Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Design management

description: This thesis investigates factors which promote design management success and considers how design management capabilities in businesses and organisations can be assessed. The investigation is based on explorationand identification of important factors forthe successful use of design management. A review of the literature confirms the assimilation between the design processand NPD process success factorresearch, resulting in the development of the concept design management. A comprehensive list of the nine most frequently referenced NPD process success factors is derived from 64 research studies. A contextual review confirms the validity of the Design Management Staircase Model, the only known model to evaluate design management capabilities. The validity of the nine factors for promoting design management success is analysed based on a dataset gathered through the Design Management Europe (DME) Award. This validity is confirmed through an analysis of qualitative data gathered with DME Award entrants. The third part of the analysis builds the basis for a comparison between the Design Management Staircase Model and the NPD process success factors. This investigation provides insight into the design management capabilities of companies, identifying which factors are of greatest importance for design management capability assessment. Further, the analysis demonstrates that a complete process more important than any single factor. The PhD contributes to new knowledge regarding the importance of design managementto business resourcing, a meta-analysis that reveals the nine most important factors for design management, the importance of a process driven ABSTRACT approach to factor implementation, and a set of recommendations for the development of an improved design management capability assessment model.The underlying message of the results in this PhD thesis is that successful design managementcapabilities are highly dependent on the right expertise and building a complete process which consists of nine success factors.

description: Lead vanadate PbVO3 is a polar crystal with a P4mm space group at ambient conditions. It is isostructural with the model soft-mode driven ferroelectric PbTiO3, but differs from it by the so-called 'supertetragonal' elongation of its unit cell. In this paper, we report a combined study of the lattice dynamics of PbVO3 by Raman spectroscopy at room temperature and first-principle calculations. All zone-center transverse optical (TO) phonon modes are identified by polarized, angle-dependent Raman spectroscopy and assigned as follows: E modes at 136, 269, 374 and 508 cm-1, A1 modes at 188, 429 and 874 cm-1 and B1 mode at 319 cm-1. The calculations confirm the experimental symmetry assignment and allow to obtain the longitudinal (LO) phonons wavenumbers. Besides, we analyze the mode eigenvectors in detail, in order to identify the atomic displacements associated with each mode and compare them with PbTiO3. In spite of their differences in chemistry and strain, the phonon eigenvectors are found to be remarkably comparable in both compounds. We discuss the position of the ferroelectric soft mode in PbVO3 as compared to PbTiO3. A sizeable splitting of the B1+E modes appears as a characteristic feature of supertetragonal phases. The peculiarity of the vanadyl V-O bond frequency in PbVO3 is also addressed.

description: Detecting communities in networks is important in various domains of applications. While a variety of methods exists to perform this task, recent efforts propose Optimal Transport (OT) principles combined with the geometric notion of Ollivier-Ricci curvature to classify nodes into groups by rigorously comparing the information encoded into nodes' neighborhoods. We present an OT-based approach that exploits recent advances in OT theory to allow tuning for traffic penalization, which enforces different transportation schemes. As a result, our model can flexibly capture different scenarios and thus increase performance accuracy in recovering communities, compared to standard OT-based formulations. We test the performance of our algorithm in both synthetic and real networks, achieving a comparable or better performance than other OT-based methods in the former case, while finding communities more aligned with node metadata in real data. This pushes further our understanding of geometric approaches in their ability to capture patterns in complex networks.

description: We construct knot invariants categorifying the quantum knot variants for all representations of quantum groups. We show that these invariants coincide with previous invariants defined by Khovanov for sl_2 and sl_3 and by Mazorchuk-Stroppel and Sussan for sl_n. Our technique is to study 2-representations of 2-quantum groups (in the sense of Rouquier and Khovanov-Lauda) categorifying tensor products of irreducible representations. These are the representation categories of certain finite dimensional algebras with an explicit diagrammatic presentation, generalizing the cyclotomic quotient of the KLR algebra. When the Lie algebra under consideration is $\mathfrak{sl}_n$, we show that these categories agree with certain subcategories of parabolic category O for gl_k. We also investigate the finer structure of these categories: they are standardly stratified and satisfy a double centralizer property with respect to their self-dual modules. The standard modules of the stratification play an important role as test objects for functors, as Vermas do in more classical representation theory. The existence of these representations has consequences for the structure of previously studied categorifications. It allows us to prove the non-degeneracy of Khovanov and Lauda's 2-category (that its Hom spaces have the expected dimension) in all symmetrizable types, and that the cyclotomic quiver Hecke algebras are symmetric Frobenius. In work of Reshetikhin and Turaev, the braiding and (co)evaluation maps between representations of quantum groups are used to define polynomial knot invariants. We show that the categorifications of tensor products are related by functors categorifying these maps, which allow the construction of bigraded knot homologies whose graded Euler characteristics are the original polynomial knot invariants.

description: Unevenly spaced samples from a periodic function are common in signal processing and can often be viewed as a perturbed equally spaced grid. In this paper, we analyze how the uneven distribution of the samples impacts the quality of interpolation and quadrature. Starting with equally spaced nodes on $[-π,π)$ with grid spacing $h$, suppose the unevenly spaced nodes are obtained by perturbing each uniform node by an arbitrary amount $\leq αh$, where $0 \leq α< 1/2$ is a fixed constant. We prove a discrete version of the Kadec-1/4 theorem, which states that the nonuniform discrete Fourier transform associated with perturbed nodes has a bounded condition number independent of $h$, for any $α< 1/4$. We go on to show that unevenly spaced quadrature rules converge for all continuous functions and interpolants converge uniformly for all differentiable functions whose derivative has bounded variation when $0 \leq α< 1/4$. Though, quadrature rules at perturbed nodes can have negative weights for any $α> 0$, we provide a bound on the absolute sum of the quadrature weights. Therefore, we show that perturbed equally spaced grids with small $α$ can be used without numerical woes. While our proof techniques work primarily when $0 \leq α< 1/4$, we show that a small amount of oversampling extends our results to the case when $1/4 \leq α< 1/2$.

description: The recent discovery of room temperature intrinsic single-photon emitters in silicon nitride (SiN) provides the unique opportunity for seamless monolithic integration of quantum light sources with the well-established SiN photonic platform. In this work, we develop a novel approach to realize planar waveguides made of low-autofluorescing SiN with intrinsic quantum emitters and demonstrate the single-photon emission coupling into the waveguide mode. The observed emission coupling from these emitters is found to be in line with numerical simulations. The coupling of the single-photon emission to a waveguide mode is confirmed by second-order autocorrelation measurements of light outcoupled off the photonic chip by grating couplers. Fitting the second-order autocorrelation histogram yields $g^{(2)}(0)=0.35\pm0.12$ without spectral filtering or background correction with an outcoupled photon rate of $10^4$ counts per second. This demonstrates the first successful coupling of photons from intrinsic single-photon emitters in SiN to monolithically integrated waveguides made of the same material. The results of our work pave the way toward the realization of scalable, technology-ready quantum photonic integrated circuitry efficiently interfaced with solid-state quantum emitters.

Evaluating a marriage enrichment programme for newly married couples in Sultanate of Oman

Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Family and household studies

description: In Oman and Arab Gulf countries, rising rates of divorce and family breakdown have increased public concern about the severity of marital and family problems. According to the ministry of justice (2002-2009), the rates of divorce increased from 1661 in 2002 to 2698 in 2009. The ministry of social development reported that the number of divorce cases provided by the Ministry according to 2003 was 7822 while in 2009 the number increased to 8199 cases, the money spent on these cases reached 4461,414 Omani Rials (Ministry of Social Development, 2003-2009). Some researchers from Gulf countries reported that the average length of some gulf countries marriage is only five to seven years (Al qashan, 2007). The main purpose of the present study was to develop, deliver and evaluate an Arabic version of the marriage enrichment programme in Omani context. In order to determine whether this programme could effectively improve the marital relationship and marital satisfaction of Omani couples. In addition, the majority of previous studies which focused on marriage enrichment, have been conducted in predominantly white, Western population (Yelsma, 1988). The current study will contribute insight into the ways couples from other cultural backgrounds interact with each other in achieving marital satisfaction, specially couples from Muslim countries. In this study, 83 newly married couples participated; 46 couples completed the six-week Marriage Enhancement Programme (MEP), completing assessments directly before, on completion and at six-months follow-up. There were 37 couples as a comparison group for measuring the impact of the programme on the experimental group. The results show that couples who completed the programme reported higher levels of satisfaction, in the form of a broad and significant improvement in their relationship on the six dimensions, than those of comparison group, all increases remained significant at six-month follow-up. These positive findings suggest the potential effectiveness of the MEP and the importance of future longitudinal outcome studies to validate its enhancement utility. It seems to warrant other culturally tailored studies to test the worth of this programme with different samples.

description: We present a method for guaranteed collision detection with toleranced motions. The basic idea is to consider the motion as a curve in the 12-dimensional space of affine displacements, endowed with an object-oriented Euclidean metric, and cover it with balls. The associated orbits of points, lines, planes and polygons have particularly simple shapes that lend themselves well to exact and fast collision queries. We present formulas for elementary collision tests with these orbit shapes and we suggest an algorithm, based on motion subdivision and computation of bounding balls, that can give a no-collision guarantee. It allows a robust and efficient implementation and parallelization. At hand of several examples we explore the asymptotic behavior of the algorithm and compare different implementation strategies.

description: Finding viable superconducting materials is of interest to the physics community as the superconductors are the playground to manifest many appealing quantum phenomena. This work exemplifies an end-to-end materials discovery towards novel MgB2-like superconductors, starting from the data-driven compound screening all the way to the experimental materialization. In addition to the known superconducting compounds, CaB2 (Tc = 9.4 ~ 28.6 K), SrGa2 (Tc = 0.1 ~ 2.4 K), BaGa2 (Tc = 0.3 ~ 3.3 K), BaAu2 (Tc = 0.0 ~ 0.5 K), and LaCu2 (Tc = 0.1 ~ 2.2 K) are newly discovered, out of ~182,000 starting structures, to be the most promising superconducting compounds that share similar atomic structures with MgB2. Moreover, BaGa2 is experimentally synthesized and measured to confirm that the compound is a BCS superconductor with Tc = 0.36 K, in good agreement with our theoretical predictions. This work provides a "once and for all" study for the MgB2-like superconductors and showcases that it is feasible to discover new materials via a data-driven approach.

description: Turbulence plays an important role in astrophysical phenomena, including core-collapse supernovae (CCSN), but current simulations must rely on subgrid models since direct numerical simulation (DNS) is too expensive. Unfortunately, existing subgrid models are not sufficiently accurate. Recently, Machine Learning (ML) has shown an impressive predictive capability for calculating turbulence closure. We have developed a physics-informed convolutional neural network (CNN) to preserve the realizability condition of Reynolds stress that is necessary for accurate turbulent pressure prediction. The applicability of the ML subgrid model is tested here for magnetohydrodynamic (MHD) turbulence in both the stationary and dynamic regimes. Our future goal is to utilize this ML methodology (available on GitHub) in the CCSN framework to investigate the effects of accurately-modeled turbulence on the explosion of these stars.

Does the use of project finance enhance shareholder value upon announcement of international joint ventures (IJVs)?
Creators: name: Acquaye, David
Publisher: name: Cardiff Metropolitan University
Year: 2022
Subjects: Financial economics

description: The empirical evidence relating to the stock market reaction to domestic joint ventures (JV) announcements suggest that the mean abnormal returns (MARs) and cumulative abnormal returns (CARs) are consistently positive, whilst those of international joint venture (IJVs) are mixed. One neglected but obvious influence of the stock market response to IJV announcements is the way they are financed. The preference for project finance over corporate finance in the financing of IJVs may have a role to play in this context. Compared with capital structure theories, this gap is seen as quantifying the role of the type of structure or debt (project or corporate finance) plays in shareholder value creation upon announcement. Using a cross-sectional study comprising of a finnal sample of 394 IJV announcements made from the years 2005 to 2010 and retrieved from the Securities Data Company (SDC) database, an event study methodology was used to derive MARs and CARs in a 2l-day window (-10,+10). The MARs and CARs are integrated into regression analyses to examine the specific role the type of finance plays in shareholder value creation upon announcement by controlling for project specific, host nation characteristics and sponsor-specific variables. The findings of the research establish that IJVs on average create value upon announcement but does not have a lasting impact on stock market valuation. As expected, the financial markets' response to IJV announcement during and after the global financial crisis (2008-2010) was not favourable. It was also found that the choice of finance matters in the market response to IJV announcements with project finance having a higher probability of eliciting a significant positive market reaction. Finally, the study revealed that whilst sector and gearing has an impact on MARs and CARs, the legal origin of the host country of the IJV did not make an impact upon announcement.

Our approach makes crucial use of analytic properties and new index theorems for the signature operator on Galois coverings with boundary. These are of independent interest and form the second main theme of the paper. The main technical novelty is the use of large scale index theory for Dirac type operators that are perturbed by lower order operators.

Through a trust-based or power-shifting philanthropic model, the Bay Ed Fund looks to empower the district stakeholders to engage in a long term, change making process over seven to ten years for the sake of student-centered, district improvements. During my time with the Bay Ed Fund, I worked on two congruent projects: first with the consulting company Estrada Darley Miller Group and next with the Bay Ed Fund itself. In partnership with South San Francisco Unified School District, both projects focused on aspects of district change. I began by examining the literature on community driven, K-12, district change efforts. I also led a project regarding the acquisition and retention of talented individuals at key district leadership positions, that can be leveraged for long-term change. My time with the Bay Ed Fund exposed me to the intricacies and challenges involved in educational philanthropic work, and I am equipped with new skills in research, literature reviews, interviewing, and systems thinking. Among the materials, you will find a visualization of the artifacts, a district profile, a literature review, the themes from the Talent Project, and a team strategy meeting agenda.

description: Combining colloidal-probe experiments and computer simulations, we analyze the solvation forces F of charged silica colloids confined in films of various thicknesses h. We show that the oscillations characterizing F(h), for sufficiently large h, are determined by the dominant wavelength of the bulk radial distribution function. As a consequence, both quantities display the same power-law density dependence. This is the first direct evidence, in a system treatable both by experiment and by simulation, that the structural wavelength in bulk and confinement coincide, in agreement with predictions from density functional theory. Moreover, theoretical and experimental data are in excellent quantitative agreement.

description: Spiral galaxies can be classified into the {\it Grand-designs} and {\it Flocculents} based on the nature of their spiral arms. The {\it Grand-designs} exhibit almost continuous and high contrast spiral arms and are believed to be driven by density waves, while the {\it Flocculents} have patchy and low-contrast spiral features and are primarily stochastic in origin. We train a convolutional neural network (CNN) model to classify spirals into {\it Grand-designs} and {\it Flocculents}, with a testing accuracy of $\mathrm{97.2\%}$. We then use the above model for classifying $\mathrm{1,354}$ new spirals from the SDSS. Out of these, $\mathrm{721}$ were identified as {\it Flocculents}, and the rest as {\it Grand-designs}. We find the median asymptotic rotational velocities of our newly classified {\it Grand-designs} and {\it Flocculents} are $218 \pm 86$ and $145 \pm 67$ respectively, indicating that the {\it Grand-designs} are mostly the high-mass and the {\it Flocculents} the intermediate-mass spirals. This is further corroborated by the observation that the median morphological indices of the {\it Grand-designs} and {\it Flocculents} are $2.6 \pm 1.8$ and $4.7 \pm 1.9$ respectively, implying that the {\it Flocculents} primarily consist of a late-type galaxy population in contrast to the {\it Grand-designs}. Finally, an almost equal fraction of of bars $\sim$ 0.3 in both the classes of spiral galaxies reveals that the presence of a bar component does not regulate the type of spiral arm hosted by a galaxy. Our results may have important implications for formation and evolution of spiral arms in galaxies.

description: We use sparse regression methods (SRM) to build accurate and explainable models that predict the stellar mass of central and satellite galaxies as a function of properties of their host dark matter halos. SRM are machine learning algorithms that provide a framework for modelling the governing equations of a system from data. In contrast with other machine learning algorithms, the solutions of SRM methods are simple and depend on a relatively small set of adjustable parameters. We collect data from 35,459 galaxies from the EAGLE simulation using 19 redshift slices between $z=0$ and $z=4$ to parameterize the mass evolution of the host halos. Using an appropriate formulation of input parameters, our methodology can model satellite and central halos using a single predictive model that achieves the same accuracy as when predicted separately. This allows us to remove the somewhat arbitrary distinction between those two galaxy types and model them based only on their halo growth history. Our models can accurately reproduce the total galaxy stellar mass function and the stellar mass-dependent galaxy correlation functions ($ξ(r)$) of EAGLE. We show that our SRM model predictions of $ξ(r)$ is competitive with those from sub-halo abundance matching and might be comparable to results from extremely randomized trees. We suggest SRM as an encouraging approach for populating the halos of dark matter only simulations with galaxies and for generating mock catalogues that can be used to explore galaxy evolution or analyse forthcoming large-scale structure surveys.

description: The moments of the single inclusive momentum distribution of hadrons in QCD jets, are studied in the next-to-modified-leading-log approximation (NMLLA) including next-to-leading-order (NLO) corrections to the alpha_s strong coupling. The evolution equations are solved using a distorted Gaussian parametrisation, which successfully reproduces the spectrum of charged hadrons of jets measured in e+e- collisions. The energy dependencies of the maximum peak, multiplicity, width, kurtosis and skewness of the jet hadron distribution are computed analytically. Comparisons of all the existing jet data measured in e+e- collisions in the range sqrt(s)~2-200 GeV to the NMLLA+NLO* predictions allow one to extract a value of the QCD parameter Lambda_QCD, and associated two-loop coupling constant at the Z resonance alpha_s(m_Z^2)= 0.1195 +/- 0.0022, in excellent numerical agreement with the current world average obtained using other methods.

description: We aim to explore spectral signatures of the predicted multi-ion UFOs in the broadband X-ray spectra of active galactic nuclei (AGNs) by exploiting an accretion disk wind model in the context of a simple magnetohydrodynamic (MHD) framework. We are focused primarily on examining the spectral dependences on a number of key properties; (1) ionizing luminosity ratio $λ_{\rm ion}$, (2) line-of-sight wind density slope $p$, (3) optical/UV-to-X-ray strength $α_{\rm OX}$, (4) inclination $θ$, (5) X-ray photon index $Γ$ and (6) wind density factor $f_D$. With an emphasis on radio-quiet Seyferts in sub-Eddington regime, multi-ion UFO spectra are systematically calculated as a function of these parameters to show that MHD-driven UFOs imprint a unique asymmetric absorption line profile with a pronounced blue tail structure on average. Such a characteristic line signature is generic to the simplified MHD disk-wind models presented in this work due to their specific kinematics and density structure. The properties of these absorption line profiles could be utilized as a diagnostics to distinguish between different wind driving mechanisms or even the specific values of a given MHD wind parameters. We also present high fidelity microcalorimeter simulations in anticipation of the upcoming {\it XRISM}/Resolve and {\it Athena}/X-IFU instruments to demonstrate that such a "tell-tale" sign may be immune to a spectral contamination by the presence of additional warm absorbers and partially covering gas.

A note on the effect of the cosmological constant on the bending of light

description: We take another look at the equations behind the description of light bending in a Universe with a cosmological constant. We show that even within the impact parameter entering into the photon's differential equation, and which is defined here with exclusive reference to the beam of light as it bends around the central mass, lies the contribution of the cosmological constant. The latter is shown to enter in a novel way into the equation. When the latter is solved our approach implies, beyond the first two orders in the mass-term and the lowest-order in the cosmological constant, a slightly different expression for the bending angle from what is previously found in the literature.

description: Dupire's functional Itô calculus provides an alternative approach to the classical Malliavin calculus for the computation of sensitivities, also called Greeks, of path-dependent derivatives prices. In this paper, we introduce a measure of path-dependence of functionals within the functional Itô calculus framework. Namely, we consider the Lie bracket of the space and time functional derivatives, which we use to classify functionals accordingly to their degree of path-dependence. We then revisit the problem of efficient numerical computation of Greeks for path-dependent derivatives using integration by parts techniques. Special attention is paid to path-dependent functionals with zero Lie bracket, called locally weakly path-dependent functionals in our classification. Hence, we derive the weighted-expectation formulas for their Greeks. In the more general case of fully path-dependent functionals, we show that, equipped with the functional Itô calculus, we are able to analyze the effect of the Lie bracket on the computation of Greeks. Moreover, we are also able to consider the more general dynamics of path-dependent volatility. These were not achieved using Malliavin calculus.

description: Skew lattices are non-commutative generalizations of lattices. The coset structure decomposition is an original approach to the study of these algebras describing the relation between its rectangular classes. In this paper we will look at the category determined by these rectangular algebras and the morphisms between them, showing that not all skew lattices can determine such a category. Furthermore, we will present a class of examples of skew lattices in rings that are not strictly categorical, and present sufficient conditions for skew lattices of matrices in rings to constitute $\wedge$-distributive skew lattices.

description: Supervised machine learning is the classification of new data based on already classified training examples. In this work, we show that the support vector machine, an optimized binary classifier, can be implemented on a quantum computer, with complexity logarithmic in the size of the vectors and the number of training examples. In cases when classical sampling algorithms require polynomial time, an exponential speed-up is obtained. At the core of this quantum big data algorithm is a non-sparse matrix exponentiation technique for efficiently performing a matrix inversion of the training data inner-product (kernel) matrix.

Demonstrate and document: The development of a best practice model for biometric access control management

Publisher: name: Cardiff Metropolitan University

Subjects: Cybersecurity and privacy not elsewhere classified

description: This thesis investigates the social, legal and ethical perceptions of participants towards the implementation of biometric access control systems within a sample of United Kingdom work-based environments. It focuses on the application of fingerprint scanning and facial recognition systems, whilst alluding to the development of more advanced (bleeding edge) technologies in the future. The conceptual framework is based on a tripartite model in which Maslow's Hierarchy of Needs is applied to the workforce whilst the principles of Utilitarianism and the Psychological Contract are applied to both management strategies and workforce perceptions. A qualitative paradigm is used in which semi-structured interviews are conducted with management and workforce participants within a sample of United Kingdom-based organisations (represented by Case Studies A-D). Discourse from these interviews are analysed, leading to the development of a series of first-cut findings for suggested "Best Practice " in the social, legal and ethical management of biometric access control systems. This process is subsequently developed with a refined sample of respondents (Case Studies A and C) culminating in the presentation of a suggested "Best Practice Model" for application to all four case studies. The model is based upon elements of a pre-determined Code of Practice (ISO/IEC 27002lnformation Technology - Security techniques - Code of Practice for Information Security Management) towards fostering acceptance of biometric technology within the workplace, in answering the question: How should organisations using biometric access control systems address social, legal and ethical concerns in the management of specific working environments in the United Kingdom?

description: We give several characterizations of stable intersections of tropical cycles and establish their fundamental properties. We prove that the stable intersection of two tropical varieties is the tropicalization of the intersection of the classical varieties after a generic rescaling. A proof of Bernstein's theorem follows from this. We prove that the tropical intersection ring of tropical cycle fans is isomorphic to McMullen's polytope algebra. It follows that every tropical cycle fan is a linear combination of pure powers of tropical hypersurfaces, which are always realizable. We prove that every stable intersection of constant coefficient tropical varieties defined by prime ideals is connected through codimension one. We also give an example of a realizable tropical variety that is connected through codimension one but whose stable intersection with a hyperplane is not.

description: Magnetoelectrics with ultra-low symmetry and spin-orbit coupling are well known to display a number of remarkable properties including nonreciprocal directional dichroism. As a polar and chiral magnet, Ni$_3$TeO$_6$ is predicted to host this effect in three fundamentally different configurations, although only two have been experimentally verified. Inspired by the opportunity to unravel the structure-property relations of such a unique light-matter interaction, we combined magneto-optical spectroscopy and first-principles calculations to reveal nonreciprocity in the toroidal geometry and compared our findings with the chiral configurations. We find that formation of Ni toroidal moments is responsible for the largest effects near 1.1 eV - a tendency that is captured by our microscopic model and computational implementation. At the same time, we demonstrate deterministic control of nonreciprocal directional dichroism in Ni$_3$TeO$_6$ across the entire telecom wavelength range. This discovery will accelerate the development of photonics applications that take advantage of unusual symmetry characteristics.

description: We investigate numerically and analytically the effects of hydrodynamics on the dynamics of topological defects in $p-$atic liquid crystals, i.e. two-dimensional liquid crystals with $p-$fold rotational symmetry. Importantly, we find that hydrodynamics fuels a generic passive self-propulsion mechanism for defects of winding number $s=(p-1)/p$ and arbitrary $p$. Strikingly, we discover that hydrodynamics always accelerates the annihilation dynamics of pairs of $\pm 1/p$ defects, and that, contrary to expectations, this effect increases with $p$. Our Letter paves the way towards understanding cell intercalation and other remodelling events in epithelial layers.
