Well-Posedness and Efficient Algorithms for Inverse Optimal Transport with Bregman Regularization
This work analyzes the inverse optimal transport (IOT) problem under Bregman regularization. We establish well-posedness results, including existence, uniqueness (up to equivalence classes of solutions), and stability, under several structural assumptions on the cost matrix. On the computational side, we investigate the existence of solutions to the optimization problem with general constraints on the cost matrix and provide a sufficient condition guaranteeing existence. In addition, we propose…

Os americanos celebram a 2 de janeiro o dia nacional da ficção científica, comemorando o nascimento do Asimov. Sendo o Asimov quem é, a coisa até se podia tornar facilmente internacional.
Cš em Portugal não temos ninguém suficientemente destacado no imaginšrio popular para servir como inspiração para um dia semelhante. O que mais se aproxima disso é o Barreiros, mas esse não só estš vivo (estas homenagens costumam ser póstumas) como estš também MUITO longe de ter o destaque do Asimov.<…

Speaking to a room full of generals and admirals late last month, Hegseth derided
“stupid rules of engagement,”
and urged those assembled to get on board with his vision to
“untie the hands of our war fighters.”
He also said he wanted to raise the bar for troops to be investigated for misconduct.
“The rule of law at DoD has been under attack since day one of this administration,”
one of the current JAGs told CNN.
“There is a real dismissiveness of la…

How the Pentagon sidelined lawyers while testing the legal limits of military action
For weeks earlier this year, the Army’s top uniformed lawyer had been raising legal concerns inside the Pentagon about some of the new policies being rolled out dictating how the military can be used and staffed.

At the first SF Transit Riders member assembly! Plan is to hold these quarterly to update members, hear feedback and let members initiate projects. #sfpol

Everywhere I turn, I stumble over stories - different in details, but similar in implications - of society in decay. These include rapid growth in student food bank use, spiking anxiety among kids, random acts of aggression on public transit, rejection of expertise during crises of health, homelessness, democracy, etc, and on and on. These stories are always accompanied by hand-wringing over cause and remedy, but somehow state provision of financial resources only rarely comes up. Funny that…

Asymptotically large free semigroups in Zariski dense discrete subgroups of Lie groups
Let $G$ be a connected algebraic semisimple real Lie group with finite center and no compact factors, and let $Γ$ be a Zariski dense discrete subgroup of $G$. We show that $Γ$ contains free, finitely generated subsemigroups whose critical exponents are arbitrarily close to that of $Γ$. Furthermore, these subsemigroups are Zariski dense in $G$ and $P$-Anosov in the sense of Kassel--Potrie. This shows that no gap phenomenon holds for critical exponents of discrete subsemigroups of Lie groups, …

Scalability and asymptotic adjunction
In this paper, we introduce relative Roe functors and show that for every pair of scalable proper metric spaces, the functor of continuous functions and the relative Roe functor, both associated with this pair, are asymptotically adjoint. While this asymptotic adjunction is weaker than the genuine one, it retains sufficient categorical properties to be intuitive and useful in applications. These results can be used to provide an unsuspended description of the Connes-Higson $E$-theory, establish…

I'm sure it's the nostalgia speaking but I do have fond memories of cutting my teeth writing assembly to push pixels and abuse the hardware. An era when the entire annotated listing for TOS was in the back of a book and you could read and understand most of it.

The painter Henri Rousseau
(1844–1910)
famously never left France;
He concocted his fantastical jungles from visits to the botanical gardens in Paris,
images in books and taxidermized specimens in natural history museums,
and a teeming visual imagination.
The results are on view in a mesmerizing exhibition,
“Henri Rousseau: A Painter’s Secrets,”
at the Barnes Foundation in Philadelphia until Feb. 22.
These works haven’t been assembled …

The Barnes Foundation
A landmark exhibition of paintings by the self-taught artist Henri Rousseau debuts at the Barnes Foundation in fall 2025.
