description: This dissertation investigates a mechanism for confidentiality preservation in first-order logic databases. The logical basis is given by the inference control framework of Controlled Query Evaluation (CQE). Beyond traditional access control, CQE incorporates an explicit representation of a user's knowledge and his ability to reason with information; it hence prevents disclosure of confidential information that would occur due to inferences drawn by the user. This thesis pioneers a new approach in the CQE context: An unprotected database instance is transformed into an inference-proof instance that does not reveal confidential information; the inference-proof instance formally guarantees confidentiality with respect to a representation of user knowledge and a specification of confidential information. Hence, inference-proofness ensures that all user queries can truthfully be answered by the database; no sequence of responses enables the user to infer confidential information. Due to this concept, query evaluation on the inference-proof instance does not incur any performance degradation. As a second design goal, the availability requirement to maintain as much as possible of the correct information in the input database is accounted for by minimization of a distortion distance. The transformation modifies the input instance to provide the user with a consistent view of the data. The algorithm relies on query evaluation on the database to efficiently identify those tuples that are to be added or deleted. Due to undecidability of the general first-order case, appropriate fragments are analyzed. The formalization is started with universal formulas (for which a restriction to allowed formulas is chosen); it moves on to existential formulas and then finishes up with tuple-generating dependencies accompanied by existential and denial formulas. The due proofs of refutation soundness engage a version of Herbrand's theorem with semantic trees. An effort was made to present a broad background of related work. Last but not least, exposition and analysis of a prototypical implementation prove practicality of the approach.

description: Could new physics first manifest itself in Higgs self-coupling measurements? In other words, how large could deviations in the Higgs self-coupling be, if other Higgs and electroweak measurements are compatible with Standard Model predictions? Using theoretical arguments supported by concrete models we derive a bound on the ratio of self-coupling to single-Higgs coupling deviations in ultraviolet completions of the Standard Model where parameters are not fine-tuned. Broadly speaking, a one-loop hierarchy is allowed. We thus stress that self-coupling measurements at the LHC and future colliders probe uncharted parameter space, presenting discovery potential even in the absence of emerging hints in single-Higgs coupling measurements. For instance, if other observables show less than two-sigma deviations by the end of the LHC programme, the Higgs self-coupling deviations could still exceed 200% in the models discussed, without introducing fine-tuning of ultraviolet parameters.

description: A análise do fluxo populacional em ambientes de risco utilizando-se autômatos celula-res (ACs) vem sendo um tema recorrente em trabalhos nosúltimos anos devidoà influência que podem ter sobre os projetos de construção predial e na implementação de medidas de emergência mais eficazes [2]. Os ACs são modelos matemático-computacionais compos-tos por um reticulado de dimensão d, dividido em células x ij de mesmo tamanho, cada uma apresentando um estado k e com uma geometria definida. Os estados das células são regidos por uma regra de transição, sendo que quando a aplicamos por T passos de tempo obtemos a evolução espaço-temporal do modelo. Há uma vasta gama de estudos envolvendo a dinâmica de pedestres, porém em sua maioria os modelos desenvolvidos são compostos por um reticulado 2D com A i saídas em que as células x ij recebem valores específicos-distância Euclidiana de uma célula x ij até uma saída A i. O objetivo de cada pedestreé sair do reticulado através de uma rota otimizada em uma das saídas A i. O tempo final T de evacuaçãoé calculado quando todos os pedestres evacuam do reticulado. Para o nosso modelo foram utilizadas características básicas dos modelos de [4] e [1], com a adição de um mecanismo para impedir movimentos cruzados em forma perpendicular (se dois ou mais pedestres tentam cruzar duas células numângulo de 90 o dentro da vizinhança de Moore, o movimentoé impedido). Este mecanismo físico primordial, não foi considerado nos modelos precursores, sendo este um mecanismo físico que sempre deve ser levado em consideração num modelo de evacuação de pedestres. Seguindo os trabalhos precursores, a movimentação dos pedestresé regida colocando N pedestres em um reticu-lado bidimensional com as células x ij cujos valores são menores próximos as saídas A i e aumentamà medida que distanciam de A i. O objetivo de cada indivíduoé movimentar-se para a célula de menor valor em sua vizinhança de Moore (movimentos determinísticos) até que este consiga sair do ambiente sem lesão. Conflitos entre pedestres que tem intenção de movimento para a mesma célula x ij ou quando duas células x ij = x kl de menor valor são encontradas na vizinhança de Moore, são resolvidos conforme modelo-físico estocástico proposto em [4].

description: We report a search for photon-photon elastic scattering in vacuum in the X-ray region at an energy in the center of mass system of ω_{cms} =6.5 keV for which the QED cross section is σ_{QED} =2.5 \times 10^{-47} m^2. An X-ray beam provided by the SACLA X-ray Free Electron Laser is split and the two beamlets are made to collide at right angle, with a total integrated luminosity of (1.24 \pm 0.08) \times 10^{28} m^{-2}. No signal X rays from the elastic scattering that satisfy the correlation between energy and scattering angle were detected. We obtain a 95% C.L. upper limit for the scattering cross section of 1.9 \times 10^{-27} m^2 at ω_{cms}=6.5 keV. The upper limit is the lowest upper limit obtained so far by keV experiments.

description: Classical models of spin systems traditionally retain only the dipole moments, but a quantum spin state will frequently have additional structure. Spins of magnitude $S$ have $N=2S+1$ levels. Alternatively, the spin state is fully characterized by a set of $N^{2}-1$ local physical observables, which we interpret as generalized spin components. For example, a spin with $S=1$ has three dipole components and five quadrupole components. These components evolve under a generalization of the classical Landau-Lifshitz dynamics, which can be extended with noise and damping terms. In this paper, we reformulate the dynamical equations of motion as a Langevin dynamics of SU($N$) coherent states in the Schrödinger picture. This viewpoint is especially useful as the basis for an efficient numerical method to sample spin configurations in thermal equilibrium and to simulate the relaxation and driven motion of topological solitons. To illustrate the approach, we simulate a non-equilibrium relaxation process that creates CP$^{2}$ Skyrmions, which are topological defects with both dipole and quadrupole character.

description: We extend results known for the randomized Gauss-Seidel and the Gauss-Southwell methods for the case of a Hermitian and positive definite matrix to certain classes of non-Hermitian matrices. We obtain convergence results for a whole range of parameters describing the probabilities in the randomized method or the greedy choice strategy in the Gauss-Southwell-type methods. We identify those choices which make our convergence bounds best possible. Our main tool is to use weighted l1-norms to measure the residuals. A major result is that the best convergence bounds that we obtain for the expected values in the randomized algorithm are as good as the best for the deterministic, but more costly algorithms of Gauss-Southwell type. Numerical experiments illustrate the convergence of the method and the bounds obtained. Comparisons with the randomized Kaczmarz method are also presented.
Semiclassical dynamics of electrons in space-time crystal: Magnetization, polarization, and current response

description: A space-time crystal is defined as a quantum mechanical system with both spatial and temporal periodicity. Such a system can be described by the Floquet-Bloch (FB) theory. We first formulate a semiclassical theory by constructing a wave-packet through the superposition of the FB wave functions and derive the equations of motion of FB electrons subjected to slowly varying external fields (not to be confused with the fast-changing Floquet drive), revealing behaviors similar to ordinary Bloch electrons but with quantities modified in the Floquet context. Specifically, we study local magnetic moment due to the self-rotation of the wave-packet, a contribution to total magnetization from the Berry curvature in k-space, and the polarization of a fully occupied FB band. Based on the semiclassical theory, we can also show the fingerprint of the energy flow in such an energy-non-conserved system. We then discuss the density matrix of a FB system attached to a thermal bath, which allows us to investigate quantities involving many electrons in the non-interacting limit. As an application, we calculate the intrinsic current response in an oblique spacetime metal showing the non-equilibrium nature of the FB system. The current response can also be related to the acoustoelectric effect. Overall, we develop a systematic approach for studying space-time crystals and provide a powerful tool to explore the electronic properties of this exotic system with coupled space and time.

Measurement of the mass difference between top quark and antiquark in pp collisions at sqrt(s) = 8 TeV
Creators: name: CMS Collaboration

Year: 2016
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Delta m[t] = m[t] - m[t-bar]) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state. The analysis is based on data corresponding to an integrated luminosity of 19.6 inverse femtobarns collected by the CMS experiment at the LHC, and yields a value of Delta m[t] = -0.15 +/- 0.19 (stat) +/- 0.09 (syst) GeV, which is consistent with the SM expectation. This result is significantly more precise than previously reported measurements.

Determinants of Life Insurance Demand in Ethiopia
Creators: name: Tigest, Deresse
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: One of the ways of protection a family in case of hardships in life, life insurance is a very important and necessary protection. Among the different problem people face in life are; the breadwinner dies or is disabled and cannot generate income. It also uses for saving purpose and it pays the sum assured in case of maturity the insured can take loans from the saved amount. Although the performance of the insurance industry is closely linked to economic conditions, the life insurance business has been experienced low level of development in Ethiopia. This study's aimed to investigate determinants of life insurance demand in Ethiopia. Ordinary Least Squares (OLS) regression was used to examine the effect of level of income, premium of life insurance, life expectancy, education, financial deepening and inflation on life insurance demand in Ethiopia over a period of 30 years from 1987/1988 to 2016/2017. The collected secondary data were analyzed with multiple regression analysis by using Eviews8. In this study correlation analysis was carried out to show the direction of relationships among the dimensions included in the model. Moreover, regression analysis was conducted to determine the predictive values of the variables. The findings revealed that life expectancy has statistically noticeable negative effect on the life insurance demand in Ethiopia. In addition to that, results shows that the education, per capita income and financial deepening have statistically significant positive influence on life insurance demand in Ethiopia. The other findings discovered that premium of life insurance and inflation has insignificant impact on life insurance demand in Ethiopia for the study period. Based on this finding, the researcher recommended that the government tries to give much emphasis in increasing real income of the people, insurance education for tertiary levels by life insurance companies and national bank of Ethiopia give training for domestic actuaries to support life insurance industry.
Classical and quantum metrology of the Lieb-Liniger model

description: We study the classical and quantum Fisher information for the Lieb-Liniger model. The Fisher information has been studied extensively when the parameter is inscribed on a quantum state by a unitary process, e.g., Mach-Zehnder or Ramsey interferometry. Here, we investigate the case that a Hamiltonian parameter to be estimated is imprinted on eigenstates of that Hamiltonian, and thus is not necessarily encoded by a unitary operator. Taking advantage of the fact that the Lieb-Liniger model is exactly solvable, the Fisher information is determined for periodic and hard-wall boundary conditions, varying number of particles, and for excited states of type-I and type-II in the Lieb-Liniger terminology. We discuss the dependence of the Fisher information on interaction strength and system size, to further evaluate the metrological aspects of the model. Particularly noteworthy is the fact that the Fisher information displays a maximum when we vary the system size, indicating that the distinguishability of the wavefunctions is largest when the Lieb-Liniger parameter is at the crossover between the Bose-Einstein condensate and Tonks-Girardeau limits. The saturability of this Fisher information by the absorption imaging method is assessed by a specific modeling of the latter.

Schlüsselqualifikationen im Kontext der Hochschulreform

Year: 2002
Subjects: subject: 370

description: Im Rahmen der Hochschulreform wird seit einigen Jahren eine öffentliche Debatte über die Effizienz von Studium und Lehre an deutschen Universitäten geführt. BildungspolitikerInnen fordern, das Studium solle insgesamt nachhaltiger werden und Qualifikationen und Kompetenzen vermitteln, die stärker an den konkreten Anforderungen des heutigen gesellschaftlichen Lebens, an der realen Berufswelt, ausgerichtet sind. Auch die Verbände der Wirtschaft beteiligen sich an dieser Diskussion unter dem Hinweis, dass eine qualifizierte (Aus-) Bildung von Fach- und Führungskräften ein wesentlicher Standortvorteil bei einer internationalen Konkurrenz um globale Märkte sei. Standen zunächst quantitative Kennwerte wie Studiendauer, Wechsel- und Abbruchquoten im Vordergrund der Debatte (Deutscher Hochschulverband 1990), so hat sich inzwischen innerhalb und außerhalb der Universitäten eine Auseinandersetzung über die Qualität universitärer Lehr-Lern-Prozesse entwickelt. Durch Novellierungen des Hochschulrahmengesetzes und der Universitätsgesetze der Länder wird versucht, die Strukturreform der Hochschulen mit dem Ziel voranzutreiben, Studium und Lehre an den Hochschulen zu verbessern. Es soll eine stärkere Orientierung an externen vor allem beruflichen - Anforderungen stattfinden. Eine weitergehende Forderung ist, die Bildungsziele der Universität um die Entwicklung von außerwissenschaftlichen und fachübergreifenden (Schlüssel-) Kompetenzen zu erweitern (vgl. Chur 2000). Diese Diskussionen und Forderungen werfen aber eine Reihe von Fragen auf: Über welche Kompetenzen und Qualifikationen wird diskutiert? Da die notwendigen Kompetenzen, will man den Verlautbarungen der letzten Jahre glauben, bislang nicht oder nicht im ausreichenden Maße an den Hochschulen vermittelt wurden, schließt sich die drängende Frage an, wie und in welcher Form können diese vermittelt werden.

description: Quantum systems driven by strong oscillating fields are the source of many interesting physical phenomena. In this work, we experimentally study the dynamics of a two-level system of a single spin driven in the strong-driving regime where the rotating-wave approximation is not valid. This two-level system is a subsystem of a single Nitrogen-Vacancy center coupled to a first-shell $^{13}$C nuclear spin in diamond at a level anti-crossing point that occurs in the $m_{s}=\pm1$ manifold when the energy level splitting between the $m_{s}$ = $+1$ and $-1$ spin states due to the static magnetic field is $\approx$ 127 MHz, which is roughly equal to the spectral splitting due to the $^{13}$C hyperfine interaction. The transition frequency of this electron spin two-level system in a static magnetic field of 28.9 G is 1.7 MHz and it can be driven only by the $z$-component of the RF field. Electron spin Rabi frequencies in this system can reach tens of MHz even for moderate RF powers. The simple sinusoidal Rabi oscillations that occur when the amplitude of the driving field is much smaller than the transition frequency become complex when the driving field strength is comparable or greater than the energy level splitting. We observe that the system oscillates faster than the amplitude of the driving field and the response of the system shows multiple frequencies.

description: The existence of eV-mass sterile neutrinos is not ruled out because of persistent experimental anomalies. Upcoming multi-messenger detections of neutron-star merger remnants could provide indirect constraints on the existence of these particles. We explore the active-sterile flavor conversion phenomenology in a two-flavor scenario (1 active + 1 sterile species) as a function of the sterile neutrino mixing parameters, neutrino emission angle from the accretion torus, and temporal evolution of the merger remnant. The torus geometry and the neutron richness of the remnant are responsible for the occurrence of multiple resonant active-sterile conversions. The number of resonances strongly depends on the neutrino emission direction above or inside the remnant torus and leads to large production of sterile neutrinos (and no antineutrinos) in the proximity of the polar axis as well as more sterile antineutrinos than neutrinos in the equatorial region. As the black hole torus evolves in time, the shallower baryon density is responsible for more adiabatic flavor conversion, leading to larger regions of the mass-mixing parameter space being affected by flavor mixing. Our findings imply that the production of sterile states could have indirect implications on the disk cooling rate, its outflows, and related electromagnetic observables which remain to be assessed.

Study on the Mechanism of Arsenic‑Induced Lung Kidney Based on SWATH Proteomics Technology-Part1
Creators: name: Shen, Liming
Publisher: name: figshare
Year: 2023
Subjects: Proteomics and metabolomics

description: Arsenic (As) pollution affects hundreds of millions worldwide, and As is a recognized human carcinogen. Humans can be exposed to arsenic through the atmosphere, groundwater, and food. Renal excretion of arsenic is known to be the body’s main route of arsenic removal. Epidemiology suggests that arsenic exposure can lead to chronic kidney disease and kidney cancer, but the exact mechanisms of arsenic-induced kidney damage are unknown. This study aimed to investigate the mechanism of arsenic-induced kidney injury in SD (Sprague Dawley) rats by examining the changes in the expression levels of relevant proteins induced by sodium arsenite in kidney tissues using the SWATH-MS method. The results showed that arsenic exposure led to abnormal expression of proteins related to the mitochondrial respiratory chain, mitochondrial membrane, and proximal tubule, resulting in dysfunction of essential pathways related to these proteins, thus inducing kidney injury. Furthermore, we validated the changes in Cycs, COX6c, and PHB2 by protein immunoblot analysis, and the changes were consistent with the proteomic results. We found that the mechanism of arsenic-induced kidney injury may be related to oxidative stress, proximal renal tubular acidosis, and mitochondrial autophagy.

description: We develop NL2INTERFACE to explore the potential of generating usable interactive multi-visualization interfaces from natural language queries. With NL2INTERFACE, users can directly write natural language queries to automatically generate a fully interactive multi-visualization interface without any extra effort of learning a tool or programming language. Further, users can interact with the interfaces to easily transform the data and quickly see the results in the visualizations.

description: We investigate the nature of the quantum phase transition out of charge-density-wave phase in the spinless fermion model with nearest- and next-nearest-neighbor interaction at one-third filling. Using an extensive Density Matrix Renormalization Group (DMRG) simulations we show that the transition changes it nature. We show that for weak next-nearest-neighbor coupling the transition is of Kosterlitz-Thouless type in agreement with bosonisation predictions. We also provide strong numerical evidences that for large next-nearest-neighbor repulsion the transition belongs to the Pokrovsky-Talapov univerality class describing a non-conformal commensurate-incommensurate transition. Finally, we argue that the change of the nature of the transition is a result of incommensurability induced by frustration and realized even at zero doping. The implications in the context of XXZ chain with next-nearest-neighbor Ising interaction is briefly discussed.

description: In this paper, we discuss P(n), the number of ways in which a given integer n may be written as a sum of primes. In particular, an asymptotic form P_as(n) valid for n towards infinity is obtained analytically using standard techniques of quantum statistical mechanics. First, the bosonic partition function of primes, or the generating function of unrestricted prime partitions in number theory, is constructed. Next, the density of states is obtained using the saddle-point method for Laplace inversion of the partition function in the limit of large n. This directly gives the asymptotic number of prime partitions P_as(n). The leading term in the asymptotic expression grows exponentially as sqrt[n/ln(n)] and agrees with previous estimates. We calculate the next-to-leading order term in the exponent, porportional to ln[ln(n)]/ln(n), and show that an earlier result in the literature for its coefficient is incorrect. Furthermore, we also calculate the next higher order correction, proportional to 1/ln(n) and given in Eq.(43), which so far has not been available in the literature. Finally, we compare our analytical results with the exact numerical values of P(n) up to n \sim 8 10^6. For the highest values, the remaining error between the exact P(n) and our P_as(n) is only about half of that obtained with the leading-order (LO) approximation. But we also show that, unlike for other types of partitions, the asymptotic limit for the prime partitions is still quite far from being reached even for n \sim 10^7.

description: Das Problem der Fehler beim Lösen von mathematischen Aufgaben ist in der Didaktik der Mathematik ein wichtiges Thema. Trotzdem kann man in der Literatur nicht viele der Analyse von Fehlern gewidmete Arbeiten vorfinden. In unserem Beitrag möchten wir uns mit einer Klasse von Fehlern beschäftigen, die ziemlich häufig bei unseren Studenten vorkommen. Es sind Fehler, die eine große Resistenz aufweisen. Es ist fraglich ob man diese Fehler als Miskonzepte auffassen kann, da in anderen Kontexten machen denselben Studenten diese Fehler nicht, und wenn befragt, geben sie meistens eine korrekte Antwort. Es geht um das Anwenden von vereinfachten Regeln, welche in einem komplexen Ausdrucke einfach mit den Komponenten arbeiten, ohne auf das Ganze Bezug zu nehmen.

description: There is growing belief that the next decade will see the emergence of sensing devices based on the laws of quantum physics that outperform some of our current sensing devices. For example, in frequency estimation, using a probe prepared in an entangled state can, in principle, lead to a precision gain compared to a probe prepared in a separable state. Even in the presence of some forms of decoherence, it has been shown that the precision gain can increase with the number of probe particles $N$. Usually, however, the entangled and separable state preparation and readout times are assumed to be negligible. We find that a probe in a maximally entangled (GHZ) state can give an advantage over a separable state only if the entangled state preparation and readout times are lower than a certain threshold. When the probe system suffers dephasing, this threshold is much lower (and more difficult to attain) than it is for an isolated probe. Further, we find that in realistic situations the maximally entangled probe gives a precision advantage only up to some finite number of probe particles $N_\text{cutoff}$ that is lower for a dephasing probe than it is for an isolated probe.

description: We present a simple and systematic procedure to determine the effective dynamics of a Brownian particle coupled to a rapidly fluctuating correlated medium, modeled as a scalar Gaussian field, under spatial confinement. The method allows us, in particular, to address the case in which the fluctuations of the medium are suppressed in the vicinity of the particle, as described by a quadratic coupling in the underlying Hamiltonian. As a consequence of the confinement of the correlated medium, the resulting effective Fokker-Planck equation features spatially dependent drift and diffusion coefficients. We apply our method to simplified fluid models of binary mixtures and microemulsions near criticality containing a colloidal particle, and we analyze the corrections to the stationary distribution of the particle position and the diffusion coefficient.

description: Vier axiomatische Perspektiven richten sich auf ein Skandalon: Daß trotz zunehmender Probleme, Krisen, Katastrophen und Desaster, die ausschließlich durch organisierte Arbeit gemildert werden können, Millionen von Menschen aus organisierter Arbeit ausgeschlossen sind. Die Axiome sind: Alles, was Menschen zur Sicherung ihres Lebens brauchen, müssen sie sich erarbeiten; grundsätzlich haben Menschen Bedürfnisse und zugleich das Vermögen, sich die Mittel zur Stillung der Bedürfnisse zu erarbeiten; die Entsprechung von Bedürfnissen und Arbeitsvermögen ist durch Geld ideologisch gespalten; daß Millionen von Menschen in Not leben, ist hauptsächlich Folge der politischen Unfähigkeit, gesellschaftlich erforderliche Arbeit zu organisieren. Da jede gesellschaftliche Entwicklung von orientierendem Handeln bestimmt wird, kann angesichts zunehmender Not nur geschlossen werden: Die vorherrschenden Handlungsorientierungen von Personen und Institutionen, die - gewollt oder ungewollt - Lebenslagen von gesellschaftlichen Systemen bestimmen, sind einem not-wendigen Handeln gegenüber unangemessen. Insbesondere ist die politisch-ideologische Wahrnehmung der Funktionen von Geld als Mittel zur Organisation gesellschaftlich erforderlicher Arbeit zu Lasten steigender Bevölkerungskreise unterentwickelt. Statt die symbolische Bedeutung von Geld für Leistungsanspruch und Leistungsversprechen konsequent zur gesellschaftlichen Organisation von erforderlicher Arbeit zu nutzen, wird Geld als unmittelbare Leistung mißverstanden. Doch Geld stillt keine Lebensbedürfnisse - es läßt sich nicht essen; es heilt auch keine Wunden, weder in Gesellschaft, noch in Natur.

description: Let $F$ be an algebraically closed field of characteristic zero, and $G$ be a finite abelian group. If $A=\oplus_{g\in G} A_g$ is a $G$-graded algebra, we study degree-inverting involutions on $A$, i.e., involutions $*$ on $A$ satisfying $(A_g)^*\subseteq A_{g^{-1}}$, for all $g\in G$. We describe such involutions for the full $n\times n$ matrix algebra over $F$ and for the algebra of $n\times n$ upper triangular matrices.

Enskog kinetic theory of binary granular suspensions: heat flux and stability analysis of the homogeneous steady state

description: The Enskog kinetic theory of multicomponent granular suspensions employed previously [Gómez González, Khalil, and Garzó, Phys. Rev. E \textbf{101}, 012904 (2020)] is considered further to determine the four transport coefficients associated with the heat flux. These transport coefficients are obtained by solving the Enskog equation by means of the application of the Chapman--Enskog method around the local version of the homogeneous state. Explicit forms of the heat flux transport coefficients are provided in steady-state conditions by considering the so-called second Sonine approximation to the distribution function of each species. Their quantitative variation on the control parameters of the mixture (masses and diameters, coefficients of restitution, concentration, volume fraction, and the background temperature) is demonstrated and the results show that in general the dependence of the heat flux transport coefficients on inelasticity is clearly different from that found in the absence of the gas phase (\emph{dry} granular mixtures). As an application of the general results, the stability of the homogeneous steady state is analyzed by solving the linearized Navier--Stokes hydrodynamic equations. The linear stability analysis (which holds for wavelengths long compared with the mean free path) shows that the transversal and longitudinal modes are always stable with respect to long-enough wavelength excitations. This conclusion agrees with previous results derived for monocomponent and (dilute) bidisperse granular suspensions but contrasts with the instabilities found in previous works in dry (no gas phase) granular mixtures.
