Introduction: Greater white matter hyperintensities (WMHs) on magnetic resonance imaging (MRI) are seen with transactive response DNA-binding protein 43 (TDP-43) pathology in frontotemporal lobar degeneration (FTLD-TDP). WMH associations with TDP-43 pathology in Alzheimer's disease (AD-TDP) remain unclear.
Methods: A total of 157 participants from Mayo Clinic Rochester with autopsy-confirmed AD, known TDP-43 status, and antemortem fluid-attenuated inversion recovery (FLAIR) MRI were included.

To enhance the efficacy of multimedia quantum processing and diminish processing overhead, an advanced multimedia quantum representation model and quantum video display framework are devised. A range of framework processing operators are also developed, including an image color compensation operator, a bit plane inversion operator, and a frame displacement operator. In addition, to address image security issues, two quantum image operations have been proposed: color transformation operation and pixel blending operation.

In this Letter, by interfacing traditional semiconductor quantum dots with industry-grade plasmonic transducer technology, we demonstrate that the near-field-induced thermal gradient can facilitate the requisite population inversion for coherent phonon amplification and lasing at the nanoscale. Our detailed analysis uncovers both the characteristics and parameter sensitivity of inversion and relaxation oscillations in the system, thereby unveiling hitherto unexplored opportunities for leveraging plasmonic near-field effects in the context of quantum thermodynamics and phononics.

Natural gas (NG) is a promising alternative to diesel for sustainable transport, potentially reducing GHG and air quality emissions significantly. However, the GHG benefits hinge on managing methane slip, the unburned methane in the exhaust of NG engines, which carries a significant global warming potential. The CH slip from NG engines is highly dependent on engine type and operation, and effective greenhouse gas emission mitigation requires that the actual operation of real-world engines is monitored.

Clinical Case: We present the case of a prenatally diagnosed hepato-omphalocele, without associated abnormalities. At week 37, botulinum toxin was injected in the right hemiabdomen under fetal and maternal sedation.
