Authors: Oliveira Jossane Rodrigues de , Sabota Barbra 
Published: March 2021

<p align="justify">Neste artigo discutimos algumas concepções teóricas sobre língua e translinguagem buscando traçar uma relação com a interculturalidade considerando o cenário da educação linguística crítica. Nosso objetivo é, a partir de nosso local de fala, problematizar esses termos e compreender em que medida eles se relacionam em um ambiente que promova a educação linguística crítica propondo alguns exercícios de mobilização de saberes dentro desta perspectiva. Na realização dessas problematizações, inicialmente, apresentamos e discutimos separadamente os dois conceitos, relacionando-os à educação crítica de línguas. Em um segundo momento, apontamos as convergências entre os termos em busca de encaminhamentos para nossas praxiologias. Este é um estudo bibliográfico qualitativo interpretativista (ERICKSON, 1986), elaborado por meio de autores/as primordiais para a ampliação do entendimento desta interrelação. Referente às concepções de língua e translinguagem, trazemos para o debate autores/as tais como Canagarajah (2013), Garcia (2016; 2017), Kramsch (2019), Sequeira (2016), Munsberg e Silva (2018). Os estudos sobre cultura e interculturalidade (crítica) passam por Candau (2002), Kubota (2014), Risager (2006), Walsh (2009), entre outros/as. Finalizamos apontando exercícios de mobilização de saberes no intuito de contribuir para a percepção de que língua e cultura são indissociáveis para o processo de educação linguística crítica.</p>

Published: March 2021

AbstractThis paper studies the problem of parameter estimation for the multifrequency sine signals, which have multiple characteristic parameters such as the amplitudes, phases, and frequencies. It is noted that the signal output is nonlinear with respect to the phase and frequency parameters while it is linear with respect to the amplitude parameters. This feature inspires us to separate all of the characteristic parameters into a linear parameter set and a nonlinear parameter set, where the linear set is composed of the amplitude parameters and the nonlinear set is composed of the phase parameters and the frequency parameters. After the parameter separation, two identification submodels are constructed for optimizing the linear parameter set and the nonlinear parameter set. Then the nonlinear identification model becomes a linear identification submodel and a nonlinear identification submodel. Therefore, the nonlinear optimization for minimizing the objective function is converted into the combination of the quadratic optimization and nonlinear optimization. Based on the separable identification submodels, a recursive least squares subalgorithm and a recursive gradient subalgorithm are proposed for identifying the linear parameters and nonlinear parameters, respectively. Moreover, an interactive estimation algorithm is designed to remove the related parameter sets between the subalgorithms and a hierarchical identification method is presented by combining the subalgorithms. For the purpose of tracking the time‐varying, a forgetting factor is introduced to improve the convergence speed. The numerical examples are provided to qualify the performance of the proposed method based on some performance measures.

Published: March 2021

AbstractLike ready‐to‐wear clothing, medical devices come in a fixed set of sizes. While this may accommodate a large fraction of the patient population, others must either experience suboptimal results due to poor sizing or must do without the device. Although techniques have been proposed to fabricate patient‐specific devices in advance of a procedure, this process is expensive and time consuming. An alternative solution that provides every patient with a tailored fit is to create devices that can be customized to the patient's anatomy as they are delivered. This paper reports an in vivo molding process in which a soft flexible photocurable stent is delivered into the trachea or bronchi over a ultraviolet (UV)‐transparent balloon. The balloon is expanded such that the stent conforms to the varying cross‐sectional shape of the airways. UV light is then delivered through the balloon curing the stent into its expanded conformal shape. The potential of this method is demonstrated using phantom, ex vivo, and in vivo experiments. This approach can produce stents providing equivalent airway support to those made from standard materials while providing a customized fit.

Published: March 2021

AbstractDeveloping high‐capacity conversional cathode materials for aqueous Zn batteries is promising to improve their energy densities but challenging as well. In this work, three kinds of selenium–sulfur solid solutions and their composites (denoted as SeS14 @ 3D‐NPCF, SeS5.76 @ 3D‐NPCF, and SeS2.46 @ 3D‐NPCF) are proposed and systematically investigated. Due to the introduction of Se and its synergistic effect with S, their physical and electrochemical properties are manipulated; in particular, by optimizing the Se content in these composites, SeS5.76 @ 3D‐NPCF shows a capacity of 1222 mAh g−1 and flat plateau of 0.71 V at 0.2 A g−1, reaching an ultrahigh energy density of 867.6 Wh kg−1 (based on SeS5.76), superior rate capacity of 713 mAh g−1 at 5 A g−1, and stable cycling of 75% capacity retention after 500 cycles. In addition, the Zn storage kinetics is determined by the discharge process, during which SeS5.76 @ 3D‐NPCF is converted into ZnSe and ZnS. More importantly, theoretical calculations reveal that Se can tailor the electron density difference, band structure, and reaction energy of S, which increase its conductivity and reactivity to facilitate the electrochemical reaction with Zn. This work explores high performance conversional cathode materials for aqueous Zn metal batteries and presents an effective strategy to modify their intrinsic properties.

AbstractFullerenes are candidates for theranostic applications because of their high photodynamic activity and intrinsic multimodal imaging contrast. However, fullerenes suffer from low solubility in aqueous media, poor biocompatibility, cell toxicity, and a tendency to aggregate. C70@lysozyme is introduced herein as a novel bioconjugate that is harmless to a cellular environment, yet is also photoactive and has excellent optical and optoacoustic contrast for tracking cellular uptake and intracellular localization. The formation, water‐solubility, photoactivity, and unperturbed structure of C70@lysozyme are confirmed using UV‐visible and 2D 1H, 15N NMR spectroscopy. The excellent imaging contrast of C70@lysozyme in optoacoustic and third harmonic generation microscopy is exploited to monitor its uptake in HeLa cells and lysosomal trafficking. Last, the photoactivity of C70@lysozyme and its ability to initiate cell death by means of singlet oxygen (1O2) production upon exposure to low levels of white light irradiation is demonstrated. This study introduces C70@lysozyme and other fullerene‐protein conjugates as potential candidates for theranostic applications.

AbstractCytokine signaling is critical to a range of biological processes including cell development, tissue repair, aging, and immunity. In addition to acting as key signal mediators of the immune system, cytokines can also serve as potent immunotherapies with more than 20 recombinant products currently Food and Drug Administration (FDA)‐approved to treat conditions including hepatitis, multiple sclerosis, arthritis, and various cancers. Yet despite their biological importance and clinical utility, cytokine immunotherapies suffer from intrinsic challenges that limit their therapeutic potential including poor circulation, systemic toxicity, and low tissue‐ or cell‐specificity. In the past decade in particular, methods have been devised to engineer cytokines in order to overcome such challenges and here, the myriad strategies are reviewed that may be employed in order to improve the therapeutic potential of cytokine and chemokine immunotherapies with applications in cancer and autoimmune disease therapy, as well as tissue engineering and regenerative medicine. For clarity, these strategies are collected and presented as they vary across size scales, ranging from single amino acid substitutions, to larger protein‐polymer conjugates, nano/micrometer‐scale particles, and macroscale implants. Together, this work aims to provide readers with a timely view of the field of cytokine engineering with an emphasis on early‐stage therapeutic approaches.
Highway to Success—Developing Advanced Polymer Therapeutics

Published: March 2021

AbstractPolymer therapeutics are advancing as an important class of drugs. Polymers have already demonstrated their value in extending the half‐life of proteins. They show great potential as delivery systems for improving the therapeutic index of drugs, via biophysical targeting and more recently with more precision targeting. They are also important for intracellular delivery of nucleic acid based drugs. The same frameworks that have been successfully applied to improve the small molecule drug development can be adopted. This approach together with improved pathophysiological disease knowledge and critical developability considerations, imperative given the size and complexity of polymer therapeutics, provides a structured framework that should improve their clinical translation and exploit their functionality and potential. Progress in understanding the right target, gaining the right tissue and cell exposure, ensuring the right safety, selecting the right patient population is discussed. The right commercial considerations are outlined and the need for a multi‐disciplinary approach is emphasized. Crucial developability factors together with scientific and technical advancements to enable pharmaceutical development of a quality robust product are addressed. It is argued that by applying this structured approach to their design and development, polymer therapeutics will continue to grow and develop as important next generation medicines.

Published: March 2021

AbstractTissue spreading represents a key morphogenetic feature of embryonic development and regenerative medicine. However, how molecular signaling orchestrates the spreading dynamics and cell fate commitment of multicellular tissue remains poorly understood. Here, it is demonstrated that the dynamic counterbalance between RAC1–YAP and OB‐cadherin plays a key role in coordinating heterogeneous spreading dynamics with distinct cell fate patterning during collective spreading. The spatiotemporal evolution of individual stem cells in spheroids during collective spreading is mapped. Time‐lapse cell migratory trajectory analysis combined with in situ cellular biomechanics detection reveal heterogeneous patterns of collective spreading characteristics, where the cells at the periphery are faster, stiffer, and directional compared to those in the center of the spheroid. Single‐cell sequencing shows that the divergent spreading result in distinct cell fate patterning, where differentiation, proliferation, and metabolism are enhanced in peripheral cells. Molecular analysis demonstrates that the increased expression of RAC1–YAP rather than OB‐cadherin facilitated cell spreading and induced differentiation, and vice versa. The in vivo wound healing experiment confirms the functional role of RAC1–YAP signaling in tissue spreading. These findings shed light on the mechanism of tissue morphogenesis in the progression of development and provide a practical strategy for desirable regenerative therapies.

AbstractCereal/legume intercropping typically provides overyielding, particularly in low‐input agriculture. We examined the role of arbuscular mycorrhizal fungi (AMF) in responses to different P forms [Ca10(OH)2(PO4)6 (Ca‐P), sodium phytate (Na‐P), and KH2PO4 (K‐P)] in coix (Coix lacryma‐jobi L.)/faba bean (Vicia faba L.) intercropping systems. Shoot biomass of coix was significantly affected by P forms but not for faba bean. The Na‐P and K‐P treatments significantly enhanced shoot P concentration of coix with AMF inoculation conditions, however, Na‐P and K‐P treatments significantly enhanced the shoot P concentration of faba bean without AMF inoculation conditions. Monoculture faba bean had greater concentrations of malate and citrate and lower pH values than in intercropping, and than in monoculture coix. The growth of intercropped coix was promoted by the neighboring faba bean. We conclude that the difference utilized strategies in P forms of coix and faba bean, which improved intercropping productivity.

AbstractIntroductionHead injury is associated with significant morbidity and mortality. Long‐term associations of head injury with dementia in community‐based populations are less clear.MethodsProspective cohort study of 14,376 participants (mean age 54 years at baseline, 56% female, 27% Black, 24% with head injury) enrolled in the Atherosclerosis Risk in Communities (ARIC) Study. Head injury was defined using self‐report and International Classification of Diseases, Ninth/Tenth Revision (ICD‐9/10) codes. Dementia was defined using cognitive assessments, informant interviews, and ICD‐9/10 and death certificate codes.ResultsHead injury was associated with risk of dementia (hazard ratio [HR] = 1.44, 95% confidence interval [CI] = 1.3‐1.57), with evidence of dose‐response (1 head injury: HR = 1.25, 95% CI = 1.13‐1.39, 2+ head injuries: HR = 2.14, 95% CI = 1.86‐2.46). There was evidence for stronger associations among female participants (HR = 1.69, 95% CI = 1.51‐1.90) versus male participants (HR = 1.15, 95% CI = 1.00‐1.32), P‐for‐interaction < .001, and among White participants (HR = 1.55, 95% CI = 1.40‐1.72) versus Black participants (HR = 1.22, 95% CI = 1.02‐1.45), P‐for‐interaction = .008.DiscussionIn this community‐based cohort with 25‐year follow‐up, head injury was associated with increased dementia risk in a dose‐dependent manner, with stronger associations among female participants and White participants.
Enhancement of Radiative and Nonradiative Emission in Random Lasing Plasmonic Nanofibers
Authors: Singh Mahi R , Brassem Grant , Yastrebov Sergey 
Published: March 2021

AbstractA theory of light–matter interaction in plasmonic nanofibers is developed. When probe light propagates inside the nanofiber, it induces surface plasmon polariton (SPPs) and electric dipoles in metallic nanoparticles. The dipoles interact with each other via dipole–dipole interaction (DDI). The energy of photonic bound states in the presence of the SPP and DDI fields are calculated. It has been demonstrated that the number of bound states can be controlled by the strength of SPP and DDI couplings. The spontaneous decay rate for the quantum emitters have been calculated and it is found that decay rate is enhanced when the exciton energy is in resonance with the bound photon energy. Further, it is predicted that the spontaneous decay rate also enhances when the exciton and SPP energies are in resonance. Finally, the photoluminescence in nanofiber is calculated using the density matrix method. The authors' theory is compared with experiments and found a good agreement between theory and experiments. It has been demonstrated that the quenching of the photoluminescence intensity increases as the concentration of the MNPs increases. The findings of the paper can be used to fabricate random lasers and also for inventing new types of nanosensors and nanoswitches.

Published: March 2021

AbstractThe epoxy/silica nanocomposites containing a wide range of isopropyltri[di(octyl) phosphate] titanate coupling agent (KR‐12) modified nanosilica (m‐nanosilica) loading (0–7 wt%) cured with tetrabutyl titanate hardener were prepared. Their morphology, thermal stability, thermal expansion, and mechanical properties including hardness, abrasion resistance were investigated. The wetting ability of epoxy‐nanosilica systems on glass surface was assessed based on static contact angle. The obtained results showed that the contact angle of the nanocomposites containing m‐nanosilica is slightly changed as compared to the contact angle of pure epoxy resin and lower than that of the nanocomposite containing unmodified nanosilica. The data of dynamic mechanical analysis of the nanocomposites using different nanosilica content indicated that the presence of m‐nanosilica lowered the recovery energy of the nanocomposites to 41.62% as compared to neat epoxy. The limiting oxygen index (LOI) of the nanocomposites confirmed that the m‐nanosilica increased the flame retardance of epoxy matrix. When using 7 wt% of m‐nanosilca, the LOI value of the nanocomposite was 27.4 while this index of neat epoxy was 21.6. The scanning electron microscopic images of residual char combustion of the nanocompsites indicated a formation of nanosilica layer contributed to restrain combustion of the material.

Published: March 2021

Abstract2,5‐Furan dicarboxylic acid (FDCA) is a promising intermediate for producing polyethylene furan dicarboxylate, an alternative to polyethylene terephthalate that combines a significantly lower greenhouse gas footprint with better mechanical and gas barrier properties. This work presents a process design and techno‐economic evaluation for producing FDCA from non‐edible biomass via the oxidation of furfural to furoate salt, and subsequent carboxylation to furandicarboxylate salt. Major technical uncertainties are associated with the possible polymerization of furfural in the oxidation step and the state of salt phase in the carboxylation step. Based on the furfural market price of $1400/ton this process requires a minimum selling price of 2000 ± 500 $/ton FDCA. To compete with purified terephthalic acid (PTA), it requires a premium of 100% for better performance and sustainability, or a combination of much cheaper furfural and a much lower capital expenditures (CAPEX). © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
