Annual Review 2016/17 Pushing at the frontiers of Knowledge Portrait of Dr Henry Odili Nwume (Brasenose) by Sarah Jane Moon – see The Full Picture, page 17. FOREWORD 2016/17 has been a memorable year for the country and for our University. In the ever-changing and deeply uncertain world around us, the University of Oxford continues to attract the most talented students and the most talented academics from across the globe. They convene here, as they have always done, to learn, to push at the frontiers of knowledge and to improve the world in which we find ourselves. One of the highlights of the past twelve months was that for the second consecutive year we were named the top university in the world by the Times Higher Education Global Rankings. While it is reasonable to be sceptical of the precise placements in these rankings, it is incontrovertible that we are universally acknowledged to be one of the greatest universities in the world. This is a privilege, a responsibility and a challenge. Other highlights include the opening of the world’s largest health big data institute, the Li Ka Shing Centre for Health Information and Discovery, and the launch of OSCAR – the Oxford Suzhou Centre for Advanced Research – a major new research centre in Suzhou near Shanghai. In addition, the Ashmolean’s success in raising £1.35 million to purchase King Alfred’s coins, which included support from over 800 members of the public, was a cause for celebration. The pages that follow detail just some of the extraordinary research being conducted here on perovskite solar cells, indestructible tardigrades and driverless cars. -
Ingredients for Success 18Th HFSP Awardees Meeting
Ingredients for success In 2018, we yet again embarked on a new era in the HFSP by Guntram Bauer Fellowship program. After careful internal discussion and HFSPO Director of Scientific Affairs and Communications preparations, the review committee was presided over by a non- reviewing chair. Peter Koopman from the Institute of Molecular Bioscience of the University of Queensland took center stage as chair of this committee. Peter finished a four year tenure as a member of the fellowship review committee in 2016 and arrived back in Strasbourg after a three month sailing trip in the southern Pacific. Peer review at HFSP is not reading tea leaves but serious and demanding work for all involved. Thanks to Peter Koopman we successfully completed the first fellowship review committee run by a non-reviewing chair. We are still not sure what the magic ingredient was that made this fellowship committee stand out. Whether it was a truly committed international review panel, or the drive and oversight of its non-reviewing chair, or simply because of the HFSP Sauce which arrived in the chair's suitcase in Strasbourg. Probably all three, though be assured that we will get to the bottom of the HFSP Sauce! I don’t think we are boasting about HFSP when we say that our Program always tries to synchronize its procedures with the dynamics at the frontiers of science. This is particularly true for our peer review process. Over many years we have made more than just subtle changes to our procedures in response to feedback from the scientific community. -

Chapter 6 the Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930S
Trafficking Materials and Maria Rentetzi Gendered Experimental Practices Chapter 6 The Aftermath of the Cambridge-Vienna Controversy: Radioactivity and Politics in Vienna in the 1930s Consequences of the Cambridge-Vienna episode ranged from the entrance of other 1 research centers into the field as the study of the atomic nucleus became a promising area of scientific investigation to the development of new experimental methods. As Jeff Hughes describes, three key groups turned to the study of atomic nucleus. Gerhard Hoffman and his student Heinz Pose studied artificial disintegration at the Physics Institute of the University of Halle using a polonium source sent by Meyer.1 In Paris, Maurice de Broglie turned his well-equipped laboratory for x-ray research into a center for radioactivity studies and Madame Curie started to accumulate polonium for research on artificial disintegration. The need to replace the scintillation counters with a more reliable technique also 2 led to the extensive use of the cloud chamber in Cambridge.2 Simultaneously, the development of electric counting methods for measuring alpha particles in Rutherford's laboratory secured quantitative investigations and prompted Stetter and Schmidt from the Vienna Institute to focus on the valve amplifier technique.3 Essential for the work in both the Cambridge and the Vienna laboratories was the use of polonium as a strong source of alpha particles for those methods as an alternative to the scintillation technique. Besides serving as a place for scientific production, the laboratory was definitely 3 also a space for work where tasks were labeled as skilled and unskilled and positions were divided to those paid monthly and those supported by grant money or by research fellowships. -

ABSTRACT Understanding how cellular functions emerge from the underlying molecular mechanisms is one of the principal challenges in biology. It is widely recognised that this will require computational methods, and we expect the predictive power of these models to increase as model coverage and precision of formulation increase. The most potent examples to date are the genome-scale metabolic models that revolutionised their field and paved the way for a bacterial whole-cell model. However, to realise the potential of whole-cell models for eukaryotes, we must enable genome-scale modelling of other cellular networks. This has proven particularly challenging for the cellular regulatory networks, i.e. -

Perturbations of Periodic Sturm-Liouville Operators

We study perturbations of the self-adjoint periodic Sturm{Liouville operator 1 d d A0 = − p0 + q0 r0 dx dx and conclude under L1-assumptions on the differences of the coefficients that the essential spectrum and absolutely continuous spectrum remain the same. If a finite first moment condition holds for the differences of the coefficients, then at most finitely many eigenvalues appear in the spectral gaps. This observation extends a seminal result by Rofe-Beketov from the 1960s. Finally, imposing a second moment condition we show that the band edges are no eigenvalues of the perturbed operator. 1. Introduction Consider a periodic Sturm{Liouville differential expression of the form 1 d d τ0 = − p0 + q0 r0 dx dx R 1 R on , where 1=p0; q0; r0 2 Lloc( ) are real-valued and !-periodic, and r0 > 0, p0 > 0 2 a. e. Let A0 be the corresponding self-adjoint operator in the weighted L -Hilbert 2 space L (R; r0) and recall that the spectrum of A0 is semibounded from below, purely absolutely continuous and consists of (finitely or infinitely many) spectral bands; cf. -

Reflectionless Operators: the Deift and Simon Conjectures
Mathematisches Forschungsinstitut Oberwolfach Report No. 49/2017 DOI: 10.4171/OWR/2017/49 Mini-Workshop: Reflectionless Operators: The Deift and Simon Conjectures Organised by David Damanik, Houston Fritz Gesztesy, Waco Peter Yuditskii, Linz 22 October – 28 October 2017 Abstract. Reflectionless operators in one dimension are particularly amen- able to inverse scattering and are intimately related to integrable systems like KdV and Toda. Recent work has indicated a strong (but not equivalent) relationship between reflectionless operators and almost periodic potentials with absolutely continuous spectrum. This makes the realm of reflectionless operators a natural place to begin addressing Deift’s conjecture on integrable flows with almost periodic initial conditions and Simon’s conjecture on gems of spectral theory establishing correspondences between certain coefficient and spectral properties. Mathematics Subject Classification (2010): 35Q53, 35B15, 47B36, 47A55. Introduction by the Organisers This mini-workshop was organized by David Damanik (Rice), Fritz Gesztesy (Bay- lor), and Peter Yuditskii (Linz). The program consisted of 15 lectures on a broad variety of problems related to the Deift and Simon conjectures, including pertur- bation theory, integrable systems, random matrix theory, character-automorphic Hardy spaces, and orthogonal polynomials. This workshop intended to provide a cutting-edge survey of new results for reflectionless operators, especially those results directed towards addressing Deift’s conjecture regarding the almost pe- riodicity of solutions to the KdV equation with almost-periodic initial data and Simon’s conjecture regarding gems of spectral theory establishing a one-to-one cor- respondence between suitable classes of coefficient data and spectral data. This 2944 Oberwolfach Report 49/2017 forum provided a great background for discussions of some of the extant open problems in the field.
