Bifurcation Curves in Discontinuous Maps [PDF]

Several discrete-time dynamic models are ultimately expressed in the form of iterated piecewise linear functions, in one or two-dimensional spaces. In this paper we study a one-dimensional map made up of three linear pieces which are separated by two ...

Spatial Mismatch Between Angiographic Obstruction and Plaque Destabilization in Acute Coronary Syndromes: A Conceptual Narrative Review

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT The identification of the “culprit lesion” in acute coronary syndromes (ACS) traditionally relies on coronary angiography, assuming that the most severe stenosis, abrupt occlusion, or largest filling defect marks the site of plaque destabilization.

A Meta‐Analytic Review of Board Characteristics and Carbon Emission Disclosure: The Moderating Effect of Contextual Factors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...

Study on Triopoly Dynamic Game Model Based on Different Demand Forecast Methods in the Market

Complexity, 2017
The impact of inaccurate demand beliefs on dynamics of a Triopoly game is studied. We suppose that all the players make their own estimations on possible demand with errors. A dynamic Triopoly game with such demand belief is set up.

Exploring the Role of Competitiveness in Sustainability Standards: Insights From an Animal Welfare Scheme Adopted by Supermarkets

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.

Bifurcation and synchronization analysis in a stall-flutter aeroelastic system under varying preset angles and frequency ratios

Scientific Reports
This study experimentally investigates the bifurcation characteristics and synchronization mechanisms in an aeroelastic system exhibiting nonlinear stall flutter behaviour, with particular emphasis on the influence of varying preset angles of incidence ...

Modeling complex flow dynamics of fluvial floods exacerbated by sea level rise in the Ganges–Brahmaputra–Meghna Delta

Environmental Research Letters, 2015
Global warming is likely to exacerbate future fluvial floods in the world’s mega-delta regions due to both changing climate and rising sea levels. However, the effects of sea level rise (SLR) on fluvial floods in such regions have not been taken into ...

Complementing maps, continuation and global bifurcation [PDF]

, 1983
We state, and indicate some of the consequences of, a theorem whose sole assumption is the nonvanishing of the Leray- Schauder degree of a compact vector field, and whose conclusions yield multidimensional existence, continuation and bifurcation ...

Persistent Motion and Chaos in Attitude Control with Switching Actuator [PDF]

, 2005
In systems with switching actuators persistent motions of different nature may occur, such as limit cycles, quasi-periodic and chaotic motions. In this contribution the nature of persistent motions in an attitude control system with switching actuators ...

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.
