Este trabalho pretende analisar os diferentes empregos de adjetivação no romance modernista Memórias sentimentais de João Miramar, de Oswald de Andrade, bem como a expressividade alcançada por eles dentro de seu universo textual. Procura, também, investigar a contribuição dos usos dos adjetivos para o traço de estilo mais marcante da obra: a brevidade. / This research intends to analyse different adjective uses in the modernist novel Memórias sentimentais de João Miramar, by Oswald de Andrade, as well as the expressiveness reached by them in their textual universe. It will also try to investigate the contribuition of the adjective uses to the novel more characteristic style aspect: conciseness.

De nos jours, les mémoires occupent une grande superficie en silicium dans les System-on-Chip. Très largement utilisés, les mémoires Flash non volatiles présentent encore plusieurs inconvénients. Les MRAMs permettent de répondre à toutes les problématiques liées aux Flash. Cependant, elles sont sujettes à des défauts comme tout autre type de mémoire. Très peu de travaux portent sur le test de MRAM et la recherche effectuée dans ce domaine vise principalement la première génération de mémoires magnétiques. Dans ce travail, la physique derrière la modélisation MTJ est abordée. Cette compréhension est le point de départ pour développer un modèle fiable. Le MTJ est l'élément de base pour les technologies MRAM. L'injection de défauts résistif ouvert, résistif courts-circuits et capacitives ont été réalisées dans le but d'analyser les mécanismes de défaillance spécifiques de la TAS-MRAM. Un test du type march spécifique est proposé à l'aide des résultats d'analyses d'injection de défauts et de l'association de chaque mécanisme de défaillance à un modèle de défaut fonctionnel spécifique. L'évolution du TAS-MRAM est la MRAM à base MLU qui est également développée par Crocus Technology. Finalement, un modèle MLU-MTJ sera élaboré et discuté. / Memories occupy most of the silicon area in nowadays System-on-Chips. Though widely used, non-volatile Flash memories still have several drawbacks. MRAMs have the potential to mitigate almost all Flash related issues. However, they are prone to defects as any other kind of memory. Only few studies on MRAM testing can be found in the literature, and target mainly the first generation of Magnetic Memories.In this work the physics behind MTJ modeling is discussed in this work as this understanding is the starting point in order to develop a reliable model. MTJ is the basic building block of MRAMs. Moreover, Resistive-open, resistive-bridge and capacitive of defect injection are performedin order to analyze specific failure mechanisms of TAS-MRAMs. As result of defect injection analyses and the association of each failure mechanism to a specific functional fault model, a specific march test is proposed. The evolution of TAS-MRAMs is the MLU based MRAM also developed by Crocus Technology. Finally, a MLU-MTJ model will be developed and discussed.

This way, this essay has the purpose to identify, reconstruct and record the individual memories of the elderly, whose outlined problems were the investigation of reading stories of these subjects related to their life stories. This research sought to understand how the elderly have re-meant their lives by reference to the readings done. Participants in the research were five subjects who attend to the workshop Memories and readings from Universidade Aberta ? Terceira Idade at Universidade Estadual de Feira de Santana ? Bahia. This paper analyzes issues related to family background, childhood, school, work, reader trajectory and reflects on the reinterpretation of life of the elderly based on their reading memories. The research follows a qualitative descriptive nature, with the methodological basis the story of life, using the interview as data collection tool, in order to get as much as possible from the memories of those involved. The data were analyzed through the light of cultural history, the history of reading and remembering. Therefore, it sought to support the ideas of Peter Burke (2008), Roger Chartier (2004, 2009, 2015) and Ecl?a Bosi (1994, 2013), among other scholars. By analyzing the memories of older people, it is possible to draw a profile of these readers, noting its varied modes of interaction with reading at different periods of their lives. The result of the work brings out the personal stories and reading memories of older people, revealing the importance of the act of remembering these subjects not only relive moments, events, memories from the past, but also they can redo themselves, they can re-mean themselves and then they can enjoy their aging process healthily. / Apesar do crescimento de a??es e estudos voltados para idosos nas ?ltimas d?cadas, visto o progressivo envelhecimento da popula??o brasileira, ainda h? uma fragilidade das pesquisas no que se refere ?s hist?rias de leitura de idosos, bem como sobre a import?ncia de rememorar essas hist?rias.

Mental time travel (MTT) refers to an individual’s ability to mentally travel through subjective time, autonoetically re-experiencing past events under the form of autobiographical memories (past MTT), and pre-experiencing events as future autobiographical representations (future MTT). MTT can occur voluntarily, whereby a past/future autobiographical event is subjectively experienced as an intended occurrence, or involuntarily, wherein such an event is subjectively experienced as an unintended outcome of which the individual is aware. Studies investigating MTT’s characteristics in dysphoria and depression show that dysphoric and depressed individuals produce more overgeneral and negative MTT events when compared to control groups. However, existing research has been limited to past and voluntary MTT events, with few studies investigating involuntary MTT and future MTT in dysphoria and depression. The overarching aim of the present research was to compare the phenomenological characteristics of MTT in dysphoric individuals vs. normal mood individuals (Study 1), and in clinically depressed individuals vs. never-depressed individuals (Study 2), with the purpose of furthering existing knowledge on MTT and its relation with dysphoria and Major Depressive Disorder. This aim was addressed by conducting two studies, using a 2 x (2 x 2) mixed-factorial design, with temporality (past vs. future events) and type of retrieval (voluntary vs. involuntary events) as within-subjects independent variables, and participant group as a between-subjects variable. In Study 1, Portuguese university students were categorised into a dysphoric (n=17) or a normal mood group (n=39) depending on their score on the Beck Depression Inventory (BDI-IA) – cutoff point (≥ 10). In Study 2, clinically diagnosed depressed patients (n=32) were recruited from a Portuguese hospital and matched for age and gender with never-depressed control participants (n=32) recruited from the community. The dependent variables tested were: level of spatiotemporal specificity, self-relevance, mood and physical impact, valence, and visual perspective of the MTT events produced. A diary methodology was used in both studies, with an open-ended time period that lasted for a minimum of two weeks, for participants to record their MTT events and grade them on the above mentioned variables using Likert-type ratings. Between seven and fourteen MTT events were produced for each of the four MTT conditions (past voluntary, past involuntary, future voluntary, future involuntary). Results showed that when compared to their respective control groups, depressed, but not dysphoric participants, exhibited a clear influence of mood on several of the phenomenological characteristics of MTT. In Study 1 there were no statistically significant differences in the specificity, negative valence, and mood/physical impact of the MTT events produced by dysphoric and normal mood participants. On the contrary, in Study 2, results partially supported a lower specificity and fully supported a greater negativity and mood/physical impact of MTT events in depressed individuals compared with never-depressed participants. Both studies supported the greater self-relevance of voluntary MTT events and partially supported the hypothesised effect of type of retrieval in specificity. These were the first studies to directly compare past and future, voluntary and involuntary MTT events in dysphoric and depressed individuals, addressing existing gaps in the literature. The key limitation is the relatively small sample size of both studies, however each participant was comprehensively assessed for at least two weeks, providing a rich set of reliable data. Despite limitations, this thesis provides novel pilot findings that help understand the similarities and differences between involuntary and voluntary, past and future MTT, as well as providing new information regarding the possible role of MTT in dysphoria and depression.

Os processos mnemônicos são responsáveis por manter a qualidade e estabilidade de vida de todos os seres humanos, porém pesquisas vêm mostrando ao longo do tempo, que tais processos podem apresentar erros e distorções que podem mudar o curso de nossa vida. As falsas memórias são as recordações de situações, eventos que na realidade não ocorreram exatamente como nos recordamos. Inicialmente acreditava-se que eventos vividos e que possuíssem carga emocional associada, não eram passíveis de distorção, porém já se sabe que tais premissas não são necessariamente verdadeiras. Além disso, o nível de desajustamento e instabilidade emocional interfere para um maior número de falsas memórias. A ansiedade é uma resposta adaptativa, normal e passa a ser patológica quando é desproporcional diante da situação desencadeante. Quando a ansiedade é muito intensa, tende a gerar prejuízos em todas as esferas da vida, esta ansiedade adquire um significado clínico. Dentro os transtornos de ansiedade há um diagnóstico bastante prevalente chamado de Transtorno de Ansiedade Social (TAS). O presente trabalho visou comparar participantes adultos portadores de TAS e participantes adultos sem estes sintomas, investigando o efeito da emoção na performance da memória, para um evento testemunhado. Para o desenvolvimento do trabalho foi utilizada uma sequência de onze slides, acompanhados por duas versões narrativas, sendo uma sem impacto e outra carregada emocionalmente, além de uma Escala Subjetiva de Emoção e um teste de Memória autoaplicativo. O estudo contou com 137 participantes, que foram divididos em quatro grupos: indivíduos sem transtorno de ansiedade e narrativa sem impacto emocional, indivíduos sem transtorno de ansiedade e narrativa com impacto emocional, indivíduos com transtorno de ansiedade e narrativa sem impacto emocional e indivíduos com transtorno de ansiedade e narrativa com impacto emocional. Foram realizadas análises paramétricas utilizando as análises de Variância (ANOVA). Todos os tratamentos estatísticos utilizaram um < 0,05 para o teste de hipóteses e testes post hoc com correção para Bonferroni para identificar as possíveis diferenças encontradas. Os resultados sugerem que os participantes portadores de TAS, os quais foram submetidos à versão sem impacto emocional, obtiveram índices maiores de memória verdadeira, porém apresentaram também índices superiores de falsas memórias, em função do viés atencional característico desta população, sugerindo que a ansiedade social tem uma ação significativa sobre a performance de memória. / Mnemonic processes are responsible for keeping all human beings life quality and stability. However, research has shown that such processes can present mistakes and distortions which can change the course of life. False memories are memories of situations and events that did not happen exactly as remembered. At first, it was believed that events which happened and had an associated emotional load could not be distorted; however it is now known that such premise is not necessarily true. Moreover, it is known that the level of disadjustment and emotional instability interfere for a greater number of false memories. Anxiety is a normal adaptive response but it becomes pathologic when it is not proportional to the triggering situation. When anxiety is too intense, it tends to harm all spheres of life, and it acquires a clinical meaning. Amongst the anxiety disorders, there is a prevalent diagnosis called Social Anxiety Disorder (SAD). This study aims to compare adult participants who suffer from this problem with adult participants who do not have these symptoms, investigating the effect of emotion in memory performance for an event witnessed. To develop this study, a sequence of eleven slides was used, followed by two narrative versions, one with emotional impact and the other without, besides the Subjective Scale of Emotion, a self-test for memory. The study had 137 participants, who were divided into four groups: individuals who do not suffer from the disorder and emotionally loaded narrative, individuals who do not suffer from the disorder and narrative without emotional load, individuals who suffer from the disorder and emotionally loaded narrative, individuals who suffer from the disorder and narrative without emotional load. Parametrical analysis was carried out using the Variance analysis (ANOVA). All the statistical treatments used an < 0,05 for the hypothesis test and post hoc tests with correction for Bonferroni to identify the possible differences found. The results suggest that participants with SAD who were submitted to a version without emotional impact had higher rates of real memories, according to attentional bias characteristic of this population. Besides, the participants who suffer from Social Anxiety Disorder (SAD) had higher rates of false memories who were submitted to a version without emotional impact, suggesting that emotion acted as a protection and suggesting that the social anxiety has a significant action over memory performance.

Este trabalho tem por finalidade apresentar os resultados da simetria entre o intelectual exposto por Edward Said na obra Memórias do Cárcere de Graciliano Ramos. O papel do intelectual na sociedade sempre foi alvo de questionamentos e Edward Said apresentou um modelo moderno e engajado dessa classe, que tem como missão principal representar os mais oprimidos. A importância deste trabalho se dá pela tentativa de encontrar e descrever a correspondência que existe entre as ideias de Edward Said e a conduta de Graciliano Ramos no período em que esteve preso e após a prisão também. O objetivo é traçar e entender quem é a figura que Said marca como intelectual engajado e moderno capaz de compreender os problemas sociais e, por meio de suas ideias, tentar amenizá-los, destacando as reais dificuldades que atingem as sociedades carentes. Além disso, por meio do entendimento do indivíduo exposto como intelectual por Said, apresentar os comportamentos de Graciliano Ramos em Memórias do Cárcere que os liga a esse intelectual. A hipótese é que, mesmo em situações diferentes, Edward Said e Graciliano Ramos apresentam pontos em comum e, a partir de suas ideias, conseguem dar voz aos que lhe cercam de alguma forma, mantendo seus princípios e não se deixando influenciar por fatores que não correspondem a seus ideais. / This study aims to present the results of symmetry between the intellectual exposed by Edward Said in the work Memories of prison by Graciliano Ramos. The role of the intellectual in society has always been open to question and Edward Said presented a modern model and engaged of this class, whose main mission is to represent the most oppressed. The significance of this study is by trying to find and describe the harmony that exists between the ideas of Edward Said and the conduct of Graciliano Ramos in the period when he was arrested and after arrest as well. The objective is to outline and understand who is the figure that Said mark as engaged intellectual and modern able to understand social problems and, through their ideas, trying to ease them, highlighting the real difficulties that affect the poor societies. In addition, through understanding of the exposed individual as an intellectual by Said, present the behaviors of Graciliano Ramos in Memories of prison that connects them to this intellectual. The hypothesis is that, even in different situations, Edward Said and Graciliano Ramos have points in common and, from their ideas, can give voice to those around their in any way, maintaining their principles and not letting influenced by factors that do not correspond to their ideals.

nÃo hà / Este trabalho apresenta a contemporaneidade da comunidade quilombola do povoado BoqueirÃo da Arara, no CearÃ, ressaltando prÃticas educativas e culturais que sÃo disseminadas entre seu povo, em um esforÃo de perceber a existÃncia de traÃos ancestrais africanos que resistem, desde a Ãpoca da escravidÃo. Dissertar sobre temas que tratam da negritude do povo brasileiro à transitar por universo historicamente rico e polÃmico. Por um lado, o Brasil à herdeiro da cultura da civilizaÃÃo africana, cujos traÃos estÃo evidentes nas artes, religiÃo, vocabulÃrio e culinÃria, por exemplo, mas, por outro, a sociedade deste paÃs carrega o estigma do escravismo, condenÃvel por sua violÃncia brutal. A marca racial tambÃm à responsÃvel por desigualdades sociais antigas e que perduram repercutindo em problemÃticas relacionais protagonizadas entre indivÃduos e grupos, de cunho pejorativo e preconceituoso. Os dados postos justificam a importÃncia de ampliar pesquisas sistematizadas nas comunidades negras, formadas por descendentes de antigos cativos e relevam a questÃo norteadora do estudo: no contexto atual, quais prÃticas culturais e educativas estÃo presentes no quilombo BoqueirÃo da Arara? Desta forma, tem-se como objetivo principal identificar as prÃticas educativas e compreender o construto cultural desta comunidade tradicional, destacando, em especial, as vivÃncias que carregam traÃos de ancestralidade. Para tanto, espera-se analisar as memÃrias dos remanescentes quilombolas, especialmente aqueles mais velhos, em acordo com Bosi (1994), reconstituindo histÃrias de vida, alÃm de conhecer prÃticas educativas e observar mobilidades sociais nas vivÃncias do cotidiano, compreendendo os dados sob nova perspectiva, de forma a ressignificar e atualizar concepÃÃes acerca de quilombo e quilombola cristalizadas no senso coletivo. Consoante Delory-Momberger (2006) e Wunenburguer (2007), quando defendem a ampliaÃÃo do universo imagÃtico na descriÃÃo do objeto a ser estudado, esta pesquisa serve-se de registros fotogrÃficos, em grande parte, para representar o meio ambiente e apresentar o povo da comunidade. A pesquisa qualitativa recorre ao mÃtodo HistÃria Oral e utiliza tÃcnicas de entrevistas semiestruturadas, segundo orientaÃÃo em Josso (2006) e Freitas (2002), para buscar em reminiscÃncias colhidas nas memÃrias individual e coletiva, como orientam Bergson (1999); Pollak (1992); Halbwachs (2004) e Martinho Rodrigues (2013), elementos que expÃem o seu percurso histÃrico: aspectos vivenciais, mobilidades sociais, heranÃas culturais, prÃticas educativas e saberes ancestrais. Em acordo com Gil (1999), à a revisÃo bibliogrÃfica empreendida que descortina o histÃrico de luta por visibilidade para as questÃes etnicorraciais. O movimento popular negro visto em Moura (2012) promoveu uma sÃrie de debates e reivindicaÃÃes que resultaram em conquistas cidadÃs especÃficas, como aÃÃes afirmativas e polÃticas de inclusÃo de afro-brasileiros nos espaÃos institucionais. Ao final deste estudo verificam-se saberes tradicionais que foram herdados de antepassados, como o cultivo de pomares e o trabalho artesanal com rendas, por exemplo, cuja prÃtica antiga à disseminada naturalmente entre as geraÃÃes. à possÃvel concluir que, no contexto social atual, o quilombo permanece como exemplo de espaÃo de rebeliÃo e resistÃncia, porÃm nÃo mais para fugir de cativeiro. Os remanescentes quilombolas do BoqueirÃo da Arara continuam a lutar, mas para terem assegurados seus direitos enquanto comunidade tradicional de descendentes de antigos escravos, bem como por garantia de sobrevivÃncia digna e acesso a bens sociais essenciais, como educaÃÃo, saÃde e trabalho.

Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Neste trabalho analiso quais significados a cantoria assume para cantadores e ouvintes, que sob a pressÃo de diferentes formas de comunicaÃÃo e de diversÃo dos âtempos modernosâ, direcionam suas experiÃncias e subjetividades para criaÃÃo e apreensÃo de uma arte que se realiza principalmente por meio da palavra cantada e improvisada ao som da viola. A cantoria, por meio da palavra, da voz do cantador parece possuir o poder de agir, de remexer as lembranÃas dos ouvintes, causando uma sensaÃÃo de prazer e identificaÃÃo com o que està sendo vivido e cantado. Para alcanÃar tais significados focalizo o percurso de maturaÃÃo do cantador, que ganha conformaÃÃo na certeza de possuir um âdomâ que agregado aos aspectos do ambiente social mais amplo desenvolve-se e consagra-se na aceitaÃÃo do pÃblico. PÃblico que à peÃa fundamental na criaÃÃo poÃtica da cantoria. Esses cantadores hoje circulam mais constantemente entre o universo rural e o urbano, mantendo contato com diferentes contextos, linguagens e meios de comunicaÃÃo. Implicando em mudanÃas e atualizaÃÃes no seu fazer poÃtico que, por sua vez, refletem-se na criaÃÃo de estratÃgias para a manutenÃÃo da sua relaÃÃo com o pÃblico, antes marcada predominantemente por uma relaÃÃo corpo-a-corpo e que hoje passa por mediaÃÃes como a do rÃdio, da televisÃo, do CD e DVD, o que aumenta significativamente o alcance da cantoria. As memÃrias de cantadores e ouvintes expressam deslocamentos e ressignificaÃÃes dessa arte, traduzindo um universo poÃtico que reÃne diferentes experiÃncias e tradiÃÃes. Dessa maneira, cantadores e ouvintes vÃo recriando e dando vida à cantoria por ela simbolizar sua forma de comunicaÃÃo com o mundo. Do sertÃo para a cidade, o percurso dos cantadores evoca similaridades que alcanÃam mesmo as geraÃÃes mais novas, os filhos dos sertanejos que viviam do trabalho na roÃa: a certeza de possuÃrem um dom, o convÃvio desde cedo com um universo lÃdico que encontrava nas cantorias, reisados, mamulengos, festas de padroeiras e sambas (forrÃs) seus principais representantes, os preconceitos e o combate ao estereÃtipo de vagabundo amplamente reproduzido no contexto social. Tudo o que, por fim, engendra uma disputa cultural vigente ainda hoje. / In this work, I analyze what meanings the singing assumes for singers and listeners who, under the pressure of different forms of communication and amusement in the âmodern timesâ, address their experiences and subjectivities for the creation and understanding of an art that takes place mainly through the sung and improvised words to the sound of the viola. The singing, through words, of the singerâs voice seems to have the power to act, to shuffle the memories of the listeners, causing a sensation of pleasure and identification with what is being lived and sung. To reach those meanings, I focus on the maturation route of the singer, who gains configuration by being sure that he/she has a âgiftâ, which added to aspects of the broader social atmosphere, becomes developed and acclaimed before the publicâs acceptance. The public is a fundamental piece in the poetic creation of the singing. Nowadays, those singers circulate more often between the rural and urban universes, having contact with different contexts, languages, and communication means. Thus, causing changes and updates in their poetic performance, which in turn is reflected in the creation of strategies to keep his/her relationship with the public, which used to be more of a body-to-body contact, going through other mediations, such as the radio, TV, CD, and DVD that increase the reach of singing significantly. The memories of singers and listeners express displacements and re-meanings of that art, translating a poetic universe that gathers different experiences and traditions. Thus, singers and listeners go recreating and giving life to singing; because it symbolizes his/her form of communication with the world. From the countryside to the city, the singersâ route evokes similarities that reach even the youngest generations: the children of country parents who used to make a living on plantations certainly own a âgiftâ, and have long lived with a universe of entertainment full of singings, reisados, puppets, patron saint parties and sambas (forrÃs) as the main representatives, prejudices and combats to the wandererâs stereotype thoroughly reproduced in the social context. And at last, it engenders a cultural dispute that is effective until the present time.

This study uses the pop music scene as a tool to analyse contemporary cultural history in Asia, with a focus on the cold-war and post-cold war period (1960s-1990s). The primary objective is to present how Pan-Chinese music shaped peoples’ collective memories in Asia and to investigate issues such as cultural history identification, cultural worship, colonisation, nostalgia, and how these influence each other. The secondary objective is to analyse which factors can influence peoples’ collective memories, since similar pop music and historical backgrounds in Asia can be located. A particular focus is Deng Lijun (also known as Teresa Teng) (1964-1995) who is considered the most influential popular singer able to transcend ideological barriers in Asia. Through in-depth interviews carried out in China, Taiwan, Hong Kong and Japan during 2010, audience perceptions focusing on Deng Lijun's personality, music and performances were recorded and analysed in order to create focal points regarding the collective memory of her work. The main interest of this thesis is not only her role as a singer, but also her ability to capture different cultural imaginations, to initiate processes of identification and to transcend different country’s frontiers (Taiwan, China, Hong Kong, South-East Asia and Japan), particularly since these countries champion different ideological perspectives. Her fame and commercial success had a huge cultural impact, and as a result she was the first cultural carrier to break the boundaries of the Cold-War era in Asia. Apart from examining the social, cultural and political factors that influence pop music, the industry behind it and shared audience memories, the focal point of the thesis is to draw attention to aspect of time by examining how the cold war in Asia reconstructed pop music’s cultural symbols and how these symbols were transformed through different ideological structures and facets. Using the information gathered from interviews and archives, this study explores the role of popular music in political struggles between warring ideologies and shows how those struggles both informed and were informed by the sentimental songs of a global popular music idol.

In the context of emerging non-volatile memory (NVM) where data structures can persist in-memory and are accessed through CPU loads and stores, we study how to efficiently manage data evolution. This is an extensively applied problem in both the scientific and business domains and is rapidly becoming an important component for a wider range of applications. We argue that the best way to achieve a smoother transition to the new programming model is to design a solution that is non-intrusive and generic i.e. not bound to a specific data model. We propose a novel library-level approach where the user can manage historical data directly from programming language code. This is achieved with a combination of two software layers: REWIND and VARIANT. At the bottom, lies REWIND (REcovery Write-Ahead System for In- Memory Non-Volatile Data Structures) which handles the low level specifics of NVM by dealing with write-ordering problems that arise in such context and allows recoverability of arbitrary data structures. Then, VARIANT (Versioning ARbItrary dAta structures in Non-volatile memory for Time-travel) focuses on versioning and time travel (moving between versions). We adopt a logging approach and we tightly integrate both systems for best performance by utilizing a common physical log of memory operations. With REWIND, we propose a novel recoverable log structure that permits atomic and durable appends and removals of log records. This is the keystone for building recoverable systems on top of NVM. Because latencies in recent NVM technologies such as Phase-change memory (PCM) are asymmetric, we propose novel techniques for reducing the write pressure of the recoverable log as well as mitigating the effect of synchronization control primitives such as memory fences (enhanced for NVM), i.e. barriers that enforce ordering and persistence to preceding instructions. We also propose different implementations for trading logging performance for rollback performance when this is appropriate. Finally, we revisit state-of-the-art recovery algorithms for the new context given the different latencies and synchronization control. Our results clearly indicate that current approaches for recoverability are ill-fitted for persisting data structures in the new context and it is possible to achieve low-overhead logging with customized mechanisms. Next, we focus on data evolution. We expose a simple API that allows versioning and time travel with minimal intrusiveness. We propose mechanisms for efficient and transparent cloning of Versionable data structures. This allows high concurrency since past images are returned as copies of the original data structure which remains intact. Then, we propose novel indexing techniques that significantly improve time travel performance as well as cloning with lazy schemes. We achieve a low overhead architecture by employing a mix of volatile and non-volatile data structures as well as hybrid structures that reside in both volatile and non-volatile memories. We perform an extensive evaluation of the proposed techniques and conclude that, in our context, by carefully mitigating the drawbacks of physical logging it is possible to create efficient systems for managing data evolution that are both data structure agnostic and non-intrusive.
