Compositions and methods for monitoring the quantity of actinides present in a test sample are disclosed. The thermoplastic material is a composite material including polypropylene copolymer, glass fiber, UV stabilizers, filler such as talc and pigment. A master clock generator generates a master clock for distribution to the clock processor nodes, via the clock distribution network, to compensate clock skew and filter clock jitter locally at the respective local clock regions. The technique is particularly effective for use in identifying optimal epicardial pacing locations for mounting satellite pacing devices for use in delivering cardiac resynchronization therapy. The created music piece is a new piece but resembles the source music piece to a certain extent having certain characteristic features of the source music. A user can click and drag a cursor on the model to deform the model to align with the clinical image.
