Abstract
We report the independent discovery of PSR J0026-1955 with the Murchison Widefield Array (MWA) in the ongoing Southern-sky MWA Rapid Two-metre pulsar survey. J0026-1955 has a period of ∼1.306 s, a dispersion measure of ∼20.869 pc cm−3, and a nulling fraction of ∼77%. This pulsar highlights the advantages of the survey's long dwell times (∼80 minutes), which, when fully searched, will be sensitive to the expected population of similarly bright, intermittent pulsars with long nulls. A single-pulse analysis in the MWA's 140–170 MHz band also reveals a complex subpulse drifting behavior, including both rapid changes of the drift rate characteristic of mode switching pulsars, as well as a slow, consistent evolution of the drift rate within modes. In some longer drift sequences, interruptions in the otherwise smooth drift rate evolution occur preferentially at a particular phase, typically lasting a few pulses. These properties make this pulsar an ideal test bed for prevailing models of drifting behavior such as the carousel model.

Abstract
Utilizing high-resolution data from the Magnetospheric Multiscale mission, we present new observations of lower-hybrid drift waves (LHDWs) in terrestrial magnetotail reconnection with guide field levels of ∼70% and asymmetric plasma density (N
high/N
low ∼ 2.5). The LHDWs, driven by lower-hybrid drift instability, were observed in correlation with magnetic field and density gradients at separatrices on both sides of the reconnection current sheet. The properties of the LHDWs at both sides of the separatrices are different: (1) At high-density side separatrices, the LHDWs with wavelength kρ
e ∼ 0.41 propagated away from the X-line mainly in the L–M plane; (2) at the low-density side separatrices, the LHDWs with wavelengths kρ
e ∼ 0.76 and kρ
e ∼ 0.35 propagated mainly along the outflow direction and current sheet normal. It is also found that the perpendicular magnetic field fluctuations were comparable to the parallel component. Wave potential of the LHDWs was 20% ∼ 35% of the electron temperature. The LHDWs contributed to electron demagnetization and energy dissipation. Our study can promote understanding of properties of LHDWs during magnetic reconnection.
The Isotropic γ-ray Emission above 100 GeV: Where Do Very High-energy γ-rays Come From?

Published: July 2022

Abstract
Astrophysical sources of very high energy (VHE; >100 GeV) γ-rays are rare, since GeV and TeV photons can be only emitted in extreme circumstances involving interactions of relativistic particles with local radiation and magnetic fields. In the context of the Fermi Large Area Telescope (LAT), only a few sources are known to be VHE emitters, where the largest fraction belongs to the rarest class of active galactic nuclei: the blazars. In this work, we explore Fermi-LAT data for energies >100 GeV and Galactic latitudes b > ∣50°∣ in order to probe the origin of the extragalactic isotropic γ-ray emission. Since the production of such VHE photons requires very specific astrophysical conditions, we would expect that the majority of the VHE photons from the isotropic γ-ray emission originate from blazars or other extreme objects like star-forming galaxies, γ-ray bursts, and radio galaxies, and that the detection of a single VHE photon at the adopted Galactic latitudes would be enough to unambiguously trace the presence of such a counterpart. Our results suggest that blazars are, by far, the dominant class of sources above 100 GeV, although they account for only

The missing anatomy of the living coelacanth, Latimeria chalumnae (Smith, 1939)
Authors: Johnston Peter 
Published: July 2022

Anatomical features that have not been previously described in Latimeria were sought in histological section series, tissue-stained microCT scans, MRI scans, and synchrotron scan series. The spiracular organ, ultimobranchial endocrine gland, and m. cucullaris were identified in the expected locations. In addition, a muscle arising on the medial side of the pectoral girdle is identified and compared with a muscle in a similar location that attaches to the cranial rib in lungfish; these are proposed as homologues of the tetrapod m. omohyoideus.
These findings are placed in evolutionary context by comparison with selected other groups of fish, lungfish and tetrapods. The position of Latimeria as a key taxon in the fish-to-tetrapod transition is emphasised by these findings, and the findings have potential to inform research on cranial structure in extinct taxa.

ObjectiveWhile myocardial impairment is a predictor of poor prognosis in antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV), little is known about valvular involvement. This study aims at describing the clinical presentation, management, and outcome of endocarditis associated with AAV.MethodsWe conducted a multicenter retrospective study in centers affiliated with the French Vasculitis Study Group. We included patients with granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA), or eosinophilic GPA with endocardial impairment. A systematic review was then performed through PubMed, Embase, and Cochrane Library from inception up to September 2020.ResultsThe retrospective cohort included 9 patients (82%) with GPA, 1 (9%) with MPA, and 1 (9%) with unclassified AAV. Clinical presentation included acute valvular insufficiency (n = 7, 64%), cardiac failure (n = 3, 27%), dyspnea (n = 3, 27%), and no symptoms (n = 2, 18%). The aortic valve was the most frequently affected (n = 8/10, 80%), and vegetations were noted in 4 of 10 patients (40%). Six patients (55%) underwent surgical valvular replacement. No death from endocarditis was reported. The systematic review retrieved 42 patients from 40 references: 30 (71%) had GPA, 21 (50%) presented with vegetations, the aortic valve (n = 26, 62%) was the most frequently involved. Valvular replacement was required in 20 cases (48%) and 5 patients (13%) died from the endocarditic impairment.ConclusionEndocarditis is a rare and potentially life-threatening manifestation of AAV. Acute valvular insufficiency may lead to urgent surgery. Implementing transthoracic echocardiography in standard assessment at baseline and follow-up of AAV might reduce the delay to diagnosis and allow earlier immunosuppressive treatment before surgery is needed.

Researching Social Movements: Methodological Choice
Authors: Harutyunyan Gayane 
Published: July 2022

In the second half of the 19th century, the world was confronted with large-scale social movements, which changed the relations between the citizen and the state once and for all. Particularly, the emergence of the Suffragette movement, then Vietnam’s anti-war movement, as well as the influence of many other smaller, local, short-term social movements, raised new questions for the scientific community. How to study social movements? Which method is more convenient and how to apply it? What kind of knowledge can be developed by studying social movements, how can society benefit from that knowledge? There are many answers to these questions, which are contradictory even today.
This article is an attempt to present the features of the main sociological methods of studying social movements, which play a key role in the exploration of the phenomenon. The article discusses the peculiarities of such research methods as observation, case study, grounded theory, survey and analysis of documents from the perspective of studying social movements.

Particle size distribution and particulate matter concentrations during synoptic and convective dust events in West Texas
Authors: Ardon-Dryer Karin , Kelley Mary C. 
Published: July 2022

Abstract. Dust events are an important and complex constituent of the
atmospheric system that can impact Earth's climate, the environment, and
human health. The frequency of dust events in the Southern High Plains of West Texas has increased over
the past 2 decades, yet their impact on air quality in this region is
still unclear. This is due to the fact that there is only one air quality monitoring station that
measures only PM2.5 concentrations (particulate matter with
an aerodynamic diameter < 2.5 µm), and there is no information on
other PM sizes or the particle size distribution. The Aerosol Research
Observation Station (AEROS) unit provides insight into the local variation
in particle concentration during different dust events and allows for a
better understanding of the impact of dust events on air quality. As this area is prone to dust events, we were wondering if dust events
generated by different meteorological causes (synoptic vs. convective) would
present similar particle concentrations or particle size distributions. Thus, in
this project, three different dust events were measured by AEROS and
compared. Each dust event originated from a different direction and lasted a
different duration. One of the dust events was synoptic (10 April 2019) and
two were convective (5 and 21 June 2019). Measurements of particle mass and
number concentration, size distribution, and meteorological conditions for
each dust event were compared. The synoptic dust event (on 10 April) was
longer (12 h) and had stronger wind speed conditions (up to 22.1 m s−1), whereas the two respective convective dust events on 5 and 21 June lasted only 20 and 30 min and had lower wind speeds (up to 16.5 and 13.4 m s−1). Observation of PM based on daily and hourly values
showed an impact on air quality, yet measurements based on daily and hourly
values underestimate the impact of the convective dust events. Observations
based on a shorter timescale (10 min) reveal the true impact of the two
convective dust events. A comparison of the particle size distribution showed
that all three dust events presented an increase in particles in the 0.3–10 µm size range. Comparisons of the particle concentration for particles
> 5 and > 10 µm show very high
values during the dust events. Some particle sizes even
increase in concentration by ∼ 2 orders of magnitude compared
with the time before the dust event. This leads us to speculate that the impact
of convective dust events on air quality in this region is underestimated
with the current (hourly basis) method.

Abstract. In this paper we present EMO-5 (“European Meteorological Observations”, spatial resolution of 5 km), a European high-resolution, (sub-)daily, multi-variable
meteorological dataset built on historical and real-time observations
obtained by integrating data from 18 964 ground weather stations, four
high-resolution regional observational grids (i.e. CombiPrecip, ZAMG – INCA,
EURO4M-APGD, and CarpatClim), and one global reanalysis
(ERA-Interim/Land). EMO-5 includes the following at daily resolution: total precipitation,
temperatures (minimum and maximum), wind speed, solar radiation, and water
vapour pressure. In addition, EMO-5 also makes available 6-hourly
precipitation and mean temperature data. The raw observations from the ground
weather stations underwent a set of quality controls before SPHEREMAP and
Yamamoto interpolation methods were applied in order to estimate for each
5×5 km grid cell the variable value and its affiliated uncertainty,
respectively. The quality of the EMO-5 precipitation data was evaluated
through (1) comparison with two regional high-resolution datasets (i.e.
seNorge2 and seNorge2018), (2) analysis of 15 heavy precipitation events,
and (3) examination of the interpolation uncertainty. Results show that
EMO-5 successfully captured 80 % of the heavy precipitation events, and
that it is of comparable quality to a regional high-resolution dataset. The
availability of the uncertainty fields increases the transparency of the
dataset and hence the possible usage. EMO-5 (version 1) covers the time
period from 1990 to 2019, with a near real-time release of the latest
gridded observations foreseen with version 2. As a product of Copernicus,
the EU's Earth Observation Programme, the EMO-5 dataset is free and open, and
can be accessed at https://doi.org/10.2905/0BD84BE4-CEC8-4180-97A6-8B3ADAAC4D26 (Thiemig et

Authors: Astudillo Mariño Nicolay , Erazo Noguera Patricia Cecilia 
Published: July 2022

Introducción: La atrofia muscular espinal, la principal causa genética de muerte infantil, es un conjunto heterogéneo de enfermedades que se caracterizan por la degeneración de las neuronas motoras de la médula espinal y del tronco encefálico, lo que resulta en hipotonía y debilidad muscular. El objetivo es la descripción de 5 casos de pacientes con diagnóstico genético de AME tipo I, todos los pacientes con número de copias para SMN2: 2 copias y Gen SMN 1 con deleción Homocigótica.
Métodos: Se describen las manifestaciones clínicas y los resultados genéticos de 5 pacientes con diagnóstico de AME tipo I. Se describen además las posibilidades de tratamiento y abordaje multidisciplinario en los pacientes.
Resultados: Se incluyeron cinco pacientes con diagnóstico clínico y genético de Atrofia Muscular Espinal tipo I, dos eran del sexo masculino, tres del sexo femenino, en un rango de edad entre los 11 meses y los 22 meses. La proporción hombre: mujer fue de 2:3. El antecedente de familiar de primera línea con atrofia muscular espinal se registró en 1 de 5 pacientes. La ausencia de reflejos de estiramiento muscular (REMS) en extremidades superiores e inferiores fue un signo que compartía el 100% de los pacientes.
Conclusiones: La mayor atención al diagnóstico temprano y al manejo de la atrofia muscular espinal ha estimulado el desarrollo de guías y estándares de atención que han afectado la supervivencia y la historia natural de la enfermedad. No existe un tratamiento médico eficaz para la atrofia muscular espinal. Sin embargo, desde el descubrimiento del gen causante de la enfermedad, se ha logrado un gran progreso en la comprensión de la patogénesis molecular, lo que ha llevado al desarrollo de opciones de tratamiento.

“One of Koestler’s Best”
Authors: Vernyik Zénó 
Published: July 2022

ABSTRACT
This article analyzes the immediate critical reception of Arthur Koestler’s Arrival and Departure. The third novel published in his lifetime, it was the first Koestler wrote in English. Although a commercial success, his biographies disagree on the novel’s critical reception: some claim it was a success, others talk of a reserved or hostile reception. As a part of an ongoing larger project, the present article shows, based on the analysis of sixty reviews published between 1943 and 1946, that the novel had an unqualified critical success. Further, through comparing this reception to that of Thieves in the Night, it pinpoints that Arrival and Departure is both comparatively less obscure than Thieves in the Night, and, unlike in the case of the other novel, the contemporary status of Arrival and Departure is not the result of an uncritical rehashing of old critical remarks. This quantitatively informed treatment is then juxtaposed to a discussion of three specific claims of the early reviews (flat characters, weak plot, and a polemical structure) in terms of their connection to the book’s genre. Finally, the paper emphasizes that regardless of the iconic status of Darkness at Noon, Arthur Koestler clearly should not be considered as a one-book wonder.
