We introduce a new class of event shapes to characterize the jet-like structure of an event. Like traditional event shapes, our observables are infrared/collinear safe and involve a sum over all hadrons in an event, but like a jet clustering algorithm, they incorporate a jet radius parameter and a transverse momentum cut. Three of the ubiquitous jet-based observables — jet multiplicity, summed ...

To the Editor-The case report by Baraka’ of jet ventilation through an airway exchange catheter (Cook Critical Care, Bloomington, IL) complicated by tension pneumothorax and cardiac asystole highlights some of the serious dangers of jet ventilation. I would like to focus on three aspects of the case report. The lessons from these can be added to the recommendations made by Baraka at the end of ...

This contribution summarizes the use of plasmon surface polaritons and guided optical waves for the characterization of interfaces and thin organic films. After a short introduction to the theoretical background of evanescent wave optics, examples are given that show how this interfacial "light" can be employed to monitor thin coatings at a solid/air or solid/liquid interface. Examples are give...

The technique of wavelength scanning digital holographic microscopy (WSDHM) is improved by use of a digital spectral shaping method which is used to suppress the sidelobes of the amplitude modulation function in WSDHM for non-Gaussian-shaped source spectra. Spurious structures caused by sidelobes can be eliminated in tomographic imaging and the performance of the tomographic system greatly impr...

Tissues throughout the body exhibit circadian rhythms, forming a multioscillatory system whose disruption results in jet lag and other health problems in travelers and rotational shift workers. The authors' simulations of the dynamics of a multistage circadian system (based on experimental results for nocturnal rodents) reveal the flexibility and stability inherent in a multistage system, as we...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...
