description: Welding is an important manufacturing process used in various industries, from automotive to aerospace. However, existing welding techniques have certain drawbacks that affect weld integrity and limit their use in joining some temperature-sensitive materials. A significant concern is the heat-affected zone (HAZ), which often becomes softer than its surrounding areas. To address this problem, the expansion of cold spray process—a solid-state layer-by-layer high speed particle deposition process—as an alternative solid-state welding technique is proposed, developed, and evaluated, a process referred to as cold spray welding (CSW). As a starting point, the origin of softening in a Tungsten inert gas (TIG)-welded AA 6061-T651 plates is first comprehensively investigated using experimental, analytical, and thermodynamic modelling approaches; this is further compared with the CSWed samples to assess its (CSW) potential and current limitations for future optimization. The outcome of this study reveals that the softening effect or HAZ in the TIG-welded sample could extend up to ~40 mm from the weld center. The HAZ further partitions into four regions: HAZ1, HAZ2, HAZ3, and HAZ4, based on peak temperature, hardness, and stable precipitate phases in those regions. While the CSWed samples show several benefits: negligible microstructural alterations, inhibition of phase transformations, and suppression of deleterious HAZ, they exhibit lower tensile strength and impact toughness than TIG-welded counterpart due to the presence of ubiquitous microvoids resulting from inadequate metallurgical bonding in CSWed area. These microvoids act as initiation sites for microcracks. To guide future optimization efforts, a failure mechanism in the CSWed parts is established. This research underscores the importance of addressing softening effects in welded materials, while also charting a new path to establishing a new unexplored solid-state welding technique that has the potential to minimize the drawbacks in conventional welding methods. By understanding and overcoming the poor particle-particle/particle-substrate metallurgical bonding, CSW is poised to be an alternative greener solid-state welding technique for applications in various industries.

description: LHC searches for the standard model Higgs Boson in WW or ZZ decay modes place strong constraints on the top-Higgs state predicted in many models with new dynamics preferentially affecting top quarks. Such a state couples strongly to top-quarks, and is therefore produced through gluon fusion at a rate enhanced relative to the rate for the standard model Higgs boson. A top-Higgs state with mass less than 300 GeV is excluded at 95% CL if the associated top-pion has a mass of 150 GeV, and the constraint is even stronger if the mass of the top-pion state exceeds the top-quark mass or if the top-pion decay constant is a substantial fraction of the weak scale. These results have significant implications for theories with strong top dynamics, such as topcolor-assisted technicolor, top-seesaw models, and certain Higgsless models.

Exercise-induced arterial hypoxemia in healthy young women; role of mechanical constraints to ventilation
Creators: name: Dominelli, Paolo Biagio
Publisher: name: University of British Columbia
Year: 2012

description: Many young adult male athletes with a high maximal O₂ consumption (VO₂Max) show exercise-induced arterial hypoxemia (EIAH). In women, EIAH may occur at submaximal exercise intensities and at lower fitness levels, but this is controversial. Greater EIAH in women may be attributed to their increased mechanical constraints to ventilation owing to smaller airway diameters. Accordingly, the purpose of this study was to characterize EIAH, gas exchange and respiratory mechanics during exercise in young healthy women. Subjects (n=31, VO₂Max =48±1, range 28-62 mL/kg/min) completed a step-wise maximal test on a treadmill. A 3-stage constant load exercise test was also completed where the inspired gas was switched between room air and heliox (21% O₂: 79% He). Arterial blood gases (PaO₂, PaCO₂, pH), corrected for esophageal temperature, and oxyhemoglobin saturation (SaO₂) were measured at rest and during the last 30 s of each exercise stage. The work of breathing (WOB) was obtained using an esophageal balloon-tipped catheter. Expiratory flow limitation (EFL) was determined by superimposing tidal flow-volume loops on the maximum expiratory flow-volume curve. Twenty of the 31 women developed some degree of EIAH with a nadir PaO₂ and SaO₂ ranging from 58-103 mmHg and 87-98%; respectively. Subjects with EIAH were fitter (VO₂Max 51±1 vs. 42±2 mL/kg/min), had a greater VEMax (91±3 vs. 77±4 L/min) and had an increased resistive WOB (30±2 vs. 19±1 cmH₂O/breath); for the EIAH and non-EIAH groups respectively (P<0.05). Six untrained subjects (VO₂Max <50 mL/kg/min) developed EIAH and 18/20 of the EIAH group were hypoxemia at submaximal intensities. Six distinct patterns of hypoxemia were observed indicating multiple mechanisms are responsible for EIAH in women. Fourteen subjects developed EFL and 12/14 who showed flow limitation also displayed EIAH. Inspiring heliox gas decreased the WOB by ~32% and partially reversed any EIAH. In conclusion, the pulmonary system response to progressive treadmill exercise in healthy young women is variable and distinct patterns of EIAH exist. EIAH appears to start at submaximal intensities and untrained women can develop hypoxemia. Mechanical ventilatory constraints can lead to or exacerbate EIAH in women, while inspiring heliox gas can partially reverse EIAH.

description: Kinetic gait analysis of subacute stroke is a relatively unexplored area of study. Chronic stroke literature on the subject is extensive but does not capture the time period where the extent of recovery is greatest. Translating methods of gait analysis seen in research to a clinical setting is subject to many additional requirements which have previously prevented such investigations. The work presented in this thesis represents the first investigation using NeuroRecoVR, a new instrumented treadmill facility located within an inpatient rehabilitation gym. Working directly with inpatient physiotherapists, this study examines kinetic based gait parameters to quantify levels of impairment in subacute stroke. Recovery is most readily seen in changes in the walking speed of an individual, with many other gait parameters changing alongside walking speed. Therefor the relationships for all parameters of interest to walking speed are investigated in both neurologically intact controls (n = 14) and those undergoing rehabilitation for subacute stroke (n = 15). Parameters including spatiotemporal measures, forces, impulses, center of mass trajectory, center of pressure variability, and measures of symmetry were calculated for both groups. Subacute stroke participants have higher levels of asymmetry, increased instability, and altered gait dynamics compared to neurologically intact controls. The extent of recovery for each parameter was examined in a subset of stroke patients who took part in instrumented treadmill training over 1-2 months of rehabilitation (n = 4; mean ±SD age = 65 ±17; mean ±SD days post stroke at first session = 79 ±67). These participants showed improvements in stability, walking speed, and symmetry over the course of rehabilitation. These results show the benefit and potential for the use of kinetic analysis for aspects of both research and rehabilitation

description: We present FlavourFrame, a canvas-based app that helps tasters capture and visualize their perceptions during mindful tasting experiences. Taste perceptions are difficult to document because they are subjective, multisensory, and ephemeral; and everyday people have limited dedicated vocabulary to describe such experiences. Our customizable tool is designed to help novice and experienced tasters structure and record tasting experiences. FlavourFrame superimposes visual and text layers to personalize visual and word- based expression of flavour experience. Through autoethnographic reflections, we generated sample data and identified strengths and limitations of the prototype.

description: The zero-range process is a stochastic interacting particle system that exhibits a condensation transition under certain conditions on the dynamics. It has recently been found that a small perturbation of a generic class of jump rates leads to a drastic change of the phase diagram and prevents condensation in an extended parameter range. We complement this study with rigorous results on a finite critical density and quenched free energy in the thermodynamic limit, as well as quantitative heuristic results for small and large noise which are supported by detailed simulation data. While our new results support the initial findings, they also shed new light on the actual (limited) relevance in large finite systems, which we discuss via fundamental diagrams obtained from exact numerics for finite systems.

description: By extending the methods used in our earlier work, in this paper, we present an explicit realization of logarithmic $\mathcal{W}_{p,p'$}-modules that have L(0) nilpotent rank three. This was achieved by combining the techniques developed in \cite{AdM-2009} with the theory of local systems of vertex operators \cite{LL}. In addition, we also construct a new type of extension of $\mathcal{W}_{p,p'}$, denoted by $\mathcal{V}$. Our results confirm several claims in the physics literature regarding the structure of projective covers of certain irreducible representations in the principal block. This approach can be applied to other models defined via a pair screenings.

description: FluencyAR is an augmented reality second language learning tool centered around the concepts of language immersion and self-talk. For many second language learners, advancing into upper levels of fluency can be difficult without sufficient opportunities to practice. Traditional solutions of tutoring or finding exchange partners are often inconvenient or limiting. FluencyAR provides situational conversation practice in highly self-directed practice sessions that imitate environments where the target language is dominant. We utilize augmented reality to allow users to practice their target language with immediate feedback at any time, and from any location. Using ChatGPT and the physical space of the user, we can produce unique and challenging conversation prompts relative to a user’s surroundings, ensuring that sessions remain interesting.

description: Background: Preterm birth (PTB) is defined as a live birth before 37 weeks of gestation and remains a major public health concern, affecting an estimated 15 million births annually with a global prevalence of 11%. Socioeconomic disparities play a crucial role in PTB rates, with both individual- and neighborhood-level factors contributing. Stress response pathway has been identified as a key mechanism in the relationship between neighborhood socioeconomic status (nSES) and PTB risk. As such, the new challenges added due to the COVID-19 pandemic, such as disruption to the support networks and increased psychosocial distress for pregnant individuals, were expected to increase PTB rates. However, studies found lack of change or even decrease in the incidence during this period. It is suggested that such counter intuitive findings are due to lack of consideration for the differential exposure to the pandemic-related hardships based on nSES. Therefore, the primary aim of the present study is to test whether a measure of objective pandemic hardship and psychological distress mediate the relationship between nSES and PTB. Methods: Present study is a secondary analysis of the data collected from a prospective longitudinal cohort study, Pregnancy during the Pandemic (PdP). Two serial mediation path models with a measure of baseline objective pandemic hardship and psychological distress included as mediators between nSES and PTB/gestational age (GA) were tested. Results: In both models, the main indirect pathway of interest from nSES to pandemic objective hardship, psychological distress, then PTB/GA was non-significant with minimal effect. Secondary indirect pathway of interest from pandemic objective hardship to psychological distress then PTB/GA was significant in both models while controlling for months into the pandemic at birth and baseline sociodemographic characteristics. Discussion: The present paper is the first to test a comprehensive model of the role of nSES on PTB risk with an explicit measure of pandemic objective hardship and psychological distress included as mediators. While the main indirect serial mediation pathway was non-significant, partial support for the proposed mechanism was observed where increase in pandemic-related hardship elevated psychological distress, which then heightened the risk of PTB risk and shortened gestational age at birth.

description: Depression is a highly prevalent mood disorder, especially during adolescence and early adulthood. It is commonly treated with antidepressants; however, one-third of patients with depression do not respond to current therapies. Interestingly, it has been found that depression severity is correlated with zinc deficiency, and zinc supplements can improve individuals’ depressive symptoms, potentially through its actions as a neurotransmitter. This phenomenon is facilitated by zinc transporter 3 (ZnT3), which packages zinc into synaptic vesicles. Using a ZnT3 knockout (KO) mouse model that lacks vesicular zinc, we sought to investigate the interplay between vesicular zinc and chronic stress, as well as ketamine, a novel therapeutic for treatment-resistant depression, which has been shown to display rapid and sustained antidepressant-like effects. Wildtype (WT) and ZnT3 KO mice were subjected to multiple simultaneous acute stress (MAS) or kept under standard housing conditions during late adolescence, and subsequently administered ketamine (10 mg/kg) or 0.9% saline. The lack of vesicular zinc in ZnT3 KO mice differentially altered the effects of MAS in behaviours related to anxiety, motivation/apathy, and passive coping, but not anhedonia, in a sex-dependent manner. These data suggest that vesicular zinc modulates stress response. Vesicular zinc, however, did not impact the effects of MAS on neuronal morphology. Moreover, we found limited effects of ketamine in depressive-like behaviours and neuronal structure, but intriguingly, ketamine appeared to compensate for the lack of vesicular zinc in ZnT3 KO mice. Collectively, these findings support that chronic stress impacts behaviour differently in WT and ZnT3 KO mice. However, the single subanaesthetic dose of ketamine administered was not sufficient to alter responses to stress. Further inquiry is warranted to elucidate the combined effect of vesicular zinc and ketamine in stress response.
OPERA superluminal neutrinos and Kinematics in Finsler spacetime

description: The OPERA collaboration recently reported that muon neutrinos could be superluminal. More recently, Cohen and Glashow pointed that such superluminal neutrinos would be suppressed since they lose their energies rapidly via bremsstrahlung. In this Letter, we propose that Finslerian nature of spacetime could account for the superluminal phenomena of particles. The Finsler spacetime permits the existence of superluminal behavior of particles while the casuality still holds. A new dispersion relation is obtained in a class of Finsler spacetime. It is shown that the superluminal speed is linearly dependent on the energy per unit mass of the particle. We find that such a superluminal speed formula is consistent with data of OPERA, MINOS and Fermilab-1979 neutrino experiments as well as observations on neutrinos from SN1987a.

description: Most holographic models of superconducting systems neglect the effects of dynamical boundary gauge fields during the process of spontaneous symmetry-breaking. Usually a global symmetry gets broken. This yields a superfluid, which then is gauged "weakly" afterwards. In this work we build (and probe the dynamics of) a holographic model in which a local boundary symmetry is spontaneously broken instead. We compute two-point functions of dynamical non-Abelian gauge fields in the normal and in the broken phase, and find non-trivial gapless modes. Our AdS3 gravity dual realizes a p-wave superconductor in (1+1) dimensions. The ground state of this model also breaks (1+1)-dimensional parity spontaneously, while the Hamiltonian is parity-invariant. We discuss possible implications of our results for a wider class of holographic liquids.

description: One of the primary objectives of structural design optimization is to achieve a design possessing the lowest possible weight, while it can safely withstand the effects of external loads. In the case of a truss of a specific topology, the role of an optimization algorithm is to determine the configuration and number of the truss elements as well as their cross-sectional areas. In this study, a novel model is proposed, by which the main optimization problem is decomposed into two more manageable problems: a size optimization within a shape optimization problem. A Deep Neural Network (DNN) is trained to approximate the optimal cross-sectional areas of the elements of a truss with a given shape and support positions. Furthermore, truss structures are characterized by pin joints connected by truss members, a concept that can be analogized to vertices and edges in a mathematical graph. Leveraging this analogy, a Graph Neural Network (GNN) is utilized to exploit the advantages of representing trusses as graphs. Specifically, a graph neural network-based surrogate model integrated with Particle Swarm Optimization (PSO) algorithm is developed to approximate nodal displacements of trusses during the design optimization process. Several truss examples are used to investigate the validity and effectiveness of the proposed optimization techniques in comparison with conventional FEM-based models.

description: We analyze the generation of polarization cross-talk in Stokes polarimeters by atmospheric seeing, and its effects on the noise statistics of spectropolarimetric measurements for both single-beam and dual-beam instruments. We investigate the time evolution of seeing-induced correlations between different states of one modulation cycle, and compare the response to these correlations of two popular polarization modulation schemes in a dual-beam system. Extension of the formalism to encompass an arbitrary number of modulation cycles enables us to compare our results with earlier work. Even though we discuss examples pertinent to solar physics, the general treatment of the subject and its fundamental results might be useful to a wider community.

description: Electromechanics is the field of studying the interaction between microwave resonators and mechanical oscillators. It has been an interesting topic in the recent decade due to its numerous potential applications in science and technology, including ground-state cooling of macroscopic objects, quantum sensing, quantum memory, and quantum transduction. This thesis presents a comprehensive analysis of a project focused on simulating, designing, and modeling electromechanical devices with the ultimate objective of achieving their successful implementation. Through the thesis, after an overview of the theoretical model of electromechanics, I will introduce our design for the device and explain how we simulated it to optimize its characteristics. Next, I will discuss the nanofabrication process we have developed for the device, along with the fundamental aspects of the characterization method and setup. Subsequently, I will present the theoretical model I have developed based on electromechanics. This model has significant potential to open up new avenues for future research, building upon the foundation laid by the current project.

description: In 2018, the Research Data Management Services of Leibniz University Hannover, Germany, conducted a self-assessment using the “Research Infrastructure Self Evaluation Framework” (RISE) published by the British Digital Curation Centre. The main objective of the self-assessment was to gauge current achievements and to determine the fields in which further development is required in order to update road map documents. Another aim was to test the applicability of “RISE” in a German context.

The Lightning Talk "Using RISE for Service Evaluation - Experiences, Findings and Differences" reflects the experiences and results of the self-assessment at Leibniz University Hannover.  Furthermore, it proposes an "Embedded Research Data Management Service Model" to integrate the organisational embedding of Research Data Managament Services in the RISE-Framework.

The Lightning Talk carries important insights for the development of Research Data Management Services, which is an issue that becomes more and more important in higher education institutions (HEIs) all over the world.

description: This work builds on a multi-year community outreach platform led by the Indigenous, Local and Global Health Office at the University of Calgary’s Cumming School of Medicine, to investigate how sport may be supportive of wellness in Indigenous youth. It builds on literature that has shown the promise of sport as a population-level approach for promoting wellness among youth. For this qualitative study, we interviewed eight Indigenous individuals involved in sport, either in their youth or in a leadership capacity as an adult, asking: how do sports support Indigenous youth wellness? Two rounds of iterative thematic analysis were conducted, first investigating how participants described wellness, then assessing how sport acted to promote their concepts of wellness. Participants described the concept of wellness through four core components: i) belonging to something greater than yourself, ii) developing identity, iii) overcoming adversity, and iv) belonging and contributing to a community of support. In investigating how sport supports wellness, one major theme emerged that crosscut all others: connectedness. This manifested at the personal, interpersonal, and wider social levels in the lives of participants. This work culminates in considering how existing frameworks for youth wellbeing can be expanded to better include Indigenous perspectives. Findings are oriented to policy action in the Cumming School of Medicine, as well as aim to influence change of practice for those working with Indigenous youth in sport more broadly.

description: A precision measurement of the gamma yields following the beta decay of 32Cl has determined its isobaric analogue branch to be (22.47^{+0.21}_{-0.19})%. Since it is an almost pure Fermi decay, we can also determine the amount of isospin-symmetry breaking in this superallowed transition. We find a very large value, delta_C=5.3(9)%, in agreement with a shell-model calculation. This result sets a benchmark for isospin-symmetry-breaking calculations and lends support for similarly-calculated, yet smaller, corrections that are currently applied to 0+ -> 0+ transitions for tests of the Standard Model.

description: Multiparameter full waveform inversion (FWI) is a promising technique to estimate the elastic properties of the subsurface, but it is commonly affected by crosstalk between parameters of different nature, which impacts the convergence of the local optimization algorithms and introduces artifacts and uncertainty to the results. Hence, reducing these effects is essential to increase confidence in the estimates. This thesis is focused on proposing strategies to treat these artifacts in the model space of the density (ρ), P-wave velocity (Vp), and S-wave velocity (Vs) while considering seismic surface experiments. The crosstalk effects are described and corrected by the Hessian operator, which also affects the shape of the iso-surfaces of the objective function. Therefore, two methodologies were developed based on performing constrained re-parameterizations, aiming to find an intermediate model space with decorrelated parameter classes, i.e., where the Hessian is the identity matrix, to reach convergence to an accurate minimum point, and later transform it into the original model space. The difference between both strategies lies in the type and size of the Hessian matrix used, i.e., point-wise Hessians and point-probes Hessians, as well as in the numerical approach employed to compute the transformation matrices necessary to map between model spaces. In both strategies, the estimates of Vs were relatively accurate but the results of Vp and ρ were strongly impacted by crosstalk effects in comparison to those obtained with FWI approaches that were not re-parameterized; thus, the sought intermediate model space was not properly mapped. The decorrelation ideas were successful in certain aspects, but the challenges were related to the limitations brought by the amount of crosstalk information considered through the Hessians, the selected numerical approaches, and the type of transformation matrix computed, which was able to do a good job in some locations of the model grid or for some parameter classes, but was not general enough to produce the expected transformation in a large scale.

description: We apply the hydrodynamic model for the dynamics of matter created in p-Pb collisions at 4.4TeV and d-Pb collisions at 3.11TeV. The fluctuating initial conditions are calculated in the Glauber Monte-Carlo model for several centrality classes. The expansion is performed event by event in 3+1-dimensional viscous hydrodynamics. Noticeable elliptic and triangular flows appear in the distributions of produced particles.

description: "Though we see the same world we see it through different eyes" Virginia Woolf, Three Guineas This research and creation exposes how some social inequalities and machinations in society affect my performance of femininity. In this thesis support paper I reveal some foundational moments in my life as a cis gendered woman, that were directly and indirectly affected by a patriarchal logic. Through these experiences, I learned to adapt by modifying how I am seen; I perform my femininity as I have been directed. In this support paper, the theory behind The Gaze is used to decode what it feels like to be seen through a hegemonic male perspective, and then how this surveillance is used to construct societal and cultural foundations that I, and many women are expected to follow. My research responds to this by exploring visual strategies within a contemporary aesthetic, that elucidate and challenge how being seen is experienced. I examine significant moments in my life, that can be representative of many women, that were affected by the gaze of another and which influenced and then developed into a gaze of my own. This research looks at why this happens, and the outcome of when a lens turns inward. My artwork is structured through generative investigations that include case studies of contemporary feminist artists, feminist theory, literature review, and studio creation/installation, to develop a broader and deeper understanding of the underlying relationship between patriarchy and cultural phenomena that affect women. Through this research, there is an attempt to go beyond simply a critique of existing conditions and instead construct an autonomy from the male gaze structured through my self-realization as a woman.

description: We present a theoretical and numerical analysis of a quantum system that is capable of functioning as a heat engine. This system could be realized experimentally using cold bosonic atoms confined to a double well potential that is created by splitting a harmonic trap with a focused laser. The system shows thermalization, and can model a reversible heat engine cycle. This is the first demonstration of the operation of a heat engine with a finite quantum heat bath.

description: Investigating weakly bound complexes can provide insights into the nature of intermolecular interactions. Understanding the nature of these interactions are important as they play a crucial role in various physical, chemical and biological processes. Vinyl fluoride, 1,1-difluoroethylene and N2O are industrially important molecules. Anthropogenic emission makes these gases adequately abundant in atmosphere. Therefore, recognizing their complexation properties are vital to industrial and atmospheric chemistry. By studying the infrared spectra of these weakly bound complexes, we can gain a better understanding of their structure and stability. The work outlined in this thesis analyses the results obtained for vinyl fluoride-N2O (C2H3F-N2O) and 1,1-difluoroethylene-N2O (C2H2F2-N2O) dimers. Infrared spectra for fundamental bands of C2H3F-N2O and C2H2F2-N2O dimers were recorded in the ν3 asymmetric stretching region of N2O (~ 2223 cm-1). These weakly bound dimers were formed in a supersonic jet expansion apparatus and probed using a tunable external cavity quantum laser setup (EC-QCL). The van der Waals dimers observed have top bonded planar structures, similar results were obtained for their CO2 bonded counter parts. Geometry optimizations for these N2O bonded dimers were carried out at MP2 level of theory in conjunction with 6-311++G(2d,2p) basis set. The binding energy calculations were performed at the same level of theory and corrected for BSSE and ZPE. The experimental rotational constants are in agreement with the ab initio calculated values. However, the experimental evidence contradicts the predicted theoretical stability order. Similar results were found for their CO2 bonded counterparts. More experimental studies on N2O and CO2 bonded isomers of these dimers and ab initio calculations at a higher level of theory are required to address the discrepancies between the experimental findings and the stability order.

description: We consider the phenomenological consequences of fixing compactification moduli. In the simplest KKLT constructions, stabilization of internal dimensions is rather soft: weak scale masses for moduli are generated, and are of order m_σ~ m_{3/2}. As a consequence one obtains a pattern of soft supersymmetry breaking masses found in gravity and/or anomaly mediated supersymmetry breaking (AMSB) models. These models may lead to destabilization of internal dimensions in the early universe, unless the Hubble constant during inflation is very small. Fortunately, strong stabilization of compactified dimensions can be achieved by a proper choice of the superpotential (e.g in the KL model with a racetrack superpotential). This allows for a solution of the cosmological moduli problem and for a successful implementation of inflation in supergravity. We show that strong moduli stabilization leads a very distinct pattern of soft supersymmetry breaking masses. In general, we find that soft scalar masses remain of order the gravitino mass, while gaugino masses nearly vanish at the tree level, i.e. they are of order m_{3/2}^2/m_σ. Radiative corrections generate contributions to gaugino masses reminiscent of AMSB models and a decoupled spectrum of scalars reminiscent of split-supersymmetry. This requires a relatively large gravitino mass ~ O(100) TeV, resolving the cosmological gravitino problem and problems with tachyonic staus in AMSB models.

description: We study the synchronization properties of an array of non identical globally coupled limit cycle oscillators. Above a critical coupling strength, some oscillators undergo a selfpulsing instability. We study analytically the synchronization conditions below and above this instability threshold, thus removing the usual restriction of limit cycle stability. Selfpulsing decreases the order parameter and synchronization degradation can be reduced by delaying the coupling among the oscillators. Semiconductor lasers coupled by an external mirror are used as a convenient realization of that model.
