＜p＞"Avrei voluto scriverlo io." Cos? Stieg Larsson ha accolto questo libro, che non ? un romanzo ma un'inquietante storia vera: quella personale di un serial killer e insieme della Svezia contemporanea. Per un anno, nel 1991, John Ausonius, armato di un fucile a mirino laser, semina il panico a Stoccolma con attentati a cittadini di origine straniera, impegnando polizia e servizi segreti in una lotta contro il tempo nella pi? vasta caccia all'uomo dall'omicidio del premier Olof Palme. In un monumentale racconto-reportage che segue in presa diretta l'indagine dalla prospettiva dei protagonisti, Gellert Tamas ricostruisce un caso emblematico della deriva xenofoba nell'odierna societ? multiculturale cos? come il terreno fertile che lo ha prodotto: la grande crisi economica che ha cambiato volto al paese, l'ascesa lampo dell'estrema destra e dei movimenti neonazisti, la discriminazione razziale e l'escalation di violenza tollerate dalle autorit?. E rielaborando la mole di fonti, a partire da interviste esclusive, d? corpo, voce e anima a un personaggio straordinario, da studente modello a barbone, da yuppie rampante a rapinatore e assassino seriale. Un uomo solo, vittima e carnefice, incompreso e fanatico, goffo eppure pieno di risorse, che il caso, la malattia e il clima politico trasformano in un Forrest Gump del male.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞This thesis covers a diverse set of topics related to space-based gravitational wave detectors such as the Laser Interferometer Space Antenna (LISA). The core of the thesis is devoted to the preprocessing of the interferometric link data for a LISA constellation, specifically developing optimal Kalman filters to reduce arm length noise due to clock noise. The approach is to apply Kalman filters of increasing complexity to make optimal estimates of relevant quantities such as constellation arm length, relative clock drift, and Doppler frequencies based on the available measurement data. Depending on the complexity of the filter and the simulated data, these Kalman filter estimates can provide up to a few orders of magnitude improvement over simpler estimators. While the basic concept of the LISA measurement (Time Delay Interferometry) was worked out some time ago, this work brings a level of rigor to the processing of the constellation-level data products.＜/p＞ ＜p＞The thesis concludes with some topics related to the eLISA such as a new class of phenomenological waveforms for extreme mass-ratio inspiral sources (EMRIs, one of the main source for eLISA), an octahedral space-based GW detector that does not require drag-free test masses, and some efficient template-search algorithms for the case of relatively high SNR signals.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞This technical book considers the application side of LDA techniques. Starting from the basic theories that are crucial for each LDA user, the main subject of the book is focused on diverse application methods. In details, it deals with universal methodical techniques that have been mostly developed in the last 15 years. The book thus gives for the first time an application reference for LDA users in improving the optical conditions and enhancing the measurement accuracies. It also provides the guidelines for simplifying the measurements and correcting measurement errors as well as for clarifying the application limits and extending the application areas of LDA techniques. Beside the treatments of some traditional optical and flow mechanical features influencing the measurement accuracies, the book shows a broad spectrum of LDA application methods in the manner of measuring the flow turbulence, resolving the secondary flow structures, and quantifying the optical aberrations at measurements of internal flows etc.. Thus, it also supports the further developments of both the hard- and software of LDA instrumentations.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。

＜p＞together with the oncologist. For man, the laser must be moved out of the laboratory into the operating room. At present, its true position in the cancer therapy program is not yet known. The greatest attention is being directed to melanoma because of the tremendous energy adsorption capabilities of this heavily pigmented tumor. The next area of interest is in uncommon and com mon tumors of blood vessels. Here, too, the color factor influences to a signifi cant degree the absorption of the laser. Multiple accessible malignancies are treated also by the laser chiefly to compare the effect here with other modalities of therapy. Finally, as a type of therapy of desperation, lasers are used in the treatment of metastatic lesions. This then, is the brief introduction to the study of the current status of laser cancer research. Intense, difficult and cooperative research of the next few years will determine the role of the laser, an "optical knife", as an investi gative or therapeutic instrument.

＜p＞The interaction of high-power lasers with matter can generate Terahertz radiations that efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in medical and security applications. When a short intense laser pulse ionizes a gas, it may produce new frequencies even in VUV to XUV domain. The duration of XUV pulses can be confined down to the isolated attosecond pulse levels, required to study the electronic re-arrangement and ultrafast processes. Another important aspect of laser-matter interaction is the laser thermonuclear fusion control where accelerated particles also find an efficient use.＜/p＞ ＜p＞This book provides comprehensive coverage of the most essential topics, including＜/p＞ ＜ul＞ ＜li＞＜/li＞ ＜li＞Electromagnetic waves and lasers＜/li＞ ＜li＞＜/li＞ ＜li＞THz radiation using semiconducting materials / nanostructures / gases / plasmas＜/li＞ ＜li＞＜/li＞ ＜li＞Surface plasmon resonance＜/li＞ ＜li＞＜/li＞ ＜li＞THz radiation detection＜/li＞ ＜li＞＜/li＞ ＜li＞Particle acceleration technologies＜/li＞ ＜li＞＜/li＞ ＜li＞X-ray lasers＜/li＞ ＜li＞＜/li＞ ＜li＞High harmonics and attosecond lasers＜/li＞ ＜li＞＜/li＞ ＜li＞Laser based techniques of thermonuclear fusion＜/li＞ ＜li＞＜/li＞ ＜li＞Controlled fusion devices including NIF and ITER＜/li＞ ＜/ul＞ ＜p＞The book comprises of 11 chapters and every chapter starts with a lucid introduction to the main topic.
