The weak form of the Efficient Market Hypothesis (EMH) states that the current market price fully reflects the information of past prices and rules out predictions based on price data alone. In an efficient market, consistent prediction of the next outcome of a financial time series is problematic because there are no reoccurring patterns that can be used for a reliable prediction. This researc...

We show that the maximin average redundancy in pattern coding is eventually larger than 1.84 ( n logn )1/3 for messages of length n. This improves recent results on pattern redundancy, although it does not fill the gap between known lowerand upper-bounds. The pattern of a string is obtained by replacing each symbol by the index of its first occurrence. The problem of pattern coding is of intere...

A simple design method is proposed for square root domain filters. The method is based on the imitation of passive filters (or their signal flow graphs). This allows square root domain topologies and parameters to be easily extracted. The method is augmented by a simple method to study and manipulate the filter’s DC point. The method is used to design a universal biquad filter as a demonstratio...

Laser-based refractive index detection, based upon refractive index changes in micro-channels, is a kind of laser-based optical determination for solutions. As it is capable of label-free determination, it has been regarded as a considerable growth prospect. The key aspect in related researches lay in the development of novel detection configurations, which would possibly result in better sensi...

background and objectives: urinary tract infection (uti) is one of the most common infections and a major cause of patient morbidity world wide. the gold standard for detection of bacterial pathogens in uti is culture of urine specimens. in order to facilitate identification of bacterial pathogens in clinical urine specimens we designed a molecular method to detect bacterial pathogen in uti. ma...

This paper deals with a coding problem called complementary delivery, where messages from two correlated sources are jointly encoded and each decoder reproduces one of two messages using the other message as the side information. Both lossless and lossy universal complementary delivery coding schemes are investigated. In the lossless case, it is demonstrated that a universal complementary deliv...

We consider an opportunistic communication system consisting of multiple independent channels with time-varying states. With limited sensing, a user can only sense and access a subset of channels and accrue rewards determined by the states of the sensed channels. We formulate the problem of optimal sequential channel selection as a restless multi-armed bandit process. We establish the indexabil...

BACKGROUND A consensus definition for periprocedural myocardial infarction (MI) in coronary stent trials has not been established. Differences between a historic definition, based on modified World Health Organization (WHO) criteria, and a proposed universal definition have not been compared in a prospective clinical trial. METHODS AND RESULTS We randomly assigned 3687 patients with stable co...

OBJECTIVE To compare two summary indicators for monitoring universal coverage of reproductive, maternal, newborn and child health care. METHODS Using our experience of the Countdown to 2015 initiative, we describe the characteristics of the composite coverage index (a weighted average of eight preventive and curative interventions along the continuum of care) and co-coverage index (a cumulati...

Consider a Gaussian memoryless multiple source with m components with joint probability distribution known only to lie in a given class of distributions. A subset of k ≤ m components are sampled and compressed with the objective of reconstructing all the m components within a specified level of distortion under a meansquared error criterion. In Bayesian and nonBayesian settings, the notion of u...
