Authors: Perales Cabezas Iván 
Published: October 2019

Introducción: En las últimas dos décadas al acceso pterional clásico descrito por Yasargil se le han realizado modificacionesimportantes en búsqueda de acceder a la base del cráneo, tales como el acceso transcigomático y orbitocigomático; más recientemente, accesos mínimamente invasivos, abordajes keyhole. Es así como se ha descrito el acceso minipterionalcon disección interfascial, el que ha sido combinado con técnicas de la base del cráneo, clinoidectomía anterior extradural,peeling de fosa media y petrosectomía anterior de Kawase, por el equipo de Neurocirugía Vascular y de la base del Cráneodel Instituto de Neurocirugía (INCA), a cargo del Dr. Jorge Mura, logrando resolver patologías complejas por un acceso keyhole. Este trabajo presenta una serie clínica, multicéntrica, realizada por un mismo neurocirujano, y que tiene como objetivo demostrar que el acceso minipterional simple y combinado es reproducible en otros centros, con buenos resultados clínicos. Materiales y Métodos: El autor presenta una serie clínica, de 56 pacientes, tratados en el hospital San Pablo de Coquimbo y Clínica Elqui de La Serena, entre abril de 2017 y agosto de 2018, con un seguimiento prospectivo de los resultados clínicos, los cuales fueron evaluados con la escala de Rankin modificado. Resultados: En un total de 56 casos, predominó el sexo femenino (71%), la edad media fue de 53 años y la patología aneurismática fue lo más frecuente con 45 casos, de estos el 60% fueron aneurismas rotos; el 7% correspondieron a tumores de la base del cráneo y el 12,5% a hidrocefalias no comunicantes resueltas por la apertura de la lámina terminalis. En 9 casos se combinó el acceso minipterional con clinoidectomía anterior extradural y en 3 casos se hizo un peeling de fosa media. El mayor tiempo quirúrgico estuvo asociado al acceso minipterional combinado, ya sea por patología tumoral o aneurismas paraclinoideos. Se obtuvo un resultado neurológico favorable (ERm < 3) en el 87,5% de los pacientes. Conclusión y Discusión: actualmente la evidencia ha dejado de manifiesto que el acceso minipterional tiene ventajas sobre otros accesos keyhole, principalmente por la posibilidad de poder combinarlo con técnicas de base del cráneo, pudiendo resolver patologías que antes no era posible tratar por accesos mínimamente invasivos. El acceso pterional clásico, sin embargo, sigue teniendo indicación en casos seleccionados. Por otra parte, esta serie clínica confirma que el acceso minipterional simple y combinado, es reproducible y que, utilizándolo con un adecuado manejo microquirúrgico, logra buenos resultados en patologías complejas.

Abstract
This is the third paper in a series aimed at finding reionization-era quasars with the combination of DESI Legacy imaging Surveys (DELS), the Pan-STARRS1 (PS1) Survey, and near-infrared imaging surveys, such as the UKIRT Hemisphere Survey (UHS), as well as the Wide-field Infrared Survey Explorer (WISE) mid-infrared survey. In this paper, we describe the updated quasar candidate selection procedure, report the discovery of 16 quasars at 6.4 ≲ z ≲ 6.9 from an area of ∼13,020 deg2, and present the quasar luminosity function (QLF) at z ∼ 6.7. The measured QLF follows

in the magnitude range −27.6 < M
1450 < −25.5. We determine the quasar comoving spatial density at

= 6.7 and M
1450 < −26.0 to be 0.39 ± 0.11 Gpc−3 and find the exponential density evolution parameter to be k = −0.78 ± 0.18 from z ∼ 6 to z ∼ 6.7, corresponding to a rapid decline by a factor of ∼6 per unit redshift toward earlier epochs. This indicates that the rapid decline of quasar spatial density at z > 5 that was found by previous works continues to z > 6, at a rate significantly faster than the average decline rate between z ∼ 3 and 5. We measured quasar comoving emissivity at z ∼ 6.7, which indicates that high-redshift quasars are highly unlikely to make a significant contribution to hydrogen reionization. The broad absorption line quasar fraction at z ≳ 6.5 is measured to be ≳22%. In addition, we also report the discovery of six additional quasars at z ∼ 6 in the Appendix.

Abstract
We perform an ensemble of N-body simulations with 20483 particles for 101 flat wCDM cosmological models sampled based on a maximin distance sliced Latin hypercube design. By using the halo catalogs extracted at multiple redshifts in the range of z = [0,1.48], we develop Dark Emulator, which enables fast and accurate computations of the halo mass function, halo–matter cross-correlation, and halo autocorrelation as a function of halo masses, redshift, separations, and cosmological models based on principal component analysis and Gaussian process regression for the large-dimensional input and output data vector. We assess the performance of the emulator using a validation set of N-body simulations that are not used in training the emulator. We show that, for typical halos hosting CMASS galaxies in the Sloan Digital Sky Survey, the emulator predicts the halo–matter cross-correlation, relevant for galaxy–galaxy weak lensing, with an accuracy better than 2% and the halo autocorrelation, relevant for galaxy clustering correlation, with an accuracy better than 4%. We give several demonstrations of the emulator. It can be used to study properties of halo mass density profiles such as the concentration–mass relation and splashback radius for different cosmologies. The emulator outputs can be combined with an analytical prescription of halo–galaxy connection, such as the halo occupation distribution at the equation level, instead of using the mock catalogs to make accurate predictions of galaxy clustering statistics, such as galaxy–galaxy weak lensing and the projected correlation function for any model within the wCDM cosmologies, in a few CPU seconds.

Abstract
We present and analyze spatially resolved maps for the observed V- and g-band to 3.6 μm flux ratios and the inferred dust-extinction values, A

, for a sample of 257 nearby NGC and IC galaxies. Flux ratio maps are constructed using point-spread function-matched mosaics of Sloan Digital Sky Survey g- and r-band images and Spitzer/InfraRed Array Camera 3.6 μm mosaics, with all pixels contaminated by foreground stars or background objects masked out. By applying the β

V
method, which was recently calibrated as a function of redshift and morphological type by Kim et al., dust-extinction maps were created for each galaxy. The typical 1σ scatter in β

V
around the average, both within a galaxy and in each morphological type bin, is ∼20%. Combined, these result in a ∼0.4 mag scatter in A

V
. β

V
becomes insensitive to small-scale variations in stellar populations once resolution elements subtend an angle larger than that of a typical giant molecular cloud (∼200 pc). We find noticeably redder V−3.6 μm colors in the center of star-forming galaxies and galaxies with a weak active galactic nucleus. The derived intrinsic V−3.6 μm colors for each Hubble type are generally consistent with the model predictions of Kim et al. Finally, we discuss the applicability of the β

V
dust-correction method to more distant galaxies, for which well-matched Hubble Space Telescope rest-frame visible and James Webb Space Telescope rest-frame ∼3.5 μm images will become available in the near-future.

Abstract
We present Period–Luminosity and Period–Luminosity–Color relations at maximum light for Mira variables in the Magellanic Clouds using time-series data from the Optical Gravitational Lensing Experiment (OGLE-III) and Gaia data release 2. The maximum-light relations exhibit a scatter typically up to ∼30% smaller than their mean-light counterparts. The apparent magnitudes of oxygen-rich Miras at maximum light display significantly smaller cycle-to-cycle variations than at minimum light. High-precision photometric data for Kepler Mira candidates also exhibit stable magnitude variations at the brightest epochs, while their multi-epoch spectra display strong Balmer emission lines and weak molecular absorption at maximum light. The stability of maximum-light magnitudes for Miras possibly occurs due to the decrease in the sensitivity to molecular bands at their warmest phase. At near-infrared wavelengths, the period–luminosity relations (PLRs) of Miras display similar dispersion at mean and maximum light with limited time-series data in the Magellanic Clouds. A kink in the oxygen-rich Mira PLRs is found at 300 days in the VI-bands, which shifts to longer periods (∼350 days) at near-infrared wavelengths. Oxygen-rich Mira PLRs at maximum light provide a relative distance modulus, Δμ = 0.48 ± 0.08 mag, between the Magellanic Clouds with a smaller statistical uncertainty than the mean-light relations. The maximum-light properties of Miras can be very useful for stellar atmosphere modeling and distance scale studies provided their stability and the universality can be established in other stellar environments in the era of extremely large telescopes.

Abstract
This is the second in a series of papers devoted to exploring a set of six dusty models of active galactic nuclei (AGN) with available spectral energy distributions. These models are the smooth torus by Fritz et al., the clumpy torus by Nenkova et al., the clumpy torus by Hönig & Kishimoto, the two-phase torus by Siebenmorgen et al., the two-phase torus by Stalevski et al., and the wind model by Hönig & Kishimoto. The first paper explores discrimination among models and the parameter restriction using synthetic spectra. Here we perform spectral fitting of a sample of 110 AGN drawn from the Swift/BAT survey with Spitzer/IRS spectroscopic data. The aim is to explore which is the model that describes better the data and the resulting parameters. The clumpy wind–disk model by Hönig & Kishimoto provides good fits for ∼50% of the sample, and the clumpy torus model by Nenkova et al. is good at describing ∼30% of the objects. The wind–disk model by Hönig & Kishimoto is better for reproducing the mid-infrared spectra of type 1 Seyferts (with 60% of the type 1 Seyferts well reproduced by this model compared to the 10% well represented by the clumpy torus model by Nenkova et al.), while type 2 Seyferts are equally fitted by both models (roughly 40% of the type 2 Seyferts). Large residuals are found irrespective of the model used, indicating that the AGN dust continuum emission is more complex than predicted by the models or that the parameter space is not well sampled. We found that all the resulting parameters for our AGN sample are roughly constrained to 10%–20% of the parameter space. Contrary to what is generally assumed, the derived outer radius of the torus is smaller (reaching up to a factor of ∼5 smaller for 10 pc tori) for the smooth torus by Fritz et al. and the two-phase torus by Stalevski et al. than the one derived from the clumpy torus by Nenkova et al. Covering factors and line-of-sight viewing angles strongly depend on the model used. The total dust mass is the most robust derived quantity, giving equivalent results for four of these models.

Abstract
Importance: As the use of simulation in occupational therapy education continues to increase, so too does the need for continued research on its impact on clinical practice performance and the value of simulation as a pedagogic method.
Objective: To develop a survey to measure the perceived impact of high-fidelity, high-technology simulation experiences during occupational therapy education on occupational therapists’ performance and to describe occupational therapists’ perceptions of the impact of simulation on clinical skills.
Design: Cross-sectional descriptive study.
Setting: Online survey administration.
Participants: Occupational therapists completed an online survey to measure their perceptions of the impact of high-fidelity, high-technology simulation experiences on essential skills in four performance domains: confidence, knowledge, clinical skills, and patient safety skills.
Results: Sixty-seven occupational therapists perceived participation in simulation experiences during occupational therapy education had more impact on transferring clients and using safe body mechanics than on communicating with clients, assessing vital signs, or applying clinical reasoning. The survey items had evidence of content validity, and scores showed good internal consistency reliability.
Conclusions: Survey results suggested high-fidelity, high-technology simulation during occupational therapy education may affect clinical practice performance. Additional research is needed to determine the effectiveness of simulation education in preparing occupational therapists for clinical practice.
What This Article Adds: The survey developed in this study is a reliable measure of the impact of simulation experiences on clinical practice performance of occupational therapists.
The Influence of Topography and Fracking on Cellular Network Availability in Unserved Areas of North Central Pennsylvania
Authors: Cramer Benjamin W. 
Published: October 2019

Abstract
North Central Pennsylvania suffers from sparse cellular network coverage due to the longstanding challenges of low populations and rugged topography that are common in other remote areas. However, in recent years the natural gas (“fracking”) industry has entered the region and enjoys much better network coverage than citizens. Based on field research by the author, this article analyzes the geographical, economic, and political causes of these patterns. The article considers the impact on local citizens and recommends solutions based on existing Pennsylvania law.

Published: October 2019

Na perspectiva de identificar os princípios e concepções que nortearam a elaboração, execução e acompanhamento das políticas educacionais frente à constituição do sistema público de educação, este artigo busca analisar o processo de implantação do regime de colaboração estabelecido entre o município de Rio Branco e o Governo do Estado do Acre, no período entre 2005 e 2012. O estudo se estrutura a partir de pesquisa bibliográfica e documental. Para a construção e caracterização da análise da política pública utilizou-se, por aproximação, o ciclo de políticas, desenvolvido por Ball na década de 90, apresentado por Mainardes (2006), especialmente o contexto de influência que busca identificar e compreender as ideias e fatores que orientam a construção das políticas e o contexto de produção do texto que busca analisar o modo como a política vai se conformando, os quais foram usados como referência para demonstrar a forma como a política de regime de colaboração foi construída e reconstruída em meio as modificações no cenário político do Brasil, do Acre e de Rio Branco. Como um dos resultados do estudo se explicita a implementação do regime de colaboração foi estruturado em relações intergovernamentais institucionalizadas baseadas na dependência do Município em relação ao Estado, reproduzindo um modelo nacional.

The Atlantic Forest is one of the most threatened Brazilian biomes by anthropic action. Thus, the interest inrecovering degraded areas through the use of native tree species has increased, causing a high demand in the use of vigorous seeds. This research aimed at evaluating the suitabilityof the electrical conductivity and accelerated aging tests to evaluate the vigor of C. myrianthum diaspores. For the adequacy of the electrical conductivity test, a completely randomized experimental design (CRD) was used in a 2 x 3 x9 (number of diaspores x volume of water x imbibition time)at a constant temperature of 25 °C. The procedure for the accelerated aging test was conducted at 40 ºC for 0 (no aging), 24, 48 and 72 hours. ACRDwas also used for the accelerated aging test, totaling 4 treatments. The results were submitted to analysis of variance (ANOVA) and the means were compared by the Tukey test at 5% probability. It is concluded that the electrical conductivity test for C. myrianthum diaspores can be conducted with 25 diaspores soaked with 50 mL of deionized water for 96 hours, thus replacing the germination test with the advantage of being carried out in a shorter period of time. Moreover,the 24 and 48 hour accelerated aging period is adequate to discriminate the vigor of C. myrianthum diaspores, with GSI and MGT being the most sensitive variables.

This study shows the phytosociology and floristics of a Dense Ombrophilous Forest fragment under forest management in Portel city, Pará State. Six conglomerates were sampled, divided into secondary and tertiary plots totaling 120 sample units of 0.4 hectares each, in which all trees with diameter at breast height (130 cm above ground; DBH) above 10 cm were measured. These individuals were botanically identified, and evenness and floristic similarity were calculated. There were 3,586 individuals distributed in 42 families, 121 genera, and 174 species. Families Fabaceae, Lecythidaceae, and Sapotaceae were the ones that obtained the highest IVI and the highest representativity of individuals. Species Eschweilera coriacea (DC.) S.A.Mori, Vouacapoua americana Aubl., and Tetragastris altissima (Aubl.) Swart were the ones with the highest IVI. Among the ten highest results, we highlight Syzygiopsis oppositifolia Ducke and Manilkara dardanoi Ducke, with great potential for timber production. The Shannon diversity index averaged 3.83 between the plots, and the Pielou evenness averaged 0.84, showing that the area presents high floristic diversity and great potential for forest management activities.

Introduction: Clinical trials have shown that radium-223 (Ra223) can prolong survival and improve quality of life in patients with metastatic castration-resistant prostate cancer (mCRPC). The objectives of this study were to evaluate pain responses with Ra223 at a population-based level and to determine if there is an association between pain response and alkaline phosphatase (ALP) response.
Methods: All patients from the Vancouver and Kelowna Cancer Centers (CC) in British Columbia who were treated with Ra223 between June 2015 and December 2016 were identified. Patients completed the Brief Pain Inventory (BPI) just prior to each Ra223 injection. Pain response was defined as a two or more point improvement in worst pain relative to baseline, without an increase in pain medication level. ALP was determined at each visit, with a response threshold defined as a 30% decrease from baseline, consistent with the definition of response used in the ALSYMPCA trial.
Results: A total of 65 patients in Vancouver and Kelowna CC received Ra223 during the study period and 56 patients had at least one BPI record, of which 44 (79%) patients were assessable for change in worst pain. Of the assessable patients, 23 (52%, 95% confidence interval [CI] 38–67) had a pain response, although the use of concurrent external beam radiotherapy was a confounder in four cases. Of the 44 patients assessable for change in worst pain, 59% had ALP responses greater than 30%. An ALP response was seen in 56% of pain-responders vs. 43% of non-pain-responders. There was no association between pain response and ALP response (Phi =-0.05; p=0.77).
Conclusions: Ra223 administration was associated with a meaningful pain response rate in this cohort. There was no correlation between pain response and ALP response.
