Published: September 2022

AbstractThe present study is on the fabrication of epoxy nanocomposites for electromagnetic interference (EMI) shielding in the X‐band and Ku‐band frequency range. Single‐layer unidirectional carbon fiber along with nano zirconia is used to achieve the required EMI shielding and mechanical strength. The microstructural study of the fabricated samples has revealed the good lamination of carbon fiber in epoxy matrix and the uniform dispersion nanoparticles provide a reduction of wettability. Dielectric parameter studies indicate an increase in permittivity and dielectric loss with the addition of zirconia nanoparticles. The shielding effectiveness (SE) shows as high as 25 dB when the electric field is parallel with the carbon fiber orientation. The addition of zirconia nanoparticles to the carbon fiber reinforced epoxy composite have enhanced the ability of microwave absorption shielding. Mechanical properties of the epoxy carbon fiber nano zirconia composites show an improvement in storage modules, activation energy, and impact resistance. It is realized that 3 wt% zirconia added epoxy carbon fiber composite shows high shielding effectiveness with good mechanical properties.
A note on a performance recovery method for a class of nonaffine‐in‐control nonlinear systems with input saturation
Authors: Yang Hao , Pei Hailong , Cen Jian 
Published: September 2022

AbstractThis article proposes a feasible method for a class of nonaffine‐in‐control nonlinear systems in the presence of input saturation to obtain performance recovery. In the previous work, the plant is required to be affine‐in‐control to derive the difference between the desired and saturated inputs. Considering the nonaffine structure, we first build a fast subsystem with respect to the nominal system, where no saturation is presented. Then, an intermediate subsystem is established to compensate the influence of input saturation by approximating the difference between the original and nominal systems. In the slow time‐scale, a series of existing control methods can be combined to achieve the requested transient performance. The ability of performance recovery is proved rigorously by the singular perturbation theory. Numerical examples are illustrated to demonstrate the validity of the presented method.
The Risk of Osteopenia/Osteoporosis and Psoriatic Disease: A Systematic Review
Authors: Schauer Anna , Uthayakumar Aarthy K. , Boardman Glenn , Bunker Christopher B. 
Published: September 2022

Abstract

Background
Psoriasis (Ps) is a multisystem inflammatory disease associated with several comorbidities; however, its effect on bone health remains uncertain. This systematic review aimed to evaluate the risks of osteopenia (OPe) and osteoporosis (OP) in psoriasis.

Methods
A systematic search was performed for published studies evaluating cutaneous Ps and psoriatic arthritis (PsA) compared with healthy control groups utilizing a validated bone mineral density (BMD) assessment score. Meta-analysis was performed using a random-effects model; pooled estimates and their confidence intervals (CIs) were calculated. For analysis, Ps and PsA groups were combined due to the small number of studies.

Results
Twenty-one studies were included for final analysis; three Ps only, 15 PsA and three both. There was a significant difference between psoriatic disease (combination Ps and PsA group) compared with controls relating to an association with OP/OPe, with an overall odds ratio (OR) of 1.71 (95% CI 1.07–2.74: p-value = 0.026). The Ps group had significantly lower BMD than the control group at both the lumbar spine and femoral neck (mean difference −0.04; 95% CI −0.090 to 0.002 and −0.03; 95% CI −0.059 to 0.003 respectively).

Conclusion
Putative risks of OPe and OP in both Ps and PsA are supported but not confirmed. Significant heterogeneity of reported data limits definitive conclusions in this meta-analysis. This review contributes to the further understanding of Ps as a multisystem disease and future management of potential comorbidities, but highlights key gaps in the literature. Further studies addressing standardised OP reporting, specific disease group characteristics comparing Ps with PsA, patient characteristics and medication use, are required in order to make more certain conclusions with greater clinical impact.

AbstractA question title's function is to generate readable titles and describe a problem encountered by the code. Previous studies often used an end‐to‐end sequence‐to‐sequence system to generate question title's from source code. However, long‐term dependencies are often difficult to capture, and this may result in an incomplete source code representation. To address this issue, we propose a Transformer for Generating Code Title (hereinafter referred to as TGCT) model. Specifically, the TGCT model uses the position coding mechanism to model paired relationships between source terms by applying relative position representations. Multiple self‐attention mechanism components are also used to capture long‐term dependencies of the code. Comprehensive experiments on datasets from five coding languages, namely Python, Java, JavaScript, C#, and SQL, are conducted, and the results show that TGCT outperforms state‐of‐the‐art models based on the measurements of BLEU and ROUGE in general. In addition, a cross‐sectional comparison experiment was conducted to verify the effects of different model parameters, different data set sizes, position coding mechanism, and self‐attention mechanism on model results.
Anaesthetic management in a dog with constrictive pericarditis complicated with bi‐atrial enlargement and atrial fibrillation undergoing subtotal pericardiectomy
Authors: Parra Martínez Cristina , Charlesworth Tim M. , Francis Andrew 
Published: September 2022

AbstractA 2‐year 8‐month‐old female dobermann presented for a recheck after previous crown reduction and vital pulp therapy. On cardiac auscultation, rapid and irregularly irregular heart rhythm and irregular and asynchronous pulses were detected. On electrocardiogram and transthoracic echocardiogram, findings were suggestive of constrictive pericarditis complicated with bi‐atrial enlargement and atrial fibrillation. Subtotal pericardiectomy was performed. The patient was premedicated with methadone (0.2 mg/kg intravenously), and anaesthesia was induced with midazolam (0.2 mg/kg intravenously) and propofol (60 mg), and maintained with isoflurane in oxygen. Constant‐rate infusions of fentanyl (0.1–0.2 µg/kg/min) and lidocaine (50 µg/kg/min) were administered. Dobutamine (1–5 µg/kg/min) helped to maintain mean arterial blood pressure above 65 mmHg. Fluid resuscitation and noradrenaline infusion (0.1 µg/kg/min) started after constriction was released to optimise preload. Haemodynamic support and ventricular rate control continued during the immediate postoperative period. Recovery from general anaesthesia was uneventful.

Published: September 2022

AbstractA novel equine multi‐modal protocol was implemented for management of unilateral equine dry eye disease and worsening persistent epithelial defects in a clinically well Irish Sports Horse. Utilising knowledge directly from human ophthalmic medicine for meibomian gland dysfunction, the meibomian glands were first mechanically debrided and expressed. Then a four‐point treatment protocol was instigated. The protocol comprised hot compressing, artificial tears, autologous serum and a topical azithromycin regimen, resulting in a significant improvement in persistent epithelial defects and clinical signs. This case highlights the benefits of a treatment plan containing both non‐pharmacological and pharmacological therapies targeting the lipid component of the tear film matrix in horses with dry eye disease.
A Model for the Asymmetry
Authors: Grandjean Vincent 
Published: September 2022

AbstractAs has been argued, there are good reasons to think that, assuming physical indeterminism, the asymmetry between the ‘open future’ and the ‘fixed past’ is to be characterized as a kind of worldly unsettledness: there being facts of the matter about what happened, but not about what will happen. However, the main models of the temporal structure of the world – eternalism and presentism – do not reflect any ontological asymmetry between the future and the past. According to these models, either both the future and the past exist, or neither the future nor the past exists. So, in this chapter, I argue that we should opt for an alternative model of the temporal structure of the world – the growing block theory (GBT) – that seems better designed to accommodate the asymmetry in openness between the future and the past.
Introduction: The European Paradox of Expecting Corrupt Political Elites to Lead the Fight Against Corruption
Authors: Martin-Russu Luana 
Published: September 2022

AbstractMartin-Russu starts her analysis from an empirical puzzle: Romania’s abrupt shift from observing European norms and standards, towards increasingly diverging from them after having gained full EU membership. Romania’s pre-accession drive to curb corruption, very much aligned with the EU’s requirements, contrasts with the state’s post-accession backslide and the gradual deterioration of already adopted public integrity reforms.The introduction sets the basis for discussion by arguing that in contexts corroded by high-level corruption, claims of successful Europeanization, particularly in the area of public integrity, are highly counter-intuitive. The priority attached by the EU to the rule of law and justice reform can hardly eliminate the fundamental incentive for political corruption. A self-serving political elite remains unable to genuinely commit to the implementation of substantial anti-corruption reforms.

Islam-/Muslim*innenfeindlichkeit als Gegenstand empirischer Sozialforschung
Authors: Diekmann Isabell 
Published: September 2022

ZusammenfassungNachdem im vorangegangen Kapitel die Relevanz unterschiedlicher, insbesondere quer zueinander verlaufender Kategorisierungen aufgezeigt wurde, widmet sich dieses Kapitel Konjunkturen von Kategorisierungen und Begrifflichkeiten im Zusammenhang mit Islam und Muslim*innen sowie feindlichen und abwertenden Einstellungen, Verhaltensweisen und Strukturen ihnen gegenüber. Obwohl viele Muslim*innen bereits in den 1960er Jahren nach Deutschland migrierten, war die Kategorie Muslim*in bis in die 1990er Jahre hinein kaum von Bedeutung. Auch die wissenschaftliche Bearbeitung der Konzepte Islam-/Muslim*innenfeindlichkeit und antimuslimischer Rassismus fand zuvor kaum statt.
Climate change impacts on thermal stress in four climatically diverse European cities

Published: September 2022

AbstractThe thermal conditions that prevail in cities pose a number of challenges to urban residents and policy makers related to quality of life, health and welfare as well as to sustainable urban development. However, the changes in thermal stress due to climate change are probably not uniform among cities with different background climates. In this work, a comparative analysis of observed and projected thermal stress (cold stress, heat stress, no thermal stress) across four European cities (Helsinki, Rotterdam, Vienna, and Athens), which are representative of different geographical and climatic regions of the continent, for a recent period (1975 − 2004) and two future periods (2029 − 2058, 2069 − 2098) has been conducted. Applying a rational thermal index (Universal Thermal Climate Index) and considering two models of the EURO-CORDEX experiment (RCA4-MOHC, RCA4-MPI) under two Representative Concentration Pathways (RCP4.5, RCP8.5), the projected future changes in thermal conditions are inspected. The distribution of thermal stress in the current climate varies greatly between the cities, reflecting their climatic and urban heterogeneity. In the future climate, a reduction in the frequency of cold stress is expected across all cities, ranging between − 2.9% and − 16.2%. The projected increase in the frequency of optimal thermal conditions increases with increasing latitude, while the projected increase in the frequency of heat stress (ranging from + 0.2 to + 14.6%) decreases with increasing latitudes. Asymmetrical changes in cold- and heat-related stress between cities were found to affect the annual percentage of optimal (no thermal stress) conditions in future. Although future projections are expected to partly bridge the gap between the less-privileged cities (with respect to annual frequency of optimal thermal conditions) like Helsinki and Rotterdam and the more privileged ones like Athens, the former will still lag behind on an annual basis.
Ethical Decision-Making in Indigenous Financial Services: QSuper Case Study

Published: September 2022

AbstractThis case study details how and why integrating storytelling, empathy, and inclusive practice shifted QSuper, a large Australian finance organisation, from minimal awareness to moral awareness then moral capability in the delivery of services to Indigenous customers. During the Royal Commission into Misconduct in the Banking, Superannuation, and Financial Services Industry, QSuper were recognised for their exemplary service with Indigenous customers (Hayne, Interim report: Royal commission into misconduct in the banking, superannuation and financial services industry, Volume 1. Commonwealth of Australia, 2018;Transcript of Proceedings, 13 August, Commonwealth of Australia, 2018). This position was in stark contrast to the inaccessible service offerings of other financial organisations where some used predatory practices to sell unethical financial products to Indigenous Australians (Hayne, Interim report: Royal commission into misconduct in the banking, superannuation and financial services industry, Volume 1. Commonwealth of Australia, 2018; Hayne, Final report: Royal commission into misconduct in the banking, superannuation and financial services industry, Volume 1. Commonwealth of Australia, 2019a). Storytelling garned from visiting customers in remote communities and other meaningful activities involving inclusive practice to facilitate ethical decision-making in finance is different to standard functionalist finance approaches (Schinckus, Int Rev Financ Anal 40:103–106, 2015). Two empathetic questions asked within QSuper complementing the storytelling, were: “What is the right thing to do by the customer?” and “How would I feel if this were my mother?” Exploration into the lived reality of moral capacity is important based on the Commission finding many of the 490,000 finance staff do not know how to provide ethical services to vulnerable customers, in particular remote Indigenous customers (Australian Bureau of Statistics. Labour force, Australia, detailed. ABS. Retrieved fromhttps://www.abs.gov.au/statistics/labour/employment-and-unemployment/labour-force-australia-detailed/latest-release, 2021; Hayne, Final report: Royal commission into misconduct in the banking, superannuation and financial services industry, Volume 1. Commonwealth of Australia, 2019a). Furthermore, there is minimal literature on the role of Indigenous storytelling to heighten moral awareness in the finance industry which was found to lead to better ethical outcomes.
Exploring the effectiveness of demand-side retail pharmaceutical expenditure reforms

Published: September 2022

AbstractIncreasing expenditures on retail pharmaceuticals bring a critical challenge to the financial stability of healthcare systems worldwide. Policy makers have reacted by introducing a range of measures to control the growth of public pharmaceutical expenditure (PPE). Using panel data on European and non-European OECD member countries from 1990 to 2015, we evaluate the effectiveness of six types of demand-side expenditure control measures including physician-level behaviour measures, system-level price-control measures and substitution measures, alongside a proxy for cost-sharing and add a new dimension to the existing empirical evidence hitherto based on national-level and meta-studies. We use the weighted-average least squares regression framework adapted for estimation with panel-corrected standard errors. Our empirical analysis suggests that direct patient cost-sharing and some—but not all—demand-side measures successfully dampened PPE growth in the past. Cost-sharing schemes stand out as a powerful mechanism to curb PPE growth, but bear a high risk of adverse effects. Other demand-side measures are more limited in effect, though may be more equitable. Due to limitations inherent in the study approach and the data, the results are only explorative.

Published: September 2022

AbstractThe bedside Exhaled Drug MONitor – EDMON measures exhaled propofol in ppbv every minute based on multi-capillary column – ion mobility spectrometry (MCC-IMS). The MCC pre-separates gas samples, thereby reducing the influence of the high humidity in human breath. However, preliminary analyses identified substantial measurement deviations between dry and humid calibration standards. We therefore performed an analytical validation of the EDMON to evaluate the influence of humidity on measurement performance. A calibration gas generator was used to generate gaseous propofol standards measured by an EDMON device to assess linearity, precision, carry-over, resolution, and the influence of different levels of humidity at 100% and 1.7% (without additional) relative humidity (reference temperature: 37°C). EDMON measurements were roughly half the actual concentration without additional humidity and roughly halved again at 100% relative humidity. Standard concentrations and EDMON values correlated linearly at 100% relative humidity (R²=0.97). The measured values were stable over 100min with a variance ≤ 10% in over 96% of the measurements. Carry-over effects were low with 5% at 100% relative humidity after 5min of equilibration. EDMON measurement resolution at 100% relative humidity was 0.4 and 0.6 ppbv for standard concentrations of 3 ppbv and 41 ppbv. The influence of humidity on measurement performance was best described by a second-order polynomial function (R²≥0.99) with influence reaching a maximum at about 70% relative humidity. We conclude that EDMON measurements are strongly influenced by humidity and should therefore be corrected for sample humidity to obtain accurate estimates of exhaled propofol concentrations.

AbstractA new hybrid polarization division multiplexing (PDM) spectral amplitude coding optical code division multiple access (SAC-OCDMA) is proposed for free space optical (FSO) for capacity enhancement. Two polarization signals are utilized; one is x-polarization and carries three different channels at 0° azimuthal angle while the other is y-polarization at 90° azimuthal angle, and carries the same three channels. Each channel is assigned with a diagonal permutation shift (DPS) code and carries 10 Gbps. The suggested system is simulated, and its performance is evaluated in terms of maximum allowable number of users, propagation range, bit error rate (BER), Q-factor, and received power for the different channels under various fog, dust storm, and rain scenarios. The reported results indicate that the system can support a signal travelling up to 2, 0.9, and 1.3 km, respectively, under light fog (LF), light dust (LD), and light rain (LR). As the level of these weather conditions is increased from light to moderate, the FSO link length decreases to 1.3, 0.25, and 1.8 km under medium fog (MF), medium dust (MD), and medium rain (MR), respectively. Furthermore, the shortest propagation range is achieved as the level of weather conditions becomes heavy, where the FSO link range becomes 1, 0.095, and 1.1 km under heavy fog (HF), heavy dust (HD), and heavy rain (HR), respectively. All these ranges are considered at BER ≤ 10–3and a received power ≤ − 27 dBm with 60 Gbps overall data transmission. This new hybrid FSO system is suggested to be implemented in desert areas that affects by dust storms and in 5G wireless transmission communications.
Uncovering the link between intra-individual heterogeneity and variety seeking: the case of new shared mobility
Authors: Song Fangqing , Hess Stephane , Dekker Thijs 
Published: September 2022

AbstractPreferences can vary both across respondents (i.e. inter-respondent preference heterogeneity) and across choice tasks within respondents (i.e. intra-respondent preference heterogeneity). Ignoring the existence of intra-respondent preference heterogeneity could bias preference elicitation and demand forecast. Thus far, most studies covering inter- and intra-respondent preference heterogeneity have applied the mixed multinomial logit model. Meanwhile, the behavioural explanations for such preference variations remain under-explored. This paper accommodates inter- and intra-respondent preference heterogeneity through a two-layer latent class modelling structure, where the continuous random distributions are replaced with discrete mixtures in both layers. A latent variable representing variety-seeking is included to explain class membership probabilities, offering additional behavioural insights concerning the source of preference heterogeneity both across and within respondents. Two aspects associated with variety-seeking are examined: novelty-seeking (i.e. the inclination to adopt new modes) and alternation (i.e. the tendency to vary one’s behaviour regularly by selecting different modes continuously). In the context of new shared mobility, this paper finds the role of both aspects in preference heterogeneity. Specifically, novelty seekers are found to be more likely to fall into the class with higher probabilities of switching from existing modes to the new air taxi service than novelty avoiders, and alternation seekers are more likely to belong to the class with higher probabilities to exhibit intra-respondent preference heterogeneity than alternation avoiders. This paper, therefore, provides empirical evidence to identify the target customers of the new air taxi service.
