description: In this research we suggest to take advantage of the opportunities offered by the new information and communication technologies (NICT). This new techno-scientific process of investigation will be realized via a laboratory of CAE (Computer assisted experimentations) where the computer is the learning tool that seeks in real time concrete observations. Experimental know- how, and the using of abstract representations to solve problems. To do this, we have introduced innovated courses in Didactics based on ICT/CAE in our Masters programs in the Holy Spirit University of Kaslik (USEK). These courses are intended for initial and continuous training of our student-teachers in mathematics and science and technology. Subsequently, our student-teachers will use CAE with their students in high schools for teaching chemistry to test and validate the functional aspect of the environment CAE proposed. The educational validation of this paradigm will be based on the confrontation between a priori analysis and subsequent findings to measure the gap of understanding that students have acquired.

description: Tunisia, Arab Muslim country, is characterized by a concordist socio-cultural context. Students mobilize conceptions of the diversity of life that are a mixture of religious and scientific knowledge. The teaching of the biological evolution described in this paper addresses these concepts in classroom debates that include epistemological reflections on the scientific characteristics of evolution as a historical science. During the teaching, students have developed different explanations, manifested a better understanding of what is scientific knowledge and finally, many of them developed separate explanations of the diversity of life.

description: Narrow band imaging in the G-band is commonly used to trace the small magnetic field concentrations of the Sun, although the mechanism that makes them bright has remained unclear. We carry out LTE syntheses of the G-band in an assorted set of semi-empirical model magnetic concentrations. The syntheses include all CH lines as well as the main atomic lines within the band-pass. The model atmospheres produce bright G-band spectra having many properties in common with the observed G-band bright points. In particular, the contrast referred to the quiet Sun is about twice the contrast in continuum wavelengths. The agreement with observations does not depend on the specificities of the model atmosphere, rather it holds from single fluxtubes to MIcro-Structured Magnetic Atmospheres. However, the agreement requires that the real G-band bright points are not spatially resolved, even in the best observations. Since the predicted G-band intensities exceed by far the observed values, we foresee a notable increase of contrast of the G-band images upon improvement of the angular resolution. According to the LTE modeling, the G-band spectrum emerges from the deep photosphere that produces the continuum. Our syntheses also predict solar magnetic concentrations showing up in continuum images but not in the G-band . Finally, we have examined the importance of the CH photo-dissociation in setting the amount of G-band absorption. It turns out to play a minor role.

description: In this paper we present some aspects of a longitudinal and exploratory study developed in the secondary school in Argentina. We use the ideas of Pedagogy of research and questioning the world and Course of study and research (CSR) of the Anthropological Theory of Didactics (TAD). We have carried out this pedagogy in a local and controlled way in the 4th and 5th year of the high school. We developed a (CSR) around the question: How to do operations with whatever graph if we only know their graphic representations and the unit on the axes? The work proposes the mathematical organization of reference, the mathematical organizations we’ve really met developing the CSR, and those we could meet. We analyze the mathematical activity in the classroom and the difficulties that we faced adopting the pedagogy of research and questioning the world in secondary school classrooms in Argentine.

description: With the rapid developments in quantum hardware comes a push towards the first practical applications on these devices. While fully fault-tolerant quantum computers may still be years away, one may ask if there exist intermediate forms of error correction or mitigation that might enable practical applications before then. In this work, we consider the idea of post-processing error decoders using existing quantum codes, which are capable of mitigating errors on encoded logical qubits using classical post-processing with no complicated syndrome measurements or additional qubits beyond those used for the logical qubits. This greatly simplifies the experimental exploration of quantum codes on near-term devices, removing the need for locality of syndromes or fast feed-forward, allowing one to study performance aspects of codes on real devices. We provide a general construction equipped with a simple stochastic sampling scheme that does not depend explicitly on a number of terms that we extend to approximate projectors within a subspace. This theory then allows one to generalize to the correction of some logical errors in the code space, correction of some physical unencoded Hamiltonians without engineered symmetries, and corrections derived from approximate symmetries. In this work, we develop the theory of the method and demonstrate it on a simple example with the perfect $[[5,1,3]]$ code, which exhibits a pseudo-threshold of $p \approx 0.50$ under a single qubit depolarizing channel applied to all qubits. We also provide a demonstration under the application of a logical operation and performance on an unencoded hydrogen molecule, which exhibits a significant improvement over the entire range of possible errors incurred under a depolarizing channel.

description: This thesis explores the international Book Town Movement that, from its beginnings in the small Welsh market town of Hay-on-Wye in the early 1960s, has escalated to incorporate more than 50 villages and towns in 27 countries. This phenomenon has enabled peripheral communities in Europe and across the globe to reclaim their economic futures and impact on the cultural sphere as increasingly powerful sites and sources of creativity. This study seeks to understand the reasons for this renaissance of interest in the preservation of traditional print culture in the countryside at a point in history when the book publishing industry is in a state of flux as it adapts to new digital technologies and globalisation of markets, leading to a clarification of the relationship between new books and the second-hand book economy. At the centre of this investigation is an acknowledgement of the book as a unique item of cultural consumption and a catalyst in book town creation – at once a remarkable artefact and a springboard for contemporary cultural debate. Essential to an understanding of book towns is their location on the geographical periphery and their capacity to sustain regional culture and identity. This thesis analyses innovative book town examples from diverse parts of the world using four key research methods: site-based research, case study research, cultural policy research and book culture research. This research aims to inform a broader discussion of regional regeneration and cultural policy development through an investigation of book towns as ‘down on their luck’ places, reanimated to celebrate remarkable pasts and designed to captivate a growing middle-class cohort drawn to nostalgia, history, cultural heritage and tranquil rural settings that deliver both intellectual stimulation and wellbeing. The synergy of the book town ethos with a number of evolving global tourism trends – including cultural tourism and, more recently, post-tourism – has heightened their desirability. By exploring the history and origins of the Book Town Movement, the thesis links book towns to the entrepreneurship of bibliophiles seeking more utopian lifestyles, and culture-led regeneration by governments wanting to harness their capacity to increase social capital and generate economic revival.

description: The empirical material of this preliminary study was drawn from the recording and analysis of teaching activities used during the implementation of the new pre-school Greek curriculum in sixteen classes of public kindergartens. More specifically, according to the opinion of the kindergarten teachers about the social backgrounds of the majority of their students, 8 kindergartens belonged in a middle-class social context and 8 in a working-class social context. Research findings showed variations in the pedagogical practices in those two types of kindergartens. Variations were observed in the choices made by pre-school teachers in the development of mathematical knowledge in the classroom, in the ways that teachers and students interact during the teaching process, in the organization of the classroom, and in the application of evaluative rules and teaching strategies for teaching mathematics.

Subjects: subject: heme iron
subject: colorectal cancer
subject: tumorigenesis
subject: HFE gene polymorphism

description: Iron in the form of either heme or non-heme is of paramount importance for the physiological functioning of cells supporting respiratory and oxidative mechanisms, cell viability and proliferation. However, a pathological level of cellular iron is suggested to initiate carcinogenesis and other non-neoplastic diseases, possibly owing to its ability to generate reactive oxygen species. Heme iron, which is abundant in the typical western diet due to its presence in red/processed meat, has been hypothesised to be one of the main causative factors for the high incidence of colorectal cancer (CRC) in the westernized world. Moreover, the heme oxygenase (HO) complex, HO-1 in particular, is thought to be linked to colorectal carcinogenesis via ambiguous mechanisms, which require further research aiming deeper understanding. Furthermore, mutations in one of the main iron homeostatic genes, HFE (homeostatic iron regulator), are postulated to cause intracellular iron accumulation paving the way to tumorigenesis. However, there are vast gaps in knowledge in relation to these hypotheses, warranting further extensive research. Given this background, the present research aimed to explore heme mediated cellular and genetic alterations in colorectal carcinogenesis, the clinicopathological significance of HO-1 and HO-2 expression profiles in CRC and the relevance of HFE expression status and mutations in CRC pathogenesis.

description: Modelling of high resolution Balmer line profiles in the early-time spectra of SN 1998S shows that the inferred fast (roughly 400 km/s) circumstellar (CS) gas on days 23 and 42 post-explosion is confined to a narrow, negative velocity gradient shell just above the photosphere. This gas may be identified with a slow (v < 40 km/s) progenitor wind accelerated at the ejecta-wind interface. In this scenario, the photosphere coincides with a cool dense shell formed in the reverse shock. Acceleration by radiation from the supernova or by a shock-accelerated relativistic particle precursor are both possible explanations for the observed fast CS gas. An alternative, equally plausible scenario is that the fast CS gas is accelerated within shocked clouds engulfed by the outer shock, as it propagates through the intercloud wind.

description: We propose a class of models for a magnonic analog of topological insulators in three dimensions. The models have pseudo-time-reversal symmetry which ensures the existence of bosonic Kramers pairs. We define a set of $\mathbb{Z}_2$ topological invariants that characterizes different topological phases and determines the presence or absence of surface Dirac cones. This is demonstrated by considering a bosonic counterpart of the Fu-Kane-Mele model on a diamond lattice. The model is found to exhibit three distinct phases analogous to strong topological, weak topological, and trivial insulator phases of the original fermionic model. We also discuss a possible realization of the thermal Hall effect of surface magnons in the presence of a magnetic field in proximity to a normal ferromagnet.

This study is motivated by a desire to investigate the possibility of using recently developed powerful ultrashort (femtosecond) laser pulses to demonstrate the existence of nonlinear effects in vacuum, predicted by quantum electrodynamics (QED). An approach, similar to classical nonlinear optics in a medium, is developed in this article. A third order nonlinear effective susceptibility of vacuum is then introduced .

These data provide a large increase in the number of low surface brightness galaxies for which accurate rotation curves are available. They also represent an order of magnitude improvement in spatial resolution over previous 21 cm studies (1" to 2" instead of 13" to 45"). The improved resolution and accuracy of the data extend and strengthen the scientific conclusions previously inferred from 21 cm data.

description: We present a rederivation of the baryon and lepton numbers $\frac{1}{2}$ of the $SU(2)_L$ S sphaleron of the standard electroweak theory based on spectral mirror symmetry. We explore the properties of a fermionic Hamiltonian under discrete transformations along a noncontractible loop of field configurations that passes through the sphaleron and whose endpoints are the vacuum. As is well known, CP transformation is not a symmetry of the system anywhere on the loop, except at the endpoints. By augmenting CP with a chirality transformation, we observe that the Dirac Hamiltonian is odd under the new transformation precisely at the sphaleron, and this ensures the mirror symmetry of the spectrum, including the continua. As a consistency check, we show that the fermionic zero mode presented by Ringwald in the sphaleron background is invariant under the new transformation. The spectral mirror symmetry which we establish here, together with the presence of the zero mode, are the two necessary conditions whence the fermion number $\frac{1}{2}$ of the sphaleron can be inferred using the reasoning presented by Jackiw and Rebbi or, equivalently, using the spectral deficiency $\frac{1}{2}$ of the Dirac sea. The relevance of this analysis to other solutions is also discussed.

ISO-LWS two colour diagram of young stellar objects

description: We present a [60--100] vs. [100--170] $μ$m two colour diagram for a sample of 61 young stellar objects (YSOs) observed with the Long Wavelength Spectrometer (LWS) on-board the Infrared Space Observatory (ISO). The sample consists of 17 Class 0 sources, 15 Class I, 9 Bright Class I ($L_{\rm bol}>10^4 L_\odot$), 20 Class II (14 Herbig Ae/Be stars and 6 T Tauri stars). We find that each class occupies a well defined region in our diagram with colour temperatures increasing from Class 0 to Class II. Therefore the [60--100] vs. [100--170] two colours diagram is a powerful and simple tool to derive from future (e.g. with the Herschel Space Observatory) photometric surveys the evolutionary status of YSOs. The advantage over other tools already developed is that photometry at other wavelengths is not required: three flux measurements are enough to derive the evolutionary status of a source. As an example we use the colours of the YSO IRAS 18148$-$0440 to classify it as Class I. The main limitation of this work is the low spatial resolution of the LWS which, for some objects, causes a high uncertainty in the measured fluxes due to the background emission or to the source confusion inside the LWS beam.

Deep learning frameworks for clinical diagnosis - a healthcare system

description: One of the main targets of computer vision is to interpret the content of image and video. To interpret image content, one of the essential goals is to build a model depending on a known set of features extracted from image data. The built model is then employed to produce inference of the unknown data-set. Medical image segmentation is the part of computer vision and its target is to labeling each pixel of an object of interest. It is often a key task for clinical applications, varying from computer aided diagnosis for lesions detection to therapy planning and guidance. Medical image segmentation helps clinicians focus on a particular area of the disease and extract detailed information for a more accurate diagnosis. An end to end deep learning approach, Convolutional Neural Networks have shown state-of-the-art performance for automated medical image segmentation. However, it doesn’t perform well in case of complex environments. U-Net is another popular deep learning architecture especially for biomedical imaging. It consists of contraction and expansion path to pixel-wise predict the dataset. This model is better than previously available medical image segmentation approaches. However again, it fails to produce the promising results with voxels. For that, incremental version of U-Net, Multiplanar U-Net has been developed in 2019. In this talk, we will discuss about a simple and thoroughly evaluated deep learning frameworks for segmentation of arbitrary medical image volumes. We will also discuss about specific framework, which doesn’t require human interaction, task-specific information and it is based on a fixed model topology and hyper parameter set.

description: We study the three-dimensional static configurations of nonhomogeneous Kirchhoff filaments with periodically varying Young's modulus. This type of variation may occur in long tandemly repeated sequences of DNA. We analyse the effects of the Young's modulus frequence and amplitude of oscillation in the stroboscopic maps, and in the regular (non chaotic) spatial configurations of the filaments. Our analysis shows that the tridimensional conformations of long filaments may depend critically on the Young's modulus frequence in case of resonance with other natural frequencies of the filament. As expected, far from resonance the shape of the solutions remain very close to that of the homogeneous case. In the case of biomolecules, it is well known that various other elements, besides sequence-dependent effects, combine to determine their conformation, like self-contact, salt concentration, thermal fluctuations, anisotropy and interaction with proteins. Our results show that sequence-dependent effects alone may have a significant influence on the shape of these molecules, including DNA. This could, therefore, be a possible mechanical function of the ``junk'' sequences.

description: This paper studies the reconstruction of Stekloff eigenvalues and the index of refraction of an inhomogeneous medium from Cauchy data. The inverse spectrum problem to reconstruct Stekloff eigenvalues is investigated using a new integral equation for the reciprocity gap method. Given reconstructed eigenvalues, a Bayesian approach is proposed to estimate the index of refraction. Moreover, since it is impossible to know the multiplicities of the reconstructed eigenvalues and since the eigenvalues can be complex, we employ the recently developed spectral indicator method to compute Stekloff eigenvalues. Numerical experiments validate the effectiveness of the proposed methods.

Relativistic large scale jets and minimum power requirements

description: The recent discovery, by the Chandra satellite, that jets of blazars are strong X-ray emitters at large scales (0.1-1 Mpc) bears support to the hypothesis that (also) on these scales the emitting plasma is moving at highly relativistic speeds. In this case in fact the emission via inverse Compton scattering off cosmic background photons is enhanced and the resulting predicted X-ray spectrum well accounts for the otherwise puzzling observations. Here we point out another reason to favor relativistic large scale jets, based on a minimum power argument: by estimating the Poynting flux and bulk kinetic powers corresponding to, at least, the relativistic particles and magnetic field responsible for the emission, one can derive the value of the bulk Lorentz factor for which the total power is minimized. It is found that both the inner and extended parts of the jet of PKS 0637-752 satisfy such condition.

description: In this article we study the asymptotic behavior of incompressible, ideal, time-dependent two dimensional flow in the exterior of a single smooth obstacle when the size of the obstacle becomes very small. Our main purpose is to identify the equation satisfied by the limit flow. We will see that the asymptotic behavior depends on $γ$, the circulation around the obstacle. For smooth flow around a single obstacle, $γ$ is a conserved quantity which is determined by the initial data. We will show that if $γ= 0$, the limit flow satisfies the standard incompressible Euler equations in the full plane but, if $γ\neq 0$, the limit equation acquires an additional forcing term. We treat this problem by first constructing a sequence of approximate solutions to the incompressible 2D Euler equation in the full plane from the exact solutions obtained when solving the equation on the exterior of each obstacle and then passing to the limit on the weak formulation of the equation. We use an explicit treatment of the Green's function of the exterior domain based on conformal maps, {\it a priori} estimates obtained by carefully examining the limiting process and the Div-Curl Lemma, together with a standard weak convergence treatment of the nonlinearity for the passage to the limit.

description: The two-photon-induced singlet fission was observed in rubrene single crystal and studied by use of femtosecond pump-probe spectroscopy. The location of two-photon excited states was obtained from the nondegenerate two-photon absorption (TPA) spectrum. Time evolution of the two-photon-induced transient absorption spectra reveals the direct singlet fission from the two-photon excited states. The TPA absorption coefficient of rubrene single crystal is 52 cm/GW at 740 nm, as obtained from Z-scan measurements. Quantum chemical calculations based on time-dependent density functional theory support our experimental data.

description: We introduce the Stars and MUltiphase Gas in GaLaxiEs -- SMUGGLE model, an explicit and comprehensive stellar feedback model for the moving-mesh code arepo. This novel sub-resolution model resolves the multiphase gas structure of the interstellar medium and self-consistently generates gaseous outflows. The model implements crucial aspects of stellar feedback including photoionization, radiation pressure, energy and momentum injection from stellar winds and from supernovae. We explore this model in high-resolution isolated simulations of Milky Way-like disc galaxies. Stellar feedback regulates star formation to the observed level and naturally captures the establishment of a Kennicutt-Schmidt relation. This result is achieved independent of the numerical mass and spatial resolution of the simulations. Gaseous outflows are generated with average mass loading factors of the order of unity. Strong outflow activity is correlated with peaks in the star formation history of the galaxy with evidence that most of the ejected gas eventually rains down onto the disc in a galactic fountain flow that sustains late-time star formation. Finally, the interstellar gas in the galaxy shows a distinct multiphase distribution with a coexistence of cold, warm and hot phases.

description: Long ago, Newman and Janis showed that a complex deformation $z\rightarrow z+i a$ of the Schwarzschild solution produces the Kerr solution. The underlying explanation for this relationship has remained obscure. The complex deformation has an electromagnetic counterpart: by shifting the Coloumb potential, we obtain the EM field of a certain rotating charge distribution which we term $\sqrt{\rm Kerr}$. In this note, we identify the origin of this shift as arising from the exponentiation of spin operators for the recently defined "minimally coupled" three-particle amplitudes of spinning particles coupled to gravity, in the large-spin limit. We demonstrate this by studying the impulse imparted to a test particle in the background of the heavy spinning particle. We first consider the electromagnetic case, where the impulse due to $\sqrt{\rm Kerr}$ is reproduced by a charged spinning particle; the shift of the Coloumb potential is matched to the exponentiated spin-factor appearing in the amplitude. The known impulse due to the Kerr black hole is then trivially derived from the gravitationally coupled spinning particle via the double copy.

description: We compare the parallaxes of stars from VLBI astrometry in the literature to those in the Gaia DR2 catalog. Our full sample contains young stellar objects, evolved AGB stars, pulsars and other radio stars. Excluding AGB stars, which show significant discrepancies between Gaia and VLBI parallaxes, and stars in binary systems, we obtain an average, systematic, parallax offset of $-75 \pm 29~μ$as for Gaia DR2, consistent with their estimate of a parallax zero-point between $-100$ and 0 $μ$as.
