Spectral Shifts of Nonadiabatic High-Order Harmonic Generation
Applied Sciences, 2013 High-order harmonic generation (HHG) is a nonlinear nonperturbative process in ultrashort intense laser-matter interaction. It is the main source of coherent attosecond (1 as = 10−18 s) laser pulses to investigate ultrafast electron dynamics.

Signature of mass supply to quiet coronal loops [PDF]
Astron.Astrophys.478:915-919,2008, 2009 Aims. The physical implication of large blue shift of Ne viii in the quiet Sun region is investigated in this paper. Methods. We compare the significant Ne viii blue shifts, which are visible as large blue patches on the Doppler-shift map of a middlelatitude quiet-Sun region observed by SUMER, with the coronal magnetic-field structures as reconstructed

Self-frequency blue-shift of dissipative solitons in silicon based waveguides [PDF]
, 2013 We analyze the dynamics of dissipative solitons in silicon on insulator waveguides embedded in a gain medium. The optical propagation is modeled through a cubic Ginzburg-Landau equation for the field envelope coupled with an ordinary differential ...

SDSS J1619 with blue-shifted broad components in H$α$ and in [O~{\sc iii}] having similar line width and velocity shifts: a recoiling SMBH candidate? [PDF]
arXiv, 2023 In this Letter, we report a potential candidate of recoiling supermassive black hole (rSMBH) in SDSS J1619 based on similar velocity shifts and line widths of the blue-shifted broad components in H$\alpha$ and [O~{\sc iii}] doublet. The measured line width ratio between blue-shifted broad H$\alpha$ and broad [O~{\sc iii}] line is 1.06, if compared with

Sand-Dust Image Restoration Based on Reversing the Blue Channel Prior
IEEE Photonics Journal, 2020 Images acquired under sand-dust weather conditions are severely degraded, with low contrast and severe color shift. The reason is that, due to the influence of sand-dust particles, light is scattered and absorbed, resulting in a blurred image and low ...

Old, New, Borrowed and Blue – Shifts In Modern Policing
The British Journal of Criminology, 2021 AbstractThis article analyses ambiguity and complexity in proactive policing practices and identifies the paradox that despite the focus on increasing proactivity, police work remains strongly reactive. Drawing on a set of Norwegian case studies of policing in different domains, the article shows how under an overarching objective of ‘combating crime’,

Improving Peak-Wavelength Method to Measure Junction Temperature by Dual-Wavelength LEDs
IEEE Access, 2017 In this paper, the improvement of the method measuring the junction temperature of lightemitting diodes (LEDs) has been studied experimentally. A practical method is proposed with only three measurement procedures.

Anomalous blue-shift of terahertz whispering-gallery modes via dielectric and metallic tuning [PDF]
, 2019 The vast majority of resonant systems show a red-shift for the resonance frequency when a perturbation, e.g. losses, are introduced to the system. In contrast, here we report for the first time the experimental demonstration of both red- and anomalous blue-shifting of whispering-gallery modes (WGMs) using dielectric and metallic substrates. The maximum
