Sheinbaum says Mexico declines Trump's 'Board of Peace' invite
'The next stage of the Gaza genocide has begun' How important is the Rafah crossing reopening? Sheinbaum says Mexico declines Trump's'Board of Peace' invite NewsFeed Sheinbaum says Mexico declines Trump's'Board of Peace' invite Mexican President Claudia Sheinbaum said she has turned down an invitation from Donald Trump to join his "Board of Peace," citing a lack of Palestinian participation as a recognised state. She will "probably" be sending an observer to Thursday's meeting, however.

Why Israel's annexation threatens Jordan

Why Israel's annexation threatens Jordan NewsFeed Why Israel's annexation threatens Jordan Israel's plans to claim parts of the occupied West Bank as'state property' is raising concerns in neighbouring Jordan. Strategists warn that the move could be the final prelude to the'alternative homeland' scenario,' as Julide Ayger explains.

Meta and Other Tech Companies Ban OpenClaw Over Cybersecurity Concerns
Security experts have urged people to be cautious with the viral agentic AI tool, known for being highly capable but also wildly unpredictable. Last month, Jason Grad issued a late-night warning to the 20 employees at his tech startup. "You've likely seen Clawdbot trending on X/LinkedIn. While cool, it is currently unvetted and high-risk for our environment, he wrote in a Slack message with a red siren emoji. "Please keep Clawdbot off all company hardware and away from work-linked accounts." Grad isn't the only tech executive who has raised concerns to staff about the experimental agentic AI tool, which was briefly known as MoltBot and is now named OpenClaw. A Meta executive says he recently told his team to keep OpenClaw off their regular work laptops or risk losing their jobs. The executive told reporters he believes the software is unpredictable and could lead to a privacy breach if used in otherwise secure environments. He spoke on the condition of anonymity to speak frankly.
Logical Characterizations of Recurrent Graph Neural Networks with Reals and Floats
In pioneering work from 2019, Barcelรณ and coauthors identified logics that precisely match the expressive power of constant iteration-depth graph neural networks (GNNs) relative to properties definable in first-order logic. In this article, we give exact logical characterizations of recurrent GNNs in two scenarios: (1) in the setting with floating-point numbers and (2) with reals. For floats, the formalism matching recurrent GNNs is a rule-based modal logic with counting, while for reals we use a suitable infinitary modal logic, also with counting. These results give exact matches between logics and GNNs in the recurrent setting without rel-ativising to a background logic in either case, but using some natural assumptions about floating-point arithmetic. Applying our characterizations, we also prove that, relative to graph properties definable in monadic second-order logic (MSO), our infinitary and rule-based logics are equally expressive. This implies that recurrent GNNs with reals and floats have the same expressive power over MSO-definable properties and shows that, for such properties, also recurrent GNNs with reals are characterized by a (finitary!)
Appendix for "Episodic Multi-Task Learning with Heterogeneous Neural Processes "
Appendix for "Episodic Multi-T ask Learning with Heterogeneous Neural Processes" In this section, we list frequently asked questions from researchers who help proofread this manuscript. As shown in Table 1, we use "Heterogeneous tasks" to distinguish the different branches of multi-task Meanwhile, "Episodic training" is used to describe the data-feeding strategy. Thus, "Heterogeneous tasks" is not available here (-). In episodic multi-task learning, we restrict the scope of the problem to the case where tasks in the same episode are related and share the same target space. This also implies that tasks with the same target space are related.
