Heat transfer analysis in an uncoiled model of the cochlea during magnetic cochlear implant surgery. (arXiv:1911.11889v1 [physics.med-ph])

Magnetic cochlear implant surgery requires removal of a magnet via a heating process after implant insertion, which may cause thermal trauma within the ear. Intra-cochlear heat transfer analysis is required to ensure that the magnet removal phase is thermally safe. The objective of this work is to determine the safe input power density to detach…

On the extended use of Backus average. (arXiv:1911.11896v1 [physics.class-ph])

Backus (1962) developed his technique for homogenization of a layered structure solely within the context of linear elastic theory. In this paper we propose an extended use of Backus average for finitely deformed materials of a layered structure. We attempt to use two different approaches to account for large deformations. The first approach utilizes the…

Design of a testbed for the study of system interference in space CMB polarimetry. (arXiv:1911.11902v1 [astro-ph.IM])

LiteBIRD is a proposed JAXA satellite mission to measure the CMB B-mode polarization with unprecedented sensitivity ($\sigma_r\sim 0.001$). To achieve this goal, $4676$ state-of-the-art TES bolometers will observe the whole sky for 3 years from L2. These detectors, as well as the SQUID readout, are extremely susceptible to EMI and other instrumental disturbances e.g. static…

Space-Ground Coherent Optical links: Ground Receiver Performance With Adaptive Optics and Digital Phase-Locked Loop. (arXiv:1911.11851v1 [eess.SP])

In the framework of optical high data rate satellite-to-ground links, we investigate the performance of a coherent receiver which combines an adaptive optics system and a digital carrier synchronization technique. We propose a digital carrier synchronization system based on a phase-locked loop and use end-to-end simulations to characterize the impact of the atmospheric turbulence in…

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…

Compressed MRI Reconstruction Exploiting a Rotation-Invariant Total Variation Discretization. (arXiv:1911.11854v1 [eess.IV])

Inspired by the first-order method of Malitsky and Pock, we propose a novel variational framework for compressed MR image reconstruction which introduces the application of a rotation-invariant discretization of total variation functional into MR imaging while exploiting BM3D frame as a sparsifying transform. The proposed model is presented as a constrained optimization problem, however, we…

The Effect of Salt Shock on Growth and Pigment Accumulation of Dunaliella Salina. (arXiv:1911.11840v1 [q-bio.QM])

Dunaliella Salina is a halotolerant microalga with great pharmaceutical and industrial potential, which commonly exists in hypersaline environments. Moreover, it is the best commercial source of beta-carotene (which has high anti-oxidant properties) in comparison to other microalgae. In this study, we investigated growth and accumulations of chlorophyll a and b, beta-carotene, and carotenoid after salt…

Design Efficient Exponential Time Differencing method For Hodgkin-Huxley Neural Networks. (arXiv:1910.08724v4 [q-bio.NC] UPDATED)

The exponential time differencing (ETD) method allows using a large time step to efficiently evolve the stiff system such as Hodgkin-Huxley (HH) neural networks. For pulse-coupled HH networks, the synaptic spike times cannot be predetermined and are convoluted with neuron’s trajectory itself. This presents a challenging issue for the design of an efficient numerical simulation…

Quantum-classical duality for Gaudin magnets with boundary. (arXiv:1911.11792v1 [math-ph])

We establish a remarkable relationship between the quantum Gaudin models with boundary and the classical many-body integrable systems of Calogero-Moser type associated with the root systems of classical Lie algebras (B, C and D). We show that under identification of spectra of the Gaudin Hamiltonians $H_j^{\rm G}$ with particles velocities $\dot q_j$ of the classical…
