Isotropic Sequence Order Learning [PDF]

Neural Computation, 2003
In this article, we present an isotropic unsupervised algorithm for temporal sequence learning. No special reward signal is used such that all inputs are completely isotropic. All input signals are bandpass filtered before converging onto a linear output neuron.

Isotropic and Non-Isotropic Signaling in Multivariate α-Stable Noise

Frontiers in Communications and Networks, 2021
A wide range of communication systems are corrupted by non-Gaussian noise, ranging from wireless to power line. In some cases, including interference in uncoordinated OFDM-based wireless networks, the noise is both impulsive and multivariate. At present,

Colonial policy, ecological transformations, and agricultural “improvement”: comparing agricultural yields and expansion in the Spanish and U.S. Philippines, 1870–1925 CE

Humanities & Social Sciences Communications
Burgeoning global trade and colonial policies promoted transformations in land use and agriculture throughout tropical regions in the 19th and 20th centuries, but the local and regional ecological consequences of landscape changes are still being ...

Effects of nongaussian diffusion on "isotropic diffusion measurements'': an ex-vivo microimaging and simulation study

, 2019
Designing novel diffusion-weighted pulse sequences to probe tissue microstructure beyond the conventional Stejskal-Tanner family is currently of broad interest.

Gauge invariant perturbations around symmetry reduced sectors of general relativity: applications to cosmology [PDF]

, 2007
We develop a gauge invariant canonical perturbation scheme for perturbations around symmetry reduced sectors in generally covariant theories, such as general relativity.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Exploring tropical forest aboveground carbon dynamics via modelled landscapes of varied food production, past and present

Plants, People, Planet
Societal Impact Statement Contemporary land use studies often place food production in direct conflict with tropical forests, with forest land use for human needs exiting in conflict with carbon‐related forest conservation and biodiversity protection ...

2D CNN-Based Slices-to-Volume Superresolution Reconstruction

IEEE Access, 2020
In the case of slice-to-volume reconstruction, the usual method is to head up the slices according to their relative positions. However, it is common that the space between two scanned slices is more than the interval of the pixels on each slice, leading

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
