description: We combine samples of spiral galaxies and starburst systems observed with ISOCAM to investigate the reliability of mid-infrared (MIR) dust emission as a quantitative tracer of star formation (SF) activity. The total sample covers very diverse galactic environments and probes a much wider dynamic range in SF rate density than previous similar studies. We find that both the monochromatic 15 micron continuum and the 5-8.5 micron emission constitute excellent indicators of the SF rate as quantified by the Lyman continuum luminosity L_Lyc, within specified validity limits which are different for the two tracers. Normalized to projected surface area, the 15 micron luminosity S_15ct is directly proportional to S_Lyc over several orders of magnitude. Two regimes are distinguished from the relative offsets in the observed relation: the proportionality factor increases by a factor of ~ 5 between quiescent disks in spiral galaxies, and moderate to extreme star-forming environments in circumnuclear regions of spirals and in starburst systems. The transition occurs near S_Lyc ~ 10^2 L_sun pc^{-2} and is interpreted as due to very small dust grains starting to dominate the emission at 15 microns over aromatic species above this threshold. The 5-8.5 micron luminosity per unit area is also proportional to S_Lyc, with a single conversion factor from the most quiescent objects in the sample up to S_Lyc ~ 10^4 L_sun pc^{-2}, where the relation then flattens. The turnover is attributed to depletion of aromatic band carriers in the harsher conditions prevailing in extreme starbursts. The observed relations provide empirical calibrations useful for estimating SF rates from mid-IR observations in deeply embedded HII regions and obscured starbursts, and for predictions from evolutionary synthesis models.

Generalized mode-coupling theory of the glass transition. I. Numerical results for Percus-Yevick hard spheres

description: Mode-coupling theory (MCT) constitutes one of the few first-principles-based approaches to describe the physics of the glass transition, but the theory's inherent approximations compromise its accuracy in the activated glassy regime. Here we show that microscopic generalized mode-coupling theory (GMCT), a recently proposed hierarchical framework to systematically improve upon standard MCT, provides a promising pathway toward a more accurate first-principles description of glassy dynamics. We present a comprehensive numerical analysis for Percus-Yevick hard spheres by performing explicitly wavenumber- and time-dependent GMCT calculations up to sixth order. Specifically, we calculate the location of the critical point, the associated non-ergodicity parameters, the time-dependent dynamics of the density correlators at both absolute and reduced packing fractions, and we test several universal scaling relations in the $α$- and $β$-relaxation regimes. It is found that higher-order GMCT can successfully remedy some of standard MCT's pathologies, including an underestimation of the critical glass transition density and an overestimation of the hard-sphere fragility. Furthermore, we numerically demonstrate that the celebrated scaling laws of standard MCT are preserved in GMCT at all closure levels, and that the predicted critical exponents manifestly improve as more levels are incorporated in the GMCT hierarchy. Although formally the GMCT equations should be solved up to infinite order to reach full convergence, our finite-order GMCT calculations unambiguously reveal a uniform convergence pattern for the dynamics. We thus argue that GMCT can provide a feasible and controlled means to bypass MCT's main uncontrolled approximation, offering hope for the future development of a quantitative first-principles theory of the glass transition.

description: The gravity effects in high-energy scattering, described by a four-dimensional eikonal amplitude related to gravireggeons induced by compact extra dimensions are studied. It is demonstrated that the real part of the eikonal (with a massless mode subtracted) dominates its imaginary part at both small and large impact parameters, in contrast to the usual case of hadronic high-energy behavior. The real part of the scattering amplitude exhibits an exponential falloff at large momentum transfer, similar to that of the imaginary part of the amplitude.

description: We analyze the vacuum stability in the inert Higgs doublet extension of the Standard Model (SM), augmented by right-handed neutrinos (RHNs) to explain neutrino masses at tree level by the seesaw mechanism. We make a comparative study of the high- and low-scale seesaw scenarios and the effect of the Dirac neutrino Yukawa couplings on the stability of the Higgs potential. Bounds on the scalar quartic couplings and Dirac Yukawa couplings are obtained from vacuum stability and perturbativity considerations. The regions corresponding to stability, metastability and instability of the electroweak vacuum are identified. These theoretical constraints give a very predictive parameter space for the couplings and masses of the new scalars and RHNs which can be tested at the LHC and future colliders. The lightest non-SM neutral CP-even/odd scalar can be a good dark matter candidate and the corresponding collider signatures are also predicted for the model.

description: The density driven Mott transition is studied by means of Dynamical Mean-Field Theory in the Hubbard-Holstein model, where the Hubbard term leading to the Mott transition is supplemented by an electron-phonon (e-ph) term. We show that an intermediate e-ph coupling leads to a first-order transition at T=0, which is accompanied by phase separation between a metal and an insulator. The compressibility in the metallic phase is substantially enhanced. At quite larger values of the coupling a polaronic phase emerges coexisting with a non-polaronic metal.

Interwell meter-scale depositional heterogeneity is a key geologic factor behind un-even fluid advance in carbonate reservoirs undergoing waterflooding and enhanced oil recovery developments. Subsurface data (seismic and well data) are limited in both resolution and data density to resolve this level of heterogeneity. Outcrop analogues are commonly utilized to fill this data gap on interwell heterogeneity. However, most outcrop analogue studies are limited to vertical sections and two-dimensional interpolated profiles. This study builds from outcrops high-fidelity 3D depositional models using 3D drone photogrammetry, cores and 3D geophysical data. We applied our methodology to the top 40 m of the Late-Jurassic Hanifa Formation outcrop in Wadi Birk, Saudi Arabia. Datasets include a multi-resolution 16 km2 drone photogrammetry survey over criss-crossing wadi systems, measured vertical sections from 10 different locations including spectral gamma-ray, 160 hand samples and thin sections, three 50 m-long cores taken from behind the outcrops, a 19 km-long network of 2D and 3D Ground Penetrating Radar, and 1.9 km of 2D seismic. The overall cleaning upward succession contains shallow marine wackestones/packstones at the bottom, followed by stromatoporoid/coral complex (with m-scale lateral and vertical heterogeneity) that is capped by oncolithic and cross-bedded peloidal grainstones at the top. The stromatoporoid/coral buildups display biostromal/biohermal morphology with inter-buildup space filled by wackestones/floatstones/grainstones. The smaller stromatoporoid/coral complexes ( 10 m) are more circular, while the larger are pseudo-ellipsoid (30-50 m long, 5-10 m wide), indicating preferential alignment with local/regional currents.

description: In this article we propose a new geometrization of the radiative phase space of asymptotically flat space-times: we show that the geometry induced on null-infinity by the presence of gravitational waves can be understood to be a generalisation of the tractor calculus of conformal manifolds adapted to the case of degenerate conformal metrics. It follows that the whole formalism is, by construction, manifestly conformally invariant. We first show that a choice of asymptotic shear amounts to a choice of linear differential operator of order two on the bundle of scales of null-infinity. We refer to these operators as Poincaré operators. We then show that Poincaré operators are in one-to-one correspondence with a particular class of tractor connections which we call "null-normal" (they generalise the normal tractor connection of conformal geometry). The tractor curvature encodes the presence of gravitational waves and the non-uniqueness of flat null-normal tractor connections correspond to the "degeneracy of gravity vacua" that has been extensively discussed in the literature. This work thus brings back the investigation of the radiative phase space of gravity to the study of (Cartan) connections and associated bundles. This should allow, in particular, to proliferate invariants of the phase space.

A Free-Electron Laser in the Pulsar Magnetosphere

Year: 2004

description: We have studied systematically the free-electron laser in the context of high brightness pulsar radio emission. In this paper, we have numerically examined the case where a transverse electromagnetic wave is distorting the motion of a relativistic electron beam while travelling over one stellar radius ($ approx 10 :{km}$). For different sets of parameters, coherent emission is generated by bunches of beam electrons in the radio domain, with bandwidths of 3 GHz. Pulse power often reached $10^{13} :{W}$, which corresponds with brightness temperature of $10^{30} :{K}$. The duration of these pulses is of the order of nanoseconds. In the context of pulsar radio emission, our results indicate that the laser can produce elementary bursts of radiation which build up the observed microstructures of a few tens of microseconds duration. The process is sensitive mostly to the beam particles energy, number density and the background magnetic field, but much less so to the transverse wave parameters. We demonstrate that the operation of a free-electron laser with a transverse electromagnetic wiggler in the pulsar magnetosphere occurs preferably at moder ate Lorentz factors $ gamma geq 100$, high beam density $n gtrsim 0.1 n_{textrm{GJ}}(r_ ast)$ where $n_{textrm{GJ}}(r_ ast)$ is the Goldrei ch-Julian density at a stellar radius $r_ ast$, and finally, at large altitude where the background magnetic field is low $B_0 leq 10^{-2} textrm{T}$.

Loess-palaeosol sequences (LPSs) are valuable records of Quaternary environmental change especially in the northern hemisphere. In Eurasian LPS, the alternation of loess and palaeosol intervals reflects the uninterrupted but fluctuating dust deposition during the Quaternary and the fluctuations of temperature and precipitation responsible for the formation of palaeosol horizons. At Zemun (Middle Danube Basin, Serbia), a studied LPS covers four interglacial-glacial cycles. We use standard colorimetric data, containing luminance (L*), redness (a*) and blueness (b*), backscattered wavelength intensities of the visible light spectrum (400-700 nm), and first derivatives of the measured spectra indicative for assessing relative hematite and goethite contents. Environmental magnetic data comprise indicators for intensity of pedogenesis (frequency dependence of the magnetic susceptibility) and for magnetic mineralogy (high- and low-field susceptibilities) of 490 samples. Age models of LPSs are often created by the direct correlation of low-frequency susceptibility records with global paleoclimate stacks (in particular the LR04 stack, Lisiecki Raymo, 2005) and global ice models (Imbrie Imbrie 1980), especially when absolute dating techniques are limited. Here we apply several spectral analysis techniques for investigating orbital forcing at the Zemun site. The resulting age model goes back to ~430 ka, and shows distinct differences between proxy records. These differences are presumably caused by different sensitivities of the employed palaeoenvironmental proxy parameters reflecting their non-linear response to changing climate conditions.

description: We consider the possibility that a right-handed sneutrino can serve as the source of energy density perturbations leading to structure formation in cosmology. The cosmological evolution of a coherently oscillating condensate of right-handed sneutrinos is studied for the case where reheating after inflation is due to perturbative inflaton decays. For the case of Dirac neutrinos, it is shown that some suppression of Planck scale-suppressed corrections to the right-handed neutrino superpotential is necessary. cH^2 corrections to the sneutrino mass squared term must also be suppressed during inflation (|c| < 0.1), in which case, depending on the magnitude of |c| during inflation, a significantly blue (if c > 0) or red (if c < 0) perturbation spectrum is possible. R-parity must also be broken in order to ensure that the Universe is not overclosed by LSPs from the late decay (at temperatures 1-10 MeV) of the right-handed sneutrino condensate. The resulting expansion rate during inflation can be significantly smaller than in conventional supersymmetric inflation models (as low as 10^6 GeV is possible). For the case of Majorana neutrinos, a more severe suppression of Planck-suppressed superpotential corrections is required. In addition, the Majorana sneutrino condensate is likely to be thermalised before it can dominate the energy density, which would exclude the Majorana right-handed sneutrino as a curvaton.

description: The Berezinskii-Kosterlitz-Thouless (BKT) transition is expected to have a clear signature on the specific heat. The singularity at the transition temperature $T_{BKT}$ is predicted to be immeasurable, and a broad non-universal peak is expected at $T>T_{BKT}$. Up to date this has not been observed in two-dimensional superconductors. We use a unique highly sensitive technique to measure the specific heat of ultrathin Pb films. We find that thick films exhibit a specific heat jump at $T_C$ that is consistent with BCS theory. As the film thickness is reduced below the superconducting coherence length and the systems enters the 2D limit the specific heat reveals BKT-like behavior. We discuss these observations in the framework of the continuous BCS-BKT crossover as a function of film thickness.

We illustrate our method by applying it to the spin dynamics of a non-equilibrium quantum dot, computing the voltage-dependent spin relaxation rate and showing that, at weak coupling, the fluctuation-dissipation relation for the spin of a quantum dot is voltage-dependent. We confirm the voltage-dependent Curie susceptibility recently found by Parcollet and Hooley [Phys. Rev. B {\bf 66}, 085315 (2002)].

description: In a Fog-Radio Access Network (F-RAN), edge caching and fronthaul connectivity to a cloud processor are utilized for the purpose of content delivery. Additional Device-to-Device (D2D) communication capabilities can support the operation of an F-RAN by alleviating fronthaul and cloud processing load, and reducing the delivery time. In this work, basic limits on the normalized delivery time (NDT) metric, which captures the high signal-to-noise ratio worst-case latency for delivering any requested content to the users, are derived. Assuming proactive offline caching, out-of-band D2D communication, and an F-RAN with two edge nodes and two users, an information-theoretically optimal caching and delivery strategy is presented. Unlike prior work, the NDT performance is studied under pipelined transmission, whereby the edge nodes transmit on the wireless channel while simultaneously receiving messages over the fronthaul links, and the users transmit messages over the D2D links while at the same time receiving on the wireless channel. Insights are provided on the regimes in which D2D communication is beneficial, and the maximum improvement to the latency is characterized.

The brown bear (Ursus arctos) is one of the closest living relatives to the extinct Late Pleistocene cave bear (Ursus spelaeus). According to a preliminary analysis late Pleistocene bear skull fragments found in caves in Belgium show intermediate phenotypes between U. arctos and U. spelaeus. To analyse a potential hybridisation between these two species a 3D geometric morphometric analysis was performed. In total eight skull fragments were analysed: three cranial fragments and five mandible fragments. The fragments were digitized using a CT scan and then a 3D model was created using segmentation. Landmarks were chosen corresponding to existing studies on U. spelaeus and an existing dataset was used to compare the potential hybrids to existing landmark data of U. spelaeus and U. arctos. The existing dataset was combined with the potential hybrid data and a generalized Procrustes superimposition was used to project the landmarks onto tangent space by orthogonal projection. A linear regression was performed on the Procrustes coordinates onto log centroid size to remove the effect of allometry. A principal components analysis was then performed using the regression residuals. Depending on the landmarks chosen and the principal components displayed, some specimen showed to be in an intermediate space between the two reference groups. Some specimen were plotted as belonging to U. arctos although they possess the dental formula of U. spelaeus. These results could point to a potential hybridisation between U. arctos and U. spelaeus in the Late Pleistocene.

description: The interference of two independent single-photon pulses impinging on a beam splitter is analysed in a generalised time-resolved manner. Different aspects of the phenomenon are elaborated using different representations of the single-photon wave packets, like the decomposition into single-frequency field modes or spatio-temporal modes matching the photonic wave packets. Both representations lead to equivalent results, and a photon-by-photon analysis reveals that the quantum-mechanical two-photon interference can be interpreted as a classical one-photon interference once a first photon is detected. A novel time-dependent quantum-beat effect is predicted if the interfering photons have different frequencies. The calculation also reveals that full two-photon fringe visibility can be achieved under almost any circumstances by applying a temporal filter to the signal.

description: We show how to search N items arranged on a $\sqrt{N}\times\sqrt{N}$ grid in time $O(\sqrt N \log N)$, using a discrete time quantum walk. This result for the first time exhibits a significant difference between discrete time and continuous time walks without coin degrees of freedom, since it has been shown recently that such a continuous time walk needs time $Ω(N)$ to perform the same task. Our result furthermore improves on a previous bound for quantum local search by Aaronson and Ambainis. We generalize our result to 3 and more dimensions where the walk yields the optimal performance of $O(\sqrt{N})$ and give several extensions of quantum walk search algorithms for general graphs. The coin-flip operation needs to be chosen judiciously: we show that another ``natural'' choice of coin gives a walk that takes $Ω(N)$ steps. We also show that in 2 dimensions it is sufficient to have a two-dimensional coin-space to achieve the time $O(\sqrt{N} \log N)$.

description: Risk management and income stabilization have been gaining increasing attention in the EU’s agricultural policy debate, also in connection to the recent proposal of a specific package of measures hypothesized in the ongoing CAP reform. The paper summarizes the current policy picture at EU and Italian levels, deepening country specific issues of construction of an income stabilization tool and providing a quantitative appreciation of the financial importance of a generalized measure of income stabilization for Italian farms. Estimates of farms’ losses and compensations are differentiated by type of farming and dimension of farms. The results are discussed looking at the perspectives of the new policies under scrutiny
Zeros of repeated derivatives of random polynomials

description: It has been shown that zeros of Kac polynomials $K_n(z)$ of degree $n$ cluster asymptotically near the unit circle as $n\to\infty$ under some assumptions. This property remains unchanged for the $l$-th derivative of the Kac polynomials $K^{(l)}_n(z)$ for any fixed order $l$. So it's natural to study the situation when the number of the derivatives we take depends on $n$, i.e., $l=N_n$. We will show that the limiting global behavior of zeros of $K_n^{(N_n)}(z)$ depends on the limit of the ratio $N_n/n$. In particular, we prove that when the limit of the ratio is strictly positive, the property of the uniform clustering around the unit circle fails; when the ratio is close to 1, the zeros have some rescaling phenomenon. Then we study such problem for random polynomials with more general coefficients. But things, especially the rescaling phenomenon, become very complicated for the general case when $N_n/n\to 1$, where we compute the case of the random elliptic polynomials to illustrate this.

description: A blazed chirped Bragg grating in a planar silica waveguide device was used to create an integrated diffractive element for a spectrometer. The grating diffracts light from a waveguide and creates a wavelength dependent focus in a manner similar to a bulk diffraction grating spectrometer. An external imaging system is used to analyse the light, later device iterations plan to integrate detectors to make a fully integrated spectrometer. Devices were fabricated with grating period chirp rates in excess of 100nm/mm, achieving a focal length of 5.5mm. Correction of coma aberrations resulted in a device with a footprint of 20mm x 10mm, a peak FWHM resolution of 1.8nm, a typical FWHM resolution of 2.6nm and operating with a 160nm bandwidth centered at 1550nm.

Electronic structure of nuclear-spin-polarization-induced quantum dots

description: We study a system in which electrons in a two-dimensional electron gas are confined by a nonhomogeneous nuclear spin polarization. The system consists of a heterostructure that has non-zero nuclei spins. We show that in this system electrons can be confined into a dot region through a local nuclear spin polarization. The nuclear-spin-polarization-induced quantum dot has interesting properties indicating that electron energy levels are time-dependent because of the nuclear spin relaxation and diffusion processes. Electron confining potential is a solution of diffusion equation with relaxation. Experimental investigations of the time-dependence of electron energy levels will result in more information about nuclear spin interactions in solids.

description: Security is of primary importance to vehicles. The viability of performing remote intrusions onto the in-vehicle network has been manifested. In regard to unmanned autonomous cars, limited work has been done to detect intrusions for them while existing intrusion detection systems (IDSs) embrace limitations against strong adversaries. In this paper, we consider the very nature of autonomous car and leverage the road context to build a novel IDS, named Road context-aware IDS (RAIDS). When a computer-controlled car is driving through continuous roads, road contexts and genuine frames transmitted on the car's in-vehicle network should resemble a regular and intelligible pattern. RAIDS hence employs a lightweight machine learning model to extract road contexts from sensory information (e.g., camera images and distance sensor values) that are used to generate control signals for maneuvering the car. With such ongoing road context, RAIDS validates corresponding frames observed on the in-vehicle network. Anomalous frames that substantially deviate from road context will be discerned as intrusions. We have implemented a prototype of RAIDS with neural networks, and conducted experiments on a Raspberry Pi with extensive datasets and meaningful intrusion cases. Evaluations show that RAIDS significantly outperforms state-of-the-art IDS without using road context by up to 99.9% accuracy and short response time.

description: We describe a ten dimensional supergravity geometry which is dual to a gauge theory that is non-supersymmetric Yang Mills in the infra-red but reverts to $N$=4 super Yang Mills in the ultra-violet. A brane probe of the geometry shows that the scalar potential of the gauge theory is stable. We discuss the infra-red behaviour of the solution. The geometry describes a Schroedinger equation potential that determines the glueball spectrum of the theory; there is a mass gap and a discrete spectrum. The glueball mass predictions match previous AdS/CFT Correspondence computations in the non-supersymmetric Yang Mills theory, and lattice data, at the 10% level.

Transfer Learning Between Related Tasks Using Expected Label Proportions

description: Deep learning systems thrive on abundance of labeled training data but such data is not always available, calling for alternative methods of supervision. One such method is expectation regularization (XR) (Mann and McCallum, 2007), where models are trained based on expected label proportions. We propose a novel application of the XR framework for transfer learning between related tasks, where knowing the labels of task A provides an estimation of the label proportion of task B. We then use a model trained for A to label a large corpus, and use this corpus with an XR loss to train a model for task B. To make the XR framework applicable to large-scale deep-learning setups, we propose a stochastic batched approximation procedure. We demonstrate the approach on the task of Aspect-based Sentiment classification, where we effectively use a sentence-level sentiment predictor to train accurate aspect-based predictor. The method improves upon fully supervised neural system trained on aspect-level data, and is also cumulative with LM-based pretraining, as we demonstrate by improving a BERT-based Aspect-based Sentiment model.
