Multi-core chip architectures are becoming mainstream, permitting increasing on-chip parallelism through hardware support for multithreading. Fine-grain synchronization is essential to the effective utilization of the capacity provided by future high-performance multi-core architectures. However, there are also new challenges realizing such fine-grain synchronization in large-scale multi-core c...

This paper presents the design and implementation of a communication protocol for the IBM Cyclops-64 (C64) supercomputer system to enable reliable data transfer between the two major components of a C64 system: the C64 host system (also called C64 frontend) and the C64 compute engine (also called C64 back-end). The building block of C64 compute engine (C64 chip) employs a multi-core-on-a-chip a...

The role of specific axonal tracts for the guidance of growth cones was investigated by examining axonal outgrowth within the abnormal brain tracts of zebrafish cyclops mutants. Normally, the earliest differentiating neurons in the zebrafish brain establish a simple scaffold of axonal tracts. Later-developing axons follow cell-specific pathways within this axonal scaffold. In cyclops embryos, t...

BACKGROUND Several potentially important regulators of vertebrate endoderm development have been identified, including Activin-related growth factors and their receptors; transcriptional regulators encoded by the genes Mixer, Xsox17, and HNF3beta; zebrafish One-eyed pinhead (Oep), a member of the Cripto/FRL-1/Cryptic family of epidermal growth factor related proteins (EGF-CFC); and the product ...

Advanced many-core CPU chips already have few hundreds of processing cores (e.g. 160 cores in an IBM Cyclops-64 chip) and as computer architecture progresses, more and more processing cores become available. The underlying runtime systems of such architectures need to efficiently serve hundreds of processors at the same time, requiring all basic data structures within the runtime to maintain un...

Spemann's organizer plays an essential role in patterning the vertebrate embryo. During gastrulation, organizer cells involute and form the prechordal plate anteriorly and the notochord more posteriorly. The fate mapping and gene expression analyses in zebrafish presented in this study reveal that this anteroposterior polarity is already initiated in the organizer before gastrulation. Prechorda...

Our results are the first insight into groundwater copepods of Polish Lowland. The sampling was conducted in 28 wells north-eastern Poland, and Copepoda were present 16 wells. We have identified six species one Cladocera. classified four as stygophiles—Eucyclops serrulatus, Diacyclops bisetosus, crassicaudis, Cyclops furcifer. These frequently found studied different regions often high numbers,...

Abstract In this article, I argue that Judith can be read as imitating book 9 of Homer’s Odyssey , the story Odysseus and Polyphemus Cyclops, in a way compliments its use other literary models (e.g., Genesis 34; Judges 4–5; 1 Kingdoms 17; Homer, Iliad 14). Such an imitation reinforcing narrative’s explicit themes, especially violent opposition to foreign invaders, contributing characterizations...
