A characterization of cooperative TU-games with large monotonic core

Cooperative TU-games with large core were introduced by Sharkey (1982) and the concept of Population Monotonic Allocation Scheme was defined by Sprumont (1990). Linking these two concepts, Moulin (1990) introduces the notion of large monotonic core giving a characterization for three-player games. In this paper we prove that all games with large monotonic core are convex. We give an effective criterion to determine whether a game has large monotonic core and, as a consequence, we obtain a characterization for the four-player case.aspiration, pmas, cooperative games, monotonic core

On the monotonic core

The monotonic core of a cooperative game with transferable utility (T.U.-game) is the set formed by all its Population Monotonic Allocation Schemes. In this paper we show that this set always coincides with the core of a certain game associated to the initial game.restricted games, cooperative games, population monotonic allocation schemes, monotonic core

Influence of childhood obesity on spatio-temporal gait parameters

Abstract The musculoskeletal and neurosensorial development of children can be affected by excess body weight. Studies have examined how childhood obesity affects gait, but much about the influence of this factor remains to be determined. The aim of our study is to analyse, in a large sample of children, the influence of obesity on the spatiotemporal parameters of the gait cycle, in the most natural way possible, with the subjects walking overground at a self-selected speed. Method. For this study, the sample was composed of 238 healthy school children, composed of 114 (47.9%) girls and 124 (52.1%) boys, aged 7 to 11 years. For each one, the body mass index was calculated, according to which the subjects were classified by percentiles as low weight, normal weight, overweight or obese. Anthropometric variables were measured and the spatiotemporal parameters of gait were assessed by the OptoGait® portable photocell system. Results. The spatial variables did not reveal significant differences between the children with normal weight and those with obesity. However, the differences for stance phase, load response and pre-swing phase (p=0.000, p=0.016 and p=0.000, respectively) were clearly significant. Conclusions. Childhood obesity exerts a significant influence on gait by increasing the duration of load response and that of the pre-swing towards the oscillation phase and therefore the total duration of the support phase. This outcome requires greater energy expenditure to stabilise the gait of children with obesity, and could have biomechanical repercussions

Diagnostic avenues in (post-transplant) lymphoproliferative disorders

The aim of this thesis was to investigate the role of imaging in the management of PTLD, with focus on [18F]FDG PET/CT. Additionally, we set out to explore new diagnostic methods with potential for clinical translation. In Part I (chapters 2-7), we reviewed the published literature on the role of different imaging modalities in PTLD and evaluated the diagnostic performance of [18F]FDG PET/CT for PTLD lesion detection in adults and children. Furthermore, we explored the role of [18F]FDG PET/CT semiquantification in PTLD for lesion classification and prognostication. In Part II (chapters 8-10) we proceeded to explore new avenues of research including: radiomics, identification of radiotracers adjunct to [18F]FDG and cfDNA analysis

Green Security Plugin for Pervasive Computing using the HADAS toolkit

Energy is a critical resource in pervasive computing devices. However, information about energy consumption is not directly accessible through software development environments, making it difficult to reuse the knowledge provided by existing energy-consumption experimental studies. To address this limitation, this paper presents a solution to enrich Android Studio with energy consumption information. We have developed a Green Security Plugin that provides energy-aware information to developers that make use of Android Security API. This plugin has been developed taking advantage of the functionalities provided by the HADAS toolkit. HADAS is a repository of energy consuming concerns in which researchers can store the energy measures obtained during their experimental studies and developers can perform a sustainability analysis to make green design/implementation decisions.Universidad de Málaga.

The custom-made foot orthosis using the Central Stabilizer Element: nex concept of element

Foot orthoses have been applied for the management of lower limb disorders, mainly for those who develop foot pain. The Central Stabilizer Element (CSE) is a new element that contains the midfoot laterally when a plantar insole is manufactured. OBJECTIVES: - To determine the effect on foot pain of adding the Central Stabilizer Element during the manufacturing process of foot orthosis, -- - To describe the proportions of Central Stabilizer Element in terms of width and length of this element. METHODS: A sample comprising 130 patients (57 males and 73 females) with foot pain was recruited for this study, with the patients having supinated, neutral, pronated and overpronated feet. All the patients received a custom-made foot orthosis with the Central Stabilizer Element. The Central Stabilizer Element was made of resins of polyvinyl chloride, and is a device insert in foot orthosis that contains the midfoot laterally to control pronation and supination movements. Conclusion •The students know how to design the insole. •They know how to match different foot posture with the different types of insoles •We make our decisions based on the scientific evidence foundUniversidad de Málaga.
