description: We introduce a new sharp interface model for the flow of two immiscible, viscous, incompressible fluids. In contrast to classical models for two-phase flows we prescribe an evolution law for the interfaces that takes diffusional effects into account. This leads to a coupled system of Navier-Stokes and Mullins-Sekerka type parts that coincides with the asymptotic limit of a diffuse interface model. We prove the long-time existence of weak solutions, which is an open problem for the classical two-phase model. We show that the phase interfaces have in almost all points a generalized mean curvature.

description: We give an alternative proof of Madsen-Weiss' generalized Mumford conjecture. Our proof is based on ideas similar to Madsen-Weiss' original proof, but it is more geometrical and less homotopy theoretical in nature. At the heart of the argument is a geometric version of Harer stability, which we formulate as a theorem about folded maps.

description: We address the difficult question of inferring plausible node mobility based only on information from wireless contact traces. Working with mobility information allows richer protocol simulations, particularly in dense networks, but requires complex set-ups to measure, whereas contact information is easier to measure but only allows for simplistic simulation models. In a contact trace a lot of node movement information is irretrievably lost so the original positions and velocities are in general out of reach. We propose a fast heuristic algorithm, inspired by dynamic force-based graph drawing, capable of inferring a plausible movement from any contact trace, and evaluate it on both synthetic and real-life contact traces. Our results reveal that (i) the quality of the inferred mobility is directly linked to the precision of the measured contact trace, and (ii) the simple addition of appropriate anticipation forces between nodes leads to an accurate inferred mobility.

description: Over the last years, many face analysis tasks have accomplished astounding performance, with applications including face generation and 3D face reconstruction from a single "in-the-wild" image. Nevertheless, to the best of our knowledge, there is no method which can produce render-ready high-resolution 3D faces from "in-the-wild" images and this can be attributed to the: (a) scarcity of available data for training, and (b) lack of robust methodologies that can successfully be applied on very high-resolution data. In this work, we introduce the first method that is able to reconstruct photorealistic render-ready 3D facial geometry and BRDF from a single "in-the-wild" image. We capture a large dataset of facial shape and reflectance, which we have made public. We define a fast facial photorealistic differentiable rendering methodology with accurate facial skin diffuse and specular reflection, self-occlusion and subsurface scattering approximation. With this, we train a network that disentangles the facial diffuse and specular BRDF components from a shape and texture with baked illumination, reconstructed with a state-of-the-art 3DMM fitting method. Our method outperforms the existing arts by a significant margin and reconstructs high-resolution 3D faces from a single low-resolution image, that can be rendered in various applications, and bridge the uncanny valley.

Cosa è Evidente e cosa è Fondante in Educazione. Alcune riflessioni sull’Evidence-Based Education
Creators: name: D’Agnese, Vasco
Publisher: name: Studi sulla Formazione
Year: 2014

description: This essay provides a critical examination of Education as an Evidence based practice, focusing on three orders of limits: episthemological, ethical, and pragmatical. First of all the epistemology of Evidence based practice is an old one: we know, from Karl Popper to Thomas Kuhn, from Alexandre Koyré to Michel Foucault, from Wittgenstein to Richard Rorty that the logic of scientific discovery is very complex, involving several orders of factors; when we develop a research we can’t never say : “this is an ultimate evidence”. Of course we must go on and try out conclusions. But the way in which we think education, the social and interactive nature of educational process vented serious doubts about the nature of evidence we must accept. Then, Evidence based practice seems to provide a framework to avoid the personal responsibility in choosing one way or another – that’s why it’s so attractive -. In order to pragmatical limits, we argue that we don’t know the whole educational process from the beginning and working only on a preconceived evidence will restrict the possibilities of education and will not work in order to an expansion of opportunities of people who are involved in educational process.

description: Harvard architecture CPU design is common in the embedded world. Examples of Harvard-based architecture devices are the Mica family of wireless sensors. Mica motes have limited memory and can process only very small packets. Stack-based buffer overflow techniques that inject code into the stack and then execute it are therefore not applicable. It has been a common belief that code injection is impossible on Harvard architectures. This paper presents a remote code injection attack for Mica sensors. We show how to exploit program vulnerabilities to permanently inject any piece of code into the program memory of an Atmel AVR-based sensor. To our knowledge, this is the first result that presents a code injection technique for such devices. Previous work only succeeded in injecting data or performing transient attacks. Injecting permanent code is more powerful since the attacker can gain full control of the target sensor. We also show that this attack can be used to inject a worm that can propagate through the wireless sensor network and possibly create a sensor botnet. Our attack combines different techniques such as return oriented programming and fake stack injection. We present implementation details and suggest some counter-measures.

description: Modern video games are extremely complex software systems and, as such, they might suffer from several types of post-release issues. A particularly insidious issue is constituted by drops in the frame rate (i.e., stuttering events), which might have a negative impact on the user experience. Stuttering events are frequently documented in the million of hours of gameplay videos shared by players on platforms such as Twitch or YouTube. From the developers’ perspective, these videos represent a free source of documented “testing activities”. However, especially for popular games, the quantity and length of these videos make impractical their manual inspection.
We introduce HASTE, an approach for the automatic detection of stuttering events in gameplay videos that can be exploited to generate candidate bug reports. HASTE firstly splits a given video into visually coherent slices, with the goal of filtering-out those that not representing actual gameplay (e.g., navigating the game settings). Then, it identifies the subset of pixels in the video frames which actually show the game in action excluding additional elements on screen such as the logo of the YouTube channel, on-screen chats etc. In this way, HASTE can exploit state-of-the-art image similarity metrics to identify candidate stuttering events, namely subsequent frames being almost identical in the pixels depicting the game. We evaluate the different steps behind HASTE on a total of 105 videos showing that it can correctly extract video slices with a 76% precision, and can correctly identify the slices related to gameplay with a recall and precision higher than 77%. Overall, HASTE achieves 71% recall and 89% precision for the identification of stuttering events in gameplay videos.

description: The thermoelectric response of 80-nm-thick strained HgTe films of a three-dimensional topological insulator (3D TI) has been studied experimentally. An ambipolar thermopower is observed where the Fermi energy moves from conducting to the valence bulk band. The comparison between theory and experiment shows that the thermopower is mostly due to the phonon drag contribution. In the region where the 2D Dirac electrons coexist with bulk hole states, the Seebeck coefficient is modified due to 2D electron - 3D hole scattering.

Mellin Moments of the {$O(α_s^3$)} Heavy Flavor Contributions to unpolarized Deep-Inelastic Scattering at $Q^2 \gg m^2$ and Anomalous Dimensions

description: We calculate the $O(α_s^3)$ heavy flavor contributions to the Wilson coefficients of the structure function $F_2(x,Q^2)$ and the massive operator matrix elements (OMEs) for the twist--2 operators of unpolarized deeply inelastic scattering in the region $Q^2 \gg m^2$. The massive Wilson coefficients are obtained as convolutions of massive OMEs and the known light flavor Wilson coefficients. We also compute the massive OMEs which are needed to evaluate heavy flavor parton distributions in the variable flavor number scheme (VFNS) to 3--loop order. All contributions to the Wilson coefficients and operator matrix elements but the genuine constant terms at $O(α_s^3)$ of the OMEs are derived in terms of quantities, which are known for general values in the Mellin variable $N$. For the operator matrix elements $A_{Qg}^{(3)}, A_{qg,Q}^{(3)}$ and $A_{gg,Q}^{(3)}$ the moments $N = 2$ to 10, for $A_{Qq}^{(3), \rm PS}$ to $N = 12$, and for $A_{qq,Q}^{(3), \rm NS}$, $A_{qq,Q}^{(3),\rm PS}$, $A_{gq,Q}^{(3)}$ to N=14 are computed. These terms contribute to the light flavor +-combinations. For the flavor non-singlet terms, we calculate as well the odd moments N=1 to 13, corresponding to the light flavor $-$-combinations. We also obtain the moments of the 3--loop anomalous dimensions, their color projections for the present processes respectively, in an independent calculation, which agree with the results given in the literature.

description: The author argues that it is an important issue in education today to reflect on the training, university and non-professions education and training. We must ask ourselves how and what the size, the theory and practice of research to be a constituent part of the profession of teacher training. The search must then be placed in the same disciplinary teaching of each discipline, in the very way in which we deal with the contents, of whatever kind they are, must pass through a certain style of teaching that identifies the ‘posture’ research in voltage not to go as exhaustive and closed the knowledge that is taught of the qualifying points. The author considers both qualitative and quantitative assessment tools considering how the case studies can be useful to reflect on the emotional scope of the profession of education.

Wall-anchored semiflexible polymer under large amplitude oscillatory shear flow

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The properties of semiflexible polymers tethered by one end to an impenetrable wall and exposed to oscillatory shear flow are investigated by mesoscale simulations. A polymer, confined in two dimensions, is described by a linear bead-spring chain, and fluid interactions are incorporated by the Brownian multiparticle collision dynamics approach. At small strains, the polymers follow the applied flow field. However, at high strain, we find a strongly nonlinear response, with major conformational changes. Polymers are stretched along the flow direction and exhibit U-shaped conformations while following the flow. As a consequence of confinement in the half-space, a frequency doubling in the time-dependent polymer properties appears along the direction normal to the wall.

description: Topological superconductivity is an exotic phenomenon due to the symmetry-protected topological surface state, in which a quantum system has an energy gap in the bulk but supports gapless excitations confined to its boundary. Symmetries including central and time-reversal (TRS), along with their relations with topology, are crucial for topological superconductivity. We report muon spin relaxation/rotation ($μ$SR) experiments on a topological noncentrosymmetric superconductor PbTaSe$_2$ to study its TRS and gap symmetry. Zero-field $μ$SR experiments indicate the absence of internal magnetic field in the superconducting state, consistent with previous $μ$SR results. Furthermore, transverse-field $μ$SR measurements reveals that the superconducting gap of PbTaSe$_2$ is an isotropic three-dimensional fully-gapped single-band. The fully-gapped results can help understand the pairing mechanism and further classify the topological superconductivity in this system.

description: The remarkably high superconducting transition temperature and upper critical field of iron(Fe)-based layered superconductors, despite ferromagnetic material base, open the prospect for superconducting electronics. However, success in superconducting electronics has been limited because of difficulties in fabricating high-quality thin films. We report the growth of high-quality c-axis-oriented cobalt(Co)-doped SrFe2As2 thin films with bulk superconductivity by using an in-situ pulsed laser deposition technique with a 248-nm-wavelength KrF excimer laser and an arsenic(As)-rich phase target. The temperature and field dependences of the magnetization showing strong diamagnetism and transport critical current density with superior Jc-H performance are reported. These results provide necessary information for practical applications of Fe-based superconductors.

description: The purpose of this paper is to examine the important topological properties of the function spaces BC(X,Y) and C(X,Y). Emphasis is given to the relationship between the metrizability of X and the separability of these function spaces. The paper is divided into three major parts: the preliminary definitions and theorems; the relationship between the topological properties of X and BC (X ,Y), for compact X; and the extension of the results of Part II for X not compact and for the case when we have C(X, Y).
Sheared phase-separating binary mixtures with surface diffusion

Year: 2021
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: The phase-separation process of a binary mixture with order-parameter-dependent mobility under shear flow is numerically studied. The ordering is characterized by an alternate stretching and bursting of domains which produce oscillations in the physical observables. The amplitude of such modulations reduce in time when the mobility vanishes in the bulk phase, disfavoring the growth of bubbles coming from bursted domains. We propose two equations for the typical sizes $R_x$ and $R_y$ of domains finding the long-time behaviors $R_x \sim t^{5/4}$ and $R_y \sim t^{1/4}$ in the flow and shear directions, respectively, in the case of surface diffusion. A reduction of the excess viscosity with increasing shear rate is observed in simulations.
IRIDIUM COMPLEXES OF REDOX-ACTIVE LIGANDS: STRUCTURES AND MECHANISMS
Creators: name: Haungs, David A.
Publisher: name: University of Notre Dame
Year: 2023

description: Iminoxolenes and dioxolenes are redox-active ligands whose complex but quantifiable π interactions with metals defy simplistic π-donor/acceptor classifications. Tipsi, an iminoxolene with additional alkyne functionality, and 3,5-di-*tert*-butyl-1,2-benzoquinone react in sequence with an iridium(I) precursor to generate two stereoisomers of (κ2,η2-Tipsi)(3,5-tBu2Cat)IrCl (1a-b).Structural and spectroscopic analyses reveal that the redox-active ligands (especially Tipsi) dominate the π bonding framework, while the alkyne coordinates without significant π donation or backbonding. Its π-innocence is corroborated by ligand substitution with the σ-only pyridine ligand, which forms trans stereoisomers of (κ2-Tipsi)(3,5-tBu2Cat)Ir(py)Cl **(2a–b**) in which the iminoxolene and dioxolene structure and bonding are essentially unchanged. Isomerization from **1a** to **1b** and pyridine addition to the alkyne adducts to generate **2a–b** share common square pyramidal intermediates formed upon alkyne dissociation. Stereochemistry in the Tipsi-dioxolene system is governed by the stability of trans intermediate **3**, which is stabilized relative to the cis square pyramidal alternatives by an additional π bonding interaction.

A similar interaction stabilizes an analogous bis(iminoxolene) complex, (Diso)2IrCl, which quickly reacts with pyridine to establish an equilibrium with *trans*-(Diso)2Ir(py)Cl. Elevated heating produces *cis*-(Diso)2Ir(py)Cl as the thermodynamically favored product, providing a point of contrast with the Tipsi-dioxolene system. Kinetic and computational data suggest a mechanism in which pyridine, by trapping the stable trans (Diso)2IrCl, inhibits formation of the thermodynamic product. This is because isomerization of (Diso)2IrCl, a step with a higher free energy barrier, is necessary to generate the fleeting cis intermediate (Diso)2IrCl\* prior to pyridine associating to form *cis*-(Diso)2Ir(py)Cl. The bis(Diso) system may find practical application through the reduction of (Diso)2IrCl to (Diso)2Ir, a potential hydrogenation catalyst. (Diso)2Ir can react with dihydrogen to form (Diso)2IrH, which selectively hydrogenates organic substrates across weak π bonds. Though kinetic measurements to gauge the favorability of hydrogen uptake are difficult to reproduce, experimental evidence confirms that the process of regenerating (Diso)2IrH from (Diso)2Ir can occur without assistance from iridium(0) nanoparticles, suggesting that a (Diso)2Ir homogeneous hydrogenation catalyst is feasible.

description: (Abridged) Thirty-three objects with possible origins beyond the Kuiper Belt edge, very high inclinations, very large semi-major axes or large perihelion distances were observed to determine their surface colors. All three objects that have been dynamically linked to the inner Oort cloud (Sedna, 2006 SQ372, and 2000 OO67) were found to have ultra-red surfaces (S~25). Ultra-red material is generally associated with rich organics and the low inclination "cold" classical Kuiper Belt objects. The observations detailed here show very red material may be a more general feature for objects kept far from the Sun. The recently discovered retrograde outer Solar System objects (2008 KV42 and 2008 YB3) and the high inclination object (127546) 2002 XU93 show only moderately red surfaces (S~9), very similar to known comets. The extended or detached disk objects, which have large perihelion distances and large eccentricities, are found to have mostly moderately red colors (10 < S < 18). The colors of the detached disk objects, including the dynamically unusual 2004 XR190 and 2000 CR105, are similar to the scattered disk and Plutino populations. Thus the detached and scattered disk likely have a similar mix of objects from the same source regions. Outer classical belt objects, including 1995 TL8, were found to have very red surfaces (18 < S < 30). The "cold" classical belt, outer classical belt and inner Oort cloud appear to be dominated by ultra-red objects (S > 25) and thus don't likely have a similar mix of objects as the scattered disk, detached disk and Trojan populations. A possible trend was found for the detached disk and outer classical belt in that objects with smaller eccentricities have redder surfaces irrespective of inclinations or perihelion distances. There is also a clear trend that objects more distant appear redder.

description: What are the most appropriate ways to activate changes in educational services in order to optimally answer to their institutional mandate in a complex society? This paper answers this question by adopting a organizational perspective that covers interconnected and coordinated learning processes, with all the actors of the educational system (pupils, teachers, parents, managers, administrative staff...) and, in a meta-level, of the system itself. After an excursus on the theories of the organization, useful information for making choices and conscious operational design in a systemic and ecological perspective are given.

description: The Groth field is one of the sky regions that will be targeted by the OTELO (OSIRIS Tunable Filter Emission Line Object) survey in the optical 820 nm and 920 nm atmospheric windows. This field has been observed by AEGIS (All-wavelength Extended Groth strip International Survey) covering the full spectral range, from X-rays to radio waves. Chandra X-ray data with total exposure time of 200ksec are analyzed and combined with optical broadband data of the Groth field in order to study a set of structural parameters of the X-ray emitters and its relation with X-ray properties. We processed the raw, public X-ray data using the Chandra Interactive Analysis of Observations and determined and analyzed different structural parameters in order to produce a morphological classification of X-ray sources. Finally, we analyzed the angular clustering of these sources using 2-point correlation functions. We present a catalog of 340 X-ray emitters with optical counterpart. We obtained the number counts and compared them with AEGIS data. Objects have been classified by nuclear type using a diagnostic diagram relating X-ray-to-optical ratio (X/O) to hardness ratio (HR). Also, we combined structural parameters with other X-ray and optical properties, and found for the first time an anticorrelation between the X/O ratio and the Abraham concentration index which might suggest that early type galaxies have lower Eddington rates than those of late type galaxies. A significant positive angular clustering was obtained from a preliminary analysis of 4 subsamples of the X-ray sources catalog. The clustering signal of the opticaly extended counterparts is similar to that of strongly clustered populations like red and very red galaxies, suggesting that the environment plays an important role in AGN phenomena.

A comprehensive Gaia view of ellipsoidal and rotational red giant binaries

description: The latest Gaia Focused Product Release (FPR) provided variability information for $\sim$1000 long-period red giant binaries, the largest sample to date of this binary type having both photometric and spectroscopic time series observations. We cross-matched the Gaia DR3 measurements with the catalogue of long-period red giant candidates from the Gaia FPR, having photometric and radial velocity variability information. Combined with the photo-geometric distances, the extinction, bolometric magnitude, luminosity, spectroscopic radius and mass were estimated. ELL variables are characterized to be low to intermediate-mass stars, with radii as large as the Roche lobe radius of the binary. Eccentricities tend to be lower for primary stars with smaller radii, as the expected result of tidal circularization. Combined with the orbital properties, estimates for the minimum mass of the companion agree with the scenario of a low-mass compact object as the secondary star. There are at least 14 ELL binaries with orbital periods and masses compatible with model predictions for Type Ia SN progenitors. For the rotational variables, their orbital periods, enhanced chromospheric activity, smaller radii and low mass point to a different type of binaries than the original ELL sample. The velocity dispersion is much higher in ELL than in rotational binaries, probably indicating older/younger dynamical ages. The enhanced [$α$/Fe] abundances for some of the ELL binaries resemble the population of young $α$-rich binaries in the thick disk. An episode of mass transfer in those systems may have produced the enhanced $α$ abundances, and the enhanced [Ce/Fe] abundances reported in a few ELL binaries. Luminosities, radii and masses were derived for 243 ELL and 39 rotational binary candidates, the largest Galactic sample of these variables, having chemo-dynamical and physical parameterization.

La società educante: una rilettura pedagogica dell'Odissea
Creators: name: Bruni, Elsa M.
Publisher: name: Studi sulla Formazione
Year: 2014

description: The value of the Greek man is measured by his social function: he is considered to be completely at the service of his community. In the same way, the poet, like the philosopher and the orator, plays the role of educator. The case of Homer is significant, in this regard. The most important educator of ancient Greece, Homer turned Achilles into the very ideal of humanness and drew up an educational model which mirrored the aristocratic ethic of archaic Hellenism. This article offers a pedagogical interpretation of The Odyssey retracing the main tenets of the pedagogical awareness which shaped the Western model of education. On this theoretical basis, the author underlines, in the transition from The Iliad to The Odyssey, the importance of Odysseus’s role in the development of a new human and educational ideal – one in which the ancient notion of virility absorbs values pertaining to the hero’s mental and moral traits.

Exact ground states and correlation functions of chain and ladder models of interacting hardcore bosons or spinless fermions

description: By removing one empty site between two occupied sites, we map the ground states of chains of hardcore bosons and spinless fermions with infinite nearest-neighbor repulsion to ground states of chains of hardcore bosons and spinless fermions without nearest-neighbor repulsion respectively, and ultimately in terms of the one-dimensional Fermi sea. We then introduce the intervening-particle expansion, where we write correlation functions in such ground states as a systematic sum over conditional expectations, each of which can be ultimately mapped to a one-dimensional Fermi-sea expectation. Various ground-state correlation functions are calculated for the bosonic and fermionic chains with infinite nearest-neighbor repulsion, as well as for a ladder model of spinless fermions with infinite nearest-neighbor repulsion and correlated hopping in three limiting cases. We find that the decay of these correlation functions are governed by surprising power-law exponents.

Defect-related photoluminescence of hexagonal boron nitride

description: Photoluminescence of polycrystalline hexagonal boron nitride (hBN) was measured by means of time- and energy-resolved spectroscopy methods. The observed bands are related to DAP transitions, impurities and structural defects. The excitation of samples by high-energy photons above 5.4 eV enables a phenomenon of photostimulated luminescence (PSL), which is due to distantly trapped CB electrons and VB holes. These trapped charges are metastable and their reexcitation with low-energy photons results in anti-Stockes photoluminescence. The comparison of photoluminescence excitation spectra and PSL excitation spectra allows band analysis that supports the hypothesis of Frenkel-like exciton in hBN with a large binding energy.
title: Multicollinearity and the Estimation of Regression Coefficients
Creators: name: Teed, John Charles
Publisher: name: Utah State University
Year: 1978

description: The precision of the estimates of the regression coefficients in a regression analysis is affected by multicollinearity. The effect of certain factors on multicollinearity and the estimates was studied. The response variables were the standard error of the regression coefficients and a standarized statistic that measures the deviation of the regression coefficient from the population parameter.
The estimates are not influenced by any one factor in particular, but rather some combination of factors. The larger the sample size, the better the precision of the estimates no matter how "bad" the other factors may be.
The standard error of the regression coefficients proved to be the best indication of estimation problems.
Tethered Semiflexible Polymer under Large Amplitude Oscillatory Shear

description: The properties of a semiflexible polymer with fixed ends exposed to oscillatory shear flow are investigated by simulations. The two-dimensionally confined polymer is modeled as a linear bead-spring chain, and the interaction with the fluid is described by the Brownian multiparticle collision dynamics approach. For small shear rates, the tethering of the ends leads to a more-or-less linear oscillatory response. However, at high shear rates, we found a strongly nonlinear reaction, with a polymer (partially) wrapped around the fixation points. This leads to an overall shrinkage of the polymer. Dynamically, the location probability of the polymer center-of-mass position is largest on a spatial curve resembling a limaçon, although with an inhomogeneous distribution. We found shear-induced modifications of the normal-mode correlation functions, with a frequency doubling at high shear rates. Interestingly, an even-odd asymmetry for the Cartesian components of the correlation functions appears, with rather similar spectra for odd $x$- and even $y$-modes and vice versa. Overall, our simulations yielded an intriguing nonlinear behavior of tethered semiflexible polymers under oscillatory shear flow.

description: Dicke states are states of a collection of particles which have been under active investigation for several reasons. One reason is that the decay rates of these states can be quite different from a set of independently evolving particles. Another reason is that a particular class of these states are decoherence-free or noiseless with respect to a set of errors. These noiseless states, or more generally subsystems, can avoid certain types of errors in quantum information processing devices. Here we provide a method for calculating invariants of systems of particles undergoing collective motions. These invariants can be used to determine a complete set of commuting observables for a class of Dicke states as well as identify possible logical operations for decoherence-free/noiseless subsystems. Our method is quite general and provides results for cases where the constituent particles have more than two internal states.
