Hazard Assessment of Germanium Supplements
, 1997 Germanium-containing dietary supplements became popular in the 1970s in Japan and later in other countries, as elixirs for certain diseases (e.g., cancer and AIDS). Germanium is not an essential element. Its acute toxicity is low.

Arthritis Care &Research, EarlyView.Objective We aimed to validate the Pediatric Arthritis Ultrasound Scoring System (PAUSS) for upper extremity joints in children with juvenile idiopathic arthritis (JIA). Methods Children with JIA were evaluated for elbow, wrist, or finger arthritis by clinical examination (CE) and musculoskeletal ultrasound (MSUS) with images scored according to the ...

Structural study of Germanium (11) phthalocyanine
, 1971 Germanium(ll)phthalocyanine forms crystals belonging to space group P2/c with a=27.11, sigma=0.012 Å, b=10.39, sigma=0.020 Å, c=21.96, sigma=0.014 Å, beta=107.86, sigma-0.0680. There are eight molecules per unit cell.Patterson maps show that the molecule

Arthritis Care &Research, EarlyView.Objective To explore whether higher body fat and lower lean mass are associated with greater pain and worse patient‐reported physical function in individuals with hip osteoarthritis (OA). A secondary aim was to examine whether pain and patient‐reported physical function differ according to four body composition profiles: high body fat, low lean mass ...

Reverse graded high content (x>0.75) Si1-xGex virtual substrates [PDF]
Silicon germanium alloy layers can be grown epitaxially on a silicon substrate to provide a means of adjusting the lattice parameter of the crystal. Such a platform, known as a virtual substrate, has a number of potential applications.

Phosphorous clustering in germanium-rich silicon germanium
, 2008 The formation of clusters consisting of donor atoms and lattice vacancies can deleteriously affect the performance of silicon germanium devices. In the present study results from electronic structure calculations are evaluated using mass action analysis ...

Arthritis Care &Research, EarlyView.Objective The concern that nonsteroidal anti‐inflammatory drugs (NSAIDs) may precipitate flares of inflammatory bowel disease (IBD) has limited their use in managing musculoskeletal symptoms in those with IBD, but safety data are mixed. Methods This retrospective cohort study included patients with IBD aged at least 18 years from Optum's deidentified ...

Calibration of germanium resistors at low temperatures (2-20 Kelvin)
, 1966 Two germanium resistors, C and D, have been referenced to values of temperature determined by the NBS acoustical thermometer. The resistance-temperature calibration data for these resistors have been fitted to a function of the form [equation not ...

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.
