Abstract:
The scintillation response of Lu1.8Y0.2SiO5:Ce (LYSO:Ce) and LaCl3:Ce scintillators were compared under g-ray excitation using photomultiplier tube (PMT) readout. For 662 keV g-rays (137Cs source), energy resolution of 4.5±0.2% obtained for LaCl3:Ce coupled to XP5200B PMT is much better than that of 8.2±0.4% for LYSO:Ce. The non-proportionality of the light yield and energy resolution versus g-ray energy were measured and the intrinsic resolution of the crystals was calculated. Special attention was devoted to the correlation between intrinsic resolution and non-proportional response of scintillators.

Abstract:
In the present day, inorganic scintillating crystals become a main part in detection and spectroscopy of nuclear particles and high energy photons, more spectively in X/g-ray imaging. The good properties for the scintillating crystals used in these applications require high photon yield, high stopping power, good energy resolution, good light yield proportionality, and minimal afterglow. The main useful of Ce-doped Lu0.7Y0.3AlO3 (LuYAP(Ce)) are high stopping power and non-hygroscopic which are expected to be key ingredients for medical imaging. In this work, we studied the light yield non-proportionality and energy resolution of LuYAP(Ce) crystal with the energy range from 31 to 1,274.5 keV using photomultiplier tube (PMT) readout. The intrinsic resolution of the LuYAP(Ce) crystal has been determined after correcting the measured PMT resolution. The results showed that the non-proportional response of the crystals was strongly correlated with the intrinsic resolution of the crystals.

Abstract:
Even though electroweak part of the Standard Model passed decades of testing and precision measurements, there is still a space for the presence of new physics. In particular, the neutrino sector in the last years has been reaching the level of precision oscillometry. However, the current data are not able to exclude many possible extended scenarios, in which new interactions comparable with the standard ones are still possible. This work is dedicated to beyond-Standard-Model interactions of neutrino and electron called Non-Standard Interactions or shortly NSI. Analogously to standard electroweak interactions, NSI could be charged current (CC) and neutral current (NC) type. Usually, in analyses of experiments, NC and CC NSI are considered separately, and I follow this strategy in the course of this work. The global search for NSI involves almost all experimental approaches of neutrino physics and goes far beyond the scope of this work. Here, instead, I look at the problem through the prism of the large-scale liquid scintillator experiments and confine the investigation to the search for NC NSI with solar neutrinos. In addition, I review CC NSI with reactor neutrinos at medium baseline. As a contribution into upcoming JUNO experiment, I investigate liquid scintillator energy response and radiopurity, which are essential for the successful realization of solar and reactor neutrino physics programs and, therefore, for NC and CC NSI search. I analyze in detail the non-linearity and energy resolution of liquid scintillator. I develop an experimental Compton coincidence technique with High Pure Germanium gamma spectrometer, provide a conservative measurement of the Birks’ ionization quenching constant kB and discuss problems related to its measurement. Throughout the study, I also formulate the optimal characteristics of the experimental apparatus for this improvement. The ultimate goal of this investigation is separating intrinsic energy resolution, which was never yet robustly measured for liquid organic scintillators. The intrinsic energy resolution may have an impact on the energy response of the new generation large liquid scintillator detectors such as JUNO and have to be carefully investigated. Applying single photon counting technique, I perform a calibration of the PMT charge scale and set apart statistical term from the total liquid scintillator energy resolution. Remaining term significantly differs from zero, indicating the presence of additional contribution associated with the intrinsic energy resolution. As an outlook, the precise estimation of the light collection should be conducted in order to ensure that its contribution is not significant to mimic the observed intrinsic resolution effect. The analysis of the radiopurity of the liquid scintillator showed that it is close to the one demanded for reactor neutrino program and CC-NSI search. Still, an improvement of purification procedure is necessary to fulfill solar neutrino program requirements for NC NSI search. Finally, I place the limits to NC NSI parameters for electron and tau neutrino with the Phase II data of Borexino experiment. The limits are quite stringent and compatible with other experiments. The best up-to-date limit to the left electron NSI-parameter is obtained. The allowed regions could be further significantly reduced by incorporating the current result in a global analysis. Besides, the same analysis approach is used to measure the squared sine of the Weinberg angle with a precision comparable with reactor neutrino experiments and place the most robust limit on the probability of ν−ν̄ conversion in the Sun for solar neutrinos with energies Eν < 1.8 MeV. I conclude with deliberation on the applicability of solar neutrino NC NSI approach for current JUNO detector configuration.

Abstract:
Dissertação de Mestrado em Física, apresentada à Faculdade de Ciências e Tecnologia da Universidade de Coimbra.
A natureza dos neutrinos é uma das questões mais importantes na atualidade da física. A sua resposta terá um grande impacto em diferentes campos da física, como por exemplo na física de partículas, na cosmologia e na física experimental de neutrinos. Esta natureza pode ser testada através da deteção do processo de decaimento beta duplo sem emissão de neutrinos. Se este decaimento se confirmar não haverá dúvida de que os neutrinos são partículas de Majorana, em vez de partículas de Dirac, como o Modelo Padrão da Física de Partículas assume. A experiência NEXT está a desenvolver uma TPC com xénon a alta pressão e que usa o processo de eletroluminescência como meio de amplificação do sinal de ionização primária, causada pelas interações da radiação com o meio gasoso. O processo de eletroluminescência permite uma amplificação de sinal efetiva com reduzidas flutuações estatísticas quando comparadas com o processo de amplificação de sinal através de multiplicação em carga. É necessário atingir uma resolução em energia muito boa para obter uma discriminação eficiente do decaimento beta duplo sem emissão de neutrinos no xénon, tanto do fundo provocado pelas interações gama, como do próprio decaimento beta duplo com emissão de neutrinos. Este último é um mecanismo algumas ordens de grandeza mais frequente do que o ββ0ν. A capacidade de reconhecimento da topologia da ionização primária do evento ββ0ν possibilitará uma posterior distinção dos eventos ββ dos eventos resultantes das interações gama. No entanto, o xénon é um gás muito lento com elevada difusão de eletrões, sendo estes fatores uma desvantagem para a distinção acima referida. A adição de aditivos moleculares ao xénon puro terá um impacto significativo na redução da difusão da nuvem de eletrões primária e no aumento da velocidade de deriva dos eletrões na mistura. Contudo, estes aditivos causarão também uma redução do rendimento de cintilação da mistura e um aumento das flutuações estatísticas associadas à produção de eletroluminescência uma vez que o eletrão de deriva, ao colidir com uma molécula, irá perder parte da sua energia cinética para os estados vibracionais e rotacionais desta, não havendo desta forma produção de cintilação. Portanto, terá de ser feito um compromisso entre a concentração de aditivo molecular e a redução do rendimento de eletroluminescência ou o aumento das flutuações estatísticas associadas à produção de eletroluminescência, sendo este o estudo efetuado neste trabalho.

Abstract:
AbstractWe present a simple parameterization for coarse-resolution ocean models. To replace computationally expensive high-resolution ocean models, we develop a computationally cheap parameterization for coarse-resolution models based solely on the modification of the viscosity term in advection equations. It is meant to reproduce the mean quantities like pressure, velocity, or vorticity computed from a high-resolution reference solution or using observations. We test this new parameterization on a double-gyre quasi-geostrophic model in the eddy-permitting regime. Our results show that the proposed scheme improves significantly the energy statistics and the intrinsic variability on the coarse mesh. This method shall serve as a deterministic basis model for coarse-resolution stochastic parameterizations in future works.

Abstract:
Ribosomes are the sites of messenger RNA (mRNA) translation to protein, and thus are crucial to the normal functioning of all cells. These ribonucleoprotein particles are composed of a small (30S) subunit and a large (50S) subunit. The 30S subunit, in turn, is composed of a strand of RNA (16S rRNA) and 21 proteins ranging in molecular weight from 9 kD to 61 kD. Studies have demonstrated that ribosomal RNA is necessary for normal ribosome function and protein production (Dahlberg, 1989; Noller, 1991). In particular, 16S rRNA is essential for normal assembly and function of the 30S subunit, which is responsible for translation initiation (Hardestyand Kramer, 1985). Elucidating the structure of 16S rRNA could greatly aid our understanding of the molecular mechanisms for protein translation, and such basic structural information could ultimately have wide-ranging importance in fields such as pharmacology and drug design. Because of the difficulties associated with X-ray analysis of large complexes such as the ribosome (Eisenstein et al., 1991), high-resolution structural data for the 16S rRNA remain sparse. However, neutron diffraction studies have determined the relative positions of the 30S proteins (Capel et al., 1988), which, along with the reported 16S rRNA-protein interactions (Noller, 1991, Noller et al., unpublished; Brimacombe, 1991), enable low-resolution structural models—showing how the RNA associates with the protein components—to be built. Several studies have sought to take advantage of these structural data for the 308 subunit. Stern et al. have used interactive model building to produce a three-dimensional 16S rRNA structure (Stern et al., 1988). This method can produce viable models, but is hindered somewhat by subjectivity intrinsic to the process and by the nonexhaustive nature of its conformation search. Hubbard and Hearst have used distance geometry techniques to model the RNA structure, but did not incorporate neutron diffraction data on the protein positions (Hubbard and Hearst, 1991). Malhotra and Harvey have used an energy minimization technique to produce a set of possible conformations for 16S rRNA; their study, however, depends on electron microscopic studies on the molecule to provide initial information on surface topology (Malhotra, 1994).

Abstract:
The many proteins and nucleic acids encoded in the genome predominantly perform their functions as macromolecular assemblies. In fact, modern biomedical research often targets the interactions of individual molecules of these assemblies, usually by disrupting or enhancing specific contacts, to provide treatment for many different diseases. Therefore, efficient pharmaceutical design requires knowledge of how macromolecular assemblies are built and function. To achieve this goal, sensitive and quantitative tools are essential. This chapter will discuss the use of flow cytometry as a general platform for sensitive measurement and quantification of molecular assemblies. First, this chapter will introduce general methods for analysis of molecular interactions along with a comparison of flow cytometry with these methods. Second, an overview of current flow cytometry instrumentation, assay technologies, and applications in molecular assembly analysis will be given. Third, the implementation of the above approaches in molecular assembly will be discussed. Finally, potential future directions of flow cytometry in molecular assembly analysis will be explored. At present, the analysis of macromolecular assemblies is performed by a wide variety of techniques that are chosen for the target molecules under study (proteins, DNA, lipids, etc.), the type of measurement required (kinetic or equilibrium), and whether the assembly of interest needs to be studied in vivo or in vitro. This continuum of techniques can be divided into the heterogeneous assays, which require a separation step to resolve products from reactants, and homogeneous assays, which can measure interactions without a separation step. Heterogeneous assays, in general, use radioisotopes, which are not perturbing; offer excellent sensitivity; and provide accurate quantification. The products are quantified after a separation step such as gel filtration, gel electrophoresis, or centrifugation. Rapid quench methods can provide subsecond kinetic resolution; however, the added separation steps are tedious and make collection of kinetic time courses difficult, as each time point must be separated and measured individually. Furthermore, in the time it takes the separation to occur, the interaction of interest can dissociate, which is a problem specific to low-affinity assemblies. Nonetheless, by using rapid chemical quench techniques, reaction times as short as a few milliseconds can be observed. Homogenous assays can be separated into solution- or surface-based assays. Solutionbased assays measure an optical signal generated by the assembly to quantify an interaction. High component concentrations (micromolar) allow changes in intrinsic molecular properties, such as protein fluorescence or circular dichroism, to be used to study molecular assemblies. For greater sensitivity (nanomole component concentrations), resonance energy transfer or polarization assays using exogenous fluorescent labels can be used. In combination with stopped-flow spectroscopy methodologies, solution-based assays allow reactions to monitored in a continuous fashion with submillisecond dead times.

Abstract:
An interesting phenomenon associated with high-order harmonic generation is the development of an intrinsic phase variation at the atomic level between the phase of the laser field and the phase of the emitted harmonic light. We created experimental conditions where the harmonics could be thought of as emerging from a single plane rather than a 3-dimensional volume.1,2 The appearance of broad wings (carrying ~75% of the energy) in the harmonic farfield angular profiles under such conditions indicates the presence of strong intensity-dependent intrinsic phases. The diffraction of the individual harmonics which causes the wings occurs because intrinsic phases translate into radial phase variations in the laser focus according to the intensity distribution.

Abstract:
A selfconsistent framework for study of the surface electronic structure of finite superlattices has been proposed. Our emphasis is on the influence of accumulation or depletion layer on the surface states (Tamm states). We have used a modulated doping profile, including an accumulation or a depletion surface layer, in our selfconsistent calculations of potential and carrier density profile. We have found the existence of Tamm states above(depletion layer) or below(accumulation layer) the superlattice miniband. One of the Tamm states found crosses the Fermi energy in the energy gap when the depletion effect, resulting from dangling bonds, defects, impurities, etc, near the surface increases. In our case, near the top layer of the superlattice the depletion region was formed as a result of the pinning of the Fermi level below its position in intrinsic GaAs due to the midgap surface states.

Abstract:
Scattering of femtosecond optical and near infrared pulses off a low energy relativistic electron beam at 90° offers an interesting possibility to generate ultrashort pulses of x-rays. The x-ray pulses are short since the electron beam can be squeezed and focussed hard transversely, thus matching the interaction time with the femtosecond optical pulse duration. This is difficult with collinear scattering since electron beams with lengths less than a few picoseconds are hard to produce. The method has some intrinsic attractive features, e.g. simplicity of concept, directivity, tunability, etc. Experiments are under preparation in the Beam Test Facility of the Center for Beam Physics at LBL where a 30 MeV electron beam from the ALS injector linac will be scattered against a 0.8 μm, 100 mJ/pulse Terawatt femtosecond laser. Short pulse x-ray detection schemes are under development as well.

Abstract:
Several ensembles of sweeping diagnostic impulsive forces were measured in a unidirectional carbon-epoxy composite beam modified locally with a soft viscoelastic patch. The spatial uniformity of the typical ensemble of diagnostic signals is addressed by a systematic spatio-temporal coherence analysis in terms of proper orthogonal decomposition (POD) modes. All samples of spanning ensembles are strongly dominated by the same POD mode characterized by a nearly uniform spatial modulation and a sharp triangular pulse time modulation. The higher POD modes have small amounts of energy. They possess an important statistics property: their spatial modulation mean value is nearly zero with standard deviation nearly identical to the nearly uniform value of the dominant POD mode. The nearly uniform spatial distribution of the dominant POD mode is a fuzzy picture of the ideal or nominal one where the impact-generated diagnostic forces should have a time waveform independent of the site of impact. Despite this energy content deficiency, the ensemble of acceleration signals acquired at a fixed point while the beam is excited by an ensemble of sweeping diagnostic forces has very robust POD modal structure. The POD modes show in a clear manner the presence of a soft viscoelastic patch simulating mass modifications. The POD-based coherence analysis of ensembles of diagnostic forces generated in this practical problem is potentially useful for a real-time verification-inspection of the integrity of networks of embedded and surface-mounted actuators and sensors.
