description: Lagrangian Floer theory is one of the main tools of current research in symplectic geometry. In immersed Lagrangian Floer homology, the differential counts rigid holomorphic disks with Lagrangian boundary condition associated with the immersion. We focused on the rigidity condition of holomorphic disks and visualized it as the angle change of the image, applied this result to computations of immersions of S¹ into S². In particular, we computed the immersed Floer homology of (1, 3) and (1, 4)-satellite knots of S¹ using this result and some other techniques, and found a general expression of the Floer homology of (p, q)-satellite knots of S¹.

description: Coevol input files include sequence data, phylogenetic tree files, and text files of traits. Detailed methods about the collection and processing of the dataset are included in the manuscript and in the folder of code ("migration-molecrates-main"). Briefly, mitochondrial gene sequences were generated from samples that we sequenced with low-coverage genome sequencing; phylogenetic trees are from birdtree.org; trait data include per-species body mass estimates from publicly available sources and migration distance estimates from species' range maps; and trait data also include population genetic parameters estimated using population-level datasets of mitochondrial gene sequences (not included here). All mitochondrial gene sequences, including those for population-level analyses, are available on GenBank as described in Table S2 of this manuscript's supplement section.
Single parameter galaxy classification: The Principal Curve through the multi-dimensional space of galaxy properties

description: We propose to describe the variety of galaxies from SDSS by using only one affine parameter. To this aim, we build the Principal Curve (P-curve) passing through the spine of the data point cloud, considering the eigenspace derived from Principal Component Analysis of morphological, physical and photometric galaxy properties. Thus, galaxies can be labeled, ranked and classified by a single arc length value of the curve, measured at the unique closest projection of the data points on the P-curve. We find that the P-curve has a "W" letter shape with 3 turning points, defining 4 branches that represent distinct galaxy populations. This behavior is controlled mainly by 2 properties, namely u-r and SFR. We further present the variations of several galaxy properties as a function of arc length. Luminosity functions variate from steep Schechter fits at low arc length, to double power law and ending in Log-normal fits at high arc length. Galaxy clustering shows increasing autocorrelation power at large scales as arc length increases. PCA analysis allowed to find peculiar galaxy populations located apart from the main cloud of data points, such as small red galaxies dominated by a disk, of relatively high stellar mass-to-light ratio and surface mass density. The P-curve allows not only dimensionality reduction, but also provides supporting evidence for relevant physical models and scenarios in extragalactic astronomy: 1) Evidence for the hierarchical merging scenario in the formation of a selected group of red massive galaxies. These galaxies present a log-normal r-band luminosity function, which might arise from multiplicative processes involved in this scenario. 2) Connection between the onset of AGN activity and star formation quenching, which appears in green galaxies when transitioning from blue to red populations.

description: In this proceedings, we report measurements of the third harmonic coefficient of the azimuthal anisotropy, $v_{3}$, known as triangular flow. The analysis is for charged particles near midrapidity in Au+Au collisions at $\sqrt {s_{NN}} $ = 200 GeV, based on data from the STAR experiment at the Relativistic Heavy Ion Collider. Triangular flow as a function of centrality, pseudorapidity and transverse momentum are reported using various methods, including a study of the signal for particle pairs as a function of their pseudorapidity separation. Results are compared with other experiments and model predictions.

description: Two classical results characterizing regularity of a convergence space in terms of continuous extensions of maps on one hand, and in terms of continuity of limits for the continuous convergence on the other, are extended to convergence-approach spaces. Characterizations are obtained for two alternative extensions of regularity to convergence-approach spaces: regularity and strong regularity. The results improve upon what is known even in the convergence case. On the way, a new notion of strictness for convergence-approach spaces is introduced.

description: With robot utilization reaching $300 million in the hospitality industry, this paper aims to examine the difference in customer response between two types of anthropomorphic features (cute vs. cool) of service robots. Four scenario-based experiments (2 [robot appearances: cute vs. cool] x 2 [customer–company relationship norms: communal vs. exchange]) were employed in two different contexts (Study 1: service successful and Study 2: failure). The results showed that cute robots elicit higher customer satisfaction, repatronage intention, and willingness to spread positive word of mouth when customers were in a communal relationship with a company. The difference was significant only in the situation in which the robots’ service failed. This study offers the industry guidelines to decide on robot design according to their relationship with the customer and develops the topic of anthropomorphism in robots in that it looked into the different traits within anthropomorphism rather than human likeness versus nonhuman likeness.

description: In the framework of the first Born approximation, we present a semirelativistic theoretical study of the inelastic excitation ($1s_{1/2}\longrightarrow 2s_{1/2}$) of hydrogen atom by electronic impact. The incident and scattered electrons are described by a free Dirac spinor and the hydrogen atom target is described by the Darwin wave function. Relativistic and spin effects are examined in the relativistic regime. A detailed study has been devoted to the nonrelativistic regime as well as the moderate relativistic regime. Some aspects of this dependence as well as the dynamic behavior of the DCS in the relativistic regime have been addressed.

Possible indication for non-zero neutrino mass and additional neutrino species from cosmological observations

description: The constraints on total neutrino mass and effective number of neutrino species based on CMB anisotropy power spectrum, Hubble constant, baryon acoustic oscillations and galaxy cluster mass function data are presented. It is shown that the discrepancies between various cosmological data in Hubble constant and density fluctuation amplitude, measured in standard LCDM cosmological model, can be eliminated if more than standard effective number of neutrino species and non-zero total neutrino mass are considered. This extension of LCDM model appears to be \approx 3 σ significant when all cosmological data are used. The model with approximately one additional neutrino type, N_eff \approx 4, and with non-zero total neutrino mass, \approx 0.5 eV, provide the best fit to the data. In the model with only one massive neutrino the upper limits on neutrino mass are slightly relaxed. It is shown that these deviations from LCDM model appear mainly due to the usage of recent data on the observations of baryon acoustic oscillations. Larger than standard number of neutrino species is measured mainly due to the comparison of the BAO data with direct measurements of Hubble constant, which was already noticed earlier. As it is shown below, the data on galaxy cluster mass function in this case give the measurement of non-zero neutrino mass.

Toroidal, compression, and vortical dipole strengths in $^{144-154}$Sm: Skyrme-RPA exploration of deformation effect

description: A comparative analysis of toroidal, compressional and vortical dipole strengths in the spherical $^{144}$Sm and the deformed $^{154}$Sm is performed within the random-phase-approximation using a set of different Skyrme forces. Isoscalar (T=0), isovector (T=1), and electromagnetic excitation channels are considered. The role of the nuclear convection $j_{\text{con}}$ and magnetization $j_{\text{mag}}$ currents is inspected. It is shown that the deformation leads to an appreciable redistribution of the strengths and causes a spectacular deformation splitting (exceeding 5 MeV) of the isoscalar compressional mode. In $^{154}$Sm, the $μ$=0 and $μ$=1 branches of the mode form well separated resonances. When stepping from $^{144}$Sm to $^{154}$Sm, we observe an increase of the toroidal, compression and vortical contributions in the low-energy region (often called pygmy resonance). The strength in this region seems to be an overlap of various excitation modes. The energy centroids of the strengths depend significantly on the isoscalar effective mass $m_0$. Skyrme forces with a large $m_0$ (typically $m_0/m \approx 0.8 - 1$) seem to be more suitable for description of experimental data for the isoscalar giant dipole resonance.

The model may also have an AdS$_2\times R^d$ vacuum solution. By making use of our results, one may wonder that within the context of HL gravity the Lifshitz fixed point might be treated as a CFT deformed by the time component of a vector operator.

description: Recent measurements of the abundance of AGN with low-luminosities (L_X< 10^44 erg/s in the 2-10 keV energy band) at high redshifts z>4 provide a serious challenge for Cold Dark Matter (CDM) models based on interaction-driven fueling of AGN. Using a semi-analytic model of galaxy formation we investigate how such observations fit in a Warm Dark Matter (WDM) scenario of galaxy formation, and compare the results with those obtained in the standard CDM scenario with different efficiencies for the stellar feedback. Taking on our previous exploration of galaxy formation in WDM cosmology, we assume as a reference case a spectrum which is suppressed - compared to the standard CDM case - below a cut-off scale ~ 0.2$ Mpc corresponding (for thermal relic WDM particles) to a mass m_X=0.75 keV. We run our fiducial semi-analytic model with such a WDM spectrum to derive AGN luminosity functions from z~6 to the present over a wide range of luminosities (10^43< L_X/erg/s < 10^46 in the 2-10 keV X-ray band), to compare with recent observations and with the results in the CDM case. When compared with the standard CDM case, the luminosity distributions we obtain assuming a WDM spectrum are characterized by a similar behaviour at low redshift, and by a flatter slope at faint magnitudes for z>3, which provide an excellent fit to present observations. We discuss how such a result compares with CDM models with maximized feedback efficiency, and how future deep AGN surveys will allow for a better discrimination between feedback and cosmological effects on the evolution of AGN in interaction-driven models for AGN fueling.

description: Η εργασία αποτελεί μια βιβλιογραφική ανασκόπηση σχετικά με τις αρχές του μάνατζμεντ στις ελληνικές μικρομεσαίες επιχειρήσεις. Οι μικρομεσαίες επιχειρήσεις αποτελούν έναν από τους βασικούς πυλώνες της ελληνικής οικονομίας καθώς ο αριθμός των απασχολούντων σε αυτές είναι πολύ μεγάλος και σημαντικός. Ειδικά στην Ελλάδα υπολογίζεται ότι ο αριθμός των μικρομεσαίων επιχειρήσεων αγγίζει το 99% του συνόλου των επιχειρήσεων. Παρ΄ όλα αυτά, είναι σημαντική η έλλειψη στρατηγικών σχεδιασμών και μάνατζμεντ στις περισσότερες των ελληνικών μικρομεσαίων επιχειρήσεων με αποτέλεσμα να μην μπορούν να ανταποκριθούν στις απαιτήσεις της σύγχρονης αγοράς. Η μη σωστή οργάνωση των δραστηριοτήτων των εταιρειών βάσει των αρχών του μάνατζμεντ και η ελλιπής αντιμετώπιση των προβλημάτων που προκύπτουν  δυσκολεύει την προσαρμογή των επιχειρήσεων και τη βιωσιμότητά τους. Σκοπός της εργασίας είναι η ανάλυση της έννοιας του μάνατζμεντ αλλά και επιμέρους στοιχείων που είναι πολύ σημαντικά για την οργάνωση και λειτουργία μιας μικρομεσαίας επιχείρησης. Ουσιαστικά, αναλύεται ένα σύγχρονο πρότυπο διοίκησης και οργάνωσης, η τμηματοποίηση αλλά και τα χαρακτηριστικά που πρέπει να έχουν τα διοικητικά στελέχη μιας μικρομεσαίας επιχείρησης με βάση την ελληνική και διεθνή βιβλιογραφία.
description: The thesis is a bibliographic review, based on Greek and international literature, of the management principles in Greek small and medium-sized enterprises. Small and medium-sized enterprises are one of the main pillars of the Greek economy because of the number of employees in them is significant. Especially in Greece it is estimated that the number of small and medium-sized enterprises is 99% of all enterprises. However, the lack of strategic planning and management in most of the Greek small and medium-sized enterprises is important, as a result of which they can not meet the demands of the modern market. Incorrect organization of company operations based on management principles and inadequate coping with the problems that arise makes it difficult to adapt to business and their viability. The purpose of the thesis is to analyze the concept of management as well as individual elements that are very important for the organization and operation of a small and medium-sized enterprise. In conclusion, a modern model of administration and organization, the segmentation and the characteristics of the management of a small and medium-sized enterprise are analyzed.

description: This report presents azimuthal dependent and polarisation dependent x-ray resonant magnetic scattering at the Ir L3 edge for the bilayered iridate compound, Sr3Ir2O7. Two magnetic wave vectors, k1=(1/2,1/2,0) and k2=(1/2,-1/2,0), result in domains of two symmetry-related G-type antiferromagnetic structures, noted A and B, respectively. These domains are approximately 0.02 mm^2 and are independent of the thermal history. An understanding of this key aspect of the magnetism is necessary for an overall picture of the magnetic behaviour in this compound. Azimuthal and polarisation dependence of magnetic reflections, relating to both magnetic wave vectors, show that the Ir magnetic moments in the bilayer compound are oriented along the c axis. This contrasts with single layer Sr2IrO4 where the moments are confined to the ab plane.

description: In Gabon, revenues generated by thriving mineral, petroleum, and timber exports have produced a modern urban sector which contrasts with a countryside almost devoid of infrastructure and drained of people, especially young people. The result is that Gabon has the second highest per capita income in Africa and probably the least developed agricultural sector. This structure poses problems for the Government of Gabon, which is trying to develop large-scale, mechanized production in capital-intensive projects in the face of cheaper food imports, and at the same time attempting to launch a rural development program to overcome twenty years of neglect.

description: DNA methyltransferase 2 (DNMT2) was renamed as tRNA aspartic acid methyltransferase 1 (TRDMT1) by catalyzing the methylation of tRNAAsp anti-codon loop C38. The development of sequencing of nucleic acids and protein detection techniques have prompted the demonstration that TRDMT1 mediated tRNA modification affects protein synthesis efficiency. This process affects the growth and development of animals. The DNA of 224 Qinchuan cattles aged 2–4 years old was collected in this experiment. The genetic variations of TRDMT1 exon and some intron regions were detected by mixed pool sequencing technology. qRT-PCR and Western Blot were used to detect the expression levels of mRNA and protein produced with the combination of different genetic variant loci. Three haplotypes were detected and the distribution ratios were different. Muscle tissue mRNA and protein testing showed that there were differences in mRNA expression levels among different genotypes (P < 0.05) and the protein expression levels between different genotypes show the same trend as mRNA. This study provides potential molecular materials for the improvement of Qinchuan cattle reproductivity and provides theoretical support for studying the effects of livestock TRDMT1 on animal growth and development.

description: The mission of the PlasmaPy project is to foster the creation of a fully open source software ecosystem for plasma science. An essential part of that mission is to create open access educational resources. For example, PlasmaPy's example gallery contains Jupyter notebooks that cover topics such as plasma parameters in the solar atmosphere and Earth's magnetosphere, particle drifts, plasma wave dispersion relationships, Langmuir probe analysis, Thomson scattering, and synthetic charged particle radiography. These notebooks can be downloaded, modified, and re-executed. Several of these notebooks have been adapted into interactive tutorials for use at summer schools, conferences, and Plasma Hack Week. We invite the broader plasma community to contribute notebooks to PlasmaPy's gallery, and to use the example gallery in plasma courses.

title: University academic staff members as gatekeepers of mental health for graduate students
Creators: name: Punjabi, Ashwini

description: Mental health challenges are six times higher in graduate students compared to the general population. Despite the strikingly high numbers, very few students seek professional help. This study aims to determine if academic staff members (ASMs) are potential gatekeepers of mental health for graduate students, as they are well-positioned to offer an initial point of contact to connect students in distress to professional help sources. A total of 125 ASMs at a large teaching and research university in Canada completed an anonymous online survey that measured multiple factors associated with being a mental health gatekeeper, such as mental health literacy, preparedness and self-efficacy, using the Mental Health Literacy Scale (MHLS), Gatekeeper Behavior Scale (GBS) and Gatekeeper Self-Efficacy Scale (GKSES), respectively, along with demographic and professional information. Open-ended questions on types of support and/or training required were also included to understand what changes need to be adopted for ASMs’ work organization upon taking the role of a gatekeeper. The data were analyzed using descriptive and inferential statistics, including one-way ANOVA, to compare differences among genders, academic disciplines and academic ranks. ASMs demonstrated higher mean scores in all three outcome measures: mental health literacy (M=123, SD=23), gatekeeper behavior scale (M=62, SD=21) and gatekeeper self-efficacy scale (M=37, SD=14) as compared to previous studies. There was a significant difference in mental health literacy among academic disciplines (F(2,120)=7.8, p=0.001) and academic ranks (F(3,121)=3.9, p=0.01). The findings also indicated significant differences in both preparedness (F(2,120)=5.9, p=0.003) and self-efficacy (F(2,120)=9.2, p=0.000) between academic disciplines. No difference was found between genders in any of the three outcome measures. The participants recognized the need to support students but did not feel adequately prepared to recognize mental health challenges or feel knowledgeable about how to support students. ASMs in this study revealed the need for appropriate gatekeeper training and addressed effective strategies, coping tools, and resources that the university can implement to support them. Thus, ASMs can be potential gatekeepers of mental health for graduate students if they can receive appropriate training and support from the university to help their graduate students effectively when needed.

Surface Terms of Quartic Quasitopological Gravity and Thermodynamics of Nonlinear Charged Rotating Black Branes

description: As in the case of Einstein or Lovelock gravity, the action of quartic quasitopological gravity has not a well-defined variational principle. In this paper, we first introduce a surface term that makes the variation of quartic quasitopological gravity well defined. Second, we present the static charged solutions of quartic quasitopological gravity in the presence of a non linear electromagnetic field. One of the branch of these solutions presents a black brane with one or two horizons or a naked singularity depending on the charge and mass of the solution. The thermodynamic of these black branes are investigated through the use of the Gibbs free energy. In order to do this, we calculate the finite action by use of the counterterm method inspired by AdS/CFT correspondence. Introducing a Smarr-type formula, we also show that the conserved and thermodynamics quantities of these solutions satisfy the first law of thermodynamics. Finally, we present the charged rotating black branes in $(n+1)$ dimensions with $k\leq [n/2]$ rotation parameters and investigate their thermodynamics.

description: We present Spitzer/IRAC 4.5-micron transit photometry of GJ3470b, a Neptune-size planet orbiting a M1.5 dwarf star with a 3.3-day period recently discovered in the course of the HARPS M-dwarf survey. We refine the stellar parameters by employing purely empirical mass-luminosity and surface brightness relations constrained by our updated value for the mean stellar density, and additional information from new near-infrared spectroscopic observations. We derive a stellar mass of M_star = 0.539+0.047-0.043 M_sun and a radius of R_star = 0.568+0.037-0.031 R_sun. We determine the host star of GJ3470b to be metal-rich, with a metallicity of [Fe/H] = +0.20 +/- 0.10 and an effective temperature of Teff = 3600 +/- 100 K. The revised stellar parameters yield a planetary radius R_pl = 4.83+0.22-0.21 R_Earth that is 13 percent larger than the value previously reported in the literature. We find a planetary mass M_pl = 13.9+1.5-1.4 M_Earth that translates to a very low planetary density, rho_pl = 0.72+0.13-0.12 gcm-3, which is 33% smaller than the original value. With a mean density half of that of GJ436b, GJ3470b is an example of a very low-density low-mass planet, similar to Kepler-11d, Kepler-11e, and Kepler-18c but orbiting a much brighter nearby star that is more conducive to follow-up studies.

description: Determinations of the strong coupling strength, $α_s$, are summarised and a new world average value of $α_s (M_Z)$ is determined, using a new method of pre-averaging results within classes of measurements like hadronic $τ$ decays, deep inelastic scattering processes, lattice calculations, electron-positron annihilation processes and electro-weak precision fits. The overall result is $$α_s (M_Z) = 0.1184 \pm 0.0007,$$ unchanged from the value obtained in 2009. This presentation is an excerpt from the QCD review section of the 2012 Review of Particle Physics (RPP) of the Particle Data Group.

description: Motivated by our subfactor generalization of Wall's conjecture, in this paper we determine all intermediate subfactors for conformal subnets corresponding to four infinite series of conformal inclusions, and as a consequence we verify that these series of subfactors verify our conjecture. Our results can be stated in the framework of Vertex Operator Algebras. We also verify our conjecture for Jones-Wassermann subfactors from representations of Loop groups extending our earlier results.
