Loops, Cutoffs and Anomalous Gauge Boson Couplings
, 1992 We discuss several issues regarding analyses which use loop calculations to put constraints on anomalous trilinear gauge boson couplings (TGC's). Many such analyses give far too stringent bounds.

Absolute Frequency Measurements of the Hg^+ and Ca Optical Clock Transitions with a Femtosecond Laser [PDF]
, 2001 The frequency comb created by a femtosecond mode-locked laser and a microstructured fiber is used to phase coherently measure the frequencies of both the Hg^+ and Ca optical standards with respect to the SI second as realized at NIST.

Winter Methane Fluxes Over Boreal and Arctic Environments
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract Unprecedented warming of Arctic–boreal regions (ABR) has poorly understood consequences on carbon cycle processes. Limited winter data add uncertainty to annual methane (CH4) budgets. In this study, winter CH4 flux measurements were conducted using the snowpack diffusion gradient method over five ABR ecosystem types in Canada and Finland ...

Making a Dynamic Interaction Between Two Power System Analysis Software
, 2017 This paper presents a distributed simulation based method for harmonic resonance assessment (HRA) in multi-area large-scale power systems. Further consideration is devoted to the early harmonic frequency-scan formulation to shape them into a Bordered ...

Off-diagonal hyperfine interaction between the 6p1/2 and 6p3/2 levels in 133Cs
, 2004 The off-diagonal hyperfine interaction between the 6p1/2 and 6p3/2 states in 133Cs is evaluated in third-order MBPT giving 37.3 Hz and 48.3 Hz, respectively, for second-order energies of the 6p3/2 F=3 and F=4 levels. This result is a factor of 10 smaller

, 2011 We have developed a technique to measure the absolute frequencies of optical transitions by using an evacuated Rb-stabilized ring-cavity resonator as a transfer cavity. We study possible wavelength-dependent errors due to dispersion at the cavity mirrors

Hydrogen Spectroscopy with a Lamb-shift Polarimeter - An Alternative Approach Towards Anti-Hydrogen Spectroscopy Experiments [PDF]
, 2010 A Lamb-shift polarimeter, which has been built for a fast determination of the polarization of protons and deuterons of an atomic-beam source and which is frequently used in the ANKE experiment at COSY-J\"ulich, is shown to be an excellent device for ...

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.ABSTRACT This experiment utilized oceanic mollusks, including Oliva sayana, Babylonia japonica, and Conasprella bermudensis, to synthesize hydroxyapatite (HAp). Orthophosphoric acid was reacted with the powdered components of marine mollusks, resulting in spherical and nanorod HAp.
