description: Context. The solar chromosphere and the lower transition region is believed to play a crucial role in the heating of the solar corona. Models that describe the chromosphere (and the lower transition region), accounting for its highly dynamic and structured character are, so far, found to be lacking. This is partly due to the breakdown of complete frequency redistribution in the chromospheric layers and also because of the difficulty in obtaining complete sets of observations that adequately constrain the solar atmosphere at all relevant heights. Aims. We aim to obtain semi-empirical model atmospheres that reproduce the features of the Mg II h&k line profiles that sample the middle chromosphere with focus on a sunspot. Methods. We use spectropolarimetric observations of the Ca II 8542 A spectra obtained with the Swedish 1-m Solar Telescope (SST) and use NICOLE inversions to obtain semi-empirical model atmospheres for different features in and around a sunspot. These are used to synthesize Mg II h&k spectra using RH1.5D code, which we compare with observations taken with the Interface Region Imaging Spectrograph (IRIS). Results. Comparison of the synthetic profiles with IRIS observations reveals that there are several areas, especially in the penumbra of the sunspot, where most of the observed Mg II h&k profiles are very well reproduced. In addition, we find that supersonic hot downflows, present in our collection of models in the umbra, lead to synthetic profiles that agree well with the IRIS Mg II h&k profiles, with the exception of the line core. Conclusions. We put forward and make available four semi-empirical model atmospheres. Two for the penumbra, reflecting the range of temperatures obtained for the chromosphere, one for umbral flashes, and a model representative of the quiet surroundings of a sunspot. These are available in electronic as well as in table formats.

description: We consider the quantum evolution of classically chaotic systems in contact with surroundings. Based on $\hbar$-scaling of an equation for time evolution of the Wigner's quasi-probability distribution function in presence of dissipation and thermal diffusion we derive a semiclassical equation for quantum fluctuations. This identifies an early regime of evolution dominated by fluctuations in the curvature of the potential due to classical chaos and dissipation. A stochastic treatment of this classical fluctuations leads us to a Fokker-Planck equation which is reminiscent of Kramers' equation for thermally activated processes. This reveals an interplay of three aspects of evolution of quantum noise in weakly dissipative open systems; the reversible Liouville flow, the irreversible chaotic diffusion which is characteristic of the system itself, and irreversible dissipation induced by the external reservoir. It has been demonstrated that in the dissipation-free case a competition between Liouville flow in the contracting direction of phase space and chaotic diffusion sets a critical width in the Wigner function for quantum fluctuations. We also show how the initial quantum noise gets amplified by classical chaos and ultimately equilibrated under the influence of dissipation. We establish that there exists a critical limit to the expansion of phase space. The limit is determined by chaotic diffusion and dissipation. Making use of appropriate quantum-classical correspondence we verify the semiclassical analysis by the fully quantum simulation in a chaotic quartic oscillator.

description: We develop the effective field theory of diffusive Nambu-Goldstone (NG) modes associated with spontaneous internal symmetry breaking taking place in nonequilibrium open systems. The effective Lagrangian describing semi-classical dynamics of the NG modes is derived and matching conditions for low-energy coefficients are also investigated. Due to new terms peculiar to open systems, the associated NG modes show diffusive gapless behaviors in contrast to the propagating NG mode in closed systems. We demonstrate two typical situations relevant to the condensed matter physics and high-energy physics, where diffusive type-A or type-B NG modes appear.

description: Objective: Prospective studies on relationships between hedonic hunger and BMI (Body Mass Index) during weight management are lacking. This study examined if hedonic hunger reduced during a behavioural weight management programme, and if hedonic hunger predicted future BMI. Methods: Participants were 594 community-dwelling, UK-based adults(396 female; age 56.43 years, s.d. = 12.50, range 20–83 years); 490 participants (82.5%) had obesity. Participants were randomised to a 12- or 52-week behavioural weight management intervention (WW12 or WW52, respectively) or a brief self-help intervention (BI). Relationships between hedonic hunger and BMI over 24 months (baseline, 3, 12, 24 months) were analysed using an autoregressive cross-lagged model. Results: Hedonic hunger scores decreased from 2.71 (s.d. = .91) at baseline to 2.41 (s.d. = .88) at 3 months (p < .001, CI .22 to .38), remained reduced to 24 months, and were not affected by intervention arm at any time point (p’s>.05). Baseline hedonic hunger scores predicted 3-month scores (B = .76, SE = .03, p < .001, CI .71 to .82), 3-month scores predicted 12-month scores (B = .76, SE = .03, p < .001 CI .72 to .80), and 12-month scores predicted 24-month scores (B = .72, SE = .03, p < .001, CI .64 to .77). Higher hedonic hunger at 3 months predicted higher BMI at 12 months (B = .04, SE = .02, p = .03, CI .01 to .07) but not at 24 months (p>.05). BMI at 12 months was lower in WW52 30.87kg/m2, s.d. = 5.02) than WW12 (32.12 kg/m2, s.d. = 5.58, p = .02, CI .16 to 2.34) and BI (32.74 kg/m2, s.d. = 4.15, p = .01, CI .30 to 3.45). BMI was not affected by intervention at any other time point (p’s>.05). Conclusion: Hedonic hunger reduced during weight management irrespective of intervention. Early reductions in hedonic hunger appear to be associated with lower BMI in the medium-term. Identifying ways to reduce hedonic hunger during weight loss could aid weight management for some people.

description: The diffuse extragalactic gamma-ray background (EGRB) above 100 MeV encodes unique information about high-energy processes in the universe. Numerous sources for the EGRB have been proposed, but the two systems which are certain to make some contribution are active galaxies (blazars) as well as normal galaxies. In this paper, we evaluate the contribution to the background from both sources. The active galaxy contribution arises from unresolved blazars. We compute this contribution using the Stecker-Salamon model. For normal galaxies, the emission is due to cosmic-ray interactions with diffuse gas. Our key assumption here is that the cosmic-ray flux in a galaxy is proportional to the supernova rate and thus the massive star formation rate, quantified observationally by the cosmic star formation rate (CSFR). In addition, the existence of stars today requires a considerably higher ISM mass in the past. Using the CSFR to compute both these effects, we find that normal galaxies are responsible for a significant portion (\sim 1/3) of the EGRB near 1 GeV, but make a smaller contribution at other energies. Finally, we present a "minimal" two-component model which includes contributions from both normal galaxies and blazars. We show that the spectrum of the diffuse radiation is a key constraint on this model: while neither the blazar spectra, nor the galactic spectra, are separately optimal fits to the observed spectrum, the combined emission provides an excellent fit. We close by noting key observational tests of this two-component model, which can be probed by future gamma-ray observatories such as GLAST.

description: The vortex-like solutions are studied in the framework of the gauge model of disclinations in elastic continuum. A complete set of model equations with disclination driven dislocations taken into account is considered. Within the linear approximation an exact solution for a low-angle wedge disclination is found to be independent from the coupling constants of the theory. As a result, no additional dimensional characteristics (like the core radius of the defect) are involved. The situation changes drastically for 2πvortices where two characteristic lengths, l_ϕand l_W, become of importance. The asymptotical behaviour of the solutions for both singular and nonsingular 2πvortices is studied. Forces between pairs of vortices are calculated.

Generic "Unnecessary" Quantum Critical Points with Minimal Degrees of Freedom

description: We explore generic "unnecessary" quantum critical points with minimal degrees of freedom. These quantum critical points can be avoided with strong enough symmetry-allowed deformations of the Hamiltonian, but these deformations are irrelevant perturbations below certain threshold at the quantum critical point. These quantum critical points are hence unnecessary, but also unfine-tuned (generic). The previously known examples of such generic unnecessary quantum critical points involve at least eight Dirac fermions in both two and three spatial dimensions. In this work we seek for examples of generic unnecessary quantum critical points with minimal degrees of freedom. In particular, in three dimensional space, we identify two examples of such generic unnecessary quantum critical points. The first example occurs in a $3d$ interacting topological insulator, and it is described by $two$ $(3+1)d$ massless Dirac fermions in the infrared limit; the second example occurs in a $3d$ topological superconductor, and it is formally described only $one$ $(3+1)d$ massless Dirac fermion.

description: This paper presents some of the ethical issues encountered during a participatory action research (PAR) study with youth and the challenges and opportunities the project created for knowledge exchange (KE). The study aimed to develop ways to meaningfully engage young people in research and have them co-develop research examining youth sexual health. Members of the Youth Sexual Health Team employed and trained four youth aged 18-22 years old as Youth Co-Researchers (YCRs). Together, we examined how existing policies regarding the conduct of academic research can affect young people’s participation in research and its implications for knowledge exchange. Our study revealed that many youth do not understand their rights as research participants. To address this gap, we created the “Know Your Rights with Research” card. This handout explains in youth-friendly language the basic and fundamental rights that youth need to be aware of in order to make informed decisions about their participation in research. The “Know Your Rights with Research” handout is proving to be a valuable exchange tool in our research. We use it during the informed consent process to help explain the meaning and operationalization of informed consent, confidentiality, and anonymity, among other issues. We suggest that the “Know Your Rights with Research” handout is not solely about conducting research in an ethical manner but is also providing new opportunities for knowledge exchange with young people – a population where conventional KE strategies are not always successful.

description: The dynamics of Rydberg states of atomic hydrogen driven by elliptically polarized microwaves of frequency fulfilling 2:1 classical resonance condition is investigated both semiclassically and quantum mechanically in a simplified two-dimensional model of an atom. Semiclassical results for quasienergies of the system are shown to be in a good agreement with exact quantum data. The structures of the quantum states are found to reflect the underlying classical dynamics; especially we show the existence of nonspreading wavepackets propagating on elliptical trajectories.

description: The neutrino flux close to a supernova core contributes substantially to neutrino refraction so that flavor oscillations become a nonlinear phenomenon. One unexpected consequence is efficient flavor transformation for anti-neutrinos in a region where only neutrinos encounter an MSW resonance or vice versa. Contrary to previous studies we find that in the neutrino-driven wind the electron fraction Y_e always stays below 0.5, corresponding to a neutron-rich environment as required by r-process nucleosynthesis. The relevant range of masses and mixing angles includes the region indicated by LSND, but not the atmospheric or solar oscillation parameters.

A concrete example is provided by $Λ=0$ Regge-Teitelboim cosmology, where critical cosmology only requires subcritical matter density $(Ω_{m}<1)$, and the age of a flat matter dominated Universe gets enhanced by a factor of 9/8. Dual to the mature dilute Universe is the embryo Universe, the evolution of both is governed by $P_{eff}=-{1/9}ρ_{eff}$.

description: The $(1+3)$-dimensional Dirac equation of the fermions moving in ideal Aharonov-Bohm rings in the de Sitter expanding universe is used for deriving the exact expressions of the general relativistic partial currents and corresponding energies. In the de Sitter geometry, these quantities depend on time but these are related each other just as in the non-relativistic case or in special relativity. A specific relativistic effect is the saturation of the partial currents for high values of the total angular momentum. The total relativistic persistent current at $T=0$ takes over this property even though it is evolving in time because of the de Sitter expansion.

description: This study researches and documents the impact of the 2011 Arab Uprisings on press freedom restrictions in the Hashemite Kingdom of Jordan. Since inception, the Kingdom has vacillated between liberalization and deliberalization, which is seen, most evidently, in its relationship with the press. It is imperative to look at the history of the relationship between the government and the media in Jordan in order to understand the political, social, cultural, and economic conditions under which the media may or may not have developed in the Kingdom. In Jordan, there is a direct correlation between the sharp curtailment of press freedoms and national crises. The media has, and continues to be, infected by governmental control and, therefore, becomes an unwitting ally in the regime’s quest to protect the existing state of affairs.

We discuss the renormalization of these free energies using the short distance properties of the zero temperature heavy quark potential.

description: A new fit of diffractive parton distribution functions (DPDFs) to the HERA inclusive and jet data in diffractive deep-inelastic scattering (DDIS) at next-to-next-to-leading order accuracy (NNLO) is presented. The inclusion of the most comprehensive dijet cross section data, together with their NNLO predictions, provide enhanced constraints to the gluon component of the DPDF, which is of particular importance for diffractive PDFs. Compared to previous HERA fits, the presented fit includes the high-precision HERA-II data of the H1 collaboration, which corresponds to a 40-fold increase in luminosity for inclusive data (six-fold increase for jet data). In addition to the inclusive sample at nominal centre-of-mass energy s√=319, inclusive H1 data at 252 and 225 GeV are included. The extracted DPDFs are compared to previous DPDF fits, and are used to predict cross sections for a large number of available measurements and different observables.

description: Semiconductor $p^+ - p^- - n - p^+ - n^{++}$ structures with large junction and contact areas are treated as 1 \times 2-dimensional active media, in which self-organized pattern formation can be expected. The local bistable behavior of the structures may emanate from two different mechanisms both governed by a nonlinear current feedback-loop between the electrons and holes injected from the outer layers. By considering the device to be composed of an active subsystem with negative differential resistance and a passive resistive layer with positive differential resistance an analytical approach is suggested to understand and describe the corresponding physical mechanisms in a self-consistent way. Analytical solutions of the derived model equations allow a description of homogeneous stationary states and yield explicit expressions of the current-density vs. voltage characteristics of the whole structure and its subsystems. A stability analysis of the homogeneous states with respect to two-dimensional transversal harmonic fluctuations is performed for the two cases under study. The resulting dispersion relations allow two different types of instability. While the first one is of Ridley's type which is characteristic for any spatially extended electrical system with negative differential resistance, the second type can be considered as a solid-state analogue of Turing's instability known as a generic instability mechanism which may lead, e. g., to the formation of periodic patterns.

description: Several theories extending the Standard Model (SM) have predicted the existence of addi- tional Higgs bosons. Searches for these extra Higgs bosons have focused primarily on general two Higgs doublet models (2HDM), however models where the two Higgs doublets are extended by one additional Higgs singlet complex field (2HD+1S) are consistent with SM measurements and constraints from searches for additional Higgs bosons. Moreover, 2HD+1S models such as the next-to-minimal supersymmetric (NMSSM) models can solve the so-called μ-problem of the MSSM and comfortably accommodate the 125 GeV Higgs boson in the mass spectrum. Here a series of searches performed in CMS on possible exotic decays of the Higgs boson to a pair of pseudoscalars considering different decay channels are presented. The searches cover a wide range of masses for the pseudoscalar boson, which span from very boosted to non-boosted topologies.

description: Many fathers mitigate the harm of their smoking by physically separating their smoking from their children and child care activities. In this presentation we empirically locate smoking and masculinities to detail the highly gendered nature of the everyday places where fathers smoke. The data (including 308 participant produced photographs drawn from a study of 20 men were analyzed to describe the locations and contexts that facilitate and restrict participants’ smoking. Three thematic findings, smoking on the job, the bifurcated domestic sphere, and solitary confinement were derived to detail when and where smoking does and does not occur. Drawing on these findings, we discuss next steps for developing and disseminating father-centred tobacco reduction interventions. Guided by developments in knowledge exchange, our research activities are now focusing on engaging potential end users (fathers, partners, health care providers, other stakeholders) in knowledge broker (KB) facilitated group consultations to recommend messages/resources for smoking fathers based on research findings. Involving a KB ensures that knowledge exchange activities benefit from mutual learning among interested stakeholders, a full understanding of the intended audiences for the tobacco reduction interventions, and strong relationships with those who can ensure that our interventions reach the intended audience. We discuss the effectiveness of strategies used in this integrated KT project in engaging smoking fathers, a difficult-to-reach group at the intersections of class and changing gendered roles, and potential future directions for new tobacco reduction interventions.
Quantum Geometry and Thermal Radiation from Black Holes

description: A quantum mechanical description of black hole states proposed recently within non-perturbative quantum gravity is used to study the emission and absorption spectra of quantum black holes. We assume that the probability distribution of states of the quantum black hole is given by the ``area'' canonical ensemble, in which the horizon area is used instead of energy, and use Fermi's golden rule to find the line intensities. For a non-rotating black hole, we study the absorption and emission of s-waves considering a special set of emission lines. To find the line intensities we use an analogy between a microscopic state of the black hole and a state of the gas of atoms.

description: We present observations of the Cygnus OB2 region obtained with the Giant Metrewave Radio Telescope (GMRT) at the frequencies of 325 MHz and 610 MHz. In this contribution we focus on the study of proplyd-like objects (also known as free-floating Evaporating Gas Globules or frEGGs) that typically show an extended cometary morphology. We identify eight objects previously studied at other wavelengths and derive their physical properties by obtaining their optical depth at radio-wavelengths. Using their geometry and the photoionization rate needed to produce their radio-continuum emission, we find that these sources are possibly ionized by a contribution of the stars Cyg OB2 #9 and Cyg OB2 #22. Spectral index maps of the eight frEGGs were constructed, showing a flat spectrum in radio frequencies in general. We interpret these as produced by optically-thin ionized gas, although it is possible that a combination of thermal emission, not necessarily optically thin, produced by a diffuse gas component and the instrument response (which detects more diffuse emission at low frequencies) can artificially generate negative spectral indices. In particular, for the case of the Tadpole we suggest that the observed emission is not of non-thermal origin despite the presence of regions with negative spectral indices in our maps.

description: Precision luminosity calibration is critical to determine fundamental parameters of the standard model and to constrain or to discover beyond-the-standard-model phenomena at LHC. The luminosity determination at the LHC interaction point 5 with the CMS detector, using proton-proton collisions at 13 and 5.02 TeV during Run 2 of the LHC (2015–2018), is reported. The absolute luminosity scale is obtained using beam-separation (``van der Meer'') scans. The dominant sources of systematic uncertainty are related to the knowledge of the scale of the beam separation provided by LHC magnets and the non-factorizability between the spatial components of the proton bunch density distributions in the transverse direction. When applying the van der Meer calibration to the entire data-taking period, a substantial contribution to the total uncertainty in the integrated luminosity originates from the measurement of the linearity and stability of the CMS luminometers. The reported integrated luminosity in 2015–2016 is among the most precise luminosity measurements at bunched-beam hadron colliders. Prospects for luminosity precision for LHC Run 3 and HL-LHC are also discussed.

description: Taxes are generally not given a particularly detailed treatment as analytic concepts. Instead, thinking on taxes has tended to focus on the technical aspects of how they behave. Historians have generally dealt with taxes in two ways: the first looks at them as encapsulating a moral transaction based on duty to the state and fellow citizens; and the other treats taxes as though they were simply a tool by which the government raises revenues. The second approach does not take full appreciation of the extra-economic implications and meanings of tax transactions while the first does not actually explain how taxes work to enforce these moral obligations. Taxes affect all parties in the nation in significant but almost completely imperceptible ways. For this reason, tax relationships between citizens and the state are complicated enough; let alone the interactions between corporations and the state. The corporation was and continues to be a key structure that enables and is enabled by the nation state. Despite its long and storied history in America, it occupies an ambiguous place in American society and law. Legal thinkers have tried to understand the corporate entity as existing in an uneasy cohabitation with the individualist legal tradition in America, yet this becomes harder and harder to do as corporations have come to dominate the economic and thus legal landscapes. Legislators have come to equate conceptually corporations and citizens. This becomes problematic because of the different roles that are played by corporations and citizens, a fact that is highlighted during moments of tax reform. Nowhere is this clearer than in the case of the oil industry. After the railroads of the Gilded Age, no other industry has so completely transformed the American economy and the way of life of American citizens. Yet the tax privileges granted to the oil industry have always sparked the ire of various citizens even as they are vociferously defended by others. The arguments tend to focus on why and how taxes and tax breaks for corporations can be justified. This question is a reflection of a more significant one: what is the place of the corporation in American society? I believe that the financial crisis of the late 1960s, which provoked Nixon's tax reform of 1969, gives us some insight into how legislators have sought to grapple with this question. The arguments for and against the mineral depletion allowance in 1969 are thus indicative of a much deeper trend in American thinking on the corporation.
The Principled Pursuit of Happiness: Virtue's Role in Moral Psychology

Subjects: subject: Psychology
subject: FOS: Psychology

description: The field of moral psychology has made tremendous advances in the last two decades, spurred on by the reconsideration of many prior assumptions that undergirded its study from the beginning of the twentieth century.  These new discoveries largely involved the application of new psychological tools to the puzzles of moral judgment and decision-making, often confirming intuitions ruled out by previous models, which, in turn, needed to be revised to accommodate new evidence.  This dissertation seeks to consolidate much of this research under the umbrella concept of "virtue," showing that this idea has important motivational significance for the study of moral psychology.  This concept of virtue will be examined and demonstrated to be of import to three major areas of investigation by moral psychologists: (1) moral judgments, (2) moral decisions, and (3) moral character.  This research program will provide a framework from which to argue for a revision of many popular and expert a priori assumptions about what the boundaries of morality are and how ethics relates to happiness, and suggest additional avenues for future research.
On the Second-Order Asymptotics of the Partially Smoothed Conditional Min-Entropy & Application to Quantum Compression

description: Recently, Anshu et al. introduced "partially" smoothed information measures and used them to derive tighter bounds for several information-processing tasks, including quantum state merging and privacy amplification against quantum adversaries [arXiv:1807.05630 [quant-ph]]. Yet, a tight second-order asymptotic expansion of the partially smoothed conditional min-entropy in the i.i.d. setting remains an open question. Here we establish the second-order term in the expansion for pure states, and find that it differs from that of the original "globally" smoothed conditional min-entropy. Remarkably, this reveals that the second-order term is not uniform across states, since for other classes of states the second-order term for partially and globally smoothed quantities coincides. By relating the task of quantum compression to that of quantum state merging, our derived expansion allows us to determine the second-order asymptotic expansion of the optimal rate of quantum data compression. This closes a gap in the bounds determined by Datta and Leditzky [IEEE Trans. Inf. Theory 61, 582 (2015)], and shows that the straightforward compression protocol of cutting off the eigenspace of least weight is indeed asymptotically optimal at second order.
