Hard- and soft-fermion-pole contributions to single transverse-spin asymmetry for Drell-Yan process

open access: yes, 2011
We study the single transverse-spin asymmetry for the Drell-Yan lepton pair production based on the twist-3 mechanism in the collinear factorization. We calculate all the hard-pole (HP) and the soft-fermion-pole (SFP) contributions to the single-spin ...

Relationship of structure and stiffness in laminated bamboo composites [PDF]

open access: yes, 2018
Laminated bamboo in structural applications has the potential to change the way buildings are constructed. The fibrous microstructure of bamboo can be modelled as a fibre-reinforced composite.

Plywood Cantilever Deflection: Experimental, Analytical and FEM Approach

open access: yesDrvna Industrija, 2023
In this paper, the elastic behaviour in bending of three-layer plywood cantilever beams is analysed. Deflections of straight and half-circle cantilevers, loaded with a force at free end is determined experimentally and calculated using analytical and ...

Cross sectional imaging is transforming the diagnosis of rare congenital defects

open access: yesEuropean Heart Journal, 2021
Abstract Aim Partial anomalous pulmonary venous connection (PAPVC) is a rare congenital anomaly in which at least one of the pulmonary veins do not drain into the left atrium. Patients with PAPVC can often be asymptomatic and the presence of right heart dilatation on echo should prompt assessment of ...

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Formation mechanism of defects in the wall of a petroleum casing steel pipe

open access: yes工程科学学报, 2022
In this study, the defects in the wall of petroleum casing steel pipe were investigated. The morphology and composition of inclusions in the defects of the steel pipe were analyzed using scanning electron microscopy–energy-dispersive X-ray spectroscopy ...

Scattering cross-section of a transformation optics-based metamaterial cloak

open access: yesNew Journal of Physics, 2010
We present experimental quantitative scattering cross-section (SCS) measurements for a metamaterial cloak. The cloak is nearly identical to that reported in 2006; however, quantitative experimental measurements have not yet been reported for such a structure.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in
