description: In order to better understand the variation mechanism of ozone abundance in the middle atmosphere, the simultaneous monitoring of ozone and other minor molecular species, which are related to ozone depletion, is the most fundamental and critical method. A waveguide-type multiplexer was developed for the expansion of the observation frequency range of a millimeter-wave spectroradiometer, for the simultaneous observation of multiple molecular spectral lines. The proposed multiplexer contains a cascaded four-stage sideband-separating filter circuit. The waveguide circuit was designed based on electromagnetic analysis, and the pass frequency bands of Stages 1-4 were 243-251 GHz, 227-235 GHz, 197-205 GHz, and 181-189 GHz. The insertion and return losses of the multiplexer were measured using vector network analyzers, each observation band was well-defined, and the bandwidths were appropriately specified. Moreover, the receiver noise temperature and the image rejection ratio (IRR) using the superconducting mixer at 4 K were measured. As a result, the increase in receiver noise due to the multiplexer compared with that of only the mixer can be attributed to the transmission loss of the waveguide circuit in the multiplexer. The IRRs were higher than 25 dB at the center of each observation band. This indicates that a high and stable IRR performance can be achieved by the waveguide-type multiplexer for the separation of sideband signals.

description: In a system where a boson (e.g, a phonon) of finite frequency $ω_0$ is coupled to electrons, two phenomena occur as the coupling is increased: electron pairing and polarization of the boson field. Within a path integral formalism and a Dynamical Mean-Field approach, we introduce {\it ad hoc} distribution function which allow us to pinpoint the two effects. When $ω_0$ is smaller than the bandwidth $D$, pairing and polarization occur for fairly similar couplings for all considered temperatures. When $ω_0 > D$, the two phenomena tend to coincide only for $T \gg ω_0$, but are no longer tied for low temperatures so that a state of paired particles without finite polarization is stabilized.

description: O crescimento do setor de serviços tem evidenciado a importância de as empresas dedicarem mais atenção à qualidade com que seus serviços são prestados. Dentre todos os aspectos considerados, um dos mais relevantes, porém muitas vezes deixado para segundo plano, refere-se à qualidade que deve estar presente nos serviços prestados internamente aos próprios funcionários das empresas, ou seja, na relação cliente-fornecedor interno. Neste caso, consideraremos a relação entre os setores de operações de serviços de retaguarda (BACK ROOM) e a frente de trabalho (FRONT OFFICE). Para avaliar a qualidade no atendimento em uma empresa, utilizaremos o Ciclo PDCA e o Diagrama de Pareto. The growth of the section of services has been evidencing the importance of the companies dedicate more attention to the quality with that their services are rendered. Among all of the considered aspects, one of the most relevant, however a lot of times left for second plan, refers to the quality that should be present in the services rendered the own employees of the companies internally, in other words, in the relationship internal customer-supplier. In this case, we will consider the relationship among the sections of operations of rearguard services (BACK ROOM) and the work front (FRONT OFFICE). Para to evaluate the quality in the service in a company, we will use the Cycle PDCA and the Diagram of Pareto.

description: We study the steady plane shear flow of a dense assembly of frictional, inelastic disks using discrete simulation and prescribing the pressure and the shear rate. We show that, in the limit of rigid grains, the shear state is determined by a single dimensionless number, called inertial number I, which describes the ratio of inertial to pressure forces. Small values of I correspond to the quasi-static regime of soil mechanics, while large values of I correspond to the collisional regime of the kinetic theory. Those shear states are homogeneous, and become intermittent in the quasi-static regime. When I increases in the intermediate regime, we measure an approximately linear decrease of the solid fraction from the maximum packing value, and an approximately linear increase of the effective friction coefficient from the static internal friction value. From those dilatancy and friction laws, we deduce the constitutive law for dense granular flows, with a plastic Coulomb term and a viscous Bagnold term. We also show that the relative velocity fluctuations follow a scaling law as a function of I. The mechanical characteristics of the grains (restitution, friction and elasticity) have a very small influence in this intermediate regime. Then, we explain how the friction law is related to the angular distribution of contact forces, and why the local frictional forces have a small contribution to the macroscopic friction. At the end, as an example of heterogeneous stress distribution, we describe the shear localization when gravity is added.

description: Geometrical dephasing is distinct from dynamical dephasing in that it depends on the trajectory traversed, hence it reverses its sign upon flipping the direction in which the path is traced. Here we study sequences of generalized (weak) measurements that steer a system in a closed trajectory. The readout process is marked by fluctuations, giving rise to dephasing. Rather than classifying the latter as "dynamical" and "geometrical", we identify a contribution which is invariant under reversing the sequence ordering and, in analogy with geometrical dephasing, one which flips its sign upon the reversal of the winding direction, possibly resulting in partial suppression of dephasing (i.e., "coherency enhancement"). This dephasing asymmetry (under winding reversal) is a manifestation of intrinsic chirality, which weak measurements can (and generically do) possess. Furthermore, the dephasing diverges at certain protocol parameters, marking topological transitions in the measurement-induced phase factor.

description: We construct and apply to beta decays a truly neutral local quantum field that is entirely based upon momentum space Majorana spinors. We make the observation that theory with momentum space Majorana spinors of real C parities is equivalent to Dirac's theory. For imaginary C parities, the neutrino mass can drop from the single beta decay trace and reappear in 0νββ, a curious and in principle experimentally testable signature for a non-trivial impact of Majorana framework in experiments with polarized sources.

description: Diante de um mundo cada vez mais dinâmico e inundado de informações, tornase difícil para o consumidor verificar a qualidade dos alimentos e do processo pelos quais foram obtidos. Em vista disso, as organizações são pressionadas a implantarem processos de qualidade que são certificados por terceira parte, processos estes que causam impactos e geram uma série de mudanças. O objetivo deste artigo foi o de apontar os impactos que o processo de certificação Utz Kapeh causou nas pessoas, na gestão e na competitividade de duas organizações rurais produtoras de café, situadas no Sul de Minas Gerais. Para a obtenção dos dados foram utilizadas técnicas de observação não participante, análise documental e entrevistas e para a sua análise foi utilizada a análise de conteúdo. Deste estudo, extraiu-se um modelo no qual se evidenciou um maior impacto da certificação na gestão das organizações e a importância de uma rede (Cooperativa) como forma de obter um preço diferenciado pelo café certificado. Faced with a world increasingly dynamic and flooded with information, it becomes difficult for the consumer to verify the quality of the foods and the process of it production. In view of that, organizations are pressed to be certified by third party to ensure the quality of their product, service or process. These processes cause impacts and generate a series of organizational changes. The objective of this article was to verify the impacts caused by the Utz Kapeh certification in the employees, in the management and in the competitiveness of two rural coffee companies, located in the South of Minas Gerais. The techniques used to obtained the data were no participant observation, documental analysis and interviews and for data analysis was used the content analysis. Starting for this study, was extracted a model in which was evidenced the greatest impact of certification in management of the organizations and the importance of a net (Cooperative) as a form of obtaining a differentiated price by coffe certified.

description: We revisit our 2013 claim [arXiv:1303.7476] that the Universe is the result of a conspiratorial plot, and find that it cannot be trusted, because even the belief in this conspiracy likely results from a conspiracy. On the basis of mathematical beauty, the final results of the Planck mission, the exploration of the dark sector by means of occult rituals and symbols, and a powerful new philosophical approach to physics, we demonstrate here that not only the existence of our Universe but the whole concept of reality has to be rejected as obsolete and generally misleading. By introducing the new concept of the "anthropogenic principle", we eventually illuminate the darkest corners of the conspiracy behind the conspiracy and briefly discuss some important implications regarding the survival of wo*mankind.

description: Após a abertura comercial em 1998, grandes mudanças ocorreram no comércio exterior nacional devido sucessivos choques cambiais aos quais a economia foi exposta. A literatura de referência sugere que grandes choques na taxa de câmbio induzem mudanças persistentes na relação entre a taxa de câmbio e o comércio. Este fenômeno é conhecido por histerese. Desta forma, o objetivo deste trabalho é evidenciar a existência de histerese no comércio internacional brasileiro, com interesse particular no setor agrícola. Os resultados indicaram evidências de histerese simples na taxa de câmbio e nas importações brasileiras, e de histerese fraca no setor agrícola e nas exportações. Conclui-se que a mudança de regime cambial em 1999 e a unificação cambial em 2005 promoveram efeitos de histerese, sobretudo nas importações brasileiras e no setor agrícola. After the commercial opening in 1998, significant changes in the external trade occurred due to the exchange shocks for which the economy was exposed. The reference literature suggests that significant shocks in the exchange rate induce persistent changes in the relationship between the exchange rate and the international trade. Such phenomenon is called hysteresis. In this sense, the objective of this work is to verify the existence of hysteresis in the Brazilian international trade with special interest in the agricultural sector. The results indicate existence of simple hysteresis in the exchange rate and in the Brazilian imports as well weak hysteresis in the agricultural sector and in the Brazilian exports. It is possible to conclude that the change of exchange regime in 1999 and the exchange unification in 2005 leaded effects of hysteresis specially in the Brazilian imports and in the agricultural sector.

description: Transient changes in intracellular pH (pHi) regulate normal cell behaviors, but roles for spatiotemporal pHi dynamics in single-cell behaviors remain unclear. Here, we mapped single-cell spatiotemporal pHi dynamics during mammalian cell cycle progression both with and without cell cycle synchronization. We found that single-cell pHi is dynamic throughout the cell cycle: pHi decreases at G1/S, increases in mid-S, decreases at late S, increases at G2/M and rapidly decreases during mitosis. Importantly, although pHi is highly dynamic in dividing cells, non-dividing cells have attenuated pHi dynamics. Using two independent pHi manipulation methods, we found that low pHi inhibits completion of S phase whereas high pHi promotes both S/G2 and G2/M transitions. Our data also suggest that low pHi cues G1 exit, with decreased pHi shortening G1 and increased pHi elongating G1. Furthermore, dynamic pHi is required for S phase timing, as high pHi elongates S phase and low pHi inhibits S/G2 transition. This work reveals that spatiotemporal pHi dynamics are necessary for cell cycle progression at multiple phase transitions in single human cells.

description: Coherent steering of a quantum state, induced by a sequence of weak measurements, has become an active area of theoretical and experimental study. For a closed steered trajectory, the underlying phase factors involve both geometrical and dynamical terms. Furthermore, considering the reversal of the order of the measurement sequence, such a phase comprises a symmetric and an antisymmetric term. Superseding common wisdom, we show that the symmetric and the antisymmetric components do not correspond to the dynamical and geometrical parts respectively. Addressing a broad class of measurement protocols, we further investigate the dependence of the induced phases on the measurement parameters (e.g., the measurement strength). We find transitions between different topologically distinct sectors, defined by integer-valued winding numbers, and show that the transitions are accompanied by diverging dephasing. We propose experimental protocols to observe these effects.

description: We consider the phenomenology of the 511 keV emission in the Galactic bulge, as recently observed by INTEGRAL, and propose a model is which the positrons are produced by gamma-ray bursts (GRB) associated with mini starbursts in the central molecular zone (CMZ). We show that the positrons can easily diffuse across the bulge on timescales of about 10^7 yr, and that their injection rate by GRBs is compatible with the observed fluxes if the mean time between two GRBs in the bulge is about 8 10^4 yr x E_GRB_51. We also explain the low disk-to-bulge emission ratio by noting that positrons from GRBs in the Galactic disk should annihilate on timescales of < 10^4 yr in the dense shell of the underlying supernova remnant, after the radiative transition, while the remnants of GRBs occurring in the hot, low-density medium produced by recurrent starbursts in the CMZ become subsonic before they can form a radiative shell, allowing the positrons to escape and fill the whole Galactic bulge. If the mean time between GRBs is smaller than 10^4 E_51 yr, INTEGRAL should be able to detect the (localized) 511 keV emission associated with one or a few GRB explosions in the disk.

description: The dynamics and momentum budget of the quasi-biennial oscillation (QBO) are examined in the ERA5 reanalysis and compared with those in ERA-I. Because of ERA5's higher spatial resolution it is capable of resolving a broader spectrum of atmospheric waves and allows for a better representation of the wave-mean flow interactions, both of which are of crucial importance for QBO studies. It is shown that the QBO-induced mean meridional circulation, which is mainly confined to the winter hemisphere, is strong enough to interrupt the tropical upwelling during the descent of the westerly shear zones. Since the momentum advection tends to damp the QBO, the wave forcing is responsible for both the downward propagation and for the maintenance of the QBO. It is shown that half the required wave forcing is provided by resolved waves during the descent of both westerly and easterly regimes. Planetary-scale waves account for most of the resolved wave forcing of the descent of westerly shear zones and small-scale gravity (SSG) waves with wavelengths shorter than 2000 km account for the remainder. SSG waves account for most of the resolved forcing of the descent of the easterly shear zones. The representation of the mean fields in the QBO is very similar in ERA5 and ERA-I but the resolved wave forcing is shown to be substantially stronger in ERA5. The contributions of the various equatorially-trapped wave modes to the QBO forcing are documented in Part II.

description: We report the local magnetic response of an electron-doped cuprate superconductor, Pr$_{0.89}$LaCe$_{0.11}$CuO$_{4}$ ($T_c\simeq26$ K), studied by muon spin rotation (\msr) over a field range from 200 Oe to 50 kOe. In the paramagnetic state, the muon Knight shift along the crystal c-axis ($K_μ^z$) is proportional to the in-plane susceptibility $χ_{ab}$. More surprisingly, $K_μ^z$ is strongly enhanced by the occurrence of superconductivity (below $\sim$40 kOe), changing its sign from positive to negative around $\sim1$ kOe with increasing field. This finding can be understood by considering the weak polarization of Pr ions due to superexchange interaction with the antiferromagnetic Cu sublattice, which coexists with superconductivity.

description: We study single-particle excitations in the Mott insulator phase of a Bose gas in an optical lattice. The characteristic feature of the single-particle spectrum in the Mott insulator phase is the existence of an energy gap between the particle and hole excitations. We show that this energy gap can be directly probed by an output coupling experiment. We apply the general expression for the output current derived by Luxat and Griffin, which is given in terms of the single-particle Green's functions of a trapped Bose gas, to the Mott insulator phase using the Bose-Hubbard model. We find that the energy spectrum of the momentum-resolved output current exhibits two characteristic peaks corresponding to the particle and hole excitations, and thus it can be used to detect the transition point from the Mott insulator to superfluid phase where the energy gap disappears.

description: In earlier work, N=(1,1) super Yang--Mills theory in two dimensions was found to have several interesting properties, though these properties could not be investigated in any detail. In this paper we analyze two of these properties. First, we investigate the spectrum of the theory. We calculate the masses of the low-lying states using the supersymmetric discrete light-cone (SDLCQ) approximation and obtain their continuum values. The spectrum exhibits an interesting distribution of masses, which we discuss along with a toy model for this pattern. We also discuss how the average number of partons grows in the bound states. Second, we determine the number of fermions and bosons in the N=(1,1) and N=(2,2) theories in each symmetry sector as a function of the resolution. Our finding that the numbers of fermions and bosons in each sector are the same is part of the answer to the question of why the SDLCQ approximation exactly preserves supersymmetry.

description: Self-selection into healthcare options on the basis of severity likely biases estimates of the effects of healthcare choice on health outcomes. Using an instrumental variables strategy which exploits exogenous variation in the cost of formal-sector care, we show that using such care to treat acute sickness decreases the incidence of fever and malaria in young children in Tanzania. Compared to the instrumental variables estimates, ordinary least squares estimates significantly understate the effects of formal-sector healthcare use on health outcomes. Improved information and more timely treatment, rather than greater access to medicines, seem to be the primary mechanisms for this effect.
Searching for binary and millisecond pulsars : a high-latitude drift-scan survey
Creators: name: Kasian, Laura Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: We performed a drift-scan pulsar survey using the Green Bank Telescope (GBT) in West Virginia, USA. The survey is among the most sensitive ever undertaken in the Northern sky, and was collected with the Berkeley-Caltech Pulsar Machine filterbank. It was performed at low frequencies (400, 600, and 800 MHz) and mostly high Galactic latitudes with the aim of detecting new binary and millisecond pulsars. Population models of-pulsars have shown that young pulsars tend to be concentrated in the Galactic plane, while binary and millisecond pulsars appear to have a more isotropic distribution on the sky. Searches at high Galactic latitudes are therefore required in order to discover new binary and millisecond pulsars, and to better understand the distinct population of millisecond (recycled) pulsars. The data from the survey were reduced mainly using the sigproc pulsar signal processing software package. As of the writing of this thesis, ~ 73% of the data have been searched for periodicities. Each pulsar candidate is given a classification based on how closely it resembles a pulsar (Class 1 = probably a pulsar; Class 4 = most likely not a pulsar) . We were successful in re-detecting 4 previously-known pulsars, and we obtained lists of Class-1 and Class-2 candidates. We will confirm these candidates through follow-up observations with the GBT in December 2005. We detected fewer convincing Class 1 candidates than expected, which we attribute to a recently-discovered problem in the sigproc software and persistent radiofrequency interference (RFI) in the data, particularly at 600 MHz. We have corrected the software problem, which has resulted in the discovery our first Class-1 pulsar candidates. We expect that a reanalysis of processed scans and a first analysis of the remaining ~ 27% of data will yield a significantly higher number of promising candidates.

description: We estimate the effects of higher quality healthcare usage on health, labor supply and schooling outcomes for sick individuals in Tanzania. Using exogenous variation in the cost of formal sector healthcare to predict treatment choice, we show that using better quality care improves health outcomes and changes the allocation of time amongst productive activities. In particular, sick adults who receive better quality care reallocate time from non-farm to farm labor, leaving total labor hours unchanged. Among sick children, school attendance significantly increases as a result of receiving higher quality healthcare, but labor allocations are unaffected. We interpret these results as evidence that healthcare has heterogeneous effects on marginal productivity across productive activities and household members.

description: Numerical investigations on non-analytic quantum kicked systems are presented. A new type of localization - power-law localization is found to be universal in the nonanalytic systems. With increasing the perturbation strength, a transition from perturbative localization to pseudo-integrable system, to dynamical localization and to complete extension is clearly demonstrated. The dependence of the localization length on perturbation is given in different parameter regimes.

description: Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the inevitable dissipation of magnons or spin waves in magnetic systems. Here we demonstrate non-Hermitian coherent coupling of two distant nanomagnets by fast spin waves with sub-50 nm wavelengths. Magnons in two nanomagnets are unidirectionally phase-locked with phase shifts controlled by magnon spin torque and spin-wave propagation. Our results are attractive for analog neuromorphic computing that requires unidirectional information transmission.

description: It is likely that one or more gamma-ray bursts within our galaxy have strongly irradiated the Earth in the last Gy. This produces significant atmospheric ionization and dissociation, resulting in ozone depletion and DNA-damaging ultraviolet solar flux reaching the surface for up to a decade. Here we show the first detailed computation of two other significant effects. Visible opacity of NO2 is sufficient to reduce solar energy at the surface up to a few percent, with the greatest effect at the poles, which may be sufficient to initiate glaciation. Rainout of dilute nitric acid is could have been important for a burst nearer than our conservative nearest burst. These results support the hypothesis that the characteristics of the late Ordovician mass extinction are consistent with GRB initiation.

description: Models of the agricultural household have traditionally relied on assumptions regarding the complementarity or substitutability of family labor inputs. We show how data on time allocations, health shocks and corresponding treatment choices can be used to test these assumptions. Data from Tanzania provide evidence that complementarities exist and can explain the pattern of labor supply adjustments across household members and productive activities following acute sickness. In particular, we find that sick and healthy household members both shift labor away from self-employment and into farming when the sick recover more quickly. Infra-marginal adjustments within farming activity types provide further evidence of farm-specific complementarities.

description: Political coalition formation games can describe the formation and dissolution of nations, as well as the creation of coalition governments, the establishment of political parties, and other similar phenomena. These games have been studied from a theoretical perspective, but the resulting models have not been used extensively in empirical work. This paper presents a method of estimating political coalition formation models with many-player coalitions, and then illustrates this method by estimating structural coefficients that describe the behaviour of municipalities during a recent set of municipal mergers in Japan. The method enables counterfactual analysis, which in the Japanese case shows that the national government could increase welfare via a counter-intuitive policy involving transfers to richer municipalities conditional on their participation in a merger.
