description: Since the discovery of adiabatic quantum computing, a need has arisen for rigorously proven bounds for the error in the adiabatic approximation. We present in this paper, a rigorous and elementary derivation of upper and lower bounds on the error incurred from using the adiabatic approximation for quantum systems. Our bounds are often asymptotically tight in the limit of slow evolution for fixed Hamiltonians, and are used to provide sufficient conditions for the application of the adiabatic approximation. We show that our sufficiency criteria exclude the Marzlin--Sanders counterexample from the class of Hamiltonians that obey the adiabatic approximation. Finally, we demonstrate the existence of classes of Hamiltonians that resemble the Marzlin--Sanders counterexample Hamiltonian, but also obey the adiabatic approximation.
VHE Gamma-Ray Induced Pair Cascades in the Radiation Fields of Dust Tori of AGN: Application to Cen A

description: The growing number of extragalactic high-energy (HE, E > 100 MeV) and very-high-energy (VHE, E > 100 GeV) gamma-ray sources that do not belong to the blazar class suggests that VHE gamma-ray production may be a common property of most radio-loud Active Galactic Nuclei (AGN). In a previous paper, we have investigated the signatures of Compton-supported pair cascades initiated by VHE gamma-ray absorption in monochromatic radiation fields, dominated by Ly-alpha line emission from the Broad Line Region. In this paper, we investigate the interaction of nuclear VHE gamma-rays with the thermal infrared radiation field from a circumnuclear dust torus. Our code follows the spatial development of the cascade in full 3-dimensional geometry. We provide a model fit to the broadband SED of the dust-rich, gamma-ray loud radio galaxy Cen A and show that typical blazar-like jet parameters may be used to model the broadband SED, if one allows for an additional cascade contribution to the Fermi gamma-ray emission.

description: We study the five-orbital Hubbard-Holstein model for iron pnictides with small electron-phonon interaction due to Fe-ion Einstein oscillators. Using the fluctuation-exchange (FLEX) approximation, orbital fluctuations evolve inversely proportional to the temperature, and therefore the resistivity shows linear or convex T-dependence for wide range of temperatures. We also analyze the Eliashberg gap equation, and show that s-wave superconducting state without sign reversal (s_{++}-wave state) emerges when the orbital fluctuations dominate the spin fluctuations. When both fluctuations are comparable, their competition gives rise to a nodal s-wave state. The present study offers us a unified explanation for both the normal and superconducting states.

description: Long Term Evolution has been standardized by the 3GPP consortium since 2008, with 3GPP Release 12 being the latest iteration of LTE Advanced, which was finalized in March 2015. High Efficiency Video Coding has been standardized by the Moving Picture Experts Group since 2012 and is the video compression technology targeted to deliver High-Definition video content to users. With video traffic projected to represent the lion's share of mobile data traffic in the next few years, providing video and non-video users with high Quality of Experience is key to designing 4G systems and future 5G systems. In this thesis, we present a cross-layer scheduling framework which delivers video content to video users by exploiting encoding features used by the High Efficiency Video Coding standard such as coding structures and motion compensated prediction. We determine which frames are referenced the most within the coded video bitstream to determine which frames have higher utility for the High Efficiency Video Coding decoder located at the user's device and evaluate the performances of best effort and video users in 4G networks using finite buffer traffic models. We look into throughput performance for best effort users and packet loss performance for video users to assess Quality of Experience. Our results demonstrate that there is significant potential to improve the Quality of Experience of best effort and video users using our proposed Frame Reference Aware Proportional Fair scheme compared to the baseline Proportional Fair scheme.

description: Die Dissertation "A Grammar of Vamale, a language of New Caledonia" ist eine Gesamtbeschreibung einer südozeanischen Sprache, die von ca. 180 Menschen in Nordost-Neukaledonien gesprochen wird. Einerseits ist die Sprache typisch für die Gegend, andererseits ein interessantes Resultat von Mehrsprachigkeit, Diaspora und Nachbarschaft mit unterschiedlichen Sprachgruppen: komplexer gewordene Alinierungssysteme, ein historisch durch Kontakt gewachsenes Phoneminventar, und ein reiches Aspektsystem zeichnen Vamale aus. In 11 Monaten Feldforschung sind viele Texte zusammengekommen von denen viele Beispiele entnommen sind und drei komplett im Anhang wiedergegeben; die Grammatik vergleicht ausserdem die Sprachstrukturen mit dem Proto-Ozeanischen, verwandten Dialekten und Nachbarsprachen. Die Gliederung der Arbeit folgt einem klassischen Muster: Soziolinguistisches, Phonologie, Wortklassen, dann Verben und Nomen mit ihren Phrasen, und schliesslich einfache und komplexe Sätze.

description: Circumstellar disks surrounding young stars are known to be the birthplaces of planets, and the innermost astronomical unit is of particular interest. We present new long-baseline spectro-interferometric observations of the HerbigAe star, HR5999, obtained in the H and K bands with the AMBER instrument at the VLTI, and aim to produce near-infrared images at the sub-AU spatial scale. We spatially resolve the circumstellar material and reconstruct images using the MiRA algorithm. In addition, we interpret the interferometric observations using models that assume that the near-infrared excess is dominated by the emission of a circumstellar disk. We compare the images reconstructed from the VLTI measurements to images obtained using simulated model data. The K-band image reveals three main elements: a ring-like feature located at ~0.65 AU, a low surface brightness region inside, and a central spot. At the maximum angular resolution of our observations (1.3 mas), the ring is resolved while the central spot is only marginally resolved, preventing us from revealing the exact morphology of the circumstellar environment. We suggest that the ring traces silicate condensation, i.e., an opacity change, in a circumstellar disk around HR 5999. We build a model that includes a ring at the silicate sublimation radius and an inner disk of low surface brightness responsible for a large amount of the near-infrared continuum emission. The model successfully fits the SED, visibilities, and closure phases, and provides evidence of a low surface brightness region inside the silicate sublimation radius. This study provides additional evidence that in HerbigAe stars, there is material in a low surface brightness region, probably a low optical depth region, located inside the silicate sublimation radius and of unknown nature.

description: Der Umgang mit Fremdwährungsrisiken stellt aufgrund der starken internationalen Verflechtung für viele Schweizer Unternehmen ein zentrales Thema dar, gerade auch aufgrund der Aufhebung der Kursuntergrenze des Schweizer Franken gegenüber dem Euro am 15. Januar 2015. Die vorliegende Studie knüpft an eine im Jahr 2014 publizierte Beschreibung von 13 Unternehmen an. Die vorliegende Studie widmet sich den Fragen ob, inwiefern und weshalb sich die Verhaltensweisen zur Steuerung der Währungsrisiken seit dem Jahr 2014 veränderten. Die nachfolgenden Aussagen basieren hauptsächlich auf 13 im vierten Quartal 2015 geführten Interviews. Aus der Analyse geht hervor, dass fünf Unternehmen ihre Risikomanagementstrategie anpassten, was jedoch nicht nur mit den Ereignissen am 15. Januar 2015 begründet werden kann. Der Risikomanagementprozess wurde hingegen von deutlich mehr Unternehmen angepasst. Neben Bestrebungen hin zu einem besseren «Natural Hedging» fanden auch mehrfach Einführungen von Treasury Management Systemen (TMS) sowie elektronischen Devisenhandelsplattformen statt. Mehrere Unternehmen haben Bestrebungen zur Etablierung rollierender Forecasts sowie automatisierter Erkennung von Währungsrisiken unternommen. Die Aufhebung der Kursuntergrenze des Schweizer Franken gegenüber dem Euro am 15. Januar 2015 hat insbesondere zu drei Reaktionen geführt: Erstens haben Unternehmen (teilweise rigorose) Kostensenkungsprogramme initiiert und umgesetzt, zweitens (teilweise einschneidende) Preisveränderungen vorgenommen und drittens Einkaufsaktivitäten in die Eurozone verschoben. Allerdings hat die Aufhebung der Kursuntergrenze gegenüber dem Euro die grundsätzlichen strategischen Absicherungsentscheide kaum beeinflusst.

This new species is closely allied to P. chrysopus, Selys, both in the general wing-structure and the colour-pattern of the abdomen, as in regard to the structure of the anal appendages of the male. It differs very strikingly in the colour of the legs and in details of the thoracic colour-pattern, which, in chrysopus, are very constant characters (fig. 4 a). I have much pleasure in naming this species after Dr. P. Buwalda, who as a botanist took great interest in collecting insects as well.

The will to overcome : experiments in mud running, modernism and more than human kinetics
Creators: name: Weedon, Gavin
Publisher: name: University of British Columbia
Year: 2016

description: Mud running is an expression of physical culture that champions the naturality of functional fitness, the primacy and playfulness of ‘premodern’ life, labour and leisure, and the capacity of all-comers to overcome mud-laden obstacle courses. The ambition of this dissertation is to bring posthumanist theory into contact with mud running and its humanistic ethic of ‘overcoming obstacles,’ and in doing so to extend knowledge of the prevailing history, theoretical premises and embodied experiences of physical culture. Emerging from an array of research practices, from fieldwork to textual analyses, each of my studies critically addresses the understandings of nature, body, self and society that prevail in mud running. In the first study, I pursue the ontological inheritance that makes it possible to invoke humankind as being outside of nature; at a critical distance from mud, dirt, and soil. This genealogical approach suggests mud running to be a recuperation of nineteenth century forms of physical culture which also encouraged getting somehow ‘back-to-nature,’ as well as identifying mud running and physical culture as expressions of their modernist, colonial heritage. The second study recasts the ‘camaraderie’ for which mud running is renowned as an outcome of material, corporeal and symbolic enactments in which a whole host of actors, human and otherwise, make dramatic and subtle contributions. Contra the modernist notion of humans overcoming natural or technological obstacles, this analysis recasts the conventional hero figure, the super-human athlete, to afford due attention to the often unsung ensemble of intra- and supra-human materialities with which these athletes share an ecology. The third study draws from affect theory to evoke mud running as a sensoria in which runners are not simply overcoming obstacles, but are themselves overcome by affective registers and responses. I describe how atavistic nostalgia, military-hero mimesis, as well as compassion and inspiration emerge from encounters with obstacle courses. At stake in these studies are not only questions surrounding the remarkable rise of events such as Tough Mudder and Spartan Race in recent years or their physical cultural heritage, but their shared claims as to what it means, and what it takes to be human.

description: There are discernible and fundamental differences between clocks, waves and physical states in classical physics. These fundamental concepts find a common expression in the context of quantum physics in gravitational fields; matter and light waves, quantum states and oscillator clocks become quantum synonymous through the Planck-Einstein-de Broglie relations and the equivalence principle. With this insight, gravitational effects on quantum systems can be simply and accurately analyzed. Apart from providing a transparent framework for conceptual and quantitative thinking on matter waves and quantum states in a gravitational field, we address and resolve with clarity the recent controversial discussions on the important issue of the relation and the crucial difference between gravimetery using atom interferometers and the measurement of gravitational time dilation.

title: Genetic analysis of female fertility focussing on multiple birth events in Swiss cattle

Subjects: subject: 590 Animals (Zoology)

description: In dairy cattle farming, intensive selection for milk yield has led to a decline in female fertility in the last decades, due to unfavourable genetic correlations between milk yield and female fertility. Phenotypes included in current genetic evaluations of fertility are interval and binary traits, calculated from insemination and previous calving date records and deduced from insemination success, respectively. For improved selection, the development of novel phenotypes that describe the physiology of reproduction more precisely would be beneficial. A potential novel phenotype is multiple births. Especially in dairy cattle, multiple birth events are undesirable due to negative impacts on a cow’s performance and potential health issues of the dam and the calves.
In the first part of the thesis, I investigated the genetic background of multiple birth events in population studies for the four main Swiss dairy cattle breeds. For this purpose, I designed a breeding value estimation for this novel phenotype in Switzerland. By applying genome-wide association studies (GWAS) on the estimated breeding values, quantitative trait loci (QTL) for multiple births were detected in the three different Swiss dairy cattle populations Holstein, Brown Swiss and Original Braunvieh on chromosomes 11, 15 and 11, respectively. In all populations I identified candidate causal variants affecting the expression of the genes LHCGR, FSHR, ID2, PRDM11 and SYT13 by using linkage disequilibrium analysis for fine-mapping.
In the second part of the thesis, I tested alternative methods to identify associated genomic regions, which do not require a complex pipeline of specialised software-tools and massive computing resources. Preliminary work for using machine learning tools in the analysis of binary traits was provided. Thereby, I used the Least Absolute Shrinkage and Selection Operator (Lasso), support vector machine and random forest algorithms for identifying QTL in a case/control approach. The machine learning approaches were validated as promising and efficient alternatives to classical methods. Their application led to the identification of genomic regions showing suggestive associations for multiple births in Holstein cattle.
In future, the machine learning tools random forest, Lasso and support vector machine can offer a low input alternative for GWASs while the availability of data for traits of interest are increasing. The identification of QTL for multiple births improves the understanding of the genetic architecture that underlies our trait of interest and female fertility in general. By developing the breeding value prediction, we set the foundation for implementing our knowledge in the breeding strategies to avoid multiple births in future. Considering this novel phenotype of female fertility will improve the sustainability of dairy cattle farming.
The embodied and emotive role of the art gallery educator

Publisher: name: University of British Columbia
Year: 2016

description: This self-study outlines the uncertainties and insecurities that art gallery and museum educators face as our roles are defined by shifting policies and mandates in education as well as within the museum. I collaborated with a classroom teacher who observed a tour I gave her grade three class. After an in depth dialogue and ongoing correspondence reflecting upon ways of engaging students, I led her class through another exhibition to see if our collaboration and dialogue shifted my thinking and practice as an art gallery educator. As I searched for a way to articulate my role, I found the roles of collaborator, audience evaluator, and emotive catalyst to be just as valuable as engaging school groups in verbal dialogue in the gallery. The dialogue that was transformative for my thinking was the one outside of the gallery with the teacher. This self-study tells the story of the shifts in my thinking and practice. I learned to hold back information rather than focus on verbal dialogue to allow students to have their own ‘emotive embodied experience’ of learning in the gallery.

description: The main atmospheric parameters and abundances of the iron group elements (vanadium, chromium, iron, cobalt and nickel) are determined for 62 red giant "clump" stars revealed in the Galactic field by the Hipparcos orbiting observatory. The stars form a homogeneous sample with the mean value of temperature T=4750 +- 160K, of surface gravity log g = 2.41 +- 0.26 and the mean value of metallicity [Fe/H] = -0.04 +- 0.15 dex. A Gaussian fit to the [Fe/H] distribution produces the mean [Fe/H] = -0.01 dex and dispersion of [Fe/H] = 0.08 dex. The near-solar metallicity and small dispersion of [Fe/H] of clump stars of the Galaxy obtained in this work confirm the theoretical model of the Hipparcos clump by Girardi & Salaris (2001). This suggests that nearby clump stars are (in the mean) relatively young objects, reflecting mainly the near-solar metallicities developed in the local disk during the last few Gyrs of its history. We find iron group element to iron abundance ratios in clump giants to be close to solar.

description: The mystery of the normal state in the underdoped cuprates has deepened with the use of newer and complementary experimental probes. While photoemission studies have revealed solely `Fermi arcs' centered on nodal points in the Brillouin zone at which holes aggregate upon doping, more recent quantum oscillation experiments have been interpreted in terms of an ambipolar Fermi surface, that includes sections containing electron carriers located at the antinodal region. To address the question of whether an ambipolar Fermi surface truly exists, here we utilize measurements of the second harmonic quantum oscillations, which reveal that the amplitude of these oscillations arises mainly from oscillations in the chemical potential, providing crucial information on the nature of the Fermi surface in underdoped YBa2Cu3O6+x. In particular, the detailed relationship between the second harmonic amplitude and the fundamental amplitude of the quantum oscillations leads us to the conclusion that there exists only a single underlying quasi-two dimensional Fermi surface pocket giving rise to the multiple frequency components observed via the effects of warping, bilayer splitting and magnetic breakdown. A range of studies suggest that the pocket is most likely associated with states near the nodal region of the Brillouin zone of underdoped YBa2Cu3O6+x at high magnetic fields.

description: The aim of this work is to review the tunnelling method as an alternative description of the quantum radiation from black holes and cosmological horizons. The method is first formulated and discussed for the case of stationary black holes, then a foundation is provided in terms of analytic continuation throughout complex space-time. The two principal implementations of the tunnelling approach, which are the null geodesic method and the Hamilton-Jacobi method, are shown to be equivalent in the stationary case. The Hamilton-Jacobi method is then extended to cover spherically symmetric dynamical black holes, cosmological horizons and naked singularities. Prospects and achievements are discussed in the conclusions.

description: We investigate the non-Gaussian features of the IGM at redshift $z\sim 5 - 6$ using Ly$α$ transmitted flux of quasar absorption spectra and cosmological hydrodynamic simulation of the concordance $Λ$CDM universe. We show that the neutral hydrogen mass density field and Ly$α$ transmitted flux fluctuations possess all the non-Gaussian features predicted by the log-Poisson hierarchy, which depends only on two dimensionless parameters $β$ and $γ$, describing, respectively, the intermittence and singularity of the random fields. We find that the non-Gaussianity of the Ly$α$ transmitted flux of quasars from $z=4.9$ to $z=6.3$ can be well reconstructed by the hydrodynamical simulation samples. Although the Gunn-Peterson optical depth and its variance underwent a significant evolution in the redshift range of $5 - 6$, the intermittency measured by $β$ is almost redshift-independent in this range. More interesting, the intermittency of quasar's absorption spectra on physical scales $0.1-1$ h$^{-1}$Mpc in redshift $5 - 6$ are found to be about the same as that on physical scales $1-10$ h$^{-1}$Mpc at redshifts $2 - 4$. Considering the Jeans length is less than 0.1 h$^{-1}$Mpc at $z\sim 5$, and $1$ h$^{-1}$Mpc at $z\sim 2$, these results imply that the nonlinear evolution in high and low redshifts will lead the cosmic baryon fluid to a state similar to fully developed turbulence. The log-Poisson high order behavior of current high redshift data of quasar's spectrum can be explained by uniform UV background in the redshift range considered. We also studied the log-Poisson non-Gaussianity by considering inhomogeneous background. With several simplified models of inhomogeneous background, we found the effect of the inhomogeneous background on the log-Poisson non-Gaussianity is not larger than 1-sigma.

description: Excerpt: Let us examine the need for improved rural housing. In all areas within the nation some farm families are inadequately housed. In many areas the need for better housing is acute among a large percentages of the farm population. While the existence of rural slums is recognized, many do not realize that more than one fourth of the farm people are housed under what might well be called slum conditions; conditions which are breeding serious weaknesses which we must guard against - ill health, epidemics, delinquency, discontent, and hopelessness. These are conditions which can be corrected in part by improvements in rural housing. A realistic approach to the solution of the housing problem requires action to provide for at least the minimum requirements essential for healthful and respectable living, and for attaining standards consistent with American ideals.

description: Near infrared pump-probe spectroscopy has been used to measure the ultrafast dynamics of photoexcited charge carriers in monolayer and multilayer graphene. We observe two decay processes occurring on 100 fs and 2 ps timescales. The first is attributed to the rapid electron-phonon thermalisation in the system. The second timescale is found to be due to the slow decay of hot phonons. Using a simple theoretical model we calculate the hot phonon decay rate and show that it is significantly faster in monolayer flakes than in multilayer ones. In contrast to recent claims, we show that this enhanced decay rate is not due to the coupling to substrate phonons, since we have also seen the same effect in suspended flakes. Possible intrinsic decay mechanisms that could cause such an effect are discussed.

description: A multiple wavevector (Q) reconstruction of the Fermi surface is shown to yield a profoundly different electronic structure to that characteristic of single wavevector reconstruction, despite their proximity in energy. We consider the specific case in which ordering is generated by Qx = [2πa, 0] and Qy = [0,2πb] (in which a = b = 1/4) - similar to those identified in neutron diffraction and scanning tunneling microscopy experiments, and more generally show that an isolated pocket adjacent to the nodal point knodal = [\pm π/2, \pm π/2] is a protected feature of such a multiple-Q model, potentially corresponding to the nodal 'Fermi arcs' observed in photoemission and the small size of the electronic heat capacity found in high magnetic fields - importantly, containing electron carriers which can yield negative Hall and Seebeck coefficients observed in high magnetic fields.

Rotation and lithium abundance of solar-analog stars. Theoretical analysis of observations

description: Rotational velocity, lithium abundance, and the mass depth of the outer convective zone are key parameters in the study of the processes at work in the stellar interior, in particular when examining the poorly understood processes operating in the interior of solar-analog stars. We investigate whether the large dispersion in the observed lithium abundances of solar-analog stars can be explained by the depth behavior of the outer convective zone masses, within the framework of the standard convection model based on the local mixing-length theory. We also aims to analyze the link between rotation and lithium abundance in solar-analog stars. We computed a new extensive grid of stellar evolutionary models, applicable to solar-analog stars, for a finely discretized set of mass and metallicity. From these models, the stellar mass, age, and mass depth of the outer convective zone were estimated for 117 solar-analog stars, using Teff and [Fe/H] available in the literature, and the new HIPPARCOS trigonometric parallax measurements. We determine the age and mass of the outer convective zone for a bona fide sample of 117 solar-analog stars. No significant on-to-one correlation is found between the computed convection zone mass and published lithium abundance, indicating that the large A(Li) dispersion in solar analogs cannot be explained by the classical framework of envelope convective mixing coupled with lithium depletion at the bottom of the convection zone. These results illustrate the need for an extra-mixing process to explain lithium behavior in solar-analog stars, such as, shear mixing caused by differential rotation. To derive a more realistic definition of solar-analog stars, as well as solar-twin, it seems important to consider the inner physical properties of stars, such as convection, hence rotation and magnetic properties.

description: Recent advances in next generation sequencing (NGS) technology provides the opportunity to rapidly understand whole genome methylation profile. However, there are challenges in handling and interpretation of the methylation sequence data because of its large volume and the consequences of bisulphite modification. Most of the current pipelines include a specific aligner to decode and quantify the fraction of methylated cytosine per base, further this quantitative data is studied for differential methylation and annotated for genomic features. We have examined the performance of three pipelines for alignment and differential methylation profiling using the published data from plant and animals. We compared the consistency across these tools and explored various visualization features. We also illustrate our in-house visualization based analytic tool for a higher quality comprehension of whole genome methylation profile. Our comparative study showcases the performance of the widely accepted tools and can guide the scientific community in choosing the appropriate method for their methylation data analysis.

description: Coeliccia octogesima, Selys (fig. 11 - 12 ). 1863. Selys, Bull. Acad. Belg. (2) 16, p. 157-158. — ♀ Singapore (Trichocnemis). 1886. Selys, Mém. cour. Acad. Belg. 38 (4), p. 117 - 118. — ♀ Singapore (Trichocnemis). 1932. Laidlaw, Rec. Ind. Mus. 34, p. 40-41 (orig. descr. quoted). Material studied: — 1 ♀ (ad., holotype), labelled: “ Sing”, (round, white), “ Mal. W.” (yellow, Selys ’ s hand), " Tr. octogesima S.” (yellow, S elys ), in the Brussels Museum. The type of this species is a ♀ in the Brussels Museum collection; and Laidlaw ’ s type-designations in this author’s revision of the genus Coeliccia, should be transposed. ( Laidlaw thinks it very unlikely that the two sexes described by de Selys should be conspecific). I have made sketches in the Brussels Museum of the prothorax, the quadrilateral spaces of fore and hinder wings, and of the colour-pattern of the synthorax of the type,, and I find these details well agreeing with those of a fine series of females collected by Mr.  Coomans de Ruiter in western Borneo. The last-mentioned examples I had associated with males from the same locality, identified by me as C. macrostigma, Laidlaw, with some misgivings. According to Laidlaw (loc. cit.), the ♀ of macrostigma (from Baram, Sarawak) is destroyed, which is extremely unfortunate. Since my specimens of macrostigma from West and East Borneo differ a little from the descriptions of that sex as given by Laidlaw , I hope to describe in detail both sexes of our series in a forthcoming paper on Bornean dragonflies. The middle lobe of the prothorax of the type of octogesima carries on either side a tooth-like, sub-acute lateral process (p), which rises close behind the junction of the anterior and median lobes, as in other species of the membranipesgroup. The lamina mesostigmalis is indicated in fig. 12 as l.m.

description: Photoionization by attosecond (as) extreme ultraviolet (xuv) pulses into the laser-dressed continuum of the ionized atom is commonly described in strong-field approximation (SFA), neglecting the Coulomb interaction between the emitted photoelectron (PE) and residual ion. By solving the time-dependent Schödinger equation (TDSE), we identify a temporal shift $δτ$ in streaked PE spectra, which becomes significant at small PE energies. Within an eikonal approximation, we trace this shift to the combined action of Coulomb and laser forces on the released PE, suggesting the experimental and theoretical scrutiny of their coupling in streaked PE spectra. The initial state polarization effect by the laser pulse on the xuv streaked spectrum is also examined.
