When Segregation Hangs by a Thread
The production of haploid gametes is essential for sexual reproduction in most eukaryotes. To achieve this haploid production, germline cells enter a specialized cell cycle called meiosis, in which two consecutive chromosome segregation events create gametes with half the number of chromosomes of diploid cells. Sister chromatids are held together by cohesins along the length of their arms and a...
متن کاملAgrobacterium infection and plant defense—transformation success hangs by a thread
The value of Agrobacterium tumefaciens for plant molecular biologists cannot be appreciated enough. This soil-borne pathogen has the unique capability to transfer DNA (T-DNA) into plant systems. Gene transfer involves both bacterial and host factors, and it is the orchestration of these factors that determines the success of transformation. Some plant species readily accept integration of forei...

We present the design and implementation of Arachne, a threads system that can be interfaced with a communications library for multi-threaded distributed computations. In particular, Arachne supports thread migration between heterogeneous platforms, with dynamic stack size management and recursive thread functions. Arachne is eecient, exible and portable | it is based entirely on C and C++. To ...

In this paper we classify simultaneous multithreaded architectures based on how they select instructions issued in a single cycle. This classiication allows us to study the present trend of technology as well as to explore the new avenues for improvements in simultaneous multithreaded architectures. Based on our classi-cation, we study the impact of various parameters of simultaneous multithrea...
متن کاملArt hangs as science lure
The culmination of artist Aya Ben Ron's six-month residence at the Wellcome Trust in London has been hanging dramatically in the main atrium of the building throughout the summer. The 25-metre-long " Hanging " glistens with kaleidoscopic, colourful images and patterns but on closer scrutiny holds a darker message. The colourful images are revealed to comprise images of various human diseases an...
