Transverse MHD Waves as Signatures of Braiding-induced Magnetic Reconnection in Coronal Loops
Authors: Sukarmadji A. Ramada C. , Antolin Patrick 
Published: January 2024

Abstract
A major coronal heating theory based on magnetic reconnection relies on the existence of braided magnetic field structures in the corona. In this small-angle reconnection scenario, numerical simulations indicate that the reconnected magnetic field lines are driven sideways by magnetic tension and can overshoot from their new rest position, thereby leading to low-amplitude transverse MHD waves. This provides an efficient mechanism for transverse MHD wave generation, and the direct causality also constitutes substantial evidence of reconnection from braiding. However, this wave-generation mechanism has never been directly observed. Recently, the telltale signature of small-angle reconnection in a sheared coronal structure has been identified through nanojets, which are small, short-lived, and fast jetlike bursts in the nanoflare range transverse to the guide field. We present for the first time Interface Region Imaging Spectrograph and Solar Dynamics Observatory observations of transverse MHD waves in a coronal loop that directly result from braiding-induced reconnection. The reconnection is identified by the presence of nanojets at the loop apex that release nanoflare-range energy. We find that the oscillations have an energy flux on the order of 106–108 erg cm−2 s−1, which is within the budget to power active region loops. The estimated kinetic and thermal energy from the nanojets is also sufficient to power the transverse waves and sustain the observed heating at the loop apex. This discovery provides major support to (a) existing theories that transverse MHD waves can be a signature of reconnection, (b) the existence of braiding in coronal structures, and (c) the coronal reconnection scenario identified by nanojets.
Lunar Mare Lava Flow Dynamics and Emplacement: Predictions of Non-Newtonian Flow Dynamics, Syn- and Post-emplacement Cooling and Volatile Release Patterns, and Vertical and Lateral Flow Structure Development
Authors: Wilson Lionel , Head James W. 
Published: January 2024

Abstract
We apply basic principles of magma ascent from deep source regions and its eruption into a low-gravity vacuum environment to develop a theoretical treatment of the fluid dynamics and thermodynamics of mare basalt lava flow emplacement and evolution on the Moon. The vacuum conditions influenced the release of volatiles in magma passing through lava fountains, thus controlling the syn- and post-emplacement vesicularity of the resulting deposits. To explain observed lengths and volumes of Mare Imbrium–type flows, high (106–105 m3 s−1) initial magma eruption rates were needed. Combined with low lunar magma viscosity, these caused flows to be initially turbulent. Resulting high radiative heat loss and consequent high crystallization rates caused rapid non-Newtonian rheological evolution and suppression of turbulence at tens of kilometers from vents. Slower cooling rates in the subsequent laminar parts of flows imply distinctive crystal growth rate histories. In a four-phase sequence, (i) initial transient dike-tip gas release followed by (ii) Hawaiian fire fountain activity with efficient volatile loss (iii) transitioned to (iv) Strombolian explosions in a lava lake. Late-stage lava now able to retain volatiles intruded and inflated existing flow deposits after flow front advance ceased. Volatiles forced out of solution by second boiling as lava cooled caused additional inflation. Low gravity and lack of atmospheric pressure commonly produced very vesicular lava. Escape of such lava through cracks in flow crusts is a possible source of ring-moat dome structures; collapse of such lava may explain irregular mare patches.

Abstract
We have monitored the Didymos–Dimorphos binary system in imaging polarimetric mode before and after the impact from the Double Asteroid Redirection Test mission. A previous spectropolarimetric study showed that the impact caused a dramatic drop in polarization. Our longer-term monitoring shows that the polarization of the post-impact system remains lower than the pre-impact system even months after the impact, suggesting that some fresh ejecta material remains in the system at the time of our observations, either in orbit or settled on the surface. The slope of the post-impact polarimetric curve is shallower than that of the pre-impact system, implying an increase in albedo of the system. This suggests that the ejected material is composed of smaller and possibly brighter particles than those present on the pre-impact surface of the asteroid. Our polarimetric maps show that the dust cloud ejected immediately after the impact polarizes light in a spatially uniform manner (and at a lower level than pre-impact). Later maps exhibit a gradient in polarization between the photocentre (which probes the asteroid surface) and the surrounding cloud and tail. The polarization occasionally shows some small-scale variations, the source of which is not yet clear. The polarimetric phase curve of Didymos–Dimorphos resembles that of the S-type asteroid class.
Towards a set of metrics for hybrid (quantum/classical) systems maintainability

Published: January 2024

Given the rapid evolution that has taken place in recent years in the software industry, and along with it the emergence of quantum software, there is a need to design an environment for measuring quality metrics for hybrid, classic-quantum software.&nbsp;
In order to measure and evaluate the quality of classic software, there are models and standards, among which ISO/IEC 25000 stands out, which proposes a set of quality characteristics such as maintainability. However, there is currently no consensus for the measurement and evaluation of quantum software quality.&nbsp;
In this paper we propose a series of adaptations to &ldquo;classic&rdquo; metrics, as well as a set of new measurements for hybrid maintainability. Finally, a first prototype of a measurement tool developed as a SonarQube plugin, capable of measuring these metrics in quantum developments, is also presented.&nbsp;

Authors: Anvari Roya , Janjaria Mariam , Shirvani Ali 
Published: January 2024

Purpose: This study aims to explain the role of line managers in human resource activities. It is a case study in West Midlands.Design/methodology/approach: The trend of line managers (LMs) involvement in human resource (HR) activities has been on-going for a while. There has been a lot of intellectual debate and controversy on the issue. Also, organisations have faced lots of challenges due to this same issue. This study aims to discover how to cope with this problem by utilizing human resources activities. This research adopted a qualitative single case study approach on a University in West Midlands, UK. In the first instance, 35 respondents consisting of line managers and HR practitioners across the Business School were invited to participate in this research. Within the context of LMs, purposive sampling was used.Findings: The findings show that Line Managers that enhances abilities are significantly associated to HR activities. Line Managers that enhance motivation and involvement are significantly assocaited to HR activities. And the results showed that HR respondent 1 to 5 said LMs play an important role and are needed to carry out HR activities.Originality/value: The analysis of the case, highlights the benefits of the novel idea of line managers and human resource practitioners and contributes to the need for greater clarity and knowledge of the barriers in the involvement of LMs in HR activities. Social implications: This study has shown LMs and HR practitioners have their different reserves about working together but the issue presently is, none of them is dispensable so they have to work together. It is necessary for HR practitioners to consult LMs when formulating policies and procedures to ensure balance between business needs and standard policies, and procedures.
Est-il préférable d’apprendre les langues minoritaires à l’âge adulte ?L’exemple du breton
Authors: Gildas Grimault 
Published: January 2024

La politique éducative est l’un des outils privilégiés des politiques de revitalisation des langues minoritaires. Or, elle est envisagée d’abord par le développement d’un apprentissage à destination des enfants. L’enseignement aux adultes passe souvent au second plan que ce soit en termes de revendications par la société civile organisée ou que ce soit en termes de politiques éducatives. A contre-courant, le linguiste gallois Jones affirmait que « dans le processus de restauration de la langue, le facteur déterminant est et doit être l’enseignement aux adultes » (1993). Nous nous proposons d’interroger cette assertion en menant une étude comparative entre l’enseignement à destination des enfants et celui à destination des adultes en Bretagne. Après avoir exposé les arguments avancés par Jones, nous les mettrons en tension avec la situation sociolinguistique du breton. Quelles différences entre l’apprentissage des adultes et des adolescents ? Quel désir anime chacun des groupes d’âges ? De quelle manière les adultes et les adolescents envisagent-ils leurs socialisations langagières une fois l’apprentissage terminé ?
Assessment of the Effectiveness of Team-based Learning Activities on Learning Outcomes in the Undergraduate Immunology Classroom
Authors: Baty Joshua J , Bruns Heather A 
Published: January 2024

Abstract
Immunology is inherently interdisciplinary. Understanding how the immune system functions requires knowledge from several scientific disciplines, including molecular biology, cellular biology, genetics, and biochemistry. Furthermore, immunology is conceptually complex, requiring the identification of a plethora of immune components and mastery of a large volume of new vocabulary. These attributes can pose challenges to student learning in the undergraduate immunology classroom. Team-based learning (TBL) is a pedagogical method used to increase student engagement in learning, improve student collaboration, and develop communication skills. In a variety of educational settings, TBL activities have been shown to foster a deeper understanding of complex topics, increase student confidence in course content, and improve learning outcomes. In this study, we examined differences in the impact of traditional lecture versus TBL activities on student learning outcomes for four different topics presented in an undergraduate adaptive immunity course composed largely of academically high-performing students. We matched content across two student cohorts, delivered via team-based learning methodology (T cell development and Ab-mediated functions) and traditional lecture (B cell development and T cell effector functions). Student learning was assessed using content questions across a range of Bloom’s taxonomy levels, which demonstrated that the TBL activities did not improve examination performance over lecture-based learning in this course. However, students found this learning tool to be valuable, indicating that the TBL activities assisted with preparation for examinations and provided a necessary opportunity to address misconceptions.

Abstract
It is becoming clear that every organ is seeded by a population of fetal liver–derived macrophages that are replaced at different rates by monocyte-derived macrophages. Using the Ms4a3tdTomato reporter mouse that reports on monocyte-derived alveolar macrophages (Mo-AMs) and our ability to examine AM function using our multichannel intravital microscopy, we examined the fetal-liver derived alveolar macrophage (FL-AM) and Mo-AM populations within the same mouse under various environmental conditions. The experiments unveiled that AMs migrated from alveolus to alveolus and phagocytosed bacteria identically regardless of ontogenic origin. Using 50 PFU of influenza A virus (IAV) determined using the Madin–Darby canine kidney (MDCK) cell line, we noted that both populations were susceptible to IAV-induced immunoparalysis, which also led to impaired phagocytosis of secondary bacterial infections. Both FL-AMs and Mo-AMs were trained by β-glucan to resist IAV-induced paralysis. Over time (40 wk), Mo-AMs began to outperform FL-AMs, although both populations were still sensitive to IAV. Our data also show that clodronate depletion of AMs leads to replenishment, but by FL-AMs, and these macrophages do show some functional impairment for a limited time. Overall, the system is designed such that new macrophages rapidly assume the function of tissue-resident macrophages when both populations are examined in an identical environment. These data do differ from artificial depletion methods that compare Mo-AMs and FL-AMs.
The low cross-sectional muscle index at the third cervical vertebra is a marker for sarcopenia in patients with laryngopharyngeal cancer
Authors: Gundog Mete , Kiraz Esin , Eroglu Celalettin 
Published: January 2024

ABSTRACT

Background:
Muscle loss and sarcopenia play a significant role in head and neck cancer. In this study, the value of C3 cross-sectional skeletal muscle index was investigated to evaluate sarcopenia.

Methods:
Seventy-four patients were included in this retrospective study. Skeletal muscle index (SMI) was calculated using the paracervical muscles at the level of the third cervical vertebra. Survival rates and toxicities were compared.

Results:
The 3-year overall survival rates were 33.3% in patients with low SMI (≤44.79) and 63.9% in patients with high SMI (>44.79) (P < 0.01). The 3-year progression-free survival rates were 25.9% in patients with low SMI and 63.2% in patients with high SMI (P < 0.01). Multivariate analyses found that advanced age (>65) was associated with a 2.9-fold increased risk of death and low SMI was associated with a 3.9-fold increased risk of death.

Conclusion:
Low SMI is associated with prolonged treatment time, increased toxicity, and decreased survival.
Mandibular guiding flange prosthesis to guide mandibular deviation following partial mandibulectomy and partial maxillectomy for squamous cell carcinoma: A case report
Authors: Chahal Sujata , Dahiya Divya , Nagar Priya , Duhan Aman , Mittal Surbhi 
Published: January 2024

ABSTRACT
Squamous cell carcinoma is one of the most prevalent cancers affecting the oral cavity. Rehabilitation following surgical treatment requires a multidisciplinary approach and care. Multiple disabilities such as dysarthria, dysphagia, unesthetic appearance, and psychosocial disorders following the surgery for carcinoma can greatly impact the quality of life of such patients, thereby necessitating multidisciplinary intervention. The clinician has to wait for the healing of the lesion and the effects of radiotherapy to be dwindled in case a secondary osseous grafting is planned. During this time lag until a more definitive prosthesis is planned, an interim prosthesis is must to correct the mandibular deviation due to the unilateral muscular pull. This case presentation describes the utilization of guiding flange prosthesis (GFP) as an interim modality for the establishment of a stable and functional maxillomandibular relationship following combined ipsilateral partial mandibulectomy and maxillectomy.

Published: January 2024

ABSTRACT
Maxillofacial rehabilitation of an orbital defect plays a crucial role in enhancing the esthetics of the facial defect. The eye is a vital organ, the loss of which requires a customized approach for post-defect rehabilitation. Advanced treatment option such as implant-supported orbital prosthesis has a superior outcome in terms of retention and esthetics, but due to economic factor, it is not affordable for all patients. This case report describes a simplified rehabilitation technique for a patient with an orbital defect where retention is achieved by spectacles and satisfactory esthetics are obtained.

Published: January 2024

ABSTRACT
Xanthogranulomatous oophoritis is an uncommon form of chronic inflammation of the ovary. Its clinical manifestations, imaging findings, and gross picture can mimic an ovarian neoplasm. Hilar cells, which are morphologically difficult to distinguish from testicular Leydig cells, secrete testosterone and they are mostly seen in the ovarian hilum. They can undergo hyperplasia or can transform into a tumor. We present a case of xanthogranulomatous oophoritis with Leydig cell hyperplasia, which mimicked an ovarian neoplasm.

Published: January 2024

ABSTRACT
Laryngeal squamous cell carcinoma (SCC) is the major subtype, accounting for 90% of cancers at this site. While it has a propensity for locoregional spread to cervical nodes, distant metastasis is seen less frequently and mostly to the lungs, bones, and liver, with an overall incidence of 6.5–7.3%. We hereby report a case of a 61-year-old male previously treated for SCC of the larynx, presenting with an acute intestinal obstruction with the presence of metastatic deposits of SCC in the omentum.

Published: January 2024

ABSTRACT

Background:
Bone metastasis is rarely seen in colorectal cancer (CRC) patients, and there is insufficient data available regarding such cases. The study aimed to identify the prognostic factors and characteristics associated with overall survival in patients with bone metastatic CRC.

Method:
Data from bone metastatic CRC patients referred to a high-volume tertiary cancer center in Turkey, between January 2018 and April 2021, were retrospectively collected. The records of 150 consecutive patients treated for bone metastases due to CRC were reviewed. Overall survival curves were generated by the Kaplan–Meier method and analyzed using the log-rank test.

Results:
Median age was 55 years (19–86 years). Bone metastases were more common in men and those with metachronous metastases. The axial skeleton was the most commonly involved site, and patients were frequently presented with single bone metastasis. Peritoneal metastases were significantly correlated with extra-axial metastases (P = 0.002), and radiotherapy was applied to axial metastases significantly, more frequently (P = 0.02). Lung metastasis was also more prevalent in K-RAS mutated patients (P = 0.008). The median survival time from diagnosis of bone metastasis was 8.3 months (95% confidence interval (CI), 5.5–10.6), and the three-year survival rate was 76.9% (95% CI, 69.8–84.0). Multivariate analysis revealed that brain metastases, right-sided colon tumor, high serum ALP, and Ca 19–9 levels were independent poor prognostic factors (P = 0.01, 0.02, <0.001, and 0.04, respectively).

Conclusions:
The location of CRC correlates significantly with the site of bone metastasis; the prognosis of CRC patients with bone metastasis is very poor, and the significant poor prognostic factors are brain metastases, right-sidedness, high serum ALP, and Ca 19–9 levels. More attention should be paid to bone metastasis in CRC patients.
Complete remission of perineal extra-mammary Paget’s disease by curative-intent radiotherapy using volumetric modulated arc therapy in a patient older than 90 years
Authors: Katano Atsuto , Yamashita Hideomi 
Published: January 2024

ABSTRACT
Localized extra-mammary Paget’s disease (EMPD) is mainly treated with surgical resection. Curative radiation therapy (CRT) is an alternative to surgery. Electron beams and conventional X-ray methods have been used in patients with EMPD for radiotherapy. The present report describes the case of a very elderly patient with perineal EMPD who was treated with definitive radiotherapy consisting of 60 Gy in 30 fractions. Surgery was deemed too difficult because of his age and comorbidities. We adopted volumetric modulated arc therapy as the radiotherapy modality, a recent, advanced form of intensity-modulated radiation therapy. Grade 3 dermatitis was observed as an acute phase adverse event, and he achieved a complete response and maintained remission for over one-year post-treatment. Our radiotherapy treatment protocol resulted in good clinical outcomes; therefore, it may be a candidate for inoperable patients with EMPD.
