description: A handful of global players dominated the telecommunications infrastructure industry in 2007. The benefits to scale were significant: substantial funding requirements were necessary to sustain continuous innovation and development of networks, products and services; key customers themselves were globalising (e.g., operators such as Telefonica and Vodafone); and low-price competition from Asia (e.g., Huawai) increased pressures towards consolidation. In 2006, French Alcatel and the US firm Lucent Technologies joined forces and in 2007 Nokia Siemens Networks (NSN) was established.

description: This is part of a case series. This case takes two perspectives on the same set of case facts about a military logistics supplier gone wrong: one from the perspective of the Department of Defense contractor ('Bill') and one from the perspective of the Kuwaiti-based supplier ('Rohit'). The case develops fictional characters to help elicit class discussion and teaching opportunities on issues of (1) how difficult it is to manage complicated ethical issues across national and cultural boundaries, and in stressful environments such as regions embroiled in military conflict, (2) how these contexts elicit in-group favouritism and out-group biases, and (3) how overcoming these limitations in global environments requires expanding one's circle of moral regard. The case involves fictional characters but the content of the case is based on publicly available information about Agility Corporation, a Kuwaiti-based supplier of food and transport for the US Department of Defense who has been indicted for fraud.

description: In 1999, Stelios Haji-Ioannou and the easyGroup management team considered whether European car rental was a business worth entering. They had an enviable track record when it came to picking market opportunities. Could this be their next success? The case describes easyCar's entry into the European car rental market and subsequent development. It is a versatile set of cases, which can be used individually, as pairs, or as a sequence of cases starting, showing the evolution of a venture from its conception to its troubles and reincarnation. It can also be taught by focusing on one or more episodes which illustrate particular aspects the instructor is interested in.This case can be used either to introduce or recap the core elements of strategy, such as market definition, industry analysis, creating new market spaces, new business model analysis, resources and capabilities. It can also help elucidate more advanced topics; i.e., show where the value lies in the value chain and how a firm should decide its positioning and link with other firms in the ecosystem; identify the challenges with planning for growth and how that links with financial strategy; and raise the upsides and downsides of s'˜Peer-to-Peers's (P2P) models, contrasted with more traditional Business-to-Consumer (B2C) models. More importantly, easyCar can be used to help students evaluate a new business model ex ante, including the role of analogies and the promises and risks of extending a firm's capabilities, and considering adaptation when things turn out worse than expected. The case offers an applied perspective on the use of analogies in strategy formation. It highlights the role of indicators of what is or isn't working in the venture, analogical reasoning and extrapolation notwithstanding.

description: This is part of a case series. The case describes the turnaround of the Belgian bank KBC under the leadership of Johan Thijs in the period 2009-2016. The case is made up of three parts - A, B and C. KBC (A) describes the situation in July 2009 when Johan This was promoted to Managing Director (MD) of the Belgian subsidiary, by far the biggest and most important unit within KBC Group. The timing is a bad one for the bank - it had just been rescued through a multibillion euro bailout by the Belgian government and the bank is on the verge of bankruptcy. Morale is at an all-time low, employees feel betrayed and are demotivated and the euro crisis is about to hit the European banking sector just when banks throughout Europe are trying to respond to the financial crisis of 2008. Johan Thijs inherits a total mess in Belgium and the case describes the facts he faces and asks the question: 'What should he do in the Belgian Unit?' At the same time to becoming MD of Belgium, he becomes member of the Group's Executive Committee (ExCo) and the case also raises the question: 'What can Thijs do as a member of the ExCo to prevent the bankruptcy of KBC Group?'

We find that the transmission of the photon can be used as a non-destructive probe for coherence of the superposition. The protocol proposed is shown to be independent of the distance between the wells in which the atoms are trapped. Furthermore, we show that by looking at the transmission in a suitable regime, a maximally entangled state can be post-selected from an unknown superposition.

Apart from buying two Barcelona apartments that got him started - thanks to his then girlfriend and now wife Lucia's good credit and a couple of hefty mortgages - and apart from maxing out a couple of credit cards in the early days and personally funding small losses in the early years, Erceg had not invested a single euro in an online travel agency business for which he had just been offered 17.3 million euros. The offer from GoTravelNow had come as a complete surprise. EnGrande, as Budgetplacess's corporate entity was called, was growing fast and was highly profitable, and Erceg wasns'st sure what to do. After weeks of negotiations, he had managed to improve the cash portion of the offer to 8.5 million euros. 'A life-changing amount of security for seven years worth of work,' he thought. Should he take the offer that was on the table? It was time to decide.

description: Single-field inflation, arguably the simplest and most compelling paradigm for the origin of our Universe, is strongly supported by the recent results of the Planck satellite and the BICEP2 experiment. The results from Planck, however, also confirm the presence of a number of anomalies in the Cosmic Microwave Background (CMB), whose origin becomes problematic in single-field inflation. Among the most prominent and well-tested of these anomalies is the Cold Spot, which constitutes the only significant deviation from gaussianity in the CMB. Planck's non-detection of primordial non-gaussianity on smaller scales thus suggests the existence of a physical mechanism whereby significant non-gaussianity is generated on large angular scales only. In this letter, we address this question by developing a localized version of the inhomogeneous reheating scenario, which postulates the existence of a scalar field able to modify the decay of the inflaton on localized spatial regions only. We demonstrate that if the Cold Spot is due to an overdensity in the last scattering surface, the localization mechanism offers a feasible explanation for it, thus providing a physical mechanism for the generation of localized non-gaussianity in the CMB. If, on the contrary, the Cold Spot is caused by a newly discovered supervoid (as recently claimed), we argue that the localization mechanism, while managing to enhance underdensities, may well shed light on the rarity of the discovered supervoid.

description: The application of modern machine learning to retinal image analyses offers valuable insights into a broad range of human health conditions beyond ophthalmic diseases. Additionally, data sharing is key to fully realizing the potential of machine learning models by providing a rich and diverse collection of training data. However, the personally-identifying nature of retinal images, encompassing the unique vascular structure of each individual, often prevents this data from being shared openly. While prior works have explored image de-identification strategies based on synthetic averaging of images in other domains (e.g. facial images), existing techniques face difficulty in preserving both privacy and clinical utility in retinal images, as we demonstrate in our work. We therefore introduce k-SALSA, a generative adversarial network (GAN)-based framework for synthesizing retinal fundus images that summarize a given private dataset while satisfying the privacy notion of k-anonymity. k-SALSA brings together state-of-the-art techniques for training and inverting GANs to achieve practical performance on retinal images. Furthermore, k-SALSA leverages a new technique, called local style alignment, to generate a synthetic average that maximizes the retention of fine-grain visual patterns in the source images, thus improving the clinical utility of the generated images. On two benchmark datasets of diabetic retinopathy (EyePACS and APTOS), we demonstrate our improvement upon existing methods with respect to image fidelity, classification performance, and mitigation of membership inference attacks. Our work represents a step toward broader sharing of retinal images for scientific collaboration. Code is available at https://github.com/hcholab/k-salsa.

description: The case describes how Mike Bracken, the newly appointed head of the UK Government Digital Service (GDS), took on the massive challenge of setting up, from scratch, a centralised team to deliver online public services efficiently online across all of the government's digital channels. This involved not merely overcoming great operational and technical challenges - legacy IT systems, lack of recognition and reward for specialist skills - but instigating deep cultural change and securing senior-level buy-in to make the necessary changes happen. The case illustrates how to approach implementing large-scale change across a highly bureaucratic organisation; in this case, the UK government. As such, it is a beautiful illustration of where agile works well. One key point to note is that, rather than focusing on the specifics of agile working, it demonstrates when agile methods can be a very powerful tool for enabling change. It also illustrates the importance of a decisive leader in getting an agile way of working implemented (and to some extent, risk-taking on the part of Mike Bracken and his sponsor in government). We will discuss the pros and cons of this approach.

description: The case is intended as a vehicle for analysis of the challenges involved in launching an innovative product. It is set against the background of the wave of innovation in the vehicle market, as manufacturers race to replace internal combustion engines (ICEs) with electric power. Protean Electric, a company of British origin but now Chinese-owned, aims to introduce another level of innovation by introducing its in-wheel motor (IWM) technology to electric vehicles (EVs). Instead of simply replacing an internal combustion engine with an electric battery unit, Protean technology dispenses with the central powertrain and mounts electric power units in some or all of the wheels of the vehicle. The company is committed to being part of the entry into the mainstream passenger EV market of Evergrande, its Chinese owners, but has historically also looked at other sectors such as urban shuttles and delivery fleets, and has retained the ability to continue to develop products for those sectors. It also has to consider the emerging consensus that the transport market of the future will shift away from individual ownership towards a model known as CASE (connected, autonomous, shared, electrified). The contrast between the 'niche' IWM innovation and the market-wide electric revolution highlights the key concepts in new-product market analysis.

description: We match data on performance in a multiple-choice examination with data on risk preferences from a classroom experiment. Students who are more loss averse leave more questions unanswered and perform worse in the exam when an incorrect answer is penalized compared with no answer. Thus, loss aversion parameters extracted from lottery choices in a controlled experiment have predictive power in a field environment of decision-making under uncertainty. Furthermore, the degree of loss aversion appears to be persistent over time, as the experiment was conducted three months prior to the exam. Important differences across genders are partly explained by differences in loss aversion.

These measures were initially formulated either for photonic systems or spin ensembles. Here, we compare them through a simple model which maps photonic states to spin ensembles. On the one hand, we reveal problems for some spin measures to handle correctly photonic states that typically are considered to be macroscopically quantum. On the other hand, we find significant similarities between other measures even though they were differently motivated.

description: It is well-known that entanglement of formation (EOF) and relative entropy of entanglement (REE) are exactly identical for all two-qubit pure states even though their definitions are completely different. We think this fact implies that there is a veiled connection between EOF and REE. In this context, we suggest a procedure, which enables us to compute REE from EOF without relying on the converse procedure. It is shown that the procedure yields correct REE for many symmetric mixed states such as Bell-diagonal, generalized Vedral-Plenino, and generalized Horodecki states. It also gives a correct REE for less symmetric Vedral-Plenio-type state. However, it is shown that the procedure does not provide correct REE for arbitrary mixed states.

Manfred and Thomas ran their own separate, and longer-established branch in Mexico City. Simon had won some large, multinational customers, and had benefited from the increase in imports from China. By focusing on customer service, and by building up a hard-working team, he had grown bigger than the original Mexico City operation.

Should it be launched under the Nespresso or Nescafe brand name (or neither)? and how could Nestle avoid potential cannibalisation of its Nespresso and / or Nescafe sales?

description: Using the density-matrix renormalization-group algorithm (DMRG) and a finite-size scaling analysis, we study the properties of the one-dimensional completely-anisotropic spin-1/2 XYZ model with Dzyaloshinsky-Moriya (DM) interactions. The model shows a rich phase diagram: depending on the value of the coupling constants, the system can display different kinds of ferromagnetic order and Luttinger-liquid behavior. Transitions from ferromagnetic to Luttinger-liquid phases are first order. We thoroughly discuss the transition between different ferromagnetic phases, which, in the absence of DM interactions, belongs to the XX universality class. We provide evidence that the DM exchange term turns out to split this critical line into two separated Ising-like transitions and that in between a disordered phase may appear. Our study sheds light on the general problem of strongly-interacting spin-orbit-coupled bosonic gases trapped in an optical lattice and can be used to characterize the topological properties of superconducting nanowires in the presence of an imposed supercurrent and of interactions.

description: For most quantum mechanical systems of physical interest, central properties like the energy spectrum are not exactly accessable by analytical methods. In single-particle systems, however, many of the quantum features can be analytically adressed in semiclassical approximations that have been developed over the last decades and are now well established and sophisticated. This work presents the transfer of semiclassical methods to systems of many identical and indistinguishable particles, showing the conceptual differences to single-particle systems. The concepts of the counterpart of periodic orbit theory are adressed and a classical sum rule is developed as a many-body-extension of a similar sum rule for single-particle systems, which is an useful tool for estimating statistical properties of many-body energy spectra. The central result is a novel analytical approach to the calculation of the mean density of states in many-body billiard systems. The presented method makes explicit the intrinsic geometry inherent in the symmetrization postulate and, in the spirit of the usual Weyl expansion for the smooth part of the density of states in single-particle confined systems, the result takes the form of a sum over clusters of particles moving freely around manifolds in configuration space invariant under elements of the group of permutations. Being asymptotic, the approximation gives increasingly better results for large excitation energies and comparison shows that it coincides with the celebrated Bethe estimate in the appropriate region. Moreover, the construction gives the correct high energy asymptotics expected from general considerations, and shows that the emergence of the fermionic ground state is actually a consequence of an extremely delicate large cancellation effect. Remarkably, the expansion in cluster zones is naturally incorporated for systems of interacting particles, opening the road to address the fundamental problem about the interplay between exchange symmetry and interactions in many-body systems of identical particles.

Jim Slater, Managing Director of Costa Enterprises, is thinking about a management consultant's offer to build the next generation coffee machine for his division. The company's business model has historically been built on incremental improvements, but this proposal would involve a 'step change' in how new products are developed. Costa Enterprises rolls out self-service vending machines ('concessions') that deliver quality coffee to customers in areas not served by premium high street cafes. The proposal Slater is considering is to build the next generation concession. However, handing over control of such an important, venture to an outsider seems like a significant risk for Slater to take.

description: The vacuum is the lowest energy state of a field in a certain region of space. This definition implies that no particles can be present in the vacuum state. In classical physics, the only features of vacuum are those of its geometry. For example, in the general theory of relativity the geometry is a dynamical structure that guides the motion of matter, and, in turn, it is bent and curved by the presence of matter. Other than this, the classical vacuum is a structure void of any physical properties, since classically properties are strictly associated with physical objects such as particles and finite-amplitude fields. The situation is very different in quantum physics. As I will show in this paper, the difference stems from the fact that in quantum physics the properties are not strictly tied to objects. We know for example that physical properties come into existence - as values of observables - only when the object is measured. Thus, quantum physics allows us to detach properties from objects. This has consequences: one does not need pre-existing real objects to create actual properties, and indeed under certain perturbations the quantum vacuum produces observable effects such as energy shifts and creation of particles. An open question is if by necessity the vacuum comes with an embedded geometry, and if it is possible to construct viable physical theories in which geometry is detached from the vacuum.

This had bothered him for years, but his positive intentions never seemed to translate into real changes toward equalising the representation of women and men on air. A car drive where Atkins spent an hour listening to a radio show with no female guests, paired with a leadership development trip to Silicon Valley, pushed him from intention into action and he decided to find a way to use data to drive change. This case study describes the idea that Atkins had, how he tested it on his own show and how he - after a few months of success - expanded it first throughout the BBC to over 500 content teams globally and then to more than 25 external partner organisations (and counting). The case offers an example of how transformative organisational change promoting gender diversity can come from an unexpected source and explores the personal, leadership and organisational challenges that emerge along the way.

description: Social reinforcement and modular structure are two salient features observed in the spreading of behavior through social contacts. In order to investigate the interplay between these two features, we study the generalized epidemic process on modular networks with equal-sized finite communities and adjustable modularity. Using the analytical approach originally applied to clique-based random networks, we show that the system exhibits a bond-percolation type continuous phase transition for weak social reinforcement, whereas a discontinuous phase transition occurs for sufficiently strong social reinforcement. Our findings are numerically verified using the finite-size scaling analysis and the crossings of the bimodality coefficient.

description: Astrophysical charge-free black holes are known to satisfy no-hair relations through which all multipole moments can be specified in terms of just their mass and spin angular momentum. We here investigate the possible existence of no-hair-like relations among multipole moments for neutron stars and quark stars that are independent of their equation of state. We calculate the multipole moments of these stars up to hexadecapole order by constructing uniformly-rotating and unmagnetized stellar solutions to the Einstein equations. For slowly-rotating stars, we construct stellar solutions to quartic order in spin in a slow-rotation expansion, while for rapidly-rotating stars, we solve the Einstein equations numerically with the LORENE and RNS codes. We find that the multipole moments extracted from these numerical solutions are consistent with each other. We confirm that the current-dipole is related to the mass-quadrupole in an approximately equation of state independent fashion, which does not break for rapidly rotating neutron stars or quark stars. We further find that the current-octupole and the mass-hexadecapole moments are related to the mass-quadrupole in an approximately equation of state independent way to $\sim 10%$, worsening in the hexadecapole case. All of our findings are in good agreement with previous work that considered stellar solutions to leading-order in a weak-field expansion. The quartic in spin, slowly-rotating solutions found here allow us to estimate the systematic errors in the measurement of the neutron star's mass and radius with future X-ray observations, such as NICER and LOFT. We find that the effect of these quartic-in-spin terms on the quadrupole and hexadecapole moments and stellar eccentricity may dominate the error budget for very rapidly-rotating neutron stars. The new universal relations found here should help to reduce such systematic errors.

description: In August 2019 CEO David Craig was considering the likely benefits and challenges of merging his company, financial-markets data and infrastructure provider Refinitiv, with the London Stock Exchange Group. Craig had led a turnaround of Thomson Reuters’ Financial & Risk division (F&R), then used investment from a private equity consortium led by Blackstone to carve out F&R from Thomson Reuters and create Refinitiv as an independent company. The carve-out had been successful, but global financial markets were evolving fast. Initial industry reaction to the proposed deal was positive; however some analysts questioned whether it would be approved by regulators and expressed concern over the complexity of integrating the two companies. With the industry changing so quickly, could the momentum created in Refinitiv be maintained in the new combined entity?

description: Binary stars have long been known to show mutual and precisely periodic eclipses, if their orbit is favourably inclined to our line of sight. However, more recently space telescope missions such as Kepler have provided long-term precision light-curves for thousands of stars, enabling analyses of binary star eclipse timing variations to search for perturbing low-mass sub-stellar companions, namely brown dwarfs and planets. This thesis thus comprises three interrelated studies, as follows. (1) The extent to which eclipse time variations can detect binary star low-mass bodies is simulated for Kepler Eclipsing Binary Star Catalog stars using empirical data from the catalog as a starting point. The analysis finds that even planetary mass companions are readily detectable with eclipse time variations, although successful detection is strongly dependent on the orbital period of the host eclipsing binary star, and the orbital period and eccentricity of the third body. The detectable range of companion body masses and orbital periods also can be reliably estimated simply, using just two equations. (2) In a study of orbital dynamics, for those binary stars found to produce complex eclipse timing variations, their evolving system orbital configuration is inferred, and their long-term dynamical stability is simulated. The analysis finds that even complex eclipse time variations are explainable by low-mass, even planetary, companions in stable orbits, and where highly eccentric third bodies around eccentric binary stars can explain a complex 'flip-flop' feature seen in some observed-calculated diagrams. For some proposed new low-mass companions, the simulated orbits are expected to be stable over long dynamical timescales, with the companions remaining detectable. (3) In terms of new planetary detections, in a study of KIC 5095269, a planietary mass companion has been found in a highly inclined orbit relative to the orbit of the host stars. The eclipse time variation analysis for this system indicates a 7.70 Jupiter mass planet in a 237.7 day orbit, stable for at least ten million years. In conclusion, this thesis has established the feasibility of eclipsing timing variations as a way to survey binary stars for brown dwarf and planetary companions. In the future, space telescope surveys such as those being done by the Transiting Exoplanet Survey Satellite (TESS) will accrue additional useful eclipsing binary star light curves, and enable more extensive searches for binary star low-mass companions.
Magnetic field modulated Kondo effect in a single-magnetic-ion molecule

description: We study numerically the low-temperature electronic transport properties of a single-ion magnet with uniaxial and transverse spin anisotropies. We find clear signatures of a Kondo effect caused by the presence of a transverse (zero-field) anisotropy in the molecule. Upon applying a transverse magnetic field to the single-ion magnet, we observe oscillations of the Kondo effect due to the presence of diabolical (degeneracy) points of the energy spectrum of the molecule caused by a geometrical phase interference effects similar to those observed in the quantum tunneling of multi-ion molecular nanomagnets. The field-induced lifting of the ground state degeneracy competes with the interference modulation, resulting in some cases in a suppression of the Kondo peak.

description: In March 2021, Greensill Capital, the UK-based leading supply chain financing provider, with 16 offices across the world, filed for insolvency; its Germany-based bank closed by regulators. Less than two years earlier, Greensill had received a $1.5 billion investment from SoftBank's Vision Fund, valuing the company at $3.5 billion. By 2020, the company was targeting a $7 billion valuation with a potential IPO. Supply chain finance was a centuries-old method that enabled companies to better manage their working capital. Greensill had ridden the wave of technological advances to bring supply chain finance into the 21st century, but it had spectacularly failed. The repercussions of this failure touched SoftBank, Credit Suisse and the steel empire of Sanjeev Gupta, and stretched across the globe, potentially putting tens of thousands of jobs at risk. The failure also revealed one of the biggest lobbying scandals to hit the UK Government. What caused the epic fall of Greensill? And how would it affect the future of supply chain finance?

description: Eden McCallum is a Management Consulting firm founded by two ex-McKinsey partners. It has offices in London, Amsterdam and Zurich, and is planning further expansion. The company is founded using a distinctive new business model, based on operating a pool of experienced, freelance consultants. Hence, it operates as a double-sided market. Eden McCallum's 15 partners secure client projects and then assemble teams of consultants to work on these projects. They screen consultants extensively before admitting them into their pool. Furthermore, the company provides office space, a team of analysts, and operational assistance (in terms of IT, legal, billing, etcetera). The case stimulates discussion in terms of how the company might grow, whether its value proposition can remain distinctive as it expands, and how it can attract and retain the people in the various markets - independent consultants, partners and staff - needed to make further growth a success. In particular, the case explores business model innovation by creating a novel value proposition for employees, i.e., by giving management consultants more control over their time and lives.
