Published: January 2019

BackgroundExpediting cancer diagnosis is widely perceived as one way to improve patient outcomes. Evidence indicates that lymphoma diagnosis is often delayed, yet understanding of issues influencing this is incomplete.AimTo explore patients’ and their relatives’ perceptions of disease-related factors affecting time to diagnosis of Hodgkin and non-Hodgkin lymphoma.Design and settingQualitative UK study involving patients with indolent and aggressive lymphomas, and their relatives, from an established population-based cohort in the north of England.MethodSemi-structured interviews with 35 patients and 15 of their relatives. Interviews were audiorecorded and transcribed, and qualitative descriptive analysis was undertaken.ResultsParticipant accounts suggest that certain features of lymphoma can impact on patients’ and healthcare providers’ (HCPs) responses to disease onset. Three characteristics stand out: disease occurrence (rare), manifestation (varied), and investigative options (often inconclusive). Interviewees described how they, and some HCPs, lacked familiarity with lymphoma, seldom considering it a likely explanation for their symptoms. Symptoms reported were highly variable, frequently non-specific, and often initially thought to be associated with various benign, self-limiting causes. Blood tests and other investigations, while frequently able to detect abnormalities, did not reliably indicate malignancy. Interviewees reported the potential for improvements among HCPs in information gathering, communication of uncertainty, and re-presentation advice for non-resolving/progressive health changes.ConclusionThis study demonstrates the complex characteristics of lymphoma, perceived by patients as prolonging time to diagnosis, often despite significant effort by themselves, their relatives, and HCPs to expedite this process. The findings also illustrate why simple solutions to delayed diagnosis of lymphoma are lacking.

Abstract
During the past five years, 6, 7, and 26 transit observations were carried out for the HAT-P-9b, HAT-P-32b, and HAT-P-36b systems, respectively, through the Transiting Exoplanet Monitoring Project network. Combined with the published photometric data and radial-velocity measurements, our new photometry allows us to revisit the system parameters and search for additional close-in planetary companions in these hot Jupiter systems. We measure an updated R

P
/R
* = 0.1260 ± 0.0011 for HAT-P-36 system in the R band, which is 4.5σ larger than the published i-band radius ratio of 0.1186 ± 0.0012. We also perform a transit timing variation (TTV) analysis for each system. Because no significant TTVs were found, we place an upper mass limit on an additional planet for each system.

Abstract
We report a multi-objective campaign of targeted 21 cm H i line observations of sources selected from the Arecibo Legacy Fast Arecibo L-band Feed Array (ALFALFA) survey and galaxies identified by their morphological and photometric properties in the Sloan Digital Sky Survey. The aims of this program have been (1) to confirm the reality of some ALFALFA sources whose enigmatic nature suggest additional multiwavelength observations; (2) to probe the low signal-to-noise ratio (S/N) regime, below the ALFALFA reliability limit; and (3) to explore the feasibility of using optical morphology, color, and surface brightness to identify gas-rich objects in the region of the Pisces–Perseus Supercluster (PPS) whose H i fluxes are below the ALFALFA sensitivity limit at that distance. As expected, the reliability of ALFALFA detections depends strongly on the S/N of the H i line signal and its coincidence with a probable stellar counterpart identified by its optical properties, suggestive of ongoing star formation. The identification of low-mass, star-forming populations enables targeted H i line observations to detect galaxies with H i line fluxes below the ALFALFA sensitivity limits in fixed local volumes (D < 100 Mpc). The method explored here serves as the basis for extending the sample of gas-bearing objects as part of the ongoing Arecibo Pisces–Perseus Supercluster Survey (APPSS).
Optical Spectroscopic Survey of a Sample of Unidentified Fermi Objects: II
Authors: Paiano Simona , Falomo Renato , Treves Aldo , Franceschini Alberto , Scarpa Riccardo 
Published: January 2019

Abstract
We report on optical spectroscopy obtained at the 10.4 m Gran Telescopio Canarias of 28 Fermi γ-ray sources that completes the study of a sample of 60 targets of unidentified objects for which the detection of an X-ray and/or radio source inside the 3FGL error box is available. The observations aim to characterize the nature and measure the redshift of these sources. For all optical counterparts, the observations allow us to establish their active galactic nucleus nature. In particular, we found 24 BL Lac objects, one quasar, one narrow line Seyfert 1, and two objects showing spectral features typical of Seyfert 2 galaxies. For most of these, we determine a spectroscopic redshift, while for five we can set lower limits based on the lack of stellar features from the host galaxy. The global properties of the full sample are briefly discussed.
Signature of r-mode Gravitational-wave Emission in the X-Ray Afterglow of Short GRB 090510
Authors: Lin Jie , Lu Rui-Jing 
Published: January 2019

Abstract
The X-ray plateaus observed in the afterglows of some short gamma-ray bursts (GRBs) are usually interpreted as the contribution from newborn magnetars with magnetic dipole radiation. However, Fan et al. re-examined that interpretation and found that a rapidly rotating magnetar might lose most of the angular momentum to gravitational waves because the total energy released within the X-ray plateau phases in some short GRBs was much smaller than that expected in the magnetar model, which indicates that the signal of gravitational-wave radiation (GWR) might have already existed in current electromagnetic data of short GRBs. In addition, theoretical analysis also showed that the rotational energy of newborn magnetars was carried away via GWR, which was more efficient than magnetic dipole radiation and the shape of the light curve of GRB can be adjusted from the magnetar model merely by considering magnetic dipole radiation. With this motivation, we investigate the X-ray light curve of GRB 090510 in detail and find that the X-ray light curve can be well fit with a magnetar model supposing that the spin evolution of the magnetar is governed by both gravitational radiation generated by unstable r-mode oscillations at early-time and magnetic dipole radiation dominating late-time spin-down evolution. This result suggests that the r-mode instability is likely to play an important role in the evolution of the post-merger remnant. We also discuss the detectability of the r-mode GWR emitted by the long-lived remnant of GRB 090510.
The Induced Surface Tension Contribution for the Equation of State of Neutron Stars
Authors: Sagun Violetta V. , Lopes Ilídio , Ivanytskyi Aleksei I. 
Published: January 2019

Abstract
We apply a novel equation of state (EoS) that includes the surface tension contribution induced by interparticle interaction and asymmetry between neutrons and protons, to the study of neutron star (NS) properties. This elaborated EoS is obtained from the virial expansion applied to multicomponent particle mixtures with hard core repulsion. The considered model is in full concordance with all the known properties of normal nuclear matter, provides a high-quality description of the proton flow constraints, hadron multiplicities created during the nuclear–nuclear collision experiments, and equally is consistent with astrophysical data coming from NS observations. The analysis suggests that the best model parameterization gives the incompressibility factor K
0, symmetry energy J, and symmetry energy slope L at normal nuclear density equal to 200 MeV, 30 MeV, and 113.28–114.91 MeV, respectively. The mass–radius relations found for NSs computed with this EoS are consistent with astrophysical observations.

Abstract
Metal Evolution, Transport, and Abundance in the LMC (METAL) is a large Cycle 24 program on the Hubble Space Telescope aimed at measuring dust extinction properties and interstellar depletions in the Large Magellanic Cloud (LMC) at half-solar metallicity. The 101-orbit program is composed of Cosmic Origins Spectrograph and Space Telescope Imaging Spectrograph spectroscopy toward 33 LMC massive stars between 1150 and 3180 Å and parallel Wide Field Camera 3 imaging in seven near-UV to near-IR filters. The fraction of silicon in the gas phase (depletion) obtained from the spectroscopy decreases with increasing hydrogen column density. Depletion patterns for silicon differ between the Milky Way, LMC, and SMC, with the silicon depletion level offsetting almost exactly the metallicity differences, leading to constant gas-phase abundances in those galaxies for a given hydrogen column density. The silicon depletion correlates linearly with the absolute-to-selective extinction, R

V
, indicating a link between gas depletion and dust grain size. Extinction maps are derived from the resolved stellar photometry in the parallel imaging, which can be compared to far-IR images from Herschel and Spitzer to estimate the emissivity of dust at LMC metallicity. The full METAL sample of depletions, UV extinction curves, and extinction maps will inform the abundance, size, composition, and optical properties of dust grains in the LMC, comprehensively improve our understanding of dust properties, and improve the accuracy with which dust-based gas masses, star formation rates, and star formation histories in nearby and high-redshift galaxies are estimated. This overview paper describes the goals, design, data reduction, and initial results of the METAL survey.

Abstract
We study the evolution of star-forming galaxies with

over the redshift range of 0.7 < z < 1.2 using the emission-line galaxies (ELGs) in the extended Baryon Oscillation Spectroscopic Survey (eBOSS). By applying the incomplete conditional stellar mass function (SMF) model proposed in Guo et al., we simultaneously constrain the sample completeness, the stellar–halo mass relation (SHMR), and the quenched galaxy fraction. We obtain the intrinsic SMFs for star-forming galaxies in the redshift bins of 0.7 < z < 0.8, 0.8 < z < 0.9, 0.9 < z < 1.0, and 1.0 < z < 1.2, as well as the SMF for all galaxies in the redshift bin of 0.7 < z < 0.8. We find that the eBOSS ELG sample only selects about 1%–10% of the star-forming galaxy population at the different redshifts, with the lower redshift samples more complete. There is only weak evolution in the SHMR of the ELGs from z = 1.2 to z = 0.7, as well as the intrinsic galaxy SMFs. Our best-fitting models show that the central ELGs at these redshifts live in halos of mass M ∼ 1012
M
⊙, while the satellite ELGs occupy slightly more massive halos of M ∼ 1012.6
M
⊙. The average satellite fraction of the observed ELGs varies from 13% to 17%, with the galaxy bias increasing from 1.1 to 1.4 from z = 0.7 to 1.2.
Magnetohydrodynamic Simulations for Solar Active Regions using Time-series Data of Surface Plasma Flow and Electric Field Inferred from Helioseismic Magnetic Imager Vector Magnetic Field Measurements
Authors: Hayashi Keiji , Feng Xueshang , Xiong Ming , Jiang Chaowei 
Published: January 2019

Abstract
Temporal evolution of magnetic structures of the solar active region (AR) NOAA AR 11158, is simulated with our magnetohydrodynamic (MHD) simulation models using time-dependent solar-surface electric field or plasma flow data. Using the Solar Dynamics Observatory/Helioseismic Magnetic Imager vector magnetogram data, the solar-surface boundary electric field maps are derived with our recently developed algorithm to reproduce the temporal evolution of solar-surface vector magnetic field as observed. The plasma motion velocity maps are calculated through the Differential Affine Velocity Estimator for Vector Magnetograms. In both data-driven models, the simulated evolutionary magnetic field structures at strong-field low-beta regions appear near force-free state, as the current helicity density (

) are roughly constant along each field line. Although the magnetic energy simulated with the newly developed plasma-velocity-driven model is about 10% of that by the electric-field driven model, the plasma-velocity-driven model can maintain the frozen-in condition, and evolution of current and free energy generated by the solar-surface plasma motions can be spatially and temporally traced. The present MHD simulation models for AR system can be a step toward better, more realistic data-driven evolutionary modeling, in particular, establishing boundary treatments for introducing the time-dependent observation data in a physically and mathematically consistent manner.

AIM: To investigate the efficacy of plastic surgery in the treatment of giant congenital melanocytic nevus (GCMN).
METHODS: We enrolled 20 patients with 44 lesions and performed one of the following procedures: serial excision, skin grafting, tissue expansion, primary skin closure, distant flap, and adjacent flap. We assessed the outcome at 10 days and 6 months after surgery.
RESULTS: Of 44 surgical sites, the most commonly used reconstruction surgeries were serial excision (16), skin grafting (16), and tissue expansion (6). Other types were rarely used. All patients with serial excision had good outcome. A total of 81% and 19% of the patients with skin grafting had good and fair outcome, respectively. Around 83% and 17% of the patients with tissue expansion had good and fair outcome. No cases had bad outcome.
CONCLUSION: In conclusion plastic surgery is effective in the treatment of GCMN. There are different techniques but serial excision, skin grafts, and tissue expansion are most commonly used.

Published: January 2019

Background:
Acquisition of evidence-based practice (EBP) competencies in graduate-level nursing programs bridges the research–practice gap in professional practice. This study evaluated the impact of the Star Model of Knowledge Transformation as a framework for course design on graduate-level nursing students' perceived EBP competencies.

Method:

Data were collected from 2012 to 2017 (
N
= 544). Repeated-measures ANOVA was used to analyze pre- and postassessment data over time. Data were collected for each of the five stages or Star Points of EBP competencies.

Results:

Significant postcourse improvement in perceived EBP competencies was demonstrated (
p
≤ .000) for all Star Points and years. The greatest pre- and postassessment percentage change occurred in the Translation Star Point scores and the least percentage change occurred in Discovery.

Conclusion:

These data support the use of intentional course design based on a recognized EBP model to improve perceived EBP competencies in Master of Science in Nursing students.

A Novel Model for Securing Mobile-based Systems against DDoS Attacks in Cloud Computing Environment
Authors: El-Sofany Hosam , Abou El-Seoud Samir 
Published: January 2019

the increasing growth of mobile devices technology and Mobile-based systems with the emerging of cloud computing technology, created a Mobile Cloud Computing field to be the recent future technology for different wireless services. The development of Mobile-based system under cloud computing environment solve some performance and environment related issues include: bandwidth, storage capacity, availability, scalability and heterogeneity. The Mobile-based cloud computing apps are different comparing to mobile computing apps, since in the first model the devices run cloud based web applications not as mobile computing native apps. Services of Mobile-based systems via cloud are accessing and sharing through internet connection thus they are open for attacker to attack on its security. Distributed Denial of Service (DDoS) attacks can cause a big problem in mobile cloud computing security. The main objective of DDoS attacks is to infect wireless devises resources (e.g., software applications, wireless network, etc.) and make them unavailable to the authorized user. In DDoS, the attacker tries to overload the Mobile-based service with traffic. The main objective of this research paper is to introduce novel model for securing Mobile-based systems against DDoS attacks. Efficiency and performance analysis evaluations of the proposed model are presented. The feedbacks of the experimental results were highly promising, for protecting mobile-based cloud computing systems against DDoS attacks.
Comparative analysis of MODIS, MISR, and AERONET climatology over the Middle East and North Africa
Authors: Farahat Ashraf 
Published: January 2019

Abstract. Comparative analysis of Multi-angle Imaging SpectroRadiometer (MISR),
Moderate Resolution Imaging Spectroradiometer (MODIS),
and Aerosol Robotic Network (AERONET) aerosol optical depth (AOD) products is performed
over seven AERONET stations located in the Middle East and North Africa for
the period of 2000–2015. Sites are categorized into dust, biomass burning,
and mixed aerosol conditions. MISR and MODIS AOD agree during high-dust seasons but MODIS tends
to underestimate AOD during low-dust seasons. Over dust-dominated sites,
MODIS/Terra AODs indicate a negative trend over time, while
MODIS/Aqua, MISR, and AERONET depict a positive trend. A deviation between
MODIS/Aqua and MODIS/Terra was observed regardless of the geographic location
and data sampling. The performance of MODIS is similar over the entire region
with ∼64 % of AOD within the Δτ=±0.05±0.15τAERO
confidence range. MISR AOD retrievals fall within 84 % of the same
confidence range for all sites examined here. Both MISR and MODIS capture
aerosol climatology; however few cases were observed where one of the two
sensors better captures the climatology over a certain location or AOD range
than the other sensor. AERONET Level 2.0 version 3, MODIS Collection 6.1,
and MISR V23 data have been used in analyzing the results presented in this study.
A PEDAGOGIA KANTIANA: O SUJEITO MORAL COMO FOCO DA EDUCAÇÃO
Authors: Cerqueira Samira da Silva , Euzebio Marcos Sidnei Pagotto 
Published: January 2019

O presente estudo tem como objetivo fazer uma breve análise acerca do sujeito moral como parte central da educação segundo Kant. Para o filósofo alemão, a educação está intimamente relacionada com a moral, haja vista que o homem não nasce com ela em si, todavia, torna-se moral através da educação, mas, para um maior entendimento dessas questões é, antes de tudo, necessária uma breve exposição sobre o período histórico-cultural em que viveu Kant, o Iluminismo. Dessa forma, o principal papel da educação é aguçar no aluno o seu juízo, juntamente com a prática de uma pedagogia fundamentada no imperativo categórico que, através da razão crítica, coaduna a esfera do particular com o geral numa mesma disposição, isso tudo, no entanto, sem esquecer o fato de que a razão não deve dispensar um forte exame sobre seus limites e possibilidades, haja vista a preocupação de Kant com o que se refere às fronteiras da própria razão, questão fundamental no período maduro de sua filosofia.
