Investigating factors affecting rural crash frequency at marginal areas around cities in Iran: a random parameter modeling approach

ABSTRACT A significant portion of rural crashes in Iran occur in the marginal areas around cities. Exclusive crash frequency models should be developed to identify the factors affecting the occurrence of crashes in these areas. In this study, the rural crash data of highways leading to the city of Isfahan were employed to develop a negative binomial (NB) model as a constant-parameter model, along with random effects negative binomial (RENB) and random parameters negative binomial (RPNB) models as the models based on the random parameter approach. The modeling results indicated the superiority of the RPNB model over the two other models. According to the findings of this study, the traffic volume of roads and the proportion of local and non-local vehicles, the proportion of longitudinal distance-limit violation, the way of controlling access points, and the access to rest areas affected the crash frequency in the marginal areas around cities.
Associations between Maternal Education and Child Nutrition and Oral Health in an Indigenous Population in Ecuador

The global nutrition transition has increased the prevalence of childhood dental caries. Greater understanding is needed of the impact of social determinants—including maternal education—on child oral health. This is a cross-sectional analysis of a convenience sample of families of 458 indigenous Ecuadorian children aged 6 months through 6 years from 2011–2013. Data was collected by mother interviews and child dental and anthropometric examinations. Multivariate logistic and Zero-Inflated-Poisson regression analyses assessed associations between years of maternal education and maternal-child oral health practices and child oral health outcomes. Each additional year of maternal education was significantly (p < 0.05) associated with some healthier practices including greater likelihood of mothers and children drinking milk daily (OR 1.20; 95% CI 1.08, 1.34); and less healthy practices including greater likelihood of bottle-feeding children with sugary liquids (OR 1.14; 95% CI 1.06, 1.22) and to older age, giving children sweets daily, calming children with a bottle or sweets, and less likelihood of helping brush their children’s teeth (OR 0.93; 95% CI 0.88, 0.98). Each year of maternal education had a small but statistically non-significant influence on increasing the odds of children being among those who are cavity-free (OR 1.03; 95% CI 0.92, 1.16). Interventions to improve health outcomes should focus not just on maternal education but also address social and commercial determinants of health through nutrition and oral health education, as well as policies to reduce sugar and ensure universal access to oral health care.
Feedback boundary control of 2-D hyperbolic systems with relaxation

This paper is concerned with boundary stabilization of two-dimensional hyperbolic systems of partial differential equations. By adapting the Lyapunov function previously proposed by the second author for linearized hyperbolic systems with relaxation structure, we derive certain control laws so that the corresponding solutions decay exponentially in time. The result is illustrated with an application to water flows in open channels.
Cepstral analysis of ‘‘cold‐speech’’ for speaker recognition: A second look

Speech affected by colds continues to be an issue in speaker recognition technology. This study is a continuation of the ‘‘cold‐affected’’ speech project [R. G. Tull and J. C. Rutledge, J. Acoust. Soc. Am. 99, 2549(A) (1996)] which compared ‘‘cold‐speech’’ and normal/healthy speech of a male subject to analyze differences in vowel durations and mel‐cepstral coefficients. This new study analyzes the speech of two additional male subjects during a cold and after a cold to test speaker intrasession (‘‘cold‐speech’’ within the same recording session, normal speech within the same session), and speaker intersession (‘‘cold‐speech’’ versus normal speech on different days). The sentence being used for recording is the recitation of numbers: ‘‘1 2 3 4 5 6 7 8 9 10. ’’ The lower‐order mel‐cepstral coefficients are chosen as parameters (independent variable) in this study. The research for this study shows that there are patterns in the coefficients (c2 and c3) of ‘‘cold‐speech’’ that are different from the patterns.
Self-education Program for Osteoarthritis Reduces Sodium Intake, Knee Joint pain, and Serum Interleukin-17A level in Osteoarthritis Patients

Objectives: As it has been known that sodium may aggravate joint inflammation throuh IL-17A pathway and it can cause joint pain, the purpose of this study was to determine the effect of the Self Education Programs for Osteoarthritis (SEPO) intervention on sodium intake, knee join pain and IL-17A level in patients with knee osteoarthritis. Methods: This multicenter study was conducted in orthopedic and internal medicine outpatient wards in three hospitals. This research has received ethical approval. Patients were recruited based on accidental sampling, who met the inclusion criteria. SEPO intervention was carried out for 30 days, followed by provision of leaflets, posters, and handbook about osteoarthritis, daily WhatsApp education chat and/or video. Patients’ demographic, knee joint pain, and sodium intake data was collected during interview, using the Semi Quantitative Food Frequency Questionnaire (SQ_FFQ), and WOMAC (Western Ontario McMaster Osteoarthritis Index) whereas serum IL-17A was determined by using ELISA. The effect of SEPO was analyzed statistically using Mann Whitney tests (p< 0.05). Results: Total subjects recruited were 80, namely 30 patients in control group and 50 patients in treatment group. Majority of patients were female (74, 92.5%), age 56-65 yo (32, 40%), obese (54, 67.5%) and senior high school (23, 46%). Statistical results showed that following SEPO intervention daily sodium intake was lower (1289.45±457.98 mg) compared to the control group (2143.94±744.75 mg), p= 0.04. WOMAC score of control group (28±12.41) higher than treatment group (23.88±13.61), p=0.02. Serum IL-17A levels were also lower in the treatment group (3.974±1.06 pg/mL) than the control group (5.542±1.99 pg/ml), p=0.01. Discussion: Education as a non-pharmacological therapy is needed to reduce disease progression. Education is provided according to the patient's needs. Educational models can be offline (face to face) or online (digital). SEPO intervention in patients with knee osteoarthritis can reduce sodium intake, knee joint pain, and may impact on reduction of serum IL-17A.
Fast ions and hot electrons in the laser–plasma interaction

Data on the emission of energetic ions produced in laser–matter interactions have been analyzed for a wide variety of laser wavelengths, energies, and pulse lengths. Strong correlation has been found between the bulk energy per AMU for fast ions measured by charge cups and the x‐ray‐determined hot electron temperature. Five theoretical models have been used to explain this correlation. The models include (1) a steady‐state spherically symmetric fluid model with classical electron heat conduction, (2) a steady‐state spherically symmetric fluid model with flux limited electron heat conduction, (3) a simple analytic model of an isothermal rarefaction followed by a free expansion, (4) the lasnex hydrodynamics code [Comments Plasma Phys. Controlled Fusion 2, 85 (1975)], calculations employing a spherical expansion and simple initial conditions, and (5) the lasnex code with its full array of absorption, transport, and emission physics. The results obtained with these models are in good agreement with the experi.
Surgical Description of Laparoscopic Ovum Pick-Up in Buffalo Calves

Simple Summary In modern livestock, using calves as embryo donors is already a reality; thus, animal genetics can be transmitted before these animals have reached sexual maturity, considerably reducing the interval between generations. This fact becomes more relevant in buffalo species, as they present great inconsistency in the results of in vitro embryo production. This study is the first to describe a safe and effective surgical procedure for obtaining oocytes by laparoscopy in a farm environment using three surgical ports and transabdominal needle aspiration. Abstract The technique of laparoscopic oocyte aspiration has been increasingly used in animals; however, there are few records of its use in buffaloes. To describe this technique, six suckling Murrah buffaloes aged between 3 and 5 months were used. Three laparoscopic ovum pick-ups were performed in each animal, with intervals of 15 days between surgeries, completing a total of 18 procedures. The technique used three surgical ports with optics and a high-definition video camera. The introduction of the first portal and insufflation of the abdomen was performed through the open technique, with aspiration using a 20 G needle transabdominally and a vacuum pump calibrated at 50 mmHg. The mean complete surgical time from anesthesia to the removal of the animal from the litter was 49 ± 9.8 min. There were 27.8% cases of insufflation on the wrong side of the omentum. The oocyte recovery rate of 60.3% remained within the normal range. However, the rate of viable oocytes recovered was low, with only 40.8% of those recovered undergoing in vitro embryo production (IVEP). These data demonstrate that this simple, minimally invasive technique is an excellent reproductive tool for the genetic improvement of buffalo species.
High-angular-momentum Rydberg states in a room-temperature vapor cell for DC electric-field sensing

We prepare and analyze Rydberg states with orbital quantum numbers $\ell \le 6$ using three-optical-photon electromagnetically-induced transparency (EIT) and radio-frequency (RF) dressing, and employ the high-$\ell$ states in electric-field sensing. Rubidium-85 atoms in a room-temperature vapor cell are first promoted into the $25F_{5/2}$ state via Rydberg-EIT with three infrared laser beams. Two RF dressing fields then (near-)resonantly couple $25 \ell$ Rydberg states with high $\ell$. The dependence of the RF-dressed Rydberg-state level structure on RF powers, RF and laser frequencies is characterized using EIT. Furthermore, we discuss the principles of DC-electric-field sensing using high-$\ell$ Rydberg states, and experimentally demonstrate the method using test electric fields of $\lesssim$~50~V/m induced via photo-illumination of the vapor-cell wall. We measure the highly nonlinear dependence of the DC-electric-field strength on the power of the photo-illumination laser. Numerical calculations, which reproduce our experimental observations well, elucidate the underlying physics. Our study is relevant to high-precision spectroscopy of high-$\ell$ Rydberg states, Rydberg-atom-based electric-field sensing, and plasma electric-field diagnostics.
Vertical vibration of a circular footing on a linear-wave-velocity half-space

An exact treatment is presented for the problem of a rigid surface foundation vibrating vertically on an elastic half-space with a linear wave velocity profile. By means of a displacement-potential representation and integral transforms, the dynamic problem is formulated as a set of dual integral equations which are reducible to a Fredholm integral equation of the second kind. Numerical results are presented to illustrate the effects of the in situ inhomogeneity on the static and dynamic foundation responses. Characteristic features of the inhomogeneous half-space problem, such as the presence of local maxima in the dynamic foundation compliance functions and the existence of cut-off frequencies, are demonstrated. Les auteurs abordent le probleme de la vibration verticale de fondations a surface rigide surune masse e1astique semi-infinie a vitesse de propagation d'onde lineaire. A l'aide d'une representation du potentiel de deplacement et de transformations integrales, ils formulent le probleme dynamique .
Visible spectra and chromaticity of noctilucent clouds

A computational scheme was developed to predict the visible spectra and chromaticity of noctilucent clouds (NLC) for arbitrary viewing geometries. The spectrum of a cloud in the visible is computed at 5-nm intervals using the spherical shape of the stratified atmosphere, the measured solar irradiance spectrum, wavelength-dependent extinction by air molecules, ozone, and aerosols, and scattering by a specified size distribution of cloud particles. The chromaticity calculated from each spectrum is used to evaluate the cloud's color. A comparison is made of the abilities of two proposed cloud particle size distributions to account for published spectra measured from the ground and from Earth orbit. A lognormal distribution of “small” particles with an effective radius of 42.6 nm is found to be better at reproducing measured spectra of NLC than a Junge (power law) distribution of “large” particles with an effective radius of 700 nm. Chromaticities of the small-particle spectra show much better agreement with those of spectra measured from orbit and with the visual appearance of NLC viewed from the ground. Chromaticities are found to be weakly dependent on the atmospheric aerosol loading. However, NLC brightness is strongly dependent upon both tropospheric and stratospheric aerosols.
ENDOMORPHISM RINGS OF QUASI-PRINCIPALLY INJECTIVE MODULES

A right R-module M is called quasi-principally injective if every homomorphism from an M-cyclic submodule of M to M can be extended to M. Let M be a quasi-principally injective module which a self generator. In this paper we show that if such a module M has finite Goldie dimension, then S/J(S) is semisimple, where S = End(M R ). Furthermore if M is a self-generator quasi-principally injective module and M/soc(M) satisfies ACC on M-annihilator submodules, then J(S) is nilpotent. Some recent results obtained by Nicholson and Yousif are generalized.
A study of transverse normal stress effect on vibration of multilayered plates and shells

This paper evaluates transverse normal stress σzzeffect on vibration of multilayered structures. To this purpose a mixed plate model initially introduced by Toledano and Murakami has been extended to dynamics analysis of double curved shells. These models allow both continuous interlaminar transverse shear and normal stresses as well as the zigzag form of the displacement distribution in the shell thickness directions to be modelled. Governing equations have been derived by employing a Reissner's mixed theorem. Classical models on the basis of standard displacement formulations have been considered for comparison purposes. The evaluations of transverse stress effects have been conducted by comparing constant, linear and higher order distributions of transverse displacement components in the plate thickness directions. Free vibrational response of layered, simply supported plates, cylindrical and spherical shells made of isotropic as well as orthotropic layers has been analyzed. The numerical investigation carried out and comparison with earlier results has concluded that: • 1. The possibility of describing interlaminar continuous transverse normal stress makes the mixed theories more attractive with respect to other available modelling. • 2. Any refinements of classical models are meaningless, unless the effects of interlaminar continuous transverse shear and normal stresses are both taken into account in a multilayered shell theory.
Family Functioning is Associated with Post-Stroke Depression in First-Ever Stroke Survivors: A Longitudinal Study

Background Post-stroke depression (PSD) can aggravate the mortality and recurrence rate in stroke patients. The relationship between family functioning and PSD at different phases after a first-ever stroke is unclear. The purpose of this longitudinal study was to investigate the patterns and relationship of family functioning and PSD at acute hospitalization and 6 months post-discharge in first-ever stroke survivors. Methods This is a longitudinal study conducted in Guangzhou, China. Family functioning and depression were measured by the Short Form Family Assessment Device (SF-FAD) and Self-Rating Depression Scale (SDS) at baseline and 6 months post-discharge. Multiple linear regression analysis was used to explore the relationship between family functioning and PSD. Results The prevalence of PSD at acute hospitalization and 6 months post-discharge was 32.9% and 20.0%, respectively. SDS scores decreased significantly from baseline to 6 months post-discharge, while SF-FAD scores did not change significantly during this period. The Pearson correlation coefficient showed that SF-FAD scores were positively associated with SDS scores at the two time points (r1 = 0.341, r2 = 0.510, P < 0.05). Multiple linear regression analyses indicated that SF-FAD scores could predict PSD at baseline (unstandardized coefficient: 7.010, P < 0.05) and 6 months post-discharge (unstandardized coefficient: 9.672, P < 0.001). Conclusion This study found that first-ever stroke survivors had good family functioning at baseline and 6 months post-discharge. The findings in this study verified that poor family functioning is positively associated with PSD at different phases post-stroke. Good family functioning is an important protective factor against PSD.
The impact of internal green marketing on managers' organizational identification and financial performance of organizations of the agribusiness sector in Serbia

The purpose of the paper was to examine the impact of internal green marketing on managers' organizational identification and the financial performance of the organizations. The empirical research was carried out by an online survey. The model proposed in this paper was tested on a sample of 53 managers of Serbian organizations in the agribusiness sector. For empirical testing of the proposed hypotheses, partial least squares structural equation modeling was used. The findings revealed that the direct effect of internal green marketing on managers' organizational identification as well as the direct effect of managers' organizational identification on financial performance is positive and statistically significant. Managers' organizational identification fully mediates the relationship between internal green marketing and financial performance. This paper can contribute to better understanding of green internal marketing and its effect on organizations, especially in the agribusiness sector. The results can be useful to managers in the agribusiness sector.
Heat Transfer from Circular Cylinders at Low Reynolds Numbers. I. Theory for Variable Property Flow

The low Reynolds number flow past a heated infinite cylinder is studied for cases involving significant variation of fluid properties, and when thermal and velocity slip is present at the wall. Initially, the inner and outer asymptotic expansions for the flow field variables are derived for an arbitrary thermal conductivity‐temperature relationship. The corresponding Nusselt number, developed in terms of the expansion parameter e = [ln (4/RePr) − γ + β]−1 (where Re is the Reynolds number, Pr is the Prandtl number, γ is the Euler's constant and β is the thermal slip parameter), is valid to order e3. For the special case λ = Tω an explicit relationship Nu = Nu (Re, Pr, τ, ω, β) is given, where τ = (T′w − T′∞)/T′∞. It is shown that the continuum and slip Oseen‐type analyses of Cole and Roshko, and Levey, respectively, are zeroth‐order approximations for the Nusselt number in the limit τ → 0. The zeroth‐order drag coefficient is also given in the form CDo = CDo(Re, τ, ω, f), where f is the velocity slip par.
Magneto-atmospheric waves subject to Newtonian cooling

We present a new class of analytic solutions for linear magneto-atmospheric waves in a stratified, isothermal atmosphere. This new class spans from the solutions found by Yu (1965) for a constant Alfven speed atmosphere to those of Nye & Thomas (1976a,b) for an atmosphere with exponentially increasing Alfven speed. The inclusion of radiative dissipation in magneto-atmospheric wave problems - even in the over-simplified Newtonian cooling approximation - is of great importance in many applications. We show how the effects of Newtonian cooling can be incorporated in any isothermal magneto-atmospheric wave problem by letting the ratio of specific heats, γ, be a complex, frequency dependent quantity. This technique is discussed in the context of the new solutions presented here
Contextual Data Augmentation for Task-Oriented Dialog Systems

Collection of annotated dialogs for training task-oriented dialog systems have been one of the key bottlenecks in improving current models. While dialog response generation has been widely studied on the agent side, it is not evident if similar generative models can be used to generate a large variety of, and often unexpected, user inputs that real dialog systems encounter in practice. Existing data augmentation techniques such as paraphrase generation do not take the dialog context into consideration. In this paper, we develop a novel dialog augmentation model that generates a user turn, conditioning on full dialog context. Additionally, with a new prompt design for language model, and output re-ranking, the dialogs generated from our model can be directly used to train downstream dialog systems. On common benchmark datasets MultiWoZ and SGD, we show that our dialog augmentation model generates high quality dialogs and improves dialog success rate by as much as $8\%$ over baseline.
Resveratrol Attenuates Sepsis-Induced Cardiomyopathy in Rats through Anti-Ferroptosis via the Sirt1/Nrf2 Pathway

Abstract Background: Sepsis-induced cardiomyopathy (SIC) is a severe myocardial dysfunction secondary to septicemia. It is a major concern owing to the high mortality and morbidity, which are greatly influenced by ferroptosis. Resveratrol (RSV) is a naturally existing agonist of the silent information regulator 1 (Sirt1). It has cardioprotective effects against sepsis-induced myocardial injury, However, the detailed mechanism is unknown. Methods: In this study, cecal ligation and puncture (CLP)-induced septic rats were employed to assess the changes in ferroptosis with RSV administration. According to the different treatments the rats were divided into the following groups: (1) the Sham, (2) CLP, (3) CLP + RSV at various doses (10, 30, and 50 mg/kg), and (4) CLP + Fer-1(a ferroptotic inhibitor) groups. After 24 h, the structure and function of the cardiac system in rats were evaluated, and mitochondrial morphology, ferroptosis-related biomarkers, and the levels of Sirt1/Nrf2 were assessed. Results: The rats that underwent CLP had suffered cardiac dysfunction, accompanied with myocardial damage, impaired mitochondria, elevated lipid peroxidation, and reduced Sirt1/Nrf2 expression in the myocardium. High-dose RSV successfully improved heart function, reversing the abnormalities in a dose-dependent manner. We then used EX527, a selective Sirt1 inhibitor, to further identify the intermediate signaling targets of RSV that regulate ferroptosis. EX527 diminished the curative effects of high-doses RSV. Conclusions: Summarily, our findings suggest a novel mechanism of RSV in reducing SIC: ferroptosis inhibition via upregulation of Sirt1/Nrf2 signaling pathways. This may be an effective therapeutic approach against organ failure in sepsis, particularly SIC.
