We discuss numerical modeling attacks on several proposed strong physical unclonable functions (PUFs). Given a set of challenge-response pairs (CRPs) of a Strong PUF, the goal of our attacks is to construct a computer algorithm which behaves indistinguishably from the original PUF on almost all CRPs. If successful, this algorithm can subsequently(More)
BACKGROUND Inflammatory and immune responses triggered by brain ischemia worsen clinical outcomes of stroke and contribute to hemorrhagic transformation, massive edema, and reperfusion injury associated with intravenous alteplase. We assessed whether a combination of the immune-modulator fingolimod and alteplase is safe and effective in attenuating(More)
One part of the original PUF promise was their improved resilience against physical attack methods, such as cloning, invasive techniques, and arguably also side channels. In recent years, however, a number of effective physical attacks on PUFs have been developed [17,18,20,8,2]. This paper continues this line of research, and introduces the first power and(More)
We discuss the question of how physical statements can be proven over digital communication channels between two parties (a "prover" and a "verifier") residing in two separate local systems. Examples include: (i) "a certain object in the prover's system has temperature X°C", (ii) "two certain objects in the prover's system are positioned at distance(More)
Physical Unclonable Functions (PUFs) use random physical variations to map input challenges to output responses in a way that is unique to each chip. PUFs are promising low cost security primitives but unreliability of outputs limits the practical applications of PUFs. This work addresses two causes of unreliability: environmental noise and device aging. To(More)
BACKGROUND Administration of convalescent plasma, serum, or hyperimmune immunoglobulin may be of clinical benefit for treatment of severe acute respiratory infections (SARIs) of viral etiology. We conducted a systematic review and exploratory meta-analysis to assess the overall evidence. METHODS Healthcare databases and sources of grey literature were(More)
PURPOSE To measure laminar and peripapillary scleral architecture in normal and glaucomatous Chinese eyes with normal and those with elongated axial length. METHODS The histomorphometric investigation included a normal group (nonaxially elongated eyes) of 40 human globes (40 patients; mean age, 41.3 +/- 13.4 years; range,15-68) enucleated because of(More)
The Escherichia coli homolog of GroEL, a 60 kDa heat shock protein (HSP), is a dominant protein produced not only in response to heat stress but also under in vitro growth condition. Beside its traditional cytoplasmic location, the surface exposures of GroEL have been observed in many pathogenic bacteria. To investigate the role of the surface-associated(More)
PURPOSE Initial response of intraocular retinoblastoma to chemotherapy has encouraged primary chemotherapy instead of primary enucleation for eyes with clinical features suggesting high risk of extraocular extension or metastasis. Upfront enucleation of such high-risk eyes allows pathologic evaluation of extraocular extension, key to management with(More)
