Period - magnitude relationships in BVIJHK-Bands for fundamental mode and first overtone Cepheids

description: We present theoretical period - magnitude relationships for Cepheids in different filters for fundamental and first overtone pulsators, completing the work by Alibert et al. (1999). The results are provided for different metallicities characteristic of the Magellanic Clouds and the Milky Way. In contrast to the fundamental mode, we find a small metallicity effect on the period - luminosity relationship for the first overtone, due to the sensitivity of the period ratio $P_1$/$P_0$ with metallicity. Comparison is made with observations from OGLE and EROS in the Small and Large Magellanic Clouds. We emphasize the constraint on theoretical predictions provided by the combination of both fundamental and first overtone observed sequences. We obtain excellent agreement between models and data in a $\log P$ - $\wi$ (Wesenheit index) diagram for a distance modulus for the LMC $μ_0$ = 18.60 - 18.70. We analyse the uncertainties of the fundamental period - magnitude relationships and the consequences on distance determination. We show that an arbitrary shift of the instability strip by 350 K in $\te$ yields up to 0.45 mag effect on $\mv$ at a given period, whereas the effect is less than 0.1 mag in the $K$-band. Using recent near-IR observations in the Large Magellanic Cloud and our $P$ - $\mk$ relationship, we derive a distance modulus for the LMC in agreement with the value based on $\wi$ data.

description: High-resolution (R ~ 90,000) spectra of 34 nearby, young Sun-like stars were analyzed using stellar atmosphere models to estimate effective photosphere temperatures, surface gravities, and the abundance of certain heavy elements (C, Na, Mg, Si, S, Ca, Ti, Fe, and Ni). The effective temperatures derived from spectroscopy were compared with temperatures estimated using optical and near-infrared photometry. In many cases the spectroscopic temperatures are significantly higher than the photometric estimates, possibly as a result of spottedness or chromospheric activity on these active stars. Values of effective temperature, surface gravity, and luminosity were compared to theoretical stellar evolution tracks and the evolutionary status of these objects was evaluated. The correlation between heavy element abundance patterns and kinematics (space motion) was also examined. Two nearby stars that were tentatively assigned to the Hyades cluster based on kinematics have Fe abundances that are also consistent with membership in that cluster. Members of the Ursa Major kinematic group exhibit a range of [Fe/H] values but have monotonic [Si/Fe]. These two observations suggest that heterogeneous incorporation of the heavy elements into protostars is creating the variation in metallicity. Local Association members have a distinctly different Si/Fe that probably reflects their distinct origin and chemical inheritance.

description: Natural products have proven to be effective in fighting various human diseases. The identification of bioactive natural products is an efficient method of finding new drug leads. Screening of natural product extracts on therapeutic targets for the presence of active compounds is a rapid and effective strategy to identify noncovalent interactions between active ligands from natural product extracts and their therapeutic protein targets. This thesis presents an effort of exploring a novel approach to screen natural product extracts using bioaffinity mass spectrometry against malarial targets and studies the relationship between HPLC retention time and Log P values of natural products. With an aim to identify noncovalent complexes and to obtain chemical information of active compounds at the screening stage as well as exploit the connection between HPLC retention time and Log P values of chemical constituents isolated from the active extracts, a research plan containing four major steps has been undertaken in this study. Step one includes understanding of mass spectrometry technique and its approaches in drug discovery screening, understanding of physicochemical properties of antimalarial natural products and using ChemGPS to assess drug potential of reported anti-malarial natural products.
Seyfert-Type Dependences of Narrow Emission-Line Ratios and Physical Properties of High-Ionization Nuclear Emission-Line Regions in Seyfert Galaxies

description: In order to examine how narrow emission-line flux ratios depend on the Seyfert type, we compiled various narrow emission-line flux ratios of 355 Seyfert galaxies from the literature. We present in this paper that the intensity of the high-ionization emission lines, [Fe VII]6087, [Fe X]6374 and [Ne V]3426, tend to be stronger in Seyfert 1 galaxies than in Seyfert 2 galaxies. In addition to these lines, [O III]4363 and [Ne III]3869, whose ionization potentials are not high (< 100 eV), but whose critical densities are significantly high (> 10^7 cm^-3), also exhibit the same tendency. On the other hand, the emission-line flux ratios among low-ionization emission lines do not show such a tendency. We point out that the most plausible interpretation of these results is that the high-ionization emission lines arise mainly from highly-ionized, dense gas clouds, which are located very close to nuclei, and thus can be hidden by dusty tori. To examine the physical properties of these highly-ionized dense gas clouds, photoionization model calculations were performed. As a result, we find that the hydrogen density and the ionization parameter of these highly-ionized dense gas clouds are constrained to be n_H > 10^6 cm^-3 and U > 10^-2, respectively. These lower limits are almost independent both from the metallicity of gas clouds and from the spectral energy distribution of the nuclear ionizing radiation.

description: Recent detections by the gravitational wave facilities LIGO/Virgo have opened a window to study the internal structure of neutron stars through the gravitational waves emitted during their coalescence. In this work we explore, through numerical simulations, the gravitational radiation produced by the merger of binary neutron stars with dark matter particles trapped on their interior, focusing on distinguishable imprints produced by these dark matter cores. Our results reveal the presence of a strong m = 1 mode in the waveforms during the post-merger stage, together with other relevant features. Comparison of our results with observations might allow us to constraint the amount of dark matter in the interior of neutron star.

description: We review highlights of the results obtained from recent Galactic X-ray survey observations, in particular ASCA Galactic center and plane survey and our Chandra deep survey on the (l,b)=(28.5,0) region. Strong hard X-ray diffuse components are observed from Galactic ridge, center and bulge, and they have both thermal and non-thermal spectral components. Dozens of discrete and extended sources have been discovered on the Galactic plane, which also indicate thermal and/or non-thermal X-ray energy spectra. They are often associated with radio sources and are considered to be SNR candidates. Most of the hard X-ray point sources in the outer part of the Galactic plane are considered to be background AGNs, while fraction of the Galactic hard X-ray sources (such as quiescent dwarf novae) increases toward the Galactic center. Most of the soft X-ray sources on the Galactic plane are presumably nearby active stars.

description: We present X-ray spatial and spectral analysis of the Chandra data from the central 400 kpc (H0 = 50 km/s/Mpc) of the cluster of galaxies Abell 1795. The plasma temperature rises outwards by a factor of 3, whereas the iron abundance decreases by a factor of 4. The spatial distribution of Oxygen, Neon, Sulphur, Silicon and Iron shows that supernovae Type Ia dominate the metal enrichment process of the cluster plasma within the inner 150 kpc. Resolving both the gas density and temperature in 9 radial bins, we recover the gravitational mass density profile and show that it flattens within 100 kpc as rho_DM \propto r^{-0.6} with a power law index flatter than -1 at >3 sigma level. The observed motion of the central galaxy and the presence of excesses and deficits along the North-South direction in the brightness distribution indicate that the central cluster region is not relaxed. In the absence of any non-gravitational heating source, the data from the inner ~200 kpc indicate the presence of a cooling flow with an integrated mass deposition rate of about 100 Msun/yr. Over the same cluster region, the observed rate of 74 Msun/yr is consistent with the recent XMM Reflection Grating Spectrometer limit of 150 Msun/yr.

description: Abstracts Book, 13th International Congress of Medical Sciences 30 April – 2 May 2008 , Islamic Azad University, Tabriz , Iran , p:206 Abstract: Background: Nasocominal infections (NI) are one of the most important problems in the world. This survey is about knowledge and practice of nurses about nasocominal infection control. Methods: 163 nurses completed a questionnaire consisting of 30 knowledge and 30 practice items. Results: 5.5% from nurses had weak knowledge, 51.2% average knowledge and 43.3% good knowledge. However, 3.7% nurses had weak practice, 16.5% had average practice and 79.8% had good practice. There were significant correlation between knowledge and practice (p<0.05). In addition, there were no correlation between demographic information (except sex) and knowledge and practice (p>0.05). Conclusion: Although good knowledge is important for good practice, it is not sufficient. It seems that practical training of nurses is necessary for techniques of NI control.

description: Dimethylsilanediol (DMSD) is a highly water-soluble degradation product of dimethylsiloxane oligomer and polymer materials that may be found in the environment. In this project, we have developed a water analysis method for DMSD based on liquid chromatography-triple quadrupole tandem mass spectrometry (LC/QQQ MS/MS) using 13C-DMSD as an internal standard with and without solid phase extraction (SPE). This included the modification of SPE extraction method for water samples with colloidal particles that may plug the SPE cartridge, the use of a water-based solvent mixture for DMSD elution to promote better ionisation in instrumental analysis and optimisation of instrumental operation conditions for higher sensitivity in QQQ MS/MS analysis. The water method was successfully applied for analysis of DMSD in soil, sediment and biosolids by coupling the water extraction of DMSD from solid samples with the pre-column SPE extraction of the water extracts. The method detection limit (MDL) for direct water analysis was found to be as low as 2 μg L−1, while the current MDLs for sediment, soil and biosolids are in the range of 10 to 100 ng g−1 dw. The matrix spike recovery varied from 79% to 99% for all samples, confirming its general validity of the method. Compared with the published methods, this method requires less sample processing and has lower MDLs for DMSD analysis in environmental samples.

description: Young stars in the solar neighborhood serve as nearby probes of stellar evolution and represent promising targets to directly image self-luminous giant planets. We have carried out an all-sky search for late-type ($\approx$K7$-$M5) stars within 100 pc selected primarily on the basis of activity indicators from $GALEX$ and $ROSAT$. Approximately two thousand active and potentially young stars are identified, over 600 of which we have followed up with low-resolution optical spectroscopy and over 1000 with diffraction-limited imaging using Robo-AO at the Palomar 1.5-m telescope. Strong lithium is present in 58 stars, implying ages spanning $\approx$10$-$200 Myr. Most of these lithium-rich stars are new or previously known members of young moving groups including TWA, $β$ Pic, Tuc-Hor, Carina, Columba, Argus, AB Dor, Upper Centaurus Lupus, and Lower Centaurus Crux; the rest appear to be young low-mass stars without connections to established kinematic groups. Over 200 close binaries are identified down to 0.2$''$ $-$ the vast majority of which are new $-$ and will be valuable for dynamical mass measurements of young stars with continued orbit monitoring in the future.

description: Do affective attitudes determine voting behavior? As a part of this broad question, we examine how third-party supporters’ affective attitudes decide their strategic voting behavior. Using seven waves of the British Election Study (2015, 2017, and 2019), we find that third-party supporters whose affective attitudes toward the two principal political parties in their constituency are more polarized are more inclined to vote strategically. The results imply that voting behavior is shaped by both feelings toward as well as cognitive evaluations of political parties. They also imply that British voters may increasingly engage in strategic voting if the level of affective polarization continues to rise. Lastly, and more generally, the results imply that all political parties should pay attention to voter “feelings” if they are to maximize their electoral support.

description: We study a possible deconfined quantum phase transition in a realistic model of a two-dimensional Shastry-Sutherland quantum magnet, using both numerical and field theoretic techniques. Using the infinite density matrix renormalization group (iDMRG) method, we verify the existence of an intermediate plaquette valence bond solid (pVBS) order, with two fold degeneracy, between the dimer and Néel ordered phases. We argue that the quantum phase transition between the Néel and pVBS orders may be described by a deconfined quantum critical point (DQCP) with an emergent O(4) symmetry. By analyzing the correlation length spectrum obtained from iDMRG, we provide evidence for the DQCP and emergent O(4) symmetry in the lattice model. Such a phase transition has been reported in the recent pressure tuned experiments in the Shastry-Sutherland lattice material $\mathrm{SrCu_2 (BO_3)_2}$. The non-symmorphic lattice structure of the Shastry-Sutherland compound leads to extinction points in the scattering, where we predict sharp signatures of a DQCP in both the phonon and magnon spectra associated with the spinon continuum. The effect of weak interlayer couplings present in the three dimensional material is also discussed. Our results should help guide the experimental study of DQCP in quantum magnets.

description: We have used the technique of spectro-astrometry to study the milli-arcsecond scale structure of the emission lines in the T Tauri star RU Lupi. The wings of the H-alpha emission are found to be displaced from the star towards the south-west (blue wing) and north-east (red wing) with angular scales of 20-30 milli-arcsecs. This structure is consistent with a bipolar outflow from the star. From a study of the variability of the intensity and position spectra we argue that a combination of magnetically-driven bipolar outflow and accreting gas contribute to the H-alpha emission. On the other hand, the [OI] and [SII] emission are displaced from the star to the south-west but at much larger distances than the H-alpha, hundreds of milli-arcsecs for the high-velocity component (HVC) and down to 30 milli-arcsecs for the low-velocity components (LVC). The presence of both red-shifted and blue-shifted outflows in H-alpha but only a blue-shifted outflow in the forbidden lines can be explained if the disc obscures the red-shifted forbidden line outflow, but a disc gap with outer radius 3-4 au allows the red-shifted H-alpha to be seen. This gap could be induced by an unseen companion.

description: The ribosome is one of the largest and most complex macromolecular machines in living cells. It polymerizes a protein in a step-by-step manner as directed by the corresponding nucleotide sequence on the template messenger RNA (mRNA) and this process is referred to as `translation' of the genetic message encoded in the sequence of mRNA transcript. In each successful chemo-mechanical cycle during the (protein) elongation stage, the ribosome elongates the protein by a single subunit, called amino acid, and steps forward on the template mRNA by three nucleotides called a codon. Therefore, a ribosome is also regarded as a molecular motor for which the mRNA serves as the track, its step size is that of a codon and two molecules of GTP and one molecule of ATP hydrolyzed in that cycle serve as its fuel. What adds further complexity is the existence of competing pathways leading to distinct cycles, branched pathways in each cycle and futile consumption of fuel that leads neither to elongation of the nascent protein nor forward stepping of the ribosome on its track. We investigate a model formulated in terms of the network of discrete chemo-mechanical states of a ribosome during the elongation stage of translation. The model is analyzed using a combination of stochastic thermodynamic and kinetic analysis based on a graph-theoretic approach. We derive the exact solution of the corresponding master equations. We represent the steady state in terms of the cycles of the underlying network and discuss the energy transduction processes. We identify the various possible modes of operation of a ribosome in terms of its average velocity and mean rate of GTP hydrolysis. We also compute entropy production as functions of the rates of the interstate transitions and the thermodynamic cost for accuracy of the translation process.

 Discussion. The specimen listed above was examined in 2003 by B. Merz and identified as Stenomicra delicata. However, this record was forgotten and, hence, the specimen was not revised by MERZ & ROHÁČEK (2005). During my 2011 visit in the Naturhistoriska Riksmuseet (Stockholm), the specimen was re-examined and found to belong to S. soniae. ROHÁČEK (2009) discussed the probable occurrence of S. soniae in Sweden (Småland) on the basis of notes by ANDERSSON (1991) but stated that without the revision of a voucher specimen this record cannot be verified. Thus, the above listed male specimen represents the first reliable record from Sweden (Södermanland) and the northernmost known locality of S. soniae.
 Distribution. Hitherto the species has been recorded from Switzerland, Germany, Czech Republic (Bohemia, Moravia), Slovakia, Romania, Bulgaria (see MERZ & ROHÁČEK 2005), northern Italy (VON TSCHIRNHAUS 2008) and Sweden (new).

description: The bacterial flagellar motor is an ion-powered transmembrane protein complex which drives swimming in many bacterial species. The motor consists of a cytoplasmic 'rotor' ring and a number of 'stator' units, which are bound to the cell wall of the bacterium. Recently, it has been shown that the number of functional torque-generating stator units in the motor depends on the external load, and suggested that mechanosensing in the flagellar motor is driven via a 'catch bond' mechanism in the motor's stator units. We present a method that allows us to measure -- on a single motor -- stator unit dynamics across a large range of external loads, including near the zero-torque limit. By attaching superparamagnetic beads to the flagellar hook, we can control the motor's speed via a rotating magnetic field. We manipulate the motor to four different speed levels in two different ion-motive force (IMF) conditions. This framework allows for a deeper exploration into the mechanism behind load-dependent remodelling by separating out motor properties, such as rotation speed and energy availability in the form of IMF, that affect the motor torque.

description: TV Columbae (TV Col) is a 13th magnitude Intermediate Polar (IP) Cataclysmic Variable (CV), with multiple periods found in the light curves. Past estimates predicted a distance of 400 parsec to greater than 500 parsec. Recently completed Hubble Space Telescope (HST) Fine Guidance Sensor (FGS) interferometric observations allow us to determine the first trigonometric parallax to TV Col. This determination puts the distance of TV Col at 368 -15+17 parsecs. CD-32 2376, a 10th magnitude Tycho Catalog star, is a reference star in the TV Col frame. We find a distance of $127.7 -1+1 parsecs.

description: We present spectra of the DAB white dwarf PG1115+166. Radial velocity measurements of the Balmer lines and the HeI6678 line show that this is a binary white dwarf with a period of 30.09d in which the Balmer lines move in anti-phase to the HeI line, i.e., PG1115+166 is a DA+DB binary. The minimum masses of the stars are M_DA=0.43+-0.15 solar masses and M_DB=0.52+-0.12 solar masses. The separation of the stars is about 45 solar radii which is much smaller than a typical AGB progenitor of a white dwarf, implying that there has been at least one common envelope phase in this binary. Indeed, it is possible that this binary may have suffered up to three mass transfer episodes - two associated with the red giant phase prior to the formation of each white dwarf and a third associated with the ``born-again'' red giant phase of the DB white dwarf. PG1115+166 has the longest orbital period of any post common envelope white dwarf - white dwarf binary found to date. Published models for the formation of white dwarf - white dwarf binaries do not predict any white dwarfs with the combination of long orbital period and high mass found in PG1115+166. We conclude that PG1115+166 is a key object for testing models of binary star evolution and it may also be a key object for our understanding of the formation of DB white dwarfs. We outline the observational tests which can be applied to scenarios for the formation of PG1115+166 and apply them to the simplest case of a single common envelope phase. This suggests that some part of the internal energy stored in the envelope of the AGB star, e.g., as ionized hydrogen, may have contributed to the ejection of the common envelope, but there are several unanswered questions concerning this simple scenario.

description: American political elites are today more neatly divided on a wider range of issues than at any other point in the postwar era. How have these trends affected the political socialization of American youth? We argue that two distinctive aspects of US polarization, namely ideological alignment and the emergence of non-economic issues, have formed the foundation of a generational shift in favor of the Democratic party. We find that Millennials and Gen Z display levels of ideological alignment across economic, civil rights, and moral domains that are equal to or greater than previous generations. Their liberal positions on moral and civil rights issues are not only strongly predictive of vote choice, but also tend to offset any conservative positions on economic issues – in contrast to the way previous generations resolved such ideological tensions. As such, the push for a non-economic political agenda – a popular strategy in the last few decades, especially among Republicans – might well benefit the Democrats electorally as older generations are replaced.

description: Four new bis-imidazolium salts 3–6 and their di- and polynuclear silver(I)–N-heterocyclic carbene (Ag(I)–NHC) complexes 7–10 were synthesized and characterized by using various analytical techniques. Single-crystal studies of 8 revealed a dinuclear structure whereas that of 9 revealed an interesting polynuclear structure. The quasi-reversibility of redox events in electrochemical study of 9 indicated that reduction produces unstable decomposed species and oxidation may be ascribed to these decomposed species. All the compounds were studied for their in vitro anticancer study against human breast cancer (MDA-MB-231) and colon cancer (HCT-116) cells. The study revealed that Ag(I)–NHC complexes are comparatively more potent than NHC precursors (salts). MDA-MB-231 cells appeared more sensitive to complexes than HCT-116 cells while reverse is the case for NHC salts.

Laws of large numbers for the frog model on the complete graph

description: The frog model is a stochastic model for the spreading of an epidemic on a graph, in which a dormant particle starts to perform a simple random walk on the graph and to awake other particles, once it becomes active. We study two versions of the frog model on the complete graph with $N + 1$ vertices. In the first version we consider, active particles have geometrically distributed lifetimes. In the second version, the displacement of each awakened particle lasts until it hits a vertex already visited by the process. For each model, we prove that as $N \to \infty$, the trajectory of the process is well approximated by a three-dimensional discrete-time dynamical system. We also study the long-term behavior of the corresponding deterministic systems.

description: Observations of the nebula S3 associated with the WO star in the galaxy IC 1613 and of an extended region surrounding S3 are reported. The star and bright core of the nebula were observed with a multipupil fiber spectrograph mounted on the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. Images in the principle spectral lines and integrated spectra of the star and three compact clumps were obtained, and the radial-velocity field constructed. An extended region of the galaxy was observed with the Very Large Array at 21 cm. A giant ring or HI shell enclosing a large fraction of the stellar population in IC 1613 was discovered. The WO star and associated bipolar nebula, which we discovered earlier, lies at the inner edge of the H ring. A local HI deficiency and two arc-like HI ridges were also detected for the first time, and probably represent the neutral component of the bipolar shell surrounding the WO star. The two arc-like ridges may also have been produced by the collective stellar wind (and supernova explosions?) in OB association No. 9 from the list of Hodge. A scenario for the formation of the extended bipolar feature is discussed, based on the new data.

description: Oscillons are bound states sustained by self-interactions that appear in rather generic scalar models. They can be extremely long-lived and in the context of cosmology they have a built-in formation mechanism - parametric resonance instability. These features suggest that oscillons can affect the standard picture of scalar ultra-light dark matter (ULDM) models. We explore this idea along two directions. First, we investigate numerically oscillon lifetimes and their dependence on the shape of the potential. We find that scalar potentials that occur in well motivated axion-like models can lead to oscillons that live up to $10^8$ cycles or more. Second, we discuss the observational constraints on the ULDM models once the presence of oscillons is taken into account. For a wide range of axion masses, oscillons decay around or after matter-radiation equality and can thus act as early seeds for structure formation. We also discuss the possibility that oscillons survive up to today. In this case they can most easily play the role of dark matter.

description: Objective: To investigate the effectiveness and safety of belimumab in patients with active systemic lupus erythematosus (SLE) in a real-life setting. Methods: All SLE patients treated with belimumab in the Department of Autoimmune Diseases of the Hospital Clinic of Barcelona were retrospectively analysed. The Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score, clinical SLEDAI-2K, levels of anti-double-stranded DNA (anti-dsDNA) antibody, complement components C3 and C4, and 50% haemolytic complement activity (CH50) were recorded at baseline and at 6, 12, and 24 months. Adverse events were also collected. Results: Twenty-three patients (100% women) were enrolled in the study. The most frequent manifestations that led to belimumab use were arthritis (91%) and skin involvement (39%). Both SLEDAI-2K and clinical SLEDAI-2K improved over time at all time-points (p Conclusion: In our patients with SLE, belimumab decreased disease activity and allowed tapering of the daily glucocorticoid dose with a good safety profile.
