description: [transcription] Lyon, 16 septembre 1759.

Monsieur,

J'ai remis à un de nos pères qui part pour Avignon une petite boîte à votre adresse. Je le prie de la donner au Père Paulhan qui est actuellement à Avignon. Celui-ci a pris se retraite, doit aller à Nîmes et sans doute il se fera un plaisir de vous la porter et de vous la présenter. Je voudrais être riche dans cette occasion pour pouvoir vous témoigner ma reconnaissance, mais je suis pauvre et surtout en histoire naturelle, je souhaite que parmi les babioles que je vous envoie, il y ait au moins deux ou trois morceaux que n'ayez point. J'y ai joint quelques médailles entre autres les consulaires que vous souhaitez, quatre monétaire d'Auguste en moyen bronze, un monétaire en grand bronze Marcia, la Legia de M. Antoine XXI mais peut être avec vous tout cela.

[fol. 147 v] Parmi vos médailles doubles ou argent, je n'en trouve aucune que nous n'ayons. Si l'occasion se présente de vous défaire de cette partie, je vous en donnerai avis.

Je dois pendant ces feries revoir notre suite des médailles des villes. Je vous donnerai dans la suite la notice des doubles. Il y a quelques mois de Monsieur le duc de Noia Caraffa passa ici. J'ai de lui plusieurs mémoires et médaillons d'argent des médailles de ville du royaume de Naples : cela a un peu conforté notre suite.

Votre médaillon de Saint-Louis me paraît bien curieuse. Je suis fâché qu'on ait fondu les Louis XI. J'en aurais pris une volontiers. Il me semble de vous avoir écrit que le Père Panel avait fait de toutes ses dissertations un volume in 4°. Ecrivez-lui et il se fera d'en faire présent à un savant comme vous. Votre découverte sur l'inscription de la Maison Carrée vous fait grand honneur. Je crois la chose démontrée.

Je suis avec tout le respect possible.

Monsieur,

Votre très humble et très obéissant serviteur.

Béraud prêtre jésuite

[fol. 148 v][octobre 1759]

description: We quantify the quenching impact of the group environment using the spectroscopic survey Galaxy and Mass Assembly (GAMA) to z=0.2. The fraction of red (quiescent) galaxies, whether in groups or isolated, increases with both stellar mass and large-scale (5 Mpc) density. At fixed stellar mass, the red fraction is on average higher for satellites of red centrals than of blue (star-forming) centrals, a galactic conformity effect that increases with density. Most of the signal originates from groups that have the highest stellar mass, reside in the densest environments, and have massive, red only centrals. Assuming a color-dependent halo-to-stellar-mass ratio, whereby red central galaxies inhabit significantly more massive halos than blue ones of the same stellar mass, two regimes emerge more distinctly: at log(Mhalo/Msol) < 13, central quenching is still ongoing, conformity is no longer existent, and satellites and group centrals exhibit the same quenching excess over field galaxies at all mass and density, in agreement with the concept of "group quenching"; at log(Mhalo/Msol) > 13, a cutoff that sets apart massive (log(M*/Msol) > 11), fully quenched group centrals, conformity is meaningless, and satellites undergo significantly more quenching than their counterparts in smaller halos. The latter effect strongly increases with density, giving rise to the density-dependent conformity signal when both regimes are mixed. The star-formation of blue satellites in massive halos is also suppressed compared to blue field galaxies, while blue group centrals and the majority of blue satellites, which reside in low mass halos, show no deviation from the color-stellar mass relation of blue field galaxies.

description: Para definir los objetivos de política económica del Banco de la República, los delegatarios de la Asamblea Nacional Constituyente de 1991, influidos por los nuevos paradigmas de la política monetaria, trasplantaron el popular modelo de banca central de Objetivo Único alemán. Esperaban que su adopción ayudara al país a alcanzar la estabilidad macroeconómica y, consecuentemente, a garantizar el éxito del proceso de apertura económica iniciado a fina-les de los ochenta. Durante los noventa hubo confusión entre las autoridades sobre cuáles eran realmente los objetivos del banco. Por ello, la Corte Constitucional, a través de la Sentencia C-481 de 1999, intentó aclarar el tema. No obstante, su lectura de la Carta terminó produciendo una mutación constitucional y un nuevo modelo de banca central. A dicho modelo local, más flexible ante escenarios recesivos, como la Crisis de Fin de Siglo o el ocasionado por la pandemia de COVID-19, se le podría denominar banca central de Objetivo Móvil. A partir del análisis de este proceso de trasmutación, este libro estudia, desde una perspectiva económica, histórica y, por supuesto, jurídica, cómo ha evolucionado la política económica constitucional en Colombia.

description: New measurements of the ^12^CO (1-0) and ^12^CO (3-2) line emission are presented for the nuclei of seven nearby starburst galaxies selected from a complete sample of 21 nearby starburst galaxies for which the nuclear star formation rates are measured to be comparable to the archetype starburst galaxies M82 and NGC 253. The new observations capitalize on the coincidence between the beam size of the 45 m Nobeyama telescope at 115 GHz and that of the 15 m James Clerk Maxwell Telescope at 345 GHz to measure the value of the ^12^CO (3-2)/(1-0) emission line ratio in a 15" (<2.5 kpc) diameter region centered on the nuclear starburst. In principle, the ^12^CO (3-2)/(1-0) emission line ratio provides a measure of temperature and optical depth for the ^12^CO gas. The error weighted mean value of the ^12^CO (3-2)/(1-0) emission line ratio measured for the seven starburst galaxy nuclei is 0.64+/-0.06. The ^12^CO (3-2)/(1 -0) emission line ratio measured for the starburst galaxy nuclei is significantly higher than the average value measured for molecular gas in the disk of the Galaxy, implying warmer temperatures for the molecular gas in starburst galaxy nuclei. On the other hand, the ^12^CO (3-2)/(1-0) emission line ratio measured for the starburst galaxy nuclei is not as high as would be expected if the molecular gas were hot, >20 K, and optically thin, τ < 1. The total mass of molecular gas contained within the central 1.2-2.8 kpc diameter region of the starburst galaxy nuclei ranges from 10^8^ to 10^9^ M_sun_. While substantial, the molecular gas mass represents only a small percentage, ~9%-16%, of the dynamical mass in the same region.

description: The False Discovery Rate (FDR) method has recently been described by Miller et al. (2001), along with several examples of astrophysical applications. FDR is a new statistical procedure due to Benjamini & Hochberg (1995) for controlling the fraction of false positives when performing multiple hypothesis testing. The importance of this method to source detection algorithms is immediately clear. To explore the possibilities offered we have developed a new task for performing source detection in radio-telescope images, Sfind 2.0, which implements FDR. We compare Sfind 2.0 with two other source detection and measurement tasks, Imsad and SExtractor, and comment on several issues arising from the nature of the correlation between nearby pixels and the necessary assumption of the null hypothesis. The strong suggestion is made that implementing FDR, as a threshold defining method in other existing source-detection tasks is easy and worhtwhile. We show that the constraint on the fraction of false detections as specified by FDR holds true even for highly correlated and realistic images. For the detection of true sources, which are complex combinations of source-pixels, this constraint appears to be somewhat less strict. It is still reliable enough, however, for a priori estimates of the fraction of false source detections to be robust and realistic. Further investigation of the relationship between `source-pixels' and `sources' is nevertheless important to more strictly constrain the fraction of falsely detected sources.

description: Since only several linear profiles are deployed northward enough to central Qiangtang Terrane, there do not provide good seismic constraints for the northern extent and its lateral variation of the Indian continental lithosphere. It is necessary to deploy a two-dimensional broadband seismic array at central Tibet to illuminate the crust and upper mantle of the plateau and to help us to constrain the geometry of the northern end of the Indian continental lithosphere. The SANDWICH seismic array is a two-dimensional broadband seismic array around the Bangong-Nujiang Suture  in central Tibet installed by the Tectonophysics group of Tethys Research Center at Institute of Geology and Geophysics, Chinese Academy of Sciences (IGGCAS). The SANDWICH array starts from late October 2013 and is expected to finish in November 2016. It consists of 53 broadband seismometers equipped with Guralp CMG-3ESP three-component sensors with a response band from 60/30 second to 50 Hz and Ref Tek 72A-8/130-1 or DAS24-3D 24-bit digital recorders.
Origins of sharp cosmic-ray electron structures and the DAMPE excess

description: Nearby sources may contribute to cosmic-ray electron (CRE) structures at high energies. Recently, the first DAMPE results on the CRE flux hinted at a narrow excess at energy ~1.4 TeV. We show that in general a spectral structure with a narrow width appears in two scenarios: I) "Spectrum broadening" for the continuous sources with a delta-function-like injection spectrum. In this scenario, a finite width can develop after propagation through the Galaxy, which can reveal the distance of the source. Well-motivated sources include mini-spikes and subhalos formed by dark matter (DM) particles $χ_{s}$ which annihilate directly into e+e- pairs. II) "Phase-space shrinking" for burst-like sources with a power-law-like injection spectrum. The spectrum after propagation can shrink at a cooling-related cutoff energy and form a sharp spectral peak. The peak can be more prominent due to the energy-dependent diffusion. In this scenario, the width of the excess constrains both the power index and the distance of the source. Possible such sources are pulsar wind nebulae (PWNe) and supernova remnants (SNRs). We analysis the DAMPE excess and find that the continuous DM sources should be fairly close within ~0.3 kpc, and the annihilation cross sections are close to the thermal value. For the burst-like source, the narrow width of the excess suggests that the injection spectrum must be hard with power index significantly less than two, the distance is within ~(3-4) kpc, and the age of the source is ~0.16 Myr. In both scenarios, large anisotropies in the CRE flux are predicted. We identify possible candidates of mini-spike (PWN) sources in the current Fermi-LAT 3FGL (ATNF) catalog. The diffuse gamma-rays from these sources can be well below the Galactic diffuse gamma-ray backgrounds and less constrained by the Ferm-LAT data, if they are located at the low Galactic latitude regions.

Utilizando un modelo de diferencias en diferencias, se observa una disminución de 3.76e-06 desviaciones estándar en el puntaje global promedio en las instituciones expuestas a la violencia de las FARC-EP. Esta disminución representa un 16.73% del puntaje promedio en el 2014. Al realizar las estimaciones para cada componente de la prueba Saber 11, se obtienen resultados similares. Los hallazgos muestran que el cese al fuego debe estar acompañado de políticas públicas integrales que garanticen las condiciones para el progreso y bienestar de las comunidades educativas de los territorios más afectados por el conflicto armado.
description: This case study estimates the effect of the ceasefire declared by the FARC-EP in 2014 on the performance of educational institutions, measured through the results of the Saber 11 standardized tests. Using a difference-in-differences model, a decrease of 3.87e-06 standard deviations is observed in the average overall score in institutions exposed to FARC-EP violence. This decrease represents 16.73% of the average score in 2014. When estimating for each component of the Saber 11 test, similar results are obtained. The findings show that the ceasefire must be accompanied by comprehensive public policies that guarantee the conditions for the progress and well-being of the educational communities in the territories most affected by the armed conflict.

description: This paper offers new causal evidence on how the timing of prenatal temperature shocks affects fetal health, sex ratio at birth, and early-age human capital. Analyzing data on nearly 2 million live births from sub-Saharan African countries and exploiting exogenous spatial and temporal variation in monthly temperature, we uncover three findings. First, we find that a cold temperature shock decreases the likelihood of a male birth. This effect is non-linear, being larger in the first and third trimesters of pregnancy. It is also highly heterogeneous, being larger for older women, higher parity births, and rural areas. Second, combining our empirical estimates with a climate model, we find that the number of fetal deaths caused by climate change will rise from 200 to 400 per 100,000 live births by 2050 throughout sub-Saharan Africa. Third, in contrast to their differential effect on fetal mortality, prenatal temperature shocks increase infant mortality more for females than for males, suggesting that only healthier male fetuses survive to adverse in utero conditions. Our analysis implies that the design of policies to avert the negative impacts of climate change on children should account for stages of fetal development.

It is found that precisions of +/- 1.68% and +/- 2.97% for pp and Be7 fluxes, respectively, should be achievable in a 5-year data sample. The physics motivation to aim for these precisions is outlined as are the detector design, the methods used in the simulation and sensitivity to solar orbit eccentricity.

description: We propose a Multivariate Gaussian Process Factor Model to estimate low dimensional spatio-temporal patterns of finger motion in repeated reach-to-grasp movements. Our model decomposes and reduces the dimensionality of variation of the multivariate functional data. We first account for time variability through multivariate functional registration, then decompose finger motion into a term that is shared among replications and a term that encodes the variation per replication. We discuss variants of our model, estimation algorithms, and we evaluate its performance in simulations and in data collected from a non-human primate executing a reach-to-grasp task. We show that by taking advantage of the repeated trial structure of the experiments, our model yields an intuitive way to interpret the time and replication variation in our kinematic dataset.

description: Recently there is a lot of attention given to manipulation of heat by constructing thermal devices such as thermal diodes, transistors and logic gates. Many of the models proposed have an asymmetry which leads to the desired effect. Presence of non-linear interactions among the particles is also essential. But, such models lack analytical understanding. Here we propose a simple, analytically solvable model of a thermal diode. Our model consists of classical spins in contact with multiple heat baths and constant external magnetic fields. Interestingly the magnetic field is the only parameter required to get the effect of heat rectification.

"Orphan" afterglows in the Universal Structured Jet Model for gamma-ray bursts

description: The paucity of reliable achromatic breaks in Gamma-Ray Burst afterglow light curves motivates independent measurements of the jet aperture. Serendipitous searches of afterglows, especially at radio wavelengths, have long been the classic alternative. These survey data have been interpreted assuming a uniformly emitting jet with sharp edges (``top-hat'' jet), in which case the ratio of weakly relativistically beamed afterglows to GRBs scales with the jet solid angle. In this paper, we consider, instead, a very wide outflow with a luminosity that decreases across the emitting surface. In particular, we adopt the universal structured jet (USJ) model, that is an alternative to the top-hat model for the structure of the jet. However, the interpretation of the survey data is very different: in the USJ model we only observe the emission within the jet aperture and the observed ratio of prompt emission rate to afterglow rate should solely depend on selection effects. We compute the number and rate of afterglows expected in all-sky snapshot observations as a function of the survey sensitivity. We find that the current (negative) results for OA searches are in agreement with our expectations. In radio and X-ray bands this was mainly due to the low sensitivity of the surveys, while in the optical band the sky-coverage was not sufficient. In general we find that X-ray surveys are poor tools for OA searches, if the jet is structured. On the other hand, the FIRST radio survey and future instruments like the Allen Telescope Array (in the radio band) and especially GAIA, Pan-Starrs and LSST (in the optical band) will have chances to detect afterglows.

A Moment Problem for Order Statistics

description: Necessary and sufficient conditions are given for a triangular array of numbers to be expectations of order statistics of some nonnegative random variable. Using well-known recurrence relations, the expectations of all order statistics of the largest sample size, n, in the triangular array, or the expectations of the smallest of every sample size up to and including n are sufficient to determine the whole array. The former are reduced to a Stieltjes moment problem, the latter to a Hausdorff moment problem. These results are applied to show that for every sample size, there is a positive random variable with geometrically increasing expectations of order statistics with arbitrary ratio and expectation of smallest order statistic. However, only the degenerate distributions have geometrically increasing expectations of order statistics for more than one sample size, even when the ratio and mean of the smallest order statistic can depend on the sample size. These results were required for a study of participation in discussion groups.

reinforced optical table vibration analysis

Publisher: name: International Federation of Digital Seismograph Networks
Year: 2018

description: The MRO Interferometer started in 2017 a seismic measurement campaign to characterize vibration in critical areas where science instruments are to be installed. The following were the goals: to characterize vibrations in the inner BCA at floor level and on the surfaces of two optical tables; and to use these data to see how ground vibrations couple into the inner BCA optical tables. This vibration assessment has indicated that vibration is significantly amplified on the top of optical tables, and that the associated support legs require some level of structural reinforcement. A number of designs have been proposed for revision, and one based on concrete legs was selected for implementation. As a way to reduce implementation risk, the new design with reinforced legs is being implemented in the ineer BCA using one section of the metrology optical table and so a new set of vibration assessment is necessary (expected for March/2018). When the new design is approved for implementation, it will be used in all optical tables installed in the inner BCA during the year of 2018. FREQUENCY RANGE OF INTEREST: We are concerned about vibrations in roughly the 2 Hz - 250 Hz frequency range. It is anticipated that the optical table installed in the inner BCA have a first resonant frequency larger than 40Hz. DIRECTIONS: It is necessary to measure vibrations in all three orthogonal directions (x,y,z). TYPICAL MOTIONS OF INTEREST: We are worried about motions of order 20nm occurring over timescales of order 20ms. Note that 20nm is the sort of OPD difference that matters for interferometry, and 20ms is the near-infrared coherence time. SENSITIVITY REQUIRED: 20nm of motion occuring in 20ms corresponds to a velocity of 1 micron/second. MEASUREMENT CONDITIONS: As performed in previous seismic campaign, it would be good to make recordings with the HVAC running (as it would presumably be during a real observation). Other disturbances, if present, shall be logged. The overall measurement time frame suggested may take no more than a few days.

The main goal is to find reasonable approaches for solutions to problems related to densest sphere packings in 4-dimensional Euclidean space. We consider two long-standing open problems: the uniqueness of maximum kissing arrangements in 4 dimensions and the 24-cell conjecture. Note that a proof of the 24-cell conjecture also proves that the checkerboard lattice packing D4 is the densest sphere packing in 4 dimensions.

description: We propose a new filter, a smooth-$k$ space filter, to use in the Press-Schechter approach to model the dark matter halo mass function which overcomes shortcomings of other filters. We test this against the mass function measured in N-body simulations. We find that the commonly used sharp-$k$ filter fails to reproduce the behaviour of the halo mass function at low masses measured from simulations of models with a sharp truncation in the linear power spectrum. We show that the predictions with our new filter agree with the simulation results over a wider range of halo masses for both damped and undamped power spectra than is the case with the sharp-$k$ and real-space top-hat filters.

Creators: name: James Conder
Publisher: name: International Federation of Digital Seismograph Networks
Year: 2013

description: Flex array deployment in Wabash Valley seismic zone. The Wabash seismic zone is an intraplate seismic zone in the middle of the continent that has received little attention despite several magnitude 4.5-5+ events in the past 50 years. The seismic structure and many basic characteristics remain unknown. The experiment will comprise a line of 45 broad band instruments across the valley and three 9 component short period phased arrays to probe both the physical structure and the levels of background seismicity occurring in this enigmatic feature.

description: We propose a class of graded coronagraphic "amplitude" image masks for a high throughput Lyot-type coronagraph that transmits light from an annular region around an extended source and suppresses light, with extremely high ratio, from elsewhere. The interior radius of the region is comparable with its exterior radius. The masks are designed using an idea inspired by approach due M.J. Kuchner and W.A. Traub ("band-limited" masks) and approach to optimal apodization by D.Slepian. One potential application of our masks is direct high-resolution imaging of exo-planets with the help of the Solar Gravitational Lens, where apparent radius of the "Einstein ring" image of a planet is of the order of an arc-second and is comparable with the apparent radius of the sun and solar corona.

description: The time evolution of the entanglement entropy in non-equilibrium quantum systems provides crucial information about the structure of the time-dependent state. For quantum quench protocols, by combining a quasiparticle picture for the entanglement spreading with the exact knowledge of the stationary state provided by Bethe ansatz, it is possible to obtain an exact and analytic description of the evolution of the entanglement entropy. Here we discuss the application of these ideas to several integrable models. First we show that for non-interacting systems, both bosonic and fermionic, the exact time-dependence of the entanglement entropy can be derived by elementary techniques and without solving the dynamics. We then provide exact results for interacting spin chains that are carefully tested against numerical simulations. Finally, we apply this method to integrable one-dimensional Bose gases (Lieb-Liniger model) both in the attractive and repulsive regimes. We highlight a peculiar behaviour of the entanglement entropy due to the absence of a maximum velocity of excitations.

description: Prediction of purchase timing and quantity decisions of a household is an important element for success of any retailer. This is especially so for an online retailer, as the traditional brick-and-mortar retailer would be more concerned with total sales. A number of statistical models have been developed in the marketing literature to aid traditional retailers in predicting sales and analyzing the impact of various marketing activities on sales. However, there are two important differences between traditional retail outlets and the increasingly important online retail/delivery companies, differences that prevent these firms from using models developed for the traditional retailers: 1) the profits of the online retailer/delivery company depend on purchase frequency and on purchase quantity, while the profits of traditional retailers are simply tied to total sales, and 2) customers in the tails of the frequency distribution are more important to the delivery company than to the retail outlet. Both of these differences are due to the fact that the delivery companies incur a delivery cost for each sale, while customers themselves travel to retail outlets when buying from traditional retailers. These differences in costs translate directly into needs that a model must address. For a model intended to be useful to online retailers the dependent variable should be a bivariate distribution of frequency and quantity, and frequency distribution must accurately represent consumers in the tails. In this article we develop such a model and apply it to predicting the consumer?s joint decision of when to shop and how much to spend at the store. Our approach is to model the marginal distribution of purchase timing and the distribution of purchase quantity conditional on purchase timing. We propose a hierarchical Bayes model that disentangles the weekly and daily components of the purchase timing. The daily component has a dependence on the weekly component thereby accounting for strong observed periodicity in the data. For the purchase times, we use the Conway-Maxwell-Poisson distribution, which we find useful to fit data in the tail regions (extremely frequent and infrequent purchasers).
Edge-induced shear banding in entangled polymeric fluids

description: Despite decades of research, the question of whether solutions and melts of highly entangled polymers exhibit shear banding as their steady state response to a steadily imposed shear flow remains controversial. From a theoretical viewpoint, an important unanswered question is whether the underlying constitutive curve of shear stress $σ$ as a function of shear rate $\dotγ$ (for states of homogeneous shear) is monotonic, or has a region of negative slope, $dσ/d\dotγ<0$, which would trigger banding. Attempts to settle the question experimentally via velocimetry of the flow field inside the fluid are often confounded by an instability of the free surface where the sample meets the outside air, known as "edge fracture". Here we show by numerical simulation that in fact even only very modest edge disturbances - which are the precursor of full edge fracture but might well, in themselves, go unnoticed experimentally - can cause strong secondary flows in the form of shear bands that invade deep into the fluid bulk. Crucially, this is true even when the underlying constitutive curve is monotonically increasing, precluding true bulk shear banding in the absence of edge effects.

description: La minería ha sido, es y será soporte fundamental de la vida humana, de la humanidad y sus civilizaciones. No obstante, en Colombia se encuentra prohibida al interior de los complejos de páramos delimitados considerados ecosistemas estratégicos especialmente por su gran importancia en los procesos de regulación hídrica y su escaza presencia en el mundo. En consecuencia, se sebe ejecutar el programa de Sustitución que involucra el cierre, desmantelamiento, restauración y reconformación de las áreas intervenidas por las actividades mineras en complejos de páramos delimitados, realizando una correcta ponderación del componente socio cultural de las actividades mineras, que garantice los tiempos y medios necesarios para proteger el ecosistema y adaptarse a la nueva situación en condiciones dignas para las comunidades en situación especial de vulnerabilidad y marginalidad en razón de las afectaciones derivadas de las decisiones administrativas.
description: Mining has been, is and will be the fundamental support of human life, humanity and its civilizations. However, in Colombia it is prohibited within the delimited moorland complexes considered strategic ecosystems, especially due to its great importance in water regulation processes and its scarce presence in the world. Consequently, the Substitution program must be executed, which involves the closure, dismantling, restoration and reconformation of the areas intervened by mining activities in delimited moorland complexes, making a correct weighting of the socio-cultural component of mining activities, which guarantees the times and means necessary to protect the ecosystem and adapt to the new situation in decent conditions for communities in a special situation of vulnerability and marginalization due to the effects derived from administrative decisions.

description: L'essor croissant de la Responsabilité Sociale des Entreprises (RSE) au sein des stratégies organisationnelles, en réponse aux défis mondiaux en matière d’attraction et de recrutement de talents, suscite l'intérêt de cette étude qui vise à examiner en profondeur le lien entre la RSE et l'attractivité organisationnelle. À travers une exploration minutieuse de la littérature spécialisée et une analyse approfondie des travaux antérieurs, cette recherche met en lumière la complexité du lien entre la RSE et l'attractivité organisationnelle, révélant des ambiguïtés et des divergences significatives dans la littérature. Ces divergences s'articulent autour de la reconnaissance ou du rejet d'un lien direct entre la RSE et l'attractivité organisationnelle et s'ouvrent sur une troisième perspective conditionnant l'existence de ce lien à la présence de variables médiatrices et modératrices. En s'appuyant sur ces conclusions, cette étude propose un modèle consolidé résumant les divergences issues de la revue de littérature, visant à fournir une perspective complète et éclairée sur la complexité du lien entre la RSE et l'attractivité organisationnelle, apportant ainsi une contribution substantielle à la compréhension approfondie de cette dynamique cruciale.

description: Achieving large-area uniform two-dimensional (2D) metal-organic frameworks (MOFs) and controlling their electronic properties on inert surfaces is a big step towards future applications in electronic devices. Here we successfully fabricated a 2D monolayer Cu-dicyanoanthracene (DCA) MOF with long-range order on an epitaxial graphene surface. Its structural and electronic properties are studied by low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS) complemented by density-functional theory (DFT) calculations. We demonstrate access to multiple molecular charge states in the 2D MOF using tip-induced local electric fields. We expect that a similar strategy could be applied to fabricate and characterize 2D MOFs with exotic, engineered electronic states.
