Abstract: A vehicle seat assembly, suitable for vehicles such as locomotives and the like, includes a main cushion body and a lifting cushion. The main cushion body has a sliding cushion connected to a vehicle body with a sliding structure. The lifting cushion is connected to the vehicle body with a linkage mechanism. The lifting cushion is moved into a carriage when the sliding cushion is in a first position, and when the sliding cushion slides laterally into a second position to form a space portion, the lifting cushion can be lifted from the carriage and moved into the space portion and then positioned, or can be lowered into the carriage again, so that the sliding cushion can be moved back to the first position, thereby allowing the user to adjust seat cushion length according to their needs.

Abstract: Semiconductor structures and methods of forming the same are provided. An exemplary method incudes forming a first dielectric layer over a first conductive feature, forming a conductive via extending through the first dielectric layer and coupled to the first conductive feature, forming a hard mask layer over the conductive via, patterning the hard mask layer to form a first opening exposing the first dielectric layer; forming a sacrificial layer to partially fill the first opening, forming a porous dielectric layer on the sacrificial layer, after the forming of the porous dielectric layer, selectively removing the sacrificial layer to form an air gap, forming a second dielectric layer over the porous dielectric layer, and replacing a portion of the patterned hard mask layer disposed directly over the conductive via with a second conductive feature.

Abstract: An interconnection structure and a manufacturing method thereof are provided. The interconnection structure includes a first dielectric layer, a first conductive feature, a second dielectric layer, and a barrier layer. The first conductive feature is disposed on the first dielectric layer, the second dielectric layer is disposed on the first dielectric layer and surrounds the sidewalls of the first conductive feature, the barrier layer is disposed between the first dielectric layer and the second dielectric layer and between the sidewalls of the first conductive feature and the second dielectric layer.

Abstract: A semiconductor structure is provided. The semiconductor structure includes a first low dielectric constant (low-k) layer, a first metal layer, a metal cap layer, a dielectric on dielectric (DoD) layer, an etch stop layer (ESL), a second low-k layer, a metal via and a second metal layer. The dielectric constant of the first low-k layer is less than 4. The first metal layer is embodied in the first low-k layer. The first low-k layer exposes the first metal layer. The metal cap layer is disposed on the first metal layer. The DoD layer is disposed on the first low-k layer. The etch stop layer is disposed on the metal cap layer and the DoD layer. The second low-k layer is disposed above the etch stop layer. The metal via is embodied in the second low-k layer and connected to the first metal layer.

Abstract: A drug conjugate includes a structure shown by the following formula: Z-(linker-[R]m)n. In the formula, Z is a drug compound, R is a sugar, and m and n are independently an integer from 1 to 6. The drug compound Z is a hepatitis virus targeting drug, a hepatitis B virus (HBV) drug, an inhibitor of apoptosis protein (IAP) antagonist, a multidrug resistance (MDR) inhibitor, or analogues, precursors, prodrugs, derivatives thereof.
