Published: December 2019

Abstract
Based on the temperature change and thermal storage processes of PCM phase change energy storage unit, the PCM channel number of which is 39, the plate spacing is 0.01 m, the air channel is 40 with its plate spacing of 0.003 m, and the unit length is total of 1.62 m. MATLAB solution about the above PCM energy storage unit was performed according to the model and physical property data, and the numerical simulation was carried out by using Fluent software. The theoretical calculation and numerical simulation were compared and analyzed. It is found that only in the case of smaller or larger flow rate working conditions, the solution results of MATLAB for the increase rate of the average temperature of the phase change material inside the system is quite different from the FLUENT simulation result; the comparison of the phase change process degree of advancement is found that at a higher flow rate, the difference between the two results is small, but the difference is larger when the flow rate is smaller; the comparison result of the PCM liquid rate is different under the small flow rate condition. However, the comparative analysis of heat storage shows that the maximum error does not exceed 10%. It can be seen that the flow rate conditions in the model and working conditions are the obvious factors affecting the two results, but the calculation and simulation results can more accurately describe the heat storage characteristics of the PCM phase change energy storage unit, which was calculated in nearly 90% ranges of working conditions, which can prove that the results of MATLAB and FLUENT are consistent.

Published: December 2019

Abstract
The failure of high-power DC commutation leads to large fluctuations in the voltage of the transmitting end grid, which brings great harm to the safe and stable operation of the transmitting end grid. In this paper, the detailed analysis of PMU data is carried out for the voltage fluctuation events of the transmitting end caused by the frequent DC commutation failure in recent years. By constructing a simulation model in BPA and RTDS, the fault back-tracking of the voltage fluctuation of the power supply with the commutation failure is carried out. The simulation results show that the main cause of the fluctuation is caused by the timing coordination and the delay of the rectification side AC filter. This is of great significance for reducing voltage fluctuations in the case of subsequent DC system commutation failure, and it also has great significance for maintaining safe and stable operation of the power grid.

Authors: Ravichandran M , Velumani S 
Published: December 2019

Abstract
Facile synthesis of superparamagnetic, highly crystalline, manganese ferrite nanocubes (MnNCs) is reported. X-ray diffraction depicts single-phase face-centred cubic spinel and the electron microscopy represents the nearly monodispersed cube-like nanostructure with the size ranging from 18 to 20 nm. Vibrating sample magnetometer shows magnetization field-dependent curves at 300 K exhibiting the superparamagnetic behaviour of NCs with negligible remanence. Furthermore, the biocompatibility of NCs was proved by MTT assay. These unique characteristics make this NCs as a contrast agent ideally suited for T2-weighted MR imaging. This novel method of synthesizing NCs proves to be very attractive for various biomedical applications because of their outstanding stability and biocompatibility.

Published: December 2019

Abstract
ZnO nanorod arrays (ZnO NRAs) coupled with coral-like CuO nanostructures (CuO CLNs) were prepared by low-temperature hydrothermal method. Self-powered ultraviolet (UV) photodetectors (PDs) based on ZnO NRAs/CuO CLNs/p-GaN heterostructure were fabricated via a direct-contact method. Under UV illumination (1.46 mW cm−2), the ratios of photocurrent to dark current (I
photo/I
dark), photo-responsivity and specific detectivity for the ZnO NRAs/CuO CLNs/p-GaN heterojunction self-powered PD were estimated to be 1143, 1.44 mA W−1 and 5.9 × 1010 cm H z 1 /2/W at 0 V, which were about ∼187, ∼104 and ∼153 times greater than those of the ZnO NRAs/p-GaN self-powered PD, respectively. Moreover, the PD displayed faster response time, excellent stability and repeatability by coupling with CuO CLNs. The mechanism of the enhanced photoresponse performance was discussed through the energy band diagram.

Published: December 2019

Abstract
Room temperature gas sensing behavior of arrayed one-dimensional (1D) nickel nanowires (Ni NWs) are investigated using impedance spectroscopy. Ni nanowires synthesized via electrochemical deposition method based on anodic aluminum oxide (AAO) templates. Their structural characterization verified by scanning electron microscopy (SEM), x-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR) analysis. Impedance spectroscopy as an essential technique utilized to understand the mechanism of gas interaction with the wires through the changes in their electronic behavior. Bode and Nyquist plots with the real and imaginary impedances are plotted versus frequency range of 500 Hz to 2 MHz at different relative humidity values (varying from 30% to 70%) and ethanol vapor concentrations (varying from 2 to 18 ppm). The equivalent circuits are proposed and simulated for impedance responses to both humidity and ethanol vapors. The impedance plots indicate the increase in resistance of the aligned nanowires at low frequencies by the adsorption of water and ethanol molecules.

Use of the ACTH challenge test to identify the predominant glucocorticoid in the southern sea otter (Enhydra lutris nereis)
Authors: Murray M J , Young M A , Santymire R M 
Published: December 2019

Abstract
After nearly being hunted to extinction during the fur trade of the late 20th Century, sea otter (Enhydra lutris) populations have recovered to varying degrees of their historical range. While overall population numbers and range have increased, there are regions in which expansion has occurred at a slower rate and/or animal numbers have decreased, which may be a result of chronic stress from a variety of sources. Some have employed glucocorticoid analysis in their attempts to validate these explanations. Our goal was to conduct a controlled study using sea otters managed under human care to validate the use of serum glucocorticoid analysis to monitor stress physiology in the sea otter. We used a standard ACTH challenge test to compare cortisol and corticosterone responses, thereby identifying the primary glucocorticoid in the sea otter. Fourteen sea otters of both sexes (five males, nine females), including juveniles, sub-adults and adults, participated in the study. The results of the testing supported cortisol as the primary glucocorticoid in the sea otter. Sex and age did not affect how the individual responded to the ACTH or saline injection. Interestingly, the saline injection not only confirmed the effects of the ACTH on glucocorticoid release from the adrenal glands but also provided information on how long it takes the sea otter’s glucocorticoid levels to return to baseline after capture and sedation. The insight gained from this study will aid in future efforts to better understand the role of stress in free-ranging sea otter populations. Recognition of the primary glucocorticoid will facilitate evaluation of more stable biological material, such as fur or whiskers, which tend to be less affected by the diurnal cycling of glucocorticoids.
Electoral Accountability and Responsive Democracy
Authors: Duggan John , Martinelli César 
Published: December 2019

AbstractWe consider elections with hidden preferences and hidden actions, in which neither voters nor politicians can commit to future choices. When politicians are highly office motivated, they respond by choosing high policies to signal that they are above average, and some below-average politicians must randomise between choosing policies near their ideal points and mimicking above-average politicians by choosing high policies. If voter preferences are increasing, then elections deliver positive outcomes; but if voter preferences are single peaked, then politicians overshoot in the first period. Electoral incentives shift to sanctioning, rather than selection, as office motivation becomes large.

Authors: Böhm Michael , Coats Andrew J S , Kindermann Ingrid , Spoletini Ilaria , Rosano Giuseppe 
Published: December 2019

Abstract
Comorbidities are increasingly recognized as crucial components of the heart failure syndrome. Main specific challenges are polypharmacy, poor adherence to treatments, psychological aspects, and the need of monitoring after discharge. The chronic multimorbid patient therefore represents a specific heart failure phenotype that needs an appropriate and continuous management over time. This supplement issue covers the key points of a series of meeting coordinated by the Heart Failure Association of the European Society of Cardiology (ESC), that have discussed the issues surrounding the effective monitoring of our ever more complex and multimorbid heart failure patients. Here, we present an overview of the complex issues from a healthcare delivery perspective.
Earning to learn: the time-health trade-offs of employed Australian undergraduate students
Authors: Grimmond Tessa , Yazidjoglou Amelia , Strazdins Lyndall 
Published: December 2019

AbstractAustralian undergraduate students are facing difficult economic circumstances and rates of psychological distress are well above the general population. Many are combining their study with paid work to manage financially. There is, however, little to no research on the relationship between economic pressures, academic demands and health (mental and physical) among these young adults. This study used a mixed-methods approach, combining semi-structured interviews with health measures to investigate the interactions and interconnections between work, study and health among 22 Australian undergraduate students. Thematic data analysis concentrated on the effect of time constraints on health, due to the financial and academic demands of contemporary undergraduate life. We found that students felt time-pressured, and commonly sacrificed sleep, nutrition, exercise and lecture attendance as a way of managing employment demands. These strategies contributed to poor health; we observed very high rates of psychological distress, poor sleep, diet and exercise, peaking during exams. Our in-depth study illustrates the challenges facing the current generation of undergraduate students in Australia, raising their study–work conflict as a genuine public health and social equity issue.
The Chios Massacre (1822) and early British Christian-humanitarianism
Authors: Cartledge Yianni John Charles 
Published: December 2019

Abstract
This article explores early British Christian-humanitarianism towards the Greeks following the 1822 Chios Massacre. Scholars of the Greek revolution have previously acknowledged the massacre as a pivotal moment for British attitudes towards the Greeks, although few have elaborated significantly on this humanitarian shift. This article focuses on what the massacre was and public and political reactions to it in Britain. It also investigates how perceptions of ‘Christian’ Greeks, compared to ‘Islamic’ and ‘barbarian’ Ottomans, encouraged British sympathy. Essentially it argues that the massacre ‘humanized’ the Greeks to the British, leading to an early type of Christian-humanitarian intervention.
Gastroenterologist Consultation Is Uncommon but Associated with Improved Care Among IBD Patients Presenting to Emergency Departments in Winnipeg Hospitals
Authors: Bernstein Charles N , Crocker Elise , Nugent Zoann , Virdi Paramvir , Singh Harminder , Targownik Laura E 
Published: December 2019

Abstract

Objective
To describe the patterns of care when persons with inflammatory bowel disease (IBD) present to the Emergency Department (ED) and post-ED follow-up.

Methods
We linked the University of Manitoba IBD Epidemiology Database with the Emergency Department Information System of the Winnipeg Regional Health Authority from January 1, 2010 to December 31, 2012. We then generated a list of all ED attendances by persons with IBD at four of six hospitals within the City of Winnipeg (two academic and two community hospitals). The charts were reviewed by two investigators extracting data on testing, consulting and treatment undertaken in the ED as well as postdischarge follow-up. We focused on outcomes among those attending the ED but not admitted to hospital.

Results
Of 1275 IBD patients with a first visit to the ED, 523 (41%) were for IBD-specific complaints. Three hundred and twenty-seven (62.5%) were discharged from the ED without an in-hospital admission. Nearly 80% had an identified gastrointestinal (GI) specialist (either gastroenterologist or GI surgeon) involved in their care. A gastroenterologist was consulted in the ED 20% of the time. Follow-up post-ED with a gastroenterologist was only documented in 36%. For those who saw a gastroenterologist in the ED, there was more likely to be a change in medications and follow-up arranged with a gastroenterologist. ED consultation with a gastroenterologist was the only predictor of seeing a gastroenterologist in follow-up post-ED.

Conclusions
ED gastroenterology consultation is more likely to effect IBD management change. When discharged from the ED gastroenterology, follow-up should be arranged and documented.
Predicting oil saturation of tight conglomerate reservoirs via well logs based on reconstructing nuclear magnetic resonance T2 spectrum under completely watered conditions

Published: December 2019

Abstract
Due to complex lithology, strong heterogeneity, low porosity and permeability; resistivity logging faces great challenges in oil saturation prediction of tight conglomerate reservoirs. First, 10 typical core samples were selected to measure and analyse the porosity, permeability, nuclear magnetic resonance (NMR) T2 spectrum and mercury injection capillary pressure (MICP) curve. Second, an empirical method was proposed for reconstructing the NMR T2 spectrum under completely watered conditions using MICP curve based on the ‘three-piece’ power function. The parameters of different models were calibrated via experimental data analysis, respectively. The 180 core experimental data from an MICP curve were used as the input database. Porosity and permeability were regarded as the MICP data selection criteria to apply this model in formation evaluation. The comparison results show good application effects. Finally, to reflect oil saturation, the ratio of T2 geometric means of NMR T2 spectra under oil-bearing and completely watered conditions was proposed. Then, the quantitative relation between oil saturation and the proposed ratio was established via experimental data from the sealed cores, which established a quantitative prediction on oil saturation of tight conglomerate reservoirs. This showed a good application effect. The average relative error and the root mean square error (RMSE) of the predicted oil saturation and sealed coring measurement were around 10 and 3%, respectively. As the proposed method is only influenced by the wettability of reservoir and viscosity of oil, it is not only appropriate for the studied area, but also for other water-wet reservoirs containing light oil. It is important for identifying oil layers, calculating oil saturation and improving log interpretation accuracy in tight conglomerate reservoirs.
Iatrogenic rectal injury associated with fleet enema administration masquerading as Fournier’s Gangrene
Authors: Liang Yi , Di Re Angelina , Ctercteko Grahame 
Published: December 2019

Abstract
Rectal injuries secondary to fleet enemas are the result of a chemical irritation as well as mechanical trauma causing localized perforation and mucosal necrosis. These injuries can be managed expectantly. Fournier’s Gangrene is a life-threatening, fulminant soft tissue infection of the genito-perineal region commonly secondary to a perianal infection, requiring extensive debridement of all affected tissue and judicious antibiotic therapy. This distinction is critical in the management of the current case, allowing for limited debridement and judicious observation without a resection of the injured rectum. A diverting colostomy allows for effective faecal management and minimizes contamination of the perineal wound.
Reduced Translational Efficiency of Eukaryotic Genes after Duplication Events
Authors: Chang Andrew Ying-Fei , Liao Ben-Yang 
Published: December 2019

AbstractControl of gene expression has been found to be predominantly determined at the level of protein translation. However, to date, reduced expression from duplicated genes in eukaryotes for dosage maintenance has only been linked to transcriptional control involving epigenetic mechanisms. Here, we hypothesize that dosage maintenance following gene duplication also involves regulation at the protein level. To test this hypothesis, we compared transcriptome and proteome data of yeast models, Saccharomyces cerevisiae and Schizosaccharomyces pombe, and worm models, Caenorhabditis elegans and Caenorhabditis briggsae, to investigate lineage-specifically duplicated genes. Duplicated genes in both eukaryotic models exhibited a reduced protein-to-mRNA abundance ratio. Moreover, dosage sensitive genes, represented by genes encoding protein complex subunits, reduced their protein-to-mRNA abundance ratios more significantly than the other genes after duplication events. An analysis of ribosome profiling (Ribo-Seq) data further showed that reduced translational efficiency was more prominent for dosage sensitive genes than for the other genes. Meanwhile, no difference in protein degradation rate was associated with duplication events. Translationally repressed duplicated genes were also more likely to be inhibited at the level of transcription. Taken together, these results suggest that translation-mediated dosage control is partially contributed by natural selection and it enhances transcriptional control in maintaining gene dosage after gene duplication events during eukaryotic genome evolution.
Induced illusory body ownership in borderline personality disorder

Published: December 2019

Abstract
One aspect of selfhood that may have relevance for borderline personality disorder (BPD) is variation in sense of body ownership. We employed the rubber hand illusion to manipulate sense of body ownership in BPD. We extended previous research on illusory body ownership in BPD by testing: (i) two illusion conditions: asynchronous and synchronous stimulation, (ii) relationship between illusion experience and BPD symptoms, and (iii) relationship between illusion experience and maladaptive personality traits. We measured illusion strength (questionnaire responses), proprioceptive drift (perceived shift in physical hand position), BPD symptoms (Revised Diagnostic Interview for Borderlines score), and maladaptive personality traits (Personality Inventory for DSM-5) in 24 BPD and 21 control participants. For subjective illusion strength, we found main effects of group (BPD &gt; healthy control, F(1, 43) = 11.94, P = 0.001) and condition (synchronous &gt; asynchronous, F(1, 43) = 22.80, P &lt; 0.001). There was a group × condition interaction for proprioceptive drift (F(1, 43) = 6.48, P = 0.015) such that people with BPD maintained illusion susceptibility in the asynchronous condition. Borderline symptom severity correlated with illusion strength within the BPD group, and this effect was specific to affective (r = 0.45, P &lt; 0.01) and cognitive symptoms (r = 0.46, P &lt; 0.01). Across all participants, trait psychoticism correlated with illusion strength (r = 0.44, P &lt; 0.01). People with BPD are more susceptible to illusory body ownership than controls. This is consistent with the clinical literature describing aberrant physical and emotional experiences of self in BPD. A predictive coding framework holds promise to develop testable mechanistic hypotheses for disrupted bodily self in BPD.
