Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for analyzing hardware designs for vulnerabilities to side-channel attacks. One of the methods includes receiving a request to analyze a device hardware design for side-channel vulnerabilities in the device after being manufactured. Physical characteristics data is obtained representing one or more physical characteristics of the device based on the device hardware design. Information flow analysis is performed to identify one or more signals of interest corresponding to digital assets. From the physical characteristics data and the one or more signals of interest, data representing potentially vulnerable signals in the device hardware design is generated. A leakage model is generated for the potentially vulnerable signals that quantifies one or more leakage criteria for one or more structures of the device hardware design.

Abstract: A guidewire system for spine surgeries includes a first guidewire portion having an elongate first guidewire body with a distal end and a proximal end. A threaded male fastener at the distal end of the first guidewire body is configured to fasten to a vertebra of a spine of a subject and a threaded female coupler at the proximal end of the first guidewire body defines a threaded opening. The guidewire system includes a second guidewire portion having an elongate second guidewire body with a distal end and a proximal end. A threaded male coupler at the distal end of the second guidewire body is configured to thread into the threaded female coupler of the first guidewire portion to fasten the second guidewire portion to the first guidewire portion to form an elongate guidewire.
