  text: Fast-emitting scintillators are essential for advanced diagnostic techniques,
    yet many suffer from low radiation attenuation. This trade-off is particularly
    pronounced in polymer scintillators, which, despite their fast emission, exhibit
    low density and low atomic numbers, limiting the radiation attenuation factor,
    resulting in low detection efficiency. Here, we overcome this limitation by creating
    a heterostructure scintillator of alternating nanometric layers, combining fast
    light-emitting polymer scintillator layers and transparent stopping layers with
    a high radiation attenuation factor. The nanolayer thicknesses are tuned to optimize
    the penetration depth of recoil electrons in active emissive layers, maximizing
    the conversion of X-rays to visible light. This design increases light output
    by up to 1.5 times and enhances imaging resolution by a factor of 2 compared to
    homogeneous polymer scintillators due to the ability to use thinner samples. These
    results demonstrate the potential of heterostructure scintillators as next-generation
    detector materials, overcoming the limitations of homogeneous scintillators.

  text: In X-ray tubes, more than 99% of the kilowatts of power supplied to generate
    X-rays via bremsstrahlung is lost as heat in the anode. Therefore, thermal management
    is a critical barrier to the development of more powerful X-ray tubes with higher
    brightness and spatial coherence, which are needed to translate imaging modalities
    such as phase-contrast imaging to the clinic. In rotating anode X-ray tubes, the
    most common design, thermal radiation is a bottleneck that prevents efficient
    cooling of the anode─the hottest part of the device by far. We predict that nanophotonic
    patterning of the anode of an X-ray tube enhances heat dissipation via thermal
    radiation, enabling it to operate at higher powers without an increase in temperature.
    The focal spot size, which is related to the spatial coherence of generated X-rays,
    can also be reduced at a constant temperature. A major advantage of our “nanophotonic
    thermal management” approach is that in principle, it allows complete control
    over the spectrum and direction of thermal radiation, which can lead to optimal
    thermal routing and improved performance.

  text: Metasurfaces, ultrathin structures composed of subwavelength optical elements,
    have revolutionized light manipulation by enabling precise control over electromagnetic
    waves’ amplitude, phase, polarization, and spectral properties. Concurrently,
    computational imaging leverages algorithms to reconstruct images from optically
    processed signals, overcoming the limitations of traditional imaging systems.
    This Perspective explores the synergistic integration of metaoptics and computational
    imaging, “metaoptic computational imaging”, which combines the physical wavefront
    shaping ability of metasurfaces with advanced computational algorithms to enhance
    imaging performance beyond conventional limits. We discuss how metaoptic computational
    imaging addresses the inherent limitations of single-layer metasurfaces in achieving
    multifunctionality without compromising efficiency. By treating metasurfaces as
    physical preconditioners and codesigning them with reconstruction algorithms through
    end-to-end (inverse) design, it is possible to jointly optimize the optical hardware
    and computational software. Advanced applications and new frontiers in the field
    enabled by metaoptic computational imaging are highlighted, including phase imaging
    and quantum state measurement.

  text: We present a framework for the end-to-end optimization of metasurface imaging
    systems that reconstruct targets using compressed sensing, a technique for solving
    underdetermined imaging problems when the target object exhibits sparsity (e.g.,
    the object can be described by a small number of nonzero values, but the positions
    of these values are unknown). We nest an iterative, unapproximated compressed
    sensing reconstruction algorithm into our end-to-end optimization pipeline, resulting
    in an interpretable, data-efficient method for maximally leveraging metaoptics
    to exploit object sparsity. We apply our framework to super-resolution imaging
    and high-resolution depth imaging with a phase-change material. In both situations,
    our end-to-end framework effectively optimizes metasurface structures for compressed
    sensing recovery, automatically balancing a number of complicated design considerations
    to select an imaging measurement matrix from a complex, physically constrained
    manifold with millions of dimensions. The optimized metasurface imaging systems
    are robust to noise, significantly improving over random scattering surfaces and
    approaching the ideal compressed sensing performance of a Gaussian matrix, showing
    how a physical metasurface system can demonstrably approach the mathematical limits
    of compressed sensing.

  text: 'Progress in structural membrane biology has been significantly accelerated
    by the ongoing ''Resolution Revolution'' in cryo electron microscopy (cryo-EM).
    In particular, structure determination by single particle analysis has evolved
    into the most powerful method for atomic model building of multisubunit membrane
    protein complexes. This has created an ever increasing demand in cryo-EM machine
    time, which to satisfy is in need of new and affordable cryo electron microscopes.
    Here, we review our experience in using the JEOL CRYO ARM 200 prototype for the
    structure determination by single particle analysis of three different multisubunit
    membrane complexes: the Thermus thermophilus V-type ATPase VO complex, the Thermosynechococcus
    elongatus photosystem I monomer and the flagellar motor LP-ring from Salmonella
    enterica.'

  text: Electrically tunable lenses (ETLs) are those with the ability to alter their
    optical power in response to an electric signal. This feature allows such systems
    to not only image the areas of interest but also obtain spatial depth perception
    (depth of field, DOF). The aim of the present study was to develop an ETL-based
    imaging system for quantitative surface analysis. Firstly, the system was calibrated
    to achieve high depth resolution, warranting the accurate measurement of the depth
    and to account for and correct any influences from external factors on the ETL.
    This was completed using the Tenengrad operator which effectively identified the
    plane of best focus as demonstrated by the linear relationship between the control
    current applied to the ETL and the height at which the optical system focuses.
    The system was then employed to measure amplitude, spatial, hybrid, and volume
    surface texture parameters of a model material (pharmaceutical dosage form) which
    were validated against the parameters obtained using a previously validated surface
    texture analysis technique, optical profilometry. There were no statistically
    significant differences between the surface texture parameters measured by the
    techniques, highlighting the potential application of ETL-based imaging systems
    as an easily adaptable and low-cost alternative surface texture analysis technique
    to conventional microscopy techniques

  text: Rest-frame ultraviolet (UV) emission lines probe electron densities, gas-phase
    abundances, metallicities, and ionization parameters of the emitting star-forming
    galaxies and their environments. The strongest main UV emission line, Lyα, has
    been instrumental in advancing the general knowledge of galaxy formation in the
    early universe. However, observing Lyα emission becomes increasingly challenging
    at z ≳ 6 when the neutral hydrogen fraction of the circumgalactic and intergalactic
    media increases. Secondary weaker UV emission lines provide important alternative
    methods for studying galaxy properties at high redshift. We present a large sample
    of rest-frame UV emission line sources at intermediate redshift for calibrating
    and exploring the connection between secondary UV lines and the emitting galaxies’
    physical properties and their Lyα emission. The sample of 2052 emission line sources
    with 1.5 < z < 6.4 was collected from integral field data from the MUSE-Wide and
    MUSE-Deep surveys taken as part of Guaranteed Time Observations. The objects were
    selected through untargeted source detection (i.e., no preselection of sources
    as in dedicated spectroscopic campaigns) in the three-dimensional MUSE data cubes.
    We searched optimally extracted one-dimensional spectra of the full sample for
    UV emission features via emission line template matching, resulting in a sample
    of more than 100 rest-frame UV emission line detections. We show that the detection
    efficiency of (non-Lyα) UV emission lines increases with survey depth, and that
    the emission line strength of He IIλ1640 Å, [O III] λ1661 + O III] λ1666, and
    [Si III] λ1883 + Si III] λ1892 correlate with the strength of [C III] λ1907 +
    C III] λ1909. The rest-frame equivalent width (EW0) of [C III] λ1907 + C III]
    λ1909 is found to be roughly 0.22 ± 0.18 of EW0(Lyα). We measured the velocity
    offsets of resonant emission lines with respect to systemic tracers. For C IVλ1548
    + C IVλ1551 we find that ΔvC IV ≲ 250 km s−1, whereas ΔvLyα falls in the range
    of 250−500 km s−1 which is in agreement with previous results from the literature.
    The electron density ne measured from [Si III] λ1883 + Si III] λ1892 and [C III]
    λ1907 + C III] λ1909 line flux ratios is generally < 105 cm−3 and the gas-phase
    abundance is below solar at 12 + log10(O/H)≈8. Lastly, we used “PhotoIonization
    Model Probability Density Functions” to infer physical parameters of the full
    sample and individual systems based on photoionization model parameter grids and
    observational constraints from our UV emission line searches. This reveals that
    the UV line emitters generally have ionization parameter log10(U) ≈ −2.5 and metal
    mass fractions that scatter around Z ≈ 10−2, that is Z ≈ 0.66 Z⊙. Value-added
    catalogs of the full sample of MUSE objects studied in this work and a collection
    of UV line emitters from the literature are provided with this paper.

  text: We present the results from a MUSE survey of twelve z ≃ 3.15 quasars, which
    were selected to be much fainter (20 < iSDSS < 23) than in previous studies of
    giant Ly α nebulae around the brightest quasars (16.6 < iAB < 18.7). We detect
    H I Ly α nebulae around 100 per cent of our target quasars, with emission extending
    to scales of at least 60 physical kpc, and up to 190 pkpc. We explore correlations
    between properties of the nebulae and their host quasars, with the goal of connecting
    variations in the properties of the illuminating QSO to the response in nebular
    emission. We show that the surface brightness profiles of the nebulae are similar
    to those of nebulae around bright quasars, but with a lower normalization. Our
    targeted quasars are on average 3.7 mag (≃30 times) fainter in UV continuum than
    our bright reference sample, and yet the nebulae around them are only 4.3 times
    fainter in mean Ly α surface brightness, measured between 20 and 50 pkpc. We find
    significant correlations between the surface brightness of the nebula and the
    luminosity of the quasar in both UV continuum and Ly α. The latter can be interpreted
    as evidence for a substantial contribution from unresolved inner parts of the
    nebulae to the narrow components seen in the Ly α lines of some of our faint quasars,
    possibly from the inner circumgalactic medium or from the host galaxy’s interstellar
    medium.

  at the European Organisation for Astronomical Research in the Southern Hemisphere
  under the MUSE GTO programme. The major analysis and production of figures in this
  work was conducted in Python, using standard libraries which include NumPy (Harris
  et al. 2020), SciPy (Virtanen et al. 2020), Matplotlib (Hunter 2007) and the interactive
  command shell IPython (Pérez & Granger 2007). This research also made use of Astropy,
  a community-developed core Python package for Astronomy (Astropy Collaboration et
  al. 2013), and Photutils, an Astropy package for detection and photometry of astronomica
  sources (Bradley et al. 2019). The python interface dustmaps (Green 2018) was used
  to query galactic extinction maps. topcat, a graphical tool for manipulating tabular
  data, was also utilized in this analysis (Taylor 2005). This research has made use
  of the "Aladin sky atlas" developed at CDS, Strasbourg Observatory, France (Bonnarel
  et al. 2000).

  text: 'By codesigning a metaoptical front end in conjunction with an image‐processing
    back end, we demonstrate noise sensitivity and compactness substantially superior
    to either an optics‐only or a computation‐only approach, illustrated by two examples:
    subwavelength imaging and reconstruction of the full polarization coherence matrices
    of multiple light sources. Our end‐to‐end inverse designs couple the solution
    of the full Maxwell equations—exploiting all aspects of wave physics arising in
    subwavelength scatterers—with inverse‐scattering algorithms in a single large‐scale
    optimization involving  degrees of freedom. The resulting structures scatter light
    in a way that is radically different from either a conventional lens or a random
    microstructure, and suppress the noise sensitivity of the inverse‐scattering computation
    by several orders of magnitude. Incorporating the full wave physics is especially
    crucial for detecting spectral and polarization information that is discarded
    by geometric optics and scalar diffraction theory.'

  text: Segmentation is the process of partitioning digital images into meaningful
    regions. The analysis of biological high content images often requires segmentation
    as a first step. We propose ilastik as an easy-to-use tool which allows the user
    without expertise in image processing to perform segmentation and classification
    in a unified way. ilastik learns from labels provided by the user through a convenient
    mouse interface. Based on these labels, ilastik infers a problem specific segmentation.
    A random forest classifier is used in the learning step, in which each pixel's
    neighborhood is characterized by a set of generic (nonlinear) features. ilastik
    supports up to three spatial plus one spectral dimension and makes use of all
    dimensions in the feature calculation. ilastik provides realtime feedback that
    enables the user to interactively refine the segmentation result and hence further
    fine-tune the classifier. An uncertainty measure guides the user to ambiguous
    regions in the images. Real time performance is achieved by multi-threading which
    fully exploits the capabilities of modern multi-core machines. Once a classifier
    has been trained on a set of representative images, it can be exported and used
    to automatically process a very large number of images (e.g. using the CellProfiler
    pipeline). ilastik is an open source project and released under the BSD license
    at www.ilastik.org.
