Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

Risk-Sensitive Dividend Problems

, 2014
We consider a discrete-time version of the popular optimal dividend pay-out problem in risk theory. The novel aspect of our approach is that we allow for a risk averse insurer, i.e., instead of maximising the expected discounted dividends until ruin we ...

Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains

Advanced Robotics Research, EarlyView.
How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

Techno-economic analysis of a microgrid design for a commercial health facility in Ghana- Case study of Zipline Sefwi-Wiawso

Scientific African, 2023
Most commercial entities depend on the availability, and reliability of electricity supply for their business ventures. Poor energy security, unreliability, and high cost of electricity characterize the utility grid of Ghana, forcing most of these ...

Promoting Treg Polarization‐Mediated Anti‐Scar and Appendage Regeneration in Wound Healing

Advanced Science, EarlyView.
This study develops a PLGA@LA‐BMP4‐PG bilayer scaffold to address scar formation and appendage loss in skin repair. The piezoelectric PLA layer enhances cell migration via electric fields, while GelMA delivers LA promoting Tregs polarization and BMP4 inhibiting FBs differentiation.

Price Attractiveness and Price Complexity: Why People Prefer Level-Payment Loans

Frontiers in Psychology, 2021
The improving sequence effect suggests that in choices between a rising earning and any other sequences, participants prefer the rising earning. Recent studies show that the improving sequence effect also exists in a loan context.

Farnesyltransferase Deficiency in Cardiomyocytes Initiates Senescence and Contributes to Cardiac Fibrosis

Advanced Science, EarlyView.
Lipid overload suppresses SREBF2‐mediated FNTB expression, leading to defective Lamin A maturation and nuclear envelope instability. This nuclear catastrophe triggers a pro‐fibrotic senescence program in cardiomyocytes. Notably, restoring nuclear integrity via AAV9‐based gene therapy effectively attenuates cardiac remodeling, identifying the ...

Designing Cost‐Effective Carbon Payments to Induce Cellulosic Feedstock Production for Sustainable Aviation Fuel

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Perennial bioenergy crops, such as miscanthus and switchgrass, and crop residues have the potential to scale up sustainable aviation fuel (SAF) production and mitigate carbon emissions. However, high establishment costs, delayed returns, and risk–return profiles that diverge from those of conventional crops can hinder incentives to adopt ...

Peanuts effect in intertemporal decision-making processes.

INFAD, 2017
The intertemporal choice refers to the individual decision-making process when analyzing the preferences between two rewards with different due dates. That is to say, it aims to analyze the preferences between two rewards (x1,t1) and (x2,t2) , where x1x2
