Minimally Invasive, Bioadaptive Multimodal Sensor Probe with Safe Deployment for Real‐Time Acute Compartment Syndrome Diagnosis

Advanced Science, EarlyView.
A soft, minimally invasive multimodal sensor probe integrates intracompartmental pressure, tissue oxygen saturation, and blood flow sensors into a single platform. By enabling precise measurements and capturing correlations among pressure, oxygenation, and vascular dynamics, the system provides a comprehensive physiological assessment, thereby ...

Accurate and Efficient End‐Effector Tracking for Quadrupedal Mobile Manipulators through Coordinated Motion and Decoupled Control

Advanced Intelligent Systems, EarlyView.
This article proposes a method that combines coordinated trajectory generation with decoupled tracking control to improve end‐effector tracking accuracy for quadrupedal mobile manipulators. By leveraging whole‐body motion and modeling subsystems independently with interaction forces, the method achieves significant reductions in tracking error and ...

Accurate Analytical Approximation for the Bessel Function J₂(x)

Mathematical and Computational Applications
We obtain an accurate analytic approximation for the Bessel function J2(x) using an improved multipoint quasirational approximation technique (MPQA). This new approximation is valid for all real values of the variable x, with a maximum absolute error of ...

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift

Annalen der Physik, EarlyView.
The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

Received Probability of Vortex Modes Carried by Localized Wave of Bessel–Gaussian Amplitude Envelope in Turbulent Seawater

Journal of Marine Science and Engineering, 2019
By using the two-frequency coherence function model of a beam in a turbulent medium and the localized wave theory of the polychromatic beam, we develop the spectrum average mutual coherence function of the localized wave of Bessel−Gaussian ...

Fabrication of Biocompatible Helical Fibers Using an Optical Vortex Beam

Chemistry – An Asian Journal, EarlyView.
A helical gel fiber was fabricated through the photopolymerization of poly(ethylene glycol) using an optical vortex beam. The helical structure was imparted during photopolymerization because of the orbital angular momentum of the optical vortex beam.
