OBJECTIVE We conducted a pilot survey to evaluate breast cancer patients' willingness to participate in a preoperative chemoprevention (ie, window-of-opportunity) study. Design A 27-question written survey was developed and administered to participants. Setting A breast cancer specialty clinic at the University of Wisconsin Hospital and Clinics. Participants 30 adult patients with newly diagnos...

This letter studies the attack detection problem in a data-driven and model-free setting, for deterministic systems with linear time-invariant dynamics. Differently from existing that leverage knowledge of system dynamics to derive security bounds monitoring schemes, we treat cases where dynamics, as well strategy location, are unknown. We fundamental limitations function only observed data wit...

0.1 Proofs of Theorems 4.1, 4.2 & 5.2 Proof of Theorem 4.1: Let bn = pn+ln, where pn = b √ nc. Define a block of observations as Bn(i) = i + bn(0, 1], i ∈ Z. We first divide Rn into non-overlapped blocks of observations. Let Kn = {k ∈ Z : Bn(bnk) ⊂ Rn} represents the index set of all complete blocks Bn(bnk) = bn(k + (0, 1]) lying inside Rn. For each k ∈ Kn, we further divide each block into lar...
