Synthetic Social Media Data Generation

IEEE Transactions on Computational Social Systems, 2018
This paper presents a novel system, synthetic high-fidelity social media data generator (SHIELD), for generating the synthetic social media data. SHIELD jointly generates time-varying, directed and weighted interaction graph structures and topic-driven text features similar to the input social media data. A synthetic interaction graph is generated by a

Synthetic seismograms in attenuating media

GEOPHYSICS, 1983
Synthetic seismograms are computed in a two‐dimensional medium that contains contrasts both in the elastic and in the attenuation (Q) properties with depth. The case of a liquid‐solid interface, with and without a Q contrast between the two media, is examined in detail.

Advanced synthetic ferrimagnetic media (invited)

Journal of Applied Physics, 2002
The exchange coupling field (Hex) in two-layer synthetic ferrimagnetic media (SFM) is enhanced to extend the areal density capability of earlier structures. The thermal stability of SFM is improved by employing high magnetic anisotropy stabilizing layers without significantly affecting the required write fields.

Extracts of molds grown on synthetic media

Journal of Allergy, 1949
Abstract 1.1. A method is described for preparing mold extracts which eliminates the use of peptone in media. 2.2. Mold extracts thus prepared are more potent than the former extract of the same protein nitrogen unit value. 3.3. These mold extracts prepared by the synthetic media were apparently not irritating. 4.4.

Synthetic filter media: Balancing energy efficiency and electrostatics in new synthetic filter media

Filtration & Separation, 2011
Pushing back the influence of electrostatics on filter media while operating in an energy efficient manner is a major goal in air filtration. Dr. Andreas Seeberger of IREMA FILTER GmbH describes some recent developments.

Penicillin-induced spheroplast formation in synthetic media

Biochemical Pharmacology, 1962
Abstract The induction of spheroplasts of Escherichia coli by treatment of the organism with penicillin in a simple, chemically defined medium is described, and is shown to depend on the available concentration of Mg 2+ ions, on the temperature of incubation, and on the stage of growth of the bacterial cells when penicillin is added.

Synthetic aperture sonar in turbulent media

The Journal of the Acoustical Society of America, 1979
A method of synthetic aperture sonar imaging that is effective even in turbulent media is proposed. Signals received at a fixed point on a scanning plane are used as reference signals, and the averaging effect is applied in the process of aperture synthesis to obtain stable images within the same scanning time as conventional methods. The principle and

Deepfakes and Synthetic Media

Deepfakes and synthetic media, powered by AI technologies like Generative Adversarial Networks (GANs) and Diffusion Models, pose significant threats to digital trust and security. These tools enable the creation of highly realistic forgeries, which are increasingly exploited in social engineering attacks to spread misinformation, manipulate emotions ...

Synthetic Radical Reactions in Aqueous Media

Synlett, 2002
This account focuses on the discovery and the rationalization of solvent effects, especially those of water, on synthetically useful radical reactions. Noteworthy advantages were observed during the course of our study onradical reactions in aqueous media.
