Overview

Préface de la Micro:bit Educational Foundation Maîtriser la carte micro:bit en 40 activités Mise au point au Royaume-Uni à l'initiative de la BBC, la carte micro:bit est un ordinateur de poche entièrement programmable qui constitue un phénomène mondial depuis son lancement en 2016. Ses qualités pédagogiques, son matériel particulièrement performant, sa facilité de programmation et son coût modique contribuent à cette réussite. Conçu à l'origine pour un usage éducatif, ce nano-ordinateur permet d'initier les élèves au codage et au pilotage de petits montages électroniques. Avec ses 40 activités ludiques, ce livre vous fera découvrir toutes les possibilités et qualités de cette carte, en la programmant facilement avec le logiciel d'approche visuelle MakeCode, très proche de Scratch. Chaque activité va à l'essentiel, en présentant la problématique, voire un algorigramme, et un exemple de programme. Cet ouvrage est organisé en deux parties : la première permet de découvrir les fonctions simples de la carte micro:bit ; la seconde propose des activités plus avancées, qui s'appuient notamment sur des modules complémentaires comme les modules Grove. À qui s'adresse ce livre ? - Aux enseignants et à leurs élèves de primaire, collège, lycée - Aux makers, geeks, roboticiens, Fab Labs...
Threshold voltage instability by charge trapping effects in the gate region of p-GaN HEMTs

description: In this work, the threshold voltage instability of normally-off p-GaN high electron mobility transistors (HEMTs) has been investigated by monitoring the gate current density during device on-state. The origin of the gate current variations under stress has been ascribed to charge trapping occurring at the different interfaces in the metal/p-GaN/AlGaN/GaN system. In particular, depending on the stress bias level, electrons (VG < 6 V) or holes (VG > 6 V) are trapped, causing a positive or negative threshold voltage shift {DVTH, respectively. By monitoring the gate current variations at different temperatures, the activation energies associated to the electrons and holes trapping could be determined and correlated with the presence of nitrogen (electron traps) or gallium (hole traps) vacancies. Moreover, the electrical measurements suggested the generation of a new electron-trap upon long-time bias stress, associated to the creation of crystallographic dislocation-like defects extending across the different interfaces (p-GaN/AlGaN/GaN) of the gate stack.
Project VeSElkA: Analysis of Balmer line profiles in slowly rotating chemically peculiar stars

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

subject: 85-02

description: We present results for the estimation of gravity, effective temperature, and radial velocity of poorly studied chemically peculiar stars recently observed with the spectropolarimeter Echelle SpectroPolarimetric Device for Observations of Stars at the Canada-France-Hawaii Telescope in the frame of the Vertical Stratification of Element Abundances project. The effective temperature and surface gravity values are determined for the very first time for four of the stars from our sample (HD23878, HD83373, HD95608, and HD164584). Grids of stellar atmosphere models with the corresponding fluxes have been calculated using version 15 of the PHOENIX code for effective temperatures in the range of 5000-15,000 K, for the logarithm of surface gravities in the range of 3.0-4.5 and for the metallicities from -1.0 to +1.5. We used these fluxes to fit the Balmer line profiles employing the code FITSB2 that produces estimates of the effective temperature, gravity, and radial velocity for each star. When possible, our results are compared to those previously published. The physical characteristics of 16 program stars are discussed with the future aim to study the abundance anomalies of chemical species and the possible vertical abundance stratification in their stellar atmosphere.

Counterdiabatic Reverse Annealing
Creators: name: Passarelli, Gianluca

Publisher: name: arXiv
Year: 2022
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We present Counterdiabatic Reverse Annealing, a novel quantum annealing protocol that extends the range of application of reverse annealing to the previously inaccessible short-time domain. This is achieved by exploiting approximate counterdiabatic driving expanded in low-order nested commutators. In this work, we offer a comparative study of the performance of this new technique to that of unassisted reverse annealing in terms of metrics such as the ground-state fidelity and the time to solution. We provide a quantitative measure of the energetic cost of counterdiabatic reverse annealing and show that significant improvements are possible even using local counterdiabatic potentials, paving the way toward the experimental implementation in near-term quantum devices.

Benchmarking NLopt and state-of-art algorithms for Continuous Global Optimization via Hybrid IACO$_\mathbb{R}$

description: This paper presents a comparative analysis of the performance of the Incremental Ant Colony algorithm for continuous optimization ($IACO_\mathbb{R}$), with different algorithms provided in the NLopt library. The key objective is to understand how the various algorithms in the NLopt library perform in combination with the Multi Trajectory Local Search (Mtsls1) technique. A hybrid approach has been introduced in the local search strategy by the use of a parameter which allows for probabilistic selection between Mtsls1 and a NLopt algorithm. In case of stagnation, the algorithm switch is made based on the algorithm being used in the previous iteration. The paper presents an exhaustive comparison on the performance of these approaches on Soft Computing (SOCO) and Congress on Evolutionary Computation (CEC) 2014 benchmarks. For both benchmarks, we conclude that the best performing algorithm is a hybrid variant of Mtsls1 with BFGS for local search.

Generating Functions for Giant Graviton Bound States

Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We construct generating functions for operators dual to systems of giant gravitons with open strings attached. These operators have a bare dimension of order $N$ so that the usual methods used to solve the planar limit are not applicable. The generating functions are given as integrals over auxiliary variables, which implement symmetrization and antisymmetrization of the indices of the fields from which the operator is composed. Operators of a good scaling dimension (eigenstates of the dilatation operator) are known as Gauss graph operators. Our generating functions give a simple construction of the Gauss graph operators which were previously obtained using a Fourier transform on a double coset. The new description provides a natural starting point for a systematic ${1\over N}$ expansion for these operators as well as the action of the dilatation operator on them, in terms of a saddle point evaluation of their integral representation.

description: We analyze recent heat capacity measurements in herbertsmithite $\rm ZnCu_3(OH)_6Cl_2$ single crystal samples subjected to strong magnetic fields. We show that the temperature dependence of specific heat $C_{mag}$ formed by quantum spin liquid at different magnetic fields $B$ resembles the electronic heat capacity $C_{el}$ of the HF metal $\rm YbRh_2Si_2$. We demonstrate that the spinon effective mass $M^*_{mag}\propto C_{mag}/T$ exhibits a scaling behavior like that of $C_{el}/T$. We also show that the recent measurements of $C_{mag}$ are compatible with those obtained on powder samples. These observations allow us to conclude that $\rm ZnCu_3(OH)_6Cl_2$ holds a stable strongly correlated quantum spin liquid, and a possible gap in the spectra of spinon excitations is absent even under the application of very high magnetic fields of 18 T.

Overview

En pleine Révolution culturelle, le pouvoir chinois construit une base militaire secrète destinée à abriter un programme de recherche de potentielles civilisations extraterrestres. Ye Wenjie, une jeune astrophysicienne en cours de "rééducation", parvient à envoyer dans l'espace un message contenant des informations sur la civilisation humaine. Le signal est intercepté par les Trisolariens, qui s'apprêtent à abandonner leur planète mère, située à quatre années-lumière de la Terre et menacée d'un effondrement gravitationnel provoqué par les mouvements chaotiques des trois soleils de son système. En raison de la distance, Ye Wenjie met près de huit ans à recevoir la réponse des Trisolariens. Elle tient désormais entre ses mains rien de moins que le destin de l'espèce humaine. Hugo 2015 du meilleur roman, Le Problème à trois corps est le premier volume d'une trilogie culte d'une ambition folle.

Solvable groups, free divisors and nonisolated matrix singularities II: Vanishing topology
Creators: name: Pike, Brian
name: Damon, James
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: In this paper we use the results from the first part to compute the vanishing topology for matrix singularities based on certain spaces of matrices. We place the variety of singular matrices in a geometric configuration of free divisors which are the “exceptional orbit varieties” for representations of solvable groups. Because there are towers of representations for towers of solvable groups, the free divisors actually form a tower of free divisors
Fast parametric two-qubit gate for highly detuned fixed-frequency superconducting qubits using a double-transmon coupler

Year: 2022
Subjects: subject: Quantum Physics (quant-ph)

subject: FOS: Physical sciences

description: High-performance two-qubit gates have been reported with superconducting qubits coupled via a single-transmon coupler (STC). Most of them are implemented for qubits with a small detuning since reducing residual $ZZ$ coupling for highly detuned qubits by an STC is challenging. In terms of the frequency crowding and crosstalk, however, highly detuned qubits are desirable. Here, we numerically demonstrate a high-performance parametric gate for highly detuned fixed-frequency qubits using a recently proposed tunable coupler called a double-transmon coupler (DTC). Applying an ac flux pulse, we can perform a maximally entangling universal gate ($\sqrt{\rm iSWAP}$) with an average fidelity over 99.99$\%$ and a short gate time of about 24 ns. This speed is comparable to resonance-based gates for slightly detuned tunable qubits. Moreover, using a dc flux pulse alternatively, we can achieve another kind of entangling gate called a CZ gate with an average fidelity over 99.99$\%$ and a gate time of about 18 ns. Given the frexibility and feasible settings, we can expect that the DTC will contribute to realizing a high-performance quantum computer in the near future.

description: Targeted advertising on online social platforms has become increasingly relevant in the political marketing toolkit. Monitoring political advertising is crucial to ensure accountability and transparency of democratic processes. Leveraging Meta public library of sponsored content, we study the extent to which political ads were delivered on Facebook and Instagram in the run up to 2022 Italian general election. Analyzing over 23 k unique ads paid by 2.7 k unique sponsors, with an associated amount spent of 4 M EUR and over 1 billion views generated, we investigate temporal, geographical, and demographic patterns of the political campaigning activity of main coalitions. We find results that are in accordance with their political agenda and the electoral outcome, highlighting how the most active coalitions also obtained most of the votes and showing regional differences that are coherent with the (targeted) political base of each group. Our work raises attention to the need for further studies of digital advertising and its implications for individuals' opinions and choices.

Probing General Relativity in galactic scales at z $\sim0.3$

Publisher: name: arXiv
Year: 2022
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

subject: FOS: Physical sciences

description: General Relativity (GR) has been successfully tested mainly at Solar system scales; however, galaxy-scale tests have become popular in the last few decades. In this work, we investigate the $η_\text{PPN}$ parameter, which is commonly defined by the ratio of two scalar potentials that appears in the cosmological linearly perturbed metric. Under the assumption of GR and a vanish anisotropic stress tensor, $η_\text{PPN}= 1$. Using ALMA, HST, and VLT/MUSE data, we combine mass measurements, using gravitational lensing and galactic dynamics, for the SDP.81 lens galaxy ($z = 0.299$) to constrain $η_\text{PPN}$. By using a flexible and self-consistent mass profile, our fiducial model takes into account the contribution of the stellar mass and a dark matter halo to reconstruct the lensed galaxy and the spatially-resolved stellar kinematics. We infer, after accounting for systematic uncertainties related to the mass model, cosmology and kinematics, $η_{\text{PPN}} = 1.13^{+0.03}_{-0.03}\pm0.20\,(\text{sys})$, which is in accordance with GR predictions. Better spectroscopy data are needed to push the systematics down and bring the uncertainty to the percentage level since our analysis shows that the main source of the systematics is related to kinematics, which heavily depends on the signal-to-noise ratio of the spectra.

Assessment of 21st Century Competencies Science Education Lecturers Possess in Universities in Enugu State, Nigeria
Creators: name: Veronica, Chinonyelum Ude

Publisher: name: GO JOURNAL
Year: 2024
Subjects: 21st Century competencies, science education, lecturers, gender, universities

description: This study investigated 21st-century competencies possessed by science education lecturers at the University of Nigeria Nsukka and Godfrey Okoye University Enugu. One research question and three null hypotheses guided the study, adopting a descriptive survey research design. The sample for the study comprised 67 Faculty of Science Education lecturers at the University of Nigeria Nsukka and Godfrey Okoye University Enugu. A simple random sampling technique was used to select the sample. Data was collected using a 20-item 21st-century competency questionnaire developed by the researchers. The instrument was validated by three validators in educational measurement and evaluation at the Faculty of Education, University of Nigeria Nsukka. A 0.79 coefficient of internal consistency index was for the instrument using Cronbach Alpha. The collected data were analyzed using frequency, percentage, mean, standard deviation, t-test, and ANOVA statistics. Findings revealed that communication and collaboration skills are possessed by Science Education lecturers to a high extent, whereas learning and innovation skills, information literacy skills, digital literacy skills, and life career skills are possessed to a low extent. Also, there was a significant difference in the 21st-century competencies of science education lecturers based on gender, experience, and qualification. The study concluded that 21st-century competencies are vital for lecturers to thrive in modern society and recommends that tertiary institutions organize in-service hands-on workshops to teach lecturers 21st-century competencies; and lecturers should see private avenues to improve their 21st-century skills

description: We propose an experimental protocol to study $p$-wave superfluidity in a spin-polarized cold Fermi gas tuned by an $s$-wave Feshbach resonance. A crucial ingredient is to add a quasi-1D optical lattice and tune the fillings of two spins to the $s$ and $p$ band, respectively. The pairing order parameter is confirmed to inherit $p$-wave symmetry in its center-of-mass motion. We find that it can further develop into a state of unexpected $π$-phase modulation in a broad parameter regime. Measurable quantities are calculated, including time-of-flight distributions, radio-frequency spectra, and in situ phase-contrast imaging in an external trap. The $π$-phase $p$-wave superfluid is reminiscent of the $π$-state in superconductor-ferromagnet heterostructures but differs in symmetry and origin. If observed, it would represent another example of $p$-wave pairing, first discovered in He-3 liquids.

description: The explosions of Karymsky volcano often produce signals containing a sequence of repeating pulses recorded on acoustic and seismic sensors, known as chugging. The amplitudes of these pulses correlate with the time interval between pulses. For a given measured acoustic pressure, seismic amplitudes take on arbitrary values up to a specific, empirically determined threshold. Conversely, events with a small seismic amplitude yielded acoustic waves with large variations and large-amplitude seismic events corresponded to large acoustic waves. These observations are not consistent with a source modelled by a resonating conduit. Rather, a model consisting of a sequence of discrete pulses explains the data and provides a framework for understanding the dynamics of degassing at the vent. The physical model for chugging involves a time-varying narrowing vent where gasses are released in a series of oscillations which appear to be harmonic but instead are modelled as short-term transients, or discrete pulses, suggestive of choked flow.

Overview

Il a fort longtemps, un vaillant chevalier combattait les méchants, tuait des dragons et sauvait les demoiselles en détresse. Il se croyait bon, gentil et plein d'amour. Il était très fier de sa magnifique armure qui brillait de mille feux, et ne la quittait jamais, même pour dormir. Seulement, un beau jour, en voulant l'enlever, il se retrouva coincé... Ainsi commença pour lui une quête initiatique, à la recherche de sa véritable identité, au gré de rencontres insolites et d'épreuves riches d'enseignement. En parvenant au "Sommet de la Vérité", il deviendra alors ce qu'il n'avait jamais cessé d'être, un homme au coeur pur, libre de toute illusion et de peur. Cette nouvelle quête du Graal, d'un humour délicieux, fait partie de ces "grands petits livres" comme Le Petit Prince et Jonathan Livingston le goéland. La limpidité, la profondeur du Chevalier à l'armure rouillée, qui parle au coeur et à l'âme, en font un conte d'une portée universelle.
An inversion scheme to model subsurface fracture systems using shear wave splitting polarization and delay time observations simultaneously

description: Shear wave splitting polarization () and delay time (Δ) observations are used to invert for fracture orientation and intensity of fracturing, simultaneously. By addressing the different levels of uncertainty involved in measurements of these two parameters, as well as their dissimilar relationships to fracture configuration, we have developed an inversion algorithm which reduces the primary double-response inversion to two connected single-response ones. We show that its inherent non-linearity complicates this problem, which therefore requires a more sophisticated attack than conventional inversion schemes. It will be shown that the construction of residue function contours in the model plane and the generation of surrogate data by simulation process are essential to this approach. We illustrate the capabilities of this technique by inverting shear wave splitting data from The Geysers geothermal reservoir in California. In principle the method should be useful for characterizing fractured reservoirs, whether geothermal or hydrocarbon.
Crack-induced anisotropy models in The Geysers geothermal field

description: High quality observations of shear-wave anisotropy in the shallow crust have allowed us to detect subsurface crack systems in the NW and the SE Geysers geothermal fields, CA. Shear-wave splitting (SWS) parameters, fast shear-wave polarizations (φ) and time delays (δt), are highly sensitive to the anisotropic fabric of the medium through which shear-waves propagate and constitute the basic dataset to invert for 3-D crack geometry and crack density in the subsurface. Variation and asymmetry patterns in φ and δt observations, plotted in equal-area projections as a function of ray azimuth and incident angle, are essential in the determination of crack strike and dip, crack aspect ratio, and crack density. Inversion results show that the most common patterns of fracture-induced anisotropy in the NW Geysers can be simulated by horizontally transversely isotropic (HTI) media or rocks with vertical (to steeply-dipping) systems of parallel cracks which strike subparallel to the N-to-NE direction of maximum compressive stress. On the other hand, modelled fracture systems in the SE Geysers strike both NE and NW. Percentages of shear-wave velocity anisotropy average about 4 per cent in The Geysers. Deviations from horizontal transverse isotropy conditions are modelled with non-vertically dipping crack systems or with intersecting crack systems. The discussion of specific inversion examples exposes problems related to seismic ray coverage within the shear-wave window, non-uniqueness of crack-induced anisotropy models, and complementarity between polarization and time delay data.
X-ray Fading and Expansion in the "Miniature Supernova Remnant" of GK Persei

description: We report on a second epoch of Chandra X-ray imaging spectroscopy of the spatially-resolved old nova remnant GK Persei. An ACIS-S3 observation of 97.4 ks was conducted in November 2013 after a lapse of 13.8 years from the last visit in 2000. The X-ray emitting nebula appeared more faint and patchy compared with the first epoch. The flux decline was particularly evident in fainter regions and the mean decline was 30-40 % in the 0.5-1.2 keV energy band. A typical expansion of the brightest part of the remnant was 1.9 arcsec, which corresponds to an expansion rate of 0.14 arcsec yr^{-1}. The soft X-ray spectra extracted from both the 2000 and 2013 data can be explained by a non-equilibrium ionization collisional plasma model convolved with interstellar absorption, though do not allow us to constrain the origin of the flux evolution. The plasma temperature has not significantly evolved since the 2000 epoch and we conclude that the fading of the X-ray emission is due largely to expansion. This implies that recent expansion has been into a lower density medium, a scenario that is qualitatively consistent with the structure of the circumstellar environment photographed soon after the initial explosion more than a century ago. Fainter areas are fading more quickly than brighter areas, indicating that they are fainter because of a lower ambient medium density and consequently more rapid expansion.
