Robotic Needle Steering for Percutaneous Interventions: Sensing, Modeling, and Control
Advanced Intelligent Systems, EarlyView.This review examines recent advances in robotic needle steering for percutaneous interventions, highlighting closed‐loop sensing, physics‐informed tissue‐needle interaction modeling, and real‐time trajectory planning and control. It synthesizes innovations in deep learning, fiber‐optic feedback, and adaptive control strategies, and outlines emerging ...

Entropy, 2019 The observable representation (OR) is an embedding of the space on which a stochastic dynamics is taking place into a low dimensional Euclidean space. The most significant feature of the OR is that it respects the dynamics.

Temperature effects on Florida applesnail activity: implications for snail kite foraging success and distribution [PDF]
, 2002 The endangered Florida snail kite (Rostrhamlls sociaiJilis) feeds exclusively on applesnails (Pomacea pailiclosa), yet we lack direct observations that link applesnail behavior to snail kite foraging success.

Grass functional traits reflect the long history of fire and grazers in the savannas of Texas
American Journal of Botany, EarlyView.Abstract Premise Understanding relationships among grass traits, fire, and herbivores may help improve conservation strategies for savannas that are threatened by novel disturbance regimes. Emerging theory, developed in Africa, emphasizes that functional traits of savanna grasses reflect the distinct ways that fire and grazers consume biomass ...

Insulin Modifies Honeybee Worker Behavior
Insects, 2012 The insulin signaling pathway has been hypothesized to play a key role in regulation of worker social insect behavior. We tested whether insulin treatment has direct effects on worker honeybee behavior in two contexts, sucrose response thresholds in ...

Individual Variation Does Not Regulate Foraging Response to Humidity in Harvester Ant Colonies
Frontiers in Ecology and Evolution, 2022 Differences among groups in collective behavior may arise from responses that all group members share, or instead from differences in the distribution of individuals of particular types.

, 2016 This chapter focuses on conserving forage as hay or silage. Conserving forage is an essential component of ruminant livestock production systems in most temperate climates, but in subtropical and tropical regions the use of hay and silage is not as widespread.

American Journal of Botany, EarlyView.Abstract Premise Climate change poses challenges to grasslands, including those of the North American Great Plains Region, where shifts in species distributions and fire dynamics are expected. Our present analysis focuses on remaining grasslands within this largely developed and agricultural region. The differential responses of C4 and C3 grass species

Quitting time: When do honey bee foragers decide to stop foraging on natural resources?
Frontiers in Ecology and Evolution, 2015 Honey bee foragers may use both personal and social information when making decisions about when to visit resources. In particular, foragers may stop foraging at resources when their own experience indicates declining resource quality, or when social ...

Influence of spatial and temporal dynamics of agricultural practices on the lesser kestrel [PDF]
, 2011 1. European agriculture is facing dramatic changes that are likely to have marked impacts on farmland biodiversity. There is an urgent need to develop land management strategies compatible with the conservation of biodiversity.2.
