Reversible image watermarking enables the embedding of copyright or useful information in a host image without any loss of information. Here a novel technique to improve the embedding capacity i.e. reversible watermarking using an adaptive prediction error expansion & pixel selection is proposed. This work is an improvement in conventional Prediction Error Expansion by adding two new techniques...

BACKGROUND Psychotic symptoms have been linked to religious experience, but empirical evidence is scarce. We have investigated the impact of the Welsh religious revival (RR) of 1904-1905 on the number of admissions to the regional psychiatric hospital, their diagnostic features and lifelong course. METHOD All case-notes of patients admitted to the North Wales Hospital between 1902 and 1907 we...

INTRODUCTION Fetal movement counting is a method used by mother to quantify her baby's movements. However, the optimal number of movements and the ideal duration of counting them have not been recognized. The aim of this study was to determine the diagnostic value of the two common fetal movements counting methods by mother including "ten fetal movements counting in two hours" and "three fetal ...

This study was conducted to determine the content of infection control (IC) curricula, the extent of IC monitoring and compliance, and the number of bloodborne pathogen (BBP) exposures/year in U.S. dental schools. A questionnaire was emailed to persons responsible for predoctoral IC programs. The response rate was 60 percent. Most schools did not have an independent course and used classroom le...

OBJECTIVE Body mass index (BMI) and intelligence quotient (IQ) are associated. We examined whether this association varied by birth cohort. METHODS Among 37,414 Danish conscripts, the association between BMI and IQ overall and by birth cohort was examined. IQ was measured by the Børge Prien's Prøve (BPP) group intelligence test score. RESULTS Compared with men of normal BMI, mean difference...

For relativized arguments, we propose to restrict oracle queries to “stringent” ones; for comparing the power of two machine models relative to some oracle set, stringent relativization is to restrict machines of both types to ask queries on the same segment of the oracle. In particular, for investigating polynomial-time (or polynomial-size) computability, we propose polynomial stringency, boun...

In the paper ” Relations between capacity utilization and minimal bin number“[HS12] the following two-dimensional bin packing problem (BPP) is considered: given a set K of rectangular items of sizes li × wi and bins of size L×W . Rotation of the items is not permitted. It is shown, if every item fits into the given bin and if the total area of the items does not exceed the area of the bin then ...

In this paper we give arguments both for and against the existence of an oracle A, relative to which BPP equals probabilistic linear time. First, we prove a structure theorem for probabilistic oracle machines, which says that either we can x the output of the machine by setting the answer to only polynomially many oracle strings, or else we can set part of the oracle such that the machine becom...

The birth-preparedness package (BPP) promotes active preparation and decision-making for births, including pregnancy/postpartum periods, by pregnant women and their families. This paper describes a district-wide field trial of the BPP implemented through the government health system in Siraha, Nepal, during 2003-2004. The aim of the field trial was to determine the effectiveness of the BPP to p...

A recent paper by Jančar (presented at LiCS 2003) demonstrated that bisimilarity on Basic Parallel Processes (BPP) can be decided in polynomial space. Here we explore a (more detailed) version of the respective algorithm when applied to the subclass called normed BPP (nBPP), and show that in this case the algorithm runs in polynomial time; we provide a complexity analysis yielding the upper bou...
