Target and double spin asymmetries of deeply virtual π0 production with a longitudinally polarized proton target and CLAS

open access: yesPhysics Letters B, 2017
The target and double spin asymmetries of the exclusive pseudoscalar channel e→p→→epπ0 were measured for the first time in the deep-inelastic regime using a longitudinally polarized 5.9 GeV electron beam and a longitudinally polarized proton target at ...

Gluon skewed generalized parton distributions of proton from a light-front Hamiltonian approach

open access: yesPhysics Letters B
We calculate all leading-twist gluon generalized parton distributions (GPDs) inside the proton at nonzero skewness using the basis light-front quantization framework.

Transverse spin effects and holography

open access: yesEPJ Web of Conferences, 2015
The holographic sum rules for GPDs and the appearance of holographic variables in the TMD models are discussed. The relation between GPDs and TMDs in the spirit of Veneziano duality is suggested.

Off-line Handwritten Signature GPDS-960 Corpus

open access: yes, 2007
The current need for large databases to evaluate automatic biometric recognition systems has motivated the developing of the GPDS-960 corpus, an off-line handwritten signature database which contains 24 genuine signatures and 30 forgeries of 960 ...

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Generalized parton distributions of pion for non-zero skewness in AdS/QCD

open access: yesNuclear Physics B, 2018
We study the generalized parton distributions (GPDs) of pion for non-zero skewness by considering the leading |qq¯〉 Fock state component. Inspired from AdS/QCD light-front wave functions, we calculate the pion GPDs.
