Published: February 2022

Despite of the existence of previous knowledge on the relative growth of U. maracoani for a population of southeastern Brazilian coast, the aim of the study was described and compare the relative growth patterns and sexual maturity of this species from Formoso River mangrove, state of Pernambuco, northeast Brazil, with data from other locations and of congeneric species. The crabs were monthly sampled manually, with a capture effort by one person colleting for 30 minutes at the low tide from April 2009 to March 2010. Crabs of both sexes were measured with a caliper at following dimensions: carapace width (CW), carapace length (CL), cheliped propodus length (CPL), cheliped propodus height (CPH) and abdomen width (AW). Additionally, males were also measured at their gonopod length (GL). The determination of morphological maturity was based on the relationship between the CPL vs. CW for males and AW vs. CW for females, which were the relations that best evidenced the beginning of the morphological sexual maturity for U. maracoani. The relationships CPL vs. CW and AW vs. CW evidenced positive allometry for juveniles and adultâ€™s males and females. However, a negative allometry was observed in the relationship CL vs. CW and GL vs. CW for juveniles and adultâ€™s males, AW vs. CW for adultsâ€™ males and, CPH vs. CW for adultsâ€™ females. The growth pattern shown by the female abdomen probably is related to egg incubation and the excessive growth observed at the male cheliped is probably related to reproductive process, because this appendage is used at the courtship and intra or inter specific agonistic interactions with other males. The morphological sexual maturity of males was estimated at 15.8 mm CW (50% of males), with the smallest mature male measuring 17.34 mm, and the largest immature male 18.15 mm CW. Females reached morphological sexual maturity (50%) at 13.8 mm CW, with the smallest mature female at 15.43 mm CW and the largest immature female at 16.32 mm CW. The differential growth patterns between juvenile and adult phases, as well as the onset sexual maturity seem to have relationship with ontogenetic changes, which is mainly related to behavioral or reproductive traits. The growth pattern observed in the female's abdomen is probably related to hatching eggs while overgrowth shown in male cheliped should be related to reproductive processes, as this appendix is used in court and in specific interactions with other males.

O consumo de água em indústrias frigoríficas é elevado em função das práticas de higiene exigidas pelas autoridades sanitárias para a manutenção da qualidade dos produtos gerados nesses estabelecimentos. Estimar o consumo de água neste setor industrial permite o conhecimento das características da indústria e, consequentemente, a implantação de medidas de uso racional de água. O objetivo do estudo realizado foi estimar o consumo de água no processo produtivo de um frigorífico de bovinos, com abate médio de 550 cabeças/dia, localizado no estado de Rondônia, na região Norte do Brasil. Da mesma maneira, as fontes de abastecimento de água da indústria foram identificadas. O processo produtivo industrial foi descrito, bem como foram apresentados e quantificados os pontos de consumo de água dos setores que o compõem. O consumo de água foi estimado para os principais setores do processo produtivo, sendo realizada de maneira diferenciada para os setores providos e desprovidos de hidrômetros. Para os primeiros setores do processo produtivo (Abate, Bucharia, Triparia e Miúdos), realizou-se a estimativa do consumo de água por meio de dados sistematizados de leitura dos hidrômetros presentes nos setores referidos, analisando-os estatisticamente. Para os segundos setores (Transporte, Curral, Desossa, Expedição-Embarque de Congelados, Expedição-Embarque de Carne com Osso, Subprodutos e Expedição de Couro), a estimativa foi realizada por meio da quantificação de equipamentos que demandam água, como mangueiras e chuveiros, bem como outras características que influenciam no consumo de água nos setores em questão. O consumo de água total estimado para o processo produtivo do frigorífico foi de 14.253,34 m3/mês. O maior consumo de água ocorreu no Curral e o menor no setor Expedição de Couro. O consumo de água estimado por bovino abatido foi de 996,74 L/boi. Os resultados obtidos pretendem servir como referência e também como subsídio para a gestão racional e estratégica da água para indústrias frigoríficas localizadas na região Norte, assim como em outras regiões brasileiras.

Objetivo: La crisis generada por la pandemia Covid-19 ha puesto a prueba la capacidad de respuesta de la industria de la moda. Sin embargo, Loewe logró incrementar sus ventas y se convirtió en la única marca española que aumentó su valor de marca. Este crecimiento se debe en gran medida a la reinvención del uso de las herramientas de comunicación y el cambio de la orientación de su estrategia audiovisual. El objetivo principal de la investigación consiste en el estudio de las estrategias utilizadas por la marca en su esfuerzo por reinventarse durante la pandemia.
Diseño/metodología/enfoque: Se decidió recurrir a una metodología cuantitativa, de corte descriptivo para un primer acercamiento a la marca, y se completó con algunos ejemplos cualitativos para ilustrar las conclusiones. Seleccionamos las publicaciones en sus redes sociales entre enero de 2019 y enero de 2021 para hacer la investigación.
Resultados: Aun habiendo sufrido el impacto de la COVID-19, Loewe ha sabido aprovechar esta crisis para reinventarse y continuar en la vanguardia del sector de la moda, usando las redes sociales para innovar y co-crear la marca junto al usuario. Se concluye el artículo con la propuesta de un modelo teórico que ilustra el nuevo modo de creación de valor, para una marca de moda de lujo.
Limitaciones: La investigación se limita al análisis de los datos de un solo año, lo que no termina de ser suficiente para ver con precisión los resultados del proceso de reinvención iniciado por Jonathan Anderson. El estudio carece del análisis de la retroalimentación de los consumidores en escenarios digitales.
Originalidad/Contribución: El trabajo tiene una gran originalidad en la investigación de la estrategia de marca de moda en la crisis de Covid-19.

Published: February 2022

AbstractDespite breast cancer prevalence and widespread adoption of deep inspiration breath‐hold (DIBH) radiation techniques, few data exist on the error risks related to using surface‐guided (SG) DIBH during breast radiation therapy (RT). Due to the increasingly technical nature of these methods and being a paradigm shift from traditional breast setups/treatments, the associated risk for error is high. Failure modes and effects analysis (FMEA) has been used in identifying risky RT processes yet is time‐consuming to perform. A subset of RT staff and a hospital patient‐safety representative performed FMEA to study SG‐DIBH RT processes. After this group (cohort 1) analyzed these processes, additional scoring data were acquired from RT staff uninvolved in the original FMEA (cohort 2). Cohort 2 received abbreviated FMEA training while using the same process maps that cohort 1 had created, which was done with the goal of validating our results and exploring the feasibility of expedited FMEA training and efficient implementation elsewhere. An extensive review of the SG‐DIBH RT process revealed 57 failure modes in 16 distinct steps. Risks deemed to have the highest priority, large risk priority number (RPN), and severity were addressed with policy changes, checklists, and standardization; of these, most were linked with operator error via manual inputs and verification. Reproducibility results showed that 5% of the average RPN between cohorts 1 and 2 was statistically different. Unexpected associations were noted between RPN and RT staff role; 12% of the physicist and therapist average scores were statistically different. Different levels of FMEA training yielded similar scoring within one RT department, suggesting a time‐savings can be achieved with abbreviated training. Scores between professions, however, yielded significant differences suggesting the importance of involving staff across disciplines.
Finite‐time asynchronous dissipative filtering for Markovian jump systems with time‐varying delays and randomly occurred nonlinearity
Authors: Wang Yao , Guo Jun 
Published: February 2022

SummaryThe finite‐time dissipative filtering problem for time‐varying delayed Markovian jump systems with randomly occurred nonlinearity is addressed in this article. The modes of the desired filter are supposed to be asynchronous with the modes of the original system, which is more in line with the practical situation. The purpose of the problem under investigation is an asynchronous filter design which could make the error system finite‐time bounded as well as strictly dissipative. By constructing novel Lyapunov–Krasovskii functionals that covers the aforementioned two asynchronous modes and utilizing the theory of finite‐time analysis, some sufficient conditions are put forward to obtain the desired asynchronous filter by virtue of the linear matrix inequalities approach. A numerical example and a tunnel diode circuit are finally provided to demonstrate the effectiveness of our proposed method.

AbstractConductive cardiac patches have been proven to promote angiogenesis in infarcted myocardium; however, their conductive integrity, elasticity, and vascularization potential have not yet been optimized. The prevascularization of conductive elastic cardiac patches could be an effective strategy for building a substantial connection between the patch and the infarcted heart. Here, a coronary artery casting is introduced into a holey graphene oxide/polypyrrole‐incorporated polyhydroxyethyl methacrylate prefabricated gel to form a vascularized conductive elastic patch. The engineered patches are able to rebuild functional vascular anastomoses and provide strong electrical integration with infarcted hearts, resulting in effective myocardial infarction repair in vivo. RNA sequencing analyses further reveal that the conductive elastic patches under dynamic culture conditions upregulated cardiac muscle contraction‐ and ATP biosynthesis‐related mRNA expression in vitro. Together, this study demonstrates that the fabricated patches have versatile conductivity, elasticity, and vascularization properties, and could therefore be a promising candidate for heart repair.

Published: February 2022

AbstractSolution‐processable organic–inorganic hybrid perovskite materials have been applied to a variety of optoelectronic devices due to its long exciton lifetime and small binding energy. It has emerged as promising front‐runners for next‐generation non‐volatile flash photomemory devices. However, the effect of crystal orientation of perovskite on the performance of photomemory still has not fully developed. Herein, non‐volatile flash photomemory with quasi‐2D perovskite/polystyrene‐block‐poly(ethylene oxide) (PS‐b‐PEO) as photoactive floating‐gate and p‐type semiconductor poly(3‐hexylthiophene‐2,5‐diyl) (P3HT) as the chare‐transporting layer is successfully demonstrated. By adding phenylethylammonium bromide (PEABr) in formamidinium lead bromide perovskite (FAPbBr3), the crystal orientation of quasi‐2D perovskite is highly improved, which results in raised charge transfer efficiency from 76% to 90% compared to the pure FAPbBr3. Furthermore, ON/OFF current ratio of 104, low photo‐programming time of 5 ms under light intensity of 0.85 mW cm−2, charge transfer rate of 0.063 ns−1, and data storage capacity of over 7 bits (128 levels) in one cell can be achieved. In addition, the correlation between photo‐responsive current and photoluminescence (PL) is first examined by in operando PL measurement, which provides a new platform to explore the charge transfer process in photomemory.

AbstractLaminins (LNs) are key components in the extracellular matrix of neuronal tissues in the developing brain and neural stem cell niches. LN‐presenting hydrogels can provide a biologically relevant matrix for the 3D culture of neurons toward development of advanced tissue models and cell‐based therapies for the treatment of neurological disorders. Biologically derived hydrogels are rich in fragmented LN and are poorly defined concerning composition, which hampers clinical translation. Engineered hydrogels require elaborate and often cytotoxic chemistries for cross‐linking and LN conjugation and provide limited possibilities to tailor the properties of the materials. Here a modular hydrogel system for neural 3D cell cultures, based on hyaluronan and poly(ethylene glycol), that is cross‐linked and functionalized with human recombinant LN‐521 using bioorthogonal copper‐free click chemistry, is shown. Encapsulated human neuroblastoma cells demonstrate high viability and grow into spheroids. Long‐term neuroepithelial stem cells (lt‐NES) cultured in the hydrogels can undergo spontaneous differentiation to neural fate and demonstrate significantly higher viability than cells cultured without LN. The hydrogels further support the structural integrity of 3D bioprinted structures and maintain high viability of bioprinted and syringe extruded lt‐NES, which can facilitate biofabrication and development of cell‐based therapies.

Published: February 2022

AbstractThe past decades have witnessed an increasing interest in the exploration of room temperature gallium‐based liquid metal (LM) in the field of microfluidics, soft robotics, electrobiology, and biomedicine. Herein, this study for the first time reports the utilization of nanosized gallium–indium eutectic alloys (EGaIn) as a radiosensitizer for enhancing tumor radiotherapy. The sodium alginate (Alg) functionalized EGaIn nanoparticles (denoted as EGaIn@Alg NPs) are prepared via a simple one‐step synthesis method. The coating of Alg not only prevents the aggregation and oxidation of EGaIn NPs in an aqueous solution but also enables them low cytotoxicity, good biocompatibility, and in‐situ formation of gels in the Ca2+ enriched tumor physiological microenvironment. Due to the metallic nature and high density, EGaIn can increase the generation of reactive oxygen species under the irradiation of X‐ray, which can not only directly promote DNA damage and cell apoptosis, but also show an efficient tumor inhibition rate in vivo. Moreover, EGaIn@Alg NPs hold good performance as computed tomography (CT) and photoacoustic tomography (PAT) imaging contrast agents. This work provides an alternative nanotechnology strategy for tumor radiosensitization and also enlarges the biomedical application of gallium‐based LM.
Dual Self‐Healing Anticorrosion Coatings Based on Multibranched Waterborne Polyurethane and TiO2 Nanocapsule‐Loaded Graphene Oxide

Published: February 2022

AbstractThe study reports the successful fabrication of a novel dual self‐healing anticorrosion coating based on benzotriazole loaded TiO2 nanocapsule (BTC) modified graphene oxide sheets and the multibranched waterborne polyurethane (WPU). When corrosion occurs, the benzotriazole (BZT) in nanocapsules can be slowly released from the coating forming a passivation layer on the metal surface to isolate the corrosive mediums. The anticorrosion performance of coating is examined by performing electrochemical tests. As indicated from the results, after being immersed in 3.5 wt% NaCl for 7 d, the prepared coating shows excellent anticorrosion performance with inhibition efficiency of 99%. In addition, the φ in 104 Hz increases from 10° to 30°, and Log|Z|0.01Hz remains at nearly 4.5 with the immersing time extended to 30 d. Moreover, when the coating is physically damaged, the damaged coating can be self‐repaired by the reversible disulfide bonds in WPU and the releasing of the BZT simultaneously. Compared with other control anticorrosion coatings, the healed coating achieves significantly improved anticorrosion performance, and the damaged coating can still sustain the original anticorrosion performance after self‐healing. This study proposes a novel fabrication strategy for self‐healing materials, and it can contribute to the long‐term use of anticorrosion coatings.

Published: February 2022

AbstractIn this paper, an optically transparent low‐scattering metasurface combining polarization conversion, diffusion, and absorption mechanisms is proposed. Firstly, a polarization conversion absorbing meta‐atom is designed, and its reflection coefficient is optimized based on equivalent circuit theory and genetic algorithm. Then, by arranging the meta‐atom and its orthogonal structural meta‐atom according to the random coding sequence, the metasurface is constructed, realizing the design concept of co‐polarization absorption and cross‐polarization diffusion. The simulation results are in good agreement with the measured results and the Radar Cross Section (RCS) reduction of more than −10 and −25 dB can be realized in the co‐polarized and cross‐polarized directions in 3.3–12.3 GHz, respectively. Moreover, the amplitude and bandwidth of RCS reduction of the metasurface can be maintained well in the 0–40° oblique incidence range.
