    Notes: A computer simulation study of a two-dimensional two-component resistor network model is presented. The model is constructed to elucidate the relationship between interfacial dynamics and formation of porous structures. The interfacial dynamics, which are stochastic in nature, have been studied and the effect of both global and regional characteristics in interfacial dynamics on the resulting morphologies has been investigated. In the simulation, the advancing interface exhibits either an unstable front as dictated by the Mullins–Sekerka instability, or a stable one that is roughened by kinetic noise. The relevance of the simulation to the experimental observations of porous silicon formation is demonstrated and the implications are discussed.

    Notes: In the classical q-deformed oscillators system, the Poisson bracket realizations of the quantum enveloping algebras of An−1 and Cn types are given in the symplectic space (V,Ω) (without deformation). When the oscillators system is canonically quantized, the Lie bracket realizations of the quantum enveloping algebras of An−1 and Cn types are obtained. The Hopf structures of these quantum enveloping algebras are supplied.

    Notes: Summary Auditory sensitivity was determined for the oscar, Astronotus ocellatus, a cichlid fish that has no known structural specializations to enhance hearing. Trained A. ocellatus behaviorally responded to sound stimuli from 200 Hz to 800 Hz with best sensitivity of 18 dB (re: 1 μbar) to 21 dB for frequencies between 200 and 400 Hz. This is significantly poorer than hearing sensitivity for fish classified as hearing specialists, but well within the range of hearing capabilities reported for non-specialist teleost species.

    Notes: Abstract An elliptic deformation of $$\widehat{s1}_2 $$ is proposed. Our presentation of the algebra is based on the relationRLL = LLR *, whereR andR * are eight-vertexR-matrices with the elliptic moduli chosen differently. In the trigonometric limit, this algebra reduces to a quotient of that proposed by Reshetikhin and Semenov-Tian-Shansky. Conjectures concerning highest-weight modules and vertex operators are formulated, and the physical interpretation ofR * is discussed.

    Notes: Summary 1. Sternopygus macrurus were collected in Venezuela during the period of gonadal recrudescence in early or late dry season. Electric organ discharge (EOD) frequencies were recorded, blood samples were taken for analysis of steroid titers, and gonads were taken for determination of reproductive condition. 2. Mean EOD frequencies were significantly lower in males than in females in all samples. EOD frequency was inversely correlated with body length in males in late, but not early, dry season, and these parameters were never correlated in females. 3. Plasma levels of testosterone (T) and 11-ketotestosterone (11-KT), but not estradiol-17β (E2), were inversely correlated with EOD frequency in males. No 11-KT was observed in plasma of females, and plasma levels of T and E2 in females were comparable to those of males. Neither T nor E2 were correlated with EOD frequency in females. 4. Testes collected in late dry season were more mature than those from early dry season; androgen levels and EOD frequency were correlated with testicular maturity. Ovaries collected in early dry season were immature, while those from late dry season were more mature. There was no relationship between EOD frequency and stage of ovarian development. 5. These results suggest that plasma androgens modulate EOD frequency in males during the reproductive season and that plasma E2 has little relationship to EOD frequency in either sex.

    Notes: Abstract Spatial variation in photosynthetic photon flux density (PPFD) was investigated in detail at different heights within the canopy of aMiscanthus sinensis grassland to evaluate the light environment of microsites for establishment of heliophilic tree seedlings. Highly heterogeneous patterns of light distribution were revealed within the apparently uniform grass canopies, especially under direct light. The frequency distribution patterns of relative PPFD (RPFD) were compared among different solar and sky conditions. With increasing height in the canopy, the mean RPFD value and standard deviation (SD) increased, while the skewness and kurtosis of the distribution decreased. The mean RPFD and SD were higher, especially at higher solar elevation angles, under direct light than those under diffuse light conditions. The frequency distribution of RPFD was more platykurtic under direct light and at higher solar elevation angles.

    Notes: Abstract An allele of the Drosophila melanogaster alcoholdehydrogenase (Adh) gene has a 1.15-kb KP elementinserted, in the same orientation as Adh transcription,five nucleotides upstream of the distal transcription start site. The target site-GTCCAAGT — inAdh between nucleotides –13 and –6 isduplicated at both ends of the insertion. Adult flieswith either one or two copies of the allele have lessthan 12% of the alcohol dehydrogenase (ADH) activity of thecontrols. Activity levels are also reduced in larvae,but by a much smaller amount. Quantitative Northernanalyses showed that the low activity level in adults was caused by reduced transcript levels fromthe distal promoter. 5′ RACE experiments indicatedthat adult transcripts were mostly initiated downstreamof the distal promoter but some skipped the first adult exon. In late third-instar larvae thetranscripts present were from the proximal promoter.After the KP element was deleted by an appropriatebreeding program, the distal transcript increased inadults to the control level, but ADH activityincreased to only 50% of the control. No nucleotidechanges were found in the gene that could explain thisdifference.
