Class Angular Distortion Index for Dimensionality Reduction
Computer Graphics Forum, EarlyView.Abstract Dimensionality reduction (DR) techniques are often characterized by whether they preserve global, high‐level structures in the data or local, neighborhood structures. This distinction matters in visualization: global methods can obscure clusters while local methods can over‐emphasize them.

Scalable Computation of Topological Abstractions for Scalar Data
Computer Graphics Forum, EarlyView.Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Existence of quasi-periodic invariant tori for coupled van der Pol equations
Electronic Journal of Differential Equations, 2019 This work focuses on the existence of quasi-periodic invariant tori for coupled van der Pol equations. Using averaging method, a series of reversible transformations and KAM techniques, we prove that there exist quasi-periodic invariant tori for most

Conservation Biology, EarlyView.Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

A Survey on Bifurcations of Invariant Tori
, 2001 Invariant tori of dynamical systems occur both in the dissipative and in the conservative context. I focus here on the latter, where the tori are intrinsically parametrised by the actions y 1 ; : : : ; y n conjugate to the angles x 1 ; : : : ; x n on ...

The FEBS Journal, EarlyView.Polyphosphate interaction with Hfq and RNA drives phase separation and amyloid self‐assembly, uncovering a previously unrecognized role for polyP in bacterial stress responses. Our findings reveal new insights into the molecular mechanisms of RNA‐mediated phase separation, highlighting the role of polyP as a key modulator of this process. Polyphosphate

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces
International Statistical Review, EarlyView.Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Financialisation and Physical Investment: A global race to the bottom in accumulation?
, 2017 In this article we estimate the effects of financialisation on investment in the developed and developing countries using panel data based on balance-sheets of publicly listed non-financial companies (NFCs) supplied by Worldscope for the period 1995-2015.
