ABSTRACT

Background
The difference in outcomes of cancer surgery between patients with and without kidney failure with dialysis therapy (KFDT) remains uncertain.

Methods
Using 2010–18 data in a national inpatient database in Japan, we identified patients who had undergone resection of colorectal, lung, gastric or breast cancer. We matched selected patient characteristics, type of cancer, surgical procedure and hospital of up to four patients without KFDT to each patient with KFDT. We assessed 30-day mortality and postoperative complications.

Results
Through matching, we identified 2248 patients with KFDT (807 with colorectal, 579 with lung, 500 with gastric and 362 with breast cancer) and 8210 patients without KFDT (2851 with colorectal, 2216 with lung, 1756 with gastric and 1387 with breast cancer). Postoperative complications occurred in a higher proportion of patients with KFDT than of those without KFDT after colorectal {20.3% versus 14.6%; risk difference (RD): 5.7% [95% confidence interval (95% CI) 2.6%–8.8%]}, lung [18.0% versus 12.9%; RD: 5.1% (95% CI 1.6%–8.4%)], gastric [25.0% versus 13.2%; RD: 11.8% (95% CI 7.6%–16.2%)] and breast cancer surgery [7.5% versus 3.5%; RD: 3.9% (95% CI 1.1%–6.9%)]. Patients with KFDT had a higher 30-day mortality than those without KFDT after gastric cancer surgery [1.6% versus 0.3%; RD: 1.3% (95% CI 0.1%–2.3%)]. Heart failure and ischemic heart disease occurred more frequently in patients with KFDT.

Conclusions
Patients with KFDT had higher rates of postoperative complications and 30-day mortality; however, RDs varied between cancer types. The higher rates of postoperative complications in patients with KFDT were mainly attributable to cardiovascular complications.

Abstract

Aims
The European Association of Cardiovascular Imaging Scientific Initiatives Committee conducted a global survey to evaluate the impact of the 2019 coronavirus disease (COVID-19) pandemic on the mental well-being of cardiac imaging specialists.

Methods and results
In a prospective international survey performed between 23 July 2021 and 31 August 2021, we assessed the mental well-being of cardiac imaging specialists ∼18 months into the COVID-19 pandemic. One-hundred-and-twenty-five cardiac imaging specialists from 34 countries responded to the survey. More than half described feeling anxious during the pandemic, 34% felt melancholic, 27% felt fearful, and 23% respondents felt lonely. A quarter of respondents had increased their alcohol intake and more than half reported difficulties in sleeping. Two-thirds of respondents described worsening features of burnout during the past 18 months, 44% considered quitting their job. One in twenty respondents had experienced suicidal ideation during the pandemic. Despite these important issues, the majority of participants (57%) reported having no access to any formal mental health support at work.

Conclusion
The survey has highlighted important issues regarding the mental well-being of cardiac imaging specialists during the COVID-19 pandemic. This is a major issue in our sub-specialty, which requires urgent action and prioritization so that we can improve the mental health of cardiovascular imaging specialists.
King Ine (688–726) and the Writing of English Law in Latin
Authors: Ivarsen Ingrid 
Published: January 2022

Abstract
It is commonly supposed that all Anglo-Saxon laws were composed in Old English. This article argues that the law-code in the name of King Ine of Wessex (r. 688–726) was written in Latin in his reign and only assumed its surviving Old English form in the ninth century when it was translated from Latin and appended to King Alfred’s law-code. Linguistic evidence indicates that Ine’s language is that of a ninth-century translator, possibly working with Alfred’s law-code, while its legal content is that of seventh-century Wessex. There are also several close parallels to continental legislation in Ine’s laws, both in language and in content. This article suggests that these may be the result of Frankish legislation serving as a model for or inspiration to the makers of Ine’s laws. The translation theory presented here explains many of the notorious linguistic peculiarities and problems of this text and its role within Alfred’s code.

Abstract
This work compared response surface methodology (RSM) and genetic algorithm (GA) analysis to optimize the lactic acid content by Lactobacillus rhamnosus PTCC 1637 and Lactobacillus acidophilus PTCC 1643 in a medium based of date syrup. Three parameters including concentrations of sucrose (10 and 20% (w/w)) and yeast extract (1, 2 and 3% (w/w)) along with different amplitudes of ultrasound (30 kHz, 25 and 50%) were investigated in terms of their impacts on both viable cell counts and lactic acid production. Regarding to RSM and GA, optimized samples were selected by achieving high lactic acid concentration. The results indicated that an increase in the amounts of sucrose and yeast extract led to increasing the cell growth and lactic acid production. Application of ultrasound at 25% amplitude significantly (P&lt;0.05) stimulated the fermentation process. However, increasing the amplitude to 50% significantly (P&lt;0.05) decreased the lactic acid production as compared to the control samples. The best treatment was observed at 20% sucrose, 3% yeast extract and 25% ultrasound amplitude. The present results indicated that the best productivity of lactic acid can be achieved at appropriate fermentation conditions including suitable amplitude of ultrasound and supplementation of date syrup.
3-D stripping inversion based on measured terrestrial potential field and seismic data over Hodein Basin area, Southeastern Desert, Egypt
Authors: Elghrabawy Osama , Khalifa Khaled 
Published: January 2022

SUMMARY
This study aims to present a 3-D stripping inversion over the Hodein Basin area in the Southeastern Desert based on the Fourier approach and evaluate the method based on the availability of data constraints. Before submitting the data sets for inversion, the gravity and magnetic data were subjected to process corrections, which enhanced the geological signal, thereby improving the inversion outputs. The Kharit-1 well was drilled in the central part of the basin area by Repsol in 1998. The interpreted seismic profiles revealed cumulative stratigraphic sequences in the study area, including basement complex, Kom Ombo Equivalent and Six Hills formation. Based on these constraints, the 3-D model was constructed and produced good fit statistics with an error of approximately 1.4 per cent for the gravity data and 9.7 per cent for the magnetic data. The basement layer becomes deeper in the middle of the basin, reaching a value of −2687 m around Wadi Kharit and Wadi Timsah. The basement layer is exposed and shallow in the NE and SW flanks of the main basin. The top of Kom Ombo Equivalent formation matches well with the basement relief. It reaches at the middle of basin area −1968.5 m, the greatest thickness at Wadi Timsah, up to −1200 m, while it decreases to the northwest, where it reaches −185 m. The top of the Six Hills formation reveals a shallow depth of 430 m asl along the basin area, except for the middle part, which reaches −1200 m. Based on four seismic depth profiles, an uncertainty investigation of the inversion results was performed, showing an error of approximately 10 per cent. In conclusion, the resultant basement and two stripping sedimentary layers reveal that the study area is characterized by a broad basin directed in the NW direction and dissected by normal faults, forming small subbasins.
Exploring fishers’ perceptions of index insurance and coral reef health in the context of climate-driven changes in extreme events

Abstract
Climate-change-driven storminess and extreme events are increasingly challenging fishers in tropical island countries. Weather-based index insurance is an emerging tool that can assist fishing communities in their recovery and adaptation to such events. In these regions, coral reefs support valuable fisheries and also provide coastal protection during extreme events. Surveying 80 fishers in Grenada, this exploratory study examined fishers’ perceptions of index insurance in the context of their experiences of extreme events. We also explore perceptions of reef health and its’ connections to fishing outcomes and coastal protection, given the indirect role this plays in supporting fishers’ resilience through associated fisheries and storm protection. Most fishers viewed extreme events as a severe risk to their livelihoods, affecting their ability to make future plans. Fishers comprehended the links between improved reef health and positive impacts on fishing (higher catches and incomes). Several challenges regarding index insurance were raised, which centred on themes of flexibility, affordability, inclusivity, and accessibility. These could pose barriers to fishers and undermine demand for or participation in such schemes. As such, research, design, and implementation of future index insurance schemes should consider issues raised by fishers to ensure that provision is equitable and improve uptake.
Topological Triviality in Families of Functions on Subanalytic Sets and Complex Analytic Spaces
Authors: Menegon Aurélio , de Jesus-Almeida Jonathas P 
Published: January 2022

AbstractWe study families of analytic functions defined on either subanalytic sets or complex analytic spaces. We give sufficient conditions for a family depending linearly on one parameter to have constant topological type, extending classical results due to Lê and Ramanujam [9] and Parusiński [12]. In the particular case of isolated singularity families defined on an ICIS, we prove that the $\mu $-constancy implies constant topological type.

Published: January 2022

Abstract
Brazil is the third largest contributor to Green Analytical Chemistry, and there is significant participation of toxicologists in the development and improvement of environmental techniques. Currently, toxicologists have their own strategies and guidelines to promote the reduction/replacement or elimination of solvents, reduce the impacts of derivatization and save time, among other objectives, due to the peculiarities of toxicological analysis. Thus, this review aims to propose the concept of Green Analytical Toxicology and conduct a discussion about its relevance and applications specifically in forensic toxicology, using the microextraction methods developed for the determination of cocaine and its metabolites as examples.
#GirlGamers, Soldiers, and Public Relations: Analyzing Gender Representation in U.S. Army Esports
Authors: Fisher Jolene , Foust Joshua 
Published: January 2022

AbstractWhile interest in esports is widespread across demographic categories, the gendered norms surrounding video game play have been replicated, resulting in a male-dominated space. Scholars argue that broadening representations of gamers is necessary to normalizing women’s presence in esports. As nongaming organizations enter the space, they have a unique opportunity to disrupt established norms through their representations of esports competitors. This study analyzes the representation of U.S. Army Esports (USAE) team members via official social media channels. USAE was created as a public relations tool to engage with a younger audience, redefine the public image of the Army, and recruit soldiers. Using a critical public relations framework and critical discourse analysis, we examine the discourse around gender and esports constructed through USAE’s representation of team members and the role of public relations practice in reinforcing or disrupting existing norms.
Semantic data management in P2P systems driven by self-esteem
Authors: Caroprese Luciano , Zumpano Ester 
Published: January 2022

Abstract
This paper is a contribution to semantic data management in P2P systems. It is based on the previous works of the same authors in which a declarative semantics for P2P systems is defined: under this semantics, only facts not making the local databases inconsistent are imported (Weak Models) and the Maximal Weak Models are those in which peers import maximal sets of facts not violating integrity constraints. The proposal, presented in this paper, stems from the following two observations: (i) the Maximal Weak Model Semantics ensures that locally consistent P2P systems always admit a maximal weak model, but fails for locally inconsistent P2P systems; (ii) the self-esteem degree of a peer should impact on the interaction with other peers in the system so that driving the integration process. From the above-mentioned observations a more general framework is presented. Our proposal is able to manage local inconsistencies and allows to model a peer integration process driven by the self-esteem degree of each peer. Different self-esteem degrees could be considered; in this paper we focus our attention on three different scenarios in which a generic peer can declare an high, low or medium self-esteem degree, stating respectively that it trusts its own knowledge more, less or equally with respect to the knowledge that can be provided from the rest of the system. Three different basic semantics are proposed, High, Low, Medium Self-Esteem Semantics and results about the computational complexity of P2P logic queries are investigated by considering brave and cautions reasoning. The paper also presents an extension of the basic framework of the Self-Esteem Semantics that models a finer-grained self-esteem concept and allows each peer to exhibit different levels of self-esteem each of them defined with respect to a subset of its mapping rules.
The nature of sub-millimetre galaxies II: an ALMA comparison of SMG dust heating mechanisms
Authors: Ansarinejad B , Shanks T , Bielby R M , Metcalfe N , Infante L , Murphy D N A , Rosario D J , Stach S M 
Published: January 2022

ABSTRACT
We compare the contribution of active galactic nuclei (AGNs) and star formation towards dust heating in sub-mm galaxies (SMGs). We have used ALMA at 0.1-arcsec resolution to image a complete flux-limited sample of seven sub-mm sources previously shown to have spectral energy distributions that were as well-fitted by obscured AGN as star-forming galaxy templates. Indeed, two sub-mm sources were known to be quasars from their absorbed X-ray emission. We find the sub-mm sizes of all SMGs to be small (≈1−2 kpc) and generally ∼3 times smaller than any host detected in the near-infrared (NIR). In all cases, the five SMGs are comparable in sub-mm size to the two known quasars and four z ≈ 6 quasars, also observed with ALMA. We detect no evidence of diffuse spiral arms in this complete sample. We then convert the far-infrared (FIR) luminosities to star formation rate (SFR) surface densities and find that the SMGs occupy the same range as the known quasars in our sample. We conclude that in terms of sub-mm size, extent relative to host and SFR density as well as luminosity and mid-IR (MIR) colour, there is little distinction between the SMGs and sub-mm bright quasars. Finally, we present preliminary evidence that SMGs with higher MIR luminosities and sub-mm loud quasars tend to have dust components that range to hotter temperatures than their less luminous SMG counterparts. In light of these results, we continue to suggest that luminous SMGs may host dust-absorbed quasars that may simultaneously dominate the FIR and hard X-ray backgrounds.
A study on the solar coronal dynamics during the post-maxima phase of the solar cycle 24 using S-band radio signals from the Indian Mars Orbiter Mission

Published: January 2022

ABSTRACT
Radio signals from India’s Mars Orbiter Mission (MOM) have been used to study turbulence in the solar plasma during the post-maximum phase of solar cycle 24. S-band (2.29 GHz) radio carrier downlink signals from MOM were received at the Indian Deep Space Network, Bangalore, and frequency residuals were spectrally analysed to obtain coronal turbulence spectra at heliocentric distances ranging between 4 and 20 R⊙, corresponding to coronal regions where the solar wind is primarily accelerated. The frequency fluctuation spectrum relates to the turbulence regime in the near-Sun region. The turbulence power spectrum (the temporal spectrum of frequency fluctuations) at smaller heliocentric distances (&lt;10 R⊙) reveals flattening in lower-frequency regions, with a spectral index αf ∼ 0.3−0.5, which corresponds to the solar wind acceleration region. For larger heliocentric distances (&gt;10 R⊙), the curve steepens with a spectral index αf ∼ 0.7−0.8, a value close to 2/3 and indicative of a developed Kolmogorov-type turbulence spectrum. The findings are consistent with earlier results. Plausible explanations to support the theory of coronal heating by magnetohydrodynamic waves and the acceleration of the solar wind are presented. An insight into the feeble maximum of solar cycle 24 is discussed.
The low-end of the black hole mass function at cosmic dawn

Published: January 2022

ABSTRACT
Understanding the formation and growth of supermassive black holes (SMBHs) at high redshift represents a major challenge for theoretical models. In this work, we investigate the early evolution of the first SMBHs by constraining their distribution in mass and luminosity at z &gt; 4. In particular, we focus on the poorly explored low-mass end of the nuclear black hole (BH) distribution down to z ≃ 4, and explore its connection with the nature of the first BH seeds and the processes governing their mass growth. To this aim, we have developed CAT (Cosmic Archaeology Tool), a new semi-analytic model that describes the formation of the first stars and BHs in a self-consistent way and follows the co-evolution of nuclear BHs and their host galaxies for a representative population at z &gt; 4. We find that current observational constraints favour models where the growth of BH seeds is Eddington limited and occurs at the Bondi–Hoyle–Lyttleton rate or where super-Eddington accretion occurs via a slim disc during gas-rich galaxy mergers. The main difference between these two model variants lies at the low end of the predicted mass and luminosity functions at 4 ≤ z ≤ 6, where a clear gap appears in the first model, reflecting the stunted growth of light BH seeds formed as remnants of the first stars. Detecting this signature will be extremely challenging even for the future generation of space observatories, such as JWST, Athena, and Lynx.
The pre-He white dwarfs in eclipsing binaries – III. WASP 1625−04

Published: January 2022

ABSTRACT
1SWASP J162545.15−043027.9 (WASP 1625−04) has been announced as one of EL CVn candidates showing total primary eclipses and ellipsoidal variations. This paper presents the absolute properties of the binary star, based on our high-resolution spectroscopy conducted from 2015 through 2020. From the spectral analysis, the radial velocities (RVs) for both components were obtained with the effective temperature Teff, 1 = 8990 ± 200 K and the rotational rate $v_1\sin \, i=53\pm 5$ km s−1 for the more massive primary. The RV measurements were analysed with archival WASP photometry. From the modelling we obtained: M1 = 1.745 ± 0.013 M⊙, M2 = 0.187 ± 0.002 M⊙, R1 = 1.626 ± 0.008 M⊙, R2 = 0.290 ± 0.003 M⊙, L1 = 15.5 ± 1.4 L⊙, and L2 = 1.84 ± 0.16 L⊙. In the Hertzsprung–Russell diagram, WASP 1625-04 A lies on the zero-age main sequence and its companion accords well with the helium-core white dwarf models of 0.19 M⊙ in the constant luminosity phase. Our improved results demonstrate that WASP 1625−04 is a typical EL CVn-type binary with a low-mass ratio and M2 combination in the thin-disc population and is the product of the stable, non-conservative mass transfer of the precursor binary.
Particle acceleration and multimessenger emission from starburst-driven galactic winds
Authors: Peretti Enrico , Morlino Giovanni , Blasi Pasquale , Cristofari Pierre 
Published: January 2022

ABSTRACT
The enhanced star-forming activity, typical of starburst galaxies, powers strong galactic winds expanding on kiloparsec (kpc) scales and characterized by bubble structures. Here we discuss the possibility that particle acceleration may take place at the termination shock of such winds. We calculate the spectrum of accelerated particles and their maximum energy, which turns out to range up to a few hundred petaelectronvolt (PeV) for typical values of the parameters. Cosmic rays accelerated at the termination shock are advected towards the edge of the bubble excavated by the wind and eventually escape into extragalactic space. We also calculate the flux of gamma-rays and neutrinos produced by hadronic interactions in the bubble, as well as the diffuse flux resulting from the superposition of the contribution of starburst galaxies on cosmological scales. Finally, we compute the diffuse flux of cosmic rays from starburst bubbles and compare it with existing data.
Robustness of particle creation in the formation of a compact object

Published: January 2022

Abstract
Hawking predicted that the formation of a black hole by gravitational collapse causes quantum particle creation and the spectrum of the particles is almost thermal. This phenomenon is called Hawking radiation. Recently, it has been predicted that particle creation may drastically change from Hawking radiation to a strong double burst if the gravitational collapse suddenly stops just before the formation of the event horizon. In contrast with Hawking radiation, the burst may be so strong that it can be of observational interest even for collapsing objects with astrophysical mass scales. However, the burst phenomenon has been predicted through studies of idealized models in which a spherical hollow shell begins to collapse, but stops shrinking and eventually settles down to a static “star”. Therefore, one might guess that it could be particular to the hollow shell model. In this paper, we study particle creation due to the gravitational collapse of a spherical object whose interior is filled with matter. In this model, we obtain similar results to those in the case of the hollow shell model. This implies that the double burst is a robust property of particle creation by the sudden braking of gravitational collapse.
