This papers considers how trading activity at one maturity of the yield curve a¤ects and is a¤ected by trading at other maturities. We approach the modeling of bond prices from a stochastic volatility and market microstructure perspective based on time deformation. We …nd that individual yields are driven by di¤erent ‘market clocks’suggesting di¤erent price discovery processes at di¤erent yield...

Infertility has long been a difficult issue for many couples. The successful differentiation of germ cells and live progeny from pluripotent stem cells brings new hope to the couples suffering with infertility. Here we successfully isolated human fetus skin-derived stem cells (hfSDSCs) from fetus skin tissue and demonstrated that hfSDSCs can be differentiated into early human germ cell-like cel...

in order to study the effects of planting date and plant density on yield and its components in three chickpea (cicer arietinum l.) cultivars in rainfed conditions of ilam, a field experiment was carried out using split plot design as factorial by complete randomized block design with three replications at shirvan-chardavol agriculture research station during 2008-2009. sowing dates were assign...

BACKGROUND Several contraindications for intravenous thrombolysis are not based on controlled trials. Specialized stroke centers often apply less restrictive criteria. The aim of our study was to analyze how many patients at our institution receive off-label thrombolysis. In addition, clinical outcome and safety data were compared to those from patients treated on-label, and the influence of di...

String matching is one of most challenging issues in computer science. In this study, a new efficient hybrid string matching algorithm called Atheer was developed. This proposed algorithm is integrated with the excellent properties of three algorithms, namely, the Karp–Rabin, Raita, and Smith algorithms. The Atheer algorithm demonstrated an efficient performance in the number of comparison atte...

We develop a theoretical framework for understanding how agents form expectations about economic variables with a partially predictable component. Our model incorporates the e¤ect of measurement errors and heterogeneity in individual forecasters’prior beliefs and their information signals and also accounts for agents’learning in real time about past, current and future values of economic variab...
