Design of a Flexible Capture Mechanism Inspired by Sea Anemone for Non-cooperative Targets

open access: yesChinese Journal of Mechanical Engineering, 2021
Robotic grippers have been used in industry as end-effectors but are usually limited to operations in pre-defined workspace. However, few devices can capture irregularly shaped dynamic targets in space, underwater and other unstructured environments.

Higgs Mechanism for Gravitons

open access: yes, 2010
Just like the vector gauge bosons in the gauge theories, it is now known that gravitons acquire mass in the process of spontaneous symmetry breaking of diffeomorphisms through the condensation of scalar fields.

Instant preheating mechanism and UHECR [PDF]

open access: yes, 2004
Top-down models assume that the still unexplained Ultra High Energy Cosmic Rays (UHECR's) are the decay products of superheavy particles. Such particles may have been produced by one of the post-inflationary reheating mechanisms and may account for a ...

Mechanism Design with Aftermarkets: Cutoff Mechanisms [PDF]

open access: yesSSRN Electronic Journal, 2016
I study a mechanism design problem in which a designer allocates a single good to one of several agents, and the mechanism is followed by an aftermarket—a post‐mechanism game played between the agent who acquired the good and third‐party market participants.

Developmental Disorders in Children Recently Diagnosed With Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Neurocognitive deficits in adult survivors of childhood cancer are well established, but less is known about developmental disorders (DD) arising shortly after cancer diagnosis. Using 2016–2019 linked Ohio cancer registry and Medicaid data, we compared DD among 324 children with cancer and 606,913 cancer‐free controls.

Structural Design and Simulation of Passive Low Gravity Compensation for the Deployable Arm in the Device of Drilling and Collecting Lunar Soil

open access: yesMATEC Web of Conferences, 2015
As an important constituent part of the sampling device for lunar soil drilling, the deployable arm can help transfer the samples and avoid stretching. According to the ground experimental research requirements for deployable arm, this paper proposed a ...

Characterizing Parental Concerns About Lasting Impacts of Treatment in Children With B‐Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background B‐acute lymphoblastic leukemia (B‐ALL) is the most common pediatric cancer, and while most children in high‐resource settings are cured, therapy carries risks for long‐term toxicities. Understanding parents’ concerns about these late effects is essential to guide anticipatory support and inform evolving therapeutic approaches ...

Dynamic Modeling and Analysis of Rigid-Flexible Coupled Unfolding Mechanisms Under Transient Actuation

open access: yesApplied Sciences
Transient mechanisms are increasingly applied in fields such as high-speed aircraft, super high-speed trains, and underwater robots. However, in high-speed motion, large inertial forces are inevitably generated, which can easily lead to elastic ...

Mechanisms with Referrals: VCG Mechanisms and Multilevel Mechanisms [PDF]

open access: yesSSRN Electronic Journal, 2016
We study mechanisms for environments in which only some of the agents are directly connected to a mechanism designer and the other agents can participate in a mechanism only through the connected agents' referrals. Agents' network connections are private information, which can be strategically concealed by avoiding making referrals; while the mechanism
