Tertiary Tides with Eccentric Orbits
Within hierarchical triple stellar systems, there exists a tidal process unique to them, known as tertiary tides. In this process, the tidal deformation of a tertiary in a hierarchical triple drains energy from the inner binary, causing the inner binary's orbit to shrink. Previous work has uncovered the rate at which tertiary tides drain energy from inner binaries, as a function of orbital and tidal parameters, for hierarchical triples in which the orbits are all circular and coplanar. However,…

Multi-Orbital Charge Transfer into Nonplanar Cycloarenes Revealed with CO-Functionalized Tips
On-surface synthesis has allowed for the tuneable preparation of numerous molecular systems with variable properties. Recently, we demonstrated the highly selective synthesis of kekulene (>99%) on Cu(111) and isokekulene (92%) on Cu(110) from the same molecular precursor (Ruan et al., Angew. Chem. Int. Ed. 2025, e202509932). Scanning tunneling microscopy with CO-functionalized tips can identify the single molecules on the basis of their geometric structure at a low coverage on Cu(110), but it a…

Forcing a unique minimum spanning tree and a unique shortest path
A forcing set $S$ in a combinatorial problem is a set of elements such that there is a unique solution that contains all the elements in $S$. An anti-forcing set is the symmetric concept: a set $S$ of elements is called an anti-forcing set if there is a unique solution disjoint from $S$. There are extensive studies on the computational complexity of finding a minimum forcing set in various combinatorial problems, and the known results indicate that many problems would be harder than their class…

»Datenleck bei Sonicwall — Alle Cloud-Backups von Firewalls gestohlen:
Hieß es zunächst, es seien nur wenige Prozent der Sicherungsdaten betroffen, wird nun klar: Es sind tatsächlich 100 Prozent - Admins sollten handeln.«
Ach du heilige $cheibenkleister! Backups sind doch eigentlich genau deswegen verschlüsselt und einmal geklaut ist es einfach nicht mehr in Sicherheit. Dies von einer IT-Security Firma.

Oh no. So sad to hear of Keith McIvor / JD Twitch's far too early death (on my birthday of all days 😪).
Optimo has been such an important influence on me and just last week a friend and I talked about what a wonderful time we had with him when we once invited him to our club for a set. RIP. What a loss.

Good Morning #Canada
Many people, that includes you, are worried about #Skynet assuming control of all military systems, but what happens when it starts harvesting our crops? Canadian agricultural scientists are blindly charging ahead in their efforts to fill our farms with robots. It started with self-driving tractors pulling conventional equipment and evolved to fully autonomous vehicles that plow, plant, fertilizer, weed, and harvest. Organic farming is seeing the biggest benefits as robots can hand weed 2 hectares per day, eliminating herbicides.... and farm workers. Almost 15% of Canada’s dairy farms use robotic milking cubicles where cows enter when they need milking, with no cold human hands involved. IMO, using robots to replace hard back breaking labour or tedious driving of equipment up and down a farm field is a good use of technology. But I hope the tech is not priced out of the reach of small farms.
