    Abstract AbstractFourteen species of the genus Epidendrum , recently collected in the Área de Conservación Privada La Pampa del Burro (ACPPB), five of them new to science (Epidendrum echinatiantherum sp. nov., E. imazaense sp. nov., E. parvireflexilobum sp. nov., E. rosulatum sp. nov., and E. ochrostachyum sp. nov.), are described and illustrated. The other species include a new record for Peru (E. acrobatesii) and four for the department of Amazonas (E. brachyblastum, E. forcipatum, E. mavrodactylon, and E. tridens). Epidendrum enantilobum is here considered a synonym of Epidendrum brachyblastum. The type locality of Epidendrum cryptorhachis, originally stated as Ecuador, Guayabamba, is corrected to indicate that it refers to the valley of Guayabamba, Rodríguez de Mendoza, Amazonas, Peru. Our results show the need to continue conducting botanical exploration in the ACPPB as a baseline for subsequent studies, including a full inventory of the orchid diversity.

    Abstract The main goal in task planning is to build a sequence of actions that takes an agent from an initial state to a goal state. In robotics, this is particularly difficult because actions usually have several possible results, and sensors are prone to produce measurements with error. Partially observable Markov decision processes (POMDPs) are commonly employed, thanks to their capacity to model the uncertainty of actions that modify and monitor the state of a system. However, since solving a POMDP is computationally expensive, their usage becomes prohibitive for most robotic applications. In this paper, we propose a task planning architecture for service robotics. In the context of service robot design, we present a scheme to encode knowledge about the robot and its environment, that promotes the modularity and reuse of information. Also, we introduce a new recursive definition of a POMDP that enables our architecture to autonomously build a hierarchy of POMDPs, so that it can be used to generate and execute plans that solve the task at hand. Experimental results show that, in comparison to baseline methods, by following a recursive hierarchical approach the architecture is able to significantly reduce the planning time, while maintaining (or even improving) the robustness under several scenarios that vary in uncertainty and size.

    Abstract Purpose: Study results indicating that non-clinically significant alerts generated by clinical support systems can be reduced by recategorizing alert severity levels, thereby decreasing alert fatigue, are presented.
    Methods: In a single-site retrospective pre-post study, all drug-drug interaction alerts displayed by a medical center's clinical support system over a three-month baseline period were evaluated by a multidisciplinary expert panel. Based on a review of pharmaceutical package inserts and other evidence, the panel reduced the severity ranking of 99 of the 201 most frequently triggered alerts with the aim of reducing nonactionable alerts (i.e., alerts viewed but not resulting in a clinical intervention such as the discontinuation of a medication, a dose reduction, or the ordering of a laboratory test). Alert frequencies and types during the baseline period and a one-month period after adjustment of the alert severity rankings were compared to characterize the distribution of alert override responses.
    Results: Comparison of drug-drug interaction alerts before (n = 8023) and after (n = 7270) alert recategorization indicated significant differences in pharmacists' documentation of override responses in four evaluated categories (p < 0.001 for all comparisons); notably, alerts overrides in the "not clinically significant" category declined 22%. No significant difference was detected in the numbers of reported medication errors related to clinically significant drug-drug interaction alerts before and after alert recategorization.
    Conclusion: Reducing the number of nonactionable drug-drug interaction alerts by recategorizing alert severity levels decreased alert overrides by 6%.

    Abstract In this paper we describe the static topological fracture structure of five rock samples from three regions in Eastern Mexico by the application of centrality and communicability measures used in the area of complex networks. The information obtained from fracture images is used to characterize the fracture networks. The analysis is divided into two groups of characteristics. The first provides a general summary of the fracture network through the description of the number of nodes, edges, diameter, radius, lengths and clustering coefficients. A second group of features centers on the description of communicability in the network by means of three indexes recently proposed. In addition, we apply centrality measures (betweenness, closeness, eigenvector and eccentricity) for quantifying the importance of nodes in the entire network. Finally, we identify a topology for fracture networks using a classification based on the degree of communicability. The most important results obtained in this work are focused in the topological characteristic patterns found in fracture networks applying the approach of complex networks that in general provide local and global parameters of connectivity and communicability.
