High resolution Fluorescence lifetime IMaging Micro-Endoscopy (FLIMME) using a single multimode fiber
Endoscopic optical imaging using a single multimode fiber (MMF) has emerged as a promising approach for highly compact, minimally invasive, and high-resolution imaging. Unlike conventional fiber bundles, MMF-based endomicroscopes exploit the controlled excitation of multiple spatially overlapping modes in a single MMF. of core diameters of tens of micrometers. to deliver and collect light to form images with sub-micrometer resolution. Here, we introduce a fluorescence lifetime imaging microscop…

Atomic networks as highways for holes in oxygen-deficient amorphous oxides
Oxygen-deficient amorphous tellurium oxides ($a$-TeO$_x$) have recently challenged the intrinsic hole mobility limits of amorphous oxides, with thin-film transistors reaching mobilities up to 15 cm$^{2}$V$^{-1}$s$^{-1}$ upon Se doping. However, the atomistic origins of this behavior, and its seeming contradiction with established semiconductor physics, have remained unresolved. Here, we combine machine-learning-accelerated ab initio molecular dynamics with hybrid-functional defect calculations …

Charge dynamics of individual conductance channels within a percolation network of a nano-patterned nanocrystal quantum dot solid
Colloidal nanocrystal quantum dots (QD) enable the bottom-up assembly of designer solids. Among the multitudinous applications of QD solids, there has been great success in exploiting the tunable optical properties for LED displays, lighting, bioimaging and diagnostics. Applications dependent on electrical properties such as solar cells, photodetectors, and transistors have fallen short of their full potential because of poor control over electrical properties, and some of applications with the…

Rewatching the 1984 film version of 1984, as I haven't seen it since high school. They showed it to us in class in the 90s. Been a lot of years. John Hurt ftw

Exclusive: LNG Expansion Brings New Health Risks to Kitimat
The project’s fast-tracked second phase would push a key pollutant far above current limits, documents reveal.
"Nicknamed the “Eye of Sauron” by Kitimat residents, the flare from LNG Canada frequently engulfs the town in black, hydrocarbon-filled smoke, sometimes reaching the height of a 30-storey building."

US attorney's new policy on charges for carrying rifles and shotguns in DC
Federal prosecutors in the nation’s capital will no longer bring felony charges against people for possessing rifles or shotguns in the District of Columbia. That's according to new policy adopted by the leader of the nation’s largest U.S. attorney’s office. That office will continue to pursue charges when someone is accused of using a shotgun or rifle in a violent crime or has a criminal record that makes it illegal to have a firearm. U.S. Attorney Jeanine Pirro said in a statement that …

Optical Spectroscopy Reveals Hidden Neutron-capture Elemental Abundance Differences among APOGEE-identified Chemical Doppelgängers
Grouping stars by chemical similarity has the potential to reveal the Milky Way's evolutionary history. The APOGEE stellar spectroscopic survey has the resolution and sensitivity for this task. However, APOGEE lacks access to strong lines of neutron-capture elements ($Z > 28$) which have nucleosynthetic origins that are distinct from those of the lighter elements. We assess whether APOGEE abundances are sufficient for selecting chemically similar disk stars by identifying 25 pairs of chemical `…

Fourier Learning Machines: Nonharmonic Fourier-Based Neural Networks for Scientific Machine Learning
We introduce the Fourier Learning Machine (FLM), a neural network (NN) architecture designed to represent a multidimensional nonharmonic Fourier series. The FLM uses a simple feedforward structure with cosine activation functions to learn the frequencies, amplitudes, and phase shifts of the series as trainable parameters. This design allows the model to create a problem-specific spectral basis adaptable to both periodic and nonperiodic functions. Unlike previous Fourier-inspired NN models, the …

Spatiotemporal Nonlinear Pulse Dynamics in Multimode Silicon Nitride Waveguides
We present an open-source multimode nonlinear Schrödinger equation-based simulation to investigate spatiotemporal nonlinear pulse propagation in thin-film silicon nitride (SiN) waveguides. Using this framework, we analyze femtosecond pulse evolution under diverse excitation conditions in a 6 μm wide SiN waveguide supporting six TE modes. Our results reveal that mode selection and power distribution critically govern nonlinear coupling, soliton fission, and dispersive wave generation, leading …
