We consider approximate Bayesian model choice for model selection problems that involve models whose Fisher-information matrices may fail to be invertible along other competing submodels. Such singular models do not obey the regularity conditions underlying the derivation of Schwarz’s Bayesian information criterion (BIC) and the penalty structure in BIC generally does not reflect the frequentis...

فرزند‌پروری پس از طلاق یکی تکالیف حساس پیش روی والدین مُطلقه، و عوامل مؤثر در سلامت روانی فرزندان به شمار می‌آید. هدف این مطالعه کشف تبیین تجارب زیسته‌ هم‌والدگری است. روش کیفی با استفاده پدیدارشناسی توصیفی انجام شد. جامعه پژوهش شامل کلیه‌ والدینی بود که تجربه‌ فرزندپروری را داشته‌اند. برای تعیین حجم نمونه معیار اشباع داده شد نمونه‌گیری هدفمند تعداد 12 نفر (زن، مرد) انتخاب شدند مورد مصاحبه‌ نیمه...

Abstract Hot electrons generated in metallic nanostructures have shown promising perspectives for photodetection. This has prompted efforts to enhance the absorption of photons by metals. However, most strategies require fine-tuning geometric parameters achieve perfect absorption, accompanied demanding fabrications. Here, we theoretically propose a Ag grating/TiO 2 cladding hybrid structure hot...

background: the two most frequently diagnosed cancers among women worldwide are breast and cervical cancers. the objective of the present study was to classify the different countries based on the death rates from sex specific cancers. methods : in this cross-sectional study, we used dataset regarding death rate from breast, cervical, uterine, and ovarian cancers in 190 countries worldwide repo...

The phenomenon of bound state in the continuum (BIC) with infinite quality factor and lifetime has emerged recent years photonics as a new tool manipulating light-matter interactions. However, most investigated structures only support BIC resonances at very few discrete points w~k space. Even when is switched to quasi-BIC(QBIC) resonance through perturbation, its frequency will still be located...
