BACKGROUND AND AIMS Ambrosia artemisiifolia is a ruderal weed introduced from North America to Europe. It produces large amount of achenes which are highly heterogeneous in size. Due to the preponderant role of propagules in invasive plant processes, the achene mass variability related to germination, dispersal strategy and life history traits of offspring were investigated within this species....

The multiple-input floating gate transistors were used to simplify the design of multiple valued logic. The Quasi-floating gate node have a well defined DC operating point. The multi-input quasi-floating gate is used for low voltage applications because its effective threshold voltage will be controllered to a low value.

In deep submicron CMOS and BICMOS technologies, antenna effects affect floating gate charge of usual floating gate test structures, dedicated to capacitor matching measurement. In this paper a new pseudo-floating gate test structure is designed. After test structure and modeling presentation, testing method and results are given for several capacitor layouts (poly-poly and metal-metal). key wor...

Floating-point numbers and floating-point arithmetic contain some surprising pitfalls. In particular, the widely-adopted IEEE 754 standard contains a number that is “not a number,” and thus has some surprising properties. One has to be extremely careful in writing assertions about floating point numbers, to avoid these pitfalls. This column describes the problems and how a language might elimin...

Floating of bodies heavier than the supporting liquid is discussed. Floating of cylindrical, ellipsoidal bodies and rectangular plates possessing lateral dimensions smaller than the capillary length is treated. It is demonstrated that more elongated bodies of a fixed volume are better supported by capillary forces, due to the increase in the perimeter of the triple line. Thus, floating of metal...

PURPOSE We describe an unusual clinical finding of a free-floating iris cyst in a patient with recurrent iritis. METHOD The clinical finding of a free-floating iris cyst was recorded using slit-lamp photography. RESULTS A 39-year-old male with a 5-year history of recurrent right iritis was found to have a small mobile iris cyst within his right anterior chamber, first identified 3 years ago...
