Abstract: The invention relates to the treatment of bone disorders. In particular, the invention provides an approach involving administration of a high initial dose or doses of an sclerostin antibody to bring about a rapid increase in bone formation, followed by administration of lowers doses of the antibody to give a sustained lower rate of bone formation after the initial burst of bone formation. The invention also provides an approach involving decreasing dosing frequency with such an antibody to control bone formation. The approaches may be used in particular in those subjects who would benefit most from such an initial rapid burst of bone formation. Examples of such subjects include subjects who have been recently diagnosed or are experiencing severe symptoms of the disorder, as well as those subjects who have been administered a different treatment for the bone disorder which is proving ineffective. The approaches may be used in combination with each other.

Abstract: Provided is a system and a method for low-temperature treatment of heavy metals and dioxins in fly ash. In the present disclosure, the fly ash is subjected to tertiary water washing and then separation by pressure filtration with a plate and frame filter press to obtain fly ash after the tertiary water washing. A low-temperature heat treatment is conducted on the fly ash after the tertiary water washing in a stirring reactor by adding an additive combination. Chlorine salts in the fly ash can be effectively removed by the tertiary water washing, which avoids the chlorination of a precursor in the fly ash to form dioxins during the low-temperature pyrolysis, thereby improving a heat reduction efficiency of the dioxins in the fly ash. Moreover, the reduction of a chlorine content in the fly ash can also avoid deactivation of the additives and improve a solidification effect of the heavy metals.

Abstract: In a broadband wireless communication system, a spread spectrum signal is intentionally overlapped with an OFDM signal, in a time domain, a frequency domain, or both. The OFDM signal, which inherently has a high spectral efficiency, is used for carrying broadband data or control information. The spread spectrum signal, which is designed to have a high spread gain for overcoming severe interference, is used for facilitating system functions such as initial random access, channel probing, or short messaging. Methods and techniques are devised to ensure that the mutual interference between the overlapped signals is minimized to have insignificant impact on either signal and that both signals are detectable with expected performance by a receiver.
