Summary: In this study, we investigated a non-interacting ?/V-type dice model composed of three triangular sublattices. By considering various nearest-neighbor and next-nearest-neighbor hoppings with phase, as well as quasi-staggered on-site potential, we obtained full phase diagrams under different fillings of the energy bands. The system exhibits abundant topological non-trivial phases with different Chern numbers, as well as a metal phase in several regimes, and the bulk-edge correspondence was confirmed by analyzing the edge-state energy spectrum.

Summary: One-shot face reenactment is addressed in this paper by proposing a novel and interpretable framework based on spatial-temporal reconstruction views. The framework achieves precise transfer of facial expressions and intuitive control over the generated images by using the 3D Morphable Face Model (3DMM) as an immediate representation. Experimental results demonstrate the effectiveness of the framework in improving the robustness of motion reconstruction, especially for large-scale head movements.

Summary: In this paper, we propose an end-to-end network to reconstruct high-resolution images from low-resolution spike streams. Our network adopts a multi-level features learning mechanism, including intra-stream feature extraction, inter-stream dependencies extraction, and joint features learning. Experimental results demonstrate that our network is superior to the combination of state-of-the-art intensity image reconstruction methods and super-resolution networks on simulated and real datasets.

Summary: Understanding the temporal stability of associations between crash characteristics at different temporal levels is crucial for developing effective traffic safety policies. This study uses multiple correspondence analysis to investigate these associations. The findings suggest that associations between crash characteristics show cyclical variations at lower temporal levels, but become more stable and long-term as the temporal level increases, particularly at the two-year level and higher. This study highlights the challenge of interpreting associations between crash characteristics when considering different temporal levels, and provides a foundation for further research and practical applications in traffic safety.

Summary: Recent studies have achieved remarkable success in image animation using deep generative models. However, previous methods synthesize animation results frame by frame, leading to flickering and inconsistent output. In this paper, we propose a novel self-supervised framework that processes a video clip directly to maintain coherence in the animated video. By leveraging temporal information, a spatial-temporal correspondence network is designed to propagate keypoints between adjacent frames, ensuring consistency. Additionally, a 3D-CNN-based generator and discriminator are applied to ensure coherence in the final output video. Extensive experiments on benchmark datasets demonstrate the effectiveness of the proposed method.

Summary: An appealing strategy for reconstructing paleoenvironmental change is to linearly interpolate between marker beds of known age. However, changes in sedimentary processes can invalidate this method and affect estimates of time from the strata. When sedimentary processes change, measuring time linearly systematically overestimates time duration and misestimates the beginning and end of geologic intervals. Geologic evidence for changes in sediment dispersal can help identify sections of dilated and shifted time, and better resolve time in sedimentary strata.

Summary: In this work, a scalable integrated spectrometer is proposed and demonstrated, achieving ultrahigh resolution and improved channel capacity. The spectrometer is based on a spatially reconfigurable multimode cavity formed by a waveguide array and delay lines, with enhanced mode mixing and random temporal speckles. Any arbitrary input spectrum can be computationally retrieved from the recorded output signal.

Summary: This paper introduces a correspondence imaging approach for reconstructing high-quality objects through complex scattering media. By deriving a rectified theory and introducing temporal correction, the proposed method eliminates the effect of dynamic scaling factors. Experimental results demonstrate the advantages of the proposed method over conventional methods in complex scattering environments, and it can also be combined with other methods to further enhance the quality of reconstructed objects.

Summary: This paper proposes a novel particle method for establishing dense shape correspondence between pre- and post-surgical surfaces in temporal lobe resection. The method can handle partial structural abnormality involving non-rigid changes. Unlike existing particle methods, explicit particle adjacency is considered to establish a smooth correspondence. Moreover, hierarchical optimization of particles is proposed to avoid the trappings of locally optimal particle update.

Summary: Introns, which make up only a quarter of the human genome, host about 60% of all known microRNAs. The co-regulation of intronic microRNAs with their host genes plays a crucial role in cancer, yet their significance in cancer pathogenesis is often underestimated.

Summary: This paper demonstrates both theoretically and experimentally that the synergy of chirality and anisotropy can produce three different directional dipoles in one structure. By selecting different faces, selective manipulation of optical directionality can be achieved. This structure enables high-dimensional control of both near-field and far-field directionality, with broad applications in various fields such as photonic integrated circuits, quantum information processing, and subwavelength-resolution imaging.

Summary: The PTB's bistatic lidar, with three dedicated receivers arranged around a central transmitter, achieves independent measurements of all three wind velocity components with high spatial and temporal resolution. It can serve as a transfer standard for the calibration of other remote sensing devices, enhancing the capability and accuracy of wind velocity measurements.

Summary: In this study, we theoretically investigate the thermoelectric properties of the Dice lattice and compare them with graphene. We focus on the role of the flat band and find that the Dice lattice exhibits additional pairs of thermopower peaks near the band center compared to graphene, due to the presence of the flat band. In the high temperature regime, the emergent thermopower peaks show unconventional dependence on temperature and disorder, contrary to the Mott's relation, which is attributed to the extremely narrow bandwidth of the broadened flat band. We also discuss the enhancement of thermopower by introducing an energy gap in the Dice lattice.

Summary: This study reports a noninvasive method for gastrointestinal tract imaging based on lanthanide-doped nanocrystals in the near-infrared-IIb window. The rational design of the nanocrystals resulted in high quantum yield and improved spatial resolution by minimizing scattering. The method also achieved high temporal resolution and three-dimensional imaging, and successfully diagnosed inflammatory bowel disease.
