DetectGPT: Zero-Shot Machine-Generated Text Detection using Probability Curvature [PDF]

International Conference on Machine Learning, 2023
The increasing fluency and widespread usage of large language models (LLMs) highlight the desirability of corresponding tools aiding detection of LLM-generated text.

Berry curvature dipole senses topological transition in a moiré superlattice [PDF]

Nature Physics, 2022
Topological aspects of the electron wave function—including the Berry curvature and Chern number—play a crucial role in determining the physical properties of materials.

Abnormal Seebeck Effect in Vertically Stacked 2D/2D PtSe2/PtSe2 Homostructure

Advanced Science, 2022
When a thermoelectric (TE) material is deposited with a secondary TE material, the total Seebeck coefficient of the stacked layer is generally represented by a parallel conductor model.

Alternatingly Stacked Low‐ and High‐Resistance PtSe2/PtSe2 Homostructures Boost Thermoelectric Power Factors

Advanced Electronic Materials, 2023
2D transition‐metal dichalcogenide (TMDC) materials are promising candidates with excellent thermoelectric (TE) properties owing to their low dimensionality in electronic and phonon transport. However, the considerable coupling of the Seebeck coefficient

Magnonic band spectrum of spin waves in an elliptical helix [PDF]

Royal Society Open Science, 2018
We show that the spin-wave spectrum in an elliptical helix has a band character. The size of the first band gap calculated using the perturbation theory is shown to scale as square root of the eccentricity.

Gaussian curvature dilutes the nuclear lamina, favoring nuclear rupture, especially at high strain rate

Nucleus, 2022
Nuclear rupture has long been associated with deficits or defects in lamins, with recent results also indicating a role for actomyosin stress, but key physical determinants of rupture remain unclear.

Semianalytic calculation of gravitational wave spectrum nonlinearly induced from primordial curvature perturbations [PDF]

Physical Review D, 2018
Whether or not the primordial gravitational wave (GW) produced during inflation is sufficiently strong to be observable, GWs are necessarily produced from the primordial curvature perturbations in the second order of perturbation.

Robustness via Curvature Regularization, and Vice Versa [PDF]

Computer Vision and Pattern Recognition, 2018
State-of-the-art classifiers have been shown to be largely vulnerable to adversarial perturbations. One of the most effective strategies to improve robustness is adversarial training.

Convergence for global curve diffusion flows

Mathematics in Engineering, 2022
In this note we establish exponentially fast smooth convergence for global curve diffusion flows, and discuss open problems relating embeddedness to global existence (Giga's conjecture) and the shape of Type I singularities (Chou's conjecture).

Research on Deformation Reconstruction Based on Structural Curvature of CFRP Propeller With Fiber Bragg Grating Sensor Network

Photonic Sensors, 2022
The deformation and reconstruction of the composite propeller under the static load in the laboratory is studied so as to provide the basic research for the deformation and reconstruction of the underwater deformed propeller. The fiber Bragg grating (FBG)
