A Constructivist View of Newton’s Mechanics

In the present essay we attempt to reconstruct Newtonian mechanics under the guidance of logical principles and of a constructive approach related to the genetic epistemology of Piaget and García (Psychogenesis and the history of science, Columbia University Press, New York, 1989). Instead of addressing Newton’s equations as a set of axioms, ultimately given by the revelation of a prodigious mind,

Extreme diversification of floral volatiles within and among species of Lithophragma (Saxifragaceae)

A major challenge in evolutionary biology is to understand how complex traits of multiple functions have diversified and codiversified across interacting lineages and geographic ranges. We evaluate intra- and interspecific variation in floral scent, which is a complex trait of documented importance for mutualistic and antagonistic interactions between plants, pollinators, and herbivores. We perfor

The city, the church, and the 1960s : On secularization theory and the Swedish translation of Harvey Cox’s The Secular City

In 1994, sociologist of religion José Casanova wrote in the introduction to his influential book Public Religions in the Modern World that a paradigm shift had occurred in his field. His colleagues had abandoned an earlier paradigm “with the same uncritical haste with which they previously embraced it.” 1 What he had in mind was the theory of secularisation: that is, the notion that with modernisa

Nuclear spectroscopy with GEANT4 : The superheavy challenge

The simulation toolkit Geant4 was originally developed at CERN for high-energy physics. Over the years it has been established as a swiss army knife not only in particle physics but it has seen an accelerated expansion towards nuclear physics and more recently to medical imaging and y- and ion-therapy to mention but a handful of new applications. The validity of Geant4 is vast and large across man

Validation of new superheavy elements and IUPAC-IUPAP joint working group

The great chemist Glenn Seaborg has written a delightful little book "Man-made Transuranium Elements", published in 1963, in which he points out that: "The former basic criterion for the discovery of a new element - namely, chemical identification and separation from all previously-known elements - had to be changed in the case of lawrencium (element 103). This also may be true for elements beyond

Health-related quality of life in patients with lymphoedema - a cross-sectional study

Introduction: Lymphoedema may cause complex problems that can strongly influence patients' health-related quality of life (HRQoL). The main purpose of this study was to investigate the impact of lymphoedema on HRQoL in patients with varying forms of lymphoedema. Methods: The Lymphoedema Quality of Life Inventory (LyQLI), measuring three domains, physical, psychosocial and practical, and the Short

Event Based Control

In spite of the success of traditional sampled-data theory in computer control it has some disadvantages particularly for distributed, asynchronous, and multi-rate system. Event based sampling is an alternative which is explored in this paper. A simple example illustrates the differences between periodic and event based sampling. The architecture of a general structure for event based control is p

Learned response sequences in cerebellar Purkinje cells

Associative learning in the cerebellum has previously focused on single movements. In eyeblink conditioning, for instance, a subject learns to blink at the right time in response to a conditional stimulus (CS), such as a tone that is repeatedly followed by an unconditional corneal stimulus (US). During conditioning, the CS and US are transmitted by mossy/parallel fibers and climbing fibers to cere

The Creation of Transnational Memory Spaces : Professionalization and Commercialization

In the age of globalization, local memories of past violence are often dislocated from their material places as remembrance is transpiring in transnational memory spaces. Historical events and commemorative memory practices increasingly transcend national boundaries and change the way memories of historical violence, atrocity, and genocide are represented in the transnational memoryscape. This art

Anaphoric reference to quantified expressions in Swedish

This paper presents the results from two studies on anaphoric reference to quantifying expressions (QEs) in Swedish, contributing to the current cross-linguistic discussion on this issue. For English it has been shown that the polarity of the QE (positive vs negative) determines the anaphoric set reference (to the referens set, REFSET, or to the complement set, COMPSET), while for Spanish it has b

Estimation of event related potentials

A study is done concerning event related potentials in coloured noise, such as evoked potential signals (EP) in EEG. Two estimators, both based on the least square version of the Prony method, combined with singular value decomposition, have been investigated. The EP is described by a sum of damped sinusoids in both estimators. In the first estimator the noise is described by an ARMA—process and in

Decision support for bridge condition assessment

The paper presents the first steps of the development of a theoretical framework for a rational yet practical decision making process concerning the condition assessment of existing bridges in Sweden. The main focus is on how to choose the appropriate level of enhanced conditions assessment considering aspects of model sophistication, uncertainty consideration and knowledge content utilisation. A
