Dynamic Instability of Beams Under Tip Follower Forces Using Geometrically Exact, Fully Intrinsic Equations

Latin American Journal of Solids and Structures
In this study, the dynamic instability of beams under tip follower forces are considered. The beam is modeled by using the geometrically exact, fully intrinsic beam equations which is subjected to an inclined tip follower force.

Ultradeep sequencing of a human ultraconserved region reveals somatic and constitutional genomic instability.

PLoS Biology, 2010
Early detection of cancer-associated genomic instability is crucial, particularly in tumour types in which this instability represents the essential underlying mechanism of tumourigenesis.

How light can the Higgs be?

, 2003
It is widely believed that, for a given Top mass, the Higgs mass has a lower bound: if m_Higgs is too small, the Higgs vacuum is unstable due to Top dynamics.

Study of fluidelastic instability in the streamwise and transverse directions through tube array under two-phase flow conditions using pressure effects

Nuclear Engineering and Technology
The fluidelastic instability (FEI) in heat exchanger tubes has been of widespread concern due to its tendency to cause damage to the tubes. Generally, FEI in the transverse direction of the tube occurs earlier than in the streamwise direction, and the ...

Boosting Policy Learning in Reinforcement Learning via Adaptive Intrinsic Reward Regulation

IEEE Access
Reinforcement learning employs heuristic intrinsic rewards to facilitate effective learning and exploration of the environment by intelligent agents. Particularly in environments with sparse rewards, it’s challenging for agents to reach goals or ...

The Zakharov–Kuznetsov equation for weakly nonlinear dust-acoustic waves in a magnetized nonthermal plasma with opposite polarity dust [PDF]

AIP Advances
The propagation properties and instability of dust-acoustic solitary waves (DASWs) are investigated in a dusty plasma consisting of inertial dust species of both positive and negative charge, non-inertial ions following Maxwellian distribution, and non ...

Causality and intrinsic thermoacoustic instability modes

, 2014
Direct numerical simulation of a confined laminar premixed flame has been performed in an anechoic combustor, showing self-sustained intrinsic thermoacoustic oscillations. Theoretical predictions based on acoustic jump relations and the n − τ model for the flame are presented and causality concerns are discussed.
