Quantum++: A modern C++ quantum computing library.

Quantum++ is a modern general-purpose multi-threaded quantum computing library written in C++11 and composed solely of header files. The library is not restricted to qubit systems or specific quantum information processing tasks, being capable of simulating arbitrary quantum processes. The main design factors taken in consideration were the ease of use, portability, and performance.

Identification and Prevention of Secondary Heart Failure: A Case Study.

Heart failure, a complex clinical syndrome affecting millions of Americans, is associated with high morbidity and mortality and a significant financial burden on the health care system. Recent health care reform efforts have focused on reducing 30-day heart failure hospital readmissions, increasing the cost-effectiveness of care provided to heart failure patients, and improving health outcomes for these patients. This case report describes an acutely ill patient with multiple comorbidities who was not initially admitted for heart failure but who developed acute decompensated heart failure during his hospital stay.

Nonzero Classical Discord.

Quantum discord is the quantitative difference between two alternative expressions for bipartite mutual information, given respectively in terms of two distinct definitions for the conditional entropy. By constructing a stochastic model of shared states, classical discord can be similarly defined, quantifying the presence of some stochasticity in the measurement process. Therefore, discord can generally be understood as a quantification of the system's state disturbance due to local measurements, be it quantum or classical.

Universal uncertainty relations.

Uncertainty relations are a distinctive characteristic of quantum theory that impose intrinsic limitations on the precision with which physical properties can be simultaneously determined. The modern work on uncertainty relations employs entropic measures to quantify the lack of knowledge associated with measuring noncommuting observables. However, there is no fundamental reason for using entropies as quantifiers; any functional relation that characterizes the uncertainty of the measurement outcomes defines an uncertainty relation.

Statistical association criteria in forensic psychiatry-a criminological evaluation of casuistry.

Purpose: Identification of potential shared primary psychoprophylaxis and crime prevention is measured by analyzing the rate of commitments for patients-subjects to forensic examination.

Material And Method: The statistic trial is a retrospective, document-based study. The statistical lot consists of 770 initial examination reports performed and completed during the whole year 2007, primarily analyzed in order to summarize the data within the National Institute of Forensic Medicine, Bucharest, Romania (INML), with one of the group variables being 'particularities of the psychiatric patient history', containing the items 'forensic onset', 'commitments within the last year prior to the examination' and 'absence of commitments within the last year prior to the examination'.
