Abstract Background Impact of recurrent pericarditis (RP) on patient health-related quality life (HRQoL) was evaluated through qualitative interviews and as an exploratory endpoint in a Phase 2 trial evaluating the efficacy safety rilonacept (IL-1?/IL-1? cytokine trap) to treat RP. Methods Qualitative were conducted with ten adults RP understand symptoms HRQoL impacts, 10-item Patient-Reported ...
در این مقاله وجود پایداری در نرخ تورم ایران آزمون میشود. برای این منظور، درجه انباشتگی کسری، با استفاده از روشهای GPH، تعدیل رابینسون، ریزن، وایتل و موجکها و با استفاده از دادههای بانک مرکزی در مورد شاخص قیمت مصرف کننده سالهای 1351-1390، تخمین زده شد. نتایج حاصل از تحقیق، بیانگر وجود پایداری در نرخ تورم ایران است. وجود ایستایی و پایداری نرخ تورم در اقتصاد، بیانگر این است که در صورت بروز یک...
The standing spin wave resonance has been measured in thin films of EuS at 1.1 OK in the perpendiculai configuration. The magnon dispersion relation is found to be quadratic in the observed region of k (k < 0.2 xla). The effective exchange energy (JI $. Jz) determined is 0.088 f 0.010 OK. This value is lower than that calculated by Passenheim et al. [7] from specific heat measurements. This dis...
A major issue in nancial economics is the behaviour of stock returns over long horizons. This study provides empirical evidence of the long-range behaviour of various speculative returns. Using di erent techniques such as R=S and modi ed R=S analysis, detrended uctuation analysis (DFA), fractional di erencing test (GPH) and ARFIMA maximum likelihood estimation, we nd little evidence of long mem...
Humor is an advanced emotional and cognitive ability of mankind that involves complex semantic inference and deep passionate appreciation. This paper presents the cognitive foundations of amusement and a general theory of humor based on the recent advances in cognitive informatics, cognitive linguistics, cognitive computing, and fuzzy causal analyses. A theory of fuzzy false causation (FFC) is ...
A laser ablation device in combination with a molecular beam Fourier-transform microwave spectrometer has allowed the observation of the rotational spectrum of serotonin for the first time. Three conformers of the neurotransmitter have been detected and characterized in the 4-10 GHz frequency range. The complicated hyperfine structure arising from the presence of two (14)N nuclei has been fully...
This research aims to introduce an ideal model for forecasting Iranian crude oil price movements. It tries to make an all-out analysis of this energy product. Therefore, we tested the ‘predictability’ hypothesis by using the variance ratio test, BDS test and the chaos series test. Later, a structural analysis is a carried out to investigate possible nonlinear patterns in the series. Lyapunov ex...
دادههای با تناوب بالا نوع خاصی از نامانایی دارند که به آن نامانایی کسری گفته میشود. این ویژگی سبب پدیدآمدن حافظه بلندمدت در سریهای زمانی مالی با تناوب بالا میشود. در این نوشتار ابتدا وجود حافظه بلندمدت در سری زمانی صنعت سیمان بررسی شده و وجود آن در سطح اطمینان بالایی توسط دو آزمون R/S و GPH تأیید میشود. در ادامه، دقت مدلهای پیشبینی سریهای زمانی مالی نظیر، ARMA و GARCH که ویژگی حافظه بلن...
Abstract The need for quality water in Africa agriculture cannot be underemphasized amidst the current global crises. focus of this study sought to evaluate groundwater irrigation purposes while unearthing emerging challenges area. In total, 202 samples were collected, and several parameters tested. employed QGIS multi-criteria decision analysis examine zones suitable agriculture. Findings from...
AIMS Orthostatic hypotension (OH), an independent predictor of mortality and cardiovascular events, strongly correlates with hypertension. Recent genome-wide studies have identified new loci influencing blood pressure (BP) in populations, but their impact on OH remains unknown. METHODS AND RESULTS A total of 38 970 men and women of European ancestry from five population-based cohorts were inc...
