Non-thermal electrons in an eruptive solar event: Magnetic structure, confinement, and escape into the heliosphere
Authors: Klein Karl-Ludwig , Salas Matamoros Carolina , Hamini Abdallah , Kollhoff Alexander 
Published: August 2024

Context. Filament eruptions and coronal mass ejections (CMEs) reveal large-scale instabilities of magnetic structures in the solar corona. Some of them are accompanied by radio emission, which at decimetric and longer wavelengths is a signature of electron acceleration that may be different from the acceleration in impulsive flares. The radio emission is part of the broadband continua at decimetre and metre wavelengths called type IV bursts.
Aims. In this article we investigate a particularly well-observed combination of a filament eruption seen in Hα and at extreme ultraviolet (EUV) wavelengths and a moving type IV burst on 2021 August 24. The aim is to shed light on the relationship between the large-scale erupting magnetic structure and the acceleration and transport of non-thermal electrons.
Methods. We used imaging observations of a moving radio source and associated burst groups with the refurbished Nançay Radioheliograph and whole-Sun radio spectrography from different ground-based and space-borne instruments, in combination with X-ray, radio, and in situ electron observations at tens of keV from Solar Orbiter and EUV imaging by SDO/AIA. The radio sources are located with respect to the erupting magnetic structure traced by the filament (EUV 30.4 nm), and the timing of the electrons detected in situ is compared with the timing of the different radio emissions.
Results. We find that the moving radio source is located at the top of the erupting magnetic structure outlined by the filament, which we interpret as a magnetic flux rope. The flux rope erupts in a strongly non-radial direction, guided by the overlying magnetic field of a coronal hole. The electrons detected at Solar Orbiter are found to be released mainly in two episodes, 10–40 minutes after the impulsive phase. The releases coincide with two groups of radio bursts, which originate respectively on the flank and near the top of the erupting flux rope.
Conclusions. The observation allows an unusually clear association between a moving type IV radio burst, an erupting magnetic flux rope as core structure of a CME, and particle releases into the heliosphere. Non-thermal electrons are confined in the flux rope. Electrons escape to the heliosphere mainly in two distinct episodes, which we relate to magnetic reconnection between the flux rope and ambient open field lines.

AbstractRetroperitoneal liposarcomas are rare, and their variants, atypical spindle cell lipomatous tumor (ASCLT), are rarer. Though ASCLTs are benign, they have high recurrence despite complete surgical excision. We present a rare case of a 22-year-old male presented with insidious-onset, and gradually progressive swelling over left inguinofemoral, and iliac fossa region. Also, the patients had a history of weight loss, pricking-type pain radiating to left lower limb, and breathlessness on exertion. Contrast-enhanced computed tomography (CECT) abdomen revealed a large well-defined heterogeneously enhancing soft mass located in pelvis, and involving left-sided iliopsoas muscle suggestive of retroperitoneal soft tissue sarcoma and CECT thorax showed metastasis. The CT-guided core biopsy led to the definitive diagnosis of low-grade ASCLT. Subsequently, the patient was initiated on concurrent neoadjuvant chemoradiotherapy followed by complete surgical excision. The findings in this report make it critical to enhance our understanding of this rare tumor, with surgery being the best treatment option.

Abstract
Background The origin of autoantibodies in patients with antiphospholipid syndrome (APS) is unknown. The gut microbiome contributes to autoimmunity and contains peptide homologues to the main APS autoantigen, which affect disease activity in animal models. Alteration of the gut microbiota with vancomycin diminishes disease activity in mice but no data on the effect of gut microbiota alteration in APS patients are available to date.
Objective To evaluate whether the gut microbiome affects disease activity in human APS.
Methods This was a pre–post design intervention study in APS patients with stable disease and no gastrointestinal comorbidity. Subjects received oral vancomycin, 500 mg four times daily for 7 days, previously shown to alter gut microbiota composition without systemic effects. Disease activity was assessed at four time points by measuring a panel of clinical phenotype-related biomarkers: antiphospholipid antibodies (APLAs), complement and inflammation markers, and hemostatic parameters. The primary outcome was the composite of the biomarker panel determined by multilevel principal component analysis.
Results A total of 15 subjects completed the study. The primary outcome, the first principal component of the biomarker panel data, was significantly different after 7 days of vancomycin treatment (p = 0.03), but not at day 42. APLA titers were unaffected. Unexpectedly, 4 out of 15 patients were negative for APLAs at baseline. In a post-hoc analysis, there was a prolonged effect for subjects with positive antibodies at baseline (p = 0.03). In subjects with negative APLAs at baseline, the intervention showed no effect.
Conclusion The intestinal microbiome affects the biochemical disease activity in APS patients. The mechanism is yet unknown but appears to be APS-specific.
Clinical Profile of Febrile Neutropenia in Children with Malignancies in a Tertiary Care Hospital: A Prospective Observational Study
Authors: Mariam Ayesha , Hegde Niranjan Gurunath , Srinivasan Arathi , Thangadorai Ravikumar 
Published: August 2024

Abstract
Introduction Febrile neutropenia is a dreadful complication associated with malignancies. Knowledge of locally prevalent pathogens and their resistance pattern is of paramount importance in guiding antimicrobial therapy.
Objectives The aim of the study was to identify the common infectious agent, antibiotic susceptibility of culture positive patients, and outcome
Materials and Methods We conducted a single-center prospective observational study. Forty-three children with febrile neutropenia episodes admitted in KKCTH, Chennai, were included in the study. The duration of the study was 1 year. Relevant patient and disease specific details were obtained, results were analyzed, and conclusions were drawn.
Results There were 90 episodes of febrile neutropenia. Overall culture positivity was identified in 37 cases (41.11%). Bacteremia (23.3%) was the most common cause of microbiologically documented infection. Gram-positive organisms (60%) were more commonly documented. Among the gram-positive organisms, coagulase-negative Staphylococcus aureus was the predominant isolate followed by Streptococcus. Central line–associated bloodstream infections were documented in 13.33%. Chemo-port removal was done in four children. Three had invasive fungal disease. The majority of the gram-negative isolates were resistant strains. Morbidity was significantly more in gram-negative infections. Overall outcome was good though three children succumbed to sepsis.
Conclusion A vigilant management of illness is essential. Chemo-port carries risk of severe infection. Protocol-based management of catheter-related bloodstream infection (CRBSI) can limit the number of chemo-port removal. Though gram-positive organisms are in the rise, gram-negative organisms are still responsible for significant morbidity. Early initiation of broad-spectrum empirical antibiotics with optimal gram-positive coverage is crucial. Children with suspected fungal infections should be aggressively evaluated and treated. An organized approach is the key in successful management.
A Rare and Intriguing Case of Papillary Thyroid Carcinoma with Tumor Thrombus Extending into the Right Ventricle: Documentation with 131I-NaI-SPECT/CT, MRI, and 18F-FDG-PET/CT

Published: August 2024

AbstractA unique case of papillary carcinoma of the thyroid with an extensive tumor thrombus extending into the right ventricle is presented. The patient was a known case of solid variant of papillary carcinoma of thyroid, post three cycles of radioiodine therapy, had reported for a diagnostic 131I-NaI scintigraphy as a part of the workup for planning the next 131I therapy. Clinically, the patient was asymptomatic. 131I-NaI scintigraphy showed an arcuate pattern concentration of tracer in the upper mediastinum, which descended up to the lower mediastinum. A 131I-NaI single photon emission computed tomography/computed tomography (SPECT/CT) showed a tracer avid tumor with an extensive tumor thrombus extending from the left brachiocephalic vein to the right ventricle. 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG-PET/CT) and magnetic resonance imaging (MRI) demonstrated similar findings. The patient was decided to be managed with tyrosine kinase inhibitors as surgical intervention was not deemed possible due to the involvement of major vessels and the high risk of bleeding.

Abstract
Objective The aim of this study is to create clinical normative data for ulnar length in the pediatric population and to demonstrate the usefulness of such data.
Materials and Methods A nationally representative sample of healthy children aged 1 day to 18 years from five centers across India was collected. The percutaneous length of the ulna was measured by using a certified calibrated measuring tape across all centers. Other variables such as geographical domicile, dominance of the hand, age, body mass index (BMI), and sex of the child were also recorded.
Results In total, 1,300 children (883 males and 417 females) with age ranging from 1 day to 18 years were included in the study. Gradual lengthening of the ulna was seen in both male and female children with increasing age without a significant difference; however, at 8, 9, and 14 years, there was significant lengthening of the ulna in males compared with females although the difference was statistically insignificant at 17 years. Apropos BMI at 16 years of age, a longer ulna was observed in obese children. Later on, at 18 years, the difference in ulnar length was insignificant. South Indian children had a significantly longer ulna up to the age of 11 years, but after the age of 11 years there was no difference in ulnar length in all zones. The length of the ulna was not affected by hand dominance. There was good inter-observer agreement and reliability between different centres. Age, zone, and gender, had statistically significant effect on the length of ulna but BMI and hand dominance was not significant.
Conclusion This multicentric study provides normative data on the percutaneous length of the ulna in the Indian pediatric population. Gradual lengthening of the ulna was seen in all children with increasing age. The length of the ulna was significantly more in male, obese, and in South Indian children. However, except for age, other factors become insignificant at maturity.

Framing interactivity in complex communication of debate talk show
Authors: Vasilyeva Alena L. 
Published: August 2024

Abstract
The present study explores how disagreement space is managed in a multiparty argumentative activity of debate talk show that focuses on the political situation in Belarus. The communicative activity under study is viewed as a type of difficult conversation that takes place between two groups that differ in their ideologies (Ellis 2020). In particular, drawing on the polylogical framework of argumentation (Lewiński and Aakhus 2023) and communication design approach (Aakhus 2007), the study investigates the communicative practice of framing that the moderators and the debaters use to shape disagreement space. The analysis shows that the activity is polylogical not just in a sense of positions, participants, and places (Lewiński and Aakhus 2023), but also in how argumentative activity is framed, which has consequences for how the interactivity is constructed and how disagreement space is managed in the course of interaction. It also shows how the interweaving of negative and positive features of communication add to the complexity of difficult interaction.
Landscaping gender, sexuality, and hope in the 2022 Philippine presidential elections
Authors: Go Christian 
Published: August 2024

Abstract
This paper investigates the Linguistic Landscape (LL) of Leni Robredo’s 2022 presidential campaign rallies in the
Philippines and explores the role of gender and sexuality in constructing prefigurative spaces within the offline-online nexus.
Through artifacts used during the campaign, the paper examines how Robredo supporters utilize semiotic resources and intertextual
references from popular and meme culture as well as LGBTQ+ media to adopt stances vis-à-vis gender and sexuality. The paper
suggests that the aggregation of these stances elicit affects that facilitate a prefigurative genderscape where participants enact
an ethos of hope. While these practices cannot completely transcend entrenched forms of power (e.g., macho populism and dynastic
democracy), they materialize a potential future characterized by a people-driven movement. The paper proposes a future direction
for LL studies: engaging prefigurative politics in the examination of the emergent spaces that respond to increasing precarity and
sociopolitical upheavals.
“Determined to prove a villain”
Authors: Spišiaková Eva 
Published: August 2024

Abstract
Shakespeare’s play Richard III represents a fascinating phenomenon from the perspective of critical disability studies. On the one hand, his portrayal stands at the root of the much-criticised link between evil intentions and a physical deformity; on the other, the play allows Richard to reclaim some of the agency of his own corporeality, as he uses his body to gain his political goals. Translations of this play inevitably mirror contemporary views of non-normative bodies, and the two Slovak versions of the play marking the immediate aftermath of World War II and the last years of the communist rule in former Czechoslovakia provide an ideal ground for observing these shifts against the backdrop of significant sociopolitical changes. This article explores how the subtle nuances in individual translated versions reshape Richard’s image, and ultimately highlights the changing historical narratives of disability translated for different generations of Slovak readers and theatregoers.
Translation as retelling
Authors: Wan Tenglong 
Published: August 2024

Abstract
Taking the perspective that translation is a form of (re)narration that participates in (re)constructing social
reality (Baker 2018), this article examines how translation is used as a rigorous means
for mediating meaning, narrativity and cultural representation. Focusing on a case study of Amores do Céu e da Terra:
Contos de Macau (2014), a Portuguese version of the original Chinese prose essay collection Youqing
Tiandi (1991), this article examines the Portuguese version as “reconto” (retelling) to see how the public
(collective) narratives of Macao are reframed by the translators in the target language and culture. The analysis reveals that the
original narratives are reconstructed by the Portuguese translators through their agency at the contextual, textual, intertextual
and paratextual levels. Such reframing has resulted in a new version that reconstructs the public narratives and cultural image of
Macao for Portuguese readers.
Hybrid-order Weyl semimetal and its acoustic realizations
Authors: Wei Qiang , He Ai-Lei , Yan Mou , He Hailong , Jia Suotang 
Published: August 2024

Abstract
Hybrid-order topological insulators combine first- and higher-order topological properties and host topological boundary states with codimension one and more than one in different bandgaps. A Weyl semimetal (WSM) can possess two types of Weyl points: one class of Weyl points terminates the Fermi arc surface states, while another class of Weyl points not only launch Fermi arc surface states but also hinge arc states, exhibiting the hybrid-order topology. Here, we propose a hybrid-order WSM by stacking two-dimensional rhomboid lattices based on chiral nearest-neighbor and double-helix next-nearest interlayer couplings. The first type of Weyl point that only truncates the Fermi arc surface states exists at the crossing of any two-fold degeneracy of two adjacent bands, and the second type of Weyl point that connects the hinge arc states only appears at the crossing of the two middle bands. Our findings enrich the classification of topological semimetals in condensed matter physics.
A finite volume approach to dosimetric calculations in diffusing alpha-emitters radiation therapy

Published: August 2024

Abstract

Objective. In diffusing alpha-emitters radiation therapy (‘Alpha DaRT’), the diffusion-leakage (DL) model is used to determine the spatial distributions of the emitters and the corresponding alpha dose, critical for a successful treatment. This work first introduces a finite volume (FV) approach to develop numerical schemes to simulate the DL model in one, two and three dimensions then presents how variations over realistic ranges of the DL model parameters related to desorption, diffusion and leakage processes affect the alpha dose distribution and the position of the clinically significant alpha particle

This work also presents the effects of three modeling approximations: two source geometry approximations (solid cylinder instead of hollow, pixelized cross section instead of circular), and one dosimetric approximation (single-source dose superposition instead of multiple-sources direct dose calculation). Approach. The introduced FV approach was used to obtain spatial distributions of the emitters, from which the corresponding alpha dose distributions were calculated under the assumption of a local deposition of the alpha particles’ energies. Variation ranges of the DL model parameters were based on previously published data. For each modeling approximation studied, the error and relative error on the alpha dose distribution were calculated and the displacement of the

Abstract
Transcranial magnetic stimulation (TMS) is a non-invasive method for stimulating the cortex. Concurrent functional magnetic resonance imaging can show changes in TMS-induced activity in the whole brain, with the potential to inform brain function research and to guide the development of TMS therapy. However, the interaction of the strong current pulses in the TMS coil in the static main magnetic field of the MRI produces high Lorentz forces, which may damage the coil enclosure and compromise the patient’s safety. We studied the time-dependent mechanical behavior and durability of two multi-locus TMS (mTMS) coil arrays inside a high-field MRI bore with finite element modeling. In addition, coil arrays were built and tested based on the simulation results. We found that the current pulses produce shock waves and time-dependent stress distribution in the coil plates. The intensity and location of the maximum stress depend on the current waveform, the coil combination, and the transducer orientation relative to the MRI magnetic field. We found that 30% glass-fiber-filled polyamide is the most durable material out of the six options studied. In addition, novel insights for more durable TMS coil designs were obtained. Our study contributes to a comprehensive understanding of the underlying mechanisms responsible for the structural failure of mTMS coil arrays during stimulation within high static magnetic fields. This knowledge is essential for developing mechanically stable and safe mTMS-MRI transducers.

Abstract
This article represents a single-layered two-port MIMO antenna loaded into a compact plane-patterned metamaterial (MTM) structure for a 5G communication system. The antenna operates at three bands to investigate metamaterial properties in addition to diversity parameters, an arrangement of a series of arrays suggested a 2-port design antenna and a circular-shaped split ring resonator unit cell was developed. The design of a single port antenna utilizes 1 × 3 MTM unit cells for each component. This antenna operates within a frequency range ranging from 1 GHz to 15 GHz. Additionally, the suggested MIMO antenna offers a dominant isolation of –55dB. The measurement’s results show that, with an entire antenna size of 112 mm × 26.5 mm and a 3.33 GHz bandwidth, the MIMO antenna is achieved with good efficiency and CCL < 0.35, considerable DG > 9.97dB, ECC < 0.18, and TARC <–9.97. The presented design is suitable for medical imaging, RFID, Bluetooth, Wi-Fi, WiMAX, IOT, satellite communication systems, and the 5G and sub-6 GHz spectrum.
