Covert Communication over Physically-Degraded Alarm Two-Way Channels
We study covert communications over binary-input discrete memoryless alarm two-way channels, in which two users interact through a two-way channel and attempt to hide the presence of their communication from an eavesdropping receiver. The alarm two-way channel is one in which simultaneous transmissions by both users trigger an alarm at the eavesdropper, which captures the challenges and opportunities of cooperation beyond interference management. In particular, by characterizing the covert capa…

On the ring of cooperations for real Hermitian K-theory
Let kq denote the very effective cover of the motivic Hermitian K-theory spectrum. We analyze the ring of cooperations $π^\mathbb{R}_{**}(\text{kq} \otimes \text{kq})$ in the stable motivic homotopy category $\text{SH}(\mathbb{R})$, giving a full description in terms of Brown--Gitler comodules. To do this, we decompose the $E_2$-page of the motivic Adams spectral sequence and show that it must collapse. The description of the $E_2$-page is accomplished by a series of algebraic Atiyah--Hirzebru…

Will do a proper #FieldDiary tomorrow but suffice to say, today went even better than hoped. Instruments behaved, weather cooperated our local hunter friend got us smoothly into the field. Looking forward to seeing what it all means now...

Going through my feeds this morning, I see a bunch of suspicious, poorly written English reports in Middle Eastern publications that have never shown up on my radar screen before that tell of cyberattacks by variously named Iranian-related "hacktivist" groups.
