Why Distinguish Between Statistics and Mathematical Statistics–The Case of Swedish Academia

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why has it been kept for so long in Sweden, and what consequences may it have had?In May 2015, it was 100 years since Mathematical Statistics was formally established as an aA separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors.

Gaussian integrals and Rice series in crossing distributions : to compute the distribution of maxima and other features of Gaussian processes

We describe and compare how methods based on the classicalRice’s formula for the expected number, and higher moments, of level crossingsby a Gaussian process stand up to contemporary numerical methods toaccurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Ricemoment methods and the exact numerical method, We describe and compare how methods based on the classical Rice’s formula for the expected number, and higher moments, of level crossings by a Gaussian process stand up to contemporary numerical methods to accurately deal with crossing related characteristics of the sample paths.We illustrate the relative merits in accuracy and computing time of the Rice moment methods and the exact numerical meth

Craniopharyngioma. Morbidity and Structural Changes in the Brain

Hypothalamus (HT) is a brain structure which serves as a coordination center for several vital body functions. Craniopharyngioma (CP) is a pituitary tumor with high morbidity, primarily due to HT lesion. Among important consequences of CP are cognitive dysfunction and intractable weight gain due to HT obesity, resulting in high cardiovascular (CV) risk. A better understanding of the structural bra

Nanoscale quantum calorimetry with electronic temperature fluctuations

Motivated by the recent development of fast and ultrasensitive thermometry in nanoscale systems, we investigate quantum calorimetric detection of individual heat pulses in the sub-meV energy range. We propose a hybrid superconducting injector-calorimeter setup, with the energy of injected pulses carried by tunneling electrons. It is shown that the superconductor constitutes a versatile injector, w

Being acknowledged by others and bracketing negative thoughts and feelings : Frail older people’s narrations of how existential loneliness is eased

Aims and objectives: The aim of this study was to describe how EL was eased, as narrated by frail older people. Background: Existential loneliness (EL) is an unavoidable part of the human condition. It is a complex phenomenon that has been described as disconnection from life. If EL is acknowledged in the care of older people, the experience of EL can be reduced. Design: In this qualitative study,

Predictive Pressure Control with Multiple Injections

This paper introduces a predictive combustion-engine controller for efficient fulfillment of constraints on peak pressure, exhaust temperature and NO emissions. The controller utilizes a in-cylinder pressure sensor, actuation of multiple fuel injections and numerical optimization. A physical model is used to predict pressure changes due to fuel-injection variation. The predicted pressure is used t
