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...

Traditionally, symmetric-key message authentication codes (MACs) are easily built from pseudorandom functions (PRFs). In this work we propose a wide variety of other approaches to building efficient MACs, without going through a PRF first. In particular, unlike deterministic PRF-based MACs, where each message has a unique valid tag, we give a number of probabilistic MAC constructions from vario...

[Purpose] The aim of this study was to evaluate the relationships among vision problems, developmental levels, upper extremity functions, and qualities of life of children with cerebral palsy (CP). [Subjects] The study included 32 children, aged 4-15 years, diagnosed with diplegic type CP. [Methods] Hand function was evaluated using the Manual Ability Classification System (MACS) and the Bimanu...
