Published: May 2021

The major aim of the study was to investigate the effects of information seeking behaviour on accessibility of library services by students with visual impairment. The study was carried out at Hamu Mukasa Library of Uganda Christian University in Mukono, Uganda. The study objectives were to weigh the needs of information to Students with Visual Impairment (SWVI) in UCU library, assess information seeking behaviors of SWVI at UCU library, to evaluate the library facilities and services currently available for SWVI, to interrogate the sources of information for SWVI and to analyze the challenges encountered by SWVI while seeking for information at UCU library. The researcher used a descriptive design confirming about the truthfulness of the matter of fact to give wright answers to the research questions in an understandable manner giving the exact picture of what transpires amidst the SWVI while seeking for information from the Library. The study applied the qualitative together with quantitative research methods venturing into and making use of questionnaires and extracting information from the documents. The target population in the study included SWVI and staff at Uganda Christian University (UCU) Hamu Mukasa library. The study targeted the visually impaired students plus library staff members who serve or train information search skills to the students. A sample size of 100 participants was chosen from the total population of 150 whereby sample size of library staff was 60 and a sample of 40 students with visual impairment. The findings revealed that the library staff have inadequacy skills to allow them understand the needs of SWVI and their information seeking behaviours, thus failure to serve SWVI diligently. In regard to this, the study is mandated to air out the services provided, the facilities available and showing how they are insignificant to suite the information requirements of these particular users of the library. The study was well-timed to handle the assessment on effects of information seeking behaviour while accessing library services by (SWVI) at Uganda Christian University. The study recommended to the government, academic libraries, Non-Government Organisations and other agencies serving visually impaired people; to work together on the strategies to improve library facilities and information services for the visually impaired students.

La utilización de arcoterapia volumétrica de intensidad modulada (VMAT) para el tratamiento de cáncer de mama siempre ha sido un asunto controvertido. La mayor conformación de las dosis absorbidas altas que se consigue con la VMAT frente a la radioterapia conformada (3DCRT) viene acompañada de un incremento del volumen irradiado con dosis absorbidas bajas, cuyas consecuencias hay que analizar. El presente estudio pretende, mediante el análisis de las dosimetrías clínicas de 80 pacientes con cáncer de mama tratadas en nuestro centro con ambas técnicas, evaluar la idoneidad de la elección de una técnica frente a la otra para el tratamiento de pacientes con cáncer de mama que precisan la irradiación de cadenas ganglionares axilo-claviculares, pero no de la cadena mamaria interna. Para ello se tienen en cuenta por un lado criterios puramente dosimétricos, como el cumplimiento de los límites de dosis absorbida establecidos en órganos de riesgo, y por otro se realiza una estimación del aumento en la probabilidad de desarrollar tumores secundarios sólidos por la irradiación a baja dosis de órganos sanos y se evalúan las posibles la toxicidades, cardiacas y pulmonares, en base a lo descrito en la literatura.
Shifting attention between modalities: Revisiting the modality-shift effect in autism
Authors: Poole Daniel , Miles Eleanor , Gowen Emma , Poliakoff Ellen 
Published: May 2021

AbstractSelective attention to a sensory modality has been observed experimentally in studies of the modality-shift effect – a relative performance benefit for targets preceded by a target in the same modality, compared to a different modality. Differences in selective attention are commonly observed in autism and we investigated whether exogenous (automatic) shift costs between modalities are increased. Autistic adults and neurotypical controls made speeded discrimination responses to simple visual, tactile and auditory targets. Shift costs were observed for each target modality in participant response times and were largest for auditory targets, reflective of fast responses on auditory repeat trials. Critically, shift costs were similar between the groups. However, integrating speed and accuracy data using drift-diffusion modelling revealed that shift costs in drift rates (reflecting the quality of information extracted from the stimulus) were reduced for autistic participants compared with neurotypicals. It may be that, unlike neurotypicals, there is little difference between attention within and between sensory modalities for autistic people. This finding also highlights the benefit of combining reaction time and accuracy data using decision models to better characterise selective attention in autism.
On the relevance of task instructions for the influence of action on perception
Authors: Kirsch Wladimir 
Published: May 2021

AbstractThe present study explored how task instructions mediate the impact of action on perception. Participants saw a target object while performing finger movements. Then either the size of the target or the size of the adopted finger postures was judged. The target judgment was attracted by the adopted finger posture indicating sensory integration of body-related and visual signals. The magnitude of integration, however, depended on how the task was initially described. It was substantially larger when the experimental instructions indicated that finger movements and the target object relate to the same event than when they suggested that they are unrelated. This outcome highlights the role of causal inference processes in the emergence of action specific influences in perception.
Selective Devaluation Affects the Processing of Preferred Rewards
Authors: Huvermann Dana M. , Bellebaum Christian , Peterburs Jutta 
Published: May 2021

AbstractThe present study investigated whether the representation of subjective preferences in the event-related potential is manipulable through selective devaluation, i.e., the consumption of a specific food item until satiety. Thirty-four participants completed a gambling task in which they chose between virtual doors to find one of three snack items, representing a high, medium, or low preference outcome as defined by individual desire-to-eat ratings. In one of two test sessions, they underwent selective devaluation of the high preference outcome. In the other, they completed the task on an empty stomach. Consistent with previous findings, averaged across sessions, amplitudes were increased for more preferred rewards in the time windows of P2, late FRN, and P300. As hypothesised, we also found a selective devaluation effect for the high preference outcome in the P300 time window, reflected in a decrease in amplitude. The present results provide evidence for modulations of reward processing not only by individual factors, such as subjective preferences, but also by the current motivational state. Importantly, the present data suggest that selective devaluation effects in the P300 may be a promising tool to further characterise altered valuation of food rewards in the context of eating disorders and obesity.
The Color and Brightness of the F-corona Inferred from the 2019 July 2 Total Solar Eclipse
Authors: Boe Benjamin , Habbal Shadia , Downs Cooper , Druckmüller Miloslav 
Published: May 2021

Abstract
Total solar eclipses (TSEs) provide a unique opportunity to quantify the properties of the K-corona (electrons), F-corona (dust), and E-corona (ions) continuously from the solar surface out to a few solar radii. We apply a novel inversion method to separate emission from the K- and F-corona continua using unpolarized total brightness (tB) observations from five 0.5 nm bandpasses acquired during the 2019 July 2 TSE between 529.5 and 788.4 nm. The wavelength dependence relative to the photosphere (i.e., color) of the F-corona itself is used to infer the tB of the K- and F-corona for each line of sight. We compare our K-corona emission results with the Mauna Loa Solar Observatory (MLSO) K-Cor polarized brightness (pB) observations from the day of the eclipse, and the forward modeled K-corona intensity from the Predictive Science Inc. (PSI) magnetohydrodynamic (MHD) model prediction. Our results are generally consistent with previous work and match both the MLSO data and PSI-MHD predictions quite well, supporting the validity of our approach and of the PSI-MHD model. However, we find that the tB of the F-corona is higher than expected in the low corona, perhaps indicating that the F-corona is slightly polarized—challenging the common assumption that the F-corona is entirely unpolarized.

Abstract
The nova rate in the Milky Way remains largely uncertain, despite its vital importance in constraining models of Galactic chemical evolution as well as understanding progenitor channels for Type Ia supernovae. The rate has been previously estimated to be in the range of ≈10–300 yr−1, either based on extrapolations from a handful of very bright optical novae or the nova rates in nearby galaxies; both methods are subject to debatable assumptions. The total discovery rate of optical novae remains much smaller (≈5–10 yr−1) than these estimates, even with the advent of all-sky optical time-domain surveys. Here, we present a systematic sample of 12 spectroscopically confirmed Galactic novae detected in the first 17 months of Palomar Gattini-IR (PGIR), a wide-field near-infrared time-domain survey. Operating in the J band (≈1.2 μm), which is significantly less affected by dust extinction compared to optical bands, the extinction distribution of the PGIR sample is highly skewed to a large extinction values (>50% of events obscured by A

≳ 5 mag). Using recent estimates for the distribution of Galactic mass and dust, we show that the extinction distribution of the PGIR sample is commensurate with dust models. The PGIR extinction distribution is inconsistent with that reported in previous optical searches (null-hypothesis probability <0.01%), suggesting that a large population of highly obscured novae have been systematically missed in previous optical searches. We perform the first quantitative simulation of a 3π time-domain survey to estimate the Galactic nova rate using PGIR, and derive a rate of

A Hard Look at Relativistic Reverberation in MCG-5-23-16 and SWIFT J2127.4+5654: Testing the Lamppost Model
Authors: Zoghbi A. , Miller J. M. , Cackett E. 
Published: May 2021

Abstract
X-ray reverberation mapping has emerged as a new tool to probe accretion in active galactic nuclei (AGN), providing a potentially powerful probe of accretion at the black hole scale. The lags, along with relativistic spectral signatures are often interpreted in light of the lamppost model. Focusing specifically on testing the prediction of the relativistic reverberation model, we have targeted several of the brightest Seyfert Galaxies in X-rays with different observing programs. Here, we report the results from two large campaigns with NuSTAR targeting MCG-5-23-16 and SWIFT J2127.4+5654 to test the model predictions in the 3–50 keV band. These are two of three sources that showed indications of a delayed Compton hump in early data. With triple the previously analyzed exposures, we find no evidence for relativistic reverberation in MCG-5-23-16, and the energy-dependent lags are consistent with a log-linear continuum. In SWIFT J2127.4+5654, although a continuum-only model explains the data, the relativistic reverberation model provides a significant improvement to the energy and frequency-dependent lags, but with parameters that are not consistent with the time-averaged spectrum. This adds to mounting evidence showing that the lag data is not consistent with a static lamppost model.
X-Ray Spectroscopy in the Microcalorimeter Era. III. Line Formation under Case A, Case B, Case C, and Case D in H- and He-like Iron for a Photoionized Cloud

Published: May 2021

Abstract
Future microcalorimeter X-ray observations will resolve spectral features in unmatched detail. Understanding of line formation processes in X-rays deserves much attention. The purpose of this paper is to discuss such processes in the presence of a photoionizing source. Line formation processes in one- and two-electron species are broadly categorized into four cases. Case A occurs when the Lyman line optical depths are very small and photoexcitation does not occur. Line photons escape the cloud without any scattering. Case B occurs when the Lyman line optical depths are large enough for photons to undergo multiple scatterings. Case C occurs when a broadband continuum source strikes an optically thin cloud. The Lyman lines are enhanced by induced radiative excitation of the atoms/ions by continuum photons, also known as continuum pumping. A fourth, less studied scenario, where the Case B spectrum is enhanced by continuum pumping, is called Case D. Here, we establish the mathematical foundation of Cases A, B, C, and D in an irradiated cloud with Cloudy. We also show the total X-ray emission spectrum for all four cases within the energy range 0.1–10 keV at the resolving power of XRISM around 6 keV. Additionally, we show that the combined effect of electron scattering and partial blockage of continuum pumping reduces the resonance line intensities. Such reduction increases with column density and can serve as an important tool to measure the column density/optical depth of the cloud.
The Observability of Plasmoid-powered γ-Ray Flares with the Fermi Large Area Telescope
Authors: Meyer Manuel , Petropoulou Maria , Christie Ian M. 
Published: May 2021

Abstract
The exact mechanism for the production of fast γ-ray variability in blazars remains debated. Magnetic reconnection, in which plasmoids filled with relativistic particles and magnetic fields are formed, is a viable candidate to explain the broadband electromagnetic spectrum and variability of these objects. Using state-of-the-art magnetic reconnection simulations, we generate realistic γ-ray light curves that would be observed with the Fermi Large Area Telescope. A comparison with observed γ-ray flares from flat spectrum radio quasars (FSRQs) reveals that magnetic reconnection events lead to comparable flux levels and variability patterns, in particular, when the reconnection layer is slightly misaligned with the line of sight. Emission from fast plasmoids moving close to the line of sight could explain the fast variability on the timescales of minutes for which evidence has been found in observations of FSRQs. Our results motivate improvements in existing radiative transfer simulations as well as dedicated searches for fast variability as evidence for magnetic reconnection events.
