description: In design of optical systems based on LED (Light emitting diode) technology, a crucial task is to handle the unstructured data describing properties of optical elements in standard formats. This leads to the problem of data fitting within an appropriate model. Newton's method is used as an upgrade of previously developed most promising discrete optimization heuristics showing improvement of both performance and quality of solutions. Experiment also indicates that a combination of an algorithm that finds promising initial solutions as a preprocessor to Newton's method may be a winning idea, at least on some datasets of instances.

description: We show that the S/F/S Josephson $φ_0$-junction permits detection of macroscopic quantum tunneling and quantum oscillation of the magnetic moment by measuring the ac voltage across the junction. Exact expression for the tunnel splitting renormalized by the interaction with the superconducting order parameter is obtained. It is demonstrated that magnetic tunneling may become frozen at a sufficiently large $φ_0$. The quality factor of quantum oscillations of the magnetic moment due to finite Ohmic resistance of the junction is computed. It is shown that magnetic tunneling rate in the $φ_0$-junction can be controled by the supercurrent, with no need for the magnetic field.

description: Introducing an isolated intermediate band (IB) into a wide band gap semiconductor can potentially improve the optical absorption of the material beyond the Shockley-Queisser limitation for solar cells. Here, we present a systematic study of the thermodynamic stability, electronic structures, and optical properties of transition metals (M = Ti, V, and Fe) doped CuAlSe2 for potential IB thin film solar cells, by adopting the first-principles calculation based on the hybrid functional method. We found from chemical potential analysis that for all dopants considered, the stable doped phase only exits when the Al atom is substituted. More importantly, with this substitution, the IB feature is determined by $3d$ electronic nature of M^{3+} ion, and the electronic configuration of 3d^1 can drive a optimum IB that possesses half-filled character and suitable subbandgap from valence band or conduction band. We further show that Ti-doped CuAlSe2 is the more promising candidate for IB materials since the resulted IB in it is half filled and extra absorption peaks occurs in the optical spectrum accompanied with a largely enhanced light absorption intensity. The result offers a understanding for IB induced by transition metals into CuAlSe2 and is significant to fabricate the related IB materials.

description: This article aims at establishing a wider understanding of the evolution of spatial clusters. It will be argued that the potential to generate regional growth is dependent on the way a cluster emerges. Two models of cluster formation will be distinguished in detail – start-up clusters and unrelated spatial concentrations. In its sectoral orientation the study is focused on nanotechnology, a key(technology)-industry said to contribute to new growth spurts in the industrialised world. By analysing the evolution of regional clusters in the Saarland and in Berlin-Brandenburg it will be shown that both types of cluster formation can be found in nanotechnology, demanding different modes of policy intervention.

description: Due to the general globalisation of the German real estate market the open-ended real estate funds diversify their portfolios globally. This development became possible because of legal deliberalisation and the rising demand for internationally diversified investment products. The paper investigates the question whether a geographically diversification of open-ended real estate funds is an appropriate strategy for achieving a better fund performance. For these purposes the data of 16 open ended real estate funds were analysed. The results are not unambiguous but tend to argue for a positive correlation of level of diversification and fund performance.

description: Bürgerbeteiligung in Planungsprozessen besitzt in Deutschland eine lange Tradition. Im Städtebauförderungsgesetz wurde 1971 ein weitgehender Bürgerbeteiligungsansatz verankert, der Niederschlag in verschiedenen formalen Instrumenten aber auch informellen Beteiligungsformen findet. Ursprüngliche Formen der Bürgerbeteiligung richteten sich vornehmlich an von Planungen und Maßnahmen betroffene Bürger und eröffneten ihnen die Möglichkeit der Teilhabe an konkreten Planungsprozessen im Rahmen der gesetzlichen Vorschriften. Darüber hinaus setzen Politik und Verwaltung auch auf informelle, d.h. nicht-normierte Formen der Bürgerbeteiligung, die es den Bewohnern ermöglichen sollen, ihre Vorstellungen über die Entwicklung ihrer Stadt zu artikulieren und sich in diesen Entwicklungsprozess einzubringen. In der Praxis offenbaren sich jedoch häufig Diskrepanzen zwischen der eingeforderten Beteiligung und dem Erfolg dieser Teilhabe. So kritisiert Selle (2007), dass im Planungsalltag vieler Kommunen Teilhabebemühungen an ihre Grenzen und auf Widerstand stoßen, wobei die Gründe hierfür vielfältig sind.

description: The nematic ordering in semiflexible polymers with contour length $L$ exceeding their persistence length $\ell_p$ is described by a confinement of the polymers in a cylinder of radius $r_{eff}$ much larger than the radius $r_ρ$, expected from the respective concentration of the solution. Large scale Molecular Dynamics simulations combined with Density Functional Theory are used to locate the Isotropic-Nematic ($I-N$)-transition and to validate this cylindrical confinement. Anomalous fluctuations, due to chain deflections from neighboring chains in the nematic phase are proposed. Considering deflections as collective excitations in the nematically ordered phase of semiflexible polymers elucidates the origins of shortcomings in the description of the $I-N$ transition by existing theories.

description: Die Zunahme internationaler Migrationsbewegungen ist eines der wichtigsten Phänomene des ausgehenden 20. und des beginnenden 21. Jahrhunderts. In den vergangenen Jahrzehnten stieg die Anzahl von Menschen, die sich längerfristig außerhalb ihres Geburtslandes aufhielten, von 82 Mio. im Jahr 1975 über 175 Mio. im Jahr 2000 auf annähernd 200 Mio. im Jahr 2005, was einem Anteil von 3 % an der Weltbevölkerung entspricht.1 Neben dieser quantitativen Veränderung internationaler Migrationsprozesse ist jedoch auch eine qualitative Veränderung in den Voraussetzungen, Verläufen und individuellen Organisationsformen von Migration auszumachen: Parallel zu der lange Zeit dominierenden Form internationaler Migration als einmaligem und endgültigem Mobilitätsvorgang entwickelte sich eine transnationale Form der Migration, die geprägt ist durch mehrfache Verlagerungen des Wohnsitzes über internationale Grenzen hinweg und durch die Aufrechterhaltung intensiver sozialer Bezüge zwischen Herkunfts- und Ankunftsort.2 Eine Reaktion auf diese Veränderungen ist der Wandel der Forschungsperspektive in der internationalen Migrations- und Integrationsforschung, die sich zunehmend auf die transnationalen Bezüge von Migranten und die Folgen dieser Verbindungen für die Migranten selbst sowie für die Herkunfts- und die Ankunftsgesellschaften ausrichtet. Die Theorieansätze zur transnationalen Migration und zu transnationalen sozialen Räumen sind dabei die Ausgangsbasis für empirische Arbeiten zu dem Phänomen.

description: Unter den Bedingungen eines entspannten Wohnungsmarktes spielt das Image von Wohngebieten und Quartierstypen für deren Stabilität eine zunehmend wichtige Rolle. Die Entwicklung eines Wohngebietes wird dann als stabil bezeichnet, wenn die Nachfrage nach Wohnungen ausreichend hoch ist, um langfristig aus der Vermietung bzw. dem Verkauf von Wohnungen Investitionsmittel für den Erhalt bzw. die Erneuerung des Bestandes zu erwirtschaften. Eine geringe Nachfrage der Wohnungen unter bzw. im Bereich der Grenze der Wirtschaftlichkeit bedeutet hingegen eine instabile Entwicklung, die zum Abriss einzelner Gebäuden bzw. ganzer Viertel führt. In diesem Sinne können die Bewohner einer Stadt durch ihre Entscheidung für oder gegen einen bestimmten Wohnstandort aktiv die Entwicklung von Quartieren mit beeinflussen.

description: Strukturwandel ein, der sich u. a. in einer grundlegenden Reorganisation der industriellen Produktionsbasis widerspiegelte. Die industriell geprägten Stadtregionen waren – sie vereinigten Ende der 1980er Jahre etwa ein Viertel der industriellen Bestandsflächen der damaligen DDR auf sich (vgl. USBECK 1999, S. 1) – in besonderer Intensität von Betriebsschließungen betroffen. Einer zügigen Revitalisierung der innenstadtnahen Alt-Gewerbestandorte standen – von gesamtwirtschaftlichen Aspekten abgesehen – deren schlechte infrastrukturelle Anbindung, schwierige Verhältnisse am Bodenmarkt (ungeklärte Eigentumsfragen, hohes Preisniveau etc.), sowie Altlastenprobleme entgegen. Erschwert wurde die Situation ferner durch die Ausweisung neuer Gewerbegebiete im Umland der Städte oder an deren Rändern, da diese Areale über vergleichsweise bessere Standortbedingungen verfügten, und damit nicht nur Unternehmen von außerhalb der Region anzogen, sondern auch die Verlagerung von Unternehmen aus den innerstädtischen Gebieten begünstigten (vgl. USBECK 1999, S. 3), so dass die ursprünglichen Standorte zunehmend von Leerstand betroffen waren.

description: The general objective of this article was to investigate the factors that determine the performance of woodwork and metalwork enterprises in Makueni District. The results showed that working capital, licensing, competition and the level of education were statistically significant in determination of profits. Based on the findings, it is recommended that the government and other stakeholders should provide both financial and non-financial services at affordable rates to the small business operators and entrepreneurs. Loans inform of money or kind should be made available through relevant lending institutions to supplement the working capital. Seminars and conferences should be held to create awareness to the entrepreneurs of the various incentives and credit facilities provided by the government and other stakeholders. To reduce the level of competition, the government should allocate land to the entrepreneurs and structures put up at affordable rates.
Charge-dependent anisotropic flow in Cu+Au collisions

description: We present the first measurements of charge-dependent directed flow in Cu+Au collisions at t $\sqrt{s_{NN}}$ = 200 GeV. The directed flow has been measured as functions of the transverse momentum and pseudorapidity with the STAR detector. The results show a small but finite difference between positively and negatively charged particles. The difference is qualitatively explained by the patron-hadron-string-dynamics (PHSD) model including the effect of the electric field, but much smaller than the model calculation, which indicates only a small fraction of all final quarks are created within the lifetime of the initial electric field. Higher-order azimuthal anisotropic flow is also presented up to the fourth-order for unidentified charged particles and up to the third-order for identified charged particles (π, K, and p). For unidentified particles, the results are reasonably described by the event-by-event viscous hydrodynamic model with η/s=0.08-0.16. The trends observed for identified particles in Cu+Au collisions are similar to those observed in symmetric (Au+Au) collisions.

description: “Diamonds love Antwerp” – these three words constitute the present slogan of the Antwerp World Diamond Centre, the organisation concerned with the promotion of the diamond trade and industry in the Scheldt city and keeping the latter an important diamond hub in the age of globalisation with new diamond centres evolving especially in low-cost countries like China and Thailand (The New York Times, May 31 2005; EVEN-ZOHAR 2006, 371ff.). In fact, diamonds seem to have loved Antwerp even in the past as the city has been a major centre for trading and polishing the precious stones since the 15th century (WALGRAVE 1993, 37). Despite some ups and downs there had not been any interruption of the commercial activities in this sector until World War II reached Belgium and trading as well as processing diamonds gradually were discontinued (LAUREYS 2005, chapter 5f). Surprisingly, however, the Belgian diamond sector experienced a long-lasting boom after 1945, contributing significantly to the country’s economic power even though the former infrastructure had partly been taken away or destroyed, many workers had fled, been deported or killed and other diamond centres had evolved during the years of the German occupation (VAN DYCK 1989). Given these aspects, the paper on hand addresses the question whether the window of locational opportunity arising after the abrupt break of the trajectory was restricted by past structures that actually have favoured the re-emergence of the cluster at its former location. By doing so, two aspects of conceptual interest are concerned as well: On the one hand, evolutionary literature up to now has emphasised chance as the major determinant of the emergence of regional trajectories thereby neglecting the underlying social processes. Furthermore, due to the concentration on concepts like path-dependency and lock-in potential ruptures in the development of clusters were only seldom taken into account yet (BATHELT/BOGGS 2005; 2003).

description: Background: The non-classical human leukocyte antigen (HLA)-G is a strong immunomodulatory molecule. Under physiological conditions, HLA-G induces immunological tolerance in immune privileged tissues, while under pathophysiological situations it contributes to immune escape mechanisms. Therefore, HLA-G could act as a potential immune checkpoint for future anti-cancer immunotherapies. Recent data suggest an aberrant expression of the cAMP response element binding protein (CREB) in clear cell renal cell carcinoma (ccRCC), which is correlated with tumor grade and stage. Furthermore, preliminary reports demonstrated a connection of CREB as a control variable of HLA-G transcription due to CREB binding sites in the HLA-G promoter region. This study investigates the interaction between CREB and HLA-G in different renal cell carcinoma (RCC) subtypes and its correlation to clinical parameters. Methods: The direct interaction of CREB with the HLA-G promoter was investigated by chromatin immunoprecipitation in RCC cell systems. Furthermore, the expression of CREB and HLA-G was determined by immunohistochemistry using a tissue microarray (TMA) consisting of 453 RCC samples of distinct subtypes. Staining results were assessed for correlations to clinical parameters as well as to the composition of the immune cell infiltrate. Results: There exists a distinct expression pattern of HLA-G and CREB in the three main RCC subtypes. HLA-G and CREB expression were the lowest in chromophobe RCC lesions. However, the clinical relevance of CREB and HLA-G expression differed. Unlike HLA-G, high levels of CREB expression were positively associated to the overall survival of RCC patients. A slightly, but significantly elevated number of tumor infiltrating regulatory T cells was observed in tumors of high CREB expression. Whether this small increase is of clinical relevance has to be further investigated. Conclusions: An interaction of CREB with the HLA-G promoter could be validated in RCC cell lines. Thus, for the first time the expression of CREB and its interaction with the HLA-G in human RCCs has been shown, which might be of clinical relevance.

description: Purpose: The coronavirus disease 2019 (COVID-19) poses major challenges to health-care systems worldwide. This pandemic demonstrates the importance of timely access to intensive care and, therefore, this study aims to explore the accessibility of intensive care beds in 14 European countries and its impact on the COVID-19 case fatality ratio (CFR). Methods: We examined access to intensive care beds by deriving (1) a regional ratio of intensive care beds to 100,000 population capita (accessibility index, AI) and (2) the distance to the closest intensive care unit. The cross-sectional analysis was performed at a 5-by-5 km spatial resolution and results were summarized nationally for 14 European countries. The relationship between AI and CFR was analyzed at the regional level. Results: We found national-level differences in the levels of access to intensive care beds. The AI was highest in Germany (AI = 35.3), followed by Estonia (AI = 33.5) and Austria (AI = 26.4), and lowest in Sweden (AI = 5) and Denmark (AI = 6.4). The average travel distance to the closest hospital was highest in Croatia (25.3 min by car) and lowest in Luxembourg (9.1 min). Subnational results illustrate that capacity was associated with population density and national-level inventories. The correlation analysis revealed a negative correlation of ICU accessibility and COVID-19 CFR (r = − 0.57; p < 0.001). Conclusion: Geographical access to intensive care beds varies significantly across European countries and low ICU accessibility was associated with a higher proportion of COVID-19 deaths to cases (CFR). Important differences in access are due to the sizes of national resource inventories and the distribution of health-care facilities relative to the human population. Our findings provide a resource for officials planning public health responses beyond the current COVID-19 pandemic, such as identifying potential locations suitable for temporary facilities or establishing logistical plans for moving severely ill patients to facilities with available beds.

description: Background: Rheumatoid arthritis (RA) and periodontitis (PD) are proven to share common risk markers, including genetic factors. In the present study we focused on genetic variants in PTPN22 (rs2476601), PADI4 (rs2240340), CTLA4 genes (rs3087243) and its impact on RA and PD. Materials and methods: In the study 111 RA patients and 256 systemically healthy controls were involved. A subdivision of patients and controls was carried out according the severity of periodontitis (no/level 1 PD vs. level 2 PD). Results: I. Evaluating the genetic impact on the occurrence of RA the T allele of rs2476601 (PTPN22) (bivariate: p < 0.001; multivariate: p = 0.018) and T allele of rs2240340 (PADI4) (bivariate: p = 0.006; multivariate: p = 0.070) were associated with an increased vulnerability to RA. II. Investigating the genetic influence on level 2 PD the T allele of rs2476601 (PTPN22) was shown to be associated with a higher susceptibility to PD within the RA group (bivariate: p = 0.043; multivariate: p = 0.024). III. The T allele of rs2476601 (PTPN22) was proven to be a significant marker of RA and level 2 PD comorbidity (bivariate: p < 0.001; multivariate: p = 0.028). Conclusions: These results support the thesis that genetic variations may represent a possible link between PD and RA. The study increases knowledge about disease-specific and cross-disease genetic pattern.

description: El proyecto de investigación titulado “Afrontamiento de mujeres víctimas de reclutamiento forzado que desertaron de grupos organizados al margen de la ley –GOAML” siendo menores de edad, tuvo como propósito identificar las estrategias de afrontamiento que usaron un grupo de mujeres para seguir con su proyecto de vida sin acompañamiento del Estado. Como objetivos específicos se describieron las circunstancias vividas durante el reclutamiento y posterior a la inserción a la vida civil y también se identificaron los vacíos en la política pública existente para que estas mujeres accedan a la reparación integral por parte del Estado. La metodología se enmarcó en un diseño fenomenológico, por medio del cual se pretende describir un fenómeno desde el punto de vista del participante, basándose en el análisis del discurso, así como en su significado (Hernández, Fernández & Baptista, 2014), en población escogida entre un grupo de mujeres participantes en el proyecto “Uniendo voces, tejiendo esperanzas” de la ONG cordobesa Corporación para el Desarrollo Social Comunitario (CORSOC), dirigido al empoderamiento de mujeres sobrevivientes de violencia sexual al interior del conflicto armado. Como resultado del estudio se encontró que, a pesar de la falta de orientación psicosocial, las mujeres usaron mecanismos de afrontamiento como el escape-evitación y en especial, la reevaluación positiva y que las circunstancias de su deserción hicieron difícil demostrar su derecho a la reparación como víctimas del delito de reclutamiento ilícito bajo la actual legislación, lo que las hace quedar como victimas silenciosas de uno de los delitos atroces establecidos en los DIH.

description: We consider non-Abelian strings in N=2 supersymmetric QCD with the U$(N)$ gauge group and $N_f=N$ quark flavors deformed by a mass term for the adjoint matter. This deformation breaks N=2 supersymmetry down to N=1. Dynamics of orientational zero modes on the string world sheet are described then by CP$(N-1)$ model with N=(0,2) supersymmetry. We study the string of a finite length $L$ assuming compactification on a cylinder (periodic boundary conditions). The world-sheet theory is solved in the large-$N$ approximation. We find a rich phase structure in the $(L, \,u)$ plane where $u$ is a deformation parameter. At large $L$ and intermediate $u$ we find a phase with broken $Z_{2N}$ symmetry, $N$ vacua and a mass gap. At large values of $L$ and $u$ still larger we have the $Z_{2N}$-symmetric phase with a single vacuum and massless fermions. In both phases N=(0,2) supersymmetry is spontaneously broken. We also observe a phase with broken SU$(N)\;$ symmetry at small $L$. In the latter phase the mass gap vanishes and the vacuum energy is zero in the leading $1/N$ approximation. However, we expect that $1/N$ corrections will break N=(0,2) supersymmetry. We also discuss how this rich phase structure matches the N=(2,2) limit in which the world-sheet theory has a single phase with the mass gap independent of $L$.

description: Background: International Medical Graduates (IMGs) encounter barriers as they seek to match into fellowship programs in the United States (US). This study’s objective is to determine if there are differences in letters of recommendation written for IMGs compared to U.S. Medical Graduates (USMGs) applying to pulmonary and critical care medicine (PCCM) fellowship programs. Methods: All applications submitted to a PCCM fellowship program in 2021 were included in this study. The applicant demographics and accomplishments were mined from applications. The gender of letter writers was identified by the author’s pronouns on professional websites. Word count and language differences in the letters were analyzed for each applicant using the Linguistic Inquiry and Word Count (LWIC2015) program. Multivariable linear regressions were performed controlling for applicant characteristics to identify if IMG status was associated with total word count and degree of support, measured by a composite outcome encompassing several categories of adjectives, compared to USMG status. Results: Of the 573 applications, most of the applicants were USMGs (72%, N = 334/573). When adjusting for applicant characteristics, IMG applicants had shorter letters of recommendation (87.81 total words shorter 95% CI: − 118.61, − 57.00, p-value < 0.01) and less supportive letters (4.79 composite words shorter 95% CI: − 6.61, − 2.97, p-value < 0.01), as compared to USMG applicants. Notably, female IMG applicants had the biggest difference in their word counts compared to USMG applicants when the letter writer was a man. Conclusions: IMG applicants to a PCCM fellowship received shorter and less supportive letters of recommendation compared to USMG applicants.

description: A 37-year-old female underwent an emergent implant of a covered self-expandable stent graft (8mm x 10cm Viabahn, W. L. Gore) due to acute bleeding from a femoral access following closure of a patent foramen ovale. Over the following months, intermittent claudication developed, progressively more incapacitant. Work-up revealed near-occlusion of the stent graft due to edge stenosis. Elective explant of the stent graft was performed, revealing extensive proximal and distal edge miointimal hyperplasia (marked with *). Endarterectomy was performed and the arterial defect was corrected with a bovine pericardium patch.

description: Los objetivos del presente trabajo de investigación fueron determinar el porcentaje de aceite adsorbido por aserrines y realizar la caracterización fisicoquímica de tres especies forestales nativas de la Costa Caribe colombiana: Cedro (Cedrela Odorata L), Camajón (Sterculia apétala), Ceiba Amarilla (Hura Crepitans L.), explorando una solución alternativa a la problemática ambiental, de aceites pesados en agua, utilizando materiales orgánicos, catalogado como desecho. Las muestras de madera utilizadas fueron obtenidas en un taller de Carpintería en los departamentos de Sucre y Bolívar, tamizadas en mallas de 10 y 18 mesh, recolectando la fracción que pasó por ella. Fué lavada y secada para su utilización. Se investigó el potencial del aserrín en experiencias en el laboratorio con Diesel como aceite pesado; estos estuvieron en contacto por un tiempo 10 min en frascos de vidrio, permitiendo la interacción entre estos, para favorecer la penetración y permeación. Seguidamente a la separación del aserrín de la solución, las muestras fueron sometidas a ensayos Soxhlet y a cromatografía de gases para determinar la cantidad de aceite adsorbido, la cual varió en los tres tipos de muestra, debido a la composición fisicoquímicas en cada tipo de madera. La capacidad máxima de adsorción fué arrojada por Cedrela Odorata L (58.51%), seguido por Hura Crepitans L (58,13%), y por último Sterculia Apétala (34,15%), bajo las condiciones de mayor cantidad de aserrín (5 g) y tamaño de partícula menor (1 mm). Los espectros infrarrojos muestran la química de cada aserrín utilizado, es decir, sus compuestos hidrofóbicos e hidrofílicos, y los resultados obtenidos experimentalmente, están acordes a lo que arrojó el análisis FTIR. Luego, establecidas las condiciones que mejor remueve y el tipo de aserrín que obtuvo el mejor resultado, se evaluó el potencial de adsorción de Cedrela Odorata L, hasta alcanzar un punto de saturación aproximadamente de 13.13 mg/L, siendo lo máximo removido para un tamaño de partícula de 1 mm y una cantidad de 5 g de aserrín a diferentes concentraciones.

description: INTRODUCTION: Congenital vascular malformations are entities with a broad spectrum of presentations and variable prognosis. They typically present at a young age and are historically associated with extensive resection surgeries and with high morbidity. This study aims to evaluate the results of arteriovenous malformations (AVMs) embolization as a first-line approach in lesions which are not suitable for surgical resection. METHODS: A retrospective analysis of the clinical records of patients with infiltrative arteriovenous malformations who underwent embolization at our center between 2019 and 2021 was performed. The Schobinger Classification was applied to categorize the clinical stage. Angiographic findings were reported according to the Yakes classification. The decrease in the Schöbinger grade after treatment, the need for reintervention and the associated complications were the main outcomes. A descriptive statistical analysis was performed. RESULTS: Nine patients undergoing embolization of infiltrative arteriovenous malformations were evaluated, accounting for a total of seventeen interventions. There was a preponderance of females (n=6; 66.7%) and the mean age of referral to the Vascular Surgery consultation and the first treatment was 16.8 (±12.9) and 20.9 (± 14.5) years, respectively. All patients were in stage II (n=4; 44.4%) or III (n=5; 55.6%) of Schöbinger. The angiographic pattern of the AVMs was classified according to the Yakes Classification, which guided the approach. Yakes type IIa was found most frequently (n=6; 55.6%), followed by type IV (n=2; 22.2%) and type IIb (n=1; 1.1%). Patients underwent AVM embolization via transarterial, transvenous or direct nidus puncture with sclerosing agents, liquid embolizers, microparticles and microcoils, separately or in combination. The median number of interventions per patient was 1 (1 – 5) and Yakes type IV appears to be associated with a higher rate of reintervention. Reduction of the Schöbinger stage was achieved in 7 (77.8%) patients with clinical resolution in 3 (33.3%). Tissue necrosis was the only complication reported in this series (n=2; 11,8%). CONCLUSION: The endovascular approach of arteriovenous malformations through nidus and/or afferent/ efferent embolization requires a detailed angiographic characterization but seems to be an effective strategy with a low risk of complications. The Yakes classification, can be useful both in guiding the approach and inpredicting the need for reintervention.
