Stereoselective synthesis of alpha-monofluorinated phosphonate mimetics of naturally occurring phosphoserine and phosphothreonine, via electrophilic fluorination of lithiated bis-lactim ethers
(The Royal Society of Chemistry, 2002-06-25)
[Abstract] Electrophilic fluorinations of lithiated bis-lactim ethers derived from cyclo-[L-AP4-D-Val] allow a direct access to alpha-monofluorinated phosphonate mimetics of naturally occurring phosphoserine and phosphothreonine, ...
Near-Field Quasi-Null Control with Far-Field Sidelobe Level Maintenance in Line Source Distributions
(The Institution of Engineering and Technology, 2002-06-06)
[Abstract] An improving method, based on the Taylor line source, that allocates a quasi-null in a specified angular position of near-field pattern, and simultaneously controls the general topography of the far-field sidelobe ...
The lemniscal–cuneate recurrent excitation is suppressed by strychnine and enhanced by GABAA antagonists in the anaesthetized cat
(Wiley, 2002-11-13)
[Abstract] In the somatosensory system, cuneolemniscal (CL) cells fire high frequency doublets of spikes facilitating the transmission of sensory information to diencephalic target cells. We studied how lemniscal feedback ...

Avoiding Interference in Planar Arrays through the Use of Artificial Neural Networks
(Institute of Electrical and Electronics Engineers, 2002-08)
[Abstract] This article implements an artificial neural network to find, through computer simulation, the excitations of a square planar array. The array is composed of 52 uniformly spaced subarrays, and has a quasi- in ...
Redescription of "Sigambra tentaculata" and re-establishment of "S. parva" (Polychaeta, Pilargidae) based upon type material
(Station Biologique de Roscoff, 2002)
[Abstract] The pilargid polychaetes Sigambra tentaculata and S. parva, to date considered synonyms, are redescribed from
the examination of type material and additional specimens from the East coast of the U.S.A., and the ...
Exploiting locality in the run-time parallelization of irregular loops
(C R C Press, LLC, 2002-12-10)
[Abstract] The goal of this work is the efficient parallel execution of loops with indirect array accesses, in order to be embedded in a parallelizing compiler framework. In this kind of loop pattern, dependences can not ...

(Springer, 2002)
Soil biofilters and related systems based onthe use of natural filter beds have been usedfor several years for solving specific airpollution problems. Over the past decade,significant improvements have been brought tothese ...
Numerical approaches for grounding installations in uniform and stratified soils
(2002)
[Abstract] This paper summarizes the main numerical approaches based on the BEM developed by the authors in the last years for the grounding analysis of electrical installations in uniform and layered soils.
