Real-Time Multi-person Motion Capture from Multi-view Video and IMUs
Authors: Malleson Charles , Collomosse John , Hilton Adrian 
Published: December 2019

AbstractA real-time motion capture system is presented which uses input from multiple standard video cameras and inertial measurement units (IMUs). The system is able to track multiple people simultaneously and requires no optical markers, specialized infra-red cameras or foreground/background segmentation, making it applicable to general indoor and outdoor scenarios with dynamic backgrounds and lighting. To overcome limitations of prior video or IMU-only approaches, we propose to use flexible combinations of multiple-view, calibrated video and IMU input along with a pose prior in an online optimization-based framework, which allows the full 6-DoF motion to be recovered including axial rotation of limbs and drift-free global position. A method for sorting and assigning raw input 2D keypoint detections into corresponding subjects is presented which facilitates multi-person tracking and rejection of any bystanders in the scene. The approach is evaluated on data from several indoor and outdoor capture environments with one or more subjects and the trade-off between input sparsity and tracking performance is discussed. State-of-the-art pose estimation performance is obtained on the Total Capture (mutli-view video and IMU) and Human 3.6M (multi-view video) datasets. Finally, a live demonstrator for the approach is presented showing real-time capture, solving and character animation using a light-weight, commodity hardware setup.

Published: December 2019

AbstractFeature matching aims at generating correspondences across images, which is widely used in many computer vision tasks. Although considerable progress has been made on feature descriptors and fast matching for initial correspondence hypotheses, selecting good ones from them is still challenging and critical to the overall performance. More importantly, existing methods often take a long computational time, limiting their use in real-time applications. This paper attempts to separate true correspondences from false ones at high speed. We term the proposed method (GMS) grid-based motion Statistics, which incorporates the smoothness constraint into a statistic framework for separation and uses a grid-based implementation for fast calculation. GMS is robust to various challenging image changes, involving in viewpoint, scale, and rotation. It is also fast, e.g., take only 1 or 2 ms in a single CPU thread, even when 50K correspondences are processed. This has important implications for real-time applications. What’s more, we show that incorporating GMS into the classic feature matching and epipolar geometry estimation pipeline can significantly boost the overall performance. Finally, we integrate GMS into the well-known ORB-SLAM system for monocular initialization, resulting in a significant improvement.

Published: December 2019

AbstractData on the KIT mutation rate in melanoma in the central European region is missing. Accordingly, in a cohort of 79 BRAF/NRAS double wild type cutaneous melanoma and 17 mucosal melanoma KIT mutation was assessed by Sanger sequencing of exons 9,11,13,17 and 18. In this cutaneous melanoma cohort KIT mutation frequency was found to be 34/79 (43.04%) with a significantly higher rate in acrolentiginous melanoma (ALM) as compared to UV-induced common variants (20/34, 58.8% versus 14/45, 31.1%,p = 0.014). In the double wild type mucosal melanoma cohort the KIT mutation frequency was found to be comparable (41.2%). The actual frequency of KIT mutation in the original 227 patient cutaneous melanoma cohort was 34/227, 14.9%. Exon 11 was the most frequent mutation site (44.7%) followed by exon 9 (21.1%) equally characterizing UV-induced common histotypes and ALM tumors. In mucosal melanoma exon 9 was the most frequently involved exon followed by exon 13 and 17. KIT mutation hotspots were identified in exon 9 (c482/491/492), in exon 11 (c559,c572, c570), in exon 13 (c642), in exon 17 (c822) and in exon 18 (c853). The relatively high KIT mutation rate in cutaneous melanoma in this central-European cohort justifies regular testing of this molecular target in this entity, not only in mucosal variants.

AbstractOdontoblasts act as dentin formation and sensory receptors. Recently, it was reported that transient receptor potential ankyrin (TRPA) 1, TRP vanilloid (TRPV) 4 and pannexin 1 (PANX-1) play important roles in odontoblast sensory reception. However, it is not known when odontoblasts begin to possess a sense reception function. The aim of this study was to clarify the development of odontoblasts as sense receptors. Sections of mandibular first molars from postnatal day (PN) 0 to PN12 Wistar rats were prepared for hematoxylin–eosin staining. Immunohistochemically, we used anti-dentin sialoprotein (DSP), anti-TRPA1, anti-TRPV4, anti-PANX-1, and anti-neurofilament (NF) antibodies. In addition, we investigatedTRPA1andTRPV4expression by reverse transcriptional quantitative polymerase chain reaction (RT-qPCR). At PN0, undifferentiated odontoblasts showed no immunoreaction to anti-DSP, anti-TRPA1, anti-TRPV4, or anti-PANX-1 antibodies. However, immunopositive reactions of these antibodies increased during odontoblast differentiation at PN3 and PN6. An immunopositive reaction of the anti-NF antibody appeared in the odontoblast neighborhood at PN12, when the odontoblasts began to form root dentin, and this appeared later than that of the other antibodies. By RT-qPCR, expression ofTRPA1at PN6 was significantly lower than that at PN0 (p < 0.05) and PN3 (p < 0.01). Expression ofTRPV4at PN6 was significantly lower than that at PN0 (p < 0.01) and PN3 (p < 0.01). The results of this study suggest that odontoblasts may acquire sensory receptor function after beginning to form root dentin, when TRPA1, TRPV4, PANX-1 channels, and nerve fibers are completely formed.

AbstractThe aim of this study is to examine and evaluate several dye/amine systems as photoinitiators for photopolymerization of 2-hydroxyethyl acrylate (HEA) monomer under visible light conditions. For this purpose, a series of dye/amine photoinitiators were formed using methylene blue (MB) or acridine orange (AO) as photosensitizers, and triethanolamine (TEOA), ethyl 4-(dimethylamino) benzoate (EDMAB), trioctylamine (TOA), and N,N-diméthylallylamine (DMAA) as co-initiators. The photopolymerization kinetic of the HEA monomer in the presence of proposed dye/amine systems was performed using Fourier-transform infrared spectroscopy (FTIR) analysis and the synergetic effect of the dye/amine photoinitiators systems on the photopolymerization efficiency was examined. Interestingly, (MB/EDMAB) system shows the better reactivity with a total conversion of HEA monomer.

AbstractIntroductionPreventing dementia, or modifying disease course, requires identification of presymptomatic or minimally symptomatic high‐risk individuals.MethodsWe used longitudinal electronic health records from two large academic medical centers and applied a validated natural language processing tool to estimate cognitive symptomatology. We used survival analysis to examine the association of cognitive symptoms with incident dementia diagnosis during up to 8 years of follow‐up.ResultsAmong 267,855 hospitalized patients with 1,251,858 patient years of follow‐up data, 6516 (2.4%) received a new diagnosis of dementia. In competing risk regression, an increasing cognitive symptom score was associated with earlier dementia diagnosis (HR 1.63; 1.54–1.72). Similar results were observed in the second hospital system and in subgroup analysis of younger and older patients.DiscussionA cognitive symptom measure identified in discharge notes facilitated stratification of risk for dementia up to 8 years before diagnosis.
Changes to extended validation indicators put users at risk
Authors: Callan Tim , Bailey Chris 
Published: December 2019

In 2019, both Google and Mozilla declared their intentions to remove distinctive extended validation (EV) certificate indicators from their browsers – indicators that tell consumers that a website has been vetted and validated through a thorough authentication process. At a time where the push towards increased consumer privacy exists on a global scale, with the US Congress proposing a handful of bills on the matter, and the General Data Protection Regulation (GDPR) taking effect in the European Union, these changes to Chrome and Firefox browsers seem to be a step in the opposite direction. Consumer privacy suffers in the absence of strong website identity. At a time where there's a push towards increased consumer privacy, Google and Mozilla removing extended validation (EV) certificate indicators from their browsers is a step in the wrong direction. Consumer privacy suffers in the absence of strong website identity. Rather than removing the indicators, the industry should work together to improve them. Browser companies can also engage Certificate Authorities to create training schemes to help users protect themselves online, argue Tim Callan of Sectigo and Chris Bailey of Entrust Datacard.
A NEURAL NETWORK BOOSTED DOUBLE OVERDISPERSED POISSON CLAIMS RESERVING MODEL
Authors: Gabrielli Andrea 
Published: December 2019

AbstractWe present an actuarial claims reserving technique that takes into account both claim counts and claim amounts. Separate (overdispersed) Poisson models for the claim counts and the claim amounts are combined by a joint embedding into a neural network architecture. As starting point of the neural network calibration, we use exactly these two separate (overdispersed) Poisson models. Such a nested model can be interpreted as a boosting machine. It allows us for joint modeling and mutual learning of claim counts and claim amounts beyond the two individual (overdispersed) Poisson models.
Office of Information and Regulatory Affairs: Past, Present, and Future
Authors: Tozzi Jim 
Published: December 2019

AbstractThis article has three sections, each of which deals with an Executive Order. The first section, “Office of Information and Regulatory Affairs (OIRA) Past,” emphasizes the critical role that Executive Orders played in the formation of OIRA. More specifically, OIRA owes its initial existence to the establishment of a centralized regulatory review system, the Quality of Life Review, which initiated Office of Management and Budget (OMB) review of environmental regulations through the issuance of a directive from OMB. Every subsequent President expanded OMBs powers through the issuance of Executive Orders which culminated in the Iconic Executive Order 12291. The section concludes with the recommendation that a select class of Executive Orders, and OMB Directives, be designated as “Iconic” by the National Archivist in consultation with the OIRA, and then given substantial deference by incoming Administrations. The second section, “OIRA Present,” describes an Executive Order issued during the Kennedy Administration which remains in effect but was promulgated prior to the establishment of OIRA and therefore recommends that a new Executive Order be issued which gives OIRA specific authority to participate in the conduct of interagency reviews of Executive Orders. The third section, “OIRA Future,” describes an Executive Order which implements a regulatory budget (RB) and institutionalizes a mechanism for controlling the size of the administrative state. This final section of the article recommends that the aforementioned Executive Order be reviewed and modified based upon the outcome of a request for public comments, and rules with demonstrated positive net benefits should no longer be accorded an automatic entitlement for issuance as a final rule absent their inclusion in an RB.
How Political Contestation Over Judicial Nominations Polarizes Americans’ Attitudes Toward the Supreme Court
Authors: Rogowski Jon C. , Stone Andrew R. 
Published: December 2019

AbstractContemporary US Supreme Court nominations are unavoidably and inevitably political. Although observers worry that political contestation over nominations undermines support for qualified nominees and threatens the Court's legitimacy, there is little empirical evidence to support these claims. The authors argue that political contestation over judicial nominations provides cues that shape the public's impressions about nominees and the Court and polarizes public opinion across partisan lines. Data from a conjoint experiment administered in the first days of the Trump presidency support this argument. Political rhetoric attributed to President Trump and Senate Democrats substantially polarized partisans’ views of nominees and evaluations of the Court's legitimacy, with Republicans (Democrats) expressing significantly more (less) favorable attitudes. Additional analyses suggest that contestation generates divergent partisan responses by affecting views about the nominee's impartiality. These findings challenge existing perspectives that depict attitudes toward the judiciary as resistant to partisan considerations and have important implications for the Court's legitimacy in a polarized era.

Published: December 2019

AbstractBackgroundDepression even at the subclinical level is often accompanied by sleep disturbances, but little is known about the dynamics of the sleep stages in relation to depressive symptoms. We examined whether the amount, associations, and transition probabilities of various sleep stages were associated with depressive symptoms in a community sample of adolescents.MethodsThe participants (N = 172, 59% girls, mean age 16.9 years) underwent overnight polysomnography and provided data on depressive symptoms (Beck Depression Inventory II). The association between depression status and total duration of each stage type was analyzed using ANOVA and survival analyses. The associations between the number of different sleep stage types were analyzed using graphical Gaussian models, mixed graphical models, and relative importance networks. A Markov chain algorithm was used to estimate the transition probabilities between each state and these probabilities were further compared between depression status groups.ResultsThe associations between N1 and N3 were significantly stronger in both directions of the association (p-values for interactions 0.012 and 0.006) in those with more depressive symptoms. Similarly, a stronger association was observed from N1 to wake stage in those with more depressive symptoms (p-value for interaction 0.002). In those with more depressive symptoms, it was more likely to transition from N2 to N3 and from REM to N2 compared to others.ConclusionsThese findings indicate that changes in sleep architecture are not limited to clinical depression and that the transitional dynamics of sleep stages are an important marker of subclinical depression.
Designing emotional BDI agents: good practices and open questions
Authors: Sánchez-López Yanet , Cerezo Eva 
Published: December 2019

AbstractIntelligent agents built on the basis of the BDI (belief–desire–intention) architecture are known as BDI agents. Currently, due to the increasing importance given to the affective capacities, they have evolved giving way to the BDI emotional agents. These agents are generally characterized by affective states such as emotions, mood or personality but sometimes also by affective capacities such as empathy or emotional regulation. In the paper, a review of the most relevant proposals to include emotional aspects in the design of BDI agents is presented. Both BDI formalizations and BDI architecture extensions are covered. From the review, common findings and good practices modeling affect, empathy and regulatory capacities in BDI agents, are extracted. In spite of the great advance in the area several, open questions remain and are also discussed in the paper.
Varieties of political rhetorical reasoning: norm types, scorekeepers, and political projects
Authors: Sundaram Sasikumar S. 
Published: December 2019

AbstractHow does rhetoric work in the pursuit of political projects in international relations? This article analyzes how rhetoric-wielding political actors engage in reasoning to bolster their position by drawing upon norms that underwrite interactions, and audiences as scorekeepers evaluate the reasoning by making a series of inferences. I call this mechanism rhetorical reasoning. Building on the existing classification of norms in constructivist international relations (IR) and utilizing three distinct norm types – instrumental, institutional, and moral – I show the different processes through which political actors deploy rhetoric to legitimize and justify political projects and the distinct logics through which scorekeepers make inferences and evaluate the project. This article contributes to IR theories of argumentation by providing a sharp conceptualization of political rhetoric and actor–audience relationships in the game. I illustrate the mechanism of rhetorical reasoning using Brazil's UN peace enforcement operation in Haiti in 2004 to give empirical evidence for the role of institutional norm type in patterns of rhetorical reasoning and contestations in international politics. Paying attention to political rhetoric in the actor–scorekeepers' relationships in this way clarifies important issues regarding the varieties of political projects and the different role of normativity in the game.

Published: December 2019

AbstractGut bacteria from the genus Prevotella are found in high abundance in faeces of non-industrialised communities but low abundance in industrialised, Westernised communities. Prevotella copri is one of the principal Prevotella species within the human gut. As it has been associated with developmental health and disease states, we sought to (i) develop a real-time polymerase chain reaction (PCR) to rapidly determine P. copri abundance and (ii) investigate its abundance in a large group of Australian pregnant mothers.The Barwon Infant Study is a pre-birth cohort study (n = 1074). Faecal samples were collected from mothers at 36 weeks gestation. Primers with a probe specific to the V3 region of P. copri 16S rRNA gene were designed and optimised for real-time PCR. Universal 16S rRNA gene primers amplified pan-bacterial DNA in parallel. Relative abundance of P. copri was calculated using a 2-ΔCt method.Relative abundance of P. copri by PCR was observed in 165/605 (27.3%) women. The distribution was distinctly bimodal, defining women with substantial (n = 115/165, 69.7%) versus very low P. copri expression (n = 50/165, 30.3%). In addition, abundance of P. copri by PCR correlated with 16S rRNA gene MiSeq sequencing data (r2 = 0.67, P < 0.0001, n = 61).We have developed a rapid and cost-effective technique for identifying the relative abundance of P. copri using real-time PCR. The expression of P. copri was evident in only a quarter of the mothers, and either at substantial or very low levels. PCR detection of P. copri may facilitate assessment of this species in large, longitudinal studies across multiple populations and in various clinical settings.

AbstractHigh‐quality precipitation data are vital for hydrological applications and climate change research. In this study, we evaluated two satellite‐based precipitation products from Chinese Fengyun (FY) 2G (G is one of the third batch of operational geostationary satellites in the Chinese FY‐2 series) and the Global Precipitation Measurement (GPM) against the rain gauge‐based precipitation data, respectively, over the Yunnan‐Kweichow Plateau, China, at different temporal scales (e.g., monthly, daily, and hourly). And the main findings of this study were as follows: (1) FY2G Quantitative Precipitation Estimation (QPE) and Integrated Multisatellite Retrievals for GPM (IMERG) shared similar spatial precipitation patterns with those of rain gauge data, while the FY2G QPE general underestimated the precipitation (bias, −30%–0%), and IMERG obviously overestimated the precipitation (bias, 0%–60%) at monthly scale over the Yunnan‐Kweichow Plateau; (2) the FY2G QPE correlated significantly better (Correlation coefficient, CC, ~0.80) than IMERG (CC ~0.20) against rain gauge data at daily scale, meanwhile, the average daily bias value of IMERG (~30%) was around 6 times larger than that of FY2G QPE (~5%); (3) The FY2G QPE (CC ~0.7, bias ~ − 8%, root‐mean‐square error ~2.0 mm/hr, mean absolute error ~ 0.6 mm/hr) also generally outperformed the IMERG (CC ~0.1, bias ~13%, root‐mean‐square error ~3.0 mm/hr, mean absolute error ~ 1.0 mm/hr), at hourly scale; (4) The FY2G QPE significantly underestimated the precipitation in the period between 16:00 and 20:00 with the probability of detection (POD) decreased from 0.8 to 0.5, while the IMERG significantly overestimated the precipitation in the period between 4:00 and 12:00, at diurnal scale; and (5) one of the reasons resulting the significant overestimations of IMERG might due to its weak abilities in detecting the precipitation events with POD ~0.2 and false alarm ratio (FAR) ~0.7 at diurnal scale, which performed worse than those of the FY2G QPE (POD ~0.8 and FAR ~0.4). These findings would provide valuable recommendations for using these satellite‐based precipitation products in various application fields, such as hydrology, agriculture, and meteorology over the YKP, and also for improving the algorithms of GPM.
