  abstract     = {{<jats:p>Several recent proposals in integrated photonics concern components that operate on so-called semi-guided waves. Given a dielectric multilayer slab structure, these are wave solutions that propagate along the slab with the functional dependence of ordinary harmonic plane waves, but with modal confinement in the direction perpendicular to the slab plane. While the in-plane unbounded waves are valid as a theoretical construct, practical devices will have to work with laterally confined optical fields. To that end we consider Gaussian superpositions of semi-guided waves, for a range of in-plane propagation angles, here named “semi-guided Gaussian beams.” This paper collects a series of relations that characterize these wave bundles, with emphasis on their divergence. The expressions resemble standard results for optical Gaussian beams, with modifications originating from the 1-D guiding and 1-D bundling. Examples for a high-contrast silicon-on-insulator slab at a typical telecom wavelength are discussed.</jats:p>}},

  abstract     = {{Janus metasurfaces have attracted considerable attention in encrypted communication, imaging, and display due to their unusual bidirectional asymmetric optical manipulation characteristics. Particularly, their multifunctionalization is of great significance for enhancing the compactness and integration of optical systems. However, the realization of multifunctional Janus metasurfaces in the optical band still faces enormous difficulties and challenges, which are essentially limited by the anti-error design and processing methods of multi-layer cascade metasurfaces. Here, a triple-layer Janus metasurface based on cascaded plasmonic nano-antenna arrays fully buried in SiO2 is constructed. Among them, the cascaded plasma nano-antenna consists of two types of enantiomers for each wavelength. Each enantiomer is fabricated with two layers of L-shaped nanostructures with phase modulation and one layer of dimer nanostructures with polarization selection stacked alternately along the optical axis. We experimentally show that the Janus metasurface achieves bidirectional asymmetric multi-channel holographic encryption, simultaneously using propagation direction, phase, polarization, and wavelength for the first time in the near-infrared band, which is expected to provide a frontier route for multifunctional optical displays, high-level optical information encryption, and large-capacity full-duplex communication.}},

                  <jats:p>Distinct neural correlates are associated with the processing of augmented feedback during motor learning. To examine the basic neural response of delayed augmented feedback, 33 participants practiced a right-arm flexion-extension-movement performed with an arm-lever-device in 192 trials with subsequent feedback presentation. The movement sequence consisted of three movement reversals, which were practiced with the goal of minimizing errors in spatial accuracy. Based on a performance-adaptive bandwidth for spatial movement accuracy, participants received delayed augmented feedback indicating whether they had achieved one predefined reversal (of the three), or not. The feedback delay duration alternated block-wise between 1500 ms and 7000 ms. EEG was recorded throughout practice. The error-related negativity (ERN) and the error positivity (Pe) are assumed to reflect neural error processing in a predictive manner based on intrinsic information, whereas the feedback-related negativity (FRN) is assumed to reflect neural error processing in a postdictive manner based on extrinsic outcome feedback. It was hypothesized that the ERN and the Pe would be more pronounced in trials with longer feedback delays, which unfortunately could not be tested. The relevant components were not detected in the signal, possibly due to the complex sequential structure of the task and the feedback pattern. With respect to feedback valence, results regarding the FRN were as expected. Further, the results demonstrate a more pronounced neural processing of augmented feedback with respect to a shorter feedback delay duration. These results indicate that delaying augmented feedback impacts the neural processing of augmented feedback in motor practice.</jats:p>}},

  abstract     = {{We revisit the under-explored phenomenon of syntactic complexity convergence in dialogue. Extending prior topic-level analyses to full conversations, we examine five human-human datasets and a set of human-LLM dialogues. We integrate and evaluate a multidimensional set of syntactic complexity metrics to quantify structural variation in dialogue. Our analyses reveal robust syntactic complexity convergence across human-human datasets, especially in task-oriented interactions, and statistical tests confirm that these effects are not due to chance. In contrast, human-LLM dialogues show no significant convergence under individual metrics; however, linear-CKA uncovers a distinct cross-metric convergence pattern. Motivated by these differences, we use syntactic complexity as a feature for detecting LLM-involved dialogue, achieving 96\% accuracy. Our classification results demonstrate its potential without relying on likelihood-based signals such as surprisal, which require a language model as the estimator.}},

  abstract     = {{This study examines the impact of tax certainty through advance tax rulings (ATRs) on firms’ risky investments under cash flow and tax uncertainty. Both firms and governments have expressed growing concern about increasing tax uncertainty, due to frequent tax reforms and the difficulty in applying ambiguous tax laws and anticipating audit outcomes. One remedy is the provision of ATRs, which offer upfront clarification of tax issues to reduce tax uncertainty and increase risk-taking. We analyze how these uncertainties, along with different tax rates, loss offset provisions, and ATR fees affect investment strategies. Our results suggest, first, that ATRs encourage riskier investments, particularly in tax regimes with generous loss offsets. We identify optimal ranges of ATR fees that benefit firms and tax authorities. Second, we show that it may be beneficial to design ATRs with a low or negative fee. Third, our study reveals a U-shaped relationship between firms’ risk aversion and their willingness to pay for tax certainty, with willingness being higher for firms at low or high levels of risk aversion. In contrast, moderately risk-averse firms are only willing to accept low fees. Overall, our results highlight the importance of low-cost tax certainty combined with generous loss offset provisions to encourage risky investments.}},
