Premovement activities in neurons in the intermediate gray layer [stratum griseum intermediale (SGI)] of the mammalian superior colliculus (SC) are essential for initiation of orienting behaviors such as saccades. Our previous study demonstrated that burst activities are induced by synchronous activation of SGI neurons communicating within a local excitatory network, which depends on NMDA-recep...

I evaluated the performance of the SGI Altix 4700 by using several well-known benchmarks. In performing these experiments we hope to gain a better understanding of the capabilities and limitations of the system, and thus be able improve upon the design in future generations or develop tools that enhance the performance of the system.

The purpose of this paper is whom do Sports Goods Industry (SGI) consider as their stakeholder, which stakeholders they give priority to others and why. present study exploratory. A list sports goods manufacturers in Meerut was procured from the Federation manufacturers. total number per 356. With help a simple random sampling technique, 50 were selected for pilot study, 100 final study. requir...

Purpose Vogt-Koyanagi-Harada (VKH) disease is a systemic autoimmune disorder that affects organs with melanocytes. The sunset glow fundus (SGF) in VKH disease was evaluated with polarization-sensitive optical coherence tomography (PS-OCT). Methods The study involved 28 eyes from 14 patients with chronic VKH disease, 21 eyes from 21 age-matched controls, and 22 eyes from 22 high-myopic patient...

In this work the well known wavelet/subband decomposition algorithm (3-D case) widely used in picture and video coding is parallelized using PVM and MPI as well as with data parallel language extensions. The approaches try to take advantage of the possibilities the respective programming interfaces ooer. Experimental results are conducted on an SGI POWERChallenge GR and an SGI Origin 2000. Thes...

Ringed structures have been observed in a variety of protoplanetary discs. Among the processes that might be able to generate such features, Secular Gravitational Instability (SGI) is possible candidate. It has also proposed SGI lead formation planetesimals during non-linear phase instability. In this context, we employ two-fluid hydrodynamical simulations with self-gravity study non-axisymmetr...

The Guild concept has been of great interest to ecologists, and widely applied in entomology, particularly study the activity insects various ecosystems. However, guild storage entomology is understudied. We hypothesized that feeding structure stored grain insect (SGI) community changes with different food resources available. In present study, we examined tribal system. Further, established a ...

The SGI Altix system architecture allows to support very large ccNUMA shared memory systems. Nevertheless, the system layout sets boundaries to the sustained memory performance which can only be avoided by selecting the “right” data access strategies. The paper presents the results of cache and memory performance studies on SGI Altix 350. It demonstrates limitations and benefits of the system a...

Geometric imperfection, known as a detrimental effect on the buckling load of cylindrical shells, has a new role under the emerging trend of using buckling for smart purposes. Eigenshape-based geometries were designed on the shell surface with the aim of tailoring the postbuckling response. Fourteen seeded geometric imperfection (SGI) cylinders were fabricated using polymer-based 3D printing, a...

In this paper, we present an in-depth analysis of the memory system performance of the DSS commercial workloads on two state-of-the-art multiprocessors: the SGI Origin 2000 and the HP V-Class. Our results show that a single query process takes almost the same amount of cycles in both machines. However, when multiple query processes run simultaneously on the system, the execution time tends to i...
