Overexpression of Aristaless-Like Homeobox-4 Inhibits Proliferation, Invasion, and EMT in Hepatocellular Carcinoma Cells
Authors: Shi Yao , Sun Xiaoke , He Xiafen
Published: January 2017

Aristaless-like homeobox-4 (ALX4), a member of the Aristaless-like homeobox family, has been found to be involved in tumor cell proliferation, migration, and invasion. However, the role of ALX4 in hepatocellular carcinoma (HCC) remains largely unclear. Therefore, in this study we investigated the effects of ALX4 on HCC. The study results indicated that the expression of ALX4 was downregulated in HCC tissues and cell lines. Furthermore, we demonstrated that overexpression of ALX4 inhibited the proliferation, invasion, and epithelialmesenchymal transition (EMT) in HCC cells. We also found that ALX4 had an inhibitory effect on the sonic hedgehog (Shh) signaling pathway. Taken together, the results suggest that ALX4 may be a promising target for HCC treatment.

Authors: Zhang Li , Duan Hong-bin , Yang Yun-sheng
Published: January 2017

Rap2B, a member of the Ras family of small GTP-binding proteins, was found to be highly expressed in various human tumors and plays an important role in the development of tumors. However, the function of Rap2B in hepatocellular carcinoma (HCC) remains unclear. Therefore, in this study,
we investigated the biological functions of Rap2B in HCC and the potential underlying mechanisms. Our results indicated that Rap2B was highly expressed in HCC tissues and cell lines. Rap2B silencing obviously inhibited the proliferation, migration, and invasion of HCC cells, as well as attenuated
xenografted tumor growth in vivo. Furthermore, Rap2B silencing greatly reduced the expression levels of phosphorylated focal adhesion kinase (p-FAK), matrix metalloproteinase-2 (MMP-2), and MMP-9 in HCC cells. In conclusion, our data suggest that Rap2B silencing inhibits the proliferation
and invasion in HCC cells. Thus, Rap2B may have potential as a treatment for HCC.

Published: January 2017

The role of miRNAs in the radiosensitivity of glioma cells and the underlying mechanism is still far from clear. In the present study, we detected six downregulated and seven upregulated miRNAs in the serum after radiotherapy compared with paired serum samples before radiotherapy via
miRNA panel PCR. Among these, miR-17-5p was highly reduced (fold change=4.21). Further, we validated the levels of miR-17-5p in all serum samples with qRT-PCR. In addition, statistical analysis suggested that a reduced miR-17-5P level was positively associated with advanced clinical stage
of glioma, incidence of relapse, and tumor differentiation. Moreover, we provided evidence that irradiation markedly activated autophagy and decreased miR-17-5p in the glioma cell line. Further, we demonstrated that irradiation-induced autophagy activation was mediated by beclin-1, and downregulation
of beclin-1 via siRNA significantly abolished the irradiation-activated autophagy. Interestingly, we demonstrated that miR-17-5p could directly target beclin-1 via luciferase gene reporter assay. Exotic expression of miRNA-17-5p decreased autophagy activity in vitro. In nude mice, miRNA-17-5p
upregulation sensitized the xenograft tumor to irradiation and suppressed irradiation-induced autophagy. Finally, pharmacal inhibition of autophagy markedly enhanced the cytotoxicity of irradiation in RR-U87 cells.

Published: January 2017

The identification of reliable predictors of chemotherapy sensitivity and early screening of adenocarcinoma of gastroesophageal junction (AGEJ) patients who are resistant to chemotherapy has become an important area of clinical and translational research. We aimed to investigate the
predictive value of seven cancer-associated cellular proteins for neoadjuvant chemotherapy in AGEJ patients. Clinical data of 93 patients who received neoadjuvant chemotherapy for locally advanced AGEJ between June 2010 and December 2014 were reviewed. All patients were administered the combination
regimen of S-1 and oxaliplatin (SOX). Expression of P-glycoprotein (P-gp), glutathione S-transferase- (GST-), topoisomerase II (topo II), multidrug resistance gene-associated protein (MRP), lung resistance-related protein (LRP), Ki-67, and p53 was determined by immunohistochemistry (IHC) in
AGEJ tissues before neoadjuvant chemotherapy. Chemotherapeutic efficacy was evaluated according to RECIST 1.0 standards and histopathological results, and the relationship between the expression of the cellular proteins and chemotherapy efficacy was analyzed. The SOX regimen was associated
with an overall response rate of 46.2%. The frequency of expression of the seven cancer-associated factors in the AGEJ tissues was as follows: P-gp, 64.5%; GST-, 39.8%; topo II, 72.0%; MRP, 33.3%; LRP, 68.8%; Ki-67, 62.4%; and p53, 40.9%. Expression of Ki-67 (p=0.003) and p53 (p=0.009)
was significantly correlated with chemotherapy sensitivity. Elevated Ki-67 expression and decreased p53 expression predict for SOX insensitivity in AGEJ, and the cellular expression of these respective proteins may provide a useful reference for designing individualized chemotherapy regimens
for AGEJ patients in the future.

Published: January 2017

Armadillo repeat-containing protein 8 (ARMc8) is a key factor in regulating cell migration, proliferation, tissue maintenance, and tumorigenesis. However, its role in bladder cancer remains unknown. Thus, in this study we sought to investigate the effect of ARMc8 on the epithelial-to-mesenchymal
transition (EMT) progress in bladder cancer cells induced by transforming growth factor-1 (TGF-1). Our results found that ARMc8 was highly expressed in bladder cancer cell lines. ARMc8 silencing inhibited the TGF-1-induced migration and invasion and suppressed the EMT progress in bladder cancer
cells. Furthermore, ARMc8 silencing inhibited the TGF-1-induced expression of -catenin, cyclin D1, and c-myc in bladder cancer cells. In conclusion, the present study demonstrates a novel function for ARMc8, which acts as a mediator for TGF-1-induced cell migration/invasion through modulation
of the Wnt/-catenin signaling pathway in bladder cancer cells. This study suggests that ARMc8 may be a potential therapeutic target for the development of therapies for bladder cancer.

Authors: Zhao Ping , Guan Hai-Tao , Dai Zhi-Jun , Ma Yu-Guang , Liu Xiao-Xu , Wang Xi-Jing
Published: January 2017

Tripartite motif-containing protein 37 (TRIM37), a new member of the RING-B-box-coiled-coil (RBCC) subfamily of zinc finger proteins, was found to be involved in the development and progression of several cancers. However, the expression pattern and biological functions of TRIM37 in
colorectal cancer (CRC) remain unknown. Therefore, in the present study, we examined the expression pattern of TRIM37 in CRC and investigated the function of TRIM37 in the progression of CRC. Our results showed that TRIM37 expression was upregulated in CRC cell lines. Knockdown of TRIM37 inhibited
CRC cell proliferation and tumor growth in vivo. Furthermore, knockdown of TRIM37 inhibited the migration and invasion in CRC cells. Last, knockdown of TRIM37 inhibited the protein level expression of -catenin, cyclin D1, and c-Myc in CRC cells. In conclusion, these results demonstrate that
TRIM37 may play an important role in the proliferation, invasion, and tumorigenesis of CRC cells. Thus, TRIM37 may be a potential therapeutic target for the treatment of CRC.
STAR-FORMING ACTIVITY IN THE H ii REGIONS ASSOCIATED WITH THE IRAS 17160–3707 COMPLEX
Authors: Nandakumar G. , Veena V. S. , Vig S. , Tej A. , Ghosh S. K. , Ojha D. K.
Published: January 2017

We present a multiwavelength investigation of star formation activity toward the southern H ii regions associated with IRAS 17160–3707, located at a distance of 6.2 kpc with a bolometric luminosity of 8.3 × 105
L
⊙. The ionized gas distribution and dust clumps in the parental molecular cloud are examined in detail using measurements at infrared, submillimeter and radio wavelengths. The radio continuum images at 1280 and 610 MHz obtained using the Giant Metrewave Radio Telescope reveal the presence of multiple compact sources as well as nebulous emission. At submillimeter wavelengths, we identify seven dust clumps and estimate their physical properties such as temperature: 24–30 K, mass: 300–4800 M
⊙ and luminosity: 9–317 × 102
L
⊙ using modified blackbody fits to the spectral energy distributions (SEDs) between 70 and 870 μm. We find 24 young stellar objects (YSOs) in the mid-infrared, with a few of them coincident with the compact radio sources. The SEDs of the YSOs have been fitted by the Robitaille models and the results indicate that those having radio compact sources as counterparts host massive objects in early evolutionary stages with best fit age ≤0.2 Myr. We compare the relative evolutionary stages of clumps using various signposts such as masers, ionized gas, presence of YSOs and infrared nebulosity, and find six massive star-forming clumps and one quiescent clump. Of the former, five are in a relatively advanced stage and one in an earlier stage.
SPATIAL DISTRIBUTION OF MG-RICH EJECTA IN LMC SUPERNOVA REMNANT N49B
Authors: Park Sangwook , Bhalerao Jayant
Published: January 2017

The supernova remnant (SNR) N49B in the Large Magellanic Cloud is a peculiar example of a core-collapse SNR that shows the shocked metal-rich ejecta enriched only in Mg without evidence for a similar overabundance in O and Ne. Based on archival Chandra data, we present results from our extensive spatially resolved spectral analysis of N49B. We find that the Mg-rich ejecta gas extends from the central regions of the SNR out to the southeastern outermost boundary of the SNR. This elongated feature shows an overabundance for Mg similar to that of the main ejecta region at the SNR center, and its electron temperature appears to be higher than the central main ejecta gas. We estimate that the Mg mass in this southeastern elongated ejecta feature is ∼10% of the total Mg ejecta mass. Our estimated lower limit of >0.1 M
⊙ on the total mass of the Mg-rich ejecta confirms the previously suggested large mass for the progenitor star (M ≳ 25 M
⊙). We entertain scenarios of an SNR expanding into a nonuniform medium and an energetic jet-driven supernova in an attempt to interpret these results. However, with the current results, the origins of the extended Mg-rich ejecta and the Mg-only-rich nature of the overall metal-rich ejecta in this SNR remain elusive.
THE SHAPE OF SOLAR CYCLES DESCRIBED BY A SIMPLIFIED BINARY MIXTURE OF GAUSSIAN FUNCTIONS
Authors: Li F. Y. , Xiang N. B. , Kong D. F. , Xie J. L.
Published: January 2017

Sunspot cycles usually present a double-peak structure. This work is devoted to using a function to describe the shape of sunspot cycles, including bimodal cycles, and we find that the shape of sunspot cycles can be described by a binary mixture of Gaussian functions with six parameters, two amplitudes, two gradients of curve, and two rising times, and the parameters could be reduced to three. The fitting result of this binary mixture of Gaussian functions is compared with some other functions used previously in the literature, and this function works pretty well, especially at cycle peaks. It is worth mentioning that the function can describe well the shape of those sunspot cycles that show double peaks, and it is superior to the binary mixture of the Laplace functions that was once utilized. The Solar Influences Data Analysis Center, on behalf of the World Data Center, recently issued a new version (version 2) of sunspot number. The characteristics of sunspot cycles are investigated, based on the function description of the new version.
A HUNT FOR MASSIVE STARLESS CORES
Authors: Kong Shuo , Tan Jonathan C. , Caselli Paola , Fontani Francesco , Liu Mengyao , Butler Michael J.
Published: January 2017

We carry out an ALMA

(3-2) and 1.3 mm continuum survey of 32 high-mass surface density regions of seven infrared dark clouds, with the aim of finding massive starless cores that may form the initial conditions for the formation of massive stars. Cores showing strong

(3-2) emission are expected to be highly deuterated and indicative of early, potentially pre-stellar stages of star formation. We also present maps of these regions in ancillary line tracers, including C18O(2-1), DCN(3-2), and DCO+(3-2). Over 100

cores are identified with our newly developed core-finding algorithm, based on connected structures in position–velocity space. The most massive core has

(potentially

) and so may be representative of the initial conditions or early stages of massive star formation. The existence and dynamical properties of such cores constrain massive star formation theories. We measure the line widths and thus velocity dispersion of six of the cores with strongest

(3-2) line emission, finding results that are generally consistent with virial equilibrium of pressure confined cores.
BOOSTED TIDAL DISRUPTION BY MASSIVE BLACK HOLE BINARIES DURING GALAXY MERGERS FROM THE VIEW OF N-BODY SIMULATION
Authors: Li Shuo , Liu F. K. , Berczik Peter , Spurzem Rainer
Published: January 2017

Supermassive black hole binaries (SMBHBs) are productions of the hierarchical galaxy formation model. There are many close connections between a central SMBH and its host galaxy because the former plays very important roles on galaxy formation and evolution. For this reason, the evolution of SMBHBs in merging galaxies is a fundamental challenge. Since there are many discussions about SMBHB evolution in a gas-rich environment, we focus on the quiescent galaxy, using tidal disruption (TD) as a diagnostic tool. Our study is based on a series of numerical, large particle number, direct N-body simulations for dry major mergers. According to the simulation results, the evolution can be divided into three phases. In phase I, the TD rate for two well separated SMBHs in a merging system is similar to that for a single SMBH in an isolated galaxy. After two SMBHs approach close enough to form a bound binary in phase II, the disruption rate can be enhanced by ∼2 orders of magnitude within a short time. This “boosted” disruption stage finishes after the SMBHB evolves to a compact binary system in phase III, corresponding to a reduction in disruption rate back to a level of a few times higher than in phase I. We also discuss how to correctly extrapolate our N-body simulation results to reality, and the implications of our results to observations.
THE GALACTIC NOVA RATE REVISITED
Authors: Shafter A. W.
Published: January 2017

Despite its fundamental importance, a reliable estimate of the Galactic nova rate has remained elusive. Here, the overall Galactic nova rate is estimated by extrapolating the observed rate for novae reaching

to include the entire Galaxy using a two component disk plus bulge model for the distribution of stars in the Milky Way. The present analysis improves on previous work by considering important corrections for incompleteness in the observed rate of bright novae and by employing a Monte Carlo analysis to better estimate the uncertainty in the derived nova rates. Several models are considered to account for differences in the assumed properties of bulge and disk nova populations and in the absolute magnitude distribution. The simplest models, which assume uniform properties between bulge and disk novae, predict Galactic nova rates of ∼50 to in excess of 100 per year, depending on the assumed incompleteness at bright magnitudes. Models where the disk novae are assumed to be more luminous than bulge novae are explored, and predict nova rates up to 30% lower, in the range of ∼35 to ∼75 per year. An average of the most plausible models yields a rate of

yr−1, which is arguably the best estimate currently available for the nova rate in the Galaxy. Virtually all models produce rates that represent significant increases over recent estimates, and bring the Galactic nova rate into better agreement with that expected based on comparison with the latest results from extragalactic surveys.
OSCILLATING FILAMENTS. I. OSCILLATION AND GEOMETRICAL FRAGMENTATION
Authors: Gritschneder Matthias , Heigl Stefan , Burkert Andreas
Published: January 2017

We study the stability of filaments in equilibrium between gravity and internal as well as external pressure using the grid-based AMR code RAMSES. A homogeneous, straight cylinder below a critical line mass is marginally stable. However, if the cylinder is bent, such as with a slight sinusoidal perturbation, an otherwise stable configuration starts to oscillate, is triggered into fragmentation, and collapses. This previously unstudied behavior allows a filament to fragment at any given scale, as long as it has slight bends. We call this process “geometrical fragmentation.” In our realization, the spacing between the cores matches the wavelength of the sinusoidal perturbation, whereas up to now, filaments were thought to be only fragmenting on the characteristic scale set by the mass-to-line ratio. Using first principles, we derive the oscillation period as well as the collapse timescale analytically. To enable a direct comparison with observations, we study the line-of-sight velocity for different inclinations. We show that the overall oscillation pattern can hide the infall signature of cores.
STACKING CAUSTIC MASSES FROM GALAXY CLUSTERS
Authors: Gifford Daniel , Kern Nicholas , Miller Christopher J.
Published: January 2017

Ongoing and future spectroscopic surveys will measure numerous galaxy redshifts within tens of thousands of galaxy clusters. However, the sampling within these clusters will be low,

per cluster. With such data, it will be difficult to achieve accurate and precise mass estimates for individual clusters using phase-space mass estimation techniques. We develop and test a new stacking algorithm based on the caustic technique, which reduces the mass scatter in

for ensemble clusters from 70% for individual clusters to less than 10% for ensemble clusters with only 15 galaxies per cluster and 100 clusters per ensemble. With

galaxies per ensemble phase space, the escape-velocity edge becomes readily identifiable and the presence of interloping galaxies is minimized. We develop and test an algorithm to trace the projected phase-space surface directly, which results in minimally biased dynamical mass estimates. We then quantify how binning and sampling affect the phase-space-based mass estimates when using an observational proxy that incorporates realistic mass scatter, like richness, and find the added uncertainty in the binning procedure has minimal influence on the resulting bias and scatter of the stacked mass estimates.
MAGNETIC ACTIVITY ANALYSIS FOR A SAMPLE OF G-TYPE MAIN SEQUENCE KEPLER TARGETS
Authors: Mehrabi Ahmad , He Han , Khosroshahi Habib
Published: January 2017

The variation of a stellar light curve owing to rotational modulation by magnetic features (starspots and faculae) on the star’s surface can be used to investigate the magnetic properties of the host star. In this paper, we use the periodicity and magnitude of the light-curve variation as two proxies to study the stellar magnetic properties for a large sample of G-type main sequence Kepler targets, for which the rotation periods were recently determined. By analyzing the correlation between the two magnetic proxies, it is found that: (1) the two proxies are positively correlated for most of the stars in our sample, and the percentages of negative, zero, and positive correlations are 4.27%, 6.81%, and 88.91%, respectively; (2) negative correlation stars cannot have a large magnitude of light-curve variation; and (3) with the increase of rotation period, the relative number of positive correlation stars decreases and the negative correlation one increases. These results indicate that stars with shorter rotation period tend to have positive correlation between the two proxies, and a good portion of the positive correlation stars have a larger magnitude of light-curve variation (and hence more intense magnetic activities) than negative correlation stars.
GLOBAL SIMULATIONS OF GALACTIC WINDS INCLUDING COSMIC-RAY STREAMING
Authors: Ruszkowski Mateusz , Yang H.-Y. Karen , Zweibel Ellen
Published: January 2017

Galactic outflows play an important role in galactic evolution. Despite their importance, a detailed understanding of the physical mechanisms responsible for the driving of these winds is lacking. In an effort to gain more insight into the nature of these flows, we perform global three-dimensional magnetohydrodynamical simulations of an isolated Milky Way-size starburst galaxy. We focus on the dynamical role of cosmic rays (CRs) injected by supernovae, and specifically on the impact of the streaming and anisotropic diffusion of CRs along the magnetic fields. We find that these microphysical effects can have a significant effect on the wind launching and mass loading factors, depending on the details of the plasma physics. Due to the CR streaming instability, CRs propagating in the interstellar medium scatter on self-excited Alfvén waves and couple to the gas. When the wave growth due to the streaming instability is inhibited by some damping process, such as turbulent damping, the coupling of CRs to the gas is weaker and their effective propagation speed faster than the Alfvén speed. Alternatively, CRs could scatter from “extrinsic turbulence” that is driven by another mechanism. We demonstrate that the presence of moderately super-Alfvénic CR streaming enhances the efficiency of galactic wind driving. Cosmic rays stream away from denser regions near the galactic disk along partially ordered magnetic fields and in the process accelerate more tenuous gas away from the galaxy. For CR acceleration efficiencies broadly consistent with the observational constraints, CRs reduce the galactic star formation rates and significantly aid in launching galactic winds.
PROPELLER EFFECT IN THE TRANSIENT X-RAY PULSAR SMC X-2

Published: January 2017

We report the results of the monitoring campaign of the transient X-ray pulsar SMC X-2 performed with the Swift/XRT telescope over the period of 2015 September–2016 January during the Type II outburst. During this event, the bolometric luminosity of the source ranged from ≃1039 down to several ×1034 erg s−1. Moreover, we discovered its dramatic drop by a factor of more than 100 below the limiting value of

erg s−1, which can be interpreted as a transition to the propeller regime. These measurements make SMC X-2 the sixth pulsating X-ray source where such a transition is observed and allow us to estimate the magnetic field of the neutron star in the system B ≃ 3 × 1012 G, which is in agreement with independent results of the spectral analysis.

Published: January 2017

We present an extensive spectroscopic follow-up campaign of 29 strong lensing (SL) selected galaxy clusters discovered primarily in the Second Red-Sequence Cluster Survey (RCS-2). Our spectroscopic analysis yields redshifts for 52 gravitational arcs present in the core of our galaxy clusters, which correspond to 35 distinct background sources that are clearly distorted by the gravitational potential of these clusters. These lensed galaxies span a wide redshift range of 0.8 ≤ z ≤ 2.9, with a median redshift of z

s
 = 1.8 ± 0.1. We also measure reliable redshifts for 1004 cluster members, allowing us to obtain robust velocity dispersion measurements for 23 of these clusters, which we then use to determine their dynamical masses by using a simulation-based σ
DM − M
200 scaling relation. The redshift and mass ranges covered by our SL sample are 0.22 ≤ z ≤ 1.01 and

, respectively. We analyze and quantify some possible effects that might bias our mass estimates, such as the presence of substructure, the region where cluster members are selected for spectroscopic follow-up, the final number of confirmed members, and line-of-sight effects. We find that 10 clusters of our sample with N
mem ≳ 20 show signs of dynamical substructure. However, the velocity data of only one system is inconsistent with a uni-modal distribution. We therefore assume that the substructures are only marginal and not of comparable size to the clusters themselves. Consequently, our velocity dispersion and mass estimates can be used as priors for SL mass reconstruction studies and also represent an important step toward a better understanding of the properties of the SL galaxy cluster population.
SILICATE DUST IN ACTIVE GALACTIC NUCLEI
Authors: Xie Yanxia , Li Aigen , Hao Lei
Published: January 2017

The unification theory of active galactic nuclei (AGNs) hypothesizes that all AGNs are surrounded by an anisotropic dust torus and are essentially the same objects but viewed from different angles. However, little is known about the dust that plays a central role in the unification theory. There are suggestions that the AGN dust extinction law appreciably differs from that of the Galaxy. Also, the silicate emission features observed in type 1 AGNs appear anomalous (i.e., their peak wavelengths and widths differ considerably from that of the Galaxy). In this work, we explore the dust properties of 147 AGNs of various types at redshifts

, with special attention paid to 93 AGNs that exhibit the 9.7 and 18 μm silicate emission features. We model their silicate emission spectra obtained with the Infrared Spectrograph aboard the Spitzer Space Telescope. We find that 60/93 of the observed spectra can be well explained with “astronomical silicate,” while the remaining sources favor amorphous olivine or pyroxene. Most notably, all sources require the dust to be micron-sized (with a typical size of ∼1.5 ± 0.1 μm), much larger than submicron-sized Galactic interstellar grains, implying a flat or “gray” extinction law for AGNs. We also find that, while the 9.7 μm emission feature arises predominantly from warm silicate dust of temperature T ∼ 270 K, the ∼5–8 μm continuum emission is mostly from carbon dust of T ∼ 640 K. Finally, the correlations between the dust properties (e.g., mass, temperature) and the AGN properties (e.g., luminosity, black hole mass) have also been investigated.

We present a multi-wavelength photometric catalog in the COSMOS field as part of the observations by the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. The catalog is based on Hubble Space Telescope Wide Field Camera 3 (HST/WFC3) and Advanced Camera for Surveys observations of the COSMOS field (centered at R.A.:

, Decl.:

). The final catalog has 38671 sources with photometric data in 42 bands from UV to the infrared (

). This includes broadband photometry from HST, CFHT, Subaru, the Visible and Infrared Survey Telescope for Astronomy, and Spitzer Space Telescope in the visible, near-infrared, and infrared bands along with intermediate- and narrowband photometry from Subaru and medium-band data from Mayall NEWFIRM. Source detection was conducted in the WFC3 F160W band (at 1.6 μm) and photometry is generated using the Template FITting algorithm. We further present a catalog of the physical properties of sources as identified in the HST F160W band and measured from the multi-band photometry by fitting the observed spectral energy distributions of sources against templates.
Salix transect of Europe: structured genetic variation and isolation-by-distance in the nettle psyllid, Trioza urticae (Psylloidea, Hemiptera), from Greece to Arctic Norway
Authors: Wonglersak Rungtip , Cronk Quentin , Percy Diana
Published: January 2017

The common nettle (Urtica dioica L.) is co-associated with willows (Salix spp.) in riparian habitats across Europe. We sampled the widespread nettle psyllid, Trioza urticae (Linné, 1758), from Urtica in willow habitats on a megatransect of Europe from the Aegean to the Arctic Ocean. The aim of this study was to use an unusually widespread insect to assess the influence of geographic distances and natural geographic barriers on patterns of genetic variation and haplotype distribution.

Phylogeographic analysis using DNA sequences of two mtDNA regions, COI and cytB, shows that T. urticae specimens are organized into four regional groups (southern, central, northern and arctic). These groups are supported by both phylogenetic analysis (four geographically-based clades) and network analysis (four major haplotype groups). The boundary between southern and central groups corresponds to the Carpathian Mountains and the boundary between the central and northern groups corresponds to the Gulf of Finland. Overall these groups form a latitudinal cline in genetic diversity, which decreases with increasing latitude.

Quelles peuvent être les actions à mener par les directions des ressources humaines afin de répondre efficacement au défi de la création des compétences collectives ? Depuis que les nouveaux modèles stratégiques ont recentré la réflexion vers l’organisation interne des entreprises, la création et la gestion de compétences clés sont ainsi devenues une priorité afin de créer et conserver un avantage concurrentiel durable. Pour la fonction contingente des RH, coexiste donc la question des compétences individuelles avec celles des compétences collectives et de leur articulation avec la stratégie d’entreprise. Ceci étant, la Gestion des Ressources Humaines est-elle assez outillée face à ce concept, plus complexe mais indispensable dans l’économie du savoir d’aujourd’hui ? Egalement, comment la RH peut-elle s’imposer comme un réel partenaire stratégique de la direction et l’accompagner sur ce terrain ?

Le moi inconscient, altéré lui-même par le sexual de mort, du fait de l’intromission de messages intraduisibles pour la psyché des patients, se révèle pourtant capable de transfor-mer ce sexual de mort en sexual de vie. Il aura besoin pour ce faire de la rencontre avec une analyste en position matricielle, fonctionnant en tiers matriciel. Il s’agira du fait de l’analyste et de la séduction éthique de la situation analytique, de faire advenir un lieu pour ce qui n’en avait pas rencontré. Psyché apparaît dans toute sa complexité et avec elle, celle d’une topique pre-nant particulièrement en compte la fluidité du sexual de mort comme celui de vie.
L’érogénéité : la batterie du moi
Authors: Gauthier Martin
Published: January 2017

Dans la perspective d’une nouvelle épigenèse depuis les avancées freudiennes après 1920, l’érogénéité s’inscrit dans la liaison de l’excitation brute, aux ¬fondements du corps érogène et du moi. Elle s’avère un construit, le fruit d’un ¬travail d’¬élaboration de la pulsion et du moi, véritable batterie du moi issue du giron relationnel. Elle demeure cependant toujours ac-tuelle, dans l’interface entre sujet et objet. Le dispositif analytique classique se révèle être au service de la modulation de l’intensité érogène. Érogénéité, transitionnalité et symbolisation évoluent ensemble pour la croissance de l’arbre moïque et de ses racines. En revanche, au-delà d’un seuil ¬critique, quand le fonctionnement traumatique prévaut, le clivage traduit l’envers de la transitionnalité.
Racines corporelles du moi, érogénéisation : l’impact de l’objet sur le corps du sujet et ses répercussions sur son érogénéisation
Authors: Labbé Françoise
Published: January 2017

Nous examinons l’incidence de la qualité de la réponse de l’objet sur le développement du sujet et l’érogénéisation du corps. Les racines corporelles du moi font référence aux théories de G. Haag sur les premières identifications corporelles. Le rôle de l’objet dans l’organisation des traces mnésiques et de la symbolisation s’appuie sur la théorie de R. Roussillon. C. Dejours montre également les répercussions de la qualité des réponses des objets parentaux vis-à-vis des sollicitations du sujet.
Incidents de séance et pensées incidentes
Authors: Zilkha Nathalie
Published: January 2017

Certaines cures sont davantage marquées que d’autres par l’élaboration d’incidents de séance, parfois minimes. Il peut toutefois être difficile de différencier ce qui tient du moi processuel inconscient et ce qui tient du retour du refoulé, d’autant que l’incident de séance exerce souvent un effet attracteur sur les représentations et fantasmes refoulés. Une séance fortement marquée par un agir contre-transférentiel et son élaboration par l’analysant, récit assez détaillé que propose Freud dans sa XXXe conférence, Rêve et occultisme, servira d’illustration à ce propos.
Le moi inconscient sous l’emprise de l’objet
Authors: A. Sparer Ellen
Published: January 2017

La deuxième topique a amené Freud à introduire un « troisième » inconscient, celui du moi, d’emblée uni avec le ça et influencé par ce qu’il a vécu. L’auteur souligne la confluence entre le moi idéal et le moi inconscient, qui comporte une identification primaire avec l’objet primaire. Cette identification peut devenir aliénante si le moi naissant se trouve investi dans une « masse à deux » amenant à une identification avec le moi idéal plutôt qu’avec le surmoi.
Les identifications aliénantes dans la cure
Authors: Hadjiyanni-Stephanatou Tessa
Published: January 2017

Le concept d’identification à l’agresseur peut s’avérer précieux pour penser la pro-blématique des identifications aliénantes et plus particulièrement dans la cure. À ¬partir d’une séquence clinique il est montré, comment un passage par l’acte de la patiente dans le cadre d’une identification à l’agresseur de type Anna Freud – ¬mouvement ¬identificatoire qui permet au sujet d’exprimer sa haine – permet un dégagement de l’identification narcissique à l’agresseur de type ferenczien, et ainsi constitue un début de mise en représentation de la séparation dans le transfert.
L’éducation populaire
Authors: Besse Laurent , Chateigner Frédéric , Ihaddadene Florence
Published: January 2017

Catégorie récemment très discutée mais impossible à définir de façon consensuelle, l’éducation populaire est ici approchée sous trois angles disciplinaires. L’histoire sociale et culturelle de l’éducation populaire a réussi à se détacher de la mythologie militante, au risque de se replier vers les seules questions de jeunesse. La sociologie critique du travail associatif s’avère particulièrement éclairante pour un secteur de la vie associative nettement politisé, et où les tensions associées au statut de militant-salarié sont particulièrement discutées. L’approche par la science politique des références publiques récentes à l’éducation populaire en France dessine une nouvelle définition, encore vague, de l’éducation populaire comme éducation politique des adultes. On analyse pour finir les imports étrangers dans ces discours. Ces chantiers de recherche convergent vers la nécessité d’une étude empirique des pratiques.
La expansión urbana y sus impactos sobre el clima y la sociedad de la ciudad de Bahía Blanca, Argentina
Authors: Ferrelli Federico , Luján Bustos María , Cintia Piccolo María
Published: January 2017

El objetivo de este trabajo fue analizar los efectos de la expansión urbana de Bahía Blanca sobre el microclima y la biomasa considerando la percepción de sus habitantes. Se utilizaron imágenes satelitales LANDSAT para el período 1986-2014. Se estimó el área urbana, la temperatura y la biomasa. Se analizaron datos meteorológicos de temperatura, humedad relativa y velocidades máximas de viento provistos por el Servicio Meteorológico Nacional (Argentina). El crecimiento de la ciudad redujo la biomasa. La TST disminuyó 0.6 ºC debido al aumento de las sombras generadas por los edificios, a la densidad de los mismos y a la capacidad calorífica de los materiales que los componen, entre otros factores. La temperatura del aire se incrementó 0.7 ºC y la humedad relativa disminuyó un 6%. La opinión de los habitantes coincidió con los datos meteorológicos analizados. La consulta a los actores sociales generó información útil para orientar la planificación de la ciudad, las políticas públicas y la toma de decisiones para mejorar la calidad de vida de los habitantes.
Incremento de los riesgos geomorfológicos en el espacio urbano de Sarajevo como consecuencia del proceso de suburbanización y las políticas de neoliberalización
Authors: Martín-Díaz Jordi , Nofre Jordi , Oliva Marc , Palma Pedro
Published: January 2017

El pasado mes de mayo de 2014, las precipitaciones asociadas al profundo sistema de bajas presiones Tamara provocaron severas inundaciones y numerosos deslizamientos de tierra que afectaron a vastas áreas de la región balcánica occidental y central, alcanzando también la ciudad de Sarajevo (Bosnia y Herzegovina). En este episodio quedaron evidenciados los riesgos hidrológicos y geomorfológicos que afectan actualmente a un número significativo de áreas urbanas y suburbanas construidas en la capital bosnia desde el fin de la guerra. A partir de un trabajo observacional y etnográfico realizado entre los años 2010 y 2013, y con apoyo operacional de los Sistemas de Información Geográfica, este artículo tiene como objetivo analizar la creciente insostenibilidad urbana de la ciudad de Sarajevo, producida tanto por una densificación del fondo de valle en áreas inundables así como el proceso de suburbanización que ha ve nido produciéndose principalmente en las laderas de los macizos que abrigan la ciudad. Estos procesos son, respectivamente, resultado de la implementación de las políticas de liberalización económica y de la necesidad por parte de las personas refugiadas en Sarajevo de estabilizar su situación en la ciudad tras el conflicto bélico.
El lugar del paisaje y su valoración en la geografía española moderna: de Rafael Torres Campos a Manuel de Terán
Authors: Ortega Cantero Nicolás
Published: January 2017

Este artículo está dedicado a estudiar la trayectoria seguida en España por el paisajismo geográfico moderno fundado por Humboldt. Se consideran sucesivamente la entrada en España de ese paisajismo, a través de la obra de Francisco Giner, y su posterior desarrollo en la obra de geógrafos y naturalistas directamente conectados con la doble tradición paisajística humboldtiana y gineriana, hasta llegar a la visión del paisaje de Manuel de Terán, que constituye el eslabón final de esa trayectoria.
Evaluación de la equidad del servicio de transporte público: El caso de Palma de Mallorca
Authors: Ruiz Maurici , Seguí Pons Joana Maria , Mateu Lladó Jaume , Martínez Reynés Maria Rosa
Published: January 2017

La planificación sostenible del transporte público requiere la consideración de la equidad territorial y social. El análisis de la equidad precisa de un profundo conocimiento del servicio así como de las características territoriales y sociales dónde se implanta. En este artículo se propone un método simplificado para el análisis de la equidad del sistema de autobuses públicos, aplicado a la ciudad de Palma. El nivel de servicio se calcula a partir del análisis territorial de la oferta, y se contrasta con la población existente y con un índice multidimensional de necesidad social de transporte público, dando lugar a la equidad horizontal y vertical, respectivamente. Posteriormente, se verifica la equidad global del servicio con el apoyo de la curva de Lorenz y del coeficiente GINI. Finalmente, se realiza un análisis de sensibilidad a través de la frecuencia de las rutas de autobús en relación a la equidad social del servicio.
Consolidación y secuela de un error: el precioso caso de las piedras preciosas prasma y plasma
Authors: Varela Villafranca Diego
Published: January 2017

En este artículo estudiamos el origen del español prasma ‘ágata de color verde oscuro’, para lo cual hacemos un recorrido por los testimonios de prasma en nuestro idioma, analizamos sus paralelos en otras lenguas europeas —con especial atención para el francés antiguo prasme— y cotejamos las propuestas etimológicas que ha habido hasta la fecha. A la vista de los datos, pretendemos demostrar que, en última instancia, prasma procede por un error de lectura del latín tardío PRAS/NUS o PRAS/NA. Completamos el estudio adentrándonos en la historia de plasma, variante más reciente de prasma.
Liberté de presse écrite au Maroc : L’évolution au regard de l’évaluation
Authors: Naimi Mohamed
Published: January 2017

Le présent article vise à examiner la situation de la liberté de presse au Maroc et son évolution depuis 2011 au regard de son évaluation aux niveaux international et national. Alors que les ONG internationales spécialisées dans le domaine, notamment Freedom House (FH) et Reporters sans frontières (RSF) accablent le Maroc, les instances marocaines officielles tiennent un discours plutôt apologétique et affichent par réflexe l’image d’une presse libre. Pour approcher la situation réelle de la liberté de presse au Maroc, il nous semble intéressant de saisir les différences d’objectifs et de méthodes de ces évaluations, avant de les confronter aux pratiques et ressenti des principaux intéressés : les journalistes marocains. Évaluer l’évolution de cette liberté revient donc à examiner tour à tour, et à la lumière de l’enquête menée auprès des journalistes, les deux systèmes d’évaluation, celui établi par les instances internationales et celui fourni par les autorités marocaines.

Authors: Merah Aissa
Published: January 2017

Nous abordons ici la question de l’identité professionnelle des journalistes de la presse en ligne en Algérie. Il s’agit de souligner, dans un premier temps, la pertinence sociale et scientifique du sujet, puis de mobiliser les éléments théoriques qui permettent de comprendre la transition professionnelle des journalistes en ligne et la nature dynamique de leur identité. Après avoir exposé la démarche méthodologique, nous revenons sur le contexte d’émergence de cette presse en Algérie, tout en insistant sur ses caractéristiques en relation avec l’identité professionnelle. L’enquête empirique scrute les profils sociaux et les compétences des web-journalistes, avant de conclure sur les principaux résultats de l’étude.
Role of Bulky Retained Austenite in Austempered Ductile Iron
Authors: Yang Chen , Cui Xi Xi , Zhao Zhen Bo , Hua Gao , Liu Cheng
Published: January 2017

In this investigation, the characteristics of bulky retained austenite in an austempered ductile iron are evaluated in two tempered conditions. which were intially tempered at 200oC for 1h before cooling to room temperature, and then tempered at 350oC for 1h. The result shows that the hardness within retained austenite areas is distributed unevenly with a range from 423 HV to 897 HV, which is attributed to the transformation from austenite to martensite during austempering. Also, the mechanism regarding the quenched marteniste formation is discussed. The poor fatigue resistance of ADI is hypothesized to be due to the amount of austenite transformed to martensite.
Synthesis and Characterization of Thiol- and Carboxyl-Functionalized Mesoporous Silica Nanoparticles
Authors: Wang Wan Xia , Wang Yu , Gong Hua Meng , Sun Hong Hao , Liu Ming Xing
Published: January 2017

The purpose of this article is to synthesize the thiol-and carboxyl-bifunctionalized mesoporous silica nanoparticles (CMS-SH-COOH). CMS-SH-COOH was successfully synthesized by co-condensation and post-grafting methods. Moreover, the particle size and structural properties of CMS-SH-COOH were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and Fourier transform infrared spectroscopy (FT-IR). The obtained results indicated that the CMS-SH-COOH presented a uniform spherical shape with a wormhole arrangement of the mesopores and a relatively narrow paticle distribition. Therefore, the CMS-SH-COOH might be a great potential carrier for the drug delivery system in the future.
