Published: November 2024

The Dragonfly Telephoto Array employs a unique design to detect very large and diffuse galaxies that might be missed with conventional telescopes. The Dragonfly Ultrawide Survey (DFUWS) is a new wide-field survey that will cover 10,000 deg2 of the northern sky, and it provides an ideal data set to find these large diffuse galaxies. From 3100 deg2 of DFUWS data, we identified 11 large, low surface brightness galaxies as a pilot sample for spectroscopic follow-up. These are the largest galaxies in the examined area that appear smooth and isolated, with effective radii of 12″–27″. Eight are below 24

in central g-band surface brightness. Keck Cosmic Web Imager spectra of the diffuse light show that all 11 galaxies in this sample are quiescent, and seven qualify as ultradiffuse galaxies (UDGs). Eight galaxies have distances between 15 and 30 Mpc, while the other three are in the Pegasus cluster at 50 Mpc. Their spectra show evidence of a ∼1 Gyr old stellar population in addition to an even older stellar population. The intermediate-age component is present in group and satellite galaxies but not in the Pegasus cluster UDGs. All galaxies in this sample are detected in both Dragonfly and Legacy imaging, and the sample partially overlaps with existing UDG catalogs. This pilot sample provides an excellent training set for our analysis of the upcoming full 10,000 deg2 DFUWS data, from which we may expect to discover even larger, previously unknown galaxies.
A two- to three-dimensional wake transition mechanism induced by the angle of attack of a NACA0012 airfoil
Authors: Kokash Hussein , Agbaglah G. Gilou
Published: November 2024

A high-order spectral element method was used to perform three-dimensional direct numerical simulations of the flow past a NACA0012 airfoil. We considered a Reynolds number $ Re = 1000 $ and two different angles of attack, $ \alpha = 11^\circ $ and $ \alpha = 16^\circ $, to study the two- to three-dimensional wake transition. A boundary layer separation was observed for both angles of attack with the separation point closer to the leading edge for $ \alpha = 16^\circ $. The downstream of the airfoil exhibited streamwise vortical structures formed in the braid regions connecting the primary vortices for $ \alpha = 16^\circ $, while only shed vortices were observed for $ \alpha = 11^\circ $. The formation of these streamwise structures were explained by the presence of a reverse flow from the lower surface for $ \alpha = 16^\circ $, enhancing shearing effects. The early-stage development of the three-dimensional wake, in the case of $ \alpha = 16^\circ $, was characterized by the formation of a spanwise sinusoidal velocity whose amplitude increased exponentially over time. The flow on the upper surface experienced a higher strain field which pulled up small disturbances from the airfoil surface and formed regions of concentrated vortical structures. These structures were subjected to stretching under the strain field and later advected downstream of the airfoil.
Imágenes sagradas y espacios para la devoción en los hogares valencianos en la baja Edad Media
Authors: Izquierdo Aranda Teresa
Published: November 2024

En los últimos siglos de la Edad Media, las imágenes de culto desempeñaron un papel primordial en el interior del hogar. En la sociedad valenciana fue fundamental la influencia de las corrientes espirituales difundidas gracias a la predicación mendicante que dio como resultado una extraordinaria presencia de imágenes en el interior de las viviendas. La documentación notarial nos ha descubierto una amplia variedad de piezas devocionales en los ajuares domésticos, así como los complementos utilizados para ornamentar esos espacios reservados a la oración. Nos permite conocer lo que el espectador contemporáneo encontraba en las representaciones en su quehacer diario para indagar en esa relación entre la obra y su espectador, entre el arte y la religiosidad como expresión de la cultura.
Tejidos de solidaridad de los pintores novohispanos del siglo XVIII en la Ciudad de México, o bajo el escrutinio social: del prejuicio al prestigio
Authors: Mues Orts Paula
Published: November 2024

El centro del trabajo es el análisis de las redes de solidaridad que los pintores de la ciudad de México tendieron al clérigo criollo novohispano Agustín Rodríguez Medrano, quien entre 1760 y 1779 tuvo que probar su limpieza de sangre para obtener grados mayores en la Real Universidad de México y ser admitido al Real Colegio de Abogados. A raíz de rumores sobre su posible origen mulato, se levantaron informaciones. Al ser nieto del pintor Francisco Javier Vázquez, once artistas testificaran en diversas ocasiones a favor suyo. La documentación aporta datos valiosos hasta ahora desconocidos sobre artífices como Miguel Cabrera, Miguel Rudecindo Contreras y Manuel Carcanio y permite reconstruir aspectos relevantes acerca de las relaciones sociales de los pintores de la ciudad de México, sus estrategias de solidaridad grupal y sus relaciones con importantes intelectuales y funcionarios.

Published: November 2024

In this study, we propose the use of a convolutional neural network (CNN) (2+1) D-based model for the non-invasive detection of iron deficiency anemia using smartphones, addressing the need for accessible and efficient diagnostic methods. We have collected fingertip images from 909 young people, creating a robust dataset to train and validate the model through machine learning (ML), providing us with both spatial and temporal information. Our approach stands out for its simplicity and potential to be implemented in diverse contexts, which facilitates early and accurate diagnosis of anemia. The results show remarkable performance indices in the validation set: an accuracy of 0.9840, a precision of 0.9830, a sensitivity (recall) of 0.9840, an F1-Score of 0.9835, and an AUC ROC of 0.9878, demonstrating the model’s high ability to effectively classify anemic states. These findings validate the efficacy of the model to significantly improve the detection of iron deficiency anemia, promoting the use of mobile technologies and machine learning for more accessible and efficient diagnosis globally. This breakthrough marks a significant step towards improving access and efficiency in health diagnostics through smartphone technology and machine learning, opening new avenues for the effective management of anemia and other health conditions.

Published: November 2024

Medical equipment management by using computerized systems is a key success of medical equipment maintenance and repair in hospitals. This system, which is installed in the biomedical engineering department, mostly provides an important management function for equipment registration, repair maintenance, and spare part administration. This study presents the development and evaluation of the WepMEt second version platform for managing medical equipment in hospitals across Thailand. The study focused on an improvement and expanding functionality in five key modules: equipment registration, preventive maintenance, repair, spare parts management, and equipment pooling modules, utilizing a rapid prototyping development method. Feedback information from 15 hospitals and primary criticism from five experts in medical equipment management were intently incorporated to improve an original version. Then, the post-development system was assessed in an intensive hands-on training workshop by 23 users from 16 hospitals, both nurses and biomedical engineers, and also the expert, in order to evaluate a satisfaction comment. The results show that our new WepMEt platform was highly accepted, with an average score of 4.73 and 4.75 for the expert team and all users, respectively. Most summarized comments clearly demonstrate effectiveness in comprehensively meeting the user needs, improving management efficiency significantly, and also reducing workload in hospitals. Our future work will be focused on AI technology to facilitate a modernized hospital by integrating administrative decision-making models for equipment maintenance management, enhancing the smart user interface, and incorporating an IoT and cloud computing technology to support real-time equipment tracking.

Authors: Shkurti Lamir , Selimi Mennan
Published: November 2024

Federated learning (FL) presents a decentralized approach to model training, particularly beneficial in scenarios prioritizing data privacy, such as healthcare. This paper introduces AdaptiveMesh, an FL adaptive algorithm designed to optimize training efficiency in heterogeneous wireless environments. Through dynamic adjustment of training parameters based on client performance metrics, including central processing unit (CPU) utilization and accuracy trends, AdaptiveMesh aims to enhance model convergence and resource utilization. Experimental evaluations on heterogeneous client devices demonstrate the algorithm’s effectiveness in improving model accuracy, stability, and training efficiency. Results indicate a significant impact on CPU adaptation in preventing client overloading and mitigating overheating risks. Furthermore, the results of the one-way analysis of variance (ANOVA) and regression analysis highlight significant differences in CPU usage, accuracy, and epochs between devices with varying levels of hardware capabilities. These findings underscore the algorithm’s potential for practical deployment in real-world edge computing environments, addressing challenges posed by heterogeneous device capabilities and resource constraints.
Evaluation of Optimization Algorithms for Use in a Mobile App Aimed at Learning Autotuning of PID Controllers for Engineering Students
Authors: Chamorro-Atalaya Omar
Published: November 2024

Most research in the field of optimization algorithms related to automatic control, both in Hessian and quadratic methods, does not pay enough attention to computational efficiency in data processing, especially in mobile applications on smartphones where their resources are limited. This study seeks to identify the most efficient algorithm in terms of resource consumption for autotuning of PID (proportional, integrator, derivative) controllers in a mobile app aimed at learning engineering students. The BFGS (Broyden-Fletcher-Goldfard-Shanno), simulated annealing, genetic, conjugate gradient, and PSO (particle swarm optimization) algorithms were evaluated. The descriptive scope research and quasi-experimental design showed that the BFGS algorithm is highly efficient and suitable for autotuning of PID controllers in mobile applications, demonstrating consistency in the use of resources with different numbers of testing samples. This study validates a useful optimization method to develop a mobile app that simulates the tuning of PID controllers, being useful for learning topics about automatic control of industrial processes, which allows closing gaps in accessibility and educational availability for engineering students. Future studies should focus on developing mobile applications that use smartphone sensors to generate signals in real time and integrate them with augmented reality environments to build immersive and interactive autotuning systems.

The Tendency to Accept Entrepreneurial Endeavors among Future Generations
Authors: Gnanaweera Kamal , Manta Otilia
Published: November 2024

The study aims to investigate whether students, after finishing their university education and receiving an entrepreneurship education, have a significant tendency to pursue entrepreneurship as a lifelong pursuit rather than choosing traditional career paths in the public or private sectors. In addition, the study aims to clarify the significance of encouraging economic growth among college students at a National university in Sri Lanka. The research employed a quantitative approach with a descriptive study design to provide a detailed analysis of entrepreneurship education for future research. This study employed a structured questionnaire as an instrument for polling to assess students’ views on the efficacy of entrepreneurship education. The study sample consisted of 76 students who had successfully finished the entrepreneurship course during their first year from the Applied Sciences Faculty and were studying different combinations of science streams together with management modules. Six hypotheses are formulated to address the specific objectives of the research. The study’s findings revealed that most students do not believe that the education system in Sri Lanka effectively delivers the needed entrepreneurial education, which is crucial for the country’s economic development. Students strongly believe that the government fails to emphasize the right requirements for improving the entrepreneurial education system in Sri Lanka. Moreover, students acknowledge that they do not intend to pursue future entrepreneurial endeavors. Most students do not believe that the university curriculum adequately and necessarily prepares them with the necessary vocational training to enhance their preparedness and desire for entrepreneurship. Additionally, the research findings indicate that undergraduates who are pursuing a scientific major at Sri Lankan National University have a restricted sense of locus of control. The exploration of these results takes into account the existing knowledge and the unresolved aspects of the current national education systems to identify the hidden innovation in the prospects for the future of the younger generation in the country as they relate to national economic growth.
Future of Work: Working from Home. Empirical Evidence from the Chinese Economy
Authors: Jahangir Junaid , Ahmad Munir
Published: November 2024

The present analysis elucidates the estimates of the proportion of the non-agricultural workforce that can potentially work from home (WFH) in China. The current analysis explains the estimates of China’s non-agricultural workforce’s ability to WFH to address the inadequate research on remote work adaptability in emerging economies. The considerable demographic and regional disparities in WFH potential we found are noted here. To measure the possibility of WFH, our empirical outcomes revealed that the probability of working remotely from home is higher for youth and middle-aged workers residing in urban areas and belonging to nuclear families. Education is observed to strongly interconnect with working remotely—individuals with higher education are more likely to WFH. In addition, workers working in white-collar occupations have a higher probability of WFH than those in lower-skilled occupations. Further investment in developing information and communication technology (ICT) infrastructure in the economy to improve the productivity of the country’s workforce is an essential area of policy action that emerges from the analysis.

Where was Lawrence chez-lui?
Authors: Bell Michael
Published: November 2024

If “transcendental homelessness” is the modern condition, Lawrence is an especially instructive example of how to live within it. His emigré life, partly imposed and partly chosen, was experienced with a vivid appreciation of the “spirit of place,” and of places. Perhaps for Lawrence to be at home was a cosmic state experienced most intensely through a life on the move. Martin Heidegger similarly speaks of dwelling as a state of Being and invokes Hölderlin’s words “poetically, man dwells on this earth.” But home is a temporal as well as a spatial location and whereas Heidegger privileges the rootedness of ancestral continuity, Lawrence, who also dwelt poetically, seems to seek a world always new, or renewed. The present paper seeks to illustrate this contrast by examining several moments in the oeuvre.
The Chronotope of Home in The Rainbow: Place, Time and Identity
Authors: Ragachewskaya Marina
Published: November 2024

Home in contemporary culture is acquiring ontological value due to our changing globalized world. In Lawrence’s fiction, the concept of home is an important metaphor of self and identity. In this paper, I apply Mikhail Bakhtin’s theory of the chronotope to elucidate the meaning and role of home in identity creation, drawing on a reading of The Rainbow. The static (place) and the dynamic (time) qualities of the home chronotope are catalysts of the action and feeling for most of the Brangwen family members. Home is mostly an enclosed static space, which magnetically draws its inhabitants. Life whirls and bubbles around it, making it dynamic as well – from the nineteenth-century agricultural domestic arrangements to the change and flux of the early twentieth century. Thus the stability of home is constantly disrupted by changes, newcomers, by life itself. Ursula’s identity as one of the Brangwen women whose eyes remain turned to the outside world, but who are their own selves only within the enclosure of their home, is formed by the complementary drives of leave taking and home-coming. The threshold, both the symbolic image and Bakhtinian chronotope, is constantly present in the narration, marking the crucial moments in the characters’ lives. Ursula’s identity undergoes such changes and becomes firmly established as a Brangwen woman.

Authors: Mpofu Limkile , Moyo Idah , Mavhandu-Mudzusi Azwihangwisi H.
Published: November 2024

Background: The focus of this study was on women living with HIV in rural Zimbabwe, who face many challenges, both in the family and community. Patriarchy compounds these problems as these women navigate access to health and other services.Objectives: The study sought to explore ubuntuism and the sociocultural factors that facilitate or constrain women living with HIV from accessing community services and resources.Method: An interpretive phenomenological analysis research design was utilised for the study. Purposive and quota sampling were applied to recruit 40 participants from six villages. Data were collected using in-depth interviews and focus group discussions that were audio recorded and transcribed. The data were analysed using the interpretive phenomenological analysis framework.Results: The study found that women living with HIV face stigma and discrimination in the form of social exclusion and reduced access to community-based health activities and empowerment opportunities. These challenges were compounded by the negative impact of patriarchy that gives rise to land, resettlement and acculturation challenges.Conclusion: Ubuntu is a reflection of mutual dependence and can be used to promote more compassionate relationships with those who are HIV positive in the community.Contribution: The study provides unique insights into the challenges experienced by women living with HIV and how ubuntu could mitigate those challenges so that it adds to the humanistic philosophies in interpersonal relationships.
Negotiating tradition and change in pastoral training in the Church of the Nazarene in Africa
Authors: Solomons Lloyd , Mtukwa Gift , Naidoo Marilyn
Published: November 2024

This article highlights the tension of sustaining tradition versus the need for change within theological education. Within denominations, there is the challenge of maintaining tradition while at the same time wanting to embrace change. If this is not managed properly, the tradition can become out of date when there is a focus on controlling through enforcing tradition and through indoctrination in education. This article presents the Church of the Nazarene, as a case study, where their theological education is tested against an organic and indigenous framework highlighting the need for a contextual driven curriculum. There are various aspects within the tradition that are slow to adapt, where aspects of Western church polity and practices linger on thereby negatively impact the curriculum. However, if a contextual learning programme does not materialise students’ knowledge from the classroom will not match what they need to know once they reach the ministerial setting. This article examines pastoral training in the Church of Nazarene’s southern African region to emphasise the dichotomy between preserving tradition and the need to innovate in order to ensure its long-term viability.Contribution: This article reflects on the important balance of sustainability in a global church tradition, and it serves as a case study of issues commonly found in many denominations. It is about holding on to the core teachings that has stood the test of time but having the ability to be adaptative to the contextual needs of a region. Reasons are provided for the slow pace in change and ways to overcome this. This article contributes to the literature on the Church of Nazarene.
Successful aortic root enlargement with redo aortic valve replacement in a 73-year-old male
Authors: Puranik Manish
Published: November 2024

Aortic valve prosthesis implantation in native aortic annulus poses inherent drawback of implanting, smaller sized valve. To reduce this disparity, various root enlargement procedures are used in practice. We report a case in which a novel technique of root enlargement was used in a redo valve replacement scenario. A 73-year-old male presented with a history of breathlessness dyspnea on exertion. Since few months, he had undergone aortic wall replacement with a 19 mm bioprosthetic in 2016, diagnosis of structural wall deterioration with severe aortic reached gnosis stenosis was confirmed by echocardiography. The patient was subjected to redo sternotomy, degenerated prosthesis was explanted. Recently devised technique of aortic root enlargement was used and a much larger prosthesis was implanted. Postprocedure, the patient was observed in the cardiac recovery room for 2 days. The patient was discharged without any very operative complications on day 8 of surgery. The novel root enlargement procedure devised by bow. Yang at all, is simple, reproducible and less complicated and easily replicable even in redo valve replacement scenario.
Unusual case of pretricuspid left to right shunt undergoing device closure – A persistent left levoatrial cardinal vein masqueraded by small ostium secundum atrial septal defect
Authors: Sapre Ashish , Sreekar M. C. V. , Reddy V Nihanth , Kapavarapu Pavan Prasad
Published: November 2024

The levoatrial cardinal vein (LACV) is a rare persistence of embryonic remnant of connection between systemic and pulmonary venous system. LACV is a vascular anomalous connection between the left atrium and the superior vena cava (or left innominate vein). Usually, these anomalous connections are associated with left-sided obstructive lesions. We are reporting a case of LACV with small ostium secundum atrial septal defect (ASD), with nonobstructive bicuspid aortic valve with significant pretricuspid left to right shunt with mild pulmonary arterial hypertension. Successful occlusion of LACV with Amplatzer Vascular Plug II was performed.

Learning Objective:

This case report cautions us to consider the presence of LACV as a possible explanation in infants or children with right-heart volume overload which is out of proportion to the small ostium secundum ASD. Transcatheter closure is effective in dealing with this congenital lesion.
A groupoid approach to the Wodzicki residue and the Kontsevich–Vishik trace
Authors: Mohsen Omar
Published: November 2024

Building on the work of Debord and Skandalis, van Erp and Yuncken introduced a groupoid approach to pseudo-differential operators which has various advantages over the classical approach using Hörmander’s symbolic calculus. In a recent work by Couchet and Yuncken, they showed that for pseudo-differential operators of order

On Brauer–Manin obstruction to the Hasse principle and weak approximation for homogeneous spaces under connected reductive groups over global fields
Authors: Thang Nguyen Quoc
Published: November 2024

We give some new formulas via some exact sequences for computing an obstruction to the weak approximation on non-abelian cohomology sets and homogeneous spaces over global fields, with stabilizers belonging to some class of non-connected subgroups. As a consequence, we show that the Brauer–Manin obstruction to the weak approximation for such spaces is the only one. Along the way, we show that the Brauer–Manin obstructions to the Hasse principle and weak approximation for homogeneous spaces under connected reductive groups over global function fields with stabilizers belonging to a certain class of non-necessarily connected groups are the only ones, extending some of Borovoi’s results obtained for number fields in this regard.

Screening and evaluation of diabetic retinopathy via a deep learning network model: A prospective study
Authors: Yao Li , Cao Chan-Yuan , Yu Guo-Xiao , Shu Xu-Peng , Fan Xiao-Nan , Zhang Yi-Fan
Published: November 2024

BACKGROUND

Diabetic retinopathy (DR) is one of the most common serious complications in diabetic patients, and early screening and diagnosis are essential to prevent visual impairment. With the rapid development of deep learning technology, network models based on attention mechanisms have shown significant advantages in medical image analysis, which can improve the accuracy and efficiency of screening.

AIM

To evaluate the efficacy of an attention mechanism-based deep learning network model in screening for DR in natural and diabetic populations, as well as in screening with unilateral and bilateral fundus photography.

METHODS

From January 2023 to June 2024, a stratified multistage cluster sampling method was adopted to select a representative sample of permanent residents aged 18-70 years from our hospital. A total of 948 fundus images from 474 participants were included in the "deep learning model" system for scoring. The fundus images were graded via the early treatment of DR [Early Treatment Diabetic Retinopathy Study (ETDRS)] scoring system as the gold standard for the diagnosis of DR. With "DR to be referred (ETDRS > 31)" as the reference variable, a receiver operating characteristic curve was drawn to evaluate the area under the curve (AUC), sensitivity and specificity of the "deep learning model" to determine the screening efficiency of the system.

RESULTS

For each subject, in the natural population, the AUC of using the "deep learning model system" to screen "DR-requiring referral" was 0.941, and the sensitivity and specificity were 98.15% and 90.08%, respectively. The sensitivity and specificity of two-directional fundus photography were 100% and 86.91%, respectively. In the diabetic population, the AUC, sensitivity and specificity were 0.901, 98.08% and 82.10%, respectively, when "wise eye sugar net" unilateral fundus photography was used to screen for "DR-requiring referrals".

CONCLUSION

In both the natural population and the diabetic population, the deep learning model system has shown high sensitivity and specificity and can be used as an auxiliary means of DR screening.
Promise of the gut microbiota in prevention and traditional Chinese medicine treatment of diabetic peripheral neuropathy
Authors: Cao Yuan-Hao , Zhou Yi-Mai , Wang Si-Yu , Guo Jing , Cen Lu-Sha
Published: November 2024

The pathogenesis of diabetic peripheral neuropathy (DPN) has not been fully elucidated, and treatment options are limited. Currently, the main strategies for treating DPN are strict glycemic control and symptomatic pain relief. In this editorial, we comment on an article by Li et al, which suggested that modulating the gut microbiota using traditional Chinese medicine (TCM) may be a promising strategy for alleviating DPN symptoms. The regulation of the gut microbiota has received widespread attention in the study of various diseases. TCM can participate in the regulation of gut microbiota through multiple mechanisms, and this regulatory effect can alleviate the clinical symptoms of DPN. We briefly analyzed the promise of the gut microbiota in the early diagnosis, treatment, and clinical efficacy of TCM for DPN. The gut microbiota has potential value at multiple nodes in the occurrence and progression of DPN.

Literary Works as Testimony to Non-Indifference: On the Pedagogical “Shading” of Janusz Korczak’s Oeuvre
Authors: Cybal-Michalska
Published: November 2024

Each epoch leaves its own literary mark. The discourse of humanities concerning literary works as a reception of historically transformed social reality and socio-cultural experiences should include a reflection on the testimony of (non) indifference. The presentation referring to the pedagogical “shading” of Janusz Korczak’s works will be a pretext for considering literature as a testimony of presence in social experiences but will also direct cognitive interests towards behaviour and interpersonal relations. Thus, analyses of the social conditions that resulted in Janusz Korczak’s literature and, above all, reflections on what social effects it caused and continues to cause are cognitively fascinating. Thus, by embedding literature as a cultural feature in a network of social relations, it is worth reflecting on the type, not only of knowledge, but of psychological predispositions that can be reproduced in it, taking the quality of socio-cultural reality as a point of reference.
Siła języka. Jak uczyć dzieci nadziei?
Authors: Murawska Anna
Published: November 2024

W artykule autorka wskazuje na specyfikę edukacji wczesnoszkolnej ze szczególnym uwzględnieniem niespójności między rangą przyznawaną temu etapowi edukacji a jego jakością ujawnianą w licznych badaniach. Pokazuje też problematyczność dzieciństwa ujmowanego w kontekście nadziei, zwracając uwagę na to, że nadzieja nie jest automatycznie przypisana do tego okresu życia człowieka. Tak jak inne dyspozycje człowieka wymaga wspierania w rozwoju. Ze względu na rolę, jaką odgrywa język w poznawaniu, rozumieniu i interpretowaniu świata, autorka stawia tezę o konieczności refleksji nad językiem, którym posługują się nauczyciele wczesnej edukacji. Proponuje, aby w refleksji tej brać pod uwagę sformułowane przez nią cechy „języka nadziei”.

Recently, cancer has been identified as the leading cause of death worldwide. Commercially available cytotoxic immunotherapies and other conventional therapeutics have been developed and made accessible to the general population. Immuno-cell therapy is an innovative therapeutic approach that has dramatically transformed the field of cancer treatment. This specific immunotherapy modality utilizes viable immune cells as therapeutic agents to combat cancer. In contrast to traditional medications, cell treatments are classified as "living drugs" and need personalized medicine and sophisticated production methods. A novel therapeutic T cell engineering technique known as "chimeric antigen receptor" T cell therapy involves modifying T cells obtained from various individuals in a laboratory setting to produce synthetic receptors targeting a cancer antigen. Directly detecting the tumor antigen does not rely on the primary histocompatibility complex. Recent studies have shown that this drug may reduce remission rates for hematologic malignancies by as much as 80%. The therapy has demonstrated notable efficacy in treating acute lymphoblastic leukemia (ALL) and lymphomas characterized by giant B cells in the B cell line. Although recombinant antigen receptors (CAR)-T cell treatments have captured the industry's attention for treating hematological malignancies, their limited effectiveness in solid tumors has led to the creation of alternative immune cell-based therapies. Dendritic cell (DC) vaccines, cytokine-induced killer (CIK) cell therapy, and tumor-infiltrating lymphocyte (TIL) therapy using cells are medical interventions that specifically target and eradicate cancer cells by utilizing the body's defensive mechanisms.

This work presents a review of mechanical centrifugation and pyrolysis, two prominent techniques used for the efficient management of oil refinery sludge. The petrochemical industry produces large quantities of hazardous oily sludge, which demands complex and costly treatment methods due to its diverse composition. However, a major component of this sludge is crude oil, which holds significant recycling potential. As a result, various technologies, including combined processes, have been developed to recover crude oil from sludge. This study evaluates the effectiveness of combining mechanical centrifugation and pyrolysis, specifically focusing on their oil recovery capabilities. The primary objective is to explore the development of these recycling technologies while summarizing and comparing their mechanisms, advantages, and limitations.

Mirativity in Persian
Authors: Rasekh-Mahand Mohammad
Published: November 2024

Mirativity, as a distinct grammatical category, could be marked by different markers and strategies. In this paper, it is argued that, contrary to previous studies, Persian marks mirativity by using morphosyntactic forms. Three different grammatical tools are identified. First, it has a sentence final clitic ‘=ā’ used as mirative marker on its own right. It indicates that the information is newsworthy, unexpected and surprising. Second, the sentence final particle 'ke', among its different functions, marks mirativity, as well. Third, using different perfect verb forms in Persian is a mirative strategy, which is strongly connected to indirect evidentiality. The data from Persian widens our understanding of mirativity cross-linguistically, showing that a language could have different ways to mark it simultaneously.
Low vowel dissimilation in Mazandarani
Authors: Mahdavi Mazdeh Mohsen , Nehzati Sarah
Published: November 2024

Similar patterns of vowel change in loanword adaptation have been documented for several Iranian languages and language varieties including Mazandarani. However, no convincing accounts of the nature of these processes in Mazandarani have been presented in the literature. We argue that for this language, these vowel alternations are best explained as low vowel dissimilation, a process affecting adjacent syllables with low vowels whereby one of the vowels is raised. Low vowel dissimilation is typologically rare, with the overwhelming majority of the cases identified belonging to the Oceanic family. To show that the vowel changes in question are indeed cases of low vowel dissimilation, we invoke evidence from the language’s verbal morphophonology where vowel changes show a more regular behavior and then expand the analysis to loanword adaptation. The dialects discussed in the articles are those of Amol, Reineh, and Babol. The two vowels that trigger the process in Mazandarani are the low vowels /æ/ and /ɑ/, but only the former can undergo change. We show that unlike almost all other known cases of this phenomenon, it is the second vowel that undergoes raising in the Mazandarani case in many situations, with this seemingly being the preferred way in the dialect of Babol. We end the paper with a discussion of why the two low vowels behave differently, suggesting that /ɑ/’s resistance to change is due to the fact that it is a long vowel phonologically, even if not phonetically.
