A viagem como experiência traumática na ficção Paisagem de Porcelana de Cláudia NIna
Authors: Cardoso Bruno 
Published: November 2017

Resumo:O artigo analisa a representação da experiência de deslocamento no romance Paisagem de Porcelana da escritora carioca Claudia Nina. A leitura da obra focaliza os expedientes narrativos empregados pela autora no objetivo de figurar a viagem da protagonista-narradora a Holanda sob uma moldura traumática e dramática. Assim, o enredo se constrói sob uma perspectiva memorialista, conforme Cury( 2016), comumente utilizada em narrativas de viagem. A hipótese de leitura assume que a narradora, ao passo que rememora os acontecimentos traumáticos ocorridos em sua experiência de viagem a Amsterdã, produz um discurso de ficção reparando as arestas deixadas pela experiência traumática. Em consequência disso,, a possibilidade de superar a experiência traumática de viagem se viabiliza, no romance, por intermédio da criação de uma escrita ficcional sobre ela,o que se revela como estratégia narrativa crucial para a construção do enredo.
“O profeta”, de Samuel Rawet: moldura narrativa, corte cinematográfico e cena expressionista
Authors: Pires Maria Isabel Edom , Cury Maria Zilda Ferreira 
Published: November 2017

<p> Este artigo trata dos modos de construção do conto “O profeta”, de Samuel Rawet, a partir da leitura de algumas referências intermidiáticas. Analisam-se a epígrafe, como um procedimento antecipatório e modular do conto; as imagens que convidam à leitura de elementos picturais, como as que sintetizam a viagem do imigrante e as visões da guerra oriundas do domínio expressionista, em comparação com a obra do pintor Lasar Segall; e os cortes e a montagem que indicam procedimentos cinematográficos. Tais processos apontam, segundo esta análise, para a forma seccionada como é visto o imigrante, para a disrupção da sua figura na sociedade receptora e para a dificuldade que ele encontra de partilhar a experiência da guerra. O conto enfatizaria a impossibilidade de reconhecer a inteireza do estrangeiro na condição de imigrante por meio de recursos elípticos e sinedóquicos.</p><p>Palavras-chave: Conto. Imigração.

Published: November 2017

Context.—The Ki-67 index is strongly prognostic and is used as a surrogate marker to distinguish luminal A from luminal B breast cancer types.Objective.—To investigate differences in Ki-67 index between core needle biopsy samples and matched surgical samples in breast cancer.Design.—We included patients with invasive breast cancer who did not receive neoadjuvant therapy. A total of 89 pairs of core needle biopsies and surgical specimens were collected, and the Ki-67 index was assessed in hot spot areas using an image analyzer. We applied a 14% Ki-67 index to define low versus high groups.Results.—The Ki-67 index was significantly higher in core needle biopsies than in surgical specimens (P &lt; .001), with a median absolute difference of 3.5%. When we applied 14% as a cutoff, 16 of 89 cases (18%) showed discrepancy. Thirteen cases showed a high Ki-67 index in core needle biopsies but a low Ki-67 index in surgical samples. There were 10 cases (11.2%) that showed discordant luminal A/B types between core needle biopsy and the matched surgical specimen. The reasons for the discordance were poor staining of MIB1 accompanied by fixation issues and intratumoral heterogeneity of the Ki-67 index.Conclusions.—A significant difference in the Ki-67 index between core biopsy and surgical specimens was observed. Our findings indicate that it may be better to perform the Ki-67 assay on the core needle biopsy and the surgical specimen than on only one sample.
Using Long‐Term Satellite Observations to Identify Sensitive Regimes and Active Regions of Aerosol Indirect Effects for Liquid Clouds Over Global Oceans

Published: November 2017

AbstractLong‐term (1981–2011) satellite climate data records of clouds and aerosols are used to investigate the aerosol‐cloud interaction of marine water cloud from a climatology perspective. Our focus is on identifying the regimes and regions where the aerosol indirect effects (AIEs) are evident in long‐term averages over the global oceans through analyzing the correlation features between aerosol loading and the key cloud variables including cloud droplet effective radius (CDER), cloud optical depth (COD), cloud water path (CWP), cloud top height (CTH), and cloud top temperature (CTT). An aerosol optical thickness (AOT) range of 0.13 < AOT < 0.3 is identified as the sensitive regime of the conventional first AIE where CDER is more susceptible to AOT than the other cloud variables. The first AIE that manifests as the change of long‐term averaged CDER appears only in limited oceanic regions. The signature of aerosol invigoration of water clouds as revealed by the increase of cloud cover fraction (CCF) and CTH with increasing AOT at the middle/high latitudes of both hemispheres is identified for a pristine atmosphere (AOT < 0.08). Aerosol invigoration signature is also revealed by the concurrent increase of CDER, COD, and CWP with increasing AOT for a polluted marine atmosphere (AOT > 0.3) in the tropical convergence zones. The regions where the second AIE is likely to manifest in the CCF change are limited to several oceanic areas with high CCF of the warm water clouds near the western coasts of continents. The second AIE signature as represented by the reduction of the precipitation efficiency with increasing AOT is more likely to be observed in the AOT regime of 0.08 < AOT < 0.4. The corresponding AIE active regions manifested themselves as the decline of the precipitation efficiency are mainly limited to the oceanic areas downwind of continental aerosols. The sensitive regime of the conventional AIE identified in this observational study is likely associated with the transitional regime from the aerosol‐limited regime to the updraft‐limited regime identified for aerosol‐cloud interaction in cloud model simulations.

Published: November 2017

AbstractLakes are considered as indicators of climate change on the Tibetan Plateau (TP). In the present study, we use the General Lake Model to simulate water temperature changes in Nam Co, the second largest lake on the central TP, for the period 1979–2012. The calibration and validation results demonstrate that this model is well suited for thermal simulation of Nam Co. The simulation results indicate that Nam Co has responded to the recent warming climate. The average summer surface water temperature fluctuated yearly, but its trend is positive at a rate of 0.52 ± 0.25°C per decade. At the same time, the onset of summer stratification advanced by 4.20 ± 2.02 d per decade, and the duration increased at a rate of 6.00 ± 3.54 d per decade. To explore the roles of air temperature and longwave radiation in lake warming, three sensitivity experiments are conducted by removing long‐term trends from time series of air temperature and longwave radiation in the forcing data. These experiments prove that both increased air temperature and downward longwave radiation are two driving factors responsible for the warming of Nam Co.

Authors: Després Philippe , Gaede Stewart 
Published: November 2017

AbstractThe Canadian Organization of Medical Physicists (COMP), in close partnership with the Canadian Partnership for Quality Radiotherapy (CPQR) has developed a series of Technical Quality Control (TQC) guidelines for radiation treatment equipment. These guidelines outline the performance objectives that equipment should meet in order to ensure an acceptable level of radiation treatment quality. The TQC guidelines have been rigorously reviewed and field tested in a variety of Canadian radiation treatment facilities. The development process enables rapid review and update to keep the guidelines current with changes in technology (the most updated version of this guideline can be found on the CPQR website). This particular TQC details recommended quality control testing of CT simulators.
Dynamically Gas‐Phase Switchable Super(de)wetting States by Reversible Amphiphilic Functionalization: A Powerful Approach for Smart Fluid Gating Membranes

Published: November 2017

AbstractIn nature, cellular membranes perform critical functions such as endocytosis and exocytosis through smart fluid gating processes mediated by nonspecific amphiphilic interactions. Despite considerable progress, artificial fluid gating membranes still rely on laborious stimuli‐responsive mechanisms and triggering systems. In this study, a room temperature gas‐phase approach is presented for dynamically switching a porous material from a superhydrophobic to a superhydrophilic wetting state and back. This is realized by the reversible attachment of bipolar amphiphiles, which promote surface wetting. Application of this reversible amphiphilic functionalization to an impermeable nanofibrous membrane induces a temporary state of superhydrophilicity resulting in its pressure‐less permeation. This mechanism allows for rapid smart fluid gating processes that can be triggered at room temperature by variations in the environment of the membrane. Owing to the universal adsorption of volatile amphiphiles on surfaces, this approach is applicable to a broad range of materials and geometries enabling facile fabrication of valve‐less flow systems, fluid‐erasable microfluidic arrays, and sophisticated microfluidic designs.

Published: November 2017

AbstractShort‐wavelength light‐emitting diodes (LEDs), a prevalent research topic in modern optoelectronics, have attracted considerable attention in recent years because of their vast application potential in both civil and military domains. Herein, blue‐violet LEDs are constructed via a spin‐coating solution‐processed ZnO quantum dots (QDs) onto p‐GaN: Mg wafers. By inserting a thin Al2O3 dielectric retarding layer into the ZnO QDs side, electrons injected from ITO cathode are effectively slowed and detained in the QDs emissive layer, resulting in a ≈30‐fold improvement of near‐UV electroluminescence intensity from this p‐GaN/ZnO QDs/Al2O3/ZnO QDs LED. Furthermore, by replacing pure ZnO QDs with Ag@ZnO hybrid nanodots (synthesized through a simple one‐step wet chemical route) as the electron transport layer, the device electroluminescence intensity is further increased. Time‐resolved and temperature‐dependent spectroscopy reveals that both the spontaneous emission rate and internal quantum efficiency of the ZnO QDs active layer are simultaneously increased as a result of the exciton‐localized surface plasmon resonant coupling, which leads to the observed blue‐violet electroluminescence enhancement.

Published: November 2017

AbstractSince their successful commercialization in 1990s, lithium‐ion batteries (LIBs) have been widely applied in portable digital products. The energy density and power density of LIBs are inadequate, however, to satisfy the continuous growth in demand. Considering the cost distribution in battery system, it is essential to explore cathode/anode materials with excellent rate capability and long cycle life. Nanometer‐sized electrode materials could quickly take up and store numerous Li+ ions, afforded by short diffusion channels and large surface area. Unfortunately, low thermodynamic stability of nanoparticles results in electrochemical agglomeration and raises the risk of side reactions on electrolyte. Thus, micro/nano and hetero/hierarchical structures, characterized by ordered assembly of different sizes, phases, and/or pores, have been developed, which enable us to effectively improve the utilization, reaction kinetics, and structural stability of electrode materials. This review summarizes the recent efforts on electrode materials with hierarchical structures, and discusses the effects of hierarchical structures on electrochemical performance in detail. Multidimensional self‐assembled structures can achieve integration of the advantages of materials with different sizes. Core/yolk–shell structures provide synergistic effects between the shell and the core/yolk. Porous structures with macro‐, meso‐, and micropores can accommodate volume expansion and facilitate electrolyte infiltration.

Published: November 2017

AbstractA tandem [1,2]‐Wittig rearrangement/lactonization of γ‐benzyloxy vinylogous urethanes is presented herein. The resulting butenolides featuring various benzyl substituents at the γ‐position are structurally diverse compounds found in natural products. The usefulness of this synthetic approach was demonstrated in the formal synthesis of maculalactone A, rapid assembly of the tricyclic core of planchol C, and the total synthesis of γ‐lycorane.

BackgroundEar symptoms are common among patients presenting to a rhinology clinic. Validated inventories are available for patient quality‐of‐life in sinonasal disease and Eustachian tube dysfunction (ETD). This study sought to determine the extent of ETD symptoms, using validated metrics, in a large population of patients presenting to a tertiary rhinology clinic.MethodsSeven‐item Eustachian Tube Dysfunction Questionnaires (ETDQ‐7) and 22‐item Sino‐Nasal Outcome Tests (SNOT‐22) were prospectively collected from 492 patients treated in a tertiary rhinology clinic. Patient diagnoses were retrospectively determined from the medical record. Correlation between reported SNOT‐22 and ETDQ‐7 scores were analyzed, in addition to the number of patients meeting the criterion score for ETD.ResultsA total of 213 patients reported mean ETDQ‐7 scores >2.1, consistent with a diagnosis of ETD. Overall SNOT‐22 scores were strongly correlated with ETDQ‐7 scores (r = 0.679, p < 0.001). The SNOT‐22 ear subdomain was very strongly correlated with the ETDQ‐7 score (r = 0.847, p < 0.001), while there was a moderate correlation with the SNOT‐22 rhinologic subdomain (r = 0.486, p < 0.001). Patients with allergic fungal sinusitis had decreased ETDQ‐7 scores compared to patients with other rhinologic diagnoses (p = 0.010).ConclusionSymptoms of ETD are common in patients treated in a rhinology clinic, with 43.3% of patients reporting symptom scores consistent with a formal diagnosis of ETD. Increased SNOT‐22 scores are correlated with increased ETDQ‐7 scores, even when only the SNOT‐22 rhinologic subdomain is considered. Patients presenting for treatment of rhinologic symptoms likely have an increased prevalence of otologic symptoms and ETD.

AbstractWhile chemical communication plays a key role in diverse natural processes, the intelligent chemical communication between synthetic nanomotors remains unexplored. The design and operation of bioinspired synthetic nanomotors is presented. Chemical communication between nanomotors is possible and has an influence on propulsion behavior. A chemical “message” is sent from a moving activator motor to a nearby activated (receiver) motor by release of Ag+ ions from a Janus polystyrene/Ni/Au/Ag activator motor to the activated Janus SiO2/Pt nanomotor. The transmitted silver signal is translated rapidly into a dramatic speed change associated with the enhanced catalytic activity of activated motors. Selective and successive activation of multiple nanomotors is achieved by sequential localized chemical communications. The concept of establishing chemical communication between different synthetic nanomotors paves the way to intelligent nanoscale robotic systems that are capable of cooperating with each other.

Published: November 2017

AbstractMetamaterials have optical properties that are unprecedented in nature. They have opened new horizons in light manipulation, with the ability to bend, focus, completely reflect, transmit, or absorb an incident wave front. Optically active metamaterials in particular could be used for applications ranging from 3D information storage to photovoltaic cells. Silicon (Si) particles are some of the most promising building blocks for optically active metamaterials, with high scattering efficiency coupled to low light absorption for visible frequencies. However, to date ideal Si building blocks cannot be produced by bulk synthesis techniques. The key is to find a synthetic route to produce Si building blocks between 75–200 nm in diameter of uniform size and shape, that are crystalline, have few impurities, and little to no porosity. This Review provides a theoretical background on Si optical properties for metamaterials, an overview of current synthetic methods and gives direction towards the most promising routes to ideal Si particles for metamaterials.

Published: November 2017

AbstractThe first successfully controlled radical polymerization (CRP) of ethylene is reported using several organotellurium chain‐transfer agents (CTAs) under mild conditions (70 °C, 200 bar of ethylene) within the concept of organotellurium‐mediated radical polymerization (TERP). In contrast to preceding works on CRPs of ethylene applying reversible addition–fragmentation chain‐transfer (RAFT), the TERP system provided a high livingness and chain‐end functionalization of polyethylene chains. Molar‐mass distributions with dispersities between 1.3 and 2.1 were obtained up to average molar masses of 5000 g mol−1. As in the RAFT system, the high reactivity of the growing polyethylenyl radical led to an inherent side reaction. For the presented TERP systems, however, this side reaction did not result in dead chains, while it could even be effectively suppressed by a good choice of the CTA.
Review: Defining a Unified Vascular Phenotype in Systemic Sclerosis

Published: November 2017

Microcirculation impairment and related vasculopathy are hallmarks of systemic sclerosis (SSc). Digital ulceration is second only to Raynaud's phenomenon as a vascular complication occurring in patients with SSc. Digital ulcers are painful and generate disability. Furthermore, patients may develop recurrent digital ulcers, and it is reasonable to question whether the outcomes of such patients might be different from those of patients who are not affected. Recently, several registries have provided relevant information about digital ulcers. Male sex and severe skin disease appear to be the main associated factors observed in several registries. However, limitations of those studies are the differences in the definitions of digital ulcers and organ involvement. Few longitudinal studies are available, and the more robust data from the European League Against Rheumatism Scleroderma Trial and Research cohort suggested worse outcomes in patients with a history of digital ulcers but could not demonstrate that a history of digital ulcers can predict additional vascular complications such as pulmonary arterial hypertension, heart failure, or renal crisis. Nevertheless, the autopsy studies published many years ago and the more recent longitudinal biomarker studies support the concept of generalized vasculopathy and a potential association between various cardiovascular complications. It is expected that with the availability of several structured registries, identification of a vascular profile or vascular phenotype will be addressed using more robust data in the near future.

Published: November 2017

AbstractObjectivesMultiple sclerosis (MS) is the most frequent immune‐mediated inflammation of the central nervous system that can lead to early disability. Headaches have not been considered as MS‐related symptoms initially, whereas higher prevalence rates were reported since 2000. Postmortem histological analyses of MS patients’ brains revealed lymphoid follicle‐like structures in the cerebral meninges which suggest a possible pathophysiological explanation for the high headache prevalence in MS. The aim of this study was to evaluate headache characteristics during the first clinical event of MS.MethodsIn a prospective, multicenter study, 50 patients with the diagnosis of CIS or MS were recruited. All participants were screened for the presence of headache within the last 4 weeks with help of the Rostock Headache Questionnaire (Rokoko).ResultsThirty‐nine of fifty questioned patients (78%) reported headaches within the last 4 weeks. Most patients suffered from throbbing and pulsating headaches (25, 50%), 15 (30%) reported stabbing, 14 (28%) dull and constrictive headaches.ConclusionsHeadaches were prevalent in 78% of patients in our population with newly diagnosed CIS and MS. It is among the highest prevalence rates reported so far in patients with CIS or MS. Thus, headache, especially of a migraneous subtype, is a frequent symptom within the scope of the first manifestation of multiple sclerosis. If it were possible to define a MS‐typical headache, patients with these headaches and with typical MRI results would be classified as CIS or early MS instead of radiologically isolated syndrome and treated accordingly with an immunomodulatory therapy.

Published: November 2017

Key Clinical MessageCoughing could induce symptomatic, frequent atrial premature contractions (APCs), and episodes of atrial tachycardia (AT) in a rare case. If multiple arrhythmic drugs therapy failed to control the symptoms, catheter ablation was an effective therapeutic option for abolishing such atrial tachyarrhythmias guided by the electroanatomic mapping systems.
