at higher layers in our architecture. This means that a monitoring module is replicated at the lowest layer, but controlled at the synthesizing module level. If, for example, one replica of a monitoring module fails, the controlling function in the layer above might still obtain results from the other two replicas when a time-out occurs (Hartvigsen and Johansen, 1990a). A third motivation in ou...
Vector autoregressive (VAR) models have often been used in the econometric literature as useful models to describe stationary/non-stationary time series. Additionally cointegrating vectors are of primary interest for researchers who investigate the long-run stable relationship between economic variables. In VAR models it is well known that cointegrating vectors are identifiable only up to their...
the aim of this research is to analyse of empirical relationship of fiscal policy and iranian trade account in the years 1338-1385(1959-2006). in and econometrics model the methods of engle and granger (1987), johansen (1988), ardl, pessaran and shin(1998), philips and hansen(1990), have been used to find out the effects of variables such as government expenditures(the component of public deman...
1. YKL-40 In a search of new bone proteins, the glycoprotein YKL-40 was identified in 1989 to be secreted in vitro in large amount by the human osteosarcoma cell line MG63. The protein was named YKL-40 based on its three N-terminal aminoacids Tyrosine (Y), Lysine (K) and Leucine (L) and its molecular mass of 40 kDa (Johansen et al. 1992). This protein was later found to be similar to a protein ...
Currently, no approved therapeutics exist to treat or prevent infections induced by Ebola viruses, and recent events have demonstrated an urgent need for rapid discovery of new treatments. Repurposing approved drugs for emerging infections remains a critical resource for potential antiviral therapies. We tested ~2600 approved drugs and molecular probes in an in vitro infection assay using the t...
In a series of papers based on analogies with statistical physics models, we have proposed that most financial crashes are the climax of so-called log-periodic power law signatures (LPPS) associated with speculative bubbles [Sornette and Johansen, 1998, Johansen and Sornette, 1999, Johansen et al., 1999, Johansen et al., 1999, Sornette and Johansen, 2001]. In addition, a large body of empirical...
