Dual-function engineering to construct ultra-stable anodes for potassium-ion hybrid capacitors: N, O-doped porous carbon spheres

Kangning Zhao, Yanan Chen, Chao Yang, Jie Xu, Xin Peng, Wen Liu, Wei Zhou

Heteroatom doping engineering is deemed to be an adoptable strategy to boost the potassium (K) storage performance of carbonaceous materials. The inevitable issue for this strategy lies in the huge volume expansion originated from the large radius of K+. I ...

Identifying a Motivational Profile for Older Adults Towards Increased Physical Activity

Pearl Pu Faltings, Yuan Lu

Personalizing behavior change (BC) strategies to motivate increased physical activity is especially important for the diverse older adult population. However, there is a lack of knowledge about how to profile older users to most effectively personalize BC ...

A synchrotron X-ray imaging strategy to map large animal brains

Giorgio Margaritondo, Ying Chen

Mapping the large neural networks of animal and human brains is a fundamental but so far elusive task, because of the massive amount of data and the consequent prohibitively long image taking and processing times. We developed an effective strategy called ...

Sensor and the Beast: Generalised Methods to Recognise Animal Behaviour and Quantify Energy Expenditure Using Inertial Sensors, and Applications

Pritish Chakravarty

How an animal allocates time and energy to different activities has repercussions for its survival, fitness, and response to changing environmental conditions. Fine-scale information on animal behaviour and energy expenditure can help develop better inform ...

Reduction of the sign problem near T=0 in quantum Monte Carlo simulations

Frédéric Mila, Jonathan D'Emidio

Building on a recent investigation of the Shastry-Sutherland model [S. Wessel et al., Phys. Rev. B 98, 174432 (2018)], we develop a general strategy to eliminate the Monte Carlo sign problem near the zero-temperature limit in frustrated quantum spin models ...

A hybrid niobium-based oxide with bio-based porous carbon as an efficient electrocatalyst in photovoltaics: a general strategy for understanding the catalytic mechanism

Ulf Anders Hagfeldt, Sining Yun, Cheng Wang

Developing a high-performance catalyst and establishing a catalytic mechanism for understanding the catalytic activity are crucial to new generation photovoltaic technology. In this work, we present a feasible and general route to synthesize a bio-based po ...

On Risk Reduction in Kelly Betting Using the Conservative Expected Value

Daniel Kuhn, Napat Rujeerapaiboon

The celebrated Kelly betting strategy guarantees, with probability one, higher long-run wealth than any other causal investment strategy. However, on the way to its long-term supremacy, this strategy has a notable downfall: it typically displays high varia ...

Distributed State Estimation and Cooperative Path-Following Under Communication Constraints

Francisco Fernandes Castro Rego

The main topics of this thesis are distributed estimation and cooperative path-following in the presence of communication constraints, with applications to autonomous marine vehicles. To this end, we study algorithms that take explicitly into account the c ...

Classical Force Fields Tailored for QM Applications: Is It Really a Feasible Strategy?

Oliviero Andreussi

Classical molecular dynamics is more and more often coupled to quantum mechanical based techniques as a statistical tool to sample configurations of molecular systems embedded in complex environments. Nonetheless, the classical potentials describing the mo ...

Compact and General Strategy for Solving Current and Potential Distribution in Electrochemical Cells Composed of Massive Monopolar and Bipolar Electrodes

Hubert Girault, Alejandro Nicolás Colli

A compact, fast and general algorithm based on Dirichlet boundary conditions for the potential field is derived to enable the calculation of local current distribution, shunt currents and the local potential distribution on massive electrodes in electroche ...

Simulation of energy recovery on water utility networks by a micro-turbine with counter-rotating runners

François Avellan, Vlad Hasmatuchi, Elena Vagnoni, Loïc Andolfatto, Cécile Münch-Alligné

Wherever relief valves and other energy dissipation devices are installed to limit the pressure, water utility networks provide unexploited hydropower potentials. This is mainly due to a lack of economically viable technologies for energy recovery in the p ...

CO2 capture in amine solutions: modelling and simulations with non-empirical methods

Wanda Andreoni, Fabio Pietrucci

Absorption in aqueous amine solutions is the most advanced technology for the capture of CO2, although suffering from drawbacks that do not allow exploitation on large scale. The search for optimum solvents has been pursued with empirical methods and has a ...

A novel strategy for reversible hydrogen storage in Ca(BH4)(2)

Andreas Züttel

We report that decomposition pathway of Ca(BH4)(2) can be efficiently controlled by reaction temperature. That is, it decomposes into CaB6 at a lower temperature range of 320 to 350 degrees C, but into amorphous boron at 400 to 450 degrees C. We identified ...

Efficient Scanning for EM Based Target Localization

Pascal Fua, Graham Knott, Raphael Sznitman, Aurélien Lucchi, Natasa Pjescic-Emedi

For biologists studying the morphology of cells, Electron Microscopy (EM) is the method of choice with its {\it nm} resolution, across increasingly larger volumes. However, the time necessary to acquire such image series is long and often limits the amount ...

A two-level time step technique for the partitioned solution of one-dimensional arterial networks

Simone Deparis, Adelmo Cristiano Innocenza Malossi

In this work a numerical strategy to address the solution of the blood flow in one-dimensional arterial networks through a topology-based decomposition is presented. Such decomposition results in the local analysis of the blood flow in simple arterial segm ...

Coopetition In The Global Book Industry: The Case Of Amazon.Com’s Evolution

Alain Wegmann, Arash Golnam

Coopetition (collaboration between competing firms) is a phenomenon which has recently captured a great deal of attention due to its increasing relevance to business practice. The current research on coopetition is still short in explaining how the potenti ...

A Framework to Model and Analyze the WHY and the HOW of Coopetition

Alain Wegmann, Arash Golnam, Ron Sanchez

Coopetition has been defined as an approach to managing that combines competition and cooperation. It transcends the traditional paradigms of competition and cooperation in an effort to achieve the advantages of both. As an inter-organizational relationshi ...
