Application of Machine Learning in the Diagnosis and Prognosis of Mild Traumatic Brain Injury Using Diffusion Tensor Imaging: A Systematic Review

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Traumatic Brain Injury (TBI) is a global health concern, with mild TBI (mTBI) being the most common form. Despite its prevalence, accurately diagnosing mTBI remains a significant challenge. While advanced neuroimaging techniques like diffusion tensor imaging (DTI) offer promise for more robust diagnosis, their clinical application ...

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics

Laser &Photonics Reviews, EarlyView.
A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

Pseudomagnetic Control of Light Waves in the Electrically Tunable Photonic Crystals with Deformation Engineering

Laser &Photonics Reviews, EarlyView.
This work presents a triaxially deformed photonic crystal cavity on the SOI substrate, enabling the localization and resonating of photons via pseudomagnetic fields. Through coupling with Si waveguides and leveraging the thermo‐optic effect, electrically tunable pseudo‐magnetism‐induced optical resonances can be achieved in the photonic integrated ...

Coordinated control of active disturbance rejection and grid voltage feedforward for grid‐connected inverters

IET Power Electronics, EarlyView., 2022
This paper introduces the research on the inductance‐capacitor‐capacitor‐inductance grid‐connected inverter using active disturbance rejection and grid voltage feedforward coordinated control technology. The pade approximation is performed on the inductance‐capacitor‐capacitor‐inductance filter to derive the first‐order discretization mathematical ...

Beyond Moral Outrage: The Role of the Ingroup in Online Condemnations

Psychology &Marketing, EarlyView.
ABSTRACT Although expressions of condemnation are pervasive on social media and often shape the narratives of traditional news outlets, brands continue to struggle with predicting and managing these responses effectively. To address this challenge, it is crucial to first understand the underlying reasons for such behavior.
