the hallmarks of leukocyte adhesion deficiency (lad) are defects in the leukocyte adhesion process, marked leukocytosis and recurrent infections. these molecular and clinical manifestations result from an impaired step in the inflammatory process, namely, the emigration of leukocytes from the blood vessels to sites of infection, which requires adhesion of leukocytes to the endothelium. over las...

The Auger process on shallow levels, caused by the Auger process in deeper levels, called "cascade Auger process", were studied. From the measurement result, the cascade Auger process can be clearly observed by the excitation of X-ray tubes instead of a synchrotron radiation source. Applying a theoretical investigation with a cluster calculation to the spectral change of the Ag M(VI,V)VV peak, ...

Cascaded cryptographic keystream generators as proposed by Gollmann possess a cryptanalytic weakness termed "lock-in'' in this article. If the initial state has been guessed correctly apart from its phase a decryption cascade can be set up in which the effects of each stage of the original cascade are unravelled in reverse order. Once the decryption cascade has "locked in" on the original casca...

In this paper, a novel problem of observer-based adaptive fuzzy fractional control for fractional order dynamic systems with commensurate orders is investigated; the control scheme is constructed by using the backstepping and adaptive technique. Dynamic surface control method is used to avoid the problem of “explosion of complexity” which is caused by backstepping design process. Fuzzy logic sy...

Mechanically refrigerated test chambers are classified as either single stage low (-40 °C) or cascade ultralow (-70 °C) temperature systems. While cascade systems are reliable and versatile, the potential for leakage between stages within a cascade heat exchanger remains. Further, the need for two compressors and increased control mechanisms can make the system more and more complex. The only m...

A novel cascade electro-osmotic pump (EOP) has been fabricated by alternately connecting a cation monolithic column and anion monolithic column in series. In this manner, the change of electric polarity between each stage of the cascade EOP is easily achieved and the pressure output of the EOP could be greatly enhanced without increase of the applied voltage.

Traumatic brain injury (TBI) determinate a cascade of events that rapidly lead to neuron's damage and death. We already reported that administration of FeTPPS, a 5,10,15,20-tetrakis (4-sulfonatophenyl) porphyrin iron III chloride peroxynitrite decomposition catalyst, possessed evident neuroprotective effects in a experimental model of spinal cord damage. The present study evaluated the neuropro...
