Up-regulation of somatostatin receptor density on rat CA20948 tumors escaped from low dose [(177)Lu-DOTA(0),Tyr(3)]octreotate therapy

AIM: Peptide receptor radionuclide therapy using the somatostatin analogue [(177)Lu-DOTA(0),Tyr(3)]octreotate is a convincing treatment modality for metastasized neuroendocrine tumors. Therapeutic doses are administered in 4 cycles with 6-10 week intervals. A high somatostatin receptor density on tumor cells is a prerequisite at every administration to enable effective therapy. In this study, the density of the somatostatin receptor subtype 2 (sst2) was investigated in the rat CA20948 pancreatic tumor model after low dose [(177)Lu-DOTA(0), Tyr(3)]octreotate administration resulting in approximately 20 Gy tumor radiation absorbed dose, whereas 60 Gy is needed to induce complete tumor regression in these and the majority of tumors. METHODS: Sixteen days after inoculation of the CA20948 tumor, male Lewis rats were injected with 185 MBq [(177)Lu-DOTA(0),Tyr(3)]octreotate to initiate a decline in tumor size. Approximately 40 days after injection, tumors re-grew progressively after initial response. Quantification of sst2 expression was performed using in vitro autoradiography on frozen sections of three groups: control (not-treated) tumors, tumors in regression and tumors in re-growth. Histology and proliferation were determined using HE- and anti-Ki-67-staining. RESULTS: The sst2 expression on CA20948 tumor cells decreased significantly after therapy to 5% of control level. However, tumors escaping from therapy showed an up-regulated sst2 level of 2-5 times higher sst2 density compared to control tumors. CONCLUSION: After a suboptimal therapeutic dose of [(177)Lu-DOTA(0),Tyr(3)]octreotate, escape of tumors is likely to occur. Since these cells show an up-regulated sst2 receptor density, a next therapeutic administration of radiolabelled sst2 analogue can be expected to be highly effective.

A 700-year paleoecological record of boreal ecosystem responses to climatic variation from Alaska

Recent observations and model simulations have highlighted the sensitivity of the forest - tundra ecotone to climatic forcing. In contrast, paleoecological studies have not provided evidence of tree-line fluctuations in response to Holocene climatic changes in Alaska, suggesting that the forest - tundra boundary in certain areas may be relatively stable at multicentennial to millennial time scales. We conducted a multiproxy study of sediment cores from an Alaskan lake near the altitudinal limits of key boreal-forest species. Paleoecological data were compared with independent climatic reconstructions to assess ecosystem responses of the forest - tundra boundary to Little Ice Age (LIA) climatic. uctuations. Pollen, diatom, charcoal, macrofossil, and magnetic analyses provide the first continuous record of vegetation -. re - climate interactions at decadal to centennial time scales during the past 700 years from southern Alaska. Boreal-forest diebacks characterized by declines of Picea mariana, P. glauca, and tree Betula occurred during the LIA ( AD 1500 - 1800), whereas shrubs ( Alnus viridis, Betula glandulosa/nana) and herbaceous taxa (Epilobium, Aconitum) expanded. Marked increases in charcoal abundance and changes in magnetic properties suggest increases in. re importance and soil erosion during the same period. In addition, the conspicuous reduction or disappearance of certain aquatic ( e. g., Isoetes, Nuphar, Pediastrum) and wetland ( Sphagnum) plants and major shifts in diatom assemblages suggest pronounced lake-level. uctuations and rapid ecosystem reorganization in response to LIA climatic deterioration. Our results imply that temperature shifts of 1 - 2 degrees C, when accompanied by major changes in moisture balance, can greatly alter high-altitudinal terrestrial, wetland, and aquatic ecosystems, including conversion between boreal-forest tree line and tundra. The climatic and ecosystem variations in our study area appear to be coherent with changes in solar irradiance, suggesting that changes in solar activity contributed to the environmental instability of the past 700 years.

Trajectory of posttraumatic stress disorder caused by myocardial infarction: a two-year follow-up study

OBJECTIVE: A substantial proportion of patients develop posttraumatic stress disorder (PTSD) following myocardial infarction (MI). Previous research on the trajectory over time of PTSD in post-MI patients is scant and refers to self-rated posttraumatic symptoms. The aim of this study was to investigate the longitudinal course of an interviewer-rated diagnosis of PTSD and PTSD symptom severity following MI. METHODS: Study participants were 40 patients (78% men, mean age 54 +/- 8 years) who were diagnosed with PTSD using the Clinician-administered PTSD Scale (CAPS) after an average of 5 +/- 4 months (range 2-16 months) following an index MI. After a mean follow-up of 26 +/- 6 months (range 12-36 months), 24 patients underwent a second diagnostic interview. RESULTS: Two-thirds of patients (n = 16) still qualified for a diagnosis of PTSD at follow-up. In all 24 patients, total PTSD symptoms (p = 0.001), re-experiencing symptoms (p < 0.001), avoidance symptoms (p = 0.015), and, with borderline significance, hyperarousal symptoms (p < 0.06) had all decreased over time. However, in the subgroup of the 16 patients who had retained PTSD diagnostic status at follow-up, symptoms of avoidance (p = 0.23) and of hyperarousal (p = 0.48) showed no longitudinal decline. Longer duration of follow-up was associated with a greater decrease in avoidance symptoms (p = 0.029) and, with borderline significance, in re-experiencing symptoms (p < 0.07) across all patients. CONCLUSION: Although PTSD symptomatology waned over time and in relation to longer follow-up, two-thirds of patients still qualified for a diagnosis of PTSD 2 years after the initial diagnosis. In post-MI patients, clinical PTSD is a considerably persistent condition.

Report on 2010-2013 Excavations at Horvat Kur, Galilee

Four seasons of excavations at Horvat Kur in the Galilee (250570/754485) have exposed the remains of a broadhouse synagogue from the Byzantine period. The building was entered through a portico on the west or a doorway on the south. The fill beneath the portico included the discarded remains of a once colored mosaic as well as more than 1000 coins. A low bench of basalt stones (some of which were plastered) runs along the interior walls, interrupted only by a stone bemah in the center of the southern wall. The synagogue is thus oriented toward Jerusalem. Near the bemah, an ornamented limestone seat was found in situ atop the bench. The building underwent several changes and repairs in the course of its lifespan. On either side of the bemah, north-south rows of columns rested on stylobate. A basalt stone table was found in re-use in the eastern stylobate. Nicknamed “the Horvat Kur stone,” this monolith features geometric figures on three sides and figurative representations on one side. Its original function is as yet subject of research. A narrow test-trench into the sediment of a cistern located outside the northern wall of the synagogue has produced nearly thirty intact vessels of the early Byzantine period, mostly cooking pots and water jars. In addition a dense sequence of pollen samples has been taken. Preliminary interpretation of these finds indicates that the Horvat Kur synagogue illustrates Byzantine synagogue construction, decoration, and use in the setting of a Galilean village of modest economic circumstances.

The Design of International Trade Agreements: Introducing a New Dataset

Preferential trade agreements (PTAs) have been proliferating for the last twenty years. A large literature has studied various aspects of this phenomenon. Until recently, however, many large-N studies have paid only scant attention to variation across PTAs in terms of content and design. Our contribution to this literature is a new dataset on the design of trade agreements that is the most comprehensive in terms of both variables coded and agreements covered. We illustrate the dataset’s usefulness in re-visiting the questions if and to what extent PTAs impact trade flows. The analysis shows that on average PTAs increase trade flows, but that this effect is largely driven by deep agreements. In addition, we provide evidence that provisions that tackle behind-the-border regulation matter for trade flows. The dataset’s contribution is not limited to the PTA literature, however. Broader debates on topics such as institutional design and the legalization of international relations will also benefit from the novel data.

Ontology and Realism about Modality

A philosopher who thinks substantive necessities obtain in re, this paper argues, need not believe in non-actual worlds, or maximal consistent sets of propositions, but merely in properties. For most properties, on even the sparsest property realism, are flanked by contraries with which they cannot be co-instantiated. True, Armstrong has shown that the impossibility that a property bearer should bear each of two contraries is sometimes just the impossibility that the bearer should be identical with its own proper part-hence is no substantive impossibility. But for many genuine contraries Armstrong's analysis fails; their incompatibility cannot be reduced to facts of identity. The main examples are dispositional properties, so the paper also argues that being dispositional is no bar to a property's being real in its own right.

Von der Lust, im fremden Körper zu denken - offene Manipulation im zeitgenössischen Sprechtheater

Figurentheater für ein erwachsenes Publikum findet vermehrt auch auf den institutionalisierten Bühnen des Sprech-, Tanz- und Musiktheaters statt. Diese Entwicklung steht symptomatisch für eine in allen Künsten beobachtbare Tendenz, Genre- und Formgrenzen zu öffnen. Mit der Auflösung strikter Grenzziehungen zwischen den Künsten sowie der Enthierarchisierung der Theatermittel in postdramatischen Formen werden mittlerweile verstärkt auch in Schauspielinszenierungen Puppen, die gleichberechtigt neben den menschlichen Darsteller_innen agieren, eingesetzt (z. B. Frankenstein, Regie: Philipp Stölzl, Theater Basel 2014; Die Brüder Löwenherz, Regie: Ingo Berk, Puppen: Mervyn Millar, Schauspielhaus Zürich 2014; Der Untergang des Hauses Usher, Regie und Puppen: Suse Wächter, Residenztheater München 2015; Merlin oder das wüste Land, Regie: Jan-Christoph Gockel, Puppen: Michael Pietsch, Schauspielhaus Graz 2015). Der seit etwa 20 Jahren beobachtbare massive Entwicklungsschub im west- und zentraleuropäischen Figurentheater ist eng verknüpft mit der Form der offenen Manipulation, bei der Puppenspieler_innen sichtbar die Spielfigur animieren. Inspiriert ist diese offene Spielweise vom traditionellen japanischen Figurentheater Bunraku, bei dem drei sichtbare Puppenspieler eine Figur animieren. Das Bühnengeschehen wird von einem am Seitenrand der Bühne platzierten Rezitator, welcher die Handlung erzählt und den Text aller Figuren spricht, sowie von einem Shamisen-Spieler begleitet. Während für Vertreter der historischen Avantgarde wie beispielsweise Edward Gordon Craig die Puppe aufgrund ihrer Kontrollierbarkeit als Schauspielerersatz von Interesse war, rückt im zeitgenössischen, offen manipulierenden Figurentheater der Fokus auf die Konfrontation von menschlichen Darsteller_innen und Kunstkörpern. Der Beitrag möchte das evidente Interesse der zeitgenössischen Theaterpraxis an der figurentheaterspezifischen Spielweise der offenen Manipulation zum Ausgangspunkt nehmen, um deren Potenzial zur Fragmentierung, Collagierung und Hybridisierung von Körperkonstruktionen und Körperdarstellungen sowie die damit einhergehenden Fragen nach Subjekt- versus Objektstatus zu untersuchen. Abschliessend soll der Frage nachgegangen werden, welche tradierten schauspieltheoretischen Setzungen mit Blick auf die Möglichkeiten der offenen Manipulation als theatrale Praktik im Sprechtheater einer Revision unterzogen werden müssen.

Identifying Moderator Variables Through Requirements Elicitation Experiments Limitations

Interviews are the most widely used elicitation technique in Requirements Engineering (RE). Despite its importance, research in interviews is quite limited, in particular from an experimental perspective. We have performed a series of experiments exploring the relative effectiveness of structured and unstructured interviews. This line of research has been active in Information Systems in the past years, so that our experiments can be aggregated together with existing ones to obtain guidelines for practice. Experimental aggregation is a demanding task. It requires not only a large number of experiments, but also considering the influence of the existing moderators. However, in the current state of the practice in RE, those moderators are unknown. We believe that analyzing the threats to validity in interviewing experiments may give insight about how to improve further replications and the corresponding aggregations. It is likely that this strategy may be applied in other Software Engineering areas as well.

Monitoring visual attention on a neurorehabilitation environment based on interactive video

The use of new technologies in neurorehabilitation has led to higher intensity rehabilitation processes, extending therapies in an economically sustainable way. Interactive Video (IV) technology allows therapists to work with virtual environments that reproduce real situations. In this way, patients deal with Activities of the Daily Living (ADL) immersed within enhanced environments [1]. These rehabilitation exercises, which focus in re-learning lost functions, will try to modulate the neural plasticity processes [2]. This research presents a system where a neurorehabilitation IV-based environment has been integrated with an eye-tracker device in order to monitor and to interact using visual attention. While patients are interacting with the neurorehabilitation environment, their visual behavior is closely related with their cognitive state, which in turn mirrors the brain damage condition suffered by them [3] [4]. Patients’ gaze data can provide knowledge on their attention focus and their cognitive state, as well as on the validity of the rehabilitation tasks proposed [5].

Towards the automatic generation of card games through Grammar-Guided Genetic Programming

We demonstrate generating complete and playable card games using evolutionary algorithms. Card games are represented in a previously devised card game description language, a context-free grammar. The syntax of this language allows us to use grammar-guided genetic programming. Candidate card games are evaluated through a cascading evaluation function, a multi-step process where games with undesired properties are progressively weeded out. Three representa- tive examples of generated games are analysed. We observed that these games are reasonably balanced and have skill ele- ments, they are not yet entertaining for human players. The particular shortcomings of the examples are discussed in re- gard to the generative process to be able to generate quality games

Recubrimientos autolubricantes cuasicristalinos tipo composite depositados mediante proyección térmica para aplicaciones espaciales y de alta temperatura

Los recubrimientos lubricantes sólidos son requeridos para reducir la fricción y prevenir el desgaste en componentes que operan a altas temperaturas o en vacío (vehículos espaciales, industria química, motores diésel, turbinas aeronáuticas y de generación de energía…). Los lubricantes líquidos pierden sus características cuando las condiciones de presión, temperatura o ambientales son severas (oxidación, inestabilidad térmica, volatilidad,…), por ejemplo los aceites minerales convencionales se descomponen a temperaturas próximas a 200 ºC. Por tanto, la única manera de poder conseguir una adecuada lubricación a temperaturas extremas es por medio de sólidos, que cada vez más, se aplican en forma de recubrimientos. Estos recubrimientos podrían ser empleados en componentes de vehículos espaciales reutilizables, donde se pueden alcanzar, en la reentrada en la atmósfera, temperaturas de 700 ºC (bisagras, rodamientos, articulaciones y zonas de sellado en las superficies de control, y rodamientos de las turbobombas y las cajas de engranajes). Dichos recubrimientos también deberían ser capaces de proporcionar una lubricación efectiva a bajas temperaturas para las operaciones en tierra, para las operaciones de arranque en frío, incluso en el espacio. El conjunto de requisitos que tendrían que satisfacer las capas tribológicas relacionadas con estas condiciones extremas es muy diverso, lo que hace que el concepto de capas tipo composite (aquéllas constituidas por varios componentes) sea, en principio, muy adecuado para estas aplicaciones. Recubrimientos composite proyectados térmicamente constituidos por una matriz dura y conteniendo lubricantes sólidos pueden ser una buena solución desde el punto de vista tribológico. El “Lewis Research Centre” de la NASA ha estado desarrollando recubrimientos autolubricantes tipo composite, constituidos por la combinación de materiales duros como el carburo de cromo, junto con lubricantes sólidos como plata o la eutéctica de fluoruros de calcio y bario, en una matriz de NiCr, para su uso en aplicaciones terrestres a alta temperatura. Estos recubrimientos han sido aplicados mediante proyección térmica, siendo denominados como series PS100, PS200, PS300 y PS400, reduciendo de forma significativa el coeficiente de fricción y mejorando la resistencia al desgaste en un amplio margen de temperaturas. Otra nueva familia de materiales con comportamiento tribológico prometedor son las aleaciones cuasicristalinas (QC). Presentan características muy atractivas: alta dureza, baja fricción, alto límite elástico de compresión... Son muy frágiles como materiales másicos, por lo que se intentan aplicar en forma de recubrimientos. Se pueden depositar mediante proyección térmica. Algunos de estos materiales cuasicristalinos, como AlCoFeCr, poseen coeficientes de dilatación próximos al de los materiales metálicos, alta estabilidad térmica, baja conductividad térmica y una elevada resistencia a la oxidación y a la corrosión en caliente. En esta tesis se han desarrollado recubrimientos tipo composite conteniendo cuasicristales como componente antidesgaste, NiCr como componente tenaz, y Ag y la eutéctica de BaF2-CaF2, como lubricantes sólidos. Estos recubrimientos han sido depositados con diferentes composiciones (denominadas TH100, TH103, TH200, TH400, TH600…) mediante distintos procesos de proyección térmica: plasma en aire (PS), plasma en baja presión (LPPS) y combustión a alta velocidad (HVOF). Los recubrimientos se han generado sobre el sustrato X-750, una superaleación base níquel, endurecible por precipitación, con muy buena resistencia mecánica y a la oxidación hasta temperaturas de 870 ºC y, además, es empleada en aplicaciones aeroespaciales e industriales. Los recubrimientos han sido caracterizados microestructuralmente en INTA (Instituto Nacional de Técnica Aeroespacial), mediante SEM-EDS (Scanning Electronic Microscopy-Energy Dispersive Spectroscopy) y XRD (X-Ray Diffraction), y tribológicamente mediante medidas de microdureza y ensayos en tribómetro POD (Pin On Disc) para determinar los coeficientes de fricción y de desgaste. Los recubrimientos han sido ensayados tribológicamente a alta temperatura en INTA y en vacío en AMTTARC (Aerospace and Space Materials Technology Testhouse – Austrian Research Centres), en Seibersdorf (Austria). Se ha estudiado la influencia de la carga normal aplicada, la velocidad lineal y el material del pin. De entre las diferentes series de recubrimientos cuasicristalinos tipo composite desarrolladas, dos de ellas, TH100 y TH103 han presentado una excelente calidad microestructural (baja porosidad, distribución uniforme de fases…) y se han mostrado como excelentes recubrimientos antidesgaste. Sin embargo, estas capas presentan un pobre comportamiento como autolubricantes a temperatura ambiente, aunque mejoran mucho a alta temperatura o en vacío. Los resultados del trabajo presentado en esta tesis han proporcionado nuevo conocimiento respecto al comportamiento tribológico de recubrimientos autolubricantes cuasicristalinos tipo composite depositados por proyección térmica. Sin embargo, dichos resultados, aunque son muy prometedores, no han puesto de manifiesto el adecuado comportamiento autolubricante que se pretendía y, además, como ocurre en cualquier trabajo de investigación, durante el desarrollo del mismo siempre aparecen nuevas dudas por resolver. Se proponen nuevas líneas de trabajo futuro que complementen los resultados obtenidos y que puedan encaminar hacia la obtención de un recubrimiento que mejore su comportamiento autolubricante. ABSTRACT Solid lubricant coatings are required to reduce friction and prevent wear in components that operate at high temperatures or under vacuum (space vehicles, chemical industry, diesel engines, power generation turbines and aeronautical turbines, for instance). In these cases neither greases nor liquid lubricants can be employed and the only practicable approach to lubrication in such conditions is by means of solids. These are increasingly applied in the form of coatings which should exhibit low shear strength, whilst maintaining their chemical stability at extremes temperatures and in the space environment. In the space field, these coatings would be employed in re-usable space plane applications, such as elevon hinges, where temperatures of 700 ºC are reached during re-entry into the Earth’s atmosphere. These coatings should also be capable of providing effective lubrication at lower temperatures since “cold start” operation may be necessary, even in the space environment. The diverse and sometimes conflictive requirements in high temperature and space-related tribological coatings make the concept of composite coatings highly suitable for these applications. Thermal-sprayed composites containing solid lubricants in a hard matrix perform well tribologically. NASA‘s Lewis Research Centre had developed self-lubricating composite coatings for terrestrial use, comprising hard materials like chromium carbide as well as solid lubricant additives such as silver and BaF2-CaF2 eutectic on a Ni-Cr matrix. These coatings series, named PS100, PS200, PS300 and PS400, are applied by thermal spray and significantly reduce friction coefficients, improving wear resistance over a wide temperature range. Quasicrystalline alloys (QC) constitute a new family of materials with promising tribological behaviour. Some QC materials exhibit a combination of adequate antifriction properties: low friction coefficient, high hardness and high yield strength under compression, and can be easily produced as coatings on top of metallic and non-metallic materials. Among these QC alloys, AlCoFeCr has high hardness (700 HV0.1), a thermal expansion coefficient close to that of metals, high thermal stability, low thermal conductivity and good oxidation and hot corrosion resistance. However most QC materials have the disadvantage of being very brittle. In order to take advantage of the excellent tribological properties of QCs, thick composite lubricant coatings were prepared containing them as the hard phase for wear resistance, Ag and BaF2-CaF2 eutectic as lubricating materials and NiCr as the tough component. These coatings were deposited in different composition mixtures (named TH100, TH103, TH200, TH400, TH600…) by different thermal spray processes: air plasma spray (PS), low pressure plasma spray (LPPS) and high velocity oxy-fuel (HVOF), on X-750 substrates. X-750 is an age-hardenable nickel-base superalloy with very good strength and a good resistance to oxidising combustion gas environments at temperatures up to about 870 ºC and it is widely used in aerospace and industrial applications. Coatings have been characterized microstructurally, at INTA (National Institute for Aerospace Technology), by means of SEM-EDS (Scanning Electronic Microscopy- Energy Dispersive Spectroscopy) and XRD (X-Ray Diffraction), and tribologically by microhardness measurements and pin-on-disc testing to determine friction coefficients as well as wear resistance. The coatings were tested tribologically at high temperature at INTA and under vacuum at AMTT-ARC (Aerospace and Space Materials Technology Testhouse – Austrian Research Centres), in Seibersdorf (Austria). Different loads, linear speeds and pin materials were studied. TH100 and TH103 QC alloy matrix composite coatings were deposited by HVOF with excellent microstructural quality (low porosity, uniform phase distribution) and showed to be excellent wear resistant coatings. However these QC alloy matrix composite coatings are poor as a self-lubricant at room temperature but much better at high temperature or in vacuum. The results from the work performed within the scope of this thesis have provided new knowledge concerning the tribological behavior of self-lubricating quasicrystalline composite coatings deposited by thermal spraying. Although these results are very promising, they have not shown an adequate self-lubricating behavior as was intended, and also, as in any research, the results have in addition raised new questions. Future work is suggested to complement the results of this thesis in order to improve the selflubricating behaviour of the coatings.

Estimativa da incidência de câncer nas redes regionais de saúde e municípios do estado de São Paulo, 2010

Introdução: Estatísticas sobre a ocorrência de casos novos de câncer são fundamentais para o planejamento e monitoramento das ações de controle da doença. No estado de São Paulo, a incidência de câncer é obtida indiretamente por meio de estimativas oficiais (para o estado como um todo e sua capital) e, de forma direta, em municípios cobertos por Registro de Câncer de Base Populacional (RCBP). Existem, atualmente, três RCBP ativos (São Paulo, Jaú e Santos), um inativo (Barretos) e um em reimplantação (Campinas). Dado o desconhecimento do panorama da incidência de câncer em áreas não cobertas por RCBP, este estudo teve como objetivo estimar a incidência de câncer, calcular taxas brutas e padronizadas por idade, específicas por sexo e localização primária do tumor para as 17 Redes Regionais de Atenção à Saúde (RRAS) de São Paulo e municípios, em 2010. Método: Utilizou-se como estimador da incidência de câncer a razão Incidência/Mortalidade (I/M), por sexo, grupo etário quinquenal dos 0 aos 80 anos e localização primária do tumor. O numerador da razão foi formado pelo número agregado de casos novos entre 2006-2010, em dois RCBP ativos (Jaú e São Paulo, respectivamente, com cobertura correspondente a 0,3 por cento e 27,3 por cento da população estadual). No denominador, o número de óbitos oficial nas respectivas áreas e período. O número estimado de casos novos resultou da multiplicação das I/M pelo número de óbitos por câncer registrados em 2010 para o conjunto de municípios formadores de cada uma das RRAS ou para cada município. O método de referência foi aquele utilizado no Globocan series, da Agência Internacional de Pesquisa contra o Câncer. O ajuste por idade das taxas de incidência ocorreu pelo método direto, tendo como padrão a população mundial. Resultados: Estimaram-se 53.476 casos novos de câncer para o sexo masculino e 55.073 casos para o feminino (excluindo-se os casos de câncer de pele não melanoma), com taxas padronizadas de 261/100.000 e 217/100.000, respectivamente. No sexo masculino, a RRAS 6 apresentou para todos os cânceres a maior taxa de incidência padronizada (285/100.000), e a RRAS 10, a menor (207/100.000). Os cânceres mais incidentes em homens foram próstata (77/100.000), cólon/reto/anus (27/100.000) e traqueia/brônquio/pulmão (16/100.000). Entre as mulheres, as taxas de incidência padronizadas por idade foram de 170/100.000 (RRAS 11) a 252/100.000 (RRAS 07); o câncer de mama foi o mais incidente (58/100.000), seguido pelos tumores de cólon/reto/anus (23/100.000) e de colo uterino (9/100.000). Conclusões: Os resultados apontaram diferentes padrões de incidência com taxas que ultrapassaram a magnitude estadual. Dados provenientes de RCBP locais podem ser usados na obtenção indireta de estimativas regionais e locais. Neste estudo, as taxas de incidência apresentadas podem estar sub ou superestimadas refletindo a qualidade, completitude e padrões observados no RCBP de maior representatividade considerado na análise.

Evaluating knowledge-based approaches to the multilingual extension of a temporal expression normalizer

The extension to new languages is a well known bottleneck for rule-based systems. Considerable human effort, which typically consists in re-writing from scratch huge amounts of rules, is in fact required to transfer the knowledge available to the system from one language to a new one. Provided sufficient annotated data, machine learning algorithms allow to minimize the costs of such knowledge transfer but, up to date, proved to be ineffective for some specific tasks. Among these, the recognition and normalization of temporal expressions still remains out of their reach. Focusing on this task, and still adhering to the rule-based framework, this paper presents a bunch of experiments on the automatic porting to Italian of a system originally developed for Spanish. Different automatic rule translation strategies are evaluated and discussed, providing a comprehensive overview of the challenge.

The New Financial Regulatory Paradigm: A transatlantic perspective. CEPS Policy Brief No. 287, 21 March 2013

This CEPS Policy Brief reviews key aspects of the new financial paradigm in a transatlantic perspective, focusing on the general approach in EU and US legislation in response to the financial crisis and the G-20 commitments and specifically as regards the extraterritorial implications. Following discussion of the institutional setting, conclusions are offered on what these changes mean in the context of the recently proposed Transatlantic Trade and Investment Partnership. In comparing the EU and the US efforts in re-engineering their regulatory regimes in response to the financial crisis, the paper finds, with the notable exception of the banking union, serious grounds for concern that the outcome may be an even more fragmented European financial market, access to which for third-country institutions is highly problematic.

Priorities for the Juncker Commission: Policy recommendations and advice from the research team at CEPS. CEPS Special Report No. 92, 22 October 2014

In the months leading up to his nomination as President of the European Commission by the European Council in June 2014 through to his approval by the European Parliament in mid-July and finally his approval at a second special summit in August, CEPS’ researchers have closely followed the travails of Jean-Claude Juncker. We have also carefully studied his fundamental restructuring of the College in re-grouping commissioners around seven project teams, each headed by a vice-president. In our view, these changes promise to improve internal coordination, policy-making and transparency of rule-making and hopefully will reduce the personalisation of portfolios. This Special Report brings together under a single cover a series of 14 separate commentaries prepared by senior CEPS researchers, offering their assessment of these profound changes underway and their policy advice to the new commissioners from the perspective of their field of specialisation.
