Trump’s fragile agreement with Iran has introduced a new variable into this year’s midterm elections.
Democratic candidates have assailed the agreement,
arguing that the president accepted unfavorable terms to try to end an unnecessary war that hurt the economy.

How Trump’s Fragile Agreement With Iran Is Shaping the Midterms
Democrats say the president started an economically painful war that resulted in nothing positive. Republicans are more divided, even as they show some signs of relief at falling gas prices.

Abstract: Time-of-flight magnetic resonance angiography (TOF-MRA) is widely used for structural vascular imaging, but extracting functional hemodynamics like blood velocity typically requires supplementary phase-contrast scans. This study proposes a novel, physics-informed computational framework to extract variable fluid velocity directly from standard TOF-MRA signal profiles. We analytically expand the Bloch equations into Bloch-McConnell flow equations, establishing a mathematical relationship between the spatial decay of longitudinal magnetization and fluid velocity. To validate this derivation and overcome the limitations of constant-velocity assumptions, a MATLAB simulation framework was developed to model fluid flow in two variable-geometry flowing tube cases i.e continuous tapering and focal stenosis -under synthetic scanner noise. A global inverse optimization approach utilizing Dual-Tikhonov regularization was deployed to stably invert the ill-posed transit time integral, actively penalizing high-frequency numerical ringing while preserving structural curve stiffness. The computational sim-ulations successfully recovered ground-truth point-wise velocities, accurately tracking gradual hemodynamic accelerations and sharp stenotic jets. This theoretical framework provides a robust mathematical proof-of-concept that quantitative, localized functional hemodynamic metrics can be extracted from standard structural MRA imaging, estab-lishing a foundation for advanced flow quantification without requiring additional scan time.

Bread People, what did I do wrong?
While the photos look nice, this loaf turned out just slightly wet/gummy feeling.
I did wait well over an hour before slicing. I have some ideas.
This recipe was about 94% hydration, as opposed to the 84% hydration I've been using.
Also, this was in a 2 quart dutch oven and I wonder if it is just too small for this loaf. (Over 740 grams)
Oh, I also did a two-day cold ferment.
(I guess I changed a lot of variables at…
