IFML-based Model-Driven Front-End Modernization

Since late 90’s the use of web application frameworks has been the default choice to develop software applications inside the web domain. In parallel, Model Driven Web Engineering approaches have been defined and successfully applied to reduce the effort of web application development and reuse, fostering the independence of the implementation technology. A direct result of the success of these approaches is the elaboration of the Interaction Flow Modeling Language (IFML) as an Object Management Group (OMG) standard. However, the real fact is that there is a huge amount of legacy web systems that were developed before MDWE approaches were mainstream. The work presented herein tries to leverage IFML to modernize the front-ends of framework-based legacy web applications. In concrete, a systematic model driven reverse engineering process to generate an IFML representation from such applications is presented

Exploiting the PIR Sensor Analog Behavior as Thermoreceptor: Movement Direction Classification Based on Spiking Neurons

Pyroelectric infrared sensors (PIR) are widely used as infrared (IR) detectors due to their basic implementation, low cost, low power, and performance. Combined with a Fresnel lens, they can be used as a binary detector in applications of presence and motion control. Furthermore, due to their features, they can be used in autonomous intelligent devices or included in robotics applications or sensor networks. In this work, two neural processing architectures are presented: (1) an analog processing approach to achieve the behavior of a presynaptic neuron from a PIR sensor. An analog circuit similar to the leaky integrate and fire model is implemented to be able to generate spiking rates proportional to the IR stimuli received at a PIR sensor. (2) An embedded postsynaptic neuron where a spiking neural network matrix together with an algorithm based on digital processing techniques is introduced. This structure allows connecting a set of sensors to the post-synaptic circuit emulating an optic nerve. As a case study, the entire neural processing approach presented in this paper is applied to optical flow detection considering a four-PIR array as input. The results validate both the spiking approach for an analog sensor presented and the ability to retrieve the analog information sent as spike trains in a simulated optic nerve.Los sensores infrarrojos piroeléctricos (PIR) se utilizan ampliamente como detectores de infrarrojos (IR) debido a su implementación básica, bajo costo, baja potencia y rendimiento. Combinados con una lente Fresnel, se pueden utilizar como detector binario en aplicaciones de control de presencia y movimiento. Además, por sus características, pueden utilizarse en dispositivos inteligentes autónomos o incluirse en aplicaciones de robótica o redes de sensores. En este trabajo, se presentan dos arquitecturas de procesamiento neuronal: (1) un enfoque de procesamiento analógico para lograr el comportamiento de una neurona presináptica a partir de un sensor PIR. Se implementa un circuito analógico similar al modelo de integración y disparo con fugas para poder generar tasas de picos proporcionales a los estímulos IR recibidos en un sensor PIR. (2) Una neurona postsináptica integrada donde se introduce una matriz de red neuronal con picos junto con un algoritmo basado en técnicas de procesamiento digital. Esta estructura permite conectar un conjunto de sensores al circuito postsináptico emulando un nervio óptico. Como estudio de caso, todo el enfoque de procesamiento neuronal presentado en este artículo se aplica a la detección de flujo óptico considerando una matriz de cuatro PIR como entrada. Los resultados validan tanto el enfoque de picos para un sensor analógico presentado como la capacidad de recuperar la información analógica enviada como trenes de picos en un nervio óptico simulado.This research was partially supported by the Spanish grant MINDROB (PID2019-105556GB-C33) and by the CHIST-ERA H2020 grant SMALL (CHIST-ERA-18-ACAI-004)

[ES]Partiendo de obsérvaciones de radiación solar global diaria (G) recibida en Salamanca durante el período 1977-85 sobre una superficie horizontal, y calculando la radiación solar máxima recibida en el límite de la atmósfera (H0), se ha deducido un índice de claridad diario (K=G/H0 ), que indica el grado de transparencia atmosférica.[EN]Using nine years (1977-85) continuous records of daily global solar radiation (G) at Salamanca, and theoretical values of extraterrestrial solar radiation (H0) on a horizontal plane, the ratio of global to extraterrestrial solar radiation is presented (G/H0=K: daily clearness index)

Wild turkey (Meleagris gallopavo mexicana) monitoring: Innovation in sampling and estimator of population density

Objective: To estimate the population of wild turkey (Meleagris gallopavo, mexicana) and its density in ecosystems of its distribution. Design / methodology / approach: A method based on random sampling with a population density estimator was designed. The design was based on the observation of wild turkeys that go to attraction sites (feedlots) of 2,500 m2 (50 X 50 m) counted in 12 hours a day, three consecutive days. For the total of random sites, the criterion of one site for every 300 ha of surface under study was used. The study was carried out on March 1, 2 and 3, 2019 in 3,000 hectares of pine-oak forest, in Monte Escobedo, Zacatecas, Mexico. Observations were made from a fixed point 25 m from each site, from 6:00 a.m. to 6:00 p.m. The attraction sites were located at a random distance within 10 systematically fixed transects in the study area. Results: The results showed a population of 66 turkeys in 3,000 ha, with a density of 0.022 turkeys ha-1. Limitations / implications: The application of the method was useful for the monitoring of wild turkey in the pine-oak forest, showing that it is a method that does not impact the population, that does not require long sampling times, is reliable, low-cost, and easy to carry out. The method is not reliable in ecosystems that do not allow the location of high visibility sites. Findings / conclusions: Considering the distribution of wild turkey in Mexico, the method is a new alternative applicable to population studies of wild turkey.Objective: To estimate the population of wild turkey (Meleagris gallopavo, mexicana) and its density in ecosystems of its distribution.Design / methodology / approach: A method based on random sampling with a population density estimator was designed.

Body composition features in different playing position of professional team indoor players

The aim of the present research was to analyze the body composition (BC) and the differences in BC among different playing position in professional basketball, handball and futsal players. BC was assessed in 70 professional indoor team sport players. Players were divided in 4 groups depending on the playing position: group 1, point guard, center/wings and defense; group 2, shooting guard/small forward, handed and midfielder; group 3, power forward/center, pivot and forward; and group 4 goalkeeper. Significant differences between playing positions in basketball in body mass (BM), height, proteins, minerals and arms, legs and trunk BM were found. In handball, significant differences between center/wings and pivot in BM and muscle mass, and between goalkeepers and handed in percentage of fat were measured. Significant differences were also found in BM of each playing position groups in the three sports and in arms and legs BM in groups 1 and 2, and trunk BM and height in group 2. Group 3 presented significant differences between futsal and basketball in skeletal muscle mass and trunk BM, and between basketball and handball in left leg BM and total BM. In group 4 significant differences in BM, height and trunk and leg BM between futsal and handball were found. BC in indoor team sports depend on the playing position and the sport discipline, the BC being result of the specific game actions of each playing position.Actividad Física y Deport

Use of Veterinary Vaccines for Livestock as a Strategy to Control Foodborne Parasitic Diseases

Foodborne diseases (FBDs) are a major concern worldwide since they are associated with high mortality and morbidity in the human population. Among the causative agents of FBDs, Taenia solium, Echinococcus granulosus, Toxoplasma gondii, Cryptosporidium spp., and Trichinella spiralis are listed in the top global risk ranking of foodborne parasites. One common feature between them is that they affect domestic livestock, encompassing an enormous risk to global food production and human health from farm to fork, infecting animals, and people either directly or indirectly. Several approaches have been employed to control FBDs caused by parasites, including veterinary vaccines for livestock. Veterinary vaccines against foodborne parasites not only improve the animal health by controlling animal infections but also contribute to increase public health by controlling an important source of FBDs. In the present review, we discuss the advances in the development of veterinary vaccines for domestic livestock as a strategy to control foodborne parasitic diseases.Fil: Sander, Valeria Analia.

ACTIVITY PATTERNS OF JAGUAR, PUMA AND THEIR POTENTIAL PREY IN SAN LUIS POTOSI, MEXICO

Jaguars (Panthera onca) and pumas (Puma concolor) are sympatric species in Mexico and have ecological similarities. The understanding of interespecific interactions between these species are important for effective conservation strategies. We studied activity patterns of jaguars, pumas and their potential prey species through camera-trapping photographs obtained by during four seasonsin the Abra-Tanchipa Biosphere Reserve , San Luis Potosí, Mexico. We described activity patterns of 12 terrestrial vertebrate species, the degree of overlap of jaguar and puma activity; and the prey – predator relationship. Both felids showed cathemeral activity and overlapping between their activities. Jaguar activity showed a significant correlation with eight prey species activity. Puma activity was no related with any prey species activity. Activity peaks of both felids suggest that temporal segregation is a strategy which minimizes interspecific encounters allowing the coexistence of several individuals in this small reserve.El jaguar (Panthera onca) y el puma (Puma concolor) en México son especies simpátricas y presentan similitud ecológica. El entendimiento de las interacciones interespecíficas entre estas especies es importante para la elaboración de estrategias efectivas de conservación. Se estudiaron los patrones de actividad del jaguar, el puma y sus presas potenciales, a través del análisis de las fotografías obtenidas en cuatro temporadas de foto-trampeo en la Reserva de la Biosfera Sierra del Abra-Tanchipa (RBSAT), San Luis Potosí, México. Se describieron los patrones de actividad de 12 especies de fauna, el grado de sobreposición en la actividad del jaguar y el puma; y su relación con la actividad de sus presas. Ambos felinos presentaron actividad catemeral con traslape en sus patrones de actividad. La actividad del jaguar está relacionada significativamente con la actividad de ocho especies de presas; la actividad del puma no se relacionó con la actividad de ninguna presa. Los picos de actividad de ambos felinos sugieren que la separación temporal es una estrategia para minimizar los de encuentros interespecíficos que permite la coexistencia de varios individuos en reservas pequeñas

Characteristics of the white-tailed deer hunting exploitation (Odocoileus virginianus) in Chihuahua, Mexico

Objective: To describe the characteristics of the number of hectares (located in the UMAs registered in the state of Chihuahua) used for the white-tailed deer free-range production, the level of exploitation of the species, and its economic value. Design/Methodology/Approach: This study determined the number of Units for the Conservation, Management, and Sustainable Use of Wildlife (UMAs) registered in the state of Chihuahua, where white tailed deer had been exploited since 2015. Forty-three municipalities in the state of Chihuahua, with a total of 159 UMAs, were analyzed. Twenty-three randomly selected UMAs were characterized, taking into account the hectares and the presence of white-tailed deer per municipality. Finally, the exploitation value of the species use per community was established in order to determine its exploitation and economic value. Results: The total area used for the exploitation of the white-tailed deer reaches 1,067,380 hectares. Thirty-two municipalities had potential for the exploitation of white-tailed deer. Thirty-three deer were hunted per season in the 23 UMAs under study, which accounts for a $990,000 Mexican pesos gross income for the state of Chihuahua per season; this exploitation generates a total of 115 temporary jobs for the communities surrounding the 23 UMAs studied. Chihuahua’s UMAs welcome a total of 33 white-tailed deer hunters per season. Hunters pay$30,000 to $34,000 Mexican pesos for each white-tailed deer specimen. Study Limitations/Implications: The study provides an overview of the current state of the UMAs in the state of Chihuahua that have a permit for the white-tailed deer hunting exploitation. Each of the UMAs under study has specific characteristics, including: the services offered, the associated hunting species, and the exploitation populations under an integrated sustainability arrangement. This study does not include the benefits of exploiting associated species, such as the collared peccary (Dicotyles tajacu) and the wild turkey (Meleagris gallopavo). Findings/Conclusions: Based on the number of registered UMAs, 32 out of 40 municipalities use 100% of their registered area for the exploitation of white-tailed deer. The white-tailed deer hunting exploitation increases the profitability and productivity of livestock ranches
