First detection of CF+ towards a high-mass protostar [PDF]

open access: yes, 2015
We report the first detection of the J = 1 - 0 (102.6 GHz) rotational lines of CF+ (fluoromethylidynium ion) towards CygX-N63, a young and massive protostar of the Cygnus X region.

The role of TRECs/KRECs as immune indicators that reflect immunophenotypes and predict the risk of infection in systemic autoimmune diseases

open access: yesImmunological Medicine
T cell receptor rearrangement excision circles (TRECs) and immunoglobulin κ-deleting recombination excision circles (KRECs) represent the lymphopoiesis capacity, widely used for newborn screening of inborn errors of immunity.

Bimolecular recombination reactions: K-adiabatic and K-active forms of the bimolecular master equations and analytic solutions [PDF]

open access: yes, 2016
Expressions for a K-adiabatic master equation for a bimolecular recombination rate constant k_(rec) are derived for a bimolecular reaction forming a complex with a single well or complexes with multiple well, where K is the component of the total angular

Newborn screening for severe combined immunodeficiency: The results of the first pilot TREC and KREC study in Ukraine with involving of 10,350 neonates

open access: yesFrontiers in Immunology, 2022
Severe combined immunodeficiency (SCID) is a group of inborn errors of immunity (IEI) characterized by severe T- and/or B-lymphopenia. At birth, there are usually no clinical signs of the disease, but in the first year of life, often in the first months ...

Dilution Effect for High‐Performance Multiple‐Component Near‐Infrared Organic Photodetectors

open access: yesAdvanced Science, EarlyView.
The dilution effect in multi‐component organic photodetector effectively suppresses non‐radiative decay and minimizes dark current, while energy‐level‐offset‐governed electron transfer between acceptors maintains efficient charge transport. This synergistic mechanism collectively enables remarkable device performance, including high detectivity and ...

DETERMINING REFERENCE RANGES FOR TREC AND KREC ASSAYS IN IMMUNE DEFICIENCY SCREENING OF NEWBORNS IN RUSSIAN FEDERATION

open access: yesМедицинская иммунология, 2019
In this work, we used a reference population of newborns and sampled dried blood spots on Guthrie cards of 2,739 individual samples to determine the reference intervals for TRECs and KRECs values, in order to diagnose primary immunodeficiency by means of

Clinical and Genetic Study of X-linked Agammaglobulinemia Patients (The Benefit of Early Diagnosis)

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2020
X-linked agammaglobulinemia (XLA) is a primary immunodeficiency caused by genetic defects in the Bruton tyrosine kinase (Btk) gene. XLA is characterized as an antibody deficiency by recurrent bacterial infections, the absence of peripheral B cells, and ...

Tunable source of correlated atom beams

open access: yes, 2013
We use a one-dimensional optical lattice to modify the dispersion relation of atomic matter waves. Four-wave mixing in this situation produces atom pairs in two well defined beams.

Feasibility Study and Optimal Placement of Solar Power Plants Using Binary Genetic Algorithm

open access: yesEnergy Science &Engineering, EarlyView.
This study introduces an integrated optimization framework using a binary genetic algorithm (BGA) for optimal siting and sizing of two solar plants (865 and 739 kWp) in Karaj, Iran. The BGA outperformed conventional methods, achieving a 24.3% reduction in power losses and enhanced voltage stability.
