Operational results with fast automatic beam-based LHC collimator alignment [PDF]

open access: yes, 2013
The CERN Large Hadron Collider (LHC) is the largest and highest-energy particle accelerator ever built. It is designed to collide particles at a centre-of-mass energy of 14 TeV to explore the fundamental forces and constituents of matter.

L-Shape Propagated Array Configuration With Dynamic Reconfiguration Algorithm for Enhancing Energy Conversion Rate of Partial Shaded Photovoltaic Systems

open access: yesIEEE Access, 2021
Partial shading is an unavoidable factor that reduces the performance of solar PV systems. The PV system receives uneven irradiation due to partial shading which causes the mismatch loss.

Power Enhancement in Partial Shaded Photovoltaic System Using Spiral Pattern Array Configuration Scheme

open access: yesIEEE Access, 2021
Partial shading causes mismatch losses in the solar PV system. In the PV array, the power output from the healthy PV modules is gone in vain due to the mismatch losses.

Detrimental Effect of Low-Magnitude High-Frequency Vibration in an Ex Vivo Model of Intervertebral Disc Degeneration Despite Estrogen Treatment. [PDF]

open access: yesJOR Spine
Low‐magnitude high‐frequency vibration (LMHFV), with or without 17β‐oestradiol (E2), exacerbated papain‐induced bovine intervertebral disc degeneration, reducing cell viability, impairing matrix production, and increasing inflammation. E2 showed no protective effect against papain‐induced degeneration or LMHFV.

Markov basis and Groebner basis of Segre-Veronese configuration for testing independence in group-wise selections

open access: yes, 2007
We consider testing independence in group-wise selections with some restrictions on combinations of choices. We present models for frequency data of selections for which it is easy to perform conditional tests by Markov chain Monte Carlo (MCMC) methods ...
