In this paper, we revisit the classical perspective-n-point (PnP) problem, and propose the first non-iterative O(n) solution that is fast, generally applicable and globally optimal. Our basic idea is to formulate the PnP problem into a functional minimization problem and retrieve all its stationary points by using the Gr¨obner basis technique. The novelty lies in a non-unit quaternion representati

With their potential to effectively address multiple urban sustainability challenges, the emerging policy discourse on nature-based solutions seeks to encourage the development of multifunctional nature for sustainable and just cities. Nature-based solutions, however, are vulnerable to co-option by powerful interests in ways that limit their contribution to a broad range of sustainability goals.

Both studies on animals and humans have demonstrated the role of inflammatory mediators on the retinopathy process.2,3 Dexamethasone is a glucocorticoid with a known reductive effect on several of these mediators and on the expression of VEGF.4Starting in 2016, infants receiving laser ablation for type 1 ROP at Skåne University Hospital were administered dexamethasone eye-drops postoperatively, us

Millimeter-Wave (mmWave) massive multiple-input multiple-output (MIMO) has been considered as a key enabler for the fifth-generation (5G) communications. It is essential to design and test mmWave 5G devices under various realisticscenarios since the radio propagation channels pose intrinsic limitations on the performance. This requires emulating realistic dynamic mmWave channels in a reproducible

This essay takes its point of departure in a letter written by Ayatollah Khomeini suggesting that sovereign authority is a matter of “absolute divine guardianship” and that the state “may suspend any matter – be it devotional or non-devotional – when it contravenes the best interests of Islam for the duration that it is so”. Khomeini insistence that the Islamic state headed by a Guardian Jurist is

BACKGROUND: The mechanisms of association between diabetes and inner ear dysfunction are unknown, although endolymphatic hydrops may be involved. We have previously shown that insulin signaling components are expressed in human saccule and that insulin signaling takes place in HEI-OC1 auditory cells.AIM: To explore Nedd4-2 as a target for insulin signaling.MATERIALS AND METHODS: Effects of insulin

The main objective was to develop a wipe sampling test to measure surface contamination of the most frequently used antineoplastic drugs (ADs) in Swedish healthcare and, furthermore, to develop an analysis method sensitive enough to assess low levels of contamination. Two wipe sampling tests with separate sample processing methods assessing (i) cyclophosphamide (CP), ifosfamide (IF), 5-fluorouraci

This article surveys the reception of the Gnostic text Pistis Sophia in esoteric milieus in nineteenth- and early twentieth-century Europe. The first part of the article contains an overview of the text and scholarship on it. Then follows a study of the reception of Pistis Sophia in a broader array of esoteric circles. It becomes clear that the text was hailed as an example of ancient and great spThis article surveys the reception of the Gnostic text Pistis Sophia in esoteric milieus in nineteenth- and early twentieth-century Europe.

Despite urgent need for climate action, denial of climate change and resulting absence of appropriate pro-environmental behavior are widespread. Interpretive (recognition of climate change as a problem but re-interpretation of its severity) and implicatory denial of climate change (recognition of climate change as a problem but denial of psychological, political, and moral implications) can be int

Twin studies are widely used to estimate heritability of traits and typically rely on knowing the zygosity of twin pairs in order to determine variation attributable to genetics. Most twin studies are conducted in high resource settings. Large scale household survey data, such as the Demographic and Health Surveys, collect various biomarkers for children under five years old in low- and middle-inc

Increasing iron (Fe) concentrations are found in lakes on a wide geographical scale but exact causes are still debated. The observed trends might result from increased Fe loading from the terrestrial catchment, but also from changes in how Fe distributes between the water column and the sediments. To get a better understanding of the causes we investigated whether there has been any change in the

INTRODUCTION: Informal carers in paid employment-working carers (WKCs)-have complex support needs. However, little is known about WKCs' pattern of informal care provision, the support they receive, the impact providing care has on their employment, and how these vary between male and female WKCs. This study describes the pattern of informal care provision and received support among Swedish WKCs.RE

Several groups have during past years produced molecular classification schemes for bladder cancer. Even though no consensus on how to define a subtype exists, one approach has been to base definitions on how tumours cluster according to their mRNA expression profiles. In many cases, obtained profiles, and thus class defining features, are affected by signals from non-tumour cells within the biops

A feasible implementation of a novel X-ray detector for highly energetic X-ray photons with a large solid angle coverage, optimal for the detection of Compton X-ray scattered photons, is described. The device consists of a 20 cm-thick sensitive volume filled with xenon at atmospheric pressure. When the Compton-scattered photons interact with the xenon, the released photoelectrons create clouds of

Aim: The study aim was to evaluate the RSR 3 Screen ICA™ and 2 Screen ICA™ for detection of islet cell autoimmunity in healthy Swedish subjects and patients with newly diagnosed type 1 diabetes (T1D). Methods: 3 Screen is designed for combined detection of autoantibodies to glutamic acid decarboxylase (GADA), to the islet antigen IA-2 (IA-2A) and to zinc transporter 8 (ZnT8A), while 2 Screen detec
