description: Using the measured spectrum shape for $B \to π\ell ν$, the rate for $B^+ \to π^+ π^0$, information on the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $|V_{ub}|$, and theoretical inputs from factorization and lattice gauge theory, we obtain an improved estimate of the ``tree'' contribution to $B^0 \to π^+ π^-$. We find the branching ratio $\b(B^0 \to π^+ π^-)|_{\rm tree} = (5.25^{+1.67}_{-0.50}) \times 10^{-6}$, to be compared with the experimental value $\b(B^0 \to π^+ π^-) = (4.55 \pm 0.44) \times 10^{-6}$. The fit implies $|V_{ub}| = (3.62 \pm 0.34) \times 10^{-3}$. Implications for tree-penguin interference in $B^0 \to π^+ π^-$ and for other charmless $B$ decays are discussed.

description: We propose a new quantum dynamics method called the effective potential analytic continuation (EPAC) to calculate the real time quantum correlation functions at finite temperature. The method is based on the effective action formalism which includes the standard effective potential. The basic notions of the EPAC are presented for a one-dimensional double well system in comparison with the centroid molecular dynamics (CMD) and the exact real time quantum correlation function. It is shown that both the EPAC and the CMD well reproduce the exact short time behavior, while at longer time their results deviate from the exact one. The CMD correlation function damps rapidly with time because of ensemble dephasing. The EPAC correlation function, however, can reproduce the long time oscillation inherent in the quantum double well systems. It is also shown that the EPAC correlation function can be improved toward the exact correlation function by means of the higher order derivative expansion of the effective action.

description: The presence of additional compact dimensions in cosmological models is studied in the context of modified teleparallel theories of gravity. We focus the analysis on eleven dimensional spacetimes, where the seven dimensional extra dimensions are compactified. In particular, and due to the importance that global vector fields play within the conceptual body of teleparallel modified gravity models, we consider the additional dimensions to be products of parallelizable spheres. The global vector fields characterizing the different topologies are obtained, as well as the equations of motion associated to them. Using global dynamical system techniques, we discuss some physical consequences arising because of the existence of the extra dimensions. In particular, the possibility of having an early inflationary epoch driven by the presence of extra dimensions without other matter sources is discussed.

description: The James Webb Space Telescope (JWST) is expected to revolutionize our understanding of Jovian worlds over the coming decade. However, as we push towards characterizing cooler, smaller, "terrestrial-like" planets, dedicated next-generation facilities will be required to tease out the small spectral signatures indicative of biological activity. Here, we evaluate the feasibility of determining atmospheric properties, from near-to-mid-infrared transmission spectra, of transiting temperate terrestrial M-dwarf companions. Specifically, we utilize atmospheric retrievals to explore the trade space between spectral resolution, wavelength coverage, and signal-to-noise on our ability to both detect molecular species and constrain their abundances. We find that increasing spectral resolution beyond R=100 for near-infrared wavelengths, shorter than 5$μ$m, proves to reduce the degeneracy between spectral features of different molecules and thus greatly benefits the abundance constraints. However, this benefit is greatly diminished beyond 5$μ$m as any overlap between broad features in the mid-infrared does not deconvolve with higher resolutions. Additionally, our findings revealed that the inclusion of features beyond 11$μ$m did not meaningfully improve the detection significance nor abundance constraints results. We conclude that an instrument with continuous wavelength coverage from $\sim$2-11$μ$m, spectral resolution of R$\simeq$50-300, and a 25m$^2$ collecting area, would be capable of detecting H$_2$O, CO$_2$, CH$_4$, O$_3$, and N$_2$O in the atmosphere of an Earth-analog transiting a M-dwarf (mag$_{K}=8.0$) within 50 transits, and obtain better than an order-of-magnitude constraint on each of their abundances.

description: This paper investigates the impact of subsidies from the common agricultural policy on the total factor productivity of farms in the EU. We employ a structural, semi-parametric estimation algorithm, directly incorporating the effect of subsidies into a model of unobserved productivity. We empirically study the effects using samples from the Farm Accountancy Data Network for EU-15 countries. Our main findings are clear: subsidies had a negative impact on farm productivity in the period before the decoupling reform was implemented; after decoupling the effect of subsidies on productivity was more nuanced, as in several countries it turned positive.
Photoevaporation of Minihalos during Reionization

description: We present the first gas dynamical simulations of the photoevaporation of cosmological minihalos overtaken by the ionization fronts which swept through the IGM during reionization in a LCDM universe, including the effects of radiative transfer. We demonstrate the phenomenon of I-front trapping inside minihalos, in which the weak, R-type fronts which traveled supersonically across the IGM decelerated when they encountered the dense, neutral gas inside minihalos, becoming D-type I-fronts, preceded by shock waves. For a minihalo with virial temperature T_vir < 10,000 K, the I-front gradually burned its way through the minihalo which trapped it, removing all of its baryonic gas by causing a supersonic, evaporative wind to blow backwards into the IGM, away from the exposed layers of minihalo gas just behind the advancing I-front. Such hitherto neglected feedback effects were widespread during reionization. N-body simulations and analytical estimates of halo formation suggest that sub-kpc minihalos such as these, with T_vir < 10,000 K, were so common as to dominate the absorption of ionizing photons. This means that previous estimates of the number of ionizing photons per H atom required to complete reionization which neglected this effect may be too low. Regardless of their effect on the progress of reionization, however, the minihalos were so abundant that random lines of sight thru the high-z universe should encounter many of them, which suggests that it may be possible to observe the processes described here in the absorption spectra of distant sources.

description: O Brasil alcançou em 2004 a liderança nas exportações de carne de frango, com um volume de 2,4 milhões de toneladas, ultrapassando os Estados Unidos. Essa liderança foi obtida por meio da somatória de fatores que levaram as empresas brasileiras a melhorarem sua competitividade, frente aos concorrentes internacionais. Se a influenza aviária permitiu que o país alcançasse mercados, que até então eram atendidos pelos países afetados pela doença, a manutenção de vendas a esses mercados e o incremento de vendas para outros países, deveu-se a muitas variáveis. É verdade sim, que o Brasil possui vantagens competitivas na dotação de recursos naturais e na disponibilidade de mão-deobra, o qual lhe permite obter custos de produção mais baixos. Entretanto, muitos outros fatores que explicam o menor custo – como a própria economia de escala na produção – são mantidos também pelos seus concorrentes. O que faz do país o maior exportador mundial, com crescimento significativo em termos de produção, consumo e comércio internacional, nos últimos dez anos, são inclusive, as ações estratégicas das empresas, que asseguram condições de confiabilidade em relação ao cliente externo, com atendimento de especificações peculiares, manutenção do padrão de qualidade, dentre outros fatores.

Additional information about this Adis Drug Review can be found here AbstractThe oral phosphodiesterase 4 inhibitor apremilast (Otezla®) is indicated for the treatment of oral ulcers associated with Behçet’s disease in some countries, including the USA (where it is the first agent approved for the disease) and Japan. In phase 2 and 3 trials in adults with this chronic and debilitating disorder, 12 weeks of treatment with apremilast 30 mg twice daily reduced the number and pain of oral ulcers and disease activity relative to placebo, with these clinical benefits being accompanied by improvements in health-related quality of life (HR-QOL). Benefits of apremilast were seen regardless of baseline patient/disease characteristics and in Japanese patients, and were sustained over up to 64 weeks of treatment. Apremilast was generally well tolerated, with gastrointestinal adverse events being among the most common tolerability issues. Emerging real-world data also support the drug’s use in this setting. Thus, for patients with oral ulcers associated with Behçet’s disease, apremilast provides an effective and generally well tolerated approved treatment option.

description: Two coupled semiconductor nanolasers exhibit a mode switching transition, theoretically characterized by limit cycle $-$or mode-beating$-$ oscillations. Their decay rate is vanishingly small in the thermodynamic limit, i.e. when the spontaneous emission noise $β$-factor tends to zero. We provide experimental evidence of mesoscopic limit cycles $-$with $\sim 10^3$ intracavity photons$-$ through photon statistics measurements. We first show that the order parameter quantifying the limit cycle amplitude can be reconstructed from the mode intensity statistics. As a main result we observe a maximum of the averaged amplitude at the mode switching, accounting for limit cycle oscillations. We finally relate this maximum to a dip of mode cross-correlations, reaching a minimum of $g_{ij}^{(2)}=2/3$, which we show to be a mesoscopic limit. Coupled nanolasers are thus an appealing testbed for the investigation of spontaneous breaking of time-translation symmetry in presence of strong quantum fluctuations.

description: A aplicação incorreta dos agrotóxicos, freqüentemente, apresenta graves riscos para o homem. A contaminação do ar, das águas e do solo é freqüente. São inúmeras as conseqüências no meio ambiente e na saúde humana do uso intensivo dos agrotóxicos, tendo em vista o impacto econômico negativo, com nítidas repercussões sociais. No presente artigo pretende-se analisar as características das lavouras de tomate, no Estado do Rio de Janeiro, apontando os municípios que se destacam quanto à utilização de agrotóxicos. Foram utilizados os microdados do Censo Agropecuário, em 1995/1996, que trazem informações sobre os estabelecimentos agropecuários que cultivam tomate. Somando-se a isso, foi possível construir um indicador sintético, que avalia a qualidade de produção, levando em conta variáveis como produtividade, uso de agrotóxico, assistência técnica, irrigação, controle de pragas e doenças e conservação do solo. Os resultados sugerem que nem sempre alta produtividade esta associada à qualidade de produção, e que nenhum município do Estado apresentou ótima qualidade em produção. Por último, concluímos que é necessário avaliar conjuntamente a produtividade e alguns impactos sobre o meio ambiente e a saúde das populações, uma vez que a atividade agrícola convencional, que utiliza intensivamente os agrotóxicos, transfere alguns custos ambientais para toda sociedade.

description: Recently, Troyan et al (2019 arXiv:1908.01534) and Kong et al (2019 arXiv:1909.10482) extended near-room-temperature superconductors family by new yttrium superhydride polymorphs, YHn (n = 4,6,7,9), which exhibit superconducting transition temperatures in the range of Tc = 210-243 K at pressure of P = 160-255 GPa. In this paper, temperature dependent upper critical field data, Bc2(T), for highly-compressed mixture of YH4+YH6 phases (reported by Kong et al 2019 arXiv:1909.10482) is analysed to deduce the ratio of Tc to the Fermi temperature, Tf. Our analysis shows that in all considered scenarios the YH4+YH6 mixture has the ratio 0.01 < Tc/Tf < 0.04. As the result, YH4+YH6 falls in the unconventional superconductors band in the Uemura plot. It is also found that the characteristic temperature of the order parameter amplitude fluctuations, Tfluc, in the YH4+YH6 mixture is only several percent above observed Tc, and thus the superconducting transition in yttrium superhydride polymorphs is fundamentally limited by thermodynamics fluctuations.

description: After many years of debate, in 2005 Brazilian environmentalists, religious groups, scientists, farmers and seed companies reached an agreement on the rules for biotechnology research in general and of genetic modified crops in particular. While the debate at the two houses of congress was carried, Brazilian soybean growers have already adopted genetic modified soybean varieties since 1999 especially in the state of Rio Grande do Sul. Long lasting discussions in the congress offered no solution to the question of the legality of the adoption of GMO seeds particularly the cost saving technology owned by MONSANTO. Most farmers have taken the decision to buy uncertified seeds in the shadow market originated from Argentina creating a de facto situation where the illegal use of proprietary technology was predominant. Since Brazil recognizes property rights of plant varieties as well as of utility patents, in case of adoption the legal owner has the right to collect royalties. However how to harvest the rights if the transaction was carried in the shadow market? How to write contracts to bound transactions in the absence of law? The focus of this paper is the description of the institutional arrangement designed to collect royalties in a situation of weak property rights. The paper describes how a private solution has been designed, however at a higher transaction cost

Isso é bem evidenciado no agronegócio florestal na região Sul, com a presença dos Institutos de Pesquisa Mistos (IPMs), os quais prestam serviços diretamente para as empresas associadas. Também atuam neste tipo de atividade, os Institutos Públicos de Pesquisa (IPPs), os quais têm suas atividades de PD&I direcionadas ao atendimento das necessidades de uma clientela ampla e diversificada no meio rural. Com o objetivo de identificar as possíveis diferenças nos modelos de geração, difusão e transferência de tecnologia dos IPPs e IPMs e qual o modelo atualmente em uso por esses institutos é que o presente estudo foi idealizado e implementado. Apoiada em um referencial teórico sobre transferência de tecnologia, PD&I em colaboração e ação dos stakeholders, complementado pela noção do sistema nacional de inovação, foi utilizada a metodologia de estudo de casos para a realização da pesquisa. Os dados foram coletados junto aos principais IPPs e IPMs, atualmente em operação na região Sul. Os resultados alcançados demonstraram a existência de diferenças marcantes na postura desses institutos, principalmente, levando em conta a sua clientela, a postura mais competitiva que colaborativa, tanto entre os usuários das pesquisas como no relacionamento entre os próprios institutos de pesquisa. A análise conjunta do SNI e da ação dos stakeholders, permitiu concluir que, instituição importante desse sistema tem atuado mais de uma forma limitadora que facilitadora das ações dos IPPs e IPMs, principalmente nos aspectos regulatórios e fiscalizadores da atividade florestal, em detrimento de ações estimuladoras em prol do desenvolvimento econômico, social e do agronegócio florestal da região Sul, resultados que também levam a concluir a influência do SNI no direcionamento do modelo de pesquisa desses institutos mais para um modelo mercadológico que tecnológico.

description: Die aktuell besten Ansätze zur Disaggregation von Haushaltsenergiemessdaten, die von handelsüblichen Smart Meter erfasst werden, basieren auf künstlichen neuronalen Netzen, die mit einer Deep-Learning-Methodik erstellt sind. Die Leistungsfähigkeit dieser Ansätze objektiv zu vergleichen ist allerdings schwer, da die Ansätze oft auf unterschiedlichen Datensätzen evaluiert werden, Trainingsverfahren nicht ausführlich beschrieben sind und keine einheitlichen Testmetriken verwendet werden. Erst durch die Evaluation bekannter Ansätze basierend auf einem einheitlichen Aufbau für Disaggregationsexperimente wird in dieser Arbeit deutlich, dass die Praxistauglichkeit aller Ansätze insbesondere durch die geringe Anzahl unterschiedlicher Gerätemodelle im Trainingsdatensatz beschränkt ist. Um für einen festgelegten Trainingsdatensatz den Fehler bei der Gerätelastgangsschätzung dennoch zu verringern, fokussiert sich die vorliegende Arbeit auf das Problem, dass Ansätze oftmals eindeutig falsche und unplausible Gerätelastgänge ausgeben, die von realen Geräten nicht reproduziert werden können. Dazu werden zwei verschiedene neue Ansätze untersucht, die die Plausibilität der geschätzten Lastgänge sicherstellen sollen. Zur Erzeugung von plausiblen Gerätelastgängen werden unterschiedliche Teile eines Generative Adversarial Networks (GAN) verwendet. Ein dritter Ansatz entwirft ein bestehendes Netzmodell neu und kombiniert dieses mit der U-Net-Architektur durch das Hinzufügen von Querverbindungen zwischen Netzschichten. Dies soll helfen, Detailinformationen in den Lastgängen besser zu reproduzieren. Bei der Evaluation der eigenen Ansätze mit dem gleichen Experimentenaufbau werden bei dem zweiten Ansatz häufiger realisierbare Lastgänge ausgegeben. Dabei bleibt die Disaggregationsgenauigkeit auf dem gleichen Niveau. Durch einen weiteren Austausch der beim Modelltraining verwendeten Verlustfunktion wird erreicht, dass sich alle betrachteten Bewertungsmetriken im Mittel über alle Geräte verbessern. Zudem kann bei bestimmten Geräteklassen mit der im dritten Ansatz evaluierten U-Net-Architektur eine weitere Verbesserung der Bewertungsmetriken erzielt werden.

description: Solutions of the boundary-value problem for electromagnetic waves guided by a layer of a homogeneous and isotropic (metal or dielectric) material sandwiched between a structurally chiral material (SCM) and a periodically multi-layered isotropic dielectric (PMLID) material were numerically obtained and analyzed. If the sandwiched layer is sufficiently thick, the two bimaterial interfaces decouple from each other, and each interface may guide one or more electromagnetic surface waves (ESWs) by itself. Depending on the constitution of the two materials that partner to form an interface, the ESWs can be classified as surface-plasmon-polarition (SPP) waves, Tamm waves, Dyakonov-Tamm waves, or Uller-Zenneck waves. When the sandwiched layer is sufficiently thin, the ESWs for single bimaterial interfaces coalesce to form compound guided waves (CGWs). The phase speeds, propagation distances, and spatial profiles of the electromagnetic fields of CGWs are different from those of the ESWs. The energy of a CGW is distributed in both the SCM and the PMLID material, if the sandwiched layer is sufficiently thin. Some CGWs require the sandwiched layer to have a minimum thickness. Indeed, the coupling between the two faces of the sandwiched layer is affected by the ratio of the thickness of the sandwiched layer to the skin depth in that material and the rates at which the fields of the ESWs guided individually by the two interfaces decay away from their respective guiding interfaces.

description: Among the inflationary models based on string theory, the D3/D7 model has the advantage that the flatness of the inflaton potential can be protected even with moduli stabilization. However, the Abrikosov-Nielsen-Olesen BPS cosmic strings produced at the end of original D3/D7 inflation lead to an additional contribution to the CMB anisotropy. To make this contribution consistent with the WMAP results one needs an extremely small gauge coupling in the effective D-term inflation model. Such couplings may be difficult to justify in string theory. Here we develop a generalized version of the D3/D7 brane model, which leads to semilocal strings, instead of the topologically stable ANO cosmic strings. We show that the semilocal strings have unbroken supersymmetry when embedded into supergravity with FI terms. The energy of these strings is independent of their thickness. We confirm the existing arguments that strings of such type disappear soon after their formation and do not pose any cosmological problems, for any value of the gauge coupling. This should simplify the task of constructing fully realistic models of D3/D7 inflation.

description: The sense of touch is essential for reliable mapping between the environment and a robot which interacts physically with objects. Presumably, an artificial tactile skin would facilitate safe interaction of the robots with the environment. In this work, we present our color-coded tactile sensor, incorporating plastic optical fibers (POF), transparent silicone rubber and an off-the-shelf color camera. Processing electronics are placed away from the sensing surface to make the sensor robust to harsh environments. Contact localization is possible thanks to the lower number of light sources compared to the number of camera POFs. Classical machine learning techniques and a hierarchical classification scheme were used for contact localization. Specifically, we generated the mapping from stimulation to sensation of a robotic perception system using our sensor. We achieved a force sensing range up to 18 N with the force resolution of around 3.6~N and the spatial resolution of 8~mm. The color-coded tactile sensor is suitable for tactile exploration and might enable further innovations in robust tactile sensing.

Quality Improvement Project to Enhance Provider Awareness and Use of the Coping Strategies Questionnaire (CSQ) to Assess Patients' Level of Coping with Chronic Pain
Creators: name: Hand, Aloha D

Chronic pain is a public health problem that has an effect on 20-30% (100 million) of the population of Western countries, with costs to manage chronic pain ranging from $560 to $635 billion annually.  Many chronic body system problems, especially those involving musculoskeletal and neurological sequelae, aggravate the pain sensation over time.  Chronic pain is depicted by physical dysfunction, disability, and mood alteration; exacerbated by a lack of appropriate coping strategies. Treatment for patients with chronic pain, by providers, has been proven to be inadequate, secondary to providers’ reports of lack of time and lack of a consistent, efficient, effective protocol, and tool for assessment of patients’ chronic pain and coping. Therefore, it was necessary to investigate a method for providers to assess and intervene with patients to foster improved health outcomes and aid them in coping with chronic pain.  The Coping Strategies Questionnaire (CSQ) was developed, refined, and decreased from the original 50-item questionnaire to a more ‘user-friendly’ 14-item version. The shorter CSQ has been proven to be a valid and reliable tool in assessing coping strategies for patients with chronic pain.  Consistent results in identifying patients who have low to poor coping strategies have been produced when using the refined 14-item CSQ.   The goals and objectives of this quality improvement project were to pilot the use of the CSQ to assess patients with chronic pain within a targeted primary care practice and to offer providers a sustainable use tool that identifies patients’ positive and negative coping mechanisms. With the CSQ data in hand providers were able to intervene when patients demonstrated ineffective coping.  This paper describes the results and success of the intervention including providers’ comments and commitment to sustainable use of the CSQ.
On the Insignificance of Photochemical Hydrocarbon Aerosols in the Atmospheres of Close-in Extrasolar Giant Planets

description: The close-in extrasolar giant planets (CEGPs) reside in irradiated environments much more intense than that of the giant planets in our solar system. The high UV irradiance strongly influences their photochemistry and the general current view believed that this high UV flux will greatly enhance photochemical production of hydrocarbon aerosols. In this letter, we investigate hydrocarbon aerosol formation in the atmospheres of CEGPs. We find that the abundances of hydrocarbons in the atmospheres of CEGPs are significantly less than that of Jupiter except for models in which the CH$_4$ abundance is unreasonably high (as high as CO) for the hot (effective temperatures $\gtrsim 1000$ K) atmospheres. Moreover, the hydrocarbons will be condensed out to form aerosols only when the temperature-pressure profiles of the species intersect with the saturation profiles--a case almost certainly not realized in the hot CEGPs atmospheres. Hence our models show that photochemical hydrocarbon aerosols are insignificant in the atmospheres of CEGPs. In contrast, Jupiter and Saturn have a much higher abundance of hydrocarbon aerosols in their atmospheres which are responsible for strong absorption shortward of 600 nm. Thus the insignificance of photochemical hydrocarbon aerosols in the atmospheres of CEGPs rules out one class of models with low albedos and featureless spectra shortward of 600 nm.

description: We study the existence and charaterization of self-trapping phenomena in discrete-time quantum walks. By considering a Kerr-like nonlinearity, we associate an acquisition of the intensity-dependent phase to the walker while it propagates on the lattice. Adjusting the nonlinear parameter ($χ$) and the quantum gates ($θ$), we will show the existence of different quantum walking regimes, including those with travelling soliton-like structures or localized by self-trapping. This latter scenario is absent for quantum gates close enough to Pauli-X. It appears for intermediate configurations and becomes predominant as quantum gates get closer to Pauli-Z. By using $χ$ versus $θ$ diagrams, we will show that the threshold between quantum walks with delocalized or localized regimes exhibit an unusual aspect, in which an increment on the nonlinear strength can induce the system from localized to a delocalized regime.
