Published: April 2022

AbstractThe ant colony optimization algorithm is a classical swarm intelligence algorithm, but it cannot be used for continuous class optimization problems. A continuous ant colony optimization algorithm (ACOR) is proposed to overcome this difficulty. Still, some problems exist, such as quickly falling into local optimum, slow convergence speed, and low convergence accuracy. To solve these problems, this paper proposes a modified version of ACOR called ADNOLACO. There is an opposition-based learning mechanism introduced into ACOR to effectively improve the convergence speed of ACOR. All-dimension neighborhood mechanism is also introduced into ACOR to further enhance the ability of ACOR to avoid getting trapped in the local optimum. To strongly demonstrate these core advantages of ADNOLACO, with the 30 benchmark functions of IEEE CEC2017 as the basis, a detailed analysis of ADNOLACO and ACOR is not only qualitatively performed, but also a comparison experiment is conducted between ADNOLACO and its peers. The results fully proved that ADNOLACO has accelerated the convergence speed and improved the convergence accuracy. The ability to find a balance between local and globally optimal solutions is improved. Also, to show that ADNOLACO has some practical value in real applications, it deals with four engineering problems. The simulation results also illustrate that ADNOLACO can improve the accuracy of the computational results. Therefore, it can be demonstrated that the proposed ADNOLACO is a promising and excellent algorithm based on the results.
Gastral Drumming in Vespula germanica (Hymenoptera: Vespidae): Vibrational Communication at Night Suggests Additional Roles in Colony Organization
Authors: Taylor Benjamin J 
Published: April 2022

Abstract
Gastral drumming (GD) is a type of vibrational communication that has been reported in several species of yellowjackets and hornets. Despite early claims that it acts as a hunger signal, a more recent study found evidence that it acts as a nest-based food-recruitment signal, the first reported for eusocial wasps. Early studies also claimed, without supporting data, that it is produced most often in the early morning hours when the sun rises. Here, I recorded drumming continuously in colonies of Vespula germanica (Fabricius) to assess whether production was highest in the morning. Although I found no evidence in support of greater early morning production, I found, surprisingly, that it is produced at night, a time when foraging does not occur. When these results are combined with the results from previous studies on this species and similar findings in honey bees, they suggest that GD may be a modulatory signal, which acts by increasing general activity levels and by increasing the rate that individuals come into contact with social cues.

Abstract

Objective
The aim of this study was to investigate the efficacy and safety of tranexamic acid in patients undergoing surgery for bone and soft tissue tumors.

Methods
Data were retrospectively collected from 454 consecutive patients with bone and soft tissue tumors who underwent open biopsy, marginal resection, curettage or wide resection between January 2017 and December 2018. We performed propensity score matching of patients who received tranexamic acid with those who did not. The primary outcome variables were intra-operative, peri-operative and estimated blood loss (IBL, PBL and EBL, respectively).

Results
Tranexamic acid (+) and tranexamic acid (−) groups were defined according to whether patients received tranexamic acid or not. Among the 454 patients, open biopsy was performed in 102, marginal resection in 175, curettage in 54 and wide resection in 123. Intra-operative blood loss was significantly lower in the tranexamic acid (+) group than in the tranexamic acid (−) group for both marginal and wide resection (marginal resection: 17.3 vs. 70.3 g, respectively, P = 0.045; wide resection: 128.8 vs. 273.1 g, respectively, P = 0.023). Peri-operative blood loss and estimated blood loss were also significantly lower in the tranexamic acid (+) group for wide resection (peri-operative blood loss: 341.5 vs. 686.5 g, respectively, P = 0.0039; estimated blood loss: 320.7 vs. 550.6 ml, respectively, P = 0.030). No venous thromboembolism occurred in either group.

Conclusion
This study suggests that TXA administration safely and effectively reduces blood loss, in particular for wide resection, with no increase in the rate of adverse events.
New Distribution Records of Biting Midges of the Genus Culicoides (Diptera: Ceratopogonidae) Latreille, Culicoides bergi and Culicoides baueri, in Southern Ontario, Canada

Published: April 2022

Abstract
Some species of Culicoides Latreille (Diptera: Ceratopogonidae) can be pests as well as pathogen vectors, but data on their distribution in Ontario, Canada, are sparse. Collecting this baseline data is important given ongoing, accelerated alterations in global climate patterns that may favor the establishment of some species in northern latitudes. Culicoides spp. were surveyed using UV light traps over two seasons in 2017 and 2018 at livestock farms in southern Ontario, Canada. Two Culicoides spp. not previously recorded in Canada were identified, C. bergi and C. baueri, representing new country and provincial records. Unlike some congenerics, these two species are not currently recognized as vectors of pathogens that pose a health risk to humans, livestock or wildlife in North America. However, the possibility that these Culicoides species may have recently expanded their geographic range, potentially in association with climate and/or landscape changes, warrants ongoing attention and research. Furthermore, our results provoke the question of the potential undocumented diversity of Culicoides spp. in Ontario and other parts of Canada, and whether other Culicoides spp. may be undergoing range expansion. The current and future distributions of Culicoides spp., and other potential vectors of human, agricultural, and wildlife health significance, are important to identify for proper disease risk assessment, mitigation, and management.
To Misspecify Is Common, to Probe Misspecification Scientific: Common “Confounds” in Pornography Research May Actually Be Predictors
Authors: Wright Paul J , Tokunaga Robert S , Herbenick Debby , Paul Bryant 
Published: April 2022

AbstractThe ills of modeling variables substantively involved in a causal process as “controls” have been discussed extensively by social scientists who do not study media. Until recently, Slater was one of the few communication scientists to suggest that media effects scholars engage in overcontrol. Bushman and Anderson have now echoed this concern in the context of a broader treatise on research trends in the media violence literature. The present study responded to Wright’s recent discussion of control variable usage in the pornography literature. Specifically, using a national probability sample of approximately 1,900 U.S. adults, the present study assessed whether multiple demographic variables routinely modeled as controls in the pornography effects literature may be better conceptualized as initiating predictors. Results were inconsistent with the confounding approach but consistent with the hypothesis that individual differences predict cognitive response states that increase or decrease the likelihood of media effects.
The abundance effect on network nestedness is stronger for parasitic than herbivory interactions
Authors: Lan Bin , Hu Xiaoli , Wang Ying , Sun Shucun 
Published: April 2022

Abstract
It has been suggested that the importance of network architecture to species diversity and stability should be based on preference networks (comprised of niche differentiations), rather than observational networks, because species abundance may significantly affect interaction frequencies. Considering that resource abundance is usually greater for herbivores than parasites, we hypothesize that the abundance effect is stronger for parasitic than herbivory interactions. To test this hypothesis, we collected 80 quantitative observational networks including 34 herbivorous and 46 parasitic networks from the published literature, and derived preference networks by removing the effects of species abundance. We then determined the network nestedness using both weighted NODF and spectral radius. We also determined species degree distribution, interaction evenness, weighted connectance and robustness for both observational and preference networks. The observational networks (including both herbivory and parasitic networks) were more nested judged by weighted NODF than spectral radius. Preference networks were less nested for parasitic than herbivory networks in terms of both weighted NODF and spectral radius, possibly because removing the abundance effect increased interaction evenness. These trends indicate that the abundance effect on network nestedness is stronger for parasitic than herbivory networks. Weighted connectance and robustness were greater in most preference networks than observational networks, indicating that preference networks may have high network stability and community persistence compared with observational ones. The data indicate that future network analyses should not only address the structural difference between mutualistic and antagonistic interactions, but also between herbivory and parasitic interactions.
Making Desegregation Work: Citizen Participation and Bureaucratic Resistance in the Boston Public Schools, 1974–85
Authors: de Jong Greta 
Published: April 2022

Abstract
Court-ordered desegregation of the Boston Public Schools in the 1970s has often been cast as an example of federal overreach that inflicted a disruptive “forced busing” plan on the city, generating only racial conflict and trauma while failing to ensure educational equality. Yet by encouraging citizen participation in developing and implementing plans for eliminating racism from the school system, the court order opened space for parents and community members to get involved in the public schools on an unprecedented scale. While some white Bostonians responded to desegregation with racist violence, others took advantage of the opportunities provided by the court order to press their vision for a more inclusive school system that would prepare children to live in an interracial democracy. Their efforts came up against an entrenched, self-interested bureaucracy that had no interest in sharing power or significantly reallocating educational resources. The struggles over education reform that played out in the offices of school administrators reveal the diverse interests and motivations that undermined school desegregation in Boston and allowed inequities to persist.
Exploring cyanobacterial diversity for sustainable biotechnology
Authors: Selão Tiago Toscano 
Published: April 2022

Abstract
Cyanobacteria are an evolutionarily ancient and diverse group of microorganisms. Their genetic diversity has &#x2028;allowed them to occupy and play vital roles in a wide range of ecological niches, from desert soil crusts to tropical oceans. Owing to bioprospecting efforts and the development of new platform technologies enabling their study and manipulation, our knowledge of cyanobacterial metabolism is rapidly expanding. This review explores our current understanding of the genetic and metabolic features of cyanobacteria, from the more established cyanobacterial model strains to the newly isolated/described species, particularly the fast-growing, highly productive, and genetically amenable strains, as promising chassis for renewable biotechnology. It also discusses emerging technologies for their study and manipulation, enabling researchers to harness the astounding diversity of the cyanobacterial genomic and metabolic treasure trove towards the establishment of a sustainable bioeconomy.
Dynamics of Colombo’s Top: non-trivial oblique spin equilibria of super-Earths in multiplanetary systems
Authors: Su Yubo , Lai Dong 
Published: April 2022

ABSTRACT
Many Sun-like stars are observed to host close-in super-Earths (SEs) as part of a multiplanetary system. In such a system, the spin of the SE evolves due to spin–orbit resonances and tidal dissipation. In the absence of tides, the planet’s obliquity can evolve chaotically to large values. However, for close-in SEs, tidal dissipation is significant and suppresses the chaos, instead driving the spin into various steady states. We find that the attracting steady states of the SE’s spin are more numerous than previously thought, due to the discovery of a new class of ‘mixed-mode’ high-obliquity equilibria. These new equilibria arise due to subharmonic responses of the parametrically driven planetary spin, an unusual phenomenon that arises in non-linear systems. Many SEs should therefore have significant obliquities, with potentially large impacts on the physical conditions of their surfaces and atmospheres.
Infrared and optical detectability of Dyson spheres at white dwarf stars
Authors: Zuckerman B 
Published: April 2022

ABSTRACT
It has been hypothesized that advanced technological civilizations will construct giant space colonies and supporting infrastructures to orbit about their home stars. With data from recent satellites that operate at infrared and optical wavelengths (Spitzer, Wide-field Infrared Survey Explorer, Transiting Exoplanet Survey Satellite, Kepler), in company with a few modest assumptions, it is now possible to begin to constrain observationally the frequency of such space-based civilizations in our Milky Way Galaxy.
A mid-infrared study of superluminous supernovae
Authors: Sun Luming , Xiao Lin , Li Ge 
Published: April 2022

ABSTRACT
We present the mid-infrared (MIR) light curves (LC) of 10 superluminous supernovae (SLSNe) at z &lt; 0.12 based on WISE data at 3.4 and 4.6 $\mu$m. Three of them, including PS15br, SN 2017ens, and SN 2017err show rebrightening which started at 200–400 d and ended at 600–1000 d, indicating the presence of dust. In four of the left seven SLSNe, dust emission was detected with monochromatic luminosities of $10^7\sim 10^8\, {\rm L}_\odot$ at epochs of 100–500 d based on MIR colours W1 − W2 ∼ 1. Among the three SLSNe which show rebrightening, we further analysed PS15br and SN 2017ens. We modelled the SEDs at 500–700 d, which gives dust temperatures of 600–1100 K, dust masses of $\gtrsim 10^{-2}\, {\rm M}_\odot$, and luminosities of $10^8\sim 10^9\, {\rm L}_\odot$. Considering the time delay and the huge amount of energy released, the emitting dust can hardly be pre-existing dust heated whether collisionally by shocks or radiatively by peak SLSN luminosity or shock emission. Instead, it can be newly formed dust additionally heated by the interaction of circumstellar medium, indicated by features in their spectra and slowly declining bolometric LCs. The dust masses appear to be ten times greater than those formed in normal core-collapse supernovae at similar epochs. Combining with the analysis of SN 2018bsz by Chen et al. (2021), we suggest that SLSNe have higher dust formation efficiency, although future observations are required to reach a final conclusion.
Stellar populations of a sample of far-infrared AGN and non-AGN green valley galaxies
Authors: Mahoro Antoine , Pović Mirjana , Väisänen Petri , Nkundabakura Pheneas , van der Heyden Kurt 
Published: April 2022

ABSTRACT
We present a study on the stellar populations and stellar ages of a subsample of far-infrared (FIR) active galactic nucleus (AGN) and non-AGN green valley galaxies at ${0.6\, \lt \, z\, \lt \, 1.0}$ using the data from the Cosmological Evolution Survey field. We used long-slit spectroscopy and derived stellar populations and stellar ages using the stellar population synthesis code ‘starlight’ and analysed the available Lick/IDS indices, such as Dn4000 and HδA. We find that both FIR AGN and non-AGN green valley galaxies are dominated by intermediate stellar populations (67 per cent and 53 per cent, respectively). The median stellar ages for AGNs and non-AGNs are ${\log t\, =\, 8.5}$ and ${\, 8.4\, \rm yr}$, respectively. We found that majority of our sources (62 per cent of AGNs and 66 per cent of non-AGNs) could have experienced bursts and continuous star formation (SF). In addition, most of our FIR AGNs (38 per cent) compared to FIR non-AGNs (27 per cent) might have experienced a burst of SF more than 0.1 Gyr ago. We also found that our FIR AGN and non-AGN green valley galaxies have similar quenching time-scales of ∼ 70 Myr. Therefore, the results obtained here are in line with our previous results where we do not find that our sample of FIR AGNs in the green valley shows signs of negative AGN feedback, as has been suggested previously in optical studies.
XMM–Newton observations of the narrow-line Seyfert 1 galaxy IRAS 13224−3809: X-ray spectral analysis II

ABSTRACT
Previously, we modelled the X-ray spectra of the narrow-line Seyfert 1 galaxy IRAS 13224−3809 using a disc reflection model with a fixed electron density of 1015 cm−3. An additional blackbody component was required to fit the soft X-ray excess below 2 keV. In this work, we analyse simultaneously five flux-resolved XMM–Newton spectra of this source comprising data collected over 2 Ms. A disc reflection model with an electron density of ne ≈ 1020 cm−3 and an iron abundance of $Z_{\rm Fe}=3.2\pm 0.5\, \mathrm{Z}_{\odot }$ is used to fit the broad-band spectra of this source. No additional component is required to fit the soft excess. Our best-fitting model provides consistent measurements of black hole spin and disc inclination angle as previous models where a low disc density was assumed. In the end, we calculate the average illumination distance between the corona and the reflection region in the disc of IRAS 13224−3809 based on best-fitting density and ionization parameters, which changes from 0.43$\sqrt{f_{\rm AD}/f_{\rm INF}}$ rg in the lowest flux state to 1.71$\sqrt{f_{\rm AD}/f_{\rm INF}}$ rg in the highest flux state assuming a black hole mass of $2\times 10^{6}\, \mathrm{M}_{\odot }$. fAD/fINF is the ratio between the flux of the coronal emission that reaches the accretion disc and infinity. This ratio depends on the geometry of the coronal region in IRAS 13224−3809. So we only discuss its value based on the simple ‘lamppost’ model, although detailed modelling of the disc emissivity profile of IRAS 13224−3809 is required in future to reveal the exact geometry of the corona.
Physical link of the polar field buildup with the Waldmeier effect broadens the scope of early solar cycle prediction: Cycle 25 is likely to be slightly stronger than Cycle 24
Authors: Kumar Pawan , Biswas Akash , Karak Bidya Binay 
Published: April 2022

ABSTRACT
Prediction of the solar cycle is challenging but essential because it drives space weather. Several predictions with varying amplitudes of the ongoing Cycle 25 have been made. We show that an aspect of the Waldmeier effect (WE2), i.e. a strong positive correlation between the rise rate and the amplitude of the cycle, has a physical link with the buildup of the previous cycle’s polar field after its reversal. We find that the rise rate of the polar field is highly correlated with the rise rate and the amplitude of the next solar cycle. Thus, the prediction of the amplitude of the solar cycle can be made just a few years after the reversal of the previous cycle’s polar field, thereby extending the scope of the solar cycle prediction to much earlier than the usual time. Our prediction of Cycle 25 based on the rise rate of the previous polar field is 137 ± 23, which is quite close to the prediction 138 ± 26 based on the WE2 computed from the available 2 yr sunspot data of the ongoing cycle.

ABSTRACTObjectivesTo investigate factors associated with frailty in rheumatoid arthritis (RA) patients with decreased renal function.MethodsRA patients who visited outpatient clinics from June to August 2021 were included (N = 625). Patients with estimated glomerular filtration rate &lt;60 ml/min/1.73 m2 were defined as having decreased renal function (N = 221) and divided into the non-frailty (N = 153) and frailty (N = 58) groups. Patient characteristics were compared between the two groups by univariate analysis. Significant factors in univariate analysis were assessed by logistic regression analysis to determine their association with frailty in patients with decreased renal function.ResultsPatients in the frailty group were older (74.0 vs.79.0 years) and had a longer duration of disease (11.1 vs. 17.8 years), higher Disease Activity Score erythrocyte sedimentation rate (DAS28-ESR; 2.99 vs. 3.80), higher Health Assessment Questionnaire Disability Index (0.42 vs. 1.43), and a lower rate of methotrexate (MTX) use (46.4% vs. 25.9) compared to those in the non-frailty group. Factors associated with frailty in patients with decreased renal function were age (odds ratio: 1.07), duration of disease (1.06), DAS28-ESR (1.85), and MTX use (0.42).ConclusionsAmong factors associated with frailty in RA patients with decreased renal function, improving DAS28-ESR is likely to be the most feasible approach to promote recovery from frailty (200/200 words).
Destructive cervical spondylitis due to Cutibacterium acnes with synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome: A case report

ABSTRACT
Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a spectrum of heterogeneous diseases commonly recognised by skin and osteoarticular lesions. There have been reports of some surgical cases of the progressive, destructive spondylitis associated with SAPHO syndrome, wherein the destructive spondylitis was considered to have developed due to the progression of spondylitis with SAPHO syndrome as the pathogenic bacteria were not isolated. We herein report a surgical case of destructive cervical spondylitis associated with SAPHO syndrome. A 54-year-old woman with a history of palmoplantar pustulosis suffered severe neck pain for 6 months. Radiography and computeed tomography showed sclerosed and collapsed cervical vertebrae, and the patient was referred to our hospital for further evaluation and management upon suspicion of infection or spondylitis with SAPHO syndrome. For the severe neck pain and progressive destruction of cervical vertebrae, we performed posterior fusion surgery with subsequent anterior fusion. Cutibacterium acnes (C. acnes) was isolated by enrichment culture with thioglycolate broth from both the anterior and the posterior tissue samples. We diagnosed pyogenic spondylitis secondary to C. acnes infection and administered doxycycline for 6 weeks after the first surgery. The neck pain was resolved and cervical fusion was achieved one year postoperatively. C. acnes infection could elicit destructive spondylitis. An enrichment culture should be performed to isolate the pathogenic bacteria in cases of destructive spondylitis with SAPHO syndrome.
