description: We theoretically study the superfluid phase of a strongly correlated $^{173}$Yb Fermi gas near its orbital Feshbach resonance, by developing a quantitative pair-fluctuation theory within a two-band model. We examine the density excitation spectrum of the system and determine a stability phase diagram. We find that the $^{173}$Yb Fermi gas is intrinsically metastable and has a peculiar equation of state, due to the small but positive singlet scattering length. The massive Leggett mode, arising from the fluctuation of the relative phase of two order parameters, is severely damped. We discuss the parameter space where an undamped Leggett mode may exist.

description: We extend the well established link between structural change and estimated persistence from GARCH to stochastic volatility (SV) models. Whenever structural changes in some model parameters increase the empirical autocorrelations of the squares of the underlying time series, the persistence in volatility implied by the estimated model parameters follows suit. This explains why stochastic volatility often appears to be more persistent when estimated from a larger sample as then the likelihood increases that there might have been some structural change in between.

description: We consider the dynamical atom-surface Casimir-Polder force in the non-equilibrium configuration of an atom near a perfectly conducting wall, initially prepared in an excited state with the field in its vacuum state. We evaluate the time-dependent Casimir-Polder force on the atom, and find that it shows an oscillatory behavior from attractive to repulsive both in time and in space. We also investigate the asymptotic behavior in time of the dynamical force and of related local field quantities, showing that the static value of the force, as obtained by a time-independent approach, is recovered for times much larger than the timescale of the atomic self-dressing, but smaller than the atomic decay time. We then discuss the evolution of global quantities such as atomic and field energies, and their asymptotic behavior. We also compare our results for the dynamical force on the excited atom with analogous results recently obtained for an initially bare ground-state atom. We show that new relevant features are obtained in the case of an initially excited atom, for example much larger values of the dynamical force with respect to the static one, allowing for an easier way to single-out and observe the dynamical Casimir-Polder effect.

description: This paper presents a Hayashi-Yoshida type estimator for the covariation matrix of continuous Itˆo semimartingales observed with noise. The coordinates of the multivariate process are assumed to be observed at highly frequent nonsynchronous points. The estimator of the covariation matrix is designed via a certain combination of the local averages and the Hayashi-Yoshida estimator. Our method does not require any synchronization of the observation scheme (as e.g. previous tick method or refreshing time method) and it is robust to some dependence structure of the noise process. We show the associated central limit theorem for the proposed estimator and provide a feasible asymptotic result. Our proofs are based on a blocking technique and a stable convergence theorem for semimartingales. Finally, we show simulation results for the proposed estimator to illustrate its finite sample properties.

description: Qatar-1b is a close-orbiting hot Jupiter ($R_p\simeq 1.18$ $R_J$, $M_p\simeq 1.33$ $M_J$) around a metal-rich K-dwarf, with orbital separation and period of 0.023 AU and 1.42 days. We have observed the secondary eclipse of this exoplanet in the Ks band with the objective of deriving a brightness temperature for the planet and providing further constraints to the orbital configuration of the system. We obtained near-infrared photometric data from the ground by using the OMEGA2000 instrument at the 3.5 m telescope at Calar Alto (Spain) in staring mode, with the telescope defocused. We have used principal component analysis (PCA) to identify correlated systematic trends in the data. A Markov chain Monte Carlo analysis was performed to model the correlated systematics and fit for the secondary eclipse of Qatar-1b using a previously developed occultation model. We adopted the prayer bead method to assess the effect of red noise on the derived parameters. We measured a secondary eclipse depth of $0.196\%^{+0.071\%}_{-0.051\%}$, which indicates a brightness temperature in the Ks band for the planet of $1885^{+212}_{-168}$ K. We also measured a small deviation in the central phase of the secondary eclipse of $-0.0079^{+0.0162}_{-0.0043}$, which leads to a value for $e\cosω$ of $-0.0123^{+0.0252}_{-0.0067}$. However, this last result needs to be confirmed with more data.

Iterative quantum-state transfer along a chain of nuclear spin qubits

description: Transferring quantum information between two qubits is a basic requirement for many applications in quantum communication and quantum-information processing. In the iterative quantum-state transfer proposed by Burgarth et al. [Phys. Rev. A 75, 062327 (2007)], this is achieved by a static spin chain and a sequence of gate operations applied only to the receiving end of the chain. The only requirement on the spin chain is that it transfers a finite part of the input amplitude to the end of the chain, where the gate operations accumulate the information. For an appropriate sequence of evolutions and gate operations, the fidelity of the transfer can asymptotically approach unity. We demonstrate the principle of operation of this transfer scheme by implementing it in a nuclear magnetic resonance quantum-information processor.

description: In this paper we are concerned with non-parametric inference on the volatility of volatility process r2 in stochastic volatility models. We construct an estimator for its integrated version R t 0 2 s ds in a high frequency setting which is based on increments of spot volatility estimators, and we are able to prove both feasible and infeasible central limit theorems at the optimal rate n-1/4. Such CLTs can be widely used in practice, as they are the key to essentially all tools in model validation for stochastic volatility models. As an illustration we apply our results to goodness-of- fit testing, providing the first consistent test for a certain parametric form of the volatility of volatility.

description: An eutectic AlCl$_3$/KCl molten salt method in a horizontal configuration was employed to grow millimeter-sized and composition homogeneous CuFeSe$_2$ single crystals due to the continuous growth process in a temperature gradient induced solution convection. The typical as-grown CuFeSe$_2$ single crystals in cubic forms are nearly 1.6$\times$1.2$\times$1.0 mm3 in size. The chemical composition and homogeneity of the crystals was examined by both inductively coupled plasma atomic emission spectroscopy and energy dispersive spectrometer with Cu:Fe:Se = 0.96:1.00:1.99 consistent with the stoichiometric composition of CuFeSe$_2$. The magnetic measurements suggest a ferrimagnetic or weak ferromagnetic transition below T$_C$ = 146 K and the resistivity reveals a semiconducting behavior and an abrupt increase below T$_C$.

description: We introduce an intermediate quantum computing model built from translation-invariant Ising-interacting spins. Despite being non-universal, the model cannot be classically efficiently simulated unless the polynomial hierarchy collapses. Equipped with the intrinsic single-instance-hardness property, a single fixed unitary evolution in our model is sufficient to produce classically intractable results, compared to several other models that rely on implementation of an ensemble of different unitaries (instances). We propose a feasible experimental scheme to implement our Hamiltonian model using cold atoms trapped in a square optical lattice. We formulate a procedure to certify the correct functioning of this quantum machine. The certification requires only a polynomial number of local measurements assuming measurement imperfections are sufficiently small.

Year: 1998
Subjects: subject: 004

description: In this paper, we extend the set of library components which are usually considered in architectural synthesis by components with built-in chaining. For such components, the result of some internally computed arithmetic function is made available as an argument to some other function through a local connection. These components can be used to implement chaining in a data-path in a single component. Components with built-in chaining are combinatorial circuits. They correspond to ``complex gates in logic synthesis. If compared to implementations with several components, components with built-in chaining usually provide a denser layout, reduced power consumption, and a shorter delay time. Multiplier/accumulators are the most prominent example of such components. Such components require new approaches for library mapping in architectural synthesis. In this paper, we describe an IP-based approach taken in our OSCAR synthesis system.

description: Marine stratocumulus cloud decks are regarded as the reflectors of the climate system, returning back to space a significant part of the income solar radiation, thus cooling the atmosphere. Such clouds can exist in two stable modes, open and closed cells, for a wide range of environmental conditions. This emergent behavior of the system, and its sensitivity to aerosol and environmental properties, is captured by a set of nonlinear equations. Here, using linear stability analysis, we express the transition from steady to a limit-cycle state analytically, showing how it depends on the model parameters. We show that the control of the droplet concentration (N) the environmental carrying-capacity (H0) and the cloud recovery parameter (tau) can be linked by a single nondimensional parameter mu=N/(alfa*tau*H0), suggesting that for deeper clouds the transition from open (oscillating) to closed (stable fixed point) cells will occur for higher droplet concentration (i.e. higher aerosol loading). The analytical calculations of the possible states, and how they are affected by changes in aerosol and the environmental variables, provide an enhanced understanding of the complex interactions of clouds and rain.

description: This paper examines the effectiveness of learner-centered teaching strategies in the context of the Teaching4Learning@Unipd initiative at the University of Padua. The initiative, established in 2016, aimed to promote active teaching and improve classroom and study course instruction. The study analyzes the impact of the project on student evaluation, motivation, and preparedness through state-of-the-art difference-in-differences models. The findings suggest that while innovative teaching did not negatively affect students' opinions compared to traditional courses, there is only modest evidence of improvement in student outcomes. The paper discusses the mechanisms underlying these effects and explores potential avenues for future research. This study represents the first comprehensive investigation of its kind in Italy, utilizing rigorous econometric techniques and a wealth of data, and serves as a crucial foundation for future studies on the link between teacher training and student learning.

description: The set $GU_f$ of possible effective elastic tensors of composites built from two materials with elasticity tensors $\BC_1>0$ and $\BC_2=0$ comprising the set $U=\{\BC_1,\BC_2\}$ and mixed in proportions $f$ and $1-f$ is partly characterized. The material with tensor $\BC_2=0$ corresponds to a material which is void. (For technical reasons $\BC_2$ is actually taken to be nonzero and we take the limit $\BC_2\to 0$). Specifically, recalling that $GU_f$ is completely characterized through minimums of sums of energies, involving a set of applied strains, and complementary energies, involving a set of applied stresses, we provide descriptions of microgeometries that in appropriate limits achieve the minimums in many cases. In these cases the calculation of the minimum is reduced to a finite dimensional minimization problem that can be done numerically. Each microgeometry consists of a union of walls in appropriate directions, where the material in the wall is an appropriate $p$-mode material, that is easily compliant to $p\leq 5$ independent applied strains, yet supports any stress in the orthogonal space. Thus the material can easily slip in certain directions along the walls. The region outside the walls contains "complementary Avellaneda material" which is a hierarchical laminate which minimizes the sum of complementary energies.

description: We determine the topological phase diagram of BiTl(S$_{1-δ}$Se$_δ$)$_2$ as a function of doping and temperature from first-principles calculations. Due to electron\textendash phonon interaction, the bands are renormalized at finite temperature, allowing for a transition between the trivial ($Z_2=0$) and non-trivial ($Z_2=1$) topological phase. We find two distinct regions of the phase diagram with non-trivial topology. In BiTlS$_2$, the phonons promote the crystal to the topological phase at high temperature, while in BiTlSe$_2$, the topological phase exists only at low temperature. This behaviour is explained by the symmetry of the phonon coupling potential, whereby the even phonon modes (whose potential is even under inversion) promote the topological phase and the odd phonon modes promote the trivial phase.

description: In this paper, we consider a charged massive fermionic quantum field in the idealized cosmic string spacetime and in the presence of a magnetic field confined in a cylindrical tube of finite radius. Three distinct configurations for the magnetic fields are taken into account: (i) a cylindrical shell of radius $a$, (ii) a magnetic field proportional to $1/r$ and (iii) a constant magnetic field. In these three cases, the axis of the infinitely long tube of radius $a$ coincides with the cosmic string. Our main objectives in this paper are to analyze the fermionic condensat (FC) e and the vacuum expectation value (VEV) of the fermionic energy-momentum tensor. In order to do that, we explicitly construct the complete set of normalized wave-functions for each configuration of magnetic field. We show that in the region outside the tube, the FC and the VEV of the energy-momentum tensor are decomposed into two parts: the first ones correspond to the zero-thickness magnetic flux contributions, and the seconds are induced by the non-trivial structure of the magnetic field, named core-induced contributions. The latter present specific forms depending on the magnetic field configuration considered. We also show that the VEV of the energy-momentum tensor is diagonal, obeys the conservation condition and its trace is expressed in terms of the fermionic condensate. The zero-thickness contributions to the FC and VEV of the energy-momentum tensor, depend only on the fractional part of the ration of the magnetic flux inside the tube by the quantum one. As to the core-induced contributions they depend on the total magnetic flux inside the tube, and consequently, in general, are not a periodic function of the magnetic flux.

Although simple, the system is exceedingly flexible and allows for household and parcel heterogeneity. We derive an empirical model directly from the structural equations and contrast this using a simulated landscape with the econometric specification most often found in the literature. We then show how the model can be used to project land-use change into the future and for policy simulation. Finally, we use the model to examine the impact of common land conservation policies in Europe.

Optimized power grid operations for negative pricing using  collective intelligence
Creators: name: Renganathan, Vasantharajan
Publisher: name: Zenodo
Year: 2024

description: Electricity pricing in the market has been going negative in recent days due to lower demand or Net Demand Variability (NDV) in the instances of surplus supply due to variable additional sources in the market. The WG (Working Group) analysis reflects the same as fossil fuels like coal/gas are relieved by renewable energy like wind/solar. Negative pricing (NP) is a market-based methodology to administrate excess supply to electric grid as this excess supply imbalances the supply/demand curve.NP is predominant in western countries like Europe, Americas & Australia. But it is getting more common these days in Indian grid. Mere cutting off the source may help the administration manage the situation, but NP, if used with a Collective Intelligence (CI) can help both suppliers, users & the overall economy of the nation. Here CI refers to the data interaction among suppliers, users & power grid administrators with the aid of AI. CI here helps industries consuming power to get prepared in advance to use the available power or subsidized power to keep up the demand and avoid the grid operation in NP regime. The way of dealing with NP & utilizing a catastrophe as an opportunity is discussed in this paper.

CI has been implemented in many countries among various electricity suppliers, but not among the various users of industry. Observed energy savings ranging from 10~30% ($220~$1.7 billion) has been experienced by various countries. If CI is extended among these industrial stakeholders with effective planning and implementation mentioned in this article, the % savings could even exceed above 30% in energy and $1.7 billion.

Year: 2019

description: The aim of this study is therefore to describe the relationship between development and personal related factors and business related factors on MSEs in Gullele sub city of Addis Ababa. In this study, descriptive research designs were used. Stratified random sampling was used to select proportional number of samples from the study area. Both primary and secondary source of data were used. To obtain the Primary data were collected from a sample of 82 randomly selected MSEs engaged in industry and service sector, through structured questionnaire by using stratified random sampling techniques. Data were analyzed using descriptive and inferential statistics. Specifically, analysis of variance was carried out to examine the variation in the development of enterprises related to the variation in each of the independent variables of the study. In terms of the result, descriptive statistics shows higher development for enterprises owned by individuals with better education level, prior management experience, marketing skill and planning and record keeping. However, results from analysis of variance show no significance variation on the development of MSEs in relation to the variations to each of the independent variables considered. But based on descriptive statistics result, MSEs should start using plan to their business activities and adopt a formal record keeping and financial control system in their internal practice. And also stake holders of the sector should work on preparing training programs on management issues and creating experience sharing opportunities especially to those enter into the sector without any management experience.

description: The set $GU_f$ of possible effective elastic tensors of composites built from two materials with positive definite elasticity tensors $\BC_1$ and $\BC_2=\Gd\BC_0$ comprising the set $U=\{\BC_1,\Gd\BC_0\}$ and mixed in proportions $f$ and $1-f$ is partly characterized in the limit $\Gd\to\infty$. The material with tensor $\BC_2$ corresponds to a material which (for technical reasons) is almost rigid in the limit $\Gd\to \infty$. The paper, and the underlying microgeometries, have many aspects in common with the companion paper "On the possible effective elasticity tensors of 2-dimensional printed materials". The chief difference is that one has a different algebraic problem to solve: determining the subspaces of stress fields for which the thin walled structures can be rigid, rather than determining, as in the companion paper, the subspaces of strain fields for which the thin walled structure is compliant. Recalling that $GU_f$ is completely characterized through minimums of sums of energies, involving a set of applied strains, and complementary energies, involving a set of applied stresses, we provide descriptions of microgeometries that in appropriate limits achieve the minimums in many cases. In these cases the calculation of the minimum is reduced to a finite dimensional minimization problem that can be done numerically. Each microgeometry consists of a union of walls in appropriate directions, where the material in the wall is an appropriate $p$-mode material, that is almost rigid to $6-p\leq 5$ independent applied stresses, yet is compliant to any strain in the orthogonal space. Thus the walls, by themselves, can support stress with almost no deformation. The region outside the walls contains "Avellaneda material" that is a hierarchical laminate which minimizes an appropriate sum of elastic energies.

description: The present paper is concerned with Lipschitz properties of convex mappings. One considers the general context of mappings defined on an open convex subset $Ω$ of a locally convex space $X$ and taking values in a locally convex space $Y$ ordered by a normal cone. One proves also equi-Lipschitz properties for pointwise bounded families of continuous convex mappings, provided the source space $X$ is barrelled. Some results on Lipschitz properties of continuous convex functions defined on metrizable topological vector spaces are included as well. The paper has a methodological character - its aim is to show that some geometric properties (monotonicity of the slope, the normality of the seminorms) allow to extend the proofs from the scalar case to the vector one. In this way the proofs become more transparent and natural.

An Assessment Of Tourist Destination Brand Image Perception: The Case Of Addis Ababa City
Creators: name: Gizachew, Kebede
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The main purpose of this research is to assess tourists' perception of the brand image of the Addis Ababa City. Data for the sample was collected from 393 tourists who visited Addis Ababa City between 11 April 2017 and 15 May 2017. Descriptive statistics, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and regression analysis were conducted to test the hypotheses. The results show that the cognitive destination image is a multidimensional construct. Also it is confirmed that both cognitive and affective destination brand image perceptions significantly contributes for conative destination brand image perception, i.e. the cognitive and the affective components of destination image can be used as a predictor of tourists' behavioral intentions toward destinations, such as intention to revisit and recommend for others. In terms of magnitude the affective destination brand image perception contributes more for the conative brand image perception than the cognitive brand image perception does. This study found out that both the cognitive and affective destination brand images significantly and positively contribute to the conative destination brand image. The results of the regression analysis indicated that the cognitive destination brand image contributes significantly (B=0.31, P<0.01) to the conative destination image. The affective destination brand image also contributes significantly (B=0.34, P<0.01) to the conative image. Based on the findings of the research it recommended that there should be a well-coordinated effort in building the brand image of the Addis Ababa City and the competitiveness of the city as a destination should be enhanced through marketing both the cognitive and affective destination image aspects. Also, there should be government-private-professional partnership in order to build the institutional capacity of the tourism sector of the Addis Ababa City

description: Density perturbations in cosmology, i.e. spherically symmetric adiabatic perturbations of a Friedmann-Lemaître-Robertson-Walker (FLRW) spacetime, are locally exactly equivalent to a different FLRW solution, as long as their wavelength is much larger than the sound horizon of all fluid components. This fact is known as the "separate universe" paradigm. However, no such relation is known for anisotropic adiabatic perturbations, which correspond to an FLRW spacetime with large-scale tidal fields. Here, we provide a closed, fully relativistic set of evolutionary equations for the nonlinear evolution of such modes, based on the conformal Fermi (CFC) frame. We show explicitly that the tidal effects are encoded by the Weyl tensor, and are hence entirely different from an anisotropic Bianchi I spacetime, where the anisotropy is sourced by the Ricci tensor. In order to close the system, certain higher derivative terms have to be dropped. We show that this approximation is equivalent to the local tidal approximation of Hui and Bertschinger (1995). We also show that this very simple set of equations matches the exact evolution of the density field at second order, but fails at third and higher order. This provides a useful, easy-to-use framework for computing the fully relativistic growth of structure at second order.

title: Ανάπτυξη τρισδιάστατου παιχνιδιού αγώνα ταχύτητας με αυτονομία αντιπάλου για κινητές συσκευές

description: Στόχος της παρούσας διπλωματικής είναι η υλοποίηση ενός τρισδιάστατου ηλεκτρονικού παιχνιδιού το οποίο θα απευθύνεται σε κινητές συσκευές αφής όπως smartphones και tablets. Το  παιχνίδι καθαυτό είναι είδος αγώνων ταχύτητας όπου στόχος του χρήστη είναι να τερματίσει στην πρώτη θέση για να θεωρείτε επιτυχής η προσπάθεια του είτε αντίπαλος του είναι ένα άλλο αυτόνομο όχημα είτε είναι ο χρόνος. Για το σκοπό αυτό δημιουργήσαμε δύο είδη παιχνιδιού. Το πρώτο είδος ονομάζεται Arcade όπου ο παίχτης πρέπει να τερματίσει πρώτος σε μία από τις τρεις διαφορετικές πίστες που έχουμε δημιουργήσει χρησιμοποιώντας τόσο ο ίδιος όσο και ο αντίπαλος τις διάφορες δυνάμεις που υπάρχουν στην πίστα. Ο αντίπαλος του παίχτη ελέγχεται από τον υπολογιστή ο οποίος ανάλογα με τις καταστάσεις κρίνει τι θα πράξει. Το δεύτερο είδος ονομάζεται Timetrial  όπου ο παίχτης  πρέπει να καταφέρει να ολοκληρώσει την διαδρομή της πίστας υπό την πίεση του χρόνου και την ανανέωση του από κάθε σημείο ελέγχου. Παράλληλα υλοποιήθηκε ένα τριπλό σύστημα δυσκολίας του αντιπάλου και επιλογή χειριστηρίων για κινητών συσκευών αφής. Τέλος έχει δημιουργηθεί ένα διαδραστικό HUD (Heads up display) το οποίο μεταβάλλεται αναλόγως με το τι συμβαίνει την ώρα του παιχνιδιού. Το παιχνίδι έχει σχεδιαστεί και υλοποιηθεί χρησιμοποιώντας τεχνικές και τεχνολογίες όπως η οθόνη αφής και το επιταχυνσιόμετρο που χρησιμοποιούνται για την κατασκευή παιχνιδιών που απευθύνονται σε κινητές συσκευές αφής.
description: The aim of this thesis is the implementation of a 3D game which will be aimed at mobile touch devices such as smartphones and tablets. The game itself is a type of speed racing where the goal of the user is to finish in first place to be considered successful, whether his opponent is another autonomous vehicle or time. For this purpose, we created two types of game. The first type is called Arcade where the player must finish first on one of the three different tracks we have created. Both the player and the opponent can use the different powers that are present on the track. The player's opponent is controlled by the computer which, depending on the situation, decides what to do. The second type is called Timetrial where the player must manage to complete the course of the track under the pressure of time which is renewed from each checkpoint. A triple opponent difficulty system and a choice of controls for mobile touch devices were also implemented. Finally, an interactive HUD (Heads up display) has been created which changes according to what is happening during the game. The game is designed and implemented using techniques and technologies such as touch screen and accelerometer that are used to make games aimed at mobile touch devices.

description: Nederlanders besteden steeds minder tijd aan het lezen van langere teksten. Vooral de daling van de leestijd en het gebrek aan leesplezier bij jongeren leiden tot zorgen. De behoefte aan het lezen, delen en luisteren van verhalen blijft, maar verschuift naar andere plaatsen en andere kanalen. Tegelijkertijd zijn er nieuwe initiatieven in boekhandel, bibliotheek en uitgeverij. Literaire podia en festivals bloeien op, de interesse voor het zelf schrijven van proza en poëzie groeit en leesclubs en online platforms weten met ‘sociaal lezen’ communities aan zich te binden.

Galactic and Extragalactic Analysis of the Astrophysical Muon Neutrino Flux with 12.3 years of IceCube Track Data

description: The Ice Cube Neutrino Observatory has been measuring an isotropic astrophysical neutrino flux in multiple detection channels for almost a decade. Galactic diffuse emission, which arises from the interactions between cosmic rays and the interstellar medium, is an expected signal in IceCube. The superposition of an extragalactic flux and a galactic flux results in directional structure and variations in the spectrum. In this work, we use 12.3 years of high-purity muon-neutrino induced muon track data to perform a dedicated search for this galactic emission, combined with a spectral measurement of the isotropic astrophysical neutrino flux. To distinguish a galactic component from the dominant atmospheric and isotropic astrophysical components, the precise directional information available for muon tracks is fully utilized in a three-dimensional forward folding likelihood fit. We test a state-of-the-art model prediction of galactic diffuse emission based on recent cosmic ray data (CRINGE). We fit this prediction as a template scaled by a factor $Ψ_{\mathrm{CRINGE}}$, and find $2.9\pm 1.1 \times Ψ_{\mathrm{CRINGE}}$ with a significance of $2.7σ$ in an energy range between 400 GeV and 60 TeV in the Northern Sky.

13-Moment System with Global Hyperbolicity for Quantum Gas

description: We point out that the quantum Grad's 13-moment system [R. Yano, Physica A: Statistical Mechanics and its Applications, 416:231-241, 2014] is lack of global hyperbolicity, and even worse, the thermodynamic equilibrium is not an interior point of the hyperbolicity region of the system. To remedy this problem, by fully considering Grad's expansion, we split the expansion into the equilibrium part and the non-equilibrium part, and propose a regularization for the system with the help of the new theory developed in [Z. Cai et al., SIAM J. Appl. Math., 75(5):2001-2023, 2015, Y. Fan, J. Stat. Phys., 161(4), 2015]. This provides us a new model which is hyperbolic for all admissible thermodynamic states, and meanwhile preserves the approximate accuracy of the original system. It should be noted that this procedure is not a trivial application of the theory in [Z. Cai et al., SIAM J. Appl. Math., 75(5):2001-2023, 2015, Y. Fan, J. Stat. Phys., 161(4), 2015].
