Modern high speed interconnects such as Myrinet and Gigabit Ethernet have shifted the bottleneck in communication from the interconnect to the messaging software at the sending and receiving ends. The development of userlevel protocols and their implementations on smart and programmable network interface cards (NICs) have been alleviating this communication bottleneck. Most of the userlevel pro...

In the present study it was demonstrated that the NICS(zz)-scan patterns along with symmetry-based selection rules can unequivocally probe the antiaromaticity in a wide range of antiaromatic organic and inorganic rings/cages. The NICS(zz)-scan profiles typical of antiaromaticity correspond to symmetric curves around the axis perpendicular to the ring plane with the positive NICS(zz)(R) values d...

Scholars and policy makers have long debated the causes of the spectacular economic success achieved by the East Asian newly industrialisin g countries (NICs) as well as the lessons that other developing countries can learn from this development experience. Latin America started to industrialise many decades before the East Asian NICs and yet was quickly overtaken by them in the last few decade...

Part of the University of Campinas (UNICAMP, www.unicamp.br), the Interdisciplinary Nucleus of Sound Communication (NICS, www.nics.unicamp.br) was founded in 1983 by the composer Raul do Valle and collaborators. Since then, NICS has maintainined a longstanding list of participations in the academic and artistic musical scenario, specially the ones concerning the application of mathematical mode...

Aromatic compounds are characterised by the presence of a ring current when in a magnetic field. As a consequence, current density maps are used to assess (the degree of) aromaticity of a compound. However, often a more discrete set of so-called Nucleus Independent Chemical Shift (NICS) values is used that is derived from the current density. It is shown here that there is no simple one-to-one ...

Noninvasive cortical stimulation (NICS) can produce analgesic effects by means of repetitive transcranial magnetic stimulation or transcranial direct current stimulation (tDCS). Such effects have been demonstrated on chronic ongoing pain, as in acute provoked pain. The investigation of induced changes in the perception of experimental pain by NICS could help clinicians and researchers to better...

The nucleus-independent chemical shifts (NICS) and electron density profiles along the inner and outer regions defined by the two stacked aromatic rings of [2.2]paracyclophane have been analyzed and compared to those of free benzene and p-xylene and benzene dimers taken as reference models. It is found that stacked aromatic rings show a reduction of the NICS indicator of aromaticity as compared...

As compared to classical organic aromatic compounds, the evaluation of aromaticity in all-metal and semimetal clusters is much more complex. For a series of these clusters, it is frequently found that different methods used to discuss aromaticity lead to divergent conclusions. For this reason, there is a need to evaluate the reliability of the different descriptors of aromaticity to provide cor...

A series of monocyclic planar inorganic compounds have been optimized at the B3LYP/6-311+G* level. GIAO-B3LYP nucleus-independent chemical shifts (NICS) profiles calculated in the perpendicular direction of each ring show that the series of analyzed compounds can be classified in three groups according to their aromatic, non-aromatic or antiaromatic character. Our results suggest exercising cau...
