O (NÃO) USO DAS PREPOSIÇÕES DATIVAS E A RELEXIFICAÇÃO DE PARA NO PORTUGUÊS AFRO-BRASILEIRO
Authors: Barros Isis Juliana Figueiredo de , Figueiredo Maria Cristina 
Published: June 2021

<p>O artigo busca apresentar os principais resultados da análise sociolinguística a respeito da variação no uso das preposições dativas <em>a</em> e <em>para</em> em comunidades afro-brasileiras (Helvécia, Sapé, Rio de Contas e Cinzento), levando-se em conta alguns contextos sintático-semânticos e sociais. A metodologia da descrição e análise dos dados obtidos orientou-se pela abordagem laboviana, de forma a obter resultados com base em levantamento estatístico. O resultado da análise da amostra indica que os contextos de realização do dativo preposicionado por <em>para</em> nem sempre coincidem com o dativo sem preposição ou o dativo preposicionado por <em>a</em>. Argumenta-se que o surgimento da preposição <em>para</em> no contexto de dativos em verbos bitransitivos dinâmicos teria sofrido um processo de relexificação, como resultado da influência das línguas de substrato banto durante o período de contato intenso entre línguas que caracteriza a formação sócio-histórica dessas comunidades.</p>
COVID-19 E SUAS METÁFORAS: “ROTEIRO” OU “RODÍZIO”?

Published: June 2021

O presente estudo cognitivo de índole qualitativa, ancorado na teoria da metáfora conceptual (LAKOFF; JOHNSON, 1980; GIBBS, 2017), assume como objetivo identificar os domínios-fonte de um leque de metáforas conceptuais usadas para representar a COVID-19, no contexto do discurso político. O facto de se tratar de doença infeciosa até agora desconhecida, com elevado risco de contágio e alguma taxa de mortalidade, promove a necessidade de a balizar semanticamente por via de figurações metafóricas e metonímias, tendo em vista a compreensão possível do fenómeno pandémico pelos cidadãos. A presente investigação visa traçar uma cronologia das metáforas de COVID-19 veiculadas pelos líderes políticos portugueses e pelo primeiro-ministro inglês, ao longo da vigência da pandemia, tomando como ponto de partida as imagens metafóricas de GUERRA. Coloca-se como questão de fundo se a evolução pandémica é acompanhada por uma sucessividade de figurações metafóricas dos líderes políticos, numa estratégia discursiva de “roteiro”, ou se o discurso político incide recorrentemente sobre as metáforas de GUERRA, numa estratégia discursiva de “rodízio”. Dado que se comprovou que os líderes políticos em questão enveredam pela estratégia discursiva de “roteiro”, o nosso foco incide sobre as metáforas culturalmente marcadas (HIDALGO-DOWNING; KRALJEVIC-MUJIC, 2009).

ObjectiveTo standardize and assess the reliability of ultrasonographic assessment of inflammatory and structural lesions in patients with hand osteoarthritis (OA).MethodsThe Outcome Measures in Rheumatology Ultrasound Working Group selected synovial hypertrophy (SH), joint effusion (JE), and power Doppler (PD) signals as the main inflammatory lesions in hand OA, and suggested osteophytes in the scapho‐trapezio‐trapezoid (STT) and cartilage defects in the proximal interphalangeal (PIP) joints as novel additions to previous structural scoring systems. A complementary imaging atlas provided detailed examples of the scores. A reliability exercise of static images was performed for the inflammatory features, followed by a patient‐based exercise with 6 sonographers testing inflammatory and structural features in 12 hand OA patients. We used Cohen's kappa for intrareader and Light's kappa for interreader reliability for all features except PD, in which prevalence‐adjusted bias‐adjusted kappa (PABAK) was applied. Percentage agreement was also assessed.ResultsThe web‐based reliability exercise demonstrated substantial intra‐ and interreader reliability for all inflammatory features (κ > 0.64). In the patient‐based exercise, intra‐ and interreader reliability, respectively, varied: SH κ = 0.73 and 0.45; JE κ = 0.70 and 0.55; PD PABAK = 0.90 and 0.88; PIP joint cartilage κ = 0.56 and 0.45; and STT osteophytes κ = 0.62 and 0.36. Percentage close agreement was high for all features (>85%).ConclusionWith ultrasound, substantial to excellent intrareader reliability was found for inflammatory features of hand OA. Interreader reliability was moderate, but overall high close agreement between readers suggests that better reliability is achievable after further training. Assessment of osteophytes in the STT joint and cartilage in the PIP joints achieved less reliability and the latter is not endorsed.

Published: June 2021

AbstractA useful direction to solve the energy problem is the effective repeated use of biomaterial for mechanical energy collection and sensing applications. Here, a feather‐based single‐electrode triboelectric nanogenerator (F‐STENG) by only sputtering copper atoms on the feathers are presented. The feather of F‐STENG, as a natural material, has environmental friendliness, which is different from the polymer materials of other triboelectric nanogenerators. F‐STENG has super durability due to its feather structure self‐healing property. The device has a high output voltage of 90 V and an output current of 3.5 µA. After breaking and self‐healing lots of times, the output performance is also 80% of the original. F‐STENG has a high sensitivity to temperature, humidity, and wind speed, and the sensitivity is 0.50 V °C−1, ‐0.98 V RH−1, and 1.67 μA m−1 s−1. The output power of F‐STENG is 0.62 mW g−1, which can realize global positioning and photographing to solve the module energy consumption problem. F‐STENG provides an effective way for the application of self‐powered sensors and equipment in military, industrial, transportation, and daily life.

AbstractDisruption of vulnerable atherosclerotic plaques often leads to myocardial infarction and stroke, the leading causes of morbidity and mortality in the United States. A diagnostic method that detects early‐stage high‐risk atherosclerotic plaques could prevent these sequelae. The abundant immune cells in the arterial wall, especially inflammatory Ly‐6Chi monocytes and foamy macrophages, are indicative of plaque inflammation, and may be associated with plaque vulnerability. Hence, a new method is sought to develop that specifically targets these immune cells to offer clinically relevant diagnostic information about cardiovascular disease. Ultraselective nanoparticle targeting of Ly‐6Chi monocytes and foamy macrophages and clinically‐viable photoacoustic imaging (PAI) are combined in order to precisely and specifically image inflamed plaques ex vivo in a mouse model that mimics human vulnerable plaques histopathologically. Within the plaques, high‐dimensional single‐cell flow cytometry (13‐parameter) shows that the nanoparticles are almost‐exclusively taken up by the Ly‐6Chi monocytes and foamy macrophages that heavily infiltrate plaques. PAI identifies inflamed atherosclerotic plaques that display ≈6‐fold greater signal compared to controls (P < 0.001) 6 h after intravenous injection of ultraselective carbon nanotubes, with in vivo corroboration via optical imaging. This highly‐selective strategy may provide a targeted, noninvasive imaging strategy to accurately identify and diagnose inflamed atherosclerotic lesions.
Long‐Term Super‐Amphiphilic Shaped‐Fiber with Multi‐Scale Grooved Structures: Toward Spontaneous Self‐Cleaning

Published: June 2021

AbstractDespite long‐term exposure to the ambient environment, fabrics made of bamboo fibers enable spontaneous self‐cleaning of oil contaminants without using any surfactant. Here, it is revealed that the long‐term stable super‐amphiphilicity of bamboo fibers is responsible for self‐cleaning behavior. Liquids of both water and oil are liable to super‐spread on bamboo fibers, driven by multi‐scaled capillary forces imparted by the unique shaped fibrous structures with multi‐scale hierarchical ridges/grooves. Based on the minimization of free energy, the pre‐wetted oils can be easily removed away by forming the water film, reaching the spontaneous self‐cleaning. Notably, the super‐amphiphilicity induced by the structure shows better long‐term stability compared with that endowed by chemical modification. It is demonstrated that the bio‐inspired artificial counterpart also exhibits excellent self‐cleaning property, which inspires innovative self‐cleaning textures.

AbstractAll‐inorganic CsPbI2Br perovskite has attracted great attention as an absorber for perovskite solar cells (PSCs) due to its excellent thermal and light resistance. However, its device performance is restricted by the large energy level offset between CsPbI2Br and the most commonly used hole‐transporting layer (HTL). Herein, multicarbazolyl‐substituted benzonitrile (4t‐5CzBn) is inserted into the interface between CsPbI2Br and HTL to form a uniform stepped (0.24 eV) interfacial energy level structure, which reduces the energy loss and boosts the hole extraction of CsPbI2Br PSCs. The incorporation of 4t‐5CzBn induces the increase in open‐circuit voltage and fill factor from 1.256 V and 74.5% to 1.335 V and 82.3%, respectively. The optimized device achieves a power conversion efficiency of 17.34%, which is among the highest reported values of CsPbI2Br PSCs. Besides the energy level tuning effect, the tert‐butyl groups in 4t‐5CzBn improve the moisture‐resistance of CsPbI2Br PSCs. The unencapsulated device maintains over 75% of its initial efficiency after 700 h storage in air. These results demonstrate that the rational tuned energy level step benefits the performance improvement of CsPbI2Br PSCs.
Interlayer Structure Engineering of MXene‐Based Capacitor‐Type Electrode for Hybrid Micro‐Supercapacitor toward Battery‐Level Energy Density
Authors: Cheng Wenxiang , Fu Jimin , Hu Haibo , Ho Derek 
Published: June 2021

AbstractMicro‐supercapacitors are notorious for their low energy densities compared to micro‐batteries. While MXenes have been identified as promising capacitor‐type electrode materials for alternative zinc‐ion hybrid micro‐supercapacitors (ZHMSCs) with higher energy density, their tightly spaced layered structure renders multivalent zinc‐ions with large radii intercalation inefficient. Herein, through insertion of 1D core‐shell conductive BC@PPy nanofibers between MXene nanosheets, an interlayer structure engineering technique for MXene/BC@PPy capacitor‐type electrodes towards ZHMSCs is presented. Owing to simultaneously achieving two objectives: (i) widening the interlayer space and (ii) providing conductive connections between the loose MXene layers, enabled by the conductive BC@PPy nanospacer, the approach effectively enhances both ion and electron transport within the layered MXene structure, significantly increasing the areal capacitance of the MXene/BC@PPy film electrode to 388 mF cm−2, which is a 10‐fold improvement from the pure MXene film electrode. Pairing with CNTs/MnO2 battery‐type electrodes, the obtained ZHMSCs exhibit an areal energy density up to 145.4 μWh cm−2 with an outstanding 95.8% capacity retention after 25000 cycles, which is the highest among recently reported MXene‐based MSCs and approaches the level of micro‐batteries. The interlayer structure engineering demonstrated in the MXene‐based capacitor‐type electrode provides a rational means to achieve battery‐levelenergy density in the ZHMSCs.

Published: June 2021

AbstractThe relationship between mechanical stress states and interfacial electrochemical thermodynamics of Li metal/Li6.5La3Zr1.5Ta0.5O12 and Na metal/Na‐β”‐Al2O3 systems are examined in two experimental configurations with an applied uniaxial load; the solid electrolytes are pellets and the metal electrodes high‐aspect‐ratio electrodes. The experimental results demonstrate that 1) the change in equilibrium potential at the metal/electrolyte interface, when stress is applied to the metal electrode, is linearly proportional to the molar volume of the metal electrode, and 2) the mechanical stress in the electrolyte has a negligible effect on the equilibrium potential for an experimental setup in which the electrolyte is stressed and the electrode is left unstressed. Solid mechanics modeling of a metal electrode on a solid electrolyte pellet indicates that pressure and normal stress are within ≈0.5 MPa of each other for the high aspect ratio (≈1:100 thickness:diameter in our study) Li metal electrodes under loads that exceed yield conditions. This work should aid in advancing the quantitative understanding of alkali metal dendrite formation within incipient cracks and their subsequent growth, and pore formation upon stripping, both situations where properly accounting for the impact of mechanical state on the equilibrium potential is of critical importance for calculating the current distribution.

AbstractIntroductionThe 2017 European Union‐North American Clinical Trials in Alzheimer's Disease Task Force recommended development of clinician‐rated primary outcome measures for Alzheimer's disease (AD) agitation trials, incorporating International Psychogeriatric Association (IPA) criteria.MethodsIn a modified Delphi process, Cohen‐Mansfield Agitation Inventory (CMAI) and Neuropsychiatric Inventory‐Clinician (NPI‐C) items were mapped to IPA agitation domains generating novel instruments, CMAI‐IPA and NPI‐C‐IPA. Validation in the Agitation and Aggression AD Cohort (A3C) assessed minimal clinically important differences (MCIDs), change sensitivity, and predictive validity.ResultsMCID was –17 (odds ratio [OR] = 14.9, 95% confidence interval [CI] = 6.8–32.6) for CMAI; –5 (OR = 9.3, 95% CI = 4.0–21.2) for CMAI‐IPA; –3 (OR = 11.9, 95% CI = 4.1–34.8) for NPI‐C‐A+A; and –5 (OR = 7.8, 95% CI = 3.4–17.9) for NPI‐C‐IPA at 3 months. Areas under the curve suggested no scale better predicted global clinician ratings. Sensitivity to change for all measures was high.ConclusionInternal consistency and reliability analyses demonstrated better accuracy for the NPI‐C‐IPA than for the CMAI‐IPA and can be used for agitation clinical trial inclusion, and for response to intervention.
Error‐Insensitive 3D Entanglement Gate with Optimal Control of Geometric Evolution
Authors: Niu Wei , Wu Jin‐Lei , Wang Pan , Ji Xin 
Published: June 2021

AbstractBy using the counterdiabatic driving method, two‐atom 3D entanglement gates are constructed rapidly based on adiabatic geometric quantum computation (AGQC). The added counterdiabatic Hamiltonian does not introduce additional unaccessible ground‐state coupling, and the shapes and phases of the initial adiabatic classical‐field pulse only need to be modified. By using the optimal control technology, the effect of the control errors of Rabi frequency or detuning is suppressed effectively. Quite specially, with an appropriate choice of optimized parameters, the authors' scheme could be insensitive to these two kinds of errors simultaneously. By combining AGQC with optimal control, the scheme could offer a promising means for constructing fast and robust high‐dimensional quantum entanglement gate.
Investigating the impact of emotions on perceiving serendipitous information encountering

Published: June 2021

AbstractDespite the potential importance of emotional aspects in information seeking, there is a lack of adequate attention to emotions' role in facilitating serendipitous information encountering. This paper contributes to this research gap by investigating the role of emotions during the process of perceiving and experiencing serendipitous information encountering in a controlled laboratory setting. The results show that applying a sketch game can stimulate participants' emotions. Our findings indicate that participants are more likely to experience serendipitous information encountering under the influence of positive emotions. This study contributes to an understanding of the relationship between emotions and the perception of serendipitous information encountering. The implications of the possibilities of facilitating positive emotions to induce serendipitous information encountering are discussed.
If we Ask, Will they Tell? (and Then, What?): Screening for Sexual Violence against Children in Kenya
Authors: Undie Chi‐Chi , Mak'anyengo Margaret 
Published: June 2021

This study assesses the feasibility of using a screening tool to proactively identify child survivors of sexual violence in Kenyan primary school and health facility settings, and to refer such survivors to care. A mixed‐methods design was employed, involving quantitative screening tool data, as well as service data from 497 girls and boys in two primary schools (in standards six to eight) and one hospital site (11–17‐year‐olds) and qualitative data (in the form of field notes) generated during the screening process. Results point to the feasibility of this screening intervention, as evidenced by the proportion of children in the school and health facility sites combined: 97 per cent were willing to be screened for sexual violence, 45 per cent disclosed lifetime sexual violence and 75 per cent received care subsequent to disclosing lifetime experiences of sexual violence. Further, the qualitative results ‘give voice’ to child survivors and their parents, demonstrating the acceptability of, and demand for, the intervention among these populations. Findings from this study suggest that screening for sexual violence against children is feasible in both school and health facility settings. Such screening also holds potential for expanding child survivors' access to care.‘Assesses the feasibility of using a screening tool to proactively identify child survivors of sexual violence in Kenyan primary school and health facility settings’Key Practitioner Messages

Chiral Perylene Bisimide Dyes by Interlocked Arene Substituents in the Bay Area
Authors: Renner Rebecca , Mahlmeister Bernhard , Anhalt Olga , Stolte Matthias , Würthner Frank 
Published: June 2021

AbstractA series of perylene bisimide (PBI) dyes bearing various aryl substituents in 1,6,7,12 bay positions has been synthesized by Suzuki cross‐coupling reaction. These molecules exhibit an exceptionally large and conformationally fixed twist angle of the PBI π‐core due to the high steric congestion imparted by the aryl substituents in bay positions. Single crystal X‐ray analyses of phenyl‐, naphthyl‐ and pyrenyl‐functionalized PBIs reveal interlocked π‐π‐stacking motifs, leading to conformational chirality and the possibility for the isolation of enantiopure atropoisomers by semipreparative HPLC. The interlocked arrangement endows these molecules with substantial racemization barriers of about 120 kJ mol−1 for the tetraphenyl‐ and tetra‐2‐naphthyl‐substituted derivatives, which is among the highest racemization barriers for axially chiral PBIs. Variable temperature NMR studies reveal the presence of a multitude of up to fourteen conformational isomers in solution that are interconverted via smaller activation barriers of about 65 kJ mol−1. The redox and optical properties of these core‐twisted PBIs have been characterized by cyclic voltammetry, UV/Vis/NIR and fluorescence spectroscopy and their respective atropo‐enantiomers were further characterized by circular dichroism (CD) and circular polarized luminescence (CPL) spectroscopy.
The effect of hydrogen bonding on the copolymerization kinetics of 2‐methoxyethyl acrylate with 2‐hydroxyethyl methacrylate in alcohol and aqueous solutions
Authors: Agboluaje Maryam , Hutchinson Robin A. 
Published: June 2021

AbstractThe influence of alcohol and alcohol/water solutions on the radical copolymerization kinetics of 2‐hydroxyethyl methacrylate (HEMA) with 2‐methoxyethyl acrylate (MEA) is studied using pulsed‐laser‐polymerization coupled with size exclusion chromatography. It is found that MEA incorporation into the copolymer is increased in butanol, methanol (MeOH), and MeOH/H2O solutions relative to the bulk system. Copolymer composition can be represented for solvent levels ≥50 vol.% by a single pair of reactivity ratios ( = 2.39 ± 0.16, = 0.28 ± 0.02) that differ from those in bulk ( = 3.14 ± 0.44, = 0.27 ± 0.04). MeOH as solvent slightly reduces the propagation rate coefficient of HEMA compared to the bulk system, in contrast to the increase in the MEA value. Thus, the value of is higher in MeOH for MEA‐rich systems compared to bulk, with the effect of the solvent reduced as the HEMA content in the comonomer mixture is increased. Adding water as cosolvent significantly increases values for both monomers, with in MeOH/H2O higher than bulk values over the complete composition range. Furthermore, for 50% monomer in the solvent systems studied can be represented by the implicit penultimate unit model using a single pair of radical reactivity ratios. It is concluded that the strongest influence of hydrogen‐bonding solvents compared to bulk is on the homopropagation values, rather than on copolymerization parameters, and that the difference in relative reactivity of non‐functional and functional monomers in bulk and aqueous solution should be accounted for when studying emulsion copolymerization.
