The Satanic Whitman: Woman, Nature and the Magic of Four

Had the Romantics lived in the twentieth-century and maintained their Romantic sensibility, they might have been Jungians, which is to say, there are a considerable number of parallels between Jungian theory and Romantic aesthetics. According to Jung the aim of all psychoanalytic work is to help the analysand become conscious of his or her entire Self, which includes conscious as well as disowned, unconscious elements. In Jungian theory when ego (conscious awareness) confronts and assimilates shadow (unconsciousness), the result is a revitalization and expansion of Self. Romantics longed for this expanded Self in their frequent transcendent yearnings, concerned as they were with the aspects of being denied by Enlightenment. I have discussed this urge to reject Enlightenment modes of ideation and being in favor of a more subversive, mystical orientation in several recent articles and a book, Mystical Discourse as Ideological Resistance in Wordsworth and Whitman. Romanticism entailed the reappropriation of marginalized, subjugated modes of being. All historical periods and artistic schools, according to Morris Philipson, were tendencies of art which brought to the surface that unconscious element of which the contemporary atmosphere had most need (in Snider, 2). Psychologically speaking, then, Romanticism was to Enlightenment what the Renaissance was to the Dark Ages--its repressed other, its shadow. Romanticism provided late eighteenth- and nineteenth century aesthetic consciousness with what it lacked--a chance to engage its other self and assimilate repressed energies into a new mode of aesthetic creation

Constraints on Mars Aphelion Cloud Belt Phase Function and Ice Crystal Geometries

This study constrains the lower bound of the scattering phase function of Martian water ice clouds (WICs) through the implementation of a new observation aboard the Mars Science Laboratory (MSL). The Phase Function Sky Survey (PFSS) was a multiple pointing all-sky observation taken with the navigation cameras (Navcam) aboard MSL. The PFSS was executed 35 times during the Aphelion Cloud Belt (ACB) season of Mars Year 34 over a solar longitude range of L_s=61.4{\deg}-156.5{\deg}. Twenty observations occurred in the morning hours between 06:00 and 09:30 LTST, and 15 runs occurred in the evening hours between 14:30 and 18:00 LTST, with an operationally required 2.5 hour gap on either side of local noon due the sun being located near zenith. The resultant WIC phase function was derived over an observed scattering angle range of 18.3{\deg} to 152.61{\deg}, normalized, and compared with 9 modeled phase functions: seven ice crystal habits and two Martian WIC phase functions currently being implemented in models. Through statistical chi-squared probability tests, the five most probable ice crystal geometries observed in the ACB WICs were aggregates, hexagonal solid columns, hollow columns, plates, and bullet rosettes with p-values greater than or equal to 0.60, 0.57,0.56,0.56, and 0.55, respectively. Droxtals and spheres had p-values of 0.35, and 0.2, making them less probable components of Martian WICs, but still statistically possible ones. Having a better understanding of the ice crystal habit and phase function of Martian water ice clouds directly benefits Martian climate models which currently assume spherical and cylindrical particles.Comment: Accepted Manuscript by Planetary and Space Scienc

Imaginary Squashing Mode Spectroscopy of Helium Three B

We have made precision measurements of the frequency of a collective mode of the superfluid 3He-B order parameter, the J=2- imaginary squashing mode. Measurements were performed at multiple pressures using interference of transverse sound in an acoustic cavity. Transverse waves propagate in the vicinity of this order parameter mode owing to off-resonant coupling. At the crossing of the sound mode and the order parameter mode, the sound wave is strongly attenuated. We use both velocity and attenuation measurements to determine precise values of the mode frequency with a resolution between 0.1% and 0.25%.Comment: 6 pages, 4 figures, submitted to proceedings of Quantum Fluids and Solids (QFS) Conference 2006; revised 9/26/0

Parametrically controlling solitary wave dynamics in modified Kortweg-de Vries equation

We demonstrate the control of solitary wave dynamics of modified Kortweg-de Vries (MKdV) equation through the temporal variations of the distributed coefficients. This is explicated through exact cnoidal wave and localized soliton solutions of the MKdV equation with variable coefficients. The solitons can be accelerated and their propagation can be manipulated by suitable variations of the above parameters. In sharp contrast with nonlinear Schr\"{o}dinger equation, the soliton amplitude and widths are time independent.Comment: 4 pages, 5 eps figure

The Laser Communications Relay Demonstration Experiment Program

This paper elaborates on the Laser Communications Relay Demonstration (LCRD) Experiment Program, which will engage in a number of pre-determined experiments and also call upon a wide variety of experimenters to test new laser communications technology and techniques, and to gather valuable data. LCRD is a joint project between NASA's Goddard Space Flight Center (GSFC), the Jet Propulsion Laboratory (JPL), and the Massachusetts Institute of Technology Lincoln Laboratory (MIT LL). LCRD will test the functionality in various settings and scenarios of optical communications links from a GEO (Geosynchronous Earth Orbit) payload to ground stations in Southern California and Hawaii over a two-year period following launch in 2019. The LCRD investigator team will execute numerous experiments to test critical aspects of laser communications activities over real links and systems, collecting data on the effects of atmospheric turbulence and weather on performance and communications availability. LCRD will also incorporate emulations of target scenarios, including direct-to-Earth (DTE) links from user spacecraft and optical relay providers supporting user spacecraft. To supplement and expand upon the results of these experiments, the project also includes a Guest Experimenters Program, which encourages individuals and groups from government agencies, academia and industry to propose diverse experiment ideas

DM2 platform II : AI-assisted optimization of oral solid dosage form development

Digital Medicines Manufacturing (DM2) platform II aims to leverage AI to develop an autonomous workflow for drug product manufacturing and testing system by identifying optimal formulation and process parameters that deliver desired critical quality attributes (CQAs). This approach aims to de-risk and accelerate drug product development by reducing experiments, development time, and materials use by 60%. The initial objective is to develop a database of hundreds of historical data and new experiments. This database is then used to develop a hybrid machine for predicting product (tablets and capsules) attributes by utilizing domain knowledge (empirical/mechanistic models) and AI-powered models (where domain knowledge is not available/reliable). The hybrid machine is then integrated into an iterative, model-informed optimization framework, to smartly plan experiments that drive the automated manufacturing and testing system, which will be used to collect multi-scale and –point data and update the model(s) to learn from the experiments. Fit-for-purpose optimization algorithms will be employed to execute this loop based on the objective of experiments (i.e. exploration of the knowledge space or exploitation of the model-based optimization) and it continues until the targets are achieved. The proposed smart experimental planning method has been tested using the Gurnham (empirical) model as a predictor of porosity based on peak compression pressure. The initial analysis of the uncertainty of fit demonstrates that adding only 1 data point results in a 20-fold improvement in the accuracy of prediction while adding 8 more data points leads to a minimal improvement, highlighting the significance of the here-developed smart experimental planning procedure in achieving acceptable prediction accuracy at a minimal experimentation cost

Affordances-in-practice:an ethnographic critique of social media logic and context collapse

Drawing on data gathered during ethnographic fieldwork in Mardin, a medium-sized town in southeast Turkey, this article shows that social media users actively appropriate online platforms and change privacy settings in order to keep different social spheres and social groups apart. Keeping different online social contexts distinct from each other is taken for granted as a way of using social media in Mardin. By contrast, social media scholars have extensively discussed the effects of social media in terms of context collapse. The article highlights how context collapse is the result of patterns of usage within Anglo-American contexts and not the consequence of a platform's architecture or social media logic. It then suggests a theoretical refinement of affordances, and proposes the concept of affordances-in-practice

S-, P- and D-wave resonances in positronium-sodium and positronium-potassium scattering

Scattering of positronium (Ps) by sodium and potassium atoms has been investigated employing a three-Ps-state coupled-channel model with Ps(1s,2s,2p) states using a time-reversal-symmetric regularized electron-exchange model potential fitted to reproduce accurate theoretical results for PsNa and PsK binding energies. We find a narrow S-wave singlet resonance at 4.58 eV of width 0.002 eV in the Ps-Na system and at 4.77 eV of width 0.003 eV in the Ps-K system. Singlet P-wave resonances in both systems are found at 5.07 eV of width 0.3 eV. Singlet D-wave structures are found at 5.3 eV in both systems. We also report results for elastic and Ps-excitation cross sections for Ps scattering by Na and K.Comment: 9 pages, 5 figures, Accepted in Journal of Physics

Controlling pulse propagation in optical fibers through nonlinearity and dispersion management

In case of the nonlinear Schr\"odinger equation with designed group velocity dispersion, variable nonlinearity and gain/loss; we analytically demonstrate the phenomenon of chirp reversal crucial for pulse reproduction. Two different scenarios are exhibited, where the pulses experience identical dispersion profiles, but show entirely different propagation behavior. Exact expressions for dynamical quasi-solitons and soliton bound-states relevant for fiber communication are also exhibited.Comment: 4 pages, 5 eps figure
