Cortical microtubules (MTs) participate in the spatial control of cell expansion and division that is required for plant growth and morphogenesis. Well-ordered transverse cortical MTs promote cell elongation and restrict radial cell expansion. The molecular mechanism controlling their ordering is poorly understood. We report the first known signaling pathway that promotes the organization of co...

E-Government, today, is being regarded as the panacea for many of the conventional government ills, such as rampant corruption in developing countries to costly service deliveries in the developed countries. This paper provides a quick introduction to the e-government and proceeds on to describe a new framework developed for the transition of a government into an egovernment – more specific to ...

This paper proposes several actvites that encourage self-learning in engineering courses. For each actvity, the context and the pedagogical issues addressed are described emphasizing strengths and weaknesses. Specifcally, this work describes and implements fve actvites, which are: questonnaires, conceptual maps, videos, jigsaw and projects. These actvites are applied in seven diferent knowledge...

Methods: In study, mixed design used. single group pre-test post-test weak experimental pattern from among quantitative research methods a case qualitative were cons...

It was a huge honour to be asked to give the Marshall Rosenbluth Memorial Lecture. Having never worked on plasma physics, though, I also feel some diffidence! The closest I’ve ever come has been involvement in some peculiar MHD problems that promise an improved understanding of the solar tachocline — more about confining a magnetic field within a plasma than a plasma within a magnetic field. Be...

Continuous memory leaks severely hurt program performance and software availability for garbage-collected programs. This paper presents a safe method, called LeakSurvivor, to tolerate continuous memory leaks at runtime for garbage-collected programs. Our main idea is to periodically swap out the “Potentially Leaked” (PL) memory objects identified by leak detectors from the virtual memory to dis...

The Jigsaw is a cooperative learning technique in which the class is first divided into expert groups that are assigned different but related tasks. New “home” groups consisting of one memb er from each expert group are then formed. Each expert instructs the other members of this new group about what they have learned. In our application of the jigsaw, we use the expert groups to give students ...

Patch-based appearance models are used in a wide range of computer vision applications. To learn such models it has previously been necessary to specify a suitable set of patch sizes and shapes by hand. In the jigsaw model presented here, the shape, size and appearance of patches are learned automatically from the repeated structures in a set of training images. By learning such irregularly sha...
