description: Previous studies of the relationship between maternal eating disorders and adverse perinatal outcomes have failed to control for familial transmission of perinatal phenotypes, which may confound the reported association. In a unique design afforded by the Norwegian Mother and Child Cohort Study and Medical Birth Registry of Norway, we linked three generations through birth register records and maternalreported survey data to investigate whether maternal eating disorders increase risk after parsing out the contribution of familial transmission of perinatal phenotypes. The samples were 70,881 pregnancies in grandmother-mother-child triads for analyses concerning eating disorder exposure during pregnancy and 52,348 for analyses concerning lifetime maternal eating disorder exposure. As hypothesized, eating disorders predicted a higher incidence of perinatal complications even after adjusting for grandmaternal perinatal phenotypes. For example, anorexia nervosa immediately prior to pregnancy was associated with smaller birth length (relative risk = 1.62; 95% CI [1.20, 2.14]), bulimia nervosa with induced labor (relative risk = 1.21; 95% CI [1.07, 1.36]), and binge-eating disorder with several delivery complications, larger birth length (relative risk = 1.25; 95% CI [1.17, 1.34]), and large-for-gestational-age (relative risk = 1.04; 95% CI [1.01, 1.06]). Maternal pregravid body mass index and gestational weight mediated most associations. Our results support that exposure to eating disorders increases the risk for negative health outcomes in pregnant women and their babies.

description: We present an exact numerical study of the scaling of density and momentum distribution functions of harmonically trapped one-dimensional bosons with repulsive contact interactions at zero and finite temperatures. We use path integral quantum Monte Carlo with worm updates in our calculations at finite interaction strengths, and the Bose-Fermi mapping in the Tonks-Girardeau regime. We discuss the homogeneous case and, within the local density approximation, use it to motivate the scaling in the presence of a harmonic trap. For the momentum distribution function, we pay special attention to the high momentum tails and their $k^{-4}$ asymptotic behavior.

description: Purpose Disordered eating is more prevalent among adolescents with attention deficit/hyperactivity disorder. Both inattention and hyperactivity/impulsivity symptoms show strong associations with disordered eating, but few investigations of these associations have been longitudinal. Thus, we examined the effect of childhood to adolescent inattention and hyperactivity/impulsivity symptom trajectories on late adolescent disordered eating. Methods We used growth mixture modeling to identify distinct inattention and hyperactivity/impulsivity symptom trajectories (called “classes”) across three time points (ages 8–9, 13–14, and 16–17 years) in the Swedish Twin study of CHild and Adolescent Development. The resulting classes were used to predict Eating Disorder Inventory-2 Bulimia, Drive for Thinness, and Body Dissatisfaction subscales at age 16–17 years, with adjustment for sex and body mass index at age 16–17 years. Results The combined inattention and hyperactivity/impulsivity symptom trajectory classes included: a “low symptom” class characterized by low inattention and hyperactivity/impulsivity throughout childhood/adolescence; a “predominantly inattention” class characterized by elevated inattention, but not hyperactivity/impulsivity, throughout childhood/adolescence; a “predominantly hyp/imp” class characterized by elevated hyperactivity/impulsivity, but not inattention, throughout childhood/adolescence; and a “both inattention and hyp/imp” class characterized by elevated inattention and hyperactivity/impulsivity throughout childhood/adolescence. After adjusting for sex and body mass index or sex and anxiety/depression symptoms, the “both inattention and hyp/imp” (vs. “low symptom”) class predicted significantly higher Eating Disorder Inventory-2 subscale scores during late adolescence. Conclusions Increased vigilance for disordered eating among children who have both inattention and hyperactivity/impulsivity symptoms throughout childhood and adolescence could aid in early identification of eating disorders.

Multi-dimensional percolation
European urban system
Mega-city region

description: Network percolation has recently been proposed as a method to characterize the hierarchical structure of an urban system form the bottom-up. This paper proposes to extend urban network percolation in a multi-dimensional way, to take into account both urban form (spatial distribution of population) and urban functions (here as properties of transportation networks). The method is applied to the European urban system to reconstruct endogenous urban regions. The variable parametrization allows to consider patterns of optimization for two stylized contradictory sustainability indicators (economic performance and greenhouse gases emissions). This suggests a customizable spatial design of policies to develop sustainable territories.

description: Objective: This paper compared Latinas who self-identified as having had an eating disorder (ED) with those who did not (despite both groups meeting criteria for an ED history) on ED pathology and mental health stigma. Method: Seventy-seven Latinas completed an online survey. Results: All 77 participants met criteria for lifetime EDs, and 92% met current criteria for an ED; however, 47% did not report having an ED history vs. 53% did report an ED history. There was no difference on binge eating frequency. Those who endorsed an ED history engaged in more compensatory behaviors, had higher EAT-26 scores, and were less fearful of stigmatization due to seeking mental health treatment. Those reporting an ED history were more likely to have met criteria for anorexia nervosa or bulimia nervosa, generally more recognizable EDs than binge eating disorder and other specified feeding or eating disorders, than those who did not report an ED history. Discussion: Latinas with certain patterns of eating pathology and those with less fear of being stigmatized due to seeking mental health treatment were more likely to endorse an ED history, which has implications for treatment seeking.

description: Palomar 5 (Pal 5) is a faint halo globular cluster associated with narrow tidal tails. It is a useful system to understand the process of tidal dissolution, as well as to constrain the potential of the Milky Way. A well-determined orbit for Pal 5 would enable detailed study of these open questions. We present here the first CCD-based proper motion measurement of Pal 5 obtained using SDSS as a first epoch and new LBT/LBC images as a second, giving a baseline of 15 years. We perform relative astrometry, using SDSS as a distortion-free reference, and images of the cluster and also of the Pal 5 stream for the derivation of the distortion correction for LBC. The reference frame is made up of background galaxies. We correct for differential chromatic refraction using relations obtained from SDSS colors as well as from flux-calibrated spectra, finding that the correction relations for stars and for galaxies are different. We obtain mu_alpha=-2.296+/-0.186 mas/yr and mu_delta=-2.257+/-0.181 mas/yr for the proper motion of Pal 5. We use this motion, and the publicly available code galpy, to model the disruption of Pal 5 in different Milky Way models consisting of a bulge, a disk and a spherical dark matter halo. Our fits to the observed stream properties (streak and radial velocity gradient) result in a preference for a relatively large Pal 5 distance of around 24 kpc. A slightly larger absolute proper motion than what we measure also results in better matches but the best solutions need a change in distance. We find that a spherical Milky Way model, with V_0=220 km/s and V_(20 kpc), i.e., approximately at the apocenter of Pal 5, of 218 km/s, can match the data well, at least for our choice of disk and bulge parametrization.

description: O processo de formação esportiva de jovens em desenvolvimento apresenta uma natureza não linear. Logo, considerando as variedades de condições existentes, esse processo deve ser pensado em longo prazo. Pensando nisso, entender como um clube de natação competitiva conduz o treinamento em longo prazo de seus nadadores é importante para analisar diversos aspectos que envolvem essa preparação. O nosso objetivo foi investigar se o processo de formação dos nadadores competitivos em clubes da cidade do Rio de Janeiro está de acordo com os fatores biopsicossociais que norteiam o treinamento em longo prazo. Para realização da pesquisa foi elaborado um questionário de característica quali-quantitativa e distribuído para cinco treinadores chefes de natação de clubes do cenário competitivo da cidade do Rio de Janeiro. Estes, por meio da escala Likert, demonstraram o nível de concordância a algumas afirmações acerca do processo de formação competitiva. Dessa maneira, foi traçada a filosofia do clube para a formação de um jovem nadador. Encontrou-se que 20% dos clubes sempre interagem o treinamento da natação como de outros esportes aquáticos, 60% dos clubes sempre flexibilizam o planejamento do treinamento devido à diferença de maturação física entre os atletas, 20% dos clubes sempre flexibilizam o planejamento do treinamento devido às necessidades sociais dos atletas e 20% dos clubes sempre flexibilizam o planejamento do treinamento devido às necessidades emocionais dos atletas. Concluiu-se que os clubes avaliados precisam de alguns ajustes no que se refere à interação entre os esportes aquáticos no período da iniciação esportiva, ao início do treinamento da força muscular e a ampliação do monitoramento e da avaliação para protocolos que mensurem a maturação, o crescimento e o emocional dos jovens atletas, visando atender ao que é prescrito na literatura especializada.

description: Positron emission tomographs (PET) do not measure an image directly. Instead, they measure at the boundary of the field-of-view (FOV) of PET tomograph a sinogram that consists of measurements of the sums of all the counts along the lines connecting two detectors. As there is a multitude of detectors build-in typical PET tomograph structure, there are many possible detector pairs that pertain to the measurement. The problem is how to turn this measurement into an image (this is called imaging). Decisive improvement in PET image quality was reached with the introduction of iterative reconstruction techniques. This stage was reached already twenty years ago (with the advent of new powerful computing processors). However, three dimensional (3D) imaging remains still a challenge. The purpose of the image reconstruction algorithm is to process this imperfect count data for a large number (many millions) of lines-of-responce (LOR) and millions of detected photons to produce an image showing the distribution of the labeled molecules in space.

description: Objective We examined the association between the genetic and environmental factors contributing to the liability to having ever engaged in self-induced vomiting (SIV initiation) and the genetic and environmental factors contributing to regular SIV behaviors (weekly or daily) for weight control. Method SIV was assessed in 3,942 women from monozygotic twin pairs and 2,790 women from same-sex dizygotic twin pairs, aged 20-47, from the Swedish Twin study of Adults: Genes and Environment. A causal-contingent-common pathway model assessed the extent to which genetic and environmental factors that influence initiation of SIV also influence regular SIV behaviors. Results In the best-fit model, genetic and individual-specific environmental factors influenced liability to SIV initiation. The genetic factors influencing regular SIV behaviors were the same as the genetic factors influencing SIV initiation. Additional individual-specific environmental factors that were unrelated to SIV initiation influenced regular SIV behaviors. Discussion Our findings provide evidence that the underlying liabilities for SIV initiation and regular SIV lie on the same continuum given the degree of overlap in risk between SIV initiation and regular SIV behaviors. Further, the lack of specific genetic factors and the importance of individual-specific environmental factors for regular SIV behaviors highlight the significance of environmental factors in the etiology of eating disorder symptomatology and the non-deterministic nature of genetic factors. Finally, our results suggest that when it comes to preventing individuals from developing regular SIV behavior, intervening at an environmental level is warranted.

description: The aim of this study was to develop fotonovelas, a popular type of graphic novel in the Latino population, to raise awareness and educate about eating disorders (EDs). Four illustrated cartoons and scripts tailored for adults and adolescents of both sexes were presented in focus groups and an in-depth interview. Seventeen Latino adults (14 females; 3 males) and 10 adolescents (9 females; 1 male) participated in the study. Participants found the fotonovelas interesting, and eye-catching than traditional brochures. The use of Spanglish and clarification of differences across EDs were suggested by adolescent females. Male adults suggested changing the title to focus on the health consequences of EDs in order to catch the male attention in reading the story. Based on the receptivity we found in this study, fotonovela could be a promising avenue to raise awareness and to educate the Latino community in the United States about EDs.

description: Os exercícios em plataformas instáveis têm sido utilizados cada vez mais por parte da indústria do fitness de forma a promover diferentes estímulos musculares. Deste modo, o objetivo deste estudo consistiu em comparar a atividade muscular, analisando as diferenças existentes entre os exercícios no solo e na plataforma à superfície da água, com e sem turbulência. A amostra foi composta por 12 indivíduos (sete homens e cinco mulheres) que realizavam prática desportiva regular (idades: 20,08± 0,95 anos; massa corporal: 64,86± 8,30 kg; altura: 1,70± 0,08 m). Cada indivíduo realizou durante 10 segundos exercícios de agachamento (dinâmico e isométrico) e de prancha (de cotovelos e de mãos) no meio terrestre e no meio aquático com e sem turbulência, com um intervalo de 40 segundos entre cada exercício. Foram analisados cinco músculos: reto femoral, bicípete femoral, eretor espinhal externo, oblíquo externo e reto abdominal, através de eletromiografia de superfície (bioPlux research, Portugal). Foram encontradas diferenças estatisticamente significativas entre a ativação de cada um dos músculos considerados no meio terrestre e no meio aquático com turbulência, com exceção do reto abdominal. Desta forma, verificou-se o aumento gradual do recrutamento muscular em função do aumento da instabilidade do meio, sendo substancialmente superior na condição “com turbulência”. Os nossos resultados indicam que a realização dos exercícios de agachamento (dinâmico e isométrico) e prancha (de cotovelos e mãos) no meio aquático revela-se mais intensa para os participantes, aumentando a ativação muscular dos músculos reto femoral, bicípete femoral, erector espinhal externo e oblíquo externo, essencialmente se lhes for aplicada turbulência em ambos lados. Logo, podemos concluir que a realização destes exercícios em meio instável em condição de aula aumenta significativamente o recrutamento muscular. Desta forma, os técnicos de exercício, caso pretendam aumentar a intensidade dos exercícios realizados, devem privilegiar a condição de instabilidade.

description: Na natação pura desportiva, a técnica assume um papel de elevada importância, dada a sua influência sobre a economia de nado. Os clubes necessitam, por tal, de suportar estratégias que facilitem a tarefa de avaliação dos treinadores e o reconhecimento dos nadadores dos padrões de movimento a alterar. O Clube Colégio de Lamas construiu um dispositivo de recolha de imagem que consiste num carril sobre o qual é colocado um charriot que tem acopladas duas câmaras de vídeo (GoPro Hero4) verticalmente alinhadas e que recolhem simultaneamente, durante o nado, imagens de superfície e subaquáticas. Dez nadadores do escalão Juvenis, cinco rapazes e cinco raparigas (15,1± 0,7 anos, 167,7± 9 cm e 59,6± 6,2 kg), foram avaliados na técnica preferida e à velocidade média correspondente à melhor distância de nado, em nove momentos ao longo da presente época desportiva. O dispositivo construído permitiu recolher imagens de forma facilitada por ser apenas necessário mover o charriot sobre o carril para acompanhar o nado. As imagens foram utilizadas para identificar e mostrar aos nadadores os erros técnicos e comparadas com imagens de nadadores de elevada performance obtidas na internet. Posteriormente, nos exercícios destinados ao treino técnico, foi pedido aos nadadores que se focassem nos erros identificados e que os tentassem corrigir, recebendo feedback constante do treinador durante a execução. A evolução da técnica de nado encontra-se reportada no Quadro 1. A utilização de imagens de superfície e subaquáticas recolhidas pelo treinador no plano sagital com recurso ao charriot revelou ser uma ótima ferramenta na orientação do treino da técnica dos nadadores, que, por sua vez, sentiram ser mais fácil corrigir a técnica ao verem em vídeo os erros que cometiam, comparativamente com a habitual correção verbal e gestual realizada pelo treinador.

description: This preliminary study surveyed the feeding practices of mothers with eating disorder histories through evaluation of mothers' reported feeding styles, child diet composition and restrictive special approaches to feeding. For this non-randomised cohort study, 25 mothers with eating disorder histories and 25 mothers with no history of an eating disorder with children ages 6-36 months were selected such that the groups were similar based on child age group and child sex. Mothers were compared on self-reported feeding style using the Infant Feeding Styles Questionnaire and on child diet composition and special feeding approaches using a modified version of the Toddler Diet Questionnaire from the Women, Infants, and Children program. Mothers with eating disorder histories scored lower on the restrictive feeding style subscale than controls. No significant differences were detected between groups in child diet including the percentage of mothers who breastfed, duration of breastfeeding, age at solid food introduction, daily number of meals or snacks or daily frequency of consumption of fruits, vegetables or protein foods. Mothers with eating disorder histories were more likely to report taking a restrictive special approach to feeding such as limiting processed foods or feeding organic foods only. Although mothers with eating disorder histories may not differ greatly from control mothers in terms of child diet composition (smaller effects may not have been detected due to limited sample size), they may be more likely to take restrictive special approaches to feeding which mirror dietary rules common in individuals with eating disorders.

description: We consider the two mainstream cosmological models that can be derived from the two physical theories that are the best verified by experiments: general relativity and quantum mechanics, though they are incompatible and a major challenge in physics is to find how to reconcile them. The first model is the block universe, which is considered today as the best way to represent our space-time, if we accept all consequences of general relativity, which seem to imply in particular that our future is already realized and cannot change. The second is the Everett multiverse model, whose most popular interpretation is that it contains all alternative possibilities to conduct our life at our human level (with as many copies of our individual consciousness). Our purpose in this article is to show that the incompatibility between the two mainstream theories could be solved in its global principle via a cybernetical conception of time, through which the block universe would be made flexible. For this purpose we show that the 6 extra dimensions of space-time we introduced in a previous paper [16] could be used to coordinate space-time from its outside, so as to make it evolve in the cybernetical time from a 4D structure to any other one belonging to a 10D multiverse. We propose this coordination to be modeled thanks to a 3 layers neural network toy model, using two additional layers corresponding to the necessity to parametrize the choices of paths and destinations so as to restore determinism. The main interest of this approach is to maintain the possibility of a relative free will in our universe.

description: A presente época desportiva caracterizou-se pela interrupção compulsiva do treino ocasionada pelas medidas governamentais de combate à COVID-19, pelo que se presumiu improvável a esperada evolução do rendimento. Com um planeamento bem estruturado e adaptado a nadadores masters (n= 4), suportado na avaliação da velocidade crítica (utilizando repetições máximas de 200 e 800 m crol), foi possível superar o destreino e melhorar o rendimento. A época foi dividida em dois macrociclos, o primeiro comportando as fases de preparação geral e específica (oito semanas cada), mas não se realizando o período competitivo (tendo-se-lhe seguido 11 semanas de paragem). O segundo macrociclo caracterizou-se por uma etapa de preparação geral de seis semanas (com aumento progressivo da carga de treino, utilizando um modelo de exposição à carga em formato de escada direcionada para o trabalho aeróbio extensivo), uma etapa de preparação específica de sete semanas (direcionada para a melhoria da resposta bioenergética específica e da proficiência técnica), um período competitivo de uma semana (com diminuição do volume e da intensidade absoluta e centrado na utilização de métodos competitivos) e um período de transição de três semanas (com diminuição da carga de treino e aumento da diversidade de estímulos motores aquáticos). O segundo macrociclo foi planeado com uma estrutura muito semelhante à do anterior, uma vez que no primeiro teste de avaliação e controlo do treino, realizado na quarta semana do período de preparação geral, o valor da velocidade crítica estava ainda abaixo do último valor obtido antes do confinamento (0,89± 0,14 vs. 0,94± 0,13 m.s-1). A reversão para valor semelhante (0,93± 0,12 m.s-1) ocorreu apenas à oitava semana de treino, já durante a etapa de preparação específica. Quatro semanas adicionais de potência glicolítica e tolerância lática permitiram que os resultados do Open de Verão fossem superiores aos estimados a partir do desempenho em treino. Espera-se que a informação exposta possa ser útil para racionalizar e objetivar processos de treino que decorram em condições semelhantes.

description: Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work we report on a fitting technique used to account for different detector responses resulting from photo absorption in the various APD layers. The use of this technique results in an improvement of the energy resolution at 8.2 keV by up to a factor of 2, and corrects the timing information by up to 25 ns to account for space dependent electron drift time. In addition, this waveform analysis is used for particle identification, e.g. to distinguish between x-rays and MeV electrons in our experiment.

 Features: Length 90–130 μm, width 6–12 μm, fibulae 8–12 in 10 μm, striae 22–28 in 10 μm.
 Description: valves linear to linear lanceolate, slightly sigmoid, with curving acute apices. Raphe eccentric, fibulae small, equally spaced.
 Remarks: Several varieties of N. sigma were described based on striae density and whether valves (in valve view) are sigmoid or straight. It is sometimes difficult to identify these varieties and some of them might belong to a different species, which requires further investigation of this complex using SEM diagnosis or molecular data. Striae density is rather variable and in some specimens, these are hardly counted under light microscope.
 Ecology and Distribution: A widely distributed species in marine and brackish water habitats. Previously reported from the Gulf (Hendey 1970, Al-Yamani & Saburova 2011, Al-Handal 2011). Common in Basra corals.

description: The enigmatic question of time, essentially of a physical, psychological and social nature, occupied human since becoming aware of his existence and of the surrounding environment. Students' conceptions may be the starting point for improving their understanding of the world. These conceptions play a decisive role throughout learning procedure and are often incompatible with the scientific model. Conceptions’ analysis is a tool for the advancement of a proximal development zone in which a first conceptual system can be built by students. This paper presents findings on 5 to 7-year-old students’ conceptions about the inverse relationship between time and speed.

description: Background Screening criteria have been used to estimate the prevalence of night eating syndrome (NES), but no validation studies have been conducted. Method We examined the validity of two screening questions for NES using a structured interview with adults enrolled in the Swedish Twin Study of Adults: Genes and Environment (STAGE) study. We also examined the coherence of the proposed diagnostic criteria for NES. A total of 416 participants (men = 179; women = 237) completed the interview and reported complete data for study inclusion. Results The following values were calculated for the screening items after confirmation by interview for men and women, respectively: Positive predictive value =.66 and.67, negative predictive value =.52 and.45, sensitivity =.62 and.63, and specificity =.56 and.50. As increasingly stringent diagnostic criteria were applied to the sample, prevalence of NES dropped. Nocturnal ingestions were more likely to co-occur with other NES symptoms than evening hyperphagia, which occurred frequently, but often in isolation; women were more likely to report a co-occurrence of symptoms than men, who were not likely to report distress related to NES symptoms. Conclusion In sum, almost two-thirds of participants were correctly identified as having NES (without considering distress or impairment) if they answered positively on the screening questions, and about half of the participants were correctly identified as not having NES when answering negatively on the screening questions. Although self-report questions are somewhat informative, a structured interview remains the gold standard for diagnosing NES.
