Living with Neighbors. IV. Dissecting the Spin–Orbit Alignment of Dark Matter Halos: Interacting Neighbors and the Local Large-scale Structure
Authors: An Sung-Ho , Kim Juhan , Moon Jun-Sung , Yoon Suk-Jin 
Published: June 2021

Abstract
Spin–orbit alignment (SOA; i.e., the vector alignment between the halo spin and the orbital angular momentum of neighboring halos) provides an important clue to how galactic angular momenta develop. For this study, we extract virial-radius-wise contact halo pairs with mass ratios between 1/10 and 10 from a set of cosmological N-body simulations. In the spin–orbit angle distribution, we find a significant SOA in that 52.7% ± 0.2% of neighbors are on the prograde orbit. The SOA of our sample is mainly driven by low-mass target halos (<1011.5
h

M
⊙) with close merging neighbors, corroborating the notion that tidal interaction is one of the physical origins of SOA. We also examine the correlation of SOA with the adjacent filament and find that halos closer to the filament show stronger SOA. Most interestingly, we discover for the first time that halos with the spin parallel to the filament experience most frequently prograde polar-interaction (i.e., fairly perpendicular but still prograde interaction; spin–orbit angle ∼70°). This instantly invokes the spin-flip event and the prograde-polar interaction will soon flip the spin of the halo to align it with the neighbor’s orbital angular momentum. We propose that SOA originates from the local cosmic flow along the anisotropic large-scale structure, especially that along the filament, and grows further by interactions with neighbors.
Compressive Oscillations in Hot Coronal Loops: Are Sloshing Oscillations and Standing Slow Waves Independent?
Authors: Prasad S. Krishna , Van Doorsselaere T. 
Published: June 2021

Abstract
Employing high-resolution EUV imaging observations from SDO/AIA, we analyze a compressive plasma oscillation in a hot coronal loop triggered by a C-class flare near one of its footpoints, as first studied by Kumar et al. We investigate the oscillation properties in both the 131 Å and 94 Å channels and find that what appears as a pure sloshing oscillation in the 131 Å channel actually transforms into a standing wave in the 94 Å channel at a later time. This is the first clear evidence of such transformation and confirms the results of a recent numerical study that suggests that these two oscillations are not independent phenomena. We introduce a new analytical expression to properly fit the sloshing phase of an oscillation and extract the oscillation properties. For the AIA 131 Å channel, the obtained oscillation period and damping time are 608 ± 4 s and 431 ± 20 s, respectively, during the sloshing phase. The corresponding values for the AIA 94 Å channel are 617 ± 3 s and 828 ± 50 s. During the standing phase that is observed only in the AIA 94 Å channel, the oscillation period and damping time have increased to 791 ± 5 s and 1598 ± 138 s, respectively. The plasma temperature obtained from the differential emission measure analysis indicates substantial cooling of the plasma during the oscillation. Considering this, we show that the observed oscillation properties and the associated changes are compatible with damping due to thermal conduction. We further demonstrate that the absence of a standing phase in the 131 Å channel is a consequence of cooling plasma besides the faster decay of oscillation in this channel.
The Evolution of the Ultraluminous Lyα Luminosity Function over z = 5.7–6.6

Published: June 2021

Abstract
Ultraluminous Lyα emitting galaxies (ULLAEs) with

erg s−1 near the epoch of reionization (z > 5) make up the bright end of the LAE luminosity function (LF) and may provide insight into the process of reionization, including the formation of ionized bubbles around these extreme systems. We present a spectroscopic LF for ULLAEs at z = 5.7. We used data from the HEROES ∼45 deg2 Subaru Hyper Suprime-Cam survey, which is centered on the North Ecliptic Pole and has both broadband (grizY) and narrowband (NB816 and NB921) imaging, to select candidate ULLAEs based on a NB816 excess and a strong broadband Lyman break. We spectroscopically observed 17 ULLAE candidates with DEIMOS on Keck II. We confirmed 12 as LAEs at z = 5.7, 9 of which are ULLAEs. The remaining sources are an active galactic nuclei at z = 5.7, an [O III]λ5007 emitter at z = 0.63, a red star, and two spectroscopic nondetections. Using the nine confirmed ULLAEs, we construct a ULLAE LF at z = 5.7. After applying a comprehensive incompleteness correction, we compare our new z = 5.7 LF with our recent z = 6.6 LF and with other LFs from the literature to look for evolution at the ultraluminous end. We find the overall ratio of the z = 5.7 to z = 6.6 ULLAE comoving number densities to be

, which corresponds to an LF offset of

dex.

Abstract
A small number of anomalously bright boulders on the near-Earth rubble-pile asteroid (101955) Bennu were recently identified as eucritic material originating from asteroid (4) Vesta. Building on this discovery, we explored the global presence of exogenic boulders on Bennu. Our analysis focused on boulders larger than 1 m that show the characteristic 1 μm pyroxene absorption band in the four-color MapCam data from the OSIRIS-REx mission. We confirm the presence of exogenic boulders similar to eucrites and find that a mixture of eucrite with carbonaceous material is also a possible composition for some boulders. Some of the exogenic boulders have spectral properties similar to those of ordinary chondrite (OC) meteorites, although the laboratory spectra of these meteorites have a higher albedo than those measured on Bennu, which could be explained by either a grain size effect, the presence of impact melt, or optical mixing with carbonaceous material owing to dust coating. Our Monte Carlo simulations predict that the median amount of OC mass added to the parent body of Bennu is 0.055% and 0.037% of the volume of a 100 and 200 km diameter parent body, respectively. If Bennu was a uniformly mixed by-product of parent body and S-type projectiles, the equivalent mass of OC material would be a sphere with a diameter of 36–40 m (or a volume of 24,200–33,600 m3). The total amount of OC material in the interior of Bennu estimated from the MapCam data is slightly higher (91,000–150,000 m3).

Published: June 2021

Background: Peer review is a necessary but costly and time-consuming process to identify good-quality and methodologically sound articles and improve them before publication. Finding good peer reviewers is often difficult.
Objective: To identify the incentives that make Iranian biomedical researchers accept invitations to be a peer reviewer and factors that affect these incentives.
Methods: Twelve reviewers selected at random from the reviewers pool of each of 26 biomedical journals published from Fars province, Iran, were surveyed using a questionnaire that we had developed and tested in a pilot study of 30 reviewers (Cronbach&rsquo;s alpha of 0.779). The data included the reviewers&rsquo; demographics, history of their reviews, and choice of 11 reasons each for accepting or declining the invitation to review.
Results: A total of 233 reviewers completed the questionnaire. The most important reasons for accepting the invitation to review were the journal&rsquo;s practice to publish the names of the reviewers alongside the article they had reviewed, acknowledgement by the journals by publishing the names of reviewers once a year, free access to journals&rsquo; content, and lower publication charges as authors. The most common reasons to decline the invitation were lack of time, busy schedules, and lack of sufficient incentive to review.
Conclusion: Acknowledgement by the journal, offering to publish the names of reviewers alongside the articles they had reviewed, and monetary rewards will be effective incentives for biomedical researchers in Iran to serve as peer reviewers.
Pertes et deuil des acteurs de la digitalisation : le cas de l’automatisation des caisses dans la grande distribution suisse
Authors: Audrin Bertrand , Davoine Eric , Métraux Jean-Claude 
Published: June 2021

Cette étude mobilise le cadre conceptuel du deuil et des pertes pour comprendre les réactions des acteurs organisationnels dans un contexte de changement digital. La recherche empirique se base sur une double étude de cas auprès des deux leaders du marché de la grande distribution suisse ayant mis en œuvre des systèmes d’encaissement automatique (technologies en libre-service), avec un corpus de 8 entretiens avec des managers, 12 entretiens avec des caissières et 75 entretiens avec des clients. L’étude permet d’identifier différents types de pertes perçues par les trois groupes d’acteurs concernés par la digitalisation. Alors que les managers vont surtout concevoir le changement numérique avec une perspective de gains de productivité, les employé.e.s et les client.e.s expriment des pertes symboliques susceptibles de déclencher des processus de deuil : des pertes d’identité et de repères professionnels, des pertes de relation et de qualité d’interaction, ainsi que des pertes de sens liées au changement d’image ‘modernisée’ et ‘rationnalisée’ des coopératives de la distribution suisse et de la qualité de lien associée à l’échange commercial. Cette perspective permet une meilleure compréhension de ce que signifie le changement numérique pour différentes catégories d’acteurs. En intégrant les clients à titre d’« employés partiels », nous identifions les enjeux spécifiques de cette catégorie d’acteurs dans le changement digital. Sur la base de notre analyse, nous pouvons recommander d’intégrer plus systématiquement des parties prenantes comme les clients dans les processus de sensemaking du changement digital.

Authors: Oguntona O.A. , Aigbavboa C.O. , Thwala W.D. 
Published: June 2021

ABSTRACTOwing to the adverse impact of the architecture, engineering and construction industry on the human and natural environment, the adoption of green building (GB) has been on the rise globally. The significant rise in the number of global research output on GB is a pointer to its proliferation. In this paper, a novel scientometric analysis of GB research in Africa is presented. This study aims to analyze and visualize GB research output in Africa from the millennium development goals (MDGs) era up to the present sustainable development goals (SDGs) era. A quantitative method (science mapping) was employed to analyze the 156 bibliometric records gathered from the Scopus database. An analysis of the dataset reveals that significant contributions to GB research in Africa originate from Egypt, South Africa, Nigeria, Algeria, Ghana, Morocco, Kenya, Mauritius, Ethiopia and Cameroon. This research provides stakeholders in the built environment with the requisite knowledge and understanding of the trend and state of GB research in Africa, which will help in guiding policymaking, research directions and intervention areas in every sector of the economy.

Face à la congestion croissante et les impacts négatifs sur la santé, l’environnement et les espaces publics du « tout à la voiture », la marche gagne depuis quelques années de l’importance dans les débats et les esprits. Afin de promouvoir la pratique à Bruxelles, Bruxelles Mobilité a réalisé un diagnostic des espaces publics, à travers les plans d’accessibilité de la voirie et de l’espace public [PAVE]. La recherche dont est tirée le présent article complète ce diagnostic en identifiant le spectre large des gênes au déplacement piéton et les variations de leur appréhension. Pour ce faire, plusieurs méthodologies distinctes ont été combinées (analyse spatiale et morphologique, analyse des flux et comportements piétons, parcours commentés auprès de personnes à mobilité réduite), permettant ainsi d’élaborer une vision dynamique du déplacement piéton et des gênes qui peuvent l’affecter. Sur cette base, plusieurs pistes de solution sont formulées pour arriver à un équilibre entre besoins de fluidité de déplacement, ralentissements des flux piétons et expérience de la marche.

‘Breathful’ design in breathless times
Authors: Wernli Markus , Boyer Britta 
Published: June 2021

This position paper seeks to address the operational logic that created the conditions for the pandemic to take hold. Grasping the crisis as an opportunity for an anthropological inquiry across disciplines, this exploration firmly anchors design inside the social commitment required by breathing bodies and life-enabling atmospheres. By infusing the self-understanding of design with experiences and conceptions from Eastern and Western ‘breathwork’ practices the adaptation strategy in uncertainty shifts from perpetuating the status quo towards the creative reinterpretation of internal priorities. It also changes the nature of our projects, from making to enacting, from preprogrammed solutions to earthly engagement, from interfacing with inert matter to caring for living matters. Taking our universally shared breath as the resounding call for action, ‘breathful’ design is about the never-finished, perpetually opening task of persisting through bodily vigilance, diligence, and self-critical forsight for ‘knowing what to do when no one knows what to do’.
Two adventive species of European Chrysomelidae (Coleoptera) new to North America:Cryptocephalus moraei(Cryptocephalinae) andPsylliodes dulcamarae(Galerucinae: Alticini), and the origins of adventive Chrysomelidae in Canada and United States of America

Published: June 2021

AbstractFirst North American records are presented forCryptocephalus moraei(Linnaeus, 1758) (Coleoptera: Cryptocephalinae) andPsylliodes dulcamarae(Koch, 1803) (Coleoptera: Galerucinae: Alticini), as confirmed by morphology and DNA barcoding. Additional information is presented about phenology and host use forC. moraei, the first European Cryptocephalinae to be found elsewhere as conclusively adventive.Cryptocephalus moraeiis expected to have no ecological impact on its host, the adventiveHypericum perforatumLinnaeus (Hypericaceae). However,P. dulcamarae,the second recently discovered flea beetle associated with the adventiveSolanum dulcamaraLinnaeus (Solanaceae), probably does harm that host. Both species are hypothesised to have arrived from Europe with woody plant material imported with soil during 1960–1965. A literature review of introduced Chrysomelidae found that Canada and the United States of America are together home to 68–78 species of adventive Chrysomelidae. All non-Bruchinae species among these are both native to Europe and occur either in Canada or both Canada and United States of America, except for intentionally introduced biological control agents and two species that feed onEucalyptusL’Héritier de Brutelle (Myrtaceae). This suggests a dominant role of accidental introductions of cool-climate European species in recent unplanned additions to the fauna of leaf-feeding Chrysomelidae in North America.

Abstract
Lasting immunity will be critical for overcoming COVID-19. However, the factors associated with the development of high titers of anti–SARS-CoV-2 Abs and how long those Abs persist remain incompletely defined. In particular, an understanding of the relationship between COVID-19 symptoms and anti–SARS-CoV-2 Abs is limited. To address these unknowns, we quantified serum anti–SARS- CoV-2 Abs in clinically diverse COVID-19 convalescent human subjects 5 wk (n = 113) and 3 mo (n = 79) after symptom resolution with three methods: a novel multiplex assay to quantify IgG against four SARS-CoV-2 Ags, a new SARS-CoV-2 receptor binding domain-angiotensin converting enzyme 2 inhibition assay, and a SARS-CoV-2 neutralizing assay. We then identified clinical and demographic factors, including never-before-assessed COVID-19 symptoms, that consistently correlate with high anti–SARS-CoV-2 Ab levels. We detected anti–SARS-CoV-2 Abs in 98% of COVID-19 convalescent subjects 5 wk after symptom resolution, and Ab levels did not decline at 3 mo. Greater disease severity, older age, male sex, higher body mass index, and higher Charlson Comorbidity Index score correlated with increased anti–SARS-CoV-2 Ab levels. Moreover, we report for the first time (to our knowledge) that COVID-19 symptoms, most consistently fever, body aches, and low appetite, correlate with higher anti–SARS-CoV-2 Ab levels. Our results provide robust and new insights into the development and persistence of anti–SARS-CoV-2 Abs.

Published: June 2021

Background Since the first case of Coronavirus Disease 2019 (COVID-19) in Italy, all the hospital facilities had to reform their daily activities. Amidst them, the Interventional Radiology Department in the “Azienda Ospedaliera Universitaria” of Novara (Italy) had to create a dedicated protocol for the patent's management during the pandemic. Design and methods The time interval between February 2020 and March 2021 was divided into three different periods and we reported the evolution of our safety protocol, the changes in our daily activities and the rates of SARS-CoV-2 infection among the healthcare workers (HCW) of the Angiographic Suite. Personnel who had positive partners/family members or who had established close contacts of another nature outside the workplace were excluded from the study, in order to reduce any bias. Results A total of 35 HCWs served in 355 patient procedures on SARS-CoV-2 positive patients from February 2020 to March 2021. During the year there was a reduction in the morbidity rate first from 7.9% to 1.4% and then currently reaching 0%. Conclusions Dedicated routes, elevators, establishing filter areas and a clear demarcation between clean and contaminated areas, dressing and undressing procedures, cleaning procedures and the obligation to always wear a surgical mask during the working shift are essential to prevent in-hospital infection. The vaccines’ arrival seems to further reduce the risk for healthcare workers, but it is still necessary to take docile precautions in view of the new mutations of the virus.
Medication Adherence in Indian Epilepsy Patients
Authors: Kumar Shrawan , Singh Mamta Bhushan , Kumar Amit , Padma Srivastava M V , Goyal Vinay 
Published: June 2021

Purpose:
While two-thirds of epilepsy patients can become seizure free on medical treatment, poor adherence to medication is a major problem to sustained remission and functional restoration. The aim of this study was to assess the prevalence and associated factors of antiepileptic drug (AED) non-adherence.

Methods:
We conducted a subgroup analysis based on results that emerged from a single center, cross-sectional study. Patients who were 18 years or older were included. The 4-item Morisky Medication Adherence Scale was used to measure adherence to AED (s). Multivariable logistic regression analysis was used to predict factors associated with AED non-adherence.

Results:
A total of 268 patients fulfilled inclusion criteria and were included in this subgroup analysis. Among the participants, 81 (30%) were non-adherent to medication. Three factors associated with non-adherence were AED polytherapy [OR: 4.5 (2.1-9.5) P = 0.001], drug related adverse events [OR: 3.9 (2.1-7.3) P = 0.001], and treatment duration exceeding 3 years [OR: 2.6 (1.3-5.0) P = 0.003].

Conclusion:
About one-third patients were not compliant with their medication. If the treatment of patients is restricted to monotherapy as far as possible and patients are educated about duration of treatment and possible adverse effects of AEDs, non-adherence may be reduced.
