Reproducibility is imperative for any scientific discovery. More often than not, modern scientific findings rely on statistical analysis of high-dimensional data. At a minimum, reproducibility manifests itself in stability of statistical results relative to “reasonable” perturbations to data and to the model used. Jacknife, bootstrap, and cross-validation are based on perturbations to data, whi...

BACKGROUND The health-related quality of life (HRQoL) is currently weighted more heavily when evaluating health status, particularly regarding medical treatments and interventions. However, it is rarely used by physicians to compare responsiveness. Additionally, responsiveness estimates derived by the Harris Hip Score (HHS) and the Short Form 36 (SF-36) before and after revision total hip arthr...

The SF-36 Physical Component Summary (PCS) and the Measure Yourself Medical Outcome Profile (MYMOP) are respectively generic and individualised self-report tools to assess health. The aim of this study was to compare responsiveness to change in these outcomes among patients with musculoskeletal problems referred for physiotherapy. Data were collected at baseline, 6 weeks and 6 months from 3714 ...

The goal of this study was the evaluation of agriculture parcel area measurement accuracy on Cartosat-1 imagery, and the determination of the technical tolerance appropriate for measurement using photointerpretation techniques. A further objective was to find out the influence of image type, land cover or parcel size on the area measurement variability. In our experiment, five independent opera...

The Disrupted in Schizophrenia Gene 1 (DISC1) plays a role in both neural signaling and development and is associated with schizophrenia, although its links to altered brain structure and function in this disorder are not fully established. Here we have used structural and functional MRI to investigate links with six DISC1 single nucleotide polymorphisms (SNPs). We employed a brain-wide associa...

Since the importance of DNA-binding proteins in multiple biomolecular functions has been recognized, an increasing number of researchers are attempting to identify DNA-binding proteins. In recent years, the machine learning methods have become more and more compelling in the case of protein sequence data soaring, because of their favorable speed and accuracy. In this paper, we extract three fea...

اواسط شهریور 1401 و در نزدیکی ساحل ماسه‌ای رودخانۀ نکا شمال ایران، به روش تورزدن روی گل‌آذین بوته‌های کاهوک (.Lactuca serriola L) میان تمشک وحشی (.Rubus idaeus انار (.Punica granatum L)، نمونه‌ای جیرجیرک جمع‌آوری شد که بررسی توسط کلیدهای شناسایی شکل‌شناسی مقایسه با نمونه‌های از قبل تعیین نام شدۀ موزۀ حشرات هایک میرزایانس رکورد جدید جنس گونه را تایید کرد. این اولین گزارش گونۀ Arachnocephalus ves...

در صنعت پالایشگاه و پتروشیمی‌ها به دلیل وجود تجهیزات تمام فلزی محیط اسیدی خوردگیتنشی زیاد است با توجه افزایش کاربرد فولادهای زنگ نزن این صنایع پژوهش بررسی اثر ضربات امواج اولتراسونیک بر رفتار خوردگی فولاد 316 (S.S 316) می‌پردازیم. هدف از تأثیر روش تنش‌زدایی برافزایش مقاومت قطعات محیط‌های خورنده است. لازم ذکر که، تنش پسمان نمونه‌ها جوش‌کاری ایجادشده ابتدا نمونه مدنظر استفاده ارتعاش تحت فرکانس 20...
