Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

Abstract: A semiconductor device includes a fin structure. A source/drain region is formed on the fin structure. A first gate structure is disposed over the fin structure. A source/drain contact is disposed over the source/drain region. The source/drain contact has a protruding segment that protrudes at least partially over the first gate structure. The source/drain contact electrically couples together the source/drain region and the first gate structure.

Abstract: Monoclonal antibodies against human Mac-1 are provided. These antibodies can bind to different states of Mac-1 so as to alter the biofunctions of Mac-1. These antibodies can modulate Th1/Th2 cytokine secretions by TLR-activated immune cells and can be used for the treatments of diseases related to acute and chronic inflammatory disorders, such as infectious diseases, and cancers.

Abstract: A laptop computer includes a base, a touch screen, a first hinge structure and a second hinge structure. The first hinge structure is pivotally connected with a side of the base. The second hinge structure is pivotally connected with the first hinge structure. The second hinge structure includes a locking part. The locking part detachably fastens to the touch screen. When the locking part fastens to the touch screen and the angle between the touch screen and the base is within 0 degree and a predetermined angle, the second hinge structure rotates relative to the first hinge structure. When the locking part fastens to the touch screen and the angle between the touch screen and the base is larger than the predetermined angle, the first hinge structure and the second hinge structure rotate synchronously relative to the base.
