Class AB tunable active inductor

Electronics Letters, 2015
A class AB active inductor with high linearity, including a minimum number of components, is presented. Class AB operation is absent from the literature on the design of active inductors but is addressed in this reported work. Circuit details are given. A prototype board on a TLX8 substrate has been fabricated and tested showing the circuit feasibility

Autoantibody Profiles in Collagen Disease Patients with Interstitial Lung Disease (ILD): Antibodies to Major Histocompatibility Complex Class l-Related Chain a (MICA) as Markers of ILD

Biomarker Insights, 2015
Interstitial lung disease (ILD) is frequently associated with collagen disease. It is then designated as collagen vascular disease-associated ILD (CVD-ILD), and influences patients’ prognosis.

Comparative Assessment of Anti-HLA Antibodies Using Two Commercially Available Luminex-Based Assays

Transplantation Direct, 2017
Background. Allospecific anti-HLA antibodies (Abs) are associated with rejection of solid organ grafts. The 2 main kits to detect anti-HLA Ab in patient serum are commercialized by Immucor and One Lambda/ThermoFisher. We sought to compare the performance

Postoperative antibiotic treatment does not lower re-revision rate in presumed aseptic hip and knee revision arthroplasties with unexpected positive intraoperative cultures – a matched cohort study [PDF]

Journal of Bone and Joint Infection
Aims: It remains unclear if postoperative antibiotic (AB) treatment is advantageous in presumed aseptic revision arthroplasties of the hip (rTHA) and knee (rTKA) with unexpected positive intraoperative cultures (UPIC).

Covariant Wick rotation: action, entropy, and holonomies

European Physical Journal C: Particles and Fields, 2023
Given an arbitrary Lorentzian metric $$g_{ab}$$ g ab and a nowhere vanishing, timelike vector field $$u^a$$ u a , one can construct a class of metrics $${\widehat{g}}_{ab}$$ g ^ ab which have Euclidean signature in a specific domain, with a transition to

Measurement report: Size-resolved mass concentration of equivalent black carbon-containing particles larger than 700 nm and their role in radiation [PDF]

Atmospheric Chemistry and Physics, 2023
Black carbon (BC) mass size distribution (BCMSD) is crucial in both the environment and the climate system due to BC's intense size-dependent absorption of solar radiation.
