description: The handed down latitudinal data ascribed to Eratosthenes and Hipparchus are composed and each tested for consistency by means of adjustment theory. For detected inconsistencies new explanations are given concerning the origin of the data. Several inconsistent data can be ascribed to Strabo. Differences in Hipparchus' data can often be explained by the different types and precision of the data. Gross errors in Eratosthenes' data are explained by their origination from the lengths of sea routes. From Eratosthenes' data concerning Thule a numerical value for Eratosthenes' obliquity of the ecliptic is deduced.

description: The dog (Canis lupus familiaris) was the first species to be domesticated from the wolf. Since its domestication, it has undergone thousands of years of selective breeding, contributing to a myriad of phenotypic/behaviour variants. Most modern dog breeds are 200 years old and are of European ancestry. In Iberia, there are 21 internationally recognized dog breeds, including local varieties within breeds. In this talk, I will summarize the main aims of my research, the zooarchaeogenomic approaches employed and the results of an ongoing project dedicated to the understanding of the origins and evolution of this species in Iberia and the Maghreb regions. My team gathered temporally spaced archaeological samples identified as dogs covering periods since the Mesolithic (~8,000 years ago in Iberia). Our multidisciplinary research involves the analysis of each sample by different approaches: genomic, zooarchaeological (archaeological context, odontometry, osteometry), isotope, radiographic and pathology analysis. In samples with sufficient endogenous content (e.g. >1%), we perform whole-genome analyses in addition to that of mitogenomes using high-throughput resequencing methods. Our results show evidence of early morphological diversification, at least since the Chalcolithic (4,000-5,000 years ago), and the presence of distinct maternal lineages of the major haplogroups A and C. We also verify the replacement of some ancient mitogenomic diversity over time. My team is very much committed to communicate scientific findings to broad audiences, therefore we frequently participate in outreach activities directed to the general public and schools.

description: Introduction: Of all age groups in the United States, young adults have some of the poorest sexual and reproductive health outcomes. There are numerous factors that account for this phenomenon – one of which is lack of high-quality communication between young adult patients and providers of sexual and reproductive health care. The objective of this study was to gain feedback from focus groups: (a) about barriers and facilitators to communication surrounding sexual health and (b) the feasibility and acceptability of the question prompt list and informational video as tools of patient empowerment via education and question-asking during medical visits.

Methods: A total of three focus groups were conducted: two with patients (n =14) and one with providers (n = 5) of sexual and reproductive health care services for young adults. Young adult participants were aged 18-22 years old. Provider participants were recruited from healthcare clinics. 

Results: Participants identified several barriers to communication including feelings of embarrassment and assumptions about patients’ knowledge. One facilitator of communication identified was patient-friendly language. Focus group participants offered various suggestions on how to improve the question prompt list and the video, as well as themes that should be covered in the educational video. The question prompt list and educational video were also viewed as useful for encouraging conversation between patient and provider. 

Conclusions: There are many barriers that prevent optimal communication between young adult patient and their providers when discussing sexual health. Several improvements to the question prompt list and educational video were identified in this study. It was determined that both the question prompt list and educational video can be used to enhance patient-provider communication.

description: There is a need to shift the research culture and embrace collaborative partnerships, involving multiple teams with complementary expertise. Anatomical examination of animal bones found at archaeological sites may provide information regarding species, age and sex identification and find evidence of past animal use. Additionally, animal remains may help reconstruct prehistoric human-animal relations and deduce our past behaviors. The ongoing CRIAS project was developed to diminish the lack of information in veterinary and zooarchaeological literature as far as neonatal/young-aged pig skeleton development. Based on bone analysis, radiographic and CT images of Sus scrofa domesticus at 12 weeks, our team has fully described the ossification centers of long bones, as well as diaphysis measurements. These data, not only have improved anatomical and clinical knowledge of this species, but also enhanced zooarchaeological knowledge about the bones of young Sus specimens which sometimes are found in archaeological contexts and are difficult to identify. Contrary to adult specimens, the underdeveloped or even absent skeletal landmarks in newborns and juveniles may impair their species identification. This research has also contributed to benefit society by improving animal health and welfare, while at the same time providing our students with better educational resources, taking into account their future activity on a wide range of relevant areas of the Veterinary profession. Moreover, a novel close collaboration with an external entity - the Laboratório de Arqueociências (DGPC) was created, which brings advantages for the development of additional studies in the Veterinary and Zooarchaeological sciences hybrid area. Keywords: juvenile pig anatomy, skeleton development, reference osteological collections, zooarchaeology, collaborative research. Financing: ULHT-FMV - projecto exploratório 2021 – CRIAS.

description: The global increase of veterinary students, the growing demands for high standards in educational quality, and the biosecurity and physical risks have led many veterinary education establishments to use models to simulate clinical procedures. Traditionally, teaching clinical areas of medicine starts with the explanation of fundamental theoretical concepts, followed by application in a real clinical context using live animals. Large numbers of students may interfere with animal welfare, decrease the opportunity for direct animal contact and diminish educational quality. Model simulation allows "learning by doing" and the development of practical skills in scenarios that resemble reality, without the need for live animals, and therefore brings safety and practical training regardless of the number of students. To date, there is no bovine abdominal surgery simulator commercially available. This work aims to develop a bovine abdominal surgery model simulator that supports practical training and to evaluate how this model can positively impact the learning process of veterinary students. The project is a ULHT transdisciplinary work of professors, technicians, and students from Veterinary Medicine, Computer Science, and Imaging. We will generate all the digital data needed for 3D printing of the model components, and the simulator will have materials of variable flexibility. In 2023/24, the model will be used in PCC II and CEP I classes. A questionnaire will assess teachers and students’ perception of the pedagogical experience using the model simulator, and practical tests will determine the level of clinical knowledge and skills acquisition.

description: For TOSCA to move forward beyond the current state-of-the-art in key scientific areas such as gas and charge storage, the most urgent need is for greater sensitivity via the secondary spectrometer upgrade that would make TOSCA competitive with other similar instruments, such as VISION at the SNS, in terms of total count rate. The here proposed upgrades can improve the collection efficiency of the neutrons scattered from the sample and the effects in terms of resolution have to be evaluated alongside. This document is focused on the design of a TOSCA doubly bent analyzer by means of McStas suite, which currently does not implement a component that can simulate a curved monochromator along multiple axes. Therefore, to proceed with the simulation of the secondary spectrometer, we had to create a custom component which can meet the TOSCA needs. We used several Highly Oriented Pyrolytic Graphite (HOPG) tiles arranged on a parametric surface up to an area of 1450 cm2 that can have two different curvatures, spherical and parabolic. Several simulations have been performed with this component to study the performance of the current and future TOSCA setup at the elastic line. Graphite analyzers with different areas and radii of curvature have been considered and each parameter has been optimized via computational analysis. From the simulations, we found that with the appropriate focusing, it is possible to increase the current analyzer area by tenfold reaching a flux gain of 7. It is also evident that for larger analyzers the parabolic geometry outperforms the spherical one thanks to its better focusing properties. The calculations also show that this gain is achieved with limited effects on resolution, provided that an extensive optimization is performed on the parameters of curved geometry. The geometric optimization in this study has been computationally implemented using MATLAB routines in conjunction with McStas.
Viscoelastic fluid flow in a 2D channel bounded above by a deformable finite thickness elastic wall

description: The steady flow of three viscoelastic fluids (Oldroyd-B, FENE-P, and Owens model for blood) in a two-dimensional channel, partly bound by a deformable, finite thickness neo-Hookean solid, is computed. The limiting Weissenberg number beyond which computations fail to converge is found to increase with increasing dimensionless solid elasticity parameter Γ, following the trend Owens > FENE- P > Oldroyd-B. The highly shear thinning nature of Owens model leads to the elastic solid always collapsing into the channel, for the wide range of values of Γ considered here. In the case of the FENE-P and Oldroyd-B models, however, the fluid-solid interface can be either within the channel, or bulge outwards, depending on the value of Γ. This behaviour differs considerably from predictions of earlier models that treat the deformable solid as a zero-thickness membrane, in which case the membrane always lies within the channel. The capacity of the solid wall to support both pressure and shear stress, in contrast to the zero-thickness membrane that only responds to pressure, is responsible for the observed difference. Compar- ison of the stress and velocity fields in the channel for the three viscoelastic fluids, with the predictions for a Newtonian fluid, reveals that shear thinning rather than elasticity is the key source of the observed differences in behaviour.

Representations of the Bannai-Ito algebra are constructed using ladder operators. Eigenfunctions of the spherical Dirac-Dunkl operator are obtained using a Cauchy-Kovalevskaia extension theorem. These eigenfunctions, which correspond to Dunkl monogenics, are seen to support finite-dimensional irreducible representations of the Bannai-Ito algebra.

description: O Núcleo de Investigação Veterinária em Imagiologia, Cirurgia e Oncologia (NIVICO) da FMV-ULHT, foi criado no início de 2022 para dar resposta às linhas de investigação que existem nestes três serviços no Hospital Escolar de Animais de Companhia e que frequentemente se cruzam e estão intimamente ligadas. O serviço de oncologia frequentemente recorre à cirurgia oncológica durante a abordagem terapêutica dos seus pacientes, e foi neste âmbito que se criou a primeira linha de investigação, o estudo da utilização de citologia intraoperatória para confirmar a presença de margens cirúrgicas limpas em cirurgias oncológicas. Assim, e após o estadiamento oncológico que requer a colaboração do serviço de imagem, pretende-se conseguir garantir margens cirúrgicas adequados que melhorem o prognostico do paciente oncológico. A oncologia e imagiologia cruzam-se de novo através do estudo de linfoangiografia por tomografia computorizada indirecta, onde se pretende estudar a possibilidade de indentificar linfonodos sentinelas de neoplasias cutâneas e orais, para que possam ser posteriormente removidos cirurgicamente. Na última linha de investigação a ser apresentada pelo núcleo, estuda-se a aplicabilidade de radiografias mediolaterais descentradas para avaliação das articulações tempromandibulares sem ter de recorrer a tomografia computorizada, identificando casos onde o mesmo será benéfico para o maneio do caso. Assim, o NIVICO pretende evidenciar através de projetos de investigação a interdependência da cirurgia, oncologia e imagiologia, dinamizando estes serviços no HE-AC da FMV, convidando colegas e alunos a participarem nesta equipa.

description: No crescimento, desenvolvimento e homeostasia dos seres multicelulares as suas células devem comunicar entre si eficientemente. Entre as várias estratégias possíveis, a via de comunicação intercelular Notch é uma das mais bem conservadas entre os metazoários. Notch está frequentemente implicada na regulação da diferenciação/proliferação celulares, sendo as suas ações específicas da célula em causa, do tecido onde se encontra e da fase de desenvolvimento do animal. Assim, a sua presença e atividade pode variar de acordo com os vários processos fisiológicos e patológicos de uma dada espécie. A regulação do desenvolvimento embrionário não é totalmente conhecida. A primeira autora desenvolveu estudos sobre a implicação da Notch na primeira diferenciação celular (de mórula para blastocisto), caracterizando a presença das proteínas que compõem Notch e a transcrição dos mRNA que lhes dão origem foi avaliada em embriões individuais –conjuntos de 70 células (no máximo) com forma esférica. Verificou-se que Notch é importante nesta fase, controlando o ritmo do desenvolvimento através do controlo de vários marcadores de pluripotência/diferenciação. Uma das características de processos neoplásicos é a incapacidade das células regularem o seu crescimento/diferenciação e Notch tem sido implicada nesta desregulação em humanos, incluindo em carcinomas das células escamosas. Num estudo da FMV-ULHT, constatou-se que esta é uma neoplasia comum em gatos em Portugal, sabendo-se também que diminui a sua qualidade de vida, implicando amiúde a eutanásia. Neste sentido iniciou-se um projeto de investigação exploratório para averiguar a presença da Notch nestes tumores e a sua relação com critérios de malignidade. Esta será a base para futuramente desenhar terapêuticas inovadoras dirigidas e eficazes, potencialmente transversais a Medicina Veterinária e Humana.

description: Frozen transient imbibition states into two complementary pore models having pore diameters of ~380 nm and hydroxyl-terminated inorganic-oxidic pore walls, controlled porous glass (CPG) and self-ordered porous alumina (AAO), were imaged by phase-contrast X-ray computed tomography (X-ray CT), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy mapping (EDX). The deployment of phase-contrast X-ray CT bring together the advantages of macroscopic averaging methods and microscopy by allowing the algorithmic evaluation of three-dimensional reconstructions of imbibition morphologies to study characteristic features with characteristic length scales in the range from a few tens of μm down to the sub-μm scale, not possible with averaging methods, and with high validity, unattainable with microscopy. CPG contains continuous spongy-tortuous pore systems. AAO containing arrays of isolated straight cylindrical pores is a reference pore model with a tortuosity close to 1. Comparative evaluation of the spatiotemporal imbibition front evolution yields important information on the pore morphology of a probed tortuous matrix like CPG and on the imbibition mechanism. Image analysis methods based on the evaluation of pixel brightness fluctuations were developed to determine imbibition front positions and widths by descriptive statistics. The retardation of the imbibition front movement with respect to AAO reference samples may be used as a descriptor for the geometric tortuosity of a tested porous matrix. The velocity of the imbibition front movements in CPG equaled two-thirds of the velocity of the imbibition front movements in AAO. Moreover, the dynamics of the imbibition front broadening discloses whether porous matrices are dominated by cylindrical neck-like pore segments or by nodes. Independent single-meniscus movements in cylindrical AAO pores result in faster imbibition front broadening than in CPG, in which a morphology dominated by nodes results in slower cooperative imbibition front movements involving several menisci. The results presented here may be relevant to a broad variety of applications including printing, adhesive bonding, oil recovery, water filtration, as well as the optimization of production and properties of engineering, construction and hybrid materials.

description: A transdisciplinary health perspective of ARV pathways
in an informal settlement

Background: South Africa has
one of the largest antiretroviral (ARV) consumer markets, globally. When traces
of ARVs surfaced in South African water sources, scientists from environmental
sciences collaborated with health – and social sciences to explore this
phenomenon. The intersectionality of HIV implied that ARVs in water would be
best understood from a holistic perspective.

Aim: To describe a transdisciplinary
health perspective of the possible ARV pathways presented in a typical
Gauteng-based informal settlement.

Methods: A
qualitative, explorative, descriptive and contextual design was followed
through an integrated literature review. Data were collected between February
and March 2017 (N-52).

Results:
Four major pathways
were presented and a conceptual framework depicted. The first pathway presents
the distribution of ARVs through South African health systems. This pathway
explained ARV value chains within primary health care (PHC). The second pathway
is the biological perspectives of ARV from consumption to excretion. The third
pathway denotes ARVs within the psychosocial realities of living in an informal
settlement. The fourth pathway consider the risks of improper ARV disposal
practices and ARVs filtering into the natural resources.

description: Os mastocitomas são as neoplasias malignas de pele mais comuns nos cães. O diagnóstico é direto, contudo o seu comportamento biológico é imprevisível. Até ao momento continua a não existir uma metodologia capaz de sinalizar todos os mastocitomas mais agressivos. A linha de investigação do nosso laboratório e tema de projeto de doutoramento foca-se na avaliação do potencial prognóstico de diferentes técnicas e marcadores biológicos nos mastocitomas dos cães. As tarefas que se encontram a ser desenvolvidas são: Um estudo epidemiológico, cujo objetivo é o de sinalizar fatores de risco no desenvolvimento deste tumor e no qual estão incluídos 851 mastocitomas diagnosticados entre 2020-2021. Um estudo de follow-up clínico no qual foi avaliado o outcome em 60 casos de mastocitomas diagnosticados entre 2017-2022, de modo a ser obtido um conjunto de amostras com informação sobre o comportamento biológico. A avaliação de marcadores de prognóstico nos casos com follow-up, nomeadamente a avaliação expressão tecidular da Cicloxigenase-2 (COX2), a pesquisa de mutações no gene CKIT e a medição do volume médio nuclear. A avaliação da expressão da COX2 está a ser realizada através da técnica de imunohistoquímica, a pesquisa de mutações no gene CKIT será concretizada através da extração de DNA para PCR em blocos de parafina e a medição do volume médio nuclear utilizando métodos estereológicos. Em paralelo está também a ser explorada a aplicabilidade da espectroscopia de Raman nestes tumores. O culminar destas tarefas pretende contribuir para um melhor entendimento e previsão do comportamento destes tumores no cão.

description: The general aim of manifold estimation is reconstructing, by statistical methods, an $m$-dimensional compact manifold $S$ on ${\mathbb R}^d$ (with $m\leq d$) or estimating some relevant quantities related to the geometric properties of $S$. We will assume that the sample data are given by the distances to the $(d-1)$-dimensional manifold $S$ from points randomly chosen on a band surrounding $S$, with $d=2$ and $d=3$. The point in this paper is to show that, if $S$ belongs to a wide class of compact sets (which we call \it sets with polynomial volume\rm), the proposed statistical model leads to a relatively simple parametric formulation. In this setup, standard methodologies (method of moments, maximum likelihood) can be used to estimate some interesting geometric parameters, including curvatures and Euler characteristic. We will particularly focus on the estimation of the $(d-1)$-dimensional boundary measure (in Minkowski's sense) of $S$. It turns out, however, that the estimation problem is not straightforward since the standard estimators show a remarkably pathological behavior: while they are consistent and asymptotically normal, their expectations are infinite. The theoretical and practical consequences of this fact are discussed in some detail.

description: We study strings associated with minimal 6d SCFTs, which by definition have only one string charge and no Higgs branch. These theories are labelled by a number n with 1 <= n <= 8 or n = 12. Quiver theories have previously been proposed which describe strings of SCFTs for n = 1, 2. For n > 2 the strings interact with the bulk gauge symmetry. In this paper we find a quiver description for the n = 4 string using Sen's limit of F-theory and calculate its elliptic genus with localization techniques. This result is checked using the duality of F-theory with M-theory and topological string theory whose refined BPS partition function captures the elliptic genus of the SCFT strings. We use the topological string theory to gain insight into the elliptic genus for other values of n.

description: Antarctic minke whales (Balaenoptera bonaerensis, AMW) are an abundant, ice-dependent species susceptible to rapid climatic changes occurring in parts of the Antarctic. Here, we used remote biopsy samples and estimates of length derived from unoccupied aircraft system (UAS) to characterize for the first time the sex ratio, maturity, and pregnancy rates of AMWs around the Western Antarctic Peninsula (WAP). DNA profiling of 82 biopsy samples (2013–2020) identified 29 individual males and 40 individual females. Blubber progesterone levels indicated 59% of all sampled females were pregnant, irrespective of maturity. When corrected for sexual maturity, the median pregnancy rate was 92.3%, indicating that most mature females become pregnant each year. We measured 68 individuals by UAS (mean = 8.04 m) and estimated that 66.5% of females were mature. This study provides the first data on the demography of AMWs along the WAP and represents the first use of non-lethal approaches to studying this species. Furthermore, these results provide baselines against which future changes in population status can be assessed in this rapidly changing marine ecosystem.

description: Graphene-based Josephson junctions provide a novel platform for studying the proximity effect due to graphene's unique electronic spectrum and the possibility to tune junction properties by gate voltage. Here we describe graphene junctions with a mean free path of several micrometres, low contact resistance and large supercurrents. Such devices exhibit pronounced Fabry-Pérot oscillations not only in the normal-state resistance but also in the critical current. The proximity effect is mostly suppressed in magnetic fields below 10mT, showing the conventional Fraunhofer pattern. Unexpectedly, some proximity survives even in fields higher than 1 T. Superconducting states randomly appear and disappear as a function of field and carrier concentration, and each of them exhibits a supercurrent carrying capacity close to the universal quantum limit. We attribute the high-field Josephson effect to mesoscopic Andreev states that persist near graphene edges. Our work reveals new proximity regimes that can be controlled by quantum confinement and cyclotron motion.

description: We derive a criterion under which splitting of all eigenstates of an open $\XYZ$ Hamiltonian with boundary fields into two invariant subspaces, spanned by chiral shock states, occurs. The splitting is governed by an integer number, which has the geometrical meaning of the maximal number of kinks in the basis states. We describe the generic structure of the respective Bethe vectors. We obtain explicit expressions for Bethe vectors, in the absence of Bethe roots, and those generated by one Bethe root, and investigate the \multiplet. We also describe in detail an elliptic analogue of the spin-helix state, appearing in both the periodic and the open $\XYZ$ model, and derive the eigenstate condition. The elliptic analogue of the spin-helix state is characterized by a quasi-periodic modulation of the magnetization profile, governed by Jacobi elliptic functions.

description: The physics of shock-boundary layer interactions (SBLIs) in a supersonic turbine cascade at Mach 2.0 and Reynolds number 395,000, based on the axial chord, is investigated through a wall-resolved large eddy simulation. Special attention is given to the characterization of the low-frequency dynamics of the separation bubbles using flow visualization, spectral analysis, space-time cross correlations, and flow modal decomposition. The mean flowfield shows different shock structures formed on both sides of the airfoil. On the suction side, an oblique shock impinges on the turbulent boundary layer, whereas a Mach reflection interacts with the pressure side boundary layer. The interactions taking place in the present turbine cascade show similarities and discrepancies with respect to more canonical cases. For example, the characteristic frequencies of the shock/bubble motions are comparable to those described in the literature of canonical cases. However, the suction side bubble leads to compression waves that do not coalesce into a separation shock, and a thin bubble forms on the pressure side despite the strong normal shock from the Mach reflection. Instantaneous flow visualizations illustrate elongated streamwise structures on the incoming boundary layers and their interactions with the shocks and separation bubbles. The space-time cross-correlations reveal that the near-wall streaks drive the motion of the suction side separation bubble, which in turn promotes oscillations of the reattachment shock and shear layer flapping. Organized motions in the SBLIs and their corresponding characteristic frequencies and spatial support are identified using proper orthogonal decomposition.

description: Objetivos: Em março de 2020, a OMS a declarou estado de pandemia devido ao SARS-CoV-2. Em vários países, foram impostos confinamentos/ quarentenas com o objetivo de mitigar a transmissão do vírus, interrompendo as rotinas diárias das populações, expondo as pessoas e os animais a fatores de stress adicionais, tais como, stress psicossocial. Estudos recentes sugerem que o stress está totalmente envolvido na patofisiologia dos STUI. Este estudo retrospetivo teve como objetivo avaliar os efeitos da pandemia e dos confinamentos nos sinais do trato urinário inferior em gatos. Materiais e Métodos: Este estudo resulta de uma pesquisa por palavra-chave: Urianálise, na base de dados do Hospital Veterinário da AZP. Participaram no estudo 298 gatos, atendidos entre 2019 e 2021. Foi utilizado um grupo de controlo: grupo período pré-pandemia (PPP) com 142 gatos, atendidos entre 1/fevereiro/19 e 31/janeiro/20, e um grupo de estudo: grupo período durante a pandemia (PDP) com 156 gatos atendidos entre 1/fevereiro/20 e 31/janeiro/21. Resultados: Observou-se uma diminuição das obstruções/recidivas subsequente (p < 0,001) e uma diminuição da taxa de mortalidade (p < 0,05) no grupo PDP, comparativamente ao grupo de controlo. E foi observado ainda, uma diferença estatisticamente significativa relativamente ao número de episódios, com o grupo PPP associado a dois episódios, enquanto o grupo PDP se mostrou mais frequentemente com um episódio apenas (p < 0.01). Conclusão: Os resultados parecem demostrar um efeito positivo no comportamento e bem-estar dos gatos devido ao aumento de tempo despendido com os seus tutores, durante o período de confinamento.
