In this research, an attempt to obtain a bright superchiral lattice is made by superposing four laser beams in a particular configuration. Additionally, this superposition should theoretically lead to homogeneous electric fields without modulation, which is potentially useful in microscopy. Recording the field with a simple CMOS camera and observing its fast Fourier transform gives rise to aliasing effects due to undersampling caused by the fact that interference occurs at a subpixel level. This phenomenon is investigated by numeric and analytic simulations. By rotation of the camera, pixel superresolution was achieved, which effectively enables the possibility to investigate the interference patterns at a subpixel level and hence measure the angle between pair of beams with good accuracy. With newly developed beam alignment methods we have achieved and confirmed a beam alignment that is sufficient for production of bright superchirality lattices.Show less

Although at first glance, it appears like bots make up a substantial amount of their followers, compared to other established media, their number is not significant, but rather a representation of the overall inauthentic bot population on the SMP. Among the inspected outlets, only the Italian outlet “ilGiornale” exhibited abnormal metrics throughout all steps of the analysis and is therefore considered to benefit from CP methods. Since this RNQ has not uploaded any content to Instagram since May 2019 and only has 16 posts in total, an increased exposure to their content is considered to be no threat to democratic deliberation. Rather, even without CP, it is an emerging right-wing media ecosystem that poses an increasing challenge to EU democracy. These findings, however, should be taken cautiously, as in the course of the empirical chapter, it becomes obvious that qualitative bot-detection models were designed for Twitter or Facebook and do not adequately take the platform-specifics of Instagram into account. Hence, the number of bots and subsequently the number of RNQ accounts that benefit from CP might actually be higher than this analysis suggests.Show less

In a small-scale experiment, Arabic speakers of English were asked to translate an Arabic story to English by hand to create an authentic product of their spelling abilities. Afterwards, the same participants read a short story in English, which was recorded with audio equipment to later evaluate their pronunciation through the program PRAAT. Contrary to existing literature, the small-scale experiment conducted for this study found no significant effect for the influence of Arabic on English spelling despite this being hypothesised and proven in previous research. Along with this, no effect was found for the experiment based on the pronunciation of /p/ and /v/. Whereas the results did show that Arabic speakers of English had a Voice Onset Time (VOT) of /p/ that was considerably lower, they did not realise a [b] instead of the target [ph] as hypothesised. Speakers did not significantly devoice their /v/ to an [f], which does not directly coincide with the literature that has hypothesised the influence of native language phonology on the pronunciation of English as a second language. When evaluating the results as a whole, two things are implied: (1) there is a possible focus in ESL learning on spelling and therefore no issues were found, and (2) pronunciation is a difficult aspect of ESL learning due to the unfamiliar articulatory processes involved and Arabic learners experience difficulties when faced with the unfamiliar /p/ and to a lesser degree also /v/. However, they are able to make the distinction between the phoneme pairs. These implications may help ESL learners in the future to focus on problem areas, further improve their skills, while simultaneously providing the research niche of phonology with new material to investigate.Show less
