The recent surge of utilizing deep neural networks for geometric processing and shape modeling has opened up exciting avenues. However, there is a conspicuous lack of research effo…
Surface Extraction from Neural Unsigned Distance Fields
Congyi Zhang, Guying Lin, Lei Yang +5
We propose a method, named DualMesh-UDF, to extract a surface from unsigned distance functions (UDFs), encoded by neural networks, or neural UDFs. Neural UDFs are becoming increasi…
From orthogonal link to phase vortex in generalized dynamical Hopf insulators
Yuxuan Ma, Xin Li, Yu Wang +3
In the creation of Hopf topological matters, the old paradigm is to conceive the Hopf invariant first, and then display its intuitive topology through links. Here we brush aside th…
Random Shortening of Linear Codes and Applications
Xue Chen, Kuan Cheng, Xin Li +1
Random linear codes (RLCs) are well known to have nice combinatorial properties and near-optimal parameters in many different settings. However, getting explicit constructions matc…
MixNet: Toward Accurate Detection of Challenging Scene Text in the Wild
Yu-Xiang Zeng, Jun-Wei Hsieh, Xin Li +1
Detecting small scene text instances in the wild is particularly challenging, where the influence of irregular positions and nonideal lighting often leads to detection errors. We p…
On k-Mer-Based and Maximum Likelihood Estimation Algorithms for Trace Reconstruction
Kuan Cheng, Elena Grigorescu, Xin Li +2
The goal of the trace reconstruction problem is to recover a string given many independent {\em traces} of , where a trace is a subsequence obtained from deletin…
TCEIP: Text Condition Embedded Regression Network for Dental Implant Position Prediction
Xinquan Yang, Jinheng Xie, Xuguang Li +4
When deep neural network has been proposed to assist the dentist in designing the location of dental implant, most of them are targeting simple cases where only one missing tooth i…
Two-Stream Regression Network for Dental Implant Position Prediction
Xinquan Yang, Xuguang Li, Xuechen Li +4
In implant prosthesis treatment, the design of the surgical guide heavily relies on the manual location of the implant position, which is subjective and prone to doctor's experienc…
MorphGANFormer: Transformer-based Face Morphing and De-Morphing
Na Zhang, Xudong Liu, Xin Li +1
Semantic face image manipulation has received increasing attention in recent years. StyleGAN-based approaches to face morphing are among the leading techniques; however, they often…
Analysis of Biomass Sustainability Indicators from a Machine Learning Perspective
Syeda Nyma Ferdous, Xin Li, Kamalakanta Sahoo +1
Plant biomass estimation is critical due to the variability of different environmental factors and crop management practices associated with it. The assessment is largely impacted…
WL-Align: Weisfeiler-Lehman Relabeling for Aligning Users across Networks via Regularized Representation Learning
Li Liu, Penggang Chen, Xin Li +4
Aligning users across networks using graph representation learning has been found effective where the alignment is accomplished in a low-dimensional embedding space. Yet, achieving…
Topological transitions, turbulent-like motion and long-time-tails driven by cell division in biological tissues
Xin Li, Sumit Sinha, T. R. Kirkpatrick +1
The complex spatiotemporal flow patterns in living tissues, driven by active forces, have many of the characteristics associated with inertial turbulence even though the Reynolds n…
Free volume theory explains the unusual behavior of viscosity in a non-confluent tissue during morphogenesis
Rajsekhar Das, Sumit Sinha, Xin Li +2
A recent experiment on zebrafish blastoderm morphogenesis showed that the viscosity (η) of a non-confluent embryonic tissue grows sharply until a critical cell packing fraction (ϕS…
Batch-based Model Registration for Fast 3D Sherd Reconstruction
Jiepeng Wang, Congyi Zhang, Peng Wang +4
3D reconstruction techniques have widely been used for digital documentation of archaeological fragments. However, efficient digital capture of fragments remains as a challenge. In…
Topological phase transitions and Berry-phase hysteresis in exchange-coupled nanomagnets
Ahsan Ullah, Xin Li, Yunlong Jin +6
Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrm…
ImplantFormer: Vision Transformer based Implant Position Regression Using Dental CBCT Data
Xinquan Yang, Xuguang Li, Xuechen Li +3
Implant prosthesis is the most appropriate treatment for dentition defect or dentition loss, which usually involves a surgical guide design process to decide the implant position.…
Information Topology
Xin Li
We introduce \emph{Information Topology}: a framework that unifies information theory and algebraic topology by treating \emph{cycle closure} as the primitive operation of inferenc…
Exceptional points as signatures of dynamical magnetic phase transitions
Kuangyin Deng, Xin Li, Benedetta Flebus
One of the most fascinating and puzzling aspects of non-Hermitian systems is their spectral degeneracies, i.e., exceptional points (EPs), at which both eigenvalues and eigenvectors…
Statistical Mechanical theory for spatio-temporal evolution of Intra-tumor heterogeneity in cancers: Analysis of Multiregion sequencing data
Sumit Sinha, Xin Li, Dave Thirumalai
Heterogeneity in characteristics from one region (sub-population) to another, commonly observed in complex systems, such as glasses and a collection of cells, is hard to describe t…
Mechanical feedback controls the emergence of dynamical memory in growing tissue monolayers
