AbstractWe investigated the prevalence of coronaviruses in 44 bats from four families in northeastern Eswatini using high-throughput sequencing of fecal samples. We found evidence of coronaviruses in 18% of the bats. We recovered full or near-full-length genomes from two bat species: Chaerephon pumilus and Afronycteris nana, as well as additional coronavirus genome fragments from C. pumilus, Epomophorus wahlbergi, Mops condylurus, and Scotophilus dinganii. All bats from which we detected coronaviruses were captured leaving buildings or near human settlements, demonstrating the importance of continued surveillance of coronaviruses in bats to better understand the prevalence, diversity, and potential risks for spillover.
Applying Ramseyfication to Infrared Spectroscopy
Authors: Toppel Michael 
Published: December 2021

AbstractThe so-called Ramsey–Carnap approach, or Ramseyfication, has gone out of fashion in the philosophy of science. Advocates have tried to argue for a revival by writing methodological and metatheoretical studies of Ramseyfication. For this paper I have chosen a different approach; I will apply Ramseyfication to infrared spectroscopy—a method used in analytical chemistry—in order to logically analyse the relation between measurements and mathematical structures. My aim in doing so is to contribute to the debate about the Application Problem of Mathematics, thereby making a case for Ramseyfication as a method of study for scientific theories.
Wondering about the future
Authors: Torre Stephan 
Published: December 2021

AbstractWill it rain tomorrow? Will there be a sea battle tomorrow? Will my death be painful? Wondering about the future plays a central role in our cognitive lives. It is integral to our inquiries, our planning, our hopes, and our fears. The aim of this paper is to consider various accounts of future contingents and the implications that they have for wondering about the future. I argue that reflecting on the nature of wondering about the future supports an Ockhamist account of future contingents according to which many of them are true. Alternative accounts which maintain that no future contingents are true, either by claiming that they are all false or by claiming that they are neither true nor false, face difficulties concerning why it is appropriate to wonder about them. Reflecting on wondering in general, and wondering about the future in particular, suggests that in wondering how the future will go, we implicitly assume that there is a determinate fact of the matter. After presenting an attractive account of interrogative attitudes that has been recently proposed by Jane Friedman and outlining some norms governing wondering, I argue that all accounts of future contingents except Ockhamism face difficulties concerning why it is appropriate to wonder about them.
Quantum absentminded driver problem revisited
Authors: Fra̧ckiewicz Piotr , Rycerz Katarzyna , Szopa Marek 
Published: December 2021

AbstractThe aim of the paper is to study the problem of absentminded driver in the quantum domain. In the classical case, it is a well-known example of a decision problem with imperfect recall that exhibits lack of equivalence between mixed and behavioral strategies. The optimal payoff outcome is significantly lower than the maximum payoff appearing in the game. This raises the question whether a quantum approach to the problem can increase the strategic position of the decision maker. The results that we present in the paper clearly reveal the benefits from playing the absentminded problem with the aid of quantum objects. Through appropriately chosen initial quantum state, the unitary strategies enable the decision maker to obtain the maximum possible payoff. At the same time, our scheme comes down to the classical problem with a suitable restriction of unitary strategies.

AbstractComputational fluid dynamics (CFD) simulations are a vital part of the design process in the aerospace industry. Although reliable CFD results can be obtained with turbulence models, direct numerical simulation of complex bodies in three spatial dimensions (3D) is impracticable due to the massive amount of computational elements. For instance, a 3D direct numerical simulation of a turbulent boundary-layer over the wing of a commercial jetliner that resolves all relevant length scales using a serial CFD solver on a modern digital computer would take approximately 750 million years or roughly 20% of the earth’s age. Over the past 25 years, quantum computers have become the object of great interest worldwide as powerful quantum algorithms have been constructed for several important, computationally challenging problems that provide enormous speed-up over the best-known classical algorithms. In this paper, we adapt a recently introduced quantum algorithm for partial differential equations to Burgers’ equation and develop a quantum CFD solver that determines its solutions. We used our quantum CFD solver to verify the quantum Burgers’ equation algorithm to find the flow solution when a shockwave is and is not present. The quantum simulation results were compared to: (i) an exact analytical solution for a flow without a shockwave; and (ii) the results of a classical CFD solver for flows with and without a shockwave. Excellent agreement was found in both cases, and the error of the quantum CFD solver was comparable to that of the classical CFD solver.
OCLC library holdings: assessing availability of academic books in libraries in print and electronic compared to citations and altmetrics
Authors: Maleki Ashraf 
Published: December 2021

AbstractAlthough library holding data is constructed upon work format of books, it is less known how much print and electronic books in libraries contribute to the library holding counts. In response, this research is an attempt to explore the distribution of library holding data across work formats and investigate the availability of library print holdings and library electronic holdings for books as constituents of the library holding metric across fields and over time and compared with other book metrics. ISBNs, titles and author names of 119,794 Scopus-indexed book titles across 26 fields were examined for fourteen variables including OCLC Library Holdings, Scopus Citations, Google Books Citations, Goodreads engagements, and Altmetric indicators. There are three major findings: (a) library holdings are a more comprehensively available metric for books (over 97%) than any other metric and could be useful after short time after first edition publication, followed by Google Books, Goodreads and Scopus, respectively; (b) on average electronic holdings are seven times (median three times) more numerous than print holdings and their ratio is growing considerably for more recent books; (c) there is consistent downward trend in average print book holdings, suggesting that library print holding data are cumulative in nature and statistically comparable to formal citations; however, acquisition of electronic books in libraries is inconsistent in distribution plot as well as over time. In sum, the differences between print and electronic holding data are broad making them distinct metrics, suggesting that further research is needed for understanding their implications for book impact assessment.

Published: December 2021

Abstract
Purpose
In patients with a high pre-test probability of suffering from obstructive sleep apnea (OSA), (cardio)-respiratory polygraphy (RP; level 3) is commonly used for home sleep testing (HST); however, testing based on peripheral arterial tonometry (PAT) is increasingly recognized as an alternative method. The aim of the study was to compare sleep position, patients’ comfort, and technical failure rates of HST with RP and PAT in patients with suspected OSA.

Methods
Sleep position, patients’ comfort, and technical failure rates of RP and PAT were compared in 56 patients receiving two nights of HST with either RP or PAT in a randomized fashion.

Results
Time in supine position with PAT was significantly lower (173.7±88 min) compared to RP (181.7±103.7 min; p < 0.001), although the absolute mean difference was not clinically significant. Patients reported to sleep better, feeling less disturbed when falling asleep, losing less sensors, and fewer nightly awakenings with PAT, but experienced more pain at the side of the finger probe. Forty-five out of 56 patients (80%) rated PAT as being the superior sleep test and 49 out of 56 (88%) would prefer PAT for further investigations (p<0.001). PAT testing was associated with less technical failures.

Conclusion
The results demonstrate that HST with PAT leads to less time in supine sleep positioning, which may be clinically relevant in selected patients. Moreover, PAT is associated with less technical failures and is perceived with less discomfort during testing and a reduced number of nocturnal awakenings in patient self-reports.
Vulgar Talk and Learned Reasoning in Berkeley’s Moral and Religious Thought
Authors: Airaksinen Timo 
Published: December 2021

AbstractBerkeley “argues with the learned and speaks with the vulgar.” I use his double maxim to interpret his ethics. My approach is new. The Sermons and Guardian Essays mainly speak to the vulgar and Passive Obedience and Alciphron reason with the learned. The reward of ethics is eternal bliss in a future state: religion and ethics are connected. I study a set of problems: resurrection, eternal life, happiness, benevolence, the goodness of God, and self-love. Divine bliss is unlike any earthly happiness. The idea of law does not support benevolence, even if it is a Christian duty and virtue. God is good, but how to prove it? The learned must study the complex theodicy problem; the vulgar need assurance based on their sensuous experience and fervent hope of eternal bliss. Self-love may be a vital issue to the learned, although the vulgar may not realize their need to overcome it. The main questions concern Berkeley’s two approaches to ethical problems: first, how do their topics differ, and second, are they mutually consistent?
Disparities in ACL Reconstruction: the Influence of Gender and Race on Incidence, Treatment, and Outcomes

Abstract
Purpose of Review
Anterior cruciate ligament (ACL) rupture is a common injury that has important clinical and economic implications. We aimed to review the literature to identify gender, racial and ethnic disparities in incidence, treatment, and outcomes of ACL injury.

Recent Findings
Females are at increased risk for ACL injury compared to males. Intrinsic differences such as increased quadriceps angle and increased posterior tibial slope may be contributing factors. Despite lower rates of injury, males undergo ACL reconstruction (ACLR) more frequently. There is conflicting evidence regarding gender differences in graft failure and ACL revision rates, but males demonstrate higher return to sport (RTS) rates. Females report worse functional outcome scores and have worse biomechanical metrics following ACLR. Direct evidence of racial and ethnic disparities is limited, but present. White athletes have greater risk of ACL injury compared to Black athletes. Non-White and Spanish-speaking patients are less likely to undergo ACLR after ACL tear. Black and Hispanic youth have greater surgical delay to ACLR, increased risk for loss to clinical follow-up, and less physical therapy sessions, thereby leading to greater deficits in knee extensor strength during rehabilitation. Hispanic and Black patients also have greater risk for hospital admission after ACLR, though this disparity is improving.

Summary
Females have higher rates of ACL injury with inconclusive evidence on anatomic predisposition and ACL failure rate differences between genders. Recent literature has suggested inferior RTS and functional outcomes following ACLR in females. Though there is limited and mixed data on incidence and outcome differences between races and ethnic groups, recent studies suggest there may be disparities in those who undergo ACLR and time to treatment.
Using a cubic B-spline method in conjunction with a one-step optimized hybrid block approach to solve nonlinear partial differential equations
Authors: Ramos Higinio , Kaur Anurag , Kanwar V. 
Published: December 2021

AbstractIn this paper, we develop an optimized hybrid block method which is combined with a modified cubic B-spline method, for solving non-linear partial differential equations. In particular, it will be applied for solving three well-known problems, namely, the Burgers equation, Buckmaster equation and FitzHugh–Nagumo equation. Most of the developed methods in the literature for non-linear partial differential equations have not focused on optimizing the time step-size and a very small value must be considered to get accurate approximations. The motivation behind the development of this work is to overcome this trade-off up to much extent using a larger time step-size without compromising accuracy. The optimized hybrid block method considered is proved to be A-stable and convergent. Furthermore, the obtained numerical approximations have been compared with exact and numerical solutions available in the literature and found to be adequate. In particular, without using quasilinearization or filtering techniques, the results for small viscosity coefficient for Burgers equation are found to be accurate. We have found that the combination of the two considered methods is computationally efficient for solving non-linear PDEs.
“Incurable Megalomania” and “Fantasies of Expansion”: The German Army Reimagines Empire in Occupied Poland, 1915–1918
Authors: Kettler Mark T. 
Published: December 2021

AbstractPlans for a Polish “border strip” are frequently cited to argue that the German army entered the First World War committed to pacifying conquered space through Germanization. This article contends that, in 1914, the German officer corps did not understand national homogeneity as essential for imperial security. Many influential officers insisted that Polish identity was compatible with German imperial loyalty. They supported a multinational imperial model, proposing to trade Poland its cultural and political autonomy for the acceptance of German suzerainty in foreign policy and military command. The army's preference for Germanizing space developed during the occupation of Russian Poland, as officers learned to conflate diversity with imperial fragility. Only a series of political crises after 1916 shifted military opinion against multinational imperialism. Increasingly convinced that Poland would betray the German Empire, some officers abandoned multinationalism. Others revised their plans to contain Poland and fortify Germany by annexing and Germanizing Polish space.

AbstractDistinct bacterial trophic networks exist in the gut microbiota of individuals in industrialized and non-industrialized countries. In particular, non-industrialized gut microbiomes tend to be enriched withPrevotellaspecies. To study the development of thesePrevotella-rich compositions, we investigated the gut microbiota of children aged between 7 and 37 months living in rural Gambia (616 children, 1,389 stool samples, stratified by 3-month age groups). These infants, who typically eat a high-fibre, low-protein diet, were part of a double-blind, randomized iron intervention trial (NCT02941081) and here we report the secondary outcome. We found that child age was the largest discriminating factor between samples and that anthropometric indices (collection time points, season, geographic collection site, and iron supplementation) did not significantly influence the gut microbiome.Prevotella copri,Faecalibacterium prausnitziiandPrevotella stercoreawere, on average, the most abundant species in these 1,389 samples (35%, 11% and 7%, respectively). Distinct bacterial trophic network clusters were identified, centred around eitherP.stercoreaorF.prausnitziiand were found to develop steadily with age, whereasP.copri, independently of other species, rapidly became dominant after weaning. This dataset, set within a critical gut microbial developmental time frame, provides insights into the development ofPrevotella-rich gut microbiomes, which are typically understudied and are underrepresented in western populations.

AbstractWe aimed to search for common features in the autoreactive T cell receptor (TCR) repertoire in patients with rheumatoid arthritis (RA), focusing on the newly identified candidate antigen citrullinated Tenascin C (cit-TNC). Mononuclear cells from peripheral blood or synovial fluid of eight RA-patients positive for the RA-associated HLA-DRB1*04:01 allele were in-vitro cultured with recently identified citrullinated peptides from Tenascin C. Antigen-specific T cells were isolated using peptide-HLA tetramer staining and subsequently single-cell sequenced for paired alpha/beta TCR analyses by bioinformatic tools. TCRs were re-expressed for further studies of antigen-specificity and T cell responses. Autoreactive T cell lines could be grown out from both peripheral blood and synovial fluid. We demonstrate the feasibility of retrieving true autoreactive TCR sequences by validating antigen-specificity in T cell lines with re-expressed TCRs. One of the Tenascin C peptides, cit-TNC22, gave the most robust T cell responses including biased TCR gene usage patterns. The shared TCR-beta chain signature among the cit-TNC22-specific TCRs was evident in blood and synovial fluid of different patients. The identification of common elements in the autoreactive TCR repertoire gives promise to the possibility of both immune monitoring of the autoimmune components in RA and of future antigen- or TCR-targeted specific intervention in subsets of patients.
X-ray spectral-timing variability of 1A 0535+262 during the 2020 giant outburst

Published: December 2021

Context.The Be/X-ray binary 1A 0535+262 underwent a giant X-ray outburst in November 2020, peaking at ∼1 × 1038erg s−1(1–100 keV, 1.8 kpc), the brightest outburst recorded for this source so far. The source was monitored over two orders of magnitude in luminosity with Insight-HXMT, which allowed us to probe the X-ray variability in an unprecedented range of accretion rates.Aims.Our goal is to search for patterns of correlated spectral and timing behavior that can be used to characterize the accretion states in hard X-ray transient pulsars.Methods.We have studied the evolution of the spectral continuum emission using hardness-intensity diagrams and the aperiodic variability of the source by analyzing power density spectra. We have used phenomenological models to fit the various broadband noise components.Results.The hardness-intensity diagram displays three distinct branches that can be identified with different accretion regimes. The characteristic frequency of the noise components correlates with the luminosity. Our observations cover the highest end of this correlation, at luminosities not previously sampled. We have found evidence for a flattening of the correlation at those high luminosities, which might indicate that the accretion disk reached the closest distance from the neutron star surface during the peak of the outburst. We also find evidence for hysteresis in the spectral and timing parameters: at the same luminosity level, the spectrum is harder and the characteristic noise frequency larger during the rise than during the decay of the outburst.Conclusions.As in black-hole binaries and low-mass X-ray binaries, the hardness-intensity diagram represents a useful diagnostic tool for defining the source state in an accreting pulsar. Our timing analysis confirms previous findings from spectral analyses of a hysteresis pattern of variability, where the spectral and timing parameters adopt different values at similar luminosity depending on whether the source is in the rising or decaying phase of the outburst.

Abstract
Background There is a recent rise in the incidence of esophageal carcinoma in India. Surgical resection with or without neoadjuvant chemoradiation is the current treatment modality of choice. Postoperative complications, especially pulmonary complications, affect many patients who undergo open esophagectomy for esophageal cancer. Minimally invasive esophagectomy (MIE) could reduce the pulmonary complications and reduce the postoperative stay.
Methodology We performed a retrospective analysis of prospectively collected data of 114 patients with esophageal cancer in the department of surgical oncology at a tertiary cancer center in South India between January 2019 and March 2020. We included patients with resectable cancer of middle or lower third of the esophagus, and gastroesophageal junction tumors (Siewert I). MIE was performed in 27 patients and 78 patients underwent open esophagectomy (OE). The primary outcome measured was postoperative complications of Clavien–Dindo grade II or higher within 30 days. Other outcomes measured include overall mortality within 30 days, intraoperative complications, operative duration and the length of hospital stay.
Results A postoperative complication rate of 18.5% was noted in the MIE group, compared with 41% in the OE group (p = 0.034). Pulmonary complications were noted in 7.4% in the MIE group compared to 25.6% in the OE group (p = 0.044). Postoperative mortality rates, intraoperative complications, and other nonpulmonary postoperative complications were almost similar with MIE as with open esophagectomy. Although the median operative time was more in the MIE group (260 minutes vs. 180 minutes; p < 0.0001), the median length of hospital stay was shorter in patients undergoing MIE (9 days vs. 12 days; p = 0.0001).
Conclusions We found that MIE resulted in lower incidence of postoperative complications, especially pulmonary complications. Although, MIE was associated with prolonged operative duration, it resulted in shorter hospital stay.
