Two-Finger Grasping Virtual Environment with Realistic Stick-Slip Vibration

We propose a two-finger grasping virtual environment that generates realistic vibrations and frictions when the virtual fingers make contact with and slide over virtual objects.

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Making Mining Licit: Gold, Commodification, and the Everyday Performance of Law in Colombia

American Anthropologist, EarlyView.
ABSTRACT Ethnographies of resource‐making have shown that the extraction of resource value from objects is premised on obviating the emplaced lifeworlds that surrounded objects before they traveled to consumer markets. Much of this literature looks at such supply‐chain disentanglement from the viewpoint of corporate and formal regulatory practices ...

An Investigation of Surface Vibration, Airbourne Sound and Acoustic Emission Characteristics of a Journal Bearing for Early Fault Detection and Diagnosis

High power machinery such as steam turbines, large pumps and motors often use journal bearings as rotor supports. This type of bearing is simple, low cost and with high load carrying capacity.

Mixed Super‐Circles

Computer Graphics Forum, EarlyView.
Abstract We introduce mixed super‐circles, a position‐curvature formulation of the original dynamic 2D super‐helix model. Compared to the latter, purely curvature‐based model – the so‐called chained formulation –, the mixed formulation that we propose here drastically reduces the algorithmic complexity of the solving scheme – from quadratic to quasi ...

Friction and vibration generated during sliding over bare skin correlate with perceived smoothness and moistness

International Journal of Cosmetic Science, EarlyView.
A tactile sensor with a probe replicating a fingerprint quantified skin texture by measuring vibration and friction. Regression analysis linked smoothness and moistness perceptions with high‐frequency vibration amplitude and friction. These findings support the objective assessment of skin texture, enhancing product evaluation consistency and bridging ...
