description: With particular reference to the role of the renormalization group approach and Ward identities, we start by recalling some old features of the one-dimensional Luttinger liquid as the prototype of non-Fermi-liquid behavior. Its dimensional crossover to the Landau normal Fermi liquid implies that a non-Fermi liquid, as, e.g., the normal phase of the cuprate high temperature superconductors, can be maintained in d>1, only in the presence of a sufficiently singular effective interaction among the charge carriers. This is the case when, nearby an instability, the interaction is mediated by fluctuations. We are then led to introduce the specific case of superconductivity in cuprates as an example of avoided quantum criticality. We will disentangle the fluctuations which act as mediators of singular electron-electron interaction, enlightening the possible order competing with superconductivity and a mechanism for the non-Fermi-liquid behavior of the metallic phase. This paper is not meant to be a comprehensive review. Many important contributions will not be considered. We will also avoid using extensive technicalities and making full calculations for which we refer to the original papers and to the many good available reviews. We will here only follow one line of reasoning which guided our research activity in this field.

Entre risas y escalofríos: los imaginarios apocalípticos en la ciudad Latinoamericana (siglos XX y XXI)
Creators: name: Gaytán Cuesta, Andrea Adhara
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation analyzes chronicles, novels, comics, poetry, theatre, films, and visual art that present the end of the world as a subversive and resistant response to the capitalist and neoliberal power structure of the Latin American city from last half of the 20th century to the beginnings of the 21st century. I have identified three areas of urban apocalypse in Latin America, which structure my chapters: 1) Eco-apocalypse, where I draw from indigenous thought to develop a new epistemology that is centered on seismic imaginaries in Mexican cultural production (cultural productions about earthquakes); 2) Socio-apocalypse, which portrays the end of the world as a result of the decomposition of society which is a direct consequence of violence, infection and the cannibal city (cultural productions about zombies); and 3)Techno-apocalypse or the end of the world due to technological monstrosities, which depicts the destruction of vital urban spaces as a result of technological disasters as evidenced in Glitch Cinema. In addition to foregrounding the emergence of an apocalyptic Latin American paradigm, opposed to the hegemonic structure adopted from the U.S., I claim that these imaginaries unmask new approaches to trauma, memory and urban theories, from a Latin American perspective. Using the frameworks of ecocriticism, anthropology of disaster, urban studies, postmodernism and even engineering in risk management and computer science, I examine audiovisual media, literature, performance, comics, and visual art to trace and uncover these artists, and find a reason why their creations were developed. By engaging interdisciplinary dialogue and a unique connection between science and humanities, these works contribute to global discussions about apocalyptic imaginaries, representing the challenges of the region. Through horror, humor and satire, I conclude that these productions are a cathartic tool that helps the elaboration of trauma, memory, uncertainties and inequalities of the region.

description: Tutorial videos are a valuable resource for people looking to learn new tasks. People often learn these skills by viewing multiple tutorial videos to get an overall understanding of a task by looking at different approaches to achieve the task. However, navigating through multiple videos can be time-consuming and mentally demanding as these videos are scattered and not easy to skim. We propose VideoMix, a system that helps users gain a holistic understanding of a how-to task by aggregating information from multiple videos on the task. Insights from our formative study (N=12) reveal that learners value understanding potential outcomes, required materials, alternative methods, and important details shared by different videos. Powered by a Vision-Language Model pipeline, VideoMix extracts and organizes this information, presenting concise textual summaries alongside relevant video clips, enabling users to quickly digest and navigate the content. A comparative user study (N=12) demonstrated that VideoMix enabled participants to gain a more comprehensive understanding of tasks with greater efficiency than a baseline video interface, where videos are viewed independently. Our findings highlight the potential of a task-oriented, multi-video approach where videos are organized around a shared goal, offering an enhanced alternative to conventional video-based learning.

description: This dissertation uses institutional ethnography to explore the work processes of paramedics and other EMS personnel in Calgary, Alberta. I focus specifically on the work of paramedics and explicating how front-line emergency medical services work is organized and coordinated by different technologies of coordination and control. This research relied on over 200 hours of observations of paramedics, over 100 interviews with paramedics about their work processes, and numerous hours of observations and interviews with emergency medical personnel. The findings report on the complex work of paramedics as they orient to their ever-changing work-settings, patients, and technological devices they work with. Furthermore, I explore how information in emergency medical services is put together by different text-mediated knowledge processes. In doing so, this dissertation explores the complex work of paramedics in the 21st century and explicates how their work is organized and reorganized by reform and restructuring practices.

description: A dipolar condensate confined in a toroidal trap constitutes a self-induced Josepshon junction when the dipoles are oriented perpendicularly to the trap symmetry axis and the s-wave scattering length is small enough. The ring-shaped double-well potential coming from the anisotropic character of the mean-field dipolar interaction is robust enough to sustain self-trapping dynamics, which takes place when the initial population imbalance between the two wells is large. We show that in this system the self-trapping regime is directly related to a vortex-induced phase-slip dynamics. A vortex and antivortex are spontaneously nucleated in the low density regions, before a minimum of the population imbalance is reached, and then cross the toroidal section in opposite directions through the junctions.This vortex dynamics yields a phase slip between the two weakly linked condensates causing an inversion of the particle flux.

description: A historical view that Charles Darwin was on par on the cause of freeing the slaves as President Lincoln is in vogue as of late. This version of history unjustly robs Lincoln in order to canonize Darwin. The historical facts simply do not support the allegation that Charles Darwin had any positive effects on the cause of abolition. To the contrary, Charles Darwin represents a distinct step backwards from the formidable record of activism that his grandparents Erasmus Darwin and Josiah Wedgwood represent.

A Theoretical Framework for Distribution-Aware Dataset Search

description: Effective data discovery is a cornerstone of modern data-driven decision-making. Yet, identifying datasets with specific distributional characteristics, such as percentiles or preferences, remains challenging. While recent proposals have enabled users to search based on percentile predicates, much of the research in data discovery relies on heuristics. This paper presents the first theoretically backed framework that unifies data discovery under centralized and decentralized settings.
 Let $\mathcal{P}=\{P_1,...,P_N\}$ be a repository of $N$ datasets, where $P_i\subset \mathbb{R}^d$, for $d=O(1)$ . We study the percentile indexing (Ptile) problem and the preference indexing (Pref) problem under the centralized and the federated setting. In the centralized setting we assume direct access to the datasets. In the federated setting we assume access to a synopsis of each dataset. The goal of Ptile is to construct a data structure such that given a predicate (rectangle $R$ and interval $θ$) report all indexes $J$ such that $j\in J$ iff $|P_j\cap R|/|P_j|\inθ$. The goal of Pref is to construct a data structure such that given a predicate (vector $v$ and interval $θ$) report all indexes $J$ such that $j\in J$ iff $ω(P_j,v)\in θ$, where $ω(P_j,v)$ is the inner-product of the $k$-th largest projection of $P_j$ on $v$. We first show that we cannot hope for near-linear data structures with polylogarithmic query time in the centralized setting. Next we show $\tilde{O}(N)$ space data structures that answer Ptile and Pref queries in $\tilde{O}(1+OUT)$ time, where $OUT$ is the output size. Each data structure returns a set of indexes $J$ such that i) for every $P_i$ that satisfies the predicate, $i\in J$ and ii) if $j\in J$ then $P_j$ satisfies the predicate up to an additive error $\varepsilon+2δ$, where $\varepsilon\in(0,1)$ and $δ$ is the error of synopses.

description: This paper deals with the modeling of social competition, possibly resulting in the onset of extreme conflicts. More precisely, we discuss models describing the interplay between individual competition for wealth distribution that, when coupled with political stances coming from support or opposition to a government, may give rise to strongly self-enhanced effects. The latter may be thought of as the early stages of massive, unpredictable events known as Black Swans, although no analysis of any fully-developed Black Swan is provided here. Our approach makes use of the framework of the kinetic theory for active particles, where nonlinear interactions among subjects are modeled according to game-theoretical tools.

description: The purpose of the study was to explore the phenomenon of K-12 educators using Twitter to support their informal professional learning. The research used a case study design with both qualitative and quantitative data sources. Data were collected using three procedures: an adapted version of the Constructivist On-Line Learning Environment Survey (COLLES) (Taylor & Maor, 2000a, 2000b), semi-structured interviews and online Twitter content. The findings demonstrated that Twitter was used to complement professional learning by accessing and sharing information, as a catalyst for learning beyond Twitter and for collaborative dialogue and discourse. Further, the findings indicated the reason educators used Twitter was to experience professional learning that was personalized and relevant, through access to information and resources while also establishing and developing connections to others. Such learning opportunities occurred through various interactions that built and supported learning networks while allowing educators to participate to varying degrees.

description: Abstract In this case study, I examined how teachers working in a demonstration school, influenced by the principles of the Reggio Emilia Approach, negotiate the federal mandates from the No Child Left Behind (NCLB) Act. Drawing from Bronfenbrenner’s (2005) ecological system theory as a framework for analysis, I examine in this thesis how the arm’s-length educational reforms from NCLB become a mitigating factor on how the image of the child as a principle is taken up by teachers. The findings of this case study identify changes in teachers’ thinking and practice in classrooms and across the school, and how this impacts relationships, the development of curriculum, projects, the use of documentation, and roles within the school over time.
Microscopic characterization of a putative ER-membrane targeted Puf RNA-binding protein in Arabidopsis thaliana

description: Cellular messenger RNAs (mRNAs) are associated with RNA-binding proteins (RBPs) that form ribonucleoprotein (RNP) complexes. These RNP complexes are the functional units that participate in post-transcriptional gene regulation activities. One group of RBPs that plays an important role in regulating cytoplasmic post-transcriptional control is the Puf family of RNA-binding proteins. Some of the general characteristics of plant Puf proteins, including their biochemistry, systematics and cell biology, have been studied in the Muench laboratory. The research reported in this thesis was aimed at conducting a microscopic characterization of a Puf protein, APUM6 that potentially targets to the membrane of the endoplasmic reticulum (ER). The ER is an organelle that has an essential role in protein synthesis. APUM6 does not appear to possess a signal peptide that is common in ER targeted proteins. Hydrophobicity plots further indicate the presence of a weak hydrophobic region that could assist in ER-anchorage. The hypothesis of this thesis is that APUM6 anchors to the membrane of the ER and that this membrane anchorage is facilitated by a palmitoylation, a post-translational modification that attaches a palmitate to a cysteine residue in the protein to increase membrane-protein interactions. Also, it is proposed that the cytoskeleton plays an important role in the localization of APUM6. First, the subcellular localization of APUM6 was determined by expressing it as a fluorescent fusion protein in epidermal cells of fava bean and Arabidopsis using confocal laser scanning microscopy. These experiments determined that APUM6 is indeed localized to the ER membrane. Second, using cytoskeletal disrupting drugs, it was demonstrated that cytoskeleton was not involved in the localization of APUM6. Also, palmitoylation inhibitor 2-bromopalmitate treatment showed that palmitoylation likely is not mediating the anchoring of APUM6 on the ER membrane. The possible role for an ER targeted Puf protein could be to facilitate targeting of mRNAs that encode secretory or cytosolic proteins to the ER surface in order to enhance the efficiency of translation/and or import into the ER.

description: The hippocampus is thought to mediate episodic memory through the instantiation and reinstatement of context-specific cognitive maps. However, recent longitudinal experiments have challenged this view, reporting that most hippocampal cells change their tuning properties over days even in the same environment. Often referred to as neural or representational drift, these dynamics raise questions about the capacity and content of the hippocampal code. One such question is whether and how these long-term dynamics impact the hippocampal code for context. To address this, we image large CA1 populations over more than a month of daily experience as freely behaving mice participate in an extended geometric morph paradigm. We find that long-timescale changes in population activity occur orthogonally to the representation of context in network space, allowing for consistent readout of contextual information across weeks. This population-level structure is supported by heterogeneous patterns of activity at the level of individual cells, where we observe evidence of a positive relationship between interpretable contextual coding and long-term stability. Together, these results demonstrate that long-timescale changes to the CA1 spatial code preserve the relative structure of contextual representation.

description: The following project analyzes the crucial navigational and astrological discourses that appear throughout the Solitudes. Historical and scientific information pertinent to the subject was utilized to set forth a literary analysis of the poem. In the first chapter, the history of Spanish navigation is summarized from the 15th to the 17th centuries, during which time Spain enjoyed global dominance. The second chapter discusses the astrological and astronomical sciences that were of extreme importance during Spain’s expansion. The literary analysis takes place in the last two chapters, and includes the application of the information discussed in the previous chapters to examine the navigational and astrological discourses in the text. In conclusion, it is established that the author chose navigation and astrology, two crucial practices of society, to both criticize the Spanish government of the era, and enhance the powerful imagery of his poem.

description: Photon counting measurements are analyzed for obtaining a classical phase parameter in linear Mach Zehnder interferometer (MZI), by the use of phase estimation theories. The detailed analysis is made for four cases: a) Coherent states inserted into the interferometer. b) Fock number state inserted in one input port of the interferometer and the vacuum into the other input port. c) Coherent state inserted into one input port of the interferometer and squeezed-vacuum state in the other input port. d) Exchanging the first beam-splitter (BS1) of a MZI by a non-linear system which inserts a NOON state into the interferometer and by using photon counting for parity measurements. The properties of photon counting for obtaining minimal phase uncertainties for the above special cases and for the general case are discussed.

Functional Uniform Priors for Nonlinear Modelling

description: This paper considers the topic of finding prior distributions when a major component of the statistical model depends on a nonlinear function. Using results on how to construct uniform distributions in general metric spaces, we propose a prior distribution that is uniform in the space of functional shapes of the underlying nonlinear function and then back-transform to obtain a prior distribution for the original model parameters. The primary application considered in this article is nonlinear regression, but the idea might be of interest beyond this case. For nonlinear regression the so constructed priors have the advantage that they are parametrization invariant and do not violate the likelihood principle, as opposed to uniform distributions on the parameters or the Jeffrey's prior, respectively. The utility of the proposed priors is demonstrated in the context of nonlinear regression modelling in clinical dose-finding trials, through a real data example and simulation. In addition the proposed priors are used for calculation of an optimal Bayesian design.

Porous Yttria-Stabilized Zirconia Microstructures for SOFC Anode Fabrication

description: Solid oxide fuel cells (SOFCs) are electrochemical devices that convert fuels, such as hydrogen and natural gas, to electricity at high efficiencies, e.g., up to 90 %. SOFCs are emerging as a key technology for energy production that also minimize greenhouse gas emissions compared to conventional thermal power generation. SOFCs, which are normally based on nickel-yttria stabilized zirconia (YSZ) anodes, undergo degradation with time due to their high operating temperatures and their susceptibility to damage due to anode oxidation (redox cycling) and poisoning. Ni infiltration into porous YSZ scaffolds is considered to be a promising approach for overcoming some of these problems and enhancing their redox tolerance. However, long-term instability of the morphology of these types of anodes is an important problem. The focus of this thesis was therefore to develop methods to form porous YSZ scaffolds and attempt to construct stable Ni-YSZ anodes with reasonable electrochemical performance by infiltration. In this work, the issue of long-term instability was considered to originate from both the porous YSZ scaffold microstructure and the Ni infiltration precursor employed. To study this more closely, two different porous YSZ scaffold microstructures were developed by using tape casting, followed by Ni infiltration using a polymeric precursor, known to form a continuous Ni phase, rather than electrically separated Ni particles. Ni infiltration into porous YSZ scaffolds with large grains (0.5 µm) and large pores (two types of pores: ~0.5 µm and 5 µm) resulted in extensive Ni particle growth that resulted in poor stability and poor electrochemical performance (0.5 Ω cm2 per electrode at 800 °C). Ni infiltration into a scaffold having finer grains and pores (~200 nm each) resulted in anodes with a much lower polarization resistance of 0.11 Ω cm2 per electrode at 800 °C, increasing by ~ 5 % after 108 hours at this temperature.

A 33X50 cm2 GRPC detector equipped with a power-pulsed electronics board offering a 1cm2 lateral segmentation was successfully tested in a 3-Tesla magnet operating at the H2 beam line of the CERN SPS. An important reduction of power consumption with no deterioration of the detector performance is obtained when the power-pulsing mode is applied. This important result shows that ultra-granular calorimeters for ILC experiments are not only an attractive but also a realistic option.

description: Silchester (Calleva) experienced major disruption in the late first century A.D. as the Iron Age oppidum was transformed into the Roman city responsible for the administration of the civitas of the Atrebates. Aligned on the cardinal points, a rectilinear street grid was laid across the settlement replacing the late Iron Age network of streets and lanes oriented north-west/south-east and north-east/south-west. While the pre-existing property boundaries within Insula IX were retained there was a total re-build within them. The excavated area contained one complete property and fragments of three of its neighbours. Rather than conform to the new grid all the buildings were constructed at 45 degrees to it, reasserting the late Iron Age orientations. The timber-framed buildings within the complete property consisted of a row of three a rectangular kitchen, a town-house and a roundhouse separated by a yard from a re-built taberna, also diagonal to the street on which it fronted. The surgical and writing instruments associated with the circular building suggested it functioned as a healers and/or teachers house. This volume completes the publication of the excavations in Insula IX, 1997-2014.

description: This dissertation focuses on Jewish and Islamic websites that allow their visitors to pose questions relating to religious law to well-known rabbis and muftīs, receive an answer on the website itself; and, in some cases, comment on the scholars’ answers. The Q&A reviewed focused on the attitudes towards various ‘others’: members of other faiths, members of a nation in conflict with their own, and those challenging traditional religious gender roles. Utilizing a discourse analysis, case study approach, several research questions are posed: are online Questions and Answers compatible with traditional religious Q&A or are the websites creating a new form of religious discourse? Are online Q&A marking the boundaries of a religious Enclave, and who is setting these boundaries? How are the various ‘others’ treated? Is the medium actually creating a democratic, rational-critical discourse, resembling Habermas’ ideal public sphere? And does the medium’s public nature enable the religious scholars to assume the role of public intellectuals? The theoretical framework for the dissertation is outlined in Chapter II, which reviews the concepts of the “other” and the “Enclave”. The chapter then turns to theories of public discourse, primarily Jürgen Habermas’ “Public Sphere,” as well as the rise (and perhaps fall) of public intellectuals and an evaluation of the internet as a vehicle for democratic public discourse. Chapter III examines the development of Jewish and Islamic law, with a special focus on the Q&A genre. Chapter IV evaluates Q&A websites as an ideal public sphere, as well as in comparison to traditional Q&A. The second part of the chapter presents a case study dealing with social interaction with non-Jews and non-Muslims, which aids in defining the characteristics of online Q&A. Chapter V focuses on a political ‘other’; it reviews Q&A from Jewish Religious-Zionist and Islamic “Centrist” websites, focusing on issues related to the Israeli-Palestinian conflict. Chapter VI focuses on the ‘other’ from within – Jewish and Muslim women who challenge their conventional religious roles. The dissertation ends with Chapter VII, presenting the study’s conclusions, as well as a look into current trends in online religious discourse, beyond the realm of Q&A websites.

description: The self-retracting motion of a graphene flake on a stack of graphene flakes is studied using molecular dynamics simulations. It is shown that in the case when the extended flake is initially rotated to an incommensurate state, there is no barrier to the self-retracting motion of the flake and the flake retracts as fast as possible. If the extended flake is initially commensurate with the other flakes, the self-retracting motion is hindered by potential energy barriers. However, in this case, the rotation of the flake to incommensurate states is often observed. Such a rotation is found to be induced by the torque acting on the flake on hills of the potential relief of the interaction energy between the flakes. Contrary to carbon nanotubes, telescopic oscillations of the graphene flake are suppressed because of the high dynamic friction related to the excitation of flexural vibrations of the flake. This makes graphene promising for the use in fast-responding electromechanical memory cells.

description: L'association Expédition MED est un collectif de scientifiques, d'environnementalistes et de citoyens européens qui, depuis 2009, mène différentes actions pour lutter contre la pollution par les matières plastiques avec des campagnes de sensibilisation par des expositions itinérantes, du lobbying auprès des instances décisionnelles, des campagnes scientifiques en mer et dans les cours d'eau pour renforcer les connaissances sur la pollution plastique.
Face à la nécessité de limiter des impacts de la pollution plastique sur les mers et océans, Expédition MED a initié en 2021 une expédition inédite : Vigieplastic Méditerranée. Ce programme vise à promouvoir une approche régionale commune sur la connaissance de la pollution plastique en Méditerranée. Durant l'été 2021, le navire de l'association, laboratoire citoyen, a embarqué une soixantaine de scientifiques, marins et écolovolontaires pour une campagne de 7 semaines en Mer Méditerranée. L'expédition s'est déroulée dans le bassin Nord Occidental Méditerranéen du 22 juillet au 3 septembre, au départ de Fiumicino (Rome) et à destination de Marseille.
L'un des principaux objectifs de la mission était de quantifier et caractériser la pollution par les microplastiques de surface. Au total , 47 prélèvement d'eau de surface ont été réalisés. Le présent rapport vient compléter le rapport préliminaire de campagne, en intégrant les analyses de la fraction inférieure à 1 mm, traitée à posteriori à terre. Pour chaque prélèvement, les microplastiques sont comptabilisés et classés en termes de classe de taille, forme et couleur. Les résultats sont regroupés par subdivision de la Mer Méditerranée : Mer de Ligurie, Mer Tyrrhénienne, Mer des Baléares, Golfe du Lion et Mer de Sardaigne.

description: We present properties of individual and composite rest-UV spectra of continuum- and narrowband-selected star-forming galaxies (SFGs) at a redshift of 220 Å, the canonical limit to be classified as a LAE. We divide our dataset into subsamples based on properties we are able to measure for each individual galaxy: Lyα equivalent width, rest-frame UV colors, and redshift. Among our subsample of galaxies with R<25.5, those with rest-frame W_{Lyα}>20 Å have bluer UV continua, weaker low-ionization interstellar absorption lines, weaker C IV absorption, and stronger Si II* nebular emission than those with W_{Lyα}<20 Å. We measure a typical velocity offset of Δv~600 km s$^{-1}$ between Lyα emission and low-ionization absorption among our subsamples. We find that the interstellar component, as opposed to the stellar component, dominates the high-ionization absorption line profiles. We find the low- and high-ionization Si ionization states have similar kinematic properties, yet the low-ionization absorption is correlated with Ly$α$ emission and the high-ionization absorption is not. These trends are consistent with outflowing neutral gas being in the form of neutral clouds embedded in ionized gas as previously suggested by \cite{Steidel2010}. Moreover, our galaxies with bluer UV colors have stronger Lyα emission, weaker low-ionization absorption and more prominent nebular emission line profiles. Among our dataset, UV-bright galaxies with W_{Lyα}>20 Å exhibit weaker Lyα emission at lower redshifts, although we caution that this could be caused by spectroscopic confirmation of low Lyα equivalent width galaxies being harder at z~3 than z~2.

Functional characterization of human variants of NFKBIA : a key regulator of immune responsiveness implicated in susceptibility to infectious and inflammatory disease
Creators: name: Ali, Salman

description: IkBα is an important regulator of inflammation. Single nucleotide polymorphisms (SNPs) rs3138053, rs2233406 and rs2233409 in the promoter of the gene NFKBIA, which encodes for IkBα, have been shown to be associated with a variety of infectious and inflammatory conditions. In this study, we investigated the functional impact of the promoter variants of NFKBIA on human immune responsiveness. Using a coding SNP that was in strong linkage disequilibrium (LD) with NFKBIA SNPs rs3138053/rs2233406/rs2233409, we designed and validated an allele-specific PCR assay that could detect subtle differences in allele ratios between the major (ACC) and minor (GTT) promoter variants of SNPs rs3138053/rs2233406/rs2233409. Peripheral blood mononuclear cells (PBMCs) of homozygous (ACC/ACC) and heterozygous (ACC/GTT) individuals were stimulated with 100ng/ml LPS and live cultures of Streptococcus pneumoniae (moi 7.8-30) serotype 14 for 3 and 4 hours. PBMCs of neonatal NFKBIA homozygotes and heterozygotes were stimulated with various Toll-like-receptor (TLR) ligands of the innate immunity cascade to assay for differences in the innate immune response. NFKBIA heterozygotes of European descent displayed 1.21 (1.14-1.27 95% CI)-1.26 (1.18-1.34 95% CI) fold higher expression of the major allele transcript (ACC) relative to the minor allele transcript (GTT). For the same ethnicity, at 3 hours stimulation, NFKBIA homozygotes (ACC/ACC) produced higher levels of NFKBIA mRNA than heterozygotes following stimulation with LPS (1.4 fold. p=0.0095) and S. pneumoniae (1.51 fold, p=0.024). Higher TNFα secretion was seen from PBMCs of heterozygotes as compared to homozygotes (of European descent) in the presence of LPS (1.57 fold , p<0.05 at a dose of 100ng/ml), Pam3CSK4 (2.29 fold, p<0.01 at a dose of 100ng/ml and 1.91 fold, p<0.05 at a dose of 1000 ng/ml), 3M003 (1.79 fold, p<0.001 at a dose 10μM) and 3M002 (3.30 fold, p<0.001 at a dose of 10μM). The results presented here provide preliminary functional evidence behind the observed associations of these SNPs with infectious and inflammatory conditions. A global understanding of the functional consequences of regulatory polymorphisms of NFKBIA will be provided with subsequent experiments that examine differences between all NFKBIA genotypes (including minor allele homozygotes) for IκBα protein expression and NF-κB translocation in all major ethnic groups.

description: Exploiting the fact that light propagation in defocusing nonlinear media can mimic the transonic flow of an equivalent fluid, we demonstrate experimentally the formation of an all-optical event horizon in a waveguide structure akin to a hydrodynamic Laval nozzle. The analogue event horizon, which forms at the nozzle throat is suggested as a novel platform for analogous gravity experiments.

description: This M.Sc. thesis focuses on improving the convergence rates of kernel density estimators. Firstly, a bias reduced kernel density estimator is introduced and investigated. In order to reduce bias, we intuitively subtract an estimated bias term from ordinary kernel density estimator. Theoretical properties such as bias, variance and mean squared error are investigated for this estimator and comparisons with ordinary kernel density estimator and location-scale kernel density estimator are made. Compared with the ordinary density estimator, this estimator has reduced bias and mean squared error (MSE) of the order O(h^3) and O(n^(-6/7))，respectively, and even further reduced orders O(h^4) and O(n^(-8 9)) respectively when the kernel is chosen symmetric. Secondly, we propose a geometric extrapolation of the location-scale kernel estimator and a geometric extrapolation of the bias reduced kernel estimator introduced above. Similarly, we investigate their theoretical properties and compare them with the geometric extrapolation of ordinary kernel estimator. These results show that among the three geometric extrapolated kernel estimators, the one based on bias reduced kernel estimator has smallest bias and MSE. The geometric extrapolation of bias reduced kernel estimator can improve the convergence rates of bias and MSE to O(h^6) and O(n^(-12/13)) respectively for symmetric kernels. The geometric extrapolation of location-scale kernel estimator can reduce bias and MSE of location-scale kernel estimator, however it has bias and MSE with a slower rate than those of the geometric extrapolation of ordinary kernel estimator. In order to assess nite sample performances of the proposed estimators, Monte Carlo simulation studies based on small to moderately large samples are carried out. Finally, an analysis of the old faithful geyser data are presented to demonstrate the proposed methods. Both the simulation studies and the real data analysis consolidate our theoretical findings.
