Abstract: Production and manipulation of orbital angular momentum (OAM) of coherent soft x-ray beams is demonstrated utilizing consecutive diffractive optics. OAM addition is observed upon passing the beam through consecutive fork gratings. The OAM of the beam was found to be decoupled from its spin angular momentum (SAM). Practical implementation of angular momentum control by consecutive devices in the x-ray regime opens new experimental opportunities, such as direct measurement of OAM beams without resorting to phase sensitive techniques, including holography. OAM analyzers utilizing fork gratings can be used to characterize the beams produced by synchrotron and free electron lasers sources; they can also be used in scattering experiments.

NFL power ratings: Patriots vs. Seahawks Super Bowl spread not buying Drake Maye's chances

Since the Trump administration launched high-intensity immigration sweeps this year,
federal agents have routinely countered protestors using crowd control weapons
— rubber bullets, flash-bang grenades, tear gas and pepper balls.
They’ve fired on American citizens and noncitizens alike in ways that some experts say might be criminal.

Trump’s Immigration Forces Deploy “Less Lethal” Weapons in Dangerous Ways, Skirting Rules and Maiming Protesters
Civil rights and weapons experts cite the consequences of federal agents’ use of crowd control weapons: religious leaders shot with pepper balls and noxious chemicals. A nurse nearly blinded by tear gas. Protestors trapped, struggling to breathe.

The #roundhouse, now, at last, with electric lights (from its own solar panels).

There are two reasons that Motability includes “premium” brands:
1/ they are often the ones that meet the needs of the users with features like parking assistance for those who cannot see behind them
2/ the leases are often cheaper than non premium brands as their resale value is so much higher.
The effect of these changes might well be that Mobility actually costs the government MORE money 🤦‍♀️

Motability Scheme makes ambitious goal that half of Scheme vehicles leased from 2035 will be British built
Motability Scheme sets ambition for 50% of all vehicles leased to be British built from 2035  Scheme is a lifeline for disabled people and will now further support the UK economy  With government and industry support, ambitious commitment could create demand for 150,000 vehicles annually, boosting jobs and driving new investment  Premium brand vehicles, including Mercedes Benz and BMW, removed from the Scheme

I'm working with household legislators to enact a Dad Congestion Pricing scheme. We charge a kid $0.25 for every "hey dad?". A white paper produced by the Dept of Annoyance shows that a modest fee structure could bring the rate of "hey dad?"s down to a rate of around one or two per minute, while not being so burdensome as to hinder kids from saying things like "hey dad? the microwave is on fire."

"the assets of British banks ‘mostly consist of claims on other banks. Their liabilities are mainly obligations to other financial institutions. Lending to firms and individuals engaged in the production of goods and services – which most people would imagine was the principal business of a bank – amounts to about 3 per cent of that total.’"
It's not for nothing that the medieval church -- like modern Islam -- considered
