Published: April 2019

Introdução: A linguagem de indexação é uma parte fundamental da política de indexação, tendo em vista seu papel mediador na representação e recuperação da informação. Para conhecer a realidade em catálogos online de bibliotecas universitárias realizou-se estudo analítico sobre linguagem na política de indexação de bibliotecas universitárias. Objetivo: O estudo analítico tem o objetivo de verificar o uso de linguagem de indexação pelos profissionais, qual(is) linguagem(ns) utilizam, a existência de manual de política de indexação e o uso de software de construção e manutenção disponível para o catalogador. Metodologia: Para isso, foi construído e aplicado questionário em amostra de bibliotecas universitárias da região sudeste do Brasil. Resultados: O questionário foi respondido por 60 bibliotecas com o seguinte perfil: 60% possui coleções especializadas de uma até quatro áreas de assunto, 73% das bibliotecas tem de 1 a 3 profissionais dedicados à indexação, 83% das bibliotecas integram uma rede ou sistema, 50% participam de catálogos coletivos. Com relação ao uso, verificou-se que 49 (89,1%) utilizam alguma linguagem de indexação, 25 (51%) utilizam uma linguagem de indexação, sendo 20 com linguagem própria sem uso de software específico para construção e manutenção, e 24 (49%) mais de uma linguagem. Entre as bibliotecas que utilizam linguagem de indexação, 19 bibliotecas adotam procedimentos quando não são encontrados termos na linguagem, 17 bibliotecas atualizam a linguagem por meio de interoperabilidade semântica. A formalização da política de indexação em documento é realizada por 58,3% e apenas 22% não descrevem a linguagem de indexação. Conclusões: O estudo analítico realizado com aplicação do questionário revela novos cenários no uso de linguagens de indexação em bibliotecas com avanços, problemas e lacunas que são verdadeiros desafios a serem enfrentados, em conjunto, pelos profissionais e pesquisadores.

Published: April 2019

O objetivo deste trabalho é mensurar o impacto de mudanças institucionais sobre a produção de açúcar no Brasil, entre 1980 e 2015. Foram consideradas três mudanças institucionais: a inovação do açúcar (tipo Very High Polarization); a desregulamentação setorial e; a queda dos subsídios europeus à produção desta commodity. A relevância deste trabalho está no fato destas mudanças serem analisadas empiricamente (teste de hipóteses, taxa de crescimento e modelo econométrico). O resultado do teste de hipóteses comprovou que a produção média de açúcar se alterou antes e depois de cada evento. As taxas de crescimento demonstraram que, após cada mudança, o ritmo de produção foi alterado, sobretudo para a região Centro-Sul e no estado de São Paulo. O modelo econométrico demonstrou que as mudanças institucionais alteraram a inclinação da curva de produção do açúcar. Comprova-se que a inovação do açúcar VHP foi a mudança institucional que mais impactou a produção brasileira.

Social identity and the use of ideological categorization in political evaluation
Authors: Haas Ingrid J. , Jones Christopher R. , Fazio Russell H.
Published: April 2019

In this research, we address a longstanding question concerning how individuals evaluate social and political issues. We focus on the role that political self-identification plays when individuals evaluate policy statements. In a laboratory setting, participants completed a task facilitation procedure, in which they made paired sets of judgments about a series of policy statements. Relative to a control task, ideological categorization of policy statements as liberal or conservative influenced the ease of evaluation. On experimental trials that began with ideological categorization, policy evaluations that were consistent with the participant’s own ideology were made more quickly than responses that were ideologically inconsistent and more quickly than responses following a control judgment. In three experiments, we show that this effect is stronger for individuals with more accessible ideological identification (Experiment 1) and more extreme ideological identification (Experiment 2), and that it holds when examining partisan instead of ideological identification (Experiment 3). The findings suggest that the use of ideological category information can facilitate and interfere with evaluative judgments of political issues, and that the use of such categories varies as a function of individual differences in the strength of political identification.

Published: April 2019

Most bones in mammals display a limited capacity for natural large-scale repair. The ribs are a notable exception, yet the source of their remarkable regenerative ability remains unknown. Here, we identify a Sox9-expressing periosteal subpopulation that orchestrates large-scale regeneration of murine rib bones. Deletion of the obligate Hedgehog co-receptor, Smoothened, in Sox9-expressing cells prior to injury results in a near-complete loss of callus formation and rib bone regeneration. In contrast to its role in development, Hedgehog signaling is dispensable for the proliferative expansion of callus cells in response to injury. Instead, Sox9-positive lineage cells require Hh signaling to stimulate neighboring cells to differentiate via an unknown signal into a skeletal cell type with dual chondrocyte/osteoblast properties. This type of callus cell may be critical for bridging large bone injuries. Thus despite contributing to only a subset of callus cells, Sox9-positive progenitors play a major role in orchestrating large-scale bone regeneration.

Authors: Hachi D. , Benhadda N. , Helifa B. , Lefkaier I. K. , Abdelhadi B.
Published: April 2019

In this paper, an iterative technique, employing the T formulation associated with the finite element method, based on Maxwell's equations and the Biot-savart law, is used for analyzing the density of eddy currents in composite carbon fiber reinforced polymer (CFRP) materials. For this purpose, a code has been developed for solving an electromagnetic 3D non-destructive evaluation problem. This latter permits the characterization of this CFRP and determinate of fibers orientation using the impedance variation which is implanted in polar diagram. Firstly, the obtained results are compared with those of the analytical model. This comparison reveals a high concordance which proves the validity of the proposed method. Secondly, three different applications are shown for illustrating the characterization of unidirectional, bidirectional and multidirectional piece using a rectangular coil plotted in normalized impedance diagram.
Upstream sequence-dependent suppression and AtxA-dependent activation of protective antigens inBacillus anthracis
Authors: Toyomane Kochi , Furuta Yoshikazu , Fujikura Daisuke , Higashi Hideaki
Published: April 2019

The anthrax toxin is a virulence factor produced by the bacteriumBacillus anthracis. Transcription of anthrax toxin genes is controlled by the transcription factor AtxA. Thus, AtxA is thought to be a key factor for the pathogenicity ofB. anthracis. Despite its important role inB. anthracisinfection, the molecular mechanism by which AtxA controls expression of anthrax toxin remains unclear. This study aimed to characterize the molecular mechanism of AtxA-mediated regulation of protective antigen (PA), a component of anthrax toxin encoded by thepagAgene. First, the interaction between the upstream region ofpagAand AtxA was evaluated in vivo by constructing a transcriptional fusion of the upstream region with an auxotrophic marker. The results showed that (i) the upstream region ofpagAsuppressed transcription of the downstream gene and (ii) AtxA recovered suppressed transcription. Second, in vitro analysis using a gel mobility shift assay was performed to evaluate binding specificity of the AtxA–DNA interaction. The result showed sequence-independent binding of AtxA to DNA. Taken together, our findings suggest that the expression of PA was suppressed by the upstream region ofpagAand that an interaction of AtxA and the upstream region releases the suppression.

Authors: Fontanella Rosane
Published: April 2019

Depois da revolução tecnológica e da globalização, muitas profissões tiveram um up e, como consequência, foram obrigadas a adaptar-se à nova realidade. Dentro desta nova realidade, o perfil do profissional de secretariado evoluiu e se desenvolveu numa trajetória de lutas e conquistas, mudando significativamente. Com a mudança também cresceram as responsabilidades e os desafios. Desempenhando funções meramente operacionais, o profissional de secretariado passou a pensar e atuar estrategicamente junto com seu(s) executivo(s), conhecendo objetivos, envolvendo-se em projetos e metas. Este trabalho mostra como o profissional de secretariado consegue executar e administrar a sua função ao assessorar executivos com tipos comportamentais tão diferentes. Sinaliza a postura que o profissional de secretariado precisa adotar frente a esses tipos comportamentais e como a utilização de elementos da Inteligência Emocional e da Inteligência Social pode ajudar a criar um ambiente amistoso onde todos possam conviver em harmonia.

Este artigo apresenta resultados parciais de um projeto de pesquisa, com enfoque interdisciplinar, realizado em parceria por professores dos cursos de Administração e Secretariado Executivo da Universidade Estadual do Centro Oeste do Paraná (UNICENTRO), no ano de 2011, o qual se propôs auxiliar, a partir da realidade local, na elaboração de um plano para captação de recursos destinado a ONG “X”, localizada na cidade de Guarapuava/PR, uma vez que desde o ano de 2006 houve uma redução dos recursos investidos pelos principais financiadores - Agências de Cooperação Internacional - nesta organização. Trata-se de uma pesquisa qualitativa com proposição de planos, que utilizou a pesquisa bibliográfica, documental e a observação participante seguida de reuniões com o dirigente e funcionários da ONG como principais técnicas de pesquisa. Percebeu-se que esta organização depende quase que integralmente dos recursos captados junto às fontes externas e, no entanto, não possui efetivamente ações planejadas de captação de recursos. Por sua vez, o estudo empírico demonstrou que há possibilidade de se ampliar as fontes e possibilidades de captação de recursos para esta ONG na região de Guarapuava desde que se tenha um projeto bem estruturado. Desta maneira, observou-se a relevância em se trabalhar interdisciplinarmente, visto que a área de assessoria permite um esforço coordenado de várias disciplinas em torno de um objetivo comum, que, neste estudo configura-se uma proposição na área de Responsabilidade Social.

Authors: Akume Joy N. , Ariahu Charles C. , Acham Israel O.
Published: April 2019

Garri is a popular, easy to prepare, storable and low cost staple food made from cassava roots, but lacks the right balance of nutrients. The aim of this study was to evaluate the effect of incorporating mango fruit mesocarp flour as a supplement on the functional, physicochemical and sensory properties of garri. Four blend ratios and codes of 100:0 (C100M0G), 90:10 (C90M10G), 80:20 (C80M20G) and 70:30 (C70M30G) were developed for cassava mash and mango fruit mesocarp flour respectively. The proximate composition, vitamin and elemental composition, functional properties and sensory attributes of the samples were analysed using standard methods. Results from this study revealed that increase in mango fruit mesocarp flour supplementation in the garri increased the protein (1.01 to 1.42%), fat (negligible increase), ash (0.47 to 1.28%), carbohydrate (82.99 to 87.15%), Vitamin A (3.00 to 160.66 µg/100g), Vitamin C (10.23 to 33.34 mg/100g), calcium (0.43 to 1.04%), potassium (0.07 to 0.28%), sodium (0.05 to 0.22%) contents as well as sensory attributes whose values ranged from 5.7 to 7.9 on a 9 point hedonic scale; while decreasing the moisture (12.60 to 7.85%) and crude fibre (2.93 to 2.30%) contents in addition to the bulk density (0.66 to 0.51 g/ml), water absorption capacity (2.11 to 1.30 g/g) and swelling capacity (1.09 to 0.78 g/g). Therefore, adding mango fruit mesocarp flour as supplement has the ability to enhance the macro- and micro-nutrient content, functional properties and sensory characteristics of garri. Sensory evaluation revealed that C70M30G was the most preferred blend formulation.

This study compared organic and chemical fertilizers on qualitative yield and essence content of peppermint. The experiment was carried out as Randomized Complete Design in Agricultural Farm Center, Sari, Iran, in 2013. The treatments were as control, vermicompost, composed sheep manure and basic chemical fertilizers at N60, P50, K60; N60, P80, K60; N90, P50, K80 and N90, P80, K80, and replicated four times. The results showed that all the measured characteristics were significantly (p<0.05) influenced by both organic and chemical fertilizers at the two harvest times. The values of the quantitative (wet and dry yield) and qualitative characteristics (essence content and essence yield) were also more at the first harvest than the second harvest. At the first harvest, the maximum value for dry and wet yield, and the maximum essence value and its yield were attained by using both sheep manure and chemical fertilizers at the rate of N90, P80, K80. The highest value for dry (96 kg ha-1) and wet (207 kg ha-1) yield, and yield (0.46 lit ha-1) and content of essence (0.48 g/100 g) were obtained with vermicompost. The values obtained for vermicompost and sheep manure were not significantly different. Application of sheep manure and vermicompost as organic fertilizer was recommended for production of peppermint. Whereas essence content and yield for first harvest were significantly higher than other treatments and control.

Authors: Gautam Manisha , Wamik Azmi Gautam Jamra, Nisha,
Published: April 2019

The current study was focused on factorial design based bench-scale production of collagenase by Pseudomonas sp. Chemical and fermentation conditions including medium components (carbon, nitrogen, and growth supplements) were optimized. The medium containing sucrose, tryptone and gelatin substrate was found to enhance the production of collagenase. The physical parameters (agitation speed and aeration rate) were also optimized. Moreover, the interactive effect of optimized physicochemical parameters using two levels of six factors (26) of factorial design was studied for the maximum collagenase production. Among 64 combinations, the 57th combination was shown maximum 1.43 U/mL collagenase activity. The bench-scale production of collagenase was achieved in a 6 L working volume laboratory fermenter. The bench-scale fermenter produced 2.3-fold enhanced collagenase activity at reduced cultivation time (14th h) in comparison to the shake flask (24th h). The lead combination can be used for the large scale collagenase production in industrial fermenters.

Published: April 2019

Aim: For vegetable oil produce in Nigeria to be competitive in the international market and suitable for downstream applications. The Microbiological and Physicochemical Characteristic of oils are amongst the most important properties that must be studied.

Study Design: The study is design to isolate and identify microorganisms involved in degradation of palm kernel and cashew nut oils and to investigate the physicochemical characteristics of the oil samples during storage.

Place and Duration of Study: The study was conducted between April and September, 2015 at the Microbiology Laboratory of the Federal University of Technology, Akure, Ondo State, Nigeria.

Methodology: Palm kernel and cashew nut seeds were purchased from Oja Oba, Akure, Ondo State. Palm kernel and cashew nut oils were extracted using n-hexane by Soxhlet extractor. The oil samples were stored at room temperature (25°C ± 1) for three months. Microorganisms were isolated from the oil and identified every two weeks of storage. The effect of storage on the physicochemical characteristics (saponification value, peroxide value, acid value and specific gravity) of the oil samples was determined every two weeks of storage.

Results: The microbial profile of the associated organisms consists of Bacillus licheniformis, Staphylococcus aureus, Articosporium inflate, Aspergillus flavus, A. saprophyticus and Penicllium notatum. All the physicochemical parameters determined were increasing with time except the moisture content. Saponification values (SV) obtained for the palm kernel oil samples is 300 mgKOH/g and cashew oil is 400 mgKOH/g while no significant change was observed in the specific gravity of both oils.

Conclusion: The microbial load of the oil sample was low and the physicochemical property is evidence that the oil can be useful in production of soap and cosmetics.

Published: April 2019

Onion thrips, Thrips tabaci (Thysanoptera: Thripidae) is a major insect pest constraining onion production in the Central Zone of Tigray. Therefore, field experiment was conducted at Axum Agricultural Research from November 2015 to April 2016 to manage onion thrips using multiple techniques. The experiment was laid out in a randomized complete block design (RCBD) with split plot arrangement and replicated three times. Onion varieties Bombay Red and Nasik Red were used as main plot treatments and intercropping onion with one or two other vegetables including, cabbage, carrot and lettuce, as subplot treatments. Treating onion with the insecticide lambda-cyhalothrin (Karate) 5% EC and untreated sole onion were included as standard and control checks. Results showed that intercropping onion with cabbage, onion with cabbage + carrot and onion with cabbage + lettuce significantly reduced T. tabaci population by 58.47, 63.81 and 50.51%, respectively at higher infestations. Similarly, intercropping onion with cabbage, onion with cabbage + carrot and onion with lettuce + carrot showed a better effect in reducing thrips damage severity by 23.37, 23.09 and 17.66%, respectively, at higher infestations. Predatory thrips were observed on onion intercrops except the Karate 5% EC treated check. The highest marketable onion yield (35.52 t/ha) was obtained from onion intercropped with carrot and lettuce, though not significantly different from the untreated check. The lowest (23.54 t/ha) was obtained from onion intercropped with cabbage + lettuce. However, onion intercropped with lettuce gave the highest gross income (307344 ETB/ha). The lowest gross income was recorded from the insecticide treated plot (194583 ETB/ha). The study clearly showed that intercropping onion with other vegetables reduced the number of onion thrips and their damage on onion in the central zone of Tigray and hence can form an integral component in the integrated management of thrips on onion.

The treatments were: i) combination of diammonium phosphate (97.5 kg/ha), urea (82.5 kg/ha) and municipal solid waste compost (10,000 kg/ha), ii)  combination of  diammonium phosphate (97.5 kg/ha),  urea  (82.5 kg/ha)  and farm yard manure  (10,000 kg/ha), iii) diammonium phosphate  (195k g/ha) and urea  (165 kg/ha), iv) farm yard manure (20,000 kg/ha), v) municipal solid waste compost (20,000 kg/ha), and vi) control. The findings of the research indicated that the combination of municipal solid waste compost and inorganic fertilizers resulted in the highest total tuber yield and total marketable yield, 18.2±0.7 ton/ha and 17.8±0.7 ton/ha, respectively, with 149% relative marketable yield advantage over control. Sole application of municipal solid waste compost was also resulted in significant (P=.05) potato yield increment compared to the control. It resulted in an increase of marketable potato tuber yield advantage of 52% over the control with total marketable yield of 10.9±0.9 ton/ha. Hence, combined use of municipal solid waste compost and inorganic fertilizers may be a promising option for poor potato farmers around the City of Addis Ababa.

Several scoring systems were developed for prognosis and outcome prediction in sepsis. This study aims to evaluate the urinary albumin/creatinine ratio (ACR) as a prognostic predictor in sepsis. The study included 50 adult septic patients in a prospective observational study. Study excluded patients with preexisting chronic kidney disease or diabetes mellitus. After clinical evaluation, urine spot samples were collected on admission and 24 h later for ACR1 and ACR2. Admission APACHE IV score and the highest recorded SOFA score of their daily estimation were considered. This study also evaluated the need for mechanical ventilation, inotropic or vasoactive support, renal replacement therapy (RRT), and in-hospital mortality. In a population with Mean±SD 51.4±16.3 (19-82) year old with 34 (68%) males, we found that the ACR2 is correlated with both APACHE IV and SOFA scores (P <0.001). ACR2 was higher in patients who needed mechanical ventilation and inotropic or vasoactive support [121(21-235) and 166.5(89-235) mg/g respectively] compared to [49(22-120) and 56.5(21-211) mg/g], P <0.001 in both. ΔACR, ACR2, increasing ACR and APACHE IV were predictors of mortality. The AUC for mortality prediction was largest for ΔACR (1), increasing ACR (0.985), ACR2 (0.963) then APACHE IV (0.90). ∆ACR and ACR2 of 91.5 mg/g and -22 was 88.2% & 100% sensitive and 90.9% & 100% specific respectively to predict mortality. We concluded that the urinary ACR might be used as a simple test for prognosis and mortality prediction in sepsis.

Today, customers are looking for benefits from the bank, better service, lower transaction fees, higher interest rates, a sign of prestige, new products access from different channels. This study evaluates the influence of CRM dimensions on bank performance. Zenith Bank Plc was selected through purposive method, while judgmental sampling technique was also used to select Head of Operation, Accountant, Auditor, and Branch Manager from its 35 branches in Lagos, Nigeria, totaling 140 respondents as a sample size for the study. Multiple regression analysis, Ordinary Least Square (OLS) method of estimation was employed to analyze the data. Results revealed that CRM dimensions (customer involvement, long-term relationship with customers, joint problem-solving and information sharing) jointly and independently influence bank performance measured by customer satisfaction, deposit mobilization and profit level. Subsequently, the study recommended that management of Nigerian banks should be actively involved in changes in organization in order to spread positive vision of CRM concept and to support organizational change.

Homocysteine (Hcy) is associated with nonalcoholic fatty liver disease (NAFLD). orphan nuclear receptor subfamily 4 group A member 1 (NR4A1) is involved in hepatic lipid metabolism. However, the potential role of NR4A1 in Hcy‐associated NAFLD remains elusive. We aimed to elucidate the regulation of NR4A1 and its significance in Hcy‐induced NAFLD. Hcy induced steatosis and elevated the expression of CD36 and FATP2 in HepG2 cells. Furthermore, Hcy enhanced p300 and decreased HDAC7 recruitment to the NR4A1 promoter, resulting in histone H3K27 hyperacetylation and NR4A1 upregulation. Moreover, NR4A1 depletion not only mimicked but also exaggerated the effects of Hcy on steatosis, whereas NR4A1 agonist Cytosporone B (CsnB) blocked Hcy‐induced steatosis. In hyperhomocysteinemia (HHcy) mice, CsnB attenuated HHcy‐induced hepatic steatosis. Thus, Hcy transiently and rapidly induces NR4A1 expression to reduce Hcy‐induced steatosis.

Increasing evidence indicates that immune system dysfunction affects anti‐N‐methyl‐D‐aspartate receptor (NMDAR) encephalitis. This study aims to investigate the relationship between adhesion molecules and the pathophysiology in anti‐NMDAR encephalitis. Soluble forms of Intercellular adhesion molecule‐1 (sICAM‐1), vascular adhesion molecule‐1 (sVCAM‐1), and L‐selectin (sL‐selectin), were measured in the CSF and serum of 26 participants with anti‐NMDAR encephalitis, 11 patients with schizophrenia and 22 patients with noninflammatory disorders. CSF levels of sICAM‐1, sVCAM‐1 and sL‐selectin were significantly elevated in the anti‐NMDAR encephalitis group. sVCAM‐1 levels were positively associated with modified Rankin scale score in anti‐NMDAR encephalitis patients at the onset and 3‐month follow‐up.

A synergic interface design is demonstrated for photostable inorganic mixed‐halide perovskite solar cells (PVSCs) by applying an amino‐functionalized polymer (PN4N) as cathode interlayer and a dopant‐free hole‐transporting polymer poly[5,5′‐bis(2‐butyloctyl)‐(2,2′‐bithiophene)‐4,4′‐dicarboxylate‐alt‐5,5′‐2,2′‐bithiophene] (PDCBT) as anode interlayer. First, the interfacial dipole formed at the cathode interface reduces the workfunction of SnO2, while PDCBT with deeper‐lying highest occupied molecular orbital (HOMO) level provides a better energy‐level matching at the anode, leading to a significant enhancement in open‐circuit voltage (Voc) of the PVSCs. Second, the PN4N layer can also tune the surface wetting property to promote the growth of high‐quality all‐inorganic perovskite films with larger grain size and higher crystallinity. Most importantly, both theoretical and experimental results reveal that PN4N and PDCBT can interact strongly with the perovskite crystal, which effectively passivates the electronic surface trap states and suppresses the photoinduced halide segregation of CsPbI2Br films. Therefore, the optimized CsPbI2Br PVSCs exhibit reduced interfacial recombination with efficiency over 16%, which is one of the highest efficiencies reported for all‐inorganic PVSCs. A high photostability with a less than 10% efficiency drop is demonstrated for the CsPbI2Br PVSCs with dual interfacial modifications under continuous 1 sun equivalent illumination for 400 h.

Materials with a temperature‐controlled reversible electrical transition between insulator and conductor are attracting huge attention due to their promising applications in many fields. However, most of them are intrinsically rigid and require complicated fabrication processes. Here, a highly stretchable (680% strain) liquid metal polymer composite as a reversible transitional insulator and conductor (TIC), which is accompanied with huge resistivity changes (more than 4 × 109 times) reversibly through a tuning temperature in a few seconds is introduced. When frozen, the insulated TIC becomes conductive and recovers after warming. Both the phase change of the liquid metal droplets and the rigidity change of the polymer contribute directly to transition between insulator and conductor. A simplified model is established to predict the expansion and connection of liquid metal droplets. Along with high stretchability, straightforward fabrication methods, rapid triggering time, large switching ratio, good repeatability, the TIC offers tremendous possibilities for numerous applications, like stretchable switches, semiconductors, temperature sensors, and resistive random‐access memory. Accordingly, a system that can display numbers and letters via converting alternative TIC temperature to a binary signal on a computer is conceived and demonstrated. The present discovery suggests a general strategy for fabricating and stimulating a stretchable transitional insulator and conductor based on liquid metal and allied polymers.

Published: April 2019

Self‐assembly guided by biological molecules is a promising approach for fabricating predesigned nanostructures. Protein is one such biomolecule possessing deterministic 3D crystal structure and peptide information, which acts as a good candidate for templating functional nanoparticles (fNPs). However, inadequate coordination efficacy during the establishment of interfacial interactions with fNPs makes it highly challenging to precisely fabricate designed nanostructures and functional materials. Here, a facile and robust strategy is reported for the hierarchical assembly of fNPs into ordered architectures, with unprecedentedly large sizes up to tens of micrometers, using a hollow cylinder‐shaped tobacco mosaic virus coat protein (TMV disk). The rational design of the site‐specific functional groups on the TMV disk not only demonstrates the powerful capability of directing various discrete fNP assemblies with high controllability but also assists in precise assembly of a TMV monolayer sheet structure for further organizing homogeneous and heterogeneous fNP periodic lattices by varying the types of fNPs. The high precision and adjustability of the pattern fashions of different fNPs unambiguously corroborate the validity of this innovative strategy, which provides a convenient route to design and assemble protein‐based hierarchical ordered architectures for use in nanophotonics and nanodevices.

Global oscillations in the brain synchronize neural populations and lead to dynamic binding between different regions. This functional connectivity reconfigures as needed for the architecture of the neural network, thereby transcending the limitations of its hardwired structure. Despite the fact that it underlies the versatility of biological computational systems, this concept is not captured in current neuromorphic device architectures. Herein, functional connectivity in an array of organic neuromorphic devices connected through an electrolyte is demonstrated. The output of these devices is shown to be synchronized by a global oscillatory input despite the fact that individual inputs are stochastic and independent. This temporal coupling is induced at a specific phase of the global oscillation in a way that is reminiscent of phase locking of neurons to brain oscillations. This demonstration provides a pathway toward new neuromorphic architectural paradigms, where dynamic binding transcends the limitations of structural connectivity, and could enable architectural concepts of hierarchical information flow.

Published: April 2019

An 88‐year‐old woman presented with acute airway obstruction caused by a large retrothyroid bleed following anterior neck trauma. Her airway was secured in the operating theatre with an awake nasal flexible optical bronchoscope tracheal intubation using an Intubating Laryngeal Mask Airway tracheal tube. Haemostasis was achieved following surgical ligation and the patient was transferred to the critical care unit. Postoperatively, a large leak around the tracheal tube was noted and a decision was made to change to an orotracheal tube with a subglottic drainage port. Our exchange technique required two experienced operators. The first operator used videolaryngoscopy with a hyperangulated blade to establish an optimal view of the larynx. The second operator placed an airway exchange catheter through the existing nasal tracheal tube to ensure airway control. The trachea was then intubated orally using a flexible optical bronchoscope observed under direct vision using the videolaryngoscope. The technique combined several simple and well‐documented approaches, but importantly, the airway remained secure and visible throughout the procedure.
