Résumé :

Vibronic coupling between electronic and vibrational states in molecules plays a critical role in most photo-induced phenomena. Many key details about a molecule’s vibronic coupling are hidden in linear spectroscopic measurements, and therefore nonlinear optical spectroscopy methods such as two-dimensional electronic spectroscopy (2D ES) have become more broadly adopted. A single vibrational mode of a molecule leads to a Franck–Condon progression of peaks in a 2D spectrum. Each peak oscillates as a function of the waiting time, and Fourier transformation can produce a spectral slice known as a ‘beating map’ at the oscillation frequency. The single vibrational mode produces a characteristic peak structure in the beating map. Studies of single modes have limited utility, however, because most molecules have numerous vibrational modes that couple to the electronic transition. Interactions or interference among the modes may lead to complicated peak patterns in each beating map. Here, we use lineshape-function theory to simulate 2D ES arising from a system having multiple vibrational modes. The simulations reveal that the peaks in each beating map are affected by all of the vibrational modes and therefore do not isolate a single mode, which was anticipated.

Résumé :

In the gymnostome ciliate Didinium nasutum, swimming behaviour depends upon the cyclic activity of about 3000 cilia. The normal beating mode, resulting in forward swimming of the cell, is characterized by a posteriad effective beat (18 left of the longitudinal axis) at a frequency of approximately 15 Hz. Activation of depolarization-sensitive ciliary Ca2+ channels leads to an increase in intracellular Ca2+ concentration and a change in the beating mode. Following rapid reorientation, the effective stroke is anteriad (24 &deg; right of the longitudinal axis) and the beating frequency is about 26 Hz, resulting in fast backward swimming of the cell. In response to minor depolarizations, and hence small increases in cytoplasmic Ca2+ concentration, the cilia inactivate. Frequency increase and reversal in beat orientation share a single threshold level of membrane potential, since both changes of the beating mode occur simultaneously.

Résumé :

Cilia are small organelles protruding from the cell surface that beat synchronously, producing biological transport. Despite intense research for over a century, the mechanisms underlying ciliary beating are still not well understood. Even the nature of the cytosolic molecules required for spontaneous and stimulated beating is debatable. In an effort to resolve fundamental questions related to cilia beating, we developed a method that integrates the whole-cell mode of the patch-clamp technique with ciliary beat frequency measurements on a single cell. This method enables to control the composition of the intracellular solution while the cilia remain intact, thus providing a unique tool to simultaneously investigate the biochemical and physiological mechanism of ciliary beating. Thus far, we investigated whether the spontaneous and stimulated states of cilia beating are controlled by the same intracellular molecular mechanisms. It was found that: (a) MgATP was sufficient to support spontaneous beating. (b) Ca2+ alone or Ca2+-calmodulin at concentrations as high as 1 μM could not alter ciliary beating. (c) In the absence of Ca2+, cyclic nucleotides produced a moderate rise in ciliary beating while in the presence of Ca2+ robust enhancement was observed. These results suggest that the axonemal machinery can function in at least two different modes.

Résumé :

Periodic excitation is a relatively simple and common active control mode. Owing to the advantages of direct access to environmental energy and controllability under periodic illumination, it enjoys broad prospects for application in soft robotics and opto-mechanical energy conversion systems. More new oscillating systems need to be excavated to meet the various application requirements. A spherical liquid crystal elastomer (LCE) balloon model driven by periodic illumination is proposed and its periodic beating is studied theoretically. Based on the existing dynamic LCE model and the ideal gas model, the governing equation of motion for the LCE balloon is established. The numerical calculations show that periodic illumination can cause periodic beating of the LCE balloon, and the beating period of the LCE balloon depends on the illumination period. For the maximum steady-state amplitude of the beating, there exists an optimum illumination period and illumination time rate. The optimal illumination period is proved to be equivalent to the natural period of balloon oscillation. The effect of system parameters on beating amplitude are also studied. The amplitude is mainly affected by light intensity, contraction coefficient, amount of gaseous substance, volume of LCE balloon, mass density, external pressure, and damping coefficient, but not the initial velocity. It is expected that the beating LCE balloon will be suitable for the design of light-powered machines including engines, prosthetic blood pumps, aircraft, and swimmers.

Résumé :

Photo-switchable chromophores are fluorescent inorganic dyes or proteins characterized by the tunability of their emission depending on the properties of the exciting radiation such as wavelength or intensity. The opportunities o ered by this kind of markers in the field of fluorescence microscopy, range from super-resolution imaging to molecular intracellular sensing of pH, calcium or second messengers. In this thesis I have studied the properties of two photo switchable GFP Mut2 mutants (E222Q and Mut2GQ) and their possible applications to biological fluorescence pump and probe imaging. From a strictly biological point of view the choice of a biological marker such as GFPs is very convenient since the uorescent label can be engineered to be naturally expressed by the cell under study. The risk of compromising or altering the cell cycle is reduced and, at the same time, labeling a ect the parent as well the daughter cells. These two mutants o er the possibility to investigate the role of the proton network around the GFP chromophore (in the case of the E222Q mutant) and the external protonation (in the case of the Mut2GQ mutant) of the GFP chromophore on the photo-switching. From the physical point of view, GFP Mut2 mutants, when excited by a less energetic pump wavelength, are characterized by long-lived non-fluorescent states whose depopulation can be triggered by irradiation with a more energetic probe beam. The first effect of the photo-induced depopulation of the long-lived state is the enhancement of the fluorescence signal due to the fact that the molecules are no more prevented to be excited to the high quantum yield singlet excited state. I have been able not only to characterize the fluorescence enhancement ratio of the GFP-Mut2 mutants, but also the characteristics relaxation times of the population and depopulation processes of the dark state. These parameters have a dependence on physical properties of their surroundings such as pH and viscosity, that could be exploited in imaging and sensing applications. Basing on this characterization I reasoned that the fluorescence enhancement (called in the thesis Enhancement Ratio) and the related relaxation time (Photoswitching Time) characteristic of these GFP mutants and other photoswitchable proteins, could be the basis for a new functional imaging technique. With this new protocol for image acquisition (called Beating Mode) it is possible to acquire images in which the contrast agent is not only the fluorescence intensity, but also the Enhancement Ratio or the Photoswitching Times. This imaging protocol can be easily extended to other photo-switchable proteins and by further characterizing their photo-switching properties as a function of pH or viscosity, it will offer the possibility to map biological functions in the samples. Here I outline and test the algorithms to perform what I called Intensity Modulation Beating Mode Imaging. However it must be noted that in order to reach the ultimate application of this technique, namely to perform intra-cellular sensing experiments via the detection of the photoswithcing parameters, the GFP mutants should be further engineered to allow cell transfection or membrane adhesion. This molecular biology step goes beyond the aim of my thesis. In this work, after the first introductory theoretical Chapters, I present a theoretical introduction to photo switchable GFP mutants in terms of physical and conformational properties (Chapter 3). In Chapter 4 we present the characterization of the behavior of the photo switching properties of the two mutants under study as a function of physical characteristics of the surroundings such as pH and viscosity. In the same Chapter we also present a joined theoretical-simulative model in order to analyze, in terms of FCS analysis, the coupling of the uorescence properties with the long lived dark state conformational dynamics. In Chapter 5, we describe the new image acquisition protocol developed in this work and called Beating Mode, both in terms of its potentialities and limitations, with a particular interest in the rationalization of the best operative condition and the applicability to biological sample. In Chapter 6 the applications of the Beating Mode protocol are finally outlined.

Résumé :

This thesis describes the use of counterpropagating pulse trains to quasi-phase-match high-harmonic generation (HHG). Two novel techniques for generating trains of ultrafast pulses are described and demonstrated. The first method makes use of a birefringent crystal array to split a single pulse into a sequence of pulses. The second method makes use of the time-varying polarisation of a chirped pulse passed through a multiple-order wave plate to generate a train of pulses by the addition of a polariser. It is demonstrated that this second technique can be used to make pulse trains with non-uniform pulse separation by using an acousto-optic programmable dispersive filter to manipulate the higher-order dispersion encountered by the chirped pulse. The crystal array method is used to demonstrate quasi-phase-matching of HHG in a gas-filled capillary, using one and two counterpropagating pulses. Enhancements of up to 60% of the intensity of the 27th harmonic of the 800,nm driving laser light are observed. Information on the spatial and dynamic properties of the HHG process is obtained from measurements of the coherence length in the capillary. Simulations of HHG in a capillary waveguide have been performed. These agree well with the results of the quasi-phase-matching experiments. The effect of mode-beating on the generation process in a capillary and its use as a quasi-phase-matching mechanism are investigated.

Résumé :

Previous research has confirmed the existence of a value premium in a wide array of markets and using this value stock anomaly has yielded superior performance. This thesis investigates if one could take advantage of the existence of a value premium to deploy a dynamic investment strategy on the Swedish stock market (OMXS30) with focus on minimizing risk to achieve higher risk adjusted performance than the stock market index. The investment strategy implemented use Market-to-Book-Value to screen for both entry and exit signals and Modern Portfolio Theory, using the minimum-variance portfolio with short-selling constraints, to allocate assets within the portfolio. The investment strategy is evaluated using the Modigliani-Modigliani Risk Adjusted Performance measure. Conclusions from the thesis are that the strategy does outperform the Swedish stock market index, both in terms of nominal return and risk-adjusted performance. The suboptimal behaviour of investors where they overreact to signals and unconsciously rely on heuristics is used to explain why this is possible. Market-to-Book-Value, using the first quartile as entry signal and third quartile as exit signal, is considered to be a successful key ratio to screen for value stocks.

Résumé :

Mechanical ventilation can be a life saving treatment. However, due to the inhomogeneous and anisotropic behavior of the lung tissue, ventilation can also lead to overdistensions of lung regions whereas other areas remain even collapsed. A first step is a more comprehensive understanding of the flow mechanics under normal breathing conditions in a healthy lung as well as for a diseased, collapsed lung. This is the aim of this work. Therefore, a realistic model of the upper human airways has been generated at which experimental and numerical investigations could be carried out. Experimentally, the flow was analyzed by means of Particle Image Velocimetry (PIV) measurements which revealed new details about the flow patterns occurring during different ventilation frequencies. Numerical results were in good agreement with the experimental results and could provide new details about the three-dimensional flow structure and emerging secondary flow within the upper airways. The study of reopening of collapsed airways has shown that larger frequencies lead to airway reopening without overdistension of already open parts. Higher frequencies also lead to homogenization of mass flow distribution within the human lung Künstliche Beatmung ist meist eine lebensrettende Maßnahme. Aufgrund der räumlich anisotropen und inhomogenen Eigenschaften der Lunge kann die Beatmung jedoch auch zu einer Schädigung der Lunge führen. Daraus ergibt sich die Forderung einer „Protektiven Beatmung“. Ein erster Schritt dahingehend ist ein verbessertes Verständnis der Atmung und Beatmung am Beispiel der gesunden sowie kranken, teilweise kollabierten Lunge. Dies ist das Ziel der Arbeit. Hierfür wurde ein realistisches Modell der oberen Atemwege (Tracheobronchialbaum) angefertigt. An diesem Modell können sowohl experimentelle als auch numerische Untersuchungen durchgeführt werden. Experimentell wurde die Strömung mittels Particle Image Velocimetry (PIV) untersucht, wobei neue Details bezüglich der auftretenden Strömungsmuster für unterschiedliche Frequenzen gefunden wurden. Numerische Strömungsberechnungen stimmen gut mit den experimentellen Ergebnissen überein. Dreidimensionale Strömungsstrukturen sowie die Entwicklung von Sekundärwirbeln in der Lunge konnten erklärt werden. Eine Studie am kranken, teilweise kollabierten Lungenmodell zeigte, dass mit steigender Frequenz kollabierte Bereiche wiedereröffnet werden können. Höhere Frequenzen führen weiterhin zu einer Homogenisierung der Massenstromverteilung in der Lunge

Texte intégral

Résumé :

In experimental acute respiratory distress syndrome (ARDS), random variation of tidal volumes (VT ) during volume controlled ventilation improves gas exchange and respiratory system mechanics (so-called stochastic resonance hypothesis). It is unknown whether those positive effects may be further enhanced by periodic VT fluctuation at distinct frequencies, also known as deterministic frequency resonance.We hypothesized that the positive effects of variable ventilation on lung functionmay be further amplified by periodic VT fluctuation at specific frequencies. In anesthetized and mechanically ventilated pigs, severe ARDS was induced by saline lung lavage and injurious VT (double-hit model). Animals were then randomly assigned to 6 h of protective ventilation with one of four VT patterns: (1) random variation of VT (WN); (2) P04, main VT frequency of 0.13Hz; (3) P10, main VT frequency of 0.05Hz; (4) VCV, conventional non-variable volume controlled ventilation. In groups with variable VT , the coefficient of variation was identical (30%). We assessed lung mechanics and gas exchange, and determined lung histology and inflammation. Compared to VCV, WN, P04, and P10 resulted in lower respiratory system elastance (63 ± 13 cm H2O/L vs. 50 ± 14 cm H2O/L, 48.4 ± 21 cm H2O/L, and 45.1 ± 5.9 cm H2O/L respectively, P < 0.05 all), but only P10 improved PaO2/FIO2 after 6 h of ventilation (318 ± 96 vs. 445 ± 110mm Hg, P < 0.05). Cycle-by-cycle analysis of lung mechanics suggested intertidal recruitment/de-recruitment in P10. Lung histologic damage and inflammation did not differ among groups. In this experimental model of severe ARDS, periodic VT fluctuation at a frequency of 0.05Hz improved oxygenation during variable ventilation, suggesting that deterministic resonance adds further benefit to variable ventilation.

Résumé :

碩士 國立聯合大學 光電工程學系碩士班 100 In this work, we demonstrated high-sensitivity broadband asymmetric fiber Michelson interferometer with a spatial mode beating arm where its output end has a sphered-end hollow-core fiber as a sensing head. The multiple foci can offer the advantage for direction determination. The total length of sensor head is less than 300μm and displacement resolution is about 0.8nm. The hollow core is slightly smaller than the solid core of a single-mode fiber, so the fractional power of the core mode is converted into cladding modes. The excited cladding modes propagate at distinct optical paths along the hollow-core fiber and have individual foci outside the spherical lens. The reflected core mode, generated at the solid core–air interface, and the reflected cladding modes, generated at external material, interfere with each other to produce beating in the interference signals. The spatial mode beating not only can be useful in displacement measurement but also determine the moving direction immediately with high sensitivity. A micro-FMI featuring a compact structure is definitely advantageous to provide stable and accurate measurements for harsh environments with high mechanical vibration or temperature instability.

Résumé :

Chaotic regimes have been observed experimentally in neurons as well as in deterministic neuronal models. The bursting R15 cell in the abdominal ganglion of Aplysia has been the subject of extensive mathematical modeling. The model of Plant and Kim is capable of exhibiting both bursting and beating modes of electrical activity. We demonstrate (1) that a chaotic regime exists between the bursting and beating modes of the model, and (2) that the model approaches chaos from both modes by a period doubling cascade. We propose an original model of R15 which differs from previous models in several ways: the inclusion of a calcium ion balance, the underlying assumption that the calcium-dependent inactivation of a calcium current rather than the calcium-dependent activation of a potassium current mediates bursting activity, and the incorporation of experimental data to the extent possible. Preliminary results support the contention that a chaotic regime is intermediate between the beating and bursting modes. (Abstract shortened with permission of author.)

Résumé :

This chapter explores the long-term effects of internal displacement caused by the Kurdish-Turkish conflict on women’s attitudes towards domestic violence. Using the Turkish Demographic and Health Survey, we show that Kurdish women who migrated from their homes during the conflict are more likely to believe that a husband is justified in beating his wife; and the spouses of migrant women were more likely to have tried to control their wives by limiting their movements or social interactions. In a novel dataset of applicants to a women’s shelter, we find that forced migrant women have endured violence for longer and of greater intensity before deciding to seek assistance. We discuss possible mechanisms through which forced migration may affect migrants’ attitudes towards domestic violence.

Résumé :

Organ transplantation is the standard treatment modality for end-stage organ disease in selected cases. Two types of potential organ donors can be identified: the brain-dead ‘heart-beating donors’, referred to as DBD (donation after brain death), and the warm ischaemic ‘non-heart-beating donors’, referred to as DCD (donation after circulatory death). Brain death induces several physiological changes in the DBD donor. An autonomic storm is characterized by massive catecholamine release, followed by autonomic depletion during a vasoplegic phase. This is associated with several hormonal changes (suppression of vasopressin, the hypothalamic-pituitary-adrenal axis, and the hypothalamic-pituitary-thyroid axis) and an inflammatory response. These physiological changes form the basis of organ donor management, including cardiovascular stabilization and hormonal therapy (including vasopressin and analogues, thyroid hormone, and cortisol). Donor management is the continuation of critical care, with a shift towards individual organ stabilization. An aggressive approach to maximize organ yield is recommended; however, many treatment strategies need further investigation in large randomized trials. DCD donors have now evolved as a valid alternative to increase the potential donor pool and challenge the clinician with new questions. Optimal donor comfort therapy and end-of-life care are important to minimize the agonal phase. A strict approach towards the determination of death, based on cardiorespiratory criteria, is prerequisite. Novel strategies have been developed, using ex situ organ perfusion as a tool, to evaluate and recondition donor organs. They might become more important in the future to further optimize organ quality.

Résumé :

This chapter considers the provision of context and analysis in television news. Americans have tended to be realist, viewing problems as “concrete rather than abstract” and are relying more on television for news, which simplifies “complex issues to the level of anecdotal evidence.” However, episodic newscasts may lead audiences to ignore the modern big picture of social conditions and public policy behind problems. For a century the U.S. population has scored poorly on standard memory tests of political knowledge. An uninformed audience may need more explanations, but did the interpretive turn fail to spread to television as critics suggest? It is shown that television news adopted the wider modern perspectives that critics demanded. Since the 1960s, newscasters have expanded interpretation on national evening news. After beating newspapers to the newest stories, network newscasts themselves began shifting into modern interpretive styles instead of sticking with realist, episodic coverage.

Résumé :

Movements to end violence against women in the United States have brought the issues of rape, incest, wife-beating, and sexual harassment to public attention, given birth to community support systems for survivors, laid the foundation for research, and triggered significant cultural change. However, they have not been without their critics. After tracing the history of the battered women’s and the anti-rape movements, this chapter explores three areas of controversy surrounding both movements. The first is the charge that activists have abandoned their feminist political agendas and have become part of the social service mainstream. The second criticism is that the movements have excluded minority women and, as a result, have supported policies that do more harm than good. The third debate surrounds whether these movements have been co-opted by the state and are used more to regulate and control the poor and minorities than to challenge existing structures of power.

Résumé :

Financial concerns were a factor in McGlynn’s decision to contact Cruise in late March 1856. So too was a fear that he would be connected to a letter threatening Gallagher which he had written at the behest of the Mollies. That anxiety, in turn, stemmed from the fractious politics of the local lodge. The previous year, its ‘master’ had survived a challenge from militants who thought that he should be ordering more ‘outrages’. However, the militants remained a strong faction in the lodge. McGlynn’s fear heightened when the savage beating of a man in a neighbouring parish caused the Catholic clergy to condemn the Mollies. McGlynn’s information revealed Gallagher’s neglect of his aged father, John, to have been an additional source of the Mollies’ animosity to him; so too, it seems, was the death of a man struck with a whip by a relative of his wife.

Résumé :

This chapter examines television news' reporting of the Selma campaign for voting rights that led directly to the passage of the 1965 Voting Rights Act. Television cameras present on the Edmund Pettus Bridge on Sunday March 7, 1965, were able to capture the beating, gassing, and brutalizing suffered by voting rights demonstrators as they attempted to march to Montgomery. The uproar generated by that footage generated more support, volunteers, and moral clout for the civil rights movement. This chapter considers how one news program, The CBS Evening News with Walter Cronkite, presented the Selma campaign as an ongoing nightly news story, with particular emphasis on its coverage of the campaign's three martyrs: Jimmie Lee Jackson, Rev. James Reeb, and Viola Liuzzo. It also discusses the response of white Selmians in the “glaring light of television” and the commentary in the African American press regarding the television coverage of the campaign.

Résumé :

Abstract Video games have captivated us for over 50 years, giving us entire worlds to explore, new ways to connect with friends, thought-provoking stories, or just a fun way to pass the time. Creating games is a dream for many, but making great games is challenging. This is a book about that challenge. More specifically, it’s a book about game interaction design—in other words, shaping what players can do and how they do it to make a game satisfying and memorable. Our time with a game is built on interaction, from basic things like pushing buttons on a controller, to making complicated strategic decisions and engaging with its narrative. If you’ve ever felt the adrenaline rush from beating a perfectly tuned boss fight or been delighted by the fanfare of picking up that last collectible, you’ve experienced good interaction design first-hand. This book is about learning what makes for great (or terrible!) interaction design in games, exploring things like controls, feedback, story, and tutorial design by analyzing existing games. It also looks at how newer and still-developing tech like VR and streaming are changing the ways we play, and how you can bring great interaction design to your own games.

Résumé :

The Yvelines criminal court has recently acquitted Mr. Leber (see Le monde, January 24),1 who had fatally beaten his wife and who had left her to slowly die on the kitchen floor all night long.What we are calling into question are the sexist motivations that have led to this acquittal. For having broken a few windows, young people are sentenced to years of imprisonment. For having killed his wife, Mr. Leber will receive no penalty on the pretext that this offense falls under the domain of “love” or the conjugal relationship. It is worth questioning a judicial system where circumstances that are usually aggravating become, in this case, attenuating circumstances....

Résumé :

A twenty-three-year-old Algerian woman and liaison agent for the FLN was imprisoned, tortured, raped with a bottle by French military men, and it’s considered ordinary.1 Since 1954, in the name of suppressing rebellion, then of pacification, we are all accomplices of a genocide that has claimed over a million victims; men, women, old folks and children have been slaughtered: gunned down during search-raids, burned alive in their villages, throats slit or bellies ripped open, many tortured to death. Entire tribes have been left to starve and freeze, at the mercy of beatings and epidemics in the “relocation camps” which are in fact extermination camps—serving also as brothels to the elite soldiers—and where more than five hundred thousand Algerians currently await their death. During the course of the last few months, the press, including even the most circumspect papers, has been full of horror stories: assassinations, lynchings, violent racist attacks on Arab immigrants; manhunts in the streets of Oran; corpses by the dozen in Paris, hanging from trees in the Bois de Boulogne and along the banks of the Seine; maimed limbs and blown up heads; bloody All Saints Day in Algiers....

Résumé :

Of all political concepts of relatively recent times, fascism, along with the name of the Nazi chief, Adolf Hitler, elicits the most automatically negative reaction in most minds. Its mention at once conjures images of marching automatons, extreme violence, war, and genocide. The fascists, along with Hitler, it is widely assumed, were virtuously beaten in the Second World War, when liberals, democrats and socialists, capitalists and communists, came together, at least from 1941, to resist, to produce, to conquer, and to save humankind. Even though it is now more than sixty years since Hitler and his Italian ally, Benito Mussolini, died at the end of the Second World War, the history of fascism, it seems, retains contemporary menace.

Résumé :

This chapter explores the significance of the cinaedus in Roman literature, where he is portrayed as both a type of deviant in terms of his gender and sexual behavior as well as a kind of performer, who is noted for his use of percussive instruments, signature verse-meter (the Sotadean), and a dance involving a shimmying of the buttocks. It uses the metaphor of beating—as a form of punishment for sexual transgressions, as a means of corporal tenderization, and as a mode of sonic agency—to analyze the overlapping and sometimes contradictory valences associated with this figure in various Latin sources (Plautus, Catullus, Petronius, and Martial among others) from the third century BCE to the second century CE.

Résumé :

This chapter engages with the geopolitical context of the Gothic’s migration from the periphery to the fast-beating heart of popular culture – specifically the rise to economic and cultural predominance of global neoliberalism. I contend that the Gothic texts of the neoliberal age can be seen to undertake the same kind of cultural work that was carried out by the Gothic mode in earlier periods of socio-economic turbulence. And, as in earlier periods, we can see a variety of ideological allegiances at play in Gothic texts of the neoliberal age – ranging from the revolutionary to the radical to the downright reactionary. The chapter ranges across texts and media including novels – i.e. Justin Cronin’s The Passage (2010), Hemlock Grove (2013–15), The Strain (2012–17), True Blood (2008–14), World War Z (2006) and In the Flesh (2013–14).
