Previous studies have explored the relationship between termite branch tunnel geometry and foraging efficiency in a model simulation in which foraging efficiency, γ, for two termite species, Coptotermes formosanus Shiraki and Reticulitermes flavipes (Kollar) (Isoptera: Rhinotermitidae), was investigated in response to two variables, the probability of tunnel branching (P(branch)) and the probab...

The tree-like architecture of the mammary gland is generated by branching morphogenesis, which is regulated by many signals from the microenvironment. Here we examined how signaling downstream of phosphoinositide 3-kinase (PI3K) regulates different steps of mammary branching using three-dimensional culture models of the mammary epithelial duct. We found that PI3K was required for both branch in...

Using correlated live-cell imaging and electron tomography we found that actin branch junctions in protruding and treadmilling lamellipodia are not concentrated at the front as previously supposed, but link actin filament subsets in which there is a continuum of distances from a junction to the filament plus ends, for up to at least 1 μm. When branch sites were observed closely spaced on the sa...

2 Matroid Theory 3 This paper explores the connection between network coding and matroid theory, 4 a branch of mathematics that generalizes linear algebra and graph theory. ABSTRACT | Networks derived from matroids have played a 7 fundamental role in proving theoretical results about the limits 8 of network coding. In this tutorial paper, we review many con-9 nections between matroids and netwo...

PHS/DECT networks are “micro-cellular” radio access systems. Unlike cellular or 3G (third-generation) wireless networks they don’t require comprehensive, expensive supporting network architectures. Instead they inter-work with existing systems, such as PBXs (private branch exchanges), the PSTN (public switched telephone network), cellular networks, and ISDN (integrated services digital network)...

There are many challenging problems in the person re-identification (ReID) task, such as occlusion and scale variation. Existing works usually tried to solve them by employing a one-branch network. This network needs be robust various problems, which makes this overburdened. paper proposes divide-and-conquer ReID task. For purpose, we employ several self-supervision operations simulate differen...

The paper applies an economic model of a competitive market for retail banking services to generate insights into the following relevant questions. Is the cost structure of electronic distribution systems sufficient to justify choosing the Kiosk/PC Banking distribution strategy? That is, is it reasonable that market pressures and technological advances will allow banks to virtually eliminate br...

Content delivery is an increasingly dominating functionality of the Internet, and continuously poses significant pressures on the networking infrastructure as well as content providers. As a general mechanism to improve efficiency, caching has been used in several approaches; e.g., CDNs, caching proxies, and Redundancy Elimination (RE). In this paper, we propose a new caching paradigm called Br...
