Experiments and Interventions: Re-envisioning Qualitative Research Methods in Migration
Authors: Kumar Alka 
Published: October 2023

AbstractThe purpose of this chapter on methodology is manifold. It begins by telling the story of the StOries Project, a migration-centred teaching-training initiative that started in 2021 at CERC, in Migration at Toronto Metropolitan University. Using narrative enquiry to delve into the lived experience of migration, employing creative writing formats, was one of its core objectives. Our intention was also to explore the potential of the above conceptual paradigm and methodological process to learn more, and also ‘differently,’ about the migration experience. As the stories- written mostly in a personal and creative non-fiction style- and the academic chapters in this hybrid collection demonstrate, if such experimental projects in migration garner interest from students, early-stage researchers and academics searching for new areas and methods of exploration in this field, pioneering work in cross disciplinary fields could be brought in conversation with each other; and insights from such contributions would help bring new ways of seeing and thinking to migration studies, helping both academic and mainstream readers to ‘know’ about the migration journey more from the perspective of individuals who have experienced it.
The Research Memoir of an Intra-EU Migrant Who Has Become a Guest in a Settler Colonial State
Authors: Triandafyllidou Anna 
Published: October 2023

AbstractI started my graduate studies, outside my own country of origin (Greece), in 1990 at a time when the whole of Europe was experiencing a reconnection; a new sense of freedom, a novel enthusiasm, a set of landslide social, economic and political changes, similar to a quiet revolution. Migration has been a very important part of this post-1989 ‘revolution’ in Europe. And it has swept me and my post-doctoral studies into it, moving my career compass from the study of minority parties to migration and integration research. This chapter offers a self-reflexive, almost auto-ethnographical account of how my life and my work have been intertwined. I am looking into how my readings and writings have reflected to some extent my experiences while also helping to dissect and analyse those. Naturally my family, my husband and four children, have been drawn, willy nilly, into this great transnational journey. The aim of this chapter, as with our whole book, is to blend the academic with the creative writing in an effort to enrich our understanding of international migrations.
How I Became an Alevi Muslim Woman
Authors: Ari Esra 
Published: October 2023

AbstractI (Esra) explore my personal journey- of “becoming” an Alevi Muslim woman, as it unfolded while travelling in the US, and now, living in Canada. Previously, while living in Türkiye, I did not particularly self-identify with a religious identity. I narrate (and interrogate) how my identity construction process has been shaped by others’ perceptions and assumptions of who I am. My personal story is intertwined with the stories of my homeland (Türkiye), Canada and the US.
Journey Through the Self
Authors: Richards Chelsea Nyomi 
Published: October 2023

AbstractThis piece raises critical questions regarding the sense of belonging in 2nd-generation Canadians, or those born in Canada to one or more immigrant parents. I am a multidisciplinary artist and a storyteller of Jamaican heritage, often describing myself as a wanderer due to not truly feeling at home anywhere. My interests surrounding cultural identity stem from my discontent with not feeling Jamaican enough, while simultaneously feeling misunderstood as a culturally marginalized Canadian. My experiences with isolation and my yearning to belong were the inspiration for this story.
Degenerate Perturbation Theory for Models of Quantum Field Theory with Symmetries
Authors: Hasler David , Lange Markus 
Published: October 2023

AbstractWe consider Hamiltonians of models describing non-relativistic quantum mechanical matter coupled to a relativistic field of bosons. If the free Hamiltonian has an eigenvalue, we show that this eigenvalue persists also for nonzero coupling. The eigenvalue of the free Hamiltonian may be degenerate provided there exists a symmetry group acting irreducibly on the eigenspace. Furthermore, if the Hamiltonian depends analytically on external parameters then so does the eigenvalue and eigenvector. Our result applies to the ground state as well as resonance states. For our results, we assume a mild infrared condition. The proof is based on operator theoretic renormalization. It generalizes the method used in Griesemer and Hasler (Ann Henri Poincaré 10(3):577–621, 2009) to non-degenerate situations, where the degeneracy is protected by a symmetry group, and utilizes Schur’s lemma from representation theory.
A singular stochastic control problem with direction switching cost
Authors: Kruk Łukasz 
Published: October 2023

AbstractWe introduce a new class of singular stochastic control problems in which the process controller not only chooses the push intensity, at a price proportional to the displacement caused by his action, but he can also change the allowable control direction, paying a fixed cost for each such switching. Singular control of the one-dimensional Brownian motion with quadratic instantaneous cost function and costly direction switching on the infinite time horizon is analyzed in detail, leading to a closed-form solution. This example is used as an illustration of qualitative differences between the class of problems considered here and classic singular stochastic control.
Banking diversity and firms’ exit: A study on Italian data
Authors: Costanzo Giuseppina Damiana , Succurro Marianna , Trivieri Francesco 
Published: October 2023

AbstractWith Italian data, this paper investigates the role of institutional banking diversity on firms’ exit. Using the Gini–Simpson index, a measure of biodiversity drawn from ecological sciences, we find that banking diversity would have reduced firms’ exit rates in the period under investigation (2009–2020), and such a beneficial effect appears sharper for the years of the last financial–sovereign crisis. Both of these findings seem to support the “biodiversity argument” pioneered by Ayadi et al. (2009, 2010), stating that – beyond the merits of any particular bank institutional model – it is indeed the coexistence of a mix of different credit institutions that matters in favouring the financing of the real economy, especially in a scenario characterized by financial turmoil and uncertainty. As a policy recommendation, authorities should promote regulations that, avoiding bias towards a specific bank model, aim to preserve and promote biodiversity in the banking sector.

Published: October 2023

AbstractRadical prostatectomy and radiation therapy are the standard treatment options for localized prostate cancer (PC). However, radical prostatectomy may cause the deterioration of urinary and sexual function, and radiation-induced hemorrhagic cystitis and severe rectal bleeding are risk factors for fatal conditions in patients after radiation therapy. With the recent development of magnetic resonance imaging (MRI) for the localization of clinically significant PC (csPC) and treatment modalities, “focal therapy”, which cures csPC while preserving anatomical structures related to urinary and sexual functions, has become a minimally invasive treatment for localized PC. Based on the clinical results of transrectal high-intensity focused ultrasound (HIFU) for localized PC in the whole gland and focal therapy, HIFU is considered an attractive treatment option for focal therapy. Recently, the short-term clinical results of transurethral high-intensity directional ultrasound (HIDU) have been reported. With the resolution of some issues, HIDU may be commonly used for PC treatment similar to HIFU. Because HIFU and HIDU have limitations regarding the treatment of patients with large prostate calcifications and large prostate volumes, the proper use of these modalities will enable the treatment of any target area in the prostate. To establish a standard treatment strategy for localized PC, pair-matched and historically controlled studies are required to verify the oncological and functional outcomes of ultrasound treatment for patients with localized PC.
Sunspot Observations at the Eimmart Observatory: Revision and Supplement
Authors: Vokhmyanin Mikhail , Zolotova Nadezhda 
Published: October 2023

AbstractDigital images of sunspot drawings of the archives of Georg Christoph Eimmart stored at the National Library of Russia, St. Petersburg, are analyzed to obtain sunspot-group numbers and sunspot areas as well as heliographic positions. Overall, more than a hundred drawings were processed. The impact of drawing and reproduction uncertainties and the aims of historical observations are considered. The sunspot positions are compared to those reported by contemporary observers of the Maunder minimum. The restored sunspot-group numbers and latitudes are compared to those extracted by Hoyt and Schatten (Solar Phys. 179, 189, 1998) as well as Hayakawa et al. (Solar Phys. 296, 154, 2021b) and Hayakawa et al. (Astrophys. J. 909, 166, 2021d). The persistence of long-lived sunspots over several solar rotations is discussed.

Abstract
Background
Patellar femoral chondropathy (FPC) is a common problem in patients undergoing anterior cruciate ligament reconstruction (ACL-R) surgery, which, if left untreated, predisposes to arthrosis. Magnetic resonance imaging (MRI) is the non-invasive gold standard for morphological evaluation of cartilage, while in recent years advanced MRI techniques (such as T2 mapping) have been developed to detect early cartilage biochemical changes. This study evaluates the different onset of early PFC between B-TP-B and HT through T2 mapping. Secondly, it aims to assess the presence of any concordance between self-reported questionnaires and qualitative MRI.

Materials and methods
19 patients enrolled were divided into two groups based on the type of intervention: B-PT-B and HT. After a median time of 54 months from surgery, patients were subjected to conventional MRI, T2 mapping, and clinical-functional evaluation through three self-reported questionnaires: Knee Injury and Osteoarthritis index (KOOS); Tegner Lysholm Knee Scoring Scale; International Knee Documentation Committee (IKDC).

Results
There is not statistically significant difference in the comparison between the two MRI techniques and the two reconstructive techniques. KOOS and Tegner Lysholm scales showed significant agreement with MRI results on the grading of chondropathy.

Conclusions
There are no differences between B-TP-B and HT techniques in the early development of PFC detectable through non-invasive methods. Due to the large reduction in the frequency of physical activity following ACL-R and the finding of mild PFC (grade I and II) in a substantial proportion of patients, after a relatively short period from ACL-R, all patients should undergo conservative treatment.
Temporal to spatial instability in a flow system: a comparison
Authors: Barletta Antonio 
Published: October 2023

AbstractThe definitions of temporal instability and of spatial instability in a flow system are comparatively surveyed. The simple model of one-dimensional Burgers’ flow is taken as the scenario where such different conceptions of instability are described. The temporal analysis of instability stems from Lyapunov’s theory, while the spatial analysis of instability interchanges time and space in defining the evolution variable. Thus, the growth rate parameter for temporally unstable perturbations of a basic flow state is to be replaced by a spatial growth rate when a coordinate assumes the role of evolution variable. Finally, the idea of spatial instability is applied to a Rayleigh-Bénard system given by a fluid-saturated horizontal porous layer with an anisotropic permeability and impermeable boundaries kept at different uniform temperatures.
Recombinant production of human antimicrobial peptide LL- 37 and its secondary structure

Published: October 2023

AbstractAntimicrobial peptides, including the human cathelicidin LL-37, offer a possible solution to the global problem of bacterial resistance to antibiotics. LL-37 peptide has potent antimicrobial effects against current multi-drug resistant bacterial strains. The peptide itself is also characterized by a very diverse range of immunomodulatory effects. The aim of this study was to produce antimicrobially active peptide LL-37 in E. coli in high yields using an own expression system pUbEx100 with the fusion protein ubiquitin. The results showed that the peptide GLL-37 could be produced in high amounts, but this peptide did not have antimicrobial activity compared to synthetically produced LL-37. CD spectroscopy results showed that the produced peptide GLL-37 is in α-helix form in contrast to the sLL-37 (random-coil form). The recombinant peptide GLL-37 can not bind to the membrane in the α-helix form, it would have to be in the form of a random-coil. This study confirms by CD spectroscopy the previously observed mechanism of access of LL-37 peptide to the bacterial membrane obtained by NMR.
Sternal sparing aortic valve replacement via right anterior minithoracotomy: An early experience
Authors: Chia Rong Hui , Joshi Pragnesh 
Published: October 2023

Abstract
Purpose
This study aims to evaluate the perioperative outcomes of aortic valve replacement (AVR) via right anterior minithoracotomy (RAT) during the learning curve.

Methods
It was a retrospective, observational, cohort study of patients who underwent RAT AVR from June 2015 to April 2022. Primary outcomes measured were 30-day morbidity and mortality.

Results
A total of 107 consecutive patients underwent elective RAT AVR. Our patients were mostly male (78.5%), elderly (mean 68.7 years), and obese (34.6%). A majority of the patients (93.5%) were of low operative risk. Median cross-clamp and bypass times were 95 and 123 minutes respectively. There was a statistically significant correlation between increase in number of cases and decrease in operative time. All patients had no paravalvular leak at discharge. There were no operative cardiovascular mortality or major morbidity including stroke, myocardial infarction, renal failure requiring dialysis, or vascular complication. No patient required intraoperative conversion to full sternotomy for completion of AVR.

Conclusion
Our study demonstrated that RAT AVR can be safely introduced. The learning curve required in performing RAT AVR can be safely negotiated through training, previous experience in minimally invasive surgery, careful patient selection including use of preoperative computed tomography of the aorta, and introduction of sutureless/rapid deployment valves.
Bicriteria fabrication scheduling of two-component jobs on a single machine
Authors: Li Yijie 
Published: October 2023

AbstractThis paper studies the bicriteria problem of non-preemptively scheduling n jobs, each of which is associated with a due date and comprises a standard and a specific component, on a single fabrication machine to minimize makespan and maximum lateness simultaneously. The specific components are processed individually and the standard components are grouped into batches for processing. A setup time is required before each batch of standard components is processed. A standard component is available (i.e., ready for delivery to the next production stage) only when the batch it belongs to is totally completed, whereas a specific component is available on completion of its processing. The completion time of a job is defined as the moment when both its two components have been processed and are available. An $$O(n^2\log n)$$

Short Communication: Lived experience perspectives on genetic testing for a rare eye disease
Authors: Tam Mallorie T. , Daboub Alonso , Lou Hayami , Robillard Julie M. 
Published: October 2023

AbstractThis qualitative study explored the motivators and barriers for genetic testing for individuals with aniridia. Semi-structured interviews were conducted with 8 participants. The main findings highlighted the complex and interrelated factors involved in the decision-making process, including family planning, learning about the specific pathogenic variant of the disease and having access to genetic testing. Benefits and potential risks of genetic testing for aniridia were also discussed. For participants, gaining knowledge about their condition was perceived as a benefit, while administrative issues and concerns around privacy were identified as risks. Increased access to quality information about genetic testing and to the service and associated resources are needed to better support people living with aniridia.

AbstractA growing number of companies are developing or using wearable sensor technologies that can monitor, analyse and transmit data from humans in real time that can be used by the sporting, biomedical and media industries. To explore this phenomenon, we describe and review two high-profile sporting events where innovations in wearable technologies were trialled: the Tokyo 2020 Summer Olympic Games (Tokyo 2020, Japan) and the 2022 adidas Road to Records (Germany). These two major sporting events were the first time academic and industry partners came together to implement real-time wearable solutions during major competition, to protect the health of athletes competing in hot and humid environments, as well as to better understand how these metrics can be used moving forwards. Despite the undoubted benefits of such wearables, there are well-founded concerns regarding their use including: (1) limited evidence quantifying the potential beneficial effects of analysing specific parameters, (2) the quality of hardware and provided data, (3) information overload, (4) data security and (5) exaggerated marketing claims. Employment and sporting rules and regulations also need to evolve to facilitate the use of wearable devices. There is also the potential to obtain real-time data that will oblige medical personnel to make crucial decisions around whether their athletes should continue competing or withdraw for health reasons. To protect athletes, the urgent need is to overcome these ethical/data protection concerns and develop wearable technologies that are backed by quality science. The fields of sport and exercise science and medicine provide an excellent platform to understand the impact of wearable sensors on performance, wellness, health, and disease.
A selection method of variable speed centrifugal pumps for maximum hydraulic efficiency
Authors: Fouda Yahia M. 
Published: October 2023

AbstractVariable speed pumps (VSPs) are more energy efficient compared to other flow control methods such as throttling control valves. However, their selection process is not straightforward because the pump characteristics should be optimised against the load profile of the flow system for maximum hydraulic efficiency. This paper presents a VSPs selection method based on generic mathematical models of centrifugal pumps efficiency, characteristics and similitude, which enables the extension of this method to other types of turbomachines. This selection method results in a nonlinear algebraic equation that is solved numerically to obtain a reference flow rate that maximises the pumping system hydraulic efficiency. This reference flow rate is subsequently used to obtain the pump characteristic curves at all operating pump speeds. The results show that this method is fast, accurate and reliable. Because the developed method uses generic pump models rather than specific models from manufacturers’ databases, it enables the integration of VSP selection process in early engineering design phases of pumping systems.
Tracing the Disparity Between Healthcare Policy–Based Infrastructure and Health Belief–Lead Practices: a Narrative Review on Indigenous Populations of India

Published: October 2023

AbstractMost Indian tribes have limited access to healthcare facilities and rely heavily on traditional healing practices. This narrative review aimed to identify the disparities in the implementation of healthcare services and in accessing and availing these services by the indigenous population in India. We also have tried to throw light on the plausibility in strengthening the efficiency and efficacy of the public health system, by utilizing the available resources to its maximum potential, so that there will be a measurable outcome in the health status of these populations in India, coherently with the relevant sustainable development goals (SDG). The evidence from published literatures supports the fact that the disparity exists in the health status of indigenous populations in India as compared to the general populations. It emphasizes the need to address the key determinants such as the lack of knowledge, traditional healing practices and poor utilization of healthcare services provided to them. Various factors such as accessibility to healthcare resources, traditional healing practices, lack of awareness regarding healthcare services and schemes provided by the government, insufficient data regarding their issues and challenges and cultural and language barriers worsen the health status of indigenous people. However, our review reiterates that a well-structured and sustainable policy with reframed infrastructure and administration of healthcare system might bring a positive change in the health status of indigenous population in India.
