El Instituto de Derecho Canónico del Estudio General de Navarra
No full textEl autor, que fue el primer director del Instituto de Derecho Canónico erigido en el Estudio General de Navarra en 1959, ofrece un testimonio directo y documentado de las circunstancias que rodearon los orígenes del centro. En 1957 San Josemaría Escrivá, fundador del Opus Dei y de la Universidad de Navarra, impulsó el proyecto, dentro de un plan de conjunto orientado a promover el desarrollo institucional del Estudio General de Navarra, de crear una Facultad de Derecho Canónico. Un papel destacado en el desarrollo del proceso correspondió a D. Álvaro del Portillo, entonces Secretario General del Opus Dei, a quien San Josemaría encargó gestiones bien determinadas ante el Nuncio y los obispos de España. El centro fue erigido en junio de 1959, mediante la fórmula de la agregación al Instituto Utriusque Iuris de la Pontificia Universidad Lateranense. El 25 de octubre de 1960 el Instituto pasó a ser Facultad de Derecho Canónico.The author, who was the first director of the Institute of Canon Law established in the Estudio General de Navarra in 1959, gives a direct, documented account of the circumstances surrounding the origin of the center. In 1957, St. Josemaría Escrivá, founder of Opus Dei and the University of Navarra, initiated the project as part of an overall plan to promote the institutional development of the Estudio General de Navarra by establishing a School of Canon Law. An important role in the development process was played by D. Álvaro del Portillo, the former Secretary General of Opus Dei, who was com- missioned by St. Josemaría to address a number of specific issues with the Nuncio and the bishops of Spain. The center was established in June 1959 by means of a formula of aggregation to the Institute Utriusque Iuris of the Lateran Pontifical University. On 25 October 25 1960, the Institute became the School of Canon Law
Classical and new insights into the methodology for characterizing adsorbents and metal catalysts by chemical adsorption
No full textThe adsorption phenomenon has been used extensively to achieve and explain solid-state reactions, control contamination, and purify liquids and gases. This process implies the use of a porous medium or a material with specific adsorption centers where the interactions with the reagents occur. Determination of the properties of adsorbent or catalyst materials that do not contain specific adsorption sites by physical gas adsorption is a well-established procedure in most research and quality-control laboratories. However, characterizing the specific centers by selective adsorption—chemisorption—remains an open question for discussion and study. The specific centers involved are often acidic/basic and metallic; in most cases, reagents are adsorbed and desorbed in these centers, whose determination allows controlling the processes and comparing the materials. The techniques and procedures presented herein facilitate the evaluation and the qualitative and quantitative determination of the surface properties of the materials using chemisorption processes for metallic and acidic/basic sites. The aim of this work is to review these techniques and procedures, including the updates published by several researchers, who mostly strive to explain the results of bifunctional metallic and acid–base catalytic behavior.The author is grateful for financial support from the Spanish Ministry of Science and Innovation (AEI/MINECO) and Government of Navarra through projects PID2020-112656RB-C21 and 0011-3673-2021-000004.

On generalisations of conciseness
No full textBased on the notions of conciseness and semiconciseness, we
show that these properties are not equivalent by proving that a word
originally presented by Ol’shanskii is semiconcise but not concise. We
further establish that every 1/m-concise word is semiconcise by proving
that when the group-word w takes finitely many values in G, the iterated
commutator subgroup [w(G), G, (m) ...,G] is finite for some m ∈ N if and
only if [w(G), G] is finite.The author is supported by the project PID2020-117281GB-I00 (Spanish Government, partially funded with ERDF) and by the research group 244 Álgebra. Aplicaciones (Public University of Navarra). Open Access funding provided by Universidad Publica de Navarra
Advancing ASL kidney image registration: a tailored pipeline with VoxelMorph
No full textIn clinical renal assessment, image registration plays a pivotal role, as patient movement during data acquisition can
significantly impede image post-processing and the accurate estimation of hemodynamic parameters. This study introduces
a deep learning-based image registration framework specifically for arterial spin labeling (ASL) imaging. ASL is a
magnetic resonance imaging technique that modifies the longitudinal magnetization of blood perfusing the kidney using a
series of radiofrequency pulses combined with slice-selective gradients. After tagging the arterial blood, label images are
captured following a delay, allowing the tagged blood bolus to enter the renal tissue, while control images are acquired
without tagging the arterial spins. Given that perfusion maps are generated at the pixel level by subtracting control images
from label images and considering the relatively small signal intensity difference, precise alignment of these images is
crucial to minimize motion artefacts and prevent significant errors in perfusion calculations. Moreover, due to the extended
ASL acquisition times and the anatomical location of the kidneys, renal images are often susceptible to pulsation,
peristalsis, and breathing motion. These motion-induced noises and other instabilities can adversely affect ASL imaging
outcomes, making image registration essential. However, research on renal MRI registration, particularly with respect to
learning-based techniques, remains limited, with even less focus on renal ASL. Our study proposes a learning-based image
registration approach that builds upon VoxelMorph and introduces groupwise inference as a key enhancement. The dataset
includes 2448 images of transplanted kidneys (TK) and 2456 images of healthy kidneys (HK). We compared the automatic
image registration results with the widely recognized optimization method Elastix. The model’s performance was evaluated using the mean structural similarity index (MSSIM), normalized correlation coefficient (NCC), temporal signal-tonoise ratio (TSNR) of the samples, and the mean cortical signal (CSIM) in perfusion-weighted images, thereby extending
the evaluation beyond traditional similarity-based metrics. Our method achieved superior image registration performance,
with peak NCC (0.987 ± 0.006) and MSSIM (0.869 ± 0.048) values in the kidney region, significantly surpassing Elastix
and the unregistered series (p\ 0.05) on TK and HK datasets. Regularization analysis showed that higher k values (1, 2)
produced smoother deformation fields, while moderate k values (0.5, 0.9) balanced smoothness and detail, maintaining low
non-positive Jacobian percentages (\1%) comparable to Elastix. Additionally, our method improved CSIM by 14.3%
(2.304 ± 1.167) and TSNR by 13.1% (3.888 ± 2.170) in TK, and achieved up to 13.2% (CSIM) and 29.8% (TSNR)
enhancements in HK, demonstrating robustness and improved signal quality across datasets and acquisition techniques.Open access funding provided by Universidad Pública de Navarra.

The Complaynna que si faze Navarra, writed by Pedro de Sada (c. 1464)
No full textEn el presente trabajo se analiza en profundidad un texto literario de tipo elegíaco redactado por el vicecanciller del Príncipe de Viana, Pedro de Sada, hacia 1464, y titulado Complaynna que de sí faze Navarra. El documento fue publicado ya en el año 2001 bajo el título de Elegía patriótica (pues el texto traslucía un evidente sentimiento de pertenencia a Navarra), pero quedaba pendiente aún un análisis en profundidad que permitiese conocer las motivaciones del autor. Para ello se vuelve a analizar ahora el documento en su aspecto formal, se retoman algunos aspectos biográficos del autor, y se muestran algunas de las fuentes que pudieron servirle de inspiración. La figura de Pedro de Sada adquiere un nuevo perfil, como intelectual y político implicado en la búsqueda de una salida al conflicto bélico que asolaba Navarra, y su creación literaria como un amargo lamento, no exento de intencionalidad política, pero ante todo con una decidida voluntad moralista propia de la época.The present study makes an in-depth examination of an elegiac literary text written around 1464 by the Vice-Chancellor to the Prince of Viana, Pedro de Sada. It was titled Complaynna que de sí faze Navarra and was published in 2001 under the title of Elegía patriótica (as the text revealed a clear sentiment of belonging to Navarre), although an in depth analysis was still required to learn of the real motives of the author. The document is analysed here in its formal sense, highlighting certain biographical details of the author and some of the sources that could have been an inspiration to him. The figure of Pedro de Sada takes on a new profile as an intellectual and politician involved in a solution to the military conflict that was engulfing Navarre, and his literary work comes across as a bitter lament with a fair degree of political intent, but above all with a firm moralistic vocation common to the time.Este trabajo se enmarca dentro de las investigaciones desarrolladas en el marco del proyecto ‘Espacios de la memoria. Los Cartularios regios de Navarra: construcción y expresión del poder’, dirigido por la profesora Eloísa Ramírez Vaquero en la Universidad Pública de Navarra, y financiado por el Ministerio de Ciencia e Innovación (Referencia: HAR2010-21725-C03-02)
Dos topónimos de La Vizcaya (Navarra): Guetadar y Sabaiza
No full textThis is the etymological study of two major place names, Guetadar and Sabaiza, in La Vizcaya (Navarra), previously a Basque-speaking area, and one in which the language was lost from use comparatively late on: both names are documented as far back as the 11th and 12th centuries and formally stable (isolated variants: Quetadar, Gueradarr, etc; and Sabaisse, Isabaica, etc.). The author, who does not fully guarantee the reliability of the documentary evidence, seeks etymological support in geographical knowledge of these places, on the assumption that the toponyms concerned are descriptive of topographic realities. For him, they are Basque compounds: Guetadar < ugeta ((h)ur ‘water’ + the suffix denoting abundance –eta), with dar ‘vein of water’, a meaning which has not been recorded up to now (lexicological contribution); and Sabaiza < zabal ‘wide’ + (h)aitz ‘stone, rock’ with the article –a. (The interpretation of the second constituent as a locative suffix –(a)itz, although in theory not impossible, is unacceptable here for semantic reasons).Estudio etimológico de dos topónimos mayores Guetadar y Sabaiza de La Vizcaya (Navarra), área antes vascófona y de tardío romanceamiento: ambos remontables documentalmente hasta los siglos XI-XII y formalmente estables (variantes aisladas: Quetadar, Gueradarr, etc.; Sabaisse, Isabaica, etc.). El autor, que no confiere su plena fiabilidad a los testimonios documentales, busca el apoyo etimológico en el conocimiento geográfico de los referentes, con el supuesto de que los tops. tratados sean descriptivos de las realidades topográficas. Para él, son compuestos vascos: Guetadar < ugeta ((h)ur ‘agua’ + suf. abundancial –eta) más dar ‘vena de agua’, acepción no registrada hasta la fecha (aportación lexicológica); y Sabaiza < zabal ‘ancho’ más (h)aitz ‘piedra, roca’ con art. –a (La interpretación del segundo constituyente como suf. loc. –(a)itz, si bien no imposible en teoría, aquí es inaceptable por razones semánticas).Vizcaya, biak Nafarroan. Zonaldea euskalduna zen eta oso berandu erromantzatu zen. Bi toponimoak XI-XII. mendeetako dokumentazioan azaltzen dira eta oso egonkorrak izan dira (aldaera bakan batzuk: Quetadar, Gueradarr eta abar; Sabaisse, Isabaica eta abar). Egileak ez dio sinesgarritasun osorik eman nahi dokumentu-lekukotasunari, eta laguntza etimologiko bila jotzen du (egileak hipotesi hau defendatu nahi du: toponimoek bertako topografia azaltzen dutela, alegia). Egilearentzat, beraz, euskal konposatuak dira: Guetadar = “ugeta” (“(h)ur” + “eta” atzizki ugaritikoa) + “dar” (ur-beta, orain arte bildu gabe dagoenez, ekarpen lexikologikoa dena) + “a” artikulua; Sabaiza = “zabal” + “(h)aitz” (harria) + “a” artikulua (bigarren elementua “–(a)itz” atzizki lokatibo bezala hartzea teorikoki posible bada ere, ezin da kasu honetan ontzat eman arrazoi semantikoak direla eta)
