description: Joint radar and communication (JRC) technology has become important for civil and military applications for decades. This paper introduces the concepts, characteristics and advantages of JRC technology, presenting the typical applications that have benefited from JRC technology currently and in the future. This paper explores the state-of-the-art of JRC in the levels of coexistence, cooperation, co-design and collaboration. Compared to previous surveys, this paper reviews the entire trends that drive the development of radar sensing and wireless communication using JRC. Specifically, we explore an open research issue on radar and communication operating with mutual benefits based on collaboration, which represents the fourth stage of JRC evolution. This paper provides useful perspectives for future researches of JRC technology.

description: This report summarises evidence on the prevalence of sleep problems and their relationship with chronic health conditions. It shows that Australian adults commonly report sleep problems, and that getting too much or too little sleep is associated with an increased risk of several conditions, including type 2 diabetes, cardiovascular disease, coronary heart disease, and stroke. Data limitations and opportunities for monitoring sleep are also discussed.

description: Pump-probe experiments are used as a controllable way to investigate the properties of photoexcited semiconductors, in particular, the absorption saturation. We present an experiment-theory comparison for ZnSe quantum wells, investigating the energy renormalization and bleaching of the excitonic resonances. Experiments were performed with spin-selective excitation and above-bandgap pumping. The model, based on the semiconductor Bloch equations in the screened Hartree-Fock approximation, takes various scattering processes into account phenomenologically. Comparing numerical results with available experimental data, we explain the experimental results and find that the electron spin-flip occurs on a time scale of 30 ps.

description: Recently, it has become evident the importance of miRNAs in regulating immune response, as well as immune cell development. During my phD fellow I focused my attention on the relationship B-lymphocytes-microRNA; in particular I examined two the different topics: the microRNA activation in response to oncogenic virus infection and cloning of new microRNA within IBTK gene located in the genomic sequence 6q14.1, which is a hot spot of chromosomal rearrangements in lymphoproliferative disorders. Epstein–Barr virus (EBV), which infects over 90% of the adults, appears to have evolved to exploit the normal biology of B-cell development in order to persist as a life-long asymptomatic infection. Of the genes expressed during viral latency in EBV-associated diseases, LMP1 is the one most implicated in tumor formation. miR-155 plays a critical role in lymphocyte activation in vivo. and is induced by a variety of immune cell stimuli, i.e. toll-like receptor (TLR) ligands, TNF-α, interferon-beta (IFN-β) and antigens [B-cell receptor (BCR) engagement]. Here we show that LMP1 upregulates the expression of miR-155 mainly by activating the NF-κB pathway, which suggests that miR-155 can cooperate in the EBV-mediated transformation of B cells. I. Quinto and G. Scala have recently characterized the Inhibitor of Bruton’s tyrosine kinase (IBtk) gene (accession number AL050333) that encodes three adaptor proteins in cell signalling. Consistently, the human IBTK gene is located in the genomic sequence 6q14.1, which is a hot spot of chromosomal rearrangements in lymphoproliferative disorders. In this study, we have addressed whether the IBTK gene might play a role in transcription regulation as source of miRNAs. By bioinformatics analysis, we identified four putative precursors of miRNA (pre-miR) encoded by three distinct introns and the 3’ un-translated region (3’UTR) of the IBTK gene. Of them, only the pre-miR-IBTK3 encoded by intron 26 occurred in vivo, and was the effective substrate of RNase III Dicer.

description:  

A partir del análisis de los trabajos que Néstor García Canclini (1939) elaboró acerca de la obra literaria de Julio Cortázar, Macedonio Fernández y Octavio Paz entre 1968 y 1972, en este artículo nos proponemos identificar qué interrogantes acerca de lo estético surgieron al reflexionar sobre los cuentos, novelas y poesías de dichos autores. Una de las cuestiones que aparecen invisibilizadas en las discusiones y los debates al interior de los estudios vinculados a la antropología, la comunicación o la sociología del arte, es cómo García Canclini, Licenciado en Filosofía de la Universidad Nacional de La Plata (UNLP), Doctor en Filosofía por la UNLP y por la Universidad de París X-Nanterre, se fue desplazando de los estudios estrictamente filosóficos hacia las reflexiones estéticas en un sentido amplio y en particular hacia la producción literaria y artística. Los interrogantes estéticos que nos proponemos indagar, permitirán aproximarnos a estos primeros análisis del filósofo argentino como un proceso de interpretación en clave de cuestionamiento de todo realismo en el campo artístico y literario.

description: Fanconi anemia (FA) is a complex cancer susceptibility disorder associated with defects in the repair of DNA interstrand cross-links (ICLs) resulting in occasional developmental defects and in ICL hypersensitivity of patient cells, yet the precise role of the FA proteins during DNA repair has remained unclear. I will present evidence that FA counteracts illegitimate repair of DNA lesions by non-homologous end joining (NHEJ). FCD-2 has proven to be involved in the choice of repair pathways: 1) fcd-2 mutants show an increase in spo-11 dependent RAD-51 foci and in germline apoptosis, 2) in genetic backgrounds where chiasma formation is abrogated (such as msh-4 and syp-2) resolves in less than the expected 12 DAPI stained bodies at diakinesis, such bodies are the results of chromosome fusions also involving non-homologous chromosomes (as demonstrated by FISH), 4) in the contemporary absence of FCD-2 protein, crossovers and NHEJ (i.e. in the triple mutants fcd-2; syp-2;lig-4 and fcd-2; msh-4;lig-4) we observe more than 12 DAPI stained bodies at diakinesis, a phenotype reminiscent of what observed in brc-1;syp-2 and brc-1;msh-4 double mutants (brc-1 being the ortholog of human BRCA1, see Adamo et al. 2008 enclosed). Furthermore, other fcd-2 mutant phenotypes such as interstrand cross-linking sensitivity and hypermutation are due to promiscuous use of NHEJ.

description: The beta function of a two-dimensional massless Dirac Hamiltonian subject to a random scalar potential, which e.g., underlies the theoretical description of graphene, is computed numerically. Although it belongs to, from a symmetry standpoint, the two-dimensional symplectic class, the beta function monotonically increases with decreasing $g$. We also provide an argument based on the spectral flows under twisting boundary conditions, which shows that none of states of the massless Dirac Hamiltonian can be localized.

description: New science and new technology need new materials and new concepts. In this respect, biological matter can play a primary role because it is a material with interesting and innovative features that have found several applications in technology, from highly sensitive sensors for medical treatments to devices for energy harvesting. Furthermore, most of its phenomenology remains unclear thus giving new hints for speculative investigations. In this letter, we explore the possibility to use a well-known photosensitive protein, the Reaction Center of Rhodobacter Sphaeroides, to build up an electrical pH sensor, i.e., a device able to change its resistance depending on the pH of the solution in which it crystalizes. By using a microscopic model successfully tested on analogue proteins, we investigate the electrical response of the Reaction Center single protein under different conditions of applied bias, showing the feasibility of the bio-rheostat hypothesis. As a matter of facts, the calculated resistance of this protein grows of about 100% when going from a pH = 10 to a pH = 6.5. Moreover, calculations of the current voltage characteristics well agree with available experiments performed with a current atomic force microscopy under neutral conditions. All findings are in qualitative agreement with the known role of pH in biochemical activities of Reaction Center and similar proteins, therefore supporting a proof-of-concept for the development of new electron devices based on biomaterials.

description: Detection methods are available for several known covert channels. However, a type of covert channel that received little attention within the last decade is the "message ordering" channel. Such a covert channel changes the order of PDUs (protocol data units, i.e. packets) transferred over the network to encode hidden information. The advantage of these channels is that they cannot be blocked easily as they do not modify header content but instead mimic typical network behavior such as TCP segments that arrive in a different order than they were sent. Contribution: In this paper, we show a protocol-independent approach to detect message ordering channels. Our approach is based on a modified compressibility score. We analyze the detectability of message ordering channels and whether several types of message ordering channels differ in their detectability. Results: Our results show that the detection of message ordering channels depends on their number of utilized PDUs. First, we performed a rough threshold selection by hand, which we later optimized using the C4.5 decision tree classifier. We were able to detect message ordering covert channels with an accuracy and F1 score of >= 99.5% and a false-positive rate < 1% and < 0.1% if they use sequences of 3 or 4 PDUs, respectively. Simpler channels that only manipulate a sequence of two PDUs were detectable with an accuracy and F1 score of 94.5% and were linked to a false-positive rate of 5.19%. We thus consider our approach suitable for real-world detection scenarios with channels utilizing 3 or 4 PDUs while the detection of channels utilizing 2 PDUs should be improved further.

Les résultats ont été catégorisés à l’aide de la théorie de McGill. Résultats : classés en quatre catégories correspondant aux quatre concepts du cadre théorique : personne/famille, environnement, santé et soins infirmiers. Le concept-pont de cette théorie, l’apprentissage, fait le lien entre les quatre autres concepts. Cette synthèse des résultats a permis de faire émerger une liste de recommandations pour la pratique. Discussion : Compte tenu de l’impact du soutien apporté par le personnel soignant, une formation complémentaire auprès des infirmières dans le but d’affiner leurs compétences en communication et en soutien psychologique est à envisager. Une approche indirecte des parents est pratiquée en Europe mais paraît difficilement transférable en Suisse. Des études supplémentaires, nationales, permettraient d’avoir plus d’informations sur le sujet délicat du don d’organes pédiatriques et d’affiner les résultats trouvés.

description: The structural and dynamic properties of silica melts under high pressure are studied using molecular dynamics (MD) computer simulation. The interactions between the ions are modeled by a pairwise-additive potential, the so-called CHIK potential, that has been recently proposed by Carre et al. The experimental equation of state is well-reproduced by the CHIK model. With increasing pressure (density), the structure changes from a tetrahedral network to a network containing a high number of five- and six-fold Si-O coordination. In the partial static structure factors, this change of the structure with increasing density is reflected by a shift of the first sharp diffraction peak towards higher wavenumbers q, eventually merging with the main peak at densities around 4.2 g/cm^3. The self-diffusion constants as a function of pressure show the experimentally-known maximum, occurring around a pressure of about 20 GPa.

description: El testimonio trae consigo vida. Cuando Giorgio Agamben estudia los relatos sobre los campos de concentración de la Alemania del Tercer Reich y elabora su teoría sobre el testimonio en Lo que queda de Auschwitz. El archivo y el testigo (Homo saccer III), sostiene que “[s]i no hay articulación entre el viviente y el lenguaje, si el yo queda suspendido en esta separación, entonces puede darse testimonio” (2014: 137). El testimonio encuentra su espacio en el no-lugar de la articulación entre el lenguaje y la vida, la bíos y la zoé, lo humano y lo in-humano, en el no-lugar que (no) existe entre la lírica y el horror, generando un diálogo posible. En este no-lugar se ubica la reciente publicación de María Eugenia Villalonga, la cual estudia el campo intelectual y sus producciones durante la represión cultural que se dio en la última dictadura cívico-militar en la Argentina (1976-1983), recogiendo voces, experiencias, testimonios de una contra-cultura que se tejía en los márgenes del horror totalitario. Desde allí, su estudio propone poner estos testimonios a circular, retratar el cuadro de una época y, al calor de estos relatos, ver la vida cómo ocurre

description: We consider the quantum mechanical transport of (coherent) excitons on small-world networks (SWN). The SWN are build from a one-dimensional ring of N nodes by randomly introducing B additional bonds between them. The exciton dynamics is modeled by continuous-time quantum walks and we evaluate numerically the ensemble averaged transition probability to reach any node of the network from the initially excited one. For sufficiently large B we find that the quantum mechanical transport through the SWN is, first, very fast, given that the limiting value of the transition probability is reached very quickly; second, that the transport does not lead to equipartition, given that on average the exciton is most likely to be found at the initial node.

Semi-analytic models for the characterization of microstrips
Creators: name: Assante, Dario
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: Aim of this thesis is that to furnish some methodologies for the accurate evaluation of the electromagnetic characteristics of a microstrip. This results particularly useful for the extraction of equivalent circuital parameters, needed from circuit simulators to study more complex structures. From an analysis of the available models in literature, it is possible to find that some approximations are usually assumed to simplify the treatment. It can be observed that it is usual to neglect the conductive losses, that nevertheless result more and more remarkable with the increase of the density of the circuits. Besides, the existing models for the analysis of microstrips don't generally take into account the thickness of the structure, if not in a perturbative way. This thesis has the objective to propose some models that try to eliminate or however to reduce the approximation around the finite conductivity and the finite thickness of a microstrip.
In the first chapter, general aspects of the microstrips are introduced, shortly examining its uses and the constructive aspects.
In the second chapter a lossless microstrip of infinitesimal thickness is examined. Different kinds of sources are examined. The aim of the chapter is to introduce the method that will be used in future.
In the third chapter, a microstrip of infinitesimal thickness and finite conductibility is examined. Then the method is generalized to the case of an arbitrary number of coupled microstrips.
In the fourth chapter, it is shortly presented a variation of the method previously exposed, studying the problem of a thick strip in the free space. Then, a microstrip of finite thickness is examined.
In the thesis, also the computational aspects related to the convergence of the method and to the numerical treatment of the integrals.
Dynamic soliton-mean flow interaction with nonconvex flux

description: The interaction of localised solitary waves with large-scale, time-varying dispersive mean flows subject to nonconvex flux is studied in the framework of the modified Korteweg-de Vries (mKdV) equation, a canonical model for nonlinear internal gravity wave propagation in stratified fluids. The principal feature of the studied interaction is that both the solitary wave and the large-scale mean flow -- a rarefaction wave or a dispersive shock wave (undular bore) -- are described by the same dispersive hydrodynamic equation. A recent theoretical and experimental study of this new type of dynamic soliton-mean flow interaction has revealed two main scenarios when the solitary wave either tunnels through the varying mean flow that connects two constant asymptotic states, or remains trapped inside it. While the previous work considered convex systems, in this paper it is demonstrated that the presence of a nonconvex hydrodynamic flux introduces significant modifications to the scenarios for transmission and trapping. A reduced set of Whitham modulation equations, termed the solitonic modulation system, is used to formulate a general, approximate mathematical framework for solitary wave-mean flow interaction with nonconvex flux. Solitary wave trapping is conveniently stated in terms of crossing characteristics for the solitonic system. Numerical simulations of the mKdV equation agree with the predictions of modulation theory. The developed theory draws upon general properties of dispersive hydrodynamic partial differential equations, not on the complete integrability of the mKdV equation. As such, the mathematical framework developed here enables application to other fluid dynamic contexts subject to nonconvex flux.

description: In semi-supervised fuzzy clustering, this paper extends the traditional pairwise constraint (i.e., must-link or cannot-link) to fuzzy pairwise constraint. The fuzzy pairwise constraint allows a supervisor to provide the grade of similarity or dissimilarity between the implicit fuzzy vectors of a pair of samples. This constraint can present more complicated relationship between the pair of samples and avoid eliminating the fuzzy characteristics. We propose a fuzzy discriminant clustering model (FDC) to fuse the fuzzy pairwise constraints. The nonconvex optimization problem in our FDC is solved by a modified expectation-maximization algorithm, involving to solve several indefinite quadratic programming problems (IQPPs). Further, a diagonal block coordinate decent (DBCD) algorithm is proposed for these IQPPs, whose stationary points are guaranteed, and the global solutions can be obtained under certain conditions. To suit for different applications, the FDC is extended into various metric spaces, e.g., the Reproducing Kernel Hilbert Space. Experimental results on several benchmark datasets and facial expression database demonstrate the outperformance of our FDC compared with some state-of-the-art clustering models.

To illustrate our approach, we determine the cyclicity of the annuli of two particular reversible systems.

description: The X-ray transient MAXI J1631-479 went into outburst on 2018 December 21 and remained active for about seven months. Owing to various constraints it was monitored by NICER only during the decay phase of the outburst for about four months. The NICER observations were primarily in the soft state with a brief excursion to the hard intermediate state. While the soft state spectrum was dominated by thermal disk emission, the hard intermediate state spectrum had maximum contribution from the thermal Comptonization. Almost all intermediate-state power spectra had a Type-C low frequency quasi-periodic oscillation (within 4 - 10 Hz), often accompanied by a harmonic component. The frequency of these oscillations increased and the fractional rms decreased with inner-disk temperature suggesting a geometric origin. One observation in the middle of the outburst during the hard intermediate state had two non-harmonically related peaks. While one of them was definitely a Type-C QPO, the identification of the other one is uncertain. The rms spectra during the intermediate state had a hard shape from above 1 keV. Below 1 keV the shape could not be constrained in most cases, while only a few observations showed a rise in amplitude.

description: The lecture notes describe the Delaunay Tessellation Field Estimator for Cosmic Web analysis. The high sensitivity of Voronoi/Delaunay tessellations to the local point distribution is used to obtain estimates of density and related quantities. The adaptive and minimum triangulation properties of Delaunay tessellations are utilized for interpolation to continuous volume-covering density and velocity fields. The adaptivity to the local density and geometry preserves three key characteristics of the cosmic matter distribution: 1) its hierarchical nature,2) its anisotropic weblike morphology, 3) the presence and structure of voids. The lecture notes discuss the mathematical context and background of the DTFE method, in essence a first order version of Natural Neighbour methods, smooth and higher order spatial interpolation techniques. This is followed by an outline of the DTFE procedure. A series of tests on spatially complex point distributions provides quantitative information on its performance and noise characteristics. We conclude with a few cosmological applications. The reconstruction of the spatial weblike patterns in N-body simulations and in the 2dFGRS provide a visual impression of DTFE's performance. The analysis of the velocity divergence pdf and maps obtained of the velocity flow in the Local Universe (implied by PSCz) illustrate its promise for probing the dynamics of cosmic structure. The Watershed Void Finder (Platen et al. 2007), for the study of voids, and Multiscale Morphology Filter (Aragon-Calvo et al. 2007), for identifying and analyzing weblike networks of filaments, sheets and clusters, are based upon DTFE density fields. We also mention SimpleX, a related random lattice radiative transfer formalism (Ritzerveld & Icke 2006).

description: Lors de la crise migratoire qui touche actuellement l’Europe, nous nous sommes penchées sur les requérants d’asile mineurs non-accompagnés, c’est-à-dire les jeunes personnes âgées entre 14 et 17 ans qui arrivent en Suisse sans leur famille. Nous nous sommes demandées quel est le rôle de l’infirmier1 dans la prise en charge de ces personnes ayant souvent été victimes de traumatismes. L’objectif de cette recherche a été de trouver des outils qui amélioraient le dépistage du stress posttraumatique chez les personnes mineures requérantes d’asile lors de la prise en charge infirmière malgré les différences culturelles. Nous avons utilisé comme méthode les bases de données Pubmed, CINAHL et PsycINFO afin de cibler six articles en lien avec notre question de recherche. Nous les avons présentés et analysés sous formes de tableaux synthétiques. Les résultats ont été mis en lien avec le cadre théorique de Meleis. Il ressort des articles que l’infirmer est souvent, la première personne avec qui la personne réfugiée entre en contact lors de la prise en charge médicale. Le rôle de l’infirmier est de garantir une continuité des soins, malgré les difficultés de la barrière culturelle et le manque de formation de la part du soignant. A travers nos lectures, nous avons relevé deux pistes d’amélioration. Une première qui vise à améliorer la formation infirmier dans la prise en charge de personnes réfugiées. La seconde qui concerne un outil de dépistage du stress post-traumatique.

description: This study investigated the sources of support available to mothers of children with Down syndrome. Three levels of social interaction were examined: family support; informal support (friends and neighbours), and; formal support (professionals and social institutions). A questionnaire was circulated to thirty-two mothers of children with Down syndrome. The questionnaire surveyed those formal and informal systems which were potential sources of support for mothers. Findings indicated that mothers experiences were differentially affected by their setting. Mothers were generally satisfied with their sources of informal support. In two-parent families fathers were perceived as very supportive of their spouses, while in one-parent families the mothers relied on other sources such as friends, neighbours, and extended family for their support. Urban mothers expressed less satisfaction with formal systems of support than did mothers living in non-urban areas. Findings indicated that perceiving systems of support as supportive may relate to the quality of the services as well as to the availability.

description: Dynamic capabilities theory emerged as a leading framework in the process of value creation for firms. Its core notion complements the premise of the resource-based view of the firm and is considered an important theoretical and management framework in modern information systems research. However, despite DCTs significant contributions, its strength and core focus are essentially in its use for historical firm performance explanation. Furthermore, valuable contributions have been made by several researchers in order to extend the DCT to fit the constantly changing IT environments and other imperative drivers for competitive performance. However, no DCT extension has been developed which allows firms to integrally assess their current state of maturity in order to derive imperative steps for further performance enhancements. In light of empirical advancement, this paper aims to develop a strategic alignment model for IT flexibility and dynamic capabilities and empirically validates proposed hypotheses using correlation and regression analyses on a large data sample of 322 international firms. We conjecture that the combined synergetic effect of the underlying dimensions of a firms IT flexibility architecture and dynamic capabilities enables organizations to cope with changing environmental conditions and drive competitive firm performance. Findings of this study suggest that there is a significant positive relationship between the firms degree of strategic alignment defined as the degree of balance between all dimensions and competitive firm performance. Strategic alignment can, therefore, be seen as an important condition that significantly influences a firms competitive advantage in constantly changing environments. The proposed framework helps firms assess and improve their maturity and alignment of IT flexibility and dynamic capabilities.

The temporal stability of social responses to depressed and nondepressed individuals

description: The purpose of this study was to replicate and extend the findings of previous research addressing Coyne's (1976a) interactional model of depression. The nature and temporal stability of the social responses elicited by mildly depressed and nondepressed individuals were examined. One hundred and thirty-five female undergraduate volunteers were assigned, on the basis of Beck Depression Inventory scores to groups of depressed and nondepressed targets and nondepressed subjects. At Time 1, mildly depressed targets and nondepressed targets were randomly paired with individuals from the subject group. Measures of pre-interaction mood were taken, and each target-subject dyad carried out a 5-minute videotaped "getting acquainted" conversation. Following the conversation, the subject in each dyad completed questionnaires assessing self-reported reactions to her target partner. Approximately 3 weeks later, targets returned for a second (i.e., Time 2) interaction. Depression levels were reassessed at this time and targets were divided into three groups: those who were depressed at Time 1 and remained depressed at Time 2 (n = 15), those who were nondepressed at Time 1 and remained nondepressed at Time 2 (n = 15), and those who were depressed at one time and nondepressed at the other time (n = 15). On this second occasion, targets were paired with new randomly assigned subjects; the procedures followed were identical to those at Time 1. Within- and between-times analyses were carried out on subjects' verbal and nonverbal conversational responses, as well as on their post-interaction self-reports of emotional and cognitive responses to their partners. Results were not supportive of Coyne's interactional model of depression and did not replicate the results of previous investigations. There were only minor differences in subjects' responses to groups of depressed and nondepressed targets at Time 1 and across the two testing occasions. Depressed individuals were not responded to in a more negative fashion than were nondepressed individuals in terms of observed verbal and nonverbal behaviors or self-reported reactions. Results of this investigation lead to the conclusion that social responses to mildly depressed and nondepressed target groups are essentially the same, and that these responses do not change over a 3-week interval, even though the moods of target individuals may change. The validity of laboratory investigations as tests of Coyne's interactional model is questioned, and a "developing relationships" approach to assessing interactional patterns of depressed and nondepressed individuals is proposed.

description: Ficciones fónicas, de Gabriela Milone, se instala en el paso rítmico-afectivo de una escritura en la que la lengua de la teoría es pronunciada por la posesión (lo que hacen las ninfas) lírica. Un estilo “anfibio” –el discurso de las ranas cantando al borde del agua– en el que las citas ocupan un lugar sintácticamente alternativo: los nombres y las referencias parecen ser más bien palabras sometidas a resonancias y variaciones de una serie que citas sustantivas de autoridad. En ocasiones, la progresión se dirige, de manera experimental, a la asociación (libre) fónica, al balbuceo y aún al murmullo.

description: A Molecular Dynamics (MD) study of static and dynamic properties of molten and glassy germanium dioxide is presented. The interactions between the atoms are modelled by the classical pair potential proposed by Oeffner and Elliott (OE) [Oeffner R D and Elliott S R 1998, Phys. Rev. B, 58, 14791]. We compare our results to experiments and previous simulations. In addition, an ab initio method, the so-called Car-Parrinello Molecular Dynamics (CPMD), is applied to check the accuracy of the structural properties, as obtained by the classical MD simulations with the OE potential. As in a similar study for SiO2, the structure predicted by CPMD is only slightly softer than that resulting from the classical MD. In contrast to earlier simulations, both the static structure and dynamic properties are in very good agreement with pertinent experimental data. MD simulations with the OE potential are also used to study the relaxation dynamics. As previously found for SiO2, for high temperatures the dynamics of molten GeO2 is compatible with a description in terms of mode coupling theory.

description: The quantum phase transitions in the one-dimensional asymmetric Hubbard model are investigated with the bosonization approach. The conditions for the phase transition from density wave to phase separation, the correlation functions and their exponents are obtained analytically. Our results show that the difference between the hopping integrals for up- and down-spin electrons is crucial for the happening of the phase separation. When the difference is large enough, the phase separation will appear even if the on-site interaction is small.
