The Mathematical History Behind the Granger–Johansen Representation Theorem

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT When can a vector time series that is integrated once (i.e., becomes stationary after taking first differences) be described in error correction form? The answer to this is provided by the Granger–Johansen representation theorem. From a mathematical point of view, the theorem can be viewed as essentially a statement concerning the geometry of ...

First Tetraploa Genome and Multi‐Omics Analysis Reveal Key Plant‐Microbe‐Soil Interactions for Salt Tolerance and Yield Improvement of Wheat

Plant Biotechnology Journal, EarlyView.
ABSTRACT Salinity is a major threat to global agricultural productivity of staple crops such as wheat. Although microbial‐based solutions hold promise for alleviating salinity stress, practical implementation is hindered by insufficient mechanistic characterization of bioinoculants and their interactions with plants.

A New Hilbert's Hotel Argument Against Past‐Eternalism

Analytic Philosophy, EarlyView.
ABSTRACT This paper offers a new formulation of the “Hilbert's Hotel Argument” (HHA) which is superior to existing formulations because it (1) demonstrates that HH is logically impossible in the concrete world, (2) takes into account the need to consider the assumptions of HHA, and (3) offers a reply to an important objection concerning the validity of

Room for Improvement: Why Finitist Arguments Do Not Check Out

Analytic Philosophy, EarlyView.
ABSTRACT We examine several new and underexplored arguments for the finitude of the past and the impossibility of Hilbert's Hotel. The first argument concludes that Hilbert's Hotel is impossible due to an alleged contradiction arising from the causal powers of infinitely many guests.

Spatial depth for data in metric spaces

Scandinavian Journal of Statistics, EarlyView.
Abstract We propose a novel measure of statistical depth, the metric spatial depth, for data residing in an arbitrary metric space. The measure assigns high (low) values for points located near (far away from) the bulk of the data distribution, allowing quantifying their centrality/outlyingness.
