The Mongolian University of Science and Technology (MUST; Mongolian: Шинжлэх Ухаан, Технологийн Их Сургууль) was founded in 1959 as a part of the National University of Mongolia and started training the Industrial Economics and Construction Engineers. As a result of the formation of engineering and technical teaching staff, in 1969 the National University of Mongolia was affiliated the Polytechnic Institute with five schools such as: Civil Engineering, Power Engineering, Geology and Mining, Mechanical Engineering, and Engineering Economics had established with 13 departments. In 1982, by the decision of the Council of Ministers of the People's Republic of Mongolia (former name), the Polytechnic Institute was separated from the National University of Mongolia and reorganized into an independent university.
Multi-label chest X-ray classification faces three critical challenges: (i) inadequate modeling of inter-pathology dependencies despite clinical co-occurrence patterns, (ii) severe class imbalance (11.2−47.6 N=36,904 images), HP-ViT achieves macro-F1 of 0.924, exact match ratio of 0.842, and PPV of 0.925, representing 1.76 p<0.001 , McNemar’s test on per-sample exact-match correctness). HP-ViT requires only 12.6 M parameters (85
Scene-consistent video generation aims to create videos that explore 3D scenes based on a camera trajectory. Previous methods rely on video generation models with external memory for consistency, or iterative 3D reconstruction and inpainting, which accumulate errors during inference due to incorrect intermediary outputs, non-differentiable processes, and separate models. To overcome these limitations, we introduce “geometry-as-context". It iteratively completes the following steps using an autoregressive camera-controlled video generation model: (1) estimates the geometry of the current view necessary for 3D reconstruction, and (2) simulates and restores novel view images rendered by the 3D scene. Under this multi-task framework, we develop the camera gated attention module to enhance the model's capability to effectively leverage camera poses. During the training phase, text contexts are utilized to ascertain whether geometric or RGB images should be generated. To ensure that the model can generate RGB-only outputs during inference, the geometry context is randomly dropped from the interleaved text-image-geometry training sequence. The method has been tested on scene video generation with one-direction and forth-and-back trajectories. The results show its superiority over previous approaches in maintaining scene consistency and camera control.
Effective and generalizable control in video generation remains a significant challenge. While many methods rely on ambiguous or task-specific signals, we argue that a fundamental disentanglement of “appearance” and “motion” provides a more robust and scalable pathway. We propose FlexAM, a unified framework built upon a novel 3D control signal. This signal represents video dynamics as a point cloud, introducing three key enhancements: multi-frequency positional encoding to distinguish fine-grained motion, depth-aware encoding, and a flexible control signal for balancing precision and generalization. This representation allows FlexAM to effectively disentangle appearance and motion, enabling a wide range of tasks including I2V/V2V editing, camera control, and spatial object editing. Extensive experiments demonstrate that FlexAM achieves superior performance across all evaluated tasks. Codes are available at https://github.com/IGL-HKUST/FlexAM .
In this work, an Al2O3 ceramic slurry was prepared with tert-butanol (TBA) as the solvent and Ni powder as the magnetic primer, followed by freeze casting at a constant cooling temperature. A static magnetic field was applied on both sides of the mold to successfully prepare the bio-inspired Al2O3 porous ceramics with a bidirectional ladder-structure. The circular pores exhibited a ladder-structure along both the freezing and magnetic field directions. Moreover, along the magnetic field direction, a clear phase separation between Ni-rich and Nipoor regions was observed. In the process of directional freezing, with an increase in freezing distance, the size of the ice crystals increased, the pore diameter of the porous ceramics increased, and the pore wall thickness decreased. In addition, Ni particles in the slurry were attracted to both sides of the ceramic scaffolds by the magnetic field, and Ni and ice crystals were distributed in the ladder-structure along the magnetic field direction. The pore structure in the side region of the scaffold (i.e., Ni-rich region) was oriented parallel to the magnetic field direction. The pore structure at the center of the scaffold (i.e., Ni-poor region) was oriented along the freezing direction. Increasing the Ni content (0-9 wt%) in the slurry thereby increased its viscosity and accelerated the ice-front solidification rate(31 -> 67 mu m/s), which consequently reduced the structural wavelength, pore size (37 f 3.5 -> 13 f 1.5 mu m), and wall thickness (71 f 8 -> 18 f 2 mu m) while increasing the linear shrinkage rate (14 f 1 -> 33 f 1 %) of the Al2O3 porous ceramics, thereby decreasing porosity (88 f 1 -> 83 f 1 %) and improving compressive properties (7.2 f 0.5 MPa).
Buckling is a critical issue in ultra-long wind turbine blades with thin-skin, cylindrically curved shells separated by a core structure. Conventional core designs provide limited rotational constraints at shell boundaries, requiring thicker shells to prevent buckling and thereby increasing weight and reducing energy-generation efficiency. Therefore, this study proposed a bio-inspired blade (BE blade) incorporating trabecular cores, modelled after the internal architecture of beetle elytron. In addition to the modified Batdorf's parameter Z, which reflects shell curvature, a new dimensionless parameter eta was introduced to quantify constraints provided by trabecular cores. Numerical modelling, validated using four-point bending tests on carbon fibre composite structures and analytical solutions for buckling loads of curved shells, was applied to investigate the buckling behaviour of BE blades. For typical blade values of Z (8-37), eta is recommended to be 0.25 for 8 <= Z < 28, and 0.05-0.15 for 28 <= Z <= 37, increasing buckling loads by 15%-35% over conventional designs. Ultimately, a new set of displacement field functions was identified and used to develop energy-based theoretical solutions for buckling loads of BE blades, with discrepancies between theoretical and simulation results being mainly within 2% by introducing a design-oriented safety factor C for engineering application.
