Published: March 2023

Abstract
We studied a blowout jet that occurred at the west limb of the Sun on 2014 August 29 using high-resolution imaging/spectroscopic observations provided by the Solar Dynamics Observatory/Atmospheric Imaging Assembly and the Interface Region Imaging Spectrograph. An inverse γ-shaped flux rope appeared before the jet–morphological indication of the onset of kink instability. The twisted field lines of the kink-unstable flux rope reconnected at its bright knot and launched the blowout jet at ≈06:30:43 UT with an average speed of 234 km s−1. Just after the launch, the northern leg of the flux rope erupted completely. The time–distance diagrams show multiple spikes or bright dots, which is the result of periodic fluctuations, i.e., quasi-periodic fluctuations (QPPs). The wavelet analysis confirms that QPPs have a dominant period of ≈3 minutes. IRIS spectra (Si iv, C ii, and Mg ii) may also indicate the occurrence of magnetic reconnection through the existence of broad and complex profiles and bidirectional flows in the jet. Further, we found that line broadening is periodic with a period of ≈3 minutes, and plasma upflow always occurs when the line width is high, i.e., multiple reconnection may produce periodic line broadening. The emission measure (EM) curves also show the same period of ≈3 minutes in different temperature bins. The images and EM show that this jet spire is mainly cool (chromospheric/transition region) rather than hot (coronal) material. Further, line broadening, intensity, and EM curves have a period of ≈3 minutes, which strongly supports the fact that multiple magnetic reconnection triggers QPPs in the blowout jet.

Abstract
Magnetohydrodynamic (MHD) and photoevaporative winds are thought to play an important role in the evolution and dispersal of planet-forming disks. Here, we analyze high-resolution (Δv ∼ 7 km s−1) optical spectra from a sample of 115 T Tauri stars in the ∼5–10 Myr Upper Sco association and focus on the [O i] λ6300 and Hα lines to trace disk winds and accretion, respectively. Our sample covers a large range of spectral types and we divide it into warm (G0-M3) and cool (later than M3) to facilitate comparison with younger regions. We detect the [O i] λ6300 line in 45 out of 87 Upper Sco sources with protoplanetary disks and 32 out of 45 are accreting based on Hα profiles and equivalent widths. All [O i] λ6300 Upper Sco profiles have low-velocity (centroid < −30 km s−1; low-velocity component (LVC)) emission and most (36/45) can be fit by a single Gaussian (SC). The single-component (SC) distribution of centroid velocities and FWHMs is consistent with MHD disk winds. We also find that the Upper Sco sample follows the same accretion luminosity−LVC [O i] λ6300 relation and the same anticorrelation between SC FWHM and Wide-field Infrared Survey Explorer W3-W4 spectral indices as the younger samples. These results indicate that accretion and disk winds coevolve and that, as inner disks clear out, wind emission arises further away from the star. Finally, our large spectral range coverage reveals that cool stars have larger FWHMs normalized by stellar mass than warm stars indicating that [O i] λ6300 emission arises closer in toward lower-mass/lower luminosity stars.

Published: March 2023

Abstract
We have combined resolved stellar photometry from Hubble Space Telescope (HST), Spitzer, and Gaia to identify red supergiant (RSG) candidates in NGC 6946, based on their colors, proper motions, visual morphologies, and spectral energy distributions. We start with a large sample of 17,865 RSG candidates based solely on HST near-infrared photometry. We then chose a small sample of 385 of these candidates with Spitzer matches for a more detailed study. Using evolutionary models and isochrones, we isolate a space where RSGs would be found in our photometry catalogs. We then visually inspect each candidate and compare them to Gaia catalogs to identify and remove foreground stars. As a result, we classify 95 potential RSGs, with 40 of these being in our highest-quality sample. We fit the photometry of the populations of stars in the regions surrounding the RSGs to infer their ages. Placing our best candidate RSG stars into three age bins between 1 and 30 Myr, we find 27.5% of the candidates falling between 1–10 Myr, 37.5% between 10–20 Myr, and 35% between 20–30 Myr. A comparison of our results to the models of massive star evolution shows some agreement between model luminosities and the luminosities of our candidates for each age. Three of our candidates appear significantly more consistent with binary models than single-star evolution models.

Abstract
Astro-rivelatore Gamma a Immagini Leggero (AGILE) is a space mission launched in 2007 to study X-ray and gamma-ray astronomy. The AGILE team developed real-time analysis pipelines to detect transient phenomena such as gamma-ray bursts (GRBs) and react to external science alerts received by other facilities. The AGILE anticoincidence system (ACS) comprises five panels surrounding the AGILE detectors to reject background-charged particles. It can also detect hard X-ray photons in the energy range 50–200 keV. The ACS data acquisition produces a time series for each panel. The time series are merged into a single multivariate time series (MTS). We present a new deep-learning model for the detection of GRBs in the ACS data using an anomaly detection technique. The model is implemented with a convolutional neural network autoencoder architecture trained in an unsupervised manner, using a data set of MTSs randomly extracted from the AGILE ACS data. The reconstruction error of the autoencoder is used as the anomaly score to classify the MTS. We calculated the associated p-value distribution, using more than 107 background-only MTSs, to define the statistical significance of the detections. We evaluate the trained model with a list of GRBs reported by the GRBWeb catalog. The results confirm the model’s capabilities to detect GRBs in the ACS data. We will implement this method in the AGILE real-time analysis pipeline.
A Study of Preflare Solar Coronal Magnetic Fields: Magnetic Energy and Helicity

Published: March 2023

Abstract
Solar flares fall into two types, with eruptive ones associated with coronal mass ejection (CME) and confined ones without CME. To explore whether there are preflare conditions in terms of magnetic energy and helicity that can effectively determine the types of flares, here we analyzed a suite of related parameters of the reconstructed preflare coronal magnetic field of major solar flares, either eruptive or confined, from 2011 to 2017 near the solar disk center. The investigated parameters include extensive-type quantities such as the total magnetic energy E

We have the following key findings: (1) None of the extensive parameters can effectively distinguish the eruptive and confined potential of the preflare coronal fields, though the confined events have averagely larger values.

Cutting Edge: Influenza-Induced CD11alo Airway CD103+ Tissue Resident Memory T Cells Exhibit Compromised IFN-γ Production after In Vivo TCR Stimulation
Authors: van de Wall Stephanie , Crooks Sequoia , Varga Steven M , Badovinac Vladimir P , Harty John T 
Published: March 2023

Abstract
Although tissue resident memory T cells (TRM) in the lung confer robust protection against secondary influenza infection, their in vivo production of IFN-γ is unknown. In this study, using a mouse model, we evaluated production of IFN-γ by influenza-induced TRM (defined as CD103+) that localize to the airways or lung parenchyma. Airway TRM consist of both CD11ahi and CD11alo populations, with low CD11a expression signifying prolonged airway residence. In vitro, high-dose peptide stimulation evoked IFN-γ from most CD11ahi airway and parenchymal TRM, whereas most CD11alo airway TRM did not produce IFN-γ. In vivo production of IFN-γ was clearly detectable in CD11ahi airway and parenchymal TRM but essentially absent in CD11alo airway TRM, irrespective of airway-instilled peptide concentration or influenza reinfection. The majority of IFN-γ–producing airway TRM in vivo were CD11ahi, suggesting recent airway entry. These results question the contribution of long-term CD11alo airway TRM to influenza immunity and reinforce the importance of defining TRM tissue compartment–specific contributions to protective immunity.
Lower Extremity Energy Dissipation and Generation During Jump Landing and Cutting in Patients With Chronic Ankle Instability
Authors: Han Seunguk , Lee Hyunwook , Oh Minsub , Hopkins J. Ty 
Published: March 2023

Context
Participants with chronic ankle instability (CAI) frequently display altered movement patterns during functional movements. However, it remains unclear how these altered joint kinematics during jump landing negatively affect ankle joint health in the CAI population. Calculating joint energetics may offer an important method to estimate the magnitude of lower extremity joint loading during functional movements in participants with CAI.

Objective
To determine differences in energy dissipation and generation by the lower extremity during maximal jump landing and cutting among groups with CAI, copers, and controls.

Design
Cross-sectional study.

Setting
Laboratory.

Patients or Other Participants
Forty-four participants with CAI, 44 copers, and 44 controls.

Main Outcome Measures(s)
Kinematics and kinetics of the lower extremity and ground reaction force data were collected during a maximal jump-landing and cutting task. The product of angular velocity in the sagittal plane and joint moment data represented joint power. Energy dissipation and generation by the ankle, knee, and hip joints were calculated by integrating regions of the joint power curve.

Results
Participants with CAI displayed reduced ankle energy dissipation (35.9% ± 10.1%) and generation (31.6% ± 12.8%; P &lt; .01) compared with copers (dissipation = 43.6% ± 11.1%; generation = 40.4% ± 12.0%) and controls (dissipation = 41.3% ± 11.1%; generation = 39.6% ± 12.0%) during maximal jump landing and cutting. Participants with CAI also displayed greater energy dissipation at the knee (45.1% ± 9.1%) than copers (39.7% ± 9.5%) during the loading phase and greater energy generation at the hip than controls (36.6% ± 16.8% versus 28.3% ± 12.8%) during the cutting phase. However, copers displayed no differences in joint energetics compared with controls.

Conclusions
Participants with CAI displayed differences in both energy dissipation and generation by the lower extremity during maximal jump landing and cutting. However, copers did not show altered joint energetics, which may represent a coping mechanism to avoid further injuries.
Utility of the Counseling Center Assessment of Psychological Symptoms Screen in a Collegiate Athlete Population
Authors: Higgins Kate , Woods Brett , Haskell Brett , Bullock Mariah , Rogers Rachel , Izuegbunam Nedu 
Published: March 2023

Context
Mental health screening as a part of collegiate athletic preparticipation evaluations is becoming increasingly common, but effective and efficient screening depends on a screening tool that can accurately identify mental health symptoms and the need for mental health intervention.

Design
Case-control study.

Setting
Archival clinical records review.

Patients or Other Participants
Two cohorts of incoming National Collegiate Athletics Association Division I collegiate athletes (N = 353).

Main Outcome Measure(s)
Athletes completed the Counseling Center Assessment of Psychological Symptoms (CCAPS) Screen as a part of their preparticipation evaluation. These data were then matched with basic demographic data and mental health treatment history from clinical records, and the utility of the CCAPS Screen in determining a future or ongoing need for mental health services was analyzed.

Results
Score differences for each of the 8 CCAPS Screen scales (Depression, Generalized Anxiety, Social Anxiety, Academic Distress, Eating Concerns, Frustration, Family Distress, and Alcohol Use) were found based on several demographic variables. Logistic regression analysis demonstrated that female sex, team sport participation, and the Generalized Anxiety scale score predicted future participation in mental health treatment. Decision tree testing of the CCAPS scales showed low utility in classifying those who received mental health treatment versus those who did not.

Conclusions
The CCAPS Screen did not appear to differentiate well between those who eventually received mental health services and those who did not. This should not be taken to mean that mental health screening is not useful but rather that a 1-time, state-based screening is not sufficient for athletes who experience intermittent but recurring stressors in a dynamic environment. A proposed model for improving the current standard of practice for mental health screening is provided as a focus of future research.

Published: March 2023

ABSTRACT.
Cranial tuberculosis is a relatively infrequent inflammatory reaction caused by tuberculous bacilli invading the skull. Most cases of cranial tuberculosis are secondary to tuberculosis foci in other parts of the body; primary cranial tuberculosis is extremely rare. Herein, we report a case of primary cranial tuberculosis. A 50-year-old man presented to our hospital with a mass in the right frontotemporal region. Chest computed tomography and abdominal ultrasonography findings were normal. Magnetic resonance imaging of the brain revealed a mass in the right frontotemporal skull and scalp with cystic changes, adjacent bone destruction, and meningeal invasion. The patient underwent surgery and was diagnosed with primary cranial tuberculosis; he was treated with antitubercular therapy postoperatively. No recurrent masses or abscesses were observed during the follow-up.

Published: March 2023

ABSTRACT.
This study highlights the development of two lateral flow recombinase polymerase amplification assays for the diagnosis of human malaria. The lateral flow cassettes contained test lines that captured biotin-, 6-carboxyfluorescein, digoxigenin-, cyanine 5-, and dinitrophenyl-labeled amplicons. The overall process can be completed in 30 minutes. Recombinase polymerase amplification coupled with lateral flow had a detection limit of 1 copy/µL for Plasmodium knowlesi, Plasmodium vivax, and Plasmodium falciparum. No cross-reactivity was observed among nonhuman malaria parasites such as Plasmodium coatneyi, Plasmodium cynomolgi, Plasmodium brasilanium, Plasmodium inui, Plasmodium fragile, Toxoplasma gondii, Sarcocystis spp., Brugia spp., and 20 healthy donors. It is rapid, highly sensitive, robust, and easy to use. The result can be read without the need for special equipment and thus has the potential to serve as an effective alternative to polymerase chain reaction methods for the diagnosis of malaria.

A fenntarthatóság eszményének politikai, a fenntarthatósági számvitelnek pedig tudományos térnyerése közel 40 évre tekint vissza. Amíg kezdetben a fenntartható működés (vállalati, állami és globális szinten) lehetőséget jelentett, napjainkban az egyes nemzetállamoknak és nemzetek közösségének kötelező jogi aktusai folyamatosan gyarapodnak, kényszerítve a polgárokat és a vállalatokat ebben az irányban lépéseket tenni. Jelen cikk egy lépést tesz hátra és az alapvető összefüggésekben rejlő ellentmondásokat, problémákat és korlátokat szeretné érzékeltetni ezen a területen. A tanulmányban a téma általános bemutatása után a fókusz a társadalmi fenntarthatóság aspektusára, azon belül pedig az esélyegyenlőség kérdésére helyeződik.
