Effect of Transport Noise on Kelvin–Helmholtz Instability
Authors: Flandoli Franco , Morlacchi Silvia , Papini Andrea 
Published: October 2023

AbstractThe effect of transport noise on a 2D fluid may depend on the space-scale of the noise. We investigate numerically the dissipation properties of very small-scale transport noise. As a test problem we consider the Kelvin-Helmholtz instability and we compare the inviscid case, the viscous one, both without noise, and the inviscid case perturbed by transport noise. We observe a partial similarity with the viscous case, namely a delay of the instability.
Toward a Stochastic Parameterization for Oceanic Deep Convection
Authors: Jamet Quentin , Mémin Etienne , Dumas Franck , Li Long , Garreau Pierre 
Published: October 2023

AbstractCurrent climate models are known to systematically overestimate the rate of deep water formation at high latitudes in response to too deep and too frequent deep convection events. We propose in this study to investigate a misrepresentation of deep convection in Hydrostatic Primitive Equation (HPE) ocean and climate models due to the lack of constraints on vertical dynamics. We discuss the potential of the Location Uncertainty (LU) stochastic representation of geophysical flow dynamics to help in the process of re-introducing some degree of non-hydrostatic physics in HPE models through a pressure correction method. We then test our ideas with idealized Large Eddy Simulations (LES) of buoyancy driven free convection with the CROCO modeling platform. Preliminary results at LES resolution exhibit a solution obtained with our Quasi-nonhydrostatic (Q-NH) model that tends toward the reference non-hydrostatic (NH) model. As compared to a pure hydrostatic setting, our Q-NH solution exhibits vertical convective plumes with larger horizontal structure, a better spatial organization and a reduced intensity of their associated vertical velocities. The simulated Mixed Layer Depth (MLD) deepening rate is however too slow in our Q-NH experiment as compared to the reference NH, a behaviour that opposes to that of hydrostatic experiments of producing too fast MLD deepening rate. These preliminary results are encouraging, and support future efforts in the direction of enriching coarse resolution, hydrostatic ocean and climate models with a stochastic representation of non-hydrostatic physics.
Correlated Structures in a Balanced Motion Interacting with an Internal Wave
Authors: Maingonnat Igor , Tissot Gilles , Lahaye Noé 
Published: October 2023

AbstractCharacterizing the loss of coherence of an internal tide propagating through mesoscale turbulence has been a major challenge in oceanography, particularly due to its implications for the interpretation of satellite data. In this paper, we intend to study the correlations between a balanced motion and the incoherent part of a wave in an idealised configuration. We introduce a new modal decomposition technique, named broad-band proper orthogonal decomposition (BBPOD), which consists in performing a proper orthogonal decomposition (POD) on complex demodulated variables. After connecting BBPOD to the standard SPOD, we show that BBPOD, coupled with the extended POD technique enables us to associate the principal components of the incoherent field to the slow flow structures responsible of this loss of coherence through triadic interactions with the incident wave.
Between Critical Inquiry and Creative Writing
Authors: Triandafyllidou Anna , Kumar Alka 
Published: October 2023

AbstractThis hybrid edited collection embodies the experience of living in liminal spaces, containing as it does between its covers, both academic essays grounded in critical inquiry as well story-chapters that employ a variety of creative writing genres. With potential to appeal to an academic reader and scholar of migration, its objective is also to be equally accessible to a more mainstream readership, particularly if they have a general interest in migration stories and issues. In addition to exploring some of the key trajectories and tropes that pertain to the migration experience, the volume also goes behind the scenes to tell the story of the workshopping process that the StOries Project journey was for its participants. One of its objectives is to show the reader how the project led to the birthing of the twenty creative writing chapters this volume contains.This edited volume then, emerged specifically from a fusion of scholarly inquiry and creative writing that participants (also its contributing authors) engaged with. In this first chapter, several key contexts, themes, and approaches that pertain to migration are discussed; significant related concepts are organised by the editors in thematic categories.Finally, in this introductory chapter, we also discuss recent developments in the respective migration trajectories, including identifying gaps in migration theory and methodology that we feel creative writing can contribute towards addressing. The significance of amplifying personal voices and unique stories is reiterated through sharing examples from the 20 stories collected in this volume.
For DYee… Walking in These Shoes
Authors: Hui Christian 
Published: October 2023

AbstractThis is Derek’s story, and I share this with you as I wear a pair of black suede shoes he had gifted me. Originally written to pay homage to my late dear friend, the creative writing process has also made the work a story of mine.As an immigrant settler, I have lived more than half of my life on Turtle Island on both the West Coast and the Eastern region of the North American continent. Reflecting on my identity, or rather identities, often rouses for me multiplicities of memories, emotions, lessons, and convictions. Am I a stranger to this land which I now live on, or have I always been a stranger to my own self? While my writing may never fully present all of my experiences, one realization I gained, both as an applied researcher in training and a racialized, queer, poz activist, is that our stories and truths deserve to be told.
Suitcases: A Story of Migration During the Pandemic
Authors: Kazmi Nabila 
Published: October 2023

AbstractAs 2020 happened, I decided to migrate from my homeland to a new and faraway country filled with prospects for the future. For somebody who fears flying, the longest flight of my life would be the easiest part of my journey. Little did I know that this journey of moving would encapsulate inflated moments of stillness. The story captures why I decided to make the journey and what it meant as I finally landed on the other side of the globe.This story captures the essence of a journey undertaken to a faraway land during a time when the world stood still. The journey was long and difficult yet filled with adventures of un/becoming.
Things Lost, Things Not Lost, and the Ones That Were Found on the Way
Authors: Javaher Negin Saheb 
Published: October 2023

AbstractA teenage girl’s journey of leaving her home in Iran to move to Canada with her family is shaped around a secret box of memories that needs to accompany the main character to her new home in Canada. The story focuses on themes of belonging, “home”, identity; and experiences of Iranian teenage women told through a simple tale of teenagehood in Iran. The teenage girl experiences an identity crisis that starts with the migration journey itself and as the family arrives in the Canadian airport for the very first time, new insights into their immigrant realities unfold.The story is called Things Lost, Things Not Lost, And the Ones That Were Found on The Way. It is a simple story of a family’s journey to Canada, and it begins when the family is leaving Tehran, ending when they arrive at Toronto’s Pearson International airport. Told in the voice of the family’s teenage daughter, it is a mix of imagination and experiences I personally have lived through. What I have tried to capture in this playful snapshot of a family’s journey are the feelings and emotions they experience before immigrating to a new country. These feelings of letting go are intertwined with meaningful pieces of identity and the journey is full of contradictions that mimic the paradoxes and the challenges immigrant families experience as they try to adapt to their new life, including changes in family dynamics and gender relations.
Immigrant Stories
Authors: da Costa Thabata 
Published: October 2023

AbstractThe migrant experience is above all a humbling one. There is often a wrong perception amongst those who live in places where migrants tend to go that the resilience we carry is due to some negative experiences we had where we came from; and that this justifies the hardships we endure in the places we choose to call home. The story is frequently very different. We move full of hopes and dreams, and many would not take the leap if conscious of all the barriers we are sure to face. The stories of migration are as diverse as the number of stars in the sky. And for that reason, the idea of migrants as a single group goes against any kind of reality if examined for more than a second. Although in Canada there are established categories of immigrants, such as economic migrants and refugees (and several others), within these categories are human journeys that are specific to each individual. Even inside a family we find different reasons for taking the leap. While one can choose to move away to have better professional opportunities, others might only be looking to get away from the mess their families are tangled in. To distance oneself from one’s birthplace can encompass the understanding that one’s comfort zone lies in a distant place, far away from social pressures – a chance to reinvent yourself as an individual.
Becoming Through Story: The Relational Processes of Writing and Creating the StOries Project
Authors: Damiano Natasha 
Published: October 2023

AbstractThis final chapter is not a typical recapitulation of the stories and ideas presented in this anthology. Rather it is a storied approach to reflecting on the relational processes of the StOries project, in order to contemplate what we have learned and to propose where we might go from here. I interweave my own reflections (and diffractions) of the challenges faced in writing this discussion of ‘fieldnotes’ that a number of authors submitted to describe their own writing processes. I also showcase examples of methods used in the project to illustrate how we generated meaningful introductions and discussions about identity, intersectionality, home, and belonging (among other things). Ideally the chapter will be read not as a conclusion, but as an opening to new ways of viewing ourselves and each other in the context of migration research. It also aims to promote the Indigenization of migration scholarship and the institutions that teach and create this scholarship, and to encourage discussions and changes in how we view people who migrate.
On Immigration, Religion and Home
Authors: Baksh Bibi 
Published: October 2023

AbstractRandom thoughts on immigration, religion, and home is a journey into the past that transpires with a trip to the country of my origin, Guyana, which I had left in 1982 to immigrate to Canada. In this story, I revisit the schools I attended as a child to reflect on how religion was intertwined with education in a colonised British state and used to exercise control over the people. On immigration, I draw on my grandfather’s transatlantic trip as an Indentured Servant from India; and I reflect on my own journey of immigration and belonging to Canada through the lens of my relationship with religion. My final stop in the story is my childhood home where I take time to consider the meaning of home that emerges from my heritage and personal experiences as a Muslim woman of Indian heritage, growing up in Guyana, and living my adult life in Canada.
My Journey as a Writer
Authors: Guo Owen 
Published: October 2023

AbstractIn this piece, I reflect upon my own writing journey, from being a reporter, a translator, and a researcher in the newsroom, to writing for a global audience about my country. Journalistic storytelling is impartial, often done with an emotional distance from the subjects caught up in a news event. During my journalism days, I was surrounded by exceptional writers and editors. It was, however, in Canada where my real writer identity was born. Through word building and writing of a different kind, I seek to understand my own place in a country I hope to one day call home.
Sphaleron in the Higgs Triplet Model
Authors: Hu Jiahang , Yu Bingrong , Zhou Shun 
Published: October 2023

Abstract
The Higgs triplet model (HTM) extends the Standard Model (SM) by one complex triplet scalar (also known as the type-II seesaw model), offering a simple and viable way to account for nonzero neutrino masses. On the other hand, the nontrivial couplings of the triplet to the gauge fields and to the SM Higgs field are expected to influence the topological vacuum structure of the SM, and consequently, the energy and the field configuration of the electroweak sphaleron. The sphaleron process plays a crucial role in dynamically generating the baryon asymmetry of the Universe. In this work, we study the vacuum structure of the gauge and Higgs fields and calculate the saddle-point sphaleron configuration in the HTM. The coupled nonlinear equations of motion of the sphaleron are solved using the spectral method. We find the inclusion of the triplet scalar could in principle significantly change the sphaleron energy compared with the SM. Nevertheless, at zero temperature, the current stringent experimental constraint on the vacuum expectation value of the triplet suppresses the difference. Interestingly, we find that there still exists some narrow parameter space where the sphaleron energy can be enhanced up to 30% compared with the SM case.

Functional alignment in total knee arthroplasty best achieves balanced gaps and minimal bone resections: an analysis comparing mechanical, kinematic and functional alignment strategies
Authors: Van de Graaf Victor A. , Chen Darren B. , Allom Richard J. , Wood Jil A. , MacDessi Samuel J. 
Published: October 2023

AbstractPurposeKey concepts in total knee arthroplasty include restoration of limb alignment and soft‐tissue balance. Although differences in balance have been reported amongst mechanical alignment (MA), kinematic alignment (KA) and functional alignment (FA) techniques, it remains unclear whether there are differences in gap imbalance or resection thicknesses when comparing different constitutional alignment subgroups.MethodsMA (measured resection technique), KA (matched resections technique) and FA (technique based on the restricted KA boundaries) were compared in 116 consecutive patients undergoing 137 robotic‐assisted cruciate‐retaining total knee arthroplasties. The primary outcome was the proportion of balanced gaps (differential laxities ≤ 2 mm) for extension, flexion, medial and lateral gap measurements. Manual pre‐resection laxity measurements were obtained for MA and KA and manual post‐resection measurements were obtained for FA in 10° and in 90° of knee flexion. Secondary outcomes were resection depths and implant alignment. All outcomes were analysed per constitutional coronal alignment and joint line obliquity subgroups.ResultsThe proportions of balance in all four gap measurements were 54.7%, 66.4% and 96.5%, with MA, KA and FA, respectively. Across all constitutional alignment types, FA achieved the highest proportion of balance. MA resected the least amount of bone from the medial tibial plateau. KA had femoral components in most valgus and most internally rotated, tibial components in most varus and was the most bone‐preserving for the posteromedial femoral condyle. FA had the most externally rotated femoral components and was most bone‐preserving for the distal femoral resections.ConclusionThe study shows that implant alignment to the mechanical axis or joint line anatomy (equal resections) alone does not guarantee a balanced total knee arthroplasty. FA resulted in the highest proportion of balanced knees across all analysed subgroups. Future research will consider whether one alignment philosophy leads to superior outcomes for different constitutional alignment subgroups.Level of evidenceLevel II.
Exercise‐induced fatigue affects knee proprioceptive acuity and quadriceps neuromuscular function more in patients with ACL reconstruction or meniscus surgery than in healthy individuals
Authors: Kim Sungwan , Glaviano Neal R. , Park Jihong 
Published: October 2023

AbstractPurposeTo observe how knee proprioceptive acuity and quadriceps neuromuscular function change during and after repeated isokinetic knee‐extension exercise in patients with anterior cruciate ligament reconstruction (ACLR) or meniscus surgery.MethodsPatients with ACLR or meniscus surgery and matched controls (n = 19 in each group) performed knee‐flexion replication at 15° and 75°, and quadriceps peak torque (PT), central activation ratio (CAR) and rate of torque development (RTD) at baseline and immediately after every five sets of isokinetic knee‐extension exercise (times 1–5).ResultsCompared to the baseline, the ACLR and control groups displayed errors in knee‐flexion replication at 75° only at time 5 (115.9–155.6%; p ≤ 0.04, d ≥ 0.97), whereas the meniscus surgery group exhibited errors at all time points (142.5–265.6%; p ≤ 0.0003, d ≥ 1.4). Significant percentage reductions in quadriceps CAR were observed between times 4 and 5 in the ACLR group (–5.8%; p = 0.0002, d = 0.96), but not in the meniscus surgery (–1.4%; n.s.) and control (0.1%; n.s.) groups. Significant percentage reductions in quadriceps RTD were observed between times 4 and 5 in the ACLR (–24.2%; p = 0.007, d = 0.99) and meniscus surgery (–23.0%; p = 0.01, d = 0.85) groups, but not in the control group (–0.2%; n.s.).ConclusionPatients with ACLR or meniscus surgery displayed a greater loss in knee proprioceptive acuity and quadriceps neuromuscular function during and after exercise than healthy individuals. Evidence‐based interventions to enhance exercise‐induced fatigue resistance should be implemented following ACLR or meniscus surgery, aiming to prevent proprioceptive and neuromuscular changes within the knee joint and quadriceps.Level of evidenceIII.
Spectroscopy from quantum dynamics: a mixed wave function/analytical line shape functions approach
Authors: Montorsi Francesco , Aranda Daniel , Garavelli Marco , Santoro Fabrizio , Segatta Francesco 
Published: October 2023

AbstractQuantum dynamics is the natural framework in which accurate simulation of spectroscopy of nonadiabatically coupled molecular systems can be obtained. Even if efficient quantum dynamics approaches have been developed, the number of degrees of freedom that need to be considered in realistic systems is typically too high to explicitly account for all of them. Moreover, in open-quantum systems, a quasi-continuum of low-frequency environment modes need to be included to get a proper description of the spectral bands. Here, we describe an approach to account for a large number of modes, based on their partitioning into two sets: a set of dynamically relevant modes (so-called active modes) that are treated explicitly in quantum dynamics, and a set of modes that are only spectroscopically relevant (so-called spectator modes), treated via analytical line shape functions. Linear and nonlinear spectroscopy for a realistic model system is simulated, providing a clear framework and domain of applicability in which the introduced approach is exact, and assessing the error introduced when such a partitioning is only approximate.
On the atomic structure of torsion-free monoids
Authors: Gotti Felix , Vulakh Joseph 
Published: October 2023

AbstractLet M be a cancellative and commutative (additive) monoid. The monoid M is atomic if every non-invertible element can be written as a sum of irreducible elements, which are also called atoms. Also, M satisfies the ascending chain condition on principal ideals (ACCP) if every increasing sequence of principal ideals (under inclusion) becomes constant from one point on. In the first part of this paper, we characterize torsion-free monoids that satisfy the ACCP as those torsion-free monoids whose submonoids are all atomic. A submonoid of the nonnegative cone of a totally ordered abelian group is often called a positive monoid. Every positive monoid is clearly torsion-free. In the second part of this paper, we study the atomic structure of certain classes of positive monoids.
The electrical restitution of the non-propagated cardiac ventricular action potential
Authors: Zaniboni Massimiliano 
Published: October 2023

AbstractSudden changes in pacing cycle length are frequently associated with repolarization abnormalities initiating cardiac arrhythmias, and physiologists have long been interested in measuring the likelihood of these events before their manifestation. A marker of repolarization stability has been found in the electrical restitution (ER), the response of the ventricular action potential duration to a pre- or post-mature stimulation, graphically represented by the so-called ER curve. According to the restitution hypothesis (ERH), the slope of this curve provides a quantitative discrimination between stable repolarization and proneness to arrhythmias. ER has been studied at the body surface, whole organ, and tissue level, and ERH has soon become a key reference point in theoretical, clinical, and pharmacological studies concerning arrhythmia development, and, despite criticisms, it is still widely adopted. The ionic mechanism of ER and cellular applications of ERH are covered in the present review. The main criticism on ERH concerns its dependence from the way ER is measured. Over the years, in fact, several different experimental protocols have been established to measure ER, which are also described in this article. In reviewing the state-of-the art on cardiac cellular ER, I have introduced a notation specifying protocols and graphical representations, with the aim of unifying a sometime confusing nomenclature, and providing a physiological tool, better defined in its scope and limitations, to meet the growing expectations of clinical and pharmacological research.
