This research examines the effects of profitability, systematic risk, leverage and earnings persistence on Earnings Response Coefficient (ERC) in companies listed in LQ45 at the Indonesia Stock Exchange (IDX). The objects of this research are companies that are consistently listed in LQ45 in the year of 2015-2017. This study uses panel data regression analysis using the software, Eviews. The empirical results of this research showed that systematic risk and earnings persistence has a significantly negative effect on ERC, leverage has a significantly positive effect on ERC, while profitability does not have an effect on ERC. The results of the research show that the factors of systematic risk, leverage and earnings persistence owned by the company have an effect on investment decisions made by investors.
Phrasal verbs or words? Towards the analysis of gesture and prosody as indexes of lexicalisation

The classification of languages according to the strategy adopted for the expression of Motion Events (Talmy, 1985, 2001) is to be considered as most interesting where it concerns gesture studies. This classification was adopted in a number of gesture studies which revealed that the iconics tend to synchronize with the satellite in satellite-framed languages, and with the verb in verb-framed languages (McNeill, 1992). Also, a further study showed that L2 learners, whose mother language is verb-framed , tend to synchronize their gestures with the verb when speaking English, which is satellite-framed (Stam, 1999). Nevertheless, a recent research on Dutch speakers learning English as an L2 (Kellerman & Hoof, 2003) provides evidence that even in the case of a satellite-framed mother language, speakers tend to synchronize the gesture with the verb when speaking a satellite-framed second language. A possible solution to this apparent discrepancy may perhaps be found if one hypothesizes different levels of lexicalisation for phrasal verbs in different satellite-framed languages. I propose a three-level model for the prediction of lexicalisation. Such a model has been applied to Italian, which, although a Romance language, may show several satellite-framed constructions in colloquial use.
ARRAKIS: atlas of resonance rings as known in the S4G

Context. Resonance rings and pseudorings (here collectively called rings) are thought to be related to the gathering of material near dynamical resonances caused by non-axisymmetries in galaxy discs. This means that they are the result of secular evolution processes that redistribute material and angular momentum in discs. Studying them may give clues on the formation and growth of bars and other disc non-axisymmetries. Aims. Our aims are to produce a catalogue and an atlas of the rings detected in the Spitzer Survey of Stellar Structure in Galaxies (S(4)G) and to conduct a statistical study of the data in the catalogue. Methods. We traced the contours of rings previously identified and fitted them with ellipses. We found the orientation of bars by studying the galaxy ellipse fits from the S(4)G pipeline 4. We used the galaxy orientation data obtained by the S4G pipeline 4 to obtain intrinsic ellipticities and orientations of rings and the bars. Results. ARRAKIS contains data on 724 ringed galaxies in the S(4)G. The frequency of resonance rings in the S4G is of 16 +/- 1% and 35 +/- 1% for outer and inner features, respectively. Outer rings are mostly found in Hubble stages - 1 \textless= T \textless= 4. Inner rings are found in a broad distribution that covers the range - 1 \textless= T \textless= 7. We confirm that outer rings have two preferred orientations, namely parallel and perpendicular to the bar. We confirm a tendency for inner rings to be oriented parallel to the bar, but we report the existence of a significant fraction (maybe as large as 50%) of inner features that have random orientations with respect to the bar. These misaligned inner rings are mostly found in late-type galaxies (T \textgreater= 4). We find that the fraction of barred galaxies hosting outer (inner) rings is similar to 1.7 times (similar to 1.3 times) that in unbarred galaxies. Conclusions. We confirm several results from previous surveys as well as predictions from simulations of resonant rings and/or from manifold flux tube theory. We report that a significant fraction of inner rings in late-type galaxies have a random orientation with respect to the bar. This may be caused by spiral modes that are decoupled from the bar and dominate the Fourier amplitude spectrum at the radius of the inner ring. The fact that rings are only mildly favoured by bars suggests that those in unbarred galaxies either formed because of weak departures from the axisymmetry of the galactic potential or that they are born because of bars that were destroyed after the ring formation.
The rotation of field stars from CoRoT data

We present period measurements of a large sample of field stars in the solar neighbourhood, observed by the COnvection ROtation and planetary Transits (CoRoT) satellite in two different directions of the Galaxy. The presence of a period was detected using the Lomb–Scargle normalized periodogram technique and the autocorrelation analysis. The assessment of the results has been performed through a consistency verification supported by the folded light-curve analysis. The data analysis procedure has discarded a non-negligible fraction of light curves due to instrumental artefacts; however, it has allowed us to identify pulsators and binaries among a large number of field stars. We measure a wide range of periods, from 0.25 to 100 d, most of which are rotation periods. The final catalogue includes 1978 periods, with 1727 of them identified as rotational periods, 169 as pulsations and 82 as orbital periods of binary systems. Our sample suffers from selection biases not easily corrected for; thus, we do not use the distribution of rotation periods to derive the age distribution of the main-sequence population. Nevertheless, using rotation as a proxy for age, we can identify a sample of young stars (≤600 Myr) that will constitute a valuable sample, supported by further spectroscopic observations, to study the recent star formation history in the solar neighbourhood.
Serum vitamin D receptor and ﬁ broblast growth factor-23 levels in postmenopausal primary knee osteoarthritis patients

Objectives: The role of vitamin D in primary osteoarthritis (OA) has not been clarified yet. vitamin D receptor (VDR) and fibroblast growth factor-23 (FGF-23) are proteins that play an important role in the metabolism of vitamin D. In this preliminary study, we aimed to examine serum 25-(OH) vitamin D 3 , VDR, and FGF-23 levels in primary knee OA patients. Methods: This study includes 60 post-menopausal women who were enrolled into two groups with primary knee OA (n=30, age range between 59.6 ± 5.7 years) and control (n=30, age range between 61.7 ± 6.3 years). Serum levels of 25-(OH) vitamin D 3 were measured by chemiluminescence and serum VDR, and FGF-23 were measured by enzyme-linked immunosorbent assay methods. Results: In knee OA group, serum levels of 25-(OH) vitamin D 3 were signi ﬁ cantly lower (p=0.033), and serum VDR and FGF-23 levels were signi ﬁ cantly higher than those of the control group respectively (p=0.000 and p=0.006). Also, FGF-23 levels showed correlations with 25-(OH) vitamin D 3 , VDR, and calcium levels (p<0.05). Conclusions: This is the first study showing a relationship between serum VDR and FGF-23 in knee OA patients. Extensive clinical studies are required to assess the applica-bility of these parameters in clinical practice.
THE FIRST CATALOG OF ACTIVE GALACTIC NUCLEI DETECTED BY THE FERMI LARGE AREA TELESCOPE

We present the first catalog of active galactic nuclei (AGNs) detected by the Large Area Telescope (LAT), corresponding to 11 months of data collected in scientific operation mode. The First LAT AGN Catalog (1LAC) includes 671 γ-ray sources located at high Galactic latitudes (|b|>10°) that are detected with a test statistic greater than 25 and associated statistically with AGNs. Some LAT sources are associated with multiple AGNs, and consequently, the catalog includes 709 AGNs, comprising 300 BL Lacertae objects, 296 flat-spectrum radio quasars, 41 AGNs of other types, and 72 AGNs of unknown type. We also classify the blazars based on their spectral energy distributions as archival radio, optical, and X-ray data permit. In addition to the formal 1LAC sample, we provide AGN associations for 51 low-latitude LAT sources and AGN “affiliations” (unquantified counterpart candidates) for 104 high-latitude LAT sources without AGN associations. The overlap of the 1LAC with existing γ-ray AGN catalogs (LBAS, EGRET, AGILE, Swift, INTEGRAL, TeVCat) is briefly discussed. Various properties—such as γ-ray fluxes and photon power-law spectral indices, redshifts, γ-ray luminosities, variability, and archival radio luminosities—and their correlations are presented and discussed for the different blazar classes. We compare the 1LAC results with predictions regarding the γ-ray AGN populations, and we comment on the power of the sample to address the question of the blazar sequence.
Multiband Superconductivity in KFe2As2 : Evidence for one Isotropic and several Liliputian Energy Gaps

We report a detailed low-temperature thermodynamic investigation (heat capacity and magnetization) of the superconducting state of KFe 2 As 2 for H || c axis. Our measurements reveal that the properties of KFe 2 As 2 are dominated by a relatively large nodeless energy gap (∆ 0 = 1.9 k B T c) which excludes d x 2 −y 2 symmetry. We prove the existence of several additional extremely small gaps (∆ 0 < 1.0 k B T c) that have a profound impact on the low-temperature and low-field behavior, similar to MgB 2 , CeCoIn 5 and PrOs 4 Sb 12. The zero-field heat capacity is analyzed in a realistic self-consistent 4-band BCS model which qualitatively reproduces the recent laser ARPES results of Okazaki et al. (Science 337 (2012) 1314). Our results show that extremely low-temperature measurements, i.e. T < 0.1 K,will be required in order to resolve the question of the existence of line nodes in this compound.
An Introduction to Singular Stochastic PDEs

These notes have been prepared for a series of lectures given at the Sarajevo Stochastic Analysis Winter School, from January 28 to February 1, 2019. There already exist several excellent lecture notes and reviews on the subject, such as (Hairer 2009) on (non-singular) stochastic PDEs, and (Hairer 2015, Chandra and Weber 2017) on singular stochastic PDEs and regularity structures. The present notes have two main specificities. The first one is that they focus on a particular example, the Allen-Cahn equation, which allows to introduce several of the difficulties of the theory in a gradual way, by increasing the space dimension step by step. The hope is that while this limits the generality of the theory presented, this limitation is more that made up by a gain in clarity. The second specific aspect of these notes is that they go beyond existence and uniqueness of solutions, by covering a few recent results on convergence to equilibrium and metastability in these system.
HIDDEN DOUBLE-PEAKED EMITTERS IN SEYFERT 2 GALAXIES

We present the detection of extremely broad, double-peaked, highly polarized Hα emission lines in the nuclei of the well-known Seyfert 2 galaxies NGC 2110 and NGC 5252. These hidden broad Hα emission lines, visible only in scattered light, are shown to display significant variability in strength and profile on timescales of ≲1 yr. That the broad emission line exhibits variability in polarized flux also suggests that the scattering region must be very compact, possibly confined in a small number of electron clouds ≲1 lt-yr in size. Our observational constraints place these clouds within ∼10 pc of the nucleus with temperatures Te ≲ 106 K and densities ne ∼ 107 cm−3, consistent with a region just outside the obscuring torus between the broad-line region and narrow-line region. These scattering clouds could arise from the clumpy torus itself. These findings and other properties indicate that NGC 2110 and NGC 5252 are the hidden counterparts to the broad-line double-peaked emission-line active galactic nuclei, whose examples include Arp 102B and 3C 332.
Constraining the rate and luminosity function of Swift gamma-ray bursts

We compute the intrinsic isotropic peak luminosity function (LF) and formation rate of long gamma-ray bursts (LGRBs) using a novel approach. We complement a standard log\,$N$\,--\,log\,$P$ brightness distribution and $V_{\mathrm{max}}$ estimations with two observation-time relations: a redshift--observation-time relation (log\,$z$\,--\,log\,$T$) and a new luminosity--observation-time relation (log\,$L$\,--\,log\,$T$). We show that this approach reduces degeneracies that exist between the rate and LF of a brightness distribution. To account for the complex triggering algorithm employed by \emph{Swift} we use recent results of \citet{Lien_2014ApJ} to produce a suite of efficiency functions. Using these functions with the above methods, we show that a log\,$L$\,--\,log\,$T$ method can provide good constraints on the form of the LF, particularly the high end. Using a sample of 175 peak luminosities determined from redshifts with well defined selection criteria our results suggest that LGRBs occur at a local rate (without beaming corrections) of $[\,0.7 < \rho_{0} < 0.8\,]\,\mathrm{Gpc}^{-3}\mathrm{yr}^{-1}$. Within this range, assuming a broken-power-law LF, we find best estimates for the low and high energy indices of $-0.95 \pm 0.09$ and $-2.59 \pm0.93$ respectively, separated by a break luminosity $0.80 \pm0.43 \times 10^{52}$\,erg\,s$^{-1}$.
Seismic metamaterial: how to shake friends and influence waves?

Materials engineered at the micro- and nano-meter scale have had a tremendous and lasting impact in photonics and phononics, with applications ranging from periodic structures disallowing light and sound propagation at stop band frequencies, to subwavelength focussing and cloaking with metamaterials. Here, we present the description of a seismic test held on a soil structured at the meter scale using vibrocompaction probes. The most simplistic way to interact with a seismic wave is to modify the global properties of the medium, acting on the soil density and then on the wave velocity. The main concept is then to reduce the amplification of seismic waves at the free surface, called site effects in earthquake engineering. However, an alternative way to counteract the seismic signal is by modifying the distribution of seismic energy thanks to a metamaterial made of a grid of vertical, cylindrical and empty inclusions bored in the initial soil, in agreement with numerical simulations using an approximate plate model.
Validation of BAP (6 – Benzyl Amino Purine) Concentration on the Micropropagation of Rose through Shoot Tip Culture

:- In this study, the nodal explants collected from the healthy shoots were cultured on the basal MS medium supplemented with 3mg/lit of BAP (6-Benzyl Amino Purine). In the earlier study, several researchers reported that the concentration of 3mg/lit is optimum for the growth and development of shoot tip in rose by the duration of 1month. The different stage of shoot development was observed from the third day to one month interval. It revealed that the callus initiation starts from the 10 th day and auxillary shoot initiation from 2 weeks, and subsequent growth and development was observed from the third week and one month interval respectively. Further the developed healthy shoot culture will be maintained and will be treated with NAA at different concentration for root initiation. Finally, the optimum concentration of NAA will be fixed for better root
Team goal-setting and collaborative value within Ashoka fellows' organizations in Africa: The mediating role of intra-organizational social capita

Since the Ashoka mission is Everyone a Changemaker, the assumption is that Ashoka Fellows’organizations in Africa are setting goals that contribute to transformative solutions for Africa.Therefore, a study of 154 Ashoka Fellows organizations working in 19 countries in Africa was carriedout to investigate the effect of team goal-setting on collaborative value. Data was collected using astructured questionnaire and in-depth interviews and analysed through a combined descriptive andinferential statistics. The study's specific elements addressed on team goal setting were clarity,commitment, and capacity of team members. The path analysis confirmed a positive relationship witha P-value of 8.6% between Team Goal Setting and Collaborative Value. Further, intra-organizationalsocial capital significantly mediates the relationship between team goal-setting and collaborative valuewith a P-value of 24.5%. Teams need to adapt social capital to support the team members in their abilityto interact, experiment, and achieve common goals, strengthening the team members’ shared sense ofpurpose and understanding of who they are as a collective.
NBER WORKING PAPER SERIES HOUSING WEALTH EFFECTS : THE LONG VIEW

We provide new, time-varying estimates of the housing wealth effect back to the 1980s. We exploit systematic differences in city-level exposure to regional house price cycles to instrument for house prices. Our main findings are that: 1) Large housing wealth effects are not new: we estimate substantial effects back to the mid 1980s; 2) Housing wealth effects were not particularly large in the 2000s; if anything, they were larger prior to 2000; and 3) There is no evidence of a boom-bust asymmetry. We compare these findings to the implications of a standard life-cycle model with borrowing constraints, uninsurable income risk, illiquid housing, and longterm mortgages. The model explains our empirical findings about the insensitivity of the housing wealth effects to changes in the loan-to-value (LTV) distribution, including the dramatic rise in LTVs in the Great Recession. The insensitivity arises in the model for two reasons. First, impatient low-LTV agents have a high elasticity. Second, a rightward shift in the LTV distribution increases not only the number of highly sensitive constrained agents but also the number of underwater agents whose consumption is insensitive to house prices.

Optimal lower bounds for eigenvalues of linear and nonlinear Neumann problems

In this paper we prove a sharp lower bound for the first non-trivial Neumann eigenvalue μ1(Ω) for the p-Laplace operator (p > 1) in a Lipschitz bounded domain Ω in ℝn. Our estimate does not require any convexity assumption on Ω and it involves the best isoperimetric constant relative to Ω. In a suitable class of convex planar domains, our bound turns out to be better than the one provided by the Payne—Weinberger inequality.
Widespread Presence of Glycolaldehyde and Ethylene Glycol around Sagittarius B2

We report the detection of widespread CH2OHCHO and HOCH2CH2OH emission in Galactic center giant molecular cloud Sagittarius B2 using the Shanghai Tianma 65 m Radio Telescope. Our observations show for the first time that the spatial distribution of these two important prebiotic molecules extends over 15 arcmin, corresponding to a linear size of approximately 36 pc. These two molecules are not just distributed in or near the hot cores. The abundance of these two molecules seems to decrease from the cold outer region to the central region associated with star formation activity. Results presented here suggest that these two molecules are likely to form through a low temperature process. Recent theoretical and experimental studies demonstrated that prebiotic molecules can be efficiently formed in icy grain mantles through several pathways. However, these complex ice features cannot be directly observed, and most constraints on the ice compositions come from millimeter observations of desorbed ice chemistry products. These results, combined with laboratory studies, strongly support the existence of abundant prebiotic molecules in ices.
HST/ACS OBSERVATIONS OF RR LYRAE STARS IN SIX ULTRA-DEEP FIELDS OF M31

We present HST/ACS observations of RR Lyrae variable stars in six ultra-deep fields of the Andromeda galaxy (M31), including parts of the halo, disk, and giant stellar stream. Past work on the RR Lyrae stars in M31 has focused on various aspects of the stellar populations that make up the galaxy's halo, including their distances and metallicities. This study builds upon this previous work by increasing the spatial coverage (something that has been lacking in previous studies) and by searching for these variable stars in constituents of the galaxy not yet explored. Besides the 55 RR Lyrae stars we found in our initial field located 11 kpc from the galactic nucleus, we find additional RR Lyrae stars in four of the remaining five ultra-deep fields as follows: 21 in the disk, 24 in the giant stellar stream, three in the halo field 21 kpc from the galactic nucleus, and five in one of the halo fields at 35 kpc. No RR Lyrae stars were found in the second halo field at 35 kpc. The RR Lyrae populations of these fields appear to be mostly of Oosterhoff I type, although the 11 kpc field appears to be intermediate or mixed. We will discuss the properties of these stars including period and reddening distributions. We calculate metallicities and distances for the stars in each of these fields using different methods and compare the results, to an extent that has not yet been done. We compare these methods not just on RR Lyrae stars in our M31 fields, but also on a data set of Milky Way field RR Lyrae stars.
Integrability criterion in terms of coprime property for the discrete Toda equation

We reformulate the singularity confinement of the discrete Toda equation. We prove the co-primeness property, which has been introduced in our previous paper (arXiv:1311.0060) as one of the integrability criteria, for the discrete Toda equation. We study three types of boundary conditions (semi-infinite, molecule, periodic) for the discrete Toda equation, and prove that the same co-primeness property holds for all the types of boundaries. (v2: typos corrected, final version to appear in J. Math. Phys.)
Measurement and Analysis of Crowdsourced Vehicle Vibration Levels during Last Mile Delivery Segments for Parcel Shipments

: Crowdsourced logistics has emerged as a delivery channel for many single-parcel packages. As a result, this logistics network has introduced personal passenger vehicles as a means to transport parcels during last mile delivery segments. To understand this network’s vibration levels and cargo capacity restraints, four vehicle types (a sedan, sports sedan, compact SUV and full-size SUV) commonly used in crowdsourced logistics deliveries were selected for measurement and analysis. This study shows that the vibration levels were significantly higher in the vertical axis and that the overall vibration energy increased as vehicle speed increased, except in the sedan. The sedan and SUV vehicles showed power spectral density peak frequencies in the low-frequency range, occurring at approximately 2 Hz, matching previous studies using similar vehicles. The vibration levels were greatest in the sports sedan and lowest in the sedan. The recorded vibration events showed a right-skewed heavy-tailed distribution and were non-Gaussian.
