description: Between the 16th and the 18th century, as the study of drawing emerged as a scientific procedure to write the history of European art, material cuts have transformed the way in which drawings were collected and studied. This essay examines various types of cuts, such as those operated on the drawings in the collections of Giorgio Vasari (1511-1574) and Pierre-Jean Mariette (1694-1774), and offers an explanation on how such treatment shaped the interpretation of scholars and connoisseurs through time. The case of the loose sheets by Jean-Antoine Watteau (1684-1721) shows the impact of the cuts made since the 18th century on the study of an artist’s drawn oeuvre, and particularly on the ranking of pictorial genres. Landscape drawings are cut to favour figure studies on the opposite face of the sheet. Starting in the 19th century, the systematic introduction of the labels ‘recto’ and ‘verso’ in art historical literature and museum practices has resulted in the hierarchical arrangement of the two faces, according to the evolution of taste. The philological study of the loss caused by the cut, it is argued, may promote fruitful intersections between the history of drawings’ connoisseurship, collecting and restoration.

description: Context: Late on 2013 August 19, STEREO-A, STEREO-B, MESSENGER, Mars Odyssey, and the L1 spacecraft, spanning a longitudinal range of 222° in the ecliptic plane, observed an energetic particle flux increase. The widespread solar energetic particle (SEP) event was associated with a coronal mass ejection (CME) that came from a region located near the far-side central meridian from Earth's perspective. The CME erupted in two stages, and was accompanied by a late M-class flare observed as a post-eruptive arcade, persisting low-frequency (interplanetary) type II and groups of shock-accelerated type III radio bursts, all of them making this SEP event unusual. Aims: There are two main objectives of this study, disentangling the reasons for the different intensity-time profiles observed by the spacecraft, especially at MESSENGER and STEREO-A locations, longitudinally separated by only 15°, and unravelling the single solar source related with the widespread SEP event. Results: The solar source associated with the widespread SEP event is the shock driven by the CME, as the flare observed as a post-eruptive arcade is too late to explain the estimated particle onset. The different intensity-time profiles observed by STEREO-A, located at 0.97 au, and MESSENGER, at 0.33 au, can be interpreted as enhanced particle scattering beyond Mercury's orbit. The longitudinal extent of the shock does not explain by itself the wide spread of particles in the heliosphere. The particle increase observed at L1 may be attributed to cross-field diffusion transport, and this is also the case for STEREO-B, at least until the spacecraft is eventually magnetically connected to the shock when it reaches ~0.6 au.

description: We present the results of a spectroscopic monitoring program of the Pleiades region aimed at completing the census of spectroscopic binaries in the cluster, extending it to longer periods than previously reachable. We gathered 6104 spectra of 377 stars between 1981 and 2021, and merged our radial velocities with 1151 measurements from an independent survey by others started three years earlier. With the combined data spanning more than 43 yr we have determined orbits for some 30 new binary and multiple systems, more than doubling the number previously known in the Pleiades. The longest period is 36.5 yr. A dozen additional objects display long-term trends in their velocities, implying even longer periods. We examine the collection of orbital elements for cluster members, and find that the shape of the incompleteness-corrected distribution of periods (up to $10^4$ days) is similar to that of solar-type binaries in the field, while that of the eccentricities is different. The mass-ratio distribution is consistent with being flat. The binary frequency in the Pleiades for periods up to $10^4$ days is $25 \pm 3$%, after corrections for undetected binaries, which is nearly double that of the field up to the same period. The total binary frequency including known astrometric binaries is at least 57%. We estimate the internal radial velocity dispersion in the cluster to be $0.48 \pm 0.04$ km s$^{-1}$. We revisit the determination of the tidal circularization period, and confirm its value to be $7.2 \pm 1.0$ days, with an improved precision compared to an earlier estimate.

description: Ultralight axion-like particles are well-motivated dark matter candidates that are the target of numerous direct detection efforts. In the vicinity of the Solar System, such particles can be treated as oscillating scalar fields. The velocity dispersion of the Milky Way determines a coherence time of about 10^6 oscillations, beyond which the amplitude of the axion field fluctuates stochastically. Any analysis of data from an axion direct detection experiment must carefully account for this stochastic behavior to properly interpret the results. This is especially true for experiments sensitive to the gradient of the axion field that are unable to collect data for many coherence times. Indeed, the direction, in addition to the amplitude, of the axion field gradient fluctuates stochastically. We present the first complete stochastic treatment for the gradient of the axion field, including multiple computationally efficient methods for performing likelihood-based data analysis, which can be applied to any axion signal, regardless of coherence time. Additionally, we demonstrate that ignoring the stochastic behavior of the gradient of the axion field can potentially result in failure to discover a true axion signal.

description: De entre as técnicas não invasivas de determinação do limiar anaeróbio, o método da determinação da velocidade crítica tem merecido grande atenção, nomeadamente no âmbito da avaliação e controlo do treino em natação. Neste sentido, o objetivo do presente artigo foi efetuar uma revisão da literatura do tipo qualitativa acerca do significado do parâmetro velocidade crítica e sua aplicação à natação. Foram abordadas questões relativas à origem e definição do conceito de velocidade crítica, às metodologias de determinação mais comuns, bem como uma breve referência ao conceito de velocidade crítica anaeróbia. A velocidade crítica é sugerida como um parâmetro não invasivo de avaliação do desempenho aeróbio e de predição do limiar anaeróbio de nadadores, independentemente do nível desportivo. As principais vantagens deste indicador resultam da facilidade de aplicação e análise num elevado número de nadadores, sem a necessidade da utilização de equipamentos dispendiosos ou de recolha de sangue. Aponta-se como uma ferramenta útil no mecanismo de prescrição e controlo de cargas de treino por meio de resultados em condições experimentais ou recorrendo a tempos obtidos durante as competições. A descriminação dos valores de velocidade crítica entre nadadores com diferentes perfis metabólicos (velocistas versus fundistas) e ainda a sua aplicabilidade em regime anaeróbio são aspetos que ainda carecem de um maior entendimento.

description: O objetivo desse estudo foi analisar a produção de artigos sobre comportamentos sedentários em idosos. Trata-se de uma revisão sistemática a partir da base de dados Pubmed. Os descritores utilizados foram “sedentary behavior” e “sitting time” combinados com elderly, older e aging. Foram incluídos artigos originais completos disponíveis até dezembro de 2013, que apresentassem medida do comportamento sedentário. Considerou-se o tipo de inquérito e delineamento, local da coleta dos dados, instrumentos, definição operacional e ponto de corte para comportamento sedentário. Foram encontrados 559 artigos, e desses 130 foram excluídos por duplicação, resultando em 429, desses 39 atenderam os critérios de inclusão estabelecidos. Os artigos foram publicados entre 2003 a 2013. Acelerômetro e questionário foram os instrumentos mais pronunciados para medida do comportamento sedentário nos artigos analisados. Foram identificadas lacunas na produção científica em relação aos pontos de corte para definir a quantidade de tempo sentado que representa risco à saúde das pessoas idosas, definição operacional universal, bem como falta de padronização dos instrumentos. Sugerem-se mais estudos relacionados com essa temática a fim de reduzir as lacunas existentes.

description: A atividade física proporciona benefícios para a saúde e qualidade de vida de mulheres idosas. Ainda são escassos os estudos longitudinais em mulheres idosas com duração superior a um ano de prática de exercício físico. Assim o objetivo do estudo foi analisar os efeitos de três anos de treino multicomponente na capacidade funcional de mulheres idosas. Métodos: 51 mulheres (66.7±5.30 anos e 159±0.11cm) participaram ao longo de três anos num programa constituído por períodos de nove meses de treino multicomponente seguidos de três meses de destreino. As avaliações decorreram no início/fim de cada período de treino e destreino. Resultados: No 1º, 2º e 3º ano verificaram-se aumentos estatisticamente significativos em todos os parâmetros da capacidade funcional (p<0.05). No entanto, o 2º ano revelou ser o período de treino onde observamos os maiores aumentos nos testes T6M (7.43%), SA (383.33%), AC (40.33%), FA (13.05%) e LS (12.5%) (p<0.05). Os testes T6M, LS, FA, AC, SA melhoraram entre 4.17% a 576.60% em todos os períodos de treino e diminuíram entre 3.21% a 85.31% em todos os períodos de destreino. Conclusões: Três anos de treino multicomponente contribuíram para a melhoria da capacidade funcional em mulheres idosas, principalmente no 2º ano de intervenção.

description: We study the potential of GLAST to unveil particle dark matter properties with gamma-ray observations of the Galactic center region. We present full GLAST simulations including all gamma-ray sources known to date in a region of 4 degrees around the Galactic center, in addition to the diffuse gamma-ray background and to the dark matter signal. We introduce DMFIT, a tool that allows one to fit gamma-ray emission from pair-annihilation of generic particle dark matter models and to extract information on the mass, normalization and annihilation branching ratios into Standard Model final states. We assess the impact and systematic effects of background modeling and theoretical priors on the reconstruction of dark matter particle properties. Our detailed simulations demonstrate that for some well motivated supersymmetric dark matter setups with one year of GLAST data it will be possible not only to significantly detect a dark matter signal over background, but also to estimate the dark matter mass and its dominant pair-annihilation mode.

description: The Glashow-Weinberg-Salam gauge field Lagrangian for electroweak theory and the Townsend-Zardecki action for gravitation are obtained from the same type of Yang-Mills Weil form on a principal fiber bundle over space-time, with symmetry group U(2) and SO(2,3), respectively. The unified geometrical approach given here shows that fiber bundle reduction and symmetry breaking are essential not only in electroweak theory but also in the SO(2,3) gauge theory for gravitation. In fact, the process of symmetry breaking in electroweak theory and the soldering of the anti-de Sitter bundle, essential in the interpretation of SO(2,3) gauge theory as a theory for gravitation, are corresponding geometrical concepts.

description: Context. X-ray flares are common phenomena in pre-main sequence stars. Their analysis gives insights into the physics at work in young stellar coronae. The Orion Nebula Cluster offers a unique opportunity to study large samples of young low mass stars. This work is part of the Chandra Orion Ultradeep project (COUP), an ~10 day long X-ray observation of the Orion Nebula Cluster (ONC). Aims. Our main goal is to statistically characterize the flare-like variability of 165 low mass (0.1-0.3 M_sun) ONC members in order to test and constrain the physical scenario in which flares explain all the observed emission. Methods. We adopt a maximum likelihood piece-wise representation of the observed X-ray light curves and detect flares by taking into account both the amplitude and time derivative of the count-rate. We then derive the frequency and energy distribution of the flares. Results. The high energy tail of the energy distribution of flares is well described by a power-law with index 2.2. We test the hypothesis that light curves are built entirely by overlapping flares with a single power law energy distribution. We constrain the parameters of this simple model for every single light curve. The analysis of synthetic light curves obtained from the model indicates a good agreement with the observed data. Comparing low mass stars with stars in the mass interval (0.9-1.2M_sun), we establish that, at ~1 Myr, low mass and solar mass stars of similar X-ray luminosity have very similar flare frequencies. Conclusions. Our observational results are consistent with the following model/scenario: the light curves are entirely built by over- lapping flares with a power-law intensity distribution; the intense flares are individually detected, while the weak ones merge and form a pseudo-quiescent level, which we indicate as the characteristic level.
Adolescents’ perceptions of food and food behaviors : an interpretive study
Creators: name: Lynam, Mary Judith
Publisher: name: University of British Columbia
Year: 2010

description: This study reports an investigation of teenagers' perceptions of food and their food behaviors. The study was qualitative in design. Data were collected on eleven teenagers in their homes through interviews and observations. Data were analysed using the method of constant comparative analysis. The adolescents' rationales for their food behaviors reflected both their perceptions of what was important regarding foods and food behaviors and how these perceptions or actual behaviors might change over time or as situations changed. The data were interpreted to show that teenagers have frameworks which guide their decision making about food. Processes which contributed to the development of the adolescents' frameworks were their interpretation of cues and knowledge, the comparison of themselves with others and the desire to resolve issues of personal concern. The adolescents were also described as having food behaviors directed by issues related to either "convictions" or "convenience." The knowledge guiding the teenagers' decision making was based on their interpretations of information and personal experiences. Adolescents assessed the usefulness of information presented to them by examining its relevancy to their own situation, its compatibility with personal beliefs and its consistency with sources identified as credible. Such credible sources might include parents, nurses or teachers.

description: Dynamic features, such as chromospheric jets, transition region network jets, coronal plumes and coronal jets, are abundant in the network regions of the solar polar coronal holes. We investigate the relationship between chromospheric jets and coronal activities (e.g., coronal plumes and jets).We analyze observations of a polar coronal hole including the filtergrams that were taken by the New Vacuum Solar Telescope (NVST) at the Hα-0.6 Åto study the Hα jets,and the Atmospheric Imaging Assembly (AIA) 171 Å images to follow the evolution of coronal activities. Hα jets are persistent in the network regions, only some regions (denoted as R1-R5) are rooted with discernible coronal plumes.With an automated method, we identify and track 1 320 Hα jets in the network regions. We find that the average lifetime, height and ascending speed of the Hα jets are 75.38 s, 2.67 Mm, 65.60 km s$^{-1}$, respectively. The Hα jets rooted in R1-R5 are higher and faster than those in the others. We also find that propagating disturbances (PDs) in coronal plumes have a close connection with the Hα jets. The speeds of 28 out of 29 Hα jets associated with PDs are about 50 km s$^{-1}$ . In a case of coronal jet, we find that the speeds of both the coronal jet and the Hα jet are over 150 km s$^{-1}$, suggesting that both cool and hot jets can be coupled together. Based on our analyses, it is evident that more dynamic Hα jets could release the energies to the corona, which might be the results of the development of Kelvin-Helmholtz instability (KHi) or small-scaled magnetic activities. We suggest that chromospheric jets, transition region network jets and ray-like features in the corona are coherent phenomena, and they are important tunnels for cycling energy and mass in the solar atmosphere.

description: Perhaps the most exciting promise of the Rubin Observatory Legacy Survey of Space and Time (LSST) is its capability to discover phenomena never before seen or predicted from theory: true astrophysical novelties, but the ability of LSST to make these discoveries will depend on the survey strategy. Evaluating candidate strategies for true novelties is a challenge both practically and conceptually: unlike traditional astrophysical tracers like supernovae or exoplanets, for anomalous objects the template signal is by definition unknown. We present our approach to solve this problem, by assessing survey completeness in a phase space defined by object color, flux (and their evolution), and considering the volume explored by integrating metrics within this space with the observation depth, survey footprint, and stellar density. With these metrics, we explore recent simulations of the Rubin LSST observing strategy across the entire observed footprint and in specific regions in the Local Volume: the Galactic Plane and Magellanic Clouds. Under our metrics, observing strategies with greater diversity of exposures and time gaps tend to be more sensitive to genuinely new phenomena, particularly over time-gap ranges left relatively unexplored by previous surveys. To assist the community, we have made all the tools developed publicly available. Extension of the scheme to include proper motions and the detection of associations or populations of interest, will be communicated in paper II of this series. This paper was written with the support of the Vera C. Rubin LSST Transients and Variable Stars and Stars, Milky Way, Local Volume Science Collaborations.

description: Surface charges of a $p$-form theory on the boundary of an AdS$_{d+1}$ spacetime are computed. Counter-terms on the boundary produce divergent corner-terms which holographically renormalize the symplectic form. Different choices of boundary conditions lead to various expressions for the charges and the associated fluxes. With the usual standard AdS boundary conditions, there are conserved zero-mode charges. Moreover, we explore two leaky boundary conditions which admit an infinite number of charges forming an Abelian algebra and non-vanishing flux. Finally, we discuss magnetic $p$-form charges and electric/magnetic duality.

description: The Fat Link Irrelevant Clover (FLIC) fermion action is a variant of the $O(a)$-improved Wilson action where the irrelevant operators are constructed using smeared links. While the use of such smearing allows for the use of highly improved definitions of the field strength tensor $F_{μν},$ we show that the standard 1-loop clover term with a mean field improved coefficient $c_{\rm sw}$ is sufficient to remove the $O(a)$ errors, avoiding the need for non-perturbative tuning. This result enables efficient dynamical simulations in QCD with the FLIC fermion action.

description: The objective of this study was to assess, in a sample composed by postmenopausal women, the agreement between physical activity time reported by short version of the IPAQ and measured by accelerometer in different intensities. The participants consisted of postmenopausal women aged ≥ 50 years (N = 60, mean age 61.5±7.5 years). They completed the IPAQ (short version) and then wore an accelerometer for one week. Statistical analysis was composed by the Kappa index, McNemar’s test, specificity and sensitivity, Spearman’s rank correlation and the Wilcoxon test. The amount of time spent in moderate and vigorous physical activity had weak correlation (r=-0.04-0.28) between accelerometer and IPAQ. IPAQ overestimated the minutes spent in moderate and vigorous intensities and underestimated the time spent in light activities. There was not significant agreement between instruments (kappa index= 0.151±0.111; p= 0.185; sensibility, 46% and specificity, 28%). There was a significant inconsistence for the time of physical activity reported by IPAQ.

description: The review is aimed at highlighting the aspects of topological superconductivity in the absence of spin-orbit interaction in two-dimensional systems with long-range non-collinear spin ordering or magnetic skyrmions. Another purpose is to give a brief introduction to the new concept of topological superconductivity, i.e. higher-order topology in two-dimensional systems including spin-orbit coupled structures. The formation of Majorana modes due to magnetic textures is discussed. The role of effective triplet pairings and odd fermion parity of the ground state wave function in different systems is emphasized. We describe the peculiarities of the magnetic skyrmions, leading to the formation of the Majorana modes and defects on which the modes are localized. The problem of braiding in the two-dimensional systems, especially in higher-order topological superconductors, is considered.

description: Almost every aspect of our daily lives involves liquid-surface interactions and is intimately related to the physicochemical properties of the substrate as well as those of the liquid. Understanding the mechanisms taking place at the initial state of the evaporation process i.e., wettability, and during the evaporation of droplets is of great interest to many industrial, biological, and medical applications. This research investigates experimentally the initial wettability states and the evaporation modes for droplets of pure water, pure ethanol and their binary mixture, accessing a wide range of surface tensions, on hydrophobic and hydrophilic micro-pillared surfaces with fixed height and diameter whilst varying the spacing between the pillars. On one hand, the initial wetting states of pure fluids and their binary mixtures on intrinsically hydrophobic micro-decorated surfaces are first studied and a wetting regime map is proposed. This regime map predicts the droplets’ symmetrical and asymmetrical shapes and wetting dependence on the fluid surface tension and the surface structure on the hydrophobic microstructured surfaces, which in turn govern the subsequent evolution of the droplet contact angle and contact radius. Four different evaporation modes have been observed which are consistent with the literature and further two evaporation modes have been revealed here for the first time, namely, increasing contact angle mixed-sick- slip mode and decreasing contact angle mixed-stick-slip mode. On the other hand, on intrinsically hydrophilic surfaces, the same systematic experimental study is applied using the same fluids and the same microstructured surfaces. It is remarked that the wettability and evaporation on hydrophilic structured surfaces can be affected by ambient exposure after subjecting the surfaces to air plasma cleaning, which eventually removes any deposition of hydrocarbons ever present in the ambient. Unlike the hydrophobic surfaces, the hemi-wicking and spreading regimes are further observed on these surfaces which, consequently, affect the evaporation process. The same six evaporation modes have been observed on these surfaces with different durations though. Investigating the initial wetting and the evaporation modes can lead to a better understanding of choosing the proper structure and wettability (and/or ambient exposure) combined with the correct binary mixture concentration to be specifically tailored to different applications.

description: A sarcopenia é frequentemente observada na pós-menopausa e as causas incluem alterações no estado hormonal e níveis reduzidos de atividade física. Prejuízo funcional e incapacidade física são as principais consequências desta condição. O estudo procurou analisar a associação e o poder discriminatório da atividade física (AF) para a prevenção da sarcopenia em mulheres pós-menopáusicas. A amostra inclui 257 mulheres (57.2 ± 6.6 anos; 69.1± 11.3 kg; 155.0±5,2 cm) e a composição corporal foi medida por bioimpedância. A versão longa do International Physical Activity Questionnaire foi utilizada na apreciação dos níveis de atividade física habitual. A associação das variáveis foi testada através de regressão logística e o poder discriminatório através das curvas Receiver Operating Characteristic, considerando um intervalo de confiança de 95%. A presença de um dispêndio calórico semanal de 580 a 816 kcal através da prática de caminhada revelou poder discriminatório para uma melhor condição muscular na pós-menopausa, sendo registada uma associação significativa entre este tipo de AF e a sarcopenia apenas para o valor de corte de 816 kcal/semana. Os resultados do estudo sugerem que a prática de caminhada, reunindo um dispêndio energético semanal de 816 kcal, previne a sarcopenia em mulheres pós-menopáusicas.

description: O desporto paralímpico encontra-se em processo de afirmação como fenómeno de espetacularização, tendo nos média uma ferramenta de divulgação dos seus ideais e produtos, além de via para potenciais transformações sociais relativas a pessoas com deficiência. O objetivo deste trabalho foi identificar as características e tendências da abordagem mediática ao movimento paralímpico, com base em percepções pessoais de nove atletas paralímpicos portugueses, oito homens e uma mulher, com deficiência visual ou física, todos com experiência internacional nas modalidades desportivas de boccia, natação ou atletismo. A partir de entrevistas semiestruturadas, a análise de resultados pelo método do Discurso do Sujeito Coletivo e a discussão dos dados com base em categorias sociológicas de Pierre Bourdieu, em particular a teoria dos campos, tem-se como principais resultados: i) a divulgação paralímpica ainda é reduzida, tanto em Portugal como em outros países, porém encontra-se em crescimento; ii) os atletas, na sua maioria, preferem a divulgação dos seus feitos desportivos em detrimento do discurso sensacionalista sobre a superação de dificuldades oriundas da condição de deficiência; iii) o desporto paralímpico é desprestigiado em relação ao olímpico. Como principais conclusões encontra-se o descontentamento dos atletas com a reduzida cobertura mediática, com o estigma supercrip e com a supremacia do futebol, tornando-se evidente a manifestação de uma vontade de ocuparem um espaço de maior relevo no campo desportivo, o que lhes conferiria maior legitimidade e possibilidade de desenvolvimento atlético-competitivo, além de ganhos financeiros e sociais.

description: Background: The validity of the Functional Movement Screen (FMS) in identifying active females who are predisposed to injury has not been specifically reviewed. This study aims to synthesize the literature on the ability of the FMS to identify at-risk active females. Methods: Six online databases, including PubMed, Medline, Web of Science, Science Direct, SPORTDiscus and Google Scholar, were searched for the period of April 2006 to September 2021. Out of the 61 potential references, 17 were reviewed in detail with respect to the inclusion criteria; ten were ultimately included. The risk of bias, applicability and level of the studies were then identified using the QUADAS-2 and a checklist for assessing methodological quality. The following data were obtained from the included studies: year of publication, title, study type, participants’ demographic, sample size, FMS cutoff point, injury definition, statistical analyses used, FMS results and study level. Results: Generally, the quality of eight studies was poor to moderate due to both small sample sizes and short follow-up periods. Except for a study on military members, all studies were carried out on team sports players. The overall bias of the studies was low, but there was an unclear amount of bias for participant selection. Two studies reported no predictive validity for the FMS, while three defended its predictive validity; the rest partially supported the FMS as a valid diagnostic tool. The reliability of the recommended cutoff point was confirmed, though cutoffs higher than 14 were significantly associated with the predictive ability of the FMS. Conclusion: Although the FMS is reliable for clinical practice, and the current literature shows promise regarding the predictive ability of the FMS among active females, concerns remain regarding its validity in identifying at-risk females. Given the lack of clarity in the literature on the use of the FMS in females, further well-organized studies with larger sample sizes and longer monitoring periods are highly recommended. The sensitivity and specificity of the recommended cutoff of ≤ 14 has considerably decreased , and higher cutoff values should be applied to increase the FMS predictive ability. Level of evidence: The level of evidence was determined to be 2b.

description: We present an analysis of galaxies in the CDF-South. We find a tight relation to z=3 between color and size at a given mass, with red galaxies being small, and blue galaxies being large. We show that the relation is driven by stellar surface density or inferred velocity dispersion: galaxies with high surface density are red and have low specific star formation rates, and galaxies with low surface density are blue and have high specific star formation rates. Surface density and inferred velocity dispersion are better correlated with specific star formation rate and color than stellar mass. Hence stellar mass by itself is not a good predictor of the star formation history of galaxies. In general, galaxies at a given surface density have higher specific star formation rates at higher redshift. Specifically, galaxies with a surface density of 1-3 10^9 Msun/kpc^2 are "red and dead" at low redshift, approximately 50% are forming stars at z=1, and almost all are forming stars by z=2. This provides direct additional evidence for the late evolution of galaxies onto the red sequence. The sizes of galaxies at a given mass evolve like 1/(1+z)^(0.59 +- 0.10). Hence galaxies undergo significant upsizing in their history. The size evolution is fastest for the highest mass galaxies, and quiescent galaxies. The persistence of the structural relations from z=0 to z=2.5, and the upsizing of galaxies imply that a relation analogous to the Hubble sequence exists out to z=2.5, and possibly beyond. The star forming galaxies at z >= 1.5 are quite different from star forming galaxies at z=0, as they have likely very high gas fractions, and star formation time scales comparable to the orbital time.
