The invention discloses an anti-aging composition. The composition comprises a foundational component and anti-aging factors dispersed in the foundational component, wherein the anti-aging factors are at least three of soybean germ extract, wheat germ extract, safflower germ extract and maize germ extract. At least three of the soybean germ extract, wheat germ extract, safflower germ extract and maize germ extract are applied to the anti-aging composition and have a synergistic anti-aging effect to synergistically promote synthesis of collagen, quickly smooth fine line on the skin and repair damaged skin, so that the aim of delaying skin senescence can be achieved.

Methods for the prevention or treatment of disorders and complications of disorders resulting from cell damage caused by an aging-related isoform of NADH oxidase (arNOX) are described. The agent for such inhibition comprises processed various Narcissus tazetta extracts, preferably IBR-DORMIN®, both alone and in combination with other inhibition agents, including ubiquinones like coenzyme Q. These agents bind arNOX and inhibit the ability of arNOX to generate reactive oxygen species, thereby decreasing the ability of arNOX to generate reactive oxygen species. Such agents, and their methods of administration, as extremely effective as part of anti-aging treatments.

A reliability-based opportunity preventive maintenance optimization model for key components of trains comprises firstly establishing an opportunity preventive maintenance model of the key componentsof a train and a constraint condition thereof, and then obtaining an opportunity service age factor and an opportunity maintenance threshold according to the partial least squares regression method, comprising the steps as follows: firstly initializing the parameters; solving the maintenance service age by the initial value of the preventive maintenance reliability; then using the partial least squares regression method to optimize the model to solve the opportunity service age factor; determining whether the preventive maintenance service age of the component k meets the opportunity maintenance condition, if so, determining whether the component k lacks maintaining or is over-maintained, if not, performing opportunity maintenance on the component k; determining whether the total maintenance service age of the component i is less than or equal to the intended operation cycle; and finally solving the minimum maintenance cost according to the model. The method for the model has fast calculation speed and high solution precision, and the optimized model is capable of effectively reducing the maintenance cost of key components of the train.

An organic light emitting diode (OLED) pixel circuit includes a driving node, a pixel driving unit, an electroluminescent device, and a compensation unit. The pixel driving unit is coupled to a data line receiving a data voltage and provides a driving voltage to the driving node. The display electroluminescent device is coupled to the driving node for illuminating in response to the driving voltage, wherein the level of the driving voltage is related to an aging factor voltage, corresponding to a usage time of the display electroluminescent device. The compensation unit, including a compensation electroluminescent device, is couple to the driving node and drives the compensation electroluminescent device to illuminate in response to the driving voltage, so as to compensate the aging decay of the display electroluminescent device with the electroluminescent compensation unit.

Systems and methods for estimating an efficiency of a catalyst placed in an exhaust path of a combustion engine are disclosed. In one example approach, a method comprises: ageing the catalyst consecutively at different temperatures for definite time periods; measuring the catalyst conversion efficiency after each ageing step; calculating the ageing factor for each step of the ageing procedure and the accumulative value of the ageing factors for all steps of the ageing procedure; estimating catalyst efficiency correlation factors related to the measured catalyst conversion efficiency for each temperature point and for all ageing conditions; determining a correlation between the catalyst efficiency correlation factors and the accumulative value of the ageing factors; and calculating the conversion efficiency of the aged catalyst based on a predetermined correlation between the accumulative ageing factor and the catalyst efficiency correlation factor.
