For future 20+ T accelerator type magnets, Re BCO superconductors are ideal for their high current density in magnetic field. At CERN, demonstrator dipole magnets using conductor being developed order to study feasibility. In this work, a design of cloverleaf-racetrack magnet is presented, whic...

In this work we directly evaluate five candidate programming models for future exascale applications (MPI, MPI+OpenMP, MPI+OpenACC, MPI+CUDA and CAF) using a recently developed Lagrangian-Eulerian explicit hydrodynamics mini-application. The aim of this work is to better inform the exacsale planning at large HPC centres such as AWE. Such organisations invest significant resources maintaining an...

We report the identification of novel tRNA species with 12-base pair amino-acid acceptor branches composed of longer acceptor stem and shorter T-stem. While canonical tRNAs have a 7/5 configuration of the branch, the novel tRNAs have either 8/4 or 9/3 structure. They were found during the search for selenocysteine tRNAs in terabytes of genome, metagenome and metatranscriptome sequences. Certain...

introduction: skull-based osteomyelitis is bony infection which generally originates from inadequately treated chronic infection, adjoining tissue infection or after trauma.case: 11 month female child had a trivial fall while standing near a bucket. the child developed fracture of right clavicle and left orbital swelling which was inadequately treated. this resulted in in spread of infection to...

localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. despite development of many techniques including angiography, mri, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). a step forward to achieve this goal is to develop a navigation system. in this manuscript, we explained so...

We investigate theoretically the collective excitations of trapped Bose condensates with energies of the order of the chemical potential of the system. For the MIT sodium Bose condensate in a Cloverleaf trap, we find interesting level crossing behavior for high energy excitations and calculate the spatial magnetic dipole moments for selective creation of condensate excitations.

skull metastasis from hepatocellular carcinoma, specially as the first presentation is very rare. we report a case with a history of head trauma in bam earthquake and craniotomy due to lytic tumor of the skull, presented with upper gastrointestinal symptoms which hepatocellular carcinoma with skull metastasis was revealed .the patient was infected with hepatitis b virus without cirrhosis.
