Bell inequalities and their maximal violation
No full textBell inequalities are certain probabilistic inequalities that should hold in the context of quantum measurement under assumption of a local hidden variable model. These inequalities can be violated according to the theory of quantum mechanics and have also been violated experimentally. Bell inequalities were therefore historically used to disprove local hidden variable models as an interpretation of quantum mechanics. An interesting question is to what degree Bell inequalities can be violated according to the theory of quantum mechanics. The degree to which a particular Bell inequality can be violated is quantified by the largest violation of the Bell inequality. A central question we address in this thesis is how large the largest violation can become when considering all possible Bell inequalities. In particular the CHSH-inequality, a well-known Bell inequality, has a largest violation equal to the square root of 2 and we want to find a Bell inequality with largest violation exceeding the square root of 2. This thesis consists of two main parts. In the first part we formally define Bell inequalities and the largest violation and prove several theorems about Bell inequalities. In the second part we search for Bell inequalities with largest violation exceeding the square root of 2. We do this by first approximating the largest violation of a given Bell inequality using numerical optimization. Next, using this approximation, we use numerical optimization to maximize the largest violation. Due to run-time restrictions we were only able to consider Bell inequalities with a relatively small number of terms and were unable to find any among them with largest violation exceeding the square root of 2.Applied Mathematics | Applied Physic
Morphologic and functional correlates of synaptic pathology in the cathepsin D knockout mouse model of congenital neuronal ceroid lipofuscinosis
No full textMutations in the cathepsin D (CTSD) gene cause an aggressive neurodegenerative disease (congenital neuronal ceroid lipofuscinosis) that leads to early death. Recent evidence suggests that presynaptic abnormalities play a major role in the pathogenesis of CTSD deficiencies. To identify the early events that lead to synaptic alterations, we investigated synaptic ultrastructure and function in presymptomatic CTSD knockout (Ctsd) mice. Electron microscopy revealed that there were significantly greater numbers of readily releasable synaptic vesicles present in Ctsd mice than in wild-type control mice as early as postnatal day 16. The size of this synaptic vesicle pool continued to increase with disease progression in the hippocampus and thalamus of the Ctsd mice. Electrophysiology revealed a markedly decreased frequency of miniature excitatory postsynaptic currents (mEPSCs) with no effect on paired-pulse modulation of the evoked excitatory post synaptic potentials in the hippocampus of Ctsd mice. The reduced mEPSCs frequency was observed before the appearance of epilepsy or any morphologic sign of synaptic degeneration. Taken together, these data indicate that CTSD is required for normal synaptic function and that a failure in synaptic trafficking or recycling may bean early and important pathologic mechanism in Ctsd mice; these presynaptic abnormalities may initiate synaptic degeneration in advance of subsequent neuronal loss

The London Market Excess of Loss Spiral
No full textThis thesis explores the London Market Excess of Loss Spiral (“LMX Spiral”), a phenomenon based upon excess of loss reinsurance contracts that developed within the London reinsurance market of the 1980s. The unwinding of the LMX Spiral was a key factor in the crisis the Lloyd’s insurance market had to face in the early 1990s. However, whilst the crisis resulted in a wave of litigation in the English courts, there is no legal appraisal of the additional element of risk brought by the LMX Spiral itself. The case law instead focuses on the duties of the underwriters and various agents that fuelled its development.This situation is unsatisfactory for two reasons. Firstly, reinsurance spirals are a potential side-effect of XL reinsurance markets and therefore other spirals may develop in the future. Secondly, this thesis shows that once a reinsurance spiral reaches a certain point, it becomes unsustainable, generating instability within the relevant reinsurance market.This thesis provides a detailed legal appraisal of reinsurance spirals and a new analysis of excess of loss reinsurance contracts. The first part sets out the relevant legal principles and describes the LMX Spiral and its impact; listing, for the first time, the “Spiral Effects” identified through reports and actuarial models. The second part reviews the case law and assesses the legal nature of the excess of loss “Spiral Contracts” at the core of any reinsurance spiral, concluding that the Spiral Effects can distort the Spiral Contracts to the point where they become simple contracts of indemnity. The third part explores the nature of excess of loss reinsurance in light of the review of the Spiral Contracts, submitting that excess of loss reinsurance contracts cover both the liability of the reinsured and the relevant insured peril
'Giving honour to the Spirit' : a critical analysis and evaluation of the doctrine of pneumatological union in the Trinitarian theology of Jonathan Edwards in dialogue with Karl Barth
No full textThe extent to which the 'honour' of the Spirit influenced the theology of
Jonathan Edwards is a hitherto underdeveloped theme. Against a backdrop of
Patristic thought and in dialogue with the theology of Karl Barth, evaluation is
made of pneumatological union in Edwards' Trinitarian theology as this centres
on the nature and inter-relatedness of the 'three unions' that characterize his
theology: the union of the three Persons of the Trinity, the union of the saints
with God, and the union of the divine and human natures of Christ.
Edwards' seeks to honour the Spirit as the mutual love of the Father for the Son
within his Augustinian, Lockean model of the immanent Trinity, and as 'Person'
in the economy. The challenges of doing so within the limits of this
psychological model of the Trinity are evaluated in dialogue with the
Cappadocian Fathers and Barth.
In a manner patterned after union in the Trinity, Edwards gave prominence to the
concept of the pneumatological union of the saints with God in Christ, in
fulfilment of the self-glorifying purpose of God in creation and redemption.
Edwards' experiential theology of conversion, and his elevation of subjective
sanctification by the Spirit over objective justification in Christ, for assurance, is
contrasted with Barth's greater emphases on the Christological union of God
with humanity and objective justification in Christ. Barth's more contemplative
approach is contrasted with the overly introspective spirituality of Edwards.
Edwards' view of the role of the Spirit in the hypostatic union of God with
humanity in Christ, which is reflective of the other unions, is also evaluated in
light of Patristic, Reformed-Puritan and Barthian thought on the nature of the
humanity Christ assumed, and the doctrine of the vicarious humanity of Christ. A
more emphatic incarnational emphasis may have saved Edwards' Spirit-
honouring spirituality from an anthropocentricity which is ironical given that the
glory of God is his ontic doxological concern
What Really Sets the Upper Bound on Quantum Correlations?
No full textThe discipline of parallelization in the manifold of all possible measurement results is shown to be responsible for the existence of all quantum correlations, with the upper bound on their strength stemming from the maximum of possible torsion within all norm-composing parallelizable manifolds. A profound interplay is thus uncovered between the existence and strength of quantum correlations and the parallelizability of the spheres S^0, S^1, S^3, and S^7 necessitated by the four real division algebras. In particular, parallelization within a unit 3-sphere is shown to be responsible for the existence of EPR and Hardy type correlations, whereas that within a unit 7-sphere is shown to be responsible for the existence of all GHZ type correlations. Moreover, parallelizability in general is shown to be equivalent to the completeness criterion of EPR, in addition to necessitating the locality condition of Bell. It is therefore shown to predetermine both the local outcomes as well as the quantum correlations among the remote outcomes, dictated by the infinite factorizability of points within the spheres S^3 and S^7. The twin illusions of quantum entanglement and non-locality are thus shown to stem from the topologically incomplete accountings of the measurement results
The Einstein-Podolsky-Rosen Argument and the Bell Inequalities
No full textIn 1935 Einstein, Podolsky, and Rosen (EPR) published an important paper in which they claimed that the whole formalism of quantum mechanics together with what they called ``Reality Criterion'' imply that quantum mechanics cannot be complete. That is, there must exist some elements of reality that are not described by quantum mechanics. There must be, they concluded, a more complete description of physical reality behind quantum mechanics. There must be a state, a hidden variable, characterizing the state of affairs in the world in more details than the quantum mechanical state, something that also reflects the missing elements of reality. Under some further but quite plausible assumptions, this conclusion implies that in some spin-correlation experiments the measured quantum mechanical probabilities should satisfy particular inequalities (Bell-type inequalities). The paradox consists in the fact that quantum probabilities do not satisfy these inequalities. And this paradoxical fact has been confirmed by several laboratory experiments in the last three decades. The problem is still open and hotly debated among both physicists and philosophers. It has motivated a wide range of research from the most fundamental quantum mechanical experiments through foundations of probability theory to the theory of stochastic causality as well as the metaphysics of free will

Two-dimensional fluid model simulation of bell jar top inductively coupled plasma
No full textIn the present paper, argon (Ar) plasmas in a bell jar inductively coupled plasma (ICP) source are systematically studied over pressures from 5 to 20 mtorr and power inputs from 0.2 to 0.5 kW. In this study, both a two-dimensional (2-D) fluid model simulation and global model calculation are compared, The 2-D fluid model simulation with a self-consistent power deposition is developed to describe the Ar plasma behavior as well as predict the plasma parameter distributions, Finally, a quantitative comparison between the global model and the fluid model is made to test their validity
