SIGNIFICAÇÃO E (RE)SIGNIFICAÇÃO: OS PROCESSOS ALTERNATIVOS DE SIGNIFICAÇÃO DE UM SUJEITO AFÁSICO
Authors: Silva Jaqueline Almeida 
Published: October 2021

Esta dissertação tem como principal objetivo discutir acerca das questões ligadas subjetividade que emerge através dos processos alternativos de significação do sujeito afásico. Este é um estudo de caso pautado na perspectiva do acompanhamento longitudinal do sujeito SS, afásico, 48 anos e que utiliza os processos alternativos de significação para conseguir expressar o dito intencionado. À luz dos pressupostos da Neurolinguística Enunciativa[1]Discursiva - NED, proposta por Coudry (1986), traçamos uma discussão que envolve os sujeitos afásicos enquanto sujeitos da linguagem e aliamos aos estudos filosóficos de Bakhtin (1929/2006) que nos mostra que a subjetividade dos indivíduos é proveniente das situações sócio-histórico-culturais que o cercam. Analisar o sujeito a partir da filosofia da linguagem bakhtiniana foi de suma importância, pois essa teoria abarca a heterogeneidade do sujeito, a alteridade, interação, como algo que constitui a subjetividade humana. E todo esse processo é mediado pela linguagem. Para a coleta e análise dos dados utilizamos a teoria do paradigma indiciário proposta por Carlo Ginzgurg (1989) e a perspectiva de dado-achado, formulada por Coudry (1986). Portanto compreender as questões que envolvem a expressão da subjetividade através dos percursos enunciativos é necessário para que o olhar lançado sobre o indivíduo com afasia não seja de incompreensão, mas que esse sujeito seja visto como alguém que pode interagir a partir de situações discursivas.

AbstractIn this study, prototypicality of the aggressor was tested as a group‐level factor predicting social media users’ active participation in cyberaggression. Participants were exposed to a fictitious conversation, in which either a prototypical versus non‐prototypical user posted an aggressive comment as a reply to a provocative comment. In line with self‐categorization theory, we hypothesized that bystander participants would post an aggressive comment and rate the aggression as acceptable to a greater extent in the prototypical than in the non‐prototypical condition. Furthermore, we predicted that perceived normativity of aggression would mediate the effect of prototypicality. Results supported these predictions and showed that prototypical members affect the extent to which collective aggressive behaviors in online interactions are approved and enacted. These findings highlight the importance of group‐level factors in the study of cyberaggression and provide important information for understanding the psychological underpinnings of collective forms of online aggression.

AbstractHydrogen sulfide (H2S) detection with high selectivity and low working temperature is of great significance due to its strong toxicity both to the environment and to humans and also as an endogenous signaling molecule existing in various physiological processes. 2D perovskites with high carrier mobility are promising candidates for gas sensing; however, the development of stable and nontoxic 2D perovskites nanosheets still remains a challenge. Herein, 2D all‐inorganic NbWO6 perovskite nanosheets with thicknesses down to 1.5 nm are synthesized by liquid exfoliation, and the gas‐sensing performance based on these ultrathin nanosheets is investigated. A few‐layer NbWO6‐based sensor exhibits fast H2S sensing speed (<6 s) with high selectivity and sensitivity (S = 12.5 vs 50 ppm) at low temperature (150 °C). A small variation of H2S concentration (<0.5 ppm) can be detected with a fully reversible resistance signal. This work sheds light on the development of high‐performance gas sensors working in ambient conditions based on low‐dimensional, nontoxic, and wide‐bandgap perovskite semiconductors. The high carrier mobility, ultrathin structure, and soft nature make this type of 2D perovskite semiconductor an ideal material candidate for the fabrication of flexible, transparent, and wearable sensing devices in the future.
Design of Materials Configuration for Optimizing Redox‐Based Resistive Switching Memories
Authors: Chen Shaochuan , Valov Ilia 
Published: October 2021

AbstractRedox‐based resistive random access memories (ReRAMs) are based on electrochemical processes of oxidation and reduction within the devices. The selection of materials and material combinations strongly influence the related nanoscale processes, playing a crucial role in resistive switching properties and functionalities. To date, however, comprehensive studies on device design accounting for a combination of factors such as electrodes, electrolytes, and capping layer materials related to their thicknesses and interactions are scarce. In this work, the impact of materials’ configuration on interfacial redox reactions in HfO2‐based electrochemical metallization memory (ECM) and valence‐change memory (VCM) systems is reported. The redox processes are studied by cyclic voltammetry, and the corresponding resistive switching characteristics are investigated. In ECM cells, the overall cell resistance depends on the electrocatalytic activity of the counter electrode. Nonetheless, the capping layer material further influences the cell resistance and the SET and RESET voltages. In VCM systems, the influence of the electrode material configuration is also pronounced, and is capable of modulating the active resistive switching interface. For both types of memory cells, the switching behavior changes significantly with variation of the oxide thickness. The results present important materials selection criteria for rationale design of ReRAM cells for various memristive applications.

AbstractEmbolization is a catheter‐based minimally invasive procedure that deliberately occludes diseased blood vessels for treatment purposes. A novel silk‐based embolic material (SEM) that is developed and optimized to provide tandem integration of both embolization and the delivery of therapeutics is reported. Natural silk is processed into fibroin proteins of varying lengths and is combined with charged nanoclay particles to allow visibility and injectability using clinical catheters as small as 600 μm in diameter at lengths >100 cm. SEMs loaded with fluorochrome labeled bovine albumin and Nivolumab, which is among the most used immunotherapy drugs worldwide, demonstrate a sustained release profile in vitro over 28 days. In a porcine renal survival model, SEMs with labeled albumin and Nivolumab successfully embolize porcine arteries without recanalization and lead to the delivery of both albumin and Nivolumab into the interstitial space of the renal cortex. Mechanistically, it is shown that tissue delivery is most optimal when the internal elastic membrane of the embolized artery is disrupted. SEM is a potential next‐generation multifunctional embolic agent that can achieve embolization and deliver a wide range of therapeutics to treat vascular diseases including tumors.

AbstractPerovskite nanocrystals (NCs) are considered as the next‐generation platforms for optoelectronic applications, but their poor stability greatly restricts their development. Here, we present a facile composite strategy to synthesize highly stable CsPbBr3/Pb‐MA composite by in situ embedding the CsPbBr3 NCs in a C16H14Br2O6Pb2 (Pb‐MA) organometallic compound (MOC). The CsPbBr3/Pb‐MA composite powders show intense green emission at 519 nm, with a photoluminescence quantum yield of about 48.5% and a full width at half‐maximum of about 17 nm. More interestingly, benefitted from the protection of MOC, the CsPbBr3/Pb‐MA composites can maintain 43% and 83% of initial intensity after being illuminated under blue light for 36 h and being immersed in water for 192 h, respectively. Compared to the original CsPbBr3 NCs, the light/water stability of CsPbBr3/Pb‐MA composites is enhanced by about 40 and 700 times (the PL intensities maintain at about 60% of the initial one), respectively. As a proof‐of‐concept, the as‐fabricated devices exhibit a wide color gamut, 97.7% and 98.2% of Rec. 2020 for white light‐emitting diodes and laser diodes, respectively. These findings demonstrate that the combination of MOC and perovskite NCs is an optimized strategy for the exploitation of high‐performance perovskite composites for their future optoelectronic applications.

Published: October 2021

AbstractMagnetically responsive structured surfaces enabling multifunctional droplet manipulation are of significant interest in both scientific and engineering research. To realize magnetic actuation, current strategies generally employ well‐designed microarrays of high‐aspect‐ratio structure components (e.g., microcilia, micropillars, and microplates) with incorporated magnetism to allow reversible bending deformation driven by magnets. However, such magneto‐responsive microarray surfaces suffer from highly restricted deformation range and poor control precision under magnetic field, restraining their droplet manipulation capability. Herein, a novel magneto‐responsive shutter (MRS) design composed of arrayed microblades connected to a frame is developed for on‐demand droplet manipulation. The microblades can perform two dynamical transformation operations, including reversible swing and rotation, and significantly, the transformation can be precisely controlled over a large rotation range with the highest rotation angle up to 3960°. Functionalized MRSs based on the above design, including Janus‐MRS, superhydrophobic MRS (SHP‐MRS) and lubricant infused slippery MRS (LIS‐MRS), can realize a wide range of droplet manipulations, ranging from switchable wettability, directional droplet bounce, droplet distribution, and droplet merging, to continuous droplet transport along either straight or curved paths. MRS provides a new paradigm of using swing/rotation topographic transformation to replace conventional bending deformation for highly efficient and on‐demand multimode droplet manipulation under magnetic actuation.

Published: October 2021

AbstractSouth Africa produces both marine and freshwater aquaculture species, with a combined production output of 5418 tons of food fish in 2015. Key aquaculture species reportedly cultured include four marine species – abalone, dusky kob, mussels and oysters and seven freshwater species – tilapia, trout, catfish, marron crayfish, carp, koi‐carp and ornamental species. The study aims to quantitatively assess the SWOT factors (Strengths, Weaknesses, Opportunities and Threats) of major aquaculture species of South Africa to determine their aquaculture development and market potential. Key food fish species – abalone, dusky kob, mussel, oyster, salmon, trout, tilapia, catfish and marron crayfish, were selected and subjected to qualitative and quantitative SWOT analyses by adapting the quantified SWOT analytical method coupled with the multi‐attribute decision‐making method MADM (SWOT‐MADM). Trout and tilapia are positioned in quadrant I, showing a combination of competitive strengths and market opportunities. Abalone, oyster and marron crayfish are situated in quadrant II; thus, they possess market opportunities but weak in competitive strengths as aquaculture species. Salmon and dusky kob are positioned in quadrant III; both species are weak in competitive strengths and faced with more threat factors rather than market opportunities. Mussel and catfish are in quadrant IV; both species thus have competitive strengths but are facing more threats than opportunities. Catfish recorded the highest competitive strengths due to internal assessment factors such as low FCR, ability to tolerate very high stocking density, rapid growth rate, high survival rate, hardiness and versatility of production systems and locations. Abalone and marron crayfish, on the other hand, both exhibited more market opportunities compared to other key aquaculture species due to external assessment factors like high pricing and good financial indicators. The study is expected to add to the existing body of knowledge and in guiding aquaculture industry stakeholders to make informed decisions with regards to the feasibility of aquaculture species in South Africa.

AbstractThis is a multicenter prospective observational study that included a large cohort (n = 397) of allogeneic (allo‐HSCT; (n = 311) and autologous (ASCT) hematopoietic stem cell transplant (n = 86) recipients who were monitored for antibody detection within 3–6 weeks after complete severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) vaccination from February 1, 2021, to July 20, 2021. Most patients (n = 387, 97.4%) received mRNA‐based vaccines. Most of the recipients (93%) were vaccinated more than 1 year after transplant. Detectable SARS‐CoV‐2‐reactive antibodies were observed in 242 (78%) of allo‐HSCT and in 73 (85%) of ASCT recipients. Multivariate analysis in allo‐HSCT recipients identified lymphopenia < 1 × 109/ml (odds ratio [OR] 0.33, 95% confidence interval [95% CI] 0.16–0.69, p = .003), active graft versus host disease (GvHD; OR 0.51, 95% CI 0.27–0.98, p = .04) and vaccination within the first year of transplant (OR 0.3, 95% CI 0.15–0.9, p = .04) associated with lower antibody detection whereas. In ASCT, non‐Hodgkin's lymphoma (NHL; OR 0.09, 95% CI 0.02–0.44, p = .003) and active corticosteroid therapy (OR 0.2, 95% CI 0.02–0.87, p = .03) were associated with lower detection rate. We report an encouraging rate of SARS‐CoV‐2‐reactive antibodies detection in these severe immunocompromised patients. Lymphopenia, GvHD, the timing of vaccine, and NHL and corticosteroids therapy should be considered in allo‐HSCT and ASCT, respectively, to identify candidates for SARS‐CoV‐2 antibodies monitoring.

Ring‐Opening Metathesis Polymerization of a Macrobicyclic Olefin Bearing a Sacrificial Silyloxide Bridge

Published: October 2021

AbstractRing‐opening metathesis polymerization (ROMP) has been regarded as a powerful tool for sequence‐controlled polymerization. However, the traditional entropy‐driven ROMP of macrocyclic olefins suffers from the lack of ring strain and poor regioselectivity, whereas the relay‐ring‐closing metathesis polymerization inevitably brings some unnecessary auxiliary structure into each monomeric unit. We developed a macrobicyclic olefin system bearing a sacrificial silyloxide bridge on the α,β′‐positions of the double bond as a new class of sequence‐defined monomer for regioselective ROMP. The monomeric sequence information is implanted in the macro‐ring, while the small ring, a 3‐substituted cyclooctene structure with substantial ring tension, can provide not only narrow polydispersity, but also high regio‐/stereospecificity. Besides, the silyloxide bridge can be sacrificially cleaved by desilylation and deoxygenation reactions to provide clean‐structured, non‐auxiliaried polymers.

Published: October 2021

AbstractThe local delivery of gaseous signaling molecules (GSMs) has shown promising therapeutic potential. However, although GSMs have a subtle interplay in physiological and pathological conditions, the co‐delivery of different GSMs for therapeutic purposes remains unexplored. Herein, we covalently graft a nitric oxide (NO)‐releasing N‐nitrosamine moiety onto the carbon monoxide (CO)‐releasing 3‐hydroxyflavone (3‐HF) antenna, resulting in the first NO/CO‐releasing donor. Under visible light irradiation, photo‐mediated co‐release of NO and CO reveals a superior antimicrobial effect toward Gram‐positive bacteria with a combination index of 0.053. The synergy of NO and CO hyperpolarizes and permeabilizes bacterial membranes, which, however, shows negligible hemolysis and no evident toxicity toward normal mammalian cells. Moreover, the co‐release of NO and CO can efficiently treat MRSA infection in a murine skin wound model, showing a better therapeutic capacity than vancomycin.
Stacked Reticular Frame Boosted Circularly Polarized Luminescence of Chiral Covalent Organic Frameworks

Published: October 2021

AbstractChiral covalent organic frameworks (COFs) with circularly polarized luminescence (CPL) are intriguing as advanced chiroptical materials but have not been reported to date. We constructed chiroptical COF materials with CPL activity through the convenient Knoevenagel condensation of formyl‐functionalized axially chiral linkers and C3‐symmetric 1,3,5‐benzenetriacetonitrile. Remarkably, the as‐prepared chiral COFs showed high absorption and luminescent dissymmetric factors up to 0.02 (gabs) and 0.04 (glum), respectively. In contrast, the branched chiral polymers from the same starting monomers were CPL silent. Structural and spectral characterization revealed that the reticular frame was indispensable for CPL generation via confined chirality transfer. Moreover, reticular stacking boosted the CPL performance significantly due to the interlayer restriction of frame. This work demonstrates the first example of a CPL‐active COF and provides insight into CPL generation through covalent reticular chemistry, which will play a constructive role in the future design of high‐performance CPL materials.
