Wireless sensor network (WSN) commonly requires lower level security for public information gathering, whilst body sensor network (BSN) must be secured with strong authenticity to protect personal health information. First in this paper, some practical problems with the Message Authentication Codes (MACs), which are suggested in the current security architectures for WSN, are reconsidered. The ...

Although cultured myoblast transplantation has been extensively studied as a gene complementation approach to muscular dystrophy treatment, clinical success has still been limited. The inability to adequately isolate and purify myoblasts presents a major limitation to the production of sufficient myoblasts for engrafting purposes. This study attempted to purify myoblasts from primary culture by...

OBJECTIVES/HYPOTHESIS Most cases of chronic otitis media (OMC) are associated with poor development of the mastoid air cells (MACs) and poor Eustachian tube (ET) function. We have previously reported that MAC regeneration can effectively eliminate intractable OMC. In this study, we assessed the ability of regenerated MACs to restore normal gas exchange function and contribute to improved ET fun...

INTRODUCTION  Atherosclerosis is a systemic pathological process involving the whole arterial bed. Valvular calcifications are associated with cardiovascular risk factors. Significant carotid stenosis accounts for approximately 20% of cerebrovascular ischemic episodes.  OBJECTIVES  The aim of the study was to assess the relationship between mitral and aortic annular calcifications, increased ...

This article describes the development and testing of the first automatically microfabricated probes to be used in conjunction with the magic angle coil spinning (MACS) NMR technique. NMR spectroscopy is a versatile technique for a large range of applications, but its intrinsically low sensitivity poses significant difficulties in analyzing mass- and volume-limited samples. The combination of m...

The purpose of this study was to investigate the utility of function classification system in children with cerebral palsy (CP). For this, relationship among the Manual Ability Classification System (MACS), the Gross Motor Function Classification System (GMFCS), and the functional status (WeeFIM) in children with cerebral palsy form September 2008 to August 2010. The participants was 217 childr...

Homomorphic MACs, introduced by Gennaro and Wichs in 2013, allow anyone to validate computations on authenticated data without knowledge of the secret key. Moreover, the secret-key owner can verify the validity of the computation without needing to know the original (authenticated) inputs. Beyond security, homomorphic MACs are required to produce short tags (succinctness) and to support composa...

We report state-of-the-art atomistic simulations combined with high-fidelity conductance calculations to probe structure-conductance relationships in Au-benzenedithiolate (BDT)-Au junctions under elongation. Our results demonstrate that large increases in conductance are associated with the formation of monatomic chains (MACs) of Au atoms directly connected to BDT. An analysis of the electronic...

Recent studies on directional media access protocols (MACs) using smart antennas for wireless ad hoc networks have shown that directional MACs outperform against traditional omini-directional MACs. Those studies evaluate the performance mainly on simulations, where antenna beam is assumed to be ideal, i.e., with neither side-lobes nor back-lobes. Propagation conditions are also assumed to be ma...

This paper describes Microwave Activated Combustion Synthesis (MACS) of intermetallics of technical importance in the Co-Si binary system. These materials have important electronic applications as thin films. Bulk CoSi2 is required for use as a target for the production of thin films in sputtering processes. Sputtering targets are generally processed either by a powder route, casting or mechani...
