The LEP results for the eeective mixing angle sin 2 lept ef f from measurements of the inclusive charge ow in hadronic Z decays are presented. Using the very precise LEP data on exclusive and inclusive particle spectra to constrain the predictions of hadronization models systematic uncertainties have been reduced. The combined LEP result is sin 2 lept ef f = 0:2320 0:0010.

Several studies have shown the important actions of cytokine leptin that regulates food intake and energy expenditure. Additionally, the ability to modulate hematopoiesis has also been demonstrated. Previous reports have shown that some synthetic sequences of leptin molecules can activate leptin receptor. Herein, decapeptides encompassing amino acids from positions 98 to 122 of the leptin molec...

In 1993 LEP performed a scan at three energy points around the Z 0 mass, with the primary aim of substantially improving the errors on M Z and ? z. The results of the preliminary lineshape analyses of the 4 LEP experiments are presented here, together with the combined LEP averages. The Z 0 mass and width are determined as M Z = 91:1899 0:0017 exp 0:004 lep Gev and ? z = 2:4971 0:0027 exp 0:002...

Painful stimuli delivered by infrared laser stimulators elicit laser-evoked potentials (LEP) or magnetic fields in respective electroencephalogram (EEG) and magnetoencephalogram (MEG). Evidence is reviewed that LEP represent a series of event-related potentials (ERP) that depend on vigilance and arousal, selective spatial attention and contextual task variables. Paradigms adopted from other sti...

LEP results have constrained heavily the Minimal Supersymmetric Standard Model, while providing hints for light Higgs boson and for “SUSY-assisted” gauge couling unification. In this paper the results obtained at LEP within two scenarios, the gravity-mediated MSSM framework and the minimal SUGRA scenario are presented. Model-dependence and coverage of LEP results is discussed. Preprint USIP-2/2002

The lepidopteran family Lymantriidae contains about 200 genera and about 2,500 described species, mostly from the Old World Tropics (DeWorms, 1983). Of the 46 recognized species and subspecies of Lymantriidae in North America, 30% are considered pests (Ferguson, 1978). The pest species include three introduced species which have become established in North America, the gypsy moth, Lymantria dis...

The number, morphometric parameters and amount of aminergic neurosecretory product of protocerebral A2 neurosecretory neurons were investigated in the fifth instar of Lymantria dispar caterpillars, following a suitable or unsuitable trophic regime. Caterpillars originated from two populations (Quercus rubra or Robinia pseudoacacia forest) and were differently adapted to trophic stress, i.e. fee...
