Deploying Grid technologies by distributing an application over several machines is widely emerging for scientific simulations, which have large requirements for computational resources. While in the last couple of years distributed simulations were often executed on a pure demonstration level, currently ongoing work is focusing on taking the steps necessary to use the technology in an every da...

The effects of glia conditioned media on the survival and differentiation of embryonic neuron cultures of the Central Nervous System is described. We established glial cultures of peritumoral areas and the culture medium was changed serially and collected as glia conditioned medium (GCM). Neuron enriched cultures plated on poly-L-lysine coated Petri dishes and after 4 days in vitro, the neurona...

Neurons and glia are generated from multipotent neural progenitors. In Drosophila, the transcriptional regulation of glial vs. neuronal fates is controlled by the expression of the transcription factor encoded by the glial cells missing gene (gcm) in multiple neural lineages. The cis-regulatory control of gcm transcription serves as a nodal point to translate a complex array of spatially and te...

We are presenting an implementation of the Galois/Counter Mode (GCM) for the Advanced Encryption Standard (AES) in IPsec in this paper. GCM is a so called “authenticated encryption” as it can ensure confidentiality, integrity and authentication. It uses the Counter Mode for encryption, therefore counters are encrypted for an exclusiveOR with the plaintext. We describe a technique where these en...

As the surface drag is increased in a comprehensive general circulation model (GCM), the upper-level zonal winds decrease and eddy momentum flux convergence into the jet core increases. Globally averaged eddy kinetic energy decreases, a response that is inconsistent with the conventional barotropic governor mechanism whereby decreased barotropic shears encourage baroclinic wave growth. As the c...

The recently introduced Galois/Counter Mode (GCM) of operation for block ciphers provides both encryption and message authentication, using universal hashing based on multiplication in a binary finite field. We analyze its security and performance, and show that it is the most efficient mode of operation for high speed packet networks, by using a realistic model of a network crypto module and e...

A short review of analytical and numerical results, obtained for collective dynamics in liquid metals and alloys within a theoretical approach of Generalized Collective Modes (GCM) is presented. The GCM approach permits to represent dynamic structure factors in wide ranges of wave numbers and frequencies as a sum of contributions from hydrodynamic and non-hydrodynamic processes. The origin of c...

Methods A retrospective cohort study at two Canadian centres was performed. The longitudinal trajectories of AJC were described using latent growth curve modeling (GCM). Latent GCM is a novel technique that aims to classify individuals into statistically distinct groups based on individual response patterns so that individuals within a group are more similar than individuals between groups. The...

Radiative heating associated with the distribution of water vapor and clouds in the atmosphere is an important driver of both local-scale and large-scale circulations in the tropics. One of the difficulties in producing accurate cloud and radiative heating rate profiles with a general circulation model (GCM) is the sub-grid scale nature of cloud processes and their interaction with radiation. T...
