Abstract
The enigmatic star KIC 8462852, informally known as “Boyajian’s Star,” has exhibited unexplained variability from both short timescale (days) dimming events, and years-long fading in the Kepler mission. No single physical mechanism has successfully explained these observations to date. Here we investigate the ultraviolet variability of KIC 8462852 on a range of timescales using data from the GALEX mission that occurred contemporaneously with the Kepler mission. The wide wavelength baseline between the Kepler and GALEX data provides a unique constraint on the nature of the variability. Using 1600 s of photon-counting data from four GALEX visits spread over 70 days in 2011, we find no coherent NUV variability in the system on 10–100 s or month timescales. Comparing the integrated flux from these 2011 visits to the 2012 NUV flux published in the GALEX-CAUSE Kepler survey, we find a 3% decrease in brightness for KIC 8462852. We find that this level of variability is significant, but not necessarily unusual for stars of similar spectral type in the GALEX data. This decrease coincides with the secular optical fading reported by Montet & Simon. We find that the multi-wavelength variability is somewhat inconsistent with typical interstellar dust absorption, but instead favors a

reddening law potentially from circumstellar dust.

Abstract
We have analyzed the Chandra archival data of NGC 1132, a well-known fossil group, i.e., a system expected to be old and relaxed long after the giant elliptical galaxy assembly. Instead, the Chandra data reveal that the hot gas morphology is disturbed and asymmetrical, with a cold front following a possible bow shock. We discuss possible origins of the disturbed hot halo, including sloshing by a nearby object, merger, ram pressure by external hotter gas, and nuclear outburst. We consider that the first two mechanisms are likely explanations for the disturbed hot halo, with a slight preference for a minor merger with a low impact parameter because of the match with simulations and previous optical observations. In this case, NGC 1132 may be a rare example of unusual late mergers seen in recent simulations. Regardless of the origin of the disturbed hot halo, the paradigm of the fossil system needs to be reconsidered.

Abstract
We analyze the application of star formation rate calibrations using Hα and 22 μm infrared (IR) imaging data in predicting the thermal radio component for a test sample of three edge-on galaxies (NGC 891, NGC 3044, and NGC 4631) in the Continuum Halos in Nearby Galaxies—an EVLA Survey (CHANG-ES). We use a mixture of Hα and 24 μm calibration from Calzetti et al. and a linear 22 μm only calibration from Jarrett et al. on the test sample. We apply these relations on a pixel-to-pixel basis to create thermal prediction maps in the two CHANG-ES bands: L and C band (1.5 GHz and 6.0 GHz, respectively). We analyze the resulting nonthermal spectral index maps, and find a characteristic steepening of the nonthermal spectral index with vertical distance from the disk after application of all methods. We find possible evidence of extinction in the 22 μm data as compared to 70 μm Spitzer Multiband Imaging Photometer imaging in NGC 891. We analyze a larger sample of edge-on and face-on galaxy 25–100 μm flux ratios, and find that the ratios for edge-ons are systematically lower by a factor of 1.36, a result we attribute to excess extinction in the mid-IR in edge-ons. We introduce a new calibration for correcting the Hα luminosity for dust when galaxies are edge-on or very dusty.
Mitigating Complex Dust Foregrounds in Future Cosmic Microwave Background Polarization Experiments
Authors: Hensley Brandon S. , Bull Philip 
Published: January 2018

Abstract
Polarized Galactic foregrounds are one of the primary sources of systematic error in measurements of the B-mode polarization of the cosmic microwave background (CMB). Experiments are becoming increasingly sensitive to complexities in the foreground frequency spectra that are not captured by standard parametric models, potentially affecting our ability to efficiently separate out these components. Employing a suite of dust models encompassing a variety of physical effects, we simulate observations of a future seven-band CMB experiment to assess the impact of these complexities on parametric component separation. We identify configurations of frequency bands that minimize the “model errors” caused by fitting simple parametric models to more complex “true” foreground spectra, which bias the inferred CMB signal. We find that: (a) fits employing a simple two-parameter modified blackbody (MBB) dust model tend to produce significant bias in the recovered polarized CMB signal in the presence of physically realistic dust foregrounds; (b) generalized MBB models with three additional parameters reduce this bias in most cases, but non-negligible biases can remain, and can be hard to detect; (c) line-of-sight effects, which give rise to frequency decorrelation, and the presence of iron grains are the most problematic complexities in the dust emission for recovering the true CMB signal. More sophisticated simulations will be needed to demonstrate that future CMB experiments can successfully mitigate these more physically realistic dust foregrounds.
Atypie sexuelle
Authors: Barbier Jacques 
Published: January 2018

La prise en compte de l’hermaphrodisme, autrement appelé atypie sexuelle, conjointement aux revendications de genre en s’en distinguant, ouvre un débat mondial sur la validité de la distinction sexuelle binaire. Nous constatons un mouvement de désexuation dans notre droit, l’exemple le plus connu étant la loi sur le mariage pour tous 1 qui a désexué le mariage et la famille. La reconnaissance par le juge d’un « sexe neutre » aurait des répercussions profondes sur les règles du droit.
Chemsex
Authors: Barbier Jacques 
Published: January 2018

Chemsex signifie littéralement l’utilisation de produits psychoactifs en contexte sexuel. Centrées principalement au départ sur les consommations de l’ecstasy et de la cocaïne les pratiques de chemsex ont évolué avec le développement exponentiel des sites Internet et des applications géolocalisées dédiés aux rencontres. Ces technologies ont rendu les rencontres sexuelles plus rapides et plus « immédiates », et favorisé leur privatisation et les contaminations infectieuses sexuellement transmissibles. L’accueil et la prise en charge des personnes ont considérablement évolué, en particulier en associant les consommateurs et les professionnels dans l’élaboration et les mises en œuvre des programmes de santé publique et de traitements individuels.

La transgression de genre en matière d’union ayant gagné la sphère légale avec l’avènement du mariage pour tous, un déplacement a eu lieu où situer l’expérience contemporaine du bizarre conjugal : sur la transgression de chiffre. Le trouble dans le chiffre, que signale l’avènement du mot « trouple » dans la langue, inexistant avant 2008 et accédant désormais aux lettres de noblesse des médias et de l’Encyclopédie libre, donne lieu à de nouvelles expériences aux oreilles analytiques. Cet article en détaille les implications et les raccroche à l’impensé des plaisirs anaux.
The English New Towns since 1946
Authors: Clapson Mark 
Published: January 2018

Au XX e siècle, le Royaume-Uni a joué un rôle pionnier dans la planification de nouvelles communautés et a été en première ligne de la diffusion internationale de la cité-jardin et du nouvel urbanisme. Or les « villages-jardins » et les écovilles actuels du Royaume-Uni ignorent des enseignements précieux fournis par l’urbanisme britannique. Ce sont des aménagements urbains à petite échelle qui incarnent l’absence de vision nationale et internationale, et la disparition d’une culture d’urbanisme dynamique et intégré, qui ont caractérisé l’État britannique ces dernières années.

The Planning of a New Town est un ouvrage publié par le London County Council (LCC) en 1960 décrivant le projet de Hook, une opération de ville nouvelle non réalisée. Cet ouvrage a exercé une influence significative sur la pratique urbanistique, au-delà même du Royaume-Uni. L’objectif principal de cet article est de montrer que son influence tient avant tout à la qualité et à l’originalité de la démarche intellectuelle de conception qui s’y déploie. L’ouvrage présente, en effet, de nouvelles manières de faire la ville et introduit de nouveaux paradigmes urbains.
Continuing Education Preferences, Facilitators, and Barriers for Nursing Home Nurses
Authors: Dyck Mary J. , Kim Myoung Jin 
Published: January 2018

Background:
The purpose of the study was to determine the continuing education needs for nursing home nurses in rural central Illinois and to determine any potential facilitators or barriers to obtaining continuing education.

Method:

Data were collected using the Educational Needs Assessment questionnaire. Descriptive statistics were computed to examine continuing education preferences, facilitators, and barriers among nursing home nurses. Independent samples
t
tests were used to compare preferences between administrative and staff nurses.

Results:
The sample included 317 nurses from 34 facilities. The five top needs were related to clinical problems. Administrative nurses had greater needs for professional issues, managerial skills, and quality improvement than staff nurses. Barriers included rural settings, need for vacation time for programs, and inadequate staffing.

Conclusion:
Continuing education needs of nursing home nurses in Illinois are similar to previous studies conducted in Arizona and North Carolina. Continuing education barriers were mostly organizational, rather than personal.

Students' Knowledge of and Interest in Older Adults: Impact of a Geriatrics Course
Authors: Lowey Susan E. 
Published: January 2018

Background:
The number of older adults living with chronic conditions is steadily increasing, so nurses must be prepared to care for the needs of this population. However, only one third of nursing education programs include a stand-alone geriatrics course.

Method:
A cross-sectional mixed-methods design was used to compare two cohorts of 46 nursing students. Knowledge, attitude, and interest in older adults were examined using an online survey. The control cohort did not complete the geriatric course.

Results:
No demographic differences were found between groups. Completing the geriatric course was not correlated with having greater aging-related knowledge. Decreased interest in working with the older adult population was found.

Conclusion:

Findings from this cross-sectional pilot study suggest that previous experience with an aging relative was associated with better aging-related knowledge. Further research exploring students' perceptions is needed to understand the relationship between the geriatric course and attitudes toward aging.

Chapitre 1 : Devenir un membre public de l’entourage politique : le rôle de figuration des conjointes d’élus en situation de représentation
Authors: Gris Christelle 
Published: January 2018

Cette contribution vise à déplacer le regard vers des acteurs peu étudiés et pourtant indispensables à la carrière politique : les membres de la famille et, plus précisément ici, les conjointes d’élus. Réinscrire ainsi l’élu dans ses entourages privés éclaire d’un jour nouveau le métier politique. En particulier, cette approche permet de rompre avec le postulat, implicitement adopté dans de nombreux travaux français de science politique, d’une stricte séparation entre vie privée et vie publique des élus au cours du processus de professionnalisation politique. À l’encontre de ce présupposé savant, le rôle de figuration tenu en situation de représentation par les femmes d’élu donne l’exemple le plus visible de l’imbrication des sphères publique et privée des hommes politiques.
HPV18 Persistence Impairs Basal and DNA Ligand–Mediated IFN-β and IFN-λ1 Production through Transcriptional Repression of Multiple Downstream Effectors of Pattern Recognition Receptor Signaling

Abstract
Although it is clear that high-risk human papillomaviruses (HPVs) can selectively infect keratinocytes and persist in the host, it still remains to be unequivocally determined whether they can escape antiviral innate immunity by interfering with pattern recognition receptor (PRR) signaling. In this study, we have assessed the innate immune response in monolayer and organotypic raft cultures of NIKS cells harboring multiple copies of episomal HPV18 (NIKSmcHPV18), which fully recapitulates the persistent state of infection. We show for the first time, to our knowledge, that NIKSmcHPV18, as well as HeLa cells (a cervical carcinoma–derived cell line harboring integrated HPV18 DNA), display marked downregulation of several PRRs, as well as other PRR downstream effectors, such as the adaptor protein stimulator of IFN genes and the transcription factors IRF1 and 7. Importantly, we provide evidence that downregulation of stimulator of IFN genes, cyclic GMP-AMP synthase, and retinoic acid–inducible gene I mRNA levels occurs at the transcriptional level through a novel epigenetic silencing mechanism, as documented by the accumulation of repressive heterochromatin markers seen at the promoter region of these genes. Furthermore, stimulation of NIKSmcHPV18 cells with salmon sperm DNA or poly(deoxyadenylic-deoxythymidylic) acid, two potent inducers of PRR signaling, only partially restored PRR protein expression. Accordingly, the production of IFN-β and IFN-λ1 was significantly reduced in comparison with the parental NIKS cells, indicating that HPV18 exerts its immunosuppressive activity through downregulation of PRR signaling. Altogether, our findings indicate that high-risk human papillomaviruses have evolved broad-spectrum mechanisms that allow simultaneous depletion of multiple effectors of the innate immunity network, thereby creating an unreactive cellular milieu suitable for viral persistence.

Published: January 2018

AbstractThere has been a progressive increase in demand for orthodontic treatment for adult patients. A 40-year-old female came to the orthodontic clinic complaining of overcrowding and midline deviation. Clinical examination showed facial asymmetry and midline deviation due to the extraction of the maxillary and mandibular first premolars of the right side. A periapical radiograph showed a severe root resorption in the maxillary central and lateral incisors. The treatment objectives were to correct the midline deviation, close the open bite, correct the bilateral posterior crossbite, and obtain a Class I relationship for the molars and canines on both sides. This case report shows a treatment approach that was effective in correcting all problems of malocclusion that the adult patient presented. The treatment results have established a new functional and stable occlusion with improvement of facial esthetics, and the roots were no shorter than before treatment.
An A-ϕ Scheme for Type-II Superconductors
Authors: Chen Tao , Kang Tong , Li Jun 
Published: January 2018

AbstractA fully discrete A-ϕ finite element scheme for a nonlinear model of type-II superconductors is proposed and analyzed. The nonlinearity is due to a field dependent conductivity with the regularized power-law form. The challenge of this model is the error estimate for the nonlinear term under the time derivative. Applying the backward Euler method in time discretisation, the well-posedness of the approximation problem is given based on the theory of monotone operators. The fully discrete system is derived by standard finite element method. The error estimate is suboptimal in time and space.
A Dispersive Numerical Model for the Formation of Undular Bores Generated by Tsunami Wave Fission
Authors: Magdalena I. 
Published: January 2018

AbstractA two-layer non-hydrostatic numerical model is proposed to simulate the formation of undular bores by tsunami wave fission. These phenomena could not be produced by a hydrostatic model. Here, we derived a modified Shallow Water Equations with involving hydrodynamic pressure using two layer approach. Staggered finite volume method with predictor corrector step is applied to solve the equation numerically. Numerical dispersion relation is derived from our model to confirm the exact linear dispersion relation for dispersive waves. To illustrate the performance of our non-hydrostatic scheme in case of linear wave dispersion and non-linearity, four test cases of free surface flows are provided. The first test case is standing wave in a closed basin, which test the ability of the numerical scheme in simulating dispersive wave motion with the correct frequency. The second test case is the solitary wave propagation as the examination of owing balance between dispersion and nonlinearity. Regular wave propagation over a submerged bar test by Beji is simulated to show that our non-hydrostatic scheme described well the shoaling process as well as the linear dispersion compared with the experimental data. The last test case is the undular bore propagation.
A Model of the Signal Transduction Process under a Delay
Authors: Kongson Jutarat , Amornsamankul Somkid 
Published: January 2018

AbstractThe signal transduction pathway is the important process of communication of the cells. It is the dynamical interaction between the ligand-receptor complexes and an inhibitor protein in second messenger synthesis. The signaling molecules are detected and bounded by receptors, typically G-Protein receptors, across the cell membrane and that in turns alerts intracellular molecules to stimulate a response or a desired consequence in the target cells. In this research, we consider a model of the signal transduction process consisting of a system of three differential equations which involve the dynamic interaction between an inhibitor protein and the ligand-receptor complexes in the second messenger synthesis. We will incorporate a delay τ in the time needed before the signal amplification process can take effect on the production of the ligand-receptor complex. We investigate persistence and stability of the system. It is shown that the system allows positive solutions and the positive equilibrium is locally asymptotically stable under suitable conditions on the system parameters.
Solution of a Nonlinear Eigenvalue Problem Using Signed Singular Values

Published: January 2018

AbstractWe propose a robust numerical algorithm for solving the nonlinear eigenvalue problem A(ƛ)x = 0. Our algorithm is based on the idea of finding the value of ƛ for which A(ƛ) is singular by computing the smallest eigenvalue or singular value of A(ƛ) viewed as a constant matrix. To further enhance computational efficiency, we introduce and use the concept of signed singular value. Our method is applicable when A(ƛ) is large and nonsymmetric and has strong nonlinearity. Numerical experiments on a nonlinear eigenvalue problem arising in the computation of scaling exponent in turbulent flow show robustness and effectiveness of our method.
High-range resolution spectral analysis of precipitation through range imaging of the Chung-Li VHF radar

Published: January 2018

Abstract. Multi-frequency range imaging (RIM) has been operated in the Chung-Li
very high-frequency (VHF) radar, located on the campus of National Central
University, Taiwan, since 2008. RIM processes the echo signals with a group
of closely spaced transmitting frequencies through appropriate inversion
methods to obtain high-resolution distribution of echo power in the range
direction. This is beneficial to the investigation of the small-scale
structure embedded in dynamic atmosphere. Five transmitting frequencies were
employed in the radar experiment for observation of the precipitating
atmosphere during the period between 21 and 23 August 2013. Using the Capon
and Fourier methods, the radar echoes were synthesized to retrieve the
temporal signals at a smaller range step than the original range resolution
defined by the pulse width, and such retrieved temporal signals were then
processed in the Doppler frequency domain to identify the atmosphere and
precipitation echoes. An analysis called conditional averaging was further
executed for echo power, Doppler velocity, and spectral width to verify the
potential capabilities of the retrieval processing in resolving small-scale
precipitation and atmosphere structures. Point-by-point correction of range
delay combined with compensation of range-weighting function effect has been
performed during the retrieval of temporal signals to improve the continuity
of power spectra at gate boundaries, making the small-scale structures in the
power spectra more natural and reasonable. We examined stratiform and
convective precipitation and demonstrated their different structured
characteristics by means of the Capon-processed results. The new element in
this study is the implementation of RIM on spectral analysis, especially for
precipitation echoes.
