This paper presents design methods for boundary filters for the processing of finite-length signals. In particular, it is shown how vanishing moments can be imposed during the design. Applications are found in segmentation-based audio and shape-adaptive image compression.

Regulatory policy in telecommunications is desperately in need of mid-level theory. There is widespread consensus that regulators should try to promote competition. There is also bitter contention about what this implies for particular industry battles. For example, an industry observer declared, “Competition should be the policy. And code that enables competition should be the rule.” He then w...

Superconductivity has been realized in films of La$_{1-x}$Sr$_x$NiO$_2$. Here we report synthesis and characterization polycrystalline samples La$_{1-x}$Sr$_x$NiO$_3$ La$_{1-x}$Sr$_x$NiO$_2$ ($0\le x\le 0.2$). Magnetization resistivity measurements reveal that are paramagnetic metals exhibit insulating behavior. is not detected bulk The absence superconductivity may be due to the generation hyd...

Crystal growth from anhydrous hydrogen fluoride solutions of M2+ (M=Cu, Ag) and [AuF6]− gave M(AuF6)2 salts Ag). Similar attempts to prepare single crystals the corresponding nickel, zinc magnesium failed. The crystal structure Cu(AuF6)2 consists layers Cu2+ cations connected by anions, thus forming slabs. Only van der Waals interactions exist between adjacent Ag(AuF6)2 a three-dimensional fram...
