Estimation of soybean crop water deficit sensitivity index [PDF]

open access: yesScientia Agricola
Brazil is the world’s largest soybean exporter. Over half of the cultivated area is in the Brazilian Savanna (Cerrado) region, where soybean is typically grown under rainfed conditions. However, soybeans have been cultivated in irrigated systems, further

Spectral sensitivity estimation of trichromatic camera based on orthogonal test and window filtering.

open access: yesOptics Express, 2020
The three-channel spectral sensitivity of a trichromatic camera represents the characteristics of system color space. It is a mapping bridge from the spectral information of a scene to the response value of a camera.

Mitigation of biases in estimating hazard ratios under non-sensitive and non-specific observation of outcomes–applications to influenza vaccine effectiveness

open access: yesEmerging Themes in Epidemiology, 2021
Background Non-sensitive and non-specific observation of outcomes in time-to-event data affects event counts as well as the risk sets, thus, biasing the estimation of hazard ratios.

Proper Estimation of Sensitivity and Specificity [PDF]

open access: yesClinical and Vaccine Immunology, 2006
I write to express concern about the diagnostic accuracy statements of Eda et. al. concerning a new Johne's disease enzyme-linked immunosorbent assay (ELISA) (2). The diagnostic sensitivity of this new ELISA for bovine paratuberculosis, reported to be 100%, was based on only 64 (according to the Materials and Methods) or 51 (according to the Results)

Input-Output Selection for LSTM-Based Reduced-Order State Estimator Design

open access: yesMathematics, 2023
In this work, we propose a sensitivity-based approach to construct reduced-order state estimators based on recurrent neural networks (RNN). It is assumed that a mechanistic model is available but is too computationally complex for estimator design and ...

Improved Sensitivity Estimate for the H 2 Estimation Problem [PDF]

open access: yes, 2006
The paper deals with the local sensitivity analysis of the discrete-time infinite-horizon H2 estimation problem. An improved, nonlinear sensitivity estimate is derived which is less conservative than the existing, condition number based sensitivity estimates.

Temporal resolution of vegetation indices and solar-induced chlorophyll fluorescence data affects the accuracy of vegetation phenology estimation: A study using in-situ measurements

open access: yesEcological Indicators, 2022
Vegetation phenology plays a critical role in inter-annual changes of the terrestrial carbon cycle. Land surface phenology (LSP) has been widely used to monitor vegetation phenology from remotely-sensed data (RSD) across multiple spatial scales. However,

Sensitivity of the Gme Estimates to Support Bounds [PDF]

open access: yes, 2001
The claim has been made that the Generalized Maximum Entropy (GME) estimator of Golan, Judge and Miller is not sensitive to variations in the support bounds of either the parameters or the error terms. In this paper, we scrutinized this claim by means of Monte Carlo experiments and found that the parameter estimates are impacted in a substantial way by

NCFET-Based 6-T SRAM: Yield Estimation Based on Variation-Aware Sensitivity

open access: yesIEEE Journal of the Electron Devices Society, 2020
The key feature of NCFET (negative capacitance field effect transistor) is its sub-threshold slope (SS) <; 60 mV/decade at 300 K. In this work, the n-type NCFET (i.e., pull-down (PD) and passgate (PG) transistor in six-transistor (6T) SRAM bit-cell ...

Estimation of insulin sensitivity from continuous glucose monitoring and insulin pump data in type 1 diabetes [PDF]

open access: yes, 2022
Diabetes mellitus is a disease characterized by chronic hyperglycemia either due to a lack of secretion of the hormone insulin (Type 1 Diabetes Mellitus, T1DM) or due to impaired action of this hormone (Type 2 Diabetes Mellitus, T2DM).
