Abstract: Immune-potentiating compositions include cells exhibiting enhanced antigen-presenting functions. The compositions are generally useful in facilitating the stimulation of host immune cell responses, including selective and targeted immune cell responses, and are particularly useful in the treatment and/or prophylaxis of cancers, tumors and pathogenic infections.

Abstract: Systems and methods for autonomous signal modulation format identification are disclosed. In an example embodiment of the disclosed technology, a method includes applying higher-order statistics to an input signal to identify the input signal's modulation format. The method may include applying higher-order statistics to the input signal to calculate higher-order cumulant values for the input signal as higher-order cumulants are indicative of a particular modulation format signature. The method may further include employing a decision tree to determine the modulation format of the input signal.

Abstract: A switched mode class-S power amplifier comprises a sigma-delta modulator with a digital input, a power switch connected to the output of the sigma-delta modulator providing the power amplifier output, and a feedback mechanism. The sigma-delta modulator has a high-pass transfer function and uses an offset switching frequency to remove an unwanted image over half of the switching frequency. The amplifier may have a filter to remove unwanted fold-over image. There may be at least two modulators arranged in parallel, and there may be a complex filter for constructively combining the modulator outputs.

Abstract: A method of separation and/or recovery of a precious metal from a solution containing said precious metal in ionic form, optionally in the presence of impurities, including the step of contacting a solution containing said precious metal in ionic form with a conducting polymer. The method is generally applicable to precious metals including platinum (Pt), palladium (Pd) and more particularly gold (Au). The ionic species may be anionic (for example [AuCl4]?) or cationic. The polymer may be for example, a polypyrrole or polythiophene, optionally doped and are preferably in a high surface area form eg. coated onto cloth or RVC or in self supporting colloidal form. The polymer may also contain species to give further functionality, eg magnetic or heat sensitive species.

Abstract: Data throughput rates are increased in an optical fiber communication system without requiring replacement of the existing optical fiber in a link. Channel throughput is increased by upgrading the components and circuitry in the head and terminal of an optical fiber communication system link. Aggregate throughput in a fiber optic link is increased beyond the range of conventional Wavelength Division Multiplexed (WDM) upgrades, while precluding the necessity of replacing existing fiber plants. The increase in system throughput is achieved by using advanced modulation techniques to encode greater amounts of data into the transmitted spectrum of a channel, thereby increasing the spectral efficiency of each channel. This novel method of increasing transmission capacity by upgrading the head and terminal of the system to achieve greater spectral efficiency and hence throughput, alleviates the need to replace existing fiber plants.

Abstract: The present invention discloses immunomodulating compositions. More particularly, the present invention discloses compositions comprising an immune-modulating agent and a lectin-interactive agent, which are useful for stimulating and prolonging host immune cell responses. The compositions of the present invention are particularly useful in the treatment and/or prophylaxis of a range of conditions including pathogenic infections, autoimmune diseases, transplant rejection, graft versus host disease, allergies, inflammatory disease, as well as cancers and tumours.

Abstract: Decreasing the average transmitted power in an optical fiber communication channel using multilevel amplitude modulation in conjunction with Pulse Position Modulation (PPM). This multilevel PPM method does not entail any tradeoff between decreased power per channel and channel bandwidth, enabling a lower average transmitted power compared to On/Off Keying (OOK) with no reduction in aggregate data rate. Therefore, multilevel PPM can be used in high-speed Dense Wavelength Division Multiplexed (DWDM) systems where the maximum number of channels is traditionally limited by nonlinear effects such as self-phase modulation (SPM), cross-phase modulation (XPM), four-wave mixing (FWM), stimulated Brillouin scattering (SBS), and stimulated Raman scattering (SRS). This modulation technique can enable an increased number of channels in DWDM systems, thereby increasing aggregate data rates within those systems.
