Stability of surfactant-laden double-layered viscoelastic fluids flowing over an inclined plane
The linear dynamics and instability mechanisms of double-layered weakly viscoelastic fluid flowing over an inclined plane are analyzed in the presence of insoluble surfactant at both the free surface and interface. The constitutive equation of the non-Newtonian flow field follows the rheological property of Walters' $B^{''}$ model. The Orr-Sommerfeld-type boundary value problem is derived using the classical normal-mode approach and numerically solved within the framework of the Chebyshev spect…

Singularity of Cannon-Thurston maps
In a closed fibered hyperbolic 3-manifold M, the inclusion of a fiber S, with S and M lifted to the universal covers gives an exponentially distorted embedding of the hyperbolic plane into hyperbolic 3-space. Nevertheless, Cannon and Thurston showed that there is a map from the circle at infinity of the hyperbolic plane to the 2-sphere at infinity of hyperbolic 3-space. The Cannon-Thurston map is surjective, finite-to-one, and gives a space-filling curve. Here we prove that many natural measure…

Deconstruction of the anisotropic magnetic interactions from spin-entangled optical excitations in van der Waals antiferromagnets
Magneto-optical excitations in antiferromagnetic d systems can originate from a multiplicity of light-spin and spin-spin interactions, as the light and spin degrees of freedom can be entangled. This is exemplified in van der Waals systems with attendant strong anisotropy between in-plane and out- of-plane directions, such as MnPS3 and NiPS3 films studied here. The rich interplay between the magnetic ordering and sub-bandgap optical transitions poses a challenge to resolve the mechanisms driving…

Holographic Gaseous Lenses for High-Power Lasers
The capabilities of the world's highest energy and peak-power pulsed lasers are limited by optical damage, and further advances in high-intensity laser science will require optics that are substantially more robust than existing components. We describe here the experimental demonstration of off-axis diffractive gaseous lenses capable of withstanding extreme laser fluence and immune to cumulative damage. We used less than 8 mJ of energy from interfering ultraviolet laser pulses to holographicall…

Leading up to the government shutdown on Wednesday,
congressional Republicans and Donald Trump have
repeated misleading claims
that Democrats were trying to pass a resolution that would provide
“free healthcare for illegals”.
It’s become a well-rehearsed refrain fueling GOP lawmakers.
At the White House on Wednesday, the JD Vance said the Democrats’ spending plan
“would have undone” the work of the One Big Beautiful Bill Act (OBBBA)
– which en…

The White House published a photo in which Netanyahu is seen forced by Trump to apologize to Qatari PM Al Thani while reading a piece of paper on the phone. I guess the script was 99% sure provided to him by Trump or his administration.

Navy reverses demotion of former White House doctor Ronny Jackson
Rep. Ronny Jackson has announced that the Navy has restored his retired rank of rear admiral. This overturns a 2022 demotion that followed a scathing investigation that found major issues with his behavior while he was the top White House physician. The Texas Republican on Wednesday posted a June 13 letter from Navy Secretary John Phelan saying he had reinstated Jackson to the retired rank of a one-star admiral following a “review of all applicable reports and references.” The Navy confirme…

Our plan for a more secure npm supply chain
GitHub is strengthening npm's security with stricter authentication, granular tokens, and enhanced trusted publishing.

For $reasons I needed a string in an Ansible Jinja2 template which would be a time between 18:00:00 and the following 05:00:00 (an 11 hour span).
The time should be different for each host, spread throughout the range, but should be deterministic (i.e. it will never change for a given host).
The best I could come up with was: https://pa…
