Reciprocity: Different behavioural strategies, cognitive mechanisms and psychological processes
Authors: Schweinfurth Manon K. , Call Josep 
Published: November 2019

AbstractReciprocity is probably one of the most debated theories in evolutionary research. After more than 40 years of research, some scientists conclude that reciprocity is an almost uniquely human trait mainly because it is cognitively demanding. Others, however, conclude that reciprocity is widespread and of great importance to many species. Yet, it is unclear how these species reciprocate, given its apparent cognitive complexity. Therefore, our aim was to unravel the psychological processes underlying reciprocity. By bringing together findings from studies investigating different aspects of reciprocity, we show that reciprocity is a rich concept with different behavioural strategies and cognitive mechanisms that require very different psychological processes. We reviewed evidence from three textbook examples, i.e. the Norway rat, common vampire bat and brown capuchin monkey, and show that the species use different strategies and mechanisms to reciprocate. We continue by examining the psychological processes of reciprocity. We show that the cognitive load varies between different forms of reciprocity. Several factors can lower the memory demands of reciprocity such as distinctiveness of encounters, memory of details and network size. Furthermore, there are different information operation systems in place, which also vary in their cognitive load due to assessing the number of encounters and the quality and quantity of help. We conclude that many species possess the psychological processes to show some form of reciprocity. Hence, reciprocity might be a widespread phenomenon that varies in terms of strategies and mechanisms.
Identifying Activity-sensitive Spectral Lines: A Bayesian Variable Selection Approach
Authors: Ning Bo , Wise Alexander , Cisewski-Kehe Jessi , Dodson-Robinson Sarah , Fischer Debra 
Published: November 2019

AbstractStellar activity, such as spots and faculae, provides a noise background that may lead to false discoveries or poor mass estimates of small planets when using radial velocity (RV) techniques. Spectroscopic activity indices are often used to verify the authenticity of planet candidates. Recently, Wise et al. proposed a method to identify activity-sensitive lines through finding lines that are significantly correlated with theS-index. Their study is novel but has three limitations: their method requires the manual selection of a set of lines before conducting an analysis, dependencies between lines are ignored when calculating correlations, and using theS-index is not sufficient for identifying all activity-sensitive lines, asS-index only captures some manifestations of stellar activity. In this paper, we develop a Bayesian variable selection method that can address these limitations. Our method can automatically search for activity-sensitive lines through pixels from a set of spectra. We not only use theS-index, but also include the Hαand NaD indices, the bisector inverse slope, and the full width at half maximum. The details of the activity-sensitive lines are listed in the paper. Machine-readable tables and the code of the statistical method are available online. With stellar activity being the largest source of variability for next-generation RV spectrographs, this work is a step toward accessing the myriad information available in high-precision spectra.

Abstract
We report the discovery of an exoplanet from the analysis of the gravitational microlensing event OGLE-2015-BLG-1649 that challenges the core accretion model of planet formation and appears to support the disk instability model. The planet/host-star mass ratio is q = 7.2 × 10−3 and the projected separation normalized to the angular Einstein radius is s = 0.9. We conducted high-resolution follow-up observations using the Infrared Camera and Spectrograph (IRCS) camera on the Subaru telescope and are able to place an upper limit on the lens flux. From these measurements we are able to exclude all host stars greater than or equal in mass to a G-type dwarf. We conducted a Bayesian analysis with these new flux constraints included as priors resulting in estimates of the masses of the host star and planet. These are M

. The estimated relative lens-source proper motion, ∼7.1 mas yr−1, is fairly high and thus the lens can be better constrained if additional follow-up observations are conducted several years after the event.

Published: November 2019

Abstract
We have used the Goddard IRAM 2 Millimeter Observer (GISMO) with the 30 m IRAM telescope to carry out a 2 mm survey of the Galaxy’s central molecular zone. These observations detect thermal emission from cold interstellar medium dust, thermal free–free emission from ionized gas, and nonthermal synchrotron emission from relatively flat-spectrum sources. Archival data sets spanning 3.6 μm–90 cm are used to distinguish different emission mechanisms. After the thermal emission of dust is modeled and subtracted, the remaining 2 mm emission is dominated by free–free emission, with the exception of the brightest nonthermal filament (NTF) that runs through the middle of the bundle of filaments known as the Radio Arc. This is the shortest wavelength at which any NTF has been detected. The GISMO observations clearly trace this NTF over a length of ∼0.°2, with a mean 2 mm spectral index that is steeper than at longer wavelengths. The 2 mm–6 cm (or 20 cm) spectral index steepens from α ≈ −0.2 to −0.7 as a function distance from the Sickle H ii region, suggesting that this region is directly related to the NTF. A number of unresolved (at 21″) 2 mm sources are found nearby. One appears to be thermal dust emission from a molecular cloud that is associated with an enigmatic radio point source whose connection to the Radio Arc is still debated. The morphology and colors at shorter IR wavelengths indicate other 2 mm unresolved sources are likely to be compact H ii regions.
A Global Solution to a Slim Accretion Disk with Radiation-driven Outflows
Authors: Feng Junjie , Cao Xinwu , Gu Wei-Min , Ma Ren-Yi 
Published: November 2019

Abstract
The thickness of a slim disk is determined by the balance between the radiation force and the vertical component of the gravity of the black hole (BH). Vertical gravity is found to increase with the disk height, and it will decrease with the disk height if the disk thickness is above a critical value, which implies that gas at the disk surface may be driven into outflows by radiation force when the disk thickness surpasses the critical value. In this work, we derive a global solution to a slim disk with radiation-driven outflows. We find that the outflows are driven from the disk surface if the mass accretion rate is

even if the mass accretion rate at the outer edge of the disk is very high. This may set constraints on the massive BH growth through accretion in the early universe. Due to the presence of outflows, there is an upper limit on the radiation flux of the disk, which leads to saturation of the continuum spectra of the disk with outflows at the high-energy band. This may be tested by the observations of quasars or/and BH X-ray binaries.
Multiscale Time- and Frequency-domain Likelihood Analysis with Photon Weights
Authors: Kerr M. 
Published: November 2019

Abstract
We present an unbinned likelihood analysis formalism employing photon weights—the probabilities that events are associated with a particular source. This approach is applicable to any photon-resolving instrument and thus well suited to high-energy observations; we focus here on GeV γ-ray data from the Fermi Large Area Telescope. Weights connect individual photons to the outputs of a detailed, expensive likelihood analysis of a much larger data set. The weighted events can be aggregated into arbitrary time spans ranging from microseconds to years. Such retrospective grouping permits time- and frequency-domain analysis over a wide range of scales and enables characterization of disparate phenomena like blazar flares, γ-ray bursts, pulsar pulses, novae, γ-ray binaries, and other variable sources. To demonstrate the formalism, we incorporate photon weights into the Bayesian blocks algorithm and perform a hierarchical timescale analysis of 3C 279 activity. We analyze pulsar pulse profiles and estimate the unpulsed emission level and the optimal division of the data into on- and off-pulse intervals. We extend the formalism to Fourier analysis and derive estimators for power spectra, used to search for and characterize periodic sources. We show how the fast Fourier transform can be used to probe orbital periods as short as a minute, and we discuss the mitigation of spurious signals. Our final example combines time- and frequency- domain analysis to jointly characterize the flares and orbital modulation of Cygnus X-3, yielding the strongest detection of the orbital signal (>13σ) to date. Finally, we discuss extensions of the work to other GeV sources and to X-ray and TeV observations.
Solar Flare Prediction with the Hybrid Deep Convolutional Neural Network
Authors: Zheng Yanfang , Li Xuebao , Wang Xinshuo 
Published: November 2019

Abstract
We propose a hybrid Convolutional Neural Network (CNN) model (Model 2) and modify a popular CNN model (Model 1) to predict multiclass solar flare occurrence within 24 hr. We collect samples of solar active regions provided by the Space-weather Helioseismic and Magnetic Imager Active Region Patches data from 2010 May to 2018 September. These samples are categorized into four classes (No-flare, C, M, and X), containing 10 separate data sets. Then after training, validating, and testing our models, we compare the results with previous studies in forecast verification metrics with an emphasis on the true skill statistic (TSS). The main results are summarized as follows. (1) This is the first time that the CNN models are used to make multiclass predictions of solar flare. (2) Model 2 has better values of all statistical scores than Model 1 in every class. (3) Model 2 achieves relatively high average scores of TSS = 0.768 for No-flare class, 0.538 for C class, 0.534 for M class, and 0.552 for X class, which are the best results from the existing literatures. (4) Model 2 also can be used to make binary class flare predictions for ≥M-class major flares, and the performance yields a TSS with 0.749 ± 0.079. (5) Model 2 obtains fairly good scores in other metrics for both multiclass flare predictions and ≥M-class major flare predictions. We surmise that some crucial features extracted automatically by our models may have not been excavated before and could provide important clues for studying the mechanism of flare.

Objective.Systemic lupus erythematosus (SLE) is a multisystem chronic inflammatory autoimmune disease with high prevalence of several risk factors for atrial fibrillation/flutter (AF). However, the incidence and risk of AF in SLE have not been well quantified.Methods.We used the United States Medicaid Analytic eXtract from 2007 to 2010 to identify beneficiaries aged 18–65 years, with prevalent SLE, each matched by age and sex to 4 non-SLE general Medicaid recipients. We estimated the incidence rates (IR) per 1000 person-years (PY) for AF hospitalizations and used multivariable Cox regression to estimate the HR for AF hospitalization.Results.We identified 46,876 US Medicaid recipients with SLE, and 187,504 age- and sex-matched non-SLE controls (93% female; mean age 41.5 ± 12.2 yrs). Known AF risk factors such as hypertension (HTN), cardiovascular disease (CVD), and kidney disease were more prevalent in patients with SLE. During a mean followup of 1.9 ± 1.1 years for SLE, and 1.8 ± 1.1 years for controls, the IR per 1000 PY for AF was 1.4 (95% CI 1.1–1.6) among patients with SLE and 0.7 (95% CI 0.6–0.8) among non-SLE controls. In age- and sex-matched and race-adjusted Cox models, the HR for AF was 1.79 (95% CI 1.43–2.24); after adjustment for baseline HTN and CVD, the adjusted HR was reduced to 1.17 (95% CI 0.92–1.48).Conclusion.SLE was associated with a doubled rate of hospitalization for AF compared to age- and sex-matched general Medicaid patients. In a race-adjusted model, the risk was 80% higher. However, the AF risk factors HTN and CVD were more prevalent among patients with SLE and accounted for the excess risk.

Published: November 2019

ObjectiveRemission or low disease activity should be the treatment target of psoriatic arthritis (PsA). However, residual disease activity (RDA) in some domains could persist. The aim of this study was to assess RDA and its associated factors in a group of patients with PsA.MethodsPatients with PsA were enrolled if they satisfied ClASsification for Psoriatic ARthritis (CASPAR) criteria with > 6 months’ followup and achieved a status of low disease activity (LDA), minimal disease activity (MDA), or remission [Disease Activity Index for PsA (DAPSA) remission or very low disease activity (VLDA)]. RDA was assessed by the percentage of patients who had, although in LDA or remission, tender and/or swollen joints > 1, Leeds Enthesitis Index > 1, Health Assessment Questionnaire > 0.5, Psoriasis Area Severity Index (PASI) > 1, patient’s global assessment > 20, physician visual analog scale (VAS) > 20, and VAS pain > 15. Associated factors of RDA were also assessed.ResultsOf 113 enrolled patients, 78 (69%) were in MDA. Moreover, DAPSA remission was observed in 46 (40.7%) while VLDA only in 32 (28.3%) of patients with PsA. VLDA seems to be the most stringent criterion, with a minimal RDA only in the VAS physician in 1 patient (3.1%) and none in the different domains, while patients in MDA had RDA in tender joints (14.1%), VAS pain (29.4%) and PASI > 1 or body surface area (BSA) > 3% (17.9%). Of note, although patients in DAPSA remission show a very low rate of RDA in almost all domains, 12 (26%) of them show a PASI > 1 or BSA > 3%. Finally, LDA shows RDA in higher percentages, mainly in patient-reported outcomes, tender joints, and skin domain.ConclusionRDA can be recognized in patients with PsA. VLDA seems to be the most stringent composite index to identify patients in the absence of RDA.
