disease (AD) at the earliest stages, the answer might be right in the eyes. An eye scan may allow early detection of AD, opening the possibility of earlier and more effective treatment intervention. A recent study at Cedars-Sinai provides the fi rst evidence of amyloid plaques (the hallmark pathological signs of AD) in the retinas of deceased patients, including retinas of those who were probab...

In 2004, Abe et al. proposed a threshold signer-ambiguous signature scheme from variety of keys. Their scheme is a generalized case of the ring signature scheme, and it allows the key types to be based on the trapdoor one-way permutations (TOWP) or sigma-protocols including Schnorr’s signature scheme. However, the signed message is public for all, which may result in disputes. In this paper, we...

The European Union Emissions Trading System (EU ETS), presented as the “flagship” of European climate policy, is subject to many criticisms from different stakeholders: it does not reduce carbon emissions nor generate enough low-carbon innovation, it induces competitiveness losses and carbon leakage, its distributional effects are unfair and finally, it is susceptible to fraud. We review these ...

Sparse direct solvers, and in particular multifrontal methods, are widely used in various simulation problems. Because of their large memory requirements, the use of out-of-core solvers is compulsory for large-scale problems, where disks are used to extend the core memory. This study is at the junction of two previous independent works: it extends the problem of the minimization of the volume o...

A wide area monitoring system (WAMS) with reliable telecommunication infrastructure can be expanded and enhanced with additional protection and control functionalities using synchronized phasor data measurements. With that aim, we have developed a multifunctional line protection (MFLP) model with both system and back-up protection functions. Theoretical premises based on transmission and relay ...

Thehealthcare services are among the fastest growing service markets deploying wireless technologies. As healthcare organizations continue to become more distributed, mobile handheld devices and their associated support has evolved into a viable platform for these organizations. However, one factor that hinders the deployment of the handheld technology is the lack of support for exception handl...

Mutual exclusion is a well-known problem that arise when multiple processes compete, in an uncoordinated way, for the acquisition of shared resources over a distributed system. In particular, k-mutual exclusion allows at most k processes to get one unit of the same resource simultaneously. These paradigms do not cover all the cases in which resource accesses must be serialized over a distribute...

A numerical finite difference study has been earned out for two dimensional radiation-natural convection interaction phenomena in a vertical circular pin located at a non-participating (i.e. transparent) fluid. The coupled conservation equations in boundary layer (continuity, momentum, and energy equations) and pin energy equation are solved simultaneously using modified box method and fully im...

A completely general method of analysis for three-dimensional raked piles under harmonic excitation is discussed. The piles have been represented by a three-dimensional frame structure and the soil has been represented by a boundary element discretization scheme. A computer program has been written which carries out this analysis and produces a group stiffness matrix that can be included as a f...

While several potential auditory cues responsible for sound source externalization have been identified, less work has gone into providing a simple and robust way of manipulating perceived externalization. The current work describes a simple approach for parametrically modifying individualized head-related transfer function spectra that results in a systematic change in the perceived externaliz...
