The basic functions of a typical satellite, distilled to their quintessence, include only the absorption, processing, and subsequent re-radiation of photons. To this end, spacecraft components need only be able to exchange energy – which tends to be dichotomized into power and information – and transmit the occasional force or torque. Perfectly adequate and efficient mechanisms for accomplishin...

In view of non-specific toxicity of most chemotherapeutic agents against normal cells, the development of targeted chemotherapy is warranted. Efficient targeting of chemotherapeutic drugs to the cancerous area could be of great benefit for patients with advanced or metastatic tumors. Targeted cytotoxic peptide conjugates are hybrid molecules composed of a peptide carrier which binds to receptor...

The difficulties encountered in the field of machine translation are many. The areas of contact between meaning and the syntactic vehicle expressing it are refractory and pose a problem for linguistic computational research. An applied radical semantics offers some operational solutions for ambiguous syntactic situations. Subject identification within a two-place predicate structure is presente...
