Colloidal matter exhibits unique collective behaviors beyond what occurs at single-nanoparticle and atomic scales. Treating colloidal particles as building blocks, researchers are exploiting new strategies to rationally organize colloidal particles into complex structures for new functions and devices. Despite tremendous progress in directed assembly and self-assembly, a truly versatile assembl...
BACKGROUND Coronary artery spasm (CAS) is known to be a risk factor of acute coronary syndrome and angina pectoris. However, there is no currently available data with larger study population regarding long-term clinical outcomes of CAS in real world clinical practice. OBJECTIVES We evaluated the prevalence of CAS and the impact of CAS on 5-year clinical outcomes in a series of Asian CAS patie...
Recently it has been shown that string gas cosmology, an alternative model of the very early universe which does not involve a period of cosmological inflation, can give rise to an almost scale invariant spectrum of metric perturbations. Here we calculate the non-Gaussianities of the spectrum of cosmological fluctuations in string gas cosmology, and find that these non-Gaussianities depend line...
In this report, I use CAS-PEAL dataset [1] to try and generate facial expressions. That is, I take in, say, a smiling face, and try to generate a face that is neutral. I build off Ghodrati’s, et al. [2] to see if I generate facial expressions. Finally, I use a variant of Deep Convolutional Adversarial Networks, hereafer DCGAN’s, [7] to generate a facial expressions.
BACKGROUND Clinical trials demonstrated the efficacy of carotid artery stenting (CAS) relative to carotid endarterectomy when performed by physicians with demonstrated proficiency. It is unclear how CAS performance may be influenced by the diversity in CAS and non-CAS provider volumes in routine clinical practice. METHODS AND RESULTS We linked Medicare claims to the Centers for Medicare and M...
مقدمه: سودوموناس‌های فلورسنت سیدروفورهای متعددی را تولید می‌کنند که مهم‌ترین آنها سیدروفور نوع پایووردین است. تولید سیدروفور در این باکتری‌ها باعث افزایش فراهمی آهن موردنیاز باکتری و گیاهان می‌شود و همچنین اهمیت ویژه‌ای در کنترل بیماری‌های گیاهی دارد. مواد و روشها: به‌منظور مقایسۀ روش‌های اندازه‌گیری تولید سیدروفور، میزان تولید سیدروفور 21 سویۀ سودوموناس بومی ایران به‌همراه دو سویۀ مرجع خارجی...
Preparation and characterization of friendly colloidal Hydroxyapatite based on natural Milk’s casein
Biocompatible hydroxyapatite nanocomposites are biocompatible, biodegradable and nontoxic have been paid many attentions as one of the most suitable vehicle for drug delivery use. Our objective in this work was to prepare and characterize caseins based HA nanocomposite in a colloidal form for drug delivery purposes. Casein biopolymer was firstly extracted from skimmed milk by adding acetic acid...
With attention to the thin film structure of colloidal quantum dot solar cells, in this paper in order to improvement of active layer absorption of them, we have proposed the use of nanostructure pattern for enhancement of their performance. For this purpose we have presented suitable nano hemisphare patterns in colloidal quantum dot solar cells for light trapping in absorption layer. Then with...
Recognizing the significance of the life stage of fish for nano-eco-toxicological studies, the acute toxicity of colloidal silver nanoparticles (AgNPs) was tested in three different life stages of rainbow trout. Fishes were exposed to colloidal AgNPs at nominal concentrations of 100, 32, 10, 3.2, 1, 0.32, 0.1, and 0.032 mg/L. The estimated 96 hr LC50 values were 0.25, 0.71, and 2.16 mg/L for th...
