Global Convergence of a Curvilinear Search for Non-Convex Optimization
(2022-08-26)For a non-convex function f : R^n → R with gradient g and Hessian H, define a step vector p(μ,x) as a function of scalar parameter μ and position vector x by the equation (H(x) + μI)p(μ, x) = −g(x). Under mild conditions ... -
Global convergence using de-linked Goldstein or Wolfe linesearch conditions
(2009)Goldstein or Wolfe conditions can be imposed on a linesearch to ensure convergence of an iterative nonlinear optimization algorithm to a stationary point. However it is actually not necessary to find a single step which ... -
The global financial crisis and integration in European retail banking
(2014-03-31)The aim of this paper is twofold. Firstly, to investigate the integration process within the European Union retail banking sector by analysing deposit and lending rates to the household sector during the period 2003-2011. ... -
Global financial uncertainty shocks and external monetary vulnerability: the role of dominance, exposure, and history
(2023-10-30)The paper investigates the role of country-specific factors in external monetary vulnerability to global uncertainty shocks. We identify three structural determinants that may shape cross-country heterogeneity in the ... -
The global gas and dust budget of the Large Magellanic Cloud: AGB stars and supernovae and the impact on the ISM evolution
(2009)We report on an analysis of the gas and dust budget in the interstellar medium (ISM) of the Large Magellanic Cloud (LMC). Recent observations from the Spitzer Space Telescope enable us to study the mid-infrared dust excess ... -

Global Information Warfare : The New Digital Battlefield, Second Edition
(Auerbach Publications, 2015-09-25)Since the turn of the century much has happened in politics, governments, spying, technology, global business, mobile communications, and global competition on national and corporate levels. These sweeping changes have ... -
Global Liquidity, the Private Sector and Debt Sustainability in Sub-Saharan Africa
(2019-05-09)This article analyses the effect of changes in international financial markets on the debt dynamics in sub-Saharan Africa in recent years. A key development is the rise of the private sector as both a lender and a borrower ... -
Global Mechanisms and Higher Education
(2010)In a complex, fast changing global environment the very nature and definition of education is under contestation. The key issues coming to the fore appear to be who will be allowed to learn what, and under which circumstances? ... -
Global morphology and physical relations between the stars, gas and dust in the disc and arms of M100
(1996)We study star formation processes in the disc of the weakly barred grand design spiral galaxy M100 (NGC 4321) from a variety of images tracing recent massive star formation, old and young stars, dust, and neutral hydrogen. ... -
A global observational analysis to understand changes in air quality during exceptionally low anthropogenic emission
(2021-08-20)This global study, which has been coordinated by the World Meteorological Organization Global Atmospheric Watch (WMO/GAW) programme, aims to understand the behaviour of key air pollutant species during the COVID-19 pandemic ... -

A global optimization approach to solve multi-aircraft routing problems
(Engineering Science Reference (IGI-Global), 2009)This paper describes the formulation and solution of a multi-aircraft routing problem which is posed as a global optimization calculation. The paper extends previous work (involving a single aircraft using two dimensions) ... -
A global optimization problem in portfolio selection
(2009)This paper deals with the issue of buy-in thresholds in portfolio optimization using the Markowitz approach. Optimal values of invested fractions calculated using, for instance, the classical minimum-risk problem can be ... -
Global patterns in genomic diversity underpinning the evolution of insecticide resistance in the aphid crop pest Myzus persicae
(2021-07-07)Abstract: The aphid Myzus persicae is a destructive agricultural pest that displays an exceptional ability to develop resistance to both natural and synthetic insecticides. To investigate the evolution of resistance in ... -
Global Restructuring of Value Chains and Class Issues
(2009)This paper looks at the impacts of the restructuration of global value chains are skills, occupational identities, class position and class consciousness. The codification of tacit knowledge and standardisation of work ... -
Global statistical model calculations and the role of isospin
(IOP Publishing Ltd., 1998)An improved code for the calculation of astrophysical reaction rates in the statistical model is presented. It includes the possibility to study isospin effects. Such effects heavily affect rates involving self-conjugate ... -
The global status of insect resistance to neonicotinoid insecticides
(2015-06-30)The first neonicotinoid insecticide, imidacloprid, was launched in 1991. Today this class of insecticides comprises at least seven major compounds with a market share of more than 25% of total global insecticide sales. ...
