Influence functionals and the accelerating detector [PDF]

open access: yesPhysical Review D, 1993
The influence functional is derived for a massive scalar field in the ground state, coupled to a uniformly accelerating DeWitt monopole detector in $D+1$ dimensional Minkowski space. This confirms the local nature of the Unruh effect, and provides an exact solution to the problem of the accelerating detector without invoking a non-standard quantization.

Restricted Distance-Type Gaussian Estimators Based on Density Power Divergence and Their Applications in Hypothesis Testing

open access: yesMathematics, 2023
In this paper, we introduce the restricted minimum density power divergence Gaussian estimator (MDPDGE) and study its main asymptotic properties. In addition, we examine it robustness through its influence function analysis.

Robust Inference after Random Projections via Hellinger Distance for Location-Scale Family

open access: yesEntropy, 2019
Big data and streaming data are encountered in a variety of contemporary applications in business and industry. In such cases, it is common to use random projections to reduce the dimension of the data yielding compressed data. These data however possess

INFLUENCE OF OLANZAPINE ON MEMORY FUNCTIONS

open access: yesPsychiatria Danubina, 2009
Even though memory dysfunction is not considered to be a diagnostic criterion for schizophrenia, results of a neuropsychological research indicate significant damage in mnestic functioning, especially in verbal memory (Saykin et al. 1991). This type of a disorder is recorded in patients with a first episode of schizophrenia, as well as in chronic ...

Robust Bootstrap

open access: yesRevstat Statistical Journal, 2014
There is a vast literature on robust estimators, but in some situations it is still not easy to make inferences, such as confidence regions and hypothesis testing. This is mainly due to the following facts.

Robust variance estimation and inference for causal effect estimation

open access: yesJournal of Causal Inference, 2023
We present two novel approaches to variance estimation of semi-parametric efficient point estimators of the treatment-specific mean: (i) a robust approach that directly targets the variance of the influence function (IF) as a counterfactual mean outcome ...

Assessment of South Pars Gas Field Subsidence Due To Gas Withdrawal [PDF]

open access: yesCivil Engineering Infrastructures Journal, 2014
Withdrawal of oil and gas from reservoirs causes a decrease in pore pressure and an increase in effective stress which results to a reservoir compaction.

Large Sample Behavior of the Least Trimmed Squares Estimator

open access: yesMathematics
The least trimmed squares (LTS) estimator is popular in location, regression, machine learning, and AI literature. Despite the empirical version of least trimmed squares (LTS) being repeatedly studied in the literature, the population version of the LTS ...

Hormonal Influences on Cognitive Function

open access: yesMalaysian Journal of Medical Sciences, 2018
This article examines how hormonal changes may affect the neuronal networking and mechanisms of cognitive function. Hormones are the chemical regulators of the human body and function critically to maintain various processes, such as growth, emotions and even cognition.

A Study on a Single Continuous Deformable Mirror for Correction of Atmospheric Disturbance [PDF]

open access: yes한국정밀공학회지, 2018
The deformable mirror is the main component of the adaptive optical imaging system, which removes the atmospheric disturbance and acquires the target image without any loss and the beam transmission system, which transmits the laser beam to a long ...
