Abstract: The present disclosure provides a privacy computing method based on homomorphic encryption, which includes steps as follows. The ciphertext data is received, where the ciphertext data has a floating-point homomorphic encryption data structure, and the floating-point homomorphic encryption data structure of the ciphertext data includes the ciphertext mantissa, exponent parameter and gain parameter. The gain parameter sets the precision of the floating point corresponding to the ciphertext mantissa. The exponent parameter is adapted to multiplication or division. The artificial intelligence model performs operations on the ciphertext data to return the ciphertext result.

Abstract: A memory array and an operation method of the memory array are provided. The memory array includes first and second ferroelectric memory devices formed along a gate electrode, a channel layer and a ferroelectric layer between the gate electrode and the channel layer. The ferroelectric memory devices include: a common source/drain electrode and two respective source/drain electrodes, separately in contact with a side of the channel layer opposite to the ferroelectric layer, wherein the common source/drain electrode is disposed between the respective source/drain electrodes; and first and second auxiliary gates, capacitively coupled to the channel layer, wherein the first auxiliary gate is located between the common source/drain electrode and one of the respective source/drain electrodes, and the second auxiliary gate is located between the common source/drain electrode and the other respective source/drain electrode.

Abstract: Constipation is a common and serious problem for terminal cancer patients, often resulting in deterioration of the overall condition of the patients and causing great anxiety in their family members. Terminal cancer patients, according to the principle of palliative care and the symptoms of pain, are usually given morphine-like analgesics orally or by injection to ease the pain, and are therefore very likely to suffer from constipation, poor appetite, bloating and other relevant symptoms. The Chinese herbal composition of rhubarb and licorice extracts presented in this study can notably improve the symptoms of constipation, poor appetite, and bloating, and these results are statistically significant.
