Query-Limited Community Recovery in Stochastic Block Models

Announce Type: new Abstract: We study exact community recovery in the two-community stochastic block model on $n$ vertices under limited and noisy access to network data. The learner may query a noisy neighborhood oracle that reveals each true neighbor of a queried vertex independently with fixed probability and never returns non-neighbors, subject to a finite query budget. We consider both oracle-only access and a combined model where the learner also observes a single subsampled copy of...

NetKV: Network-Aware Decode Instance Selection for Disaggregated LLM Inference

Announce Type: new Abstract: Disaggregated LLM inference forces the KV cache to traverse the datacenter network before decoding begins, so transfer time enters directly into the Time to First Token (TTFT) budget. Current schedulers route on compute load and prefix-cache locality alone, ignoring the topological distance and dynamic congestion between prefill and decode instances.

Signals and Spoils: Speculative Oracle Extractable Value in the Era of Cross-Chain Interoperability

Announce Type: new Abstract: A new form of Maximal Extractable Value (MEV), termed speculative MEV, has emerged across Layer-2 blockchains. Unlike Ethereum mainnet, many Layer-2 systems lack a public mempool, forcing extraction strategies to become probabilistic: searchers emit multiple identical transactions hoping to capture an opportunity first. This generates substantial transaction spam, increasing fees and wasting block space.

Software stocks just passed a big milestone

Could it be "SaaSpocalypse Never?" Software stocks are surging back from an artificial intelligence-driven sell-off that saw the group shed almost 40% from highs last year, rallying about 6% Monday in a surge that brought the year-to-date performance in the iShares Expanded Tech-Software Sector ETF (IGV) into positive territory for the first time. The fund is now less than 9% below its all-time high from September after a 44% rally off its April low.

Analysis:Software stocks bounce back - now comes the hard part

Analysis:Software stocks bounce back - now comes the hard part June 3 : Software stocks have rebounded from a punishing selloff as investors are betting that AI may boost the sector rather than leaving it for dead. The iShares Expanded Tech-Software Sector ETF has surged nearly 42 per cent from its April low, turning fears that AI would rip the heart out of the industry into hopes that software firms will enlist AI as a valuable ally. The software ETF is down under 2 per cent for 2026 after...

TN-SHAP-G: Graph-Structured Tensor Network Surrogates for Shapley Values and Interactions

arXiv:2606.01540v1 Announce Type: new Abstract: Shapley values are a widely used tool for attributing importance and interactions among input variables in black-box models, but their computation involves a function defined over an exponentially large space of subsets. We propose TN-SHAP-G, a framework that exploits structure in graph-structured inputs to compute Shapley values and higher-order interaction indices efficiently. Given a predictor and a fixed masking scheme, TN-SHAP-G learns a...

Reachability for Low-Thrust Trajectories via Maximum Initial Mass

Announce Type: replace Abstract: Reachability analysis plays a central role in low-thrust spacecraft trajectory optimization by identifying which target states can be achieved under constraints on time, thrust, and propellant. Classical approaches construct reachable sets by solving many optimal control problems over grids of terminal states, requiring extensive forward simulations with fixed initial conditions. While effective, this approach is computationally expensive and becomes...

Hierarchical Forecast Reconciliation for Urban Rail Transit Demand Prediction under Operational Disruptions

Announce Type: new Abstract: Accurate and coherent passenger demand forecasting is essential for Urban Rail Transit (URT) operations. Passenger demand has a hierarchical structure in which origin-destination (OD) flows aggregate to station-level inflows and outflows through conservation constraints. In practice, station-level and OD-level forecasts are often generated independently, producing incoherent predictions that violate these constraints and introduce inconsistencies into operational...

US broadcaster CBS fires 60 Minutes’s Scott Pelley after clash with bosses

US broadcaster CBS fires 60 Minutes’s Scott Pelley after clash with bosses Veteran journalist’s dismissal comes after he reportedly accused management of ‘murdering’ influential news programme. US broadcaster CBS has fired Scott Pelley, a longtime correspondent for its 60 Minutes programme, after he reportedly said Editor-in-Chief Bari Weiss was “murdering the show” and accused its new producer of having “slender qualifications” for the job. The firing on Tuesday deepened the turmoil at the...
