REDUCTION OF MODELS IN THE PRESENCE OF NUISANCE PARAMETERS REDUCCIÓN DE MODELOS EN LA PRESENCIA DE PARÁMETROS DE PERTURBACIÓN

Revista Colombiana de Estadística, 2009
In many statistical inference problems, there is interest in estimation of only some elements of the parameter vector that defines the adopted model.

Solving Nuisance Cyanobacteria Eutrophication Through Biotechnology

Applied Sciences, 2019
Management of nutrient inputs and usage of nuisance biomass as feedstock for bioenergy may be the solution of coastal lagoons eutrophication. We studied the species composition, photosynthetic pigments (Chl-a and Chl-c) and performance (OJIP-kinetics and

Ultrafast fMRI Detects Age‐Related Changes in Harmonics of Cardiac Pulsations in the Brain at 7 T

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Aging impacts pulsatility of blood vessels in the brain, reflecting vascular health. Resolving characteristics of cardiac pulsatility requires faster acquisitions than traditional fMRI. An ultrafast fMRI method was developed and applied to sample several harmonics of cardiac pulsations at 7 T.

Methods for Uncertainty Quantification in Dictionary Matching to Advance Reliability of Quantitative MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Aims Purpose: Dictionary matching is a standard tool in quantitative MRI (qMRI), but typically lacks uncertainty quantification (UQ). This is critical when advanced reconstructions (e.g., compressed sensing, deep learning) introduce complex‐valued, spatially varying, and temporally correlated noise that violates standard assumptions of ...

Low complexity iterative detection in the presence of nuisance parameters

, 2010
This work addresses the bit-wise optimal data detection problem when unknown nuisance parameters influence the observation at the receiver. For an arbitrary communications system, the optimal maximum a-posteriori detection problem is first defined as a ...

Circulant Matrix‐Based Box–Behnken Designs With Economic Run Sizes

Quality and Reliability Engineering International, EarlyView.
ABSTRACT We introduce Circulant Matrix‐Based Box–Behnken Designs (CBBDs), a new class of three‐level, second‐order response surface designs constructed using circulant matrix structures. These designs satisfy an enhanced orthogonal minimally aliased (OMA∗${\rm OMA}^*$) property: they retain the classical OMA property—where main effects are orthogonal ...

Effects of Engineered Dam Releases on Benthic Assemblages During Drought and Comparison With Unregulated Reaches

River Research and Applications, EarlyView.
ABSTRACT River regulation following damming is often associated with deleterious downstream effects, in large part due to reduced total discharge and disruption of seasonal flooding. These effects would be expected to be exacerbated by drought, particularly extended drought.
