Differential epipolar constraint in mobile robot egomotion estimation

The estimation of camera egomotion is a well established problem in computer vision. Many approaches have been proposed based on both the discrete and the differential epipolar constraint. The discrete case is mainly used in self-calibrated stereoscopic systems, whereas the differential case deals with a unique moving camera. The article surveys several methods for mobile robot egomotion estimation covering more than 0.5 million samples using synthetic data. Results from real data are also given

Do labour mobility and networks foster geographical knowledge diffusion? The case of European regions

The goal of this paper is twofold: first, we aim to assess the role played by inventors’ cross-regional mobility and networks of collaboration in fostering knowledge diffusion across regions and subsequent innovation. Second, we intend to evaluate the feasibility of using mobility and networks information to build cross-regional interaction matrices to be used within the spatial econometrics toolbox. To do so, we depart from a knowledge production function where regional innovation intensity is a function not only of the own regional innovation inputs but also external accessible R&D gained through interregional interactions. Differently from much of the previous literature, cross-section gravity models of mobility and networks are estimated to use the fitted values to build our ‘spatial’ weights matrices, which characterize the intensity of knowledge interactions across a panel of 269 regions covering most European countries over 6 years.

Educational attainment in the OECD, 1960-2010

La ramaderia extensiva a la Vall d'Alinyà. Un retrat de la ramaderia de muntanya del segle XXI

El projecte se centra en el la vall d’Alinyà, en els terrenys de la Fundació Territori i Paisatge que abasten des dels cims del Port del Comte, a més de 2.000 m d’altitud fins més avall del nucli de Perles en els 500 m, en un ambient de muntanya a la comarca de l’Alt Urgell, Catalunya. L’objectiu principal ha estat diagnosticar la situació de la ramaderia extensiva de la vall, tot predient la seva viabilitat socioeconòmica com a estratègia de futur, tant pel que fa la seva població, com per les característiques d’un paisatge en mosaic molt ben afaiçonat per la mà humana en el passat. Aquesta diversitat paisatgística assegurada per l’existència de la ramaderia extensiva, provoca una riquesa en biodiversitat ecològica, en front del creixement continu de la massa forestal causat per l’abandonament de les activitats a la muntanya. Un dels aspectes estudiats de la ramaderia de la vall, ha estat la gestió dels cinc ramats existents en l’actualitat, dos de vaques, un de cabres, un d’ovelles i un de cavalls. Des de la identificació dels moviments de transtermitància durant les diferents estacions de l’any, a la de l’obtenció dels diferents recursos alimentaris pel bestiar provinents directament de la natura. Les entrevistes personals als ramaders han estat una important font d’informació i de tractament de dades per poder diagnosticar la situació actual del sector i de la figura del pastor com a figura professional clau en la vessant socioeconòmica i paisatgística local. Es van poder identificar clarament els problemes amb els quals es troba la ramaderia extensiva i quins reptes presenta per poder arribar a ser un sector de futur per a la població de la vall. En aquest context es proposen mesures de millora de l’activitat i de difusió dels productes agroramaders de qualitat.

Producción y Productividad Agrícolas en la Isla de Mallorca, 1590-1860

This paper proposes a detailed measurement of the agricultural development of the island of Majorca from the late sixteenth century to the midnineteenth century, with an emphasis on the products which made up the bulk of the island’s agricultural production. The authors have organized most of the existing databases in the island’s archives and have also incorporated quantitative and qualitative material from their own research and that of other colleagues. Due to their quality and regularity, the data are among the richest known for pre-industrial Europe. These sources lead to some conclusions which link with recent debates in European economic history concerning the calculation of economic growth in economies for periods before statistics were kept. The text presents a methodological analysis covering almost 80 per cent of agricultural production of the island of Majorca and leaves conclusions to be supplemented by further studies of the manufacturing and service sectors

Origen i diversificació de les comunitats de rèptils dels deserts del Nord d’Àfrica i Aràbia: els paràsits com a eines filogenètiques

Els deserts constitueixen aproximadament un terç de la superfície terrestre i estan caracteritzats per la seva aridesa extrema. Els Sàhara, la zona àrida més gran del Nord d’Àfrica és, amb diferencia, el desert més gran del mon. Ocupa una extensió de més de 9 milions de kilòmetres quadrats, expandint-se 5500 km a través del nord d’Àfrica, des de l’oceà Atlàntic fins el mar Roig. El desert d’Aràbia es troba a l’est del Sàhara i és aproximadament una octava part més petit. Tot i el seu clima tan extrem, les flores i faunes dels deserts acostumen a ser relativament riques, el que fa que ens preguntem com aquestes biotes han estat adquirides i com es mantenen. En aquest projecte utilitzem els rèptils com a model d’estudi, un dels habitants més comuns dels deserts. El propòsit d’aquest projecte era utilitzar filogènies moleculars de diversos taxons de rèptils dels deserts del nord d’Àfrica i Aràbia per respondre Quan i Com els deserts han adquirit la seva fauna de rèptils endèmica (origen i diversificació), i de quina manera aquestes faunes s’han mantingut fins ara (adaptació). Però més enllà de les dades morfològiques i les eines de filogènia molecular, els paràsits representen una alternativa excitant i innovadora dins del camp de la biologia evolutiva. En aquest sentit, aquest projecte de beca proposava anar més lluny i utilitzar els paràsits com a eina (biological tags) per millor entendre l’historia evolutiva dels seus hostes en base a una aproximació biogeogràfica i co-evolutiva. Els objectius durant aquest primer any de projecte han sigut: 1) Estudiar l’origen i diversificació de la fauna de rèptils endèmica dels deserts del Sàhara i Aràbia, 2) caracteritzar la comunitat d’ecto- haemoparàsits de les espècies d’estudi, 3) posar a punt un estudi comparatiu de la filogeografia i estructuració genètica d’hostes i paràsits.

Association of NTRK3 and its interaction with NGF suggest an altered cross-regulation of the neurotrophin signaling pathway in eating disorders

Eating disorders (EDs) are complex psychiatric diseases that include anorexia nervosa and bulimia nervosa, and have higher than 50% heritability. Previous studies have found association of BDNF and NTRK2 to ED, while animal models suggest that other neurotrophin genes might also be involved in eating behavior. We have performed a family-based association study with 151 TagSNPs covering 10 neurotrophin signaling genes: NGFB, BDNF, NTRK1, NGFR/p75, NTF4/5, NTRK2, NTF3, NTRK3, CNTF and CNTFR in 371 ED trios of Spanish, French and German origin. Besides several nominal associations, we found a strong significant association after correcting for multiple testing (P = 1.04 × 10−4) between ED and rs7180942, located in the NTRK3 gene, which followed an overdominant model of inheritance. Interestingly, HapMap unrelated individuals carrying the rs7180942 risk genotypes for ED showed higher levels of expression of NTRK3 in lymphoblastoid cell lines. Furthermore, higher expression of the orthologous murine Ntrk3 gene was also detected in the hypothalamus of the anx/anx mouse model of anorexia. Finally, variants in NGFB gene appear to modify the risk conferred by the NTRK3 rs7180942 risk genotypes (P = 4.0 × 10−5) showing a synergistic epistatic interaction. The reported data, in addition to the previous reported findings for BDNF and NTRK2, point neurotrophin signaling genes as key regulators of eating behavior and their altered cross-regulation as susceptibility factors for EDs.

Design and evaluation of a panel os single-nucleotide polymorphisms in microRNA genomic regions for association studies in human disease

MicroRNAs (miRNA) are recognized posttranscriptional gene repressors involved in the control of almost every biological process. Allelic variants in these regions may be an important source of phenotypic diversity and contribute to disease susceptibility. We analyzed the genomic organization of 325 human miRNAs (release 7.1, miRBase) to construct a panel of 768 single-nucleotide polymorphisms (SNPs) covering approximately 1 Mb of genomic DNA, including 131 isolated miRNAs (40%) and 194 miRNAs arranged in 48 miRNA clusters, as well as their 5-kb flanking regions. Of these miRNAs, 37% were inside known protein-coding genes, which were significantly associated with biological functions regarding neurological, psychological or nutritional disorders. SNP coverage analysis revealed a lower SNP density in miRNAs compared with the average of the genome, with only 24 SNPs located in the 325 miRNAs studied. Further genotyping of 340 unrelated Spanish individuals showed that more than half of the SNPs in miRNAs were either rare or monomorphic, in agreement with the reported selective constraint on human miRNAs. A comparison of the minor allele frequencies between Spanish and HapMap population samples confirmed the applicability of this SNP panel to the study of complex disorders among the Spanish population, and revealed two miRNA regions, hsa-mir-26a-2 in the CTDSP2 gene and hsa-mir-128-1 in the R3HDM1 gene, showing geographical allelic frequency variation among the four HapMap populations, probably because of differences in natural selection. The designed miRNA SNP panel could help to identify still hidden links between miRNAs and human disease.

New Trends in Public Facility Location Modeling

The past four decades have witnessed an explosive growth in the field of networkbased facility location modeling. This is not at all surprising since location policy is one of the most profitable areas of applied systems analysis in regional science and ample theoretical and applied challenges are offered. Location-allocation models seek the location of facilities and/or services (e.g., schools, hospitals, and warehouses) so as to optimize one or several objectives generally related to the efficiency of the system or to the allocation of resources. This paper concerns the location of facilities or services in discrete space or networks, that are related to the public sector, such as emergency services (ambulances, fire stations, and police units), school systems and postal facilities. The paper is structured as follows: first, we will focus on public facility location models that use some type of coverage criterion, with special emphasis in emergency services. The second section will examine models based on the P-Median problem and some of the issues faced by planners when implementing this formulation in real world locational decisions. Finally, the last section will examine new trends in public sector facility location modeling.

Bargaining, coalitions and competition

We study a decentralized matching model in a large exchange economy,in which trade takes place through non--cooperative bargaining in coalitionsof finite size. Under essentially the same conditions of core equivalence, we show that the strategic equilibrium outcomes of our model coincide with theWalrasian allocations of the economy. Our method of proof exploits equivalenceresults between the core and Walrasian equilibria. Our model relaxes differentiability and convexity of preferences thereby covering the caseof indivisible goods.

The impact of trade liberalization on skill upgrading. Evidence from Argentina

In this paper I study the effects of a regional free trade agreement on the demand for skill.I start by documenting a series of facts to shed light on the determinants of a steep increasein the relative demand of skilled labor in a panel of Argentinean industrial firms covering thetrade liberalization period. First, this is not explained by labor reallocation across industriesor firms but by skill upgrading within firms. Second, exporters upgrade skill faster than nonexporters. Third, firms upgrading skill also upgrade technology. These findings are consistentwith a model where a reduction in trading partner s tariffs induces the most productive firms(exporters) to adopt skill-intensive production technologies. Indeed, I find that the reduction inBrazil s tariffs induces the most productive Argentinean firms to upgrade skill, while the leastproductive ones downgrade. One third of the increase in the relative demand for skill can beattributed to the reduction in Brazil s tariffs.

On prediction of individual sequences

Sequential randomized prediction of an arbitrary binary sequence isinvestigated. No assumption is made on the mechanism of generating the bit sequence. The goal of the predictor is to minimize its relative loss, i.e., to make (almost) as few mistakes as the best ``expert'' in a fixed, possibly infinite, set of experts. We point out a surprising connection between this prediction problem and empirical process theory. First, in the special case of static (memoryless) experts, we completely characterize the minimax relative loss in terms of the maximum of an associated Rademacher process. Then we show general upper and lower bounds on the minimaxrelative loss in terms of the geometry of the class of experts. As main examples, we determine the exact order of magnitude of the minimax relative loss for the class of autoregressive linear predictors and for the class of Markov experts.
