Visual imitation learning from one-shot demonstration for multi-step robot pick and place tasks

open access: yesScientific Reports
Imitation learning provides an intuitive approach for robot programming by enabling robots to learn directly from human demonstrations. While recent visual imitation learning methods have shown promise, they often depend on large datasets, which limits ...

Instability of composite beams in hogging bending [PDF]

open access: yes
This work is concerned with local buckling and lateral distortional buckling, two aspects of instability that govern the design of composite beams in hogging regions.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Shear strength and moment-shear interaction of steel-concrete composite beams:Experiments, numerical analyses, and design models

open access: yes, 2012
Current structural codes do not address the shear strength and the moment-shear interaction in composite beams explicitly. The shear is commonly assumed to be resisted by the steel beam alone neglecting the contributions of the slab and the composite ...

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Behaviour of composite beams under combined bending and tension

open access: yes, 2010
The results of an experimental programme on composite beams under combined bending and tension are presented in this paper. Results from this study extend previous work to form a completed interaction diagram for composite beams subjected to combined ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

A microscale modeling method for predicting the compressive behavior of 3D needled nonwoven fiber preforms

open access: yesMaterials & Design
The through-thickness compressive mechanism of 3D needled nonwoven fiber preforms is complicated due to the complex fiber structure and enormous fiber-to-fiber contacts.
