description: Hygroscopic growth models are currently of interest as aids for targeting the deposition of inhaled drug particles in preferred areas of the lung that will maximize their pharmaceutical effect. Mathematical models derived to estimate hygroscopic growth over time have been previously developed but have not been thoroughly validated. For this study, model validation involved a comparison of modeled values to measured values when the growing droplet had reached equilibrium. A second validation process utilized a novel system to measure the growth of a droplet on a microscope coverslip relative to modeled values when the droplet is undergoing the initial rapid growth phase. Various methods currently used to estimate the water activity of the growing droplet, which influences the droplet growth rate, were also compared. Results indicated that a form of the hygroscopic growth model that utilizes coupled-differential equations to estimate droplet diameter and temperature over time was valid throughout droplet growth until it reached its equilibrium size. Accuracy was enhanced with the use of a polynomial expression to estimate water activity relative to the use of a simplified estimate of water activity based on Raoult’s Law. Model accuracy was also improved when constraining the film of salt solution surrounding the dissolving salt core at saturation. Copyright © 2020 American Association for Aerosol Research

description: A new class of domain wall fermions is defined that interpolates between Shamir's and Boriçi's form without increasing the number of Dirac applications per CG iteration. This class represents a full (real) Möbius transformation of the Wilson kernel. Simulations on quenched Wilson lattices with $β= 6.0$ show that the number of lattice sites ($L_s$) in the fifth dimension can be reduced by a factor of 2 or more at fixed value of chiral symmetry violations measured by the residual mass ($m_{res}$).

description: Image ordinal estimation is to predict the ordinal label of a given image, which can be categorized as an ordinal regression problem. Recent methods formulate an ordinal regression problem as a series of binary classification problems. Such methods cannot ensure that the global ordinal relationship is preserved since the relationships among different binary classifiers are neglected. We propose a novel ordinal regression approach, termed Convolutional Ordinal Regression Forest or CORF, for image ordinal estimation, which can integrate ordinal regression and differentiable decision trees with a convolutional neural network for obtaining precise and stable global ordinal relationships. The advantages of the proposed CORF are twofold. First, instead of learning a series of binary classifiers \emph{independently}, the proposed method aims at learning an ordinal distribution for ordinal regression by optimizing those binary classifiers \emph{simultaneously}. Second, the differentiable decision trees in the proposed CORF can be trained together with the ordinal distribution in an end-to-end manner. The effectiveness of the proposed CORF is verified on two image ordinal estimation tasks, i.e. facial age estimation and image aesthetic assessment, showing significant improvements and better stability over the state-of-the-art ordinal regression methods.

Se utilizaron los datos disponibles en la FAO que fueron organizados en un panel de datos y se aplicó el análisis envolvente de datos con la herramienta de los índices de Malmquist, se agregó el enfoque de eciencia técnica ambiental, se consideró un modelo con tres componentes: productivo, ambiental y social. Así también, se indagó sobre la incidencia de actividad geomagnética solar planetaria sobre la productividad de las biorenerias. Los resultados se evaluaron considerando la actividad solar y omitiéndola, los primeros evidencian que solo los países Belice, El salvador (11 %), Nicaragua (4 %) y Cuba (3%) muestran un crecimiento promedio en productividad, al contrario Costa Rica, Guatemala, Honduras y Panamá presentaron un decrecimiento en productividad. El cambio de la PTF se explicó por el desarrollo tecnológico de los ingenios más que por la eciencia técnica de la mano de obra. Además, se concluye que la productividad de la bioeconomía tiene cierta relación con la actividad geomagnética planetaria y por consiguiente se debe tener en cuenta la relación entre la productividad de las biorenerías y la tasa de crecimiento poblacional. Es importante que los inversionista de los ingenios azucaremos consideren estas evidencias dado que conociendo las variaciones de la actividad solar pueden reducir costos no invirtiendo en economía de escala cuando la actividad solar proyecte una tendencia decreciente.

description: Atmospheric Aerosols affect Earth’s climate directly by scattering and absorbing solar radiation. In order to study the optical properties of aerosols, we developed a broadband cavity-enhanced spectrometer that uses a supercontinuum laser source and a compact spectrometer, to measure simultaneously the extinction coefficient of aerosols over a broad wavelength region from 420 to 540 nm. The system employs a dual cavity approach with a reference and a sample cavity, accounting for changes in gases background and for laser spectral and intensity fluctuations. We tested the system with aerosolized salt particles and polystyrene latex spheres. We performed calculations using Mie theory and found good agreement with the measured extinction. We also found that the extinction coefficient of non-absorbing aerosol favorably compares with the scattering coefficient measured by a nephelometer. Finally, we generated soot particles and found an extinction Ångström exponent in good agreement with values reported in the literature. Wavelength dependent detection limits (1σ) for the instrument at 5 nm wavelength resolution and for an integration time of ∼10 min were found to be in the range ∼5 Mm−1 to 13 Mm−1. The broadband dual-cavity extinction spectrometer is simple and robust and might be particularly useful for laboratory measurements of the extinction coefficient of brown carbon aerosol. The laboratory tests suggest that the prototype is promising for future developments of a field-deployable instrument. Copyright © 2020 American Association for Aerosol Research

description: Machine Learning (ML) has increased its role, becoming essential in several industries. However, questions around training data lineage, such as "where has the dataset used to train this model come from?"; the introduction of several new data protection legislation; and, the need for data governance requirements, have hindered the adoption of ML models in the real world. In this paper, we discuss how data lineage can be leveraged to benefit the ML lifecycle to build ML models to discover sweet-spots for shale oil and gas production, a major application in the Oil and Gas O&G Industry.

description: Recently, the KOTO experiment reported their new preliminary result of searching for the decay $K_L\toπ^0ν\barν$. Three candidate events were observed in the signal region, which exceed significantly the expectation based on the standard model. On the other hand, the new NA62 and previous BNL-E949 experiments yielded a consistent result and confirmed the standard model prediction in the charged meson decay $K^+\toπ^+ν\barν$. Furthermore, the two decays are bound by a well-motivated relation from an analysis of isospin symmetry that is hard to break by the new physics of heavy particles. In this work, we study the issue by a systematic effective field theory approach with three of the simplest scenarios, in which the $K_L$ may decay into a new light neutral particle $X$, i.e., $K_L\toπ^0X$, $K_L\to γγX$, or $K_L\toπ^0XX$. We assess the feasibility of the scenarios by simulations and by incorporating constraints coming from NA62 and other relevant experiments. Our main conclusion is that the scenario $K\toπXX$ for a long lived scalar $X$ seems more credible than the other two when combining distributions and other experimental constraints while the region below the KOTO's blind box provides a good detection environment to search for all three scenarios for a relatively heavy $X$.

title: From Knowledge to Invention: Exploring User Innovation in Irish Agriculture
Creators: name: O'Flynn, Patricia
Publisher: name: The Open University
Year: 2017

description: Improvements in European agriculture are framed in the literature as arising from an Agricultural Knowledge and Innovation System with innovations provided by others for farmers to adopt. The motivators for farmers who invent useful products for themselves, without outside involvement, are not well understood in such developed countries. These inventions, often shared with other farmers rather than introduced to the market, arise from a process of user innovation (von Hippel, 2005). This thesis examines Irish farmers’ motivators in the creation and subsequent sharing or commercialisation of farming artefacts. Their motivators are conceptualised from a sociological perspective, using Bourdieu’s theory of capitals (1986). Employing a multi-perspective research design, methods include a content analysis of 210 inventions, semi-structured interviews with key informants from innovation support organisations, and in-depth interviews with farmer-inventors. The findings indicate that most farmer-inventors get great personal satisfaction from problem-solving and, being generally without higher education, use their tacit knowledge to create inventions that increase efficiency as a means to improve family farm viability. Despite efficiency usually indicating skilful farming, Irish farmer-inventors are frequently derided by other farmers who deem their inventing to be culturally inappropriate. Farmer-inventors with entrepreneurial intentions, willing to withstand such hostility, face financial and temporal constraints, while the help offered by innovation support organisations is often inadequate. As a result, some inventions with commercial potential may never reach the market. Farmer-inventors who share their knowledge and inventions in social learning networks, similar to communities of practice, accrue social capital that leads to the emergence of a shared farmer-inventor identity. This thesis contributes to knowledge about user innovation in developed country agriculture by offering deeper understandings of farmer-inventors’ social, cultural, and economic processes. It proposes farmers to be an underappreciated source of knowledge and inventions, which offer low cost farm-level solutions to support family farm resilience.

Molecular evolutionary studies on the chlorarachniophyte : Bigelowiella natans
Creators: name: Rogers, Matthew Brian
Publisher: name: University of British Columbia
Year: 2011

description: Chlorarachniophytes are marine cercozoan amoeboflagellates with plastids derived from a secondary endosymbiotic event involving a green alga. The retention of a vestigial eukaryotic nucleus, or 'nucleomorph' in the plastid of chlorarachniophytes makes chlorarachniophytes ideal organisms for the study of secondary endosymbiosis. Among chlorarachniophytes, the majority of sequence data are from a single species, Bigelowiella natans. Thousands of expressed sequence tags and a complete nucleomorph and chloroplast genome from Bigelowiella natans provide a detailed picture of genes encoding proteins with function in the plastid of chlorarachniophytes. The phylogeny of three plastid-targeted Calvin cycle enzymes with complicated distributions and multiple recompatmentalisation events are described. These three enzymes are also the only known Calvin cycle enzymes in B. natans that show any evidence of having been acquired through endosymbiotic gene transfer. Previous studies have detailed the contribution of lateral gene transfer to the plastid function of B. natans. Several specific examples of these events are expanded on and discussed. Plastid-targeting peptides from published sequences are characterized and a heterologous targeting experiment in to the apicoplast of Toxoplasma gondii is described. The complete plastid genome of Bigelowiella natans has been sequenced. This plastid genome appears to be the smallest among all known photosynthetic plastid genomes, though it nevertheless retains most of the photosynthesis related genes present in chlorophytes. Phylogenetic analysis of concatenated chloroplast protein coding genes indicates that the endosymbiont of B. natans may be a derived green algae, and argues strongly against a single origin of chlorarachniophyte and euglenids plastids predicted by the cabozoa hypothesis.
Investigating the effect of in-plane spin directions for Precessing BBH systems

description: Morphology of coalescing BBH waveforms are affected by its spins. Waveform models built for inference of source parameters have several in-built approximations. In current precessing IMRPhenom and SEOBNR waveform models, systems with the same spin magnitude but varying orientation of spins projected on the orbital plane are effectively mapped to the same system (bar an overall phase change) and the asymmetry due to precession between the $+m$ and $-m$ modes is not modelled. In this study, we investigate the validity of these approximations by generating numerical relativity (NR) simulations of single-spin NR systems with varying in-plane spin directions (including several superkick configurations) and provide an estimate of the SNR at which the effect of varying in-plane spin directions would be measurable. This is done computing the match between these waveforms and using these match values to estimate the distinguishability SNR. We also use NR waveforms with different spin magnitudes to compare the measurability of spin magnitude vs. in-plane spin direction. We find that the in-plane spin direction could be measurable at SNRs accessible by current generation detectors, with the distinguishability SNR of varying in-plane spins comparable to or lower than varying the in-plane spin magnitude. We then remove the mode-asymmetry content from the waveforms and find that, i) removing mode-asymmetry increases the SNR at which in-plane spin direction can be measured and ii) not modelling mode-asymmetry will lead to measurement biases. The SNRs that we see at which the in-plane spins would be measurable and at which mode-asymmetric content impacts the measurements are the SNRs at which precession would be measurable, and we therefore conclude that modelling in-plane spin direction and mode-asymmetry effects is necessary for unbiassed measurements of precession.

description: Il primo articolo pubblicato di Franco Modigliani è divenuto uno dei testi base della moderna economia keynesiana. In esso ha formalizzato il modello (o almeno un modello) implicito nella Teoria Generale. Modigliani sosteneva che le caratteristiche conclusioni keynesiane poggiano fondamentalmente sulla (realistica) rigidità dei salari nominali. In particolare, ha mostrato che se i salari e i prezzi fossero flessibili, la teoria della preferenza di liquidità della moneta non potrebbe generare persistente disoccupazione involontaria, ma se i salari fossero rigidi, anche la teoria della quantità della moneta potrebbe farlo. Sessant’anni più tardi Modigliani è tornato a esporre il “vangelo keynesiano” e ha proposto essenzialmente la medesima interpretazione. Questo articolo riconsidera e discute questo approccio alla macroeconomia, con alcuni riferimenti alle sue implicazioni per la politica economica. The first article published by Franco Modigliani has become one of the basic texts of the modern Keynesian economics. It formalized the model (or at least one model) implicit in the General Theory. Modigliani argued that the characteristics Keynesian conclusions are based primarily on the (realistic) rigidity of nominal wages. In particular, it showed that if wages and prices were flexible, the theory of liquidity preference of money could not generate persistent involuntary unemployment, but if wages were rigid, the theory of the amount of money could do it. Sixty years later Modigliani returned to expose the "Keynesian gospel" and proposed essentially the same interpretation. This article reconsiders and discusses this approach to macroeconomics, with some reference to its implications for economic policy.

title: HSP70 as a Target for Correction of Wilson Disease Causing ATP7B Mutants
Creators: name: Concilli, Mafalda
Publisher: name: The Open University
Year: 2017

description: Copper (Cu) is an essential micronutrient, which operates as a cofactor of enzymes regulating a wide range of critical physiological processes. However, Cu overload compromises the redox balance in cells and tissues causing serious toxicity. Removal of excess Cu from the body is driven be Cu-transporting ATPase ATP7B, which sequesters the potentially toxic metal and mediates its excretion into the bile. Mutations in the ATP7B result in Wilson disease (WD) that is caused by the toxic accumulation of Cu in the liver due to the loss of ATP7B function. The most frequent ATP7B mutant, H1069Q, still preserves a significant Cu-transporting activity, but undergoes retention and degradation in the endoplasmic reticulum (ER). Thus, rescue of ATP7B-H1069Q from the ER is expected to recover mutant function and, hence, would be beneficial for a large group of WD patients. Unfortunately, specific targets as well as safe drugs for correction of ATP7B-H1069Q mutant remain to be uncovered. Comparing interactomes of WT and H1069Q variants of ATP7B, I found HSP70 as a specific mutant interactor that regulates ER retention and degradation of ATP7B-H1069Q. HSP70 suppression (with either RNAi or allosteric inhibitor) improved stability of the mutant and facilitated its export from the ER to the Golgi and post-Golgi copper excretion sites. These findings prompted me to look for a safe way to inhibit HSP70 and rescue the ATP7B mutant. To this end several bioinformatics tools were employed to search for FDA-approved drugs that modulate HSP70 expression or exhibit structural similarity to HSP70 inhibitors. As a result, Domperidone and glucocorticoid receptor agonists were identified and validated as effective correctors of ATP7B mutant. In summary, my findings suggest a key role for HSP70 in proteostasis of ATP7B-H1069Q and revealed FDA-approved compounds as safe drugs for ATP7B mutant correction and, thus, for the normalization of Cu homeostasis in Wilson disease patients.

description: Modigliani ebbe percezione dell’importanza della Teoria Generale di Keynes ancor prima di incominciare a studiare economia. Dopo essere diventato economista di professione, grazie alla sua ricerca, sia teorica che applicata, il suo insegnamento, le sue raccomandazioni a combattere la disoccupazione di massa, Modigliani divenne noto a livello mondiale come uno dei più grandi economisti keynesiani. Eppure vi sono molte componenti essenziali della Teoria Generale di Keynes che nei lavori di Modigliani non si trovano. In questa lezione si mostra come il suo sforzo – per usare una sua espressione – di “digerire” le idee innovative di Keynes nella più tradizionale teoria walrasiana porti alla perdita delle idee più genuinamente rivoluzionarie di Keynes. L’autore sostiene – riferendosi anche ad alcuni ricordi personali – che la convinzione di Keynes della necessità di costruire una nuova “teoria monetaria della produzione” rimane rilevante oggi quanto lo era all’epoca in cui venne proposta. Più che cercare di “digerire” la rivoluzione keynesiana, dovremmo cercare di portarla pienamente a compimento. Modigliani was perceived importance of the General Theory of Keynes even before begin to study economics. After becoming an economist by profession, thanks to his research, both theoretical and applied, its teaching, its recommendations to combat mass unemployment, Modigliani became known worldwide as one of the greatest Keynesian economists. Yet there are many essential elements of the General Theory of Keynes that in the works of Modigliani are not. In this lesson we show how his effort - to use his own expression - to "digest" the innovative ideas of Keynes in the more traditional Walrasian theory lead to the loss of more genuinely revolutionary ideas of Keynes. The author claims - referring to some personal memories - that the belief of Keynes to the need to build a new "monetary theory of production" remains as relevant today as it was at the time it was proposed. More than trying to "digest" the Keynesian revolution, we should try to bring it fully to fruition.

description: Conobbi Franco Modigliani nel 1948. Avevamo interessi comuni in tre campi della teoria economica – Keynes e la disoccupazione, i rapporti fra meccanismi monetari e quelli reali, le forme di mercato e la formazione dei prezzi; in altri due campi, ampiamente esplorati da Modigliani, l’interesse comune era minore – mi riferisco ai problemi del risparmio e del ciclo vitale. Comune era anche l’amore per le verifiche empiriche e, su un piano diverso, sull’impegno civile. Intellettualmente ci siamo incontrati sulla questione della formazione dei prezzi in regime di oligopolio, che può essere visto, nelle sue diverse configurazioni, come la forma di mercato più frequente nell’economia moderna. Modigliani ha incorporato la formula della formazione e delle variazioni dei prezzi in oligopolio in due modelli econometrici, il primo elaborato negli Stati Uniti, il secondo in Italia. Negli ultimi anni Modigliani si fece promotore di un “Manifesto contro la disoccupazione nell’Unione Europea”, al quale collaborarono sei economisti europei (io ero fra questi) e che ebbe poi l’adesione di un gran numero di economisti di tutto il mondo. Nel Manifesto giocano un ruolo di rilievo la funzione degli investimenti, concepita da Modigliani e da me in modi diversi ma complementari e il modello delle variazioni dei prezzi, visto con riferimento al problema dell’inflazione. I met Franco Modigliani in 1948. We had common interests in three fields of economics - Keynes and unemployment, the relationship between monetary mechanisms and the real, forms of market and price formation, in two other fields, widely explored by Modigliani, the common interest was less - I am referring to the problems of saving and the life cycle. Was also common love for empirical tests and, on a different level, on civic engagement. Intellectually we met on the issue of price formation in an oligopoly, which can be seen, in its various forms, such as the shape of the market more frequently in the modern economy. Modigliani incorporated the formula of training and changes in prices in oligopoly in two econometric models, the first developed in the United States, the second in Italy. In recent years, Modigliani became the promoter of a "Manifesto against unemployment in the European Union", which collaborated in six European economists (I was among them) and then had the accession of a large number of economists from around the world. In the Manifesto play an important role the investment function, designed by Modigliani and me in different but complementary ways, and the pattern of changes in prices, given with reference to the problem of inflation.

description: Hygroscopic growth models are currently of interest as aids for targeting the deposition of inhaled drug particles in preferred areas of the lung that will maximize their pharmaceutical effect. Mathematical models derived to estimate hygroscopic growth over time have been previously developed but have not been thoroughly validated. For this study, model validation involved a comparison of modeled values to measured values when the growing droplet had reached equilibrium. A second validation process utilized a novel system to measure the growth of a droplet on a microscope coverslip relative to modeled values when the droplet is undergoing the initial rapid growth phase. Various methods currently used to estimate the water activity of the growing droplet, which influences the droplet growth rate, were also compared. Results indicated that a form of the hygroscopic growth model that utilizes coupled-differential equations to estimate droplet diameter and temperature over time was valid throughout droplet growth until it reached its equilibrium size. Accuracy was enhanced with the use of a polynomial expression to estimate water activity relative to the use of a simplified estimate of water activity based on Raoult’s Law. Model accuracy was also improved when constraining the film of salt solution surrounding the dissolving salt core at saturation.

description: The article offers to describe and analyse the economic motivations for creating and operating observatories of agricultural practices. An observatory is a unit provided with technical, financial and human means as well as information and data, and which uses them to produce information and knowledge for both private and public users. The main obstacle in creating an observatory is its initial cost, as its activity is profitable only in the medium to long term. A second obstacle is maintaining cooperation between all the involved parties since investments and benefits are not equally shared among them. Finally, public policies also give incentives to create and maintain observatories. Performance-based contracts offered to farmers tend to encourage them to increase their knowledge regarding the environmental impacts of agricultural practices. Contracts based on agricultural practices rather than environmental impacts have the opposite effect: the government, bearing all the costs related to uncertainties as to the environmental outcomes, is not willing to offer high payments to the farmers, thus discouraged. We argue that innovative agri-environmental policies, environmentally-efficient and balanced as to responsibilities, can be offered to farmers if they are negotiated by all parties within observatories.

description: L’articolo analizza retrospettivamente dopo sette anni l’impatto che la pubblicazione del “Manifesto contro la disoccupazione nell’UE” ha avuto sulle politiche economiche attivate nei vari paesi europei. Dal lato dell’offerta, si prende atto che molti suggerimenti del “Manifesto” sono stati messi in pratica, tra cui risultano particolarmente significative le riforme del mercato del lavoro approvate di recente in Italia, Germania e Francia. Tali riforme hanno introdotto più flessibilità nei contratti di lavoro, che ha favorito l’aumento dell’occupazione e la discesa del tasso di disoccupazione in tutti i paesi. Non altrettanto soddisfacenti, invece, sono stati i risultati conseguiti nelle politiche di gestione della domanda aggregata. Alle politiche fiscali restrittive imposte dal rispetto dei parametri di Maastricht, infatti, ha fatto riscontro una politica monetaria della BCE altrettanto restrittiva, che ha fatto apprezzare l’euro e fatto perdere competitività alle merci europee nel mercato internazionale. Altrettanto deludenti sono giudicate le politiche regionali di sviluppo, per le quali si suggerisce un uso più appropriato della politica d’incentivazione fiscale per attirare nuovi investimenti nelle aree sottosviluppate. The article analyzes retrospectively after seven years the impact that the publication of the "Manifesto against unemployment in the EU" has had on economic policies enabled in the various European countries. On the supply side, it is recognized that many suggestions of the "Manifesto" were put into practice, such as are particularly significant reforms of the labor market recently adopted in Italy, Germany and France. Such reforms have introduced more flexibility in contracts of employment, which has favored the increase in employment and the decline in unemployment in all countries. Not so satisfactory, however, were the results achieved in the policies of aggregate demand management. The restrictive fiscal policies imposed by the requirements of the Maastricht criteria, in fact, has been matched by equally restrictive monetary policy of the ECB, which has made appreciate the euro and made ​​European goods less competitive in the international market. Equally disappointing are judged regional development policies, for which we suggest a more appropriate use of the policy of tax incentives to attract new investment in underdeveloped areas.

description: Two approaches are presented to coupling explicit Goldstone modes to $N_f$ flavors of massless quarks preserving exact $SU(N_f) \times SU(N_f)$ chiral symmetry on the lattice. The first approach is a generalization a chiral extension to QCD (aka XQCD) proposed by Brower, Shen and Tan consistent with the Ginsparg-Wilson relation. The second approach based on the Callan,Coleman, Wess and Zumino coset construction has a real determinant atzero quark axial coupling, $g_A = 0$.

Dalla teoria alla pratica nei modelli macroeconomici: l’eclettismo post-keynesiano (From theory to practice in macroeconomic models: the eclectic post-Keynesian)

description: Questo saggio riesamina e discute il contributo di Franco Modigliani alla costruzione di modelli macroeconomici utilizzati per la previsione e per l’elaborazione delle politiche economiche. Come ha osservato Paul Samuelson, il lavoro teorico svolto da Modigliani è stato fondamentale per lo sviluppo del quadro d’insieme entro il quale è maturato l’“eclettismo post-keynesiano” della seconda metà del ventesimo secolo. Nel passaggio dalla teoria alla pratica vengono considerati due aspetti del lavoro di Modigliani: 1) l’impostazione sistemica che si incentra sulla relazione tra il breve e il lungo periodo; 2) il particolare riferimento al meccanismo di trasmissione della politica monetaria nell’utilizzo del modello macroeconomico per le politiche di stabilizzazione economica. Si discute, infine, brevemente ciò che oggi resta di questo contributo, anche in relazione ad alcune recenti proposte sulla costruzione di modelli macroeconomici. This paper re-examines and discusses the contribution of Franco Modigliani in the construction of macroeconomic models used for prediction and for the development of economic policies. As noted by Paul Samuelson, the theoretical work done by Modigliani was instrumental in the development of the overall framework within which it is matured the " post-Keynesian eclecticism " in the second half of the twentieth century. In the transition from theory to practice are considered two aspects of the work of Modigliani: 1) the systemic approach that focuses on the relationship between the short and long term, and 2) the specific reference to the transmission mechanism of monetary policy in the use of macroeconomic model for policies of economic stabilization. Discuss, finally, briefly what remains today of this contribution, also in connection with some recent proposals on the construction of macroeconomic models.

description: The scalar radius of the pion plays an important role in CHPT, because it is related to one of the basic effective coupling constants, viz. the one which controls the quark mass dependence of F_pi at one loop. In a recent paper, Yndurain derives a {\it robust lower bound} for this radius, which disagrees with earlier determinations. We show that such a bound does not exist: the "derivation" relies on an incorrect claim. Moreover, we discuss the physics of the form factors associated with the operators \ubar u, \dbar d and \sbar s and show that their structure in the vicinity of the K \Kbar threshold is quite different. Finally, we draw attention to the fact that the new data on the slope of the scalar K_l3 form factor confirm a recent, remarkably sharp theoretical prediction.

description: Despite previous extensive analysis of open quantum systems described by the Lindblad equation, it is unclear whether correlated topological states, such as fractional quantum Hall states, are maintained even in the presence of the jump term. In this paper, we introduce the pseudo-spin Chern number of the Liouvillian which is computed by twisting the boundary conditions only for one of the subspaces of the doubled Hilbert space. The existence of such a topological invariant elucidates that the topological properties remain unchanged even in the presence of the jump term which does not close the gap of the effective non-Hermitian Hamiltonian (obtained by neglecting the jump term). In other words, the topological properties are encoded into an effective non-Hermitian Hamiltonian rather than the full Liouvillian. This is particularly useful when the jump term can be written as a strictly block-upper (-lower) triangular matrix in the doubled Hilbert space, in which case the presence or absence of the jump term does not affect the spectrum of the Liouvillian. With the pseudo-spin Chern number, we address the characterization of fractional quantum Hall states with two-body loss but without gain, elucidating that the topology of the non-Hermitian fractional quantum Hall states is preserved even in the presence of the jump term. This numerical result also supports the use of the non-Hermitian Hamiltonian which significantly reduces the numerical cost. Similar topological invariants can be extended to treat correlated topological states for other spatial dimensions and symmetry (e.g., one-dimensional open quantum systems with inversion symmetry), indicating the high versatility of our approach.
