description: Films of close-packed Au nanoparticles are coupled electrodynamically through their collective plasmon resonances. This collective optical response results in enhanced light-matter interactions, which can be exploited in various applications. Here, we demonstrate their application in sensing volatile organic compounds, using methanol as a test-case. Ordered films over several cm2 were obtained by interfacial self-assembly of colloidal Au nanoparticles (~10 nm diameter) through controlled evaporation of the solvent. Even though isolated nanoparticles of this size are inherently non-scattering, when arranged in a close-packed film the plasmonic coupling results in a strong reflectance and absorbance. The in-situ tracking of vapor phase methanol concentration through UV-Vis transmission measurements of the nanoparticle film is first demonstrated. Next, in-situ ellipsometry of the self-assembled films in the Kretschmann (also known as ATR) configuration is shown to yield enhanced sensitivity, especially with phase difference measurements. Our study shows the excellent agreement between theoretical models of the spectral response of self-assembled films with experimental in-situ sensing experiments. At the same time, the theoretical framework provides the basis for the interpretation of the various observed experimental trends. Combining periodic nanoparticle films with ellipsometry in the Kretschmann configuration is a promising strategy towards highly sensitive and selective plasmonic thin-film devices based on colloidal fabrication methods for volatile organic compound (VOC) sensing applications.

description: Optical clocks with unprecedented accuracy of 10^(-18) will lead to innovations in many research areas. All the applications of optical clocks rely on the ability of precisely converting the frequency from one optical clock to another, or particularly to the frequencies in the fiber telecom band for long-distance transmission. Here, we report a low-noise, high precision optical frequency divider. It can realize accurate optical frequency conversion as well as enable precise measurement of optical frequency ratios. By comparing against the frequency ratio between the fundamental and the second harmonic of a 1064 nm laser rather than a second similar system, the optical frequency divider is demonstrated to have a frequency division instability of 6e-19 at 1 s and a fractional frequency division uncertainty of 1.4e-21, nearly three orders of magnitude better than the most accurate optical clocks. It allows optical clocks to be accessible to many precision measurement applications.

description: Recently lead halide nanocrystals (quantum dots) have been reported with potential for photovoltaic and optoelectronic applications due to their excellent luminescent properties. Herein excitonic photoluminescence (PL) excited by two-photon absorption in perovskite CsPbBr3 quantum dots (QDs) have been studied across a broad temperature range from 80K to 380K. Two-photon absorption has been investigated with absorption coefficient up to 0.085 cm/GW at room temperature. Moreover, the photoluminescence excited by two-photon absorption shows a linear blue-shift (0.25meV/K) below temperature of ~220K and turned steady with fluctuation below 1nm (4.4meV) for higher temperature up to 380K. These phenomena are distinctly different from general red-shift of semiconductor and can be explained by the competition between lattice expansion and electron-phonon couplling.Our results reveal the strong nonlinear absorption and temperature-independent chromaticity in a large temperature range from 220K to 380K in the CsPbX3 QDs, which will offer new opportunities in nonlinear photonics, light-harvesting and light-emitting devices.

description: Most industrial processes in real-world manufacturing applications are characterized by the scalability property, which requires an automated strategy to self-adapt machine learning (ML) software systems to the new conditions. In this paper, we investigate an Electroslag Remelting (ESR) use case process from the Uddeholms AB steel company. The use case involves predicting the minimum pressure value for a vacuum pumping event. Taking into account the long time required to collect new records and efficiently integrate the new machines with the built ML software system. Additionally, to accommodate the changes and satisfy the non-functional requirement of the software system, namely adaptability, we propose an automated and adaptive approach based on a drift handling technique called importance weighting. The aim is to address the problem of adding a new furnace to production and enable the adaptability attribute of the ML software. The overall results demonstrate the improvements in ML software performance achieved by implementing the proposed approach over the classical non-adaptive approach.

Stress and influenza classification is a part of Shesop's application for a healthcare devices such as smartwatch, polar and fitbit. The main objective of this paper is to classify a new data and inform whether you are stress, depressed, caught by influenza or not. We will use the heart rate data taken for months in Bandung, analyze the data and find the Heart rate variance that constantly related with the stress and flu level. After we found the variable, we will use the variable as an input to the support vector machine learning. We will use the lagrangian and kernel technique to transform 2D data into 3D data so we can use the linear classification in 3D space. In the end, we could use the machine learning's result to classify new data and get the final result immediately: stress or not, influenza or not.

description: We investigate the impact of turbulent suppression of parallel heat conduction on the cooling of post-flare coronal loops. Depending on the value of the mean free path $λ_T$ associated with the turbulent scattering process, we identify four main cooling scenarios. The overall temperature evolution, from an initial temperature in excess of $10^7$~K, is modeled in each case, highlighting the evolution of the dominant cooling mechanism throughout the cooling process. Comparison with observed cooling times allows the value of $λ_T$ to be constrained, and interestingly this range corresponds to situations where collision-dominated conduction plays a very limited role, or even no role at all, in the cooling of post-flare coronal loops.

description: The SuperNovae Analysis aPplication (SNAP) is a new tool for the analysis of SN observations and validation of SN models. SNAP consists of an open source relational database with (a) observational light curve, (b) theoretical light curve, and (c) correlation table sets, statistical comparison software, and a web interface available to the community. The theoretical models are intended to span a gridded range of parameter space. The goal is to have users to upload new SN models or new SN observations and run the comparison software to determine correlations via the web site. There are looming problems on the horizon that SNAP begins to solve. Namely, large surveys will discover thousands of SNe annually. Frequently, the parameter space of a new SN event is unbounded. SNAP will be a resource to constrain parameters and determine if an event needs follow-up without spending resources to create new light curve models from scratch. Secondly, there is not a rapidly available, systematic way to determine degeneracies between parameters or even what physics is needed to model a realistic SNe. The correlations made within the SNAP system begin to solve these problems.

description: Initial partonic eccentricities in Au+Au collisions at center-of-mass energy $\sqrt{s_{NN}}$ = 200 GeV are investigated using a multi-phase transport model with string melting scenario. The initial eccentricities in different order of harmonics are studied using participant and cumulant definitions. Eccentricity in terms of second-, fourth- and sixth order cumulants as a function of number of participant nucleons are compared systematically with the traditional participant definition. The ratio of the cumulant eccentricities $\varepsilon\left\{4\right\}/\varepsilon\left\{2\right\}$ and $\varepsilon\left\{6\right\}/\varepsilon\left\{4\right\}$ are studied in comparison with the ratio of the corresponding flow harmonics. The conversion coefficients ($v_n/\varepsilon_n$) are explored up to fourth order harmonic based on cumulant method. Furthermore, studies on transverse momentum ($p_T$) and pseudo-rapidity ($η$) dependencies of eccentricities and their fluctuations are presented. As in ideal hydrodynamics initial eccentricities are expected to be closely related to the final flow harmonics in relativistic heavy-ion collisions, studies of the fluctuating initial condition in the AMPT model will shed light on the tomography properties of the initial source geometry.

description: Context: The chemical composition of stars is intimately linked to the Galaxy formation and evolution. Aims: We aim to trace the chemical evolution of the Galactic disk through the inspection of the [X/Fe]-age relations of 24 species from C to Eu. Methods: Using high-resolution and high-signal-to-noise UVES spectra of nine solar twins, we obtained precise estimates of stellar ages and chemical abundances. These determinations have been integrated with additional accurate age and abundance determinations from recent spectroscopic studies of solar twins existing in the literature, comprising superb abundances with 0.01~dex precision. Based on this data set, we outlined the [X/Fe]-age relations over a time interval of 10~Gyr. Results: We present the [X/Fe] - age relations for 24 elements (C, O, Na, Mg, Al, Si, S, K, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Y, Ba, La, Ce, Nd, and Eu). Each different class of elements showed distinct evolution with time that relies on the different characteristics, rates and timescales of the nucleosynthesis' sites from which they are produced. The $α$-elements are characterised by a [X/Fe] decrement as time goes on. Strikingly, an opposite behaviour is observed for Ca. The iron-peak elements show an early [X/Fe] increase followed by a decrease towards the youngest stars. The [X/Fe] for the n-capture elements decrease with age. We also found that both [Mg/Y] and [Al/Y] are precise stellar clocks, with [Al/Y] showing the steepest dependence with age. Conslusions: Knowledge of the [X/Fe]-age relations is a gold mine from which we can achieve a great understanding about the processes that governed the formation and evolution of the Milky Way. Through the reverse engineering of these relations we will be able to put strong constraints on the nature of the stellar formation history, the SNe rates, the stellar yields, and the variety of the SNe progenitors.

Recession and professional & business services employment in the US: no safe haven
Creators: name: Harpel, Ellen
Publisher: name: Povos e Culturas
Year: 2010

description: This paper examines professional and business services (PBS) employment patterns among US metropolitan areas during the recent recession. The PBS sector did not dampen unemployment rates, contrary to past expectations about services sector behavior during the business cycle. The rate of PBS employment loss was greater than the overall job loss rate in most metropolitan areas from 2007-2009, but the behavior was not universal across locations. Further, the professional services component of the PBS sector experienced a lower rate of job loss compared to total job losses, and a diverse set of large metropolitan areas actually gained professional services jobs over this period. By contrast, the administrative services component of the PBS sector experienced a loss in employment that substantially exceeded the overall job loss rate, a pattern seen across all metropolitan areas. Region-specific characteristics, rather than industry or national factors, appear to play an important role in PBS employment trends, but the relative level of professional services versus administrative services employment also matters.

description: We developed a new holmium-doped triple-clad fiber (Ho-3CF), reducing the clad diameter to improve the overlap between pump and doped-core, and the holmium concentration to reduce the influence of ion clustering on the laser efficiency. We illustrate here the performance of this fiber in a laser oscillator configuration. The laser emission is centered at 2.12 $μ$m by a fiber Bragg grating, and the active fiber is pumped in the clad by a 1.94 $μ$m thulium-doped fiber laser. The slope efficiency reaches 73% with respect to absorbed power (60% considering coupled power), for a maximum signal power of 62 W delivered on a quasi single spatial mode (M$^2$=1.2). To the best of our knowledge, this slope efficiency is the highest reported for a high power clad-pumped fiber laser emitting at a wavelength higher than 2.1 $μ$m. We also analyze experimentally the impact of the pump Numerical Aperture (NA), at the input of the Ho-3CF, on the laser efficiency. Finally, we use our numerical simulation to comment on the best choice of pump wavelength.

description: From shoes to ICT (Information and Communication Technology): how a rural area was given the chance to climb out of a crisis in traditional manufacturing industries and improve its prosperity. Local development can be built on innovation through new technologies. In the North of Alsace, France, the ADEC, a local development structure, was created with this very purpose. Can ADEC be seen as a good practice? What are the limits of such a structure? What new steps must be taken to ensure its continuation and effectiveness in the future for all its stakeholders? The ADEC experience shows how a team of deeply committed entrepreneurs and politicians can build a collective project, in coherence with EU policies, over the long-term. Through drawing out some of the key guidelines from the ADEC story, it is possible to transfer partly to other territories some of the ADEC practice.

Magnetobreakdown oscillations of Nernst-Ettingshausen field in layered conductors

description: In the presented report, the Nernst-Ettingshausen effect in layered conductors is investigated. Considering a Fermi surface (FS) consisting of a slightly corrugated cylinder and two corrugated planes distributed periodically in the momentum space, the thermoelectric effects are considered under general assumptions for the value of a magnetic breakdown probability. As a result of an external generalized force, the FS sheets in layered conductors with a multisheet FS appear to be so close that the charge carriers (as a result of magnetic breakdown) can move from one FS sheet to another. In addition, the distribution functions of the charge carriers and the magnetic breakdown oscillations of thermoelectrical field along the normal to the layer, under different values and orientations of the magnetic field, $B$, are calculated. It is shown that if the magnetic field is deflected from the $xz$-plane at an angle $φ$, the oscillation part of a thermoelectrical field along the normal to the layer under condition $\sinφ\tan\vartheta \gg 1$ is mainly determined with the Nernst-Ettingshausen effect.

description: The escape rate of a Brownian particle over a potential barrier is accurately described by the Kramers theory. A quantitative theory explicitly taking the activity of Brownian particles into account has been lacking due to the inherently out-of-equilibrium nature of these particles. Using an effective equilibrium approach [Farage et al., Phys. Rev. E 91, 042310 (2015)] we study the escape rate of active particles over a potential barrier and compare our analytical results with data from direct numerical simulation of the colored noise Langevin equation. The effective equilibrium approach generates an effective potential which, when used as input to Kramers rate theory, provides results in excellent agreement with the simulation data.

description: A cidade da Marinha Grande cresceu após a criação, pelo Estado, da Real Fábrica de Vidros da Marinha Grande, em meados do século XVIII. Com o andar dos tempos, foram-se desenvolvendo uma série de empresas ligadas ao fabrico de vidro, herdeiras das quais são as actuais fábricas de cristalaria e de produção de vidro modelado e de emba-lagem, estas com um elevado grau de sofisticação e altamente competitivas. O espírito empreendedor dos habitantes da Marinha Grande levou-os, partindo da experiência vidreira, a desenvolver outro cluster – o dos moldes – o qual se foi consolidado, tendo resistido ao teste de mercado. Hoje, um novo sector industrial – o dos plásticos – está a emergir no universo empresarial do concelho. A actividade privada de um território deve ser, se não suportada, pelo menos não obstaculizada pelas autoridades públicas, devendo os municípios ser facilitadores do crescimento económico, base fundamental de um desenvolvimento sustentado. Assim, e num município onde a inovação empresarial foi, desde sempre, base do seu sucesso, faz sentido que tome como sua visão MARINHA GRANDE – TERRITÓRIO DE INOVAÇÃO. Este trabalho, tendo como partida o contexto económico referido e a intenção do executivo de ter uma postura facilitadora da actividade empresarial, propõe um caminho de desenvolvimento sustentável que adequa a perspectiva económica e o conhecimento e a inovação com a preservação do ambiente e a atenção aos problemas sociais, contribuindo para o bem-estar dos cidadãos. Propõem-se, assim, os seguintes objectivos operacionais, bem como as acções concretas em que eles se consubstanciam: (i) Promover a Gestão Ambiental Sustentável, (ii) Apoiar a Sustentação da Inovação Empresarial e (iii) Intervir na Coesão Social. Para além destes campos de actuação futura é imprescindível, até para dar a conhecer o município e a sua capacidade produtiva, implementar uma estratégia de comunicação e imagem. Daí que um último objectivo operacional, transversal aos restantes três, tenha sido delineado: Informar e Comunicar.

description: A Agenda 21 Local do município da Nazaré exemplifica a elabo-ração do percurso de um concelho atlântico, agrícola e industrial mas não menos piscatório e turístico no sentido do desenvolvimento sustentável de base local. Um concelho, onde o mar é o mais importante recurso natural: dele vive a comunidade de pescadores, nele assenta a indústria turística local, nele radicam a cultura e as tradições da Vila da Nazaré e nele o município encontra a sua marca identitária. A componente Mar foi objecto de particular atenção no seio da Agenda 21 Local, relevando a relação estreita entre o mar e todas as actividades socioeconómicas, num contexto de transversalidade: activo crítico do desenvolvimento sustentável, factor ambiental por excelência, pleno de desafios e oportunidades à espera de serem aproveitados (aquacultura; construção e reparação naval; turismo, lazer e cultura, incluindo o património cultural subaquático; ciência e tecnologia); outras dimensões não captadas pelos indicadores económicos convencionais, como serviços prestados à sociedade não objecto de transacção de mercado mas com impacto significativo sobre o bem-estar da comunidade (por exemplo, as actividades de recreio, como ir à praia, o valor do cenário que a costa oferece...). No contexto concreto dos recursos, potencia-lidades e fragilidades respectivos, o percurso de desenvolvimento sustentável do município da Nazaré deve orientar-se para a valorização do mar como factor de identidade, imagem e especialização do desenvolvimento, valorizando e qualificando o ambiente, recuperando a identidade urbana, assegurando um futuro turístico para a Vila e para o concelho e sustentando a diversidade da sua base económica.

description: 3D extended field of views (FOVs) of the internal bladder wall facilitate lesion diagnosis, patient follow-up and treatment traceability. In this paper, we propose a 3D image mosaicing algorithm guided by 2D cystoscopic video-image registration for obtaining textured FOV mosaics. In this feasibility study, the registration makes use of data from a 3D cystoscope prototype providing, in addition to each small FOV image, some 3D points located on the surface. This proof of concept shows that textured surfaces can be constructed with minimally modified cystoscopes. The potential of the method is demonstrated on numerical and real phantoms reproducing various surface shapes. Pig and human bladder textures are superimposed on phantoms with known shape and dimensions. These data allow for quantitative assessment of the 3D mosaicing algorithm based on the registration of images simulating bladder textures.

Impactes directos, indirectos e induzidos da actividade termal na economia local: os casos de São Pedro do Sul e Monfortinho

description: As infra-estruturas turísticas localizadas em zonas rurais onde a estrutura económica local tende a ser frágil e pouco diversificada são frequentemente encaradas como motores de crescimento e desenvolvimento local. No entanto, os vários estudos até agora desenvolvidos em Portugal visando investigar o papel desempenhado por aquelas, particularmente estâncias termais, no crescimento e desenvolvimento económico local tendem a ficar-se pela análise do impacte directo nas economias locais – produção, valor acrescentado e emprego gerado pelas actividades directamente beneficiadas pelos gastos dos frequentadores dos estabelecimentos termais. A generalidade dos estudos desenvolvidos até hoje em Portugal tendem a ignorar o efeito multiplicador das estâncias termais nas restantes actividades económicas locais. Este estudo contribui para colmatar tal lacuna ao estimar o impacte económico total (directo, indirecto e induzido) de uma estância termal rural portuguesa na economia local. Para tal, desenvolve modelos de Leontief Fechado para duas economias locais – Monfortinho e São Pedro do Sul, casos de estudo seleccionados por constituírem casos extremos em termos da magnitude do impacte económico local total de uma estância termal rural portuguesa. Dada a desproporção da densidade das interdependências intra-industriais entre as actividades directamente beneficiadas pelas despesas dos frequentadores dos estabelecimentos termais e as restantes actividades econó-micas locais, Monfortinho aproxima-se do que será o impacte económico total mínimo enquanto São Pedro estará próximo do impacte económico máximo gerado por uma estância termal rural portuguesa. As estimativas geradas pelos modelos aqui desenvolvidos sugerem que cada €100 de despesa efectuada pelos frequentadores de um estabelecimento termal rural português gerará um efeito total na economia local que variará entre €140 e €156 em termos de produção local, entre €70 e €80 de valor acrescentado local e entre 0,0051 e 0.0053 empregos medidos em equivalente a tempo de trabalho anual completo.

description: We propose a novel geometric model of three-dimensional topological insulators in presence of an external electromagnetic field. The gapped boundary of these systems supports relativistic quantum Hall states and is described by a Chern-Simons theory with a gauge connection that takes values in the Maxwell algebra. This represents a non-central extension of the Poincaré algebra and takes into account both the Lorentz and magnetic-translation symmetries of the surface states. In this way, we derive a relativistic version of the Wen-Zee term, and we show that the non-minimal coupling between the background geometry and the electromagnetic field in the model is in agreement with the main properties of the relativistic quantum Hall states in the flat space.

description: Qual o papel das empresas enquanto agentes motores do crescimento e desenvolvimento regional? Sublinhe-se de imediato que, num contexto de globalização, logo de concorrência crescente entre territórios e agentes económicos, qualquer estratégia de desenvolvimento regional obriga ao reforço dos seus factores competitivos: para além de assentar nos recursos humanos, materiais e naturais, tem de apostar no reforço da competitividade e correspondente sustentabilidade das empresas (conhecimento e inovação; processos produ-tivos e organizativos), garante da criação de riqueza, de empregos, de coesão social e de sobrevivência económica. A promoção do potencial de crescimento e desenvolvimento económico regional implica uma estratégia que aposte claramente numa crescente abertura e adaptação à inovação do tecido produtivo regional, muitas vezes com criação e consolidação de clusters territoriais de empresas (aumento da produtividade, incremento do empreendedorismo); e não menos, infra-estruturas avançadas, acessibilidades de qualidade e serviços qualificados de apoio, recursos humanos qualificados e competentes, e custos de contexto aceitáveis. A competitividade territorial passa por uma rede urbana equilibrada e estruturada na base do aproveitamento de complementaridades, por uma boa articulação económica entre as cidades e as zonas rurais, por boas acessibilidades intra e inter-regionais, por uma localização menos desequilibrada dos recursos no território, por uma afectação espacial de infra-estruturas que promova o desenvolvimento regional e favoreça a actividade económica; sem esquecer a questão das comunicações e a qualidade ambiental, no seu todo. Na continuidade, merece realce o papel dos poderes públicos e das políticas públicas em promover economias externas e ambientes empresariais mais favoráveis e em reforçar a atractividade regional. Uma atenção especial foi dispensada aos instrumentos de política pública de estímulo às empresas em Portugal, designadamente no âmbito do QREN, 2007-2013, concluindo pela inexistência de uma verdadeira orientação política no sentido de criar reais condições para que todas as regiões possam contribuir plenamente com os seus recursos para o desenvolvimento do país, ao não serem tidas em conta as diferentes condições de partida.

Publisher: name: Povos e Culturas
Year: 2010

description: O estudo parte de uma revisão do conceito de economia social e visa os seguintes objectivos: compreender se a crise actual é conjuntural ou estrutural; clarificar a situação económico-social do distrito de Castelo Branco, ponderando as consequências da crise actual; clari-ficar a situação e as perspectivas de viabilidade das IPSS, Instituições Particulares de Solidariedade Social, e formular propostas para que elas não sejam abaladas pela crise e até contribuam para a debelar, especialmente nos mercados locais. Com base numa análise de diversas entidades estatísticas, conclui- -se que a crise é estrutural e apresenta-se o quadro actual de agravamento da situação económico-social, aliás coincidente com a sensibilidade das IPSS contactadas no âmbito do estudo. Faz-se o desenho da presença de IPSS no distrito e das respostas sociais por elas oferecidas, bem como da sua organização e gestão, dos seus colaboradores e utentes, da sua sustentabilidade financeira e dos constrangimentos com que se deparam. É analisado o seu contributo para as economias locais e o papel na dinamização do empreendedorismo e do voluntariado. Um benchmarking nacional e internacional de Economia Social permite identificar boas práticas de governança e de financiamento. Conclui-se com um conjunto de Recomendações de iniciativas e acções nas seguintes áreas: melhoria do enquadramento normativo e iniciativas públicas; gestão para sustentabilidade; combate à pobreza; potenciação dos impactes da economia social. Destaca-se a necessidade de promover uma maior e melhor cooperação entre as IPSS e entre elas e o Centro Distrital de Segurança Social e as Autarquias Locais, de reforçar o papel do Governo Civil nessa promoção e no aproveitamento das potencialidades da “Rede Social”, de fazer a conciliação entre as exigências de qualidade, previstas para os equipamentos sociais, e a diversidade e quantidade de problemas a abranger, de promover a participação das IPSS na solução dos problemas de desemprego, bem como de dinamizar o desenvolvimento das boas práticas identificadas.

Theories of regional economic development: a brief survey
Creators: name: Sousa, Sónia
Publisher: name: Povos e Culturas
Year: 2010

description: The purpose of this paper is to provide a survey of the major theories of regional economic development that have guided the strategies and programs of regional economic development put in place over the last decades. The goal of this survey is fourfold. The first is to identify the major features of each theory. The second is to highlight similarities and contrasts among them. The third is to assess their major strengths and weaknesses with a view to underline the regional context where such theories can provide a better framework for regional analysis. The fourth is to discuss the factors missing in the mainstream theories of regional development that recent empirical evidence has demonstrated to play a crucial role in regional development in an era of economic globalization. Among them, and of particular relevance for regions located in developed economies, are: institutional framework, local innovative milieu and technological competitiveness, and local entrepreneurial capacity.

description: Unconventional emissions from exciton and trion in monolayer WS2 are studied by photoexcitation. Excited by 532nm laser beam, the carrier species in the monolayer WS2 are affected by the excess electrons escaping from photoionization of donor impurity, the concentration of which varies with different locations of the sample. Simply increasing the excitation power at room temperature, the excess electron and thus the intensity ratio of excited trion and exciton can be continuously tuned over a large range from 0.1 to 7.7. Furthermore, this intensity ratio can also be manipulated by varying temperature. However, in this way the resonance energy of the exciton and trion show red-shifts with increasing temperature due to electron-phonon coupling. The binding energy of the trion is determined to be ~23meV and independent to temperature, indicating strong Coulomb interaction of carriers in such 2D materials.

description: The existence of global-in-time weak solutions to reaction-cross-diffusion systems for an arbitrary number of competing population species is proved. The equations can be derived from an on-lattice random-walk model with general transition rates. In the case of linear transition rates, it extends the two-species population model of Shigesada, Kawasaki, and Teramoto. The equations are considered in a bounded domain with homogeneous Neumann boundary conditions. The existence proof is based on a refined entropy method and a new approximation scheme. Global existence follows under a detailed balance or weak cross-diffusion condition. The detailed balance condition is related to the symmetry of the mobility matrix, which mirrors Onsager's principle in thermodynamics. Under detailed balance (and without reaction), the entropy is nonincreasing in time, but counter-examples show that the entropy may increase initially if detailed balance does not hold.
