Filed:

Jun 28, 2001

Appl. No.:

09/894630

Inventors:

C. Peter Romaine - State College PA, US
Xi Chen - Durham NC, US

Assignee:

The Penn State Research Foundation - University Park PA

International Classification:

C12N001/14
C12N001/16
C12N001/18
C12N015/74
C12N015/82

US Classification:

43525411, 435243, 435440, 435471, 435469, 536 231

Abstract:

Applicants have devised a highly effective, convenient, and expeditious genetic transformation system for filamentous fungi, such as. The preferred method uses an -mediated transformation protocol. The critical features of this protocol include co-cultivation of the bacterium with fruit body tissue instead of spores. In a preferred embodiment, even higher transformation efficiencies were observed with the use of a homologous promoter in the polynucleotide expression construct in order to drive gene expression.

US Classification:

375147, 455334, 375340, 375E01002

Abstract:

A system is provided. The system comprises a transform domain radio receiver comprising a plurality of reconfigurable processing paths coupled to a radio frequency signal input, each reconfigurable processing path implementing a down converter, a low-pass filter, and an integrator and wherein a frequency selectivity of the processing path is reconfigurable. The system also comprises a control unit to configure a frequency selectivity of the plurality of parallel reconfigurable processing paths.

International Classification:

G02F 1/295

Abstract:

Embodiments relate to a photonic component having a metasurface. The metasurface includes a substrate with a thin-layer of meta-atoms disposed thereon. The photonic component includes a waveguide having a top surface, wherein the metasurface is disposed on at least a portion of the top surface such that the meta-atoms form an array on the top surface. The photonic component includes a sandwich nano-bar antenna formed in or on the metasurface.
