description: Fonvalmed administra los recursos de la contribución por valorización en la ciudad de Medellín, los cuales son usados para la ejecución proyectos de infraestructura en la ciudad. De aquí se desprende un rol importante para el Fondo, ser un supervisor de proyectos. Este rol puede fortalecerse estandarizando, controlando, midiendo y mejorando las mejores prácticas de gestión de proyectos basadas en los estándares del PMI. El trabajo desarrolla una metodología que tiene como objetivo recopilar información detallada a través de entrevistas con expertos, el modelo OPM3 para evaluar la madurez de la organización y otras herramientas que brinden información sobre áreas específicas de mejora y prácticas de gestión de proyectos que logren aumentar los niveles de madurez en los procesos de la entidad. Al Fonvalmed ya contar con algunas herramientas de software para la transformación digital, y para no incurrir en costos adicionales, se recomienda usar la tecnología existente de manera efectiva y extender su uso para aprovecharla en la gestión de los proyectos

From this comes an important role for the Fund, to be a project supervisor. This role can be strengthened by standardizing, monitoring, measuring, and improving project management best practices based on PMI standards. The work develops a methodology that aims to collect detailed information through interviews with experts, the OPM3 model to assess the maturity of the organization and other tools that provide information on specific areas of improvement and project management practices that manage to increase profits. maturity levels in the entity's processes. As Fonvalmed already has some software tools for digital transformation, and in order not to incur additional costs, it is recommended to use existing technology effectively and extend its use to take advantage of it in project management.

description: We study the tidal response of a superfluid neutron star in a binary system, focussing on Newtonian models with superfluid neutrons present throughout the star's core and the inner crust. Within the two-fluid formalism, we consider the main aspects that arise from the presence of different regions inside the star, with particular focus on the various interfaces. Having established the relevant theory, we determine the tidal excitation of the most relevant oscillation modes during binary inspiral. Our results suggest that superfluid physics has a negligible impact on the static tidal deformation. The overwhelming contribution to the Love number is given by, as for normal matter stars, the ordinary fundamental mode (f-mode). Strong entrainment, here described by a phenomenological expression which mimics the large effective neutron mass expected at the bottom of the crust, is shown to have significant impact on the superfluid modes, but our results for the dynamical tide are nevertheless similar to the static limit: the fundamental modes are the ones most significantly excited by the tidal interaction, with the ordinary f-mode dominating the superfluid one. We also discuss the strain built up in the star's crust during binary inspiral, showing that the superfluid f-mode may (depending on entrainment) reach the limit where the crust breaks, although it does so after the ordinary f-mode. Overall, our results suggest that the presence of superfluidity may be difficult to establish from binary neutron star gravitational-wave signals.

description: Since the onset of the COVID-19 pandemic, vaccines have been an important topic in public discourse. The discussions around vaccines are polarized as some see them as an important measure to end the pandemic, and others are hesitant or find them harmful. This study investigates posts related to COVID-19 vaccines on Twitter and focuses on those which have a negative stance toward vaccines. A dataset of 16,713,238 English tweets related to COVID-19 vaccines was collected covering the period from March 1, 2020, to July 31, 2021. We used the Scikit-learn Python library to apply a support vector machine (SVM) classifier to identify the tweets with a negative stance toward the COVID-19 vaccines. A total of 5,163 tweets were used to train the classifier, out of which a subset of 2,484 tweets were manually annotated by us and made publicly available. We used the BERTtopic model to extract and investigate the topics discussed within the negative tweets and how they changed over time. We show that the negativity with respect to COVID-19 vaccines has decreased over time along with the vaccine roll-outs. We identify 37 topics of discussion and present their respective importance over time. We show that popular topics consist of conspiratorial discussions such as 5G towers and microchips, but also contain legitimate concerns around vaccination safety and side effects as well as concerns about policies. Our study shows that even unpopular opinions or conspiracy theories can become widespread when paired with a widely popular discussion topic such as COVID-19 vaccines. Understanding the concerns and the discussed topics and how they change over time is essential for policymakers and public health authorities to provide better and in-time information and policies, to facilitate vaccination of the population in future similar crises.

description: We investigate the symmetry resolution of entanglement in the presence of long-range couplings. To this end, we study the symmetry-resolved entanglement entropy in the ground state of a fermionic chain that has dimerised long-range hoppings with power-like decaying amplitude -- a long-range generalisation of the Su-Schrieffer-Heeger model. This is a system that preserves the number of particles. The entropy of each symmetry sector is calculated via the charged moments of the reduced density matrix. We exploit some recent results on block Toeplitz determinants generated by a discontinuous symbol to obtain analytically the asymptotic behaviour of the charged moments and of the symmetry-resolved entropies for a large subsystem. At leading order we find entanglement equipartition, but comparing with the short-range counterpart its breaking occurs at a different order and it does depend on the hopping amplitudes.

description: Dark Energy Spectroscopic Instrument (DESI) will construct a large and precise three-dimensional map of our Universe. The survey effective volume reaches $\sim20\Gpchcube$. It is a great challenge to prepare high-resolution simulations with a much larger volume for validating the DESI analysis pipelines. \textsc{AbacusSummit} is a suite of high-resolution dark-matter-only simulations designed for this purpose, with $200\Gpchcube$ (10 times DESI volume) for the base cosmology. However, further efforts need to be done to provide a more precise analysis of the data and to cover also other cosmologies. Recently, the CARPool method was proposed to use paired accurate and approximate simulations to achieve high statistical precision with a limited number of high-resolution simulations. Relying on this technique, we propose to use fast quasi-$N$-body solvers combined with accurate simulations to produce accurate summary statistics. This enables us to obtain 100 times smaller variance than the expected DESI statistical variance at the scales we are interested in, e.g. $k < 0.3\hMpc$ for the halo power spectrum. In addition, it can significantly suppress the sample variance of the halo bispectrum. We further generalize the method for other cosmologies with only one realization in \textsc{AbacusSummit} suite to extend the effective volume $\sim 20$ times. In summary, our proposed strategy of combining high-fidelity simulations with fast approximate gravity solvers and a series of variance suppression techniques sets the path for a robust cosmological analysis of galaxy survey data.

Critical-layer instability of shallow water magnetohydrodynamic shear flows

Year: 2022
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: In this paper, the instability of shallow water shear flow with a sheared parallel magnetic field is studied. Waves propagating in such magnetic shear flows encounter critical levels where the phase velocity relative to the basic flow $c-U(y)$ matches the Alfvén wave velocities $\pm B(y)/\sqrt{μρ}$, based on the local magnetic field $B(y)$, the magnetic permeability $μ$ and the mass density of the fluid $ρ$. It is shown that when the two critical levels are close to each other, the critical layer can generate an instability. The instability problem is solved, combining asymptotic solutions at large wavenumbers and numerical solutions, and the mechanism of instability explained using the conservation of momentum. For the shallow water MHD system, the paper gives the general form of the local differential equation governing such coalescing critical layers for any generic field and flow profiles, and determines precisely how the magnetic field modifies the purely hydrodynamic stability criterion based on the potential vorticity gradient in the critical layer. The curvature of the magnetic field profile, or equivalently the electric current gradient, $J' = - B''/μ$ in the critical layer is found to play a complementary role in the instability.

description: Summary

A demographic increase is clearly documented by the presence of increasingly larger huts and villages in Sardinia during the second phase  and the beginning of the Final Bronze Age. At the end of the Final Bronze Age, instead, many nuraghi are abandoned in almost the entire Sardinian territory, perhaps because of structural damages of the upper parts. 4800 faunal remains have been found in the north tower of S. Antine nuraghe near Torralba (SS). In particular a sort of  water well-cistern has been identified, which was abandoned and disused in the final Bronze age. The structure seems to be ritualized after its abandonment. At the bottom of the cistern a votive vessel was found. Furthermore,  the water well is sealed with a ring of stones forming a very narrow mouth. Outside the cistern, several uneven paving and numerous pottery were found. This finds allow us to reconstruct all the phases of the nuraghe from the Middle Bronze Age to the first phase of the Iron Age. The zooarchaeological research tries to highlight any differences between the various phases of the monument. Particularly, the attention is focused on the transition between the Bronze Age and Iron Age. Is possible, in fact, that the structure has been abandoned or reused in this period.

description: The Training Work Package (WP4) of the PRACE Fifth Implementation Phase (PRACE-5IP) project is responsible for the training activities of PRACE. In addition to the extensive programme of face-to-face training delivered by the PRACE Advanced Training Centres (PATCs) and PRACE Training Centres (PTCs), the training activities also include the On-demand training events, a series of online training offerings such as the Massive Open Online Courses (MOOCs), the training code repository (CodeVault) and the training portal. This deliverable is a report of all the PRACE-5IP training activities during the initial 15 months of the project.
 PRACE-5IP continued the training activities of PRACE-4IP starting from February 2017. Between February 2017 and April 2018, the six PATCs delivered 103 courses, 290 course-days with 2,396 participants, while the four PTCs delivered 12 courses, 21 course-days with 351 participants. The feedback responses received have been overwhelmingly positive (8.5/10 average overall rating for PATC courses).
 Similarly, the PRACE Seasonal Schools in PRACE-5IP have been carefully selected via a formal selection process. The Seasonal Schools scheduled for this reporting period, namely the Autumn School 2017 in Gdańsk, Poland and the Winter Seasonal School 2018 in Bratislava, Slovak Republic, attracted 39 attendees in total, and obtained high overall ratings.
 In addition, WP4 continued the collaboration with the Centres of Excellence (CoEs) where a number of On-demand events were organised. Finally, WP4 co-organised the 2017 International Summer School on HPC Challenges in Computational Sciences in Boulder, Colorado, United States of America, from 25-30 June 2017.
 All forms of face-to-face and online training are complementary. They contribute to the success of the PRACE training programme, and should be continued in future PRACE HPC training activities. In accordance with the PRACE-5IP goals, the majority of training events also address industrial users, and motivate them by showing the importance and benefits of HPC for the practice.

Nous avons utilisé des régressions en données de panel avec la méthode d’estimation à effets aléatoires pour les 6 pays de la CEMAC sur la période de 1990 à 2020, les résultats obtenus montrent que l’éducation a un effet positif et significatif sur le développement industriel. En ce qui concerne la démocratie, elle a un effet négatif sur le développement industriel, prise de manière isolée. Toutefois, il apparait que l’effet conjugué de la démocratie et l’éducation sur le développement industriel est en partie positif et significatif. Il convient de dire que, l’éducation est un facteur fondamental au développement industriel. Par conséquent, il est nécessaire que des politiques incitatives soient mises en place pour encourager l’alphabétisation et la scolarisation des populations et plus précisément dans les formations en sciences de l'ingénierie surtout au niveau tertiaire. Un accent particulier devra être mis également sur l’amélioration de la gouvernance afin de la rendre beaucoup plus démocratique.

description: The study investigates the impact of downsizing layoffs on the profitability of construction industries listed in BSE India. In India, construction industries have adopted downsizing long back in the organization to improve the firms performance. For the purpose of the study, Secondary data of 15 Construction companies listed in BSE India have been considered for a period of 10 years from FY.2010 to FY2019. Data has been taken from the companys official website. The variable considered for the analysis is Other Expenses, Returns on Net Worth, Employee Expenses, Number of Employees, and Profit Per Employee. The study has used the Co-integration test to see co-integration between the variables, Ordinary Least Square (OLS) and Vector Auto Regression (VAR) the model used for estimating the impact of downsizing on the profitability of construction companies. OLS and VAR model has been used to draw a conclusion based on the P values and R square. From the result, it can be concluded that, Expect Profit Per Employees are the downsizing variable that has no significant impact on the profitability of the firms performance. Whereas the other Downsizing variables Employee Expenses and the Number of Employee has a significant impact on the profitability of the firms performance

description: A new class of atomic interferences using ultra-narrow optical transitions are pushing quantum engineering control to a very high level of precision for a next generation of sensors and quantum gate operations. In such context, we propose a new quantum engineering approach to Ramsey-Bordé interferometry introducing multiple composite laser pulses with tailored pulse duration, Rabi field amplitude, frequency detuning and laser phase-step. We explore quantum metrology with hyper-Ramsey and hyper-Hahn-Ramsey clocks below the $10^-18$ level of fractional accuracy by a fine tuning control of light excitation parameters leading to spinor interferences protected against light-shift coupled to laser-probe field variation. We review cooperative composite pulse protocols to generate robust Ramsey-Bordé, Mach-Zehnder and double-loop atomic sensors shielded against measurement distortion related to Doppler-shifts and light-shifts coupled to pulse area errors. Fault-tolerant auto-balanced hyper-interferometers are introduced eliminating several technical laser pulse defects that can occur during the entire probing interrogation protocol. Quantum sensors with composite pulses and ultra-cold atomic sources should offer a new level of high accuracy in detection of acceleration and rotation inducing phase-shifts, a strong improvement in tests of fundamental physics with hyper-clocks while paving the way to a new conception of atomic interferometers tracking space-time gravitational waves with a very high sensitivity.

description: N-body simulations and trajectory analysis rely on the calculation of attributes that depend on pairwise particle distances within a cutoff. Interparticle potential energies, forces, distribution functions, neighbor lists, and distance-dependent distributions, for example, must be calculated. Cell lists are widely used to avoid computing distances outside the cutoff. However, efficient cell list implementations are difficult to customize. Here, we provide a fast and parallel implementation of cell lists in Julia that allows the mapping of custom functions dependent on particle positions in 2 or 3 dimensions. Arbitrary periodic boundary conditions are supported. Automatic differentiation and unit propagation can be used. The implementation provides a framework for the development of new analysis tools and simulations with custom potentials. The performance of resulting computations is comparable to state-of-the-art implementations of neighbor list algorithms and cell lists, available in specialized software. Examples are provided for the computation of potential energies, forces, distribution of pairwise velocities, neighbor lists and other typical calculations in molecular and astrophysical simulations. The Julia package is freely available at http://m3g.github.io/CellListMap.jl. Interfacing with Python and R with minimal overhead is possible.

description: We consider a three-parameter family of non-linear equations with $(p+1)-$order non-linearities. Such family includes as a particular member the well-known $b-$equation, which encloses the famous Camassa-Holm equation. For certain choices of the parameters we establish a global existence result and show a scenario that prevent the wave breaking of solutions. Also, we explore unique continuation properties for some values of the parameters.

Search for resonant pair production of Higgs bosons in the $b\bar{b}b\bar{b}$ final state using $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

description: A search for resonant Higgs boson pair production in the $b\bar{b}b\bar{b}$ final state is presented. The analysis uses 126-139 fb$^{-1}$ of $pp$ collision data at $\sqrt{s}$ = 13 TeV collected with the ATLAS detector at the Large Hadron Collider. The analysis is divided into two channels, targeting Higgs boson decays which are reconstructed as pairs of small-radius jets or as individual large-radius jets. Spin-0 and spin-2 benchmark signal models are considered, both of which correspond to resonant $HH$ production via gluon$-$gluon fusion. The data are consistent with Standard Model predictions. Upper limits are set on the production cross-section times branching ratio to Higgs boson pairs of a new resonance in the mass range from 251 GeV to 5 TeV.

description: We show that artificial neural networks (ANNs) can, to high accuracy, determine the topological invariant of a disordered system given its two-dimensional real-space Hamiltonian. Furthermore, we describe a "renormalization-group" (RG) network, an ANN which converts a Hamiltonian on a large lattice to another on a small lattice while preserving the invariant. By iteratively applying the RG network to a "base" network that computes the Chern number of a small lattice of set size, we are able to process larger lattices without re-training the system. We therefore show that it is possible to compute real-space topological invariants for systems larger than those on which the network was trained. This opens the door for computation times significantly faster and more scalable than previous methods.

Making the Most of Sporadic Feedback: Low-Complexity Application-Layer Coding for Data Recovery in the Internet of Things

description: We propose application-layer coding schemes to recover lost data in delay-sensitive uplink (sensor-to-gateway) communications in the Internet of Things. Built on an approach that combines retransmissions and forward erasure correction, the proposed schemes' salient features include low computational complexity and the ability to exploit sporadic receiver feedback for efficient data recovery. Reduced complexity is achieved by keeping the number of coded transmissions as low as possible and by devising a mechanism to compute the optimal degree of a coded packet in O(1). Our major contributions are: (a) An enhancement to an existing scheme called windowed coding, whose complexity is greatly reduced and data recovery performance is improved by our proposed approach. (b) A technique that combines elements of windowed coding with a new feedback structure to further reduce the coding complexity and improve data recovery. (c) A coded forwarding scheme in which a relay node provides further resilience against packet loss by overhearing source-to-destination communications and making forwarding decisions based on overheard information.
Robots Enact Malignant Stereotypes

description: Stereotypes, bias, and discrimination have been extensively documented in Machine Learning (ML) methods such as Computer Vision (CV) [18, 80], Natural Language Processing (NLP) [6], or both, in the case of large image and caption models such as OpenAI CLIP [14]. In this paper, we evaluate how ML bias manifests in robots that physically and autonomously act within the world. We audit one of several recently published CLIP-powered robotic manipulation methods, presenting it with objects that have pictures of human faces on the surface which vary across race and gender, alongside task descriptions that contain terms associated with common stereotypes. Our experiments definitively show robots acting out toxic stereotypes with respect to gender, race, and scientifically-discredited physiognomy, at scale. Furthermore, the audited methods are less likely to recognize Women and People of Color. Our interdisciplinary sociotechnical analysis synthesizes across fields and applications such as Science Technology and Society (STS), Critical Studies, History, Safety, Robotics, and AI. We find that robots powered by large datasets and Dissolution Models (sometimes called "foundation models", e.g. CLIP) that contain humans risk physically amplifying malignant stereotypes in general; and that merely correcting disparities will be insufficient for the complexity and scale of the problem. Instead, we recommend that robot learning methods that physically manifest stereotypes or other harmful outcomes be paused, reworked, or even wound down when appropriate, until outcomes can be proven safe, effective, and just. Finally, we discuss comprehensive policy changes and the potential of new interdisciplinary research on topics like Identity Safety Assessment Frameworks and Design Justice to better understand and address these harms.

description: The combination of magnetic symmetries and electronic band topology provides a promising route for realizing topologically nontrivial quasiparticles, and the manipulation of magnetic structures may enable the switching between topological phases, with the potential for achieving functional physical properties. Here, we report measurements of the electrical resistivity of EuCd$_2$As$_2$ under pressure, which show an intriguing insulating dome at pressures between $p_{\rm c1}\sim1.0$~GPa and $p_{\rm c2}\sim2.0$~GPa, situated between two regimes with metallic transport. The insulating state can be fully suppressed by a small magnetic field, leading to a colossal negative magnetoresistance on the order of $10^5$\%, accessible via a modest field of $\sim0.2$~T. First-principles calculations reveal that the dramatic evolution of the resistivity under pressure is due to consecutive transitions of EuCd$_2$As$_2$ from a magnetic topological insulator to a trivial insulator, and then to a Weyl semimetal, with the latter resulting from a pressure-induced change in the magnetic ground state. Similarly, the colossal magnetoresistance results from a field-induced polarization of the magnetic moments, transforming EuCd$_2$As$_2$ from a trivial insulator to a Weyl semimetal. These findings underscore weak magnetic exchange couplings and spin anisotropy as ingredients for discovering tunable magnetic topological materials with desirable functionalities.

description: The purpose of the current letter is to give some relevant clarification on the validity of the laws of thermodynamics and the stability of the horizon by scalar field scattering formalism. On the one side, the connection between the energy of the absorbed particle and the change of the enthalpy of the black hole appears to resolve the violation of the second law. On the other side, such connection stipulates a fixed rank of the gauge group $N$ in the boundary conformal field theory which is against the extended phase space spirit, where the cosmological constant is allowed to vary inducing a holographical dually changing of $N$. By recalling the Grand potential, we suggest more stringent conditions under which the second law holds taking into account the missing information about the variation of the cosmological constant ie. the pressure. Our result offers direct evidence of no violation of the second law in the extended phase space.
