Crowdsourcing Truth Inference via Reliability-Driven Multi-View Graph Embedding

Crowdsourcing truth inference aims to assign a correct answer to each task from candidate answers that are provided by crowdsourced workers. A common approach is to generate workers’ reliabilities to represent the quality of answers. Although crowdsourced triples can be converted into various crowdsourced relationships, the available related methods are not effective in capturing these relationships to alleviate the harm to inference that is caused by conflicting answers. In this research, we propose a Reliability-driven Multi-view Graph Embedding framework for Truth inference (TiReMGE), which explores multiple crowdsourced relationships by organically integrating worker reliabilities into a graph space that is constructed from crowdsourced triples. Specifically, to create an interactive environment, we propose a reliability-driven initialization criterion for initializing vectors of tasks and workers as interactive carriers of reliabilities. From the perspective of multiple crowdsourced relationships, a multi-view graph embedding framework is proposed for reliability information interaction on a task-worker graph, which encodes latent crowdsourced relationships into vectors of workers and tasks for reliability update and truth inference. A heritable reliability updating method based on the Lagrange multiplier method is proposed to obtain reliabilities that match the quality of workers for interaction by a novel constraint law. Our ultimate goal is to minimize the Euclidean distance between the encoded task vector and the answer that is provided by a worker with high reliability. Extensive experimental results on nine real-world datasets demonstrate that TiReMGE significantly outperforms the nine state-of-the-art baselines.
A New Species of Baleen Whale (Isanacetus-Group) from the Early Miocene, Japan

Abstract. The Isanacetus-group is one of the most enigmatic groups of cetaceans. Although their phylogeny is still controversial, many previous studies suggested that they are a paraphyletic group of baleen whales, including an ancestor of Balaenopteridae and Eschrichtiidae. A new fossil from an Isanacetus-group baleen whale has been recovered from the Minamishirado Formation (latest early Miocene, Burdigalian), Iwaki, Fukushima Prefecture, Japan. The specimen consists of a cranium, mandible, and postcranial elements, including cervical, thoracic, and lumbar vertebrae, scapula, ulna, and ribs. We describe and diagnose the specimen as a new genus and species, Jobancetus pacificus. A unique combination of morphological characters characterized the specimen, e.g. frontals forming a triangular elevated plateau at the vertex, sharp, and well-developed transverse crest on the supraorbital process of frontal, sagittal crest formed by frontals and parietals, and large squamosal fossa, which is posteriorly extended well beyond the level of the posterior surface of the occipital condyle. Phylogenetic analysis under equal weighting suggests that J. pacificus is a stem group of Pligogulae, whereas the phylogenetic analyses under implied weightings suggest that J. pacificus is a stem group of Balaenopteridae + Eschrichtiidae. The discovery of J. pacificus expands our knowledge of the enigmatic Isanacetus-group.
Susceptibility Status to Temephos in Larval Aedes aegypti and Aedes albopictus (Diptera: Culicidae) Populations from Quintana Roo, Southeastern Mexico

Summary In Mexico, the larvicide temephos (an organophosphate) has been used widely for vector control for a number of yr. Repeated exposure to this larvicide has caused resistance in Aedes container-inhabiting larvae. In this study, the susceptibility status to temephos was evaluated in Ae. albopictus and Ae. aegypti larvae from 4 locales within Quintana Roo, Mexico. Aedes aegypti exhibited low-intensity phenotypic resistance in Cancún, Playa del Carmen, José María Morelos, and Chetumal. Aedes albopictus was found to be susceptible to temephos in Chetumal and Playa del Carmen, but low-intensity phenotypic resistance (tolerance) was observed in Cancún and José María Morelos. The changes in susceptibility status to temephos in both species could be caused by different degrees of exposure to this larvicide. However, more in-depth studies are required to confirm this. Sumario En México, el larvicida temefos (organofosforado) se ha utilizado ampliamente para el control de vectores durante varios años. La exposición prolongada a este compuesto ha provocado resistencia en las larvas del género Aedes. En este estudio, el estado de la susceptibilidad a temefos fue evaluado en larvas de Ae. albopictus y Ae. aegypti de cuatro comunidades de Quintana Roo, México. Aedes aegypti mostró una resistencia fenotípica de baja intensidad en Cancún, Playa del Carmen, José María Morelos, y Chetumal. Por otro lado, las poblaciones de Ae. albopictus de Chetumal y Playa del Carmen fueron susceptibles al larvicida, sin embargo, se observó resistencia fenotípica de baja intensidad en Cancún y José María Morelos. Los cambios en el estado de susceptibilidad a temefos de ambas especies puede deberse a los diferentes niveles de exposición al larvicida, sin embargo, se requiere de estudios más profundos para confirmarlo.
A CONCISE AXIOMATIZATION OF RM

A new axiomatization for the implicational fragment of Dunn’s system RM is given. The new axiomatization is considerably more concise than the axiomatization that was previously known. Speciflcally, we show that the two axioms CCpCpqCpq and CCCCCpqqprCCCCCqppqrr may be replaced with either CCCpCCCqprqrr or CCCCCpqrCqprr. Because the implicational fragment of RM coincides with the implicational fragment of Sobocinski’s system S, the new axiomatization provides a concise basis for that system as well. Let R be the system of relevant implication, and let R! be its implicational fragment. R! is given by the following independent axiom-schema, with the rules modus ponens and substitution [6], p. 88:
Telemonitoring of Elderly with Hypertension and Type 2 Diabetes at the Primary Care Level: Protocol for a Multicentric Randomized Controlled Pilot Study

Abstract Introduction Arterial hypertension (AH) and type 2 diabetes (T2D) represent a significant burden for the public health system, with an exceptionally high prevalence in patients aged ≥65 years. This study aims to test the acceptability, clinical effectiveness, and cost-effectiveness of telemonitoring in elderly patients with AH and T2D at the primary care level. Methods A m ulti-centre, prospective, randomized, controlled t rial w ill be conducted. Patients a ged ≥ 65 y ears with AH and T2D will be randomized in a 1:1 proportion to a mHealth intervention or standard care group. Patients in the intervention group will measure their blood pressure (BP) twice weekly and blood glucose (BG) once monthly. The readings will be synchronously transmitted via a mobile application to the telemonitoring platform, where they will be reviewed by a general practitioner who will indicate changes in measurement regimen or carry out a teleconsultation. The primary endpoint will be a change in systolic BP (SBP) and glycated haemoglobin (HbA1c) relative to standard care up to 12 months after inclusion. Secondary endpoints will be a change in other observed clinical variables, quality-of-life indexes, and costs. Expected results Telemonitoring will be an acceptable method of care associated with significant reductions in SBP and HbA1c levels and an increase in quality-of-life indexes in the intervention group. However, the cost-effectiveness threshold (incremental cost-effectiveness ratio below €25,000/quality-adjusted life year) might not be reached. Conclusion This study will provide new evidence for scaling up telemonitoring network at the primary care level and modifying telemonitoring protocols to achieve the best clinical and cost-effective outcomes.
Modified-operator method for the calculation of band diagrams of crystalline materials

In solid state physics, electronic properties of crystalline materials are often inferred from the spectrum of periodic Schr\"odinger operators. As a consequence of Bloch's theorem, the numerical computation of electronic quantities of interest involves computing derivatives or integrals over the Brillouin zone of so-called energy bands, which are piecewise smooth, Lipschitz continuous periodic functions obtained by solving a parametrized elliptic eigenvalue problem on a Hilbert space of periodic functions. Classical discretization strategies for resolving these eigenvalue problems produce approximate energy bands that are either non-periodic or discontinuous, both of which cause difficulty when computing numerical derivatives or employing numerical quadrature. In this article, we study an alternative discretization strategy based on an ad hoc operator modification approach. While specific instances of this approach have been proposed in the physics literature, we introduce here a systematic formulation of this operator modification approach. We derive a priori error estimates for the resulting energy bands and we show that these bands are periodic and can be made arbitrarily smooth (away from band crossings) by adjusting suitable parameters in the operator modification approach. Numerical experiments involving a toy model in 1D, graphene in 2D, and silicon in 3D validate our theoretical results and showcase the efficiency of the operator modification approach.
The ESO UVES Advanced Data Products quasar sample - V. Identifying the galaxy counterpart to the sub-damped Lyα system towards Q 2239-2949

Gas flows in and out of galaxies are one of the key unknowns in todays' galaxy evolution studies. Because gas flows carry mass, energy and metals, they are believed to be closely connected to the star formation history of galaxies. Most of these processes take place in the circum-galactic medium (CGM) which remains challenging to observe in emission. A powerful tool to study the CGM gas is offered by combining observations of the gas traced by absorption lines in quasar spectra with detection of the stellar component of the same absorbing-galaxy. To this end, we have targeted the zabs=1.825 sub-Damped Ly-alpha absorber (sub-DLA) towards the zem=2.102 quasar 2dF J 223941.8-294955 (hereafter Q2239-2949) with the ESO VLT/X-Shooter spectrograph. Our aim is to investigate the relation between its properties in emission and in absorption. The derived metallicity of the sub-DLA with log N(HI) = 19.84+/-0.14 cm-2 is [M/H] >-0.75. Using the Voigt profile optical depth method, we measure Delta_v90(FeII)=64 kms-1. The sub-DLA galaxy counterpart is located at an impact parameter of 2. "4+/-0. "2 (20.8+/-1.7 kpc at z = 1.825). We have detected Ly-alpha and marginal [OII] emissions. The mean measured flux of the Ly-alpha line is F(Ly-alpha) ~ 5.7x10^-18 erg s-1 cm-2 A-1, corresponding to a dust uncorrected SFR of ~ 0.13 M(solar) yr-1.
Soil‐dwelling Bacillus spp. affects aphid infestation of calabrese and natural enemy responses in a context‐specific manner

Plant growth‐promoting rhizobacteria in the genus Bacillus have been shown to reduce growth and increase parasitism of some aphids, but the generality of these interactions is unknown. All previous studies have taken place in temperate conditions. We studied the effects of seed application of three Bacillus species, singly and in mixture, on three aphid pests and their natural enemies, on field‐grown calabrese (green sprouting broccoli) in the subtropical climate of South West India. All three bacteria reduced populations of Brevicoryne brassicae and Myzus persicae, but had no effect on numbers of Lipaphis erysimi. Chewing insects (flea beetles and diamondback moth larvae) were also unaffected by the treatments. However, parasitism rates of aphids were higher on plants treated with the bacteria. We conclude that Bacillus spp. shape above ground interactions in a context‐specific manner, directly via altered field infestations of some pests and indirectly via natural enemy responses.
Inversion of stellar fundamental parameters from ESPaDOnS and Narval high-resolution spectra

The general context of this study is the inversion of stellar fundamental parameters from high-resolution Echelle spectra. We aim at developing a fast and reliable tool for the post-processing of spectra produced by ESPaDOnS and Narval spectropolarimeters. Our inversion tool relies on principal component analysis. It allows reducing dimensionality and defining a specific metric for the search of nearest neighbours between an observed spectrum and a set of observed spectra taken from the Elodie stellar library. Effective temperature, surface gravity, total metallicity, and projected rotational velocity are derived. Various tests presented in this study that were based solely on information coming from a spectral band centred on the Mg  b-triplet and had spectra from FGK stars are very promising.
Cosmography and cosmic acceleration

We investigate the prospects for determining the accelerating history of the Universe from upcoming measurements of the expansion rate H(z). In our analyses, we use Monte Carlo simulations based on w cold dark matter models to generate samples with different characteristics and calculate the evolution of the deceleration parameter q(z). We show that a cosmographic (and, therefore, model-independent) evidence for cosmic acceleration [q(z < zt) < 0, where zt is the transition redshift] will be possible only with an accuracy in H(z) data expected in some planned surveys. A brief discussion about the prospects for reconstructing the dark energy equation of state from the parameters H(z) and q(z) is also included.
The orientation dependence of quasar single-epoch black hole mass scaling relationships

Black hole masses are estimated for radio-loud quasars using several self-consistent scaling relationships based on emission-line widths and continuum luminosities. The emission lines used, Hβ, Mgii λ2798, and Civ λ1549, have different dependencies on orientation as estimated by radio core dominance. We compare differences in the log of black hole masses estimated from different emission lines and show that they depend on radio core dominance in the sense that core-dominated, jet-on objects have systematically smaller Hβ and Mgii determined masses compared to those from Civ, while lobe-dominated edge-on objects have systematically larger Hβ and Mgii determined masses compared to those from Civ. The effect is consistent with the Hβ line width, and to a lesser extent that of Mgii, being dependent upon orientation in the sense of a axisymmetric velocity field plus a projection effect. The size of the effect is nearly an order of magnitude in black hole mass going from one extreme orientation to the other. We find that radio spectral index is a good proxy for radio core dominance and repeating this analysis with radio spectral index yields similar results. Accounting for orientation could in principle significantly reduce the scatter in black hole mass scaling relationships, and we quantify and offer a correction for this effect cast in terms of radio core dominance and radio spectral index.
Properties of the Variation of the Infrared Emission of OH/IR Stars

In order to study properties of the pulsation in the infrared emission for long period variables, we collect and analyze the infrared observational data at L band for 12 OR/IR. The observation data cover about three decades including recent data from the ISO and Spitzer. We use the Marquardt-Levenberg algorithm to determine the pulsation period and amplitude for each star and compare them with results of previous investigations at infrared and radio bands. We obtain the relationship between the pulsation periods and the amplitudes at L band. Contrary to the results at K band, there is no difference of the trends in the short and long period regions of the period-luminosity relation at L band. This may be due to the molecular absorption effect at K band. The correlations among the L band parameters, IRAS [12-25] colors, and K band parameters may be explained as results of the dust shell parameters affected by the stellar pulsation. The large scatter of the correlation could be due to the existence of a distribution of central stars with various masses and pulsation modes.
Edaphic specialization onto bare, rocky outcrops as a factor in the evolution of desert angiosperms

Understanding the processes that enable organisms to shift into more arid environments as they emerge is critical for gauging resilience to climate change, yet these forces remain poorly known. In a comprehensive clade-based study, we investigate recent shifts into North American deserts in the rock daisies (Perityleae), a diverse tribe of desert sunflowers (Compositae). We sample Perityleae across two separate contact zones between tropical deciduous forest and desert biomes in western North America and infer a time-calibrated phylogeny based on target capture sequence data. We reconstruct biome shifts using Bayesian inference with paleobiome-informed models and find evidence for seven independent shifts into desert habitats since the onset of aridification in the late Miocene epoch. The earliest shift occurred out of tropical deciduous forests and led to an extensive radiation throughout North American deserts that accounts for the majority of extant desert Perityleae. Reconstructions of life history and micro-habitat in Perityleae reveal a correlation between a suffrutescent perennial life history and edaphic endemism onto rocky outcrops, an ecological specialization that evolved prior to establishment and diversification in deserts. That the insular radiation of desert rock daisies stemmed from ancestors pre-adapted for dry conditions as edaphic endemics in otherwise densely vegetated tropical deciduous forests in northwest Mexico underscores the crucial role of exaptation and dispersal for shifts into arid environments. Significance Statement The environmentally stressful conditions found in desert regions have often been implicated as the main factor in the evolution of drought tolerance in desert plants. Yet many iconic desert plant lineages evolved prior to the recent emergence of widespread arid climates, suggesting an important role for pre-adaptation (exaptation). In the desert rock daisies (Perityleae), we provide empirical support for this view by showing that life history evolution associated with their ecological specialization onto rock outcrops was a precursor to their establishment and extensive diversification in North American deserts. We caution against assuming the presence of ancient dry biomes based on time-calibrated phylogenies and we emphasize the fundamental roles that exaptation and dispersal play during community assembly in novel environments.
Perplexity about periodicity repeats perpetually: A response to Brookshire

Brookshire (2022) claims that previous analyses of periodicity in detection performance after a reset event suffer from extreme false-positive rates. Here we show that this conclusion is based on an incorrect implemention of a null-hypothesis of aperiodicity, and that a correct implementation confirms low false-positive rates. Furthermore, we clarify that the previously used method of shuffling-in-time, and thereby shuffling-in-phase, cleanly implements the null hypothesis of no temporal structure after the reset, and thereby of no phase locking to the reset. Moving from a corresponding phase-locking spectrum to an inference on the periodicity of the underlying process can be accomplished by parameterizing the spectrum. This can separate periodic from non-periodic components, and quantify the strength of periodicity.
A national professional development program fills mentoring gaps for postdoctoral researchers

The Postdoc Academy: Succeeding as a Postdoc was designed to build postdocs’ skills in career transition, career planning, collaborative research, resilience, and selfreflection. This study examined self-reported changes in five skills as learners progressed through the course. Data were collected from participants who responded to both pre- and post-surveys and engaged with the course learning activities. Results from repeated measures multivariate analysis of variance revealed that all of the selfreported perceptions of skills improved significantly upon completion of the course. Hierarchical regressions revealed that underrepresented minority learners had greater gains in their development of skills in career planning, resilience, and self-reflection. Qualitative analysis of learners’ responses to learning activities found that postdocs perceived networking and mentor support as contributing factors to their skill advancement while tensions among multiple obligations and concerns of uncertainties were significant challenges to applying those skills.
The assembly of wild natural isolates define neuronal integrity and life history traits of co-inhabiting C. elegans

Bacterivore nematodes are the most abundant animals in the biosphere, largely contributing to global biogeochemistry. The effect of environmental microbes as source of associated microbiota and natural diet on their life history traits of nematodes is likely to impact the general health of the biosphere. Caenorhabditis elegans is a unique model to study the behavioral and physiological outputs of different available microbial diets. Nonetheless, most studies are on monoaxenic cultures of laboratory bacteria while the effect of natural microbiota isolates has only recently started to be reported. Here, we quantified physiological, phenotypical and behavioral traits of worms feeding on two bacteria that co-isolated with wild nematodes and tested how combinations of these isolates with other bacteria affected the traits measured. These bacteria were identified as a putative novel species of Stenotrophomonas denominated Stenotrophomonas sp. Iso1 and a strain of Bacillus pumilus designated Iso2. The isolates induced distinctive behaviors and development patterns that changed in mixes of the two bacteria and/or the pathogen Salmonella enterica. Focusing on the degeneration rate of the touch circuit of C. elegans we show that B. pumilus alone is protective while the mix with Stenotrophomonas sp. is degenerative. The analysis of the metabolite content of each isolate and their combination identified NAD+ as potentially neuroprotective. In vivo supplementation shows that NAD+ restores neuroprotection to the mixes and also to individual non-protective bacteria. The results highlight the need to study the physiological effects of bacteria resembling native diets in a multicomponent scenario rather than using single isolates. Importance The behavioral decisions of animals depend on their microbiota. In nature it is unknown how this interaction affects the health of the biosphere. To study how the nematode-bacteria relationship impacts the life history traits of these animals, we isolated bacteria found in association with wild nematodes and tested their influence as single species and consortia, in the life history traits of the model C. elegans. We identify metabolites from wild bacteria that change these traits. The bacteria isolated were identified a Stenotrophomonas sp and a B. pumilus. We find that all traits depend on the biota composition. For example, B. pumilus is neuroprotective to degenerating neurons of the touch circuit of C. elegans needed to sense and escape from predators in the wild. The co-culture with Stenotrophomonas sp. eliminates the protection. We identified NAD+ as the metabolite lost in the mix, and show that NAD+ by itself is neuroprotective.
