this study was performed in order to evaluate the effects of drought stress and nitrogen fertilizer on phenology, morphology and yield of four cultivars of chickpea. this experiment was performed in a split-factorial using randomized complete block design with three replications. drought stress treatment stood in main plots (in three levels) consisting of no drought stress (control), moderate d...

The present study investigates the trend of linguistic borrowing in Classical and Modern Arabic two texts: Prophet’s Biography by Ibn Hisham (Classical) novels Hashem Gharaibeh (Modern). It aims to highlight capabilities adapt with other languages find out pattern morpho- phonological adaptation that applies borrowings. In addition, at figuring whether semantic classification these borrowings i...

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...

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...

OBJECTIVE To discuss and compare the results of suturing the nasal septum after septoplasty with the results of nasal packing. METHODS A prospective study, which was performed at Prince Hashem Military Hospital in Zarqa, Jordan and Prince Rashed Military Hospital in Irbid, Jordan between September 2005 and August 2006 included 169 consecutive patients that underwent septoplasty. The patients ...

| Neural networks based model-ing often involves trying multiple networks with diierent architectures and/or training parameters in order to achieve acceptable model accuracy. Typically, one of the trained NNs is chosen as best, while the rest are discarded. Hashem and Schmeiser 1] propose using optimal linear combinations of a number of trained neural networks instead of using a single best ne...

This paper examines whether endogenous growth processes can be found in middle income country contexts. Estimation proceeds by means of dynamic heterogeneous panel analysis. Empirical evidence ...nds in favour of both knowledge spill-over e¤ects, and of positive impacts on total factor productivty growth by Schumpeterian innovative activity. A crucial ...nding is that spill-over e¤ects emerge f...

Proof. The result follows by direct manipulation of the terms. Lemma S2 Suppose that the k×k matrices A and B have bounded spectral norms ‖A‖ ≤ λ and ‖B‖ ≤ λ, for some fixed positive constant λ. Then ∥∥∥Ah −Bh∥∥∥ ≤ hλh−1 ‖A−B‖ , for h = 1, 2, .... (A.1) Proof. We establish this result by backward induction. It is clear that it holds for h = 1. For h = 2, using the identity A −B = A(A−B) + (A−B)...
