Hemobilia due to cystic artery pseudoaneurysm: A rare late complication of laparoscopic cholecystectomy

We discuss a patient with late presentation of hemobilia following cholecystectomy, which is unusual because pseudoaneurysm caused by vascular injury during surgery typically presents soon after surgery. Endoscopic retrograde cholangiopancreatography revealed a large blood clot arising from the biliary orifice with subsequent computed tomography angiography diagnosing a large pseudoaneurysm in the region of the cystic artery adjacent to the cholecystectomy clips. Embolization was performed via direct percutaneous puncture of the pseudoaneurysm

Design and Performance Analysis of a Non-Standard EPICS Fast Controller

The large scientific projects present new technological challenges, such as the distributed control over a communication network. In particular, the middleware EPICS is the most extended communication standard in particle accelerators. The integration of modern control architectures in these EPICS networks is becoming common, as for example for the PXI/PXIe and xTCA hardware alternatives. In this work, a different integration procedure for PXIe real time controllers from National Instruments is proposed, using LabVIEW as the design tool. This methodology is considered and its performance is analyzed by means of a set of laboratory experiments. This control architecture is proposed for achieving the implementation requirements of the fast controllers, which need an important amount of computational power and signal processing capability, with a tight real-time demand. The present work studies the advantages and drawbacks of this methodology and presents its comprehensive evaluation by means of a laboratory test bench, designed for the application of systematic tests. These tests compare the proposed fast controller performance with a similar system implemented using an standard EPICS IOC provided by the CODAC system.Comment: This is the extended version of the Conference Record presented in the IEEE Real-Time Conference 2014, Nara, Japan.

Self-Propelled Soft Everting Toroidal Robot for Navigation and Climbing in Confined Spaces

There are many spaces inaccessible to humans where robots could help deliver sensors and equipment. Many of these spaces contain three-dimensional passageways and uneven terrain that pose challenges for robot design and control. Everting toroidal robots, which move via simultaneous eversion and inversion of their body material, are promising for navigation in these types of spaces. We present a novel soft everting toroidal robot that propels itself using a motorized device inside an air-filled membrane. Our robot requires only a single control signal to move, can conform to its environment, and can climb vertically with a motor torque that is independent of the force used to brace the robot against its environment. We derive and validate models of the forces involved in its motion, and we demonstrate the robot's ability to navigate a maze and climb a pipe.Comment: 7 pages and 8 figures.

Effect of sex and carcass weight on carcass traits and meat quality in goat kids of Cabrito Transmontano

This work aims to study sex and carcass weight effect on carcass and meat quality characteristics of a protected designation of origin (PDO) product, cabrito Transmontano. A total of 60 animals with carcass weight ranging between 4 and 8 kg were used. Carcass conformation, commercial joints, tissues measurements and proportions, carcass pH, meat colour and meat texture were evaluated. Sex had a significant effect on carcass composition and males had higher bone and less intermuscular fat and kidney knob and channel fat proportion than females. Males showed better carcass compactness as a result of a higher hot carcass weight (HCW)/carcass length (K) ratio. Carcass weight significantly affected carcass joint proportion. As the carcass weight increased there was an increase in carcass linear measurements, carcass compactness, chump and breast proportions, fat depots and tissues measurements and a decrease in leg, shoulder, fore ribs and bone proportion. Increasing carcass weight meat became less luminous with more vivid red colour as a result of a progressive brightness reduction and a redness increment. Consequently hue and chroma parameters went through a significant increase and decrease, respectively. A significant effect of carcass weight was found in longissimus dorsi muscle measurements, and muscle area increased as well the subcutaneous fat thickness. Carcass weight also had a significant effect on meat texture measured by Warner-Bratzler shear force, which reduced its value as carcass weight increased. The meat quality parameters studied could be a tool to identify and characterize a product with PDO as cabrito Transmonstan

Subjective measurements of fat cover and kidney knob and channel fat for predicting leg and rib tissue composition of Blanca Celtibérica kids.

CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of leg and rib tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97% of the variation in muscle weight was accounted for by variation in CCW and the inclusion of KKCF amount scored from 1 to 9 improve the precision of the prediction 1%, reducing the RSD in 11,8%. The inclusion of KKCF amount (scored 1-3) did not improve the precision of the rib muscle composition but reduced the RSD in 6,2%. In relation to bone composition of both joints, 95% and 73% of the variation of the leg and rib bone weight, respectively were accounted for by variation on CCW. The 87 and 85% of the leg and rib fat weight variation were accounted for by variation in CCW associated with fat score (1-15) and KKCF amount (1-3) with a RSD of 17 and 32,4 g, respectively. El peso canal fría, grado de engrasamiento con dos escalas de (1-5) y de (1-15) puntos y cantidad de grasa pélvico renal con dos escalas de puntuación (1-3) y (1-9) fueron utilizados como predictores de la composición tisular de la pierna y costillar de 31 cabritos de raza Blanca Celtibérica, con una media de peso canal fría de 6,9± 2,1 Kg. La variación del peso canal fría explicó el 97% de la variación en el peso del músculo de ambas piezas y la entrada en el modelo de la cantidad de grasa pélvico renal (1-9) incrementó un 1% la precisión de la estimación del peso del músculo del costillar con una reducción asociada del RSD de un 11,8%. A su vez la entrada en la ecuación de predicción del peso del músculo del costillar, de la cantidad de grasa pélvico renal (1-3) no mejoró la precisión de la estimación, pero sí que supuso un 6,2% de reducción del RSD. Respecto a la predicción del peso del hueso en ambas piezas, el 95% de la variación en el peso del mismo en la pierna, fue explicado por la variación en el peso de la canal fría, mientras que la variación en el peso de esta misma variable tan solo explicó el 73% de la variación en el peso del hueso del costillar. Finalmente, la variación del peso canal fría, engrasamiento (1-15) y cantidad de grasa pélvico renal (1-3) explicó el 87 y 85% de la variación en el peso de la grasa total de la pierna y costillar con unas RSD asociadas de 17,0 y 32,4 g, respectivamente

Medidas subjetivas del grado de engrasamiento y cantidad de grasa pélvico renal para predecir la composición tisular de la espalda, cuello y bajos de cabritos Blanco Celtibéricos

CCW, the assess of FC on two scores (1-5) and (1-15) and the assess of KKCF amount on two scores (1-3) and (1-9) were used as predictors of shoulder, neck and flank plus breast tissue composition of 31 Blanca Celtibérica kids, with an average CCW of 6,9± 2,1 Kg. Proportionately 97, 91 and 92% of the variation in muscle weight of shoulder, neck and flank plus breast, respectively were accounted for by variation in CCW. The variation in CCW also explained 96, 49 and 86% of the variation of shoulder, neck and flank plus breast bone tissue composition. The inclusion in the prediction equation for neck bone weight of FC (1-15), increase the precision in 7% and reduced the RSD in 5,7%. Finally the variation in CCW and FC (1-15) explained 87, 76 and 90% of the variation in fat weight of shoulder, neck and flank plus breast, respectively. Nevertheless the inclusion of KKCF amount (1-3) in the prediction equations of fat weight of shoulder and flank plus breast increase the precision in 2% and reduced the RSD in 6,1 and 10,2%, respectively. El peso canal fría, grado de engrasamiento con dos escalas de (1-5) y de (1-15) puntos y cantidad de grasa pélvico renal con dos escalas de puntuación (1-3) y (1-9) fueron utilizados como predictores de la composición tisular de la espalda, cuello y bajos de 31 cabritos de raza Blanca Celtibérica, con una media de peso canal fría de 6,9± 2,1 Kg. La variación del peso canal fría explicó el 97, 91 y 92% de la variación en el peso del músculo de la espalda, cuello y bajos respectivamente. Así mismo, la variación del peso canal fría explicó el 96, 49 y 86% de la variación en el peso del hueso de las mismas piezas y en el mismo orden. No obstante la entrada en la ecuación de predicción del peso del hueso del cuello, del engrasamiento (1-15) mejoró la precisión de la estimación en 7 puntos porcentuales, con una reducción del RSD asociado del 5,7%.

Phononic crystal with free-form waveguiding and broadband attenuation

Waveguiding is highly desirable for multiple applications but is challenging to achieve in wide continuous frequency ranges. In this work, we developed a three-dimensional phononic crystal with broadband waveguiding functionality. Waveguiding is achieved by combining two types of unit cells with different wave scattering features to create an arbitrary-curved defect path. The unit cell design is governed by contradictory requirements to induce narrow- and broad-band wave attenuation along the path and within the phononic medium, respectively. This is achieved by modulating structural parameters to activate Bragg's scattering, local resonances and inertial amplification mechanism and interplay between them. We demonstrated numerically and experimentally the waveguiding with strong wave localization and confinement in additively manufactured three-dimensional structures along straight, angle- and arbitrary-curved paths. This work opens new perspectives for the practical utilization of phononic crystals in ultrasonic sensors, medical devices, and acoustic energy harvesters
