Curvature Induced Phase Transition in a Four-Fermion Theory Using the Weak Curvature Expansion

description: Curvature induced phase transition is thoroughly investigated in a four- fermion theory with $N$ components of fermions for arbitrary space-time dimensions $(2 \leq D < 4)$. We adopt the $1/N$ expansion method and calculate the effective potential for a composite operator $\barψψ$. The resulting effective potential is expanded asymptotically in terms of the space-time curvature $R$ by using the Riemann normal coordinate. We assume that the space-time curves slowly and keep only terms independent of $R$ and terms linear in $R$. Evaluating the effective potential it is found that the first-order phase transition is caused and the broken chiral symmetry is restored for a large positive curvature. In the space-time with a negative curvature the chiral symmetry is broken down even if the coupling constant of the four-fermion interaction is sufficiently small. We present the behavior of the dynamically generated fermion mass. The critical curvature, $R_{cr}$, which divides the symmetric and asymmetric phases is obtained analytically as a function of the space-time dimension $D$. At the four-dimensional limit our result $R_{cr}$ agrees with the exact results known in de Sitter space and Einstein universe.

description: The synthesis of a [2]rotaxane, comprising a calix[6]arene-wheel and a dibenzyl-ammonium axle, is here reported. By virtue of its inherent directionality, the calix-wheel makes non-degenerate two equivalent stations of the symmetrical axle. In this way, the neutral rotaxane shows two co-conformations, named endo-alkyl and endo-benzyl, in which an alkyl or benzyl moiety of the axle are included inside the calix-cavity, respectively. NMR and DFT studies showed that the co-conformation preferred by the neutral mechanomolecule is the ‘endo-alkyl’ one, which is more stabilized by C-H···π interactions between the included alkyl chain and the aromatic wall of the calix-cavity.

description: Ga$_2$O$_3$ and (Al$_x$Ga$_{1-x}$)$_2$O$_3$ alloys are promising materials for solar-blind UV photodetectors and high-power transistors. Basic key parameters in the device design, such as band gap variation with alloy composition and band offset between Ga$_2$O$_3$ and (Al$_x$Ga$_{1-x}$)$_2$O$_3$, are yet to be established. Using density functional theory with the HSE hybrid functional, we compute formation enthalpies, band gaps, and band edge positions of (Al$_x$Ga$_{1-x}$)$_2$O$_3$ alloys in the monoclinic ($β$) and corundum ($α$) phases. We find the formation enthlapies of (Al$_x$Ga$_{1-x}$)$_2$O$_3$ alloys are significantly lower than of (In$_x$Ga$_{1-x}$)$_2$O$_3$, and that (Al$_x$Ga$_{1-x}$)$_2$O$_3$ with $x$=0.5 can be considered as an ordered compound AlGaO$_3$ in the monoclinic phase, with Al occupying the octahedral sites and Ga occupying the tetrahedral sites. The direct band gaps of the alloys range from 4.69 to 7.03 eV for $β$-(Al$_x$Ga$_{1-x}$)$_2$O$_3$ and from 5.26 to 8.56 eV for $α$-(Al$_x$Ga$_{1-x}$)$_2$O$_3$. Most of the band offset of the (Al$_x$Ga$_{1-x}$)$_2$O$_3$ alloy arises from the discontinuity in the conduction band. Our results are used to explain the available experimental data, and consequences for designing modulation-doped field effect transistors (MODFETs) based on (Al$_x$Ga$_{1-x}$)$_2$O$_3$/Ga$_2$O$_3$ are discussed.

description: We present the kinematic anaylsis of $246$ stars within $4^\prime$ from the center of Orion Nebula Cluster (ONC), the closest massive star cluster with active star formation across the full mass range, which provides valuable insights in the the formation and evolution of star cluster on an individual-star basis. High-precision radial velocities and surface temperatures are retrieved from spectra acquired by the NIRSPEC instrument used with adaptive optics (NIRSPAO) on the Keck II 10-m telescope. A three-dimensional kinematic map is then constructed by combining with the proper motions previously measured by the Hubble Space Telescope (HST) ACS/WFPC2/WFC3IR and Keck II NIRC2. The measured root-mean-squared velocity dispersion is $2.26\pm0.08~\mathrm{km}\,\mathrm{s}^{-1}$, significantly higher than the virial equilibrium's requirement of $1.73~\mathrm{km}\,\mathrm{s}^{-1}$, suggesting that the ONC core is supervirial, consistent with previous findings. Energy equipartition is not detected in the cluster. Most notably, the velocity of each star relative to its neighbors is found to be negatively correlated with stellar mass. Low-mass stars moving faster than their surrounding stars in a supervirial cluster suggests that the initial masses of forming stars may be related to their initial kinematic states. Additionally, a clockwise rotation preference is detected. A weak sign of inverse mass segregation is also identified among stars excluding the Trapezium stars, though it could be a sample bias. Finally, this study reports the discovery of four new candidate spectroscopic binary systems.

description: We present evidence of flux variability, on both short (hours) and long (months) time scales of the Seyfert 2 galaxy NGC 7172. These results are based on the ASCA observation of NGC 7172 performed on May 1996. The source was detected at a rather low flux level, about 3 times fainter than its usual state (including one year before, when it was also observed by ASCA). The source also varied by about 30 percent during the observation, confirming the presence of a type 1 nucleus in its center. However, its spectrum appears to be flatter than the typical Seyfert 1 spectrum (in agreement with findings on other Seyfert 2's), posing problems for the unification model unless complex absorption is invoked.

description: We demonstrate a robust method of resolving the star-formation and AGN contributions to emission lines using two very well known AGN systems: NGC 1365, and NGC 1068, using the high spatial resolution data from the TYPHOON/PrISM survey. We expand the previous method of calculating the AGN fraction by using theoretical-based model grids rather than empirical points. The high spatial resolution of the TYPHOON/PrISM observations show evidence of both star formation and AGN activity occurring in the nuclei of the two galaxies. We rebin the data to the lower resolutions, typically found in other integral field spectroscopy surveys such as SAMI, MaNGA, and CALIFA. The results show that when rebinned from the native resolution of TYPHOON (< 200 pc/pixel) to 1 kpc/pixel, the effects include a roughly 3 kpc increase in the radius of measured AGN activity, and a factor of 2 to 7 increase in the detection of low surface brightness features such as shocks. All of this information is critical, because information on certain physical processes may be lost at varying resolutions. We make recommendations for analysing data at current IFU survey resolutions.

Lossy Polynomial Datapath Synthesis
Creators: name: Drane, Theo
Publisher: name: Imperial College London
Year: 2013

description: The design of the compute elements of hardware, its datapath, plays a crucial role in determining the speed, area and power consumption of a device. The building blocks of datapath are polynomial in nature. Research into the implementation of adders and multipliers has a long history and developments in this area will continue. Despite such efficient building block implementations, correctly determining the necessary precision of each building block within a design is a challenge. It is typical that standard or uniform precisions are chosen, such as the IEEE floating point precisions. The hardware quality of the datapath is inextricably linked to the precisions of which it is composed. There is, however, another essential element that determines hardware quality, namely that of the accuracy of the components. If one were to implement each of the official IEEE rounding modes, significant differences in hardware quality would be found. But in the same fashion that standard precisions may be unnecessarily chosen, it is typical that components may be constructed to return one of these correctly rounded results, where in fact such accuracy is far from necessary. Unfortunately if a lesser accuracy is permissible then the techniques that exist to reduce hardware implementation cost by exploiting such freedom invariably produce an error with extremely difficult to determine properties. This thesis addresses the problem of how to construct hardware to efficiently implement fixed and floating-point polynomials while exploiting a global error freedom. This is a form of lossy synthesis. The fixed-point contributions include resource minimisation when implementing mutually exclusive polynomials, the construction of minimal lossy components with guaranteed worst case error and a technique for efficient composition of such components. Contributions are also made to how a floating-point polynomial can be implemented with guaranteed relative error.

The Role of Transparency in Consumer Brand Relationships
Creators: name: Liu, Yeyi
Publisher: name: Imperial College London
Year: 2013

description: The recent financial crisis has led to calls for effective communication between consumers and firms and for more attention to increasing transparency and reducing information asymmetries. This thesis aims to develope a construct such as transparency to effectively capture the free information flow between firms or their brands and consumers. Two questions are answered. First, how can consumer-brand communication be more effective, and thus lead to positive consumer affective and behavioral responses? Second, as WOM is an increasingly important channel for consumers to obtain information, what affects the generation of consumers positive eWOM on social online sites and how does eWOM on social online sites differ from traditional WOM? Two chapters articulate the defining elements of a brand transparency construct, empirically validate a scale to measure brand transparency, and show that brand transparency strengthens consumers’ trust in a brand, willingness to pay a price premium, and consumers’ attachment to a brand. The research also identifies important boundary conditions: The effects of transparency depend on consumers’ perceptions of brand ability and social responsibility associations, and the level of consumer involvement. Another chapter examines the roles of traditional WOM and eWOM on social sites in the relationships between brand attachment, attitude, and brand purchases. Specifically, the research explores antecedents of eWOM on social sites and studies the underlying process through which eWOM on social sites versus traditional WOM helps to predict purchase behavior. Moderators in these relationships is identified. Findings suggest that consumers are less likely to provide eWOM on social sites, but it explains the impact of brand attachment on brand purchase better than traditional WOM. The mediating effects are stronger for consumers with high desire for self-enhancement. The authors discuss the managerial and theoretical implications of their findings.

 English candidates undertaking a language exam. It further introduces the
 new Trinity Lancaster Corpus of L1 Spoken English (TLC-L1), a corpus
 developed to align in context to the TLC-L2 (Gablasova et al., 2019). By
 considering differing proficiency levels of L2 speakers, the research
 takes a pseudolongitudinal approach to investigate collocational
 development with core findings including the influence of topic and
 register on the use of collocations in a language exam, which are also
 reflected in the TLC-L1 corpus, as well as evidence of a nonlinear
 developmental trajectory of English language learners and their use of
 verb + noun collocations. Finally, the thesis brings three major
 contributions and implications to the field: (1) methodological with the
 development and application of a new corpus, (2) theoretical through the
 analysis of collocations in the under-investigated mode of speech and (3)
 pedagogical with suggestions and examples of corpus-informed language
 teaching materials.

description: Rare event search experiments using germanium detectors are operated in underground laboratories to minimize the background induced by cosmic rays. However, the cosmogenic activation in germanium crystals on the ground during fabrication and transportation generates long half-life radionuclides and contributes a considerable background. We simulated the production rates of cosmogenic radionuclides in germanium and calculated the specifi c activities of cosmogenic radionuclides according to the scheduled fabrication and transportation processes of $^{76}$Ge enriched germanium detectors. The impact of cosmogenic background in germanium crystals for the next generation CDEX experiment was assessed with the scheduled exposure history above ground.
title: The Cultural Lives of the Middling Sort in Early Modern Maritime London
Creators: name: Powell-Davies, Michael David
Publisher: name: University of Kent
Year: 2024

description: This thesis uncovers the cultural lives of maritime London's middling sort, c. 1580-1640. Tracing middling identities and experiences across the region's turbulent Thameside communities, I outline who were included among maritime London's middling sort of people, what it was that made them middling, and how these individuals were able to attain and maintain social status within the mobile and changing worlds they inhabited.

Each chapter introduces questions that probe the nature of middling status, and the subsequent answers bring into clearer focus the outline of this underexplored social group. To answer the questions raised by this thesis, I engage with a diverse range of print and manuscript sources, from political treatises, letter-writing manuals, nautical textbooks and maps to personal journals, administrative accounts, probate documents, and court materials. My first chapter explores the important role that officeholding and administrative culture played in the production and management of middling status. Election to local office not only affirmed the social status of the officeholder but also afforded the elected individual access to influential means of local administration, which I examine through the vestry minute book of maritime Stepney. My second chapter traces the life of Richard Norwood, a middling nautical practitioner who used public and paper performances to cultivate a range of distinct social and professional identities. By examining the texts and models of identity that Norwood produced and consumed throughout his lifetime, this chapter explores how middling status was constituted through performance, collaborative practices, and demonstrations of skill. My third chapter brings together the institutional and the individual by focusing on middling identity and experience in the East India Company's yard at Blackwall. Using quantitative and qualitative methods, I map the immense multipurpose site of Blackwall Yard and locate middling individuals and activities within its spaces. Having located the lives of the middling sort within the turbulent Thameside communities of early modern maritime London, I conclude by drawing my arguments together to demonstrate the importance of engaging with the specific, the material, the located, and the local.
Calibration and control of advanced ultrasonic array technology
Creators: name: Duxbury, David
Publisher: name: Imperial College London
Year: 2013

description: Ultrasonic inspection is the primary method of Non-Destructive Evaluation (NDE) for the detection of planar flaws in engineering components. In recent years phased array technology has been adopted for use in NDE following success in related fields, such as medical and sonar applications. Phased array technology provides increased flexibility relative to single element monolithic transducers and the development of controlling hardware with large numbers of parallel channels has allowed the use of large phased arrays able to focus at long range, and offer increased performance. Full Matrix Capture (FMC) is a method of recording data using a phased array transducer that allows image reconstruction to be performed for any inspection technique than could be deployed using delay laws applied to the transmit voltage pulses applied to the array and receiving amplifiers. FMC technology provides a step change in inspection flexibility, and also provides the opportunity to take advantage of imaging techniques that are not practical to implement using phased arrays in the conventional way. However, existing inspection calibration procedures defined in standards do not allow these benefits to be fully realised. This thesis reports the development of a calibration framework designed for FMC based inspection for both rigid and conformable wedge mounted arrays. A large part of this work has been the development of acceptance limits on transducer performance variations. The developments of these limits have required a significant amount of modelling work, often using a Monte Carlo approach. To accommodate this, modelling tools have been developed to investigate the effect of array element directivity, sensitivity, and relative phase on system performance. For conformable phased arrays the effect of surface profile measurement accuracies has also been assessed. The developed calibration framework includes the tools necessary to monitor transducer performance throughout an inspection, with minimum impact on inspection duration. A means of calibrating imaging tools against known reflectors, in accordance with established industrial practice, has also been produced.

description: Toxoplasmosis, while often an asymptomatic parasitic disease in healthy individuals, can cause severe complications in immunocompromised persons and during pregnancy. The most common method to diagnose Toxoplasma gondii infections is the serological determination of antibodies directed against parasite protein antigens. Here we report the use of a bead-based multiplex assay containing a synthetic phosphoglycan portion of the Toxoplasma gondii glycosylphosphatidylinositol (GPI1) for the detection of GPI1-specific antibodies in human sera. The glycan was conjugated to beads at the lipid site to retain its natural orientation and its immunogenic groups. We compared the response against GPI1 with that against the protein antigen SAG1, a common component of commercial serological assays, via the detection of parasite-specific human IgG and IgM antibodies, respectively. The GPI1-based test is in excellent agreement with the results for the commercial ELISA, as the ROC analysis of the GPI1 test shows 97% specificity and 98% sensitivity for the assay. GPI1 was a more reliable predictor for a parasite-specific IgM response compared to SAG1, indicating that a bead-based multiplex assay using GPI1 in combination with SAG1 may strengthen Toxoplasma gondii serology, in particular in seroepidemiological studies.

description: We study a brane-antibrane system and a non-BPS D-brane in SU(2) WZW model. We first discuss the tachyon condensation using the vertex operator formalism and find the generation of codimension two D-branes after the condensation. Our result is consistent with the recent interpretation that a D2-brane is a bound state of D0-branes. Then we investigate the world volume effective theory on a non-BPS D-brane. It becomes a field theory on the ``fuzzy sphere'' when the level is sent to infinity. The most interesting feature is that there exist the noncommutative tachyonic solitons and we can identify them with D0-branes. We also discuss the brane-antibrane system from the world volume point of view and comment on the relation to the noncommutative version of the index theorem.

description: We report J, H and K photometry of 86 stars in 40 fields in the northern hemisphere. The fields are smaller than or comparable to a 4x4 arcmin field-of-view, and are roughly uniformly distributed over the sky, making them suitable for a homogeneous broadband calibration network for near-infrared panoramic detectors. K magnitudes range from 8.5 to 14, and J-K colors from -0.1 to 1.2. The photometry is derived from a total of 3899 reduced images; each star has been measured, on average, 26.0 times per filter on 5.5 nights. Typical errors on the photometry are about 0.012.

description: We investigate possible existence of duality symmetries which exchange the Kaluza-Klein modes with the wrapping modes of a BPS saturated $p$-brane on a torus. Assuming the validity of the conjectured $U$-duality symmetries of type II and heterotic string theories and $M$-theory, we show that for a BPS saturated $p$-brane there is an SL(2,Z) symmetry that mixes the Kaluza-Klein modes on a $(p+1)$ dimensional torus $T^{(p+1)}$ with the wrapping modes of the $p$-brane on $T^{(p+1)}$. The field that transforms as a modular parameter under this SL(2,Z) transformation has as its real part the component of the $(p+1)$-form gauge field on $T^{(p+1)}$, and as its imaginary part the volume of $T^{(p+1)}$, measured in the metric that couples naturally to the $p$-brane.

Supersymmetric phases of finite-temperature strings II

description: It was recently proposed that there exist stable supersymmetric phases for finite temperature superstings. This issue was investigated using an effective supergravity which takes into account massive winding modes. Such a theory admits BPS solutions that do not suffer from Hagedorn-type instabilities. We extend several aspects of this work. First we restrict to the real-field sector of the theory and allow, in general, for unequal right and left winding fields. Then, by further specializing to type-II theories (IIA, IIB and a self-dual hybrid) we construct the most general 1/2-BPS solution and reveal several new features arising in various consistent truncations. In the heterotic case we investigate the general properties of the solution which is presented in a closed form in the limit of infinitely large left-winding field.

description: Autonomous drone racing competitions are a proxy to improve unmanned aerial vehicles' perception, planning, and control skills. The recent emergence of autonomous nano-sized drone racing imposes new challenges, as their ~10cm form factor heavily restricts the resources available onboard, including memory, computation, and sensors. This paper describes the methodology and technical implementation of the system winning the first autonomous nano-drone racing international competition: the IMAV 2022 Nanocopter AI Challenge. We developed a fully onboard deep learning approach for visual navigation trained only on simulation images to achieve this goal. Our approach includes a convolutional neural network for obstacle avoidance, a sim-to-real dataset collection procedure, and a navigation policy that we selected, characterized, and adapted through simulation and actual in-field experiments. Our system ranked 1st among seven competing teams at the competition. In our best attempt, we scored 115m of traveled distance in the allotted 5-minute flight, never crashing while dodging static and dynamic obstacles. Sharing our knowledge with the research community, we aim to provide a solid groundwork to foster future development in this field.

Effect of time varying transmission rates on coupled dynamics of epidemic and awareness over multiplex network

description: In the present work, a non-linear stochastic model is presented to study the effect of time variation of transmission rates on the co-evolution of epidemics and its corresponding awareness over a two layered multiplex network. In this model, the infection transmission rate of a given node in the epidemic layer depends upon its awareness probability in the awareness layer. Similarly, the infection information transmission rate of a node in the awareness layer depends upon its infection probability in the epidemic layer. The spread of disease resulting from physical contacts is described in terms of SIS (Susceptible Infected Susceptible) process over the epidemic layer and the spread of information about the disease outbreak is described in terms of UAU (Unaware Aware Unaware) process over the virtual interaction mediated awareness layer. The time variation of the transmission rates and the resulting co-evolution of these mutually competing processes is studied in terms of a network topology depend parameter(α). Using a second order linear theory it has been shown that in the continuous time limit, the co-evolution of these processes can be described in terms of damped and driven harmonic oscillator equations. From the results of the Monte-Carlo simulation, it is shown that for the suitable choice of parameter(α), the two process can either exhibit sustained oscillatory or damped dynamics. The damped dynamics corresponds to the endemic state. Further, for the case of endemic state it is shown that the inclusion of awareness layer significantly lowers the disease transmission rate and reduces the size of epidemic. The endemic state infection probability of a given node corresponding to the damped dynamics is found to have dependence upon both the transmission rates as well as on both absolute intra-layer and relative inter-layer degree of the individual nodes.

description: Electroencephalography (EEG) signals are easily corrupted by various artifacts, making artifact removal crucial for improving signal quality in scenarios such as disease diagnosis and brain-computer interface (BCI). In this paper, we present a fully convolutional neural architecture, called DTP-Net, which consists of a Densely Connected Temporal Pyramid (DTP) sandwiched between a pair of learnable time-frequency transformations for end-to-end electroencephalogram (EEG) denoising. The proposed method first transforms a single-channel EEG signal of arbitrary length into the time-frequency domain via an Encoder layer. Then, noises, such as ocular and muscle artifacts, are extracted by DTP in a multi-scale fashion and reduced. Finally, a Decoder layer is employed to reconstruct the artifact-reduced EEG signal. Additionally, we conduct an in-depth analysis of the representation learning behavior of each module in DTP-Net to substantiate its robustness and reliability. Extensive experiments conducted on two public semi-simulated datasets demonstrate the effective artifact removal performance of DTP-Net, which outperforms state-of-art approaches. Experimental results demonstrate cleaner waveforms and significant improvement in Signal-to-Noise Ratio (SNR) and Relative Root Mean Square Error (RRMSE) after denoised by the proposed model. Moreover, the proposed DTP-Net is applied in a specific BCI downstream task, improving the classification accuracy by up to 5.55% compared to that of the raw signals, validating its potential applications in the fields of EEG-based neuroscience and neuro-engineering.

description: Diese Richtlinie ergänzt DIN 51309:2005-12 um die Kalibrierung von Drehmomentmessgeräten mit Wechseldrehmoment. Drehmomentaufnehmer, die für quasistatische Anwendungen mit Wechseldrehmomentbelastung vorgesehen sind, werden auch quasistatisch mit Wechseldrehmoment kalibriert. Für eine effiziente Gewinnung der Wechseldrehmomentkalibrierkurve aus den Kurven für die einfache Rechts- und Linksdrehmomentkalibrierung werden Vorschläge diskutiert. Die Hysterese im Nullpunkt, welche mechanische Remanenz genannt wird, gibt Aufschluss über die Messunsicherheit bei Wechseldrehmomentbelastung und damit über die Eignung eines Aufnehmers für diesen Anwendungsfall. Im Allgemeinen werden bei der Verwendung eines solchen Aufnehmers keine Untersuchungen zur Lage des Nullpunktes, auf den sich die Messergebnisse beziehen, durchgeführt. Dies führt dazu, dass mit dem doppelten Wert der bei der Wechseldrehmomentkalibrierung bestimmten Hysterese gerechnet werden muss.
A perturbative renormalization group approach to light-front Hamiltonian

Year: 1995
Subjects: subject: High Energy Physics - Theory (hep-th)

description: A perturbative renormalization group (RG) scheme for light-front Hamiltonian is formulated on the basis of the Bloch-Horowitz effective Hamiltonian, and applied to the simplest $ϕ^4$ model with spontaneous breaking of the $Z_2$ symmetry. RG equations are derived at one-loop order for both symmetric and broken phases. The equations are consistent with those calculated in the covariant perturbation theory. For the symmetric phase, an initial cutoff Hamiltonian in the RG procedure is made by excluding the zero mode from the canonical Hamiltonian with an appropriate regularization. An initial cutoff Hamiltonian for the broken phase is constructed by shifting $ϕ$ as $ϕ\rightarrowϕ-v$ in the initial Hamiltonian for the symmetric phase. The shifted value $v$ is determined on a renormalization trajectory. The minimum of the effective potential occurs on the trajectory.

description: Polymer microfiber electret filters are the technology behind N95 and equivalent type respirators. Understanding how liquids interact with and discharge these filters would allow for the development of non-damaging liquid decontamination protocols. Previous work on liquid/filter interactions has been largely empirical with articles reporting the effect a specific liquid has on the filtration efficiency of a particular filter. This thesis proposes a theoretical model of liquid induced discharge of polymer microfiber electret filters via the ideas of surface wetting and electrical conductivity. This model was tested, and validated, on commercially available polypropylene microfiber electret filters through wetting, thermally stimulated discharge (TSD), and filtration experiments.
