All-optical pulse retiming based on quadratic cascading in a periodically poled lithium niobate waveguide [PDF]
, 2010 We demonstrate an all-optical technique for the elimination of timing jitter in short pulse transmission systems. The technique relies on pulse pre-shaping followed by optical switching in a periodically poled lithium niobate waveguide via cascaded ...

The Soundscape of Man in the Holocene: An Exercise in Sensitization
Pulse, 2022 This paper discusses how the natural soundscape of Max Frisch’s novella Man in the Holocene (1979) affords a contemplation on the inadequacy of human epistemology against the immense temporality of the geological deep time.

A new pulse generator for pulsed ESR
Measurement Science and Technology, 1990 The construction of a new high-resolution multichannel low-cost pulse generator is reported. It is fully computer controlled through a simple RS232 serial interface. Its features are 1 ns resolution within any time, pulse delays up to 16 ms and pulse lengths up to 65 mu s, and pulse sequence repetition rate from 66 Hz up to 250 kHz.

Stringlike Pulse Quantification Study by Pulse Wave in 3D Pulse Mapping [PDF]
The Journal of Alternative and Complementary Medicine, 2012 A stringlike pulse is highly related to hypertension, and many classification approaches have been proposed in which the differentiation pulse wave (dPW) can effectively classify the stringlike pulse indicating hypertension. Unfortunately, the dPW method cannot distinguish the spring stringlike pulse from the stringlike pulse so labeled by physicians ...

Investigation of spectrally broad gain multiple-width quantum well material for colliding pulse mode-locked operation [PDF]
, 2004 The first colliding pulse mode-locked operation of devices fabricated from broad gain spectrum multiple-width quantum well material is reported. Using multiple-width quantum wells in the active region of the InGaAs/InAlGaAs material system, 35% broader ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Electrical engineering & Electromechanics, 2018 Purpose. A high-voltage underwater electric explosion, realized by discharging a capacitor into a water gap, is characterized by three main stages: the stage of formation of the plasma channel, the channel stage and post-discharge one. Substantially, the

Chirped-pulse amplification with narrowband pulses
Optics Letters, 2010 We demonstrate a compact hyperdispersion stretcher and compressor pair that permit chirped-pulse amplification in Nd:YAG. We generate 750 mJ, 0.2 nm FWHM, 10 Hz pulses recompressed to an 8 ps near-transform-limited duration. The dispersion-matched pulse compressor and stretcher impart a chirp of 7300 ps/nm, in a 3 m x 1 m footprint.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
