Lost in Translation? Risk‐Adjusting RMSE for Economic Forecast Performance

Journal of Forecasting, EarlyView.
ABSTRACT When used for parameter optimization and/or model selection, traditional mean squared error (MSE)–based measures of forecast accuracy often exhibit a weak or even negative correlation with the economic value of return forecasts measured by, for example, the Sharpe ratios of the resulting portfolios.

Preoperative Planning for Total Hip Arthroplasty for Neglected Developmental Dysplasia of the Hip

Orthopaedic Surgery, 2019
Developmental dysplasia of the hip (DDH) is accompanied by morphological alterations on both the acetabular and the femoral side. Total hip arthroplasty (THA) provides effective treatment in cases of neglected DDH but requires elaborate preoperative ...

Reducing Limping by Tibial Lengthening Along Nails in Adult Unilateral Developmental Dysplasia of the Hip with High Dislocation

Journal of the Formosan Medical Association, 2008
Background/Purpose: Treatment of adult neglected developmental dysplasia of the hip (DDH) with high dislocation is still not established. The main concern of young patients is leg-length discrepancy (LLD), which leads to limping gait and impaired body ...

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil

Greenhouse Gases: Science and Technology, EarlyView.
ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

Using body mapping to explore perceptions of resilience with 7–12‐year‐old Muslim children in East London: A qualitative study

JCPP Advances, EarlyView.
This study explored resilience in Black and South Asian Muslim children aged 7–12 in East London, an underrepresented group affected by deprivation and discrimination. Using body mapping, children depicted resilience as personal strength and described the importance of support systems.

Nonlinear Dynamics of a Passive Walker: Bifurcation and Stability Insights With Spring and Damper Mechanics

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study explores the nonlinear dynamics associated with a passive dynamic walker (PDW), focusing on the bifurcation and stability insights derived from spring and damper mechanics. PDWs, which rely on gravity for stable locomotion without active control, exhibit a rich spectrum of behaviors, from periodic to chaotic motion.

Desigualdade estrutural discreta de membros inferiores é suficiente para causar alteração cinética na marcha de corredores? Is structural and mild leg length discrepancy enough to cause a kinetic change in runners' gait?

Acta Ortopédica Brasileira, 2008
Desigualdade de membros inferiores (DMI) está presente em cerca de 70% da população geral, podendo ser do tipo estrutural onde existe diferença no comprimento de estruturas ósseas, ou funcional, como resultado de alterações mecânicas dos membros ...
