The study investigates two different ways of guiding the addressee of an explanation - an explainee, through action demonstration: contrastive and non-contrastive. Their effect was tested on attention to specific action elements (goal) as well as on event memory. In an eye-tracking experiment, participants were shown different motion videos that were either contrastive or non-contrastive with respect to the segments of movement presentation. Given that everyday action demonstration is often multimodal, the stimuli were created with re- spect to their visual and verbal presentation. For visual presentation, a video combined two movements in a contrastive (e.g., Up-motion following a Down-motion) or non-contrastive way (e.g., two Up-motions following each other). For verbal presentation, each video was combined with a sequence of instruction descriptions in the form of negative (i.e., contrastive) or assertive (i.e., non-contrastive) guidance. It was found that a) attention to the event goal increased for this condition in the later time window, and b) participants’ recall of the event was facilitated when a visually contrastive motion was combined with a verbal contrast.

In this work, we find that in a liquid crystal (LC) microcavity filled with perovskite microplates, the pronounced TE-TM splitting gives rise to a strong SOC that leads to the spatial instability of microcavity polariton condensates under single-shot excitation. Spatially varying hole burning and mode competition occurs between polarization components leading to different condensate profiles from shot to shot. The single-shot polariton condensates become stable when the SOC vanishes as the TE and TM modes are spectrally well separated from each other, which can be achieved by application of an electric field to our LC microcavity with electrically tunable anisotropy. Our findings are well reproduced and traced back to their physical origin by our detailed numerical simulations. With the electrical manipulation our work reveals how the shot-to-shot spatial instability of spatial polariton profiles can be engineered in anisotropic microcavities at room temperature, which will benefit the development of stable polariton-based optoeletronic and light-emitting devices. author: - first_name: Ying full_name: Gao, Ying last_name: Gao - first_name: Xuekai full_name: Ma, Xuekai last_name: Ma - first_name: Xiaokun full_name: Zhai, Xiaokun last_name: Zhai - first_name: Chunzi full_name: Xing, Chunzi last_name: Xing - first_name: Meini full_name: Gao, Meini last_name: Gao - first_name: Haitao full_name: Dai, Haitao last_name: Dai - first_name: Hao full_name: Wu, Hao last_name: Wu - first_name: Tong full_name: Liu, Tong last_name: Liu - first_name: Yuan full_name: Ren, Yuan last_name: Ren - first_name: Xiao full_name: Wang, Xiao last_name: Wang - first_name: Anlian full_name: Pan, Anlian last_name: Pan - first_name: Wei full_name: Hu, Wei last_name: Hu - first_name: Stefan full_name: Schumacher, Stefan last_name: Schumacher - first_name: Tingge full_name: Gao, Tingge last_name: Gao citation: ama: Gao Y, Ma X, Zhai X, et al.

Here, we demonstrate the control of an artificial Rashba-Dresselhaus (RD) SOC mediated by photochemical reactions in a microcavity filled with an organic single-crystal of photochromic phase-change character. Splitting of the circular polarization components of the optical modes induced by photonic RD SOC is observed experimentally in momentum space. By applying an ultraviolet light beam, we control the spatial molecular orientation through a photochemical reaction and with that we control the energies of the photonic modes. This way we realize a reversible conversion of spin-splitting of the optical modes with different energies, leading to an optically controlled switching between circularly and linearly polarized emission from our device. Our strategy of in situ and reversible engineering of SOC induced by a light field provides a promising approach to actively design and manipulate synthetic gauge fields towards future on-chip integration in photonics and topological photonic devices. author: - first_name: Qian full_name: Liang, Qian last_name: Liang - first_name: Xuekai full_name: Ma, Xuekai last_name: Ma - first_name: Jiahuan full_name: Ren, Jiahuan last_name: Ren - first_name: Teng full_name: Long, Teng last_name: Long - first_name: Chunling full_name: Gu, Chunling last_name: Gu - first_name: Cunbin full_name: An, Cunbin last_name: An - first_name: Hongbing full_name: Fu, Hongbing last_name: Fu - first_name: Stefan full_name: Schumacher, Stefan last_name: Schumacher - first_name: Qing full_name: Liao, Qing last_name: Liao citation: ama: Liang Q, Ma X, Ren J, et al.

Here we theoretically demonstrate the realization of EPs in a system with significant nonlinearity, a non-equilibrium exciton-polariton condensate. With the possibility to control loss and gain and nonlinearity by optical means, this system allows for a comprehensive analysis of the interplay of nonlinearities (Kerr-type and saturable gain) and non-Hermiticity. Not only do we find that EPs can be intentionally shifted in parameter space by the saturable gain, we also observe intriguing rotations and intersections of Riemann surfaces, and find nonlinearity-enhanced sensing capabilities. Our results are quite general in nature and illustrate the potential of tailoring spectral topology and related phenomena in non-Hermitian systems by nonlinearity. author: - first_name: Jan full_name: Wingenbach, Jan last_name: Wingenbach - first_name: Stefan full_name: Schumacher, Stefan last_name: Schumacher - first_name: Xuekai full_name: Ma, Xuekai last_name: Ma citation: ama: Wingenbach J, Schumacher S, Ma X.

When they do, they must\r\nprotect this collected data according to the current legal frameworks. Such\r\ndata protection has become even more important since the European Union rolled\r\nout the General Data Protection Regulation (GDPR). App developers have limited\r\ntool support to reason about data protection throughout their app development\r\nprocess. Although many Android applications state a privacy policy, privacy\r\npolicy compliance checks are currently manual, expensive, and prone to error.\r\nOne of the major challenges in privacy audits is the significant gap between\r\nlegal privacy statements (in English text) and technical measures that Android\r\napps use to protect their user's privacy. In this thesis, we will explore to\r\nwhat extent we can use static analysis to answer important questions regarding\r\ndata protection. Our main goal is to design a tool based approach that aids app\r\ndevelopers and auditors in ensuring data protection in Android applications,\r\nbased on automated static program analysis." author: - first_name: Mugdha full_name: Khedkar, Mugdha id: '88024' last_name: Khedkar citation: ama: 'Khedkar M.
