  • Patent number: 11031094
    Abstract: The present invention is an accelerated conformational sampling method for predicting target peptide and protein structures comprising a process of determining energy minimized synthetic templates using a simple system for modeling individual molecular bonds within the subject peptide or protein. Use of these synthetic templates greatly reduces the computational resources necessary for optimally determining structural features of the target peptide or protein. The present invention also provides methods for rapid and efficient analysis of the effect of mutations on target peptides and proteins.

  • Publication number: 20200313775
    Abstract: Consistent with an aspect of the present disclosure, electrical signals or digital subcarriers are generated in a DSP based on independent input data streams. Drive signals are generated based on the digital subcarriers, and such drive signals are applied to an optical modulator, including, for example, a Mach-Zehnder modulator. The optical modulator modulates light output from a laser based on the drive signals to supply optical subcarriers corresponding to the digital subcarriers. These optical subcarriers may be received by optical receivers provided at different locations in an optical communications network, where the optical subcarrier may be processed, and the input data stream associated with such optical subcarrier is output. Accordingly, instead of providing multiple lasers and modulators, for example, data is carried by individual subcarriers output from an optical source including one laser and modulator. Thus, a cost associated with the network may be reduced.

  • Patent number: 10070206
    Abstract: A method may include transmitting, by an optical device, a first set of channels using a first modulation format. The first set of channels may be attenuated during transmission by a filter associated with a wavelength selective switch. The method may further include transmitting, by the optical device, a second set of channels using a second modulation format. The second set of channels may be attenuated during transmission by the filter associated with the wavelength selective switch. The first set of channels and the second set of channels may be included in a super-channel. The first modulation format may be selected based on a first signal quality factor associated with attenuation by the filter associated with the wavelength selective switch. The second modulation format may be selected based on a second signal quality factor associated with attenuation by the filter associated with the wavelength selective switch.

  • Patent number: 9485012
    Abstract: An optical transmitter may include one or more lasers configured to provide a primary optical signal having a primary wavelength and a secondary optical signal having a secondary wavelength to a modulator via corresponding first and second modulator inputs. The modulator may combine the primary and secondary optical signals into a combined optical signal and modulate, with an electrical signal, the combined optical signal to provide a modulated optical signal to an optical filter. The optical filter may be configured to separate, from the modulated optical signal, a modulated primary optical signal having the primary wavelength and a modulated secondary optical signal having the secondary wavelength and provide the modulated primary optical signal to a primary optical link and the modulated secondary optical signal to a secondary optical link.
