    Abstract: Disclosed herein are exemplary methods, apparatus, and systems for performing timing-aware automatic test pattern generation (ATPG) that can be used, for example, to improve the quality of a test set generated for detecting delay defects or holding time defects. In certain embodiments, timing information derived from various sources (e.g. from Standard Delay Format (SDF) files) is integrated into an ATPG tool. The timing information can be used to guide the test generator to detect the faults through certain paths (e.g., paths having a selected length, or range of lengths, such as the longest or shortest paths). To avoid propagating the faults through similar paths repeatedly, a weighted random method can be used to improve the path coverage during test generation. Experimental results show that significant test quality improvement can be achieved when applying embodiments of timing-aware ATPG to industrial designs.

    Abstract: A spiral wound membrane element and a method for cleaning a spiral wound membrane sheet are provided. The spiral wound membrane element comprising a perforated central tube; one or more membrane sleeves, each sleeve comprising two membrane sheets enclosed at two edges around a feed spacer sheet and wrapped around the central tube; a permeate carrier sheet attached to the central tube at a first edge opposite a second edge; and a seal on third and fourth edges of the permeate carrier sheet. The method comprises introducing two solution with different solute concentration to two sides of the spiral wound membrane sheet; establishing a concentration gradient between the first and second sides; communicating a first solvent from the first side to the second side to remove a foulant located on the second side of the membrane sheet; and collecting a waste stream that contains the foulant.

    Abstract: A stroller frame has a body, two front wheel assemblies, a seat supporting mechanism, and a rear wheel folding mechanism. The two front wheel assemblies are respectively and pivotally disposed on the body. The seat supporting mechanism is moveably disposed below a seat plate of the body. The rear wheel folding mechanism is disposed on a rear side of the body and has two rear wheel assemblies and two linkage assemblies. The two rear wheel assemblies are moveably disposed on a first transverse rod of the body. The two linkage assemblies are respectively disposed on two ends of a second transverse rod of the body. When the stroller frame is folded, two rear wheels of the two rear wheel assemblies move between two front wheels of the two front wheel assemblies to decrease the overall width and volume of the folded stroller frame.

The multi-stage tubing includes a first-stage and a second-stage. The first-stage has a first end connected to an output port of the pneumatic pulse generator, a second end opposite the first end, and a first inner channel for transmitting the pressure pulses to the surgical cutter. The first inner channel has a first cross-sectional area. The second-stage has a first end in pneumatic communication with the second end of the first-stage, a second end opposite the first end of the second-stage, and a second inner channel for transmitting the pressure pulses to the surgical cutter. The second inner channel has a second cross-sectional area that is different than the first cross-sectional area.

    Abstract: A method for growing a graphene nanoribbon on an insulating substrate having a cleavage plane with atomic level flatness is provided, and belongs to the field of low-dimensional materials and new materials. The method includes the following steps. Step 1: Cleave an insulating substrate to obtain a cleavage plane with atomic level flatness, and prepare a single atomic layer step. Step 2: Directly grow a graphene nanoribbon on the insulating substrate having regular single atomic steps. In the method, a characteristic that nucleation energy of graphene on the atomic step is different from that on the flat cleavage plane is used, and conditions, such as the temperature, intensity of pressure and supersaturation degree of activated carbon atoms, are adjusted, so that the graphene grows only along a step edge into a graphene nanoribbon of an adjustable size. The method is mainly applied to the field of new-type graphene optoelectronic devices.

    Abstract: The present disclosure relates to a slurry distribution system having a distribution tube connected between a mixing tank and a CMP tool. The mixing tank is configured to generate a polishing mixture comprising a diluted slurry having abrasive particles that enable mechanical polishing of a workpiece. The polishing mixture is transported between the mixing tank and a CMP tool by way of a transport piping. An energy source, in communication with the transport piping, transfers energy to the abrasive particles within the polishing mixture, thereby preventing accumulation of the abrasive particles within the transport piping.
