Повний текст джерелаIn reactor core design, a gap exists between the manual calculation of few-group constants and the many-group calculation, by large computer programs. A method is needed by which group constants may be calculated easily and quickly. The FASPEC program is designed to reduce the amount of manual calculation and to complement the large program by reducing the number of times the large program must be run to achieve desired results.
The program calculates group constants from 940 microgroups, collapsing to any user-specified number of macrogroups up to 47. FASPEC is based on group-averaged flux calculations by a solution of the Infinite medium neutron transport equation. Flux contributions from inelastic scatter are included while those from neutron upâ scatter are not. The energy spectrum considered is from 10 MeV to 0.625 eV. Required input is the atomic number density of each isotope, the number of macrogroups desired and the upper and lower microgroup numbers of each macrogroup. Input is facilitated by prompting in each case. Cross section look-up tables were provided by the Very Improved Monte Carlo code (VIM) for a mid-range Infinite hexagonal lattice. Self-shielding effects are included indirectly. A brief user's guide is provided.
Group constants calculated and stored for either terminal display or printed output are group number, lowest energy of the group, macroscopic removal cross section, macroscopic absorption cross section, diffusion coefficient, flux, macroscopic fission cross section, v, the average number of neutrons emitted per fission, and vΣf.

Повний текст джерелаEl estudio exploró la presencia de diferentes patrones de cambio en una muestra de pacientes que recibió terapia cognitiva para la depresión en dos formatos secuenciales: grupal e individual. Nuestra hipótesis fue que algunos pacientes responderían mejor a la terapia grupal que a la individual, y que para otros pacientes se encontraría el patrón opuesto. OBJETIVO: Identificar patrones diferenciales de respuesta, describir las diferencias entre las características de los pacientes en cada patrón y, desde estas características, predecir la pertenencia de los pacientes a cada patrón. También quisimos evaluar la relación entre cada patrón y el resultado de la terapia al final del tratamiento y al seguimiento. MÉTODO: 108 adultos que cumplieron criterios para el diagnóstico de trastorno depresivo mayor y/o distimia completaron los tratamientos como parte de un ensayo clínico aleatorizado que combinaba terapia grupal e individual. Los pacientes fueron evaluados con la Entrevista Clínica Estructurada para los Trastornos del Eje I del DSM-IV, el Inventario de Depresión de Beck – II, el Clinical Outcome in Routine Evaluation, la Escala de Evaluación de la Actividad Global, y la técnica de la rejilla. Se utilizaron modelos de crecimiento mixtos para identificar los patrones de cambio en cada fase de tratamiento. Se utilizaron modelos lineales mixtos y análisis de la varianza de medias repetidas para estimar las diferencias en las características de los pacientes entre cada patrón. A través de regresión logística multinomial se estimaron modelos predictivos de los patrones de cambio desde las características iniciales de los pacientes. Finalmente, a través de regresión lineal jerárquica se estimó el poder predictivo de cada patrón para explicar los resultados de la terapia al final del tratamiento, al seguimiento a los tres meses y al seguimiento a un año. RESULTADOS: Se obtuvo una solución de tres clases: quienes mejoraron en terapia grupal, quienes mejoraron en terapia individual y quienes no mejoraron. Los pacientes pertenecientes a cada patrón se diferenciaron en el nivel inicial de sintomatología, malestar psicológico, funcionamiento, discrepancia yo-ideal, aislamiento social auto- percibido y construcción conflictiva del sí-mismo. Algunas de estas variables también funcionaron como predictores de la pertenencia de los pacientes a cada patrón. Más de la mitad de la varianza explicada del resultado de la terapia al final del tratamiento y al seguimiento a un año fue representada por las puntuaciones iniciales de depresión y los patrones de cambio. CONCLUSIONES: Los resultados tendieron a apoyar nuestra hipótesis acerca de patrones diferenciales de respuesta en terapia cognitiva. Los perfiles de los pacientes que obtuvieron mejores resultados en terapia grupal que en terapia individual para depresión pudieron ser identificados.

Esta pesquisa põe seu foco principal na dinâmica de inclusão e exclusão em grupos de adolescentes no contexto escolar. Os grupos são construídos como pequenos agrupamentos de amigos cuja estrutura tem um caráter fluido e dinâmico e que se relacionam entre si, formando tramas ou redes de relacionamentos. Nessa dinâmica, o adolescente precisa se encaixar e ser aceito, o que nem sempre ocorre com êxito, pois o grupo que funciona como elemento agregador, também é aquele que pode promover a exclusão. Nesse sentido, a pesquisa busca ouvir os adolescentes sobre a dinâmica da formação desses agrupamentos, assim como sobre questões relacionadas aos processos de inclusão e exclusão. Trata-se de um estudo de cunho etnográfico que procura aliar a perspectiva sócio-histórica de construção de identidades, na qual as mesmas são construídas dentro de um contexto social, cultural e histórico, a uma abordagem microanalítica com enfoque na análise de narrativas em interação. Para a análise de narrativas, a pesquisa utiliza categorias labovianas de forma flexível, em especial a de avaliação. É observada a performance narrativa/identitária, com foco na avaliação, e tal análise se faz com base no método de análise de posicionamentos, o qual permite observar como os indivíduos se posicionam em relação às suas identidades e às identidades de seus interlocutores. A pesquisa, enfim, dimensiona a comunidade aqui estudada como microcosmo que possibilita uma perspectiva local e cria inteligibilidade sobre questões ligadas à cultura adolescente, mormente sobre os processos de inclusão e exclusão que se dão na dinâmica de formação de grupos de adolescentes na escola.
This research puts its main focus on the dynamic process of inclusion and exclusion in adolescent peer groups in the school context. Peer groups are constructed as fluid and dynamic small groupings of friends, which relate to one another, forming relationship nets. In this dynamic process, adolescents have to fit in and be accepted. This does not always occur successfully because the same group which functions as a binding element, may also promote exclusion. In this sense, the research aims at listening to adolescents not only about the dynamic formation of those groupings, but also about inclusion and exclusion processes. This ethnography-based study allies a socio-historical perspective on identity construction in which identities are constructed within a social, cultural and historical context, with a focus on the analysis of narratives in interaction. For the analysis of narratives, this research uses Labovian categories flexibly, namely, evaluation. It also observes narrative/identity performance with a focus on evaluation and that observation is based on the positioning approach to narrative analysis, which allows for the analysis of the ways individuals position themselves in relation to their identities and the identities of their interlocutors. The research frames the small community studied here as a microcosmos which gives rise to a local perspective as well as intelligibility about issues concerning youth culture, especially those concerning the processes of inclusion and exclusion that take place within the dynamics of adolescent peer group formation in school.

An experimental study was performed to understand lower limb movement patterns between older and young adults, and to explore a new metric of coordination. Lower limb and torso movement in an older and younger population was captured using both IMU sensors and an optical tracking system. Only data from the optical method was processed and analyzed for this thesis. The participants executed several trials of a Timed-Up-and-Go test (TUGT), a 10 meter Walk Test (10MWT), and a Standing Balance Test (SBT). This paper specifically analyzed data from seven of the participants when executing the TUG test. The Relative Coordination Metric (RCM) from Hip to Knee and from Knee to Ankle was briefly explored for one subject from each age group. Several qualitative differences in motion were seen between the younger subject and the older subject for the Hip-Knee RCM, while similarities were identified for the Knee-Ankle RCM. The TUG time for the younger age group (M = 11.48s, SD = 1.26s) and the older age group (M = 12.06s, SD = 0.69s) was also compared and it was found that they were significantly different (t =1.998, p = 0.017).

The importance of multiplicity adjustment has gained wide recognition in modern scientific research. Without it, there will be too many spurious results and reproducibility becomes an issue; with it, if overtly conservative, discoveries will be made more difficult. In the current literature on repeated testing of multiple hypotheses, Bonferroni-based methods are still the main vehicle carrying the bulk of multiplicity adjustment. There is room for power improvement by suitably utilizing both hypothesis-wise and analysis- wise dependencies. This research will contribute to the development of a natural group-sequential extension of the classical stepwise multiple testing procedures, such as Dunnett’s stepdown and Hochberg’s step-up procedures. It is shown that the proposed group-sequential procedures strongly control the familywise error rate while being more powerful than the recently developed class of group-sequential Bonferroni-Holm’s procedures. Particularly in this research, a convexity property is discovered for the distribution of the maxima of pairwise null P-values with the underlying test statistics having distributions such as bivariate normal, t, Gamma, F, or Archimedean copulas. Such property renders itself for an immediate use in improving Holm’s procedure by incorporating pairwise dependencies of P-values. The improved Holm’s procedure, as all stepdown multiple testing procedures, can also be naturally extended to group-sequential setting.

Повний текст джерелаEnsuring that psychological interventions are well received and effective among ethnically and culturally diverse groups is at the forefront of psychological research. This study is a nonexperimental, posttest evaluation of differences between European American and ethnocultural group parents' perceptions of the Family Check-Up (FCU), a family-centered, ecologically and community-based intervention that provides family assessment, support, and motivation to change for families coming to counseling. Research has demonstrated the effectiveness of the FCU but has yet to evaluate parent perceptions of the FCU. This study examines features of intervention implementation that lead to treatment satisfaction and adherence by evaluating parent perceptions of (a) the FCU intervention, (b) therapist interpersonal qualities, and (c) therapist multicultural competence. Both parent and observational coder ratings of the intervention were assessed along these dimensions. In the first year of a longitudinal study of the FCU, data were collected from parents of children who attended three public middle schools in a metropolitan area of the Pacific Northwest. Within-subjects analyses were conducted to assure measurement validation and treatment fidelity. A between-subjects multivariate analysis of variance was utilized to examine ethnocultural group differences. Results revealed that all measures demonstrated high internal consistency reliability, high interscale correlations, and good construct validity. Results revealed high interrater agreement between parent ratings of treatment receipt and coder ratings of treatment delivery, indicating treatment fidelity. Results revealed no statistically significant differences in parent perceptions of the FCU intervention, regardless of parent ethnocultural group. Additional analyses demonstrated that observational coders rated family consultants who worked with ethnocultural group parents higher in multicultural competence than those who worked with European American parents. In summary, study results suggest (a) that the measures developed and adapted for this investigation were reliable and valid, and (b) that we found no evidence of perceived differences in the FCU intervention across ethnocultural group and European American parents. The FCU continues to be an intervention that can be successfully implemented among ethnically and culturally diverse families.

Повний текст джерелаObjective: Assess obsessive-compulsive disorder (OCD) patients' long term response to treatment after five years of cognitive-behavioral group therapy (CBGT) or sertraline 100mg/day. Methods: Fifty patients who completed 12 two-hour weekly CBGT sessions or had sertraline 100 mg/day for the same period were followed up in a naturalistic study. The severity of symptoms were evaluated after five years from the conclusion of treatment by Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Clinical Global Impressions Scale - Severity underscore (CGI-S), Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and quality of life with World Health Organization Quality of Life Assesment – Abreviated Version (WHOQOL-bref). Results: Both patients treated with CBGT and those treated with sertraline showed a significant reduction in the severity of symptoms and maintained therapeutic gains five years after the end of treatment. We also noticed an increase in the use of medication in the CBGT group (p<0.001) during the follow-up period and a search for psychotherapeutic treatment in the group who took sertraline (p=0.084), although this latter occurred at a non-significant level. Results indicated that 61.9% of patients continued using or started using the medication and 41.5% started or continued with the CBT. There was a significant increase of remissive patients in the sertraline group (p=0.046), while the same did not occur in the CBGT group (p=0.083). There was an increase in the scores of different quality of life domains (QL) regardless of the group. Conclusions: Our results showed that both the group that underwent CBGT and the one that took sertraline maintained their levels of improvement at the end of the five-year treatment. As well, an increase in all QL domains was noticed. Perhaps this may be put down to the fact that over half the patients continued with the treatment during the follow-up period.

Повний текст джерелаThe SiGeSn semiconductor material system has recently attracted great interest due to its prospective potential for use in optoelectronics, electronics, and photovoltaics. While the binary alloy Si(x)Ge(1-x) and Ge(1-y)Sn(y) have already been well studied, the properties of bulk and heterostructures involving the Ge(1-x-y)Si(x)Sn(y) ternary alloy are largely unknown. In this thesis, we present the results of three theoretical/experimental-theoretical investigations concerning the SiGeSn material system. First, we investigate the compositional dependence of the direct band-gap of Ge(1-x-y)Si(x)Sn(y) alloys. Based on Rutherford backscattering, x-ray diffraction, and photoluminescence (PL) measurement of Ge(1-x-y)Si(x)Sn(y) alloys lattice-matched to Ge, we describe the compositional dependence of the band gap using a quadratic equation. We predict Ge(1-x-y)Si(x)Sn(y) alloys lattice-matched to Ge to be direct-band-gap semiconductors for Sn concentrations larger than 12%. Secondly, we investigate the band alignment between the elemental semiconductors Si, Ge, and Sn. Performing bulk and interface calculations using density functional theory (DFT) in combination with the local density approximation (LDA), we attempt to calculate the valence band offset between the elemental semiconductors. We find that the Kohn-Sham based DFT-LDA calculations are flawed by the underestimation of the band-gaps of the elemental semiconductors, which leads to a false broken gap band alignment between Ge and Sn. Third, we study the PL of ultrathin Ge multiple quantum well (multiple-QW) structures grown on Si. To understand the excitation density and temperature related shifts of the PL spectra of the sample, we develop a self-consistent multivalley effective mass model. Using second-order perturbation theory, we calculate the indirect phonon-assisted radiative spontaneous recombination rate together with the no-phonon peak energy and compare our results to the experimental results.

The study of three Chinese multinational enterprises – the Haier Group, Huawei Technologies and TCL Corporation – is conducted in the framework of the Dynamic-Capability View (DCV). It aims at identifying the nature and the foundations of the dynamic capabilities developed by these corporations during the internationalization process.This process is characterized by the combination of a significant investment in technological innovation and an accelerated internationalization, jointly contributing to creating and sustaining of competitive advantage. These two elements of the corporate strategies benefit from the strong support of the Chinese government

Повний текст джерелаThis work aimed on the development of dual-mode labelling method that combines X-ray photoelectron spectroscopy (XPS) with fluorescence measurements for surface functional group quantification. Label dyes combining robust fluorescence properties with high fluorine contents were investigated towards their selective reaction with surface amino groups and the lead candidate subjected to detailed analysis on a surface. Fluorescence quenching precluded a detailed investigation of the capabilities of dual-mode labelling, despite providing sufficient signal in XPS and fluorescence scanning. The fabrication of surfaces using vapour deposition (VD) of silanes in toluene was optimized under aid of contact angle measurements. Binary mixtures of mono-alkoxy silanes were used to prepare surfaces with variable functional group density. Treatment with the label dye showed that XPS and fluorescence provide a linear overlap in signal generation over at least one order of magnitude. The combination of synchrotron radiation XPS (SR-XPS) and total reflection X-ray fluorescence spectroscopy (TXRF) provided an absolute and traceable quantification . Different model surfaces based on trialkoxy silanes showed strong fluorescence quenching. A fluorescence lifetime based correction was developed to account for such quenching effects. Additionally, the application of spectrophotometry provided a independent method of quantification for the surface bound dye and in combination with information obtained from XPS, to determine the surface functional group density. With cavity ring-down spectroscopy (CRDS), a laser based technique for highly sensitive and spatially resolved absorption measurements on transparent substrates could be developed and applied in a proof-of-concept. A modular system for the fabrication of label dyes with adjustable spectral properties and different binding sites was investigated using prototype candidates to prove the general applicability of such systems.
Lähnemann, Jonas. "Luminescence of group-III-V nanowires containing heterostructures." Doctoral thesis, Humboldt-Universität zu Berlin, Mathematisch-Naturwissenschaftliche Fakultät I, 2013. http://dx.doi.org/10.18452/16797.
Повний текст джерелаIn this thesis, the spectral and spatial luminescence distribution of heterostructures in self-induced nanowires (NWs) is investigated by cathodoluminescence spectroscopy in a scanning electron microscope. This method is complemented by data from both continuous and time-resolved micro-photoluminescence measurements. Three different structures are considered: (i) GaAs NWs containing segments of the wurtzite (WZ) and zincblende (ZB) polytypes, (ii) GaN microcrystals overgrown on GaN NWs, and (iii) (In,Ga)N insertions embedded in GaN NWs. The polytypism of GaAs NWs results in complex emission spectra. The observation of luminescence either exclusively at energies below the ZB band gap or also at higher energies is explained by differences in the distribution of ZB and WZ segment thicknesses. Measurements at room temperature suggest that the band gap of WZ GaAs is at least 55 meV larger than that of the ZB phase. The luminescence spectra of the GaN microcrystals contain distinct emission lines associated with stacking faults (SFs). SFs essentially constitute ZB quantum wells of varying thickness in a WZ matrix and it is shown that their emission energy is dominated by the spontaneous polarization. Through a detailed statistical analysis of the emission energies of the different SF types, emission energies of 3.42, 3.35 and 3.29 eV are determined for the intrinsic (I1 and I2) as well as the extrinsic SFs, respectively. From the corresponding energy differences, an experimental value of -0.022C/m² is derived for the spontaneous polarization of GaN. The importance of both carrier localization and the quantum confined Stark effect induced by the piezoelectric polarization is shown for the luminescence of (In,Ga)N insertions in GaN NWs. Not only localized excitons, but also electrons and holes individually localized at different potential minima contribute to the observed emission.

Повний текст джерелаThis work covers the MBE growth and characterization of group III-nitride nanostructures. The work begins with the catalyst-free growth of GaN nanowires (NWs) on Si(111) by plasma-assisted MBE. The importance of substrate preparation and the formation of an amorphous SiN interlayer are described. GaN NWs are shown to nucleate as spherical islands and to furhter undergo a shape transition towards the NW geometry. The amorphous interlayer leads to a loss in epitaxial alignment and thus to NW tilt and coalescence. Coalescence leads to the formation of dislocations and stacking faults (SFs) in the NWs which greatly affect their optical properties. Dislocations are shown to have a detrimental effect on the optical quality, whereas SFs are shown to have a characteristic emission wavelength. Epitaxial growth of GaN on Si(111) can be achieved by using an AlN buffer layer. The nucleation and growth GaN NWs on AlN-buffered Si(111) is shown to happen via the pseudomorphical nucleation of spherical islands. As these islands grow, they undergo several characteristical shape changes, with the formation of facets in order to elastically relieve the lattice-mismatch induced strain. At a critical island size (and thus strain level), plastic relaxation happens by the formation of a misfit dislocation at the AlN/GaN interface. A subsequent transition to the NW geometry is observed, driven by the anisotropy of surface energies. The third part of this work covers the growth of (In,Ga)N/GaN NW heterostructures. GaN NWs with two stacked (In,Ga)N insertions are grown by MBE. The chemical composition is assessed by combining synchrotron-based HRXRD and a geometrical phase analysis of HRTEM micrographs. The structural analysis reveals that the (In,Ga)N insertions are embedded in the GaN matrix and that no plastic relaxation happens. The In content is shown to vary within a single insertion: The top region is more In rich due to In segretation during growth.

Повний текст джерелаThe present thesis presents a first comprehensive growth investigation and first quantitative growth models of group-III and IV oxides synthesized by oxygen plasma-assisted molecular beam epitaxy (MBE). The developed models include kinetic and thermodynamic effects. The obtained findings are generally valid for fundamental growth processes in other growth techniques, such as pulsed laser deposition and metal-organic vapor phase-epitaxy. The growth rates and desorption rates are measured in-situ by laser reflectometry and quadrupole mass spectrometry (QMS), respectively. The binary transparent semiconducting oxides Ga2O3, In2O3, and SnO2 are investigated. It is known that the growth of group-III and IV oxides is fundamentally different as compared to other semiconductor compounds and due to the existence of suboxides. It is found that the growth rate of the binary oxides investigated is flux-stoichiometrically and thermally limited by the formation and desorption of their respective suboxide. These suboxides are identified as Ga2O for Ga2O3, In2O for In2O3, and SnO for SnO2. A suboxide is a lower oxidation state, and it is shown, that the investigated oxides grow via a two-step oxidation process. That means, all metal oxidizes to the suboxide, and the suboxide can be further oxidized to the thermodynamic stable solid metal-oxide. This two-step oxidation process is the basis for the development of a first quantitative semi-empirical MBE growth model which predicts and explains the measured growth rates and desorption rates, for binary oxides possessing suboxides. The kinetics and thermodynamics of the ternary oxide system (InxGa1−x)2O3, grown by MBE, is investigated. The average In and Ga incorporation rates into a macroscopic volume of (InxGa1−x)2O3 are measured ex-situ by energy dispersive X-ray spectroscopy. These incorporation rates are systematically analyzed and explained in the framework of kinetic and thermodynamic limitations. It is shown that Ga thermodynamically inhibits the incorporation of In into (InxGa1−x)2O3 due to its stronger Ga–O bonds. In this context, a new catalytic-surfactant effect of In on the formation of Ga2O3 is found. As a consequence of this catalytic-surfactant effect the metastable hexagonal Ga2O3 with very high crystal quality is formed. A thermodynamically induced kinetic growth model for (InxGa1−x)2O3 MBE is developed. It predicts all macroscopic metal incorporation rates and desorption rates. Possible (InxGa1−x)2O3 phases grown by MBE are investigated by X-ray crystallography. By means of X-ray diffraction analysis, a first macroscopic approach to determine the microscopic In concentration X in possible (InXGa1−X)2O3 phases is derived. The solubility limits of In and Ga in monoclinic and cubic (InXGa1−X)2O3 phases, respectively, are identified.

Повний текст джерелаThe aim of this PhD thesis is to give a partial answer to the finiteness problem for R-isomorphism classes of real forms of any smooth projective complex rational surface X, i.e. for the isomorphism classes of R-schemes whose complexification is isomorphic to X. We study this problem in terms of real structures (or antiholomorphic involutions, which generalize complex conjugation) on X: the advantage of this approach is that it helps us rephrasing our problem with automorphism groups of rational surfaces, via Galois cohomology. Thanks to recent results on these automorphism groups, using hyperbolic geometry and, to a lesser extent, holomorphic dynamics and metric geometry, we prove several finiteness results which go further than Del Pezzo surfaces and can apply to some rational surfaces with large automorphism groups
