Subjects: Uncategorized

description: Throughout the history of mankind, we have sought ways and means to extend the boundaries of our sensory system with the help of science and technology. Active sensing systems have played a vital role in the advancement of human civilization--- in navigation, communication, system identification, defense, energy cultivation, meteorology, space exploration, etc It is well known that a judicious design of the transmit signals improves the performance of an active sensing system by enhancing the target detection and estimation capability by manyfold. This thesis is concerned with synthesizing waveforms for smart active sensing systems of forthcoming decades, viz, (i) improved system identification and (ii) advanced radar systems. Several problems of signal optimization in the context of practical scenarios have been considered. The associated problems are studied and several novel algorithms are proposed and supported by several numerical examples.
title: INVESTIGATION OF HOST NANOTUBE PARAMETERS FOR ENHANCING THE PERFORMANCE OF NANOSTRUCTURED CDS-CDTE SOLAR CELLS
Creators: name: Kumar, Deepak
Publisher: name: University of Kentucky Libraries
Year: 2020

description: Numerical simulations are performed to investigate the effects of host nanotube parameters (pore diameter and pitch for different CdS coverages) and CdTe doping density on device performance in nanowire CdS/ CdTe solar cells using SCAPS-1D. This research finds the optimum values for these parameters in order to achieve the highest efficiency. Experimentally the effect of anodization voltage and fluoride ion concentration on the pore diameter and the pitch are studied for the Titania nanotubes host. It is observed that in the range of 0.3 mL to 2 mL of ammonium fluoride content, pore diameter and the pitch of the Titania nanotube host matrix, fabricated in ethylene glycol-based electrolyte, is rather insensitive to the ammonium fluoride concentration. It is also shown that anodization voltage is the more effective parameter, which can be tailored and optimized to fabricate Titania Nanotube arrays of desired porosity. The bulk series resistance of the device, in addition to the CdTe doping density, varies upon varying the pore diameter and the pitch of the nanotubes for various fractions of CdS coverages. In this work, theoretical absorption profile was interpolated using the experimentally obtained absorption spectrum for various fractions of CdS coverages. The highest efficiency for this NW-CdS/CdTe solar cell structure at 300°K was found to be 25.93% with short circuit current of 28.3 mA cm-2, open circuit voltage of 1.11 V and fill factor of 0.825; this was obtained when the pore diameter and the pitch of the host nanotube was in the range of 2.35nm – 23.48nm and 100nm – 1000nm respectively and the CdTe doping density was 1017 cm-3. Thus, it is shown that the host nanotube parameters (pore diameter and pitch for different CdS coverages) and CdTe doping density can be tailored to give optimum device performance.

Analysis of building vulnerability and firebrand exposure to mitigate wildfire damage
Creators: name: Dossi, Simona
Publisher: name: Imperial College London
Year: 2023

description: Wildfire intensity and resulting damage to communities and infrastructure is increasing worldwide; this thesis investigates the vulnerability of wildland-urban interface (WUI) buildings to wildfires, focusing on firebrand exposure. The research objective is to improve understanding of wildfire damage mechanisms to aid effective risk reduction practices. A comprehensive literature review establishes the need for quantitative building vulnerability assessments and advanced understanding of firebrand deposition and accumulation around solid obstacles. To address these needs, a statistical analysis on two large wildfire damage databases from Portugal and California is conducted to investigate the relationship between building design and damage extent. The results contribute to the development of a preliminary building resistance index (WRI) to assess building vulnerability to wildfire damage. The thesis progresses to characterise the feasibility of using the Fire Dynamics Simulator (FDS) to simulate firebrand creep movement and accumulation around solid obstacles. A sensitivity analysis quantifies the impact of input parameters on final particle position, revealing a relationship between sensitivity and the Tachikawa number, which describes the aerodynamic properties of simulated particles. A comparison between two FDS Lagrangian Particle model modalities assesses their efficacy in simulating firebrand accumulation based on previously published experimental results. The analysis explain the connection between particulate transport physical mechanisms and the effective operational FDS use for simulating wildfire firebrand exposure. FDS simulations are subsequently conducted to identify regions of firebrand contact exposure, connected to firebrand ignition hazard, around three different obstacles mimicking common building components. Results characterize the combined influence of wind speed and obstacle geometry on firebrand contact exposure. Finally, the applicability of established sand protection measures to protect infrastructure from firebrands is explored by reviewing literature and conducting exploratory FDS simulations. The effectiveness of a trench protection measure to inhibit firebrand accumulation on an infrastructure component is investigated, indicating its potential when combined with contextual information on infrastructure design and ambient conditions.

description: The Virgo cluster of galaxies provides excellent conditions for studying interactions of galaxies with the cluster environment. Both the high-velocity tidal interactions and effects of ram pressure stripping by the intracluster gas can be investigated in detail. We extend our systematic search for possible anomalies in the magnetic field structures of Virgo cluster spirals in order to characterize a variety of effects and attribute them to different disturbing agents. Six angularly large Virgo cluster spiral galaxies (NGC4192, NGC4302, NGC4303, NGC4321, NGC4388, and NGC4535) were targets of a sensitive total power and polarization study using the 100-m radio telescope in Effelsberg at 4.85GHz and 8.35GHz (except for NGC4388 observed only at 4.85GHz, and NGC4535 observed only at 8.35GHz). Magnetic field structures distorted to various extent are found in all galaxies. Three galaxies (NGC4302, NGC4303, and NGC4321) show some signs of possible tidal interactions, while NGC4388 and NGC4535 have very likely experienced strong ram-pressure and shearing effects, respectively, visible as distortions and asymmetries of polarized intensity distributions. As in our previous study, even strongly perturbed galaxies closely follow the radio-far-infrared correlation. In NGC4303 and NGC4321, we observe symmetric spiral patterns of the magnetic field and in NGC4535 an asymmetric pattern. Magnetic fields allow us to trace even weak interactions that are difficult to detect with other observations. Our results show that the degree of distortions of a galaxy is not a simple function of the distance to the cluster center but reflects also the history of its interactions. The angle between the velocity vector and the rotation vector of a galaxy may be a general parameter that describes the level of distortions of galactic magnetic fields.

description: We present 15-GHz follow-up radio observations of eleven Swift gamma-ray burst (GRB) sources, obtained with the Arcminute Microkelvin Imager Large Array (AMI-LA). The initial follow-up observation for each source was made in a fully automated fashion; as a result four observations were initiated within five minutes of the GRB alert timestamp. These observations provide the first millijansky-level constraints on prolonged radio emission from GRBs within the first hour post-burst. While no radio emission within the first six hours after the GRB is detected in this preliminary analysis, radio afterglow is detected from one of the GRBs (GRB120326A) on a timescale of days. The observations were made as part of an ongoing programme to use AMI-LA as a systematic follow-up tool for transients at radio frequencies. In addition to the preliminary results, we explain how we have created an easily extensible automated follow-up system, describing new software tools developed for astronomical transient alert distribution, automatic requesting of target-of-opportunity observations, and robotic control of the observatory.

description: Power laws are theoretically interesting probability distributions that are also frequently used to describe empirical data. In recent years effective statistical methods for fitting power laws have been developed, but appropriate use of these techniques requires significant programming and statistical insight. In order to greatly decrease the barriers to using good statistical methods for fitting power law distributions, we developed the powerlaw Python package. This software package provides easy commands for basic fitting and statistical analysis of distributions. Notably, it also seeks to support a variety of user needs by being exhaustive in the options available to the user. The source code is publicly available and easily extensible.

Year: 2014

description:
This study examined the efficacy of an intensive stuttering therapy program that was highly structured and based on neuroplasticity and the principles of motor learning. Treatment sessions were conducted in person and through Skype 4 days a week for a total of 8 weeks. Speech samples were collected throughout the study during Skype testing sessions and through self-recordings by the participants. These samples were analyzed for percent stuttered syllables and naturalness rating. Outcome measures also included a series of self-ratings by the participants and the completion of selected sections of the Overall Assessment of the Speaker's Experience of Stuttering (OASES). Results indicated that the participants' levels of disfluency and self-ratings improved throughout the course of the study. Individual differences in response to treatment are discussed.

description: The statistics of Lagrangian pair dispersion in a homogeneous isotropic flow is investigated by means of direct numerical simulations. The focus is on deviations from Richardson eddy-diffusivity model and in particular on the strong fluctuations experienced by tracers. Evidence is obtained that the distribution of distances attains an almost self-similar regime characterized by a very weak intermittency. The timescale of convergence to this behavior is found to be given by the kinetic energy dissipation time measured at the scale of the initial separation. Conversely the velocity differences between tracers are displaying a strongly anomalous behavior whose scaling properties are very close to that of Lagrangian structure functions. These violent fluctuations are interpreted geometrically and are shown to be responsible for a long-term memory of the initial separation. Despite this strong intermittency, it is found that the mixed moment defined by the ratio between the cube of the longitudinal velocity difference and the distance attains a statistically stationary regime on very short timescales. These results are brought together to address the question of violent events in the distribution of distances. It is found that distances much larger than the average are reached by pairs that have always separated faster since the initial time. They contribute a stretched exponential behavior in the tail of the inter-tracer distance probability distribution. The tail approaches a pure exponential at large times, contradicting Richardson diffusive approach. At the same time, the distance distribution displays a time-dependent power-law behavior at very small values, which is interpreted in terms of fractal geometry. It is argued and demonstrated numerically that the exponent converges to one at large time, again in conflict with Richardson's distribution.

title: Deoxygenation properties of Ru-based phosphide catalysts
Creators: name: Carrillo, Bo
Publisher: name: Western Washington University
Year: 2014

description:
Bio-oil derived from fast pyrolysis of bio-mass is becoming a more viable option for addressing the growing demand for oil while being more environmentally friendly than fossil fuels. However, bio-oils have poor chemical stability and high acidity due to their high oxygen content. Metal phosphides such as ruthenium phosphide (Ru2P) have been investigated by the Bussell group to catalytically upgrade compounds contained in bio-oil, but further optimization is required before their commercial viability can be accessed. In current research, less expensive, more abundant metals (Co or Ni) are being used to replace some of the ruthenium, which is both expensive and rare. Cobalt-ruthenium phosphides (CoxRu2-xP, 0 ≤ x ≤ 2) and nickel-ruthenium phosphides (NixRu2-xP, 0 ≤ x ≤ 2) supported on silica at a fixed P/M molar ratio (M = Co + Ru or Ni + Ru) of 0.72 were prepared from hypophosphite-based precursors and their properties for furan deoxygenation were investigated. The deoxygenation properties of the Co-Ru and Ni-Ru phosphides were compared with those of Co-Ru/SiO2 and Ni-Ru/SiO2 catalysts having the same metal composition as well as an industrial Co-Mo/Al2O3 hydrotreating catalyst. The deoxygenation activities were observed to be strongly influenced by the metal content of the catalysts with the highest activity observed for M-rich MxRu2-xP/SiO2 catalysts, suggesting a synergistic effect as their deoxygenation activities were significantly higher than either Ru2P/SiO2 or M2P/SiO2. The product selectivities of the metal phosphide (e.g. Co1.00Ru1.00P/SiO2) and metal catalysts (e.g. Co1.00Ru1.00/SiO2) differed significantly. The metal phosphides showed a much higher selectivity for C3 hydrocarbons, while the metal catalysts showed high selectivity towards methane. The observed trends in deoxygenation activity and selectivity of the metal phosphide catalysts will be discussed.
A hyperbolic perspective on the Dehn surgery characterisation problem
Creators: name: Wakelin, Laura
Publisher: name: Imperial College London
Year: 2023

description: As is the case for many questions in low-dimensional topology, the Dehn surgery characterisation problem is simple to state but difficult to solve. Given a non-trivial slope p/q, when does the oriented homeomorphism type of the 3-manifold obtained by Dehn surgery of slope p/q on a knot K in the 3-sphere uniquely characterise the knot K? A wide variety of techniques, ranging from Floer homology to more geometric approaches, have been successfully employed to find characterising slopes for certain knots; the construction of non-characterising slopes has also been studied extensively. However, there is currently no universal criterion to determine whether a slope is characterising or non-characterising for any given knot. This thesis investigates the Dehn surgery characterisation problem in the case where the knot complement has a hyperbolic outermost JSJ piece. The fundamental strategy involves comparing JSJ decompositions before and after Dehn filling: this allows us to reduce the problem at hand to one about hyperbolic geometry. Subsequently, two novel ideas - minimal geodesics (in the more general case) and minimal volumes (in the special case of Whitehead doubles) - can be used to determine explicit conditions which ensure that a slope is characterising. The limitations of this method are also illustrated via a construction of infinite families of pairs of multiclasped Whitehead doubles sharing a non-characterising slope.

Fox colorings are assignments of labels to arcs, Dehn colorings are assignments of labels to regions, and Alexander-Briggs colorings assign labels to vertices. The labels are found among the integers modulo n. The choice of n depends upon the knot. Each type of coloring rules has an associated rule that must hold at each crossing. For the Alexander Briggs colorings, the rules hold around regions. The relationships among the colorings is explained.

The implementation of care pathways to improve children’s allergy services
Creators: name: Spitters, Sophie
Publisher: name: Imperial College London
Year: 2023

description: National reviews demonstrate quality deficiencies in UK health services for allergic children. In response, the RCPCH developed care pathways to improve the organisation and delivery of allergy care. However, care pathway interventions have variable success. Consequently, a literature review and four ethnographic case studies were conducted to theorise care pathway implementation and inform practical recommendations for health service improvements. This process followed the four stages of MELD dialectic: First Moment (1M) of (non-)being, Second Edge (2E) of becoming, Third Level (3L) of integrated totality, and Fourth Dimension (4D) of agency. The 1M results define the mechanisms that cause allergy health service deficiencies and how to address them. Deficiencies were found to emerge from causal mechanisms interacting at physiological, inter-personal, and systemic levels. Care pathway interventions that address these mechanisms could improve the quality of children’s allergy services. However, healthcare improvements also depend on the implementation process and contextual influences. The 2E results describe the unfolding journeys of four teams improving their local health services for allergic children. The 3L results integrate the 1M theoretical understanding and 2E empirical experiences into an advanced understanding of allergy care pathway implementation. The improvement context totality captures contextual factors that manifest differently depending on geohistorical contingencies. This creates unique local challenges and opportunities. The child allergy intervention totality integrates care pathway interventions implemented across case studies. What intervention elements are implemented and to what degree is negotiated based on local challenges and opportunities. The improvement process totality captures the quality improvement methods used to develop interventions and overcome contextual challenges. Children’s allergy health service improvements emerge from the three totalities operating as a dynamic whole. The 4D results discuss the resolution of dialectical contradictions related to the improvement of children’s allergy services. They integrate contradictory theoretical insights identified across academic disciplines by grounding them in the 2L empirical case study experiences and relating them to the 3L structural understanding. These theoretical developments are subsequently translated into practical strategies to navigate and optimise local efforts to improve children’s allergy services. This study used MELD to make theoretical contributions in clinical allergy and improvement science with the aim to support the improvement of children’s allergy services in practice.

Publisher: name: University of Illinois at Chicago

description: Unlike mass media news articles, research papers have a well-defined structure and the language is much more formal. Many words have specific meanings and these meanings do not change based on the context in which these words are used (e.g., repository always designates a kind of storage in a source code control system). We theorize that with a limited manual effort these research papers can be turned into a semantic graph where new relations between terms can be obtained. Moreover, with vocabulary expansion, these terms can be linked to other concepts (e.g., repository -> storage -> memory) thereby enhancing the power of inferential reasoning about new relations. We also explore the possibility of finding contradictions among established relations hence raising new research questions about deeper explorations of already obtained relations. Therefore, in this thesis, we address the problem of automatically creating inferences from the corpus of data published in research papers in the area of empirical software engineering. To this end, we build an MVC-based application called "Generator of Research Output Units in Software Engineering" a.k.a. GROUSE which elicits the user to define relations between terms belonging to the corpus of 603 research papers published across various editions of Mining Software Repositories' conferences. With limited manual effort, we first create a ground truth conceptual graph upon which our application employs techniques such as Expected Entropy Loss (EEL), Latent Semantic Analysis (LSA), Relational Topic Modelling (RTM) and term expansion to infer new relations for semantically similar terms, terms with similar underlying associations and papers which are related depending on the terms they contain. With GROUSE, the empirical software engineering research community can collaborate on automatically generating new research questions that reveal deeper insights into software engineering processes and solutions.

As with the discovery of the charged pion, the recent discovery of a Higgs-like boson may portend a rich new set of particles within reach of current and near future experiments. These may be discovered and studied by cosmic rays through the indirect detection of dark matter.

description: For an oriented surface link $F$ in $\mathbb{R}^4$, we consider a satellite construction of a surface link, called a 2-dimensional braid over $F$, which is in the form of a covering over $F$. We introduce the notion of an $m$-chart on a surface diagram $π(F)\subset \mathbb{R}^3$ of $F$, which is a finite graph on $π(F)$ satisfying certain conditions and is an extended notion of an $m$-chart on a 2-disk presenting a surface braid. A 2-dimensional braid over $F$ is presented by an $m$-chart on $π(F)$. It is known that two surface links are equivalent if and only if their surface diagrams are related by a finite sequence of ambient isotopies of $\mathbb{R}^3$ and local moves called Roseman moves. We show that Roseman moves for surface diagrams with $m$-charts can be well-defined.

A clinicopathological investigation of brainstem nuclei in Lewy body dementia
Creators: name: Patel, Shivani
Publisher: name: Imperial College London
Year: 2023

description: Introduction: Lewy Body Dementias (LBD) - Dementia with Lewy Bodies (DLB) and Parkinson’s Disease Dementia (PDD) - are clinical diagnoses based on the one-year rule and varied symptom onset. Previously, degeneration of the locus coeruleus (LC) and dorsal raphe nucleus (DRN) in LBD has been well established. However, the precise relationship between underlying neuropathology and clinical presentation remains to be determined. Methods: Immunohistochemical and image analysis techniques have been performed to examine neuronal loss and protein pathologies in the noradrenergic and serotonergic systems of 20 PD, 20 PD-MCI, 20 PDD, 20 DLB cases and 20 controls. RNAscope technology was used to decipher the role of cell-surface receptors in LBD pathophysiology. Possible associations between administration of pharmacological agents with LBD pathology and disease duration was also examined. Results: The hippocampus, thalamus and cingulate cortex - crucial components of the Papez circuit - were most affected by the proteinopathies, particularly deposition that correlated with the onset of some DLB symptomatology and non-motor symptoms. LC noradrenergic neurons were reduced in LBD compared to PD. The 5-HT2A receptor seemed to be more abundant than the α2A-adrenergic receptor (AR) and serotonin transporter (SERT) in the frontal cortex of a PD patient than a PDD or DLB patient. Conclusion: LBD phenotypes may be differentiated through their limbic involvement in the Papez circuit, where α-syn accumulation may contribute to non-motor symptoms. The behaviour of each protein type may be extremely heterogenous within each region of the noradrenergic and serotonergic systems, such that it correlates with the onset of different symptoms. There may be lower expression of receptors in LBD than PD patients, perhaps due to end-stage disease and more widespread degeneration. Hence, this study may have provided further insights into LBD pathophysiology and possibly assist clinical trials in future therapeutic interventions.

description: Functionalized high-aspect-ratio silver nanowires (AgNWs) have been recognized as one of the most promising alternatives for fabricating products, with their use ranging from electronic devices to biomedical fields. Given concerns on the safety of AgNWs, there is an urgent need to investigate the relation between intrinsic properties of AgNWs and their toxicity. In this study, lettuce was exposed for either 6 or 18 d to different AgNWs to determine how the size/aspect ratio and coating of AgNWs affect the contributions of the dissolved and particulate Ag to the overall phytotoxicity and uptake kinetics. We found that the uncoated AgNW (39 nm diameter × 8.4 µm length) dissolved fastest of all AgNWs investigated. The phytotoxicity, uptake rate constants, and bioaccumulation factors of the PVP-coated AgNW (43 nm diameter × 1.8 µm length) and the uncoated AgNW (39 nm diameter × 8.4 µm length) were similar, and both were higher than that of the PVP-coated AgNW with the larger diameter(65 nm diameter × 4.4 µm length). These results showed that the diameter of the AgNWs predominantly affected toxicity and Ag accumulation in plants. Particulate Ag was found to be the predominant driver/descriptor of overall toxicity and Ag accumulation in the plants rather than dissolved Ag for all AgNWs tested. The relative contribution of dissolved versus particulate Ag to the overall effects was influenced by the exposure concentration and the extent of dissolution of AgNWs. This work highlights inherent particulate-dependent effects of AgNWs in plants and suggests that toxicokinetics should explicitly be considered for more nanomaterials and organisms, consequently providing more realistic input information for their environmental risk assessment.

description: The recent availability of radioactive beams has opened up a new era in nuclear physics. The interactions and structure of exotic nuclei close to the drip lines have been studied extensively world wide, and it has been revealed that unstable nuclei, having weakly bound nucleons, exhibit characteristic features such as a halo structure and a soft dipole excitation. We here review the developments of the physics of unstable nuclei in the past few decades. The topics discussed in this Chapter include the halo and skin structures, the Coulomb breakup, the dineutron correlation, the pair transfer reactions, the two-nucleon radioactivity, the appearance of new magic numbers, and the pygmy dipole resonances.

description: Given the rising prevalence of Diabetes and thus Diabetic Retinopathy in the world, developing better techniques for early detection is paramount. This study aims to build upon previous studies that used geometric quantitative features in OCTA images to classify Non-Proliferative Diabetic Retinopathy (NPDR). Six geometric features, three angle-related (VBA, CBA1 and CBA2) and three width-related (VBC, VWR1 and VWR2), were automatically calculated in four distinct types of analyses made possible by the classification of OCTA vessel structures in arteries and veins using a clustering technique built around four features derived from the same vessels in the relative OCT images. Arteries’ and veins’ features were calculated separately, their ratios were computed and then their separate measurements were put together in a “Weighted Average” method. Comparative analysis of healthy patients, patients with diabetes but no retinopathy (NoDR) and patients with various stages of NPDR was conducted. This study found that sensitivity increased in width-related measurements and decreased in angle-related ones compared with the previous study. Some explanations are proposed as causes of this difference. Also, it was observed that the ratio measurements between artery values and vein values do not seem to contribute to the classification of patients and data seem to suggest that arteries and veins may be affected in circa the same way by NPDR with respect to the analyzed six features. VBC and VWR1 showed very good ability to separate between Control and NoDR patients from the NPDR patients even with the most conservative Bonferroni Correction.

description: 1. Methyltransferase-like 21C (METTL21C) and insulin-like growth factor 2 mRNA-binding protein 1 (IGF2BP1) play important roles in the proliferation of chicken myoblasts. However, it remains unclear whether there is protein-protein interaction between METTL21C and IGF2BP1 to regulate proliferation of chicken myoblasts. 2. In this study, the Igf2bp1 gene was amplified from cDNA of liver tissue of Lueyang black-bone chicken to construct the overexpression vector HA-Igf2bp1. The HA-Igf2bp1 and Flag-Mettl21c vectors were individually transfected and co-transfected into HEK293T, respectively. Co-immunoprecipitation (Co-IP) assay indicated a protein-protein interaction between METTL21C and IGF2BP1. 3. Using the Western blotting and LC-MS/MS, it was found that METTL21C could mediate the lysine methylation modification of IGF2BP1. Furthermore, the His-tagged overexpression vector HA-Igf2bp1-His was constructed, transfected and co-transfected with Flag-Mettl21c into HEK293T. His-tagged IGF2BP1 was purified by nickel ion affinity chromatography. Western blotting revealed that IGF2BP1 was successfully purified, and the trimethylation modification level of co-transfection group was significantly elevated compared with the single-transfection Igf2bp1 group. 4. Mettl21c and Igf2bp1 overexpression vectors were transfected and co-transfected into primary chicken myoblasts, respectively. The results of 5-ethynyl-2’-deoxyuridine assay and the expression level of Pax7 and MyoD indicated that overexpression of Igf2bp1 alone inhibited the chicken myoblast proliferation, whereas co-expression of Mettl21c and Igf2bp1 eliminated the inhibitory effects of Igf2bp1, thereby favouring cell proliferation and differentiation. 5. The results, for the first time, revealed that METTL21C mediated the lysine trimethylation modification of IGF2BP1 to regulate the proliferation of chicken myoblasts, which provided a new insight into in-depth analysis of the molecular mechanism of METTL21C methylation involved in regulating the growth and development of skeletal muscle in Lueyang black-bone chicken.
Amplitude ansatz analysis of the decay B0->K*0μ+μ-
Creators: name: Birch, Matthew
Publisher: name: Imperial College London
Year: 2023

description: The LHCb experiment at CERN has produced many intriguing results in b->sll and b->clν decays, which point to potential contributions from New Physics. This thesis describes an analysis of B0->K*0μ+μ- where the decay amplitudes are measured as functions of q2, the dimuon invariant mass squared. Measuring the angular distribution of this decay results in a plethora of observables that can be used to constrain the type of New Physics contributions. Owing to the number of parameterisations of the Standard Model and other models which can describe New Physics effects, Legendre polynomial ansatzes are used to describe the variation with q 2 in order to be as model-independent as possible. A selection strategy for B0->K*0μ+μ- is outlined, resulting in low levels of misidentified and combinatorial background. Pseudoexperiment studies are performed in order to develop the analysis strategy and further understand the symmetries of the angular distribution and the fit. Blinded results from 9 fb−1 of data collected by the LHCb detector at the LHC at CERN are shown, where the fit is performed in the region 1.25 < q2 < 8 GeV2/c4 . The fit is performed with four-parameter ansatzes for the P-wave and one-parameter ansatzes for the S-wave. Pseudoexperiment studies are performed from the data fit. The data fit quality is determined to be good, with p-value = 70%. Where the Hessian is not a good description of the uncertainties, fits to the log-likelihood profiles are performed with bifurcated parabolas to extract the uncertainties, resulting in good-quality statistical coverage.
A Combinatorial Version of the Svenonius Theorem on Definability

description: The Svenonius theorem describes the (first-order) definability in a structure in terms of permutations preserving the relations of elementary extensions of the structure. In the present paper we prove a version of this theorem using permutations of sequences over the original structure (these are permutations of sequences of tuples of the structure elements as well). We say that such a permutation $φ$ almost preserves a relation if for every sequence of its arguments the value of the relation on an $n$-th element of the sequence and on its image under $φ$ coincide for almost all numbers $n.$ We prove that a relation is definable in a structure iff the relation is almost preserved by all permutations almost preserving the relations of the structure. This version limits consideration to the original structure only and does not refer to any logical notion, such as "elementary equivalence".

description: Working with a custom-coded, automated-art-system of their own devising, Australian digital artists Karen Ann Donnachie and Andy Simionato have now archived a literary corpus for future study in what they have called The Library of Nonhuman Books. Yet it remains uncertain whether human scholars will visit Donnachie's and Simoniato's virtual library. Seeing as how "there are no human ‘typewriters’ now, how can we be sure there will still be human ‘readers’ in the future?"

description: A indústria de laticínios processa o leite de diversas formas, consequentemente gera uma gama de efluentes característicos dos processos inerentes a ela. Estes efluentes acabam por exigir um tratamento diferenciado, devido à sua elevada carga orgânica que é função direta de seu grande poder poluente. Deve-se então considerar o impacto do efluente no sistema de tratamento como fator preponderante em todo projeto, operação ou dimensionamento das unidades. A utilização da tecnologia anaeróbio para o tratamento do soro in natura encontra problemas como falta de alcalinidade, alta concentração de material orgânico oxidável (alto valor de DQO), tendência a acidificar rapidamente, possibilidade de formação de material polimérico de origem biológica que reduz a sedimentabilidade do lodo, podendo ocasionar perda da biomassa, ainda a possível deficiência de micronutrientes. Desta forma este projeto propõe uma investigação do processo de tratamento anaeróbio do soro de leite, em reator agitado com biomassa granulada e operando em batelada sequencial; estudando a influência do aumento da carga orgânica volumétrica processada e a necessidade de correção da alcalinidade por meio da adição de bicarbonato de sódio sobre a estabilidade e eficiência do processo.
