Envisioning the idea. Creative graphic processes in architecture and concept art

[EN] The research delves into the creative graphic processes of architecture and concept art, a stage of visual development in world-creating industries such as video games and animation. Pre-production strategies such as conceptual drawings, color scripts or miniature sketches are related to study drawings, sequential drawings or serial visions that define the experience and architectural narrative. The suitable coherence between the visual strategies to explore the idea and the communicative purpose could be useful in architectural design as considering experiential and emotional perception. The findings bring to light a visual development methodology based on design analysis.[ES] El artículo establece un paralelismo entre el arte de concepto desarrollado en industrias creadoras de mundos como los videojuegos y la animación y los procesos gráficos creativos de la arquitectura. Se pone en relación estrategias de pre-producción, como los dibujos conceptuales, el guion de color o los bocetos en miniatura, con los dibujos de estudio, los dibujos secuenciales o las visiones seriales que definen la experiencia y la narrativa gráfica arquitectónica. La coherencia entre las distintas estrategias visuales para explorar la idea y el propósito comunicativo podría ser útil en el diseño arquitectónico al considerar cuestiones vinculadas a la percepción experiencial y emocional. Los hallazgos manifiestan una metodología de desarrollo visual basada en el análisis del diseño de la idea.López-Chao, V.; Fernández-Álvarez, AJ. (2023). Visualizar la idea.

Simulations of model magnetorheological fluids in squeeze flow mode

A particle-level simulation methodology is proposed to study the squeeze flow behavior of model magnetorheological (MR) fluids. The simulation algorithm takes into account Brownian motion and local field corrections to magnetic interactions of the particles. Simulation results obtained from using different initial configurations, including one single-particle-width chain per simulation box, random or lattice arrangements of preassembled single-particle-width chains as well as randomly dispersed particle suspensions, are compared with experimental data and predictions of a recently developed microscopic model. The assumption of single-particle-width chain structures in the systems has been shown to generate normal stresses larger than those found in experiments and the micromechanical model. However, much better agreement between the simulation and experimental results have been reached when using random initial configurations in the simulations

Caveolin-1 Modulates Mechanotransduction Responses to Substrate Stiffness through Actin-Dependent Control of YAP

The transcriptional regulator YAP orchestrates many cellular functions, including tissue homeostasis, organ growth control, and tumorigenesis. Mechanical stimuli are a key input to YAP activity, but the mechanisms controlling this regulation remain largely uncharacterized. We show that CAV1 positively modulates the YAP mechanoresponse to substrate stiffness through actin-cytoskeleton-dependent and Hippo-kinase-independent mechanisms. RHO activity is necessary, but not sufficient, for CAV1-dependent mechanoregulation of YAP activity. Systematic quantitative interactomic studies and image-based small interfering RNA (siRNA) screens provide evidence that this actin-dependent regulation is determined by YAP interaction with the 14-3-3 protein YWHAH. Constitutive YAP activation rescued phenotypes associated with CAV1 loss, including defective extracellular matrix (ECM) remodeling. CAV1-mediated control of YAP activity was validated in vivo in a model of pancreatitis-driven acinar-to-ductal metaplasia. We propose that this CAV1-YAP mechanotransduction system controls a significant share of cell programs linked to these two pivotal regulators, with potentially broad physiological and pathological implications. Moreno-Vicente et al. report that CAV1, a key component of PM mechanosensing caveolae, mediates adaptation to ECM rigidity by modulating YAP activity through the control of actin dynamics and phosphorylation-dependent interaction of YAP with the 14-3-3-domain protein YWHAH. Cav1-dependent YAP regulation drives two pathophysiological processes: ECM remodeling and pancreatic ADM. © 2018 The Author

Fractura-luxación posterior de hombro tratada mediante la técnica de McLaughlin

Se presenta un caso de luxación posterior de hombro, con fractura por impactación de la cabeza humeral, ocasionada por crisis convulsivas. Estas lesiones no son fáciles de reconocer en los primeros momentos, y en nuestro caso se precisó de un estudio radiográfico en distintas proyecciones y una TAC. Se realizó tratamiento quirúrgico mediante la técnica original de McLaughlin. A los 7 meses de la intervención el paciente ha recuperado casi totalmente la movilidad en dicho hombro y está libre de dolor.A case of posterior dislocation of the shoulder with locked fracture of the humeral head after a convulsive seizure is reported. At first stages, this type is very difficult to recognize. In our case, a radiographic study in different views and a CT-scan were needed. Surgical treatment were carried out according to McLauglin's original technique. Seven months after surgery the patient had regained almost complete range of shoulder motion and was pain-free

Unreal memories. La imagen colectiva de la arquitectura en redes sociales visuales

[Abstract] Images of architecture spread quickly on visual social networks that gain interest to disseminate and communicate architecture. For this reason, it is a must to diagnose the social construction of the image of architecture, to explore the restrictions and publication formats of the platform, to identify the reaction and dissemination habits in relation to the visual features of photography and to delve into the possibilities and the risks introduced by artificial intelligence systems. The research method follows a cognitive association approach through various graphic case studies on Instagram. The exploratory design to approach the role of the image to communicate architecture in visual social media arises from the concept of the fragment and the biased vision, a division required due to the nature of related image suggestions as a browsing method on Instagram. The findings identify opportunities and action strategies to complement the contents that build the collective image of architecture adapted to the logic of the new scenario.[Resumen] Las imágenes de arquitectura se propagan rápidamente en las redes sociales visuales que ganan interés para difundir y comunicar la arquitectura. Por ello, es imprescindible diagnosticar el proceso de la construcción social de la imagen de la arquitectura, explorar las restricciones y formatos de publicación de la plataforma, identificar los hábitos de reacción y difusión con relación a los rasgos visuales de la fotografía y ahondar en las posibilidades y los riesgos que introducen los sistemas de inteligencia artificial (IA). El método de investigación sigue un enfoque de asociación cognitiva a través del análisis de varios estudios de casos gráficos en Instagram. El diseño exploratorio para abordar el papel de la imagen para comunicar la arquitectura en las redes sociales visuales surge del concepto de fragmento y de la visión sesgada, división requerida por la naturaleza de las sugerencias de imágenes relacionadas como método de navegación en Instagram. Los hallazgos identifican oportunidades y estrategias de acción para complementar los contenidos que construyen la imagen colectiva de la arquitectura adaptados a la lógica del nuevo escenario

Enhancing magnetorheological effect using bimodal suspensions in the singlemultidomain limit

We demonstrate a new route to enhance the magnetorheological effect using bimodal suspensions in the single-multidomain limit. Experimental results are satisfactorily compared to 3D finite element method simulations. The physical reason behind this enhancement is the coating of the larger particles by the smaller ones due to the remnant magnetization of the latter.This work was supported by MAT 2016-78778-R and PCIN 2015-051 projects (FEDER FUNDS and MINECO, Spain).
