Various examples of methods and systems are provided for direct closed-form finite alphabet constant-envelope waveforms for planar array beampatterns. In one example, a method includes defining a waveform covariance matrix based at least in part upon a two-dimensional fast Fourier transform (2D-FFT) analysis of a frequency domain matrix H.sub.f associated with a planar array of antennas. Symbols can be encoded based upon the waveform covariance matrix and the encoded symbols can be transmitted via the planar array of antennas. In another embodiment, a system comprises an NM planar array of antennas and transmission circuitry configured to transmit symbols via a two-dimensional waveform beampattern defined based at least in part upon a 2D-FFT analysis of a frequency domain matrix H.sub.f associated with the planar array of antennas.

Isolated peptides comprising one or more antigenic sites of filovirus glycoprotein and methods of their use and production are disclosed. Nucleic acid molecules encoding the peptides are also provided. In several embodiments, the peptides can be used to induce an immune response to filovirus glycoprotein, such as Zaire ebolavirus glycoprotein, in a subject, for example, to treat or prevent infection of the subject with the virus.

Disclosed are chimeric polypeptides based on viral membrane fusion proteins. More particularly, the present invention discloses chimeric polypeptides that comprise a virion surface exposed portion of a viral fusion protein and a heterologous structure-stabilizing moiety, and to complexes of those chimeric polypeptides. The present invention also discloses the use of these complexes in compositions and methods for eliciting an immune response to a fusion protein of an enveloped virus, or complex of the fusion protein, and/or for treating or preventing an enveloped virus infection. The present invention further discloses the use of the heterologous structure-stabilizing moiety for oligomerizing heterologous molecules of interest.

The present invention relates to polyclonal antibodies for use in the prevention and/or treatment of the Ebola virus disease. In one embodiment, the polyclonal antibodies are specific for a truncated Ebola virus GP glycoprotein. Said polyclonal antibodies are preferably non-human antibodies and are provided in a serum free pharmaceutical composition. The present invention also relates to a method of prevention and/or treatment of Ebola virus disease in a subject in need thereof, comprising administering to said subject polyclonal antibodies specific for the Ebola virus.

The invention provides compositions, kits and methods utilizing polypeptides having a viral alpha-helix heptad repeat domain in a stabilized -helical structure (herein also referred to as SAH). The compositions are useful for treating and/or preventing viral infections. The invention is based, at least in part, on the result provided herein demonstrating that viral hydrocarbon stapled alpha helical peptides display excellent proteolytic, acid, and thermal stability, restore the native alpha-helical structure of the peptide, are highly effective in interfering with the viral fusogenic process, and possess superior pharmacokinetic properties compared to the corresponding unmodified peptides.
