On the Reliability Function for a BSC with Noiseless Feedback at Zero Rate
Problems of Information Transmission, 2022 We consider the transmission of nonexponentially many messages through a binary symmetric channel with noiseless feedback. We obtain an upper bound for the best decoding error exponent. Combined with the corresponding known lower bound, this allows to find the reliability function for this channel at zero rate.

Media Tone: The Role of News and Social Media on Heterogeneous Inflation Expectations
Journal of Forecasting, Volume 44, Issue 3, Page 881-921, April 2025.ABSTRACT This study investigates the role of media tone on inflation expectations. Examining the relationships between news and the inflation expectations of various US demographic groupings, we find that traditional news influences older cohorts, whereas social media news align more closely with the expectations of younger and more educated groups ...

Boosting reliability over AWGN networks with average power constraints and noiseless feedback [PDF]
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005 For the point-to-point additive white Gaussian noise (AWGN) channel with noiseless feedback and an average power constraint, Schalkwijk and Kailath's scheme achieves a doubly-exponential decay of the probability of error. While some coding schemes for networks with noiseless feedback incorporate variations on the Schalkwijk-Kailath scheme, they do not ...

InstaMap: instant‐NGP for cryo‐EM density maps
Acta Crystallographica Section D, Volume 81, Issue 4, Page 147-169, April 2025.Cryo‐EM density‐map inference, with fixed pose and contrast transfer function, using a multi‐resolution hash‐encoding framework called instant‐NGP, is described, together with its extension to heterogeneity inference by bending space with a per‐image vector field.Despite the parallels between problems in computer vision and cryo‐electron microscopy ...

The Locus Coeruleus: Anatomy, Physiology, and Stress‐Related Neuropsychiatric Disorders
European Journal of Neuroscience, Volume 61, Issue 7, April 2025.Repeated and chronic exposure to stressors may activate the locus coeruleus–norepinephrine (LC‐NE) system. Depression and post‐traumatic stress disorders precipitated by a stressful event are associated with the hypersecretion of the corticotropin‐releasing factor (CRF) leading to elevated CRF levels in the brain (green arrows pointed up).

The Journal of Physiology, Volume 603, Issue 8, Page 2281-2300, 15 April 2025.Abstract figure legend Schematic of Swarm‐Contrastive Decomposition. A set of separation vectors are initialised to the same vector, with zero‐mean and unitary standard deviation. Each separation vector is associated with a specific particle, the value of the exponent in the contrast function.

A novel class of adaptive observers for dynamic nonlinear uncertain systems
Expert Systems, Volume 42, Issue 1, January 2025.Abstract Numerous techniques have been proposed in the literature to improve the performance of high‐gain observers with noisy measurements. One such technique is the linear extended state observer, which is used to estimate the system's states and to account for the impact of internal uncertainties, undesirable nonlinearities, and external ...
