Abstract: Methods and systems of assessing aggregate sentiment over a plurality of time increments of a time period are provided. A maximum aggregation factor that is associated with a particular time period is assigned. A plurality of time increments over the time period are received. For each time increment, the BISV is subtracted from the ISV to form a BISV/ISV difference value. The BISV/ISV difference value is normalized by dividing by the maximum possible difference, thereby determining a modulator. For each time increment, a value is assigned to a recency of the particular time increment to a most recent incremental sentiment value update event, thereby determining a decay factor. The maximum aggregation factor associated with a particular time period is modulated by multiplying a determined modulator and a determined decay factor associated with each time increment within the evaluated time interval.

Abstract: A light-emitting device includes a substrate including a photonic cavity and configured to function as a gate, an active layer including a two-dimensional material, a first conductive contact, and a second conductive contact. The wavelength range of light generated by the light-emitting device may be narrowed based on the photonic cavity being included in the substrate, and the intensity and wavelength range of the generated light may be controlled based on the substrate functioning as a gate.

Abstract: A locally gated graphene nanostructure is described, along with methods of making and using the same. A graphene layer can include first and second terminal regions separated by a substantially single layer gated graphene nanoconstriction. A local first gate region can be separated from the graphene nanoconstriction by a first gate dielectric. The local first gate region can be capacitively coupled to gate electrical conduction in the graphene nanoconstriction. A second gate region can be separated from the graphene nanoconstriction by a second gate dielectric. The second gate region can be capacitively coupled to provide a bias to a first location in the graphene nanoconstriction and to a second location outside of the graphene nanoconstriction. Methods of making and using locally gated graphene nanostructures are also described.

Abstract: Ultralong carbon nanotubes can be formed by placing a secondary chamber within a reactor chamber to restrict a flow to provide a laminar flow. Inner shells can be successively extracted from multi-walled carbon nanotubes (MWNTs) such as by applying a lateral force to an elongated tubular sidewall at a location between its two ends. The extracted shells can have varying electrical and mechanical properties that can be used to create useful materials, electrical devices, and mechanical devices.
