description: The wedge states form an important subalgebra in the string field theory. We review and further investigate their various properties. We find in particular a novel expression for the wedge states, which allows to understand their star products purely algebraically. The method allows also for treating the matter and ghost sectors separately. It turns out, that wedge states with different matter and ghost parts violate the associativity of the algebra. We introduce and study also wedge states with insertions of local operators and show how they are useful for obtaining exact results about convergence of level truncation calculations. These results help to clarify the issue of anomalies related to the identity and some exterior derivations in the string field algebra.

description: In lean premixed combustors, flame stabilization is an important operational concern that can affect efficiency, robustness and pollutant formation. The focus of this paper is on flame lift-off and re-attachment to the nozzle of a swirl combustor. Using time-resolved experimental measurements, a data-driven approach known as cluster-based reduced order modeling (CROM) is employed to 1) isolate key flow patterns and their sequence during the flame transitions, and 2) formulate a forecasting model to predict the flame instability. The flow patterns isolated by the CROM methodology confirm some of the experimental conclusions about the flame transition mechanism. In particular, CROM highlights the key role of the precessing vortex core (PVC) in the flame detachment process in an unsupervised manner. For the attachment process, strong flow recirculation far from the nozzle appears to drive the flame upstream, thus initiating re-attachment. Different data-types (velocity field, OH concentration) were processed by the modeling tool, and the predictive capabilities of these different models are also compared. It was found that the swirling velocity possesses the best predictive properties, which gives a supplemental argument for the role of the PVC in causing the flame transition. The model is tested against unseen data and successfully predicts the probability of flame transition (both detachment and attachment) when trained with swirling velocity with minimal user input. The model trained with OH-PLIF data was only successful at predicting the flame attachment, which implies that different physical mechanisms are present for different types of flame transition. Overall, these aspects show the great potential of data-driven methods, particularly probabilistic forecasting techniques, in analyzing and predicting large-scale features in complex turbulent combustion problems.

description: The importance of studying old elliptical galaxies at redshift z ~ 1.5 is reviewed, considering both what can be learned by extending studies of the evolution of cluster galaxy scaling relations to earlier cosmic epochs, and the age-dating of old elliptical galaxies at high redshifts. Following this, the first results are provided of an on-going project to find such distant elliptical galaxies, through an investigation of the cluster environments of powerful radio sources with redshifts 1.44 < z < 1.7. These studies show a considerable excess of red galaxies in the radio sources fields, with the magnitudes (K >~ 17.5) and colours (R-K > 4) expected of old passively evolving galaxies at the radio source redshift. The red galaxy overdensities are found on two different scales around the radio sources; a pronounced small-scale peak at radial distances of

description: The existence of the Nagaoka ferromagnetism is examined in the context of the one-dimensional $U=\infty$ Hubbard model. We construct the exact quantum partition function to describe the physics of such a regime. Our calculation reveals that, while the ground state in an open chain is always spin-degenerate, in a finite size closed chain with at least one vacancy, the ground state can only be ferromagnetic when the number of electrons is less or equal to three. Our results shed more light on a very recent experimental verification of Nagaoka ferromagnetism in a quantum dot set up.
High-resolution electricity generation model demonstrates suitability of high-altitude floating solar power

Publisher: name: Elsevier
Year: 2022

description:
This paper develops a meteorological site selection algorithm to quantify the electricity generation potential of floating solar design configurations on alpine water bodies in Switzerland. Using European power market demand patterns, we estimate the technical and economic potential of 82 prospective high-altitude floating solar sites co-located with existing Swiss hydropower. We demonstrate that the amount of solar energy radiating from high-altitude Swiss water bodies could meet total national electricity demand while significantly reducing carbon emissions and addressing seasonal supply/demand deficits. We construct a global map overlaying sites on each continent where high-altitude floating solar could provide low-carbon, land-sparing electricity. Our results present a compelling motivation to develop alpine floating solar installations. However, significant innovations are still needed to couple floating solar with existing hydropower operations or low-cost energy storage. As the industry matures, high-altitude floating solar technology could become a high-value, low-carbon electricity source.
Dimensionality effects on the Holstein polaron

description: Based on a recently developed variational method, we explore the properties of the Holstein polaron on an infinite lattice in $D$ dimensions, where $ 1 \le D \le 4$. The computational method converges as a power law, so that highly accurate results can be achieved with modest resources. We present the most accurate ground state energy (with no small parameter) ever published for polaron problems, 21 digits for the one-dimensional (1D) polaron at intermediate coupling. The dimensionality effects on polaron band dispersion, effective mass, and electron-phonon (el-ph) correlation functions are investigated in all coupling regimes. It is found that the crossover to large effective mass of the higher-dimensional polaron is much sharper than the 1D polaron. The correlation length between the electron and phonons decreases significantly as the dimension increases. Our results compare favorably with those of quantum Monte Carlo, dynamical mean-field theory, density-matrix renormalization group, and the Toyozawa variational method. We demonstrate that the Toyozawa wavefunction is qualitatively correct for the ground state energy and the 2-point electron-phonon correlation functions, but fails for the 3-point functions. Based on this finding, we propose an improved Toyozawa variational wavefunction.

description: Photonic lanterns (PLs) are tapered waveguides that gradually transition from a multi-mode fiber geometry to abundle of single-mode fibers. In astronomical applications, PLs can efficiently couple multi-mode telescope lightinto a multi-mode fiber entrance and convert it into multiple single-mode beams. The output beams are highlystable and suitable for feeding into high-resolution spectrographs or photonic chip beam combiners. For instance,by using relative intensities in the output cores as a function of wavelength, PLs can enable spectroastrometry. Inaddition, by interfering beams in the output cores with a beam combiner in the backend, PLs can be used forhigh-throughput interferometric imaging. When used on an Extremely Large Telescope (ELT), with its increasedsensitivity and angular resolution, the imaging and spectroastrometric capabilities of PLs will be extended tohigher contrast and smaller angular scales. We study the potential spectroastrometry and imaging science casesof PLs on ELTs, including study of exomoons, broad-line regions of quasars, and inner circumstellar disks.

description: We replicate Meissner (2016) where debt aversion was reported for the first time in an intertemporal consumption and saving problem. While Meissner (2016) uses a German sample, our subjects are US undergraduate students. All of the main findings from the original study replicate with similar effect sizes. Additionally, we extend the original analysis by correlating a new individual index of debt aversion on individual characteristics such as gender, cognitive ability, and risk aversion. The findings suggest that gender and risk aversion are not correlated with debt aversion. However, cognitive ability is positively correlated with debt aversion. Overall, this paper confirms the importance of debt aversion in intertemporal consumption problems and validates the approach of Meissner (2016).

description: The ability to plan informative paths online is essential to robot autonomy. In particular, sampling-based approaches are often used as they are capable of using arbitrary information gain formulations. However, they are prone to local minima, resulting in sub-optimal trajectories, and sometimes do not reach global coverage. In this paper, we present a new RRT*-inspired online informative path planning algorithm. Our method continuously expands a single tree of candidate trajectories and rewires segments to maintain the tree and refine intermediate trajectories. This allows the algorithm to achieve global coverage and maximize the utility of a path in a global context, using a single objective function. We demonstrate the algorithm's capabilities in the applications of autonomous indoor exploration as well as accurate Truncated Signed Distance Field (TSDF)-based 3D reconstruction on-board a Micro Aerial vehicle (MAV). We study the impact of commonly used information gain and cost formulations in these scenarios and propose a novel TSDF-based 3D reconstruction gain and cost-utility formulation. Detailed evaluation in realistic simulation environments show that our approach outperforms state of the art methods in these tasks. Experiments on a real MAV demonstrate the ability of our method to robustly plan in real-time, exploring an indoor environment solely with on-board sensing and computation. We make our framework available for future research.

description: Recently in [Phys. Rev. B 99, 241301(R) (2019)] tensor networks build upon logical circuits were briefly introduced to retrieve exciton and biexciton states. Compared to a conventional approach the tensor network methods scales logarithmic instead of linear in the grid points of the Brioullin zone and linear instead of exponential in the number of electrons and holes. This enables calculations with higher precision on the full Brioullin zone than previously possible. In this paper extensive details for an efficient implementation and the corresponding mathematical background are presented. In particular this includes applications and results for excitons, trions and biexcitons (for monolayer MoS$_2$ as example), going beyond the initial brief introduction. Furthermore strategies for calculating selective excited bound states and tests of common approximations are discussed making use of the high accuracy full Brioullin zone treatment of the tensor network method.

A measurement strategy to address disparities across household energy burdens

Year: 2022

description:
Energy inequity is an issue of increasing urgency. Few policy-relevant datasets evaluate the energy burden of typical American households. Here, we develop a framework using Net Energy Analysis and household socioeconomic data to measure systematic energy inequity among critical groups that need policy attention. We find substantial instances of energy poverty in the United States – 16% of households experience energy poverty as presently defined as spending more than 6% of household income on energy expenditures. More than 5.2 million households above the Federal Poverty Line face energy poverty, disproportionately burdening Black, Hispanic, and Native American communities. For solar, wind, and energy efficiency to address socioeconomic mobility, programs must reduce energy expenditures by expanding eligibility requirements for support and access to improved conservation measures, efficiency upgrades, and distributed renewables. We recommend the United States develop a more inclusive federal energy poverty categorization that increases assistance for household energy costs.

The geometry of complexes and binding mode of ligand were worked out through FT-IR and NMR spectroscopies. The ligand coordinate with Sn via carboxylato oxygen in monodentate fashion leading to four coordinated geometries around Sn center. The effectiveness of complexes towards their antimicrobial and cytotoxic potential was evaluated and a significant extent of antimicrobial potential was observed with a few exceptions. Molecular docking studies were performed for these complexes to check their interaction with DNA. Results from this study revealed that these compounds can bind favorably with cisplatin binding site and targeting the major groove of DNA. The complex-DNA interaction study was also performed through UV-Vis spectroscopic technique and viscosity measurement, and the observed experimental results were well matched with theoretical results. Computational vibrational analysis, frontier molecular orbital (FMO), natural bond orbitals (NBOs), linear and non-linear optical (NLO) properties of ligand and complexes 1-3 were calculated by density functional theory (DFT) and time-dependent DFT (TDDFT) using CAM-B3LYP/6-31G (d,p) level of theory to evaluate spectroscopic, structural parameters and reactivity patterns.

We observe interesting properties regarding the transcendentality of the transversity coefficient function. Our results complete the calculation of the full next-to-next-to-leading order coefficient function in deeply virtual Compton scattering. Numerically, the two-loop corrections in the axial-vector and transversity channel are comparable to their vector counterpart at moderate skewness parameter ξ and hence indispensable for analyzing the upcoming high-precision data from the Electron-Ion Collider.

description: Transport critical current (Ic) was measured for Fe-sheathed MgB2 round wires. A critical current density of 5.3 x 10^4 A/cm^2 was obtained at 32K. Strong magnetic shielding by the iron sheath was observed, resulting in a decrease in Ic by only 15% in a field of 0.6T at 32K. In addition to shielding, interaction between the iron sheath and the superconductor resulted in a constant Ic between 0.2 and 0.6T. This was well beyond the maximum field for effective shielding of 0.2T. This effect can be used to substantially improve the field performance of MgB2/Fe wires at fields at least 3 times higher than the range allowed by mere magnetic shielding by the iron sheath. The dependence of Ic on the angle between field and current showed that the transport current does not flow straight across the wire, but meanders between the grains.

Sugar and paper firms are symbiotically connected, in the sense that the biomass from the manufacture of one product is used as a raw material for the second product, and vice versa. We characterize the firm’s operational optimal/equilibrium decisions for its two products – both in the presence and absence of a symbiotic system – under monopoly as well as under competition. Our models capture the supply-side (e.g., a fixed production cost and changes in the variable production costs), as well as the demand-side (“green” consumers who value the nature-friendly production process) impact of implementing industrial symbiosis. Our results indicate that firms are more willing to implement industrial symbiosis when (i) the proportion of the green consumers is high; or (ii) consumers’ appreciation for the green variants is high; or (iii) variable production costs after implementation are lower. For a firm, competition from firms that only produce regular products encourages implementation of industrial symbiosis, whereas competition from firms that produce both regular and green products discourages it.

description: This paper attempts to evaluate the effectiveness of the specially designed packages of water, sanitation and hygiene (WASH) interventions with ‘student brigades’ (student teams tasked with maintaining hygiene in school) on household WASH behavior and practices in both a household and farm setting. In addition, household members’ health and developmental productivity outcomes were also examined. A randomized control trial (RCT) involving student brigades (SBs) was carried out in six sub-districts (hotspots) characterized by comparatively poor WASH indicators. The specially designed WASH-agriculture treatment consisted of three interventions: (1) informing the households about the prior water testing results; (2) delivering hygiene messages with the help of posters; (3) equipping SB members with water quality test kits and asking them to test the water quality at different places and report their findings to their household. Employing the difference-in-difference (DID) multivariate regression technique, the analysis revealed that the BRAC WASH treatment performed well in terms of effecting behavioral changes and improving hygiene practices. In addition, the results suggested that informing households of their drinking water quality and conveying WASH-agriculture hygiene messages to them could have a significant incremental impact over the existing BRAC WASH treatment in changing household hygiene behavior and practices at home and on farms. This research provides evidence that students can act as agents of change in improving water quality, sanitation and health in a rural setting.

description: A particular challenge in the design of HVDC equipment is the accumulation of electrical charge carriers at gas-solid interfaces and in the bulk of the solid insulation material, which can cause locally increased electrical field stress. During operation, a current flows through the conductor, leading to an inhomogeneous temperature distribution between conductor and enclosure. Thus, the solid epoxy insulators are experiencing the whole temperature gradient. As the electric field distribution at DC voltage is mainly determined by the conductivities of the applied insulating media and the conductivity of epoxy resin is strongly temperature-dependent, the temperature distribution has a major impact on the electric field distribution and with this on the dielectric performance of the insulation system. Hence, testing of gas-insulated HVDC equipment always requires the consideration of high current and high DC voltage at the same time. An AC test current is typically used to generate the temperature gradient in the insulating system. However, the commercial operation of the HVDC equipment with DC current must be reflected, when thermo-electric tests in the laboratory are performed with AC current. This paper presents temperature-rise tests with different AC and DC test currents up to 5000 A, applied to commercial gas-insulated HVDC equipment. Based on the test data, different approaches for the determination of representative test currents for thermo-electric tests are discussed. In conclusion, a representative AC test current for the given HVDC equipment is proposed, which considers all major effects for thermo-electric testing. To reduce the practical efforts for future laboratory tests, the calculation approach for AC test currents of HVDC bushings (IEC/IEEE 65700-19-03) is evaluated with regard to a possible application to the tested gas-insulated HVDC equipment. The result is compared with the measured data. The paper shows the application of this standard to gas-insulated systems and proposes further possible optimizations.

description: Natural muscles provide mobility in response to nerve impulses. Electromyography (EMG) measures the electrical activity of muscles in response to a nerve's stimulation. In the past few decades, EMG signals have been used extensively in the identification of user intention to potentially control assistive devices such as smart wheelchairs, exoskeletons, and prosthetic devices. In the design of conventional assistive devices, developers optimize multiple subsystems independently. Feature extraction and feature description are essential subsystems of this approach. Therefore, researchers proposed various hand-crafted features to interpret EMG signals. However, the performance of conventional assistive devices is still unsatisfactory. In this paper, we propose a deep learning approach to control prosthetic hands with raw EMG signals. We use a novel deep convolutional neural network to eschew the feature-engineering step. Removing the feature extraction and feature description is an important step toward the paradigm of end-to-end optimization. Fine-tuning and personalization are additional advantages of our approach. The proposed approach is implemented in Python with TensorFlow deep learning library, and it runs in real-time in general-purpose graphics processing units of NVIDIA Jetson TX2 developer kit. Our results demonstrate the ability of our system to predict fingers position from raw EMG signals. We anticipate our EMG-based control system to be a starting point to design more sophisticated prosthetic hands. For example, a pressure measurement unit can be added to transfer the perception of the environment to the user. Furthermore, our system can be modified for other prosthetic devices.

description: We make use of two empirical relations between the black hole mass and the global properties (bulge luminosity and stellar velocity dispersion) of nearby elliptical galaxies, to infer the mass of the central black hole (M_BH) in low redshift radiogalaxies. Using the most recent determinations of black hole masses for inactive early type galaxies we show that the bulge luminosity and the central velocity dispersion are almost equally correlated (similar scatter) with the central black-hole mass. Applying these relations to two large and homogeneous datasets of radiogalaxies we find that they host black-holes whose mass ranges between ~5x10^7 to ~6x10^9 M_sun (average ~8.9). M_BH is found to be proportional to the mass of the bulge (M_bulge). The distribution of the ratio M_BH/M_bulge has a mean value of 8x10^{-4} and shows a scatter that is consistent with that expected from the associated errors. At variance with previous claims no significant correlation is instead found between M_BH (or M_bulge) and the radio power at 5GHz.

description: We study the problem of minimizing the Wasserstein distance between a probability distribution and an algebraic variety. We consider the setting of finite state spaces and describe the solution depending on the choice of the ground metric and the given distribution. The Wasserstein distance between the distribution and the variety is the minimum of a linear functional over a union of transportation polytopes. We obtain a description in terms of the solutions of a finite number of systems of polynomial equations. The case analysis is based on the ground metric. A detailed analysis is given for the two bit independence model.

Environmental impacts associated with hydrogen production in La Guajira, Colombia

description:
The global push to decarbonize sectors of the economy and phase-out coal use has attracted a renewed interest in hydrogen. At the forefront of this debate, Colombia, the world’s 6th largest coal exporter, must consider strategies to support a just transition for regions that depend economically on coal exports. However, the role of hydrogen as a part of the energy transition has yet to be examined from an environmental justice lens. A full-chain life-cycle assessment of hydrogen production is yet to be considered in Colombia. Using life-cycle assessment (LCA) methodology, we examine the greenhouse gas emissions, water consumption, and trace metal emissions associated with six potential Colombian liquid hydrogen production strategies: (1) electrolysis powered by the country’s national electricity grid, (2) on-site electrolysis powered by electricity produced by a wind farm, (3) off-site electrolysis powered by electricity produced by a wind farm, (4) electrolysis powered by electricity produced from a coal-fired power plant, (5) coal gasification without carbon capture and storage (CCS), and (6) coal gasification with CCS. Upstream conversion has an outsized influence on the sustainability of a hydrogen transition in Colombia. Impact levels for wind-powered electrolysis are lower than those of the coal- and grid-powered scenarios for every impact category analyzed, apart from emissions of aluminum to air, nitrogen emissions to water, and phosphorous, nitrate, and nitrite emissions to soil. The grid-based electrolysis scenario is found to consume the largest amount of water, while coal-fueled scenarios pathways raise concerns of greater life-cycle mercury, nickel, and arsenic emissions. While coal gasification with CCS reduced gasification CO2 emissions by 35%, the CCS scenario’s VOC emissions were 37% greater than gasification without CCS, given that increased levels of coal inputs were required to account for the loss of efficiency associated with the addition of CCS technology. For Colombia to benefit most from a hydrogen-based decarbonization transition with minimal environmental impacts, community-focused planning and wind-based hydrogen systems should be prioritized.

description: A detailed qualitative analysis and numerical modeling of the evolution of cosmological models based on nonlinear classical and phantom scalar fields with self-action are performed. Complete phase portraits of the corresponding dynamical systems and their projections onto the Poincaré sphere are constructed. It is shown that the phase trajectories of the corresponding dynamical systems can, depending on the parameters of the model of the scalar field, split into bifurcation trajectories along 2, 4, or 6 different dynamical flows. In the phase space of such systems, regions can appear which are inaccessible for motion. Here phase trajectories of the phantom scalar field wind around one of the symmetric foci (centers) while the phase trajectories of the classical scalar field can have a limit cycle determined by the zero effective energy corresponding to a Euclidean Universe.

description: Recent progresses in condensed matter physics, such as graphene, topological insulator and Weyl semimetal, often origin from the specific topological symmetries of their lattice structures. Quantum states with different degrees of freedom, e.g. spin, valley, layer, etc., arise from these symmetries, and the coherent superpositions of these states form multiple energy subbands. The pseudospin, a concept analogy to the Dirac spinor matrices, is a successful description of such multi-subband systems. When the electron-electron interaction dominates, many-body quantum phases arise. They usually have digitized pseudospin polarizations and exhibit sharp phase transitions at certain universal critical pseudospin energy splittings. In this manuscript, we present our remarkable discovery of hydrostatic pressure induced degeneracy between the two lowest Landau levels. This degeneracy is evidenced by the pseudospin polarization transitions of the fragile correlated quantum liquid phases near Landau level filling factor $ν$ = 3/2. Benefitted from the constant hole concentration and the sensitive nature of these transitions, we can study the fine-tuning effect of the hydrostatic pressure of the order of 10 $μ$eV, well beyond the meV-level state-of-the-art resolution of other techniques.
