Divergence and Sufficiency for Convex Optimization
Logarithmic score and information divergence appear in information theory, statistics, statistical mechanics, and portfolio theory. We demonstrate that all these topics involve some kind of optimization that leads directly to regret functions and such ...

Statistical Analysis of Distance Estimators with Density Differences and Density Ratios
Estimating a discrepancy between two probability distributions from samples is an important task in statistics and machine learning. There are mainly two classes of discrepancy measures: distance measures based on the density difference, such as the Lp ...

The link between colorfulness and extinction risk across the world's passerine birds
Abstract Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as coloration directly affect human interactions with wildlife.

Sound offset responses become highly informative in the auditory cortex
Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...

Distinctive neurophysiological correlates of sound onset and offset perception in humans
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...

On the Joint Convexity of the Bregman Divergence of Matrices [PDF]
We characterize the functions for which the corresponding Bregman divergence is jointly convex on matrices. As an application of this characterization, we derive a sharp inequality for the quantum Tsallis entropy of a tripartite state, which can be considered as a generalization of the strong subadditivity of the von Neumann entropy.

Replacement soaking for human tankyrase 2 enables studies on substrate analogues and inhibitors
Replacement soaking, also known as cross‐soaking, is a compelling method for solving complex structures in cases where traditional soaking and co‐crystallization approaches fail. This method is demonstrated with human tankyrase 2, and new crystal structures of complexes with nanomolar inhibitors and an analogue of the substrate NAD+ are reported ...

The Duality of Entropy/Extropy, and Completion of the Kullback Information Complex
The refinement axiom for entropy has been provocative in providing foundations of information theory, recognised as thoughtworthy in the writings of both Shannon and Jaynes.
