Extracting Alternative Solutions from Benders Decomposition
We show how to extract alternative solutions for optimization problems solved by Benders Decom- position. In practice, alternative solutions provide useful insights for complex applications; some solvers do support generation of alternative solutions but none appear to support such generation when using Benders Decomposition. We propose a new post-processing method that extracts multiple optimal and near-optimal solutions using the cut-pool generated during Benders Decomposition. Further, we pr…

Republicans grapple with voter frustration over rising health care premiums
By Sarah Ferris, Manu Raju, CNN (CNN) — Anxiety is rising among congressional Republicans that their party has no plan to address a critical health care deadline this fall that will result in spiking costs for millions of Americans – the issue at the heart of the deepening government shutdown crisis. And some of those GOP members are offering a stark warning to their own leaders: Doing nothing could cost them their full control of Congress in ne…

Can GRB 250702B be explained as the tidal disruption of a white dwarf by an intermediate mass black hole? Yes
GRB 250702B is a unique astrophysical transient characterised by its nature as a repeating gamma-ray trigger. Its properties include possible periodicity in its gamma-ray light curve, an X-ray counterpart that rose prior to the gamma-ray outbursts and faded quickly, and radio and infrared counterparts. These features are difficult to reconcile with most models of high energy transients but we show that they are compatible with a white dwarf bound to an intermediate mass black hole that is tidal…

JWST Spectroscopy of GRB 250702B: An Extremely Rare and Exceptionally Energetic Burst in a Dusty, Massive Galaxy at $z=1.036$
We present follow-up observations of the day-long, repeating GRB 250702B with the Near Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST). Through the identification of narrow hydrogen emission lines at a consistent redshift of $z = 1.036 \pm 0.004$, we calibrate the distance scale, and therefore the energetics, of this unique extragalactic transient. At this distance, the resulting $γ$-ray energy release is at least $E_{γ,\rm iso} = 2.2 \times 10^{54}$\,erg. We fi…
