We present a mathematical physics analysis of entangled translucent eavesdropping in quantum cryptography, based on the recent work of Ekert, Huttner, Palma, and Peres @Phys. Rev. A 50, 1047 ~1994!#. The key generation procedure involves the transmission, interception, and reception of two nonorthogonal photon polarization states. At the receiving end, a positive operator valued measure ~POVM! ...

A combined source/channel coding scheme without explicit error protection is proposed to transmit images through binary noisy channels. Unlike the error protection with re-transmission scheme and error concealment scheme by inserting synchronization codewords to entropy-coded bitstream, the proposed coding scheme employs transform coding, "xed-rate uniform threshold trellis coded quantization (...

Serial results from an individual are often obtained using more than one method. Results should be transferable over time and locale. Every method has inherent analytical error, and goals are required to delineate the maximum allowable random (imprecision) and systematic (inaccuracy, bias) errors to facilitate optimal patient care. Based on Harris's proposal [Am J Clin Pathol 1979;72:374-82] th...

This paper studies distributed networked systems with data dropouts and transmission delays. We propose a decentralized eventtriggering scheme, where a subsystem broadcasts its state information to its neighbors only when the subsystem’s local state error exceeds a specified threshold. The novelty of this scheme is its complete decentralization, which means that a subsystem’s broadcast decision...

OBJECTIVE To estimate relative expanded uncertainty measurement of routine clinical chemistry analytes for international organisation for standardisation 15189 accreditation. METHODS This cross-sectional study was conducted at Dow International Medical College, Karachi, from September 2013 to May 2014. During the process of international organisation for standardisation 15189 accreditation, m...

Presented are the investigations showing an impact of the length of data signals in hardware implemented Kohonen Self-Organizing Maps (SOM) on the quality of the learning process. The aim of this work was to determine the allowable reduction of the number of bits in particular signals that does not deteriorate the network behavior. The efficiency of the learning process has been quantified by u...

Current U.S. governmental regulations and requirements for the quality of laboratory tests do not provide a consistent form, comparable numbers, or practical specifications for the routine operation of laboratory testing processes. For cholesterol, as an example, the Health Care Financing Administration provides an analytical performance criterion for proficiency testing to enforce the Clinical...

Watermarking channel capacity is defined as the highest rate in bits per image of information that can be embedded with arbitrarily low probability of detection error under a given distortion between original and watermarked image. It is analogous to channel capacity defined in information theory. A mathematical method of decisionmaking called Game Theory, in which a competitive situation invol...

The maximum allowable biological concentration of a toxic substance is the highest concentration which can be found in a biological medium without damage to health. The biological materials rna y be examined for: (a) the toxic substance itself; (b) a product of the metabolism of the toxic substance in the body; (c) a substance derived from the physiopathological activity of the toxic substance;...
