Defending Against Misuse of Synthetic Media: Characterizing Real-world Challenges and Building Robust Defenses
… models have enabled the generation of realistic synthetic media or deepfakes, including synthetic images, videos, and text. However, synthetic media can be misused for malicious purposes and damage users' trust in online content. This dissertation aims to address several key challenges in …

Investigating the use of synthetic media and real-time virtual camera filters for supporting communication and creativity
… Reality, little is known about the utility of synthetic media and real-time camera filters to reshape the perspective we have of ourselves and our capabilities. At the same time, the prevalence and popularity of these technologies have surged, coupled with greater usage of online communication …

The nature of serum agglutination of bovine spermatozoa: a proposed mode of action and its metabolic effects
… female genital fluids and other biological and synthetic media. Since semen is a colloid (undissolved particles suspended in a suitable medium such as gas, liquid, solid), spermatozoan agglutination should be at least partially definable by physical chemical measurements and should thereby be …

The growth of E. coli at various phosphate concentrations
… effects of phosphate on the bacterium E. coli in synthetic media. Growth was measured in batch and continuous flow cultures using both turbidimetric and respirometric techniques. The results obtained were used to formulate a hypothesis concerning the stimulation of algae by inorganic carbon …

The challenges of deepfake technology on the decision-making processes within law enforcement : a study within the EU landscape
… questionnaire distributed through intermediaries to law enforcement agencies across the EU, supplemented by secondary data and case studies to enhance validity through triangulation. Twelve officers responded (4 from Malta and 8 from other EU countries), all with direct or indirect …

Amino acid utilization by Aerobacter aerogenes and Escherichia coli
… on the growth of A. aerogenes and E. coli in synthetic media, but little work has been undertaken on the utilization by these organisms of amino acids as comparative sources of nitrogen. The most valuable study of this subject was made by Koser and Rettger in 1918, but it is incomplete due to …

Polyploidy in Saccharomyces cerevisiae leads to the loss of cell cycle control in stationary phase
… inviable after approximately 10-15 days in synthetic media. Analysis of the growth patterns of haploid and tetraploid cells during stationary phase reveals that tetraploids are defective for growth arrest during nutrient deprivation.

Viruses of Heliothis armigera (Hübner) (Lepidoptera : Noctuidae)
… propagated by passage in larvae reared on synthetic media. Pure CPV having been obtained, its replication and physico-chemical properties could be studied. Serological studies using immune electron microscopy and immune osmophoresis were used to detect and identify viruses of H. armigera …

Modification of Fermentation by Exogenous Energy Input
… diodes were employed to illuminate synthetic cultures under fermentation. Multiple colors along the visible spectrum were used, corresponding to the peak absorbance wavelengths of Saccharomyces sp. yeast. Impacts in primary metabolite evolution were found, dependent on wavelength. …

Environmental factor differences related to the growth of three species of Monoblepharella
… (1945) during the experiments was determined in synthetic media by means of dry weight measurements. All species were found to have optimum growth at 28 C with ranges extending somewhat higher than most water molds, The pH ranges from 4.5 to greater than 8 were similar to most aquatic fungi. …

Genes involved in thiol release from cysteine and glutathione conjugates by Saccharomyces cerevisiae during wine fermentation
… 4MMP from C-4MMP and 3MH from C-3MH and G-3MH in synthetic grape media. A wine yeast strain overexpressing IRC7F cleaved around 50% of C-4MMP and 10% of G-3MH into 4MMP and 3MH, respectively, in synthetic media. In addition, it was demonstrated that Irc7F cleaves L-cysteine in vitro (enzymatic …

Multimodal Foundation Models through the Lens of Security: Robust Deepfake Detection and Adversarial Resilience
… models can generate highly convincing deepfake media which can be misused to spread misinformation. This raises concerns about the authenticity of digital content and the potential for large-scale manipulation. To address this, it is crucial to develop robust detection methods that can …

Deciphering the contribution of root hairs in barley to the structure and function of the rhizosphere bacterial microbiota
… microbiota was constructed by isolating, on synthetic media, individual rhizosphere bacteria. A total of 85 isolates were further selected for full genome sequencing including members of the orders Actinomycetales, Flavobacteriales and Xanthomonadales. A comparative genomic approach was …
