Abstract: Provided is a functional edible oil (FEO), a preparation method therefor and use thereof. The FEO is prepared by ternary transesterification of medium-chain triglycerides (MCTs), oils rich in linoleic acid, and oils rich in linolenic acid. The fatty acid composition and distribution of the FEO were determined and optimized via comparative analysis of indexes such as melting point, and effect of improving glucose and lipid metabolism as determined by animal tests. The FEO has a mass ratio of 2.3 to 4.0 for medium chain fatty acids (MCFAs) in MCTs to long chain fatty acids (LCFAs) in the oils rich in linoleic acid, and oils rich in linolenic acid and a mass ratio of 0.5 to 1.0 for linoleic acid to linolenic acid in the LCFAs, by mass of fatty acids. The FEO is added to food products at ?18.00%.

Abstract: A beam adjustment assembly includes a phase shifter and a connecting plate. The phase shifter includes a circuit board and main dielectric slabs configured to shift a phase. The circuit board is provided with a first strip and a second strip that are spaced. The first strip and the second strip are configured to respectively connect to radiating elements of an antenna. The connecting plate is slidably assembled on the circuit board and is configured to control an electrical connection between the first strip and the second strip. When sliding, the main dielectric slab can push the connecting plate to slide to control a quantity of radiating elements in the antenna system. The sliding of the main dielectric slab in the phase shifter is used as a driving mechanism of the connecting plate.

Abstract: Disclosed is a base oil for functional food oils and fats, a preparation method therefor and the use thereof. The base oil for functional food oils and fats is formed through ternary transesterification on medium-chain triglycerides, high-melting-point fat and oils rich in linolenic acid. The base oil for functional food oils and fats has a wide melting range, can significantly improve the glucose and lipid metabolism disorder, balance the essential and functional fatty acids in the body, and quickly replenish energy. Animal experiments were conducted and the fatty acid composition and distribution of the base oil were optimized and determined through comparative analysis based on evaluation indicators such as the improved effect in glucose and lipid metabolism and melting point.

Abstract: Apparatuses, systems, and methods for providing maximum transmit power control when utilizing multiple radio access technologies. For example, a wireless communication device comprising two cellular radios may intend to transmit on the first radio, while concurrently transmitting on the second radio. To ensure compliance with a maximum transmit power limitation, the device may determine an allowed transmit power level of the first radio, representing a difference between the maximum transmit power limitation and the current transmit power level being transmitted by the second radio. The device may also determine a threshold power level for a communication by the first radio. If the allowed transmit power level meets the threshold power level, then the device may transmit the first communication having a power level between the threshold power level and the allowed transmit power level. Otherwise, the device may forego transmission of the first communication.

Abstract: A method for the enzymatically catalyzed synthesis of a diol from an amino acid includes enzymatically hydroxylating the amino acid, enzymatically deaminating the amino acid, the deamination resulting in the formation of an oxo group at the position of the amino group, enzymatically decarboxylating the amino acid, and enzymatically hydrogenating the oxo group resulting from the deamination reaction.

Abstract: The invention is partly based on the unexpected discoveries of cellular differences in response to pH alterations, and a key role of the cells' proliferative statuses in determining their responses. Thus, pH modifiers, their doses and dosing regimens are chosen to selectively deplete and/or suppress inflammatory and/or non-inflammatory pathological cells and their proliferation while preserving normal cells in diseases whose pathogenesis is partially or fully attributable to inflammation and/or cell proliferation. Conversely, pH modifiers, their doses and dosing regimens were chosen to selectively increase the population and/or proliferation of normal cells to promote protective immune and inflammatory responses, normal cell regeneration or renewal.
