There is no water in the lake: synchronicity, metaphor, narrative, rhythm, and death, in fine art practice

This report comprises five dialogues that were converted into chapters and united into a single voice. Chapter one is about C.G. Jung’s theory of “synchronicity.” This term is defined, and the Tarkovsky film The Sacrifice is analyzed for its synchronistic merit. Historical notions of synchronicity and subsequent developments are mentioned, including reference to cosmology and quantum mechanics. The experience of synchronicity is numinous and examples are given from my studio practice. Some figures include Wilhelm, von Franz and Pauli. Ideas explored in subsequent chapters are rooted in this first chapter on synchronicity. Chance and fate are explored in my practice and final artworks often depict a landscape. Chapter two addresses this use of landscape while referencing film, poetry and photography. Romanticism, “the sublime,” and Japanese aesthetics, are all discussed in chapter two. Chapter three, on metaphor and image, draws from the philosophies of Paul Ricoeur and Gaston Bachelard, and references back to Jung and Tarkovsky. For example, “image” is more appropriate to my practice than “metaphor,” though “metaphor” heralds the expression of an “archetype” for Jung. Chapter four explores “rhythm” and my practice is seen as a continuum between word and image. Synchronistic moments suggest the absence of rhythm, and yet they also arrive rhythmically. Rhythmic “time compressions” and “time signatures” are examined. The rhythm of the circle is pondered upon; and this is related to the “monad” discussed in previous chapters. Studio-based experiments working with rhythm are outlined, including a performance of Joyce’s Portrait, as well as other studio-based projects working with verbal rhythms. The rhythms of grace, through the I Ching and St. Augustine’s Confessions, are also explored. This circumnavigation of rhythm culminates in the Jungian archetype of the Self, with many synchronistic consequences. The fifth and final chapter is about death and the photograph, and is designed around the following texts: Barthes, Camera Lucida; von Franz, On Dreams and Death; Whitman, Leaves of Grass; Langford, Suspended Conversations; Cousineau-Levine, Faking Death; Ritchie, A Tractate on Japanese Aesthetics; St. Augustine, Confessions. Nearly all of these texts use the “eidolon” to illustrate their ideas. Like a mystical garment, an archetypal image or eidolon suggests its form. Death and synchronicity are inextricably linked; and it is argued that photography is inherently metaphorical

On the implications of aerosol liquid water and phase separation for modeled organic aerosol mass

Water is an important component of PM2.5 Many traditional SOA species are highly soluble and thus can be considered extractable Water can influence the partitioning of compounds traditionally considered insoluble in models Organic aerosol takes up water according to RH Organic aerosol interacts with inorganic water Deviations in ideality (solubility) must be considered

Neural noise distorts perceived motion: the special case of the freezing illusion and the Pavard and Berthoz effect

When a slowly moving pattern is presented on a monitor which itself is moved, the pattern appears to freeze on the screen (Mesland and Wertheim in Vis Res 36(20):3325–3328, 1996) even if we move our head with the monitor, as with a head mounted display (Pavard and Berthoz in Perception 6:529–540, 1977). We present a simple model of these phenomena, which states that the perceived relative velocity between two stimuli (the pattern and the moving monitor) is proportional to the difference between the perceived velocities of these stimuli in space, minus a noise factor. The latter reflects the intrinsic noise in the neural signals that encode retinal image velocities. With noise levels derived from the literature the model fits empirical data well and also predicts strong distortions of visually perceived motion during vestibular stimulation, thus explaining both illusions as resulting from the same mechanism

Emissions of organic carbon and methane from petroleum and dairy operations in California's San Joaquin Valley

Petroleum and dairy operations are prominent sources of gas-phase organic compounds in California's San Joaquin Valley. It is essential to understand the emissions and air quality impacts of these relatively understudied sources, especially for oil/gas operations in light of increasing US production. Ground site measurements in Bakersfield and regional aircraft measurements of reactive gas-phase organic compounds and methane were part of the CalNex (California Research at the Nexus of Air Quality and Climate Change) project to determine the sources contributing to regional gas-phase organic carbon emissions. Using a combination of near-source and downwind data, we assess the composition and magnitude of emissions, and provide average source profiles. To examine the spatial distribution of emissions in the San Joaquin Valley, we developed a statistical modeling method using ground-based data and the FLEXPART-WRF transport and meteorological model. We present evidence for large sources of paraffinic hydrocarbons from petroleum operations and oxygenated compounds from dairy (and other cattle) operations. In addition to the small straight-chain alkanes typically associated with petroleum operations, we observed a wide range of branched and cyclic alkanes, most of which have limited previous in situ measurements or characterization in petroleum operation emissions. Observed dairy emissions were dominated by ethanol, methanol, acetic acid, and methane. Dairy operations were responsible for the vast majority of methane emissions in the San Joaquin Valley; observations of methane were well correlated with non-vehicular ethanol, and multiple assessments of the spatial distribution of emissions in the San Joaquin Valley highlight the dominance of dairy operations for methane emissions. The petroleum operations source profile was developed using the composition of non-methane hydrocarbons in unrefined natural gas associated with crude oil. The observed source profile is consistent with fugitive emissions of condensate during storage or processing of associated gas following extraction and methane separation. Aircraft observations of concentration hotspots near oil wells and dairies are consistent with the statistical source footprint determined via our FLEXPART-WRF-based modeling method and ground-based data. We quantitatively compared our observations at Bakersfield to the California Air Resources Board emission inventory and find consistency for relative emission rates of reactive organic gases between the aforementioned sources and motor vehicles in the region. We estimate that petroleum and dairy operations each comprised 22% of anthropogenic non-methane organic carbon at Bakersfield and were each responsible for 8-13% of potential precursors to ozone. Yet, their direct impacts as potential secondary organic aerosol (SOA) precursors were estimated to be minor for the source profiles observed in the San Joaquin Valley

Enhanced antipneumococcal antibody electrochemiluminescence assay: validation and bridging to the WHO reference ELISA

AIM: To re-optimize the pneumococcal (Pn) electrochemiluminescence (ECL) assay and to validate and bridge the enhanced assay to the WHO ELISA, to support the Phase III clinical trial program for V114, a 15-valent Pn conjugate vaccine. MATERIALS & METHODS: The Pn ECL assay was re-optimized, validated and formally bridged to the WHO ELISA. RESULTS: The enhanced Pn ECL assay met all prespecified validation acceptance criteria and demonstrated concordance with the WHO ELISA. The corresponding threshold value remains at 0.35 μg/ml for all 15 serotypes. CONCLUSION: The enhanced Pn ECL assay has been validated for the measurement of antibodies to 15 Pn capsular polysaccharides and is concordant with the WHO ELISA, supporting its use in clinical trials

A reconciliation of empirical and mechanistic models of the air-sea gas transfer velocity

Models of the air-sea transfer velocity of gases may be either empirical or mechanistic. Extrapolations of empirical models to an unmeasured gas or to another water temperature can be erroneous if the basis of that extrapolation is flawed. This issue is readily demonstrated for the most well-known empirical gas transfer velocity models where the influence of bubble-mediated transfer, which can vary between gases, is not explicitly accounted for. Mechanistic models are hindered by an incomplete knowledge of the mechanisms of air-sea gas transfer. We describe a hybrid model that incorporates a simple mechanistic view—strictly enforcing a distinction between direct and bubble-mediated transfer—but also uses parameterizations based on data from eddy flux measurements of dimethyl sulphide (DMS) to calibrate the model together with dual tracer results to evaluate the model. This model underpins simple algorithms that can be easily applied within schemes to calculate local, regional, or global air-sea fluxes of gases

High Resolution Spectroscopy of Two-Dimensional Electron Systems

Spectroscopic methods involving the sudden injection or ejection of electrons in materials are a powerful probe of electronic structure and interactions. These techniques, such as photoemission and tunneling, yield measurements of the "single particle" density of states (SPDOS) spectrum of a system. The SPDOS is proportional to the probability of successfully injecting or ejecting an electron in these experiments. It is equal to the number of electronic states in the system able to accept an injected electron as a function of its energy and is among the most fundamental and directly calculable quantities in theories of highly interacting systems. However, the two-dimensional electron system (2DES), host to remarkable correlated electron states such as the fractional quantum Hall effect, has proven difficult to probe spectroscopically. Here we present an improved version of time domain capacitance spectroscopy (TDCS) that now allows us to measure the SPDOS of a 2DES with unprecedented fidelity and resolution. Using TDCS, we perform measurements of a cold 2DES, providing the first direct measurements of the single-particle exchange-enhanced spin gap and single particle lifetimes in the quantum Hall system, as well as the first observations of exchange splitting of Landau levels not at the Fermi surface. The measurements reveal the difficult to reach and beautiful structure present in this highly correlated system far from the Fermi surface.Comment: There are formatting and minor textual differences between this version and the published version in Nature (follow the DOI link below
