description: This report describes take-up and adoption of work produced by RDA and, more specifically, the role of the RDA Europe 4.0 project in promoting such take-up and adoption. It is the second of two reports which will cover this topic; the first version, D2.1 RDA Results, Adoption and take-up report, was delivered in May 2019. The Research Data Alliance has 43 Recommendations and Supporting Outputs, 8 of which are officially acknowledged as ICT Technical Specifications. There are also several more Recommendations and Supporting Outputs in the process of endorsement. A full list can be seen on the RDA website using the RDA’s new Recommendations and Outputs catalogue tool.1.
 A number of actions have been taken by the RDA Europe project to increase the adoption of outputs, including: A successful open call to award grants to adoption projects; Increasing the volume of published Adoption Stories online, including the introduction of new audiovisual Adoption Stories; Facilitating the publication of articles in the CODATA Data Science Journal Special Collection on RDA Results; Promoting and disseminating RDA use cases by illustrating examples in webinars, plenary sessions, and in the RDA Global Adoption Week in June 2020. In addition, cascading grants directed toward RDA Europe Ambassadors for disciplines and in the establishment of RDA National Nodes have played a role in fostering the take-up of RDA results. The RDA Secretariat also convened a Global Adoption Task Force during the RDA Europe 4.0 project period, which has worked with organisations who have implemented RDA Outputs in order to produce use cases for supporting adoption and has actively tracked the uptake of outputs throughout the duration of the RDA Europe 4.0 project.

description: Using a Monte Carlo method, we have directly extracted from the available measurements, the hierarchies among the different elements of the quark mass matrices. To do that, we have first introduced a model independent parameterization for two generic class of models: those based on Abelian symmetries and those inspired by a U(2) horizontal symmetry. So, matrix entries are proportional to some epsilon^t, with epsilon<<1 and the t's are different free exponents that we determine from the data through a statistically well defined procedure. We have found that the experimental data poorly constrain the Abelian scenarios. Instead, in non Abelian scenarios, these t-exponents are strongly constrained by the present data. We have found that contrary to a naive U(2) horizontal symmetry expectation, quark mass matrices turn out to be not symmetric. Two solutions emerge: one with M_{32}^{down}>> M_{23}^{down}} and M_{21}^{up}>> M_{12}^{up}; and a second one with slight asymmetries only in the light quark sector, namely M_{21}^{up} < M_{12}^{up} and M_{21}^{down}>M_{12}^{down}.

description: This paper identifies and estimates the effects of several determinants on private investment in irrigation in Colombia. It attempts to quantify macroeconomic policy, environment, and violence variables that have been identified in previous studies as significantly affecting investment in agriculture in general, and in irrigation in particular. Variables such as violence, climate, and governmental price and credit policies are used to explain changes in private investment in irrigation across regions and over time. Violence negatively affects private investment. Climate affects the investment such that in regions with favorable climate conditions, investment in irrigation is less attractive, and appropriate government crop-price and credit policies promote investment in irrigation.

Kinetic Equations for Diffusion in the Presence of Entropic Barriers

description: We use the mesoscopic nonequilibrium thermodynamics theory to derive the general kinetic equation of a system in the presence of potential barriers. The result is applied to the description of the evolution of systems whose dynamics is influenced by entropic barriers. We analyze in detail the case of diffusion in a domain of irregular geometry in which the presence of the boundaries induces an entropy barrier when approaching the exact dynamics by a coarsening of the description. The corresponding kinetic equation, named Fick-Jacobs equation, is obtained, and its validity is generalized through the formulation of a scaling law for the diffusion coefficient which depends on the shape of the boundaries. The method we propose can be useful to analyze the dynamics of systems at the nanoscale where the presence of entropy barriers is a common feature.

He II Emission from Wolf-Rayet Stars as a Tool for Measuring Dust Reddening

description: We calibrated a technique to measure dust attenuation in star-forming galaxies. The technique utilizes the stellar-wind lines in Wolf-Rayet stars, which are widely observed in galaxy spectra. The He II 1640 and 4686 features are recombination lines whose ratio is largely determined by atomic physics. Therefore they can serve as a stellar dust probe in the same way as the Balmer lines are used as a nebular probe. We measured the strength of the He II 1640 line in 97 Wolf-Rayet stars in the Galaxy and the Large Magellanic Cloud. The reddening corrected fluxes follow a tight correlation with a fixed ratio of 7.76 for the He II 1640 to 4686 line ratio. Dust attenuation decreases this ratio. We provide a relation between the stellar E(B-V) and the observed line ratio for several attenuation laws. Combining this technique with the use of the nebular Balmer decrement allows the determination of the stellar and nebular dust attenuation in galaxies and can probe its effects at different stellar age and mass regimes, independently of the initial mass function and the star-formation history. We derived the dust reddening from the He II line fluxes and compared it to the reddening from the Balmer decrement and from the slope of the ultraviolet continuum in two star-forming galaxies. The three methods result in dust attenuations which agree to within the errors. Future application of this technique permits studies of the stellar dust attenuation compared to the nebular attenuation in a representative galaxy sample.

Boltzmann-type description with cutoff of Follow-the-Leader traffic models

description: In this paper we consider a Boltzmann-type kinetic description of Follow-the-Leader traffic dynamics and we study the resulting asymptotic distributions, namely the counterpart of the Maxwellian distribution of the classical kinetic theory. In the Boltzmann-type equation we include a non-constant collision kernel, in the form of a cutoff, in order to exclude from the statistical model possibly unphysical interactions. In spite of the increased analytical difficulty caused by this further non-linearity, we show that a careful application of the quasi-invariant limit (an asymptotic procedure reminiscent of the grazing collision limit) successfully leads to a Fokker-Planck approximation of the original Boltzmann-type equation, whence stationary distributions can be explicitly computed. Our analytical results justify, from a genuinely model-based point of view, some empirical results found in the literature by interpolation of experimental data.

description: We investigate the seemingly ill-defined problem of extracting a ground-state mass from a lattice simulation where the extent of the lattice is not long enough to project out the ground-state properly. We regulate the problem using a Bayesian method. We show that controlling meta-parameters (overconfidence) can allow the data to overcome the input priors (bias). We can write the method as a black-box technique which allows extraction of a ground-state mass, even on a relatively short lattice.

description: The transition of QGP from fluid-dynamical regime to freeze-out is accompanied by the onset of instabilities. In the present paper we investigate the impact of the magnetic field on the Rayleigh instability. We show that extremely strong field generated in peripheral heavy ion collisions has an insignificant influence on the Rayleigh bubble dynamics. Magnetic "friction" turns out to be much weaker than the viscous one.

description: We numerically investigate the formation of D-dimensional black holes in high-energy particle collision with the impact parameter and evaluate the total cross section of the black hole production. We find that the formation of an apparent horizon occurs when the distance between the colliding particles is less than 1.5 times the effective gravitational radius of each particles. Our numerical result indicates that although both the one-dimensional hoop and the (D-3)-dimensional volume corresponding to the typical scale of the system give a fairly good condition for the horizon formation in the higher-dimensional gravity, the (D-3)-dimensional volume provide a better condition to judge the existence of the horizon.

description: This paper reviews the literature dealing with the link of agricultural prices and macroeconomic policies to agiicultural supply with particular emphasis on Sub-Saharan Africa. Although the study echoes the stylized facts on price elasticities underlined in previous literature reviews, the paper points out that our understanding of the quantitative dimensions of agricultural supply response is weak given the importance of this assumed response for growth, poverty alleviation, and the environment Indeed, issues such as simultaneity of variables, data pooling, omission of variables, and asymmetry in supply responses to price changes have not been adequately addressed in many instances. © 1997 Elsevier Science B.V.

description: We summarize the different puzzles raised by aging experiments of spin-glasses and their various interpretations. We try to reconcile the `real space', droplet like pictures with the hierarchical pictures that have been proposed in the past. The basic ingredient is a strong separation of the time scales that govern the dynamics of the system on different length scales. Changing the temperature changes the length scale at which the system is observed, thereby allowing rejuvenation (that concerns short length scales) and memory (stored in long length scales) to coexist. We show that previous experiments can be reanalyzed in terms of {\it vanishing energy barriers} at the spin-glass transition, an important ingredient to obtain a fast separation of time scales. We propose to distinguish between `fixed landscape rejuvenation', which is already present in simple two (or multi) level systems, from the `strong' chaos effect on scales larger than an `overlap length' conjectured in the context of the droplet model. We argue that most experiments can be accounted for without invoking the existence of an overlap length. New experiments are presented to test some recent predictions of the strong chaos scenario, with negative results.

description: Gauge theories with gauge group $SU(N)$ and quarks belonging to arbitrary representations of $SU(N)$ form a rich landscape of QCD-like theories, whose study can shed new light on the properties of confinement. Four cases are particularly worth of interest: quarks in the fundamental representation, quarks in the 2-indice (anti)symmetric representation and quarks in the adjoint representation. The last three corresponding QCD-like theories are equivalent at large-$N$ for bosonic observables: It is the orientifold equivalence. The behavior of the lightest vector meson mass versus $N$ has been studied in quenched lattice QCD in the chiral limit in these theories. We show that the observed behaviors are compatible with a string tension proportional to the quadratic Casimir of $SU(N)$ in the quark color representation, $\textit{i.e.}$ with the Casimir scaling hypothesis. The large-$N$ limit of some excited meson masses computed in quenched lattice QCD with quarks in the fundamental representation is also shown to be compatible with QCD string's well-known signature: Regge trajectories.

Productivity Analysis

description: The cultivation of wheat in Saudi Arabia has been claimed to be resource depletable. Huge amounts of high quality inputs, especially water, seeds, and nitrogen fertilizers, have been applied to the sandy Saudi soils to increase productivity. However, the economic feasibility of wheat production has been totally neglected, mainly for political reasons. Classical production functions analysis has not yielded significant conclusions regarding the use of inputs. A 3-year experiment on an educational farm with a soil type representative of the agricultural soil in Saudi Arabia, yielded some interesting results concerning the use of inputs. The findings were obtained through the stochastic dominance efficiency criterion which assessed the efficient levels of seeds, water, and nitrogen fertilizers in wheat cultivation when production risk was considered.

description: A model of a mixture of spinless fermions and spin-zero hardcore bosons, with filling fractions $ρ_F$ and $ρ_B$, respectively, on a two-dimensional square lattice with {\em composite} hopping $t$ is presented. In this model, hopping swaps the locations of a fermion and a boson at nearest-neighbor sites. When $ρ_F+ρ_B=1$, the fermion hopping amplitude $ϕ$ and boson superfluid amplitude $ψ$ are calculated in the ground state within a mean-field approximation. The Fermi sector is insulating ($ϕ=0$) and the Bose sector is normal ($ψ=0$) for $0 \le ρ_F < ρ_c$. The model has {\em coupled first-order} transitions at $ρ_F = ρ_c \simeq 0.3$ where both $ϕ$ and $ψ$ are discontinuous. The Fermi sector is metallic ($ϕ>0$) and the Bose sector is superfluid ($ψ>0$) for $ρ_c < ρ_F < 1$. At $ρ_F=1/2$, fermion density of states $ρ$ has a van Hove singularity, the bulk modulus $κ$ displays a cusp-like singularity, the system has a density wave (DW) order, and $ϕ$ and $ψ$ are maximum. At $ρ_F=ρ_κ \simeq 0.81$, $κ$ vanishes, becoming {\em negative} for $ρ_κ

Doubly heavy exotic resonances X and Z can be described as color molecules of two-quark lumps, the analogue of the H_2 molecule, and doubly heavy baryons as the analog of the H_2^+ ion, except that the two heavy quarks attract each other. We compare our results with constituent quark model and lattice QCD calculations and find further evidence in support of this upgraded picture of compact tetraquarks and baryons.

The strip runs parallel to the edge of a gate deposited on the sample and forms at positions where an exact number of integer Landau levels is filled. An RC model of charging fits the data well and enables us to determine the longitudinal resistance of the strip. Surprisingly, we find that the strip becomes more resistive as its width decreases.

description: The on-chip creation of coherent light at visible wavelengths is crucial to field-level deployment of spectroscopy and metrology systems. Although on-chip lasers have been implemented in specific cases, a general solution that is not restricted by limitations of specific gain media has not been reported. Here, we propose creating visible light from an infrared pump by widely-separated optical parametric oscillation (OPO) using silicon nanophotonics. The OPO creates signal and idler light in the 700 nm and 1300 nm bands, respectively, with a 900 nm pump. It operates at a threshold power of (0.9 +/- 0.1) mW, over 50x smaller than other widely-separated microcavity OPO works, which have only been reported in the infrared. This low threshold enables direct pumping without need of an intermediate optical amplifier. We further show how the device design can be modified to generate 780 nm and 1500 nm light with a similar power efficiency. Our nanophotonic OPO shows distinct advantages in power efficiency, operation stability, and device scalability, and is a major advance towards flexible on-chip generation of coherent visible light.
Decoherence and bare mass induced by nonconformal metric fluctuations

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The effects, upon the Klein--Gordon field, of nonconformal stochastic metric fluctuations, are analyzed. It will be shown that these fluctuations allow us to consider an effective mass, i.e., the mass detected in a laboratory is not the parameter appearing in the Klein--Gordon equation, but a function of this parameter and of the fluctuations of the metric. In other words, in analogy to the case of a nonrelativistic electron in interaction with a quantized electromagnetic field, we may speak of a bare mass, where the observed mass shows a dependence upon the stochastic terms included in the metric. Afterwards, we prove, resorting to the influence functional, that the energy--momentum tensor of the Klein--Gordon field inherites this stochastic behavior, and that this feature provokes decoherence upon a particle immersed in the region where this tensor is present.

description: A series of new hydrazones bearing pyridyl and thiazolyl scaffolds have been synthesized and evaluated for their in vitro anticancer and antimicrobial activities. The anticancer activity was evaluated against the A549 lung cancer cell line. The eight hydrazone derivatives have shown better anticancer activity than positive control doxorubicin against the A549 lung cancer cell line. The antimicrobial activity was evaluated against bacterial and fungal pathogens by using well diffusion method. The four hydrazone derivatives have displayed good antimicrobial activities. Molecular docking studies of the synthesized hydrazone derivatives revealed good binding via hydrogen bond interactions with key residues on active sites as well as neighboring residues with an active site of Focal adhesion kinase (PDB ID 2JKO). A computational study for the prediction of absorption, distribution, metabolism, and excretion (ADME) properties of all compounds has also been performed.

description: We study the event-by-event fluctuations of the charged particles and compare the results of different Monte-Carlo Generators (MCG): VNIb, HIJING, HIJING/B${\bar B}$ and RQMD. We find that the $D$-measure can be used to distinguish between the different gluon populations that are present in the MCG models. On the other hand, the value of the $D$-measure shows high sensitivity to the rescattering effects in VNIb model, but lower sensitivity to the rescattering effects in RQMD model. We also find that the $D$-measures from AA are consistent with the $D$-measures from $pp$ for all generators except VNIb. Therefore, any deviation among the values of $D$-measure for different impact parameters and between $pp$ and $AA$ collisions may indicate that either the rescattering effects play a key role in the interactions or there is new physics in $AA$ collisions.

description: Black student retention, persistence, and graduation rates nationally have continued to lag behind other ethnic groups. Data show Black students have lower completion rates than Latinx, White, and Asian students. Academic advising is an important relationship that can help close the student success gap through structured and intentional proactive advising approaches. The purpose of this qualitative phenomenological study was to examine students’ understanding and perceptions of—and experiences with—engagement in a proactive advising approach and the resulting impact on the Black student experience in higher education. Two research questions served as the foundational components in exploring Black students experience in a proactive advising approach: 1. What are the experiences of Black students in a proactive advising approach? 2. How do Black students perceive proactive advising experiences and their impact on persistence? To achieve the study purpose, four focus groups were conducted with a total of 21 Black students from two institutions. The findings indicated proactive advising is effective when it involves personalized outreach that expresses individualized consideration and care; same-race advisors are perceived as more effective at providing individualized consideration, care, and sense of belonging; and proactive advising that involves individualized consideration and care positively impacts persistence.
Three-loop contribution of the Faddeev-Popov ghosts to the $β$-function of ${\cal N}=1$ supersymmetric gauge theories and the NSVZ relation

description: We find the three-loop contribution to the $β$-function of ${\cal N}=1$ supersymmetric gauge theories regularized by higher covariant derivatives produced by the supergraphs containing loops of the Faddeev--Popov ghosts. This is done using a recently proposed algorithm, which essentially simplifies such multiloop calculations. The result is presented in the form of an integral of double total derivatives in the momentum space. The considered contribution to the $β$-function is compared with the two-loop anomalous dimension of the Faddeev--Popov ghosts. This allows verifying the validity of the NSVZ equation written as a relation between the $β$-function and the anomalous dimensions of the quantum superfields. It is demonstrated that in the considered approximation the NSVZ equation is satisfied for the renormalization group functions defined in terms of the bare couplings. The necessity of the nonlinear renormalization for the quantum gauge superfield is also confirmed.

description: Achieving end-to-end ultra-reliability and resiliency in mission critical communications is a major challenge for future wireless networks. Dual connectivity has been proposed by 3GPP as one of the viable solutions to fulfill the reliability requirements. However, the potential correlation in failures occurring over different wireless links is commonly neglected in current network design approaches. In this paper, we investigate the impact of realistic correlation among different wireless links on end-to-end reliability for two selected architectures from 3GPP. In ultra-reliable use-cases, we show that even small values of correlation can increase the end-to-end error rate by orders of magnitude. This may suggest alternative feasible architecture designs and paves the way towards serving ultra-reliable communications in 5G networks.

A Neutral Beam Model for High-Energy Neutrino Emission from the Blazar TXS 0506+056

description: The IceCube collaboration reported a $\sim 3.5σ$ excess of $13\pm5$ neutrino events in the direction of the blazar TXS 0506+56 during a $\sim$6 month period in 2014-2015, as well as the ($\sim3σ$) detection of a high-energy muon neutrino during an electromagnetic flare in 2017. We explore the possibility that the 2014-2015 neutrino excess and the 2017 multi-messenger flare are both explained in a common physical framework that relies on the emergence of a relativistic neutral beam in the blazar jet due to interactions of accelerated cosmic rays (CRs) with photons. We demonstrate that the neutral beam model provides an explanation for the 2014-2015 neutrino excess without violating X-ray and $γ$-ray constraints, and also yields results consistent with the detection of one high-energy neutrino during the 2017 flare. If both neutrino associations with TXS 05065+056 are real, our model requires that (i) the composition of accelerated CRs is light, with a ratio of helium nuclei to protons $\gtrsim5$, (ii) a luminous external photon field ($\sim 10^{46}$ erg s$^{-1}$) variable (on year-long timescales) is present, and (iii) the CR injection luminosity as well as the properties of the dissipation region (i.e., Lorentz factor, magnetic field, and size) vary on year-long timescales.

description: Recently a new class of theories of electroweak symmetry breaking have been constructed. These models, based on deconstruction and the physics of theory space, provide the first alternative to weak-scale supersymmetry with naturally light Higgs fields and perturbative new physics at the TeV scale. The Higgs is light because it is a pseudo-Goldstone boson, and the quadratically divergent contributions to the Higgs mass are cancelled by new TeV scale ``partners'' of the {\em same} statistics. In this paper we present the minimal theory space model of electroweak symmetry breaking, with two sites and four link fields, and the minimal set of fermions. There are very few parameters and degrees of freedom beyond the Standard Model. Below a TeV, we have the Standard Model with two light Higgs doublets, and an additional complex scalar weak triplet and singlet. At the TeV scale, the new particles that cancel the 1-loop quadratic divergences in the Higgs mass are revealed. The entire Higgs potential needed for electroweak symmetry breaking--the quartic couplings as well as the familiar negative mass squared--can be generated by the top Yukawa coupling, providing a novel link between the physics of flavor and electroweak symmetry breaking.
description: 15 pages. References added. Included clarifying comments on the origin of quartic couplings, and on power-counting. More elegant model for generating Higgs potential from top Yukawa coupling presented

description: Spatial dependence of the magnetic field and the superconducting current in a flux line pinned by a screw dislocation are computed. Interaction of a superconducting vortex with the chiral-symmetry breaking elastic strain of a screw dislocation results in a helical current along the axis of the dislocation. It is argued that screw dislocations make impossible a force-free arrangement of flux lines in the presence of a transport current.
