Determining usefulness of machine learning in materials discovery using simulated research landscapes.

Phys Chem Chem Phys 2021 Jul;23(26):14156-14163

Department of Chemistry, University of Liverpool, Liverpool, L69 3BX, UK.

When existing experimental data are combined with machine learning (ML) to predict the performance of new materials, the data acquisition bias determines ML usefulness and the prediction accuracy. In this context, the following two conditions are highly common: (i) constructing new unbiased data sets is too expensive and the global knowledge effectively does not change by performing a limited number of novel measurements; (ii) the performance of the material depends on a limited number of physical parameters, much smaller than the range of variables that can be changed, albeit such parameters are unknown or not measurable. To determine the usefulness of ML under these conditions, we introduce the concept of simulated research landscapes, which describe how datasets of arbitrary complexity evolve over time. Simulated research landscapes allow us to use different discovery strategies to compare standard materials exploration with ML-guided explorations, i.e. we can measure quantitatively the benefit of using a specific ML model. We show that there is a window of opportunity to obtain a significant benefit from ML-guided strategies. The adoption of ML can take place too soon (not enough information to find patterns) or too late (dense datasets only allow for negligible ML benefit), and the adoption of ML can even slow down the discovery process in some cases. We offer a qualitative guide on when ML can accelerate the discovery of new best-performing materials in a field under specific conditions. The answer in each case depends on factors like data dimensionality, corrugation and data collection strategy. We consider how these factors may affect the ML prediction capabilities and discuss some general trends.

Backlash in global health and the end of AIDS' exceptionalism in Brazil, 2007-2019.

Glob Public Health 2021 Mar 9:1-12. Epub 2021 Mar 9.

Casa de Oswaldo Cruz, Fiocruz, Rio de Janeiro, Brazil.

This paper examines the decline of the AIDS Programme in Brazil, the Latin American country most affected by the epidemic, with emphasis in the second decade of the twenty-first century. For many years, Brazil served as a model in Global Health due to a comprehensive preventive policy, a partnership between the government and health activists and the support of life-saving drugs as public goods rather than commodities. The regression of AIDS policies in Brazil interacted with developments in the United States as well as with multilateral agencies like UNAIDS that emphasised biomedicalisation in the response to the disease where broad human-rights programmes and alliance with activists were not priorities. International programmes like the 'Ending AIDS' campaign indirectly undermined the exceptional status AIDS enjoyed since the late 1980s. The backlash in Brazilian policies to fight AIDS was a result of the fragmentation of the left and the empowerment of radical conservative authoritarian and religious forces. The result was the breakdown of the long-held belief that successful anti-AIDS disease programmes could simultaneously help control the disease and build better healthcare systems and ultimately prompted the end of the special place AIDS' policy had in Brazil.

Prominent out-of-plane diffraction in helium scattering from a methyl-terminated Si(111) surface.

Phys Chem Chem Phys 2019 Jul;21(28):15879-15887

Departamento de Química Módulo 13, Universidad Autónoma de Madrid, 28049 Madrid, Spain. and Condensed Matter Physics Center (IFIMAC), Universidad Autónoma de Madrid, 28049 Madrid, Spain and Institute for Advanced Research in Chemistry (IAdChem), Universidad Autónoma de Madrid, 28049 Madrid, Spain.

Due to their electrochemical and oxidative stability, organic-terminated semiconductor surfaces are well suited to applications in, for example, photoelectrodes and electrochemical cells, which explains the lively interest in their detailed characterization. Helium atom scattering (HAS) is a useful tool to carry out such characterization. Here, we have simulated HAS in He/CH3-Si(111) based on density functional theory (DFT) potential energy surfaces (PESs) and multi-configuration time-dependent Hartree (MCTDH) dynamics. Our analysis of HAS shows that most diffraction taking place in this system corresponds to high-order out-of-plane peaks. This is a general trend that does not depend on the specific features of the simulations, such as the inclusion or not of the van der Waals long-range effects. This is the first and only He-surface system for which such huge out-of-plane diffraction has been described. This striking theoretical finding should encourage new experimental developments to confirm this previously unreported effect.

Performance of van der Waals DFT approaches for helium diffraction on metal surfaces.

J Phys Condens Matter 2019 Apr 9;31(13):135901. Epub 2019 Jan 9.

Departamento de Química Módulo 13, Universidad Autónoma de Madrid, 28049 Madrid, Spain.

The ability of the different approaches proposed to date to include the effects of van der Waals (vdW) dispersion forces in density functional theory (DFT) is currently under debate. Here, we used the diffraction of He on a Ru(0 0 0 1) surface as a challenging benchmark system to analyze the suitability of several representative approaches, from the ones correcting the exchange-correlation generalized gradient approximation (GGA) functional, to the ones correcting the DFT energies through pairwise-based methods. To perform our analysis, we have built seven continuous potential energy surfaces (PESs) and carried out quantum dynamics simulations using a multi-configuration time-dependent Hartree method. Our analysis reveals that standard DFT within the PBE-GGA framework, although it overestimates diffraction probabilities, yields the best results in comparison with available experimental measurements. On the other hand, although several of the existing vdW DFT approaches yield physisorption wells in very good agreement with experiment, they all seem to overestimate the long-distance corrugation of the PES, the region probed by He scattering, resulting in a large overestimation of diffraction probabilities.

Zika and Aedes aegypti: new and old challenges.

Hist Cienc Saude Manguinhos 2017 Oct-Dec;24(4):1161-1180

Pesquisador, COC/Fiocruz.

Infection with the zika virus had a great impact not only on pregnant women and newborns, but also on public health, on popular ideas about Aedes aegypti and with respect to women's social rights. The objective of this paper is to identify this impact and the historical, social and health changes of the disease and the legacy of the zika virus. Interventions by researchers from different specialties foster conditions for more comprehensive investigations into future epidemic threats in Brazil and Latin America. This dialogue took place after the seminar "Aedes aegypti: past and future health emergencies," organized by the Casa de Oswaldo Cruz, when we talked with some speakers and other leading researchers about the history and challenges of Aedes aegypti and zika.

The Alma-Ata Decade: the crisis of development and international health.

Cien Saude Colet 2017 Jul;22(7):2135-2144

Departamento de Pesquisa em História das Ciências e da Saúde. Casa de Oswaldo Cruz, Fiocruz. Av. Brasil 4036/405, Manguinhos. 21040-361 Rio de Janeiro RJ Brasil.

The paper analyzes formulations in the area of international health at the time of the International Conference on Primary Health Care, held in Alma Ata, Kazakhstan, in 1978. It is set within the context of the broader debate on development and international cooperation throughout the 1970s. Three sets of concepts and prescriptive formulations were examined namely: the New International Economic Order (NIEO), the Dag Hammarskjöld Report (DHR) and the Basic Human Needs Approach (BHN). They were compared with the proposals in documents from the World Health Organization and in the statements from Halfdan Mahler, its director. As a whole, this set of formulations and proposals share a broad spectrum of terms and notions, as well as much of the expectations for change and tensions that existed in the classic period of development during the later years of the post-war era.

At the Roots of The World Health Organization's Challenges: Politics and Regionalization.

Am J Public Health 2016 11;106(11):1912-1917

The World Health Organization's (WHO's) leadership challenges can be traced to its first decades of existence. Central to its governance and practice is regionalization: the division of its member countries into regions, each representing 1 geographical or cultural area. The particular composition of each region has varied over time-reflecting political divisions and especially decolonization. Currently, the 194 member countries belong to 6 regions: the Americas (35 countries), Europe (53 countries), the Eastern Mediterranean (21 countries), South-East Asia (11 countries), the Western Pacific (27 countries), and Africa (47 countries). The regions have considerable autonomy with their own leadership, budget, and priorities. This regional organization has been controversial since its beginnings in the first days of WHO, when representatives of the European countries believed that each country should have a direct relationship with the headquarters in Geneva, Switzerland, whereas others (especially the United States) argued in favor of the regionalization plan. Over time, regional directors have inevitably challenged the WHO directors-general over their degree of autonomy, responsibilities and duties, budgets, and national composition; similar tensions have occurred within regions. This article traces the historical roots of these challenges.

Experimental and theoretical study of rotationally inelastic diffraction of H2(D2) from methyl-terminated Si(111).

J Chem Phys 2016 Aug;145(8):084705

The James Franck Institute and Department of Chemistry, The University of Chicago, 929 E. 57th Street, Chicago, Illinois 60637, USA.

Fundamental details concerning the interaction between H2 and CH3-Si(111) have been elucidated by the combination of diffractive scattering experiments and electronic structure and scattering calculations. Rotationally inelastic diffraction (RID) of H2 and D2 from this model hydrocarbon-decorated semiconductor interface has been confirmed for the first time via both time-of-flight and diffraction measurements, with modest j = 0 → 2 RID intensities for H2 compared to the strong RID features observed for D2 over a large range of kinematic scattering conditions along two high-symmetry azimuthal directions. The Debye-Waller model was applied to the thermal attenuation of diffraction peaks, allowing for precise determination of the RID probabilities by accounting for incoherent motion of the CH3-Si(111) surface atoms. The probabilities of rotationally inelastic diffraction of H2 and D2 have been quantitatively evaluated as a function of beam energy and scattering angle, and have been compared with complementary electronic structure and scattering calculations to provide insight into the interaction potential between H2 (D2) and hence the surface charge density distribution. Specifically, a six-dimensional potential energy surface (PES), describing the electronic structure of the H2(D2)/CH3-Si(111) system, has been computed based on interpolation of density functional theory energies. Quantum and classical dynamics simulations have allowed for an assessment of the accuracy of the PES, and subsequently for identification of the features of the PES that serve as classical turning points. A close scrutiny of the PES reveals the highly anisotropic character of the interaction potential at these turning points. This combination of experiment and theory provides new and important details about the interaction of H2 with a hybrid organic-semiconductor interface, which can be used to further investigate energy flow in technologically relevant systems.
