Advanced configuration of gravitational-wave interferometer on the base of "sensitive mode" in "white-light cavity"
A novel conception of "sensitive mode" (SM) is proposed to apply in
gravitational-wave advanced interferometer configuration. The SM is resonant
oscillation of electromagnetic field in "white-light cavity", where the
resonance line is broadened without decreasing cavity quality. The frequency of
the SM is greatly susceptible to the change of cavity length, and the SM is
established in a cavity with time constant smaller than a conventional mode.
Due to these advantages the sensitivity and bandwidth of AIC can be increased.Comment: 9 pages, 5 figure
The nuclear collective motion
Current developments in nuclear structure are discussed from a theoretical perspective. First, the progress in theoretical modeling of nuclei is reviewed. This is followed by the discussion of nuclear time scales, nuclear collective modes, and nuclear deformations. Some perspectives on nuclear structure research far from stability are given. Finally, interdisciplinary aspects of the nuclear many-body problem are outlined

Interindividual size heteromorphism of NOR and chromosomal location of 5S rRNA genes in Iheringichthys labrosus
Twenty-five specimens of Iheringichthys labrosus from the Capivara Reservoir were analysed cytogenetically. AgNORs were detected in a pair of ST chromosomes, in the telomeric region of the long arm. Some individuals showed size heteromorphism of this region between homologous chromosomes. Treatment with CMA3 displayed GC-rich regions corresponding to the AgNOR pair, plus other fluorescent staining. In situ hybridization by fluorescence (FISH) with the 18S rDNA probe showed only one pair of stained chromosomes, confirming the heteromorphism observed with AgNO3 and CMA3 in some individuals. The 5S rDNA probe revealed telomeric staining on the long arm of a pair of chromosomes of the ST-A group, probably different from the NOR pair.<br>Foram analisados citogeneticamente vinte e cinco indivíduos de Iheringichthys labrosus da Represa Capivara. As AgNORs foram detectadas em um par de cromossomos ST na região telomérica do braço longo. Em alguns exemplares machos e fêmeas foi observado um heteromorfismo de tamanho desta região entre cromossomos homólogos. O tratamento com CMA3 exibiu regiões ricas em GC correspondentes ao par da NOR e outras marcações fluorescentes. A hibridação in situ por fluorescência (FISH) com a sonda de DNAr 18S mostrou somente um par de cromossomos marcados, confirmando o heteromorfismo observado com AgNO3 and CMA3 em alguns indivíduos. A sonda de DNAr 5S revelou marcação telomérica no braço longo de um par de cromossomos do grupo ST-A, provavelmente diferente do par da NOR
