A Five-Band Study of Spiral Galaxies: X-Ray, Optical, Near- and Far-Infrared, and Radio Continuum Correlations

A statistical analysis is given of the relationships between global emission properties of spiral galaxies, including the radio continuum, far-infared, near-infrared H-band, optical (B), and X-ray emission. Different properties are observed in early-type and in late-type spiral galaxies, which can be ascribed to the presence of prominent bulges in the former. In late-type spirals, the statistical properties of the emission at different wavelengths are consistent with a common disk/arm origin. The power-law exponents of the correlations are consistent with a steeper IMF in low-luminosity galaxies and with the presence of an obscured starburst component in high-luminosity galaxies. The strongest correlation of the radio continuum luminosity with any other variable is with the far-infrared, suggesting that the radio emission is disjoint from the older low-mass stellar component.
Stress and resilience during pregnancy: A comparative study between pregnant and non-pregnant women in Ethiopia

Background Stress during pregnancy is associated with perturbances in maternal psychology and physiology, and results in adverse pregnancy and birth outcomes. However, little attention has been given to understand maternal stress and its potential negative consequences in many low- and middle-income countries. We aimed to investigate whether pregnancy is associated with greater stress and lower psychological resilience among women living in Jimma, Southwest Ethiopia. Method An institution-based comparative cross-sectional study design was implemented in Jimma University Medical Center and Jimma health centers from 15 September to 30 November 2021. Women attending antenatal care and family planning services were invited to participate in the study. Participants were interviewed using the Perceived Stress Scale (PSS-10), Brief Resilience Scale (BRS), distress questionnaire-5, and the Household Food Insecurity Access Scale (HFIAS). Linear regression analysis was used to test associations between pregnancy (exposure) and outcomes of interest (stress and resilience scores), while adjusting for potential confounders. Stress and resilience were mutually adjusted for one another in the final model. Results A total of 166 pregnant and 154 non-pregnant women participated, with mean age of 27.0 SD 5.0 and 29.5 SD 5.3 years respectively. Pregnancy was associated with increased stress score by 4.1 points (β = 4.1; 95% CI: 3.0, 5.2), and with reduced resilience by 3.3 points (β = -3.3; 95% CI: -4.5, -2.2) in a fully adjusted model. In mutually-adjusted models, pregnancy was independently associated with greater stress (β = 2.9, 95% CI 1.8, 3.9) and lower resilience (β = -1.3, 95% CI: -2.5, -0.2) compared to non-pregnant women. Conclusion In this low income setting, pregnancy is associated with greater vulnerability in the mental health of women, characterized by greater perceived stress and diminished resilience. Context-relevant interventions to improve resilience and reduce stress could help improve the health and wellbeing of mothers, with potential benefits for their offspring.
Efficient Approximate Techniques for Integrating Stochastic Differential Equations

Abstract The delicate (and computationally expensive) nature of stochastic numerical modeling naturally leads one to look for efficient and/or convenient methods for integrating stochastic differential equations. Concomitantly, one may wish to sensibly add stochastic terms to an existing deterministic model without having to rewrite that model. In this note, two possibilities in the context of the fourth-order Runge–Kutta (RK4) integration scheme are examined. The first approach entails a hybrid of deterministic and stochastic integration schemes. In these examples, the hybrid RK4 generates time series with the correct climatological probability distributions. However, it is doubtful that the resulting time series are approximate solutions to the stochastic equations at every time step. The second approach uses the standard RK4 integration method modified by appropriately scaling stochastic terms. This is shown to be a special case of the general stochastic Runge–Kutta schemes considered by Ruemelin and h.
An immersed finite element space and its approximation capability

This article discusses an immersed finite element (IFE) space introduced for solving a second‐order elliptic boundary value problem with discontinuous coefficients (interface problem). The IFE space is nonconforming and its partition can be independent of the interface. The error estimates for the interpolation of a function in the usual Sobolev space indicate that this IFE space has an approximation capability similar to that of the standard conforming linear finite element space based on body‐fit partitions. Numerical examples of the related finite element method based on this IFE space are provided. © 2004 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq 20: 338–367, 2004
Sampling and reconstruction in shift-invariant spaces on R d

Let φ ∈ W ( C , (cid:3) 1 ) such that { τ n φ : n ∈ Z d } forms a Riesz basis for V (φ) . It is shown that Z d is a stable set of sampling for V (φ) if and only if (cid:5) † ( x ) (cid:3)= 0, for every x ∈ T d , where (cid:5) † ( x ) := (cid:2) n ∈ Z d φ( n ) e 2 π in · x , x ∈ T d . Sampling formulae are provided for reconstructing a function f ∈ V (φ) from uniform samples using Zak transform and complex analytic technique. The problem of sampling and reconstruction is discussed in the case of irregular samples also. The theory is illustrated with some examples, and numerical implementation for reconstruction of a function from its nonuniform samples is provided using MATLAB.
A Coronal Spectrum in the 500-1610 Å Wavelength Range Recorded at a Height of 21,000 Kilometers above the West Solar Limb by the SUMER Instrument on Solar and Heliospheric Observatory

We present a solar coronal spectrum recorded by the extreme UV spectrometer SUMER on the Solar and Heliospheric Observatory. The spectrum was taken between 21:28 UT on 1996 June 25 and 02:47 UT on 1996 June 26, at a height of 21,000 km above the west equatorial limb with the slit oriented in the north-south direction. At the time of the observations the Sun was rather quiet, and the west limb appeared "devoid of any activity. " The spectrum, which covers the 500-1610 Å wavelength range, originates from plasmas with temperatures ranging between 1.5 × 104 and 1.5 × 106 K. Identification of lines originating from different temperature regimes is facilitated by the appearance of their intensity along the 300'' long slit. Well over 800 lines have been found, many of which were not previously observed. We present the entire spectrum and discuss line identifications. A table of the wavelengths of lines observed, with their identifications and peak intensities, is provided. Although we have identified lines previously detected in laboratory plasmas and a number of new lines not previously observed, over 40% of the SUMER lines remain unidentified. Among the newly detected lines, some have a potential as plasma density diagnostics.
Full theory of speckle displacement and decorrelation in the image field by wave and geometrical descriptions and its application in mechanics

Abstract The paper describes the possibility of using the speckle pattern decorrelation for determination of small deformation tensor components of an elementary object surface area in an optical image field. The relationship between the small-deformation tensor and the speckle field displacement is analysed in detail. The studied problem is presented from the approximation viewpoint of both wave and geometrical optics.
Classification and Concept Consistency

This article investigates the extent to which undergraduates consistently use a single mechanism as a basis for classifying mathematical objects. We argue that the concept image/concept definition distinction focuses on whether students use an accepted definition but does not necessarily capture the more basic notion that there should be a fixed basis for classification. We examine students’ classifications of real sequences before and after exposure to definitions of increasing and decreasing; we develop an abductive plausible explanations method to estimate the consistency within the participants’ responses and suggest that this provides evidence that many students may lack what we call concept consistency. RésuméCet article analyse jusqu’à quel point les étudiants se servent systématiquement d’un seul mécanisme comme base pour la classification des objets mathématiques. Selon nous, la distinction entre image du concept et définition du concept permet de déterminer si les étudiants utilisent une définition reconnue, mais elle ne reflète pas nécessairement l’idée plus fondamentale que la classification doit se faire sur la base de certains critères fixes. Nous analysons la classification des séquences réelles de la part des étudiants avant et après leur formation sur la définition des concepts de ‘croissant’ et ‘décroissant’. En outre, nous élaborons une méthode inductive ‘d’explications plausibles’ pour apprécier la cohérence logique des réponses des participants, et les résultats indiquent que de nombreux étudiants manquent de ce qu’on pourrait appeler ‘cohérence du concept’.
Modelling and simulation of nozzle ablation in high-voltage circuit-breakers

In the present paper, a new approach to modelling the ablation phenomenon using computational fluid dynamics (CFD) tools coupled with a physical radiation model is proposed, implemented and validated for application in circuit-breaker arc studies. The present work shows that the principal characteristics of ablation-dominated arcs can be simulated effectively using CFD tools if the radiation incident at the wall boundaries can be predicted accurately.
Interaction at the primary–secondary care interface: Patients’ and physicians’ perceptions of teleconsultations

Introduction Previous qualitative research on teleconsultations has focused on synchronous communication between a patient and a clinician. This study aims to explore physicians' and patients' perceptions of the interaction on the interface between primary care and the Cardiology service of a referral hospital through teleconsultations. Methods This qualitative study was embedded in an organizational case study concerning the introduction and rollout of a new service model that took place at the point of care. The patients and physicians were recruited for semi-structured interviews until thematic saturation was achieved, between September 2019 - January 2020. The interviews were audiorecorded and anonymized. The transcribed interviews were stored, coded, and analyzed in MAXQDA, following the steps for conventional content analysis. Results A total of 29 participants were interviewed. Patients and physicians presented clear views about the role of the GP and the cardiologist and their function in overall structure of healthcare. GPs felt their role was to bring expertise in the patient which could supplement the cardiologists' expertise on the condition. However, GPs had to renegotiate roles in the teleconsultations when they saw themselves in a new situation, together with another physician and the patient. Conclusions Our findings suggest that joint teleconsultations can promote continuity of care for patients in the primary/secondary care interface. Active coordination between physicians with delineation of roles throughout primary-secondary care interface is needed to manage selected patients who may benefit the most from shared care.
Knowledge, Attitude and Practice of Pharmacy Professionals Against Dispensing Antibiotics Without Prescription in Ethiopia

Introduction Antibiotic resistance is a global public health threat that warrants immediate intervention. Dispensing of antibiotics without prescription (DAWP), is an inappropriate practice that contributes significantly to the emergence and spread of antibiotic resistance. The current study aimed to assess the knowledge, attitude and practice of community pharmacists and pharmacy assistants towards DAWP. Methods A cross-sectional study was conducted, and data was collected from community pharmacists and pharmacy assistants during the eighth national pharmacist’s day, which was held on December 4, 2021, in Addis Ababa, Ethiopia. A pre-tested self-administered questionnaire comprise of four sections (socio-demographic characteristics, and knowledge, attitude and practice towards DAWP) was used. The data was analyzed using SPSS version 26 and descriptive statistics (mean, percentage, standard deviation) were computed. Binary logistic regression was used to predict determinates of DAWP. Results A total of 175 community pharmacy professional were invited in the study, with 158 (111 pharmacists and 47 pharmacy assistants) completing the survey for 90.3% response rate. Most of the participants (86.7%) were aware that DAWP is illegal in Ethiopia. Despite their knowledge, the extent of DAWP was found to be 67.7%. The most common reason given by study participants for DAWP was that most patients do not want to consult prescribers unless the infection appears serious (53.2%). Pharmacy professionals with educational background of masters and above (AOR= 0.354, 95% CI: 0.013–0.744, P= 0.045), and with two to five years of working in community pharmacy (AOR= 0.745, 95% CI: 0.595–0.933, P= 0.010) had a lower tendency to DAWP, respectively. Conclusion Despite majority of pharmacy professional are aware that DAWP is illegal and contributes to antibiotic resistance, they commonly DAWP for common cold and diarrheal diseases. Strict enforcement of existing antibiotic supply policies, and ongoing educational support for community pharmacy professionals on the judicious use of antibiotics is recommended.
Non-Small Cell Lung Cancer with Malignant Pleural Effusion May Require Primary Tumor Radiotherapy in Addition to Drug Treatment

Purpose The impact of primary tumour radiotherapy on the prognosis for non-small-cell lung cancer (NSCLC) with controlled malignant pleural effusion (MPE-C) (MPE-C-NSCLC) is unclear. This study aimed to analyze the efficacy and safety of primary tumor radiotherapy in patients with MPE-C-NSCLC. Patients and Methods A total of 186 patients with MPE-C-NSCLC were enrolled and divided into two groups. The patients in the D group were treated with only drugs. Those in the RD group were treated with drugs plus primary tumour radiotherapy. The Kaplan-Meier method was used for survival analysis, and the Log rank test was used for between-group analysis and univariate prognostic analysis. The Cox proportional hazards model was used to perform multivariate analyses to assess the impacts of factors on survival. Propensity score matching (PSM) was matched based on clinical characteristics, systematic drug treatment and drug response to further adjust for confounding factors. Results The overall survival (OS) rates at 1, 2, and 3 years for the RD group and D group were 54.4%, 26.8%, and 13.3% and 31.1%, 11.5%, and 4.4%, respectively; the corresponding MSTs were 14 months and 8 months, respectively (χ2=15.915, p<0.001). There was a significant difference in survival by PSM (p=0.027). Before PSM, multivariate analysis showed that metastasis status (organ≤3 and metastasis≤5), primary tumour radiotherapy, chemotherapy cycles≥4, and drug best response (CR+PR) were independent predictors of prolonged OS. After PSM, primary tumour radiotherapy and drug best response (CR+PR) were independent predictors of prolonged OS were still independent predictors of prolonged OS. There were no grade 4–5 radiation toxicities. Conclusion For MPE-C-NSCLC, the response of systemic drug treatment plays a crucial role in survival outcomes, and we also should pay attention to primary tumour radiotherapy in addition to systematic drug treatment.
Risk factors associated with chronic kidney disease progression: Long-term retrospective analysis from Qatar

Introduction: The risk factors influencing the natural course of chronic kidney disease (CKD) are complex and heterogeneous. Recognizing the factors associated with CKD progression can enable the identification of high-risk patients for more intensive treatment. Patients and methods: A retrospective evaluation of CKD patients was performed under follow-up between January 1, 2001 and December 31, 2016 at a tertiary health care center. Results: Among 5370 screened patients, 1020 patients with complete data were included in the analysis. The median follow-up period for the studied patients was 9.3 years. Based on the analysis, 120 (11.8%) patients had reached end-stage kidney disease “ESKD” or death. The study revealed that the risk factors associated with reaching ESKD and/or death using Kaplan–Meier survival curve and log rank test included higher hemoglobin A1c among diabetic patients, higher grade of proteinuria, and non use of renin-angiotensin system blockers. The patients with CKD progression constituted 77.2% of all CKD patients. The study findings indicated that older age, Arab ethnicity, smoking habit, diabetes mellitus and hypertension (presumed as original kidney diseases) are among the significant risk factors associated with a further decline of the estimated glomerular filtration rate (eGFR) and further CKD progression. Conclusion: This study summarized the demographic and clinical risk factors associated with CKD progression and patients’ outcomes among a unique and heterogeneous population in the state of Qatar. Intensive treatment of modifiable risk factors could be of value in halting the progression of CKD. However, prospective studies are warranted to confirm our findings.
Magnetic, transport, and optical properties of monolayer copper oxides

The authors review the results of a wide variety of experiments on materials such as La{sub 2}CuO{sub 4} and Nd{sub 2}CuO{sub 4} that contain weakly coupled CuO{sub 2} layers. These materials are antiferromagnetic insulators with very large Heisenberg exchange energies, which become high-temperature superconductors when charge carriers are added to the CuO{sub 2} layers. The growth of large single crystals has made it possible to carry out neutron scattering, as well as anisotropic optical, transport, and magnetization measurements. The properties of the undoped CuO{sub 2} layer are reviewed, and the evolution of magnetic, optical, and transport properties with the addition of charge carriers is discussed. The emphasis is on the pure and lightly doped materials, although the magnetism in the superconductors is discussed. {copyright} {ital 1998} {ital The American Physical Society}
The Effect of Home-Based Dichoptic Therapy on Young Adults with Non-Strabismic Anisometropic Amblyopia on Stereo Acuity

Aim To evaluate the effect of home-based dichoptic visual therapy using anaglyphic red-green filters on the stereo acuity in a sample of young adults with non-strabismic anisometropic amblyopia. Methods The study was observational and cross-sectional in design. Two groups (experimental vs control) were sourced using purposive sampling of young adults with non-strabismic amblyopia (experimental group) in comparison to an age-match control group without amblyopia. For the purpose of refractive adaptation, all participants in both groups were asked to wear their spectacle correction constantly for at least 16 weeks prior to exposure to home-based dichoptic therapy. Stereo acuity measurements using the Stereo Fly test were obtained before and after 40 hours exposure to home-based dichoptic therapy. The changes in stereo acuity post eight weeks (40 hours) training from baseline measurements was obtained. The difference in medians between the experimental and control groups using the Mann–Whitney U-test was measured with significance set at P value of <0.05. Results A total of 38 young adults (19 males, 19 females) with a mean age of 24.05 ± 5.66 years were enrolled in this study. Nineteen anisometropic amblyopes comprised the experimental group, fifteen of which were classified as moderate amblyopia (6/12-6/36) and 19 non-amblyopes comprised the control group. Home-based dichoptic therapy used on the experimental group after 8 weeks showed a significant improvement in stereo-acuity with a mean improvement of 345.26 ± 184.85 sec arc−1 [IQR:260;600; p<0.001] when compared to the control group. Conclusion Home-based dichoptic therapy improved stereo-acuity in non-strabismic anisometropic amblyopes (moderate) in young adults. Thus suggesting that binocularity can improve in anisometropic adult amblyopes with a treatment modality that may be a convenient option better suit the demanding lifestyle of economically active adults who may not be able to comply with clinic-based therapy.
Pathological Features of Ovarian Tumors, Diagnosed at a Tertiary Care Hospital in Afghanistan: A Cross-sectional Study

Purpose In Afghanistan, research work is still in its infancy and there is no national level tumor registry at the moment in the country that could elaborate the histopathological features of ovarian tumors in the country. The current study was conducted with the aim to describe pathological characteristics of ovarian tumors diagnosed at tertiary level in Afghanistan. Patients and Methods A descriptive cross-sectional study was conducted, including 198 cases diagnosed with ovarian tumors, that were consecutively included in the study from July 2017 to August 2020. All the cases were diagnosed at the Department of Pathology, French Medical Institute for Mothers and Children, Kabul, Afghanistan, that receives biopsy samples from all of the tertiary care institutions in Kabul. Results In the current study, majority of the ovarian tumors were benign and presented with nonspecific symptoms. The mean age at diagnosis was 34.4 (SD ±13.4). Benign tumors comprised 81.8%, borderline 1.5% and malignant 16.7% of the cases. Majority of the diagnosed tumors were from surface epithelium in origin, followed by germ cell tumors, sex cord stromal tumors, and a single metastatic tumor. The most common benign neoplasm was mature cystic teratoma, followed by benign serous cystadenoma. Considering the malignant tumors, serous cystadenocarcinoma and adult granulosa cell tumors were predominant, followed by endometrioid adenocarcinoma and mucinous cystadenocarcinoma. More than half of the ovarian tumors occurred between 21 and 40 years of age. Conclusion In the current study, the proportion of malignant ovarian neoplasms was significantly less than benign lesions. Although, many of the pathological features related to ovarian neoplasms were similar to the features demonstrated in other regions of the world, there were important findings that were exclusively noted in the cases diagnosed in Afghanistan.
