ROBUST ROTATION AND TRANSLATION ESTIMATION IN STRUCTURE FROM MOTION

Due to advances in technology the amount of images from portable cameras has increased tremendously in recent years. Nowadays, most new mobile phones and cars have multiple cameras. Drones and other robots are often equipped with cameras as well. To be able to capture an image is not the same as to understand the content of it. Computer vision deals with the task of giving machines the ability to

Follow up with HPV test and cytology as test of cure, 6 months after conization, is reliable

Introduction: Human papillomavirus (HPV) infection is an objective marker with a high sensitivity for finding cervical dysplasia. The objective of the current study is to investigate whether HPV testing, combined with liquid-based cytology, is reliable as a test of cure after the loop electrical excision procedure (LEEP). Material and methods: The LEEP was performed in 330 women for excision of ce

Development and Application of Optical Diagnostics of Alkali Vapours for Solid Fuel Combustion

Background: High amounts of alkali in the fuel, such as potassium and sodium in combination with high amounts of chlorine increase the chances of high-temperature corrosion, deposit growth and slagging and fouling. These risks need to be reduced to avoid losses in revenue due to unplanned stops and costs related to increased maintenance. Aims:This research targets the development of a new cell to

A molecular phylogeny for the oldest (nonditrysian) lineages of extant Lepidoptera, with implications for classification, comparative morphology and life-history evolution

Within the insect order Lepidoptera (moths and butterflies), the so-called nonditrysian superfamilies are mostly species-poor but highly divergent, offering numerous synapomorphies and strong morphological evidence for deep divergences. Uncertainties remain, however, and tests of the widely accepted morphological framework using other evidence are desirable. The goal of this paper is to test previ

Relationships within the Melitaea phoebe species group (Lepidoptera: Nymphalidae) : new insights from molecular and morphometric information

The genus Melitaea consists of about 80 species, divided into ten species groups, which are all restricted to the Palaearctic region. The Melitaea phoebe group was defined by Higgins based on morphological characters such as wing pattern and genital structures. According to his interpretation, the M.phoebe group included seven species: M.phoebe, M.sibina, M.scotosia, M.aetherie, M.collina, M.consu

Notable plesiomorphies and notable specializations : Head structure of the primitive "tongue moth" Acanthopteroctetes unifascia (lepidoptera: Acanthopteroctetidae)

The Acanthopteroctetidae are one of the first-originated family-group lineages within "tongue moths" (Lepidoptera-Glossata). The purpose of this study is to provide a comprehensive account (based on whole mount preparations, serial sections, and Scanning electron microscopy) of the cephalic structure of an adult exemplar of the family, to supplement the sparse available information. Notable plesio

Choreutidae of Madeira : Review of the known species and description of the male of Anthophila threnodes (Walsingham, 1910) (Lepidoptera)

We review and illustrate the four species of Choreutidae recorded from Madeira - Anthophila threnodes (Walsingham), A. fabriciana (Linnaeus), Choreutis nemorana (Hubner), and Tebenna micalis (Mann) - and describe and illustrate for the first time the male of A. threnodes, as well as the biology of this Madeiran endemic. We provide brief notes on each of the species and give short diagnoses for cor

A new genus of metalmark moths (Lepidoptera, Choreutidae) with Afrotropical and Australasian distribution

Niveas Rota, new genus, and its two new species, N. agassizi Rota, new species, and N. kone Rota, new species, are described and illustrated. Niveas is assigned to the subfamily Choreutinae based on morphological and molecular data. Niveas agassizi is currently known only from Kenya and only from female specimens. Niveas kone has been found on the Solomon Islands and in Papua New Guinea (PNG). In

Exploration of data partitioning in an eight-gene data set : Phylogeny of metalmark moths (Lepidoptera, Choreutidae)

Molecular data sets for phylogenetic inference continue to increase in size, especially with respect to the number of genes sampled. As more and more genes are included in analyses, the importance of partitioning the data to avoid problems that can arise from underparameterization becomes more apparent. With an eight-gene data set from 38 metalmark moth species (12 genera represented) and three ou

Variation in the female frenulum in tortricidae (Lepidoptera). Part 3. Tortricinae

This paper, treating the subfamily Tortricinae, represents the third and final contribution in the three-part series examining variation in the number of bristles in the female frenulum of tortricid moths. Based on the examination of 3,850 females of 1,082 species from 267 genera, the number of bristles in females varies from one to eight and frequently is asymmetrical on the same specimen (19% of

Tortricid moths reared from the invasive weed Mexican palo verde, Parkinsonia aculeata, with comments on their host specificity, biology, geographic distribution, and systematics

As part of efforts to identify native herbivores of Mexican palo verde, Parkinsonia aculeata L. (Leguminosae: Caesalpinioideae), as potential biological control agents against this invasive weed in Australia, ten species of Tortricidae (Lepidoptera) were reared from Guatemala, Mexico, Nicaragua, and Venezuela: Amorbia concavana (Zeller), Platynota rostrana (Walker), Platynota helianthes (Meyrick),

Data partitioning in Bayesian analysis : Molecular phylogenetics of metalmark moths (Lepidoptera: Choreutidae)

In this study a multilocus phylogenetic analysis of metalmark moths (Lepidoptera: Choreutidae) focused on resolving the higher-level phylogeny of this group is presented. Through the analysis of this dataset, I explore different data-partitioning strategies in Bayesian phylogenetic inference, and find that a partitioning strategy can have a large influence on the results of phylogenetic analysis.

Variation in the female frenulum in Tortricidae (Lepidoptera). Part 2. Olethreutinae

This paper, treating the tortricid subfamily Olethreutinae, represents the second in a proposed three-part series examining variation in the number of bristles in the frenulum of female tortricid moths. Based on an examination of 6,333 individuals of 1,464 species representing 188 genera of Olethreutinae, the number of bristles in the female frenulum varies from one to six, and it is sometimes asy

A new genus and species of Grapholitini (Lepidoptera, Tortricidae) from Florida, U.S.A

Riculorampha ancyloides Rota & Brown, gen. n., sp. n. from Florida, is described and illustrated. The type series was reared from the fruit of redbay, Persea borbonia (Lauraceae). The new genus is assigned provisionally to the Dichrorampha-group of genera (Grapholitini) on the basis of the following characters: forewing termen with a row of black dots, forewing fringe with a shallow subapical

A new genus and new species of metalmark moths (Lepidoptera : Choreutidae) from Costa Rica

Alasea, new genus, is described and illustrated. As currently defined, Alasea is monotypic with the single species A. corniculata, n. sp., from Heredia, Limón, and Puntarenas provinces in Costa Rica. The new genus is assigned to the subfamily Choreutinae based on morphological and molecular data. As in other choreutines, Alasea has a bluntly pointed forewing and hindwing (in Brenthiinae the wings

Law, Materiality & Justice

Can law still play a central role in governing human behavior even if the state law may have become less important? Whether law without the state is possible depends, of course, on how we define “law” and “state”. But it also depends on the perspective from which one approaches the legal material. From a sociology of law perspective, as will be presented in this chapter, the topic has a slightly d
