ABSTRACT
Binary stars in which oscillations can be studied in either or both components can provide powerful constraints on our understanding of stellar physics. The bright binary 12 Boötis (12 Boo) is a particularly promising system because the primary is roughly 60 per cent brighter than the secondary despite being only a few per cent more massive. Both stars have substantial surface convection zones and are therefore, presumably, solar-like oscillators. We report here the first detection of solar-like oscillations and ellipsoidal variations in the TESS light curve of 12 Boo. Though the solar-like oscillations are not clear enough to unambiguously measure individual mode frequencies, we combine global asteroseismic parameters and a precise fit to the spectral energy distribution (SED) to provide new constraints on the properties of the system that are several times more precise than values in the literature. The SED fit alone provides new effective temperatures, luminosities, and radii of $6115\pm 45\, \mathrm{K}$, $7.531\pm 0.110\, \mathrm{L}_\odot$, and $2.450\pm 0.045\, \mathrm{R}_\odot$ for 12 Boo A and $6200\pm 60\, \mathrm{K}$, $4.692\pm 0.095\, \mathrm{L}_\odot$, and $1.901\pm 0.045\, \mathrm{R}_\odot$ for 12 Boo B. When combined with our asteroseismic constraints on 12 Boo A, we obtain an age of $2.67^{+0.12}_{-0.16}\, \mathrm{Gyr}$, which is consistent with that of 12 Boo B.

ABSTRACT
The cosmological nature of gamma-ray bursts (GRBs) implies that a small portion of them could be gravitationally lensed by foreground objects during their propagation. The gravitational lensing effect on the GRB prompt emission and on-axis afterglows has been discussed, and some candidates have been found in the literature. In this work, considering the high detection rate of GRB orphan afterglows in future wide-field survey era, we investigate the gravitationally lensed orphan afterglows in view of three lens models, i.e. the point-mass model, the singular isothermal sphere model, and the Chang–Refsdal model. The structure of the GRB jet itself is also incorporated in calculating the lensed afterglow light curves. It is found that lensed optical/X-ray orphan afterglows in principle could be diagnosed through their temporal characteristics, and the optical band is the best band to observe the galaxy-lensed orphan afterglows. Moreover, the event rate for galaxy-lensed orphan afterglows is estimated to be ≲ 1.8 yr−1 for the whole sky. If most orphan afterglows could be identified (from other transients in the survey data), the optimistic detection rates of the 2.5 m Wide Field Survey Telescope of China and 8.4 m Vera Rubin Observatory Legacy Survey of Space and Time for galaxy-lensed orphan afterglows in the optical band are ≲ 0.01–0.02 and ≲ 0.04–0.08 yr−1, respectively.
The spectral analysis of GRB 150902A and the nature of its outflow
Authors: Nawaz Alina , Sajjad Saeeda 
Published: August 2022

ABSTRACT
The degree of magnetization of the jets remains an important question in Gamma-Ray Burst (GRB) physics. The magnetization at a large distance from the initial radius also determines whether the process for non-thermal prompt emission is magnetic reconnection or internal shocks. In this article, we aim to address these questions for GRB 150902A. We carry out the spectral analysis of GRB 150902A between 8 keV and 100 GeV with the data from the Fermi Gamma-ray SpaceTelescope. In both the time-integrated and time-resolved analyses, we find that the fit of the spectrum is significantly improved by the addition of a sub-dominant black-body component to the Band function. These results allow us to study and constrain the properties of the outflow. In particular, we consider different values of the efficiency of the non-thermal emission process fNT and evaluate possible ranges of the initial fraction of power in thermal form ϵTh for different initial radii. We find that GRB 150902A has a strong magnetic component in the initial outflow, such that ϵTh ≤ 0.5. Small values of the initial radius tend to favour internal shocks; high efficiency magnetic reconnection is completely excluded and relatively low efficiency magnetic reconnection is only possible if the outflow is almost entirely accelerated thermally. For larger initial radii, ϵTh ≪ 0.5 such that the outflow is dominated by the magnetic component initially. Such initial radii allow for the non-thermal emission process to be either magnetic reconnection or internal shocks, depending on the efficiency of the acceleration by the magnetic component.

Abstract
We present the fifth edition of the TimeTree of Life resource (TToL5), a product of the timetree of life project that aims to synthesize published molecular timetrees and make evolutionary knowledge easily accessible to all. Using the TToL5 web portal, users can retrieve published studies and divergence times between species, the timeline of a species’ evolution beginning with the origin of life, and the timetree for a given evolutionary group at the desired taxonomic rank. TToL5 contains divergence time information on 137,306 species, 41% more than the previous edition. The TToL5 web interface is now Americans with Disabilities Act-compliant and mobile-friendly, a result of comprehensive source code refactoring. TToL5 also offers programmatic access to species divergence times and timelines through an application programming interface, which is accessible at timetree.temple.edu/api. TToL5 is publicly available at timetree.org.
Estimating the Impact of COVID-19 on Changes in Volume Sales of Cigars, Smokeless Tobacco Products, Pipe, and Roll-your-own Tobacco in the United States

Published: August 2022

AbstractIntroductionWe examined the potential impact of COVID-19 on trends in volume sales of non-cigarette combustible and smokeless tobacco products in the United States.Aims and MethodsWe analyzed monthly national sales for cigars, smokeless tobacco, pipe, and roll-your-own tobacco during June 2019–June 2021. Data were from the U.S Department of the Treasury. Interrupted time-series were used to measure associations of the COVID-19 “shock” (taken as June 2020 or 6 months after the first diagnosis of COVID-19 in the United States) and volume sales. Negative binomial regression was used to evaluate associations between volume sales and changes in community mobility.ResultsWithin interrupted time-series analysis, the shock of the COVID-19 pandemic was associated with an initial increase in the number of little cigars sold by 11.43 million sticks (p &lt; .01), with no significant sustained change in trend. The COVID-19 shock was also associated with an initial increase in large cigar volume sales by 59.02 million sticks, followed by a subsequent decrease by 32.57 million sticks per month (p = .005). Every 10% reduction in mobility to retail stores was significantly associated with reduced volume sales of little cigars (IRR = 0.84, 95% CI, 0.71 to 0.98) and large cigars (IRR = 0.92, 95% CI, 0.88 to 0.96). Other findings were statistically nonsignificant.ConclusionsCOVID-19 was associated with increased volume sales for cigars and there was a significant association between reduced mobility to points of sale and reduced cigar volume sales. Intensified efforts are needed to prioritize evidence-based tobacco prevention and control efforts amidst the pandemic.

Abstract

Introduction
Whether novelty-flavored vaping devices should be available in the marketplace has been a hotly contested debate. From one perspective, the variety of different flavors, such as fruit and mint, may help adult cigarette smokers who are seeking to switch to reduced-harm nicotine products. However, these flavors are also wildly popular among youth, creating concerns about new nicotine product use among minors.

Aims and Methods
This experiment (n = 176) tests whether vaping flavors (tobacco vs fruit) and flavor representations on packages (flavor color, flavor image) influence how middle school youth perceive vaping products.

Results
While results show no difference in risk perceptions based on condition, novelty perceptions (eg, how fun, interesting) and susceptibility to vaping are highest among those who view the fruit-flavored vaping product with flavor color and flavor image. Those who viewed this condition reported higher novelty perceptions and susceptibility than those who viewed the fruit-flavored vaping product with no flavor color and no flavor image. Additionally, they reported higher novelty perceptions than those who viewed the tobacco-flavored vaping product with flavor color and flavor image. A post-hoc analysis in supplemental data shows that youth who report lower risk perceptions and higher susceptibility have higher behavioral intentions to vape in the next year.

Conclusion
Findings suggest that restricting flavor representation on packaging might reduce how fun and interesting youth perceive these products to be and how susceptible they are to using them.
Antibody response to an accelerated course of Hepatitis B vaccination
Authors: Lian P C S , Morrish B 
Published: August 2022

Abstract

Background
There are several courses with different dosing intervals for Hepatitis B vaccination. This independent study is looking at the antibody response after three doses of the accelerated course.

Aims
The primary aim of the study was to examine data available at an Occupational Health Service for the antibody response to one or if nonresponsive, two accelerated Hepatitis B courses. A secondary aim is to determine if there is a difference in response for different sex and age groups.

Methods
This is a retrospective anonymous and blinded study looking at the antibody response in 1032 healthcare personnel given the accelerated course of the Hepatitis B vaccine over a period of over 6 years. An anti-Hbs response 4 months after the start of the vaccination of &gt;10 IU/ml was taken as indicative of a response.

Results
After one course, 93% of the healthcare personnel developed antibody levels thought to confer immunity. After two courses, nearly 99% of the healthcare personnel had developed an adequate immune response. The response was better in females and &lt;40 years old, a difference that was statistically significant for those aged &lt;40.

Conclusions
The accelerated course confers high levels of immunity after 4 months and this supports the current practice of offering the accelerated dose to UK healthcare personnel who can be at immediate and higher risk of infection. Though some groups are less responsive, all groups mount a good response so all those at risk should be encouraged to have this vaccination.

Authors: Perečinský S , Murínová L , Tomčová J , Poľanová M , Legáth Ľ 
Published: August 2022

Abstract

Background
Outbreaks of hypersensitivity pneumonitis (HP) are not uncommon in workplaces where metalworking fluids (MWFs) are used. The recirculation of MWFs leads to microbiological contamination, which is responsible for outbreaks. Most outbreak reports come from USA and the UK; however, no similar reports have been published from Central Europe.

Aims
To describe an outbreak of MWF-associated HP in workers from a compressor assembly manufacturing facility in Slovak Republic and to identify the potential antigens responsible for the outbreak.

Methods
We investigated the history of worker’s symptoms, physical examinations, lung function tests, radiographic scans and lung biopsies. The MWF samples were analysed for different strains of bacteria and fungi. Antigen extracts were produced from the microorganisms isolated from MWFs, and positive precipitin reactions were evaluated.

Results
MWF-associated HP was diagnosed in 21 men and 6 women. All workers had work-related dyspnoea and cough with abnormal pulmonary diffusing capacity. Twenty-four cases had evidence of interstitial lung disease. Four cases were classified as having fibrotic HP. Nineteen microbial isolates (12 bacteria and 7 fungi) were cultured from the MWFs. Twenty-five cases had a positive response to at least one isolate. Eikenella corrodens and Bacillus subtilis were the most frequently reacting antigens (in 15 and 12 workers, respectively).

Conclusions
Despite decreasing reports of MWF-associated HP outbreaks over the past several decades, we describe one of the largest outbreaks in Europe. While the bacterium E. corrodens was found in the MWF samples, its relationship to the disease should be further investigated.
Acute respiratory distress after exposure to chlorine dioxide-based disinfectant
Authors: Hassel Erlend , Smedbold Hans Thore , Lauritzen Hilde Brun 
Published: August 2022

Abstract
A hospital cleaner developed acute respiratory distress after working with a chlorine dioxide-based disinfectant. The content of chlorine dioxide in the product is below the limit that would require the product to be labelled as hazardous to health, but we show with a simple estimation that the relevant threshold limit values for chlorine dioxide in the working atmosphere may be exceeded under normal use of the product. This may have implications for risk assessment of the use of such chlorine dioxide-based disinfectants and may warrant stricter regulations for labelling these products.
Changes in Quality of Sleep, Mood, and Other Neuropsychiatric Symptoms After Switching Dolutegravir/Lamivudine/Abacavir to Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide in a Randomized Study of People With Human Immunodeficiency Virus With Poor Sleep Quality: GESIDA 10418

Abstract

Background
Although switching antiretroviral therapy (ART) in people with human immunodeficiency virus experiencing insomnia due to dolutegravir-related neurotoxicity is well founded upon evidence, there is a lack of proof in regard to the outcome of stopping dolutegravir-based ART in people without insomnia but reporting poor sleep quality.

Methods
This is a randomized, multicenter, open-label study to evaluate the reversibility of patient-reported sleep disturbances in patients on dolutegravir/lamivudine/abacavir without insomnia after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. The participants were randomized to switch ART at baseline or at week 4 and then completed 8 weeks of darunavir/cobicistat/emtricitabine/tenofovir alafenamide. Our primary objective was to compare changes in sleep quality between arms at week 4. Secondary objectives were to compare changes in mood and neuropsychiatric symptoms (NS) at week 4 and 4 and 8 weeks after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. The participants completed a survey, including the Pittsburgh Sleep Quality Index (PSQI), the Hospital Anxiety and Depression scale (HADS), and specific questions to explore NS, at each visit to assess those objectives.

Results
We included 72 participants. The results show that study arms were similar at baseline; however, at week 4, PSQI scores remained unchanged with dolutegravir/lamivudine/abacavir, whereas patients improved significantly after switching to darunavir/cobicistat/emtricitabine/tenofovir alafenamide. Similar differences between arms were also observed in HADS and NS changes. At weeks 4 and 8 after all participants switched to darunavir/cobicistat/emtricitabine/tenofovir alafenamide, we have observed significant improvements in PSQI and HAD scores and in NS.

Conclusions
In patients reporting subclinical sleep disturbances without insomnia, switching from dolutegravir/lamivudine/abacavir to darunavir/cobicistat/emtricitabine/tenofovir alafenamide was associated with better sleep quality and improvements in mood and NS.
Social Satisfaction and Living Alone: Predictors of Self-Perception of Mental Health Improvement After Psychosis
Authors: Turner Patricia R , Saeteurn Emily R 
Published: August 2022

Abstract

Background
Psychosis recovery can accompany social and self-stigma for the survivor, which can interfere with the person reaching their personal recovery goals. We hypothesized that there would be a strong association between social satisfaction and self-perceived mental health improvement, and that living alone would be a risk factor to self-perceived improvement.

Study Design
Our strengths-based quantitative study aims to identify the most important factors to psychosis survivors for their mental health recovery. Survey responses from wave 5 of the Population Assessment of Tobacco and Health (PATH) study were used, specifically from those who self-identified as psychosis survivors (n = 710), analyzing the association between self-reported mental health symptoms, social satisfaction changes in the last year, living alone, and demographic variables, with self-reported mental health recovery in the last year.

Study Results
Ordinary least squares regression analysis revealed three predictors of self-reported mental health improvement for psychosis survivors: social satisfaction, living alone, and lower anxiety. As hypothesized, social satisfaction was the largest determinant in self-perceived mental health improvement, but contrary to our hypothesis, living alone was a protective factor.

Conclusion
Prioritizing social satisfaction over group living environments for people recovering after psychosis.
Academics’ prosocial motivation for engagement with society: The case of German academics in health science
Authors: Sormani E , Uude K 
Published: August 2022

Abstract
Although research has shown the importance of prosocial motivation for academic engagement in public good (universities’ so-called ‘third mission’), research is yet to examine such motivation in depth. This study develops an empirical understanding of the dimensions of prosocial motivation in academics’ engagement, focusing particularly on societal engagement. Self-determination theory and conceptual forms of prosocial motivation (principlism, egoism, collectivism, and altruism) assist in interpreting the dimensions. We conducted twenty-five qualitative interviews with academics in the field of health science in Germany. Three dimensions of prosocial motivation emerged from the data: (1) personal, (2) academic role, and (3) academic field. The results demonstrate how the various conceptual forms of prosocial motivation are reflected in these dimensions. Additionally, we advance our understanding of how intrinsic and extrinsic elements are reflected in academics’ prosocial motivation. We offer important theoretical, managerial, and policy implications by significantly improving the understanding of academics’ prosocial motivation.
Dynamic models of obstructive sleep apnea provide robust prediction of respiratory event timing and a statistical framework for phenotype exploration
Authors: Chen Shuqiang , Redline Susan , Eden Uri T , Prerau Michael J 
Published: August 2022

AbstractObstructive sleep apnea (OSA), in which breathing is reduced or ceased during sleep, affects at least 10% of the population and is associated with numerous comorbidities. Current clinical diagnostic approaches characterize severity and treatment eligibility using the average respiratory event rate over total sleep time (apnea-hypopnea index). This approach, however, does not characterize the time-varying and dynamic properties of respiratory events that can change as a function of body position, sleep stage, and previous respiratory event activity. Here, we develop a statistical model framework based on point process theory that characterizes the relative influences of all these factors on the moment-to-moment rate of event occurrence. Our results provide new insights into the temporal dynamics of respiratory events, suggesting that most adults have a characteristic event pattern that involves a period of normal breathing followed by a period of increased probability of respiratory event occurrence, while significant differences in event patterns are observed among gender, age, and race/ethnicity groups. Statistical goodness-of-fit analysis suggests consistent and substantial improvements in our ability to capture the timing of individual respiratory events using our modeling framework. Overall, we demonstrate a more statistically robust approach to characterizing sleep disordered breathing that can also serve as a basis for identifying future patient-specific respiratory phenotypes, providing an improved pathway towards developing individualized treatments.

Abstract
In response to social distancing measures during the COVID-19 pandemic, there was a need to increase the frequency of internet enabled behaviors (IEBs). To date, little is known about how the pandemic impacted IEBs in older adults, a population that has historically been linked to lower digital literacy and utilization. We administered an online survey between April and July 2021 to 298 adults who were over age 50 (mean age = 73 years; 93.5% non-Hispanic white; 94% smart phone owners; 83.5% retired). Older adults self-reported IEBs for social, shopping, medical, and leisure activities during the pandemic, plans for continued use of these behaviors, and completed measures of psychosocial functioning. 66.8% of respondents reported an overall increase in IEBs during the pandemic, most notably for online meeting attendance. More frequent online meeting use was associated with less depression (r = −0.12, p = .04) and less loneliness (r = −0.14, p = .02). With regard to plans for continued use, 82.5% of the sample reported at least one IEB (M = 2.18, SD = 1.65) that they increased during the pandemic and planned to maintain over time (e.g., online shopping for household goods). Plans for continued use were more likely in participants who used IEBs more overall during the pandemic (r = 0.56, p &lt; .001), and who frequently sought technical support on search engines (r = 0.22, p &lt; .001), or online video sites (r = 0.16, p = .006). In summary, IEBs during the pandemic were associated with favorable psychosocial functioning and expectations for continued use in this sample of predominantly white older adults who had some baseline technological familiarity.
