Stellar collisions in galactic centers: black hole growth and color gradients [PDF]
, 2002 We study the effects of stellar collisions, particularly on feeding massive black holes (BHs) and color gradients, in realistic galactic centers. We find that the mass released by stellar collisions is not sufficient to account for the present BH mass in

The optical absorption of gamma irradiated and heat-treated natural quartz
Materials Research, 2005 Quartz with aluminum as impurity absorbs energy from ionizing radiation and modifies its color. Colorless quartz becomes smoky or dark smoky (morion quartz) when exposed to gamma rays.

Color centers in hexagonal boron nitride monolayers: A group theory and ab-initio analysis
, 2018 We theoretically study physical properties of the most promising color center candidates for the recently observed single-photon emissions in hexagonal boron nitride (h-BN) monolayers.

Clinical Course and Impact of Breaks in Therapy for Children With Relapsed/Refractory Solid Tumors
Pediatric Blood &Cancer, EarlyView.ABSTRACT Introduction Pediatric relapsed or refractory (R/R) solid tumors carry a dismal prognosis, and postrelapse patient experiences are not well described. We present postrelapse outcomes, including number of R/R events and subsequent therapy regimens.

Le Journal de Physique Colloques, 1973 Results of optical and EPR-experiments on color centers in additively and substractively colored SrCl2 single crystals are reported. In additively colored crystals F-centers could be obtained only after extremely rapid quenching. It was found that in crystals doped with O2- even with the very high quenching rate it was impossible to produce F-centers ...

Visible color-center laser in diamond [PDF]
Optics Letters, 1985 Laser action at 530 nm using H3 centers in diamond was observed with an efficiency of 13.5% at room temperature. Optical double-resonance experiments on N3 centers provided direct evidence for a (2)A metastable level. Its presence results in rapid decay of the excited (2)E state and low quantum efficiency as well as significant excited-state absorption

Implementing Health‐Related Quality of Life Assessment in Pediatric Oncology: A Feasibility Study
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background There is growing interest in embedding health‐related quality of life (HRQoL) assessment and patient‐reported outcome measures (PROMs) within clinical cancer care. This study evaluated the feasibility, acceptability, and usability of implementing an electronic PROM (ePROM) platform to measure HRQoL in children with cancer ...

Hybrid Group IV Nanophotonic Structures Incorporating Diamond Silicon-Vacancy Color Centers
, 2015 We demonstrate a new approach for engineering group IV semiconductor-based quantum photonic structures containing negatively charged silicon-vacancy (SiV$^-$) color centers in diamond as quantum emitters.

Rapid Response to Trametinib Combined With Chemotherapy for Infant BRAF‐Fused Chiasmatic Glioma
Pediatric Blood &Cancer, EarlyView.ABSTRACT Infants, less than 1 year, with chiasmatic gliomas (ICG) present a major therapeutic challenge due to large tumor size, decreased vision, rapid progression, and poor response to vincristine/carboplatin chemotherapy. The majority have a BRAF fusion, which may respond to downstream MEK inhibitors but response time is slow. There are no safety or
