ABSTRACT
Single dish observations of NGC 1068 have shown the presence of a 3.4 μm aliphatic hydrocarbon absorption feature similar to diffuse lines of sight towards the Galactic Centre. Both, the single dish spectra and the correlated fluxes obtained by MATISSE, present a broad absorption profile in the L band as well, that vary from baseline to baseline. A new CRIRES spectrum with a slit width comparable to the MATISSE aperture also reveals a wide feature around 3.4 μm. We aim to analyse these features to learn about their origin and the distribution of the carriers across the source. We argue that all these features are caused by absorption of aliphatic hydrocarbons. The 3.4 μm absorption features in the interferometric MATISSE correlated fluxes vary in optical depth over scales of 0.2-1.4 parsec in the plane of the sky, although probably placed at a larger distance from the AGN along the line of sight. The absorption in the extended areas seems to peak in the direction of the inner jet, close to the center of the ionization cone. These results support the theory of a clumpy torus. In comparing our results to the N-band surface density previously reported, we have discovered a mass ratio of carbonaceous to silicate olivine dust at ∼2 - 3.6 per cent, which is similar to those found in several lines of sight in the diffuse interstellar medium of our Galaxy.
Cosmic-ray driven galactic winds from the warm interstellar medium

Published: July 2023

ABSTRACT
We study the properties of cosmic-ray (CR) driven galactic winds from the warm interstellar medium using idealized spherically symmetric time-dependent simulations. The key ingredients in the model are radiative cooling and CR-streaming-mediated heating of the gas. Cooling and CR heating balance near the base of the wind, but this equilibrium is thermally unstable, leading to a multiphase wind with large fluctuations in density and temperature. In most of our simulations, the heating eventually overwhelms cooling, leading to a rapid increase in temperature and a thermally driven wind; the exception to this is in galaxies with the shallowest potentials, which produce nearly isothermal $T \approx 10^4\,$ K winds driven by CR pressure. Many of the time-averaged wind solutions found here have a remarkable critical point structure, with two critical points. Scaled to real galaxies, we find mass outflow rates $\dot{M}$ somewhat larger than the observed star-formation rate in low-mass galaxies, and an approximately ‘energy-like’ scaling $\dot{M} \propto v_{\rm esc}^{-2}$. The winds accelerate slowly and reach asymptotic wind speeds of only ∼0.4vesc. The total wind power is $\sim 1~{{\ \rm per\ cent}}$ of the power from supernovae, suggesting inefficient preventive CR feedback for the physical conditions modelled here. We predict significant spatially extended emission and absorption lines from 104–105.5 K gas; this may correspond to extraplanar diffuse ionized gas seen in star-forming galaxies.
Relation between photometric and parameter errors of star clusters
Authors: Li Zhongmu , Liu Xuejie 
Published: July 2023

ABSTRACT
Many observations supply only photometry data with large uncertainties. The study of star clusters based on such data is important for astrophysical studies, although photometric uncertainty affects the accuracy of results. In order to estimate the parameter uncertainties that are caused by photometric errors, this work quantifies the influence of photometric error on the uncertainties of some basic parameters when colour-magnitude diagram (CMD) fitting is used to determine these parameters. The observed data are derived from Hubble Space Telescope (HST) observations with the WFPC2 in four bands because of the large coverage of photometric error. The photometric errors that are estimated by Artificial Star Test (AST) are taken, and a binary star stellar population synthesis model and the Powerful CMD code are adopted to determine the parameters of star clusters. Two popular types of stellar population models, i.e. binary star simple stellar population (bsSSP) and single star simple stellar population (ssSSP), are used. The effects of photometric errors on the uncertainties of distance modulus (m − M), colour excess (E), metallicity (Z), and age (t), i.e. Δm − M, ΔE, ΔZ, and Δt, are studied via 19 globular clusters. The results show that Δm − M, ΔE, ΔZ, and Δt have positive correlations with photometric error. Some linear fitting formulae are given to make the results easy to use. The results can be used to estimate the errors of parameters that are caused by photometric error when determining the parameters by CMD fitting, for star clusters with relatively large photometric uncertainties (&gt;∼0.01 mag).
Constraints on the Galactic centre environment from Gaia hypervelocity stars III: insights on a possible companion to Sgr A*
Authors: Evans F A , Rasskazov A , Remmelzwaal A , Marchetti T , Castro-Ginard A , Rossi E M , Bovy J 
Published: July 2023

ABSTRACT
We consider a scenario in which Sgr A* is in a massive black hole binary (MBHB) with an as-of-yet undetected supermassive or intermediate-mass black hole companion. Dynamical encounters between this MBHB and single stars in its immediate vicinity would eject hypervelocity stars (HVSs) with velocities beyond the Galactic escape velocity of the Galaxy. In this work, we use existing HVS observations to constrain for the first time the existence of a companion to Sgr A*. We simulate the ejection of HVSs via the ‘MBHB slingshot’ scenario and show that the population of HVSs detectable today depends strongly on the companion mass and the separation of the MBHB. We demonstrate that the lack of uncontroversial HVS candidates in Gaia Data Release 3 places a firm upper limit on the mass of a possible Sgr A* companion. Within one milliparsec of Sgr A*, our results exclude a companion more massive than $2000 \, \mathrm{M_\odot }$. If Sgr A* recently merged with a companion black hole, our findings indicate that unless this companion was less massive than $500 \, \mathrm{M_\odot }$, this merger must have occurred at least 10 Myr ago. These results complement and improve upon existing independent constraints on a companion to Sgr A* and show that large regions of its parameter space can now be ruled out.
A variable corona during the transition from type-C to type-B quasi-periodic oscillations in the black hole X-ray binary MAXI J1820+070

ABSTRACT
We analyse a Neutron Star Interior Composition Explorer observation of the black hole X-ray binary MAXI J1820+070 during a transition from type-C to type-B quasi-periodic oscillations (QPOs). We find that below ∼2 keV, for the type-B QPOs the rms amplitude is lower and the magnitude of the phase lags is larger than for the type-C QPOs. Above that energy, the rms and phase-lag spectra of the type-B and type-C QPOs are consistent with being the same. We perform a joint fit of the time-averaged spectra of the source, and the rms and phase-lag spectra of the QPOs with the time-dependent Comptonization model vkompth to study the geometry of the corona during the transition. We find that the data can be well fitted with a model consisting of a small and a large corona that are physically connected. The sizes of the small and large coronae increase gradually during the type-C QPO phase whereas they decrease abruptly at the transition to type-B QPO. At the same time, the inner radius of the disc moves inward at the QPO transition. Combined with simultaneous radio observations showing that discrete jet ejections happen around the time of the QPO transition, we propose that a corona that expands horizontally during the type-C QPO phase, from ∼104 km ($\sim 800\, R_{\rm g}$) to 105 km ($\sim 8000\, R_{\rm g}$) overlying the accretion disc, transforms into a vertical jet-like corona extending over ∼104 km ($\sim 800\, R_{\rm g}$) during the type-B QPO phase.
Measuring tidal dissipation in giant planets from tidal circularization
Authors: Mahmud Mohammad M , Penev Kaloyan M , Schussler Joshua A 
Published: July 2023

ABSTRACT
In this project, we determined the constraints on the modified tidal quality factor, $Q_{\rm pl}^{\prime }$, of gas-giant planets orbiting close to their host stars. We allowed $Q_{\rm pl}^{\prime }$ to depend on tidal frequency, accounting for the multiple tidal waves with time-dependent frequencies simultaneously present on the planet. We performed our analysis on 78 single-star and single-planet systems, with giant planets and host stars with radiative cores and convective outer shells. We extracted constraints on the frequency-dependent $Q_{\rm pl}^{\prime }$ for each system separately and combined them to find general constraints on $Q_{\rm pl}^{\prime }$ required to explain the observed eccentricity envelope while simultaneously allowing the observed eccentricities of all systems to survive to the present-day. Individual systems do not place tight constraints on $Q_{\rm pl}^{\prime }$. However, since similar planets must have similar tidal dissipation, we require that a consistent, possibly frequency-dependent, model must apply. Under that assumption, we find that the value of $\log _{10}Q_{\rm pl}^{\prime }$ for HJs is 5.0 ± 0.5 for the range of tidal period from 0.8 to 7 d. We did not see any clear sign of frequency dependence of $Q_{\rm pl}^{\prime }$.
Development and validation of a clinical model for predicting the severity of carpal tunnel syndrome
Authors: Aalaie Behnaz , Sadeghi Javad , Mohammadi Tanya , Mohammadi Babak 
Published: July 2023

ABSTRACT

Objectives
To develop a clinical instrument to assess carpal tunnel syndrome (CTS) severity before electrodiagnostic testing.

Methods
Data from 1037 patients with CTS (39.1% male) were included. The mean (SD) age was 58.0 (10.8) years. The severity of CTS was based on electrodiagnostic findings.

Results
We devised a composite index incorporating a pain numeric rating scale (NRS) rated from 0 (no pain at all) to 10 (the worst pain ever possible), thenar muscle weakness or atrophy (TW), cross-sectional area (CSA) of the median nerve (mm2), and nocturnal pain (NP). The index was calculated as [scale(NRS)+scale(CSA)+NP+TW]/4, where NP and TW are binary features (0 or 1). The accuracy and area under the curve of the index were 0.85 and 0.71, respectively (Cohen’s Kappa = 0.51, McNemar’s test P = 0.249). The index increased pretest probabilities by 1.6, 1.8, and 3.3 times with positive likelihood ratios of 3.3, 2.5, and 13.5, and false-positive rates of 26.6, 17.6, and 4.8% for mild, moderate, and severe CTS, respectively. The index thresholds for mild, moderate, and severe CTS were &lt;0.8, ≥0.8 to &lt;1.1, and ≥1.1, respectively.

Conclusion
Using a composite index, patients with CTS can be categorized for the severity of the syndrome.
Survey of Premium Versus Large Manufactured Cigars Use in U.S. Consumers
Authors: Smith Carson , Hiteman Kristin , Triplett Cheryl , Pickworth Wallace B 
Published: July 2023

Abstract

Introduction
An Internet questionnaire was used to determine smoking behavior, purchasing behavior, and risk perceptions among exclusive or nearly exclusive current users of either large manufactured (LMC) or premium cigars (PC).

Aims and Methods
Respondents (n = 250) were recruited from a nationally representative market research panel. An a priori designation of PC users was adapted from criteria in published literature and the recent National Academy of Science report.

Results
Examination of responses revealed a (n = 19) disagreement between cigar users’ self-classifications and the a priori classification. After eliminating ineligible respondents 188 participants were classified as PC (n = 92; 55 male) or LMC (n = 96; 49 male) users. There were no significant differences in age or gender between groups. Respondents were all over 21 years old. The largest age groups were 30–39 years and 60–69 years. PC users were significantly more likely to have higher annual incomes and to buy cigars online or through tobacco specialty shops, whereas LMC users purchased from convenience stores. Most participants had used other combustible tobacco products (88%) but few had used ENDS (24%) or oral tobacco (7.5%). There was no significant difference in the frequency of smoke inhalation or perceptions of risk for health. There was marked uncertainty in self-characterization of cigar type; our sample had higher female representation than expected (n = 84, 45%), and inhalation was frequently endorsed in both groups (52%, overall).

Conclusions
The results support the need for standardized classifications and suggest current trends may indicate shifts in gender and use behavior but provide no evidence supporting less restrictive regulation of PC.

Implications
An Internet questionnaire was used to determine smoking behavior, purchasing behavior, and risk perceptions among current users of LMC or PC. There was uncertainty about cigar classification even in this sample of regular users. Our results demonstrated more than expected inhalation of cigar smoke, considerable use by females, and under appreciation of health risks. No results supported less restrictive regulations for premium cigars.

Abstract

Introduction
Understanding the characteristics of premium cigar use patterns is essential for minimizing public health harms. Typically, premium cigars are handmade, larger, more expensive, and without the characterizing flavors that are present in other cigar types: Nonpremium traditional cigars, cigarillos, and filtered cigars.

Aims and Methods
Self-reported brand and price data were used from Wave 6 of the Population Assessment of Tobacco and Health (PATH) Study to define and estimate premium versus nonpremium cigar use among U.S. adults, as well as to explore cigar smoking patterns, purchasing behavior, and reasons for use by cigar type.

Results
In 2021, 0.9% (95% CI = 0.7–1.0) of adults were premium cigar users, compared to 0.4% of nonpremium traditional cigar users (95% CI = 0.3–0.5), 1.1% of cigarillo users (95% CI = 1.0–1.2), and 0.6% filtered cigar users (95% CI = 0.5–0.7). Premium cigar users were overwhelmingly male (97.7%), and 35.8% were aged ≥55 years. The average premium cigar price/stick was $8.67, $5.50–7.00 more than other cigar types. Compared to other cigar types, significantly fewer premium cigar users had a regular brand with a flavor other than tobacco (~15% vs. 38%–53%). Though flavors remained the top reason for premium cigar use, they were less likely to endorse flavors as a reason for use than other cigar users (~40% vs. 68–74%). Premium cigar users had a lower prevalence (aRR: 0.37, 95% CI = 0.25–0.55) of dual use of cigars and cigarettes.

Conclusions
Although &lt;1% of U.S. adults use premium cigars, their use and purchasing characteristics continue to differ from other cigar types, highlighting the importance of capturing data specific to premium cigar use.

Implications
This manuscript extends previous research from the National Academies of Science, Engineering, and Medicine report, “Premium cigars: Patterns of use, marketing, and health effects” by utilizing the most recent PATH Study data (Wave 6) to examine patterns of cigar use, including purchasing behavior and reasons for use, by cigar type (eg, premium traditional cigars, nonpremium traditional cigars, cigarillos, and filtered cigars). The findings support continued research on patterns of premium cigar use, which differ from use patterns of other cigar types.
Political Transactions, the Social Contract, and Administrative Power
Authors: Eckerd Adam 
Published: July 2023

Abstract
Although power has frequently been noted as a key to understanding administration, the concept of administrative power has remained ill-defined. In this essay I offer a definition of administrative power based on the social contract, arguing that administrative power is the transactional granting of power by the people in exchange for services and a reduction in uncertainty that agencies provide. I elaborate on the role of communication and persuasion in garnering administrative power and conclude by offering arguments, based on both risk communication and political spin, for how agencies acquire and maintain administrative power in the 21st Century.
A population-based study of caesarean section in women with juvenile idiopathic arthritis
Authors: Götestam Skorpen Carina , Lydersen Stian , Salvesen Kjell Å , Wallenius Marianne 
Published: July 2023

AbstractObjectivesThe literature on delivery methods in women with JIA is limited. Active inflammation is a risk factor for caesarean section (CS) in other arthritic diseases. A CS entails a higher risk for complications than vaginal delivery and restricted physical activity in the first weeks after birth. Our objective was to explore a possible association of inflammatory active disease and the proportion of CS in women with JIA.MethodsData from the Norwegian nationwide observational register RevNatus were linked with data from the Medical Birth Registry of Norway (MBRN). Cases comprised singleton births in women with JIA (n = 196) included in RevNatus from 2010 to 2019. Singleton births registered in the MBRN during the same period of time, excluding births in mothers with rheumatic inflammatory diseases, served as population controls (n = 575 798).ResultsCS was more frequent in women with JIA (20.4%) and in the subgroup of women with inflammatory active JIA (30.0%) than in population controls (15.6%). Women with active JIA had a risk for elective CS similar to population controls [risk difference 2.3% (95% CI −2.5, 12.9)] and a higher risk for emergency CS [risk difference 14.0% (95% CI 4.3, 27.4)] compared with population controls.ConclusionWomen with active JIA had a higher risk for emergency CS, but not elective CS, compared with population controls.
Who Mismanages Student Loans, and Why?
Authors: Cornaggia Kimberly , Xia Han 
Published: July 2023

Abstract
Many financially distressed students who qualify for federal assistance plans with interest moratorium and principal forgiveness instead accrue interest over long periods of nonpayment. This loan mismanagement is associated with higher delinquency. Mismanagement varies significantly across student gender and race: it is more prominent among male and non-white students. Mismanagement also varies across loan servicers, depending on proxies for student-adverse servicer policies. We consider explanations based on student selection and servicer treatment for loan mismanagement. Student financial literacy plays an important role but variation in treatment on the part of loan servicers appears more important.

Evaluation of saturated and unsaturated fat with vitamin A or beta-carotene supplementation in nursery pigs
Authors: Elefson Sarah , Greiner Laura 
Published: July 2023

Abstract
One hundred and fifty-two nursery pigs (PIC, Hendersonville, TN) were randomly assigned to mix sex pens and one of six dietary treatments in a 3 × 2 factorial. Diets included no added fat, 3% added choice white grease, or 3% added soy oil with either a supplemented vitamin A (for a total of 11,640 IU vitamin A/kg, Rovimix A 1000, DSM, Parsippany, NJ, US) or beta-carotene (for a total of 8,708 IU vitamin A/kg equivalent, Rovimix β-Carotene 10%, DSM). Pigs were given a 3-d adaptation period upon arrival. Pigs were weighed at the start of the study and at the end of each phase. A blood sample was taken from one pig per pen at the start and end of the study. Tissues were collected from eight pigs at the start of the study and six pigs per treatment at the end of the study. Data were analyzed via the GLIMMIX procedure in SAS 9.4 (SAS Inst., Cary, NC). Pen was the experimental unit, and repeated measures were used for growth performance and blood parameters. There was no fat by supplement interaction (P &gt; 0.05) on body weight (BW), but there was a tendency (P = 0.054) for heavier BWs when soy oil was added to diets. There was no difference (P &gt; 0.05) in average daily feed intake or average daily gain (ADG). There was an improved gain:feed (P = 0.02) when pigs were fed choice white grease over no added fat. There were time differences (P &lt; 0.05) for plasma vitamins A (retinol), D (25 hydroxy vitamin D3), and E (alpha-tocopherol). Vitamin A and D values were higher at the end of the study, whereas vitamin E values were lower at the end of the study. The choice white grease diets had the highest (P &lt; 0.05) plasma vitamins D and E (6.74 ng/mL and 2.87 ppm, respectively). Pigs supplemented with vitamin A had higher (P &lt; 0.05) hepatic vitamin A than pigs supplemented with beta-carotene (19.9 vs. 15.6 ppm, respectively). There were no differences (P &lt; 0.05) between immunoglobulins G and M or mRNA abundance of select genes (retinol binding protein 2, alcohol dehydrogenase class 1, lecithin retinol acyltransferase phosphatidylcholine-retinol O-acyltransferase, and beta-carotene oxygenase 1). In conclusion, fat inclusion level and type, with either vitamin A or beta-carotene supplementation, did not affect the overall nursery pig growth performance. The addition of fat resulted in an increase in ADG and BW. Diets with choice white grease had the highest plasma vitamins D and E, and supplemental vitamin A increased hepatic vitamin A.
