A movie and still images of a nucleation event at the NP with Eads=∆Hvap ≈ 0:9 are also provided. a)Electronic mail: [email protected] 1 I. FURTHER SIMULATIONS DETAILS To construct the NP, the ASE package1 was used: 6 atomic layers were used in the f1,0,0g family of directions; 9 layers in the f1,1,0g family; and 5 layers in the f1,1,1g family, except along the (1¯; 1¯; 1)¯ direction where no layers were used. As the equations of motion for the atoms in the NP were not integrated (i.e. they were fixed) no interaction potential was defined between them, and the adsorption energy Eads of a water monomer to the NP was therefore simply defined as the total energy after geometry optimization of a single water molecule at the center of the (111) face. The velocity Verlet algorithm was used to propagate the equations of motion of the water molecules, using a 10 fs time step. -
Biology Powerhouse Raises Railway Alarm
NEWS IN FOCUS to enrol all participants by 2018. Certain factors make researchers optimis- tic that the British study will succeed where the US one failed. One is the National Health Service, which provides care for almost all pregnant women and their children in the United Kingdom, and so offers a centralized means of recruiting, tracing and collecting medical information on study participants. In the United States, by contrast, medical care is provided by a patchwork of differ- ent providers. “I think that most researchers in the US recognize that our way of doing population-based research here is simply different from the way things can be done in the UK and in Europe, and it will almost always be more expensive here,” says Mark Klebanoff, a paediatric epidemiologist at Nationwide Children’s Hospital in Colum- bus, Ohio, who was involved in early dis- cussions about the US study. The Francis Crick Institute sits at the nexus of three central London railway hubs. At one stage, US researchers had planned to knock on doors of random houses looking URBAN SCIENCE for women to enrol before they were even pregnant. “It became obvious that that wasn’t going to be a winning formula,” says Philip Pizzo, a paediatrician at Stanford University Biology powerhouse in Palo Alto, California, who co-chaired the working group that concluded that the National Children’s Study was not feasible. raises railway alarm “The very notion that someone was going to show up on your doorstep as a representa- tive from a government-funded study and Central London’s Francis Crick Institute fears that proposed say ‘Are you thinking of getting pregnant?’ train line will disrupt delicate science experiments. -

Generalised Noncommutative Geometry on Finite Groups and Hopf
J. Noncommut. Geom. 13 (2019), 1055–1116 Journal of Noncommutative Geometry DOI 10.4171/JNCG/345 © European Mathematical Society Generalised noncommutative geometry on finite groups and Hopf quivers Shahn Majid and Wen-Qing Tao Abstract. We explore the differential geometry of finite sets where the differential structure is given by a quiver rather than as more usual by a graph. In the finite group case we show that the data for such a differential calculus is described by certain Hopf quiver data as familiar in the context of path algebras. We explore a duality between geometry on the function algebra vs geometry on the group algebra, i.e. on the dual Hopf algebra, illustrated by the noncommutative Riemannian geometry of the group algebra of S3. We show how quiver geometries arise naturally in the context of quantum principal bundles. We provide a formulation of bimodule Riemannian geometry for quantum metrics on a quiver, with a fully worked example on 2 points; in the quiver case, metric data assigns matrices not real numbers to the edges of a graph. The paper builds on the general theory in our previous work [19]. Mathematics Subject Classification (2010). 81R50, 58B32, 16G20. Keywords. Hopf algebra, nonsurjective calculus, quiver, duality, finite group, bimodule connection. 1. Introduction Noncommutative differential geometry is an extension of geometry to the case where the coordinate algebra A may be noncommutative or “quantum.” The starting point is a “differential structure” on A defined as a pair .1; d/ where the space of “1-forms” 1 is an A-A-bimodule (so one can multiply by the algebra from the left or the right) and d A 1 obeys the Leibniz rule. -

What Makes a Good Descriptor for Heterogeneous Ice Nucleation on OH-Patterned Surfaces
What Makes a Good Descriptor for Heterogeneous Ice Nucleation on OH-Patterned Surfaces Philipp Pedevilla Thomas Young Centre and London Centre for Nanotechnology, 17-19 Gordon Street, London, WC1H 0AH, United Kingdom and Department of Chemistry, University College London, 20 Gordon Street, London, WC1H 0AJ, United Kingdom Martin Fitzner and Angelos Michaelides∗ Thomas Young Centre and London Centre for Nanotechnology, 17-19 Gordon Street, London, WC1H 0AH, United Kingdom and Department of Physics and Astronomy, University College London, Gower Street, London, WC1E 6BT, United Kingdom (Dated: October 5, 2018) Freezing of water is arguably one of the most common phase transitions on Earth and almost always happens heterogeneously. Despite its importance, we lack a fundamental understanding of what makes substrates efficient ice nucleators. Here we address this by computing the ice nucleation (IN) ability of numerous model hydroxylated substrates with diverse surface hydroxyl (OH) group arrangements. Overall, for the substrates considered, we find that neither the symmetry of the OH patterns nor the similarity between a substrate and ice correlate well with the IN ability. Instead, we find that the OH density and the substrate-water interaction strength are useful descriptors of a material's IN ability. This insight allows the rationalization of ice nucleation ability across a wide range of materials, and can aid the search and design of novel potent ice nucleators in the future. I.

Public Request to Take Stronger Measures of Social Distancing Across the UK with Immediate Effect 14Th March 2020
Public request to take stronger measures of social distancing across the UK with immediate effect 14th March 2020 (last update: 15th March 2020, 18:25) As scientists living and working in the UK, we would like to express our concern about the course of action announced by the Government on 12th March 2020 regarding the Coronavirus outbreak. In particular, we are deeply preoccupied by the timeline of the proposed plan, which aims at delaying social distancing measures even further. The current data about the number of infections in the UK is in line with the growth curves already observed in other countries, including Italy, Spain, France, and Germany [1]. The same data suggests that the number of infected will be in the order of dozens of thousands within a few days. Under unconstrained growth, this outbreak will affect millions of people in the next few weeks. This will most probably put the NHS at serious risk of not being able to cope with the flow of patients needing intensive care, as the number of ICU beds in the UK is not larger than that available in other neighbouring countries with a similar population [2]. Going for \herd immunity" at this point does not seem a viable option, as this will put NHS at an even stronger level of stress, risking many more lives than necessary. By putting in place social distancing measures now, the growth can be slowed down dramatically, and thousands of lives can be spared. We consider the social distancing measures taken as of today as insufficient, and we believe that addi- tional and more restrictive measures should be taken immediately, as it is already happening in other countries across the world. -

The conference series \New Frontiers in Physics" aims to promote interdisciplinarity and cross-fertilization of ideas between different disciplines addressing fundamental physics. 1 Introduction While different fields each face a distinct set of field-specific challenges in the coming decade, a significant set of commonalities has emerged in the technical nature of some of these challenges, or are underlying the fundamental concepts involved. A Grand Unified Theory should in principle reveal this underlying relationship. -

Yet, its role is not fully clear, for which reason an extensive project is being carried out at MPIE (see highlight article on page 113). As a part of this project, deformation structures in gum metal (Ti−22.6Nb−0.47Ta−1.85Zr−1.34O at%) are compared to those in a reference alloy that has the same chemical composition, but no oxygen (Ti−22.8Nb−0.5Ta−1.8Zr at%). The cover page shows a light microscope image of a sample of the reference alloy deformed in uniaxial tension, revealing mechanically-induced crystallographic twin steps on a priorly-polished surface (1 cm corresponds to approx. 125 µm).
