In this paper, we propose a gridless method for estimating an unknown number of fundamental frequencies. Starting with a conventional dictionary matrix, containing sets of candidate fundamental frequencies and their corresponding harmonics, a non-convex log-sum cost function is formed such that it imposes the harmonic structure and treats every fundamental frequency in the dictionary as a paramete
We examine how the gender of a sibling affects earnings, education and family formation. Identification is complicated by parental preferences: if parents prefer certain sex compositions over others, children's gender affects not only the outcomes of other children but also the existence of potential additional children. We employ two empirical strategies that both address this problem. First, we
A number of studies show that when doctors become ill, there is often ambiguity in the division of roles and responsibilities in the medical encounter. Yet little is known about how the dilemma of the sick doctor has changed over time. This article explores the experience of illness among physicians by applying an historical, narratological approach to three doctor’s narratives about personal case
According to the Global Burden of Disease study, occupational exposures to particulates, gases and fumes were responsible for 0.36 million deaths and 8.8 million disability-adjusted life years globally in 2015. This thesis focuses on two occupational groups that are at risk for developing adverse health effects from the time they spend in their working environments: cleaning workers and workers in
Drawing on ethnographical work at the Swedish Public Employment Service, this article contextualizes functional stupidity in relation to other types of organizational compliance. Rather than seeing stupidity as a personality trait, I argue that it should be regarded as a transient unreflective mode of compliance one may yield to for a number of reasons but also reflect on in hindsight. Based on th
Long-term genetic data from intensively monitored natural populations are important for understanding how effective population sizes (N e) can vary over time. We therefore genotyped 1622 common buzzard (Buteo buteo) chicks sampled over 12 consecutive years (2002-2013 inclusive) at 15 microsatellite loci. This data set allowed us to both compare single-sample with temporal approaches and explore te
This chapter introduces an ancient perspective on literary style and applies it to parts of the Fourth Gospel. Rather than using stylistic features to indicate authorship, sources, or redaction, this chapter focuses upon how style affects how the content (and story) of the Fourth Gospel is understood. In antiquity, stylistic features conveyed information about the mood, focus, and interpretation o
Nanoscale plasmonic systems combine the advantages of optical frequencies with those of small spatial scales, circumventing the limitations of conventional photonic systems by exploiting the strong field confinement of surface plasmons. As a result of this miniaturization to the nanoscale, electron microscopy techniques are the natural investigative methods of choice. Recent years have seen the de
Purpose The cortical characteristics of the iliac crest in male have rarely been investigated with quantitative histomorphometry. Also it is still unknown how cortical microarchitecture may vary between the iliac crest and fractures related sites at the proximal femur. We studied the microarchitecture of both external and internal cortices within the iliac crest, and compared the results with femo
Cells, the basic units of living organisms, are well delineated and separated from the external environment by membranes. Capable of both enclosing the cellular constituents and allowing exchanges with the outside world, these membranes are only a few nanometers thick. All the membranes in a human body cover an area of a few hectares, but account for only a small part of our mass. To study the dyn
Among the existing estimators of interactive effects (IEs) regressions, the common correlated effects (CCE) approach is probably the most popular. A major reason for this popularity is the generality of the approach. In fact, CCE is remarkably general in that it allows ample parameter heterogeneity without placing any restrictions on the true number of common factors. In the present paper, we show
AIMS: Some 15% of the Swedish population is born outside Sweden, originating from all continents of the world. Thalassemia and sickle cell anemia constitute the most common inherited recessive disorders globally and they are endemic in areas of Africa and Asia, origins of many immigrants to Sweden. We aimed at investigating the origins of the Swedish sickle cell and thalassemia patients.METHODS: P
In this article we present a new method for visual face tracking that is carried out in wavelet subspace. Firstly, a waveletre presentation for the face template is created, which spans a low dimensional subspace of the image space. The wavelet representation of the face is a point in this wavelet subspace. The video sequence frames in which the face is tracked are orthogonally projected into this
Directed relation graph with error propagation (DRGEP) method combined with extensive validation for 0D, 1D and 2D CFD modeling supported by sensitivity and Rate-Of-Production (ROP) analyses are implemented for comparative study of detailed and reduced kinetic mechanisms for CH 4
Background: Dermatitis caused by occupational contact allergy to rubber additives such as diphenylguanidine (DPG) in medical gloves is a hazard for healthcare workers. Both the duration of exposure to medical gloves and the number of gloves used per day vary. The use of alcoholic skin disinfectants before glove donning is mandatory. Objectives: To assess whether skin exposure to the rubber acceler
