Abstract:
When new predators invade a habitat, either through range extensions or introductions, prey may be at a high risk because they do not recognize the predators as dangerous. The nine-banded armadillo (Dasypus novemcinctus) has recently expanded its range in North America. Armadillos forage by searching soil and leaf litter, consuming invertebrates and small vertebrates, including salamanders. We tested whether Ozark zigzag salamanders (Plethodon angusticlavius) from a population coexisting with armadillos for about 30 years exhibit antipredator behavior in the presence of armadillo chemical cues and whether they can discriminate between stimuli from armadillos and a nonpredatory sympatric mammal (white-tailed deer,Odocoileus virginianus). Salamanders appeared to recognize substrate cues from armadillos as a threat because they increased escape behaviors and oxygen consumption. When exposed to airborne cues from armadillos, salamanders also exhibited an antipredator response by spending more time in an inconspicuous posture. Additionally, individually consistent behaviors across treatments for some response variables suggest the potential for a behavioral syndrome in this species.

Abstract:
The nine-banded armadillo (Dasypus novemcinctus) has become a recent addition to the local fauna of Illinois as a response to habitat alteration and climate change. This range expansion has resulted in the presence of armadillos in areas not predicted by earlier models. Although these models have been revised, armadillos continue to move north and have reached areas of heavy agricultural use. We identified conditions that favor the presence of armadillos and potential corridors for dispersal. Identifying the distribution of the armadillo in Illinois is a vital step in anticipating their arrival in areas containing potentially sensitive wildlife populations and habitats. Armadillo locations (n = 37) collected during 2016–2020 were used to develop a map of the potential distribution of armadillos in southern Illinois. Environmental data layers included in the model were land cover type, distance to water, distance to forest edge, human modification, and climactic variables. Land cover type was the most important contributing variable to the model. Our results are consistent with the tenet that armadillo activity and dispersal corridors are centered around riparian areas, and that forested cover may provide corridors an agricultural mosaic.

Abstract:
The geographic range of the nine-banded armadillo (Dasypus novemcinctus) has rapidly been expanding within the United States for the last 150 years. One of the factors contributing to this astounding range expansion is the species’ ability to survive in and colonize human-dominated areas. Despite the fact that armadillos live alongside humans in numerous towns and cities across the Southeastern, Southcentral, and now Midwestern United States, we know relatively little about the behavior and ecology of armadillos in human-developed areas. Here, we used motion-triggered game cameras in over 115 residential yards in the rapidly developing Northwest corner of Arkansas to survey armadillos in a largely suburban environment. Our objectives were to explore trends in armadillo occupancy and daily activity patterns in a suburban setting. We documented armadillos in approximately 84% of the yards surveyed indicating that the species was widespread throughout the environment. We found that the species was more likely to occupy yards surrounded by a high proportion of forest cover. We found no relationship between armadillo occupancy and other land cover or development covariates. Only 2% of nearly 2000 armadillo detections occurred during the day indicating that the species is almost exclusively nocturnal during the summer months when living near humans in the suburban environment, which we suggest is likely an adaptation to avoid contact with humans and their dogs. As the armadillo continues to expand its geographic range to areas where it has not previously occurred, understanding how human development supports and facilitates the spread of this species can elucidate areas where conflict between humans and armadillos might occur allowing for preemptive management or education to mitigate conflict.

Abstract:
In the nineteenth century, an animal from the Americas known as the armadillo offered an extraordinary subject for zoologists engaged in the study of the outer covering of four-limbed vertebrates and its components. The armadillo, a cuirassed living mammal, had excited the curiosity of European naturalists since the early sixteenth century, and their shells had thus become a common sight in collections. The armadillo’s carapace provided a structure that could be scrutinized in order to understand animal materials, one that afforded the use of microscopes and chemistry in the emerging life sciences that tried to understand the relationship between form and function and the chemical composition of animated matter. The carapace of the armadillo moved from the culture of curiosity in which it was first collected into the new field of animal chemistry, a key move that is crucial for historians to understand the emergence of the study of animal materials. Armadillos accompanied the expansion of chemistry, microscopy, and physics as they were used to study the materials that constituted the mammals’ dermal coverings. This paper mines nineteenth-century publications for episodes connected to the long story of the study of this shell’s anatomical and chemical contrivances, and the crucial role it played both in the emergence of new scientific knowledge and in the discovery of new bio-inspired materials still derived from this animal today. This paper is part of a special issue entitled “Making Animal Materials in Time,” edited by Laurence Douny and Lisa Onaga.

AbstractSuccessful conservation actions require strategies that combine research, policy formulation and enforcement, practical interventions and education. Here we review the Armadillo Conservation Programme, which was initiated in 2012 as a pioneering multidisciplinary programme for the conservation and management of five armadillo species in the Orinoco Llanos of Colombia. It is led by a multi-institutional alliance that ensures active participation of stakeholders during all stages of the programme. Six main threats affecting armadillo populations in the Llanos were identified, and these were addressed in the first joint action plan of two Colombian environmental authorities. Scientific research facilitated an increase in the knowledge available about the armadillos of the Llanos, and the recategorization of the northern long-nosed armadilloDasypus sabanicolaon the IUCN Red List. Threat evaluation and mitigation included the assessment of illegal bushmeat trade and consumption in local restaurants and the establishment of a certification label for restaurants that do not sell wild meat. Multiple strategies were used to raise awareness about armadillos and position them as flagship species for the Llanos, including education programmes in schools, travelling exhibitions, talks at universities, and the publication of several books. The local communities were actively involved through a network of private reserves committed to the conservation of armadillos, in which armadillos are protected from poaching and monitored by farmers. Breeding and rehabilitation facilities were established that can host confiscated armadillos and raise awareness among the local communities. This case study shows that conservation programmes targeted at inconspicuous and poorly known species can be successful.

Abstract:
Armadillos of the species Dasypus novemcinctus have been used as an experimental model of leprosy. Besides non-human primates, they are the only species naturally infected with Mycobacterium leprae and when experimentally inoculated, reproduce the lepromatous form of the disease producing large quantities of bacilli. This species has been maintained in captivity by numerous researchers and specific housing and feeding requirements have been developed to guarantee their survival during long experimental periods. In the "Lauro de Souza Lima" Institute, armadillos receive dog food, ground beef, boiled eggs and vitamin C. However, despite the balanced diet, anemia has been observed in some captive animals, especially in armadillos inoculated with M. leprae in advanced stages of infection. Thus, the objective of the present study was to evaluate the effect of iron sulfate supplementation in the feed provided for armadillos, both inoculated and non-inoculated with M. leprae, by means of the evaluation of their hematological profile. Fourteen armadillos received 10 mg/animal of iron sulfate (Hematofer®) diluted in sterile water mixed with their daily feed for 50 days. Hemograms and serum iron dosages for each armadillo were performed before and after supplementation. The hematocrit values increased significantly after iron supplementation, both in armadillos inoculated and non-inoculated with M. leprae. It is possible that the amount of iron in the feed is insufficient for the formation of hemoglobin, leading to microcytic anemia. Dietary supplementation with iron sulfate reversed this state, showing the importance of understanding the metabolism of exotic species for their maintenance in captivity, and thus ensuring their well-being.

We recorded the first event of six-banded armadillo carrying offspring in their mouth in Brazil on October 2022, at 06:36, Goiás. We searched for additional records in Web of Science, Scopus, Google Scholar, and social media platforms (Instagram, TikTok, YouTube). We found two articles and seven Brazilian videos depicting armadillos carrying offspring in their mouths. While this is a common reproductive behavior, it might also relate to shelter disturbance. Despite incomplete social media records regarding date, time, location, and collector, they underscore the significance of citizen science in showcasing Brazilian biodiversity and contributing to our understanding of armadillos' natural history.

Abstract:
Background The systematics of long-nosed armadillos (genus Dasypus) has been mainly based on a handful of external morphological characters and classical measurements. Here, we studied the pattern of morphological variation in the skull of long-nosed armadillos species, with a focus on the systematics of the widely distributed nine-banded armadillo (Dasypus novemcinctus). Methods We present the first exhaustive 3D comparison of the skull morphology within the genus Dasypus, based on micro-computed tomography. We used geometric morphometric approaches to explore the patterns of the intra- and interspecific morphological variation of the skull with regard to several factors such as taxonomy, geography, allometry, and sexual dimorphism. Results We show that the shape and size of the skull vary greatly among Dasypus species, with Dasypus pilosus representing a clear outlier compared to other long-nosed armadillos. The study of the cranial intraspecific variation in Dasypus novemcinctus evidences clear links to the geographic distribution and argues in favor of a revision of past taxonomic delimitations. Our detailed morphometric comparisons detected previously overlooked morphotypes of nine-banded armadillos, especially a very distinctive unit restricted to the Guiana Shield. Discussion As our results are congruent with recent molecular data and analyses of the structure of paranasal sinuses, we propose that Dasypus novemcinctus should be regarded either as a polytypic species (with three to four subspecies) or as a complex of several distinct species.

Abstract:
In this paper, a new bio-inspired metaheuristic algorithm called Giant Armadillo Optimization (GAO) is introduced, which imitates the natural behavior of giant armadillo in the wild. The fundamental inspiration in the design of GAO is derived from the hunting strategy of giant armadillos in moving towards prey positions and digging termite mounds. The theory of GAO is expressed and mathematically modeled in two phases: (i) exploration based on simulating the movement of giant armadillos towards termite mounds, and (ii) exploitation based on simulating giant armadillos’ digging skills in order to prey on and rip open termite mounds. The performance of GAO in handling optimization tasks is evaluated in order to solve the CEC 2017 test suite for problem dimensions equal to 10, 30, 50, and 100. The optimization results show that GAO is able to achieve effective solutions for optimization problems by benefiting from its high abilities in exploration, exploitation, and balancing them during the search process. The quality of the results obtained from GAO is compared with the performance of twelve well-known metaheuristic algorithms. The simulation results show that GAO presents superior performance compared to competitor algorithms by providing better results for most of the benchmark functions. The statistical analysis of the Wilcoxon rank sum test confirms that GAO has a significant statistical superiority over competitor algorithms. The implementation of GAO on the CEC 2011 test suite and four engineering design problems show that the proposed approach has effective performance in dealing with real-world applications.

Abstract:
Originally endemic to South America, the nine-banded armadillo (Dasypus novemcinctus) has recently expanded its range northward to Illinois. With this range expansion comes concern from both wildlife managers and the general public regarding potential incoming pathogens and unknown impacts on native wildlife. My research, conducted during 2018-2020 in southern Illinois, addressed the following 3 objectives intended to provide information regarding this novel species: (1) test for the presence of Trypanosoma cruzi and Mycobacterium leprae, (2) model the potential distribution of armadillos, and (3) attempt several different armadillo capture methods. For Objective 1, I tested roadkilled specimens for T. cruzi and M. leprae, 2 pathogens known to infect humans, using PCR and ELISA, respectively. All 81 samples tested for T. cruzi and all 25 samples tested for M. leprae were negative. The latter case is consistent with the enemy release hypothesis, suggesting armadillos have evaded parasites present in their native environment due to geographical distance. The absence of T. cruzi in the sampled individuals implies dispersing individuals are more robust than those at the center of their range. For Objective 2, I used MAXENT to model potential armadillo distribution in 51 counties in southern Illinois using 39 presence locations. Modeling identified low-intensity development to be the most important predictor of armadillo presence. For Objective 3, I attempted to capture armadillos using spotlighting on roads, staking out burrows, unbaited single-door cage traps, and unbaited double-door cage traps. Based on trap nights per capture, I found the use of double-door cage traps to be the most efficient method. My study will aid in managing colonizing armadillo populations by presenting information regarding dynamics of disease transmission, predicting areas of armadillo presence, and capture methods.

Memoria para optar al Título Profesional de Médico Veterinario.
Los armadillos, junto a los perezosos y osos hormigueros, pertenecen al Megaorden Xenarthra. Actualmente se conocen 20 especies de armadillos en el mundo, de las cuales sólo tres se distribuyen en Chile. Habitan, principalmente, la cuesta occidental de la cordillera de los Andes. Por el norte se distribuye el quirquincho de la puna (Chaetophractus vellerosus), en la zona centro-sur el piche (Zaedyus pichiy) y en el extremo sur el peludo (Chaetophractus villosus). A pesar de las interesantes e inusuales características que tienen estas especies a nivel anatómico, fisiológico y evolutivo, en Chile no se les ha dado la atención necesaria. Esta memoria tiene por finalidad profundizar en el conocimiento de la historia natural de estas tres especies a través de una revisión bibliográfica y evaluar su distribución real y amenazas dentro del Sistema Nacional de Áreas Silvestres Protegidas del Estado (SNASPE) de la Corporación Nacional Forestal. Para ello se recopiló la literatura existente sobre los armadillos de Chile, y se enviaron encuestas a todas las unidades del SNASPE, obteniendo un 70,5% de respuestas. La búsqueda bibliográfica mostró que se ha generado muy poca información en el país y que se han realizado pocos estudios en terreno. La distribución del piche resultó ser mucho más restringida de lo que se pensaba. Las principales amenazas en el país son el atropellamiento, el ataque por perros asilvestrados y la presencia de minerías y termoeléctricas. Esta memoria servirá como base para futuros estudios sobre estas especies en Chile
Armadillos, as well as sloths and anteaters, belong to the Superorder Xenarthra. Twenty species of armadillos are currently recognized in the world, of which only three are distributed in Chile. They inhabit mainly the western slope of the Andes. The screaming hairy armadillo (Chaetophractus vellerosus) is distributed in the north, the pichi (Zaedyus pichiy) in the south-central area of Chile, and the large hairy armadillo (Chaetophractus villosus) inhabits the far south. Despite the interesting and unusual characteristics of these species at the anatomical, physiological, and evolutionary level, Chile has not given these species the necessary attention. This report aims to deepen the knowledge about the natural history of these three species through a bibliographical review, and to evaluate their real distribution and threats within the Sistema Nacional de Áreas Silvestres Protegidas del Estado (SNASPE) of the Corporación Nacional Forestal. To accomplish this, the existing literature on the armadillos of Chile was compiled and surveys were sent to all SNASPE units, obtaining 70.5% of responses. The literature search showed that very little information has been generated in the country and that few field studies have been done. The pichi’s distribution turned out to be much more restricted than previously thought. The main threats in the country include automobiles, attacks by feral dogs, and the presence of mining and thermoelectric plants. This report will serve as a basis for future studies on these species in Chile

Paracoccidioides spp. são fungos que vivem no ambiente (solo) e em associação com tecidos de hospedeiros mamíferos. Apresentam como característica de patogenicidade o termo-dimorfismo, em que, a 25º C apresenta a fase micelial e produz suas partículas infectantes (conídios) e a 35-37º C está sob forma de leveduras (forma parasitária). As características morfológicas e micromorfológicas são importantes, mas insuficientes para a diferenciação entre os genótipos. Contudo, o avanço no conhecimento da Biologia Molecular nos últimos anos permitiu uma grande compreensão da biologia e das relações filogenéticas de Paracoccidioides spp. A região de ITS1-5.8S-ITS2 (rDNA) tem sido largamente usada na identificação de diversos fungos, sendo muito útil para discriminar entre P. brasiliensis e P. lutzii, no entanto, ela não separa entre as genótipos do complexo P. brasiliensis (S1, PS2, PS3 e PS4), no qual, recentemente foi proposto um rearranjo taxonômico, em que foram descritas como novas espécies de Paracoccidioides: P. brasiliensis para S1, P. americana para PS2, P. restrepiensis para PS3 e P. venezuelensis para PS4. Além do seqüenciamento do ITS, é necessário incluir outras regiões gênicas mais ou menos polimórficas para estudos filogenéticos que visam identificar Paracoccidioides spp. como nesse estudo. Este trabalho teve como objetivo mapear áreas de ocorrência e isolar Paracoccidioides a partir de tatus (Dasypus novemcinctus), bem com detectar molecularmente por Nested-PCR o DNA do fungo em amostras de solo e nos órgãos (baço, fígado e linfonodos mesentéricos) de tatus. Nós isolamos o fungo de tatus do Sudeste (Botucatu/SP) e Centro-Oeste (Alta Floresta/MT). Todos os isolados foram caracterizados molecularmente pelo seqüenciamento ITS-rDNA e gp43 exon 2 e por PCR-RFLP de alfa tubulina (tub1) como P. brasiliensis e P. americana. A reação de Nested-PCR foi sensível e permitiu detectar o DNA de Paracoccidioides nas amostras de tecido (baço, fígado e linfonodos mesentéricos) de D. novemcinctus e também no solo dos Estados de São Paulo e Mato Grosso. A construção filogenética com os amplicons ambientais de solo mostrou que P. lutzii está amplamente presente nessas regiões (Sudeste e Centro-Oeste), além do que, amplicons de P. lutzii de Alta Floresta/MT clusterizaram em um clado separadamente, sugerindo que espécies crípticas podem existir, dentro de P. lutzii.
Paracoccidioides spp. are fungi that live in the environment (soil) and in association with tissues of mammalian hosts. They present as a characteristic of pathogenicity the thermo - dimorphism, in which, at 25º C it presents the m ycelial phase and produces its infective particles (conidia) and at 35 - 37º C it is in the form of yeasts (parasitic form). The morphological and micromorphological characteristics are important, but insufficient for the differentiation between the genotype s. However, the advance in the knowledge of Molecular Biology in recent years has allowed a great understanding of the biology and phylogenetic relationships of Paracoccidioides spp. The region of ITS1 - 5.8S - ITS2 (rDNA) has been widely used in the identific ation of several fungi, in which it is very useful in the discrimination between P. brasiliensis and P. lutzii , however, it does not separate between genotypes of the complex P. brasiliensis (S1, PS2, PS3 and PS4), in which recently a taxonomic rearrangeme nt was proposed, described as new species of Paracoccidioides : P. brasiliensis for S1, P. americana for PS2, P. restrepiensis for PS3 and P. venezuelensis for PS4 . In addition to the sequencing of ITS, it is necessary to include other more or less polymorp hic gene regions for phylogenetic studies aimed at identifying Paracoccidioides spp. as in this study . The objective of this work was to map out occurrence areas and isolate Paracoccidioides from armadillos ( Dasypus novemcinctus ), as well as molecularly de tect the DNA of the fungus in soil samples and organs (spleen, liver and mesenteric lymph nodes) by Nested - PCR . We isolated the armadillo fungus from the Southeast (Botucatu / SP) and Central West (Alta Floresta / MT). All isolates were molecularly charac terized by ITS - rDNA and gp43 exon 2 sequencing and by alpha tubulin (tub1) PCR - RFLP as P. brasiliensis and P. americana . The Nested - PCR reaction was sensitive and allowed to detect the DNA of Paracoccidioides in tissue samples (spleen, liver and mesenteric lymph nodes) of D. novemcinctus and also in the soil of the States of São Paulo and Mato Grosso. Phylogenetic construction with environmental soil amplicons showed that P. lutzii is widely present in these regions (Southeast and Center - West), in addition, P. lutzii amplicons from Alta Floresta / MT cluster in a clade separately, suggesting that species may exist within P. lutzii .

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2009.
Includes bibliographical references (p. 37).
TCP was originally designed to function over static hosts. So, a connection is established between two IP addresses which are assumed to never change of the period of the connection. On the other hand, when TCP is deployed on mobile hosts a number of new factors that are the results of the node's mobility, such as frequent disconnections and changing IP addresses, are introduced into the model. TCP may timeout and quit as a response to these events and therefore yield a suboptimal performance. This work introduces Armadillo, a protocol to hide intermittent connectivity from TCP applications on mobile hosts to increase performance. In contrast to all the previous work to our knowledge, our protocol requires no changes to the TCP stack or application on the either end. In a typical scenario we assume that a mobile host uses a WiFi access point (AP) for internet connectivity. Because of the limited range of the AP and the mobility of the host it is going to move out of the range and disconnect. As a consequence, the TCP connection is going to timeout and finally quit. The two important problems we address in this report are the following: (1) preventing the TCP application from timing out and eventually breaking as a result of disconnections and (2) handling the switching between APs so the change of IP addresses is transparent to the TCP application. We evaluate our system under real-world conditions and discuss results.

Os tatus (Cingulata: Dasypodidae), apesar da diversidade de espécies, 21 espécies, e ampla distribuição, da Argentina até a metade sul dos EUA, passando pela América Central, as informações sobre a utilização dos ambientes por estes animais é escassa. A escavação e utilização de buracos no solo é uma característica ecológica relevante para o grupo, podendo estas estruturas serem consideradas indicadores conspícuos da presença desses animais. No presente estudo investiguei a densidade, direção, morfometria e microhabitat das tocas, em diferentes tipos de formação vegetal. O trabalho foi desenvolvido durante 13 meses (Out/06 a Nov/07) no Parque Estadual de Itapuã, na Grande Porto Alegre, RS, Brasil. O tatu-galinha (Dasypus novemcinctus) parece ser a espécie mais abundante neste local, onde ainda ocorre ao menos uma outra espécie, tatu-de-rabo-mole-grande (Cabassous tatouay). As características físicas e ambientais de 72 tocas, no campo (n = 31), mata (n = 22) e Restinga (n = 19), encontradas foram analisadas. A densidade de tocas não variou significativamente entre estes ambientes. Embora o tatu-galinha seja apontado como uma espécie de áreas florestadas no presente estudo, as áreas abertas foram utilizadas com a mesma intensidade que mata e restinga. Dentre as variáveis ambientais o número de árvores e porcentagem de cobertura de solo por arbustos tiveram influência no número de tocas encontradas em mata. A direção das tocas foram predominantemente sul nas áreas de floresta (mata e restinga) e significativamente diferentes das áreas de campo (campoXmata p = 0,002; campoXrestinga p = 0,001). Sugerindo que esta espécie possa mudar o comportamento e aumentar o nicho na ausência ou relaxamento de predadores e competidores.
Armadillos ( Cingulata : Dasypodidae ), despite the diversity of species , 21 species , and wide distribution , from Argentina to the southern half of the United States through Central America, information on the use of animals in these environments is scarce. The excavation and using holes in the ground is an important ecological nature of the group, these structures may be considered conspicuous indicators of the presence of these animals. In the present study I have investigated the density, direction, morphometric and microhabitat of the burrows in different types of plant formation. The study was conducted during 13 months (Oct/06 to Nov/07) in Itapuã State Park, in Porto Alegre , RS , Brazil . The nine-banded armadillo (Dasypus novemcinctus) seems to be the most abundant species at this site, which is still at least one other species, the greater naked-tailed armadillo (Cabassous tatouay). The physical and environmental characteristics of 72 holes, fields (n = 31), forest (n = 22) and Restinga (n = 19), found were analyzed. The density of burrows did not vary significantly between these environments. Although the nine-banded is touted as a kind of wooded areas in the present study, the open areas were used with the same intensity that forest and dunes. Among the environmental variables the number of trees and percentage of ground cover shrubs influenced the number of burrows found in the woods. The direction of the burrows were predominantly southern areas of forest (forest and Restinga) and significantly different from field areas (fieldXforest p = 0.002; fieldXrestinga p = 0.001). Suggesting that this species can change behavior and increase the niche or relaxation in the absence of predators and competitors.

Abstract:
This report describes a solution to an adjustment problem found on “The Armadillo”. This product can be described as a bicycle, but with four wheels instead of two, and has a somewhat more complex construction than an electric bicycle. In today’s construction there are difficulties in using the bike if the driver is not within the range of 170-190 cm tall, which obviously limits the user of the product. The main user are those who work with the product. The task of the project was therefore to find a solution to this problem, with free hands without major limitations. This has been done in cooperation the company that owns the product, Velove, where a couple of visits have been made to study the design further, as well as examine the possibilities and limitations that exist. Methods such as Fredy Olsson with small modification have been used, this has simplified the work as a clear structure has been obtained on approaches. The project group has used different ideas to generating and evaluating product ideas, including where we included other students for inspiration, in order to reach a promising concept within the group. Two ready-made digital prototype concepts have been developed in Catia V5, where one of them has advanced into a physical prototype in plastic material. The construction allows a longer span and allows more drivers to use today’s Armadillo. The solution is another smaller rail that goes over the today’s existing rail witch makes it possible to further adjust the length span for the driver. The construction is a superstructure on the existing Armadillo and does not require a reconstruction of the bike.

Abstract:
A tecnologia de memória persistente (PM) provê endereçamento por byte com latência de acesso relativamente próxima às das memórias voláteis (DRAM). Contudo, programar com PM traz novos desafios não encontrados em ambientes típicos com memória volátil. Neste contexto, este artigo apresenta duas contribuições principais. Primeiramente, analisamos qualitativamente as dificuldades e armadilhas de se programar com a PMDK, a biblioteca oficial da Intel para programação do Optane DC (seu dispositivo de armazenamento persistente). Esta análise é o resultado das nossas experiências coletadas durante o desenvolvimento de um conjunto de estruturas de dados típicas de aplicações com persistência de dados. A segunda contribuição é uma análise de desempenho considerando implementações persistentes e voláteis dessas estruturas de dados para DRAM, Optane DC e SSD. Os resultados experimentais mostram que o Optane DC, apesar de em média ser 5,54× mais lento que o dispositivo volátil (DRAM), supera o SSD em 14× no pior caso.

Abstract:
A presente comunicação pretende realizar algumas considerações acerca das pinturas do artista suíço Felice Varini (1952), realizadas nas superfícies de edifícios, ruas e paredes em diversas cidades do mundo. Definida pelo professor e crítico de arte Joël Koskas como uma “anti-Monalisa”, a obra de Varini constitui-se de formas geométricas que, após projetadas por canhões de luz nas paredes, tetos e demais superfícies arquitetônicas, são coloridas em tonalidades contrastantes.
