Fast computation of soft tissue thermal response under deformation based on fast explicit dynamics finite element algorithm for surgical simulation. (arXiv:1911.11845v1 [cs.CE])

During thermal heating surgical procedures such as electrosurgery, thermal ablative treatment and hyperthermia, soft tissue deformation due to tool-tissue interaction and patients’ motion can affect the distribution of induced thermal energy. Tissue temperature must be efficiently and accurately obtained from deformed tissues for precise thermal energy delivery; however, the classical Pennes bio-heat transfer can handle…

Rule Designs for Optimal Online Game Matchmaking. (arXiv:1911.11852v1 [cs.PF])

Online games are the most popular form of entertainment among youngsters as well as elders. Recognized as e-Sports, they may become an official part of the Olympic Games by 2020. However, a long waiting time for matchmaking will largely affect players’ experiences. We examine different matchmaking mechanisms for 2v2 games. By casting the mechanisms into…

Neural Percussive Synthesis Parameterised by High-Level Timbral Features. (arXiv:1911.11853v1 [eess.AS])

We present a deep neural network-based methodology for synthesising percussive sounds with control over high-level timbral characteristics of the sounds. This approach allows for intuitive control of a synthesizer, enabling the user to shape sounds without extensive knowledge of signal processing. We use a feedforward convolutional neural network-based architecture, which is able to map input…

High accuracy and error analysis of indoor visible light positioning algorithm based on image sensor. (arXiv:1911.11773v1 [eess.SP])

In recent years, with the increasing demand for indoor positioning service, visible light indoor positioning based on image sensors has been widely studied. However, many researches only put forward the relevant localization algorithm and did not make a deep discussion on the principle of the visible light localization. In this paper, we make a deep…

Improving Polyphonic Music Models with Feature-Rich Encoding. (arXiv:1911.11775v1 [cs.SD])

This paper explores sequential modeling of polyphonic music with deep neural networks. While recent breakthroughs have focussed on network architecture, we demonstrate that the representation of the sequence can make an equally significant contribution to the performance of the model as measured by validation set loss. By extracting salient features inherent to the dataset, the…

Radiative Auger Process in the Single Photon Limit on a Quantum Dot. (arXiv:1911.11784v1 [cond-mat.mes-hall])

In a multi-electron atom, an excited electron can decay by emitting a photon. Typically, the leftover electrons are in their ground state. In a radiative Auger process, the leftover electrons are in an excited state and a red-shifted photon is created. In a quantum dot, radiative Auger is predicted for charged excitons. For a singly-charged…

Proton Irradiation-Decelerated Intergranular Corrosion of Ni-Cr Alloys in Molten Salt. (arXiv:1911.11798v1 [physics.app-ph])

The effects of ionizing radiation on materials often reduce to “bad news.” Radiation damage usually leads to detrimental effects such as embrittlement, accelerated creep, phase instability, and radiation-altered corrosion. This last point merits special attention. Elucidating synergies between radiation and corrosion has been one of the most challenging tasks impeding the deployment of advanced reactors,…

Complete theory of Ramsey interferometry with squeezing echos. (arXiv:1911.11801v1 [quant-ph])

We consider a large class of Ramsey interferometry protocols which are enhanced by squeezing and un-squeezing operations before and after a phase signal is imprinted on the collective spin of $N$ particles. We report an analytical optimization for any given particle number and strengths of (un-)squeezing, including experimentally relevant decoherence processes. This provides a complete…
