With the globalization of integrated circuit (IC) design flow and the outsourcing of chip fabrication service, intellectual property (IP) piracy and malicious logic insertion become main security threats to tamper hardware infrastructures. While most of the protection methods are dedicated for digital circuits, we try to protect radio-frequency (RF) designs which are more likely to be IP piracy...

Weighted finite automata (WFA) are used with FPGA accelerating hardware to scan large genomic banks. Hardwiring such automata raises surface area and clock frequency constraints, requiring efficient ε-transitions-removal techniques. In this paper, we present bounds on the number of new transitions for the development of acyclic WFA, which is a special case of the ε-transitions-removal problem. ...

Weighted finite automata (WFA) are used with accelerating hardware to scan large genomic banks. Hardwiring such automata raise surface area and clock frequency constraints, requiring efficient ε-transitions-removal techniques. In this paper, we present new bounds on the number of new transitions for several ε-transitions-removal problems. We study the case of acyclic WFA. We introduce a new pro...

Entrapment and fracture of carotid angioplasty and stenting hardware is a rare complication of percutaneous stenting procedures. We describe a case of a retained distal filter embolic protection device and guidewire in a 57-year-old male in Beijing, China. After unsuccessful attempts at removal via interventional methods, a second stent was deployed to secure the original hardware in situ, and ...

background implant removal is a common procedure in orthopedic surgery which can be associated with many complications such as scar formation, hematoma, nerve injury, infection, and refracture. indications for orthopedic implant removal have declined in recent years. most studies have considered orthopedic hardware removal as an unnecessary procedure in the absence of severe complications such ...

Embedded systems based on different types of hardware platforms are nowadays increasingly used in safety-critical applications. These different hardware platforms lead to fundamental differences in design, particularly regarding the corresponding software. In this work, potential influences of hardware platforms on safety properties were gathered and open issues were identified. The most releva...

BACKGROUND Infection is a serious complication of cardiovascular-implantable electronic device implantation and necessitates removal of all hardware for optimal treatment. Strategies for reimplanting hardware after infection vary widely and have not previously been analyzed using a large, multicenter study. METHODS AND RESULTS The MEDIC (Multicenter Electrophysiologic Device Infection Cohort)...

Radiographic osteopenia is regularly observed after implant removal from a fracture or femoral osteotomy but has not been objectively quantified. Hardware removal is generally performed months to years after the index event (fracture or osteotomy) when full activity has been resumed. Objectively demonstrable bone mineral deficiency affects fracture risk. Hardware removal may facilitate the retu...
