This paper deals with transmission theory of plane electromagnetic waves in free space and in cylindrical regions of arbitrary cross section. Transmission properties of such waves can be expressed very simply in the same terms as the properties of electric waves guided by a pair of parallel wires. The earlier parts of the paper are concerned with general theorems and the latter parts with their...

Recently developed novel high-strength sorbite stainless steel (S600E) integrates the merits of exceptional mechanical properties, high corrosion resistance, effortless weldability, and cost-effectiveness, offering remarkable competitiveness in structures. However, lack information regarding its performance impedes application as a structural component construction industry. In this paper, mate...

Abstract This paper experimentally and numerically investigated the impact test response characteristics of circular honeycomb cores. The experiments were conducted on two different structures aluminum-tube core, square structure star structure. specimens tested in order to find energy absorption, specific crashworthiness behaviors. results revealed that cores with could resist higher load than...

Several new branched (1, 2), circular (9) and looped oligonucleotides (14-17) were synthesized. 3'-Deoxypsicothymidine was employed to create the site of branching when required. The circular and looped structures were obtained by oxidative disulfide bond formation between mercaptoalkyl tether groups. All the oligonucleotides prepared contained two T11 sequences, and the branched and looped oli...
