The present invention describes methods and processes for the production of proteins, particularly glycoproteins, by animal cell or mammalian cell culture, illustratively, but not limited to, fed-batch cell cultures. The methods comprise feeding the cells with D-galactose, preferably with feed medium containing D-galactose, preferably daily, to sustain a sialylation effective level of D-galactose in the culture for its duration, thus increasing sialylation of the produced proteins. The methods can also comprise at least two temperature shifts performed during the culturing period, in which the temperature is lower at the end of the culturing period than at the time of initial cell culture. The cell culture processes of the invention involving two or more temperature shifts sustain a high cell viability, and can allow for an extended protein production phase. The methods can also comprise the delayed addition of polyanionic compound at a time after innoculation. Supplementation of the cultures with D-galactose, preferably in a feed medium, to sustain galactose at sialylation effective levels in the cultures until the end of a culture run reverses a decline in sialylation that accompanies culture scale up, and is advantageous for large scale culturing processes.

Voice Quality Enhancement (VQE) is performed directly in a coded domain. A Coded Domain Voice Quality Enhancement (CD-VQE) system modifies at least one parameter of a first encoded signal, resulting in corresponding modified parameter(s). The CD-VQE system replaces the parameter(s) of the first encoded signal with the modified parameter(s), resulting in a second encoded signal. In a decoded state, the second encoded signal approximates a target signal that is a function of at least the first encoded signal in at least a partially decoded state. Thus, the first encoded signal does not have to go through intermediate decode/re-encode processes, which can degrade overall speech quality. The CD-VQE system may cascade functions. Computational resources required for a complete re-encoding are not needed. Overall delay of the system is minimized. The CD-VQE system can be used in networks in which signals are communicated in a coded domain, such as a Third Generation (3G) wireless network.

The quality (e.g., resolution) of image data, video data, and sound data representing a scene or signal is enhanced by a quality enhancement function trained on high quality and low quality representations of a portion of the same scene or signal. The enhancement function is thus optimized to the most relevant input. A training algorithm uses low quality image of a scene or scene portion, along with a high quality image of the same scene or scene portion, to optimize the parameters of a quality enhancement function. The optimized enhancement function is then used to enhance other low quality images of the scene or scene portion. Sound data is enhanced by using a low resolution sample of a portion of a signal, and a high resolution sample of the same signal portion, to train a quality enhancement function which is then used to enhance the remainder of the signal.
