Bregman Itoh–Abe Methods for Sparse Optimisation
In this paper we propose optimisation methods for variational regularisation
problems based on discretising the inverse scale space flow with discrete
gradient methods. Inverse scale space flow generalises gradient flows...
What are the optimum components in a care bundle aimed at reducing post-operative pulmonary complications in high-risk patients?
Sophie V Griffiths, Daniel H Conway, POPC-CB Investigators, Michael Sander, Ib Jammer, Michael PW Grocott, Ben C Creagh-Brown
Apr 28, 2020
BACKGROUND: Post-operative pulmonary complications (POPC) are common, predictable and associated with increased morbidity and mortality, independent of pre-operative risk. Interventions to reduce the incidence of POPC have been...
A Geometric Integration Approach to Nonsmooth, Nonconvex Optimisation
The optimisation of nonsmooth, nonconvex functions without access to
gradients is a particularly challenging problem that is frequently encountered,
for example in model parameter optimisation problems. Bilevel optimisation...
Task adapted reconstruction for inverse problems
The paper considers the problem of performing a task defined on a model
parameter that is only observed indirectly through noisy data in an ill-posed
inverse problem. A key aspect is to formalize the steps of reconstruction...
Dynamic Interfacial Adhesion through Cucurbit[n]uril Molecular Recognition.
Supramolecular building blocks, such as cucurbit[n]uril (CB[n])-based host-guest complexes, have been extensively studied at the nano- and microscale as adhesion promoters. Herein, we exploit a new class of CB[n]-threaded highly...
Modular supramolecular dimerization of optically tunable extended aryl viologens.
Magdalena Olesińska, Guanglu Wu, Silvia Gómez-Coca, Daniel Antón-García, Istvan Szabó, Edina Rosta, Oren A Scherman
Jan 06, 2020
Cucurbit[8]uril (CB[8]) mediated assembly of extended aryl viologens (EVs) into optically tunable dimers is reported for the first time. We show that the modular design and synthesis of a new class of π-conjugated viologen...
The Temperature Role in the Manufacturing of an Electrode for Supercapacitors with Carbon Black and Graphene Oxide
Supercapacitors (SCs) are energy storage devices with a growing interest thanks to their high-power charge and discharge process and long-cycle life. Their main drawback, when compared to more common devices such as batteries...
Host-Guest Chemistry Meets Electrocatalysis
Andreas Wagner, Khoa H Ly, Nina Heidary, István Szabó, Tamás Földes, Khaleel I Assaf, Steven J Barrow, Kamil Sokołowski, Mohamed Al-Hada, Nikolay Kornienko, Moritz F Kuehnel, Edina Rosta, Ingo Zebger, Werner M Nau, Oren A Scherman, Erwin Reisner
Feb 14, 2020
The rational control of forming and stabilizing reaction intermediates to guide specific reaction pathways remains to be a major challenge in electrocatalysis. In this work, we report a surface active-site engineering approach...

An anisotropic interaction model for simulating fingerprints.
Bertram Düring, Carsten Gottschlich, Stephan Huckemann, Lisa Maria Kreusser, Carola-Bibiane Schönlieb
Feb 18, 2019
Evidence suggests that both the interaction of so-called Merkel cells and the epidermal stress distribution play an important role in the formation of fingerprint patterns during pregnancy. To model the formation of fingerprint...
Hybrid organic-inorganic supramolecular hydrogel reinforced with CePO4 nanowires
We report a method to enhance the stiffness in the rheological yield strain of cucurbit[8]uril (CB[8])-based hydrogels by introducing inorganic nanowires (NWs) into the supramolecular networks. The supramolecular hydrogel is...
Are biologics more effective than corticosteroids for intra‐articular treatment of osteoarthritis?
Summary: Intra‐articular corticosteroids are an effective treatment for equine osteoarthritis, however, there is increasing evidence for the effectiveness of other treatments such as biologics. Whilst current evidence does...
Γ-Convergence of an Ambrosio-Tortorelli approximation scheme for image segmentation
Given an image u0, the aim of minimising the Mumford-Shah functional is to find a decomposition of the image domain into sub-domains and a piecewise smooth approximation u of u0 such that u varies smoothly within each...
Tough Supramolecular Polymer Networks with Extreme Stretchability and Fast Room-Temperature Self-Healing.
Recent progress on highly tough and stretchable polymer networks has highlighted the potential of wearable electronic devices and structural biomaterials such as cartilage. For some given applications, a combination of desirable...
