Abstract: The New Keynesian example of Beraja (2023) is not identified at its printed calibration: more than one structure satisfies every condition of its identification step. Two of the paper's six identifying restrictions coincide on equilibrium equations consistent with the printed reduced form, leaving eleven conditions to determine an equation's twelve coefficients. The note derives the rank condition the identification step requires, computable from the reduced form and the restrictions alone. The note also documents and corrects a misprint in the paper's counterfactual display. A one-clause amendment to the paper's Theorem 1 restores its conclusion.

Abstract: Hydrogen Lyman-alpha (Ly$\alpha$) is a prominent emission line from the circumgalactic medium (CGM). Due to its resonant nature, Ly$\alpha$ carries imprints of the physical properties and kinematics of the cold CGM. In particular, CGM rotation can modify the Ly$\alpha$ peak separation, which is often interpreted as a tracer of H I column density. We present 3D Monte Carlo Ly$\alpha$ radiative-transfer simulations in a CGM-like rotating medium and examine how the emergent spectra depend on rotational velocity ($V_{\rm rot}$), H I column density ($N_{\rm HI}$), viewing angle, clumpiness, and intrinsic source width. We find that rotation broadens the integrated spectra and increases the peak separation, with the strongest viewing-angle dependence when rotational Doppler shifts dominate over frequency diffusion. At high $N_{\rm HI}$, numerous scatterings reduce the sensitivity of integrated spectra to rotation, producing a degeneracy between $V_{\rm rot}$ and $N_{\rm HI}$. Consequently, Ly$\alpha$ peak separation alone can overestimate $N_{\rm HI}$ in a rotating medium. Spatially resolved halo spectra provide a clearer diagnostic: opposite sides of the rotating medium show systematic redshifted and blueshifted asymmetries associated with the line-of-sight velocity of the last-scattering gas. Such rotation-driven signatures can also contribute to velocity-map patterns often interpreted in terms of inflow or outflow, highlighting the need to consider rotation in spatially resolved Ly$\alpha$ observations. We further show that the main signatures persist in simple clumpy media, while the halo signatures are largely insensitive to the intrinsic source width. Our results demonstrate that spatially resolved Ly$\alpha$ observation is essential for disentangling CGM rotation from radiative-transfer effects.

This radioactive gas can quietly seep into homes and is linked to 21,000 deaths a year in the U.S. alone
Radon is an invisible radioactive gas linked to lung cancer, especially in smokers. Testing homes is the only way to detect dangerous levels and reduce exposure.

An experimental personalized cancer vaccine from Merck and Moderna showed positive initial results in its first-ever late-stage trial.
The combination regimen met the main study goal of significantly extending the time patients lived without their melanoma returning, compared with Keytruda alone, and also reduced the risk of the cancer spreading to distant parts of the body.
The initial data suggests that the combo could serve as a new treatment option for the deadliest form of sk…

Review of studies on single-use plastics reveals broader circular economy approach is needed
A review of research published in the Interdisciplinary Environmental Review on single-use plastics argues that tackling the waste problem will require a shift from recycling alone to a broader circular economy approach, in which materials are kept in use through reuse, recovery, recycling and redesign.

Integrable curl-force Hamiltonians: bi-Hamiltonian structure, separability, and periodic orbits

Abstract: We investigate Hamiltonian curl-force systems with indefinite kinetic energy. We first reconsider Berry's polynomial Hamiltonian curl-force model, whose numerically observed closed trajectories motivated an integrability conjecture. A Painlev\'e analysis yields a non-principal resonance spectrum, so that the corresponding Laurent series cannot accommodate the required number of arbitrary constants of the general solution. The model therefore fails the standard Painlev\'e test. We then introduce a four-parameter curl-force family and identify the parameter locus on which this system is integrable. We construct a second Hamiltonian, compatible Poisson tensors, separated complex characteristic variables, and a Lax representation. More generally, the separated form yields polynomial integrable curl-force Hamiltonians of arbitrary degree. We also show that the same construction admits a higher time-derivative potentialisation whose free limit is the degenerate Pais-Uhlenbeck oscillator. Finally, we analyse zero-curl invariant reductions and elliptic periodic solutions, and exhibit an isolated periodic orbit outside the integrable regime. This illustrates that closed trajectories alone do not imply Liouville or Painlev\'e integrability.

"The biggest hurdle to adoption is consumer concern about charging infrastructure, Buckberg said. As that infrastructure grows nationally, gaps in charger coverage will narrow.
What will help, Buckberg said, is making charger status and price available so EV drivers can find them in any mapping app. By reducing consumer “range anxiety,” app-data transparency alone could potentially boost sales 6 percent."
