Acknowledgements It is a pleasure to thank Jan Ambjrn for always inspiring and stimulating supervision and collaboration. I am also grateful for the valuable and fruitful collaboration that I have had with Jerzy Jurkiewicz and Yuri Makeenko as well as Zdzisek Burda and Leonid Chekhov. Finally the positive atmosphere and the support that I have experienced in the high energy theory group at NBI ...

To investigate whether low-level lighting is necessary and which narrow-band light spectra are effective in seeds germination, of 14 genotypes from begonia, echinacea, gerbera, petunia, vinca were germinated under ultraviolet-B (UVB), blue (B), green (G), red (R), far-red (FR) light, or darkness. Light-emitting diode (LED) fixtures provided all spectrum treatments except for UVB, was by a fluor...

This paper focuses on the problem of feature extraction and the classification of microvascular morphological types to aid esophageal cancer detection. We present a patch-based system with a hybrid SVM model with data augmentation for intraepithelial papillary capillary loop recognition. A greedy patch-generating algorithm and a specialized CNN named NBI-Net are designed to extract hierarchical...

This paper presents the first evidence of tetrachromacy among invertebrates. The Japanese yellow swallowtail butterfly, Papilio xuthus, uses colour vision when foraging. The retina of Papilio is furnished with eight varieties of spectral receptors of six classes that are the ultraviolet (UV), violet, blue (narrow-band and wide-band), green (single-peaked and double-peaked), red and broad-band c...

C l c3 Abstract-In this paper, a design method is described for low-sensitivity narrow-band band-pass switched-capacitor filters (SCF's) using a pseudo-2-path principle and a capacitor-error-free voltage inversion. The proposed method is based on the low-pass to high-pass transformation using voltage inversion, the pseudo2-path principle, the capacitance-ratio reduction technique and a very low...

Rotationally resolved fluorescence excitation spectra of the 0 band of the S 0 1←S0 transition of 1-methoxynaphthalene have been observed using a high resolution laser spectrometer operating in the ultraviolet. The trans-1-methoxynaphthalene band is an ab hybrid band with 38% a-type character and 62% b-type character. The band origin is at 31671.7 cm, and the rotational constants are A" = 1643....

The optical Einstein ring 0047 − 2808 was imaged by the VLT UT1 during the science verification programme. The ring is the image of a high–redshift z = 3.595 star– forming galaxy, with strong Lyα emission at 5589Å, gravita-tionally lensed by a massive early–type galaxy at z = 0.485. Relative to earlier NTT data the high signal–to–noise ratio of the VLT Lyα narrow–band image allows much improved...
