20110300109 | COMPOSITIONS AND METHODS FOR TREATING CANCER - The present invention is based, in part, on our discovery of compositions and methods that can be used to systemically deplete arginine and thereby treat arginine-dependent cancers. Our studies indicate that administering a composition that depletes arginine directly to the patient's small intestine will provide effective treatment for arginine-dependent cancers. Moreover, the methods can be carried out in such a way that various sources of arginine are restricted and side effects are minimized. For example, to deplete arginine, one can not only administer an arginine-depleting enzyme directly to the intestinal lumen but can also inhibit endogenous production of arginine, reduce arginine production by intestinal bacteria and limit arginine intake. To minimize side effects, one can inhibit protein breakdown, which may occur as a compensatory mechanism, provide systemic NO from a nitric oxide donor, provide a pressor peptide, and/or provide prostacycline or an analog thereof. | 12-08-2011 |

20120093337 | Microphone Array - Embodiments of the invention improve upon the prior art array by having more carefully defined directivity functions designed to meet two criteria, being firstly to minimise cross-talk between non-adjacent microphones in the array, and secondly to design the array response such that it approximates stereophonic panning curves that have been shown to provided for good auditory localisation. One embodiment therefore provides a microphone array, comprising N microphones, wherein N is greater than or equal to 3. The microphones are substantially equiangularly arranged over a circular arc subtending an angle ε, wherein ε is less than or equal to 2π, with the directional axes of the N microphones facing substantially radially outwards. Each of the N microphones have a substantially common directivity function Γ(θ) defining the directional response of the microphone, wherein θ=0 is the directional axis, and the directivity function Γ(θ) is arranged such that a sound source in acoustical free field is effectively captured by no more than two consecutive microphones in the array. By arranging the directivity function in this manner crosstalk between non-adjacent microphones can be minimised, which has been shown to improve auditory localisation performance. | 04-19-2012 |
20130202125 | ELECTRONIC DEVICE WITH DIGITAL REVERBERATOR AND METHOD - Electronic devices having digital reverberators are disclosed, together with a method of reproducing sound for a user with the digital reverberator.
