Abstract
This paper reports the participation of the InfoLab at the TREC Precision Medicine Track 2018. InfoLab is an informal group that brings together researchers with interest in the information area and is located at Faculty of Engineering of University of Porto. The experiments made in this participation include query expansion approaches for the disease and gene concepts. The expansion of the disease terms was done using Unified Medical Language System (UMLS). UMLS is a repository that provides the mapping between a large number of vocabularies. The gene terms were expanded using Ensembl. Ensembl provides a genome browser that maps genes to their synonyms. An additional layer was developed on top of Terrier to provide the execution of a large batch of experiments. Multiple runs were evaluated in order to measure the influence of each expansion approach.

Abstract
We analyze the relationship between cultural values, societal values and the type of the economy with necessity-driven, opportunity-driven and improvement-driven entrepreneurship. We take into account GEM's data from 56 countries. These reports are also used to characterize the three types of entrepreneurship, the societal values and the type of economy. We approach national culture through the five dimensions of Hofstede's work on cultural values using the Values Survey Module 2013 (based on Hofstede's work). Cultural values marginally explain necessity-driven and opportunity-driven entrepreneurship. In turn, societal values only explain improvement-driven entrepreneurship. Finally, the type of economy is important in explaining necessity-driven and opportunity-driven entrepreneurship, however it is of no added value in explaining improvement-driven opportunity. One needs to be cautious when drawing general conclusions as we believe that societal values are failing to capture differences among the types of entrepreneurship analyzed.

Abstract
Distributed energy resources (DERs) can provide a number of functions to be used in grid services with proper establishment of control and communication systems. However, there are neither general standards for vendor independent integration of these assets in management activities, nor common consideration of specific flexibilities that different DERs have. This paper investigates characterization and comparison of individual power and energy management flexibilities of different types of distributed energy resources. Emerging DER capability identification approaches are used to highlight contrasting differences between several energy storage and distributed generation options. Experiments were conducted in a low voltage test facility to compare flexibility limits using the same control and communication infrastructure. © 2018 IEEE.

Abstract
3D path planning with unmanned aerial vehicles in search and rescue scenarios is an important research area, due to the ability to explore damage areas that could be inaccessible for vehicles like ground robots. This paper presents two innovative real-time path planning algorithms based on PRM (Probabilistic Road Map) able to be implemented in UAV’s denoted by Grid Path Planning Roadmap Planning (GPRM) and the Particle Probabilistic Roadmap (PPRM). With the requirement of being implemented in a real search and rescue scenario like the EuRathlon competition, the GPRM method will produce a roadmap building step with obstacles inside a predefined grid while PPRM will follow a different approach by introducing an associated probability to each computed path in order to support the next sampling step path planning iteration. Both methods were evaluated and compared with the well known 3D path planning PRM in a search and rescue earthquake simulation environment developed in MORSE (Modular Open Robots Simulation Engine). © 2018 by World Scientific Publishing Co.
