Tetrabutylammonium Iodide–Promoted Thiolation of Oxindoles Using Sulfonyl Chlorides as Sulfenylation Reagents
Authors: Zhao Xia , Wei Aoqi , Lu Xiaoyu , Lu Kui
Published: August 2017

3-Sulfanyloxindoles were synthesised by triphenylphosphine-mediated transition-metal-free thiolation of oxindoles using sulfonyl chlorides as sulfenylation reagents. The above reaction was promoted by iodide anions, which was ascribed to the in situ conversion of sulfenyl chlorides into the more reactive sulfenyl iodides. Moreover, the thiolation of 3-aryloxindoles was facilitated by bases. The use of a transition-metal-free protocol, readily available reagents, and mild reaction conditions make this protocol more practical for preparing 3-sulfanyloxindoles than traditional methods.
mzStudio: A Dynamic Digital Canvas for User-Driven Interrogation of Mass Spectrometry Data
Authors: Ficarro Scott , Alexander William , Marto Jarrod
Published: August 2017

Although not yet truly ‘comprehensive’, modern mass spectrometry-based experiments can generate quantitative data for a meaningful fraction of the human proteome. Importantly for large-scale protein expression analysis, robust data pipelines are in place for identification of un-modified peptide sequences and aggregation of these data to protein-level quantification. However, interoperable software tools that enable scientists to computationally explore and document novel hypotheses for peptide sequence, modification status, or fragmentation behavior are not well-developed. Here, we introduce mzStudio, an open-source Python module built on our multiplierz project. This desktop application provides a highly-interactive graphical user interface (GUI) through which scientists can examine and annotate spectral features, re-search existing PSMs to test different modifications or new spectral matching algorithms, share results with colleagues, integrate other domain-specific software tools, and finally create publication-quality graphics. mzStudio leverages our common application programming interface (mzAPI) for access to native data files from multiple instrument platforms, including ion trap, quadrupole time-of-flight, Orbitrap, matrix-assisted laser desorption ionization, and triple quadrupole mass spectrometers and is compatible with several popular search engines including Mascot, Proteome Discoverer, X!Tandem, and Comet. The mzStudio toolkit enables researchers to create a digital provenance of data analytics and other evidence that support specific peptide sequence assignments.
Exploring Professional Help Seeking in Practicing Muslim Women with Obsessive Compulsive Disorder Washing Subtype in Australia
Authors: Mahintorabi Somayeh , Jones Mairwen , Harris Lynne
Published: August 2017

Religion and religious practices can affect Obsessive Compulsive Disorder (OCD) symptom expression and influence the way that people with OCD seek advice or treatment. This study investigated the expression of OCD symptoms and help seeking for religious OCD symptoms among practicing Muslim women. Method: Five practicing Muslim women aged 33 to 45 years who had immigrated to Australia from Iran, Iraq, Turkey, and Afghanistan and were diagnosed with OCD washing subtype (OCD-W) took part in semi-structured interviews. Data Analysis: Thematic Analysis within a scientific realist framework was employed. Results: The most common compulsions reported by participants were performing excessive washing and repeating rituals before prayer, and these behaviours were carried out to prevent being punished by God. All participants had sought help for their OCD symptoms from an Imam before seeking help from a mental health professional, and the delay between symptom onset and OCD diagnosis by a psychiatrist ranged from 5 to 13 years. Conclusion: Effective evidence-based interventions for OCD are available and increasing awareness of OCD symptoms and treatment among Imams has the potential to reduce the delay between symptom onset and access to treatment for practicing Muslims who seek help and support.
A Magnetic-Balanced Inductive Link for the Simultaneous Uplink Data and Power Telemetry
Authors: Gong Chen , Liu Dake , Miao Zhidong , Li Min
Published: August 2017

When using the conventional two-coil inductive link for the simultaneous wireless power and data transmissions in implantable biomedical sensor devices, the strong power carrier could overwhelm the uplink data signal and even saturate the external uplink receiver. To address this problem, we propose a new magnetic-balanced inductive link for our implantable glaucoma treatment device. In this inductive link, an extra coil is specially added for the uplink receiving. The strong power carrier interference is minimized to approach zero by balanced canceling of the magnetic field of the external power coil. The implant coil is shared by the wireless power harvesting and the uplink data transmitting. Two carriers (i.e., 2-MHz power carrier and 500-kHz uplink carrier) are used for the wireless power transmission and the uplink data transmission separately. In the experiments, the prototype of this link achieves as high as 65.72 dB improvement of the signal-to-interference ratio (SIR) compared with the conventional two-coil inductive link. Benefiting from the significant improvement of SIR, the implant transmitter costs only 0.2 mW of power carrying 50 kbps of binary phase shift keying data and gets a bit error rate of 1 × 10 − 7 , even though the coupling coefficient is as low as 0.005. At the same time, 5 mW is delivered to the load with maximum power transfer efficiency of 58.8%. This magnetic-balanced inductive link is useful for small-sized biomedical sensor devices, which require transmitting data and power simultaneously under ultra-weak coupling.
A Simple and Inexpensive Electrochemical Assay for the Identification of Nitrogen Containing Explosives in the Field
Authors: Erickson Jeffrey , Shriver-Lake Lisa , Zabetakis Daniel , Stenger David , Trammell Scott
Published: August 2017

We report a simple and inexpensive electrochemical assay using a custom built hand-held potentiostat for the identification of explosives. The assay is based on a wipe test and is specifically designed for use in the field. The prototype instrument designed to run the assay is capable of performing time-resolved electrochemical measurements including cyclic square wave voltammetry using an embedded microcontroller with parts costing roughly $250 USD. We generated an example library of cyclic square wave voltammograms of 12 compounds including 10 nitroaromatics, a nitramine (RDX), and a nitrate ester (nitroglycine), and designed a simple discrimination algorithm based on this library data for identification.
Hybrid Structure Multichannel All-Fiber Current Sensor
Authors: Jiang Junzhen , Zhang Hao , He Youwu , Qiu Yishen
Published: August 2017

We have experimentally developed a hybrid-structure multi-channel all-fiber current sensor with ordinary silica fiber using fiber loop architecture. According to the rationale of time division multiplexing, the sensor combines parallel and serial structures. The purpose of the hybrid-structure multi-channel all-fiber current sensor is to get more information from the different measured points simultaneously. In addition, the hybrid-structure fiber current sensor exhibited a good linear response for each channel. A three-channel experiment was performed in the study and showed that the system could detect different current positions. Each channel could individually detect the current and needed a separate calibration system. Furthermore, the three channels will not affect each other.
Full-Duplex Cooperative Sensing for Spectrum-Heterogeneous Cognitive Radio Networks
Authors: Liu Peng , Qi Wangdong , Yuan En , Wei Li , Zhao Yuexin
Published: August 2017

In cognitive radio networks (CRNs), spectrum sensing is critical for guaranteeing that the opportunistic spectrum access by secondary users (SUs) will not interrupt legitimate primary users (PUs). The application of full-duplex radio to spectrum sensing enables SU to carry out sensing and transmission simultaneously, improving both spectrum awareness and CRN throughput. However, the issue of spectrum sensing with full-duplex radios deployed in heterogeneous environments, where SUs may observe different spectrum activities, has not been addressed. In this paper, we give a first look into this problem and develop a light-weight cooperative sensing framework called PaCoSIF, which involves only a pairwise SU transmitter (SU-Tx) and its receiver (SU-Rx) in cooperation. A dedicated control channel is not required for pairwise cooperative sensing with instantaneous feedback (PaCoSIF) because sensing results are collected and fused via the reverse channel provided by full-duplex radios. We present a detailed protocol description to illustrate how PaCoSIF works. However, it is a challenge to optimize the sensing performance of PaCoSIF since the two sensors suffer from spectrum heterogeneity and different kinds of interference. Our goal is to minimize the false alarm rate of PaCoSIF given the bound on the missed detection rate by adaptively adjusting the detection threshold of each sensor. We derive an expression for the optimal threshold using the Lagrange method and propose a fast binary-searching algorithm to solve it numerically. Simulations show that, with perfect signal-to-interference-and-noise-ratio (SINR) information, PaCoSIF could decrease the false alarm rate and boost CRN throughput significantly against conventional cooperative sensing when SUs are deployed in spectrum-heterogeneous environments. Finally, the impact of SINR error upon the performance of PaCoSIF is evaluated via extensive simulations.
Economic Analysis of USN-Based Data Acquisition Systems in Tall Building Construction
Authors: Lim Hyunsu , Lee Jin , Kim Taehoon , Cho Kyuman , Cho Hunhee
Published: August 2017

The successful construction of tall buildings requires effective construction management based on various quantitative data. The recent development of ubiquitous sensor networks (USNs) enables massive amounts of data to be collected in real-time. However, the application of USN-based data acquisition systems to repetitive tasks on typical floors of tall buildings can be inefficient, because this may involve the repetitive reinstallation of sensors and the repositioning of data loggers and routers to enable continuous data transfer. To minimize this cumbersome work, a modified data acquisition method using reusable sensor nodes and mobile devices can be a useful solution. This study analyzes the economic aspects of the USN-based systems for concrete temperature monitoring by using the activity-based costing technique. The case study shows that the modified system can reduce the process cost by about 19%. It can also reduce the resource input time of management by about 55%, freeing up time for other management activities. Moreover, the cost benefits should scale up as projects increasingly require more measurement and monitoring. This study should facilitate the application of USN-based information management systems, particularly for tall building construction.
Technology Analysis of Global Smart Light Emitting Diode (LED) Development Using Patent Data
Authors: Park Sangsung , Jun Sunghae
Published: August 2017

Technological developments related to smart light emitting diode (LED) systems have progressed rapidly in recent years. In this paper, patent documents related to smart LED technology are collected and analyzed to understand the technology development of smart LED systems. Most previous studies of the technology were dependent on the knowledge and experience of domain experts, using techniques such as Delphi surveys or technology road-mapping. These approaches may be subjective and lack robustness, because the results can vary according to the selected expert groups. We therefore propose a new technology analysis methodology based on statistical modeling to obtain objective and relatively stable results. The proposed method consists of visualization based on Bayesian networks and a linear count model to analyze patent documents related to smart LED technology. Combining these results, a global hierarchical technology structure is created that can enhance the sustainability in smart LED system technology. In order to show how this methodology could be applied to real-world problems, we carry out a case study on the technology analysis of smart LED systems.
miR-133b Inhibits Cell Growth, Migration, and Invasion by Targeting MMP9 in Non-Small Cell Lung Cancer
Authors: Zhen Yan , Liu Jia , Huang Yujie , Wang Yajun , Li Wen , Wu Jun
Published: August 2017

Although increasing evidence indicates that the deregulation of microRNAs (miRNAs) contributes to tumorigenesis and invasion, little is known about the role of miR-133b in human non-small cell lung cancer (NSCLC). In the present study, we revealed that the introduction of miR-133b dramatically
suppressed NSCLC cell growth, migration, and invasion in vitro. On the contrary, miR-133b inhibitors promoted cell growth, migration, and invasion in vitro. Further studies revealed that matrix metallopeptidase 9 (MMP9) is a direct target gene of miR-133b. Silencing MMP9 inhibited cell growth,
migration, and invasion of NSCLC cells, which was consistent with the effect of miR-133b overexpression. In clinical specimens, reduced miR-133b was an unfavorable factor and negatively correlated with MMP9 expression. Our studies demonstrate that miR-133b inhibits cell growth, migration,
and invasion by targeting MMP9 in NSCLC.
Exploring the Syntax-phonology Interface: The Effect of Freestanding Form
Authors: Huang Yujing
Published: August 2017

This paper examines a case of Mandarin Tone 3 sandhi, where not being a free-standing form changes the sandhi pattern. It argues that phonological evaluation takes the type of boundaries into account, i.e. a syntactic boundary will map onto prosody only when it is a boundary of a free-standing form. This paper also shows that Mandarin Tone 3 sandhi, which was believed to be a cyclic application, can instead be derived with an output-output constraint.
Segmental Blocking in Dissimilation: An Argument for Co-Occurrence Constraints
Authors: Stanton Juliet
Published: August 2017

Most contemporary work assumes that dissimilation is motivated by featural co-occurrence constraints: a process that maps /X...X/ to [X...Y] (for example) is explained by positing a ban on co-occurring [X]s (e.g. Alderete 1997, Suzuki 1998; though cf. Bennett 2015). I show how this approach can be extended to analyze the typology of segmental blocking effects in long-distance consonant dissimilation, and provide evidence from lexical statistics in support of the analysis. Preliminary results indicate that the proposed analysis makes more accurately restrictive predictions than available alternatives.
Sonority Sequencing in Polish: the Combined Roles of Prior Bias & Experience
Authors: Jarosz Gaja , Rysling Amanda
Published: August 2017

A growing body of behavioral results demonstrates cross-linguistic sensitivity to the SSP (Daland et al. 2011; Berent et al. 2007; Berent et al. 2008; Jarosz to appear; Ren, Gao & Morgan 2010). These consistent findings suggest a role for prior bias in phonological learning, but recent modeling studies question this conclusion, showing that for some languages these preferences can be derived from the input (Daland et al. 2011; Hayes 2011). Building on these results and Jarosz’s (to appear) developmental findings for Polish, the present paper investigates adult Polish speakers’ sensitivity to the SSP experimentally and computationally. We report the results of an online acceptability judgment experiment focusing on initial clusters and present the results of computational simulations evaluating the ability of phonotactic models to predict participants’ ratings on the basis of the lexical statistics of Polish. Our main findings are that 1) SSP is predictive of adults’ ratings, 2) sonority projection arises in both attested and unattested clusters, 3) while phonotactic models have significant predictive value, they do not subsume the SSP preferences observed in the participants’ ratings, and 4) participants’ sonority sequencing preferences are not entirely compatible with the SSP, suggesting a combined effect of prior bias and experience.
Repair Strategies for failed feature specification in Japanese: Evidence from loanwords, a reversing word game, and blending
Authors: Kitaoka Daiho
Published: August 2017

This paper demonstrates repair strategies when place feature of the special moras in Japanese (the second half of a long vowel, moraic nasals, and the first half of a double consonant) fail to be specified in a usual manner. I posit three repair processes based on the observations of marked environments (loanwords, a word game called Sakasa Kotoba, blending): (i) over-application of regular structures in core lexicon, (ii) irregular structures that are produced through The Emergence of the Unmarked (TETU), and (iii) game-specific structures. I illustrate that even in marked environments, repair processes make outcome structures as unmarked as possible with these strategies. Based on the observations in the marked environments (mainly from Sakasa Kotoba), I further discuss the process of morification and underlying representations of special moras.
A Dispersion-Theoretic Account of Taiwanese CV phonotactics
Authors: Wang Sheng-Fu
Published: August 2017

In Taiwanese, oral voice consonants and nasal stops are in complementary distribution in the onset position: oral voiced consonants only precede phonemically oral vowels, and nasal stops only precede nasal vowels. Similar restriction in the distribution of these segments is not found in other languages with phonemic nasal vowels, such as French and Portuguese. Following studies showing that Taiwanese nasal vowels are fully nasalized, while French and Portuguese ones have delay in nasality (Chang et al., 2011; Delvaux et al., 2008; Parkinson, 1983), this study proposes a Dispersion-Theoretic account to connect phonetic observation about vocalic nasality to the phonotactic restrictions on voicing and nasality. Using a three-stage analysis (Flemming 2006, 2008), where Phonetic Realization is a distinct component of the grammar, the analysis is show how a cross-linguistic different in phonetic implementation of nasality is able to derive differences in surface phonotactics. The analysis also makes explicitly testable predictions about the perception and the typology of the distributions of voiced and nasal segments.
Varieties of Noisy Harmonic Grammar
Authors: Hayes Bruce
Published: August 2017

Noisy Harmonic Grammar (NHG) is a framework for stochastic grammars that uses the GEN-cum-EVAL system originated in Optimality Theory. As a form of Harmonic Grammar, NHG outputs as winner the candidate with the smallest harmonic penalty (weighted sum of constraint violations). It is stochastic because at each "evaluation time," constraint weights are nudged upward or downward by a random amount, resulting in a particular probability distribution over candidates. This “classical” form of NHG can be modified in various ways, creating alternative theories. I explore these variants in a variety of simple simulations intended to reveal key differences in their behavior; maxent grammars are also included in the comparison. In conclusion I offer hints from the empirical world regarding which of these rival theories might be correct.
Layered feet laid bare in Copperbelt Bemba tone
Authors: Breteler Jeroen , Kager René
Published: August 2017

In this paper, we identify a new type of ternarity found in bounded tone spreading in Copperbelt Bemba (Bickmore & Kula 2013).We argue that this ternarity must be metrical in nature, because it is quantity-sensitive and therefore not capturable in a straightforward counting rule.Traditional binary feet approaches to ternarity hinge on the minimal presence of unparsed syllables.However, ternarity in Copperbelt Bemba can occur in the presence of a multitude of unparsed syllables.Consequently, we argue that Copperbelt Bemba demands a larger foot constituent.We apply layered feet (Martínez-Paricio & Kager, 2013) to the analysis of the pattern, proposing that the foot in Copperbelt Bemba has an inner iamb and a monomoraic adjunct.The data is complicated by cases of falling tones on heavy syllables. We propose that these are reflections of syllable integrity violating feet, and point to other cases where this representational device has been used. Thus, we identify Copperbelt Bemba as the first instance of a blended foot, which allows more syllable integrity violations than syllabic feet, but fewer than moraic feet.
Speech production planning affects phonological variability: a case study in French liaison
Authors: Kilbourn-Ceron Oriana
Published: August 2017

Connected speech processes have played a major role in shaping theories about phonological organization, and how phonology interacts with other components of the grammar (Selkirk, 1974; Kiparsky, 1982; Kaisse, 1985; Nespor and Vogel, 1986, among others). External sandhi is subject to locality conditions, and it is more variable compared to processes applying word-internally. We suggest that an important part of understanding these two properties of external sandhi is the locality of speech production planning. Presenting evidence from French liaison, we argue that the effect of lexical frequency on variability can be understood as a consequence of the narrow window of phonological encoding during speech production planning. This proposal complements both abstract, symbolic and gestural overlap-based accounts of phonological alternations. By connecting the study of phonological alternations with the study of factors influencing speech production planning, we can derive novel predictions about patterns of variability in external sandhi, and better understand the data that drive the development of phonological theories.
Gradient Harmonicity in Compounds
Authors: Rebrus Péter , Törkenczy Miklós
Published: August 2017

Some recent approaches to morphological complexity (e.g. Hay 2001, Hay & Baayen 2005) claim that (i) morphological complexity is gradient so that even different forms that share the same affix may differ in complexity and (ii) a frequency-dependent measure of complexity is appropriate for capturing these differences. In this paper we argue that this approach can explain the unusual harmonic behaviour some compounds and compound-like words in Hungarian which unexpectedly show variation or unexpectedly do not show variation in palatal suffix harmony. We argue that this unusual harmonic behaviour is due to the fact that “compoundness” is gradient and put forward a measure of compound complexity based on the relative frequency of a compound and its constituents.
Discovery of a Rapid, Luminous Nova in NGC 300 by the KMTNet Supernova Program

Published: August 2017

We present the discovery of a rapidly evolving transient by the Korean Microlensing Telescope Network Supernova Program (KSP). KSP is a novel high-cadence supernova survey that offers deep (∼21.5 mag in BV
I bands), nearly continuous wide-field monitoring for the discovery of early and/or fast optical transients. KSP-OT-201509a, reported here, was discovered on 2015 September 27 during the KSP commissioning run in the direction of the nearby galaxy NGC 300, and stayed above detection limit for ∼22 days. We use our BV
I light curves to constrain the ascent rate, −3.7(7) mag day−1 in V, decay timescale,

days, and peak absolute magnitude,

mag. We also find evidence for a short-lived pre-maximum halt in all bands. The peak luminosity and light-curve evolution make KSP-OT-201509a consistent with a bright, rapidly decaying nova outburst. We discuss constraints on the nature of the progenitor and its environment using archival Hubble Space Telescope (HST)/ACS images and conclude with a broad discussion on the nature of the system.
Discovery of a Group of Receding, Variable Halo Stars toward Norma

Published: August 2017

We present results from spectroscopic observations of a trio of Cepheid candidates identified from K

s
-band light curves toward Norma. The spectra show that these stars are moving with a large and similar radial velocity—the heliocentric velocities are 171 ± 32 km s−1, 164 ± 37 km s−1, and 173 ± 20 km s−1. The average radial velocity is ∼169 km s−1, which is large and distinct from typical stars in the Galaxy’s stellar disk. Given the radial velocities and associated 1σ error, we find that the combined probability that these three stars are foreground Milky Way disk stars is ∼7 × 10−4%, and the probability that these are large-amplitude spotted stars in a binary is ∼10−5%. These objects at l ∼ 333° and b ∼ −1° are therefore associated with the stellar halo. The identification of these sources as Type I Cepheids is not certain, and thus the distances of these sources are not yet well established. Assuming the 3.6 μm period–luminosity relation of Type I Cepheids gives a distance of ∼78 kpc for these sources.
Attenuation Modified by DIG and Dust as Seen in M31

Published: August 2017

The spatial distribution of dust in galaxies affects the global attenuation, and hence inferred properties, of galaxies. We trace the spatial distribution of dust in five approximately kiloparsec fields of M31 by comparing optical attenuation with the total dust mass distribution. We measure the attenuation from the Balmer decrement using Integral Field Spectroscopy and the dust mass from Herschel far-IR observations. Our results show that M31's dust attenuation closely follows a foreground screen model, contrary to what was previously found in other nearby galaxies. By smoothing the M31 data, we find that spatial resolution is not the cause for this difference. Based on the emission-line ratios and two simple models, we conclude that previous models of dust/gas geometry need to include a weakly or non-attenuated diffuse ionized gas (DIG) component. Due to the variation of dust and DIG scale heights with galactic radius, we conclude that different locations in galaxies will have different vertical distributions of gas and dust and therefore different measured attenuation. The difference between our result in M31 with that found in other nearby galaxies can be explained by our fields in M31 lying at larger galactic radii than the previous studies that focused on the centers of galaxies.
On the Energetics of the
Reaction and Some Astrochemical Implications
Authors: Savin D. W. , Bhaskar R. G. , Vissapragada S. , Urbain X.
Published: August 2017

We explore the energetics of the titular reaction, which current astrochemical databases consider to be open at typical dense molecular (i.e., dark) cloud conditions. As is common for reactions involving the transfer of light particles, we assume that there are no intersystem crossings of the potential energy surfaces involved. In the absence of any such crossings, we find that this reaction is endoergic and will be suppressed at dark cloud temperatures. Updating accordingly a generic astrochemical model for dark clouds changes the predicted gas-phase abundances of 224 species by greater than a factor of 2. Of these species, 43 have been observed in the interstellar medium. Our findings demonstrate the astrochemical importance of determining the role of intersystem crossings, if any, in the titular reaction.
Stellar Stream Candidates in the Solar Neighborhood Found in the LAMOST DR3 and TGAS
Authors: Liang X. L. , Zhao J. K. , Oswalt T. D. , Chen Y. Q. , Zhang L. , Zhao G.
Published: August 2017

We have cross-matched the LAMOST DR3 with the Gaia DR1 TGAS catalogs and obtained a sample of 166,827 stars with reliable kinematics. A technique based on the wavelet transform was applied to detect significant overdensities in velocity space among five subsamples divided by spatial position. In total, 16 significant overdensities of stars with very similar kinematics were identified. Among these, four are new stream candidates and the rest are previously known groups. Both the U–V velocity and metallicity distributions of the local sample show a clear gap between the Hercules structure and the Hyades–Pleiades structure. The U–V positions of these peaks shift with the spatial position. Following a description of our analysis, we speculate on possible origins of our stream candidates.
A Likely Redback Millisecond Pulsar Counterpart of 3FGL J0838.8-2829
Authors: Halpern J. P. , Strader J. , Li M.
Published: August 2017

We obtained new optical observations of the X-ray source XMMU J083850.38−282756.8, the previously proposed counterpart of the γ-ray source 3FGL J0838.8−2829. Time-series photometry in the

band reveals periodic modulation of

mag that is characteristic of the heating of the photosphere of a low-mass companion star by a compact object. The measured orbital period is 5.14817 ± 0.00012 hr. The shape of the light curve is variable, evidently due to the effects of flaring and asymmetric heating. Spectroscopy reveals a companion of type M1 or later, having a radial velocity amplitude of 315 ± 17 km s−1, with period and phasing consistent with the heating interpretation. The mass function of the compact object is

, which allows a neutron star in a high-inclination orbit. Variable, broad Hα emission is seen, which is probably associated with a wind from the companion. These properties, as well as the X-ray and γ-ray luminosities at the inferred distance of

, are consistent with a redback millisecond pulsar in its non-accreting state. A search for radio pulsations is needed to confirm this interpretation and derive complete system parameters for modeling, although absorption by the ionized wind could hinder such detection.
Individual Dynamical Masses of Ultracool Dwarfs*

Authors: Dupuy Trent J. , Liu Michael C.
Published: August 2017

We present the full results of our decade-long astrometric monitoring programs targeting 31 ultracool binaries with component spectral types M7–T5. Joint analysis of resolved imaging from Keck Observatory and Hubble Space Telescope and unresolved astrometry from CFHT/WIRCam yields parallactic distances for all systems, robust orbit determinations for 23 systems, and photocenter orbits for 19 systems. As a result, we measure 38 precise individual masses spanning 30–115

. We determine a model-independent substellar boundary that is ≈70

in mass (≈L4 in spectral type), and we validate Baraffe et al. evolutionary model predictions for the lithium-depletion boundary (60

at field ages). Assuming each binary is coeval, we test models of the substellar mass–luminosity relation and find that in the L/T transition, only the Saumon & Marley “hybrid” models accounting for cloud clearing match our data. We derive a precise, mass-calibrated spectral type–effective temperature relation covering 1100–2800 K. Our masses enable a novel direct determination of the age distribution of field brown dwarfs spanning L4–T5 and 30–70

. We determine a median age of 1.3 Gyr, and our population synthesis modeling indicates our sample is consistent with a constant star formation history modulated by dynamical heating in the Galactic disk. We discover two triple-brown-dwarf systems, the first with directly measured masses and eccentricities. We examine the eccentricity distribution, carefully considering biases and completeness, and find that low-eccentricity orbits are significantly more common among ultracool binaries than solar-type binaries, possibly indicating the early influence of long-lived dissipative gas disks. Overall, this work represents a major advance in the empirical view of very low-mass stars and brown dwarfs.
Correlation Investigation of Radio and Optical Variations in a Large Sample of Fermi Blazars
Authors: Zhang B. K. , Zhao X. Y. , Zhang L. , Dai B. Z.
Published: August 2017

We have performed a correlation analysis of radio and optical variations in a large sample of Fermi blazars, of which there are 36 flat spectrum radio quasars and 34 BL Lacertae objects. The discrete cross-correlation function (DCF) method has been employed to investigate the correlation and the possible time lag. A clear correlation has been found in 55 sources (78.6% of the sample sources). It is confirmed that the variations in optical bands lead those in radio bands by several days to several hundred days. In four cases, optical flares are found to occur simultaneously with the radio flares. A jet-in-shock model has been used to explain these results. We estimate that the lag between the radio and optical bands may range from 3 days to 2.4 years. The DCF analysis results are consistent with expectations.

Objective.

To date, there are no standardized disease activity tools for systemic juvenile idiopathic arthritis (sJIA). We developed a core set of disease activity measures for sJIA.

Methods.

We conducted a validation study in patients with sJIA recruited from 3 Canadian institutions. Disease activity scores were based on questionnaires, clinical factors, and laboratory measures. The physician’s global assessment was our criterion standard. We determined the strength of association of each item with the criterion standard. We then surveyed international experts to determine the top 10 items. Finally, we used the experts’ responses to generate a proposed core set of disease activity measures.

Results.

We enrolled 57 subjects — 26 with moderately or severely active disease, and 31 with mildly active or inactive disease. Items that most strongly correlated with the criterion standard were number of active joints (r = 0.79), parent’s global assessment of disease activity (r = 0.53), erythrocyte sedimentation rate (ESR; r = 0.62), and C-reactive protein (CRP; r = 0.61). The response rate from international experts was 82% (154/187). Items with the most votes, in descending order, were number of active joints, number of days with fever in the preceding 2 weeks, patient’s and parent’s global assessments of disease activity, sJIA rash, ESR, CRP, and hemoglobin level.

Conclusion.

We propose a core set of items for measuring disease activity in sJIA. Future research should be aimed at further validation of this core set in the international context.

Le sens qu’une institution peut prendre exige un récit qui la situe comme représentative du système culturel auquel elle appartient. Le mythe fonctionnaliste dominant les sociétés modernes met les travailleurs sociaux dans une position subjective paradoxale. Ainsi le travail social aurait à traiter ce par quoi il est lui-même affecté : l’affaiblissement de la capacité à mettre en récit ce qui fonde une existence à l’articulation de l’individu et du collectif. Pour mettre en perspective le mythe fondateur du travail social laïc en France, je me suis intéressé à l’institution de l’État providence après la Libération.
L’expérience compromise

Published: August 2017

Éducatrice spécialisée en foyer de vie, mes observations témoignent de pratiques qui font obstacle à la mise en œuvre des potentialités des personnes accompagnées. Le travail de recherche révèle que l’accompagnement s’efface au profit de pratiques de substitution et de contrôle. Privées d’expérience, les personnes avancent dans l’ignorance de capacités rendues invisibles pour elles-mêmes et pour les professionnels.
Simulation study of wake field excitation in interaction of intense laser and magnetized plasma: Half-sine pulse shape (HSPS) and trapezoid pulse shape (TPS)
Authors: Rahimian Amir , Zahed Hossien
Published: August 2017

We have conducted particle-in-cell (PIC) simulations of a linearly polarized intensive laser pulse with two different envelopes propagating through a homogeneous fully ionized cold plasma. It is shown that the amplitude of the wake field depends on laser wavelength, pulse duration, electron number density and envelope shape. We have also simulated the effect of applying a longitudinal magnetic field on the wake field excitation process. It is observed that magnetic field enhances the wake field and increases its intensity in all cases. Our results are in agreement with the analytical results presented by Askari and Shahidani [Opt. Laser Technol.45, 613–619 (2013)] and can help choosing the optimum values of affecting laser and plasma parameters in order to reach high accelerating wake electric fields.
Variabilidad de la precipitación y su relación con los rendimientos agrícolas en una región semiárida de la llanura pampeana (Argentina)
Authors: Soledad Brendel Andrea , Yael Bohn Vanesa , Piccolo María Cintia
Published: August 2017

El objetivo de este estudio fue analizar la alternancia de períodos secos, húmedos y normales durante los años 1970-2012 en una región semiárida de la llanura pampeana argentina. La evolución de los rendimientos de un cultivo de secano (trigo) se analizó como indicador de dicha alternancia, durante el período 2000-2012. Se utilizó el Índice Estandarizado de Precipitación y Evapotranspiración (en inglés SPEI) y se analizó la superficie sembrada, cosechada y los rendimientos del cultivo de trigo. Los períodos normales según el SPEI fueron los más frecuentes en el área de estudio mientras que hubo una desigual proporción en la ocurrencia de eventos se cos y húmedos. El año 2001 fue húmedo y los años 2008 y 2009 fueron secos. Durante estos últimos, disminuyeron los rendimientos y la extensión de la superficie cosechada de trigo, mostrándose como indicadores de la alternancia de períodos secos y húmedos.
La dinámica del paisaje en la Serra d’Aitana (Alacant, España): síntesis de transformaciones históricas en una montaña mediterránea (1600-2010)
Authors: Giménez-Font Pablo , Marco Molina Juan Antonio
Published: August 2017

El estudio sobre la trayectoria histórica de los ecosistemas es necesario para comprender su capacidad de respuesta ante determinadas perturbaciones. A partir de esta idea, el presente trabajo analiza las transformaciones del paisaje ocurridas en los últimos 400 años en la Serra d’Aitana, un espacio singular que reúne las principales características ecológicas e históricas de la montaña media mediterránea europea. El artículo sintetiza los resultados de una larga investigación en la que se han empleado numerosas fuentes documentales, orales y de trabajo de campo. Los resultados se ofrecen en cinco periodos (hasta 1650, 1650-1850, 1850-1920, 1920-1960 y 1960-2010) que permiten comprobar la intensidad de los cambios ocurridos a partir de cinco procesos: expansión de la superficie agraria, ganadería, incendios forestales, aprovechamientos forestales y repoblaciones forestales. De esta forma se obtiene un marco analítico general que permitirá centrar posteriores estudios de detalle en las montañas béticas valencianas.
Medición y cartografía del impacto socialmente percibido ante industrias contaminantes con un estimador de densidad núcleo (kernel) y SIG: aplicación al caso del complejo industrial Ventanas, Chile
Authors: Moreno Jiménez Antonio , Fuenzalida Díaz Manuel
Published: August 2017

Los efectos ambientales derivados de actividades humanas ocasionan los llamados campos de externalidades en el entorno de ellas, manifestándose bien como emisiones o impactos físicos, bien como vivencias negativas afectando a la población. La medición de ese malestar social y su expresión espacial constituye el asunto central de esta contribución, en la que se aborda el caso de los residentes próximos a un gran complejo industrial en Chile. A tal fin se diseñó y realizó una encuesta domiciliaria para determinar la percepción de varios impactos ambientales, que luego fue georreferenciada. Para establecer la magnitud del malestar socio-espacial se recurrió a la técnica de los estimadores de densidad núcleo (kernel), que permiten generar con SIG superficies y expresivos mapas representativos de las diversas experiencias negativas, así como un indicador sintético de las mismas. Con ello se pretende aportar una vía nueva para aprehender, en cantidad y en lugar, esos elusivos efectos, aplicable en labores como la evaluación de impactos ambientales.

Boswell Reading Boswell: a Chapter in Autobiographical Misconstruction
Authors: Ingram Allan
Published: August 2017

James Boswell, like any contemporary Scottish or English gentleman, was a wide reader, schooled in the classics and, of course, in the greats of the vernacular, especially Shakespeare, Addison and, of his immediate contemporaries, Johnson. Boswell's reading, however, was not at all systematic, or systematisable. Except in his legal practice, where he often records reading solidly and unenthusiastically for a particular case, he tended to read as the mood took him, and often altogether without solidity. But Boswell's reading was in one respect distinctive, even thorough, and certainly directed towards understanding one thing as clearly as possible, even if filled with misreadings and misconstructions. He read his own journal, and the intention was to understand himself. My point is that Boswell made a conscious and sustained attempt with the Life of Johnson to edit himself into a less mockable, less amusing, less frivolous narrative figure for the purposes of public consumption, and thereby into a more consistent, less shaming, less volatile individual for his own consumption than in the journals that provided the fundamental reading material for the lives of Boswell and of Johnson
Reading as Ideology: Robinson Crusoe, Spiritual Autobiography and the Bible
Authors: Sim Stuart
Published: August 2017

Reading lies at the very heart of the nonconformist experience in seventeenth-and eighteenth-century England. It is through individual reading of the Bible and the tradition of spiritual autobiography that feeds through the works of writers such as John Bunyan, that the nonconformist individual learns how to structure his or her life. In modern terms of reference, someone like John Bunyan becomes a role model that others can hope to emulate, with his own autobiography Grace Abounding to the Chief of Sinners as a training manual for would-be electees from a nonconformist background. Robinson Crusoe gives no particular hint as to his reading in this area, but his presentation of his life in the characteristic form of spiritual autobiography suggests someone steeped in that cultural discourse: a discourse heavily identified with nonconformism by this stage. Reading is here an act of negotiation with one's belief system, by which nonconformists can test its validity. Given that this belief system clashes with the dominant ideology of the time, that turns reading into something bordering on subversion; Crusoe's “enthusiasm” on being led to the conversionrevealing passage of Scripture indicating where this can lead
De l’onanisme moral, ou la médecine des Lumières face à la fureur de lire
Authors: Vot Valérie Le
Published: August 2017

Leselust (soif de lecture), Lesesucht (manie de lecture), Lesewut (fureur de lire) : les discours sur la prétendue « révolution de la lecture » qui prend place dans la seconde moitié du XVIIIe siècle dans les territoires allemands empruntent beaucoup au lexique médical. Par ce recours, le discours sur la lecture, volontiers imprécatoire et émotionnel, se pare d’objectivité scientifique et souligne la gravité de la situation, comparée à une épidémie (Leseseuche) qui réclame une réponse thérapeutique rapide et radicale. C’est dans le discours des médecins qu’on trouvera les réflexions les plus avancées sur les mécanismes de l’imagination, excitée par la lecture et rendue responsable de tous les maux, ainsi que les protocoles thérapeutiques les plus précis. Les écrits du médecin sans doute le plus influent des Lumières allemandes, Christoph Wilhelm Hufeland (1762-1836), se trouvent donc au cœur de l’analyse
O príncipe disfarçado no teatro romanesco de Gil Vicente
Authors: Nepomuceno Luís André
Published: August 2017

A partir de 1521, Gil Vicente abandona seu teatro devocional, para se dedicar a motivos alegóricos e profanos, inaugurando nova fase em sua carreira. Movido pela leitura dos romances de cavalaria que se espalhavam pela península, o dramaturgo compôs uma série de pelo menos quatro peças dedicadas a D. João III, cujo tema central (ou circunstancial) é o disfarce de um príncipe nas classes baixas, junto ao posterior desvelamento de sua natureza nobre. Partindo de um corpus específico do teatro vicentino (as peças Rubena, Viúvo, Amadis de Gaula e Dom Duardos), o presente trabalho busca elucidar os motivos históricos que percorrem o tema do ‘príncipe disfarçado’, considerando o programa de elogio da monarquia, proposto por Gil Vicente, bem como uma análise da natureza do amor humanista, veiculado por poetas e filósofos do quinhentismo. Entende-se que o disfarce nas classes baixas revela a essência aristocrática do cortesão mas também uma experiência ritualística no percurso do amor espiritualizado.

Primary peritoneal carcinoma (PPC) is rare tumor, traditionally treated with surgical debulking and systemic chemotherapy (SC) with 30% five-year survival rate. Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) may improve long-term survival. Thirty patients with PPC were identified. Twenty-three patients underwent CRS/HIPEC as initial treatment (group I) and 7 for recurrent disease (group II). Peritoneal cancer index (PCI), cytoreduction scores (CC), overall survival (OS) and progressionfree survival (PFS) were estimated using Kaplan-Meier survival analysis. FIGO stages II/III/IV at diagnosis were 2/20/7 (1 was not classified). Median time from diagnosis to CRS/HIPEC was 2 months and 8 months in groups I and II, respectively. PCI≥20 was seen in 16 (70%) and 4 (57%) in groups I and II, respectively. Complete cytoreduction (CC 0-1) was achieved in 30/32 (94%) CRS/HIPEC procedures. Median follow-up was 39 months (range: 11-250). PFS at 1, 3, 5-years was 80%, 75%, 59%, respectively. OS 1, 3, 5- years from CRS/HIPEC was 90%, 68%, 55%. CRS/HIPEC and adjuvant SC provides five-year survival rate higher than previously reported for PPC patients who received conventional therapy with surgical debulking and SC.
