Abstract Objective:Objective: The purpose of this pilot study is to examine patients' experience and satisfaction using telemedicine for knee and hip osteoarthritis care during the COVID-19 pandemic. Methods:Methods: Adult patients seen via telemedicine for knee and/or hip osteoarthritis pain completed surveys through the REDCap online platform or pen/paper evaluating their experiences and satisfaction with telemedicine, assessed using yes/no and Likert scale questions. Demographic information was collected from the electronic medical record (EMR). Results:Results: 32 subjects (9 males, 23 females, mean age 63.2 years [SD = 12.2 years]) completed surveys. 90.6% of subjects stated that they were satisfied with the audio/video quality of their telemedicine visit. The majority of subjects responded favorably (agree or strongly agree) to survey statements about whether the doctor explained their condition/problem (93.8%), the subject understood their treatment (96.9%), the doctor answered their questions (93.8%), the doctor spent enough time during their visit (93.8%), the patient was satisfied with their telemedicine visit (90.6%), the patient was interested in future telemedicine visits (68.8%), and the patient would recommend telemedicine visits to others (78.1%). Conclusion:Conclusion: Survey respondents expressed overall satisfaction and positive experiences with seeing a physiatrist for knee or hip osteoarthritis via telemedicine. Telemedicine has been demonstrated to be a useful tool for patient visits during the COVID-19 pandemic.
Locally produced legumes and seaweed. Sustainable protein sources for a self-sufficient European animal production?

Summary The animal feeding industry is looking for new local sources of high quality protein in order to reduce import and ensure sustainable and environmental friendly animal production systems. Local legumes and seaweeds may be alternative sources of protein. We present in this paper the background for the ongoing Norwegian Research Council project Legumes and seaweeds as alternative protein sources for sheep (AltPro), which aims to investigate the suitability and potential of legumes and seaweeds as new and underutilized protein sources in sheep diets. The project addresses several critical aspects for the future development of the agriculture industry in Norway applicable to other European countries from an integrated social and natural scientific approach: 1. use of protein sources alternative to soya, 2. environmental, climatic, societal and economical sustainability, 3. animal health and welfare.

Openness and Growth: Re-Examining Foreign Direct Investment, Trade and Output Linkages in Latin America

The openness–growth connection is still an open question in the empirical literature. Although some studies have found that openness has a positive impact on economic performance, others have seriously questioned the significance of this result. The main point that we try to emphasise in this paper is that openness involves more than just trade liberalisation. The increasing importance of international capital flows and especially foreign direct investment (FDI) seems to be another relevant component of outward oriented policies. Therefore, by using quarterly data from the late seventies to 2000, we investigate the effects of liberalisation in Mexico, Brazil and Argentina by taking into account trade and FDI growth links. The results suggest that it is important to consider both exports and FDI to ascertain the benefits associated to the outward oriented strategies followed by these countries.
Effect of temperature on the expression of IFN-1 (α), STAT-1 and Mx-1 genes in Oncorhynchus mykiss (Salmoniformes: Salmonidae) exposed with the virus of the infectious pancreatic necrosis (IPNV)

El virus de la necrosis pancreatica infecciosa (IPNV) es el agente etiologico de una enfermedad aguda bien caracterizada en salmonidos alrededor del mundo. Los signos clinicos y la tasa de mortalidad dependen de varios factores tales como la dosis viral, la edad del pez y la temperatura del agua, entre otros. Un estudio experimental se llevo a cabo para medir el efecto de la temperatura sobre el perfil de expresion genica de IFN-1(α), STAT-1 y Mx-1 en alevines de trucha arcoiris expuestos con IPNV. Los alevines (n=198) fueron expuestos a 8, 12 y 16°C, y se tomaron muestras durante 21 dias para determinar el titulo viral y la expresion genica. En los primeros 11 dias el mayor titulo viral se registro a 8oC en comparacion con 12 y 16. A 8°C, existio un incremento significativo en el dia 4 del ARNm de Mx-1 (t-test, p<0.05), momento en que el titulo viral empezo a disminuir. Ademas conforme el titulo viral aumentaba, tambien STAT-1 y Mx-1 aumentaron (r=0.91) y (r=0.96) respectivamente. Los animales fueron capaces de recuperarse desde el dia 4 de algunos de los sintomas de IPN. La enfermedad clinica se desarrollo unicamente en peces expuestos a 12°C y todos murieron entre el dia 6 y 14, a pesar del incremento altamente significativo mostrado en el nivel promedio de expresion de Mx-1 a 12°C, comparados con los valores registrados a 8 y 16°C (Tukey, p<0.0001). Ademas los perfiles de expresion de IFN-1(α) y STAT-1 decrecieron el dia 7 completamente (~0.016) y (~0.020) veces, respectivamente. El nivel de expresion promedio mas alto de IFN-1(α) se registro a 16°C (Tukey, p<0.0005). Los alevines expuestos a 16°C se mostraron normales durante el experimento. IFN-1(α) posiblemente genero un efecto protector desde el dia 2 cuando mostro un aumento significativo en comparacion con los resultados a 8 y 12°C (t-student, p<0.0001); sin embargo, STAT-1 no fue afectado de manera significativa por la temperatura, aunque el mas alto valor de expresion promedio se registro a 16°C. Nuestra investigacion confirma que la expresion de genes relevantes de respuesta antiviral como IFN-1(α), STAT-1 y Mx-1 son fisiologicamente modulados por la temperatura del agua, influyendo directamente en el desarrollo de la enfermedad de IPN en trucha arcoiris.
Algebraic & Geometric Topology

We study exact Lagrangian fillings of Legendrian links of D n –type in the standard contact 3 –sphere. The main result is the existence of a Lagrangian filling, represented by a weave, such that any algebraic quiver mutation of the associated intersection quiver can be realized as a geometric weave mutation. The method of proof is via Legendrian weave calculus and a construction of appropriate 1 –cycles whose geometric intersections realize the required algebraic intersection numbers. In particular, we show that, in D –type, each cluster chart of the moduli of microlocal rank-1 sheaves is induced by at least one embedded exact Lagrangian filling. Hence, the Legendrian links of D n –type have at least as many Hamiltonian isotopy classes of Lagrangian fillings as cluster seeds in the D n –type cluster algebra, and their geometric exchange graph for Lagrangian disk surgeries contains the cluster exchange graph of D n –type.
Analysis and Mitigation of Dead Time Harmonics in the Single-Phase Full-Bridge PWM Converter with Repetitive Controllers

In order to prevent the power switching devices (e.g., the Insulated-Gate-Bipolar-Transistor, IGBT) from shootthrough in voltage source converters during a switching period, the dead time is added either in the hardware driver circuits of the IGBTs or implemented in software in Pulse-Width Modulation (PWM) schemes. Both solutions will contribute to a degradation of the injected current quality. As a consequence, the harmonics induced by the dead time (referred to as "dead time harmonics" hereafter) have to be compensated in order to achieve a satisfactory current quality as required by standards. In this paper, the emission mechanism of dead time harmonics in single-phase PWM inverters is thus presented considering the modulation schemes in details. More importantly, a repetitive controller has been adopted to eliminate the dead time effect in single-phase grid-connected PWM converters. The repetitive controller has been plugged into a proportional resonant-based fundamental current controller so as to mitigate the dead time harmonics and also maintain the control of the fundamentalfrequency grid current in terms of dynamics. Simulations and experiments are provided, which confirm that the repetitive controller can effectively compensate the dead time harmonics and other low-order distortions, and also it is a simple method without hardware modifications.
Financial and Fiscal Interaction in the Euro Area Crisis : This Time was Di erent

This paper highlights the anomalous characteristics of the Euro Area `twin crises' by contrasting the aggregate macroeconomic dynamics in the period 2009-2013 with the business cycle uctuations of the previous decades. We report three stylised facts. First, the contraction in output was marked by an anomalous downfall in investment, while consumption, savings and unemployment followed their historical relation with GDP. Second, households' and nancial corporations' debts, and house prices deviated from their pre-crisis trends. Third, the jump in the public de citGDP ratio in 2008-2009 was unprecedented and so was the scal consolidation that followed. Our analysis points to the nancial nature of the crisis as a likely explanation for these facts. Importantly, the `anomaly' in public de cit is in large part explained by extraordinary measures in support of the nancial sector, which show up in the stockow adjustments and reveal a key interaction between the scal and the nancial sectors.

Operating the Irish power system with increased levels of wind power

This paper summarises some of the main impacts of large amounts of wind power installed in the island of Ireland. Using results from various studies performed on this system, it is shown that wind power will impact on all time frames, from seconds to daily planning of the system operation. Results from studies examining operation of the system with up to approximately 40% of electricity provided by wind show that some of the most important aspects to be considered include the type of wind turbine technology, the provision of reserve to accommodate wind forecasting error and the method used to plan plant schedules.
Job Market Signaling of Relative Position , or Becker Married to

This paper considers a matching model of the labour market where workers, with private information on their quality, signal to firms that also differ in quality. Signals allow assortative matching in which the highest quality workers send the highest signals and are hired by the best firms. Matching is considered both when wages are rigid (non-transferable utility) and when they are fully flexible (utility is transferable). In both cases, equilibrium strategies and payoffs depend on the distributions of types of workers and the distribution of firms. This is in contrast with separating equilibria of the standard model which do not respond to changes in supply or demand. With sticky wages, despite incomplete information, equilibrium investment in education by low ability workers can be inefficiently low and this distortion can become worse in a more competitive environment. In contrast, with flexible wages, greater competition improves efficiency. JEL numbers: C72, C78, D82
Immigrant males’ knowledge influences baboon troop movements to reduce home range overlap and mating competition

Mechanistic models suggest that individuals’ memories could shape home range patterns and 21 dynamics, and how neighbours share space. In social species, such dynamics of home range overlap 22 may be affected by the pre-dispersal memories of immigrants. We tested this “immigrant knowledge 23 hypothesis” in a wild population of chacma baboons ( Papio ursinus ). We predicted that overlap 24 dynamics with a given neighbouring troop’s home range should reflect males’ adaptive interests in 25 overlap when the alpha male had immigrated from this neighbouring troop but less so when the 26 alpha male originated from elsewhere. We used data collected between 2005 and 2013 on two 27 neighbouring troops in Namibia, comprising GPS records of daily ranges, male natal origins, daily 28 females’ reproductive status, and a satellite index of vegetation growth. We found support for our 29 prediction in line with male reproductive strategies but not in line with foraging conditions. In 30 periods with a higher relative number of fertile females over adult males in the focal troop, male 31 baboons would benefit from reducing overlap with their neighbours to mitigate the costs of 32 between-troop mating competition. This was indeed observed but only when the alpha male of the 33 focal troop was an immigrant from that neighbouring troop, and not with alpha males of other 34 origins, presumably due to their different knowledge of the neighbouring troop. Our findings 35 highlight the role of reproductive competition in the range dynamics of social groups, and suggest 36 that spatial segregation between groups could increase through the combination of dispersal and 37 memory.
The Size Evolution of Galaxies since z~3: Combining SDSS, GEMS, and FIRES

We present the evolution of the luminosity-size and stellar mass-size relations of luminous (LV ≳ 3.4 × 1010 h L☉) and massive (M* ≳ 3 × 1010 h M☉) galaxies in the last ~11 Gyr. We use very deep near-infrared images of the Hubble Deep Field-South and the MS 1054-03 field in the Js, H, and Ks bands from FIRES to retrieve the sizes in the optical rest frame for galaxies with z > 1. We combine our results with those from GEMS at 0.2 < z < 1 and SDSS at z ~ 0.1 to achieve a comprehensive picture of the optical rest-frame size evolution from z = 0 to 3. Galaxies are differentiated according to their light concentration using the Sérsic index n. For less concentrated objects, the galaxies at a given luminosity were typically ~3 ± 0.5 (±2 σ) times smaller at z ~ 2.5 than those we see today. The stellar mass-size relation has evolved less: the mean size at a given stellar mass was ~2 ± 0.5 times smaller at z ~ 2.5, evolving proportionally to (1 + z)-0.40±0.06. Simple scaling relations between dark matter halos and baryons in a hierarchical cosmogony predict a stronger (although consistent within the error bars) than observed evolution of the stellar mass-size relation. The observed luminosity-size evolution out to z ~ 2.5 matches well recent infall model predictions for Milky Way-type objects. For low-n galaxies, the evolution of the stellar mass-size relation would follow naturally if the individual galaxies grow inside out. For highly concentrated objects, the situation is as follows: at a given luminosity, these galaxies were ~2.7 ± 1.1 times smaller at z ~ 2.5 (or, put differently, were typically ~2.2 ± 0.7 mag brighter at a given size than they are today), and at a given stellar mass the size has evolved proportionally to (1 + z)-0.45±0.10.
research The rhetoric of closed borders: Quotas, lax enforcement and illegal immigration

Governments do not always enforce their laws, even when they have the means of doing so, and lax enforcement is common in the domain of immigration policy. To explain this paradox we develop a political agency model where gains from migration are unevenly distributed, and an elected government chooses both quotas and their enforcement. We show that distributional concerns can have perverse eﬀects on migration policy since a utilitarian government may set a quota to appease the electorate, but then strategically under-invest in its enforcement. Under-investment is more likely, the larger the preference gap between median and average voter, and the higher the likelihood of a populist challenger gaining oﬃce. Our analysis also indicates that redistributive taxation reducing the share of enforcement cost borne by the median voter exacerbate the problem, whereas a compensatory tax rebate (cid:12)nanced through a tax on pro(cid:12)ts from migration alleviates the con(cid:13)ict of interest, thus reducing illegal immigration. \(.) our government turns a blind eye to the thousands of people who illegally cross our borders. These scenarios exists because corporate America has convinced our leaders that this is one of the best ways to remain competitive" Lou Dobbs 1 \When people make allegations about those here illegally the Home Oﬃce must act. Cur-rently only 6 in 100 reports of illegal immigrants result in an actual investigation and only 1.5 in 100 result in removal. ’" the Rt. Hon.

An examination of the challenges of capturing the value of adventurous off-road cycling : a perspective from South West England

Purpose-built off-road cycling infrastructure represents a relatively new form of tourism and recreation product. Over the last decade, widespread development of these facilities has taken place in the UK, primarily within forest and woodland areas. The justification for developing these sites has largely centred on their ability to generate positive economic benefits for the tourism and leisure economy. In contrast to the focus on growth and investment, relatively little attention has been paid to understanding the extent to which off-road cycling benefits the tourism and leisure economy. Furthermore, even less is known about the visitor dimension. Developing a better understanding of these interrelated aspects forms the basis of this research. This study presents a dedicated method for critically examining the nexus between off-road cycling and the tourism and leisure economy. This relationship was investigated through the lens of the 1 South West Project, which has the purpose of developing the South West into a premier off-road cycling region. The research focuses on Haldon Forest Park located on the outskirts of Exeter, in Devon. The findings from the large scale questionnaire survey (n = 486) reveal that the off-road cycling facilities are valued highly by users and are regarded as an important regional asset for tourism and recreation. Furthermore, the site was found to attract a broad range of off-road cycling visitors, and have a significant interaction with the regional economy. Interviews conducted with off-road cyclists also identified an emotional connection between off-road cycling and the forest environment. Respondents also emphasised the importance of the informal and social aspects of the activity. The approach taken by this study has enabled the intersection between visitor expenditure and consumer behaviour at purpose-built off-road cycling sites to be explored in detail. This aspect has been largely ignored within the off-road cycling literature, which has failed to look beyond basic economic transactions and acknowledge the presence of visitor sub-groups. Using Cluster Analysis to address these limitations, this study was able to identify behavioural and economic variations among visitors, and from this produce a detailed typology of users at Haldon Forest Park. This information provides important baseline data for the 1 South West Project, and has important practical implications for the future management of the off-road cycling infrastructure and onsite facilities. Furthermore, this study makes a methodological contribution to the literature through its innovative use of Cluster Analysis, as part of a dual approach to examining the economic contribution of off-road cycling.
A Project Management Approach to Using Simulation for Cost Estimation on Large , Complex Software Development Projects

It is very difficult for project managers to develop accurate cost and schedule estimates for large, complex software development projects. None of the approaches or tools available today can estimate the true cost of software with any high degree of accuracy early in a project. This paper provides an approach that utilizes a software development process simulation model that considers and conveys the level of uncertainty that exists when developing an initial estimate. A NASA project will be analyzed using simulation and data from the Software Engineering Laboratory to show the benefits of such an approach.
Hyperspectral Imagery: A New Technique for Targeting and Intelligence

Abstract : Because all materials reflect, absorb, or emit photons in ways characteristic of their molecular makeup, a high-resolution trace of the intensity of the transmitted, reflected, emitted, or luminesced radiation versus wavelength forms a graphical record unique to a given material. The laboratory use of spectral measurements to identify minerals, pigments, and organic and inorganic compounds is an established and reliable technique; and, the reasoning goes, if such could be done from air or space, it would give remote sensing a similar capability. Unfortunately, the useful absorption bands are narrow, 10 nm or less, and cannot be recorded with broad band systems such as Landsat. With the advent of the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) and similar systems, the narrow band capability entered the remote sensing domain. AVIRIS is a true spectrometer, collecting reflected solar energy (0.4-2.5 micra) in about 220 channels, or images, each in a spectral bandwidth of about 9.6 nm. This type of narrow band information is called hyperspectral. Hyperspectral Imagery, Remote Sensing, Landsat, Intelligence.
