Solutions of quasianalytic equations

The article develops techniques for solving equations G(x,y)=0, where G(x,y)=G(x_1,...,x_n,y) is a function in a given quasianalytic class (for example, a quasianalytic Denjoy-Carleman class, or the class of infinitely differentiable functions definable in a polynomially-bounded o-minimal structure). We show that, if G(x,y)=0 has a formal power series solution y=H(x) at some point a, then H is the Taylor expansion at a of a quasianalytic solution y=h(x), where h(x) is allowed to have a certain controlled loss of regularity, depending on G. Several important questions on quasianalytic functions, concerning division, factorization, Weierstrass preparation, etc., fall into the framework of this problem (or are closely related), and are also discussed.Comment: revised version, 25 pages, to appear in Selecta Mat

What do commencing undergraduate students expect from first year university?

The expectations of students entering their first year of undergraduate study in South Australia were investigated. Responses from 3,091 students allowed a comprehensive understanding of students’ expectations. Most respondents (70%) were entering university directly from secondary school and most (78%) were studying in their program of first choice. The major factor in program choice was interest in the topic, followed by career prospects. The need to understand the expectations of students commencing university is becoming even more important with many universities aiming to increase participation from previously under-represented groups. Only 30% of students had realistic expectations about the amount of study required to succeed at university. Most students felt that feedback on submitted work, and on drafts of work, would be important for their learning. Having easy and convenient access to teaching staff outside of face-to-face teaching was seen as an important factor in success. Ninety-one percent of students felt that having friends studying at the same university would provide support, but 25% did not know anyone studying at the same university

Sonocubic fine: novo software de ultrassonografia tridimensional para o rastreamento das doenças cardíacas congênitas

Congenital heart disease is the most common fetal congenital malformations; however, the prenatal rate detection still is low. The two-dimensional echocardiography is the gold standard exam to screening and diagnosis of congenital heart disease during the prenatal; however, this exam is operator-depending and it is realized only in high risk pregnancies. Spatio-temporal image correlation is a three-dimensional ultrasound software that analyses the fetal heart and your connections in the multiplanar and rendering modes; however, spatio-temporal image correlation too is operator-depending and time-consuming. We presenting a new three-dimensional software named Sonocubic fine to the screening of congenital heart disease. This software applies intelligent navigation technology to spatio-temporal image correlation volume datasets to automatically generate nine fetal echocardiography standard views. Thus, this new software tends to be less operator-depending and time-consuming.Doenças cardíacas congênitas são as malformações congênitas mais frequentes, entretanto, a detecção pré-natal ainda permanece baixa. A ecocardiografia bidimensional é o padrão-ouro para o rastreamento e diagnóstico das doenças cardíacas congênitas durante o pré-natal, entretanto, é operador dependente e realizada somente em gestantes de alto risco. Spatio-temporal image correlation é um software de ultrassonografia tridimensional que analisa o coração fetal e suas conexões vasculares nos modos multiplanar e superfície, contudo, também é operador dependente e consome muito tempo. Apresentamos um novo software: Sonocubic fine para o rastreamento das doenças cardíacas congênitas. Este software aplica a inteligência da tecnologia de navegação em volumes de spatio-temporal image correlation para automaticamente gerar nove planos ecocardiográficos padrões. Além disso, esta técnica tende a ser menos operador dependente e consumir menor tempo.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

UNESP DE PORTAS ABERTAS: ESTREITANDO OS LAÇOS ENTRE UNIVERSIDADE, SERVIDORES E SEUS FAMILIARES.

O artigo trata da influência do contexto familiar na vida profissional do trabalhador, assim como da importância da identificação do servidor com a organização a qual pertence, no caso a Universidade. Nessa temática, objetiva apresentar o programa de visitas dirigidas intitulado “UNESP de Portas Abertas” desenvolvido na UNESP-Bauru, destinado aos servidores técnicos, administrativos, docentes e seus familiares, com o intuito de suprir demandas observadas em estudos de clima organizacional de anos anteriores, visando oportunizar aos servidores e seus familiares, um momento para se efetivar e ampliar informações sobre a Universidade, disponibilizando parte de sua estrutura física e intelectual a serviço dessa população. Com isso, busca-se ampliar a integração entre os servidores e respectivos familiares, fortalecer vínculos pessoais com a organização e favorecer o desenvolvimento e o resgate da auto-estima do servidor. Este artigo busca ainda apresentar os resultados da primeira experiência do projeto no ano de 2009, discutindo as possíveis melhorias na estrutura do programa como um todo

The Nature of the Density Clump in the Fornax Dwarf Spheroidal Galaxy

We have imaged the recently discovered stellar overdensity located approximately one core radius from the center of the Fornax dwarf spheroidal galaxy using the Magellan Clay 6.5m telescope with the Magellan Instant Camera (MagIC). Superb seeing conditions allowed us to probe the stellar populations of this overdensity and of a control field within Fornax to a limiting magnitude of R=26. The color-magnitude diagram of the overdensity field is virtually identical to that of the control field with the exception of the presence of a population arising from a very short (less than 300 Myr in duration) burst of star formation 1.4 Gyr ago. Coleman et al. have argued that this overdensity might be related to a shell structure in Fornax that was created when Fornax captured a smaller galaxy. Our results are consistent with this model, but we argue that the metallicity of this young component favors a scenario in which the gas was part of Fornax itself.Comment: 24 pages including 8 figures and 3 tables.

Malpais spring virus is a new species in the genus vesiculovirus

BACKGROUND: Malpais Spring virus (MSPV) is a mosquito-borne rhabdovirus that infects a variety of wild and feral ungulates in New Mexico, including horses and deer. Although, initial serologic tests and electron microscopy at the time of isolation nearly 25 years ago provided evidence that MSPV is a novel virus, possibly related to vesiculoviruses, the virus still has not been approved as a new species. FINDINGS: Use of the illumina platform allowed us to obtain the complete genome of MSPV. Analysis of the complete 11019 nt genome sequence of the prototype 85-488NM strain of MSPV indicates that it encodes the five common rhabdovirus structural proteins (N, P, M, G and L) with alternative ORFs (> 180 nt) in the N, M and G genes, including a 249 nt ORF in the G gene predicted to encode a 9.26 kDa highly basic transmembrane protein. Although antigenically very distant, phylogenetic analysis of the L gene indicates that MSPV is most closely related to Jurona virus, also isolated from mosquitoes in Brazil, as well as a number of other vesiculoviruses. CONCLUSIONS: In sum, our analysis indicates MSPV should be classified as a member of the genus Vesiculovirus, family Rhabdoviridae. The complete genome sequence of MSPV will be helpful in the development of a reverse genetics system to study the unique aspects of this vesiculovirus in vivo and in vitro, and will assist development of specific diagnostic tests to study the epidemiology of MSPV infection

Comparação entre os modos multiplanar e renderizado na avaliação da área das valvas atrioventriculares fetais por meio da ultrassonografia 3D/4D

OBJECTIVE: To compare the agreement of multiplanar and rendering modes in the assessment fetal atrioventricular valves (mitral and tricuspid) areas by three-dimensional (3D) ultrasonography using the software spatio-temporal image correlation (STIC). METHODS: We conducted a prospective cross-sectional study with normal pregnant women, with single fetuses, between 18-33 weeks. To measure the areas, we used the plan of four-chamber view. In the case of multiplanar, the plane was rotated on the axis Z form the heart to position at 9h. For rendering, the green line (region of interest - ROI) was placed from the atria of the heart perpendicular to the crux. The agreement was assessed by a Bland-Altman (limits of agreement) using the relative difference between the measures: ((rendering mode) - (multiplanar mode)) / (average). RESULTS: 328 fetuses were evaluated. We have not identified the occurrence of systematic error between methods: the average relative difference was 1.62% (-2.07% to 5.32%, confidence interval 95%) in the mitral and 1.77% (- 1.08% to 4.62%) in the tricuspid valve. The limits of agreement between methods were -65.26% to 68.51% for the mitral and -49.91% to 53.45% for the tricuspid. CONCLUSIONS: There was no systematic error between modes and thus the observed values for the area of fetal atrioventricular valves can be used for comparisons needs to be corrected. However, relatively large variations may be observed when repeating the measurement area by different modes.OBJETIVO: Avaliar a concordância entre as medidas das áreas das valvas atrioventriculares (mitral e tricúspide) fetais realizadas por ultrassonografia tridimensional (3D) pelo software spatio-temporal image correlation (STIC) usando os modos multiplanar e renderizado. MÉTODOS: Estudo prospectivo de corte transversal avaliando fetos de gestações únicas, consideradas saudáveis, entre 18 a 33 semanas de idade gestacional. Para a medida das áreas, utilizou-se o plano de quatro câmaras cardíacas. No caso do multiplanar, o plano foi rodado no eixo z de forma o coração se dispuser em 9h. Para o renderizado, a linha verde (região de interesse - ROI) foi posicionada a partir dos átrios, perpendicular à cruz do coração. A concordância foi avaliada pelo método de Bland-Altman (limites de concordância) utilizando a diferença relativa entre as medidas: ((modo renderizado) - (modo multiplanar)) / (média).< RESULTADOS: 328 fetos foram avaliados. Não identificamos a ocorrência de erro sistematizado entre os métodos: a diferença relativa média foi de 1,62% (-2,07% a 5,32%, intervalo de confiança de 95%) na mitral e de 1,77% (-1,08% a 4,62%) na tricúspide. Os limites de concordância entre os métodos foram de -65,26% a 68,51% para a mitral e de -49,91% a 53,45% para a tricúspide. CONCLUSÕES: Não foi observado erro sistematizado entre os modos e desta forma os valores observados para a área das valvas atrioventriculares fetais podem ser utilizados para comparações sem necessidades de correções. Entretanto, variações relativamente grandes podem ser observadas ao se repetir a medida da área pelos diferentes modos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Federal University of São Paulo Department of Obstetrics Division of Fetal CardiologyUniversity of São Paulo Faculty of Medicine of Ribeirão Preto Department of Obstetrics and GynecologySchool of Ultrasound and Medicine of Ribeirão Preto RecyclingNational Institute of Science and Technology (INCT) of Hormones and Women's HealthUNIFESP, Department of Obstetrics Division of Fetal CardiologySciEL
