Derivation of myoepithelial progenitor cells from bipotent mammary stem/progenitor cells.
PLoS ONE, 2012 There is increasing evidence that breast and other cancers originate from and are maintained by a small fraction of stem/progenitor cells with self-renewal properties.

The band-edge excitons observed in few-layer NiPS3
npj 2D Materials and Applications, 2021 Band-edge excitons of few-layer nickel phosphorous trisulfide (NiPS3) are characterized via micro-thermal-modulated reflectance (μTR) measurements from 10 to 300 K. Prominent μTR features of the A exciton series and B are simultaneously detected near the

Electronics Letters, 1977 Single-stage f.e.t. amplifiers operating in K-band have been constructed using the Varian VSX 9305 0.5 µm-gate GaAs f.e.t. An amplifier gain of 9±1 dB was obtained over the frequency band 18.5-20.5 GHz and gain of 8±1 dB was observed from 23.0 to 26.0 GHz. An amplifier noise figure of 5.6 dB was measured at 24 GHz.

The “H and K” Bands of Carbon [PDF]
Nature, 1926 IN discussing the negative bands of carbon, Deslandres mentions (Comptes rendus, 137, p. 460, 1903) the two strong bands λ2883.86 and 2897.11 which “are very intense, are diffuse on both sides, are of a different structure and otherwise very curious”, and suggests that they may probably be due to oxygen.

Design of a curved， band-pass frequency selective surface radome with steep cut-off performance
Dianzi Jishu YingyongThe traditional frequency selective surface（FSS）radome has the problem such as high structural profile and insufficient out of band cut-off performance. A design method for low-profile and band-pass FSS radome with steep out of band cut-off in K-band is ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with acute lymphoblastic leukemia (ALL) are at risk of severe outcomes from SARS‐CoV‐2 (SCV2). In the post‐pandemic context, where most children have been infected with SCV2, there are limited data on whether vaccination remains beneficial in children with ALL.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background An internal tandem duplication in the gene encoding Fms‐like tyrosine kinase 3 (FLT3‐ITD) is associated with high relapse risk and poor prognosis in acute myeloid leukemia (AML) and plays a crucial role in treatment decisions. Measurable residual disease (MRD) analysis of FLT3‐ITD during and after treatment has shown prognostic ...
