We present sequential and parallel algorithms for Frontier A* (FA*) algorithm augmented with a form of Delayed Duplicate Detection (DDD). The sequential algorithm, FA*-DDD, overcomes the leak-back problem associated with the combination of FA* and DDD. The parallel algorithm, PFA*-DDD, is a parallel version of FA*-DDD that features a novel workload distribution strategy based on intervals. We o...

Globally, 1.2 million people die and 50 million people are injured annually due to traffic accidents. These traffic accidents cost $500 billion dollars. Drunk drivers are found in 40% of the traffic crashes. Existing drunk driving detection (DDD) systems do not provide accurate detection and pre-warning concurrently. Electrocardiogram (ECG) is a proven biosignal that accurately and simultaneous...

AIMS We aimed to investigate whether biventricular (BiV) pacing minimizes left ventricular (LV) dyssynchrony and preserves LV ejection fraction (LVEF) as compared with standard dual-chamber DDD(R) pacing in consecutive patients with high-grade atrio-ventricular (AV) block. METHODS AND RESULTS Fifty patients were randomized to DDD(R) pacing or BiV pacing. LVEF was measured using three-dimensio...

Materials science simulations are among the leading applications for scientific supercomputing. Discrete dislocation dynamics (DDD) is a numerical tool used to model the plastic behavior of crystalline materials using the elastic theory of dislocations. DDD simulations require very long running times to produce meaningful scientific results. This work presents early experiences and results on i...

We examine whether firms that emphasize decision making based on data and business analytics (“data driven decision making” or DDD) show higher performance. Using detailed survey data on the business practices and information technology investments of 179 large publicly traded firms, we find that firms that adopt DDD have output and productivity that is 56% higher than what would be expected gi...

In this paper, we propose a new parallel analysis method for large analog circuits using determinant decision diagram (DDD) based graph technique. DDD-based symbolic analysis technique enables exact symbolic analysis of vary large analog circuits. Once the circuit small-signal characteristics are presented by DDDs, evaluation of DDDs will give exact numerical values. In this paper, we develop e...

Abstract Background To describe intensive care unit (ICU) antibiotic use in different administrative categories based on data reported to the Nosocomial Surveillance System of State Health Department (SHD) Sao Paulo. Methods This ecological study describes at an aggregated level adult ICU São Paulo SHD, from 2009 2018. ICUs were categorized by hospital category (private, public, and philanthrop...

A novel hierarchical approach is proposed to symbolic analysis of large analog circuits. The key idea is to use a graph-based representation—called Determinant Decision Diagram (DDD)— to represent the symbolic determinant and cofactors associated with the MNA matrix for each subcircuit block. By exploiting the inherent sharing and sparsity of symbolic expressions, DDD is capable of representing...

In this clinical study, pre- and post-rehabilitation changes in intraborder mandible movements, chewing cycles, masticatory efficiencies, and borders of the chewing area of patients with unilateral muscular disorders (MD) (n = 20) or unilateral disc derangement disorders (DDD) (n = 20) of temporomandibular disorder (TMD) were observed and compared with healthy individuals with full dentition (n...
