description: We present a quantum field theoretical method for the characterization of disordered complex media with short laser pulses in an optical coherence tomography setup (OCT). We solve this scheme of coherent transport in space and time with weighted essentially nonoscillatory methods (WENO). WENO is preferentially used for the determination of highly nonlinear and discontinuous processes including interference effects and phase transitions like Anderson localization of light. The theory determines spatiotemporal characteristics of the scattering mean free path and the transmission cross section that are directly measurable in time-of-flight (ToF) and pump-probe experiments. The results are a measure of the coherence of multiple scattering photons in passive as well as in optically soft random media. Our theoretical results of ToF are instructive in spectral regions where material characteristics such as the scattering mean free path and the diffusion coefficient are methodologically almost insensitive to gain or absorption and to higher-order nonlinear effects. Our method is applicable to OCT and other advanced spectroscopy setups including samples of strongly scattering mono- and polydisperse complex nano- and microresonators.

description: We present the results of an extensive search for periodic and irregular variable pre-main sequence (PMS) stars in the young (2-4 Myr) open cluster NGC 2664, based on photometric monitoring using the Wide Field Imager (WFI) on the 2.2m telescope on La Silla (Chile). In total, about 10600 stars with I_c magnitudes between 9.8mag and 21mag have been monitored in our 34x33 arcmin field. Time series data were obtained in the I_c band in 44 nights between Dec. 2000 and March 2001; altogether we obtained 88 data points per star. Using two different time series analysis techniques (Scargle and CLEAN) we found 543 periodically variable stars with periods between 0.2 days and 15 days. Also, 484 irregular variable stars were identified using a chi-squared-test. In addition we have carried out nearly simultaneous observations in V, R_c and a narrow-band Halpha filter. The photometric data enable us to reject background and foreground stars from our sample of variable stars according to their location in the I_c vs. (R_c-I_c) colour-magnitude and (R_c-Halpha) vs. (R_c-I_c) colour-colour diagram. We could in the end identify 405 periodically variable and 184 irregular variable PMS stars as cluster members using these two different tests. In addition 35 PMS stars for which no significant variablilty were detected could be identified as members using an Halpha emission index criterion. This yields to a total of 624 PMS stars in NGC 2264, of which only 182 were known before. Most of the newly found PMS stars are fainter than I_c = 16 and of late spectral type (>M2). (abridged)

description: Controllable, partially isolated few level systems in semiconductors have recently gained multidisciplinary attention due to their widespread nanoscale sensing and quantum technology applications. Quantitative simulation of the dynamics and related applications of such systems is a challenging theoretical task that requires faithful description not only the few level systems but also their local environments. Here, we develop a method that can describe relevant relaxation processes induced by a dilute bath of nuclear and electron spins. The method utilizes an extended Lindblad equation in the framework of cluster approximation of a central spin system. We demonstrate that the proposed method can accurately describe T$_1$ time of an exemplary solid-state point defect qubit system, in particular NV center in diamond, at various magnetic fields and strain.

description: Exact diagonalization results are reported for the lowest rotational band of N=6 electrons in strong magnetic fields in the range of high angular momenta 70 <= L <= 140 (covering the corresponding range of fractional filling factors 1/5 >= nu >= 1/9). A detailed comparison of energetic, spectral, and transport properties (specifically, magic angular momenta, radial electron densities, occupation number distributions, overlaps and total energies, and exponents of current-voltage power law) shows that the recently discovered rotating-electron-molecule wave functions [Phys. Rev. B 66, 115315 (2002)] provide a superior description compared to the composite-fermion/Jastrow-Laughlin ones.

Branch-entangled polariton pairs in planar microcavities and photonic wires

description: A scheme is proposed for the generation of branch-entangled pairs of microcavity polaritons through spontaneous inter-branch parametric scattering. Branch-entanglement is achievable when there are two twin processes, where the role of signal and idler can be exchanged between two different polariton branches. Branch-entanglement of polariton pairs can lead to the emission of frequency-entangled photon pairs out of the microcavity. In planar microcavities, the necessary phase-matching conditions are fulfilled for pumping of the upper polariton branch at an arbitrary in-plane wave-vector. The important role of nonlinear losses due to pair scattering into high-momentum exciton states is evaluated. The results show that the lack of protection of the pump polaritons in the upper branch is critical. In photonic wires, branch-entanglement of one-dimensional polaritons is achievable when the pump excites a lower polariton sub-branch at normal incidence, providing protection from the exciton reservoir.

description: Variational wave functions based on a Margenau-Brink cluster model with short range and state dependent correlations, and angular momentum projection are obtained for some nuclei with $12 \leq A \leq 16$. The calculations have been carried out starting from the nucleon-nucleon interaction by using the Variational Monte Carlo method. The configuration used consists of three alpha clusters located at the apexes of an equilateral triangle, and an additional cluster, not necessarily of alpha type, forming a tetrahedron. This cluster is located at the top of its height. Short-range and state dependent correlations are included by means of a central Jastrow factor and a linear operatorial correlation factor respectively. Angular momentum projection is performed by using the Peierls-Yoccoz operators. Optimal structures are obtained for all the nuclei studied. Some aspects of our methodology have been tested by comparing with previous calculations carried out without short range correlations. The binding energy, the root mean square radius, and the one- and two-body densities are reported. The effects of correlations on both the energy and the nucleon distribution are analyzed systematically.

description: In a recent letter we suggested a natural generalization of the flat-space spinor-helicity formalism in four dimensions to anti-de Sitter space. In the present paper we give some technical details that were left implicit previously. For lower-spin fields we also derive potentials associated with the previously found plane wave solutions for field strengths. We then employ these potentials to evaluate some three-point amplitudes. This analysis illustrates a typical computation of an amplitude without internal lines in our formalism.

Absorbing phase transitions in a non-conserving sandpile model

description: We introduce and study a non-conserving sandpile model, the autonomously adapting sandpile (AAS) model, for which a site topples whenever it has two or more grains, distributing three or two grains randomly on its neighboring sites, respectively with probability $p$ and $(1-p)$. The toppling process is independent of the actual number of grains $z_i$ of the toppling site, as long as $z_i\ge2$. For a periodic lattice the model evolves into an inactive state for small $p$, with the number of active sites becoming stationary for larger values of $p$. In one and two dimensions we find that the absorbing phase transition occurs for $p_c\!\approx\!0.717$ and $p_c\!\approx\!0.275$. The symmetry of bipartite lattices allows states in which all active sites are located alternatingly on one of the two sublattices, A and B, respectively for even and odd times. We show that the AB-sublattice symmetry is spontaneously broken for the AAS model, an observation that holds also for the Manna model. One finds that a metastable AB-symmetry conserving state is transiently observable and that it has the potential to influence the width of the scaling regime, in particular in two dimensions. The AAS model mimics the behavior of integrate-and-fire neurons which propagate activity independently of the input received, as long as the threshold is crossed. Abstracting from regular lattices, one can identify sites with neurons and consider quenched networks of neurons connected to a fixed number $G$ of other neurons, with $G$ being drawn from a suitable distribution. The neuronal activity is then propagated to $G$ other neurons. The AAS model is hence well suited for theoretical studies of nearly critical brain dynamics. We also point out that the waiting-time distribution allows an avalanche-free experimental access to criticality.

description: We present a large and updated stellar evolution database for low-, intermediate- and high-mass stars in a wide metallicity range, suitable for studying Galactic and extragalactic simple and composite stellar populations using population synthesis techniques. The stellar mass range is between \sim0.5Mo and 10Mo with a fine mass spacing. The metallicity [Fe/H] comprises 10 values ranging from -2.27 to 0.40, with a scaled solar metal distribution. The initial He mass fraction ranges from Y=0.245, for the more metal-poor composition, up to 0.303 for the more metal-rich one, with Delta Y/Delta Z\sim 1.4. For each adopted chemical composition, the evolutionary models have been computed without and with overshooting from the Schwarzschild boundary of the convective cores during the central H-burning phase. The whole set of evolutionary models can be used to compute isochrones in a wide age range, from \sim30 Myr to \sim15Gyr. Both evolutionary tracks and isochrones are available in several observational planes, employing updated set of bolometric corrections and color-Te relations computed for this project. The number of points along the models and the resulting isochrones is selected in such a way that interpolation for intermediate metallicities not contained in the grid is straightforward. We compare our isochrones with results from different stellar evolution databases and perform some empirical tests for the reliability of our models. Since this work is devoted to scaled solar compositions, we focus our attention on the Galactic disk populations, employing multicolor photometry of unevolved field MS stars with precise Hipparcos parallaxes, well-studied open clusters and one eclipsing binary system with precise measurements of masses, radii and [Fe/H] of both components.

title: Enhancement of Favipiravir With Compound X in a Hamster Model of Yellow Fever Virus Infection
Creators: name: Stanger, Hunter
Publisher: name: Utah State University
Year: 2024

description: Yellow fever virus (YFV) has long been a worldwide health concern, and recent outbreaks in South America and Africa have resulted in significant mortality. There is currently an effective vaccine to prevent infection, but there are no currently developed antiviral drugs to treat patients that have already contracted the disease. Because of this, an effective antiviral is needed to combat unanticipated cases or emergence in areas that have previously been unaffected by this virus. A drug called favipiravir has shown promising results previously. This compound acts as a nucleoside analog to halt the replication of the virus and stop infection. However, the needed dosages of favipiravir are toxic in humans. A separate drug termed "Compound X" has shown potentiator activity by increasing the concentration of the active form of favipiravir in vitro. In this study, we administered suboptimal, non-toxic doses of favipiravir in combination with Compound X to determine this combination treatment's antiviral efficacy against YFV infection in an in-vivo, hamster model. Different doses of favipiravir alone, Compound X alone, a vehicle placebo drug, or both favipiravir and Compound X in tandem were administered twice daily for seven days. Mortality and weight change were recorded for the course of 21 days. Serum was collected on days four and six post infection and analyzed for serum virus titers as well as alanine aminotransferase (ALT) levels indicative of YFV infection. No significant difference was seen in serum viremia or ALT levels in any groups. However, there was a significant difference in weight change and mortality among the groups treated with the combination treatment. The combination treatment of Compound X with favipiravir was more effective than either drug alone at reducing weight loss and overall mortality in the groups treated. These results show promise for the future that these drugs may be used in combination to effectively treat YFV infection while avoiding toxicity in humans.

description: The lasing threshold of a random laser is computed numerically from a generic model. It is shown that spatial correlations of the disorder in the medium (i.e., dielectric constant) lead to an increase of the decay rates of the eigenmodes and of the lasing threshold. This is in conflict with predictions that such correlations should lower the threshold. While all results are derived for photonic systems, the computed decay rate distributions also apply to electronic systems.

description: The research is conducted with background that Macau government has had positive satisfaction rate from 1999 to 2018. According to Macau annual survey by HKU’s public polling survey released in December 2018, Macau government received with highest satisfaction rate of 75.8% in 2014 and 62.6% of Macau residents evaluate the policy of the Central Government on Macau after the Handover to be very good and quite good. 62% of Macau residents rated trust in the Beijing Government in 2018 with highest rate at 79.9% during the research period. The Macau’s GDP per capital recorded USD of USD 83,000 per capital in 2019 from USD15,000 in 1999 during the research period. Macau has no independence ranking on the league table the reporter without border ranking. The Article 27 of Macau Basic Law guarantees that Article 27 Macao residents shall have freedom of speech, of the press and of publication; freedom of association, of assembly, Of procession and of demonstration; and the right and freedom to form and join trade unions, and to strike. On 10th June 2019, in order to prevent the spread of rumours, fake news or misinformation during emergency situations, the Legislative Assembly (AL) 1st Standing Committee passed the Civil Protection Law which defines crimes against public security, order and peace in sudden incidents of public nature, with a previous draft predicting a possible prison sentence of up to three years for spreading false, unfounded and biased news. This paper aims to apply requirements used by the reporter without border for measurement of the editorial independence to obtain the perspective of Macau Journalists towards the degree of press freedom in Macau and whether the organizations they work for fulfill the press freedom as the intrinsic values of Psychological Contract on their employment contract after the passing of this law. 10 news workers from Macau local media organizations were interviewed anonymously for this research.

description: We report on non equilibrium field effect in insulating amorphous NbSi thin films having different Nb contents and thicknesses. The hallmark of an electron glass, namely the logarithmic growth of a memory dip in conductance versus gate voltage curves, is observed in all the films after a cooling from room temperature to 4.2 K. A very rich phenomenology is demonstrated. While the memory dip width is found to strongly vary with the film parameters, as was also observed in amorphous indium oxide films, screening lengths and temperature dependence of the dynamics are closer to what is observed in granular Al films. Our results demonstrate that the differentiation between continuous and discontinuous systems is not relevant to understand the discrepancies reported between various systems in the electron glass features. We suggest instead that they are not of fundamental nature and stem from differences in the protocols used and in the electrical inhomogeneity length scales within each material.

description: We report follow-up observations of a new white dwarf/red dwarf binary HS2237+8154, identified as a blue variable star from the Hamburg Quasar Survey. Ellipsoidal modulation observed in the R band as well as the Halpha radial velocity variations measured from time-resolved spectroscopy determine the orbital period to be Porb=178.10+-0.08min. The optical spectrum of HS2237+8154 is well described by a combination of a Teff=11500+-1500K white dwarf (assuming log g=8) and a dM3.5+-0.5 secondary star. The distance implied from the flux scaling factors of both stellar components is d=105+-25pc. Combining the constraints obtained from the radial velocity of the secondary and from the ellipsoidal modulation, we derive a binary inclination of i~50deg-70deg and stellar masses of Mwd=0.47-0.67Msun and Msec=0.2-0.4Msun. All observations imply that the secondary star must be nearly Roche-lobe filling. Consequently, HS2237+8154 may be either a pre-cataclysmic variable close to the start of mass transfer, or (considering its orbital period) a cataclysmic variable that terminated mass transfer and entered the period gap, or a hibernating nova.

description: We present the broad band analysis of two BeppoSAX observations of the Sy 1 Mkn509. In 2000 the source was in a typical flux state, F{2-10keV}=2.7x10^{-11}erg cm^{-2} s^{-1}, while in 1998 it was found in a high flux state, F{2-10keV}=5.7x10^{-11} erg cm^{-2} s^{-1}. A comparison between the two states shows a energy-dependent flux variation. A soft excess, a narrow iron line and a Compton reflection hump above 10 keV, are clearly apparent in the residuals after fitting the spectra with a simple power law. We tested two alternative models. In the first the iron line and the high energy bump are well reproduced by reprocessing in a cold and Compton thick material. The intensity of the iron line (also consistent with a Chandra measurement) as well as the normalization of the reflection hump are consistent with a constant in the two epochs: this, combined with the fact that the line is narrow as observed by Chandra, suggests a common origin from distant and optically thick matter. This model further requires a component to model the soft excess: the empirical choice of two black bodies accounts well for the excess in both observations, their combined strength was a factor about three higher in the high than in the low flux state defined above. However the relative contribution of the soft excess is higher in the low flux state. In the second model we attempted to reproduce all spectral features, except for the narrow cold line, with reflection from an ionized disc. This model is successful only in the high flux state,but it fails in the low flux state, when the soft excess is only partially accounted for. In either models, the slope of the power law is larger in the high than in the low flux state, in agreement with a behaviour known to be shared by several objects of the same type.

Grazie ai dati di archivio del Chandra X-ray Observatory della Nasa gli astronomi hanno rilevato per la prima volta un’emissione a raggi X di Urano. Oltre all’attesa dispersione della luce solare a queste lunghezze d’onda – fenomeno osservato già in altri pianeti del Sistema solare – gli autori ipotizzano una seconda sorgente: le aurore di Urano. Ipotesi tutta da verificare appena saranno disponibili nuovi dati

description: India and China are civilisational states with historical boundary disputes, whose roots lie in the colonial past. In modern times, both modern nation-states have taken a different politico-economic model in the global comity of nations. Both Asian powerhouses are separated by mighty Himalayan ranges geographically, but modern communication and transport technology have filled these geographical gaps. As a result, there is increasing Indian engagement in South-East Asia & East Asia; whereas Chinese engagement in South Asia and Indian Ocean region has brought them together to shape the Asian equilibrium in the multipolar world order. Over the years, both countries have transformed their relationship towards a cooperative framework in economic and military affairs for improving mutual trust and mutual understanding in their bilateral diplomatic relations. Furthermore, many developmental issues of common concern and global governance are acting as a catalyst to work towards their mutual benefit in regional and multilateral forums. Indeed, the India-China strategic partnership seems to be moving towards comprehensive partnership in the field of politics, economy, military, cultural and people to people contact. It is in these backdrops, one might wonder about the future trajectories of India-China bilateral relations in shaping the Asian equilibrium as well as the crucial role of their national interest in it.
Satelliti artificiali e space debris sporcano il cielo

Un recente studio teorico stima la luminosità di fondo cielo allo zenit dovuta alla diffusione della luce solare da parte di satelliti artificiali e space debris in orbita circumterrestre. Istintivamente si è portati a pensare che si tratti di una luminosità trascurabile, ma in realtà già ora il contributo alla brillanza di fondo cielo è circa il 10 per cento della luminosità naturale. Questo valore non farà che aumentare con l’entrata in servizio delle mega-costellazioni di satelliti

description: Cosmological simulations predict that early-type galaxies (ETGs) are the results of extended mass accretion histories. The latter are characterized by different numbers of mergers, mergers mass ratios and gas fractions, and timing. Depending on the sequence and nature of these mergers that follow the first phase of the in-situ star formation, these accretion histories may lead to ETGs that have low or high mass halos, and that rotate fast or slow. Since the stellar halos maintain the fossil records of the events that led to their formation, a discontinuity may be in place between the inner regions of ETGs and their outer halos, because the time required for the halos stars to exchange their energies and momenta is very long compared with the age of these systems. Exquisite deep photometry and extended spectroscopy for significant samples of ETGs are then used to quantify the occurrence and significance of such a transition in the galaxies structural and kinematical parameters. Once this transition radius is measured, its dependency with the effective radius of the galaxies light distribution and total stellar masses can be investigated. Such correlations can then be compared with the predictions of accreted, i.e. ex-situ vs. in-situ components from cosmological simulations to validate such models.

description: Using methods introduced by Scargle in 1978 we derive a cumulative version of the Lomb periodogram that exhibits frequency independent statistics when applied to cumulative noise. We show how this cumulative Lomb periodogram allows us to estimate the significance of log-periodic signatures in the S&P 500 anti-bubble that started in August 2000.

description: Developing of theoretical tools can be very helpful for supporting new pollutant detection. Nowadays, a combination of mass spectrometry and chromatographic techniques are the most basic environmental monitoring methods. In this paper, two organochlorine compound mass spectra classification systems were proposed. The classification models were developed within the framework of artificial neural networks (ANNs) and fast 1D and 2D molecular descriptor calculations. Based on the intensities of two characteristic MS peaks, namely, [M] and [M-35], two classification criterions were proposed. According to criterion I, class 1 comprises [M] signals with the intensity higher than 800 NIST units, while class 2 consists of signals with the intensity lower or equal than 800. According to criterion II, class 1 consists of [M-35] signals with the intensity higher than 100, while signals with the intensity lower or equal than 100 belong to class 2. As a result of ANNs learning stage, five models for both classification criterions were generated. The external model validation showed that all ANNs are characterized by high predicting power; however, criterion I-based ANNs are much more accurate and therefore are more suitable for analytical purposes. In order to obtain another confirmation, selected ANNs were tested against additional dataset comprising popular sunscreen agents disinfection by-products reported in previous works.

Survey Tool
User engagement

description: Coney is an innovative toolkit designed to enhance the user experience in surveys completion. Coney exploits a conversational approach: on the one hand, Coney allows modelling a conversational survey with an intuitive graphical editor; on the other hand, it allows publishing and administering surveys through a chat interface. Coney allows defining an arbitrary acyclic graph of interaction flows, in which the following question depends on the previous answer provided by the user. This offers a high degree of flexibility to survey designers that can simulate a human to human interaction, with a storytelling approach that enables different personalized paths. Coney’s interaction mechanism exploits the advantages of qualitative methods while performing quantitative research, by linking questions to the investigated variables and encoding answers. A preliminary evaluation of the approach shows that users prefer conversational surveys to traditional ones. Try Coney at bit.ly/try-coney!

description: The photonic environment can significantly influence emission properties and interactions among atomic systems. In such scenarios, frequently the electric dipole approximation is assumed that is justified as long as the spatial extent of the atomic system is negligible compared to the spatial variations of the field. While this holds true for many canonical systems, it ceases to be applicable for more contemporary nanophotonic structures. To go beyond the electric dipole approximation, we propose and develop in this article an analytical framework to describe the impact of the photonic environment on emission and interaction properties of atomic systems beyond the electric dipole approximation. Particularly, we retain explicitly magnetic dipolar and electric quadrupolar contributions to the light-matter interactions. We exploit a field quantization scheme based on electromagnetic Green's tensors, suited for dispersive materials. We obtain expressions for spontaneous emission rate, Lamb shift, multipole-multipole shift and superradiance rate, all being modified with dispersive environment. The considered influence could be substantial for suitably tailored nanostructured photonic environments, as demonstrated exemplarily.

description: We propose a simple model which describes the statistical properties of quantum jumps in a single-spin measurement using the oscillating cantilever-driven adiabatic reversals technique in magnetic resonance force microscopy. Our computer simulations based on this model predict the average time interval between two consecutive quantum jumps and the correlation time to be proportional to the characteristic time of the magnetic noise and inversely proportional to the square of the magnetic noise amplitude.

Sound from rotors in non-uniform flow

description: An analysis is presented for the evaluation of the acoustic field of a rotating source in a non-uniform potential flow. Other than the restriction to low flow Mach numbers, the method is exact and general. The variation in radiation properties with source position is handled by representation as a Fourier series in source angle, giving rise to an asymmetrically varying acoustic field evaluated by summation of the series. The method is used to develop an exact solution for the model problem of a rotor operating near a cylinder in cross-flow and sample calculations demonstrate the accuracy of the technique when compared to full numerical evaluation. The calculations show changes of greater than one decibel in the acoustic field due to flow non-uniformity at a flow Mach number of 0.15, a typical speed for propeller aircraft at take-off.

description: Josef Steindl’s impact on economic policy in Austria concentrated on three areas: Keynesian thinking, educational policy and technology policy. After returning to Vienna in 1950 Steindl advanced Keynesian and Kaleckian thinking in Austria and thus influenced a whole generation of economists. He pushed for an educational policy in Austria and emphasised the role of engineers, technicians and skilled workers in long-term economic growth. Closely related to this was his plea for a technology policy. As an industrial latecomer, Austria was able to import technologies for a long time; but once the country had caught up, it needed to stimulate innovation with a conscious technology policy.

description: \emph{Resonance Casimir-Polder interaction(RCPI)} occurs in nature when one or more atoms are in their excited states and the exchange of real photon is involved between them due to vacuum fluctuations of the quantum fields. In recent times, many attempts have been made to show that the curved spacetime such as the \emph{de-Sitter spacetime} can be separated from a \emph{thermal Minkowski spacetime} using \emph{RCPI}. Motivated from these ideas, here we study the \emph{RCPI} between two atoms that interact with a massive scalar field in Schwarzschild spacetime provided the atoms are placed in the near-horizon region. Subsequently, we use the tool of the \emph{open quantum system} and calculate the Lamb shift of the atomic energy level of the entangled states. We show that the behavior of \emph{RCPI} modifies depending on the mass of the scalar field. In the high mass limit, the interaction becomes short-range and eventually disappears beyond a characteristic length scale of $1/m$, where $m$ is the mass of the scalar field.

Type IIB Killing spinors and calibrations

description: In this paper we derive the full set of differential equations and some algebraic relations for p-forms constructed from type IIB Killing spinors. These equations are valid for the most general type IIB supersymmetric backgrounds which have a non-zero NS-NS 3-form field strength, H, and non-zero R-R field strengths, G^{(1)}, G^{(3)} and G^{(5)}. Our motivation is to use these equations to obtain generalised calibrations for branes in supersymmetric backgrounds. In particular, we consider giant gravitons in AdS_5 x S^5. These non-static branes have an interesting construction via holomorphic surfaces in C^{1,2} x C^3. We construct the p-forms corresponding to these branes and show that they satisfy the correct differential equations. Moreover, we interpret the equations as calibration conditions and derive the calibration bound. We find that giant gravitons minimise ``energy minus momentum''.
