Exploiting scattering-based point spread functions for snapshot 5D and modality-switchable lensless imaging
Snapshot multi-dimensional imaging offers a promising alternative to traditional low-dimensional imaging techniques by enabling the simultaneous capture of spatial, spectral, polarization, and other information in a single shot for improved imaging speed and acquisition efficiency. However, existing snapshot multi-dimensional imaging systems are often hindered by their large size, complexity, and high cost, which constrain their practical applicability. In this work, we propose a compact lensle…

If you see posts about how Netanyahu is playing Trump — which is plausible, Trump’s a vain nincompoop and people play him all the time — please •mind the undertone•.
Are they really taking about Netanyahu? Or is “Netanyahu” standing in for a larger group?
Is the focus on Trump being a gullible fool? Or is the focus on insinuating that some shadowy group secretly controls world politics?
Take a moment to digest this from @…, notice and recognize the pattern, and be aware as you scroll.

Pretty amazing imaging technique from @… “We developed WHOLISTIC, a method to image second-timescale, time-varying intracellular dynamics across cell-types of the vertebrate body.”

Sociotechnical Imaginaries of ChatGPT in Higher Education: The Evolving Media Discourse
This study investigates how U.S. news media framed the use of ChatGPT in higher education from November 2022 to October 2024. Employing Framing Theory and combining temporal and sentiment analysis of 198 news articles, we trace the evolving narratives surrounding generative AI. We found that the media discourse largely centered on institutional responses; policy changes and teaching practices showed the most consistent presence and positive sentiment over time. Conversely, coverage of topics su…

QUTCC: Quantile Uncertainty Training and Conformal Calibration for Imaging Inverse Problems
Deep learning models often hallucinate, producing realistic artifacts that are not truly present in the sample. This can have dire consequences for scientific and medical inverse problems, such as MRI and microscopy denoising, where accuracy is more important than perceptual quality. Uncertainty quantification techniques, such as conformal prediction, can pinpoint outliers and provide guarantees for image regression tasks, improving reliability. However, existing methods utilize a linear consta…

Advanced X-rays techniques for research-oriented high-resolution imaging of articular cartilage: a scoping review
Articular cartilage is a musculoskeletal soft tissue renowned for its unique mechanical properties. Understanding both its hierarchical structure and the interplay between its constituents could shed light on the mechanical competence of the tissue. Therefore, rheologic approaches based on high-resolution non-destructive imaging techniques are desired. In this context, X-ray imaging could ideally accomplish this task. Nevertheless, the nature of articular cartilage translates into poor contrast…

Novel techniques of imaging interferometry analysis to study gas and plasma density for laser-plasma experiments
Laser-plasma based experiments are always more demanding about the plasma characteristics which need to be generated during the interaction. This is valid for laser-plasma acceleration as well as for inertial confinement fusion experiments. Most of these experiments are moving toward high repetition rate operation regimes, making even more demanding the requests on the plasma sources and the diagnostics to be implemented.\\ Interferometry is one of the most used methods to characterize these so…

Research on Ultrasonic Imaging Systems Based on Scattering Field Theory
In an ultrasonic array system, increasing the aperture size to achieve a high resolution requires more transmit and receive channels, thus making it essential to have an analysis technique that can reconstruct the shape and physical properties of scatterers in a finite time based on measurement data obtained from numerous ultrasonic elements. Herein, we developed an ultrasound imaging technique using a two-dimensional ultrasonic array system comprising N^2 transmitter/receiver pairs and a techn…
