Legendre-Gauss-Lobatto Collocation Method for Optimal Control via Polynomial Approximations of Differential Equation Vector Fields
A new method is described for solving optimal control problems using direct collocation at Legendre-Gauss-Lobatto points. The approach of this paper employs a polynomial approximation of the right-hand side vector field of the differential equations and leads to the following important outcomes. First, the first-order optimality conditions of the LGL integral form are derived, which lead to a full-rank transformed adjoint system and novel costate estimate. Next, a derivative-like form of the LG…

A heady throng of tech billionaires, ministers, corporate titans and the king of the Netherlands have convened in Sweden for the 71st Bilderberg meeting
– the publicity-shy annual policy conference that has long sustained conspiracy theorists
– hosted this year by the fabulously wealthy Wallenberg family.
The four days of transatlantic talks are taking place at the swanky Grand hotel,
which is owned, like so much else in Sweden, by the Wallenbergs.
The Swedis…

Role of topotactic hydrogen in Superconductivity of Infinite-layer Nickelate NdNiO$_{2}$: A first-principles and variational Monte Carlo study
Employing combination of first-principles calculations, low-energy model construction, and variational Monte Carlo solution of the ab-initio derived Hubbard model, we study the effect of hydrogenation in the electronic structure and superconducting properties of infinite-layer nickelate, NdNiO$_2$. We find that the introduction of hydrogen at the apical oxygen vacancy position strongly influences the Wannier function corresponding to the effective interstitial orbital at the Ni site bound to th…

Minnesota Gov. Tim Walz says Democrats need to take a page from Donald Trump’s own playbook.
“Maybe it’s time for us to be a little meaner,” the former vice presidential hopeful said during a speech at the South Carolina Democratic Party’s annual convention in Columbia, South Carolina.
“Maybe it’s time for us to be a little more fierce because we have to ferociously push back on this.”
“When it’s a bully like Donald Trump, you bully the s--t out of him,” Walz added

Walz Tells Dems to ‘Bully the S**t’ Out of Trump or Risk Becoming ‘Roadkill’
The former vice presidential candidate doled out harsh words for both the president and his own party.
