Background In clinical chemistry, a number of studies shows that the probability of very large errors is much greater than expected from the Gaussian distribution. In addition, it has been empirically found that the behavior of nonlin-ear complex systems is often asymptotically exponential. Consequently, we may assume that the error of some analytical systems may be approximated by the sum of a...

background and objective: laboratory errors are one of the major factors that affect the diagnosis, prognosis, treatment and monitoring in patients.the objective of study is to evaluate the frequency and type of errors in different phases of testing at the pathology department of the shalamar hospital, lahore and to evaluate the causes of errors. methods: this observational study was carried o...

This paper provides several error estimations for total variation (TV) type regularization, which arises in a series of areas, instance, signal and imaging processing, machine learning, etc. In this paper, some basic properties the minimizer TV regularization problem such as stability, consistency convergence rate are fully investigated. Both priori posteriori rules considered paper. Furthermor...

Clinical laboratories play a vital role in patient care, but many diagnostic errors are associated with laboratory testing. The past decades have seen sustained improvements in analytical performances but the error rates, particularly in pre- and post-analytical phases is still high. Although the seminal concept of the brain-to-brain laboratory loop has been described more than four decades ago...

Analytical expressions for the symbol (SER) and bit error (BER) rates are presented for quadrature phase shift keying (QPSK) modulated orthogonal frequency division multiplexing (OFDM) systems in the presence of multiple narrowband interferers (NBIs). The analytical expressions can be used for additive white Gaussian noise (AWGN) channels, and flat& frequencyselective fading channels. These ana...
