Transient attention does not alter the eccentricity effect in estimation of duration

Published: August 2023

AbstractPrevious research investigating the influence of stimulus eccentricity on perceived duration showed an increasing duration underestimation with increasing eccentricity. Based on studies showing that precueing the stimulus location prolongs perceived duration, one might assume that this eccentricity effect is influenced by spatial attention. In the present study, we assessed the influence of transient covert attention on the eccentricity effect in duration estimation in two experiments, one online and one in a laboratory setting. In a duration estimation task, participants judged whether a comparison stimulus presented near or far from fixation with a varying duration was shorter or longer than a standard stimulus presented foveally with a constant duration. To manipulate transient covert attention, either a transient luminance cue was used (valid cue) to direct attention to the position of the subsequent peripheral comparison stimulus or all positions were marked by luminance (neutral cue). Results of both experiments yielded a greater underestimation of duration for the far than for the near stimulus, replicating the eccentricity effect. Although cueing was effective (i.e., shorter response latencies for validly cued stimuli), cueing did not alter the eccentricity effect on estimation of duration. This indicates that cueing leads to covert attentional shifts but does not account for the eccentricity effect in perceived duration.

AbstractOver the past few decades, there have been significant developments in eye-tracking technology, particularly in the domain of mobile, head-mounted devices. Nevertheless, questions remain regarding the accuracy of these eye-trackers during static and dynamic tasks. In light of this, we evaluated the performance of two widely used devices: Tobii Pro Glasses 2 and Tobii Pro Glasses 3. A total of 36 participants engaged in tasks under three dynamicity conditions. In the “seated with a chinrest” trial, only the eyes could be moved; in the “seated without a chinrest” trial, both the head and the eyes were free to move; and during the walking trial, participants walked along a straight path. During the seated trials, participants’ gaze was directed towards dots on a wall by means of audio instructions, whereas in the walking trial, participants maintained their gaze on a bullseye while walking towards it. Eye-tracker accuracy was determined using computer vision techniques to identify the target within the scene camera image. The findings showed that Tobii 3 outperformed Tobii 2 in terms of accuracy during the walking trials. Moreover, the results suggest that employing a chinrest in the case of head-mounted eye-trackers is counterproductive, as it necessitates larger eye eccentricities for target fixation, thereby compromising accuracy compared to not using a chinrest, which allows for head movement. Lastly, it was found that participants who reported higher workload demonstrated poorer eye-tracking accuracy. The current findings may be useful in the design of experiments that involve head-mounted eye-trackers.

Abstract
We present the analysis of 510 light curves in V and I bands of 255 giant stars in the globular cluster NGC 3201. Our aim is to expand the sample of new types of variables reported in a previous study. These variables show a short period (P

V
< 0.6 day) and a low amplitude (A(V) < 0.06 mag.). We first searched for variability using the generalized Lomb–Scargle and phase dispersion minimization periodograms of the sample, discarding 167 stars as non-variables. We then applied the significance test and reduced the sample to 88 giants, of which we classified 18 as possible variables, 11 as dubious, 41 as non-variables, and 18 as variables. We finally determined the cluster membership of this sample and grouped each star based on their light-curve shape. The discovered variables show periods in the range 0.2440 < P

V
< 0.5868 days and amplitudes between 0.010 < A(V) < 0.064 mag. Within the sample of 18 variable stars, we report the discovery of an object with a period P

V
= 0.3603 ± 0.0012 and amplitude A(V) = 0.703 ± 0.029 mag that shows a RR Lyrae ab-type light curve. Additionally, we report two RR Lyrae ab and c types with ultralow amplitude.

AbstractWe present the optical photometric and spectroscopic analysis of two Type Iax supernovae (SNe), 2018cni and 2020kyg. SN 2018cni is a bright Type Iax SN (MV,peak= −17.81 ± 0.21 mag), whereas SN 2020kyg (MV,peak= −14.52 ± 0.21 mag) is a faint one. We derive56Ni mass of 0.07 and 0.002M⊙and ejecta mass of 0.48 and 0.14M⊙for SNe 2018cni and 2020kyg, respectively. A combined study of the bright and faint Type Iax SNe inR/r-band reveals that the brighter objects tend to have a longer rise time. However, the correlation between the peak luminosity and decline rate shows that bright and faint Type Iax SNe exhibit distinct behavior. Comparison with standard deflagration models suggests that SN 2018cni is consistent with the deflagration of a CO white dwarf, whereas the properties of SN 2020kyg can be better explained by the deflagration of a hybrid CONe white dwarf. The spectral features of both the SNe point to the presence of similar chemical species but with different mass fractions. Our spectral modeling indicates stratification at the outer layers and mixed inner ejecta for both of the SNe.

Published: August 2023

Abstract
Dust particle sizes constrained from dust continuum and polarization observations by radio interferometry are inconsistent by at least an order of magnitude. Motivated by porous dust observed in small solar system bodies (e.g., from the Rosetta mission), we explore how the dust particle’s porosity affects the estimated particle sizes from these two methods. Porous particles have lower refractive indices, which affect both opacity and polarization fraction. With weaker Mie interference patterns, the porous particles have lower opacity at millimeter wavelengths than the compact particles if the particle size exceeds several hundred microns. Consequently, the inferred dust mass using porous particles can be up to a factor of six higher. The most significant difference between compact and porous particles is their scattering properties. The porous particles have a wider range of particle sizes with high linear polarization from dust self-scattering, allowing millimeter- to centimeter-sized particles to explain polarization observations. With a Bayesian approach, we use porous particles to fit HL Tau disk’s multiwavelength continuum and millimeter-polarization observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and the Very Large Array (VLA). The moderately porous particles with sizes from 1 mm–1 m can explain both continuum and polarization observations, especially in the region between 20 and 60 au. If the particles in HL Tau are porous, the porosity should be from 70%–97% from current polarization observations. We also predict that future observations of the self-scattering linear polarization at longer wavelengths (e.g., ALMA B1 and ngVLA) have the potential to further constrain the particle’s porosity and size.

Abstract
Interactions and mergers play an important role in regulating the physical properties of galaxies, such as their morphology, gas content, and star formation rate (SFR). Controversy exists as to the degree to which these events, even gas-rich major mergers, enhance star formation activity. We study merger pairs selected from a sample of massive (M

The dust masses, when converted to equivalent total atomic and molecular hydrogen, probe gas masses as low as ∼108.5

* plane: the gas-rich, star-forming galaxies that trace the well-studied gas mass main sequence, and passive galaxies that occupy a distinct, gas-poor regime. These two populations, in turn, map into a bimodal distribution on the relation between SFR and gas mass surface density. Among low-redshift galaxies, galaxy mergers, including those that involve gas-rich and nearly equal-mass galaxies, exert a minimal impact on their SFR, specific SFR, or star formation efficiency. Starbursts are rare. The star formation efficiency of gas-rich, minor mergers even appears suppressed. This study stresses the multiple, complex factors that influence the evolution of the gas and its ability to form stars in mergers.
Formation of the Injection Function of Solar Energetic Particles in Gradual Events
Authors: Petukhov Ivan , Petukhova Anastasia , Petukhov Stanislav 
Published: August 2023

Abstract
We present a model for solar energetic particle injection into interplanetary space in gradual events, in which particle acceleration occurs in a limited region of the solar atmosphere. The distribution function of particles accelerated by the diffusion mechanism is calculated. The flux of injected solar energetic particles is determined as a function of time and energy. We provide an explanation of the characteristic properties of the injection function and their dependence on the particle energy. Comparing the calculation results with ground-based measurements in the 2001 April 15 event shows a rough agreement with the particle density as a function of time and good agreement with the spectrum of maximum intensity values.

Published: August 2023

Abstract
Planets close to their stars experience an interplanetary magnetic field (IMF) that is dominantly quasi-radial. Our solar system serves as a laboratory to study how the occurrence of quasi-radial IMF varies away from the star and under different stellar activities. Furthermore, on time and spatial scales relevant to magnetospheric physics, solar wind variability prevails in the form of structures generated both at the Sun and locally in the interplanetary space. The stationary Parker spiral model only approximates the large-scale structure of the IMF. Deviations from the Parker spiral often result in strongly radial magnetic fields that give rise to kinetic foreshock turbulence, which in turn can impact planetary magnetospheres. The relative significance of this type of interaction can be estimated statistically based on the occurrence rate of cases where the IMF is directed along the radial direction, leading to the entire day-side magnetosphere being downstream of the ion foreshock. We use observations covering radial distances from 0.1 to 10 au and more than 2 solar cycles to quantify the prevalence of radial IMFs throughout the heliosphere. Near Earth’s orbit, it is found that the occurrence rates of quasi-radial and southward IMF orientations are similar, and that the Pearson correlation coefficient is

Abstract
The NASA Double Asteroid Redirection Test (DART) spacecraft successfully crashed on Dimorphos, the secondary component of the binary (65803) Didymos system. Following the impact, a large dust cloud was released, and a long-lasting dust tail developed. We have extensively monitored the dust tail from the ground and the Hubble Space Telescope. We provide a characterization of the ejecta dust properties, i.e., particle size distribution and ejection speeds, ejection geometric parameters, and mass, by combining both observational data sets and using Monte Carlo models of the observed dust tail. The size distribution function that best fits the imaging data is a broken power law having a power index of –2.5 for particles of r ≤ 3 mm and –3.7 for larger particles. The particles range in size from 1 μm up to 5 cm. The ejecta is characterized by two components, depending on velocity and ejection direction. The northern component of the double tail, observed since 2022 October 8, might be associated with a secondary ejection event from impacting debris on Didymos, although is also possible that this feature results from the binary system dynamics alone. The lower limit to the total dust mass ejected is estimated at ∼6 × 106 kg, half of this mass being ejected to interplanetary space.

BACKGROUND: Sepsis is a dysregulated host response to infection resulting in potentially life-threatening organ dysfunction. Elevation in red cell distribution width (RDW), a simple routinely done investigation, could be a prognostic marker in these patients.
AIM: We performed this prospective observational study to assess role of dynamic variation of RDW in predicting 30-day mortality in patients with sepsis or septic shock presenting and getting admitted in intensive care unit (ICU) in Fayoum, Egypt.
METHODS: Between January 2019 and January 2021, 150 patients with sepsis or septic shock at admission were prospectively evaluated for association between RDW value on admission, on day 4, on day 7, and 30-day mortality. To find out factors associated independently with 30-day mortality, we applied multivariate logistic regression analysis and used the analysis to develop nanogram for prediction of mortality on admission.
RESULTS: Among 150 patients, 89 (59.3%) were male. Mean age of the patients was 59.6 ± 12.28 years. Regarding RDW on admission (RDW-0), the mean was 14.1 ± 1.9 while on day 4 (RDW-4), the mean was 14.5 ± 1.97, and on day 7 (RDW-7), the mean was 14.4 ± 2.03. Seventy-four (49.3%) patients died during the period of 30 days follow-up. Multiple logistic regression models for the parameters associated with the mortality outcome at admission were done, for age, higher age was associated with higher probability of mortality, OR = 1.07 (95% CI: 1.02, 1.13). Male sex was associated with lower probability of mortality as compared to females, OR = 0.02 (95% CI: 0.06, 0.80). Higher acute physiologic assessment and chronic health evaluation (APACHE) II score, RDW value, and procalcitonin level, all were associated with higher mortality probability. For APACHE II score, higher level was associated with higher odds of mortality, OR = 1.16. For RDW value on admission, higher value was associated with higher odds of mortality, OR = 1.66. For procalcitonin level at admission, higher level was associated with higher odds of mortality, OR = 1.54. Odds for mortality for those who showed any increase in RDW in day 4 as compared to day 0 are higher as compared to those who showed a decrease or no change in RDW, OR = 2.8, p-value = 0.007.
CONCLUSIONS: We found that an increase in RDW value on admission and on day 4 is significantly associated with mortality. And that, an increase in RDW value from day 0 to day 4 is also significantly associated with mortality Therefore, a combination of baseline RDW value and an increase in serial RDW values can be a promising independent prognostic marker in patients with sepsis or septic shock.
Assessment of pharmacy students’ awareness and knowledge of the COVID-19 pandemic and vaccines in Jordan: A cross-sectional study at private universities
Authors: Salama Ali 
Published: August 2023

Introduction: The COVID-19 pandemic prompted a global effort in developing vaccines to combat the virus. While several COVID-19 vaccines have been authorized and distributed internationally, there is a lack of research on the knowledge and perceptions of pharmacy students regarding these vaccines in Jordan.
Methods: A cross-sectional study was conducted among pharmacy students at a private university in Jordan from July 28 to August 5, 2022. A Google survey consisting of 12 questions was administered to 200 respondents.
Results: The survey aimed to assess pharmacy students’ understanding of COVID-19 clinical characteristics, transmission routes, precautionary measures, hazard control, and knowledge of the different types of COVID-19 vaccines available in Jordan. Literature review indicated that students primarily obtained information from social media (80%), written articles (20%), and television (10%). The overall score for students’ awareness of COVID-19 and its vaccines was 85%. The majority of students (82%) demonstrated a high level of knowledge and awareness of the pandemic. However, their understanding of hypercoagulation as an adverse event of COVID-19 vaccination and mask-wearing practices in various settings was limited. Most students believed that effective immunization strategies could eradicate the virus.
Conclusion: Our findings indicate that pharmacy students possess a good understanding of COVID-19 and its vaccines. To enhance infection prevention among future pharmacists, measures and public awareness campaigns should be implemented to promote knowledge about the benefits of immunization in combating the COVID-19 pandemic.

Abstract
Native aquatic species are in decline, and hatcheries can play an important role in stemming these losses until larger ecological issues are addressed. However, as more federal and state agencies face budget uncertainty and the number of imperiled species increases, it is necessary to develop a tool to prioritize species for conservation propagation. Our objective was to create prioritized lists of aquatic species that may benefit from conservation propagation for five states in the United States. Biologists developed an influence diagram and provided information for multiple attributes affecting prevalence of species. The influence diagram and information for each species was used in a Bayesian belief network to generate a score to prioritize propagation of a species and the feasibility of propagation. When all taxa were ranked together within a state, mussels, amphibians, and a crustacean were included among fishes in the top species that may benefit from propagation. We recognize that propagation is one tool for conservation of imperiled species and that additional factors will need to be addressed to ensure species persistence. Nevertheless, we contend our quantitative approach provides a useful framework for prioritizing conservation propagation.
