description: We consider a nonlinear polynomial regression model in which we wish to test the null hypothesis of structural stability in the regression parameters against the alternative of a break at an unknown time. We derive the extreme value distribution of a maximum-type test statistic which is asymptotically equivalent to the maximally selected likelihood ratio. The resulting test is easy to apply and has good size and power, even in small samples.

description: Ab initio total energy calculations within the framework of density functional theory have been performed for atomic hydrogen and oxygen chemisorption on the (0001) surface of double hexagonal packed americium using a full-potential all-electron linearized augmented plane wave plus local orbitals method. Chemisorption energies were optimized with respect to the distance of the adatom from the relaxed surface for three adsorption sites, namely top, bridge, and hollow hcp sites, the adlayer structure corresponding to coverage of a 0.25 monolayer in all cases. Chemisorption energies were computed at the scalar-relativistic level (no spin-orbit coupling NSOC) and at the fully relativistic level (with spin-orbit coupling SOC). The two-fold bridge adsorption site was found to be the most stable site for O at both the NSOC and SOC theoretical levels with chemisorption energies of 8.204 eV and 8.368 eV respectively, while the three-fold hollow hcp adsorption site was found to be the most stable site for H with chemisorption energies of 3.136 eV at the NSOC level and 3.217 eV at the SOC level. The respective distances of the H and O adatoms from the surface were found to be 1.196 Ang. and 1.164 Ang. Overall our calculations indicate that chemisorption energies in cases with SOC are slightly more stable than the cases with NSOC in the 0.049-0.238 eV range. The work functions and net magnetic moments respectively increased and decreased in all cases compared with the corresponding quantities of bare dhcp Am (0001) surface. The partial charges inside the muffin-tins, difference charge density distributions, and the local density of states have been used to analyze the Am-adatom bond interactions in detail. The implications of chemisorption on Am 5f electron localization-delocalization are also discussed.

Radiative cooling in relativistic collisionless shocks. Can simulations and experiments probe relevant GRB physics?
Creators: name: Medvedev, Mikhail V.

Subjects: subject: Astrophysics (astro-ph)

description: We address the question of whether numerical particle-in-cell (PIC) simulations and laboratory laser-plasma experiments can (or will be able to, in the near future) model realistic gamma-ray burst (GRB) shocks. For this, we compare the radiative cooling time, t_cool, of relativistic electrons in the shock magnetic fields to the microscopic dynamical time of collisionless relativistic shocks -- the inverse plasma frequency of protons, omega_pp^{-1}. We obtain that for t_cool*omega_pp^{-1}\lesssim ~few hundred, the electrons cool efficiently at or near the shock jump and are capable of emitiing away a large fraction of the shock energy. Such shocks are well-resolved in existing PIC simulations; therefore, the microscopic structure can be studied in detail. Since most of the emission in such shocks would be coming from the vicinity of the shock, the spectral power of the emitted radiation can be directly obtained from finite-length simulations and compared with observational data. Such radiative shocks correspond to the internal baryon-dominated GRB shocks for the conventional range of ejecta parameters. Fermi acceleration of electrons in such shocks is limited by electron cooling, hence the emitted spectrum should be lacking a non-thermal tail, whereas its peak likely falls in the multi-MeV range. Incidentally, the conditions in internal shocks are almost identical to those in laser-produced plasmas; thus, such GRB-like plasmas can be created and studied in laboratory experiments using the presently available Petawatt-scale laser facilities. An analysis of the external shocks shows that only the highly relativistic shocks, corresponding to the extremely early afterglow phase, can have efficient electron cooling in the shock transition. We emphasize the importance of radiative PIC simulations for further studies.

description: In our continuing attempts to understand theoretically various surface properties such as corrosion and potential catalytic activity of actinide surfaces in the presence of environmental gases, we report here the first ab initio study of molecular adsorption on the double hexagonal packed (dhcp) americium (0001) surface. Dissociative adsorption is found to be energetically more favorable compared to molecular adsorption. The most stable configuration corresponds to a horizontal approach molecular dissociation with the oxygen atoms occupying neighboring h3 sites, with chemisorption energies at the NSOC and SOC theoretical levels being 9.395 eV and 9.886 eV, respectively. The corresponding distances of the oxygen molecule from the surface and oxygen-oxygen distance were found to be 0.953 Ang. and 3.731 Ang., respectively. Overall our calculations indicate that chemisorption energies in cases with SOC are slightly more stable than the cases with NSOC in the 0.089-0.493 eV range. The work functions and net magnetic moments respectively increased and decreased in all cases compared with the corresponding quantities of the bare dhcp Am (0001) surface. The adsorbate-substrate interactions have been analyzed in detail using the partial charges inside the muffin-tin spheres, difference charge density distributions, and the local density of states. The effects, if any, of chemisorption on the Am 5f electron localization-delocalization characteristics in the vicinity of the Fermi level are also discussed.

Doch bei der Wahl des Studienortes zeigt sich, dass derzeit noch andere Informationsquellen häufiger verwendet und von der Mehrheit der Studienanfängern als wichtiger eingestuft werden. Nur 19,8 % der Studierenden haben sich bei der Studienortwahl im Internet informiert. Neben anderen Gründen lässt sich dieser geringe Anteil auf einen fehlenden Zugang und mangelnde Internetkenntnisse zurückführen. Nur 25,9 % der Studierenden haben bereits vor ihrem Studium mit dem Internet gearbeitet. Dies ändert sich mit dem Beginn des Studiums schlagartig und der Anteil derjenigen, die das Internet nutzen, hat sich bereits im ersten Semester mit 62,8 % mehr als verdoppelt. Die Kommunikation per E-Mail ist dabei die häufigste Nutzungsform, gefolgt von der Literaturrecherche und Informationsbeschaffung für das Studium. Kommerzielle Anwendungen (Online-Shopping, Online-Banking) werden von den Studierenden dagegen zumeist gemieden.
When efficiency results in redistribution: the conflict over the sin-gle services market

description: The discussion of the Services Directive from 2004 onwards showed an unprecedented extent of politicization of a single-market issue. Coinciding with the 2004 Eastern Enlargement round, the easing of the services freedom through the directive raised significant redistributive issues, given the differences in labour costs. The arti-cle analyzes why mutual recognition is so controversial in services, arguing that the relationship among member states, between governments and their citizens, and among differently regulated EU citizens matters. Partly, the directive lessens the risk of redistribution through the institutionalization of administrative cooperation between the home and the host member state. Partly, the directive fails, as member states may be forced to discriminate against their population in the name of the internal market.

description: The gas supply from the cosmic web is the key to sustain star formation in galaxies. It remains to be explored how the cosmic large-scale structure (LSS) effects on galaxy evolution at given local environments. We examine galaxy specific star formation rate as a function of local density in a LSS at $z=0.735$ in the Extended Chandra Deep Field South. The LSS is mapped by 732 galaxies with $R<24$\,mag and redshift at $0.72\le z \le 0.75$ collected from the literature and our spectroscopic observations with Magellan/IMACS, consisting of five galaxy clusters/groups and surrounding filaments over an area of $23.9 \times22.7$\,co-moving\,Mpc$^2$. The spread of spectroscopic redshifts corresponds a velocity dispersion of 494\,km\,s$^{-1}$, indicating the LSS likely to be a thin sheet with a galaxy density $\gtrsim 3.9$ times that of the general field. These clusters/groups in this LSS mostly exhibit elongated morphologies and multiple components connected with surrounding filaments. Strikingly, we find that star-forming galaxies in the LSS keep star formation at the same level as field, and show no dependence on local density but stellar mass. Meanwhile, an increasing fraction of quiescent galaxies is detected at increasing local density in both the LSS and the field, consistent with the expectation that galaxy mass and local dense environment hold the key to quench star formation. Combined together, we conclude that the cosmic environment of the LSS overtakes the local environment in remaining galaxy star formation to the level of the field.

description: The Court of Justice of the European Union is an important motor of integration, and is said to be particularly strong in those cases, where the Council shows an inability to act. What is the relevance of the Court to Social Europe? Europeanization studies analyse how member states change due to European integration. Judicial Europeanization is a topic that is under-explored in the literature. Using a case-study approach, this paper analyses the Zambrano case, one of the most notable recent cases of judicial activism of the CJEU with regard to EU citizenship rights. Though the literature often assumes that member states only reluctantly embrace the requirements of case law, the Irish government immediately held its administration to implement the required changes. Analysing this case in greater detail and comparing it to the responses of several other member states promises to shed some light on the under-explored question of how Europeanization through case law proceeds, and what the Court may contribute to social Europe.

Free movement, the welfare state, and the European Union's over-constitutionalization: Administrating contradictions

description: The European Union (EU) has to reconcile free movement rights with national welfare states. Case law of the European Court of Justice (ECJ) has broadened rights to welfare of economically inactive or marginally active EU citizens. Applying the Court’s jurisprudence, which is vague and specific at the same time, poses serious challenges for national administrations. Vague criteria for individual assessments have to be translated into mass procedures. And legislative corrections of the case law are often foreclosed given the EU’s skewed separation of powers and the over-constitutionalization of European law, where crucial policy choices are taken by the Court’s Treaty interpretation. We compare the British and the German approaches and show that ECJ case law impacts through different channels, but triggers similar challenges for national administrations.
Adaptive predictive delta coder combining syllabic adaptation and a self-adaptive quantizer
Creators: name: Schellenberg, Walter Ulrich
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this thesis is to evaluate an adaptive differential encoder for digital communication channels. The redundancy reduction technique used in this coder is not restricted to speech signals only. However, it was optimized for such signals with the objective of keeping the bit-rate as low as possible. In the transmitter, the signal redundancy is reduced in two steps. First, taking advantage of the quasi-periodicity of speech signals, the current signal value is predicted from the value one period before. Secondly, the difference between this prediction and the true value is estimated by a prediction based on the two previous differences. The error of this second prediction is quantized and transmitted to the receiver. The receiver produces a replica of the original signal by adding the received error signal to the predicted value. The adaptation of the quantizer step size has an exponential characteristic and contains a delay of one sampling period. These two features give rise to instabilities and poor reproduction of high signal frequencies, the latter being an inherent characteristic of this quantizer. The stability problem could not be solved theoretically because the nonlinearity and delay in the quantizer render the system mathematically intractable. By restricting the maximum quantizer level and adding a direct feedback of the step size to the second predictor, the instabilities are restricted to acceptable limits. The coder was simulated on a digital computer and optimized for sampling rates of 8, 12, and 16 kHz using objective calculations of the signal-to-quantization noise ratio as well as subjective preference tests. In some cases the calculated S/Q ratios allow no distinction in performance, but the subjective evaluations exhibit strong differences in preference. This observation emphasizes the necessity to examine the subjective performance of such voice systems. Comparisons with speech from a log PCM encoder indicate that at a sampling rate of 8 kHz, the subjective quality of the reconstructed speech is slightly superior to that of log PCM encoded at 3 bits per sample and the same sampling frequency. It is estimated that at a sampling rate of 8 kHz, an additional 3800 bits/sec are required to transmit the four coder parameters. The suggested final transmission bit-rate is therefore 11.8 kbits/sec. Thus, a data compression of approximately two to one has been achieved. Included are suggestions for reducing the bit-rate to 9.6 kbits/sec with minimal degradation in speech quality below that achieved using 11.8 kbits/sec.

description: The compactness of weak solutions to the magnetohydrodynamic equations for the viscous, compressible, heat conducting fluids is considered in both the three-dimensional space $\R^3$ and the three-dimensional periodic domains. The viscosities, the heat conductivity as well as the magnetic coefficient are allowed to depend on the density, and may vanish on the vacuum. This paper provides a new idea to show the compactness of solutions of viscous, compressible, heat conducting magnetohydrodynamic flows, derives a new entropy identity, and shows that the limit of a sequence of weak solutions is still a weak solution to the compressible magnetohydrodynamic equations.

description: There is evidence that stars and browns dwarfs grow through episodic rather than continuous gas accretion. However, the role of episodic accretion in the formation of brown dwarfs remains mostly unexplored. We investigate the role of episodic accretion, triggered by the magnetorotational instability in the inner disk regions, resulting in episodic outbursts during the formation of brown dwarfs, and its implications for their early formation stages. We use hydrodynamical simulations coupled with a sub-grid accretion model to investigate the formation of young proto-brown dwarfs and protostars, taking into account the effects of episodic accretion resulting in episodic radiative feedback, i.e. in luminosity outbursts. The formation timescale for proto brown dwarfs is at least one order of magnitude shorter than that of protostars. Episodic accretion leads to a shorter main accretion phase compared to continuous accretion in brown dwarfs, whereas the opposite is true for low-mass stars. Episodic accretion can accelerate early mass accretion in proto-brown dwarfs and protostars, but it results in less massive objects by the end of the main phase compared to continuous accretion. We find an approximately linear correlation between an object's mass at the end of the main accretion phase and the timing of the last episodic outburst: later events result in more massive brown dwarfs but less massive low-mass stars. Episodic outbursts have a stronger effect on brown dwarf-forming cloud cores, with the last outburst essentially splitting the brown dwarf evolution into a short high-accretion and a much longer low-accretion phase.

Towards spoken English : a computer based synthesizer for a reading machine for the blind
Creators: name: Yeung, James Man Chung
Publisher: name: University of British Columbia
Year: 2010

description: A speech synthesizer has been developed to synthesize real-time speech directly from letter information. The synthesizer was implemented on a PDP-12 digital computer and its peripheral devices. Synthetic speech was produced by the concatenation of 33 basic phonemes. These phonemes were processed by a segmentation program which was developed to extract, record, display and store them: the original speech samples were treated similarly. The letter information from the output of a letter recognizer was stored in an input stack (or buffer) until a complete word has been received. Then the input word was synthesized by a synthesis program which assigned phonemes to the word according to the stored dictionary and the general grapheme-phoneme correspondence rules written in the program. A dictionary containing words that were not pronounced according to the above general rules, and in addition, a list of phoneme equivalents, were stored in a disk file system. The general rules were set up according to the most frequent grapheme-phoneme transcriptions and a frequency study of the first 1,000 words of the Thorndike word list. The synthesizer was capable of synthesizing over 90% of spoken English speech accurately and at the same time could be understood by the listener after a short period of training in spite of the mechanical sounding dialect which resulted from the incorrect pronunciation of some words. An intelligibility test using isolated words, sentences, and short passages generated by the synthesizer, was given to six subjects. The results showed that over 90% of the isolated words, 95% of the sentences and 98% of the short passages could be recognized by the test subjects after approximately one hour of training.

It was found that each of these methods is most effective for certain length of prognosis. For short-time prediction ARIMA algorithm yields more accurate prognosis, and for long-time one extrapolation is preferable. So, the combined algorithm is being used in practice of IAA EOP Service. The accuracy of prognosis is close to accuracy of IERS algorithms. For prediction of nutation the program KSV-1996-1 by T. Herring is being used.

Political Education. The Global Education of Citizen through Active Citizenship

description: The human being grows in relationship with others of its fellows, and it is by virtue of this relationship that it receives a particular cultural heritage and acquires its own identity, differentiating itself, finding its own space of freedom and autonomy allowing it to interact and extend its own network of relations. In such a dynamic of reciprocity, the man realizes himself as such as a conscious member of a “social body”, i.e. of a radical society in an organic human context, which has become nowadays a clearly planetary one, by virtue of the unpublished migration flows and obvious interdependence of the Planet. The education is a line of human civility and it causes that grounds of anonymity, fears, consumerism, prejudice, haste, indifference, abuse, insecurity, solitude, become grounds of hospitality, trust, sharing, security, friendship, and brotherhood. The patterns of political education having prevailed so far are: the academic model with its explanation and dissent in the abstract of a great deal of knowledge, and that of the laboratory, which tilts and leans over, even by moments of simulation, toward vital worlds of operational policy. It is now manifested a widespread social demand about the necessity to provide to everybody, but especially in the range of basic youth socio-political information, an equipment of historical and values’ nature, and by providing comparative elements on the different socio-political matrices and traditions, raising the incentive at a renewing and increasingly conscious commitment in the face of growing difficulties, inherent to the political perspectives disputed so far in the world. It is necessary to refocus and reestablish a political culture uniting the breath of the ideal with the reality of administrative experience, supporting this political culture with the contribution of a dynamic and open reflection, capable of understanding the reality.

description: Radio Astronomy is undergoing a renaissance, as the next-generation of instruments provides a massive leap forward in collecting area and therefore raw sensitivity. However, to achieve this theoretical level of sensitivity in the science data products we need to address the much more pernicious systematic effects, which are the true limitation. These become all the more significant when we consider that much of the time used by survey instruments, such as the SKA, will be dedicated to deep surveys. CHILES is a deep HI survey of the COSMOS field, with 1,000 hours of VLA time. We present our approach for creating the image cubes from the first Epoch, with discussions of the methods and quantification of the data quality from 946 to 1420MHz -- a redshift range of 0.5 to 0. We layout the problems we had to solve and describe how we tackled them. These are of importance as CHILES is the first deep wideband multi-epoch HI survey and it has relevance for ongoing and future surveys. We focus on the accumulated systematic errors in the imaging, as the goal is to deliver a high-fidelity image that is only limited by the random thermal errors. To understand and correct these systematic effects we ideally manage them in the domain in which they arise, and that is predominately the visibility domain. CHILES is a perfect test bed for many of the issues we can expect for deep imaging with the SKA or ngVLA and we discuss the lessons we have learned.

The rim of the Bar shows very corrugated structures made of small-scale H2 dissociation fronts (DFs). The [CI] 609 um emission peaks very close (~0.002 pc) to the main H2-emitting DFs, suggesting the presence of gas density gradients. These DFs are also bright and remarkably similar in C2H emission, which traces "hydrocarbon radical peaks" characterized by very high C2H abundances, reaching up to several x10^-7. The high abundance of C2H and of related hydrocarbon radicals, such as CH3, CH2, and CH, can be attributed to gas-phase reactions driven by elevated temperatures, the presence of C+ and C, and the reactivity of FUV-pumped H2. The hydrocarbon radical peaks roughly coincide with maxima of the 3.4/3.3 um AIB intensity ratio, a proxy for the aliphatic-to-aromatic content of PAHs. This implies that the conditions triggering the formation of simple hydrocarbons also favor the formation (and survival) of PAHs with aliphatic side groups, potentially via the contribution of bottom-up processes in which abundant hydrocarbon radicals react in situ with PAHs. Ahead of the DFs, in the atomic PDR zone (where [H]>>[H2]), the AIB emission is the brightest, but small PAHs and carbonaceous grains undergo photo-processing due to the stronger FUV field. Our detection of trace amounts of C2H in this zone may result from the photoerosion of these species. This study provides a spatially resolved view of the chemical stratification of key carbon carriers in a PDR. Overall, both bottom-up and top-down processes appear to link simple hydrocarbon molecules with PAHs in molecular clouds; however, the exact chemical pathways and their relative contributions remain to be quantified.

description: Excerpts from the report Preface: This is a report on one of six communities which were studied contemporaneously by six different participant observers or field workers during the year 1939. Each study was sufficiently independent of the other five to warrant, in fact make desirable, separate treatment and publication. The reader, however, will gain full understanding of the findings only when he has read the six studies as a group. El Cerrito is a stable community culturally, in fact almost a cultural island. It has, however, suffered severely because it has lost a large portion of the land which supported it and because it is poorly equipped with technologies to meet the competition of other producing areas.

Separation of Equilibration Time-Scales in the Gradient Expansion

description: We study thermalization by applying gradient expansion to the Kadanoff-Baym equations of the 2PI effective action to two-loop in a theory with Dirac fermions coupled to scalars. In addition to those chemical potentials which equilibrate in the on-shell limit, we identify modes which are conserved in this approximation, but which relax when off-shell effects are taken into account. This implies that chemical equilibration does not require higher loop contributions to the effective action and is compatible with the gradient expansion. We explicitly calculate the damping time-scales of both, on- and off-shell, chemical equilibration rates. It is shown that off-shell equilibration is suppressed by the thermal width of the particles in the plasma, which explains the separation of on- and off-shell chemical equilibration time-scales.

Causal Interaction between the subsurface rotation rate residuals and radial magnetic field in different timescales

description: We studied the presence and spatiotemporal characteristics and evolution of the variations in the differential rotation rates and radial magnetic fields in the Schwabe and Quasi-biennial-oscillation (QBO) timescales. To achieve these objectives, we used rotation rate residuals and radial magnetic field data from the Michelson Doppler Imager on the Solar and Heliospheric Observatory and the Helioseismic and Magnetic Imager on the Solar Dynamics Observatory, extending from May 1996 to August 2020, covering solar cycles 23 and 24, respectively. Under the assumption that the radial surface magnetic field is non-local and the differential rotation is symmetric around the equator, our results suggest that the source region of the Schwabe cycle is confined between $\sim$30$^{\circ}$ N and S throughout the convection zone. As for the source region of the QBO, our results suggest that it is below 0.78R$_{\odot}$.

description: The full potential all electron linearized augmented plane wave plus local orbitals (FP-LAPW + lo) method, as implemented in the suite of software WIEN2K, has been used to systematically investigate the structural, electronic, and magnetic properties of the actinide compounds AnN (An = Ac, Th, Pa, U, Np, Pu, Am). The theoretical formalism used is the generalized gradient approximation to density functional theory (GGA-DFT) with the Perdew-Burke-Ernzerhof (PBE) exchange-correlation functional. Each compound has been studied at six levels of theory: non-magnetic (NM), non-magnetic with spin-orbit coupling (NM+SOC), ferromagnetic (FM), ferromagnetic with spin-orbit coupling (FM+SOC), anti-ferromagnetic (AFM), and anti-ferromagnetic with spin-orbit coupling (AFM+SOC). The structural parameters, bulk moduli, densities of states, and charge distributions have been computed and compared to available experimental data and other theoretical calculations published in the literature. The total energy calculations indicate that the lowest energy structures of AcN, ThN, and PaN are degenerate at the NM+SOC, FM+SOC, and AFM+SOC levels of theory with vanishing total magnetic moments in the FM+SOC and AFM+SOC cases, making the ground states essentially non-magnetic with spin-orbit interaction. The ground states of UN, NpN, PuN, and AmN are found to be FM+SOC at the level of theory used in the present computations. The nature of the interactions between the actinide metals and nitrogen atom, and the implications on 5f electron delocalization and localization are discussed in detail.

Field-induced optical anisotropy in thin niobium oxide films
Creators: name: Yee, Kai Kwan
Publisher: name: University of British Columbia
Year: 2010

description: An automated ellipsometer was used to study field-induced optical anisotropy in anodic niobium oxide films. The oxide films were found to change from the optically isotropic state to the optically anisotropic state when an electric field was applied normal to the film surface. The anisotropic refractive indices of the oxide films decreased quadratically while the thickness of the films increased quadratically with the applied field. The quadratic electro-optic coefficients were determined. The changes in refractive indices and in thickness of the oxide films were found to be independent of time. Field recrystallization of the anodic niobium oxide films was investigated using a scanning electron microscope. The results are compared with those reported for anodic tantalum oxide films in the published literature.

description: We report line-by-line control of a coherent discrete spectrum (Raman sidebands) with a frequency spacing of 10.6 THz that is produced by an adiabatic Raman process. We show that the spectral phase of the Raman sidebands is finely controlled to the target (flat relative-spectral-phase). This is achieved by employing a combination of a spatial phase controller and a spectral interferometer, which are specifically designed for a high-power discrete spectrum. We also show that such spectral-phase control produces a train of Fourier transform limited pulses with an ultrahigh repetition rate of 10.6 THz in the time domain.

Bulk viscosity effects on elliptic flow

description: The effects of bulk viscosity on the elliptic flow $v_{2}$ are studied using realistic equation of state and realistic transport coefficients. We find that thebulk viscosity acts in a non trivial manner on $v_{2}$. At low $p_{T}$, the reduction of $v_{2}$ is even more effective compared to the case of shear viscosity, whereas at high $p_{T}$, an enhancement of $v_{2}$ compared to the ideal case is observed. We argue that this is caused by the competition of the critical behavior of the equation of state and the transport coefficients.
