Quality Assessment and Practical Interpretation of the Wave Parameters Estimated by HF Radars in NW Spain

High-frequency (HF) radars are efficient tools for measuring vast areas and gathering ocean parameters in real-time. However, the accuracy of their wave estimates is under analysis. This paper presents a new methodology for analyzing and validating the wave data estimated by two CODAR SeaSonde radars located on the Galician coast (NW Spain). Approximately one and a half years of wave data (January, 2014–April, 2015) were obtained for ten range cells employing two different sampling times used by the radar software. The resulting data were screened by an updated method, and their abundance and quality were described for each radar range cell and different wave regime; the latter were defined using the spectral significant wave height (Hm0) and mean wave direction (Dm) estimated by two buoys and three SIMAR points (SImulación MARina in Spanish, from the wave reanalysis model by Puertos del Estado (PdE)). The correlation between the results and the particularities of the different sea states (broadband or bimodal), the wind and the operation of the devices are discussed. Most HF radar wave parameters’ errors occur for waves from the NNE and higher than 6 m. The best agreement between the Vilán radar and the Vilano-Sisargas buoy wave data was obtained for the dominant wave regime (from the northwest) and the southwest wave regime. However, relevant contradictions regarding wave direction were detected. The possibilities of reducing the wave parameters’ processing time by one hour and increasing the numbers of range cells of the radars have been validatedThis research was funded by Interreg Atlantic Area project MyCOAST (EAPA 285/2016) and INTERREG V-A Spain-Portugal (POCTEP) project RADAR_ON_RAIA co-funded by the European Regional Development Fund (ERDF) (EU).

Experimental and DFT Study of the [AuAr(AsPh3)]-Catalyzed cis/trans Isomerization of [PdAr2(AsPh3)2] (Ar = C6F5 or C6Cl2F3): Alternative Mechanisms and Its Switch upon Pt for Pd Substitution

Producción CientíficaThe aryl transmetalation processes between cis-[PdRf2(AsPh3)2] (Rf = C6Cl2F3) and [AuPf(AsPh3)] (Pf = C6F5) has been studied experimentally and by DFT calculations. Aryl exchange with or without isomerization of the Pd geometry occurs by ligand displacement of one AsPh3 ligand by an [AuAr(AsPh3)] molecule, which coordinates using the Au–Ar bond electron density, followed or not by a second switch to the next aryl (Ar) group. The transition states are bridged Ar–Au(AsPh3)–Ar′ structures with fairly planar geometries. Alternatively, a direct switch of the Au(AsPh3) fragment to either cis or trans Ar groups on Pd can be achieved from a square-pyramidal [(AsPh3)Au-PdAr3(AsPh3)] intermediate or transition state. The later pathway is less favorable for the case studied (M = Pd), but it is preferred for the same chemical system with M = Pt. The study provides some clues on exchanges that can be relevant in organic syntheses catalyzed by bimetallic systems.Ministerio de Economía, Industria y Competitividad (projects CTQ2016-80913-P and CTQ2017-89217-P)Junta de Castilla y León (projects VA051P17 and VA062G18)Xunta de Galicia (Consolidación GRC ED431C2017/61 from DXPCTSUG; ED-431G/02-FEDER “Unha maneira de facer Europa” to CINBIO, a Galician research center 2016−2019

Magneto-caloric effect in the pseudo-binary intermetallic YPrFe17 compound

We have synthesized the intermetallic YPrFe17 compound by arc-melting. X-ray and neutron powder diffraction show that the crystal structure is rhombohedral with View the MathML source space group (Th2Zn17-type). The investigated compound exhibits a broad isothermal magnetic entropy change {\Delta}SM(T) associated with the ferro-to-paramagnetic phase transition (TC \approx 290 K). The |{\Delta}SM| (\approx 2.3 J kg-1 K-1) and the relative cooling power (\approx 100 J kg-1) have been calculated for applied magnetic field changes up to 1.5 T. A single master curve for {\Delta}SM under different values of the magnetic field change can be obtained by a rescaling of the temperature axis. The results are compared and discussed in terms of the magneto-caloric effect in the isostructural R2Fe17 (R = Y, Pr and Nd) binary intermetallic alloys.Comment: Preprint, 5 pages (postprint), 4 figures, regular pape

However, the role of SWI/SNF in acute myeloid leukemia is poorly understood. To date, SWI/SNF complexes are thought to be oncogenic in AML or, at least, necessary to support leuke‑ mogenesis. However, mutation patterns in SWI/SNF genes in AML are consistent with a tumor suppressor role. Here, we study the SWI/SNF subunit BCL7A, which has been found to be recurrently mutated in lymphomas, but whose role in acute myeloid malignancies is currently unknown. Methods Data mining and bioinformatic approaches were used to study the mutational status of BCL7A and the correlation between BCL7A expression and promoter hypermethylation. Methylation‑specific PCR, bisulfite sequenc‑ ing, and 5‑aza‑2’‑deoxycytidine treatment assays were used to determine if BCL7A expression was silenced due to promoter hypermethylation. Cell competition assays after BCL7A expression restoration were used to assess the role of BCL7A in AML cell line models. Differential expression analysis was performed to determine pathways and genes altered after BCL7A expression restoration. To establish the role of BCL7A in tumor development in vivo, tumor growth was compared between BCL7A‑expressing and non‑expressing mouse xenografts using in vivo fluorescence imaging. Results BCL7A expression was inversely correlated with promoter methylation in three external cohorts: TCGA‑LAML (N = 160), TARGET‑AML (N = 188), and Glass et al. (2017) (N = 111). The AML‑derived cell line NB4 silenced the BCL7A expression via promoter hypermethylation. Ectopic BCL7A expression in AML cells decreased their competitive ability compared to control cells. Additionally, restoration of BCL7A expression reduced tumor growth in an NB4 mouse xenograft model. Also, differential expression analysis found that BCL7A restoration altered cell cycle pathways and modified significantly the expression of genes like HMGCS1, H1-0, and IRF7 which can help to explain its tumor sup‑ pressor role in AML. Conclusions BCL7A expression is silenced in AML by promoter methylation. In addition, restoration of BCL7A expres‑ sion exerts tumor suppressor activity in AML cell lines and xenograft models.Consejería de Universidad, Investigación e Innovación de la Junta de Andalucía and FEDER (P20‑00688)Ministry of Science and Innovation of Spain (grant PID2021‑126111OB‑I00)Junta de Andalucía (grants PIGE‑0440–2019, PI‑0135–2020)University of Granada (B‑CTS‑126‑UGR18, B‑CTS‑480‑UGR20, E‑CTS‑304‑UGR20)Spanish Association for Cancer Research (LABORATORY‑AECC‑2018)Spanish Ministry of Science, Innovation and Universities FPU18/03709, FPU17/00067, FPU19/0057

Ambient Intelligence Systems for Personalized Sport Training

Several research programs are tackling the use of Wireless Sensor Networks (WSN) at specific fields, such as e-Health, e-Inclusion or e-Sport. This is the case of the project “Ambient Intelligence Systems Support for Athletes with Specific Profiles”, which intends to assist athletes in their training. In this paper, the main developments and outcomes from this project are described. The architecture of the system comprises a WSN deployed in the training area which provides communication with athletes’ mobile equipments, performs location tasks, and harvests environmental data (wind speed, temperature, etc.). Athletes are equipped with a monitoring unit which obtains data from their training (pulse, speed, etc.). Besides, a decision engine combines these real-time data together with static information about the training field, and from the athlete, to direct athletes’ training to fulfill some specific goal. A prototype is presented in this work for a cross country running scenario, where the objective is to maintain the heart rate (HR) of the runner in a target range. For each track, the environmental conditions (temperature of the next track), the current athlete condition (HR), and the intrinsic difficulty of the track (slopes) influence the performance of the athlete. The decision engine, implemented by means of (m; s)-splines interpolation, estimates the future HR and selects the best track in each fork of the circuit. This method achieves a success ratio in the order of 80%. Indeed, results demonstrate that if environmental information is not take into account to derive training orders, the success ratio is reduced notably.Ministerio de Educación y Ciencia; DEP2006-56158-C03-01/02/03Ministerio de Educación y Ciencia; TEC2007-67966 -01/02/TCM CON-PARTE-1/2Ministerio de Industria, Turismo y Comercio ; TSI-020301-2008-16 ELISAMinisterio de Industria, Turismo y Comercio ; TSI-020301-2008-2 PIRAmID

San Adrian: un nuevo yacimiento de la Edad del Bronce en el Norte de la Peninsula Iberica

Bronze Age studies carried out in the Cantabrian Region have traditionally focused on prestige goods and funerary contexts. As a result of this, the lack of information about daily activities, subsistence strategies, and human settlement on a regional scale is evident in the state of art. However, current research has achieved new discoveries in recent years, allowing a reconstruction of some aspects of the economic structure, settlements, material culture and the palaeoenvironment during the Bronze Age. Indeed, besides the funerary practices discovered in 1983 in San Adrian (Parztuergo Nagusia, Gipuzkoa), research has now revealed the presence of Upper Palaeolithic and Early Bronze Age occupations. This paper presents a first characterization of the retrieved evidence and a preliminary evaluation of the archaeological site and its environment. San Adrian is a tunnel-shaped cave located at 1,000 meters a.s.l. in the Aizkorri mountain range, opening a passage beneath the Atlantic-Mediterranean watershed in northern Iberia. The strategic character of this mountain site is demonstrated by the presence of Upper Palaeolithic and Bronze Age occupations, and by the construction of a road passing through it and the fortification of both its entrances in the Middle Ages. The aim of the archaeological survey started in 2008 was to identify, describe and evaluate the heritage potential of the cave, because previous fieldwork had only managed to make surface finds in the side galleries, including a medieval hoard and Bronze Age human remains. The work carried out by our research group at San Adrian includes a series of test pits and the excavation of an area nine square metres in size following stratigraphic criteria. In the current state, we identified at least two contexts corresponding to Late Upper Palaeolithic and Bronze Age occupations in the cave. Fieldwork included the sieving and flotation of sediment and the collection of samples for different types of analysis: palynology, carpology, sedimentology, and radiocarbon dating. The evidence is being studied by a multidisciplinary team according to expertise requirements for each topic: palaeobotany and environment, archaeozoology, sedimentology, geology, physical anthropology, prehistoric industries (lithics, pottery and bone) and archaeological and historical documentation. Because of its recent discovery, Upper Palaeolithic evidence remains still under study, but first results on Bronze Age layers can be presented. The ongoing archaeobotanical and archaeozoological studies reveal the exploitation of domestic plants and fauna complemented by hunting and foraging of wild species. At the same time, the archaeological artefacts and their production sequences show the exploitation of nearby resources on both sides of the mountain range, while prestige goods are absent. This evidence is also used to estimate the regularity of cave occupations and to propose a model of seasonal exploitation of the mountain environment. The results obtained reveal the exploitation of resources from both the Mediterranean and Atlantic basins, and contribute towards an understanding of the daily activities of Bronze Age societies. In addition, the evidence shows the exchange and circulation of quotidian products between the Cantabrian region and inland Iberia in other networks than those of prestige goods

A large, ten-generation family with autosomal dominant preaxial polydactyly/triphalangeal thumb: Historical, clinical, genealogical, and molecular studies

We present a large, ten-generation family of 273 individuals with 84 people having preaxial polydactyly/triphalangeal thumb due to a pathogenic variant in the zone of polarizing activity regulatory sequence (ZRS) within the exon 5 of LMBR1. The causative change maps to position 396 of the ZRS, located at position c.423 + 4909C > T (chr7:156791480; hg38; LMBR1 ENST00000353442.10; rs606231153 NG_009240.2) in the intron 5 of LMBR1. The first affected individual with the disorder was traced back to mid-1700, when some settlers and workers established in Cervera de Buitrago, a small village about 82 km North to Madrid. Clinical and radiological studies of most of the affected members have been performed for 42 years (follow-up of the family by LFGA). Molecular studies have confirmed a pathogenic variant in the ZRS that segregates in this family. To the best of our knowledge, this is the largest family with preaxial polydactyly/triphalangeal thumb reported so far.Instituto de Salud Carlos III, Grant/Award Number: PI20/0105

Comprehensive Analysis of SWI/SNF Inactivation in Lung Adenocarcinoma Cell Models

Simple Summary: Mammalian SWI/SNF complexes regulate gene expression by reorganizing the way DNA is packaged into chromatin. SWI/SNF subunits are recurrently altered in tumors at multiple levels, including DNA mutations as well as alteration of the levels of RNA and protein. Cancer cell lines are often used to study SWI/SNF function, but their patterns of SWI/SNF alterations can be complex. Here, we present a comprehensive characterization of DNA mutations and RNA and protein expression of SWI/SNF members in 38 lung adenocarcinoma (LUAD) cell lines. We show that over 85% of our cell lines harbored at least one alteration in one SWI/SNF subunit. In addition, over 75% of our cell lines lacked expression of at least one SWI/SNF subunit at the protein level. Our catalog will help researchers choose an appropriate cell line model to study SWI/SNF function in LUAD. Abstract: Mammalian SWI/SNF (SWitch/Sucrose Non-Fermentable) complexes are ATP-dependent chromatin remodelers whose subunits have emerged among the most frequently mutated genes in cancer. Studying SWI/SNF function in cancer cell line models has unveiled vulnerabilities in SWI/SNF-mutant tumors that can lead to the discovery of new therapeutic drugs. However, choosing an appropriate cancer cell line model for SWI/SNF functional studies can be challenging because SWI/SNF subunits are frequently altered in cancer by various mechanisms, including genetic alterations and post-transcriptional mechanisms. In this work, we combined genomic, transcriptomic, and proteomic approaches to study the mutational status and the expression levels of the SWI/SNF subunits in a panel of 38 lung adenocarcinoma (LUAD) cell lines. We found that the SWI/SNF complex was mutated in more than 76% of our LUAD cell lines and there was a high variability in the expression of the di erent SWI/SNF subunits. These results underline the importance of the SWI/SNF complex as a tumor suppressor in LUAD and the di culties in defining altered and unaltered cell models for the SWI/SNF complex. These findings will assist researchers in choosing the most suitable cellular models for their studies of SWI/SNF to bring all of its potential to the development of novel therapeutic applications.Ministry of Economy of Spain SAF2015-67919-RJunta de Andalucía CS2016-3 P12-BIO1655 PIGE-0440-2019 Pl-0245-2017 PI-0135-2020University of Granada PPJIA2019-0 B-CTS-126-UGR18International Association for the Study of Lung Cancer (IASLC)Spanish Association for Cancer Research (LAB-AECC)PhD "La Caixa Foundation" LCF/BQ/DE15/10360019"Fundacion Benefica Anticancer Santa Candida y San Francisco Javier" predoctoral fellowshipEuropean Commission 837897Spanish Ministry of Education, Culture and Sports FPU fellowship FPU17/00067 FPU17/01258 FPU18/03709PhD FPI-fellowship BES-2013-064596Fundación Científica de la Asociación Española Contra el Cáncer GCB14-2170Fundación Ramon ArecesInstituto de Salud Carlos III-Fondo de Investigación Sanitaria-Fondo Europeo de Desarrollo Regional `Una manera de hacer Europa' (FEDER) PI19/0009

Objetivo principal: poner a disposición de los alumnos de segundo ciclo del Grado de Periodismo un espacio de coworking en condiciones adecuadas así como docentes que les tutelen para que puedan afrontar sus ideas y proyectarlas hacia el mercado de la Comunicación, en el que puedan desarrollar sus proyectos periodísticos y lograr la creación de una micro-pyme informativa y/o de comunicación. Objetivos específicos: a) Diseñar un marco integral de conocimientos a partir de las competencias periodísticas aprendidos en la titulación de periodismo: la empresa informativa, la estructura, la tecnología, la dirección y gestión periodística y de medios, para acercar a los estudiantes al mundo empresarial. b) Facilitar la salida al mercado laboral, empresarial y en Comunicación a cuantas ideas de negocio se valoren como posibles y se puedan gestionar desde estos espacios de trabajo colaborativo, mediante la tutorización y la mentoría. En cuanto a la metodología aplicada, se trata de evaluar y proyectar ideas creativas previas a su lanzamiento al mercado, a partir de una personalidad jurídica concreta y presumible (viabilidad societaria), durante el cuatrimestre de trabajo (fase de recuperación de datos) a partir de dos grupos (muestra total de unos 132 alumnos) divididos en 18 equipos (17 presenciales y uno virtual) organizados a partir de un proyecto de innovación docente. Se les explica el contenido del proyecto y las razones de llevarlo a cabo, tras lo cual sólo 16 alumnos han decidido no participar, por lo que el total de alumnos participantes ha sido de 116. Los espacios de desarrollo metodológico se sitúan en el marco de las clases de 4º curso del Grado de Periodismo, asignatura de “Dirección y Gestión de Empresas Periodísticas”, grupos A y C, durante el 2ª Cuatrimestre del curso 2017-2018 (enero-mayo) y termina con una presentación de cada proyecto a la finalización del periodo lectivo. Destacar como resultados más notables que de los 18 equipos que todos son proyectos nativos digitales y que internet es la red por excelencia que les acoge y les permite distribuir sus productos a partir de contenidos periodísticos de información, bien generalista o de diferentes temáticas que a su vez se van especializando. Seis de estos proyectos se basan en la información general y otros cuatro establecen la información cultural como el valor fundamental sobre el que descansa su idea emprendedora. Ocho proyectos se distinguen por ser considerados temáticos con especializaciones muy diversas: el fútbol sala y la hípica (en el marco deportivo); la arquitectura; la información universitaria; videojuegos y tecnología; los productos lácteos (alimentación); sobre la tercera edad, y sobre el negocio de las “bodas… y divorcios”. Se observa una clara tendencia para su oportunidad de negocio y encuentran razones de mercado para un lanzamiento a corto – medio plazo. Uno de estos proyectos está residente en Tetuán Valley
