description: Bilayer graphene (BLG) at the charge neutrality point (CNP) is strongly susceptible to electronic interactions, and expected to undergo a phase transition into a state with spontaneous broken symmetries. By systematically investigating a large number of singly- and doubly-gated bilayer graphene (BLG) devices, we show that an insulating state appears only in devices with high mobility and low extrinsic doping. This insulating state has an associated transition temperature Tc~5K and an energy gap of ~3 meV, thus strongly suggesting a gapped broken symmetry state that is destroyed by very weak disorder. The transition to the intrinsic broken symmetry state can be tuned by disorder, out-of-plane electric field, or carrier density.

description: We blend together continuum elasticity and first principles calculations to measure by a computer experiment the Young modulus of hydrogenated graphene. We provide evidence that hydrogenation generally leads to a much smaller longitudinal extension upon loading than in pristine graphene. Furthermore, the Young modulus is found to depend upon the loading direction for some specific conformers, characterized by an anisotropic linear elastic behavior.

description: We present a study on Spectral Energy Distributions, Morphologies, and star formation for an IRAC-selected extremely red object sample in the GOODS Chandra Deep Field-South. This work was enabled by new HST/WFC3 near-IR imaging from the CANDELS survey as well as the deepest available X-ray data from Chandra 4 Ms observations. This sample consists of 133 objects with the 3.6um limiting magnitude of [3.6] = 21.5, and is approximately complete for galaxies with M >10^{11}M_sun at 1.5 < z < 2.5. We classify this sample into two types, quiescent and star-forming galaxies, in the observed infrared color-color ([3.6]-[24] vs K-[3.6]) diagram. The further morphological study of this sample show a consistent result with the observed color classification. The classified quiescent galaxies are bulge dominated and star-forming galaxies in the sample have disk or irregular morphologies. Our observed infrared color classification is also consistent with the rest-frame color (U-V vs V-J) classification. We also found that quiescent and star-forming galaxies are well separated in the nonparametric morphology parameter (Gini vs M_{20}) diagram measuring their concentration and clumpiness: quiescent galaxies have Gini coefficient higher than 0.58 and star forming galaxies have Gini coefficient lower that 0.58. We argue that the star formation quenching process must lead to or be accompanied by the increasing galaxy concentration. One prominent morphological feature of this sample is that disks are commonly seen in this massive galaxy sample at 1.5 < z < 2.5: 30% of quiescent galaxies and 70% of star forming galaxies with M >10^{11}M_sun have disks in their rest-frame optical morphologies. The prevalence of these extended, relatively undisturbed disks challenges the merging scenario as the main mode of massive galaxy formation.

description: The problem of the responsibility of the psychopath, which is discussed in this thesis, has been approached, until now, in terms of whether psychopaths are mentally ill. This approach is mentioned in the first chapter, but abandoned in favour of an inquiry into which capacities are necessary for having moral consciousness. Instead of asking whether psychopaths are sick and therefore not responsible, the sickness question is bypassed, and the inquiry centres around asking whether psychopaths, in lacking the capacities necessary for moral awareness, are not appropriate objects for responsibility-ascription. Since the final claim made in the thesis is one about the incapacities of the psychopath, some time is spent discussing the notion of an incapacity, and how it is related to different senses of "responsible". The discussion of the requirements for moral consciousness centres around the notion of imagining-being someone-else . The capacity for this kind of imagining is seen as one of the capacities possessed by a person with a conscience, and" having a conscience" is presented as a shorthand way of referring to what we do in practical moral decision-making. In order to successfully imagine being someone else, it is argued, one needs to be capable of a similar range of emotions, cares or concerns. If one has only a limited capacity for such experiences, he cannot successfully perform this imagining task, and is, therefore, unable to develop moral awareness. In the latter part of the thesis, the psychopath is shown to be incapacitated in the ways discussed earlier. His range of experiences is too narrow to allow him to be a successful imaginer. This, in turn, prevents him from developing moral consciousness, and exercising the capacities, or experiencing the feelings, associated with having a conscience. Since the psychopath cannot control these incapacities, it is concluded that he is not a fit candidate for ascriptions of moral responsibility for his anti-social actions.

description: Standard models used in academic and institutional research implement the value-added tax (VAT) as a simple consumption tax levied on consumers, implying that tax changes instantaneously translate into consumer price changes. This corresponds to immediate tax pass-though, which is, however, inconsistent with a wealth of empirical evidence for gradual pass-through. I investigate how empirically plausible pass-through dynamics affect VAT multipliers in a New-Keynesian DSGE model relative to instantaneous pass-through under the conventional modeling strategy. To this end, I propose an approach to reconcile passthrough in the model with empirical estimates, and find that short-run multipliers decline by about 50% once we account for empirically observed pass-through dynamics. Standard models thus dramatically overestimate the short-run impact of VAT changes.

description: The aim of this paper is to offer an analysis of the Christian intellectual perspective of choreutic gesture, putting forward the hypothesis that by regulating dancing, late antique bishops became spokesmen for an anthropology of gesture which on the one hand demonised all forms of performative dancing and on the other hand encouraged men to become perfect imitators of an angelic choreia in the Platonic framework. This choreia was supposed to guide the behavioural movement and schemata of men’s bodies. However, it was more than just a characteristic of a presumed Ideal City; it also had to be realised in life on earth, the anticipatory mirror image of the heavenly city.

description: The magnetic moment - a function of the electric charge form factor $F_{1}(q^{2})$ and the magnetic dipole form factor $F_{2}(q^{2})$ at zero four-momentum transfer $q^{2}$-of the ground-state $J^{P}=(3/2)^{+}$ baryon decuplet magnetic moments have been studied for many years with limited success. At present, only the magnetic moment of the $Ω^{-}$ has been accurately determined. We calculate nonperturbatively the magnetic moments of the \emph{physical baryon decuplet $J^{P}=(3/2)^{+}$} members and in particular, we obtain $μ_{Δ^{++}}= (+3.67 \pm 0.07) μ_{N}$, $μ_{Δ^{+}}= (+1.83 \pm 0.04) μ_{N}$, $μ_{Δ^{0}}= (0) μ_{N}$, and the magnetic moments of their $U$-Spin partners in terms of $Ω^{-}$ magnetic moment data.

description: We compute boundary three-point functions involving two scalars and a gauge field of arbitrary spin in the AdS vacuum of Vasiliev's higher spin gravity, for any deformation parameter λ. In the process, we develop tools for extracting scalar field equations in arbitrary higher spin backgrounds. We work in the context of hs[λ] + hs[λ] Chern-Simons theory coupled to scalar fields, and make efficient use of the associative lone-star product underlying the hs[λ] algebra. Our results for the correlators precisely match expectations from CFT; in particular they match those of any CFT with W_{\infinity}[λ] symmetry at large central charge, and with primary operators dual to the scalar fields. As this is expected to include the `t Hooft limit of the W_N minimal model CFT, our results serve as further evidence of the conjectured AdS/CFT duality between these two theories.

description: Single-layer MoS2 is an attractive semiconducting analogue of graphene that combines high mechanical flexibility with a large direct bandgap of 1.8 eV. On the other hand, bulk MoS2 is an indirect bandgap semiconductor similar to silicon, with a gap of 1.2 eV, and therefore deterministic preparation of single MoS2 layers is a crucial step towards exploiting the large direct bandgap of monolayer MoS2 in electronic, optoelectronic, and photovoltaic applications. Although mechanical and chemical exfoliation methods can be used to obtain high quality MoS2 single-layers, the lack of control in the thickness, shape, size, and position of the flakes limits their usefulness. Here we present a technique for controllably thinning multilayered MoS2 down to a single-layer two-dimensional crystal using a laser. We generate single layers in arbitrary shapes and patterns with feature sizes down to 200 nm, and show that the resulting two-dimensional crystals have optical and electronic properties comparable to that of pristine exfoliated MoS2 single layers.

description: We present Submillimeter Array observations of the massive star-forming region IRAS 20126+4104 in the millimeter continuum and in several molecular line transitions. With the SMA data, we have detected nine molecular transitions, including DCN, CH3OH, H2CO, and HC3N molecules, and imaged each molecular line. From the 1.3 mm continuum emission a compact millimeter source is revealed, which is also associated with H2O, OH, and CH3OH masers. Using a rotation temperature diagram (RTD), we derive that the rotational temperature and the column density of CH3OH are 200 K and 3.7\times 1017 cm-2, respectively. The calculated results and analysis further indicate that a hot core coincides with IRAS 20126+4104. The position-velocity diagrams of H2CO 3(0,3)-2(0,2) and HC3N 25-24 clearly present Keplerian rotation. Moreover, H2CO 3(0,3)-2(0,2) is found to trace the disk rotation for the first time.

description: In the years when Porfirio Diaz was in power in Mexico, legislation was adopted specifically to encourage foreign capital to develop a petroleum industry in that country. Therefore, foreigners were granted various concessions, including the laying aside of the traditional provision of Spanish mining law--that the subsoil remain the direct property of the nation. These policies were successful, and by the second decade of the twentieth century resulted in a rapidly growing petroleum industry entirely dominated by foreign corporations. Nationalism, particularly focused on the United States' domination of the economy, was a strong element in the Mexican Revolution which overthrew the regime of Diaz in 1910. Consequently, the successive Mexican Revolutionary Administrations of Carranza, Obregon, and Calles, in their attempts to repatriate the economy, attacked the privileges of the oil industry. The most significant step in this direction was the Constitution of 1917, which ensured that the subsoil was, once again, within the patrimony of the nation. While the Revolutionary Mexican regimes sought to make this principle a reality through various acts of legislation, the American oil industry defended its vested interests with vigour. Two approaches were utilized by the oil men in their struggle to have the offending laws eliminated, or the offensive governments destroyed: they attempted to persuade the American Government to intervene in Mexico on their behalf, and more militant oil men supplied dissident Mexicans with funds and armaments to overthrow their government. The reactions of United States administrations to these initiatives varied, with some American officials going as far as to offer every assistance to such activities. During the 1920's, however, changing attitudes towards foreign policy within both the United States and Mexico produced a tendency towards negotiation and conciliation, rather than confrontation. This development resulted in the alienation of the petroleum interests; consequently, their growing impotence made way for the negotiation of a tentative agreement between the two governments in 1923, and the acceptance of a more secure settlement in 1927.

description: We report the results of quasi-simultaneous two filter optical monitoring of two high-energy peaked blazars, 1ES 1959+650 and 1ES 2344+514, to search for microvariability and short-term variability (STV). We carried out optical photometric monitoring of these sources in an alternating sequence of B and R pass-bands, and have 24 and 19 nights of new data for these two sources, respectively. No genuine microvariability (intra-night variability) was detected in either of these sources. This non-detection of intra-night variations is in agreement with the conclusions of previous studies that high-energy peaked BL Lacs are intrinsically less variable than low-energy peaked BL Lacs in the optical bands. We also report the results of STV studies for these two sources between July 2009 and August 2010. Genuine STV is found for the source 1ES 1959+650 but not for 1ES 2344+514. We briefly discuss possible reasons for the difference between the intra-night variability behaviour of high- and low-energy peaked blazars.

description: The Mexican Revolution of 1910 was a multi-faceted phenomenon involving not only great political, economic and social change, but also an equally-significant intellectual upheaval. In the preRevolutionary years, the dictatorial rule of Porfirio Diaz found justification in a philosophy which incorporated positivist and Social Darwinist principles and which was given expression by a powerful governmental clique known as the cientifico party. In the course of the Revolution, the Mexican people freed themselves not only of Diaz himself and his cientifico cronies, but also of the philosophy which they had espoused. Among the heroes of this cultural revolt in Mexico was a group of young intellectuals who banded together between 1909 and 1914 as the Ateneo de la Juventud. This thesis examines both the positivist philosophy of the Porfiriato and the revolution in thought which was engendered by the Ateneo. In addition, it undertakes to comment generally on the political activities of both the cientificos and the members of the Ateneo, and to relate their philosophies to the social environments in which they were spawned.

description: Optimal management of thermal and energy grids with fluctuating demand and prices requires to orchestrate the generation units (GU) among all their operating modes. A hierarchical approach is proposed to control coupled energy nonlinear systems. The high level hybrid optimization defines the unit commitment, with the optimal transition strategy, and best production profiles. The low level dynamic model predictive control (MPC), receiving the set-points from the upper layer, safely governs the systems considering process constraints. To enhance the overall efficiency of the system, a method to optimal start-up the GU is here presented: a linear parameter varying MPC computes the optimal trajectory in closed-loop by iteratively linearising the system along the previous optimal solution. The introduction of an intermediate equilibrium state as additional decision variable permits the reduction of the optimization horizon,while a terminal cost term steers the system to the target set-point. Simulation results show the effectiveness of the proposed approach.
Degeneracy and ordering of the non-coplanar phase of the classical bilinear-biquadratic Heisenberg model on the triangular lattice

description: We investigate the zero-temperature behavior of the classical Heisenberg model on the triangular lattice in which the competition between exchange interactions of different orders favors a relative angle between neighboring spins in the interval (0,2pi/3). In this situation, the ground states are noncoplanar and have an infinite discrete degeneracy. In the generic case, the set of the ground states is in one to one correspondence (up to a global rotation) with the non-crossing loop coverings of the three equivalent honeycomb sublattices into which the bonds of the triangular lattice can be partitioned. This allows one to identify the order parameter space as an infinite Cayley tree with coordination number 3. Building on the duality between a similar loop model and the ferromagnetic O(3) model on the honeycomb lattice, we argue that a typical ground state should have long-range order in terms of spin orientation. This conclusion is further supported by the comparison with the four-state antiferromagnetic Potts model [describing the case when the angle between neighboring spins is equal to arccos(-1/3)], which at zero temperature is critical and in terms of the solid-on-solid representation is located exactly at the point of roughening transition. At other values of the angle between neighboring spins an additional constraint appears, whose presence drives the system into an ordered phase (unless this angle is equal to pi/2, when another constraint is removed and the model becomes trivially exactly solvable).

description: We examine 288 GRBs detected by the Fermi Gamma-ray Space Telescope's Gamma-ray Burst Monitor (GBM) that fell within the field-of-view of Fermi's Large Area Telescope (LAT) during the first 2.5 years of observations, which showed no evidence for emission above 100 MeV. We report the photon flux upper limits in the 0.1-10 GeV range during the prompt emission phase as well as for fixed 30 s and 100 s integrations starting from the trigger time for each burst. We compare these limits with the fluxes that would be expected from extrapolations of spectral fits presented in the first GBM spectral catalog and infer that roughly half of the GBM-detected bursts either require spectral breaks between the GBM and LAT energy bands or have intrinsically steeper spectra above the peak of the νFν spectra (Epk). In order to distinguish between these two scenarios, we perform joint GBM and LAT spectral fits to the 30 brightest GBM-detected bursts and find that a majority of these bursts are indeed softer above Epk than would be inferred from fitting the GBM data alone. Approximately 20% of this spectroscopic subsample show statistically significant evidence for a cut-off in their high-energy spectra, which if assumed to be due to γγ attenuation, places limits on the maximum Lorentz factor associated with the relativistic outflow producing this emission. All of these latter bursts have maximum Lorentz factor estimates that are well below the minimum Lorentz factors calculated for LAT- detected GRBs, revealing a wide distribution in the bulk Lorentz factor of GRB outflows and indicating that LAT-detected bursts may represent the high end of this distribution.

description: There is increasingly strong observational evidence that slow magnetoacoustic modes arise in the solar atmosphere. Solar magneto-seismology is a novel tool to derive otherwise directly un-measurable properties of the solar atmosphere when magnetohydrodynamic (MHD) wave theory is compared to wave observations. Here, MHD wave theory is further developed illustrating how information about the magnetic and density structure along coronal loops can be determined by measuring the frequencies of the slow MHD oscillations. The application to observations of slow magnetoacoustic waves in coronal loops is discused.

Democratization of the People's Republic of China and Military Conflict in the Taiwan Strait
Creators: name: Esteba, Mario
Publisher: name: China aktuell
Year: 2020

description: This article questions whether China’s democratization would necessarily lead to a peaceful resolution of the Taiwan Strait conflict. The belligerent character of transitional regimes and the irrelevance of the democratic peace theory to civil wars are highlighted against the prevailing vision in Washington and Taibei. From this perspective, the article presents a credible democratization scenario that could actually facilitate the outbreak of a military conflict between Beijing and Taibei. Given the nationalist attitudes of China’s population and the People’s Liberation Army and the weakness of Chinese institutions, an abrupt and foreign-promoted liberalization process is discouraged. It is suggested that the United States and Republic of China governments should therefore promote gradual political liberalization from above in China and not regard China’s democratization as the solution to the Taiwan conflict.1 (Manuscript received August 21, 2007; accepted for publication October 23, 2007)

description: The mandatory adoption of IFRS by many countries worldwide fuels the expectation that financial accounting information might become more comparable across countries. This expectation is opposed to an alternative view that stresses the importance of incentives in shaping accounting information. We provide early evidence on this debate by investigating the effects of mandatory IFRS adoption on the comparability of financial accounting information around the world. Using two comparability proxies based on De Franco et al. [2011], our results suggest that the overall comparability effect of mandatory IFRS adoption is marginal at best. To investigate the reasons for this finding, we first hand-collect data on IFRS compliance for a sample of German and Italian firms and find that firm-, region-, and country-level incentives systematically shape accounting compliance. We then use the identified compliance incentives to explain the variance in the comparability effect of mandatory IFRS adoption and find it to vary systematically with firm-level incentives, suggesting that only firms with high compliance incentives experience substantial increases in comparability.
Adiabatic quantum pumping through surface states in 3D topological insulators

description: We investigate adiabatic quantum pumping of Dirac fermions on the surface of a strong 3D topological insulator. Two different geometries are studied in detail, a normal metal -- ferromagnetic -- normal metal (NFN) junction and a ferromagnetic -- normal metal -- ferromagnetic (FNF) junction. Using a scattering matrix approach, we first calculate the tunneling conductance and then the adiabatically pumped current using different pumping mechanisms for both types of junctions. We explain the oscillatory behavior of the conductance by studying the condition for resonant transmission in the junctions and find that each time a new resonant mode appears in the transport window, the pumped current diverges. We also predict an experimentally distinguishable difference between the pumped current and the rectified current.
Technicolor with a 125 GeV Higgs Boson

description: Bosonic technicolor models accommodate fermion masses via a Higgs doublet that acquires a vacuum expectation value when technifermions condense. We point out that these models are severely constrained by vacuum stability if the Higgs boson mass is near 125 GeV, the value suggested by LHC data. The Higgs quartic coupling in bosonic technicolor is typically smaller at the weak scale than in the Standard Model, while the top quark Yukawa coupling is larger. We find that the running quartic coupling remains positive below a reasonably defined cut off only in a narrow region of the model's parameter space. This region is only slightly enlarged if one allows a metastable vacuum with a lifetime longer than the age of the universe.

Measuring the Upsilon Nuclear Modification Factor at STAR

description: Suppression of quarkonia in heavy ion collisions with respect to proton-proton collisions due to the Debye screening of the potential between the heavy quarks was hypothesized to be a signature of the Quark Gluon Plasma (QGP). However, other effects besides Debye screening, such as the statistical recombination of quark anti-quark heavy flavor pairs, or co-mover absorption can also affect quarkonia production in heavy ion collisions. Quantifying the suppression of an entire family of quarkonium mesons can give us a model dependent constraint on the temperature. The suppression of Upsilon can be quantified by calculating the Nuclear Modification factor, RAA, which is the ratio of the production in Au+Au collisions to the production in p+p scaled by the number of binary collisions. We present our results for mid-rapidity Upsilon(1S+2S+3S) production in p+p and Au+Au collisions at sqrt(sNN) = 200 GeV. The centrality dependence of RAA will be shown for the combined Upsilon(1S+2S+3S) yield.

description: Thanks to the potential they hold and the variety of their application domains, Multimedia Wireless Sensor Networks (MWSN) are forecast to become highly integrated into our daily activities. Due to the carried content nature, mainly composed of images and/or video streams with high throughput and delay constraints, Quality of Service in the context of MWSN is a crucial issue. In this paper, we propose a QoS and energy aware geographic routing protocol for MWSN: QGRP. The proposed protocol addresses bandwidth, delay and energy constraints associated with MWSN. QGRP adopts an analytical model of IEEE 802.11 Distributed Coordination Function (DCF) to estimate available bandwidth and generates loop-free routing paths.

description: Data quality on categorical attribute is a difficult problem that has not received as much attention as numerical counterpart. Our basic idea is to employ association rule for the purpose of data quality measurement. Strong rule generation is an important area of data mining. Association rule mining problems can be considered as a multi objective problem rather than as a single objective one. The main area of concentration was the rules generated by association rule mining using genetic algorithm. The advantage of using genetic algorithm is to discover high level prediction rules is that they perform a global search and cope better with attribute interaction than the greedy rule induction algorithm often used in data mining. Genetic algorithm based approach utilizes the linkage between association rule and feature selection. In this paper, we put forward a Multi objective genetic algorithm approach for data quality on categorical attributes. The result shows that our approach is outperformed by the objectives like accuracy, completeness, comprehensibility and interestingness.

description: The distributed representation of correlated multi-view images is an important problem that arise in vision sensor networks. This paper concentrates on the joint reconstruction problem where the distributively compressed correlated images are jointly decoded in order to improve the reconstruction quality of all the compressed images. We consider a scenario where the images captured at different viewpoints are encoded independently using common coding solutions (e.g., JPEG, H.264 intra) with a balanced rate distribution among different cameras. A central decoder first estimates the underlying correlation model from the independently compressed images which will be used for the joint signal recovery. The joint reconstruction is then cast as a constrained convex optimization problem that reconstructs total-variation (TV) smooth images that comply with the estimated correlation model. At the same time, we add constraints that force the reconstructed images to be consistent with their compressed versions. We show by experiments that the proposed joint reconstruction scheme outperforms independent reconstruction in terms of image quality, for a given target bit rate. In addition, the decoding performance of our proposed algorithm compares advantageously to state-of-the-art distributed coding schemes based on disparity learning and on the DISCOVER.
