description: Context: The recent detection of very high-energy (VHE) gamma-ray emission from the direction of the W43 star-forming region prompted us to investigate its stellar population in detail in an attempt to see wether or not it is possible an association. Aims: We search for the possible counterpart(s) of the gamma-ray source or any hints of them, such as non-thermal synchrotron emission as a tracer of relativistic particles often involved in plausible physical scenarios for VHE emission. Methods: We data-mined several archival databases with different degrees of success. The most significant results came from radio and near-infrared archival data. Results: The previously known Wolf-Rayet star in the W43 central cluster and another cluster member appear to be resolved into two components,suggesting a likely binary nature. In addition, extended radio emission with a clearly negative spectral index is detected in coincidence with the W43 cluster. These findings could have important implications for possible gamma-ray emitting scenarios, which we also briefly discuss.

description: International health electives pose specific ethical challenges for students travelling from to low and middle income countries. We undertook a systematic review of the literature on interventions to prepare students to identify ethical issues addressed, educational approaches and to collate evidence on the effectiveness of different strategies. We searched nine electronic databases of peer-reviewed literature and identified grey literature through key word searches; supplemented through citation mapping and expert consultation. Articles that described ethical training conducted by universities or professional bodies were included for review. We reviewed forty-four full text articles. Ten sources of published literature and seven sources of grey literature met our inclusion criteria. We identified thirteen ethical situations that students should be prepared to manage and eight generic skills to support this process. Most interventions were delivered before the elective, used case studies or guidelines. Some suggested ethical principles or a framework for analysis of ethical issues. Only two papers evaluated the intervention described. Our paper collates a small but growing body of work on education to prepare students to manage ethical issues. Ethical training should have elements that are delivered before, during and after the elective. Interventions should include case studies covering thirteen ethical issues identified here, linked to ethical principles and a process for responding to ethical issues. We suggest that evaluations of interventions are an important area for future research.

description: The Christian's act of faith, though not necessarily following upon demonstrable proofs, nevertheless may be said to be rational in that it is grounded on and responsive to a personal, experiential, preconceptual cognition or apprehension of the divine which gives rise to and justifies belief formulations. Such formulations, expressing personal knowledge and assent are, however, valid only in the context of the larger revelation which is expressed in the Judaeo­Christian scriptures and embodied in and interpreted by the doctrinal tradition of the Christian community. The position argued by this Thesis is consonant with the central Christian tradition of faith seeking understanding. It emphasises the supernatural dimension in viewing all the elements of the act as integrated within a grace-given relationship with God, and is supported by aspects of the thought of Saint Thomas Aquinas, John Henry Newman and Bernard Lonergan.

description: We carry out several isolated galaxy evolution simulations in a fixed dark matter halo gravitational potential using the new version of our N-body/Smoothed Particle Hydrodynamics (SPH) code GCD+. The new code allows us to more accurately model and follow the evolution of the gas and stellar components of the system including powerful supernovae feedback and its effects on the inter-stellar medium (ISM). Here we present the results of six simulations of an M33-sized late-type disc galaxy each with varying values for our model parameters which include the star formation efficiency (C*), the energy released per supernovae explosion (E_SN) and the energy released per unit time from stellar winds (E_SW). We carry out both a pixel-by-pixel and radial ring analysis method for each of our galaxies comparing our results to the observed Schmidt-Kennicutt Law and vertical gas velocity dispersion versus radius relation amongst others. We find that our models with higher feedback more closely resemble the observations and that feedback plays a pivotal role in obtaining both the observed Schmidt-Kennicutt and gas velocity dispersion relations.

The Dynamical State of Dark Matter Haloes in Cosmological Simulations I: Correlations with Mass Assembly History

description: Using a statistical sample of dark matter haloes drawn from a suite of cosmological N-body simulations of the Cold Dark Matter (CDM) model, we quantify the impact of a simulated halo's mass accretion and merging history on two commonly used measures of its dynamical state, the virial ratio eta and the centre of mass offset Delta r. Quantifying this relationship is important because the degree to which a halo is dynamically equilibrated will influence the reliability with which we can measure characteristic equilibrium properties of the structure and kinematics of a population of haloes. We begin by verifying that a halo's formation redshift zform correlates with its virial mass Mvir and we show that the fraction of its recently accreted mass and the likelihood of it having experienced a recent major merger increases with increasing Mvir and decreasing zform. We then show that both eta and Delta r increase with increasing Mvir and decreasing zform, which implies that massive recently formed haloes are more likely to be dynamically unrelaxed than their less massive and older counterparts. Our analysis shows that both eta and Delta r are good indicators of a halo's dynamical state, showing strong positive correlations with recent mass accretion and merging activity, but we argue that Delta r provides a more robust and better defined measure of dynamical state for use in cosmological N-body simulations at z~0. We find that Delta r < 0.04 is sufficient to pick out dynamically relaxed haloes at z=0. Finally, we assess our results in the context of previous studies, and consider their observational implications.

description: We present the energy eigenvalues of a quantum bouncer in the framework of the Generalized (Gravitational) Uncertainty Principle (GUP) via quantum mechanical and semiclassical schemes. In this paper, we use two equivalent nonperturbative representations of a deformed commutation relation in the form [X,P]=i\hbar(1+βP^2) where βis the GUP parameter. The new representation is formally self-adjoint and preserves the ordinary nature of the position operator. We show that both representations result in the same modified semiclassical energy spectrum and agrees well with the quantum mechanical description.

One of the main objectives of this work has been the documentation of the archaeology of Mound J. The discovery, excavation and restoration of this structure are discussed in the first two chapters of this work. The other main goals, the identification, reproduction and interpretation of some aspects of the iconographic and hieroglyphic material found in some of the slabs associated with this structure, occupy the rest of this thesis. Classic interpretations are discussed together with new theories on the meaning and possible motifs from which certain iconographic elements may have originated.

description: We describe a cost-effective methodology for obtaining loadings for the environmentally significant chemical species of silicate, nitrate, nitrite, ammonium, and orthophosphate through the Hillsboro and Boca Raton inlets (Florida, USA). Field measurements included 'grab' water samples obtained from each inlet during an 18-month period and four ebb tide sampling intensives conducted at both inlets. During sampling intensives, water currents were measured from a small boat using a downward-looking acoustic Doppler current profiler, and water samples were collected for analysis. Loadings were computed from the sampling intensives data and estimated for the entire period using flow estimates generated from tidal range data. These data are presented as monthly loadings from each inlet.

The microscopic changes which the black hole undergoes are interpreted using the AdS/CFT correspondence. Using particle absorption phenomena, we formulate an irreducible mass and black hole entropy directly related to the particle momenta. We describe the black hole evolution that preserves the 2nd law of thermodynamics. The numbers of microstates which evaluate the entropy are analyzed at each of the black hole evolution stages.

description: Both experimental and theoretical studies are carried out to investigate the behaviour of concrete flat plates subjected to shear and reversed cyclic moment at their connections. Tests of seven full-size interior slab-column connections subjected to shear and cyclic horizontal load are reported. Based on the test results in this study and previous test results published in the literature, it is concluded that the slab-column connections with shear studrails in the column vicinity posses enough ductility to meet the requirements of the current seismic design codes, such as the National Building Code of Canada (1990) and the Uniform Building Code (1988). It is also observed in the tests and concluded from the analysis that the strength of the slab-column connections under cyclic load is about 20% less than that of the connections under monotonic load. For the flexural strength design of the connections, a fonnula based on the yield-line theory is developed. Some suggestions for improving the connection behaviour under cyclic loading are made.

We review the history of this exact solution and discuss recent developments related to the Richardson-Gaudin class of integrable models, focussing on the role of these various models in nuclear physics.

description: Fibroadenomas are the most common breast tumor in adolescents and young women.They comprise  20% of benign breast masses and 12% of all breast masses in postmenopausal women. Smooth muscle metaplasia and adipose differentiation are uncommon forms of stromal differentiation encountered in a minority of fibroadenomas. Liposarcoma can arise from pre-existing benign lesions like phylloides tumour or from lipoid tissue in the breast. In this article we present a case of 38 year-old female who presented with a right breast mass which was clinically diagnosed as a case of fibroadenoma, but histologically showed a low grade well-circumscribed liposarcoma discovered in a pericanalicular type of fibroadenoma with stromal adipose differentiation. According to our knowledge, this the first case of a well-circumscribed liposarcoma arises in fibroadenoma of the breast.

title: Infrared Spectroscopic Techniques & Predictive Modelling Applied to Oral Cancer Diagnostics
Creators: name: Ellis, Barnaby
Publisher: name: University of Liverpool Repository
Year: 2022

description: Cancer is a leading cause of mortality and morbidity worldwide. The burden cancer imposes on health services is increasing, owing to an ageing and growing population. Whilst effective treatment is essential, the prevention, diagnosis and risk stratification of early-stage cancer is paramount. Subjectivity and ambiguity are a hindrance in the diagnosis of many cancers. Oral cancer is a condition that is often diagnosed at a late stage as asymptotic early-stage conditions regularly go undetected. Vibrational spectroscopy is a family of techniques which allow an objective view of the intrinsic chemistry of a sample. It has shown great promise in the field of cancer diagnosis, but there is still a significant gulf between research efforts and clinical adoption. The work contained within this thesis describes the utilisation of novel vibrational spectroscopy analytical methods to extract important information from pathological oral tissue. The important information is used to provide further insight into the biochemistry of malignancy, as well as to attempt to predict malignant transformation in early-stage cancer.

The Lyapunov Indicator (LI); the Mean Exponential Growth factor of Nearby Orbits (MEGNO); the Smaller Alignment Index (SALI); the Fast Lyapunov Indicator (FLI); the Dynamical Spectra of stretching numbers (SSN) and the corresponding Spectral Distance (D); and the Relative Lyapunov Indicator (RLI), which is based on the evolution of the difference between two close orbits, have been included. The experiments presented herein allow us to reliably suggest a group of chaos indicators to analyze a general mapping. We show that a package composed of the FLI and the RLI (to analyze the phase portrait globally) and the MEGNO and the SALI (to analyze orbits individually) is good enough to make a description of the systems' dynamics.

description: Primary neuroendocrine tumor of the breast is a rare condition. Although 20-30% of primary breast cancers show neuroendocrine differentiation to some degree, according to the WHO classification, at least 50% of the tumor cells have to be positive with at least one neuroendocrine immunohistochemical marker to establish a diagnosis of neuroendocrine tumor of the breast while clinically excluding other primary sites and a metastatic nature. Due to the low prevalence of this disease our understanding of its development, prognosis and effective therapy is limited. Up to date there are 125 cases reported in the English and non-English literature, now including our own case as well. We report a case of a 75 years old female. The patient presented with a 2 cm large mobile nodule in the upper outer quadrant of the left breast. Lumpectomy was performed based on fine needle aspiration cytology with a positive result showing malignant proliferation. Examination of the surgical specimens revealed neuroendocrine differentiation in approximately 90% of the tumor cells. Immunohistochemical studies and additional imaging studies revealed no other primary.

description: Sequential Monte Carlo (SMC), or particle filtering, is widely used in nonlinear state-space systems, but its performance often suffers from poorly approximated proposal and state-transition distributions. This work introduces a differentiable particle filter that leverages the unsupervised variational SMC objective to parameterize the proposal and transition distributions with a neural network, designed to learn from high-dimensional observations. Experimental results demonstrate that our approach outperforms established baselines in tracking the challenging Lorenz attractor from high-dimensional and partial observations. Furthermore, an evidence lower bound based evaluation indicates that our method offers a more accurate representation of the posterior distribution.

description: A novel explanation of observed enhanced longitudinal mode spacing in InGaN semiconductor lasers has been proposed. It has been demonstrated that e-h plasma oscillations, which can exist in the laser active layer at certain driving conditions, are responsible for mode clustering effect. The resonant excitation of the plasma oscillations occurs due to longitudinal mode beating. The separation of mode clusters is typically by an order of magnitude larger that the individual mode spacing.

description: We generalize the concept of the symmetric hyperdeterminants for symmetric tensors to the E-determinants for general tensors. We show that the E-determinant inherits many properties of the determinant of a matrix. These properties include: solvability of polynomial systems, the E-determinat of the composition of tensors, product formula for the E-determinant of a block tensor, Hadamard's inequality, Gersgrin's inequality and Minikowski's inequality. As a simple application, we show that if the leading coefficient tensor of a polynomial system is a triangular tensor with nonzero diagonal elements, then the system definitely has a solution. We investigate the characteristic polynomial of a tensor through the E-determinant. Explicit formulae for the coefficients of the characteristic polynomial are given when the dimension is two.

description: We study interacting 1D two-component mixtures of cold atoms in a random potential, and extend the results reported earlier [{\it Phys. Rev. Lett.} {\bf 105}, 115301 (2010)]. We construct the phase diagram of a disordered Bose-Fermi mixture as a function of the strength of the Bose-Bose and Bose-Fermi interactions, and the ratio of the bosonic sound velocity and the Fermi velocity. Performing renormalization group and variational calculations, three phases are identified: (i) a fully delocalized two-component Luttinger liquid with superfluid bosons and fermions (ii) a fully localized phase with both components pinned by disorder, and (iii) an intermediate phase where fermions are localized but bosons are superfluid. Within the variational approach, each phase corresponds to a different level of replica symmetry breaking. In the fully localized phase we find that the bosonic and fermionic localization lengths can largely differ. We also compute the momentum distribution as well as the structure factor of the atoms (both experimentally accessible), and discuss how the three phases can be experimentally distinguished.

description: We report on the systematic characterization of conductive micro-channels fabricated in single-crystal diamond with direct ion microbeam writing. Focused high-energy (~MeV) helium ions are employed to selectively convert diamond with micrometric spatial accuracy to a stable graphitic phase upon thermal annealing, due to the induced structural damage occurring at the end-of-range. A variable-thickness mask allows the accurate modulation of the depth at which the microchannels are formed, from several μm deep up to the very surface of the sample. By means of cross-sectional transmission electron microscopy (TEM) we demonstrate that the technique allows the direct writing of amorphous (and graphitic, upon suitable thermal annealing) microstructures extending within the insulating diamond matrix in the three spatial directions, and in particular that buried channels embedded in a highly insulating matrix emerge and electrically connect to the sample surface at specific locations. Moreover, by means of electrical characterization both at room temperature and variable temperature, we investigate the conductivity and the charge-transport mechanisms of microchannels obtained by implantation at different ion fluences and after subsequent thermal processes, demonstrating that upon high-temperature annealing, the channels implanted above a critical damage density convert to a stable graphitic phase. These structures have significant impact for different applications, such as compact ionizing radiation detectors, dosimeters, bio-sensors and more generally diamond-based devices with buried three-dimensional all-carbon electrodes.

Subjects: subject: 658 Allgemeines Management

description: This master’s thesis explores product ownership within the context of software development projects, primarily focusing on identifying key personality traits essential for effective product ownership. The research question is: "What are the key personality traits associated with effective product ownership depending on the type of software development project?". Critical insights were discovered through comprehensive literature research regarding the fundamental traits that distinguish an effective product owner. This research analyzes existing personality traits and their relevance to product ownership. In addition to the widely recognized Big Five personality traits, the research identified the significance of emotional intelligence, openness to experience, conscientiousness, agreeableness, and self-efficacy, providing a holistic perspective of the multifaceted product owner role. A distinctive facet of this thesis lies in its ability to contextualize the personality traits of various software development project types. Five specific project types - custom software development, product development, legacy system modernization, maintenance, and integration projects - were identified, and the thesis explains how these projects demand distinct combinations of personality traits for success. Furthermore, this research provides the practical tool (artifact), the "Product Owner: Key Personality Traits Guideline", and it is designed to empower hiring managers, team leads, and department heads with a structured framework for evaluating the personality traits of product owner candidates and matching them with the unique requirements of their projects. This thesis contributes to the literature and practical application in the software development industry. By offering an improved understanding of the product-owner role and its various demands, this thesis provides a strategic approach to hiring and project placement, ultimately enhancing the likelihood of project success. While it achieves significant milestones, it also identifies potential for future research, including a quantitative exploration to solidify qualitative findings further. This thesis contributes towards more effective product ownership and tries to influence practices within software development.

description: Phoenix sylvestris (Arecaceae family) known as Indian Date Palm has been identified as a component of traditional medicine against various ailments. The present study was focused on phytochemical screening of crude hexane, dichloromethane and methanol leaf extracts. The crude extracts showed the presence of alkaloids, flavonoids, and phenols in the plant leaves. In the study methanol extract was found most potent, so this extract was further fractionated by column chromatography and 9 methanol purified fractions (MPFs) were isolated. Most potential MPF8 (20:80 chloroform: methanol ratio fraction) significantly enhanced free radicals and antibacterial activity. The best MIC (Minimum inhibitory concentration) of MPF8 was investigated against M. luteus and E. coli at 1 mg/ml concentration. However, against other bacteria the MIC ranged from 1 mg/ml to 3 mg/ml. The GC-MS analysis showed the presence of many biologically active compounds such as alcohols, flavonoids, aromatic compounds, aldehydes, terpenoids fatty acid methyl esters, and phenolics. Pentadecanoic acid occupied maximum (52 %) area in GC-MS profiling. MPF8 was assayed for in-vitro cytotoxicity by MTT assay which confirms its less cytotoxicity at lower concentration and also significant ROS determination against J774 and THP1 cell lines after 2 and 4 hours.

description: In a joint decision between stakeholders from research (TU Dortmund University) and clinical practice (Neurological Rehabilitation Center Godeshoehe, Bonn), and considering evidence from the literature, fatigue was identified as a serious and common symptom in persons with multiple sclerosis (pwMS), where exercise might be applied as an efficacious intervention. Therefore, research efforts were directed at the development of an exercise-based fatigue intervention. In summary, publication 1 supported that aerobic training is not the most efficacious exercise type to reduce fatigue in pwMS. Publications 2-5 then developed a new group-based multimodal agility-based exercise training (MAT) framework centered on previously described working mechanisms regarding exercise and fatigue, and quantitatively and qualitatively evaluated the feasibility of conducting a randomized-controlled trial in a clinical inpatient rehabilitation setting to compare the new framework (MAT) with traditional strength and endurance training. Results showed that several changes need to be applied before the evaluation of the study protocol can be continued. Consequently, research can build on these early stage, but important results in the future.

description: Several studies have been in favor of fungi as a possible pathogenesis of chronic rhinosinusitis (CRS); however, to date, there is no scientific consensus about the use of antifungal agents in disease management. The aim of the present study was to investigate the efficacy of intranasal fluconazole in improving disease symptoms and objective outcomes of patients with CRS. A randomized, double-blind, placebo-controlled study was conducted on 54 patients who were diagnosed with CRS and had not been responsive to routine medical treatments. They were randomly assigned to receive either fluconazole nasal drop 0.2 % or placebo in addition to the standard regimen for a duration of 8 weeks. Patients' outcomes were evaluated according to Sino-Nasal Outcome Test 20 (SNOT-20), endoscopic scores, and Computed Tomography (CT) scores. No statistically significant difference was found in SNOT-20 (p = 0.201), endoscopic (p = 0.283), and CT scores (p = 0.212) of the patients at baseline and after 8-week course of treatment between drug and placebo group. Similar to many studies, the use of topical antifungal treatment for patients with CRS was not shown to be significantly effective. However, further studies are needed to obtain high levels of consistent evidence in order to arrive at a decision whether antifungal therapy is effective in management of CRS or not.
