Contact Discontinuities in Models of Contact Binaries Undergoing Thermal Relaxation Oscillations
Creators: name: Wang, Jian-Min
Publisher: name: arXiv
Year: 1999
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: In this paper we pursue the suggestion by Shu, Lubow & Anderson (1979) and Wang (1995) that contact discontinuity (DSC) may exist in the secondary in the expansion TRO (thermal relaxation oscillation) state. It is demonstrated that there is a mass exchange instability in some range of mass ratio for the two components. We show that the assumption of {\it constant} volume of the secondary should be relaxed in DSC model. For {\it all} mass ratio the secondary alway satisfies the condition that no mass flow returns to the primary through the inner Lagrangian point. The secondary will expand in order to equilibrate the interaction between the common convective envelope and the secondary. The contact discontinuity in contact binary undergoing thermal relaxation does not violate the second law of thermodynamics. The maintaining condition of contact discontinuity is derived in the time-dependent model. It is desired to improve the TRO model with the advanced contact discontinuity layer in future detailed calculations.

description: Relations connecting various zero momentum correlators of interpolating fields for pseudoscalar and scalar channel, containing one heavy and one light quark field, are derived from the Euclidean space formulation of the QCD functional integral. These relations may serve as constraints on the phenomenological models or approaches motivated from QCD, and suggest a method to extract the chiral quark condensates. It is also found that the correlator for pseudoscalar channel differs from that for scalar channel even in the large heavy quark mass limit.

The formation and merger of compact objects in central engine of active galactic nuclei and quasars: gamma-ray burst and gravitational radiation

description: The production rate of compact objects, i.e. neutron stars (NS) and black holes (BH), in active galactic nuclei (AGN) and quasars (QSO), where the frequent supernova explosion is used to explain the high metallicity, is very high due to the interaction between the accretion disk and main sequence stars in the nucleus of the quasar. The compact object-red giant star (RG) binaries can be easily formed due to the large captured cross-section of the red giant stars. The (NS/BH, NS/BH) binary can be formed after the supernova explosion of the (NS/BH, RG) binary. Intense transient gamma-ray emission (gamma-ray burst) and gravitational radiation can result from the merger of these two compact objects. Collision between helium core (Hc) of RG and black hole may also take place and may also result in long duration gamma-ray bursts but no gravitational waves. We estimate that the merger rate of (NS/BH, NS/BH) binaries and (Hc, BH) is proportional to the metal abundance $({\rm \frac{NV}{CIV}})$ and can be as high as 10$^{-3}({\rm \frac{NV}{CIV}}/0.01)$ per year per AGN/QSO.

description: In this note, we examine the scattering of two identical fermions in theories where fermionic fields minimally coupled to higher derivative gravity. In particular, we consider the extension of general relativity with $R^2$ corrections or non-local terms. We expand the action of fermions around the flat space background and obtain two fermion-one graviton vertex. Then, by considering the scattering amplitude of two fermions, we calculate the non-relativistic limit and that obtain the potential for two fermion-fermion interaction which would be the usual Newtonian potential corrected with a Yukawa-like term. At the end, we briefly discuss the astronomical effects of such Yukawa-like potential by computing the gravitational pressure of a spherical star and use it for a white dwarf to obtain quantum corrections of Chandrasekhar radius.

description: We present the ASCA results of imaging spectroscopy of the giant molecular cloud Sgr B2. The X-ray spectrum is found to be very peculiar; it exhibits a strong emission line at 6.4 keV, a low energy cutoff below about 4 keV and a pronounced edge-structure at 7.1 keV. The X-ray image is extended and its peak position is shifted from the core of the molecular cloud toward the Galactic center by about 1--2 arcminute. The X-ray spectrum and the morphology are well reproduced by a scenario that X-rays from an external source located in the Galactic center direction are scattered by the molecular cloud Sgr B2, and come into our line of sight. Thus Sgr B2 may be called an X-ray reflection nebula. Possible implications of the Galactic center activity related to this unique source are presented.

description: Imidazolones are potent for their intense antimicrobial and mitigating exercises wherein, an assortment of imidazolone analogs 4-aryl-1-(4-chloro-3-fluorophenyl)-2-phenyl-1H-imidazol-5(4H)-ones (2a-o) and 4-aryl-2-phenyl-1-(4-(trifluoromethyl) phenyl)-1H-imidazol-5(4H)-ones (3a-o) were studied amalgamating them by using oxazolones and various aryl amines. Newly synthesized compounds were screened for in vitro activity towards bacterial as well as fungal pathogenic microscopic organisms. Among the synthesized imidazolone derivatives, compound 2f, 2g, 2i, 3b, 3h, and 3k showed moderate antibacterial action while 2d, 2j, 2m, 2n, 3e, 3g, and 3f furnished earmarked antifungal action. In-silico docking of all structures was performed for fungal and bacterial targets. Out of all novel imidazolones, the compounds 2e, 2o and 3o exhibited superior affinity against fungal target 14α-demethylase when compared with other compounds.

description: This paper aims to shed light on alternative news media ecosystems that are believed to have influenced opinions and beliefs by false and/or biased news reporting during the 2016 US Presidential Elections. We examine a large, professionally curated list of 668 hyper-partisan websites and their corresponding Facebook pages, and identify key characteristics that mediate the traffic flow within this ecosystem. We uncover a pattern of new websites being established in the run up to the elections, and abandoned after. Such websites form an ecosystem, creating links from one website to another, and by `liking' each others' Facebook pages. These practices are highly effective in directing user traffic internally within the ecosystem in a highly partisan manner, with right-leaning sites linking to and liking other right-leaning sites and similarly left-leaning sites linking to other sites on the left, thus forming a filter bubble amongst news producers similar to the filter bubble which has been widely observed among consumers of partisan news. Whereas there is activity along both left- and right-leaning sites, right-leaning sites are more evolved, accounting for a disproportionate number of abandoned websites and partisan internal links. We also examine demographic characteristics of consumers of hyper-partisan news and find that some of the more populous demographic groups in the US tend to be consumers of more right-leaning sites.

description: The study of solar neutrinos may provide important insights into the physics of the central region of the Sun. Four solar neutrino experiments have confirmed the solar neutrino problem but do not clearly indicate whether solar physics, nuclear physics, or neutrino physics have to be improved to solve it. Nonlinear relations among the different neutrino fluxes are imposed by two coupled systems of differential equations governing the internal structure and time evolution of the Sun. We assume that the results of the four neutrino experiments are correct and are concerned not with the discrepancy between the average rate and the predicted rate, but with a possible time dependence of the argon production rate as revealed in the Homestake experiment over a time period of 20 years. Based on the subtlety of the solar neutrino problem we review here quantitatively the physical laws employed for understanding the internal solar structure and conjecture that the interlink between specific nuclear reactions of the PPIII-branch of the proton-proton chain may allow the high-energy solar neutrino flux to vary over time.

A Far-Infrared Survey of Molecular Cloud Cores

description: We present a catalogue of molecular cloud cores drawn from high latitude, medium opacity clouds, using the all-sky IRAS Sky Survey Atlas (ISSA) images at 60 and 100~$μ$m. The typical column densities of the cores are $ N(H_2)\sim 3.8 \times 10^{21} $cm$^{-2}$ and the typical volume densities are $ n(H_2) \sim 2 \times 10^3$cm$^{-3}$. They are therefore significantly less dense than many other samples obtained in other ways. Those cloud cores with IRAS point sources are seen to be already forming stars, but this is found to be only a small fraction of the total number of cores. The fraction of the cores in the protostellar stage is used to estimate the prestellar timescale - the time until the formation of a hydrostatically supported protostellar object. We argue, on the basis of a comparison with other samples, that a trend exists for the prestellar lifetime of a cloud core to decrease with the mean column density and number density of the core. We compare this with model predictions and show that the data are consistent with star formation regulated by the ionisation fraction.

description: This manuscript is about the identification of degradation products and four related substances of a novel antihistaminic drug Bilastine by LC-Q-TOF-MS/MS. A selective stability-indicating RP-HPLC method was developed for the separation of Bilastine, its 4 related substances and degradation products. Separation was done through Inertsil ODS-3® column (150 x 4.6 mm, 5 µm) using 10 mM ammonium acetate (pH 6.00) and methanol as eluent in a gradient at 1.0 mL/min flow rate. The chromatogram was extracted at 275 nm wavelength. Two degradation products and four related substances were identified and their structures were proposed on the basis of data obtained from LC-Q-TOF-MS/MS experiments. The developed method was validated in accordance with ICH Q2 and USP <1225> guidelines and it was found to be specific, precise, accurate and robust for the intended use. The method was linear in the range of 160-240 µg/mL for drug and 1.15-4.5 µg/mL for related substances with R2 value greater than 0.999 and 0.997 for drug and RS respectively. Percentage of relative standard deviation for validated parameters was less than 2. Structures of the drug, its degradation products and related substances were subjected to in silico studies for prediction of physicochemical, pharmacokinetic and toxicological properties with the help of QikProp module of Schrödinger suite 2017-1 software. Predicted in silico values suggested that they are safe and lie within the recommended range of parameters.

description: We have observed a complex and continuous change in the integrated pulse profile of PSR B2217+47, manifested as additional components trailing the main peak. These transient components are detected over 6 years at $150$ MHz using the LOw Frequency ARray (LOFAR), but they are not seen in contemporaneous Lovell observations at $1.5$ GHz. We argue that propagation effects in the ionized interstellar medium (IISM) are the most likely cause. The putative structures in the IISM causing the profile variation are roughly half-way between the pulsar and the Earth and have transverse radii $R \sim 30$ AU. We consider different models for the structures. Under the assumption of spherical symmetry, their implied average electron density is $\overline{n}_e \sim 100$ cm$^{-3}$. Since PSR B2217+47 is more than an order of magnitude brighter than the average pulsar population visible to LOFAR, similar profile variations would not have been identified in most pulsars, suggesting that subtle profile variations in low-frequency profiles might be more common than we have observed to date. Systematic studies of these variations at low frequencies can provide a new tool to investigate the proprieties of the IISM and the limits to the precision of pulsar timing.

description: From reducing stress and loneliness, to boosting productivity and overall well-being, pets are believed to play a significant role in people's daily lives. Many traditional studies have identified that frequent interactions with pets could make individuals become healthier and more optimistic, and ultimately enjoy a happier life. However, most of those studies are not only restricted in scale, but also may carry biases by using subjective self-reports, interviews, and questionnaires as the major approaches. In this paper, we leverage large-scale data collected from social media and the state-of-the-art deep learning technologies to study this phenomenon in depth and breadth. Our study includes four major steps: 1) collecting timeline posts from around 20,000 Instagram users, 2) using face detection and recognition on 2-million photos to infer users' demographics, relationship status, and whether having children, 3) analyzing a user's degree of happiness based on images and captions via smiling classification and textual sentiment analysis, 3) applying transfer learning techniques to retrain the final layer of the Inception v3 model for pet classification, and 4) analyzing the effects of pets on happiness in terms of multiple factors of user demographics. Our main results have demonstrated the efficacy of our proposed method with many new insights. We believe this method is also applicable to other domains as a scalable, efficient, and effective methodology for modeling and analyzing social behaviors and psychological well-being. In addition, to facilitate the research involving human faces, we also release our dataset of 700K analyzed faces.

description: The transition from earlier lighting technologies to white light-emitting diodes (LEDs) is a significant change in the use of artificial light at night. LEDs emit considerably more short-wavelength light into the environment than earlier technologies on a per-lumen basis. Radiative transfer models predict increased skyglow over cities transitioning to LED unless the total lumen output of new lighting systems is reduced. The City of Tucson, Arizona (U.S.), recently converted its municipal street lighting system from a mixture of fully shielded high- and low-pressure sodium (HPS/LPS) luminaires to fully shielded 3000 K white LED luminaires. The lighting design intended to minimize increases to skyglow in order to protect the sites of nearby astronomical observatories without compromising public safety. This involved the migration of over 445 million fully shielded HPS/LPS lumens to roughly 142 million fully shielded 3000 K white LED lumens and an expected concomitant reduction in the amount of visual skyglow over Tucson. SkyGlow Simulator models predict skyglow decreases on the order of 10-20% depending on whether fully shielded or partly shielded lights are in use. We tested this prediction using visual night sky brightness estimates and luminance-calibrated, panchromatic all-sky imagery at 15 locations in and near the city. Data were obtained in 2014, before the LED conversion began, and in mid-2017 after approximately 95% of $\sim$18,000 luminaires was converted. Skyglow differed marginally, and in all cases with valid data changed by $

description: Synthesis of novel Schiff base from 2-hydroxy-6-methylquinolin-3-carbaldehyde and 4-methyl-benzenesulfonohydrazide has been carried out in the present work. Also, the metal complexes of Cu(II), Ni(II), Co(II) and Cd(II) have been synthesized. Schiff base and metal complexes were characterized by various analytical techniques such as CHN analyzer, XRD, FT-IR, UV-Visible, ESR, 1H NMR, 13C NMR, MASS and TGA. Very low value of molar conductance indicates non electrolytic nature of the complexes. The analytical data shows that the ratio of metal to ligand in Cu(II), Ni(II), Co(II) and Cd(II) complexes is 1:2. FT-IR spectral data suggest that the ligand behaves as a tridentate O, N, O donor system. Magnetic susceptibility measurements reveal the paramagnetic behavior of all the complexes except Cd-complex. Further, the Schiff base and the metal complexes were screened for their antimycobacterial activity against M. Bovis BCG and M. tuberculosis H37Ra strains. Compounds 7, 8a, 8c & 8d exhibit very promising results against M. Bovis BCG and MTB H37Ra strains. Among all, Cu-complex shows highest MIC (2.8) value.

description: Objective determination of a star formation history from a colour-magnitude diagram, independently of assumed parametric descriptions, is necessary to determine the evolutionary history of a galaxy. We introduce a new method for solving maximum likelihood problems through variational calculus, and apply it to the case of recovering an unknown star formation history, SFR(t), from a colour-magnitude diagram. This method provides a non-parametric solution with the advantage of requiring no initial assumptions on the SFR(t). As a full maximum likelihood statistical model is used, one may exploit all the information available in the photometric data which can be explained by available isochrones. Extensive tests of the method show it to be reliable under noise conditions comparable to those appropriate for real observations. Implications for future surveys, such as the GAIA mission are significant: accurate determination of the evolutionary history of the Milky Way is limited only by adequate spectroscopy and/or photometry to provide a determination of stellar metallicity and temperature for a sufficient sample of stars of luminosities at and above an old main-sequence turnoff.

description: In crystal engineering and medicinal chemistry, cocrystals have enormous applications. Hydrochlorothiazide (HTZ) is found to form cocrystals with picolinic acid (HCP1), pyrazinamide (HPP2) and isonicotinic acid (HIP3). In order to predict energy properties and model potential charge transfer between cocrystal constituents, FMOs energies are used. The frontier molecular orbital analysis reveals the cocrystal’s chemical reactivity and bioactivity. MEP displays the different reactive surfaces in the cocrystals, which is very important when deciding on different biological activities. HCP1, HPP2 and HIP3 have different intermolecular interactions, most of the bonds between atoms are covalent and some of the intramolecular interactions are strong ionic or weak ionic. The non-covalent interactions and identical patterns in the covalent character of weak interactions in title molecules are supported by ELF and LOL. From the MD simulation, the complex structure formed by the HIP3 compound with Mpro was more stable and lower RMSD values than HCP1 and HPP2. The ligands formed strong interactions at SARS-Cov-2 Mpro possible binding sites.

Line ratios suggest AGN-photoionization for the systemic gas, and shock+precursor ionization for a second, spatially-unresolved, nuclear component blueshifted by 990 km/s. The gas in IRAS F23060+0505 is in dipolar rotation but with an asymmetric rotation curve and an increased FWHM on one side; an asymmetry to the narrow-line profiles is attributed to a spatially-resolved outflow, and shock+precursor ionization is dominant. At lower luminosity, IRAS F01217+0122 has a featureless velocity field with a high FWHM, an AGN-like emission-line spectrum and a ~1 Gyr old stellar population. IRAS F01003-2238 has a dipolar velocity field and an HII-region emission-line spectrum with a strong blue continuum which can be reproduced with ~10^7 O5 stars, sufficient to account for the bolometric luminosity of the entire galaxy. This diversity is accommodated within the merger-driven evolutionary scenario for ULIRGs: the merger status is assessed from the kinematics in a way which is consistent with the colour and morphology of the galaxy, or with the inferred age of the stellar population and the dominance of the AGN.

description: Benign prostatic hyperplasia (BPH) is a common disorder in men aged over 60 years and significantly contributes to the distressing lower urinary tract symptoms. Cucurbitacins are triterpene derivatives with diverse medicinal uses including prostate diseases. Cucurbitacin E glucoside was evaluated against testosterone-induced prostatic hyperplasia in mice. Our data indicate that it significantly inhibited the increase in prostate weight and prostate index. The compound ameliorated histopathological changes in prostatic architecture and inhibited the increase in glandular epithelial length induced by testosterone. These results were confirmed by decreased expression of cyclin D1 in prostatic tissues compared to those obtained from the testosterone-alone group. Also, it showed significant antioxidant activity as evidenced by inhibiting lipid peroxides accumulation, glutathione depletion and superoxide exhaustion. Further, it exhibited anti-inflammatory activity as it decreased cyclooxygenase-2 and interleukin-1β protein expression in prostatic tissues. Masson's trichrome staining of prostate sections indicated obvious antifibrotic activity that was supported by decreased α-smooth muscle actin expression. In conclusion, Cucurbitacin E glucoside inhibits testosterone-induced experimental BPH in mice due to, at least partly, its antiproliferative, antioxidant, anti-inflammatory, and antifibrotic effects.

description: Baryogenesis at the electroweak phase transition may take place through CP-violating reflections of quarks from expanding bubbles of the broken symmetry phase. We formulate and approximately solve the transport equations for the reflected quark asymmetries. The results are comparable to a previous Monte Carlo calculation and allow for analytic estimates of the baryon asymmetry $ΔB$ when the bubble walls have a small velocity. Our method predicts no velocity-dependence for $ΔB$ in the small $v$ limit, unlike results obtained from a simplified treatment based on the diffusion equation.

description: Natural compounds are widely explored in industries, as a lead compound. Evaluating their toxicity is of utmost importance, as they may cause other side effects. The major hassles in evaluating the toxicity of compounds through in vivo and in vitro methods such as time, money, workforce, and use of animal models can be overcome by computational methods. Quantitative structure–activity relationship (QSAR) models predict the toxicity from the structure of a compound. In the present study, the methanolic extracts of three plants, namely, Carissa carandas, Canthium angustifolium, and Epiphyllum oxypetalum, were subjected to Gas Chromatography-Mass Spectrometry (GC-MS), in which 27 different compounds were identified. The compounds were evaluated for their toxicity through QSAR-Toxicity Estimation Software Tool (TEST) against multispecies – Daphnia magna, Pimephales promelas, Tetrahymena pyriformis, and rat (Oral). The study revealed that the order of toxicity of the natural compounds was D. magna > T. pyriformis > P. promelas > Rat (Oral). All the compounds were non-bioaccummulative, while most of them were developmental toxicants. Only one compound (Dasycarpidan-1-methanol, acetate (ester)) was a mutagen. Further studies of the compounds on in vivo models are recommended after in silico analysis, for exploration in different industries.
Anisotropic inverse Compton scattering from the trans-relativistic to the ultra-relativistic regime and application to the radio galaxies

description: The problem of the anisotropic Inverse Compton scattering between a monochromatic photon beam and relativistic electrons is revisited and formally solved without approximations. Solutions are given for the single scattering with an electron beam and with a population of electrons isotropically distributed, under the assumption that the energy distribution of the relativistic particles follows a simple power law as it is the case in many astrophysical applications. Both the Thomson approximation and the Klein-Nishina regime are considered for the scattering of an unpolarized photon beam. The equations are obtained without the ultra-relativistic approximation and are compared with the ultra-relativistic solutions given in the literature. The main characteristics of the power distribution and spectra of the scattered radiation are discussed for relevant examples. In the Thomson case for an isotropic electron population simple formulae holding down to mildly-relativistic energies are given. As an application the formulae of the anisotropic inverse Compton scattering are used to predict the properties of the X and $γ$-ray spectra from the radio lobes of strong FR II radio galaxies due to the interaction of the relativistic electrons with the incoming photons from the nucleus. The dependence of the emitted power on the relativistic electron energy distribution and on its evolution with time is discussed.

description: We introduce high-energy limits which allow us to derive recursion relations fixing the various couplings of Lagrangians of two-dimensional relativistic quantum field theories with no tree-level particle production in a very straightforward way. The sine-Gordon model, the Bullough-Dodd theory, Toda theories of various kinds and the U(N) non-linear sigma model can all be rediscovered in this way. The results here were the outcome of our explorations at the 2017 Perimeter Institute Winter School.

description: We study a simple extension of Linde's hybrid inflation model, with the inflaton mass term replaced by the most general renormalizable potential for $ϕ$. The unprocessed power spectrum of density perturbations can have two minima and one maximum, roughly corresponding to two steep regions separated by a somewhat flat region in $V(ϕ)$. In the examples studied here, sufficient amount of inflation and normalization to COBE require a vacuum scale of $10^{16}$ GeV and a $ϕ$ mass of $10^{13}$ GeV. Depending on the initial value of $ϕ$, our model can give either less ($\sim n<1$) or more ($\sim n>1$) power on small scales compared to the scale-invariant spectrum ($n=1$), given the normalization to COBE.

description: Jump landing is a common situation leading to knee injuries involving the anterior cruciate ligament (ACL) in sports. Although neuromuscular control is considered as a key injury risk factor, there is a lack of knowledge regarding optimum control strategies that reduce ACL forces during jump landing. In the present study, a musculoskeletal model-based computational approach is presented that allows identifying neuromuscular control patterns that minimize ACL forces during jump landing. The approach is demonstrated for a jump landing maneuver in downhill skiing, which is one out of three main injury mechanisms in competitive skiing.

description: In this theoretical study, we establish a correlation between the neutron skin thickness and the nuclear symmetry energy for the even$-$even isotopes of Fe, Ni, Zn, Ge, Se and Kr within the framework of the axially deformed self-consistent relativistic mean field for the non-linear NL3$^*$ and density-dependent DD-ME1 interactions. The coherent density functional method is used to formulate the symmetry energy, the neutron pressure and the curvature of finite nuclei as a function of the nuclear radius. We have performed broad studies for the mass dependence on the symmetry energy in terms of the neutron-proton asymmetry for mass 70 $\leq$ A $\leq$ 96. From this analysis, we found a notable signature of a shell closure at $N$ = 50 in the isotopic chains of Fe, Ni, Zn, Ge, Se and Kr nuclei. The present study reveals an interrelationship between the characteristics of infinite nuclear matter and the neutron skin thickness of finite nuclei

description: This study aims to evaluate the mechanical performance of custom 3D-printed titanium plates in the treatment of distal humerus fractures. Rigidity of four plating configurations were investigated by finite element analysis. The results reveal that implementation of custom designs with minimal screw holes, lateral-medial linking screw and lateral brim could significantly improve stiffness and consequently leads to better biomechanical stability as compared to standard osteosynthesis design. Biomechanical testing was also performed to validate practical usability. The results confirm that newly designed custom plates fabricated by selective laser melting is a possible alternative for the treatment of distal humerus fracture.
