TL;DR: The Amakomanak site (AMR-00095) dates around 7500 BC and is located in the Noatak National Preserve in northwestern Alaska and presents an important microblade component (microblade cores, core tablets and microblades) made of local chert as discussed by the authors.
Abstract: The Amakomanak site (AMR-00095), dated around 7500 BC, is located in the Noatak National Preserve in northwestern Alaska and presents an important microblade component (microblade cores, core tablets, and microblades) made of local chert. During the late Pleistocene and the early Holocene, microblade technology is widespread in central Alaska, dominated by Campus-style microblade cores (wedge-shaped microblade cores). The Amakomanak assemblage is primarily composed of larger prismatic microblade cores, similar to assemblages from other northwestern Alaskan sites compared here. This paper argues that raw material available in each area may have played a major role in the different microblade core variants described. Indeed, raw material availability in the northwestern region could be one of the major reasons behind the production of larger prismatic cores, as opposed to central Alaska Campus-style cores usually made on smaller river cobbles. The paper also presents the results of a morphometric analysis of microblade cores and microblades from the Amakomanak site, comparing the data to both experimentally derived data sets on microblade-flaking modes, as well as other microblade assemblages in Alaska and Siberia.

TL;DR: A continuous excess demand function is non-positive for some semi-positive price vector, as soon as all commodities cannot be simultaneously in excess demand as discussed by the authors, i.e., all commodities are simultaneously in negative demand.

TL;DR: The Barankin bound is derived when the multiplicative noise is complex-valued and non-circular enough and the Cramer-Rao bound is not a tight bound anymore and has to be replaced with the so-called Baranksin bound which is tighter but more complicate.
Abstract: We focus on harmonic retrieval in multiplicative and additive noise. At low SNR, Maximum-Likelihood based estimate does not reach the Cramer-Rao bound. Actually, at low SNR, the Cramer-Rao bound is not a tight bound anymore and has to be replaced with the so-called Barankin bound which is tighter but more complicate. In this paper, we derive the Barankin bound when the multiplicative noise is complex-valued and non-circular. We observe that the Barankin bound is much more greater than the Cramer-Rao bound, especially when the multiplicative noise is not non-circular enough.
