Research of Dynamic Characteristic of RV Reducer based on Bond Graph Theory

Jixie chuandong, 2020
In view of the dynamic characteristic analysis of RV reducer is difficult problems. A simulation model of RV reducer is established based on the theory of power bond graph， the mathematical formula for transmission ratio of RV reducer is deduced， and the

Sampled-Data $\mathcal {L}_{2}-\mathcal {L}_{\infty }$ Consensus Control of Nonlinear Multi-Agent Systems

IEEE Access, 2017
The problem of sampled-data L2 - L∞ consensus control for the multi-agent systems with nonlinear dynamics and external disturbances is investigated via dynamic output feedback (DOF) strategy.

Non-orientable Boundary Superstring Field theory with Tachyon field

, 2001
We use the BSFT method to study the unoriented open string field theory (type I). The partition function on the Mobius strip is calculated. We find that, at the one-loop level, the divergence coming from planar graph and unoriented graph cancel each ...

RKIP overexpression reduces lung adenocarcinoma aggressiveness and sensitizes cells to EGFR‐targeted therapies

Molecular Oncology, EarlyView.
RKIP, a metastasis suppressor protein, modulates key oncogenic pathways in lung adenocarcinoma. In silico analyses linked low RKIP expression to poor survival. Functional studies revealed RKIP overexpression reduces tumor aggressiveness and enhances sensitivity to EGFR‐targeted therapies, while its loss promotes resistance.

Graph-theory induced gravity and strongly-degenerate fermions in a self-consistent Einstein universe

, 2011
We study UV-finite theory of induced gravity. We use scalar fields, Dirac fields and vector fields as matter fields whose one-loop effects induce the gravitational action.

Perturbative Noncommutative Quantum Gravity [PDF]

, 2000
We study perturbative noncommutative quantum gravity by expanding the gravitational field about a fixed classical background. A calculation of the one loop gravitational self-energy graph reveals that only the non-planar graviton loops are damped by ...

Emerging role of ARHGAP29 in melanoma cell phenotype switching

Molecular Oncology, EarlyView.
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein

An exact mapping between loop-erased random walks and an interacting field theory with two fermions and one boson

SciPost Physics, 2020
We give a simplified proof for the equivalence of loop-erased random walks to a lattice model containing two complex fermions, and one complex boson. This equivalence works on an arbitrary directed graph.

Containment Tracking Control of Multiple Airships With Noise

IEEE Access, 2022
This paper studies the containment control of multiple airships with multiple leaders disturbed by second-order moment processes. Firstly, the stochastic airship system is introduced by modeling in the mixed coordinate system.
