In the absence of vaccines that provide complete protection against these viruses, viral surveillance can identify disease burden and target virus-specific preventative measures. Influenza infection, in particular, has significant adverse effects on force readiness. Methods We tracked the frequency of 16 respiratory viruses at Walter Reed National Military Medical Center tested for during routine patient care using multiplex polymerase chain reaction and rapid antigen testing. We collected data on the date and location of the testing, as well as the age of the individual tested from two consecutive respiratory viral seasons. Results During the first year of data compilation (2017-2018), 2556 tests were performed; 342 (13.4%) were positive for influenza A and 119 (4.7%) were positive for influenza B. After influenza, the most common familie...

Our project delivers an innovative approach to relaying vehicle information to the driver via a dual mode instrument cluster/HUD. We implemented our design in a manner that compliments the user’s driving ability and not hamper it by being a distraction. The addition of a touch screen display in the vehicle’s center console adds another layer to the vehicle—driver dynamic. Careful consideration has been placed upon safety of use, cost effectiveness and real

These fungi gather and exchange mineral nutrients with plants for photosynthetically derived carbohydrates. Mycorrhizal fungi can also confer other benefits onto plants, e.g. defense against pathogens, improved water relations, tolerance to heavy metal toxicity and herbivory. The influence of mycorrhizal fungi on plant mineral nutrition and response to stress suggests that these organisms may have a role to play sustainable agriculture as well as in bioremediation and ecosystem restoration. In contributing to this important research, I investigated host-specific interactions between mycorrhizal fungi and the sex morphs of the gynodioecious perennial herb Polemonium foliosissimum (Polemoniaceae) and their mycorrhizal associates in the field. I hypothesized that the genders of this species differed in their associations with mycorrhizal fungi in benefits received. I performed ...

This article argues that, rather than being offhand allusions, those references lie at the core of a deeper political, religious, and literary interest in the figure and writings of the sixteenth-century Spanish writer. Southey’s contribution to the criticism of the so-called “Phoenix of Wits” might be difficult to assess, not least because in a period of over twenty years he went from asserting that “Lope de Vega is never sublime, seldom pathetic, and seldom natural” (CLRS 188) in a series of public letters he contributed to the Monthly Magazine in 1796, to becoming a true aficionado of this “prodigy of nature,” in 1818 celebr...

In order to satisfy the requirements of 6G applications, we investigate a non-uniform rectangular array (NURA) structure with FD-MIMO antenna systems for the multiuser mmWave communications. For the dense scenarios where the number of users to be served is high, we propose user selection algorithms for both digital and hybrid transceiver designs in FD-MIMO with NURA for the multiuser mmWave communications. For the digital transceivers, the users are selected based on their channel correlation considering FD-MIMO with NURA structures. For the hybrid transceivers, sequential user and beam selection is performed using the correlation between the beamspace channels in FD-MIMO with NURA case. The superiority of the NURA compared to uniform antenna structure is shown through the performance evaluations in the multiuser mmWave communications. Besides, the sum data rate results and complexity analysis denote the feasibility of the proposed algorithms compared to the joint user and beam selection schemes. INDEX TERMS Full dimensional MIMO, millimeter wave, non-uniform rectangular array, user selection.

The Teleneurology Program at the Hospital Las Higueras de Talcahuano (HHT) was implemented in 2015 to help reduce both the number of patients waiting for a first consultation and their waiting times. Methods This retrospective study analyzed a cohort of 8269 patients referred to the HHT Neurology clinic between 2013 and 2018, from primary, secondary, and tertiary health centers. Cox regression analyses were performed to determine the factors influencing each outcome (number of patients waiting for a consultation and waiting time), such as age, gender, referral health establishment and the type of consultation (whether in situ at the HHT or by synchronic telepresence through the Teleneurology Program). Results Out of the 8269 patients included in the study, 1743 consulted the neurologist through the...

The following interview took place there on May 26, 2017 and was later expanded through e-mail. Posing a number of questions with a series of illuminating and often provocative responses, it seeks to delve into Doyle's own ideas on Ireland and Irish literature, together with his attitude about life and creative writing, in order to shed some light on what this author looks for and what he wants to prove with his works, an important new voice in Irish writing that is determined to take the tradition in new and significant directions.

Delineation of molecular profiles in ACC has led to an increased number of biomarker-stratified clinical trials; however, the clinical utility and U.S.-centric financial sustainability of integrated next-generation sequencing (NGS) in routine practice has, to our knowledge, not been assessed. Materials and Methods In our practice, NGS genotyping was implemented at the discretion of the primary clinician. We combined NGS-based mutation and fusion detection, with MYB break-apart fluorescent in situ hybridization (FISH) and MYB immunohistochemistry. Utility was defined as the fraction of patients with tumors harboring alterations that are potentially amenable to targeted therapies. Financial sustainability was assessed using the fraction of global reimbursement. Results Among 181 consecutive ACC cases (2011–2018), prospective genotyping was performed in 11% (n = 20...

The epidemic was driven by race T, a previously unseen race of Cochliobolus heterostrophus. A second fungus, Phyllosticta zeae-maydis, with the same biological specificity, appeared coincidentally. Race T produces T-toxin, while P. zeae-maydis produces PM-toxin, both host selective polyketide toxins necessary for supervirulence. Present abundance of genome sequences offers an opportunity to tackle the evolutionary origins of T- and PM- toxin biosynthetic genes, previously thought unique to these species. Using the C. heterostrophus genes as probes, we identified orthologs in six additional Dothideomycete and three Eurotiomycete species. In stark contrast to the genetically fragmented race T Tox1 locus which encodes these genes, all newly found Tox1-like genes in other species reside at a single collinear locus. This compact arrangement, phylogenetic ...

They commonly harbour endobacteria of a largely unknown biology, referred to as MRE (Mollicutes/mycoplasma-related endobacteria). Here, we propose to accommodate MRE in the novel genus 'Candidatus Moeniiplasma.' Phylogeny reconstructions based on the 16S rRNA gene sequences cluster 'Ca. Moeniiplasma' with representatives of the class Mollicutes, whereas phylogenies derived from amino acid sequences of 19 genes indicate that it is a discrete lineage sharing ancestry with the members of the family Mycoplasmataceae. Cells of 'Ca. Moeniiplasma' reside directly in the host cytoplasm and have not yet been cultivated. They are coccoid, ~500 nm in diameter, with an electron-dense layer outside the plasma membrane. However, the draft genomes of 'Ca. Moeniiplasma' suggest that this structure is not a Gram-positive cell wall. The evolution of 'Ca. Moeniiplasma&...

The Review of English Studies, 2016

For her first chapter, Valladares borrows her title, 'Pizarro, "Political Proteus"', from William Cobbett's critique (1804) addressing the reinterpretations of Sheridan's play season after season as similar to the shifting alliances of Sheridan's politics. What for Cobbett was protean instability becomes for Valladares protean adaptability. In her introduction she announces her critical emphasis on the plurality of a play's meaning from one performance to the next, 'enabling possibilities of playing across seemingly demarcated lines' (3). Even at the time of its opening (Drury Lane, 24 May 1799), Pizarro was perceived to implicate a doubleness. Sheridan's Conquistadores may bear a Spanish standard but they could represent as well soldiers in Napoleon's army, while the Peruvian natives could be as English as the actors playing them. The audience would certainly share in the prevailing alarm that Napoleon was planning a full-scale invasion of England. Eight years later another protean change took place in the performance. Pizarro was still the ruthless conqueror, but it was now Spain that his armies had invaded. Portugal was a long-time ally, and its port in Lisbon was crucial to Britain's international trade. Spain was no such ally, and recollections of the Spanish Armada of 1588 continued to nurture suspicions of lurking hostility. But in May 1808 widespread resistance against French occupation rose up in opposition to Napoleon's attempt to place his brother, Joseph Bonaparte, on the Spanish throne. Allegiances shifted. Sheridan's play took on new political relevance. In her second chapter, 'Performing Shakespeare', Valladares further develops her argument on the plurality of interpretations. She cites from Biographia Literaria (1817) Coleridge's argument that the war in Spain and Portugal 'made us all once more Englishmen'. She observes, too, a congruency between prevailing political sentiment and Coleridge's representation of the Spaniards in his Remorse (Drury Lane, 23 January 1813). Identifying Shakespeare as the national bard, Coleridge traces in his lectures an abiding ideological relevance of the plays. Contending that Shakespeare's plays were used to bolster nationalism and 'to (re)figure concerns about the British military action in the Iberian Peninsula' (59), Valladares examines Henry V and Henry VIII among her examples of plays of nationalism. The former achieved its success by ennobling the English and exposing the debased morality of the French; the latter suggested the wrongs to the Spanish people were represented in the role of Katherine of Spain. From the Roman plays she selects Julius Caesar and Coriolanus, emphasizing in each the divisive factions of authority and the exploitation of public feelings. In Chapter 3 Valladares turns her attention to the 'Spectacular Stages', the unlicensed theatres of London. The Licensing Act (1737) required the Lord Chamberlain's approval of all plays. Traditional spoken drama was restricted to the three licensed theatres, Covent Garden, Drury Lane, and during the summer season the Haymarket. The unlicensed theatres were originally limited to song and pantomime. The very strictures of the Licensing Act prompted considerable innovation, so that older forms of dramatic performance (harlequinades, masques) were revised, new forms (burlesque, burletta, melodrama) gained

In the United States, body dissatisfaction tends to be associated with depression, disordered eating, and incongruent weight evaluations, particularly among white women and women of higher socioeconomic status. However, it remains unclear how being overweight and obesity are interpreted by Mexican women. Using comparable data of women aged 20–64 from both Mexico (the 2006 Encuesta Nacional de Salud y Nutricion; N = 17,012) and the United States (the 1999–2009 National Health and Nutrition Examination Surveys; N = 8,487), we compare weight status evaluations among Mexican nationals, Mexican immigrants, US-born Mexicans, US-born non-Hispanic whites, and US-born non-Hispanic blacks. Logistic regression analyses, which control for demographic and socioeconomic variables and measured body mass index and adjust for the likelihood of migration for Mexican nationals, indicate that the tendency to self-evaluate as overw...

These systems provide lot of usability to their environments because they improve the way that the workers utilize vehicles in fleets. They have helped the enterprises to detect delayed deliveries, routes detours, urgent maintenance reports and oil saving. In Cuba the system used by majority of enterprises was one that does not make route monitoring during vehicles trip making almost impossible to control if there was any inconvenience during the trajectory of the vehicle, causing the loss of several minutes and even hours to help the broken vehicle to get back in service again. In this paper a proposal to fix this is made by using coordinates taken from a GPS device and stored in KML or GPRMC format files. The system besides will allow supervisors the creation of routes and areas assigned to vehicles in fleets, in which the behavior of the vehicle will be reflected lunching alarms when the vehicle incurs in detouring problem and even in an over-speed problem. Also all the irregularities detected during a movement of vehicle will be registered in a database for supervisor revising purpouses.

Given this broader context, in this article we examine ways that we might join implementation of dual language programs, Common Core State Standards, and critical pedagogy at the school and classroom levels via a teacher, school administrator, and teacher professional development program. We focus on a concrete example of a partnership between a progressive dual language school along the U.S.-Mexico border, known as Chula Vista Learning Community Charter School, and a bilingual teacher education program in the College of Education at San Diego State University, which prepares teachers and administrators to implement and develop dual language instruction aligned (but not beholden) to Common Core State Standards. We include discussion of a Freirian-based instructional program that helps unite the opportunities presented by dual language programs and standardsbased reform initiatives in a deeper equity and social justice framework for educating students. We discuss opportunities (oportunidades), strategies (estrategias), and challenges (retos) encountered during this collaborative work between the bilingual teacher preparation program, a Dual Language school, and one exemplary fourth grade teacher team and their enactment of a critical pedagogy-based curriculum. We conclude with a discussion of implications of our work for education of multilingual learners and the educators that work with them.

Bilingual teachers need to develop knowledge and skills to succeed in teaching diverse students. Demographic shifts are bringing increasing numbers of international students from diverse racial, ethnic, religious, class, and linguistic backgrounds into the United States public schools. The goal of this article is not to debate whether it is important to address diversity in the public schools. Instead, the goal is to help teacher educators think about diversity in a global and integrative manner by providing important and valuable perspectives about the internationalization of teacher education. Las migraciones demográficas están trayendo cantidades de estudiantes internacionales de diversos trasfondos raciales, étnicos, religiosos, lingüísticos y de diferentes clases sociales a las escuelas públicas de Estados Unidos. La meta de este artículo no es discutir si es importante señalar la diversidad en las escuelas públicas. En cambio, la meta es ayudar a los que son educadores de profesores a reflexionar acerca de la diversidad de una manera global e integrada, proveyendo perspectivas importantes y valiosas en cuanto a la internacionalización de la educación pedagógica.

However, the relationship between soil nutrient availability and litterfall is poorly defined along natural soil fertility gradients, especially in tropical montane forests. Here, we measured litterfall for two years in five lower montane 1‐ha plots spanning a soil fertility and precipitation gradient in lower montane forest at Fortuna, Panama. Litterfall was also measured in a concurrent nitrogen fertilization experiment at one site. Repeated‐measures ANOVA was used to test for site (or treatment), year, and season effects on vegetative, reproductive and total litterfall. We predicted that total litterfall, and the ratio of reproductive to leaf litterfall, would increase with nutrient availability along the fertility gradient, and in response to nitrogen addition. We found that total annual litterfall varied substantially among 1‐ha plots (4....

This fact has led to the introduction of new integrated control methods in citrus orchards, including the implementation of techniques based on pheromones. Previous works described efficient mating disruption pheromone dispensers to control A. aurantii in the Mediterranean region. The main aims of the present study were to adjust the timing of dispenser applications and study the importance of controlling the early first generation of A. aurantii by testing two different application dates: before and after the first CRS male flight. The efficacy of the different mating disruption strategies was tested during 2010 in an experimental orchard and these results were confirmed during 2011 in a commercial citrus farm. Results showed that every mating disruption strategy achieved significantly lower male captures in monitoring pheromone traps compared with untreated plots, as well as mean fruit infestation reductions of about 80%. The control of the first CRS generation is not essential for achieving a good efficacy as demonstrated in two locations with different pest pressure. The late application of MD dispensers before the second CRS male flight has proven to be effective, suggesting a new advantageous way to apply mating disruption.

New control methods compatible with biological control are required, and mating disruption appears to be a perfect method in current agriculture, as it is an environmentally friendly and residue‐free technique. IPM packages tested have included the use of pheromones to detect populations, but there has not been much previous research on mating disruption of T. absoluta. In this work, pheromone doses varying from 10 to 40 g ha−1, emitted at a constant rate over 4 months, were tested in greenhouses with different levels of containment in order to evaluate the efficacy of mating disruption on T. absoluta.RESULTS: Trials on containment level revealed that the flight of T. absoluta was satisfactorily disrupted with an initial pheromone dose of 30 g ha−1, and levels of damage did not...
