The massive star population in the giant H ii region Tol 89 in NGC 5398

We present new high spectral resolution Very Large Telescope (VLT)/UV-Visual Echelle Spectrograph (UVES) spectroscopy and archival Hubble Space Telescope (HST)/Space Telescope Imaging Spectrograph (STIS) imaging and spectroscopy of the giant H II region Tol 89 in NGC 5398. From optical and ultraviolet (UV) HST images, we find that the star-forming complex as a whole contains at least seven young compact massive clusters. We resolve the two brightest optical knots, A and B, into five individual young massive clusters along our slit, A1-4 and Bl, respectively. From UV spectral modelling using the STARBURST99 code of Leitherer et al., and nebular Hβ equivalent widths in the optical, we derive ages that are consistent with the formation of two separate burst events, of ∼4 ± 1 Myr and <3 Myr for knots A (A1-4) and B (B1), respectively. A Large Magellanic Cloud (LMC) metallicity is measured for both knots from a nebular line analysis, while nebular He II 4686 is observed in knot B and perhaps in knot A. We detect underlying broad wings on the strongest nebular emission lines indicating velocities up to 600 km s -1 . From UV and optical spectroscopy, we estimate that there are ∼95 early WN stars and ∼35 early WC stars in Tol 89-A, using empirical template spectra of LMC Wolf-Rayet (WR) stars from Crowther & Hadfield, with the WC population confined to cluster A2. Remarkably, we also detect a small number of approximately three mid WNs in the smallest (mass) cluster in Tol 89-A, A4, whose spectral energy output in the UV is entirely dominated by the WN stars. From the strength of nebular Hβ, we obtain N(O) ∼ 690 and 2800 for knots A and B, respectively, which implies N(WR)/N(O) ∼ 0.2 for knot A. We also employ a complementary approach using STARBURST99 models, in which the O star content is inferred from the stellar continuum, and the WR population is obtained from spectral synthesis of optical WR features using the grids from Smith et al. We find reasonable agreement between the two methods for the O star content and the N(WR)/N(O) ratio but find that the WR subtype distribution is in error in the STARBURST99 models, with far too few WN stars being predicted. We attribute this failure to the neglect of rotational mixing in evolutionary models. Our various modelling approaches allow us to measure the cluster masses. We identify Al as a super star cluster (SSC) candidate with a mass of ∼1-2 x 10 5 M ⊙ . A total mass of ∼6 x 10 5 M ⊙ is inferred for the ionizing sources within Tol 89-B.
A General Systems Theory for Rain Formation in Warm Clouds

A cumulus cloud model which can explain the observed characteristics of warm rain formation in monsoon clouds is presented. The model is based on classical statistical physical concepts and satisfies the principle of maximum entropy production. Atmospheric flows exhibit selfsimilar fractal fluctuations that are ubiquitous to all dynamical systems in nature, such as physical, chemical, social, etc and are characterized by inverse power law form for power (eddy energy) spectrum signifying long-range space-time correlations. A general systems theory model for atmospheric flows developed by the author is based on the concept that the large eddy energy is the integrated mean of enclosed turbulent (small scale) eddies. This model gives scale-free universal governing equations for cloud growth processes. The model predicted cloud parameters are in agreement with reported observations, in particular, the cloud dropsize distribution. Rain formation can occur in warm clouds within 30minutes lifetime under favourable conditions of moisture supply in the environment.
A Novel Framework for Road Side Unit Location Optimization for Origin-Destination Demand Estimation

This study deals with the problem of road side unit (RSU) location optimization for origin-destination (OD) demand estimation. With the point-to-point measurement provided by RSUs in connected vehicle environment, the errors of OD demand estimation come from two sources: 1) the lack of enough path flow information; and 2) the vehicle-to-RSU (V2R) communication delay. However, increasing the amount of path flow information collected by RSUs results in the increase of V2R communication delay encountered by each collected data packet. Moreover, it is difficult to find a global optimal solution by formulating the problem as a single objective program. To address the investigated problem, this study proposes a novel framework consisting of solving a bi-objective RSU location optimization problem and an OD demand estimation problem. This RSU location optimization problem is formulated as a bi-objective nonlinear binary integer program to balance the maximization of the amount of path flow information and the minimization of V2R communication delay. The OD demand estimation problem is formulated as a least square estimator to identify the RSU location scheme with the smallest OD demand estimation error, among the Pareto optimal solutions to the bi-objective program. An efficient $\varepsilon $ -constraint method is developed to generate the Pareto optimal solutions. The numerical example demonstrates that the proposed framework achieves 6.95 lower root-mean-square error of OD demand estimation, compared with the baseline framework.
Factors Affecting Mothers’ Adherence to Home Exercise Programs Designed for Their Children with Cerebral Palsy

Cerebral palsy is a common motor disorder that results in long-term impairment. The purpose of this study was to find out what factors influence Saudi mothers’ compliance with their Children with Cerebral Palsy (C-CP) Home Exercise Program (HEP). A self-administered online questionnaire was used to perform this qualitative research study on a group of 113 mothers who had children with CP. The study included mothers with children from birth to 12 years old who had received a HEP prescription from a physiotherapist. The measuring instrument tool was a questionnaire with two sections: demographic characteristics and a questionnaire about the parents’ adherence to the HEP. The questionnaire utilized in this study was subjected to a reliability analysis, and the derived Cronbach’s alpha was found to be 0.814 for the questionnaire (which had 17 phrases). These results imply that the questionnaire is reliable. A total of 113 responses were received, with 4 incomplete responses being eliminated. The majority of mothers (66.1%) did not follow the HEP, according to the findings of this survey. The demographics of the mothers revealed that 20–25-year-old mothers were more adherent than the other age groups. The findings of this study demonstrated that the physical therapist’s treatment of the mother influenced exercise compliance.
Effect of Soil Amendments Derived from Agricultural Biomass on Rice Yield and Soil Fertility in a Paddy Field of South Korea

: The objective of this study was to compare the effects of biochar and straw applications on rice yield and soil fertility during a three-year period. The three treatment conditions were: BC (barley straw biochar 2000 kg ha −1 ), BS (barley straw 2000 kg ha −1 ), and BC + BS (barley straw biochar 1000 kg ha −1 + barley straw 1000 kg ha −1 , respectively). Each treatment area was separated by an untreated control (CN) area. During the study, rice yields for CN, BC, BS, and BC + BS treatments ranged on average from 473 to 515, 497 to 532, 516 to 528, and 583 to 602 g m −2 , respectively. Among the treatments, the BC + BS treatment produced the highest average rice yield and the BC + BS rice yield was stable during the three-year study. The soil changes after the final rice harvesting were different in the BC and BS application areas. Soil bulk density and pH were improved in all treatments except the CN treatment when compared to those of raw soil. The SOC and TN content after BC application increased by 0.56 and 0.08 g kg −1 , respectively, compared to those of the CN soil, while those after BS and BC + BS application increased by 0.89–1.36 and 0.16–0.3 g kg −1 , respectively. The soil CEC values after BC, BS, and BC + BS treatment were 0.55, 0.37, and 0.49 cmol c kg −1 higher than those in the CN, respectively. Therefore, such an approach can reduce the application of inorganic fertilizer, thereby encouraging the development of sustainable organic agriculture.
Iranian EFL Students’ L2 Engagement: The Impact of Teacher Support and Teacher-student Rapport

Given that L2 engagement serves a vital role in students’ academic success, studying the predictors of this construct seems critical. Notwithstanding, factors influencing one’s engagement in an L2 context have remained unclear. To respond to this gap, the current research aimed to unravel the effects of teacher-student rapport and teacher support on Iranian EFL students’ L2 engagement. In doing so, 216 Iranian students majoring in Applied Linguistics, Linguistics, English Translation, or English Literature were invited to cooperate in this investigation. To obtain the required data, three pre-designed scales were virtually distributed among the respondents. Then, through correlation tests, the association between teacher support, teacher-student rapport, and student L2 engagement was measured. Following that, the effects of teacher-student rapport and teacher support on Iranian students’ L2 engagement was assessed using Structural Equation Modeling (SEM). The correlational analysis uncovered a strong, favorable association between constructs. The SEM analysis also indicated that teacher-student rapport and teacher support can strongly influence Iranian students’ engagement in EFL classes. The implications of results are further discussed.
Expected Returns to Crime and Crime Location

IZA DP No. 15520 AUGUST 2022 Expected Returns to Crime and Crime Location* We provide first evidence that temporal variations in the expected returns to crime affect the location of property crime. Our identification strategy relies on the widelyheld perception in the UK that households of South Asian descent store gold jewellery at home. Price movements on the international market for gold exogenously affect the expected gains from burgling these households, which become relatively more lucrative targets as the gold price increases. Using a neighbourhood-level panel on reported crime and difference-in-differences, we find that burglaries in South Asian neighbourhoods are more sensitive to variations in the gold price than other neighbourhoods in the same municipality, confirming that burglars react rationally to variations in the expected returns to their activities. We conduct a battery of tests on neighbourhood and individual data to eliminate alternative explanations. JEL Classification: K42, J19

3D-Printed PCL Scaffolds Combined with Juglone for Skin Tissue Engineering

Skin diseases are commonly treated with antihistamines, antibiotics, laser therapy, topical medications, local vitamins, or steroids. Since conventional treatments for wound healing (skin allografts, amnion, xenografts, etc.) have disadvantages such as antigenicity of the donor tissue, risk of infection, or lack of basement membrane, skin tissue engineering has become a popular new approach. The current study presents the design and fabrication of a new wound-dressing material by the addition of Juglone (5-hydroxy-1,4-naphthoquinone) to a 25% Polycaprolactone (PCL) scaffold. Juglone (J) is a significant allelochemical found in walnut trees and, in this study is used as a bioactive material. The effects of different amounts of J (1.25, 2.5, 5, 7.5, and 10 mg) on the biocompatibility, mechanical, chemical, thermal, morphological, and antimicrobial properties of the 3D-printed 25% PCL scaffolds were investigated. The addition of J increased the pore diameter of the 25% PCL scaffold. The maximum pore size (290.72 ± 14 µm) was observed for the highest amount of J (10 mg). The biocompatibility tests on the scaffolds demonstrated biocompatible behavior from the first day of incubation, the 25% PCL/7.5 J scaffold having the highest viability value (118%) among all of the J-loaded scaffolds. Drug release of J into phosphate buffered saline (PBS) at pH 7.4 showed that J was completely released from all 25% PCL/J scaffolds within 7 days of incubation.
Hub-Based Community Finding

This article presents a hub-based approach to community finding in complex networks. After identifying the network nodes with highest degree (the so-called hubs), the network is flooded with wavefronts of labels emanating from the hubs, accounting for the identification of the involved communities. The simplicity and potential of this method, which is presented for direct/undirected and weighted/unweighted networks, is illustrated with respect to the Zachary karate club data, image segmentation, and concept association. Attention is also given to the identification of the boundaries between communities.
Characterization of Romanian Bee Pollen—An Important Nutritional Source

Bee pollen represents an important bee product, which is produced by mixing flower pollens with nectar honey and bee’s salivary substances. It represents an important source of phenolic compounds which can have great importance for importance for prophylaxis of diseases, particularly to prevent cardiovascular and neurodegenerative disorders, those having direct correlation with oxidative damage. The aim of this study was to characterize 24 bee pollen samples in terms of physicochemical parameters, organic acids, total phenolic content, total flavonoid content, individual phenolics compounds, fatty acids, and amino acids from the Nort East region of Romania, which have not been studied until now. The bee pollen can be considered as a high protein source (the mean concentration was 22.31% d.m.) with a high energy value (390.66 kcal/100 g). The total phenolic content ranged between 4.64 and 17.93 mg GAE/g, while the total flavonoid content ranged between 4.90 and 20.45 mg QE/g. The high protein content was observed in Robinia pseudoacacia, the high content of lipids was observed in Robinia pseudoacacia pollen, the high fructose content in Prunus spp. pollen while the high F/G ratio was observed in Pinaceae spp. pollen. The high TPC was observed in Prunus spp. pollen, the high TFC was observed in Robinia pseudoacacia pollen, the high free amino acid content was observed in Pinaceae spp. pollen, and the high content of PUFA was reported in Taraxacum spp. pollen. A total of 16 amino acids (eight essential and eight non-essential amino acids) were quantified in the bee pollen samples analyzed. The total content of the amino acids determined for the bee pollen samples varied between 11.31 µg/mg and 45.99 µg/mg. Our results can indicate that the bee pollen is a rich source of protein, fatty acids, amino acids and bioactive compounds.
Articulating system change to effectively and justly address the climate crisis

ABSTRACT Activists and world leaders increasingly call for bold climate action. Yet proposals remain far from the transformative systemic changes required. While many remain in denial that system change is necessary, others who call for system change fail to articulate what that change would entail. It is critical that the climate movement identifies and promotes specific strategies for change. Identifying synergistic proposals associated with ecosocialism and degrowth, we describe a set of policies, programs, and strategies that have the potential to justly minimize warming and that could become key demands of climate movement organizations attempting to influence governments in the Global North. While there are stigmas associated with ecosocialism and degrowth, the described strategies can be promoted without using these terms. Articulating specific strategies for system change is necessary to challenge the powerful actors and interests that continue to maintain the status quo and our current climate trajectory.
Ultra-wideband and high frequency resonators using shear horizontal type plate wave in LiNbO3 thin plate

A cognitive radio system requires a tunable filter with a wide tunable range to compose a simple front-end. Because the tunable range is limited by the bandwidth (BW) of resonators, an ultra-wideband resonator is an important device to implement the tunable filter. The authors previously obtained low frequency resonators with a wide BWs of 26 to 29% and a large impedance ratios of 92 to 98 dB between resonance (fr) and anti-resonance frequencies (fa) using 0-th mode shear horizontal (SH0 mode) plate wave in a LiNbO3 plate. Also, a tunable filter with the tunable range of 13% was demonstrated. However, the frequency (fr =1.8 MHz and fa = 2.3 MHz) is too low for modern wireless communication. Also, the resonators suffered from ripples due to transverse mode between fr and fa. In this study, high frequency SH0 mode plate wave resonators (fr = 430–560 MHz and fa = 530–670 MHz) with a wide bandwidth and a large impedance ratio have been fabricated using an ultrathin LiNbO3 plate. The ripples were suppressed by an apodized interdigital transducer.
The Role of Child’s Age, Sex, and Temperament in Father Involvement during the Pre-School Years

(1) Background: The aim of the study was to explore how child’s characteristics (age, sex, and temperament) were associated with father’s involvement in child-related activities. In a sample of 410 bi-parental families with pre-school age children. (2) Methods: Dividing the sample into two age groups, OLS regression models were conducted for each dimension of father involvement with child characteristics as predicting variables. (3) Results: for the younger children (3 and 4 years) fathers were more involved in teaching/discipline and played with their more extroverted daughters. With older children (5 and 6 years), fathers were more involved in teaching/discipline and played when children were higher on negative-affectivity. An interaction was found with boys’ higher negative-affectivity, predicting fathers’ higher involvement in teaching and discipline. (4) Conclusions: Our results suggest that children’s characteristics have an impact on what fathers do, particularly in a dimension salient to pre-school years such as teaching/discipline. This can help build tailored empirical-sustained programs aiming to encourage and support fathers’ positive involvement.
Beneficial Contribution to Glucose Homeostasis by an Agro-Food Waste Product Rich in Abscisic Acid: Results from a Randomized Controlled Trial

The control of glucose homeostasis represents the primary goal for the prevention and management of diabetes and prediabetes. In recent decades, the hypoglycemic hormone abscisic acid (ABA) has attracted considerable interest in the scientific literature. In this regard, the high ABA concentration in immature fruits led us to consider these food matrices as candidates for diabetes control. Therefore, the beneficial efficacy of a nutraceutical formulation based on thinned nectarines (TNs) rich in ABA was tested through a three-month, three-arm, parallel-group, randomized controlled trial (RCT) conducted on sixty-one patients with type 2 diabetes (T2D). After 3 months, both the treatments with low doses of TN (500 mg 3 times/day) and high doses of TN (750 mg 3 times/day) showed a significant reduction in glycemic parameters compared to baseline. Treatment with low doses of TN showed a greater insulin-sparing effect (fasting plasma insulin, FPI: −29.2%, p < 0.05 vs. baseline) compared to the high-dose group (FPI: −16.5%, p < 0.05 vs. baseline). Moreover, a significant correlation between glycemia and ABA plasmatic levels was observed for both intervention groups at baseline and after 3 months. Overall, our data reasonably support TN as a promising and innovative nutraceutical product able to contribute to the management of glucose homeostasis.
Age does matter in adolescents and young adults vs. older adults with lung adenocarcinoma: A retrospective analysis comparing clinical characteristics and outcomes in response to systematic treatments

Adenocarcinoma is the most common histological type of lung cancer in adolescents and young adults (AYAs; ˂50 years of age). However, few clinical trials that have investigated systematic treatments regard AYAs as a special cohort, and the differences in progression-free survival (PFS) and overall survival (OS) between AYAs and older adults is still unclear. The present study compared clinical characteristics, targetable genomic mutations, toxicity, efficacy and prognostic response to systematic treatments in AYAs (n=251) and older adults (n=1,098) who were diagnosed with lung adenocarcinoma between January 2013 and December 2017 at YueBei People's Hospital (Shaoguan, China). Compared with older adults, AYAs with lung adenocarcinoma were more frequently female and non-smokers, with a higher ratio of patients receiving chemotherapy and targeted therapy, and fewer untreated. More AYAs harbored targetable genomic mutations, including epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) mutations, while more older adults harbored KRAS proto-oncogene GTPase mutations. EGFR L858R was significantly more prevalent among older adults, while 19Del was common in AYAs. AYAs showed a higher objective response rate (ORR) and a lower grade 3–4 treatment-related adverse event (TRAE) percentage following systematic chemotherapy, but shared a similar ORR and grade 3–4 TRAE percentage with older adults following targeted therapies. AYAs experienced a shorter progression-free survival time following EGFR-tyrosine kinase inhibitor (TKI) treatment due to the higher number of metastatic organs at the time of the initial cancer diagnosis. However, there was a survival advantage of AYAs over older adults in terms of the response to systemic chemotherapy, and an age of ˂50 years was indicated as one of the positive predictors for OS time. Overall, AYAs with lung adenocarcinoma harbored distinctive clinical and genomic characteristics, and exhibited PFS and OS disadvantages following first-line EGFR-TKIs and advantages following systematic chemotherapy. However, the age-related difference in prognosis existed solely in patients who received systematic chemotherapy.
