parameterization sensitivity

Bulk microphysical (MP) parameterizations describe the processes by which water and ice particles grow and precipitate within a cloud. These schemes allow models to represent cloud processes that occur on the microscale and cannot be properly resolved. Uncertainties in climate simulations and operational forecasts remain due to the choice of MP scheme. To analyze the effect different parameterizations have on cloud processes and storm development, this study simulates a single, isolated deep convective storm occurring in a low wind shear environment using the Weather Research and Forecasting (WRF) model in idealized mode at “convection-permitting” scale (i.e., without a deep convection parameterization). WRF is initialized using an atmospheric vertical profile from the National Center of Atmospheric Research Community Climate System Model version 3 (CCSM3) averaged for the summer months (June, July, August) for 1970-1999 at Jasper, IN, USA. Four MP parameterizations available in WRF (WSM6, Thompson, Milbrandt-Yau, and Morrison) are compared at three different horizontal resolutions (2 km, 1 km, and 250 m). An analysis of storm evolution and structure is performed, including precipitation efficiency and storm dynamics. Results show large increases in surface precipitation with increasing resolution regardless of the MP parameterization, especially between 1 km and 250 m grid spacing. This occurs because of greater condensation associated with increased updraft mass flux at higher resolution. Overall differences between schemes are consistent at the various resolutions tested. Out of the four schemes, WSM6 produces the lowest precipitation amount, which results from a relatively high rain evaporation rate. This study concludes that a strong sensitivity to MP scheme and horizontal resolution exists, which can impact surface precipitation, storm structure and dynamics in model simulations.

description: We investigate the ultra-diffuse galaxy (UDG) UGC 9050-Dw1, which was selected because of its disturbed morphology as part of a larger sample of UDGs that display evidence for significant interactions. We use the Hubble Space Telescope's Advanced Camera for Surveys to identify globular clusters (GCs) associated with UGC 9050-Dw1, and the Jansky Very Large Array to measure its $\mathrm{H}\mathrm{I}$ content. UGC 9050-Dw1, a neighbor to the low surface brightness spiral UGC 9050, exhibits a unique UV bright central ``clump'' with clearly associated $\mathrm{H}{\mathrm{I}}$ gas and an extended stellar tidal plume to the north. We identify $52^{+4}_{-6}$ GCs, implying a specific frequency $S_\mathrm{N} = 122_{-24}^{+30}$, one of the highest reported for a UDG of this luminosity. Additionally, $\sim 20\%$ of the total light of the galaxy is contributed by GCs. Nearly uniform GC colors suggest they were formed during a single intense episode of star formation. We propose that UGC 9050-Dw1 formed via a rare dwarf merger event where induced, clumpy star formation led to its current observed properties.

description: The energies of the lowest $^2P_u$, $^4P_g$ and $2D_g$ states of the boron atom are calculated with $μ$hartree accuracy, in the basis of symmetrized, explicitly correlated Gaussian lobe functions. Finite nuclear mass and scalar relativistic corrections are taken into account. This study contributes to the problem of the energy differences between doublet and quartet states of boron, which have not been measured to date. It is found that the $^2P_u\rightarrow^4P_g$ excitation energy, recommended in the Atomic Spectra Database, appears underestimated by more than 300~cm$^{-1}$.

Schrödinger oscillators in a deformed point-like global monopole spacetime and a Wu-Yang magnetic monopole: position-dependent mass correspondence and isospectrality
Creators: name: Mustafa, Omar
Publisher: name: arXiv
Year: 2023
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We show that a specific transformation/deformation in a point-like global monopole (PGM) spacetime background would yield an effective position-dependent mass (PDM) Schrödinger equation (i.e., a von Roos PDM Schrödinger equation). We discuss PDM Schrödinger oscillators in a PGM spacetime in the presence of a Wu-Yang magnetic monopole. Within our transformed/deformed global monopole spacetime, we show that all PDM Schrödinger oscillators admit isospectrality and invariance with the constant mass Schrödinger oscillators in the regular global monopole spacetime in the presence of a Wu-Yang magnetic monopole. The exclusive dependence of the thermodynamical partition function on the energy eigenvalues manifestly suggests that the Schrödinger oscillators and the PDM Schrödinger oscillators share the same thermodynamical properties as mandated by their isospectrality. Moreover, we discuss the hard-wall effect on the energy levels of the PDM Schrödinger oscillators in a PGM spacetime without and with a Wu-Yang magnetic monopole. Drastic energy levels' shift-ups are observed as a consequence of such hard-wall effect.

description: In this paper, a strain gradient continuum model for a metamaterial with a periodic lattice substructure is considered. A second gradient constitutive law is postulated at the macroscopic level. The effective classical and strain gradient stiffness tensors are obtained based on asymptotic homogenization techniques using the equivalence of energy at the macro- and microscales within a so-called representative volume element. Numerical studies by means of finite element analysis were performed to investigate the effects of changing volume ratio and characteristic length for a single unit cell of the metamaterial as well as changing properties of the underlying material. It is also shown that the size effects occurring in a cantilever beam made of a periodic metamaterial can be captured with appropriate accuracy by using the identified effective stiffness tensors.

description: We present the results of millimeter and centimeter continuum observations, made with the IRAM 30m telescope and the VLA, toward a sample of 11 luminous IRAS sources classified as high-mass protostellar object candidates. We find 1.2 mm emission for all (but one) regions likely tracing the dust core in which the massive young stellar object is forming, for which we estimate masses ranging from 10 to 140 Msun. For all the sources, but one, we detect centimeter emission associated with the IRAS source, being compact or ultracompact HII region candidates, with early B-type stars as ionizing stars. The 7 mm emission is partially resolved for the four sources observed at this wavelength, with contribution of dust emission at 7 mm ranging from negligible to 44%. By combining our data with infrared surveys we fitted the spectral energy distribution of the sources. Finally, we find a correlation between the degree of disruption of the natal cloud, estimated from the fraction of dust emission associtaed with the centimeter source relative to the total amount of dust in its surroundings, and the size of the centimeter source. From this correlation, we establish an evolutionary sequence which is consistent with the evolutionary stage expected from maser/outflow/dense gas emission and with the infrared excess.

description: A pervasive challenge in neuroscience is testing whether neuronal connectivity changes over time due to specific causes, such as stimuli, events, or clinical interventions. Recent hardware innovations and falling data storage costs enable longer, more naturalistic neuronal recordings. The implicit opportunity for understanding the self-organised brain calls for new analysis methods that link temporal scales: from the order of milliseconds over which neuronal dynamics evolve, to the order of minutes, days or even years over which experimental observations unfold. This review article demonstrates how hierarchical generative models and Bayesian inference help to characterise neuronal activity across different time scales. Crucially, these methods go beyond describing statistical associations among observations and enable inference about underlying mechanisms. We offer an overview of fundamental concepts in state-space modeling and suggest a taxonomy for these methods. Additionally, we introduce key mathematical principles that underscore a separation of temporal scales, such as the slaving principle, and review Bayesian methods that are being used to test hypotheses about the brain with multi-scale data. We hope that this review will serve as a useful primer for experimental and computational neuroscientists on the state of the art and current directions of travel in the complex systems modelling literature.

Beyond Mean-Field Theory for Attractive Bosons under Transverse Harmonic Confinement

description: We study a dilute gas of attractive bosons confined in a harmonic cylinder, i.e. under cylindric confinement due to a transverse harmonic potential. We introduce a many-body wave function which extends the Bethe ansatz proposed by McGuire (J. Math. Phys. {\bf 5}, 622 (1964)) by including a variational transverse Gaussian shape. We investigate the ground state properties of the system comparing them with the ones of the one-dimensional (1D) attractive Bose gas. We find that the gas becomes ultra 1D as a consequence of the attractive interaction: the transverse width of the Bose gas reduces by increasing the number of particles up to a critical width below which there is the collapse of the cloud. In addition, we derive a simple analytical expression for the simmetry-breaking solitonic density profile of the ground-state, which generalize the one deduced by Calogero and Degasperis (Phys. Rev. A {\bf 11}, 265 (1975)). This bright-soliton analytical solution shows near the collapse small deviations with respect to the 3D mean-field numerical solution. Finally, we show that our variational Gauss-McGuire theory is always more accurate than the McGuire theory. In addition, we prove that for small numbers of particles the Gauss-McGuire theory is more reliable than the mean-field theory described by the 3D Gross-Pitaevskii equation.

An analysis of storm evolution and structure is performed, including precipitation efficiency and storm dynamics. Results show large increases in surface precipitation with increasing resolution regardless of the MP parameterization, especially between 1 km and 250 m grid spacing.

Coronal mass ejections, which are explosions of solar material and energy into space, pose a potential threat to satellite and electrical grid infrastructures, yet little is known about the solar corona. Various questions exist, relating to the origins of these mass ejections as well as the mechanisms involved in coronal heating. The corona and coronal mass ejections are measured by satellite and ground-based coronagraphs, instruments that produce a false eclipse of the Sun in order to separate the extremely faint coronal signature from the bright solar disk. Earth’s atmosphere and the presence of aerosols limit the usefulness of images obtained from ground-based coronagraphs compared to satellite observations. We have developed image processing algorithms to remove aerosols from a new high-speed detector in real time. Two images, a mean and a median image, were first generated from a time series of images containing real aerosols. Then a thresholding algorithm was applied to all of the images within the time series. If the pixel values exceeded the mean and/or median image value, they were replaced with the value in that mean or median image. Both techniques were successful in removing aerosols from imagery. Due to signal-to-noise advantages gained by utilizing the mean image instead of the median image, the mean is the preferred method. Processing ∼1 second of imagery (150 frames per second) required ∼180 seconds on a dual-core 2.33 GHz CPU. Further optimization will promote real-time aerosol removal in solar observation.

description: It is widely believed that magnetic reconnection plays an important role in various eruptive phenomena of space and astrophysical plasmas. The mechanism of anomalous resistivity, however, has been an open and unsolved problem. The chaos-induced resistivity proposed by Yoshida (1998) is one of possible mechanisms for anomalous resistivity. By use of the test particle simulation, the present work studies the chaos-induced resistivity for different configurations of reconnection magnetic fields and its distribution in different chaos regions of reconnection current sheets. The results show that the chaos-induced resistivity can be 6-7 orders of magnitude higher than the classical Spitzer resistivity in the X-type chaos regions and 5 orders of magnitude in the O-type chaos regions. Moreover, in the X-type chaos regions the chaos-induced resistivity of the magnetized case is higher by a factor of 2 to 3 times than that of the unmagnetized case, but in the O-type chaos regions the chaos-induced resistivity of the magnetized case is close to or lower than that of the unmagnetized case. The present work is helpful to the understanding of the dynamics of reconnection current sheets, especially of the generation mechanism of the anomalous resistivity of collisionless reconnection regions.

description: The intent recognition is an essential algorithm of any conversational AI application. It is responsible for the classification of an input message into meaningful classes. In many bot development platforms, we can configure the NLU pipeline. Several intent recognition services are currently available as an API, or we choose from many open-source alternatives. However, there is no comparison of intent recognition services and open-source algorithms. Many factors make the selection of the right approach to the intent recognition challenging in practice. In this paper, we suggest criteria to choose the best intent recognition algorithm for an application. We present a dataset for evaluation. Finally, we compare selected public NLU services with selected open-source algorithms for intent recognition.

description: This case study illustrates an organic bottom-up place-making process, which started with the initiative of a couple of residents who created an invented folktale as a gift to their community. Through the development of a fictional character, these residents intuitively tried to embody the place’s norms and values or, in others words, the DNA of the community. The challenge, however, was how to transform this single initiative into shared meaning-making, borne by the wider local community. Two trends, noted in place-making literature, are of significance for the case. First, the case shows that, in making the place more attractive to live, the focus should be on the intangible attributes— the cultural soul of the place. Secondly, the case illustrates, through the use of the Imagineering Design Methodology, how the wider community has been enabled to become co-producers and co-consumers in the place-making process. Moreover, by actively including disruptive voices, such as those locals who were critical in the enabling interventions, the place-making process evolved. The case, therefore, shows how these interventions led to a participatory effect.
A semantically-enhanced object-oriented case tool for enterprise modeling

description: This thesis is motivated by the desire to build a semantically-enhanced Computer-Aided Software Engineering (CASE) tool that systems analysts would find useful in helping them build object-oriented enterprise models. The tool would incorporate the unique ability to evaluate candidate models against a set of predefined semantic rules. The rules are those of the Object-Oriented Enterprise Modeling (OOEM) method proposed by Wand and Woo (1993). A survey of current CASE Tools, three of which are reviewed in this thesis, consistently reveal an absence of a built-in semantic integrity checking utility built for or around the tools. The tools were indeed very powerful but were only able to detect syntactic violations in a model. This thesis takes the view that it is possible, and indeed important for a CASE tool to assist users in building and checking for semantically consistent object-oriented enterprise models. The chapters in this thesis describe a range of activity - from theory strengthening to empirical testing - all with the singular objective of discovering if analysts would in fact find such a tool useful. The empirical study revealed that analysts do welcome a CASE tool with semantic checking capability. However, much remains to be done to provide a user interface that would, among other things, assist analysts in structuring their thoughts and ideas on the computer. Work also remains to be done on improving the diagnostic utility's user interface.

Road weather

Each year, adverse weather along roadways results in over 7,000 fatalities, 673,000 injuries, nearly $9.5 billion in congestion delays, and costs shipping companies $3.5 billion. Currently, decision support systems recommend road surface treatments for snow removal operations by incorporating output from pavement temperature models. However, current pavement temperature models issue point forecasts that fail to describe the conditions between the points. A forecast from a gridded pavement model is a possible solution to this problem. To produce this forecast, the sensitivity of the pavement temperature when stratified by different materials (i.e., concrete and asphalt) and their thicknesses must be assessed. This analysis used eight Road Weather Information System (RWIS) stations in the greater Denver, Colorado metropolitan area and four RWIS sites at Denver International Airport. Uniform radiation was assumed using a cross-referencing method between five-minute daily weather observations and satellite-surface composite maps. Sixteen total case studies were selected for day and night with diverse weather conditions. Concrete roads generally averaged 3.2° C warmer than asphalt roads and therefore will have to be modeled separately. Elevated (e.g., overpass) and non-elevated surfaces were also compared, and elevated roads tended to be 3.3° C cooler than non-elevated; therefore, a condition protocol for the elevated site will subtract 3° C from the standard forecast. This work lays the foundation for additional analyses with a more robust data set to confirm initial results observed from these data, the results of which may be used to develop and tune gridded pavement model forecasts.

Our surface transportation infrastructure and the public who use it are becoming increasingly vulnerable to severe weather conditions. Statistics show that 24% of all United States highway crashes are weather-related and each year, nearly 7,400 people are killed and over 673,000 people are injured in these crashes. The National Highway Traffic Safety Administration (NHTSA) estimates the average cost per crash in 2000 to be $14,100 (Pisano et al. 2008). Weather-related crashes are defined by the Federal Highway Administration (FHWA) Road Weather Management program as those that occur in the presence of rain, sleet, snow, fog, wet pavement, snowy/slushy pavement, and/or icy pavement. Current methods to mitigate the impacts of these severe conditions include advisory information disseminated to travelers via local media, control options such as closing roads, and treatment operations that include snow removal. Decision support systems geared for a diverse group of end-users are becoming more widely implemented to combat the forces of nature. These systems can integrate atmospheric variables such as numerical weather prediction models and road pavement temperature with the resources available to a given municipality to produce a recommended course of action to ensure safety and efficiency. In addition, a connected system of vehicles that monitor road conditions and communicate with one another, in order to provide alerts of hazardous conditions ahead, promises to be a vital component of these systems. Decision support systems and connected vehicle technology represent the newest emerging technologies that will impact the future of intelligent transportation systems.
Effects of the $α$-cluster structure and the intrinsic momentum component of nuclei on the longitudinal asymmetry in relativistic heavy-ion collisions

description: The longitudinal asymmetry in relativistic heavy ion collisions arises from the fluctuation in the number of nucleons involved. This asymmetry causes a rapidity shift in the center of mass of the participating zone. Both the rapidity shift and the longitudinal asymmetry have been found to be significant at the top CERN Large Hadron Collider (LHC) energy for collisions of identical nuclei, and the longitudinal asymmetry is important for reconstructing the colliding vertex and correcting the rapidity shift. However, much discussion of the longitudinal asymmetry has treated the initial condition as a nonzero momentum contributed only by the number of participants, i.e., the asymmetry depends only on the number of participating nucleons. So we naturally raise a physical problem, can other initial conditions, such as two typical initial conditions for nuclei, geometric configuration, and momentum distribution, provide effects on the longitudinal asymmetry? Therefore, in this work we consider other effects on the longitudinal asymmetry other than the fluctuation in the number of participants, e.g., the α clustering structure as well as the intrinsic momentum distribution in the target and projectile nuclei for the collisions in the framework of a multiphase transport (AMPT) model. By introducing systems with different α-clustering structure and intrinsic momentum distribution, we calculated the ratio of the rapidity distributions of different systems and extracted expansion coefficients to analyze the difference contributed by these factors. ...

description: With the use of thermodynamics and general equilibrium conditions only, we study the entropy of a fluid in the vicinity of the critical point of the liquid-vapor phase transition. By assuming a general form for the coexistence curve in the vicinity of the critical point, we show that the functional dependence of the entropy as a function of energy and particle densities necessarily obeys the scaling form hypothesized by Widom. Our analysis allows for a discussion on the properties of the corresponding scaling function, with the interesting prediction that the critical isotherm has the same functional dependence, between the energy and particles densities, as the coexistence curve. In addition to the derivation of the expected equalities of the critical exponents, the conditions that lead to scaling also imply that while the specific heat at constant volume can diverge at the critical point, the isothermal compressibility must do so.

description: C$_3$N$_4$ is a recently discovered phase of carbon nitrides with the tetragonal crystal structure [D.Laniel $\textit{et al.}$, Adv. Mater. 2023, 2308030] that is stable at ambient conditions. C$_3$N$_4$ is a semiconductor exhibiting flat-band anomalies in the valence band, suggesting the emergence of many-body instabilities upon hole doping. Here, using state-of-the-art first-principles calculations we show that hole-doped C$_3$N$_4$ reveals strong electron-phonon coupling, leading to the formation of a gapped superconducting state. The phase transition temperatures turn out to be strongly dependent on the hole concentration. We propose that holes could be injected into C$_3$N$_4$ via boron doping which induces, according to our results, a rigid shift of the Fermi energy without significant modification of the electronic structure. Based on the electron-phonon coupling and Coulomb pseudopotential calculated from first principles, we conclude that the boron concentration of 6 atoms per nm$^3$ would be required to reach the critical temperature of $\sim$36 K at ambient pressure.

description: In order to characterize giant exoplanets and better understand their origin, knowledge of how the planet's composition depends on its mass and stellar environment is required. In this work, we simulate the thermal evolution of gaseous planets and explore how various common model assumptions such as different equations of state, opacities, and heavy-element distributions affect the inferred radius and metallicity. We examine how the theoretical uncertainties translate into uncertainties in the inferred planetary radius and bulk metallicity. While we confirm the mass-metallicity trend previously reported in the literature, this correlation disappears when removing a 20 $M_{\oplus}$ heavy-element core from all the planets. We also show that using an updated hydrogen-helium equation of state leads to more compact planets. As a result, we present six planets that should be classified as inflated warm Jupiters. We next demonstrate that including the opacity-enhancement due to metal-rich envelopes of irradiated planets changes the planetary radius significantly, which can have large effects on the inferred metallicity. Even though there are other model assumptions that have not been considered in this work, we could show that the calculated theoretical uncertainties can already be comparable or even larger than the observational ones. Therefore, theoretical uncertainties are likely to be even larger. We therefore conclude that progress in theoretical models of giant planets is essential in order to take full advantage of current and future exoplanetary data.
