Landscape metrics and indices : an overview of their use in landscape research

The aim of this overview paper is to analyze the use of various landscape metrics and landscape indices for the characterization of landscape structure and various processes at both landscape and ecosystem level. We analyzed the appearance of the terms landscape metrics/indexes/indices in combination with seven main categories in the field of landscape ecology [1) use/selection and misuse of metrics, 2) biodiversity and habitat analysis; 3) water quality; 4) evaluation of the landscape pattern and its change; 5) urban landscape pattern, road network; 6) aesthetics of landscape; 7) management, planning and monitoring] in the titles, abstracts and/or key words of research papers published in international peer-reviewed scientific journals indexed by the Institute of Science Information (ISI) Web of Science (WoS) from 1994 to October 2008. Most of the landscape metrics and indices are used concerning biodiversity and habitat analysis, and also the evaluation of landscape pattern and its change (up to 25 articles per year). There are only a few articles on the relationships of landscape metrics/indices/indexes to social aspects and landscape perception

BCI-assisted training for upper limb motor rehabilitation: estimation of effects on individual brain connectivity and motor functions

The aim of the study is to quantify individual changes in scalp connectivity patterns associated to the affected hand movement in stroke patients after a 1-month training based on BCIsupported motor imagery to improve upper limb motor recovery. To perform the statistical evaluation between pre- and post-training conditions at the single subject level, a resampling approach was applied to EEG datasets acquired from 12 stroke patients during the execution of a motor task with the stroke affected hand before and after the rehabilitative intervention. Significant patterns of the network reinforced after the training were extracted and a significant correlation was found between indices related to the reinforced pattern and the clinical outcome indicated by clinical scales

Financial Integration of Stock Markets among New EU Member States and the Euro Area

The paper considers the empirical dimension of financial integration among stock markets in four new European Union member states (the Czech Republic, Hungary, Poland and Slovakia) in comparison with the euro area. The main objective is to test for the existence and determine the degree of the four states’ financial integration relative to the euro currency union. The analysis is performed at the country level (using national stock exchange indices) and at the sectoral level (considering banking, chemical, electricity and telecommunication indices). Our empirical evaluation consists of (1) an analysis of alignment (by means of standard and rolling correlation analysis) to outline the overall pattern of integration; (2) the application of the concept of beta convergence (through the use of time series, panel and state-space techniques) to identify the speed of integration; and (3) the application of so-called sigma convergence to measure the degree of integration. We find evidence of stock market integration on both the national and sectoral levels between the Czech Republic, Hungary, Poland and the euro area.Beta convergence, new EU member states, sigma convergence, stock markets.

Financial Integration of Stock Markets among New EU Member States and the Euro Area

The paper considers the empirical dimension of financial integration among stock-exchange markets in four new European Union member states (Czech Republic, Hungary, Poland, and Slovakia) in comparison with the euro area. The main objective is to test for the existence and determine the degree of the four states’ financial integration relative to the euro currency union. The analysis is performed at the country level (using national stock-exchange indices) and at the sectoral level (considering banking, chemical, electricity, and telecommunication indices). Our empirical evaluation consists of (1) a harmonization analysis (by means of standard and rolling correlation analysis) to outline the overall pattern of integration; (2) the application of the concept of beta convergence (through the use of time series, panel, and state-space techniques) to identify the speed of integration; and (3) the application of so-called sigma convergence to measure the degree of integration. We find evidence of respective stock-market integration on both national and sectoral levels between the Czech Republic, Hungary, Poland, and the euro area.beta convergence, new EU member states, sigma convergence, stock markets

Clinical and pathological characteristics of peripheral T‐cell lymphomas in a Spanish population: a retrospective study

We investigated the clinicopathological features and prognostic factors of patients with peripheral T-cell lymphoma (PTCL) in 13 sites across Spain. Relevant clinical antecedents, CD30 expression and staining pattern, prognostic indices using the International Prognostic Index and the Intergruppo Italiano Linfomi system, treatments, and clinical outcomes were examined. A sizeable proportion of 175 patients had a history of immune-related disorders (autoimmune 16%, viral infections 17%, chemo/radiotherapy-treated carcinomas 19%). The median progression-free survival (PFS) and overall survival (OS) were 7·9 and 15·8 months, respectively. Prognostic indices influenced PFS and OS, with a higher number of adverse factors resulting in shorter survival (P 15% of cells were positive in anaplastic lymphoma kinase-positive and -negative anaplastic large-cell lymphoma and extranodal natural killer PTCL groups. We observed PTCL distribution across subtypes based on haematopathological re-evaluation. Poor prognosis, effect of specific prognostic indices, relevance of histopathological sub-classification, and response level to first-line treatment on outcomes were confirmed. Immune disorders amongst patients require further examination involving genetic studies and identification of associated immunosuppressive factors

First Class Call Stacks: Exploring Head Reduction

Weak-head normalization is inconsistent with functional extensionality in the call-by-name $\lambda$-calculus. We explore this problem from a new angle via the conflict between extensionality and effects. Leveraging ideas from work on the $\lambda$-calculus with control, we derive and justify alternative operational semantics and a sequence of abstract machines for performing head reduction. Head reduction avoids the problems with weak-head reduction and extensionality, while our operational semantics and associated abstract machines show us how to retain weak-head reduction's ease of implementation.Comment: In Proceedings WoC 2015, arXiv:1606.0583
