Background: Stroke is a neurological change that occurs quickly caused by disruption of blood supply to parts of the brain. Stroke has a complex impact which includes bio-psycho-social and spiritual. Various complexities of problems encountered in stroke patients so that self-management is needed as a form of adaptation to new conditions after stroke. Self-management interventions are useful for improving self-management skills and behavior in stroke patients. Purpose this study is to analize effectiveness of self-management interventions in stroke patients. Methods : Narrative literature review, research analyzes published in the online databases of ProQuest, Google scholar and Scopus. The study was selected using the criteria and keywords for the 2015-2019 period.  Seven studies were analyzed using the literature review process. Results: To improve self-management stroke patients self-management interventions are needed. Self-management interventions can be applied in hospitals when post acute patients are hospitalized, preparation for discharge, return and after discharge home and can be combined with rehabilitation programs in the community. Self-management interventions can improve self-efficacy, self-management behavior, activity daily living (ADL) ability, decreased re-hospitalisation and patient readiness to return to the community. Conclusion: Self-management interventions can be applied in Indonesia, with a note that among others prepared human resources, costs, supporting facilities and policies from the manager.
Robert Capa: Una identidad cyborg en la narrativa post-ideológica de un fotógrafo de guerra
Authors: Monje Abril Daniel Enrique , Ortegón Cifuentes Mary Natalia
Published: June 2020

El ejercicio de la fotografía de guerra ha sido analizado históricamente desde todas las ciencias humanas. En estos estudios, generalmente, se ha privilegiado la imagen fotográfica por encima de las narrativas que estructuran la existencia de los fotógrafos de guerra. Esto sucede porque las narrativas que las imágenes técnicas proponen, pueden ser clasificadas, usando el término flusseriano, como post-ideológicas, es decir, narrativas que potencialmente pueden albergar cualquier ideología. En el presente artículo se busca identificar las narrativas emergentes que posibilitan la constitución del fotógrafo como sujeto post-ideológico, apelando para este ejercicio de identificación de narrativas, al trabajo del famoso fotógrafo Robert Capa, debido a la amplia documentación existente sobre su vida y obra. Para realizar este estudio es necesario categorizar a Robert Capa como un cyborg, teniendo en cuenta que parte de las narrativas que lo conforman provienen del aparato fotográfico y otras de su experiencia como ser humano. Se compara su experiencia, con cyborgs contemporáneos suyos como Leni Riefenstahl y con la de aquellas personas que experimentan su legado en forma de narrativa identitaria. En este análisis se identifican algunas de las narrativas que emergen en las construcciones identitarias de los fotógrafos. Estas narrativas, por el hecho de estar asociadas directamente a la relación del fotógrafo con la cámara, posibilitan estructuras postideológicas. Estas narrativas se convierten en complejas construcciones identitarias que trascienden al individuo y se convierten en elementos estructurales del sistema donde se produce la fotografía. Se puede concluir que la ideología asociada a esta práctica está compuesta, tanto por narrativas e ideologías humanas, como maquínicas.
Conservación-restauración de las colecciones arqueológicas de aleación base cobre del Museo Nacional de Al Ain: la importancia de la desalación
Authors: Lois Carrera Diego , Vieira Eduarda , Bosetto Eleonora
Published: June 2020

El Museo Nacional de Al Ain se halla en la ciudad de Al Ain en el Emirato de Abu Dhabi (Emiratos Árabes Unidos). Este Museo preserva una importante colección de objetos neolíticos de aleación base cobre procedentes de diferentes yacimientos localizados en las cercanías de la misma ciudad. Durante el proceso de conservación-restauración de las piezas, se notificó la presencia acusada de iones cloro en la mayoría de los objetos procedentes de los ecosistemas áridos cercanos a la costa donde se encontraron.

Este artículo hace hincapié en los procedimientos de desalación realizados durante el proyecto por ser fundamentales para alcanzar la estabilización de los objetos garantizando su preservación por el mayor tiempo posible. El proceso conocido como B70 ha resultado ser efectivo a pesar de no eliminar todas las sales de los objetos, lo que exige un control de los parámetros ambientales para asegurar la salvaguarda de las colecciones.
Morteros históricos en las construcciones de Quito de los siglos XVI, XVII y XVIII
Authors: Lara Calderon Marco Lenin , Sanz Arauz David , Del Pino Martínez Inés
Published: June 2020

Este artículo tiene como objetivo profundizar en la caracterización de los morteros de revestimiento en la arquitectura colonial de Quito de los siglos XVI, XVII y XVIII. Se parte del supuesto que durante la colonización hubo aportes locales y europeos en la construcción de la arquitectura religiosa de esta ciudad, los resultados que hoy están a la vista son testimonios de este proceso. El análisis de las características compositivas de los morteros, cuyas muestras provienen de los edificios que hoy conocemos, contribuyen a perfeccionar de alguna manera el rompecabezas de la historia, todavía incompleta, ya que las destrucciones producidas por terremotos, y sobre todo intervenciones de restauración o ampliación edilicia han dejado sus huellas en estos edificios.

Oficinas regionais, influências de muitas e desvairadas partes: o caso dos suportes de madeira das pinturas maneiristas de Belchior de Matos da ermida de Geraldes (Peniche, Portugal)
Authors: Cruz António João , Ferreira Elisabete , Lauw Alexandra , Rego Carla , Pereira Helena
Published: June 2020

As duas pinturas, representando Santa Luzia e o Martírio de São Sebastião, feitas por Belchior de Matos (c. 1570-1628) para uma pequena ermida de Peniche, no início do século XVII, têm suportes de madeira que as primeiras observações, realizadas no âmbito de uma intervenção de conservação e restauro, sugeriram ter excelente qualidade e influências de construção que contrastam com o que seria expectável numa encomenda menor de um modesto e mal pago artista de província. Por isso, com o objectivo de aprofundar o caso e contribuir para o conhecimento das pequenas oficinas regionais de pintura do período maneirista, foi feito um estudo pormenorizado desses suportes, incluindo a moldura e a camada de preparação, com recurso a métodos laboratoriais (observação com lupa binocular, fotografia, dendrocronologia, microscopia óptica e FTIR). Concluiu-se, efectivamente, que os painéis mostram que as oficinas regionais de pintura, ao contrário do que se poderia prever, não funcionavam necessariamente isoladas e fechadas sobre si próprias e podiam ter um diversificado conhecimento técnico que, além de soluções originais, envolvia práticas com diferentes origens geográficas, do norte ao sul da Europa, que, com mais estudos de casos, importa esclarecer até que ponto estavam ou não consolidadas em Portugal.
Analysis of urban vulnerability as a tool for cultural heritage preservation. The cases of the medium-sized historical ensembles in Andalusia
Authors: Navas Carrillo Daniel , Del Espino Hidalgo Blanca , Rodríguez-Lora Juan-Andrés , Pérez-Cano Teresa
Published: June 2020

This paper presents the urban vulnerability assessment as a complementary resource in heritage preservation policies, through the analysis of the thirty-nine medium-sized cities that have been listed as Historical Ensemble in Andalusia (Spain). The research seeks to make a sequential approach that addresses, from the general –the conceptual framework on urban vulnerability and the characterization of the analysis sample– to the particular  –the analysis of the socio-economic, socio-demographic or residential vulnerability applied to the intermediate scale which has not been in-deep studied yet–. For this, it proposes to adopt the methodology implemented by the Spanish Ministry of Development in the Atlas of Urban Vulnerability, providing a territorial lecture of the results. The study concludes that medium-sized cities do not present a level of vulnerability lower to the largest ones but detecting specific urban weaknesses that should be addressed to improve the response of these cities to heritage preservation.
The performance of shelters for the conservation of archaeological sites in dry and warm climates: the case of Complutum
Authors: Cabello Briones Cristina
Published: June 2020

Excavated archaeological sites are frequently exposed to damaging environmental conditions, which could lead to rapid decay especially for vulnerable heritage such as mosaics. One of the most common solutions is the construction of shelters; however, some may not behave as expected, either because they do not protect adequately or induce decay. An environmental monitoring programme was undertaken inside and outside the two types of shelters at the Roman archaeological site of Complutum (Alcala de Henares, Spain) from May to September in 2018 and 2019. Hourly temperature and relative humidity readings collected by data loggers, together with rainfall data from a local meteorological station, have been comparatively assessed to better understand the consequences of sheltering in dry and warm areas. The results indicate that both shelters are avoiding further decay by keeping a more stable environment in relation to outside, although the more enclosed structure would be the most suitable one.
Coberturas sostenibles en excavaciones arqueológicas. Metodología de aplicación al caso de mosaicos en el Conjunto Arqueológico de Itálica (Santiponce, Sevilla)
Authors: Ordóñez Martín Manuel , Gómez de Cózar Juan Carlos
Published: June 2020

Es conocido que uno de los retos del trabajo arqueológico, es el de evitar o reducir los efectos del llamado "trauma de excavación", donde la modificación acelerada de condiciones higrotérmicas, junto al efecto de la radiación solar, altera las condiciones de equilibrio del objeto soterrado. Esto lleva a la necesidad de cobertura de yacimientos arqueológicos durante la excavación, realizada frecuentemente mediante sistemas fijos o desmontables más propios del mundo productivo o industrial, de alta huella ecológica, y con efecto limitado, garantizando en su mayoría únicamente situaciones de sombra. No obstante, entendemos que es posible dar una solución global desde la arquitectura a los numerosos requerimientos del objeto excavado, tales como: necesidad de coberturas con mínimos apoyos, coberturas ligeras de gran adaptabilidad a la evolución de la excavación, limitación de costes, o necesidad de control de las condiciones higrotérmicas del espacio cubierto mediante procedimientos limpios que minimicen el impacto medioambiental.
Técnicas analíticas para la caracterización de documentos: una revisión bibliográfica
Authors: Contreras Gemma María , Becerra Luna Javier
Published: June 2020

El interés por la conservación de manuscritos ha crecido en las últimas décadas, bien por su valor artístico o por la información única que custodian. Para ello, es preciso conocer tanto los materiales empleados, como las alteraciones presentes, a fin de discernir el mejor tratamiento de restauración según sus características.

La implementación de técnicas analíticas aplicadas a este campo de estudio ha permitido mejorar el conocimiento sobre el patrimonio documental y bibliográfico. De este modo, se pueden emplear técnicas elementales (energías dispersivas de rayos X, fluorescencia de rayos X, etc.) o moleculares (espectroscopía infrarroja, espectroscopía Raman, etc.) para analizar los materiales inorgánicos u orgánicos. Si bien muchos de estos estudios han estado encaminados a estudiar manuscritos iluminados, es importante prestar especial atención a los estudios publicados sobre la caracterización de tintas metalográficas, las cuales se relacionan con la preservación de la información y con la degradación del soporte. El empleo de técnicas de imagen (microscopía óptica, fotografía infrarroja, microscopía electrónica, etc.) permite complementar los estudios de diagnóstico e identificación de materiales. Sin embargo, un conocimiento pormenorizado del manuscrito estudiado requiere del diseño de un protocolo de estudio en el que se complemente la información obtenida mediante la selección de las técnicas más adecuadas en función de las características del manuscrito y la disponibilidad de estas.

El objetivo principal de este artículo es simplificar la toma de decisiones en torno a la selección de técnicas analíticas y no solo dar una revisión bibliográfica de los principales estudios sobre el análisis de soportes y materiales respaldados. Además, se ha diseñado un protocolo que facilita al restaurador la selección de técnicas analíticas en función del material a caracterizar y los recursos disponibles.
Geology of the Lower Cretaceous in the Falkebjerg area, Wollaston Forland, northern East Greenland
Authors: Piasecki Stefan , Bojesen-Koefoed Jørgen A. , Alsen Peter
Published: June 2020

New data on the Lower Cretaceous Falskebugt Member (Palnatokes Bjerg Formation) and Stratumbjerg Formation in easternmost Wollaston Forland, northern East Greenland, are interpreted here. The type locality of the Falskebugt Member on the north-west corner of the Falkebjerg ridge has been revisited, and additional new good exposures were found in a riverbed just north of Falkebjerg and more in river beds on the plain further to the north, where both the Falskebugt Member and the Stratumbjerg Formation are exposed. Previously, only a limited marine fauna was reported providing a restricted middle Valanginian age of the Falskebugt Member. New fossil faunas in other parts of the Falskebugt Member suggest an early Valanginian – Hauterivian age and confirm lateral correlation with the Albrechts Bugt and Rødryggen Members of the Palnatokes Bjerg Formation. However, in places where the Falskebugt Member is exposed in contact with the lower Stratumbjerg Formation, dinoflagellate cysts from these units indicate Barremian and late Barremian ages, respectively. The stratigraphic range of the combined biostratigraphic data from the Falskebugt Member indicates an early Valanginian – late Barremian age. Dinoflagellate cysts from part of the assemblage in the Stratumbjerg Formation suggest a marginal marine/brackish water depositional environment. Comparable depositional environments are also recorded in upper Barremian sediments on Store Koldewey and in the Ladegårdsåen Formation on Peary Land much farther to the north in Greenland. The dark mudstones of the Stratumbjerg Formation show no potential for generation of liquid hydrocarbons, and the immature and poorly sorted sediments of the Falskebugt Member have little potential as a petroleum reservoir.
4-Hydroxy-3-methyl-2(1H)-quinolone, originally discovered from a Brassicaceae plant, produced by a soil bacterium of the genus Burkholderia sp.: determination of a preferred tautomer and antioxidant activity
Authors: Li Dandan , Oku Naoya , Shinozaki Yukiko , Kurokawa Yoichi , Igarashi Yasuhiro
Published: June 2020

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with 13C chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 μM, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.
Guiding a supersonic controlled object in a multi-position air basing radar
Authors: Markevich V. E. , Legkostup V. V.
Published: June 2020

The possibility of control of a guided supersonic aviation unmanned interceptor on a moving target in an autonomous airborne multi-position radar station has been investigated. To obtain the coordinate information, the algorithm of difference-range finding and difference range-Doppler spatial measurements is selected using a limited number of transmitting positions that do not provide an unambiguous determination of the coordinates and speed of the object with high accuracy. The paper proposes various approaches to eliminate a priori uncertainty regarding the estimated coordinates in a limited set of measuring radio engineering positions.

An analytical method is considered for constructing an optimal state control device for a nonlinear multidimensional and multiply connected dynamic object, taking into account the constraints, which allows one to obtain finite computational relations in a closed algebraic form. The control device was synthesized using measurements in the Cartesian and spherical coordinate systems, several varieties of the combined method of pointing a controlled object to an instant meeting point were obtained. The given guidance algorithms are a generalization of the method of proportional navigation widely used in practice and its modifications. A distinctive feature of the synthesized algorithms is the natural accounting for the nonlinear, multidimensional, and multiply connected structure of the control object, as well as the parameters of unsteady perturbations (acceleration of gravity, projections of the longitudinal acceleration of the object and acceleration of the target’s maneuver) that act in the guidance process.

The unified kinematic differential equations that describe the dynamics of the control object, are obtained, and they can be used to synthesize a controller that operates according to switched or smoothly matched non-stationary optimality criteria (target functions, target integral manifolds). The developed algorithms can be used in the design of autonomous homing and telecontrol systems, implemented in hardware and software both on board an unmanned aerial or artillery interceptor, and as a part of autonomous multiposition airborne radar stations.
Protein homodimers structure prediction based on deep neural network
Authors: Hadarovich A. Y. , Kalinouski A. A. , Tuzikov A. V.
Published: June 2020

Structural prediction of protein-protein complexes has important application in such domains as modeling of biological processes and drug design. Homodimers (complexes which consist of two identical proteins) are the most common type of protein complexes in nature but there is still no universal algorithm to predict their 3D structures. Experimental techniques to identify the structure of protein complex require enormous amount of time and resources, and each method has its own limitations. Recently Deep Neural Networks allowed to predict structures of individual proteins greatly prevailing in accuracy over other algorithmic approaches. Building on the idea of this approach, we developed an algorithm to model the 3D structure of homodimer based on deep learning. It consists of two major steps: at the first step a protein complex contact map is predicted with the deep convolutional neural network, and the second stage is used to predict 3D structure of homodimer based on obtained contact map and optimization procedure. The use of the neural network in combination with optimization procedure based on gradient descent method allowed to predict structures for protein homodimers. The suggested approach was tested and validated on a dataset of protein homodimers from Protein Data Bank (PDB). The developed procedure could be also used for evaluating protein homodimer models as one of the stages in drug compounds developing.

Authors: Yarmolik V. N. , Mrozek I. , Yarmolik S. V.
Published: June 2020

The relevance of testing of memory devices of modern computing systems is shown. The methods and algorithms for implementing test procedures based on classical March tests are analyzed. Multiple March tests are highlighted to detect complex pattern-sensitive memory faults. To detect them, the necessary condition that test procedures must satisfy to deal complex faults, is substantiated. This condition is in the formation of a pseudo-exhaustive test for a given number of arbitrary memory cells. We study the effectiveness of single and double application of tests like MATS ++, March C– and March A, and also give its analytical estimates for a different number of k ≤ 10 memory cells participating in a malfunction. The applicability of the mathematical model of the combinatorial problem of the coupon collector for describing multiple memory testing is substantiated. The values of the average, minimum, and maximum multiplicity of multiple tests are presented to provide an exhaustive set of binary combinations for a given number of arbitrary memory cells. The validity of analytical estimates is experimentally shown and the high efficiency of the formation of a pseudo-exhaustive coverage by tests of the March A type is confirmed.
Object detection in high resolution images based on multiscale and block processing
Authors: Bohush R. P. , Zakharava I. Yu. , Ablameyko S. V.
Published: June 2020

In the paper the algorithm for object detection in high resolution images is proposed. The approach uses multiscale image representation followed by block processing with the overlapping value. For each block the object detection with convolutional neural network was performed. Number of pyramid layers is limited by the Convolutional Neural Network layer size and input image resolution. Overlapping blocks splitting to improve the classification and detection accuracy is performed on each layer of pyramid except the highest one. Detected areas are merged into one if they have high overlapping value and the same class. Experimental results for the algorithm are presented in the paper.

Komparatif Kontruksi Isu pada Berita Pengangkatan Basuki Tjahaja Purnama sebagai Komisaris Utama Pertamina
Authors: Wahjudi Sugeng , Andreas Praditya Tegar Pradana
Published: June 2020

Isu mengenai Pengangkatan Basuki Tjahaja Purnama sebagai Komisaris Utama Pertamina menjadi pemberitaan hangat oleh media. Media massa yang merupakan saluran komunikasi massa memiliki kekuatan besar membentuk opini publik. Hal tersebut dikarenakan dalam melakukan pemberitaannya, media diyakini telah melakukan konstruksi atas realitas agar sesuai dengan ideologi media. Penulis melakukan analisis pembingkaian berita (framing analysis) terhadap Harian Kompas dan Media Indonesia dalam melakukan pemberitaan terkait dengan isu ini. Metode yang digunakan Analisis Framing Pan dan Kosicki dengan  paradigma konstruktivisme, dengan tujuan melihat bagaimana kedua media melakukan konstruksi atas fenomena tersebut. Sifat dari penelitian ini adalah komparatif karena penulis ingin membandingkan perbedaan sudut pandang kedua media cetak tersebut. Hasil yang didapat dari penelitian ini ditemukan bahwa media Harian Kompas telihat lebih kredibel dan netral dalam melakukan pemberitaan. Hal tesebut dapat dilihat dari kelengkapan unsur berita, penggunaan data penunjang dalam menyampaikan fakta, penggunaan lebih dari dua narasumber dan penggunaan bahasa yang lebih netral. Sementara Media Indonesia terlihat kurang kredibel dan sedikit memihak pada sosok Basuki Tjahaja Purnama. Hal tersebut dapat terlihat dari kurang lengkapnya unsur berita, kurangnya data dan narasumber serta penggunaan bahasa yang terlihat mendukung sosok Basuki.

Authors: AKPINAR KOCAKULAK Neşe , TAHERİ Serpi , ŞENER Elif Funda , AYCAN Kenan , ÖZKUL Yusuf
Published: June 2020

Background: exercise conditions can affect the expression of genes. Our study investigated the effects of acute and chronic exercise on the expression of genes related to oxidative stress (Tfam,UCP2,UCP3 ) and immune system (IL-1α,IL-1β,IL-2,IL-8,IL12A,IL12B,TLR2,TLR4 ).
Methods: was formed with 24 people: 12 healthy females and 12 healthy males. Maximal oxygen use capacities of the participants were determined by the Bruce test protocol at the beginning and end of the 8-week training program. After calculating their maximal oxygen use capacity, each participant was given a acute running exercise on the tread mill at the speed and incline that the participant would reach to his/her maxVO2 until exhausted. The same people was built to continuous runs (%50-70) for 8 weeks in a week, and two days of medium-term interval training program (%90-95). Peripheral blood samples were taken before and after acute exercise with immediately after chronic exercises. RNA isolation was performed using TRIzol Reagent from peripheral blood mononuclear cells. Gene expression was determined by Biomark Real-Time PCR (RT-PCR). Comparisons were performed by using two independent sample t-test and Mann-Whitney U for quantitative data and calculated gene expression values. The statistical significance level was taken as p <0,05. Results: we found that acute exercise in women changed Tfam gene expression (p <0,05 ). Chronic exercise changes the expression level of more genes (Tfam, IL-1β, TLR4 ) in women (p<0.05,p<0.001). There was only difference in Tfam gene in males (p <0,05 ). Conclusions: changes in gene expression differed by sex in exercise. Our results indicate that different workout programs for females and males cause genes to work and they have a positive effect on their expressions and thus increase the efficiency of the exercise.

LOGISTICS PERFORMANCE INDEX IN INTERNATIONAL TRADE: CASE OF CENTRAL AND EASTERN EUROPEAN AND WESTERN BALKANS COUNTRIES
Authors: Bugarčić Filip Ž. , Skvarciany Viktorija , Stanišić Nenad
Published: June 2020

The volume of international trade heavily depends on factors facilitating trade and contributing to reducing its costs.
The importance of international logistics as trade facilitator is increasingly emphasised in the literature. The aim of the paper is to assess
the level of the impact of logistics performance on trade volume in the Central and Eastern European countries (CEECs) and Western Balkans.
In order to achieve the aim, the impact of Logistic Performance Index (LPI) on international trade in 2007 and 2018 is investigated. This
relationship is examined using the gravity model approach with a focus on overall LPI and its components. The research results show that
there is a positive statistical significance and impact of logistics on bilateral trade between CEECs, and logistics justifies the role of
a trade facilitator. Besides, the importance of LPI components in intensifying international trade was emphasised. Research implications
indicate that improving logistics performance and logistics services lead to a positive impact on the volume of international trade. Better
logistics performance in trading countries will lead to increased bilateral trade and reduced trade costs. The limitation of the research
is that only two years have been taken into account. This is done in order to highlight the differences between the year the LPI was introduced,
and the last year the LPI was calculated.

Published: June 2020

The development of Corporate Social Responsibility (CSR) initiative is formed by several cultural, economic, social, political and institutional factors which have an impact on setting the priorities and advancement of CSR practices. The aim of this study is to assess CSR performance at the country level. In order to achieve this aim, the main drivers and barriers of CSR initiatives were identified and systematized based on literature review. The policies to address these barriers were analysed and discussed. The framework for the assessment of CSR performance was developed based on the analysis and assessment of the quality of political-regulatory, economic and social environment, implemented public policies to promote CSR and successes that were achieved by countries in implementing recommendations for public policy advancement. The indicators from Venture Capital and Private Equity Country Attractiveness Index, CSR policies areas reviews and EU recommendations for the improvement of public policies linked to the CSR were applied for assessing the CSR performance. The empirical analysis and the assessment of CSR performance in the Baltic States was performed based on the developed framework and policy recommendations that were developed for other countries, taking into account the priorities of “The Belt and Road” project that was initiated by the Chinese government and aiming at sustainable development and global risk mitigation.

Interstellar pickup ions (PUI) are interstellar neutrals that have been ionized in transit through the heliosphere via charge exchange or photoionization. These new PUIs then “freeze” into the solar wind (SW) and move with the bulk SW velocity (V
SW). They also begin to gyrate around the local magnetic field with V
SW, resulting in a maximum PUI velocity of 2 ∗ V
SW. Understanding how He+ PUIs are accelerated at shocks in space provides valuable insights into shock dynamics and shock acceleration mechanisms. On 2018 January 8, while the Magnetospheric Multiscale (MMS) Mission was in the SW, it observed the forward shock of a corotating interaction region. In this work, we analyze the upstream and downstream velocity distributions of He+ for this quasiperpendicular, marginally supercritical (θ
Bn = 67°, M

A
= 2.8) interplanetary shock. We derive average two-dimensional pitch-angle distributions in the field-aligned SW frame, as well as reduced one-dimensional velocity distributions for selected upstream and downstream intervals. We find that the shock accelerates He+ largely perpendicular to the magnetic field, consistent with shock reflection. Furthermore, we derive a measured ratio of accelerated He+ ions by estimating a maximum speed in the downstream frame, above which we assume that He+ ions have been accelerated by their interaction with the shock. The measured acceleration ratio, R
Measured = 0.14, is then compared to a theoretical ratio derived from a simple model of the upstream distribution, R
Theoretical = 0.06.

Galactic black hole (BH) candidate MAXI J1348–630 was recently discovered by MAXI and Swift/BAT satellites during its first outburst in 2019 January, which continued for ∼4 months. We study the spectral and timing properties of the source in detail. The combined 1–150 keV Swift/XRT, Swift/BAT, and MAXI/GSC spectra are investigated with the two-component advective flow (TCAF) solution. Physical flow parameters of TCAF, such as the Keplerian disk accretion rate, the sub-Keplerian halo accretion rate, the shock location, and the shock compression ratio, are estimated from our spectral fits. Based on the variation of flux in soft and hard X-ray ranges, the hardness ratio, TCAF model fitted accretion rates, and the accretion rate ratio, we show how the source evolved through four spectral states, viz., hard, hard-intermediate, soft-intermediate, and soft, in rising and declining states. Low-frequency quasi-periodic oscillations are observed in two observations during the rising phase of the outburst. From the spectral analysis, we estimate the mass of the BH to be

M
⊙. We also find that the viscous timescale in this outburst is ∼3.5 days. The distance of the source is also estimated as 5–10 kpc from state transition luminosity.

Published: June 2020

The design and implementation of a new framework for adaptive mesh refinement calculations are described. It is intended primarily for applications in astrophysical fluid dynamics, but its flexible and modular design enables its use for a wide variety of physics. The framework works with both uniform and nonuniform grids in Cartesian and curvilinear coordinate systems. It adopts a dynamic execution model based on a simple design called a “task list” that improves parallel performance by overlapping communication and computation, simplifies the inclusion of a diverse range of physics, and even enables multiphysics models involving different physics in different regions of the calculation. We describe physics modules implemented in this framework for both nonrelativistic and relativistic magnetohydrodynamics (MHD). These modules adopt mature and robust algorithms originally developed for the Athena MHD code and incorporate new extensions: support for curvilinear coordinates, higher-order time integrators, more realistic physics such as a general equation of state, and diffusion terms that can be integrated with super-time-stepping algorithms. The modules show excellent performance and scaling, with well over 80% parallel efficiency on over half a million threads. The source code has been made publicly available.
A Monte Carlo Implementation of Galactic Free–Free Emission for the EoR Foreground Models

Published: June 2020

The overwhelming foreground causes severe contamination on the detection of 21 cm signal during the Epoch of Reionization (EoR). Among various foreground components, the Galactic free–free emission is less studied, so that its impact on the EoR observation remains unclear. To better constrain this emission, we perform Monte Carlo simulation of Hα emission, which comprises direct and scattered Hα radiation from H ii regions and warm ionized medium (WIM). The positions and radii of H ii regions are quoted from the Wide-Field Infrared Survey Explorer H ii catalog, and the WIM is described by an axisymmetric model. The scattering is off dust and free electrons that are realized by applying an exponential fitting to the HI4PI H i map and an exponential disk model, respectively. The simulated Hα intensity, the Simfast21 software, and the latest SKA1-Low layout configuration are employed to simulate the SKA “observed” images of Galactic free–free emission and the EoR signal. By analyzing the one-dimensional power spectra, we find that the Galactic free–free emission can be about 105.4–102.1, 105.0–101.7, and 104.3–101.1 times more luminous than the EoR signal on scales of

in the 116–124, 146–154, and 186–194 MHz frequency bands, respectively. We further calculate the two-dimensional power spectra inside the EoR window and show that the power leaked by Galactic free–free emission can still be significant, as the power ratios can reach about 110%–8000%, 30%–2400%, and 10%–250% on scales of

in three frequency bands. Therefore, we indicate that the Galactic free–free emission should be carefully treated in future EoR detections.
The Effects of Nucleoside/Nucleotide Analogues on Host Immune Cells: The Baseline for Future Immune Therapy for HBV?
Authors: Boeijen Lauke L , Spaan Michelle , Boonstra André
Published: June 2020

HBV is a non-cytopathic virus and the progression of liver fibrosis is attributed to the host immune response. Complete suppression of viral replication using nucleotide or nucleoside analogues (NUCs) can prevent most complications related to chronic HBV infection. Unfortunately, antiviral treatment has to be administered lifelong to the majority of patients as HBV persists in the hepatocytes. However, although NUCs are very frequently administered in clinical practice, their effects on vital parts of the host immune response to HBV are not well established. In this review we summarize the currently available data gathered from longitudinal studies that investigated treatment-associated alterations of HBV-specific CD4+ and CD8+ T-cells, regulatory T-cells and natural killer (NK) cells. These observations are important, as they can guide the design of studies that investigate the efficacy of new immune therapeutic agents. Novel experimental compounds will likely be added to ongoing NUC treatment, which leads to a functional cure in only a small minority of patients.
