MRI for Lung Cancer Management: Any Closer to Clinical Application?

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Management of lung cancer (LC) encompasses screening, diagnosis, staging, radiotherapy planning and guidance, therapy monitoring and surveillance. Across these domains, magnetic resonance imaging (MRI) offers a range of morphological and functional imaging capabilities—including diffusion‐weighted imaging (DWI), dynamic contrast‐enhanced (DCE)

Assessment of Robustness of MRI Radiomic Features in Four Abdominal Organs: Impact of Deep Learning Reconstruction and Segmentation

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The impact of deep learning (DL) reconstruction and segmentation on MRI radiomics stability has not been fully assessed. Purpose To investigate the effects of acquisition, reconstruction, and segmentation on the reproducibility and variability of radiomic features in abdominal MRI. Study Type Prospective.

Intermittent and Adaptive Control Strategies for Chaos Suppression in a Cancer Model

open access: yesMathematical and Computational Applications
The chaotic dynamics observed in mathematical models of cancer can correspond to the unpredictable tumor growth and treatment responses seen in clinical settings. Suppressing this chaos is a significant challenge in theoretical oncology.

The Bazaar as a Model for Knowledge Work

open access: yesKnowledge and Process Management, EarlyView.
ABSTRACT This paper presents fieldwork that extends existing metaphors of knowledge work as a process shaped by hierarchical or market forces. A qualitative, ethnographic study of six knowledge‐intensive businesses in two countries identifies striking parallels with the Middle Eastern bazaar in contrast to Western impersonal markets and hierarchies. We

Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Impacts of disturbances on bifurcation behaviors in an interconnected power systems

open access: yesAIP Advances
The reliable and stable operation of the power grid is crucial to the national economy, and the existing complex nonlinear phenomena related to disturbances, such as chaotic oscillation accompanied by bifurcation behaviors, are potential threats to ...

Frozen Differential Scattering in Reconfigurable Complex Media

open access: yesLaser &Photonics Reviews, EarlyView.
A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Multimode Phonon Lasing via Self‐Induced Optical Coherent Pumping

open access: yesLaser &Photonics Reviews, EarlyView.
A silicon optomechanical nanobeam generates self‐sustained phonon lasing in multiple competing mechanical modes via self‐pulsing, an intrinsic optical modulation arising from cavity nonlinearity. This self‐organized mechanism enables robust multi‐frequency operation spanning periodic, quasi‐periodic, and chaotic regimes without external modulation. The

Sextupole reduction via chaos suppression at the National Synchrotron Light Source II

open access: yesPhysical Review Accelerators and Beams
We revisit the nonlinear lattice design approach for the National Synchrotron Light Source II (NSLS-II) storage ring. By suppressing chaos, we identify alternative sextupole configurations to the original design, which relied on the conventional strategy

Numerical study on the suppression effect of potassium salt on the infrared radiation signatures of rocket exhaust plumes

open access: yesCase Studies in Thermal Engineering
This work aims to study the suppression effect of potassium salts on the afterburning and infrared radiation of rocket exhaust plumes. In this study, a modified chemical kinetic model of potassium salt was developed, and a plume infrared signature ...
