Size of precipitation pulses controls nitrogen transformation and losses in an arid Patagonian ecosystem
(Springer, 2010-05)
Arid ecosystems receive precipitation pulses of different sizes that may differentially affect nitrogen (N) losses and N turnover during the growing season. We designed a rainfall manipulation experiment in the Patagonian ...
Transform-limited pulses generated by an actively Q-switched distributed fiber laser
(Optical Society of America, 2008-11-15)
A single-mode, transform-limited, actively Q-switched distributed-feedback fiber laser is presented, based on a new in-line acoustic pulse generator. Our technique permits a continuous adjustment of the repetition rate ...
Evaluation of DC-AC single-phase solid-state transformers
(Institute of Electrical and Electronics Engineers, 2019-11-02)
This work presents an evaluation of three topologies of DC-AC single-phase solid-state transformers, for applications in electric microgrids. The main features of these topologies are galvanic isolation, capability to ...
Refractive index calculation from echo interference in pulsed terahertz spectroscopy
(Inst Engineering Technology-iet, 2014-02)
A method for calculating the average refractive index of a sample using transmission terahertz time-domain spectroscopy in a single measurement is presented. The refractive index is derived from the analysis of the ...
Characteristics of the extreme events observed in the Kerr-lens mode-locked Ti:sapphire laser
(American Physical Society, 2015-01)
Kerr-lens mode-locked Ti:sapphire lasers are known to display three coexistent modes of operation: continuous wave, transform limited pulses (P1), and positive chirped pulses (P2). Extreme events (sometimes also called ...
Magnon squeezing in an antiferromagnet: Reducing the spin noise below the standard quantum limit
(American Physical Society, 2004-09)
The quantum squeezing of a collective spin-wave excitation (magnon) was investigated using femtosecond optical pulses. The quantum squeezed magnon was used to generate correlations involving pairs of spins in an antiferromagnetic ...
Pulse compression hardware decoding techniques for MST radars
(American Geophysical Union, 1985-11)
The techniques for decoding in hardware received signals transmitted by phase‐coded mesosphere‐stratosphere‐troposphere (MST) radars are reviewed. The designs consist of digital and analog types which resemble filters or ...
Large amplitude noise reduction in ultrashort pulse trains using a power-symmetric nonlinear optical loop mirror
