A Bimodal Hydrostatic Actuator for Robotic Legs with Compliant Fast Motion and High Lifting Force [PDF]
arXiv, 2022 Robotic legs have bimodal operations: swing phases when the leg needs to move quickly in the air (high-speed, low-force) and stance phases when the leg bears the weight of the system (low-speed, high-force). Sizing a traditional single-ratio actuation system for such extremum operations leads to oversized heavy electric motor and poor energy efficiency,

Extension of Dancer’s Legs: Increasing Angles Show Motion
Frontiers in Psychology, 2022 Usain Bolt’s Lightning Bolt pose, one arm highly extended to one side, suggests action. Likewise, static pictures of animals, legs extended, show animation. We tested a new cue for motion perception—extension—and in particular extension of dancer’s legs.

SWheg: A Wheel-Leg Transformable Robot With Minimalist Actuator Realization [PDF]
arXiv, 2022 This article presents the design, implementation, and performance evaluation of SWheg, a novel modular wheel-leg transformable robot family with minimalist actuator realization. SWheg takes advantage of both wheeled and legged locomotion by seamlessly integrating them on a single platform. In contrast to other designs that use multiple actuators, SWheg

The Third Leg of Two-legged Lexicography
HERMES - Journal of Language and Communication in Business, 2017 This article argues that the essence of lexicography is its capacity to satisfy the potential users’ punctual information needs in contrast to their global information needs. Simultaneously it shows that lexicographic theory, which so far has studied only two basic types of social situations where information needs may occur, the communicative and ...

Inhibitor of DNA binding‐1 is a key regulator of cancer cell vasculogenic mimicry
Molecular Oncology, EarlyView.Elevated expression of transcriptional regulator inhibitor of DNA binding 1 (ID1) promoted cancer cell‐mediated vasculogenic mimicry (VM) through regulation of pro‐angiogenic and pro‐cancerous genes (e.g. VE‐cadherin (CDH5), TIE2, MMP9, DKK1). Higher ID1 expression also increased metastases to the lung and the liver.

A solvable walking model for a two-legged robot [PDF]
arXiv, 2022 We present a solvable biped walking model based on an inverted pendulum with two massless articulated legs capable of walking on uneven floors and inclined planes. The stride of the two-legged robot results from the pendular motion of a standing leg and the articulated motion of a trailing leg.

Bone‐wise rigid registration of femur, tibia, and fibula for the tracking of temporal changes
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Multiple myeloma (MM) induces temporal alterations in bone structure, such as osteolytic bone lesions, which are challenging to identify through manual image interpretation. The large variation in radiologists' assessments, even at expert centers, further complicates diagnosis.
