Calibration for Computer Models with Time-Varying Parameter
MathematicsTraditional calibration methods often assume constant parameters that remain unchanged across input conditions, which can limit predictive accuracy when parameters actually vary.

Local asymptotic normality for multivariate linear processes
Stochastic Processes and their Applications, 1994 Let \(\{x_ t\}\) be i.i.d. \(d\)-dimensional random vectors and \(\{\gamma_ j\}\) \(d \times d\) nonrandom matrices. The author considers a linear process \(y_ t=\sum^ \infty_{j=0} \gamma_ j x_{t-j}\). Local asymptotic normality (LAN) is established for the likelihood ratios for the distribution of \((x_ j:j \leq 0\), \(y_ 1,\dots,y_ n)\).

Advanced Electronic Materials, EarlyView.This work presents a study of how 4D‐STEM centre of mass measurements and STEM‐EBIC can be used to map the positions, directions, and strengths of electric fields in semiconductor devices. The contrast mechanisms of both techniques are tested and compared with simulations to build a robust analysis of an in situ device in the electron microscope ...

Gamma Kernel Estimators for Density and Hazard Rate of Right-Censored Data
Journal of Probability and Statistics, 2011 The nonparametric estimation for the density and hazard rate functions for right-censored data using the kernel smoothing techniques is considered. The “classical” fixed symmetric kernel type estimator of these functions performs well in the interior ...

Testing uniformity on high-dimensional spheres against monotone rotationally symmetric alternatives
, 2016 We consider the problem of testing uniformity on high-dimensional unit spheres. We are primarily interested in non-null issues. We show that rotationally symmetric alternatives lead to two Local Asymptotic Normality (LAN) structures. The first one is for

Agribusiness, EarlyView.ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

, 2005 Let I_1,...,I_n be independent but not necessarily identically distributed Bernoulli random variables, and let X_n=\sum_{j=1}^nI_j. For \nu in a bounded region, a local central limit theorem expansion of P(X_n=EX_n+\nu) is developed to any given degree ...

Consumer Preferences for Craft Beer: The Interplay of Localness and Advertising Language
Agribusiness, EarlyView.ABSTRACT This study explores the influence of the language of the label, origin of production, and origin of brewing ingredients on Croatian consumers' preferences and willingness to pay for organic craft beer. Employing an online survey and a choice experiment among 223 Croatian alcohol consumers, we find that while there's a willingness to pay a ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The hybrid nanofluid integrated with micropolar fluid shows growing interest due to the enhanced thermal performance in microscale devices. These improved properties are due to their greater thermal conductivity and rotational effects. The proposed study assesses the significance of velocity slip on the flow characteristic of micropolar ...
