We show that kinetochore movements in the fission yeast Schizosaccharomyces pombe are regulated by kinesinpromoted microtubule catastrophe, force-induced rescue, and microtubule dynamic instability. A candidate screen showed that among the selected motors only kinesin-8 motors Klp5/Klp6 are required for kinetochore centering.

Dynamic instability may refer to any of several scientific phenomena. Aircraft dynamic modes, including aircraft dynamic instability; Atmospheric instability, in meteorology; Dynamic instability of microtubules, in biology; Firehose instability, in astrophysics; Flutter, in aeroelasticity, a branch of mechanics; Hydrodynamic instability, in fluid dynamics.

Abstract. Dynamic stability is defined and classified, and examples are given for the various classes of problems. Criteria are developed for practical stability and it is shown that in a practical elastic column tested in a conventional testing machine stress reversal.

Dynamic Stability of Structures by Parametric instability or resonance is more dangerous than ordinary resonance as it is characterized by exponential growth of the response amplitudes even in the presence of damping.

The emphasis in this book is on the applications and various analytical and numerical methods for solving engineering problems.5/5(1).

Dynamic instability of elastic systems can occur when the applied forces are non-conservative.

The state of equilibrium of an elastic system may also become unstable in a dynamic fashion. For example, an equilibrated structure under non-conservative forces may undergo oscillations with increasing amplitude. This is called flutter instability.

Mitosis begins with prophase, which is marked by an increase in microtubule instability, triggered by M-Cdk. In animal cells, an unusually dynamic microtubule array (an aster) forms around each of the duplicated centrosomes, which separate to initiate the formation of the two spindle poles.

Interactions between the asters and a balance between. Dynamic instability refers to the coexistence of assembly and disassembly at the ends of a microtubule. The microtubule can dynamically switch between growing and shrinking phases in this region. Tubulin dimers can bind two molecules of GTP, one of which can be hydrolyzed subsequent to assembly.

This book presents a systematic introduction to the theory of parametric stability of structures under both deterministic and stochastic loadings. A comprehensive range of theories are presented and various application problems are formulated and solved, often using more than one approach.

Investigation of an elastic system's dynamic stability frequently leads to the study of dynamic behavior. Tailbone Book, Chapter 6: Unstable Tailbone.

Dynamic instability or dynamic buckling as applied to structures is a term that has been used to describe many classes of problems and many physical phenomena.

It is not surprising, then, that the term finds several uses and interpretations among structural mechanicians. Problems of parametricBrand: Springer-Verlag New York.

The book introduces concepts of dynamic buckling in the simplest possible context for each phenomenon. The phenomena treated all fall under the definition of dynamic stability of structures under time-varying parametric loading.

The goal is met by treating simple bars under axial loads, rings under lateral pulse loads, and cylindrical shells underFile Size: 1MB. dynamic stability[dī¦namik stə′bilədē] (mechanics) The characteristic of a body, such as an aircraft, rocket, or ship, that causes it, when disturbed from an original state of steady motion in an upright position, to damp the oscillations set up by restoring moments and gradually return to its original state.

Also known as stability. Dynamic Instability Is an Intrinsic Property of Microtubules. So far in this discussion we have painted a simple picture of the dynamic behavior of microtubules; that is, above the C c, tubulin subunits polymerize into microtubules, while below the C c, microtubules depolymerize into tubulin r, this simple picture of the behavior of an individual microtubule is by: 6.

Dynamic Tape has been thoroughly tested and recommended by FICS. The International Federation of Sports Chiropractic / Fédération Internationale de Chiropratique du Sport (FICS) is comprised of national chiropractic sports councils worldwide and individual members and has affiliations with international organizations within the chiropractic profession and the world of sports.

During microtubule assembly, hydrolysis of tubulin-bound GTP destabilizes the internal structure of a microtubule leading to a transition to shortening.

This switching between a growing and shortening state of microtubule is referred as dynamic instability. Microtubule Associated Proteins. Patrick Foye, M.D.

Diagnosis and Treatment of Cervical Spine Clinical Instability Kenneth A. Olson, MSc, P7; OCS, FAAOMPT1 Dustin)ode6 PT2 BACKGROUND Spinal instability is a major cause of neck pain, but unfortunately the concept of spinal instability is often ambiguous and poorly defined.

For clarity, instability will be referred to as clinical instability. This type of low frequency instability is referred to in literature as parallel-channel, density wave, time delay or mass flow-void feedback instability. Dynamic instability (density wave oscillation DWO) occurs because of the phase mismatch between the primary perturbation (water flow) and the response to this perturbation (pressure drop).Cited by: 1.

In this paper, the eigenmode linear superposition (ELS) method based on the regularization is used to discuss the distributions of all eigenmodes and the role of their instability to the intensity and structure change in TC-like vortex.

Results show that the regularization approach can overcome the ill-posed problem occurring in solving mode weight coefficients as the ELS method are applied to Author: Shuang Liu, Wei Zhong, Yudi Liu, Jie Xiang.

The influence of rotary inertia, shear deformation, and damping on dynamic instability regions has been investigated. The obtained numerical results are compared with those of the existing method. Numerical results indicate that the modified algorithm is a reliable approach for the solutions of this kind of problem in this investigation.

Dynamic Macroeconomics is an attempt to revitalize the traditions of nonmarket clearing approaches to macroeconomics. Using sophisticated tools from dynamic analysis, the authors introduce a consistent, integrated framework for disequilibrium macroeconomic dynamics and explore its relationship to the competing—and currently dominant—equilibrium dynamics.

It is shown that the conditions necessary for avoiding chatter may be Author: Macleod, G. The new nonlinear control theory developed by the authors that facilitates simultaneous control of vibration amplitude in the time-domain and spectral response in the frequency-domain provides the foundation for the development of a controller architecture universally viable for the control of dynamic instability including bifurcation and chaos.

Dispersion of normalized lateral strengths required to avoid dynamic instability are found to increase as the negative postyield stiffness decreases and as the period of vibration increases. Simple equations that capture the effects of period and postyield stiffness to aid in the evaluation of existing structures are obtained through nonliner.

This book is likely to become a standard undergraduate mathematics text in non-linear differential equations.’ Edward Ott Source: Nature ‘The author writes clearly and carefully, weaving together general results with a steady supply of simple examples and excercises for the by: Carpal instability is defined as an injury where there is a loss of normal alignment of the carpal bones and/ or the radioulnar joint.

The loss creates a disturbance of the normal balance of the carpal- and radioulnar joints which results in changes to the range of motion. The dynamic response of the riser is the consequence of the balance of the centrifugal, Coriolis, inertial, flexural restoring and drag forces.

The aim of this study is the analysis of the inner-flow-induced dynamic instability of curved risers made from fibre-reinforced by: 1.Dynamic stabilization of Rayleigh-Taylor instability in an ablation front is studied by considering a modulation in the acceleration that consists of sequences of Dirac deltas.
