Balancing mechanics and metabolism: Elevational variation in the microanatomy of hummingbird flight muscle

The Anatomical Record, EarlyView.
Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

One Anatomy, Multiple Valve Choices: Interobserver Agreement in Selecting Transcatheter Pulmonary Valve

Catheterization and Cardiovascular Interventions, EarlyView.
Methodological framework among international observers to understand clinical decision‐making and interobserver agreement in TPVR planning. ABSTRACT Background Transcatheter pulmonary valve replacement (TPVR) requires selecting the optimal device type, size, and position. Variability in anatomical shape may affect procedural planning.

Nichtlineare Staubungsneigung binärer Schüttgutmischungen: Herausforderungen bei der Prognose Non‐linear dusting tendency of binary bulk material mixtures: Challenges in prognosis

Chemie Ingenieur Technik, EarlyView.
Aufgrund überlagerter oder konkurrierender Mechanismen sind relevante Wechselwirkungen bei der Staubung von Schüttgutmischungen komplex und nur unzureichend verstanden. Selbst für Mischungen aus umfassend charakterisierten Einzelkomponenten existieren keine belastbaren Modelle. In dieser Arbeit werden die Hürden bei der Prognose thematisiert.

Molekulare Solarthermiespeicher—zwei Fallstudien zur Optimierung Molecular solar thermal storage—two case studies on optimization

Chemie Ingenieur Technik, EarlyView.
Molekulare Solarthermiespeicher (MOST) überführen Licht in Wärmeenergie, die zu einem späteren Zeitpunkt genutzt werden kann. Die Optimierung solcher Systeme wird von vielen Parametern bestimmt, wie hier an zwei Beispielmolekülklassen, Azobenzole und Azaborinine, gezeigt.

Letting People in: Redefining Collaboration in Wildland–Urban Interface Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Intensifying wildfire regimes and expanding human settlements into wilderness areas have heightened concerns about the wildland–urban interface (WUI) due to the associated increase in fire risk. However, the WUI presents broader social‐ecological challenges that go beyond wildfire risk and remain understudied.

De los ‘condenados de la tierra’ a la tierra condenada

Andes, 2002
El tema de nuestro presente histórico es la justicia y el régimen político, en la medida en que ambos están siendo vulnerados en nuestras realidades socioculturales ante el implacable avance de la globalización neoliberal y su proyecto estadounimizador.
