The Relationship Between Illusory Crescents and the Stream/Bounce Effect
Authors: A-Izzeddin Emily J. , Grove Philip M. 
Published: April 2021

Abstract
We conducted two experiments to evaluate Meyerhoff and Scholl’s (2018, Cognition 170, 88–94) hypothesis that illusory crescents contribute to resolutions in audiovisual stream/bounce displays. In Experiment 1, we measured illusory crescent size in the launching effect as a function of speed, overlap, and sound. In Experiment 2, we tabulated stream and bounce responses to similar stimuli with the same speed, sound, and overlap conditions as Experiment 1. Our critical manipulation of target speed spanned the range of values from typical stream/bounce investigations of ∼5 degrees/s up to the target speeds employed by Meyerhoff and Scholl ∼38 degrees/s. We replicated Meyerhoff and Scholl’s findings at higher speeds, but not at slower speeds. Critically, we found that speed influenced crescent size judgements and bouncing responses in opposite directions. As target speed increased, illusory crescent size increased (Experiment 1), but the overall percentage of bounce responses decreased (Experiment 2). Additionally, we found that sound failed to enhance illusory crescent size at slower speeds but promotes bouncing responses at all speeds. The disassociation of the effects of speed and sound on illusory crescents with those effects on reported streaming/bouncing in similar displays provides compelling evidence against Meyerhoff and Scholl’s hypothesis. Therefore, we conclude that illusory crescents do not account for the pattern of responses attributed to the stream/bounce effect.
Sterilizing Pregnant Companion Animals: Ethics and Law
Authors: Paterson Mandy B.A. , Jamieson Philip 
Published: April 2021

Abstract
Although the sterilization of pregnant companion animals occurs regularly in private veterinary clinics and animal shelters, there is growing concern amongst veterinarians and animal welfare supporters about the appropriateness of carrying out this procedure. The ethical and legal perspectives of the procedure have not been widely discussed in the available literature. This paper aims to remedy this situation. It considers the sterilization of pregnant companion animals using four ethical frameworks: animal rights, utilitarian, relational and contractarian. The possible interests of all involved parties, including the animal itself, the unborn young, the veterinarian, shelter and clinic staff, and the wider community are included. Where the science on companion animals in this area is limited, the paper draws on science involving other species. The legal aspects are discussed with analogies to human abortion laws. The paper concludes by providing a framework that veterinarians and others can use when making ethical decisions.
Locating the Non-Aḥrārī Silsila of the Naqshbandīya in Central Asia: A Historical Contextualization of Ḥāfiẓ Baṣīr within the Central Asian Sufi Tradition
Authors: Shanazarova Aziza 
Published: April 2021

Abstract
The aim of the paper is twofold. Firstly, to provide a historical contextualization of Ḥāfiẓ Baṣīr, the author of the Maẓhar al-‘ajā’ib (circa 973/1565), within the Central Asian Sufi tradition based on historical and hagiographical sources from the 16th to the 18th centuries. Secondly, to locate the non-Aḥrārī silsila of the Naqshbandīya in Central Asia passing through Ḥāfiẓ Baṣīr that survived in the region of Khwarazm until the second half of the 18th century.
Knowing What to Do Substantially Improves the Effectiveness of Flood Early Warning
Authors: Kreibich Heidi , Hudson Paul , Merz Bruno 
Published: April 2021

AbstractFlood warning systems are longstanding success stories with respect to protecting human life, but monetary losses continue to grow. Knowledge on the effectiveness of flood early warning in reducing monetary losses is scarce, especially at the individual level. To gain more knowledge in this area, we analyze a dataset that is unique with respect to detailed information on warning reception and monetary losses at the property level and with respect to amount of data available. The dataset contains 4,468 loss cases from six flood events in Germany. These floods occurred between 2002 and 2013. The data from each event were collected by computer-aided telephone interviews in four surveys following a repeated cross-sectional design. We quantitatively reveal that flood early warning is only effective in reducing monetary losses when people know what to do when they receive the warning. We also show that particularly long-term preparedness is associated with people knowing what to do when they receive a warning. Thus, risk communication, training, and (financial) support for private preparedness are effective in mitigating flood losses in two ways: precautionary measures and more effective emergency responses.
The power distribution between symmetric and anti-symmetric components of the tropical wavenumber-frequency spectrum

Published: April 2021

AbstractA yet unexplained feature of the tropical wavenumber-frequency spectrum is its parity distributions, i.e., the distribution of power between the meridionally symmetric and anti-symmetric components of the spectrum. Due to the linearity of the decomposition to symmetric and anti-symmetric components and the Fourier analysis, the total spectral power equals the sum of the power contained in each of these two components. However, the spectral power need not be evenly distributed between the two components. Satellite observations and reanalysis data provide ample evidence that the parity distribution of the tropical wavenumber-frequency spectrum is biased towards its symmetric component. Using an intermediate-complexity model of an idealized moist atmosphere, we find that the parity distribution of the tropical spectrum is nearly insensitive to large-scale forcing, including topography, ocean heat fluxes, and land-sea contrast. On the other hand, we find that a small-scale (stochastic) forcing has the capacity to affect the parity distribution at large spatial scales via an upscale (inverse) turbulent energy cascade. These results are qualitatively explained by considering the effects of triad interactions on the parity distribution. According to the proposed mechanism, any bias in the small-scale forcing, symmetric or anti-symmetric, leads to symmetric bias in the large-scale spectrum regardless of the source of variability responsible for the onset of the asymmetry. As this process is also associated with the generation of large-scale features in the Tropics by small-scale convection, the present study demonstrates that the physical process associated with deep-convection leads to a symmetric bias in the tropical spectrum.
Effect of Scale-Aware Planetary Boundary Layer Schemes on Tropical Cyclone Intensification and Structural Changes in the Gray Zone

Published: April 2021

AbstractHorizontal grid spacings of numerical weather prediction models are rapidly approaching O (1 km) and have become comparable with the dominant length scales of flows in the boundary layer; within such “gray-zone”, conventional planetary boundary layer (PBL) parameterization schemes start to violate basic design assumptions. Scale-aware PBL schemes have been developed recently to address the gray-zone issue. By performing WRF simulations of Hurricane Earl (2010) at sub-kilometer grid spacings, this study investigates the effect of the scale-aware Shin-Hong (SH) scheme on the tropical cyclone (TC) intensification and structural changes in comparison to the non-scale-aware YSU scheme it is built upon. Results indicate that SH tends to produce a stronger TC with a more compact inner core than YSU. At early stages, the scale-aware coefficients in SH gradually decrease as the diagnosed boundary layer height exceeds the horizontal grid spacing. This scale-aware effect is most prominent for the nonlocal subgrid-scale vertical turbulent fluxes, in the non-precipitation regions radially outside of the convective rainband, and from the early stage through the middle of rapid intensification (RI) phase. Both the scale awareness and different parameterization of the nonlocal turbulent heat flux in SH reduce the parameterized vertical turbulent mixing, which further induces stronger radial inflows and helps retain more water vapor in the boundary layer. The resulting stronger moisture convergence and diabatic heating near the TC center account for the faster inner-core contraction before RI onset and the higher intensification rate during the RI period. Potential issues of applying these two PBL schemes in TC simulations and suggestions for improvements are discussed.

Published: April 2021

AbstractDrought is a complex challenge experienced in specific locations through diverse impacts, including ecological impacts. Different professionals involved in drought preparedness and response approach the problem from different points of view, which means they may or may not recognize ecological impacts. This study examines the extent to which interviewees perceive ecological drought in the Upper Missouri Headwaters basin in southwestern Montana. Through semistructured interviews, this research investigates individuals’ perceptions of drought by analyzing how they define drought, how they describe their roles related to drought, and the extent to which they emphasize ecological impacts of drought. Results suggest that while most interviewees have an integrated understanding of drought, they tend to emphasize either ecological or nonecological impacts of drought. This focus was termed their drought orientation. Next, the analysis considers how participants understand exposure to drought. Results indicate that participants view drought as a complex problem driven by both human and natural factors. Last, the paper explores understandings of the available solution space by examining interviewees’ views on adaptive capacity, particularly factors that facilitate or hinder the ability of the Upper Missouri Headwaters region to cope with drought. Participants emphasized that adaptive capacity is both helped and hindered by institutional, cultural, and economic factors, as well as by available information and past resource management practices. Understanding how interviewees perceive the challenges of drought can shape drought preparedness and response, allowing those designing programs to better align their efforts to the perceptions of their target audience.

Published: April 2021

ObjectiveThis is the first database study to assess the effectiveness of prophylactic preoperative antibiotics (PPAs) in mandible fracture repair.Study DesignRetrospective cohort.SettingDatabase study using US inpatient and outpatient insurance claims submitted from July 2006 to March 2015.MethodsThe IBM MarketScan Commercial Database was queried for adults aged 18 to 64 years who had undergone first‐time mandible fracture repair according to Current Procedural Terminology codes for open and closed repair. Primary outcomes included surgical revision, local infection, and osteomyelitis. Rates were compared between cohorts based on whether or not patients had filled antibiotic prescriptions during the preoperative period alone. The effects of drug abuse and type of mandible repair (open vs closed) were explored. Multivariate Poisson regression models were used to calculate adjusted relative risk estimates, and 95% CIs were used to determine statistically significant differences.ResultsA total of 2676 patients were included, with 847 (31.7%) filling PPAs and 1829 (68.3%) filling no antibiotics. Rates were 38.9% for revision, 5.8% for local infection, and 2.1% for osteomyelitis. After multivariate analysis, exposure to PPAs was not associated with surgical revision (adjusted relative risk, 1.04; 95% CI, 0.94‐1.15), local infection (1.16; 0.82‐1.64), or osteomyelitis (1.21; 0.68‐2.14). Patients were more likely to fill PPAs if they underwent open repair (35.3%) versus closed (26.6%) (proportion difference, 8.7%; 95% CI, 5.2%‐12.2%), but exposure to antibiotics did not predict outcomes on subgroup analysis.ConclusionPPAs do not improve mandible repair outcomes, regardless of repair type.
Risk of COVID‐19 Infection Among Chronic Rhinosinusitis Patients Receiving Oral Corticosteroids
Authors: Miller Lauren E. , Bhattacharyya Neil 
Published: April 2021

Chronic rhinosinusitis (CRS) management frequently comprises conservative treatment, including a combination of topical and oral corticosteroids (OCSs). However, in the midst of the coronavirus disease 2019 (COVID‐19) pandemic, providers may have been reluctant to prescribe OCSs out of possible concern for an increased risk of contracting COVID‐19 or developing more severe COVID‐19 symptoms. This study thus sought to explore the association between the use of OCSs and the development of COVID‐19 in patients with CRS. We found no statistically significant difference in the rates of patients with a positive diagnosis of COVID‐19 who underwent an OCS treatment regimen compared to those who did not, both within 28 days (P =. 389) and 14 days (P =. 676) prior to the COVID‐19 test. Given OCSs are often a major component of medical management of CRS, this study proves helpful in counseling patients on risks of steroid use in CRS treatment during the COVID‐19 pandemic.

Published: April 2021

Background The risk of transmission of Coronavirus Disease 2019 (COVID-19) is increasingly understood to be greatest early after symptom onset, however, factors associated with prolonged and increased risk of transmission remain unclear. In settings where COVID-19 prevalence is low, there may be a benefit of extending the period that patients are isolated to decrease the risk of transmission. This study explored the duration of viral shedding in such a location, in patients with mild-moderate COVID-19 disease in Ballarat, Australia. Methods Patients diagnosed with COVID-19 disease using a real-time reverse-transcriptase–polymerase-chain-reaction (RT-PCR) assay from oropharyngeal and bilateral deep nasopharyngeal sampling and managed through Ballarat Health Services between March 1 and May 1, 2020 were included. Patients were retested if they were afebrile for >72 hours, asymptomatic and >14 days since symptom onset. If positive on retesting, patients were tested every 3 to 7 days thereafter. Results Patients underwent testing a median of 4 days (range 1-12) after initial symptom onset. Duration of symptoms ranged from 1 to 36 days. Positive tests were recorded up to a median of day 21 (range 6-38). Cycle thresholds were inversely correlated with time since symptom onset ( P < .0001). Median time to the first negative test was 25 days (range 12-32). Two patients who had remained asymptomatic for >7 days after initial symptom onset had recrudescence of mild symptoms on day 13 and 14; both tested positive on follow-up tests at this time. Conclusions This study demonstrates prolonged shedding of COVID-19 in patients with mild-moderate disease. It suggests that some patients with mild disease may have recrudescence of symptoms a week or more after their initial symptoms resolved.
Solidarity in a Community of Nursing Colleagues
Authors: Kristoffersen Margareth 
Published: April 2021

Introduction Several concepts have been used to describe the qualities of communities of nursing colleagues. Nonetheless, few studies have shed light on nursing communities by drawing on the concept of solidarity. Objective To explore solidarity among a community of nursing colleagues. Methods A qualitative research design with a reflective life world approach was selected. This study reused data from a larger Norwegian empirical study. The data from the original study consisted of qualitative interviews and follow-up interviews with 13 nurses (RNs). The research context was municipality and specialist health services. A secondary data analysis was conducted. The study was based on the SRQR reporting guidelines. Results The results were formulated under two themes: 1) having indispensable relationships and 2) encountering a relative absence of sympathy. Conclusion A sense of community among nursing colleagues seems to rely on solidarity: whatever affects one nurse affects another. The solidarity that arose from the content of commonalities involved maintaining indispensable relationships with nursing colleagues by supporting and aiding them and simultaneously enduring a relative absence of sympathy. Solidarity among the community in this study was not a peripheral concept of the general notion of solidarity, implying that the commonalities within the collegial relationships were ambiguous and could shift from something good to something relatively good and vice versa. Such a shift was evidenced by nurses’ experiences of their community.
Evaluation of erectile dysfunction in the ageing men using colour Doppler sonography
Authors: Aiyekomogbon J. O. , Itanyi D. U. , Atim T. , Igashi J. B. 
Published: April 2021

Abstract
Background
Erectile dysfunction (ED) is common among ageing men because of associated underlying risk factors which are peculiar to this category of patients. Endothelial dysfunction and replacement of cavernosal smooth muscles by collagen fibres are common in older men, making them prone to ED. It is either vasogenic, neurogenic, hormonal, cavernosal or psychogenic in origin, but vasogenic causes are the commonest. This study was aimed at establishing vasogenic causes among patients being evaluated for ED using Doppler ultrasound as this category of ED is amenable to either medical and/or surgical treatment.

Methods
The study was conducted from July 2015 to January, 2017 at Federal Medical Centre Abuja. Nineteen consecutive patients with clinical diagnosis of erectile dysfunction were evaluated with Doppler ultrasound scan using a high-frequency linear array transducer. The penile scan was done before and after intracavernosal injection of 20 µg of Prostaglandin E1 (PGE1). B-mode scan of the penis was done prior to intracavernosal injection of PGE1, and the spectral waveforms as well as peak systolic velocity (PSV) of the CA were recorded at 5 min interval, from 5 to 50 min post-intracavernosal injection of PGE1, using angle of insoation ≤ 60°.

Results
The age range of the patients was fifty to sixty-six years (mean: 57.4 ± 4.3 years), while the PSV of CA varied between 21.4 and 104.4 cm/s (mean: 46.2 ± 19.2) among the entire patients, between 21.4 and 22.3 cm/s (mean: 21.9 ± 0.7) among patients with arteriogenic ED, and between 25.0 and 74.9 cm/s (mean: 45.0 ± 15.5) among those with venogenic ED. Arteriogenic ED was found in two patients (10.6%), while venogenic ED was observed in seven patients, which constituted 36.8% of the entire research participants. None had Peyronie’s disease, penile fracture, penile tumour or mixed arteriogenic and venogenic ED.

Conclusion
47.4% of the patients had vasogenic ED and venogenic ED was more common than arterioegenic ED in the age range considered. This categorization of ED with Doppler study is imperative before initiating therapy as treatment protocol for vasogenic ED is aetiologic specific.
Imprints of independent allopolyploid formations on patterns of gene expression in two sibling yarrow species (Achillea, Asteraceae)
Authors: Chen Duo , Yan Peng-Cheng , Guo Yan-Ping 
Published: April 2021

AbstractBackgroundPolyploid species often originate recurrently. While this is well known, there is little information on the extent to which distinct allotetraploid species formed from the same parent species differ in gene expression. The tetraploid yarrow speciesAchillea alpinaandA. wilsonianaarose independently from allopolyploidization between diploidA. acuminataandA. asiatica. The genetics and geography of these origins are clear from previous studies, providing a solid basis for comparing gene expression patterns of sibling allopolyploid species that arose independently.ResultsWe conducted comparative RNA-sequencing analyses on the twoAchilleatetraploid species and their diploid progenitors to evaluate: 1) species-specific gene expression and coexpression across the four species; 2) patterns of inheritance of parental gene expression; 3) parental contributions to gene expression in the allotetraploid species, and homeolog expression bias. DiploidA. asiaticashowed a higher contribution than diploidA. acuminatato the transcriptomes of both tetraploids and also greater homeolog bias in these transcriptomes, possibly reflecting a maternal effect. Comparing expressed genes in the two allotetraploids, we found expression of ca. 30% genes were species-specific in each, which were most enriched for GO terms pertaining to “defense response”. Despite species-specific and differentially expressed genes between the two allotetraploids, they display similar transcriptome changes in comparison to their diploid progenitors.ConclusionTwo independently originatedAchilleaallotetraploid species exhibited difference in gene expression, some of which must be related to differential adaptation during their post-speciation evolution. On the other hand, they showed similar expression profiles when compared to their progenitors. This similarity might be expected when pairs of merged diploid genomes in tetraploids are similar, as is the case in these two particular allotetraploids.

Abstract
Background
The incidence of concurrent cancer and ischaemic heart disease (IHD) is increasing; however, the long-term patient prognoses remain unclear.

Methods
Five-year all-cause mortality data pertaining to patients in the Osaka Cancer Registry, who were diagnosed with colorectal, lung, prostate, and gastric cancers between 2010 and 2015, were retrieved and analysed together with linked patient administrative data. Patient characteristics (cancer type, stage, and treatment; coronary risk factors; medications; and time from cancer diagnosis to index admission for percutaneous coronary intervention [PCI] or IHD diagnosis) were adjusted for propensity score matching. Three groups were identified: patients who underwent PCI within 3 years of cancer diagnosis (n = 564, PCI + group), patients diagnosed with IHD within 3 years of cancer diagnosis who did not undergo PCI (n = 3058, PCI-/IHD + group), and patients without IHD (n = 27,392, PCI-/IHD- group). Kaplan–Meier analysis was used for comparisons.

Results
After propensity score matching, the PCI + group had better prognosis (n = 489 in both groups, hazard ratio 0.64, 95% confidence interval 0.51–0.81, P < 0.001) than the PCI-/IHD + group. PCI + patients (n = 282) had significantly higher mortality than those without IHD (n = 280 in each group, hazard ratio 2.88, 95% confidence interval 1.90–4.38, P < 0.001).

Conclusions
PCI might improve the long-term prognosis in cancer patients with IHD. However, these patients could have significantly worse long-term prognosis than cancer patients without IHD. Since the present study has some limitations, further research will be needed on this important topic in cardio-oncology.
