Identity‐Enabled CDMA LiDAR for Massively Parallel Ranging with a Single‐Element Receiver
Laser &Photonics Reviews, EarlyView.A novel LiDAR system integrates CDMA modulation with a single‐element detector to achieve massive channel parallel 3D imaging. By using a user identification code and a correlation‐based feedback loop, it overcomes signal collisions and the near‐far problem.

Symmetry, Integrability and Geometry: Methods and Applications, 2009 Using the technique of the elliptic Frobenius determinant, we construct new elliptic solutions of the QD-algorithm. These solutions can be interpreted as elliptic solutions of the discrete-time Toda chain as well.

Compact Spectral Imaging: A Review of Miniaturized and Integrated Systems
Laser &Photonics Reviews, EarlyView.This review explores the rapid shift toward compact spectral imaging systems by examining four key design paradigms: Do‐It‐Yourself (DIY) platforms, freeform optics, filter‐on‐chip integration, and multifunctional metasurfaces. The discussion highlights critical applications in medicine, agriculture, and environmental monitoring, providing comparative ...

Global and microlocal aspects of Dirac operators: Propagators and Hadamard states
Mathematische Nachrichten, EarlyView.Abstract We propose a geometric approach to construct the Cauchy evolution operator for the Lorentzian Dirac operator on Cauchy‐compact globally hyperbolic 4‐manifolds. We realize the Cauchy evolution operator as the sum of two invariantly defined oscillatory integrals—the positive and negative Dirac propagators—global in space and in time, with ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

The Symmetrical H_q-Semiclassical Orthogonal Polynomials of Class One
Symmetry, Integrability and Geometry: Methods and Applications, 2009 We investigate the quadratic decomposition and duality to classify symmetrical H_q-semiclassical orthogonal q-polynomials of class one where H_q is the Hahn's operator.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Because of the surging demand for clean energy, the performance and safety of lithium‐ion batteries (LIBs) for energy storage and conversion have received much attention. This study presents a battery thermal management system (BTMS) that combines air cooling with microchannel liquid cooling.

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Bacterial ferredoxins are small iron–sulfur binding proteins that function as soluble electron shuttles between redox enzymes in the cell. Their simple 2×(β–α–β) fold, central metabolic function, and ubiquity across all kingdoms of life have led to the proposal that ferredoxins were likely among the earliest proteins.
