description: We study the relevance of strange degrees of freedom for nucleon structure functions. For this purpose we employ the three flavor generalization of the collective quantization approach to the chiral soliton of the bosonized Nambu-Jona-Lasinio model. Contrary to many other soliton models the hadronic tensor is tractable in this model. By applying the Bjorken limit to the hadronic tensor we extract the leading twist contributions to the nucleon structure functions at the low energy scale at which the model is assumed to approximate QCD. After transforming to the infinite momentum frame and performing the DGLAP evolution program to these structure functions we compare with available data for deep inelastic electron-nucleon scattering.

subject: Gun control

description: Past studies on mass murder have included public mass shootings along with familicides, felony murders, and gang associated murders. While all of these instances involve the murders of four or more people, there are not many other similarities between each classification. Therefore, public mass shootings are not truly accounted for in previous studies since they are rare events as opposed to familicides. This thesis examined in depth all public mass shootings occurring from 1982 to 2012 in the U.S. Specifically, trends in overall incidents, offense characteristics, and use of weapons were analyzed. The findings indicated that mass shootings are increasing slightly with almost half of all mass shootings analyzed occurring in the past eight years. Meanwhile, the trend of mass shooting incidents was not consistent with general homicide and stranger homicide levels which have decreased over the same time period. When assessing trends in offense characteristics, the significant findings were that offenders are becoming younger, mental illness is becoming an increasing factor, and venues for mass shootings are moving away from the more common workplace shootings of the 1980s. Additionally, assault weapons or large capacity magazines were used in more than half of all cases with significant increases in fatalities, injuries, and total victim counts identified.
Black-hole evaporation, cosmic censorship, and a quantum lower bound on the Bekenstein-Hawking temperature

description: The semi-classical Hawking evaporation process of Reissner-Nordström black holes is analyzed. It is shown that this quantum mechanism may turn a near-extremal black-hole spacetime with $T_{\text{BH}}\lesssim \hbar^2/G^2M^3$ into an horizonless naked singularity, thus violating the Penrose cosmic censorship conjecture. It is therefore conjectured that, within the framework of a self-consistent quantum theory of gravity, the Bekenstein-Hawking temperature should be bounded from below by the simple relation $T_{\text{BH}}\gtrsim \hbar^2/G^2M^3$.

description: We formulate a non-linear system of equations which describe higher-spin gauge interactions of massive matter fields in 2+1 dimensional space-time and explain some properties of the deformed oscillator algebra which underlies this formulation. In particular we show that the parameter of mass $M$ of matter fields is related to the deformation parameter in this algebra.

description: Effects of Kaluza-Klein excitations associated with extra dimensions with large radius compactifications on the Fermi constant are explored. It is shown that the current precision determinations of the Fermi constant, of the fine structure constant, and of the W and Z mass put stringent constraints on the compactification radius. The analysis excludes one extra space time dimension below $\sim 1.6$ TeV, and excludes 2, 3 and 4 extra space dimensions opening simultaneously below $\sim$ 3.5 TeV, 5.7 TeV and 7.8 TeV at the $90% CL$. Implications of these results for future collider experiments are discussed.

description: We study how small open economies can engineer an escape from deflation and unemployment in a global secular stagnation. Building on the framework of Eggertsson et al. (2016), we show that the transition to full employment requires a dynamic depreciation of the exchange rate, without prejudice for domestic inflation targeting. However, if depreciation has strong income and valuation effects, the escape can be beggar thy self, raising employment but actually lowering welfare. We show that, while a relaxation in the Effective Lower Bound (ELB) can work as a means of raising employment and inflation in financially closed economies, it may have exactly the opposite effect when economies are financially open.

description: Neurofibrillary tangles (NFTs) are associated with behavioral disorders in Alzheimer’s disease, Parkinson’s disease, and in chronic traumatic encephalopathy (CTE). Research has shown that NFTs play a role in learning impairments and memory deterioration. Neurobehavioral abnormalities like these can be exacerbated by environmental factors such as zinc (Zn). Previous studies conducted in our lab have shown that excessive Zn led to increased freezing levels in animals during cued fear extinction (Railey et al., 2010). In another study that used tau mice, mice showed impaired retention in contextual fear conditioning (Hunsbergera et al., 2014). Therefore, to observe the effects of both NFTs and Zn, mice were bred to possess the P301L tau mutation; consisting of both the human microtubule associated protein tau (huMAPT) mutation and the tTA transgene, with the CaMKII activator. The tau mice were subsequently raised on 10ppm supplemented zinc water. To test the animal’s learning and memory, cued and contextual fear conditioning will be conducted at 6 months of age. Since learning and memory is impaired in the tau mice it is hypothesized that they will perform poorly in fear extinction. It is also hypothesized that zinc supplemented mice will perform poorly in the experiment, as zinc has shown to effect fear extinction in mice.

The Earned Income Tax Credit: Targeting the Poor but Crowding Out Wealth
Creators: name: Froemel, M.
name: Gottlieb, C.
Publisher: name: Faculty of Economics
Year: 2016

description: In this paper, we quantify the effects of the Earned Income Tax Credit (EITC) from a macroeconomic perspective. We use an incomplete markets model to analyze jointly the labor supply and saving responses to changes in tax credit generosity and their aggregate and distributional implications. In line with existing literature, our results show that the EITC is an effective policy instrument to raise labor force participation and provide insurance to working poor households. However, we show that the EITC also disincentivizes private savings for a large part of the population, except for the poorest transfer recipients. Furthermore, since unskilled labor supply reacts more strongly than skilled workers’ labor supply, wages for low skilled workers fall relative to high skilled workers. Whilst reducing post-tax earnings inequality, the EITC contributes to both a higher skill premium and wealth inequality. Finally, our welfare analysis suggests that EITC expansions are welfare improving for the majority of the population, both ex ante and when accounting for transitional dynamics.

Mercalli scale

description: Although earthquakes are large idiosyncratic shocks for affected regions, little is known of their impact on economic activity. Seismic events are rare, the data is crude (the Richter scale measures the magnitude but says nothing of the associated damages) and counterfactuals are often entirely absent. We suggest an innovative identification strategy to address these issues based on the so-called ’Mercalli scale’ ranks - a geophysical methodology devised to gauge seismic damages relying on a newly compiled dataset following 95 Italian provinces from 1986 to 2011 (including 22 seismic episodes) offering an ideal ground for identification. Also, we carry out counterfactuals taking advantage of ex ante identical neighboring provinces that only differ ex post in terms of damages. Contrary to conventional views, we find that the impact of seismic events on output is negligible (or even positive) including after the most devastating events.

description: The decay rate of the neutral long-lived K meson into the e+ e- e+ e- final state has been measured with the NA48 detector at the CERN SPS. Using data collected in 1999, a total of 132 events has been observed with negligible background. The total number of kaons was determined to be 5.1 x 10^10. This observation corresponds to a preliminary branching ratio of Gamma(K_L -> e+ e- e+ e-)/Gamma(K_L -> all) = (3.67 +- 0.32(stat) +- 0.23(sys) +- 0.08(norm)) x 10^-8, where the first error is statistical, the second systematic, and the third error is due to the uncertainty in the normalization.

description: For the Abner Shimony (AS) inequalities, the simplest unified forms of directions attaining the maximum quantum violation are investigated. Based on these directions, a family of Einstein-Podolsky-Rosen (EPR) steering inequalities is derived from the AS inequalities in a systematic manner. For these inequalities, the local hidden state (LHS) bounds are strictly less than the local hidden variable (LHV) bounds. This means that the EPR steering is a form of quantum nonlocality strictly weaker than Bell-nonlocality.
Ferroelectric Phase Transitions from First Principles

description: An effective Hamiltonian for the ferroelectric transition in $PbTiO_3$ is constructed from first-principles density-functional-theory total-energy and linear-response calculations through the use of a localized, symmetrized basis set of ``lattice Wannier functions.'' Preliminary results of Monte Carlo simulations for this system show a first-order cubic-tetragonal transition at 660 K. The involvement of the Pb atom in the lattice instability and the coupling of local distortions to strain are found to be particularly important in producing the behavior characteristic of the $PbTiO_3$ transition. A tentative explanation for the presence of local distortions experimentally observed above $T_c$ is suggested. Further applications of this method to a variety of systems and structures are proposed for first-principles study of finite-temperature structural properties in individual materials.

description: Competition increases firms performance. But in many industries, especially network based industries, effective competition requires the separation of firms. Separation can lead to a trade-off between technical efficiency gains from competition and losses from separation. But separation itself can be beneficial, too. We estimate the combined effect of competition and vertical separation (as well as the individual effects) for the case of US electric utility divestitures. We analyse the difference-indifference in inefficient costs between divested units and non-divested units in either restructuring or non-restructuring states. We find that for our benchmark model of technology the combined effect is virtually zero. We analyze the uncertainty about the unobserved true technology and find that this number constitutes the lower bound whereas the upper bound is $24 billion. Generally, the effect of separation itself is much larger than the effect of competition. Also, the effect of separation is positive for most models of the technology.

description: A scaling description is obtained for the $d$--dimensional random field Ising model from domains in a bar geometry. Wall roughening removes the marginality of the $d=2$ case, giving the $T=0$ correlation length $ξ\sim \exp\left(A h^{-γ}\right)$ in $d=2$, and for $d=2+ε$ power law behaviour with $ν= 2/εγ$, $h^\star \sim ε^{1/γ}$. Here, $γ= 2,4/3$ (lattice, continuum) is one of four rough wall exponents provided by the theory. The analysis is substantiated by three different numerical techniques (transfer matrix, Monte Carlo, ground state algorithm). These provide for strips up to width $L=11$ basic ingredients of the theory, namely free energy, domain size, and roughening data and exponents.

description: In virtually all countries that explicitly price carbon, its effective price, i.e. the emissions-weighted price, remains low. Our analysis focuses on the political economy of this effective price, using data on an international panel of jurisdictions over the period 1990-2012. First, we examine the decision to introduce a carbon pricing policy. Second, we shed light on its stringency. Results show that both the odds of the implementation and the stringency of the carbon pricing policy are negatively affected by the share of electricity coming from coal and the relative share of industry in the economy. The results also broadly support an environmental Kuznets curve hypothesis as gross domestic product increases both the odds of the implementation and the policy stringency. Institutional and political factors are found to influence the implementation but not the stringency of carbon pricing schemes.

description: In recent years, many survivors of campus sexual violence have come forward, and student activists have collaborated to expose campus sexual violence, yet few violence prevention researchers have focused on activists’ and activist-survivors’ challenges and perceptions of their activism work (Krause et al., 2017). This master’s thesis uses in-person interviews with 15 activists and nonactivists to explore motivators and mechanisms for, barriers to, and impacts of student activism at a large Mid-Atlantic university recently experiencing a surge in sexual violence activism. Study research questions and predictions are driven by the propositions of new social movement theory, the concept of intersectionality, and Maruna’s (2001) redemption scripts. Activists involved in this study are motivated by the University’s mismanagement of sexual violence complaints and its controversial decision to hire a new faculty member previously accused of sexual assault. Successful activism organizations value careful planning and voluntariness. Barriers to activism include students’ stress and burnout, their misconceptions about activism, and University leadership’s strong and subtle opposition to student activism. Impacts of activism at the individual level include friendships resulting from engaging in activism, redemption, and empowerment. Impacts of activism at the University and community levels include Title IX-related policy and practice reform and more on-campus resources for those impacted by sex discrimination and sexual violence. These impacts suggest a more positive college experience for students due to continued student activism. Colleges and universities should follow student activists’ lead to advance Title IX-related policy and practice. Future studies should apply this study’s theoretical framework to examine the perceptions of student activists and activist-survivors, particularly activists who are non-White, male, LGBTQ, and international students.

description: Axions are a potential dark matter candidate, which may condense and form self gravitating compact objects, called axion stars (ASs). In this work, we study for the first time head-on collisions of relativistic ASs with black holes (BHs) and neutron stars (NSs). In the case of BH-AS mergers we find that, in general, the largest scalar clouds are produced by mergers of low compactness ASs and spinning BHs. Although in most of the cases which we study the majority of the mass is absorbed by the BH within a short time after the merger, in favourable cases the remaining cloud surrounding the final BH remnant can be as large as 30% of the initial axion star mass, with a bosonic cloud mass of order ~ 0.1 M_BH and peak energy density comparable to that obtained in a superradiant build up. This provides a dynamical mechanism for the formation of long lived scalar hair, which could lead to observable signals in cases where the axion interacts with baryonic matter around the BH, or where it forms the seed of a future superradiant build up in highly spinning cases. Considering NS-AS collisions we find two possible final states (i) a BH surrounded by a (small) scalar cloud, or (ii) a stable NS enveloped in an axion cloud of roughly the same mass as the initial AS. Whilst for low mass ASs the NS is only mildly perturbed by the collision, a larger mass AS gives rise to a massive ejection of baryonic mass from the system, purely due to gravitational effects. Therefore, even in the absence of a direct axion coupling to baryonic matter, NS-AS collisions could give rise to electromagnetic observables in addition to their gravitational wave signatures.

Center vortices and confinement vs. screening

Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study adjoint and fundamental Wilson loops in the center-vortex picture of confinement, for gauge group SU(N) with general N. There are N-1 distinct vortices, whose properties, including collective coordinates and actions, we study. In d=2 we construct a center-vortex model by hand so that it has a smooth large-N limit of fundamental-representation Wilson loops and find, as expected, confinement. Extending an earlier work by the author, we construct the adjoint Wilson-loop potential in this d=2 model for all N, as an expansion in powers of $ρ/M^2$, where $ρ$ is the vortex density per unit area and M is the vortex inverse size, and find, as expected, screening. The leading term of the adjoint potential shows a roughly linear regime followed by string breaking when the potential energy is about 2M. This leading potential is a universal (N-independent at fixed fundamental string tension $K_F$) of the form $(K_F/M)U(MR)$, where R is the spacelike dimension of a rectangular Wilson loop. The linear-regime slope is not necessarily related to $K_F$ by Casimir scaling. We show that in d=2 the dilute vortex model is essentially equivalent to true d=2 QCD, but that this is not so for adjoint representations; arguments to the contrary are based on illegal cumulant expansions which fail to represent the necessary periodicity of the Wilson loop in the vortex flux. Most of our arguments are expected to hold in d=3,4 also.

For a given black hole, the equilibrium surface is determined by the charge/mass ratio of the particle. By investigating a large class of charged black holes, we find that the equilibria can be stable, marginal or unstable. We focus on the unstable equilibria which signal chaotic motions and we obtain the corresponding Lyapunov exponents $λ$. We find that although $λ$ approaches universally the horizon surface gravity $κ$ when the equilibria are close to the horizon, the proposed chaotic motion bound $λ

description: Two-particle Hanbury-Brown-Twiss (HBT) interferometry is an important probe for understanding the space-time structure of particle emission sources in high energy heavy ion collisions. We present the comparative studies of HBT radii in Pb+Pb collisions at $\sqrt{s_{\rm{NN}}}$ = 17.3 GeV with Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 19.6 GeV. To further our understanding for this specific energy regime we also compare the HBT radii for Au+Au collisions at $\sqrt{s_{\rm{NN}}}$ = 19.6 GeV with Cu+Cu collisions at $\sqrt{s_{\rm{NN}}}$ = 22.4 GeV. We have found interesting similarity in the $R_{\rm out}/R_{\rm side}$ ratio with $m_{\rm T}$ across the collision systems while comparing the data for this specific energy zone which is interesting as it acts as a bridge from SPS energy regime to the RHIC energy domain.

description: We present a simple approach to predict the main features of optical spectra affected by self-phase modulation (SPM), which is based on regarding the spectrum modification as an interference effect. A two-wave interference model is found sufficient to describe the SPM-broadened spectra of initially transform-limited or up-chirped pulses, whereas a third wave should be included in the model for initially down-chirped pulses. Simple analytical formulae are derived, which accurately predict the positions of the outermost peaks of the spectra.

description: We investigate deep inelastic scattering from He-3 and H-3 within a conventional convolution treatment of binding and Fermi motion effects. Using realistic Faddeev wave functions together with a nucleon spectral function, we demonstrate that the free neutron structure function can be extracted in deep-inelastic scattering from A=3 mirror nuclei, with nuclear effects canceling to within 2% for x < 0.85.

description: Exploiting the exogenous and regional nature of the Great East Japan Earthquake of 2011, this paper provides a systematic quantification of the role of input-output linkages as a mechanism for the propagation and amplification of shocks. We document that the disruption caused by the earthquake and its aftermaths propagated both upstream and downstream supply chains, affecting the direct and indirect suppliers and customers of disaster-stricken firms. We then use our empirical findings to obtain an estimate for the overall macroeconomic impact of the shock by taking these propagation effects into account. We find that the propagation of the shock over input-output linkages can account for a 1.2 percentage point decline in Japan�s gross output in the year following the earthquake. We interpret these findings in the context of a general equilibrium model that explicitly takes the inter-firm input-output linkages into account.
The spacetime attribute of matter

description: We propose that spacetime is fundamentally a property of matter, inseparable from it. This leads us to suggest that all properties of matter must be elevated to the same status as that of spacetime in quantum field theories of matter. We suggest a specific method for extending field theories to accomodate this, and point out how this leads to the evolution of fields through channels other than the spacetime channel.

Using a spatial econometric approach to mitigate omitted variables in stochastic frontier models: An application to Norwegian electricity distribution networks

description: An important methodological issue for the use of efficiency analysis in incentive regulation of regulated utilities is how to account for the effect of unobserved cost drivers such as environmental factors. This study combines the spatial econometric approach with stochastic frontier techniques to control for unobserved environmental conditions when measuring firms� efficiency in the electricity distribution sector. Our empirical strategy relies on the geographic location of the firms as a useful source of information that has previously not been explored in the literature. The underlying idea in our empirical proposal is to utilise variables from neighbouring firms that are likely to be spatially correlated as proxies for the unobserved cost drivers. We illustrate our approach using the data of Norwegian distribution utilities for the years 2004 to 2011. We find that the lack of information on weather and geographic conditions can likely be compensated with data from surrounding firms using spatial econometric techniques. Combining efficiency analysis and spatial econometrics methods improve the goodness-of-fit of the estimated models and, hence, more accurate (fair) efficiency scores are obtained. The methodology can also be used in efficiency analysis and regulation of other types of utility sectors.

description: Auroral emissions provide opportunities to study the tenuous atmospheres of Solar System satellites, revealing the presence and abundance of molecular and atomic species as well as their spatial and temporal variability. Far-UV aurorae have been used for decades to study the atmospheres of the galilean satellites. Here we present the first detection of Europa's visible-wavelength atomic oxygen aurora at 6300/6364 Å arising from the metastable O$(^1$D) state, observed with the Keck I and Hubble Space Telescopes while Europa was in eclipse by Jupiter on six occasions in February-April 2018. The disk-integrated O($^1$D) brightness varies from $
Scaling treatment of the random field Ising model

description: Analytic phenomenological scaling is carried out for the random field Ising model in general dimensions using a bar geometry. Domain wall configurations and their decorated profiles and associated wandering and other exponents $(ζ,γ,δ,μ)$ are obtained by free energy minimization. Scaling between different bar widths provides the renormalization group (RG) transformation. Its consequences are (1) criticality at $h=T=0$ in $d \leq 2$ with correlation length $ξ(h,T)$ diverging like $ξ(h,0) \propto h^{-2/(2-d)}$ for $d<2$ and $ξ(h,0) \propto \exp[1/(c_1γh^γ)]$ for $d=2$, where $c_1$ is a decoration constant; (2) criticality in $d = 2+ε$ dimensions at $T=0$, $h^{\ast}= (ε/2c_1)^{1/γ}$, where $ξ\propto [(s-s^{\ast})/s]^{-2ε/γ}$, $s \equiv h^γ$. Finite temperature generalizations are outlined. Numerical transfer matrix calculations and results from a ground state algorithm adapted for strips in $d=2$ confirm the ingredients which provide the RG description.

Experimental Probes of Localized Gravity: On and Off the Wall

description: The phenomenology of the Randall-Sundrum model of localized gravity is analyzed in detail for the two scenarios where the Standard Model (SM) gauge and matter fields are either confined to a TeV scale 3-brane or may propagate in a slice of five dimensional anti-deSitter space. In the latter instance, we derive the interactions of the graviton, gauge, and fermion Kaluza-Klein (KK) states. The resulting phenomenological signatures are shown to be highly dependent on the value of the 5-dimensional fermion mass and differ substantially from the case where the SM fields lie on the TeV-brane. In both scenarios, we examine the collider signatures for direct production of the graviton and gauge KK towers as well as their induced contributions to precision electroweak observables. These direct and indirect signatures are found to play a complementary role in the exploration of the model parameter space. In the case where the SM field content resides on the TeV-brane, we show that the LHC can probe the full parameter space and hence will either discover or exclude this model if the scale of electroweak physics on the 3-brane is less than 10 TeV. We also show that spontaneous electroweak symmetry breaking of the SM must take place on the TeV-brane.

Tariff Scares: Trade policy uncertainty and foreign market entry by Chinese firms

description: We estimate how a rise in uncertainty about future tariff rates impacts firm decisions to enter into and exit from export markets. Using Chinese customs transactions between 2000-2009, we exploit time-variation in product-level trade policy and find that Chinese firms are less likely to enter new foreign markets and more likely to exit from established foreign markets when their products are subject to increased trade policy uncertainty. Our analysis is based on the phenomenon of �tariff echoing" - after a tariff hike in one country, another country is likely to raise its tariff on the same product. Overall, we find that if there had been no trade policy uncertainty created by the use of contingent tariffs, Chinese entry into foreign markets would have been roughly 2 percent higher per year. We use our model to counterfactually estimate how much entry by Chinese firms over 2001-2009 was due to future trade policy certainty provided by membership in the WTO.

description: We re-examine the problem of simultaneously describing in a consistent way all radiative and leptonic decays of light mesons (V -> P gamma, P -> V gamma, P -> gamma gamma, V -> e^+ e^-). For this purpose, we rely on the Hidden Local Symmetry model in both its anomalous and non--anomalous sectors. We show that the SU(3) symmetry breaking scheme proposed by Bando, Kugo and Yamawaki, supplemented with nonet symmetry breaking in the pseudoscalar sector, allows one to reach a nice agreement with all data, except for the K^{*+/-} radiative decay. An extension of this breaking pattern allows one to account for this particular decay mode too. Considered together, the whole set of radiative decays provides a pseudoscalar mixing angle theta_P ~ -11^o and a value for theta_V which is ~ 3^o from that of ideal mixing. We also show that it is impossible, in a practical sense, to disentangle the effects of nonet symmetry breaking and those of glue inside the eta', using only light meson decays.
