Hipertensão arterial de difícil controle em pacientes com doença renal progressiva e diabetes mellitus

Pacientes com doenca renal progressiva e diabetes mellitus apresentam geralmente hipertensao arterial grave e de dificil controle que piora ainda mais seu prognostico renal e cardiovascular. As possiveis causas da dificuldade do controle da pressao arterial sao hipervolemia, aumento da rigidez arterial, disfuncao endotelial, estenose de arteria renal associada e regime terapeutico inadequado. O reconhecimento dessas condicoes e a abordagem medicamentosa mais adequada podem determinar o alcance das metas pressoricas relacionadas a menor risco para os pacientes. Patients with progressive renal disease and diabetes frequently exhibit severe and difficult-to-control arterial hypertension that worse even more their cardiovascular and renal prognosis. Possible causes for the un controlled blood pressure include volume excess, increased arterial stiffness, endothelial dysfunction, associated renal artery stenosis and inadequate therapeutic regimen. The acknowledgement of these conditions and the adoptionof a more effective antihypertensive treatment can help to reach pressures goals related to a lower risk for thepatient.
Tratamento Endoscópico do Enfisema: uma Atualização Bronchoscopic Treatment of Emphysema: an Update

The objective of this review is to present an update on endoscopic alternatives for the treatment of emphysema. One-way endobronchial valves continue to be the only devices approved for clinical use in the treatment of emphysema in South America. The use of the Zephyr® endobronchial valve is currently the most widely studied bronchoscopic method for treatment of emphysema and has been approved for clinical use in several countries in Europe, Asia, and South America. Another valve, the IBV® valve, has been approved for use in the treatment of persistent air leaks in the United States. In addition to clinical features, the criteria most often analyzed for indicating endoscopic treatment are dynamic hyperinflation, heterogeneity, and collateral ventilation, especially the passage of air through the interlobar fissures. Currently, there is software capable of accurately measuring heterogeneity and fissure integrity. The results obtained in various case series and certain randomized trials have shed new light on the pathophysiology of emphysema. However, additional randomized trials using the knowledge gained thus far are warranted in order to further evaluate this procedure.
The hydrodynamic evolution of the gas content in the dSph galaxy Ursa Minor induced by the feedback from types Ia and II supernovae

Abstract Dwarf spheroidal galaxies of the Local Group share a similar characteristic nowadays: a low amount of gas in their interiors. In this work, we present results from a three-dimensional hydrodynamical simulation of the gas inside an object with similar characteristics of the Ursa Minor galaxy. We evolved the initial gas distribution over 3 Gyr, considering the effects of the types Ia and II supernovae. The instantaneous supernovae rates were derived from a chemical evolution model applied to spectroscopic data of the Ursa Minor galaxy. Our simulation shows that the amount of gas that is lost varies with time and galactocentric radius. The highest gas-loss rates occurred during the first 600 Myr of evolution. Our results also indicate that types Ia and II supernovae must be essential drivers of the gas loss in Ursa Minor galaxy (and probably in other similar dwarf galaxies).
Construction of asymmetric orthogonal arrays of high strength by juxtaposition

Abstract In this paper, we propose a juxtaposition method from one column to multi-column to construct asymmetric orthogonal arrays with high strength, which is a generalization of one column juxtaposition constructing asymmetric orthogonal arrays with strength 2. Five main theoretical results for the juxtaposition method are given. Many asymmetric orthogonal arrays of strength 3 and 4 are constructed by the juxtaposition method, including some new tight asymmetric orthogonal arrays of strength 3.
Convective Transition Statistics over Tropical Oceans for Climate Model Diagnostics: GCM Evaluation

To assess deep convective parameterizations in a variety of GCMs and examine the fast-time-scale convective transition, a set of statistics characterizing the pickup of precipitation as a function of column water vapor (CWV), PDFs and joint PDFs of CWV and precipitation, and the dependence of the moisture–precipitation relation on tropospheric temperature is evaluated using the hourly output of two versions of the GFDL Atmospheric Model, version 4 (AM4), NCAR CAM5 and superparameterized CAM (SPCAM). The 6-hourly output from the MJO Task Force (MJOTF)/GEWEX Atmospheric System Study (GASS) project is also analyzed. Contrasting statistics produced from individual models that primarily differ in representations of moist convection suggest that convective transition statistics can substantially distinguish differences in convective representation and its interaction with the large-scale flow, while models that differ only in spatial–temporal resolution, microphysics, or ocean–atmosphere coupling result in similar statistics. Most of the models simulate some version of the observed sharp increase in precipitation as CWV exceeds a critical value, as well as that convective onset occurs at higher CWV but at lower column RH as temperature increases. While some models quantitatively capture these observed features and associated probability distributions, considerable intermodel spread and departures from observations in various aspects of the precipitation–CWV relationship are noted. For instance, in many of the models, the transition from the low-CWV, nonprecipitating regime to the moist regime for CWV around and above critical is less abrupt than in observations. Additionally, some models overproduce drizzle at low CWV, and some require CWV higher than observed for strong precipitation. For many of the models, it is particularly challenging to simulate the probability distributions of CWV at high temperature.
Paliperidone으로 교체한 조현병 환자에서 8주 후 Metabolic Parameter와 Positive and Negative Syndrome Scale (PANSS) 점수의 변화

【Objectives : The purpose of this study was to examine the changes in metabolic parameters and Positive and Negative Syndrome Scale (PANSS) scores of patients previously treated with atypical antipsychotic drugs other than paliperidone, after 8 weeks of treatment with paliperidone. Methods : Changes in body weight, body mass index, leptin, lipid levels, fasting glucose, and PANSS scores of patients who switched from other atypical antipsychotic drugs to paliperidone were measured after 8 weeks of treatment with paliperidone. We compared these results with those of patients who had not been treated with antipsychotic drugs for at least 2 weeks prior to treatment with paliperidone (antipsychotic drug-free patients). Results : The antipsychotic drug-free group (n = 9) did not show significant changes in metabolic parameters, but showed a significant improvement in total and subscale scores of PANSS. In the group that switched from other atypical antipsychotic drugs to paliperidone (n = 13), body weight, body mass index and fasting glucose level significantly increased, while total and subscale scores of PANSS significantly improved. Conclusions : Paliperidone treatment will benefit patients with schizophrenia who have been antipsychotic drug-free or who have had difficulty with other atypical antipsychotic drugs, with regard to their psychopathological state. However, if patients have been treated with other atypical antipsychotic drugs before switching to paliperidone, they could gain body weight or their fasting glucose level could increase over a short period because of a change in receptor number and sensitivity caused by the previously prescribed antipsychotic drugs, and hence, paliperidone should be prescribed with caution for these patients. 】
Almost finiteness of groupoid actions and Z-stability of C*-algebras associated to tilings

The property of almost finiteness was first introduced by Matui for locally compact Hausdorff totally disconnected etale groupoids with compact unit spaces, and has since been extended by Suzuki to drop the assumption of being totally disconnected. A property of the same name has been defined by Kerr for free actions of discrete groups on compact metric spaces. In this setting, Kerr shows that almost finiteness has direct relevance to the classification programme for simple, separable, unital, nuclear, infinite dimensional C*-algebras, as it implies that the associated crossed product is Z-stable. The motivating example for this thesis comes from the theory of aperiodic tilings. A tiling is a covering of Euclidean space by a collection of sets (called tiles) which overlap only on their boundaries. A tiling is called aperiodic if it does not contain arbitrarily large periodic patterns. Such tilings find physical applications, acting as models for quasicrystals. One may associate a groupoid to certain aperiodic tilings, and the C*-algebras of such groupoids encode information about physical observables in quasicrystalline molecules. In this thesis, we generalise Kerr's notion of almost finiteness of group actions to allow for actions of groupoids. We show that the canonical action of the groupoid associated to any aperiodic, repetitive tiling with finite local complexity on its unit space is almost finite, and we use this to show that the C*-algebra of the tiling is Z-stable. We develop a groupoid version of the Ornstein-Weiss quasitiling machinery, which we use to prove our Z-stability result. Finally, we give a direct proof that tiling C*-algebras are quasidiagonal, which eases the route to classification in the case that the algebra has unique trace.
Rovibrational Spectral Analysis of CO3 and C2O3: Potential Sources for O2 Observed in Comet 67P/Churyumov–Gerasimenko

The recent ROSETTA mission to comet 67P/Churyumov–Gerasimenko detected surprisingly high levels of molecular oxygen (O2; hypervolatile species) in the coma. Current models predict that considerable levels of other hypervolatiles (such as molecular nitrogen, N2, methane, CH4, and Argon) should be found at similar levels, whereas they are more depleted. One explanation explored here is that larger (less volatile) parent molecules may have been formed during radiolysis of cometary ices and, upon sublimation, are subsequently broken down within the coma into smaller, more volatile fragments. In support of this hypothesis, this work employs reliable quantum chemical techniques to provide the spectral data necessary for the detection of two candidate precursor “parent” molecules, cyclic carbon trioxide (c-CO3), and cyclic dicarbon trioxide (c-C2O3). Benchmark computations performed for gas-phase CO2 give vibrational frequencies to within 1.5 cm−1 or better for the three fundamentals. Both c-CO3 and c-C2O3 have strong infrared features in the 4.5–5.5 μm (1800–2200 cm−1) range and other notable infrared features closer to 1100 cm−1 (9.10 μm). These molecules are both rotationally active, unlike CO2, and are therefore potentially observable and present new targets for radio telescope observations. Due to the stronger dipole moment, c-CO3 should be more easily detectable than the nearly non-polar c-C2O3. These data may help observations of these molecules and can provide insights as to how radiation-driven derivatization of CO/CO2 precursors could contribute to the generation of higher-mass parent species that subsequently degrade to produce more volatile species, such as O2, observed in cometary comae.
Hybrid Quantum Salp Swarm Algorithm for Contrast Enhancement of Natural Images

: This paper proposes a new hybrid approach based on quantum computing and SSA to boost the performance of SSA through finding the optimal trade-off between exploitation and exploration. QSSA relies on embedding the integration of the quantum operators and interference in the optimization process of SSA and the quantum representation of the search space. QSSA is tested on 29 global benchmark functions of CEC2017 and 8 benchmark images. The simulation results showed that employing the principles of quantum can significantly boost the performance of SSA. The performance of QSSA is compared with SSA and other recent and well-known optimization algorithms. The results on CEC2017 demonstrated the capability of QSSA to find the global optima for most of unimodal and multimodal benchmark functions, especially with complex search space. Moreover, the results revealed that the proposed image enhancement based QSSA is robust and can distinctly enhance the contrast of the color images.
Multilayer Codes for Synchronization From Deletions and Insertions

Consider two remote nodes (encoder and decoder), each with a binary sequence. The encoder’s sequence X differs from the decoder’s sequence Y by a small number of edits (deletions and insertions). The goal is to construct a message M, to be sent via a one-way error free link, such that the decoder can reconstruct X using M and Y. In this paper, we devise a coding scheme for this one-way synchronization model. The scheme is based on multiple layers of Varshamov-Tenengolts (VT) codes combined with off-the-shelf linear error-correcting codes, and uses a list decoder. We bound the expected list size of the decoder under certain assumptions, and validate its performance via numerical simulations. We also consider an alternative decoder that uses only the constraints from the VT codes (i.e., does not require a linear code), and has a smaller redundancy at the expense of a slightly larger average list size.

IMPROVING THE SENSITIVITY OF ADVANCED LIGO THROUGH DETECTOR CHARACTERIZATION

This dissertation focuses on the impact of detector characterization work on searches for gravitational waves from compact binary coalescences (CBCs) in Advanced LIGO’s second observing run (O2). This observing run started on November 30, 2016, and lasted until August 25, 2017, and resulted in the identification of 8 unambiguous gravitational-wave signals, including the first observation of a binary neutron star merger. The role of detector characterization is to leverage knowledge of both the interferometers and the data in order to improve aLIGO’s ability to observe gravitational-waves. I focus on the construction of the O2 noise subtracted data set that was searched as a part of the LIGO-Virgo Collaboration’s first gravitational-wave catalog, GWTC1. This data set was processed with a noise subtraction pipeline to remove the excess noise identified at each interferometer that resulted in a 30% improvement in the sensitive volume that aLIGO was able to probe. Equally important to the finalized data set is the inclusion of data quality vetoes that indicate periods of instrumental artifacts. I also examine how these instrumental artifacts can mimic gravitational-wave waveforms and reduce the sensitivity of searches for CBC signals, with particular emphasis on the PyCBC pipeline. Understanding this connection is one of the key ways that gravitational waves are differentiated from instrumental artifacts. Finally, I detail the final results presented in the GWTC-1 catalog from a detector characterization perspective, and discuss how the efforts highlighted in this dissertation allowed for the detection of new gravitational-wave events and improved analyses of previously identified events.

Model-Free Optimal Output Regulation for Linear Discrete-Time Lossy Networked Control Systems

In this article, a new model-free approach is proposed to solve the output regulation problem for networked control systems, where the system state can be lost in the feedback process. The goal of the output regulation is to design a control law that can make the system achieve asymptotic stability of the tracking error while maintaining the stability of the closed-loop system. The solvability of the output regulation problem depends on the solvability of a set of matrix equations called the regulator equations. First, a restructured dynamic system is established by using the Smith predictor; then, an off-policy algorithm based on reinforcement learning is developed to calculate the feedback gain using only the measured data when dropout occurs. Based on the solution to the feedback gain, a model-free solution is provided for solving the forward gain using the regulator equations. The simulation results demonstrate the effectiveness of the proposed approach for discrete-time networked systems with unknown dynamics and dropout.
Miniaturized Triple-Band Highly Transparent Antenna

In this article, a novel on-glass antenna which is transparent, miniaturized, and multiband is presented. First, the antenna achieves more than 80% transparency. This is realized by removing as much as possible the metal pattern, without compromising the operational electric current flow. Second, the antenna is electrically small, $0.13\lambda \times 0.19\lambda $ at 0.95 GHz. This is realized by choosing a proper topology for the remaining metal pattern. Third, the antenna is triple band, covering the ranges 0.88–1.03 GHz, 1.47–2.74 GHz, and 3.32–5.97 GHz. The radiation is omnidirectional in all bands, which is suitable for GSM900/1800, 3G, 4G, 5G (2.55–2.65 GHz), WLAN (2.4/5.2/5.8 GHz), and WiMAX (2.5/5.5 GHz). The maximum gain in the three bands is equal to −0.18, 3.66, and 4.35 dBi with corresponding radiation efficiencies of 66%, 87%, and 88%. A prototype is made by first printing a metallic circuit on a thin FR-4 substrate and then gluing it on a glass substrate. The measurement results are in good agreement with simulations.
Dielectric-Loaded Ultrawideband RCS Reduction Structures

A novel yet geometrically simple radar cross section suppression structure is proposed. Unlike designs fostered in prior works, which contain multiple elevated metal layers, the proposed configuration is only accomplished with a dielectric superstrate. Dielectric loadings of different properties such as permittivity, loss tangent, and thickness are applied to form phase cancellation structures. Contrary to structures based on resonant elements, the proposed constructs are electrically large and are made of homogeneous loadings. A high-frequency method is developed to explain how the ultrawideband backscattering suppressing feature is accomplished. Since it assesses structure reflection properties in a timely fashion with the results comparable to the ones acquired from full-wavelength tools, design optimization can be carried out via grid search. One design exhibits a 4.09:1 bandwidth ratio of 10 dB backscattering reduction for normal incidence, while another achieves a 70% bandwidth of 20 dB reduction. Angular domain performances were also researched. By adopting either the conventional checkerboard pattern or our previously developed random patch pattern, strong backscattering lobes can be avoided near the boresight region. Performance verification via measurements on prototypes is also provided.
Variational eigenerosion for rate‐dependent plasticity in concrete modeling at small strain

In the context of eigenfracture scheme, the work at hand introduces a variational eigenerosion approach for inelastic materials. The theory seizes situations where the material accumulates large amounts of plastic deformations. For these cases, the surface energy entering the energy balance equation is rescaled to favor fracture, thus energy minimization delivers automatically the crack‐tracking solution also for inelastic cases. The minimization approach is sound and preserves the mathematical properties necessary for the Γ‐limit proof, thus the existence of (local) minimizers is guaranteed by the Γ‐convergence theory. Although it is not possible to demonstrate that the obtained minimizers are global, satisfactory results are obtained with the local minimizers provided by the method. Furthermore, with the goal of addressing the constitutive behavior of concrete, a Drucker‐Prager viscoplastic consistency model is introduced in the microplane setting. The model delivers a rate‐dependent three‐surface smooth yield function that requires hardening and hardening‐rate parameters. The independent evolution of viscoplasticity in different microplanes induces anisotropy in the mechanical response. The sound performance of the model is illustrated via numerical examples for both rate‐independent and rate‐dependent plasticity.
Fractal microsttrip patch antennas with fractal perimeter and self-affine properties

La necesidad de satisfacer las futuras demandas impuestas por los sistemas de comunicacion sin hilos implica que la tecnologia en el campo de las antenas tenga que evolucionar, ya que es muy dificil aportar una solucion con la tecnologia clasica de antenas. El propio de esta tesis es introducir una nueva tecnologia en el diseno de las antenas microstrip, que permita aportar soluciones a la hora de disenar antenas multibanda, antenas de tamano reducido y antenas de elevada directividad para los sistemas de comunicacion sin hilos presentes y futuros. Dicha tecnologia consiste en emplear la geometria fractal para disenar antenas microstrip multibanda, miniatura y de elevada directividad. En referencia al comportamiento multibanda, se han estudiado antenas microstrip en las que su geometria esta definida por el fractal del triangulo de sierpinski (parche de Sierpinski) y la alformbra de Sierpinski (parche de la Alfombra de Sierpinski). Otra de las propiedades que presentan la antenas fractales microstrip es que su frecuencia de resonancia es menor que la frecuencia de resonancia correspondiente a su version Euclidea. La reduccion de frecuencia se ha estudiado para los fractales de superficie. Esta tesis tambien expone que la geometria fractal es muy valiosa de cara al diseno de antenas microstrip con elevada directividad. Esta propiedad es consecuencia del efecto de localizacion que presentan los resonadores fractales con condiciones de contorno tipo Neumann. El efecto de localizacion se ha estudiado en los fractales de masa y superficie.
Management of long bone fractures in cattle

Fractures are encountered on a regular basis in large animal practice and managing them poses a challenge in the field. Cattle are excellent orthopaedic patients: they have great bone healing properties, most tolerate limb immobilisation well and they rarely suffer from contralateral limb disorders. However, the decision between treatment and euthanasia depends on the economic or genetic value of the animal, the cost of the treatment and the prognosis associated with the particular fracture. Treatment choices vary between stall rest, external coaptation, external fixation and open reduction with internal fixation, depending on the type of fracture and the bone involved. This article describes the different treatment options for common fractures encountered in cattle.
