A method and apparatus to provide blooming protection for a pixel in an array while extending dynamic range.

Systems and methods are described in which both a quantum key distribution (QKD) transmitter and QKD receiver may keep both of their two-path interferometers stable, with regard to path length drift, relative to an internal reference laser are described. Systems and methods are also proposed whereby the transmitter interferometer may have only a single path (e.g., Sagnac interferometers). The systems and methods described herein may greatly improve the performance of quantum cryptographic transceivers that may make use of these systems and methods.

A space is set substantially in a tropical rain forest type environment to activate a human's essential brain region and realize an environment suitable for the human's brain by arranging a device for setting the tropical rain forest type environment based on characteristics of activating human's essential brain region responsive to tropical rain forest type environment information, in a space such as an urban space, a housing space or other living space. The tropical rain forest type environmental information has higher density and higher complexity than those of urban space type environmental information, and includes at least one of auditory information, visual information, and super perceptual information of aerial vibration. The tropical rain forest type environmental information is comfortable for the human with no excessive stress, and is environmental information for effecting prevention and treatment of diseases due to stress by realizing the environment comfortable for the human's brain.

Methods and systems for attention-based rendering on an entertainment system are provided. A tracking device captures data associated with a user, which is used to determine that a user has reacted (e.g., visually or emotionally) to a particular part of the screen. The processing power is increased in this part of the screen, which increases detail and fidelity of the graphics and / or updating speed. The processing power in the areas of the screen that the user is not paying attention to is decreased and diverted from those areas, resulting in decreased detail and fidelity of the graphics and / or decreased updating speed.

Methods and compositions for replication of threose nucleic acids (TNAs) are described. The described methods include a method for transcribing a DNA template into a TNA, and a method for reverse transcribing a threose nucleic acid into a cDNA.

A method of constructing an optimized network simulation environment according to the present invention includes the steps of identifying communication equipment models for relaying a message to / from real equipments out of communication equipment models within a network model, as major models, calculating the order of abstraction priority for major models, performing batch-mode abstraction for non-major models, driving a simulation, determining whether a difference between a simulation execution time and an actual time spent is within an allowable delay value, performing adaptive abstraction for the major models, and evaluating a result of the simulation. If the method according to the present invention is used, a real-time simulation having fidelity and reliability for the function and operation of real equipments can be guaranteed.
