 The Balian-Low theorem (BLT) is a key result in time-frequency analysis, originally stated by Balian and, independently, by Low, as: If a Gabor system $\{e^{2\pi imbt} \, g(t-na)\}_{m,n \in \mbox{\bf Z}}$ The main purpose of this paper is to give a procedure to "mollify" the low-pass filters of a large number of Minimally Supported Frequency (MSF) wavelets so that the smoother functions obtained in this way are also low-pass filters for an MRA. This phenomena is related to the invariant cycles under the transformation We also give a characterization of all low-pass filters for MSF wavelets. The main purpose of this paper is to give a procedure to "mollify" the low-pass filters of a large number ofMinimally Supported Frequency (MSF) wavelets so that the smoother functions obtained in this way are also low-pass filters for an MRA. We also give a characterization of all low-pass filters for MSF wavelets. 更多

 Lower degree bounds for modular invariants and a question of I. Lower bounds for Kazhdan-Lusztig polynomials from patterns We give a lower bound for the values Px,w(1) in terms of "patterns". Our lower bound comes from applying a decomposition theorem for "hyperbolic localization" [Br] to this torus action. An important property of this matrix is that the maximum and minimum eigenvalues are equal (in some sense) to the upper and lower frame bounds. 更多

 The main theme of this paper is that many of the remarkable properties of invariant theory pertaining to semisimple Lie algebras carry over to parabolic subalgebras even though the latter have less structure. 32% or less, have been evaluated in a full panel of 60 human cancer cell lines over a 5-log dose range at the National Cancer Institute. All the derivatives were significantly less irritating to the gastric mucosa than the parent drug. Furthermore, it is proved that the minimum of the total number of bends in an at most single-bend embedding of a cubic graph of ordern is less than or equal to 0.5n+1. ×Cdn(d1≥2.1≤n) has a rout-ing such that at most one intermediate node is needed to ensure transmission of messages among all non-faulty nodes so long as the number of faults is less than n. 更多

 Al-Baali, we get the global convergence of the Fletcher-Reeves algorithm with a low-accuracy inexact linesearch. The accelerometer has a high sensitivity of 6.91 kHz/g, a low temperature coefficient, and a simple fabrication process. Compared with the gradient vector flow snake, this new model has a low computational cost. It shows that this method can rapidly acquire good performance at a low SNR. A low pass filter was designed to filter the carry waves of the sweeping source. 更多
