description: It is well-known that the standard no-ghost theorem can be extended straightforwardly to the general c=26 CFT on R^{d-1,1} \times K, where 2 \leq d \leq 26 and K is a compact unitary CFT of appropriate central charge. We prove the no-ghost theorem for d=1, i.e., when only the timelike direction is flat. This is done using the technique of Frenkel, Garland and Zuckerman.

description: Phytosterols are one of the bioactive components responsible for the beneficial effects of Serenoa repens in Benign Prostate Hyperplasia. The aim of this study was to verify the actual variability of the phytosterols content in supplements containing serenoa, in order to provide useful elements to check the effectiveness of these preparations. The amount of campesterol, stigmasterol and β-sitosterol were determined by gas-chromatography in commercial raw materials and supplements containing serenoa in association or not with other botanicals. The experimental data were used to calculate amounts of phytosterols for recommended daily dose. The overall results of this study show an extreme variability in the content and also in the amounts per daily dose of phytosterols of the examined supplements (both mono/multi components). These data confirm that the characterization of serenoa based supplements is insufficient to ensure comparable effects between different products.

description: Social media platforms allow politicians to communicate to and with their followers directly, without the interference of news media professionals. Political actors have eagerly adopted these platforms, which arguably makes them less dependent on traditional news media for their political communication. Still, they rely on the authority and trustworthiness of traditional outlets when they share news on their online platforms. In this paper, we research politicians’ online news sharing behavior in three countries by studying which politicians share news, which outlets published the news they share, and which news management strategies they employ when sharing news online. Results show that government party politicians share less news than opposition members, radical right-wing politicians share more news published by alternative news outlets, and government and opposition politicians use different news management strategies when sharing news online. We conclude that politicians’ online news sharing is a strategic practice and could have serious implications for partisan selective exposure in the digital information environment.

description: This document describes major tasks that utilize multi-disciplinary scientific processes to investigate archaeological and cultural sensitivities on the largest training range in the Air Force with fighter pilot training beginning in the 1950’s. The project is one of two evaluation phases that wIII be concurrently implemented. Part I concentrates geomorphological and archaeological investigations into seven major target construction and use zones, with the results to be subjected to consultation under Section 106 of the National Historic Preservation Act (NHPA). The objectives are to define or limit future inventory in high-impact, low-elevation areas that are shown through archaeological survey to have relatively low potential to locate historic properties. Part II, consists of archaeological research in zones not slated for disturbance in support of the target disturbance zone evaluations and wIII also address Section 110 of NHPA that requires federal institutions take efforts to locate and preserve eligible properties on all lands regardless of future plans for disturbance. The two phases compose a novel, holistic-planned event that is likely the largest compliance and scientific endeavor ever undertaken in the Great Basin, or the West.

description: We compute completely the BRST--antibracket cohomology on local functionals in two-dimensional Weyl invariant gravity for given classical field content (two dimensional metric and scalar matter fields) and gauge symmetries (two dimensional diffeomorphisms and local Weyl transformations). This covers the determination of all classical actions, of all their rigid symmetries, of all background charges and of all candidate gauge anomalies. In particular we show that the antifield dependence can be entirely removed from the anomalies and that, if the target space has isometries, the condition for the absence of matter field dependent Weyl anomalies is more general than the familiar `dilaton equations'.

Forever Young: High Chromospheric Activity in M subdwarfs
Creators: name: Gizis, John E.
Publisher: name: arXiv
Year: 1998
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present spectroscopic observations of two halo M subdwarfs which have H alpha emission lines. We show that in both cases close companions are the most likely cause of the chromospheric activity in these old, metal-poor stars. We argue that Gl 781 A's unseen companion is most likely a cool helium white dwarf. Gl 455 is a near-equal-mass M subdwarf (sdM) system. Gl 781 A is rapidly rotating with v sin i = 30 km/s. The properties of the chromospheres and X-ray coronae of these systems are compared to M dwarfs with emission (dMe). The X-ray hardness ratios and optical chromospheric lines emission ratios are consistent with those seen in dMe stars. Comparison to active near-solar metallicity stars indicates that despite their low metallicity ([m/H] = -1/2), the sdMe stars are roughly as active in both X-rays and chromospheric emission. Measured by L_X/L_bol, the activity level of Gl 781 A is no more than a factor of 2.5 subluminous with respect to near-solar metallicity stars.

description: The U.S. Air Force proposes to construct an underground fiber optic line to the P-49 facility. The proposed route is from the existing P-4 7 fiber optic line at the south base of HIII 5626, follows along a two-track road circling the hIII to a transformer at the east base of the hIII, and then along an existing powerline to the P-49 facility. The reconnaissance consisted of two parallel transects following along the route around the hIII. The section from the transformer to the P-49 facility was not inspected because the proposed fiber optic line is to be placed in a disturbed zone next to the existing powerline. No cultural resources were found during this reconnaissance. The project will have no effects on known historic properties provided all construction activities are restricted to the area inspected and the disturbed portions of the existing powerline.
Cardiovascular magnetic resonance and iron measurement
Creators: name: Carpenter, John-Paul
Publisher: name: Imperial College London
Year: 2011

description: INTRODUCTION: The magnetic resonance (MR) relaxation parameter T2* is used for non-invasive assessment of cardiac iron, with low cardiac T2* being associated with left ventricular (LV) impairment and the development of heart failure. However, there is very little data calibrating cardiac T2* and other MR relaxation parameters to human cardiac iron concentration, and the effects of cardiac iron on the right ventricle (RV) are little known. METHODS AND RESULTS: We studied the distribution of cardiac iron in a series of post-mortem hearts from transfusion-dependent patients using mass spectrometry derived iron concentration, and compared the results against the MR relaxation parameters T1, T2 and T2*. We found variable iron loading between cardiac tissues, but a mainly homogeneous deposition of iron in the LV myocardium, apart from a transmural gradient. We established a calibration equation for cardiac iron using T2*. Septal iron and T2* were very representative of whole-heart values. Cardiac iron was also measurable using T2, but T1 measurement was unreliable. Clinical studies of the RV showed a progressive fall in ejection fraction (EF) as iron loading increased and we established normal ranges for RV volumes and EF in patients with beta thalassaemia major (TM). Finally, a worldwide survey of the clinical use of T2* in over 3000 TM patients showed a high prevalence of cardiac iron loading with large regional variation, and confirmed that low T2* values are associated with heart failure and death. CONCLUSION: In transfusion dependent patients, cardiac iron is deposited variably in the cardiac tissues, but is mainly homogenous in the myocardium and can be calculated from cardiac T2* using the obtained calibration equation. There is similarity in myocardial response to iron loading between the RV and LV. Worldwide data shows a high prevalence of cardiac iron loading, but significant variation suggests that undetermined factors may influence the loading, of which genetic modulation is a prime candidate.

Investigating the Role of Substrate Stiffness on Beta-Catenin Activation in Osteoblasts
Creators: name: Platt, Randall Jeffrey
Publisher: name: Imperial College London
Year: 2011

description: Cells are exposed to a myriad of signals from their microenvironment and the finely tuned processing of these cues regulates cell survival, proliferation, and differentiation. Traditional belief was that only soluble signaling factors governed cell behavior, but more recently, much attention has been focused on the influence of mechanical and topographical cues. Although many landmark observations have been published in this regard, still little is known about the mechanisms behind cell response to physical cues. This work stems from the previously reported observations that beta-catenin, a key cell signaling molecule involved in bone development, is activated by acute mechanical stress. The main aim of this work was to investigate the role of substrate stiffness on beta-catenin activation in osteoblasts. Here, two polyacrylamide gel platforms are adapted that vary in Young's modulus and act as adhesive substrates for cell attachment. Osteoblasts grown on these polyacrylamide gels attach through cross-linked extracellular matrix proteins and 'sense' the underlying stiffness of the substrate and change their intracellular biochemistry accordingly. It was found in this work that the amount of total beta-catenin increases after 24 hours in osteoblasts cultured on tissue culture plastic and polyacrylamide gels of 40 kPa. Moreover, the number of cell-cell contacts directly influences the amount of total beta-catenin. It was also found that osteoblasts grown on higher stiffness substrates have more active beta-catenin and less degraded beta- catenin compared to lower stiffness substrates. The novel findings reported here advance the proposal that beta-catenin is a participant in mechanosensing and also provides a new platform for investigation and further insight into a mechanism of action.

Coded Parity Packet Transmission Method for Two Group Resource Allocation
Creators: name: Ab. Ghani, Hadhrami
Publisher: name: Imperial College London
Year: 2011

description: Gap value control is investigated when the number of source and parity packets is adjusted in a concatenated coding scheme whilst keeping the overall coding rate fixed. Packet-based outer codes which are generated from bit-wise XOR combinations of the source packets are used to adjust the number of both source packets. Having the source packets, the number of parity packets, which are the bit-wise XOR combinations of the source packets can be adjusted such that the gap value, which measures the gap between the theoretical and the required signal-to-noise ratio (SNR), is controlled without changing the actual coding rate. Consequently, the required SNR reduces, yielding a lower required energy to realize the transmission data rate. Integrating this coding technique with a two-group resource allocation scheme renders efficient utilization of the total energy to further improve the data rates. With a relatively small-sized set of discrete data rates, the system throughput achieved by the proposed two-group loading scheme is observed to be approximately equal to that of the existing loading scheme, which is operated with a much larger set of discrete data rates. The gain obtained by the proposed scheme over the existing equal rate and equal energy loading scheme is approximately 5 dB. Furthermore, a successive interference cancellation scheme is also integrated with this coding technique, which can be used to decode and provide consecutive symbols for inter-symbol interference (ISI) and multiple access interference (MAI) mitigation. With this integrated scheme, the computational complexity is signi cantly reduced by eliminating matrix inversions. In the same manner, the proposed coding scheme is also incorporated into a novel fixed energy loading, which distributes packets over parallel channels, to control the gap value of the data rates although the SNR of each code channel varies from each other.

A Computational Investigation of Neural Dynamics and Network Structure
Creators: name: Connor, Dustin Thomas
Publisher: name: Imperial College London
Year: 2011

description: With the overall goal of illuminating the relationship between neural dynamics and neural network structure, this thesis presents a) a computer model of a network infrastructure capable of global broadcast and competition, and b) a study of various convergence properties of spike-timing dependent plasticity (STDP) in a recurrent neural network. The first part of the thesis explores the parameter space of a possible Global Neuronal Workspace (GNW) realised in a novel computational network model using stochastic connectivity. The structure of this model is analysed in light of the characteristic dynamics of a GNW: broadcast, reverberation, and competition. It is found even with careful consideration of the balance between excitation and inhibition, the structural choices do not allow agreement with the GNW dynamics, and the implications of this are addressed. An additional level of competition – access competition – is added, discussed, and found to be more conducive to winner-takes-all competition. The second part of the thesis investigates the formation of synaptic structure due to neural and synaptic dynamics. From previous theoretical and modelling work, it is predicted that homogeneous stimulation in a recurrent neural network with STDP will create a self-stabilising equilibrium amongst synaptic weights, while heterogeneous stimulation will induce structured synaptic changes. A new factor in modulating the synaptic weight equilibrium is suggested from the experimental evidence presented: anti-correlation due to inhibitory neurons. It is observed that the synaptic equilibrium creates competition amongst synapses, and those specifically stimulated during heterogeneous stimulation win out. Further investigation is carried out in order to assess the effect that more complex STDP rules would have on synaptic dynamics, varying parameters of a trace STDP model. There is little qualitative effect on synaptic dynamics under low frequency (< 25Hz) conditions, justifying the use of simple STDP until further experimental or theoretical evidence suggests otherwise.
Light-Front QCD(1+1) Coupled to Adjoint Scalar Matter

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

description: We consider adjoint scalar matter coupled to QCD(1+1) in light-cone quantization on a finite `interval' with periodic boundary conditions. We work with the gauge group SU(2) which is modified to ${\rm{SU(2)/Z_2}}$ by the non-trivial topology. The model is interesting for various nonperturbative approaches because it is the sector of zero transverse momentum gluons of pure glue QCD(2+1), where the scalar field is the remnant of the transverse gluon component. We use the Hamiltonian formalism in the gauge $\partial_- A^+ = 0$. What survives is the dynamical zero mode of $A^+$, which in other theories gives topological structure and degenerate vacua. With a point-splitting regularization designed to preserve symmetry under large gauge transformations, an extra $A^+$ dependent term appears in the current $J^+$. This is reminiscent of an (unwanted) anomaly. In particular, the gauge invariant charge and the similarly regulated $P^+$ no longer commute with the Hamiltonian. We show that nonetheless one can construct physical states of definite momentum which are not {\it invariant} under large gauge transformations but do {\it transform} in a well-defined way. As well, in the physical subspace we recover vanishing {\it expectation values} of the commutators between the gauge invariant charge, momentum and Hamiltonian operators. It is argued that in this theory the vacuum is nonetheless trivial and the spectrum is consistent with the results of others who have treated the large N, SU(N), version of this theory in the continuum limit.

Quaternion-valued nonlinear adaptive filters
Creators: name: Che Ujang, Che Ahmad Bukhari Bin
Publisher: name: Imperial College London
Year: 2012

description: Advances in vector sensor technology have created a need for adaptive nonlinear signal processing in the quaternion domain. The main concern of this thesis lies in the issue of analyticity of quaternion-valued nonlinear functions. The Cauchy-Riemann-Fueter (CRF) conditions determine the analyticity in the quaternion domain which proved too strict to be of any practical use. In order to circumvent this problem, split-quaternion nonlinear functions which are analytic componentwise are commonly employed. However, these functions do not fully capture the correlations between dimensions and are not suitable for real-world applications. To address this, the use of fully quaternion nonlinear functions in the derivation of a completely new class of algorithms which takes into consideration the non-commutative aspect of quaternion product is proposed. These fully quaternion functions satisfy the local analyticity condition (LAC) that guarantees the first-order differentiability of the function. This provides a unifying framework for the derivation of gradient based learning algorithms in the quaternion domain which are shown to have the same generic form as their real- and complex-valued counterparts. Unlike existing approaches, this new class of algorithms derived is suitable for the processing of signals with strong component correlations and is further extended to the recurrent neural network (RNN) architecture. Novel algorithms are also derived to improve the computational complexity of quaternion-valued adaptive filters which could be easily extended to incorporate nonlinear functions. A rigorous mathematical analysis provides a basis for the understanding of the convergence and steady-state performance of the proposed algorithms. Simulations over a range of synthetic and real-world signals support the approach taken in the thesis.
Sensory induced long-lasting modification of spontaneous activity in the somatosensory cortex: electrophysiological and modelling studies
Creators: name: Phoka, Elena
Publisher: name: Imperial College London
Year: 2012

description: Emerging evidence suggests that spontaneous neocortical activity is not merely noise but can be modulated and/or engaged by sensory stimulation. We examined whether naturalistic sensory stimulation can induce specific long-term changes in spontaneous cortical state dynamics in the mouse somatosensory cortex, using both in vivo electrophysiology and modelling. Repetitive, high-frequency multi-whisker stimulation using sandpaper resulted in spontaneous ring rate increase of layer IV and Vb multi-units. The ring rate increase in these layers was sustained for at least 25 minutes following the stimulus. The ring rate increase was accompanied by an increase in layer IV sink amplitude. Increase in spontaneous activity was found also in excitatory single-units in layers IV and Vb. Neither the depth of anaesthesia nor stimulus-induced desynchronization could account for this effect. Finally, we found that elimination of lateral inputs, achieved by trimming away all but the principal whisker, abolished the effect. Single-whisker stimulation resulted in a decrease of activity in layers II/III, IV, Vb and VI, and was accompanied by a decrease in layer IV sink amplitude. In parallel, to study whether Spike-Timing-Dependent-Plasticity (STDP) can explain modifications in spontaneous synaptic dynamics, we developed a biologically inspired large-scale model of rodent barrel layers II, III and IV. Our model consists of approximately 4000 spiking neurons, 1.7 million synapses and 2.2 million dynamical variables. Repetitive sensory stimulation induced long-lasting changes in synaptic weights. The initial state of the network, described by a spontaneous attractor, shifted to a post-stimulus stable state following several repetitions of the same structured stimulation pattern. Furthermore, we found that STDP mediated modifications enabled our network to distinguish between structured and shuffled stimuli. Our experimental and modelling results show that sensory experience induces long-term modification of spontaneous activity in the somatosensory cortex. They suggest that lateral projections and time-dependent plasticity mechanisms play an important role in this process.

description: This study explores the conversational terrain of supportive conversations that vary in person centeredness (PC). Our team transcribed and unitized 223 conversations in which a discloser talked about an upsetting event to a listener trained to exhibit either low (LPC), moderate (MPC), or highly person-centered (HPC) comfort. Each utterance was coded for PC with a modified version of the traditional nine-level hierarchy. HPC-coded turns comprised 24% of HPC conversations, while LPC-coded turns comprised almost half of LPC conversations. Over 95% of turns in MPC conversations were classified as MPC. Additionally, turn-level coding and global ratings of PC differentially predicted outcomes. We discuss the implications of these conversational profiles in the context of how the PC content of conversations might aid in cognitive reappraisal.

Multi-Sensor Data Fusion for Travel Time Estimation
Creators: name: Han, Jiang
Publisher: name: Imperial College London
Year: 2012

description: The importance of travel time estimation has increased due to the central role it plays in a number of emerging intelligent transport systems and services including Advanced Traveller Information Systems (ATIS), Urban Traffic Control (UTC), Dynamic Route Guidance (DRG), Active Traffic Management (ATM), and network performance monitoring. Along with the emerging of new sensor technologies, the much greater volumes of near real time data provided by these new sensor systems create opportunities for significant improvement in travel time estimation. Data fusion as a recent technique leads to a promising solution to this problem. This thesis presents the development and testing of new methods of multi-sensor data fusion for the accurate, reliable and robust estimation of travel time. This thesis reviews the state-of-art data fusion approaches and its application in transport domain, and discusses both of opportunities and challenging of applying data fusion into travel time estimation in a heterogeneous real time data environment. For a particular England highway scenario where ILDs and ANPR data are largely available, a simple but practical fusion method is proposed to estimate the travel time based on a novel relationship between space-mean-speed and time-mean-speed. In developing a general fusion framework which is able to fuse ILDs, GPS and ANPR data, the Kalman filter is identified as the most appropriate fundamental fusion technique upon which to construct the required framework. This is based both on the ability of the Kalman filter to flexibly accommodate well-established traffic flow models which describe the internal physical relation between the observed variables and objective estimates and on its ability to integrate and propagate in a consistent fashion the uncertainty associated with different data sources. Although the standard linear Kalman filter has been used for multi-sensor travel time estimation in the previous research, the novelty of this research is to develop a nonlinear Kalman filter (EKF and UKF) fusion framework which improves the estimation performance over those methods based on the linear Kalman filter. This proposed framework is validated by both of simulation and real-world scenarios, and is demonstrated the effectiveness of estimating travel time by fusing multi-sensor sources.

description: By dimensional reduction of a massive supersymmetric B$\wedge $F theory, a manifestly N=1 supersymmetric completion of a massive antisymmetric tensor gauge theory is constructed in (2+1) dimensions. In the N=1-D=3 superspace, a new topological term is used to give mass for the Kalb-Ramond field. We have introduced a massive gauge invariant model using the Stuckelberg formalism and an abelian topologically massive theory for the Kalb-Ramond superfield. An equivalence of both massive models is suggested. Further, a component field analysis is performed, showing a second supersymmetry in the model.

description: The PA implements the Long Range Study Plan (LRSP), in which an 11 % sample of the NTS wIII be investigated for cultural resources. In accordance with this sampling strategy, sample unit U19ax (Figure 1 & 2) was surveyed by the Desert Research Institute (DRI) for archaeological properties. The U19ax sample unit is an area of 914 m by 579 m (3000 ft x 1900 ft). However, a large part of the sample unit was previous surveyed under the U19an and U19ba projects. Therefore, this U19ax sample unit survey consisted of an area 244 m wide by 305 m long (800 ft x 1000 ft).
