The most recently available results from searches conducted by the four LEP experiments at 189 GeV center-of-mass energy for Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) are presented. No evidence for a signal has been observed, and the null result is used by the experiments, both individually and collectively, to exclude regions of the MSSM parameter space and to set lower ...

Higher water potentials in recovering burned salt-cedar (Tamarix ramosissima) relative to unburned plants and the opposite situation in willow (Salix gooddingii) provide evi­ dence that postfire water stress is reduced in the former but not the latter. Similarly, diurnal patterns ofstomatal con­ duc(ance in these taxa are consistent with the existence of more vigor in burned salt-cedar than wil...

This paper presents a response surface analysis for the …nite sample distributions of two popular panel unit root tests developed by Chang (2002) and Chang and Song (2005). Numerical distributions illustrate signi…cant di¤erences between …nite sample and large sample properties. Dependence of …nite sample bias on sample size is investigated. The paper provides 95% con…dence intervals for the cr...

We conduct a proper test of the claim that people are overcon…dent, in the sense that they believe that they are better than others. The results of the experiment we present do not allow us to reject the hypotheses that the data has been generated by perfectly rational, unbiased, and appropriately con…dent agents. Keywords: Overcon…dence; Better than Average; Experimental Economics; Irrationali...

Since the emergence of acquired immune deficiency syndrome (AIDS), tuberculosis and human immune defi­ ciency virus (HIV) infection have been intimately linked. Several studies have clearly shown that the incidence of active tuberculosis is increased in HIV infected patients (1). AIDS patients with tuberculosis have a higher inci­ dence of extra-pulmonary and pleural disease. The most common si...

This paper introduces, for an experimental design with design matrix X; the optimal design criterion based on the expectation of the square root of the quadratic form u(XX)u. This provides a geometric and statistical measure of the size of a con ̄dence ellipsoid, namely, the expected radius of an ellipsoid. Properties of the criterion are derived and examples are given to demonstrate the procedu...

The analysis of foodstuffs, such as rice, is of particular interest for nutrient elements present at high concentrations, and also for toxic elements such as cadmium that can be present at trace levels. The analysis is important to ensure product quality and safety, as well as determining product origin. Food scares related to contamination not only constitute a health risk but also undermine c...

Two cases of acute lymphoblastic leukemia process rather than part of it. A mechanism with eosinophilia are described. The degree for the production of the eosinophilia is of eosinophilia was such that at presentadiscussed, and it is suggested, on the basis tion, a provisional diagnosis of eosinoof our findings, that acute eosinophilic philic leukemia was made. Cytogenetic evileukemia may be of...

In this work, we have applied two geophysical techniques in different areas of potential interest for paleoseismological assessment the active faults Acambay graben. The main goal was to localize segments buried suspected break surface during 1912 Earthquake, order (1) identify favorable sites investigation purpose and (2) extrapolate data obtained with a paleoseismic trenching. On one hand, El...
