Crafting Emotions: The valence of time in narratives about the future of Europe in the Council of Europe (1949)

How are emotional narratives used to mobilise support for or opposition against policy ideas about the institutional set-up of European integration? This article systematically examines the first General Debate of the Consultative Assembly of the Council of Europe in 1949, which featured as a laboratory for the rise and demise of various blueprints for European integration. This article makes a threefold contribution. First, it introduces a narrative approach that combines the valence of emotions with their temporal dimension. Second, it demonstrates how these emotionally charged narratives of hope, redemption, fear and sacrifice provide the affective glue of an emerging (transnational) emotional community that cuts through nationality and political colour. Third, taking a historical approach this article points at the need to historicise the role of emotions in European integration.
Effect of acoustic birefringence on acoustooptic interaction in birefringent two-mode optical fibers

The acoustic birefringence in a highly birefringent (Hi-Bi) two-mode optical fiber is measured and shown to be about 0.8%. The birefringence is primarily caused by a cladding ellipticity in excess of 1%. The effect of the softer stress-inducing elements is small in comparison. The effects of misalignment of the acoustic and optical axes is studied in detail using both continuous-wave and pulsed acoustooptic interaction. In the Hi-Bi fiber, the misalignment is approximately 20/spl deg/. The acoustic birefringence and misalignment have a profound effect on the spectral characteristic of tunable acoustooptic notch- and passband filters, giving rise to double spectral peaks. The birefringence is not specific to Hi-Bi fibers. The same effect is demonstrated in a birefringent elliptic core fiber, and it should be expected also in standard telecom single-mode fibers. In tunable acoustooptic notch filters based on coupling to cladding modes in standard telecom fibers with ellipticity of the order of 1% the acoustic birefringence may cause double absorption peaks separated by more than 4 nm. It is also shown that acoustic birefringence provides guiding of the spatial orientation of the acoustic flexural waves, even if the fiber is twisted. This guiding effect eases the construction of acoustooptic components with long interaction length.
Inverter nonlinearities and discrete-time vector current control

The authors study all-digital discrete-time vector current control loops containing a voltage-fed inverter in series with a permanent magnet synchronous motor. Normal operation of the typical pulse width modulating voltage fed inverter introduces nonlinear distortion into the voltage and the current waveforms of the motor. The authors consider both the causes and the attenuation of these disturbances using all-digital control. An effective, fully digital current controller is developed, and experimental results from a Motorola 68020 microprocessor-based system are presented. <<ETX>>
Report of Health Care Provider Recommendation for COVID-19 Vaccination Among Adults, by Recipient COVID-19 Vaccination Status and Attitudes — United States, April–September 2021

Vaccination is critical to controlling the COVID-19 pandemic, and health care providers play an important role in achieving high vaccination coverage (1). To examine the prevalence of report of a provider recommendation for COVID-19 vaccination and its association with COVID-19 vaccination coverage and attitudes, CDC analyzed data among adults aged ≥18 years from the National Immunization Survey-Adult COVID Module (NIS-ACM), a nationally representative cellular telephone survey. Prevalence of report of a provider recommendation for COVID-19 vaccination among adults increased from 34.6%, during April 22-May 29, to 40.5%, during August 29-September 25, 2021. Adults who reported a provider recommendation for COVID-19 vaccination were more likely to have received ≥1 dose of a COVID-19 vaccine (77.6%) than were those who did not receive a recommendation (61.9%) (adjusted prevalence ratio [aPR] = 1.12). Report of a provider recommendation was associated with concern about COVID-19 (aPR = 1.31), belief that COVID-19 vaccines are important to protect oneself (aPR = 1.15), belief that COVID-19 vaccination was very or completely safe (aPR = 1.17), and perception that many or all of their family and friends had received COVID-19 vaccination (aPR = 1.19). Empowering health care providers to recommend vaccination to their patients could help reinforce confidence in, and increase coverage with, COVID-19 vaccines, particularly among groups known to have lower COVID-19 vaccination coverage, including younger adults, racial/ethnic minorities, and rural residents.
Multibody dynamics modelling of the freight train bogie system

Previous work in the railway technology laboratory at Virginia Polytechnic Institute and State University (Virginia Tech) focused on better capturing the dynamics of the friction wedge, modelled using three-dimensional rigid body dynamics with unilateral contact conditions. The current study extends the previous work to a half-bogie model treated as an application of multibody dynamics with unilateral contact to model the friction wedge interactions with the bolster and the sideframe. The half-bogie model was derived using MATLAB and functions as a three dimensional, dynamic, and multibody dynamics model comprised of four rigid bodies: a bolster, two friction wedges, and a sideframe assembly. This expanded model allows each wedge four degrees of freedom: vertical displacement, longitudinal displacement (between the bolster and sideframe), pitch (rotation around the lateral axis), and yaw (rotation around the vertical axis). The bolster and the sideframe are constrained to have only the vertical degree of freedom. The geometry of these bodies can be adjusted for various simulation scenarios. The bolster can be initialised with a pre-defined yaw (rotation around the vertical axis) and the sideframe may be initialised with a pre-defined pitch/toe (rotation around the lateral axis). The results of the multibody dynamics in half-bogie model simulation are shown in comparison with results from NUCARS®, an industry standard in train-modelling software, for similar inputs.
Importing export zones: processes and impacts of replicating a Chinese model of urbanization in rural south India

ABSTRACT This article examines the development of a south Indian “industrial city”, modelled on a Chinese counterpart. The privately-operated city is a key example of India’s new-style Special Economic Zones (SEZs). These represent a national shift, motivated by China’s SEZ success, from enclave-style “export processing zones” to integrated townships. Drawing on fieldwork from 2018, we compare three issues with the Chinese “model”: the city’s establishment and spatial planning; the gendered hiring practices of its firms; and its incorporation of local villages. These three aspects represent different mechanisms through which the “model” is translated into the Indian context, by different actors, with different outcomes. In line with policy mobilities scholarship, we argue that models cannot be straightforwardly replicated, and we call for more attention to the outcomes of attempted replication, in particular the urban development implications of selective, complex, multi-level adaptation of a Chinese “model” and its interaction with local Indian contexts.
RETINAL VASCULAR TREE CONSTRUCTION WITH MULTIMODAL FLUORESCEIN ANGIOGRAM SEQUENCE

In this article, we present a method to construct retinal vascular tree with the spatial information and temporal intensity profile of vessels. The significance of the work is to assist in clinical studies of diagnosis of cardiovascular diseases, such as hypertension, which manifest abnormalities in either venous and/or arterial vascular systems. For temporal intensity profile, fluorescein angiogram (FA) is adopted to ensure continuity of vessel segments along time. We separate retinal vascular tree construction into two main steps — vessel extraction and vessel grouping. In vessel extraction, we use an existing algorithm that applies multiscale matched filtering and vessel likelihood measure to extract vessel segments and its spatial information in color retinal image. Vessel segments are grouped using extended Kalman filter to take into consideration continuities in curvature, width, and fluorescein angiogram sequence changes at the bifurcation or crossover point. The algorithm is evaluated on a clinical data set from Taipei Veterans' General Hospital, and the results are compared with the ground truth images provided by a physician. The results show that our method reaches an average correctness rate of 91.48%.
Zirconium-Based Metal Organic Frameworks for the Capture of Carbon Dioxide and Ethanol Vapour. A Comparative Study

This paper reports on the comparison of three zirconium-based metal organic frameworks (MOFs) for the capture of carbon dioxide and ethanol vapour at ambient conditions. In terms of efficiency, two parameters were evaluated by experimental and modeling means, namely the nature of the ligands and the size of the cavities. We demonstrated that amongst three Zr-based MOFs, MIP-202 has the highest affinity for CO2 (−50 kJ·mol−1 at low coverage against around −20 kJ·mol−1 for MOF-801 and Muc Zr MOF), which could be related to the presence of amino functions borne by its aspartic acid ligands as well as the presence of extra-framework anions. On the other side, regardless of the ligand size, these three materials were able to adsorb similar amounts of carbon dioxide at 1 atm (between 2 and 2.5 µmol·m−2 at 298 K). These experimental findings were consistent with modeling studies, despite chemisorption effects, which could not be taken into consideration by classical Monte Carlo simulations. Ethanol adsorption confirmed these results, higher enthalpies being found at low coverage for the three materials because of stronger van der Waals interactions. Two distinct sorption processes were proposed in the case of MIP-202 to explain the shape of the enthalpic profiles.
Nexus between green financing, economic risk, political risk and environment: evidence from China

Abstract This study provides fresh evidence regarding the dynamic association that is believed to exist in relation to green finance (GF), economic growth (GDP), political risk (PR), economic risk (ER), and carbon dioxide (CO2) emissions. It therefore uses the dataset pertaining to China from most recent time-series – covering the period spanning from the years of 1990 to 2020, by employing the Morlet Wavelet Analysis technique. The empirical findings of the wavelet power spectrum reveal that green finance GF and ER are vulnerable in the short- and long-run, and the short-run, respectively. At the same time, no vulnerability has been observed in the GDP, PR, and CO2 emissions. In addition to this, the wavelet coherence also reveals the bidirectional causal association that exists between GF-CO2 and ER-CO2, but only in the short run. It must also be taken into consideration that the causal influence of CO2 is deemed to be greater than the GF and ER, respectively. Besides this, a bidirectional causal nexus also exists between the GDP and CO2 emissions, only in the long run. Furthermore, the association between the economic growths follows both the phase and antiphase associations. Moreover, the study also reveals that there is no significant causal link between the PR and CO2 emissions. The results emphasize that the significance of green finance investment will tend to increase with strict policy implications, stabilization or minimization of economic risk and political risk. The same will also take place while promoting environmentally friendly production via economic growth, so as to reduce CO2 emission in the region taken into account.
Evaluation of Sky Luminance and Radiance Models Using Data of North Bangkok

Abstract The tropical sky is highly luminous. This gives rise to expectation of its high potential for daylighting. The availability of an accurate luminance distribution for daylight from the sky would help advance the movement for daylighting. On the other hand, accurate radiance distribution model is also needed to help manage the undesirable heat gain due to solar radiation penetration in air-conditioned buildings. Towards these ends, eight luminance and radiance distribution models were evaluated against luminance and radiance measurements recorded in a station located north of Bangkok. Due to prevalence of intermediate and cloudy sky conditions in the tropical region, attention was paid to seeking models that could perform well under these conditions. It turns out that a number of models are acceptable, but no single model performs distinctively well for the prevalent conditions.
EXPLOSION AND FIRE ANALYSIS OF STEEL FRAMES USING FIBER ELEMENT APPROACH

Since the September 11th terrorist attacks, the research and engineering communities have given significant attention to building performance under combined effects of impact, explosion, and fire. This paper presents a numerical approach for inelastic transient analysis of steel frame structures subjected to explosion loading followed by fire. The approach adopts the use of beam-column element and fiber element to enable a realistic modeling of the overall framework subjected to localized explosion and fire. Detailed requirements for modeling elasto-plastic materials subjected to elevated temperature and high-strain rates are presented. Verification examples are provided. The influence of blast loads on the fire resistance of a multistory steel frame is studied.
OverStitch Sx Endoscopic suturing system in minimally invasive endoscopic procedures: overview of its safety and efficacy and comparison to oversticthTM

ABSTRACT Introduction OverStitch endoscopic suturing enables advanced closure by tissue approximation via endoscopically placed sutures with the ability to customize suture patterns. Newer OverStitch generation also known as OverStitch Sx overcame the limitation of the previous generation and is compatible with 20 single channel scopes over four platforms with greater maneuverability and visibility. Areas covered In this article we will focus on the differences between three generations of OverStitch. In addition, we will review existing literature on the efficacy of OverStitch in the management of full thickness defect closure, fistula and leaks repair, stent fixation, and bariatric surgeries along with its complications and limitations. Expert opinion Assembling overstitch takes less than five minutes and the correct sequence of system assembly is the key for a successful procedure. Transition from the second-generation OverStitch to OverStitch Sx may require three to five cases for learning curve.
Mental Readiness for Frontline Workers in Homelessness Services in Ottawa, Canada

This study investigated factors related to competency by assessing the mental readiness among highly recognized frontline workers in homelessness services (FWHSs) by means of self-completed questionnaires. A total of 35 highly respected FWHSs in Ottawa, Canada were identified by their peers and supervisors as “exceptional” for various specialty areas: addictions, mental health, hoarding, trauma and post-traumatic stress disorder (PTSD). An Operational Readiness Framework was used to examine how FWHSs perform at their best in challenging situations. A series of questionnaires were completed at a Think Tank to determine their mental readiness before, during and after challenging situations. Quantitative and qualitative analyses of mental readiness were performed to prioritize identified challenges. The study findings were then compared to the “Wheel of Excellence” based on results from elite athletes and other high performers such as surgeons, police, and air traffic controllers. The analysis revealed that mental readiness is required to achieve peak performance in addressing the challenges of homelessness. The balance between readiness (physical, technical and mental) and performance contributed to their competency and resiliency. Common elements of success were found: commitment, self-belief, positive imagery, mental preparation, full focus, distraction control and constructive evaluation. This investigation confirmed many similarities in mental readiness practices engaged by excellent FWHSs and other top professionals. This study offered, for the first time, a comprehensive understanding of specific high-performance readiness practices through a streetwise, frontline-worker perspective. Practical recommendations for training and assessment were provided relevant to excellence in homelessness services.
Spacecraft Data and Relay Management using Delay Tolerant Networking

NASA's demonstration of the successful transmission of relay data through the orbiting Mars Odyssey, Mars Global Surveyor, and Mars Express by the Mars Exploration Rovers has shown not only the benefit of using a relay satellite for multiple landed assets in a deep space environment but also the benefit of international standards for such architecture. As NASA begins the quest defined in the Vision for Exploration with robotic and manned missions to the Moon, continues its study of Mars, and is joined in these endeavors by countries world-wide, landed assets transmitting data through relay satellites will be crucial for completing mission objectives. However, this method of delivery of data will result in increased complexity in routing and prioritization of data transmission as the number of missions increases. Also, there is currently no standard method among organizations conducting such missions to return these data sets to Earth given a complex environment. One possibility for establishing such a standard is for mission designers to deploy protocols which fall under the umbrella of Delay Tolerant Networking (DTN). These developing standards include the Bundle Protocol (BP) which provides a standard, secure, store and forward mechanism designed for high latency and asymmetric communication links and the Licklider Transmission Protocol (LTP) which is used to provide a reliable deep space link transmission service.
Inter-annual variations observed in spring and summer Antarctic sea ice extent in recent decade

The growth and decay of sea ice are complex processes and have important feedback onto the oceanic and atmospheric circulation. In the Antarctic, sea ice variability significantly affects the primary productivity in the Southern Ocean and thereby negatively influences the performance and survival of species in polar ecosystem. In present days, the awareness on the sea ice variability in the Antarctic is not as matured as it is for the Arctic region. The present paper focuses on the inter-annual trends (1999-2009) observed in the monthly fractional sea ice cover in the Antarctic at 1 × 1 degree level, for the November and February months, derived from QuikSCAT scatterometer data. OSCAT scatterometer data from India’s Oceansat-2 satellite were used to asses the sea ice extent (SIE) observed in the month of November 2009 and February 2010 and its deviation from climatic maximum (1979-2002) sea ice extent (CMSIE). Large differences were observed between SIE and CMSIE, however, trend results show that it is due to the high inter-annual variability in sea ice cover. Spatial distribution of trends show the existence of positive and negative trends in the parts of Western Pacific Ocean, Ross Sea, Amundsen and Bellingshausen Seas (ABS), Weddell Sea and Indian ocean sector of southern ocean. Sea ice trends are compared with long-term SST trends (1982-2009) observed in the austral summer month of February. Large-scale cooling trend observed around Ross Sea and warming trend in ABS sector are the distinct outcome of the study.
The effects of the total bearing deformation on the performance of hydrodynamic thrust bearings

Purpose – The purpose of this paper is to study the effects of the total bearing deformation on the performance of hydrodynamic thrust bearings.Design/methodology/approach – Pressure distribution in the thrust bearing has been obtained using the Reynolds equation for the case of stable lubricant viscosity and isothermal conditions. Then, the deformation is found out by applying the constitutive equations for the linear elastic materials to both pad and runner. For the purpose of the generalization of the results, it is preferred to examine the case using non‐dimensional equations. The lubricant film thickness and pressure distribution before and after the deformation, the bearing deformation and the thrust load‐carrying capacity have been computed and compared for the steel runner‐steel pad and the steel runner‐bronze pad material pairs.Findings – It is found that maximum load capacity loss occurs in the steel runner‐bronze pad pair as 3.03 per cent. Also, for a fixed load, when bearing dimensions are sma.
Improved operation of water distribution systems using variable-speed pumps

Variable-speed pumps are becoming increasingly commonplace in the water distribution industry, replacing conventional fixed-speed pumps. While the principal benefit is reduced energy consumption and power costs, there are other significant advantages, including reduced leakage. This paper focuses on some of the economic and hydraulic benefits of using variable-speed pumps to improve the operation of water distribution systems, by presenting several examples that are intended to emphasize calculated results illustrating these benefits. In particular, a direct calculation of pump speeds to meet desired operating conditions exactly, a determination of optimal pump speeds for the most energy-efficient operation of water distribution systems, and an illustration of controlling potentially damaging transients are presented. These examples make use of a state-of-the-art optimization method based on genetic algorithms, along with the recent advances in hydraulic modeling technology.
Numerical Analysis and Validation of the Rotor Blade Vibration Response Induced by High Pressure Compressor Deep Surge

The following paper presents a numerical analysis of a deep surge cycle of a 4.5 stage research compressor. The resulting unsteady loads are used to determine the response of two particular rotor blade rows that are then compared to strain gauge data from measurements. Within a deep surge cycle the compressor experiences a rapid change of the flow field from forward to reversed flow. This rapid breakdown is linked to a new mean blade load. Hence, the rapid change in blade loads are able to excite fundamental blade modes similar to an impulse load. The resulting vibration magnitudes might reach critical levels. This paper demonstrates two different approaches to evaluate the unsteady flow during a surge cycle.The first uses a three dimensional, time accurate finite volume solver for viscid compressible flows to calculate the transient surge cycle of the compressor. The compressor itself is represented by a multi-blade-row sector model. The second approach makes use of the same solver and compressor domain to determine steady state characteristics of the HPC in forward, stalled and reversed flow. Based on these characteristics an one dimensional finite volume solver for inviscid compressible flows was developed to determine the transient compressor behavior. The one dimensional solver represents the compressor by source terms that are linked to the previously determined steady state characteristics.Copyright © 2014 by Rolls-Royce Deutschland Ltd & Co KG
