Harnessing Bulk‐Segregant Mapping to Identify Trait‐Associated Genes in the Allopolyploid Model Plant Nicotiana benthamiana

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Forward genetics has been instrumental in identifying genes underlying desirable traits, yet its application to polyploid plants, many of which are key agricultural crops, remains challenging due to their genomic complexity. Therefore, we developed BenthMap, a bulk segregant analysis platform for high‐throughput trait mapping and gene ...

Exploring the star formation histories of galaxies [PDF]

open access: yes, 1999
In this thesis, I explore the star formation histories of both spiral and elliptical galaxies. In Part 1,1 present an in-depth study of the star formation histories of spiral galaxies with a wide range of properties. Optical and near-infrared colours are

The collective origin of spiral structures in disk galaxies

open access: yesEPJ Web of Conferences, 2012
After almost fifty years the origin of spiral arms in disk galaxies remains one of the major unsolved problems in astrophysics. Recent attempts have indicated that substructures in the dark matter halos of galaxies could induce spiral patterns in disks ...

Genome‐wide prediction of cloned disease resistance homologues across the Oryza genus

open access: yesThe Plant Genome, Volume 19, Issue 4, December 2026.
Abstract The wild relatives of rice (Oryza sativa L.) represent reservoirs of genetic diversity and potential sources of novel pest and disease resistance. The recent availability of high‐quality Oryza genome assemblies has enabled greater exploration of this diversity across the genus.

Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

open access: yes, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

Gravitational Instability of Gas–Dust Circumnuclear Disks in Galaxies

open access: yesGalaxies, 2023
We numerically study the origin of the multi-armed spiral structure observed in the circumnuclear gaseous mini-disks of nearby galaxies. We show that the presence of dust in such disks and its interaction with the gravitationally stable gaseous component

Gastroschisis‐Like Defect in a Crossbred Bovine Calf: Anatomical, Clinical and Surgical Perspectives

open access: yesVeterinary Medicine and Science, Volume 12, Issue 6, November 2026.
A gastroschisis‐like defect was observed in a one‐day‐old, crossbred bovine calf with evisceration of the pyloric abomasum and small intestine, likely resulting from prenatal rupture of an omphalocele. The calf presented with lethargy, hypothermia and metabolic derangements, along with elevated renal biomarkers.

Dark Matter in Spiral Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1995
In this review I will concentrate on three questions concerning the issue of dark matter in spiral galaxies. In the first place (and for the most part) I will discuss the analysis of rotation curves and the question whether the “maximum–disk hypothesis” is valid.

Towards an Algorithmic Guide to Spiral Galaxies [PDF]

open access: yesTheoretical Computer Science, 2014
In this paper, we are interested in the one-player game Spiral Galaxies, and study it from an algorithmic viewpoint. Spiral Galaxies has been shown to be NP-hard [Friedman, 2002] more than a decade ago, but so far it seems that no one has dared exploring its algorithmic universe. We take this trip and visit some of its corners.

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

open access: yesAdvanced Robotics Research, Volume 2, Issue 5, October 2026.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.
