Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: Applications of butylidenephthalide (BP), comprising the use of BP in providing a kit for promoting differentiation of stem cells into brown adipose cells, and the use of BP in preparing a medicament, wherein the medicament is used for inhibiting the accumulation of white adipose cells, promoting the conversion of white adipose cells into brown adipose cells, inhibiting weight gain and/or reducing the content of triglycerides, glucose, and total cholesterol in blood.

Abstract: A computer-implemented method for automatically pausing advertisements based on user attention includes rendering a digital video to a user, in response to the user initiating the digital video through a web multimedia player. The computer-implemented method also includes streaming an advertisement to the user once the user begins to watch the digital video and monitoring the user attention as the user watches the advertisement. The user attention is monitored based on keystrokes and mouse movements. Further, the computer-implemented method includes detecting one or more changes in the user attention. Furthermore, the computer-implemented method includes pausing the advertisement automatically at instance of detecting the one or more changes. Moreover, the computer-implemented method includes detecting the one or more changes that directs the user attention to the paused advertisement and resuming streaming of the advertisement.
