Analyses of Bose-Einstein Correlations in WW events at LEP2 by the four LEP collaborations are presented. In particular, Bose-Einstein correlations in WW overlap are investigated and the possible existence of these correlations between particles coming from different W’s, which may influence the W-mass measurements in the fully hadronic channel ee → WW → q1q̄2q3q̄4. No evidence for such an inter-...

We discuss the characteristic interference features of soft radiation in the threshold production of heavy unstable particles: soft gluon radiation in e+e− → tt̄ and soft photon radiation in e+e− → W+W−. We show that the heavy particle decay width controls the interference between the emission off the final state particles. As a result, the radiation pattern may provide a way of measuring the de...

We study the process e+e− → W+W− to probe low-scale gravity at high energy linear colliders. A characteristic signature of extra-dimensions models is the forward-backward asymmetry due to the interference of spin2 graviton and spin-1 SM gauge boson exchange terms, even when rightpolarised electron beam is used. Our analysis shows that larger than 5% asymmetry is possible at a linear collider wi...

We present sensitivity limits on the coefficients of a dimension–6 effective Lagrangian that parametrizes the possible effects of new physics beyond the Standard Model. Our results are based on the study of the process e + e − → W + W − γ at LEP2 and NLC energies. In our calculations, we include all the new anomalous interactions, involving vector and Higgs bosons, and take into account the Sta...

The main purpose of this project is investigation of the organophosphorus hydrolase (OPH) enzyme activity in water in oil (w/o) and oil in water (o/w) creams and investigation of the OPH enzyme stability in formulated creams. OPH enzyme was extracted and purified from strain flavobacterium. The w/o and o/w creams were prepared using different formulations. In order to achieve an emulsion with m...

encapsulation of olive oil is an effective method to protect it against environmental deteriorative factors. in this research, olive oil microcapsules were produced by complex coacervation method. the objective was to examine the effect of gelatin and arabic gum as shell materials, lactose as cryprotectant, and different acidification times on microencapsulation efficiency of olive oil. arabic ...

A modiication to neural network training algorithms is proposed which decorrelates certain weights within the network while minimising the mean squared error. The technique was developed to facilitate neural network interpretation in image processing problems, partly by allowing to initialise all network weights with one xed, low value. However, it can also be applied to classiica-tion tasks in...
