Full-field spectroscopic measurement of the X-ray beam from a multilayer monochromator using a hyperspectral X-ray camera

Multilayer monochromator devices are commonly used at (imaging) beamlines of synchrotron facilities to shape the X-ray beam to relatively small bandwidth and high intensity. However, stripe artefacts are often observed and can deteriorate the image quality. Although the intensity distribution of these artefacts has been described in the literature, their spectral distribution is currently unknown. To assess the spatio-spectral properties of the monochromated X-ray beam, the direct beam has been measured for the first time using a hyperspectral X-ray detector. The results show a large number of spectral features with different spatial distributions for a [Ru, B4C] strip monochromator, associated primarily with the higher-order harmonics of the undulator and monochromator. It is found that their relative contributions are sufficiently low to avoid an influence on the imaging data. The [V, B4C] strip suppresses these high-order harmonics even more than the former, yet at the cost of reduced efficiency.

Hyperuniformity and anti-hyperuniformity in one-dimensional substitution tilings

This work considers the scaling properties characterizing the hyperuniformity (or anti-hyperuniformity) of long-wavelength fluctuations in a broad class of one-dimensional substitution tilings. A simple argument is presented which predicts the exponent α governing the scaling of Fourier intensities at small wavenumbers, tilings with α > 0 being hyperuniform, and numerical computations confirm that the predictions are accurate for quasiperiodic tilings, tilings with singular continuous spectra and limit-periodic tilings. Quasiperiodic or singular continuous cases can be constructed with α arbitrarily close to any given value between −1 and 3. Limit-periodic tilings can be constructed with α between −1 and 1 or with Fourier intensities that approach zero faster than any power law.

Meet the man behind the art garden on the Hyperion Bridge in Atwater

On the median on the Atwater Village side of the Hyperion bridge, Jeff Harmes built a garden. It's an act he calls "taking nothing and making it into something that everyone can get something out of, that can inspire everyone."

Having lived on the streets for 30 years, Jeff says grew to hate litter. He used to sweep street gutters with a piece of cardboard and remove trash packed into the forks of trees. He thought of them as small acts that would go mostly unnoticed.

On a whim last spring, he started tilling the median — or "the island," as he likes to call it ... although "oasis" is more like it, now. He made rock sculptures from stones he scrounged out of the L.A. River. In celebration of spring, he made a peace sign out of flowers. 

He says he doesn't know much about gardening or landscaping. He learns as he goes and looks to commuters for suggestions. In the absence of running water, he relies on rainfall.

Vibrant succulents sit next to kitschy items like gnomes and plastic flamingos. Intricate formations of seashells and stones contrast starkly against the neatly patted dirt. A young girl even donated her seashell collection for the peace sign. 

Recently, though, a vandal smashed the peace sign and wrecked Jeff's plants, including his squash crop. With help from the neighborhood, Jeff has been able to rebuild the garden. New plants have sprouted and the stonework has been repaired.

Jeff says his new goal with the garden is for people to draw something positive from it. "I want hate to be transferred into something beautiful," he said. Moving forward, he hopes to expand it down the island. 

(Note: This post has been edited. The original called it a "meridian," which is an invisible geographic line. "Median" is correct.)

Unbounded Kobayashi hyperbolic domains in $mathbb C^n$. (arXiv:1911.05632v2 [math.CV] UPDATED)

We first give a sufficient condition, issued from pluripotential theory, for an unbounded domain in the complex Euclidean space $mathbb C^n$ to be Kobayashi hyperbolic. Then, we construct an example of a rigid pseudoconvex domain in $mathbb C^3$ that is Kobayashi hyperbolic and has a nonempty core. In particular, this domain is not biholomorphic to a bounded domain in $mathbb C^3$ and the mentioned above sufficient condition for Kobayashi hyperbolicity is not necessary.
