The response of the competitive balance model to the external field

The competitive balance model was proposed as an extension of the balance theory to address heterogeneities in real-world networks. In this model, different paradigms lead to form different friendship and enmity. As an example, friendship or enmity between countries can have a political or religious basis. The suggested Hamiltonian is symmetrical between paradigms. In this paper, we investigate the influence of the external field on the evolution of the network. We drive the mean-field solutions of the model and verify the accuracy of our analytical solutions by performing Monte-Carlo simulations. We observe that the external field breaks the symmetry of the system. The response of the system to the external field, depending on the temperature, is paramagnetic or ferromagnetic. Similar to the magnetic systems, susceptibility follows Curie's law. We also observed a hysteresis behavior. Once communities are formed based on a certain paradigm, then they resist change.Comment: 24 pages, 6 figure

The structure of gene-gene networks beyond pairwise interactions

Despite its high and direct impact on nearly all biological processes, the underlying structure of gene-gene interaction networks is investigated so far according to pair connections. To address this, we explore the gene interaction networks of the yeast Saccharomyces cerevisiae beyond pairwise interaction using the structural balance theory (SBT). Specifically, we ask whether essential and nonessential gene interaction networks are structurally balanced. We study triadic interactions in the weighted signed undirected gene networks and observe that balanced and unbalanced triads are over and underrepresented in both networks, thus beautifully in line with the strong notion of balance. Moreover, we note that the energy distribution of triads is significantly different in both essential and nonessential networks compared with the shuffled networks. Yet, this difference is greater in the essential network regarding the frequency as well as the energy of triads. Additionally, results demonstrate that triads in the essential gene network are more interconnected through sharing common links, while in the nonessential network they tend to be isolated. Last but not least, we investigate the contribution of all-length signed walks and its impact on the degree of balance. Our findings reveal that interestingly when considering longer cycles the nonessential gene network is more balanced compared to the essential network.Comment: 16 pages, 5 figures, 4 table

Religious attitudes and spiritual health among elderly inpatient adults in Shahrekord hospitals

Background and Objectives: Human is a multidimensional creature and spiritual domain is the central dimension which has an undeniable effect on gaining health. The most important part of nursing care with family based approach is to help people in achieving optimal level of health. On the other hand, religious attitudes and spiritual health is an important domain of life in ageing period. Therefore, this study was conducted to assess the religious attitudes and spiritual health among elderly inpatients in Shahrekord hospitals. Methods: This descriptive correlational study was conducted in 1392 in Shahrekord hospitals. A total of 308 geriatric patients who were admitted to a surgical ward, were recruited through random sampling. Two sets of questionnaires regarding religious and spiritual health were used as the instruments. After collecting the data, descriptive (frequency, mean, variance, standard deviation) and analytical (independent t test, Pearson correlation) statistics were used by SPSS statistical software. Results: The results showed that 68.8% of patients possessed large religious attitude with an average of 140.68 ±30.14. Spiritual health in 51.3 percent of samples was described to be low while the obtained average score was 86.18 ± 16.61. However, Pearson test showed that there is a positive significant correlation between religious attitudes and spiritual health (r =0.83, P =0.05). Conclusions: The present study revealed that there is a significant relationship between religious attitudes and spiritual health and people with high religious attitudes have high spiritual health

Coupled criticality analysis of inflation and unemployment

In this paper, we are interested to focus on the critical periods in the economy which are characterized by large fluctuations in macroeconomic indicators. To capture unusual and large fluctuations of inflation and unemployment, we concentrate on the non-Gaussianity of their distributions. To this aim, by using the coupled multifractal approach, we analyze US data for a period of 70 years from 1948 until 2018 and measure the non-Gausianity of the distributions. Then, we investigate how the non-Gaussianity of the variables affects the coupling structure of them. By applying the multifractal method, one can see that the non-Gaussianity depends on the scales. While the non-Gaussianity of unemployment is noticeable only for periods smaller than 1 year and for longer periods tends to Gaussian behavior, the non-Gaussianities of inflation persist for all time scales. Also, it is observed that the coupling structure of these variables tends to a Gaussian behavior after $2$ years.Comment: 13 pages, 3 figure

The effect of educational- counseling program on general health of women as caregivers of patient, with Alzheimerdisease

زمینه و هدف: ارائه مراقبت طولانی مدت به بیماران مبتلا به آلزایمر، با افزایش خطرات ابتلا به بیماری جسمی و روانی برای مراقبین همراه است و فقدان تعلیمات لازم نیز مشکلات سلامتی آنها را دو چندان نموده است. این مطالعه با هدف تعیین تاثیر برنامه آموزشی- مشاوره ای بر سلامت عمومی زنان مراقبت کننده از سالمندان مبتلا به آلزایمر انجام شده است. روش بررسی: در این پژوهش تجربی، 150 زن 18 تا 60 ساله که از وابستگان درجه یک سالمندان مبتلا به آلزایمر بوده و مراقبت مستقیم از آنها را به مدت حداقل 6 ماه به عهده داشتند، با روش نمونه گیری آسان انتخاب شدند و پس از انجام پیش آزمون شامل پرسشنامه اطلاعات دموگرافیک و سلامت عمومی گلدبرگ، با روش تصادفی بلوکه شده، به شکل تصادفی در دو گروه آزمون و کنترل قرار گرفتند. گروه آزمون در یک برنامه آموزشی – مشاوره ای شامل یک جلسه بحث گروهی، دریافت یک پمفلت آموزشی و دو مشاوره تلفنی شرکت نمودند. 6 هفته پس از مداخله، پس آزمون برای هر دو گروه انجام گرفت. برای مقایسه متغیرها از آزمون های آماری t زوجی، t مستقل، کای اسکوئر و آنالیز واریانس یک طرفه استفاده شد. یافته ها: نتایج نشان داد که قبل از برنامه آموزشی- مشاوره ای 3/17 از نمونه های مورد پژوهش سلامت عمومی نامطلوب داشتند. پس از انجام برنامه آموزشی- مشاوره ای میانگین سلامت عمومی در گروه آزمون از 3/15±68/39 به 03/10±09/19 تقلیل یافت (001/0

Deciphering the Exceptional Performance of NiFe Hydroxide for Oxygen Evolution Reaction in Anion Exchange Membrane Electrolyzer

Hydrogen production via water electrolysis with renewable electricity as input will be crucial for the coming defossilized energy age. Herein, we report an anion exchange membrane electrolyzer using Fe-doped Ni hydroxide as anode catalyst that is on par with proton exchange membrane electrolyzers in terms of performance, 2 A cm-2 at 2.046 V and 50 °C. We found that Fe-doping stabilizes the alfa-Ni(OH)2 phase which is key to ensure the fast Ni(OH)2/NiOOH redox transition and the subsequent fast reaction between Ni3+/4+ and the electrolyte (OH-), resulting in the excellent oxygen evolution reaction activity of Fe-doped Ni hydroxide. Spin-polarized DFT+U computations reveal that the local arrangement of Fe3+ with Ni3+/4+ plays a crucial role in enabling the high OER activity on (001) facet of this anode catalyst
