Each acoustic instrument is one of a kind. Its unique acoustic properties are transferred from the physical characteristics of its source materials and a handcrafted touch. In contrast, electronic and computer-based instruments lack this distinguishing trait. Though the technology support in music instruments offers great flexibility, it tends to foster predictable and generic results, particul...

Eradicating cancer cells: struggle with a chameleon

Eradication of cancer stem cells to abrogate tumor growth is a new treatment modality. However, like normal cells cancer cells show plasticity. Differentiated tumor stem cells can acquire stem cell properties when they gain access to the stem cell niche. This indicates that eradicating of stem cells (emptying of the niche) alone will not lead to eradication of the tumor. Treatment should be dir...

Defining line replaceable units

Defective capital assets may be quickly restored to their operational condition by replacing the item that has failed. The item that is replaced is called the Line Replaceable Unit (LRU), and the so-called LRU definition problem is the problem of deciding on which item to replace upon each type of failure: when a replacement action is required in the field, service engineers can either replace ...

Replaceable Implementations for Actor Systems

CoDE is an actor-based software framework aimed at both simplifying the development of large and distributed complex systems and guarantying an efficient execution of applications. This software framework takes advantage of a concise actor model that makes easy the development of the actor code by delegating the management of events (i.e., the reception of messages) to the execution environment...
