Article Synopsis
- Spintronic terahertz emitters (STEs) are powerful terahertz sources that can operate across a wide range of pumping frequencies, yet their performance is ultimately limited by their optical damage threshold.
- Recent advancements in technology require STEs to pump at higher megahertz rates rather than the traditional kilohertz rates, highlighting a gap in research on this topic.
- The study introduces a new classification of the optical damage threshold based on repetition rates and identifies temperature-driven inter-layer diffusion as the main failure cause, offering insights for improving STE performance in future applications.
Spintronic terahertz emitters promise terahertz sources with an unmatched broad frequency bandwidth that are easy to fabricate and operate, and therefore easy to scale at low cost. However, current experiments and proofs of concept rely on free-space ultrafast pump lasers and rather complex benchtop setups. This contrasts with the requirements of widespread industrial applications, where robust, compact, and safe designs are needed.

View Article and Find Full Text PDFA four-month-old boy with primary immunodeficiency was found to have a homozygous germ-line mutation of the gene encoding the CD3zeta subunit of the T-cell receptor-CD3 complex. CD3zeta is necessary for the development and function of T cells. Some of the patient's T cells had low levels of the T-cell receptor-CD3 complex and carried the Q70X mutation in both alleles of CD3zeta, whereas other T cells had normal levels of the complex and bore the Q70X mutation on only one allele of CD3zeta, plus one of three heterozygous somatic mutations of CD3zeta on the other allele, allowing expression of poorly functional T-cell receptor-CD3 complexes.
View Article and Find Full Text PDFBackground: Impaired Fas-induced apoptosis of lymphocytes in vitro is a principal feature of the autoimmune lymphoproliferative syndrome (ALPS). We studied six children with ALPS whose lymphocytes had normal sensitivity to Fas-induced apoptosis in vitro.
Methods: Susceptibility to Fas-mediated apoptosis and the Fas gene were analyzed in purified subgroups of T cells and other mononuclear cells from six patients with ALPS type III.
