Building with drones: Accurate 3D facade reconstruction using MAVs

Automatic reconstruction of 3D models from images using multi-view Structure-from-Motion methods has been one of the most fruitful outcomes of computer vision. These advances combined with the growing popularity of Micro Aerial Vehicles as an autonomous imaging platform, have made 3D vision tools ubiquitous for large number of Architecture, Engineering and Construction applications among audiences, mostly unskilled in computer vision. However, to obtain high-resolution and accurate reconstructions from a large-scale object using SfM, there are many critical constraints on the quality of image data, which often become sources of inaccuracy as the current 3D reconstruction pipelines do not facilitate the users to determine the fidelity of input data during the image acquisition. In this paper, we present and advocate a closed-loop interactive approach that performs incremental reconstruction in real-time and gives users an online feedback about the quality parameters like Ground Sampling Distance (GSD), image redundancy, etc on a surface mesh. We also propose a novel multi-scale camera network design to prevent scene drift caused by incremental map building, and release the first multi-scale image sequence dataset as a benchmark. Further, we evaluate our system on real outdoor scenes, and show that our interactive pipeline combined with a multi-scale camera network approach provides compelling accuracy in multi-view reconstruction tasks when compared against the state-of-the-art methods.
Early career occupational mobility of Turkish and Moroccan second-generation migrants in Flanders, Belgium

This article analyses the early career occupational mobility of people from a Turkish or Moroccan descent in Flanders (Belgium). Previous research showed that second-generation migrants are less successful than natives when entering the labour market. We compare the progress in socio-economic status (SES) that youngsters of native and non-native descent make from their first to later jobs at the start of their career. Both second-generation immigrants and native majority young adults experience upward occupational mobility during this crucial phase of their occupational career. The gap between native and ethnic minority youth, however, does not narrow over the course of the years. The first job offers less SES for non-natives compared to that of natives, and the minority-native gap in occupational attainment remains constant afterwards. The future career is largely determined by the characteristics of the start of the occupational career, and educational attainment even before. Promising, however, might be the finding that a first job with a relative low occupational status does offer better opportunities for Turkish and Moroccan second-generation migrants than for native majority youth to do some catching up later on. In combination with a long-term negative impact of initial unemployment, ethnic minority youth perhaps are best off with starting to work as soon as possible after school leaving.
Widespread pain and depression are key modifiable risk factors associated with reduced social participation in older adults

Abstract In older adults, reduced social participation increases the risk of poor health-related quality of life, increased levels of inflammatory markers and cardiovascular disease, and increased mortality. Older adults frequently present to primary care, which offers the potential to deliver interventions at the point of care to increase social participation. The aim of this prospective study was to identify the key modifiable exposures that were associated with reduced social participation in a primary care population of older adults. The study was a population-based prospective cohort study. Participants (n = 1991) were those aged ≥65 years who had completed questionnaires at baseline, and 3 and 6-year follow-ups. Generalized linear mixed modeling framework was used to test for associations between exposures and decreasing social participation over 6 years. At baseline, 44% of participants reported reduced social participation, increasing to 49% and 55% at 3 and 6-year follow-up. Widespread pain and depression had the strongest independent association with reduced social participation over the 6-year follow-up period. The prevalence of reduced social participation for those with widespread pain was 106% (adjusted incidence rate ratio 2.06, 95% confidence interval 1.72, 2.46), higher than for those with no pain. Those with depression had an increased prevalence of 82% (adjusted incidence rate ratio 1.82, 95% confidence interval 1.62, 2.06). These associations persisted in multivariate analysis. Population ageing will be accompanied by increasing numbers of older adults with pain and depression. Future trials should assess whether screening for widespread pain and depression, and targeting appropriate treatment in primary care, increase social participation in older people.
Clinical Significance and Prognostic Relevance of Microsatellite Instability in Sporadic Colorectal Cancer Patients

Microsatellite instability (MSI) is a marker of the replication error phenotype. It is caused by impaired DNA mismatch repair processes (MMR), resulting in ineffectiveness of the mechanisms responsible for the DNA replication precision and postreplicative DNA repair. MSI underlies the pathogenesis of 10%–20% of colorectal cancer (CRC) cases. The data about the potential value of MMR status as a predictive factor for 5-fluorouracil (FU)-based chemotherapy remain unclear. According to National Comprehensive Cancer Network updated guidelines, MSI testing is recommended for all patients with stage II CRC because patients with MSI-H (high-frequency MSI) tumour may have a good prognosis and obtain no benefit from 5-FU-based adjuvant chemotherapy. The significance of the MSI status as a predictive factor for patients with metastatic disease was not confirmed. The association between the MSI status and the efficacy of the therapy based on anti-programmed death-1 receptor inhibitors requires further studies.
Calibrating Data to Sensitivity in Private Data Analysis

We present an approach to differentially private computation in which one does not scale up the magnitude of noise for challenging queries, but rather scales down the contributions of challenging records. While scaling down all records uniformly is equivalent to scaling up the noise magnitude, we show that scaling records non-uniformly can result in substantially higher accuracy by bypassing the worst-case requirements of differential privacy for the noise magnitudes. This paper details the data analysis platform wPINQ, which generalizes the Privacy Integrated Query (PINQ) to weighted datasets. Using a few simple operators (including a non-uniformly scaling Join operator) wPINQ can reproduce (and improve) several recent results on graph analysis and introduce new generalizations (e.g., counting triangles with given degrees). We also show how to integrate probabilistic inference techniques to synthesize datasets respecting more complicated (and less easily interpreted) measurements.
Emotional activation in the first and second language

Late Finnish–English bilinguals were presented with neutral, positive, negative and taboo words in a modified Stroop paradigm in both Finnish and English. Significant interference from negative and taboo words compared to neutral words was found in both languages, whereas positive words were not found to differ significantly from neutral words. Furthermore, no differences in the size of the interference were present between languages. This suggests that, for late bilinguals with good knowledge of their second language, the first (L1) and second (L2) language are equally capable of activating the emotional response to word stimuli representing threat, and thus interfering with the cognitive processes involved in responding to colour. This effect was equivalent for negative and taboo words.
Introduction to Multifractal Detrended Fluctuation Analysis in Matlab

Fractal structures are found in biomedical time series from a wide range of physiological phenomena. The multifractal spectrum identifies the deviations in fractal structure within time periods with large and small fluctuations. The present tutorial is an introduction to multifractal detrended fluctuation analysis (MFDFA) that estimates the multifractal spectrum of biomedical time series. The tutorial presents MFDFA step-by-step in an interactive Matlab session. All Matlab tools needed are available in Introduction to MFDFA folder at the website www.ntnu. edu/inm/geri/software. MFDFA are introduced in Matlab code boxes where the reader can employ pieces of, or the entire MFDFA to example time series. After introducing MFDFA, the tutorial discusses the best practice of MFDFA in biomedical signal processing. The main aim of the tutorial is to give the reader a simple self-sustained guide to the implementation of MFDFA and interpretation of the resulting multifractal spectra.
Disordered visual processing and oscillatory brain activity in autism and Williams Syndrome

Two developmental disorders, autism and Williams syndrome, are both commonly described as having difficulties in integrating perceptual features, i.e. binding spatially separate elements into a whole. It is already known that healthy adults and infants display electroencephalographic (EEG) γ-band bursts (around 40 Hz) when the brain is required to achieve such binding. Here we explore γ-band EEG in autism and Williams Syndrome and demonstrate differential abnormalities in the two phenotypes. We show that despite putative processing similarities at the cognitive level, binding in Williams syndrome and autism can be dissociated at the neurophysiological level by different abnormalities in underlying brain oscillatory activity. Our study is the first to identify that binding-related γ EEG can be disordered in humans.
LINKING O*NET JOB ANALYSIS INFORMATION TO JOB REQUIREMENT PREDICTORS: AN O*NET APPLICATION

This is an exploratory study that examined the possible application of the job component validity (JCV) model to identify potential employee selection instruments and to determine job requirement levels from O*NET job analysis data, following a research paradigm established with the Position Analysis Questionnaire (PAQ). Job requirements were measured by mean aptitude test scores on the General Aptitude Test Battery (GATB), and the ratings on the O*NET Generalized Work Activities (GWAs) were selected as representative O*NET job analysis data. Multiple correlation coefficients ranging from . 35 to . 89 were found when predicting mean GATB test scores from GWAs. Similar to JCV research some 30 years ago, predictions were strongest for cognitive aptitudes and weakest for manual dexterity. The data were examined under both rational and cross-validated empirical models. The results have positive implications for the development of a database that would support JCV estimates derived from O*NET job analysis data and allow practitioners to use O*NET data to help identify useful employee selection instruments.
Challenges to Accepting a Human Papilloma Virus (HPV) Vaccine: A Qualitative Study of Australian Women

ABSTRACT A vaccine that protects women against the two most frequent high-risk genotypes of human papilloma virus (HPV) and the two types that cause 90 percent of genital warts was licensed in June 2006 in the USA and Australia. It is important to understand whether a vaccine delivered to young women before the onset of sexual activity would be acceptable. The goal of this project was to investigate the knowledge and awareness of Victorian women about cervical cancer and HPV infections, and their beliefs about, and possible barriers to, a potential vaccine. We report on findings from five focus groups, held between August and October 2005, which targeted 34 women, aged 22 to 71, from diverse backgrounds. High levels of acceptance of vaccines in general were expressed, particularly if the vaccine is recommended by health professionals and supported by the government. Reservations emerged about the proposed HPV vaccine when the link between HPV and sexual activity was understood. We offer suggestions concerning the nature of information required prior to the introduction of a vaccination program and the mechanisms by which the information can be delivered to ensure its availability to all women.
Cancer-predisposing mutations within the RING domain of BRCA1: Loss of ubiquitin protein ligase activity and protection from radiation hypersensitivity

BRCA1 is a breast and ovarian cancer-specific tumor suppressor that seems to be involved in transcription and DNA repair. Here we report that BRCA1 exhibits a bona fide ubiquitin (Ub) protein ligase (E3) activity, and that cancer-predisposing mutations within the BRCA1 RING domain abolish its Ub ligase activity. Furthermore, these mutants are unable to reverse γ-radiation hypersensitivity of BRCA1-null human breast cancer cells, HCC1937. Additionally, these mutations within the BRCA1 RING domain are not capable of restoring a G2 + M checkpoint in HCC1937 cells. These results establish a link between Ub protein ligase activity and γ-radiation protection function of BRCA1, and provide an explanation for why mutations within the BRCA1 RING domain predispose to cancer. Furthermore, we propose that the analysis of the Ub ligase activity of RING-domain mutations identified in patients may constitute an assay to predict predisposition to cancer.
Satisfaction–Adaptation Principles in Sexual Desire

Sexual desire may change according to two principles: the satisfaction principle (high sexual opportunity/frequency decreases sexual desire) and the adaptation principle (high sexual opportunity/frequency increases sexual desire). We explore the workings of these opposing principles separately for both genders across the adult life span. Two tests within a large (N = 181,546) and cross-cultural (11 countries) data set revealed that the satisfaction principle accounts for sexual desire in men throughout the entire life and it accounts for sexual desire in women until their mid-30s. From that point onward, however, the pattern of female sexual desire becomes increasingly consistent with the adaptation principle. What sets older women apart from younger women and men of all ages? We discuss several mechanisms, with a focus on the satisfaction principle’s evolutionary value in life phases of high reproductive capacity and the adaptation principle’s evolutionary value in life phases of low reproductive capacity.
xCITED2 Induces Neural Genes in Animal Cap Explants of Xenopus Embryos

Neural tissue is arisen from presumptive ectoderm via inhibition of bone morphogenetic protein (BMP) signaling during Xenopus early development. Previous studies demonstrate that ectopic expression of dominant negative BMP4 receptor (DNBR) produces neural tissue in animal cap explants (AC) and also increases the expression level of various genes involved in neurogenesis. To investigate detail mechanism of neurogenesis in transcriptional level, we analyzed RNAs increased by DNBR using total RNA sequencing analysis and identified several candidate genes. Among them, xCITED2 (Xenopus CBP/p300-interacting transcription activator) was induced 4.6 fold by DNBR and preferentially expressed in neural tissues at tadpole stage. Ectopic expression of xCITED2 induced anterior neural genes without mesoderm induction and reduced BMP downstream genes, an eye specific marker and posterior neural marker. Taken together, these results suggest that xCITED2 may have a role in the differentiation of anterior neural tissue during Xenopus early development.
Short-time homomorphic wavelet estimation

Successful wavelet estimation is an essential step for seismic methods like impedance inversion, analysis of amplitude variations with offset and full waveform inversion. Homomorphic deconvolution has long intrigued as a potentially elegant solution to the wavelet estimation problem. Yet a successful implementation has proven difficult. Associated disadvantages like phase unwrapping and restrictions of sparsity in the reflectivity function limit its application. We explore short-time homomorphic wavelet estimation as a combination of the classical homomorphic analysis and log-spectral averaging. The introduced method of log-spectral averaging using a short-term Fourier transform increases the number of sample points, thus reducing estimation variances. We apply the developed method on synthetic and real data examples and demonstrate good performance.
Speaking the Unspeakable: Exploring the Impact of Family Dynamics on Child Sexual Abuse Disclosures

This qualitative study utilized the long interview method to identify a range of family dynamics that may affect a child's ability to disclose sexual abuse. It is estimated that 30% to 80% of victims do not purposefully disclose child sexual abuse (CSA) before adulthood. Retrospective data about disclosure processes were elicited through interviews with 20 male and female CSA survivors. Four major themes emerged suggesting that CSA disclosure can be significantly compromised when certain conditions exist: rigidly fixed, gender roles based on a patriarchy-based family structure; family violence; closed, indirect communication patterns; and social isolation. It is important to identify disclosure barriers in order to ameliorate them effectively, because when children are not able to disclose sexual abuse, the effects are potentially devastating. Results are discussed in relation to implications for practice with children and their families, including relevance of established models of family assessment.
Understanding and Predicting Question Subjectivity in Social Question and Answering

The explosive popularity of social networking sites has provided an additional venue for online information seeking. By posting questions in their status updates, more and more people are turning to social networks to fulfill their information needs. Given that understanding individuals' information needs could improve the performance of question answering, in this paper, we model the task of intent detection as a binary classification problem, and thus for each question, two classes are defined: subjective and objective. We use a comprehensive set of lexical, syntactical, and contextual features to build the classifier and the experimental results show satisfactory classification performance. By applying the classifier on a larger dataset, we then present in-depth analyses to compare subjective and objective questions, in terms of the way they are being asked and answered. We find that the two types of questions exhibited very different characteristics, and further validate the expected benefits of differentiating questions according to their subjectivity orientations.
Restrictive Safety or Unsafe Freedom? Norwegian ECEC Practitioners' Perceptions and Practices Concerning Children's Risky Play

Many countries face a growing debate on the balance between ensuring children's safety and allowing children to play in physically and emotionally stimulating and challenging environments. This study is theoretically and conceptually situated within this debate, focusing on how early childhood education and care (ECEC) practitioners perceive the risk in children's play, and how they handle children's physical risk-taking given their dual responsibilities to keep children safe and to provide enough developmental challenges. Qualitative semi-structured interviews were conducted with seven ECEC practitioners with the goal of gaining insight into their opinions and reflections on children's risky play in kindergarten. The results show that Norwegian ECEC practitioners assess children's opportunities to engage in risky play in kindergarten as good: play environments provide opportunities for risky play, and practitioners allow and encourage children's risky play. The practitioners have a positive attitude toward risky play and state that they think it is important for children's development. The interviews show that the strategies for handling risky play are adapted instinctively in the play situation, considering each child individually, and common boundaries or rules are rare. The results of this study are a contribution to the discussion on children's play safety and how to handle risk-taking play in ECEC settings, and would hopefully be inspiring to ECEC practitioners and politicians in countries other than Norway.
Purinergic control of vascular tone in the retina

The blood supply to the CNS is controlled by the tone of arteries and arterioles. However, little is known about purinergic regulation of vascular tone in the CNS. We have investigated purinergic control of vascular tone in the in vivo rat retina. Reducing endogenous ATP levels by enzyme degradation and inhibiting purinergic signalling with P2X receptor antagonists decreases the tone of retinal arterioles. Raising ATP levels increases vessel tone. Experiments using fluorocitrate to poison the metabolism of glial cells suggest glia are a source of the ATP that tonically constricts retinal vessels. The results suggest a novel mechanism of local control of vascular tone through activation of vascular smooth muscle cell P2X receptors.
Erythrocyte Glutathione, Glutathione Peroxidase, Superoxide Dismutase and Serum Lipid Peroxidation in Epileptic Children With Valproate and Carbamazepine Monotherapy

This prospective study was carried out to determine changes in the antioxidant system in epileptic children receiving long term antiepileptic drugs (AEDs). Levels of erythrocyte glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and serum lipid peroxidation were determined in 25 healthy children and 30 epileptic children who had not yet received AEDs. Sixteen patients were treated with valproic acid (VPA) and 14 with carbamazepine (CBZ); 13 months later these parameters were retested. The results showed that SOD and lipid peroxidation levels were increased but the GSH-Px levels were decreased in epileptic children on VPA therapy compared with the control group and the results before treatment. No significant differences of these parameters were found in epileptic children on CBZ therapy compared with the control group and the results before treatment, except that lipid peroxidation level was slightly higher in epileptic patients before treatment. We conclude that antioxidant systems in epileptic children on CBZ therapy are better regulated in comparison with epileptic children on VPA therapy.
Mapping Images to Sentiment Adjective Noun Pairs with Factorized Neural Nets

We consider the visual sentiment task of mapping an image to an adjective noun pair (ANP) such as "cute baby". To capture the two-factor structure of our ANP semantics as well as to overcome annotation noise and ambiguity, we propose a novel factorized CNN model which learns separate representations for adjectives and nouns but optimizes the classification performance over their product. Our experiments on the publicly available SentiBank dataset show that our model significantly outperforms not only independent ANP classifiers on unseen ANPs and on retrieving images of novel ANPs, but also image captioning models which capture word semantics from co-occurrence of natural text; the latter turn out to be surprisingly poor at capturing the sentiment evoked by pure visual experience. That is, our factorized ANP CNN not only trains better from noisy labels, generalizes better to new images, but can also expands the ANP vocabulary on its own.
