectively, compared to 2019. Aware of the significant contribution of environmental factors in malaria transmission, this study aimed at assessing the relationship between precipitation, temperature, and clinical malaria cases in East Africa and how the relationship may change under 1.5 oC and 2.0 oC global warming levels (hereinafter GWL1.5 and GWL2.0, respectively). An analysis was done to determine the relationship between patterns in precipitation, temperature, and clinical malaria cases over the study area. Differences between precipitation and temperature value projections for periods 2008-2037 and 2023-2052 (corresponding to GWL1.5 and GWL2.0, respectively), relative to the control period (1977-2005), were computed to determine how malaria transmission may change under the two global warming levels. A predominantly positive (negative) correlation between clinical malaria cases and temperature (precipitation) was observed. Relative to the control period, no major significant changes in precipitation were shown in both warming levels. However, an increase in temperature of between 0.5 oC and 1.5 oC and 1.0 oC to 2.0 oC under GWL1.5 and GWL2.0, respectively, was recorded over the study domain. The temperature changes associated with global warming imply a likelihood of more areas in East Africa attaining the temperature thresholds that support malaria vector abundance and, potentially, malaria transmission. Hence, ongoing interventions should be intensified to sustain the gains made towards malaria elimination in East Africa, in the phase of a changing climate.
Charm mass dependence of the weak Hamiltonian in chiral perturbation theory

description: Suppose that the weak interaction Hamiltonian of four-flavour SU(4) chiral effective theory is known, for a small charm quark mass m_c. We study how the weak Hamiltonian changes as the charm quark mass increases, by integrating it out within chiral perturbation theory to obtain a three-flavour SU(3) chiral theory. We find that the ratio of the SU(3) low-energy constants which mediate Delta I=1/2 and Delta I=3/2 transitions, increases rather rapidly with m_c, as \sim m_c ln (1/m_c). The logarithmic effect originates from "penguin-type" charm loops, and could represent one of the reasons for the Delta I=1/2 rule.

description: We determine the location $λ_c$ of the mobility edge in the spectrum of the hermitian Wilson operator in pure-gauge ensembles with plaquette, Iwasaki, and DBW2 gauge actions. The results allow mapping a portion of the (quenched) Aoki phase diagram. We use Green function techniques to study the localized and extended modes. Where $λ_c>0$ we characterize the localized modes in terms of an average support length and an average localization length, the latter determined from the asymptotic decay rate of the mode density. We argue that, since the overlap operator is commonly constructed from the Wilson operator, its range is set by the value of $λ_c^{-1}$ for the Wilson operator. It follows from our numerical results that overlap simulations carried out with a cutoff of 1 GeV, even with improved gauge actions, could be afflicted by unphysical degrees of freedom as light as 250 MeV.

description: Minority game is a simple-mined econophysical model capturing the cooperative behavior among selfish players. Previous investigations, which were based on numerical simulations up to about 100 players for a certain parameter $α$ in the range $0.1 \lesssim α\lesssim 1$, suggested that memory is irrelevant to the cooperative behavior of the minority game in the so-called symmetric phase. Here using a large scale numerical simulation up to about 3000 players in the parameter range $0.01 \lesssim α\lesssim 1$, we show that the mean variance of the attendance in the minority game actually depends on the memory in the symmetric phase. We explain such dependence in the framework of crowd-anticrowd theory. Our findings conclude that one should not overlook the feedback mechanism buried under the correlation in the history time series in the study of minority game.

description: This paper is a substantially revised version of a draft paper previously circulated to some officials in Sri Lanka. The title of that paper was "Testing a New Field Channel Design: A Pilot Project of the Uda Walawe Rehabilitation Project, Sri Lanka. It was reviewed by the International Irrigation Management Institute (IIMI) - Sri Lanka Consultative" Consultative Committee at its January 1988 meeting; as the minutes of that meeting indicate, the Committee members recognized- the significance of the main findings of the draft report, and agreed that physical rehabilitation by itself could be counter productive unless supported by proper institutional changes. The paper is based on periodic observations (approximately weekly) of farmers' use of a rehabilitated pilot field channel (FC), and interviews with both farmers and field level officials, over two seasons in the Uda Walawe Scheme, Sri Lanka.

description: The evolution of disk galaxies in modified gravity is studied by using high-resolution N-body simulations. More specifically, we use the weak field limit of two modified gravity theories, i.e., nonlocal gravity (NLG) and scalar-tensor-vector gravity known as MOG, and ignore the existence of dark matter halo. On the other hand, we construct the same models in the standard dark matter model and compare their dynamics with the galactic models in modified gravity. It turns out that there are serious differences between galactic models in these different viewpoints. For example, we explicitly show that the galactic models in modified gravity, host faster bars compared to the dark matter case. On the other hand, final stellar bars are weaker in modified gravity. These facts are not new and have already been reported in our previous simulations for exponential galactic models. Therefore, our main purpose in this study is to show that the above-mentioned differences, with emphasis on the speed of the bars, are independent of the initial density profile of the adopted disk/halo. To do so, we employ different profiles for the disk and halo and show that the results remain qualitatively independent of the initial galactic models. Moreover, a more accurate method has been used to quantify the kinematic properties of the stellar bar. Our results imply that contrary to the dark matter models, bars in modified gravity are fast rotators which never leave the fast-bar region until the end of the simulation.

description: Disruption of the enzymatic activities of the transcription factor TFIIH by the small molecules Triptolide (TPL) or THZ1 could be used against cancer. Here, we used the MCF10A-ErSrc oncogenesis model to compare the effect of TFIIH inhibitors between transformed cells and their progenitors. We report that tumour cells exhibited highly increased sensitivity to TPL or THZ1 and that the combination of both had a synergic effect. TPL affects the interaction between XPB and p52, causing a reduction in the levels of XPB, p52 and p8, but not other TFIIH subunits. RNA-Seq and RNAPII-ChIP-Seq experiments showed that although the levels of many transcripts were reduced, the levels of a significant number were increased after TPL treatment, with maintained or increased RNAPII promoter occupancy. A significant number of these genes encode for factors that have been related to tumour growth and metastasis, suggesting that transformed cells might rapidly develop resistance to TPL/THZ inhibitors. Some of these genes were also overexpressed in response to THZ1, which depletion enhances the toxicity of TPL and are possible new targets against cancer.

description: We present the results of a phenomenological study of unpolarized nuclear structure functions for a wide kinematical region of x and Q^2. As a basis of our phenomenology we develop a model which takes into account a number of different nuclear effects including nuclear shadowing, Fermi motion and binding, nuclear pion excess and off-shell correction to bound nucleon structure functions. Within this approach we perform a statistical analysis of available data on the ratio of the nuclear structure functions F_2 for different nuclei in the range from the deuteron to the lead. We express the off-shell effect and the effective scattering amplitude describing nuclear shadowing in terms of few parameters which are common to all nuclei and have a clear physical interpretation. The parameters are then extracted from statistical analysis of data. As a result, we obtain an excellent overall agreement between our calculations and data in the entire kinematical region of x and Q^2. We discuss a number of applications of our model which include the calculation of the deuteron structure functions, nuclear valence and sea quark distributions and nuclear structure functions for neutrino charged-current scattering.

Survey scans (full ms) were acquired from 350-1800 m/z with data dependent monitoring of up to 8 peptide masses (precursor ions), each individually isolated in a 1.9 Da window and fragmented using HCD activation collision energy 35 and 25s dynamic exclusion. Precursor and the fragment ions were analyzed at resolutions 30,000 and 15,000, respectively, with automatic gain control (AGC) target values at 1e6 with 100 ms maximum injection time (IT) and 5e4 with 300 ms maximum IT, respectively. A lock mass of siloxane (371.1012 Da) was also used.

Tandem mass spectra were extracted by Proteome Discoverer (Version 1.4). All MS/MS samples were analyzed using Mascot (searching RefSeqComplete2012_Homo sapiens (13039 entries) assuming the digestion enzyme trypsin, a fragment ion mass tolerance of 0.050 Da and a parent ion tolerance of 15 PPM. Deamidated of asparagine and glutamine, oxidation of methionine and carbamidomethyl of cysteine were specified in Mascot as variable modifications.

description: We perform magnetic susceptibility and magnetic torque measurements on the organic $κ$-(BEDT-TTF)$_2$Hg(SCN)$_2$Br, which is recently suggested to host an exotic quantum dipole-liquid in its low-temperature insulating phase. Below the metal-insulator transition temperature, the magnetic susceptibility follows a Curie-Weiss law with a positive Curie-Weiss temperature, and a particular $M\propto \sqrt{H}$ curve is observed. The emergent ferromagnetically interacting spins amount to about 1/6 of the full spin moment of localized charges. Taking account of the possible inhomogeneous quasi-charge-order that forms a dipole-liquid, we construct a model of antiferromagnetically interacting spin chains in two adjacent charge-ordered domains, which are coupled via fluctuating charges on a Mott-dimer at the boundary. We find that the charge fluctuations can draw a weak ferromagnetic moment out of the spin singlet domains.

description: Monte Carlo simulations are used to study the magnetic relaxation of a system of single domain particles with dipolar interactions modeled by a chain of Heisenberg classical spins. We show that the so-called $T\ln(t/τ_0)$ method can be extended to interacting systems and how, from the computed master relaxation curves, the effective energy barrier distributions responsible for the relaxation can be obtained. A transition from a quasi-logarithmic to power-law behavior of the relaxation as the interaction strength is in-creased is found. By direct computation of the effective energy barriers of the system, we show that this is due to the appearance of an increasing number of small energy barriers caused by the reduction of the anisotropy energy barriers as the local dipolar fields increase.

A year in wilderness solitude

Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is part of an ongoing exploration of who I am and what it means to be alive. It is an account of one man who lives alone for a year in the wilderness and reflects on his experience. A research question - What are the physical, emotional, psychological, and spiritual effects of deep wilderness solitude? - motivates and shapes the work. I develop an innovative methodology of vigilant mindfulness combined with radically honest journal keeping and narrative writing to examine and document my own lived experience in solitude. I extend interdisciplinarity and integrate spiritual practice with academic study, and I share my work with the non-academic community. During the year in solitude I discovered unexpected answers of the heart that emerged gradually through daily living. The more deeply I trusted the process of living and accepted the world and myself as we actually are, the more joy, peace, and wonder I experienced. I believe humans often act in ecologically destructive ways because we are experientially alienated from the natural systems that sustain us. Solitude can catalyze transformations in consciousness that might lead to more sustainable behaviour. Broadly, a thesis is an invitation to reflect on something from a particular point of view. I use personal narrative to evoke an experience of wilderness solitude and to invite the reader to reflect on how our culture experiences the non-human world, on how we experience ourselves and each other, and on the relationship between direct experience, intuition, insight, and conceptual knowledge. Rather than write only about solitude, I use my edited daily journal to speak directly to the reader from solitude. Reflective essays frame the journal entries, explore various themes relevant to my lived experience, and place my research in a cultural and academic context. Two DVDs contain a movie recorded in the wilderness and a video recording of a public slideshow in which I describe my year in solitude. The recordings bring visual and auditory layers to the dissertation, and the post slideshow discussion adds an interactive element.

description: Today, most application of time-dependent density functional theory (TDDFT) use adiabatic exchange-correlation (XC) potentials that do not take into account non-local temporal effects. Incorporating such "memory" terms into XC potentials is complicated by the constraint that the derived force and torque densities must integrate to zero at every instance. This requirement can be met by deriving the potentials from an XC action that is Galilean in-variant (GI). We develop a class of simple but flexible forms for an action that respect these constraints. The basic idea is to formulate the action in terms of the Eularian-Lagrangian transformation (ELT) metric tensor, which is itself GI. The general form of the XC potentials in this class is then derived and the linear response limit is derived as well.

description: Funnel plots are a visual tool for investigating publication and other bias in meta-analysis. They are simple scatterplots of the treatment effects estimated from individual studies (horizontal axis) against a measure of study size (vertical axis). The name “funnel plot” is based on the precision in the estimation of the underlying treatment effect increasing as the sample size of component studies increases. Therefore, in the absence of bias, results from small studies will scatter widely at the bottom of the graph, with the spread narrowing among larger studies. Publication bias (the association of publication probability with the statistical significance of study results) may lead to asymmetrical funnel plots. It is, however, important to realize that publication bias is only one of a number of possible causes of funnel-plot asymmetry—funnel plots should be seen as a generic means of examining small study effects (the tendency for the smaller studies in a meta-analysis to show larger treatment effects) rather than a tool to diagnose specific types of bias. This article introduces the metafunnel command, which produces funnel plots in Stata. In accordance with published recommendations, standard error is used as the measure of study size. Treatment effects expressed as ratio measures (for example risk ratios or odds ratios) may be plotted on a log scale.

description: An improved real-time quantum Monte Carlo procedure is presented and applied to describe the electronic transfer dynamics along molecular chains. The model consists of discrete electronic sites coupled to a thermal environment which is integrated out exactly within the path integral formulation. The approach is numerically exact and its results reduce to known analytical findings (Marcus theory, golden rule) in proper limits. Special attention is paid to the role of superexchange and sequential hopping at lower temperatures in symmetric donor-bridge-acceptor systems. In contrast to previous approximate studies, superexchange turns out to play a significant role only for extremely high lying bridges where the transfer is basically frozen or for extremely low temperatures where for weaker dissipation a description in terms of rate constants is no longer feasible. For bridges with increasing length an algebraic decrease of the yield is found for short as well as for longer bridges. The approach can be extended to electronic systems with more complicated topologies including impurities and in presence of external time dependent forces.

description: The southern African population of Bearded Vultures Gypaetus barbatus has declined rapidly and it is threatened with extinction. In response to this decline and the additional threats of wind farm developments in the core of the species’ range, it has been proposed to establish a reintroduced population within their historic South African range as insurance against regional extinction. To facilitate such a reintroduction, we used Maximum Entropy Modelling based on suitable nesting habitat to identify and define five potential reintroduction sites. We then compared the suitability of these sites based on the quantification of various threats and benefits within each site. The two highest-ranking sites were located mostly in the Eastern Cape Province of South Africa. We then compared different release strategies, using a Population Viability Analysis, to determine which approach would be most likely to be successful (defined as >34 individuals after 30 years). These models suggest that establishing a captive breeding programme and releasing captive-bred young would lower failure rates to 25.5–49.8%, compared with the direct releases of wild taken fledglings, without a supporting captive breeding programme (78.3–95.7%). Our models also suggest that even in the presence of high mortality rates at the reintroduction site, such a reintroduction would still be a worthwhile project, because it reduces the probability of extinction of the southern African population by approximately 30% over a 50-year period.

description: The standard formulas for sample size and power calculation, as implemented in the command sampsi, make use of a normal approximation to the t-distribution. When the sample sizes are small, this approximation is poor, resulting in overestimating power (or underestimating sample size). One particular situation in which this is likely to be important is the field of cluster randomized trials. Although the total number of individuals in a cluster randomized trial may be large, the number of clusters will often be small. We present a simulation study from the design of a cluster randomized crossover trial that motivated this work and a command to perform more accurate sample size and power calculations based on the noncentral t-distribution.

description: The transition from individual to collective motion plays a significant role in many biological processes. While the implications of different types of particle-particle interactions for the emergence of particular modes of collective motion have been well studied, it is unclear how particular types of individual migration patterns influence collective motion. Here, motivated by swarming bacteria Myxococcus xanthus, we investigate the combined effects of the individual pattern of migration and of particle-particle interactions, on the emergence of collective migration. We analyze the effects of a feature of individual pattern migration, the persistence of motion, on the collective properties of the system that emerge from interactions among individuals; in particular, when nematic velocity alignment interaction mediates collective dynamics. We find, through computer simulations and mathematical analysis, that an initially disordered migratory state can become globally ordered by increasing either, the particle-particle alignment interaction strength or the persistence of individual migration. In contrast, we find that persistence prevents the emergence of global nematic order when both persistence and nematic alignment are comparatively high. We conclude that behavior at the population level does not only depend on interactions between individuals but also on the individuals' own intrinsic behavior.

On uniqueness of transfer rates in magnetohydrodynamic turbulence

description: In hydrodynamic and magnetohydrodynamic turbulence, expressions for the transfer rates rely on integrals over wavenumber triads $(\textbf{k,p,q})$ satisfying $\textbf{k+p+q=0}$. As an example $S_E^{uu}(\textbf{k|p,q})$ denotes the kinetic energy transfer rate to the mode $\textbf{k}$, from the two other modes in the triad, $\textbf{p}$ and $\textbf{q}$. As noted by Kraichnan (1958), in $S_E^{uu}(\textbf{k|p,q})$, what fraction of the energy transferred to the mode $\textbf{k}$ originated from $\textbf{p}$ and which from $\textbf{q}$ is unknown . Such an expression is thus incongruent with the customary description of turbulence in terms of two-scale energy exchange. Notwithstanding this issue, Dar etal. (2001) further decomposed these transfers into separate contributions from $\textbf{p}$-to-$\textbf{k}$ and $\textbf{q}$-to-$\textbf{k}$, thus introducing the concept of mode-to-mode transfers that they applied to MHD turbulence. Doing so, they had to set aside additional transfers circulating within each triad, but failed to calculate them. In the present paper we explain how to derive the complete expressions of the mode-to-mode transfers, including the circulating transfers. We do it for kinetic energy and kinetic helicity in hydrodynamic turbulence, for kinetic energy, magnetic energy and magnetic helicity in MHD turbulence. Separating the contribution of magnetic advection from magnetic stretching, the energy mode-to-mode transfer rates involving the magnetic field become uniquely defined, in striking contrast to the hydrodynamic case. The magnetic helicity mode-to-mode transfer rate is also found to be uniquely defined, contrary to kinetic helicity in hydrodynamics. We find that shell-to-shell transfer rates have the same properties as mode-to-mode transfer rates. Finally calculating the fluxes, we show how the circulating transfers cancel in accordance with conservation laws.

description: This paper explains why computing the marginal effect of a change in two variables is more complicated in nonlinear models than in linear models. The command inteff computes the correct marginal effect of a change in two interacted variables for a logit or probit model, as well as the correct standard errors. The inteff command graphs the interaction effect and saves the results to allow further investigation.

description: Os ciclones surgem na circulação geral daatmosfera e são exemplos de sumidouros deenergia térmica. Apesar dos ciclones surgirem ese desenvolverem dentro de fortes condições deinstabilidade e geralmente se apresentarem comfortes ventos, seus ciclos de vida tem o objetivode estabilizar e equilibrar a atmosfera. Eles sãoclassificados em extratropicais, subtropicais etropicais, em função da região onde atuam deseu ciclo de vida e da fonte de energia pela qualse mantêm. Como essas regiões possuemcaracterísticas muito diferentes, os processosde formação destes sistemas ciclônicos tambémsão diferentes (Anthes, 1982; Gray, 1968;).O oceano Atlântico é o segundo maior oceanoem extensão, seus efeitos de variabilidadeclimática e mesoescala oceânica sãoamplamente observados em busca decompreensão de suas implicações no tempo eclima das regiões banhadas por tal oceano.Todavia, são poucos os estudos realizados embusca dos efeitos climatológicos para a regiãodo Atlântico Sul. Pezzi et al., em 2016 ressaltam em seu trabalho a importância do entendimentoda variabilidade climática do Atlântico Sul, umavez que esta região possui ampla influência naclimatologia das regiões costeiras sul e sudestedo Brasil devido aos fenômenos atmosféricosque as atingem. Ainda, segundo a climatologiade ciclones, na região do Atlântico Sul háregiões preferenciais de formação próximo àPatagônia, Argentina, e próximo à Bacia daPrata ao longo do ano, que são mostradas nosestudos de Gan e Rao (1991) e de Guia (2011).Ao considerarmos o Brasil, cuja área de atuaçãoda Marinha do Brasil se concentra naMETAREA V – que conta com 10 milhões deKm2 -, e especialmente as regiões costeiras dosul e sudeste onde as implicações daspassagens de frentes atmosféricas tendem a sermais frequentes.Assim, o objetivo do trabalho é de é normalizaras diferentes observações históricas de ciclonesextratropicais e seu deslocamento pelo AtlânticoSul, e criar novos parâmetros de classificaçãopara estes eventos, além de um índice devariabilidade em escalas interanual e decadal.
