ASPECTOS BIOLÓGICO – PESQUEROS DEL GÉNERO CYNOSCION (PISCES: SCIAENIDAE) EN EL GOLFO DE MONTIJO, PACÍFICO PANAMEÑO

 The size structure, weight and reproductive patterns of five species of corvinas in the genus Cynoscion was determined in the Gulf of Montijo between April of 2003 and March of 2004. Samples were collected at disembarkation sites (Palo Seco) and fishing boats (in the middle and outer parts of the Gulf) using gillnets with an opening of 7,62 cm (Mesh 3) and 8,89 cm (Mesh 3,5). Sampling was performed monthly with a three-day sampling effort per locality per month. At each sampling site, specimens were identified to species, measured, weighted and gonads were extracted, weighted and classified by color and shape. With this information, the stages of gonadal development were established and the Gonadosomatic Index (GSI) was calculated. The total volumes in landings for corvina were obtained through the Dirección de Recursos Marinos y Costeros of the Autoridad Marítima de Panama for years for Palo Seco in years 2002-2003. Also, the total fishing volume from the Gulf of Montijo was obtained from the Contraloría General de la República. Cynoscion squamipinnis and C. phoxocephalus presented continuous reproduction. Maximum reproductive activity occurred between October and March. Reproductive and spawning peaks occurred between October and December as reflected by the GSI behavior. In both species, the size frequencies compared to the minimum reproductive size (L50) indicated that pre-reproductive recruitment occurs before than fishing. For C. albus fishing takes place before the reproductive recruitment takes place because the largest number of individuals are represented in the earlier stages of development. This is reflected by the low GSI. C. reticulatus and C. stolzmanni were poorly represented in the catching. There was no possibility of doing population inference on this species. The peak of reproductive activity coincides with the periods of greatest catch, which can negatively impact the resource. There was an inverse relationship between the maximum volumes of catch vs. the number of fishing boats operating in the area. An increase in the fishing effort resulted in a decrease in the capture of fish in the Gulf of Montijo between 1998 and 2003.  Entre abril de 2003 y marzo de 2004, se determinó la estructura de tallas, pesos y patrones reproductivos de cinco especies de corvinas del género Cynoscion en el Golfo de Montijo. Se realizaron muestreos en puntos de desembarco (Palo Seco) y a bordo de embarcaciones (parte media y externa del Golfo) con el uso de trasmallos de 7.62 cm (malla 3) y 8.89 cm (malla 3.5) de luz de malla. Los muestreos se realizaron mensualmente, con una duración de tres días en cada localidad. En cada zona los ejemplares fueron identificados, medidos, pesados y se les extrajo las gónadas, las cuales fueron pesadas y clasificadas con base a criterios morfocromáticos, lo cual permitió establecer estadios de desarrollo gonadal y calcular el índice gonadosomático (IGS). Se determinaron los volúmenes de captura de corvinas para los años 2002 – 2003 y los volúmenes totales de pesca y cantidad de embarcaciones registradas para el Golfo de Montijo. Cynoscion squamipinnis y C. phoxocephalus presentaron reproducción continua, con máxima actividad entre octubre y marzo, con picos de madurez y desove entre octubre y diciembre, lo cual se ve reflejado en el comportamiento del IGS. En ambas especies la comparación de la frecuencia de tallas capturadas con la talla mínima reproductiva (L50) indica que el reclutamiento reproductivo ocurre antes que el reclutamiento pesquero. Para C. albus el reclutamiento pesquero ocurre antes que el reproductivo, pues la mayor cantidad de individuos capturados se presentaron en fases tempranas del ciclo gonadal, lo que se ve reflejado en bajos valores del IGS. Para C. reticulatus y C. stolzmanni, la poca representatividad en las capturas no permitió hacer inferencias poblacionales. La época de máxima actividad reproductiva coincide con la época de máximos volúmenes de capturas para las corvinas, lo que puede impactar de manera negativa el recurso. El análisis de los volúmenes totales de capturas contra registro de embarcaciones indica una relación inversa, por lo que un aumento en el esfuerzo pesquero reflejó una disminución en los volúmenes de captura para peces en el Golfo de Montijo entre 1998 y 2003

Reappraisal of the 1863 huércal‐overa earthquake (Betic cordillera, se spain) by the analysis of esi‐07 environmental effects and building oriented damage

This work reviews the 1863 Huércal‐Overa earthquake (VI‐VII EMS) based on the environmental seismic intensity scale (ESI‐07) and oriented archaeoseismological building damage. The performed analysis identifies 23 environmental effects (EEEs) and 11 archaeoseismological effects (EAEs), completing a total of 34 intensity data‐points within the intensity zone ≥ VI EMS. The new ESI intensity data quintuplicate the previous intensity data‐points ≥ VI EMS (five localities) for this event. Sixteen of the identified EEEs indicate the occurrence of intensity VII‐VIII within the Almanzora valley, south of Huércal‐Overa, over an area of ca. 12–15 km2. Anomalies in water bodies, slope movements, hydrogeological anomalies, ground cracking, and other effects (gas emissions, tree shaking) are the more diagnostic EEEs—with one of them indicating a local maximum intensity of VIII‐IX ESI‐07 (Alboraija lake). Environmental earthquake damage of intensity ≥ VI covers an area of c. 100 km2, compatible with a VIII ESI intensity event. The spatial distribution of EEEs and EAEs indicates that the zone of Almanzora River Gorge, which was depopulated during the earthquake epoch, was the epicentral area, and compatible with seismotectonic data from active shallow blind thrusting beneath the Almagro Range. The use of ESI data in nearly unpopulated areas help to fill gaps between damaged localities (EMS data) multiplying intensity data‐points, providing a better definition of the intensity zones and offering a geological basis to look for suspect seismic sourcesCGL2015-67169-

Mixed-signal quadratic operators for the feature extraction of neural signals

This paper presents design principles for reusing charge-redistribution SAR ADCs as digital multipliers. This is illustrated with an 8-b fully-differential rail-to-rail SAR ADC/multiplier, designed in a 180 nm HV CMOS technology. This reconfigurability property can be exploited for the extraction of product-related features in neural signals, such as energy content, or for the discrimination of spikes using the Teager operator.Ministerio de Economía y Competitividad TEC2012-33634Office of Naval Research (USA) N0001414135

Evidence of past seisms in Cusco (Peru) and Tzintzuntzan (Mexico): cultural relations

[ENG] (Evidence of ancient seisms in Cusco, Peru and Tzintzuntzan, Mexico and their cultural relations) At first sight the ancient pre-Columbian cultures seem to have had no awareness of seisms. Purhepecha and Andean cultures nevertheless not only show awareness of these, but also similitude between their anti seismic building techniques. This work exposes clear evidence of coseismic ruptures found In Cusco and in Tzintzuntzan-Patzcuaro. More profound research could nevertheless be helpful to reveal sceneries which are for their most part unknown to current generations

Three-dimensional spatial distribution of synapses in the neocortex: A dual-beam electron microscopy study

In the cerebral cortex, most synapses are found in the neuropil, but relatively little is known about their 3-dimensional organization. Using an automated dual-beam electron microscope that combines focused ion beam milling and scanning electron microscopy, we have been able to obtain 10 three-dimensional samples with an average volume of 180 µm(3) from the neuropil of layer III of the young rat somatosensory cortex (hindlimb representation). We have used specific software tools to fully reconstruct 1695 synaptic junctions present in these samples and to accurately quantify the number of synapses per unit volume. These tools also allowed us to determine synapse position and to analyze their spatial distribution using spatial statistical methods. Our results indicate that the distribution of synaptic junctions in the neuropil is nearly random, only constrained by the fact that synapses cannot overlap in space. A theoretical model based on random sequential absorption, which closely reproduces the actual distribution of synapses, is also presented

The AD 1755 Lisbon Earthquake-Tsunami: Seismic source modelling from the analysis of ESI-07 environmental data

This work presents a macroseismic analysis of the AD 1755 Lisbon Earthquake-Tsunami event by means of the combination of intensity data derived from the EMS-98 scale and the ESI-07 scale (Environmental damage). About 600 records of secondary earthquake environmental effects (EEEs) for the whole Spain have been used to define intensities, focused on the SW portion of the Iberian Peninsula. The Spanish data have been complemented with 308 EEEs records from Portugal. The analyses indicate maximum intensities of X EMS-ESI along the Atlantic margin of the Iberian Peninsula with 76 records of Tsunami environmental effects (TEEs). An important amplification (VIII – VII) occurred all along the Guadalquivir basin and the adjacent Betic front at epicentral distances of 300–700 km. In these zones 55 records of ground effects (ground cracks, Liquefactions and slope movements) are catalogued. In the rest of the territory of the Peninsula the most widespread effects were hydrogeological changes with 505 records in Spain and 196 in Portugal (total 701 records) covering all the intensity levels. Increase of flow discharges in springs and elevation of water level in wells was the common groundwater response to seismic shacking, especially in SW Iberia. In this zone water elevation in wells was between 5 and 3 m and persistent increases of discharges long-lasting (several days to two months). Persistent discharges on springs were linked in 143 cases to important SW-NE crustal faults (e.g., Alentejo-Plasencia Fault). From the Intensity distribution the historic seismic scenarios are explored by means of the development of empirical ShakeMaps. These consider the three classical seismic sources proposed for this earthquake: Gorringe Bank (G); Marques de Pombal Fault (M) and Atlantic delamination beneath the Gulf of Cadiz (C). However, individually these seismic sources are too small and unable to generate the resulting seismic scenario depicted by the intensity map developed in this work, with onshore seismic accelerations (PGA) up to 0.82 g. These acceleration values and the great amplification experienced throughout the Guadalquivir basin (0.34–0.52 g) are only possible considering a combination of the three seismic sources (GMC Source) probably related to shallow subduction or lithospheric delamination beneath SW Iberia and the Gulf of Cadiz. This will suggest an NNE-SSW offshore rupture length of 350–360 km with an overall rupture area of c. 84,500 km2 resulting in an event magnitude 8.6 Mw calculated from empirical relationships. The results demonstrate the efficacy of these kind of approaches for better identifying and modelling seismic sources for historical eventsThis work was supported by the Spanish Research Project MINECOFEDER CGL2015-67169-P (QTECSPAIN - USAL).

3D modelling of archaeological structures and deposits as a method of documentation and dissemination: the case of San Esteban Archaeological Site (Murcia, Spain)

[ES] El conjunto arqueológico de San Esteban se localiza en el actual centro urbano de la ciudad de Murcia. Se trata de un amplio espacio de origen andalusí que formaba parte del antiguo arrabal de la Arrixaca, un barrio extramuros que parece conformarse durante el siglo XI y que constituyó una parte importante de la ciudad medieval de Murcia. El proyecto de investigación realizado entre los años 2018 y 2020 en el conjunto arqueológico de San Esteban, bajo el convenio firmado entre la Universidad de Murcia y el Ayuntamiento de Murcia, conllevó una serie de campañas de excavación arqueológica en diferentes puntos de este enclave. Se intervino en cuatro sectores que se mostraban especialmente relevantes desde el punto de vista funcional y de la articulación urbana de este entramado: los edificios conocidos como Recinto I y Recinto II , el oratorio y la maqbara. El proyecto fue concebido desde una perspectiva interdisciplinar, jugando un papel clave la incorporación de nuevas tecnologías en el proceso de documentación de la excavación. La metodología llevada a cabo se basó en los procedimientos fotogramétricos de alta precisión y de seguimiento diacrónico de la intervención arqueológica, teniendo como objetivo la elaboración de un registro gráfico que afectaba tanto al plano bidimensional (2D) como al tridimensional (3D). Para su correcta elaboración se combinó el uso de vehículos aéreos no tripulados (UAV por sus siglas en ingles) y de instrumental topográfico. Como resultado, este registro permitió confeccionar toda una serie de planimetrías vectoriales, ortomosaicos y recursos 3D de cara a su posterior análisis y de divulgación arquitectónica y material de los elementos arqueológicos intervenidos. Este trabajo desarrolla los procedimientos metodológicos llevados a cabo, una serie de propuestas de análisis y los resultados obtenidos en el marco de aplicación de las nuevas tecnologías en el campo de la arqueología.[EN] The research project carried out between 2018 and 2020 at San Esteban archaeological site (Murcia, Spain), under the agreement signed between the University of Murcia and the Ayuntamiento of Murcia, was realized by a series of archaeological excavation campaigns in different parts of this enclave. Of the sectors involved, we have chosen the four most relevant ones: the buildings known as Recinto I and Recinto II, the "Oratory" and the cemetery or Maqbara (Fig. 1). The objectives of the research project were the review and diagnosis of the state of conservation, the interdisciplinary study, the adoption of consolidation measures and the temporary exposure of the sectors involved (Eiroa et al., 2019; 2021). San Esteban archaeological site is located within the current urban centre of the city of Murcia. It is a good example of medieval Islamic urban design in a part of the old suburb of Arrixaca, a neighbourhood outside the walls of the city that seems to have been formed during the eleventh century. The graphic record in archaeology has been an intrinsic part of the discipline since its inception (Caballero, 2006). Photography and archaeological drawing have been the main ways of documenting an archaeological excavation with the double objective of achieving a topographical reconstruction and ordering the material remains by means of a stratigraphic sequence. Photogrammetry has become one of the main techniques in archaeology and is a great support in the topographic and planimetric survey of high precision and graphic representation. The use of drones or unmanned aerial vehicles (UAV) (Korumaz & Y?ld?z, 2021), high-resolution digital cameras and the appropriate software has enabled their application in numerous cases, generating extensive quality records, as can be seen in the field of medieval archaeology (Enríquez et al., 2020; García-Molina, González-Merino, Rodero-Pérez & Carrasco-Hurtado, 2021; Ruiz, Gallego, Peña, Molero & Gómez, 2015) or in the study of medieval buildings. In the fieldwork at San Esteban archaeological site, a series of topographic instruments and photogrammetric software in a 4D sequence have been used, allowing not only the documentation in the plan of the archaeological structures, but also the location of the deposits in a stratified sequence. For the generation of these diachronic three-dimensional models, the Agisoft Metashape software was used, based on the SfM (Structure from Motion) technique of geometric analysis of clusters of pixels from photographic perspectives with different parallaxes. This technique has become an important methodological dynamic in the archaeological record (Maldonado, 2020: 196-203), improving the work of topography in the field of geomatics (Marín, 2020). The results obtained have allowed the creation of a vector plan of the documented structures and the registration through the SfM photogrammetry of elevations (Fig. 6) and of the depositional process of the sectors involved (Charquero, 2016; Semeraro, 2008). As an example of this methodology, a practical case within the building known as Recinto I is highlighted (Fig. 7). This exercise carried out in the Espacio 4 has made it possible to measure the development of the excavation by continuously recording the activity at a specific point of the site. Also, a detailed delimitation of the extension and volumetric shape from the contact surfaces of a stratigraphic unit has been made, reflecting the physical aspects of the deposit itself at a visual level (Fig. 9). It is a method which emphasises the documentation of the depositional process from a three-dimensional and orthophotographic perspective of the strata (Montalvo, Dyrdahl, Cantisani, Fabririis, & Vinci, 2020; Orengo, 2013), allowing greater detail in the delimitation and shape of the excavated stratigraphic units and assemblages, either synchrGonzález Ballesteros, JÁ.; Gómez Carrasco, JG.; Hernández-Robles, A.; Eiroa Rodríguez, JA.
