The effect of dopant concentration on the blue upconversion (UPC) emission of Tm(3+) -doped ZrO(2) nanocrystals under different excitation wavelengths in the red region is reported. The UPC emissions are due to the f-f electronic transitions from excited states (1)G(4) and (1)D(2) of Tm(3+). We observed a chromatic change in the UPC with tuning the excitation wavelength. The UPC emission bands ...
Discrete Differential Geometry is a broad new area where differential geometry (studying smooth curves, surfaces and other manifolds) interacts with discrete geometry (studying polyhedral manifolds), using tools and ideas from all parts of mathematics. This report documents the 29 lectures at the first Oberwolfach workshop in this subject, with topics ranging from discrete integrable systems, p...
کادر(قاب) یکی از عناصر تشکیلدهندهی اکثر نگارههای کتب مصور است که اغلب به صورت چهارضلعی بدون شکست و در مواردی نیز به اشکال گوناگون و چند ضلعیهایی فراتر از چهار ضلع، با شکاف و شکستگی ترسیم شدهاست. اشکال مختلف کادر و ترسیم بخشی از نگاره خارج از مرزهای کادر، در نگارههای پیش از ایلخانی و بهطور گسترده در نگارههای دورهی ایلخانی و تیموری مشاهده شدهاست. در این پژوهش سعی شده نگارههای مکاتب تبر...
Abstract Linguistic expressions in social media vary along many axes, including author style, the specific medium and its affordances, others. In this paper, we argue that different registers must be distinguished within register should included as an important factor independent of (social) analyses variable linguistic phenomena. We introduce a new German cross-media corpus, consisting blog po...
The spectroscopic characteristics (absorption, emission, and fluorescence lifetime) of 13 commercially available red-absorbing fluorescent dyes were studied under a variety of conditions. The dyes included in this study are Alexa647, ATTO655, ATTO680, Bodipy630/650, Cy5, Cy5.5, DiD, DY-630, DY-635, DY-640, DY-650, DY-655, and EVOblue30. The thorough characterization of this class of dyes will f...
AIM To investigate both whether the risk of gastric cancer is associated with the Ile/Val single nucleotide polymorphism (SNP) of human epidermal growth factor receptor-2 (HER-2) transmembrane domain-coding region at codon 655 and the suggested existence of HER-2 expression in gastric cancer cases in a Turkish patient group. METHODS Polymerase chain reaction (PCR) followed by restriction frag...
The use of nicotinic acid to treat dyslipidemia is limited by induction of a "flushing" response, mediated in part by the interaction of prostaglandin D(2) (PGD(2)) with its G-protein coupled receptor, DP1 (Ptgdr). The impact of DP1 blockade (genetic or pharmacologic) was assessed in experimental murine models of atherosclerosis. In Ptgdr(-/-)ApoE(-/-) mice versus ApoE(-/-) mice, both fed a hig...
netically controlled mechanism by which multicellular organisms to regulate normal cell development, tissue homeostasis, and immunological responses. During apoptosis, various cellular events occur, including morphological changes, exposure of phosphatidylserine (PS) on the cell surface, and fragmentation of nuclei. Molecules on the surfaces of apoptotic cells are recognized by macrophages and ...
Astrovirus contains three open reading frames (ORF) on its genomic RNA, ORF1a, ORF1b, and ORF2. ORF1a encodes a 920-amino-acid (aa) nonstructural protein, nsP1a, which displays a 3C-like serine protease motif. Little is known about the processing of nsP1a or whether the protease it contains is active and involved in autocatalytic processing. Here we address both of these matters. Intact and N-t...
