| Method for the treatment of cancer | 20110014303 | 20110120 |
| The invention is based on the surprising finding that treatment with a chemotherapeutic agent such as 5-fluorouracil (5-FU) and an autophagy inducer effectively inhibit the continued growth of, and prevent the recovery following drug withdrawal, of cancer cells. In vivo, drug resistance from a failure to adequately engage in apoptotic programmed cell death leads to a recurrence of cancer and tumours can remain dormant for periods of time before re-emerging as drug resistant metastases. It has been hypothesised that autophagy (Type II cell death) may help cancer cells survive in response to growth limiting conditions, such as nutrient depletion, hypoxia, absence of growth factor, or presence of cytotoxic drug. LiCl is a known autophagy inducer and accelerates cell survival to autophagic programmed cell death.

| Efficient fixed-point approximations of forward and inverse discrete cosine transforms | 20070297502 | 20071227 |
| Techniques are described to approximate computation of an inverse discrete cosine transform using fixed-point calculations. According to these techniques, matrixes of scaled coefficients are generated by multiplying coefficients in matrixes of encoded coefficients by scale factors. Next, matrixes of biased coefficients are generated by adding a midpoint bias value to a DC coefficient of the matrix of scaled coefficients. Fixed-point arithmetic is then used to apply a transform to the matrixes of biased coefficients. Values in the resulting matrixes are then right-shifted in order to derive matrixes of pixel component values. Matrixes of pixel component values are then combined to create matrixes of pixels. The matrixes of pixels generated by these techniques closely resemble matrixes of pixels decompressed using the ideal inverse discrete cosine transform (“IDCT”).
