Sankey scoffs at notion of SEC-B1G super league
Southeastern Conference commissioner Greg Sankey said there's no talk of a merger with the Big Ten and called the notion that the SEC wants to form a super league -- the specter of which is being leveraged by lawmakers as a central threat to the future of college sports -- as "not consistent with the truth." Sankey, in an interview Friday on ESPN's "The Paul Finebaum Show," outlined the reasons the SEC does not support a bipartisan bill introduced last week in Congress that would regulate a...
Putin's word of caution on India-China ties; rejects notion that Pakistan is under Beijing's control
Russian President Vladimir Putin on Thursday said Moscow would not interfere in the "delicate" relationship between India and China, expressing confidence that Prime Minister Narendra Modi and Chinese President Xi Jinping were working to resolve outstanding issues of mutual interest, including the long-running border dispute. Speaking during an interaction with media in St Petersburg, Putin said Russia maintained strong ties with both New Delhi and Beijing and saw no reason to intervene in...
Identification of novel enolase negative Segatella copri subspecies supports notion of Segatella copri speciation via alternative phosphoenolpyruvate synthesis pathways
Segatella copri is characterised as a prominent glycolytic plant-based fiber utiliser within the human gut. My recent work has introduced a new interpretation of the positive impacts of plant-based polysaccharides on S. copri, as a significant negative relationship between S. copri and Blautia spp. was identified. The high rate of electron donor consumption by Blautia spp. indicated that competition for the electron donors, formate, ferredoxin and fumarate, could be the route of the negative...
How did the notion of ‘two-tier policing’ evolve, and does it really exist?
Data discredits claims reawakened by the death of Henry Nowak that UK police actions disadvantage white peopleThe US government has joined criticism of alleged two-tier policing in the UK in the wake of Henry Nowak’s murder. How did the term enter the mainstream, and is there any basis for the claim?
Simultaneous EF1 and approximate MMS allocations for submodular valuations
Announce Type: new Abstract: There are two common classes of fairness notions that are considered when allocating $m$ indivisible items to $n$ agents of equal entitlements. One is that of share-based fairness notions, with the maximin share (MMS) and its relaxations to $\rho$-MMS being prominent representatives of this class. The other is that of comparison-based fairness notions, with envy-freeness (EF) and its relaxations such as EF1 being prominent representatives of this class.
Revisiting Diameter in Directed Graphs
arXiv:2606.08217v1 Announce Type: new Abstract: The reachability diameter ($\mathrm{ReachDiam}$) of a directed graph is the maximum distance over all pairs $u,v$ where $v$ is reachable from $u$. This notion is present in the definition of shortcut sets, and the name was recently coined in that context by Haeupler, Jiang, and Saranurak [SOSA 2026]. While this is a very natural notion of diameter in directed graphs, and especially DAGs, it is so far not computationally explored. Other...
Extending Fair Null-Space Projections for Continuous Attributes to Kernel Methods
arXiv:2511.03304v2 Announce Type: replace Abstract: With the on-going integration of machine learning systems into the everyday social life of millions the notion of fairness becomes an ever increasing priority in their development. Fairness notions commonly rely on protected attributes to assess potential biases. Here, the majority of literature focuses on discrete setups regarding both target and protected attributes.
Towards Non-Monotonic Entailment in Propositional Defeasible Standpoint Logic
Announce Type: new Abstract: Recent work in defeasible reasoning has seen notions of preferential semantics and entailment in the style of Kraus et al. applied to modal logics. However, work in this field has focussed primarily on satisfiability checking, and monotonic notions of entailment, which may be inferentially weak. One particular modal logic where this has been introduced is propositional standpoint logics, where modalities can express the views of different viewpoints.
Irreducibility of Semigroup Morphisms
arXiv:2603.15177v2 Announce Type: replace Abstract: We introduce and study the notion of irreducibility of semigroup morphisms over a finite alphabet. Given an alphabet $\Sigma$, a morphism $\varphi:\Sigma^+\rightarrow\Sigma^+$ is irreducible if any factorisation $\varphi=\psi_2\circ\psi_1$ can only be satisfied if $\psi_1$ or $\psi_2$ is a trivial morphism; otherwise, $\varphi$ is reducible. This definition provides a notion of primality in the endomorphism monoid of the free semigroup -- a...
How To Track Qubits Through Space and Time (Or: Sailing in a Quantum Boat)
Announce Type: cross Abstract: While quantum position verification aims to certify a prover's location using quantum information, existing security definitions only guarantee that part of the successful adversarial party is in the claimed location. This leaves open the possibility that a distributed team of adversaries can jointly simulate a prover in a way that defeats the intended meaning of ``being at a location'' in position-based cryptography. We introduce stronger notions of position...
