Traditional heuristic search algorithms use the ranking of states that a heuristic function provides to guide the search. In this paper—with the objective of improving suboptimality and runtime of search algorithms when only weak heuristics are available—we present Stratified Tree Search (STS), a suboptimal heuristic search algorithm that uses a heuristic to partition the state space to guide t...
Purpose. Patients with soft tissue sarcomas (STS) are at increased risk of second primary malignancies, including a second STS, but distinction between metastases and a second primary STS is difficult. Patients and Methods. Array-based comparative genomic hybridization (aCGH) was applied to 30 multiple STS of the extremities and the trunk wall from 13 patients. Different histotypes were present...
Burkholderia pseudomallei isolates with shared multilocus sequence types (STs) have not been isolated from different continents. We identified two STs shared between Australia and Cambodia. Whole-genome analysis revealed substantial diversity within STs, correctly identified the Asian or Australian origin, and confirmed that these shared STs were due to homoplasy.
A Socio-Technical System (STS) is an interplay of humans, organizations and technical systems. STSs consist of interacting actors, which depend on one another to achieve their objectives. In previous work, we have proposed STS-ml, a security requirements modelling language (using i*-like primitives such as actor, goal, delegation) for the design of secure STSs. STS-ml represents security requir...
OBJECTIVE To develop a customized short LOS (<6 days) prediction model for geriatric patients receiving cardiac surgery, using local data and a computational feature selection algorithm. DESIGN Utilization of a machine learning algorithm in a prospectively collected STS database consisting of patients who received cardiac surgery between January 2002 and June 2011. SETTING Urban tertiary-ca...
derivative of tanshinone IIa, which is the main lipophilic component contained in Salvia miltiorrhiza known as ‘Danshen’ in traditional Chinese medicine. The pharmacological activity of STS is due to tanshinone IIA, which is a cardioprotective substance and may exert a beneficial effect on the clinically important vascular endothelium. The use of tanshinone IIA is limited by its poor water solu...
Much is known about the sit-to-stand (STS) and its biomechanics. Currently, however, there is little opportunity for instrumented quantification of the STS as part of screening or diagnosis in clinical practice. The objectives of the present study were to describe the feasibility of using an automated approach for quantifying the STS using one sensor location and to start testing the discrimina...
STS (soft tissue sarcomas) are rare malignant tumours deriving from cells of mesenchymal origin and represent only 1% of all malignant neoplasms. It has been extensively demonstrated that angiogenesis has an important role in cancer malignancy. Particularly, a lot of studies demonstrate the importance of angiogenesis in the development of carcinomas, whereas little is known about the role of an...
