یکی از پیش فرضهای اولیه مدل مارکوف پنهان، اعمال توزیع آماری هندسی به کشش زمانی بردارهای هر حالت مدل مارکوف پنهان است که به وضوح با طبیعت مساله سازگار نیست. مدلهای قطعه ای اتفاقی و به طور خاص مدل مارکوف پنهان قطعه ای تا حدی این مشکل را به ازای پیچیدگی بیشتر در مراحل آموزش و بازشناسی حل می کند. در مقابل، مدلهای شبکه عصبی و مدل ادراک گفتار دانشگاه ام آی تی از این مدلسازی چشم پوشی کرده اند. در این ...

An examination of the carotene fractions extracted from Euglena gracilis Z and pressure-bleached Euglena mutants PR-1, PR-2, PR-3, and PR-4 revealed phytoene in mutants PR-1, PR-2, and PR-3. Photosynthetic E. gracilis Z cultured at different light intensities showed no detectable phytoene, nor was phytoene found in mutant PR-4. However, dark-cultured E. gracilis Z yielded readily assayable amou...
The increasing use of participatory research (PR) approaches to address pressing public health issues reflects PR's potential for bridging gaps between research and practice, addressing social and environmental justice and enabling people to gain control over determinants of their health. Our critical review of the PR literature culminates in the development of an integrative practice framework...
در این کار یک کمپلکس جدید [co(bae)(pme2ph]+ سنتز و شناسایی شده است. برای این کمپلکس و کمپلکس [co(bae)(pbu3)]+ ثابت تعادل و پارامترهای ترمودینامیکی از طریق طیف سنجی اندازه گیری شده است. این کمپلکس ها را به عنوان الکترون با فسفیتهای p(ome)3 , p(oet)3 , p(oi-pr)3 به عنوان دهنده الکترون در تشکیل ترکیب اضافی 1:1 در حلالهای استونیتریل و )dma با قدرت یونی ثابت و در دماهای مختلف واکن...
This note describes some additional information that complements the main BayesAct-S model described in [2] 1 Comparing Situational and Fundamental Self Sentiments In the paper we use the following function to measure inauthenticity: ia(s) = ln ( Pr(ss) Pr(sf ) ) (1) However, the original statement of the theory in [1] hypothesises that inauthenticity is a difference, from which we derived that...
Background: Papillary thyroid carcinoma (PTC), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. The objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in PTC with regard to age, gender, tumor size and lymph node involvement. Methods: Immunohistochemical stains were performed on 92 tissue bl...
BACKGROUND Pulmonary rehabilitation (PR) is an effective intervention for COPD. However, traditional center-based PR programs suffer from low uptake. Home-based PR is a viable solution, but few studies have shown the effectiveness of remote PR, as there is a scarcity of systems that can be easily adopted in clinical practice. The aim of this report is to communicate the development and feasibil...
BACKGROUND Bronchiectasis is a chronic suppurative lung disease often characterised by airflow obstruction and hyperinflation, and leading to decreased exercise tolerance and reduced health status. The role of pulmonary rehabilitation (PR) and inspiratory muscle training (IMT) has not been investigated in this group of patients. METHODS Thirty two patients with idiopathic bronchiectasis were ...
Progesterone receptor isoforms, agonists and antagonists differentially reprogram estrogen signaling
Major roadblocks to developing effective progesterone receptor (PR)-targeted therapies in breast cancer include the lack of highly-specific PR modulators, a poor understanding of the pro- or anti-tumorigenic networks for PR isoforms and ligands, and an incomplete understanding of the cross talk between PR and estrogen receptor (ER) signaling. Through genomic analyses of xenografts treated with ...
