Single-stage few-cycle pulse amplification [PDF]
arXiv, 2023 Kerr instability can be exploited to amplify visible, near-, and mid-infrared ultrashort pulses. We use the results of Kerr instability amplification theory to inform our simulations amplifying few-cycle pulses. We show that the amplification angle-dependence is simplified to the phase matching condition of four-wave mixing when the intense pump is ...

Unfavorable Outcome of Neuroblastoma in Patients With 2p Gain
Frontiers in Oncology, 2019 Background: Amplification of the MYCN oncogene is the most unfavorable genetic factor in neuroblastoma patients. However, knowledge about the clinical impact of low-level multiplication of MYCN is still insufficient.

Neuroblastomas in Eastern China: a retrospective series study of 275 cases in a regional center [PDF]
PeerJ, 2018 Purpose Most studies on neuroblastoma (NB) have been conducted in Western countries or Japan. The objective of our study was to analyze clinical and pathological features, MYCN status, surgical methods, and prognosis in Chinese NB patients.

Deregulated enhancer‐promoter communication in cancer through altered nuclear architecture
International Journal of Cancer, EarlyView.Abstract Enhancers are critical regulators of gene expression. Structural variations in cancer genomes can lead to enhancer hijacking, where oncogenes are activated by mistargeted enhancer activity. Novel enhancer‐promoter interactions may also arise through chromosomal rearrangements that create extrachromosomal DNA elements.

Truly noiseless probabilistic amplification [PDF]
Vedran Dunjko and Erika Andersson, Truly noiseless probabilistic
amplification, Phys. Rev A 86, 042322 (2012), 2018 Most of the schemes for "noiseless" amplification of coherent states, which have recently been attracting theoretical and experimental interest, share a common trait: the amplification is not truly noiseless, or perfect, for non-zero success probability.

The relative contributions of genetic and non‐genetic factors to the risk of neuroblastoma
Pediatric Investigation, Volume 9, Issue 1, Page 82-93, March 2025.Germline variants, as well as copy number variations, confer increased risks of neuroblastoma (NB), often with effect estimates ≥ 1.5, underscoring the strong genetic contributions to NB. However, the strength of the association varies in non‐genetic factors.

Pediatric Investigation, EarlyView.Retinoma, a benign tumor caused by biallelic retinoblastoma gene (RB1) inactivation, offers key insights into retinoblastoma development and oncogenesis. This review explores its molecular genetics, clinical features, diagnosis, management, and potential implications for advancing the prevention and treatment of retinoblastoma.

Acquired Chromosomal Abnormalities and Their Potential Formation Mechanisms in Solid Tumours [PDF]
, 2017 Solid tumours include numerous malign or relatively less benign types of carcinomas and sarcomas. Acquired chromosomal abnormalities in solid tumours are hallmarks of gene deregulation and genome instability.

Optomechanical microwave amplification without mechanical amplification [PDF]
Phys. Rev. Applied 13, 014028 (2020), 2018 High-gain and low-noise signal amplification is a valuable tool in various cryogenic microwave experiments. A microwave optomechanical device, in which a vibrating capacitor modulates the frequency of a microwave cavity, is one technique that is able to amplify microwave signals with high gain and large dynamical range.
