ABUNDANCES OF RED GIANTS IN OLD OPEN CLUSTERS. V. Be 31, Be 32, Be 39, M 67, NGC 188, AND NGC 1193

We present a detailed abundance analysis based on high resolution spectroscopy for 16 stars in the old open clusters Be 31, Be 32, Be 39, M 67, NGC 188, and NGC 1193. Average cluster metallicities of [Fe/H] = −0.30 ± 0.02, −0.21 ± 0.01, +0.03 ± 0.07, +0.12 ± 0.02, and −0.22 ± 0.14 (s.d.) have been found for Be 32, Be 39, M 67, NGC 188, and NGC 1193, respectively. The two stars observed in the field of Be 31 have disparate radial velocities and elemental abundance patterns, and also disagree with the possible Be 31 star studied by Yong et al. We conclude that membership has yet to be established for this important cluster, and therefore no element abundances measured here or in previous studies of Be 31 should be taken as definitive cluster abundances. A careful comparison of our results for the clusters M 67 and Be 32 to those of other studies shows general good agreement and identifies systematic differences resulting from different analyses. After combination of our results with those of other studies for clusters spanning the full Rgc range of the thin disk, we explore the abundance distributions as a function of Rgc and age for the elements Fe, O, Na, Mg, Al, Si, Ca, Ti, and Ni. As found in previous work, the [Fe/H] gradient appears to be continuous up to Rgc ∼ 13 kpc before flattening in the outer disk. [X/Fe] ratios show a scatter of 0.2–0.3 dex at all Rgc, for all elements considered. The [X/Fe] values of the six clusters analyzed here are consistent with those of other clusters of similar metallicity and Galactocentric location. Our whole cluster sample shows trends of increasing [O/Fe] and [Al/Fe] with age, although these trends vanish with the inclusion of other clusters from the literature. Larger, homogeneous open cluster samples are necessary to verify the existence and magnitude of abundance trends with age.
Priorities for alleviating menopausal symptoms after cancer

Menopausal symptoms from chemoradiation or adjuvant endocrine therapy for common cancers are distressing for women and may affect quality of life. This study reports severity and priorities for treatment among female cancer survivors seeking care for menopausal symptoms. Abstract Objective To determine treatment priorities in women cancer patients attending a dedicated Menopausal Symptoms After Cancer service. Methods Cancer type and stage were abstracted from medical records. Women ranked up to three symptoms as treatment priorities from the list “hot flushes/night sweats,” “mood changes,” “vaginal dryness or soreness,” “sleep disturbances,” “feeling tired or worn out (fatigue),” “sexual problems and/or pain with intercourse,” “joint pain,” and “something else” with free-text response. For each prioritized symptom, patients completed standardized patient-reported outcome measures to determine symptom severity and impact. Results Of 189 patients, most had breast cancer (48.7%, n = 92), followed by hematological (25.8%, n = 49), gynecological (18.0%, n = 34), or colorectal (2.6%, n = 5). The highest (first-ranked) treatment priority was vasomotor symptoms (33.9%, n = 64), followed by fatigue (18.0%, n = 34), vaginal dryness/soreness (9.5%, n = 18), and sexual problems/pain with intercourse (9.5%, n = 18). Symptoms most often selected in the top three (“prioritized”) were fatigue (57.7%, n = 109), vasomotor symptoms (57.1%, n = 108), and sleep disturbance (49.2%, n = 93). In patients who prioritized vasomotor symptoms, medians on the “problem,” “distress,” and “interference” dimensions of the Hot Flash Related Daily Interference Scale were, respectively, 6.0 (interquartile range [IQR], 5.0-8.0), 5.5 (IQR, 3.0-8.0), and 5.0 (IQR, 3.-7.0), indicating moderate severity. In patients who prioritized fatigue, the median Fatigue Scale score was 28 (IQR, 19-36), 37% worse than general population. Conclusions Vasomotor symptoms, fatigue, sexual problems, and vaginal dryness/soreness were the leading priorities for treatment. Understanding symptom severity and patient priorities will inform better care for this growing population.
Addition of Transversus Abdominis Plane Block to Conventional Pain Regimens in Robotic Sacrocolpopexy Procedures—A Pilot Randomized Controlled Trial (SACROTAP)

Importance There have been no randomized trials assessing the benefits of integration of transversus abdominis plane (TAP) blocks in sacrocolpopexy procedure postoperative pain management. Objective The aim of this study was to assess the variation in pain perception upon adding TAP blocks to conventional oral pain medications in patients undergoing sacrocolpopexy. The primary outcome was the reduction in pain reported using the numeric rating scale (NRS) among patient groups. The secondary outcome was the change in narcotic analgesic use postoperatively. Study Design This was a prospective double-blind, pilot randomized controlled trial of women undergoing robotic sacrocolpopexy, with and without supracervical hysterectomy, with 20 patients enrolled in each arm. Randomization included receiving a TAP block in addition to the conventional analgesic regimen. Results A total of 48 women were approached to participate in the study; 40 women provided consent (20 per study arm) and completed the 7-day follow-up. Patients receiving a TAP block had lower NRS pain scores at 4 hours postoperatively (4.95 ± 0.76 vs 5.50 ± 0.61, P = 0.02), 7 days postoperatively (2.20 ± 1.11 vs 3.15 ± 1.04, P = 0.008), and lower cumulative NRS pain scores at 48 hours postoperatively (14.90 ± 2.2 vs 16.60 ± 2.04, P = 0.02) and 7 days postoperatively (17.10 ± 2.63 vs 19.75 ± 2.65, P = 0.003) than patients not receiving a block. Patients in the intervention group also had lower cumulative morphine milliequivalents at 7 days postoperatively (17.25 ± 10.7 vs 29.25 ± 14.53, P = 0.005). Conclusion Use of TAP blocks in robotic sacrocolpopexy cases, with or without concurrent hysterectomy, may reduce postoperative pain and narcotic medication needs.
Practice patterns and perspectives regarding treatment for symptoms of menopause: qualitative interviews with US health care providers

US healthcare providers reported prescribing therapies for menopausal symptoms and noted that these therapies were perceived as generally effective; however, barriers to initiation of prescription therapy exist and new treatment options are needed. Abstract Objective To document health care providers' views regarding treatments for symptoms associated with menopause and discussions with patients about symptoms and treatment decisions. Results informed development of a data collection form for a retrospective medical record review (reported separately). Methods Registered US gynecologists or primary care providers from all US regions were identified from local association directories and an in-house database and were invited to participate in a qualitative interview if they consulted with three or more patients per week presenting with menopausal symptoms. Participants provided demographic data, information about patients' symptoms, and health care provider and patient views on prescription and nonprescription therapies. Key concepts/themes from interviews were identified. Results Participating health care providers (10 gynecologists, 10 primary care providers) agreed there are effective treatment options for menopausal symptoms, particularly vasomotor symptoms and vaginal dryness and/or atrophy. Health care providers reported that treatment was generally dictated by symptoms that interfered with quality of life and/or daily activities, although patients often had symptoms for months before presentation. All health care providers said they prescribe hormone and/or nonhormone therapies for treatment of menopausal symptoms; half stated that they typically inquire about patients' nonprescription therapy use, and 45% recommend specific nonprescription therapies. The most commonly cited barriers to initiation of any therapy for menopausal symptoms were patient concerns about risks and financial considerations (ie, insurance or cost). Conclusions US health care providers reported prescribing therapies for menopausal symptoms and noted that these therapies were perceived as generally effective; however, barriers to initiation of prescription therapy exist, and new treatment options are needed.
Urinary Tract Infections Among Gender Diverse People Assigned Female at Birth on Testosterone

Importance The current literature lacks evidence to support the relationship between gender-affirming testosterone use and urinary tract infections (UTIs). Objectives The aims of the study are to compare UTI rates among gender diverse people assigned female at birth on testosterone (GDT) to cisgender women (CW) and to identify factors associated with UTI. Study Design This is a retrospective cohort study of GDT and age-matched CW over a 5-year period. The primary outcome was based on the International Classification of Diseases, Ninth/Tenth Revisions, Clinical Modification, UTI diagnosis codes with a filled pharmacy order for antibiotics within 7 days of the diagnosis. Results The study included 2,401 GDT who were then age matched to 2,401 CW. The mean rates of UTI among GDT and CW were not significantly different at 0.09 and 0.10 UTIs per year, respectively. During the study period, 6.9% of GDT and 7.5% of CW had at least 1 UTI. Diabetes mellitus type 1 or 2 was significantly associated with UTI frequency among CW (P = 0.04) but not GDT (P = 0.96). Conclusions The rate of UTIs among our young cohort of GDT and CW was similarly low. Diabetes mellitus type 1 or 2 was significantly associated with UTIs among CW but not GDT. These findings suggest that testosterone-induced vaginal atrophy may not be associated with a higher a UTI risk. A deeper understanding of the pathogenesis of UTI in people assigned female at birth and more data on the relationship between testosterone and UTIs are needed before recommending vaginal estrogen to all GDT with recurrent UTI.
Superficial dyspareunia treatment with hyperstacking of erbium:yttrium-aluminum-garnet SMOOTH laser: a short-term, pilot study in breast cancer survivors

Hyperstack treatment of the introitus and vestibulum can increase the effect of vaginal erbium laser on superficial dyspareunia in postmenopausal breast cancer survivors. This effect is independent from age and years since menopause, suggesting that it could be of help for all postmenopausal women. Abstract Objective This prospective pilot study aimed to evaluate the effects of a modified vaginal erbium laser (VEL) protocol, using the hyperstack mode on the vaginal vestibulum and introitus to treat superficial dyspareunia in postmenopausal breast cancer survivors suffering from the genitourinary syndrome of menopause. Methods In this pilot, prospective, randomized study, two groups of postmenopausal women suffering from superficial dyspareunia were included: 34 women (VEL group) were treated with erbium laser crystal yttrium-aluminum-garnet (XS Fotona SMOOTH; Fotona, Ljubljana, Slovenia) with a wavelength of 2,940 nm; for the other 34 (hyperstack group), a modified second step of the VEL protocol for the treatment of vestibulum and introitus was used, with hyperstacked (repeating a number of) subablative, long pulses with very low fluences. For each group, three laser applications at 30-day intervals were performed. Symptoms were assessed before, after each application, and after 1 and 3 months from the last laser application, using the visual analog scale score for superficial dyspareunia. Results Superficial dyspareunia improved in both groups over time (P < 0.001), regardless of age and years since menopause status. The reduction in visual analog scale score after the third laser application was 58% in VEL versus 73.5% in hyperstack. The hyperstack group, since the first laser application, showed a greater (P < 0.001) and persistent improvement of superficial dyspareunia. Conclusions The hyperstack treatment of the introitus and vestibulum in breast cancer survivors leads to a more significant improvement in superficial dyspareunia than the VEL alone.
The impact of systemic racism on health outcomes among Black women

Numerical study of boundary layer separation control using magnetogasdynamic plasma actuators

In this study, an efficient, time dependent, two-dimensional Navier–Stokes numerical code for shockwave boundary layer interaction in air is developed. Nonthermal surface plasma actuation is evaluated for effective shockwave induced boundary layer separation control within supersonic inlets. Specifically, high speed magnetogasdynamic plasma actuators are of interest. In these, localized ionization is produced close to the wall surface and then the flow is accelerated using strong magnetic fields. To replicate the experiments done at large boundary layer thickness, the code is divided into time independent and time dependent regimes to significantly reduce computation time. Computational results are in good agreement with experiments in terms of the flow structure as shown by Schlieren imaging, acetone planar laser scattering, and the static pressure profile on the test section wall.
On Diffusive Climatological Models

Abstract A simple, zonally and annually averaged, energy-balance climatological model with diffusive heat transport and nonlinear albedo feedback is solved numerically. Some parameters of the model are varied, one by one, to find the resultant effects on the steady solution representing the climate. In particular, the outward radiation flux, the insulation distribution and the albedo parameterization are varied. We have found an accurate yet simple analytic expression for the mean annual insolation as a function of latitude and the obliquity of the Earth's rotation axis; this has enabled us to consider the effects of the oscillation of the obliquity. We have used a continuous albedo function which fits the observed values; it considerably reduces the sensitivity of the model. Climatic cycles, calculated by solving the time-dependent equation when parameters change slowly and periodically, are compared qualitatively with paleoclimatic records.
Forming Coalition Sets from Directional Radios

Fifth Generation (5G) mobile networks aim to exploit the vast amount of spectrum in the millimeter wave (mmWave) and Terahertz bands for more capacity. mmWave/Terahertz radios fundamentally differ from existing wireless systems in terms of directivity, propagation loss, and blockage sensitivity. As these mmWave/Terahertz directional antennas/nodes are becoming part of mainstream wireless networks, effective and efficient forming of coalitions from such nodes is of interest for the goal of increasing the sum rate of a wireless network. We design a novel heuristic framework to form sets of coalitions by categorizing directional radio nodes and distributing them into coalitions while assuring that no node is isolated, and show that polynomial-time heuristics can perform well in forming coalition sets out of directional radios.
Public Awareness of Obesity and Risk of Pelvic Floor Disorders: A Cohort Study

Importance Obesity is a risk factor for pelvic floor disorders (PFDs), but limited information exists about the public awareness of this association. Objective Our primary objective was to assess awareness of the association between obesity and PFDs, comparing 2 cohorts of women with body mass index (BMI) <30 versus BMI ≥30. Study Design We conducted a cross-sectional, survey-based cohort study. The survey included questions about demographics, height and weight self-assessment, and the risk of PFDs with obesity. Our primary outcome was the rate of women correctly identifying that obesity increases the risk of PFDs. Results Of 377 eligible participants 272 (72.1%) completed the survey, with 266 analyzed. Of these, 159 (59.8%) had a BMI <30 and 107 (40.2%) had a BMI ≥30. Comparing the cohorts, the lower BMI cohort was older (mean age of 54.4 ± 18.3 vs 48.4 ± 17.5 years, P = 0.008) and had higher rates of graduate/professional school (35.2% vs 19.6%, P = 0.04). Both groups had similarly high rates of PFDs. There was no difference in identifying obesity as a risk factor for PFDs, although the lower BMI group was less likely to identify the implications of weight loss on urinary incontinence (UI) (27.7% vs 45.8%, P = 0.002). Controlling for potential confounders, obesity remained positively associated with knowledge about the implications of weight loss on UI (odds ratio, 2.5; 95% confidence interval, 1.5–4.4). Conclusions Few women identified the increased risk of PFDs with obesity. Obese women may have increased awareness of the implications of weight loss on UI.
Evolutionary realism: a new ontology for economics

The renaissance in evolutionary economics in the past two decades has brought with it a great deal of theoretical development and interdisciplinary import. Much of this has been useful, but not all of it has been commensurate. In this paper, we make the case for the limits to theoretical developments that lack clearly specified ontological commitments by attempting an inductive synthesis of the ontological content of empirical generalizations in evolutionary economics. We call this ‘evolutionary realism’ and present it in three axioms – (1) all existences are bimodal matter‐energy actualizations of ideas, (2) all existences associate, and (3) all existences are processes. We conclude with discussion of the sort of analytical framework that we might consistently build on these axioms; a three‐level analytical structure of micro, meso and macro domains.
Persistent and Pernicious Errors in Algebraic Problem Solving

Students hold many misconceptions as they transition from arithmetic to algebraic thinking, and these misconceptions can hinder their performance and learning in the subject. To identify the errors in Algebra I which are most persistent and pernicious in terms of predicting student difficulty on standardized test items, the present study assessed algebraic misconceptions using an in-depth error analysis on algebra students’ problem solving efforts at different points in the school year. Results indicate that different types of errors become more prominent with different content at different points in the year, and that there are certain types of errors that, when made during different levels of content are indicative of math achievement difficulties. Recommendations for the necessity and timing of intervention on particular errors are discussed.
Scaling of domain periodicity with thickness measured in BaTiO3 single crystal lamellae and comparison with other ferroics

The focused ion beam microscope has been used to cut parallel-sided {l_brace}100{r_brace}-oriented thin lamellae of single crystal barium titanate with controlled thicknesses, ranging from 530 nm to 70 nm. Scanning transmission electron microscopy has been used to examine domain configurations. In all cases, stripe domains were observed with {l_brace}011{r_brace}-type domain walls in perovskite unit-cell axes, suggesting 90 deg. domains with polarization in the plane of the lamellae. The domain widths were found to vary as the square root of the lamellar thickness, consistent with Kittel's law, and its later development by Mitsui and Furuichi and by Roytburd. An investigation into the manner in which domain period adapts to thickness gradient was undertaken on both wedge-shaped lamellae and lamellae with discrete terraces. It was found that when the thickness gradient was perpendicular to the domain walls, a continuous change in domain periodicity occurred, but if the thickness gradient was parallel to the domain walls, periodicity changes were accommodated through discrete domain bifurcation. Data were then compared with other work in literature, on both ferroelectric and ferromagnetic systems, from which conclusions on the widespread applicability of Kittel's law in ferroics were made.
Epitaxial growth of ferromagnetic Ni2MnGa on GaAs(001) using NiGa interlayers

Heusler alloy Ni2MnGa thin films have been grown pseudomorphically on a relaxed NiGa interlayer on GaAs(001) by molecular-beam epitaxy. In situ reflection high-energy electron diffraction patterns, ex situ x-ray diffraction, and cross-sectional view transmission electron microscopy electron diffraction patterns confirm the single-crystal growth of Ni2MnGa. The films grow pseudomorphically on the relaxed NiGa interlayer with a tetragonal structure (a=b=5.79 A and c=6.07 A). Magnetic measurements using vibrating sample and superconducting quantum interference device magnetometers reveal Ni2MnGa to have an in-plane easy axis and a Curie temperature ∼350 K.
TURBULENT BOUNDARY-LAYER CONTROL BY MEANS OF SPANWISE-WALL OSCILLATION

An experimental investigation into the changes in turbulence structure of the boundary layer over a wall oscillating in spanwise direction was carried out in a wind tunnel using hot-wire anemometry and flow visualisation. The main purpose of this investigation is to confirm recent numerical results which seem to indicate that the turbulent skinfriction drag can be reduced by up to 40 percent over the oscillating wall. The results from the present investigation clearly indicate that the logarithmic velocity profiles are shifted upwards and turbulence intensities reduced by the spanwise-wall oscillation, confirming the basic conclusions of recent direct numerical simulation. Also, the skinfriction reductions as much as 45% are observed in the present experiment at an optimum speed of wall oscillation. The flow-visualisation study indicates that the longitudinal vortices in the near-wall region of the boundary layer are twisted towards the direction of spanwise-wall motion with oscillation. As a result, the vortices are realigned into the cross-flow direction, resulting in a reduction of turbulent wall-skin friction by spanwise-wall oscillation. A conceptual model for a turbulent boundary layer over an oscillating wall is proposed to examine the mechanism of turbulent drag reduction by spanwise-wall oscillation.
