Frailty Predicts Incident Osteoporotic Fractures in Veterans with Rheumatoid Arthritis
Arthritis Care &Research, Accepted Article.Background/Objective Rheumatoid arthritis (RA) is associated with an increased risk of frailty and osteoporosis, but the relationship between frailty and incident osteoporotic fractures in RA is underexplored. Methods Data were from the Veterans Affairs Rheumatoid Arthritis (VARA) Registry.

INFLUENCE OF INCLINATION ANGLE OF THE BOREHOLE AXIS ON THEPOSSIBLE MANIFESTATIONS OF RESERVOIR WATER
Известия высших учебных заведений: Нефть и газ, 2018 Secondary opening of productive oil and gas reservoirs by using cumulative and bullet perfo-ration methods in directional wells with high values of inclination angles (40-60º) requires a solution of technological problems caused by the justification of ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

L’écriture autobiographique ou l’horizon à reculons
Études Britanniques Contemporaines, 2011 We would like to explore the notion of horizon in autobiographical writing. It is a common thought that the autobiographer never looks further than his own belly-button. Still, taking that the writer becomes his own territory when he writes about himself,

The Myth of Long-Horizon Predictability [PDF]
The prevailing view in finance is that the evidence for long-horizon stock return predictability is significantly stronger than that for short horizons. We show that for persistent regressors, a characteristic of most of the predictive variables used in ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

A Fat Man on a Beach: Conflicting Horizons in B.S. Johnson’s Work
Études Britanniques Contemporaines, 2011 This essay proposes to analyse the co-existence in B.S. Johnson’s work of two apparently very different horizons: on the one hand, the writer’s utopian quest for truth which he tries to convey as faithfully as possible in his texts and films, even while ...
