The present invention is directed to plant genetic engineering. In particular, it relates to methods of modulating cytokinin related processes in a plant and selecting a plant having a phenotype associated with an altered cytokinin-related process.

A wireless microelectromechanical system (MEMS) pressure sensor with built in calibration. An actuator is coupled with a pressure sensing device to enable the pressure to be calibrated against the known pressure exerted by the actuator. The sensing component is configured to flex under the application of force to a pure bending condition, i.e., the sensing component flexes with no or insignificant shear forces in the sensing component.

Some embodiments disclosed herein provide a signal decoder with a general purpose calculation engine. A system for decoding signals in a wireless communication system can include: a controller including an instruction counter; a program memory configured to store program code for operating the controller; a general purpose calculation engine configured to perform primitive operations derived from algorithms for decoding a plurality of coded signals received via a plurality of receive antennas; and a data memory connected to the general purpose calculation engine for storing data generated by the general purpose calculation engine while performing the primitive operations.

A multiband antenna system is provided. The system includes a substrate; an antenna which is disposed on a first side and a second side of the substrate, and produces a resonance in a plurality of frequency bands; a plurality of feeders which are disposed on the first side of the substrate; and a filter which is disposed on the first side of the substrate, is coupled to an end of the antenna, and transfers signals of the plurality of frequency bands output from the antenna to respective feeders of the plurality of the feeders.

Protein logic gates are made from autoregulated fusion proteins comprising an output domain and a plurality of input domains, wherein at least one of the input domains is heterologous to the output domain, and the input domains interact with each other to allosterically and external, ligand-dependently regulate the output domain. The output domain may be constitutively active, and in the absence of the ligand, the input domains interact to inhibit the output domain. The activity of the output domain is user discretionary, and may include activities that are catalytic, label-generative, metabolic-regulative, apototic, specific-binding, etc. Multiple input domains can cooperatively regulate the fusion protein in a wide variety of functionalities, including as an OR-gate, an AND-gate, and an AND-NOT-gate. The gates may be incorporated into cells and therein used to modulate cell function.
