Bayesian sensitivity analysis with the Fisher–Rao metric (2015)
Journal Article
Kurtek, S., & Bharath, K. (2015). Bayesian sensitivity analysis with the Fisher–Rao metric. Biometrika, 102(3), https://doi.org/10.1093/biomet/asv026

We propose a geometric framework to assess sensitivity of Bayesian procedures to modelling assumptions based on the nonparametric Fisher–Rao metric. While the framework is general, the focus of this article is on assessing local and global robustness... Read More about Bayesian sensitivity analysis with the Fisher–Rao metric.

Ripple compensation for a class-D amplifier (2015)
Journal Article
Cox, S. M., & du Toit Mouton, H. (2015). Ripple compensation for a class-D amplifier. SIAM Journal on Applied Mathematics, 75(4), https://doi.org/10.1137/140997695

This paper presents the first detailed mathematical analysis of the ripple compensation technique for reducing audio distortion in a class-D amplifier with negative feedback. The amplifier converts a relatively low-frequency audio signal to a high-fr... Read More about Ripple compensation for a class-D amplifier.

(1+1)D calculation provides evidence that quantum entanglement survives a firewall (2015)
Journal Article
Martín-Martínez, E., & Louko, J. (2015). (1+1)D calculation provides evidence that quantum entanglement survives a firewall. Physical Review Letters, 115(3), Article 031301. https://doi.org/10.1103/PhysRevLett.115.031301

We analyze how preexisting entanglement between two Unruh-DeWitt particle detectors evolves when one of the detectors falls through a Rindler firewall in (1+1)-dimensional Minkowski space. The firewall effect is minor and does not wash out the detect... Read More about (1+1)D calculation provides evidence that quantum entanglement survives a firewall.

Ca²⁺ Channel Re-localization to Plasma-Membrane Microdomains Strengthens Activation of Ca2+-Dependent Nuclear Gene Expression (2015)
Journal Article
Samanta, K., Kar, P., Mirams, G. R., & Parekh, A. B. (2015). Ca²⁺ Channel Re-localization to Plasma-Membrane Microdomains Strengthens Activation of Ca2+-Dependent Nuclear Gene Expression. Cell Reports, 12(2), 203-216. https://doi.org/10.1016/j.celrep.2015.06.018

In polarized cells or cells with complex geometry, clustering of plasma-membrane (PM) ion channels is an effective mechanism for eliciting spatially restricted signals. However, channel clustering is also seen in cells with relatively simple topology...

Stability of neuronal networks with homeostatic regulation (2015)
Journal Article
Harnack, D., Pelko, M., Chaillet, A., Chitour, Y., & van Rossum, M. C. (2015). Stability of neuronal networks with homeostatic regulation. PLoS Computational Biology, 11(7), Article e1004357. https://doi.org/10.1371/journal.pcbi.1004357

Neurons are equipped with homeostatic mechanisms that counteract long-term perturbations of their average activity and thereby keep neurons in a healthy and information-rich operating regime. While homeostasis is believed to be crucial for neural fun... Read More about Stability of neuronal networks with homeostatic regulation.

Measuring quantum coherence with entanglement (2015)
Journal Article
Streltsov, A., Singh, U., Dhar, H. S., Bera, M. N., & Adesso, G. (2015). Measuring quantum coherence with entanglement. Physical Review Letters, 115(2), Article 020403. https://doi.org/10.1103/PhysRevLett.115.020403

Quantum coherence is an essential ingredient in quantum information processing and plays a central role in emergent fields such as nanoscale thermodynamics and quantum biology. However, our understanding and quantitative characterization of coherence... Read More about Measuring quantum coherence with entanglement.

Noise promotes independent control of gamma oscillations and grid firing within recurrent attractor networks (2015)
Journal Article
Solanka, L., van Rossum, M. C., & Nolan, M. F. (in press). Noise promotes independent control of gamma oscillations and grid firing within recurrent attractor networks. eLife, 4, Article e06444. https://doi.org/10.7554/eLife.06444

Neural computations underlying cognitive functions require calibration of the strength of excitatory and inhibitory synaptic connections and are associated with modulation of gamma frequency oscillations in network activity. However, principles relat... Read More about Noise promotes independent control of gamma oscillations and grid firing within recurrent attractor networks.

Random coupling model for the radiation of irregular apertures (2015)
Journal Article
Gradoni, G., Antonsen, T., & Ott, E. (2015). Random coupling model for the radiation of irregular apertures. Radio Science, 50(7), 678-687. https://doi.org/10.1002/2014RS005577

In this work, we extend results on the coupling of radiation through apertures inside wave chaotic electromagnetic cavities to the short?wavelength limit. The aperture is assumed to have irregular and smooth boundary geometry. A statistical approach... Read More about Random coupling model for the radiation of irregular apertures.
