#running slow is hard but my fitness is such that it requires a rebuild of the foundation. Trying to stay in HR2 means a decent amount of walking interspersed. I don’t love it, but it’s necessary.
I have a much more open schedule now, so I should be able to get out and run regularly. The trick will be staying patient and trusting the process.

Bipartite Turán numbers via edge-gluing
In 1984, Erdős and Simonovits asked the following: given a bipartite graph $H$, do there exist constants $0 \leq α< 1$ and $β, C > 0$ such that any graph $G$ on $n$ vertices and $pn^2\geq C n^{1+ α}$ edges contains at least $βn^{\mathrm{v}(H)} p^{\mathrm{e}(H)}$ copies of $H$? We show that edge-gluing preserves the satisfiability of this conjecture under some mild symmetry conditions. Namely, if two graphs $H_1$ and $H_2$ satisfy this conjecture, and if furthermore, gluing them along a f…

Computational Complexity of Model-Checking Quantum Pushdown Systems
In this paper, we study the problem of model-checking quantum pushdown systems from a computational complexity point of view. We arrive at the following equally important, interesting new results: We first extend the notions of the {\it probabilistic pushdown systems} and {\it Markov chains} to their quantum analogues and investigate the question of whether it is necessary to define a quantum analogue of {\it probabilistic computational tree logic} to describe the probabilistic and branching-…

Shield AI has emerged as a lead contender in the increasingly crowded race against competitors like Anduril and AeroVironment
to outfit the U.S. military with killer drones.
The $5 billion-valued startup, founded in 2015 by brothers Ryan and Brandon Tseng,
sells a suite of hardware and products, including autonomous piloting software that has been used to fly fighter jets.
In March, it raised $240 million in a funding round led by Korean conglomerate Hanwha and Amer…

Global well-posedness of the Majda-Biello system in the resonant case on the real line
We study the Cauchy problem for the following Majda-Biello system in the case $α=4$, which has the most significant resonance effect, on the real line. \[ \left\{ \begin{array}{l} u_{t} + u_{xxx} = - v v_x, v_{t} + αv_{xxx} = - (uv)_{x}, (u,v)|_{t=0} = (u_0,v_0) \in H^{s}(\mathbb{R}) \times H^{s}(\mathbb{R}), \end{array} \right. \quad x \in \mathbb{R}, \, t \in \mathbb{R}. \] For Sobolev regularity $s\in[\frac34, 1)$, we establish the global well-posedness by refining the I-method.…
