THE VAR AT RISK [PDF]

open access: yesInternational Journal of Theoretical and Applied Finance, 2010
I show that the structure of the firm is not neutral with respect to regulatory capital budgeted under rules which are based on the Value-at-Risk. Indeed, when a holding company has the liberty to divide its risk into as many subsidiaries as needed, and when the subsidiaries are subject to capital requirements according to the Value-at-Risk budgeting ...

Gauge transformations of Spin-Orbit interactions in graphene

open access: yes, 2015
Inclusion of spin-dependent interactions in graphene in the vicinity of the Dirac points can be posed in terms of non-Abelian gauge potentials. Such gauge potentials being surrogates of physical electric fields and material parameters, only enjoy a ...

Carbonatation and Decarbonatation Kinetics in the La2O3-La2O2CO3 System under CO2 Gas Flows

open access: yesAdvances in Materials Science and Engineering, 2010
The carbonatation of La2O3 oxide and the decarbonatation of lanthanum carbonate phase La2O2CO3 are investigated using thermal and thermogravimetry analyses under CO2 gas flow.

VAR(1) Based Models Do Not Always Outpredict AR(1) Models in Typical Psychological Applications

open access: yesPsychological methods, 2018
In psychology, modeling multivariate dynamical processes within a person is gaining ground. A popular model is the lag-one vector autoregressive or VAR(1) model and its variants, in which each variable is regressed on all variables (including itself) at ...

Bionics Solution to Learn the Arm Reaching with Collision Avoidance

open access: yesApplied Bionics and Biomechanics, 2005
This article presents a learning model that simulates the control of an anthropomorphic arm kinematics motion. The objective is to reach and grasp a static prototypic object placed behind different kinds of obstacle in size and position.

Financial Shocks, Uncertainty Shocks, and Corporate Liquidity

open access: yesJournal of Applied Econometrics, Volume 40, Issue 7, Page 814-828, November/December 2025.
ABSTRACT I estimate a structural VAR identified using sign restrictions to separately identify financial, macro uncertainty, and financial uncertainty shocks. The novelty of the estimation procedure relies on the qualitatively different response of corporate liquidity: Financial shocks lead firms to draw down their liquidity as they lose access to ...

Life in deep subsurface

open access: yesE3S Web of Conferences, 2016
Life extends far deeper into the Earth's subsurface than presumed possible 30 years ago. In the past, it was assumed that life is a surface phenomenon, and that even “hardy prokaryotic types” are not capable of living deeper than tens of meters below the

The Economic Value of Forecasts in Reducing Extreme Total Losses

open access: yesMeteorological Applications, Volume 32, Issue 6, November/December 2025.
This study has derived expressions for the variance of losses when making forecasts and finds that it plays an important role in determining the extreme losses that can be incurred when forecasting rare events. ABSTRACT A major aim of weather and other types of environmental forecasting is to provide early warning of extreme hazards that can then be ...

Assessment of asymmetry and trajectory during repeated twenty-meter sprints in court sports wheelchair athletes

open access: yesFrontiers in Sports and Active Living
IntroductionManual wheelchair (MWC) propulsion relies on upper limb power, coordination, and endurance. Propulsion asymmetry can reduce efficiency, yet the impact of fatigability on upper limb asymmetry remains underexplored.
