Spinal Cord Stimulation as a Potential Therapeutic Modality for Managing Concurrent Chronic Low Back and Abdominal Pain Complicated by Device Migration: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT A 48‐year‐old man with chronic pancreatitis–related chronic abdominal pain (CAP) and concurrent chronic low back pain (LBP) with radiculopathy had inadequate relief from injectable and opioid therapies. A spinal cord stimulation (SCS) trial with dual leads spanning T4–T6 produced significant CAP relief, leading to permanent implantation at T5,

Assessment of competitiveness of power generating companies through a riskbased approach: a case study of developing economies [PDF]

open access: yes, 2016
The global financial crisis has shown that power companies are highly exposed to market risks. Market volatility creates competitive tension in the industry because the lack of the necessary methodological tools does not allow power companies to timely ...

Advances in Laser Powder Bed Fusion of Copper and Copper Alloys: Microstructure, Mechanical Behavior, and Conductivity

open access: yescMat, Volume 2, Issue 4, December 2025.
ABSTRACT Laser powder bed fusion (L‐PBF) has emerged as a complementary additive manufacturing (AM) technology and is capable of producing high‐resolution geometrically complex metal components. This review first highlights the role of minor copper (Cu) additions in refining microstructures and enhancing mechanical strength, corrosion resistance, and ...

Quasi-Stationary Strength of ECAP-Processed Cu-Zr at 0.5 Tm

open access: yesMetals, 2019
The influence of the grain structure on the tensile deformation strength is studied for precipitation-strengthened Cu-0.2%Zr at 673K. Subgrains and grains are formed by equal channel angular pressing (ECAP) and annealing.

Trapped charge dynamics in InAs nanowires

open access: yes, 2012
We study random telegraph noise in the conductance of InAs nanowire field-effect transistors due to single electron trapping in defects. The electron capture and emission times are measured as functions of temperature and gate voltage for individual ...
