Mammalian navigation is thought to depend on an internal map of space consisting of functionally specialized cells in the hippocampus and the surrounding parahippocampal cortices. Basic properties of this map are present when rat pups explore the world outside of their nest for the first time, around postnatal day 16-18 (P16-P18). One of the first functions to be expressed in navigating animals...

Node compromise is a serious threat in wireless sensor networks. Particular in networks which are organized in clusters, nodes acting as cluster heads for many cluster nodes are a valuable target for an adversary. We present two efficient hardware-based attestation protocols for detecting compromised cluster heads. Cluster heads are equipped with a Trusted Platform Module and possess much more ...

In Trec-2002, we participated in the Web Trec (named page finding task). There are two kinds of information that can be used while finding the expected page, content information and link information. We exploited both of them. That is to say, our system is content-based and link-based. As to link information, we only used anchor text and connections, and topology between pages is ignored. We su...

This paper introduces a novel anchor design to support anchor-based face detection for superior scale-invariant performance, especially on tiny faces. To achieve this, we explicitly address the problem that anchor-based detectors drop performance drastically on faces with tiny sizes, e.g. less than 16 × 16 pixels. In this paper, we investigate why this is the case. We discover that current anch...

Anchor text has been considered as a useful resource to complement the representation of target pages and is broadly used in web search. However, previous research only uses anchor text of a single snapshot to improve web search. Historical trends of anchor text importance have not been well modeled in anchor text weighting strategies. In this paper, we propose a novel temporal anchor text weig...

Lernaea cyprinacea, commonly known as anchor worm, is a cosmopolitan invasive copepod that parasitizes wide variety of freshwater fish, including several native and endemic species the Iberian Peninsula (Sánchez-Hernández 2017), like Squalius alburnoides from Guadiana River basin depicted in photograph, with 3 different individuals attached. Anchor worm was introduced to Iberia Asia 1970s (Simo...
