Authors: Da Costa Antonio Jaldesmar , Lopes Rosa Maria Rodrigues , Rodrigues João Freire 
Published: May 2017

O presente artigo objetiva analisar a influência da segunda residência na dinâmica urbana e turística da cidade de Portalegre (Rio Grande do Norte/RN, Brasil). O estudo inicia com um breve histórico sobre a temática, discutindo, os objetivos específicos que serão direcionados para composição dos aspectos históricos e teóricos sobre Segunda Residência e as mudanças no espaço urbano e turístico em decorrência da instalação destas, neste município. A pesquisa com metodologia descritiva analítica e abordagem quali-quantitativa, foi norteada através de entrevistas com os representantes do Poder Público e loteamento Varandas da Serra, e formulários semiestruturados aplicados com os turistas de segunda residência durante os finais de semana. Vale salientar, que a temática mereceu ser aprofundada devido os poucos estudos na área, principalmente direcionados a segunda residência em cidades serranas potiguares. Através das pesquisas em campo, os resultados apontaram para o fato de que o turismo contribuiu de forma efetiva para o crescimento das segundas residências, e, consequentemente para o aumento da valorização do uso do solo e ampliação da demanda por equipamentos e serviços urbanos. No entanto, percebeu-se que após o ano de 2012, as ações aconteceram de forma limitada, tendo em vista as precárias condições financeiras por parte do Poder Público. Ainda assim, os turistas estavam optando pelo município, motivados principalmente, pelas amenidades naturais que justificam uma melhor tranquilidade para momentos de descanso. Portanto, entende-se que a cidade estava dispondo de uma diversidade de elementos naturais, urbanos e turísticos, favorecendo o crescimento do turismo e das segundas residências e acentuando a dinâmica urbana local.

Authors: Nielsen Jeanette Lykkegård 
Published: May 2017

Fænomenet social smitte undersøges gennem en animistisk ramme, hvori agenter såsom ånder skal forstås som reelle verdslige væsner med konkret indflydelse på menneskers liv. Artiklens omdrejningspunkt er et problemfyldt alkoholmisbrug i landsbyen Achaivayam i det nordlige Kamchatka, Russisk Fjernøsten og spredning heraf. Forståelsen af socialitet og sygdomme som et socialt fænomen udvides, hvorved der åbnes op for nye måder at forstå ikke-smitsomme sygdommes evne til at smitte og spredes. Alcohol and Relationality: Social Contagion as an Animistic Phenomenon in Siberia The phenomenon of ’social contagion’ is explored through an animistic framework, in which agents, such as spirits, are to be understood as real beings with tangible effects on people’s lives. The article revolves around a problematic alcohol abuse and it’s spreading in the village of Achaivayam in Northern Kamchatka, Russian Far-East. The understanding of sociality as well as illness and disease as a social phenomenon is extended, thereby opening up for new ways of understanding the ability of ’non-communicable’ diseases to communicate and spread.
Traumer og ånder efter krig i Uganda: Konfigurationer af vold og behandling
Authors: Williams Lars Hedegaard , Meinert Lotte 
Published: May 2017

I kølvandet på 20 års borgerkrig i det nordlige Uganda fulgte en bølge af traumer, onde ånder og vold, som fortsat forpester livet og fordrer handling. Brutaliteten og de mange ubegravede lig som krigen efterlod, opleves af mange som årsag til forskellige former for åndelig og social kontaminering. I en biomedicinsk forståelse beskrives forstyrrelserne som Post Traumatisk Stress Syndrom (PTSD), hos de traditionelle behandlere (ajwaki) kaldes fænomenerne cen, og i kirkerne betragtes problemerne som djævlens værk. Der er bred enighed mellem de forskellige tilgange om, at noget er galt, og folk lider herunder, men de varierende begrebsliggørelser af problemerne peger mod forskellige handlemuligheder. Igennem en fyldig skildring af en enkelt case analyserer vi disse problemer og behandlingsformer med begreber om social smitte, kontaminering, og konfigurationer. Vi argumenterer med begrebet konfiguration for, at problemer med traumer og ånder både konstitueres af krigens vold og de forskelligartede, men begrænsede behandlingsmuligheder, som er tilgængelig i det nordlige Uganda i dag.Trauma and spirits after war in Uganda: Configurations of violence and treatmentIn the aftermath of 20 years of civil war in northern Uganda lives in the Acholi-region are still polluted by trauma, evil spirits and violence. The brutality and the many unburied bodies left behind by the war are experienced by many as the reason for a variety of forms of social and spiritual pollution. These maladies are understood as PTSD in biomedical terms, as the spirit possession cen by local, traditional healers and as the work of the devil within the many churches. There is a broader agreement between these different positions that something is wrong and that families and individuals are suffering, but the variety of conceptualizations of the problems point towards different paths of action. In presenting an analysis of these problems and forms of treatment, by applying the concepts of social contagion, contamination and configurations. We argue with the concept of configuration, that problems with trauma and spirits are constituted both by the violence of the war and the various, but limited treatment options that are available in northern Uganda today.

AbstractPurposePartial stereotactic ablative boost radiotherapy (P‐SABR) effectively treats bulky lung cancer; however, the planning process for P‐SABR requires repeated dose calculations. To improve planning efficiency, we proposed a novel deep learning method that utilizes limited data to accurately predict the three‐dimensional (3D) dose distribution of the P‐SABR plan for bulky lung cancer.MethodsWe utilized data on 74 patients diagnosed with bulky lung cancer who received P‐SABR treatment. The patient dataset was randomly divided into a training set (51 plans) with augmentation, validation set (7 plans), and testing set (16 plans). We devised a 3D multi‐scale dilated network (MD‐Net) and integrated a scale‐balanced structure loss into the loss function. A comparative analysis with a classical network and other advanced networks with multi‐scale analysis capabilities and other loss functions was conducted based on the dose distributions in terms of the axial view, average dose scores (ADSs), and average absolute differences of dosimetric indices (AADDIs). Finally, we analyzed the predicted dosimetric indices against the ground‐truth values and compared the predicted dose‐volume histogram (DVH) with the ground‐truth DVH.ResultsOur proposed dose prediction method for P‐SABR plans for bulky lung cancer demonstrated strong performance, exhibiting a significant improvement in predicting multiple indicators of regions of interest (ROIs), particularly the gross target volume (GTV). Our network demonstrated increased accuracy in most dosimetric indices and dose scores in different ROIs. The proposed loss function significantly enhanced the predictive performance of the dosimetric indices. The predicted dosimetric indices and DVHs were equivalent to the ground‐truth values.ConclusionOur study presents an effective model based on limited datasets, and it exhibits high accuracy in the dose prediction of P‐SABR plans for bulky lung cancer. This method has potential as an automated tool for P‐SABR planning and can help optimize treatments and improve planning efficiency.

ObjectiveThe objective of this study was to describe the frequency, co‐occurrence, and cancer association of anti–cell division cycle and apoptosis regulator 1 (anti‐CCAR1) and anti‐Sp4 in two large independent adult dermatomyositis (DM) cohorts.MethodsAnti–transcription intermediary factor 1γ (anti‐TIF1γ)–positive patients with DM from two independent cohorts were studied to determine the serologic overlap of anti‐CCAR1 and anti‐Sp4 autoantibodies measured by enzyme‐linked immunosorbent assay. Associations between cancer‐associated myositis (CAM) and antibody‐defined subgroups within anti‐TIF1γ–positive patients with DM were determined.ResultsA total of 305 anti‐TIF1γ–positive patients with DM were studied: 169 patients from Johns Hopkins and 136 patients from Stanford. In each cohort, approximately one‐third of anti‐TIF1γ–positive patients with DM were anti‐Sp4 positive, one‐third were anti‐CCAR1 positive, 20% were positive for both, and half of patients were negative for both. There was a strong association with CAM in patients lacking both these antibodies (Johns Hopkins, odds ratio [OR] 12.9 [95% confidence interval (CI) 3.6–89.5]; Stanford, OR 4.5 [95% CI 1.8–13.2]). The strongest negative association with CAM was found in patients with anti‐Sp4 or anti‐CCAR1 (Johns Hopkins, OR 0.07 [95% CI 0.01–0.27]; Stanford, OR 0.22 [95% CI 0.07–0.55]).ConclusionBoth anti‐Sp4 and anti‐CCAR1 autoantibody subgroups are negatively associated with CAM. Although the magnitude of this association is substantial, cancer occasionally occurs in patients positive for either specificity. Conversely, approximately half of anti‐TIF1γ–positive patients with DM are negative for both antibodies (anti‐Sp4/anti‐CCAR1 negative), and thus this subgroup may warrant more intensive cancer surveillance.

AbstractThe main challenge for aqueous zinc‐ion capacitors is the low stability of zinc anode. In this study, a Prussian blue analog (PBA) has been coated on the surface of zinc foil to create an inorganic protective layer. This layer features a three‐dimensional open microporous structure, which not only endows it with excellent pseudocapacitive properties but also serves as an effective barrier against dendrite growth. The presence of PBA coating can increase the nucleation point of zinc ions and provide a low‐energy barrier for the rapid migration of zinc ions. Hence, the PBA@Zn ||PBA@Zn symmetric cell exhibits exceptional cycling stability, enduring over 1400 h of operation at a current density of 1 mA cm−2 and a capacity of 1 mAh cm−2. The PBA@Zn||AC capacitor demonstrated a discharge capacity of 46.23 mAh g−1 after 10 000 cycles at a current density of 1 A g−1, with a capacity retention of 92.41%, whereas the discharge capacity of Zn||AC capacitor is only 16.02 mAh g−1, with a capacity retention of 23.13%. The PBA@Zn||AC capacitor exhibited remarkable endurance and stability, retaining a substantial discharge capacity of 32.7 mAh g−1 after 10 000 cycles at 10 A g−1. Density Functional Theory (DFT) calculations also show that PBA has a strong interaction with Zn and exhibits superior zincophilic ability. This study reports industrially applicable low‐cost Prussian blue analogs as artificial interfacial protective layers for improving the cycling stability of zinc anode with a low‐energy barrier for rapid migration of zinc ions especially at high current density.

AbstractNowadays, the demand for portable micro‐energy storage devices with high energy density and scalable printing with cost‐effective fabrication for microsupercapacitors (MSC) are essential. Furthermore, the urgent need for this high‐performance MSC to meet all industrial sector requirements are very challenging. Herein, the screen printable MSC with high energy density is demonstrated by using copper hexacyanocobaltate (CuHCCo) derived (Cu,Co)Se2 nanocubes as the positive electrode and Ti‐MXene (Ti3C2Tx) as the negative electrode. The prepared battery type (Cu,Co)Se2 nanocubes greatly enhance the high electrochemical activity and active surface area. As a result, it delivers a high specific capacity of 602 C g−1 at the current density of 1 A g−1. The fabricated screen printable asymmetric MSC has enhanced ion‐to‐electron transfer in printable microelectrodes with numerous electrochemical active sites and delivered the high areal capacitance of 58 mA cm−2 at the current density of 1 mA cm−2 with a wide potential window. The device gives a high energy density of 8.06 µWh cm−2 and a high power density of 5 mW cm−2. These results demonstrate the new strategies of fabricating electrode materials in screen printable asymmetric MSC and show promising in microscale energy storage devices in the miniaturized devices with sustainable self‐powered compatibility.

AbstractFast‐charging lithium‐ion batteries are pivotal in overcoming the limitations of energy storage devices, particularly their energy density. There is a burgeoning interest in boosting energy storage performance through enhanced fast‐charging capabilities. However, the challenge lies in developing batteries that combine high rates, long cycle life, high capacity, and safety. This review emphasizes the importance of fundamentals and design principles of fast charging, identifying the transport of ion/electron within the electrodes/electrolytes' bulk phase and at phase boundaries as the crucial rate‐limiting steps for fast charging. Such as ion transport tunnel regulation, interfacial modification, defect engineering and multiphase systems, various optimization strategies improve the stable and exceptional electrochemical reaction kinetics for electrodes. Constructing stable solid electrolyte interfaces and adjusting solvation structures further enhance the Li+ diffusion kinetics of electrolytes. The review critically assesses the impacts and limitations of these strategies, suggesting future research directions and insights for advancing fast‐charging lithium‐ion batteries. It is anticipated that this review will inspire and guide the systematic evolution of fast‐charging technologies.

AbstractVascular grafts, widely utilized in managing cardiovascular diseases (CVD), are susceptible to postoperative complications. Recent strides in intelligent vascular grafts leveraging flexible bioelectronics enable hemodynamic and vascular health monitoring. However, their practical application faces challenges, notably biomechanical compatibility and endothelialization. Here, an all‐in‐one piezoelectric vascular graft (PVG) constructed by encapsulating a polyvinylidene fluoride (PVDF) nanofiber mat with patterned silver nanowire (AgNW) electrodes between two layers of polycaprolactone (PCL) nanofiber mats is presented. The meticulously optimized PVG, featuring PVDF and PCL nanofibers with average diameters of ≈950 and 250 nm, respectively, showcases remarkable endothelialization and mechanical performance akin to native blood vessels. The exquisite piezoelectric properties of PVDF nanofibers imbue PVG with outstanding mechanical sensing capabilities, boasting a sensitivity of 11 mV kPa−1 and stability exceeding 50 000 cycles, facilitating precise hemodynamic monitoring. Notably, artificial artery model tests demonstrate PVG's ability to diagnose vascular health status accurately based on detected hemodynamic data. Furthermore, the developed PVG exhibits nontoxicity, good hemocompatibility (hemolytic ratio < 1%), and histocompatibility. This pioneering technology, validated through ex vivo and in vivo experiments, represents a significant stride in precise vascular health management, unlocking diverse potential applications.

Published: October 2024

AbstractStacking different layers into van der Waals heterostructures (vdWHs) provides an attractive approach to integrating intrinsic prominent properties of the constituents. Mixed‐dimensional vdWHs that can interact with external fields are particularly intriguing because they host interlayer excitons (IXs) and thereby exhibiting rich physical phenomena and novel device behaviors. However, previous studies of IXs have primarily focused on TMDs systems, leaving the excitonic phenomena and correlated physics in perovskite heterostructures poorly understood. Here, the 2D‐3D ((BA)2PbBr4‐CsPbBr3) single‐crystalline perovskite vdWHs are designed to discover the modulation effects of IX states on the optical and optoelectronic properties. Interestingly, the vdWHs exhibit a newly emerging IXs emission at 546 nm and an obvious broadening phenomenon in FWHM. The vdWHs‐based photodetectors display novel light‐state rectification behaviors that can change the output photocurrents from fully off states to rectified states after illumination, resulting in a high rectification ratio up to 24342 and an obvious enhanced on/off ratio of 7000. The attractive results are attributed to the presence of IX states, which facilitate carrier hopping at the interfaces. This work establishes mixed‐dimensional single‐crystalline perovskite heterolayers as a highly adaptable platform for exciton research and applications.

AbstractEndowing artificial muscles with perceptual function, as an octopus does, is highly desired but still suffering from interfacing mismatch between actuating and sensing units in a thin fiber. Herein, an artificial neuromuscular fiber capable of electrically responding to external strain/temperature and actuation path with power supply is reported by using polymer‐assisted metal deposition to firmly coat Cu nanoparticles on the surface of liquid crystal elastomer (LCE). The LCE core acts as an actuator, while the wrinkled Cu sheath provides environment interaction and actuation monitoring. Benefiting from the levodopa/polyethyleneimine interface design, this fiber exhibits large reversible contraction (47.61%), fast strain rate (370% s−1), high output power density (663.75 W kg−1) and reliable durability (1000 cycles) under electrical stimulation. Furthermore, by combining as‐made fiber arrays with electronic system and computing algorithm, this machine learning‐assisted artificial neuromuscular system can actuate the Chinese shadow puppetry and recognize its body movements with high accuracy. This work paves a revolutionary way for fabricating next‐generation flexible robots.

Published: October 2024

AbstractLayered double hydroxides (LDHs) are promising electrode materials for alkaline electrochemical energy storage (EES). However, their low capacity, sluggish rate performance, and limited cycle life significantly hinder practical applications. This study unlocks the direct deprotonation reaction pathway for LDH materials through theoretical calculations. Guided by this insight, a novelly hierarchical composite (LDH−TPA) with various dimensions and components is fabricated by introducing terephthalic acid (TPA), serving as a superior cathode material for alkaline EES devices. Experimental results and theoretical investigations reveal the transformation process for metal–organic framework quantum dots (MOF−QDs) and the enhanced mechanism of reaction kinetics in the LDH−TPA electrode. Benefiting from the reduced deprotonation barrier, optimized electronic structure, and fast electrons/ions transport rates, the LDH−TPA1 electrode demonstrates a high specific capacity of 267 mAh g−1 at 1 A g−1 and retains 167 mAh g−1 even at 20 A g−1, along with excellent cycling stability. Furthermore, an alkaline nickel−zinc battery (AZB) with LDH−TPA1 cathode is assembled, achieving a lifespan exceeding 3400 cycles, and a high energy density of 341.3 Wh kg−1 at a power density of 1640.9 W kg−1. This study is expected to provide new insight into the modification of LDHs and the advancement of alkaline energy systems.
