Sexual ornaments do not impair predator evasion in stalk-eyed flies

Frontiers in Ethology
Sexually selected ornaments can impose biomechanical constraints on locomotion and potentially affect predator avoidance. In stalk-eyed flies, males possess elongated eyestalks that increase head width and may elevate rotational inertia during flight ...

Avoidance maneuevers selected while viewing cockpit traffic displays [PDF]

, 1982
Ten airline pilots rates the collision danger of air traffic presented on cockpit displays of traffic information while they monitored simulated departures from Denver. They selected avoidance maneuvers when necessary for separation.

SemanticST: A Scalable Multi‐Contextual Graph Learning Framework for Uncovering Spatial Niches and Robust Multi‐Sample Integration in Spatial Transcriptomics

Advanced Science, EarlyView.
Technical limitations often let dominant signals overshadow rare cell types and fine‐grained heterogeneity in spatial transcriptomics. SemanticST, a graph neural network using multi‐semantic graph fusion and a novel min‐cut loss, recovers these subtle patterns.

A mechanistic understanding of collective escape in starling flocks

Communications Biology
Large flocks of European starlings change shape, size, and internal structure continuously and rapidly when hunted by aerial predators. How their diverse patterns of collective escape emerge is still unknown.

Computationally Efficient Observer-Based Robust MPC for High-Speed Vehicle Centralized Trajectory Tracking With H_∞ Disturbance Attenuation

IEEE Open Journal of Intelligent Transportation Systems
This paper proposes a novel centralized trajectory tracking LPV controller for automated vehicles based on Observer-Based Robust Model Predictive Control (OB-RMPC), combining longitudinal and lateral control of the vehicle through a coupled dynamics ...

Blood Cell‐Camouflaged Liquid Metal Nanoconjugates Orchestrate Treg Depletion and STING‐Amplified Photothermal Immunity for Metastatic Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Whole‐blood biomimetic engineering transforms liquid metal nanoparticles into a tripartite immunotherapeutic platform that orchestrates regulatory T‐cell depletion, photothermal‐induced immunogenic cell death, and activation of the stimulator of interferon genes pathway.

Trajectory Optimization for Aircraft Evasive Maneuvering

, 2017
The aim of this work has been to identify hidden parameter value patterns during evasive maneuvering for a typical jet fighter. The work has created a performance model for a fighter aircraft and this model has then been combined with a missile model to simulate an enemy attack.

Study of evasive maneuvers considering orbital perturbations

, 2015
We studied the problem of the viability of space missions in debris environment space. Generally, a space vehicle in collision course with a space debris is destroyed or damaged and has impaired their mission.
