Published: August 2019

Coherent quantum optics, where the phase of a photon is not scrambled as it interacts with an emitter, lies at the heart of many quantum optical effects and emerging technologies. Solid-state emitters coupled to nanophotonic waveguides are a promising platform for quantum devices, as this element can be integrated into complex photonic chips. Yet, preserving the full coherence properties of the coupled emitter-waveguide system is challenging because of the complex and dynamic electromagnetic landscape found in the solid state. Here, we review progress toward coherent light-matter interactions with solid-state quantum emitters coupled to nanophotonic waveguides. We first lay down the theoretical foundation for coherent and nonlinear light-matter interactions of a two-level system in a quasi-one-dimensional system, and then benchmark experimental realizations. We discuss higher order nonlinearities that arise as a result of the addition of photons of different frequencies, more complex energy level schemes of the emitters, and the coupling of multiple emitters via a shared photonic mode. Throughout, we highlight protocols for applications and novel effects that are based on these coherent interactions, the steps taken toward their realization, and the challenges that remain to be overcome.
Thinking out loud: A discourse analysis of ‘thinking’ during talk radio interactions
Authors: Horowitz Ava D. , Kilby Laura
Published: August 2019

Early work in discursive psychology highlighted the rhetorical strength of devices that serve to establish matters as objective facts. More recently, there has been increasing interest within this discipline concerning mental state invocations (e.g. imagining; knowing; intending), which typically convey speaker subjectivity. Elsewhere, linguists have examined the social business enabled by speakers’ deployment of cognitive verbs, a prime example of which deals with overt references to thinking. The current article sets out to extend the work on thinking by synthesizing research from discursive psychology, linguistics, and conversation analysis in order to undertake an integrated analysis of thinking. In our examination of a UK talk radio corpus, comprising data from 11 talk radio shows, we demonstrate three discursive functions of deploying a thinking device: setting an intersubjective agenda; doing opinion; and managing ‘facts’. An integrated approach allows us to examine the rhetorical strength of these subjectivizing maneuvers, and contribute to the existing body of work concerning the discursive deployment of thinking and mental state terms.
Effect of Irreversible Electrochemical Reaction on Diffusion and Diffusion-Induced Stresses in Spherical Composition–Gradient Electrodes
Authors: Zhang Kai , Zheng Bailin
Published: August 2019

Composition–gradient electrodes have been proved to have excellent electrochemical performances. The effect of irreversible electrochemical reaction on diffusion and diffusion-induced stresses in such electrodes is investigated. The diffusion equation and mechanical equation considering the electrochemical reaction and the heterogeneous factors are derived, and the distributions of lithium (Li) concentration and stresses in a spherical electrode are obtained under potentiostatic charging. The results indicate that the electrochemical reaction will slow down the diffusion process and enhance the stresses of the electrode. However, the heterogeneous factors of the electrochemical reaction could provide a positive effect on the stresses, which means that the heterogeneous factor is conducive to avoid capacity fading of the battery. The results suggest that the composition–gradient electrodes could be designed to have a decreasing transition form of forward reaction rate and an increasing transition form of the difference of atomic volume between reactants and the reaction product.

Waldman, HS, Smith, JW, Lamberth, J, Fountain, BJ, and McAllister, MJ. A 28-day carbohydrate-restricted diet improves markers of cardiometabolic health and performance in professional firefighters. J Strength Cond Res 33(12): 3284–3294, 2019—We investigated the effects of a 4-week ad-libitum, nonketogenic, carbohydrate-restricted (<25% of calories) diet (CRD) on cardiometabolic and performance markers in firefighters (FF). Subjects (n = 15) completed 9 sessions (trials 1–3 [familiarization], trials 4–6 [baseline], and trials 7–9 [post-CRD]). Following habitual western diet, anthropometric measures were assessed, glucose tolerance measured, and then completed a graded cycling test, maximal Wingate test, and conducted their FF physical performance assessment (FPPA) to measure performance while metabolic variables and perceptual responses were recorded. Subjects then adhered to a CRD for a 4-week duration and returned for repeat testing. Body fat as measured by BodPod, and 7-site skinfold thickness decreased (p < 0.01), and a decrease was observed in blood pressure (BP) (p < 0.01; ∼5 mm Hg) after CRD. There were no differences found for glucose tolerance, but an increase was found for fat oxidation rates (p < 0.01; ∼0.07 g·min−1) and a decrease in carbohydrate oxidation rates across a range of intensities (p < 0.01; ∼0.24 g·min−1). Finally, the 2.41-km run and pull-up performance during the FPPA improved (p < 0.01; ∼41 second and 3 repetitions, respectively) and with no differences observed between treatments regarding the Wingate test. To date, this is the first CRD implemented with FF and resulted in decreased fat mass (∼2.4 kg), BP, and improvements to performance on the FPPA while preserving high-intensity exercise. These data suggest that a 28-day CRD can benefit markers of health in professional FF without detriments to occupational performance.

Włodarczyk, M, Kusy, K, Słomińska, E, Krasiński, Z, and Zieliński, J. Change in lactate, ammonia, and hypoxanthine concentrations in a 1-year training cycle in highly trained athletes: applying biomarkers as tools to assess training status. J Strength Cond Res 34(2): 355–364, 2020—The aim was to determine changes in biomarker (LA, NH3, purine metabolites) blood concentration during graded exercise and recovery throughout an annual training cycle in highly trained athletes of different training profiles. The study included 12 sprinters (SP, 21–30 years), 11 triathletes (TR, 20–31 years), 12 futsal players (FU, 19–31 years), and 13 amateur runners (AM, 20–33 years). Purine metabolite (hypoxanthine, xanthine, uric acid), ammonia (NH3), and lactate (LA) concentrations were determined at rest, during an incremental treadmill exercise test (every 3 minutes), and during recovery (5, 10, 15, 20, and 30 minutes postexercise) in 4 phases of an annual training cycle. Purine metabolite concentration was determined from plasma, whereas LA and NH3 from whole blood. For LA during exercise and recovery, certain significant differences between training phases within groups were observed for FU, TR, and SP but not for AM. For NH3, the greatest differences between examination points were observed for SP and TR near maximal exercise and in the first few stages of recovery. For hypoxanthine (Hx), the largest amount of differences between examination points was observed for FU, TR, and FU throughout the entire exercise spectrum. Biomarker concentration dynamics change during an incremental exercise test and postexercise in an annual training cycle. Biomarker responses differ depending on training type and magnitude of training loads used in various phases of an annual training cycle. When assessing training status using an incremental exercise test throughout an annual training cycle, NH3 and Hx concentration changes are more sensitive compared with LA.

Published: August 2019

O período da adolescência é permeado por múltiplas alterações biopsicossocioculturais, expondo-os a diversos agravos à sua saúde. As oficinas educativas emergem como uma metodologia ativa que visa romper com o modelo hegemônico das práticas de educação em saúde, com vistas à promoção da saúde, bem como emancipação e transformação por meio da ação-reflexão-ação, na busca do empoderamento para a cidadania, política, cultura de paz, qualidade de vida e bem-estar. O objetivo do projeto foi favorecer o desenvolvimento de oficinas educativas junto a adolescentes em situação de vulnerabilidade social. Realizaram-se oficinas sobre temáticas relacionadas à saúde, bem-estar, qualidade de vida, desenvolvimento pessoal, empoderamento, cidadania e construção de projeto de vida. As ações foram planejadas e executadas de acordo com as necessidades e os anseios do público-alvo, como também da equipe profissional atuante no serviço. Ressalta-se a potencialidade da abordagem dessas temáticas no período da adolescência, visto que é a fase de consolidação de práticas e saberes que refletirão nas condutas e hábitos, relacionados ao tripé saúde-doença-cuidado, pelo resto da vida. Considera-se, portanto, que o alto grau de vulnerabilidade evidenciado na adolescência aponta como um potencial grupo para realização de atividades extensionistas, pois o aprendizado e a vivência proporcionados pelo projeto podem corroborar com a formação de agentes de mudanças e difusores desses saberes para a comunidade.

No ensino de ciências existe uma pertinente dificuldade no tocante a aplicabilidade dos temas, de forma transversal, relativos à História e Cultura Afro-brasileira e Indígena, bem como é notório o desafio da renovação do modelo tradicional de ensino. Logo, a utilização de metodologias alternativas, tais como os jogos didáticos, apresentam-se como medidas indispensáveis para o fomento dos processos educacionais. Assim, o objetivo deste trabalho é colaborar com os processos de ensino e aprendizagem, no qual, com a utilização do jogo “Radiogan”, os alunos compreendam os principais aspectos que estão envoltos no conteúdo de radioatividade, refletindo sobre as questões socioeconômicas da cidade de Acra, capital de Gana. Além disso, de modo específico, pretendíamos: i) cooperar no reconhecimento, pelos indivíduos, da importância do descarte correto do lixo eletrônico; ii) auxiliar para disseminação no plano social, de ações de sensibilização a respeito da temática trabalhada; iii) contribuir com a formação de sujeitos críticos, que compreendam e sejam capazes de identificar os fatores sociais que influenciam a capital de Gana, Acra, onde está localizado o maior lixão eletrônico do mundo. Além de atingir, os resultados esperados, o jogo “Radiogan” contribuiu para aguçar os estudantes para o contexto que tange as questões históricas e culturais, como o sustento de indivíduos mediante a exploração de lixo eletrônico na África. Ademais, o material e a aplicação deste serviu, também, para consolidar em nós, futuros educadores, a ampliação de conhecimentos específicos juntamente com um olhar mais voltado para novas práticas didáticas.

Published: August 2019

O Brasil encontra grandes dificuldades em oferecer os serviços de saneamento básico para toda a população, o que reforça as desigualdades sociais. Para que haja a cobrança e atuação cidadã, é necessário que os indivíduos compreendam a complexidade dos serviços concernentes ao saneamento e o meio onde vivem. Nesse sentido, vimos que o saneamento básico pode ser articulado à Educação Ambiental (EA) Crítica, pois este é um processo educativo que prioriza a transformação social como necessidade para a superação da crise ambiental atual. Por isso, nos propomos a desenvolver um Projeto de Extensão na Universidade Estadual do Norte do Paraná, Jacarezinho (UENP-CJ), levantando dados sobre o saneamento básico e desenvolvimento de ações de EA numa escola pública estadual. Percebermos que as ações favoreceram o fortalecimento da EA Crítica no espaço escolar, possibilitando aos estudantes compreenderem a realidade onde vivem de maneira mais ampla e complexa no que se refere ao saneamento básico, atuando como cidadãos críticos na cobrança por serviços de qualidade que se constituem como direitos da população.

Os impactos ocasionados por desastres naturais estão diretamente ligados com o desenvolvimento regional, seja por aspectos econômicos, sociais, culturais ou ambientais. Nesse sentido, é necessário ampliar as campanhas de sensibilização e educação ainda nos anos iniciais da educação fundamental. Diante desta perspectiva, o presente artigo tem por objetivo apresentar e analisar o programa de conscientização Defesa Civil na Escola da Defesa Civil, do munícipio de Blumenau, oferecido às escolas da rede pública de ensino. O acompanhamento do programa foi realizado no contexto das atividades do projeto de extensão Atmosfera, da Universidade Regional de Blumenau, que trata da prevenção e mitigação aos riscos de desastres. Como método de trabalho e investigação, foram realizados estudos bibliográficos e documentais, acompanhadas as atividades propostas pela Defesa Civil, analisada a metodologia aplicada no programa e a participação dos estudantes ao longo do processo. Por fim, foi proposta uma forma de abordagem que privilegie a interação e o uso de tecnologias digitais nesse processo de formação. A partir disso, concluiu-se sobre a necessidade de criar novas formas de abordagem que proporcionem mais interações e utilizem recursos tecnológicos, de modo a oferecer experiências aos estudantes sobre as questões relacionadas à prevenção e mitigação aos riscos de desastres mais próximas aos interesses.

Microglia Mediate HIV-1 gp120-Induced Synaptic Degeneration in Spinal Pain Neural Circuits
Authors: Ru Wenjuan , Liu Xin , Bae Chilman , Shi Yuqiang , Walikonis Randall , Mo Chung Jin , Tang Shao-Jun
Published: August 2019

HIV-1 infection of the nervous system causes various neurological diseases, and synaptic degeneration is likely a critical step in the neuropathogenesis. Our prior studies revealed a significant decrease of synaptic protein, specifically in the spinal dorsal horn of patients with HIV-1 in whom pain developed, suggesting a potential contribution of synaptic degeneration to the pathogenesis of HIV-associated pain. However, the mechanism by which HIV-1 causes the spinal synaptic degeneration is unclear. Here, we identified a critical role of microglia in the synaptic degeneration. In primary cortical cultures (dayin vitro14) and spinal cords of 3- to 5-month-old mice (both sexes), microglial ablation inhibited gp120-induced synapse decrease. Fractalkine (FKN), a microglia activation chemokine specifically expressed in neurons, was upregulated by gp120, and knockout of the FKN receptor CX3CR1, which is predominantly expressed in microglia, protected synapses from gp120-induced toxicity. These results indicate that the neuron-to-microglia intercellular FKN/CX3CR1 signaling plays a role in gp120-induced synaptic degeneration. To elucidate the mechanism controlling this intercellular signaling, we tested the role of the Wnt/β–catenin pathway in regulating FKN expression. Inhibition of Wnt/β-catenin signaling blocked both gp120-induced FKN upregulation and synaptic degeneration, and gp120 stimulated Wnt/β-catenin-regulated FKN expression via NMDA receptors (NMDARs). Furthermore, NMDAR antagonist APV, Wnt/β-catenin signaling suppressor DKK1, or knockout of CX3CR1 alleviated gp120-induced mechanical allodynia in mice, suggesting a critical contribution of the Wnt/β–catenin/FKN/CX3R1 pathway to gp120-induced pain. These findings collectively suggest that HIV-1 gp120 induces synaptic degeneration in the spinal pain neural circuit by activating microglia via Wnt3a/β-catenin-regulated FKN expression in neurons.

SIGNIFICANCE STATEMENTSynaptic degeneration develops in the spinal cord dorsal horn of HIV patients with chronic pain, but the patients without the pain disorder do not show this neuropathology, indicating a pathogenic contribution of the synaptic degeneration to the development of HIV-associated pain. However, the mechanism underlying the synaptic degeneration is unclear. We report here that HIV-1 gp120, a neurotoxic protein that is specifically associated with the manifestation of pain in HIV patients, induces synapse loss via microglia. Further studies elucidate that gp120 activates microglia by stimulating Wnt/β-catenin-regulated fractalkine in neuron. The results demonstrate a critical role of microglia in the pathogenesis of HIV-associated synaptic degeneration in the spinal pain neural circuit.

Adapting Writing Assignments on Socioscientific Issues for Large-Enrollment Introductory Cell Biology Courses
Authors: Laybourn Paul J. , Brisch Ellen , Wallace Alison M. , Balgopal Meena M.
Published: August 2019

Much evidence supports the role of writing-to-learn (WTL) assignments in improving student learning and argumentation skills. However, designing effective assignments can be challenging for instructors. We describe a process for modifying WTL assignments that were originally developed for small undergraduate biology classes (24 students) for use in large introductory cell biology courses (>80 students). Students explore a socioscientific issue (cancer treatment) intended to engage them. Students learn content through reading journal articles and textbook chapters, attending class, and participating in discussions. All along, students participate in iterative writing assignments and engage in peer evaluation and self-evaluation. Finally, students write persuasive arguments about how best to treat cancer. We describe how instructors can develop their own WTL assignments in their large biology courses.
Propaganda and Reception in Nineteenth-Century Music Criticism: Maurice Schlesinger, Henri Herz, and the Gazette musicale
Authors: Weitz Shaena B.
Published: August 2019

In the mid-1830s, Henri Herz (1803–88) was an internationally renowned pianist, but his reputation today, for the most part, is that of a second-rate musician who wrote trivial variations on opera themes. This enduring picture of Herz was painted first in France in 1834 by the Gazette musicale. The Gazette’s campaign has been understood by modern scholars as a conspicuous moment in a broad aesthetic shift away from French salon music and toward high German Romanticism, and the Gazette has garnered praise for its prescience. But a closer examination of the Gazette’s articles, the events surrounding the coverage such as a pistol duel and a libel case, contemporary correspondence, and Herz’s publishing record indicate that the Gazette’s negative treatment of Herz was not an organic assessment of his output, but rather a revenge scheme orchestrated by the Gazette’s owner and Herz’s former publisher, Maurice Schlesinger (1798–1871). As a case study, the Gazette’s Herz campaign exposes the endemic corruption of the nineteenth-century press that has been portrayed as an unseemly rarity rather than a central component of historical criticism’s production. But taken more broadly, the Gazette’s articles on Herz highlight limitations in the history of reception. This article turns to media studies to explore the problematic relationship between propaganda and reception and shows how the Gazette, and other nineteenth-century journals, are still manipulating our cognition.
Genomic Prediction Including SNP-Specific Variance Predictors
Authors: Mouresan Elena Flavia , Selle Maria , Rönnegård Lars
Published: August 2019

The increasing amount of available biological information on the markers can be used to inform the models applied for genomic selection to improve predictions. The objective of this study was to propose a general model for genomic selection using a link function approach within the hierarchical generalized linear model framework (hglm) that can include external information on the markers. These models can be fitted using the well-established hglm package in R. We also present an R package (CodataGS) to fit these models, which is significantly faster than the hglm package. Simulated data were used to validate the proposed model. We tested categorical, continuous and combination models where the external information on the markers was related to 1) the location of the QTL on the genome with varying degree of uncertainty, 2) the relationship of the markers with the QTL calculated as the LD between them, and 3) a combination of both. The proposed models showed improved accuracies from 3.8% up to 23.2% compared to the SNP-BLUP method in a simulated population derived from a base population with 100 individuals. Moreover, the proposed categorical model was tested on a dairy cattle dataset for two traits (Milk Yield and Fat Percentage). These results also showed improved accuracy compared to SNP-BLUP, especially for the Fat% trait. The performance of the proposed models depended on the genetic architecture of the trait, as traits that deviate from the infinitesimal model benefited more from the external information. Also, the gain in accuracy depended on the degree of uncertainty of the external information provided to the model. The usefulness of these type of models is expected to increase with time as more accurate information on the markers becomes available.
Transmission of Vaccine-Strain Varicella-Zoster Virus: A Systematic Review
Authors: Marin Mona , Leung Jessica , Gershon Anne A.
Published: August 2019

CONTEXT:

Live vaccines usually provide robust immunity but can transmit the vaccine virus.

OBJECTIVE:

To assess the characteristics of secondary transmission of the vaccine-strain varicella-zoster virus (Oka strain; vOka) on the basis of the published experience with use of live varicella and zoster vaccines.

DATA SOURCES:

Systematic review of Medline, Embase, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature, and Scopus databases for articles published through 2018.

STUDY SELECTION:

Articles that reported original data on vOka transmission from persons who received vaccines containing the live attenuated varicella-zoster virus.

DATA EXTRACTION:

We abstracted data to describe vOka transmission by index patient’s immune status, type (varicella or herpes zoster) and severity of illness, and whether transmission was laboratory confirmed.

RESULTS:

Twenty articles were included. We identified 13 patients with vOka varicella after transmission from 11 immunocompetent varicella vaccine recipients. In all instances, the vaccine recipient had a rash: 6 varicella-like and 5 herpes zoster. Transmission occurred mostly to household contacts. One additional case was not considered direct transmission from a vaccine recipient, but the mechanism was uncertain. Transmission from vaccinated immunocompromised children also occurred only if the vaccine recipient developed a rash postvaccination. Secondary cases of varicella caused by vOka were mild.

LIMITATIONS:

It is likely that other vOka transmission cases remain unpublished.

CONCLUSIONS:

Healthy, vaccinated persons have minimal risk for transmitting vOka to contacts and only if a rash is present. Our findings support the existing recommendations for routine varicella vaccination and the guidance that persons with vaccine-related rash avoid contact with susceptible persons at high risk for severe varicella complications.

This implies that coaching needs to be empowered intensively.
A Non–Convex Optimization Approach to Correlation Clustering
Authors: Thiel Erik , Chehreghani Morteza Haghir , Dubhashi Devdatt
Published: August 2019

We develop a non-convex optimization approach to correlation clustering using the Frank-Wolfe (FW) framework. We show that the basic approach leads to a simple and natural local search algorithm with guaranteed convergence. This algorithm already beats alternative algorithms by substantial margins in both running time and quality of the clustering. Using ideas from FW algorithms, we develop subsampling and variance reduction paradigms for this approach. This yields both a practical improvement of the algorithm and some interesting further directions to investigate. We demonstrate the performance on both synthetic and real world data sets.
Transferable Attention for Domain Adaptation
Authors: Wang Ximei , Li Liang , Ye Weirui , Long Mingsheng , Wang Jianmin
Published: August 2019

Recent work in domain adaptation bridges different domains by adversarially learning a domain-invariant representation that cannot be distinguished by a domain discriminator. Existing methods of adversarial domain adaptation mainly align the global images across the source and target domains. However, it is obvious that not all regions of an image are transferable, while forcefully aligning the untransferable regions may lead to negative transfer. Furthermore, some of the images are significantly dissimilar across domains, resulting in weak image-level transferability. To this end, we present Transferable Attention for Domain Adaptation (TADA), focusing our adaptation model on transferable regions or images. We implement two types of complementary transferable attention: transferable local attention generated by multiple region-level domain discriminators to highlight transferable regions, and transferable global attention generated by single image-level domain discriminator to highlight transferable images. Extensive experiments validate that our proposed models exceed state of the art results on standard domain adaptation datasets.
Exploiting Local Feature Patterns for Unsupervised Domain Adaptation
Authors: Wen Jun , Liu Risheng , Zheng Nenggan , Zheng Qian , Gong Zhefeng , Yuan Junsong
Published: August 2019

Unsupervised domain adaptation methods aim to alleviate performance degradation caused by domain-shift by learning domain-invariant representations. Existing deep domain adaptation methods focus on holistic feature alignment by matching source and target holistic feature distributions, without considering local features and their multi-mode statistics. We show that the learned local feature patterns are more generic and transferable and a further local feature distribution matching enables fine-grained feature alignment. In this paper, we present a method for learning domain-invariant local feature patterns and jointly aligning holistic and local feature statistics. Comparisons to the state-of-the-art unsupervised domain adaptation methods on two popular benchmark datasets demonstrate the superiority of our approach and its effectiveness on alleviating negative transfer.

Published: August 2019

We propose a scalable stochastic variational approach to GP classification building on Pólya-Gamma data augmentation and inducing points. Unlike former approaches, we obtain closed-form updates based on natural gradients that lead to efficient optimization. We evaluate the algorithm on real-world datasets containing up to 11 million data points and demonstrate that it is up to two orders of magnitude faster than the state-of-the-art while being competitive in terms of prediction performance.

Design of a spiral-shaped piezoelectric energy harvester for powering pacemakers
Authors: Anand Ashutosh , Kundu Sudip
Published: August 2019

In this paper, a spiral-shaped piezoelectric cantilever structure is proposed to harvest the energy from the vibration of a heartbeat. The proposed cantilever structure is 14 μm thin and has outer dimensions of 6 mm × 6 mm. The spiral structure reduces the stiffness of the cantilever beam, which reduces the resonant frequency. A proof mass is introduced in the spiral structure to reduce further the resonant frequency of the cantilever beam. Due to its biocompatible nature, zinc oxide (ZnO) is used as the piezoelectric material for the design. The proposed structure has a resonant frequency of 30·6 Hz, which is suitable for harvesting energy from the human heartbeat. The resonant frequency of the proposed 3-turn spiral cantilever beam is 33·18% lower than that of the 2·5-turn spiral cantilever beam and 54·93% lower than that of the 2-turn spiral. The proposed harvester generates a peak output open-circuit voltage of 4 V and a peak output power of 5·3 μW at a resonant frequency of 30·6 Hz for a sinusoidal acceleration of 1g (1g = 9·8 m/s2).

Although buildings are excited by translational and rotational earthquake components, only translational components are considered in seismic loads. The effects of earthquake torsional components on building responses were studied in this work. For this purpose, the torsional component of 14 earthquakes was extracted from their translational components. Symmetric and asymmetric idealised single-storey models were analysed by considering the torsional and translational components. The models considered five different values of the uncoupled torsional frequency to uncoupled translational frequency ratio (Ω = ωθ/ωx = 1·5, 1·25, 1, 0·75, 0·5), with their lateral period varying from 0·05 to 2 s. The displacements of the left-hand side, right-hand side and centre of the diaphragm, the diaphragm rotation about the centre of mass and the base shear were studied. The results indicated that the effect of the torsional component on the non-linear responses of the building was considerable, and ignoring this effect led to an underestimation of the responses. The increase in the building's responses due to the torsional component was found to depend significantly on the value of Ω and the stiffness eccentricity. The maximum growth of the displacement of torsionally stiff and torsionally flexible buildings was 51% and 155%, respectively. The diaphragm rotation can be increased to 154% in the asymmetric systems.

Published: August 2019

Fibre-reinforced engineered cementitious composites are increasing being used in construction due to their superior toughness and durability. For composite structural members additionally reinforced with steel bars, the bond–slip relationship between the composite and reinforcing bars is an important parameter for designers. To understand the bond behaviour between Chinese 500 MPa steel bars and composites, pull-out tests were conducted to study the influence of the bar diameter, cover thickness and embedded length on bond properties under tension. The results indicated that the process of the bond–slip failure for 500 MPa steel bars in composites can be divided into three stages: ascent, descent and remnant. The bond strength increased with a decrease in bar diameter, while shortening of the embedment length enhanced the bond strength. Specimens with a larger cover thickness achieved higher bond strength, but the enhancement in bond strength was negligible for specimens with a cover thickness greater than 55 mm. A formula for calculating the bond strength for Chinese 500 MPa reinforcing bars in composites was developed based on the experimental results and a consistent model for the bond stress–slip relationship was also obtained.
Post-fire reliability analysis of concrete beams retrofitted with CFRPs: a new approach
Authors: Cai Bin , Zhang Bo , Fu Feng
Published: August 2019

A new reliability analysis approach for the flexural capacity of post-fire reinforced concrete (RC) beams retrofitted with carbon-fibre-reinforced polymers/plastics (CFRPs) is proposed. In this approach, the thermal parameters of RC beams are first determined to enable heat transfer analysis in Abaqus. Based on the thermal response obtained from the heat transfer analysis, a section method is used to calculate the post-fire residual flexural capacity of RC beams. Reliability analysis of the beams retrofitted with CFRPs is subsequently performed using the Monte Carlo method. The effects of fire exposure time, concrete cover thickness and CFRP usage on the reliability of the flexural capacity of RC beams after fire exposure were studied. This new approach was found to be accurate and effective. It provides an effective reliable model for the evaluation of the mechanical properties of post-fire RC beams strengthened with CFRPs.
Interactive structural design of hyperbolic grid shells
Authors: Chahade Tarick , Schober Kay-Uwe , Morillas Leandro
Published: August 2019

Local and global design processes are equally time-phased and consider multiple goals, such as architecture, engineering and manufacturing. This paper presents a global modelling concept for hyperbolic grid shells with parametric methodologies to demonstrate alternatives to conventional structural designs composed of iterative workflows. The modelling concept provides a smooth and interactive design process for the optimisation and analysis of hyperbolic shapes. Moreover, modern timber architecture is increasingly moving towards double-curved forms, for which current timber joining methods do not offer fully adequate solutions. The design and manufacturing of multi-axial joints in spatial structures, such as space frameworks or grid shells, can greatly influence the appearance when more than two members are joined in and out of plane. In this paper, innovative grouted round timber connections have been adapted for the design of hyperbolic structures with the advantage of no requirement for concave modification of the cross-sections.
Transparency and Collateral: The Design of CCPs' Loss Allocation Rules

This paper adopts a mechanism design approach to study optimal clearing arrangements for bilateral financial contracts in which an assessment of counterparty risk is crucial for efficiency. The economy is populated by two types of agents: a borrower and lender. The borrower is subject to limited commitment and holds private information about the severity of such lack of commitment. The lender can acquire information at a cost about the commitment of the borrower, which affects the assessment of counterparty risk. When truthful revelation by the borrower is not incentive compatible, the mechanism designer optimally trades off the value of information about the lack of commitment of the borrower with the cost of incentivizing the lender to acquire such information. Central clearing of these financial contracts through a central counterparty (CCP) allows lenders to mutualize their counterparty risks, but this insurance may weaken incentives to acquire and reveal informatio n about such risks. If information acquisition is incentive compatible, then lenders choose central clearing. If it is not, they may prefer bilateral clearing to prevent strategic default by borrowers and to economize on costly collateral. Central clearing is analyzed under different institutional features observed in financial markets, which place different restrictions on the contract space in the mechanism design problem. The interaction between the costly information acquisition and the limited commitment friction differs significantly in each clearing arrangement and in each set of restrictions. This results in novel lessons about the desirability of central versus bilateral clearing depending on traders&#x27; characteristics and the institutional features defining the operation of the CCP.
Monetary Policy and Bank Equity Values in a Time of Low and Negative Interest Rates
Authors: Ampudia Miguel , Van den Heuvel Skander J.
Published: August 2019

Does banks&amp;#x27; exposure to interest rate risk change when interest rates are very low or even negative? Using a high-frequency event study methodology and intraday data, we find that the effect of surprise interest rate cuts announced by the ECB on European bank equity values – an effect that is normally positive – has become negative since interest rates in the euro area reached zero and below. Since then, a further unexpected cut of 25 basis points in the short-term policy rate lowered banks&amp;#x27; stock prices by about 2% on average, compared to a 1% increase in normal times. In the cross section, this &amp;#x27;reversal&amp;#x27; was far more pronounced for banks with a more traditional, deposit-intensive funding mix. We argue that the reversal as well as its cross-sectional pattern can be explained by the zero lower bound on interest rates on retail deposits.

Authors: Huynh Thi Lan , Nguyen Uyen Nu Thuy
Published: August 2019

Digital technologies have become a driver of change that exerts tremendous impact across the disciplines, including education. The Flipped classroom model, carried out in a technology-enhanced environment, has been proven to bring educational innovations.  However, in the Vietnamese educational context, the adoption of the flipped model in interpreting courses for undergraduate students has been hardly touched upon in the existing literature. This current study is, therefore, an attempt to examine English-majored students’ perceptions about this teaching model on Moodle Learning Management Platform and put forward some proposals in the design and implementation of the Flipped Interpreting course. The data were collected using both quantitative and qualitative methods, including a Likert-scale questionnaire and individual interviews. The results revealed that students had positive perceptions toward the adoption of Flipped model and Moodle platform. Analyzing the interconnection of three domains in CoI framework and the additional domain of Technology Use, the authors then offer further recommendations for effective implementation of the model in the EFL classroom context.
The Translatability of Indonesian Modality into English
Authors: Susini Made , Yadnya Ida Bagus Putra , Puspani Ida Ayu Made
Published: August 2019

Translation is a bilingual activity and the languages involved in translation have their own lexico-grammatical features. Modality which can be categorized into modalization and modulation refers to grammatical realization of interpersonal meaning. Systems of modality are different among languages and these differences become important to be well handled in translation. This research is focused on the translatability of modality from Indonesian into English. It investigates the effects of translation strategies applied by the translator to the contextual meaning of target text that is identified and analyzed from the perspectives of type, value, and orientation of modality based on Halliday’s Systemic Functional Grammar. The result shows that modality in Indonesian can be rendered into English. Shifts due to the value or orientation of modality cause differences of the contextual meanings between Indonesian and English texts.
