We present Free4D, a novel tuning-free framework for 4D scene generation from single image. Existing methods either focus on object-level generation, making scene-level infeasible, or rely large-scale multi-view video datasets expensive training, with limited generalization ability due to the scarcity of data. In contrast, our key insight is distill pre-trained foundation models consistent representation, which offers promising advantages such as efficiency and generalizability. 1) To...
Cell instance segmentation (CIS) via light microscopy and artificial intelligence (AI) is essential to cell gene therapy-based health care management, which offers the hope of revolutionary care. An effective CIS method can help clinicians diagnose neurological disorders quantify how well these deadly respond treatment. To address task challenged by dataset characteristics such as irregular morphology, variation in sizes, adhesion, obscure contours, we propose a novel deep learning model...
A three-terminal refrigerator based on resonant-tunneling quantum wells is proposed. With the help of Landauer formula, expressions for cooling rate and coefficient performance (COP) are derived. The working regions determined three-dimensional projection graphs COP varying with positions two energy levels plotted. Moreover, influence bias voltage, asymmetric factor, temperature difference optimal parameters analyzed in detail. Finally, characteristics case negative discussed.
The transformation effects of metal ions and temperature on the DNA base guanine (G) metal–organic coordination motifs in water have been investigated by scanning tunneling microcopy (STM). G molecules form an ordered hydrogen-bonded structure at water–highly oriented pyrolytic graphite interface. STM observations reveal that canonical G/9H can be transformed into G/(3H,7H) tautomer increasing solution to 38.6 °C. Moreover, bind with G4Fe13+, G3Fe32+, heterochiral intermixed G4Na1+ networks...
Targets location and parameter inversion are always active research field of Ground Penetrating Radar (GPR) useful to address some challenges in civil military applications. Since the amplitude delay receiving signal could correspondingly change due varying dimension, material targets, permittivity background. So, this paper, we present a new framework integrated Generalized Hough Transform (GHT) with neural network reconstruct their non-linear relationship implement targets inversion. The...
In this research, a primitive prediction network embedding Spherical Coordinate Transformation (named SCT-Net), which is simple and end-to-end deep neural network, proposed for instance segmentation of point clouds. The key SCT-Net to excavate the relationship between local neighborhood points. First, in order enhance compacted expression feature, spherical coordinate transformation embedded network. Second, constructed predict grouping proposals classify primitives corresponding each...
Determination of background permittivity and removing the direct wave is one main problems in data processing on Ground Penetrating Radar. The interference will greatly affect accuracy resolution GPR imaging. We propose an f-k filtering approach for solution, which use a difference apparent velocity between reflection from target. Besides, Stolt migration algorithm combined F-K filter with minimum entropy technique proposed to improve focus effect radar image realize precise inversion...
Point cloud semantic segmentation predicts the class of each point, which can help AI machines perceive real 3D world. Recently, precision for large-scale point is limited by complex scenarios, data occlusion, and massive data, remains. This paper proposes neural radiance field convolution to analysis. First, conquer some existing methods represent local space as relative position without considering rotation property cloud. A new spatial direction representation called seven-dimensional...

Freestanding thin film electrodes are competitive candidate materials for high-performance energy stockpile equipment due to their self-supporting structure and because they lack any polymer binder or conductive additive. In our work, a porous carbon nanofiber (PCNF) electrode has been synthesized via convenient low-cost electrospinning approach the following carbonization air etching process. The obtained PCNF sample shows high reversible capacity (1138 mAh g−1 at 0.1 C), remarkable rate...

Different organometallic nanostructures on highly oriented pyrolytic graphite (HOPG) have been synthesized by different metal ions coordinating with 1,4-Dibromo-2,5-diiodobenzene (C 6 H 2 Br I ). Scanning tunneling microscopy (STM) images directly demonstrated the transformation of nanostructure from self-assembled formed C through halogen bond into network, dehalogenated molecules covalent bonded ions. Moreover, varying concentrations or valence states ions, structures shapes and sizes...
Polygonal planes are used to simplify the modeling of building point cloud, which is widely applied for city planning, 3-D cadastral management, and model rendering. Much current research mainly focuses on watertight polygon reconstruction from data with few missing values, highly hypothetical restricted in application. Therefore, this letter proposes a non-watertight PolyFit (NW-PolyFit) algorithm based fit degree connection fitting reconstruct values. First, refine planar structure...
