Regularization of Newton Constant, Trans-Planckian Dispersion Relation, and Symmetry of Particle Spectrum

description: We consider the possibility that the UV completeness of a fundamental theory is achieved by a modification of propagators at large momenta. We assume that general covariance is preserved at all energies, and focus on the coupling of a scalar field to the background geometry as an example. Naively, one expects that the gravitational interaction, like Yukawa interactions, will be regularized by a propagator which decays to zero sufficiently fast above some cutoff scale, but we show that in order to avoid the ultra-violet divergence, the propagator should approach to a nonzero constant. This incompatibility between the regularizations of gravitational and Yukawa interactions suggests that a symmetry of the particle spectrum is needed for a UV complete fundamental theory.

description: Melitz and Ottaviano’s (2008) firm heterogeneity model predicts that trade liberalization induces a selection process from low to high productivity firms, that translates into an industry productivity growth. A similar firms’ selection effect is induced by market size. These predictions are tested across 25 European countries and 9 food industries, over the 1995–2008 period. Using different dynamic panel estimators we find a strong support for the model predictions, namely that import penetration is systematically positively related to productivity growth. The results are robust to measurement issues in productivity after controlling for market size, country and sector heterogeneities, and for the endogeneity of import competition. Interestingly, this positive relationship is almost exclusively driven by competition in final products coming from developed (especially EU-15) countries, suggesting that EU food imports constitute closer substitutes for domestic production than non-EU imports. These results have some potentially interesting policy implications.
Towards High Performance Low Complexity Calibration in Appearance Based Gaze Estimation

description: Appearance-based gaze estimation from RGB images provides relatively unconstrained gaze tracking. We have previously proposed a gaze decomposition method that decomposes the gaze angle into the sum of a subject-independent gaze estimate from the image and a subject-dependent bias. This paper extends that work with a more complete characterization of the interplay between the complexity of the calibration dataset and estimation accuracy. We analyze the effect of the number of gaze targets, the number of images used per gaze target and the number of head positions in calibration data using a new NISLGaze dataset, which is well suited for analyzing these effects as it includes more diversity in head positions and orientations for each subject than other datasets. A better understanding of these factors enables low complexity high performance calibration. Our results indicate that using only a single gaze target and single head position is sufficient to achieve high quality calibration, outperforming state-of-the-art methods by more than 6.3%. One of the surprising findings is that the same estimator yields the best performance both with and without calibration. To better understand the reasons, we provide a new theoretical analysis that specifies the conditions under which this can be expected.

description: We classify the pairs $(A,D)$ consisting of an $(ε,Γ)$-olor-commutative associative algebra $A$ with an identity element over an algebraically closed field $F$ of characteristic zero and a finite dimensional subspace $D$ of $(ε,Γ)$-color-commutative locally finite color-derivations of $A$ such that $A$ is $Γ$-graded $D$-simple and the eigenspaces for elements of $D$ are $Γ$-graded. Such pairs are the important ingredients in constructing some simple Lie color algebras which are in general not finitely-graded. As some applications, using such pairs, we construct new explicit simple Lie color algebras of generalized Witt type, Weyl type.

title: Preclinical and Clinical Early Alzheimer's Disease (AD) Biomarker Discovery Using Proteins and MicroRNAs Carried by Small Extracellular Vesicles (sEVs)
Creators: name: Moradi Bachiller, Soraya
Publisher: name: The Open University
Year: 2021

description: Alzheimer’s disease (AD) begins several years before the onset of symptoms. Unfortunately, current therapies treat too late and have limited efficacy. To improve this, clinical trials need to test a potential drug earlier in the disease progression by increasing the diagnostic accuracy of an early or even asymptomatic stage for which reliable and minimally invasive biomarkers are mandatory. In the context of blood-based biomarker discovery for early dementia, we focused on small extracellular vesicles (sEVs). SEVs contain specific cargoes that may reflect brain disease. They can cross the blood-brain barrier and can be isolated from biofluids, which may improve the detection of AD outside the brain. Therefore, we investigated NFL, TREM2, and a possible novel AD candidate called ECSIT in mouse and human plasma-sEVs. We found that TREM2, ECSIT and NFL are carried in mouse and human sEVs. Surprisingly, ECSIT showed lower levels in subjects with cognitive deficits, suggesting the possible role of this protein as sEVs-candidate biomarker for the early stage of AD, and prompting us to study its role in a cellular model for AD, where we found a possible link between ECSIT and APP. We also focused on a different approach to reveal the presence of dysregulated microRNAs in human plasma-sEVs across AD stages. To pursue this aim, we compared sEV-microRNA content from cognitively normal controls (Ctrl), mild cognitive impaired (MCI) and demented (AD) subjects. We showed a great number of dysregulated miRNAs in the AD stage. However, we were unable to detect them for the MCI stage. We conclude that our research contributed to assess the importance of plasma-sEVs as biomarker source and provided insights in the field of blood-based biomarker discovery for AD, that, we hope, may help to increase the diagnostic accuracy of the early stage of dementia, thus, enabling drug discovery progress.

description: We have re-estimated the surface density of the Galactic disk in the solar neighborhood within $\pm$ 0.4 kpc of the Sun using parallaxes and proper motions of a kinematically and spatially unbiased sample of 1476 old bright red giant stars from the Hipparcos catalog with measured radial velocities from Barbier-Brossat & Figon (2000). We determine the vertical distribution of the red giants as well as the vertical velocity dispersion of the sample, (14.4 $\pm$ 0.26 km/sec), and combine these to derive the surface density of gravitating matter in the Galactic disk as a function of the galactic coordinate $z$. The surface density of the disk increases from 10.5 $\pm$ 0.5 $M_{\odot}$ / pc$^2$ within $\pm$ 50 pc to 42 $\pm$ 6 $M_{\odot}$ / pc$^2$ within $\pm$ 350 pc. The estimated volume density of the galactic disk within $\pm$ 50 pc is about 0.1 $M_{\odot}$ / pc$^3$ which is close to the volume density estimates of the observed baryonic matter in the solar neighborhood.

description: This paper analyzes the extent to which the reduction of import tariffs – as a measure of import competition – affects the rate of quality upgrading in the agri-food sector. This relation is studied using highly disaggregated EU-15 import data from more than 70 countries in thousands of food products, in the period 1995-2007. We first infer product quality from trade data using the method recently proposed by Khandelwal (2010). In a second step, quality estimates are combined with information on trade policy to study the relationship between quality upgrading and competition within a ‘distance to the frontier’ model (Aghion et al. 2005). Consistent with the model predictions, we find strong support for the existence of an non-monotonic relationship between competition and quality upgrading, with varieties close to the world frontier more likely to upgrade quality in response to an increase in import competition. The results are robust to the use of different measures of import competition and alternative estimates of product quality.

description: Using \chiQM with configuration mixing, the contribution of the gluon polarization to the flavor singlet component of the total spin has been calculated phenomenologically through the relation ΔΣ(Q^2)=ΔΣ-\frac{3α_s(Q^2)}{2π}Δg(Q^2) as defined in the Adler-Bardeen scheme, where ΔΣon the right hand side is Q^2 independent. For evaluation the contribution of gluon polarization Δg'(=\frac{3α_s(Q^2)}{2π}Δg(Q^2)), ΔΣis found in the \chiQM by fixing the latest E866 data pertaining to \bar u-\bar d asymmetry and the spin polarization functions whereas ΔΣ(Q^2) is taken to be 0.30\pm0.06 and α_s= 0.287\pm0.020, both at Q^2=5{\rm GeV}^2. The contribution of gluon polarization Δg' comes out to be 0.33 which leads to an almost perfect fit for spin distribution functions in the \chiQM. When its implications for magnetic moments are investigated, we find perfect fit for many of the magnetic moments. If an attempt is made to explain the angular momentum sum rule for proton by using the above value of Δg', one finds the contribution of gluon angular momentum to be as important as that of the q \bar q pairs.

The Riemann-Hilbert problem for the equation is formulated on the basis of the corresponding $5\times5$ matrix spectral problem, which allows us to present a suitable representation for the solution of the equation. Then the Deift-Zhou steepest descent method is used to analyze the long time behavior of the coupled Sasa-Satsuma equation.

description: We propose a novel method that tracks fast moving objects, mainly non-uniform spherical, in full 6 degrees of freedom, estimating simultaneously their 3D motion trajectory, 3D pose and object appearance changes with a time step that is a fraction of the video frame exposure time. The sub-frame object localization and appearance estimation allows realistic temporal super-resolution and precise shape estimation. The method, called TbD-3D (Tracking by Deblatting in 3D) relies on a novel reconstruction algorithm which solves a piece-wise deblurring and matting problem. The 3D rotation is estimated by minimizing the reprojection error. As a second contribution, we present a new challenging dataset with fast moving objects that change their appearance and distance to the camera. High speed camera recordings with zero lag between frame exposures were used to generate videos with different frame rates annotated with ground-truth trajectory and pose.
Non-trivial time crystal-like ground state for gravitational perturbation in quadratic gravity

description: We consider gravitational perturbation around maximally symmetric background of a theory of gravity involving quadratic curvature correction. This leads to a decoupled model of the standard transverse, traceless graviton mode and an additional scalar degree of freedom. Evolution of the latter is governed by a Lagrangian, which depends on higher derivative terms, inherited from the quadratic curvature correction in the action. It turns out that stability of the gravitational theory allows the scalar sector to choose between possible lowest energy states (or, ground states), that can sustain periodic form of inhomogeneity, either in space or in time. The latter, with a restricted form of invariance in time translation, is possibly a variant form of the time crystal. Existence of this novel ground state, depicting a time crystal, is solely related to the presence of higher curvature terms in the action. In particular, this non-trivial condensate-like ground state describe the spacetime fabric itself by introducing fundamental scales in the theory. Possible implications are also discussed.

Multi-level 3D non-LTE computations of lithium lines in the metal-poor halo stars HD140283 and HD84937

description: The lithium abundances in metal-poor halo stars are of importance for cosmology, galaxy evolution and stellar structure. In an attempt to study possible systematic errors in the derived Li abundances, the line formation of LiI lines has been investigated by means of realistic 3D hydrodynamical model atmospheres of halo stars and 3D non-LTE radiative transfer calculations. These are the first detailed 3D non-LTE computations reported employing a multi-level atomic model showing that such problems are now computationally tractable. The detailed computations reveal that the LiI population has a strong influence from the radiation field rather than the local gas temperature, indicating that the low derived Li abundances found by Asplund et al. (1999) are an artifact of their assumption of LTE. Relative to 3D LTE, the detailed calculations show pronounced over-ionization. In terms of abundances the 3D non-LTE values are within 0.05 dex of the 1D non-LTE results for the particular cases of HD140283 and HD84937, which is a consequence of the dominance of the radiation in determining the population density of LiI. Although 3D non-LTE can be expected to give results rather close (+/-0.1 dex) to 1D non-LTE for this reason, there may be systematic trends with metallicity and effective temperature.

description: The study focuses on the 3D electro-hydrodynamic (EHD) instability for flow between to parallel electrodes with unipolar charge injection with and without cross-flow. Lattice Boltzmann Method (LBM) with two-relaxation time (TRT) model is used to study flow pattern. In the absence of cross-flow, the base-state solution is hydrostatic, and the electric field is one-dimensional. With strong charge injection and high electrical Rayleigh number, the system exhibits electro-convective vortices. Disturbed by different perturbation patterns, such as rolling pattern, square pattern, and hexagon pattern, the flow patterns develop according to the most unstable modes. The growth rate and the unstable modes are examined using dynamic mode decomposition (DMD) of the transient numerical solutions. The interactions between the applied Couette and Poiseuille cross-flows and electroconvective vortices lead to the flow patterns change. When the cross-flow velocity is greater than a threshold value, the spanwise structures are suppressed; however, the cross-flow does not affect the streamwise patterns. The dynamics of the transition is analyzed by DMD. Hysteresis in the 3D to 2D transition is characterized by the non-dimensional parameter Y, a ratio of the coulombic force to viscous term in the momentum equation. The change from 3D to 2D structures enhances the convection marked by a significant increase in the electric Nusselt number.

description: U.S. annual per capita use of onions increased 50 percent during the last 20 years. To meet the domestic demand and population growth, as well as export demand, U.S. producers doubled production. Western States increased their share of total production. Grower and retail onion prices fluctuated widely due to changes in shortrun supply; however, during the last 15 years grower prices have remained relatively high. The quantity of U.S. onion imports has increased faster than exports during the last 20 years, but the balance of trade in value tenns was about equal during the early 1990's. This bulletin provides detailed statistics on onions for the United States and the world for 1960-93. Statistics on U.S. area, yield, production, and value are presented by State. World onion area, production, and trade are presented by country. Other statistics refer to domestic shipments, arrivals in selected U.S. cities, wholesale and retail prices, price spreads, and chemical fertilizer and pesticide applications.

description: Quantum computers can efficiently simulate the dynamics of quantum systems. In this paper, we study the cost of digitally simulating the dynamics of several physically relevant systems using the first-order product formula algorithm. We show that the errors from different Trotterization steps in the algorithm can interfere destructively, yielding a much smaller error than previously estimated. In particular, we prove that the total error in simulating a nearest-neighbor interacting system of $n$ sites for time $t$ using the first-order product formula with $r$ time slices is $O({nt}/{r}+{nt^3}/{r^2})$ when $nt^2/r$ is less than a small constant. Given an error tolerance $ε$, the error bound yields an estimate of $\max\{O({n^2t}/ε),O({n^2 t^{3/2}}/{ε^{1/2}})\}$ for the total gate count of the simulation. The estimate is tighter than previous bounds and matches the empirical performance observed in Childs et al. [PNAS 115, 9456-9461 (2018)]. We also provide numerical evidence for potential improvements and conjecture an even tighter estimate for the gate count.

Profitability of FCS institutions generally improved over the period as the agricultural economy strengthened and a favorable interest rate environment persisted. Improved profitability enabled FCS institutions to strengthen their capital positions. Rural residence loans did not approach their statutory limit of 15 percent of total loans in any district, but constituted more than 5 percent of total loans in three districts.

description: Motivated by the recent claim for gravitational lensing by a cosmic string, we reinvestigate the probability of finding such an event with upcoming wide-field surveys. If an observed lensing event is suspected to be due to a string, observations of the vicinity of the event in a circle of diameter L centered on the observed lens should reveal several additional lensing events. For a string located nearby (z\lesssim 0.5), we find that observations in a region of size \approx 1 arcmin^2 will see \sim 100 objects, of which \sim 5 would be lensed by the string, compared to \sim 0.1 lensed by conventional sources.

description: We explore the scattering of Dirac electrons in a double-gated topological insulator in the presence of magnetic proximity effects and warped surface states. It is found that a magnetic field can shift the Dirac cone in momentum space and deform the constant-energy contour, or opens up a band gap at the Dirac point, depending on the magnetization orientation. The double gate voltage induces quantum wells and/or quantum barriers on the surface of topological insulators, generating surface resonant tunnelling states. It is found that the hexagonal warping effect can increase the electronic transport at high energies when the constant-energy contour exhibits a snowflake shape. The energy-dependent conductances in the parallel and antiparallel magnetic configurations exhibit out-of-phase oscillations due to the quantum interference of propagating waves in the region between the two magnetized segments. Although the conductance spectrum of the double-well structure is higher than that of the double-barrier structure, the magnetoresistance ratio versus the separation distance between the two magnetized barriers exhibits pronounced oscillations due to the resonant tunnelling states. We show that the surface state transport can be controlled by the exchange field and gate voltage without breaking time reversal symmetry, suggesting that the double gated and magnetized topological insulators can be utilized to achieve a large magnetoresistance ratio with a tunable sign.

description: We have converted an ultracold Fermi gas of $^6$Li atoms into an ultracold gas of $^6$Li$_2$ molecules by adiabatic passage through a Feshbach resonance. Approximately $1.5 \times 10^5$ molecules in the least-bound, $v = 38$, vibrational level of the X$^1 Σ^+_g$ singlet state are produced with an efficiency of 50%. The molecules remain confined in an optical trap for times of up to 1 s before we dissociate them by a reverse adiabatic sweep.

description: Pressure studies of CeRh_1-xIr_xIn_5 indicate two superconducting phases as a function of x, one with T_c >= 2 K for x < 0.9 and the other with T_c < 1.2 K for x > 0.9. The higher T_c phase, phase-1, emerges in proximity to an antiferromagnetic quantum-critical point; whereas, Cooper pairing in the lower T_c phase-2 is inferred to arise from fluctuations of a yet to be found magnetic state. The T-x-P phase diagram of CeRh_1-xIr_xIn_5, though qualitatively similar, is distinctly different from that of CeCu_2(Si_1-xGe_x)_2.

description: We propose an approach to search for axion dark matter with a specially designed superconducting radio frequency cavity, targeting axions with masses $m_a \lesssim 10^{-6} \text{ eV}$. Our approach exploits axion-induced transitions between nearly degenerate resonant modes of frequency $\sim$ GHz. A scan over axion mass is achieved by varying the frequency splitting between the two modes. Compared to traditional approaches, this allows for parametrically enhanced signal power for axions lighter than a GHz. The projected sensitivity covers unexplored parameter space for QCD axion dark matter for $10^{-8} \text{ eV} \lesssim m_a \lesssim10^{-6} \text{ eV}$ and axion-like particle dark matter as light as $m_a \sim 10^{-14} \text{ eV}$.

description: BIMA observations of the Orion nebula discovered a giant flare from a young star previously undetected at millimeter wavelengths. The star briefly became the brightest compact object in the nebula at 86 GHz. Its flux density increased by more than a factor of 5 on a timescale of hours, to a peak of 160 mJy. This is one of the most luminous stellar radio flares ever observed. Remarkably, the Chandra X-ray observatory was in the midst of a deep integration of the Orion nebula at the time of the BIMA discovery; the source's X-ray flux increased by a factor of 10 approximately 2 days before the radio detection. Follow-up radio observations with the VLA and BIMA showed that the source decayed on a timescale of days, then flared again several times over the next 70 days, although never as brightly as during the discovery. Circular polarization was detected at 15, 22, and 43 GHz, indicating that the emission mechanism was cyclotron. VLBA observations 9 days after the initial flare yield a brightness temperature Tb > 5 x 10^7 K at 15 GHz. Infrared spectroscopy indicates the source is a K5V star with faint Br gamma emission, suggesting that it is a weak-line T Tauri object. Zeeman splitting measurements in the infrared spectrum find B ~ 2.6 +/- 1.0 kG. The flare is an extreme example of magnetic activity associated with a young stellar object. These data suggest that short observations obtained with ALMA will uncover hundreds of flaring young stellar objects in the Orion region.

The sfermion mass spectrum of the MSSM at the one-loop level

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The sfermion-mass spectrum of the minimal supersymmetric standard model is investigated at the one-loop level. An on-shell scheme has been specified for renormalization of the basic breaking parameters of the sfermionic sector. Owing to SU(2)-invariance, the soft-breaking mass parameters of the left-chiral scalar fermions of each isospin doublet are identical. Thus, one of the sfermion-masses of each doublet can be expressed in terms of the other masses and receives a mass shift at the one-loop level with respect to the lowest-order value, which can be of $O(10$ GeV). Both strong and electroweak contributions have been calculated for scalar quarks and leptons.

Diritto e giustizia nella Grande Romania. Eredità imperiali, nazionalismo, state-building (1919-1927)
Creators: name: Magno, Francesco
Publisher: name: Università degli studi di Trento
Year: 2021

description: Nel 1918, a seguito della vittoria nella prima guerra mondiale, la Romania inglobò all’interno dei suoi confini regioni abitate in prevalenza da popolazioni romenofone, ma precedentemente parte di grandi imperi multinazionali. Ad ovest acquisì la Transilvania, a nord la Bucovina, ex territori asburgici, e a nord-est la Bessarabia, dal 1812 appartenente all’impero russo. Nacque così la Grande Romania, uno Stato che si estendeva dall’Europa centrale fino al Mar Nero. Le regioni annesse, che contenevano al loro interno cospicue minoranze etnico-linguistiche, andavano integrate giuridicamente e istituzionalmente all’interno del Regno romeno, uniformando leggi e procedure eterogenee. La ricerca si è concentrata sul processo di unificazione giuridica e legislativa che ebbe luogo nella Grande Romania tra il 1918 e il 1927, mettendo in luce gli episodi di resistenza, da parte di esponenti delle professioni legali, ai progetti di nazionalizzazione portati avanti dal potere politico. Molti romeni formatisi nei contesti imperiali russo e austro-ungarico sperarono infatti di poter portare in Romania gli elementi positivi dei loro sistemi giuridici e legislativi, ma si scontrarono spesso con la reticenza di Bucarest. La tesi principale del presente studio è che per i professionisti della giustizia, nel periodo di transizione dagli imperi alla Grande Romania, la volontà di tutelare diritti acquisiti e posizione sociale da una parte, e il desiderio di difendere un ordine simbolico che trovava espressione nel diritto dall’altra, furono più importanti del nazionalismo nell’indirizzare la loro azione sociale e politica.
