Nonlocomotory Robotic Strategies for Dynamic Rotation Control in Terrestrial Robots: A Review

Advanced Robotics Research, EarlyView.
Terrestrial robots increasingly require rapid body rotation to maintain stability and agility in complex environments. This review shows nonlocomotory rotational control strategies that operate without ground contact, including reaction wheels, tails, bars, limbs, and thrusters.

On manimax theory in two Hilbert spaces

International Journal of Mathematics and Mathematical Sciences, 1996
In this paper, we investigated the minimax of the bifunction J:H1(Ω)xV2→RmxRn, such that J(v1,v2)=((12a(v1,v1)−L(v1)),v2) where a(.,.) is a finite symmetric bilinear bicontinuous, coercive form on H1(Ω) and L belongs to the dual of H1(Ω).

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.

Towards a unified scheme of cortical lamination for primary visual cortex of primates: insights from NeuN and VGLUT2 immunoreactivity

Frontiers in Neuroanatomy, 2014
Primary visual cortex (V1) is clearly distinguishable from other cortical areas by its distinctive pattern of neocortical lamination across mammalian species.

Gait Analysis of Pak Biawak: A Necrobot Lizard Built using the Skeleton of an Asian Water Monitor (Varanus Salvator)

Advanced Robotics Research, EarlyView.
Pak Biawak, a necrobot, embodies an unusual fusion of biology and robotics. Designed to repurpose natural structures after death, it challenges conventional boundaries between nature and engineering. Its movements are precise yet unsettling, raising questions about sustainability, ethics, and the untapped potential of biointegrated machines.

Saccade-related modulations of neuronal excitability support synchrony of visually elicited spikes [PDF]

, 2011
During natural vision, primates perform frequent saccadic eye movements, allowing only a narrow time window for processing the visual information at each location.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

Advanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Green practices in wastewater treatment: Upcycling avocado waste for enhanced water sanitation. Case study: WWTP in San Francisco Pichátaro, Michoacán

Results in Engineering
Potable water and sanitation are priorities since pollutants pose health risks in Mexican rural communities. In this study, the San Francisco Pichataro (Michoacán) WWTP effluent was subjected to a post-bioadsorption treatment. For this purpose, activated
