description: We construct the time-evolution for the second quantized Dirac equation subject to a smooth, compactly supported, time dependent electromagnetic potential and identify the degrees of freedom involved. Earlier works on this (e.g. Ruijsenaars) observed the Shale-Stinespring condition and showed that the one-particle time-evolution can be lifted to Fock space if and only if the external field had zero magnetic components. We scrutinize the idea, observed earlier by Fierz and Scharf, that the time-evolution can be implemented between time varying Fock spaces. In order to define these Fock spaces we are led to consider classes of reference vacua and polarizations. We show that this implementation is up to a phase independent of the chosen reference vacuum or polarization and that all induced transition probabilities are well-defined and unique.

description: Astronomy in Secondary Schools: Curriculum to Establishment Presenter: Prasad Rathod, Syzygy Outreach Space Club, India Collaborators: Vriddhi Gupta, Priyanka Lakariya, Abrar Sayyed, and Jonack Abdullah Al Mahamud. This was a poster presented at the 4th Shaw-IAU Workshop on Astronomy for Education, organised by the IAU Office of Astronomy for Education (OAE, http//astro4edu.org). Cognitive evolution of the brain maps our curriculum. Establishment of labs & utilisation of existing facilities is stressed. Survey of schools with/without astronomy courses forms our database. A learning model is proposed which utilises pre-existing subjects to promote astronomy. A demographic study was conducted to gather information about institutions having astronomical setups to be used as Nodal centres. To remove the fear of future uncertainty, inclusion of space startups will be done to provide internships. Research focuses on creating ecosystems within Nodal centres of under-graduates, post-graduates & PhD students pursuing astronomy to improve the syllabus and help students with their projects. MoUs schemes are devised to fulfil gaps with universities globally. About the 4th Shaw-IAU Workshop: The topic for this year’s Shaw-IAU Workshop on Astronomy for Education is ‘Leveraging the potential of astronomy in formal education’ and is scheduled to run 15 to 17 November 2022 as a fully virtual event on Hopin as in previous years. This year’s Shaw-IAU Workshop focuses on the role of astronomy in the core regions of formal, primary and secondary, education: How do we teach astronomy as its own subject? What is the role of astronomy in teaching physics or chemistry – or in communicating such a central future topic as climate change? In sessions marked with a * we aim to hear specifically from teachers. We also address the question of how to approach those who set the framework for teaching: How can you get your administration, or at a much higher level: your education ministry, to listen to you? Last but not least we look at how to bridge the divide between the fundamentals that are commonly taught in school and results from cutting-edge research, which tend to be fascinating to students and the general public alike. he workshop was organised by the IAU Office of Astronomy for Education (http://astro4edu.org).

This was a poster presented at the 4th Shaw-IAU Workshop on Astronomy for Education, organised by the IAU Office of Astronomy for Education (OAE, http//astro4edu.org). The Subaru Telescope is a large optical-infrared telescope near the summit of Maunakea, Hawaii. The telescope conducted an extensive survey called the Hyper Suprime-Cam (HSC) Subaru Strategic Program using the ultrawide-field imaging camera HSC. The big survey data is partially open to the public, and anyone can freely explore the vast cosmic images on the hscMap website. The three high-school science teachers (Hara, Togashi, and Hiratsuka) in Japan developed educational material using hscMap to bring one of the world’s highest-quality astronomical data to their classrooms, including at a University. According to a questionnaire after Hara’s lecture at a teacher-training course at Toyo University, many trainee students were interested in using hscMap when they became teachers.

Gravitational Lensing Corrections in Flat LambdaCDM Cosmology

description: We compute the deflection angle to order (m/r_0)^2 and m/r_0*Lambda r_0^2 for a light ray traveling in a flat LambdaCDM cosmology which encounters a completely condensed mass region. We use a Swiss cheese model for the inhomogeneities and find that the most significant correction to the Einstein angle occurs not because of the non-linear terms but instead occurs because the condensed mass is embedded in a background cosmology.The Swiss cheese model predicts a decrease in the deflection angle of ~2% for weakly lensed galaxies behind the rich cluster A1689, and that the reduction can be as large as ~5% for similar rich clusters at z\approx 1. Weak lensing deflection angles caused by galaxies can likewise be reduced by as much as ~4%. We show that the lowest order correction in which Lambda appears is proportional to m/r_0*\sqrt{Lambda r_0^2} and could cause as much as a ~0.02% increase in the deflection angle for light that passes through a rich cluster. The lowest order non-linear correction in the mass is proportional to m/r_0*\sqrt{m/r_0} and can increase the deflection angle by ~0.005% for weak lensing by galaxies.

Fosfina e Venere: non è ancora detta l’ultima parola
Creators: Claudia Mignone
Publisher: name: Media Inaf
Year: 2020

Prosegue, a colpi di paper, il dibattito sulla presenza o meno della fosfina – rara molecola che sulla Terra viene prodotta da fenomeni industriali ma anche da alcuni batteri – nelle nubi della nostra vicina planetaria, Venere. Diversi team scientifici hanno contestato alcune delle procedure usate, mettendo in dubbio la solidità del risultato e riscontrando peraltro delle inconsistenze nella calibrazione delle osservazioni Alma. Nel frattempo, dati corretti alla mano, il team che aveva annunciato la scoperta ha ridimensionato le proprie conclusioni, pur senza fare dietro-front completo. Un’avvincente saga scientifica che, forse, si risolverà solo il prossimo anno con nuove osservazioni

description: A Pedagogical Activity to Teach the Seasons Presenter: Oscar Rodrigues dos Santos, Federal Technological University of Paraná, Brazil Collaborators: Michel Corci Batista (Federal Technological University of Paraná), Veridiane Cristina Matins (State Department of Education) and Taisy Fernandes Vieira (State Department of Education). In elementary school, astronomy represents the gateway to the study of physics, especially in the final years. Through a simple experimental activity with the students’ participation, the seasons of the year can be studied in different latitudes. It is easy to explain phenomena such as the midnight Sun, the apparent motion of the Sun, and the influence of the tilt of the Earth’s axis using an experimental apparatus. Also, why the equatorial region has a more temperate climate, whereas the temperatures near the poles tend to be more severe.

description: We propose a scalable and data-driven approach to learn shape distributions from large databases of healthy organs. To do so, volumetric segmentation masks are embedded into a common probabilistic shape space that is learned with a variational auto-encoding network. The resulting latent shape representations are leveraged to derive zeroshot and few-shot methods for abnormal shape detection. The proposed distribution learning approach is illustrated on a large database of 1200 healthy pancreas shapes. Downstream qualitative and quantitative experiments are conducted on a separate test set of 224 pancreas from patients with mixed conditions. The abnormal pancreas detection AUC reached up to 65.41% in the zero-shot configuration, and 78.97% in the few-shot configuration with as few as 15 abnormal examples, outperforming a baseline approach based on the sole volume.

Representations of Astronomy in Children's Storybooks

Subjects: Astronomy Education

description: Representations of Astronomy in Children’s Storybooks Presenter: Alison Allen, Rockman et al. Cooperative, USA Collaborator: Julia D. Plummer, The Pennsylvania State University, USA This was a poster presented at the 4th Shaw-IAU Workshop on Astronomy for Education, organised by the IAU Office of Astronomy for Education (OAE, http//astro4edu.org). Storybooks are widely used in schools as an entry point into science learning. As a result, storybooks should provide an accurate and equitable representation of science and scientists. Therefore, we conducted a content analysis of 32 astronomy storybooks published between 2001-2021. While about half the books include characters using at least one science practice, few portrayed characters investigating an astronomical phenomenon. Half the books contained inaccuracies. Gender representation was relatively balanced. The sample includes a relatively even distribution of characters’ racial background; yet, this balance disappeared when books from Diverse Book Finder were removed from the sample. Our study suggests that there are limitations in how current children’s books represent astronomy. About the 4th Shaw-IAU Workshop: The topic for this year’s Shaw-IAU Workshop on Astronomy for Education is ‘Leveraging the potential of astronomy in formal education’ and is scheduled to run 15 to 17 November 2022 as a fully virtual event on Hopin as in previous years. This year’s Shaw-IAU Workshop focuses on the role of astronomy in the core regions of formal, primary and secondary, education: How do we teach astronomy as its own subject? What is the role of astronomy in teaching physics or chemistry – or in communicating such a central future topic as climate change? In sessions marked with a * we aim to hear specifically from teachers. We also address the question of how to approach those who set the framework for teaching: How can you get your administration, or at a much higher level: your education ministry, to listen to you? Last but not least we look at how to bridge the divide between the fundamentals that are commonly taught in school and results from cutting-edge research, which tend to be fascinating to students and the general public alike. he workshop was organised by the IAU Office of Astronomy for Education (http://astro4edu.org).

description: We study two metrics, the quasihyperbolic metric and the distance ratio metric of a subdomain $G \subset {\mathbb R}^n$. In the sequel, we investigate a class of domains, so called $φ$-uniform domains, defined by the property that these two metrics are comparable with respect to a homeomorphism $φ$ from $[0,\infty)$ to itself. Finally, we discuss a number of stability properties of $φ$-uniform domains. In particular, we show that the class of $φ$-uniform domains is stable in the sense that removal of a geometric sequence of points from a $φ$-uniform domain yields a $φ_1$-uniform domain.

description: Le réchauffement climatique est un thème récurrent dans les médias. Les scientifiques du monde entier tirent la sonnette d’alarme concernant l’urgence d’agir et de plus en plus de manifestations émergent afin de faire pression sur nos politiques pour la mise en place d’un changement. Rythmés par ces événements, les élèves du secondaire 1 s’interrogent et tentent d’obtenir des réponses de la part des enseignants. Quelles connaissances leur apporter pour leur permettre d’acquérir une réflexion citoyenne éclairée ? Interpellés par nos élèves en cours de sciences, nous avons souhaité savoir si les moyens d’enseignement romands (MER) de sciences apportent des informations suffisantes aux élèves sur le sujet du réchauffement climatique. Après avoir vérifié l’adéquation des objectifs d’apprentissage visés par les plans d’étude romands (PER) de sciences et de géographie avec notre sujet d’étude, nous avons analysé en détail le rapport du GIEC de 2014 pour identifier les savoirs clefs. Utilisant les résultats de travaux de recherche similaires au notre, nous avons aussi identifié plusieurs obstacles épistémologiques possibles et les éléments à enseigner nécessaires pour lever ces obstacles. Nous avons alors conduit une analyse approfondie des MER de sciences et de géographie et nous avons rassemblé nos résultats dans 3 cartes conceptuelles, laissant apparaître toute la complexité de ce sujet. Nous avons notamment observé que : 1) les éléments des MER se raccordent à la plupart des concepts du réchauffement climatique, mais 2) les savoirs restent assez superficiels, alors que plusieurs séquences seraient propices à un apprentissage plus détaillé, 3) les éléments abordés font plutôt référence à des faits passés qu’à des recherches de solutions pour l’avenir, 4) les savoirs enseignés sont plutôt des éléments théoriques que des propositions d’action pour les élèves, 5) plusieurs points ou obstacles ne sont pas abordés, et 6) les MER de sciences ne proposent que très peu de savoirs, la quasi totalité de l’enseignement de cette thématique étant dédiée à la géographie. Nous pensons qu’un rééquilibrage entre géographie et sciences serait souhaitable afin de mieux présenter les diverses facettes de cette question socialement vive aux élèves. De plus, une formation conjointe des enseignants de géographie et de sciences semble nécessaire pour élargir leurs compétences et poser les fondements de projets interdisciplinaires sur cette thématique du réchauffement climatique.
Astronomy Education in Primary Schools: Characteristic, Discrepancy, and Implementation

Astronomy is a very important but quite different subject for school education, because of the characteristic of astronomy with the vast scale of universe. The frequently-appeared new discoveries and astronomical phenomena with grand observability make astronomy the most suitable tool to keep and improve the curiosity (and even integrity) of students. A text book on astronomy course in schools would be different with other subjects like language, art, math, and physics. Some special considerations for astronomy education in primary school should be noted. About the 4th Shaw-IAU Workshop: The topic for this year’s Shaw-IAU Workshop on Astronomy for Education is ‘Leveraging the potential of astronomy in formal education’ and is scheduled to run 15 to 17 November 2022 as a fully virtual event on Hopin as in previous years. This year’s Shaw-IAU Workshop focuses on the role of astronomy in the core regions of formal, primary and secondary, education: How do we teach astronomy as its own subject?

What is a quantum computer, and how do we build one?
Creators: name: Perez-Delgado, Carlos A.
name: Kok, Pieter
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The DiVincenzo criteria for implementing a quantum computer have been seminal in focussing both experimental and theoretical research in quantum information processing. These criteria were formulated specifically for the circuit model of quantum computing. However, several new models for quantum computing (paradigms) have been proposed that do not seem to fit the criteria well. The question is therefore what are the general criteria for implementing quantum computers. To this end, a formal operational definition of a quantum computer is introduced. It is then shown that according to this definition a device is a quantum computer if it obeys the following four criteria: Any quantum computer must (1) have a quantum memory; (2) facilitate a controlled quantum evolution of the quantum memory; (3) include a method for cooling the quantum memory; and (4) provide a readout mechanism for subsets of the quantum memory. The criteria are met when the device is scalable and operates fault-tolerantly. We discuss various existing quantum computing paradigms, and how they fit within this framework. Finally, we lay out a roadmap for selecting an avenue towards building a quantum computer. This is summarized in a decision tree intended to help experimentalists determine the most natural paradigm given a particular physical implementation.
Signal Photon Flux and Background Noise in a Coupling Electromagnetic Detecting System for High Frequency Gravitational Waves

description: A coupling system between Gaussian type-microwave photon flux, static magnetic field and fractal membranes (or other equivalent microwave lenses) can be used to detect high-frequency gravitational waves (HFGWs) in the microwave band. We study the signal photon flux, background photon flux and the requisite minimal accumulation time of the signal in the coupling system. Unlike pure inverse Gertsenshtein effect (G-effect) caused by the HFGWs in the GHz band, the the electromagnetic (EM) detecting scheme (EDS) proposed by China and the US HFGW groups is based on the composite effect of the synchro-resonance effect and the inverse G-effect. Key parameters in the scheme include first-order perturbative photon flux (PPF) and not the second-order PPF; the distinguishable signal is the transverse first-order PPF and not the longitudinal PPF; the photon flux focused by the fractal membranes or other equivalent microwave lenses is not only the transverse first-order PPF but the total transverse photon flux, and these photon fluxes have different signal-to-noise ratios at the different receiving surfaces. Theoretical analysis and numerical estimation show that the requisite minimal accumulation time of the signal at the special receiving surfaces and in the background noise fluctuation would be $\sim10^3-10^5$ seconds for the typical laboratory condition and parameters of $h_{r.m.s.}\sim10^{-26}-10^{-30}$ at 5GHz with bandwidth $\sim$1Hz. In addition, we review the inverse G-effect in the EM detection of the HFGWs, and it is shown that the EM detecting scheme based only on the pure inverse G-effect in the laboratory condition would not be useful to detect HFGWs in the microwave band.

Typical signs of hypertension such as arteriosclerosis, nephrosclerosis, fatty degeneration of the liver and hemorrhages were common. Insulin therapy and omission of protein from the diet did not lessen the extent of the pathological conditions. It was concluded that the animals were responding to alloxan as an agent of stress in conformity with the adaptation syndrome and that the high salt content of the diet aggravated and sustained the resulting hypertension. The pathology of alloxan diabetes, which differs from that of diabetes mellitus, is changed to that of the latter by the salt diet. Because of the salt craving of diabetics, it is suggested that the hypertension often associated with diabetes is largely due to the salt intake.

Sei milioni di secondi – vale a dire l’intero tempo in palio per il “Multi-Year Heritage Program”, il programma scientifico più visionario del telescopio spaziale europeo per raggi X, che proprio oggi compie ventun’anni – vanno a due progetti proposti da due astrofisici dell’Inaf: Gabriele Ponti e Luca Zappacosta. Ecco come li impiegheranno

description: We study experimentally and theoretically transition phenomena caused by the external forcing from Rayleigh-Benard convection with the large-scale circulation (LSC) to the limiting regime of unstably stratified turbulent flow without LSC whereby the temperature field behaves like a passive scalar. In the experiments we use the Rayleigh-Bénard apparatus with an additional source of turbulence produced by two oscillating grids located nearby the side walls of the chamber. When the frequency of the grid oscillations is larger than 2 Hz, the large-scale circulation (LSC) in turbulent convection is destroyed, and the destruction of the LSC is accompanied by a strong change of the mean temperature distribution. However, in all regimes of the unstably stratified turbulent flow the ratio $\big[(\ell_x \nabla_x T)^2 + (\ell_y \nabla_y T)^2 + (\ell_z \nabla_z T)^2\big] / < θ^2 >$ varies slightly (even in the range of parameters whereby the behaviour of the temperature field is different from that of the passive scalar). Here $\ell_i$ are the integral scales of turbulence along x, y, z directions, T and θare the mean and fluctuating parts of the fluid temperature. At all frequencies of the grid oscillations we have detected the long-term nonlinear oscillations of the mean temperature. The theoretical predictions based on the budget equations for turbulent kinetic energy, turbulent temperature fluctuations and turbulent heat flux, are in agreement with the experimental results.
