Canonical positions for the factors in paperfolding sequences

Theoretical Computer Science, 1994
A paper-folding sequence, \(u(n)\), is obtained by repeatedly folding a piece of paper in half according to a sequence of folding instructions (left half over right or right over left). If the paper is unfolded, the terms of the sequence can be seen to be \(u(n) =0\) or 1 according as the fold goes down or up.

3D Positional Integration from Image Sequences [PDF]

Procedings of the Alvey Vision Conference 1987, 1987
Abstract An explicit three-dimensional (3D) representation is constructed from feature points extracted from a sequence of images taken by a moving camera. The points are tracked through the sequence, and their 3D locations are accurately determined by use of Kalman filters. The egomotion of the camera is also determined.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Difference Sets and Positive Exponential Sums I. General Properties [PDF]

, 2014
We describe general connections between intersective properties of sets in Abelian groups and positive exponential sums. In particular, given a set A the maximal size of a set whose difference set avoids A will be related to positive exponential sums ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Sequence analysis and genomic organization of Aphid lethal paralysis virus: a new member of the family Dicistroviridae [PDF]

, 2002
The complete nucleotide sequence of the genomic RNA of an aphid-infecting virus, Aphid lethal paralysis virus (ALPV), has been determined. The genome is 9812 nt in length and contains two long open reading frames (ORFs), which are separated by an ...

An Improved Directional Relay Adapted to a Distribution Network with IIG Integration

Energies, 2019
The integration of distributed generation (DG) into a distribution network changes the network’s topology. Three-stage current protection for a radial distribution network cannot meet the requirements of relay protection for a distribution network ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...
