Compensation of Kerr nonlinearity-induced distortions has been shown to allow for increasing transmission rate and reach, with optical compensation techniques particularly attractive broadband wavelength-division multiplexed (WDM) scenarios. However, they normally require additional devices within the link, which is challenging already deployed systems, even more so unrepeatered transmission. I...

We show that 4-dimensional conjugation manifolds are all obtained from branched 2-fold coverings of knotted surfaces in Z2-homology 4-spheres.

She notices the formal similarity between the stem tuk‘attachINTRANS’ in (1a) and tuke‘attachTRANS’ in (1b). These two represent the two main verb conjugations in Japanese: tukrepresents the consonant stem or godan conjugation, while tukerepresents the vowel stem or ichidan conjugation. The learner also notices the grammatical relationship between the two stems: tukis the intransitive and tuket...

Antisense oligonucleotides (ASOs) conjugated to triantennary N-acetyl galactosamine (GalNAc) ligands represent an emerging approach to antisense therapy. Our current generation of GalNAc-ASO conjugates link the GalNAc to the 5'-terminus of the ASO. The conjugation reaction can be accomplished using solution-phase or solid-phase techniques. Here we show a direct comparison of a solution-phase an...

We study the symmetry behavior of the Gross-Neveu model in three and two dimensions with random chemical potential. This is equivalent to a fourfermion model with charge conjugation symmetry as well as Z2 chiral symmetry. At high temperature the Z2 chiral symmetry is always restored. In three dimensions the initially broken charge conjugation symmetry is not restored at high temperature, irresp...

We introduce a new method for reducing phase noise in oscillators, thereby improving their frequency precision. The noise reduction is realized by a passive device consisting of a pair of coupled nonlinear resonating elements that are driven parametrically by the output of a conventional oscillator at a frequency close to the sum of the linear mode frequencies. Above the threshold for parametri...

Thyristor rectifiers are widely used in electric railways in order to control the speed. As a consequence of their usage in addition to substantial input lead current, an enormous amount of harmonics is injected into the grid. To avoid such harmonics as well as reactive power compensation, reactive power hybrid filters consisting of active and passive filters are utilized. Regarding different p...
