THE GALEX TIME DOMAIN SURVEY. I. SELECTION AND CLASSIFICATION OF OVER A THOUSAND ULTRAVIOLET VARIABLE SOURCES

We present the selection and classification of over a thousand ultraviolet (UV) variable sources discovered in ∼40 deg2 of GALEX Time Domain Survey (TDS) NUV images observed with a cadence of 2 days and a baseline of observations of ∼3 years. The GALEX TDS fields were designed to be in spatial and temporal coordination with the Pan-STARRS1 Medium Deep Survey, which provides deep optical imaging and simultaneous optical transient detections via image differencing. We characterize the GALEX photometric errors empirically as a function of mean magnitude, and select sources that vary at the 5σ level in at least one epoch. We measure the statistical properties of the UV variability, including the structure function on timescales of days and years. We report classifications for the GALEX TDS sample using a combination of optical host colors and morphology, UV light curve characteristics, and matches to archival X-ray, and spectroscopy catalogs. We classify 62% of the sources as active galaxies (358 quasars and 305 active galactic nuclei), and 10% as variable stars (including 37 RR Lyrae, 53 M dwarf flare stars, and 2 cataclysmic variables). We detect a large-amplitude tail in the UV variability distribution for M-dwarf flare stars and RR Lyrae, reaching up to |Δm| = 4.6 mag and 2.9 mag, respectively. The mean amplitude of the structure function for quasars on year timescales is five times larger than observed at optical wavelengths. The remaining unclassified sources include UV-bright extragalactic transients, two of which have been spectroscopically confirmed to be a young core-collapse supernova and a flare from the tidal disruption of a star by dormant supermassive black hole. We calculate a surface density for variable sources in the UV with NUV < 23 mag and |Δm| > 0.2 mag of ∼8.0, 7.7, and 1.8 deg−2 for quasars, active galactic nuclei, and RR Lyrae stars, respectively. We also calculate a surface density rate in the UV for transient sources, using the effective survey time at the cadence appropriate to each class, of ∼15 and 52 deg−2 yr−1 for M dwarfs and extragalactic transients, respectively.
From Parents to Mentors: Parent-Child Interaction in Co-Making Activities

Making activities for children often take place at informal learning environments. In this context parents may join their children for co-making activity. It has been shown that this type of activity can be facilitated by educators that serve as mentors. In this paper we aim to explore parent-child interaction in the context of a co-making activity at home. Towards that end, we developed a dedicated kit that couples Automata-building with paper circuits. We also designed five activity cards as scaffolding for parents, to raise their awareness to mentoring principles. We present our design process, evaluation, and findings from eight parent-child co-making activities. Our qualitative analysis indicates the challenges and opportunities for parents as mentors in a co-making activity. We propose a two-dimensional scale that can help designers and maker-space practitioners better understand the different parental roles during a parent-child co-making activities, and the need for better tools and support materials for parents in that context.
High-Throughput Screening of Lead-Free Perovskite-like Materials for Optoelectronic Applications

We use high-throughput density functional theory calculations to screen lead-free perovskite-like materials with compositions A2BB′X6, ABX4, and A3B2X9 for optoelectronic performance. We screen monovalent A and B′ cations from Na, K, Rb, Cs Cu, and Ag, trivalent B cations from Ga, In, and Sb, and monovalent anions from Cl, Br, and I. Our screening procedure is based on formation energy and hybrid HSE06 functional predicted bandgaps. We screened more than 480 compounds and found 10 compounds that have bandgaps in the 1.5–2.5 eV range. Of these 10 compounds, seven are new, not having been reported before. We further characterize effective masses, density of states, and absorption coefficients of these selected compounds for their suitability in optoelectronic applications. All 10 of these selected compounds are lead-free and are solution processable. These compounds pave a path forward for lead-free photovoltaics and light emission devices.
Fear of dental treatment--an underrecognized symptom in people with impaired mental health.

BACKGROUND In industrialized countries, about 5% to 15% of all adults have a pathologically severe fear of dental treatment, and some 3% avoid going to the dentist altogether. The affected persons may, in turn, suffer from severe dental diseases and their psychosocial effects. Many people with dental phobia have other mental disorders as well. These facts motivated us to study the prevalence of fear of dental treatment in a group of patients being treated by our psychosomatic service. METHOD 212 patients of our psychosomatic service and 95 healthy controls were studied with the Hierarchical Anxiety Questionnaire (HAQ) to determine the intensity of their fear of dental treatment. Mental disorders were diagnosed with structured clinical interviews according to DSM-IV. RESULTS Nearly one patient in three (30.5%, n = 64) suffered from pathologically severe fear of dental treatment; 24 of them (38.5%) had avoided visiting a dentist for longer than one year. Only 4 (4.2%) of the healthy controls were greatly afraid of dental treatment. Certain types of mental disorder were especially highly associated with fear of dental treatment: in particular, anxiety disorders (relative risk [RR] 7.44, 95% confidence interval [CI] 2.68-20.70) and depressive disorders (RR 4.92, 95% CI 1.73-14.05). Patients with post-traumatic stress disorder were affected most commonly: 34 (42%) of these patients were greatly afraid of dental treatment (RR 9.97, 95% CI 3.69-26.90). 75 of the 134 study participants who were afraid of dental treatment (56%) had cancelled a dental appointment, or failed to appear for a scheduled appointment, because of their fears. CONCLUSION Fear of dental treatment commonly accompanies certain types of mental disorder. Patients at high risk should be asked about such fears so that the problem can be recognized early and appropriately treated.
Analysis of patterns of three-phase bone scintigraphy for patients with complex regional pain syndrome diagnosed using the proposed research criteria (the 'Budapest Criteria').

BACKGROUND Three-phase bone scintigraphy (TPBS) is an established objective diagnostic method for complex regional pain syndrome (CRPS), but its validity remains controversial. The aims of this study were: (i) to re-evaluate the diagnostic performance of TPBS, and (ii) to suggest new TPBS criteria based on the proposed research criteria for CPRS in Budapest (the 2003 Budapest research criteria). METHODS The medical records of 228 consecutive patients, evaluated using the Budapest research criteria, were retrospectively analysed. Of these, 116 patients were included in the present study, and 69 of 116 were diagnosed to have CRPS based on these criteria. The diagnostic performance of TPBS was assessed by determining its sensitivity, specificity, and positive and negative likelihood ratios, and new criteria for TPBS were identified by pattern analysis using the Budapest research criteria. RESULTS The sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio of TPBS for the diagnosis of CRPS according to the Budapest research criteria were 40.0, 76.5, 1.73, and 0.78, respectively. Furthermore, D-D-D, D-D-S, and D-D-I patterns [i.e. according to decreased (D), symmetrical (S), or increased (I) tracer uptake during Phases I, II, and III] of TPBS were found to be positively predictive for CRPS. CONCLUSIONS The diagnostic value of a positive TPBS for CRPS is low from the view point of the Budapest research criteria. Our findings suggest that a diagnosis of CRPS using the Budapest research criteria should be considered when decreased patterns of TPBS are observed during Phases I and II.
Diapause status of females affects attraction of male pear psylla, Cacopsylla pyricola, to volatiles from female‐infested pear shoots

A companion study showed that male pear psylla, Cacopsylla pyricola (Förster) (Homoptera: Psyllidae) were attracted to volatiles from pear shoots infested with post‐diapause females. The present study compared the behavioral response of males to diapause and post‐diapause females. Assays were done using a Y‐tube olfactometer. We collected male and female winterform psylla from pear orchards at regular intervals between late October (early diapause) and late February (post‐diapause). Female‐infested shoots were not attractive to males until the February samples, coinciding with ovarian maturation and onset of mating in the field. A second set of assays was done in which we manipulated diapause status in the laboratory either by exposing psylla to a long‐day photoperiod or by treating insects with an insect growth regulator, fenoxycarb. In the photoperiod experiments, both short‐day and long‐day males preferentially selected long‐day (post‐diapause) females over short‐day (diapause) females. Fenoxycarb‐treated males preferred fenoxycarb‐treated (post‐diapause) females over untreated (diapause) females; untreated males showed no preferences. Results support observations made elsewhere that male winterform pear psylla perceive and are attracted to volatile odors associated with pear shoots infested with post‐diapause females.
Total Lipids, Lipid Classes, and Fatty Acids of Newly Settled Red King Crab (Paralithodes camtschaticus): Comparison of Hatchery-Cultured and Wild Crabs

ABSTRACT Little is known about the nutrition or lipid metabolism of cold-water crabs, particularly in the North Pacific. We undertook a 2-part study to understand more completely the energetics and nutritional requirements of juvenile red king crab (RKC; Paralithodes camtschaticus). First, we investigated changes in proximate composition, total lipids (TLs), lipid classes, and fatty acids (FAs) throughout a molt cycle (C4–C5). Trends in lipid parameters were described by a 3-part piecewise linear regression with 3 distinct stages: (1) a postmolt phase (∼0–7 days), (2) an intramolt stage (∼7–24 days), and (3) a premolt stage (∼24–33 days). Significant intramolt differences in TLs indicated that caution should be taken when comparing crabs of unknown molt stage in future aquaculture and ecological experiments. However, little variability was found in the proportional FA composition of crabs, indicating that the intramolt stage has little effect on the interpretation of FA biomarkers. During a second investigation, we examined differences in lipid classes and FAs from cultured and wild RKC. We found significantly higher proportions of the essential fatty acids (EFAs) 20:5n-3 (EPA) and 20:4n-6 (AA) in wild crabs compared with cultured animals at the same stage. Furthermore, higher proportions of bacterial markers and lower proportions of Zooplankton FA markers were found in wild than in hatchery-reared crabs. Here, we provide the first baseline data for future dietary studies on juvenile cold-water crabs. We suggest that an initial EFA ratio for DHA:EPA:AA of 5:8:1 could be used as a starting point for controlled dietary studies on the effect of EFAs on juvenile growth, molt success, and survival.
Investigation into “Normal” Background DNA on Adult Necks: Implications for DNA Profiling of Manual Strangulation Victims

Abstract: Others have investigated the role that DNA profiling could play as a method for identifying the perpetrator of manual strangulation. These studies have demonstrated that it is possible to collect offender DNA from the skin surface of a victim following physical contact. It is not known whether nonself biological material is normally present on the skin surface due to adventitious transfer occurring during innocent everyday interactions. To test the hypothesis that detectable amounts of nonself DNA are normally present on the skin surface of healthy adult individuals due to the adventitious transfer of DNA occurring during normal day‐to‐day social interactions, we designed an experiment in three phases. Phase 1 was used to deduce which DNA collection, extraction, and amplification methods were suited to investigating this question. During phase 2, the neck surface of 24 healthy adult volunteers was swabbed. DNA was extracted using the QIAamp DNA mini kit and amplified using the SGM Plus PCR amplification kit, using 28 PCR cycles. The work carried out during phase 3 involved a simulated assault to investigate primary and secondary transfer of DNA during physical contact. It was found that 23% of neck areas swabbed during phase 2 of this investigation showed nondonor alleles in the resulting DNA profile, with 5% of areas showing six or more nondonor alleles. The results of phase 3 showed that primary, secondary, and zero transfer of victim and/or offender DNA could be observed after physical contact and that alleles from an unknown source could still be detected in this more controlled experiment. The data presented in this paper demonstrate that DNA profiles generated after swabbing the skin surface of healthy adults can include components of an unknown source, present due to adventitious transfer. These components, if present in large quantities, have the potential to interfere with DNA profile interpretation of swabs taken for the investigation of physical assault by DNA profiling.
An Energy Efficient Dynamically Reconfigurable QR Decomposition for Wireless MIMO Communication

In this paper, we present a dynamically reconfigurable QR decomposition architecture for agile multi-input multi-output (MIMO) communication system. The proposed architecture is meant to address preprocessing bottleneck of MIMO decoding associated with the integration of multiple high speed wireless standards onto a single chip. The architecture is based on fixed point arithmetic, and uses Modified Gram-Schmidt (MGS) algorithm. It supports multiple antenna configurations of 2 × 2, 4 × 4 and 8 × 8, as specified in various wireless standards such as IEEE802.11n/ac, IEEE802.16e/m, 3GPP-LTE, LTE-A. The flexibility for different mode of operation is achieved by a few bit settings and does not require any programming. When implemented using 65 nm standard cell library, the architecture occupies 0.166mm 2, and operates at a maximum up to 256 MHz frequency, and dissipates only 48.2 mW. The measurement results show the proposed reconfigurable rchitecture is superior in terms of area, and power than previously reported QRD architectures for similar applications in the literature.
Events in the Network Society: The Role of Pulsar and Iterative Events

This conceptual article argues for a broader view of the role of events in social systems. When analyzed as social phenomena, events can be seen as social actors that have the potential to both sustain and transform social systems. The maintenance of social systems is often reliant on iterative events, regularly occurring celebrations that tend to confirm social structures. In contrast, pulsar events have the potential to transform social structures. In this sense events can be seen as actors that have important influences on social systems, particularly in linking localized small world networks with the global space of flows. These ideas are explored through the case of Barcelona, which illustrates the interplay between these different types of events in their total portfolio, and how the extension of ritual in the sense of Collins can also contribute to the generation of new relationships and practices in the contemporary network society. Barcelona is examined as an eventful city in which the alternation of continuity through iterative events and change through pulsar events contributes to increasing the network effects of events.
Open Problem: Shifting Experts on Easy Data

A number of online algorithms have been developed that have small additional loss (regret) compared to the best \shifting expert". In this model, there is a set of experts and the comparator is the best partition of the trial sequence into a small number of segments, where the expert of smallest loss is chosen in each segment. The regret is typically dened for worst-case data / loss sequences. There has been a recent surge of interest in online algorithms that combine good worstcase guarantees with much improved performance on easy data. A practically relevant class of easy data is the case when the loss of each expert is iid and the best and second best experts have a gap between their mean loss. In the full information setting, the FlipFlop algorithm by De Rooij et al. (2014) combines the best of the iid optimal Follow-The-Leader (FL) and the worst-case-safe Hedge algorithms, whereas in the bandit information case SAO by Bubeck and Slivkins (2012) competes with the iid optimal UCB and the worst-case-safe EXP3. We ask the same question for the shifting expert problem. First, we ask what are the simple and ecient algorithms for the shifting experts problem when the loss sequence in each segment is iid with respect to a xed but unknown distribution. Second, we ask how to eciently unite the performance of such algorithms on easy data with worst-case robustness. A particular intriguing open problem is the case when the comparator shifts within a small subset of experts from a large set under the assumption that the losses in each segment are iid.
Early-Life Phthalate Exposure and Adiposity at 8 Years of Age

Background: Early-life phthalate exposure may influence child adiposity, but prior studies have not determined if there are periods of enhanced vulnerability to phthalates. Objective: To examine the relationship between child adiposity at 8 y of age and repeated urinary biomarkers of phthalate exposure from gestation through childhood to determine if there are distinct periods of vulnerability. Methods: In 219 mother–child pairs from Cincinnati, Ohio, we quantified nine urinary phthalate metabolites up to two times prenatally and six times from 1–8 y of age. We measured child body mass index (BMI), waist circumference, and percent body fat at 8 y of age. To identify periods of vulnerability, we used two statistical methods to estimate phthalate–adiposity associations at each visit, test differences in phthalate–adiposity associations across visits, and model trajectories of phthalate concentrations for children at different levels of adiposity. Results: Prenatal phthalate concentrations were not associated with excess child adiposity. Monobenzyl phthalate (MBzP) concentrations during pregnancy and childhood were inversely associated with adiposity. The associations of di(2-ethylhexyl) phthalate (∑DEHP) metabolites and monoethyl phthalate (MEP) with child adiposity depended on the timing of exposure. A 10-fold increase in ∑DEHP at 1 and 5 y was associated with a 2.7% decrease [95% confidence interval (CI): −4.8, −0.5] and 2.9% increase (95% CI: 0.3, 5.5) in body fat, respectively. MEP concentrations at 5 and 8 y of age were associated with higher child adiposity, but earlier childhood concentrations were not. Conclusion: In this cohort, we did not find evidence of an obesogenic effect of prenatal phthalate exposure. Positive associations between postnatal MEP and ∑DEHP concentrations depended on the timing of exposure. https://doi.org/10.1289/EHP1022
Young artists and the development of artistic quarters in Polish cities

The phenomenon of artistic quarters has been explored by many researchers interested in the spatial behaviours of artists in North American and Western European cities. Their analyses have often focused on the impact of this occupational group on transformations of selected urban areas: the arrival of artists as pioneers in degraded, problem neighbourhoods and the evolution of those neighbourhoods, which then attract more established artists, followed by creative professionals and non-creative gentrifiers. As over time the built environment, functions, cultural, gastronomic offer and ambiance of such areas change significantly, their progressive mainstreaming and commercialization prompt some artists to venture into new districts and spaces. The article first offers a review of existing findings with respect to artistic quarters and their transformations. The discussion of the possible stages of development of artistic quarters present in literature is followed by the application of this theoretical framework in the context of Polish cities using the examples of Krakow and Katowice. These significant regional capitals represent two major types of urban centres in Poland: a city with medieval roots, and a city which emerged during the 19th-century industrialisation process. The phases of evolution of the artistic quarters in both cities are analysed by examining the spatial perceptions of students of artistic majors. The analysis shows that the transformations of urban spaces in terms of their functions and perceptions as artistic quarters are not as straightforward and linear as earlier studies might suggest. Krakow’s more vibrant artistic life and its historic, concentric urban structure, combined with strong commercial pressures, are conducive to the development of new artistic quarters, although its traditional city centre continues to some extent to maintain its position on the artistic map of the city. In contrast, in Katowice the chaotic spatial structure of the heart of this historic industrial region makes the flow of artists more difficult and less likely, as they tend to concentrate in a poorly delineated area of the inner city. In addition, as the case studies reveal, spatial choices of artists are not only dependent on a city’s development path and its built environment but are also to a significant extent shaped by the diverse artistic backgrounds of its creatives and a host of factors linked with post-socialist transformation and neoliberal urban policies.

SPEECH INTONATION PERCEPTION DEFICITS IN MUSICAL TONE DEAFNESS (CONGENITAL AMUSIA)

TO WHAT EXTENT DO MUSIC and language share neural mechanisms for processing pitch patterns? Musical tone-deafness (amusia) provides important evidence on this question. Amusics have problems with musical melody perception, yet early work suggested that they had no problems with the perception of speech intonation (Ayotte, Peretz, & Hyde, 2002). However, here we show that about 30% of amusics from independent studies (British and French-Canadian) have difficulty discriminating a statement from a question on the basis of a final pitch fall or rise. This suggests that pitch direction perception deficits in amusia (known from previous psychophysical work) can extend to speech. For British amusics, the direction deficit is related to the rate of change of the final pitch glide in statements/ questions, with increased discrimination difficulty when rates are relatively slow. These findings suggest that amusia provides a useful window on the neural relations between melodic processing in language and music.
