description: New particles with large masses that decay into hadronically interacting particles are predicted by many models of physics beyond the Standard Model. A search for a massive resonance that decays into pairs of dijet resonances is performed using 140 fb$^{-1}$ of proton$-$proton collisions at $\sqrt{s}=13$ TeV recorded by the ATLAS detector during Run 2 of the Large Hadron Collider. Resonances are searched for in the invariant mass of the tetrajet system, and in the average invariant mass of the pair of dijet systems. A data-driven background estimate is obtained by fitting the tetrajet and dijet invariant mass distributions with a four-parameter dijet function and a search for local excesses from resonant production of dijet pairs is performed. No significant excess of events beyond the Standard Model expectation is observed, and upper limits are set on the production cross-sections of new physics scenarios.

description: Recent interest in the physics of non-perturbative light-matter coupling led to the development of solid-state cavity quantum electrodynamics setups in which the interaction energies are comparable with the bare ones. In such a regime the ground state of the coupled system becomes interaction-dependent and is predicted to contain a population of virtual excitations which, notwithstanding having been object of many investigations, remain still unobserved. In this paper we investigate how virtual electronic excitations in quantum wells modify the ground-state charge distribution, and propose two methods to measure such a cavity-induced perturbation. The first approach we consider is based on spectroscopic mapping of the electronic population at a specific location in the quantum well using localised defect states. The second approach exploits instead the photonic equivalent of a Kelvin probe to measure the average change distribution across the quantum well. We find both effects observable with present-day or near-future technology. Our results thus provide a route toward a demonstration of cavity-induced modulation of ground-state electronic properties.
How women protect their children from environmental tobacco smoke: a smoldering issue
Creators: name: Secord, Sharon Anne
Publisher: name: University of British Columbia
Year: 2009

description: A growing number of research studies conclude that exposure to environmental tobacco smoke (ETS) has an overwhelming effect on the health of children causing 400,000 episodes of childhood sickness each year in Canada. The home is the predominant site of exposure, and maternal smoking is a primary source of ETS exposure in young children. Little is known or reported about maternal efforts to protect children from ETS. This situation poses a challenge to find ways to assist women in protecting their children from ETS. The purpose of this grounded theory study was to describe the process women use to protect their children from ETS. Open-ended interviews were conducted with nine mothers who smoked or were in contact with people who smoked. The findings of this study indicated that protecting children from ETS was a complex three-phase process that involved "avoiding the judgemental gaze". In the first phase, starting out with good intentions, the women established rules to protect their children from ETS and projected themselves as "good mothers". The rules were successfully applied but in the course of everyday life, circumstances presented that tested and sometimes weakened the women's resolve to abide by their rules. In the second phase, making exceptions, rules were revised to accommodate frequently occurring transgressions or replaced with less, restrictive guidelines to appease others' needs to smoke and to be "socially acceptable". The new rules were a significant departure from the women's initial good intentions creating contradictions that they could not ignore. In the third phase, dealing with contradictions, the women used several strategies to manage the dissonance they experienced as a result of their transgressions: seeking agreement from others, minimizing the effects of ETS, hiding their smoking, ignoring health information, explaining addiction, and living in hope. The process described in this study extends our understanding of how women protect their children from ETS and provides some directions for supporting women in the challenges and difficulties they encounter.

description: We report the discovery of a substellar companion to the intermediate-mass star HD 11977 (G5 III). Radial velocities of this star have been monitored for five years with FEROS at the 1.52-m ESO and later at the 2.2-m MPG/ESO telescope in La Silla, Chile. Based on the collected data we calculated an orbital solution with a period of P=711 days, a semi-amplitude of K1=105 m/s, and an eccentricity of e=0.4. The period of the radial-velocity variation is longer than that of the estimated stellar rotation, rendering it unlikely that rotational modulation is the source of the variation in the radial velocity. This hypothesis is supported by the absence of a correlation between stellar activity indicators and radial-velocity variation. By determining a primary stellar mass of Mstar=1.91 Msun, the best-fit minimum mass of the companion and semi-major axis of the orbit are m2sini=6.54 Mjup and a2=1.93 AU, respectively. An upper limit for the mass of the companion of m2 < 65.5 Mjup has been calculated from Hipparcos astrometric measurements. Although the possibility of a brown-dwarf companion cannot be excluded, HD 11977 B is one of the few planet candidates detected around an intermediate-mass star. The progenitor main-sequence star of HD 11977 is probably an A-type star. This discovery gives an indirect evidence for planetary companions around early type main-sequence stars.

description: The presence of blueshifted absorption lines in the X-ray spectra of Black Hole Low Mass X-ray Binaries is the telltale of massive outflows called winds. These signatures are found almost exclusively in soft states of high-inclined systems, hinting at equatorial ejections originating from the accretion disk and deeply intertwined with the evolution of the outburst patterns displayed by these systems. In the wake of the launch of the new generation of X-ray spectrometers, studies of wind signatures remain mostly restricted to single sources and outbursts, with some of the recent detections departing from the commonly expected behaviors. We thus give an update to the current state of iron band absorption lines detections, through the analysis of all publicly available XMM-$Newton$-PN and $Chandra$-HETG exposures of known Black Hole Low-Mass X-ray Binary candidates. Our results agree with previous studies, with wind detections exclusively found in dipping, high-inclined sources, and almost exclusively in bright ($L_{X}>0.01L_{Edd}$) soft ($HR<0.8$) states, with blueshift values generally restricted to few 100 km s$^{-1}$. The line parameters indicate similar properties between objects and outbursts of single sources, and despite more than 20 years of data, very few sources have the HID sampling necessary to properly study the evolution of the wind during single outbursts. We provide an online tool with details of the wind signatures and outburst evolution data for all sources in the sample.

description: A new type of supersymmetric transformations of the coupled-channel radial Schroedinger equation is introduced, which do not conserve the vanishing behavior of solutions at the origin. Contrary to usual transformations, these ``non-conservative'' transformations allow, in the presence of thresholds, the construction of potentials with coupled scattering matrices from uncoupled potentials. As an example, an exactly-solvable potential matrix is obtained which provides a very simple model of Feshbach-resonance phenomenon.

description: The explosion processes of supernovae (SNe) are imprinted in their explosion geometries. Here, we study the intrinsic polarization of 15 hydrogen-rich core-collapse SNe and explore the relation with the photometric and spectroscopic properties. Our sample shows diverse properties of the continuum polarization. The polarization of most SNe has a low degree at early phases but shows a sudden rise to $\sim 1$ \% degree at certain points during the photospheric phase as well as a slow decline during the tail phase, with a constant polarization angle. The variation in the timing of peak polarisation values implies diversity in the explosion geometry: some SNe have aspherical structures only in their helium cores, while in other SNe these reach out to a significant part of the outer hydrogen envelope with a common axis from the helium core to the hydrogen envelope. Other SNe show high polarization from early phases and a change of the polarization angle around the middle of the photospheric phase. This implies that the ejecta are significantly aspherical to the outermost layer and have multi-directional aspherical structures. Exceptionally, the Type~IIL SN~2017ahn shows low polarization at both the photospheric and tail phases. Our results show that the timing of the polarization rise in Type~IIP SNe is likely correlated with their brightness, velocity and the amount of radioactive Ni produced: brighter SNe with faster ejecta velocity and a larger $^{56}$Ni mass have more extended-aspherical explosion geometries. In particular, there is a clear correlation between the timing of the polarization rise and the explosion energy, that is, the explosion asphericity is proportional to the explosion energy. This implies that the development of a global aspherical structure, e.g., a jet, might be the key to realising an energetic SN in the mechanism of SN explosions.

description: We consider the task of solving generic inverse problems, where one wishes to determine the hidden parameters of a natural system that will give rise to a particular set of measurements. Recently many new approaches based upon deep learning have arisen generating impressive results. We conceptualize these models as different schemes for efficiently, but randomly, exploring the space of possible inverse solutions. As a result, the accuracy of each approach should be evaluated as a function of time rather than a single estimated solution, as is often done now. Using this metric, we compare several state-of-the-art inverse modeling approaches on four benchmark tasks: two existing tasks, one simple task for visualization and one new task from metamaterial design. Finally, inspired by our conception of the inverse problem, we explore a solution that uses a deep learning model to approximate the forward model, and then uses backpropagation to search for good inverse solutions. This approach, termed the neural-adjoint, achieves the best performance in many scenarios.

Density scaling and anisotropy in supersonic MHD turbulence

description: We study the statistics of density for supersonic turbulence in a medium with magnetic pressure larger than the gaseous pressure. This study is motivated by molecular cloud research. Our simulations exhibit clumpy density structures, which contrast increases with the Mach number. At 10 Machs densities of some clumps are three orders of magnitude higher than the mean density. These clumps give rise to flat and approximately isotropic density spectrum corresponding to the random distribution of clumps in space. We claim that the clumps originate from our random, isotropic turbulence driving. When the contribution from those clumps is suppressed by studying logarithm of density, the density statistics exhibit scale-dependent anisotropy consistent with the models where density structures arise from shearing by Alfvén waves. It is noteworthy that originally such models were advocated for the case of low-Mach, nearly incompressible turbulence.

description: Discontinuous Galerkin (DG) methods are extensions of the usual Galerkin finite element methods. Although there are vast amount of studies on DG methods, most of them have assumed shape-regularity conditions on meshes for both theoretical error analysis and practical computations. In this paper, we present a new symmetric interior penalty DG scheme with a modified penalty term. We show that, without imposing the shape-regularity condition on the meshes, the new DG scheme inherits all of the good properties of standard DG methods, and is thus robust on anisotropic meshes. Numerical experiments confirm the theoretical error estimates obtained.

Hamiltonian formulation of gravity as a spontaneously-broken gauge theory of the Lorentz group

Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: A number of approaches to gravitation have much in common with the gauge theories of the standard model of particle physics. In this paper, we develop the Hamiltonian formulation of a class of gravitational theories that may be regarded as spontaneously-broken gauge theories of the complexified Lorentz group $SO(1,3)_C$ with the gravitational field described entirely by a gauge field valued in the Lie algebra of $SO(1,3)_C$ and a `Higgs field' valued in the group's fundamental representation. The theories have one free parameter $β$ which appears in a similar role to the inverse of the Barbero-Immirzi parameter of Einstein-Cartan theory. However, contrary to that parameter, it is shown that the number of degrees of freedom crucially depends on the value of $β$. For non-zero values of $β$, it is shown that three complex degrees of freedom propagate on general backgrounds, and for the specific values $β=\pm i$ an extension to General Relativity is recovered in a symmetry-broken regime. For the value $β=0$, the theory propagates no local degrees of freedom. A non-zero value of $β$ corresponds to the self-dual and anti-self-dual gauge fields appearing asymmetrically in the action, therefore in these models, the existence of gravitational degrees of freedom is tied to chiral asymmetry in the gravitational sector.

description: Agricultural trade liberalization offers the possibility of substantial income gains and poverty reduction in the developing world. For those gains to be realized, institutional innovations and realizations of export opportunities are crucial. Adjustment policies to foster gains from trade include initiatives to compensate losers, institutional reforms to integrate into the global trading system, and policies which facilitate resource reallocations and especially enhance investment activity, both foreign and domestic. Much can be learned from experience with structural adjustment reforms, in which substantial trade liberalization by developing countries was accompanied by numerous other reforms when successful. Agriculture is important in reforms because of the size of the agricultural sector, and because poverty reduction requires that agricultural investment be part of the overall development strategy. Good governance is key, because experience has shown that the free market left to itself will not bring about the institutional innovation nor provide the public goods necessary for equitable adjustment to occur, but corrupt governments can hinder adjustment. Timing and pace of reforms is also crucial, both to insure that institutional change keeps up with market incentives, and because the macroeconomic environment is crucial to both the need for compensation and the extent of social disruption trade liberalization can bring. The role of trade relative to other development objectives must also be kept in perspective, as meeting WTO rules or compensation schemes can be extremely costly and stall other development initiatives.

description: The electronic structure of the single molecule magnet system M[Fe(L)2]3*4CHCl3 (M=Fe,Cr; L=CH3N(CH2CH2O)2) has been studied using X-ray photoelectron spectroscopy, X-ray absorption spectroscopy, soft X-ray emission spectroscopy, and density functional calculations. There is good agreement between theoretical calculations and experimental data. The valence band mainly consists of three bands between 2 eV and 30 eV. Both theory and experiments show that the top of the valence band is dominated by the hybridization between Fe 3d and O 2p bands. From the shape of the Fe 2p spectra it is argued that Fe in the molecule is most likely in the 2+ charge state. Its neighboring atoms (O,N) exhibit a magnetic polarisation yielding effective spin S=5/2 per iron atom, giving a high spin state molecule with a total S=5 effective spin for the case of M = Fe.

Baryogenesis in the Standard Model and its Supersymmetric Extension

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

description: In this work, we classify all the effective $U(1)$ symmetries and their associated Noether charges in the Standard Model (SM) and its minimal supersymmetric extension (MSSM) from the highest scale after inflation down to the weak scale. We then demonstrate that the discovery of the violation of baryon minus lepton number ($B-L$) which pinpoints to its violation in primordial Universe at any cosmic temperature above $30$ TeV will open up a new window of baryogenesis in these effective charges above this scale. While the fast SM baryon number violation in the early Universe could be the first piece to solve the puzzle of cosmic baryon asymmetry, $(B-L)$ violation could be the second important piece. In the background of expanding Universe, there is ample opportunity for out-of-equilibrium processes to generate an asymmetry in the numerous effective charges in the SM or the MSSM, making a baryon asymmetric Universe almost unavoidable. Finally we provide examples in the SM and the MSSM where baryogenesis can proceed through out-of-equilibrium dynamics without explicitly breaking baryon nor lepton number.

description: This paper examines the structural adjustments induced as China moved from a planned economy that subsidized capital-intensive industry at the expense of agriculture to a nationally integrated market economy more fitting with China's underlying resource endowments. We argue that there were few losers in the process because of 1) a gradual implementation process that maintained transfers to the favored groups under the planned economy, such as urban industrial workers, while the market economy developed benefiting the non-favored groups, such as farmers; 2) high growth rates allowed a large portion of the economy to benefit from the overall reform process and bolstered the government's commitment to further reform; and 3) labor, the most important resource that farm households hold in China, was much less institutionally constrained than land and capital during the reform period, allowing rural workers to participate in the fast growing nonagricultural sector.

For $β\in\{1,2,4\}$ this is a consequence of the Gaussian case, however the relation holds for general $β$. We further raise the question whether there is an analogue of $β$-Dyson's Brownian motion on general electrical networks, interpolating and extrapolating the fields of eigenvalues in matrix-valued Gaussian free fields. In the case $n=2$ we give a simple construction.

description: We study the double-gluon charmonium hybrid states with various quantum numbers, each of which is composed of one valence charm quark and one valence charm antiquark as well as two valence gluons. We concentrate on the exotic quantum numbers $J^{PC} =0^{--}/0^{+-}/1^{-+}/2^{+-}/3^{-+}$ that the conventional $\bar q q$ mesons can not reach. We apply the QCD sum rule method to calculate their masses to be $7.28^{+0.38}_{-0.43}$ GeV, $5.19^{+0.36}_{-0.46}$ GeV, $5.46^{+0.41}_{-0.62}$ GeV, $4.48^{+0.25}_{-0.31}$ GeV, and $5.54^{+0.35}_{-0.43}$ GeV, respectively. We study their possible decay patterns and propose to search for the $J^{PC}=2^{+-}/3^{-+}$ states in the $D^*\bar D^{(*)}/D^{*}_s \bar D^{(*)}_s/Σ_c^* \bar Σ_c^{(*)}/Ξ_c^* \bar Ξ_c^{(\prime,*)}$ channels. Experimental investigations on these states and decay channels can be useful in classifying the nature of the hybrid state, thus serving as a direct test of QCD in the low energy sector.

description: Stochastic network-dynamics are typically assumed to be memory-less. Involving prolonged dwells interrupted by instantaneous transitions between nodes such Markov networks stand as a coarse-graining paradigm for chemical reactions, gene expression, molecular machines, spreading of diseases, protein dynamics, diffusion in energy landscapes, epigenetics and many others. However, as soon as transitions cease to be negligibly short, as often observed in experiments, the dynamics develops a memory. That is, state-changes depend not only on the present state but also on the past. Here, we establish the first thermodynamically consistent -- dissipation-preserving -- mapping of continuous dynamics onto a network, which reveals ingrained dynamical symmetries and an unforeseen kinetic hysteresis. These symmetries impose three independent sources of fluctuations in state-to state kinetics that determine the `flavor of memory'. The hysteresis between the forward/backward in time coarse-graining of continuous trajectories implies a new paradigm for the thermodynamics of active molecular processes in the presence of memory, that is, beyond the assumption of local detailed balance. Our results provide a new understanding of fluctuations in the operation of molecular machines as well as catch-bonds involved in cellular adhesion.

description: We evaluate agricultural bank management performance, focusing on the impacts of interstate banking laws on productivity change. The generalized Malmquist productivity index decomposes productivity change into technological change, technical efficiency change, and change in scale economies. While managerial productivity rose from 1982 to 1991, states that adopted the most liberal interstate banking laws experienced the most improvement in productivity. Large agricultural banks were more efficient.

description: Market conduct has become an important issue for peanut farmers. Consolidation in the first buyer market, increased imports, and political uncertainty have increased peanut producers' marketing risks. The purpose of this paper was to examine demographic differences in peanut producers' perceptions of the current marketing environment as well as their attitudes towards new marketing institutions. A standard t-test revealed that producers growing more than 250 acres of peanuts, irrigating at least 50 percent of their peanuts, and producers located in Southwest Georgia were statistically more dissatisfied with the current marketing environment and significantly more receptive to forming a new generation peanut cooperative.

description: The Gottesman-Kitaev-Preskill (GKP) encoding of a qubit into a bosonic mode is a promising bosonic code for quantum computation due to its tolerance for noise and all-Gaussian gate set. We present a toolkit for phase-space description and manipulation of GKP encodings that includes Wigner functions for ideal and approximate GKP states, for various types of mixed GKP states, and for GKP-encoded operators. One advantage of a phase-space approach is that Gaussian unitaries, required for computation with GKP codes, correspond to simple transformations on the arguments of Wigner functions. We use this fact and our toolkit to describe GKP error correction, including magic-state preparation, entirely in phase space using operations on Wigner functions. While our focus here is on the square-lattice GKP code, we provide a general framework for GKP codes defined on any lattice.

description: The market for functional foods in industrialized nations has shown rapid growth over the last decades, sales being estimated at $9 billion in 1995. The emerging market economies of Central and Eastern Europe provide a unique opportunity to study consumer behavior regarding the consumption of functional foods. This paper examines demographic and socio-economic factors affecting consumer beliefs in dietary properties of food in Bulgaria, one of the economies in transition. Estimated results are expected to provide information useful for developing marketing strategies for dietary food product marketing and assist in the formulation of policies and education programs to assure that consumers make informed choices in product selection. Educational attainment level, gender, household size, and regional variables were found to have statistically significant effects on consumer beliefs in dietary properties of food in Bulgaria.
High-energy effects on the spectrum of inflationary gravitational wave background in braneworld cosmology

description: We discuss the cosmological evolution of the inflationary gravitational wave background (IGWB) in the Randall-Sundrum single-brane model. In the braneworld cosmology, in which three-dimensional space-like hypersurface that we live in is embedded in five-dimensional anti de Sitter (AdS_5) space-time, the evolution of gravitational wave (GW) modes is affected by the non-standard expansion of the universe and the excitation of the Kaluza-Klein modes (KK-modes), which are significant in the high-energy regime of the universe. We numerically evaluate these two effects by solving the evolution equation for GWs propagating through the AdS_5 space-time. Using a plausible initial condition from inflation, we find that the excitation of KK-modes can be characterized by a simple scaling relation above the critical frequency f_crit determined from the length scale of the fifth dimension \ell. The remarkable point is that this relation generally holds as long as the matter content of the universe is described by the perfect fluid with the EOS p=wρfor 0\leq w\leq 1. The resultant scaling relation is translated into the energy spectrum of the IGWB as Ω_GW\propto f^{(3w-1)/(3w+2)} for f>f_crit. This indicates that, in the radiation dominant case (w=1/3), the two high-energy effects accidentally compensate each other and the spectrum becomes almost the same as the one predicted in the four-dimensional theory, i.e., Ω_GW\propto f^0.

description: Motivated by the recent discovery of high-temperature superconductivity in bilayer La$_3$Ni$_2$O$_7$ under pressure, we study its electronic properties and superconductivity due to strong electron correlation. Using the inversion symmetry, we decouple the low-energy electronic structure into block-diagonal symmetric and antisymmetric sectors. We find that the antisymmetric sector can be reduced to a one-band system near half filling, while the symmetric bands occupied by about two electrons are heavily overdoped individually. Using the strong coupling mean field theory, we obtain strong superconducting pairing with $B_{1g}$ symmetry in the antisymmetric sector. We propose that due to the spin-orbital exchange coupling between the two sectors, $B_{1g}$ pairing is induced in the symmetric bands, which in-turn boosts the pairing gap in the antisymmetric band and enhances the high-temperature superconductivity with a congruent $d$-wave symmetry in pressurized La$_3$Ni$_2$O$_7$.

description: In recent years, significant achievements have been made in motion planning for intelligent vehicles. However, as a typical unstructured environment, open-pit mining attracts limited attention due to its complex operational conditions and adverse environmental factors. A comprehensive paradigm for unmanned transportation in open-pit mines is proposed in this research. Firstly, we propose a multi-task motion planning algorithm, called FusionPlanner, for autonomous mining trucks by the multi-sensor fusion method to adapt both lateral and longitudinal control tasks for unmanned transportation. Then, we develop a novel benchmark called MiningNav, which offers three validation approaches to evaluate the trustworthiness and robustness of well-trained algorithms in transportation roads of open-pit mines. Finally, we introduce the Parallel Mining Simulator (PMS), a new high-fidelity simulator specifically designed for open-pit mining scenarios. PMS enables the users to manage and control open-pit mine transportation from both the single-truck control and multi-truck scheduling perspectives. The performance of FusionPlanner is tested by MiningNav in PMS, and the empirical results demonstrate a significant reduction in the number of collisions and takeovers of our planner. We anticipate our unmanned transportation paradigm will bring mining trucks one step closer to trustworthiness and robustness in continuous round-the-clock unmanned transportation.

description:
Granville and Vance Counties in North Carolina face significant challenges related to food insecurity, economic stability, and the mental health of the youth within these communities. In Vance County, 17.8% of children experience food insecurity, exceeding the state average of 14.9%, while unemployment rates in Granville (5.6%) and Vance (7.5%) surpass the state average of 4.5% (NCIPH, 2023). Additionally, 25% of students report symptoms of anxiety and depression which highlights the urgent need for early intervention (2021). Limitations in policy and funding impact efforts to reduce Adverse Childhood Experiences (ACEs), emphasizing the need for advocacy to enhance mental health support and improve resource allocation. Research indicates that students suspended between the grades 7-12 have an increased risk of incarceration by the age of 26 (Hemez et al., 2021). This emphasizes the importance of school-based interventions and data-driven policies. By fostering partnerships and implementing CQI, this initiative aims to enhance long-term health outcomes by disrupting cycles of trauma and strengthening resilience with the communities of Granville and Vance Counties. The project implements a data based coordinated strategy with uses community partnership with policy advocacy and continuous quality improvement (CQI) to decrease ACEs effects while enhancing mental well being.The initiative focuses on early intervention combined with specific support services and inclusive program design to construct resilience while decreasing disparities and enhancing long term health results.The approach focuses on creating lasting systems changes and sustainable infrastructure to tackle structural inequities which will produce better health outcomes for children and families in these rural counties.

description: Future demand projections reported in this paper indicate a steady increase in demand for outdoor recreational opportunities in U.S. regions where BLM lands are located. From a supply perspective, BLM lands represent "prime targets" for meeting increased recreational demand in the western U.S. The BLM will face the challenge of balancing increased recreation use with other multiple uses, and minimizing the negative environmental impacts of increased recreation use such as damages caused by motorized vehicles, horses and foot traffic. In the future, the BLM will also face management challenges related to financing the provision of increased recreational opportunities.
