Achieving Immanent Organizational Ethics: Managing Paradoxical Tensions in Packaging
Business Strategy and the Environment, EarlyView.ABSTRACT Firms face strategic tensions in packaging materials through their conflicting but complementary social, environmental and economic goals in achieving sustainability. Reducing and repurposing plastics, glass, paper and cardboard in agriculture, horticulture and aquaculture is proving a challenge.

Miniaturized Hyper-Redundant Manipulator Using Multi-Cable for Minimally Invasive Surgery
IEEE AccessMinimally invasive surgery (MIS) using robots minimizes patient injury but is challenging due to reduced bending force in smaller-diameter tools. Lowering the bending resistance of actuating cables is critical, particularly when tool diameters are small ...

Mitigating measurement error in misspecified small area models
Canadian Journal of Statistics, EarlyView.Abstract In the framework of Small area estimation, we consider an area‐level model where a subset of covariates is measured with error. The extent of the error is assumed to be constant throughout the areas, and it is expressed by a scalar parameter γ$$ \gamma $$, which multiplies the deterministic covariance matrix of the estimator of the true ...

Neural network based kinematic control of the hyper-redundant snake-like manipulator
, 2007 In a sinusoid like curve configuration, the snake-like manipulator (also called snake arm) has a wide range of potential applications for its redundancy to overcome conventional industrial robot's limitation when carrying out a complex task.

Visualizing Specific Tubulin Isotypes and Pathogenic Variants in Cellular Microtubule Arrays
Cytoskeleton, EarlyView.ABSTRACT Eukaryotic cells depend on dynamic microtubule arrays to execute a wide range of functions vital for life. These microtubule filaments are formed through the polymerization of α/β‐tubulin proteins, which can be generated from numerous tubulin genes, or isotypes.

Edge Fluid Turbulence Simulations of Stellarators With GRILLIX
Contributions to Plasma Physics, EarlyView.ABSTRACT The edge fluid turbulence code GRILLIX has recently been extended from axisymmetric tokamak geometries to support 3D stellarator configurations. Following successful proof‐of‐principle simulations published in Stegmeir et al., we present here a comprehensive simulation of the Wendelstein 7‐AS stellarator.
