Securing DICOM images through automatic selective encryption
Creators: name: Natsheh, Amar
Publisher: name: Loughborough University
Year: 2019
Subjects: Other information and computing sciences not elsewhere classified

description: Securing Digital Imaging and Communications in Medicine (DICOM) images are essential to protect the privacy of patients, especially in the era of communications, telemedicine and eHealth/mHealth. This increases the demand for rapid security. Nevertheless, a limited number of research work has been conducted to ensure the security of DICOM images while minimising the processing time. Hence, this thesis introduces a novel selective encryption approach to reduce the processing time and sustain robustness of security. The proposed approach selects regions within medical images automatically in the spatial domain using pixel thresholding segmentation technique, then compresses and encrypts them using different encryption algorithms based on their importance. The presented approaches in this thesis are developed for multi-frame and single-frame DICOM images. As the medical images of the same modality and the same body part for different patients have the same statistical distribution, it is possible to segment images from the same modality and same body part into Region of Interest (ROI) and Region of Background (ROB) using a pre-defined threshold. In the case of small ROI, an adaptive two-region encryption approach is applied to single and multi-frame DICOM image. In which, the ROB is encrypted using a light encryption algorithm, while the ROI is encrypted using a sophisticated encryption algorithm. For multi-frame DICOM images, additional time saving has been achieved using one segmentation map based on a pre-defined reference frame for all the DIOCM frames. On the other hand, if ROI is very large, i.e. Mammography DICOM images, the ROI is further split into three regions (multi-region) based on potential security threats, using a novel mathematical model that guarantees shorter encryption time in comparison with the Naive encryption approach. After that, each region is compressed using lossless compression approach, and then encrypted using a different encryption algorithm with different key lengths based on its pixels' intensity. Results from the presented approaches show that processing time is reduced by an average of 54% in comparison with the Naïve encryption approach while maintaining the security of the DICOM images. Further, cryptanalysis metrics are utilised to evaluate the proposed approaches, which indicate good robustness against wide varieties of attacks.

In recent years beta-amino acids have gained considerable attention due to their applications in medicinal chemistry, particularly in peptidomimetics. As a result, a plethora of synthetic methods for accessing beta-amino acids have been developed. However, a majority of these methods have shortcomings. As a result there is an ongoing requirement to develop new methodologies to produce beta-amino acids that possess multifunctional substitution. Herein presented are novel strategies to produce known and novel beta-amino acid derivatives. A novel multi step pathway was developed to access beta 3 -amino acids. In this approach, a set of N-protected alpha-amino acids were converted to N-protected amino nitroalkanes. The nitroalkanes were then subjected to the Nef reaction to afford a variety of enantiomerically pure N-protected beta3 -amino acids. The beta 3 -amino acids were then used to produce the 1,3-oxazinan-6-one scaffold, which was used as a synthon to access a variety of functionally substituted beta 2,2,3 -amino acids, cyclic beta 2,3 -amino acids and beta-amino ketones. Firstly, 1,3-oxazinan-6-ones were enolised and trans-selectively intercepted with various electrophiles. The resulting 5-substituted adducts were enolised again, and then intercepted with different electrophiles to form differentially 5,5-disubstituted products with high diastereoselectivity. The 5,5-dialkylated 1,3-oxazinan-6-ones were then transformed into a variety of beta2,2,3 -substituted amino acids. In addition, the enolates of the 4-vinyl, 4-allyl and 4-butenyl-1,3-oxazinan-6-ones were allylated with various alkenyl electrophiles diastereoselectively. The resulting 4,5-bisalkene adducts were subjected to ring closing metathesis to provide the 4,5-cyclic-1,3- oxazinan-6-ones. The metathesis products were subsequently converted into a variety of 5-, 6- and 7-membered cyclic beta2,3 -amino acids. And lastly, the 4-substituted 1,3-oxazinan-6-one was enolised and then intercepted with various acyl halides. The acylated products were subjected to acidic conditions to give enantiomerically pure N-protected beta-amino ketones. The methodology described has provided novel avenues to a variety of functionalised beta-amino acids and beta-amino ketones that have important applications in the design of medicinal therapeutics.
Magnetic properties of bilayer Sr$_3$Ir$_2$O$_7$: role of epitaxial strain and oxygen vacancies

description: Using {\it ab initio} methods, we investigate the modification of the magnetic properties of the $m=2$ member of the strontium iridates Ruddlesden-Popper series Sr$_{m+1}$Ir$_{m}$O$_{3m+1}$, bilayer Sr$_3$Ir$_2$O$_7$, induced by epitaxial strain and oxygen vacancies. Unlike the single layer compound Sr$_2$IrO$_4$, which exhibits a robust in-plane magnetic order, the energy difference between in-plane and out-of-plane magnetic orderings in Sr$_3$Ir$_2$O$_7$ is much smaller and it is expected that small external perturbations could induce magnetic transitions. Our results indicate that epitaxial strain yields a spin-flop transition, that is driven by the crossover between the intralayer $J_1$ and interlayer $J_2$ magnetic exchange interactions upon compressive strain. While $J_1$ is essentially insensitive to strain effects, the strength of $J_2$ changes by one order of magnitude for tensile strains $\geq$ 3~\%. In addition, our study clarifies that the unusual in-plane magnetic response observed in Sr$_3$Ir$_2$O$_7$ upon the application of an external magnetic field originates from the canting of the local magnetic moments due to oxygen vacancies, which tilt the octahedral networks - thereby allowing for noncollinear spin configurations.

description: At low temperatures bosons typically condense to minimize their single-particle kinetic energy while interactions stabilize superfluidity. Optical lattices with artificial spin-orbit coupling challenge this paradigm because here kinetic energy can be quenched in an extreme regime where the single-particle band flattens. To probe the fate of superfluidity in the absence of kinetics we construct and numerically solve interaction-only tight-binding models in flat bands. We find that novel superfluid states arise entirely from interactions operating in quenched kinetic energy bands, thus revealing a distinct and unexpected condensation mechanism. Our results have important implications for the identification of quantum condensed phases of ultracold bosons beyond conventional paradigms.

Cartan subalgebras of tensor products of free quantum group factors with arbitrary factors

description: Let $\mathbb{G}$ be a free (unitary or orthogonal) quantum group. We prove that for any non-amenable subfactor $N\subset L^\infty(\mathbb{G})$, which is an image of a faithful normal conditional expectation, and for any $σ$-finite factor $B$, the tensor product $N \otimes B$ has no Cartan subalgebras. This generalizes our previous work that provides the same result when $B$ is finite. In the proof, we establish Ozawa--Popa and Popa--Vaes's weakly compact action on the continuous core of $N \otimes B$ as the one relative to B, by using an operator valued weight to B and the central weak amenability of $\mathbb{G}$.

Signatures of Earth-scattering in the direct detection of Dark Matter

description: Direct detection experiments search for the interactions of Dark Matter (DM) particles with nuclei in terrestrial detectors. But if these interactions are sufficiently strong, DM particles may scatter in the Earth, affecting their distribution in the lab. We present a new analytic calculation of this `Earth-scattering' effect in the regime where DM particles scatter at most once before reaching the detector. We perform the calculation self-consistently, taking into account not only those particles which are scattered away from the detector, but also those particles which are deflected towards the detector. Taking into account a realistic model of the Earth and allowing for a range of DM-nucleon interactions, we present the EarthShadow code, which we make publicly available, for calculating the DM velocity distribution after Earth-scattering. Focusing on low-mass DM, we find that Earth-scattering reduces the direct detection rate at certain detector locations while increasing the rate in others. The Earth's rotation induces a daily modulation in the rate, which we find to be highly sensitive to the detector latitude and to the form of the DM-nucleon interaction. These distinctive signatures would allow us to unambiguously detect DM and perhaps even identify its interactions in regions of the parameter space within the reach of current and future experiments.

Although, the financing gap for SMEs is more pervasive in developing economies, there is a vacuity of research that examines the situation in these countries. Hence, the purpose of this study is to investigate the access to bank finance and related issues in the SME sector of Sri Lanka. The empirical evidence for this study is drawn from the Sri Lanka enterprise survey data set obtained from the World Bank. The logistic regression model was used to empirically test the literature-driven hypotheses. However, before proceeding to the logistic regression results, preliminary chi-square results are presented in order to obtain a better understanding of univariate differences and associations in the data. This study finds that access to bank finance is largely determined by ownership type of the firm, industry sector, location of the firm, availability of audited financial statements and the perception of the owner-manager on access to finance. This study also reviews several capital structure theories and human capital theories and finds that these theories provide little support in understanding the financial behaviour of SMEs in Sri Lanka. This dissertation contributes to the understanding of the access to finance in the SME sector in three aspects. First, to the knowledge of the researcher, this study is the first examination of the access to finance by SMEs in Sri Lanka. Second, this study brings together research from several disciplines to develop a conceptual framework for understanding the SME financing situation. Third, the study increases knowledge of the perceptions of SME owner-managers regarding their access to finance. In terms of policy, the findings of this dissertation provide policy makers with new insights on how to tailor macroeconomic policy and regulations to help overcome the finance gap in this important sector of the economy. In particular, policy makers can make informed decisions that are based on this research to articulate policies, to develop training programmes, and to design support systems that can positively address the factors affecting access to credit to SMEs in Sri Lanka. The findings of this study can be replicated in other developing countries as well.

We show that this object allows to calculate the conditional expectation of the squared eigenvalue condition number. We give examples and we provide cross-check of the analytic prediction by the large scale numerics.

EVALUATION OF ANIMAL AND PLANT BY-PRODUCTS AS CONSTITUENTS IN DIETS FOR SEABREAM SPARUS AURATA L.
Creators: name: NENGAS, IOANNIS
Publisher: name: University of Plymouth
Year: 1991

description: The principle aim of the study was to evaluate the nutritional value of animal and plant by-products, with the objective of improving the cost effectiveness of diets for culturing seabream (Sparus aurata). The programme of work was initially directed towards applying the current methodology used in fish nutrition research to establish reliable digestibility coefficients for various feed ingredients. A selection of animal and plant materials were tested for digestibility within a reference basal diet designed for seabream. Ingredients for special consideration included poultry by-product meal, feather meal, meat and bone meal, solvent extracted and full fat soyabean meal as well as various other plant derived mater1als. Comparative values for protein, energy and lipid digestibility coefficients were assessed. On the basis of these measurements, experiments were undertaken to evaluate the optimum inclusion levels of promising protein and energy sources as a replacement for the fishmeal component in diets for seabream. Emphasis was made on recent advances in feed processing technology. Raw materials were evaluated in terms of proximate analysis, amino acid profiles and the degree of heat treatment effects on protein quality and availability. Several indices relating to these included lysine availabil1ty, cresol red values and trypsin inhibitor levels for soya products. Growth performance and feed utilization trials were conducted mainly on juvenile fish in recirculation systems under controlled conditions of temperature and salinity. Nutritional parameters such as specific growth rate (SGR), feed efficiency ~FE) and protein utilization parameters were determined 1n each successive trial. The results were favourable with respect to the partial inclusion of animal products in seabream diets. Poultry byproduct meals proved encouraging even at high inclusion levels. The growth performance of fish fed soyabean meal and full fat soya were initially favourable and merited further consideration. These preliminary trials led to a series of practical diet formulations to contain multi-in9redient components, which confirmed previous findings. Var1able results, however, were reported for full fat soyabean meal in this experiment. Finally, the programme of research was presented in the context of the rapidly expanding mariculture industries of southern Europe w1th a particular relevance to Greece.

It then follows that each saturated fusion system over a $2$-group of order at most $2^9$ is realizable. What is most interesting about this result is the method of proof: we show that among $2$-groups with order in this range, the ones which can be Sylow $2$-subgroups of finite simple groups are almost completely determined by criteria based on Bender's classification of groups with strongly $2$-embedded subgroups.
Intertwining Operator in Thermal CFT$_{d}$
Creators: name: Ohya, Satoshi
Publisher: name: arXiv
Year: 2016
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: It has long been known that two-point functions of conformal field theory (CFT) are nothing but the integral kernels of intertwining operators for two equivalent representations of conformal algebra. Such intertwining operators are known to fulfill some operator identities---the intertwining relations---in the representation space of conformal algebra. Meanwhile, it has been known that the S-matrix operator in scattering theory is nothing but the intertwining operator between the Hilbert spaces of in- and out-particles. Inspired by this algebraic resemblance, in this paper we develop a simple Lie-algebraic approach to momentum-space two-point functions of thermal CFT living on the hyperbolic spacetime $\mathbb{H}^{1}\times\mathbb{H}^{d-1}$ by exploiting the idea of Kerimov's intertwining operator approach to exact S-matrix. We show that in thermal CFT on $\mathbb{H}^{1}\times\mathbb{H}^{d-1}$ the intertwining relations reduce to certain linear recurrence relations for two-point functions in the complex momentum space. By solving these recurrence relations, we obtain the momentum-space representations of advanced and retarded two-point functions as well as positive- and negative-frequency two-point Wightman functions for a scalar primary operator in arbitrary spacetime dimension $d\geq3$.

description: We apply the machinery of relative tensor triangular Chow groups to the action of the derived category of quasi-coherent sheaves on a noetherian scheme $X$ on the derived category of quasi-coherent $\mathcal{A}$-modules, where $\mathcal{A}$ is a (not necessarily commutative) quasi-coherent $\mathcal{O}_X$-algebra. When $\mathcal{A}$ is commutative and coherent, we recover the tensor triangular Chow groups of the relative Spec of $\mathcal{A}$. We also obtain concrete descriptions for integral group algebras and hereditary orders over curves, and we investigate the relation of these invariants to the classical ideal class group of an order. An important tool for these computations is a new description of relative tensor triangular Chow groups as the image of a map in the K-theoretic localization sequence associated to a certain Verdier localization.

Electronic properties of surface conducting hydrogen-terminated diamond

Year: 2023

description: Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the Department of Physics, School of Engineering and Mathematical Sciences, Faculty of Science, Technology and Engineering, La Trobe University, Bundoora.

The present work details a series of investigations primarily focused on the surface conductivity that arises at the hydrogen-terminated diamond surface. The goal is to understand the surface transfer doping process between the diamond and acceptor overlayer, and also the electronic behaviour of the accumulation layer that forms below the diamond surface. The significant research milestones presented are: An angle-resolved photoemission study of hydrogen-terminated [100] diamond to determine the bulk valence band dispersion of diamond and subsequently determine a one-band carrier effective mass. In-situ simultaneous photoemission, Kelvin probe and electrical measurements to study the response of surface conducting diamond to doping with C60F48. This determines a ‘universal’ curve to describe band bending as a function of accumulated holes, and the formation of an interface dipole that is directly dependent on the amount of transferred charge. High-resolution surface sensitive photoemission spectroscopy reveals C60F48 molecules on the hydrogen-terminated diamond surface have two distinct charge states. These charge states correspond to molecules that participate in charge transfer and those that do not. Quantitative analysis of the ratio of these charge states has led to the development of a model that explains the charge transfer process in diamond. This model has been applied to angle-resolved photoemission data of epitaxial graphene grown on Silicon Carbide doped with C60F48 to successfully the explain the observed behaviour. Finally, we report on the observation of weak localization and weak anti-localization effects in surface conducting diamond at low temperature. This not only conclusively proves the two-dimensional nature of the hole gas in surface conducting diamond, but also reveals the presence of strong spin-orbit interaction at the surface of hydrogen-terminated diamond that could lead to new devices incorporating spin manipulation. The results chapters in this thesis are comprised of a collection of published journal articles.

description: Die durch den sogenannten Portevin-Le Châtelier (PLC)-Effekt hervorgerufene, inhomogene und instabile plastische Verformung von metallischen Werkstoffen verursacht eine erhöhte Oberflächenrauheit und kann die Duktilität und Umformbarkeit beeinträchtigen. Dadurch ist der Einsatz dieser Werkstoffe in solchen Bereichen nur eingeschränkt möglich, in denen es auf eine gute Oberflächenqualität ankommt (z.B. Bleche der PKW-Außenhaut). Das Ziel dieser Forschungsarbeit ist es, durch die experimentelle Untersuchung des Mechanismus der Bandbildung und -ausbreitung und deren Simulation einen Beitrag zu einem verbesserten Verständnis dieser Prozesse zu leisten. Dazu werden in dieser Arbeit zunächst verschiedene experimentelle Methoden entwickelt. Dazu gehören die Aufnahme und Auswertung von Thermokamerabildserien, eine Bildkorrelationsmethode zur Bestimmung von Dehnungsfeldern auf Basis von Infrarot- und CCDKamerabildern und der Aufbau eines Versuchstands zur Analyse des PLC-Verhaltens bei lokaler Lasererwärmung. Auf Basis dieser Methoden werden dann die Entstehung und Ausbreitung von PLC- und Lüdersbändern sowie der Wechselwirkung zwischen PLC- und Scherbändern im Probensteg und im Übergangbereich zwischen Steg und Kopf der Zugproben experimentell untersucht. In diesem Zusammenhang wird auch der Einfluss von Temperaturgradienten auf das Ausbreitungsverhalten der PLC-Bänder betrachtet. Parallel zu den Experimenten wird das Verhalten der PLC-Bänder auf Basis der Modelle von Estrin/McCormick und Hähner simuliert. Dabei wird erstmalig die thermomechanischen Kopplung in das Modell eingeführt, um die Rückwirkung der durch die plastische Verformung freigesetzten Wärme bzw. Temperaturerhöhung auf das Bandverhalten zu berücksichtigen. Der Vergleich von Experiment und Simulation zeigt eine qualitativ gute Übereinstimmung bei der Morphologie und Kinematik der PLC-Bänder sowie bei der Scherband-PLC-Band-Wechselwirkung. Durch Berücksichtigung der Temperaturkopplung werden der Ort der Bandbildung und die Spannungs-Dehnungs-Kurve besser vorhergesagt. Der quantitative Vergleich offenbart aber auch Diskrepanzen zwischen dem experimentell beobachteten und dem simulierten Bandverhalten. Sowohl unzutreffend gewählte Werte für die Modellparameter bei der Simulation als auch noch bestehende Schwächen der Modelle selbst sind als Ursache hierfür in Betracht zu ziehen. Darauf weist auch die Tatsache hin, dass einige der experimentell beobachteten Phänomene bisher mit keinem der beiden Modelle simuliert werden konnte.

description: We present a detailed study of the (pseudo)rapidity distributions of massive vector bosons produced in p+p and p+Pb collisions at the LHC within the next-to-leading order approximation in perturbative quantum chromodynamics. In particular, we discuss the impact of different cold nuclear matter effects on this process using the nuclear parton distributions calculated from the microscopic model developed by Kulagin and Petti (KP). This model was successfully applied to study nuclear effects in the deep-inelastic scattering and the Drell-Yan reactions off various (fixed) target nuclei. Results are compared with the recent CMS and ATLAS p+Pb data with \sqrt{s}=5.02 TeV per two colliding nucleons. We found an excellent agreement between the predictions of the KP model and the recent LHC data on W+- and Z0 production in p+Pb collisions, including the differential cross sections, the forward-backward asymmetries, and W charge asymmetry. We also discuss the sensitivity of the current and future LHC data to the underlying mechanisms responsible for the nuclear modifications of parton density functions.

description: Es wird die Synthese primärer Amine durch Hydroaminomethylierung bzw. reduktive Aminierung mit Ammoniak und dessen Äquivalenten untersucht. Bei der rhodiumkatalysierten Hydroaminomethylierung von Monoolefinen und bei der reduktiven Aminierung von Aldehyden mit Ammoniak wird i.Allg. das entsprechende sekundäre Amin als Hauptprodukt gebildet. Um dies zu erklären, wird ein allgemeiner Mechanismus aufgestellt, anhand dessen die Versuchsergebnisse erklärt werden. Mit Cyclohexen als Modellolefin kann gezeigt werden, dass eine möglichst geringe Temperatur und ein niedriger Wasserstoffpartialdruck gewählt werden müssen, um hohe Anteile am primären Amin zu erreichen. Mit Iridium als Cokatalysator werden dagegen hohe Temperaturen und ein hoher Wasserstoffpartialdruck benötigt. Bei der heterogen katalysierten reduktiven Aminierung von Cyclohexancarbaldehyd werden die besten Ergebnisse mit desaktivierten Palladiumkatalysatoren erreicht. Die selektive Synthese von Cyclohexylmethylamin gelingt schließlich mit Raney Cobalt bzw. auf Kieselgel abgeschiedenem Cobalt mit Ammoniumacetat in Methanol (10 % NH3(aq)). Mit Harnstoff als Ammoniakäquivalent werden durch Hydroaminomethylierung selektiv symmetrische tertiäre Amine in hohen Ausbeuten, oder als Nebenprodukt 1,3-bisalkylierte Harnstoffe erhalten. Auch diese Befunde werden anhand eines Mechanismus erklärt. Ausgehend von geschützten Aminoolefinen werden zahlreiche Polyamine und Polyaminoalkohole in hohen Ausbeuten hergestellt. Durch in situ Eliminierung werden Alkohole als Vorstufe für Olefine zur Hydroaminomethylierung eingesetzt.

The arrow of time in open quantum systems and dynamical breaking of the resonance-antiresonance symmetry

description: Open quantum systems are often represented by non-Hermitian effective Hamiltonians that have complex eigenvalues associated with resonances. In previous work we showed that the evolution of tight-binding open systems can be represented by an explicitly time-reversal symmetric expansion involving all the discrete eigenstates of the effective Hamiltonian. These eigenstates include complex-conjugate pairs of resonant and anti-resonant states. An initially time-reversal-symmetric state contains equal contributions from the resonant and anti-resonant states. Here we show that as the state evolves in time, the symmetry between the resonant and anti-resonant states is automatically broken, with resonant states becoming dominant for $t>0$ and anti-resonant states becoming dominant for $t<0$. Further, we show that there is a time-scale for this symmetry-breaking, which we associate with the "Zeno time." We also compare the time-reversal symmetric expansion with an asymmetric expansion used previously by several researchers. We show how the present time-reversal symmetric expansion bypasses the non-Hilbert nature of the resonant and anti-resonant states, which previously introduced exponential divergences into the asymmetric expansion.

description: Understanding physical configurations and how these can emerge from the underlying gauge theory is a fundamental problem in modern particle physics. This thesis investigates the study of these configurations primarily focussing on the need for gauge invariance in constructing the gauge invariant fields for any physical theory. We consider Wu’s approach to gauge invariance by identifying the gauge symmetry preserving conditions in quantum electrodynamics and demonstrate how Wu’s conditions for one-loop order calculations (under various regularisation schemes) leads to the maintenance of gauge invariance. The need for gauge invariance is stressed and the consequences discussed in terms of the Ward identities for which various examples and proofs are presented in this thesis. We next consider Zwanziger’s description of a mass term in Yang-Mills theory, where an expansion is introduced in terms of the quadratic and cubic powers of the field strength. Although Zwanziger introduced this expansion there is, however, no derivation or discussion about how it arises and how it may be extended to higher orders. We show how Zwanziger’s expansion in terms of the inverse covariant Laplacian can be derived and extended to higher orders. An explicit derivation is presented, for the first time, for the next to next to leading order term. The role of dressings and their factorisation lies at the heart of this analysis.

description: Aims: To examine the effectiveness of PREP (Pathways and Resources for Engagement and Participation) knowledge translation (KT)-program on (a) change in practice behaviors and improved knowledge of school-based occupational therapists, and (b) participation of children with disabilities in inclusive education. Methods: A mixed-methods design was employed. Therapists (n = 39) completed a 30-hour program. Each therapist applied PREP intervention to one child (n = 39) aged 4-15 (Mean = 9.31, SD = 2.4). Therapists’ outcomes included: (a) knowledge of PREP evaluated using a clinical vignette, analyzed descriptively, (b) change in practice behavior measured by the Professional Evaluation and Reflection on Change Tool (PERFECT), analyzed thematically. Change in children’ participation pre- and post-KT-program and during follow-up was measured by the Canadian Occupational Performance Measure (COPM), analyzed using ANOVA. Results: Therapists acquired knowledge of PREP (vignette mean score 17.7/20). PERFECT revealed therapists’ self-perceived changes in practice: incorporating an environmental perspective, expanding partnerships, and redirecting focus on participation. Completing the KT-program was a primary enabler and reason for change. Children’s participation significantly improved post KT-program and during follow-up in both performance (p < 0.001) and satisfaction (p < 0.001). Conclusions. KT strategies, as illustrated in this study, accelerated the uptake of evidence-based interventions, minimizing existing ’know-do' gaps and promoting children’s health through participation.
