    Interactive Sound Synthesis Mediated Through Computer Networks
    (eContact!, 1/08/2014) He J; Christopher K; Kapur A; Carnegie DA
    The digital age is continuously redefining the bounds of interaction. This has never been more apparent in the realm of sonic arts, where the idea of network interactivity is becoming increasingly ubiquitous. After all, art is essentially born of the interaction between people and the phenomenon around them. Interactivity is a fundamental element of music performance, whether it is amongst performers, the performers and the audience, or the performers and the work itself. Since the era of The League of Automatic Music Composers and The Hub (Gresham-Lancaster 1998), composers, musicians and music technologists have explored the paradigm of computer networks as the medium of interactivity in music systems (Barbosa 2003; Traub 2005; Mills 2010). Motivated in part by research into the microsonic components of sound creation, the authors introduce a method in which sound is generated by the feedback of an impulse across a network.

    Natural Variation in Chromium Accumulation and the Development of Related EST-SSR Molecular Markers in Miscanthus sinensis
    (MDPI (Basel, Switzerland), 2024-07-05) Nie G; Liu A; Ghanizadeh H; Wang Y; Tang M; He J; Feng G; Huang L; Zhang X; Tani E
    Soil pollution by heavy metals is a serious environmental concern globally. Hexavalent (VI) chromium (Cr) is one of the main pollutants causing groundwater and soil heavy metal pollution. Miscanthus sinensis is a C4 perennial grass species with a high level of heavy metal tolerance. This species can effectively remove Cr from soils and maintain desirable biomass production under Cr stress. This research aimed to characterize and compare Cr accumulation in 58 genotypes of M. sinensis and to develop Expressed Sequence Tagā€“Simple Sequence Repeat (EST-SSR) markers associated with Cr tolerance. The results show that the pattern of translocation of Cr in plants differed among the 58 M. sinensis genotypes following treatment of 200 mg/L of Cr6+; however, in most genotypes, the Cr was primarily accumulated in roots. A total of 43,367 EST-SSRs were identified, and 88 EST-SSR primer pairs corresponding to candidate genes involved in Cr accumulation in M. sinensis were selected for validation. Subsequently, 170 polymorphic loci generated from 24 validated EST-SSRs were used for the population structure and markerā€“trait association analysis. Based on a general linear model (GLM), a total of 46 associations were identified (p < 0.05), with 14 EST-SSRs markers associated with target traits. Among them, four genes related to ABC transporters, wall-associated receptor kinases, as well as two high-affinity sulfate transporters (ST), were identified under Cr stress (p < 0.05). The results of this study help to accelerate the screening across M. sinensis genotypes for desirable traits under Cr stress and provide a platform for M. sinensis genetic improvement and molecular-marker-assisted breeding.

    Parametrically-Dense Motion Sensing Devices and Robotic Musical Instruments
    (International Computer Music Association, 1/08/2016) He J; Murphy J; Kapur A; Carnegie DA
    The proliferation and ubiquity of sensor, actuator and microcontroller technology in recent years have propelled contemporary robotic musical instruments (RMIs) and digital music controllers to become more parametrically dense than their predecessors. Prior projects have focused on creating interaction strategies for relatively low degrees-of-freedom input and output schemes. Drawing upon prior research, this paper explores schemes for interaction between parametrically-dense motion-based control devices and contemporary parametrically-dense robotic musical instruments. The details of two interaction schemes are presented: those consisting of one-to-one control (allowing the actions of a performer to directly affect an instrument) and those consisting of a recognition system wherein user-created gestures result in output patterns from the robotic musical instrument. The implementation of the interaction schemes is described, and a performance utilizing these schemes is presented.

    Unique rumen micromorphology and microbiota-metabolite interactions: features and strategies for Tibetan sheep adaptation to the plateau.
    (Frontiers Media S.A., 2024-10-09) Chen Q; Sha Y; Liu X; He Y; Chen X; Yang W; Gao M; Huang W; Wang J; He J; Wang L; Zhang L
    The rumen microbiota-a symbiont to its host and consists of critical functional substances-plays a vital role in the animal body and represents a new perspective in the study of adaptive evolution in animals. This study used Slide Viewer slicing analysis system, gas chromatography, RT-qPCR and other technologies, as well as 16S and metabolomics determination methods, to measure and analyze the microstructure of rumen epithelium, rumen fermentation parameters, rumen transport genes, rumen microbiota and metabolites in Tibetan sheep and Hu sheep. The results indicate that the rumen nipple height and cuticle thickness of Tibetan sheep are significantly greater than those of Hu sheep (pā€‰<ā€‰0.01) and that the digestion and absorption of forage are greater. The levels of carbohydrate metabolism, lipid metabolism, and protein turnover were increased in Tibetan sheep, which enabled them to ferment efficiently, utilize forage, and absorb metabolic volatile fatty acids (VFAs). Tibetan sheep rumen metabolites are related to immune function and energy metabolism, which regulate rumen growth and development and gastrointestinal homeostasis. Thus, compared with Hu sheep, Tibetan sheep have more rumen papilla and cuticle corneum, and the synergistic effect of the microbiota and its metabolites is a characteristic and strategy for adapting to high-altitude environments.
