description: We present a method using the SALT2 light curve fitter to determine the redshift of Type Ia supernovae in the Supernova Legacy Survey (SNLS) based on their photometry in g', r', i' and z'. On 289 supernovae of the first three years of SNLS data, we obtain a precision $σ_{Δz/(1+z)} = 0.022$ on average up to a redshift of 1.0, with a higher precision of 0.016 for z<0.45 and a lower one of 0.025 for z>0.45. The rate of events with $|Δz|/(1+z)>0.15$ (catastrophic errors) is 1.4%. Both the precision and the rate of catastrophic errors are better than what can be currently obtained using host galaxy photometric redshifts. Photometric redshifts of this precision may be useful for future experiments which aim to discover up to millions of supernovae Ia but without spectroscopy for most of them.

description: Conidiobolomycosis (rhinofacial entomophthoromycosis) in Gabon. About of one case


Background. Entomophthoromycosis constitutes a nosological group of subcutaneous mycoses including conidiobolomycosis (rhinofacial form) and basidiobomomycosis (subcutaneous form involving the trunk and the limbs). Conidiobolomycosis is characterized by a progressive nasal and facial deformity giving, in the evolved forms, a “hippopotamus snout”. The literature review finds a hundred cases, with a tropism for the humid tropical regions.


Methods. We report the observation of a 25-year-old patient, living in the equatorial zone, in the south of Gabon in a humid forest area, presenting a swollen aspect of the face mainly involving the eyelids, the nose and the upper lips.


Results. The diagnosis of entomophthoromycosis was compatible with the histopathological and clinical aspects. The evolution was favorable in terms of facial aesthetics under itraconazole 300 mg/day for 2 months and corticosteroid therapy (bolus of methylprednisone 240 mg/day for 3 days relayed per os at a dose of 0.5 mg/kg/day, i.e. 30 mg/day) of prednisone), maintained for 3 months. The average nasal improvement could not be completed by surgery and the patient was lost to follow-up.


Conclusion. This second observation of conidiobolomycosis in Gabon in the same province makes Ngounié a privileged ecosystem for this affection.


Conidiobolomycose (entomophthoromycose rhinofaciale) au Gabon, à propos d’une observation


Introduction. La conidiobolomycose ou entomophthoromycose rhinofaciale est une mycose sous-cutanée tropicale rare, réalisant dans les formes évoluées un aspect dysmorphique, typique, du visage en « museau d’hippopotame », dont peu de cas ont été rapportés dans la littérature.


Méthodologie. Nous présentons l’observation d’un patient de 25 ans, vivant en zone équatoriale, au sud du Gabon en environnement forestier humide.


Résultats. Les données histologiques de la biopsie cutanée associées à la présentation clinique étaient compatibles avec le diagnostic de conidiobolomycose. L’évolution initiale était favorable sur le plan es-thétique sous itraconazole 300 mg/jour pendant 2 mois et corticothérapie (bolus de méthylprednisone 240 mg/jour pendant 3 jours relayée per os à la dose de 0,5 mg/kg/jour (soit 30 mg/jour) de predni-sone), maintenue pendant 3 mois. L’amélioration moyenne nasale n’a pu être complétée par une chirur-gie et le malade a été perdu de vue.


Conclusion. Cette deuxième observation de conidiobolomycose au Gabon dans la même province, fait de la Ngounié, un écosystème privilégié de cette affection.

He reported a history of odynophagia two days before, followed by productive cough, fever and dyspnea. On chest radiography, a line could be observed surrounding the heart and the continuous diaphragm sign. The chest computed tomography scan confirmed the presence of pneumomediastinum and soft tissue emphysema. The case was discussed in a multidisciplinary team, and the possibility of surgical intervention was rejected. Conservative treatment was decided with complete resolution of the pneumomediastinum.

description: One of the aims of next generation optical interferometric instrumentation is to be able to make use of information contained in the visibility phase to construct high dynamic range images. Radio and optical interferometry are at the two extremes of phase corruption by the atmosphere. While in radio it is possible to obtain calibrated phases for the science objects, in the optical this is currently not possible. Instead, optical interferometry has relied on closure phase techniques to produce images. Such techniques allow only to achieve modest dynamic ranges. However, with high contrast objects, for faint targets or when structure detail is needed, phase referencing techniques as used in radio interferometry, should theoretically achieve higher dynamic ranges for the same number of telescopes. Our approach is not to provide evidence either for or against the hypothesis that phase referenced imaging gives better dynamic range than closure phase imaging. Instead we wish to explore the potential of this technique for future optical interferometry and also because image reconstruction in the optical using phase referencing techniques has only been performed with limited success. We have generated simulated, noisy, complex visibility data, analogous to the signal produced in radio interferometers, using the VLTI as a template. We proceeded with image reconstruction using the radio image reconstruction algorithms contained in AIPS IMAGR (CLEAN algorithm). Our results show that image reconstruction is successful in most of our science cases, yielding images with a 4 milliarcsecond resolution in K band. (abridged)

description: Aortoesophageal fistulas are uncommon, dreadful vascular events, most frequently found in the setting of thoracic aorta aneurysms. Patients usually present with thoracic pain, dysphagia and sentinel hematemesis - the Chiari triad - followed by life threatening hematemesis. Emergent open surgery with debridement of necrotic tissue and in situ aortic graft repair is currently the best strategy. However, in patients which cannot withstand surgery, endovascular repair is currently gaining acceptance as a palliative treatment or as a bridge to surgery. We present a case of a 55-year-old female with a past of heavy alcohol abuse and a previously unknown massive aortic aneurysm, who presented to the emergency department complaining of acute dysphagia and epigastric pain. An abdominal ultrasound revealed left pleural effusion and suspected clots in the pleural space. A thoracic CTA was promptly done, where a spontaneous ruptured aortic aneurysm with aortoesophageal fistula was discovered. The team, fearing open surgery due to poor cardiac function, opted for a thoracic endovascular aortic repair. The aortoesophageal fistula dissected the esophageal wall in all of its thickness without rupture into the lumen. This was complicated with esophageal ischemia, aneurysmal sac infection and mediastinitis. Because the patient was in shock, in order to help control the infection, an esophageal prosthesis was placed, followed by proximal esophagostomy, distal esophageal closure and gastrostomy. Six months after initial presentation, the patient died at the emergency room, shortly after reentering with massive hematemesis and hypovolemic shock of undetermined origin.

Such a family is predicted by the approach unifying spins and charges as the fifth family. We make a rough estimation of properties of baryons of this new family members and study possible limitations on the family properties due to the direct experimental and the cosmological evidences, studying the cosmological evolution of the fifth family clusters.

Nonlinear Information Filtering for Distributed Multisensor Data Fusion

Publisher: name: Karlsruhe
Year: 2011

description: The information filter has evolved into a key tool for distributed and decentralized multisensor estimation and control. Essentially, it is an algebraical reformulation of the Kalman filter and provides estimates on the information about an uncertain state rather than on a state itself. Whereas many practicable Kalman filtering techniques for nonlinear system and sensor models have been developed, approaches towards nonlinear information filtering are still scarce and limited. In order to deal with nonlinear systems and sensors, this paper derives an approximation technique for arbitrary probability densities that provides the same distributable fusion structure as the linear information filter. The presented approach not only constitutes a nonlinear version of the information filter, but it also points the direction to a Hilbert space structure on probability densities, whose vector space operations correspond to the fusion and weighting of information.
Experimental investigation of nonlinear coupled vibrations of bars and plates
Creators: name: Schneider, Bernd C.
Publisher: name: University of British Columbia
Year: 2011

description: The theory presented describes the physical phenomenon of nonlinear coupling of longitudinal and flexural vibrations when a beam is excited transversely at high frequencies. Equations are derived based on the Bernoulli-Euler theory of flexure, by energy methods, to describe the transverse and the longitudinal vibration of a beam of constant cross-section under plane motion. The initial crookedness of the beam and the longitudinal inertia, accounted for in the theory, give rise to the coupled vibrations. No closed form solution is presented. However, a simple analysis of some of the coupling terms suggests the existence of several coupled vibrations. By the method proposed herein, the frequencies of these vibrations can be established. In particular, the theory predicts two longitudinal coupled vibrations with the frequency ratio 1:2. The agreement between the theory and the experimental results is good. The vibrations predicted exist and the frequency ratio for the predicted longitudinal vibrations was 1:2. Further, the experimental results indicate that there are more longitudinal vibrations than indicated by the theory. A longitudinal coupled vibration at three times the frequency of transverse excitation was recorded. There are indications in the data that coupled flexural vibrations at twice the frequency of transverse excitation exist. A circular plate centrally supported and transversely excited was also tested. Two pronounced resonant radial vibrations were recorded. The frequency ratio was 1:2. Coupled flexural vibrations were not identified. The influence of the longitudinal vibration on the flexural vibration of the beam is examined. The limitations of the theory, of the experiment, and the significance of the resonant strains is discussed.
NEW ORAL ANTICOAGULANTS (NOACS) ARE THE GOLD STANDARD IN VENOUS THROMBOEMBOLISM

description: Introduction: Venous Thromboembolism (VTE) is an important cause of morbidity and mortality. The risk of recurrence could be very high without thromboprophylaxis. New oral anticoagulants (NOACs or DOACs) represent a new step in anticoagulation. Material and Methods: We searched for papers with trials, systematic reviews and meta-analysis involving NOACs in the treatment and secondary prevention of VTE. We also searched for guidelines of two medical societies (American College of Chest Physicians and International Society of Thrombosis and Haemostasis - ISTH). Results: Six RCT (randomized controlled trial) comparing NOACs with Warfarin shew a non-inferiority in relation with recurrent VTE and major bleeding. Two RCT (SELECT-D and Hokusay cancer) and one meta-analysis shew low recurrence rate of VTE in cancer patients and higher rate of bleeding, mainly in gastrointestinal and genitourinary cancers. There are two RCTs involving NOACs in treatment of patients with Antiphospholipid Syndrome (APS). Discussion: NOACs shew non-inferiority over AVK. Guidelines of CHEST 2016 recommend NOACs for VTE treatment in no cancer patients, and Low Molecular Weight Heparin (LMWH) for cancer patients. ISTH suggest NOACs as the first option in VTE cancer patients with low risk of bleeding. A recent RCT shews no benefit and increased risk of vascular events in APS patients treated with NOACs. NOACs are the gold standard for VTE treatment and secondary prevention in no cancer patients. They could be the first option in cancer patients with low risk of bleeding.

On ergodic two-armed bandits

Publisher: name: arXiv
Year: 2009
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: A device has two arms with unknown deterministic payoffs and the aim is to asymptotically identify the best one without spending too much time on the other. The Narendra algorithm offers a stochastic procedure to this end. We show under weak ergodic assumptions on these deterministic payoffs that the procedure eventually chooses the best arm (i.e., with greatest Cesaro limit) with probability one for appropriate step sequences of the algorithm. In the case of i.i.d. payoffs, this implies a "quenched" version of the "annealed" result of Lamberton, Pagès and Tarrès [Ann. Appl. Probab. 14 (2004) 1424--1454] by the law of iterated logarithm, thus generalizing it. More precisely, if $(η_{\ell,i})_{i\in \mathbb {N}}\in\{0,1\}^{\mathbb {N}}$, $\ell\in\{A,B\}$, are the deterministic reward sequences we would get if we played at time $i$, we obtain infallibility with the same assumption on nonincreasing step sequences on the payoffs as in Lamberton, Pagès and Tarrès [Ann. Appl. Probab. 14 (2004) 1424--1454], replacing the i.i.d. assumption by the hypothesis that the empirical averages $\sum_{i=1}^nη_{A,i}/n$ and $\sum_{i=1}^nη_{B,i}/n$ converge, as $n$ tends to infinity, respectively, to $θ_A$ and $θ_B$, with rate at least $1/(\log n)^{1+\varepsilon}$, for some $\varepsilon >0$. We also show a fallibility result, that is, convergence with positive probability to the choice of the wrong arm, which implies the corresponding result of Lamberton, Pagès and Tarrès [Ann. Appl. Probab. 14 (2004) 1424--1454] in the i.i.d. case.

Networked silence : political dissent in a digital era

description: Over the past few decades, partisans have ideologically and emotionally polarized as partisanship has become increasingly aligned with social identity and geographic location. Existing theory suggests that this would make expressing a dissenting political opinion especially hard. Yet individuals now have more choice in the communities in which they express their opinions. With the rise of digital media, people today can be a part of multiple communities. Moreover, digital technology has afforded backchannels that make political expression not only more networked, but also more private. Despite these changes, much of the scholarship on opinion expression has continued conceptualizing expression as dichotomous; as either public expression or total silence. This dissertation poses a new theory of opinion expression combining two traditions: spiral of silence and networked individualism. I advance a theory of networked silence that suggests instead of remaining silent, individuals, empowered by network choice and the private affordances of digital technology, individuals may be silent in one context but expressive in another. Through in-depth interviews with and field observations of a secret political organization in rural Texas, I uncover why people feel the need to hide their political beliefs and where they go to express them intentionally in private. Through representative survey data, I find that networked silence is happening at a larger-scale across the United States and Texas. The evidence in this dissertation tells a different story about political communication than what is currently told. It suggests that portions of the public may be silent in one context but are not silent altogether; may care about politics but are afraid of making that concern public. As the public becomes increasingly polarized and sorted, and as digital media expands the ability for individuals to communicate and organize in secret, the potential and scope of networked silence becomes both more likely and more probable, not just for those with extreme beliefs, but for those in the mainstream as well. Understanding the existence and effects of networked silence can help both scholars and practitioners engage portions of the electorate for whom publicly engaging in politics may feel especially risky.

description: We consider a fractal with a variable fractal dimension, which is a generalization of the well known triadic Cantor set. In contrast with the usual Cantor set, the fractal dimension is controlled using a scaling factor, and can vary from zero to one in one dimension and from zero to three in three dimensions. The intensity profile of small-angle scattering from the generalized Cantor fractal in three dimensions is calculated. The system is generated by a set of iterative rules, each iteration corresponding to a certain fractal generation. Small-angle scattering is considered from monodispersive sets, which are randomly oriented and placed. The scattering intensities represent minima and maxima superimposed on a power law decay, with the exponent equal to the fractal dimension of the scatterer, but the minima and maxima are damped with increasing polydispersity of the fractal sets. It is shown that for a finite generation of the fractal, the exponent changes at sufficiently large wave vectors from the fractal dimension to four, the value given by the usual Porod law. It is shown that the number of particles of which the fractal is composed can be estimated from the value of the boundary between the fractal and Porod regions. The radius of gyration of the fractal is calculated analytically.

description: In this work, we propose a plenhaptic guidance function that systematically describes the haptic information for guiding the user in the target environment. The plenhaptic guidance function defines the strength of the guidance at any position in space, at any direction, and at any time, and takes the geometry of the target environment as well as all possible goals into account. The plenhaptic guidance function, which can be rendered as active and passive guidance, is sampled and displayed to the user through a haptic interface in the user environment. The benefits of the plenhaptic guidance function for guiding the user to several simultaneous goals while avoiding the obstacles in a large target environment are demonstrated in real experiments.

description: Background: Complex pathology of the Thoracic Aorta constitutes a challenge, needing a complex and multidisciplinary approach. The hybrid stent graft prosthesis E-vita OPEN PLUS™ avoids a two-stage surgical approach in the surgical treatment of complex thoracic aortic disease. The E-vita Open Plus™ is estimated to generate cost savings compared with current two-stage repair from about 2 years after the procedure. Methods: Between February 2017 and July 2019, a total of 6 patients, underwent one stage surgery for treatment of multisegmental thoracic aortic disease with hybrid stent graft prosthesis E-vita OPEN PLUS™ We collected the data from our records and compared them to the International E-vita Open Registry (IEOR), regarding ischemic and operative times as well as adverse events monitored during follow-up. Results/Discussion: The average patient age was 56 years (range: 36-76 years). The average Cardiopulmonary Bypass, Aortic Cross Clamping and Circulatory Arrest times where 204, 86 and 63 minutes respectively. The recovery after procedure had fewer complications and the length stay was less than described in literature. There was no in-hospital mortality. In all patients there was a reduction of aneurysm sac size and positive aortic remodeling and all where asymptomatic in regard to cardiovascular symptoms. Conclusions: The use of E-vita OPEN PLUS™ seems a safe and efficient option for patients with complex aortic arch pathology. In our experience, surgery allowed treatment of extensive thoracic aortic diseases with satisfactory short- and mid-term results.

description: We present an auction-flavored multi-robot planning mechanism where coordination is to be achieved on the occupation of atomic resources modeled as binary inter-robot constraints. Introducing virtual obstacles, we show how this approach can be combined with particlebased obstacle avoidance methods, offering a decentralized, auction-based alternative to previously established centralized approaches for multirobot open-loop control. We illustrate the effectiveness of our new approach by presenting simulations of typical spatially-continuous multirobot path-planning problems and derive bounds on the collision probability in the presence of uncertainty.

description: A common problem, arising in many different applied contexts, consists in estimating the number of exponentially damped sinusoids whose weighted sum best fits a finite set of noisy data and in estimating their parameters. Many different methods exist to this purpose. The best of them are based on approximate Maximum Likelihood estimators, assuming to know the number of damped sinusoids, which can then be estimated by an order selection procedure. As the problem can be severely ill posed, a stochastic perturbation method is proposed which provides better results than Maximum Likelihood based methods when the signal-to-noise ratio is low. The method depends on some hyperparameters which turn out to be essentially independent of the application. Therefore they can be fixed once and for all, giving rise to a black box method.

description: Abstract

This paper studies the main factors affecting restaurants’ customer satisfaction by examining the combination of the effects of physical environments in Saudi Arabia. Therefore, the present study raises interesting conclusions with significant theoretical and practical implications. By using a well-designed questionnaire as a measurement tool for this work, the sampling space is the casual dining restaurant community in Jeddah, Saudi Arabia. Twenty questions were listed in the questionnaire asking about the restaurants’ physical environmental factors such as lighting, facility aesthetics, table setting, and layout on customer satisfaction. Six different styles of restaurants were selected to conduct the survey. The results have been analysed and compared using different statistical software packages. The study found that Lighting is the essential factor for customer satisfaction by 76.1%, besides the importance of facility aesthetics, table setting, and layout, respectively. At the same time, the background music was the least important factor by 65.8%.

description: Interference between different energy eigenstates in a quantum system results in an oscillation with a frequency which is proportional to the difference in energy between the states. Such an oscillation is observable in polarized positronium when it is placed in a magnetic field. In order to measure the hyperfine splitting of positronium, we perform the precise measurement of this oscillation using a high quality superconducting magnet and fast photon-detectors. A result of $203.324 \pm 0.039\rm{~(stat.)} \pm 0.015\rm{(~sys.)}$~GHz is obtained which is consistent with both theoretical calculations and previous precise measurements.

Molecular rheology of coniferous wood tissues
Creators: name: Chow, Sue-Zone
Publisher: name: University of British Columbia
Year: 2011

description: The time dependent molecular motions of wood components at straining parallel to fibre direction were observed by infrared polarization technique. A two-stage molecular motion involving three wood components, cellulose, hemicellulose and lignin is suggested as the course of wood molecular relaxation. The first stage begins at equilibrium, when the specimen is not stressed, and extends immediately to a minimum dichroic ratio (formula omitted) of carbo-hydrate components represented by 1160 cm⁻¹ and 1730 cm⁻¹ bands, and the maximum dichroism of lignin (1500 cm⁻¹). The second stage starts at the end of the first stage and extends to equilibrium recovery. Regardless of the form of external excitation (creep or stress relaxation), and the time of excitation (ramp- or step-loading), the basic pattern of the two-stage molecular motion was followed, while damping of the molecules accompanied the whole rheological process. Thus, the wood macromolecular structure maintains an "internal state" of equilibrium on receiving external excitation. This equilibrium state is achieved by moving the carbohydrate and lignin components in opposite directions. The described pattern of molecular motion for a component in wood is a compensatory result from the interference of other components. Removing one or more components from wood changes the motion patterns of the remaining components. The conformation of cellulose in the specimen without the presence of lignin and hemicellulose is comparable to that of other synthetic linear polymers. Energy transfer system of wood was postulated as being due to the directional movement of molecular components which results in association and high steric interference between carbohydrates and lignin, similar to cross-linked chains of lignin and carbohydrates. This energy transfer system of wood is further facilitated by the existence of a systematic structure of wood microfibrils which permits a zone of gradual transition from high crystallinity to a diffuse state. The lignin network of the system may do more than transfer energy, it may act also as an "energy sink" and thereby function to maintain the memory of the excitation.

description: Green's function Monte Carlo calculations of magnetic moments and M1 transitions including two-body meson-exchange current (MEC) contributions are reported for A<=7 nuclei. The realistic Argonne v18 two-nucleon and Illinois-2 three-nucleon potentials are used to generate the nuclear wave functions. The two-body meson-exchange operators are constructed to satisfy the continuity equation with the Argonne v18 potential. The MEC contributions increase the A=3,7 isovector magnetic moments by 16% and the A=6,7 M1 transition rates by 17--34%, bringing them into very good agreement with the experimental data.

Year: 2009
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: According to quantum chromodynamics, matter at ultra-high density and low temperature is a quark liquid, with a condensate of Cooper pairs of quarks near the Fermi surface ("color superconductivity"). This paper reviews the physics of color superconductivity, and discusses some of the proposed signatures by which we might detect quark matter in neutron stars.

description: In this paper, the localization of persons by means of a Wireless Sensor Network (WSN) is considered. Persons carry on-body sensor nodes and move within a WSN. The location of each person is calculated on this node and communicated through the network to a central data sink for visualization. Applications of such a system could be found in mass casualty events, firefighter scenarios, hospitals or retirement homes for example. For the location estimation on the sensor node, three derivatives of the Kalman Filter and a closed-form solution (CFS) are applied, compared, and evaluated in a real-world scenario. A prototype 65-node ZigBee WSN is implemented and data are collected in in- and outdoor environments with differently positioned on-body nodes. The described estimators are then evaluated off-line on the experimentally collected data. The goal of this paper is to present a comprehensive real-world evaluation of methods for person localization in a WSN based on received signal strength (RSS) range measurements. It is concluded that person localization in in- and outdoor environments is possible under the considered conditions with the considered filters. The compared methods allow for suffciently accurate localization results and are robust against inaccurate range measurements.
Vacuum Stability of the $\mathcal{PT}$-Symmetric $\left( -ϕ^{4}\right) $ Scalar Field Theory

description: In this work, we study the vacuum stability of the classical unstable $\left( -ϕ^{4}\right) $ scalar field potential. Regarding this, we obtained the effective potential, up to second order in the coupling, for the theory in $1+1$ and $2+1$ space-time dimensions. We found that the obtained effective potential is bounded from below, which proves the vacuum stability of the theory in space-time dimensions higher than the previously studied $0+1$ case. In our calculations, we used the canonical quantization regime in which one deals with operators rather than classical functions used in the path integral formulation. Therefore, the non-Hermiticity of the effective field theory is obvious. Moreover, the method we employ implements the canonical equal-time commutation relations and the Heisenberg picture for the operators. Thus, the metric operator is implemented in the calculations of the transition amplitudes. Accordingly, the method avoids the very complicated calculations needed in other methods for the metric operator. To test the accuracy of our results, we obtained the exponential behavior of the vacuum condensate for small coupling values, which has been obtained in the literature using other methods. We assert that this work is interesting, as all the studies in the literature advocate the stability of the $\left( -ϕ^{4}\right) $ theory at the quantum mechanical level while our work extends the argument to the level of field quantization.

The making of Under the Volcano : an examination of lyrical structure, with reference to textual revisions
Creators: name: Johnson, Carell
Publisher: name: University of British Columbia
Year: 2011

description: The aim of this thesis is to investigate how Lowry expanded Under the Volcano beyond the narrative level and yet also managed to infuse this dense, expanded structure with an organic unity. Passages from the earlier drafts of the novel have been juxtaposed with the printed version in order to reveal salient aspects of method and purpose in the novel's composition. Chapter I attempts to demonstrate that Under the Volcano is essentially a lyrical novel and discusses the background and aims of this twentieth century genre. What chiefly distinguishes the lyrical from the non-lyrical novel is that it transcends chronological time, to some degree, and presents a spatial pattern. Chapter II discusses the cosmic outlook which prompts a writer to aim at presenting simultaneity rather than succession, and examines textual revisions which reveal Lowry's intention to give his theme a cosmic or universal scope. Chapter III examines how Lowry has expanded moments in the narrative through the use of leitmotif. In tracing these flexible motifs, we see that Lowry has used variation to make one symbol or image embrace both positive and negative poles and thus render his central theme, the dichotomy of human experience. Chapter IV traces how Lowry has used another musical device, counterpoint, to expand moments or scenes in the narrative and thus suggest simultaneity. The final chapter discusses the prevailing atmosphere of poised tension and the wave pattern which emerge from the novel's structure and how this pattern not only gives the expanded structure a unity, but also renders theme.

Hänsch--Couillaud locking of Mach--Zehnder interferometer for carrier removal from a phase-modulated optical spectrum

description: We describe and analyse the operation and stabilization of a Mach--Zehnder interferometer, which separates the carrier and the first-order sidebands of a phase-modulated laser field, and which is locked using the Hänsch--Couillaud method. In addition to the necessary attenuation, our interferometer introduces, via total internal reflection, a significant polarization-dependent phase delay. We employ a general treatment to describe an interferometer with an object which affects the field along one path, and we examine how this phase delay affects the error signal. We discuss the requirements necessary to ensure the lock point remains unchanged when phase modulation is introduced, and we demonstrate and characterize this locking experimentally. Finally, we suggest an extension to this locking strategy using heterodyne detection.
