Two-photon transitions in primordial hydrogen recombination
Creators: name: Hirata, Christopher M.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The subject of cosmological hydrogen recombination has received much attention recently because of its importance to predictions for and cosmological constraints from CMB observations. While the central role of the two-photon decay 2s->1s has been recognized for many decades, high-precision calculations require us to consider two-photon decays from the higher states ns,nd->1s (n>=3). Simple attempts to include these processes in recombination calculations have suffered from physical problems associated with sequences of one-photon decays, e.g. 3d->2p->1s, that technically also produce two photons. These correspond to resonances in the two-photon spectrum that are optically thick, necessitating a radiative transfer calculation. We derive the appropriate equations, develop a numerical code to solve them, and verify the results by finding agreement with analytic approximations to the radiative transfer equation. The related processes of Raman scattering and two-photon recombination are included using similar machinery. Our results show that early in recombination the two-photon decays act to speed up recombination, reducing the free electron abundance by 1.3% relative to the standard calculation at z=1300. However we find that some photons between Ly-alpha and Ly-beta are produced, mainly by 3d->1s two-photon decay and 2s->1s Raman scattering. At later times these photons redshift down to Ly-alpha, excite hydrogen atoms, and act to slow recombination. Thus the free electron abundance is increased by 1.3% relative to the standard calculation at z=900. The implied correction to the CMB power spectrum is neligible for the recently released WMAP and ACBAR data, but at Fisher matrix level will be 7 sigma for Planck. [ABRIDGED]

Characterizing Intracellular Localization and Chromatin Remodeling Role of CHD6 in Human Fetal Development and in Glioblastoma
Creators: name: Tsankova, Nadejda

Publisher: name: Columbia Undergraduate Science Journal
Year: 2016

description: CHD6, a member of the CHD family of DNA-binding, chromatin-modifying proteins, has been shown to be upregulated in glioblastoma. Using immunofluorescence the intracellular region to which CHD6 localizes can be determined. Through the use of chromatin Immunoprecipitation (ChIP), candidate genomic loci enriched for CHD6 can be determined. Immunofluorescence and ChIP results for CHD6 using a current protocol are presented. Notably, immunofluorescence of fetal germinal matrix and adult subventricular zone showed principally cytoplasmic localization of CHD6, contrary to expectation. CHD6 ChIP showed partial enrichment in certain genes of possible significance to glioblastoma in fetal tissue relative to the positive control. A higher sample size is needed to test and evaluate the significance of these findings. The results presented here reveal new insights into the changes in the epigenetic landscape contributing to glioblastoma and the manipulation of CHD6 expression could be considered for treating specific incidents of glioblastoma.

Abstract
Spherically symmetric model atmospheres for late-type giant stars
Creators: name: Bennett, Philip Desmond
Publisher: name: University of British Columbia
Year: 2011

description: The ATHENA computer code has been developed to model the extended atmospheres of late-type giant and supergiant stars. The atmospheres are assumed to be static, spherically symmetric and in radiative and hydrostatic equilibrium. Molecular line blanketing (for now) is handled using the simplifying assumption of mean opacities. The complete linearization method of Auer and Mihalas [7], adapted to spherical geometry, is used to solve the model system. The radiative transfer is solved by using variable Eddington factors to close the system of moment transfer equations, and the entire system of transfer equations plus constraints is solved efficiently by arrangement into the Rybicki [83] block matrix form. The variable Eddington factors are calculated from the full angle-dependent formal solution of the radiative transfer problem using the impact parameter method of Hummer, Kunasz and Kunasz [47]. We were guided by the work of Mihalas and Hummer [72] in their development of extended models of O stars, but our method differs in the choice of the independent variable. The radius depth scale used by Mihalas and Hummer was found to fail because of the strongly temperature-dependent opacities of late-type atmospheres. Instead, we were able to achieve an exact linearization of the radius. This permitted the use of the numerically well-behaved column mass or optical depth scales. The resulting formulation is analogous to the plane-parallel complete linearization method and reduces to this method in the compact atmosphere limit. Models of M giants were calculated for T[formula omitted] = 3000K and 3500K with opacities of the CN, TiO and H₂0 molecules included, and the results were in general agreement with other published spherical models. These models were calculated assuming radiative equilibrium. The importance of convective energy transport was estimated by calculating the convective flux that would result from the temperature structure of the models. The standard local mixing length theory was used for this purpose. Convection was found to be important only at depths with Ƭ[formula omitted] > 15 for the low gravity models with log g = 0, but significant out to Ƭ[formula omitted] ~ 1 at the most transparent frequencies for the higher gravity models with log g = 2. Thus, the temperature structure of the surface layers and the emergent flux for the log g = 0 models should be accurately modelled but the emergent flux for the log g = 2 models may be in error by up to 5% at the most transparent frequencies.

Bethany Klein. As Heard on TV: Popular Music in Advertising
Creators: name: Pinson, Heather
Publisher: name: Current Musicology
Year: 2011

description: Bethany Klein’s As Heard on TV’ Popular Music in Advertising provides an introduction into the recent history of popular music as a marketing tool in television commercials and assembles a chronological history of the most well-known usages of popular music utilized in advertising campaigns. Klein includes a series of case studies throughout this book, such as the Beatles’s “Revolution,” used by Nike; Iggy Pop’s lyrically salacious “Lust for Life;’ used by Royal Caribbean Cruise; and Creedence Clearwater Revival’s song “Fortunate Son,” used in a Wrangler’s ad. As a media industries scholar at the Institute of Communications Studies at the University of Leeds, Klein’s focus is on the commercialization of popular music and its involvement in other media. As such, her main goal is to create a chronological history of the significant collaborations between musicians and corporate businesses and to provide insight into the decisions, reactions, and outcomes of popular music licensers and advertising industry representatives. Framed in the rhetoric of market communication and media research, As Heard on TVs broad scope makes it best suited for an introduction to intersections between the music industry, advertising, business practices, and popular culture. As Heard on TV explores the relationships between music executives, musicians, and music business practices through various modes of communication such as e-mails, written contracts, and verbal exchanges. For each commercial discussed, Klein provides any written or verbal accounts stemming from the advertising agency’s inquiry into the potential use of a band’s song to the final acquisition of the music license. Much of the author’s information comes from newspapers, online magazines, magazines, industry journals, scholarly books, and interviews that Klein conducted. Many of these interviews were with music supervisors, musicians, advertising “creatives;’ and licensing managers. These individuals serve as the basis for much of her insight into the business side of music making and is an examination of the frayed relationship between marketing executives, licensers, and the music supervisors who must create a business arrangement between the band and the product’s brand name. While Klein acknowledges that these interviews are not ethnographic in scope or nature, as have been studies of American culture such as Tia DeNora’s Music in Everyday Life (2000), these interviews do offer a unique insight into the advertising industry.

description: For a sample of 43 nearby, late-type galaxies, we have investigated the radial variation of both the current star formation rate and the dust-induced UV light attenuation. To do this we have cross-correlated IRAS images and GALEX observations for each of these galaxies, and compiled observations of the gas (CO and HI) and metal-abundance gradients found in the literature. We find that attenuation correlates with metallicity. We then use the UV profiles, corrected for attenuation, to study several variants of the Schmidt law and conclude that our results are compatible with a simple law similar to the one of Kennicutt but extending smoothly to lower surface densities, but with considerable scatter. We do not detect an abrupt break in the UV light at the threshold radius derived from H-alpha data (at which the H-alpha profile shows a break and beyond which only a few HII regions are usually found). We interpret the H-alpha sudden break not as a change in the star formation regime (as often suggested) but as the vanishingly small number of ionizing stars corresponding to low levels of star formation.

description: We explore parton collisional effects on the conversion of geometry eccentricities into azimuthal anisotropies in Pb+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV using a multi-phase transport model. The initial eccentricity $\varepsilon_{n}$ (n = 2,3) and flow harmonics $v_{n}$ (n = 2,3) are investigated as a function of the number of parton collisions ($N_{coll}$) during the source evolution of partonic phase. It is found that partonic collisions leads to generate elliptic flow $v_{2}$ and triangular flow $v_{3}$ in Pb+Pb collisions. On the other hand, partonic collisions also result in an evolution of the eccentricity of geometry. The collisional effect on the flow conversion efficiency is therefore studied. We find that the partons with larger $N_{coll}$ show a lower flow conversion efficiency, which reflect differential behaviors with respect to $N_{coll}$. It provides an additional insight into the dynamics of the space-momentum transformation during the QGP evolution from a transport model point of view.

Optical Characterization of Potential Dampening in Dendritic Spine Electrophysiology

Publisher: name: Columbia Undergraduate Science Journal
Year: 2016

description: This study aims to quantitatively characterize the electrophysiology of the dendritic spine as compared to that of its adjacent dendritic shaft, by imaging artificially induced back-propagating action potentials using a variety of different genetically encoded voltage indicators. We performed whole cell patch clamp and current injection recordings with simultaneous voltage imaging of neonatal mouse hippocampal neurons, which were transfected to express ‘ArcLight’ or one of two variants of ‘Archaerhodopsin 3 (Arch)’ known as ‘QuasAr1’ and ‘QuasAr2’. With ArcLight, we coupled electrophysiological current injection recordings with fluorescence imaging and compared the individual peak fluorescence change () value of each spine with the peak value of its adjacent dendritic shaft in response to induced back-propagating action potentials. The results from ArcLight do not indicate a statistically significant dampening in membrane potential from the dendrite shaft across an adjacent spine, but do suggest a difference in membrane potential fluctuations between long pulse (100msec) and short pulse (20msec) current injections. With Arch, we quantified the values from current injection recordings and voltage imaging sessions of neuronal soma for ‘QuasAr1’ and ‘QuasAr2’. Preliminary current injection and soma imaging results initially exhibited negligible signal-to-noise ratios of in response to induced action potentials, possibly due to technical maladjustments. A subsequent, more general characterization of Arch using voltage clamp and voltage step manipulations with QuasAr1 at different laser intensities indicates that QuasAr1 shows large changes in fluorescence at much weaker laser intensities (~10 mW) than was used for aforementioned current injection voltage imaging (~110 mW). We intend to further optimize and apply QuasAr1 and QuasAr2 to spine imaging, and subsequently investigate the difference in peak values for different current injection pulse durations as suggested by ArcLight imaging data.

description: Early observations of T Tauri stars suggested that stars with evidence of circumstellar accretion disks rotated slower than stars without such evidence, but more recent results are not as clear. Near-IR circumstellar disk indicators, though the most widely available, are subject to uncertainties that can result from inner disk holes and/or the system inclination. Mid-infrared observations are less sensitive to such effects, but until now, these observations have been difficult to obtain. The Spitzer Space Telescope now easily enables mid-infrared measurements of large samples of PMS stars covering a broad mass range in nearby star-forming regions. Megeath and collaborators surveyed the Orion Molecular Clouds (~1 Myr) with the IRAC instrument (3.6, 4.5, 5.8, 8 microns) as part of a joint IRAC and MIPS GTO program. We examine the relationship between rotation and Spitzer mid-IR fluxes for ~900 stars in Orion for stars between 3 and 0.1 Msun. We find in these Spitzer data the clearest indication to date that stars with longer periods are more likely than those with short periods to have IR excesses suggestive of disks.

description: This study concerns the two-body scattering of particles in a one-dimensional periodic potential. A convenient ansatz allows for the separation of center-of-mass and relative motion, leading to a discrete Schrödinger equation in the relative motion that resembles a tight-binding model. A lattice Green's function is used to develop the Lippmann-Schwinger equation, and ultimately derive a multi-band scattering K-matrix which is described in detail in the two-band approximation. Two distinct scattering lengths are defined according the limits of zero relative quasi-momentum at the top and bottom edges of the two-body collision band. Scattering resonances occur in the collision band when the energy is coincident with a bound state attached to another higher or lower band. Notably, repulsive on-site interactions in an energetically closed lower band lead to collision resonances in an excited band.

This result is inconsistent with the no-mixing hypothesis with a significance of 3.9 standard deviations. We measure R_D, the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates, to be [0.303 +- 0.016 (stat.) +- 0.010 (syst.)]%. We find no evidence for \CP violation.

We take into account tree level and loop diagrams coming from the axial-vector decay into a vector and a pseudoscalar meson. We find a large span for the values of the radiative widths of the different axial-vector mesons. In particular, we evaluate the radiative decay into $K γ$ of the two $K_1(1270)$ states, recently claimed theoretically, and discuss the experimental values quoted so far on the assumption of only one state.
Effects of Invasive Plant Leaf Litter on a Lake Ecosystem
Creators: name: Bhardwaj, Amar A.
Publisher: name: Columbia Undergraduate Science Journal
Year: 2017

description: Invasive plants are introduced into foreign ecosystems and proliferate easily. These plants often have no natural consumers in their new environment, allowing them to outcompete neighboring native plants, causing a plethora of detriments. This research aimed to help solve a rarely investigated aspect of this problem: the effect of invasive plant leaf litter on lake ecosystem dynamics. It was predicted that invasive leaf litter would have more adverse effects on a lake than native litter, because overwhelming evidence in the literature indicates the harm of invasive plants. This was tested with four groups of mesocosms corresponding to four leaf litter treatments: a native mix of red maple and American beech litter, a monoculture of invasive common reed leaf litter, an invasive monoculture of Japanese knotweed litter, and a mixture of litter from all four species. Using repeated measures analysis of variance statistical tests, each treatment was compared in its effects on the lake ecosystem’s phosphate concentration, nitrate concentration, algae growth, mosquito development, pH, dissolved oxygen concentration, and water conductivity. The common reed leaf litter treatment resulted in the highest nitrate, phosphate, and oxygen levels, leading to the conclusion that this leaf litter can potentially cause eutrophication in lakes. Additionally, Japanese knotweed resulted in the highest conductivity and lowest oxygen levels, showing its leaf litter has the fastest breakdown. The rapidity of this breakdown poses a harm to a lake as adjustment to rapid changes places various stresses on ecosystems. These discoveries can be implemented in lake conservation to more effectively maintain a healthy ecosystem

description: Hadron production at high-$p_T$ displays a strong suppression pattern in a wide rapidity region in heavy ion collisions at RHIC energies. This finding indicates the presence of strong final state effects for both transversally and longitudinally traveling partons, namely induced energy loss. We have developed a perturbative QCD based model to describe hadron production in $pp$ collision, which can be combined with the Glauber -- Gribov model to describe hadron production in heavy ion collisions. Investigating $AuAu$ and $CuCu$ collisions at energy $\sqrt{s}=200$ $A$GeV at mid-rapidity, we find the opacity of the strongly interacting hot matter to be proportional to the participant nucleon number. Considering forward rapidities, the suppression pattern indicates the formation of a longitudinally contracted dense deconfined zone in central heavy ion collisions. We determine parameters for the initial geometry from the existing data.

The distribution of the fortunes of players not yet eliminated is found to be independent of time during most of the tournament, and reproduces accurately data obtained from Internet tournaments and world championship events. This model also makes the connection between poker and the persistence problem widely studied in physics, as well as some recent physical models of biological evolution, and extreme value statistics.

description: Objectives. The aim of this study was to identify major determinants for neck and lower back pain (LBP) among office workers of different ages. Methods. Computer workers (N = 2000) responded to a questionnaire on demographics, musculoskeletal disorders (MSDs), lifestyle characteristics, ergonomics of computer work and psychosocial and physical job characteristics. Results. Over 48% of respondents complained of MSDs last year, in particular neck pain and LBP. The results of logistic regression analysis revealed that prolonged computer time (odds ratio [OR] 1.92) and increased job demands (OR 1.06) were likely to increase the risk of neck pain, while social support (OR 0.96) and the use of seat-plate height adjustment (OR 0.64) would help to reduce the risk. Risk factors for LBP included smoking more than 14 cigarettes a day (OR 2.21), long hours spent working with a computer (OR 1.94), increased physical exertion at work (OR 1.29), increased work demands (OR 1.03) and older age (OR 1.03). Conclusions. The most effective way to eliminate MSD hazards in the workplace is to develop health programmes aimed at advocating healthy lifestyle behaviours and raising workers’ awareness of workstation ergonomics and work organization, especially for women and older workers.

description: It is known that the Standard Model, being a spontaneously broken gauge theory, violates the decoupling theorem. In practice, this means that amplitudes for low-energy processes grow without limit as the mass of fermions or scalars is made large. As a result of the recent determination of a lower bound of 90 GeV on the mass of the top quark and the general expectation of a large mass for the Higgs boson, this effect could lead to large higher order corrections to the observables of the theory. In this spirit, we calculate the two-loop corrections to the [Beta] - [|Beta] mixing amplitude in the two limits of a very large top quark mass or a very large Higgs mass. Analytical expressions are obtained for the leading terms. The results are found to be much smaller than what one would naively expect.

Subjects: Work-life balance, Work-family Conflict, Family work Conflict, Occupational Health, Physical health, and psychological health.

description: Abstract

Background: Work-life balance is a central issue affecting the health of employees. The success of a person as an employee as well as a social being is determined by his/her work-life balance. Work-life balance and occupational health issues are two major concerns for researchers due to their impact on the stress level, quality of life, productivity, and turnover of employees. Aim & Objectives: To explore the challenges faced by employees in a service organization about maintaining work-life balance and give suggestions for the same.  Methods: A descriptive research design was utilized for the study. The essential information was gathered through an organized survey. A sample of 150 representatives of the health care profession of Government medical college & hospital Cuddalore was chosen for the research in the year 2022. Data was collected through a convenient sampling method. The questions focused on various facilities available in the organization to balance work and family life and the effective usage of such facilities. Work-life balance was assessed based on work-family conflict and family work conflict. Results: Occupational health issues were assessed based on two factors i.e., psychological and physical health issues. The result shows that employees face issues in balancing their work and family life. The need for childcare facilities and financial support for elderly care are highlighted in the study. This study reveals that respondents have work-life balance issues where work-family conflict was found to be higher than family-work conflict. Conclusion: Physical health issues are a major concern for them than psychological health issues. This study also reveals that there was an association between work-life balance and psychological health issues.

description: Atoms with a large scattering length have universal low-energy properties that do not depend on the details of their structure or their interactions at short distances. In the 2-atom sector, the universal properties are familiar and depend only on the scattering length. In the 3-atom sector for identical bosons, the universal properties include the existence of a sequence of shallow triatomic molecules called Efimov trimers and log-periodic dependence of scattering observables on the energy and the scattering length. In this review, we summarize the universal results that are currently known. We also summarize the experimental information that is currently available with an emphasis on 3-atom loss processes.

description: n this paper we consider polynomial cointegrating relationships among stationary processes with long range dependence. We express the regression functions in terms of Hermite polynomials and we consider a form of spectral regression around frequency zero. For these estimates, we establish consistency by means of a more general result on continuously averaged estimates of the spectral density matrix at frequency zero

Q-balls in Maxwell-Chern-Simons theory

description: We examine the energetics of Q-balls in Maxwell-Chern-Simons theory in two space dimensions. Whereas gauged Q-balls are unallowed in this dimension in the absence of a Chern-Simons term due to a divergent electromagnetic energy, the addition of a Chern-Simons term introduces a gauge field mass and renders finite the otherwise-divergent electromagnetic energy of the Q-ball. Similar to the case of gauged Q-balls, Maxwell-Chern-Simons Q-balls have a maximal charge. The properties of these solitons are studied as a function of the parameters of the model considered, using a numerical technique known as relaxation. The results are compared to expectations based on qualitative arguments.

description: We present a new version of the Ogre open source Python package with the capability to perform structure prediction of epitaxial inorganic interfaces by lattice and surface matching. In the lattice matching step a scan over combinations of substrate and film Miller indices is performed to identify the domain-matched interfaces with the lowest mismatch. Subsequently, surface matching is conducted by Bayesian optimization to find the optimal interfacial distance and in-plane registry between the substrate and film. For the objective function, a geometric score function is proposed, based on the overlap and empty space between atomic spheres at the interface. The score function reproduces the results of density functional theory (DFT) at a fraction of the computational cost. The optimized interfaces are pre-ranked using a score function based on the similarity of the atomic environment at the interface to the bulk environment. Final ranking of the top candidate structures is performed with DFT. Ogre streamlines DFT calculations of interface energies and electronic properties by automating the construction of interface models. The application of Ogre is demonstrated for two interfaces of interest for quantum computing and spintronics, Al/InAs and Fe/InSb.

description: We consider the problem of optical tomographic imaging in the mesoscopic regime where the photon mean free path is of order of the system size. Within the accuracy of the single-scattering approximation to the radiative transport equation, we show that it is possible to recover the extinction coefficient of an inhomogeneous medium from angularly-resolved measurements. Applications to biomedical imaging are described and illustrated with numerical simulations.

Music for the Last Supper: The Dramatic Significance of Mozart’s Musical Quotations in the Tafelmusik of Don Giovanni
Creators: name: Chong, Nicholas Junkai
Publisher: name: Current Musicology
Year: 2011

description: In the Act II finale of Mozart’s Don Giovanni, as the title character enjoys his dinner, a domestic wind band, called a Harmonie in Mozart’s time, plays some Tafelmusik – music intended to accompany a meal. The Tafelmusik that Mozart chose for Don Giovanni’s last supper consists of melodies quoted from three contemporaneous opere buJfe (Example 1): Vincente Martin y Soler’s Una cos a rara (1786), Giuseppe Sarti’s Fra i due litiganti il terzo gode (1782), and Mozart’s own The Marriage of Figaro (1786). Such musical quotation is a specific type of allusion. As Christopher Reynolds has pointed out, an allusion is not simply a “reference to another work made by means of a resemblance;’ but must be intentional; since “motivic possibilities are finite;’ unintended similarities between two works are bound to occur. Quotation employs an especially high degree of resemblance to the source being alluded to; in the case of the Tafelmusik, whole melodies are reproduced from other operas, not just smaller motives. “Quotations,” Reynolds writes, “are neither more nor less meaningful than less exact references-only a different degree of artistic appropriation.” I would go further and argue that quotations, in comparison to less exact forms of allusion, demonstrate intentionality. Leaving aside situations where there exists documentary proof of a composer’s intentions, it is always possible to argue that resemblances between two pieces are unintended. With quotations, however, this possibility is greatly diminished because the reference is much more exact. In the Tafelmusik, not only are the melodies unmistakable quotations from other operas; Mozart even has Leporello announce them as such to the audience. There can thus be no doubt that Mozart intended these quotations to be heard and easily identified. As the quotations from Martin’s and Sarti’s operas begin, Leporello announces their titles. “Bravi! ‘Cosa raraT’ he cries (mm. 53-54), then later “Evvivano i ‘LitigantiT’ (mm. 123-25). Finally, Leporello hears the quotation from Figaro-the tune of Figaro’s aria “Non pili andrai:’ This time, instead of announcing the title of Mozart’s earlier opera, he sings, “Questa poi la conosco pur troppo” (mm. 164-66) “This one, then, I know only too well”). At the Prague premiere of Don Giovanni, this line would have had a special significance for the local audience, for Felice Ponziani, the baritone singing Leporello, had also sung the role of Figaro-and “Non pili andrai” – in Prague the year before.

description: Electron field emission characteristics of individual multiwalled carbon nanotubes have been investigated by a piezoelectric nanomanipulation system operating inside a scanning electron microscopy chamber. The experimental setup ensures a high control capability on the geometric parameters of the field emission system (CNT length, diameter and anode-cathode distance). For several multiwalled carbon nanotubes, reproducible and quite stable emission current behaviour has been obtained with a dependence on the applied voltage well described by a series resistance modified Fowler-Nordheim model. A turn-on field of about 30 V/um and a field enhancement factor of around 100 at a cathode-anode distance of the order of 1 um have been evaluated. Finally, the effect of selective electron beam irradiation on the nanotube field emission capabilities has been extensively investigated.
