But she was denied that care twice as she feared for her life – and, after the delay in care, she lost her fertility, she says in a new lawsuit filed Monday.
Adjacency Spectral Radius Under Laplacian Sparsification: Deterministic and Probabilistic Bounds
arXiv:2606.07459v1 Announce Type: cross Abstract: Spielman-Srivastava spectral sparsification preserves Laplacian quadratic forms to within (1 +/- epsilon), but does not directly control the adjacency spectral radius lambda_1, which governs the NIMFA epidemic threshold and arises in spectral clustering. We prove |lambda_1(A_H) - lambda_1(A_G)| <= epsilon(2 Delta - lambda_1) deterministically, with a sharp epsilon*lambda_1 bound for reweighting sparsifiers via Perron-Frobenius monotonicity....
Sources: Red Wings captain Larkin requests trade
Red Wings captain Dylan Larkin has requested a trade from Detroit, sources told ESPN on Thursday. Sportsnet was the first to report the news, which should send shock waves across the NHL ahead of the summer draft and free agency period. Larkin has a full no trade clause in his contract through next season, meaning he will have control over his destination.
Spectral Methods in Microeconomics
arXiv:2502.12309v2 Announce Type: replace-cross Abstract: Matrices often appear in formal models of social and economic behavior, especially models involving networks. Such models are used to study subjects ranging from opinion dynamics to pollution-mitigation negotiations to the regulation of large marketplace platforms. Matrices are used to capture the focal economic structure in each case.
