Decayless low-amplitude transverse oscillations in short coronal loops as manifestations of driven slow modes
Authors: Lopin I , Nagorny I 
Published: November 2023

ABSTRACT
A recent theoretical study of slow magnetoacoustic oscillations in a curved magnetic slab shows that the principal slow mode causes both dominant longitudinal motions and radial (transverse) kink-like motions of a slab. This modification of wave properties occurs due to the violation of the symmetry of wave motions with respect to the waveguide axis and the slow to fast wave interaction in curved magnetic configurations. In this work, we carry out a comprehensive investigation of the principal slow mode depending on the model parameters. It is shown that the dominance of longitudinal motions in the principal slow mode decreases as both the internal plasma-β and slab aspect ratio increase. The results are used to explain the observed small amplitude decayless transverse oscillations in short coronal loops. In particular, these phenomena are interpreted as direct manifestation of slow mode oscillations in curved coronal loops excited at the footpoints by compressible oscillations of the underlying atmospheric layers. Numerical calculations have shown that the observed velocity range of V = 0.6–5 km s−1 corresponds to radial velocity amplitudes in the principal slow mode, provided that the plasma-β inside the short loops is in the range of βi= 0.3–0.5 and the loop aspect ratio 0.15 ≤ a/R ≤ 0.25. These parameters appear to be typical for low-lying small coronal loops extending from the transition region to the lower corona.
Impact of Galactic dust non-Gaussianity on searches for B-modes from inflation

ABSTRACT
A key challenge in the search for primordial B-modes is the presence of polarized Galactic foregrounds, especially thermal dust emission. Power-spectrum-based analysis methods generally assume the foregrounds to be Gaussian random fields when constructing a likelihood and computing the covariance matrix. In this paper, we investigate how non-Gaussianity in the dust field instead affects CMB and foreground parameter inference in the context of inflationary B-mode searches, capturing this effect via modifications to the dust power-spectrum covariance matrix. For upcoming experiments such as the Simons Observatory, we find no dependence of the tensor-to-scalar ratio uncertainty $\sigma (r)$ on the degree of dust non-Gaussianity or the nature of the dust covariance matrix. We provide an explanation of this result, noting that when frequency decorrelation is negligible, dust in mid-frequency channels is cleaned using high-frequency data in a way that is independent of the spatial statistics of dust. We show that our results hold also for non-zero levels of frequency decorrelation that are compatible with existing data. We find, however, that neglecting the impact of dust non-Gaussianity in the covariance matrix can lead to inaccuracies in goodness-of-fit metrics. Care must thus be taken when using such metrics to test B-mode spectra and models, although we show that any such problems can be mitigated by using only cleaned spectrum combinations when computing goodness-of-fit statistics.

Abstract
Intense solar eruptions occasionally trigger extreme geomagnetic storms, expand the boundaries of the auroral oval, and facilitate equatorward extensions of the auroral visibility. It is important to analyse such events, to better understand the extremity of space weather and its impact on the technological infrastructure of the modern civilization. However, unlike other extreme geomagnetic storms, little is known about the auroral activity associated with the extreme geomagnetic storm on 15/16 July 1959, the second largest geomagnetic storm in the space age. This study acquired and analysed two Chinese accounts and one Russian account of auroral visibility at low (≤40°) magnetic latitudes (MLATs). These records allowed us to conservatively reconstruct the equatorward boundaries of the auroral visibility and the auroral oval at 27.4° MLAT and 35.4° invariant latitude, respectively. Our analysis chronologically contextualized these auroral records slightly before the peak of the extreme geomagnetic storm. Moreover, their coloration indicates the excitations of, at least, nitrogen at 427.8 nm and oxygen at 557.7 nm at these low MLATs. Our results allow us to contextualize this extreme geomagnetic storm within other extreme events, based on the equatorward boundary of the auroral oval, thereby facilitating the improvement in existing empirical models for correlations of the auroral extension and the storm intensity.

ABSTRACT
Planetary nebulae (PNe) have long been known to consist of gas, molecules, and dust. The vast majority of the work in which properties of the dust of these objects are inferred were carried out through infrared observations. We use a technique that gives information about the dust, without nebular contamination, and regardless of its temperature. The primary objective is to present an atlas of images with the distribution of dust extinction in PNe. We obtained images in narrow-band filter centred on the nebular emission of the Balmer lines H α and H β to derive extinction images. By combining these images we have been able to achieve the distribution of dust in PNe. The atlas contains 29 PNe, representing the most comprehensive and extensive surveys of dust distribution in PNe.

Abstract

Background
A transplant infectious disease (TID) assessment is essential to select recipients for an allogeneic hematopoietic cell transplant (HCT) and tailor prophylactic and empirical treatment recommendations.

Methods
We performed a retrospective single-center study to describe our model of care based on a routine TID consultation prior to an allogeneic HCT between 2018 and 2022 in 292 adult (≥18-year-old) consecutive patients. We describe the performance of a TID consultation, arbitrarily defined as major (HCT postponement, procedure, cytomegalovirus [CMV] recipient serology reinterpretation) and minor interventions.

Results
Overall, 765 interventions were observed in 257 of 292 (88%) patients: 88 of 765 (11.5%) major and 677 of 765 (88.5%) minor interventions. Among major interventions, HCT was postponed in 8 of 292 (2.7%) patients and a procedure was requested in 18 of 292 (6.2%) patients. The CMV recipient serostatus was changed from indeterminate/low-titer positive to negative in 60 of 292 (20.5%) patients. Among 677 minor interventions, there were 68 (8.8%) additional consultations with other services requested, 260 (33.7%) additional diagnostic tests requested, 102 (13.2%) additional treatments recommended, 60 (7.8%) non-CMV serology reinterpretations performed, 115 (14.9%) deviations from routine anti-infective prophylaxis, and 72 (9.3%) deviations from routine empirical antibiotic treatment recommendations in case of neutropenic fever.

Conclusions
We are proposing a structured, clearly defined, and comprehensive pretransplant checklist for an effective assessment of infectious disease risks and complications prior to an allogeneic HCT. Further studies or experiences like ours could help to define a global strategy or new models of care to be implemented in HCT centers in the future.

Abstract

Introduction
The aim of this systematic review was to summarize the current literature on wearable technologies in oncology patients for the purpose of prognostication, treatment monitoring, and rehabilitation planning.

Methods
A search was conducted in Medline ALL, Cochrane Central Register of Controlled Trials, Embase, Emcare, CINAHL, Scopus, and Web of Science, up until February 2022. Articles were included if they reported on consumer grade and/or non-commercial wearable devices in the setting of either prognostication, treatment monitoring or rehabilitation.

Results
We found 199 studies reporting on 18 513 patients suitable for inclusion. One hundred and eleven studies used wearable device data primarily for the purposes of rehabilitation, 68 for treatment monitoring, and 20 for prognostication. The most commonly-reported brands of wearable devices were ActiGraph (71 studies; 36%), Fitbit (37 studies; 19%), Garmin (13 studies; 7%), and ActivPAL (11 studies; 6%). Daily minutes of physical activity were measured in 121 studies (61%), and daily step counts were measured in 93 studies (47%). Adherence was reported in 86 studies, and ranged from 40% to 100%; of these, 63 (74%) reported adherence in excess of 80%.

Conclusion
Wearable devices may provide valuable data for the purposes of treatment monitoring, prognostication, and rehabilitation. Future studies should investigate live-time monitoring of collected data, which may facilitate directed interventions.

Abstract
Caspases are restricted to animals, while other organisms, including plants, possess metacaspases (MCAs), a more ancient and broader class of structurally related yet biochemically distinct proteases. Our current understanding of plant MCAs is derived from studies in streptophytes, and mostly in Arabidopsis (Arabidopsis thaliana) with 9 MCAs with partially redundant activities. In contrast to streptophytes, most chlorophytes contain only 1 or 2 uncharacterized MCAs, providing an excellent platform for MCA research. Here we investigated CrMCA-II, the single type-II MCA from the model chlorophyte Chlamydomonas (Chlamydomonas reinhardtii). Surprisingly, unlike other studied MCAs and similar to caspases, CrMCA-II dimerizes both in vitro and in vivo. Furthermore, activation of CrMCA-II in vivo correlated with its dimerization. Most of CrMCA-II in the cell was present as a proenzyme (zymogen) attached to the plasma membrane (PM). Deletion of CrMCA-II by genome editing compromised thermotolerance, leading to increased cell death under heat stress. Adding back either wild-type or catalytically dead CrMCA-II restored thermoprotection, suggesting that its proteolytic activity is dispensable for this effect. Finally, we connected the non-proteolytic role of CrMCA-II in thermotolerance to the ability to modulate PM fluidity. Our study reveals an ancient, MCA-dependent thermotolerance mechanism retained by Chlamydomonas and probably lost during the evolution of multicellularity.

Abstract
Photosynthetic organisms harvest light using pigment–protein complexes. In cyanobacteria, these are water-soluble antennae known as phycobilisomes (PBSs). The light absorbed by PBS is transferred to the photosystems in the thylakoid membrane to drive photosynthesis. The energy transfer between these complexes implies that protein–protein interactions allow the association of PBS with the photosystems. However, the specific proteins involved in the interaction of PBS with the photosystems are not fully characterized. Here, we show in Synechocystis sp. PCC 6803 that the recently discovered PBS linker protein ApcG (sll1873) interacts specifically with PSII through its N-terminal region. Growth of cyanobacteria is impaired in apcG deletion strains under light-limiting conditions. Furthermore, complementation of these strains using a phospho-mimicking version of ApcG causes reduced growth under normal growth conditions. Interestingly, the interaction of ApcG with PSII is affected when a phospho-mimicking version of ApcG is used, targeting the positively charged residues interacting with the thylakoid membrane, suggesting a regulatory role mediated by phosphorylation of ApcG. Low-temperature fluorescence measurements showed decreased PSI fluorescence in apcG deletion and complementation strains. The PSI fluorescence was the lowest in the phospho-mimicking complementation strain, while the pull-down experiment showed no interaction of ApcG with PSI under any tested condition. Our results highlight the importance of ApcG for selectively directing energy harvested by the PBS and imply that the phosphorylation status of ApcG plays a role in regulating energy transfer from PSII to PSI.

Abstract
The origin of life on Earth is an enigmatic and intricate conundrum that has yet to be comprehensively resolved despite recent significant developments within the discipline of archaeology and geology. Chemically, metal-sulfide minerals are speculated to serve as an important medium for giving birth in early life, while yet so far direct evidence to support the hypothesis for the highly efficient conversion of inorganic carbon into praxiological biomolecules remains scarce. In this work, we provide an initial indication that sphalerite, employed as a typical mineral, shows its enormous capability for promoting the conversion of inorganic carbon into elementary biomolecule formic acid (HCOOH) in airborne mineral-bearing aerosol microdroplet, which is over two orders of magnitude higher than that of the corresponding conventional bulk-like aqueous phase medium in the environment (e.g. river, lake, sea, etc.). This significant enhancement was further validated by a wide range of minerals and clays, including CuS, NiS, CoS, CdS, MnS, elemental sulfur, Arizona Test Dust, loess, nontronite, and montmorillonite. We reveal that the abundant interface of unique physical–chemical features instinct for aerosol or cloud microdroplets reduces the reaction energy barrier for the reaction, thus leading to extremely high HCOOH production (2.52 × 1014 kg year−1). This study unfolds unrecognized remarkable contributions of the considered scheme in the accumulation of prebiotic biomolecules in the ancient period of the Earth.
Seasonal patterns of communicable disease incidence and antibiotic prescribing in Moria refugee camp, Greece
Authors: Simonek Tomas , Zahos Helen , Mahroof-Shaffi Siyana , Harkensee Christian 
Published: November 2023

Abstract

Background
Infectious diseases remain a major risk for refugees living in camps. Limited research has been undertaken into the burden and impact of infections in the current refugee crisis around the Mediterranean.
This analysis examines the frequency and incidence rates of common infections, and use of antibiotics at a healthcare facility inside Moria refugee camp on the island of Lesvos, Greece, during the winter and summer seasons of 2019.

Methods
This is a retrospective analysis of routinely, prospectively collected service data from the main acute healthcare facility inside Moria camp.

Results
Of a total of 9601 consultations, 25.16% were for infections (winter: 31.53%, summer: 19.45%). Respiratory, skin and gastrointestinal infections were the most frequent, with incidence rates up to 3.5 times, 50 times and twice as high as those in Western Europe, respectively. Antibiotic prescribing was high (27.7% of all respiratory infections) with high use of broad-spectrum antibiotics (40.2%), raising concerns about induction of antimicrobial resistance.

Conclusions
The burden of infectious diseases in refugee camps remains high throughout all seasons. Antimicrobial stewardship programmes should be adapted to refugee camp settings to prevent the development of unnecessary antimicrobial resistance. Improving living conditions and access to healthcare in refugee camps is likely to reduce infection rates and antimicrobial resistance among refugees.

A New Value Strategy
Authors: Wang Baolian 
Published: November 2023

Abstract
Traditional value measures performed poorly over the past three decades. We reevaluate the value strategy using a new measure—the ratio of cash-based operating profitability to price (COP/P)—and find a zero-investment portfolio that buys the highest-COP/P stocks and shorts the lowest-COP/P stocks earns monthly returns of 0.78% on a value-weighted basis and 1.04% on an equal-weighted basis. The COP/P effect holds even for large-capitalization stocks and exists even in the post-1990 period, when book-to-market does not predict returns. The COP/P measure subsumes many widely used value measures and the conservative-minus-aggressive investment factor. (JEL G02, G12)
Drivers of eco-innovation: the role of appropriability strategies and complementary assets
Authors: Orjuela-Ramirez Guillermo , Zuluaga-Jimenez Julio Cesar , Urbano David 
Published: November 2023

Abstract
How do eco-innovators protect and profit from their innovations so they have the incentive to undertake an innovation in the first place? The double externality nature of environmental innovations intricates this appropriability problem, as competitors and society might also benefit from the value created by eco-innovation. Based on David Teece’s Profiting from innovation framework, we argue that firms combine appropriability strategies such as patents, industrial secrecy, and complex design with the development of complementary assets to incentivize and secure rent appropriation from eco-innovation. We estimate that formal appropriability mechanisms increase the probability of developing an eco-innovation by 6 per cent, while informal mechanisms increase it by about 15 per cent. Our panel data regression model demonstrates that marketing capability enhances the effect of appropriability mechanisms by differentiating eco-innovation from other technologies. However, this complementarity differs as a firm increases marketing investments, especially in small and Research and Development R&D publicly financed firms.
Reduced REM and N2 sleep, and lower dream intensity predict increased mind-wandering

Published: November 2023

Abstract
Mind-wandering is a mental state in which attention shifts from the present environment or current task to internally driven, self-referent mental content. Homeostatic sleep pressure seems to facilitate mind-wandering as indicated by studies observing links between increased mind-wandering and impaired sleep. Nevertheless, previous studies mostly relied on cross-sectional measurements and self-reports. We aimed to combine the accuracy of objective sleep measures with the use of self-reports in a naturalistic setting in order to examine if objective sleep parameters predict the tendency for increased mind-wandering on the following day. We used mobile sleep electroencephalographic (EEG) headbands and self-report scales over 7 consecutive nights in a group of 67 healthy participants yielding ~400 analyzable nights. Nights with more wakefulness and shorter REM and slow wave sleep were associated with poorer subjective sleep quality at the intraindividual level. Reduced REM and N2 sleep, as well as less intense dream experiences, predicted more mind-wandering the following day. Our micro-longitudinal study indicates that intraindividual fluctuations in the duration of specific sleep stages predict the perception of sleep quality as assessed in the morning, as well as the intensity of daytime mind-wandering the following hours. The combined application of sleep EEG assessments and self-reports over repeated assessments provides new insights into the subtle intraindividual, night-to-day associations between nighttime sleep and the next day’s subjective experiences.

Abstract

Background
The mainstay of soil-transmitted helminth (STH) control is repeated mass drug administration (MDA) of anthelmintics to endemic populations. Individual longitudinal compliance treatment patterns are important for identifying pockets of infected individuals who remain untreated and serve as infection reservoirs.

Methods
The Geshiyaro Project censused the study population in Wolaita, Ethiopia at baseline in 2018. Individual longitudinal compliance was recorded for six rounds of community-wide MDA (cMDA). The probability distribution of treatment frequency was analysed by age and gender stratifications. Probabilities of transmission interruption for different compliance patterns were calculated using an individual-based stochastic model of Ascaris lumbricoides transmission.

Results
The never-treated (0.42%) population was smaller than expected from a random positive binomial distribution. The observed compliance frequency was well described by the beta-binomial distribution. Preschool-age children (odds ratio [OR] 10.1 [95% confidence interval {CI} 6.63 to 15.4]) had the highest never-treated proportion of the age groups. Conversely, school-age children (SAC) and adults (OR 1.03 [95% CI 0.98 to 1.09]) had the highest always-treated proportion of the age groups.

Conclusions
The study reports the largest dataset of individual longitudinal compliance to cMDA for STH control. Clear pattens are shown in the age-dependent distribution of individual compliance behaviour. The impact of compliance on the probability of elimination is significant, highlighting the importance of recording the full frequency distribution, not just the never-treated proportion.
