PLM Reference Model: A Preliminary Proposal for Reference Model Evolution [PDF]

open access: yes, 2012
The adoption of product lifecycle management (PLM) business approach requires the implementation of PLM systems. Currently there is a wide variety of PLM systems in the market, but the scope differences between existing systems hamper the selection process for manufacturing companies.

Smooth toric varieties are Oka [PDF]

open access: yes, 2013
In this brief note, we show that every smooth toric variety over the field of complex numbers is an Oka manifold.Comment: Version 2: A remark corrected, a reference updated.

Pion scattering lengths from NA48

open access: yes, 2005
The anomaly (cusp) in the mass spectrum of two neutral pions from the three-pion decays of charged kaon has been observed in the NA48/2 experiment. Using the recently developed interpretation of this effect in terms of Chiral Perturbative Theory, the ...

Natural Products as Geroprotective Modulators in Diabetic Nephropathy: A Mechanistic Framework Integrating Aging Hallmarks and the AMPK–SIRT1–Nrf2 Axis

open access: yesAging and Cancer, EarlyView.
Natural products target the aging kidney in diabetic nephropathy by restoring the AMPK–SIRT1–Nrf2 axis, reducing oxidative stress, inflammation, fibrosis, and cellular senescence while enhancing mitochondrial biogenesis and antioxidant defenses.

The McCance Brain Care Score and Mortality: Evidence From a Large‐Scale Population‐Based Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives This study aimed to examine the relationship between the McCance Brain Care Score (BCS) and mortality in the general population. Methods We conducted a prospective, population‐based cohort study using data from the UK Biobank. Participants with complete data enabling calculation of BCS and full mortality information were included ...

Preliminary results from a simulation of quenched QCD with overlap fermions on a large lattice

open access: yes, 2003
We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at beta=6 on an 18^3x64 lattice. We calculate quark propagators for a single source point and quark mass ranging from am_q=0.03 to 0.75.
