description: A project envisaged by the Albanian Institute for International Studies (AIIS), in cooperation with scholars and policy experts from the region, funded by Hanns Seidel Foundation Albania.
 The most common and relevant questions and quandaries that are raised by the Open Balkans initiative as indicated in the individual country reports on the Open Balkans relate to the added value of this intra-regional initiative of regional cooperation among the paraphernalia of similar ones, and whether the Open Balkans can foster peacebuilding in the region as well as complement the integration of the region into the European Union. To understand the functioning, the opportunities, and the ways through which the faltering of and skepticism on the Open Balkans initiative can be rectified, the report will address the effect of the EU leverage in the Western Balkans in contrast with other external actors, as well as highlight the political and economic conditions of the polities in the region, which underpin the Open Balkans initiative's impact. Probably the project of the Open Balkans would have been inconceivable if the process of the EU enlargement of the Western Balkans had not been complex, to some extent incoherent in sustaining the commitments for the accession of the Western Balkans, and less indicative of various competing strategies and mechanisms instead of full membership. On the other hand, the ushering of the international order into an age of hybridity had increased the leverage of non-Western external actors. A restricted power elite dependent on informal networks and patronage, if not state capture, characterizes the presence of competitive authoritarian regimes in the Western Balkans and weakens the effectiveness of the Open Balkans initiative.

description: This paper deals with function field analogues of the famous theorem of Landau which gives the asymptotic density of sums of two squares in $\mathbb{Z}$. We define the analogue of a sum of two squares in $\mathbb{F}_q[T]$ and estimate the number $B_q(n)$ of such polynomials of degree $n$ in two cases. The first case is when $q$ is large and $n$ fixed and the second case is when $n$ is large and $q$ is fixed. Although the methods used and main terms computed in each of the two cases differ, the two iterated limits of (a normalization of) $B_q(n)$ turn out to be exactly the same.

description: The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment which is under construction. The primary goal of JUNO is to determine the neutrino mass ordering and precisely measure the oscillation parameters by reactor anti-neutrinos. There will be about 20000 20-inch PMTs equipped for JUNO, which include 15000 MCP-PMTs and 5000 dynode-PMTs. To achieve the designed 3% energy resolution, the PMTs are required to have high photon detection efficiency, high optical coverage, and low failure rate during JUNO running. Instrumentation of these PMTs for JUNO includes PMT testing, high-voltage divider production, waterproof potting, chain implosion protection, and finally their installation to the detector. At the moment, a final design on how to instrument the 20-inch PMTs is determined, and the instrumentation procedure is partly started. In this poster, the current status of the 20-inch PMT instrumentation for JUNO will be presented.

description: We present detailed chemical analyses for a sample of twelve stars selected from the CH star catalogue of Bartkevicius (1996). The sample includes two confirmed binaries, four objects that are known to show radial velocity variations and the rest with no information on the binary status. A primary objective is to examine if all these objects exhibit chemical abundances characteristics of CH stars, based on detailed chemical composition study using high resolution spectra. We have used high resolution (R ~ 42000) spectra from the ELODIE archive. These spectra cover 3900 to 6800 Angstrom in the wavelength range. We have estimated the stellar atmospheric parameters, the effective temperature Teff, the surface gravity log g, and metallicity [Fe/H] from LTE analysis using model atmospheres. Estimated temperatures of these objects cover a wide range from 4200 K to 6640 K, the surface gravity from 0.6 to 4.3 and metallicity from -0.13 to -1.5. We report updates on elemental abundances for several heavy elements, Sr, Y, Zr, Ba, La, Ce, Pr, Nd, Sm, Eu and Dy. For the object HD 89668 we present the first abundance analyses results. Enhancement of heavy elements relative to Fe, a characteristic property of CH stars is evident from our analyses in case of four objects, HD 92545, HD 104979, HD 107574 and HD 204613. A parametric model based study is performed to understand the relative contributions from the s- and r-process to the abundances of the heavy elements.

description: Several problems regarding the process of galaxy formation are still open. One of them is the role played by AGN phenomena in contributing to galaxy build-up and to Star Formation (SF) quenching. On the other hand, the theory of AGN formation predicts these phenomena to be correlated with the host-galaxy environment, thus opening for links between SF quenching, environment and AGN phenomena in the galaxy formation paradigm. This work is focused on the study of the correlation between environmental density and radio AGN presence. Using data from the photometric COSMOS survey and the radio 1.4GHz VLA-COSMOS, a sample of radio AGNs has been defined. The environment has been studied throughout the use of the richness distributions inside a parallelepipedon with base side of 1 Mpc and height proportional to the photometric redshift precision. Richness distributions have been compared as a function of both the redshift and the relative evolution of the stellar masses of galaxies and AGN hosts up to $z=2$. Radio AGNs are always located in environments that are significantly denser than those around galaxies in which radio emission is absent. Therefore, the environment seems to enhance the probability of a galaxy to host a radio AGN. Moreover, a distinction between high power and low power radio AGNs leads to the conclusion that the significance in the environmental effect is maintained only for low power radio sources. By studying the evolution of stellar masses it is possible to conclude that radio AGN presence is a phenomenon related to quiescent galaxies up to $z=2$, with a significant increase of the fraction of quiescent galaxies hosting a radio AGN with decreasing redshift. Hints of an environmental effect are present. The results found with this work lead to conclude that denser environments play a significant role in enhancing the probability of a galaxy to host a low power radio AGN.

description: The no-hair theorem postulates that the only externally observable properties of a black hole are its mass, its electric charge, and its angular momentum. In scalar-tensor theories of gravity, a matter distribution around a black hole can lead to the so called "spontaneous scalarisation" instability that triggers the development of scalar hair. In the Brans-Dicke type theories, this effect can be understood as a result of tachyonic effective mass of the scalar field. Here we consider the instability in the generalised class of scalar-theories that feature non-conformal, i.e. "disformal", couplings to matter. Such theories have gained considerable interest in the recent years and have been studied in a wide variety of systems, both cosmological and astrophysical. In view of the prospects of gravitational wave astronomy, it is relevant to explore the implications of the theories in the strong-gravity regime. In this article, we concentrate on the spontaneous scalarisation of matter configurations around Schwarzschild and Kerr black holes. We find that in the more generic scalar-tensor theories, the instability of the Brans-Dicke theory can be enhanced, suggesting violations of the no-hair theorem. On the other hand, we find that, especially if the coupling is very strong, or if the gradients in the matter distribution are negligible, the disformal coupling tends to stabilise the system.

The effect of noise correlations on randomized benchmarking

description: Among the most popular and well studied quantum characterization, verification and validation techniques is randomized benchmarking (RB), an important statistical tool used to characterize the performance of physical logic operations useful in quantum information processing. In this work we provide a detailed mathematical treatment of the effect of temporal noise correlations on the outcomes of RB protocols. We provide a fully analytic framework capturing the accumulation of error in RB expressed in terms of a three-dimensional random walk in "Pauli space." Using this framework we derive the probability density function describing RB outcomes (averaged over noise) for both Markovian and correlated errors, which we show is generally described by a gamma distribution with shape and scale parameters depending on the correlation structure. Long temporal correlations impart large nonvanishing variance and skew in the distribution towards high-fidelity outcomes -- consistent with existing experimental data -- highlighting potential finite-sampling pitfalls and the divergence of the mean RB outcome from worst-case errors in the presence of noise correlations. We use the Filter-transfer function formalism to reveal the underlying reason for these differences in terms of effective coherent averaging of correlated errors in certain random sequences. We conclude by commenting on the impact of these calculations on the utility of single-metric approaches to quantum characterization, verification, and validation.

Calibration of Li2100MoO4 bolometers with 56Co sources for searches of 0n2b decay of 100Mo

name: Zarytskyy, Mykola
Publisher: name: Zenodo
Year: 2020

description: CUPID-Mo is a demonstrator, located in the Modane underground laboratory, for the future ton-scale double beta decay experiment CUPID. CUPID-Mo uses an array of 20 100Mo-enriched Li2100MoO4 low-temperature scintillating bolometers. The detectors exhibit extremely high energy resolution (FWHM~6 keV for 2615 keV gamma-quanta), but a precise calibration and an accurate determination of the resolution at the Q-value of 100Mo (3034 keV) is not possible with ordinary 232Th sources. Therefore, we are going to use a 56Co source, that has several gamma-quanta with energies in the region of interest, for the energy calibration of the detectors. The detector response has been simulated to optimize the position and activity of the source so that the total counting rate does not exceed 1/6 Hz. The results of the Monte Carlo simulations will be presented.
Stabilizing Non-Hermitian Systems by Periodic Driving

description: The time evolution of a system with a time-dependent non-Hermitian Hamiltonian is in general unstable with exponential growth or decay. A periodic driving field may stabilize the dynamics because the eigenphases of the associated Floquet operator may become all real. This possibility can emerge for a continuous range of system parameters with subtle domain boundaries. It is further shown that the issue of stability of a driven non-Hermitian Rabi model can be mapped onto the band structure problem of a class of lattice Hamiltonians. As an application, we show how to use the stability of driven non-Hermitian two-level systems (0-dimension in space) to simulate a spectrum analogous to Hofstadter's butterfly that has played a paradigmatic role in quantum Hall physics. The simulation of the band structure of non-Hermitian superlattice potentials with parity-time reversal symmetry is also briefly discussed.

Cosmic muon distributions at the Sea level obtained by CORSIKA code using different models

Publisher: name: Zenodo
Year: 2020

description: We present a study of cosmic proton interactions with air in the atmosphere using COsmic Ray SImulation for KAscade (CORSIKA) code. The CORSIKA simulation uses various hadronic interactions models for the secondary particle production in the air. The secondary particles mostly pions and kaons decay to muons which finally reach the Earth. The muon energy and zenith angle distributions are then obtained with CORSIKA code using different hadronic interaction models. The muon distributions are then compared with the experimental data measured at the Sea level. CORSIKA is very efficient in producing muon distribution at the Sea level and gives a good description of experimental data although it underestimates the muon flux in low energy region. The SIBYLL and GHEISHA gives the best description of the measured vertical muon momentum distribution and muon distribution at higher zenith angles.

CUPID-Mo, first sensitivity estimates for 2νββ(0νββ) decay of 100Mo to excited states
Creators: name: Dixon, Toby
Publisher: name: Zenodo
Year: 2020

description: CUPID-Mo is a demonstrator experiment for CUPID, a proposed next generation ton-scale 0νββ search. CUPID-Mo, located in Laboratoire Souterrain de Modane, consists of an array of 20 ~0.2kg enriched Li$_2$$^{100}$Mo0$_4$ scintillating cryogenic calorimeters with 20 Ge wafer light detectors for alpha and beta/gamma particle discrimination. Whilst CUPID-Mo aims to have leading sensitivity for 0νββ to the ground state of Ru1, there is also the potential to measure 2(0)νββ to excited states by looking at coincidences with gamma de-excitations. An excellent energy resolution of 2 - 7 keV over the full spectral range, along with good radiopurity leads us to expect a significant potential for new results. Here, we present a study of the signal efficiency and the predicted background index for various event signatures using a detailed Geant4 MC simulation.

description: We study the broad emission line blazars detected in the gamma-ray band by the Large Area Telescope onboard the Fermi satellite and with the optical spectrum studied by Shaw et al. (2012, 2013). The observed broad line strength provides a measure of the ionizing luminosity of the accretion disk, while the gamma-luminosity is a proxy for the bolometric non-thermal beamed jet emission. The resulting sample, composed by 217 blazars, is the best suited to study the connection between accretion and jet properties. We compare the broad emission line properties of these blazars with those of radio-quiet and radio-loud quasars present in the Sloan Digital Sky Survey, to asses differences and similarities of the disc luminosity and the virial black hole mass. For most sources, we could derive the black hole mass by reproducing the IR-optical-UV data with a standard accretion disc spectrum, and we compared the black hole masses derived with the two methods. The distributions of the masses estimated in the two ways agree satisfactorily. We then apply a simple, one-zone, leptonic model to all the 217 objects of our sample. The knowledge of the black hole mass and disc luminosity helps to constrain the jet parameters. On average they are similar to what found by previous studies of smaller samples of sources.

description: Leucyl-tRNA synthetase (LeuRS) is clinically validated molecular target for antibiotic development. Recently, we have reported several classes of small-molecular inhibitors targeting aminoacyl-adenylate binding site ofMycobacterium tuberculosisLeuRS with antibacterial activity. In this work we performedinsilicosite-directed mutagenesis ofM. tuberculosisLeuRS synthetic site in order to identify the most critical amino acid residues for the interaction with substrate and prove binding modes of inhibitors. We carried out 20-ns molecular dynamics (MD) simulations and used umbrella sampling (US) method for the calculation of the binding free energy(ΔGb) of leucyl-adenylate with wild type and mutated forms of LeuRS.According to molecular modeling results it was found that His89, Tyr93 and Glu660 are essential amino acid residues both for aminoacyl-adenylate affinity and hydrogen bond formation. We have selected His89 for experimental site-directed mutagenesis since according to our previous molecular docking results this amino acid residue was predicted to be important for inhibitor interaction in adenine-binding region. We obtained recombinant mutantM. tuberculosisLeuRS H89A. Using aminoacylation assay we have found that the mutation of His89 to Ala in the active site ofM. tuberculosisLeuRS results in significant decrease of inhibitory activity for compounds belonging to three different chemical classes – 3-phenyl-5-(1-phenyl-1H-[1,2,3]triazol-4-yl)-[1,2,4]oxadiazoles,N-benzylidene-N'-thiazol-2-yl-hydrazines and 1-oxo-1H-isothiochromene-3-carboxylic acid (4-phenyl-thiazol-2-yl)-amide derivatives. Therefore, the interaction with His89 should be taken into account during furtherM. tuberculosisLeuRS inhibitors development and optimization.

description: A novel topology for a high gain two-stage amplifier is proposed. The proposed circuit is designed in a way that the non-dominant pole is at output of the first stage. A positive capacitive feedback (PCF) around the second stage introduces a left half plane (LHP) zero which cancels the phase shift introduced by the non-dominant pole, considerably. The dominant pole is at the output node which means that increasing the load capacitance has minimal effect on stability. Moreover, a simple and effective method is proposed to enhance slew rate. Simulation shows that slew rate is improved by a factor of 2.44 using the proposed method. The proposed amplifier is designed in a 0.18um CMOS process. It consumes 0.86mW power from a 1.8V power supply and occupies 3038.5um2 of chip area. The DC gain is 82.7dB and gain bandwidth (GBW) is 88.9 MHz when driving a 5pF capacitive load. Also low frequency CMRR and PSRR+ are 127dB and 83.2dB, respectively. They are 24.8dB and 24.2dB at GBW frequency, which are relatively high and are other important properties of the proposed amplifier. Moreover, Simulations show convenient performance of the circuit in process corners and also presence of mismatch.

description: Based on large optical and mid-infrared (IR) surveys, we investigate the relation between nuclear activity in local Seyfert 2 galaxies and galaxy interactions using a statistical neighbour counting technique. At the same level of host galaxy star formation (SF), we find that active galactic nuclei (AGNs) with stronger [OIII] emission lines do not show an excess of near neighbours, while AGNs with stronger mid-IR emission do have more near neighbours within a projected distance of 100 kpc. The excess neighbour count increases with decreasing projected radius. These results suggest a phase of torus formation during galaxy interactions.

description: We develop a new dispersion minimizing compact finite difference scheme for the Helmholtz equation in 2 and 3 dimensions. The scheme is based on a newly developed ray theory for difference equations. A discrete Helmholtz operator and a discrete operator to be applied to the source and the wavefields are constructed. Their coefficients are piecewise polynomial functions of $hk$, chosen such that phase and amplitude errors are minimal. The phase errors of the scheme are very small, approximately as small as those of the 2-D quasi-stabilized FEM method and substantially smaller than those of alternatives in 3-D, assuming the same number of gridpoints per wavelength is used. In numerical experiments, accurate solutions are obtained in constant and smoothly varying media using meshes with only five to six points per wavelength and wave propagation over hundreds of wavelengths. When used as a coarse level discretization in a multigrid method the scheme can even be used with downto three points per wavelength. Tests on 3-D examples with up to $10^8$ degrees of freedom show that with a recently developed hybrid solver, the use of coarser meshes can lead to corresponding savings in computation time, resulting in good simulation times compared to the literature.

First results from BASKET innovative bolometers for the CEνNS detection
Creators: name: Mauri, Beatrice
Publisher: name: Zenodo
Year: 2020

description: BASKET (Bolometers At Sub KeV Energy Threshold) is an R&D aiming at the development of innovative detectors for the measurement of the Coherent Elastic Neutrino-Nucleus Scattering, an interaction characterized by a cross-section 10 to 1000 times greater than the neutrino physics standard detection channels. The only experimental signature is a low energy nuclear recoil (10 to 100eV). BASKET is facing the challenge to develop very sensitive bolometric detectors, maintaining a background noise below the expected signal while being operated in close vicinity of a nuclear reactor in aboveground conditions. For this reason, several developments are required to reach an energy threshold of the order of 10eV and a response time in the range of 0.1-1ms to have a reasonable dead time and effectively discriminate the background. I will show first results about investigating and evaluating the performances of different thermal sensors coupled to Li2WO4 crystals.

description: This paper investigates the role of human agency in 40 phases of regional economic development in 12 Nordic regions over 30 years. It contributes with a theoretical framework to study agency over time and a fuzzy-set qualitative comparative analysis based on a unique dataset combining over 200 interviews, with printed and online sources, and quantitative data. The paper identifies which combinations of agency types and context conditions make industrial upgrading or diversification possible, and investigates how such combinations come into being. The causal claims from this analysis are illustrated with empirical examples and discussed in relation to previous literature.

description: We use weak gravitational lensing to measure mean mass profiles around locally brightest galaxies (LBGs). These are selected from the Seventh Data Release of the Sloan Digital Sky Survey spectroscopic and photometric catalogues to be brighter than any neighbour projected within 1.0 Mpc and differing in redshift by <1000 km s−1. Most (>83 per cent) are expected to be the central galaxies of their dark matter haloes. Previous stacking analyses have used this LBG sample to measure mean Sunyaev–Zeldovich flux and mean X-ray luminosity as a function of LBG stellar mass. In both cases, a simulation of the formation of the galaxy population was used to estimate effective halo mass for LBGs of given stellar mass, allowing the derivation of scaling relations between the gas properties of haloes and their mass. By comparing results from a variety of simulations to our lensing data, we show that this procedure has significant model dependence reflecting: (i) the failure of any given simulation to reproduce observed galaxy abundances exactly; (ii) a dependence on the cosmology underlying the simulation; and (iii) a dependence on the details of how galaxies populate haloes. We use our lensing results to recalibrate the scaling relations, eliminating most of this model dependence and explicitly accounting both for residual modelling uncertainties and for observational uncertainties in the lensing results. The resulting scaling relations link the mean gas properties of dark haloes to their mass over an unprecedentedly wide range, 1012.5 < M500/M⊙ < 1014.5, and should fairly and robustly represent the full halo population.
Galactic Center Excess in Gamma Rays from Annihilation of Self-Interacting Dark Matter

description: Observations by the Fermi-LAT telescope have uncovered a significant $γ$-ray excess toward the Milky Way Galactic Center. There has been no detection of a similar signal in the direction of the Milky Way dwarf spheroidal galaxies. Additionally, astronomical observations indicate that dwarf galaxies and other faint galaxies are less dense than predicted by the simplest cold dark matter models. We show that a self-interacting dark matter model with a particle mass of roughly 50 GeV annihilating to the mediator responsible for the strong self-interaction can simultaneously explain all three observations. The mediator is necessarily unstable and its mass must be below about 100 MeV in order to lower densities in faint galaxies. If the mediator decays to electron-positron pairs with a cross section on the order of the thermal relic value, then we find that these pairs can up-scatter the interstellar radiation field and produce the observed $γ$-ray excess. We show that this model is compatible with all current constraints and highlight detectable signatures unique to self-interacting dark matter models.

description: We examine the impact of flattening the government hierarchy on corporate innovation. Leveraging the change from province–city–county to province–managing–county (PMC) administrative structures in China, we use a different-in-differences research design to show that the PMC reform enhances corporate innovation. The results are robust to a battery of checks. We report that political connection, state-ownership of firms and improved government services mediate the effects of the PMC reform on corporate innovation. Moreover, in the cross-sectional analysis, we find that the impact of the PMC reform is more salient for non-state-owned firms or when a province has new leadership.
On exact linesearch quasi-Newton methods for minimizing a quadratic function

Year: 2015
Subjects: subject: Optimization and Control (math.OC)

description: This paper concerns exact linesearch quasi-Newton methods for minimizing a quadratic function whose Hessian is positive definite. We show that by interpreting the method of conjugate gradients as a particular exact linesearch quasi-Newton method, necessary and sufficient conditions can be given for an exact linesearch quasi-Newton method to generate a search direction which is parallel to that of the method of conjugate gradients. We also analyze update matrices and give a complete description of the rank-one update matrices that give search direction parallel to those of the method of conjugate gradients. In particular, we characterize the family of such symmetric rank-one update matrices that preserve positive definiteness of the quasi-Newton matrix. This is in contrast to the classical symmetric-rank-one update where there is no freedom in choosing the matrix, and positive definiteness cannot be preserved. The analysis is extended to search directions that are parallel to those of the preconditioned method of conjugate gradients in a straightforward manner.

Spin-current diode with a ferromagnetic semiconductor

description: Diode is a key device in electronics: the charge current can flow through the device under a forward bias, while almost no current flows under a reverse bias. Here we propose a corresponding device in spintronics: the spin-current diode, in which the forward spin current is large but the reversed one is negligible. We show that the lead/ferromagnetic quantum dot/lead system and the lead/ferromagnetic semiconductor/lead junction can work as spin-current diodes. The spin-current diode, a low dissipation device, may have important applications in spintronics, as the conventional charge-current diode does in electronics.

description: The pair distribution function of nitrogen atoms in GaAs0.983N0.017 has been determined by scanning tunneling microscopy. Nitrogen atoms in the first and third planes relative to the cleaved (110) surface are imaged. A modest enhancement in the number of nearest-neighbor pairs particularly with [001] orientation is found, although at larger separations the distribution of N pair separations is found to be random.

description: We present a design of an r.f. trap using planar electrodes with the goal to trap on the order of 100 ions in a small ring structure of diameters ranging between 100 $μ$m and 200 $μ$m. In order to minimize the influence of trap electrode imperfections due to the fabrication, we aim at trapping the ions around 400 $μ$m above the trap electrodes. In view of experiments to create freely rotating crystals near the ground state, we numerically study factors breaking the rotational symmetry such as external stray electric fields, local charging of the trap electrodes, and fabrication imperfections. We conclude that these imperfections can be controlled sufficiently well under state-of-the-art experimental conditions to allow for freely rotating ion rings even at energies comparable to the ground state energy of the rotational degree-of-freedom.

Atomic-Scale Mapping of Thermoelectric Power on Graphene: Role of Defects and Boundaries

description: The spatially resolved thermoelectric power is studied on epitaxial graphene on SiC with direct correspondence to graphene atomic structures by a scanning tunneling microscopy (STM) method. A thermovoltage arises from a temperature gradient between the STM tip and the sample, and variations of thermovoltage are distinguished at defects and boundaries with atomic resolution. The epitaxial graphene has a high thermoelectric power of 42 µV/K with a big change (9.6 µV/K) at the monolayer-bilayer boundary. Long-wavelength oscillations are revealed in thermopower maps which correspond to the Friedel oscillations of electronic density of states associated with the intravalley scattering in graphene. On the same terrace of a graphene layer, thermopower distributions show domain structures that can be attributed to the modifications of local electronic structures induced by microscopic distortions (wrinkles) of graphene sheet on the SiC substrate. The thermoelectric power, the electronic structure, the carrier concentration, and their interplay are analyzed on the level of individual defects and boundaries in graphene.
